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, 2023, Energy Transfer and its subsidiaries owned 100% of the membership interests in our General Partner, all of our incentive distribution rights (“IDRs”) and approximately 33.7% of our common units, which constitutes a 28.2% limited partner interest in us.

We distribute motor fuels across more than 40 states and territories throughout the United States, including Hawaii and Puerto Rico. We also operate retail stores in Hawaii and New Jersey.

Our primary operations are conducted by the following consolidated subsidiaries:

•Sunoco, LLC (“Sunoco LLC”), a Delaware limited liability company, primarily distributes motor fuel in more than 40 states throughout the United States. Sunoco LLC also processes transmix and distributes refined product through its terminals in over 15 states.

•Sunoco Retail LLC (“Sunoco Retail”), a Pennsylvania limited liability company, owns and operates retail stores that sell motor fuel and merchandise primarily in New Jersey. Sunoco Retail also leases owned sites to commission agents who sell motor fuels to the motoring public on Sunoco Retail's behalf for a commission.

•Aloha Petroleum LLC, a Delaware limited liability company, distributes motor fuel and operates terminal facilities on the Hawaiian Islands.

•Aloha Petroleum, Ltd. (“Aloha”), a Hawaii corporation, owns and operates retail stores on the Hawaiian Islands and leases owned sites to commission agents who sell motor fuels to the motoring public on Aloha's behalf for a commission.

•Peerless Oil & Chemicals, Inc. (“Peerless”), a Delaware corporation, is a terminal operator that distributes fuel products to over 100 locations primarily within Puerto Rico.

The consolidated financial statements of Sunoco LP presented herein for the years ended December 31, 2023, 2022 and 2021, 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.

Certain items have been reclassified for presentation purposes to conform to the accounting policies of the consolidated entity. Additionally, certain prior period amounts have been reclassified to conform to the 2023 presentation. These reclassifications had no impact on income from operations, net income and comprehensive income, or the balance sheets or statements of cash flows.

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 our investments in the J.C. Nolan Terminal and the J.C. Nolan Pipeline. Our Terminals segment is composed of four transmix processing facilities and 42 refined product terminals.

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 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.

Inventories

Fuel inventories are stated at the lower of cost or market using the last-in-first-out (“LIFO”) method. 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 $26 million, $25 million and $22 million for the years ended December 31, 2023, 2022 and 2021, 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, estimated to be forty years for buildings, three to fifteen years for equipment and thirty years for storage tanks. 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.

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 $13 million and $14 million as of December 31, 2023 and 2022, 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 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 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 operating leases 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 $274 million, $285 million and $332 million for the years ended December 31, 2023, 2022 and 2021, 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 twelve 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 First Amended and Restated Agreement of Limited Partnership, as amended (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.

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

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, 2023, 2022 and 2021, 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. These corporate subsidiaries include Sunoco Retail, Aloha and Peerless. 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.

2024 Acquisitions and Divestitures

On January 22, 2024, we entered into a definitive agreement with NuStar Energy L.P. (“NuStar”) to acquire NuStar in an all-equity transaction valued at approximately $7.3 billion, including assumed debt. Under the terms of the agreement, NuStar common unitholders will receive 0.400 Sunoco common units for each NuStar common unit. 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 transaction is expected to close in the second quarter of 2024, subject to customary closing conditions.

On January 11, 2024, we entered into a definitive agreement with 7-Eleven, Inc. to sell 204 convenience stores located in West Texas, New Mexico, and Oklahoma for approximately $1.0 billion, including customary adjustments for fuel and merchandise inventory. As part of the sale, SUN will also amend its existing take-or-pay fuel supply agreement with 7-Eleven, Inc. to incorporate additional fuel gross profit. The transaction is expected to close promptly upon receipt of regulatory approvals and satisfaction of customary closing conditions.

On January 11, 2024, we announced that we will acquire liquid fuels terminals in Amsterdam, Netherlands and Bantry Bay, Ireland from Zenith Energy for €170 million including working capital. The transaction is expected to close in the first quarter of 2024, subject to customary closing conditions.

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

						November 30, 2022

The terminals have a combined storage capacity of approximately 14.8 million barrels and are located along the East Coast and in the greater Chicago market. Management, with the assistance of an independent valuation firm, determined the fair value of assets and liabilities at the date of the acquisition. The purchase price was primarily allocated to property and equipment.

Senior Notes

The terms of each tranche of the Partnership’s senior notes (the “Senior Notes”) are governed by indentures among the Partnership and Sunoco Finance Corp. (together, the “Issuers”), and certain other subsidiaries of the Partnership (the “Guarantors”) and U.S. Bank National Association, as trustee. The 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 Senior Notes and guarantees are unsecured and rank equally with all of the Issuers’ and each Guarantor’s existing and future senior obligations. The 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 Senior Notes.

On September 20, 2023, we and Sunoco Finance Corp. completed a private offering of $500 million in aggregate principal amount of 7.000% senior notes due 2028. These notes will mature on September 15, 2028 and interest is payable semi-annually on March 15 and September 15 of each year. The Partnership used the proceeds from the private offering to repay a portion of the outstanding borrowings under our Credit Facility.

The 6.000% Senior Notes due 2027 will mature on April 15, 2027 and interest is payable semi-annually on April 15 and October 15 of each year. The 5.875% Senior Notes due 2028 will mature on March 15, 2028 and interest is payable semi-annually on March 15 and September 15 of each year. The 4.500% Senior Notes due 2029 will mature on May 15, 2029 and interest is payable semi-annually on May 15 and November 15 of each year. The 4.500% Senior Notes due 2030 will mature on April 30, 2030, and interest is payable semi-annually on April 30 and October 30 of each year.

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 April 7, 2022, we entered into a Second 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 April 7, 2027 (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 a base rate (a rate based off of the higher of (a) the Federal Funds Rate (as defined in the Credit Facility) 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 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 secured by a security interest in, among other things, all of the Partnership’s present and future personal property and all of the present and future personal property of its guarantors, the capital stock of its material subsidiaries, and any intercompany debt. Upon the first achievement by the Partnership of an investment grade credit rating, all security interests securing the Credit Facility will be released.

As of December 31, 2023, the balance on the Credit Facility was $411 million, and $5 million in standby letters of credit were outstanding. The unused availability on the Credit Facility at December 31, 2023 was $1.084 billion. The weighted average interest rate on the total amount outstanding at December 31, 2023 was 7.54%. The Partnership was in compliance with all financial covenants at December 31, 2023. The Partnership’s net leverage ratio was 3.66 to 1.00 at December 31, 2023.

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, 2023 and 2022, the balance of the sale leaseback financing obligation was $85 million.

Lease-related financing obligations also include finance lease obligations of $9 million as of December 31, 2023 and 2022, as further discussed in Note 13.

Fair Value of Debt

The aggregate estimated fair value and carrying amount of our consolidated debt obligations as of December 31, 2023 were $3.5 billion and $3.6 billion, respectively. As of December 31, 2022, the aggregate fair value and carrying amount of our consolidated debt obligations were $3.4 billion and $3.6 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.

Other non-current liabilities consisted of the following:

			December 31, 2023						December 31, 2022
Asset retirement obligations			$	84					$	81
Accrued environmental expense, long-term			12						12
Other			20						18
Other non-current liabilities			$	116					$	111

We record an asset retirement obligation for the estimated future cost to remove underground storage tanks. Revisions to the liability could occur due to changes in tank removal costs, tank useful lives or if federal and/or state regulators enact new guidance on

---

the removal of such tanks. Changes in the carrying amount of asset retirement obligations for the years ended December 31, 2023 and 2022 were as follows:

			Year Ended December 31,

We are party to fee-based commercial agreements with various affiliates of Energy Transfer for pipeline, terminalling and storage services. We also have agreements with subsidiaries of Energy Transfer for the purchase and sale of fuel.

Our investment in the J.C. Nolan joint ventures was $124 million and $129 million as of December 31, 2023 and 2022, respectively. In addition, we recorded income on the unconsolidated joint ventures of $5 million, $4 million and $4 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Significant affiliate balances included on our consolidated balance sheets were as follows:

•Accounts receivable from affiliates were $20 million and $15 million at December 31, 2023 and 2022, respectively, which were primarily related to motor fuel sales to affiliates.

•Accounts payable to affiliates were $170 million and $109 million as of December 31, 2023 and 2022, respectively, which were attributable to operational expenses and bulk fuel purchases.

•Advances from affiliates were $102 million and $116 million at December 31, 2023 and 2022, respectively, which were related to treasury services agreements with Energy Transfer.

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 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 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.

The following table depicts the disaggregation of revenue:

			Year Ended December 31,
			2023						2022						2021
Fuel			$	22,520					$	25,209					$	17,139
Non-fuel			284						277						260
Lease income			151						143						138

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. 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, 2023 and 2022 were as follows:

			December 31, 2023						December 31, 2022						Increase/ (Decrease)
Contract assets			$	256					$	200					$	56
Accounts receivable from contracts with customers			809						834						(25)
Contract liabilities			—						—						—

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. accounts for approximately 20% of both total revenues and motor fuel gallons sold.

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.

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, 2023, 2022 and 2021 was $29 million, $22 million and $21 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.

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 components of lease expense consisted of the following:

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.

Minimum future lease payments receivable as of December 31, 2023 were as follows:

2024						$	108

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 2023, our coverage was $10 million per occurrence and in the aggregate. Our sites continue to be covered by these policies.

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 components of the federal and state income tax expense (benefit) are summarized as follows:

			Year Ended December 31,

Total deferred tax expense			13						28						10
Income tax expense			$	36					$	26					$	30

Our effective tax rate differs from the statutory rate primarily due to Partnership earnings that are not subject to U.S. federal and most state income taxes at the Partnership level. A reconciliation of income tax expense at the U.S. federal statutory rate to net income tax expense is as follows:

			Year Ended December 31,

As of December 31, 2023, Sunoco Retail LLC, a corporate subsidiary of Sunoco LP, had a state net operating loss carryforward of $75 million, which we expect to fully utilize. Sunoco Retail LLC has no federal net operating loss carryforward.

As of December 31, 2023, 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 2023, 2022 or 2021.

We accrue interest and penalties on income tax underpayments (overpayments) as a component of income tax expense. During 2023, we recognized interest and penalties of $1 million. At December 31, 2023, we had interest and penalties accrued of $3 million, net of taxes.

The IRS is auditing a 2018 income tax refund claim filed by a wholly owned subsidiary of Sunoco LP. In general, the Partnership and its subsidiaries are no longer subject to examination by the Internal Revenue Service and most state jurisdictions for 2018 and prior years.

As of December 31, 2023, Energy Transfer and its subsidiaries owned 28,463,967 common units, which constitutes a 28.2% limited partner interest in the Partnership. As of December 31, 2023, our wholly owned consolidated subsidiaries owned 16,410,780 Class C units representing limited partner interests in the Partnership (the “Class C Units”) and the public owned 55,944,047 common units.

Common Units

Common unit activity for the years ended December 31, 2023 and 2022 was as follows:

			Number of Units
Number of common units at December 31, 2021			83,670,950
Phantom unit vesting			383,815
Number of common units at December 31, 2022			84,054,765
Phantom unit vesting			353,249
Number of common units at December 31, 2023			84,408,014

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:

			Year Ended December 31,
			2023						2022						2021
Attributable to Common Units
Distributions declared			$	284					$	277					$	275
Distributions (in excess of) less than net income			27						120						171
Common unitholders’ interest in net income			$	311					$	397					$	446

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.

									Marginal percentage interest in distributions
			Total quarterly distribution per Common unit target amount						Common Unitholders						Holder of IDRs
Minimum Quarterly Distribution			$0.4375						100		%				—
First Target Distribution			Above $0.4375 up to $0.503125						100		%				—
Second Target Distribution			Above $0.503125 up to $0.546875						85		%				15		%
Third Target Distribution			Above $0.546875 up to $0.656250						75		%				25		%
Thereafter			Above $0.656250						50		%				50		%

Cash Distributions

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

Cash distributions paid or to be paid were as follows: 

						Common Units
Payment Date						Per Unit Distribution						Total Cash Distribution						Distribution to IDR Holders
February 19, 2021						$	0.8255					$	69					$	18

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, $14 million and $16 million for the years ended December 31, 2023, 2022 and 2021, respectively. The total fair value of phantom units vested for the years ended December 31, 2023, 2022 and 2021, was $30 million, $22 million and $20 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 $33 million as of December 31, 2023, 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, 2023 and 2022, totaled $96 million and $79 million, respectively.

Phantom unit award activity for the years ended December 31, 2023 and 2022 consisted of the following:

			Number of Phantom Common Units						Weighted Average Grant Date Fair Value
Outstanding at December 31, 2021			2,014,288						$	30.92

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 our investments in the J.C. Nolan Terminal and the J.C. Nolan Pipeline.

Terminals. Our Terminals segment is composed of four transmix processing facilities and 42 refined product terminals.

Segment Operating Results

We report Adjusted EBITDA by segment as a measure of segment performance. We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation, amortization and accretion expense, non-cash compensation expense, gains and losses on disposal of assets 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.

The following tables present financial information by segment for the years ended December 31, 2023, 2022 and 2021.

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:

			Year Ended December 31,
			2023						2022						2021
Net Income and comprehensive income			$	394					$	475					$	524
Less:
Incentive distribution rights			77						72						71
Distributions on unvested phantom unit awards			6						6						7
Common unitholders’ interest in net income			$	311					$	397					$	446
Weighted average common units outstanding:
Basic			84,081,083						83,755,378						83,369,534
Dilutive effect of unvested phantom unit awards			1,012,414						1,048,320						1,068,742
Diluted			85,093,497						84,803,698						84,438,276

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, 2023, Energy Transfer and its subsidiaries owned 100% of the membership interests in our General Partner, all of our incentive distribution rights (“IDRs”) and approximately 33.7% of our common units, which constitutes a 28.2% limited partner interest in us. We distribute motor fuels across more than 40 states and territories throughout the United States, including Hawaii and Puerto Rico. We also operate retail stores in Hawaii and New Jersey. Our primary operations are conducted by the following consolidated subsidiaries: •Sunoco, LLC (“Sunoco LLC”), a Delaware limited liability company, primarily distributes motor fuel in more than 40 states throughout the United States. Sunoco LLC also processes transmix and distributes refined product through its terminals in over 15 states. •Sunoco Retail LLC (“Sunoco Retail”), a Pennsylvania limited liability company, owns and operates retail stores that sell motor fuel and merchandise primarily in New Jersey.

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2023
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 our investments in the J.C. Nolan Terminal and the J.C. Nolan Pipeline. Our Terminals segment is composed of four transmix processing facilities and 42 refined product terminals. 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 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. Inventories Fuel inventories are stated at the lower of cost or market using the last-in-first-out (“LIFO”) method. 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 $26 million, $25 million and $22 million for the years ended December 31, 2023, 2022 and 2021, 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, estimated to be forty years for buildings, three to fifteen years for equipment and thirty years for storage tanks. 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. 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 $13 million and $14 million as of December 31, 2023 and 2022, 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 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 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 operating leases 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 $274 million, $285 million and $332 million for the years ended December 31, 2023, 2022 and 2021, 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 twelve 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 First Amended and Restated Agreement of Limited Partnership, as amended (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. 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 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, 2023, 2022 and 2021, 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. These corporate subsidiaries include Sunoco Retail, Aloha and Peerless. 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.

Long-Term Debt	Long-Term Debt, net Total long-term debt, net consisted of the following: December 31, 2023 December 31, 2022 Credit Facility $ 411  $ 900  6.000% Senior Notes due 2027 600  600  5.875% Senior Notes due 2028 400  400  7.000% Senior Notes due 2028 500  —  4.500% Senior Notes due 2029 800  800  4.500% Senior Notes due 2030 800  800  Lease-related financing obligations 94  94  Total long-term debt 3,605  3,594  Less: debt issuance costs 25  23  Total long-term debt, net $ 3,580  $ 3,571  At December 31, 2023, scheduled future debt maturities were as follows: 2024 $ —  2025 —  2026 —  2027 1,011  2028 900  Thereafter 1,694  Total $ 3,605  Senior Notes The terms of each tranche of the Partnership’s senior notes (the “Senior Notes”) are governed by indentures among the Partnership and Sunoco Finance Corp. (together, the “Issuers”), and certain other subsidiaries of the Partnership (the “Guarantors”) and U.S. Bank National Association, as trustee. The 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 Senior Notes and guarantees are unsecured and rank equally with all of the Issuers’ and each Guarantor’s existing and future senior obligations. The 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 Senior Notes. On September 20, 2023, we and Sunoco Finance Corp. completed a private offering of $500 million in aggregate principal amount of 7.000% senior notes due 2028. These notes will mature on September 15, 2028 and interest is payable semi-annually on March 15 and September 15 of each year. The Partnership used the proceeds from the private offering to repay a portion of the outstanding borrowings under our Credit Facility. The 6.000% Senior Notes due 2027 will mature on April 15, 2027 and interest is payable semi-annually on April 15 and October 15 of each year. The 5.875% Senior Notes due 2028 will mature on March 15, 2028 and interest is payable semi-annually on March 15 and September 15 of each year. The 4.500% Senior Notes due 2029 will mature on May 15, 2029 and interest is payable semi-annually on May 15 and November 15 of each year. The 4.500% Senior Notes due 2030 will mature on April 30, 2030, and interest is payable semi-annually on April 30 and October 30 of each year. 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 April 7, 2022, we entered into a Second 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 April 7, 2027 (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 a base rate (a rate based off of the higher of (a) the Federal Funds Rate (as defined in the Credit Facility) 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 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 secured by a security interest in, among other things, all of the Partnership’s present and future personal property and all of the present and future personal property of its guarantors, the capital stock of its material subsidiaries, and any intercompany debt. Upon the first achievement by the Partnership of an investment grade credit rating, all security interests securing the Credit Facility will be released. As of December 31, 2023, the balance on the Credit Facility was $411 million, and $5 million in standby letters of credit were outstanding. The unused availability on the Credit Facility at December 31, 2023 was $1.084 billion. The weighted average interest rate on the total amount outstanding at December 31, 2023 was 7.54%. The Partnership was in compliance with all financial covenants at December 31, 2023. The Partnership’s net leverage ratio was 3.66 to 1.00 at December 31, 2023. 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, 2023 and 2022, the balance of the sale leaseback financing obligation was $85 million. Lease-related financing obligations also include finance lease obligations of $9 million as of December 31, 2023 and 2022, as further discussed in Note 13. Fair Value of Debt The aggregate estimated fair value and carrying amount of our consolidated debt obligations as of December 31, 2023 were $3.5 billion and $3.6 billion, respectively. As of December 31, 2022, the aggregate fair value and carrying amount of our consolidated debt obligations were $3.4 billion and $3.6 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	12 Months Ended
	Dec. 31, 2023
Revenue from Contract with Customer [Abstract]
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 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 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. The following table depicts the disaggregation of revenue: Year Ended December 31, 2023 2022 2021 Fuel $ 22,520  $ 25,209  $ 17,139  Non-fuel 284  277  260  Lease income 151  143  138  Terminal throughput 61  49  35  Other 52  51  24  Total revenues $ 23,068  $ 25,729  $ 17,596  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. 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, 2023 and 2022 were as follows:   December 31, 2023 December 31, 2022 Increase/ (Decrease) Contract assets $ 256  $ 200  $ 56  Accounts receivable from contracts with customers 809  834  (25) Contract liabilities —  —  —  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. accounts for approximately 20% of both total revenues and motor fuel gallons sold. 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. 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, 2023, 2022 and 2021 was $29 million, $22 million and $21 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. 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.

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies 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 components of lease expense consisted of the following: Year Ended December 31, Lease cost Classification 2023 2022 Operating lease costs: Operating lease cost Lease expense $ 51  $ 49  Finance lease costs: Amortization of leased assets Depreciation, amortization and accretion —  —  Interest on lease liabilities Interest expense —  —  Short-term lease cost Lease expense 2  2  Variable lease cost Lease expense 15  12  Sublease income Lease income (42) (39) Net lease cost $ 26  $ 24  Lease term and discount rate December 31, 2023 December 31, 2022 Weighted average remaining lease term (years) Operating leases 22 22 Finance leases 27 28 Weighted average discount rate (%) Operating leases 6% 6% Finance leases 4% 4% Year Ended December 31, Other information 2023 2022 Cash paid for amount included in the measurement of lease liabilities: Operating cash flows from operating leases $ (51) $ (49) Operating cash flows from finance leases —  —  Financing cash flows from finance leases —  —  Leased assets obtained in exchange for new finance lease liabilities —  —  Leased assets obtained in exchange for new operating lease liabilities —  17  Maturities of lease liabilities as of December 31, 2023 were as follows: Maturity of lease liabilities Operating leases Finance leases Total 2024 $ 50  $ —  $ 50  2025 48  —  48  2026 47  —  47  2027 46  —  46  2028 45  —  45  Thereafter 726  15  741  Total lease payments 962  15  977  Less: interest 429  6  435  Present value of lease liabilities $ 533  $ 9  $ 542  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. Minimum future lease payments receivable as of December 31, 2023 were as follows: 2024 $ 108  2025 99  2026 82  2027 63  2028 38  Thereafter 17  Total undiscounted cash flows $ 407  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 2023, our coverage was $10 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 $18 million as of December 31, 2023 and 2022, which are classified as accrued expenses and other current liabilities and other non-current liabilities.

Income Tax Disclosure [Abstract]
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 components of the federal and state income tax expense (benefit) are summarized as follows: Year Ended December 31, 2023 2022 2021 Current: Federal $ 16  $ —  $ 15  State 7  (2) 5  Total current income tax expense (benefit) 23  (2) 20  Deferred:   Federal 9  24  7  State 4  4  3  Total deferred tax expense 13  28  10  Income tax expense $ 36  $ 26  $ 30  Our effective tax rate differs from the statutory rate primarily due to Partnership earnings that are not subject to U.S. federal and most state income taxes at the Partnership level. A reconciliation of income tax expense at the U.S. federal statutory rate to net income tax expense is as follows: Year Ended December 31, 2023 2022 2021 (in millions) Income tax expense at United States statutory rate $ 90  $ 105  $ 116  Increase (reduction) in income taxes resulting from: Partnership earnings not subject to tax (64) (74) (96) State and local tax, including federal expense 10  1  7  Other —  (6) 3  Income tax expense $ 36  $ 26  $ 30  Deferred taxes result from the temporary differences between financial reporting carrying amounts and the tax basis of existing assets and liabilities. Principal components of deferred tax assets and liabilities were as follows: December 31, 2023 December 31, 2022 Deferred tax assets:     Net operating and other loss carry forwards $ 3  $ 3  Other 21  22  Total deferred tax assets 24  25  Deferred tax liabilities: Property and equipment 55  52  Trademarks and other intangibles 91  89  Investments in unconsolidated affiliates 44  39  Other —  1  Total deferred tax liabilities 190  181  Net deferred income tax liabilities $ 166  $ 156  As of December 31, 2023, Sunoco Retail LLC, a corporate subsidiary of Sunoco LP, had a state net operating loss carryforward of $75 million, which we expect to fully utilize. Sunoco Retail LLC has no federal net operating loss carryforward. As of December 31, 2023, 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 2023, 2022 or 2021. We accrue interest and penalties on income tax underpayments (overpayments) as a component of income tax expense. During 2023, we recognized interest and penalties of $1 million. At December 31, 2023, we had interest and penalties accrued of $3 million, net of taxes. The IRS is auditing a 2018 income tax refund claim filed by a wholly owned subsidiary of Sunoco LP. In general, the Partnership and its subsidiaries are no longer subject to examination by the Internal Revenue Service and most state jurisdictions for 2018 and prior years.

As of December 31, 2023, our wholly owned consolidated subsidiaries owned 16,410,780 Class C units representing limited partner interests in the Partnership (the “Class C Units”) and the public owned 55,944,047 common units. Common Units Common unit activity for the years ended December 31, 2023 and 2022 was as follows: Number of Units Number of common units at December 31, 2021 83,670,950  Phantom unit vesting 383,815  Number of common units at December 31, 2022 84,054,765  Phantom unit vesting 353,249  Number of common units at December 31, 2023 84,408,014  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: Year Ended December 31,   2023 2022 2021 Attributable to Common Units       Distributions declared $ 284  $ 277  $ 275  Distributions (in excess of) less than net income 27  120  171  Common unitholders’ interest in net income $ 311  $ 397  $ 446  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.     Marginal percentage interest in distributions   Total quarterly distribution per Common unit target amount Common Unitholders Holder of IDRs Minimum Quarterly Distribution $0.4375 100  % —  First Target Distribution Above $0.4375 up to $0.503125 100  % —  Second Target Distribution Above $0.503125 up to $0.546875 85  % 15  % Third Target Distribution Above $0.546875 up to $0.656250 75  % 25  % Thereafter Above $0.656250 50  % 50  % Cash Distributions Our Partnership Agreement sets forth the calculation used to determine the amount and priority of cash distributions that the common unitholders receive. Cash distributions paid or to be paid were as follows:    Common Units   Payment Date Per Unit Distribution Total Cash Distribution Distribution to IDR Holders February 19, 2021 $ 0.8255  $ 69  $ 18  May 19, 2021 0.8255  69  18  August 19, 2021 0.8255  69  18  November 19, 2021 0.8255  69  18  February 18, 2022 0.8255  69  18  May 19, 2022 0.8255  69  18  August 19, 2022 0.8255  69  18  November 18, 2022 0.8255  69  18  February 21, 2023 0.8255  69  18  May 22, 2023 0.8420  71  19  August 21, 2023 0.8420  71  19  November 20, 2023 0.8420  71  19  February 20, 2024 0.8420  71  19

Unit-Based Compensation	12 Months Ended
	Dec. 31, 2023
Share-Based Payment Arrangement [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, $14 million and $16 million for the years ended December 31, 2023, 2022 and 2021, respectively. The total fair value of phantom units vested for the years ended December 31, 2023, 2022 and 2021, was $30 million, $22 million and $20 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 $33 million as of December 31, 2023, 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, 2023 and 2022, totaled $96 million and $79 million, respectively. Phantom unit award activity for the years ended December 31, 2023 and 2022 consisted of the following:   Number of Phantom Common Units Weighted Average Grant Date Fair Value Outstanding at December 31, 2021 2,014,288  $ 30.92  Granted 441,049  43.54  Vested (525,608) 29.95  Forfeited (107,956) 30.31  Outstanding at December 31, 2022 1,821,773  34.29  Granted 399,377  53.37  Vested (552,145) 28.35  Forfeited (68,640) 34.64  Outstanding at December 31, 2023 1,600,365  $ 41.08

Segment Reporting [Abstract]
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 our investments in the J.C. Nolan Terminal and the J.C. Nolan Pipeline. Terminals. Our Terminals segment is composed of four transmix processing facilities and 42 refined product terminals. Segment Operating Results We report Adjusted EBITDA by segment as a measure of segment performance. We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation, amortization and accretion expense, non-cash compensation expense, gains and losses on disposal of assets 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. The following tables present financial information by segment for the years ended December 31, 2023, 2022 and 2021.

Net Income per Unit	12 Months Ended
	Dec. 31, 2023
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: Year Ended December 31,   2023 2022 2021 Net Income and comprehensive income $ 394  $ 475  $ 524  Less: Incentive distribution rights 77  72  71  Distributions on unvested phantom unit awards 6  6  7  Common unitholders’ interest in net income $ 311  $ 397  $ 446  Weighted average common units outstanding:       Basic 84,081,083  83,755,378  83,369,534  Dilutive effect of unvested phantom unit awards 1,012,414  1,048,320  1,068,742  Diluted 85,093,497  84,803,698  84,438,276  Net income per common unit:       Basic $ 3.70  $ 4.74  $ 5.35  Diluted $ 3.65  $ 4.68  $ 5.28

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
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 our investments in the J.C. Nolan Terminal and the J.C. Nolan Pipeline. Our Terminals segment is composed of four transmix processing facilities and 42 refined product terminals.
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 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.
Inventories	Inventories Fuel inventories are stated at the lower of cost or market using the last-in-first-out (“LIFO”) method. 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 $26 million, $25 million and $22 million for the years ended December 31, 2023, 2022 and 2021, 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, estimated to be forty years for buildings, three to fifteen years for equipment and thirty years for storage tanks. 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 $13 million and $14 million as of December 31, 2023 and 2022, 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 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 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 operating leases is recognized on a straight-line basis over the term of the lease.
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 $274 million, $285 million and $332 million for the years ended December 31, 2023, 2022 and 2021, 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 twelve 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	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 First Amended and Restated Agreement of Limited Partnership, as amended (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, 2023, 2022 and 2021, 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. These corporate subsidiaries include Sunoco Retail, Aloha and Peerless. 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
