Organization and Principles of Consolidation 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.

Significant Accounting Policies [Text Block] 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.

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.

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.

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.

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.

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.
Fair Value of Debt
The aggregate estimated fair value and carrying amount of our consolidated debt obligations as of March 31, 2026 were $13.99 billion and $13.93 billion, respectively. As of December 31, 2025, the aggregate fair value and carrying amount of our consolidated debt obligations were $13.52 billion and $13.39 billion, respectively. The fair value of our consolidated debt obligations is a Level 2 valuation based on the respective debt obligations' observable inputs for similar liabilities.

Commitments and Contingencies 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.

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”).

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.

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.

Segment Reporting [Abstract]  
Segment Reporting [Text Block] 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:

Derivative Instruments and Hedging Activities Disclosure 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.

Motor Fuel and Sales Taxes
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.
