1.Organization and Principles of Consolidation

As used in this document, the terms “Partnership,” “Sunoco,” “we,” “us” or “our” should be understood to refer to Sunoco LP and its consolidated subsidiaries, unless the context clearly indicates otherwise.

We are a Delaware master limited partnership. We are managed by our General Partner, which is owned by Energy Transfer. As of March 31, 2026, Energy Transfer and its subsidiaries owned 100% of the membership interest our General Partner, 28,463,967 of our common units and all of our IDRs. In addition, Energy Transfer controls SunocoCorp, which owns all of the outstanding Class D Units and currently holds the rights to appoint and remove members of our General Partner.

We are primarily engaged in energy infrastructure and distribution of motor fuels across 32 countries and territories in North America, the Greater Caribbean and Europe. Our midstream operations include an extensive network of over 14,000 miles of pipeline and over 160 terminals. Our fuel distribution operations distribute over 15 billion gallons annually to approximately 11,000 Sunoco and partner branded locations, as well as independent dealers and commercial customers.

The consolidated financial statements include Sunoco LP, a publicly traded Delaware limited partnership, and its wholly owned subsidiaries. In the opinion of the Partnership’s management, such financial information reflects all adjustments necessary for a fair presentation of the financial position and the results of operations for such interim periods in accordance with GAAP. All significant intercompany accounts and transactions have been eliminated in consolidation.

The operations of certain pipelines and terminals in which we own an undivided interest are proportionately consolidated in the accompanying consolidated financial statements.

2.Summary of Significant Accounting Policies

Interim Financial Statements

The accompanying interim consolidated financial statements have been prepared in accordance with GAAP. Pursuant to Regulation S-X, certain information and disclosures normally included in the annual consolidated financial statements have been condensed or omitted. The interim consolidated financial statements and notes included herein should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 19, 2026.

Significant Accounting Policies

As of March 31, 2026, there have been no changes in the Partnership's significant accounting policies from those described in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 19, 2026.

Motor Fuel and Sales Taxes

Certain motor fuel and sales taxes are collected from customers and remitted to governmental agencies either directly by the Partnership or through suppliers. The Partnership’s accounting policy for wholesale direct sales to dealers, distributors and commercial customers is to exclude the collected motor fuel tax from sales and cost of sales.

For retail locations where the Partnership holds inventory, including commission agent locations, motor fuel sales and motor fuel cost of sales include motor fuel taxes. Such amounts were $185 million and $29 million for the three months ended March 31, 2026 and 2025, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in our consolidated statements of operations.

Recent Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40). ASU 2024-03 requires disclosure of specified information about certain costs and expenses in the notes to the consolidated financial statements. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within annual periods beginning after December 15, 2027, with early adoption permitted. ASU 2024-03 is to be applied on a prospective basis, with retrospective application permitted. We are currently evaluating the impact, if any, of ASU 2024-03 on our consolidated financial statements and related disclosures.

3.Acquisitions

TanQuid Acquisition

On January 16, 2026, the Partnership completed the previously announced acquisition of TanQuid for €206 million ($239 million) and assumed debt with a fair value of €298 million ($346 million). TanQuid owns and operates 15 fuel terminals in Germany and one fuel terminal in Poland. The transaction was funded using cash on hand and amounts available under the Partnership's Credit Facility.

The acquisition was recorded using the acquisition method of accounting which requires, among other things, that assets and liabilities assumed be recognized on the balance sheet at their estimated fair values as of the date of acquisition, with any excess purchase price over the fair value of net assets acquired recorded to goodwill. Management, with the assistance of a third-party valuation specialist, determined the fair value of assets and liabilities as of the date of the acquisition. Determining the fair value involves the use of management's judgment as well as the use of significant estimates and assumptions.

As of the date these financial statements were issued, management and the third-party valuation specialist continue to evaluate certain assumptions, which could result in a change to the allocation of the fair value among reporting units or between line items on the consolidated balance sheet, potentially impacting deferred tax balances and/or goodwill.

The following table summarizes the preliminary allocation of the purchase price among assets acquired and liabilities assumed.

Other Acquisitions

In the first quarter of 2026, the Partnership completed other acquisitions for total cash consideration of approximately $50 million, plus working capital. These transactions were accounted for as asset acquisitions.

4.Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, demand deposits and short-term investments with original maturities of three months or less.

The net change in operating assets and liabilities, net of effects of acquisitions and divestitures, included in cash flows from operating activities is comprised as follows:

Non-cash investing and financing activities and supplemental cash flow information:

5.Accounts Receivable, net

Accounts receivable, net, consisted of the following:

6.Inventories, net

Fuel inventories included balances stated at the lower of cost or market using the LIFO method. As of March 31, 2026 and December 31, 2025, the Partnership’s fuel inventory balance included lower of cost or market reserves of $1 million and $472 million, respectively. For the three months ended March 31, 2026 and 2025, the Partnership's cost of sales included favorable LIFO inventory valuation adjustments of $444 million and $61 million, respectively, which increased net income.

Inventories, net, consisted of the following:

During the three months ended March 31, 2026, the Partnership reduced its overall fuel inventories, resulting in a LIFO liquidation. Based on the assumed impact to cost of sales if the liquidated inventories had been replaced, the effect of the LIFO liquidation was an increase of $102 million to pre-tax income, or $0.54 per common unit (excluding any income tax impact or any assumed changes to distributions). Interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs; consequently, these interim estimates are subject to changes during the remainder of the year that could impact the final year-end inventory levels or valuation.

Certain of the Partnership’s fuel inventories in the Caribbean are stated at the lower of cost or market using the first-in, first-out method, under which the cost of fuel sold consists of older acquisition costs, including transportation and storage costs. These FIFO method inventories totaled $165 million and $88 million as of March 31, 2026 and December 31, 2025, respectively.

7.Investments in Unconsolidated Affiliates

In March 2026, the Partnership redeemed Parkland's remaining senior notes.

GoZone Bonds

NuStar Logistics' obligations include revenue bonds issued by the Parish of St. James, Louisiana pursuant to the Gulf Opportunity Zone Act of 2005 (the “GoZone Bonds”).

As reflected in the table below, the holders of the Series 2008, Series 2010B and Series 2011 GoZone Bonds are required to tender their bonds at the applicable mandatory purchase date in exchange for 100% of the principal plus accrued and unpaid interest, after which these bonds may be remarketed with a new interest rate established. Each of the Series 2010 and Series 2010A GoZone Bonds is subject to redemption on or after June 1, 2030 by the Parish of St. James, at Sunoco's option, in whole or in part, at a redemption price of 100% of the principal amount to be redeemed plus accrued and unpaid interest. Interest on the GoZone Bonds is payable semi-annually on June 1 and December 1 of each year.

The following table summarizes the GoZone Bonds outstanding as of March 31, 2026:

NuStar Logistics’ agreements with the Parish of St. James related to the GoZone Bonds contain: (i) customary restrictive covenants that limit the ability of NuStar Logistics and its subsidiaries to, among other things, create liens, enter into certain sale leaseback transactions, and engage in certain consolidations, mergers or asset sales; and (ii) a repurchase provision which provides that if Sunoco undergoes a change of control that is followed by a ratings decline that occurs within 60 days of the change of control, then each holder may require the trustee, with funds provided by NuStar Logistics, to repurchase all or a portion of that holder’s GoZone Bonds at a price equal to 101% of the aggregate principal amount repurchased, plus any accrued and unpaid interest. The Partnership and certain of its subsidiaries are guarantors to the agreements related to the GoZone Bonds.

Credit Facility

The Partnership's $2.50 billion Credit Facility matures on June 17, 2030, which date may be extended in accordance with the terms of the Credit Facility. The Credit Facility can be increased from time to time upon Sunoco's written request, subject to certain conditions, up to an aggregate amount of $3.50 billion. As of March 31, 2026, we had $125 million outstanding borrowings on the Credit Facility, and $151 million in standby letters of credit were outstanding. The unused availability on the Credit Facility as of March 31, 2026 was $2.22 billion. The weighted average interest rate on the total amount outstanding as of March 31, 2026 was 5.52%. The Partnership was in compliance with all financial covenants as of March 31, 2026. The Partnership's net leverage ratio was 3.98 to 1.00 at March 31, 2026.

Receivables Financing Agreement

Upon the closing of the NuStar Acquisition, the commitments under NuStar’s receivables financing agreement were reduced to zero during a suspension period, for which the period end has not been determined. As of March 31, 2026, this facility had no outstanding borrowings.

We also have agreements with subsidiaries of Energy Transfer and our unconsolidated affiliates for the purchase and sale of fuel. Additionally, under our Partnership Agreement, our General Partner does not receive a management fee or other compensation for its role as our general partner. However, our General Partner is reimbursed for all expenses incurred on our behalf. These expenses include shared service fees, as well as all other expenses necessary or appropriate to the conduct of our business that are allocable to us, as provided for in our Partnership Agreement. There is no cap on the amount that may be paid or reimbursed to our General Partner.

Costs to Obtain or Fulfill a Contract

The Partnership recognized amortization on capitalized costs incurred to obtain contracts of $17 million and $9 million for the three months ended March 31, 2026 and 2025, respectively.

13.Commitments and Contingencies

Litigation and Contingencies

We may, from time to time, be involved in litigation and claims arising out of our operations in the normal course of business. In the ordinary course of business, we are sometimes threatened with or named as a defendant in various lawsuits seeking actual and punitive damages for personal injury and property damage. We maintain liability insurance with insurers in amounts and with coverage and deductibles management believes are reasonable and prudent, and which are generally accepted in the industry. However, there can be no assurance that the levels of insurance protection currently in effect will continue to be available at reasonable prices or that such levels will remain adequate to protect us from material expenses related to personal injury or property damage in the future. In addition, various regulatory agencies such as tax authorities, environmental agencies, or other such agencies may perform audits or reviews to ensure proper compliance with regulations. We are not fully insured for any claims that may arise from these various agencies and there can be no assurance that any claims arising from these activities would not have an adverse, material effect on our consolidated financial statements.

Environmental Remediation

Sunoco is subject to various federal, state, provincial and local environmental laws and regulations and makes financial expenditures in order to comply with regulations governing its operations adopted by federal, state, provincial and local regulatory agencies. Pursuant to the Resource Conservation and Recovery Act of 1976 (“RCRA”), as amended, the United States Environmental Protection Agency has established a comprehensive regulatory program for the detection, prevention, investigation and cleanup of leaking underground storage tanks. State, provincial or local agencies are often delegated the responsibility for

implementing the federal program or developing and implementing equivalent state or local regulations. Additionally, with respect to the Burnaby Refinery, the federal Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations impose technical standards for design, installation, operation and removal of federally regulated tanks.

Federal and state regulations require us to provide and maintain evidence that we are taking financial responsibility for corrective action and compensating third parties in the event of a release from our underground storage tank systems, pipelines and terminals. In order to comply with these requirements, we have historically obtained private insurance in the states in which we operate. These policies provide protection from third-party liability claims. During 2026, our coverage was $15 million per occurrence and in the aggregate. Our sites continue to be covered by these policies.

We are currently involved in the investigation and remediation of contamination at motor fuel storage and gasoline store sites where releases of regulated substances have been detected. We accrue for anticipated future costs and the related probable state reimbursement amounts for remediation activities. The table below reflects recorded estimated undiscounted liabilities for these sites which are classified as accrued expenses, other current liabilities and other non-current liabilities.

New York Motor Fuel Excise Tax Audit

New York State issued a motor fuel excise tax assessment to Sunoco, LLC, a wholly owned subsidiary of the Partnership, in the amount of approximately $20 million, exclusive of penalties and interest, for the periods of March 2017 through May 2020. Sunoco, LLC filed an appeal with the New York State Division of Tax Appeals challenging the assessment. Sunoco, LLC cannot predict the outcome of this matter at this time.

14.Equity

As of March 31, 2026, Energy Transfer and its subsidiaries owned 28,463,967 of our common units and the public owned 108,430,787 of our common units. As of March 31, 2026, our wholly owned subsidiaries owned all of the 16,410,780 Class C units representing limited partner interests in the Partnership. In connection with the Parkland Acquisition, Sunoco issued to SunocoCorp 51,517,198 Class D Units which are economically equivalent to Sunoco's publicly traded common units (the “Class D Units”).

Sunoco Common Units

The change in our outstanding common units for the three months ended March 31, 2026 was as follows:

Class C Units

The Partnership has outstanding an aggregate of 16,410,780 Class C Units, all of which are held by wholly owned subsidiaries of the Partnership.

Class C Units (i) are not convertible or exchangeable into Common Units or any other units of the Partnership and are non-redeemable; (ii) are entitled to receive distributions of available cash of the Partnership (other than available cash derived from or attributable to any distribution received by the Partnership from Sunoco Retail, the proceeds of any sale of the membership interests of Sunoco Retail, or any interest or principal payments received by the Partnership with respect to indebtedness of Sunoco Retail or its subsidiaries) at a fixed rate equal to $0.8682 per quarter for each Class C Unit outstanding; (iii) do not have the right to vote on any matter except as otherwise required by any non-waivable provision of law; (iv) are not allocated any items of income, gain, loss, deduction or credit attributable to the Partnership’s ownership of, or sale or other disposition of, the membership interests of Sunoco Retail, or the Partnership’s ownership of any indebtedness of Sunoco Retail or any of its subsidiaries (“Sunoco Retail Items”); (v) will be allocated gross income (other than from Sunoco Retail Items) in an amount equal to the cash distributed to the holders of Class C Units and (vi) will be allocated depreciation, amortization and cost recovery deductions as if the Class C Units were Common Units and 1% of certain allocations of net termination gain (other than from Sunoco Retail Items).

Pursuant to the terms described above, these distributions do not have an impact on the Partnership’s consolidated cash flows and as such, are excluded from total cash distributions and allocation of limited partners’ interest in net income.

Class D Units

The Partnership has outstanding an aggregate of 51,517,198 Class D Units, which were issued in connection with the Parkland Acquisition in October 2025 and are held by SunocoCorp.

Class D Units (i) except as required by law and in addition to the voting rights established in the Partnership Agreement, are entitled to vote; (ii) shall represent limited partnership interests and common unit interests in the Partnership and shall be economically equivalent to other Partnership common units and no distribution may be made in respect of the Partnership’s common units unless an equal distribution is simultaneously made on the Class D Units; and (iii) provide dividend equalization rights for the period beginning on October 31, 2025 and ending December 31, 2027 (the “Equalization Period”), the Partnership shall ensure that SunocoCorp shall have cash necessary and sufficient to pay distributions on each SunocoCorp common unit for each quarter during the Equalization Period in an amount equal to 100% of the distributions paid by the Partnership on each Sunoco common unit during such quarter.

Preferred Units

In September 2025, the Partnership closed a private offering of 1.5 million of its 7.875% Series A Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Units (the “Series A Preferred Units”) at an offering price of $1,000 per unit. The Partnership received net proceeds of approximately $1.47 billion from the sale of the Series A Preferred Units after deducting the initial purchasers' discount and other estimated offering expenses. The Partnership used the net proceeds from this private offering (i) on the closing date of the Parkland Acquisition, to fund a portion of the cash consideration for the Parkland Acquisition, and (ii) prior to the closing date of the Parkland Acquisition, to temporarily reduce the borrowings outstanding under the Partnership's Credit Facility and to pay interest and fees in connection therewith.

Cash Distributions

Our Partnership Agreement sets forth the calculation used to determine the amount and priority of cash distributions that the common unitholders receive.

Cash distributions declared and/or paid with respect to Sunoco common units and Class D Units subsequent to December 31, 2025 were as follows:

Cash distributions with respect to our Series A Preferred Units were as follows:

Accumulated Other Comprehensive Loss

The following table presents the components of AOCI, net of tax:

15.Segment Reporting

Description of Segments

Our consolidated financial statements reflect four reportable segments: Fuel Distribution, Pipeline Systems, Terminals and Refinery.

Fuel Distribution. Our Fuel Distribution segment supplies motor fuel to independently-operated dealer stations, distributors, commission agents and other consumers. Also included in our Fuel Distribution segment is lease income from properties that we lease or sublease, as well as the Partnership’s credit card services, franchise royalties and retail operations in North America and the Greater Caribbean.

Pipeline Systems. Our Pipeline Systems segment includes an integrated pipeline and terminal network comprised of approximately 6,000 miles of refined product pipeline (including the pipeline of J.C. Nolan), approximately 6,000 miles of crude oil pipeline (including the pipelines of ET-S Permian), approximately 2,000 miles of ammonia pipeline and 69 terminals.

Terminals. Our Terminals segment is composed of four transmix processing facilities and 99 refined product terminals (18 in Europe, six in Hawaii, nine in Canada, 13 in the Greater Caribbean and 53 in the continental United States).

Refinery. Our Refinery segment includes the Burnaby Refinery, which was acquired in the Parkland Acquisition, with an operational capacity of approximately 55,000 barrels per day. The refinery consumes primarily sweet conventional crude oil and sweet synthetic crude oil to produce gasoline, diesel and jet fuel among other products.

Segment Operating Results

We report Adjusted EBITDA by segment as a measure of segment performance. We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation, amortization and accretion expense, non-cash compensation expense, gains and losses on disposal of asset, non-cash impairment charges, losses on extinguishment of debt, unrealized gains and losses on commodity derivatives, inventory valuation adjustments, certain foreign currency transaction gains and losses and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations. Inventory valuation adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory; these amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.

The following tables present financial information by segment for the three months ended March 31, 2026 and 2025:

(1) Other by segment includes Adjusted EBITDA from unconsolidated affiliates, unrealized gains and losses on commodity derivatives, inventory valuation adjustments and other less significant items, as applicable.

16.Net Income per Common Unit

A reconciliation of the numerators and denominators of the basic and diluted per unit computations is as follows:

17.Derivatives

Our subsidiaries hold working inventories of refined petroleum products, renewable fuels, gasoline blendstocks and transmix in storage. While in storage, volatility in the market price of stored motor fuel could adversely impact the price at which we can later sell the motor fuel. However, we may use futures, forwards and other derivative instruments (collectively, “positions”) to hedge a variety of price risks relating to deviations in that inventory from a target base operating level established by management. Derivative instruments utilized consist primarily of exchange-traded futures contracts traded on the New York Mercantile Exchange, Chicago Mercantile Exchange and Intercontinental Exchange, as well as over-the-counter transactions (including swap agreements) entered into with established financial institutions and other credit-approved energy companies. While these derivative instruments represent economic hedges, they are not designated as hedges for accounting purposes. We may also engage in controlled trading in accordance with specific parameters set forth in a written risk management policy.

On a consolidated basis, the Partnership had derivative positions on 2.8 million barrels with an aggregate unrealized loss of $76 million at March 31, 2026.

The following table summarizes the location and amounts recognized in our consolidated statements of operations with respect to our derivative financial instruments:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

(Tabular dollar amounts, except per gallon data, are in millions)

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and notes to consolidated financial statements included elsewhere in this report. Additional discussion and analysis related to the Partnership is contained in our Annual Report on Form 10-K, including the audited consolidated financial statements for the fiscal year ended December 31, 2025 included therein.

Adjusted EBITDA is a non-GAAP financial measure of performance that has limitations and should not be considered as a substitute for net income or other GAAP measures. Please see “Key Measure Used to Evaluate and Assess Our Business” below for a discussion of our use of Adjusted EBITDA in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and a reconciliation to net income for the periods presented.

Overview

As used in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, the terms “Partnership,” “we,” “us” or “our” should be understood to refer to Sunoco LP and its consolidated subsidiaries, unless the context clearly indicates otherwise.

We are a Delaware master limited partnership primarily engaged in energy infrastructure and distribution of motor fuels across 32 countries and territories in North America, the Greater Caribbean and Europe. Our midstream operations include an extensive network of over 14,000 miles of pipeline and over 160 terminals. Our fuel distribution operations distribute over 15 billion gallons annually to approximately 11,000 Sunoco and partner branded locations, as well as independent dealers and commercial customers.

Recent Developments

TanQuid Acquisition

On January 16, 2026, the Partnership completed the previously announced acquisition of TanQuid for €206 million ($239 million ) and assumed debt with a fair value of €298 million ($346 million as of January 16, 2026). TanQuid owns and operates 15 fuel terminals in Germany and one fuel terminal in Poland. The transaction was funded using cash on hand and amounts available under the Partnership's Credit Facility.

Other Acquisitions

In the first quarter of 2026, the Partnership completed other acquisitions for total cash consideration of approximately $50 million, plus working capital. These transactions were accounted for as asset acquisitions.

Regulatory Update

OECD Pillar Two Global Minimum Tax

The acquisition of Parkland brought Sunoco into the scope of the Pillar Two global minimum tax regime. Several jurisdictions in which Sunoco now operates have enacted legislation implementing the Organization for Economic Co-operation and Development (“OECD”) Pillar Two global minimum tax framework. These rules generally impose a 15% minimum top-up tax on the profits of large multinational enterprises. Sunoco estimates its Pillar Two global minimum tax expense to be immaterial in 2026 and has not accrued any current tax expense related to Pillar Two during the three months ended March 31, 2026.

On January 5, 2026, the OECD released new guidance that provides relief for U.S. parented multinationals and establishes a side-by-side framework for the U.S. tax system to coexist with Pillar Two global minimum tax. Effective for fiscal years beginning on or after January 1, 2026, U.S. parented multinationals would be exempt from the main charging provisions of Pillar Two. Sunoco will continue to estimate and potentially accrue Pillar Two global minimum tax until the relevant jurisdictions in which Sunoco operates enact the side-by-side framework into law.

Interstate Common Carrier Regulation

In December 2020, the FERC issued an order setting the indexed rate at PPI-FG plus 0.78% during the five-year period commencing July 1, 2021 and ending June 30, 2026. The FERC received requests for rehearing of its December 17, 2020 order and on January 20, 2022, granted rehearing and modified the oil index. Specifically, for the five-year period commencing July 1, 2021 and ending June 30, 2026, FERC-regulated liquids pipelines charging indexed rates were permitted to adjust their indexed ceilings annually by PPI-FG minus 0.21%. The FERC directed liquids pipelines to recompute their ceiling levels for July 1, 2021 through June 30, 2022, as well as the ceiling levels for the period July 1, 2022 through June 30, 2023, based on the new index level. Where an oil pipeline’s filed rates exceeded its ceiling levels, the FERC ordered such oil pipelines to reduce the rate to bring it into compliance with the recomputed ceiling level to be effective March 1, 2022. Some parties sought rehearing of the January 20, 2022 order with the FERC, which was denied by the FERC on May 6, 2022. Certain parties appealed the January 20 and May 6 orders. On July 26, 2024, the D.C. Circuit ruled in LEPA v. FERC that the FERC violated the Administrative Procedure Act because the January 20, 2022 order modified the index without following notice and comment. As a result, the D.C. Circuit vacated the January 20, 2022 order and on September 17, 2024, the FERC reinstated the index level established by its original December 17, 2020 order, directed pipelines to file an informational filing to show their recomputed ceiling levels reflecting the reinstated index level and stated that pipelines could file to prospectively increase their indexed rates to their recomputed levels. On October 17, 2024, the FERC issued a Supplemental Notice of Proposed Rulemaking (“Supplemental NOPR”) that proposed a reduction to the then- effective index by one percent.

On November 20, 2025, the FERC withdrew the Supplemental NOPR and confirmed that the PPI-FG-0.78% index established in its December 17, 2020 order will remain in effect through June 30, 2026. On the same day, the FERC issued an Order Denying Rehearing of the Reinstatement Order and Granting Remedial Relief (“Remedial Relief Order”), which granted remedial relief to liquids pipelines for the period of March 1, 2022 to September 17, 2024 (the “Locked-In Period”), when the lower index was effective under the order vacated by the D.C. Circuit in LEPA v. FERC, but only if such pipelines charged the maximum rate allowed under the applicable index ceiling during the relevant time period. Parties have since filed requests for clarification or rehearing, as well as court appeals, to determine whether pipelines may recover rate differences in other scenarios. Those requests and appeals remain pending.

Also on November 20, 2025, the FERC issued a Notice of Proposed Rulemaking on the 2026 Five-Year Oil Pipeline Index (“2026 Index NOPR”), proposing to use the Producer Price Index for Finished Goods (PPI-FG) minus 1.42% as the index level beginning July 1, 2026 to June 30, 2031. The NOPR proceeded through the standard notice-and-comment process, with comments submitted in late 2025 and early 2026, and remains pending final Commission action.

On December 18, 2025, the FERC issued an Order Denying Petition for Emergency Relief (“Emergency Relief Order Denial”), which denied a petition requesting emergency relief from invoices issued by a liquid pipeline company to recover amounts of indexed rates for the Locked-In Period and explained that, consistent with the Remedial Relief Order, pipelines that charged the maximum rates permitted under the FERC’s now-vacated January 20, 2022 rehearing order during the Locked-In Period may invoice shippers to recover the amounts that would have been chargeable under the December 17, 2020 order.

In January 2026, multiple shippers have filed petitions for review at the D.C. Circuit challenging the FERC’s November 20, 2025 orders, including, the (i) Remedial Relief Order, (ii) Order Terminating Supplemental NOPR, and (iii) Emergency Relief Order Denial. These appeals are pending.

Separately, on December 15, 2022, the FERC issued a Proposed Policy Statement on Oil Pipeline Affiliate Committed Service, which addresses whether a contract for committed transportation service complies with the Interstate Commerce Act (“ICA”) where the only shipper to obtain the committed service is an affiliate of the regulated entity. If adopted, the proposed policy statement would create a rebuttable presumption that affiliate contracts are unduly discriminatory and not just and reasonable in

certain circumstances and require a pipeline to produce additional evidentiary support for affiliate contracts rates and terms. This follows a trend of increased scrutiny by the FERC on affiliated contracts across all industries regulated by the FERC. The FERC has taken no further action on the proposed policy statement.

Regulation of Intrastate Crude Oil and Products Pipelines

In addition to federally regulated body oversight, various states, including Colorado, Kansas, Louisiana, North Dakota and Texas, maintain commissions focused on the rates and practices of common carrier pipelines offering services within their borders. Although the applicable state statutes and regulations vary, they generally require that intrastate pipelines publish tariffs setting forth all rates, rules and regulations applying to intrastate service, and generally require that pipeline rates and practices be just, reasonable and nondiscriminatory.

Shippers may challenge tariff rates, rules and regulations on our pipelines. In most instances, state commissions have not initiated investigations of the rates or practices of pipelines in the absence of shipper complaints. There are no pending challenges or complaints regarding our tariffs or tariff rates.

In addition, as noted above, the rates, terms and conditions for shipments of crude oil or petroleum products on Sunoco’s pipelines could be subject to regulation by the FERC under the ICA and the Energy Policy Act of 1992 (“EPAct of 1992”) if the crude oil or petroleum products are transported in interstate or foreign commerce whether by its pipelines or other means of transportation. Since Sunoco does not control the entire transportation path of all crude oil or petroleum products shipped on our pipelines, FERC regulation could be triggered by our customers’ transportation decisions.

Regulation of Interstate Ammonia Pipelines

Our ammonia pipeline is subject to regulation by the Surface Transportation Board (the “STB”) pursuant to the ICA applicable to such pipelines (which differs from the ICA applicable to interstate liquids pipelines). Under that regulation, the ammonia pipeline’s rates, classifications, rules and practices related to the interstate transportation of anhydrous ammonia must be reasonable and, in providing interstate transportation, the ammonia pipeline may not subject a person, place, port or type of traffic to unreasonable discrimination. Similar to the crude and refined products pipelines, the rates for transportation services on the ammonia pipeline are required to be in a tariff which is posted publicly on Sunoco’s website, however, that tariff is not required to be on file with the STB. The STB does not prescribe an indexing approach similar to the EPAct of 1992 but rates under the STB must be reasonable and the pipeline may not subject a person, place, port or type of traffic to unreasonable discrimination.

Key Measure Used to Evaluate and Assess Our Business

Adjusted EBITDA, as used throughout this document, is defined as net income before net interest expense, income tax expense, depreciation, amortization and accretion expense, non-cash compensation expense, gains and losses on disposal of asset, non-cash impairment charges, losses on extinguishment of debt, unrealized gains and losses on commodity derivatives, inventory valuation adjustments, certain foreign currency transaction gains and losses and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations. Inventory valuation adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory; these amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.

Adjusted EBITDA is a non-GAAP financial measure. For a reconciliation of Adjusted EBITDA to net income, which is the most directly comparable financial measure calculated and presented in accordance with GAAP, read “Key Operating Metrics and Results of Operations” below.

We believe Adjusted EBITDA is useful to investors in evaluating our operating performance because:

• Adjusted EBITDA is used as a performance measure under our Credit Facility;
• securities analysts and other interested parties use Adjusted EBITDA as a measure of financial performance; and
• our management uses Adjusted EBITDA for internal planning purposes, including aspects of our consolidated operating budget and capital expenditures.

Adjusted EBITDA is not a recognized term under GAAP and does not purport to be an alternative to net income as a measure of operating performance. Adjusted EBITDA has limitations as an analytical tool, and one should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations include:

• it does not reflect interest expense or the cash requirements necessary to service interest or principal payments on our Credit Facility or senior notes;
• although depreciation, amortization and accretion are non-cash charges, the assets being depreciated, amortized and accreted will often have to be replaced in the future, and Adjusted EBITDA does not reflect cash requirements for such replacements; and
• as not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies.

Adjusted EBITDA reflects amounts for the unconsolidated affiliates based on the same recognition and measurement methods used to record equity in earnings of unconsolidated affiliates. Adjusted EBITDA related to unconsolidated affiliates excludes the same items with respect to the unconsolidated affiliates as those excluded from the calculation of Adjusted EBITDA, such as interest, taxes, depreciation, amortization, accretion and other non-cash items. Although these amounts are excluded from Adjusted EBITDA related to unconsolidated affiliates, such exclusion should not be understood to imply that we have control over the operations and resulting revenues and expenses of such affiliates. Sunoco does not control its unconsolidated affiliates; therefore, Sunoco does not control the earnings or cash flows of such affiliates. The use of Adjusted EBITDA or Adjusted EBITDA related to unconsolidated affiliates as an analytical tool should be limited accordingly.

Results of Operations

Consolidated Results

Net Income. For the three months ended March 31, 2026 compared to the same period last year, net income increased by $437 million, or approximately 211%, primarily due to higher Segment Adjusted EBITDA from multiple segments, with the most significant increases driven by the Parkland Acquisition and other acquisitions; these increases were partially offset by increases in depreciation, amortization and accretion and interest expense. These increases and decreases are discussed further below.

Adjusted EBITDA (consolidated). For the three months ended March 31, 2026 compared to the same period last year, Adjusted EBITDA increased primarily due to the Parkland Acquisition and other acquisitions.

Additional information on changes impacting net income and comprehensive income (loss) and Adjusted EBITDA for the three months ended March 31, 2026 compared to the same period last year is available below and in “Segment Operating Results.”

Depreciation, Amortization and Accretion. For the three months ended March 31, 2026 compared to the same period last year, depreciation, amortization and accretion increased primarily due to additional depreciation and amortization from assets recently placed in service and from recent acquisitions.

Interest Expense, net. For the three months ended March 31, 2026 compared to the same period last year, interest expense increased primarily due to an increase in average total long-term debt, including debt assumed in the Parkland Acquisition.

Unrealized (Gains) Losses on Commodity Derivatives. The unrealized gains and losses on our commodity derivatives represent the changes in fair value of our commodity derivatives. The change in unrealized gains and losses between periods is impacted by the notional amounts and commodity price changes on our commodity derivatives. Additional information on commodity derivatives is included in “Item 3. Quantitative and Qualitative Disclosures about Market Risk” below.

Inventory Valuation Adjustments. Inventory valuation adjustments represent changes in lower of cost or market reserves using the LIFO method on the Partnership’s inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period. For the three months ended March 31, 2026 and 2025, the Partnership's cost of sales included favorable LIFO inventory valuation adjustments of $444 million and $61 million, respectively, which increased net income.

Adjusted EBITDA Related to Unconsolidated Affiliates and Equity in Earnings of Unconsolidated Affiliates. See additional information in “Supplemental Information on Unconsolidated Affiliates” and “Segment Operating Results.”

Income Tax Expense (Benefit). For the three months ended March 31, 2026 compared to the same period last year, income tax expense increased primarily due to increased corporate earnings from recent acquisitions.

Supplemental Information on Unconsolidated Affiliates

The following table presents financial information related to unconsolidated affiliates:

(1) These amounts represent our proportionate share of the Adjusted EBITDA of our unconsolidated affiliates and are based on our equity in earnings or losses of our unconsolidated affiliates adjusted for our proportionate share of the unconsolidated affiliates’ interest, depreciation, amortization, accretion, non-cash items and taxes.

Segment Operating Results

We evaluate segment performance based on Segment Adjusted EBITDA, which we believe is an important performance measure of the core profitability of our operations. This measure represents the basis of our internal financial reporting and is one of the performance measures used by senior management in deciding how to allocate capital resources among business segments.

The following tables identify the components of Segment Adjusted EBITDA, which is calculated as follows:

• Segment profit, operating expenses and selling, general and administrative expenses. These amounts represent the amounts included in our consolidated financial statements that are attributable to each segment.
• Adjusted EBITDA related to unconsolidated affiliates. Adjusted EBITDA related to unconsolidated affiliates excludes the same items with respect to the unconsolidated affiliates as those excluded from the calculation of Segment Adjusted EBITDA, such as interest, taxes, depreciation, amortization, accretion and other non-cash items. Although these amounts are excluded from Adjusted EBITDA related to unconsolidated affiliates, such exclusion should not be understood to imply that we have control over the operations and resulting revenues and expenses of such affiliates. We do not control our unconsolidated affiliates; therefore, we do not control the earnings or cash flows of such affiliates.

The following analysis of segment operating results includes a measure of segment profit. Segment profit is a non-GAAP financial measure and is presented herein to assist in the analysis of segment operating results and particularly to facilitate an understanding of the impacts that changes in sales revenues have on the segment performance measure of Segment Adjusted EBITDA. Segment profit is similar to the GAAP measure of gross profit, except that segment profit excludes charges for depreciation, amortization and accretion. The most directly comparable measure to segment profit is gross profit.

The following table presents a reconciliation of segment profit to gross profit:

In addition, for the Fuel Distribution segment, the following section includes information on the components of segment profit by sales type, which components are included in order to provide additional disaggregated information to facilitate the analysis of segment profit and Segment Adjusted EBITDA. These components of segment profit are calculated consistent with the calculation of segment profit; therefore, these components also exclude charges for depreciation, amortization and accretion.

Fuel Distribution

(1) Excludes the impact of inventory valuation adjustments consistent with the definition of Adjusted EBITDA.

(2) Includes operating expenses, general and administrative and lease expense.

Volumes. For the three months ended March 31, 2026 compared to the same period last year, volumes increased primarily due to the Parkland Acquisition.

Segment Adjusted EBITDA. For the three months ended March 31, 2026 compared to the same period last year, Segment Adjusted EBITDA related to our Fuel Distribution segment increased due to the net impact of the following:

• an increase of $590 million in segment profit (excluding unrealized gains and losses on commodity risk management activities and inventory valuation adjustments) primarily due to the Parkland Acquisition and other acquisitions, as well as a favorable impact from a one-time gain on sale of inventory in the current period; and
• an increase of $8 million in Adjusted EBITDA related to unconsolidated affiliates from the Parkland Acquisition; partially offset by
• an increase of $299 million in expenses primarily due to the Parkland Acquisition.

Pipeline Systems

(1) Includes operating expenses, general and administrative and lease expense.

Volumes. For the three months ended March 31, 2026 compared to the same period last year, the increase in throughput volumes reflected the impact of refinery turnarounds in the prior period and overall increased market demand in 2026.

Segment Adjusted EBITDA. For the three months ended March 31, 2026 compared to the same period last year, Segment Adjusted EBITDA related to our Pipeline Systems segment increased due to the net impact of the following:

• a $10 million increase in segment profit primarily due to refinery turnarounds and contract expirations in the prior period, improved butane blending, and overall increased market demand; and
• a $6 million increase in Adjusted EBITDA related to ET-S Permian; partially offset by
• an $8 million increase in expenses primarily due to higher utility costs, maintenance costs and corporate allocations.

Terminals

(1) Includes operating expenses, general and administrative and lease expense.

Volumes. For the three months ended March 31, 2026 compared to the same period last year, volumes increased due to recently acquired assets.

Segment Adjusted EBITDA. For the three months ended March 31, 2026 compared to the same period last year, Segment Adjusted EBITDA related to our Terminals segment increased due to the net impact of the following:

• a $66 million increase in segment profit (excluding inventory valuation adjustments) primarily due to the acquisitions of Parkland and TanQuid; partially offset by
• a $25 million increase in expenses primarily due to the acquisitions of Parkland and TanQuid.

Refinery

(1) Refinery segment profit includes $61 million of production costs, supply and logistics, and terminal operating costs for the three months ended March 31, 2026.

(2) Includes operating expenses, general and administrative and lease expense.

Volumes. For the three months ended March 31, 2026 compared to the same period last year, volumes increased due to recently acquired assets.

Segment Adjusted EBITDA. For the three months ended March 31, 2026 compared to the same period last year, Segment Adjusted EBITDA related to our Refinery segment increased due to the Parkland Acquisition.

Liquidity and Capital Resources

Liquidity

Our principal liquidity requirements are to finance current operations, to fund capital expenditures, including acquisitions from time to time, to service our debt and to make distributions. We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our Credit Facility and the issuance of additional long-term debt or partnership units as appropriate given market conditions. We expect that these sources of funds will be adequate to provide for our short-term and long-term liquidity needs.

Our ability to meet our debt service obligations and other capital requirements, including capital expenditures and acquisitions, will depend on our future operating performance which, in turn, will be subject to general economic, financial, business, competitive, legislative, regulatory and other conditions, many of which are beyond our control. As a normal part of our business, depending on market conditions, we will from time to time consider opportunities to repay, redeem, repurchase or refinance our indebtedness. Changes in our operating plans, lower than anticipated sales, increased expenses, acquisitions or other events may cause us to seek additional debt or equity financing in future periods. There can be no guarantee that financing will be available on acceptable terms or at all. Debt financing, if available, could impose additional cash payment obligations and additional covenants and operating restrictions. In addition, any of the risks described or referenced under the heading “Part II - Item 1A. Risk Factors” herein, including the risk factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2025 may also significantly impact our liquidity.

As of March 31, 2026, we had $718 million of cash and cash equivalents on hand and borrowing capacity of $2.22 billion on our Credit Facility. The Partnership was in compliance with all financial covenants at March 31, 2026. Based on our current estimates, we expect to utilize capacity under the Credit Facility, along with cash from operations, to fund our announced growth capital expenditures and working capital needs for 2026; however, we may issue debt or equity securities as we deem prudent to provide liquidity for new capital projects or other partnership purposes.

Cash Flows

Our cash flows may change in the future due to a number of factors, some of which we cannot control. These factors include regulatory changes, the price of products and services, the demand for such products and services, margin requirements resulting from significant changes in commodity prices, operational risks, the successful integration of our acquisitions and other factors.

Operating Activities

Changes in cash flows from operating activities between periods primarily result from changes in earnings, excluding the impacts of non-cash items and changes in operating assets and liabilities (net of effects of acquisitions and divestitures). Non-cash items include recurring non-cash expenses, such as depreciation, amortization and accretion expense and non-cash unit-based

compensation expense. Cash flows from operating activities also differ from earnings as a result of non-cash charges that may not be recurring, such as impairment charges. Our daily working capital requirements fluctuate within each month, primarily in response to the timing of payments for motor fuels, motor fuels tax and rent.

Three months ended March 31, 2026 compared to three months ended March 31, 2025. Net cash provided by operating activities during 2026 was $454 million compared to $156 million for 2025, and net income was $644 million for 2026 and $207 million for 2025. The difference between net income and net cash provided by operating activities for the three months ended March 31, 2026 primarily consisted of net changes in operating assets and liabilities of $53 million and non-cash items totaling $178 million.

The non-cash activity in 2026 and 2025 consisted primarily of depreciation, amortization and accretion of $286 million and $156 million, respectively, non-cash unit-based compensation expense of $6 million and $4 million, respectively, favorable inventory valuation adjustments of $444 million and $61 million, respectively, loss on extinguishment of debt of $1 million and $2 million, respectively, gain on disposal of assets and impairment charges of $1 million and loss on disposal of assets and impairment charges of $3 million, respectively, amortization of deferred financing fees of $9 million and $3 million, respectively, and deferred income tax expense of $17 million and deferred income tax benefit of $7 million, respectively. Net income also included equity in earnings of unconsolidated affiliates of $42 million and $32 million in 2026 and 2025, respectively.

Cash provided by operating activities included cash distributions received from unconsolidated affiliates that were deemed to be paid from cumulative earnings, which distributions were $41 million in 2026 and $85 million in 2025.

Investing Activities

Cash flows from investing activities primarily consist of capital expenditures, cash contributions to unconsolidated affiliates, cash amounts paid for acquisitions and cash proceeds from the sale or disposal of assets. Changes in capital expenditures between periods primarily result from increases or decreases in our growth capital expenditures to fund our construction and expansion projects.

Three months ended March 31, 2026 compared to three months ended March 31, 2025. Net cash used in investing activities during 2026 was $430 million compared to $101 million in 2025. Capital expenditures for 2026 were $199 million compared to $101 million for 2025. In 2026, we paid $194 million for the acquisition of TanQuid and $50 million in cash for other acquisitions. In 2025, we paid $12 million in cash for other acquisitions. Proceeds from disposal of property, plant and equipment were $3 million for both periods.

In 2026 and in 2025, we paid $10 million and $24 million in cash contributions to unconsolidated affiliates, respectively. Distributions from unconsolidated affiliates in excess of cumulative earnings were $20 million and $33 million for 2026 and 2025, respectively.

Financing Activities

Changes in cash flows from financing activities between periods primarily result from changes in the levels of borrowings and equity issuances, which are primarily used to fund our acquisitions and growth capital expenditures. Distributions increase between the periods based on increases in the number of common units outstanding or increases in the distribution rate.

Three months ended March 31, 2026 compared to three months ended March 31, 2025. Net cash used in financing activities during 2026 was $197 million compared to net cash provided in financing activities of $23 million in 2025.

During the three months ended March 31, 2026, we:

• borrowed $1.20 billion and repaid $1.21 billion in senior notes;
• borrowed $1.18 billion and repaid $1.06 billion under the Credit Facility;
• paid $15 million in loan origination costs;
• paid $59 million in distributions to Series A Preferred unitholders;
• paid $48 million in distributions to Class D unitholders; and
• paid $189 million in distributions to our common unitholders, including incentive distributions.

During the three months ended March 31, 2025, we:

• borrowed $1.00 billion and repaid $603 million in senior notes;
• borrowed $1.09 billion and repaid $1.30 billion under the Credit Facility;
• paid $12 million in loan origination costs; and
• paid $159 million in distributions to our common unitholders, including incentive distributions.

We intend to pay cash distributions to the holders of our common units and Class C Units on a quarterly basis, to the extent we have sufficient cash from our operations after establishment of cash reserves and payment of fees and expenses, including payments to our General Partner and its affiliates. Class C unitholders receive distributions at a fixed rate equal to $0.8682 per quarter for each Class C Unit outstanding. There is no guarantee that we will pay a distribution on our units. On April 20, 2026, we declared a quarterly distribution of $0.9899 per common unit based on the results for the three months ended March 31, 2026, excluding distributions to Class C unitholders. The distribution will be approximately $136 million in the aggregate for common units, approximately $51 million with respect to Class D Units and approximately $71 million with respect to IDRs, and will be paid on May 20, 2026 to unitholders of record on May 8, 2026.

Capital Expenditures

For the three months ended March 31, 2026, total capital expenditures on an accrual basis were $199 million, which included $106 million for growth capital and $93 million for maintenance capital. This includes the Partnership's proportionate share of capital expenditures related to its investments in ET-S Permian and J.C. Nolan of $13 million for growth capital.

We currently expect to spend between $400 million and $450 million in maintenance capital expenditures and at least $600 million in growth capital for the full year 2026. These amounts include the Partnership's proportionate share for joint ventures.

Description of Indebtedness

As of the dates set forth below, our outstanding consolidated indebtedness was as follows:

(1) These senior notes were redeemed in March 2026. See additional information under “Recent Transactions.”

(2) As of March 31, 2026, $490 million aggregate principal amount of senior notes due before March 31, 2027 were classified as long-term as management has the intent and ability to refinance the borrowings on a long-term basis.

Recent Transactions

In March 2026, the Partnership issued $600 million aggregate principal amount of 5.375% senior notes due 2031 and $600 million aggregate principal amount of 5.625% senior notes due 2034. These notes will mature on July 15, 2031 and July 15, 2034, respectively, and interest is payable semi-annually on January 15 and July 15 of each year, commencing on July 15, 2026. The Partnership used a portion of the net proceeds from this private offering to redeem in full its $500 million aggregate principal amount of 6.000% senior notes due 2026 and its $600 million aggregate principal amount of 6.000% senior notes due 2027.

In March 2026, the Partnership redeemed Parkland's remaining senior notes.

Credit Facility

As of March 31, 2026, we had $125 million outstanding borrowings on the Credit Facility, which matures on June 17, 2030, and $151 million standby letters of credit were outstanding. The unused availability on the Credit Facility as of March 31, 2026 was $2.22 billion. The weighted average interest rate on the total amount outstanding as of March 31, 2026 was 5.52%. The Partnership was in compliance with all financial covenants as of March 31, 2026.

Upon the closing of the NuStar Acquisition, the commitments under NuStar’s receivables financing agreement were reduced to zero during a suspension period, for which the period end has not been determined. As of March 31, 2026, this facility had no outstanding borrowings.

Guarantor Summarized Financial Information

The senior notes issued by NuStar Logistics are fully and unconditionally guaranteed by Sunoco LP, Sunoco Finance Corp. and certain of its subsidiaries; the senior notes issued by Sunoco LP and the senior notes co-issued by Sunoco LP and Sunoco Finance Corp. are fully and unconditionally guaranteed by NuStar, NuStar Logistics and certain other subsidiaries. Each guarantee of the senior notes (i) ranks equally in right of payment with all other existing and future unsecured senior indebtedness of that guarantor, (ii) is structurally subordinated to all existing and any future indebtedness and obligations of any subsidiaries of that guarantor that do not guarantee the notes and (iii) ranks senior to its guarantee of our subordinated indebtedness. See Note 9 of the Notes to Financial Statements in Item 1. “Financial Statements” for a discussion of certain of our debt obligations.

The following tables present summarized combined balance sheet and income statement information for Sunoco LP, Sunoco Finance Corp. and NuStar Logistics (the “Issuers”), as well as the subsidiaries that guarantee the senior notes issued by those three entities (collectively with the Issuers, the “Guarantor Issuer Group”). Intercompany items among the Guarantor Issuer Group have been eliminated in the summarized combined financial information below, as well as intercompany balances and activity for the Guarantor Issuer Group with non-guarantor subsidiaries, including the Guarantor Issuer Group’s investment balances in non-guarantor subsidiaries.

(a)Excludes $330 million and $418 million of net intercompany payables owed to the non-guarantor subsidiaries from the Guarantor Issuer Group as of March 31, 2026 and December 31, 2025, respectively.

Long-term assets for the non-guarantor subsidiaries totaled $8.66 billion and $6.07 billion as of March 31, 2026 and December 31, 2025, respectively.

Revenues and net income for the non-guarantor subsidiaries totaled $5.27 billion and $85 million, respectively, for the three months ended March 31, 2026.

Critical Accounting Estimates

The Partnership's critical accounting estimates are described in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 19, 2026. No significant changes have occurred subsequent to the Form 10-K filing.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

We are subject to market risk from exposure to changes in interest rates based on our financing, investing and cash management activities. As of March 31, 2026, we had $179 million of variable rate debt outstanding. A hypothetical change of 100 basis points would result in a maximum potential change to interest expense of approximately $2 million annually.

Our primary exposure relates to:

• interest rate risk on short-term borrowings; and
• the impact of interest rate movements on our ability to obtain adequate financing to fund future acquisitions.

While we cannot predict or manage our ability to refinance existing debt or the impact interest rate movements will have on our existing debt, management evaluates our financial position on an ongoing basis. From time to time, we may enter into interest rate swaps to reduce the impact of changes in interest rates on our floating rate debt.

Commodity Price Risk

Our subsidiaries hold working inventories of refined petroleum products, renewable fuels, gasoline blendstocks and transmix in storage. As of March 31, 2026, we held approximately $1.89 billion of such inventory. While in storage, volatility in the market price of stored motor fuel could adversely impact the price at which we can later sell the motor fuel. However, we may use futures, forwards and other derivative instruments (collectively, “positions”) to hedge a variety of price risks relating to deviations in that inventory from a target base operating level established by management. Derivative instruments utilized consist primarily of exchange-traded futures contracts traded on the New York Mercantile Exchange, Chicago Mercantile Exchange and Intercontinental Exchange, as well as over-the-counter transactions (including swap agreements) entered into with established financial institutions and other credit-approved energy companies. While these derivative instruments represent economic hedges, they are not designated as hedges for accounting purposes. We may also engage in controlled trading in accordance with specific parameters set forth in a written risk management policy.

On a consolidated basis, the Partnership had derivative positions on 2.8 million barrels with an aggregate unrealized loss of $76 million at March 31, 2026, for which an assumed hypothetical 10% change in the underlying price of the commodity would result in an impact of approximately $24 million to pre-tax income, excluding any offsetting impact to the inventory that is economically hedged by these open positions.

Foreign Currency Translation Risk

We generate revenues, incur expenses, and maintain investments and subsidiaries in currencies other than the U.S. dollar. As a result, our reported earnings, cash flows, and AOCI are exposed to fluctuations in foreign currency exchange rates. Changes in exchange rates can affect the U.S. dollar value of our foreign‑currency‑denominated assets and liabilities, as well as the translation of the operating results and financial position of our international subsidiaries. We may utilize derivative instruments, including foreign currency forward contracts and other hedging strategies, to mitigate the effects of foreign currency‑denominated cash flow and earnings exposures. As of March 31, 2026, the Partnership did not have any outstanding foreign currency derivatives.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by paragraph (b) of Rule 13a-15 under the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, has concluded, as of the end of the period covered by this report, that our disclosure controls and procedures were effective at the reasonable assurance level for which they were designed in that the information required to be disclosed by the Partnership in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rule 13(a)-15(f) or Rule 15d-15(f) of the Exchange Act) during the three months ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
