 PART I

## Item 1. Business

General

Ramaco Resources, Inc. (the “Company,” “Ramaco,” “we,” “us,” or “our”) is a Delaware corporation formed in October 2016. Our principal corporate and executive offices are located in Lexington, Kentucky with operational offices in Charleston, West Virginia and Sheridan, Wyoming. The Company is an operator and developer of high-quality, low-cost metallurgical coal in southern West Virginia, and southwestern Virginia and is exploring a coal, rare earth and other critical minerals project in Wyoming. Our metallurgical coal development portfolio primarily includes the following properties: Elk Creek, Berwind, Knox Creek, and Maben. We believe each of these properties possesses geologic and logistical advantages that make our coal among the lowest delivered-cost U.S. metallurgical coal to our domestic customer base, North American blast furnace steel mills and coke plants, as well as to international metallurgical coal consumers. In mid-2025, we held a ribbon cutting and groundbreaking event at our rare earth element and critical mineral exploration property near Sheridan, Wyoming (the “Brook Mine”). The Brook Mine is currently an exploration

stage property with respect to its rare earth element and critical mineral operations. The Brook Mine initially produced representative material to serve as feedstock for testing, with the goal of demonstrating the viability of processing rare earth elements and critical minerals and establishing mineral reserves and resources. There is no assurance that we will be able to successfully develop the Brook Mine into a commercial scale mine, and there is no certainty that any part of the inferred mineral resources estimated will be converted into mineral reserves in the future. Contiguous to the Brook Mine, the Company operates a carbon research facility related to the production of advanced carbon products and materials from coal. The Company’s operations are organized into two reportable segments: Metallurgical Coal and Rare Earths and Critical Minerals. See Note 14--Segment Reporting in Item 8, Part II for additional information.

We are an operator and developer of high-quality, low-cost metallurgical coal in southern West Virginia and southwestern Virginia. We maintain 85 million reserve tons and 1,337 million measured and indicated resource tons of high-quality metallurgical coal. We believe our advantaged reserve geology provides us with higher productivity and industry-leading lower cash costs.

As of December 31, 2025, our operations included six active mines at our Elk Creek mining complex (the “Elk Creek Complex”), one active mine at our Berwind mining complex (the “Berwind Complex”), one active mine at our Knox Creek mining complex (the “Knox Creek Complex”), and one active mine at our Maben mining complex (the “Maben Complex”). We maintained four additional mines in idle status across our portfolio of mining complexes that can be reactivated when market conditions warrant.

Development of the Elk Creek Complex commenced in 2016 and included the construction of a preparation plant and rail load-out facilities. The Elk Creek property consists of approximately 20,200 acres of controlled mineral rights and contains approximately 16 seams targeted for production. The Elk Creek Complex produces high-volatile A and B metallurgical coals. Expansion of the Elk Creek preparation plant occurred in 2022 and 2023 in order to increase production, and high-volatile additions at the Elk Creek Complex occurred during 2024, which were fully in production by the end of the third quarter of 2024.

Development of the Berwind Complex began in late 2017. In 2020, we suspended development at the Berwind Complex due to lower pricing and demand largely caused by the COVID-19 outbreak. In early 2021, as pricing and demand improved, Berwind development was restarted. We successfully reached the thicker Pocahontas No. 4 seam in late 2021. The Berwind property consists of approximately 62,500 acres of controlled mineral rights, including the December 2021 acquisition of “Amonate Assets” from subsidiaries of Coronado Global Resources Inc. (“Coronado”) in 2021. The Amonate Assets include a processing plant located in our Berwind Complex, saving us transportation costs to our Knox Creek plant, 26 miles away. The Berwind Complex experienced an ignition event in 2022 that resulted in idling mining operations for one of the active mines. Production restarted for the idle mine in the first quarter of 2023. The Berwind Complex currently produces low-volatile and mid-volatile metallurgical coal. The Company continues to increase production at the main Berwind low-volatile mine.

Our Knox Creek Complex includes a preparation plant and 88,850 acres of controlled mineral rights. The Complex currently produces mid and high-volatile metallurgical coal and also processes and ships coal from other third-party operators. The Company closed its Jawbone mine during 2024, which was nearing the end of its mine life and experiencing higher costs of production. In November 2025, the Company acquired what it refers to as the Russell County property which are contiguous with the Knox Creek complex and which creates an opportunity to significantly increase the coal reserves and resources at Knox Creek.

The Maben Coal acquisition in 2022 provides the Company with 28,000 leased acres of controlled mineral rights, which includes coal deposits that may be mined currently by surface and highwall mining methods as well as developed in the future through deep mining. The Maben Complex currently produces low-volatile metallurgical coal. The Company commissioned a preparation plant at the Maben Complex during 2024 in order to reduce trucking costs.

Our RAM Mine property is located in southwestern Pennsylvania. Following years of delays, the Pennsylvania Department of Environmental Protection issued a denial of the RAM Mine permit during 2023. While the Company believes that the RAM permit was denied incorrectly and capriciously, we will not appeal the denial of the permit and will instead focus on our other core properties and monetize these assets at the appropriate time.

As of December 31, 2025, our estimated aggregate annual production capacity is approximately four million clean tons of coal, excluding our idled properties. We plan to complete development of our existing properties and increase annual production over the next few years to possibly more than seven million clean tons of metallurgical coal annually, subject to market conditions, permitting, and additional capital deployment in the medium-term. We may also acquire additional reserves or infrastructure that contribute to our focus on advantaged geology and lower costs.

Our Brook Mine property consists of approximately 15,800 acres of controlled mineral rights and a research and development facility that were acquired as part of the purchase of Ramaco Coal in 2022. The mine is currently at an exploration stage and is undergoing rigorous third-party testing and analysis to assess the potential for commercial development of rare earth elements and critical minerals.

**Metallurgical Coal Industry**

Metallurgical coal, also known as “met coal” or “coking coal,” is a key component of the blast furnace steelmaking process and, therefore, demand for such coal is highly correlated with conditions in the steel industry. The global metallurgical coal market has grown steadily in recent years and will likely continue to grow over the next few years driven by the industrialization of emerging economies and expansion of urbanization globally.

United States metallurgical coal mines are primarily located in the Appalachian area of the eastern U.S. Imported metallurgical coal has historically been uneconomic due to transportation costs and availability of domestic supply. Metallurgical coal is transported to domestic customers by truck, rail, barge and vessel. Metallurgical coal contracts in North America are typically 12-month, calendar year contracts where both prices and volumes are fixed. These contracts are normally negotiated and entered into during the third and fourth quarters of the preceding calendar year.

U.S. metallurgical coal is also exported to the seaborne market and sold to buyers in Europe, South America, Africa, and Asia. U.S. metallurgical coal exports are sold to buyers in the Atlantic Basin market (customers in Europe, Brazil and Africa) as well as buyers in the Pacific Basin (customers in India, South Korea, Japan and China). U.S. metallurgical coal exports compete with Australian metallurgical coals that are generally produced at a lower cost but are geographically disadvantaged to the Atlantic Basin. Conversely, Australian production has a much shorter logistical route to Pacific Basin customers. Any supply shortfall out of Australia, or increase in global demand beyond Australia’s capacity, has historically been serviced by U.S. and Canadian metallurgical coal producers.

Export metallurgical coal pricing is determined by utilizing a series of indices from a number of independent sources and is adjusted for coal quality. Contracted export volumes have terms that vary in duration from spot cargoes to one year, rarely exceeding one year. In some cases, indices are used to calculate pricing at the point that the coal changes hands. In other cases, an average value of indices over time may be utilized. While the term “benchmark” is still utilized, it too is determined based on index values, typically for the preceding three months.

Metallurgical coals are generally classified as high, medium or low-volatile (“vol”). Volatiles are products, other than water, which are released as gas or vapor when coal is converted to coke. Carbon is the primary element that remains when the volatiles are released.

**Rare Earth Industry**

Rare earth elements are critical enablers of advanced technologies including defense systems, permanent magnets, transportation, electronics, and robotics that have permeated modern society. Rare earth elements have become deeply integrated into the foundation of modern technology and industry and have proven to be difficult to duplicate or replace.

The Company’s Brook Mine is believed to host a rich and unconventional deposit of rare earth elements and critical minerals embedded in coal seams and carbonaceous clays and shales. Based on the latest technical studies, the mine contains both light and heavy magnetic rare earth elements—including neodymium (Nd), praseodymium (Pr), dysprosium (Dy) and terbium (Tb)—which are essential for permanent magnets, lasers, and defense systems. In addition,

the deposit includes high-value critical minerals such as gallium (Ga), germanium (Ge), and scandium (Sc), which are used in semiconductors, aerospace alloys, and advanced communication technologies. The rapid growth and expansion of uses for rare earth elements and critical minerals in modern technologies is expected to drive substantial global demand growth in the years ahead.

Currently, China dominates the rare earth element and critical mineral value chain, controlling a majority of global refining and production capacity, reinforcing the urgency for U.S. domestic development. Growing geopolitical pressures and Chinese export restrictions have intensified U.S. efforts to establish secure rare earth element and critical mineral supply chains, incentivizing entities to develop new domestic deposits.

Our Strategy

Our business strategy is to increase stockholder value through sustained earnings growth, cash flow generation and dividends by:

*Developing and Operating Our Metallurgical Coal Properties.* We have 85 million reserve tons and an additional 1,337 million measured and indicated resource tons of high-quality metallurgical coal with attractive quality characteristics across high-volatility and low-volatility segments. This geologically advantaged resource and reserve base allows for flexible capital spending in challenging market conditions.

We plan to complete development of our existing properties and increase annual production over the next few years to possibly as much as seven million clean tons of metallurgical coal annually, subject to market conditions, permitting, and additional capital deployment in the medium-term. We may also acquire additional reserves or infrastructure that contribute to our focus on advantaged geology and lower costs.

*Being a Low-Cost U.S. Producer of Metallurgical Coal*. Operationally, we are committed to being a low-cost U.S. producer of metallurgical coal. Our reserve base presents advantaged geologic characteristics such as relatively thick coal seams at our deep mines, a low effective mining ratio at our surface mines, and desirable metallurgical coal quality. These characteristics contribute to a production profile that has a cash cost of production that is significantly below most U.S. metallurgical coal producers.

*Maintaining a Conservative Capital Structure and Prudently Managing the Business for the Long Term.* We are committed to maintaining a conservative capital structure and prudently managing the business for the long term, with a reasonable amount of net debt that will afford us the financial flexibility to execute our business strategies on an ongoing basis.

*Enhancing Coal Purchase Opportunities.* Depending on market conditions, we may purchase coal from other independent producers. Purchased coal is complementary from a blending standpoint with our produced coals or it may also be sold as an independent product.

*Demonstrating Excellence in Safety and Environmental Stewardship.* We are committed to complying with both regulatory requirements, as well as our own high standards for environmental responsibility and employee health and safety. We believe that business excellence is achieved through the pursuit of safe and responsible work practices.

*Advancing our Initiatives in Rare Earth Elements, Critical Minerals, and Advanced Carbon Products.* We are also focused on the development of rare earth elements and critical minerals, including gallium, germanium and scandium which are, from time to time subject to strict export licensing requirements and changing destination-specific restrictions (including export bans or restrictions to the United States imposed by the Chinese government), as well as the potential commercialization of coal-to-carbon-based products and materials. These initiatives provide additional growth opportunities in future periods. We had a ribbon cutting and groundbreaking at our rare earth and other critical mineral mine, the Brook Mine, on July 11, 2025. The advancement of this mine and overall project is ongoing.

Our Projects

Our properties are primarily located in southern West Virginia, southwestern Virginia, southwestern Pennsylvania, and northeastern Wyoming. The following map shows the location of our mining complexes and projects, excluding our properties located in Pennsylvania and Wyoming:

​

Elk Creek Mining Complex

Our Elk Creek Complex in southern West Virginia began production in late December 2016. The Elk Creek property consists of approximately 20,200 acres of controlled mineral rights and contains 16 seams that we believe are economically mineable. Nearly all our seams contain high-quality, high-volatile metallurgical coal accessible at or above drainage. Additionally, almost all of this coal is high-fluidity, which is an important factor for high-volatile metallurgical coal.

We control the majority of the coal and related mining rights within the existing permitted areas and our current mine plans, as well as the surface for our surface facilities, through lease agreements with McDonald Land Company among others. We estimate that the Elk Creek Complex contains reserves capable of yielding approximately 29 million

tons of clean saleable metallurgical coal as well as additional measured and indicated metallurgical coal resource tons of 211 million. The current estimated mine life for the Elk Creek Complex is 15 years; however, it is likely that future mines will be planned and scheduled, as necessary, to meet our production goals aligned with market conditions.

We currently market most of the coal produced from the Elk Creek Complex as a blended high-volatile A/B product. When segregated, a portion of our coal can be sold as a high-volatile A product for a premium. Our market for Elk Creek production is North American coke and steel producers as well as European, South American, Asian and African customers, and occasionally to coal traders and brokers for use in filling orders for their blended products. Additionally, we seek to market a portion of our coal in the specialty coal markets that value low ash content.

We process our Elk Creek coal production through the preparation plant located on-site at the complex, which has a heavy-media vessel, large-diameter heavy-media cyclone, dual-stage spiral concentrators, froth flotation, horizontal vibratory and screen bowl centrifuges. Our rail load-out facilities at Elk Creek are served by the CSX railroad; however, we also have the ability to develop on controlled property a rail-loading facility on the Norfolk Southern railroad, which would facilitate dual rail service. We have not yet committed capital for the development of a Norfolk Southern rail facility.

The combined refuse capacity at the active disposal areas is expected to provide over 20 years of disposal life for our operations with additional refuse areas being permitted. We completed construction of a full complement of plate presses during 2020 to allow for dewatering of material which then was being pumped as slurry to our impoundment. This equipment allows us to process all waste material for placement in areas designed for combined refuse disposal and maximize the life for disposal of fine waste rock in the pool of the impoundment.

A large portion of our controlled coal reserves are permitted through existing, issued permits, and we continue actively pursuing multiple new permits.

On January 3, 2020, we entered into a mineral lease with the McDonald Land Company for coal reserves which, in many cases, are located immediately adjacent to our Elk Creek Complex. This leased property became available after the former base lease with another party was terminated. The prior lessee, who controlled the property since 1978, did not produce commercial amounts of coal from the property during their possession of the lease. While it is unusual to have a metallurgical reserve in this part of Central Appalachia remain idle for such an extended period of time, the configuration and location of the tracts lend themselves to be mined and processed far more efficiently from our Elk Creek property. The McDonald reserves have the same geological advantages and low costs that are being experienced in our Elk Creek mines.

During 2022, we began work on a throughput upgrade at our Elk Creek Preparation plant. The upgrade, which was completed in 2023, increased our annual processing capacity for this complex to approximately three million tons per year. In order to utilize the increased capacity, we also began development work on additional low-cost, high- volatile mines at Elk Creek, which were fully in production by the end of the third quarter of 2024.

Berwind Mining Complex

Our Berwind Complex is located on the border of West Virginia and Virginia and is well-positioned to fill the anticipated market for low-volatile coals. The Berwind property consists of approximately 62,500 acres of controlled mineral rights, including the Amonate acquisition. We estimate that the Berwind Complex contains coal reserves capable of yielding approximately 18 million tons of clean saleable metallurgical coal as well as additional measured and indicated metallurgical coal resource tons of 634 million. We estimate that the mine life for the Berwind Complex is over 20 years.

Development of our Berwind Complex began in late 2017 in the thinner Pocahontas No. 3 seam and has since sloped up to mining in the thicker Pocahontas No. 4 seam. In 2020, we suspended development at the Berwind Complex due to lower pricing and demand largely caused by the economic effects of COVID-19. In early 2021, as pricing and demand improved, Berwind development resumed, and we successfully reached the Pocahontas No. 4 seam in late 2021. The Berwind Complex experienced an ignition event during the third quarter of 2022 that resulted in idling mining

operations for one of the active mines. Production restarted for the idle mine in the first quarter of 2023. The Company continues to increase production at the main Berwind low-volatile mine.

We have the necessary permits for the Berwind Complex for our current and budgeted operations. A permit for our Squire Jim seam room-and-pillar underground mine was issued in 2020 and contains a large area of Squire Jim seam coal deposits. The Squire Jim seam of coal is the lowest known coal seam on the geologic column in this region, and due to the depth of cover has never been significantly explored. At this point, we do not anticipate activating this mining permit.

In December 2021, we acquired the Amonate Assets from Coronado, pursuant to an asset purchase agreement. The acquisition included a mine complex located in McDowell County, West Virginia and Tazewell County, Virginia adjacent and contiguous to the Company’s existing Berwind Complex. The assets primarily consist of high-quality, low and mid-volatile metallurgical coal reserves and resources, much of which will be mined from the Company’s Berwind Complex. Also purchased were several additional permitted mines and an idled 1.3 million ton per annum capacity coal preparation plant with a rail loading facility.

We began mine development on the Amonate Assets shortly after acquisition, and production began in the first quarter of 2022. The preparation plant and rail loading facility were refurbished in 2022 and began operation in the fourth quarter of 2022. Rail service is provided by Norfolk Southern.

Knox Creek Mining Complex

The Knox Creek Complex consists of approximately 88,850 acres of controlled mineral rights as well as a preparation plant, a coal-loading facility, and a refuse impoundment. The Complex currently produces mid and high-volatile metallurgical coal and also processes coal purchased from other independent producers from time to time. Rail service is provided by Norfolk Southern.

In the fourth quarter of 2019, we acquired multiple permits from various affiliates of Omega Highwall Mining, LLC. These permits are in close proximity to our Knox Creek preparation plant and loadout infrastructure and provide immediate access to two separate mining areas in Southwestern Virginia. One is a deep mine permit in the Jawbone Seam, a geologically advantaged metallurgical coal reserve and resource. The second is a metallurgical surface mine in the Tiller seam that is mined via surface and highwall mining methods.

In August 2021, we began production at the Big Creek surface mine.

In November of 2025, we acquired certain leases and properties from Coronado Global Resources, Inc., referred to as the Russell County property. These leases are contiguous with the Knox Creek property and preparation plant, and we believe may contain significant tons of high-volatile metallurgical coal. These leases and properties are geologically and logistically advantaged and can potentially extend the physical and economic life of the Knox Creek complex.

Excluding the Russell County property described above, we estimate that the Knox Complex contains reserves capable of yielding approximately 8 million tons of clean saleable metallurgical coal as well as additional measured and indicated metallurgical coal resource tons of 277 million. We estimate that the mine life for the Knox Creek Complex is 30 years. The Company closed its Big Creek Jawbone mine during 2024, which was nearing end of mine life and experiencing higher cost production.

RAM Mine

Following years of delays, the Pennsylvania Department of Environmental Protection issued a denial of the RAM Mine permit in southwest Pennsylvania. While the Company believes that the RAM permit was denied incorrectly and capriciously, we will not appeal the denial of the permit and will instead focus on our other core properties and monetize these assets at the appropriate time.

Maben Complex

The Maben property is located in southern West Virginia and consists of approximately 28,000 acres of controlled mineral rights acquired from the purchase of Maben Coal in the third quarter of 2022. As part of the transaction, we assumed existing mining permits issued by the West Virginia Department of Environmental Protection, which authorizes mining by both surface and highwall mining methods as well as by underground methods. The property also has issued permits covering an existing haul road as well as an active refuse disposal area together with a preparation plant and unit train loadout, neither of which had been constructed as of the closing date. During 2024, the Company completed the purchase of an existing coal preparation plant and relocated the plant to the Company’s Maben Complex, which was commissioned early in the fourth quarter of 2024. The addition of the preparation plant reduced trucking costs subsequent to commissioning.

The Maben property contains various areas of high-quality low-vol metallurgical coal in the Sewell, Beckley, Pocahontas 3, Pocahontas 4, and Pocahontas 6 seams of coal. The Company expects that coal contained in the Sewell seam will be mined by surface and highwall mining methods. Initial production of low-volatile coal began in 2023, and the Company will consider deep mine development of coal contained in Beckley, Pocahontas 3, 4, and 6 seams at a future point.

We estimate that the Maben Complex contains reserves capable of yielding approximately 30 million tons of clean saleable metallurgical coal as well as additional measured and indicated metallurgical coal resource tons of 216 million. The current expected mine life for the Maben Complex is 15 years; however, it is anticipated that future mines will be planned and scheduled, as necessary, from resource areas within the complex, to meet internal production goals aligned with market conditions.

Brook Mine

The property is located in northeastern Wyoming, near Sheridan, and consists of approximately 15,800 acres of controlled mineral rights and a research and development facility that were acquired as part of the purchase of Ramaco Coal during 2022. The property includes a thermal coal deposit as well as a large unconventional deposit of rare earth elements and other critical minerals sourced from coal and carbonaceous feed material. This property is also being used to support the Company’s possible expansion into the manufacture and commercialization of advanced carbon products and materials from coal.

A mineral resource estimate was released for the Brook Mine in September 2025 based on a Technical Report Summary of the Brook Mine completed by Weir International Inc. (“Weir”), which was subsequently revised in July 2026 (which is current as of December 31, 2025) (the “TRS”) and is filed as Exhibit 96.5 hereto. The TRS utilizes certain project-specific technical information included in a conceptual study (the “Fluor Study”) completed by Fluor Corporation (“Fluor”). The Fluor Study was not prepared in accordance with Regulation S-K Subpart 1300 requirements. The mineral resource estimates are not mineral reserves and do not meet the threshold for reserve modifying factors that would allow for conversion to mineral reserves. There is no certainty that any part of the mineral resource estimates will be converted into mineral reserves.

Preliminary findings indicate elevated concentrations of a number of rare earth elements and critical minerals which include heavy magnetic rare earth elements, like terbium and dysprosium, and other critical minerals, like gallium, germanium and scandium. The Company continues to develop its processing approach for critical minerals and rare earth elements within the current Brook Mine permit area.

Customers and Contracts

Coal prices differ substantially by region and are impacted by many factors including the overall economy, demand for steel, demand for electricity, location, market, quality and type of coal, mine operation costs and the cost of customer alternatives. The major factors influencing our business are the global economy and demand for steel.

We market our production to North American integrated steel mills and coke plants as well as international customers in Europe, South America, Asia, and Africa. Additionally, we market limited amounts of our production to various premium-priced specialty markets, such as foundry cokemakers, manufacturers of activated carbon products, and specialty metals producers.

Coal quality and volumes are stipulated in coal sales agreements, and, in many cases, the annual pricing and volumes are fixed. Our contracts with customers typically require us to deliver coal with minimum specifications or qualities. Variances from these specifications or qualities are settled by employing price adjustments.

Generally, the Company’s domestic sales contracts have terms of about one year and the pricing is typically fixed. Export sales have spot or term contracts, and pricing can be either fixed or derived from index-based pricing mechanisms.

We sold 3.8 million tons of coal during 2025 and recognized $536.6 million of revenue. Of this amount, 37% of our revenue was from sales into North American markets and 63% of our revenue was from sales into export markets. During 2025, sales to three customers accounted for approximately 34% of total revenue. No other customer accounted for 10% or more of our total revenue during 2025. If a major customer decided to stop purchasing coal or significantly reduced its purchases from us, revenue could decline and our operating results and financial condition could be adversely affected.

Trade Names, Trademarks and Patents

We do not have any registered trademarks or trade names for our traditional products and services or subsidiaries, nor do we believe that any trademark or trade name is material to our metallurgical coal business. The names of the seams in which we have coal reserves, and attributes thereof, are widely recognized in the metallurgical coal market. However, trademarks related to our advanced carbon products business could become material depending on future developments, of which there are four registered trademarks and seven pending trademark applications.

In connection with our advanced carbon products business, the Company holds more than 70 intellectual property patents and pending applications related to the conversion of low-cost carbon feed material into higher-value carbon products as well as exclusive licensing agreements, all of which have a remaining duration of 14-20 years.

Competition

Our principal domestic coal competitors include Alpha Metallurgical Resources, Inc., Blackhawk Mining, LLC, Coronado Global Resources Inc., Arch Resources, Inc. (now a subsidiary of Core Natural Resources), Peabody Energy Corporation, and Warrior Met Coal, Inc. We also compete in international markets directly with domestic companies and with companies that produce coal from one or more foreign countries, such as Australia, Canada, and Colombia. Many of these coal producers are larger than we are and have greater financial resources and larger reserve bases than we do.

​

Additionally, the Company faces, or is expected to face, competition both domestically and globally in the rare earth element and other critical mineral market. China accounts for the significant majority of global rare earth element and other critical mineral production and also dominates the manufacture of metals from rare earth elements, capabilities that are not currently present at scale in the U.S. There is potential competition from emerging players within the rare earth element and other critical mineral market.

​

Suppliers

Supplies used in our business include petroleum-based fuels, explosives, tires, conveyance structure, ventilation supplies, lubricants and other raw materials as well as spare parts and other consumables used in the mining process. We use third-party suppliers for a significant portion of our equipment rebuilds and repairs, drilling services and construction. We believe adequate substitute suppliers and contractors are available, and we are not dependent on any one supplier or contractor. We continually seek to develop relationships with suppliers and contractors that focus on reducing our costs while improving quality and service.

Environmental, Health and Safety and Other Regulatory Matters

Our operations are subject to numerous federal, state, and local environmental, health and safety laws and regulations, such as those relating to permitting and licensing matters, employee health and safety, reclamation and restoration of mining properties, water discharges, air emissions, plant and wildlife protection, the storage, treatment and disposal of certain materials (including solid and hazardous wastes), remediation of contaminated sites, surface subsidence from underground mining and the effects of mining on surface water and groundwater conditions.

Compliance with these laws and regulations may be costly and time-consuming, delay the commencement, continuation or expansion of exploration or production at our facilities, and depress demand for our products by imposing more stringent requirements and limits on our customers’ operations. Moreover, these laws are constantly evolving, and the trend has been for increasingly complex and stringent regulation over time. New legislative or administrative proposals, changes in administrative and judicial interpretations of existing laws and regulations related to the protection of the environment could result in substantially increased capital, operating and compliance costs.

Due in part to these extensive and comprehensive regulatory requirements and ever-changing interpretations of these requirements, violations of these laws can occur from time to time in our industry and also in our operations. Expenditures relating to environmental compliance are a major cost consideration for our operations and safety and compliance is a significant factor in mine design, both to meet regulatory requirements and to minimize long-term environmental liabilities.

The following is a summary of the various federal and state environmental and similar laws and regulations that have a material impact on our business.

*Surface Mining Control and Reclamation Act.* The Surface Mining Control and Reclamation Act of 1977 (the “SMCRA”) establishes comprehensive operational, reclamation and closure standards for our mining operations and requires that such standards be met during the course of and following completion of mining activities. The SMCRA also stipulates compliance with many other major environmental statutes, including the Clean Air Act (the “CAA”), the Clean Water Act (the “CWA”), the Endangered Species Act (the “ESA”), the Resource Conservation and Recovery Act (the “RCRA”) and the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (the “CERCLA”). Permits for all mining operations must be obtained from the United States Office of Surface Mining Reclamation and Enforcement (the “OSMRE”) or, where state regulatory agencies have adopted federally approved state programs under SMCRA. Our operations are located in West Virginia and Virginia, which have each individually achieved primacy to regulate and enforce surface mining and reclamation operations within the respective state to ensure compliance with SMCRA.

The SMCRA imposes a complex set of requirements covering all facets of coal mining. SMCRA regulations govern, among other things, coal prospecting, mine plan development, topsoil or growth medium removal and replacement, disposal of excess spoil and coal refuse, protection of the hydrologic balance, and suitable post mining land uses.

From time to time, the OSMRE will also update its mining regulations under the SMCRA. For example, in 2025 the OSMRE rescinded several regulations regarding abandoned mine lands, permanent program performance standards, and prior balance replacement funds. Congressional amendment of the SMRCA, existing rules, or changes to SMCRA regulations, could result in additional material costs, obligations and restrictions upon our operations.

*Abandoned Mine Lands Fund.* The SMCRA also imposes a reclamation fee on all current mining operations, to fund the Abandoned Mine Reclamation Fund (the “AML Fund”). The fees through September 30, 2034 are (i) 22.4 cents per ton for surface-mined anthracite, bituminous, and subbituminous coal if the value per ton is $2.24 per ton or more, (ii) 9.6 cents per ton for underground-mined anthracite, bituminous, and subbituminous coal if the value per ton is $0.96 per ton, and (iii) 6.4 cents per ton for surface- and underground-mined lignite coal if the value per ton is $3.20 per ton or more, as set by the OSMRE Final Rule effective August 24, 2022. Estimates of our total reclamation and mine-closing liabilities are based upon permit requirements and our experience related to similar activities. If these accruals are

insufficient or our liability in a particular year is greater than currently anticipated, our future operating results could be adversely affected.

*Mining Permits and Approvals.* Numerous governmental permits and approvals are required for mining operations. We are required to prepare and present to federal, state, and local authorities data detailing the effect or impact that any proposed exploration project for production of coal may have upon the environment, the public and our employees. The permitting rules are complex and continuously updated and may be subject to discretionary interpretations by regulators. Further, the laws, rules, and regulations that govern our mining operations authorize substantial fines and penalties, including revocation or suspension of mining permits under some circumstances. Monetary sanctions and, in certain circumstances, even criminal sanctions may be imposed for failure to comply with these laws. Compliance with required permits and associated regulations may have a material adverse impact on our operations, earnings, or financial condition.

Applications for permits and permit renewals associated with our mining operations are also subject to public comment and potential legal challenges from third parties seeking to prevent a permit from being issued, or to overturn the applicable agency’s grant of the permit. Should our permitting efforts become subject to such challenges, the permits may not be issued in a timely fashion, may impose requirements which restrict our ability to conduct our mining operations or to do so profitably, or may not be issued at all. Any delays, denials, or revocation of these or other similar permits we need to operate could reduce our production and materially adversely impact our cash flow and results of our operations.

In order to obtain mining permits and approvals from state regulatory authorities, mine operators must also submit a reclamation plan for restoring the mined property to its prior condition, productive use or other permitted condition. The conditions of certain permits also require that we obtain surface-owner consent if the surface estate has been split from the mineral estate. This requires us to negotiate with third parties for surface access that overlies coal we acquired or intend to acquire. These negotiations can be costly and time-consuming, lasting years in some instances, which can create additional delays in the permitting process. If we cannot successfully negotiate for land access, we could be denied a permit to mine coal we already own.

Finally, we typically submit necessary mining permit applications several months, or even years, before we anticipate mining a new area. However, we cannot control the pace at which the government issues permits needed for new or ongoing operations. For example, the process of obtaining CWA permits can be particularly time-consuming and subject to delays and denials and generally involves multiple levels of agency review. The Environmental Protection Agency (the “EPA”) also has the authority to veto permits issued by the U.S. Army Corps. of Engineers (the “Corps”) under the CWA’s Section 404 program that prohibits the discharge of dredged or fill material into regulated waters without a permit. And for many permit applications, the Corps is required to review the proposed activity under the National Environmental Policy Act (“NEPA”), which can involve the preparation of lengthy and complex environmental assessments or environmental impact statements. Even after we obtain the permits that we need to operate, many of the permits must be periodically renewed, or may require modification. There is some risk that not all existing permits will be approved for renewal, or that existing permits will be approved for renewal only upon terms that restrict or limit our operations in ways that may be material.

*Financial Assurance.* Federal and state laws require a mine operator to secure the performance of its reclamation and lease obligations under the SMCRA through the use of surety bonds or other approved forms of financial security for payment of certain long-term obligations, including mine closure or reclamation costs. It is possible that future revisions to various financial assurance requirements may increase the amount of financial assurance needed and limit the types of acceptable instruments, straining the capacity of the surety markets to meet demand. This may delay the timing for and increase the costs of obtaining the required financial assurance.

We use surety bonds, trusts and letters of credit to provide financial assurance for certain transactions and business activities. Federal and state laws require us to obtain surety bonds to secure payment of certain long-term obligations including mine closure or reclamation costs and other miscellaneous obligations. The bonds are renewable on a yearly basis. Surety bond rates have increased in recent years and the market terms of such bonds have generally become less favorable. Sureties typically require coal producers to post collateral, often having a value equal to 40% or

more of the face amount of the bond. As a result, we may be required to provide collateral, letters of credit or other assurances of payment in order to obtain the necessary types and amounts of financial assurance. Under our surety bonding program, we are not currently required to post any letters of credit or other collateral to secure the surety bonds; obtaining letters of credit in lieu of surety bonds could result in a significant cost increase. Moreover, the need to obtain letters of credit may also reduce amounts that we can borrow under any senior secured credit facility for other purposes. If, in the future, we are unable to secure surety bonds for these obligations and are forced to secure letters of credit indefinitely or obtain some other form of financial assurance at too high of a cost, our profitability may be negatively affected.

We intend to maintain a credit profile that precludes the need to post collateral for our surety bonds. Nonetheless, our surety has the right to demand additional collateral at its discretion.

Some international customers require new suppliers to post performance guarantees during the initial stages of qualifying to become a long-term supplier. To date we have not had to provide a performance guarantee, but it is possible that such a guarantee could be required in the future.

*Mine Safety and Health.* The Federal Mine Safety and Health Act of 1977, as amended (the “MINE Act”) and the Mine Improvement and New Emergency Response Act of 2006 (the “MINER Act”), and regulations issued under these federal statutes, impose stringent health and safety standards on mining operations. The regulations that have been adopted under the Mine Act and the MINER Act are comprehensive and affect numerous aspects of mining operations, including training of mine personnel, mining procedures, roof control, ventilation, blasting, use and maintenance of mining equipment, dust and noise control, communications, emergency response procedures, and other matters. The Mine Safety and Health Administration (the “MSHA”) regularly inspects mines to ensure compliance with regulations promulgated under the Mine Act and MINER Act.

Pennsylvania, West Virginia, Virginia and Wyoming all have similar programs for mine safety and health regulation and enforcement. The various requirements mandated by federal and state statutes, rules, and regulations place restrictions on our methods of operation and result in fees and civil penalties for violations of such requirements or criminal liability for the knowing violation of such standards, significantly impacting operating costs and productivity. Changes to state laws and regulations may limit operations or increase operational costs.

The regulations enacted under the Mine Act and MINER Act as well as under similar state acts are routinely expanded, made more stringent, or otherwise modified, impacting compliance costs and potential liability. For example, MSHA issued a final rule (89 Fed. Reg. 28218, April 18, 2024) enacting more stringent requirements to protect miners exposed to respirable crystalline silica. Our compliance with current or future mine health and safety regulations could increase our mining costs. At this time, it is not possible to predict the full effect that new or proposed statutes, regulations and policies will have on our operating costs, but any expansion of existing regulations, or making such regulations more stringent, may have a negative impact on the profitability of our operations. If we were to be found in violation of mine safety and health regulations, we could face penalties or restrictions that may materially and adversely impact our operations, financial results and liquidity.

In addition, government inspectors have the authority to issue orders to shut down our operations based on safety considerations under certain circumstances, such as imminent dangers, accidents, failures to abate violations, and unwarrantable failures to comply with mandatory safety standards. If an incident were to occur at one of our operations, it could be shut down for an extended period of time, and our reputation with prospective customers could be materially damaged. Moreover, if one of our operations is issued a notice of pattern of violations, then MSHA can issue an order withdrawing the miners from the area affected by any enforcement action during each subsequent significant and substantial (“S&S”) citation until the S&S citation or order is abated.

*Workers’ Compensation and Occupational Disease.* We are insured for workers’ compensation benefits for work related injuries that occur within our United States operations. We retain insurance coverage for all of our subsidiaries and are insured for the statutory limits. Workers’ compensation liabilities, including those related to claims incurred but not reported, are recorded principally using annual valuations based on discounted future expected payments using historical data of the operating subsidiary or combined insurance industry data when historical data is

limited. State workers’ compensation acts typically provide for an exception to an employer’s immunity from civil lawsuits for workplace injuries in the case of intentional torts. However, West Virginia’s workers’ compensation act provides a much broader exception to workers’ compensation immunity. The exception allows an injured employee to recover against his or her employer where he or she can show damages caused by an unsafe working condition of which the employer was aware that was a violation of a statute, regulation, rule or consensus industry standard. These types of lawsuits are not uncommon and could have a significant impact on our operating costs.

In addition, we obtained from a third-party insurer a workers’ compensation insurance policy, which includes coverage for medical and disability benefits for occupational disease under the Federal Coal Mine Health and Safety Act of 1969 and the Mine Act. Under the Black Lung Benefits Revenue Act of 1977 and the Black Lung Benefits Reform Act of 1977, as amended in 1981, each coal mine operator must pay federal black lung benefits to claimants who are current and former employees and also make payments to a trust fund for the payment of benefits and medical expenses to claimants who last worked in the coal industry prior to January 1, 1970.

The Patient Protection and Affordable Care Act of 2010 includes significant changes to the federal black lung program including establishing an automatic survivor benefit paid upon the death of a miner with an awarded black lung claim and a rebuttable presumption of pneumoconiosis among miners with 15 or more years of coal mine employment that are totally disabled by a respiratory condition. These changes could materially impact our costs associated with the federal black lung program. In addition to possibly incurring liability under federal statutes, we may also be liable under state laws for black lung claims.

*Clean Air Act.* The CAA and comparable state laws that regulate air emissions affect coal mining operations both directly and indirectly. Direct impacts on coal mining and processing operations include CAA permitting requirements and emission control requirements relating to air pollutants, including particulate matter such as fugitive dust. The CAA indirectly impacts coal mining operations by extensively regulating the emissions of particulate matter, sulfur dioxide, nitrogen oxides, mercury and other compounds emitted by coal-fired power plants. In addition to the greenhouse gas (“GHG”) issues discussed below, the air emissions programs that may materially and adversely affect our operations, financial results, liquidity, and demand for our coal, directly or indirectly, include, but are not limited to, the following:

- *Cross-State Air Pollution Rule.* In July 2011, the EPA finalized the Cross-State Air Pollution Rule (the “CSAPR”), a cap-and-trade program that requires 28 states in the Midwest and eastern seaboard of the U.S. to reduce power plant emissions that contribute to interstate ozone and/or fine particle pollution. A September 2016, update to CSAPR further limited summertime (May-September) nitrogen oxide emissions from power plants in 22 states in the eastern United States beginning in May 2017 (the “CSAPR Update Rule”). After the United States Court of Appeals for the District of Columbia Circuit remanded the CSAPR Rule Update in 2019 for failing to require timely upwind reductions under the Clean Air Act, EPA finalized a Revised CSAPR Rule Update in April 2021 that resolved transport obligations for 21 states and imposed additional NOx reductions in 12 states. These requirements may accelerate the retirement of coal-fired electric generating units, or require the installation of necessary emission control technologies, reducing demand for thermal coal. Separately, in February 2023, EPA found that 21 states’ state implementation plans (SIPs) did not protect downwind states from interstate ozone, leading to EPA’s finalizing a federal implementation Plan (FIP) in March 2023 under the CAA’s Good Neighbor requirements, referred to as the Good Neighbor Plan rule for the 2015 ozone National Ambient Air Quality Standards (“NAAQS”). The Good Neighbor Plan rule implemented nitrogen oxide (“NOx”) limits on power plants and, for the first time, industrial sources, in 23 states. Litigation followed, and the Supreme Court’s stayed enforcement of the Good Neighbor Plan in Ohio v. EPA. In November 2024, EPA issued an interim final rule (89 Fed. Reg. 87960 (Nov. 6, 2024) confirming that the Good Neighbor Plan is stayed nationwide.
- *Acid Rain*. Title IV of the CAA requires reductions of sulfur dioxide emissions by electric utilities and applies to all existing coal-fired power plants generating greater than 25 megawatts of power and all new coal-fired generating units. Affected power plants have sought to reduce sulfur dioxide emissions by switching to lower sulfur fuels, installing pollution control devices, reducing electricity generating levels or

purchasing or trading sulfur dioxide emission allowances. These reductions could impact our customers in the electric generation industry. These requirements are not supplanted by the CSAPR.

- *NAAQS for Criterion Pollutants.* The CAA requires the EPA to set standards, referred to as the NAAQS, for six common air pollutants: carbon monoxide, nitrogen dioxide, lead, ozone, particulate matter (“PM”) and sulfur dioxide. Areas that are not in compliance (referred to as “non-attainment areas”) with these standards must take steps to reduce emissions levels. The EPA has adopted NAAQS for carbon monoxide, nitrogen dioxide, lead, sulfur dioxide, PM and ground-level ozone. The CAA further requires the EPA to periodically review and revise the NAAQS, possibly resulting in more stringent standards over time. States with non-attainment areas must adopt a state implementation plan that demonstrates compliance with the existing or new air quality standards. These plans could require significant additional emissions control expenditures at coal-fired power plants. New rules and standards may also impose additional emissions control requirements on our customers in the electric generation, steelmaking, and coke industries. Because coal mining operations emit particulate matter and sulfur dioxide, our mining operations could be affected when the new standards are implemented by the states.

​

- *Mercury and Hazardous Air Pollutants*. The EPA has established emission standards for mercury and other metals, fine particulates, and acid gases from coal- and oil-fired power plants through the Mercury and Air Toxics Standards (“MATS”) rule. In April 2024, EPA issued a final rule further strengthening MATS emission standards pertaining to mercury, toxic metals and filterable particulate matter. In June 2025, EPA proposed a repeal to this rule. No final action has been taken on the proposed appeal. Like CSAPR, MATS and other similar future regulations could accelerate the retirement of a significant number of coal-fired power plants. Such retirements would likely adversely impact our business.

*Global Climate Change –* Climate change continues to attract considerable public and scientific attention. There is widespread concern about the contributions of human activity to such changes, especially through the emission of GHGs. Numerous reports from scientific and governmental bodies such as the United Nations Intergovernmental Panel on Climate Change have expressed heightened concerns about the impacts of human activity, especially fossil fuel combustion, on the global climate. There are three primary sources of GHGs associated with the coal industry. First, the end use of our coal by our customers in electricity generation, coke plants, and steelmaking is a source of GHGs. Second, combustion of fuel by equipment used in coal production and to transport our coal to our customers is a source of GHGs. Third, coal mining itself can release methane, which is considered to be a more potent GHG than carbon dioxide, directly into the atmosphere. These emissions from coal consumption, transportation and production are subject to pending and proposed regulation as part of initiatives to address global climate change.

As a result, numerous proposals have been made and are likely to continue to be made at the international, national, regional, state and local levels of government to monitor and limit emissions of GHGs. Collectively, these initiatives could result in higher electric costs to our customers or lower the demand for coal used in electric or steel generation, which could in turn adversely impact our business.

At present, we are principally focused on metallurgical coal production, which is not used in connection with the production of power generation. However, we may seek to sell greater amounts of our coal into the power-generation market in the future. The market for our coal may be adversely impacted if comprehensive legislation or regulations focusing on GHG emission reductions are adopted, or if our customers are unable to obtain financing for their operations.

At the international level, in April 2016, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France, which resulted in an agreement intended to nationally determine their contributions and set GHG emission reduction goals every five years beginning in 2020. In November 2019, plans were formally announced for the U.S. to withdraw from the Paris Agreement with an effective exit date in November 2020. In early 2021, President Biden announced reentry of the U.S. into the Paris Agreement and issued a series of executive orders designed to address climate change. In January 2025, President Trump rescinded climate-related executive orders issued by President Biden and initiated the United States’ withdrawal from the Paris Agreement, which was finalized on January 27, 2026. Global initiatives – including

the 2021 Glasgow Climate Pact, which aims to cut global methane pollution at least 30% by 2030 relative to 2020 levels, including “all feasible reductions” in the energy sector and the multi-lateral Global Coal to Clean Energy Transition Statement (signed by 46 countries), committing to phaseout of unabated coal power generation by about 2030 for “major economies” and 2040 globally – signal sustained international pressure to transition away from coal. At the 27th conference of parties (“COP27”), President Biden announced the EPA’s proposed standards to reduce methane emissions from existing oil and gas sources, and agreed, in conjunction with the European Union and a number of other partner countries, to develop standards for monitoring and reporting methane emissions to help create a market for low methane-intensity natural gas. Even as federal action has fluctuated, state and local governments have publicly committed to furthering the goals of the Paris Agreement. International commitments, potential future reentry into the Paris Agreement and state or local action may result in the development of additional regulations or changes to existing regulations that may impact our business.

The $1 trillion legislative infrastructure package passed by Congress in November 2021 includes a number of climate-focused spending initiatives targeted at climate resilience, enhanced response and preparation for extreme weather events, and clean energy and transportation investments, though certain climate-focused elements were subsequently curtailed by the 2025 One Big Beautiful Bill Act (the “OBBBA”). The Inflation Reduction Act of 2022 provides significant funding and incentives for research and development of low-carbon energy production methods, carbon capture, and other programs directed at addressing climate change. The Inflation Reduction Act of 2022 also provides significant funding for research and development of low-carbon energy production methods, carbon capture, and other programs directed at addressing climate change.

In 2009 EPA issued a finding that GHGs present an endangerment to public health and the environment, because emissions of GHGs are, according to the EPA, contributing to the warming of the earth’s atmosphere and other climatic changes. Based on these findings, the EPA, over time, has attempted to restrict emissions of GHGs under existing provisions of the CAA. For example, the Clean Power Plan (the “CPP”) to cut carbon emissions from existing power plants was finalized in 2015 but was subsequently stayed by the U.S. Supreme Court. The CPP was rescinded and replaced in July 2019, by the Affordable Clean Energy Rule (the “ACE Rule”), which required states to set appropriate GHG emission standards for power plants within their jurisdiction based upon the application of “candidate” heat rate improvement measures. In January 2021, the D.C. Circuit vacated the ACE Rule and remanded it to the agency for further proceedings. In February 2021, the EPA issued a memorandum stating the agency’s position that neither the Clean Power Plan nor the ACE Rule are in effect, and future regulation of carbon dioxide emissions from existing power generation facilities remains uncertain In May 2024, EPA finalized GHG new source performance standards (“NSPS”) for new gas-fired power plants and existing coal-fired power plants (89 Fed. Reg. 39798 (May 9, 2024), and the Supreme Court declined to stay that rule in October 2024. Under the Trump Administration, EPA has proposed repealing power-sector GHG standards and rescinding the GHG endangerment finding, but those proposals remain pending and may face legal challenges, if finalized. The continued operation of GHG emission standards and any future rules or future GHG emission standards may encourage a shift away from coal-fired power generation, adversely impacting the market for our product.

Additionally, on March 6, 2024, the SEC adopted final rules to require registrants to disclose certain climate-related information in registration statements and annual reports. The final rules will require the Company to disclose, among other things, material climate-related risks, information about our board of directors’ (“Board”) oversight of climate-related risks, management’s role in managing material climate-related risks, and Scope 1 and Scope 2 greenhouse gas emissions. Compliance with these rules will be phased in over time based on our filing status as well as the content of the disclosure and assurance requirements. Any implementation of the rule is currently stalled. On April 4, 2024, the SEC issued an order to stay the rule in response to legal challenges, which have been consolidated under the Eighth Circuit U.S. Court of Appeals. After the SEC under the current administration indicated it did not plan to defend or reconsider the rule, the Eight Circuit further held the appeal in abeyance until the SEC defends the appeal or reconsiders the rule. If upheld and implemented, the rule may result in increased legal, accounting, and other compliance-related costs, as well as place strain on our personnel, systems, and resources.

At the state level, several states, including Pennsylvania and Virginia, have already adopted measures requiring GHG emissions to be reduced within state or regional boundaries, including cap-and-trade programs and the imposition of renewable energy portfolio standards. Various states and regions have also adopted GHG initiatives, and certain

governmental bodies have imposed, or are considering the imposition of, fees or taxes based on the emission of GHGs by certain facilities. A number of states have also enacted legislative mandates requiring electricity suppliers to use renewable energy sources to generate a certain percentage of power. Furthermore, many state and local leaders have intensified or stated their intent to intensify efforts to support international climate commitments and treaties.

The extent of future regulation of GHG emissions may inhibit utilities from investing in the building of new coal-fired plants to replace older plants or investing in the upgrading of existing coal-fired plants. Any reduction in the amount of coal consumed by electric power generators as a result of actual or potential regulation of GHG emissions could decrease demand for thermal coal, thereby reducing our revenue and adversely affecting our business and results of operations. We or our prospective customers may also have to invest in carbon dioxide capture and storage technologies in order to burn coal and comply with future GHG emission standards.

Finally, there have been attempts to encourage the reduction of coalbed methane emissions because methane has a greater GHG effect than carbon dioxide and can give rise to safety concerns. For example, the EPA has established the Coalbed Methane Outreach Program in an effort to mitigate methane emissions from underground coal mines through voluntary initiatives and outreach in partnership with the coal industry. If new laws or regulations were introduced to reduce coalbed methane emissions, those rules could adversely affect our costs of operations by requiring installation of air pollution controls, higher taxes, or costs incurred to purchase credits that permit us to continue operations.

*Clean Water Act.* The CWA and corresponding state laws and regulations affect coal mining operations by restricting the discharge of pollutants, including dredged or fill materials, into waters of the United States. Likewise, permits are required under the CWA to construct impoundments, fills or other structure in areas that are designated as waters of the United States. For example, prior to placing fill material in waters of the United States, such as with the construction of a valley fill, coal mining companies are required to obtain a permit from the Corps under Section 404 of the CWA. The EPA has the authority to veto permits issued by the Corps under the CWA’s Section 404 program that prohibits the discharge of dredged or fill material into regulated waters without a permit. Additionally, recent court decisions, regulatory actions and proposed legislation have created uncertainty over CWA jurisdiction and permitting requirements, such as (1) an April 2020 decision further defining the scope of the CWA, wherein the U.S. Supreme Court held that, in certain cases, discharges from a point source to groundwater could fall within the scope of the CWA and require a permit and (2) a May 2023 decision further defining the scope of the CWA, wherein the U.S. Supreme Court held that discharges from a point source to a wetland could fall within the scope of the CWA and require a permit if the adjacent body of water is a relatively permanent body of water connected to traditional interstate navigable waters and the wetland has a continuous surface connection with that water.

Prior to discharging any pollutants into waters of the United States, coal mining companies must obtain a CWA National Pollutant Discharge Elimination System (“NPDES”) permit from the appropriate state or federal permitting authority. NPDES permits include effluent limitations for discharged pollutants and other terms and conditions, including required monitoring of discharges. Failure to comply with the CWA permits can lead to the imposition of significant penalties, litigation, compliance costs and delays in coal production. Potential changes in state and federally recommended water quality standards may result in the issuance or modification of permits with new or more stringent effluent limits or terms and conditions. For instance, waters designated by states as impaired (i.e., as not meeting current water quality standards) are subject to Total Maximum Daily Load (“TMDL”) regulations, which may lead to the adoption of more stringent discharge standards for our coal mines and could require more costly treatment. Likewise, the water quality of certain receiving streams requires an anti-degradation review before approving any discharge permits. TMDL regulations and anti-degradation policies may increase the cost, time and difficulty associated with obtaining and complying with NPDES permits. In addition, in certain circumstances private citizens may challenge alleged violations of NPDES permit limits in court. Recently, certain citizen groups have filed lawsuits alleging ongoing discharges of pollutants, including selenium and conductance, from valley fills located at certain mining sites in some of the regions where we operate. In West Virginia, several of these cases have been successful for the challengers. While it is difficult to predict the outcome of any potential or future suits, such litigation could result in increased compliance costs following the completion of mining at our operations.

Finally, in June 2015, the EPA and the Corps published a new definition of “waters of the United States” (“WOTUS”) that would have expanded areas requiring NPDES or Corps Section 404 permits. This definition never took effect as it was replaced by the Navigable Waters Protection Rule (the “NWPR”) in December 2019. A coalition of states and cities, environmental groups and agricultural groups challenged the NWPR, which was vacated by the U.S. District Court for the District of Arizona in August 2021. In December 2022, the EPA and Corps announced the final “Revised Definition of ‘Waters of the United States’” rule. This rule is not currently operative in certain states and for certain parties due to ongoing litigation. In August 2023, the EPA and Corps issued a final rule to amend the “Revised Definition of ‘Waters of the United States’” rule in response to the U.S. Supreme Court’s May 2023 decision in the case of Sackett v. Environmental Protection Agency. In the jurisdictions and for the parties where the January 2023 rule is enjoined, the EPA and Corps are interpreting “waters of the United States” consistent with the U.S. Supreme Court’s decision in Sackett and the pre-2015 regulatory regime. In November 2025, EPA and the Army Corps published a proposed rule to revise the definition of WOTUS to (1) define key phrases articulated by the Court in its seminal Sackett decision, (2) further define certain regulatory exemptions to the waters covered by the Act, and (3) implement additional conforming changes. To the extent a new rule or further litigation expands the scope of the CWA’s jurisdiction, the CWA permits we need may not be issued, may not be issued in a timely fashion, or may be issued with new requirements which restrict our ability to conduct mining operations or to do so profitably.

*Resource Conservation and Recovery Act.* The RCRA and corresponding state laws establish standards for the management of solid and hazardous wastes generated at our various facilities. Besides affecting current waste disposal practices, the RCRA also addresses the environmental effects of certain past hazardous waste treatment, storage and disposal practices. In addition, the RCRA requires certain of our facilities to evaluate and respond to any past release, or threatened release, of a hazardous substance that may pose a risk to human health or the environment.

The RCRA may affect coal mining operations by establishing requirements for the proper management, handling, transportation and disposal of solid and hazardous wastes. For example, the EPA regulates coal ash as a solid waste under Subtitle D of the RCRA through its coal combustion residuals (“CCR”) rule. This rule establishes limits for the location of new sites and requires closure of sites that fail to meet prescribed engineering standards, regular inspections of impoundments, and immediate remediation and closure of unlined ponds that are polluting ground water. Additionally, in December 2016, Congress passed the Water Infrastructure Improvements for the Nation Act, which provided for the establishment of state and EPA permit programs for the control of CCR and authorizes states to incorporate the EPA’s final rule for CCR or develop other criteria that are at least as protective as the final rule. In May 2024, the EPA finalized regulations for legacy CCR surface impoundments and coal ash disposed in areas outside of regulated units including certain previously closed surface impoundments and landfills. The current requirements of the CCR rules, as well as any future changes in the management of CCR, could increase our customers’ operating costs and potentially reduce their ability or need to purchase coal. In addition, contamination caused by the past disposal of CCR, including coal ash, could lead to material liability for our customers under the RCRA or other federal or state laws and potentially further reduce the demand for coal.

Currently, certain coal mine wastes, such as earth and rock covering a mineral deposit (commonly referred to as overburden) and coal cleaning wastes, are exempted from hazardous waste management under the RCRA. Any change or reclassification of this exemption could significantly increase our coal mining costs.

*Comprehensive Environmental Response, Compensation and Liability Act.* CERCLA and similar state laws affect coal mining operations by, among other things, imposing cleanup requirements for threatened or actual releases of hazardous substances into the environment. Under CERCLA and similar state laws, joint and several liability may be imposed on hazardous substance generators, site owners, transporters, lessees and others regardless of fault or the legality of the original disposal activity. Although the EPA excludes most wastes generated by coal mining and processing operations from the primary hazardous waste laws, such wastes can, in certain circumstances, constitute hazardous substances for the purposes of CERCLA. In addition, the disposal, release or spilling of some products used by coal companies in operations, such as chemicals listed as hazardous substances under CERCLA, could trigger the liability provisions of CERCLA or similar state laws. The EPA periodically evaluates the CERCLA list of hazardous substances and updates this list. The addition of new substances to CERCLA’s hazardous substance list may result in increased costs to cleanup properties at which the listed substances are released or pose the threat of release.

We may be subject to liability under CERCLA and similar state laws for coal mines that we currently own, lease or operate or that we or our predecessors have previously owned, leased or operated, and sites to which we or our predecessors sent hazardous substances. These liabilities could be significant and materially and adversely impact our financial results and liquidity.

*Endangered Species and Bald and Golden Eagle Protection Acts.* The ESA and similar state legislation protect species designated as threatened, endangered or other special status. The U.S. Fish and Wildlife Service (the “USFWS”) works closely with the OSMRE and state regulatory agencies to ensure that species subject to the ESA are protected from mining-related impacts. Several species indigenous to the areas in which we operate are protected under the ESA. Other species in the vicinity of our operations may have their listing status reviewed in the future and could also become protected under the ESA. In addition, the USFWS has identified bald eagle habitats in some of the counties where we operate. The Bald and Golden Eagle Protection Act prohibits taking certain actions that would harm bald or golden eagles without obtaining a permit from the USFWS. Compliance with the requirements of the ESA and the Bald and Golden Eagle Protection Act could have the effect of prohibiting or delaying us from obtaining mining permits. These requirements may also include restrictions on timber harvesting, road building and other mining or agricultural activities in areas containing the affected species or their habitats. There is also increasing interest in nature-related matters beyond protected species, such as general biodiversity, which may similarly require us or our customers to incur costs or take measures which may adversely impact our business or operations.

*Use of Explosives.* Our surface mining operations are subject to numerous regulations relating to blasting activities. Due to these regulations, we will incur costs to design and implement blast schedules and to conduct pre-blast surveys and blast monitoring. In addition, the storage of explosives is subject to various regulatory requirements. For example, the Department of Homeland Security requires facilities in possession of chemicals of interest (including ammonium nitrate at certain threshold levels) to complete a screening review. Our mines are low risk, Tier 4 facilities which are not subject to additional security plans. The adoption of future, more stringent standards related to the use of explosives could materially adversely impact our cost or ability to conduct our mining operations.

*National Environmental Policy Act.* The National Environmental Policy Act (the “NEPA”) requires federal agencies, including the Department of Interior, to evaluate major agency actions that have the potential to significantly impact the environment, such as issuing a permit or other approval. In the course of such evaluations, an agency will typically prepare an environmental assessment to determine the potential direct, indirect and cumulative impacts of a proposed project. Where the activities in question have significant impacts to the environment, the agency must prepare an environmental impact statement. Compliance with the NEPA can be time-consuming and may result in the imposition of mitigation measures that could affect the amount of coal that we are able to produce from mines on federal lands and may require public comment. Furthermore, whether agencies have complied with the NEPA is subject to legal challenge, which can delay or halt projects. The NEPA review process, including potential disputes regarding the level of evaluation required for climate change impacts, may extend the time and/or increase the costs and difficulty of obtaining necessary governmental approvals, and may lead to litigation regarding the adequacy of the NEPA analysis, which could delay or potentially preclude the issuance of approvals or grant of leases.

Since 2020 there have been several legal actions regarding proposals by the Council on Environmental Quality’s (“CEQ”) to revise NEPA’s implementing regulations. Most recently, on January 6, 2026, the CEQ finalized a rule that formally removed its NEPA implementing regulations (40 CFR Parts 1500–1508) from the Code of Federal Regulations, resulting in agencies following their own agency-specific procedures to implement NEPA. Under the OBBBA, project sponsors can also pay to expedite timeframes for environmental assessments and environmental impact statements.

*Other Environmental Laws.* We are required to comply with numerous other federal, state, and local environmental laws and regulations in addition to those previously discussed. These additional laws include but are not limited to the Safe Drinking Water Act, the Toxic Substances Control Act, the Emergency Planning and Community Right-to-Know Act and similar state laws. Each of these laws can impact permitting or planned operations and can result in additional costs or operational delays.

​

Seasonality

Our primary business is not materially impacted by seasonal fluctuations. Demand for metallurgical coal is generally more heavily influenced by other factors such as the general economy, interest rates and commodity prices.

Human Capital Resources

We believe our employees are a competitive advantage. We seek to foster a culture that strives to provide a safe, healthy and rewarding work environment with opportunities for growth. We had approximately 900 employees as of December 31, 2025, including our named executive officers, and nearly all of our employees are full-time employees. None of our employees are covered by collective bargaining agreements, and we have not experienced any strikes or work stoppages related to labor relation issues. We believe we have good relations with our employees. Our human capital resources objectives include, as applicable, identifying, recruiting, training, retaining, incentivizing and integrating our existing and additional employees. We also depend on experienced contractors and third-party consultants to conduct some of our day-to-day activities. We plan to continue to use the services of many of these contractors and consultants.

*Safety Philosophy.* We have a comprehensive health and safety program based on the core belief that all accidents and occupational illnesses are preventable. We believe that:

- Business excellence is achieved through the pursuit of safer and more productive work practices.
- Any task that cannot be performed safely should not be performed.
- Working safely is a requirement of our employees.
- Controlling the work environment is important, but human behavior within the work environment is paramount.
- Safety starts with individual decision-making—all employees must assume a share of responsibility for acts within their control that pose a risk of injury to themselves or fellow workers.
- All levels of the organization must be proactive in implementing safety processes that promote a safe and healthy work environment.
- Consequently, we are committed to providing a safe work environment; providing our employees with proper training and equipment; and implementing safety and health rules, policies and programs that foster safety excellence.

Our safety program includes a focus on the following:

- *Hiring the Right Workers*. Our hiring program includes significant pre-employment screening and reference checks.
- *Safety Incentives*. We have a compensation system that encourages and rewards excellent safety performance.
- *Communication*. We conduct regular safety meetings with the frequent involvement of senior management to reinforce the “tone at the top.”
- *Drug and Alcohol Testing*. We require pre-employment drug screening as well as regular random drug testing that exceeds regulatory requirements.
- *Continuous Improvement Programs*. We track key safety performance metrics, including accident rates, violation types and frequencies. We have specific targets in these areas, and we measure performance against these targets. Specific action plans are implemented for targeted improvement in areas where performance falls below our expectations.
- *Training*. Our training program includes comprehensive new employee orientation and training, annual refresher training and task training components. These training modules are designed to reinforce our high safety expectations. Work rules and procedures are a key element of this training.
- *Accident Investigation*. We have a structured accident investigation procedure that identifies root causes of accidents as well as actions necessary to prevent reoccurrence. We focus on near misses and close calls as a means of attempting to prevent more serious accidents from occurring.
- *Safety Audits*. We conduct periodic safety audits that include workplace examinations, including observation of workers at work, as well as safety program reviews. Both internal and external resources are utilized to conduct these audits.
- *Employee Performance Improvement*. A key element of our safety program is the recognition that safe work practices are a requirement of employment. We identify employee performance that is below expectations and develop specific action plans for improvement.
- *Employee Involvement*. The key to excellent safety is employee involvement and engagement. We foster direct employee involvement in a number of ways including audit participation, accident investigations, as training resources and through solicitation of ideas in small group meetings and through anonymous workplace observation suggestion boxes.
- *Positive Reinforcement*. Establishing safety as a core belief is paramount to our safety performance. As a result, we look for opportunities to celebrate accomplishments and to build pride in our operational safety and performance.

## Item 1A. Risk Factors

Our business involves certain risks and uncertainties. The following is a description of significant risks that might cause our future financial condition or results of operations to differ materially from those expected. In addition to the risks and uncertainties described below, we may face other risks and uncertainties, some of which may be unknown to us and some of which we may deem immaterial. If one or more of these risks or uncertainties occur, our business, financial condition or results of operations may be materially and adversely affected. A summary of our risk factors is as follows:

- Our growth prospects may be adversely affected by fluctuations in demand for, and prices of, rare earth elements and critical minerals.
- We do not currently have rare earth elements or critical mineral reserves, and our growth prospects may be adversely affected if we are unable to successfully develop the Brook Mine into a commercial scale mine.
- An increase in the global supply of rare earth element products, dumping, predatory pricing and other anti-competitive tactics taken by our competitors may materially and adversely affect our growth prospects and the price of our common stock.
- Consolidation of the rare earth elements and critical minerals industry may result in increased competition.
- Certain of our properties have not yet been fully developed into producing coal mines and, if we experience any development delays or cost increases or are unable to complete the construction of our facilities, our business, financial condition and results of operations could be adversely affected.
- We have customer concentration, so the loss of, or significant reduction in, purchases by our largest coal customers could adversely affect our business, financial condition, results of operations and cash flows.
- Our customer base is highly dependent on the steel industry.
- We do not enter into long-term coal sales contracts and as a result we are exposed to fluctuations in market pricing.
- The failure to access coal preparation facilities may have a material adverse effect on our ability to produce coal for our prospective customers and to meet quality specifications.
- We face uncertainties in estimating our economically recoverable coal reserves, and inaccuracies in our estimates could result in lower-than-expected revenues, higher than expected costs and decreased profitability.
- Our inability to acquire additional coal reserves that are economically recoverable may have a material adverse effect on our future profitability.
- The availability and reliability of transportation facilities and fluctuations in transportation costs could affect the demand for our coal or impair our ability to supply coal to prospective customers.
- Any significant downtime of our major pieces of mining equipment, including any preparation plants, could impair our ability to supply coal to prospective customers and materially and adversely affect our results of operations.
- Certain provisions in typical long-term sales contracts provide limited protection during adverse economic conditions, which may eventually result in economic penalties to us or permit the customer to terminate the contract. Furthermore, our ability to collect payments from prospective customers could be impaired if their creditworthiness declines or if they fail to honor their contracts with us.
- To maintain and grow our business, we will be required to make substantial capital expenditures. If we are unable to obtain needed capital or financing on satisfactory terms, we may have to curtail our operations and delay our construction and growth plans, which may materially adversely affect our business, results of operations, financial condition and cash flows, and ability to pay dividends to our stockholders.
- We may not be able to obtain equipment, parts and supplies in a timely manner, in sufficient quantities or at reasonable costs to support our coal mining and transportation operations.
- Our operations could be adversely affected if we are unable to obtain required financial assurance, or if the costs of financial assurance increase materially.
- Defects in title or loss of any leasehold interests in our properties could limit our ability to conduct mining operations on these properties or result in significant unanticipated costs.
- A shortage of skilled labor in the mining industry could pose a risk to achieving improved labor productivity, which could adversely affect our profitability.
- We and our significant stockholders are subject to the Applicant Violator System.
- The enactment of legislative and regulatory measures could adversely affect our mining operations or cost structure or our customers’ ability to use coal, which could have a material adverse effect on our financial condition and results of operations.
- Current and future laws, regulations and other legal requirements relating to protection of the environment and natural resources may increase our costs of doing business and may restrict our coal operations.
- Our operations may impact the environment or cause exposure to hazardous substances, and our properties may have environmental contamination, which could expose us to significant costs and liabilities.
- We must obtain, maintain, and renew governmental permits and approvals for mining operations, which can be a costly and time-consuming process and result in restrictions on our operations.
- Federal or state regulatory agencies have the authority to order certain of our mines to be closed under certain circumstances, which could materially and adversely affect our ability to meet customer demands.
- Our customers are subject to extensive existing and future laws, regulations and other legal requirements relating to protection of the environment, which could negatively impact our business and the market for our products.
- Our mines are subject to stringent federal and state safety regulations that increase our cost of doing business at active operations and may place restrictions on our methods of operation. In addition, government inspectors in certain circumstances may have the ability to order our operations to be shut down based on safety considerations.
- We have reclamation, mine closing, and related environmental obligations under the SMCRA. If the assumptions underlying our accruals are inaccurate, we could be required to expend greater amounts than anticipated.
- Our ability to pay dividends on our Class A common stock and our Class B common stock may be limited by the amount of cash we generate from operations following the payment of fees and expenses, by restrictions in debt instruments and by additional factors unrelated to our profitability.
- Certain of our directors have significant duties with, and spend significant time serving, entities that may compete with us in seeking acquisitions and business opportunities and, accordingly, may have conflicts of interest in allocating time or pursuing business opportunities.
- Holders of Class B common stock are common stockholders of the Company and, therefore, are subject to risks associated with an investment in the Company as a whole, even if the holder does not own Class A common stock.
- Our Board’s ability to reattribute businesses, assets, and expenses between Class A and Class B common stock may make it difficult to assess the future prospects of a class of common stock based on past performance.
- The market price of Class B common stock may not reflect performance of CORE attributed to it, as we intend.
- We may not pay dividends equally or at all on our classes of common stock.
- Our tracking stock capital structure could create conflicts of interest, and our Board may make decisions that could adversely affect only the holders of one class of our common stock.
- The terms of the indentures governing our Senior Notes and the agreements and instruments governing our other indebtedness, including the Credit Agreement, and surety bonding obligations impose restrictions that may limit our operating and financial flexibility.
- We may be able to incur substantially more debt, which could have important consequences to you.
- Our future indebtedness could adversely affect our business, financial condition, results of operations, and ability to meet our payment obligations under the Senior Notes and our other debt.

**Risks Related to Our Business**

Our growth prospects may be adversely affected by fluctuations in demand for, and prices of, rare earth elements and critical minerals.

Changes in the level of demand for, and the market price of (including taxes and other tariffs and fees imposed upon) rare earth elements and critical minerals could significantly affect our growth prospects, which depend in large part on our ability to successfully develop the Brook Mine into a producing mine. As is the case with any mining asset that is not yet in commercial production, there is no assurance that we will be able to successfully develop the Brook Mine into a commercial scale mine. In particular, the prices for rare earth elements and critical minerals may fluctuate and are likely to be affected by numerous factors beyond our control such as interest rates, exchange rates, taxes, inflation, fluctuation in the relative value of the U.S. dollar against foreign currencies, shipping and other transportation and logistics costs, global and regional supply and demand for rare earth minerals and products, potential industry trends and the political and economic conditions of countries that produce and procure rare earth elements and critical minerals. In addition, a future change in the U.S. federal administration could result in changing policies and priorities, including with respect to trade policy and tariffs, taxes and regulation generally, all of which may have a detrimental impact on the demand for rare earth elements and critical minerals and related products.

Furthermore, supply side factors may have a significant influence on price volatility for rare earth elements and critical minerals. Supply of rare earth elements and critical minerals is currently dominated by Chinese producers. The Chinese Central Government regulates production via export bans, quotas and looser environmental standards compared to other countries, and, to a lesser extent, regulation of imports, and has and may continue to change such export bans, production quotas, environmental standards, and import regulations. Over the past few years, there has been significant restructuring of the Chinese market in line with Chinese Central Government policy; however, periods of over-supply or speculative trading of rare earth elements and critical minerals can lead to significant fluctuations in the market price of such products. A prolonged or significant economic contraction in the U.S., China, or worldwide could put downward pressure on market prices of rare earth elements and critical minerals. Protracted periods of low prices for rare earth elements and critical minerals could significantly impact our growth prospects. Demand for rare earth elements and critical minerals may be impacted by demand for downstream products such as hybrid and electric vehicles, wind turbines, robotics, medical equipment, military equipment and other high-growth, advanced motion technologies, as well as demand in the general automotive and electronics industries. By contrast, extended periods of high commodity prices may create economic dislocations that may be destabilizing to rare earth elements and critical minerals supply and demand and ultimately to the broader markets. Strong rare earth elements and critical minerals prices may create economic pressure to identify or create alternate technologies that ultimately could depress long-term demand for rare earth minerals and products, and at the same time may incentivize development of competing mining properties.

Based on all of the above, we cannot provide assurance that mineralization can be mined or processed profitably or that we will be able to successfully commercialize our rare earth elements and critical mineral mining capabilities.

We do not currently have rare earth elements or critical mineral reserves, and our growth prospects may be adversely affected if we are unable to successfully develop the Brook Mine into a commercial scale mine.

As described in the Brook Mine – Technical Report Summary (TRS) for the Brook Mine prepared by Weir (September 17, 2025), our estimates of rare earth elements and critical minerals are reported as in-place inferred resources. Mineral resources are not mineral reserves and do not meet the threshold for reserve modifying factors, such as estimated economic viability, that would allow for conversion to mineral reserves. There is no certainty that any part of the mineral resources estimated will be converted into mineral reserves in the future. Rare earth elements and critical minerals are a new initiative for us and, as such, have required and will continue to require us to make significant investments to build out our rare earth element capabilities. As a new facet of our business, there are heightened risks and uncertainties, and there is no assurance that we will be able to successfully develop the Brook Mine into a commercial scale mine. We have in the past pursued alternative strategies and initiatives outside the scope of our core metallurgical mining business that have not to date resulted in meaningful returns on our investment. We have little to no demonstrated track record of commercial, operational or financial success outside of our core business, and given the

uncertainties associated with rare earth elements and critical minerals and the mining thereof, we cannot assure you that this initiative will be successful.

An increase in the global supply of rare earth element products, dumping, predatory pricing and other anti-competitive tactics taken by our competitors may materially and adversely affect our growth prospects and the price of our common stock.

The pricing of and demand for rare earth element products is affected by a number of factors beyond our control, including the global macroeconomic environment and the global supply and demand for products that use rare earth elements and critical minerals. China accounts for the significant majority of global rare earth element and critical mineral production and also dominates the manufacture of metals from rare earth elements, capabilities that are not currently present at scale in the U.S. Over the past few years, there has been significant restructuring of the Chinese rare earth element production industry, further centralizing control over production by state-owned enterprises. Chinese competitors may engage in predatory pricing or other behaviors designed to inhibit competition. Any increase in the amount of rare earth element products exported from China or other nations and increased competition may adversely affect our ability to develop Brook Mine into an economically feasible producing mine or, in the future, our ability to ultimately profitably recover and sell rare earth elements and critical minerals, which could adversely impact our growth prospects and the price of our common stock. As a result of these factors, we may not be able to compete effectively against current and future competitors.

Chinese competitors may have greater financial resources, as well as other strategic advantages to operate, maintain, improve, and possibly expand their facilities. Additionally, our Chinese competitors have historically been able to produce at relatively low costs due to domestic economic and regulatory factors, including less stringent environmental and governmental regulations and lower labor and benefit costs. If we are not able to achieve consistent product quality at our anticipated costs of production, then any strategic advantages that our competitors may have over us, including, without limitation, lower labor, compliance, and production costs, could have a material adverse effect on our growth prospects and the price of our common stock.

Consolidation of the rare earth elements and critical minerals industry may result in increased competition.

Some of our competitors have made, or may make, acquisitions or enter into partnerships or other strategic relationships to achieve competitive advantages. In addition, new entrants not currently considered competitors may enter our market through acquisitions, partnerships, or strategic relationships. We expect these trends to continue as demand for rare earth element materials increases. Industry consolidation may result in competitors with more compelling product offerings or greater pricing flexibility than we may have, or business practices that make it more difficult for us to compete effectively, including on the basis of price, sales, technology or supply. For example, in December 2021, China merged three state entities to establish the China Rare Earth Group Co. Ltd (“China Rare Earth Group”), that accounts for more than half of China’s heavy rare earths supplies. China Rare Earth Group has enhanced pricing power of key rare earth elements, such as dysprosium and terbium, which has brought changes to the global rare earth elements supply chain. These competitive pressures could have a material adverse effect on our growth prospects and the price of our common stock.

​

Certain of our properties have not yet been fully developed into producing coal mines and, if we experience any development delays or cost increases or are unable to complete the construction of our facilities, our business, financial condition and results of operations could be adversely affected.

We have not completed development plans for all of our coal properties, and do not expect to have full annual production from all of our properties until market conditions permit us to resume and complete these development plans. We expect to incur significant capital expenditures until we have completed the development of our properties. In addition, the development of our properties involves numerous regulatory, environmental, political and legal uncertainties that are beyond our control and that may cause delays in, or increase the costs associated with, their completion. Accordingly, we may not be able to complete the development of the properties on schedule, at the budgeted cost or at all, and any delays beyond the expected development periods or increased costs above those expected to be

incurred could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

If we are unable to complete or are substantially delayed in completing the development of any of our properties, our business, financial condition, results of operations cash flows and ability to pay dividends to our stockholders could be adversely affected.

​

We have customer concentration, so the loss of, or significant reduction in, purchases by our largest coal customers could adversely affect our business, financial condition, results of operations and cash flows.

We are exposed to risks associated with an increasingly concentrated customer base both domestically and globally.

​

There are inherent risks whenever a significant percentage of total revenues are concentrated with a limited number of customers. Revenues from our largest customers may fluctuate from time to time based on numerous factors, including market conditions, which may be outside of our control. If any of our largest customers experience declining revenues due to market, economic or competitive conditions, we could be pressured to reduce the prices that we charge for our coal, which could have an adverse effect on our margins, profitability, cash flows and financial position. If any customers were to significantly reduce their purchases of coal from us, including by failing to buy and pay for coal they committed to purchase in sales contracts, our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders could be adversely affected.

​

See Item 8 of Part II, “Financial Statements and Supplementary Data—Note 2—Summary of Significant Accounting Policies—Concentrations” for additional information.

​

Our customer base is highly dependent on the steel industry.

Substantially all of the metallurgical coal that we produce is sold to steel producers. Therefore, demand for our metallurgical coal is highly correlated to the steel industry. The steel industry’s demand for metallurgical coal is affected by a number of factors including the cyclical nature of that industry’s business, technological developments in the steel-making process and the availability of substitutes for steel such as aluminum, composites and plastics. A significant reduction in the demand for steel products would reduce the demand for metallurgical coal, which would have a material adverse effect on our business, financial condition, cash flows and results of operations. Similarly, if less expensive ingredients could be used in substitution for metallurgical coal in the integrated steel mill process, the demand for metallurgical coal would materially decrease, which would also materially, adversely affect demand for our metallurgical coal. Our export customers include foreign steel producers who may be affected by the tariffs to the extent their production is imported into the U.S. Retaliatory threats by foreign nations to these tariffs may limit international trade and adversely impact global economic conditions.

​

Deterioration in the global economic conditions in any of the industries in which prospective customers operate, a worldwide financial downturn or negative credit market conditions could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

Economic conditions in the industries in which most of our prospective customers operate, such as steelmaking and electric power generation, substantially deteriorated in recent years and reduced the demand for coal. A deterioration of economic conditions in our prospective customers’ industries could cause a decline in demand for and production of metallurgical coal. Renewed or continued weakness in the economic conditions of any of the industries served by prospective customers could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

We do not enter into long-term sales contracts for our coal, and as a result, we are exposed to fluctuations in market pricing.

Sales commitments in the metallurgical coal market are typically not long-term in nature and are generally no longer than one year in duration. Most metallurgical coal transactions in the U.S. are done on a calendar year basis, where both prices and volumes are fixed in the third and fourth quarter for the following calendar year. Globally the market is evolving to shorter term pricing. Some annual contracts have shifted to quarterly contracts and most volumes are being sold on an indexed basis, where prices are determined by averaging the leading spot indexes reported in the market and adjusting for quality. As a result, we are subject to fluctuations in market pricing. We are not protected from oversupply or market conditions where we cannot sell our coal at economic prices. Metallurgical coal has been an extremely volatile commodity over the past ten years and prices are likely to be volatile in the future. There can be no assurances we will be able to mitigate such conditions as they arise. Any sustained failure to be able to market our coal during such periods would have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

The failure to access coal preparation facilities may have a material adverse effect on our ability to produce coal for our prospective customers and to meet quality specifications.

The costs of establishing the infrastructure necessary to enable us to continue to ramp up our mining operations will be significant. We have constructed preparation and loading facilities at our Elk Creek Complex and have recently undertaken expansion projects to increase the rates of processing and preparation. Our Berwind Complex will remain under development until we reach our full targeted annual coal production. Our failure to provide the necessary preparation, processing and loading facilities for our projects would have a material adverse effect on our operations.

​

The risks associated with the construction and operation of mines, processing plants and related infrastructure include:

- the potential lack of availability or cost of skilled and unskilled labor, equipment and principal supplies needed for construction of facilities;
- the need to obtain necessary environmental and other governmental approvals and permits and the timing of the receipt of those approvals and permits;
- industrial accidents;
- geologic mine failures, surface facility construction failures or mining, coal processing or transport equipment failures;
- structural failure of an impoundment or refuse area;
- natural phenomena such as inclement weather conditions, floods, droughts, rockslides and seismic activity;
- unusual or unexpected geological and coal quality conditions;
- potential opposition from non-governmental organizations, environmental groups or other activists, which may delay or prevent development activities; and
- restrictions or regulations imposed by governmental or regulatory authorities.

​

The costs, timing and complexities of developing our projects may be greater than anticipated. Cost estimates may increase significantly as more detailed engineering work is completed on a project. It is common in mining operations to experience unexpected costs, problems and delays during construction, development and mine start-up.

​

Product alternatives or other technologies may reduce demand for our products.

Substantially all of our coal production is comprised of metallurgical coal, which commands a significant price premium over the majority of other forms of coal because of its use in blast furnaces for steel production. Metallurgical coal has specific physical and chemical properties, which are necessary for efficient blast furnace operation. Steel producers are continually investigating alternative steel production technologies with a view to reducing production costs. The steel industry has increased utilization of electric arc furnaces or pulverized coal injection processes, which reduce or eliminate the use of furnace coke, an intermediate product produced from metallurgical coal and, in turn, generally decreases the demand for metallurgical coal. Many alternative technologies are designed to use lower quality

coals or other sources of carbon instead of higher cost high-quality metallurgical coal. While conventional blast furnace technology has been the most economic large-scale steel production technology for a number of years, and emergent technologies typically take many years to commercialize, there can be no assurance that over the longer term competitive technologies not reliant on metallurgical coal would not emerge, which could reduce the demand and price premiums for metallurgical coal.

​

Moreover, we may produce and market other coal products, such as thermal coal, which are also subject to alternative competition. Alternative technologies are continually being investigated and developed in order to reduce production costs or minimize environmental or social impact. In particular, alternatives with lower carbon footprints than our products are currently being researched and developed, as our customers are subject to increasing market and/or regulatory pressure to reduce their impacts on climate change. Further, the development and use of emerging technologies in the generation, transmission, storage and consumption of energy, including renewable energy, battery storage, and energy efficiency technologies, may increase the availability of alternative energy sources or lower demand for coal, resulting in lower prices and revenues. If competitive technologies emerge that use other materials in place of or otherwise eliminate the need for our products, demand and price for our products might fall.

​

We face uncertainties in estimating our economically recoverable coal reserves, and inaccuracies in our estimates could result in lower-than-expected revenues, higher than expected costs and decreased profitability.

Coal is economically recoverable when the price at which coal can be sold exceeds the costs and expenses of mining and selling the coal. Any forecasts of our future performance are based on, among other things, estimates of our recoverable coal reserves. We base our reserve information on geologic data, coal ownership information and current and proposed mine plans. There are numerous uncertainties inherent in estimating quantities and qualities of coal and costs to mine recoverable reserves, including many factors beyond our control. As a result, estimates of economically recoverable coal reserves are by their nature uncertain. Some of the factors and assumptions that can impact economically recoverable coal reserve estimates include:

​

- geologic and mining conditions;
- historical production from the area compared with production from other producing areas;
- the assumed effects of environmental and other regulations and taxes by governmental agencies;
- our ability to obtain, maintain and renew all required permits;
- future improvements in mining technology;
- assumptions related to future prices; and
- future operating costs, including the cost of materials, and capital expenditures.

​

Each of the factors that impact reserve estimation may vary considerably from the assumptions used in estimating the reserves. For these reasons, estimates of coal reserves may vary substantially. Actual production, revenues and expenditures with respect to our future coal reserves may vary from estimates, and these variances may be material. As a result, our estimates may not accurately reflect our actual future coal reserves.

​

Our inability to acquire additional coal reserves that are economically recoverable may have a material adverse effect on our future profitability.

Our profitability depends substantially on our ability to mine, in a cost-effective manner, coal reserves that possess the quality characteristics that prospective customers desire. Because our reserves will decline as we mine our coal, our future profitability depends upon our ability to acquire additional coal reserves that are economically recoverable to replace the reserves we will produce. If we fail to acquire or develop sufficient additional reserves over the long term to replace the reserves depleted by our production, our existing reserves could eventually be exhausted.

​

We are dependent on contractors for the successful completion of the development of our properties.

We regularly use contractors in the development of our mines. Timely and cost-effective completion of the development of our properties, including necessary facilities and infrastructure, in compliance with agreed specifications

is central to our business strategy and is highly dependent on the performance of our contractors under the agreements with them.

​

Although some agreements may provide for liquidated damages, if the contractor fails to perform in the manner required with respect to certain of its obligations, the events that trigger a requirement to pay liquidated damages may delay or impair the operation of our properties, and any liquidated damages that we receive may not be sufficient to cover the damages that we suffer as a result of any such delay or impairment. Further, we may have disagreements with our contractors about different elements of the construction process, which could lead to the assertion of rights and remedies under their contracts and increase the costs associated with development of the properties or result in a contractor’s unwillingness to perform further work. If any contractor is unable or unwilling to perform according to the negotiated terms and timetable of its respective agreement for any reason or terminates its agreement, we would be required to engage a substitute contractor. This would likely result in significant project delays and increased costs, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

Prices for coal are volatile and can fluctuate widely based upon a number of factors beyond our control, including oversupply relative to the demand available for our coal and weather. A substantial or extended decline in the prices we receive for our coal could adversely affect our business, results of operations, financial condition, cash flows and ability to pay dividends to our stockholders.

Our financial results are significantly affected by the prices we receive for our coal and depend, in part, on the margins that we earn on sales of our coal. Our margins will reflect the price we receive for our coal over our cost of producing and transporting our coal. Prices and quantities under U.S. domestic metallurgical coal sales contracts are generally based on expectations of the next year’s coal prices at the time the contract is entered into, renewed, extended or re-opened. Pricing in the global seaborne market is moving towards shorter term pricing models, typically using indexes. The expectation of future prices for coal depends upon many factors beyond our control, including the following:

​

- the market price for coal;
- overall domestic and global economic conditions, including the supply of and demand for domestic and foreign coal, coke and steel;
- the consumption pattern of industrial consumers, electricity generators and residential users;
- weather conditions in our markets that affect the demand for thermal coal or that affect the ability to produce metallurgical coal;
- competition from other coal suppliers;
- technological advances affecting energy consumption;
- the costs, availability and capacity of transportation infrastructure;
- the impact of domestic and foreign governmental laws and regulations, including environmental and climate change regulations and regulations affecting the coal mining industry, and delays in the receipt of, failure to receive, failure to maintain or revocation of necessary governmental permits; and
- increased utilization by the steel industry of electric arc furnaces or pulverized coal injection processes, which reduce or eliminate the use of furnace coke, an intermediate product produced from metallurgical coal, and generally decrease the demand for metallurgical coal.

​

Metallurgical coal is an extremely volatile commodity. There are no assurances that supplies will remain low, that demand will not decrease or that overcapacity may resume, which could cause declines in the prices of and demand for coal, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

​

Changes in the global economic environment, inflation, rising interest rates, recessions or prolonged periods of slow economic growth, and global instability and actual and threatened geopolitical conflict, could have an adverse effect on our industry and business, as well as those of our customers and suppliers.

Overall economic conditions in the U.S. and globally, including adverse factors such as inflation, rising interest rates, supply chain disruptions and the impacts of the war in Ukraine, significantly impact our business. Periods of economic downturn or continued uncertainty could result in difficulty increasing or maintaining our level of sales or profitability and we may experience an adverse effect on our business, results of operations, financial condition and cash flows.

​

Our operations are subject to economic conditions, including credit and capital market conditions, inflation, prevailing interest rates, and political factors, which if changed could negatively affect our results of operations, cash flows and liquidity. Political factors include, but are not limited to, changes to tax laws and regulations resulting in increased income tax liability, increased regulation, such as carbon emissions limitations or trading mechanisms, limitations on exports of energy and raw materials, and trade remedies. Actions taken by the U.S. government could affect our results of operations, cash flows and liquidity.

​

The ongoing war in Ukraine has had a broad range of adverse impacts on global economic conditions, some of which have had and are likely to continue to have adverse impacts on our business, including increased raw material and energy costs, softer customer demand and lower steel prices.

​

Additionally, we are also exposed to risks associated with the business success and creditworthiness of our suppliers and customers. If our customers or suppliers are negatively impacted by a slowdown in economic markets, we may face the reduction, delay or cancellation of customer orders, delays or interruptions of the supply of raw materials, and increased risk of insolvency and other credit related issues of customers or suppliers, which could delay payments from customers, result in increased customer defaults and cause our suppliers to delay filling, or to be unable to fill, our needs at all or on a timely or cost-effective basis. The occurrence of any of these events may adversely affect our business, results of operations, financial condition and cash flows.

​

Increased competition or a loss of our competitive position could adversely affect sales of, or prices for, our coal, which could impair our profitability. In addition, foreign currency fluctuations could adversely affect the competitiveness of our coal abroad.

We compete with other producers primarily on the basis of coal quality, delivered costs to the customer and reliability of supply. We compete primarily with U.S. coal producers and with some Canadian coal producers for sales of metallurgical coal to domestic steel producers and, to a lesser extent, thermal coal to electric power generators. We also compete with both domestic and foreign coal producers for sales of metallurgical coal in international markets. Certain of these coal producers may have greater financial resources and larger reserve bases than we do. We sell coal to the seaborne metallurgical coal market, which is significantly affected by international demand and competition.

​

We cannot assure you that competition from other producers will not adversely affect us in the future. The coal industry has experienced significant consolidation in recent years, including consolidation among some of our major competitors. We cannot assure you that the result of current or further consolidation in the coal industry, or the reorganization through bankruptcy of competitors with large legacy liabilities, will not adversely affect us. A number of our competitors have idled production over the last several years in light of lower metallurgical coal prices. A stabilization or increase in coal prices could encourage existing producers to expand capacity or could encourage new producers to enter the market.

​

In addition, we face competition from foreign producers that sell their coal in the export market. Potential changes to international trade agreements, trade concessions, foreign currency fluctuations or other political and economic arrangements may benefit coal producers operating in countries other than the United States. Additionally, North American steel producers face competition from foreign steel producers, which could adversely impact the financial condition and business of our prospective customers. We cannot assure you that we will be able to compete on the basis of price or other factors with companies that in the future may benefit from favorable foreign trade policies or

other arrangements. Coal is sold internationally in U.S. dollars and, as a result, general economic conditions in foreign markets and changes in foreign currency exchange rates may provide our foreign competitors with a competitive advantage. If our competitors’ currencies decline against the U.S. dollar or against our prospective foreign customers’ local currencies, those competitors may be able to offer lower prices for coal to prospective customers. Furthermore, if the currencies of our prospective overseas customers were to significantly decline in value in comparison to the U.S. dollar, those prospective customers may seek decreased prices for the coal we sell to them. Consequently, currency fluctuations could adversely affect the competitiveness of our coal in international markets, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

​

Our business involves many hazards and operating risks, some of which may not be fully covered by insurance. The occurrence of a significant accident or other event that is not fully insured could adversely affect our business, results of operations, financial condition and cash flows, and ability to pay dividends to our stockholders.

Our mining operations, including our preparation and transportation infrastructure, are subject to many hazards and operating risks. Underground mining and related processing activities present inherent risks of injury to persons and damage to property and equipment. Our mines are subject to a number of operating risks that could disrupt operations, decrease production and increase the cost of mining for varying lengths of time, thereby adversely affecting our operating results. In addition, if coal production declines, we may not be able to produce sufficient amounts of coal to deliver under future sales contracts. Our inability to satisfy contractual obligations could result in prospective customers initiating claims against us. The operating risks that may have a significant impact on our future coal operations include:

​

- variations in thickness of seams of coal;
- adverse geologic conditions, including amounts of rock and other natural materials intruding into the coal seam, that could affect the stability of the roof and the side walls of the mine;
- environmental hazards;
- mining and processing equipment failures, structural failures and unexpected maintenance problems;
- fires or explosions, including as a result of methane, coal, coal dust or other explosive materials, or other accidents;
- unexpected mine accidents, including rock-falls and explosions caused by the ignition of metallurgical coal dust, natural gas or other explosive sources at our mine sites or fires caused by the spontaneous combustion of metallurgical coal or similar mining accidents;
- inclement or hazardous weather conditions and natural disasters or other force majeure events;
- seismic activities, ground failures, rock bursts or structural cave-ins or slides;
- delays in moving our mining equipment;
- railroad delays or derailments;
- security breaches or terroristic acts; and
- other hazards or occurrences that could also result in personal injury and loss of life, pollution and suspension of operations.

​

Any of these risks could adversely affect our ability to conduct operations or result in substantial loss to us as a result of claims for:

​

- personal injury or loss of life;
- damage to and destruction of property, natural resources and equipment, including our coal properties and our coal production or transportation facilities;
- pollution, contamination and other environmental damage to our properties or the properties of others;
- potential legal liability and monetary losses;
- regulatory investigations, actions and penalties;
- suspension of our operations; and
- repair and remediation costs.

​

Although we maintain insurance for a number of risks and hazards, we may not be insured or fully insured, and we may not be able to recover under our insurance policies, against the losses or liabilities that could arise from a significant accident in our future coal operations. We may elect not to obtain insurance for any or all of these risks if we

believe that the cost of available insurance is excessive relative to the risks presented. In addition, pollution, contamination and environmental risks generally are not fully insurable. Moreover, a significant mine accident or regulatory infraction could potentially cause a mine shutdown. For example, on July 10, 2022, we discovered that a material methane ignition at our Berwind mining complex had occurred. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

In addition, if any of the foregoing changes, conditions or events occurs and is not determined to be a force majeure event, any resulting failure on our part to deliver coal to the purchaser under contract could result in economic penalties, suspension or cancellation of shipments or ultimately termination of the agreement, any of which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

Our revenue generating operations are located in a single geographic region, making us vulnerable to risks associated with operating in a single geographic area, including adverse impacts of weaker conditions associated with climate change.

Currently, all of our active revenue generating operations are conducted in a single geographic region in the eastern United States in the Appalachian basin. The geographic concentration of our operations may disproportionately expose us to disruptions in our operations if the region experiences severe weather, transportation capacity constraints, constraints on the availability of required equipment, facilities, personnel or services, significant governmental regulation, natural disasters, pandemics (such as COVID-19) or interruption of transportation or other events that impact the region in which we operate or its surrounding areas. If any of these factors were to impact the region in which we operate more than other coal producing regions, our business, financial condition, results of operations and cash flows will be adversely affected relative to other mining companies that have a more geographically diversified asset portfolio.

​

In addition, weather conditions associated with climate change, such as increased frequency and severity of storms, droughts and floods and other severe weather events, may impact our operations, personnel, physical assets, supply chain, distribution chain, access to raw materials such as water and the cost or availability of insurance. If any such effects were to occur in areas where we or our customers operate, they could have an adverse effect on our business, financial condition and cash flows. Our ability to mitigate the adverse physical impacts of climate change depends in part upon our disaster preparedness and response and business continuity planning.

The availability and reliability of transportation facilities and fluctuations in transportation costs could affect the demand for our coal or impair our ability to supply coal to prospective customers.

Transportation logistics play an important role in allowing us to supply coal to prospective customers. Any significant delays, interruptions, or other limitations on the ability to transport our coal, including those similar to the rail-related constraints we experienced in 2022, could negatively affect our operations. Delays and interruptions of rail services because of accidents, failure to complete construction of rail infrastructure, infrastructure damage, lack of rail or port capacity, weather-related problems, governmental regulation, terrorism, strikes, lockouts, third-party actions or other events could impair our ability to supply coal to customers and adversely affect our profitability. In addition, transportation costs represent a significant portion of the delivered cost of coal and, as a result, the cost of delivery is a critical factor in a customer’s purchasing decision. Increases in transportation costs, including increases resulting from emission control requirements and fluctuations in the price of locomotive diesel fuel and demurrage, could make our coal less competitive, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

Any significant downtime of our major pieces of mining equipment, including any preparation plants, could impair our ability to supply coal to prospective customers and materially and adversely affect our results of operations.

We depend on several major pieces of mining equipment to produce and transport our coal, including, but not limited to, underground continuous mining units and coal conveying systems, surface mining equipment such as highwall miners, front-end loaders and coal overburden haul trucks, preparation plants and related facilities, conveyors

and transloading facilities. If any of these pieces of equipment or facilities suffered major damage or were destroyed by fire, abnormal wear, flooding, incorrect operation or otherwise, we may be unable to replace or repair them in a timely manner or at a reasonable cost, which would impact our ability to produce and transport coal and materially and adversely affect our business, results of operations, financial condition and cash flows. Moreover, the MSHA and other regulatory agencies sometimes make changes with regard to requirements for pieces of equipment. Such changes could cause delays if manufacturers and suppliers are unable to make the required changes in compliance with mandated deadlines.

​

If either our preparation plants, or train loadout facilities, or those of a third party processing or loading our coal, suffer extended downtime, including from major damage, or are destroyed, our ability to process and deliver coal to prospective customers would be materially impacted, which would materially adversely affect our business, results of operations, financial condition, cash flows and ability to pay dividends to our stockholders.

​

If customers do not enter into, extend or honor contracts with us, our profitability could be adversely affected.

Coal mined from our operations is subject to testing by prospective customers for its ability to meet various specifications and to work satisfactorily in their ovens and other facilities prior to entering into contracts for purchase (which are typically short-term orders having terms of one year or less). If we are unable to successfully test our coals or enter into new contracts for the sale of our coal, our ability to achieve profitability would be materially adversely affected. Once we enter into contracts, if a substantial portion of our sales contracts are modified or terminated and we are unable to replace the contracts (or if new contracts are priced at lower levels), our results of operations would be adversely affected, perhaps materially. In addition, if customers refuse to accept shipments of our coal for which they have a contractual obligation, our revenues could be substantially affected and we may have to reduce production at our mines until the customer’s contractual obligations are honored. This, in turn, could have a material adverse effect on the payments we receive which could affect our business, financial condition, cash flows and ability to pay dividends to our stockholders.

​

Certain provisions in typical long-term sales contracts provide limited protection during adverse economic conditions, which may eventually result in economic penalties to us or permit the customer to terminate the contract. Furthermore, our ability to collect payments from prospective customers could be impaired if their creditworthiness declines or if they fail to honor their contracts with us.

We do not expect to enter into significant long-term sales contracts, but if we do, price adjustment, “price reopener” and other similar provisions typical in long-term sales contracts may reduce protection from short-term coal price volatility traditionally provided by such contracts. Price reopener provisions may be included in our future sales contracts. These price reopener provisions may automatically set a new price based on prevailing market price or, in some instances, require the parties to agree on a new price, sometimes within a specified range of prices. Any adjustment or renegotiations leading to a significantly lower contract price could adversely affect our profitability. Some annual metallurgical coal contracts have shifted to quarterly contracts and many include prices determined by averaging the leading spot indexes reported in the market, exposing us further to risks related to pricing volatility.

​

Our ability to receive payment for coal sold and delivered depends on the continued solvency and creditworthiness of prospective customers. The number of domestic steel producers is small, and they compete globally for steel production. If their business or creditworthiness suffers, we may bear an increased risk with respect to payment default. Competition with other coal suppliers could force us to extend credit to customers and on terms that could increase the risk we bear with respect to payment default. We could also enter into agreements to supply coal to energy trading and brokering customers under which a customer sells coal to end-users. If the creditworthiness of any prospective energy trading and brokering customer declines, we may not be able to collect payment for all coal sold and delivered to or on behalf of this customer.

​

In addition, if customers refuse to accept shipments of our coal that they have a contractual obligation to purchase, our revenues will decrease, and we may have to reduce production at our mines until prospective customers’ contractual obligations are honored. Our inability to collect payment from counterparties to our sales contracts may

materially adversely affect our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

We may be unsuccessful in integrating the operations of any future acquisitions, including acquisitions involving new lines of business, with our existing operations, and in realizing all or any part of the anticipated benefits of any such acquisitions.

From time to time, we may evaluate and acquire assets and businesses that we believe complement our existing assets and business, such as the mineral lease with the McDonald Land Company for coal reserves adjacent to our Elk Creek mine complex near Logan, West Virginia. The assets and businesses we acquire may be dissimilar from our initial lines of business. Acquisitions may require substantial capital or the incurrence of substantial indebtedness. Our capitalization and results of operations may change significantly as a result of future acquisitions. We may also add new lines of business to our existing operations.

​

Further, unexpected costs and challenges may arise whenever businesses with different operations or management are combined, and we may experience unanticipated delays in realizing the benefits of an acquisition. Entry into certain lines of business may subject us to new laws and regulations with which we are not familiar and may lead to increased litigation and regulatory risk. Also, following an acquisition, we may discover previously unknown liabilities associated with the acquired business or assets for which we have no recourse under applicable indemnification provisions. If an acquired business or new line of business generates insufficient revenue or if we are unable to efficiently manage our expanded operations, our results of operations may be materially adversely affected.

​

To maintain and grow our business, we will be required to make substantial capital expenditures. If we are unable to obtain needed capital or financing on satisfactory terms, we may have to curtail our operations and delay our construction and growth plans, which may materially adversely affect our business, results of operations, financial condition and cash flows, and ability to pay dividends to our stockholders.

In order to maintain and grow our business, we will need to make substantial capital expenditures associated with our mines and the construction of coal preparation facilities which have not yet been constructed. Constructing, maintaining, repairing and expanding mines and infrastructure, including coal preparation and loading facilities, is capital intensive. Specifically, the exploration, permitting and development of coal reserves, and the maintenance of machinery, equipment and facilities, and compliance with applicable laws and regulations require substantial capital expenditures. While we funded a significant amount of the capital expenditures needed to build out our mining and preparation infrastructure at our Elk Creek property with cash on hand, we must continue to invest capital to maintain or to increase our production and to develop any future acquired properties. Decisions to increase our production levels could also affect our capital needs. We cannot assure you that we will be able to maintain our production levels or generate sufficient cash flow, or that we will have access to sufficient financing to continue our production, exploration, permitting and development activities, and we may be required to defer all or a portion of our capital expenditures.

​

If we do not make sufficient or effective capital expenditures, we will be unable to develop and grow our business. To fund our projected capital expenditures, we will be required to use cash from our operations, incur debt or issue additional common stock or other equity securities. Using cash from our operations will reduce cash available for maintaining or increasing our operating activities and paying dividends to our stockholders. Our ability to obtain bank financing or our ability to access the capital markets for future equity or debt offerings may be limited by our financial condition at the time of any such financing or offering and the covenants in our future debt agreements, as well as by general economic conditions, contingencies and uncertainties that are beyond our control.

​

In addition, incurring debt may significantly increase our interest expense and financial leverage, and issuing additional equity securities may result in significant stockholder dilution.

​

We may not be able to obtain equipment, parts and supplies in a timely manner, in sufficient quantities or at reasonable costs to support our coal mining and transportation operations.

Coal mining consumes large quantities of commodities including steel, copper, rubber products and liquid fuels and requires the use of capital equipment. Some commodities, such as steel, are needed to comply with roof control plans required by regulation. The prices we pay for commodities and capital equipment are strongly impacted by the global market. A rapid or significant increase in the costs of commodities or capital equipment we use in our operations could impact our mining operations costs because we may have a limited ability to negotiate lower prices and, in some cases, may not have a ready substitute.

​

We use equipment in our coal mining and transportation operations such as continuous mining units, conveyors, shuttle cars, rail cars, locomotives, and roof bolters. We procure this equipment from a concentrated group of suppliers, and obtaining this equipment often involves long lead times. Occasionally, demand for such equipment by mining companies can be high and some types of equipment may be in short supply. Delays in receiving or shortages of this equipment, as well as the raw materials used in the manufacturing of supplies and mining equipment, which, in some cases, do not have ready substitutes, or the cancellation of any future supply contracts under which we obtain equipment and other consumables, could limit our ability to obtain these supplies or equipment. In addition, if any of our suppliers experiences an adverse event, or decides to no longer do business with us, we may be unable to obtain sufficient equipment and raw materials in a timely manner or at a reasonable price to allow us to meet our production goals and our revenues may be adversely impacted. We use considerable quantities of steel in the mining process. If the price of steel or other materials increases substantially or if the value of the U.S. dollar declines relative to foreign currencies with respect to certain imported supplies or other products, our operating expenses could increase. Any of the foregoing events could materially and adversely impact our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

We are a holding company, and we depend on the ability of our subsidiaries to distribute funds to us in order to satisfy our financial obligations and to make dividend payments.

We are a holding company, and our subsidiaries conduct all of our operations and own all of our operating assets. We have no significant assets other than the equity interests in our subsidiaries. As a result, our ability to pay our obligations and to make dividend payments depends entirely on our subsidiaries and their ability to distribute funds to us. The ability of a subsidiary to make these distributions could be affected by a claim or other action by a third-party, including a creditor, or by the law of their respective jurisdictions of formation which regulates the payment of dividends. If we are unable to obtain funds from our subsidiaries, we may not be able to declare or pay dividends.

​

Our operations could be adversely affected if we are unable to obtain required financial assurance, or if the costs of financial assurance increase materially.

Federal and state laws require financial assurance to secure our permit obligations including to reclaim lands used for mining, to pay federal and state workers’ compensation and black lung benefits, and to satisfy other miscellaneous obligations. Individually and collectively, revised financial assurance requirements may lead to increased demand for other forms of financial assurance, which may strain capacity for those instruments and increase our costs of obtaining and maintaining the amounts of financial assurance needed for our operations, which may delay the timing for and increase the costs of obtaining this financial assurance.

​

We use surety bonds, trusts and letters of credit to provide financial assurance for certain transactions and business activities. If, in the future, we are unable to secure surety bonds for these obligations and are forced to secure letters of credit indefinitely or obtain some other form of financial assurance at too high of a cost, we may not be able to obtain permits and production on our properties could be adversely affected. This could have a material adverse effect on our business, financial condition, cash flows and ability to pay dividends to our stockholders.

​

Our mines are located in areas containing oil and natural gas operations, which may require us to coordinate our operations with those of oil and natural gas drillers.

Our coal reserves are in areas containing developed or undeveloped oil and natural gas deposits and reservoirs, including the Marcellus Shale in Pennsylvania, and our Virginia reserves are currently the subject of substantial oil and natural gas exploration and production activities, including by horizontal drilling. If we have received a permit for our mining activities, then, while we will have to coordinate our mining with such oil and natural gas drillers, our mining activities are expected to have priority over any oil and natural gas drillers with respect to the land covered by our permit. For reserves outside of our permits, we expect to engage in discussions with drilling companies on potential areas on which they can drill that may have a minimal effect on our mine plan. Depending on priority of interests, our operations may have to avoid existing oil and gas wells or expend sums to plug oil and gas wells.

​

If a well is in the path of our mining for coal on land that has not yet been permitted for our mining activities, we may not be able to mine through the well unless we purchase it. The cost of purchasing a producing horizontal or vertical well could be substantial. Horizontal wells with multiple laterals extending from the well pad may access larger oil and natural gas reserves than a vertical well, which would typically result in a higher cost to acquire. The cost associated with purchasing oil and natural gas wells that are in the path of our coal mining activities may make mining through those wells uneconomical, thereby effectively causing a loss of significant portions of our coal reserves, which could materially and adversely affect our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

Defects in title or loss of any leasehold interests in our properties could limit our ability to conduct mining operations on these properties or result in significant unanticipated costs.

We conduct a significant part of our mining operations on properties that we lease. A title defect or the loss of any lease upon expiration of its term, upon a default or otherwise, could adversely affect our ability to mine the associated reserves and/or process the coal we mine. Title to most of our owned or leased properties and mineral rights is not usually verified until we make a commitment to develop a property, which may not occur until after we have obtained necessary permits and completed exploration of the property. In some cases, we rely on title information or representations and warranties provided by our lessors or grantors. Our right to mine some of our reserves may be adversely affected if defects in title or boundaries exist or if a lease expires. Any challenge to our title or leasehold interests could delay the exploration and development of the property and could ultimately result in the loss of some or all of our interest in the property and, accordingly, require us to reduce our estimated coal reserves. Mining operations from time to time may rely on an expired lease that we are unable to renew. If we were to be in default with respect to leases for properties on which we have mining operations, we may have to close down or significantly alter the sequence of such mining operations, which may adversely affect our future coal production and future revenues. If we mine on property that we do not own or lease, we could incur liability for such mining.

​

In any such case, the investigation and resolution of title issues would divert management’s time from our business and our results of operations could be adversely affected. Additionally, if we lose any leasehold interests relating to any preparation plants, we may need to find an alternative location to process our coal and load it for delivery to customers, which could result in significant unanticipated costs.

​

In order to obtain leases or mining contracts to conduct our mining operations on property where these defects exist, we may in the future have to incur unanticipated costs. In addition, we may not be able to successfully negotiate new leases or mining contracts for properties containing additional reserves or maintain our leasehold interests in properties where we have not commenced mining operations during the term of the lease. Some leases have minimum production requirements. Failure to meet those requirements could result in losses of prepaid royalties and, in some rare cases, could result in a loss of the lease itself.

​

While none of our employees who conduct mining operations are currently members of unions, our business could be adversely affected by union activities.

We are not subject to any collective bargaining or union agreement with respect to properties we currently control. However, it is possible that future employees, or those of our contract miners, who conduct mining operations may join or seek recognition to form a labor union or may be required to become labor agreement signatories. If some or all of the employees who conduct mining operations were to become unionized, it could adversely affect productivity, increase labor costs and increase the risk of work stoppages at our mines. If a work stoppage were to occur, it could interfere with operations and have a material adverse effect on our business, financial condition, results of operations, cash flows and our ability to pay dividends to our stockholders.

​

A shortage of skilled labor in the mining industry could pose a risk to achieving improved labor productivity, which could adversely affect our profitability.

Efficient coal mining using modern techniques and equipment requires skilled laborers, preferably with at least a year of experience and proficiency in multiple mining tasks. The demand for skilled employees sometimes causes a significant constriction of the labor supply resulting in higher labor costs. When met coal producers compete for skilled miners, recruiting challenges can occur and employee turnover rates can increase, which negatively affect operating efficiency and costs. In the event there is a shortage of experienced labor, it could have an adverse impact on our labor productivity and our ability to expand production in the event there is an increase in the demand for our coal.

​

We may face restricted access to international markets in the future.

Access to international markets may be subject to ongoing interruptions and trade barriers due to policies and tariffs of individual countries, and the actions of certain interest groups to restrict the import or export of certain commodities. There can be no assurance that our access to these markets will not be restricted in the future. An inability for U.S. metallurgical coal suppliers to access international markets would likely result in an oversupply of metallurgical coal in the domestic market, resulting in a decrease in prices, which could have a material adverse effect on our business, financial condition, cash flows and ability to pay dividends to our stockholders.

​

We and our significant stockholders are subject to the Applicant Violator System.

Under the SMCRA and its state law counterparts, all coal mining applications must include mandatory “ownership and control” information, which generally includes listing the names of our officers and directors, and our principal stockholders owning 10 percent or more of our voting shares, among others. Ownership and control reporting requirements are designed to allow regulatory review of any entities or persons deemed to have ownership or control of a coal mine, and bars the granting of a coal mining permit to any such entity or person (including any “owner and controller”) who has had a mining permit revoked or suspended, or a bond or similar security forfeited within the five-year period preceding a permit application or application for a permit revision. Regulatory agencies also block the issuance of permits to an applicant who, or whose owner and controller, has permit violations outstanding that have not been timely abated.

​

A federal database, known as the Applicant Violator System, is maintained for this purpose. Certain relationships are presumed to constitute ownership or control, including the following: being an officer or director of an entity; being the operator of the coal mining operation; having the ability to commit the financial or real property assets or working resources of the permittee or operator; based on the instruments of ownership or the voting securities of a corporate entity, owning of record 10% or more of the mining operator, among others. This presumption, in most cases, can be rebutted where the person or entity can demonstrate that it in fact does not or did not have authority directly or indirectly to determine the manner in which the relevant coal mining operation is conducted. An ownership and control notice must be filed by us each time an entity obtains a 10% or greater interest in us. If we have unabated violations of the SMCRA or its state law counterparts, have a coal mining permit suspended or revoked, or forfeit a reclamation bond, we and our “owners and controllers,” as discussed above, may be prohibited from obtaining new coal mining permits, or amendments to existing permits, until such violations of law are corrected. This is known as being “permit-blocked.” Additionally, Yorktown is deemed an “owner or controller” of a number of other mining companies; as such, we could

be permit-blocked based upon the violations of or permit-blocked status of an “owner or controller” of us. This could adversely affect production from our properties.

​

We may be subject to additional limitations on our ability to conduct mining operations due to federal jurisdiction.

We may conduct some underground mining activities on properties that are within the designated boundary of federally protected lands or national forests where the above-mentioned restrictions within the meaning of the SMCRA could apply. Federal court decisions could pose a potential restriction on underground mining within 100 feet of a public road as well as other restrictions. If these SMCRA restrictions ultimately apply to underground mining, considerable uncertainty would exist about the nature and extent of this restriction. While it could remain possible to obtain permits for underground mining operations in these areas even where this 100-foot restriction was applied, the time and expense of that permitting process would be likely to increase significantly, and the restrictions placed on the mining of those properties could adversely affect our costs.

​

Our lessees could satisfy obligations to their customers with minerals from properties other than ours, depriving us of the ability to receive amounts in excess of minimum royalty payments.

​

Mineral supply contracts generally do not require operators to satisfy their obligations to their customers with resources mined from specific locations. Several factors may influence a lessee’s decision to supply its customers with minerals mined from properties we do not own or lease, including the royalty rates under the lessee’s lease with us, mining conditions, mine operating costs, cost and availability of transportation, and customer specifications. In addition, lessees move on and off of our properties over the course of any given year in accordance with their mine plans. If a lessee satisfies its obligations to its customers with minerals from properties we do not own or lease, production on our properties will decrease, and we will receive lower royalty revenues.

​

A lessee may incorrectly report royalty revenues, which might not be identified by our lessee audit process or our mine inspection process or, if identified, might be identified in a subsequent period.

We depend on our lessees to correctly report production and royalty revenues on a monthly basis. Our regular lessee audits and mine inspections may not discover any irregularities in these reports or, if we do discover errors, we might not identify them in the reporting period in which they occurred. Any undiscovered reporting errors could result in a loss of royalty revenues and errors identified in subsequent periods could lead to accounting disputes as well as disputes with our lessees.

​

Because of the unique difficulties and uncertainties inherent in technology development, we face a risk of not being able to capitalize on our license or ownership of intellectual property.

Potential investors should be aware of the difficulties normally encountered by companies developing new technology and the high rate of failure of such enterprises. The likelihood of our successful ability to commercialize intellectual property we own or license must be considered in light of the problems, expenses, difficulties, complications and delays encountered in connection with the development of new technology with limited personnel and financial means. These potential problems include, but are not limited to, unanticipated technical problems that extend the time and cost of product development or unanticipated problems with the operation of the technology.

Technology development involves significant time and expense and can be uncertain.

The development of technology associated with our licensed or owned intellectual property will be costly, complex and time-consuming. Any investment into technology development and commercialization often involves a long wait until a return, if any, is achieved on such investment. We plan to make investments in research and development relating to our owned and licensed intellectual property and technology. Investments in new technology and processes are inherently speculative.

​

Successful technical development of technologies associated with intellectual property does not guarantee successful commercialization.

We may successfully complete the technical development of technologies associated with our owned or licensed intellectual property, but we may still fail to commercialize that technology at scale or at a cost attractive to the target industries. Our success will depend largely on our ability to prove the capabilities and cost-effectiveness of the developed technology. Upon demonstration, the technology may not have the capabilities they were designed to have or that we believed they would have, or they may be more expensive than anticipated. Furthermore, even if we do successfully demonstrate the technology’s capabilities, potential customers may be more comfortable doing business with a larger, more established, more proven company than us. Moreover, competing technologies may prevent us from gaining wide market acceptance of the technology. Significant revenue from new technology investments may not be achieved for a number of years, if at all.

If we fail to protect our intellectual property rights, we could lose our ability to compete in the market.

Our intellectual property and proprietary rights are important to our ability to remain competitive and for the success of our products and our business. Our intellectual property rights may be challenged, invalidated or circumvented by third parties. We may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade secrets by employees or competitors. Furthermore, our competitors may independently develop technologies and products that are substantially equivalent or superior to our technologies and/or products, which could result in decreased revenues. Moreover, the laws of foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. Litigation may be necessary to enforce our intellectual property rights which could result in substantial costs to us and substantial diversion of management attention. If we do not adequately protect our intellectual property, our competitors could use it to enhance their products. Our inability to adequately protect our intellectual property rights could adversely affect our business and financial condition, and the value of our brand and other intangible assets.

Other companies may claim that we infringe their intellectual property, which could materially increase our costs and harm our ability to generate future revenue and profit.

We do not believe that we infringe the proprietary rights of any third party, but claims of infringement are becoming increasingly common, and third parties may assert infringement claims against us. It may be difficult or impossible to identify, prior to receipt of notice from a third party, the trade secrets, patent position or other intellectual property rights of a third party, either in the United States or in foreign jurisdictions. Any such assertion may result in litigation or may require us to obtain a license for the intellectual property rights of third parties. If we are required to obtain licenses to use any third-party technology, we would have to pay royalties, which may significantly reduce any profit on our products. In addition, any such litigation could be expensive and disruptive to our ability to generate revenue or enter into new market opportunities. If any of our products were found to infringe other parties’ proprietary rights and we are unable to come to terms regarding a license with such parties, we may be forced to modify our products to make them non-infringing or to cease production of such products altogether.

​

**Risks Related to Environmental, Health, Safety and Other Regulations**

The enactment of legislative and regulatory measures could adversely affect our mining operations or cost structure or our customers’ ability to use coal, which could have a material adverse effect on our financial condition and results of operations.

At the international level, the United States’ position on the Paris Agreement has shifted repeatedly, creating policy uncertainty with direct implications. The U.S. joined the Paris framework in 2016, withdrew in 2020, reentered in early 2021, and began another withdrawal in 2025 that was finalized on January 27, 2026. The U.S. also participated in various U.N. Framework Conventions on Climate Change and made various other environmental commitments. Various state and local governments also publicly committed to furthering the goals of the Paris Agreement.

​

In federal legislation, the 2021 infrastructure law funded climate resilience and clean energy/transportation investments, though certain climate-focused elements were subsequently curtailed by the 2025 One Big Beautiful Bill Act.

​

In August 2022, President Biden signed the Inflation Reduction Act of 2022 into law. The Inflation Reduction Act provides significant funding and incentives for research and development of low-carbon energy production methods, carbon capture, and other programs directed at addressing climate change. The Biden administration moved to unwind several regulatory rollbacks enacted or proposed by the first Trump administration, including, among others, the ACE Rule, the NWPR, and the proposed NEPA overhaul. In January 2022, the EPA announced coal combustion residuals rules reiterating that surface impoundments cannot be closed with coal ash in contact with groundwater and establishing a federal permitting scheme for the disposal of coal ash and establishing regulations for legacy coal ash surface impoundments and certain other non-impoundment CCR units. The second Trump administration has, in some instances, proposed and in others finalized efforts to reinstate prior rollbacks and pursue additional repeals and restrictions across these regimes. The full extent and timing of such changes is unknown, and future administrations may again reverse policies or changes adopted by the second Trump administration.

​

New, more stringent legislation or regulations related to the protection of the environment, health and safety or the reduction of greenhouse gas emissions, as well as changes in the interpretation and enforcement of such laws and regulations, may require us or our customers to change operations significantly or incur increased costs, which may adversely affect our mining operations, cost structure or our customers’ ability to use coal. Such changes could have a material adverse effect on our financial condition and results of operations.

​

Laws and regulations restricting or encouraging the reduction of greenhouse gas emissions as well as uncertainty concerning such regulations and increasing public attention toward climate change could adversely impact the market for coal, increase our operating costs, and reduce the value of our coal assets and our stock price.

Climate change continues to attract considerable public and scientific attention. There is widespread concern about the contributions of human activity to such changes, especially through the emission of GHGs. Numerous reports, such as the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, have further raised concern about the impacts of fossil fuel combustion on global climate issues. There are three primary sources of GHGs associated with the coal industry. First, the end use of our coal by our customers in electricity generation, coke plants, and steelmaking is a source of GHGs. Second, combustion of fuel by equipment used in coal production and to transport our coal to our customers is a source of GHGs. Third, coal mining itself can release methane, which is considered to be a more potent GHG than carbon dioxide, directly into the atmosphere. These emissions from coal consumption, transportation and production are subject to pending and proposed regulation as part of initiatives to address global climate change.

​

As a result, numerous proposals have been adopted, made and are likely to continue to be made at the international, national, regional, state and local levels of government to monitor and limit emissions of GHGs, including alternative energy requirements, measures promoting renewable energy development, and energy conservation and emissions reductions measures, among others. Collectively, these initiatives could result in higher electricity costs to our customers or lower the demand for coal used in electric or steel generation, which could in turn adversely impact our business. Such initiatives, as well as increasing public attention to climate change more generally, could also result in direct regulation of the GHGs produced by our operations or increase the potential for governmental investigations or litigation. See “Business—Environmental, Health and Safety and Other Regulatory Matters—Global Climate Change.”

​

At present, we are principally focused on metallurgical coal production, which is not used in connection with the production of power generation. However, we may seek to sell greater amounts of our coal into the power-generation market in the future. The market for our coal may be adversely impacted if comprehensive legislation or regulations focusing on GHG emission reductions are adopted, or if our customers are unable to obtain financing for their operations. The extent of future regulation of GHG emissions may inhibit utilities from investing in the building of new coal-fired plants to replace older plants or investing in the upgrading of existing coal-fired plants. Any reduction in the amount of coal consumed by electric power generators as a result of actual or potential regulation of GHG emissions, including any reductions resulting from power plants ceasing operations or switching to fuels that produce fewer GHG

emissions, could decrease demand for our coal, thereby reducing our revenues and materially and adversely affecting our business and results of operations. We or prospective customers may also have to invest in carbon dioxide capture and storage technologies in order to burn coal and comply with future GHG emission standards, and new legislation, regulations or international agreements in the future could otherwise result in increased costs to operate and maintain our or our customers’ facilities, capital expenditures to install other emission controls at our or our customers’ facilities, and costs to administer and manage any potential climate-related reporting or greenhouse gas emissions trading or tax programs. These costs and capital expenditures could be material and could increase the cost of and reduce demand for our products. Relatedly, to the extent others use or develop new technological advances in coal production in response to market or regulatory pressures to reduce their impact on the environment, we may be placed at a competitive disadvantage or may be forced by competitive pressures to implement new technologies at substantial costs. We may not be able to respond to these competitive pressures or implement new technologies on a timely basis or at an acceptable cost. If one or more of the technologies we use now or in the future were to become obsolete, our business, financial condition or results of operations could be materially and adversely affected. See also the risk factor “—Product alternatives or other technologies may reduce demand for our products.”

​

Current and future laws, regulations and other legal requirements relating to protection of the environment and natural resources may increase our costs of doing business and may restrict our coal operations.

We and our potential customers are subject to stringent and complex laws, regulations and other legal requirements enacted by federal, state and local authorities relating to occupational health and safety and protection of the environment and natural resources. These include those legal requirements that govern discharges or emissions of materials into the environment, the management and disposal of substances and wastes, including hazardous wastes, the cleanup of contaminated sites, threatened and endangered plant and wildlife protection, reclamation and restoration of mining properties after mining is completed, mitigation and restoration of streams or other waters, the protection of drinking water, assessment of the environmental impacts of mining, monitoring and reporting requirements, the installation of various safety equipment in our mines, remediation of impacts of surface subsidence from underground mining, and work practices related to employee health and safety. See “Business—Environmental, Health and Safety and Other Regulatory Matters.” Examples include laws and regulations relating to:

​

- occupational health and safety;
- emissions to air and discharges to water;
- plant and wildlife protection, including endangered species protections;
- the reclamation and restoration of properties after mining or other activity has been completed;
- limitations on land use;
- mine permitting and licensing requirements;
- the storage, treatment and disposal of wastes;
- air quality standards;
- water pollution;
- protection of human health, plant life and wildlife, including endangered and threatened species, and biodiversity;
- protection of wetlands;
- the discharge of materials into the environment;
- remediation of contaminated soil, surface and groundwater; and
- the effects of operations on surface water and groundwater quality and availability.

​

Complying with these environmental and employee health and safety requirements, including the terms of our permits, has had, and will continue to have, a significant effect on our costs of operations. In addition, there is the possibility that we could incur substantial costs as a result of violations of environmental laws, judicial interpretations of or rulings on environmental laws or permits, or in connection with the investigation and remediation of environmental contamination. Any additional laws, regulations and other legal requirements enacted or adopted by federal, state and local authorities, or new interpretations of existing legal requirements by regulatory bodies relating to the protection of the environment, including, for example, those related to discharges of selenium, could further affect our costs or limit our operations. See “Business—Environmental, Health and Safety and Other Regulatory Matters.”

​

Our operations may impact the environment or cause exposure to hazardous substances, and our properties may have environmental contamination, which could expose us to significant costs and liabilities.

Our operations currently use hazardous materials and generate limited quantities of hazardous wastes from time to time. Drainage flowing from or caused by mining activities can be acidic with elevated levels of dissolved metals, a condition referred to as “acid mine drainage,” or may include other pollutants requiring treatment. We could become subject to claims for toxic torts, natural resource damages and other damages as well as for the investigation and clean-up of soil, surface water, groundwater, and other media. Such claims may arise, for example, out of conditions at sites that we currently own or operate, as well as at sites that we previously owned or operated, or may acquire. Our liability for such claims may be joint and several, so that we may be held responsible for more than our share of the contamination or other damages, or for the entire share.

​

We maintain coal refuse areas and slurry impoundments as necessary. Such areas and impoundments are subject to extensive regulation. Structural failure of a slurry impoundment or coal refuse area could result in extensive damage to the environment and natural resources, such as bodies of water that the coal slurry reaches, as well as liability for related personal injuries and property damages, and injuries to wildlife. If an impoundment were to fail, we could be subject to claims for the resulting environmental contamination and associated liability, as well as for fines and penalties. Our coal refuse areas and slurry impoundments are designed, constructed, and inspected by our company and by regulatory authorities according to stringent environmental and safety standards.

​

We must obtain, maintain, and renew governmental permits and approvals for mining operations, which can be a costly and time-consuming process and result in restrictions on our operations.

Numerous governmental permits and approvals are required for mining operations. Our operations are principally regulated under permits issued pursuant to the SMCRA and the federal CWA. State and federal regulatory authorities exercise considerable discretion in the timing and scope of permit issuance. Requirements imposed by these authorities may be costly and time-consuming and may result in delays in the commencement or continuation of exploration or production operations. In addition, we may be required to prepare and present to permitting or other regulatory authorities data pertaining to the effect or impact that proposed exploration for or production of coal might have on the environment.

​

Our coal production is dependent upon our ability to obtain various federal and state permits and approvals to mine our coal reserves. The permitting rules, and the interpretations of these rules, are complex, change frequently, and are often subject to discretionary interpretations by regulators, all of which may make compliance more difficult or impractical, and which may possibly preclude the continuance of ongoing mine development or operations or the development of future mining operations. The pace with which the government issues permits needed for new operations and for ongoing operations to continue mining, particularly CWA permits, can be time-consuming and subject to delays and denials. These delays or denials of environmental permits needed for mining could reduce our production and materially, adversely impact our cash flow and results of operations.

​

Prior to discharging any pollutants to waters of the United States, coal mining companies must obtain an NPDES permit from the appropriate state or federal permitting authority. NPDES permits include effluent limitations for discharged pollutants and other terms and conditions, including required monitoring of discharges. Changes and proposed changes in state and federally recommended water quality standards may result in the issuance or modification of permits with new or more stringent effluent limits or terms and conditions. See “Business—Environmental, Health and Safety and Other Regulatory Matters—Clean Water Act.”

​

Further, the public has certain statutory rights to comment on and submit objections to requested permits and environmental impact statements prepared in connection with applicable regulatory processes, and otherwise engage in the permitting process, including bringing citizens’ claims to challenge the issuance or renewal of permits, the validity of environmental impact statements or performance of mining activities. As a result of challenges like these, the permits we need may not be issued or renewed in a timely fashion or issued or renewed at all, or permits issued or renewed may not be maintained, may be challenged or may be conditioned in a manner that may restrict our ability to efficiently and

economically conduct our mining activities, any of which would materially reduce our production, cash flow, and profitability.

​

Permitting rules may also require, under certain circumstances, that we obtain surface-owner consent if the surface estate has been severed from the mineral estate. This could require us to negotiate with third parties for surface access that overlies coal we acquired or intend to acquire. These negotiations can be costly and time-consuming, lasting years in some instances, which can create additional delays in the permitting process. If we cannot successfully negotiate for land access, we could be denied a permit to mine coal we already own.

​

Federal or state regulatory agencies have the authority to order certain of our mines to be temporarily or permanently closed under certain circumstances, which could materially and adversely affect our ability to meet our customers’ demands.

Federal or state regulatory agencies have the authority, under certain circumstances following significant health and safety incidents, such as fatalities, to order a mine to be temporarily or permanently closed. If this occurred, we may be required to incur capital expenditures to re-open the mine. In the event that these agencies order the closing of our mines, our coal sales contracts generally permit us to issue force majeure notices which suspend our obligations to deliver coal under these contracts. However, our customers may challenge our issuances of force majeure notices. If these challenges are successful, we may have to purchase coal from third-party sources, if it is available, to fulfill these obligations, incur capital expenditures to re-open the mines and/or negotiate settlements with the customers, which may include price reductions, the reduction of commitments, the extension of time for delivery or the termination of customers’ contracts. Any of these actions could have a material adverse effect on our business and results of operations.

​

Our customers are subject to extensive existing and future laws, regulations and other legal requirements relating to protection of the environment, which could negatively impact our business and the market for our products.

Coal contains impurities, including sulfur, mercury, chlorine and other elements or compounds, many of which are released into the air when coal is burned. Complying with regulations to address these emissions can be costly for our customers. For example, in order to meet the CAA limits for sulfur dioxide emissions from electric power plants, coal users must install costly pollution control devices, use sulfur dioxide emission allowances (some of which they may purchase), or switch to other fuels. More costly and stringent environmental regulations could adversely impact the operations of our customers, which could in turn adversely impact our business. A number of coal-fired power plants, particularly smaller and older plants, have already been retired or announced that they will retire rather than retrofit to meet the obligations of these and other rules.

​

In addition, considerable uncertainty is associated with new air emissions initiatives that may require significant emissions control expenditures for many coal-fired power plants. As a result, some of our prospective customers may switch to other fuels that generate fewer of these emissions or may install more effective pollution control equipment that reduces the need for low-sulfur coal. Any further switching of fuel sources away from coal, closure of existing coal-fired power plants, or reduced construction of new coal-fired power plants could have a material adverse effect on demand for, and prices received for, our coal. In addition, our coke plant and steelmaking customers may face increased operational costs as a result of higher electric costs. See “Business—Environmental, Health and Safety and Other Regulatory Matters.”

​

Apart from actual and potential regulation of air emissions and solid wastes from coal-fired plants, governmental mandates for increased use of electricity from renewable energy sources could have an impact on the market for our coal. Many states, including Pennsylvania and Virginia, have enacted legislative mandates requiring electricity suppliers to use renewable energy sources to generate a certain percentage of power. Possible advances in technologies and incentives, such as under the Inflation Reduction Act of 2022, to enhance the economics of renewable energy sources could make these sources more competitive with coal. Any reductions in the amount of coal consumed by electric power generators as a result of current or new standards for the emission of impurities, or current or new incentives to switch to renewable fuels or renewable energy sources could reduce the demand for our coal, thereby reducing our revenues and adversely affecting our business, cash flows, results of operations and our ability to pay dividends to our stockholders.

​

Negative sentiment with regard to our business or our industry as well as activism, consumer preferences, and initiatives aimed at limiting climate change or a reduction of air pollutants could interfere with our business activities, operations and ability to access capital sources, result in reduced demand for our products, and negatively impact our stock price.

Public perception of our industry’s contribution to climate change or detractions from the transition to a lower-carbon economy has generated negative sentiment toward our industry and could result in reputational harm to our business, lower demand for our products, and increased demand for alternatives to our products. Numerous activist groups are devoting resources to anti-coal activities to minimize or eliminate the production of or use of coal as a source of electricity generation, domestically and internationally. Participants in the coal mining industry are frequently targeted by activist groups that openly attempt to disrupt the industry. For example, Greenpeace International filed a letter with the SEC alleging that one coal mining company’s filings relating to a proposed public offering of securities may contain incomplete and misleading disclosures regarding the risks of investing in the coal market. On another occasion, the Sierra Club sent a letter to the SEC stating that it believed a coal mining company may be giving potential investors false impressions regarding risks to its business. Other groups have objected to our RAM No. 1 mine permit application in Pennsylvania. It is possible that we could continue to be the target of similar actions in the future, including when we attempt to grow our business through acquisitions or commence new mining operations. Activist groups have also brought lawsuits challenging the issuance of individual coal leases, historical and pending regulatory approvals, permits and processes that are necessary to conduct coal mining operations or to operate coal-fueled power plants. Negative public perception could cause the permits we require to conduct our operations to be withheld, delayed or burdened by requirements that restrict our ability to profitably conduct our business. Litigation risks are also increasing, as a number of government entities and private individuals have sought to bring suit against fossil fuel companies, alleging, among other things, that such companies created public nuisances by producing fuels that contributed to climate change or alleging that the companies have been aware of the adverse effects of climate change for some time but failed to adequately disclose such impacts to their investors or customers. Private individuals or public entities may also seek to enforce laws and regulations against us and could allege personal injury, property damages or other liabilities in relation to climate change or other environmental, social and governance (“ESG”) matters. An unfavorable ruling in any such case could have an adverse impact on our financial condition. Any such activism could therefore materially and adversely impact our ability to operate our business or raise capital.

​

In addition, there have also been efforts in recent years to influence the investment community, including investment advisors, sovereign wealth funds, public pension funds, universities and other groups, promoting the divestment of fossil fuel equities; encouraging the consideration of ESG practices and ESG ratings of companies in a manner that may negatively affect coal companies, including increased negative investor sentiment, divestment of securities issued by coal companies and the diversion of investment to other industries; and also pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel reserves. For example, certain financial institutions, including banks and insurance companies, have taken actions to limit available financing, insurance and other services to entities that produce or use fossil fuels. Several large investment banks have adopted climate change guidelines for lenders. The guidelines require the evaluation of carbon risks in the financing of electric power generation plants, which may make it more difficult for utilities to obtain financing for coal-fired plants. The impact of such efforts and developments may adversely affect the demand for and price of securities issued by us, adversely impact our access to the capital and financial markets, increase the cost of borrowing, cause a decline in our credit rating, increase the cost or reduce the availability of third-party insurance, increase our retention of risk through self-insurance, and limit our flexibility and ability to conduct business development activities. Further, in California, legislation was signed into law in September 2015 to require the state’s pension funds to divest investments in companies that generate 50% or more of their revenue from coal mining by July 2017. Additionally, Maine passed a law in June 2021 requiring the state pension system to divest holdings in coal, petroleum, natural gas and related products by 2026, and the New York State Common Retirement Fund has and is continuing to divest from coal assets. These efforts and developments, as well as concerted conservation and efficiency efforts, could also cause coal prices and sales of our coal to materially decline and could cause our costs to increase.

​

Other activist campaigns have urged companies to cease financing coal-driven businesses. A number of investors and asset managers have enacted such policies as a result, including by beginning to exit investments that

present high sustainability-related risks, such as thermal coal producers. The impact of such efforts may adversely affect the demand for and price of securities issued by us and impact our access to the capital and financial markets. In addition, several well-funded non-governmental organizations have explicitly undertaken campaigns to minimize or eliminate mining and the use of coal as a source of electricity generation. The net effect of these developments is to make it more costly and difficult to maintain our business and to continue to depress the market for coal.

​

Our mines are subject to stringent federal and state safety regulations that increase our cost of doing business at active operations and may place restrictions on our methods of operation. In addition, government inspectors in certain circumstances may have the ability to order our operations to be shut down based on safety considerations.

The MINE Act and MINER Act, and regulations issued under these federal statutes, impose stringent health and safety standards on mining operations. The regulations that have been adopted under the MINE Act and the MINER Act are comprehensive and affect numerous aspects of mining operations, including training of mine personnel, mining procedures, roof control, ventilation, blasting, use and maintenance of mining equipment, dust and noise control, communications, emergency response procedures, and other matters. MSHA regularly inspects mines to ensure compliance with regulations promulgated under the MINE Act and MINER Act. In addition, Pennsylvania, West Virginia, Virginia and Wyoming all have similar programs for mine safety and health regulation and enforcement.

​

The various requirements mandated by federal and state statutes, rules, and regulations may place restrictions on our methods of operation and potentially result in fees and civil penalties for violations of such requirements or criminal liability for the knowing violation of such standards, significantly impacting operating costs and productivity. In addition, government inspectors have the authority to issue orders to shut down our operations based on safety considerations under certain circumstances, such as imminent dangers, accidents, failures to abate violations, and unwarrantable failures to comply with mandatory safety standards. See “Business—Environmental, Health and Safety and Other Regulatory Matters—Mine Safety and Health.”

​

The regulations enacted under the MINE Act and MINER Act, as well as under similar state acts are routinely expanded, raising compliance costs and increasing potential liability. These existing and other future mine safety rules could potentially result in or require significant expenditures, as well as additional safety training and planning, enhanced safety equipment, more frequent mine inspections, stricter enforcement practices and enhanced reporting requirements. At this time, it is not possible to predict the full effect that new or proposed statutes, regulations and policies will have on our operating costs, but any expansion of existing regulations, or making such regulations more stringent may have a negative impact on the profitability of our operations. If we were to be found in violation of mine safety and health regulations, we could face penalties or restrictions that may materially and adversely impact our operations, financial results and liquidity.

​

We must also compensate employees for work-related injuries. State workers’ compensation acts typically provide for an exception to an employer’s immunity from civil lawsuits for workplace injuries in the case of intentional torts. In such situations, an injured worker would be able to bring suit against his or her employer for damages in excess of workers’ compensation benefits. In addition, West Virginia’s workers’ compensation act provides a much broader exception to workers’ compensation immunity, allowing an injured employee to recover against his or her employer if he or she can show damages caused by an unsafe working condition of which the employer was aware and that was a violation of a statute, regulation, rule or consensus industry standard. These types of lawsuits are not uncommon and could have a significant effect on our operating costs.

​

We have obtained from a third-party insurer a workers’ compensation insurance policy, which includes coverage for medical and disability benefits for black lung disease under the Federal Coal Mine Health and Safety Act of 1969 and the MINE Act. We perform periodic evaluations of our black lung liability, using assumptions regarding rates of successful claims, discount factors, benefit increases and mortality rates, among others. Of note, the Patient Protection and Affordable Care Act of 2010 significantly amended the black lung provisions of the MINE Act by reenacting two provisions, which had been eliminated in 1981. Under the amendments, a miner with at least fifteen years of underground coal mine employment (or surface mine employment with similar dust exposure) who can prove that he suffers from a totally disabling respiratory condition is entitled to a rebuttable presumption that his disability is caused by black lung. The other amendment provides that the surviving spouse of a miner who was collecting federal black lung

benefits at the time of his death is entitled to a continuation of those benefits. These changes could have a material impact on our costs expended in association with the federal black lung program.

​

We have reclamation, mine closing, and related environmental obligations under the SMCRA. If the assumptions underlying our accruals are inaccurate, we could be required to expend greater amounts than anticipated.

The SMCRA establishes operational, reclamation and closure standards for our mining operations. The SMCRA requires that comprehensive environmental protection and reclamation standards be met during the course of and following completion of mining activities. Permits for all mining operations must be obtained from the OSMRE or, where state regulatory agencies have adopted federally approved state programs under the SMCRA, the appropriate state regulatory authority. Our operations are located in states which have achieved primary jurisdiction for enforcement of the SMCRA through approved state programs. See “Business—Environmental, Health and Safety and Other Regulatory Matters.”

​

In addition, the SMCRA imposes a reclamation fee on all current mining operations, the proceeds of which are deposited in the AML Fund, which is used to restore unreclaimed and abandoned mine lands mined before 1977. The current per ton fee is $0.224 per ton for surface mined coal and $0.096 per ton for underground mined coal. These fees are currently scheduled to be in effect until September 30, 2034, and on November 15, 2021, the Infrastructure Investment and Jobs Act (“IIJA”), which included the Abandoned Mine Land Reclamation Amendments of 2021, extended OSMRE’s statutory authority to collect reclamation fees for an additional 13 years and to reduce the fee rates.

​

We accrue for the costs of current mine disturbance and of final mine closure, including the cost of treating mine water discharge where necessary. The amounts recorded are dependent upon a number of variables, including the estimated future closure costs, estimated proven reserves, assumptions involving profit margins, inflation rates, and the assumed credit-adjusted risk-free interest rates. If these accruals are insufficient or our liability in a particular year is greater than currently anticipated, our future operating results could be adversely affected. We are also required to post bonds for the cost of a coal mine as a condition of our mining activities.

​

**Risks Related to Our Company**

Our ability to pay dividends on our Class A common stock and our Class B common stock may be limited by the amount of cash we generate from operations following the payment of fees and expenses, by restrictions in debt instruments and by additional factors unrelated to our profitability.

We have paid quarterly dividends at various times in the past and may pay additional special and regular quarterly dividends in the future. Our ability to pay dividends is subject to the discretion of our board of directors and the requirements of applicable law. The timing and amount of dividends declared will depend on, among other things: (a) our earnings, earnings outlook, financial condition, production, processing and shipping levels, cash flow, cash requirements and our outlook on current and future market conditions, (b) our liquidity, including our ability to obtain debt and equity financing on acceptable terms, (c) restrictive covenants in our Credit and Security Agreement (the “Credit Agreement”) with KeyBank National Association, as the administrative agent, and other lenders party thereto, and any future debt instruments and (d) provisions of applicable law governing the payment of dividends.

​

The metallurgical coal industry is highly volatile, and we cannot predict with certainty the amount of cash, if any, that will be available for distribution as dividends in any period. Also, there may be a high degree of variability from period to period in the amount of cash, if any, that is available for the payment of dividends. The amount of cash we generate from operations and the actual amount of cash we will have available for dividends will vary based upon, among other things:

​

- risks related to the impact of pandemics such as the COVID-19 global pandemic, including with regard to the scope and duration of the outbreak, the health and safety of our employees, government actions and restrictive measures implemented in response, delays and cancellations of customer sales, supply chain disruptions and other impacts to the business, or our ability to execute our business continuity plans;
- the development of our properties into producing coal mines;
- the ability to begin generating significant revenues and operating cash flows;
- the market price for coal;
- overall domestic and global economic conditions, including the supply of and demand for domestic and foreign coal, coke and steel;
- unexpected operational events or geological conditions;
- cost overruns;
- our ability to enter into agreements governing the sale of coal, which are generally short-term in nature and subject to fluctuations in market pricing;
- the level of our operating costs;
- prevailing global and regional economic and political conditions;
- changes in interest rates;
- the impact of domestic and foreign governmental laws and regulations, including environmental and climate change regulations and regulations affecting the coal mining industry;
- delays in the receipt of, failure to receive, failure to maintain or revocation of necessary governmental permits;
- modification or revocation of our dividend policy by our board of directors; and
- the amount of any cash reserves established by our board of directors.

​

The amount of cash we generate from our operations may differ materially from our net income or loss for the period, which will be affected by non-cash items. We may incur other expenses or liabilities that could reduce or eliminate the cash available for distribution as dividends.

​

In addition, financing agreements may prohibit the payment of dividends if an event of default has occurred and is continuing or would occur as a result of the payment of such dividends.

​

In addition, Section 170 of the Delaware General Corporation Law (the “DGCL”) allows our board of directors to declare and pay dividends on the shares of our Class A common stock and Class B common stock either (a) out of our surplus, as defined in and computed in accordance with the DGCL or (b) in case there shall be no such surplus, out of our net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. We may not have sufficient surplus or net profits in the future to pay dividends, and our subsidiaries may not have sufficient funds, surplus or net profits to make distributions to us. As a result of these and the other factors mentioned above, we can give no assurance that dividends will be paid in the future.

​

Your percentage of ownership in us may be diluted in the future.

Your percentage of ownership in us may be diluted because of equity issuances for acquisitions, capital market transactions or otherwise, including, without limitation, equity awards that we may be granting to our directors, officers and employees, the conversion of our 2031 Convertible Senior Notes into Class A common stock, and the conversion of our Class B common stock into Class A common stock. Such issuances may have a dilutive effect on our earnings per share, which could adversely affect the market price of our Class A common stock and Class B common stock.

​

It is anticipated that the compensation committee of the board of directors of the Company will grant additional equity awards to Company employees and directors, from time to time, under the Company’s compensation and employee benefit plans. These additional awards will have a dilutive effect on the Company’s earnings per share, which could adversely affect the market price of the Company’s Class A common stock and Class B common stock.

​

The issuance of shares of our Class A common stock upon conversion of the 2031 Convertible Senior Notes will dilute the ownership interests of our stockholders and have a dilutive effect on the Company’s earnings per share, which could adversely affect the market price of our Class A common stock and Class B common stock.

​

Our Second Amended and Restated Certificate of Incorporation (the “Amended Charter”) permits our Board, in its sole discretion, to convert all of the outstanding shares of Class B common stock into shares of Class A common stock based on an exchange ratio determined by a 20-day trailing VWAP for each class of stock. Such conversion of

Class B common stock into Class A common stock could have a dilutive effect on the Company’s earnings per share, which could adversely affect the market price of the Company’s Class A common stock.

​

In addition, our Amended Charter authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over our common stock with respect to dividends and distributions, as our board of directors generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of our Class A common stock and Class B common stock. For example, we could grant the holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of our Class A common stock and Class B common stock.

​

Certain of our directors have significant duties with, and spend significant time serving, entities that may compete with us in seeking acquisitions and business opportunities and, accordingly, may have conflicts of interest in allocating time or pursuing business opportunities.

Certain of our directors hold positions of responsibility with other entities (including Yorktown-affiliated entities) that are in the business of identifying and acquiring coal reserves. The existing positions held by these directors may give rise to fiduciary or other duties that are in conflict with the duties they owe to us. These directors may become aware of business opportunities that may be appropriate for presentation to us as well as to the other entities with which they are or may become affiliated. Due to these existing and potential future affiliations, they may present potential business opportunities to other entities prior to presenting them to us, which could cause additional conflicts of interest. They may also decide that certain opportunities are more appropriate for other entities with which they are affiliated, and as a result, they may elect not to present those opportunities to us. These conflicts may not be resolved in our favor.

​

Our Amended Charter and bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our Class A common stock and Class B common stock.

Our Amended Charter authorizes our board of directors to issue preferred stock without stockholder approval. If our board of directors elects to issue preferred stock, it could be more difficult for a third-party to acquire us. In addition, some provisions of our Amended Charter and bylaws could make it more difficult for a third-party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:

​

​

- limitations on the removal of directors;
- limitations on the ability of our stockholders to call special meetings;
- establishing advance notice provisions for stockholder proposals and nominations for elections to the board of directors to be acted upon at meetings of stockholders;
- providing that the board of directors is expressly authorized to adopt, or to alter or repeal our bylaws; and
- establishing advance notice and certain information requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

​

Our Amended Charter designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our Amended Charter provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of

breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, our Amended Charter or our bylaws, or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. This exclusive forum provision does not apply to a cause of action brought under federal or state securities laws. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of our Amended Charter described in the preceding sentence. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our Amended Charter inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

​

If we fail to maintain an effective system of internal controls, such failure could cause investors to lose confidence in our reported financial information, which could harm our business and have a material adverse effect on the price of our common stock.

​

As described in our Annual Report on Form 10-K for the year ended December 31, 2024, management identified a material weakness in our internal controls over financial reporting related to an insufficiency of appropriately qualified and trained professionals to perform certain control activities necessary to achieve our control objectives. The Company implemented remediation efforts during 2025 to address the material weakness and completed the testing of the design and operating effectiveness of the respective controls. As of December 31, 2025, we concluded that the controls are adequately designed, implemented, and have operated effectively for a sufficient period of time to remediate this previously reported material weakness. Therefore, we concluded that the previously identified material weakness has been remediated as of December 31, 2025. However, our remedial actions may not prevent this or similar weaknesses from occurring in the future.

​

We are required to comply with a variety of reporting, accounting and other rules and regulations. As a result, we maintain a system of internal control over financial reporting, but there are limitations inherent in internal control systems and significant deficiencies or material weaknesses are possible. A control system can provide only reasonable, not absolute, assurance that the objectives of the control system are met. In addition, the design of a control system must reflect the fact that there are resource constraints and the benefit of controls must be appropriate relative to their costs. Furthermore, compliance with existing requirements is expensive and we may need to implement additional finance and accounting and other systems, procedures and controls to satisfy our reporting requirements. If our internal control over financial reporting is determined to be ineffective, or if we are unable to appropriately or timely remediate any such effectiveness, such failure could cause investors to lose confidence in our reported financial information, negatively affect the market price of our common stock, subject us to regulatory investigations and penalties, require us to expend significant resources to remediate the deficiencies, impair our access to capital and otherwise materially adversely impact us.

​

**Risks Related to Our Class B Common Stock Structure**

​

Holders of Class B common stock are common stockholders of the Company and, therefore, are subject to risks associated with an investment in the Company as a whole, even if the holder does not own shares of Class A common stock.

We retain legal title to all of our assets and our tracking stock capitalization does not limit our legal responsibility, or that of our subsidiaries, for the liabilities included in any set of financial statement schedules. Holders of Class B common stock do not have any legal rights related to specific assets attributed to CORE and, in any liquidation, holders of Class B common stock and Class A common stock will be entitled to receive a pro rata share of our available net assets based on their respective numbers of shares.

Our Board’s ability to reattribute businesses, assets and expenses between the Class A common stock and Class B common stock may make it difficult to assess the future prospects of a class of common stock based on past performance.

Our Board currently expects to attribute 100% of the costs associated with the CORE Assets to Ramaco Resources and zero such costs to CORE; however, our Board is vested with discretion to reattribute businesses, assets and liabilities that are attributed to one class of common stock to another class of common stock, without the approval of any of our stockholders. Any such reattribution made by our Board, as well as the existence, in and of itself, of the right to effect a reattribution may impact the ability of investors to assess the future prospects of the businesses and assets attributed to a class of common stock, including liquidity and capital resource needs to pay the projected dividend to holders of our Class B common stock, based on past performance. Stockholders may also have difficulty evaluating the liquidity and capital resources of the businesses and assets attributed to each class of common stock based on past performance, as our Board may use the liquidity of one class to fund the liquidity of another class and capital expenditure requirements through the use of loans and interests between classes.

We could be required to use assets attributed to one class of common stock to pay liabilities attributed to another class.

The assets attributed to one class are potentially subject to the liabilities attributed to another class, even if those liabilities arise from lawsuits, contracts or indebtedness that are attributed to such other class. No provision of our Amended Charter prevents us from satisfying liabilities of one class with assets of another class, and our creditors will not in any way be limited by our tracking stock capitalization from proceeding against any assets they could have proceeded against if we did not have a tracking stock capitalization.

Dividends on our Class B common stock are discretionary and may fluctuate materially quarter to quarter. We cannot guarantee that we will be able to pay dividends in the future or what the actual dividends will be for any future periods.

Our ability to pay dividends is subject to the discretion of our Board, the requirements of applicable law, any statutory or contractual restrictions on the payment of dividends, any prior rights and preferences that may be applicable to any outstanding preferred stock and commercial factors, whether or not attributable to the CORE Assets. We may lack sufficient cash to pay dividends to our Class B stockholders due to cash flow shortfalls attributable to a number of factors, many of which are beyond our control, as well as increases in corporate level general and administrative expenses, principal and interest payments on our outstanding debt, tax expenses, working capital requirements and anticipated cash needs. The timing and amount of dividends declared in future periods will depend on, among other things, (a) our earnings, earnings outlook, production, processing and shipping levels, financial condition, cash flow, cash requirements and our outlook on current and future market conditions, (b) our overall liquidity, (c) the restrictive covenants in the Second Amended and Restated Credit and Security Agreement and any future debt instruments that we may enter into and (d) provisions of applicable law governing the dividends. We have not established a minimum dividend payment for any class of our Common Stock, including our Class B common stock. Further our ability to pay and the amount of dividends declared in future periods may be harmed by other risk factors described herein and incorporated by reference herein. Our ability to pay dividends may fluctuate materially from quarter to quarter, and any quarterly estimate is subject to uncertainty due to the factors described above and elsewhere herein.

The market price of the Class B common stock may not reflect the performance of CORE attributed to it, as we intend.

We cannot assure the holders of Class B common stock that the market price of the Class B common stock related to CORE will, in fact, reflect the performance of CORE attributed to it. Holders of Class B common stock are common stockholders of the Company as a whole and, as such, are subject to all risks associated with an investment in the Company and all of our businesses, assets and liabilities. As a result, the market price of Class B common stock may, in part, reflect events that are intended to be reflected by the Class A common stock of the Company. In addition, investors may discount the value of Class B common stock because it is part of a common enterprise rather than a stand-alone entity.

The market price of the Class B common stock has been volatile, has fluctuated substantially, and could be affected by factors that do not affect traditional common stock.

To the extent the market price of the Class B common stock tracks the performance of more focused classes of businesses and assets than our Class A common stock does, the market price of the Class B common stock may be more volatile than the market price of our existing common stock has been historically. The market price of the Class B common stock may be materially affected by, among other things:

- actual or anticipated fluctuations in CORE’s operating results;

​

- potential acquisition activity by the Company (regardless of the class to which it is attributed) or the companies in which we invest;

​

- issuances of debt or equity securities to raise capital by the Company or the companies in which we invest and the manner in which that debt or the proceeds of an equity issuance are attributed to each of the classes;

​

- changes in financial estimates by securities analysts regarding the Class B common stock, the Class A common stock or CORE attributable to the Class B common stock;

​

- the complex nature and the potential difficulties investors may have in understanding the terms of our new tracking stock, as well as concerns regarding the possible effect of certain of those terms on an investment in our stocks; and

​

- general market conditions.

The market value of the Class B common stock could be adversely affected by events involving the other assets and businesses of the Company.

Because we are the issuer of the Class B common stock, an adverse market reaction to events relating to any of our assets and businesses, such as earnings announcements or announcements of new products or services, acquisitions or dispositions that the market does not view favorably, may cause an adverse market reaction in a particular class of common stock. This could occur even if the triggering event is not material to us as a whole. Certain events may also have a greater impact on one class than the same triggering event would have on another class due to the asset composition of the affected class. In addition, the incurrence of significant indebtedness by us or any of our subsidiaries on behalf of one class, including indebtedness incurred or assumed in connection with acquisitions of or investments in businesses, could affect our credit rating and that of our subsidiaries and, therefore, could increase the borrowing costs of businesses attributable to our other classes or the borrowing costs of the Company as a whole.

We may not pay dividends equally or at all on our classes of common stock.

We have the right to pay dividends on the shares of Class A common stock and Class B common stock in equal or unequal amounts, and we may pay dividends on one class of common stock and not pay dividends on another class. In addition, any dividends or distributions on, or repurchases of, shares relating to a class will reduce our assets legally available to be paid as dividends on another class.

Our tracking stock capital structure could create conflicts of interest, and our Board may make decisions that could adversely affect only the holders of one class of our common stock.

Our tracking stock capital structure could give rise to occasions when the interests of holders of one class of common stock might diverge or appear to diverge from the interests of holders of another class of common stock. Our Class B common stock is not issued by a separate entity and thus holders of Class B common stock do not have the right to elect a separate board of directors. As a result, the Company’s officers and directors owe fiduciary duties to the

Company as a whole and all of our stockholders as opposed to only holders of a particular class of common stock. Decisions deemed to be in the best interest of the Company and all of our stockholders may not be in the best interest of a particular class of common stock when considered independently. Examples include:

​

- decisions as to the terms of any business relationships between classes of common stock;

 ​

- the terms of any reattributions of assets between classes of common stock;

 ​

- decisions as to the allocation of consideration among the holders of Class B common stock and Class A common stock to be received in connection with a merger involving the Company;

 ​

- decisions as to the allocation of corporate opportunities between the classes, especially where the opportunities might meet the strategic business objectives of both classes;

 ​

- decisions as to operational and financial matters that could be considered detrimental to one class but beneficial to the other;

 ​

- decisions as to the conversion of shares of Class B common stock into shares of Class A common stock;

 ​

- decisions regarding the creation of, and, if created, the subsequent increase or decrease of any interest that one class of common stock may own in the other class of common stock;

 ​

- decisions as to the internal or external financing attributable to businesses or assets attributed to any of our classes of common stock;

 ​

- decisions as to the dispositions of assets of any of our classes of common stock; and

 ​

- decisions as to the payment of dividends on any of our classes of common stock.

 ​

Our directors’ or officers’ equity ownership may create or appear to create conflicts of interest.

If directors or officers own disproportionate interests (in percentage or value terms) in Class A common stock or Class B common stock, that disparity could create or appear to create conflicts of interest when they are faced with decisions that could have different implications for the holders of Class A common stock or Class B common stock.

We have not adopted any specific procedures for consideration of matters involving a divergence of interests among holders of Class A common stock or Class B common stock. Rather than develop additional specific procedures in advance, our Board intends to exercise its judgment from time to time, depending on the circumstances, as to how best to:

​

- obtain information regarding the divergence (or potential divergence) of interests;

 ​

- determine under what circumstances to seek the assistance of outside advisers;

 ​

- determine whether a committee of our Board should be appointed to address a specific matter and the appropriate members of that committee; and

 ​

- assess what is in the Company’s best interests and the best interests of all of our stockholders.

Our Board believes the advantage of retaining flexibility in determining how to fulfill its responsibilities in any such circumstances as they may arise outweighs any perceived advantages of adopting additional specific procedures in advance.

Our Board does not expect to formally adopt any management or allocation policies with respect to the CORE Assets.

The Board does not expect to formally adopt any management or allocation policies with respect to the CORE Assets to serve as guidelines in making decisions regarding the relationship between the Company’s overall business and CORE with respect to matters such as tax liabilities and benefits, loans between the two, attribution of assets, financing alternatives, corporate opportunities and similar items. Such determinations are in the sole discretion of our Board and our Board may at any time change or make exceptions to the relationship between CORE and Ramaco Resources. A decision to change, or make exceptions to, these arrangements could disadvantage one class of stockholder while advantaging the other.

Holders of a class of common stock may not have any remedies if any action by our directors or officers has an adverse effect on only that class of common stock.

Principles of applicable law and the provisions of our Amended Charter may protect decisions of our Board that have a disparate impact upon a particular class of common stock. Under applicable law, our Board has a duty to act with due care and in the best interests of all of our stockholders, regardless of the class of stock, or series, they hold. Principles of applicable law established in cases involving differing treatment of multiple classes or series of stock provide that a Board owes an equal duty to all stockholders and does not have separate or additional duties to any subset of stockholders. Judicial opinions in Delaware involving tracking stocks have established that decisions by directors or officers involving differing treatment of holders of tracking stocks may be judged under the business judgment rule. In some circumstances, our directors or officers may be required to make a decision that is viewed as adverse to the holders of a particular series of that stock. Under the principles of applicable law and the business judgment rule referred to above, the holders of Class B common stock may not be able to successfully challenge decisions that they believe have a disparate impact upon the stockholders of one of our classes if a majority of our Board is disinterested and independent with respect to the action taken, is adequately informed with respect to the action taken and acts in good faith and in the honest belief that our Board is acting in the best interest of the Company and all of our stockholders.

Stockholders will not vote on how to attribute consideration received in connection with a merger involving the Company among holders of Class A common stock and Class B common stock.

Our Amended Charter does not contain any provisions governing how consideration received in connection with a merger or consolidation involving the Company is to be distributed to the holders of Class A common stock and Class B common stock, and none of the holders of Class A common stock and Class B common stock will have a separate class vote in the event of such a merger or consolidation. Consistent with applicable principles of applicable law, our Board will seek to divide the type and amount of consideration received in a merger or consolidation involving the Company among holders of Class A common stock and Class B common stock in a fair manner. As the different ways our Board may divide the consideration between holders of the different classes of stock might have materially different results, the consideration to be received by holders of Class B common stock in any such merger or consolidation may be materially less valuable than the consideration they would have received if they had a separate class vote on such merger or consolidation.

We may dispose of assets of CORE without the approval of the Class B common stockholders.

Applicable law requires stockholder approval only for a sale or other disposition of all or substantially all of the assets of the Company taken as a whole, and our Amended Charter does not require a separate class vote in the case of a sale of a significant amount of assets attributed to any of our classes of common stock. As long as the assets attributed to a certain class of common stock proposed to be disposed of represent less than substantially all of our assets, we may approve sales and other dispositions of any amount of the assets of such class without any stockholder approval.

Our Board will decide, in its sole discretion, how to proceed and is not required to select the option that would result in the highest value to holders of any particular class of stock.

Holders of Class B common stock may receive less consideration upon a sale of the assets attributed to that class than if that class were a separate company.

If CORE was a separate, independent company and its shares were acquired by another person, certain costs of that sale, including corporate level taxes, might not be payable in connection with that acquisition. As a result, stockholders of a separate, independent company with the same assets might receive a greater amount of proceeds than the holders of Class B common stock would receive upon a sale of all or substantially all of the assets of CORE. In addition, we cannot assure the holders of Class B common stock that in the event of such a sale the per share consideration to be paid to holders of Class B common stock will be equal to or more than the per share value of that share of stock prior to or after the announcement of a sale of all or substantially all of the assets of CORE. Further, there is no requirement that the consideration paid be tax-free to the holders of Class B common stock. Accordingly, if we sell all or substantially all of the assets attributed to CORE, our Class B stockholders could suffer a loss in the value of their investment in our Class B common stock.

In the event of a liquidation of Ramaco Resources, holders of Class B common stock will not have a priority with respect to the assets attributed to CORE remaining for distribution to stockholders.

Under the Amended Charter, upon Ramaco Resources’ liquidation, dissolution or winding up, holders of Class A common stock and Class B common stock will be entitled to receive, in respect of their shares of such stock, their proportionate interest in all of Ramaco Resources’ assets, if any, remaining for distribution to holders of common stock in proportion to their respective number of shares. Hence, the assets to be distributed to a holder of either class of common stock upon a liquidation, dissolution or winding up of Ramaco Resources will have nothing to do with the value of the assets attributed to the class of common stock or to changes in the relative value of the Class B common stock over time.

Our Board may, in its sole discretion, elect to convert the Class B common stock to Class A common stock, thereby changing the nature of an investment in the Class B common stock and possibly diluting the economic interest in the Company of Class B common stockholders, which could result in a loss in value to such holders.

Our Amended Charter permits our Board, in its sole discretion, to convert all of the outstanding shares of Class B common stock into shares of Class A common stock based on an exchange ratio determined by a 20-day trailing VWAP for each class of stock. A conversion would preclude the holders of Class B common stock from retaining their investment in a security that is intended to reflect separately the performance of CORE. We cannot predict the impact on the market value of our stock of (1) our Board’s ability to effect any such conversion or (2) the exercise of this conversion right by our Board. In addition, our Board may effect such a conversion at a time when the market value of our different stocks could cause the stockholders of one group to be disadvantaged.

Holders of Class A common stock and Class B common stock vote together and have limited separate voting rights.

Holders of Class A common stock and Class B common stock vote together as a single class, except in certain limited circumstances prescribed under applicable law. When holders of Class A common stock and Class B common stock vote together as a single class, holders having a majority of the votes will be in a position to control the outcome of the vote even if the matter involves a conflict of interest among our stockholders or has a greater impact on one class than another.

Transactions in Class B common stock by our insiders could depress the market price of those stocks.

Sales of, or hedging transactions such as collars relating to, shares of Class B common stock by any of our directors or executive officers, could cause a perception in the marketplace that the stock price of the Class B common stock has peaked or that adverse events or trends have occurred or may be occurring at the Company or with respect to the Class B common stock. This perception can result notwithstanding any personal financial motivation for these transactions. As a result, insider transactions could depress the market price for shares of the Class B common stock.

Our capital structure, as well as the fact that CORE is not an independent company, may inhibit or prevent acquisition bids for CORE attributed to the Class B common stock and may make it difficult for a third party to acquire us, even if doing so may be beneficial to our stockholders.

If CORE were a separate independent company, any person interested in acquiring CORE without negotiating with management could seek control of that class by obtaining control of its outstanding voting stock, by means of a tender offer or a proxy contest. Although we intend Class B common stock to reflect the separate economic performance of CORE, it is not a separate entity, and a person interested in acquiring that class of common stock without negotiation with our management could obtain control of that class only by obtaining control of a majority in voting power of all of the outstanding voting shares of the Company. The existence of different classes of common stock could present complexities and in certain circumstances pose obstacles, financial and otherwise, to an acquiring person that are not present in companies that do not have a capital structure similar to ours.

Certain provisions of our Amended Charter and bylaws may discourage, delay, or prevent a change in control of the Company that a stockholder may consider favorable.

These provisions include:

 ​

- authorizing a capital structure with multiple classes of common stock: a Class A common stock and Class B common stock;

​

- classifying our Board with staggered three-year terms, which may lengthen the time required to gain control of our Board;

 ​

- prohibiting stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of the stockholders;

 ​

- limiting who may call special meetings of stockholders;

 ​

- establishing advance notice requirements for nominations of candidates for election to our Board or for proposing matters that can be acted upon by stockholders at stockholder meetings;

 ​

- requiring stockholder approval by holders of at least 66 2/3% of our aggregate voting power with respect to certain extraordinary matters, such as an amendment to our Amended Charter (excluding amendments to Section 4.1 thereof) or bylaws, and the approval by holders of at least 75% of our aggregate voting power for the removal of a director; and

 ​

- the existence of authorized and unissued stock, including “blank check” preferred stock, which could be issued by our Board to persons friendly to our then current management, thereby protecting the continuity of our management, or which could be used to dilute the stock ownership of persons seeking to obtain control of the Company.

​

Risks Related to Our Senior Notes (including 2031 Convertible Senior Notes)

​

The terms of the indentures governing our Senior Notes and the agreements and instruments governing our other indebtedness, including the Credit Agreement, and surety bonding obligations impose restrictions that may limit our operating and financial flexibility.

The indentures governing our Senior Notes and the agreements governing our other indebtedness, including the Credit Agreement, and surety bonding obligations contain certain restrictions and covenants which restrict our ability to incur liens and/or debt or provide guarantees in respect of obligations of any other person and other restrictions, all of which could adversely affect our ability to operate our business, as well as significantly affect our liquidity, and therefore could adversely affect our results of operations.

​

These covenants limit, among other things, our ability to:

​

- incur additional indebtedness under certain circumstances;
- pay dividends on or make distributions in respect of stock or make certain other restricted payments, such as share repurchases;
- make capital investments;
- enter into agreements that restrict distributions from certain subsidiaries;
- sell or otherwise dispose of assets;
- use for general purposes the cash received from certain allowable asset sales or disposals;
- enter into transactions with affiliates;
- create or incur liens;
- merge, consolidate or sell all or substantially all of our assets; and
- receive dividends or other payments from subsidiaries in certain cases.

​

Our ability to comply with these covenants may be affected by events beyond our control and we may need to refinance existing debt in the future. A breach of any of the covenants under the indentures together with the expiration of any cure period, if applicable, could result in a default under our indentures. If any such default occurs, subject to applicable grace periods, the holders of our Senior Notes may elect to declare all outstanding Senior Notes, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. If the obligations under our Senior Notes were to be accelerated, our financial resources may be insufficient to repay the Senior Notes and any other indebtedness becoming due in full.

​

In addition, if we breach the covenants in any indenture governing the Senior Notes and do not cure such breach within the applicable time periods specified therein, we would cause an event of default under the indentures governing the Senior Notes and a cross-default to certain of our other indebtedness and the lenders or holders thereunder could accelerate their obligations. If our indebtedness is accelerated, we may not be able to repay our indebtedness or borrow sufficient funds to refinance it. Even if we are able to obtain new financing, it may not be on commercially reasonable terms or on terms that are acceptable to us. If our indebtedness is in default for any reason, our business, financial condition and results of operations could be materially and adversely affected. In addition, complying with these covenants may make it more difficult for us to successfully execute our business strategy and compete against companies who are not subject to such restrictions.

​

We may be able to incur substantially more debt, which could have important consequences to you.

We may be able to incur substantial additional indebtedness in the future. The terms of the indentures governing the Senior Notes do not prohibit us from doing so. If we incur any additional indebtedness that ranks equally with the Senior Notes, the holders of that debt will be entitled to share ratably with holders of our Senior Notes in any proceeds distributed in connection with any insolvency, liquidation, reorganization or dissolution. This may have the effect of reducing the amount of proceeds paid to holders of our Senior Notes. Incurrence of additional debt would also further reduce the cash available to invest in operations, as a result of increased debt service obligations. If new debt is added to our current debt levels, the related risks that we now face could intensify.

Our level of indebtedness could have important consequences to our stockholders and holders of our Senior Notes, because:

​

- it could affect our ability to satisfy our financial obligations, including those relating to the Senior Notes;

​

- a substantial portion of our cash flows from operations would have to be dedicated to interest and principal payments and may not be available for operations, capital expenditures, expansion, acquisitions or general corporate or other purposes;

​

- it may impair our ability to obtain additional debt or equity financing in the future;

​

- it may limit our ability to refinance all or a portion of our indebtedness on or before maturity;

​

- it may limit our flexibility in planning for, or reacting to, changes in our business and industry; and

​

- it may make us more vulnerable to downturns in our business, our industry or the economy in general.

​

Our operations may not generate sufficient cash to enable us to service our debt. If we fail to make a payment on the Senior Notes, we could be in default on the Senior Notes, and this default could cause us to be in default on other indebtedness, to the extent outstanding. Conversely, a default under any other indebtedness, if not waived, could result in acceleration of the debt outstanding under the related agreement and entitle the holders thereof to bring suit for the enforcement thereof or exercise other remedies provided thereunder. In addition, such default or acceleration may, subject to certain thresholds, result in an event of default and acceleration of the Senior Notes and of other indebtedness of the Company, entitling the holders thereof to bring suit for the enforcement thereof or exercise other remedies provided thereunder. If a judgment is obtained by any such holders, such holders could seek to collect on such judgment from the assets of the Company. If that should occur, we may not be able to pay all such debt or to borrow sufficient funds to refinance it. Even if new financing were then available, it may not be on terms that are acceptable to us.

Our future indebtedness could adversely affect our business, financial condition, results of operations, and ability to meet our payment obligations under the Senior Notes and our other debt.

The use of debt could have significant consequences on our future operations, including:

​

- making it more difficult for us to meet our payment and other obligations under the Senior Notes and our other outstanding indebtedness;

​

- resulting in an event of default if we fail to comply with the financial and other restrictive covenants contained in our financing arrangements, which event of default could result in substantially all of our debt becoming immediately due and payable;

​

- reducing the availability of our cash flow to fund investments, acquisitions and other general corporate purposes, and limiting our ability to obtain additional financing for these purposes;

​

- subjecting us to the risk of increased sensitivity to interest rate increases on our indebtedness with variable interest rates, including borrowings under our financing arrangements;

​

- limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industry in which we operate and the general economy; and

​

- any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the Senior Notes and our other debt.

Our ability to meet our payment and other obligations under our financing arrangements depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us under our financing arrangements or otherwise, in an amount sufficient to enable us to meet our payment obligations under the Senior Notes and our other future debt and to fund other liquidity needs. If we are not able to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, including the Senior Notes, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the Senior Notes and our other debt.

The Senior Notes are unsecured and therefore are effectively subordinated to any secured indebtedness that we currently have or that we may incur in the future and rank pari passu with, which means equal to, all outstanding and future unsecured unsubordinated indebtedness issued by us and our general liabilities.

The Senior Notes are not secured by any of our assets or any of the assets of our subsidiaries. As a result, the Senior Notes are effectively subordinated to any secured indebtedness that we or our subsidiaries currently have outstanding, including indebtedness under our Revolving Credit Facility, equipment loans, and insurance financing arrangements, or may incur in the future (or any indebtedness that is initially unsecured to which we subsequently grant security) to the extent of the value of the assets securing such indebtedness. The indentures governing the Senior Notes do not prohibit us or our subsidiaries from incurring additional secured (or unsecured) indebtedness in the future. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our existing or future secured indebtedness and the secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness and may consequently receive payment from these assets before they may be used to pay other creditors, including the holders of the Senior Notes. The Senior Notes rank pari passu with, which means equal to, all outstanding and future unsecured unsubordinated indebtedness issued by us.

The Senior Notes are structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

The Senior Notes are obligations exclusively of Ramaco Resources, Inc. and not of any of our subsidiaries. None of our subsidiaries is a guarantor of the Senior Notes, and the Senior Notes are not required to be guaranteed by any subsidiaries we may acquire or create in the future. Therefore, in any bankruptcy, liquidation or similar proceeding, all claims of creditors (including trade creditors) of our subsidiaries will have priority over our equity interests in such subsidiaries (and therefore the claims of our creditors, including holders of the Senior Notes) with respect to the assets of such subsidiaries. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still be effectively subordinated to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any such subsidiary senior to our claims. Consequently, the Senior Notes are structurally subordinated to all indebtedness and other liabilities (including trade payables) of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish as financing vehicles or otherwise. The indentures governing the Senior Notes do not prohibit us or our subsidiaries from incurring additional indebtedness in the future. In addition, future debt and security agreements entered into by our subsidiaries may contain various restrictions, including restrictions on payments by our subsidiaries to us and the transfer by our subsidiaries of assets pledged as collateral.

Our subsidiaries conduct the substantial majority of our operations and own our operating assets.

Our subsidiaries conduct the substantial majority of our operations and own our operating assets. As a result, our ability to make required payments on the Senior Notes depends in part on the operations of our subsidiaries and our subsidiaries’ ability to distribute funds to us. To the extent our subsidiaries are unable to distribute, or are restricted from distributing, funds to us, we may be unable to fulfill our obligations under the Senior Notes. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay amounts due on the Senior Notes or to make funds available for that purpose. The Senior Notes are not guaranteed by any of our subsidiaries or any other person.

The indentures under which the Senior Notes have been issued contain limited protection for holders of the Senior Notes.

The indentures under which the Senior Notes have been issued offer limited protection to holders of the Senior Notes. The terms of the indentures and the Senior Notes do not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have an adverse impact on holders of the Senior Notes. In particular, the terms of the indentures and the Senior Notes do not place any restrictions on our or our subsidiaries’ ability to:

- issue debt securities or otherwise incur additional indebtedness or other obligations, including (1) any indebtedness or other obligations that would be equal in right of payment to the Senior Notes, (2) any indebtedness or other obligations that would be secured and therefore rank effectively senior in right of

payment to the Senior Notes to the extent of the value of the assets securing such debt, (3) indebtedness of ours that is guaranteed by one or more of our subsidiaries and which therefore is structurally senior to the Senior Notes and (4) securities, indebtedness or obligations issued or incurred by our subsidiaries that would be senior to our equity interests in our subsidiaries and therefore rank structurally senior to the Senior Notes with respect to the assets of our subsidiaries;

​

- pay dividends on, or purchase or redeem or make any payments in respect of, capital stock or other securities subordinated in right of payment to the Senior Notes;

​

- sell assets (other than certain limited restrictions on our ability to consolidate, merge or sell all or substantially all of our assets);

​

- enter into transactions with affiliates;

​

- create liens (including liens on the shares of our subsidiaries) or enter into sale and leaseback transactions;

​

- make investments; or

​

- create restrictions on the payment of dividends or other amounts to us from our subsidiaries.

​

In addition, the indentures do not include any protection against certain events, such as a change of control, a leveraged recapitalization or “going private” transaction (which may result in a significant increase of our indebtedness levels), restructuring or similar transactions. Furthermore, the terms of the indentures and the Senior Notes do not protect holders of the Senior Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, as they do not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow, or liquidity. Also, an event of default or acceleration under our other indebtedness would not necessarily result in an event of default under the Senior Notes.

Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the Senior Notes may have important consequences for you as a holder of the Senior Notes, including making it more difficult for us to satisfy our obligations with respect to the Senior Notes or negatively affecting the trading value of the Senior Notes.

Other debt we issue or incur in the future could contain more protections for its holders than the indentures and the Senior Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for and trading levels and prices of the Senior Notes.

An increase in market interest rates could result in a decrease in the value of the Senior Notes.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Senior Notes. In general, as market interest rates rise, debt securities bearing interest at fixed rates of interest decline in value. Consequently, if you purchase Notes bearing interest at fixed rates and market interest rates increase, the market values of those Notes may decline. We cannot predict the future level of market interest rates.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Senior Notes.

Any default under the agreements governing our indebtedness, including a default under any future credit facility or other indebtedness to which we may be a party that is not waived by the required lenders, and the remedies sought by the holders of such indebtedness could make us unable to pay principal, premium, if any, and interest on the Senior Notes and substantially decrease the market value of the Senior Notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and

interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our indebtedness, we could be in default under the terms of the agreements governing such indebtedness, including the Senior Notes. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lender under any future credit facility or other debt we may incur in the future could elect to terminate its commitment, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation. In addition, any such default may constitute a default under the Senior Notes, which could further limit our ability to repay our debt, including the Senior Notes. If our operating performance declines, we may in the future need to seek to obtain waivers from the lender under debt that we may incur in the future (for example, under a credit facility) to avoid being in default. If we breach our covenants under such debt and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under the debt, the lender could exercise its rights as described above, and we could be forced into bankruptcy or liquidation. If we are unable to repay debt, lenders having secured obligations could proceed against the collateral securing the debt. Because any future credit facilities will likely have customary cross-default provisions, if the indebtedness under the Senior Notes or under any future credit facility is accelerated, we may be unable to repay or finance the amounts due.

A downgrade, suspension or withdrawal of a credit rating assigned by a rating agency to us or the Senior Notes, if any, could cause the liquidity or market value of the Senior Notes to decline significantly.

Our credit ratings, if any, are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Senior Notes. These credit ratings may not reflect the potential impact of risks relating to the structure or marketing of the Senior Notes. Credit ratings are paid for by the issuer and are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. An explanation of the significance of ratings may be obtained from the rating agency. Generally, rating agencies base their ratings on such material and information, and such of their own investigations, studies and assumptions, as they deem appropriate. We do not undertake any obligation to maintain our credit ratings or to advise holders of Senior Notes of any changes in our credit ratings. There can be no assurance that our credit ratings will remain for any given period of time or that such credit ratings will not be lowered or withdrawn entirely by the rating agency if in their judgment future circumstances relating to the basis of the credit ratings, such as adverse changes in our company, so warrant.

Credit ratings for the Senior Notes could at any time be revised downward or withdrawn entirely at the discretion of the issuing rating agency.

Credit ratings only reflect the views of the issuing rating agency or agencies, and such ratings could at any time be revised downward or withdrawn entirely at the discretion of the issuing rating agency. A rating is not a recommendation to purchase, sell or hold the Senior Notes. Credit ratings do not reflect market prices or suitability of a security for a particular investor and the rating of the Senior Notes may not reflect all risks related to us and our business, or the structure or market value of the Senior Notes. We may elect to issue other securities for which we may seek to obtain a rating in the future. If we issue other securities with a credit rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, could adversely affect the market for or the market value of the Senior Notes.

​

The conditional conversion feature of the 2031 Convertible Senior Notes, if triggered, may adversely affect our financial condition and results of operations.

​

In the event the conditional conversion feature of the 2031 Convertible Senior Notes is triggered, noteholders will be entitled to convert the 2031 Convertible Senior Notes at any time during specified periods at their option. If one or more holders elect to convert their 2031 Convertible Senior Notes, we may, to the extent permitted by, and subject to compliance with the terms of, the agreement governing the Revolving Credit Facility and our other indebtedness in existence at such time, settle a portion or all of our conversion obligation in cash, shares of our Class A common stock, or a combination of cash and shares, at our election and in accordance with the Indenture, and any cash paid could adversely affect our liquidity.

​

The issuance or sale of shares of our Class A common stock, or rights to acquire shares of our Class A common stock, could depress the trading price of our Class A common stock and the 2031 Convertible Senior Notes.

​

We may conduct future offerings of our Class A common stock, preferred stock, or other securities that are convertible into, or exercisable or exchangeable for, our Class A common stock to finance our operations, fund acquisitions, or for other purposes. The sale of shares of our Class A common stock or other securities that are convertible into or exercisable for our Class A common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Class A common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. In addition, upon conversion of the 2031 Convertible Senior Notes, we will pay consideration that consists of cash, shares of our Class A common stock, or a combination of cash and shares of our Class A common stock (together with cash in lieu of any fractional shares, if applicable), at our election. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of Class A common stock or other securities.

​

The Indenture governing the 2031 Convertible Senior Notes does not restrict our ability to issue additional equity securities. If we issue additional shares of our Class A common stock or rights to acquire shares of our Class A common stock, if any of our existing stockholders sells a substantial amount of our Class A common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our Class A common stock, and, accordingly, the 2031 Convertible Senior Notes may significantly decline. In addition, our issuance of additional shares of Class A common stock will dilute the ownership interests of our existing common stockholders, including noteholders who have received shares of our Class A common stock upon conversion of their 2031 Convertible Senior Notes, and any Class A common stock issued upon conversion of the 2031 Convertible Senior Notes may dilute the interests of our existing common stockholders.

​

The accounting method for the 2031 Convertible Senior Notes could adversely affect our reported financial condition and results.

​

The accounting method for reflecting the 2031 Convertible Senior Notes on our balance sheet, accruing interest expense for the 2031 Convertible Senior Notes and reflecting the underlying shares of our Class A common stock in our reported diluted earnings per share may adversely affect our reported earnings and financial condition.

​

In accordance with applicable accounting standards, the 2031 Convertible Senior Notes are reflected as a liability on our balance sheets, with the initial carrying amount equal to the principal amount of the 2031 Convertible Senior Notes, net of issuance costs. The issuance costs are treated as a debt discount for accounting purposes, which will be amortized into interest expense over the term of the 2031 Convertible Senior Notes resulting in lower reported income.

​

In addition, the potential dilutive shares underlying the 2031 Convertible Senior Notes are reflected in our diluted earnings per share using the “if converted” method. The denominator of diluted earnings per share for the 2031 Convertible Senior Notes is determined by multiplying the principal amount of the 2031 Convertible Senior Notes by the applicable conversion rate for the reporting period. The after-tax interest expense associated with the 2031 Convertible Senior Notes is added back to the numerator of the diluted earnings per share calculation for these purposes. However, if reflecting the 2031 Convertible Senior Notes in diluted earnings per share in this manner is anti-dilutive, then the shares underlying the 2031 Convertible Senior Notes will not be reflected in our diluted earnings per share. The application of the if-converted method may reduce our reported diluted earnings per share, and accounting standards may change in the future in a manner that may adversely affect our diluted earnings per share.

​

Furthermore, if any of the conditions to the convertibility of the 2031 Convertible Senior Notes is satisfied, then we may be required under applicable accounting standards to reclassify the liability carrying value of the 2031 Convertible Senior Notes as a current, rather than a long-term liability. This reclassification could be required even if no noteholders convert their 2031 Convertible Senior Notes and could materially reduce our reported working capital.

​

Provisions in the 2031 Convertible Senior Notes and the Indenture governing the 2031 Convertible Senior Notes could delay or prevent an otherwise beneficial takeover of us.

​

Certain provisions in the 2031 Convertible Senior Notes and its Indenture could make a third-party attempt to acquire us more difficult or expensive. For example, if a takeover constitutes a “fundamental change,” then noteholders will have the right to require us to repurchase their 2031 Convertible Senior Notes for cash. In addition, if a takeover constitutes a “make-whole fundamental change” (as defined in the Indenture), then we may be required to temporarily increase the conversion rate. In either case, and in other cases, our obligations under the 2031 Convertible Senior Notes and the Indenture could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management, including in a transaction that noteholders or holders of our Class A common stock may view as favorable.

​

The capped call transactions may affect the value of the 2031 Convertible Senior Notes and our Class A common stock.

​

In connection with the 2031 Convertible Senior Notes, we entered into privately negotiated capped call transactions with the option counterparties. The capped call transactions cover, subject to customary anti-dilution adjustments, the number of shares of our Class A common stock underlying the 2031 Convertible Senior Notes. The capped call transactions are expected generally to reduce the potential dilution to our Class A common stock upon any conversion of the 2031 Convertible Senior Notes and/or offset any potential cash payments we are required to make in excess of the principal amount of converted 2031 Convertible Senior Notes, as the case may be, as a result of conversion of the 2031 Convertible Senior Notes, with such offset subject to a cap.

​

We have been advised that, in connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates entered into various derivative transactions with respect to our Class A common stock and/or purchased shares of our Class A common stock.

​

In addition, the counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our Class A common stock and/or purchasing or selling our Class A common stock or other securities of ours in secondary market transactions following the pricing of the 2031 Convertible Senior Notes and prior to the maturity of the 2031 Convertible Senior Notes (and are likely to do so (i) during any observation period related to a conversion of the 2031 Convertible Senior Notes or following any redemption or fundamental change repurchase of the 2031 Convertible Senior Notes, (ii) following any other repurchase of the 2031 Convertible Senior Notes if we unwind a corresponding portion of the capped call transactions in connection with such repurchase and (iii) if we otherwise unwind all or a portion of the capped call transactions). This activity could also cause or avoid an increase or a decrease in the market price of our Class A common stock or the 2031 Convertible Senior Notes.

​

We are subject to counterparty risk with respect to the capped call transactions.

​

The counterparties to the capped call transactions are financial institutions, or their affiliates, and we will be subject to the risk that one or more of the counterparties may default or otherwise fail to perform, or may exercise certain rights to terminate, their obligations under the capped call transactions. Our exposure to the credit risk of the counterparties is not secured by any collateral.

​

Global economic conditions have in the past resulted in the actual or perceived potential failure or financial difficulties of many financial institutions. If a counterparty to one or more capped call transactions becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under such transactions. Our exposure will depend on many factors but, generally, our exposure will increase if the market price or the volatility of our Class A common stock increases. In addition, upon a default or other failure to perform, or a termination of obligations, by a counterparty, the counterparty may fail to deliver the shares of common stock required to be delivered to us under the capped call transactions and we may experience adverse tax consequences and more dilution than we currently anticipate with respect to our Class A common stock. We can provide no assurances as to the financial stability or viability of any of the counterparties.

​

In addition, the capped call transactions are complex, and they may not operate as planned. For example, the terms of the capped call transactions may be subject to adjustment, modification or, in some cases, renegotiation if certain corporate or other transactions occur. Accordingly, these transactions may not operate as we intend if we are required to adjust their terms as a result of transactions in the future or upon unanticipated developments that may adversely affect the functioning of the capped call transactions.

**General Risk Factors**

Changes in tax legislation could have an adverse impact on our cash tax liabilities, results of operations or financial condition.

The Tax Cuts and Jobs Act of 2017 (“TCJA”) reduced the U.S. corporate income tax rate from 35% to 21% and included certain other changes that resulted in a significant reduction of our income tax liability. The recently enacted One Big Beautiful Bill Act of 2025 (the “OBBBA”) extends many of the policies first enacted in the TCJA and introduces new rules that will impact our business. OBBBA provides for the temporary 2.5% Advanced Manufacturing Production Credit for metallurgical coal. The tax credit for metallurgical coal production is scheduled to terminate after December 31, 2029, limiting our ability to benefit from this incentive to a short window beginning in 2026. Other key provisions of OBBBA include, but are not limited to, (i) restoration of 100% bonus depreciation for qualified property (e.g., machinery and equipment) acquired and placed in service after January 19, 2025, repealing the TCJA’s phase-down that began in 2023, and deduction of domestic research and experimental expenditures in the current period, (ii) new bonus depreciation election allowing the immediate expensing of 100% of the cost basis of “qualified production property” (e.g., manufacturing facilities placed in service in the United States), if construction commences after January 19, 2025, and before January 1, 2029, and the asset is placed in service before January 1, 2031, and (iii) favorable adjustments to the interest deduction rules by permanently restoring the pre-2022 deduction cap on interest expenses with respect to debt incurred in a trade or business to generally 30% of a taxpayer’s EBITDA (as opposed to 30% of EBIT, as required under prior law). The Inflation Reduction Act of 2022 (the “IRA”) added a variety of incentives to promote clean energy, many of which will be reduced or eliminated under the OBBBA. The IRA also added a new corporate alternative minimum tax of 15% on adjusted financial statement income and an excise tax on share buybacks, both of which remain in effect under the OBBBA. Congress could, in the future, revise or repeal those changes or enact other tax law changes, such as the elimination of tax preferences currently available with respect to coal exploration and development and the percentage depletion allowance. We are unable to predict whether any such changes will ultimately be enacted, but any such changes could have a material impact on our cash tax liabilities, results of operations or financial condition.

​

Debt we incur in the future may limit our flexibility to obtain financing and to pursue other business opportunities.

Our future level of debt could have important consequences to us, including the following:

​

- our ability to obtain additional financing, if necessary, for working capital, capital expenditures or other purposes may be impaired, or such financing may not be available on favorable terms;
- our funds available for operations and future business opportunities will be reduced by that portion of our cash flow required to make interest payments on our debt;
- our ability to pay dividends if an event of default occurs and is continuing or would occur as a result of paying such dividend;
- we may be more vulnerable to competitive pressures or a downturn in our business or the economy generally; and
- our flexibility in responding to changing business and economic conditions may be limited.

​

Our ability to service our debt will depend upon, among other things, our future financial and operating performance, which will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service any future indebtedness, we will be forced to take actions such as reducing or delaying our business activities, investments or

capital expenditures, selling assets or issuing equity. We may not be able to effect any of these actions on satisfactory terms or at all.

​

​

The number and quality of viable financing and insurance alternatives available to us may be significantly impacted by unfavorable lending and investment policies by financial institutions and insurance companies associated with concerns about environmental impacts of coal combustion, and negative views around our efforts with respect to environmental and social matters and related governance considerations could harm the perception of our company by a significant number of investors or result in the exclusion of our securities from consideration by those investors.

Certain banks, other financing sources and insurance companies have taken actions to limit available financing and insurance coverage for the development of new coal-fueled power plants and coal producers and utilities that derive a majority of their revenue from coal, and particularly from thermal coal. This may adversely impact the future global demand for coal. Increasingly, the actions of such financial institutions and insurance companies are informed by non-standardized “sustainability” scores, ratings and benchmarking studies provided by various organizations that assess environmental, social and governance matters. Further, there have been efforts in recent years by members of the general financial and investment communities, including investment advisors, sovereign wealth funds, public pension funds, universities and other institutional investors, to divest themselves and to promote the divestment of securities issued by companies involved in the fossil fuel extraction market, or that have low ratings or scores in studies and assessments of the type noted above, including coal producers. These entities also have been pressuring lenders to limit financing available to such companies. These efforts may have adverse consequences, including, but not limited to:

​

- restricting our ability to access capital and financial markets in the future;
- reducing the demand and price for our equity securities;
- increasing the cost of borrowing;
- causing a decline in our credit ratings;
- reducing the availability, and/or increasing the cost of, third-party insurance;
- increasing our retention of risk through self-insurance;
- making it more difficult to obtain surety bonds, letters of credit, bank guarantees or other financing; and

*·* limiting our flexibility in business development activities such as mergers, acquisitions and divestitures.

If securities or industry analysts adversely change their recommendations regarding our stock or if our operating results do not meet their expectations, our stock price could decline.

The trading market for our common stock could be influenced by the research and reports that industry or securities analysts may publish about us or our business. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover our company downgrade our stock or if our operating results do not meet their expectations, our stock price could decline.

Our ability to operate effectively could be impaired if we fail to attract and retain key personnel.

The loss of our senior executives could have a material adverse effect on our business. There may be a limited number of persons with the requisite experience and skills to serve in our senior management positions. We may not be able to locate or employ qualified executives on acceptable terms. In addition, as our business develops and expands, we believe that our future success will depend greatly on our continued ability to attract and retain highly skilled personnel with coal industry experience. We may not be able to continue to employ key personnel or attract and retain qualified personnel in the future. Our failure to retain or attract key personnel could have a material adverse effect on our ability to effectively operate our business.

​

We could fail to retain customers or gain new ones.

The failure to obtain additional customers or the loss of all or a portion of the revenues attributable to any customer as a result of competition, creditworthiness, inability to negotiate extensions or replacement of contracts or otherwise, could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay dividends to our stockholders.

​

Terrorist attacks or cyber-incidents could result in information theft, data corruption, operational disruption and/or financial loss.

Like most companies, we have become increasingly dependent upon digital technologies, including information systems, infrastructure and cloud applications and services, to operate our businesses, process and record financial and operating data, communicate with our business partners, analyze mine and mining information, estimate quantities of coal reserves, as well as other activities related to our businesses. Strategic targets, such as energy-related assets, may be at greater risk of future terrorist or cyber-attacks than other targets in the United States. Deliberate attacks on, or security breaches in, our systems or infrastructure, or the systems or infrastructure of third parties, including systems that collect, organize, store or use personal data, or cloud-based applications could lead to corruption or loss of our proprietary data and potentially sensitive data, delays in production or delivery, difficulty in completing and settling transactions, challenges in maintaining our books and records, environmental damage, communication interruptions, other operational disruptions and third-party liability. Due to the nature of cyber-attacks, breaches to our or our service or equipment providers’ systems could go unnoticed for a prolonged period of time. Our insurance may not protect us against such occurrences. Consequently, it is possible that any of these occurrences, or a combination of them, could have a material adverse effect on our business, reputation, financial condition, results of operations and cash flows. Further, as cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber incidents.

​

Failure to adequately protect critical data and technology systems and the impact of data privacy regulation could materially affect us.

Information technology solution failures, network disruptions and breaches of data security could disrupt our operations by causing delays or canceling or impeding processing of transactions and reporting financial results, resulting in the unintentional disclosure of employee, royalty owner, or other third party or our confidential information, or damage to our reputation. There can be no assurance that a system failure or data security breach will not have a material adverse effect on our operations, financial condition, results of operations or cash flows. In addition, new laws and regulations governing data privacy and the unauthorized disclosure of confidential information pose increasingly complex compliance challenges and potentially elevate costs, and any failure to comply with these laws and regulations (or contractual provisions requiring similar compliance) could result in significant penalties and legal liability, require us to change our business practices, increase the costs and complexity of compliance, and adversely affect our business. As noted above, we are also subject to the possibility of cyber incidents or attacks, which themselves may result in a violation of these laws or may result in significant expense.

​

We may be subject to securities litigation, which could result in significant costs and divert management’s attention and resources.

Securities class action lawsuits and other securities litigation are frequently filed against public companies following periods of volatility in the market price of their securities or upon the announcement of unexpected adverse developments. If the market price of our securities experiences significant volatility, or if we report unexpected operating results, become subject to regulatory inquiries, or experience other negative developments, we could be targeted in securities class action or derivative lawsuits. Any such matters, even if ultimately resolved in our favor, could be costly to defend, require significant time and attention from management and other employees, result in substantial

judgments or settlements, increase the cost or reduce the availability of directors’ and officers’ liability insurance, and adversely affect our reputation, business, financial condition, results of operations and cash flows.

We may be subject to litigation, the disposition of which could negatively affect our profitability and cash flow in a particular period, or have a material adverse effect on our business, financial condition and results of operations.

Our profitability or cash flow in a particular period could be affected by an adverse ruling in any litigation that may be filed against us in the future. In addition, such litigation could have a material adverse effect on our business, financial condition and results of operations. See “Part I, Item 3. Legal Proceedings.”

## Item 1B. Unresolved Staff Comments

The Company received a comment letter, dated August 19, 2025, from the staff of the Division of Corporation Finance of the SEC (the “Staff”) relating to our Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2025. The Staff’s comments principally concerned: (i) our disclosures and public statements regarding the Fluor Study for the Brook Mine rare earth elements and critical minerals project, including the basis for statements characterizing the project as technically and economically viable in light of the AACE Class 5 classification and the conceptual nature of the underlying exploration target; (ii) the consistency of our disclosures regarding the preparation of the Fluor Study under Regulation S-K Subpart 1300 with our release of a Company-prepared summary and references to the AACE classification system; and (iii) whether our plans to commence carbon ore mining activities and to construct a pilot-scale concentrate processing facility could result in a material change to our operating results or financial condition in future periods, and our related considerations under Item 303 of Regulation S-K.

In response, we explained that the conclusions regarding technical and economic viability referenced in our disclosures were those of Fluor Corporation as set forth in its conceptual study, based on then-available information and Company-provided pricing, and that the Class 5 designation reflects the preliminary level of project definition and expected accuracy for early-stage cost estimates. We also clarified that our Company-prepared summary of the Fluor Study was released in accordance with the disclosure framework of Regulation S-K Subpart 1300, that the summary was not a Technical Report Summary under Subpart 1300 and appropriately referenced the AACE classification system. We committed to update the operating results and financial conditions if they change in future periods.

We have not received further communication from the Staff regarding these matters, and the comments therefore remain unresolved as of the date of this Annual Report.

## Item 1C. Cybersecurity

We have become increasingly dependent upon technology, including information systems as well as infrastructure and cloud applications and services. These technologies are used to operate our businesses, process and record financial and operating data, communicate with our business partners, analyze mining information, estimate quantities of coal reserves, and perform other activities related to our business.

Ramaco uses third parties to manage its information technology (“IT”) infrastructure. The Company’s process for assessing, identifying, and managing material cybersecurity risks includes the following activities, all of which are performed or assisted by third parties with considerable experience providing managed IT and security services or IT assurance services:

- Assessment of cybersecurity risks, using the National Institute of Standards and Technology Cybersecurity Framework as a guide, as part of the overall IT risk assessment performed annually;
- Network operations center monitoring to establish baseline metrics and assist with anomaly detection;
- Periodic vulnerability scanning;
- Configuration of firewall, antivirus, and malware protection as well as alert thresholds;
- Generation of system audit logs and recovery backups;
- Preparation of an incident response plan and assignment of team members;
- Logical access security reviews for applications and data protection; and
- Awareness training for employees on cybersecurity threats and safe practices.

The Company also uses applications hosted by a reputable third party that are critical to managing Ramaco’s business and financial records. The process to oversee and identify cyber risks associated with the third-party service provider involves reviewing its annual System and Organization Controls 2 (“SOC 2”), Type 2 Report as well as conducting recurring status meetings with the third party.

The responsibility for managing and assessing material risks from cybersecurity threats lies with the Company’s IT Steering Committee, which met quarterly during 2025. The IT Steering Committee is made up of five members of senior management having legal or corporate finance backgrounds. The committee also includes one lead representative of the third-party IT management and security service providers utilized by the Company to mitigate cybersecurity risks as discussed above. Information regarding cybersecurity risks and mitigation efforts is reported periodically by the IT Steering Committee to the Company’s chief executive officer, chief financial officer, and Audit Committee. The Audit Committee is primarily responsible for the Board of Directors’ oversight of cybersecurity risks. The Company created and hired a new role in early 2025, Vice President of Information Technology and Cybersecurity, which enhanced the management and oversight of cybersecurity.

We have not experienced any cybersecurity incidents to date that have materially affected, or are reasonably likely to materially affect, the Company’s business strategy, results of operations, or financial condition. However, cybersecurity threats are constantly evolving, and we may not be successful in preventing or mitigating a cybersecurity incident despite our efforts to protect against such risks. A successful cyberattack could lead to theft of sensitive information, ransomware, destruction of data, or other issues causing financial, legal, or reputational damage. These events are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition, should they occur.

## Item 2. Properties

Summary Overview of Mining Operations

​

Information concerning our mining properties in this Annual Report has been prepared in accordance with the requirements of subpart 1300 of Regulation S-K, which requires us to disclose our mineral resources, in addition to our mineral reserves, as of the end of our most recently completed fiscal year both in the aggregate and for each of our individually material mining properties.

​

As used in this Annual Report, the terms “mineral resource,” “measured mineral resource,” “indicated mineral resource,” “inferred mineral resource,” “mineral reserve,” “proven mineral reserve” and “probable mineral reserve” are defined and used in accordance with subpart 1300 of Regulation S-K. Under subpart 1300 of Regulation S-K, mineral resources may not be classified as “mineral reserves” unless the determination has been made by a qualified person that the indicated and measured mineral resources can be the basis of an economically viable project. You are specifically cautioned not to assume that any part or all of the mineral resources will ever be converted into mineral reserves, as defined by the SEC. See “Item 1A “Risk Factors”

​

You are cautioned that, except for that portion of mineral resources classified as mineral reserves, mineral resources do not have demonstrated economic value. Inferred mineral resources are estimates based on limited geological evidence and sampling and have too high of a degree of uncertainty as to their existence to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Estimates of inferred mineral resources may not be converted to a mineral reserve. It is reasonable to expect that the majority of inferred mineral resources could be upgraded to indicated or measured mineral resources with continued exploration. A significant amount of exploration must be completed in order to determine whether an inferred mineral resource may be upgraded to a higher category. You are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted to mineral reserves. See “Item 1A “Risk Factors”

​

The information that follows relating to the Elk Creek Complex, Berwind Complex, Knox Creek Complex, and Maben Complex is derived, for the most part, from, and in some instances is an extract from, the TRS relating to such properties prepared in accordance with the Item 601(b)(96) and subpart 1300 of Regulation S-K. Further details on the supporting information to this summary content is available in the respective TRS. Reference should be made to the full text of the TRSs, incorporated herein by reference and made a part of this Annual Report.

​

Item 2 Properties, Figure 1 below shows the location of our mining properties and offices as of December 31, 2025:

​

​

At December 31, 2025, we had four mining properties, as summarized in the table below (tons produced in 000s), excluding the RAM Mine and Brook Mine properties:

​

| Line item | Location | Controlled / Acres | Yrs | Stage | Clean Tons / Produced / 2023 | Clean Tons / Produced / 2024 | Clean Tons / Produced / 2025 | Mine Type | Quality | Processing Facilities - / Transportation |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| Elk Creek Complex | Logan, Wyoming, and Mingo Counties, WV | 20,200 | 15 | Production | 2,031 | 2,286 | 2,719 | Underground, Highwall, Surface | High Volatile A, A/B, B | Elk Creek Preparation Plant - CSX RR, Truck |
| Berwind Complex | McDowell County, WV, Buchanan and Tazewell Counties, VA | 62,500 | 20+ | Production | 601 | 794 | 698 | Underground, Highwall, Surface | Low and Mid Volatile | Berwind Preparation Plant - Truck, Norfolk Southern RR |
| Knox Creek Complex | McDowell County, WV, Buchanan, Russell, and Tazewell Counties, VA | 88,850 | 30 | Production | 370 | 326 | 164 | Underground, Highwall, Surface | Mid and High Volatile A | Knox Creek Preparation Plant - Truck, Norfolk Southern RR |
| Maben Complex | Wyoming and Raleigh Counties, WV | 28,000 | 15 | Production | 172 | 265 | 244 | Underground, Highwall, Surface | Low Volatile | Maben Preparation Plant - Truck, Norfolk Southern RR |
| Total |  | 199,550 |  |  | 3,174 | 3,671 | 3,826 |  |  |  |

​

At December 31, 2025, we owned or controlled, primarily through long-term leases, approximately 199,550 acres of coal in Virginia and West Virginia and 1,567 acres of coal in Pennsylvania. The aggregate annual production for our properties during the three most recently completed fiscal years are as follows: 3.8 million tons for fiscal year 2025, 3.7 million tons for fiscal year 2024, and 3.1 million tons for fiscal year 2023. Our preparation plants and loadout facilities are located on properties owned by us or held under leases which expire at varying dates over the next 30 years. Most of the leases contain options to renew. Many of these leases provide for a royalty payment to the lessor based on a specific price per ton of coal extracted or as a percentage of coal sales revenue. We believe that all of our leases were entered into at market terms.

​

The Company leases office space in Lexington, Kentucky, which serves as our executive headquarters as well as Charleston, West Virgina, which serves as an operations center. The Company also owns offices in Sheridan, Wyoming. See Item 1. “Business - Our Projects” for additional information about our mining operations and Wyoming initiatives.

​

We hold numerous environmental and mineral extraction permits, water rights and other permits, licenses and approvals from governmental authorities authorizing operations at each of our facilities. With respect to each facility at which we produce coal, permits, licenses and approvals are obtained as needed in the normal course of business based on our mine plans and federal, state, and local regulatory provisions regarding mine permitting and licensing. Based on our historical permitting experience, we expect to be able to continue to obtain necessary mining permits and approvals to support historical rates of production.

​

We are the operators of the mining and processing operations and the mining methods we use consist of surface, underground and highwall mining methods. The mining operations for the Elk Creek, Berwind, Knox Creek, and Maben complexes are material to our business and are further described below.

​

​

​

​

​

​

Elk Creek Complex

​

The Elk Creek Complex is located approximately 45 miles south of Charleston, West Virginia, in Logan, Wyoming, and Mingo Counties at N 37.698718, W 81.778297. The nearest town is Man, West Virginia, which is approximately five miles to the northwest of the Elk Creek Complex. The Elk Creek Complex is within the Southern West Virginia coal field of the Central Appalachia Coal Producing Region (the “CAPP Region”) of the United States.

​

Companies that previously mined on the Elk Creek Complex include Island Creek Coal Company (“Island Creek”) which started mining in the area in December 1904. Consolidation Coal Company, now known as Core Natural Resources, Inc. (“Core Nature Resources”), bought Island Creek in July 1993 and continued operations in and around the area until the late-1990s when Core Natural Resources idled its Elk Creek Mine. Ramaco Coal bought the property from Core Natural Resources in 2012 and started production on the Elk Creek Complex in the fourth quarter of 2016. The 2012 purchase included acquisition of rail access, permitted impoundment and coal refuse disposal facilities, as well as numerous reclaimed, but permitted deep mines. Pittston Coal Company operated mines on the northern Huff Creek portion (McDonald and Baisden properties) of the Elk Creek Complex in the 1970s and 1980s before the company exited the coal mining business in 2001.

​

The Elk Creek Complex consists of approximately 20,200 acres of leased coal holdings. Within the Elk Creek Complex controlled coal holdings, 16,000 acres lie in Logan County, 2,800 acres in Wyoming County and 1,400 acres in Mingo County. The Elk Creek Complex is in the production stage and currently has seven active mines, two planned and permitted mines, two permitted inactive mines, and one planned but not permitted mine. The four planned and/or permitted mines include one contour surface mine developing area for a highwall miner, and three underground room and pillar mines, which use continuous miners for mine development. Ramaco began production of metallurgical coal at the complex in 2016. A majority of the underground mines implement retreat mining, which results in mining recovery of greater than 80 percent. Contour mining has an average mining recovery of approximately 90 percent, and the highwall mines have an average mining recovery of approximately 40 percent.

​

The Elk Creek Complex is mining several seams and seam splits, including the Chilton A, Upper Dorothy, Upper Dorothy 2, 3, and 4, Middle Dorothy, Lower Dorothy, Upper Cedar Grove, Lower Cedar Grove A, Lower Cedar Grove B, Lower Cedar Grove C, Upper Alma, Lower Alma, Powellton, Eagle, and No. 2 Gas seams, in descending stratigraphic order.

​

Currently, there are seven active mines within the complex:

- Ram No. 1 Surface and Highwall Mine
- Ram No. 3 Surface and Highwall Mine
- Stonecoal No. 2 Alma Deep Mine
- Rockhouse Eagle Deep Mine
- No. 2 Gas Deep Mine
- Michael Powellton Deep Mine
- Crucible Deep Mine Lower Cedar Grove B and C seams

​

There are two planned and permitted mines within the complex:

- Ram No. 2 Surface and Highwall Mine (which is the extension of Ram No. 1 above)
- Glen Alum Tunnel #1 Deep Mine

​

There are two permitted inactive mines, the Eight-Kay Deep Mine and the Monarch Deep Mine. The Bens Creek Deep Mine is planned but is not yet permitted. It is likely future mines will be planned and scheduled, as necessary, from resource areas within the complex, to meet internal Ramaco production goals aligned with market conditions. With the exception of the Ram No. 2 mine, all planned mines are subject to future Board approval.

​

The current Elk Creek Complex Life-of-Mine (“LOM”) Plan projects mining through 2040; an expected mine life for the complex of 15 years. However, it is likely that future mines will be planned and scheduled, as necessary, to meet our production goals aligned with market conditions.

​

All Run-of-Mine (“ROM”) coal is washed at the Elk Creek Preparation Plant. The Elk Creek Preparation Plant, built in 2017 by Raw Resources Group located in Princeton, West Virginia, is a well designed and constructed preparation plant, with ROM processing capacity of 700 tons per hour. During 2022, we began work on a throughput upgrade at our Elk Creek Preparation plant. We completed the expansion in 2023, which raised the nameplate processing capacity to 1,050 raw tons per hour and our annual processing capacity from this complex to approximately three million tons per year.

​

In order to utilize the increased capacity, we also completed development work on additional low-cost, high- volatile mines at Elk Creek during 2024, including the Ram 3 surface/highwall mine and the third section at the Stonecoal Alma mine, both of which were at full production by the end of the third quarter of 2024.

​

The gross investment in the Elk Creek Complex mining property and its associated plant and equipment was $459 million as of December 31, 2025. The Elk Creek Complex utilizes industry standard, modern surface and underground mining equipment, processing equipment, and infrastructure that is in good operating condition and capable of meeting planned production requirements using prudent operating methods and operating schedules.

​

The Elk Creek Complex produces high-quality, high-volatile metallurgical coal. Historically, the market for metallurgical coal from the Elk Creek Complex has been domestic metallurgical coal consumers and the global seaborne metallurgical coal market. Coal produced from the complex is primarily high-volatile A and high-volatile B metallurgical coal. The Elk Creek Complex also produces thermal coal and specialty coals, which typically represents less than five percent of sales in any given year.

​

Volatiles refers to the volatile matter contained in the coal. Classification of coal as low, mid or high-volatile refers to the specific volatile content within the coal, with coals of 17% to 22% volatile matter being classified as low-volatile, 23% to 31% as mid-volatile and 32% or greater as high-volatile. The volatile matter in coal impacts coke yield (i.e., the amount of coke and coke by-products produced per ton of coal charged). Low-volatile coal contains more carbon, but too much carbon can result in coke oven damage. Too much volatile matter results in less carbon and reduces the volume of coke produced. Therefore, coke producers use blends of high-volatile and low-volatile coals for coke production.

​

We are unaware of any significant encumbrances to the Elk Creek Complex, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines.

​

Berwind Complex

​

The Berwind Complex is located approximately 80 miles south of Charleston, West Virginia; 100 miles west of Roanoke, Virginia; 60 miles northeast of Kingsport, Tennessee; and 160 miles east/southeast of Lexington, Kentucky at N 37.164522, W 81.744893. The complex includes areas in Buchanan and Tazewell Counties, Virginia and McDowell County, West Virginia. The Berwind Complex is within the Southwestern Virginia and Southern West Virginia coal fields of the CAPP Region of the United States.

​

The Berwind Complex and surrounding area have an extensive history of coal mining, primarily by underground mining methods. Mining within the Berwind/Knox Creek Complex likely began in the early-1900s and there have been many different mine operators both large and small in the region since then.

​

The Berwind Property consists of approximately 62,500 acres of leased coal holdings located in McDowell County, West Virginia and Buchanan and Tazewell Counties, Virginia. Ramaco obtained its initial lease for this property in 2015 and commenced mine operations in 2017. The Berwind Complex is in the production stage and currently has two active mines. The mines that were active at December 31, 2025 are underground room and pillar mines, which use continuous miners for mine development.

​

Ramaco started operations at the Berwind Pocahontas 4 Deep Mine in 2017 and idled the mine in mid-July 2022 due to an ignition that an investigation by the Mine Safety and Health Administration (MSHA) suggests was

caused by lightning that struck a pilot hole for a new shaft. Production at the Berwind No. 1 Deep Mine restarted in the first quarter of 2023. The Company continues to increase production at the main Berwind low-volatile mine.

A majority of the underground mines implement retreat mining, which typically results in mining recovery of greater than 80 percent. Contour mining has an average mining recovery of approximately 90 percent, and the highwall mine has an average mining recovery of approximately 40 percent.

​

The Berwind Complex is mining several seams and seam splits, including the Pocahontas 6, Pocahontas 5, Pocahontas 4 and Pocahontas 3 seams, in descending stratigraphic order.

​

Active Mines:

- Laurel Fork Pocahontas 3 Deep Mine
- Berwind No. 1 Pocahontas 4 Deep Mine

​

Permitted Mines:

- Squire Jim No. 1 Deep Mine

​

The current Berwind Complex Life-of-Mine (LOM) Plan projects mining through 2049, an expected mine life for the complex of over 20 years. However, it is likely that future mines will be planned and scheduled, as necessary, from resource areas within the complex, to meet internal Ramaco production goals aligned with market conditions.

​

All Run-of-Mine (ROM) coal is washed at the Berwind Preparation Plant with no planned direct shipment coal. The Berwind Preparation Plant was initially built in 1955 and commissioned in 1957. Ramaco refurbished the preparation plant in 2021 and 2022 based on a design by Ramsey Industrial, with a current ROM processing capacity of 600 tons per hour.

​

The gross investment in the Berwind Complex mining property and its associated plant and equipment was $240 million as of December 31, 2025. The Berwind Complex utilizes industry standard, modern surface and underground mining equipment, processing equipment, and infrastructure that is in good operating condition and capable of meeting planned production requirements using prudent operating methods and operating schedules.

​

The Berwind Complex produces high-quality, mid and low-volatile metallurgical coal. Historically, the market for metallurgical coal from the Berwind Complex has been for both domestic metallurgical coal consumers and the global seaborne metallurgical coal market.

​

We are unaware of any significant encumbrances to the Berwind Complex, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines.

​

Knox Creek Complex

​

The Knox Creek Complex consists of two general properties or areas as follows:

- Big Creek Property
- Knox Creek Property

​

The Knox Creek Complex is located approximately 90 miles south of Charleston, West Virginia; 110 miles west of Roanoke, Virginia; 50 miles northeast of Kingsport, Tennessee; and 150 miles east/southeast of Lexington, Kentucky at N 37.108, W 81.9106. The complex includes areas in Buchanan, Russell and Tazewell Counties, Virginia and McDowell County, West Virginia. The Knox Creek Complex is within the Southwestern Virginia and Southern West Virginia coal fields of the CAPP Region of the United States.

​

The Knox Creek Complex and surrounding area have an extensive history of coal mining, primarily by underground mining methods. Mining within the Knox Creek Complex likely began in the early-1900s and there have been many different mine operators both large and small in the region since then.

​

The Knox Creek Complex consists of approximately 88,850 acres of owned and leased coal holdings. Within the Knox Creek Complex controlled coal holdings, 5,370 acres lie in McDowell County, West Virginia. The Knox Creek Complex is in the production stage and currently has one active mine and two planned and permitted mines. The single active mine is a contour surface mine developing areas for a highwall miner. The Company closed the Jawbone No. 1 Deep Mine during 2024, which was nearing end of mine life and experiencing higher cost production. The Company acquired approximately 24,800 acres in November 2025 from Coranado IV, LLC, and Buchanan Minerals, referred to as the Russell County property. Through this acquisition Ramaco extended the mine life for Big Creek Surface mine by an additional five years. Further engineering work is being completed to evaluate additional potential coal areas.

​

Ramaco began production of metallurgical coal at the complex in 2019. The underground mines will implement retreat mining, which typically results in mining recovery of 50 to 80 percent. At the surface mine, contour mining has an average mining recovery of approximately 90 percent, and highwall mining has an average mining recovery of approximately 40 percent.

​

The Knox Creek Complex is mining or plans to mine several seams and seam splits, including the Jawbone, Kennedy and Tiller seams.

​

Active Mine:

- Big Creek Surface

​

Planned and Permitted Mines:

- Knox Creek Tiller Deep Mine
- Kennedy No. 3 Deep Mine

​

Closed Mines:

- Big Creek Jawbone No. 1 Deep Mine was active during most of 2024, but was closed later in the year and is no longer active

​

We estimate that the mine life for the Knox Creek Complex is 30 years. It is anticipated that future mines will be planned and scheduled, as necessary, from resource areas within the complex, to meet internal Ramaco production goals aligned with market conditions. Both planned mines listed above are subject to future Board approval.

​

All Run-of-Mine (ROM) coal is washed at the Knox Creek Preparation Plant. The Knox Creek Preparation Plant, built in 1981 by Powell Construction Company located in Johnson City, Tennessee, is a well designed and constructed preparation plant, with ROM processing capacity of 750 tons per hour.

​

The gross investment in the Knox Creek Complex mining property and its associated plant and equipment was $53 million as of December 31, 2025. The Knox Creek Complex utilizes industry standard, modern surface and underground mining equipment, processing equipment, and infrastructure that is in good operating condition and capable of meeting planned production requirements using prudent operating methods and operating schedules.

​

The Knox Creek Complex produces high-quality, mid and high-volatile metallurgical coal. Historically, the market for metallurgical coal from the Knox Creek Complex has included both domestic metallurgical coal consumers and the global seaborne metallurgical coal market. The Knox Creek Complex also sporadically produces a minimal quantity of thermal coal from the surface mine from oxidized zones.

​

We are unaware of any significant encumbrances to the Knox Creek Complex, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines.

​

Maben Complex

​

The Maben Complex is located approximately 52 miles south of Charleston, WV; 80 miles west of Roanoke, Virginia; 100 miles northeast of Kingsport, Tennessee; and 170 miles east/southeast of Lexington, Kentucky at N 37.6525, W 81.3867.

​

The Maben Complex and surrounding area have an extensive history of coal mining, primarily by contour surface and underground mining methods. Mining within the area likely began in the early-1900s, and there have been many different mine operators both large and small in the region since then. The Maben Coal Company, unrelated to Ramaco, was one of the primary operators on the Maben property and in the region. Pocahontas Coal Company also had a presence in the region.

​

The Maben property consists of approximately 28,000 acres of controlled mineral rights acquired from the purchase of Maben Coal in the third quarter of 2022 from Appleton Coal, LLC. As part of the transaction, we assumed existing mining permits issued by the West Virginia Department of Environmental Protection, which authorizes mining by both surface and highwall mining methods as well as by underground methods. We also assumed issued permits covering an existing haul road, as well as an active refuse disposal area together with a preparation plant and unit train loadout, neither of which had been constructed at the closing date. During 2024, the Company completed the purchase of an existing coal preparation plant and relocated the plant to the Maben Complex, which was commissioned early in the fourth quarter of 2024.

​

The Maben Complex is in the production stage and currently has one active mine and three planned underground mines.

​

Active Mine:

- Maben Surface and Highwall Mine

​

Planned and Permitted Mines:

- Beckley Crystal Deep Mine
- Allen Creek Mine No. 1

​

Planned and Unpermitted Mine:

- Slick Rock Sewell Deep Mine

​

The current expected mine life for the complex is 15 years; however, it is anticipated that future mines will be planned and scheduled, as necessary, from resource areas within the complex, to meet internal Ramaco production goals aligned with market conditions.

​

The gross investment in the Maben Complex mining property and its associated plant and equipment was $74 million as of December 31, 2025. The Maben Complex utilizes industry standard, modern surface and highwall mining equipment, processing equipment, and infrastructure that is in good operating condition and capable of meeting planned production requirements using prudent operating methods and operating schedules.

​

The Maben Complex produces high-quality, low-volatile metallurgical coal, which serves both domestic metallurgical coal consumers and the global seaborne metallurgical coal market.

​

We are unaware of any significant encumbrances to the Maben Complex, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines.

​

Brook Mine

​

The Brook Mine is an exploration stage property located approximately nine miles northwest of Sheridan, Wyoming in Sheridan County, Wyoming. The Brook Mine is located within the Sheridan Coal Field within the northwestern portion of the Powder River Basin coal producing region of the United States.

​

Mining activity in and around the Brook Mine dates back to the late 19th century, when underground coal mining began in the Sheridan Coal Field around 1894 and continued through 1953, with major operations (the Dietz, Acme, Model, Carney, Monarch, and Kooi mines) eventually consolidated under the Sheridan Wyoming Coal Company and later acquired by Pittston. Subsequent large scale surface mining was carried out by Big Horn Coal Company

beginning in the 1950s, with production peaking at roughly one million tons per year in 1970 before operations ceased in 2000.

​

The Brook Mine consists of approximately 15,800 acres of Ramaco owned and leased surface and mineral holdings located in Sheridan County, Wyoming. The property was acquired as part of the purchase of Ramaco Coal during 2022.

​

A mineral resource estimate was released for the Brook Mine in September 2025 based on a TRS of the Brook Mine completed by Weir, which was subsequently revised in July 2026 (which is current as of December 31, 2025) and is filed as Exhibit 96.5 hereto. The qualified persons that prepared the revised Brook Mine TRS are employees of Weir, except for Mr. Mike Woloschuk, who is an employee of Ramaco. The TRS utilizes certain project-specific technical information included in the Fluor Study, a conceptual study prepared by Fluor Corporation. The Fluor Study was not prepared in accordance with Regulation S-K Subpart 1300 requirements. The mineral resource estimates are not mineral reserves and do not meet the threshold for reserve modifying factors that would allow for conversion to mineral reserves. There is no certainty that any part of the initial resource estimates will be converted into reserves.

​

The Company continues to evaluate the commercial and technical feasibility of extracting critical minerals, including rare earth elements within the current Brook Mine permit area. Preliminary findings indicate elevated concentrations of a number of rare earth elements and other critical minerals which include heavy magnetic rare earth elements, like terbium and dysprosium, and critical minerals, like gallium, germanium and scandium.

​

Additional drilling and sampling has occurred since the issuance of the September 2025 TRS. Weir has reviewed the three completed holes and determined that the new assays are in-line with the results of the TRS. Once all sampling and analysis is complete, a detailed assessment will be completed to incorporate the latest exploration information into the mineral resource model.

​

The gross investment in the Brook Mine property was $12 million as of December 31, 2025.

​

The Brook Mine initially produced representative mineralized material to serve as feedstock for testing, with the goal of demonstrating the viability of processing rare earth elements and critical minerals at a full-scale commercial facility and ultimately establishing mineral reserves and resources. Subject to the results of such testing, the Brook Mine is expected to produce a mix of refined rare earth element and other critical mineral products, as well as sub-bituminous thermal coal for domestic consumption.

​

We are unaware of any significant encumbrances to the Brook Mine.

​

Other Properties

​

Refer to the discussion of our *RAM Mine* under Item 1. “Business - Our Projects” for information about this property, which does not have any current coal resources or reserves and therefore is not included in the disclosures of mineral resources and reserves at December 31, 2025 to follow.

​

Notes:

- There is no certainty that any part of the Mineral Resources estimated will be converted into Mineral Reserves. Mineral Resources reported here are exclusive of Mineral Reserves. The point of reference for the coal resource is in-place.
- The assessment of reasonable prospects for economic extraction assumes coal resources amenable to underground mining methods have 2.0 feet minimum seam thickness, and those coal resources amenable to surface and highwall mines have a 1.0 foot minimum seam thickness, area mining with a cutoff stripping ratio of 20:1, and primarily metallurgical low and mid-volatile coal at the Berwind Complex realizing a sales price of $169 per ton at a cash cost of $101 per clean ton (FOB Mine), primarily metallurgical mid and high-volatile coal at the Knox Creek Complex realizing a sales price of $184 per ton and cash cost of $99 per clean ton (FOB Mine), primarily metallurgical high-volatile A and high-volatile B coal at the Elk Creek Complex realizing a sales price of $131 per ton at a cash cost of $77 per clean ton (FOB Mine), and primarily metallurgical low-volatile coal at the Maben Complex realizing a sales price of $153 per ton and cash cost of $116 per clean ton (FOB Mine) based on their respective TRS reports, which can be found in the Exhibits.
- For each complex, the time frame over which the coal sales price is assumed is the life of mine, which is: 20 years for the Berwind Complex; 30 years for the Knox Creek Complex; 15 years for the Elk Creek Complex; and 15 years for the Maben Complex.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

​

Notes:

- Coal and the rare earths and other critical minerals resources are considered collectively in the evaluation of reasonable prospects of economic extraction with estimated revenues as follows: $850/kg Dy2O3, $770/kg Ga2O3, $2,435/kg GeO2, $130/kg Nd2O3, $130/kg Pr6O11, $3,750/kg Sc2O3, $3,000/kg Tb4O7, and $13.23/tonne thermal coal. The time frame over which the commodity prices were assumed was 40 years which represents the life of mine for the initial assessment supporting the mineral resources.
- Rare earth elements and other critical minerals processing recoveries are as follows: 82% Dy2O3, 67% Ga2O3, 94% GeO2, 92% Nd2O3, 92% Pr6O11, 70% Sc2O3, 94% Tb4O7. An overall recovery of 90 percent was applied to the thermal coal.
- Open pit mining methods are assumed with mining costs of $1.33 per tonne used for resource constraining pit shell generation. A mining cost adjustment factor (MCAF) of 0.90 was used for rare earths and other critical minerals and waste rock types to account for the 45X production tax credit assumed.
- A Net Smelter Return (NSR) marginal rare earths and other critical minerals cutoff of $67.69 per metric tonne of rock was used to classify the rare earths and other critical mineral resources as an Inferred Mineral Resource within the optimized pit shell. The marginal rare earths and other critical minerals cutoff consists of $69.80 per tonne of processing costs, $1.44 per tonne of G&A and $3.97 per tonne of rare earths and other critical minerals residue handling costs as well as an offset to the costs of 10 percent (-$7.52 per tonne) from the 45X production tax credit. *NSR* = (69.80 + 1.44 + 3.97) × (1 − 10%)
- Rare earths and other critical mineral resources were constrained within a revenue factor 1.0 pit shell.
- The point of reference for the mineral resources is in-place.
- Resource tonnes and contained metal oxide tonnes are metric.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

- Coal and the rare earths and other critical minerals resources are considered collectively in the evaluation of reasonable prospects of economic extraction with estimated revenues as follows: $850/kg Dy2O3, $770/kg Ga2O3, $2,435/kg GeO2, $130/kg Nd2O3, $130/kg Pr6O11, $3,750/kg Sc2O3, $3,000/kg Tb4O7, and $13.23/tonne thermal coal. The time frame over which the commodity prices were assumed was 40 years which represents the life of mine for the initial assessment supporting the coal resources.
- Rare earth elements and other critical minerals processing recoveries are as follows: 82% Dy2O3, 67% Ga2O3, 94% GeO2, 92% Nd2O3, 92% Pr6O11, 70% Sc2O3, 94% Tb4O7. An overall recovery of 90 percent was applied to the thermal coal. The point of reference for the coal resource is in-place.
- Open pit mining methods are assumed and mining costs of $1.33 per tonne were used for resource pit shell generation. A mining cost adjustment factor (MCAF) of 0.90 was used for targeted critical mineral and waste rock types to account for the 45X production tax credit assumed.
- The effective marginal cutoff for coal resources is $0.05/tonne consisting of coal selling costs. Coal is sold as run of mine product, and no additional processing is planned.
- A minimum seam thickness of two feet and the revenue factor 1.0 pit shell was used to constrain the coal Inferred Resources.
- Resource tonnes are metric.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

Notes:

- Clean coal reserve tonnage based on underground mining recovery of 50 to 80 percent (contingent upon retreat mining capability), 90 percent for surface mining, 40 percent for highwall mining, theoretical preparation plant yield, and a 95 percent preparation plant efficiency. The point of reference is after preparation plant.
- Mineral Reserves estimated for the Berwind Complex are based primarily on metallurgical low and mid-volatile coal realizing a sales price of $169 per ton at a cash cost of $101 per clean ton (FOB Mine), primarily metallurgical mid and high-volatile coal at the Knox Creek Complex realizing a sales price of $184 per ton and cash cost of $99 per clean ton (FOB mine), primarily metallurgical high-volatile A and high-volatile B coal at the Elk Creek Complex realizing a sales price of $131 per ton at a cash cost of $77 per clean ton (FOB Mine), and primarily metallurgical low-volatile coal at the Maben Complex realizing a sales price of $153 per ton and a cash cost of $116 per clean ton (FOB mine) based on their respective TRS reports, which can be found in the Exhibits.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

​

Our coal resource and reserve estimates at December 31, 2025, were prepared by a qualified person (“QP”) and have a basis in periodic, historical reserve studies completed by third-party geological engineering firms. Our coal resource and reserve estimates are based on data obtained from our drilling activities and other available geologic data. Acquisitions or sales of coal properties will change these estimates. Changes in mining methods or the utilization of new technologies may increase or decrease the recovery basis for a coal seam. The most recent studies of our coal reserves for the Elk Creek Complex, Berwind Complex, Knox Creek Complex, and Maben Complex were prepared by an independent engineering firm, Weir. In periods between third party updates, we update reserves utilizing our internal staff of engineers and geologists based on production data. We intend to continue to periodically retain outside experts to assist management with the verification of our estimates of our coal reserves going forward.

​

Weir prepared our mineral (coal) reserve reporting in compliance with the Regulation S-K Subpart 1300 requirements. Weir initiated this process with us by completing a historical project review as well as its validation of our complete drill hole database. Weir validated that property control is accurately reflected in mineral reserve modeling, verifying the latest property boundaries, including control by each seam. Weir also examined mineral reserve boundaries to ensure agreement with mining parameters, such as minimum thickness, minimum yield and minimum inter-burden between seams. Mineral resource classification is determined based on the expectation of our meeting these mining parameters. Weir also conducted mining integrity checks to ensure each mineral reserve area is minable.

​

In determining whether our mineral reserves meet this standard, we take into account, among other things, our potential ability to obtain a mining permit, the possible necessity of revising a mining plan, changes in estimated future costs, changes in future cash flows caused by changes in costs required to be incurred to meet regulatory requirements and obtaining or renewing mining permits, variations in quantity and quality of coal, and varying levels of demand and their effects on selling prices. Further, the economic recoverability of our reserves is based on market conditions including contracted pricing, market pricing and overall demand for our coal. Thus, the actual value at which we no longer consider our reserves to be economically recoverable varies depending on the length of time in which the specific market conditions are expected to last. We consider our reserves to be economically recoverable at a price in excess of our cash costs to mine the coal and fund our ongoing replacement capital.

​

Summaries of the mineral resources and mineral reserves as of December 31, 2025 and December 31, 2024 are shown below. Weir employees served as the QP and prepared the estimates of mineral resources and mineral reserves at the Berwind Complex, Knox Creek Complex, Elk Creek Complex, and Maben Complex. Since a material change has not occurred from the last TRS filed for each of the Berwind, Knox Creek, Elk Creek, and Maben complexes, the previous years’ TRSs have not been updated. Refer to Exhibit 96.1, 96.2, 96.3, and 96.4 for access to the previous TRS for the Berwind Complex, Knox Creek Complex, Elk Creek Complex, and Maben Complex, respectively.

​

Estimates of coal reserves and resources are updated annually to reflect changes resulting from active mine production, mine plan modifications, property acquisitions/sales, impacts of additional exploration drilling, and any other changes that impact remaining coal reserve and resource tonnage.

​

The combined proven and probable reserves increased by 19 million tons and measured and indicated in-place resources decreased by 15 million tons during 2025, which was driven by previously classified resources at the Maben Complex being classified as reserves based on the latest assessments.

​

Additional details on the key assumptions and parameters relating to the mineral resources and mineral reserves are discussed in sections 11 and 12, respectively, of each TRS.

​

**Internal Controls**

​

In our exploration and mineral resource and reserve estimation efforts, we utilize a certified American National Standards Institute third-party laboratory, which has in-house quality control and assurance procedures. Once in possession of the samples, the laboratory standard sample preparation and security procedures are followed. After the sample has been tested, reviewed, and accepted, the disposal of the sample is done in accordance with local, state and EPA approved methods.

​

Weir has determined the sample preparation, security and analysis procedures used for our drillhole samples meet current coal industry standards and practices for quality testing, with laboratory results suitable to use for geological modeling, mineral resource estimation and economic evaluation.

​

Year-end reserve estimates are and will continue to be reviewed by our Chief Executive Officer and other senior management, and revisions are communicated to our board of directors. Inaccuracies in our estimates of our coal reserves could result in decreased profitability from lower-than-expected revenue or higher-than-expected costs. Actual production recovered from identified reserve areas and properties, and revenue and expenditures associated with our mining operations, may vary materially from estimates.

​

## Item 3. Legal Proceedings

Due to the nature of our business, we may become, from time to time, involved in routine litigation or subject to disputes or claims related to our business activities. In the opinion of our management, there are no pending litigation, disputes or claims against us which, if decided adversely, will have a material adverse effect on our financial condition, cash flows or results of operations. For a description of our legal proceedings, see Note 9—Commitments and Contingencies in Item 8, Part II.

## Item 4. Mine Safety Disclosures

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this Annual Report.

PART II

## Item 5. Market for Registrant’s Common Equity and Related Shareholder Matters

On June 12, 2023, an amendment to our amended and restated certificate of incorporation was approved by shareholder vote to reclassify the Company’s existing common stock as shares of Class A common stock, par value $0.01 per share, and create a separate Class B common stock having a par value of $0.01 per share.

The initial distribution of Class B common stock occurred on June 21, 2023 via a stock dividend to existing holders of common stock as of May 12, 2023. On the date of initial distribution, each holder of common stock received 0.2 shares of Class B common stock for every one share of existing common stock held on the record date.

*Market Information.* Our Class A and Class B common stock are listed on the NASDAQ Global Select Market under the symbols “METC” and “METCB,” respectively. Our 8.375% Senior Notes due 2029 and 8.250% Senior Notes due 2030 are listed on the NASDAQ Global Select Market under the symbols “METCZ” and “METCI,” respectively.

*Holders.* As of the close of business on February 25, 2026, there were 88 holders of record of our Class A common stock and 91 holders of record of our Class B common stock. Because many of our common shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these holders of record.

*Dividends.* On December 5, 2024, the Company announced that the Board of Directors declared a quarterly stock dividend of $0.1375 per share of Class A common stock to be payable on March 14, 2025 to shareholders of record as of February 28, 2025. Class A holders received 0.015537 of one share of Class B common stock for each share of Class A common stock held on the record date which was determined by dividing $0.1375 by the February 28, 2025 Class B closing price of $8.85.

On February 18, 2025, the Company announced that the Board of Directors declared a quarterly cash dividend of $0.1971 per share on the Company’s Class B common stock. The first quarter dividend was paid on March 14, 2025, to shareholders of record on February 28, 2025.

On March 17, 2025, the Company announced that the Board of Directors declared a reduced quarterly stock dividend of $0.06875 per share of Class A common stock to be payable on June 13, 2025 to shareholders of record as of May 30, 2025. Class A holders received 0.009228 of one share of Class B common stock for each share of Class A common stock held on the record date which was determined by dividing $0.06875 by the May 30, 2025 Class B closing price of $7.45.

On May 12, 2025, the Company announced that the Board of Directors declared a quarterly cash dividend of $0.1811 per share on the Company’s Class B common stock. The second quarter dividend was paid on June 13, 2025, to shareholders of record on May 30, 2025.

At the July 2025 Board meeting, the decision was made to suspend the quarterly Class A stock dividend.

On August 22, 2025, the Company announced that the Board of Directors declared a quarterly stock dividend of $0.1918 per share on the Company’s Class B common stock to be payable on September 19, 2025 to shareholders of record on September 5, 2025. Class B holders received 0.011988 of one share of Class B common stock for each share of Class B common stock held on the record date which was determined by dividing $0.1918 by the September 5, 2025 Class B closing price of $16.00.

On November 14, 2025, the Company announced that the Board of Directors declared a quarterly stock dividend of $0.1780 per share on the Company’s Class B common stock to be payable on December 19, 2025 to shareholders of record on December 5, 2025. Class B holders received 0.014390 of one share of Class B common stock for each share of Class B common stock held on the record date which was determined by dividing $0.1780 by the December 5, 2025 Class B closing price of $12.37.

All dividends declared for holders of Class B common stock were based on 20% of CORE royalty and infrastructure fees for the previous quarter.

Subsequent to the date of the financial statements, the Company announced that the Board of Directors declared a stock dividend of $0.1489 per share on the Company’s Class B common stock to be payable on March 27, 2026 to shareholders of record on March 13, 2026. Given that this payment will occur in the form of Class B shares, Class B holders will receive a number of shares of Class B common stock for each share of Class B common stock determined by dividing $0.1489 by the closing transaction price of the Class B common stock on March 13, 2026.

The Company anticipates distributing quarterly dividends in the future; however, it is currently unknown whether cash or non-cash dividends will be declared for Class A and Class B shareholders in future periods, as future declarations of dividends are subject to Board of Directors’ approval and may be adjusted as business needs or market conditions change. In addition, the Board of Directors retains the power to change or add expense allocation policies related to CORE, redefine CORE assets, and redetermine CORE’s per-ton usage fees at any time without shareholder approval.

*Equity Compensation Plans*. The Company does not have any non-stockholder approved equity compensation plans.

*Stock Repurchases*. The Company routinely allows employees to surrender common stock that would be issuable upon the vesting or exercise of stock-based compensation awards to pay estimated taxes. The value of common stock surrendered by employees is determined based on the price of the Company’s common stock at the time of relinquishment. During the quarter and year ended December 31, 2025, there were no repurchases of common shares previously issued.

In December 2025, the Board of Directors authorized the repurchase of up to $100 million of Company's Class A common stock over a period of 24 months (“2025 Stock Repurchase Program”). Under the 2025 Stock Repurchase Program, the Company may repurchase shares through open market purchases, privately-negotiated transactions, block purchases or otherwise. The Board of Directors also authorized the Company to enter into written trading plans under Rule 10b-18 of the Exchange Act with a third-party broker to facilitate the repurchase of its Class A common stock pursuant to the 2025 Stock Repurchase Program. As of December 31, 2025, the Company had not repurchased any shares under the 2025 Stock Repurchase Program.

Overview

The Company is an operator and developer of high-quality, low-cost metallurgical coal in southern West Virginia, and southwestern Virginia and is exploring a coal, rare earth and other critical minerals project in Wyoming. Our metallurgical coal development portfolio primarily includes the following properties: Elk Creek, Berwind, Knox Creek, and Maben. We believe each of these properties possesses geologic and logistical advantages that make our coal among the lowest delivered-cost U.S. metallurgical coal to our domestic customer base, North American blast furnace steel mills and coke plants, as well as to international metallurgical coal consumers. In mid-2025, we held a ribbon cutting and groundbreaking event at our rare earth element and critical mineral exploratory property near Sheridan, Wyoming (the Brook Mine). The Brook Mine is currently an exploration stage property with respect to its rare earth element and critical mineral operations. The Brook Mine initially produced representative material to serve as feedstock for testing, with the goal of demonstrating the viability of processing rare earth elements and critical minerals at a full-scale commercial facility and ultimately establishing mineral reserves and resources. There is no assurance that we will be able to successfully develop the Brook Mine into a commercial scale mine, and there is no certainty that any part of the inferred mineral resources estimated will be converted into mineral reserves in the future. Contiguous to the Brook Mine,

the Company operates a carbon research facility related to the production of advanced carbon products and materials from coal.

Our reportable segments, which are primarily based on the Company’s internal organizational structure and types of controlled mineral deposits, are its two operating segments—Metallurgical Coal and Rare Earths and Critical Minerals. Where applicable, prior period amounts have been recast to conform to this segment reporting structure, which was modified during the third quarter of 2025.

Metallurgical Coal Segment

Our primary source of revenue is the sale of metallurgical coal. We maintain 85 million reserve tons and 1,337 million measured and indicated resource tons of high-quality metallurgical coal. Our plan is to continue the development of our existing properties and grow annual production over the next few years to possibly as much as seven million clean tons of metallurgical coal annually, subject to market conditions, permitting and additional capital deployment in the medium-term. We may also acquire additional reserves or infrastructure that contribute to our focus on advantaged geology and lower costs.

The overall outlook of the metallurgical coal business is dependent on a variety of factors such as pricing, regulatory uncertainties, and global economic conditions. Coal consumption and production in the U.S. are driven by several market dynamics and trends including the U.S. and global economies, the U.S. dollar’s strength relative to other currencies and accelerating production cuts. Blast furnace steelmaking is more prevalent outside the U.S. compared to domestic steel production, which creates demand for exports of metallurgical coal, including demand growth in Asia Pacific.

Global metallurgical coal markets softened in 2024 and continued to do so in 2025 due to constrained economic growth in some regions of the world and continued conflict overseas. The global steel market experienced slower growth, especially in China, resulting in elevated levels of Chinese steel exports. These conditions have led steel companies to both cut back on their own production and to reduce the price they are willing to pay for their metallurgical coal feedstock. Overall steel demand will likely remain weak in the near term; however, supply cuts may occur for higher cost operations absent a significant upward movement in pricing. Longer term, the Company believes that limited global investment in new coking coal production capacity, the industrialization of emerging economies, expansion of urbanization globally, and an eventual return to economic growth will support coking coal markets overall.

During the year ended December 31, 2025, we sold 3.8 million tons of coal and recognized $536.6 million of revenue. Of this amount, 37% of our revenue was from sales into North American markets, including Canada, and 63% of our revenue was from sales into export markets. During the same period of 2024, we sold 4.0 million tons of coal and recognized $666.3 million of revenue, of which 33% was from sales into North American markets, including Canada, and 67% was from sales into export markets. Sales into export markets, which often include index-based pricing, generally have greater exposure to variability in pricing from period to period. The Company’s exports have not been materially delayed or otherwise affected by recent severe weather events, dockworker labor disputes, or recently enacted U.S. tariffs.

As of December 31, 2025, the Company had outstanding performance obligations of 1.1 million tons for contracts with fixed sales prices averaging $142 per ton, excluding freight, as well as 1.2 million tons for contracts with index-based pricing mechanisms. The Company expects to satisfy approximately 97% of the committed tons in 2026 and the remainder in 2027. Refer to Note 10—Revenues in Item 8, Part II for additional information.

The metallurgical coal markets are volatile in nature; therefore, the Company prioritizes managing its financial position and liquidity, while managing costs and capital expenditures and returning value to its shareholders.

In 2025, our segment capital expenditures were $60.5 million, excluding capitalized interest of $1.2 million. In 2024, our capital expenditures were $69.7 million, excluding capitalized interest of $1.5 million. The decrease in capital expenditures was due to lower spending in 2025 on the Company’s strategic growth projects, specifically at the Maben preparation plant.

The Company produced 3.8 million tons in 2025 compared to 3.7 million tons in 2024 as a result of the increase in capacity and completed development work.

Rare Earths and Critical Minerals Segment

Our ongoing business development efforts are focused on the timely and prudent advancement of our rare earth elements and critical minerals operations, the establishment of associated processing facilities and the production of rare earth element minerals and coal-to-carbon based products and critical minerals products.

​

We plan to target the processing and production of a number of rare earth elements and critical minerals which include heavy magnetic rare earth elements, like terbium and dysprosium, and critical minerals, like gallium, germanium and scandium which are, from time to time subject to strict export licensing requirements and changing destination-specific restrictions (including export bans or restrictions to the United States) imposed by the Chinese government. These planned initiatives provide substantial growth opportunities in future periods.

​

In 2023, we announced the discovery of a major deposit of primary magnetic rare earth elements and critical minerals at our mine, the Brook Mine near Sheridan, Wyoming. The Brook Mine rare earth elements and critical minerals site has what we believe to be the largest unconventional deposit of rare earth elements and critical minerals discovered to date in the United States, as well as the first new rare earth elements mine in the United States in 70 years. We had a ribbon cutting and groundbreaking at the Brook Mine in July 2025 and the overall advancement of this mine and processing project is ongoing.

​

Since the July groundbreaking of the Brook Mine, we have rapidly moved to build on this momentum to transition into what we believe will be the nation’s first dual platform critical minerals company focused on both metallurgical coal and rare earth elements and other critical minerals.

​

Contiguous to the Wyoming mine, we operate a carbon research facility called the iCAM Research Center which is related to the production of high value advanced carbon products and materials from coal. In connection with these activities, we hold a body of more than 70 intellectual property patents and pending applications, exclusive licensing agreements and various trademarks.

​

To support the expansion of our rare earth elements and critical minerals operations, we plan to actively engage with federal and state officials to expand the existing approved Brook Mine permit covering roughly 4,500 acres to include our entire approximately 15,800 acres of control. Our commercial processing facility will be similarly designed to increase its processing capacity and accommodate higher levels of production.

​

Before advancing to a full-scale commercial plant, we will test various processes at a pilot facility to be located at the Brook Mine site near our iCAM Research Center outside Sheridan. In addition, we received a $6.1 million matching grant from the Wyoming Energy Authority’s Energy Matching Fund to be applied toward development of the pilot facility.

​

Based on pilot testing results, we expect to proceed to engineering and designing the full commercial plant, with a construction period to be validated and updated upon the completion of a pre-feasibility study to be followed by a subsequent two-year shakedown period for the plant to be optimized to reach full steady-state capacity.

​

We will also continue advancing geological work to refine our understanding of the deposit, with targeted infill drilling to tighten spacing, enhance grade control, and improve resource classification. We are also engaged in expansion drilling outside the existing permit boundary and into deeper formations.

​

On September 17, 2025, we received a new geological TRS from Weir, updated from the March 2025 study. As a result, management has undertaken a revised mine plan designed around a higher cutoff concentration grade for the Brook Mine deposit. The Brook Mine represents a geologically unique rare earth elements deposit located along the northwestern margin of the Powder River Basin. Stratigraphy in the area is steeply dipping and intersected by multiple

fault and fracture systems, which likely facilitated secondary mobilization and concentration of rare earth elements via fluid flow, enriching favorable coal and associated carbonaceous materials. Given these factors, similar rare earth element grades are not expected to be repeatable elsewhere within the Powder River Basin.

​

While current drilling and core sampling have focused within our initial 4,500-acre permitted area, we control and own all coal and other minerals on an additional roughly 11,500 acres of contiguous land. Historic lithologic and wireline logs suggest these areas share similar geologic characteristics. Multiple high-grade assay results near the existing permit boundary reinforce the expectation that rare earth elements mineralization extends beyond the current permitted area.

​

To support our transition and growth plans, in July 2025, the Company issued $65.0 million aggregate principal amount of our 2030 Senior Notes and, in early August 2025, we raised approximately $200.0 million from an offering of our Class A common stock (before deducting underwriting discounts and commissions and other offering expenses payable by the Company). Subsequently, in November 2025, the Company issued $345.0 million aggregate principal amount of our 2031 Convertible Senior Notes, and in December 2025, the Company entered into a Third Amended and Restated Credit and Security Agreement that increased our available revolving credit commitments to $500 million (comprising an initial $350 million asset based revolving commitment plus a $150 million incremental accordion feature) and extended the stated maturity of the credit facility to December 30, 2030 (subject to a springing maturity tied to convertible indebtedness). The commitments under the previous Revolving Credit Agreement were $200 million with a $75 million accordion feature. We believe these capital raises and increased liquidity have positioned us to more effectively implement our planned evolution into a dual platform critical minerals company.

​

The timeline to production and expanded production for our rare earth elements and critical minerals initiatives is subject to obtaining all required federal, state, and local permits and licenses and complying with applicable regulatory requirements, as the project is designed and developed without encountering unforeseen delays. Critical mineral production, including mill throughput and feed grades, is subject to further technical validation, including additional infill and step-out drilling, geological modeling, mine planning, and metallurgical testing. We intend to pursue these activities in parallel with our ongoing development plans to support the timely and prudent advancement of the Brook Mine and associated processing facilities.

​

We have also made notable additions to our executive management team in 2025 to lead in the development of the Rare Earths and Critical Minerals segment as we continue to refine mineral recovery, extraction methodology, and processing capacity assumptions within the mine plan and flowsheet. To assist in the continued development of the project, the Company has officially retained Hatch Ltd. to lead its ongoing pre-feasibility study. Hatch was selected for its technical expertise in rare earth element processing and will oversee test work, pilot plant design, and process optimization. This pre-feasibility study is expected to provide key information for future permitting, investment, and offtake discussions aligning with the Company’s strategy to accelerate project development.

​

Recently, the Company has developed a fundamental alternative flowsheet design for the processing of potential rare earth elements and critical minerals from coal deposits. This process is both proprietary and patent-pending and has been developed by our new internal critical minerals processing team. This design improves upon the solvent extraction processing techniques previously modeled. Independent third-party testing, design, optimization and preparation of the change in flowsheet design are in process. As part of this new flowsheet analysis, Hatch is expected to provide a pilot plant re-design of the interior infrastructure of the pilot plant. The subsequent more detailed pre-feasibility study, also being prepared by Hatch, is now expected for completion by late 2026.

​

In the fourth quarter of 2025, the Company announced an initiative to establish a Strategic Critical Minerals Terminal ("SCMT") at the Brook Mine. This initiative is being pursued to help the private and public sector overcome supply chain risks and ensure uninterrupted access to strategic materials. The SCMT is designed to position us to become a comprehensive, vertically integrated upstream producer of critical minerals and rare earth elements in the United States. The SCMT is expected to provide long-term strategic stockpiling, storage, and inventory management solutions for our potential broad basket of critical minerals and rare earths. Any future stockpiling, storage, or inventory management activities at or related to the Brook Mine will depend upon, and cannot precede, the successful completion

of exploration activities and subsequent studies and determinations required under Subpart 1300, and there is no assurance that we will establish mineral reserves or reach commercial-scale production.

​

During 2025, our segment capital expenditures were $4.5 million compared to $0.2 million in 2024. The increase in capital expenditures was attributable to the continued expansion of the Brook Mine project.

No revenues have been recognized from the Company’s Rare Earths and Critical Minerals segment to date.

The activities at the Brook Mine may result in a material change to our operating results and financial condition in future periods as the project continues to develop. The future financial statement impact is largely dependent on the development activities described above and the subsequent achievement of commercial production. At this time, we are unable to estimate the potential financial impact to future periods.

​

Net income and Adjusted EBITDA were negatively impacted by the softening of global metallurgical coal markets and the decrease in metallurgical coal price indices. This occurred due to a variety of macroeconomic factors, including the continued Chinese oversupply of steel into a muted global economic environment.

*Refer to *Non-GAAP Financial Measures* below for an explanation of the Company’s calculation of Adjusted EBITDA.

Year Ended December 31, 2025 compared to Year Ended December 31, 2024

Our revenue includes sales to customers of Company-produced coal as well as smaller amounts of coal purchased from third parties. We include amounts billed by us for transportation to our customers within revenue and transportation costs incurred within cost of sales.

*Revenue*. Coal sales for the full-year 2025 were $536.6 million, approximately 19% lower than the same period in 2024 driven by the negative impact of pricing and a 4% decrease in tons sold. See the “Metallurgical Coal Segment” section below for further discussion of year-over-year changes in revenue. There are no revenues from rare earth elements and critical minerals at this time.

Refer to Note 2—Summary of Significant Accounting Policies—Concentrations and Note 10—Revenues in Item 8, Part II for additional information regarding sales to customers.

*Cost of sales.* Our cost of coal sales for the full-year was $453.4 million, approximately 15% lower than the same period in 2024 driven by the closure of the Jawbone mine in Q3 2024 and the idling of the Rockhouse Eagle mine and Laurel Fork mine in 2025. In addition, trucking costs were reduced at the Maben complex subsequent to commissioning in Q4 2024. See the “Metallurgical Coal Segment” section below for further discussion of year-over-year changes in cost of sales. There are no cost of sales from rare earth elements and critical minerals at this time.

*Asset retirement obligation accretion*. ARO accretion was $1.7 million for 2025 and was 14% higher than 2024 driven by an increase in asset retirement obligations incurred during the year.

*Depreciation, depletion, and amortization*. Depreciation, depletion, and amortization expense totaled $68.2 million in 2025 compared to $65.6 million in 2024. The increase in 2025 was due to the increases in plant and equipment and production versus 2024.

*Selling, general and administrative (“SG&A”) expenses*. SG&A expenses were $69.4 million for 2025 compared to $49.3 million for 2024. The increase in 2025 compared to 2024 was driven by an increase of approximately $9.1 million in professional service expenses, a $5.2 million increase in internal labor costs and $7.1 million in development costs which are each mainly attributable to the development of our rare earth element and critical minerals operations.

*Other income (expense), net.* Other income, net was $1.6 million in 2025 compared to $4.4 million in 2024. The net decrease in 2025 compared to 2024 is primarily driven by the $2.2 million recovery of previously incurred demurrage and other transportation-related matters in 2024, a $1.2 million lost coal recovery claim in 2024, and an actuarial gain of $0.5 million associated with the Company’s occupational disease benefit obligation in 2024 compared to a $0.2 million actuarial loss in 2025.

*Interest expense, net.* Interest expense, net was approximately $7.8 million in 2025 as compared to $6.1 million in 2024. The increase in net interest expense in 2025 was primarily due to the issuance of our Senior Notes due 2029 in late 2024.

*Income tax expense.* We recognized an income tax benefit of $10.7 million compared to an expense of $3.7 million in 2025 and 2024, respectively, driven by the decrease in income before taxes. Refer to Note 12—Income Taxes in Item 8, Part II for an explanation of differences versus the statutory rate of 21%.

​

Our revenue includes sales of Company-produced coal and coal purchased from third parties. We include amounts billed by us for transportation to our customers within revenue and transportation costs incurred within cost of sales.

Year Ended December 31, 2025 compared to Year Ended December 31, 2024

*Revenue.* Coal sales for the full-year 2025 were $536.6 million, approximately 19% lower than the same period in 2024 driven by the negative impact of pricing and a 4% decrease in tons sold. The decrease in tons sold is attributable to export markets, which decreased by 6% primarily due to timing differences in shipments to foreign customers. Revenue per ton sold decreased 16% from $167 per ton to $140 per ton while revenue per ton sold (FOB mine), a non-GAAP measure which excludes transportation revenues and demurrage, also decreased 14% from $140 per ton to $120 per ton. Refer to Non-GAAP Financial Measures later in Item 2 for more information regarding this measure. The decrease in the Company’s revenue per ton sold measures was driven by the variability in index-based pricing for export sales. We expect metallurgical coal prices to remain volatile in the near term.

*Cost of sales.* Our cost of coal sales for the full-year was $453.4 million, approximately 14% lower than the same period in 2024 driven by the closure of the Jawbone mine in Q3 2024 and the idling of the Rockhouse Eagle mine and Laurel Fork mine in 2025. In addition, trucking costs were reduced at the Maben complex subsequent to commissioning in Q4 2024. Cost of sales per ton sold decreased 11% from $132 per ton to $118 per ton. Cash cost per ton sold (FOB mine), a non-GAAP measure which excludes transportation costs and idle mine costs, decreased 7% from $105 per ton to $98 per ton. Mine costs in 2024 were impacted negatively by challenging geology and labor constraints which improved during 2025.

*Segment adjusted EBITDA.* Segment adjusted EBITDA for the full-year 2025 was $69.4 million, approximately 42% lower than the same period in 2024 driven by the revenue and cost of sales items discussed above.

Rare Earths and Critical Minerals Segment

As of December 31, 2025, the Company has not recorded any revenues or cost of sales from the Rare Earths and Critical Minerals segment. Segment Adjusted EBITDA is shown below:

| (In thousands) | Year ended December 31, 2025 | Year ended December 31, 2024 | Year ended December 31, / Increase (Decrease) |

Refer to Non-GAAP Financial Measures below for an explanation of the Company’s calculation of Segment Adjusted EBITDA. |  |  |  |

​

​

*Segment adjusted EBITDA.* Segment adjusted EBITDA for the full-year 2025 decreased by approximately $12.0 million compared to 2024 primarily driven by increased labor and professional service costs to develop the Brook Mine rare earth elements and critical minerals project in 2025.

Non-GAAP Financial Measures

Adjusted EBITDA. Adjusted EBITDA is used as a supplemental non-GAAP financial measure by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We believe Adjusted EBITDA is useful because it allows us to more effectively evaluate our operating performance.

We define Adjusted EBITDA as net income plus net interest expense; stock-based compensation; depreciation, depletion, and amortization expenses; income taxes; accretion of asset retirement obligations; and, when applicable, certain other non-operating and expense items that are non-recurring and not related to the underlying business performance. A reconciliation of net income to Adjusted EBITDA is included below. Adjusted EBITDA is not intended to serve as a substitute to U.S. GAAP measures of performance and may not be comparable to similarly-titled measures presented by other companies.

​

Non-GAAP revenue per ton sold. Non-GAAP revenue per ton sold (FOB mine) is calculated as coal sales revenue less transportation revenues and demurrage, divided by tons sold. We believe revenue per ton (FOB mine) provides useful information to investors as it enables investors to compare revenue per ton we generate against similar measures made by other publicly-traded coal companies and more effectively monitor changes in coal prices from period to period excluding the impact of transportation costs which are beyond our control. The adjustments made to arrive at these measures are significant in understanding and assessing our financial performance. Revenue per ton sold (FOB mine) is not a measure of financial performance in accordance with U.S. GAAP and, therefore, should not be considered as a substitute to revenue under U.S. GAAP.

​

Non-GAAP cash cost per ton sold. Non-GAAP cash cost per ton sold (FOB mine) is calculated as cash cost of sales less transportation, idle, and other costs, divided by tons sold. We believe cash cost per ton sold provides useful information to investors as it enables investors to compare our cash cost per ton against similar measures made by other publicly-traded coal companies and more effectively monitor changes in coal cost from period to period excluding the impact of transportation costs which are beyond our control. The adjustments made to arrive at these measures are significant in understanding and assessing our financial performance. Cash cost per ton sold (FOB mine) is not a measure of financial performance in accordance with U.S. GAAP and, therefore, should not be considered as a substitute to cost of sales under U.S. GAAP.

2026 Sales Commitments

As of December 31, 2025, we had entered into forward sales contracts for approximately 1.1 million tons to North American customers at an average fixed price of $142 per ton, excluding freight, and 1.2 million additional tons to

export customers priced against various benchmark indices. The Company expects to satisfy approximately 97% of these commitments in 2026 and the remainder in 2027. Sales commitments of another 0.8 million tons were obtained subsequent to December 31, 2025.

The annual contracting season with North American steel producers generally occurs in late-summer through the fall. As stated above, we had entered into forward sales contracts with certain North American customers at an average fixed price of $142 per ton, excluding freight, as of December 31, 2025. This is lower than the average fixed price of $152 per ton, excluding freight, that was obtained during the previous contracting season for North America.

Liquidity and Capital Resources

Our primary source of cash is proceeds from the sale of our coal production to customers and financing activities. Our primary uses of cash include the investment in the development of our rare earth elements and critical mineral platform, cash costs of coal production, capital expenditures, acquisitions, royalty payments, and other operating expenditures.

Cash flow information is as follows:

| (In thousands) | Years ended December 31, 2025 | Years ended December 31, 2024 | Years ended December 31, 2023 |
| --- | --- | --- | --- |
| Consolidated statement of cash flow data: |  |  |  |
| Cash flows from operating activities | $1,969 | $112,665 | $161,036 |
| Cash flows used in investing activities | (83,665) | (70,835) | (72,211) |
| Cash flows from (used in) financing activities | 489,041 | (50,788) | (82,517) |
| Net change in cash and cash equivalents and restricted cash | $407,345 | $(8,958) | $6,308 |

​

Cash flows provided by operating activities during 2025 decreased $110.7 million versus the prior year driven by lower cash earnings. Changes in operating assets and liabilities were unfavorable on a net basis by approximately $39.4 million compared to the prior year, which was driven by increases to inventory in the current year.

Net cash used for investing activities during 2025 increased by $12.8 million versus the prior year primarily due to land and mineral acquisitions of approximately $18.5 million in 2025, offset by $4.5 million lower capital expenditures in 2025 compared to 2024. The decrease in capital expenditures was due to the Company’s continued progress related to strategic growth projects and, therefore, the need for less growth capital expenditures.

Net cash from financing activities was $539.8 million higher in 2025 versus 2024, primarily due to approximately $398.5 million in long-term debt proceeds, net of $11.5 million in issuance costs, partially offset by $32.8 million of capped call purchases in conjunction with the Company’s convertible debt issuance during the period. The Company repaid $34.5 million in previously existing long-term debt during 2025. In 2024, the Company issued long-term debt resulting in net cash proceeds of $55.2 million and had net revolver repayments of 56.5 million. In addition, the Company completed a common stock offering during 2025 resulting in $189.0 million in cash inflows during the period and paid approximately $20.3 million less cash dividends in 2025 compared to 2024.

​

On June 21, 2023, the Company distributed Class B common stock, a tracking stock, to provide existing holders of the Company’s common stock an opportunity to participate directly in the financial performance of the Company’s CORE assets on a stand-alone basis, separate from the Company’s metallurgical coal operations. CORE assets were acquired initially by the Company as part of the Company’s acquisition of Ramaco Coal in the second quarter of 2022. The financial performance of CORE assets consists of the following non-cost-bearing revenue streams based on the Company’s current expectations:

- Royalty fees derived from the royalties associated with the Ramaco Coal and Amonate reserves, which we believe approximates 3% of Company-produced coal sales revenue excluding coal sales revenue from Knox Creek,
- Infrastructure fees based on $5.00 per ton of coal processed at our preparation plants and $2.50 per ton of loaded coal at the Company’s rail load-out facilities, and
- Future income derived, if and when realized, from rare earth elements, critical minerals, and advanced carbon products initiatives.

​

Dividends paid on the tracking stock allow the Company to return to Class B common stockholders a portion of the savings from royalties and infrastructure usage fees resulting from the acquisition of Ramaco Coal. In addition, the tracking stock provides an opportunity for Class B common stockholders to participate directly in the potential revenue growth associated with the development of carbon products and rare earth elements. Separate financial statements for CORE have not been included as exhibits to this filing since CORE’s financial performance and dividends will be evaluated based on non-cost-bearing revenue streams, at least initially, and other potential forms of passive income rather than reduced by allocated costs and expenses.

​

All dividends declared to date for Class B common stock were based on 20% of CORE royalty and infrastructure fees for the previous quarter.

Refer to Part II, Item 8, Note 15 for information regarding dividends declared subsequent to the date of the financial statements.

​

The Company anticipates declaring similar dividends on a quarterly basis in future periods; however, future declarations of dividends are subject to Board of Directors’ approval and may be adjusted as business needs or market conditions change.

Restricted cash balances at December 31, 2025 and December 31, 2024 were both $0.8 million and consisted of funds held in escrow for potential future workers’ compensation claims. Restricted cash balances were included in other current assets on the Consolidated Balance Sheets.

[Please see Part I, Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in our 2024 Annual Report on Form 10-K for a discussion of the Company’s cash flows for the year ended December 31, 2024 as compared to the year ended December 31, 2023.](https://www.sec.gov/Archives/edgar/data/1687187/000155837024003256/metc-20231231x10k.htm#Item7)

*Indebtedness*

At December 31, 2025, we had $467.5 million of outstanding debts, or $451.4 million net of unamortized issuance costs. Our indebtedness was comprised of $122.5 million of senior note debt ($116.6 million net of unamortized discounts and issuance costs), $345.0 million of convertible senior note debt ($334.8 million net of unamortized discounts and issuance costs), and less than $0.1 million debt related to various equipment loans. Of these amounts, less than $0.1 million is contractually due in 2026.

The Company’s net outstanding debt increased $363.2 million in 2025 due to the issuance of $65.0 million of 8.250% Senior Unsecured Notes due 2030 (the 2030 Senior Notes), offset by the repayment of $34.5 million of 9.00% Senior Unsecured Notes due 2026, and $345.0 million of 0.0% Convertible Senior Notes due 2031 (the 2031 Convertible Senior Notes). Revolver borrowings, which are typically used for the management of our normal operating cash position, were repaid in full at December 31, 2025.

The Company completed the public offering of 2030 Senior Notes on July 31, 2025 at an aggregate principal amount of $57.0 million with an option for the underwriters to purchase an additional $8 million of aggregate principal, which was exercised by the underwriters on August 1, 2025. The 2030 Senior Notes mature on July 31, 2030, unless redeemed prior to maturity and bear interest at a rate of 8.25% per annum, payable quarterly in arrears on the 30th day of January, April, July and October of each year, commencing on October 30, 2025. The Company may redeem the 2030 Senior Notes in whole or in part, at the Company’s option, at any time on or after July 31, 2027, or upon certain change of control events, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to, but not including, the date of redemption. Issuance-related costs for the 2030 Senior Notes included underwriters’ fees, attorney, accounting and filing costs totaling $3.5 million. The net proceeds were used to redeem all of the Company’s outstanding 9.00% Senior Notes Due 2026, with remaining proceeds to be used for general corporate purposes, including funding the acceleration of rare earth development, funding future investments, making capital expenditures, and funding working capital.

The Company completed the public offering of 2031 Convertible Senior Notes on November 4, 2025 at an aggregate principal amount of $300.0 million with an option for the underwriters to purchase an additional $45.0 million of aggregate principal, which was exercised by the underwriters on November 5, 2025. The 2031 Convertible Senior Notes do not bear regular interest and the principal amount does not accrete. The 2031 Convertible Senior Notes mature on November 1, 2031, unless earlier repurchased, redeemed or converted. Issuance-related costs for the 2031 Convertible Senior Notes included underwriters’ fees, attorney, accounting and filing costs totaling $10.5 million. Approximately $32.8 million of the net proceeds were used to fund the cost of entering into capped call transactions in conjunction with the issuance. We intend to use the remainder of the net proceeds to fund the development of our rare earth elements and critical minerals project, for strategic growth opportunities and for general corporate purposes.

Before August 1, 2031, noteholders will have the right to convert their 2031 Convertible Senior Notes only upon the occurrence of certain events. From and after August 1, 2031, noteholders may convert their 2031 Convertible Senior Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, shares of its Class A common stock or a combination of cash and shares of its Class A common stock, at the Company’s election. The initial conversion rate will be 30.5460 shares of the Class A Common Stock per $1,000 principal amount of 2031 Convertible Senior Notes, which represents an initial conversion price of approximately $32.74 per share of the Class A common stock.

The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. In addition, upon a Make-Whole Fundamental Change (as defined in the indenture governing the 2031 Convertible Senior Notes), the conversion rate may be increased for a specified period of time based on the trading price of the Company’s Class A common stock. The maximum increase to the conversion rate in such an event is 41.2371 shares per $1,000 principal amount, which results in up to approximately 14,226,800 additional shares if all 2031 Convertible Senior Notes are converted during such period and fully settled in shares.

The 2031 Convertible Senior Notes are redeemable, in whole or in part, at the Company’s option at any time on or after November 6, 2028, and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of the Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days during the 30 consecutive trading days ending on the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such redemption notice. In addition, calling (or the deemed calling of) any convertible note for redemption will constitute a Make-Whole Fundamental Change with respect to that convertible note, in which case the conversion rate will be increased in certain circumstances if it is converted after it is called for redemption.

In addition to the debts discussed above, the Company finances the payment of premiums associated with various insurance policies. The Company’s liability at December 31, 2025 was $4.0 million, which must be repaid in 2026.

The Company also has various finance leases for mining equipment, which generally include terms from three to five years. The Company’s total lease liability minimums for finance leases at December 31, 2025 was $19.1 million, which includes $7.7 million due in 2026 and $11.4 million due thereafter.

Refer to Note 6—Debt and Note 7—Leases in Item 8, Part II for additional information on indebtedness and leases.

In the normal course of business, we are a party to certain off-balance sheet arrangements, such as bank letters of credit and performance or surety bonds. Liabilities related to these arrangements are not reflected in Consolidated Balance Sheets, and we do not expect any material adverse effects on our financial condition, results of operations, or cash flows to result from these arrangements. We primarily use surety bonds to secure our financial obligations related to reclamation and other matters. Total surety bonds outstanding at December 31, 2025 were approximately $36.0 million.

Liquidity

The metallurgical coal markets are volatile in nature; therefore, the Company prioritizes managing its financial position and liquidity, while managing costs and capital expenditures and returning value to its shareholders.

On December 30, 2025, the Company entered into a Third Amended and Restated Credit and Security Agreement, which includes KeyBank National Association and multiple lending parties, in order to, among other things, extend the maturity date and increase the size of the facility. The amended facility has a maturity date of December 30, 2030 (subject to a springing maturity tied to convertible indebtedness), and provides an initial aggregate revolving commitment of $350.0 million as well as an accordion feature to increase the size by an additional $150.0 million subject to certain terms and conditions, including lenders’ consent. The amended facility provides the Company with additional flexibility to pursue further growth in production while meeting normal operating requirements. The terms of the amended facility also require the Company to maintain certain covenants, including fixed charge coverage ratio and compensating balance requirements. Borrowings under the amended facility may not exceed the borrowing base as determined under the amended formula included in the agreement.

At December 31, 2025, we had $440.3 million of cash and cash equivalents and $80.7 million of availability under our Revolving Credit Facility for future borrowings. Cash and cash equivalents include $7.5 million of compensating balances held in dedicated accounts to assure future credit availability under the revolver. The Company is party to an arrangement that began in 2023 whereby our cash and cash equivalents are placed at various banks in amounts no greater than the $250,000 FDIC-insured limit to help safeguard against potential losses in the financial sector. The Company’s total current assets were $597.6 million and were in excess of total current liabilities by $488.1 million as of the balance sheet date.  

The terms of the Revolving Credit Facility include covenants limiting the ability of the Company to incur additional indebtedness, make investments or loans, incur liens, consummate mergers and similar fundamental changes, make restricted payments, and enter into transactions with affiliates. The terms of the facility also require the Company to maintain certain covenants, including a fixed charge coverage ratio and compensating balance requirements. A fixed

charge coverage ratio of not less than 1.10:1.00 must be maintained by the Company during any period when excess availability is less than 12.5% of the maximum borrowing amount, tested as of quarter-end for the trailing four fiscal quarters. In addition, the Company must maintain an average daily cash balance of $5.0 million, as determined on a monthly basis, in a dedicated account as well as an additional $1.5 million and $1.0 million in separate dedicated accounts to assure future credit availability. At December 31, 2025, the Company was in compliance with all debt covenants under the Revolving Credit Facility.

​

As stated earlier, our primary use of cash includes our investment in the development of our rare earth elements and critical mineral platform, capital expenditures for mine development, infrastructure, and equipment as well as ongoing operating expenses. As of the date of this Annual Report, we expect to fund our capital and liquidity requirements for the next twelve months and the reasonably foreseeable future with cash on hand, borrowings under the Revolving Credit Facility, and projected cash flows from operations. Factors that could adversely impact our future liquidity and ability to carry out our capital expenditure program include the following:

- Project overruns related to the development of the Brook Mine, including but not limited to increased costs to extract and process rare earth elements and critical minerals into oxides and other products
- Timely delivery of our product by rail and other transportation carriers;
- Late payments of accounts receivable by our customers;
- Cost overruns in our purchases of equipment needed to complete our mine development plans;
- Delays in completion of development of our various mines, processing plants and refuse disposal facilities, which would reduce the coal we would have available to sell and our cash flow from operations; and
- Adverse changes in the metallurgical coal markets that would reduce the expected cash flow from operations.

​

If future cash flows were to become insufficient to meet our liquidity needs or capital requirements, due to changes in macroeconomic conditions or otherwise, we may reduce our expected level of capital expenditures for new mine production and/or fund a portion of our capital expenditures through the issuance of debt or equity securities, new debt arrangements, or from other sources such as asset sales.

On August 5, 2025, the Company filed an automatic shelf registration statement, which was effective upon filing, to sell any combination of Class A common stock, Class B common stock, preferred stock, depositary shares, debt securities, warrants, and rights. No securities may be sold until a prospectus supplement describing the method and terms of any future offering is delivered

*Working Capital*

Accounts receivable was $54.4 million at December 31, 2025, which declined $19.2 million versus December 31, 2024 driven by the $42.9 million decrease in fourth quarter revenues year over year. Inventories were $87.2 million at December 31, 2025, which were $43.8 million higher versus December 31, 2024 driven by increased production and decreased sales. Accounts payable were $41.6 million at December 31, 2025, down $7.3 million from December 31, 2024 due to variations in spending and the timing of vendor payments.

Capital Requirements

During 2025 we spent $64.3 million for capital additions, net of grant proceeds of $0.2 million, compared to $68.8 million during 2024. The decrease in 2025 was due largely due to the substantial progress made by the Company in achieving its initiatives to grow production.

We anticipate capital expenditures of approximately $85-90 million in 2026, which includes roughly $40 million of growth capital related to our commercialization efforts in Wyoming and the increase in production at our low volatile metallurgical coal complexes.

Contractual Obligations

The following table summarizes our significant contractual obligations at December 31, 2025:

| Line item | Payments due by period | Payments due by period | Payments due by period | Payments due by period | Payments due by period | Payments due by period | Payments due by period | Payments due by period | Payments due by period |

| Total | $ | $$536,186 | 22,247 | $ | $22,965 | $ | $132,655 | $ | $358,318 |

​

Minimum royalties represent the contractual minimum amounts to be paid monthly, quarterly or annually for  the right to access mineral properties and mine certain reserves and resources. The amounts are generally recoupable against future production royalties to be paid.

Refer to the previous discussion of *Indebtedness* above for additional information regarding the Company’s outstanding debt, insurance financing, and finance leases. Leases payments in the table above include payments for both financing and operating leases.

Take-or-pay obligations represent those liquidated damage obligations as determined by contract volume minimums for transportation of coal at the representative rates of transportation or a portion thereof. Additional take-or-pay commitments are currently in negotiation and are not reflected in the table above.

Asset retirement obligations have been excluded from the table above. Accounting for asset retirement obligations requires a number of estimates, including the amount and timing of payments to satisfy the obligation. The total liability recognized on the Company’s balance sheet for asset retirement obligations was $34.9 million at December 31, 2025. Refer to *Critical Accounting Policies and Estimates* below as well as Note 4—Asset Retirement Obligations in Item 8, Part II for additional information.

Estimated payments related to worker’s compensation and occupational disease obligations have also been excluded from the table above. Refer to *Critical Accounting Policies and Estimates* below for additional information related to these obligations. Refer also to Note 5—Accrued Liabilities and Other Liabilities in Item 8, Part II for additional information.

​

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the amounts of revenue and expenses reported for the period then ended.

*Coal Reserves*. Our coal reserves and resources are generally updated on an annual basis. There are numerous uncertainties inherent in estimating quantities and values of coal reserves and resources, including many factors beyond our control. As a result, estimates of coal reserves and resources are by their nature uncertain. Information about our reserves and resources consists of estimates based on engineering, economic, and geological data assembled by third-party qualified persons. Information used to determine recoverable reserves and resources include geological conditions, historical production from the area compared with production from other producing areas, assumed effects of regulations and taxes by governmental agencies, assumptions governing future prices, and future operating costs. Each of these may in fact vary considerably from the assumptions used in estimating reserves and resources. For these reasons, estimates of

economically recoverable quantities of coal attributable to a particular group of properties, and classification of these reserves and resources based on risk of recovery and estimates of future net cash flows, may vary substantially. Actual production, revenues, and expenditures with respect to reserves and resources will likely vary from estimates and these variances may be material. Variances could affect our projected future revenues and expenditures, valuation of coal reserves and resources, and amortization and depletion of mine development costs and mineral rights.

*Asset Retirement Obligations*. We initially recognize as a liability an asset retirement obligation, or ARO, associated with the retirement of a tangible long-lived asset in the period in which it is incurred or a reasonable estimate of fair value can be made, with an associated increase in the carrying amount of the related long-lived asset. The initially recognized asset retirement cost is amortized using the same method and useful life as the long-lived asset to which it relates. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. The liability is reduced as the reclamation work is performed and the related costs are applied.

Estimating the ARO requires management to make estimates and judgments regarding timing and existence of a liability, as well as what constitutes adequate restoration. Inherent in the fair value calculation are numerous assumptions and judgments including the ultimate costs, inflation factors, credit-adjusted discount rates, and the timing of the related cash flows. On at least an annual basis, we review our ARO liabilities and make necessary adjustments for significant increases in disturbed acreage, mining permit changes, significant mine plan revisions, and changes in cost estimates or timing of performance. To the extent future revisions are made to the ARO liability, a corresponding adjustment is made to the related asset.

If our assumptions differ from actual experience, or if changes in the regulatory environment occur, our actual cash expenditures and costs that we incur could be materially different than currently estimated.

*Occupational Disease (Pneumoconiosis) Obligations*. We recognize as a liability to provide for occupational illness (pneumoconiosis) benefits to eligible employees, former employees and dependents as required by the Mine Act. The occupational illness benefit obligation represents the present value of the actuarially computed liabilities for such benefits over the employees’ applicable years of service.

Estimating the future occupational disease (pneumoconiosis) benefits requires management to make estimates and judgments regarding timing and existence of a liability utilizing third-party actuaries to assist in preparing what constitutes adequate liability amounts. Inherent in the calculation are numerous assumptions and judgments including the ultimate costs, mortality factors, credit-adjusted discount rates, and timing of settlement. These estimates are subject to uncertainty due to a variety of factors, including limited Ramaco-specific claim volume, developments regarding medicine and treatment, and future cost trends. As a result, volatility in future estimates may occur and actual costs could differ significantly from the estimated amounts. The Company recognized a $0.2 million actuarial loss in the fourth quarter of 2025 due in part to a 0.3% decrease in the discount rate assumption.

*Impairment of Long-lived Assets.* We review our held-and-used long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which are generally at the mine level or at the mining complex level for mines that share infrastructure and/or developed access.

Events and circumstances that may trigger a recoverability assessment include, but are not limited to, a current expectation that a long-lived asset will be disposed of significantly before the end of its previously estimated useful life, a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in the physical condition of the asset(s), and an accumulation of costs significantly in excess of the amount originally expected. We generally do not view short-term declines in metallurgical coal prices as a triggering event for conducting impairment tests because of historic price volatility. In addition, a temporary idling of operations at a particular mine or complex may or may not be viewed as a triggering event depending on the remaining life of the mine, the length of time the mine is expected to be idle, and the amount of incremental costs expected to resume operations.

When events or changes in circumstances occur that trigger a recoverability test, the test is performed by comparing projected undiscounted cash flows from the use and eventual disposition of an asset or asset group to its carrying amount. If the projected undiscounted cash flows are less than the carrying amount, an impairment loss is recorded for the excess of the carrying amount over the estimated fair value of the asset or asset group, if any.

We make various assumptions, including assumptions regarding future cash flows in our assessments of long-lived assets for impairment. The assumptions about future cash flows and growth rates are based on the current and long-term business plans related to the long-lived assets.

*Income Taxes.* We are required to estimate the amount of tax payable or refundable for the current year and the deferred income tax liabilities and assets for future consequences of events that have been reflected in our financial statements or tax returns for each tax paying jurisdiction in which we operate. This process requires management to make judgments regarding the timing and probability of the ultimate tax impact of various agreements and transactions. We initially recognize the effects of a tax position when it is more than 50% likely, based on the technical merits that the position will be sustained upon examination. Our determination of whether or not a tax position has met the recognition threshold depends on the facts, circumstances, and information available at the reporting date.

We provide for deferred income taxes for temporary differences arising from differences between the financial statement and tax basis of assets and liabilities existing at each balance sheet date using enacted tax rates. A valuation allowance may be recorded to reflect the amount of future tax benefits that management believes are not likely to be realized. The assessment takes into account expectations of future taxable income or loss, available tax planning strategies and the reversal of temporary differences. The development of these expectations involves the use of estimates such as production levels, operating profitability, timing of development activities and the cost and timing of reclamation work. If actual outcomes differ from our expectations, we may record an additional valuation allowance through income tax expense in the period such determination is made. The Company had no valuation allowance at December 31, 2025.

Actual income taxes could vary from the estimates and judgments above due to future changes in income tax law, significant changes in the jurisdictions in which we operate, our ability to generate sufficient future taxable income, or unpredicted results from the final determination of each year’s liability by taxing authorities. These changes could have a significant impact on our financial position.

*Recent Accounting Pronouncements.* See Note 2—Summary of Significant Accounting Policies—Recent Accounting Pronouncements in Item 8, Part II.

## Item 7A. Quantitative and Qualitative Disclosures About Market Risk

In addition to the risks inherent in operations, we are exposed to financial, market, political and economic risks. The following discussion provides additional detail regarding our exposure to the risks related to changes in commodity prices, interest rates and foreign exchange rates.

*Commodity Price Risk.* Our primary product is metallurgical coal, which is in itself a commodity. The Company’s domestic sales contracts have terms of about one year and the pricing is typically fixed. Export sales have spot or term contracts, and pricing is often derived from an index. As such, we are exposed to changes in the international price of metallurgical coal.  

Our sales commitments as of February 25, 2026 are as follows:

| Line item | 2026 / Volume | 2026 / Average Price |
| --- | --- | --- |
| North America, fixed priced | 1.1 | $142 |
| Seaborne, fixed priced | - |  |
| Total, fixed priced | 1.1 | $142 |
| Index priced | 2.0 |  |
| Total committed tons | 3.1 |  |

​

Sales commitments of 0.8 million tons were obtained subsequent to December 31, 2025 and are included in the table above.

Sales commitments in the metallurgical coal market are typically not long-term in nature and, therefore, we are subject to fluctuations in market pricing. The Company’s shift to more export sales in its mix of revenues that has occurred during recent years exposes the Company’s revenues to greater volatility due to index-based pricing. The Company does not currently manage this risk through the use of derivative instruments. We also have exposure to price risk for supplies that are used directly or indirectly in the normal course of production such as diesel fuel, explosives, and other items. The Company manages its risk for these items through strategic sourcing contracts in normal quantities with our suppliers.

*Interest Rate Risk.* We are exposed to risk from changes in interest rates; however, based on the current levels of debt and leases, the Company does not attempt to manage our exposure to interest rate fluctuations. The Company has senior unsecured notes with a face value of $57.5 million that mature on November 30, 2029, unless redeemed prior to maturity, bearing interest at a fixed rate of 8.375% per annum and paid quarterly. The Company issued new senior unsecured notes during the fourth quarter of 2025 with a face value of $65.0 million that mature on July 31, 2030, unless redeemed prior to maturity, bearing interest at a fixed rate of 8.250% per annum and paid quarterly. The Company also issued new convertible senior notes during the fourth quarter of 2025 with a face value of $345 million that mature on November 1, 2031 unless exercised, redeemed or converted prior to that date, however, these notes do not bear interest.

Some of the Company’s debts may be affected by changes in benchmark interest rates, such as the Secured Overnight Financing Rate (“SOFR”). Borrowings under the Company’s Revolving Credit Facility, which has a maturity date of December 30, 2030 (subject to a springing maturity tied to convertible indebtedness), bear interest at either a base rate plus 2.0% or the applicable SOFR plus 2.5%. The base rate equals the highest of the administrative agent’s prime rate, the Federal Funds Effective Rate plus 0.5%, or 3.0%.

*Foreign Exchange Rate Risk.* International sales of coal are typically denominated in U.S. dollars. As a result, we do not have direct exposure to currency valuation exchange rate fluctuations. However, because our coal is sold internationally, to the extent that the U.S. dollar strengthens against the foreign currency of a customer or potential customer, we may find our coal at a price disadvantage as compared with other non-U.S. suppliers. This could lead to our receiving lower prices or being unable to compete for that specific customer’s business. Consequently, currency fluctuations could adversely affect the competitiveness of our coal in international markets.

**Definition and limitations of internal control over financial reporting**

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

### **Notes to Consolidated Financial Statements**

### NOTE 1—DESCRIPTION OF BUSINESS

Ramaco Resources, Inc. (the “Company,” “Ramaco,” “we,” “us” or “our,”) is a Delaware corporation formed in October 2016. Our principal corporate and executive offices are located in Lexington, Kentucky with operational offices in Charleston, West Virginia and Sheridan, Wyoming. We are an operator and developer of high-quality, low-cost metallurgical coal in southern West Virginia and southwestern Virginia. Our metallurgical coal development portfolio primarily includes the following properties: Elk Creek, Berwind, Knox Creek, and Maben. We believe each of these properties possesses geologic and logistical advantages that make our coal among the lowest delivered-cost U.S. metallurgical coal to our domestic customer base, North American blast furnace steel mills and coke plants, as well as to international metallurgical coal consumers. In mid-2025, we initiated development of our rare earth element and critical mineral operations near Sheridan, Wyoming (the “Brook Mine”). The Brook Mine initially produced representative ore material to serve as feedstock for testing, with the goal of demonstrating the viability of processing rare earth elements and critical minerals at a full-scale commercial facility and ultimately establishing mineral reserves and resources. Contiguous to the Brook Mine, the Company operates a carbon research facility related to the production of advanced carbon products and materials from coal. The Company’s operations are organized into two reportable segments: Metallurgical Coal and Rare Earths and Critical Minerals. See Note 14 for additional information.

### NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

*Basis of Presentation and Consolidation*—The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and U.S. Securities and Exchange Commission regulations. The financial statements are presented on a consolidated basis for all periods presented. All significant intercompany balances and transactions between consolidated entities have been eliminated in consolidation. Certain prior year amounts in the Notes to Consolidated Financial Statements have been adjusted to conform to current presentation.

*Use of estimates*—The preparation of these financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates are related to the quantity and value of coal inventories, stock-based compensation, asset retirement obligations, occupational disease obligations, evaluation of long-lived assets for impairment, quantities and values of coal reserves, depletion and amortization, useful lives, and income taxes.

*Revenue Recognition*—Our primary source of revenue is from the sale of coal through contracts with steel producers usually having durations of less than one year. Revenue is recognized when performance obligations under the terms of a contract with our customers are satisfied. This occurs when control of the coal is transferred to our customers. For coal shipments to domestic customers via rail, control is generally transferred when the railcar is loaded. Control is transferred for export coal shipments to customers via ocean vessel when the vessel is loaded at the port.

Our coal sales include up to 90-day payment terms following the transfer of control of the goods to our customer. In the case of some of our foreign customers, our contracts also require that letters of credit are posted to secure payment of any outstanding receivable. We do not include extended payment terms in our contracts. Our contracts with customers typically provide for minimum specifications or qualities of the coal we deliver. Variances from these specifications or qualities are settled by means of price adjustments. Generally, these price adjustments are settled within 30 days of delivery and are insignificant.

Certain of our contracts with customers include provisions in which the price is derived from an index. If control of the goods transfers to the customer in the period before the final price is determined, revenue is recorded based on the estimated consideration to be received. The Company estimates the amount to which it expects to receive by reference to forward curve data, if available, and generally does not constrain such estimates for accounting purposes

due to the short period of time over which the uncertainty is resolved. However, certain estimates of provisional pricing for which no forward curve data was available were constrained at December 31, 2023 due to index volatility. No estimates were constrained at December 31, 2024 or December 31, 2025.

*Freight Revenue and Expense*—Costs incurred to transport coal to the point of sale at the port facility are included in cost of sales and the gross amounts billed to customers to cover shipping to and handling of the coal at the port are included in revenue.

*Cash and Cash Equivalents*—We classify all highly-liquid instruments with an original maturity of three months or less as cash equivalents. Restricted cash balances at December 31, 2025 and December 31, 2024 were $0.8 million and consisted of funds held in escrow for potential future workers’ compensation claims. Restricted cash balances were included in other current assets on the balance sheet. The Company pools individual bank accounts with the same institution for the purpose of assessing if a bank overdraft exists based on the contractual terms of the arrangement.

Cash and cash equivalents consisted of the following:

​

| (In thousands) | December 31, 2025 | December 31, 2024 |
| --- | --- | --- |
| Cash | $35,635 | $33,009 |
| U.S. Treasury securities | 404,712 | — |
| Total cash & cash equivalents | $440,347 | $33,009 |

​

As of December 31, 2025, U.S. Treasury securities held by the Company represent Level 1 securities within the fair value hierarchy and are measured at fair value. See “Fair Value Measurements” below for further information.

​

*Inventories*— Coal is reported as inventory at the point in time it is extracted from the mine. Coal inventories are valued at the lower of average cost or net realizable value, with cost determined on a first-in, first-out inventory valuation method. Coal inventory costs include labor, supplies, equipment costs, freight, operating overhead, depreciation and amortization. Coal inventory quantities are adjusted periodically based on aerial surveys of coal stockpiles. Lower of cost or net realizable value adjustments are made as market conditions warrant. Supply inventories are valued at average cost. Inventories consisted of the following:

​

| (In thousands) | December 31, 2025 | December 31, 2024 |
| --- | --- | --- |
| Raw coal | $31,689 | $19,709 |
| Saleable coal | 48,522 | 17,969 |
| Supplies | 6,944 | 5,680 |
| Total inventories | $87,155 | $43,358 |

​

*Property, Plant and Equipment*—Property, plant and equipment is recorded at cost. Expenditures which extend the useful lives of existing plant and equipment are capitalized. Planned major maintenance costs which do not extend the useful lives of existing plant and equipment are expensed as incurred. When assets are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the respective accounts and any profit or loss on disposition is recognized in the Consolidated Statements of Operations.

Exploration costs are expensed as incurred. Exploration costs include those incurred to ascertain existence, location, extent or quality of ore or minerals before beginning the development stage of the mine.

Mining property and mineral rights costs represent the costs incurred to acquire the rights to access and mine certain coal property either through deeds, leases, or other conveyance agreements. These costs include the costs of acquiring and accessing mineral reserves, resources and surface areas for mining activities.

Mine development begins when the facts and circumstances clearly establish the presence of a commercial mineralized deposit. Capitalized mine development costs represent the costs incurred to prepare mine sites and/or seams

of coal for future mining. These costs include costs of acquiring, permitting, planning, research, and developing access to identified mineral reserves and other preparations for commercial production as necessary to develop and permit the properties for mining activities. When components of capitalized mine development costs are replaced with new components, the Company capitalizes the replacement as a separate component and charges off the net book value of the component that was replaced at the cease-use date.

If it is determined that an undeveloped mineral interest cannot be economically converted into proven and probable reserves, capitalized costs are assessed for impairment and future development costs are expensed as incurred. Operating expenditures, including certain professional fees and overhead costs, are not capitalized but are expensed as incurred.

Mineral rights and capitalized mine development costs are depleted and amortized on a units-of-production basis as mining of that mine’s assigned reserves takes place. Depreciation of plant and equipment is calculated on the straight-line method over their estimated useful lives ranging from three to thirty years.

*Advanced Coal Royalties*—In most cases, we acquire the right to mine coal reserves under leases which call for the payment of royalties on coal as it is mined and sold. These mineral leases typically require the payment of advance or minimum coal royalties to lessors that are recoupable against future production royalties. These advance payments are deferred and charged to operations as the coal reserves are mined.

*Impairment of Long-lived Assets*—We review and evaluate held-and-used long-lived assets, including property, plant and equipment and mine development costs, for impairment when events or changes in circumstances indicate that the asset or asset group’s carrying value may not be recoverable. Recoverability is measured by comparing the carrying amount of the asset or asset group to the estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying amount of the asset or asset group exceeds its estimated undiscounted future cash flows, an impairment loss is recorded for the excess of the carrying amount over the estimated fair value, if any. We may, under limited circumstances, idle mining operations in response to certain events or conditions. As idling mining operations does not represent a permanent closure of the mine, it is not considered an automatic indicator of impairment.

*Asset Retirement Obligations*—Legal obligations associated with the retirement of long-lived assets are initially recognized at their estimated fair value, with a corresponding charge to capitalized development costs, at the time they are incurred. Our asset retirement obligations primarily consist of spending estimates related to reclaiming metallurgical coal land and support facilities in accordance with federal and state reclamation laws as defined by each mining permit. Spending estimates are adjusted for inflation and then discounted at the credit-adjusted, risk-free rate. We record the fair value of a liability for an asset retirement obligation in the period in which it is incurred and a corresponding increase in the carrying amount of the related long-lived asset. The liability is accreted to its present value over time and the capitalized cost is amortized using the units-of-production method over estimated recoverable reserves upon commencement of mining. We review our asset retirement obligations on at least an annual basis for significant changes in the estimated timing and/or amount of cash flows.

*Occupational Disease (Pneumoconiosis) Obligations*. We recognize as a liability to provide for occupational disease (pneumoconiosis) benefits to eligible employees, former employees and dependents as required by the Federal Mine Safety and Health Act of 1969, as amended. The occupational disease benefit obligation represents the present value of the actuarially computed liabilities for such benefits over the employees’ applicable years of service.

Estimating our occupational disease (pneumoconiosis) benefits obligation requires management to make estimates and judgments regarding timing and existence of a liability utilizing third-party actuaries to assist in preparing what constitutes adequate liability amounts. Inherent in the calculation are numerous assumptions and judgments including the ultimate costs, mortality factors, credit-adjusted discount rates, and timing of settlement. Adjustments to estimated liabilities due to changes in actuarial assumptions are recorded immediately in earnings in the period in which the change in estimate occurs.

*Leases*—We determine if an arrangement is or contains a lease at contract inception, and lease classification is determined at the commencement date. Leases are recognized on the balance sheet as right-of-use (“ROU”) assets and lease liabilities except for leases with a term of 12 months or less.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at commencement date based on the present value of the fixed lease payments over the lease term. The Company does not separate lease and non-lease components for all leases as permitted under the accounting guidance for leases. As most of our leases do not contain a readily determinable implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating and finance lease ROU assets also include lease prepayments made by the Company and are reduced by any lease incentives received by the Company prior to commencement. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. For operating leases, lease expense is recorded in the income statement based on a straight-line recognition of the total fixed payments over the lease term. For finance leases, accretion of the liability is recognized as interest expense and the ROU asset is amortized separately on a straight-line basis similar to the depreciation of equipment owned by the Company.

Leases of mineral reserves and the related land leases are exempted under U.S. GAAP from recognition on the Consolidated Balance Sheets.

*Fair Value Measurements*— Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities that are recognized or disclosed at fair value are categorized in the fair value hierarchy based on the observability of the inputs utilized in the valuation. The levels of the hierarchy include: Level 1 - inputs are quoted prices in active markets for the identical assets or liabilities; Level 2 - inputs are other than quoted prices included in Level 1 that are directly or indirectly observable through market-corroborated inputs; and Level 3 - inputs are unobservable, or observable but cannot be market-corroborated, requiring us to make assumptions about pricing by market participants.

The fair values of cash and cash equivalents, accounts receivable, restricted cash, and accounts payable approximate their carrying amounts at each reporting date. Refer to Note 6 for additional information regarding the fair value of debt.

Nonrecurring fair value measurements of the Company include asset retirement obligations and estimated values used to allocate the acquisition cost of long-lived assets to individual assets, neither of which are subject to the fair value disclosure requirements.

The fair value of asset retirement obligations is determined as the present value of estimated cash flows related to reclamation obligations, which represent a Level 3 measurement due to the use of unobservable inputs such as estimates regarding the amount and timing of costs to be incurred, inflation rates, and the Company’s credit-adjusted discount rate.

The consideration for the Company’s previous acquisitions was allocated based on the relative fair values of the assets acquired, the primary asset of which was mineral rights. The fair values of mineral rights were determined based on Level 3 inputs, which are generally unobservable, requiring the Company to make assumptions about future coal prices, capital expenditures, future coal production, costs of production, and an appropriate rate at which to discount the future cash flows.

*Income Taxes*—Income tax expense (benefit) includes Federal and state income taxes. Certain income and expenses are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported as deferred income taxes. We account for deferred income taxes by applying statutory tax rates in effect at the reporting date of the balance sheet. A valuation allowance is established if it is more likely than not that the related tax benefits will not be realized. In determining the appropriate valuation allowance, we consider the projected realization of tax benefits based on expected levels of future taxable income, available tax planning strategies and

reversals of existing taxable temporary differences. The Company had no valuation allowances on the balance sheet as of December 31, 2025 and 2024.

Uncertain tax positions are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. We had no significant uncertain tax positions requiring liability recognition as of December 31, 2025 and 2024. We file income tax returns in the U.S. and in various state and local jurisdictions which may be routinely examined by tax authorities. The statute of limitations for examination of the Company’s tax filings by taxing authorities is currently open for tax returns filed for the year 2022 and thereafter.

The Company recognizes penalties and accrued interest related to income tax matters in *Other income (expense), net* and *Interest expense net*, respectively, separately from the tax provision recorded in *Income tax expense* on the income statement.

*Stock-Based Compensation*—Compensation cost for equity awards is based on the grant-date fair value of the award and is recognized over the requisite service period. For awards with graded vesting, the Company recognizes compensation cost on a straight-line basis over the requisite service period of the entire award. Forfeitures are recognized as they occur.

The fair values of restricted stock and restricted stock unit awards having only a service condition were determined using the publicly-traded price of our common stock on the grant date. The fair value of performance stock units, which vest based on the achievement of relative total shareholder return goals, was determined on the date of grant based on a Monte Carlo simulation. The fair value of stock option awards was calculated using the Black-Scholes option-pricing model. The Black-Scholes model requires us to make assumptions and judgments about the variables used in the calculation, including the expected term, expected volatility, risk-free interest rate, dividend rate and service period.

*Concentrations*—Our current revenue generating operations are all related to metallurgical coal within the mining industry. A reduction in metallurgical coal prices or other disturbances in the metallurgical coal markets could have an adverse effect on our financial results.

During 2025, sales to three customers accounted for 13%, 11 %, and 10% of our revenues, or collectively 34% of total revenue. During 2024, sales to two customers accounted for 11% and 10% of our revenues, or collectively 21% of total revenue. During 2023, sales to three customers accounted for 15%, 13%, and 13% of our revenues, or collectively 41% of total revenue. The number of customers comprising the concentrations above is based on a threshold of 10% or more of total revenues.

Financial instruments that potentially subject us to a significant concentration of credit risk consist primarily of cash and cash equivalents, restricted cash, and accounts receivable. We monitor the credit ratings and concentration of risk with financial institutions on a continuing basis to safeguard our cash deposits. In addition, the Company is party to an arrangement that began in 2023 whereby our cash and cash equivalents are placed at various banks in amounts no greater than the $250,000 FDIC-insured limit to help safeguard against potential losses in the financial sector.

We have a limited number of customers. Contracts with these customers provide for billings principally upon shipment and compliance with payment terms is monitored on an ongoing basis. Outstanding receivables beyond payment terms are promptly investigated and discussed with the specific customer. We estimate an allowance for credit losses by taking into consideration the age of past due accounts and an assessment of our customers’ ability to pay. An allowance for credit losses was not necessary as of December 31, 2025 and 2024.

Three customers accounted for 23%, 18%, and 10%, of our trade receivables, or collectively 51% of the Company’s accounts receivable balance at December 31, 2025. At December 31, 2024, five customers accounted for 18%, 16%, 12%, 11% and 10% of our trade receivables, or collectively 67%. The number of customers comprising the concentrations above is based on a threshold of 10% or more of total accounts receivable.

*Recent Accounting Standards Updates*

In December 2023, the FASB issued ASU 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures* (“ASU 2023-09”). ASU 2023-09 standardizes categories for the effective tax rate reconciliation, requires disaggregation of income taxes paid and additional income tax-related disclosures, and is effective for the Company for annual fiscal periods beginning after December 15, 2024. The Company has retrospectively adopted ASU 2023-09 in the current year which impacts the Company’s disclosures within Note 12. Because the ASU affects disclosures only, the adoption did not affect the Company’s Consolidated Statements of Operations or Consolidated Balance Sheets.

In November 2024, the FASB issued ASU 2024-03, *Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses* (“ASU 2024-03”). The amendments in ASU 2024-03 require public business entities to disclose in the notes to the financial statements, among other things, specific information about certain costs and expenses including purchases of inventory, employee compensation, and depreciation, amortization, and depletion expenses for each caption on the income statement where such expenses are included. ASU 2024-03 is effective starting with the Company’s 2027 annual financial statements and on a quarterly basis thereafter. Early adoption is permitted, and the amendments may be applied prospectively to reporting periods after the effective date or retrospectively to all periods presented in the financial statements. The Company is currently evaluating the extent to which its disclosures will be affected by the ASU.

In December 2025, the FASB issued ASU 2025-10, *Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities* (“ASU 2025-10”), which provides updated guidance on how to recognize, measure, and present government grants. ASU 2025-10 is effective starting with the Company’s 2029 annual financial statements and on a quarterly basis thereafter, with early adoption permitted. The Company is currently evaluating the effect of this update on our consolidated financial statements.

At December 31, 2025 and 2024, mining property and mineral rights above include $18.5 million and $16.2 million, respectively, of carrying value associated with coal mineral reserves and resources attributable to complexes where we are not currently engaged in mining operations, and therefore, the coal mineral reserves are not currently being depleted. We believe that the carrying value of these coal mineral reserves will be recovered.

On March 17, 2025, the Company announced that it received a $6.1 million matching grant authorized by Wyoming Governor Mark Gordon and issued by the Wyoming Energy Authority for Ramaco’s CORE Brook Mine project. The funding is intended to support Ramaco’s significant future investment in constructing and equipping a rare earth and critical minerals processing facility near Sheridan, Wyoming.

​

The Company sponsors a defined contribution plan to assist eligible employees in providing for their future retirement needs. Contribution expenses related to the plan totaled $3.9 million, $4.0 million, and $3.1 million for the years ended December 31, 2025, 2024, and 2023, respectively.

​

*Other long-term liabilities* were comprised primarily of worker’s compensation and occupational disease obligations discussed below.

​

*Workers’ Compensation and Occupational Disease Obligations*

​

We are self-insured for certain losses relating to workers’ compensation claims and occupational disease obligations under the Federal Mine Safety and Health Act of 1969, as amended. Starting in 2023, the Company also elected to self-insure employee medical expenses. We purchase insurance coverage to reduce our exposure to significant levels of these claims. Self-insured losses are accrued based upon estimates of the aggregate liability for uninsured claims incurred as of the balance sheet date using claims data and actuarial assumptions. The occupational disease

benefit obligation represents the present value of the actuarially computed liabilities for such benefits over the employees’ applicable years of service.

​

As of December 31, 2025, the estimated aggregate liability for claims totaled $10.2 million, including $3.4 million of occupational disease obligations. Of the aggregate liability, $7.4 million was included in *Other long-term liabilities* on the Consolidated Balance Sheets. In addition, the Company recognized an expected recovery asset of $2.0 million in *Other* noncurrent assets related to the reimbursement of workers’ compensation amounts that are reimbursable under insurance purchased by the Company. As of December 31, 2024, the estimated aggregate liability totaled $8.3 million, including $2.4 million of occupational disease obligations. Of the aggregate liability, $5.2 million was included in *Other long-term liabilities* within the Consolidated Balance Sheets.

​

The Company recognized an actuarial loss of $0.2 million in the fourth quarter of 2025 related to the annual measurement of our occupational disease benefit obligation, which was due, in part, to the decrease in the discount rate assumption. The occupational disease benefit liability was calculated using a discount rate of 5.6% and 5.9% at December 31, 2025 and 2024, respectively. Disclosures of net periodic benefit cost and estimated future cash payments related to occupational disease benefits have been omitted due to immateriality.

​

​

*9.00% Senior Unsecured Notes due 2026*—On July 13, 2021, we completed an offering of $34.5 million, in the aggregate, of the Company’s 9.00% Senior Unsecured Notes due 2026 (the “2026 Senior Notes”). These notes mature on July 30, 2026, unless redeemed prior to maturity. The 2026 Senior Notes bear interest at a rate of 9.00% per annum, payable quarterly in arrears on the 30th day of January, April, July and October of each year, commencing on July 30, 2021. We may redeem the 2026 Senior Notes in whole or in part, at our option, at any time on or after July 30, 2023, or upon certain change of control events, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to, but not including, the date of redemption. Issuance-related costs for the 2026 Senior Notes included underwriters’ fees, attorney, accounting and filing costs totaling $2.4 million. The outstanding principal remained at $34.5 million as of December 31, 2024 and was repaid in full on July 31, 2025 with the proceeds from the issuance of 8.250% Senior Unsecured Notes due 2030 described below.

*8.375% Senior Unsecured Notes due 2029—*On November 27, 2024, the Company completed an offering of $50.0 million, in the aggregate, of 8.375% Senior Unsecured Notes due 2029 (the “2029 Senior Notes”) and on December 11, 2024, the Company closed on an additional $7.5 million of aggregate principal amount of 2029 Senior Notes (the “2029 Senior Note Offering”). The 2029 Senior Notes mature on November 30, 2029, unless redeemed prior to maturity. The 2029 Senior Notes bear interest at a rate of 8.375% per annum, payable quarterly in arrears on the 30th day of January, April, July and October of each year, commencing on January 30, 2025. The Company may redeem the 2029 Senior Notes in whole or in part, at the Company’s option, at any time on or after November 30, 2026, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to, but not including, the date of redemption.

Issuance-related costs for the 2029 Senior Notes included underwriters’ fees, attorney, accounting and filing costs totaling $3.1 million. These costs are reported as a debt discount which is being amortized over the term of the 2029 Senior Notes using the effective interest method. The outstanding principal remains at $57.5 million; however, the balance of the Senior Notes due 2029 reported at December 31, 2025 was $54.9 million, which is net of unamortized issuance-related costs of $2.6 million. The effective interest rate is approximately 9.78%.

*8.250% Senior Unsecured Notes due 2030—*On July 31, 2025, the Company completed a public offering of 8.250% Senior Unsecured Notes due 2030 (the “2030 Senior Notes”) having an aggregate principal amount of $57.0 million with an option for the underwriters to purchase an additional $8.0 million of aggregate principal which was exercised by the underwriters on August 1, 2025 (the “2030 Senior Note Offering”). The 2030 Senior Notes mature on July 31, 2030, unless redeemed prior to maturity and bear interest at a rate of 8.25% per annum, payable quarterly in arrears on the 30th day of January, April, July and October of each year, commencing on October 30, 2025. The Company may redeem the 2030 Senior Notes in whole or in part, at the Company’s option, at any time on or after July 31, 2027, or upon certain change of control events, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to, but not including, the date of redemption.

Issuance-related costs for the 2030 Senior Notes included underwriters’ fees, attorney, accounting and filing costs totaling $3.5 million. These costs are reported as a debt discount which is being amortized over the term of the 2030 Senior Notes using the effective interest method. The outstanding principal remains at $65.0 million; however, the balance of the Senior Notes due 2030 reported at December 31, 2025 was $61.7 million, which is net of unamortized issuance-related costs of $3.3 million. The effective interest rate is approximately 9.62%.

*0.0% Convertible Senior Notes due 2031—*On November 4, 2025 the Company completed a public offering of 0.0% Convertible Senior Notes due 2031 (the “2031 Convertible Senior Notes”), having an aggregate principal amount of $300.0 million with an option for the underwriters to purchase an additional $45.0 million of aggregate principal which was exercised by the underwriters on November 5, 2025. The 2031 Convertible Senior Notes do not bear regular interest and the principal amount does not accrete. The 2031 Convertible Senior Notes mature on November 1, 2031, unless earlier repurchased, redeemed or converted. The Company used a portion of the net proceeds to fund the cost of entering into capped call transactions described within Note 8.

Before August 1, 2031, noteholders will have the right to convert their 2031 Convertible Senior Notes only upon the occurrence of certain events. From and after August 1, 2031, noteholders may convert their 2031 Convertible Senior Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, shares of its Class A common stock or a combination of cash and shares of its Class A common stock, at the Company’s election. The initial conversion rate will be 30.5460 shares of the Class A Common Stock per $1,000 principal amount of 2031 Convertible Senior Notes, which represents an initial conversion price of approximately $32.74 per share of the Class A common stock.

The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. In addition, upon a Make-Whole Fundamental Change (as defined in the indenture governing the 2031 Convertible Senior Notes), the conversion rate may be increased for a specified period of time based on the trading price of the Company’s Class A common stock. The maximum increase to the conversion rate in such an event is 41.2371 shares per $1,000 principal amount, which results in up to approximately 14,226,800 additional shares if all 2031 Convertible Senior Notes are converted during such period and fully settled in shares.

The 2031 Convertible Senior Notes are redeemable, in whole or in part, at the Company’s option at any time on or after November 6, 2028, and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of the Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days during the 30 consecutive trading days ending on the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such redemption notice. In addition, calling (or the deemed calling of) any convertible note for redemption will constitute a Make-Whole Fundamental Change with respect to that convertible note, in which case the conversion rate will be increased in certain circumstances if it is converted after it is called for redemption.

The Company accounted for the 2031 Convertible Senior Notes as a single liability instrument, presented within *Long-term debt, net* on the Consolidated Balance Sheets.

Issuance-related costs for the 2031 Convertible Senior Notes included underwriters’ fees, attorney, accounting and filing costs totaling $10.5 million. These costs are reported as a debt discount which is being amortized over the term of the 2031 Convertible Senior Notes using the effective interest method. The outstanding principal remains at $345.0 million; however, the balance of the 2031 Convertible Senior Notes reported at December 31, 2025 was $334.8 million, which is net of unamortized issuance-related costs of $10.2 million. The effective interest rate is approximately 0.52%.

Concurrently with the Convertible Notes Offering, a delta placement of borrowed shares was conducted to facilitate hedging by certain investors. The Company did not issue any shares in connection with this arrangement.

*Revolving Credit Facility—* On December 30, 2025, the Company entered into a Third Amended and Restated Credit and Security Agreement (the “Credit Agreement”), which includes KeyBank National Association (“KeyBank”) and multiple lending parties, in order to, among other things, extend the maturity date and increase the size of the facility. The amended facility (the “Revolving Credit Facility”) has a maturity date of December 30, 2030 (subject to a springing maturity tied to convertible indebtedness), and provides an initial aggregate revolving commitment of $350.0 million as well as an accordion feature to increase the size by an additional $150.0 million subject to certain terms and conditions, including lenders’ consent.

Previously, the Second Amendment Agreement to the Second Amended and Restated Credit and Security Agreement dated November 21, 2024 had a maturity date of May 3, 2029 and an initial aggregate revolving commitment of $200.0 million as well as an accordion feature of $75.0 million. On July 23, 2025, in order to facilitate the 2030 Senior Note Offering described above, the Company entered into a Third Amendment Agreement, which, among other things, permitted the Company to incur additional indebtedness in the form of unsecured notes to be issued in the 2030 Senior Note Offering in an aggregate principal amount not to exceed $100.0 million (the “2030 Unsecured Note Basket”), conditioned upon the full redemption of the Company’s 2026 Senior Notes, and reduced the amount of “Permitted Additional Unsecured Debt” from $75.0 million to $15.0 million plus the unused portion of the 2030 Unsecured Note Basket. On August 5, 2025, the Company entered into a Fourth Amendment Agreement, which, among other things, amended the Credit Agreement by removing all negative covenants relating to the issuance of equity securities by the Company.

The borrowing base of the amended facility as of December 31, 2025 was $80.7 million based on eligible accounts receivable and inventory collateral and reserve requirements. There were no outstanding borrowings on the Revolving Credit Facility at December 31, 2025.

Revolving loans under the amended facility bear interest at either the base rate plus 2.0% or the Secured Overnight Financing Rate plus 2.5%. The base rate equals the highest of the administrative agent’s prime rate, the Federal Funds Effective Rate plus 0.5%, or 3.0%. The effective interest rate for borrowings during 2025 was 6.83%.

The terms of the Revolving Credit Facility include covenants limiting the ability of the Company to incur additional indebtedness, make investments or loans, incur liens, consummate mergers and similar fundamental changes, make restricted payments, and enter into transactions with affiliates. The terms of the facility also require the Company to maintain certain covenants, including a fixed charge coverage ratio and compensating balance requirements. A fixed charge coverage ratio of not less than 1.10:1.00 must be maintained by the Company during any period when excess availability is less than 12.5% of the maximum borrowing amount, tested as of quarter-end for the trailing four fiscal quarters. In addition, the Company must maintain an average daily cash balance of $5.0 million, as determined on a monthly basis, in a dedicated account as well as an additional $1.5 million and $1.0 million in separate dedicated accounts to assure future credit availability. At December 31, 2025, the Company was in compliance with all debt covenants under the Revolving Credit Facility.

*Komatsu Financial Limited Partnership Loan—*On August 16, 2021, we entered into an equipment loan with Komatsu Financial Limited Partnership, as lender, in the principal amount of approximately $1.0 million for the

financing of surface equipment (the “Komatsu Equipment Loan”). Additional equipment loans of $0.7 million were entered into during October 2022. The Komatsu Equipment Loan bears interest at 4.66% per annum and is payable in 36 monthly installments of $36 thousand for the first six months and then at $28 thousand until maturity. The outstanding principal balance of the Komatsu Equipment Loan was less than $0.1 million and $0.2 million at December 31, 2025 and December 31, 2024, respectively.  

*Brandeis Machinery & Supply Company—*On January 11, 2022, we entered into equipment loans with Brandeis Machinery & Supply Company, as lender, in the principal amount of $1.4 million for the financing of surface equipment (the “Brandeis Equipment Loans”). The Brandeis Equipment Loans bear interest at 4.8% per annum and are payable in 48 monthly installments. The outstanding principal balance of the Brandeis Equipment Loans was less than $0.1 million and $0.2 million at December 31, 2025 and December 31, 2024, respectively.

*Fair Value*—The Company’s 2029 Senior Notes had an estimated fair value of $58.3 million and $58.1 million at December 31, 2025 and December 31, 2024, respectively. The Company’s 2030 Senior Notes, which were issued on July 31, 2025, had an estimated fair value of $65.7 million at December 31, 2025. The Company’s 2026 Senior Notes, which were repaid on July 31, 2025, had an estimated fair value of $35.6 million at December 31, 2024. The Company’s 2031 Convertible Senior Notes, which were issued on November 4, 2025, had an estimated fair value of $292.9 million at December 31, 2025. The fair values of the Company’s debt instruments were based publicly traded market prices and were considered a Level 2 measurement based on trading volumes. The difference between the fair value and carrying amount of the Company’s remaining debts is not material due to the similarity between the terms of the debt agreements and prevailing market terms available to the Company.

*Current Portion of Long-term Debt—*The Company’s short-term debt at December 31, 2025 and December 31, 2024 comprised of $0.1 million and $0.4 million due under equipment loans with a weighted average interest rate of approximately 4.7% for each period.

*Insurance financing—*The Company financed premium payments of $7.0 million associated with various insurance policies during 2025, which must be repaid to a third-party finance company in monthly installments over a one-year term. The outstanding debt balance was $4.0 million at December 31, 2025, which is not reflected in the tables above or below.

Maturities of our debt are presented below, which are $16.1 million higher than total debt on the balance sheet due to debt-related issuance costs to be accreted over future periods.

### **NOTE 7—LEASES**

​

The Company has various finance leases for mining equipment, which generally include 3-5 year terms and expire through 2030. In addition, we have two operating leases for office space with initial terms of approximately five and six years that run through 2027 and 2030, respectively, including the office space in Charleston, WV that commenced in the first quarter of 2024 resulting in the recognition of an additional right-of-use asset and lease liability of approximately $1.0 million.

​

Amortization of right-of-use assets associated with finance leases was $7.8 million, $10.4 million, and $8.5 million in 2025, 2024, and 2023, respectively, as discussed in Note 3. Interest expense recognized for financing lease liabilities was $1.5 million, $0.9 million, and $0.6 million in 2025, 2024, and 2023, respectively. Operating lease expense was $0.4 million, $0.4 million, and $0.2 million in 2025, 2024, and 2023, respectively.

​

Right-of-use assets and lease liabilities are determined as the present value of the lease payments, discounted using either the implicit interest rate in the lease or, more commonly, our estimated incremental borrowing rate based on similar terms, payments and the economic environment where the leased asset is located. Below is a summary of our leases:

### NOTE 8—EQUITY

On June 12, 2023, an amendment to the Company’s amended and restated certificate of incorporation was approved by shareholder vote to reclassify the Company’s existing common stock as shares of Class A common stock and create a separate Class B common stock. We are authorized to issue up to a total of 225,000,000 shares of Class A common stock and 35,000,000 shares of Class B common stock as well as 50,000,000 shares of preferred stock, each having a par value of $0.01 per share.

The initial distribution of Class B common stock occurred on June 21, 2023 via a stock dividend to existing holders of common stock as of May 12, 2023. On the date of initial distribution, each holder of common stock received 0.2 shares of Class B common stock for every one share of existing common stock held on the record date. Similar actions or modifications occurred for holders of outstanding stock-based awards.

The distribution of the Class B common stock provides existing holders of the Company’s common stock with an opportunity to participate directly in the financial performance of the Company’s CORE assets on a stand-alone basis, separate from the Company’s metallurgical coal operations. CORE assets were acquired initially as part of the Company’s acquisition of Ramaco Coal in the second quarter of 2022. The financial performance of CORE assets consists of the following non-cost-bearing revenue streams based on the Company’s current expectations:

- Royalty fees derived from the royalties associated with the Ramaco Coal and Amonate reserves, which we believe approximates 3% of Company-produced coal sales revenue excluding coal sales revenue from Knox Creek,
- Infrastructure fees based on $5.00 per ton of coal processed at our preparation plants and $2.50 per ton of loaded coal at the Company’s rail load-out facilities, and
- Future income derived, if and when realized, from advanced carbon products and rare earth elements initiatives.

​

The Company has paid dividends equal to 20% of the total fees above; however, any dividend amounts declared and paid are subject to the sole discretion of the Company’s Board of Directors.

​

In addition, the Board of Directors retains the power to change or add expense allocation policies related to CORE, redefine CORE assets, and redetermine CORE’s per-ton usage fees at any time, in its sole discretion, without shareholder approval. Holders of shares of Class A common stock continue to be entitled to receive dividends when and if declared by the Board of Directors subject to any statutory or contractual restrictions on the payment of dividends and to any prior rights and preferences that may be applicable to outstanding preferred stock, if any.

​

CORE is not a separate legal entity, and holders of Class B common stock do not own a direct interest in the assets of CORE. Holders of Class B common stock are stockholders of Ramaco Resources, Inc. and are subject to all risks and liabilities of the Company as a whole.

​

With respect to voting rights, holders of Class A common stock and Class B common stock vote together as a single class on all matters submitted to a vote of the stockholders and are entitled to one vote per share. The holders of Class A common stock and Class B common stock do not have cumulative voting rights in the election of directors. Class B common stock does not have any specific voting rights or governance rights with respect to CORE.

​

With respect to liquidation rights, holders of common stock are entitled to receive ratably the assets available for distribution to the stockholders after payment of liabilities and the liquidation preference of outstanding preferred stock, if any. That is, the rights to residual net assets upon liquidation are equal between holders of Class A and Class B common stock. Holders of Class B common stock do not have specific rights to CORE assets in the event of liquidation.

​

Shares of Class A common stock have no preemptive or conversion rights and are not subject to further calls or assessment by us. There are no redemption or sinking fund provisions applicable to Class A common stock. The Board of Directors retains the ability, in its sole discretion, to exchange all outstanding shares of Class B common stock into Class A common stock based on an exchange ratio determined by a 20-day trailing volume-weighted average price for each class of stock. If conversion were to have occurred on December 31, 2025, the Company would have issued approximately 7.2 million shares of Class A common stock and potential common shares of Class A in exchange for Class B common shares and unvested awards.

​

The initial distribution of the tracking stock was recorded as a stock dividend at fair value, which was estimated to be $11.00 per share based on the closing price of Class B shares on the first day of regular-way trading. The effect of the equity restructuring was a $102.9 million reduction in retained earnings and an increase of $102.9 million to Class B common stock and additional paid-in capital during the second quarter of 2023. The Company initially distributed 8,201,956 shares of Class B common shares as well as additional restricted stock, restricted stock units, and performance stock units discussed below*.*

​

*Class A Common Stock Issuance*

On August 7, 2025, the Company completed an underwritten public offering, with Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC as underwriters, relating to the issuance of 10,666,667 shares of the Company’s Class A common stock at a price to the public of $18.75 per share. The Underwriters purchased the shares of common stock at a price of $17.71875 per share. The net proceeds were approximately $188.1 million, after deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company. The Company intends to use the net proceeds for the development of our rare earth elements and critical minerals project, for strategic growth opportunities, and for general corporate purposes.

​

*Stock Repurchase Program*

In December 2025, the Board of Directors authorized the repurchase of up to $100 million of Company's Class A common stock over a period of 24 months (the “2025 Stock Repurchase Program”). Under the 2025 Stock Repurchase Program, the Company may repurchase shares through open market purchases, privately-negotiated transactions, block purchases or otherwise. The Board of Directors also authorized the Company to enter into written trading plans under Rule 10b-18 of the Exchange Act with a third-party broker to facilitate the repurchase of its Class A common stock pursuant to the 2025 Stock Repurchase Program. As of December 31, 2025, the Company had not repurchased any shares under the 2025 Stock Repurchase Program.

​

*Stock-Based Compensation Awards*

Outstanding stock-based awards were reclassified to Class A common stock as part of the equity restructuring discussed above. In addition, pursuant to the terms of the Company’s outstanding stock-based awards, equitable adjustments were made in accordance with such terms, as discussed below, based on the same factor of 0.2 for every outstanding award. Since there were no changes in fair value, vesting conditions, or award classification, no incremental compensation expense resulted.

Our Long-Term Incentive Plan (“LTIP”) is currently authorized by shareholders for the issuance of awards of up to approximately 10.9 million shares of common stock. As of December 31, 2025, there were approximately 3.3 million shares of common stock available for grant under the LTIP.

In general, granted but unvested shares are forfeited upon termination of employment, unless an employee enters into another written arrangement. However, exceptions exist under certain circumstances upon a change in control event. Granted but unvested shares may not be sold, assigned, transferred, pledged or otherwise encumbered.

As of December 31, 2025, we had four types of stock-based awards outstanding: stock options, restricted stock, restricted stock units, and performance stock units. Stock-based compensation expense for all stock-based awards totaled $17.6 million in 2025, $17.5 million in 2024, and $12.9 million in 2023.

The following table summarizes the remaining stock-based awards outstanding, as well as activity for the periods:

​

​

The total fair value of awards vested was $6.8 million during 2025, $28.9 million during 2024, and $19.7 million during 2023, excluding the fair value of shares to be issued in 2025 for PSUs with an evaluation period ending on December 31, 2025, which was $10.3 million.

*Stock Options—*We granted options  for the purchase of a total of 937,424 shares of our common stock for $5.34 per share to two executives on August 31, 2016. The options have a ten-year term from the grant date and are fully vested. During the third quarter of 2022, options to purchase 20,000 shares of common stock options with an intrinsic value of $0.1 million were exercised, leaving a balance of options to purchase 917,424 shares of common stock at December 31, 2022. During 2023, stock options of 183,484 shares of Class B awards were distributed to these individuals under the equitable adjustments discussed above. During the fourth quarter of 2023, options to purchase 168,712 shares of Class A common stock were exercised and stock options for 33,742 shares of Class B common stock were exercised having a combined intrinsic value of $2.6 million. The remaining options outstanding and unexercised at December 31, 2023 were 748,712 for Class A common stock and 149,742 for Class B common stock. During the third quarter of 2024, options to purchase 100,000 shares of Class A common stock were exercised and stock options for 20,000 shares of Class B common stock were exercised having a combined intrinsic value of $0.6 million. During the fourth quarter of 2024, stock options of 12,034 were distributed to these individuals for the non-cash dividend and stock dividend discussed later in this note. During the third quarter of 2025, options to purchase 150,000 shares of Class A common stock were exercised and stock options for 30,000 shares of Class B common stock were exercised having a combined intrinsic value of $0.8 million. The remaining options outstanding and unexercised at December 31, 2025 were 498,712 for Class A common stock and 108,697 for Class B common stock, which were in-the-money at December 31, 2025, having a total intrinsic value of $2.7 million. No compensation expense was recognized for these awards in 2025, 2024, or 2023 as the awards became fully vested in previous years.

*Restricted Stock**—*We grant shares of restricted stock to certain senior executives, key employees and directors. These shares vest over approximately one to three and a half years from the date of grant. During the vesting period, the participants have voting rights and may receive dividends. Upon vesting, the restricted stock becomes unrestricted common shares. The fair value of the restricted stock on the date of the grant is amortized ratably over the service period. At December 31, 2025, there was $2.7 million of total unrecognized compensation cost related to unvested restricted stock to be recognized over a weighted-average period of 1.9 years. The fair value of restricted stock awards that vested during 2025 was $1.3 million for Class A awards and $0.1 million for Class B awards. The fair value of the outstanding restricted stock awards was $8.4 million for Class A awards and $0.3 million for Class B awards based on the year-end 2025 closing stock prices.

*Restricted Stock Units—*We grant shares of restricted stock units to certain senior executives and key employees. These share units vest ratably over approximately three years from the date of grant. During the vesting period, the participants have no voting rights and no dividend rights; however, participants are entitled to receive dividend equivalents, which shall be subject to the same conditions applicable to the units and payable at the time the units vest. Upon vesting and within 30 days thereafter, the recipient will receive one share of common stock for each stock unit.

The grant date fair values of restricted stock units are recognized ratably over the service period. At December 31, 2025, there was $5.9 million of total unrecognized compensation cost related to unvested restricted stock units to be recognized over the weighted average period of 2.1 years. The fair value of restricted stock unit awards that vested during 2025 was $2.6 million for Class A awards and $0.3 million for Class B awards. The fair value of the outstanding restricted stock unit awards was $18.9 million for Class A awards and $0.6 million for Class B awards based on the year-end 2025 closing stock prices.

*Performance Stock Units—*We grant shares of performance stock units to certain senior executives and key employees. These share units cliff-vest approximately three years from the date of grant based on the achievement of targeted performance levels related to pre-established relative total shareholder return goals. These performance stock units have the potential to be earned from 0% to 200% of target depending on actual results. During the vesting period, the participants have no voting rights and no dividend rights; however, participants are entitled to receive dividend equivalents, which shall be subject to the same conditions applicable to the units and payable at the time the units vest. Upon vesting and within 30 days thereafter, the recipient will receive one share of common stock for each stock unit.

The Company’s performance stock units were valued relative to the stock price performance of a peer group of companies, which was based on a Monte Carlo simulation. The fair value of the performance stock units on the date of the grant is recognized ratably over the service period. At December 31, 2025, there was $10.5 million of total unrecognized compensation cost related to unvested performance stock units to be recognized over the weighted average period of 1.7 years. The fair value of performance stock unit awards that vested during 2025 was $2.2 million for Class A awards and $0.3 million for Class B awards. The combined fair value of the outstanding performance stock units for both classes, at target, was $18.7 million at December 31, 2025, excluding the fair value of the awards with an evaluation period that concluded on December 31, 2025 of $10.3 million.

Performance stock units originally granted in 2022 were modified during the first quarter of 2023. Modifications to these awards were made up primarily of changes in the composition of the peer group as well as changes in the way relative total shareholder return is evaluated against the updated peer group. The modification resulted in incremental fair value of $1.2 million, which was recognized as expense over 2023 and 2024.

Performance stock units are accounted for as awards with a market condition since vesting depends on total shareholder return relative to a group of peer companies.

*Modification—* The resignation of one of the Company’s executive officers and the separation agreement between the employee and the Company that occurred during the first quarter of 2024 resulted in a net charge to stock compensation expense of $1.2 million during the period. Incremental value of $1.8 million resulted from the continued equity vesting provision included in the separation agreement applicable to the employee’s restricted stock awards, which was recognized as expense. This amount was offset partially by the $0.6 million reversal of previously recognized

compensation expense related to the pre-modified restricted stock award ($0.3 million) as well as the forfeiture of restricted stock units and performance stock units (collectively $0.3 million).

*Taxes Related to Stock Awards—*The Company routinely allows employees to surrender common stock to pay estimated taxes upon the vesting or exercise of stock-based compensation awards. The value of common stock tendered by employees is determined based on the price of the Company’s common stock at the time of relinquishment. Employees surrendered approximately 0.1 million total shares for $3.5 million, 0.9 million total shares for $10.6 million, and 0.2 million total shares for $3.2 million during 2025, 2024, and 2023, respectively. There were no other repurchases of common shares.

*Capped Call Transactions*

In connection with the 2031 Convertible Senior Notes Offering described in Note 6, the Company purchased privately negotiated capped calls with certain financial institutions pursuant to capped call confirmations (collectively the “capped calls”). The capped calls each have an initial strike price of $32.7375 per share, subject to certain adjustments, which corresponds to the initial conversion price of each of the 2031 Convertible Senior Notes. The number of shares underlying the capped calls is approximately 10.5 million shares of Class A common stock. The capped calls have an initial cap price of $54.5625 per share, subject certain adjustments. By entering into the capped calls, the Company expects to reduce the potential dilution to its common stock (or, in the event the conversion is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion its stock price exceeds the conversion price under the Convertible Notes. The capped calls are subject to either adjustment or termination upon the occurrence of specified extraordinary events affecting the Company, including a merger event, a tender offer, and a nationalization, insolvency or delisting involving the Company. Additionally, the capped calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including changes in law, insolvency filings, and hedging disruptions. As the capped calls represent separate transactions from the 2031 Convertible Senior Notes and qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer’s own stock and classified in stockholder’s equity in the Consolidated Balance Sheets, the aggregate amount paid for the capped calls of $32.8 million, inclusive of the premium, was recorded as a reduction to *Additional paid-in capital* in the Consolidated Balance Sheets and will not be remeasured. As of December 31, 2025, we have not exercised any capped calls.

​

### NOTE 9—COMMITMENTS AND CONTINGENCIES

*Environmental Liabilities***—**Environmental liabilities are recognized when the expenditures are considered probable and can be reasonably estimated. Measurement of liabilities is based on currently enacted laws and regulations, existing technology and undiscounted site-specific costs. Generally, such recognition would coincide with a commitment to a formal plan of action. No amounts have been recognized for environmental liabilities.

*Surety Bond*—In accordance with state laws, we are required to post reclamation bonds to assure that reclamation work is completed. We also have a small amount of surety bonds that secure performance obligations. Bonds outstanding at December 31, 2025 totaled approximately $36.0 million.

*Coal Leases and Associated Royalty Commitments*—We lease coal reserves under agreements that require royalties to be paid as the coal is mined and sold. Many of these agreements require minimum annual royalties to be paid regardless of the amount of coal mined and sold. Total royalty expenses were $21.9 million, $27.9 million, and $35.0 million for the years ended December 31, 2025, 2024 and 2023, respectively. These agreements generally have terms running through exhaustion of all the mineable and merchantable coal covered by the respective lease. Royalties or throughput payments are based on a percentage of the gross selling price received for the coal we mine. Minimum royalty obligations under coal leases total $31.8 million consisting of, $3.7 million per year from 2026 through 2030 and $13.3 million thereafter.

*Contingent Transportation Purchase Commitments*—We secure the ability to transport coal through rail contracts and export terminals that are sometimes funded through take-or-pay arrangements. As of December 31, 2025, the Company’s remaining commitments under take-or-pay arrangements totaled $12.3 million, the majority of which relates to a multi-year contract with total remaining commitments of $11.4 million until the terms expire in the first quarter of 2028. The level of these commitments will generally be reduced at a per ton rate as such rail and export terminal services are utilized against the required minimum tonnage amounts over the contract term stipulated in such rail and export terminal contracts. However, as of December 31, 2025, the Company had no expected volume shortfall resulting in a need for an accrued liability.

*Litigation*— From time to time, we are subject to various litigation and other claims in the normal course of business. Losses related to such contingencies are accrued when/if loss is probable and the amount is reasonably estimable. No losses have been accrued in the consolidated financial statements with respect to such matters. Losses from certain injury-related matters are reasonably possible of occurring; however, an estimate of the possible range of loss cannot be made at this time as no litigation has progressed sufficiently through discovery and development of important facts and legal issues at this time. While it is possible that liability will be assessed against us in the preparation plant purchase matter discussed below, we deem that possibility to be remote.

*Preparation Plant Purchase*

In February 2024, we purchased a Preparation Plant (the “Plant”) from EMCOAL, Inc. for $3 million. After this purchase, the Plant was disassembled and transported to the Maben Complex for reassembly. On November 15, 2024, Justice Coal of Alabama, LLC (the “Plaintiff”) filed a complaint in the United States District Court for the Southern District of West Virginia, Beckley Division, against Ramaco Resources, Inc., Ramaco Development, LLC, and Maben Coal LLC. On May 5, 2025, the United States District Court for the Southern District of West Virginia granted our Motion to Transfer Venue to the United States District Court for the Northern District of Alabama. On June 3, 2025 Plaintiff amended its Complaint to add EMCOAL, Inc. as a Defendant.

Plaintiff claims their sale of the Plant to EMCOAL, Inc. was not completed and thus EMCOAL, Inc. did not have the right to sell the Plant to us. As a result of Ramaco purchasing the Plant from EMCOAL, Inc., Plaintiff claims in the complaint we are liable for conversion, unjust enrichment, and negligence. Plaintiff has sought damages for these alleged claims. We filed a motion to dismiss Plaintiff’s Amended Complaint against us on June 24, 2025 and that motion was subsequently denied. We filed our Answer to the Amended Complaint on November 21, 2025. The Court has directed the Parties to be ready for trial “by December 2026” with the trial date to be set in a subsequent Scheduling Order. We believe we have meritorious defenses to all claims in this matter.

*Storage Silo Partial Failure*

On November 5, 2018, one of our three raw coal storage silos that fed our Elk Creek plant experienced a partial structural failure. A temporary conveying system completed in late-November 2018 restored approximately 80% of our plant capacity. We completed a permanent belt workaround and restored the preparation plant to its full processing capacity in mid-2019. Our insurance carrier, Federal Insurance Company, disputed our claim for coverage based on

certain exclusions to the applicable policy and, therefore, on August 21, 2019, we filed suit against Federal Insurance Company and Chubb INA Holdings, Inc. in Logan County Circuit Court in West Virginia seeking a declaratory judgment that the partial silo collapse was an insurable event and to require coverage under our policy. Defendants removed the case to the United States District Court for the Southern District of West Virginia, and upon removal, we substituted ACE American Insurance Company as a defendant in place of Chubb INA Holdings, Inc. The trial in the matter commenced on June 29, 2021, in Charleston, West Virginia.

On July 15, 2021, the jury returned a verdict in our favor for $7.7 million in contract damages and on July 16, 2021, made an additional award of $25.0 million for damages for wrongful denial of the claim under *Hayseeds, Inc.* *v. State Farm Fire & Cas.*, 177 W. Va. 323, 352 S.E. 2d 73 (W. Va. 1986), including inconvenience and aggravation. On August 12, 2021, the defendants filed a post-trial motion for judgment as a matter of law or in the alternative to alter or amend the judgment or for a new trial. On March 4, 2022, the court entered its memorandum opinion and order on the motion reducing the jury award to a total of $1.8 million, including pre-judgment interest, and also vacated and set aside, in its entirety, the jury award of *Hayseeds* damages. The same day, the court entered the judgment in accordance with the memorandum opinion and order.

On April 1, 2022, we filed a notice of appeal with the U.S. Court of Appeals for the Fourth Circuit. On July 20, 2023, the court rendered a decision reinstating the jury’s $7.7 million contract damages verdict. The court further determined that we are entitled to attorney fees in an amount to be determined on remand. Finally, the court held that we are entitled to *Hayseeds* damages for wrongful denial of the claim but remanded for a new trial on the amount of such damages after affirming that the original $25 million award was excessive. On August 3, 2023, the Defendants-Appellees filed a Petition of Rehearing and Rehearing *En Banc* with the Fourth Circuit. The petition was denied by order dated August 15, 2023. On August 29, 2023, the court clarified that the amount of attorney’s fees to be determined on remand included appellate fees. On September 8, 2023, the court entered its amended judgment, which awarded post-judgment interest on the previously awarded and reinstated verdict related to contract (compensatory) damages and the Fourth Circuit thereafter issued its mandate on October 2, 2023. On August 19, 2024, the Court issued a Memorandum Opinion and Order that the Hayseeds damages to be considered in the new trial would include annoyance and inconvenience up to October 2, 2023 with new discovery permitted for the time period of July 15, 2021 through October 2, 2023. The Court also ordered Hayseeds damages to be considered for net economic loss caused by the defendant’s delay in settlement be allowed for the time period of July 15, 2021 through October 2, 2023 with new discovery to be permitted for that time period.

The defendants fully paid the portion of the judgment related to contract (compensatory) damages in the court’s order and that portion of the matter is considered closed. The Company recognized a $7.8 million gain during 2023, which was recorded in *Other income (expense), net* on the Consolidated Statements of Operations. Of this amount, $2.0 million was included in Insurance proceeds related to property, plant, and equipment as part of investing activities on the Consolidated Statements of Cash Flows and the remaining amount was included in operating activities. On April 24, 2024, the Court stated Ramaco is entitled to reasonable attorney fees for both the appeal and the first trial, adding there will be a full Hayseeds trial under the timelines set forth above. Regarding the court’s determination and award of attorney’s fees, the Company accrued an additional loss recovery asset of approximately $0.8 million during 2025, bringing the total loss recovery asset to approximately $4.7 million in *Prepaid expenses and other* on the Consolidated Balance Sheets as of December 31, 2025. The corresponding reduction of $0.8 million during 2025 was to *Selling, general, and administrative expense* on the Consolidated Statements of Operations. The Company considers that it is probable to recover at least this amount of previously recognized attorneys’ fees expenses based upon the developments above.

The matter is now pending before the District Court for a new trial for *Hayseeds* damages, as well as the court’s determination and award of attorney’s fees. The trial date originally set for July 15, 2025 has been continued and we are currently awaiting a new scheduling order from the court.

*Class Action Complaint for Violations of the Federal Securities Laws*

On January 30, 2026, a putative class action complaint was filed against the Company, Randall Atkins, our Chief Executive Officer, and Jeremy Sussman, our Chief Financial Officer, alleging violations of Sections 10(b) and

20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder arising from allegedly materially false and/or misleading statements concerning the development and active mining status of the Company's Brook Mine rare earth and critical minerals project in Wyoming during the class period of July 31, 2025 through October 23, 2025. The plaintiff seeks determination of class action status under Rule 23 of the Federal Rules of Civil Procedure, an award of compensatory damages against all defendants jointly and severally for all damages sustained (including interest), reasonable costs and expenses including counsel fees and expert fees, and such other relief as the court deems just and proper.

The case is pending in the United States District Court for the Southern District of New York and is captioned *Lynn Henning, Individually And On Behalf Of All Others Similarly Situated v. Ramaco Resources, Inc., Randall W. Atkins, And Jeremy R. Sussman, (Case No. 1:26-cv-00846)*. We believe we have meritorious defenses to all claims in this matter.

### NOTE 10—REVENUES

Our revenue is derived from contracts for the sale of coal and is recognized when the performance obligations under the contract are satisfied, which is at the point in time control is transferred to our customer. Generally, domestic sales contracts have terms of approximately one year and the pricing is typically fixed. Export sales have spot or term contracts, and pricing can be either fixed or derived against index-based pricing mechanisms. Sales completed with delivery to an export terminal are reported as export revenue.

Disaggregated information about Revenue by segment is presented below:

​

| (In thousands) | Year ended December 31, 2025 | Year ended December 31, 2024 | Year ended December 31, 2023 |
| --- | --- | --- | --- |
| Metallurgical Coal Segment |  |  |  |
| Coal Sales |  |  |  |
| North American revenue | $196,963 | $221,664 | $227,484 |
| Export revenue, excluding Canada | 339,655 | 444,631 | 466,040 |
| Total revenue | $536,618 | $666,295 | $693,524 |

​

Annual revenues for 2025 include less than a $0.1 million net decrease to revenue related to adjustments for performance obligations satisfied in a previous reporting period. These adjustments were due to true-ups of previous estimates for provisional pricing and demurrage as well as price adjustments for minimum specifications or qualities of delivered coal.

As of December 31, 2025, the Company had outstanding performance obligations of approximately 1.1 million tons for contracts with fixed sales prices averaging $142 per ton as well as 1.2 million of additional tons for contracts with index-based pricing mechanisms. The Company expects to satisfy approximately 97% of the committed tons in 2026 and the remainder in 2027. Variable amounts, including index-based prices, have not been estimated for the purpose of disclosing remaining performance obligations as permitted under the revenue recognition guidance when variable consideration is allocated entirely to a wholly unsatisfied performance obligation.

Sales into individual foreign countries equaling or exceeding 10% of our total revenues for 2025 included Germany, which represented 11% of 2025 revenues. Sales into India and Germany were 11% and 10%, respectively, of 2024 revenues. Sales into Germany, Canada, and Brazil were 14%, 14%, and 10%, respectively, of 2023 revenues. The Company used the final export destination of the goods as the basis for these disclosures.

The Company has not recorded any revenues from the Rare Earths and Critical Minerals Segment.

### **NOTE 11—RELATED PARTY TRANSACTIONS**

*Legal Services*—Some of the professional legal services we receive are provided by Jones & Associates (“Jones”), a related party. Legal services incurred for Jones in 2025, 2024, and 2023 totaled less than $0.1 million, $0.1 million, and zero, respectively. Mr. Jones subsequently became the Company’s General Counsel on May 1, 2025.

​

*Ramaco Foundation*—During 2025, the Company made a charitable cash contribution of $0.5 million to the Ramaco Foundation, which was recognized in *Other income (expense), net*, on the Consolidated Statements of Operations. The Ramaco Foundation is an unconsolidated not-for-profit organization whose board of directors includes several members of the Company’s management and board of directors.

*Other Professional Services—*The Company has also entered into professional services with four other related parties, which have been aggregated due to immateriality. Professional services incurred for these related parties were $0.2 million, $0.2 million, and $0.3 million in 2025, 2024, and 2023, respectively.

### NOTE 13—EARNINGS (LOSS) PER SHARE

Earnings per share (“EPS”) is not presented retrospectively for periods prior to the issuance of the tracking stock as the tracking stock was not a part of the Company’s capital structure during those periods and the issuance of the tracking stock changes the common shareholders’ relative residual interest in the Company. Therefore, EPS is presented for the Company’s single class of common stock up to the time the tracking stock was issued. EPS is presented prospectively under the two-class method starting on the date of initial distribution of the tracking stock. Refer to Note 8 for information related to the Company’s tracking stock.

​

​

Unvested restricted stock awards have the nonforfeitable right to receive cash dividends on the same basis as common shares; therefore, unvested restricted stock is considered a participating security for the purpose of calculating EPS. Prior to the issuance of Class B common stock, the Company presented its EPS for its common stock and unvested restricted stock on a combined basis since both instruments participated in net earnings on the same basis and the resulting EPS is typically the same. Starting under the two-class method, the Company reports separately the net earnings allocated away from holders of Class A and Class B common stock to holders of unvested restricted stock awards.

​

Unvested restricted stock units and performance stock units include forfeitable dividend rights that are subject to the vesting conditions of the underlying awards; therefore, these awards are not considered participating securities and should not be allocated undistributed earnings for the purpose of calculating EPS. However, dividends or dividend equivalents declared and charged to retained earnings for these awards reduce the amount of net earnings available for distribution to common stockholders and should be reflected as such under the two-class method.

​

As described in Note 8, the Company declared a non-cash dividends to Class A shareholders in 2024 and 2025, which resulted in the issuance shares of Class B common shares. Since the dividends involved different classes of common stock, the distributions of the shares were accounted for prospectively for EPS purposes and the non-cash dividends were attributed to Class A net earnings under the two-class method. The December 5, 2024 non-cash dividends to Class A shareholders in the form of Class B common shares were not issued and were not determinable at December 31, 2024 such that the Company estimated the number of Class B common shares and unvested awards for Class B diluted EPS purposes at that time.

​

The Company also declared non-cash dividends to Class B shareholders during 2024 and 2025, which resulted in the issuance of Class B common shares. Since the Class B shareholders’ proportional interest in the Company’s overall net assets did not remain the same after each issuance, the distribution of these shares were accounted for prospectively for EPS purposes and non-cash dividends were attributed to Class B net earnings under the two-class method.

​

For accounting purposes, Class B’s participation rights in net earnings are, in substance, discretionary based on the power of the Company’s Board of Directors to add or modify expense allocation policies, redefine CORE assets, and redetermine CORE’s per-ton usage fees at any time, in its sole discretion, without shareholder approval. Therefore, no amount of the Company’s net earnings shall be allocated to Class B for the purpose of calculating EPS other than actual cash dividends declared during the period for the tracking stock. However, during 2025, dividends declared by the Company were in excess of consolidated net income, which resulted in an undistributed net loss for reporting purposes. The resulting undistributed net loss was allocated proportionately between outstanding Class A and Class B common stock based on the rights to residual net assets upon liquidation being equal between holders of Class A and Class B common stock. Refer to Note 8 for information regarding dividends declared on Class B common stock.

​

Diluted EPS was calculated using the treasury stock method for stock options and restricted stock units. For performance stock units, the awards were first evaluated under the contingently issuable shares guidance, which requires a determination as to whether shares would be issuable if the end of the reporting period were the end of the contingency period. For shares determined to be issuable under performance stock unit awards, the treasury stock method was then applied to determine the dilutive impact of the awards, if any. Unvested restricted stock awards are considered potential common shares as well as participating securities, as discussed previously, and were included in diluted EPS using the more dilutive of the treasury stock method or the two-class method. Since these awards share in cash dividends on a 1:1 basis with common shares, applying the treasury stock method would be antidilutive compared to the basic EPS calculation that allocates earnings to participating securities under the two-class method discussed previously.

​

As discussed in Note 8, the Board of Directors retains the ability, in its sole discretion, to exchange all outstanding shares of Class B common stock into Class A common stock based on an exchange ratio determined by a 20-day trailing volume-weighted average price for each class of stock. The conversion right was evaluated for diluted EPS purposes under the if-converted method, which determines the potential dilutive effect, if any, on Class A shareholders assuming that conversion occurs. The hypothetical conversion assumed to have occurred would have resulted in the issuance of approximately 7.2 million shares and potential common shares and 8.0 million shares and potential common shares of Class A common stock for 2025 and 2024, respectively, based on year-to-date outstanding averages for those years, and would have effectively redistributed Class B’s net earnings to Class A.

​

The hypothetical conversion of Class B common stock into Class A common stock, as discussed above, was excluded from the EPS calculation for each period presented as the effect would have been antidilutive. In addition, antidilutive shares excluded from the dilutive EPS calculation are presented below:

​

| Line item | Years ended December 31, 2025 / Class A | Years ended December 31, 2025 / Class B | Years ended December 31, 2024 / Class A | Years ended December 31, 2024 / Class B |
| --- | --- | --- | --- | --- |
| Antidilutive options | 498,712 | 108,697 | - | - |
| Antidilutive RSUs | 1,109,161 | 71,464 | 313,382 | 4,325 |
| Antidilutive PSUs (at target) | 1,513,438 | 273,383 | 315,941 | 4,361 |
| Antidilutive convertible senior notes | 7,835,169 | - | - | - |

​

​

Diluted EPS for the period from January 1, 2023 through June 20, 2023, the period for which a single class of common stock existed, excluded all outstanding restricted stock units, or 684 thousand units in total, because the effect would have been antidilutive. In addition, diluted EPS for the same period excluded outstanding performance stock units originally granted in 2022, or 249 thousand units at target, based on the guidance for contingently issuable shares. For the period from June 21, 2023 through December 31, 2023, the hypothetical conversion of Class B common stock into Class A common stock was immaterial, and no other potential common shares were excluded from the computation of diluted EPS for either class of common stock.

### NOTE 14—SEGMENT REPORTING

Pursuant to ASC 280, operating segments are defined as components of an enterprise engaged in business activities from which it may recognize revenues and incur expenses, about which discrete financial information is available and evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance.

During the third quarter of 2025, the Company modified its segment structure largely as a result of activity at the Brook Mine during the period. Beginning with the third quarter of 2025, the Company’s reportable segments, which are primarily based on the Company’s internal organizational structure and types of controlled mineral deposits, are its two operating segments—Metallurgical Coal and Rare Earths and Critical Minerals (no operating segments have been

aggregated). In conjunction with this change, prior period amounts have been recast to conform to this new segment reporting structure.

The Metallurgical Coal segment operates and develops high-quality, low-cost metallurgical coal in southern West Virginia and southwestern Virginia. The Metallurgical Coal segment generates revenue primarily through the production of metallurgical coal for sale to the steel industry. The Metallurgical Coal segment also generates revenue through the sale of coal purchased from third parties.

The Rare Earths and Critical Minerals segment operates the Brook Mine complex located in Sheridan, Wyoming, where the Company is developing rare earth and critical mineral operations in addition to performing initiatives related to coal-to-carbon based products and materials. The Brook Mine is expected to be a future producer of refined rare earth and critical mineral products. No revenues have been recognized from the Rare Earths and Critical Minerals segment.

The Company’s CODM, the chief executive officer, regularly reviews financial information at the segment level for the purpose of allocating resources and assessing operating results and financial performance. The CODM uses Segment Adjusted EBITDA as management’s primary segment measure of profit or loss in assessing segment performance and deciding how to allocate the Company’s resources. This measure enables the CODM to evaluate operational efficiency and segment performance by comparing current results to historical data, while also monitoring variances between actual results and forecasts to inform decisions on capital, personnel and other resource allocations across segments. Segment Adjusted EBITDA is calculated as segment revenues less significant segment expenses, specifically, cost of sales (excluding transportation costs), transportation costs and selling, general and administrative expenses (excluding stock-based compensation expense), as well as certain other segment items. Significant segment expenses and other segment items also exclude certain costs that are non-recurring, non-cash or are not related to the segments’ underlying business performance. A reconciliation of total Segment Adjusted EBITDA to consolidated income or loss before income taxes is included in the tables below.

Certain current period costs are incurred at the corporate level and are allocated to the Company’s segments. These costs generally include shared service functions such as legal, information technology, finance and accounting, sales, and executive management. Each allocation is measured differently based on the specific facts and circumstances of the costs being allocated that are deemed to best represent the expected benefit received by the operating segment. The remaining unallocated corporate costs that are not attributed to the operating segments are reported within Corporate expenses and other as a reconciling item to our consolidated results. Our allocation methodology is periodically evaluated and may change. A similar allocation of shared service functions is not presented within the recasted prior period information as the benefit to the respective operating segment is not comparable to the current period. The expenses associated with these shared service functions are presented within the Metallurgical Coal segment in the prior period.

As the Company’s CODM manages the Company’s assets on a consolidated basis, the CODM is not regularly provided asset information for the reportable segments. The Company does not have any material long-lived assets located outside of the United States. For all of the periods presented below, (i) the Company’s revenues were derived from U.S.-domiciled operations, and (ii) the Company did not have any intersegment revenues.

The CODM does not regularly review segment asset information at a different asset level or category than those disclosed within the Consolidated Balance Sheets for the purpose of assessing performance and making resource allocation decisions.

The following tables present the Company’s reportable segment information:

### NOTE 15—SUBSEQUENT EVENTS

On February 25, 2026, the Company announced that the Board of Directors declared a stock dividend of $0.1489 per share on the Company’s Class B common stock to be payable on March 27, 2026 to shareholders of record on March 13, 2026. Given that this payment will occur in the form of Class B shares, Class B holders will receive a number of shares of Class B common stock for each share of Class B common stock determined by dividing $0.1489 by the closing transaction price of the Class B common stock on March 13, 2026.

* * * * *

## Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

## Item 9A. Controls and Procedures

*Management’s Evaluation of Disclosure Controls and Procedures.* As of December 31, 2025, our management, under the supervision and with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures in pursuant to applicable Exchange Act rules. Based upon this evaluation, our principal executive officer and principal financial officer have concluded that, as of December 31, 2025, the disclosure controls and procedures were effective at a reasonable assurance level.

​

*Management’s Annual Report on Internal Control over Financial Reporting.* Management is responsible for establishing and maintaining adequate internal control over financial reporting. Management used the criteria described in *Internal Control-Integrated Framework* *(2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) to evaluate the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025. Management has concluded that, as of December 31, 2025, the Company’s internal control over financial reporting is effective based on the criteria set forth in the COSO framework.

​

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in their report, which is included herein and expressed an unqualified opinion.

​

*Remediation of Previously Reported Material Weakness.* A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company's annual or interim financial statements will not be prevented or detected on a timely basis. Management concluded that a material weakness existed as of December 31, 2024 related to an insufficiency of appropriately qualified and trained professionals to perform certain control activities necessary to achieve our control objectives. The material weakness also resulted in incomplete or inadequate documentation related to accounting policies and procedures, inappropriate conclusions reached regarding non-routine accounting matters, and insufficient evidence of internal control activities. In response to the previously reported material weakness, we developed a comprehensive plan of remediation, which included assessing, redesigning, and implementing modifications of our internal controls, and hiring of additional qualified accounting personnel, or supplementing internal resources with qualified external advisors as needed. We implemented these remediation efforts during 2025 and we completed the testing of the design and operating effectiveness of the respective controls. Based on the results of our testing, as of December 31, 2025, we concluded that the controls are adequately designed, implemented, and have operated effectively for a sufficient period of time to remediate this previously reported material weakness.

​

*Changes in Internal Control Over Financial Reporting.* During 2025, we took substantial steps to improve our control environment by executing our remediation plan to address the previously reported material weakness, as described above. Except as described above, there were no significant changes in our internal control over financial reporting during our fourth quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Notice**

Weir International, Inc. (WEIR) was retained by Ramaco Resources, Inc. (Ramaco, NASDAQ: METC, METCB) to prepare a Technical Report Summary (TRS) related to Ramaco’s Brook Mine located near Sheridan, Wyoming. This TRS serves as a revision to a TRS dated September 17, 2025, effective June 30, 2025, and filed on February 26, 2026 (September 2025 TRS). This revised TRS updates the effective date to December 31, 2025 with respect to assumptions and the knowledge of Qualified Persons (QPs) and it supersedes all prior technical reports filed by the registrant concerning this property. This revision is prepared in response to comment letters received from the United States Securities and Exchange Commission (SEC) and serves to address requests for additional information and/or clarification. This TRS maintains the modeling data cut-off date of June 30, 2025 used in the September 2025 TRS.

This report provides an Initial Assessment of Ramaco’s critical mineral deposit located within the Brook Mine. This TRS has been prepared in accordance with the SEC Regulation S-K 1300 for Mining Property Disclosure (S-K 1300) and 17 Code of Federal Regulations (CFR) § 229.601(b)(96)(iii)(B) reporting requirements. This report was prepared for Ramaco, and its affiliates.

This report was prepared by WEIR and Ramaco personnel who meet the SEC’s definition of QPs, with sufficient experience in the relevant type of mineralization and deposit under consideration in this report. WEIR is a third-party firm comprising mining experts. In preparing this report, WEIR relied upon data, written reports and statements provided by Ramaco. WEIR has taken all appropriate steps, in its professional opinion, to ensure the information provided by Ramaco is reasonable and reliable for use in this report.

This Technical Report Summary has been prepared for the purpose of supporting disclosures pursuant to Regulation S-K 1300 and should not be construed as an independent valuation of the mineral property, the issuer, or the issuer’s securities.

The estimates and projections presented in this report are based on geological, engineering, economic, and other information available as of the effective date of this report. While the QPs consider the estimates and assumptions used herein to be reasonable, additional data, changes in operating conditions, market factors, regulatory requirements, or other circumstances may result in revisions to the estimates and conclusions presented, which may be material.

Certain information contained in this report constitutes forward-looking information, including, but not limited to, estimates of mineral resources, production forecasts, operating and capital cost estimates, economic analyses, and mine plans. Forward-looking information is based on assumptions believed to be reasonable at the time of preparation; however, actual results may differ materially from those

projected. The assumptions and factors affecting such forward-looking information are discussed throughout this report.

**1.0** **Executive Summary**

WEIR was retained by Ramaco (Nasdaq: METC) to prepare this TRS which provides an Initial Assessment of Ramaco’s critical mineral and coal deposit located within its Brook Mine. The Brook Mine is located within Ramaco’s mineral holdings located approximately seven miles north of Sheridan, Wyoming.

This TRS serves as a revision to a TRS dated September 17, 2025, effective June 30, 2025, and filed on February 26, 2026. This revised TRS updates the effective date to December 31, 2025 with respect to assumptions and the knowledge of Qualified Persons (QPs) and it supersedes all prior technical reports filed by the registrant concerning this property. This revision is prepared in response to comment letters received from the United States Securities and Exchange Commission (SEC) and serves to address requests for additional information and/or clarification. This TRS maintains the resource modeling data cut-off date of June 30, 2025 used in the previous TRS.

This report has been prepared in accordance with the SEC Regulation S-K 1300 for Mining Property Disclosure (S-K 1300) and 17 Code of Federal Regulations (CFR) § 229.601(b)(96)(iii)(B) reporting requirements for a TRS.

**1.1** **Property Description**

Ramaco’s Brook Mine is located within Ramaco’s mineral holdings located approximately seven miles north of Sheridan, Wyoming in Sheridan County. The Brook Mine is situated in the Sheridan Coal Field in the northwestern portion of the Powder River Basin (PRB) coal producing region of the United States (see Figure 1-1). The United States Geological Survey (USGS) 7.5-minute quadrangle maps are Acme, Hultz Draw, Monarch, and Sheridan.

The Brook Mine consists of approximately 15,800 acres of Ramaco controlled surface and mineral holdings located in Sheridan County, Wyoming. Ramaco acquired the Brook Mine in 2011 from the Sheridan-Wyoming Coal Company (SWCC). SWCC retained a nonparticipating coal royalty in the amount of $0.10 per clean coal ton. When Ramaco began development of the Brook Mine in 2012, Ramaco originally permitted approximately 4,500 acres that it regarded as the optimal area for a new surface coal mine. As Ramaco began further core drilling exploration in 2021 and 2022 relative to critical mineral exploration, Ramaco continued to drill in areas within the original coal mining permit boundary in order to leverage the existing drill core available for sampling.

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

As a result of the drilling concentration within the current coal mining permit boundary, the current Brook Mine Mineral Resource falls generally within the aerial extent of the existing coal mining permit boundary. This surface area represents less than 30 percent of the total acreage controlled by Ramaco in and around the Brook Mine.

Ramaco owns 93 percent of the mineral rights and controls the remaining 7 percent associated with the Brook Mine Mineral Resource estimate described in this TRS. Ramaco intends to purchase the remaining 7 percent un-owned portion of mineral rights. Acquisition costs have been included in the financial model in lieu of mineral royalties. Ramaco also owns 40 percent of the surface property with the balance controlled through surface access agreements and leases. The Burlington Northern Santa Fe (BNSF) Railroad and Interstate 90 are located along the southern boundary of the Brook Mine’s permit area.

Significant property encumbrances include: (i) the Laya coal lease area, excluded from resource estimation as the lease does not expressly provide the right to extract critical mineral oxides (CMO); (ii) a portion of the Padlock Surface Use Agreement area is subject to a surface mining restriction; and (iii) various railroad, highway, utility, and oil-and-gas rights-of-way with minimal impact on the current resource boundary. Ramaco holds no royalty interest in any property owned or operated by another party.

All existing permits for development of the Brook Mine are active and current for surface coal mining. A revision to the Mining and Reclamation Plan in the existing permit (WDEQ/LQD Permit No. 841-T1) will be required to specifically authorize CMO extraction and associated processing and tailings facilities.

**1.2** **Geological Setting and Mineralization**

The regional geology of this area is characterized by a sequence of sedimentary rocks that formed during the Late Cretaceous to early Paleocene Period. The stratigraphic sequence consists of interbedded sandstones, mudstones, and coal seams that were deposited in fluvial, deltaic, and lacustrine environments.

The primary coal seams that are associated with CMOs in the Brook Mine, in descending stratigraphic order, are the Dietz 1, Dietz 2, Dietz 3, Monarch, Upper Carney, Lower Carney, and Masters. There are also seven unnamed minor coal seams lying below the Masters Seam. The CMOs are understood to have been incorporated into the coal during its formation and are found in association with clay minerals and organic matter in the coal seams. The adjacent interburden strata directly above and below the coal seams contain elevated levels of CMOs, primarily in clays, carbonaceous clays, shales, and siltstones.

The United States Department of Energy National Energy Technology Laboratory (NETL) has proposed that CMOs may have migrated upward from depth through heated circulating fluids, leaching CMOs from primary source minerals and re-precipitating them at geochemical transition boundaries (coal-to-clay interfaces and pH/temperature gradients). This mechanism is consistent with the elevated concentrations observed at seam contacts.

For the purposes of this TRS, Mineral Resource estimation is limited to coal and seven Targeted Critical Minerals (TCMs) that have been determined to have reasonable prospects for economic extraction: dysprosium, gallium, germanium, neodymium, praseodymium, scandium, and terbium.

Summary statistics on an elemental basis for each of the TCMs from the drill hole assay database are shown in Table 1-1.

​

**Table 1-1****Brook Mine TCM Sample Statistics**

**1.3** **Exploration**

Ramaco’s exploration program for CMOs at the Brook Mine has evolved from an initial NETL-partnered characterization effort in 2019 into a systematic grid-based delineation drilling program. A summary of the Brook Mine drilling programs is provided in Table 1-2.

**Table 1-2****Brook Mine Drilling Programs**

Ramaco’s CMO exploration has primarily relied on diamond core drilling on an approximate 1,000-foot north-south grid. Core recovery of 90 percent or greater are required; holes with lower recovery in targeted intervals are reviewed and may be excluded from grade modeling. Portable X-ray fluorescence (pXRF) screening of core was used to identify intervals for submission to ICP-MS assay laboratories. All geological, geophysical, and assay data are stored on a Ramaco server.

As of the June 30, 2025 data cutoff, the Brook Mine database includes 615 drill holes (including 417 historical Big Horn Coal rotary/cored holes adopted into the database), of which 128 holes contained ICP-MS CMO assay data comprising 5,903 individual sample analyses. The 128 CMO-assayed holes form the primary basis for the TCM block model and Mineral Resource estimate.

​

In the second half of 2025, Ramaco initiated a test mining pit in the south-central portion of the Brook Mine targeting the Dietz and Carney seams. This program yielded 185 channel samples and 162 bulk samples (approximately one ton each). Analysis of these samples was received in 2026 and, as results post-date the June 30, 2025 data cutoff, these samples are not incorporated into the resource model presented in this TRS. WEIR has reviewed the channel and bulk sample data and concludes that the results generally support the continuity of TCM grade across larger sampling areas.

Hydrogeological and geotechnical data programs supporting mine design are summarized in Sections 7.3 and 7.4 of this TRS. Groundwater monitoring (Carney and Masters seam wells, alluvium wells, underburden wells) has been active since 2013. Current data are appropriate for the permitted highwall mining configuration; additional hydrogeological characterization will be required as the mine plan advances to a deeper truck-and-shovel open-pit layout.

**1.4** **Development**

The Brook Mine, as proposed in this TRS, will be developed as a conventional truck-and-shovel open-pit mine. Overburden and TCM Resources will be excavated by large hydraulic shovels and loaded into haul trucks. Waste material will be managed in external spoil piles with future potential for in-pit placement as mining advances. Blasting will be required for overburden removal however, dozers are expected to rip TCM Resources to facilitate selective loading and minimize dilution.

The conceptual Life-of-Mine (LOM) Plan is based on a revenue-factor 0.68 pit shell and encompasses approximately 1.09 billion tonnes of total material that would be mined over a 40-year production period. The operation targets a steady-state TCM process plant feed of approximately 2.63 million tonnes per annum (Mtpa). Mining commences in the northwest portion of the resource area and advances southeast and eastward through a series of nested pit phases.

Coal Resources will be mined concurrently with the TCM Resource and sold as a direct-shipped run-of-mine (ROM) thermal coal product without additional processing. The mine will require a total workforce of approximately 190 personnel (70 mine, 100 processing, 20 G&A) at full production.

The LOM Plan pit extents in conjunction with the TCM Resource pit extents are shown in Figure 1-2.

A multi-stage hydrometallurgical leaching process has been designed to recover TCMs from ROM feed material. The proposed flowsheet includes feed handling and comminution (mineral sizers and open-circuit ball mill), pretreatment, primary and secondary leaching and filtration, impurity removal via precipitation and ion exchange, and rare earth separation via solvent extraction. Gallium and germanium are recovered via selective solvent extraction in parallel circuits. The process plant is designed for a ROM throughput of 2.63 Mtpa and estimated power consumption of 9.3 MW. Filtered (dry-stack) tailings management is planned; heap leaching is not proposed.

Key infrastructure is detailed in Sections 4 and 15 of this TRS. The Brook Mine benefits from existing highway (I-90, US-87) and BNSF rail access, proximity to the Sheridan labor market, and established power supply from Montana-Dakota Utilities (MDU).

**1.5** **Mineral Resource Estimate**

Mineral Resources for the Brook Mine are current as of December 31, 2025 (geological modeling data cutoff: June 30, 2025) and classified in accordance with SEC Regulation S-K Item 1302(d)(1)(iii)(A). All Mineral Resources are reported in the Inferred category. There are no Measured or Indicated Mineral Resources.

The Inferred classification reflects: (i) a sample spacing wider than what WEIR considers necessary to demonstrate the geological and grade continuity required for an Indicated classification; and (ii) the early-stage nature of metallurgical and economic studies at the Initial Assessment level.

Resources were constrained within a Revenue Factor 1.0 pit shell generated by Datamine Studio NPVS pit optimization using the commodity prices, processing recoveries, and cost parameters described in Section 11 of this TRS. A Net Smelter Return (NSR) marginal TCM cutoff of $67.69 per tonne was applied to classify TCM resources. All resources are reported on an in-situ (in-place) basis.

Pricing and recovery estimates for the seven TCM oxides and thermal coal (by-product) considered in the Resource estimate are summarized in Table 1-3:

**Table 1-4****In-Place TCM Resource Tonnage and Grade Estimate, as of December 31, 2025**

Notes:

- Coal and TCM resources are considered collectively in the evaluation of reasonable prospects of economic extraction with estimated revenues as follows: $850/kg Dy2O3, $770/kg Ga2O3, $2,435/kg GeO2, $130/kg Nd2O3, $130/kg Pr6O11, $3,750/kg Sc2O3, $3,000/kg Tb4O7, and $13.23/tonne coal.
- TCM processing recoveries are as follows: 82% Dy2O3, 67% Ga2O3, 94% GeO2, 92% Nd2O3, 92% Pr6O11, 70% Sc2O3, 94% Tb4O7. An overall recovery of 90 percent was applied to the coal.
- Mining costs of $1.33 per tonne were used for resource pit shell generation. A mining cost adjustment factor (MCAF) of 0.90 was used for TCM and waste rock types to account for the 45X production tax credit assumed.
- A Net Smelter Return (NSR) marginal TCM cutoff of $67.69 per metric tonne of rock was used to classify TCM resources as an Inferred Mineral Resource within the optimized pit shell. The marginal TCM cutoff consists of $69.80 per tonne of processing costs, $1.44 per tonne of G&A and $3.97 per tonne of TCM residue handling costs as well as an offset to the costs of 10 percent (-$7.52 per tonne) from the 45X production tax credit. *NSR* = (69.80 + 1.44 + 3.97) × (1 − 10%)
- TCM Resources were constrained within the revenue factor 1.0 pit shell described in Section 11.2.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

- Mining costs of $1.33 per tonne were used for resource pit shell generation. A mining cost adjustment factor (MCAF) of 0.90 was used for TCM and waste rock types to account for the 45X production tax credit assumed.
- The effective marginal cutoff for coal resources is $0.05/tonne consisting of coal selling costs. Coal is sold as ROM product, and no additional processing is planned.
- A minimum seam thickness of two feet and the revenue factor 1.0 pit shell described in Section 11.2 were used to constrain the coal Inferred Resources.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

The Mineral Resources reported herein are not Mineral Reserves and do not have demonstrated economic viability. The estimate is classified entirely as Inferred and is considered too speculative geologically to have the economic considerations applied that would enable conversion to Mineral Reserves. There is no certainty that any part of an Inferred Mineral Resources will ever be converted to Mineral Reserves. However, WEIR has a reasonable expectation that the majority of the Inferred Mineral Resources could be upgraded to Indicated or Measured Mineral Resources with continued exploration. Quantity and grade estimates have low confidence by definition.

**1.6** **Economic Evaluation**

A preliminary discounted cash flow (DCF) economic analysis was conducted as part of this Initial Assessment to confirm reasonable prospects of economic extraction for the Brook Mine. The financial model was prepared by Mr. Woloschuk, P.Eng. (QP), based on the conceptual LOM mine plan developed by WEIR, cost estimates prepared by Fluor Enterprises, Inc. (Fluor)

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

and Mr. Woloschuk, and commodity pricing supported by internal and third-party western market studies.

The model is structured on an annual basis over a 40-year LOM in real (constant-dollar) terms, excluding project financing costs. Key model parameters include: steady-state plant feed of 2.63 Mtpa; weighted average TCM oxide basket price of $1,145/kg oxide equivalent; initial capital expenditure of $579 million (including $106 million contingency; accuracy range -30 percent to +50 percent); LOM total operating cost of approximately $87.70 per tonne of TCM plant feed; and Wyoming state and federal taxes as applicable (no state income tax, 6 percent coal severance, 4 percent coal ad valorem, 4 percent TCM extractive taxes, 21 percent federal corporate tax). Section 45X Advanced Manufacturing Production Tax Credits are incorporated at 10 percent of the TCM mining and processing costs. Applicable coal royalties are included in operating costs.

Key economic metrics from the financial model are summarized in Table 1-6:

**Table 1-6****Economic Analysis Summary**

A sensitivity analysis was conducted on after-tax basis for NPV at an eight percent discount rate (NPV8) and IRR over a +/−20 percent range for commodity prices, capital costs, and operating costs, as presented on Figures 19-1 and 19-2 of this TRS. The key sensitivity metrics are summarized in Table 1-7 below:

​

​ ​

July 24, 2026 Page 11

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 1-7****Sensitivity Metrics**

This economic analysis is an Initial Assessment based entirely (100 percent) on Inferred Mineral Resources. Unlike Mineral Reserves, Mineral Resources do not have demonstrated economic viability. An Initial Assessment cannot be used as the basis for disclosure of Mineral Reserves. The results should be considered preliminary and are subject to risk given the early-stage nature of the project, including the risks detailed throughout this report and summarized in Section 22.2.

**1.7** **Environmental Studies and Permitting Requirements**

Environmental baseline studies for the Brook Mine were conducted in support of WDEQ/LQD Permit to Mine No. 841-T1 (issued July 7, 2020), which covers 4,541 acres and authorizes surface coal mining in Sheridan County, Wyoming. Baseline studies include land-use inventory, cultural resources review, climatology baseline, topography and geologic hazard assessment, comprehensive hydrology baseline (surface and groundwater), soil resources, vegetation inventory, wildlife baseline, wetlands delineation, and alluvial valley floor investigation. These studies represent a regulator-reviewed environmental characterization.

Active permits and environmental authorizations as of the effective date of this TRS include:

- WDEQ/LQD Surface Mining Permit No. 841-T1 (July 7, 2020) - surface coal mining; 4,541 acres; active and current.
- WDEQ/AQD Air Quality Permit No. P0025939 (July 20, 2020) - active and current.
- WYPDES Industrial Stormwater Permit - issued for existing operations.
- MSHA ID# 4801799 - assigned to the planned Brook Mine.

Additional permits and regulatory approvals required prior to CMO mining and processing operations include:

- Revision to Mine Plan Permit No. 841-T1 to specifically authorize CMO extraction, deeper pit development (Masters Seam and below), and revised reclamation plan,

​

​ ​

July 24, 2026 Page 12

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

including updated surety bond sized to cover full reclamation including CMO process plant and tailings.

- WYPDES permit(s) for point-source discharges from the CMO process plant, tailings underdrains, stormwater contact areas, and pit dewatering.
- Air quality permit revision or new permit for CMO processing emissions.
- Additional groundwater monitoring well program (Wall Seam wells) to support future permit revision.

Bonding and Asset Retirement Obligations (ARO):

- Current reclamation bond: approximately $1.47 million (WDEQ bond matrix, as of December 31, 2025).
- Current ARO estimate: $240,475 (as of October 2025). Ramaco plans to update for the LOM Plan once CMO processing and waste management facility designs are completed.
- Preliminary conceptual mine closure cost estimate: approximately $100 million, based on benchmark projects of similar scale and commodity in the region. This estimate will require updating as engineering advances.

There are no anticipated adverse effects on the alluvial valley floor of the Tongue River or other major streams adjacent to the permit boundary. Overburden geochemical analysis indicates no significant acid mine drainage risk. Ramaco has not been cited for any permit non-compliance at the Brook Mine.

The primary pre-mining and approved post-mining land use for the Brook Mine permit area is grazing land. Reclamation will follow coal and TCM extraction to near Approximate Original Contour (AOC) in accordance with WDEQ/LQD permit requirements. An internal Ramaco budget supports advancement through the Preliminary Feasibility Study phase, at which time updated environmental studies, engineering designs, and permitting applications will be prepared.

Ramaco currently employs 12 personnel at the Brook Mine and projects maximum employment of approximately 190 personnel at full production, representing a significant economic contribution to the Sheridan, Wyoming community. No outstanding disputes with local individuals or groups have been identified.

**1.8** **Conclusions and Recommendations**

**1.8.1** **Interpretations and Conclusions**

Based on the geological, technical, and economic work summarized in this TRS, WEIR and Mr. Woloschuk draw the following principal conclusions:

The Brook Mine hosts laterally continuous coal seams together with adjacent carbonaceous claystone, clay, shale, and siltstone intervals that carry TCM mineralization consistent with the Initial Assessment described herein. Geological modeling and block model validation confirm that the Inferred Mineral Resource classification is appropriate given current data density and confidence levels.

Ramaco controls sufficient mineral rights and associated surface access to support the reported Inferred Mineral Resource and the proposed mining operations. Excluded lease and surface-restricted areas have been removed from the resource estimation boundary.

The Brook Mine is favorably situated with respect to infrastructure, including highway and rail access, electric power, water supply, and proximity to the Sheridan community, providing a supportive foundation for project development.

Metallurgical testwork completed to date (bench scale, eight months of testing by Hazen Research; process engineering by Fluor and Hatch) indicates that the TCMs can be recovered using the proposed hydrometallurgical flowsheet based on established unit operations. Testwork is at an early stage and additional optimization, and variability testing are required.

The conceptual open-pit mine plan using conventional truck-and-shovel methods is appropriate for the multi-seam stratigraphic section. The Initial Assessment economics are supported by a positive after-tax NPV at an eight percent discount rate. These results confirm reasonable prospects of economic extraction sufficient to support the Inferred classification.

The Brook Mine is an exploration stage property at an early stage of development. All Resources are Inferred. No Mineral Reserves have been declared, and none can be declared based on an Initial Assessment.

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**1.8.2** **Significant Risks and Uncertainties**

The Brook Mine is subject to risks and uncertainties typical of an early-stage mining project, augmented by the novel nature of coal-hosted TCM mineralization and the proposed recovery process. Key risks include:

- Geological confidence: limited geological evidence of grade or quality continuity associated with Inferred Resources; grade and seam continuity remain to be confirmed with additional infill drilling.
- Metallurgical and process risk: bench-scale testwork is not fully representative of all mineralized domains; additional variability testing and pilot testing is necessary to confirm recoveries and product quality.
- Permitting: revision to existing mining permit required for TCM extraction; additional permits required for processing and tailings facilities; timeline and outcome uncertain.
- Commodity price volatility: TCM prices are subject to significant variability based on supply-demand dynamics, Chinese export policy, and western market developments; pricing may differ from long-term price forecast assumptions used.
- Capital and operating cost uncertainty: Capital expenditure estimate accuracy is -30 percent / +50 percent with a contingency of 25%; actual costs may differ materially as engineering advances.
- Geotechnical and hydrogeological: limited site-specific pit-wall slope-stability data for the revised open-pit design; deeper hydrogeological characterization required.
- Mineral rights: potential need for permit amendment to cover TCM mining rights under existing mineral conveyances; Pine Mountain Oil and Gas holds oil, gas, and coalbed methane rights across the property.

**1.8.3** **Recommendations**

The QPs of this TRS recommend that Ramaco continue to advance the Brook Mine through a focused, integrated program targeting the activities listed in Table 1-8. The program is designed to improve geological confidence, reduce technical risk, and support the economic assumptions

​

​ ​

July 24, 2026 Page 15

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

used in this Initial Assessment, with the objective of advancing the project to a Preliminary Feasibility Study level.

**Table 1-8****Recommended Work Program Summary**

These recommendations should be pursued as an integrated program rather than as isolated technical tasks. Geological drilling, quality assurance and quality control (QA/QC), and geostatistical analysis should proceed in parallel with metallurgical variability testing so that updated resource models, mine plans, and process assumptions can be developed concurrently.

These recommendations are intended to reduce the material risks and uncertainties identified above and to improve the technical basis for future decision-making.

**2.0** **Introduction**

**2.1** **Registrant**

WEIR was retained by Ramaco (Nasdaq: METC) to prepare this TRS which provides an Initial Assessment of Ramaco’s critical mineral and coal deposit located within the Brook Mine. The Brook Mine is located within Ramaco’s mineral holdings located approximately seven miles north of Sheridan, Wyoming.

**2.2** **Terms of Reference and Purpose**

This TRS was prepared specifically for Ramaco’s Brook Mine to support the first-time disclosure of Mineral Resources within the Brook Mine, and it describes the results of an Initial Assessment which supports those Mineral Resources, including a conceptual mine plan, process description, cost estimates, and an economic analysis of the Mineral Resources.

Mineral Resources have been classified in accordance with SEC mining property disclosure rules under Subpart 1300 and Item 601 (96)(iii)(B) of Regulation S-K.

This Initial Assessment is preliminary in nature. It includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied that would enable these Inferred Mineral Resources to be categorized as Mineral Reserves, and there is no certainty that the Initial Assessment will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

This TRS utilizes mixed units of measure as noted. Resource grades are presented in parts per million (ppm) while resource and product tonnages are expressed in Metric Tonnes (tonnes) unless otherwise noted. The primary linear distance units are feet (ft) or miles unless otherwise noted. Currency units are in United States dollars ($) and CMO pricing is presented in United States dollars per kilogram ($/Kg). All costs are presented in United States dollars ($).

Geographical coordinates within this TRS are projected in the Wyoming East Central system utilizing the horizontal North American Datum of 1983 (NAD83) in feet.

For purposes of this TRS, Mineral Resource estimation is limited to a select group of seven CMOs referred to as the TCMs, which have been determined to have reasonable prospects for economic extraction, and are detailed in Table 2-1 as follows:

**2.4** **Details of the Personal Inspection of the Property**

WEIR personnel, including QPs, most recently visited the site on April 28, 2026. WEIR met with various Ramaco personnel at Ramaco’s site office and discussed project status and plans.

While on-site, WEIR personnel conducted interviews with Ramaco Personnel, including its:

- Executive VP - Western Operations
- Senior VP - Engineering & Permitting
- VP - Critical Minerals & Carbon Products
- Field Geologists
- Contract Drillers

During these interviews, WEIR collected information relative to past, present and future exploration plans, sampling practices and procedures, land and mineral rights ownership and control, and other field information to meet regulatory requirements to progress the project.

WEIR personnel visited the Brook Mine site to observe drilling equipment and activities, and general site layout and conditions, including the test pit location. WEIR personnel visited the Ramaco Innovating Carbon Advanced Materials (iCAM) Center, which serves as the Brook Mine field office. WEIR also visited the Brook Mine core logging facility, pilot plant (under construction), and core storage locations.

WEIR concluded that Ramaco has facilities and equipment that are more than adequate to perform the tasks required for Ramaco’s exploration programs. At the time of the site visit, four drilling rigs were onsite with two operational drilling portions of the fence section in the central portion of the property.

Mr. Woloschuk first visited the Brook Mine on October 24, 2024 and has conducted approximately four visits through December 31, 2025. During these visits Mr. Woloschuk visited the Brook Mine test pit to observe exposures of the mineralized zones and the site topography.

​

**3.0** **Property Description**

**3.1** **Property Location**

The Brook Mine is located within Ramaco’s mineral holdings in Sheridan County, Wyoming, approximately seven miles north of the city of Sheridan. The BNSF Railroad and Interstate 90 are located along the southern boundary of the Brook Mine’s permit area.

The Brook Mine is situated in the Sheridan Coal Field in the northwestern portion of the PRB coal producing region of the United States (see Figure 1-1). The USGS 7.5-minute quadrangle map sheets are Acme, Hultz Draw, Monarch, and Sheridan, and the property lies within Townships 56 and 57 North, Ranges 84 and 85 West. The test pit within the Brook Mine is located near a latitude of 44 degrees 55 minutes North and longitude of 103 degrees and 3 minutes West.

**3.2** **Property Area**

The Brook Mine covers a portion of the approximately 15,800 acres of Ramaco owned and leased mineral holdings located in Sheridan County, Wyoming. Ramaco acquired the mineral holdings in 2011 from the SWCC, then a subsidiary of The Brinks Company.

When Ramaco began development of the Brook Mine as a thermal coal resource in 2012, Ramaco permitted approximately 4,500 acres that it regarded as the optimal area for a new surface coal mine. As Ramaco began further core drilling exploration in 2021 and 2022 relative to CMO exploration, Ramaco decided to continue to drill in areas within the original permit boundary and at comparable depths related to coal mining in order to leverage the existing drilling core available for sampling.

As a result of the drilling concentration within the existing mining permit boundary, the current Brook Mine Mineral Resource falls within the aerial extent of the current coal mining permit boundary. This Brook Mine surface area represents less than 30 percent of the total mineral acreage controlled by Ramaco in Sheridan County.

Ramaco owns 93 percent of the mineral rights and controls the remaining 7 percent associated with the Brook Mine Mineral Resource estimate described in this TRS. Ramaco also owns 40 percent of the surface rights associated with the Brook Mine Mineral Resource. The remaining

​

​ ​

July 24, 2026 Page 22

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

60 percent of surface rights are controlled through reserved surface access rights, surface access agreements, and leases.

No coal, mineral, or surface estate within the Brook Mine is federally owned or federally leased as of December 31, 2025. Accordingly, the federal regulatory framework that applies to leasable federal coal under the Mineral Leasing Act of 1920 (30 U.S.C. §181 et seq.; 43 CFR Group 3400) and to federal coal leasing decisions does not apply.

Ramaco’s owned facilities in the Sheridan, Wyoming area include its operations office, which also houses the Ramaco iCAM Center. The iCAM Center is an integrated carbon resource, research and development, and production facility. Ramaco also has numerous Conex trailers as well as rental storage units for storage of drill hole cores.

**3.3** **Surface Control**

Ramaco was granted a mineral deed from the SWCC on August 17, 2011. The SWCC had previously deeded the surface rights, as described in Table 3-1, to Big Horn Coal Company on June 28, 1954, and recorded in Deed Book 98, Page 127 in the Sheridan County Courthouse. The deed grants Ramaco all coal and other minerals contained in all of the lands included in the lease, together with the right to mine, explore, drill, extract, and remove the same. The deed also grants Ramaco the right to use surface lands, as needed, to mine, explore, drill, extract, and remove said coal and other minerals.

Further, the deed grants that should Ramaco mine, drill, explore, extract, process, and remove coal or other minerals and utilize any part of the surface lands in connection with those activities, Ramaco will remain free from any liability or claim for damage to the surface of said lands related to subsidence or other injury to the surface of said lands resulting from such operations, however, Ramaco will be responsible for complying with statutory obligations under the Wyoming Environmental Quality Act, the Wyoming Land Quality Division coal rules, the Surface Mining Control and Reclamation Act of 1977 (SMCRA) as implemented by Wyoming’s approved program, and Wyoming water-quality law.

Ramaco was granted a Surface Owner Consent and Surface Use Agreement from Padlock Ranch Company on September 1, 2016. The agreement provided Ramaco with surface owner consent to mining certain surface lands located in Sheridan County, Wyoming, which can be extended five years up to four times. There is an area within Sections 17 and 20 where Ramaco agreed not to surface mine. These surface mining exclusion areas are excluded from Mineral

**3.4** **Mineral Control**

Ramaco was granted a mineral deed from SWCC on August 17, 2011. The mineral deed granted Ramaco all of Grantor’s right, title and interest in the coal and other minerals, except the oil, gas and coalbed methane for the mineral. The mineral deed also reserved a nonparticipating coal royalty in the amount of $0.10 per clean coal ton payable to SWCC.

In addition to Ramaco’s surface use rights, Taylor granted Ramaco, by Warranty Deed from Taylor on September 17, 2025, the surface lands, coal and mineral rights, improvements, appurtenant water rights and related permits, and ditch rights controlled by Taylor. As part of the Taylor purchase, Ramaco assumed executive rights of the remaining mineral interest alongside the 50 percent interest purchased from Taylor.

In addition to the SWCC and Taylor agreements, Ramaco was granted a Coal Mining Lease Agreement, originally executed on November 16, 2012, by and between William J. Laya and Joyce J. Laya, Trustees of the William J. Laya Trust under Trust Agreement dated November 19, 1993, and Joyce J. Laya and William J. Laya, Trustees of the Joyce J. Laya Trust under Trust Agreement dated November 19, 1993 and Thomas C. Laya (collectively, Laya). The Laya Agreement granted Ramaco the exclusive right and privilege to mine, extract, and remove all of the coal deposits, and other minerals commingled therewith in and under the land for a period of 20 years, and from year to year thereafter until all mineable and merchantable coal has been exhausted. The Laya lease requires a minimum royalty of $5,000 per year, which is recoupable during the life of the lease. In addition, the Laya Lease requires a production royalty of 8.0 percent of gross value of all coal mined from the lease, FOB mine, by surface, underground, or highwall mining methods.

As the Laya lease does not expressly provide Ramaco the right to extract CMOs other than the minerals commingled with the coal, the TCM Mineral Resources estimated in this TRS exclude TCMs within this property.

The Laya lease provides Ramaco the right, during the life of the agreement, to remove coal from adjoining, adjacent or nearby lands in conjunction or connection with coal operations on the Lands and to haul and transport said coal and any other materials over, under, upon and through or across any part of the Lands in conjunction or connection with operations carried on or conducted by Ramaco.

**3.5** **Significant Property Encumbrances and Permit Status**

There are certain property encumbrances identified within the Brook Mine, which include the following:

- The Laya coal lease area is excluded from Mineral Resource estimation as the mineral lease does not explicitly provide for the mining of CMOs.
- A portion of the Padlock Surface Use Agreement is excluded from Mineral Resource estimation as it carries a restriction on surface mining rights.
- Other property encumbrances, with minimal impact on current Mineral Resource pit designs, exist relative to the following:

Ø Railroad Right of Ways (ROW) - BNSF (operating Grand Island & Northern Wyoming RR, Chicago, Burlington & Quincy, Burlington Northern lines) crosses Sec. 18, 21, 22, 27 of T57N-R84W; Grand Island & Northern Wyoming RR also holds an Oil, Gas, Coal, and Mineral reservation in W½ Sec. 22.

Ø Highway/road ROWs - Interstate 90 (WYDOT), County Road #1260 (Acme/Old US-87), Monarch/Hidden Water-Ash Creek Road, and Slater Creek County Road 95.

Ø Electric utility ROWs - Sheridan County Electric Co. c/o Montana-Dakota Utilities Co. (with a 0.2-acre substation parcel in NE¼NE¼ Sec. 21 excepted from the permit), Powder River Energy Corp., and Sheridan-Johnson REA.

Ø Telecom ROWs - Mountain States Telephone & Telegraph (CenturyLink/Lumen successor), defunct Sheridan-Montana Telephone Co., and a Verizon Wireless tower-site lease in NW¼SE¼ Sec. 13.

Ø Grazing leases - Padlock Ranch holds grazing leases over BLM lands (Sec. 5) and State Trust Lands (Sec. 10).

Ø Oil, Gas, Coal Bed Methane severances - Pine Mountain Oil & Gas (broad coverage); plus reservations in favor of the Lynch family heirs, Welch Foundation Trust, Lonabaugh/Kelloway/Powder River Oil & Gas Ventures II, the Hitson family, Ruth Schreibes, the Owen/ Carroll/Reed/ McPhillamey/ Dawdy group, and the Laya Family Trusts.

Ø Federal/State interests - BLM federal coal in Sec. 4 S½ and Sec. 5 S½SE¼; State of Wyoming surface and minerals in Sec. 10 (with Coal Lease to Black Gold Land Co. LLC).

Ø Surface use agreements/orders in lieu of consent - recorded with the Laya Trusts, Padlock Ranch, and Big Horn Coal. The order in lieu of consent granted Ramaco the

​

​ ​

July 24, 2026 Page 31

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

right to use the surface of Big Horn Coal for surface mining by the Wyoming Environmental Quality Council.

Ø Water rights - 67 listed records (WR-1 through WR-67). The 1891 Hanover Ditch and the C.B. & Q. Pipeline/Tongue River Ditch are senior surface rights crossing Sec. 19, T57N-R85W.

Ramaco was issued Permit No. 841-T1 on July 7, 2020, by the Land Quality Division of the Wyoming Department of Environmental Quality for surface mining of coal in Sheridan County, Wyoming. Permit No. 841-T1 consists of 4,541 acres. The permit boundary is shown on Figure 1-1. The Brook Mine has a Mine Safety and Health Administration (MSHA) ID# of 4801799. WPDES permit No. WYR001608 allows discharge of stormwater from the permit area.

Ramaco was issued Air Quality Permit P0025939 for the Brook Mine on July 20, 2020 by the Air Quality Division of the Wyoming Department of Environmental Quality, as described in Wyoming Permit No. 841-T1.

All permits for development of the Brook Mine are active and up to date in order to mine coal. However, to allow mining deeper seams, as well as to specifically allow the extraction of CMOs, Ramaco will be required to revise its mine plan, which will require a revision to the Mining and Reclamation Plan in Permit No. 841-T1.

Additionally, Ramaco will require permitting approvals for its CMO processing and tailings facilities, once design of those have been completed.

**3.6** **Significant Property Factors and Risks**

WEIR assesses that there are certain property risks that could affect Ramaco’s ability to execute its mine plans. Property risks which Ramaco will need to address include the following:

- Current mining permit approves surface mining of only coal and does not specifically identify CMO mining rights. Coverage of CMO mining under existing mineral conveyances may require an amendment to the existing mining permit.
- Revising the Brook Mine Permit to include CMO processing and tailings facilities will require detailed engineering design and environmental study, including an updated reclamation plan, additional self-bonding or surety bond sized to cover full reclamation, long-term tailings closure, and water treatment, if needed. A WYPDES permit is

​

​ ​

July 24, 2026 Page 32

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

required for any point-source discharge from the process plant, tailings underdrains, stormwater contact areas, or pit dewatering. A construction permit is needed before building the process plant to cover emission sources. An Industrial Siting Permit from the Wyoming Industrial Siting Council may also be required.

- Pine Mountain Oil and Gas, Inc. holds oil, gas, and coalbed methane rights across the property. Currently, there are no producing wells, plugged wells, Coalbed Methane (CBM) wells, gathering lines, compressor stations, injection wells, or future well commitments on the Brook Mine site. To date, no oil and gas company has commenced operations within the Brook Mine site, nor have any filings for development occurred with the Wyoming Oil & Gas Commission. Areas adjacent to the Brook Mine had experienced historical CBM development, but none are active at present. Additionally, all gathering lines and infrastructure have been removed in the adjacent areas, and wells, if not plugged, have been released to landowners. Should Pine Mountain, or any other oil and gas company, pursue development of their oil, gas, or coalbed methane rights, Ramaco could accommodate those rights by mining around any active facility, relocating wells, or reaching an agreement with the company. Currently, the potential development of oil, gas, or CBM is unlikely.

WEIR did not conduct an independent verification of property control, nor has it independently surveyed the mining locations. WEIR has relied on information compiled from documents, maps, and summaries of the owned and leased properties prepared by Ramaco. WEIR did not conduct a legal title investigation relative to Ramaco’s mineral and surface rights.

**3.7** **Royalty Interest**

Ramaco, at the Brook Mine, holds no royalty or similar interest in property that is owned or operated by another party.

Further, Ramaco intends to purchase the remaining minor mineral ownership interest not currently owned by Ramaco. As a result, no private interest mineral royalties are anticipated for the extraction of TCMs. The non-participating coal royalty owned by SWCC has been included in the operating cost estimates. Ramaco has assessed various federal, state, and local royalties and/or taxes that will be applicable and which are considered in the Brook Mine economic analysis. These taxes are described further in Section 18.2.

**4.0** **Accessibility, Climate, Local Resources, Infrastructure, and Physiography**

**4.1** **Topography, Elevation, and Vegetation**

The Brook Mine is located on the western edge of a broad plain that extends from the Bighorn Mountains to the Black Hills of South Dakota. This area is characterized by high plateaus, which have been dissected by meandering streams, leaving ridges between the main watersheds. Surface elevations range from a low of 3,600 feet above mean sea level (MSL) on the eastern edge of the property to a high of 4,080 feet above MSL in the northwest area of the property. The main drainages in the area are the eastward flowing Tongue River, and Goose Creek, flowing to the north. The confluence of these drainages is near the old town of Acme, Wyoming.

The landscape is dominated by grasslands and sagebrush communities, with Upland Grassland, Big Sagebrush Shrubland, Scoria Grassland, Reclaimed Grassland on previously mined ground, Rough Breaks Mixed Shrubland, and Prairie Dog Modified Grassland accounting for most of the Brook Mine Permit Area. Smaller components include Pine and Juniper Woodland, Riparian Woodland along the Tongue River and Slater Creek, Bottomland Sagebrush Grassland, Rabbitbrush Shrubland, Agricultural Land, and minor disturbance and water features. Native cool-season perennial grasses, chiefly western wheatgrass and bluebunch wheatgrass, dominate herbaceous cover, with Wyoming big sagebrush the principal shrub on uplands and common snowberry, eastern cottonwood, green ash, and peachleaf willow defining the riparian corridors. Cheatgrass, an introduced annual, is prominent on Scoria and Upland Grassland sites, while smooth brome and crested wheatgrass dominate Reclaimed Grassland and bottomland areas. No prime cropland or pastureland of statewide importance occurs within the permit area, and no federally listed threatened or endangered plant species were documented during the surveys.

**4.2** **Property Access**

Access to the property is from Interstate Highway 90, which crosses the property from west to south. State Highway 338, which connects Sheridan to Decker, Montana, crosses the southeastern portion of the Brook Mine’s permit area. Secondary roads and trails provide access to the remaining lands. Rail access is by the BNSF Railroad, which is located in the Tongue River and Goose Creek valleys.

​

The nearest airport is the Sheridan County Airport (SHR), which is located in Sheridan, Wyoming, approximately seven miles southeast of the Brook Mine. The Billings Logan International Airport (BIL) in Billings, Montana, is located approximately 95 miles northwest of the Brook Mine.

The waterways surrounding the property are not navigable for commercial traffic.

**4.3** **Climate and Operating Season**

The Brook Mine has a semi-arid climate with four distinct seasons. The summers are warm and dry, with temperatures ranging from the mid-80’s to low 90 degrees Fahrenheit (28-33 Celsius) in July and August. The winters are cold and snowy, with temperatures averaging 20-30 degrees Fahrenheit (-7 to -1 Celsius) in December and January. Spring and fall are transitional seasons, with cooler temperatures and occasional rain and snow.

Coal mining operations in the region operate year-round, regardless of weather conditions.

**4.4** **Infrastructure**

**4.4.1** **Water Supply**

Water used in the Brook Mine facilities will include potable water and industrial water. Potable water at surface facilities is and will be provided from on-site wells.

Industrial water will be used for dust suppression on the haul roads, equipment wash down, and process plant. This water will be obtained from on-site wells, collection basins constructed on site and other nearby sources, including old underground mine workings.

**4.4.2****Electrical Power**

Ramaco currently purchases electricity from MDU for its surface facilities. Services from MDU are currently being upgraded for electrical supply to pilot processing facilities. This will require further expansion for commercial operations. The basis for power consumption and cost is discussed in Sections 14 and 15.

​

**4.4.3** **Personnel**

Acquiring suitable personnel to operate the mine and process plant may prove to be a challenge for Ramaco. The Brook Mine is close to Sheridan, Wyoming, and as of 2025, its population is approximately 20,000. There are also other smaller towns surrounding the Brook Mine. As such, the availability of experienced new hires may be limited. Some experienced personnel may be available from Gillette, Wyoming (110 miles southeast) which, over the last few years, has experienced a reduction in mining personnel. Ramaco may also need to recruit from towns further away from the Brook Mine. However, WEIR believes that with concentrated recruitment efforts, Ramaco will be able to fully staff the Brook Mine as planned.

**4.4.4** **Procurement**

There are many mining supply and heavy equipment vendors in the surrounding area. Ramaco currently uses local vendors in Sheridan, Wyoming (seven miles to the south) for most of its current heavy equipment needs. Gillette, Wyoming is 110 miles to the southeast and has many mining supply and heavy equipment vendors that can serve as an alternative source of equipment and maintenance needs. Casper, Wyoming is 160 miles to the south and is home to several heavy equipment and mine supply vendors as well.

**5.0** **History**

**5.1** **Previous Operations**

Much of the history of coal mining in the Sheridan Coal Field was provided in a John T. Boyd Company report, *Potentially Strip Mineable Coal Reserves Contained on the Sheridan-Wyoming Coal Company Property*, dated November 20, 1979 (Boyd Report).

The Boyd Report indicated that underground coal mining began in the Sheridan coal field around 1894 and lasted until 1953. During this period, there were 14 deep mines in the vicinity of the Brook Mine. The coal was used domestically in the Sheridan area, and to supply the railroad. Most of the mines were individually owned until 1920 when the major mines, the Dietz, Acme, Model, Carney, Monarch and Kooi, were consolidated and incorporated under the Sheridan-Wyoming Coal Company, a subsidiary of United States Distributing Corporation. This corporation and the subsidiary, Sheridan-Wyoming Coal Company, merged with The Pittston Company in 1943.

Information on these mines is very sparce and consists of mine maps for six of the mines, with boundaries available for all of the mines. In March 1978, John T. Boyd Company engineers visited the Wyoming Inspector of Mines in Rock Springs and reviewed mine maps of the Monarch Mine 45, Monarch Mine 45-2, Acme Mine 42, Hotchkiss, Model, and Armstrong mines.

Bottom of seam elevations were shown for all the mines except Model and Armstrong; seam heights were available only for the Acme Mine 42. Available data indicates that the bottom 14 feet of the Monarch Seam was mined in the Monarch Mine 45-2. The maps also indicate that pillars were pulled during retreat mining; i.e., the majority of pillars in Monarch Mine 45 and Acme Mine 42, and 20 percent in Monarch Mine 45-2. Excessive subsidence of surface above the Acme Mine 42 and Dietz No. 1 and 2 mines can be seen in aerial photographs.

In 1943, Peter Kiewit Sons’ Company formed a coal mining subsidiary, the Big Horn Coal Company (Big Horn). Operations commenced on a Wyoming state lease in Section 36 (T. 58N., R. 85W.), located approximately three miles north of the northwest corner of the Brook Mine. In 1954, Big Horn entered into a coal lease agreement with the SWCC and operations commenced in Section 22 (T. 57N., R. 84W.). From 1954 through 1969, coal production averaged about 350,000 tons per year. In 1970, coal production increased to approximately one

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

million tons per year due to increased demand for western coal. Big Horn abandoned its mining operations in year 2000.

No CMO mining has occurred historically in or around the Brook Mine.

**5.2** **Previous Exploration and Development**

Exploration of the Brook Mine, prior to Ramaco’s ownership, was limited to coal exploration drilling. Bighorn Coal, over the timespan of its operation of the property, drilled 417 coal exploration drill holes prior to 2011 that Ramaco incorporated into their drill hole database as a result of information transfer.

**6.0** **Geological Setting, Mineralization, and Deposit**

**6.1** **Regional, Local, and Property Geology**

**6.1.1** **Regional Geology**

The Sheridan Coal Field is located within the northwestern portion of the PRB. The regional geology of this area is characterized by a sequence of sedimentary rocks that formed during the Late Cretaceous to early Paleocene Periods. The stratigraphic sequence consists of interbedded sandstones, mudstones, and coal seams that were deposited in fluvial, deltaic, and lacustrine environments.

The Sheridan Coal Field is situated within the Tongue River Member of the Fort Union Formation. This formation is composed of interbedded sandstones, shales, and coals that were deposited during the Paleocene Period. The thickness of the Tongue River Member varies from 150 to 400 feet and contains several coal seams that range in thickness from 1 to 30 feet. These seams exist down to depths of approximately 1,200 feet across the property.

The coal seams in the Sheridan Coal Field are classified as low-sulfur, sub-bituminous coal. These coals have a low ash content, high calorific value, and low sulfur content, making the coal ideal fuel for power generation. The coal seams are generally continuous over large areas and are flat-lying, and amenable to surface mining.

The sedimentary rocks in the Sheridan Coal Field were deposited in a series of ancient rivers and lakes that once covered the area. These rivers and lakes were fed by the highlands to the west and north, and the sediment was deposited as the water slowed and lost its carrying capacity. The sandstones were deposited in the channels of the rivers, while the shales and mudstones were deposited in the floodplains and lakes.

The regional geology of the Sheridan Coal Field has been influenced by tectonic activity in the region. The area has experienced several episodes of uplift and subsidence, which have created a series of fault blocks and basins. The coal seams in the Sheridan Coal Field are located in these basins, which has preserved the coal seams from erosion.

​

**6.1.2** **Local Geology**

The Brook Mine is located on the western edge of a broad plain that extends from the Bighorn Mountains to the Black Hills of South Dakota. This area is characterized by high plateaus, which have been dissected by meandering streams, leaving ridges between the main watersheds. Surface elevations range from a low of 3,600 feet above MSL on the eastern edge of the property to a high of 4,080 feet above MSL in the northwest area of the property. The main drainages in the area are the eastward flowing Tongue River, and the northward flowing Goose Creek. The confluence of these drainages is near the old town of Acme, Wyoming.

Structurally, the coal seams dip to the southeast between one to four degrees. Locally the dip may reverse due to differential compaction. Fault traces over the Brook Mine have been presented in past studies, however, there has been insufficient data collected to accurately estimate dip and throw of the faults. In reviewing the structural model based on the available data, there are no apparent discontinuities present with faulting most likely producing localized displacement. Additional exploration and mapping should be conducted to confirm the location and extent of these previously presented fault traces.

Interpretation of local faults using existing geophysical drill hole data is currently being performed to improve the structural accuracy of the geological model for future mine planning purposes and is anticipated to improve understanding of mineral continuity within the Brook Mine.

**6.1.3** **Property Geology**

The primary coal seams associated with CMOs on the Brook Mine, in descending stratigraphic order, are the Dietz 1, Dietz 2, Dietz 3, Monarch, Upper Carney, Lower Carney, and Masters. There are also seven unnamed seams below the Masters Seam that have been included in the models. There are several other coal seams found below this to depths of approximately 1,200 feet, based on data available from historical oil well logs. Most of these seams are thin (1-2 feet) and unnamed. However, within this lower group, the Upper Pawnee, Lower Pawnee, and Wall seams may be found.

​

**6.2** **Mineral Deposit Type**

**6.2.1** **TCM Resources**

The TCMs are believed to have been incorporated into the coal during its formation and are found in association with clay minerals and organic matter in the coal seams. Interburden between the coal seams also contain elevated levels of TCMs, primarily in clays, carbonaceous clays, and siltstones not necessarily associated with the coal seams. It is assumed that the TCMs are hosted within the clays, carbonaceous clays and siltstones through ion adsorption.

Various coals within the Brook Mine have TCM concentrations far surpassing those observed in coals worldwide. It is hypothesized that the concentrated TCMs within the coals may be attributed to the infiltration of fluids through permeable and porous coal zones (via cleat fracturing) and other carrier beds, such as sandstones. These fractured zones have been identified in core, but not mapped and correlated to the highest concentration zones. The fluid flow is believed to have induced an acidic environment within the coals, due to the inherent organic concentrations, while transporting dissolved metals in solution. This is evidenced by the identification of gypsum within the mineralized coal zones. The TCM metals could have precipitated and accumulated within oxide minerals at coal/clay boundaries, where varying redox conditions and pH differences facilitated the TCMs’ aggregation and concentration. The thickness of these mineralized zones can reach up to eight feet in the cores analyzed. Additionally, there is an inherent reducing and acidic environment associated with the coals during deposition. There is likely significant dissolution of detrital minerals and reprecipitation within the carbonaceous shales and claystones during early diagenesis.

An important component of this hypothesis is establishing whether the mineralization is primary or secondary. It could be possible that the source of the TCMs is by primary deposition via airborne particles of volcanic origin, proximal to this particular peat system, and incorporated into the coals during deposition. The substantial volume of coal, reaching a thickness of 30-feet in some zones, certainly implies a dominant airborne input, although no evidence to date has been found of existing ash layers. A comprehensive understanding of the cleat systems is imperative to substantiate the viability of fluid flow through coals as carrier beds.

Based on this depositional theory of TCM enriched fluids flowing through the coal strata and depositing concentrated TCM mineralization into the clays and siltstones immediately surrounding the coal seams, it is inferred that geologic and grade continuity is present for the

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

TCM mineralization in connection with the continuity of the coal seams throughout the Brook Mine. Exploration and sampling have confirmed elevated TCM concentrations within approximately five feet above and below the coal seams. Elevated TCM concentrations have also been sampled at distances greater than five feet from a coal seam, however these occurrences have been sporadic and unable to be correlated across large areas unlike the mineralization immediately adjacent to the coal seams.

**6.2.2** **Coal Resources**

The regional geology of this area is characterized by a sequence of sedimentary rocks that formed during the Late Cretaceous to early Paleocene Periods. The stratigraphic sequence consists of interbedded sandstones, mudstones, and coal seams that were deposited in fluvial, deltaic, and lacustrine environments.

For internal purposes, Ramaco produces geologic resource models using the Carlson® mine planning software package. WEIR has modeled the resources using Datamine MineScape® Stratmodel (MineScape) geological modeling software.

**6.3** **Geological Modeling**

Ramaco provided WEIR drill hole data, which included survey, lithology, and TCM and coal quality information. This data was provided in different formats including Excel, ASCII files and PDFs. Geophysical logs, coal quality certificates, driller’s logs, geologist’s logs, and drill hole survey records were provided as scanned PDF files and AutoCAD drawing files. Of the 770 drill holes provided to WEIR by Ramaco, 155 were rejected primarily due to missing coordinates or lack of acceptable lithology data.

Coal quality data for 92 drill holes was provided by Ramaco, all of which WEIR considered suitable, and were used in WEIR’s geological model. ICP-MS data was provided for 128 drill holes which involved 5,903 analyses. Similarly to coal quality drill holes, none of these TCM quality drill holes were rejected by WEIR. The data provided by Ramaco was in Excel and ASCII format along with quality certificates in PDF format.

Two geological models were constructed using Datamine’s MineScape® software. This involved a primary stratigraphical model and a resultant block model. The primary stratigraphical model delineates coal seams and interburdens as zone input for the block model.

​

​ ​

July 24, 2026 Page 42

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

This stratigraphical model was directly used for coal tonnage and quality estimates. The block model was specifically created for TCM tonnage estimates.

**6.3.1** **Stratigraphic Model**

The MineScape® stratigraphic model was created based on ArcGIS® World3D topography. In the United States, this incorporates topography from the USGS 3-D elevation project. Topography data was gridded using MineScape® software and a grid cell size of 50 feet by 50 feet from the USGS on-line 3-D Elevation Project data source. The resolution of the topography data is 1/3 arc-second, which results in approximately 30 feet by 30 feet data point spacing. The gridded USGS topography contours were compared to drill hole collars. WEIR investigated and resolved significant collar elevation discrepancies.

The seam surfaces and thicknesses were created by loading the drilling and mine measurement data into MineScape® and gridding the seam intercepts using a grid cell size of 50 feet by 50 feet. The parameters used to create the model are defined in the MineScape® modeling schema, which is a specification of modeling rules created for the site. The MineScape® interpolators that were used in this study are common in most mine planning software. The Planar interpolator is a triangulation method with extrapolation enabled. The Height interpolator is a variant on the trend surface and inverse distance interpolators. The data points are weighted, thus producing a different plane at each sample point. By using a weighting curve that is infinite at zero distance, data honoring can be assured. Due to the least squares fit, the effect of data clustering is minimized. A trend surface is used in MineScape® to promote conformability for the modeled seams to regional structures, such as synclines, anticlines, or simply seam dip. MineScape® caters to using different interpolators for thickness, roof and floor surfaces, and the selected trend surface as all are modeled separately. The interpolator used for each of these items is selected on the basis of appropriateness to the data sets involved, as well as modeling experience. Stratigraphic Model Interpolators are shown in Table 6-1, as follows:

**Table 6-1****Stratigraphic Model Interpolators**

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**6.3.2** **Block Model**

A MineScape® block model was constructed using a cell size of 50 feet by 50 feet by 0.5 feet (i, j, k vectors) using the zones defined by the coal seams as modeled in the stratigraphic model described above. The vertical k-component of the block model (0.5 feet) was selected to closely reflect the average pXRF and ICP-MS sample intervals of 0.25 feet. An inverse distance interpolator with the power of 2 was used to interpolate TCM grades into the block model. A search radius of 2,800 feet was utilized based on twice the average drill hole sample spacing to ensure sufficient samples were utilized to inform each block within the model. Insufficient sampling has been conducted to complete a comprehensive geostatistical analysis at this time. Ramaco is in the process of drilling and sampling three sets of perpendicular geostatistical fence sections with drill holes spaced between 100 and 200 feet apart in order to collect sufficient data to inform a comprehensive geostatistical and drill hole spacing analysis.

**6.3.3** **Coal Quality Model**

To create the coal quality model, coal quality data from previous exploration and from Ramaco coal exploration drilling was used. The drill holes were verified to ensure that the seam depths used in the lithology file matched the sample depths in the quality file. Coal quality samples were loaded into MineScape® and composited against the drill hole thicknesses. The composited values were then gridded using a grid cell size of 200 feet by 200 feet and the inverse distance weighted (squared) interpolator. In addition to raw density and total moisture, the following quality data was modeled for all seams for which quality data was available:

- Ash (weight percent), on a dry basis and As-Received (AR)
- Calorific Content (Btu/lb), on a dry basis and AR
- Total Sulfur (weight percent), on a dry basis and AR
- Volatile Matter (weight percent), on a dry basis and AR

**6.4** **Stratigraphic Column and Cross Sections**

Figure 6-1 shows the stratigraphic column for the Brook Mine. Typical stratigraphy of the Brook Mine can be seen on Figure 6-2. Typical block model cross sections with estimated TCM concentrations displayed can be found on Figure 6-3.

**7.0** **Exploration**

**7.1** **Non-Drilling Exploration**

Drilling has served as Ramaco’s primary form of exploration within the Brook Mine. However, nine bulk samples were obtained through under-reaming from nine drill holes across two locations (see Figure 7-1). An average of approximately 500-pound samples were obtained from each of the nine drill holes. The samples were bagged in approximately three feet intervals, photographed, labeled, and shipped to the lab for analyses.

Additional channel and bulk samples were collected in the second half of 2025 as Ramaco began development of a test mining pit targeting the Dietz and Carney seams in the south-central portion of the Brook Mine. A total of 185 channel samples were taken from nine locations across the test pit covering an area 150 feet wide by 200 feet long. Channel samples were collected vertically as the pit was developed to collect samples through the Dietz and Monarch coal and interburden zones on approximately one foot intervals. Overall thicknesses sampled by the channel samples ranged from eight feet to 48 feet and averaged 28 feet. Channel samples were taken by hand utilizing hand tools to break out a predetermined width and depth of material from the sample location. Material removed was collected on a tarp setup to capture as much of the material removed as possible, however some sample loss as well as dilution was observed.

Material was excavated by scrapers from the pit area and stockpiled by horizon before being systematically sampled with a backhoe to collect 162 bulk samples (approximately one ton each) from three horizons (Dietz 3 Seam mixed coal and interburden, Monarch Seam interburden, and Upper Carney interburden). Samples were predominantly collected from the Monarch and Dietz 3 Seam interburdens with only 18 samples collected from the Upper Carney interburden. Bulk samples represent up to 20 feet vertically of material.

Analysis of these samples was conducted and received in 2026 following the effective date of this report and as such are not incorporated into any of the modeling presented in this TRS. WEIR has prepared a summary of the channel and bulk samples compared to adjacent core hole drilling to demonstrate grade continuity over larger areas and sample quantities. A comparison of average drill hole TCM grades, channel sample TCM grades and bulk sample TCM grades by available mineralization zone is presented in Table 7-1.

​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 7-1****Average TCM Metal Grade Comparison by Sampling Type**

As shown in Table 7-1, there is some variability between the three sample types but generally the channel and bulk samples show higher concentrations of TCMs supporting the continuity of grade across larger areas. WEIR believes this data supports grade continuity across larger areas and the ability to extract TCMs from the Brook Mine with minimal dilution.

**7.2** **Drilling**

**7.2.1** **General Methodology**

Ramaco’s exploration activities for CMOs at its Brook Mine primarily involve drilling. Drilling that targets CMOs has generally been on a 1,000 feet north/south grid. CMO exploration drill holes are cored from surface to full depth to ensure all potential mineralization is captured for sampling. A 2.5-inch diameter core is extracted in roughly 10 to 20 foot core runs.

​

​ ​

July 24, 2026 Page 49

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The first Ramaco coal exploration drilling program carried out at the Brook Mine, prior to the 2019 CMO interest, involved drilling a rotary pilot hole to establish coal seam depths. The pilot hole information was used to drill a near-duplicate drill hole which alternated between rotary and core drilling where cores were obtained for the coal seams and coal roof and floors.

During core drilling, a split-tube core barrel of up to approximately 20 feet length is retrieved from depth and then opened. The core is washed down if necessary, and the driller’s reported length of core that was actually cut is compared to the measured length of core actually recovered. If a section of core greater than 10 feet, or less if in a critical zone, is lost, the hole is re-drilled to obtain data for the lost interval. All core samples are boxed, labeled, photographed, and stored in an on-site enclosed building.

A hole with significant lost core or crushed core can result in misleading data. Drill holes with core recovery of less than 90 percent of targeted interests are noted and subsequently reviewed and potentially excluded from geological and coal quality modeling. WEIR did not exclude any drill holes for poor core recovery, since all of the holes provided to WEIR within the Brook Mine attained core recovery of at least 90 percent.

For the original CMO exploration drill holes, pXRF analysis was performed on 3-inch to 12-inch increments for the cores, depending on mineral concentrations being found at those locations. Based on the pXRF analysis, sections of core were selected for ICP-MS analysis. Core samples were then sent to laboratories for ICP-MS analyses. As of January 2024, new procedures were put in place where the core was sampled on even increments, 3-inch or 6-inch, independent of pXRF analysis. All new core drilled as of January 2025 were halved and sampled on 6-inch composites and sent for ICP-MS analysis. In late 2025 the sampling regiment was changed to 1-foot composites taken within the current sampling zone consisting of five feet above and below the coal seam as well as two feet of coal from both the roof and floor of the seam.

For coal exploration drill holes, cores are taken of the seam in approximately 2-foot intervals. Core splits are bagged, labeled, and sent to laboratories for proximate analyses on both a dry and as-received basis.

Select holes are geophysically logged with a standard coal suite tool consisting of gamma, density, caliper, and resistivity. Geophysical logging contractors provide paper copies, .TIF files, .DWG files, and .LAS files. After the 2022-2023 100-hole drilling program, all newer

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

holes have been geophysically logged as a result of revised best practice standard operating procedures.

All original drill hole, survey, geological, geophysical, and quality data is scanned and stored on a Ramaco server, which can be accessed by select Ramaco personnel and quickly checked against the database, the geological model, or mine mappings. Each drill hole collar location is surveyed using RTK GPS for accurate map coordinate and elevation data.

Table 7-2 summarizes Ramaco’s drilling programs that have been completed at the Brook Mine. In addition to Ramaco’s drilling programs, historical coal drilling data obtained from Bighorn Coal is also shown. Ramaco has relied upon portions of the historical drilling data where it has been validated by Ramaco.

**Table 7-2****Brook Mine Drilling Programs**

**7.2.2** **Drilling Program Summaries**

From 2012 through 2018, Ramaco drilled 59 coal exploration drill holes to in-fill the Bighorn Coal data after acquiring the property. The assaying of drilled core was targeted at testing thermal coal quality, including moisture, ash, sulfur, and calorific value. No sampling was conducted at the time relative to CMO concentrations for any of these coal exploration drill holes. WEIR has reviewed these historical drill holes and confirmed the coal seam data was representative with drilling conducted by Ramaco.

Starting in 2019, interest in REEs was initiated on the property by NETL as part of its study of REEs within the PRB. Specifically, a 2019 6-corehole program was later expanded by an additional 14-corehole REE-targeted cored drill hole program during 2021-2022. These two initial REE-targeted programs sparked further interest in potential REE resources for the property.

​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

In 2019, Ramaco provided drill cores from the Brook Mine for a battery of qualitative and quantitative analyses conducted by the NETL. Analysis conducted by NETL included the following:

- High resolution photographic analysis
- Analysis of stratigraphic logs from existing coring
- Lithologic description and analysis
- Elemental analyses, including:

Ø REE, trace and major element analysis

Ø Thermogravimetric analysis

Ø Bulk X-Ray Diffraction/X-Ray Fluorescence analysis

Ø Inductively Coupled Plasma Mass Spectrometry

- Microscopy and Microanalysis by:

Ø Imaging (small and large area)

Ø Elemental analysis

Ø Phase Identification

As a result of the preliminary analysis conducted in conjunction with the NETL, between November 2021 and February 2022, Ramaco completed a comprehensive exploration drilling and coring program consisting of 14 new drill holes that resulted in 1,937 linear feet of 2.5-inch core drilling. This exploration program targeted the Monarch, Upper Carney, and Masters coal seams across the Brook Mine, and marked the first time the Masters Seam had been sampled and analyzed for REEs within the Brook Mine.

In April 2022, Ramaco initiated an additional 100-hole exploration program at the Brook Mine. This continued exploration was designed to establish an approximate 1,000 feet sampling grid for the Dietz, Monarch, Carney, and Masters coal seams within the Resource Area. Planned analysis of the new drill core data included pXRF analysis, as well as targeted secondary ICP-MS sampling and analyses on historical cores. This 100-hole drilling program was completed in July 2023 with seven additional holes drilled and sampled in 2024. The targeted secondary ICP-MS sampling and analysis program was completed in January 2024.

In late 2023, Ramaco conducted a deep hole drilling program. The program was designed to assess if REE grade could increase at depths beyond the approximate 200-foot average hole depths that had previously been completed. The deep core hole program involved three drill holes at planned depths of approximately 850 feet. Two of these holes were successfully completed to planned depths, while the other was not. These deep core holes were analyzed

​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

using ICP-MS along their full length. Geophysical logging was performed on all three drill holes as well. Results from the deep core hole drilling program did not reveal any substantially higher grade TCM zones at depth. The levels of critical minerals below the Lower 7 Seam were generally lower than those above the Lower 7 Seam, on average.

After completing the deep core and 100-hole programs, Ramaco drilled an additional nine holes for bulk sampling purposes. In order to collect the large bulk samples, Ramaco utilized underreaming of the holes to collect approximately 500-pound samples within the target zones. These holes were analyzed using ICP-MS and were geophysically logged. The bulk samples were intended to assist in analyzing mineral extraction and recovery options, but it was found the underreaming introduced significant dilution and the samples are not representative of the targeted horizons. The bulk sampling program was performed during the 2024 calendar year.

In addition to the deep core and bulk sampling programs, cores from the 100-hole program were extensively sampled and analyzed using both pXRF and ICP-MS to in-fill previously unsampled areas within the geological model. This sampling/analysis program continued through most of 2024.

The location of all exploration drill holes at the Brook Mine is provided on Figure 7-1. All 615 drill holes on Figure 7-1 were used to develop a comprehensive geologic structural model. This geologic structural model was in turn used to define the TCMs using the 5,903 ICP-MS samples assayed from 128 drill holes.

**7.2.3** **Planned Drilling**

Infill drilling will continue to be conducted to validate continuity and delineate the higher grade TCM zones that are beginning to emerge based on elemental testing and geologic mapping. There is also planned drilling for outside the permit boundary to begin extending known mineralization trends.

A drilling program in 2025 and 2026 is ongoing with three sets of perpendicular fence drilling programs planned and numerous groundwater monitoring wells to be installed to the Wall Seam.

**7.3** **Hydrogeological Data**

**7.3.1** **Surface Water**

For drainage structure design parameters, Ramaco used data from several sources in combination:

- Topography generated from LiDAR data collected by FugroEarthData, Inc. on October 16, 2013. The LiDAR data accuracy meets the National Map Accuracy Standards (United States Bureau of the Budget, 1947) for 1”=100’ scale, 2 foot contour interval mapping.
- To estimate runoff curves, data was used from the soils study that was prepared by James Nyenhuis, Certified Professional Soil Scientist, of Fort Collins, Colorado July 2015. Soils mapping, soil profile and map unit description, taxonomic classification, and soil sampling was conducted in accordance with the procedures and standards of the National Cooperative Soil Survey (Soil Survey Staff, 1993, 1997, 1998, 1999, and 2010; and Schoeneberger et al., 2012), and “Guideline No. 1, Soils and Overburden” (WDEQ-LQD,1996).
- Also to estimate runoff curves, data was used from the vegetation assessment of RAMACO’s Brook Mine that was conducted by BKS Environmental Associates, Inc. (BKS) of Gillette, Wyoming in 2013. All sampling procedures were designed according to the Wyoming Department of Environmental Quality, Land Quality Division (WDEQ/LQD) Rules and Regulations for Coal Permitting, Chapter 2 (WDEQ/LQD, 2012), and multiple consultations with the WDEQ/LQD. Baseline vegetation assessment sampling methodology derived by BKS was approved by WDEQ/LQD prior

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

to fieldwork. All sampling procedures outlined in the approved WDEQ/LQD baseline vegetation sampling methodology were executed as approved.

- For both the regional and site climate analysis, meteorological data were compiled for five sites surrounding the Brook Mine. These sites are all within a 15-mile radius of the mine permit area. Data was acquired through the Western Regional Climate Center (WRCC), the National Climatic Data Center administered by the National Oceanic and Atmospheric Administration (NOAA), Inter-Mountain Labs (IML Air Science, 2015) and the Wyoming Climate Atlas (Curtis & Grimes, 2004). Due to the proximity of the project area to the regional meteorological station locations, and since the climatology within the project area is similar to these stations, baseline climatology data at the project site was not collected. Since this time, a meteorological station has been established at the iCAM which will be incorporated into the site’s climatology database.

Once established, Ramaco input this data into the HEC-HMS (United States Army Corps of Engineers, 2009) for analysis. HEC-HMS uses a triangular Hydrograph Method, parametric method of estimating flood peaks and runoff volumes from site-specific data, in addition to providing watershed routing parameters. The Hydrograph Method is an industry standard for this type of work.

The planned Brook Mine established four surface water monitoring stations in September 2013, two sites on Slater Creek and two sites on Hidden Water Creek. Ramaco also uses data from five USGS gaging stations outside of the permit area. The data collected by the gaging stations is useful for observing and verifying water quantity trends in addition to monitoring surface water quality.

**7.3.2** **Ground Water**

Construction of the baseline groundwater monitoring network began in the third quarter of 2013 and was completed early in the fourth quarter 2013. The groundwater monitoring network consists of nine Carney Seam wells, 10 Masters Seam wells, eight alluvium wells, one underburden well, and one well perforated in both the Masters and Carney coal seams. No monitoring wells were completed in the overburden or interburden as no water was found in these units during drilling operations. The Groundwater monitor wells/piezometers were completed using air rotary methods in accordance with WDEQ/LQD guidelines.

Saturated hydraulic conductivity of the Carney and Masters coal confining intervals was measured on undisturbed core (boreholes 578513-5, R13-019, R13-023) using flexible-wall

​

​

constant-head permeameter testing per ASTM D 5084 (Method C), the standard test for fine-grained clays, claystones, and clayey sandstones. Formation-scale properties were obtained from constant-rate multi-well pumping tests (Section 9 cluster) and single-well slug tests, both accepted methods.

Each ASTM D 5084 test recorded sample geometry, dry density, moisture, saturation, gradient, and temperature, with a minimum of four to five sequential constant-head readings averaged at 20 deg C, and reports were independently reviewed. Field sampling required wellhead inspection, three-casing-volume purging (low-flow methods for wells under 0.5 gpm), pH/EC/temperature/DO/turbidity stabilization within 10 percent, ice preservation, chain-of-custody, and laboratory delivery within two days. Data validation included field-versus-lab EC and turbidity comparison, measured-versus-calculated TDS, ion balance, and holding-time checks. Pumping-test data were independently fit using Theis, Theis Recovery, and Cooper-Jacob solutions, and the regional aquifer-test population was screened to remove a small number of anomalously high values (interpreted as fractured-coal outliers).

Core permeabilities of the Carney and Masters confining clays and claystones averaged between 1.4E-6 and 2.0E-4 ft/day (one Masters lower-confining sandstone at 0.252 ft/day). Pumping-test results yielded T = 2.9 to 3.6 ft2/day and K = 0.48 to 0.60 ft/day for the Masters coal, and T = 5.6 to 6.0 ft2/day with K = 0.31 to 0.33 ft/day for the Carney coal, with storativities of 2.0E-4 to 3.8E-4 indicating a confined response. Material assumptions include the following:

- Permeable zones / aquifers: Carney coal, Masters coal, Tongue River alluvium, Slater Creek alluvium, and Big Horn Coal spoils. Overburden, interburden, and underburden are predominantly dry and treated as non-aquifers; the intervening claystones are confining units.
- Flow rates: regional flow is northwest to southeast down geologic dip, with local north-south offsets at faults. Hydraulic gradients are 0.008 to 0.016 ft/ft (Masters) and 0.017 to 0.07 ft/ft (Carney). Using K of 1.4 ft/day (Masters) and 0.097 ft/day (Carney) and a porosity of 0.10, seepage velocities are 40 to 80 ft/yr (Masters) and 6 to 25 ft/yr (Carney); Darcy fluxes are 4 to 8 ft/yr and 0.6 to 2.5 ft/yr, respectively. Vertical migration through confining units is estimated at less than 0.5 ft/yr. Tongue River alluvium T is 9,000 to 60,000 gpd/ft.
- In-situ saturation: overburden mostly dry; Carney partially saturated to dry (saturated mainly in the eastern permit area); Masters partially saturated; Slater Creek alluvium partially saturated; Big Horn spoils partially saturated.

​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

- Recharge and water balance: Carney recharge from clinker contact, alluvial sub-crop, historic surface-mine pits, and Monarch-burn infiltration; Masters has no in-permit recharge or discharge boundary; vertical leakage is minimal because of the dry overburden/interburden and the low confining-clay K. Pre-mining drawdown of 40 to 80 ft on the eastern permit edge is attributable to 2000-2012 CBNG production.

WWC built a numerical groundwater flow model in 2014 to predict mining-induced drawdown. Following EQC review, WWC reconstructed the model in 2018; the 2018 model supersedes the 2014 model and is included in the permit. Material assumptions are: only the Carney and Masters coals are continuous saturated aquifers; the bounding claystones are confining units with vertical K consistent with the ASTM D 5084 results (about 1E-5 to 1E-4 ft/day); coal T, K, and S values are those from Addenda D6-8 and D6-15 in the permit, with porosity of 0.10; flow is from northwest recharge toward southeast down dip with fault-controlled local offsets; the Carney is recharged from clinker, alluvial sub-crop, historic mine pits, and Monarch-burn infiltration, while the Masters has no in-permit recharge or discharge; the Tongue River alluvium is hydraulically isolated from the Carney by the confining claystones; and the post-CBNG potentiometric surface is used as the initial condition so that mining-induced drawdown is additive to the existing depressed surface.

**7.4** **Geotechnical Data**

Ramaco typically does not collect geotechnical-based data at its mines, however, due to the auger/highwall mine method originally planned in Ramaco’s mining permit, existing coal exploration cores were sampled and analyzed for geotechnical parameters. Coal roof and floor samples were obtained for structural analysis from locations within the permit area during coal exploration coring. Laboratory strength analysis was conducted on four samples from two locations (R13-019 and R13-023). These specific sample sites were chosen due to their central locality to the permit area.

Existing core was also used to analyze tensile strength by method of the Brazilian Disk ASTM D3967. This method gauges tensile strength by subjecting a circular disk sample with a thickness to diameter ratio between 0.2 and 0.75 to diametral line compression to the point of failure.

Future rock strength analyses are not likely due to their lack of significance to the proposed truck-and-shovel mining methods. However, Rock Quality Designation (RQD) analysis of drill hole cores has recently been incorporated into Ramaco’s core logging practices. RQD

​

provides additional description of drill hole core that may help to further classify potential TCM mineralized zones.

An assessment of the quality of the non-coal material within the mineable sequence was prepared based on samples collected during the 2012 and 2013 coring programs. This data is used to determine the suitability of material used for final reclamation backfill in terms of establishing minimum groundwater quality levels and final revegetation success. The standard sample frequency for this non-coal was reduced from Guideline 1, based on agreement with WDEQ/LQD.

The current agreed frequency is one sample per 80 acres (eight per section), composited at 10-foot vertical intervals (instead of the 5-foot intervals normally required by Guideline No. 1), drawn from a combination of drill chips and coring. Twenty-five locations were sampled and seventeen were sent to the lab.

Tests performed were pH, Electrical Conductivity, Saturation %, Texture, Sodium Adsorption Ratio (or Exchangeable Sodium Percentage), Selenium, Boron, Nitrate-N, Molybdenum, Acid-Base Potential, Arsenic, and Total Organic Carbon.

**7.5** **Drilling Results**

Ramaco’s drilling programs at the Brook Mine demonstrate that both TCMs and coal exist at the site in quantity and quality that justify consideration of having reasonable prospects of economic extraction. The drilling results for TCM and coal commodities are discussed below.

**7.5.1** **TCM Commodities**

Drill hole samples were analyzed for a suite of TCMs with Table 7-3 showing a summary of the sample analysis statistics on a whole-rock basis.

​

​ ​

July 24, 2026 Page 59

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 7-3****TCM Sample Statistics**

The distribution of TCM samples by geologic domain (in descending stratigraphic order), are displayed in Table 7-4, with average metal concentrations on a whole rock basis. As shown in Table 7-4 there are varying sample counts by element due to the various sampling programs and inclusion or exclusion of elements for assaying within those sampling programs. This was primarily driven by the changes in market pricing for various critical minerals and as certain minerals increased in market value, they were added to the suite of elements assayed.

As can be seen in Table 7-3 and Table 7-4, the REE’s within the TCMs have the largest sample count as they were the initial target of exploration. As Gallium and Germanium began seeing elevated market pricing, those elements were added to the elements assayed. Similarly, as Scandium pricing increased, it too was added to the list of elements for assay.

​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 7-4****TCM Metal Sample Statistics by Domain**

Concentrations of Uranium (U) and Thorium (Th), radioactive contaminants, were sampled during pXRF scanning and with ICP-MS analyses. The results of both methods of analysis indicate these elements exist in low quantities. The results of the more accurate ICP-MS analyses for 3,857 Th samples and 4,399 U samples show an average of 11 ppm for Th and an average of 4 ppm for U. These levels are slightly above typical upper crustal abundance (10.5 ppm Th and 2.7 ppm U) as published by the International Atomic Energy Agency.

A schematic cross section (location identified on Figure 7-1) based on a selection of drill holes from within the exploration area showing the coal seam correlations as well as TCM sample grade histograms is presented on Figure 7-2. As can be seen in Figure 7-2, higher grade zones are exhibited above and below the coal seams and in some cases extend for upwards of 10 to 20 feet from the coal seam contact.

​

**7.5.2** **Coal Commodities**

The TCMs are associated with both coal intervals and intervals outside of the coal intervals. However, coal will be mined as a separate commodity from the TCM oxides and sold into thermal coal markets. The coal seams of interest at the Brook Mine are, in descending stratigraphic order, the Dietz 1, 2, and 3, Monarch, and Carney. The Masters Seam and several thinner unnamed underlying seams are not included in the current permit. A mine permit revision to include mining coal seams underlying the Carney Seam is required and will be prepared and submitted to state agencies once sufficient groundwater data has been collected in the aquifers below the Masters Seam. Ramaco has planned to drill and install the ground water monitoring wells required for this permit revision during the 2026 drilling season.

Within the current permit area, the Dietz seams are not prevalent, and they primarily exist to the south and east of the current permit area where they have not been eroded away. They generally do not exist in the permit area nor have they been oxidized, other than the eastern margin. The Monarch seam, similar to the Dietz, is only prevalent in certain portions of the permit area, specifically the northwest, east, and southeast. The Carney seams are fairly continuous across the permit area. The Carney Seam splits towards the western portion of the permit area. Table 7-5 shows drill hole statistics for the Brook Mine and includes areas to the south of the existing permit (see Figure 7-1), which explains the abundance of Dietz Seam data. This table also shows that the three Dietz seams have numerous splits where the Dietz seams exist. The Monarch and Carney seams are both relatively thick, each averaging approximately 15 feet, and are relatively clean with some partings found in certain areas.

​

July 24, 2026 Page 63

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 7-5****Drill Hole Coal Statistics**

Ramaco provided 92 drill holes with coal quality data. This data was used to interpolate coal qualities as shown in Table 7-6. The coal quality data for the Monarch and Carney seams shows a high Btu/lb, low sulfur, low ash thermal coal which is typical of PRB coal. The abundance of data for the Dietz seams in Table 7-6 is a result of the stratigraphic model’s inclusion of all drill holes for Ramaco-controlled property and encompasses areas south of the current mine permit area (see Figure 7-1). A portion of these drill holes are from areas that have previously been mined with historical mining concentrated in the south and eastern portions of the Brook Mine. Previous surface mining along the eastern edge of the Brook Mine was concentrated in the Dietz and Monarch seams with underground mining occurring along the southern and eastern edges of the Brook Mine in the Carney and Monarch seams respectively.

**Table 7-6****Drill Hole Coal Quality Summary**

**7.6** **Uncertainty in Resource Estimates**

Mining is a high risk, capital-intensive venture and each mineral deposit is unique in its geographic, social, economic, political, environmental, and geologic aspects. At the base of any mining project is the Mineral Resource itself. Potential risk factors and uncertainties in geologic data serving as the basis for deposit quantity and quality estimates are significant considerations when assessing the potential success of a mining project.

Geological confidence may be considered in the framework of both the natural variability of the mineral occurrence, and the uncertainty in the estimation process and data behind it. The mode of mineralization, mineral assemblage, geologic structure, and homogeneity naturally vary for each deposit. Structured variability like cyclic depositional patterns in sedimentary rock can be delineated mathematically with solutions like trend surface analysis or variography. Unstructured variability, in the distribution of igneous rock composition, for example, is more random and less predictable.

​

​ ​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The reliability of mineral tonnage estimation is related to uncertainties introduced at different phases of exploration. An exploration program comprises several stages of progressive data collection, analysis, and estimation, including:

- Geological data collection
- Geotechnical data collection
- Sampling and assaying procedures
- Bulk density determination
- Geological interpretation and modeling
- Tonnage and quality estimation
- Validation
- Confidence Classification

Error may be introduced at any phase. Data acquisition and methodologies should be properly documented and subject to regular quality control and assurance protocols at all stages, from field acquisition through resource estimation. Managing uncertainty requires frequent review of process standards, conformance, correctional action, and continuous improvement planning. Risk can be minimized with consistent exploration practices that provide transparent, backwards traceable results that ultimately deliver acceptable resource estimates for tonnage and quality.

As discussed in Sections 8 and 9, it is WEIR’s opinion that Ramaco’s methodology of data acquisition, record-keeping, and QA/QC protocols are adequate and reasonable for tonnage and grade estimation related to TCMs within the Brook Mine.

The drill hole data and quality assays of TCM attributes at the Brook Mine are demonstrated to be professionally developed, well maintained, quantitative, and qualitative data. WEIR finds no material reason, regarding geologic uncertainty, that would prohibit acceptably accurate estimation of mineral tonnage or grade.

**7.7** **Additional Commodities**

In addition to TCM commodity interests, there is subbituminous coal that is of economic interest within the Brook Mine. While TCM resources are present both within and outside of the coal seams, this TRS only considers those TCMs present outside of the coal seams and considers the coal to be a separate product from the TCMs. Therefore, this TRS includes estimates for both TCM and coal tonnage and quality.

​

​ ​

July 24, 2026 Page 66

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

In addition to the TCMs identified in this report, the following CMOs are present within the property and have been assayed with the samples collected:

- Yttrium
- Lanthanum
- Cerium
- Samarium
- Europium
- Gadolinium
- Holmium
- Erbium
- Thulium
- Ytterbium
- Lutetium

At present market conditions, these CMOs do not demonstrate Reasonable Prospects for Economic Extraction.

**7.8** **Conclusions**

Drilling results presented in this TRS demonstrate TCM concentrations which support further evaluation. The drilling results also demonstrate a high-quality thermal coal that warrants further evaluation.

WEIR did not have direct involvement with the implementation or supervision of Ramaco’s drilling or sampling programs. To the best of WEIR’s knowledge and observations, Ramaco’s exploration drilling, sample collection, preparation, security, and testing protocols are well documented and sufficient to provide consistent, reliable, and verifiable data. These protocols are planned to be maintained and improved throughout any subsequent extensions of the current exploration program.

The adequacy of sample preparation, security, and analytical procedures are generally unknown for the coal exploration holes that were drilled prior to Ramaco acquiring the property. However, the geologist’s logs for these holes contain sampling descriptions and lithologic descriptions that are sufficiently detailed to ascertain that an experienced geologist supervised the drilling and sampling, and WEIR supports the use of these drill holes to better define the structure of the deposit.

​

Having reviewed the details of each drilling and sampling program, WEIR finds the planning, implementation and supervision of Ramaco’s coal drilling and sampling programs to be consistent with industry standards, and is sufficient and relevant for use in the estimation of coal resources.

Ramaco’s initial CMO exploration and sampling regime was targeted to determine if sufficient quantities of elevated CMO mineralization were present on the property to warrant additional exploration. Based on this exploration, the initial samples of CMOs were conducted on a targeted basis until which point, Ramaco had determined that sufficient mineralization was present on the property and adjusted their drilling and sampling protocols to collect systematic data across the property. While the initial CMO drilling and sampling was conducted outside of normal industry standards, Ramaco has altered their drilling and sampling regime to align with current industry best practices and as such, WEIR finds that the TCM data collected is sufficient for estimation of TCM resources in the Inferred category.

**8.0** **Sample Preparation, Analyses, and Security**

**8.1** **Sample Preparation Methods, Analysis, and Quality Control**

Relative to the drilling overseen by Ramaco, once 3-inch diameter core samples are obtained, the cores are placed in plastic sleeves or tubing, measured and marked every two feet, photographed, and logged. The sleeved cores are transferred to a cardboard core box and labeled. Full core boxes are closed, secured, and transported to one of two secure storage locations. At the secure locations, the full boxes are checked in and added to the secure storage location inventory. Subsequently, and at the Ramaco iCAM secure location, cores are logged by geologic technicians and then reviewed by a professional geologist.

For preparation of ICP-MS analysis, the geologic technician logs the core within lithological boundaries. Once logging of the drill hole is completed, a sampling list is made. This sample list is determined by the current sampling regimen (currently, 5 feet above and below coal seams with 2 feet sampled into the coal seam). Samples are chosen within lithology boundaries and kept as close to one foot thick as possible. Then intervals are measured, marked, and split in half (currently splitting is done by hand with hammer and wide chisel by a staff geologist). Once core has been split in half, half of the core is put into a corresponding labelled sample bag and placed in a box to be shipped to the lab for analysis. The sample bag is recorded into which box in the shipment it resides. The other half of the core stays within the core box and is kept for record, and if needed, for re-logging. The ICP-MS analysis protocol utilized in the sampling of the Brook Mine drill holes provides accurate data relative to the concentrations of all TCMs.

**8.2** **Laboratory Sample Preparation, Assaying, and Analytical Procedures**

Third-party ICP-MS testing has been conducted at the independent ISO/IEC 17025-accredited commercial laboratories listed in Table 8-1 as follows:

​

​ ​

July 24, 2026 Page 69

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 8-1****ICP-MS Testing Laboratories**

The NETL served as the initial laboratory for Ramaco’s ICP-MS testing, however, for the 100-hole exploration program, Ramaco utilized Hazen, UND, and SGS interchangeably based on availability at each facility.

All of these laboratories have documented procedures on chain of custody verification and sample receipts, login, preparation, storage, and disposal, and these laboratories are also ASTM certified.

The NETL and SGS both utilize the ICP-Mass Spectrometry (ICP-MS) technology for elemental analysis, employing a Sodium Peroxide Fusion process in preparing samples for testing. The UND utilizes an ICP-Optical Emission Spectrometry (ICP-OES) technology for elemental analysis, employing microwave acid digestion in preparing samples for testing.

The minimum limits of detection associated with each laboratory elemental ICP-MS analysis are summarized in Table 8-2 as follows:

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 8-2****ICP-MS Assay Minimum Limits of Detection**

**8.3** **Quality Control Procedures and Quality Assurance**

Quality Control is generally analyzed on a 10 percent basis with Certified Reference Materials (CRMs), sample duplicates, Continuing Calibration Verification (CCV), and blanks. Ramaco has historically relied on the quality control procedures implemented by each laboratory but is in the process of developing and implementing their own quality control procedures for use in future sampling. As part of this TRS, WEIR reviewed quality assurance and quality control (QA/QC) procedures of the SGS laboratory.

**8.3.1** **Certified Reference Material**

The SGS laboratory utilized three internal CRMs (GRE-005, REE-003, and REE-2) that were inserted at a frequency of one per analytical batch (typical analytical batches are approximately 60 samples) and analyzed alongside project samples to monitor analytical accuracy and detect calibration drift across the program. Across the period of record (March 2025 through April 2026), 32 CRM analyses were reported for each standard. Results were provided as percentage recoveries (bias estimates) relative to the laboratory’s expected values rather than as raw assay results, and process control charts (X-charts) were constructed for each element on each standard. For GRE-005, mean recoveries were within ±5 percent of expected values for the principal REEs (e.g., Y avg = 100%, La avg = 97%, Ce avg = 96%, Yb avg = 101%), with upper and lower control limits generally falling within ±10 percent of the mean. A discrete shift in the central tendency was observed beginning at sample position 10-11 (February 3, 2026) and was visible on all three CRMs to varying degrees, with the largest deviations on GRE-005; this pattern is interpreted as a re-calibration of the analytical instrument rather than a sample-handling problem. Select X-charts are presented on Figure 8-1.

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Figure 8-1****GRE-005 CRM X-Charts**

Two limitations were: (1) raw assay values and the certified grade ranges of the three CRMs were not disclosed by the laboratory, so the standards’ coverage of the project’s anticipated economic grade range cannot yet be confirmed; and (2) the date and time of analysis at the digestion/instrument level were not provided in the laboratory metadata. Both items have been requested from the laboratory and will be addressed in the next data release.

**8.3.2** **Duplicates**

Analytical duplicates are inserted by SGS at a frequency of approximately one per analytical batch and are used to estimate the precision of the assay results. WEIR reviewed 128 duplicate samples inserted by SGS for analysis. Minimum and maximum graphs were prepared for Gallium (Ga), Germanium (Ge), Praseodymium (Pr), Neodymium (Nd), Terbium (Tb), and Dysprosium (Dy). The graphs include a 10 percent limit line (solid red) and a 20 percent limit line (dashed red) and are shown on Figure 8-2:

​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Figure 8-2****Duplicate QQ Plots**

Across the period of record (March 2025 through April 2026), 128 duplicate pairs were generated; the duplicate is identified within the laboratory data stream by an “a” / “b” suffix and a D1 designator and is processed concurrently with the parent sample through the sodium peroxide fusion/ICP-MS workflow. Precision is estimated using the 90th percentile of the absolute relative difference (ARD%) calculated on duplicate pairs in which both results exceed thirty times the lower detection limit (LDL); this approach is consistent with industry practice and allows direct comparison of precision between elements and between programs. The estimated precision for the principal rare earth elements is summarized in Table 8-3.

**Table 8-3****Estimated Precision by Element**

​ ​

July 24, 2026 Page 73

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

On a min-max basis, the majority of duplicate pairs fall inside ±20 percent of the parent value, and most lie inside ±10 percent. The estimated precision values fall in the range of approximately ±11-15 percent, with gallium at the upper end. These values are within the range expected for trace critical mineral assays at the grades observed and are considered acceptable for the purposes of this TRS. A principal limitation of the duplicates study is that the duplicate population covers a narrow and relatively low-grade range; precision at potentially economic grades therefore cannot be extrapolated with confidence from the current dataset, and additional duplicates spanning a wider grade range are recommended for future drilling programs.

**8.3.3** **Instrument Calibration**

Calibration of the ICP-MS instrument is verified at the start of each analytical batch and is monitored through the batch by means of a second-source initial calibration verification standard (2nd Source ICV). The 2nd Source ICV is a 10 ppm reference solution prepared from a stock independent of the calibration standards, providing an unbiased check on the calibration curve and on instrumental drift between batches. Thirty-two 2nd Source ICV analyses were reviewed across the period of record. Recoveries cluster tightly around the 10 ppm target for the principal rare earth elements, with the great majority of results falling within ±10 percent of the nominal concentration and no sustained directional drift outside that envelope. Three batches reported on February 3, 2026 (batches 2600986 / 2600987 / 2601002) returned anomalous CRM, blank, and 2nd Source ICV results in the same window in which the calibration shift was observed and have been flagged for laboratory follow-up; pending that explanation, results from these batches are reported but treated with caution for resource purposes. Subject to receipt of the raw 2nd Source ICV data, certified values for the three CRMs, and the laboratory’s response on the February 3, 2026 batches, WEIR is of the opinion that the QA/QC procedures applied by SGS are consistent with industry practice for rare earth element exploration and that the analytical data are of suitable quality to support the TCM Inferred Resources contained in this TRS.

**8.3.4** **Reagent Blanks**

Reagent blanks are inserted by SGS at a frequency of approximately one per analytical batch and are used to monitor the analytical workflow for cross-contamination, reagent contamination, and instrument carry-over. Thirty-three blank analyses were reported across the period of record. With the limited exceptions noted below, blank results are at or below the lower detection limit for the suite of elements of interest, and there is no evidence of systematic

​

​

contamination within the analytical process affecting the project samples. Two specific exceptions were identified: (1) the blank reported with batches 2600986 / 2600987 / 2601002 on February 3, 2026 returned anomalous results across multiple elements in the same window in which a calibration shift was observed in the certified reference materials and the second-source initial calibration verification, and (2) gallium results in three blanks from batch 2500791 reported on 14, 17, and 18 of November 2025 were elevated to between approximately 10 and 16 ppm and are interpreted as analytical errors rather than evidence of program-wide contamination. Both items have been identified for SGS, with explanation pending. A separate reporting observation, that a portion of blank results were returned as positive values below the LDL or as negative numbers, has also been raised with the laboratory; WEIR recommends that all such results be reported as “<LDL” in subsequent data releases. Subject to receipt of the laboratory’s response on the items above, the blank performance is considered consistent with industry practice for rare earth element exploration and adequate to support the conclusions of this TRS.

**8.4** **Sample Preparation, Security, and Analytical Procedures Adequacy**

The verification procedures described above did not identify any systemic error, transcription error, or systematic bias in the resource database that would prevent its use as the basis for an Inferred Mineral Resource estimate. Analytical precision estimated from the duplicate population is within the range typically expected for trace critical mineral assays by sodium peroxide fusion/ICP-MS at the grades observed and is adequate to support an Inferred classification. Reagent blanks, with the documented exceptions of the February 3, 2026 batch group and the three elevated gallium values in batch 2500791, show no evidence of systematic contamination of the project sample stream. The principal items requiring laboratory follow-up, provision of raw standard data, certified standard grades, date-and-time-of-analysis metadata, an explanation of the February 3, 2026 batch anomaly, and reporting of all sub-LDL values as “<LDL”, have been formally raised with SGS by Ramaco, and WEIR recommends that Ramaco implement an externally-controlled QA/QC program (blind insertion of certified reference materials, coarse blanks, and pulp duplicates by Ramaco geologists at industry-standard insertion rates, typically on the order of 5 percent of routine samples for each control type) for all subsequent drilling campaigns and review results in a timely manner to catch any anomalous samples as quickly as possible and determine the source of the anomalies.

WEIR finds that the TCM samples have been collected and analyzed in a manner that is sufficient for estimation of TCM Inferred Resources.

**9.0** **Data Verification**

**9.1** **Data Verification Procedures**

Ramaco provided WEIR copies of all available drilling records related to its Brook Mine, which included Excel spreadsheets, driller’s log, field geologist’s logs, core photographs, quality results sheets from the qualitative analysis laboratories, as well as drawing files or PDFs of the e-logs. Each hole in the database was individually checked by WEIR against a copy of the driller’s and/or geologist’s log to confirm data accuracy.

Geological reviews performed by WEIR included:

- Drill hole lithology database comparison to geophysical logs
- Drill hole TCM and coal quality database comparison to quality/assay certificates

After completing the precursory verifications and validations described, the drill hole data was loaded into Datamine’s MineScape® Stratmodel, a geological modeling software. MineScape provides robust error checking features during the initial data load, which include confirmations of seam continuity, total depth versus hole header file data, interval overlap, and quality sample continuity with TCM zones. Once the drill hole data was loaded, a stratigraphic model was created. A block model was subsequently produced using zones from the stratigraphic model which contains all TCM concentrations at coordinates of corehole analyses.

Further verifications were then possible, which included:

- Creating cross sections through both the stratigraphic and block models to visually inspect if anomalies occur due to miscorrelation of seams and the associated TCM mineralization immediately above and below the coal seams
- Creating structural and quality contour plots to visually check for other anomalies due to faulty seam elevations or quality data entry mistakes in the drill hole database

Typical errors that may impact resource estimates relate to discrepancies in original data entry, and may include:

- Incorrect drill hole coordinates (including elevation)
- Mislabeled drill hole lithology

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

- Unnoticed erroneous quality analyses where duplicate analyses were not requested
- Excessive drill hole core loss

WEIR conducted a detailed independent geological evaluation of data provided by Ramaco to identify and correct errors of the nature listed above. Where errors are identified and cannot be successfully resolved, it is WEIR’s policy to exclude that data from the geological model.

The pXRF scanning technology only provides reliable analysis of Lanthanum, Cerium, and Yttrium (LaCeY). It does not detect or accurately determine the concentration levels of most of the remaining REEs. As such, no pXRF data was incorporated into the geological model or Mineral Resource database utilized in estimating TCM tonnage and grade, but rather, the model relied on results of the ICP-MS sampling analyses. All available ICP-MS sample analyses were included in the drill hole assay/quality database.

The resource database underpinning the TCM estimate at the Brook Mine consists of three principal digital files maintained by Ramaco and reviewed by WEIR: a drillhole collar file (hole identifier, easting, northing, surface elevation, and total depth), a lithology log and lithologic type, and a multi-element assay file reporting yttrium, gallium, germanium, Scandium and the lanthanide series (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu), together with tantalum, thorium, and uranium, all determined by sodium peroxide fusion and ICP-MS at lower detection limits ranging from 0.05 ppm (most lanthanides) to 2 ppm (uranium). WEIR has performed data verification on this database to a level commensurate with industry-accepted practice for an Initial Assessment supporting an Inferred Mineral Resource.

WEIR performed the following verification steps on the resource database. First, WEIR reviewed and audited Ramaco’s written sampling and core-handling procedures (logging within lithologic boundaries, lithology-controlled sample selection, half-core sampling of nominal one-foot intervals extending five feet above and below each coal seam and continuing at two-foot intervals through the coals, retention of the remaining half-core in the original core box for verification, and chain-of-custody documentation linking each sample bag to its shipment box) and confirmed that these procedures are reasonable to support Inferred Mineral Resource classification. Second, WEIR loaded the collar, lithology, and assay files into the resource database management system and ran a battery of internal-consistency checks, including hole-name uniqueness, monotonic and non-overlapping interval depths, lithology-to-interval consistency, agreement of total interval length with reported total depth, plausibility of collar coordinates against the property polygon, and screening for out-of-range, blank, or

​

​ ​

​ ​ ​

​

below-detection-limit assay values. Third, WEIR performed random spot checks of digital records against the original laboratory certificates of analysis to confirm that values had been transferred to the database without transcription error. Fourth, WEIR performed independent geologic plausibility checks by inspecting a representative subset of the retained half-core and comparing logged lithology against the corresponding digital lithology log. Finally, WEIR reviewed the SGS laboratory QA/QC dataset and evaluated the three reference standards (GRE-005, REE-003, and REE-2), the population of approximately 128 analytical duplicate pairs, the reagent-blank population, and the second-source initial calibration verification (2nd Source ICV) population, and is summarized in Section 8.3 of this TRS.

Further to these desktop verifications, WEIR personnel conducted several site visits to the property with the most recent site visit conducted on April 28, 2026 where drilling and sampling procedures were observed and found to be in accordance with industry accepted practice. Additionally, several previously drilled holes were viewed and collar coordinates verified and confirmed with handheld GPS.

**9.2** **Data Verification Limitations**

Limitations of data verification included incomplete or missing records for some drill holes. The primary reason for this situation is incomplete data transfers upon change in property ownership. Based on its modeling results, WEIR found some of the drill holes with incomplete data, for example lacking geologist’s logfiles and/or e-logs, to be consistent with the deposit and appropriate to include in WEIR’s geological model.

Verification of assay results was subject to the following limitations, which WEIR has taken into account in forming the opinion stated below:

- Raw analytical results for the three reference standards were not provided by the laboratory; the values supplied appear to be percentage recoveries (bias estimates) referenced to the laboratory’s internal expected values, which are sufficient for process control but do not permit WEIR to independently confirm absolute analytical accuracy.
- The certified grades and the grade ranges of the three reference standards are not yet documented, so WEIR cannot yet confirm that the standards bracket the deposit’s anticipated economic TCM grades.
- Date and time of analysis are not reported in the laboratory metadata accompanying the digital results, which limits the ability to correlate analytical drift with specific instrument or operator changes. It is noted, however, that the calibration shift centered

​

​ ​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

on February 3, 2026 is visible across all three standards and coincides with the anomalous batch group (2600986 / 2600987 / 2601002), and samples have been flagged in that batch group for confirmation by the laboratory.

- The grade range covered by the duplicate population is narrow and lies near the lower end of the deposit’s reported grade range, so analytical precision at the upper end of potentially economic TCM grades cannot, at present, be extrapolated with high confidence from the current duplicate dataset.
- The QA/QC program operating during the period of record is laboratory-internal; Ramaco geologists have not yet inserted blind certified reference materials, blind coarse blanks, or blind pulp duplicates into the sample stream, meaning the QA/QC dataset does not yet quantify variability introduced upstream of the laboratory’s receiving department (sample preparation, packaging, transport, and laboratory log-in).
- The laboratory’s 2nd Source ICV data type is not yet formally documented in support provided by SGS.

None of these limitations prevented WEIR from completing the verification work required to support an Inferred Resource classification; each is, however, a matter that must be resolved before any portion of the Mineral Resource can be advanced to the Indicated or Measured category.

**9.3** **Adequacy of Data**

The collar, lithology, and assay files are internally consistent and reconcile with their underlying source records on the sampling basis tested.

It is WEIR’s opinion that the adequacy of sample preparation, security, and analytical procedures for holes that were drilled by Ramaco after acquiring the property are acceptable and that these procedures meet typical industry standards. Ramaco employs detailed processes and procedures, described in Section 8, that are followed each time a core hole is to be sampled. The geologist’s logs for these holes contain sampling descriptions and lithologic descriptions that are sufficiently detailed to ascertain that an experienced geologist supervised the drilling and sampling. Ramaco TCM quality analyses performed by the NETL, SGS, Hazen, or UND are to ASTM standards, as noted in Section 8.

The adequacy of sample preparation, security, and analytical procedures are generally unknown for drill holes that were drilled prior to Ramaco acquiring the property in 2011. However, the geologist’s logs for these holes contain sampling descriptions and lithological

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

descriptions that are sufficiently detailed to ascertain that an experienced geologist supervised the drilling and sampling. All TCM quality analyses have been performed since Ramaco’s acquisition of the property and these analyses have followed the procedures detailed in Section 8. The legacy drill hole information was not used for TCM quality analyses; however, the drill holes were used for coal seam structure and thickness modeling. Model verifications further support WEIR’s confidence that a representative, valid, and accurate drill hole database and geological model(s) have been generated for the Brook Mine that can be relied upon to estimate TCM tonnage to an accuracy that is acceptable for this report’s specified standards.

On the basis of the verification procedures described above, the analytical precision demonstrated by the duplicate population, the absence of evidence of systematic contamination or bias outside the documented and disclosed exceptions, the consistency of the digital database with the original source records inspected on a sampling basis, and the conservative Inferred Mineral Resource classification adopted, WEIR is of the opinion that the resource database is adequate, in its current form and subject to the limitations disclosed in this section, for the purposes for which it is being used in this TRS, namely the geological characterization of the Brook Mine property and the estimation and reporting of an Inferred Mineral Resource as an Initial Assessment under Item 1302(d) and Item 601(b)(96)(iii)(A) of Regulation S-K.

Consistent with the definitions of an Inferred Mineral Resource and an Initial Assessment in §229.1300, WEIR cautions that an Inferred Mineral Resource has the lowest level of geological confidence and may not be converted directly to Mineral Reserves. Closure of the verification limitations and recommendations identified above will be required before any portion of the Inferred Mineral Resource can be considered for upgrade to a higher Mineral Resource confidence category.

**10.0** **Mineral Processing and Metallurgical Testing**

**10.1** **Mineral Processing, Testing, and Analytical Procedures**

Ramaco has been performing preliminary metallurgical testing on Brook Mine samples since May 2023. These testwork programs were executed at SGS Lakefield in Canada (SGS) and Hazen Research Inc. (Hazen) in Colorado.

Mineralogical analysis at Hazen via quantitative x-ray diffraction (QXRD), quantitative evaluation of materials by scanning electron microscopy (QEMSCAN) and scanning electron microscopy (SEM) revealed a predominantly aluminosilicate structure comprised of a mineral mixture of kaolinite, K-felspar, muscovite, and quartz.

Analytical and mineralogical assessments have clearly shown that Scandium, Gallium and Germanium are associated with aluminosilicates where the Gallium specifically displaces aluminum by isomorphous substitution and scandium possibly through interlayer or ferric isomorphous substitution. Germanium is present by isomorphous substitution of silicon in the aluminosilicates. REEs were identified to be associated with monazite and xenotime. Several weaker acids like citric acid and oxalic acid as well as stronger acids like hydrochloric acid and sulfuric acid were all tested at Hazen and SGS. Stronger acids provided good extractions for the REE’s but were unable to achieve high extractions for Scandium, Gallium and Germanium.

Extraction of Scandium, Gallium and Germanium are only possible through the destruction of the aluminosilicate matrix. Acid alone is ineffective in achieving this and the leaching testwork has verified this assumption. Furthermore, alternate lixiviants were effective at dissolving aluminosilicates and extraction of the critical minerals more than doubled and even tripled compared to acid only extractions.

Deleterious elements include any element that is acid or alkali consuming but does not contribute to the product revenue. Iron and aluminum are unavoidable in this context and aluminum is targeted to extract entrained critical elements. Quartz is present but is unreactive in this process.

Approximately 40 bench scale leach tests were conducted on the feed samples. Grind size, reaction temperature, residence time, and slurry solid concentrations were varied to determine optimal leach conditions.

​

​ ​

July 24, 2026 Page 81

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

A pre-treatment followed by a two-stage leach achieved higher recoveries for TCMs. The details of the reagent sequence used to achieve high extractions were reviewed by this QP, however those details are considered Ramaco’s intellectual property and not fully detailed in this TRS.

Results of the testwork conducted by SGS and Hazen and as directed by Fluor, were incorporated into the conceptual process plant design basis described in the Fluor study. The Fluor study includes both a flowsheet design as well as the corresponding mass balance analysis generated from utilization of Metso’s HSC Chemistry Software to simulate various circuit performance.

Coal recovered at the planned Brook Mine will be sold as a run-of-mine (ROM) thermal coal product. As such, mineral processing and metallurgical testing do not apply.

**10.2** **Mineralization Sample Representation**

The bulk samples used for mineralogical, physical testing, and extractive leach tests include raw coal and other mineralized zones outside of the coal intervals. The various mineralization types across the deposit appear to be well represented in the bulk test samples. As the project advances, additional variability testing will be required to determine metallurgical response to different mineralization types to the selected flowsheet.

Samples selected for testing included the four primary mining-related zones across multiple coal seams. These include mineralized coal, “roof” and “floor” zones comprising carbonaceous clays and shales, and “partings” containing a mixture of mineralized coal, carbonaceous clays, shales and silts.

To ensure the samples reflected the broader deposit and mining conditions, sample selection focused on major coal seams and associated zones considered reasonably mineable within the deposit. These include the Dietz 3, Monarch, Carney, and Masters Seams.

Using a resampling program and geochemical data as the foundation for sample selection, continuity and consistency of target material across each seam and mining zone was evaluated. Emphasis was placed on identifying vertically continuous intervals that could provide representative material for hydrometallurgical testing and to support flowsheet development. By incorporating samples from multiple seams, stratigraphic zones, and drill holes distributed

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

across representative areas of each seam, the program was designed to capture both the vertical and lateral variability present throughout the deposit into a bulk deposit for scoping tests.

**10.3** **Analytical Laboratories**

The same laboratories identified in Section 8.2 were involved in mineral processing analyses and metallurgical testing. Please see Section 8.2 for further details.

The following two independent third-party laboratories performed comminution, pre-treatment, and multi-stage extractive leaching tests:

- Hazen Research, Inc. Hazen Research, Inc. is an employee-owned industrial R&D firm located at 4601 Indiana Street, Golden, Colorado 80403. The Hazen Analytical Laboratory holds certifications from various state regulatory agencies and from the US Environmental Protection Agency (EPA), participating in performance evaluation studies to demonstrate competence. Reference materials are maintained from NIST, CANMET, and the EPA to underpin analytical accuracy.
- SGS Canada Inc. - Minerals - Lakefield. The full registered name under Standards Council of Canada (SCC) accreditation is SGS Canada Inc. - Natural Resources - Minerals - Lakefield. The facility is located at 185 Concession Street, Lakefield, Ontario, K0L 2H0, Canada. The Lakefield laboratory conforms to the requirements of ISO/IEC 17025 for specific registered tests (the international standard for analytical testing laboratories). SCC accreditation has been held since 1995 (File No. 15254). The Lakefield facility serves as the Centre of Excellence within SGS’s global network of over 440 mining-dedicated laboratories and offices.

**10.4** **Relevant Results and Processing Factors**

Overall recovery for the initial block flow is driven predominantly by leach extractions and estimates for full scale recovery. Multi-stage leaching test results have yielded percentage recoveries of TCMs into the low 90s. The overall plant recovery of the TCMs averages 82 percent using downstream commercial scale recovery assumptions from benchmarks for similar flowsheets.

Optimum recoveries were achieved after feed pretreatment followed by muti-stage leaching. Various lixiviants, reaction temperatures and residence times were tested. Grind size P80 varied from 10 microns for the ultrafine grind to 200 microns. The bench scale test program

​

​ ​

July 24, 2026 Page 83

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

did not include additional testing for recovery optimization. Overall plant recoveries were discounted by 1-3 percent to account for losses anticipated in commercial plant operations and presented in Table 10-1.

**Table 10-1****Estimated Overall Plant Recovery by Element**

The bulk samples TCM head grade used for metallurgical testing was within 6 percent of the mill feed grade generated from Mineral Resources within the optimized pit shell.

Further tests are planned in future phases to complete full flowsheet bench scale testing and variability testing to optimize and determine full flowsheet recoveries. Recovery percentage highly influences project profitability.

**10.5** **Data Adequacy**

The Brook Mine deposit hosts rare earths and critical minerals in minerals seen in many other conventional rare earth deposits. The flowsheet uses conventional unit operations found in other conventional mineral processing and hydrometallurgical flowsheets. A specific sequencing of these conventional unit operations is used to affect favorable metallurgical response.

The impact of deleterious elements on final product purity was not tested at this phase of the project but it should be tested in future phases of testing.

The analytical procedures used in the analysis are conventional industry practice. Recovery assumptions are reasonable, with data adequacy and testing suitable to support an Initial Assessment of the TCM Mineral Resources for the Brook Mine.

​

**11.0** **Mineral Resource Estimates**

The point of reference of the TCM and coal resources, as of December 31, 2025, are reported as in-place resources (point of reference). Coal and TCM Mineral Resources are reported in the Inferred category for tonnage and grade/quality, in accordance with Regulation S-K Item 1302(d)(1)(iii)(A).

**11.1** **Key Assumptions, Parameters, and Methods**

Based on WEIR’s review and evaluation of the data relative to the Brook Mine, relevant technical and economic factors were applied to the Mineral Resource estimates to ensure reported Mineral Resource tonnage and grade/quality has reasonable prospects for economic extraction. General resource classification criteria and parameters are as follows:

- All resources (TCM and coal) were estimated on an in-situ basis as of December 31, 2025, utilizing a data cut-off date of June 30, 2025.
- All resources (TCM and coal) are based on recovery of the TCM and coal resources from the Lower 7 Seam and above.
- Previous underground mine workings within the coal measures were excluded from the resource estimates based on a 200 ft buffer around mapped historical mining extents.
- TCM and coal tonnage estimates were limited to areas of mineral control within the vicinity of the Brook Mine permit boundary and avoided surface encumbrances such as the Interstate Highway south of the permit as well as the surface mining exclusion area within the Padlock Surface Use Agreement along the southeast side of the permit.
- Coal density (pounds per cubic foot) is based on apparent specific gravity data from analyses of drill hole samples and channel samples, where available. Otherwise, it is based on raw coal ash (dry basis) using the formula [1.25+(Ash/100)]. The TCM containing strata utilized an average relative density of 2.4.
- TCM and coal resources were constrained within a revenue factor 1.0 pit shell based on the results of a pit optimization exercise.
- For the purposes of this TRS, WEIR assigned an Inferred confidence category to all TCM and coal resources due to the preliminary nature of the geological study and associated TCM processing study and design work. TCM grade continuity is assumed based on the present mineralization assumption of mineralized fluids moving through the coal seams and depositing TCM mineralization in the strata immediately above and below the coal seams as discussed in Section 6.

​

**11.1.1** **Resource Database**

The resource database used to support the Mineral Resource estimates comprises drill hole collar, survey, lithology, and assay records that have been verified by WEIR as described in Sections 7, 8, and 9. The database cutoff date for the current estimate is June 30, 2025. Drilling and sampling protocols, assay procedures, and QA/QC results are summarized in Sections 7, 8, and 9, respectively.

As noted in Section 7, Scandium was not consistently assayed until late 2024/early 2025 with the database containing only 243 Scandium assays. As such, Ramaco developed a regression formula utilizing 231 of the 243 Scandium assays to predict Scandium values for samples where Scandium was not previously assayed. The formula utilized is based on total rare earth element (TREE) concentration consisting of the following elements: Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Tm, Yb, and Y. The Scandium regression formula is as follows:

This estimation was then capped on the downside at zero to eliminate negative assays in samples with low TREE values. A comparison of the distribution of assayed Scandium versus the calculated Scandium is presented in Table 11-1:

**Table 11-1****Scandium Regression Statistics**

Additionally, 12 samples in the database were excluded from modeling due to having a zero sample thickness. The QP considers the resultant sample database to be of sufficient quality and quantity to support the Inferred Mineral Resource classification reported in this TRS.

​

**11.1.2** **Coal Stratigraphic Grid Model**

Coal Mineral Resources were estimated using a stratigraphic grid model in which each target seam is represented by separate top and bottom elevations, density and quality grids. The grid model was constructed in Datamine’s MineScape® software package at a grid cell size of 50 ft square for the structure and 200 ft square for the quality parameters. Section 6.3 details the coal stratigraphic grid model construction process.

The grid model was validated by visual inspection of the seam roof and floor grids against drill hole intercepts and comparison of modeled seam thicknesses against drill hole intercepts. Cross sections were prepared across strike and dip and reviewed to confirm seam correlations and structural features were accurately reflected in the gridded model from the source drill hole data.

**11.1.3** **TCM Block Model Construction**

The TCM Block Model was constructed using Datamine’s MineScape ® Software package as described in Section 6.3.2. TCM mineralization zones were limited to five feet above and below the modeled coal seams for interpolation of TCM grades. TCM assays used to interpolate the model were coded with the zone they were associated with to ensure assays associated with one coal seam were not used to inform a mineralized zone of another seam.

TCM grades were interpolated into the blocks using sample thickness weighting to account for variation in sample thickness from the various sampling campaigns as described in Section 7. Inverse Distance Squared was used as the interpolation function with the following parameters:

- Search Ellipsoid: X and Y <= 2,800 ft, Z <= 5 ft
- Minimum samples per model cell: 3
- Minimum octants: 1
- Minimum samples per octant of 2 with a maximum of 3

The resultant TCM block model was validated using a combination of visual inspection against the assay database and comparison of interpolated block grades to thickness-weighted average sample grades by domain as presented in Table 11-2. Overall, modeled grades compared favorably to the sample database with most domains and elements being within +/- 20 percent The Low 7 Interburden exhibited higher variances due to the low sample count (90 samples).

​

**Table 11-2****Average Block Model versus Sample Statistics**

The validation results indicated that the model sufficiently reproduces the sample analyses on a domain-by-domain basis and is acceptable for use in estimation of Inferred Mineral Resources.

**11.2** **Technical and Economic Factors for Determining Reasonable Prospects of Economic Extraction**

Several factors are involved in determining reasonable prospects of economic extraction for both TCMs and coal at the Brook Mine. These items are summarized below:

​

​ ​

July 24, 2026 Page 88

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

- Coal sales price: The Free on Board (FOB) Mine coal sales price of $13.23 per tonne was utilized in assessing the economic extraction of the Brook Mine coal, based on sales of a thermal coal product.
- TCM sales price: The FOB Mine TCM sales prices used in assessing the economic extraction of the planned Brook Mine TCMs are based on assumptions from Ramaco as presented in the Fluor Study and as detailed in Table 11-3.
- Operating costs for mining and processing are presented in Table 11-4, and are discussed further in Section 18.

FOB Mine Sales pricing and recovery for each product are summarized in Table 11-3 as follows:

**Table 11-3****FOB Mine Product Pricing and Recoveries**

Coal and TCM pricing was provided by Ramaco and developed in a manner consistent with those described in Section 16. TCM pricing is based on Western Pricing for sales of TCMs produced outside of China. Pricing used in determining reasonable prospects of economic extraction is reflective of early 2025 market pricing as provided by Ramaco and deemed reasonable by WEIR. Ramaco developed the pricing based on the methodology and supply/demand forecasting as detailed in Section 16. As the TCM markets are in constant flux, pricing used in the economic analysis (Section 19) reflects pricing changes through the end of 2025 which exhibited continued growth through 2025, further confirming the reasonableness of the pricing shown in Table 11-3 for use in demonstrating reasonable prospects of economic extraction. The TCM pricing was held constant over the life of the Resource.

In order to demonstrate reasonable prospects of economic extraction, WEIR utilized Datamine’s Studio NPVS software to develop a series of nested pit shells based on the product pricing and recovery estimates in Table 11-3 and the physical and economic parameters shown in Table 11-4.

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 11-4****Pit Optimization Physical and Cost Parameters**

A mining cost adjustment factor (MCAF) of 0.9 was applied to the waste and TCM resource costs to account for the 45X Production Tax Credits that allow for a tax credit on the production of critical minerals in the amount of 10 percent of production and processing costs associated with domestic critical mineral production and processing. Further details on the 45X Tax Credits can be found in Section 19. The mining and processing costs were provided by Ramaco and deemed reasonable by WEIR based on general experience with other mining operations. The unit costs were held constant over the life of the Resource.

**11.3** **Estimates of Mineral Resources**

The Inferred Mineral Resources reported in this TRS are not Mineral Reserves and are considered too speculative geologically to have modifying factors applied to the Mineral Resources that would allow for conversion to Mineral Reserves. The QP responsible for the estimates has a reasonable expectation that the majority of the Inferred Mineral Resources could be upgraded to Indicated or Measured Mineral Resources with continued exploration. There is no certainty that any part of the Mineral Resources estimated will be converted into Mineral Reserves in the future. The Inferred TCM Mineral Resources, as of December 31, 2025, are reported as in-place resources (point of reference). TCM Mineral Resources are summarized in Table 11-5:

**Table 11-5****Summary of Brook Mine TCM Mineral Resources, as of December 31, 2025**

Notes:

- Coal and TCM resources are considered collectively in the evaluation of reasonable prospects of economic extraction with estimated revenues as follows: $850/kg Dy2O3, $770/kg Ga2O3, $2,435/kg GeO2, $130/kg Nd2O3, $130/kg Pr6O11, $3,750/kg Sc2O3, $3,000/kg Tb4O7, and $13.23/tonne coal.
- TCM processing recoveries are as follows: 82% Dy2O3, 67% Ga2O3, 94% GeO2, 92% Nd2O3, 92% Pr6O11, 70% Sc2O3, 94% Tb4O7. An overall recovery of 90 percent was applied to the coal.
- Mining costs of $1.33 per tonne were used for resource pit shell generation. A mining cost adjustment factor (MCAF) of 0.90 was used for TCM and waste rock types to account for the 45X production tax credit assumed.
- A Net Smelter Return (NSR) marginal TCM cutoff of $67.69 per metric tonne of rock was used to classify TCM resources as an Inferred Mineral Resource within the optimized pit shell. The marginal TCM cutoff consists of $69.80 per tonne of processing costs, $1.44 per tonne of G&A and $3.97 per tonne of TCM residue handling costs as well as an offset to the costs of 10 percent (-$7.52 per tonne) from the 45X production tax credit. *NSR* = (69.80 + 1.44 + 3.97) × (1 − 10%)
- TCM Resources were constrained within the revenue factor 1.0 pit shell described in Section 11.2.
- Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.

The pit optimization produced for the TCM resource included both coal and TCM resource costs and revenues generating ultimate surface to limit all resources within. As coal will be extracted from the pit as part of the TCM mining process, it is assumed that the coal will be

recovered and sold as a separate product to the TCMs. The coal resources, as of December 31, 2025, are reported as in-place tonnage (point of reference) and summarized in Table 11-6 as follows:

**11.4** **Mineral Resource Classification**

Mineral Resource estimates prepared for the Brook Mine are in accordance with SEC Regulation S-K Item 1302(d)(1)(iii)(A), which established definitions and guidance for Mineral Resources, Mineral Reserves, and mining studies used in the United States. The definitions relevant to the Mineral Resources are as follows:

Mineral Resource:

Mineral resource is a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A Mineral Resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

- *Inferred Mineral Resource* is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an Inferred Mineral Resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an Inferred Mineral Resource has the lowest level of geological confidence of all Mineral Resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an Inferred Mineral Resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a Mineral Reserve.

Geostatistical methods were applied to drill hole coal thickness and quality data for the Monarch and Masters Seam at the planned Brook Mine to develop variogram ranges (radii) used for coal resource classification. Variograms were generated for the Monarch, Carney, and Masters seams. An overall average between these seams resulted in WEIR selecting 1,000 and 3,000 feet for measured and indicated radii, respectively. Given the preliminary nature of this geological study, these radii were not used to determine confidence categories, but rather to support a reasonable assumption of lateral continuity to be applied in WEIR’s resource modeling of the Brook Mine.

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

All Mineral Resources reported in this TRS have been classified as Inferred. The Inferred classification reflects (i) sample spacing that is wider than what WEIR considers necessary to demonstrate the geological and grade or quality continuity required for an Indicated classification; and (ii) the early stage of project definition consistent with an Initial Assessment. No portion of the TCM or Coal tonnage has been classified as a Measured or Indicated Resource.

**11.5** **Uncertainty in Estimates of Mineral Resources**

Mining is a high risk, capital-intensive venture and each mineral deposit is unique in its geographic, social, economic, political, environmental, and geologic aspects. At the base of any mining project is the Mineral Resource itself. Potential risk factors and uncertainties in the geologic data serving as the basis for deposit volume and quality estimations are significant considerations when assessing the potential success of a mining project.

Geological confidence may be considered in the framework of both the natural variability of the mineral occurrence and the uncertainty in the estimation process and data behind it. The mode of mineralization, mineral assemblage, geologic structure, and homogeneity naturally vary for each deposit. Structured variability like cyclic depositional patterns in sedimentary rock can be delineated mathematically with solutions like trend surface analysis or variography. Unstructured variability, in the distribution of igneous rock composition, for example, is more random and less predictable.

The reliability of Mineral Resource estimation is related to uncertainties introduced at different phases of exploration. Resources meeting criteria for Measured, Indicated, and Inferred categories are determined by the quality of modeled input data, both raw and interpreted. An exploration program comprises several stages of progressive data collection, analysis, and estimation, including:

- Geological data collection
- Geotechnical and metallurgical data collection
- Sampling and assaying procedures
- Bulk density determination
- Geological interpretation and modeling
- Volume and quality estimation
- Validation
- Resource classification and estimation

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Error may be introduced at any phase. Data acquisition and methodologies should be properly documented and subject to regular quality control and assurance protocols at all stages, from field acquisition through resource estimation. Managing uncertainty requires frequent review of process standards, conformance, correctional action, and continuous improvement planning. Risk can be minimized with consistent exploration practices that provide transparent, backwards traceable results that ultimately deliver acceptable resource estimates for tonnage and quality.

Subsequent to the data cutoff date of June 30, 2025 and prior to the issuance of this TRS, additional drilling and assaying has been completed by Ramaco. WEIR has not incorporated this additional information into the modeling presented within this TRS, but has reviewed the data. WEIR compared the assay results of several drill holes completed in January 2026 to what was predicted by the existing TCM block model to determine if the model was working as expected. The results of this comparison for three holes in the southwest of the resource pit shell and several seam groups are shown on Figure 11-1.

**Figure 11-1****Model Prediction versus Drill Hole Comparison**

Figure 11-1 provides validation that the current TCM block model is reasonably accurate in predicting grades as the new assay results (orange lines) show similar spikes of high and low grades (Total Rare Earth Oxides plus Gallium, Germanium and Scandium oxides) at similar elevations and thicknesses. In hole 578514-NE-10C, a slight variation in seam elevations can

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

be seen however, the grade spikes are of similar orientation and magnitude between the new assays and the interpolated block model grades. This further validates the grade continuity of the TCM mineralization as drillhole 578514-NE-10C is approximately 250 feet away from the nearest set of samples used to inform the TCM block model.

In summary, WEIR has reviewed all geologic, metallurgical and geotechnical data inputs, collection protocols, sampling, assaying, and laboratory procedures serving as the basis for the deposit model, its interpretation, and the estimation and validation of the quantity and quality of TCM and coal resources within the Brook Mine. While the continuity of an Inferred Resource is by definition a low confidence assumption, current Coal and TCM continuity is supported by professionally developed, well maintained, quantitative and qualitative data. WEIR has considered all uncertainties involved in drilling and sampling methods, data processing and handling, geologic modeling, and estimation in the final classification in the Inferred Resource category and finds no material reason related to geologic uncertainty that prohibits estimation of Inferred Resources.

**11.6** **Additional Commodities or Mineral Equivalents**

There are no commodities or minerals of economic interest within the Brook Mine beyond the TCM and coal deposits discussed in this TRS.

**11.7** **Risks Regarding Technical and Economic Factors**

By definition, the quantity, grade, and continuity of Inferred Resources have low confidence.

The low confidence level associated with Inferred Resources is in part due to certain identifiable risks. At the Brook Mine, risks associated with Mineral Resource estimates include the following:

- Implied spatial and grade continuity of the TCM mineralization
- On-going seam and lithology correlation and structural definition
- Identification and quantification of faulting throughout the deposit
- Areas of low ICP-MS sampling coverage, in particular below the Masters Seam
- Geotechnical evaluations of surface mining feasibility and mineral recovery at significant depths
- Metallurgical testwork may not be fully representative of all mineralized domains and may result in variable TCM recovery

​

​ ​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

- TCM process plant may not meet design specifications resulting in lower throughput and/or higher costs
- Volatility of TCM and coal sales prices, coal resources are dependent on TCMs being economically mineable
- Significant variations in operating cost, processing recoveries, capital expenditures, and productivity can preclude the economic mineability of the Brook Mine
- Unforeseen changes in legislation and new industry developments could positively or negatively alter the performance of Ramaco by impacting thermal coal or TCM demand, mining regulations, permitting, and taxes

The QPs responsible for the Mineral Resource estimates believe all relevant technical and economic factors likely to influence the prospect of economic extraction can be resolved with further work.

​

**13.0** **Mining Methods**

The Brook Mine, as proposed in this TRS, will be a conventional truck-and-shovel open-pit mine. Material will be excavated with large hydraulic-shovels and loaded into haul trucks. Waste material, or burden, will be initially removed to stockpiles, however, once enough storage space is made available within the mining pits, burden material will be placed back into mined-out pits. Burden material will be removed to uncover both TCM Mineral Resources and thermal Coal Resources.

Coal will be mined using a standard truck/loader equipment spread (see Table 13-5). Coal mined from the pit will be placed in a stockpile and loaded onto rail cars or trucks. This same equipment spread will also be used to recover TCM Mineral Resources for transport to the process plant.

The overburden will require blasting for removal. However, it is anticipated that dozers will rip targeted TCM resources to facilitate loading and reduce dilution.

The Brook Mine permit, as currently approved by WDEQ/LQD, contemplates a combination of trench excavation plus ADDCAR-style highwall mining (HWM) of the Carney Seam, with limited surface mining. Ramaco intends to file a permit revision replacing the trench/HWM method with a convention truck-and-shovel open-pit mining method, additionally, the revised permit will incorporate mining provisions for additional coal seams and recovery of TCMs.

**13.1** **Geotechnical and Hydrological Models**

**13.1.1** **Geotechnical Model**

The geotechnical analysis developed historically for the Brook Mine centers almost entirely around HWM pillar stability and HWM-induced subsidence (Agapito Associates, Inc. 2018, AAI 2018). That body of work is therefore largely mining method-specific and must be updated for the revised open-pit mining plan.

Although the existing test program was designed around HWM pillar and roof characterization, certain underlying samples and laboratory data remain useful for open-pit slope and spoil design. The data set consists of:

​

​ ​

July 24, 2026 Page 99

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

- Geotechnical core hole 2017-4 (Boart Longyear, May 25, 2018, total depth 160 ft), drilled within the proposed mining footprint and shipped to the AAI rock-mechanics laboratory in Grand Junction, Colorado.
- Twenty uniaxial (unconfined) compressive strength (UCS) tests on the four principal lithologies (sandstone, mudstone-sandstone, mudstone, carbonaceous mudstone, plus coal), of which fourteen included measurement of Young’s modulus and Poisson’s ratio.
- Two axial point-load compressive strength tests and nine diametral point-load tests.
- Five slake-durability tests (second-cycle index) characterizing the carbonaceous mudstone, floor mudstone, and other moisture-sensitive lithologies.
- Bulk density and gravimetric moisture content on representative lithologies.
- Geologist’s logging supporting Coal Mine Roof Rating (CMRR) and Rock Quality Designation (RQD) determinations from core.

The 2017-4 geotechnical core hole data is summarized in Table 13-1 as follows:

**Table 13-1****Geotechnical Core Hole Statistics**

Overburden strength is moderate (UCS 2,500-3,060 psi in sandstone and mudstone), consistent with other PRB surface mines, supporting moderately steep but not aggressive pit-wall designs. The Carney Seam immediate overburden carbonaceous mudstone is weak and weathering-sensitive (slake durability 11.8 percent is very low under Franklin & Chandra 1971), and the pit-floor carbonaceous mudstone is also low-durability (26.8 percent) with 18 percent moisture. Both of these present constraints on bench-face stability, on trafficability of the pit floor under shovels and loaders, and on the quality of overburden that will form the spoil.

​

Several default geometries already exist in the current permit for ancillary features such as haul roads, stockpiles, and sediment-control structures, and remain directly applicable to truck-and-shovel operations. These are summarized in Table 13-2 as follows:

**Table 13-2****Ancillary Feature Geotechnical Parameters**

The defaults described in Table 13-2 were not derived from a site-specific pit-wall slope-stability analysis, rather, they reflect generic earthwork practice within PRB operations. While they are appropriate for ancillary cut/fill features, these defaults are not sufficient as design parameters for the final mining pit walls themselves.

WEIR recommends the following workflow for the Brook Mine truck-and-shovel mine plan:

- Final pit limit definition - Determine the revised pit-shell geometry (cut/fill volumes, ramp configuration, bench heights) so the geotechnical investigation can be sited along the actual proposed wall lines.
- Pit-wall geotechnical drilling - Core holes along the proposed final highwall, with full geotechnical logging (UCS, point-load, slake, density, moisture, RQD, discontinuity orientation, condition and infill), plus shallower auger / split-spoon holes for trafficability characterization of the immediate floor.
- Structural mapping - ATV/OTV imaging of core holes; surface scanline or window mapping of any exposed Tongue River Member benches; stereographic analysis of discontinuity sets relative to the proposed pit-wall orientations.

​

​

- Slope-stability analyses - Limit-equilibrium analyses for circular and non-circular failure surfaces; kinematic analyses (planar, wedge, toppling) for rock-mass-controlled sectors; numerical analyses for any critical or sensitive sections.
- Spoil-pile stability analyses - Site-specific spoil strength; foundation-condition mapping; static and pseudo-static stability analyses of permanent spoil heights; selective-handling specifications and spontaneous-combustion mitigation.
- Reclamation/postmining stability - Long-term stability of the AOC landform under static and seismic loading, with allowance for settlement

**13.1.2** **Hydrogeological Model**

The hydrogeological model for the Brook Mine is anchored on a network of dedicated groundwater monitoring wells installed by WWC and its predecessors between 2013 and 2019. The baseline network was established in September and October 2013 with eighteen wells distributed across Sections 8, 9, 10, 11, 12, 13, 15, 17, and 18 of Township 57N Range 84W and Range 85W (Sheridan County, Wyoming), targeting the Carney Seam, the Masters Seam, the Masters underburden, and the Tongue River alluvium. The network was supplemented in 2014 and 2015 (well 578421-3-MAS and three Tongue River alluvial wells), again in May and June 2018 (Big Horn Coal spoil wells 578415-SPL-1/-2, overburden well 578513-OVB-1, paired alluvial/Carney pump-test wells 578420-AL-1/578420-CRN-PUMP and 578524-AL-1/578524-CRN-PUMP), and in July 2019 (downgradient alluvial well 578415-AL-1). Wells are 2-inch and 5-inch diameter, completed with factory-slotted PVC screen, hydrated bentonite-chip annular seals, and in piezometers installed in core-hole clusters R13-012 and R13-018, an 8/12 silica sand filter pack. Construction follows Wyoming Department of Environmental Quality (WDEQ) Land Quality Division guidelines.

Four constant-rate pumping tests have been conducted on the site to date. Single-well slug (rising- and falling-head) tests were performed on the majority of the monitoring wells, and water levels have been measured quarterly across the network since fall 2013, with continuous coverage at the 578409 cluster and most other locations through 2018-2019.

The wells, tests, and monitoring data together support a three-unit hydrostratigraphic conceptualization within the mine footprint: (i) a discontinuous Tongue River and Slater Creek alluvium that is the principal shallow aquifer; (ii) the Carney and Masters coal seams within the Tongue River Member of the Fort Union Formation, which are the only laterally continuous bedrock aquifers above 1,000 feet depth and which behave as confined to semi-confined units separated by approximately 20 to 60 feet of low-permeability claystone interburden; and (iii)

​

a mostly dry overburden and a generally dry Masters Seam underburden (the latter producing measurable water in only one tested well, 578409-UBN). The Carney Seam potentiometric surface lies approximately 100 to 150 feet below the alluvial water table across the eastern portion of the permit area, and the two 2018 pump tests demonstrate no measurable hydraulic communication between the coal and the alluvium across the intervening claystone. Recharge is interpreted to occur principally through clinker (scoria) outcrops and at the limited western coal subcrops; flow is southeast, down-dip into the greater Powder River Basin.

The well network and test program described above were designed to support the permitted trench/HWM layout, in which excavation depth is limited and the Masters Seam underburden and deeper claystone aquitards are not routinely exposed. The planned conversion to a truck-and-shovel surface mining method increases pit depth and pit-wall length per unit time and thereby alters the hydrogeologic exposure in three respects that the existing dataset addresses only partially, detailed as follows:

The program characterizes the Carney and Masters seams but provides only a single completed well in the Masters underburden (578409-UBN); a truck-and-shovel pit that routinely floors below the Masters Seam will require additional underburden characterization to confirm the regional interpretation that this unit is dry to low-yielding.

The existing tests confirm that the 100 to 150 ft of claystone separating the Carney from the Tongue River alluvium is an effective aquitard under the current pit geometry; a deeper truck-and-shovel pit advancing toward the western Carney subcrops will progressively shorten that pathway and warrants pit-specific re-evaluation.

Slug-test failures at the Big Horn Coal Pits 1-3 spoils indicate that any portion of the Brook Mine pit that intersects legacy spoils will encounter materials with very high hydraulic conductivity and direct continuity with the Tongue River/Goose Creek alluvial system.

WEIR recommends Ramaco complete detailed hydrogeological characterization for revised Brook Mine pit walls, including piezometer nests in the proposed final pit walls, packer/slug-test characterization of the coal-aquifer/sandstone-aquifer hydraulic conductivities, and a pit-inflow/depressurization model coupled to the slope-stability analyses.

**13.2** **Production Mine Life, Dimensions, Recovery, and Dilution**

The truck-and-shovel method planned for the Brook Mine effectively accommodates the multi-seam stratigraphic section (the Dietz, Monarch, Carney, Masters and Low Seams), provides flexible access to the full coal-bearing column for TCM processing, achieves higher overall coal recovery, and matches the productivity required to maintain a steady Run-of-Mine (ROM) feed to the planned TCM process plant.

To support the Brook Mine Resource estimate, WEIR has developed a conceptual LOM Plan production schedule covering a subset of the Mineral Resources extending from west to east. WEIR utilized the revenue factor 0.68 pit shell developed as part of the pit optimization process described in Section 11.2. This pit shell was chosen to provide approximately 40 years of mining at the total production capacity of the planned fleet as described in this section.

The LOM Plan schedule is a year-by-year balance of material mined, coal recovered for sale, TCM resources mined, TCM resources direct-to-plant feed, higher-grade (HG) and lower-grade (LG) TCM resource stockpile movements, and the associated head grades of the seven TCM elements that meet the threshold of reasonable prospects for economic extraction (Dy, Ga, Ge, Nd, Pr, Sc, and Tb). The LOM Plan is sized to deliver a constant TCM mill feed to the planned process plant and to recover the in-situ coal resource on a schedule consistent with surface mining equipment productivity and pit advance rates. The LOM Plan serves as the quantitative basis for the production, mine life, recovery, and dilution discussion that follows.

**13.2.1** **Production Rates**

The conceptual LOM Plan is governed by a steady-state TCM resource plant feed of approximately 2.63 million tonnes per annum (Mtpa). To support that plant feed and to recover the associated coal resources, the operation moves an average of approximately 27.2 Mtpa of total material, comprising approximately 18.8 Mtpa of waste (non-mineralized overburden, parting, and interburden), approximately 7.3 Mtpa of TCM resources (plant feed), and approximately 1.1 Mtpa of in-situ coal resources. Depending on the grade, the TCM resources mined are routed to direct plant feed, the HG stockpile, or the LG stockpile. In-situ coal resources are processed to a saleable thermal coal product averaging approximately 1.0 Mtpa over the LOM. Annual coal production varies materially across the schedule (approximately 0.0 to 3.2 Mtpa as recovered coal sold, and 0.0 to 3.5 Mtpa as in-situ coal mined) because coal resource availability is a function of seam intersection within the strip-by-strip pit advance, while TCM plant feed is held constant by drawing from the HG and LG stockpiles when in-pit

​

​ ​

July 24, 2026 Page 104

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

TCM mined in a given year is below plant capacity. Total material movement is held to a narrow band of approximately 27.2 Mtpa throughout the schedule, reflecting the design productivity of the truck-and-shovel fleet defined in Table 13-5.

**13.2.2** **Expected Mine Life**

The conceptual LOM Plan extends over 40 years of full-scale production, during which approximately 1.09 billion tonnes of total material is moved, approximately 293 million tonnes of TCM resources are mined, and approximately 105.2 million tonnes of TCM resources are delivered to the process plant as plant feed. The in-situ coal resource within the LOM Plan footprint totals approximately 45.4 million tonnes, of which approximately 40.8 million tonnes is recovered as saleable coal product over the 40-year schedule. The LOM Plan is focused on recovering high grade TCM resources to improve project economics and extracts nearly three times the required TCM resource over the course of the LOM. The lower grade TCM resource is stockpiled in segregated areas within mined out portions of the pit for later processing.

The 40-year LOM Plan is based on the revenue factor 0.68 pit shell targeting approximately 1.1 billion tonnes of total material, and the planned process plant capacity rather than by any single-pit geometric limit. Mining begins in the northwest portion of the LOM Plan pit and progresses eastward over the 40-year duration of mining. Closing stockpile balances at the end of the 40-year LOM Plan are approximately 10.8 million tonnes of HG TCM resource and approximately 177 million tonnes of LG TCM resource; the disposition and post-Year-40 processing potential of the residual HG and LG stockpiles are not included in the current LOM Plan schedule and are identified as a future planning item. It is anticipated that the stockpiled TCM resource will be placed in mined-out areas and shaped to conform with potential reclamation requirements in the event that the stockpiled TCM resources are not reclaimed and processed. Stockpiled TCM resources will be segregated from waste material in the mined-out areas. TCM resources remaining in stockpiles at the end of the 40-year LOM Plan do not contribute revenue in the economic analysis described in Section 19.

**13.2.3** **Mine Design Dimensions**

The mine will be developed as a series of nested pit phases developing from the northwest to the south and then advancing towards the eastern extent of the resource area. Pre-mining surface elevations across the LOM Plan pit area range from approximately 3,630 to 4,080 feet above mean sea level, the lowest area of the LOM Plan pit lies near elevation 3,410 feet, the

​

​ ​

​

maximum pit depth is on the order of 490 feet at the deepest point. Final highwalls range from 60 to 400 feet in height depending on the location and overlying topography.

The conceptual truck-and-shovel design replaces the 150-foot wide trench-floor geometry and 65-degree single-bench highwall of the permitted plan with a benched, multi-lift open-pit configuration that uses overburden working benches on the order of 40 to 60 feet in height, individual bench-face angles of approximately 65 to 70 degrees, an overall highwall slope angle of approximately 40 to 45 degrees, pending final geotechnical confirmation, in-pit haul ramps constructed at sustained grades of 8 to 10 percent on a minimum running width sized for two-way haul truck travel, and spoil placement at the angle of repose (nominally 37 degrees) with a 16-percent material swell factor. Cross-pit and out-of-pit spoiling will be used as dictated by haul distance and reclamation contour requirements. Final pit geometry, bench widths, slope angles, and spoil-dump geometry will be confirmed through site-specific slope-stability analyses as part of the permit revision.

**13.2.4** **Mining Recovery and Dilution**

The conceptual LOM Plan applies a coal mining recovery factor of approximately 90 percent, reflecting typical industry performance for PRB truck-and-shovel operations with drill-and-blast preparation of the coal seams and selective end loader- and excavator-cleaning of the roof and floor to limit out-of-seam contamination. The 90-percent recovery factor is consistent with the surface-mining recovery cited in the currently permitted plan. TCM resources within five feet of the roof and floor of the coal seam are recovered using front-end loaders and hydraulic excavators and routed to the TCM process plant feed or to HG/LG stockpile based on the block-by-block grade in the geologic model. Mining dilution is captured in the LOM Plan based on the inherent dilution incorporated within the geologic block model through the aggregation of blocks within the block model to the mineable horizons. No external dilution has been applied at this stage. Material reporting to process plant feed therefore reflects the weighted average grade of the mineralized horizons. The LOM Plan average TCM metal head grades delivered to the plant are approximately 48.3 g/t Nd, 23.4 g/t Ga, 21.1 g/t Sc, 12.3 g/t Pr, 7.5 g/t Dy, 3.6 g/t Ge, and 1.3 g/t Tb. These plant-feed grades are the basis for the economic analysis presented in Section 19. The waste-to-coal strip ratio over the LOM Plan averages approximately 18.4 tonnes of waste per tonne of recovered coal; on a combined coal-plus-TCM product basis the LOM strip ratio averages approximately 2.2 tonnes of waste per tonne of mineralized product mined. These recovery, dilution, and mining limits carry forward into the economic model in Section 19 and will be refined as the geologic block model, the pit-optimization shell, and the geotechnical slope design are advanced in the next phase of mine planning.

**13.2.5** **Life of Mine Plan**

Based on the mine design and production parameters discussed previously, a LOM Plan was developed that produces the mining and TCM process plant feed schedules and head grade summary shown in Table 13-3 and an overall summary of the conceptual LOM Plan is shown in Table 13-4.

**Table 13-3****Conceptual LOM Plan Schedule**

​

**Table 13-4****Conceptual LOM Plan Summary**

**13.3** **Development Requirements**

As appropriate for an Initial Assessment, the development requirements for the Brook Mine are conceptual in nature. Based on the geology of the deposit, TCM resources and coal resources are present at relatively shallow depths requiring minimal stripping of waste. As such, no pre-production waste stripping has been planned.

The Brook Mine currently has primitive access roads available across much of the resource area allowing initial access to the mining areas, however, these primitive access roads will need to be upgraded to accommodate large mining equipment. Additionally, surface water control structures will need to be constructed in a similar manner to those currently approved in Ramaco’s WDEQ and WPDES permits. Permit modifications will be necessary to accommodate the revised mining method and mine plan.

​

​ ​

July 24, 2026 Page 108

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Mine support facilities will need to be constructed as well consisting primarily of a mine office, mobile equipment maintenance facilities, fuel storage and dispensing stations, warehouse and storage facilities for maintenance spares and supplies and mine employee bathhouse.

It is anticipated that these pre-production development activities will require 12 to 24 months to design and construct prior to commencement of mining activities.

**13.4** **Mining Equipment and Personnel**

**13.4.1** **Mining Equipment**

The removal of overburden, TCM resources, and coal resources will be conducted utilizing surface mining equipment. The planned Brook Mine is projected to use the following surface mining equipment as shown in Table 13-5.

**Table 13-5****Brook Mine Equipment List**

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**13.4.2** **Staffing**

The Brook Mine is planned to produce coal and TCM resource during two production shifts each day, with three rotating crews working 12-hour shifts per day, seven days a week, 365 days a year. Table 13-6 indicates anticipated staffing requirements after mine startup.

**Table 13-6****Brook Mine Staffing**

As of December 31, 2025, there were 10 people employed at the iCAM facility. Recruiting suitable personnel to operate the mine and process plant may prove to be a challenge for Ramaco. The Brook Mine is close to Sheridan, Wyoming, with a 2025 population of approximately 20,000. There are also other smaller towns surrounding the Brook Mine. As such, the availability of experienced new hires may be limited. Some experienced personnel may be available from Gillette, Wyoming (110 miles southeast) which, over the last few years, has experienced mining personnel reductions.

**13.5** **Life of Mine Plan Map**

WEIR produced a conceptual LOM Plan sequencing a logical mining progression through a subset of the Brook Mine Resource Area. The extent of the conceptual LOM Plan is shown on Figure 13-1. Cross sections through the LOM Plan pit shell and resource pit shell along with NSR of the TCM resources are shown on Figure 13-2.

**14.0** **Processing and Recovery Methods**

A multi-stage leaching process produces high extraction efficiencies from the TCM plant feed. The flowsheet design was supported by preliminary metallurgical testing conducted by Hazen. TCM process plant feed grades were generated from the LOM Plan completed by WEIR.

The processing method and plant design used in this flow sheet are similar to what is commercially being used elsewhere, with some modifications to address specific mineral characteristics of the TCM mineralization at the Brook Mine. The pre-treatment method and the reagents and operating conditions for the multi-stage leach is considered Ramaco intellectual property and has not been disclosed. Therefore, detailed descriptions of the flowsheet and equipment are not publicly disclosed. The QP has reviewed these documents and supports the process designs, costs and recoveries used in the Initial Assessment.

The mine and process plant requires a total headcount of 190 personnel, encompassing the mine (70), mineral processing (100), and general and administration (20) functions.

**14.1** **Material Handling Process and Flowsheet**

The rare earth and critical minerals extraction process at the planned Brook Mine involves several sequential steps to extract TCMs from the run-of-mine (ROM) material. In their preliminary form, these steps are detailed as follows:

1. Feed Handling and Comminution - The ROM material, which has high crushability and a low Crushing and Grinding Work Index, is processed. Mineral sizers are used as primary and secondary size reduction to handle the high clay and moisture content material. An open circuit ball mill is used to achieve a target p80 of 200 µm for the leach feed.

2. Pretreatment - The ball mill discharge, primarily composed of kaolinite clay and quartz with minor iron oxides and coal, undergoes a pretreatment step that aims to assist liberation of critical minerals and enhance leach kinetics for subsequent steps.

3. Primary Leaching and Filtration - A primary leaching agent is applied to pretreated feed to solubilize the host mineral matrix, liberating gallium and germanium, and also attacking a portion of the liberated REEs. The resulting slurry is then filtered, with the residue containing most of the REE content sent for secondary leaching.

​

​ ​

July 24, 2026 Page 113

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

4. Secondary Leaching and Filtration - The filter cake from the primary leach is re-pulped and treated with a secondary leaching agent to solubilize the remaining REEs. Some gangue minerals are also leached during this reaction. The impure REE solution is filtered, producing a PLS Filtrate and a final leach residue, which is washed and discarded as cake to a lined dry stack storage area.

5. Impurity Removal - Precipitation and Ion Exchange:

a. Impurity Precipitation: The impure REE solution is transferred to purification reactors where some impurities are removed by pH adjustment, leading to their precipitation. This constitutes the first stage of purification, yielding a partially purified REE filtrate for the Solvent Extraction (SX) circuit. The filter cake from this stage is combined with the leach residue and sent to the residue storage area.

b. Ion Exchange (IX): Other contaminants in the filtrate from the impurity precipitation stage are removed using an ion exchange process. Specific resins absorb these impurities, allowing REE ions to pass through to the SX circuit. Loaded resin is then stripped, with the effluent enriched in impurities sent to waste treatment.

6. Rare Earth Separation - Solvent Extraction: After IX, the REEs, now free from impurities, are still dilute. They are re-precipitated by adjusting the pH, forming a concentrated REE precipitate including Scandium, which is filtered out. This filter cake is then re-leached in hydrochloric acid to feed the SX with a high REE chloride solution. The exact number of contact mixer settlers for the SX circuit will be determined based on future metallurgical testwork.

7. Gallium & Germanium Processing - Gallium and germanium are selectively removed from the REE metals during the filtration step in the Primary Leach Section. Gallium is recovered using the industry-established SX with Kelex 100, which offers high selectivity. Both gallium and germanium are recovered in hydroxide form and then calcined, potentially using the REE calcining systems with measures to avoid cross-contamination.

A high-level block flow diagram of the proposed processing steps is provided on Figure 14-1, as follows:

​

**Figure 14-1****Block Flow Diagram**

**14.2** **Production**

The Brook Mine TCM process plant is designed with a ROM throughput of 2.6 million tonnes per year. Annual average production of the TCMs is summarized in Table 14-1, as follows:

**Table 14-1****Targeted Critical Mineral Oxide Production**

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Other critical mineral oxides are not separated into final products and thus, have not been assigned any value in this flowsheet.

**14.3** **Utilities**

**14.3.1** **Power Requirements**

Power consumption of 9.3 MW is estimated from the mechanical equipment list, based on equipment run times and absorbed power.

All process electrical rooms are modular units assembled offsite. The rooms are installed outdoors on elevated steel structures adjacent to process areas or indoors on elevated structures. The rooms are self-supporting, designed and packaged for road shipment to site. All electrical controls and instrumentation equipment are installed, wired, and completely tested before shipment.

The rooms are built to meet a one-hour fire rating. All openings are sealed and made water- and dust-tight by using approved fire-retardant materials.

All electrical rooms have two means of egress at opposite ends of the room. Doors to the rooms are supplied with panic exit type hardware. Each room also has an equipment door sized to permit the largest piece of equipment to be installed/removed without removing the door from its hinges. The floors of the rooms will be elevated a minimum of 20 cm (8 inches) above the adjacent concrete floors in the process plant.

The electrical rooms are pressurized, air conditioned, and designed in accordance with occupancy regulations.

**14.3.2** **Water Supply**

Fresh water is supplied by drilled wells on site. The wells supply the site’s domestic and firewater needs, as well as the process make-up water. Total makeup water is estimated to be about 0.6 tonnes per tonne of mill feed. Water uses in the plant include the following:

​

**15.0** **Infrastructure**

**15.1** **Roads**

Access to the property is from Interstate Highway 90, which crosses the property from west to south. State Highway 338, which connects Sheridan, Wyoming to Decker, Montana, crosses the southeastern portion of the Brook Mine. Secondary roads and trails provide access to the remaining lands.

The nearest airport is the Sheridan County Airport (SHR), which is located in Sheridan, Wyoming, approximately seven miles southeast of the Brook Mine. The Billings Logan International Airport (BIL) in Billings, Montana, is located approximately 95 miles northwest of the Brook Mine.

**15.2** **Rail**

Rail access is by the Burlington Northern Santa Fe Railroad, which is located in the Tongue River and Goose Creek valleys. This rail access is centrally located adjacent to the south side of the permit area.

A rail spur is planned for the project and included in the capital estimate. It is used to receive construction materials. During operations, bulk reagents are brought into the site and thermal coal are moved by rail to customers.

A conceptual assessment was performed for delivery, receiving, unloading and storage of major reagents to be used in Brook Mine TCM process plant. With the Sheridan rail facility available only several miles south of the selected project site, the following options are available for the major reagents’ delivery.

- Delivery of reagents via truck to the process facility.
- Delivery of reagents via rail car to the process facility.
- Delivery of reagents via rail car at Sheridan and transported via trucks to the process facility.

A total monthly reagent consumption of about 47,300 tonnes will be delivered by rail car while about 60 tonnes a month are delivered by truck. The total on-site storage capacity for the various reagents varies from 7 to 28 days.

​

​ ​

July 24, 2026 Page 121

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

From the assessment, delivery of reagents via rail car at Sheridan and transporting via trucks to the process facility for delivery, unloading and storage is the most viable and recommended option with Sheridan rail network facility is readily available for use.

**15.3** **Power Supply**

Ramaco currently purchases electricity from MDU for its surface facilities. Services from MDU are currently being upgraded for electrical supply to the pilot process plant. This will require further expansion for commercial operations. Site power consumption is estimated to be about 9.3 MW. Power consumption was estimated from anticipated loads.

Grid power supply ties into a main substation at the plant site. To minimize installation costs, electrical rooms are distributed around the site and installed as close as possible to the major electrical loads.

**15.4** **Water**

Fresh water will be supplied by drilled wells on site. The line will supply the site’s domestic and firewater needs, as well as the process make-up water. Water derived from sources of groundwater will be integrated into the water supply and distribution system using pipelines to provide water to the site needs (i.e, make-up process water, dust control, fire suppression, potable needs). Details on site specific water use are described in Section 14.

**15.5** **Pipelines**

Oil and gas pipelines are common occurrences at the Brook Mine. Owners will be contacted in situations that involve potential disturbance of existing wells and pipelines. In general, no mining is anticipated within accepted exclusion zone as determined by regulators from any existing oil and gas pipelines and wells.

**15.6** **Waste Management**

Leached residue after secondary leaching is washed, filtered and trucked to the dry stack tailings area. It is assumed for the study that these areas are lined. The cost to expand the lined facility is included in the process plant operating costs. Since the coal will be sold as a direct shipped thermal product, no coal processing will be required and thus, no coal refuse disposal will be required.

​

​ ​

July 24, 2026 Page 122

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Other waste generated during operations include lubricants, diesel fuel, oil, oily water, containers and drums, sewage, solid waste, chemicals, discarded general waste, and medical waste. A detailed project waste management plan will be developed in the next phase of the project, once quantities and types of waste are defined.

Any soil and other unconsolidated earthen material that become impacted by releases of various types of standard hydrocarbons (i.e., fuels, motor oil, etc.) because of unplanned releases and/or accidents will be transported to an appropriately licensed facility or otherwise remediated in an appropriate manner, as authorized by WDEQ, and directed through implementation of a management plan.

The expected minimal amount of hazardous and medical waste resulting from operations will be containerized and transported in accordance with the project waste management plan. These materials will be sent to an appropriate disposal or recycling site, operated in accordance with Wyoming state requirements.

Sewage waste streams originate as effluent from bathroom facilities and breakroom operations and are managed through a contracted package sewage plant. Effluent from the treatment plants is monitored to verify the treatment systems are functioning as designed and meet applicable environmental design criteria.

A packaged sanitary wastewater treatment system is provided to treat waste from restrooms, break rooms, and other potable water users onsite. The water is treated with membrane bioreactor technology. Treated effluent is taken offsite and disposed of at an appropriate waste facility.

**15.7** **Fuel Supply**

Fuel needed to support operations at the project site is transported by a contracted third-party using delivery trucks to supply fuel to a fuel station at site. This fuel station will include:

- Unloading pumps
- Fuel storage tanks
- Vehicle fuel dispensing pumps and bowsers
- Concrete pads for fuel loading and unloading
- In-ground containment system with low-point sump for inspections and extraction

​

​ ​

July 24, 2026 Page 123

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The fueling facility will be located near the maintenance and wash facilities and consists of above-ground tanks with unloading pumps for both diesel and gasoline. The facility is located on concrete pads. The tanks will be equipped with overspill protection valves and alarms and tanks are double walled.

The entire fuel storage area (including vehicle drive-up and fueling areas) is located within an in-ground containment system that utilizes HDPE lining and a low-point sump. This containment area is sized to capture the volume plus 10 percent of the largest tank in the fuel station. Any water that enters the containment will go to a low-point sump. Water is tested and, if contaminated, disposed of in accordance with, local, state and federal guidelines.

A spill prevention, control, and response plan will guide the management of fuel used onsite and emergency response procedures in the event of an accidental release of fuel to the environment, as well as define necessary worker training programs to be developed and implemented onsite.

Natural gas is used for process and building heating. A tie in will be brought to the site boundary. An estimated annual consumption of about 900,000 GJ is required for the site.

**15.8** **Map of Infrastructure**

Existing structures on the site are currently limited to the iCAM building as shown on Figure 15-1, along with other features such as rail, oil and gas wells, and power lines. Proposed site facilities including the TCM process plant, initial residue storage location and initial waste dumps and TCM stockpiles were shown previously on Figure 13-1. The TCM process plant and initial residue storage locations are generally North-Northwest of the Taylor Quarry on Ramaco owned surface land.

**16.0** **Market Studies**

Ramaco developed a long-term pricing model for the Brook Mine’s TCM products based on western market prices as of December 31, 2025, consistent with Ramaco’s fiscal year-end. Prices reflect the structural bifurcation between Chinese domestic benchmark prices and ex-China western market prices that has developed as a result of Chinese export controls and supply chain fragmentation. Chinese domestic prices are not considered representative of the market accessible to a North American producer and have not been used in this study. No material contracts have been signed to develop the project.

Brook Mine anticipates production of seven revenue-generating separated rare earth and critical mineral oxides, also referred to as TCMs. The anticipated product form, annual production tonnage, prices used in the financial model, and revenue contribution for each are summarized in Table 16-1. Pricing used for the Resource pit shell in Section 11 was based on early 2025 pricing while updated pricing as of the end of 2025 is described within this section. Long-term pricing is held constant over the 40-year LOM and does not include the approximate $18.4 million annual average revenue generated from coal sales. Demand and pricing for each TCM product are discussed in detail in Sections 16.1 through 16.5.

**Table 16-1****TCM Product Pricing and Specifications**

​

​ ​

July 24, 2026 Page 126

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The average basket price for all revenue-generating products, weighted by percent of production, is $1,145 per kg of oxide equivalent.

TCM Pricing assumptions used in this study are supported by the following:

- Published spot market prices on recognized western commodity price indices as of December 31, 2025, as detailed in Sections 16.1 through 16.5.
- Recent third-party independent market studies available in the public domain, as identified and cited in Sections 16.1 through 16.5 and listed in Section 24.

Western prices are used rather than Chinese domestic benchmark prices, which are not representative of the market accessible to a North American producer. The divergence between Chinese domestic and western prices reflects structural supply chain fragmentation rather than temporary market conditions, and is expected to persist through the Brook Mine’s anticipated production horizon.

Thermal coal will be produced as part of the mining process for TCMs. It is expected to be sold primarily into the domestic thermal coal markets served by several existing mines in the area. Anticipated FOB Mine sales price is $16.53/tonne of coal. This is consistent with current and forecast pricing for coals of similar quality and based on PRB coal indices as published by McCloskey as of December 2025.

The QP relied on information supplied by the Registrant’s commercial and marketing personnel regarding product sales, customer demand, transportation logistics, and pricing assumptions. The QP reviewed the information for consistency with published market data, and industry practice and considers such reliance reasonable.

**16.1** **Scandium**

**16.1.1** **Scandium Demand and Supply**

There are currently no primary scandium mines in production globally. Scandium is produced almost exclusively as a byproduct of other metal refining operations, principally titanium dioxide pigment processing, nickel laterite high-pressure acid leaching (HPAL), and alumina refining, with active production concentrated in China, the Philippines, Canada and Russia (USGS).

​

​ ​

July 24, 2026 Page 127

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Published market estimates commonly cite global scandium oxide consumption at 30 to 40 tonnes per year. However, Ramaco’s internal analysis indicates this figure materially understates actual demand because Bloom Energy’s solid oxide fuel cell (SOFC)-related consumption is systematically excluded from conventional trade statistics due to alternate import classification codes. When Bloom Energy’s consumption is properly accounted for, Ramaco estimates true global scandium oxide consumption at approximately 55 to 65 tonnes per year as of 2024 (Ramaco Internal, Bloom Energy).

The three principal demand sectors for scandium oxide are aluminum-scandium (Al-Sc) alloys for aerospace and defense applications, solid oxide fuel cells (SOFCs), and semiconductor electronics. Each is discussed below (Ernst & Young LLP, Ramaco Internal).

16.1.1.1 Solid Oxide Fuel Cells

Scandium-stabilized zirconia (ScSZ) is the preferred electrolyte material for solid oxide fuel cells, enabling operating temperatures of 700 to 800°C with superior ionic conductivity and extended stack service life relative to yttria-stabilized alternatives. Bloom Energy is the dominant global consumer of scandium oxide, using it as the electrolyte in its Energy Server SOFC systems.

Bloom Energy’s 10-K filing for fiscal year 2023 reports 268 MW of customer acceptances, equivalent to 2,682 units of its 100 kW module. Using the industry-standard loading of 13 to 15 kg of Sc₂O₃ per 100 kW module, as documented in peer-reviewed literature and consistent with commercial stack power density ratings of ≤150 mW/cm², Bloom’s consumption calculates to approximately 40 to 44 tonnes of Sc₂O₃ per year, inclusive of fabrication yield losses and spare stack requirements of approximately 10 percent (Bloom, Ramaco Internal, Phoung).

This single company therefore accounts for approximately 70 to 75 percent of estimated global scandium oxide consumption. Bloom Energy has provided guidance indicating significant growth in future SOFC demand, with Ramaco’s internal analysis projecting Bloom’s consumption growing at a 15 percent CAGR to approximately 98 tonnes per year by 2030, based on publicly disclosed capacity expansion plans. Rest-of-world SOFC demand is estimated at 12 to 15 tonnes per year currently, growing at a 3 percent CAGR at least (Ramaco Internal).

​

16.1.1.2 Aerospace and Defense - Aluminum-Scandium Alloys

The addition of small quantities of scandium (typically 0.1 to 0.5 percent by weight) to aluminum produces alloys with substantially improved mechanical properties, including tensile strength increases of 30 to 100 percent, significantly enhanced fatigue resistance, improved weldability, and superior resistance to corrosion and thermal stress. These properties are highly valued in commercial aviation, defense aerospace, additive manufacturing, and hypersonic applications (Ernst & Young LLP).

Boeing’s Commercial Market Outlook 2025-2044 forecasts demand for approximately 44,000 new commercial aircraft over the forecast period. The Airbus Global Market Forecast 2025-2044 similarly projects the global passenger and freighter fleet nearly doubling from approximately 24,700 aircraft at end-2024 to approximately 49,200 by 2044, requiring approximately 43,400 new deliveries. At a 0.5 percent Al-Sc alloy incorporation rate applied to lightweighting programs, Ramaco’s internal analysis estimates annual commercial aviation demand of 400-750 tonnes per year of scandium oxide by the mid-2030s, consistent with the Ernst & Young (2022) demand trajectory (Boeing, Airbus, Ramaco Internal Airlines, Ernst & Yount LLP).

The Ernst & Young (2022) study projects aerospace and defense sector scandium demand growing from approximately 2 tonnes per year at study inception to 245 tonnes per year over a 20-year period, based on progressive adoption of Al-Sc alloys across airframe structures.

Defense demand is an emerging near-term driver. The United States Defense Logistics Agency’s SBIR Topic DLA242-003 explicitly calls for scaling Al-Sc supply chains for missiles, aircraft, space launch vehicles, and other weapon systems, a strong signal that the Department of Defense anticipates domestic scandium supply and is prepared to fund qualification programs. NioCorp Developments Ltd. has entered agreements with United States defense primes to supply qualified Al-Sc alloy components under the Defense Production Act, further substantiating near-term defense sector pull (NioCorp).

Ramaco’s internal analysis estimates current United States DoD scandium consumption at approximately 2 to 5 tonnes per year, growing to a range of 7 to 15 tonnes per year by 2030 driven by additive manufactured Al-Sc components across Navy airframes and submarines, hypersonic and missile skin applications, and F-35 and B-21 block upgrade programs (Ramaco Internal).

16.1.1.3 Scandium Supply Constraints and Western Market Access

In April 2025, China imposed export controls on scandium under MOFCOM/GAC Announcement No. 18/2025, classifying it as a dual-use military material and requiring case-by-case export licensing for all forms including metal, oxide, alloys, and compounds. China controls approximately 60 percent of global scandium supply, with over 90 percent of total supply (including Russia) coming from jurisdictions that are either subject to export restrictions or considered strategically unreliable by western governments (Ramaco Internal, USGS).

Ramaco’s internal supply analysis estimates total committed western supply expansions through 2027, including Rio Tinto’s ramp at Sorel-Tracy, Quebec to approximately 12 tonnes per year, could bring total global nameplate capacity to only approximately 120 tonnes per year by 2027. Against Ramaco’s projected global demand of 60 tonnes per year over the life of mine, this leaves some margin for new aerospace and Al-Sc adoption even in a conservative demand scenario, and significantly underserves SOFC demand growth (Ramaco Internal).

Development-stage western projects that could contribute supply beyond 2027 include Sunrise Energy Metals’ Syerston Project in New South Wales, Australia (approximately 60 tonnes per year, feasibility study Q3 2025, earliest production approximately 2028), NioCorp’s Elk Creek Project in Nebraska (approximately 55 tonnes per year, feasibility stage), and Scandium Canada’s Crater Lake Project in Quebec (approximately 40-50 tonnes per year, PEA completed 2022, updated Mineral Resource April 2025). (Scandium Canada, Niocorp, Sunrise Energy).

As of the report date, western scandium supply is acutely constrained and no near-term resolution is apparent. Brook Mine’s anticipated scandium oxide production of approximately 60 tonnes per year would represent a material and strategically significant contribution to western supply at a time when demand from SOFC, aerospace, and defense applications is growing rapidly and Chinese supply access has been formally restricted.

The EY (2022) market analysis projects unconstrained total global scandium oxide demand reaching 463 tonnes per year by 2030 and 1,970 tonnes per year by 2040 under the most likely scenario, across aerospace and defense, automotive, solid oxide fuel cells, and offshore wind turbine sectors. This latent demand substantially exceeds currently available supply, confirming that market growth is supply-constrained rather than demand-constrained over the near to medium term (Ernst & Young LLP).

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

However, given that global scandium supply is projected at only approximately 120 tonnes per year by 2027 even with committed western expansions, actual realized demand is expected to remain materially below EY’s unconstrained forecast in the near term. Under a supply-constrained scenario, total global scandium oxide demand is projected to grow from approximately 55 to 65 tonnes per year in 2024 to approximately 127 tonnes per year by 2030, at a compound annual growth rate of approximately 12 percent, driven principally by SOFC capacity expansion and progressive adoption of Al-Sc alloys in aerospace and defense.

The global Supply and Demand forecast for Scandium Oxide is presented in Table 16-2.

**Table 16-2****Scandium Oxide: Global Long-Term Supply and Demand Forecast**

Notes:

1. EY (2022) projects unconstrained global scandium oxide demand reaching 463 t/yr by 2030 and 1,970 t/yr by 2040 across aerospace and defense, automotive, solid oxide fuel cells, and offshore wind turbine sectors. Current global consumption is estimated at 55 to 65 t/yr, reflecting supply constraints rather than demand limitations. Latent demand substantially exceeds available supply across all major end-use sectors. As new primary supply sources including Brook Mine come online through the forecast period, realized demand is expected to progressively approach the EY market potential trajectory. (EY, Scandium Market Analysis, February 2022; Ramaco internal demand analysis, September 2025)

2. Current global scandium oxide production is estimated at 55 t/yr. Committed western supply expansions including Rio Tinto’s ramp at Sorel-Tracy, Quebec to approximately 12 t/yr could bring total global nameplate capacity to approximately 120 t/yr by 2027. Western supply expansion beyond 2027 is speculative given no large-scale primary scandium projects have reached construction decision as of the report date. The 250 t/yr figure for 2036 to 2045 represents a conservative estimate assuming advancement of Sunrise Energy Metals’ Syerston Project and NioCorp’s Elk Creek Project. (USGS Mineral Commodity Summaries 2025; Ramaco internal supply analysis, September 2025)

3. Beyond 2040, demand is held flat at the EY 2040 forecast level of 1,970 t/yr as no credible long-term forecast is available.

**16.1.2** **Scandium Pricing**

There is no established public exchange or index for scandium oxide pricing equivalent to those available for base metals or other rare earth elements. Prices are determined through bilateral negotiation and are sensitive to purity, quantity, and the terms of supply agreements. Published market data and government procurement records provide the principal basis for price estimation.

Historical scandium oxide prices (99.99 percent purity) ranged from approximately $3,800 to $5,000 per kilogram from 2013 to 2020, as reported in successive USGS Mineral Commodity Summaries. Published market analysis for 2024 indicates prices in the range of $3,000 to $4,500 per kilogram for 99.99 percent purity material, reflecting the constrained supply environment and the absence of large-scale western production (Phoung, USGS 2017, 24chemical).

The most significant publicly documented western market transaction is the United States Defense Logistics Agency’s procurement of scandium oxide from Rio Tinto’s Canadian operations, under a contract valued at up to $40 million for approximately 6.4 metric tonnes over five years, implying a contract price of approximately $6,250 per kilogram. This transaction represents the clearest available evidence of western government procurement pricing for high-purity scandium oxide and establishes a meaningful upper bound for the western market (Reuters).

A scandium oxide price of $3,750 per kilogram has been used in this study, representing the midpoint of the 2024 published market range for 99.99 percent purity material and a 40 percent discount to the DLA government procurement price. This price is considered conservative relative to observable western market conditions as of the report date, particularly given the supply disruption resulting from China’s April 2025 export controls, which post-date the original project economics but were implemented prior to the report date and are expected to exert sustained upward pressure on western prices through the project’s anticipated production horizon.

All prices are stated in United States dollars per kilogram of scandium oxide (Sc₂O₃) at 99.99 percent purity, consistent with the product specification anticipated from the Brook Mine processing flowsheet.

**16.2** **Gallium**

**16.2.1** **Gallium Demand and Supply**

Gallium is recovered almost exclusively as a byproduct of processing bauxite ore for alumina production and, to a lesser extent, from zinc smelting residues. There is no primary gallium mine anywhere in the world. China accounts for 99 percent of worldwide primary low-purity gallium production, with a 2024 estimated output of approximately 750,000 kilograms (750 tonnes) against a total global primary production capacity of approximately 1,100 tonnes per year. The remaining primary producers outside China are Japan, the Republic of Korea, and Russia, whose combined output totals approximately 12,000 kilograms per year. The United States has not recovered domestic primary gallium since 1987 and is 100 percent import-reliant for its gallium supply, as reported by the USGS.

World high-purity refined gallium production in 2024 was estimated at approximately 320 tonnes, unchanged from 2023, against a total refined capacity of approximately 340 tonnes per year. The principal producers of high-purity refined gallium are China, Canada (5N Plus), Japan, Slovakia, and the United States (one refiner in New York recovering and refining material from imported crude and new scrap).

In December 2024, China banned all exports of gallium to the United States, escalating controls first imposed in August 2023. Prior to the full ban, China’s 2023 export licensing requirement had already caused United States gallium metal imports to decrease and depleted stocks held outside China. USGS economic modeling estimates that a complete restriction of China’s net gallium exports could reduce United States GDP by approximately $3.1 billion, with losses concentrated in the semiconductor device manufacturing industry, which would account for more than 40 percent of the net impact. When combined with a simultaneous germanium restriction, the estimated GDP impact reaches $3.4 billion (USGS, Nassar).

16.2.1.1 Semiconductor and Power Electronics Demand

Gallium’s most significant end use is as the feedstock for compound semiconductor applications, primarily gallium nitride (GaN) and gallium arsenide (GaAs), which together account for approximately 83 percent of United States gallium consumption. Integrated circuits (ICs) accounted for 79 percent of domestic gallium consumption in 2024, with optoelectronic devices accounting for 20 percent and research and development 1 percent. Uses of ICs included defense applications, high-performance computers, and telecommunications

​

​ ​

​

equipment. In many defense-related applications, GaAs- and GaN-based ICs are used because of their unique properties, and no effective substitutes exist for GaAs and GaN in these applications (USGS).

GaN devices offer materially higher efficiency than silicon-based alternatives, enabling 50 to 80 percent lower switching losses at high switching frequencies and approximately 50 percent smaller device form factors. These properties make GaN the preferred technology for EV onboard chargers, 5G base station power amplifiers, AI data center power distribution, defense radar and electronic warfare systems, and satellite communications (Thunder Said Energy).

The global GaN semiconductor device market was valued at approximately $3.06 billion in 2024 and is projected to reach $12.47 billion by 2030, a compound annual growth rate of approximately 27 percent driven by EV powertrains, 5G infrastructure deployment, and defense electronics modernization. The United States GaN semiconductor device market is projected to grow at a comparable 26.6 percent CAGR from 2024 to 2030 (Grand View Research).

Most gallium consumed in compound semiconductor manufacturing does not reach device fabs directly as metal. Instead, it is converted by a small number of specialty chemical companies into metalorganic precursors, trimethylgallium (TMGa) and triethylgallium (TEGa), which are the critical inputs for metal-organic chemical vapor deposition (MOCVD) epitaxial growth processes. The principal western precursor producers supplying these materials to United States and allied semiconductor fabs include Merck Electronics (EMD Electronics in the United States), Entegris, and Air Liquide. These precursor producers represent the primary commercial interface between upstream gallium supply and the semiconductor device supply chain (Ramaco Internal Gallium).

Total global gallium demand is projected to grow at a 4 to 7 percent CAGR through 2030, with a high scenario of 8 to 11 percent, driven principally by GaN power electronics growth in EV charging and industrial applications, RF semiconductor demand for 5G and defense, and AI data center power conversion infrastructure (Mordor).

16.2.1.2 Market Bifurcation and Brook Mine’s Strategic Position

The global gallium market is structurally bifurcated into two distinct segments with different customers, pricing dynamics, and commercial requirements. Crude gallium, typically 2N to 4N purity, serves commodity alloying, metallurgical, and upgrading markets dominated by

​

​ ​

July 24, 2026 Page 134

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Chinese producers, characterized by thin margins and limited pricing power. High-purity electronic gallium, 6N to 7N+ purity, serves compound semiconductor applications, where stringent impurity requirements, long qualification cycles of 9 to 24 months, and supply chain traceability requirements create structurally higher margins and durable customer relationships. Once qualified, suppliers tend to remain embedded due to high switching costs (Ramaco Internal Gallium).

The ex-China addressable market for high-purity gallium is estimated at 190 to 330 tonnes per year across all product tiers, growing at approximately 6 to 7 percent CAGR. Western announced supply projects targeting this market include Alcoa of Australia (up to 100 tonnes per year), Atlantic Alumina (ATALCO) in Louisiana (up to 50 tonnes per year), Korea Zinc’s Crucible project in Tennessee (approximately 54 tonnes per year), and METLEN in Greece (50 tonnes per year target). Almost all of these operations are structured around low- to mid-purity byproduct recovery from alumina and zinc operations and are not oriented toward electronic-grade semiconductor supply chains.

The Brook Mine’s anticipated production of approximately 55 tonnes per year of gallium oxide equivalent positions it as a potentially significant contributor to western non-Chinese gallium supply at a time of acute strategic need.

The Supply and Demand forecast for Gallium Oxide is presented in Table 16-3.

**Table 16-3****Gallium Oxide: Global Long-Term Supply and Demand Forecast**

Notes:

1. Global refined gallium demand estimated at approximately 320 t/yr in 2024. Demand is expected to grow significantly through the forecast period, driven by two distinct vectors: continued growth in commodity gallium applications at 4 to 7 percent CAGR (Mordor Intelligence, 2025), and accelerating demand for high-purity electronic-grade gallium driven by GaN semiconductor devices. The global GaN semiconductor device market is projected to grow at approximately 27 percent CAGR from $3.06 billion in 2024 to $12.47 billion by 2030, driven by EV powertrains, 5G infrastructure, AI data center power distribution, and defense electronics (all of which require high-purity gallium feedstock with no effective

​

substitute). The ex-China western market for high-purity gallium is estimated at 190 to 330 t/yr currently, growing at approximately 6 to 7 percent CAGR as GaN penetration accelerates. Total global gallium demand is projected to reach approximately 700 t/yr by 2035 and 1,100 t/yr by 2045. China’s December 2024 ban on gallium exports to the United States has structurally severed western access to approximately 99 percent of primary global production, accelerating the urgency of western supply development. (USGS Mineral Commodity Summaries 2025; Grand View Research, GaN Semiconductor Devices Market Report, 2024; Mordor Intelligence, Gallium Market Report, 2025; Ramaco internal gallium market analysis, February 2026)

2. Global refined gallium production capacity estimated at approximately 340 t/yr in 2024, concentrated almost entirely in China, which accounts for approximately 99 percent of primary low-purity production. Total global supply capacity is projected to grow to approximately 550 t/yr by 2035 as announced western projects including ATALCO in Louisiana, Alcoa of Australia, Korea Zinc’s Crucible project in Tennessee, and METLEN in Greece come online, supplemented by continued Chinese capacity expansion. However, virtually all announced western projects are oriented toward crude and mid-purity byproduct material not suited to electronic-grade semiconductor supply chains, meaning the global supply increase does not address the acute western deficit in high-purity electronic-grade gallium. Western non-Chinese supply of electronic-grade material remains insufficient to meet western semiconductor demand through the forecast period. (USGS Mineral Commodity Summaries 2025; Ramaco internal gallium market analysis, February 2026; respective company public announcements)

3. Held flat at latest available forecast horizon. No credible published forecast extends beyond this point. The acute western deficit in high-purity electronic-grade gallium is expected to persist structurally given the concentration of primary gallium production in China and the qualification timelines of 9 to 24 months required for electronic-grade supply chain entry.

**16.2.2** **Gallium Pricing**

Gallium pricing is bifurcated between Chinese domestic benchmark prices and western market prices, a divergence that accelerated sharply following China’s August 2023 export controls and the December 2024 ban on United States shipments. Chinese domestic primary low-purity (4N) gallium metal prices averaged approximately $380 per kilogram in mid-2024, rising to approximately $420 per kilogram by October 2024 as western stocks depleted. The average unit value of United States imports of gallium was approximately $500 per kilogram in 2024 (USGS).

Western market prices for gallium are materially higher than Chinese domestic benchmarks, reflecting structural scarcity, supply chain security premiums, and the absence of reliable non-Chinese primary production. For 4N gallium metal, western prices are approximately $1,450 per kilogram, with high purity device-grade lots for precursor applications commanding $2,500 to $3,500 per kilogram. As of the report date, the western market premium for 4N gallium metal was over 3x the Chinese FOB price, reflecting the structural supply fragmentation

​

​ ​

July 24, 2026 Page 136

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

created by China’s export controls and the demonstrated willingness of western buyers to pay substantial premiums for non-Chinese sourced material (Fastmarkets).

There is no established western market index for gallium oxide (Ga₂O₃). For modeling purposes, a long-term gallium oxide price of $1,000 per kilogram has been used, reflecting an estimate of the western market price.

For context, the Fastmarkets western gallium metal index price was approximately $1,450 per kilogram as of end of year 2025, representing a western market premium of approximately 3.6x relative to the Chinese FOB gallium metal price of approximately $400 per kilogram over the same period. Applying the same 3.6x western premium to the Chinese domestic gallium oxide price of approximately $285 per kilogram, implies a western gallium oxide price of approximately $1,026 per kilogram (Shanghai Metals Market, Fastmarkets).

Alternatively, applying an estimated oxide-to-metal conversion cost of approximately $100 per kilogram and the stoichiometric conversion ratio of 1.344 kg Ga₂O₃ per kg Ga metal, the implied western gallium oxide price at year end 2025 would therefore be approximately $1,000 per kilogram.

These two methods were used as the basis for the long-term price assumption of $1,000 per kilogram. This represents a conservative western market price assumption when taking into account the following additional considerations:

- The structural and growing deficit in western non-Chinese gallium supply, which is expected to persist through the project’s production horizon given the absence of meaningful primary western production capacity;
- The December 2024 ban on Chinese gallium exports to the United States, which has materially severed the dominant supply relationship for United States semiconductor manufacturers;
- The projected growth of the global GaN semiconductor device market at a CAGR of approximately 27 percent through 2030, driving sustained demand growth for high-purity gallium; and
- The observed trajectory of western gallium prices, and anticipated premiums thereof, which have increased substantially since China’s August 2023 export controls and are expected to continue rising as demand growth outpaces western supply development.

​

​ ​

July 24, 2026 Page 137

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The $1,000 per kilogram assumption is therefore considered a reasonable long-term price for planning purposes at the Initial Assessment stage, subject to revision as the project advances to pre-feasibility study.

All prices are stated in United States dollars per kilogram of gallium oxide (Ga₂O₃) at 4N (99.99 percent) purity, consistent with the product specification of the hydrometallurgical flowsheet assumed in this study.

**16.3** **Germanium**

**16.3.1** **Germanium Demand and Supply**

Germanium is a metalloid recovered almost exclusively as a byproduct of zinc smelting and coal fly ash processing. There is no primary germanium mine in production anywhere in the world. China is the dominant global producer, accounting for approximately 80 to 82 percent of refined global output, with major production concentrated at Yunnan Chihong Zinc and Germanium Co. Ltd. and Yunnan Lincang Xinyuan Germanium Industry Co. Ltd. Outside China, meaningful production is limited to Teck Resources at its Trail metallurgical complex in British Columbia (approximately 11 percent of global supply), Umicore in Belgium (refining from imported concentrates), and PPM Pure Metals in Germany. The United States has no primary domestic germanium production. Germanium-containing zinc concentrates are produced at a mine in Alaska and exported to Canada for processing, while a second United States operation in Tennessee that also produced germanium-bearing zinc concentrates has been suspended since November 2023 (USGS Germanium, BNN).

Global germanium consumption is estimated at approximately 220 tonnes of metal (or 317 tonnes as germanium oxide) per year, with demand concentrated in four principal end-use sectors: fiber optics, infrared optics, semiconductor applications and solar cells, and radiation detectors. In the United States, these end uses rank in the same order of importance (USGS Germanium).

16.3.1.1 Fiber Optics

Fiber optics is the largest single end use for germanium globally, accounting for approximately 35 percent of total consumption. Germanium dioxide (GeO₂) and germanium tetrachloride (GeCl₄) are consumed as dopants during the manufacture of fiber optic glass, increasing the refractive index of the silica core and enabling the low-loss light transmission essential to data

​

​ ​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

networking and telecommunications infrastructure. A facility in Oklahoma produces germanium tetrachloride for United States fiber optic manufacturers from imported and recycled germanium. Demand from this sector is structurally linked to global data traffic growth and fiber optic network buildout, including 5G infrastructure and data center interconnects.

16.3.1.2 Infrared Optics and Defense

Germanium metal is the preferred material for infrared optical lenses, windows, and components due to its high refractive index and transparency across the 8 to 14 micron thermal infrared waveband. These properties make germanium irreplaceable in thermal imaging systems, night vision equipment, forward-looking infrared (FLIR) systems, and targeting optics used across military and aerospace platforms. In June 2025, the United States Department of Defense awarded contracts of approximately $200 million to develop AI-enhanced defense technologies including infrared and thermal imaging systems, driving further near-term demand for germanium optical components. In April 2024, the DoD awarded $14.4 million under the Defense Production Act Investment Program to expand germanium wafer manufacturing in St. George, Utah, specifically to increase domestic supply chain resilience (USGS Germanium, Polaris).

Infrared optics accounts for approximately 30 percent of global germanium consumption and the global germanium lens market is estimated to have been valued at approximately $350 million in 2023 and is projected to reach $560 million by 2032 (Astute Analytica).

16.3.1.3 Semiconductors and Solar

Germanium wafers serve as substrates for high-efficiency multijunction solar cells used in space applications, where their lattice structure enables multiple photovoltaic junctions to be grown epitaxially, achieving efficiencies well above those achievable with silicon. A facility in St. George, Utah produces germanium wafers predominantly for this application from imported and recycled germanium. Germanium compounds are also consumed in the production of germane gas used in certain semiconductor and solar cell manufacturing processes. In many of these applications, particularly defense-critical and space-grade uses, no effective substitute for germanium has been identified.

16.3.1.4 Supply Constraints and China Export Controls

In August 2023, China implemented an export licensing program for germanium, requiring all exports to carry licensed end-use commitments. China’s reported exports of germanium metal for the year through August 2024 decreased by 55 percent to 16,700 kilograms compared with the same period in 2023. In December 2024, China banned all exports of germanium to the United States entirely, an action that post-dates but is consistent with the supply risk context of this study. Prior to the ban, more than half of United States germanium imports were sourced directly or indirectly from China, with the remainder from Belgium, Canada, and Germany (USGS Germanium).

USGS economic modeling estimates that a complete restriction of China’s germanium exports could reduce United States GDP by approximately $0.4 billion in isolation, and $3.4 billion when combined with a simultaneous gallium restriction, with losses concentrated in semiconductor device manufacturing (Nassar).

Germanium applications, from fiber optics, infrared defense optics, to space solar cells, are infrastructure and national security end uses with multi-year procurement cycles where deferred purchases are not a practical response to supply disruption. This inelasticity of demand, combined with the structural concentration of supply in China, makes western primary germanium supply a strategic priority for United States and allied governments (Skillings).

Global germanium demand is forecast to grow at a CAGR of approximately 3.5 to 4.8 percent through 2030, driven by fiber optic network expansion, defense infrared optics modernization, and continued space solar cell demand (Astute, Ramaco Internal).

Brook Mine’s anticipated average germanium oxide production of approximately 13 tonnes per year would represent a meaningful contribution to western ex-China supply, which outside of Teck’s Trail operation and Umicore’s Belgian refinery has no established large-scale sources.

The global Supply and Demand forecast for Germanium Oxide is presented in Table 16-4.

**Table 16-4****Germanium Oxide: Global Long-Term Supply and Demand Forecast**

Notes:

1. Global germanium consumption estimated at approximately 220 t/yr in 2024, growing at 3.5 to 4.8 percent CAGR through 2030 driven by fiber optic network expansion, defense infrared optics modernization, and space solar cell demand, reaching approximately 280 t/yr by 2030. Demand is projected to continue growing modestly through 2045 as fiber optic infrastructure buildout extends globally and defense infrared applications expand, reaching approximately 350 t/yr. China’s December 2024 export ban to the United States has created an acute western supply deficit irrespective of global conditions. (USGS Mineral Commodity Summaries 2025; Astute Analytica, Global Germanium Market Report, August 2025; Ramaco internal demand analysis, September 2025)

2. Global germanium supply estimated at approximately 220 t/yr in 2024, with China accounting for approximately 80 to 82 percent of refined output. Non-Chinese production is limited to Teck Resources at its Trail metallurgical complex in British Columbia and Umicore in Belgium. Total global supply expected to grow modestly to approximately 250 to 270 t/yr by the mid-2030s as byproduct recovery from zinc smelting expands incrementally. China’s December 2024 export ban on germanium to the United States has created an acute western supply deficit despite broadly balanced global conditions. (USGS Mineral Commodity Summaries 2025; Nassar et al., USGS Open-File Report 2024-1057)

3. Held flat at latest available forecast horizon. No credible published forecast extends beyond this point. The acute western deficit is expected to persist structurally given China’s dominance of germanium refining and the absence of credible large-scale non-Chinese primary germanium projects.

**16.3.2** **Germanium Pricing**

Germanium pricing is well documented through European market benchmarks reported by Argus Media. Average European prices for germanium metal (minimum 99.999 percent purity) rose from approximately $1,550 per kilogram in January 2024 to approximately $2,950 per kilogram by September 2024, representing a 90 percent increase over nine months as China’s export licensing controls depleted stocks held outside China. The 2024 annual average price for germanium metal was approximately $2,100 per kilogram, and the annual average price for germanium dioxide was approximately $1,400 per kilogram (USGS, Argus).

​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

A germanium oxide price of $2,850 per kilogram has been used for modeling purposes in this study, reflecting a 7 percent discount to the Fastmarkets western index price of $3,080 per kilogram for germanium oxide as of the report date, and consistent with the western germanium metal price of approximately $2,830 per kilogram at year-end 2025. The modeled price represents a conservative western market assumption relative to the price trajectory observed through 2024 and into 2025, and reflects the structural supply scarcity created by China’s export controls (Fastmarkets).

All prices are stated in United States dollars per kilogram of germanium oxide (GeO₂) at 99.999 percent purity unless otherwise stated, consistent with the product specification of the hydrometallurgical flowsheet assumed in this study.

**16.4** **Neodymium and Praseodymium**

**16.4.1** **Neodymium and Praseodymium Demand and Supply**

Neodymium and praseodymium are light rare earth elements typically produced together as a combined oxide (NdPr oxide) and are the primary magnetic rare earth inputs for neodymium-iron-boron (NdFeB) permanent magnets, the strongest commercially available permanent magnets. NdFeB magnets are integral to electric vehicle traction motors, direct-drive wind turbine generators, industrial motors, robotics, defense systems, and consumer electronics. Over 90 percent of all electric vehicles produced today use permanent magnet traction motors containing NdFeB magnets (US DOE 2023).

Global mine production of rare earth oxides was estimated at approximately 390,000 tonnes of REO equivalent in 2024, with China accounting for approximately 270,000 tonnes, approximately 69 percent of world production. However, China’s dominance is substantially more concentrated in the downstream separation, metallization, and magnet manufacturing stages, where it holds more than 85 percent of worldwide NdFeB magnet production capacity. The United States produced an estimated 45,000 tonnes of REO in mineral concentrates in 2024, almost entirely from MP Materials’ Mountain Pass mine in California, which is the only active large-scale rare earth mining operation in the country (USGS 2025).

The United States remained heavily import-reliant for rare earth compounds and metals in 2024, with approximately 70 percent of rare earth compound and metal imports sourced from China over the 2020 to 2023 period. Significant quantities of rare earths are also imported as

permanent magnets embedded in finished goods, which are not captured in raw material import statistics.

16.4.1.1 Electric Vehicle Demand

EV traction motors are the dominant and fastest-growing driver of NdPr demand. Each EV traction motor contains approximately 1 to 3 kilograms of NdPr oxide, depending on motor design and vehicle class. Global EV sales exceeded 10 million units in 2022 and have continued to grow strongly, with IEA forecasts projecting sales of approximately 22 million EVs in 2025 and approximately 34 million by 2030 (IEA 2024).

Over 90 percent of EV traction motors currently use NdFeB permanent magnet designs, and while some manufacturers have explored motor designs with reduced or eliminated rare earth content, the performance advantages of NdFeB motors, higher power density, smaller size, and greater efficiency, means that NdFeB dominates the EV traction motor market and is expected to remain the preferred technology through the project’s production horizon.

16.4.1.2 Wind Energy Demand

Offshore wind turbines represent a second major and structurally growing demand driver. Direct-drive wind turbine generators use NdFeB permanent magnets in their nacelles, with each offshore turbine requiring 200 to 600 kilograms of rare earth elements, of which NdPr constitutes approximately 20 to 25 percent. Approximately 30 percent of all new wind turbines currently installed use direct-drive or hybrid permanent magnet designs. The IEA projects wind electricity generation to reach 7,900 TWh by 2030 under its Announced Pledges Scenario, with offshore wind growing at a CAGR exceeding 20 percent through 2030. Applying a 30 percent permanent magnet penetration rate and an average NdPr content of 232 kg per MW to projected new annual wind capacity additions of approximately 150 to 200 GW per year by 2030, wind energy applications alone are estimated to require approximately 10,000 to 14,000 tonnes of NdPr oxide per year by 2030, representing a material and growing component of total global NdPr demand (IEA 2024, US DOE 2023, Science Direct, October 2024).

16.4.1.3 Defense Demand

NdFeB magnets are critical to a broad range of defense applications including precision-guided munitions, radar and sonar systems, unmanned aerial vehicles, electric drive systems for naval vessels, and robotics. The United States government has designated NdPr oxide as a material

​

warranting strategic stockpile acquisitions, with USGS noting that FY2024 and FY2025 potential government acquisitions included NdPr oxide and NdFeB magnet block (USGS 2025).

16.4.1.4 Global Demand Outlook

Ramaco’s internal demand analysis, drawing on the United States Department of Energy’s rare earth permanent magnet supply chain analysis and IEA Announced Pledges Scenario demand projections, models global NdPr oxide demand at approximately 90,000 tonnes REO by 2030, based on global NdFeB magnet demand growing to approximately 81,000 tonnes by 2030 (equivalent to approximately 90,000 tonnes NdPr REO using a 30 wt percent REO content in magnets and a 75/25 Nd/Pr split). This represents a compound annual growth rate of approximately 5.1 percent from the 2024 baseline of approximately 66,750 tonnes NdPr REO (Ramaco Internal, IEA Announced Pledges, Project Blue).

Adamas Intelligence forecasts that global annual demand for NdPr oxide will exceed global annual production by upwards of 16,000 tonnes by 2030, equivalent to the material needed for approximately 20 million EV traction motors, with the supply gap widening thereafter unless substantial new non-Chinese production comes online (Adamas).

Western NdPr demand, defined as consumption across allied regions in EV, industrial motor, wind, and defense applications, is estimated at approximately 10,000 to 12,000 tonnes per year of separated oxide, with defense-related demand estimated at an additional 400 to 500 tonnes per year. Brook Mine’s anticipated NdPr oxide production of approximately 172 tonnes per year would represent a modest but meaningful contribution to western allied supply at a time when non-Chinese separation and processing capacity remains severely limited (Ramaco Internal).

The global Supply and Demand forecast for NdPr Oxide is presented in Table 16-5.

**Table 16-5****NdPr Oxide: Global Long-Term Supply and Demand Forecast**

Notes:

1. Global NdPr oxide demand estimated at approximately 66,750 t/yr in 2024, growing at approximately 5.1 percent CAGR to approximately 90,000 t/yr by 2030, driven principally by EV traction motors, direct-drive offshore wind turbine generators, defense applications, and industrial motors and robotics. Adamas Intelligence forecasts demand growing at a 7.5 percent CAGR from 2023 to 2040, with global NdFeB magnet demand increasing five-fold by 2040. The 2036 to 2045 demand range of 90,000 to 140,000 t/yr reflects continued growth at a moderating CAGR as EV and wind markets mature. Demand held flat at 140,000 t/yr beyond 2045 as no credible long-term forecast is available. (Ramaco internal demand analysis, September 2025; United States DOE Rare Earth Permanent Magnets Supply Chain Deep-Dive, December 2024; IEA Announced Pledges Scenario; Adamas Intelligence, Rare Earth Magnet Market Outlook to 2040, 2023)

2. Global NdPr supply estimated at approximately 66,750 t/yr in 2024, growing slowly as non-Chinese projects add incremental capacity. Adamas Intelligence forecasts global NdPr undersupply of 19,000 t/yr by 2030 and 90,000 t/yr by 2040, absent significant new non-Chinese production. China controls approximately 92 percent of refined NdPr supply. Supply held flat beyond 2040 at a conservative estimate of 80,000 t/yr reflecting limited non-Chinese expansion prospects. (USGS Mineral Commodity Summaries 2025; Adamas Intelligence, Rare Earth Magnet Market Outlook to 2040, 2023; IEA, Rare Earth Elements: Pathways to Secure and Diversified Supply Chains, 2026)

3. Held flat at latest available forecast horizon. No credible published forecast extends beyond this point.

**16.4.2** **Neodymium and Praseodymium Pricing**

NdPr oxide pricing is well documented through western market indices. The USGS MCS 2025 reports an average neodymium oxide price of $56 per kilogram for 2024 (99.5 percent minimum purity, sourced from Argus Media Group), reflecting a period of Chinese domestic oversupply and price suppression. The 2024 price represented a significant decline from the 2022 peak of $134 per kilogram and the 2023 average of $78 per kilogram (USGS, Argus).

The structural divergence between Chinese domestic prices and western market prices is most clearly evidenced by the United States Department of Defense’s July 2025 agreement with MP Materials, which established a 10-year price floor of $110 per kilogram for NdPr products. At

​

​ ​

July 24, 2026 Page 145

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

the time of announcement, this floor was approximately double the then-current Chinese-based market price of approximately $51 per kilogram realized by MP Materials in 2024, reflecting the DoD’s assessment that Chinese domestic prices are not representative of the cost of building and sustaining a viable western rare earth supply chain (MP Materials).

A NdPr oxide price of $110 per kilogram has been used for modeling purposes in this study. This price is consistent with the DoD-established price floor for western NdPr supply and represents an 11 percent discount to the Fastmarkets western index price of $124 per kilogram as of the report date. It is noted that the Fastmarkets western NdPr oxide price was approximately $97 per kilogram at year-end 2025, and that prices have been volatile due to ongoing Chinese export control measures. The $110 per kilogram assumption is considered appropriate for an Initial Assessment given its alignment with the United States government’s stated long-term price support level for domestic NdPr production (Fastmarkets NdPr, MP Materials).

All prices are stated in United States dollars per kilogram of NdPr oxide at 99.5 percent minimum purity unless otherwise stated, consistent with the product specification assumed in this study.

**16.5** **Dysprosium and Terbium**

**16.5.1** **Dysprosium and Terbium Demand and Supply**

Dysprosium and terbium are heavy rare earth elements (HREEs) added in small but critical quantities to neodymium-iron-boron (NdFeB) permanent magnets to maintain coercivity (resistance to demagnetization) at elevated operating temperatures. Without these additions, NdFeB magnets lose performance or fail in the high-temperature environments of EV traction motors, wind turbine generators, and defense and aerospace systems. Dysprosium and terbium are complementary additives from the same supply sources; terbium is more effective per unit weight but is significantly scarcer and more expensive, so the two are used in combination depending on application requirements. Both are added at approximately 1 to 5 percent by weight in high-performance NdFeB magnets (IEA, Rare Earth Elements).

Demand for magnet rare earths, including dysprosium and terbium alongside neodymium and praseodymium, has doubled since 2015 and is projected to increase by more than 30 percent by 2030, driven by accelerating EV adoption, offshore wind deployment, industrial motor electrification, robotics, and defense system modernization.

​

16.5.1.1 Role in EV and Wind Applications

High-performance NdFeB magnets for EV traction motors and direct-drive wind turbine generators require dysprosium and terbium additions to maintain coercivity at the operating temperatures encountered in these applications. Each NdFeB magnet typically contains 4 to 8 percent dysprosium and terbium by weight in high-temperature motor applications. Global battery electric vehicle production of approximately 13.6 million units in 2023 consumed an estimated 100 to 120 tonnes of dysprosium for motor applications alone. Projected EV production of 40 to 50 million units annually by 2030 would require 200 to 450 tonnes of dysprosium per year for motor applications alone (IEA, World Energy Outlook).

16.5.1.2 Supply Concentration and China’s Dominance

Dysprosium and terbium are geologically distinct from light rare earths such as NdPr. They are found in commercially viable concentrations almost exclusively in ionic clay deposits, which are geographically concentrated in southern China and Myanmar. China controls over 90 percent of global dysprosium and terbium production, not only through mining but through its near-monopoly on separation and refining capacity, which represents the true bottleneck in the HREE supply chain (Benchmark).

A large share of China’s heavy rare earth feedstock originates from ionic clay deposits in Myanmar’s Kachin State, which are estimated to supply approximately 70 percent of China’s HREE feedstock. These operations are frequently disrupted by conflict between Myanmar’s military and the Kachin Independence Army, creating a secondary source of price volatility that compounds the geopolitical concentration risk. In early 2025, Chinese imports of heavy rare earths from Myanmar declined by approximately 50 percent due to armed group activity, contributing to price spikes for dysprosium and terbium (Rare Earth Exchanges, Rare Earth Mining).

On April 4, 2025, China introduced export controls on seven heavy rare earth elements including dysprosium, terbium, samarium, gadolinium, lutetium, scandium, and yttrium, as well as all related compounds, metals, and NdFeB magnets containing these elements. Export volumes fell sharply in April and May 2025, with many automakers in the United States, Europe, and elsewhere forced to cut production line utilization rates or temporarily suspend manufacturing due to magnet shortages. While export licenses were eventually granted and volumes partially recovered, prices for dysprosium and terbium in importing countries remained materially elevated.

​

According to Benchmark Mineral Intelligence, the West will still rely on China for approximately 91 percent of its heavy rare earth needs by 2030, down only marginally from approximately 99 percent in 2024. HREE refining is expected to increase globally by approximately 2029, but costs outside China remain 5 to 7 times higher than Chinese production costs, creating a structural barrier to rapid supply diversification (Benchmark).

Adamas Intelligence forecasts that global undersupply of dysprosium and terbium oxides will rise to 1,800 tonnes and 450 tonnes per year respectively by 2040, amounts roughly equal to total global production of each oxide today, absent significant new non-Chinese production capacity (Adamas as cited in mining.com).

CRU forecasts a global deficit of approximately 2,920 tonnes in the combined dysprosium and terbium oxide supply/demand balance by 2035.

16.5.1.3 Western Supply Pipeline

Outside China, credible near-term sources of separated heavy rare earth production are extremely limited. Lynas Rare Earths in Australia has become the first company outside China to produce commercially separated heavy rare earths, though its Mount Weld deposit is light-REE dominant and HREE output remains marginal relative to global demand. Other projects remain pre-production. Iluka Resources is constructing a refinery at Eneabba in Western Australia with capacity to process up to 750 tonnes per year of heavy rare earths, targeted for commissioning in 2027. By 2035, existing and announced capacities outside China are expected to cover only approximately half of mining requirements, a quarter of refining needs, and less than a fifth of magnet demand (IEA Rare Earth Elements).

The Brook Mine’s anticipated dysprosium oxide production of approximately 19 tonnes per year and terbium oxide production of approximately 4 tonnes per year are modest in the context of global demand but represent meaningful contributions to western allied supply at a time when non-Chinese separation capacity is structurally inadequate relative to demand.

Western dysprosium demand is projected at approximately 1,020 tonnes per year and western terbium demand at approximately 180 tonnes per year, for a combined western HREE demand of approximately 1,200 tonnes per year by the project’s anticipated production horizon (Ramaco Internal).

The global Supply and Demand forecast for Dysprosium Oxide is presented in Table 16-6 and the global Supply and Demand forecast for Terbium Oxide is presented in Table 16-7.

**Table 16-6****Dysprosium Oxide: Global Long-Term Supply and Demand Forecast**

Notes:

1. Global dysprosium demand growing with NdFeB magnet demand at approximately 7.5 percent CAGR from 2023 to 2040, driven by high-performance EV traction motors and direct-drive wind turbine generators requiring dysprosium additions to maintain coercivity at elevated operating temperatures. Global battery electric vehicle production of approximately 13.6 million units in 2023 consumed an estimated 100 to 120 t of dysprosium for motor applications. Projected EV production of 40 to 50 million units annually by 2030 would require 200 to 450 t/yr of dysprosium for motor applications alone. The 2036 to 2045 demand range reflects continued growth at a moderating rate as EV and wind markets mature. Demand held flat beyond 2045 as no credible long-term forecast is available. (IEA, World Energy Outlook 2024; Adamas Intelligence, Rare Earth Magnet Market Outlook to 2040, 2023; Discovery Alert, “Heavy Rare Earth Shortages,” November 2025)

2. Global dysprosium production almost entirely from Chinese ionic clay processing, with Myanmar’s Kachin State deposits supplying approximately 70 percent of China’s HREE feedstock. China controls over 90 percent of global dysprosium production through mining and near-monopoly refining capacity. Non-Chinese production remains limited to marginal output from Lynas Rare Earths and other sources. Supply growth expected to be negligible beyond current levels through the forecast period given absence of credible non-Chinese expansion projects. (Benchmark Mineral Intelligence, as cited in US News, November 2025; USGS Mineral Commodity Summaries 2025)

3. Held flat at latest available forecast horizon. No credible published forecast extends beyond this point. Adamas Intelligence forecasts dysprosium undersupply of 1,800 t/yr by 2040. (Adamas Intelligence, Rare Earth Magnet Market Outlook to 2040, 2023)

**Table 16-7****Terbium Oxide: Global Long-Term Supply and Demand Forecast**

Notes:

1. Global terbium demand growing in tandem with dysprosium as a complementary NdFeB magnet performance additive, at approximately 7.5 percent CAGR from 2023 to 2040. Terbium is more effective per unit weight than dysprosium but is significantly scarcer, constraining its use relative to theoretical demand. CRU forecasts a combined dysprosium and terbium oxide deficit of approximately 2,920 t/yr by 2035. The 2036 to 2045 demand range reflects continued growth at a moderating rate. Demand held flat beyond 2045 as no credible long-term forecast is available. (Adamas Intelligence, Rare Earth Magnet Market Outlook to 2040, 2023; CRU, as cited in US News, November 2025)

2. Global terbium production almost entirely from Chinese ionic clay processing, co-produced with dysprosium from the same deposits. Current global production estimated at approximately 400 to 450 t/yr. Non-Chinese production negligible. Supply growth constrained by geological concentration and Chinese dominance of processing. (USGS Mineral Commodity Summaries 2025; Benchmark Mineral Intelligence, as cited in US News, November 2025)

3. Held flat at latest available forecast horizon. No credible published forecast extends beyond this point. Adamas Intelligence forecasts terbium undersupply of 450 t/yr by 2040. (Adamas Intelligence, Rare Earth Magnet Market Outlook to 2040, 2023)

**16.5.2** **Dysprosium and Terbium Pricing**

Dysprosium and terbium pricing is documented through Argus Media and Fastmarkets western market indices. Both elements exhibit extreme price sensitivity to Chinese export policy, Myanmar supply disruptions, and western procurement behavior, with price swings of 50 to 100 percent or more occurring within single years in response to supply events.

USGS MCS 2025 reports the average dysprosium oxide price at approximately $260 per kilogram for 2024 (99.5 percent minimum purity, sourced from Argus Media Group, Argus Non-Ferrous Markets), representing a decline from the 2022 peak of approximately $382 per kilogram. Terbium oxide averaged approximately $810 per kilogram in 2024, down from the 2022 peak of approximately $2,051 per kilogram. These declines reflected a period of Chinese domestic oversupply and price suppression, which reversed sharply following China’s April 2025 export controls (USGS).

​

​ ​

July 24, 2026 Page 150

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Following China’s April 2025 export controls, western prices for dysprosium and terbium rose substantially. The Fastmarkets western index price for dysprosium oxide was approximately $1,180 per kilogram as of the report date, and approximately $1,120 per kilogram at year-end 2025. The Fastmarkets western index price for terbium oxide was approximately $5,030 per kilogram as of the report date, and approximately $4,850 per kilogram at year-end 2025 (Fastmarkets).

A dysprosium oxide price of $975 per kilogram has been used for modeling purposes in this study, representing a 17 percent discount to the Fastmarkets western index price of $1,180 per kilogram as of the report date. A terbium oxide price of $4,500 per kilogram has been used for modeling purposes in this study, representing an 11 percent discount to the Fastmarkets western index price of $5,030 per kilogram as of the report date. Both modeled prices represent conservative western market assumptions. The current western premium for dysprosium and terbium relative to Chinese domestic prices is approximately 4.5x to 4.7x, reflecting the structural supply fragmentation created by China’s export controls and the absence of viable alternative western sources.

All prices are stated in United States dollars per kilogram of oxide at 99.5 percent minimum purity for dysprosium oxide (Dy₂O₃) and 99.99 percent minimum purity for terbium oxide (Tb₄O₇), consistent with the product specifications assumed in this study.

**17.0** **Environmental Studies, Permitting, and Plans, Negotiations, or Agreements with Local Individuals or Groups**

Ramaco was issued Permit No. 841-T1 (Mining Permit) on July 7, 2020 by the LQD of the WDEQ for surface coal mining in Sheridan County, Wyoming. The Mining Permit consists of 4,541 acres.

The Mining Permit does not specifically identify mining rights of non-coal material, however, as the TCM resource is inseparable from the coal mining production process, per OSM regulation 30 CFR 700.5, a separate mining permit for the TCM resource is not required for non-coal mining activity. However, a revision will be required to account for the CMO processing and tailings facilities. The revision will require a detailed engineering design and environmental study, including an updated reclamation plan, additional surety bond sized to cover full reclamation, long-term tailings closure, and water treatment, if needed.

A WYPDES permit is required for any point-source discharge from the process plant, tailings underdrains, stormwater contact areas, or pit dewatering. Ramaco was issued WYPDES Industrial Stormwater Authorization No. WYR001608 (issued June 1, 2023, effective May 1, 2024, expiring May 31, 2028), with required semi-annual benchmark sampling for total suspended solids and total recoverable aluminum and annual benchmark reporting to WDEQ.

Additionally, the Air Quality Division of the Wyoming Department of Environmental Quality issued Air Quality Permit P0025939 on July 20, 2020, for the planned Brook Mine, as described in Wyoming Permit No. 841-T1.

The planned Brook Mine has an MSHA ID# of 4801799.

**17.1** **Environmental Studies**

In support of the WDEQ LQD Permit to Mine application for the Brook Mine, Ramaco Resources commissioned WWC Engineering to conduct an extensive program of baseline studies and impact assessments that collectively characterize the pre-mining environment of the permit and adjacent areas. These investigations form the technical foundation underpinning the LOM Plan and provide the environmental baseline relied upon for purposes of this TRS.

​

​ ​

July 24, 2026 Page 152

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The baseline studies and impact statements include the following:

- A land-use inventory documenting current and historic land uses, land ownership, surface improvements, and oil-and-gas wells within and surrounding the Permit Area;
- A history and cultural-resources review summarizing nineteenth- and twentieth-century mining and settlement of the area, with archaeological and paleontological resources determined not applicable
- A climatology baseline of regional precipitation, temperature, wind, and evaporation regimes;
- A topography, geology, and overburden assessment, incorporating geologic mapping, stratigraphic cross-sections, geologic-hazards screening, and an overburden-quality sampling and characterization program used to confirm the absence of acid- or toxic-forming strata;
- A hydrology baseline of nearly 1,900 pages addressing pre-mining surface-water and groundwater conditions, surface-water and groundwater monitoring networks, stream-channel geomorphology, water rights, and aquifer pump-test results;
- A soil resources assessment, including soil mapping, characterization, salvage-depth determinations, and a prime-farmland evaluation;
- A vegetation inventory quantifying community types, production, cover, and species composition for use in establishing reclamation success standards;
- A wildlife baseline covering big game, raptors, migratory birds of high federal interest, greater sage-grouse leks, and threatened-and-endangered species, together with the impact analysis and mitigation framework subsequently codified in the Wildlife Monitoring Plan and the Raptor/MBHFI Mitigation Plan;
- A wetlands delineation conducted in accordance with United States Army Corps of Engineers methodology;
- An alluvial valley floor (AVF) investigation evaluating the Tongue River, Goose Creek, and tributary drainages for AVF characteristics and the potential for material damage from mining.

Together with the probable hydrologic-consequences determination, the operational surface-water, groundwater, and alluvial monitoring programs, and the impact-mitigation plans set forth in the Mine Plan, these baseline studies represent a comprehensive, regulator-reviewed environmental characterization of the Brook Mine property that support the environmental-studies, permitting, and social-license disclosure information provided in accordance with Item 601(b)(96)(iii)(B)(17) of Regulation S-K 1300.

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**17.1.1** **Groundwater Inventory and Baseline Quality**

Ramaco conducted pre-mine surveys to inventory water use and to determine the extent and purpose of ground water usage in areas that could be affected within ½ mile of the mine permit boundary. Field teams made door-to-door visits to these potentially affected residents to gather information by way of completing questionnaire forms regarding water supply source(s), extent of reliance, purpose of reliance (domestic, agricultural, etc.), depth of well(s), character of springs, and other relevant data as available. The teams measured water level depths in wells where possible and agreeable by owners and obtained surveyed locations accordingly. The detailed results of the surveys are included in the site’s WDEQ permit application for the Brook Mine.

Pursuant to WDEQ regulations, Ramaco is in the process of drilling numerous ground water monitoring wells to the Wall Seam, in order to conduct water monitoring necessary to be able to revise the Mining Permit in the future to allow mining down to the Masters Seam.

**17.1.2** **Surface Water Baseline Quality, Quantity, and Runoff Analysis**

Baseline surface water monitoring for flow and quality parameters was conducted at strategic, WDEQ approved locations, as applicable, over a period of twelve months for the permit area, weather permitting. During mining and through the final release of the permit, the four monitoring stations selected for the site will be monitored in accordance with the approved surface water monitoring plans, as per the mine permit. Data collected during this period will be compared with the pre-mining baseline data to determine if and how the operation is affecting surface water systems.

A surface water runoff analysis was performed in the watersheds associated with the mine permit area to evaluate the potential impact of proposed operations on flooding and streamflow alteration. Peak discharges were calculated for the “pre-mining”, “during-mining”, and post-mining” conditions and were compared. This analysis and results are included in the mine permit and show that there will be no increase in peak discharge during mining or post mining for the permit area. Original laboratory data sheets for surface and ground water baseline monitoring are included in the mine permit.

Based on analyses of overburden samples reported in the mine permit, neither acid mine drainage nor dissolved metals will pose any significant problems at the site as almost all analyses show levels below WDEQ thresholds. During mine operations, overburden samples

​

​ ​

July 24, 2026 Page 154

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

will be taken and analyzed for each 40-acre sampling unit. Should any strata be considered unsuitable based upon the permit criteria, overburden stripping and backfilling operations will be scheduled so that the identified unsuitable strata are; 1) not placed in the uppermost four feet (rooting zone) of the final backfill thickness, 2) not within six feet of the spoil surface beneath ephemeral stream channels, and 3) not within 10 feet of the spoil surface beneath permanent impoundments or major channels and associated 100-year floodplains.

**17.1.3** **Probable Hydrologic Consequences**

Probable Hydrogeologic Consequences (PHCs) were evaluated for the permit area. The planned Brook Mine is expected to have an extremely small effect on surface water quality in the Tongue River and other major streams adjacent to the permit boundary of the Brook Mine. As such, no adverse effect on the designated water uses related to the major streams adjacent to the permit boundary is expected.

The overlying strata contains no significant aquifers other than, perhaps, the coal seams. The majority of private wells are completed in geologic structures below the coal seams proposed to be mined, and any impacts to domestic users are expected to be low. There is no anticipated impact to water rights downstream of the permit boundary.

Baseline monitoring has not indicated any interactions between surface and ground water. Ongoing and expedient reclamation will ensure that the surface water hydrologic balance and flow characteristics are returned to resemble pre-mining conditions.

Postmining monitoring will confirm the mitigation of impacts once mining and reclamation have concluded. In addition, surface water rights that are disturbed or affected by the mining operations of the planned Brook Mine will have an alternate water source of similar quantity and quality provided until such time that the original water right’s functionality is restored. The PHC studies and results are included in the mine permit.

**17.1.4** **United States Army Corps of Engineers**

The United States Army Corps of Engineers (USACE) determined that Slater Creek and adjacent wetlands are the only Waters of the United States within the planned Brook Mine as defined at 33 CFR Part 328.3(a). Therefore, these are the only areas that will require USACE notification prior to disturbance. However, that delineation work was completed before the U.S Supreme Court decision in Sackett v. EPA, 598 U.S. 651 (2023), which significantly narrowed

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

the scope of federally jurisdictional wetlands under the Clean Water Act. Accordingly, the original determination may be overly inclusive.

Impacts to the delineated wetlands will fall within two categories; 1) some wetlands will be physically removed or disturbed by mining activities, and 2) other wetlands potentially impacted by reducing or eliminating their contributing drainage areas for a temporary time period. Once mining is completed in these areas, the drainage areas will be restored and flow to the wetlands will resume. In such cases, mitigation will consist of flow restoration only with no specific wetland construction required.

**17.2** **Refuse Disposal and Water Management**

**17.2.1** **Refuse Disposal**

There will be no need for coal refuse disposal at the site since the coal will be sold as a direct shipped thermal coal product. Current plans included dry stacking of tailings. The Brook Mine is not anticipated to utilize the heap leaching process.

**17.2.2** **Water Monitoring and Management**

In order to determine the impact of existing and proposed operations on the hydrologic balance, surface water samples are collected at least bi-monthly from four surface water monitoring stations which were established in September 2013. No specific water treatment facilities other than sediment control are required or planned for the Brook Mine, which is consistent with other PRB mines. However, several other PRB mines capture equipment wash down water and water used for other industrial/maintenance uses at the mines and treat that water before it is discharged.

Surface water management for the permitted mining area generally involves a combination of structures such as; 1) sediment ditches, 2) temporary sedimentation ponds, 3) permanent and temporary diversion ditches, 4) corrugated metal pipe (CMP) placement for drainages that cross access roads or haul roads, and 5) drainage diversion ditches and collections for excess spoil disposal areas. Detailed designs for all drainage and sediment control structures are included in the Brook Mine’s permit.

Discharges from these structures will be monitored in accordance with the approved plans. Sediment structures will be cleaned or enlarged if the total suspended solids exceed effluent

​

​

limitations. All discharges will flow through sediment control structures. The pond discharges will be monitored in accordance with approved plans and treated to meet effluent limitations, if needed.

Within twenty-four hours of a one-year frequency, twenty-four hour storm event or greater, a permit-wide inspection and report of the drainage systems will be completed and submitted to the WDEQ, as applicable. The inspection and subsequent report will note any damages or deficiencies in the drainage system so that repairs can be implemented immediately as well as if any sediment structure is at or near its clean out capacity (60 percent). A rain gauge, located at the iCAM office, is used to monitor precipitation events. This rain gauge is monitored daily and reported monthly to WDEQ.

Construction of the baseline groundwater monitoring network began in the third quarter of 2013 and was completed early in the fourth quarter 2013. The groundwater monitoring network consists of nine Carney Seam wells, 10 Masters Seam wells, eight alluvium wells, one underburden well, and one well perforated in both the Masters and Carney coal seams. No monitoring wells were completed in the overburden or interburden as no water was found in these units during drilling operations. Samples are taken quarterly from these monitoring wells.

Water samples are sent to a qualified laboratory and analyzed for the following parameters: flow, pH, total acidity, total alkalinity, total iron, total manganese, total sulfates, total suspended solids, and total dissolved solids or specific conductance at 25°C. The samples collected during and after mining will be compared with each other, and with the data collected during the baseline surface water study and used to determine the impact the mining operation has on the water in the receiving streams.

A quality assurance and quality control program for the water samples will entail duplicate samples (approximately 10 percent), sample preservation blanks (approximately 10 percent). All water monitoring programs are currently active.

**17.3** **Bonding and Asset Retirement Obligations**

A total bond amount of approximately $1.47 million, posted by Ramaco and in effect as of 12/31/2025, is based on the mine closure reclamation liability cost estimate prepared in early 2025. Bond estimates utilize the WDEQ bond matrix that determines the rate per acre based upon land activity. This rate per acre is simply applied to the permit site’s acreage to obtain the bond requirement. An annual inspection by the WDEQ on August 19, 2025, however,

​

​ ​

July 24, 2026 Page 157

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

resulted in a reduction in the current reclamation liability to $1.25 million due to decreased costs from Guideline 12, as well as lower costs associated with the coal storage demolition. Therefore, Ramaco’s bond amount for the Brook Mine is greater than Wyoming state requirements.

The current Asset Retirement Obligations (ARO) estimate as of October 2025 was $240,475. Ramaco plans to prepare an updated estimate for the LOM Plan, including the TCM process plant and waste management once designs have been completed.

**17.4** **Local Stakeholders**

As indicated in Section 13.4.2, Ramaco had 10 employees at the iCAM facility as of the end of 2025 and currently employs 12 personnel in Sheridan County, Wyoming and is projected to have maximum employment of approximately 190 personnel at full production. The complex creates substantial economic value with its third-party service and supply providers, utilities and through payment of taxes and fees to local, state and federal governmental agencies.

**17.5** **Mine Closure Plans**

Upon mine closure, areas will be backfilled and reclaimed to a near Approximate Original Contour (AOC) in accordance with permit requirements. A preliminary conceptual closure cost of $100 million has been estimated based on benchmark projects of similar scale and commodity in the region and is accurate to within -30 percent/+50 percent. This estimate will need to be refined through future engineering studies and site-specific baseline work. Regrading and backfilling activities are required to commence within 180 days after the mining operations are complete.

The primary pre-mining land use for the Brook Mine is agriculture land and the approved post-mining land use for the Brook Mine permit is agriculture land. No land within the permit area has been known to be used for prime farmland.

Reclamation of the mined surface areas will follow coal and TCM extraction in accordance with plans included in the current WDEQ Land Quality Permit. The land will be graded to blend with existing topographic features. Drainage systems will be reestablished. Some internally drained areas (playas) will be created to replace those existing in the pre-mine landscape. Contoured surfaces will be dressed with topsoil and planted to a variety of grasses, forbs, and shrubs.

​

​ ​

July 24, 2026 Page 158

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Upon completion of mining operations and regrading, topsoil will be redistributed over the disturbed areas. After topsoil has been replaced, soil analyses will be performed to validate quality of the topsoil. All regraded and topsoiled areas will be revegetated as soon as practical to establish quick vegetative cover to minimize erosion. Runoff from the regraded areas will be routed through properly constructed and maintained sediment structures that are designed to retain runoff long enough for the suspended solids to settle.

Temporary erosion control vegetative cover will be established as contemporaneously as practical, with backfilling and grading, until a permanent vegetative cover can be established.

Prudent handling and mixing of zones of concern to meet WDEQ/LQD Guidelines will eliminate postmining contamination problems and aid reclamation efforts. For these reasons, Ramaco believes that overburden analyte exceedances will not pose a significant problem to meet WDEQ/LQD reclamation standards.

**17.6** **Environmental Compliance, Permitting, and Local Individuals or Groups Issues**

The Brook Mine Permit No. 841-T1 is currently approved to mine coal and up to 16-2/3 percent by weight of other minerals with a combination of surface and highwall mining. The Brook Mine also has an approved WDEQ/AQD permit in support of the mining operation. Ramaco has not been cited for any violations of its permit requirements.

Vertically, the current mining permit includes the Monarch, and Carney seams. The current mining permit does not include the Masters Seam, or seams below it. However, given the existing exploration data in the Masters Seam and lower seams within the Brook Mine, this report includes coal and TCMs at those elevations, regardless of their inclusion in the existing mining permit. Ramaco is in the process of drilling groundwater monitoring wells to the Wall Seam, which will allow revising the permit to include mining down to the Masters Seam.

In order to account for the mine plan proposed in this TRS, a revision to the permit is likely to be required to revise the permitted method of mining from trench/HWM to surface mining and to allow surface mining from the Masters Seam down to the Lower 7 Seam. Ramaco will also need to increase the size of the crushing/grinding equipment needed to size the coal that will be sold to a third party, and to size the material that will report to the TCM process plant. The reclamation plan will also need to be modified to account for the increased volumes of material

​

​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

moved. In addition, Ramaco will need to revise the existing air permit accordingly and a permit(s) through the State Engineers Office (SEO) may need to be obtained.

For the TCM process plant, additional Wyoming regulatory and/or county zoning approvals will be required. In particular, Ramaco will likely need to obtain permits from other regulatory programs before constructing or operating facilities used to chemically concentrate or process critical minerals commercially. These may include, but are not limited to:

- Industrial Siting Permit from the Wyoming Industrial Siting Council if the process plant meets the applicable construction cost or facility thresholds, which is likely. Ramaco is in the process of identifying engineering firms to assist with this permit.
- Air Quality Permit from the WDEQ/AQD for emissions associated with any processing activities.
- Water Quality Permit from the WDEQ/WQD if the processing activities involve wastewater discharge, process water management, or construction of facilities requiring water pollution control permits.

WEIR is not aware of any current notice of violation, cessation order, bond forfeiture proceeding, consent decree, or unresolved environmental enforcement matter affecting the property; however, WEIR has not performed an independent environmental compliance audit, and any extension of operations beyond the existing surface coal mining scope to incorporate critical-mineral processing or tailings storage will require new or amended air, water, solid-waste, and (depending on uranium and thorium content of feedstocks) Wyoming radiogenic-materials authorizations that are not within the existing compliance perimeter.

WEIR is also not aware of any active organized community-group opposition, public-interest litigation, or formal protest filed against the existing permit as of the date of this TRS.

**18.0** **Capital and Operating Costs**

The estimated initial capital cost for the project is $579 million, which includes the proposed process plant, site infrastructure, and mine development. Total mine and TCM process plant operating costs at full production (including coal mining and selling costs), are estimated at approximately $87.70 per metric tonne of mill feed.

Capital and operating cost estimates were developed by Fluor and reviewed by the QP. The QP considers the estimates reasonable for the level of study and has adopted them for purposes of this TRS.

**18.1** **Capital Expenditures**

**18.1.1** **Estimate Methodology**

Process design criteria were developed based on preliminary testwork and process simulation of the Brook Mine flowsheet. A mass balance was generated to support sizing and pricing for the mechanical equipment list (MEL).

The mechanical equipment list was priced using a combination of budgetary vendor quotes, Fluor’s In-house cost database and Industry-standard factoring methods.

The priced MEL formed the basis of the capital cost estimate. For additional scope elements including site preparation and improvements, plant roads, site infrastructure, power supply and distribution, plant utilities, and water systems - costs were estimated using percentage-based benchmarks derived from Fluor’s database for similar plant types.

**18.1.2** **General Assumptions and Qualifications**

The following assumptions and qualifications were used in determining the capital expense estimate.

- The cost estimate is in United States dollars
- The estimate was based on a typical contracting strategy of EPCM directly managing subcontractors by the typical discipline/trade scope
- The project execution is based on a greenfield project

​

​ ​

July 24, 2026 Page 161

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

- The primary estimating procedure for developing process scope and costs is by “factoring” on the plant capacity costs
- No demolition scope is included in the estimate
- The estimate does not include any work associated with removal of contaminated materials and hazardous waste. This applies to handling, removal, disposal, and remediation of asbestos, lead paint, galvanizing fluids, contaminated soils, or disposing of process fluids

**18.1.3** **General Exclusions**

General exclusions in the capital cost estimates include the following:

- Sunk costs
- Fluctuation of currency exchange rates
- Force majeure, labor strikes and other business interruption risks
- Unknown site conditions and scope changes

Ramaco provided the capital costs for mine development, the pilot plant, and site preparation for the filtered residue placement as shown in Table 18-1 and Table 18-2. Expansion of the residue storage facility is captured in sustaining capital costs. Mining is conducted with leased equipment, similar to other Ramaco mining operations and is included in mine operating costs.

**Table 18-1****Mine Capital Cost Estimate Summary**

Initial capital for the pilot plant and residue storage site preparation for the first three years was estimated to be $16M.

Total estimated initial capital expenditures for development of the Brook Mine are $579 million, with a summary of the capital expenditures by cost area provided in Table 18-2 as follows:

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Table 18-2****Total Initial Capital Cost Estimate Summary**

**18.1.4** **Conclusions**

The capital cost estimate is $579 million including contingency of $106 million for the process plant scope. The contingency cost is estimated at 25 percent of process plant direct and indirect costs. The total capital cost estimate has an accuracy range of -30 percent to +50 percent.

**18.2** **Operating Costs**

The estimated total operating costs at full operation average $87.70 per tonne of TCM mill feed. Costs by category are summarized in Table 18-3 as follows:

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**18.2.1** **Basis of Estimate**

Mine operating costs were estimated by Ramaco’s mining group and based on mining cost inputs for similar coal operations. Mining costs also include a royalty of $0.10 per ton of coal sold relative to the SWCC royalty agreement.

The process plant operating cost estimate includes processing areas from mill feed through to product handling. The estimate includes four primary cost categories:

- Labor
- Utilities - Electricity, Raw Water, and Natural Gas
- Reagents and Consumables
- Maintenance Supplies

Process operating costs are noted below in Table 18-4.

**Table 18-4****TCM Process Plant Annual Operating Costs**

Reagents and consumables, the largest component of the processing costs, were estimated using unit consumption rates and delivered unit costs. Consumption rates were derived from metallurgical testwork, mass balance, and design assumptions. Delivered unit costs were supported by supplier discussions and internal benchmarks.

Labor estimates for the plant were based on plant operating 24/7 with four 12-hour shift rotations. Non-shift labor is based on a 40-hour work week. Staffing levels were benchmarked against similar-scale operations. Labor rates were sourced from the United States Bureau of Labor Statistics (OEWS) for Wyoming.

​

​ ​

July 24, 2026 Page 164

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Power consumption was estimated from the electrical loads, factoring in equipment run times and required power. A grid power rate was provided by Ramaco. Maintenance supplies were estimated as a percentage of the total direct installed cost for the process plant. General and administrative costs were estimated from the total estimated site headcount of 190 personnel (mine, process, and general and administration) and using an actual $/person rate from existing Ramaco operating mines.

**18.2.2** **General Exclusions**

The following items are excluded from the process plant operating cost estimate:

- Sustaining capital
- Insurance
- Import duties and taxes
- Inflation

**18.2.3** **Direct Labor Costs**

The cost for mine and general administrative labor is accounted for in the general and administrative costs. Labor rates were sourced from the United States Bureau of Labor Statistics (OEWS) for Wyoming in May of 2024 and then adjusted for inflation using information to March of 2025 levels. The total compensation was calculated using the United States Bureau of Labor and Statistics, Mountain Census Region total compensation multiplier.

**18.2.4** **Cost Estimation Risk**

Capital and operating costs are estimated to an accuracy of -30 to +50 percent, with a contingency of 25 percent. These estimates meet the accuracy and contingency requirements for an Initial Assessment.

​

**19.0** **Economic Analysis**

**19.1** **Methodology**

A preliminary cash flow model was prepared to assess the reasonable prospects of economic extraction for the planned Brook Mine.

The QP relied on certain information supplied by the Registrant’s finance personnel regarding taxes, royalties, and depreciation in the financial model. The QP reviewed the information for consistency with industry practice and considers such reliance reasonable.

**19.1.1** **Modeling Framework**

The financial model is a Discounted Cash Flow (DCF) model developed on an annual basis over a 40-year LOM. Before and after-tax discounted Net Present Value (NPV) and Internal Rate of Return (IRR) are estimated with integration of the following inputs:

- Mill feed schedule developed from the LOM Mine Plan
- Process recoveries and product specifications
- Capital cost estimates
- Operating cost estimates
- Taxes, royalties, and depreciation
- Commodity price forecasts from marketing studies

The model is constructed in real terms (constant dollars) unless otherwise stated, and excludes financing costs.

**19.2** **Financial Model Parameters**

**19.2.1** **Cut-Off Grade**

A Net Smelter Return (NSR) cut-off grade approach is used for the Brook Mine due to its polymetallic nature. The NSR approach converts all payable metals into a single dollar value per tonne ($/t). This is outlined in detail in Sections 11 and 13.

​

​ ​

July 24, 2026 Page 166

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**19.2.2** **Metallurgical Recoveries and Product Quality**

Metallurgical recoveries were based on eight months of bench scale test results conducted on the flowsheet. Specifically, the pre-feed treatment and multi-stage leaching unit operations. Recovery assumptions were made through the back end of purification, separation and finishing based on benchmarks from similar commercial operating plants. Product samples for testing were not produced at this phase of the project, so no penalty charges were included in the model. Once product samples are generated at pilot phase, potential penalties will be assessed.

**19.2.3** **Commodity Prices**

Seven TCM products for the Brook Mine are expected to have reasonable prospects of economic extraction. All other rare earth and critical minerals were excluded from the financial model. Pricing used for the Resource pit shell in Section 11 was based on early 2025 pricing while updated pricing as of the end of 2025 is used in the financial model as described in Section16. Pricing used for financial modeling is shown in Table 19-1.

**Table 19-1****Commodity Prices and Recoveries**

**19.2.4** **Mineral Resource and Mine Plan**

The LOM Plan was based on the revenue factor 0.68 pit shell and includes annual tonnes of mine waste, annual tonnes and grade for mill feed and stockpile movements. The annual process plant mill feed throughput was constrained to 2.6 million dry tonnes per year.

​

​ ​

July 24, 2026 Page 167

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The LOM Plan contains 100 percent Inferred Resources upon which this economic analysis is based.

**19.2.5** **Operating Costs**

Operating cost estimates have been developed on a LOM Plan basis for mining, processing, dry stack residue hauling and placement, and general & administrative costs. They are reported on a unit basis in $/tonne mined and processed and total annual costs. The basis for development of operating cost estimates is outlined in detail in Section 18.

**19.2.6** **Capital Costs**

Pre-production capital allocation occurs over an assumed 30-month execution duration. Detailed execution plans will be created in future stages of the project. More information on the basis of the capital cost estimate is contained in Section 18.

Sustaining capital for mining and process plant dry stack residue liner placement are included in the model.

**19.2.7** **Taxes and Royalties**

No state income taxes apply in Wyoming. The SWCC coal royalty of $0.10 per clean ton of coal is included in mine operating costs in the financial model. The following taxes were assumed in the model:

- Section 45X Advanced Manufacturing Production Tax Credit is an incentive designed to boost domestic production of critical minerals essential for clean energy, advanced electronics, and defense applications. It is intended to encourage United States-based extraction, processing, and recycling of critical minerals to strengthen supply chains and reduce reliance on imports. The credit amount is 10 percent of production costs, including depreciation, for eligible critical minerals.
- Wyoming severance tax for the coal portion is 6 percent of gross coal revenue
- Sheridan County ad valorem tax is 4 percent of gross coal revenue
- Total TCM extractive related taxes are 4 percent of gross TCM revenues
- Federal corporate tax, applied after state taxes and after payback period is 21 percent of total revenue.

​

​ ​

July 24, 2026 Page 168

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

Taxes and royalties included in Section 11 as part of the pit optimization were based on initial assumptions. Over the course of 2025, Ramaco has revised their assumptions around TCM extractive taxes, as the TCMs have not historically been specifically referenced in the Wyoming extractive tax regulations, it was assumed in the financial modeling that some level of collaboration with the State is anticipated. Therefore, a total of 4% for TCM extractive related taxes has been included in the financial model.

**19.2.8** **Depreciation**

Depreciation is included in the model and calculated based on actual units of production output (UOP) relative to the total estimated recoverable units of TCMs.

**19.2.9** **Others**

The model excludes project financing costs. No inflation is included in the model. The costs and long-term pricing are held constant over the LOM Plan.

**19.3** **Economic Analysis**

The assessment of reasonable prospects of economic extraction is supported by the positive NPV on an after-tax basis. A summary of key metrics from the financial model is provided in Table 19-2, with the annual detail of cash flows provided in Table 19-3.

**Table 19-2****Financial Model Key Metric Summary**

**19.3.1** **Sensitivities**

A sensitivity analysis was undertaken to examine the influence of changes to assumptions for metal prices, capital costs, and operating costs. The sensitivity analysis range (+/- 20 percent) was designed to capture the bounds of reasonable variability for each element analyzed.

The sensitivity of After-Tax NPV at an 8.0 percent discount rate as well as sensitivity of the After-Tax IRR are provided on Figures 19-1 and 19-2, respectively. The economic analysis is most sensitive to Sales Price and least sensitive to Capital Cost.

**19.4** **Cautionary Statement**

This economic analysis is based on an Initial Assessment that cannot be used as the basis for disclosure of Mineral Reserves. Unlike Mineral Reserves, Mineral Resources do not have demonstrated economic viability. The results are based entirely (i.e. 100 percent) on Inferred Mineral Resources, which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no demonstrated economic potential of the project if the Inferred Mineral Resources are excluded from the economic analysis. Future studies, including a Preliminary Feasibility Study based on Measured and Indicated Mineral Resources, would be required to establish Mineral Reserves.

**21.0** **Other Relevant Data and Information**

The Mineral Resource estimate disclosed in this TRS corresponds to the database cutoff date of June 30, 2025. During the period between the database cutoff and the report issue date, additional exploration data including drillhole sampling, and geological logging were conducted by Ramaco resulting in approximately 1,000 additional assays being collected with approximately 750 of these containing a Scandium assay. A portion of this subsequent information has been reviewed by the QPs on a preliminary basis; however, full validation, statistical reconciliation, and integration of the complete subsequent dataset into the resource model have not yet been completed as of the issue date of this report.

The QPs have considered whether the post-cutoff data, once fully validated and incorporated, could reasonably be expected to result in a material change to the Mineral Resource estimate disclosed herein. Because the Mineral Resource is reported exclusively in the Inferred category, the estimate already reflects the lower level of geological and grade continuity confidence appropriate to that classification, and the tonnage and grade ranges disclosed accommodate the limited drill density and inherent uncertainty associated with Inferred Resources. The preliminary review of the subsequent data indicates that the results are broadly consistent with the geological model, mineralization controls, and grade on which the current estimate is based, and the QPs have not identified any subsequent results that, individually or in aggregate, would be expected to alter the conclusions reached in this report.

While the QPs cannot definitively quantify the impact of the subsequent data until full validation and re-estimation work is completed, based on the preliminary review performed to date, no information has come to the attention of the QPs that would suggest a material change to the Mineral Resource estimate, the supporting geological interpretation, or any other disclosure contained in this TRS. A material change to the Mineral Resource estimate due to the subsequent data is not expected. The QPs confirm that the Mineral Resource estimate, the technical disclosures, and the conclusions presented in this report remain appropriate and supported by the data available as of the database cutoff date, and that this report has been prepared in accordance with the requirements of Regulation S-K 1300 (17 CFR § 229.1302) and the definitions and disclosure standards of Subpart 229.1300.

**22.0** **Interpretations and Conclusions**

**22.1** **Summary of Interpretations and Conclusions**

The Brook Mine hosts seven primary coal seams - the Dietz 1, Dietz 2, Dietz 3, Monarch, Upper Carney, Lower Carney, and Masters, plus seven unnamed seams below the Masters - together with adjacent carbonaceous claystone, clay, shale, and siltstone intervals that host the TCM mineralization described in this TRS. The coal seams are flat-lying, generally dipping to the southeast at one to four degrees. TCM mineralization is predominantly concentrated within five feet above and below the coal seam contacts, consistent with the depositional and hydrothermal enrichment mechanisms described in Section 6.

The geologic database consists of 615 drill holes in the database, of which 128 carry ICP-MS CMO assay data and comprising 5,903 individual sample analyses and drilled on a regular grid with approximate 1,000-foot spacing. Utilizing the geologic database, WEIR constructed a 50-foot × 50-foot × 0.5-foot block model using Datamine MineScape® software with Inverse Distance Squared grade interpolation and a ±2,800-foot lateral and ±5-foot vertical search ellipsoid. Block model validation against post-cutoff assay data (including a new drill hole approximately 250 feet from the nearest modeled samples) confirms that the model predicts TCM grade spikes at consistent elevations and of similar magnitude to measured values, supporting the interpreted grade continuity of the mineralization.

Based on the foregoing geological work, WEIR concludes that the interpreted stratigraphic framework is sufficiently continuous to support disclosure of Inferred Mineral Resources for both coal and TCMs in accordance with the definitions in Regulation S-K 1300. Although coal is an important associated commodity, WEIR’s interpretation is that the primary value of the Brook Mine lies in the critical minerals hosted immediately adjacent to the coal measures, specifically Scandium, Gallium, Germanium, Dysprosium, Neodymium, Praseodymium, and Terbium. The Inferred classification reflects a sample spacing wider than what WEIR considers necessary for an Indicated classification and the early stage of project definition consistent with an Initial Assessment; no portion of the TCM or coal tonnage has been classified as Measured or Indicated.

Ramaco controls sufficient mineral rights and associated surface access to support the Mineral Resources and the proposed mining operations described in this TRS. Specifically, Ramaco owns 93 percent of the mineral rights and controls the remaining 7 percent associated with the Brook Mine Mineral Resource estimate described in this TRS. Ramaco also owns 40 percent

​

​ ​

July 24, 2026 Page 175

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

of the surface rights associated with the Brook Mine Mineral Resource, with the balance controlled via agreements and leases. Areas where rights are limited, uncertain, or restricted have been removed from the resource estimate as appropriate: the Laya coal lease area is excluded because the lease does not expressly grant CMO extraction rights, and a portion of the Padlock property is excluded due to a restriction on surface mining.

Subject to the permit revisions and additional approvals discussed in Sections 3 and 17, the currently controlled land and mineral interests are considered adequate for the Initial Assessment mine plan and related project infrastructure. The active WDEQ/LQD surface coal mining permit (Permit No. 841-T1, 4,541 acres, issued July 7, 2020) provides a regulatory foundation for mining operations, however, a major permit revision will be required to authorize truck-and-shovel extraction of TCM-bearing material, extend mining depth to the Masters Seam and below, and accommodate the proposed processing and tailings facilities. Ramaco has not been cited for any violations of its existing permit requirements.

The Brook Mine is favorably situated with respect to infrastructure. The BNSF Railroad runs along the southern boundary of the permit area, providing rail access for thermal coal dispatch. Interstate 90 and US Highway 87 provide all-season highway access directly to the property. Electrical power is supplied by MDU; existing service is currently being upgraded for the pilot processing facility, with further expansion required for commercial operations. On-site wells supply potable and industrial water, with process makeup water estimated at approximately 0.6 tonnes per tonne of mill feed. The city of Sheridan, Wyoming (2025 population approximately 20,000) is located seven miles south of the property and provides access to labor, services, and supply chains. At full production, the Brook Mine and process plant will require approximately 190 personnel total with 70 in mining operations, 100 in mineral processing, and 20 in general and administrative functions. The staffing level is considered achievable given proximity to regional mining and industrial workforce centers.

Existing and planned infrastructure appears sufficient to support the proposed conventional truck-and-shovel surface mining operation and the planned hydrometallurgical process plant at a conceptual level. Thermal coal recovered in conjunction with TCM mining is expected to be sold as a ROM thermal product into local or regional markets, providing a practical and revenue-generating outlet for coal seam material that must be excavated to access the TCM-bearing horizons.

Metallurgical testwork completed to date indicates that the TCMs can be recovered using a multi-stage hydrometallurgical flowsheet supported by established unit operations widely used

​

in the mining industry. The conceptual flowsheet, developed through bench-scale testing at Hazen (eight months of testing through December 2025), process engineering by Fluor, and pilot plant engineering oversight by Hatch comprises: (1) feed handling and comminution using mineral sizers and an open-circuit ball mill to a target P80 of 200 µm; (2) pretreatment to enhance leach kinetics; (3) primary and secondary multi-stage leaching and filtration; (4) impurity removal via pH-adjustment precipitation and ion exchange; (5) rare earth separation via SX; and (6) parallel gallium and germanium circuits using established SX chemistry (Kelex 100 for Ga). Estimated TCM processing recoveries applied in the resource and economic models are: Dy₂O₃ 82%, Ga₂O₃ 67%, GeO₂ 94%, Nd₂O₃ 92%, Pr₆O₁₁ 92%, Sc₂O₃ 70%, and Tb₄O₇ 94%. The designed plant throughput is 2.6 million ROM tonnes per annum, with estimated installed power of 9.3 MW and process water makeup of approximately 0.6 tonnes per tonne of mill feed. Filtered (dry-stack) tailings management is planned; heap leaching is not proposed.

Results from the geometallurgical testwork program indicate a carbochlorination flowsheet may offer significant benefits to the hydrometallurgical process with solvent extraction to produce separated mixed rare earth oxides. Commercial carbochlorination is a high-temperature industrial process using carbon (coke, coal) to convert metal oxides (like rare earths, alumina, and titanium ores) into volatile chlorides and water-soluble metal chlorides. In the case of the Brook Mine, valuable volatilized critical minerals such as gallium, germanium, aluminum, and silica. This flowsheet may offer a more efficient extraction of valuable metals with simpler flows than traditional methods by recycling chlorine in the process. Carbochlorination is the dominant flowsheet used to produce titanium. In addition to an expanded suite of products versus a solvent extraction process, other potential benefits include ability to use Brook Mine mineralized coal as a reagent. In this process, recovery of rare earths and critical minerals from the coal may be possible. Rare earths could be solubilized by water in a carbochlorination flowsheet rather than more harsh reagents necessary in hydrometallurgical solvent extraction flowsheet.

Testwork to date has supported the conceptual flowsheet and process assumptions used in this Initial Assessment; however, additional bench-scale variability testing across all mineralized domains, optimization of reagent selection and dosing, extended pilot-plant campaigns, and product qualification testing are warranted to refine recoveries, reagent consumption rates, product specifications, and the design basis for future flowsheet updates. The expected TCM products are saleable critical mineral oxide products, and project value is dependent on continued demonstration of product quality, specification compliance, and market acceptance.

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

The Initial Assessment indicates that the Brook Mine can be evaluated on the basis of a conventional open-pit mining method using standard truck-and-shovel practices, with coal, TCM-bearing materials, and waste mined selectively in accordance with the conceptual LOM mine plan. The conceptual LOM plan, based on the revenue-factor 0.68 pit shell, covers 40 years of full-scale production, moving approximately 1.09 billion tonnes of total material at an average rate of approximately 27.2 Mtpa, delivering a steady-state TCM plant feed of approximately 2.63 Mtpa. Over the 40-year LOM Plan, approximately 293 million tonnes of TCM resources are mined, of which approximately 105.2 million tonnes is delivered to the process plant as plant feed; the balance is stockpiled as higher-grade (HG, ~10.8 Mt closing balance) and lower-grade (LG, ~177 Mt closing balance) material in mined-out pit areas for potential future processing. Within the LOM Plan footprint, approximately 45.4 million tonnes of in-situ coal resource is present, of which approximately 40.8 million tonnes is recovered as saleable ROM thermal coal product over the 40-year schedule, applying a 90 percent coal mining recovery factor consistent with PRB truck-and-shovel industry norms. The LOM Plan strip ratio averages approximately 2.2:1 on a combined waste-to- (coal + TCM product) basis. LOM Plan average metal head grades delivered to the process plant are approximately: Nd 48.3 g/t, Ga 23.4 g/t, Sc 21.1 g/t, Pr 12.3 g/t, Dy 7.5 g/t, Ge 3.6 g/t, and Tb 1.3 g/t.

Capital and operating cost estimates used in this TRS are conceptual and appropriate to an Initial Assessment stage. Total initial capital expenditure is estimated at $579 million, including $106 million of contingency (representing 25 percent of process plant direct and indirect costs), with an overall cost accuracy range of -30 percent to +50 percent. Pre-production capital is allocated over an assumed 30-month execution period. Life-of-mine total operating costs are estimated at approximately $87.70 per metric tonne of mill feed, incorporating mining, processing, dry-stack residue handling, and general and administrative costs as well as coal mining. The financial model is a constant-dollar DCF model structured on an annual basis over the 40-year LOM, excluding project financing costs. Applicable taxes include the Section 45X Advanced Manufacturing Production Tax Credit (applied as a 10 percent credit based on TCM mining and processing costs), Wyoming coal severance tax (6 percent of gross coal revenue), Sheridan County ad valorem tax (4 percent of gross coal revenue), TCM extractive taxes (4 percent of gross TCM revenue), and federal corporate income tax (21 percent). No state income tax applies in Wyoming; no TCM royalties are modeled, coal royalties have been modeled. The economic analysis presented in this TRS yields a positive after-tax NPV of $1,039 million at an 8 percent discount rate and an IRR of 28 percent showing robust project economics. This Initial Assessment is preliminary in nature, includes only Inferred Mineral Resources, and demonstrates reasonable prospects for

​

​ ​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

economic extraction of those Mineral Resources. There is no demonstrated economic potential of the project if the Inferred Mineral Resources are excluded from the economic analysis.

Overall, the QPs conclude that the Brook Mine warrants continued advancement through additional drilling, geologic refinement, metallurgical optimization, engineering, hydrologic and geotechnical studies, market development, and permitting work. The current work supports continued delineation and technical evaluation of both the TCM and coal mineralization and provides a reasonable conceptual basis for the Initial Assessment presented in this TRS. The geological, metallurgical, and economic results are consistent with a project meriting progression to the PFS level, at which point updated resource models, improved engineering designs, and additional metallurgical variability data are expected to reduce the material uncertainties identified herein. However, all Mineral Resources remain classified as Inferred, no Mineral Reserves have been estimated for the Brook Mine, and the findings of this Initial Assessment should not be construed as demonstrating economic viability.

**22.2** **Significant Risks and Uncertainties**

Risk, as defined for this study, is a hazard, condition, or event related to geology and Mineral Resources, mine operations and mineral processing, environmental and waste management issues, health and safety, marketing information, cost estimation, and the assumptions used in the economic analysis and general business issues that when taken individually, or in combination, have an adverse impact on Ramaco’s development of the Brook Mine. Risks can disrupt mine construction or operations, adversely affect mineral production and productivity, and result in increased operating cost and/or increased capital expenditures.

The Brook Mine is subject to risks and uncertainties typical of an early-stage mining project and additional risks associated with the unique nature of the TCM mineralization and proposed recovery process. Because the Initial Assessment is based entirely on Inferred Mineral Resources, the project is subject to a high degree of geological, technical, permitting, market, and execution risk. The principal risks are summarized in Table 22-1, as follows:

**Table 22-1****Brook Mine Risk Assessment Summary**

​

​ ​ ​ ​ ​

**Risk Area** ​ **Summary of Risk or Uncertainty** ​ **Potential Effect**

Geologic continuity and resource confidence ​ The current resource estimate is based on Inferred Mineral Resources and on an early-stage understanding of TCM continuity, faulting, seam correlations, and grade distribution. ​ Future drilling and modeling may materially change tonnage, grade, continuity, pit limits, and mine plans.

​

​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

**Risk Area** ​ **Summary of Risk or Uncertainty** ​ **Potential Effect**

Sampling and QA/QC limitations ​ Portions of the assay database rely on laboratory-internal QA/QC, and some supporting laboratory documentation and legacy records remain incomplete. ​ Additional verification may affect confidence in portions of the dataset and limit any future upgrade of resource classification until resolved. Unrecognized sampling and lab biases may be present that could impact the economic results.

Metallurgical performance ​ Metallurgical testing is preliminary and may not fully represent all mineralized domains, operating conditions, or full-scale performance. ​ Actual recoveries, reagent consumption, throughput, or product quality may differ from assumptions used in the Initial Assessment.

Process design and scale-up ​ The proposed TCM process plant and flowsheet remain conceptual and have not yet been demonstrated at commercial scale. ​ Capital costs, operating costs, recoveries, reliability, and schedule may differ materially from current assumptions.

Permitting and regulatory approvals ​ The existing permit is for coal mining and will require revision to include deeper seams, TCM extraction, processing facilities, and tailings-related infrastructure. ​ Project development could be delayed, modified, or constrained by permitting requirements, environmental studies, bonding, and agency approvals.

Hydrogeologic and geotechnical conditions ​ Additional data are required to support deeper mining, final pit design, groundwater management, and associated reclamation planning. ​ Mine design, dewatering requirements, slope design, sequencing, and costs may change as further studies are completed.

Property, rights, and encumbrances ​ Certain lease areas and surface-restricted areas are excluded, and other encumbrances and third-party rights exist across portions of the property. ​ Mine layout, access, or extraction sequence may be constrained and some mineralized areas may remain unavailable for development.

Commodity prices and marketability ​ Project economics are sensitive to assumptions for TCM pricing, market acceptance, and the realization of product specifications. ​ Lower prices or reduced marketability could materially reduce or eliminate reasonable prospects for economic extraction.

Staffing requirements ​ Availability of experienced labor may be limited in Sheridan and the surrounding areas. ​ Slower than anticipated hiring rates, or increased training requirements may slow productivity of initial operations. Effective recruiting, competitive compensation, and training programs will be needed.

Capital, operating cost, and productivity assumptions ​ The Initial Assessment relies on conceptual cost estimates and assumed mining and plant performance. ​ Adverse changes in costs, productivity, inflation, or scheduling could materially affect project outcomes.

Tax credits and legal framework<br>​ ​ Economic assumptions include consideration of currently available incentives and current regulatory conditions and their continuation. ​ Changes in tax policy, incentives, mining law, environmental law, or other regulations could materially affect project value and development timing.

​

In the opinion of the authors of this study, none of the identified risks and uncertainties individually prevent continued advancement of the Brook Mine at the Initial Assessment level. However, taken collectively, they are material to the future development of the project and reinforce the appropriateness of the current Inferred resource classification and the preliminary

nature of the economic analysis. Advancement of the Brook Mine will require additional technical work to reduce these uncertainties prior to any future study intended to support higher-confidence Mineral Resources or any declaration of Mineral Reserves.

**23.0** **Recommendations**

Based on the interpretations and conclusions presented in Section 22, it is recommended that Ramaco continue to advance the Brook Mine through a focused program of additional drilling, geological modeling, metallurgical testing, mine planning, geotechnical and hydrogeological work, environmental studies, and permitting support. The recommended work is intended to reduce the principal uncertainties identified in this TRS, improve confidence in the TCM and coal Mineral Resource estimates, support refinement of the conceptual mine and process designs, and provide the technical basis for a future study at a higher level of confidence. The recommendations below are consistent with the current status of the Brook Mine as an Initial Assessment based solely on Inferred Mineral Resources.

**23.1** **Recommended Work Program**

The next phase of work should be directed toward those activities most likely to improve geological confidence, reduce technical risk, and support refinement of the economic assumptions used in this Initial Assessment. The highest priorities are confirmation of structural and seam continuity, expansion and modernization of the QA/QC program, additional representative metallurgical and variability testing, refinement of mine and process design inputs, and advancement of permitting and environmental baseline work for the revised mine and process configuration. A listing of the relevant work areas, objective of studies, and relative priority are provided in Table 23-1 as follows:

**Table 23-1****Recommended Work Program Summary**

​

**Work Area** **Recommended Scope** **Objective** **Priority**

Geology and resource delineation Complete additional infill drilling, including the currently planned fence drilling, with emphasis on structural interpretation, seam correlations, and areas of lower sample density. Improve confidence in seam and TCM continuity, refine fault interpretation, and support potential future Mineral Resource confidence classification upgrades. High

Sampling, QA/QC, and data management Implement a fully externalized QA/QC program that includes blind certified reference materials, blanks, and duplicates inserted by Ramaco; resolve outstanding laboratory documentation items; continue database validation and audit trails. Increase confidence in assay accuracy and precision and remove limitations currently preventing consideration of higher-confidence classifications. High

Geostatistics and estimation methodology Use the planned closer-spaced drilling to complete geostatistical analyses, drill spacing studies, and estimation sensitivity reviews for the principal TCM domains and coal seams. Support a more rigorous basis for future Mineral Resource confidence classification and estimation methodology selection. High

Metallurgical and variability testing Expand bench-scale testing to include variability with samples across representative seams, lithologies, and grade ranges; confirm recoveries, reagent consumption, deleterious element response, and downstream product specifications. Reduce uncertainty in process performance and support refinement of the process flowsheet and economic assumptions. High

​

​

​

​ ​ ​

*Technical Report Summary* *Brook Mine - Initial Assessment**Prepared for Ramaco Resources, Inc.* ​

​

​

**Work Area** **Recommended Scope** **Objective** **Priority**

Process design and scale-up Advance the conceptual process design through additional engineering, mass balance refinement, equipment sizing, and design criteria development for major process areas and tailings-related infrastructure. Improve confidence in capital and operating cost estimates and support permitting of the processing facilities. High

Carbochlorination ​ Develop and execute a geometallurgical test program utilizing a carbochlorination process flowsheet. ​ Determine metallurgical response of TCM feed material under various operating conditions and determine the ability to recover additional TCMs from coal, and produce higher quality final products. ​ High

Mine planning Refine pit designs, sequencing, production schedules, haulage assumptions, and integration of coal and TCM extraction strategies using updated geology and engineering inputs. Improve mine plan realism and support future economic and environmental studies. High

Hydrogeology and geotechnical studies Continue groundwater monitoring, deeper seam hydrogeologic characterization, slope design studies, and supporting geotechnical assessments for final pit and facilities planning. Reduce uncertainty related to dewatering, pit slope design, mining below currently permitted horizons, and reclamation planning. High

Environmental and permitting Advance baseline studies and permit-support work required to revise the existing mine permit for deeper seams, TCM extraction, processing facilities, water management infrastructure, and tailings-related facilities. Support timely permitting and identify potential design or scheduling constraints at an earlier stage. High

Infrastructure and site layout Refine water, power, access, tailings, refuse, and plant site infrastructure layouts in conjunction with process and mine planning updates. Improve constructability, permitting readiness, and cost estimate reliability. Medium

Logistics study Study required material receiving/transfer/storage and associated loading and unloading requirements with potential and/or confirmed origin of reagent supply and turnaround times at the origin and Sheridan. Support more accurate design criteria and improved confidence in the process plant design and cost estimate. Medium

Markets and economic analysis Update product pricing assumptions, marketability assessments, operating and capital cost estimates, and economic sensitivities as additional technical information becomes available. Confirm whether reasonable prospects for economic extraction continue to be supported under updated assumptions. Medium

​

This work should be undertaken as an integrated program rather than as isolated technical tasks. Geological drilling, QA/QC improvements, and geostatistical analysis should proceed in parallel with metallurgical variability testing so that updated resource models, mine plans, and process assumptions can be developed on a consistent basis. Hydrogeologic, geotechnical, environmental, and permitting studies should likewise advance in coordination with mine and process design to ensure that future engineering reflects realistic permitting and operating constraints.

These recommendations are intended to reduce the material risks and uncertainties identified and to improve the technical basis for future decision-making. They should not be interpreted as demonstrating economic viability or supporting declaration of Mineral Reserves at this stage as that requires the application of modifying factors to Measured and Indicated Mineral Resources in at least a Preliminary Feasibility Study.

**23.2** **Implementation Considerations and Study Advancement**

Planned work scopes, contractors, timing, and internal procurement assumptions are likely to change as the project evolves. However, Ramaco maintains an internal budget to progress the Brook Mine through the Preliminary Feasibility Study phase where economic viability can be demonstrated and Mineral Reserves declared. A summary of this budget and the key work streams is provided in Table 23-2, as follows:
