Organization and Principles of Consolidation Organization and Principles of Consolidation
As used in this document, the terms “Partnership,” “SUN,” “we,” “us” and “our” should be understood to refer to Sunoco LP and our consolidated subsidiaries, unless the context clearly indicates otherwise.
We are a Delaware master limited partnership. We are managed by our general partner, Sunoco GP LLC (“General Partner”), which is owned by Energy Transfer LP (“Energy Transfer”). As of December 31, 2024, Energy Transfer and its subsidiaries owned 100% of the membership interest in our General Partner, 28,463,967 of our common units and all of our incentive distribution rights (“IDRs”)
We are primarily engaged in energy infrastructure and distribution of motor fuels in over 40 U.S. states, Puerto Rico, Europe and Mexico. Our midstream operations include an extensive network of over 14,000 miles of pipeline and over 100 terminals. Our fuel distribution operations serve approximately 7,400 Sunoco and partner branded locations and additional independent dealers and commercial customers.
The consolidated financial statements of Sunoco LP presented herein for the years ended December 31, 2024, 2023 and 2022, have been prepared in accordance with GAAP and pursuant to the rules and regulations of the SEC. We consolidate all wholly owned subsidiaries. All significant intercompany transactions and accounts are 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.
Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on net income, total equity or cash flows.

Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Use of Estimates
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurements
We use fair value measurements to measure, among other items, purchased assets, investments, leases and derivative contracts. We also use them to assess impairment of properties, equipment, intangible assets and goodwill. An asset’s fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters, or is derived from such prices or parameters. Where observable prices or inputs are not available, unobservable prices or inputs are used to estimate the current fair value, often using an internal valuation model. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the item being valued.
ASC 820 “Fair Value Measurements and Disclosures” prioritizes the inputs used in measuring fair value into the following hierarchy:
Level 1    Quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2    Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable;
Level 3    Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.
Cash, accounts receivable, certain other current assets, marketable securities, accounts payable, accrued expenses and certain other current liabilities are reflected in the consolidated balance sheets at carrying amounts, which approximate the fair value due to their short term nature.
Segment Reporting
We operate our business in three reportable segments: Fuel Distribution, Pipeline Systems and Terminals. 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 Hawaii and New Jersey. Our Pipeline Systems segment includes an integrated pipeline and terminal network comprised of refined product, crude oil and ammonia pipelines and terminals, including our investments in the J.C. Nolan and ET-S Permian joint ventures. Our Terminals segment is composed of four transmix processing facilities and 56 refined product terminals (two in Europe, six in Hawaii and 48 in the continental United States).
Acquisition Accounting
Acquisitions of assets or entities that include inputs and processes and have the ability to create outputs are accounted for as business combinations. A purchase price allocation is recorded for tangible and intangible assets acquired and liabilities assumed based on their fair value. The excess of fair value of consideration conveyed over fair value of net assets acquired is recorded as goodwill. The consolidated statements of operations and comprehensive income for the periods presented include the results of operations for each acquisition from their respective dates of acquisition.
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.
Sunoco, LLC and Sunoco Retail LLC, our indirect wholly owned subsidiary that is subject to state and federal income tax (“Sunoco Retail”), have treasury services agreements with Energy Transfer (R&M), LLC, an indirect wholly owned subsidiary of Energy Transfer, for certain cash management activities. The net balance of Sunoco LLC and Sunoco Retail activity is reflected in either “Advances to affiliates” or “Advances from affiliates” on the consolidated balance sheets.
Accounts Receivable
The majority of trade receivables are from wholesale fuel customers or from credit card companies related to retail credit card transactions. Wholesale customer credit is extended based on an evaluation of the customer’s financial condition. We maintain allowances for expected credit losses based on the best estimate of the amount of expected credit losses in existing accounts receivable. Credit losses are recorded against the allowance when accounts are deemed uncollectible.
Receivables from affiliates arise from fuel sales and other miscellaneous transactions with non-consolidated affiliates. These receivables are recorded at face value, without interest or discount.
7-Eleven, Inc. is the only third-party dealer or distributor which is individually over 10% of our Fuel Distribution segment or individually over 10%, in terms of revenue, of our aggregate business.
Inventories
Fuel inventories are stated at the lower of cost or market using the last-in, first-out method (“LIFO”). Under this methodology, the cost of fuel sold consists of actual acquisition costs, which includes transportation and storage costs. Such costs are adjusted to reflect increases or decreases in inventory quantities which are valued based on changes in LIFO inventory layers.
Merchandise inventories are stated at the lower of average cost, as determined by the retail inventory method, or market. We record an allowance for shortages and obsolescence relating to merchandise inventory based on historical trends and any known changes. Shipping and handling costs are included in the cost of merchandise inventories.
Advertising Costs
Advertising costs are expensed as incurred. Advertising costs were $30 million, $26 million and $25 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Property and Equipment
Property and equipment are recorded at cost. Depreciation is computed on a straight-line basis over the useful lives of assets. Assets under finance leases are depreciated over the life of the corresponding lease.
Amortization of leasehold improvements is based upon the shorter of the remaining terms of the leases including renewal periods that are reasonably assured, or the estimated useful lives, which approximate twenty years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Maintenance and repairs are charged to operations as incurred. Gains or losses on the disposition of property and equipment are recorded in the period incurred.
Long-Lived Assets and Assets Held for Sale
Long-lived assets are tested for possible impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. If such indicators exist, the estimated undiscounted future cash flows related to the asset are compared to the carrying value of the asset. If the carrying value is greater than the estimated undiscounted future cash flows, an
impairment charge is recorded in the consolidated statements of operations and comprehensive income for amounts necessary to reduce the corresponding carrying value of the asset to fair value. The impairment loss calculations require management to apply judgment in estimating future cash flows.
Properties that have been closed and other excess real property are recorded as assets held for sale, and are written down to the lower of cost or estimated net realizable value at the time we close such stores or determine that these properties are in excess and intend to offer them for sale. We estimate the net realizable value based on our experience in utilizing or disposing of similar assets and on estimates provided by our own and third-party real estate experts. Although we have not experienced significant changes in our estimate of net realizable value, changes in real estate markets could significantly impact the net values realized from the sale of assets.
Goodwill and Indefinite-Lived Intangible Assets
Goodwill represents the excess of consideration paid over fair value of net assets acquired. Goodwill and intangible assets acquired in a purchase business combination are recorded at fair value as of the date acquired. Acquired intangible assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment at least annually, or more frequently if events and circumstances indicate that the asset might be impaired. The annual impairment test of goodwill and indefinite lived intangible assets is performed as of the first day of the fourth quarter of each fiscal year.
The Partnership uses qualitative factors to determine whether it is more likely than not (likelihood of more than 50%) that the fair value of a reporting unit exceeds its carrying amount, including goodwill. Some of the qualitative factors considered in applying this test include consideration of macroeconomic conditions, industry and market conditions, cost factors affecting the business, overall financial performance of the business and performance of the unit price of the Partnership.
If qualitative factors are not deemed sufficient to conclude that the fair value of the reporting unit more likely than not exceeds its carrying value, then a quantitative approach is applied in making an evaluation. The quantitative evaluation utilizes multiple valuation methodologies, including a market approach (market price multiples of comparable companies), an income approach (discounted cash flow analysis), or a weighted combination of these methods. The computations require management to make significant estimates and assumptions, including, among other things, selection of comparable publicly traded companies, the discount rate applied to future earnings reflecting a weighted average cost of capital and earnings growth assumptions. The Partnership believes the estimates and assumptions used in our impairment assessments are reasonable and based on available market information, but variations in any of the assumptions could result in materially different calculations of fair value and determinations of whether or not an impairment is indicated. A discounted cash flow analysis requires management to make various assumptions about future sales, operating margins, capital expenditures, working capital and growth rates. Cash flow projections are derived from one-year budgeted amounts plus an estimate of later period cash flows, all of which are determined by management. Subsequent period cash flows are developed for each reporting unit using growth rates that management believes are reasonably likely to occur. Under the guideline company method, the Partnership determined the estimated fair value of each of our reporting units by applying valuation multiples of comparable publicly-traded companies to each reporting unit’s projected EBITDA and then averaging that estimate with similar historical calculations using a three-year average. In addition, the Partnership estimated a reasonable control premium representing the incremental value that accrues to the majority owner from the opportunity to dictate the strategic and operational actions of the business. If the evaluation results in the fair value of the reporting unit being lower than the carrying value, an impairment charge is recorded.
Indefinite-lived intangible assets are composed of certain tradenames and liquor licenses which are not amortized but are evaluated for impairment annually or more frequently if events or changes occur that suggest an impairment in carrying value, such as a significant adverse change in the business climate. Indefinite-lived intangible assets are evaluated for impairment by comparing each asset’s fair value to its book value. Management first determines qualitatively whether it is more likely than not that an indefinite‑lived asset is impaired. If management concludes that it is more likely than not that an indefinite-lived asset is impaired, then its fair value is determined by using the discounted cash flow model based on future revenues estimated to be derived in the use of the asset.
Other Intangible Assets
Other finite-lived intangible assets consist of supply agreements, customer relations, non-compete agreements and loan origination costs. Separable intangible assets that are not determined to have an indefinite life are amortized over their useful lives and assessed for impairment only if and when circumstances warrant. Determination of an intangible asset’s fair value and estimated useful life are based on an analysis of pertinent factors including: (1) the use of widely-accepted valuation approaches, such as the income approach or the cost approach, (2) the expected use of the asset by the Partnership, (3) the expected useful life of related assets, (4) any legal, regulatory or contractual provisions, including renewal or extension periods that would cause substantial costs or modifications to existing agreements and (5) the effects of obsolescence, demand, competition and other economic factors. Should any of the underlying assumptions indicate that the value of the intangible assets might be impaired, we may be required to reduce the carrying value and remaining useful life of the asset. If the underlying assumptions governing the
amortization of an intangible asset were later determined to have significantly changed, we may be required to adjust its amortization period to reflect a new estimate of its useful life. Any write-down of the value or unfavorable change in the useful life of an intangible asset would increase expense at that time.
Customer relations and supply agreements are amortized on a straight-line basis over the remaining terms of the agreements, which generally range from five to twenty years. Non-compete agreements are amortized over the terms of the respective agreements.
Investments in Unconsolidated Affiliates
We own interests in certain joint ventures with Energy Transfer that are accounted for by the equity method. In general, we use the equity method of accounting for an investment for which we exercise significant influence over, but do not control, the investee’s operating and financial policies. An impairment of an investment in an unconsolidated affiliate is recognized when circumstances indicate that a decline in the investment value is other-than-temporary.
Asset Retirement Obligations
The estimated future cost to remove an underground storage tank is recognized over the estimated useful life of the storage tank. We record a discounted liability for the future fair value of an asset retirement obligation along with a corresponding increase to the carrying value of the related long-lived asset at the time an underground storage tank is installed. We then depreciate the amount added to property and equipment and recognize accretion expense in connection with the discounted liability over the remaining life of the tank. We base our estimates of the anticipated future costs for tank removal on our prior experience with removals. We review assumptions for computing the estimated liability for tank removal on an annual basis. Any change in estimated cash flows are reflected as an adjustment to both the liability and the associated asset.
Long-lived assets related to asset retirement obligations aggregated $12 million and $13 million as of December 31, 2024 and 2023, respectively, and were reflected as property and equipment, net, on our consolidated balance sheets.
Environmental Liabilities
Environmental expenditures related to existing conditions, resulting from past or current operations and from which no current or future benefit is discernible, are expensed. Expenditures that extend the life of the related property or prevent future environmental contamination are capitalized. We determine and establish a liability on a site-by-site basis when future environmental expenditures are probable and can be reasonably estimated. A related receivable is recorded for estimable and probable reimbursements.
Revenue Recognition
Revenues from our Fuel Distribution segment are derived from the sale of fuel, non-fuel and lease income. Fuel sales consist primarily of the sale of motor fuel under supply agreements with third-party customers and affiliates. Fuel supply contracts with our customers generally provide that we distribute motor fuel at a price based on a formula which includes published rates, volume-based profit margin and other terms specific to the agreement. The customer is invoiced the agreed-upon price with most payment terms ranging less than 30 days. If the consideration promised in a contract includes a variable amount, the Partnership estimates the variable consideration amount and factors in such estimate to determine the transaction price under the expected value method. Revenue is recognized under the motor fuel contracts at the point in time the customer takes control of the fuel. At the time control is transferred to the customer the sale is considered final, because the agreements do not grant customers the right to return motor fuel. To determine when control transfers to the customer, the shipping terms of the contract are assessed as a primary indicator of the transfer of control. For free on board (“FOB”) shipping point terms, revenue is recognized at the time of shipment. The performance obligation with respect to the sale of goods is satisfied at the time of shipment since the customer gains control at this time under the terms. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. Once the goods are shipped, the Partnership is precluded from redirecting the shipment to another customer and revenue is recognized. Non-fuel revenue includes merchandise revenue that comprises the in-store merchandise and food service sales at company-operated retail stores and other revenue such as credit card processing, car washes, lottery and other services. Lease revenue is derived from leasing arrangements for which we are the lessor and recognized ratably over the term of the underlying lease.
Revenues from our Pipeline Systems segment are derived from interstate and intrastate pipeline transportation of refined products, crude oil and anhydrous ammonia and the applicable pipeline tariff on a per barrel basis for crude oil or refined products and on a per ton basis for ammonia.
Revenues from our Terminals segment include fees for tank storage agreements, under which a customer agrees to pay for a certain amount of storage in a tank over a period of time and throughput agreements, under which a customer pays a fee per barrel for volumes moving through our terminals. Our terminals also provide blending, additive injections, handling and filtering services for which we charge additional fees.
Lease Income
Lease income from leasing or subleasing of real estate is recognized on a straight-line basis over the term of the lease.
Cost of Sales
We include in cost of sales all costs incurred to acquire fuel and merchandise, including the costs of purchasing, storing and transporting inventory prior to delivery to our customers. Items are removed from inventory and are included in cost of sales based on the retail inventory method for merchandise and the LIFO method for motor fuel. Cost of sales does not include depreciation of property and equipment as amounts attributed to cost of sales would not be significant. Depreciation is classified within operating expenses in the consolidated statements of operations and comprehensive income.
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 $164 million, $274 million and $285 million for the years ended December 31, 2024, 2023 and 2022, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in our consolidated statements of operations and comprehensive income.
Deferred Branding Incentives
We receive payments for branding incentives related to fuel supply contracts. Unearned branding incentives are deferred and amortized on a straight-line basis over the term of the agreement as a credit to cost of sales.
Lease Accounting
At the inception of each lease arrangement, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify lease assets as operating or finance leases under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on our consolidated balance sheets.
Balances related to operating leases are included in operating lease right-of-use assets, net, operating lease current liabilities and non-current operating lease liabilities on our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in other non-current assets and long-term debt, net on our consolidated balance sheets. The right-of-use assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the obligation of the Partnership to make minimum lease payments arising from the lease for the duration of the lease term.
The Partnership leases a portion of its properties under non-cancelable operating leases, whose initial terms are typically five to fifteen years, with options permitting renewal for additional periods. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or greater. The exercise of lease renewal options is typically at the sole discretion of the Partnership and lease extensions are evaluated on a lease-by-lease basis. Leases containing early termination clauses typically require the agreement of both parties to the lease. At the inception of a lease, all renewal options reasonably certain to be exercised are considered when determining the lease term. The depreciable life of lease assets and leasehold improvements are limited by the expected lease term.
To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. Presently, because many of our leases do not provide an implicit rate, the Partnership applies its incremental borrowing rate based on the information available at the lease commencement date to determine the present value of minimum lease payments. The operating and finance lease right-of-use assets include any lease payments made and exclude lease incentives.
Minimum rent is expensed on a straight-line basis over the term of the lease, including renewal periods that are reasonably assured at the inception of the lease. The Partnership is typically responsible for payment of real estate taxes, maintenance expenses and insurance. The Partnership also leases certain vehicles, and such leases are typically less than five years.
For short-term leases (leases that have term of 12 months or less upon commencement), lease payments are recognized on a straight-line basis and no right-of-use assets are recorded.
Earnings Per Unit
In addition to limited partner units, we have IDRs as participating securities and compute net income per common unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Second Amended and Restated Agreement of Limited Partnership, as may be amended from time to time (the “Partnership Agreement”). Net income per unit applicable to limited partners is computed by
dividing limited partners’ interest in net income, after deducting any incentive distributions and distributions on unvested phantom unit awards, by the weighted average number of outstanding common units.
Defined Benefit Plans
We estimate pension and other postretirement benefit obligations and costs based on actuarial valuations. The annual measurement date for our pension and other postretirement benefit plans is December 31. The actuarial valuations require the use of certain assumptions including discount rates, expected long-term rates of return on plan assets and expected rates of compensation increase. Changes in these assumptions are primarily influenced by factors outside of our control.
Unit-Based Compensation
Under the Partnership's long-term incentive plans, various types of awards may be granted to employees, consultants and directors of our General Partner who provide services for us. Compensation expense related to outstanding awards is recognized over the vesting period based on the grant-date fair value. The grant-date fair value is determined based on the market price of our common units on the grant date. We amortize the grant-date fair value of these awards over their vesting period using the straight-line method. Expenses related to unit-based compensation are included in general and administrative expenses.
Foreign Currency Translation
The functional currencies of our foreign subsidiaries are the local currencies of the countries in which the subsidiaries are located. The assets and liabilities of our foreign subsidiaries with local functional currencies are translated to U.S. dollars at period-end exchange rates, and income and expense items are translated to U.S. dollars at weighted-average exchange rates in effect during the period. These translation adjustments are included in accumulated other comprehensive income ("AOCI") in the equity section of the consolidated balance sheets. Upon the sale or liquidation of our investment in a foreign subsidiary, translation adjustments that have historically accumulated in AOCI related to that subsidiary are released from AOCI and reported as part of the gain or loss on sale. Gains and losses on foreign currency transactions are included in other income (expense), net in the consolidated statements of operations.
Income Taxes
The Partnership is a publicly traded limited partnership and is not taxable for federal and most state income tax purposes. As a result, our earnings or losses, to the extent not included in a taxable subsidiary, for federal and most state purposes are included in the tax returns of the individual partners. Net earnings for financial statement purposes may differ significantly from taxable income reportable to Unitholders as a result of differences between the tax basis and financial basis of assets and liabilities, differences between the tax accounting and financial accounting treatment of certain items, and due to allocation requirements related to taxable income under our Partnership Agreement. We do not have access to information regarding each partner's individual tax basis in our limited partner interests.
As a publicly traded limited partnership, we are subject to a statutory requirement that our “qualifying income” (as defined by the Internal Revenue Code, related Treasury Regulations and IRS pronouncements) exceed 90% of our total gross income, determined on a calendar year basis. If our qualifying income were not to meet this statutory requirement, the Partnership would be taxed as a corporation for federal and state income tax purposes. For the years ended December 31, 2024, 2023 and 2022, our qualifying income met the statutory requirement.
The Partnership conducts certain activities through corporate subsidiaries which are subject to federal, state, local and foreign income taxes. The Partnership and its corporate subsidiaries account for income taxes under the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized.
The determination of the provision for income taxes requires significant judgment, use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our consolidated financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. When facts and circumstances change, we reassess these probabilities and record any changes through the provision for income taxes.
Recent Accounting Pronouncements
In November 2024, Financial Accounting Standards Board (“FASB”) 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.

NuStar Acquisition
On May 3, 2024, we completed the acquisition of 100% of the common units of NuStar Energy L.P. (“NuStar”). Under the terms of the agreement, NuStar common unitholders received 0.400 SUN common units for each NuStar common unit. In connection with the acquisition, we issued approximately 51.5 million common units, which had a fair value of approximately $2.85 billion, assumed debt totaling approximately $3.5 billion, including approximately $56 million of lease related financing obligations, and assumed preferred units with a fair value of approximately $800 million. NuStar has approximately 9,500 miles of pipeline and 63 terminal and storage facilities that store and distribute crude oil, refined products, renewable fuels, ammonia and specialty liquids. The acquisition is expected to diversify the Partnership’s business, increase scale and provide vertical integration, as well as improving the Partnership’s credit profile and enhancing growth.
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.
The following table summarizes the allocation of the purchase price among assets acquired and liabilities assumed:

(1)Goodwill primarily represents expected commercial and operational synergies. None of the goodwill recorded as a result of this transaction is deductible for tax purposes. Goodwill of $16 million relates to our Fuel Distribution segment.
(2)Intangible assets, net comprised $151 million of favorable contracts, with a remaining weighted average life of approximately 7 years, and $44 million of customer relationships with a remaining weighted average life of approximately 15 years.
(3)Subsequent to the closing of the NuStar acquisition, the Partnership redeemed all outstanding NuStar preferred units, totaling $784 million, redeemed NuStar's subordinated notes totaling $403 million and repaid and terminated the NuStar credit facility totaling $455 million.
Subsequent to the NuStar acquisition, the Partnership purchased a property previously leased by NuStar and cancelled the lease, resulting in an impairment of $50 million based on the value of comparable real property.

Expenses Related to the NuStar Acquisition
As a result of the acquisition, we recognized $103 million of merger-related expenses during the year ended December 31, 2024, which are included in general and administrative expenses in our consolidated statement of operations.
Zenith European Terminals Acquisition
On March 13, 2024, we completed the acquisition of liquid fuels terminals in Amsterdam, Netherlands and Bantry Bay, Ireland from Zenith Energy for €170 million ($185 million), including working capital. The acquisition is expected to supply optimization for the Partnership’s existing East Coast business and continues its focus on growing its portfolio of stable midstream income. 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. 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.

On August 30, 2024, we acquired a terminal in Portland, Maine for approximately $24 million, including working capital. The purchase price was primarily allocated to property and equipment.
West Texas Sale
On April 16, 2024, we completed the sale of 204 convenience stores located in West Texas, New Mexico and Oklahoma to 7-Eleven, Inc. for approximately $1.0 billion, including customary adjustments for fuel and merchandise inventory. As part of the sale, SUN also amended its existing take-or-pay fuel supply agreement with 7-Eleven, Inc. to incorporate additional fuel gross profit. As a result of the sale, the Partnership recorded a $586 million gain ($442 million, net of current tax expense of $179 million and deferred tax benefit of $35 million).
ET-S Permian
Effective July 1, 2024, SUN and Energy Transfer formed ET-S Permian, a joint venture combining their respective crude oil and produced water gathering assets in the Permian Basin. Pursuant to the contribution agreement by and among the Partnership, SUN Pipeline Holdings LLC, NuStar Permian Transportation and Storage LLC, NuStar Permian Crude Logistics LLC, NuStar Permian Holdings LLC, NuStar Logistics, L.P., ET-S Permian Holdings Company LP, ET-S Permian Pipeline Company LLC, ET-S Permian Marketing Company LLC, Energy Transfer LP, and Energy Transfer Crude Marketing, LLC dated July 14, 2024, in a cashless transaction, SUN contributed all of its Permian crude oil gathering assets and operations to ET-S Permian. Energy Transfer contributed its Permian crude oil and produced water gathering assets and operations to ET-S Permian. Energy Transfer’s long-haul crude pipeline network that provides transportation of crude oil out of the Permian Basin to Nederland, Houston, and Cushing is excluded from ET-S Permian.
ET-S Permian operates more than 5,000 miles of crude oil and water gathering pipelines with crude oil storage capacity in excess of 11 million barrels.
SUN holds a 32.5% interest, with Energy Transfer holding the remaining 67.5% interest in ET-S Permian. Energy Transfer serves as the operator of ET-S Permian.
Upon formation, the SUN Permian entities were deconsolidated; however, no gain or loss was recorded in net income due to the common control nature of the transaction. As of December 31, 2024, the carrying value of the Partnership’s investment in ET-S Permian was $1.21 billion.
As of December 31, 2024, ET-S Permian had current assets of $273 million, noncurrent assets of $3.61 billion, current liabilities of $106 million and noncurrent liabilities of $50 million. For the six months ended December 31, 2024, ET-S Permian recognized revenues of $8.70 billion, of which approximately $8.48 billion related to transactions with affiliates, operating income of $164 million and net income of $163 million.
2023 Acquisition
On May 1, 2023, we completed the acquisition of 16 refined product terminals located across the East Coast and Midwest from Zenith Energy for approximately $111 million, including working capital. The purchase price was primarily allocated to property and equipment.
2022 Acquisitions
On November 30, 2022, we completed the acquisition of Peerless for $67 million, net of cash acquired. Peerless is an established terminal operator that distributes fuel products to over 100 locations primarily within Puerto Rico. Management, with the assistance of an independent valuation firm, determined the fair value of assets and liabilities at the date of the acquisition. Goodwill acquired in connection with the acquisition is deductible for tax purposes.

Recent Transactions
NuStar Acquisition
During the second quarter of 2024, subsequent to the closing of the NuStar acquisition, the Partnership redeemed NuStar's subordinated notes totaling $403 million and repaid and terminated NuStar's credit facility totaling $455 million. 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 December 31, 2024, this facility had no outstanding borrowings.
NuStar Logistics Senior Notes. NuStar Logistics, L.P., a wholly owned subsidiary acquired in the NuStar acquisition (“NuStar Logistics”) is the issuer of $2.25 billion of senior notes, including 5.750% senior notes due 2025, 6.000% senior notes due 2026, 5.625% senior notes due 2027 and 6.375% senior notes due 2030 (collectively, the “NuStar Logistics Senior Notes”). Subsequent to the closing of the NuStar acquisition, the indentures related to the Partnership’s senior notes (“SUN Senior Notes”) and the indentures related to NuStar Logistics’ Senior Notes were amended to add certain subsidiaries as guarantors. Consequently, SUN and NuStar Logistics are each a guarantor of the other’s senior notes, along with other subsidiary guarantors of each.
The NuStar Logistics Senior Notes do not have sinking fund requirements. These notes rank equally with existing senior unsecured indebtedness and senior to existing subordinated indebtedness of NuStar Logistics and contain restrictions on NuStar Logistics’ ability to incur secured indebtedness unless the same security is also provided for the benefit of holders of the NuStar Logistics Senior Notes. In addition, the NuStar Logistics Senior Notes limit the ability of NuStar Logistics and its subsidiaries to, among other things, incur indebtedness secured by certain liens, engage in certain sale-leaseback transactions and engage in certain consolidations, mergers or asset sales. At the option of NuStar Logistics, the NuStar Logistics Senior Notes may be redeemed in whole or in part at any time at a redemption price, plus accrued and unpaid interest to the redemption date. If we undergo a change of control that is followed by a ratings decline that occurs within 60 days of the change of control, each holder of the applicable senior notes may require us to repurchase all or a portion of its notes at a price equal to 101% of the principal amount of the notes repurchased, plus any accrued and unpaid interest to the date of repurchase.
Gulf Opportunity Zone Revenue Bonds. NuStar Logistics’ obligations also 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 are expected to 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 our 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 December 31, 2024:

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 we undergo 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.
SUN Senior Notes
The terms of each tranche of SUN Senior Notes are governed by indentures among the Partnership and Sunoco Finance Corp. (together, the “Issuers”), and certain other subsidiaries of the Partnership and U.S. Bank National Association, as trustee. The SUN Senior Notes are senior obligations of the Issuers and are guaranteed by all of the Partnership’s existing subsidiaries and certain of its future subsidiaries. The SUN Senior Notes and guarantees are unsecured and rank equally with all of the Issuers’ and each Guarantor’s existing and future senior obligations. The SUN Senior Notes and guarantees are effectively subordinated to the
Issuers’ and each Guarantor’s secured obligations, including obligations under the Partnership’s Credit Facility (as defined below), to the extent of the value of the collateral securing such obligations, and structurally subordinated to all indebtedness and obligations, including trade payables, of the Partnership’s subsidiaries that do not guarantee the SUN Senior Notes.
On April 30, 2024, the Partnership issued $750 million of 7.000% senior notes due 2029 and $750 million of 7.250% senior notes due 2032 in a private offering. The Partnership used the net proceeds from the offering to: (i) repay certain outstanding indebtedness of NuStar in connection with the merger between the Partnership and NuStar, (ii) fund the redemption of NuStar's preferred units in connection with the merger and (iii) pay offering fees and expenses.
Energy Transfer guarantees collection to the Issuers with respect to the payment of the principal amount of the 5.875% senior notes due 2028. Energy Transfer is not subject to any of the covenants under the Indenture.
Credit Facility
On May 3, 2024, we entered into a Third Amended and Restated Credit Agreement among the Partnership, as borrower, the lenders from time to time party thereto and Bank of America, N.A., as administrative agent, collateral agent, swingline lender and a letter of credit issuer (the “Credit Facility”). The Credit Facility is a $1.50 billion revolving credit facility which matures on May 3, 2029 (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 our written request, subject to certain conditions, up to an additional $500 million.
Borrowings under the Credit Facility will bear interest, at the Borrower’s election, at a rate equal to Term SOFR (as defined therein) or a base rate (a rate based off of the higher of (a) the Federal Funds Rate (as defined therein) plus 0.500%, (b) Bank of America’s prime rate and (c) one-month Term SOFR (as defined therein) plus 1.00%), in each case plus an applicable margin ranging from 1.250% to 2.250%, in the case of a Term SOFR loan, or from 0.250% to 1.25%, in the case of a base rate loan (determined with reference to the Partnership’s Net Leverage Ratio as defined in the Credit Facility). Upon the first achievement by the Partnership of an investment grade credit rating, the applicable margin will decrease to a range of 1.125% to 1.750%, in the case of a Term SOFR loan, or from 0.125% to 0.750%, in the case of a base rate loan (determined with reference to the credit rating for the Partnership’s senior, unsecured, non-credit enhanced long-term debt and the Partnership’s corporate issuer rating). Interest is payable quarterly if the base rate applies, and at the end of the applicable interest period if Term SOFR applies. In addition, the unused portion of the Partnership’s Credit Facility will be subject to a commitment fee ranging from 0.250% to 0.350%, based on the Partnership’s Net Leverage Ratio. Upon the first achievement by the Partnership of an investment grade credit rating, the commitment fee will decrease to a range of 0.125% to 0.350%, based on the Partnership’s credit rating as described above.
The Credit Facility requires the Partnership to maintain a Net Leverage Ratio of not more than 5.50 to 1.00 before the first achievement by the Partnership of an investment grade credit rating, and from and after the first occurrence of an investment grade credit rating, a Net Leverage Ratio of not more than 5.00 to 1.00. The maximum Net Leverage Ratio is subject to upwards adjustment after the achievement by the Partnership of an investment grade credit rating to not more than 5.50 to 1.00 for a period not to exceed three fiscal quarters in the event the Partnership engages in certain specified acquisitions of not less than $50 million (as permitted under the Credit Facility). The Credit Facility also requires the Partnership to maintain an Interest Coverage Ratio (as defined in the Credit Facility) of not less than 2.25 to 1.00.
Indebtedness under the Credit Facility is guaranteed by material domestic subsidiaries of the Partnership and other subsidiaries for which the Partnership elects to provide guarantees.
As of December 31, 2024, the balance on the Credit Facility was $203 million, and $43 million in standby letters of credit were outstanding. The unused availability on the Credit Facility at December 31, 2024 was $1.25 billion. The weighted average interest rate on the total amount outstanding at December 31, 2024 was 6.57%. The Partnership was in compliance with all financial covenants at December 31, 2024. The Partnership’s net leverage ratio was 4.08 to 1.00 at December 31, 2024.
Lease-Related Financing Obligations
Southside Oil, LLC, a subsidiary of the Partnership, is a party to a sale leaseback transaction that did not meet the criteria for sale leaseback accounting. This transaction was accounted for as a financing arrangement over the course of the lease agreement. The obligations mature in varying dates through 2058, require monthly interest and principal payments, and bear interest at 11.865%. As of December 31, 2024 and 2023, the balance of the sale leaseback financing obligation was $85 million.
Lease-related financing obligations also include finance lease obligations of $47 million and $9 million as of December 31, 2024 and 2023, respectively. See further discussion in Note 13.
Fair Value of Debt
The aggregate estimated fair value and carrying amount of our consolidated debt obligations as of December 31, 2024 were $7.45 billion and $7.49 billion, respectively. As of December 31, 2023, the aggregate fair value and carrying amount of our
consolidated debt obligations were $3.48 billion and $3.58 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.

Revenue from Contract with Customer [Text Block] Revenue
Disaggregation of Revenue
Revenues from our Fuel Distribution segment are derived from the sale of fuel, non-fuel and lease income. Fuel sales consist primarily of the sale of motor fuel under supply agreements with third-party customers and affiliates. Fuel supply contracts with our customers generally provide that we distribute motor fuel at a price based on a formula which includes published rates, volume-based profit margin and other terms specific to the agreement. The customer is invoiced the agreed-upon price with most payment terms ranging less than 30 days. If the consideration promised in a contract includes a variable amount, the Partnership estimates the variable consideration amount and factors in such estimate to determine the transaction price under the expected value method. Revenue is recognized under the motor fuel contracts at the point in time the customer takes control of the fuel. At the time control is transferred to the customer the sale is considered final, because the agreements do not grant customers the right to return motor fuel. To determine when control transfers to the customer, the shipping terms of the contract are assessed as a primary indicator of the transfer of control. For FOB shipping point terms, revenue is recognized at the time of shipment. The performance obligation with respect to the sale of goods is satisfied at the time of shipment since the customer gains control at this time under the terms. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. Once the goods are shipped, the Partnership is precluded from redirecting the shipment to another customer and revenue is recognized. Non-fuel revenue includes merchandise revenue that comprises the in-store merchandise and food service sales at company-operated retail stores and other revenue such as credit card processing, car washes, lottery and other services. Lease revenue is derived from the leasing or subleasing of real estate used in the retail distribution of motor fuels.
Revenues from our Pipeline Systems segment are derived from interstate and intrastate pipeline transportation of refined products, crude oil and anhydrous ammonia and the applicable pipeline tariff on a per barrel basis for crude oil or refined products and on a per ton basis for ammonia.
Revenues from our Terminals segment include fees for tank storage agreements, under which a customer agrees to pay for a certain amount of storage in a tank over a period of time (storage terminal revenues) and throughput agreements, under which a customer pays a fee per barrel for volumes moving through our terminals (throughput terminal revenues). Our terminals also provide blending, additive injections, handling and filtering services for which we charge additional fees. Additionally, we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment. We recognized
lease revenues from these leases of $31 million for the year ended December 31, 2024, which are included in "Service revenue" in our consolidated statement of operations.

Contract Balances with Customers
The Partnership satisfies its performance obligations by transferring goods or services in exchange for consideration from customers. The timing of performance may differ from the timing the associated consideration is paid to or received from the customer, thus resulting in the recognition of a contract asset or a contract liability.
The Partnership recognizes a contract asset when making upfront consideration payments to certain customers. The upfront considerations represent a pre-paid incentive, as these payments are not made for distinct goods or services provided by the customer. The pre-payment incentives are recognized as a contract asset upon payment and amortized as a reduction of revenue over the term of the specific agreement.
The Partnership recognizes a contract liability if the customer’s payment of consideration precedes the Partnership’s fulfillment of the performance obligations, which primarily result from contracts with an incentive pricing structure, contributions in aid of construction (“CIAC”) payments (as discussed below), and contracts with minimum volume commitment We maintain some franchise agreements requiring dealers to make one-time upfront payments for long-term license agreements. The Partnership recognizes a contract liability when the upfront payment is received and recognizes revenue over the term of the license.
The balances of the Partnership’s contract assets and contract liabilities as of December 31, 2024 and 2023 were as follows:

Costs to Obtain or Fulfill a Contract
The Partnership recognizes an asset from the costs incurred to obtain a contract (e.g. sales commissions) only if it expects to recover those costs. On the other hand, the costs to fulfill a contract are capitalized if the costs are specifically identifiable to a contract, would result in enhancing resources that will be used in satisfying performance obligations in the future, and are expected to be recovered. These capitalized costs are recorded as a part of other current assets and other non-current assets on our consolidated balance sheets and are amortized as a reduction of revenue on a systematic basis consistent with the pattern of transfer of the goods or services to which such costs relate. The amount of amortization on these capitalized costs that the Partnership recognized in the years ended December 31, 2024, 2023 and 2022 was $35 million, $29 million and $22 million,
respectively. The Partnership has also made a policy election of expensing the costs to obtain a contract, as and when they are incurred, in cases where the expected amortization period is one year or less.
Performance Obligations
At contract inception, the Partnership assesses the goods and services promised in its contracts with customers and identifies a performance obligation for each promise to transfer a good or service (or bundle of goods or services) that is distinct. To identify the performance obligations, the Partnership considers all the goods or services promised in the contract, whether explicitly stated or implied based on customary business practices. For a contract that has more than one performance obligation, the Partnership allocates the total contract consideration to each distinct performance obligation on a relative standalone selling price basis. Revenue is recognized when (or as) the performance obligations are satisfied, that is, when the customer obtains control of the good or the service is provided.
The Partnership distributes fuel under long-term contracts to branded distributors, branded and unbranded third-party dealers and branded and unbranded retail fuel outlets. Sunoco-branded supply contracts with distributors generally have both time and volume commitments that establish contract duration. These contracts have an initial term of approximately ten years, with an estimated, volume-weighted term remaining of approximately five years.
The Partnership is party to a 15-year take-or-pay fuel supply agreement with 7-Eleven, Inc. and SEI Fuel Services, Inc. (collectively, the “Distributor”) in which the Distributor is required to purchase a volume of fuel that provides the Partnership a minimum amount of gross profit annually. We expect to recognize this revenue in accordance with the contract as we transfer control of the product to the customer. However, in case of an annual shortfall we will recognize the amount payable by the Distributor at the sooner of the time at which the Distributor makes up the shortfall or becomes contractually or operationally unable to do so. The transaction price of the contract is variable in nature, fluctuating based on market conditions. The Partnership has elected to take the practical expedient not to estimate the amount of variable consideration allocated to wholly unsatisfied performance obligations. 7-Eleven, Inc. accounted for approximately 18% and 20% of total revenues for the years ended December 31, 2024 and 2023, respectively.
In some contractual arrangements, the Partnership grants dealers a franchise license to operate the Partnership’s retail stores over the life of a franchise agreement. In return for the grant of the retail store license, the dealer makes a one-time nonrefundable franchise fee payment to the Partnership plus sales based royalties payable to the Partnership at a contractual rate during the period of the franchise agreement. Under the requirements of ASC Topic 606, the franchise license is deemed to be a symbolic license for which recognition of revenue over time is the most appropriate measure of progress toward complete satisfaction of the performance obligation. Revenue from this symbolic license is recognized evenly over the life of the franchise agreement.
In certain instances, our customers reimburse us for capital projects, in arrangements referred to as CIAC. Typically, in these instances, we receive upfront payments for future services, which are included in the transaction price of the underlying service contract.
Remaining Performance Obligations

Practical Expedients Selected by the Partnership
The Partnership elected the following practical expedients in accordance with ASC 606:
•Significant financing component - The Partnership elected not to adjust the promised amount of consideration for the effects of a significant financing component if the Partnership expects at contract inception that the period between the transfer of a promised good or service to a customer and when the customer pays for that good or service will be one year or less.
•Incremental costs of obtaining a contract - The Partnership elected to expense the incremental costs of obtaining a contract when the amortization period for such contracts would have been one year or less.
•Shipping and handling costs - The Partnership elected to account for shipping and handling activities that occur after the customer has obtained control of a good as fulfillment activities (i.e., an expense) rather than as a promised service.
•Measurement of transaction price - The Partnership has elected to exclude from the measurement of transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Partnership from a customer (i.e., sales tax, value added tax, etc.).
•Variable consideration of wholly unsatisfied performance obligations - The Partnership has elected to exclude the estimate of variable consideration to the allocation of wholly unsatisfied performance obligations.

Lessee Accounting
The Partnership leases retail stores, other property and equipment under non-cancellable operating leases whose initial terms are typically five to 30 years, with some having a term of 40 years or more, along with options that permit renewals for additional periods. At the inception of each, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify leased assets as operating or finance under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on our consolidated balance sheets.
At this time, the majority of active leases within our portfolio are classified as operating leases. Operating leases are included in operating lease right-of-use assets, net, operating lease current liabilities and operating lease non-current liabilities on our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in other non-current assets and long-term debt, net on our consolidated balance sheets. The right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make minimum lease payments arising from the lease for the duration of the lease term.
Most leases include one or more options to renew, with renewal terms that can extend the lease term from one year to 20 years or greater. The exercise of lease renewal options is typically at our discretion. Additionally, many leases contain early termination clauses, however early termination typically requires the agreement of both parties to the lease. At lease inception, all renewal options reasonably certain to be exercised are considered when determining the lease term. At this time, the Partnership does not have leases that include options to purchase or automatic transfer of ownership of the leased property to the Partnership. The depreciable life of leased assets and leasehold improvements are limited by the expected lease term.
To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. At this time, many of our leases do not provide an implicit rate, therefore to determine the present value of minimum lease payments we use our incremental borrowing rate based on the information available at lease commencement date. The right-of-use assets also include any lease payments made and exclude lease incentives.
Minimum rent payments are expensed on a straight-line basis over the term of the lease. In addition, some leases may require additional contingent or variable lease payments based on factors specific to the individual agreement. Variable lease payments we are typically responsible for include payment of real estate taxes, maintenance expenses and insurance.

The Partnership leases or subleases a portion of its real estate portfolio to third-party companies as a stable source of long-term revenue. Our lessor and sublease portfolio consists mainly of operating leases with convenience store operators. At this time, most lessor agreements contain five-year terms with renewal options to extend and early termination options based on established terms specific to the individual agreement. Additionally, we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment.
Minimum future lease payments receivable as of December 31, 2024 were as follows:

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
We are subject to various federal, state and local environmental laws and make financial expenditures in order to comply with regulations governing underground storage tanks adopted by federal, state and local regulatory agencies. In particular, at the federal level, the Resource Conservation and Recovery Act of 1976, as amended, requires the EPA to establish a comprehensive regulatory program for the detection, prevention and cleanup of leaking underground storage tanks (e.g. overfills, spills and underground storage tank releases).
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 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 2024, 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. Accordingly, we have recorded estimated undiscounted liabilities for these sites totaling $28 million and $18 million as of December 31, 2024 and 2023, respectively, which are classified as accrued expenses and other current liabilities and other non-current liabilities.

Income Tax Income Tax Expense
As a partnership, we are generally not subject to federal income tax and most state income taxes. However, the Partnership conducts certain activities through corporate subsidiaries which are subject to federal and state income taxes.
The Partnership’s income before income tax expense by geographic area is shown in the table below:

As of December 31, 2024, Sunoco Retail, a corporate subsidiary of the Partnership, had a state net operating loss carryforward of $20 million, which we expect to fully utilize. Sunoco Retail has no federal net operating loss carryforward. A foreign subsidiary of Sunoco Retail LLC had a net operating loss carryforward of $56 million, which we expect to fully utilize.    
As of December 31, 2024, we had $11 million ($8 million after federal income tax benefits) related to tax positions which, if recognized, would impact our effective tax rate. We did not recognize any changes in unrecognized tax benefits in 2024, 2023 or 2022.
We accrue interest and penalties on income tax underpayments (overpayments) as a component of income tax expense. During 2024, we recognized interest and penalties of $1 million. At December 31, 2024, we had interest and penalties accrued of $4 million, net of taxes.
The IRS is auditing a 2018 income tax refund claim filed by a wholly owned subsidiary of the Partnership. In general, the Partnership and its subsidiaries are no longer subject to examination by the IRS and most state jurisdictions for 2018 and prior years.

Allocation of Net Income
Our Partnership Agreement contains provisions for the allocation of net income and loss to the unitholders. For purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100% to Energy Transfer.
The calculation of net income allocated to common unitholders 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.
Incentive Distribution Rights
The following table illustrates the percentage allocations of available cash from operating surplus between our common unitholders and the holder of our IDRs based on the specified target distribution levels, after the payment of distributions to Class C unitholders. The amounts set forth under “marginal percentage interest in distributions” are the percentage interests of our IDR holder and the common unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “total quarterly distribution per common unit target amount.” The percentage interests shown for our common unitholders and our IDR holder for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. Energy Transfer currently owns our IDRs.

Retirement Benefits [Abstract]  
Unit-Based Compensation Unit-Based Compensation
The Partnership has issued phantom units to its employees and non-employee directors, which vest 60% after three years and 40% after five years. Phantom units have the right to receive distributions prior to vesting. The fair value of these units is the market price of our common units on the grant date, and is amortized over the five-year vesting period using the straight-line method. Unit-based compensation expense related to the Partnership included in our consolidated statements of operations and comprehensive income was $17 million, $17 million and $14 million for the years ended December 31, 2024, 2023 and 2022, respectively. The total fair value of phantom units vested for the years ended December 31, 2024, 2023 and 2022, was $23 million, $30 million and $22 million, respectively, based on the market price of SUN’s common units as of the vesting date.
Unrecognized compensation expenses related to our unvested phantom units totaled $43 million as of December 31, 2024, which are expected to be recognized over a weighted average period of 4 years. The fair value of unvested phantom units outstanding as of December 31, 2024 and 2023, totaled $86 million and $96 million, respectively.
Phantom unit award activity for the years ended December 31, 2024 and 2023 consisted of the following:

Cash Restricted Units. Beginning in 2024, the Partnership also granted cash restricted units, which vest through three years of service. A cash restricted unit entitles the award recipient to receive cash equal to the market value of one SUN Common Unit upon vesting. For the year ended December 31, 2024, the Partnership granted a total of 134,225 cash restricted units, all of which were unvested as of December 31, 2024.
Retirement Benefits Employee Benefit Plans
Pension and Other Postretirement Benefits
The NuStar Pension Plan (the “Pension Plan”) is a qualified non-contributory defined benefit pension plan that provided certain eligible NuStar employees with retirement income as calculated under a cash balance formula. Under the cash balance formula, benefits were determined based on age, years of vesting service and interest credits, and employees become fully vested in their benefits upon attaining three years of vesting service.
NuStar also maintained an excess pension plan (the “Excess Pension Plan”), which is a non qualified deferred compensation plan that provides benefits to a select group of management or other highly compensated employees. Neither the Excess Thrift Plan nor the Excess Pension Plan is intended to constitute either a qualified plan under the provisions of Section 401 of the Code or a funded plan subject to the Employee Retirement Income Security Act.
The Pension Plan and Excess Pension Plan are collectively referred to as the “Pension Plans” in the tables and discussion below. Other postretirement benefit plans include NuStar’s contributory medical benefits plan for U.S. employees who retired prior to April 1, 2014 and, for employees who retire on or after April 1, 2014, a partial reimbursement for eligible third-party health care premiums. We use December 31 as the measurement date for our pension and other postretirement plans.
We made no contributions to the Pension Plans subsequent to the NuStar acquisition, and the Pension Plan was terminated on November 30, 2024.
The changes in the benefit obligation, the changes in fair value of plan assets, the funded status and the amounts recognized in the consolidated balance sheets for our Pension Plans and other postretirement benefit plans as of December 31, 2024 were as follows:

The actuarial loss related to the benefit obligation for our pension plans was primarily attributable to the termination of the Pension Plan. The fair value of our plan assets is affected by the return on plan assets resulting primarily from the performance of equity and bond markets during the period.
The Excess Pension Plan has no plan assets and an accumulated benefit obligation of $1 million as of December 31, 2024. The accumulated benefit obligation is the present value of benefits earned to date, while the projected benefit obligation may include future salary increase assumptions. The projected benefit obligation for the Excess Pension Plan was $1 million as of December 31, 2024.

The components of net periodic benefit cost for the period from the NuStar acquisition (May 3, 2024) to December 31, 2024 related to our Pension Plans and other postretirement benefit plans were as follows:

We amortize prior service costs and credits on a straight-line basis over the average remaining service period of employees expected to receive benefits under our Pension Plans and other postretirement benefit plans (“Prior service amortization” in table above). We amortize the actuarial gains and losses that exceed 10% of the greater of the projected benefit obligation or market-related value of plan assets (smoothed asset value) over the average remaining service period of active employees expected to receive benefits under our Pension Plans and other postretirement benefit plans (“Actuarial gain amortization” in table above).
The service cost component of net periodic benefit cost is reported in “General and administrative” expenses and “Other Operating” expenses on the consolidated statements of operations, and the remaining components of net periodic benefit cost are reported in “Other, net.”
Fair Value of Plan Assets
We disclose the fair value for each major class of plan assets in the Pension Plan in three levels: Level 1, defined as observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets that are not active; and Level 3, defined as unobservable inputs for which little or no market data exists.

The discount rate is based on a hypothetical yield curve represented by a series of annualized individual discount rates. Each bond issue underlying the hypothetical yield curve required an average rating of double-A, when averaging all available ratings by Moody’s Investor Service Inc., S&P Global Ratings and Fitch Ratings. The expected long-term rate of return on plan assets is based on the weighted averages of the expected long-term rates of return for each asset class of investments held in our plans as determined using historical data and the assumption that capital markets are informationally efficient. The expected rate of compensation increase represents average long-term salary increases.

Segment Reporting Segment Reporting
Description of Segments
Our consolidated financial statements reflect three reportable segments: Fuel Distribution, Pipeline Systems and Terminals.
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 Hawaii and New Jersey.
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 our J.C. Nolan joint venture), approximately 6,000 miles of crude oil pipeline (including the pipelines of ET-S Permian), approximately 2,000 miles of ammonia pipeline and 67 terminals.
Terminals. Our Terminals segment is composed of four transmix processing facilities and 56 refined product terminals (two in Europe, six in Hawaii and 48 in the continental United States).
Segment Operating Results
The Partnership evaluates performance and allocates resources for all of its reportable segments based on Segment Adjusted EBITDA.
The Partnership’s chief operating decision maker (“CODM”) is its chief operating officer. The CODM uses Segment Adjusted EBITDA to allocate resources (including employees, property, and financial or capital resources) for each segment predominantly in the annual budget and forecasting process. The CODM considers forecast-to-actual variances on a monthly basis when making decisions about allocating capital and personnel to the segments. The CODM also uses Segment Adjusted EBITDA to assess the performance for each segment by comparing the results and return on assets of each segment with one another and in the compensation of certain employees.
The Partnership’s reportable segments are business units that offer different products and services. The reportable segments are each managed separately because they provide different services and products.
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 and impairment charges, unrealized gains and losses on commodity derivatives, inventory adjustments 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 years ended December 31, 2024, 2023 and 2022.

Earnings Per Share [Abstract]  
Net Income per Unit Net Income per Common Unit
Net income per common unit is computed by dividing common unitholders’ interest in net income by the weighted average number of outstanding common units. Our net income is allocated to common unitholders in accordance with their respective partnership percentages, after giving effect to any priority income allocations for incentive distributions and distributions on employee unit awards. Earnings in excess of distributions are allocated to common unitholders based on their respective ownership interests. Payments made to our common unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit.
In addition to the common units, we identify the IDRs as participating securities and use the two-class method when calculating net income per unit applicable to limited partners, which is based on the weighted average number of common units outstanding during the period. Diluted net income per unit includes the effects of potentially dilutive units on our common units, consisting of unvested phantom units.
A reconciliation of the numerators and denominators of the basic and diluted per unit computations is as follows:

Accounting Policies [Abstract]  
Use of Estimates
Use of Estimates
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurements
Fair Value Measurements
We use fair value measurements to measure, among other items, purchased assets, investments, leases and derivative contracts. We also use them to assess impairment of properties, equipment, intangible assets and goodwill. An asset’s fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters, or is derived from such prices or parameters. Where observable prices or inputs are not available, unobservable prices or inputs are used to estimate the current fair value, often using an internal valuation model. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the item being valued.
ASC 820 “Fair Value Measurements and Disclosures” prioritizes the inputs used in measuring fair value into the following hierarchy:
Level 1    Quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2    Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable;
Level 3    Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.
Cash, accounts receivable, certain other current assets, marketable securities, accounts payable, accrued expenses and certain other current liabilities are reflected in the consolidated balance sheets at carrying amounts, which approximate the fair value due to their short term nature.
Segment Reporting
Segment Reporting
We operate our business in three reportable segments: Fuel Distribution, Pipeline Systems and Terminals. 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 Hawaii and New Jersey. Our Pipeline Systems segment includes an integrated pipeline and terminal network comprised of refined product, crude oil and ammonia pipelines and terminals, including our investments in the J.C. Nolan and ET-S Permian joint ventures. Our Terminals segment is composed of four transmix processing facilities and 56 refined product terminals (two in Europe, six in Hawaii and 48 in the continental United States).
Acquisition Accounting
Acquisition Accounting
Acquisitions of assets or entities that include inputs and processes and have the ability to create outputs are accounted for as business combinations. A purchase price allocation is recorded for tangible and intangible assets acquired and liabilities assumed based on their fair value. The excess of fair value of consideration conveyed over fair value of net assets acquired is recorded as goodwill. The consolidated statements of operations and comprehensive income for the periods presented include the results of operations for each acquisition from their respective dates of acquisition.
Cash and Cash Equivalents
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.
Sunoco, LLC and Sunoco Retail LLC, our indirect wholly owned subsidiary that is subject to state and federal income tax (“Sunoco Retail”), have treasury services agreements with Energy Transfer (R&M), LLC, an indirect wholly owned subsidiary of Energy Transfer, for certain cash management activities. The net balance of Sunoco LLC and Sunoco Retail activity is reflected in either “Advances to affiliates” or “Advances from affiliates” on the consolidated balance sheets.
Accounts Receivable
Accounts Receivable
The majority of trade receivables are from wholesale fuel customers or from credit card companies related to retail credit card transactions. Wholesale customer credit is extended based on an evaluation of the customer’s financial condition. We maintain allowances for expected credit losses based on the best estimate of the amount of expected credit losses in existing accounts receivable. Credit losses are recorded against the allowance when accounts are deemed uncollectible.
Receivables from affiliates arise from fuel sales and other miscellaneous transactions with non-consolidated affiliates. These receivables are recorded at face value, without interest or discount.
7-Eleven, Inc. is the only third-party dealer or distributor which is individually over 10% of our Fuel Distribution segment or individually over 10%, in terms of revenue, of our aggregate business.
Inventories
Inventories
Fuel inventories are stated at the lower of cost or market using the last-in, first-out method (“LIFO”). Under this methodology, the cost of fuel sold consists of actual acquisition costs, which includes transportation and storage costs. Such costs are adjusted to reflect increases or decreases in inventory quantities which are valued based on changes in LIFO inventory layers.
Merchandise inventories are stated at the lower of average cost, as determined by the retail inventory method, or market. We record an allowance for shortages and obsolescence relating to merchandise inventory based on historical trends and any known changes. Shipping and handling costs are included in the cost of merchandise inventories.
Advertising Costs
Advertising Costs
Advertising costs are expensed as incurred. Advertising costs were $30 million, $26 million and $25 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Property and Equipment
Property and Equipment
Property and equipment are recorded at cost. Depreciation is computed on a straight-line basis over the useful lives of assets. Assets under finance leases are depreciated over the life of the corresponding lease.
Amortization of leasehold improvements is based upon the shorter of the remaining terms of the leases including renewal periods that are reasonably assured, or the estimated useful lives, which approximate twenty years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Maintenance and repairs are charged to operations as incurred. Gains or losses on the disposition of property and equipment are recorded in the period incurred.
Long-Lived Assets and Assets Held for Sale
Long-Lived Assets and Assets Held for Sale
Long-lived assets are tested for possible impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. If such indicators exist, the estimated undiscounted future cash flows related to the asset are compared to the carrying value of the asset. If the carrying value is greater than the estimated undiscounted future cash flows, an
impairment charge is recorded in the consolidated statements of operations and comprehensive income for amounts necessary to reduce the corresponding carrying value of the asset to fair value. The impairment loss calculations require management to apply judgment in estimating future cash flows.
Properties that have been closed and other excess real property are recorded as assets held for sale, and are written down to the lower of cost or estimated net realizable value at the time we close such stores or determine that these properties are in excess and intend to offer them for sale. We estimate the net realizable value based on our experience in utilizing or disposing of similar assets and on estimates provided by our own and third-party real estate experts. Although we have not experienced significant changes in our estimate of net realizable value, changes in real estate markets could significantly impact the net values realized from the sale of assets.
Goodwill and Indefinite-Lived Intangible Assets
Goodwill and Indefinite-Lived Intangible Assets
Goodwill represents the excess of consideration paid over fair value of net assets acquired. Goodwill and intangible assets acquired in a purchase business combination are recorded at fair value as of the date acquired. Acquired intangible assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment at least annually, or more frequently if events and circumstances indicate that the asset might be impaired. The annual impairment test of goodwill and indefinite lived intangible assets is performed as of the first day of the fourth quarter of each fiscal year.
The Partnership uses qualitative factors to determine whether it is more likely than not (likelihood of more than 50%) that the fair value of a reporting unit exceeds its carrying amount, including goodwill. Some of the qualitative factors considered in applying this test include consideration of macroeconomic conditions, industry and market conditions, cost factors affecting the business, overall financial performance of the business and performance of the unit price of the Partnership.
If qualitative factors are not deemed sufficient to conclude that the fair value of the reporting unit more likely than not exceeds its carrying value, then a quantitative approach is applied in making an evaluation. The quantitative evaluation utilizes multiple valuation methodologies, including a market approach (market price multiples of comparable companies), an income approach (discounted cash flow analysis), or a weighted combination of these methods. The computations require management to make significant estimates and assumptions, including, among other things, selection of comparable publicly traded companies, the discount rate applied to future earnings reflecting a weighted average cost of capital and earnings growth assumptions. The Partnership believes the estimates and assumptions used in our impairment assessments are reasonable and based on available market information, but variations in any of the assumptions could result in materially different calculations of fair value and determinations of whether or not an impairment is indicated. A discounted cash flow analysis requires management to make various assumptions about future sales, operating margins, capital expenditures, working capital and growth rates. Cash flow projections are derived from one-year budgeted amounts plus an estimate of later period cash flows, all of which are determined by management. Subsequent period cash flows are developed for each reporting unit using growth rates that management believes are reasonably likely to occur. Under the guideline company method, the Partnership determined the estimated fair value of each of our reporting units by applying valuation multiples of comparable publicly-traded companies to each reporting unit’s projected EBITDA and then averaging that estimate with similar historical calculations using a three-year average. In addition, the Partnership estimated a reasonable control premium representing the incremental value that accrues to the majority owner from the opportunity to dictate the strategic and operational actions of the business. If the evaluation results in the fair value of the reporting unit being lower than the carrying value, an impairment charge is recorded.
Indefinite-lived intangible assets are composed of certain tradenames and liquor licenses which are not amortized but are evaluated for impairment annually or more frequently if events or changes occur that suggest an impairment in carrying value, such as a significant adverse change in the business climate. Indefinite-lived intangible assets are evaluated for impairment by comparing each asset’s fair value to its book value. Management first determines qualitatively whether it is more likely than not that an indefinite‑lived asset is impaired. If management concludes that it is more likely than not that an indefinite-lived asset is impaired, then its fair value is determined by using the discounted cash flow model based on future revenues estimated to be derived in the use of the asset.
Other Intangible Assets
Other Intangible Assets
Other finite-lived intangible assets consist of supply agreements, customer relations, non-compete agreements and loan origination costs. Separable intangible assets that are not determined to have an indefinite life are amortized over their useful lives and assessed for impairment only if and when circumstances warrant. Determination of an intangible asset’s fair value and estimated useful life are based on an analysis of pertinent factors including: (1) the use of widely-accepted valuation approaches, such as the income approach or the cost approach, (2) the expected use of the asset by the Partnership, (3) the expected useful life of related assets, (4) any legal, regulatory or contractual provisions, including renewal or extension periods that would cause substantial costs or modifications to existing agreements and (5) the effects of obsolescence, demand, competition and other economic factors. Should any of the underlying assumptions indicate that the value of the intangible assets might be impaired, we may be required to reduce the carrying value and remaining useful life of the asset. If the underlying assumptions governing the
amortization of an intangible asset were later determined to have significantly changed, we may be required to adjust its amortization period to reflect a new estimate of its useful life. Any write-down of the value or unfavorable change in the useful life of an intangible asset would increase expense at that time.
Customer relations and supply agreements are amortized on a straight-line basis over the remaining terms of the agreements, which generally range from five to twenty years. Non-compete agreements are amortized over the terms of the respective agreements.
Asset Retirement Obligations
Asset Retirement Obligations
The estimated future cost to remove an underground storage tank is recognized over the estimated useful life of the storage tank. We record a discounted liability for the future fair value of an asset retirement obligation along with a corresponding increase to the carrying value of the related long-lived asset at the time an underground storage tank is installed. We then depreciate the amount added to property and equipment and recognize accretion expense in connection with the discounted liability over the remaining life of the tank. We base our estimates of the anticipated future costs for tank removal on our prior experience with removals. We review assumptions for computing the estimated liability for tank removal on an annual basis. Any change in estimated cash flows are reflected as an adjustment to both the liability and the associated asset.
Long-lived assets related to asset retirement obligations aggregated $12 million and $13 million as of December 31, 2024 and 2023, respectively, and were reflected as property and equipment, net, on our consolidated balance sheets.
Environmental Liabilities
Environmental Liabilities
Environmental expenditures related to existing conditions, resulting from past or current operations and from which no current or future benefit is discernible, are expensed. Expenditures that extend the life of the related property or prevent future environmental contamination are capitalized. We determine and establish a liability on a site-by-site basis when future environmental expenditures are probable and can be reasonably estimated. A related receivable is recorded for estimable and probable reimbursements.
Revenue Recognition
Revenue Recognition
Revenues from our Fuel Distribution segment are derived from the sale of fuel, non-fuel and lease income. Fuel sales consist primarily of the sale of motor fuel under supply agreements with third-party customers and affiliates. Fuel supply contracts with our customers generally provide that we distribute motor fuel at a price based on a formula which includes published rates, volume-based profit margin and other terms specific to the agreement. The customer is invoiced the agreed-upon price with most payment terms ranging less than 30 days. If the consideration promised in a contract includes a variable amount, the Partnership estimates the variable consideration amount and factors in such estimate to determine the transaction price under the expected value method. Revenue is recognized under the motor fuel contracts at the point in time the customer takes control of the fuel. At the time control is transferred to the customer the sale is considered final, because the agreements do not grant customers the right to return motor fuel. To determine when control transfers to the customer, the shipping terms of the contract are assessed as a primary indicator of the transfer of control. For free on board (“FOB”) shipping point terms, revenue is recognized at the time of shipment. The performance obligation with respect to the sale of goods is satisfied at the time of shipment since the customer gains control at this time under the terms. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. Once the goods are shipped, the Partnership is precluded from redirecting the shipment to another customer and revenue is recognized. Non-fuel revenue includes merchandise revenue that comprises the in-store merchandise and food service sales at company-operated retail stores and other revenue such as credit card processing, car washes, lottery and other services. Lease revenue is derived from leasing arrangements for which we are the lessor and recognized ratably over the term of the underlying lease.
Revenues from our Pipeline Systems segment are derived from interstate and intrastate pipeline transportation of refined products, crude oil and anhydrous ammonia and the applicable pipeline tariff on a per barrel basis for crude oil or refined products and on a per ton basis for ammonia.
Revenues from our Terminals segment include fees for tank storage agreements, under which a customer agrees to pay for a certain amount of storage in a tank over a period of time and throughput agreements, under which a customer pays a fee per barrel for volumes moving through our terminals. Our terminals also provide blending, additive injections, handling and filtering services for which we charge additional fees.
Lease Income
Lease Income
Lease income from leasing or subleasing of real estate is recognized on a straight-line basis over the term of the lease.
Lessor Accounting
The Partnership leases or subleases a portion of its real estate portfolio to third-party companies as a stable source of long-term revenue. Our lessor and sublease portfolio consists mainly of operating leases with convenience store operators. At this time, most lessor agreements contain five-year terms with renewal options to extend and early termination options based on established terms specific to the individual agreement. Additionally, we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment.
Cost of Sales
Cost of Sales
We include in cost of sales all costs incurred to acquire fuel and merchandise, including the costs of purchasing, storing and transporting inventory prior to delivery to our customers. Items are removed from inventory and are included in cost of sales based on the retail inventory method for merchandise and the LIFO method for motor fuel. Cost of sales does not include depreciation of property and equipment as amounts attributed to cost of sales would not be significant. Depreciation is classified within operating expenses in the consolidated statements of operations and comprehensive income.
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 $164 million, $274 million and $285 million for the years ended December 31, 2024, 2023 and 2022, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in our consolidated statements of operations and comprehensive income.
Deferred Branding Incentives
Deferred Branding Incentives
We receive payments for branding incentives related to fuel supply contracts. Unearned branding incentives are deferred and amortized on a straight-line basis over the term of the agreement as a credit to cost of sales.
Lease Accounting
Lease Accounting
At the inception of each lease arrangement, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify lease assets as operating or finance leases under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on our consolidated balance sheets.
Balances related to operating leases are included in operating lease right-of-use assets, net, operating lease current liabilities and non-current operating lease liabilities on our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in other non-current assets and long-term debt, net on our consolidated balance sheets. The right-of-use assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the obligation of the Partnership to make minimum lease payments arising from the lease for the duration of the lease term.
The Partnership leases a portion of its properties under non-cancelable operating leases, whose initial terms are typically five to fifteen years, with options permitting renewal for additional periods. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or greater. The exercise of lease renewal options is typically at the sole discretion of the Partnership and lease extensions are evaluated on a lease-by-lease basis. Leases containing early termination clauses typically require the agreement of both parties to the lease. At the inception of a lease, all renewal options reasonably certain to be exercised are considered when determining the lease term. The depreciable life of lease assets and leasehold improvements are limited by the expected lease term.
To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. Presently, because many of our leases do not provide an implicit rate, the Partnership applies its incremental borrowing rate based on the information available at the lease commencement date to determine the present value of minimum lease payments. The operating and finance lease right-of-use assets include any lease payments made and exclude lease incentives.
Minimum rent is expensed on a straight-line basis over the term of the lease, including renewal periods that are reasonably assured at the inception of the lease. The Partnership is typically responsible for payment of real estate taxes, maintenance expenses and insurance. The Partnership also leases certain vehicles, and such leases are typically less than five years.
For short-term leases (leases that have term of 12 months or less upon commencement), lease payments are recognized on a straight-line basis and no right-of-use assets are recorded.
Lessee Accounting
The Partnership leases retail stores, other property and equipment under non-cancellable operating leases whose initial terms are typically five to 30 years, with some having a term of 40 years or more, along with options that permit renewals for additional periods. At the inception of each, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify leased assets as operating or finance under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on our consolidated balance sheets.
At this time, the majority of active leases within our portfolio are classified as operating leases. Operating leases are included in operating lease right-of-use assets, net, operating lease current liabilities and operating lease non-current liabilities on our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in other non-current assets and long-term debt, net on our consolidated balance sheets. The right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make minimum lease payments arising from the lease for the duration of the lease term.
Most leases include one or more options to renew, with renewal terms that can extend the lease term from one year to 20 years or greater. The exercise of lease renewal options is typically at our discretion. Additionally, many leases contain early termination clauses, however early termination typically requires the agreement of both parties to the lease. At lease inception, all renewal options reasonably certain to be exercised are considered when determining the lease term. At this time, the Partnership does not have leases that include options to purchase or automatic transfer of ownership of the leased property to the Partnership. The depreciable life of leased assets and leasehold improvements are limited by the expected lease term.
To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. At this time, many of our leases do not provide an implicit rate, therefore to determine the present value of minimum lease payments we use our incremental borrowing rate based on the information available at lease commencement date. The right-of-use assets also include any lease payments made and exclude lease incentives.
Minimum rent payments are expensed on a straight-line basis over the term of the lease. In addition, some leases may require additional contingent or variable lease payments based on factors specific to the individual agreement. Variable lease payments we are typically responsible for include payment of real estate taxes, maintenance expenses and insurance.
Earnings Per Unit
Earnings Per Unit
In addition to limited partner units, we have IDRs as participating securities and compute net income per common unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Second Amended and Restated Agreement of Limited Partnership, as may be amended from time to time (the “Partnership Agreement”). Net income per unit applicable to limited partners is computed by
dividing limited partners’ interest in net income, after deducting any incentive distributions and distributions on unvested phantom unit awards, by the weighted average number of outstanding common units.
Stock and Unit-based Compensation
Unit-Based Compensation
Under the Partnership's long-term incentive plans, various types of awards may be granted to employees, consultants and directors of our General Partner who provide services for us. Compensation expense related to outstanding awards is recognized over the vesting period based on the grant-date fair value. The grant-date fair value is determined based on the market price of our common units on the grant date. We amortize the grant-date fair value of these awards over their vesting period using the straight-line method. Expenses related to unit-based compensation are included in general and administrative expenses.
Income Taxes
Income Taxes
The Partnership is a publicly traded limited partnership and is not taxable for federal and most state income tax purposes. As a result, our earnings or losses, to the extent not included in a taxable subsidiary, for federal and most state purposes are included in the tax returns of the individual partners. Net earnings for financial statement purposes may differ significantly from taxable income reportable to Unitholders as a result of differences between the tax basis and financial basis of assets and liabilities, differences between the tax accounting and financial accounting treatment of certain items, and due to allocation requirements related to taxable income under our Partnership Agreement. We do not have access to information regarding each partner's individual tax basis in our limited partner interests.
As a publicly traded limited partnership, we are subject to a statutory requirement that our “qualifying income” (as defined by the Internal Revenue Code, related Treasury Regulations and IRS pronouncements) exceed 90% of our total gross income, determined on a calendar year basis. If our qualifying income were not to meet this statutory requirement, the Partnership would be taxed as a corporation for federal and state income tax purposes. For the years ended December 31, 2024, 2023 and 2022, our qualifying income met the statutory requirement.
The Partnership conducts certain activities through corporate subsidiaries which are subject to federal, state, local and foreign income taxes. The Partnership and its corporate subsidiaries account for income taxes under the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized.
The determination of the provision for income taxes requires significant judgment, use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our consolidated financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. When facts and circumstances change, we reassess these probabilities and record any changes through the provision for income taxes
Pension and Other Postretirement Plans, Pensions, Policy
Defined Benefit Plans
We estimate pension and other postretirement benefit obligations and costs based on actuarial valuations. The annual measurement date for our pension and other postretirement benefit plans is December 31. The actuarial valuations require the use of certain assumptions including discount rates, expected long-term rates of return on plan assets and expected rates of compensation increase. Changes in these assumptions are primarily influenced by factors outside of our control.
Foreign Currency Transactions and Translations Policy
Foreign Currency Translation
The functional currencies of our foreign subsidiaries are the local currencies of the countries in which the subsidiaries are located. The assets and liabilities of our foreign subsidiaries with local functional currencies are translated to U.S. dollars at period-end exchange rates, and income and expense items are translated to U.S. dollars at weighted-average exchange rates in effect during the period. These translation adjustments are included in accumulated other comprehensive income ("AOCI") in the equity section of the consolidated balance sheets. Upon the sale or liquidation of our investment in a foreign subsidiary, translation adjustments that have historically accumulated in AOCI related to that subsidiary are released from AOCI and reported as part of the gain or loss on sale. Gains and losses on foreign currency transactions are included in other income (expense), net in the consolidated statements of operations.
New Accounting Pronouncements, Policy
Recent Accounting Pronouncements
In November 2024, Financial Accounting Standards Board (“FASB”) 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.
In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 improves and enhances income tax disclosure requirements, including new disclosures related to tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and interim periods within annual periods beginning after December 15, 2025, with early adoption permitted. ASU 2023-09 is to be applied on a prospective basis, with retrospective application permitted. We are currently evaluating the impact, if any, of ASU 2023-09 on our consolidated financial statements and related disclosures.
Equity Method Investments Issuances, Policy
Investments in Unconsolidated Affiliates
We own interests in certain joint ventures with Energy Transfer that are accounted for by the equity method. In general, we use the equity method of accounting for an investment for which we exercise significant influence over, but do not control, the investee’s operating and financial policies. An impairment of an investment in an unconsolidated affiliate is recognized when circumstances indicate that a decline in the investment value is other-than-temporary.

Leases, Codification Topic 842 (Policies)
 12 Months Ended
Dec. 31, 2024
Leases [Abstract]  
Lease Income
Lease Income
Lease income from leasing or subleasing of real estate is recognized on a straight-line basis over the term of the lease.
Lessor Accounting
The Partnership leases or subleases a portion of its real estate portfolio to third-party companies as a stable source of long-term revenue. Our lessor and sublease portfolio consists mainly of operating leases with convenience store operators. At this time, most lessor agreements contain five-year terms with renewal options to extend and early termination options based on established terms specific to the individual agreement. Additionally, we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment.
Lease Accounting
Lease Accounting
At the inception of each lease arrangement, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify lease assets as operating or finance leases under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on our consolidated balance sheets.
Balances related to operating leases are included in operating lease right-of-use assets, net, operating lease current liabilities and non-current operating lease liabilities on our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in other non-current assets and long-term debt, net on our consolidated balance sheets. The right-of-use assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the obligation of the Partnership to make minimum lease payments arising from the lease for the duration of the lease term.
The Partnership leases a portion of its properties under non-cancelable operating leases, whose initial terms are typically five to fifteen years, with options permitting renewal for additional periods. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or greater. The exercise of lease renewal options is typically at the sole discretion of the Partnership and lease extensions are evaluated on a lease-by-lease basis. Leases containing early termination clauses typically require the agreement of both parties to the lease. At the inception of a lease, all renewal options reasonably certain to be exercised are considered when determining the lease term. The depreciable life of lease assets and leasehold improvements are limited by the expected lease term.
To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. Presently, because many of our leases do not provide an implicit rate, the Partnership applies its incremental borrowing rate based on the information available at the lease commencement date to determine the present value of minimum lease payments. The operating and finance lease right-of-use assets include any lease payments made and exclude lease incentives.
Minimum rent is expensed on a straight-line basis over the term of the lease, including renewal periods that are reasonably assured at the inception of the lease. The Partnership is typically responsible for payment of real estate taxes, maintenance expenses and insurance. The Partnership also leases certain vehicles, and such leases are typically less than five years.
For short-term leases (leases that have term of 12 months or less upon commencement), lease payments are recognized on a straight-line basis and no right-of-use assets are recorded.
Lessee Accounting
The Partnership leases retail stores, other property and equipment under non-cancellable operating leases whose initial terms are typically five to 30 years, with some having a term of 40 years or more, along with options that permit renewals for additional periods. At the inception of each, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify leased assets as operating or finance under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on our consolidated balance sheets.
At this time, the majority of active leases within our portfolio are classified as operating leases. Operating leases are included in operating lease right-of-use assets, net, operating lease current liabilities and operating lease non-current liabilities on our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in other non-current assets and long-term debt, net on our consolidated balance sheets. The right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make minimum lease payments arising from the lease for the duration of the lease term.
Most leases include one or more options to renew, with renewal terms that can extend the lease term from one year to 20 years or greater. The exercise of lease renewal options is typically at our discretion. Additionally, many leases contain early termination clauses, however early termination typically requires the agreement of both parties to the lease. At lease inception, all renewal options reasonably certain to be exercised are considered when determining the lease term. At this time, the Partnership does not have leases that include options to purchase or automatic transfer of ownership of the leased property to the Partnership. The depreciable life of leased assets and leasehold improvements are limited by the expected lease term.
To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. At this time, many of our leases do not provide an implicit rate, therefore to determine the present value of minimum lease payments we use our incremental borrowing rate based on the information available at lease commencement date. The right-of-use assets also include any lease payments made and exclude lease incentives.
Minimum rent payments are expensed on a straight-line basis over the term of the lease. In addition, some leases may require additional contingent or variable lease payments based on factors specific to the individual agreement. Variable lease payments we are typically responsible for include payment of real estate taxes, maintenance expenses and insurance.
