Organization and Principles of Consolidation Organization and Principles of Consolidation
As used in this document, the terms “Company,” “SunocoCorp,” “we,” “us” or “our” should be understood to refer to SunocoCorp LLC, including its consolidated subsidiary, Sunoco LP.
The terms “Partnership” or “Sunoco” should be understood to refer to Sunoco LP and its consolidated subsidiaries.
SunocoCorp is a Texas publicly traded limited liability company that owns a direct limited partnership interest in Sunoco in the form of Sunoco Class D Units, representing limited partner interests in Sunoco (“Class D Units”), all of which are held by SunocoCorp. SunocoCorp’s only cash-generating asset is its investment in all of Sunoco's Class D Units. SunocoCorp is managed by SunocoCorp Manager, which is controlled by Energy Transfer.
Sunoco is a Texas master limited partnership. Sunoco is managed by Sunoco GP, which is owned by Energy Transfer. SunocoCorp currently holds the rights to appoint and remove the directors of the Sunoco GP Board. As of September 30, 2026, Energy Transfer owned 100% of the membership interest in Sunoco GP, 28,463,967 Sunoco Common Units and all of Sunoco’s IDRs.
Sunoco is primarily engaged in energy infrastructure and fuel distribution across 33 countries and territories in North America, the Greater Caribbean and Europe. Our midstream operations include an extensive network of approximately 14,000 miles of pipeline and over 170 terminals. Our fuel distribution operations have the capacity to distribute over 17 billion gallons annually (including Sunoco's most recent acquisition) to approximately 11,000 Sunoco and partner-branded retail locations, as well as independent dealers and commercial customers.
The consolidated financial statements of SunocoCorp presented herein have been prepared in accordance with GAAP and pursuant to the rules and regulations of the SEC. We consolidate Sunoco, as discussed below in “Change in Reporting Entity.” All significant intercompany transactions and accounts are eliminated in consolidation.
The operations of certain pipelines and terminals in which Sunoco owns an undivided interest are proportionately consolidated in the accompanying consolidated financial statements.
Change in Reporting Entity
SunocoCorp was previously named NuStar GP Holdings, LLC and was a consolidated subsidiary of Sunoco. SunocoCorp’s name was changed in 2025 in anticipation of the restructuring changes that occurred in connection with the Parkland Acquisition. Upon the consummation of the Parkland Acquisition, SunocoCorp became the primary beneficiary of Sunoco based on (i) SunocoCorp’s rights to appoint and remove the directors of the Sunoco GP Board and (ii) SunocoCorp’s economic interest in Sunoco held via 100% of the Sunoco Class D Units; accordingly, management concluded that SunocoCorp should consolidate Sunoco. Given SunocoCorp’s consolidation of its previous parent (Sunoco) upon the consummation of the Parkland Acquisition, management of the Company concluded that the restructuring constituted a change in reporting entity under Accounting Standards Codification Topic 250 (“ASC 250”), because the consolidated financial statements of the Company are, in effect, the statements of a different reporting entity. Accordingly, the Company’s consolidated financial statements prior to the Parkland Acquisition have been retrospectively restated to reflect the consolidation of Sunoco for all periods, and Sunoco’s equity prior to the Parkland Acquisition is reflected as “predecessor equity” in the Company’s consolidated financial statements for those periods.

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 September 30, 2026, there have been no changes in the Company'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 $82 million and $43 million for the three months ended September 30, 2026 and 2025, respectively, and $351 million and $107 million for the nine months ended September 30, 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 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.

On April 1, 2026, the Partnership completed the acquisition of Delta for approximately $81 million, excluding cash acquired and net working capital. The purchase price was allocated $36 million to property, plant and equipment, net, $15 million to intangible assets, and $24 million to goodwill. Delta owns and operates terminals and fuel distribution assets across five Caribbean markets. The transaction was funded using cash on hand and amounts available under the Partnership's Credit Facility.
Offen Acquisition
On October 27, 2026, the Partnership completed the previously announced acquisition of Offen Petroleum, whereby Sunoco Retail, a wholly owned corporate subsidiary of the Partnership, acquired all the equity interests of Offen Parent, LLC, the parent company of Offen Petroleum Holdings, LLC, in an all-cash transaction for approximately $600 million, plus working capital adjustments. Offen Petroleum operates a U.S.-based fuel distribution network delivering approximately 2.5 billion gallons annually, serving approximately 7,000 customers and over 800 retail stations across the Midwest, Mountain West, and Southwest regions of the U.S.
The acquisition will be 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, is in the process of determining 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.
Management expects that the purchase price will primarily be allocated to property, plant and equipment, intangible assets, and goodwill; however, 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 between line items on the consolidated balance sheet, potentially impacting deferred tax balances and/or goodwill.

Fuel inventories included balances stated at the lower of cost or market using the LIFO method, except for certain fuel inventories in the Caribbean, as discussed below. As of September 30, 2026 and December 31, 2025, the Partnership’s fuel inventory balance included lower of cost or market reserves of nil and $472 million, respectively. At September 30, 2026, the replacement cost of our fuel inventories accounted for using the LIFO method exceeded the carrying value by approximately $395 million.
For the three months ended September 30, 2026 and 2025, the Partnership's cost of sales included favorable inventory valuation adjustments of $19 million and $10 million, respectively, which increased net income. For the nine months ended September 30, 2026 and 2025, the Partnership’s cost of sales included favorable inventory valuation adjustments of $445 million and $31 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) for the nine months ended September 30, 2026, with no impact to the three months ended September 30, 2026. 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 $179 million and $88 million as of September 30, 2026 and December 31, 2025, respectively.

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.

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 September 30, 2026, the Credit Facility had $111 million outstanding borrowings, substantially all of which were CAD-denominated, and $84 million in standby letters of credit. The unused availability on the Credit Facility as of September 30, 2026 was $2.30 billion. The weighted average interest rate on the total amount outstanding as of September 30, 2026 was 4.35%. The Partnership was in compliance with all financial covenants as of September 30, 2026. The Partnership's net leverage ratio was 3.5 to 1.00 at September 30, 2026.
Receivables Financing Agreement

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, 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. The Comprehensive Environmental Response, Compensation, and Liability Act, as amended, imposes strict, joint and several liability on current and former owners and operators of contaminated facilities and on parties that transported or arranged for the transport or disposal of hazardous substances at a facility. 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 and at various waste disposal 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.

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 fuel to customers that include independently operated dealer and distributor stations, commission agent operators and commercial businesses. In addition, we supply our directly operated convenience retail facilities. Our Fuel Distribution segment also includes income from the Partnership’s properties that are leased, in addition to 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 102 refined product terminals (18 in Europe, six in Hawaii, nine in Canada, 20 in the Greater Caribbean and 49 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 assets, 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 and nine months ended September 30, 2026 and 2025:

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
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 4.5 million barrels with an aggregate unrealized gain of $23 million at September 30, 2026. As of September 30, 2026, the Partnership's interest rate swap derivative positions had a fair value of $8 million and were classified within Level 2 of the fair value hierarchy.
The following table summarizes the location and amounts recognized in our consolidated statements of operations with respect to our derivative financial instruments:

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 September 30, 2026, there have been no changes in the Company'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
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 $82 million and $43 million for the three months ended September 30, 2026 and 2025, respectively, and $351 million and $107 million for the nine months ended September 30, 2026 and 2025, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in our consolidated statements of operations.

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) for the nine months ended September 30, 2026, with no impact to the three months ended September 30, 2026. 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.

Delta Acquisition
On April 1, 2026, the Partnership completed the acquisition of Delta for approximately $81 million, excluding cash acquired and net working capital. The purchase price was allocated $36 million to property, plant and equipment, net, $15 million to intangible assets, and $24 million to goodwill. Delta owns and operates terminals and fuel distribution assets across five Caribbean markets. The transaction was funded using cash on hand and amounts available under the Partnership's Credit Facility.
Offen Acquisition
On October 27, 2026, the Partnership completed the previously announced acquisition of Offen Petroleum, whereby Sunoco Retail, a wholly owned corporate subsidiary of the Partnership, acquired all the equity interests of Offen Parent, LLC, the parent company of Offen Petroleum Holdings, LLC, in an all-cash transaction for approximately $600 million, plus working capital adjustments. Offen Petroleum operates a U.S.-based fuel distribution network delivering approximately 2.5 billion gallons annually, serving approximately 7,000 customers and over 800 retail stations across the Midwest, Mountain West, and Southwest regions of the U.S.
The acquisition will be 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, is in the process of determining 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.
Management expects that the purchase price will primarily be allocated to property, plant and equipment, intangible assets, and goodwill; however, 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 between line items on the consolidated balance sheet, potentially impacting deferred tax balances and/or goodwill.
