Note 1 — Organization and Basis of Presentation

Noble Corporation plc, a public limited company incorporated under the laws of England and Wales (“Noble”, the “Company”, or “we”), is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. As of the filing date of this report, our fleet of 31 drilling rigs consisted of 25 floaters and 6 jackups.

We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist primarily of large, integrated, independent, and government-owned or controlled oil and gas companies throughout the world.

The accompanying unaudited condensed consolidated financial statements of Noble have been prepared pursuant to the rules and regulations of the US Securities and Exchange Commission (“SEC”) as they pertain to Quarterly Reports on Form 10-Q. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. The unaudited financial statements are prepared on a going concern basis and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the financial position and results of operations for the interim periods on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a recurring nature. The December 31, 2025, Condensed Consolidated Balance Sheet presented herein is derived from the December 31, 2025, audited consolidated financial statements. These interim financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2025, filed by Noble. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

Note 3 — Earnings (Loss) Per Share

The following table presents the computation of basic and diluted earnings (loss) per share:

Only those items having a dilutive impact on our basic earnings (loss) per share are included in diluted earnings (loss) per share. The following table displays the share-based instruments that have been excluded from diluted earnings (loss) per share since the effect would have been anti-dilutive:

(1) Represents the total number of warrants outstanding which did not have a dilutive effect. In periods where the warrants are determined to be dilutive, the number of shares which will be included in the computation of diluted shares is determined using the Treasury Stock Method, adjusted for mandatory exercise provisions under the warrant agreements, if applicable.

Share Capital

As of March 31, 2026, Noble had approximately 159.5 million Ordinary Shares outstanding as compared to approximately 158.9 million Ordinary Shares outstanding at December 31, 2025. In addition, as of March 31, 2026, 0.9 million Tranche 1 Warrants and 0.8 million Tranche 2 Warrants were outstanding and exercisable. Furthermore, new equity awards may be granted under the Noble Corporation plc 2022 Long-Term Incentive Plan, pursuant to which, up to 3.9 million new Ordinary Shares may be issued.

The declaration and payment of dividends require authorization of the Board of Directors, provided that such dividends on issued share capital may be paid only out of the Company’s “distributable reserves” as determined by reference to relevant statutory accounts in accordance with English law. The Company is not permitted to pay dividends out of share capital, which includes share premiums. The payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, the availability of sufficient distributable reserves, contractual and indenture restrictions, and other factors deemed relevant by our Board of Directors. During each of the quarters ended March 31, 2026 and 2025, we declared and paid a dividend of $0.50 per share.

Share Repurchases

Under English law, the Company is only permitted to purchase its own Ordinary Shares by way of an “off-market purchase” pursuant to a contract approved by shareholders (except where the purchase is for the purposes of, or pursuant to, any employees’ share scheme). Such purchases may be paid for either (i) out of the Company’s “distributable reserves” as determined by reference to relevant statutory accounts in accordance with English law or (ii) from the proceeds of a fresh

NOBLE CORPORATION plc AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unless otherwise indicated, dollar and share amounts in tables are in thousands, except per share data)

issue of shares made for the purpose of financing the purchase. On October 22, 2024, the Company’s Board of Directors authorized an increased share repurchase authorization of up to an additional $400.0 million and, at the 2025 annual general meeting of shareholders, shareholders approved the repurchase of up to 23,800,068 Ordinary Shares. The authorization by the Board of Directors has approximately $370.0 million remaining, does not have a fixed expiration, and may be modified, suspended, or discontinued at any time. None of the shareholder authorization to purchase up to 23,800,068 Ordinary Shares has yet been utilized and the authorization by shareholders expires on May 8, 2030 (subject to certain exceptions). The program does not obligate the Company to acquire any particular amount of Ordinary Shares. During the three months ended March 31, 2026 and 2025, the Company repurchased none and 0.7 million of the Company’s Ordinary Shares, respectively. All repurchased shares were subsequently cancelled, and the nominal value of the repurchased shares was transferred to the Capital Redemption reserve. Under this program, repurchases may be made from time to time using a variety of methods such as open market purchases and privately negotiated transactions, in compliance with relevant rules and regulations. In establishing this program, the Board considered the benefits to shareholders of providing the business with this additional capital allocation flexibility to promote long-term value for shareholders alongside other uses of capital.

Warrants

The tranche 1 warrants (the “Tranche 1 Warrants”) are exercisable for one Ordinary Share per warrant at an exercise price of $19.27 per warrant, the tranche 2 warrants (the “Tranche 2 Warrants”) are exercisable for one Ordinary Share per warrant at an exercise price of $23.13 per warrant, and the tranche 3 warrants (the “Tranche 3 Warrants”), which expired on February 4, 2026, were exercisable for one Ordinary Share per warrant at an exercise price of $124.40 per warrant.

Note 4 — Property and Equipment

Property and equipment, at cost, for Noble consisted of the following:

Capital additions, including capitalized interest, during the three months ended March 31, 2026 and 2025, totaled $137.3 million and $89.5 million, respectively.

During the first quarter of 2026, we sold the Noble Tom Prosser, Noble Mick O'Brien, Noble Regina Allen, Noble Resilient, and Noble Resolute for net proceeds of $346.7 million, resulting in a pre-tax gain of $89.5 million.

As of March 31, 2026, the Noble Resolve qualified as held for sale and was included in “Other assets” on our Consolidated Balance Sheet at its carrying value of $64.2 million.

Note 5 — Debt

Partial Redemption of Debt Principal

On March 27, 2026, we redeemed $55.0 million aggregate principal amount of our 8.500% Senior Secured Second Lien Notes due 2030 for $56.7 million, plus accrued interest, and recognized a gain of approximately $0.7 million.

Secured Revolving Credit Agreement

The revolving credit facility under the Amended and Restated Senior Secured Revolving Credit Agreement, dated April 18, 2023, and as amended on June 24, 2024, and on December 16, 2025 (the “2023 Revolving Credit Facility”), provides for commitments of $550.0 million with maturity in 2028. The guarantors under the 2023 Revolving Credit Facility are the same subsidiaries of Noble Finance II LLC, a wholly-owned, indirect subsidiary of Noble (“Noble Finance II”), that are or will be guarantors of the 2030 Notes (as defined below). As of March 31, 2026, we had no borrowings outstanding and $6.7 million of letters of credit issued under the 2023 Revolving Credit Facility.

(Unless otherwise indicated, dollar and share amounts in tables are in thousands, except per share data)

8.000% Senior Notes due 2030

In 2023, Noble Finance II, a wholly owned subsidiary of Noble, issued $600.0 million in aggregate principal amount of its 8.000% Senior Notes due 2030 (the “Initial 2030 Notes”). On August 22, 2024, Noble Finance II issued an additional $800.0 million in aggregate principal amount of its 8.000% Senior Notes due 2030 (the “Additional 2030 Notes” and, together with the Initial 2030 Notes, the “2030 Notes”) at a premium of 103% bringing the total outstanding principal amount to $1.4 billion. The 2030 Notes were issued pursuant to an indenture, dated as of April 18, 2023 (as supplemented or otherwise modified from time to time, the “Noble Indenture”), among Noble Finance II, the subsidiaries of Noble Finance II party thereto, as guarantors, and U.S. Bank Trust Company, National Association, as trustee, paying agent, and registrar.

The 2030 Notes are unconditionally guaranteed on a senior unsecured basis by the above guarantors and will be unconditionally guaranteed on the same basis by certain of Noble Finance II’s future subsidiaries that guarantee certain indebtedness of Noble Finance II and the above guarantors, including the 2023 Revolving Credit Facility.

The 2030 Notes will mature on April 15, 2030, and interest on the 2030 Notes is payable semi-annually in arrears on each April 15 and October 15, commencing October 15, 2023, to holders of record on the April 1 and October 1 immediately preceding the related interest payment date, at a rate of 8.000% per annum.

8.500% Senior Secured Second Lien Notes due 2030

In 2023, Diamond Foreign Asset Company and Diamond Finance, LLC (collectively referred to as the “Issuers”) issued $550.0 million aggregate principal amount of 8.500% Senior Secured Second Lien Notes due October 2030 (the “Diamond Second Lien Notes”) with interest payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2024. On March 27, 2026, Diamond Foreign Asset Company redeemed $55.0 million aggregate principal amount of its 8.500% Senior Secured Second Lien Notes due 2030 for $56.7 million bringing the total outstanding principal amount to $495.0 million. The Diamond Second Lien Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by Noble Offshore Drilling, Inc. (formerly known as Dolphin Merger Sub 2, Inc. and as successor by merger with Diamond Offshore Drilling, Inc.) (“NODI”) and each of its existing restricted subsidiaries (other than the Issuers) and by certain of NODI’s future restricted subsidiaries.

The Diamond Second Lien Notes obligate NODI and its subsidiaries to comply with an indenture dated as of September 21, 2023 (as supplemented and otherwise modified from time to time, the “Diamond Second Lien Indenture”), among the Issuers, NODI, certain of its subsidiaries party thereto, as guarantors, and HSBC Bank USA, National Association, as trustee and collateral agent. The Diamond Second Lien Indenture contains covenants that, among other things, restrict NODI’s ability and the ability of certain of its subsidiaries to: (i) incur additional debt and issue certain preferred stock; (ii) incur or create liens; (iii) make certain dividends, distributions, investments, and other restricted payments; (iv) sell or otherwise dispose of certain assets; (v) engage in certain transactions with affiliates; and (vi) merge, consolidate, amalgamate, or sell, transfer, lease, or otherwise dispose of all, or substantially all, of the assets of NODI and such subsidiaries taken as a whole. These covenants are subject to important exceptions and qualifications.

Fair Value of Debt

Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated fair value of our debt instruments was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar remaining maturities (Level 2 measurement). The fair value of the 2023 Revolving Credit Facility approximates its respective carrying amount as its interest rate is variable and reflective of market rates.

Note 6 — Revenue and Customers

Disaggregation of Revenue

The following table provides information about contract drilling services revenue by rig types:

Contract Balances

Accounts receivables are recognized when the right to the consideration becomes unconditional based upon contractual billing schedules. Payment terms on invoiced amounts are typically 30 to 60 days. Customer contract assets and liabilities generally consist of contract costs and deferred revenue resulting from past transactions related to the provision of services under contracts with customers. Current contract asset and liability balances are included in “Prepaid expenses and other current assets” and “Other current liabilities,” respectively, and noncurrent contract assets and liabilities are included in “Other assets” and “Other liabilities,” respectively, on our Condensed Consolidated Balance Sheets.

Certain direct and incremental costs incurred for upfront preparation, initial rig mobilization, and modifications are costs of fulfilling a contract and are recoverable. These recoverable costs are deferred and amortized ratably to contract drilling expense as services are rendered over the initial term of the related drilling contract. Costs incurred for the demobilization of rigs at contract completion are recognized as incurred during the demobilization process.

Certain of our contracts also include capital rig enhancements used to satisfy our performance obligations. Payments for these modifications are initially recognized as a contract liability and amortized ratably as contract drilling revenue over the initial term of the related drilling contract. The costs are capitalized in accordance with our existing property and equipment accounting policy and depreciated over the estimated useful life of the improvement.

Significant changes in the remaining performance obligation contract assets and the contract liabilities balances for the three months ended March 31, 2026 and 2025, are as follows:

Off-market Customer Contract Assets and Liabilities

Off-market customer contract assets and liabilities were recognized in connection with the merger, pursuant to a Business Combination Agreement, dated November 10, 2021, as amended, by and among Noble, Noble Finco Limited (n/k/a Noble Corporation plc), Noble Newco Sub Limited, the Drilling Company of 1972 A/S, a Danish public limited liability company (“Maersk Drilling”), and the other parties thereto (the “Business Combination with Maersk Drilling”) and the agreement and plan of merger, dated June 9, 2024, with Diamond Offshore Drilling, Inc. (“Diamond”), Dolphin Merger Sub 1, Inc., and Dolphin Merger Sub 2, Inc., under which Noble would acquire Diamond in a stock plus cash transaction (the “Diamond Transaction”), and are included in “Other assets” and “Noncurrent contract liabilities,” respectively.

In connection with the Business Combination with Maersk Drilling, the Company recognized additional fair value adjustments of $23.0 million. As of March 2025, these intangible assets were fully amortized as a reduction of contract drilling services revenue from October 3, 2022, through the remainder of the contracts.

NOBLE CORPORATION plc AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unless otherwise indicated, dollar and share amounts in tables are in thousands, except per share data)

In connection with the Business Combination with Maersk Drilling and the Diamond Transaction, the Company recognized fair value adjustments of $237.7 million and $27.7 million, respectively, related to certain unfavorable customer contracts acquired. As of June 2025, these liabilities were fully amortized as an increase to contract drilling services revenue from October 3, 2022, and September 4, 2024, respectively, through the remainder of the contracts.

Note 7 — Income Taxes

During the three months ended March 31, 2026, the Company recognized additional discrete deferred tax benefits of $16.6 million related to releases and adjustments of valuation allowance for deferred tax benefits primarily in Luxembourg and Switzerland.

During the three months ended March 31, 2025, the Company recognized additional discrete deferred tax benefits of $18.5 million related to releases and adjustments of valuation allowance for deferred tax benefits in Guyana, Nigeria, Switzerland, and Luxembourg.

In deriving the above net deferred tax benefits, the Company relied on sources of income attributable to the projected taxable income for the period covered by the Company’s relevant existing drilling contracts based on the assumption that the relevant rigs will be owned by the relevant rig owners during the relevant existing drilling contract periods. Given the mobile nature of the Company’s assets, we are not able to reasonably forecast the jurisdictions in which taxable income from future drilling contracts may arise. We also have limited objective positive evidence in historical periods. Accordingly, in determining the amount of additional deferred tax assets to recognize, we did not consider projected book income beyond the conclusion of existing drilling contracts. As new drilling contracts are executed or as current contracts are extended, we will reassess the amount of deferred tax assets that are realizable. Finally, once we have established sufficient objective positive evidence for historical periods, we may consider reliance on forecasted taxable income from future drilling contracts.

At March 31, 2026, the reserves for uncertain tax positions totaled $116.5 million (net of related tax benefits of $0.9 million). At December 31, 2025, the reserves for uncertain tax positions totaled $119.2 million (net of related tax benefits of $0.9 million).

During the three months ended March 31, 2026, our tax provision included tax benefits of $16.6 million related to adjustments to valuation allowance for deferred tax benefits primarily in Luxembourg and Switzerland. Such tax benefits were offset by tax effects of $23.5 million related to the gain on sale of operating assets and recurring quarterly accruals of $66.1 million mostly in Guyana, Luxembourg, Switzerland, and the United States.

Note 8 — Commitments and Contingencies

Tax Matters

Audit claims of approximately $374.1 million at March 31, 2026, attributable to income and other business taxes, remain outstanding and are under continued objection by Noble. Such audit claims are mostly attributable to Brazil and remain under continued monitoring and evaluation on a quarterly basis as facts change and as audits and/or litigation continue to progress. We intend to vigorously defend our reported positions and currently believe the ultimate resolution of the audit claims will not have a material adverse effect on our consolidated financial statements.

We operate in numerous countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe have a greater than 50% likelihood of being sustained upon challenge by a tax authority. We cannot predict nor provide assurance as to the ultimate outcome of any existing or future assessments.

Letters of Credit and Surety Bonds

As of March 31, 2026, we had $6.7 million of letters of credit issued under the 2023 Revolving Credit Facility and an additional $42.8 million in letters of credit and surety bonds issued under bilateral arrangements which guarantee our performance as it relates to our drilling contracts, contract bidding, tax appeals, customs duties, and other obligations in various jurisdictions. We expect to comply with the underlying performance requirements and we expect obligations under these letters of credit and surety bonds will not be called.

Other Contingencies

We are a defendant in certain other claims and litigation arising out of operations in the ordinary course of business, including personal injury claims, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations, or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.

Note 9 — Supplemental Financial Information

Condensed Consolidated Balance Sheets Information

Restricted cash

Noble’s restricted cash balance as of March 31, 2026, and December 31, 2025, was $3.9 million and $8.6 million, respectively. All restricted cash is recorded in “Prepaid expenses and other current assets.”

Leases

Our lease agreements are primarily for real estate, equipment, storage, dock space, and automobiles and are included within “Other assets”, “Other current liabilities”, and “Other liabilities” on our Condensed Consolidated Balance Sheets. In connection with the Diamond Transaction, the Company assumed several finance leases for well control equipment used on the drillships that included an option to purchase the leased equipment at the end of the respective lease term.

During the first quarter of 2026, Noble exercised the option to purchase the leased equipment and entered into a purchase and sale agreement with EFS BOP, LLC, as seller for the purchase of four blowout preventer (“BOP”) systems. The aggregate purchase price for the equipment is $73.0 million. As a result, two of the four BOP systems were purchased in March 2026 and were reclassified to “Property and equipment” from “Other assets” on our Condensed Consolidated Balance Sheet. The closings for the remaining two BOP systems are due to occur during the second and fourth quarters of 2026, respectively, consistent with the remaining lease term.

Supplemental balance sheet information related to finance leases was as follows:

Notes receivable

On December 8, 2025, Borr Drilling Limited ("Borr") and Noble entered into a Sale and Purchase Agreement (which was amended on January 5, 2026, the "SPA"), pursuant to which Borr agreed to buy and Noble has agreed to sell five jackup rigs (the "Purchased Rigs") for $360.0 million.

In relation to the SPA, Noble provided a $150.0 million loan to Borr (the "Loan"), with three out of the five Purchased Rigs (Noble Tom Prosser, Noble Regina Allen, and Noble Resilient) used as collateral. The Loan has the seniority of Subordinated Secured obligation and matures on January 7, 2032, with the interest rate of the Loan changing over time (ranging from 7.5% to 15.0%). Furthermore, the Loan can be prepaid at any time without premium or penalty, with certain provisions mandating prepayment. We initially recorded notes receivable equal to the fair value of the Loan estimated through the use of a discounted cash flow model.

The carrying value of the notes receivable as of March 31, 2026, was $148.8 million. The notes receivable are recorded in “Other assets.”

Executive Overview

Noble is a leading offshore drilling contractor for the oil and gas industry. As of the filing date of this Quarterly Report on Form 10-Q, Noble performs, through its subsidiaries, contract drilling services with a fleet of 31 drilling rigs, consisting of 25 floaters and 6 jackups (excluding certain rigs currently operating under a bareboat charter agreement), focused largely on ultra-deepwater and high-specification jackup drilling opportunities in both established and emerging regions worldwide. We typically employ each drilling unit under an individual contract, and many contracts are awarded based upon a competitive bidding process.

We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist primarily of large, integrated, independent and government-owned or controlled oil and gas companies throughout the world.

Market Outlook

In recent years, oil prices have generally remained at levels that are supportive of offshore exploration and development activity and global rig demand recovered to eclipse pre-pandemic levels, albeit with some moderation since early 2024, although, recently, the ongoing conflict in Iran has caused significant disruption in the normal flow of oil, refined petroleum products, and related commodities, with consequent price increases. Current demand and utilization levels are supported by the combination of the outlook for longer-term commodity prices, heightened focus on energy security, the capital intensity of depletion replacement, and relative attractiveness of offshore plays with respect to both cost and carbon emissions. The increase in global rig demand since 2021 has had a positive impact on dayrates for most rig classes, although dayrates have decreased moderately since recent highs in 2023 and 2024.

The global rig supply has come down from historic highs as Noble and other offshore drilling contractors have retired less capable and idle assets. Concurrently, the incoming supply of newbuild offshore drilling rigs has diminished materially, with very few newbuild rigs now remaining stranded in shipyards.

Although the market outlook in our business varies by geographical region and water depth and, despite recent volatility regarding the price of oil, we remain encouraged by the long-term outlook in the ultra-deepwater floater market. Our customers continue to focus on our highest specification floaters, which represents the majority of our floater fleet. Assuming current market fundamentals, continued customer prioritization towards these highest specification floaters could result in lower utilization for our lower specification drillships and our semi-submersibles. Demand for midwater semisubmersibles is primarily driven by brownfield activity in mature basins, especially in Northwest Europe, South America, and the Asia Pacific regions, where a generally stable level of baseload demand is supported by infield drilling and plug and abandonment requirements. Despite some recent contract suspensions in select jackup markets, we have also observed an overall demand increase in the global jackup market since 2020. While we remain encouraged about overall long-term rig demand, as evidenced by recent multi-year, multi-rig contracts that we have booked into backlog, the near-term outlook for both floaters and jackups over the next several quarters continues to present lingering utilization headwinds compared to 2023-2024 levels. Furthermore, economic uncertainty and increased volatility regarding commodity prices, arising from, among other things, the recent escalation of conflict in Iran, disrupted shipping channels, and elevated geopolitical tensions, collectively present potential for oil demand destruction and supply chain pressure.

Returning to the broader offshore drilling market, recent contract awards and open tenders show an increasing proportion of multi-year contracts, although a significant number of shorter-term commitments continue to be fixed as well. Longer-term contracts can generally provide economic efficiencies by reducing the number of rig contract start-ups, both with different customers and among different regions, which is expected to reduce incremental resources and costs. On the other hand, certain multi-year contracts that are scheduled to commence a year or longer into the future can present near-term utilization inefficiency due to challenges with filling interim availability on the assets.

The energy transition from hydrocarbons to renewables poses a challenge to the oil and gas sector and our market. Energy rebalancing trends sharply accelerated over the past decade as evidenced by promulgated or proposed government policies and commitments by many of our customers to further invest in sustainable energy sources, although this trend has moderated or even reversed in certain jurisdictions in more recent years with shifting political priorities. Our industry could be further challenged as resource holders and policy makers continue to evaluate and calibrate strategies and capital

flows to address global energy needs. Ultimately, however, there continues to be a global dependence on products made from hydrocarbons and on the combustion of hydrocarbons to provide reliable and affordable energy. Low-cost and low-emission barrels are expected to be the most attractive conventional source to meet energy needs both currently and in the future. Global energy demand is predicted to increase over the coming decades, and we expect that offshore oil and gas will continue to play an important and lasting role in meeting this demand.

Our cost profile remains sensitive to global labor market conditions, capital intensive repair and maintenance scopes on our rigs, global trade and sanctions regimes, including the impacts of new or increased tariffs or trade wars, and geopolitical crises (including the recent escalation of conflict in Iran) and their respective regional and global ramifications. Each of these factors has the potential to adversely impact our ability to conduct our day-to-day operations and manage costs with uncertainty related to trade policy and tariffs also having the ability to negatively impact rig demand.

Contract Drilling Services Backlog

We maintain a backlog of commitments for contract drilling services. Our contract drilling services backlog reflects estimated future revenues attributable to signed drilling contracts. As of March 31, 2026, contract drilling services backlog totaled approximately $7.2 billion.

We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for such unit by the number of days remaining in the period, and include certain assumptions based on the terms of certain contractual arrangements, discussed in the notes to the table below. The reported contract drilling services backlog does not include amounts representing revenues for mobilization, demobilization, and contract preparation, which are not expected to be significant to our contract drilling services revenues, amounts constituting reimbursables from customers, or amounts attributable to uncommitted option periods under drilling contracts or letters of intent.

The table below presents the amount of our contract drilling services backlog as of March 31, 2026, and the percent of available operating days committed for the periods indicated:

(1) Represents a nine-month period beginning April 1, 2026.

(2) Noble entered into a multi-year Commercial Enabling Agreement (the “CEA”) with ExxonMobil in February 2020. Under the CEA, dayrates for the rigs are repriced on January 1 and July 1 each year to the projected market rate at the time the new rate goes into effect, subject to a scale-based discount and a performance bonus that appropriately aligns the interests of Noble and ExxonMobil. Under the CEA, the above table includes awarded and remaining current contract term to February 18, 2029, related to each of the four following rigs: the Noble Tom Madden, Noble Bob Douglas, Noble Don Taylor, and Noble Sam Croft. Under the CEA, ExxonMobil may reassign remaining contract term among rigs, subject to maintaining certain minimum contract term on the rig from which term is removed.

(3) Assuming approximately 40% of available performance revenue realized on a combined basis under certain long-term contracts with Shell plc (US Gulf) and TotalEnergies (Suriname).

(4) In 2022, Noble renewed its five-year Framework Agreement with Aker BP for the provision of ultra-harsh environment jackup rigs, the Noble Integrator and Noble Invincible, for activities in offshore Norway. Under this Framework Agreement, different rate structures apply reflecting different operating modes, agreed incentive schemes, and adjustments for operating expenses. Rate structures are adjusted annually to reflect market conditions.

(5) Percent of available days committed is calculated by dividing the total number of days our rigs are operating under contract for such period by the product of the number of our rigs, including cold stacked rigs (i.e., idle without a contract, have reduced or no crew, or are not actively marketed in present market conditions), and the number of calendar days in such period.

(6) The above table includes approximately $15.8 million of backlog associated with the Noble Resolve, held for sale as of March 31, 2026, pertaining to the agreement with Ocean Oilfield Drilling.

The amount of actual revenues earned and the actual periods during which revenues are earned may be materially different than the backlog amounts and backlog periods presented in the table above due to various factors, including, but not limited to, shipyard and maintenance projects, unplanned downtime, the operation of market benchmarks for dayrate resets, achievement of bonuses, weather conditions, reduced standby or mobilization rates, and other factors that result in applicable dayrates lower than the full contractual operating dayrate. In addition, amounts included in the backlog may change because drilling contracts may be varied or modified according to their terms or by mutual consent, or customers may exercise early termination rights contained in some of our drilling contracts or decline to enter into a drilling contract after executing a letter of intent. As a result, our backlog as of any particular date may not be indicative of our actual operating results for the periods for which the backlog is calculated. See Part I, Item 1A, “Risk Factors – Risks Related to Our Business and Operations – Our current backlog of contract drilling revenue may not be ultimately realized” in our Form 10-K.

As of March 31, 2026, ExxonMobil, Shell, BP, TotalEnergies, and Aker BP represented approximately 21.1%, 19.1%, 14.4%, 12.5%, and 11.1% of our backlog, respectively.

Results of Operations

Results for the Three Months Ended March 31, 2026 and 2025

Net income for the three months ended March 31, 2026 (the “current quarter”), was $120.7 million, or $0.75 per diluted share, on operating revenues of $785.7 million compared to net income for the three months ended March 31, 2025, of $108.3 million, or $0.67 per diluted share, on operating revenues of $874.5 million.

Key Operating Metrics

Operating results for our contract drilling services segment are dependent on three primary metrics: operating days, dayrates, and operating costs. We also track rig utilization, which is a function of operating days and the number of rigs in our fleet. For more information on operating costs, see “Contract Drilling Services” below.

The following table presents the average rig utilization, operating days, and average dayrates for our rig fleet for the periods indicated:

(1) We define utilization for a specific period as the total number of days our rigs are operating under contract, divided by the product of the total number of our rigs, including cold stacked rigs, and the number of calendar days in such period. Information reflects our policy of reporting on the basis of the number of available rigs in our fleet.

(2) An operating day is defined as a calendar day during which a rig operated under a drilling contract. We define average dayrates as revenue from contract drilling services earned per operating day. Average dayrates have not been adjusted for the non-cash amortization related to favorable and unfavorable customer contract intangibles.

Contract Drilling Services

The following table presents the operating results for our contract drilling services segment for the periods indicated (dollars in thousands):

(1) We record reimbursements from customers for out-of-pocket expenses as operating revenues and the related direct costs as operating expenses. Changes in the amount of these reimbursables generally do not have a material effect on our financial position, results of operations, or cash flows.

The following table provides information about contract drilling revenue and costs by rig types (dollars in millions except average dayrates):

Contract Drilling Services Revenues

Floaters. During the first quarter of 2026, floaters generated revenue of $620.6 million, as compared to $693.4 million in the first quarter of 2025. The decrease in revenue was mainly attributable to $93.9 million from rigs with net changes in operating days. This decrease was partly offset by $28.4 million from an increase in average dayrates in the current period. Additionally, floater revenue from net non-cash amortization related to off-market customer contract assets and liabilities decreased $7.4 million in the current period.

Jackups. During the first quarter of 2026, jackups generated revenue of $122.0 million, as compared to $139.0 million in the first quarter of 2025. The decrease in revenue was mainly attributable to $23.4 million from rigs with net changes in operating days primarily as a result of divestitures during the current period. This decrease was partly offset by $6.7 million from an increase in average dayrates in the current period.

Operating Costs and Expenses

Floaters. During the first quarter of 2026, total contract drilling services costs related to floaters was $362.6 million, as compared to $391.6 million in the first quarter 2025. The primary drivers of this decrease were $13.5 million in rental equipment, $10.5 million in repairs and maintenance, $4.7 million in regulatory inspections, and $4.4 million in non-labor costs, operations support costs, and other costs across the fleet. Further, there was a decrease of $5.8 million related to certain rigs sold or no longer operated by Noble. These decreases were partially offset by increases of $6.5 million in mobilization and $3.4 million in fuel.

Jackups. During the first quarter of 2026, total contract drilling services cost related to jackups was $87.5 million, as compared to $70.5 million in the first quarter 2025. The primary drivers of this increase were $1.8 million in labor and $25.5 million in non-labor costs, operations support costs, and other costs across the fleet principally due to insurance proceeds received during the prior year quarter. These increases were partially offset by a decrease of $4.9 million in mobilization. Further, there was a decrease of $5.4 million related to certain rigs sold or no longer operated by Noble.

Depreciation and amortization. Depreciation and amortization totaled $137.3 million and $143.1 million during the first quarter of 2026 and 2025, respectively. Depreciation and amortization decreased primarily due to divestitures during the current period as well as the timing of capital additions that were placed in service as compared to retirements among the periods.

General and administrative. General and administrative expenses totaled $30.0 million and $35.2 million during the first quarter of 2026 and 2025, respectively. The decrease was primarily due to reductions within certain corporate charges such as professional fees, corporate leases, and employee-related costs.

Merger and integration costs. Noble incurred $2.6 million and $14.9 million of merger and integration costs during the first quarter of 2026 and 2025, respectively. In the first quarter of 2026 and 2025, all and the majority of costs incurred, respectively, directly related to the agreement and plan of merger, dated June 9, 2024, with Diamond Offshore Drilling, Inc. (“Diamond”), Dolphin Merger Sub 1, Inc., and Dolphin Merger Sub 2, Inc., under which Noble would acquire Diamond in a

stock plus cash transaction (the “Diamond Transaction”). In both periods, such costs related primarily to professional fees and certain integration-related activities.

(Gain) loss on sale of operating assets, net. During the first quarter of 2026, we sold the Noble Tom Prosser, Noble Mick O'Brien, Noble Regina Allen, Noble Resilient, and Noble Resolute, resulting in a pre-tax gain of $89.5 million.

Other Income and Expenses

Interest expense, net of amounts capitalized. Interest expense totaled $40.6 million and $40.5 million during the first quarter of 2026 and 2025, respectively. Interest expense in each period primarily related to our 2030 Notes as well as the Diamond Second Lien Notes (as defined below). For additional information, see “Note 5 — Debt” to our unaudited condensed consolidated financial statements.

Interest income and other, net. Noble recognized interest and other income of $8.2 million and $1.8 million during the first quarter of 2026 and 2025, respectively. The current period includes $3.4 million of interest income from the seller notes received from the sale of jackup rigs to Borr Drilling Limited. For additional information, see “Note 9 — Supplemental Financial Information—Notes receivable” to our unaudited condensed consolidated financial statements.

Income tax benefit (provision). Noble recorded an income tax provision of $72.9 million and $40.4 million during the first quarter of 2026 and 2025, respectively.

During the first quarter of 2026, our tax provision included tax benefits of $16.6 million related to adjustments to valuation allowance for deferred tax benefits primarily in Luxembourg and Switzerland. Such tax benefits were offset by tax effects of $23.5 million related to the gain on sale of operating assets and recurring quarterly accruals of $66.1 million mostly in Guyana, Luxembourg, Switzerland, and the United States.

During the first quarter of 2025, our tax provision included tax benefits of $56.6 million related to releases of valuation allowance for deferred tax benefits primarily in Luxembourg and a net tax benefit of $10.0 million related to uncertain tax position movements. Such tax benefits were offset by tax expenses related to recurring quarterly accruals of $107.0 million mostly in Guyana, Luxembourg, Switzerland, and the United States.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal source of capital in the current period was cash generated from operating activities. Cash on hand during the current period was primarily used for the following:

• normal recurring operating expenses;
• capital expenditures;
• fees and expenses related to merger and integration costs;
• dividend payments; and
• certain contractual cash obligations and commitments.

Our anticipated cash flow needs, both in the short term and long term, may also include share repurchases, repurchases, redemptions, or repayments of debt and interest.

We currently expect to fund our cash flow needs with cash generated by our operations, cash on hand, proceeds from sales of assets, or borrowings under the 2023 Revolving Credit Facility (as defined below), and we believe this will provide us with sufficient liquidity to fund our cash flow needs over the next 12 months. Subject to market conditions and other factors, we may also issue equity or long-term debt securities to fund our cash flow needs and for other purposes. We have been incurring expenses and capital costs related to an incident regarding one floater. These incurred costs exceeded the applicable deductible. We have received partial insurance recoveries for these claims and we continue to seek insurance recoveries for the remainder of the incurred and anticipated costs.

Net cash provided by operating activities was $273.3 million and $271.1 million for the three months ended March 31, 2026 and 2025, respectively. The increase in net cash provided by operating activities for the three months ended March 31, 2026, was primarily attributable to improvements in cash flows from operating liabilities driven by more efficient working capital management. We had working capital of $715.4 million at March 31, 2026, and $512.6 million at December 31, 2025.

Net cash provided by investing activities was $102.5 million for the three months ended March 31, 2026, and net cash used in investing activities was $98.1 million for the three months ended March 31, 2025. The increase in net cash provided by investing activities for the three months ended March 31, 2026, was attributable to the disposal of rigs during the current period. Otherwise, investing activities in the current period consisted of capital expenditures on routine projects associated with overhauls and upgrades on various rigs.

Net cash used in financing activities was $189.2 million and $116.5 million for the three months ended March 31, 2026 and 2025, respectively. During the three months ended March 31, 2026, we repaid $56.7 million of debt, made dividend payments to our shareholders of $83.7 million, made finance lease payments of $41.8 million, and paid $9.7 million in taxes withheld on vested employee share-based compensation awards. During the three months ended March 31, 2025, we repurchased 0.7 million of our Ordinary Shares for a total of $20.0 million, made dividend payments to our shareholders of $81.4 million, made finance lease payments of $6.0 million, and paid $9.1 million in taxes withheld on vested employee share-based compensation awards.

At March 31, 2026, we had a total contract drilling services backlog of approximately $7.2 billion, which includes a commitment of 67% of available days for the remainder of 2026. For additional information regarding our backlog, see “Contract Drilling Services Backlog.”

Capital Expenditures

Capital expenditures were $103.9 million and $113.5 million for the three months ended March 31, 2026 and 2025, respectively.

Capital expenditures in each period consisted of outlays for sustaining capital, major projects, including subsea and other related projects, capital spares, rebillable capital and contract modifications, and capitalized interest.

Our total capital expenditures estimate for the year ending December 31, 2026, is expected to range between $615.0 million and $665.0 million. We expect to fund these capital expenditures with cash generated by our operations and cash on hand.

From time to time we consider possible projects and certain events may occur that would require expenditures that are not included in our capital budget, and such unbudgeted expenditures could be significant. This includes additional capital expenditures to upgrade rigs for specific customer requirements or contracts. The total amount of capital that we ultimately spend is partly dependent on broader market conditions, the actual level of current and expected contracting activity, as well as costs related to satisfying regulatory requirements. Given many of our capital related projects can take considerable time to complete, the actual costs and timing of expenditures may vary materially from estimates based on various factors, many of which are out of our control. In addition, while liquidity and preservation of capital remains our top priority, we will continue to evaluate acquisitions of drilling units from time to time.

Amended and Restated Senior Secured Revolving Credit Agreement

The revolving credit facility under the Amended and Restated Senior Secured Revolving Credit Agreement, dated April 18, 2023, and as amended on June 24, 2024, and on December 16, 2025 (the “2023 Revolving Credit Facility”), provides for commitments of $550.0 million with maturity in April 2028. The guarantors under the 2023 Revolving Credit Facility are the same subsidiaries of Noble Finance II LLC, a wholly-owned, indirect subsidiary of Noble (“Noble Finance II”), that are or will be guarantors of the 2030 Notes (as defined below).

As of March 31, 2026, we had no borrowings outstanding and $6.7 million of letters of credit issued under the 2023 Revolving Credit Facility and an additional $42.8 million in letters of credit and surety bonds issued under bilateral arrangements. For additional information about the 2023 Revolving Credit Facility, see “Note 5 — Debt” to our unaudited condensed consolidated financial statements.

8.000% Senior Notes due 2030

In 2023, Noble Finance II, a wholly owned subsidiary of Noble, issued $600.0 million in aggregate principal amount of its 8.000% Senior Notes due 2030 (the “Initial 2030 Notes”). The Initial 2030 Notes were issued pursuant to an indenture, dated April 18, 2023 (as supplemented or otherwise modified from time to time, the “Noble Indenture”), among Noble Finance II, the subsidiaries of Noble Finance II party thereto, as guarantors (the “Guarantors”), and U.S. Bank Trust Company, National Association, as trustee. In August 2024, Noble Finance II issued an additional $800.0 million in aggregate principal amount of its 8.000% Senior Notes due 2030 (the “Additional 2030 Notes” and, together with the Initial 2030 Notes, the “2030 Notes”) at a premium of 103% bringing the total outstanding principal amount to $1.4 billion. The Additional 2030 Notes

were issued pursuant to the Noble Indenture and the net proceeds from the offering of the Additional 2030 Notes were primarily used to fund the cash consideration in the Diamond Transaction and to pay any premiums, fees, and expenses related to the issuance of the Additional 2030 Notes. As of March 31, 2026, we had outstanding $1.4 billion aggregate principal amount of our 2030 Notes. For additional information about the 2030 Notes, see “Note 5 — Debt” to our unaudited condensed consolidated financial statements.

8.500% Senior Secured Second Lien Notes due 2030

In connection with the agreement and plan of merger, dated June 9, 2024, with Diamond Offshore Drilling, Inc. (“Diamond”), Dolphin Merger Sub 1, Inc., and Dolphin Merger Sub 2, Inc., under which Noble would acquire Diamond in a stock plus cash transaction (the “Diamond Transaction”), the Company assumed $550.0 million aggregate principal amount of 8.500% Senior Secured Second Lien Notes due October 2030 (the “Diamond Second Lien Notes”) issued pursuant to an indenture, dated as of September 21, 2023 (as supplemented and otherwise modified from time to time, the “Diamond Second Lien Indenture”), among Diamond Foreign Asset Company and Diamond Finance, LLC, as issuers, Diamond Offshore Drilling, Inc., the other guarantors party thereto and HSBC Bank USA, National Association, as trustee and as collateral agent. On March 27, 2026, Diamond Foreign Asset Company redeemed $55.0 million aggregate principal amount of our 8.500% Senior Secured Second Lien Notes due 2030 for $56.7 million. As of March 31, 2026, we had outstanding $495.0 million aggregate principal amount of our Diamond Second Lien Notes. For additional information about the Diamond Second Lien Notes, see “Note 5 — Debt” to our unaudited condensed consolidated financial statements.

Dividends

On April 27, 2026, Noble’s Board of Directors declared an interim quarterly cash dividend on our Ordinary Shares of $0.50 per share. This dividend will be paid on June 25, 2026, to shareholders of record at close of business on June 4, 2026.

The declaration and payment of dividends require authorization of the Board of Directors, provided that such dividends on issued share capital may be paid only out of the Company’s “distributable reserves” as determined by reference to relevant statutory accounts in accordance with English law. The Company is not permitted to pay dividends out of share capital, which includes share premiums. The payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, the availability of sufficient distributable reserves, contractual and indenture restrictions, and other factors deemed relevant by our Board of Directors. During each of the quarters ended March 31, 2026 and 2025, we declared and paid a dividend of $0.50 per share.

Share Repurchases

Under English law, the Company is only permitted to purchase its own Ordinary Shares by way of an “off-market purchase” pursuant to a contract approved by shareholders (except where the purchase is for the purposes of, or pursuant to, any employees’ share scheme). Such purchases may be paid for either (i) out of the Company’s “distributable reserves” as determined by reference to relevant statutory accounts in accordance with English law or (ii) from the proceeds of a fresh issue of shares made for the purpose of financing the purchase. On October 22, 2024, the Company’s Board of Directors authorized an increased share repurchase authorization of up to an additional $400.0 million and, at the 2025 annual general meeting of shareholders, shareholders approved the repurchase of up to 23,800,068 Ordinary Shares. The authorization by the Board of Directors has approximately $370.0 million remaining, does not have a fixed expiration, and may be modified, suspended, or discontinued at any time. None of the shareholder authorization to purchase up to 23,800,068 Ordinary Shares has yet been utilized and the authorization by shareholders expires on May 8, 2030 (subject to certain exceptions). The program does not obligate the Company to acquire any particular amount of Ordinary Shares. During the three months ended March 31, 2026 and 2025, the Company repurchased none and 0.7 million of the Company’s Ordinary Shares, respectively. All repurchased shares were subsequently cancelled, and the nominal value of the repurchased shares was transferred to the Capital Redemption reserve. Under this program, repurchases may be made from time to time using a variety of methods such as open market purchases and privately negotiated transactions, in compliance with relevant rules and regulations. In establishing this program, the Board considered the benefits to shareholders of providing the business with this additional capital allocation flexibility to promote long-term value for shareholders alongside other uses of capital.

Condensed Consolidating Financial Information

The Noble Indenture contains a covenant that requires Noble Finance II to furnish to holders of the 2030 Notes certain financial information relating to Noble Finance II and its restricted subsidiaries. The Diamond Second Lien Indenture contains a covenant that requires Noble Offshore Drilling, Inc. (formerly known as Dolphin Merger Sub 2, Inc. and as

successor by merger with Diamond Offshore Drilling, Inc.) (“NODI”) to furnish to holders of the Diamond Second Lien Notes certain financial information relating to NODI and its subsidiaries.

The summarized financial information below reflects combined accounts of Noble Finance II, NODI, and all other subsidiaries of Noble. The financial information is presented on a combined basis and intercompany balances and transactions between entities have been eliminated.

Critical Accounting Estimates

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States, which require us to make estimates that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from our estimates and assumptions and any such differences could be material to our consolidated financial statements. Some of our significant accounting policies involve critical accounting estimates because

they are particularly dependent on estimates and assumptions made by Noble about matters that are inherently uncertain. We disclose our significant accounting policies in “Note 1— Organization and Significant Accounting Policies” to our audited consolidated financial statements included in Part II, Item 8 of our Form 10-K.

For information about our critical accounting policies and estimates, see Part II, Item 7, “Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” in our Form 10-K. As of March 31, 2026, there have been no material changes to the judgments, assumptions, and estimates upon which our critical accounting policies and estimates are based.

See Part I, Item 1, Financial Statements, “Note 2 — Accounting Pronouncements,” to the unaudited condensed consolidated financial statements for a description of the recent accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There has been no significant change in our exposure to market risk when compared to those disclosed in Part II, Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” in our Form 10-K.

Item 4. Controls and Procedures

Conclusions Regarding Disclosure Controls and Procedures

Robert W. Eifler, President and Chief Executive Officer (Principal Executive Officer) of Noble, and Richard B. Barker, Executive Vice President and Chief Financial Officer (Principal Financial Officer) of Noble, have evaluated the disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”)) of Noble as of the end of the period covered by this report. On the basis of this evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that Noble’s disclosure controls and procedures were effective as of March 31, 2026. Noble’s disclosure controls and procedures are designed to ensure that information required to be disclosed by Noble in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including its Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in Noble’s internal control over financial reporting that occurred during the quarter ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting of Noble.

Limitations on the Effectiveness of Controls

Internal control over financial reporting includes the controls themselves, monitoring (including internal auditing practices), and actions taken to correct deficiencies as identified. There are inherent limitations to the effectiveness of internal control over financial reporting, however well designed, including the possibility of human error and the possible circumvention or overriding of controls. The design of an internal control system is also based in part upon assumptions and judgments made by management about the likelihood of future events, and there can be no assurance that an internal control will be effective under all potential future conditions. As a result, even an effective system of internal controls can provide no more than reasonable assurance with respect to the fair presentation of financial statements and the processes under which they were prepared.
