 Item 1. Business
 General
 As used in this report, the terms "Partnership," "SUN," "we," "us" or "our" should be understood to refer to Sunoco LP and our consolidated subsidiaries as applicable and appropriate.
 Overview
 We are a Delaware master limited partnership. We are managed by our general partner, Sunoco GP LLC (our "General Partner"), which is owned by Energy Transfer LP ("Energy Transfer"). As of February 9, 2024, Energy Transfer owned 100% of the membership interests in our General Partner, 28,463,967 of our common units, which constituted a 28.2% limited partner interest in us, and all of our incentive distribution rights ("IDRs").

 The following simplified diagram depicts our organizational structure as of February 9, 2024.

 We are primarily engaged in the distribution of motor fuels to independent dealers, distributors and other commercial customers as well as the distribution of motor fuels to end-use customers at retail sites operated by commission agents. Additionally, we receive lease income through the leasing or subleasing of real estate used in the retail distribution of motor fuels. As of December 31, 2023, we also operated 75 retail stores located in Hawaii and New Jersey.
 As of December 31, 2023, we distribute motor fuels across more than 40 states and territories throughout the United States, including Hawaii and Puerto Rico. We distributed approximately 8.3 billion gallons of motor fuel during 2023 through our independent dealers, distributors, other commercial customers, retail sites operated by commission agents and retail sites owned and operated by us.
 Operating Subsidiaries
 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.
 Recent Developments
 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.
 On September 20, 2023, the Partnership completed a private offering of $500 million in aggregate principal amount of 7.000% senior notes due 2028. We used the proceeds to repay a portion of the outstanding borrowings under our Credit Facility (as defined herein).
 On May 1, 2023, the Partnership completed the acquisition of 16 refined product terminals located across the East Coast and Midwest from Zenith Energy for $111 million, including working capital. The purchase price was primarily allocated to property and equipment.
 Available Information
 Our principal executive offices are located at 8111 Westchester Drive, Suite 400, Dallas, Texas 75225. Our telephone number is (214) 981-0700. Our Internet address is www.sunocolp.com. We make available through our website our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after we electronically file such material with, or furnish such material to, the Securities and Exchange Commission (the "SEC"). Information contained on our website is not part of this report. The SEC maintains an Internet site at www.sec.gov that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC.
 Our Relationship with Energy Transfer LP
 One of our principal strengths is our relationship with Energy Transfer. As of February 9, 2024, Energy Transfer owned 100% of the membership interest in our General Partner, all of our IDRs and 28,463,967 of our common units, which constituted a 28.2% limited partner interest in us. Given the significant ownership, we believe Energy Transfer will be motivated to promote and support the successful execution of our business strategies. In particular, we believe it will be in the best interest of Energy Transfer to facilitate organic growth opportunities and accretive acquisitions of third parties, although Energy Transfer is not under any obligation to do so.
 Energy Transfer is one of the largest and most diversified midstream energy companies in North America. Energy Transfer, through its wholly owned operating subsidiaries, is primarily engaged in:
 • natural gas midstream, intrastate and interstate transportation and storage operations; and
 • crude oil, natural gas liquids ("NGL") and refined products transportation, terminalling and acquisition and marketing activities as well as NGL storage and fractionation services.

 Our Business and Operations
 Our business is comprised of two reportable segments: Fuel Distribution and Marketing and All Other.
 The map below depicts the major assets of our business and excludes corporate and field offices and certain assets that are less significant to SUN.

 Fuel Distribution and Marketing Segment
 We are a distributor of motor fuels and other petroleum products which we supply to third-party dealers and distributors, to independent operators of commission agent locations, other commercial consumers of motor fuel and to our retail locations. Also included in the segment are transmix processing plants and refined products terminals. Transmix is the mixture of various refined products (primarily gasoline and diesel) created in the supply chain (primarily in pipelines and terminals) when various products interface with each other. Transmix processing plants separate this mixture and return it to salable products of gasoline and diesel.
 We are the exclusive wholesale supplier of the Sunoco and EcoMaxx-branded motor fuels, supplying an extensive distribution network of approximately 5,534 company and third-party operated locations throughout the United States and Puerto Rico. We believe we are one of the largest independent motor fuel distributors, by gallons, in the United States. We also are one of the largest distributors of Chevron, Texaco, ExxonMobil and Valero branded motor fuel in the United States. In addition to distributing motor fuels, we also distribute other petroleum products such as propane and lubricating oil, and we receive lease income from real estate that we lease or sublease.
 We purchase motor fuel primarily from independent refiners and major oil companies and distribute it across more than 40 U.S. states and territories throughout the United States, including Hawaii and Puerto Rico, to:
 •75 company-operated retail stores;
 •476 independently operated commission agent locations where we sell motor fuel to retail customers under commission agent arrangements with such operators;
 •6,828 retail stores operated by independent operators, which we refer to as "dealers" or "distributors," pursuant to long-term distribution agreements; and
 • approximately 1,600 other commercial customers, including unbranded retail stores, other fuel distributors, school districts, municipalities and other industrial customers.
 Dealer Incentives
 In addition to motor fuel distribution, we offer dealers the opportunity to participate in merchandise purchasing and promotional programs arranged with vendors. We believe the vendor relationships we have established through our retail operations and our ability to develop programs provide us with an advantage over other distributors when recruiting new dealers into our network as well as with retaining current dealers. Our dealer incentives give our dealers access to discounted rates on products and services that they would likely not be able to obtain on their own.

 Sales to Contracted Third Parties
 We distribute fuel under long-term contracts to branded distributors, branded and unbranded convenience stores, and branded and unbranded retail fuel outlets operated by third parties. 7-Eleven, Inc. is the only third-party dealer or distributor which is individually over 10% of our Fuel Distribution and Marketing segment or individually over 10%, in terms of revenue, of our aggregate business.
 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.
 Distribution contracts with retail stores generally commit us to distribute branded (including, but not limited to, Sunoco branded) or unbranded motor fuel to a location or group of locations and arrange for all transportation and logistics. These contracts require, among other things, that dealers maintain the standards established by the applicable fuel brand, if any. The initial term of these contracts range from three to 20 years, with most contracts for 10 years.
 Our supply contracts and distribution contracts are typically constructed so that we receive either (i) a fee per gallon equal to the posted rack rate, less any applicable commercial discounts, plus transportation costs, taxes and a fixed, volume-based fee, which is usually expressed in cents per gallon, or (ii) a variable cent per gallon margin ("dealer tank wagon pricing").
 During 2023, our Fuel Distribution and Marketing business distributed fuel to 476 commission agent locations. Under these arrangements, we generally provide and control motor fuel inventory and price at the site and receive actual retail selling price for each gallon sold, less a commission paid to the independent commission agents.
 We continually seek to expand through the addition of new branded dealers, distributors and commission agent locations, new unbranded commercial customers and through acquisitions of contracts for existing independently operated sites from other distributors. We evaluate potential independent site operators based on their creditworthiness and the quality of their sites and operations, including the site's size and location, projected monthly volumes of motor fuel, monthly merchandise sales, overall financial performance and previous operating experience. We may extend credit to certain dealers based on our credit evaluation process.
 Sales to Other Commercial Customers
 We distribute unbranded fuel to numerous other customers, including retail stores, unattended fueling facilities and certain other commercial customers. These customers are primarily commercial, governmental and other parties who buy motor fuel by the load or in bulk and who do not generally enter into exclusive contractual relationships with us, if they enter into a contractual relationship with us at all. Sales to these customers are typically made at a quoted price based upon our cost plus taxes, cost of transportation and a margin determined at time of sale, and may provide for immediate payment or the extension of credit for up to 45 days. We also sell propane, lubricating oil and other petroleum products, such as heating fuels, to our commercial customers on both a spot and contracted basis. In addition, we receive income from the manufacture and distribution sale of race fuels at our Marcus Hook, Pennsylvania manufacturing facility.
 Fuel Supplier Arrangements
 We distribute branded motor fuel under the Aloha, Chevron, Citgo, Conoco, EcoMaxx, Exxon, Mahalo, Mobil, Phillips 66, Shamrock, Shell, Sunoco, Texaco and Valero brands. We purchase branded motor fuel from major oil companies and refiners under supply agreements. Our largest branded fuel suppliers in terms of volume are Chevron, Exxon, Phillips 66 and Valero. The branded fuel supply agreements generally have an initial term of three to five years. Each supply agreement typically contains provisions relating to payment terms, use of the supplier's brand names, credit card processing, compliance with other of the supplier's requirements, insurance coverage and compliance with legal and environmental requirements, among others.
 We also distribute unbranded motor fuel, which we purchase in bulk, on a rack basis based upon prices posted by the refiner at a fuel supply terminal or on a contract basis with the price tied to one or more market indices.
 Bulk Fuel Purchases
 We purchase motor fuel in bulk and hold it in inventory or transport it via pipeline. To mitigate inventory risk, we use commodity futures contracts or other derivative instruments, which are matched in quantity and timing to the anticipated usage of the inventory. We also blend in various additives, including ethanol and biomass-based diesel.
 Terminals and Transmix
 We operate four transmix processing facilities and 42 refined product terminals (one in Puerto Rico, six in Hawaii and 35 in the continental United States). Transmix is the mixture of various refined products (primarily gasoline and diesel) created in the supply chain (primarily in pipelines and terminals) when various products interface with each other. Transmix processing plants separate this mixture and return it to salable products of gasoline and diesel. Our refined product terminals provide storage and distribution services

 used to supply our own retail stations as well as third-party customers. In addition, we provide services at our terminals to various third-party throughput customers.
 Transportation Logistics
 We provide transportation logistics for most of our motor fuel deliveries through our own fleet of fuel transportation vehicles as well as third-party and affiliated transportation providers. We arrange for motor fuel to be delivered from the storage terminals to the appropriate sites in our distribution network at prices consistent with those historically charged to third parties for the delivery of fuel. We also deliver motor fuel, propane and lubricating oils to commercial customers involved in petroleum exploration and production.
 J.C. Nolan Joint Venture
 Through our investment in the J.C. Nolan Terminal, a joint venture with Energy Transfer, we provide diesel fuel storage in Midland, Texas. Additionally, through our investment in J.C. Nolan Pipeline, we transport diesel fuel from a tank farm in Hebert, Texas to Midland, Texas, with a throughput capacity of approximately 36 MBbls/d.
 Technology
 Technology is an important part of our Fuel Distribution and Marketing operations. We utilize a proprietary web-based system that allows our wholesale customers to access their accounts at any time from a personal computer to obtain prices, place orders and review invoices, credit card transactions and electronic funds transfer notifications. Substantially all of our customer payments are processed by electronic funds transfer. We use an Internet-based system to assist with fuel inventory management and procurement and an integrated distribution fuel system for financial accounting, procurement, billing and inventory management.
 All Other Segment
 Our All Other segment includes the Partnership's retail operations in Hawaii and New Jersey, credit card services and franchise royalties.
 For further detail of our segment results refer to "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 19 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data."
 Sale of Regulated Products
 In certain areas where our convenience stores are located, state or local laws limit the hours of operation for the sale of alcoholic beverages and restrict the sale of alcoholic beverages and tobacco products to persons younger than a certain age. State and local regulatory agencies have the authority to approve, revoke, suspend or deny applications for and renewals of permits and licenses relating to the sale of alcoholic beverages, as well as to issue fines to convenience stores for the improper sale of alcoholic beverages and tobacco products. Failure to comply with these laws may result in the loss of necessary licenses and the imposition of fines and penalties on us.
 Real Estate and Lease Arrangements
 As of December 31, 2023, our real estate and lease arrangements were as follows:

 Owned
 Leased

 Dealer and commission agent sites

 Company-operated retail stores

 Warehouses, offices and other

 Total

 Competition
 In the Fuel Distribution and Marketing segment, we compete primarily with other independent motor fuel distributors. The markets for distribution of motor fuel and the retail store industry are highly competitive and fragmented, which results in narrow margins. We have numerous competitors, some of which may have significantly greater resources and name recognition than we do. Significant competitive factors include the availability of major brands, customer service, price, range of services offered and quality of service, among others. We rely on our ability to provide value-added, reliable service and control our operating costs in order to maintain our margins and competitive position.
 In the All Other segment, we face strong competition in the market for the sale of retail gasoline and merchandise. Our competitors include service stations of large integrated oil companies, independent gasoline service stations, convenience stores, fast food stores, supermarkets, drugstores, dollar stores, club stores and other similar retail outlets, some of which are well-recognized national or regional retail systems. The number of competitors varies depending on the geographical area. Competition also varies

 with gasoline and convenience store offerings. The principal competitive factors affecting our retail marketing operations include gasoline and diesel acquisition costs, site location, product price, selection and quality, site appearance and cleanliness, hours of operation, store safety, customer loyalty and brand recognition. We compete by pricing gasoline competitively, combining our retail gasoline business with convenience stores that provide a wide variety of products, and using advertising and promotional campaigns.
 Seasonality
 Our business exhibits some seasonality due to our customers' increased demand for motor fuel during the late spring and summer months, as compared to the fall and winter months. Travel, recreation and construction activities typically increase in these months in the geographic areas in which we operate, increasing the demand for motor fuel. Therefore, the volume of motor fuel that we distribute is typically somewhat higher in the second and third quarters of our fiscal year. As a result, our results from operations may vary from period to period.
 Working Capital Requirements
 Related to our retail store operations, we maintain customary levels of fuel and merchandise inventories and carry corresponding payable balances to suppliers of those inventories. In addition, Sunoco LLC purchases and stores a significant amount of unbranded fuel in bulk. We also have rental obligations related to leased locations. Our working capital needs will typically fluctuate over the medium to long term with the price of crude oil, and over the short term due to the timing of motor fuel tax, sales tax, interest and rent payments.
 Environmental Matters
 Environmental Laws and Regulations
 We are subject to various federal, state and local environmental laws and regulations, including those relating to underground storage tanks; the release or discharge of hazardous materials into the air, water and soil; the generation, storage, handling, use, transportation and disposal of regulated materials; the exposure of persons to regulated materials; and the remediation of contaminated soil and groundwater. For more information, see "Our operations are subject to federal, state and local laws and regulations pertaining to environmental protection and operational safety that may require significant expenditures or result in liabilities that could have a material adverse effect on our business" in "Item 1A. Risk Factors" in this Annual Report on Form 10-K.
 Environmental laws and regulations can restrict or impact our business activities in many ways, such as:
 • requiring remedial action to mitigate releases of hydrocarbons, hazardous substances or wastes caused by our operations or attributable to former operators;
 • requiring capital expenditures to comply with environmental control requirements; and
 • enjoining the operations of facilities deemed to be in noncompliance with environmental laws and regulations.
 Failure to comply with environmental laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of monetary penalties, the imposition of remedial requirements and the issuance of orders enjoining or otherwise curtailing future operations. Certain environmental statutes impose strict, joint and several liability for costs required to clean up and restore sites where hydrocarbons, hazardous substances or wastes have been released or disposed of. Moreover, neighboring landowners and other third parties may file claims for personal injury and property damage allegedly caused by the release of hydrocarbons, hazardous substances or other wastes into the environment.
 We believe we are in compliance in all material respects with applicable environmental laws and regulations, and we do not believe that compliance with federal, state or local environmental laws and regulations will have a material adverse effect on our financial position, results of operations or cash available for distribution to our unitholders. Any future change in regulatory requirements could cause us to incur significant costs. We incorporate by reference into this section our disclosures included in Note 13 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data."
 Hazardous Substances and Releases
 Certain environmental laws, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), impose strict, and under certain circumstances, joint and several, liability on the owner and operator as well as former owners and operators of properties for the costs of investigation, removal or remediation of contamination and also impose liability for any related damages to natural resources without regard to fault. In addition, under CERCLA and similar state laws, as persons who arrange for the transportation, treatment or disposal of hazardous substances, we also may be subject to similar liability at sites where such hazardous substances come to be located. We may also be subject to third-party claims alleging property damage and/or personal injury in connection with releases of or exposure to hazardous substances at, from or in the vicinity of, our current properties or off-site waste disposal sites.

 We are required to comply with federal and state financial responsibility requirements to demonstrate that we have the ability to pay for remediation or to compensate third parties for damages incurred as a result of a release of regulated materials from our underground storage tank systems. We meet these requirements primarily by maintaining insurance, which we purchase from private insurers.
 Environmental Reserves
 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. As of December 31, 2023, we have additional reserves of $84 million that represent our estimate for future asset retirement obligations for underground storage tanks.
 Underground Storage Tanks
 We are required to make financial expenditures to comply with regulations governing underground storage tanks adopted by federal, state and local regulatory agencies. Pursuant to the Resource Conservation and Recovery Act of 1976, as amended, the Environmental Protection Agency ("EPA") has established a comprehensive regulatory program for the detection, prevention, investigation and cleanup of leaking underground storage tanks. State or local agencies are often delegated the responsibility for implementing the federal program or developing and implementing equivalent state or local regulations. We have a comprehensive program in place for performing routine tank testing and other compliance activities, which are intended to promptly detect and investigate any potential releases. We believe we are in compliance in all material respects with requirements applicable to our underground storage tanks.
 Air Emissions and Climate Change
 The Clean Air Act and similar state laws impose requirements on emissions to the air from motor fueling activities in certain areas of the country, including those that do not meet state or national ambient air quality standards. These laws and implementing regulations may require the installation of vapor recovery systems to control emissions of volatile organic compounds to the air during the motor fueling process or otherwise in the course of our operations. For example, in October 2023, the EPA proposed changes to its new source performance standards for new, modified and reconstructed storage vessels containing volatile organic liquids, a term which includes certain of our products. The EPA's proposal would broaden the definition of modification for storage tanks (which would result in significantly broader application of this rule to existing tanks), introduce more stringent emission control requirements for certain tanks, impose additional annual monitoring requirements for certain tanks, and require control of degassing events, amongst other matters. Costs to comply with new rules under the Clean Air Act can be substantial. In addition, under the Clean Air Act and comparable state and local laws, permits are typically required to emit regulated air pollutants into the atmosphere. We believe that we currently hold, or have applied for, all necessary air permits and that we would be in compliance in all material respects with applicable air laws and regulations. Although we can give no assurances, we are aware of no changes to air quality regulations that will have a material adverse effect on our financial condition, results of operations or cash available for distribution to our unitholders.
 Various federal, state and local agencies have the authority to prescribe product quality specifications for the motor fuels that we sell, largely in an effort to reduce air pollution. Failure to comply with these regulations can result in substantial penalties. Although we can give no assurances, we believe we are currently in compliance in all material respects with these regulations.
 Efforts at the federal and state level are currently underway to reduce the levels of greenhouse gas ("GHG") emissions from various sources in the United States. At the federal level, Congress has considered legislation to reduce GHG emissions in the United States. Such federal legislation may impose a carbon emissions tax or establish a cap-and-trade program or regulation by the EPA. For example, in 2022 President Biden signed the IRA 2022 into law, which appropriated significant federal funding for renewable energy initiatives and imposed the first-ever federal fee on methane emissions from certain oil and gas facilities. Even in the absence of new federal legislation, GHG emissions have begun to be regulated by the EPA pursuant to the Clean Air Act. For example, in April 2010, the EPA set a new emissions standard for motor vehicles to reduce GHG emissions. This vehicle emission standard has become increasingly stringent overtime; for example, in December 2021, the Biden Administration announced revised GHG emissions standards for light-duty vehicle fleets for Model Years 2023-2026 that require lower average emissions per mile. Several states have also adopted, or are considering adopting, regulations related to GHG emissions, some of which are more stringent than those implemented by the federal government. New federal or state restrictions on emissions of GHGs that may be imposed in areas of the United States in which we conduct business and that apply to our operations could adversely affect the demand for our products.
 In addition, the federal regulation of methane emissions from the oil and gas sector have been subject to substantial uncertainty in recent years. In 2020, the Trump Administration revised regulations initially promulgated in June 2016 to rescind certain methane standards and remove the transmission and storage segments from the source category for certain regulations. However, subsequently, the U.S. Congress approved, and President Biden signed into law, a resolution under the Congressional Review Act to repeal the September 2020 revisions to the methane standards, effectively reinstating the prior standards. Separately, in December 2023, the EPA finalized more stringent methane emission standards for certain sources in the oil and gas sector, including first-ever standards for

 existing sources. Under the final rules, states have two years to prepare and submit their plans to impose methane emission controls on existing sources. The presumptive standards under the final rule are generally the same for both new and existing sources, including enhanced leak detection survey requirements using optical gas imaging and other advanced monitoring to encourage the deployment of innovative technologies to detect and reduce methane emissions, reduction of emissions by 95% through capture and control systems, zero-emission requirements for certain devices, and the establishment of a "super emitter" response program that would allow third parties to make reports to the EPA of large methane emissions events, triggering certain investigation and repair requirements. It is likely, however, that the final rule and its requirements will be subject to legal challenges. Additionally, President Biden has announced that climate change will be a focus of his administration. In January 2021, he issued an executive order calling for substantial action on climate change, including, among other things, the increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry, and increased emphasis on climate-related risks across agencies and economic sectors. Subsequently, various federal agencies have taken, or have announced plans to take, further actions relating to climate change, some of which may impact our operations.
 At the international level, the United States and 195 other countries reached an agreement (the "Paris Agreement") during the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change, a long-term, international framework convention designed to address climate change over the next several decades. President Biden has recommitted the United States to the Paris agreement and, in April 2021, announced a goal of reducing the United States' emissions by 50-52% below 2005 levels by 2030. Additionally, at the 2021 United Nations Climate Change Conference ("COP26") in Glasgow in November 2021, the United States and the European Union jointly announced the launch of a Global Methane Pledge, an initiative committing to a collective goal of reducing global methane emissions by at least 30% from 2020 levels by 2030, including "all feasible reductions" in the energy sector. These goals were reaffirmed at the 2022 United Nations Climate Change Conference ("COP27"), and countries were called upon to accelerate the phase-out of inefficient fossil fuel subsidies, though no firm commitments or timelines were made. At the 2023 United Nations Climate Change Conference ("COP28") in December 2023, the parties signed onto an agreement to transition away from fossil fuels in energy systems and increase renewable energy capacity, though no timeline for doing so was set. While non-binding, the agreements coming out of COP28 could result in increased pressure among financial institutions and various stakeholders to reduce or otherwise impose more stringent limitations on funding for and increase potential opposition to the production and use of fossil fuels. The full impact of these actions is uncertain at this time. However, any efforts to control and/or reduce GHG emissions by the United States or other countries, or concerted conservation efforts that result in reduced consumption, could adversely impact demand for our products and, in turn, our financial position and results of operations.
 Climate change may also result in various physical risks, such as the increased frequency or intensity of extreme weather events or changes in meteorological and hydrological patterns that could adversely impact our operations or those of our supply chains. Such physical risks may result in damage to our facilities or our customers' facilities or otherwise adversely impact our operations, such as to the extent changing weather and temperature trends reduce the demand for our products or frequency with which consumers may visit our locations or impact the cost or availability of insurance. Moreover, certain parties, including local and state governments, have from time to time filed lawsuits against various fossil fuel energy companies seeking damages for alleged physical impacts resulting from climate change or relating to false or misleading statements related to fossil fuel's contribution to climate change. Further, there are increasing financial risks to companies in the fossil fuel sector as members of the general financial and investment communities increase sustainability considerations in their practices. For example, at COP26, the Glasgow Financial Alliance for Net Zero ("GFANZ") announced that commitments from over 450 firms across 45 countries had resulted in over $130 trillion in capital committed to net zero goals. The various sub-alliances of GFANZ generally require participants to set short-term, sector-specific targets to transition their financing, investing, and/or underwriting activities to net zero emissions by 2050. There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. The Federal Reserve has joined the Network for Greening the Financial System ("NGFS"), a consortium of financial regulators focused on addressing climate-related risks in the financial sector, and, in November 2021, the Federal Reserve issued a statement in support of the efforts of the NGFS to identify key issues and potential solutions for the climate-related challenges most relevant to central banks and supervisory authorities. In January 2023, the Federal Reserve issued instructions for a pilot climate analysis scenario being undertaken by six of the United States' largest banks, which concluded in 2023. These efforts may adversely affect the market for our securities and our ability to access capital and financial markets in the future.
 Additionally, the SEC has published a proposed rule that would require climate-related disclosures from registrants, including information on climate-related business strategy and disclosures related to GHG emissions. Although the final form and substance of these requirements is not yet known, this may result in additional costs to comply with any such disclosure requirements. Additionally, we cannot predict how financial institutions or investors might consider any information included these disclosures when making investment decisions, and as a result it is possible we could face increased costs related to, or restrictions imposed on, our access to capital. Similarly, in October 2023 the Governor of California signed the Climate Corporate Data Accountability Act ("CCDAA") and Climate-Related Financial Risk Act ("CRFRA") into law. The CCDAA requires both public and private U.S. companies that are "doing business in California" and that have a total annual revenue of $1 billion to publicly disclose and verify, on an annual basis, Scope 1, 2, and 3 GHG emissions. Both laws are vague and potentially overbroad with respect to their applicability, appearing to require only minimal contacts with California. The CRFRA requires the disclosure of a climate-related financial risk report in line

 with certain stakeholder frameworks every other year for public and private companies that are "doing business in California" and have total annual revenue of $500 million. Reporting under both laws would begin in 2026. Currently, the ultimate impact of these laws on our business is uncertain—the Governor of California has directed further consideration of the implementation deadlines for each of the laws, and there is potential for legal challenges to be filed with respect to the scope of the laws—but, absent clarification or revisions to the laws, alongside the SEC proposed rule, finalization and implementation may result in additional costs to comply with these disclosure requirements as well as increased costs of and restrictions on access to capital. Separately, enhanced climate related disclosure requirements could lead to reputational or other harm with customers, regulators, investors or other stakeholders and could also increase our litigation risks relating to alleged climate-related damages resulting from our operations, statements alleged to have been made by us or others in our industry regarding climate change risks, or in connection with any future disclosures we may make regarding reported emissions, particularly given the inherent uncertainties and estimations with respect to calculating and reporting GHG emissions. These various political, regulatory, financial, physical and litigation risks related to climate change have the potential adversely impact our operations and financial performance.
 Water
 The U.S. Federal Water Pollution Control Act, as amended, (the "Clean Water Act"), and analogous state laws, impose restrictions and strict controls regarding the discharge of pollutants into navigable waters of the United States ("WOTUS"). The definition of WOTUS has been subject to repeated change in recent years. Most recently, following legal action on a January 2023 final rule, the U.S. Supreme Court's decision in Sackett v. EPA, and the enactment of a subsequent September 2023 rule, the implementation of the definition is split based on jurisdiction. In 27 states, the January 2023 rule is enjoined subject to litigation, and the EPA and the U.S. Army Corps of Engineers are implementing the definition of WOTUS consistent with the pre-2015 regulatory regime and the changes made by the Sackett decision, which utilizes the "continuous surface connection" test to determine if wetlands qualify as WOTUS. In the remaining 23 states, the agencies are implementing the September 2023 rule, which amended the January 2023 rule to incorporate the Sackett decision. However, the September 2023 rule does not define the term "continuous surface connection," and it is currently unclear how broadly the September 2023 rule and the Sackett decision will be interpreted by the agencies. To the extent any action further expands the scope of the Clean Water Act's jurisdiction, it could cause increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas. Federal and state regulatory agencies can impose administrative, civil and/or criminal penalties for non-compliance with discharge permits or other requirements of the Clean Water Act, and can also pursue injunctive relief to enforce compliance with the Clean Water Act and analogous laws. Spill prevention control and countermeasure requirements of federal and state laws require containment to mitigate or prevent contamination of waters in the event of a refined product overflow, rupture, or leak from above-ground pipelines and storage tanks. The Clean Water Act also requires us to maintain spill prevention control and countermeasure plans at our terminal facilities with above-ground storage tanks and pipelines.
 The U.S. Oil Pollution Act of 1990 ("OPA 90") amended certain provisions of the Clean Water Act as they relate to the release of petroleum products into navigable waters. OPA 90 subjects owners of facilities to strict, joint and potentially unlimited liability for containment and removal costs, natural resource damages and certain other consequences of an oil spill. State laws also impose requirements relating to the prevention of oil releases and the remediation of areas. In addition, the OPA 90 requires that most fuel transport and storage companies maintain and update various oil spill prevention and oil spill contingency plans. Facilities that are adjacent to water require the engagement of Federally Certified Oil Spill Response Organizations to be available to respond to a spill on water from above ground storage tanks or pipelines.
 Transportation and storage of refined products over and adjacent to water involves risk and potentially subjects us to strict, joint, and potentially unlimited liability for removal costs and other consequences of an oil spill where the spill is into navigable waters, along shorelines or in the exclusive economic zone of the United States. In the event of an oil spill into navigable waters, substantial liabilities could be imposed upon us. The Clean Water Act imposes restrictions and strict controls regarding the discharge of pollutants into navigable waters, with the potential of substantial liability for the violation of permits or permitting requirements.
 Other Government Regulation
 The Petroleum Marketing Practices Act (the "PMPA") is a federal law that governs the relationship between a refiner and a distributor, as well as between a distributor and branded dealer, pursuant to which the refiner or distributor permits a distributor or dealer to use a trademark in connection with the sale or distribution of motor fuel. Under the PMPA, we may not terminate or fail to renew a branded distributor contract, unless certain enumerated preconditions or grounds for termination or nonrenewal are met and we also comply with the prescribed notice requirements. Additionally, we are subject to state petroleum franchise laws as well as laws specific to gasoline retailers and dealers, including state laws that regulate our relationships with third parties to whom we lease sites and supply motor fuels. Finally, we are subject to laws regarding fuel standards. For more information, see "We are subject to federal laws related to the Renewable Fuel Standard" and "We are subject to federal, state and local laws and regulations that govern the product quality specifications of refined petroleum products we purchase, store, transport, and sell to our distribution customers" in "Item 1A. Risk Factors" in this Annual Report on Form 10-K.

 Employee Safety
 We are subject to the requirements of the Occupational Safety and Health Act ("OSHA") and comparable state statutes that regulate the protection of the health and safety of workers. In addition, OSHA's hazard communication standards require that information be maintained about hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities and citizens. We believe that we are in substantive compliance with the applicable OSHA requirements.
 Store Operations
 Our remaining retail locations are subject to regulation by federal agencies and to licensing and regulations by state and local health, sanitation, safety, fire and other departments relating to the development and operation of convenience stores, including regulations related to zoning and building requirements and the preparation and sale of food.
 Our operations are also subject to federal and state laws governing such matters as wage rates, overtime, working conditions and citizenship requirements. At the federal level, there are proposals under consideration from time to time to increase minimum wage rates.
 Human Capital Management
 As of December 31, 2023, we employed an aggregate of 2,389 employees, 328 of which are represented by labor unions. We and our subsidiaries believe that our relations with our employees are good.
 In order to accomplish our objectives, we must continue to attract and retain top talent. We seek to accomplish this by fostering a culture that is guided by our ethics and principles, that respects all people and cultures, and that focuses on health and safety.
 Ethics and Principles. We are committed to operating our business in a manner that honors and respects all people and the communities in which we do business. We recognize that people are our most valued resource, and we are committed to hiring and investing in employees who strive for excellence and live by our core values: working safely, corporate stewardship, ethics and integrity, entrepreneurial mindset, our people, excellence and results, and social responsibility. We value our employees for what they bring to our organization by embracing those from all backgrounds, cultures, and experiences. We also believe that the keys to our success have been the cultivation of an atmosphere of inclusion and respect within our family of partnerships and sustaining organizations that promote diversity and provide support across all communities. These are the principles upon which we build and strengthen relationships among our people, our stakeholders, and those within the communities we support.
 Respecting All People and All Cultures. We believe strict adherence to our Code of Business Conduct and Ethics is not only right, but is in the best interest of the Partnership, its unitholders, its customers, and the industry in general. The Partnership's policies require that business be conducted in a lawful and ethical manner at all times. Every employee acting on behalf of the Partnership must adhere to these policies. Please refer to "Item 10. Directors, Executive Officers and Corporate Governance" for additional information on our Code of Business Conduct and Ethics.
 Commitment to Safety. Our goal is operational excellence, which means an injury and incident-free workplace. To achieve this, we strive to hire and maintain a qualified and dedicated workforce and encourage safety and safety accountability throughout our daily operations.
 Our environmental, health and safety professionals provide environmental and safety training to our field representatives. This group also assists others throughout the organization in identifying continuous training for personnel, including the training that is required by applicable laws, regulations, standards, and permit conditions. Our safety standards and expectations are clearly communicated to all employees and contractors with the expectation that each individual has the obligation to make safety the highest priority. Our safety culture promotes an open environment for discovering, resolving, and sharing safety challenges. We strive to eliminate unwanted safety events through a comprehensive process that promotes leadership, employee involvement, communication, and personal responsibility to comply with standard operating procedures and regulatory requirements, effective risk reduction processes, maintaining clean facilities, contractor safety, and personal wellness.

 Item 1A. Risk Factors
 Below we have provided a summary of our key risk factors, followed by detail of these and other risks that should be reviewed when considering an investment in our securities. The risk factors set forth below are not all the risks we face and other factors that we face in the ordinary course of our business, that are currently considered immaterial or that are currently unknown to us may impact our future operations.

 • our potential to be taxed as a corporation or otherwise become subject to a material amount of entity-level taxation;
 • the potential for our unitholders to be required to pay taxes on their share of our income even if they do not receive any cash distributions from us; and
 • unique tax issues faced by tax-exempt entities from owning common units.
 Detail of Risk Factors Related to Our Business
 Results of Operations and Financial Condition
 Cash distributions are not guaranteed and may fluctuate with our performance and other external factors.
 Cash distributions to unitholders is principally dependent upon cash generated from operations. The amount of cash generated from operations will fluctuate from quarter to quarter based on a number of factors, some of which are beyond our control, which include, among others:
 • demand for motor fuel in the markets we serve, including the result of secular trends towards increased usage of electric vehicles and/or seasonal fluctuations in demand for motor fuel;
 • competition from other companies that sell motor fuel products or have convenience stores in the market areas in which we or our commission agents or dealers operate;
 • regulatory action affecting the supply of or demand for motor fuel, our operations, our existing contracts or our operating costs;
 • prevailing economic conditions;
 • rising interest rates and slowing economic growth;
 • the accelerated transition to a low carbon economy;
 • geopolitical events such as the armed conflict in Ukraine and political instability in the Middle East;
 • supply, extreme weather and logistics disruptions; and
 • volatility of margins for motor fuel.
 In addition, the actual amount of cash we will have available for distribution will depend on other factors such as:
 • the level and timing of capital expenditures we make;
 • the cost of acquisitions, if any;

 • our debt service requirements and other liabilities;
 • fluctuations in our general working capital needs;
 • reimbursements made to our General Partner and its affiliates for all direct and indirect expenses they incur on our behalf pursuant to the partnership agreement;
 • our ability to borrow funds at favorable interest rates and access capital markets, including as a result of recent increases in cost of capital resulting from Federal Reserve policies;
 • restrictions contained in debt agreements to which we are a party;
 • the level of costs related to litigation and regulatory compliance matters; and
 • the amount of cash reserves established by our General Partner in its discretion for the proper conduct of our business.
 If our cash flow from operations is insufficient to satisfy our needs, we cannot be certain that we will be able to obtain bank financing or access the capital markets. Further, incurring additional debt may significantly increase our interest expense and financial leverage and issuing additional limited partner interests may result in significant unitholder dilution and would increase the aggregate amount of cash required to maintain the cash distribution rate which could materially decrease our ability to pay distributions. If additional capital resources are unavailable to us, our business, financial condition, results of operations and ability to make distributions could be materially adversely affected.
 Our business could be negatively impacted by the inflationary pressures which may decrease our operating margins and increase working capital investments required to operate our business.
 The U.S. inflation rate steadily rose in 2021 and into 2022 before eventually declining throughout 2023. A sustained increase in inflation may continue to increase our costs for labor, services and materials, which, in turn, could cause our operating costs and capital expenditures to increase. Further, our customers face inflationary pressures and resulting impacts, such as the tight labor market and supply chain disruptions. The rate and scope of these various inflationary factors may increase our operating costs and capital expenditures materially, which may not be readily recoverable in the prices of our services and may have an adverse effect on our costs, operating margins, results of operations and financial condition. Additionally, the Federal Reserve and other central banks have implemented policies in an effort to curb inflationary pressure on the costs of goods and services across the U.S., including the significant increases in prevailing interest rates that occurred during 2022 and 2023 as a result of the 525 aggregate basis point increase in the federal funds rate, and the associated macroeconomic impact on slowdown in economic growth could negatively impact our business. While the Federal Reserve indicated in December 2023 that it may reduce benchmark interest rates in 2024, the continuation of rates at the current level could have the effects of raising the cost of capital and depressing economic growth, either of which—or the combination thereof—could hurt the financial and operating results of our business.
 General economic, financial, and political conditions may materially adversely affect our results of operations and financial condition.
 General economic, financial, and political conditions may have a material adverse effect on our results of operations and financial condition. For example, following the election of President Biden and passage of laws such as the IRA 2022, it is possible that our operations and the operations of the oil and gas industry may be subject to greater environmental, health, and safety restrictions. Similarly, declines in consumer confidence and/or consumer spending, changes in unemployment, significant inflationary or deflationary changes or disruptive regulatory or geopolitical events could contribute to increased volatility and diminished expectations for the economy and our markets, including the market for our goods and services, and lead to demand or cost pressures that could negatively and adversely impact our business. These conditions could affect both of our business segments.
 Examples of such conditions could include:
 • a general or prolonged decline in, or shocks to, regional or broader macro-economies;
 • regulatory changes that could impact the markets in which we operate, such as immigration or trade reform laws or regulations prohibiting or limiting hydraulic fracturing, which could reduce demand for or supply of our goods and services or lead to pricing, currency, or other pressures; and
 • deflationary economic pressures, which could hinder our ability to operate profitably in view of the challenges inherent in making corresponding deflationary adjustments to our cost structure.
 The nature of these types of risks, which are often unpredictable, makes them difficult to plan for, or otherwise mitigate, and they are generally uninsurable—which compounds their potential impact on our business.

 Our financial condition and results of operations are influenced by changes in the prices of motor fuel, which may adversely impact our margins, our customers' financial condition and the availability of trade credit.
 Our operating results are influenced by prices for motor fuel. General economic and political conditions, acts of war or terrorism and instability in oil producing regions, particularly in the Middle East, South America, Russia and Africa could significantly impact crude oil supplies and refined product petroleum costs. Significant increases or high volatility in petroleum costs could impact consumer demand for motor fuel and convenience merchandise. Such volatility makes it difficult to predict the impact that future petroleum costs fluctuations may have on our operating results and financial condition. We are subject to dealer tank wagon pricing structures at certain locations further contributing to margin volatility. A significant change in any of these factors could materially impact both wholesale and retail fuel margins, the volume of motor fuel we distribute or sell, and overall customer traffic, each of which in turn could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 Significant increases in wholesale motor fuel prices could impact us as some of our customers may have insufficient credit to purchase motor fuel from us at their historical volumes. Higher prices for motor fuel may also reduce our access to trade credit support or cause it to become more expensive.
 A significant decrease in demand for motor fuel, including increased consumer preference for alternative motor fuels or improvements in fuel efficiency or a material shift toward electric or other alternative-power vehicles, in the areas we serve would reduce our ability to make distributions to our unitholders.
 Sales of refined motor fuels accounted for approximately 98% of our total revenues and 69% of our profit for the year ended December 31, 2023. A significant decrease in demand for motor fuel in the areas we serve could significantly reduce our revenues and our ability to make distributions to our unitholders. Our revenues are dependent on various trends, such as trends in commercial truck traffic, travel and tourism in our areas of operation, and these trends can change. Regulatory action, including government imposed fuel efficiency standards, may also affect demand for motor fuel. Because certain of our operating costs and expenses are fixed and do not vary with the volumes of motor fuel we distribute, our costs and expenses might not decrease ratably or at all should we experience such a reduction. As a result, we may experience declines in our profit margin if our fuel distribution volumes decrease.
 Any technological advancements, regulatory changes or changes in consumer preferences causing a significant shift toward alternative motor fuels could reduce demand for the conventional petroleum based motor fuels we currently sell. Additionally, a shift toward electric, hydrogen, natural gas or other alternative-power vehicles could fundamentally change our customers' shopping habits or lead to new forms of fueling destinations or new competitive pressures.
 New technologies have been developed and governmental mandates have been implemented to improve fuel efficiency, which may result in decreased demand for petroleum-based fuel. For example, in December 2021, the Biden Administration announced revised GHG emissions standards for light-duty vehicle fleets for Model Years 2023-2026, which some manufacturers may meet by increasing fuel efficiency or increasing the prevalence of zero-emissions vehicles in their fleets. The Biden Administration has also set a goal for federal vehicle acquisitions to be 100% zero-emissions vehicles by 2035, which may further influence the composition of vehicle fleets. Laws such as the Bipartisan Infrastructure Act and the IRA 2022 allocate funds to the development of electric vehicle infrastructure and provide incentives for consumers and manufacturers related to their use or development of electric vehicles, and the adoption rate of electric vehicles in the U.S. has continued to accelerate, with projections for the future rate of adoption in some reports more than doubling in recent years. Any of these actions could result in fewer visits to our convenience stores or independently operated commission agents and dealer locations, a reduction in demand from our wholesale customers, decreases in both fuel and merchandise sales revenue, or reduced profit margins, any of which could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 The industries in which we operate are subject to seasonal trends, which may cause our operating costs to fluctuate, affecting our cash flow.
 We rely in part on consumer travel and spending patterns, and may experience more demand for gasoline in the late spring and summer months than during the fall and winter. Travel, recreation and construction are typically higher in these months in the geographic areas in which we or our commission agents and dealers operate, increasing the demand for motor fuel that we sell and distribute. Therefore, our revenues and cash flows are typically higher in the second and third quarters of our fiscal year. As a result, our results from operations may vary widely from period to period, affecting our cash flow.
 The dangers inherent in the storage and transportation of motor fuel could cause disruptions in our operations and could expose us to potentially significant losses, costs or liabilities.
 We store motor fuel in underground and above ground storage tanks. We transport the majority of our motor fuel in our own trucks, instead of by third-party carriers. Our operations are subject to significant hazards and risks inherent in transporting and storing motor fuel. These hazards and risks include, but are not limited to, traffic accidents, fires, explosions, spills, discharges, and other releases, any of which could result in distribution difficulties and disruptions, environmental pollution, governmentally-imposed fines

 or clean-up obligations, personal injury or wrongful death claims, and other damage to our properties and the properties of others. Any such event not covered by our insurance could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 Our fuel storage terminals are subject to operational and business risks which may adversely affect our financial condition, results of operations, cash flows and ability to make distributions to our unitholders.
 Our fuel storage terminals are subject to operational and business risks, the most significant of which include the following:
 • our inability to renew a ground lease for certain of our fuel storage terminals on similar terms or at all;
 • our dependence on third parties to supply our fuel storage terminals;
 • outages at our fuel storage terminals or interrupted operations due to weather-related or other natural causes;
 • the threat that the nation's terminal infrastructure may be a future target of terrorist organizations;
 • the volatility in the prices of the products stored at our fuel storage terminals and the resulting fluctuations in demand for our storage services;
 • the effects of a sustained recession or other adverse economic conditions;
 • the possibility of federal and/or state regulations that may discourage our customers from storing gasoline, diesel fuel, ethanol and jet fuel at our fuel storage terminals or reduce the demand by consumers for petroleum products;
 • competition from other fuel storage terminals that are able to supply our customers with comparable storage capacity at lower prices; and
 • climate change legislation or regulations that restrict emissions of GHGs could result in increased operating and capital costs and reduced demand for our storage services.
 The occurrence of any of the above situations, among others, may affect operations at our fuel storage terminals and may adversely affect our business, financial condition, results of operations, cash flows and ability to make distributions to our unitholders.
 Negative events or developments associated with our branded suppliers could have an adverse impact on our revenues.
 We believe that the success of our operations is dependent, in part, on the continuing favorable reputation, market value, and name recognition associated with the motor fuel brands sold at our convenience stores and at stores operated by our independent, branded dealers and commission agents. Erosion of the value of those brands could have an adverse impact on the volumes of motor fuel we distribute, which in turn could have a material adverse effect on our business, financial condition, results of operations and ability to make distributions to our unitholders.
 Severe weather, which may increase in frequency and intensity due to climate change, could adversely affect our business by damaging our suppliers' or our customers' facilities or communications networks.
 A substantial portion of our wholesale distribution and retail networks are located in regions susceptible to severe storms, including hurricanes. A severe storm could damage our facilities or communications networks, or those of our suppliers or our customers, as well as interfere with our ability to distribute motor fuel to our customers or our customers' ability to operate their locations. If warmer temperatures, or other climate changes, lead to changes in extreme weather events, including increased frequency, duration or severity, these weather-related risks could become more pronounced. Any weather-related catastrophe or disruption could have a material adverse effect on our business, financial condition and results of operations, potentially causing losses beyond the limits of the insurance we currently carry.
 The wholesale motor fuel distribution industry is characterized by intense competition and fragmentation. Failure to effectively compete could result in lower margins.
 The market for distribution of wholesale motor fuel is highly competitive and fragmented, which results in narrow margins. We have numerous competitors, some of which may have significantly greater resources and name recognition than us. We rely on our ability to provide value-added, reliable services and to control our operating costs in order to maintain our margins and competitive position. If we fail to maintain the quality of our services, certain of our customers could choose alternative distribution sources and our margins could decrease. While major integrated oil companies have generally continued a strategy of limited direct retail operation and the corresponding wholesale distribution to such sites, such major oil companies could shift from this strategy and decide to distribute their own products in direct competition with us, or large customers could attempt to buy directly from the major oil companies. The occurrence of any of these events could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.

 The convenience store industry is highly competitive and impacted by new entrants. Failure to effectively compete could result in lower sales and lower margins.
 The geographic areas in which we operate and supply independently operated commission agent and dealer locations are highly competitive and marked by ease of entry and constant change in the number and type of retailers offering products and services of the type we and our independently operated commission agents and dealers sell in our stores. Our convenience stores and the commission agents and dealer locations we supply compete with other convenience store chains, independently owned convenience stores, motor fuel stations, supermarkets, drugstores, discount stores, dollar stores, club stores, mass merchants and local restaurants. Over the past two decades, several non-traditional retailers, such as supermarkets, hypermarkets, club stores and mass merchants, have impacted the convenience store industry, particularly in the geographic areas in which we operate and supply, by entering the motor fuel retail business. These non-traditional motor fuel retailers have captured a significant share of the motor fuels market, and we expect their market share will continue to grow.
 In some of our markets, our competitors have been in existence longer and have greater financial, marketing, and other resources than we or our independently operated commission agents and dealers do. As a result, our competitors may be able to respond better to changes in the economy and new opportunities within the industry. To remain competitive, we must constantly analyze consumer preferences and competitors' offerings and prices to ensure that we offer a selection of convenience products and services at competitive prices to meet consumer demand. We must also maintain and upgrade our customer service levels, facilities and locations to remain competitive and attract customer traffic to our stores. We may not be able to compete successfully against current and future competitors, and competitive pressures faced by us could have a material adverse effect on our business, results of operations and cash available for distribution to our unitholders.
 We do not own all of the land on which our retail service stations are located, and we lease certain facilities and equipment, and we are subject to the possibility of increased costs to retain necessary land use which could disrupt our operations.
 We do not own all of the land on which our retail service stations are located. We have rental agreements for approximately 33% of the partnership, commission agent or dealer operated retail service stations where we currently control the real estate. We also have rental agreements for certain logistics facilities. As such, we are subject to the possibility of increased costs under rental agreements with landowners, primarily through rental increases and renewals of expired agreements. We are also subject to the risk that such agreements may not be renewed. Additionally, certain facilities and equipment (or parts thereof) used by us are leased from third parties for specific periods. Our inability to renew leases or otherwise maintain the right to utilize such facilities and equipment on acceptable terms, or the increased costs to maintain such rights, could have a material adverse effect on our financial condition, results of operations and cash flows.
 Future litigation could adversely affect our financial condition and results of operations.
 We are exposed to various litigation claims in the ordinary course of our wholesale business operations, including dealer litigation and industry-wide or class-action claims arising from the products we carry, the equipment or processes we use or employ or industry-specific business practices. If we were to become subject to any such claims, our defense costs and any resulting awards or settlement amounts may not be fully covered by our insurance policies. Additionally, our retail operations are characterized by a high volume of customer traffic and by transactions involving a wide array of product selections. These operations carry a higher exposure to consumer litigation risk when compared to the operations of companies operating in many other industries. Consequently, we are frequently party to individual personal injury, bad fuel, products liability and other legal actions in the ordinary course of our business. While we believe these actions are generally routine in nature, incidental to the operation of our business and immaterial in scope, if our assessment of any action or actions should prove inaccurate our financial condition and results of operations could be adversely affected. Additionally, several fossil fuel companies have been the targets of litigation alleging, among other things, that such companies created public nuisances by producing and marketing fuels that contributed to climate change or that the companies have been aware of the adverse effects of climate change but failed to adequately disclose those impacts. While we cannot predict the likelihood of success of such suits, to the extent the plaintiffs prevail, we could face significant costs or decreased demand for our services, which could adversely affect our financial condition and results of operations.
 Because we depend on our senior management's experience and knowledge of our industry, we could be adversely affected were we to lose key members of our senior management team.
 We are dependent on the expertise and continued efforts of our General Partner's senior management team. If, for any reason, our senior executives do not continue to be active, our business, financial condition, or results of operations could be adversely affected. We do not maintain key man life insurance for our senior executives or other key employees.
 We compete with other businesses in our market with respect to attracting and retaining qualified employees.
 Our continued success depends on our ability to attract and retain qualified personnel in all areas of our business. We compete with other businesses in our market with respect to attracting and retaining qualified employees. A tight labor market, increased overtime and a higher full-time employee ratio may cause labor costs to increase. A shortage of qualified employees may require us to

 enhance wage and benefits packages in order to compete effectively in the hiring and retention of such employees or to hire more expensive temporary employees. No assurance can be given that our labor costs will not increase, or that such increases can be recovered through increased prices charged to customers. We are especially vulnerable to labor shortages in oil and gas drilling areas when energy prices drive higher exploration and production activity.
 We are not fully insured against all risks incident to our business.
 We are not fully insured against all risks incident to our business. We may be unable to obtain or maintain insurance with the coverage that we desire at reasonable rates. As a result of market conditions, the premiums and deductibles for certain of our insurance policies have increased and could continue to do so. Certain insurance coverage could become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our business, financial condition, results of operations and ability to make distributions to our unitholders.
 Terrorist attacks and threatened or actual war may adversely affect our business.
 Our business is affected by general economic conditions and fluctuations in consumer confidence and spending, which can decline as a result of numerous factors outside of our control. Terrorist attacks or threats, whether within the United States or abroad, rumors or threats of war, actual conflicts involving the United States or its allies, or military or trade disruptions impacting our suppliers or our customers may adversely impact our operations. Specifically, strategic targets such as energy related assets (which could include refineries that produce the motor fuel we purchase, ports in which crude oil is delivered or attacks to the electrical grid) may be at greater risk of future terrorist attacks than other targets in the United States. These occurrences could have an adverse impact on energy prices, including prices for motor fuels, and an adverse impact on our operations. Any or a combination of these occurrences could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 Cybersecurity attacks, data breaches and other disruptions affecting us, or our service providers, could materially and adversely affect our business, operations, reputation, and financial results.
 The security and integrity of our information technology ("IT") infrastructure and physical assets is critical to our business and our ability to perform day-to-day operations and deliver services. In addition, in the ordinary course of our business, we collect, process, transmit and store sensitive data, including intellectual property, our proprietary business information and that of our customers, suppliers and business partners, as well as personally identifiable information, in our data centers and on our networks. We also engage third parties, such as service providers and vendors, who provide a broad array of software, technologies, tools, and other products, services and functions (e.g., human resources, finance, data transmission, communications, risk, compliance, among others) that enable us to conduct, monitor and/or protect our business, operations, systems and data assets.
 Our IT and IT infrastructure, physical assets and data, may be vulnerable to unauthorized access, computer viruses, malicious attacks and other events (e.g., distributed denial of service attacks or ransomware attacks) that are beyond our control. These events can result from malfeasance by external parties, such as hackers, or due to human error by our or our service providers' employees and contractors (e.g., due to social engineering or phishing attacks). In addition, our providers' work-from-home arrangements may present additional operational and cybersecurity risks to our IT infrastructure and physical assets.
 We and certain of our service providers have, from time to time, been subject to cybersecurity attacks and other security incidents. The frequency and magnitude of cybersecurity attacks is expected to increase and attackers are becoming more sophisticated. We may be unable to anticipate, detect or prevent future attacks, particularly as the methodologies used by attackers change frequently or are not recognized until launched, and we may be unable to investigate or remediate incidents because attackers are increasingly using techniques and tools designed to circumvent controls, to avoid detection, and to remove or obfuscate forensic evidence.
 Breaches of our IT infrastructure or physical assets, or other disruptions, could result in damage to our assets, safety incidents, damage to the environment, potential liability or the loss of contracts, and have a material adverse effect on our operations, financial position and results of operations. A successful cybersecurity attack or other security incident could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or loss could result in legal claims or proceedings, regulatory investigations and enforcement, penalties and fines, increased costs for system remediation and compliance requirements, disruption of our operations, damage to our reputation, loss of confidence in our products and services, any or all of which could have a material adverse effect on our business and results. We may be required to invest significant additional resources to comply with evolving cybersecurity regulations and to modify and enhance our information security and controls, and to investigate and remediate any security vulnerabilities. Any losses, costs or liabilities may not be covered by, or may exceed the coverage limits of, any or all of our applicable insurance policies. See "Item 1C. Cybersecurity" for additional information on our cybersecurity risk management, strategy and governance.

 We rely on our information systems to manage numerous aspects of our business, and a disruption of these systems could adversely affect our business.
 We depend on our information systems to manage numerous aspects of our business transactions and provide analytical information to management. Our information systems are an essential component of our business and growth strategies, and a serious disruption to our information systems could significantly limit our ability to manage and operate our business efficiently. These systems are vulnerable to, among other things, damage and interruption from power loss or natural disasters, computer system and network failures, loss of telecommunications services, physical and electronic loss of data, security breaches and computer viruses, which could result in a loss of sensitive business information, systems interruption or the disruption of our business operations. To protect against unauthorized access or attacks, we have implemented infrastructure protection technologies and disaster recovery plans, but there can be no assurance that a technology systems breach or systems failure will not have a material adverse effect on our financial condition or results of operations. See "Item 1C. Cybersecurity" for additional information on our cybersecurity risk management, strategy and governance.
 Our business and our reputation could be adversely affected by the failure to protect sensitive customer, employee or vendor data, whether as a result of cybersecurity attacks or otherwise, or to comply with applicable regulations relating to data security and privacy.
 In the normal course of our business as a motor fuel, food service and merchandise retailer, we obtain large amounts of personal data, including credit and debit card information from our customers. In recent years several retailers have experienced data breaches resulting in exposure of sensitive customer data, including payment card information. While we have invested significant amounts in the protection of our information systems and maintain what we believe are adequate security controls over individually identifiable customer, employee and vendor data provided to us, a breakdown or a breach in our systems that results in the unauthorized release of individually identifiable customer or other sensitive data could nonetheless occur and have a material adverse effect on our reputation, operating results and financial condition. Such a breakdown or breach could also materially increase the costs we incur to protect against such risks. Also, a material failure on our part to comply with regulations relating to our obligation to protect such sensitive data or to the privacy rights of our customers, employees and others could subject us to fines or other regulatory sanctions and potentially to lawsuits.
 Cybersecurity attacks are rapidly evolving and becoming increasingly sophisticated. A successful cybersecurity attack resulting in the loss of sensitive customer, employee or vendor data could adversely affect our reputation, results of operations, financial condition and liquidity, and could result in litigation against us or the imposition of penalties. Moreover, a security breach could require that we expend significant additional resources to upgrade further the security measures that we employ to guard against cybersecurity attacks. See "Item 1C. Cybersecurity" for additional information on our cybersecurity risk management, strategy and governance.
 We rely on our suppliers to provide trade credit terms to adequately fund our ongoing operations.
 Our business is impacted by the availability of trade credit to fund fuel purchases. An actual or perceived downgrade in our liquidity or operations (including any credit rating downgrade by a rating agency) could cause our suppliers to seek credit support in the form of additional collateral, limit the extension of trade credit, or otherwise materially modify their payment terms. Any material changes in our payment terms, including early payment discounts, or availability of trade credit provided by our principal suppliers could impact our liquidity, results of operations and cash available for distribution to our unitholders.
 We depend on cash flow generated by our subsidiaries.
 We are a holding company with no material assets other than the equity interests in our subsidiaries. Our subsidiaries conduct all of our operations and own all of our assets. These subsidiaries are distinct legal entities and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries and our subsidiaries may not be able to, or be permitted to, make distributions to us. There are significant restrictions that the agreements governing the Partnership's debt impose on the ability of these subsidiaries to make distributions and other payments to us, including restrictions on the ability of these subsidiaries to transfer funds to us in the form of dividends, loans or advances. In the event that we do not receive distributions from our subsidiaries, we may be unable to meet our financial obligations or make distributions to our unitholders.
 An impairment of goodwill and intangible assets could reduce our earnings.
 As of December 31, 2023, our consolidated balance sheet reflected $1.60 billion of goodwill and $544 million of intangible assets. Goodwill is recorded when the purchase price of a business exceeds the fair value of the tangible and separately measurable intangible net assets. Generally accepted accounting principles ("GAAP") require us to test goodwill and indefinite-lived intangible assets for impairment on an annual basis or when events or circumstances occur, indicating that goodwill or indefinite-lived intangible assets might be impaired. Long-lived assets such as intangible assets with finite useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If we determine that any of our goodwill or intangible assets were impaired, we would be required to take an immediate charge to earnings with a correlative effect on partners'

 capital and balance sheet leverage as measured by debt to total capitalization. Impairment charges are allowed to be removed from our debt covenant calculations. See Note 7 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data."
 Acquisitions and Future Growth
 If we are unable to make acquisitions on economically acceptable terms from third parties, our future growth and ability to increase distributions to unitholders will be limited.
 A portion of our strategy to grow our business is dependent on our ability to make acquisitions that result in an increase in cash flow. The acquisition component of our growth strategy is based, in part, on our expectation of ongoing strategic divestitures of wholesale fuel distribution assets by industry participants. If we are unable to make acquisitions from third parties for any reason, including if we are unable to identify attractive acquisition candidates or negotiate acceptable purchase contracts, we are unable to obtain financing for these acquisitions on economically acceptable terms, we are outbid by competitors, or we or the seller are unable to obtain all necessary consents, our future growth and ability to increase distributions to unitholders will be limited. In addition, if we consummate any future acquisitions, our capitalization and results of operations may change significantly, and unitholders will not have the opportunity to evaluate the economic, financial, and other relevant information considered in determining the application of these funds and other resources. Finally, we may complete acquisitions which at the time of completion we believe will be accretive, but which ultimately may not be accretive. If any of these events were to occur, our future growth would be limited.
 Integration of assets acquired in past acquisitions or future acquisitions with our existing business will be a complex, time-consuming and costly process, particularly given that assets acquired to date significantly increased our size and diversified the geographic areas in which we operate. A failure to successfully integrate the acquired assets with our existing business in a timely manner may have a material adverse effect on our business, financial condition, results of operations or cash available for distribution to our unitholders.
 The difficulties of integrating past and future acquisitions with our business include, among other things:
 • operating a larger combined organization in new geographic areas and new lines of business;
 • hiring, training or retaining qualified personnel to manage and operate our growing business and assets;
 • integrating management teams and employees into existing operations and establishing effective communication and information exchange with such management teams and employees;
 • diversion of management's attention from our existing business;
 • assimilation of acquired assets and operations, including additional regulatory programs;
 • loss of customers or key employees;
 • maintaining an effective system of internal controls in compliance with the Sarbanes-Oxley Act of 2002 as well as other regulatory compliance and corporate governance matters; and
 • integrating new technology systems for financial reporting.
 If any of these risks or other unanticipated liabilities or costs were to materialize, then desired benefits from past acquisitions and future acquisitions could result in a negative impact to our future results of operations. In addition, acquired assets may perform at levels below the forecasts used to evaluate them, due to factors beyond our control. If the acquired assets perform at levels below the forecasts, then our future results of operations could be negatively impacted.
 Also, our reviews of proposed business or asset acquisitions are inherently imperfect because it is generally not feasible to perform an in-depth review of each such proposal given time constraints imposed by sellers. Even if performed, a detailed review of assets and businesses may not reveal existing or potential problems, and may not provide sufficient familiarity with such business or assets to fully assess their deficiencies and potential. Inspections may not be performed on every asset, and environmental problems, such as groundwater contamination, may not be observable even when an inspection is undertaken.
 Acquisitions are subject to substantial risks that could adversely affect our financial condition and results of operations and reduce our ability to make distributions to unitholders.
 Any acquisitions involve potential risks, including, among others:
 • the validity of our assumptions about revenues, capital expenditures and operating costs of the acquired business or assets, as well as assumptions about achieving synergies with our existing business;

 • the validity of our assessment of environmental and other liabilities, including legacy liabilities;
 • the costs associated with additional debt or equity capital, which may result in a significant increase in our interest expense and financial leverage resulting from any additional debt incurred to finance the acquisition, or the issuance of additional common units on which we will make distributions, either of which could offset the expected accretion to our unitholders from such acquisition and could be exacerbated by volatility in the equity or debt capital markets;
 • a failure to realize anticipated benefits, such as increased available cash per unit, enhanced competitive position or new customer relationships;
 • a decrease in our liquidity by using a significant portion of our available cash or borrowing capacity to finance the acquisition;
 • the incurrence of other significant charges, such as impairment of goodwill or other intangible assets, asset devaluation or restructuring charges; and
 • the risk that our existing financial controls, information systems, management resources and human resources will need to grow to support future growth and we may not be able to react timely.
 Our unitholders will have a reduced ownership in us after our acquisition of NuStar.
 Pursuant to that certain Agreement and Plan of Merger, dated January 22, 2024, NuStar unitholders have the right to receive 0.400 of our common unit per each NuStar common unit. The actual number of our common units to be issued will be determined at the completion of the acquisition based on the number of NuStar common units outstanding immediately prior to such time. The issuance of these new units could have the effect of depressing the market price of our common units, through dilution of earnings per share or otherwise. Any dilution of, or delay of any accretion to, our earnings per share could cause the price of our common units to decline or increase at a reduced rate.
 Failure to complete the acquisition of NuStar and successfully integrate the businesses of SUN and NuStar in the expected time frame could negatively impact the price of our common units and have a material adverse effect on our results of operations, cash flows and financial position.
 If our acquisition of NuStar is not completed for any reason, including as a result of failure to obtain all requisite regulatory approvals or our unitholders fail to approve the applicable proposals, the anticipated benefits of the acquisition may not be realized or may take longer to realize than expected. The success of the merger will depend, in part, on the ability of the Partnership to realize the anticipated benefits from combining the businesses of SUN and NuStar. If SUN and NuStar are unable to successfully combine their businesses, the anticipated benefits of the merger may take longer to realize than expected. In addition, the actual integration may result in additional and unforeseen expenses, which could reduce the anticipated benefits of the merger.
 Additionally, we would be subject to a number of risks, including the following:
 • negative reactions from the financial markets, including negative impacts on the price of our common units;
 • negative reactions from our respective customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners;
 • we will still be obligated to pay certain significant costs relating to our acquisition of NuStar, such as legal, accounting, financing, financial advisor and printing fees;
 • we may be obligated to pay a termination fee as required by the merger agreement governing the acquisition;
 • the merger agreement governing the acquisition places certain restrictions on the conduct of our business, which may delay or prevent the undertaking of business opportunities that, absent the merger agreement governing the acquisition, may have been pursued;
 • matters relating to our acquisition of NuStar (including integration planning) require substantial commitments of time and resources by management, which may have resulted in the distraction from ongoing business operations and pursuing other opportunities that could have been beneficial;
 • litigation related to any failure to complete our acquisition of NuStar or related to any enforcement proceeding commenced against us to perform our respective obligations under the merger agreement governing the acquisition; and

 • loss of key employees, the disruption of each of SUN's and NuStar's ongoing businesses and relationships with customers, or inconsistencies in their standards, controls, procedures and policies.
 If the acquisition is not completed, the risks described above may materialize and they may have a material adverse effect on our results of operations, cash flows, financial position and price of our common units.
 The Inflation Reduction Act of 2022 could accelerate the transition to a low carbon economy and could impose new costs on our operations.
 In August 2022, President Biden signed the IRA 2022, which contains hundreds of billions in incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles and supporting infrastructure and carbon capture and sequestration, amongst other provisions. In addition, the IRA 2022 imposes the first ever federal fee on the emission of GHGs through a methane emissions charge. The IRA 2022 amends the Clean Air Act to impose a fee on the emission of methane from sources required to report their GHG emissions to the EPA, including those sources in the onshore petroleum and natural gas production categories. The methane emissions charge has started in calendar year 2024 at $900 per ton of methane, will increase to $1,200 in 2025, and be set at $1,500 for 2026 and each year after. Calculation of the fee is based on certain thresholds established in the IRA 2022. In addition, the multiple incentives offered for various clean energy industries referenced above could further accelerate the transition of the economy away from the use of fossil fuels towards lower- or zero-carbon emissions alternatives. This could decrease demand for gasoline and diesel, increase our compliance and operating costs and consequently adversely affect our business.
 Regulatory Matters
 Our operations are subject to federal, state and local laws and regulations pertaining to environmental protection and operational safety that may require significant expenditures or result in liabilities that could have a material adverse effect on our business.
 Our business is subject to various federal, state and local environmental laws and regulations, including those relating to terminals, underground storage tanks, the release or discharge of regulated materials into the air, water and soil, the generation, storage, handling, use, transportation and disposal of hazardous materials, the exposure of persons to regulated materials, and the health and safety of our employees. A violation of, liability under, or noncompliance with these laws and regulations, or any future environmental law or regulation, could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 Regulations under the Clean Water Act, the Oil Pollution Act of 1990 ("OPA 90") and state laws impose regulatory burdens on terminal operations. Spill prevention control and countermeasure requirements of federal and state laws require containment to mitigate or prevent contamination of waters in the event of a refined product overflow, rupture, or leak from above-ground pipelines and storage tanks. The Clean Water Act also requires us to maintain spill prevention control and countermeasure plans at our terminal facilities with above-ground storage tanks and pipelines. In addition, OPA 90 requires that most fuel transport and storage companies maintain and update various oil spill prevention and oil spill contingency plans. Facilities that are adjacent to water require the engagement of Federally Certified Oil Spill Response Organizations to be available to respond to a spill on water from above ground storage tanks or pipelines.
 Transportation and storage of refined products over and adjacent to water involves risk and potentially subjects us to strict, joint, and potentially unlimited liability for removal costs and other consequences of an oil spill where the spill is into navigable waters, along shorelines or in the exclusive economic zone of the United States. In the event of an oil spill into navigable waters, substantial liabilities could be imposed upon us. The Clean Water Act imposes restrictions and strict controls regarding the discharge of pollutants into navigable waters, with the potential of substantial liability for the violation of permits or permitting requirements.
 Terminal operations and associated facilities are subject to the Clean Air Act as well as comparable state and local statutes. Under these laws, permits may be required before construction can commence on a new source of potentially significant air emissions, and operating permits may be required for sources that are already constructed. If regulations become more stringent, additional emission control technologies may be required at our facilities. Any such future obligation could require us to incur significant additional capital or operating costs. For more information, see our regulatory disclosure titled "Air Emissions and Climate Change."
 Terminal operations are subject to additional programs and regulations under OSHA. Liability under, or a violation of compliance with, these laws and regulations, or any future laws or regulations, could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 Certain environmental laws, including CERCLA, impose strict, and under certain circumstances, joint and several, liability on the current and former owners and operators of properties for the costs of investigation and removal or remediation of contamination and also impose liability for any related damages to natural resources without regard to fault. Under CERCLA and similar state laws, as persons who arrange for the transportation, treatment, and disposal of hazardous substances, we may also be subject to liability at sites where such hazardous substances come to be located. We may be subject to third-party claims alleging property damage and/or personal injury in connection with releases of or exposure to hazardous substances at, from, or in the vicinity of our current or former

 properties or off-site waste disposal sites. Costs associated with the investigation and remediation of contamination, as well as associated third-party claims, could be substantial, and could have a material adverse effect on our business, financial condition, results of operations and our ability to service our outstanding indebtedness. In addition, the presence of, or failure to remediate, identified or unidentified contamination at our properties could materially and adversely affect our ability to sell or rent such property or to borrow money using such property as collateral.
 We are required to make financial expenditures to comply with regulations governing underground storage tanks as adopted by federal, state and local regulatory agencies. Compliance with existing and future environmental laws regulating underground storage tank systems of the kind we use may require significant capital expenditures. For example, the EPA has previously published rules that amend existing federal underground storage tank rules, requiring certain upgrades to underground storage tanks and related piping to further ensure the detection, prevention, investigation, and remediation of leaks and spills.
 We are required to comply with federal and state financial responsibility requirements to demonstrate that we have the ability to pay for cleanups or to compensate third parties for damages incurred as a result of a release of regulated materials from our underground storage tank systems. We seek to comply with these requirements by maintaining insurance that we purchase from private insurers and in certain circumstances, rely on applicable state trust funds, which are funded by underground storage tank registration fees and taxes on wholesale purchases of motor fuels. Coverage afforded by each fund varies and is dependent upon the continued maintenance and solvency of each fund.
 We are responsible for investigating and remediating contamination at a number of our current and former properties. We are entitled to reimbursement for certain of these costs under various third-party contractual indemnities and insurance policies, subject to eligibility requirements, deductibles, per incident, annual and aggregate caps. To the extent third parties (including insurers) do not pay for investigation and remediation, and/or insurance is not available, we will be obligated to make these additional payments, which could have a material adverse impact on our business, liquidity, results of operations and cash available for distribution to our unitholders.
 We believe we are in material compliance with applicable environmental requirements; however, we cannot ensure that violations of these requirements will not occur in the future. Although we believe that we have a comprehensive environmental, health, and safety program, we may not have identified all environmental liabilities at all of our current and former locations; material environmental conditions not known to us may exist; existing and future laws, ordinances or regulations may impose material environmental liability or compliance costs on us; or we may be required to make material environmental expenditures for remediation of contamination that has not been discovered at existing locations or locations that we may acquire.
 The occurrence of any of the events described above could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 Our operations are subject to a series of risks related to climate change.
 The threat of climate change continues to attract considerable attention in the United States and in foreign countries. In the United States to date, no comprehensive climate change legislation has been implemented at the federal level. However, President Biden has announced that climate change will be a focus of his administration. On January 27, 2021, he issued an executive order calling for substantial action on climate change, including, among other things, the increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry, and increased emphasis on climate-related risks across agencies and economic sectors. Additionally, federal regulators, state and local governments, and private parties have taken (or announced that they plan to take) actions related to climate change that have or may have a significant impact on our operations. For example, in response to findings that emissions of carbon dioxide, methane and other GHGs endanger public health and the environment, the EPA has adopted regulations under existing provisions of the Clean Air Act that, among other things, establish PSD construction and Title V operating permit reviews for certain large stationary sources that are already potential major sources of certain principal, or criteria, pollutant emissions. Facilities required to obtain PSD permits for their GHG emissions also will be required to meet "best available control technology" standards that will be established by the states or, in some cases, by the EPA for those emissions. The EPA has also adopted rules requiring the monitoring and reporting of GHG emissions from certain sources in the United States on an annual basis, including certain of our operations; moreover, as part of President Biden's focus on climate change, the EPA has proposed new methane standards for both new and existing sources in the oil and gas sector. For more information, see our regulatory disclosure titled "Air Emissions and Climate Change."
 In August 2022, the IRA 2022 was signed into law, which appropriates significant federal funding for renewable energy initiatives and amends the Clean Air Act to impose a first-time fee on the emission of methane from sources required to report their GHG emissions to the EPA. The IRA 2022 imposes a methane emissions charge on sources required to report their GHG emissions to the EPA, which has started in calendar year 2024 at $900 per ton of methane, will increase to $1,200 in 2025, and be set at $1,500 for 2026 and each year after. Calculation of the fee is based on certain thresholds established in the IRA 2022.
 Internationally, the United Nations-sponsored "Paris Agreement" requires member states to individually determine and submit non-binding emissions reduction targets every five years after 2020. President Biden has recommitted the United States to the Paris

 agreement and, in April 2021, announced a goal of reducing the United States' emissions by 50-52% below 2005 levels by 2030. Additionally, at COP26 in Glasgow in November 2021, the United States and the European Union jointly announced the launch of a Global Methane Pledge, an initiative committing to a collective goal of reducing global methane emissions by at least 30% from 2020 levels by 2030, including "all feasible reductions" in the energy sector. At COP27 in Sharm El-Sheik in November 2022, countries reiterated the agreements from COP26 and were called upon to accelerate efforts toward the phase-out of fossil fuel subsidies. The United States also announced, in conjunction with the European Union and other partner countries, that it would develop standards for monitoring and reporting methane emissions to help create a market for low methane-intensity natural gas. At COP28 in December 2023, the parties signed onto an agreement to transition away from fossil fuels in energy systems and increase renewable energy capacity, though no timeline for doing so was set. While non-binding, the agreements coming out of COP28 could result in increased pressure among financial institutions and various stakeholders to reduce or otherwise impose more stringent limitations on funding for and increase potential opposition to the exploration and production of fossil fuels. Although no firm commitment or timeline to phase out or phase down all fossil fuels was made at COP27 or COP28, there can be no guarantees that countries will not seek to implement such a phase out in the future. The full impact of these actions is uncertain at this time. However, any efforts to control and/or reduce GHG emissions by the United States or other countries, or concerted conservation efforts that result in reduced consumption, could adversely impact demand for our products and, in turn, our financial position and results of operations. Increasingly, fossil fuel companies are also exposed to litigation risks from climate change.
 Additionally, in response to concerns related to climate change, companies in the fossil fuel sector may be exposed to increasing financial risks. For example, at COP26, the GFANZ announced that commitments from over 450 firms across 45 countries had resulted in over $130 trillion in capital committed to net zero goals. The various sub-alliances of GFANZ generally require participants to set short-term, sector-specific targets to transition their financing, investing, and/or underwriting activities to net zero emissions by 2050. There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. The Federal Reserve has joined the NGFS, a consortium of financial regulators focused on addressing climate-related risks in the financial sector, and, in November 2021, the Federal Reserve issued a statement in support of the efforts of the NGFS to identify key issues and potential solutions for the climate-related challenges most relevant to central banks and supervisory authorities. In September 2022, the Federal Reserve announced that six of the United States' largest banks will participate in a pilot climate scenario analysis exercise to enhance the ability of firms and supervisors to measure and manage climate-related financial risk. Participant instructions for this exercise were released in January 2023, and initial responses from the banks were due on July 31, 2023, with the exercise concluded at the end of 2023. While we cannot predict what polices may result from these developments, a material reduction in the capital available to the fossil fuel industry could make it more difficult to secure funding for exploration, development, production, transportation, and processing activities, or for us to obtain funding for growth projects, and consequently could both indirectly affect demand for our services and directly affect our ability to fund construction or other capital projects. Additionally, in 2023 the SEC released a proposed rule that would require climate disclosures from registrants. Similarly, California has recently enacted a set of laws that may require climate-related disclosures from companies "doing business in California" with certain total annual revenue amounts. For more information, see our regulatory disclosure titled "Air Emissions and Climate Change." Although the final form and substance of these requirements is not yet known, these rules and laws may result in additional costs to comply with any such disclosure requirements.
 Climate change may also result in various physical risks, such as the increased frequency or intensity of extreme weather events or changes in meteorological and hydrological patterns that could adversely impact our operations or those of our supply chains. Such physical risks may result in damage to our facilities or otherwise adversely impact our operations, such as to the extent changing weather and temperature trends reduce the demand for our products or frequency with which consumers may visit our locations or impact the cost or availability of insurance. Moreover, certain parties, including local and state governments, have from time to time filed lawsuits against various fossil fuel energy companies seeking damages for alleged physical impacts resulting from climate change or relating to false or misleading statements related to fossil fuel's contribution to climate change. These various political, regulatory, financial, physical and litigation risks related to climate change have the potential adversely impact our operations and financial performance.
 A climate-related decrease in demand for crude oil could negatively affect our business.
 Supply and demand for crude oil is dependent upon a variety of factors, many of which are beyond our control. These factors include, among others, the potential adoption of new government regulations, including those related to fuel conservation measures and climate change regulations, technological advances in fuel economy and energy generation devices. For example, legislative, regulatory or executive actions intended to reduce emissions of GHGs could increase the cost of consuming crude oil, thereby potentially causing a reduction in the demand for this product. A broader transition to alternative fuels or energy sources, whether resulting from potential new government regulation, carbon taxes, governmental incentives and funding such as those provided in the IRA 2022, or consumer preferences could result in decreased demand for products like crude oil. Any decrease in demand could consequently reduce demand for our services and could have a negative effect on our business.

 Increased attention to environmental, social and governance ("ESG") matters and conservation measures may adversely impact our business.
 Increasing attention to climate change, societal expectations on companies to address climate change and other ESG matters, investor and societal expectations regarding voluntary ESG disclosures, and consumer demand for alternative forms of energy may result in increased costs, reduced demand for our products, reduced profits, increased investigations and litigation, and negative impacts on our common unit price and access to capital markets. Increasing attention to climate change and environmental conservation, for example, may result in reduced demand for fossil fuel products and additional governmental investigations and private litigation against us. To the extent that societal pressures or political or other factors are involved, it is possible that such liability could be imposed without regard to our causation of or contribution to climate change or asserted damage to the environment, or to other mitigating factors.
 Moreover, while we may create and publish voluntary disclosures regarding ESG matters from time to time, many of the statements in those voluntary disclosures may be based on expectations and assumptions. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters.
 In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings and recent activism directed at shifting funding away from companies with fossil fuel-related assets could lead to increased negative investor sentiment toward us and our industry and to the diversion of investment to other industries, which could have a negative impact on our common unit price and our access to and costs of capital. Also, institutional lenders may decide not to provide funding for fossil fuel companies based on climate change related concerns, which could affect our access to capital.
 We are subject to federal laws related to the RFS.
 New laws, new interpretations of existing laws, increased governmental enforcement of existing laws or other developments could require us to make additional capital expenditures or incur additional liabilities. For example, at times, certain independent refiners have initiated discussions with the EPA to change the way the RFS is administered in an attempt to shift the burden of compliance from refiners and importers to blenders and distributors. Under the RFS, which requires an annually increasing amount of biofuels to be blended into the fuels used by U.S. drivers, refiners/importers are obligated to obtain renewable identification numbers ("RINs") either by blending biofuel into gasoline or through purchase in the open market. If the obligation was shifted from the importer/refiner to the blender/distributor, the Partnership would potentially have to utilize the RINs it obtains through its blending activities to satisfy a new obligation and would be unable to sell RINs to other obligated parties, which may cause an impact on the fuel margins associated with the Partnership's sale of gasoline. Additionally, the price of RINs is not fixed and is subject to change due to various considerations, including regulatory actions. In June 2023, the EPA released a final rule under the RFS for renewable fuel volumes for the years 2023-2025 that further increases targets for the production of renewable fuels. Subject to certain limitations, the EPA now has significant discretion to set renewable fuel targets under the RFS, which could result in increased compliance obligations on refiners and importers and transportation fuels.
 The occurrence of any of the events described above could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution to our unitholders.
 We are subject to federal, state and local laws and regulations that govern the product quality specifications of refined petroleum products we purchase, store, transport, and sell to our distribution customers.
 Various federal, state, and local government agencies have the authority to prescribe specific product quality specifications for certain commodities, including commodities that we distribute. Changes in product quality specifications, such as reduced sulfur content in refined petroleum products, or other more stringent requirements for fuels, could reduce our ability to procure product, require us to incur additional handling costs and/or require the expenditure of capital. If we are unable to procure product or recover these costs through increased selling price, we may not be able to meet our financial obligations. Failure to comply with these regulations could result in substantial penalties.
 The swaps regulatory provisions of the Dodd-Frank Act and the rules adopted thereunder could have an adverse effect on our ability to use derivative instruments to mitigate the risks of changes in commodity prices and interest rates and other risks associated with our business.
 Provisions of the Dodd-Frank Act and rules adopted by the Commodity Futures Trading Commission (the "CFTC"), the SEC and other prudential regulators establish federal regulation of the physical and financial derivatives, including over-the-counter derivatives market and entities, such as us, participating in that market. While most of these regulations are already in effect, the implementation process is still ongoing and the CFTC continues to review and refine its initial rulemakings through additional interpretations and supplemental rulemakings. As a result, any new regulations or modifications to existing regulations could

 significantly increase the cost of derivative contracts, materially alter the terms of derivative contracts, reduce the availability and/or liquidity of derivatives to protect against risks we encounter, reduce our ability to monetize or restructure our existing derivative contracts, and increase our exposure to less creditworthy counterparties. Any of these consequences could have a material adverse effect on our financial condition, results of operations and cash available for distribution to our unitholders.
 The CFTC has re-proposed speculative position limits for certain futures and option contracts in the major energy markets and for swaps that are their economic equivalents, although certain bona fide hedging transactions would be exempt from these position limits provided that various conditions are satisfied. The CFTC has also finalized a related aggregation rule that requires market participants to aggregate their positions with certain other persons under common ownership and control, unless an exemption applies, for purposes of determining whether the position limits have been exceeded. If adopted, the revised position limits rule and its finalized companion rule on aggregation may create additional implementation or operational exposure. In addition to the CFTC federal speculative position limit regime, designated contract markets ("DCMs") also maintain speculative position limit and accountability regimes with respect to contracts listed on their platform as well as aggregation requirements similar to the CFTC's final aggregation rule. Any speculative position limit regime, whether imposed at the federal-level or at the DCM-level may impose added operating costs to monitor compliance with such position limit levels, addressing accountability level concerns and maintaining appropriate exemptions, if applicable.
 The Dodd-Frank Act requires that certain classes of swaps be cleared on a derivatives clearing organization and traded on a DCM or other regulated exchange, unless exempt from such clearing and trading requirements, which could result in the application of certain margin requirements imposed by derivatives clearing organizations and their members. The CFTC and prudential regulators have also adopted mandatory margin requirements for uncleared swaps entered into between swap dealers and certain other counterparties. We currently qualify for and rely upon an end-user exception from such clearing and margin requirements for the swaps we enter into to hedge our commercial risks. However, the application of the mandatory clearing and trade execution requirements and the uncleared swaps margin requirements to other market participants, such as swap dealers, may adversely affect the cost and availability of the swaps that we use for hedging.
 In addition to the Dodd-Frank Act, the European Union and other foreign regulators have adopted and are implementing local reforms generally comparable with the reforms under the Dodd-Frank Act. Implementation and enforcement of these regulatory provisions may reduce our ability to hedge our market risks with non-U.S. counterparties and may make transactions involving cross-border swaps more expensive and burdensome. Additionally, the lack of regulatory equivalency across jurisdictions may increase compliance costs and make it more difficult to satisfy our regulatory obligations.
 If third-party pipelines and other facilities interconnected to our fuel storage terminals and transmix processing facilities become partially or fully unavailable to transport refined products, our revenues could be adversely affected.
 We depend upon third-party pipelines and other facilities that provide delivery options to and from our fuel storage terminals and transmix processing facilities. Since we do not own or operate these pipelines or other facilities, their continuing operation in their current manner is not within our control. If any of these third-party facilities become partially or fully unavailable, or if the quality specifications for their facilities change so as to restrict our ability to utilize them, our financial condition and results of operations could be adversely affected.
 The third parties on whom we rely for transportation services to our fuel storage terminals and transmix processing facilities are subject to complex federal, state, and other laws that could adversely affect our financial condition and results of operations.
 The operations of the third parties on whom we rely for transportation services are subject to complex and stringent laws and regulations that require obtaining and maintaining numerous permits, approvals and certifications from various federal, state and local government authorities. These third parties may incur substantial costs in order to comply with existing laws and regulations. If existing laws and regulations governing such third-party services are revised or reinterpreted, or if new laws and regulations become applicable to their operations, these changes may affect the costs that we pay for services. Similarly, a failure to comply with such laws and regulations by the third parties could have a material adverse effect on our financial condition and results of operations.
 Indebtedness
 Our future debt levels may impair our financial condition and our ability to make distributions to our unitholders.
 We had $3.6 billion of debt outstanding as of December 31, 2023. We have the ability to incur additional debt under our Credit Facility and the indentures governing our senior notes. In connection with our merger with NuStar, we expect to assume NuStar's debt and issue additional debt, aggregating approximately $4.2 billion. The level of our future indebtedness could have important consequences to us, including:
 • making it more difficult for us to satisfy our obligations with respect to our senior notes and our credit agreements governing our Credit Facility;

 • limiting our ability to borrow additional amounts to fund working capital, capital expenditures, acquisitions, debt service requirements, the execution of our growth strategy and other activities;
 • requiring us to dedicate a substantial portion of our cash flow from operations to pay interest on our debt, which would reduce our cash flow available to make distributions to our unitholders and to fund working capital, capital expenditures, acquisitions, execution of our growth strategy and other activities;
 • making us more vulnerable to adverse changes in general economic conditions, our industry and government regulations and in our business by limiting our flexibility in planning for, and making it more difficult for us to react quickly to, changing conditions; and
 • placing us at a competitive disadvantage compared with our competitors that have less debt.
 In addition, we may not be able to generate sufficient cash flow from our operations to repay our indebtedness when it becomes due and to meet other cash needs. Our ability to service our debt depends upon, among other things, our financial and operating performance as impacted by prevailing economic conditions, and financial, business, regulatory and other factors, some of which are beyond our control. In addition, our ability to service our debt will depend on market interest rates, since the rates applicable to a portion of our borrowings fluctuate. If we are not able to pay our debts as they become due, we will be required to pursue one or more alternative strategies, such as selling assets, refinancing or restructuring our indebtedness or selling additional debt or equity securities. We may not be able to refinance our debt or sell additional debt or equity securities or our assets on favorable terms, if at all, and if we must sell our assets, it may negatively affect our ability to generate revenues.
 Increases in interest rates could reduce the amount of cash we have available for distributions as well as the relative value of those distributions to yield-oriented investors, which could cause a decline in the market value of our common units.
 Approximately $411 million of our outstanding indebtedness as of December 31, 2023 bears interest at variable interest rates. Should variable interest rates rise, the amount of cash we would otherwise have available for distribution would ordinarily be expected to decline, which could impact our ability to maintain or grow our quarterly distributions. Additionally, an increase in interest rates in lower risk investment alternatives, such as United States treasury securities, could cause investors to demand a relatively higher distribution yield on our common units, which, unless we are able to raise our distribution, would imply a lower trading price for our common units. Consequently, rising interest rates could cause a significant decline in the market value of our common units.
 Our existing debt agreements have substantial restrictions and financial covenants that may restrict our business and financing activities and our ability to pay distributions to our unitholders.
 We are dependent upon the earnings and cash flow generated by our operations in order to meet our debt service obligations and to allow us to make cash distributions to our unitholders. The operating and financial restrictions and covenants in our credit agreement, the indentures governing our senior notes and any future financing agreements may restrict our ability to finance future operations or capital needs, to engage in or expand our business activities or to pay distributions to our unitholders. For example, our credit agreement and the indentures governing our senior notes restrict our ability to, among other things:
 • incur certain additional indebtedness;
 • incur, permit, or assume certain liens to exist on our properties or assets;
 • make certain investments or enter into certain restrictive material contracts;
 • repurchase units; and
 • merge or dispose of all or substantially all of our assets.
 In addition, our credit agreement contains covenants requiring us to maintain certain financial ratios. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" for additional information.
 Our future ability to comply with these restrictions and covenants is uncertain and will be affected by the levels of cash flow from our operations and other events or circumstances beyond our control. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. If we violate any provisions of our credit agreement or the indentures governing our senior notes that are not cured or waived within the appropriate time period provided therein, a significant portion of our indebtedness may become immediately due and payable, our ability to make distributions to our unitholders will be inhibited and our lenders' commitment to make further loans to us may terminate. We might not have, or be able to obtain, sufficient funds to make these accelerated payments.

 Detail of Risk Factors Related to Our Structure
 Our General Partner
 Energy Transfer owns and controls our General Partner, which has sole responsibility for conducting our business and managing our operations. Our General Partner and its affiliates, including Energy Transfer, have conflicts of interest with us and limited contractual duties and they may favor their own interests to the detriment of us and our unitholders.
 Energy Transfer owns and controls our General Partner and appoints all of the officers and directors of our General Partner. Although our General Partner has a contractual obligation to manage us in a manner it believes is not adverse to us, the executive officers and directors of our General Partner also have a contractual duty to manage our General Partner in a manner beneficial to Energy Transfer. Therefore, conflicts of interest may arise between Energy Transfer and its affiliates, including our General Partner, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts of interest, our General Partner may favor its own interests and the interests of its affiliates over the interests of our common unitholders. These conflicts include the following situations, among others:
 • Our General Partner's affiliates, including Energy Transfer and its affiliates, are not prohibited from engaging in other business or activities, including those in direct competition with us.
 • In addition, neither our partnership agreement nor any other agreement requires Energy Transfer to pursue a business strategy that favors us. The affiliates of our General Partner have contractual duties to make decisions in their own best interests and in the best interest of their owners, which may be contrary to our interests. In addition, our General Partner is allowed to take into account the interests of parties other than us or our unitholders, such as Energy Transfer, in resolving conflicts of interest.
 • Certain officers and directors of our General Partner are officers or directors of affiliates of our General Partner, and also devote significant time to the business of these entities and are compensated accordingly.
 • Affiliates of our General Partner, including Energy Transfer, are not limited in their ability to compete with us and may offer business opportunities or sell assets to parties other than us.
 • Our partnership agreement provides that our General Partner may, but is not required to, in connection with its resolution of a conflict of interest, seek "special approval" of such resolution by appointing a conflicts committee of the General Partner's board of directors composed of one or more independent directors to consider such conflicts of interest and to either, itself, take action or recommend action to the board of directors, and any resolution of the conflict of interest by the conflicts committee shall be conclusively deemed to be approved by our unitholders.
 • Except in limited circumstances, our General Partner has the power and authority to conduct our business without unitholder approval.
 • Our General Partner determines the amount and timing of asset purchases and sales, borrowings, repayment of indebtedness and issuances of additional partnership securities and the level of reserves, each of which can affect the amount of cash that is distributed to our unitholders.
 • Our General Partner determines the amount and timing of any capital expenditure and whether a capital expenditure is classified as a maintenance capital expenditure or an expansion capital expenditure. These determinations can affect the amount of cash that is distributed to our unitholders.
 • Our General Partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the purpose or effect of the borrowing is to make incentive distributions on the IDRs.
 • Our partnership agreement permits us to distribute up to $25 million as operating surplus, even if it is generated from asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions on the IDRs.
 • Our General Partner determines which costs incurred by it and its affiliates are reimbursable by us.
 • Our partnership agreement does not restrict our General Partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with its affiliates on our behalf. There is no limitation on the amounts our General Partner can cause us to pay it or its affiliates.
 • Our General Partner has limited its liability regarding our contractual and other obligations.
 • Our General Partner may exercise its right to call and purchase common units if it and its affiliates own more than 80% of the common units.
 • Our General Partner controls the enforcement of obligations owed to us by it and its affiliates. In addition, our General Partner will decide whether to retain separate counsel or others to perform services for us.
 • Energy Transfer may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to Energy Transfer's IDRs without the approval of the conflicts committee of the board of directors of our General Partner or our unitholders. This election may result in lower distributions to our common unitholders in certain situations.

 Our General Partner has limited its liability regarding our obligations.
 Our General Partner has limited its liability under contractual arrangements so that the counterparties to such arrangements have recourse only against our assets, and not against our General Partner or its assets. Our General Partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our General Partner. Our partnership agreement provides that any action taken by our General Partner to limit its liability is not a breach of our General Partner's contractual duties to us, even if we could have obtained more favorable terms without the limitation on liability. In addition, we are obligated to reimburse or indemnify our General Partner to the extent that it incurs obligations on our behalf. Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our unitholders.
 Our General Partner may, in its sole discretion, approve the issuance of partnership securities and specify the terms of such partnership securities.
 Pursuant to our partnership agreement, our General Partner has the ability, in its sole discretion and without the approval of our unitholders, to approve the issuance of securities by the Partnership at any time and to specify the terms and conditions of such securities. The securities authorized to be issued may be issued in one or more classes or series, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of partnership securities), as shall be determined by our General Partner, including:
 • the right to share in the Partnership's profits and losses;
 • the right to share in the Partnership's distributions;
 • the rights upon dissolution and liquidation of the Partnership;
 • whether, and the terms upon which, the Partnership may redeem the securities;
 • whether the securities will be issued, evidenced by certificates and assigned or transferred; and
 • the right, if any, of the security to vote on matters relating to the Partnership, including matters relating to the relative rights, preferences and privileges of such security.
 Cost reimbursements due to our General Partner and its affiliates for services provided to us or on our behalf will reduce cash available for distribution to our unitholders. The amount and timing of such reimbursements will be determined by our General Partner.
 Prior to making any distribution on the common units, we will reimburse our General Partner and its affiliates for all expenses they incur and payments they make on our behalf pursuant to our partnership agreement. Our partnership agreement does not limit the amount of expenses for which our General Partner and its affiliates may be reimbursed. Our partnership agreement provides that our General Partner will determine in good faith the expenses that are allocable to us. Reimbursement of expenses and payment of fees to our General Partner and its affiliates will reduce the amount of cash available to pay distributions to our unitholders.
 Our Partnership Agreement
 Our partnership agreement requires that we distribute all of our available cash, which could limit our ability to grow and make acquisitions.
 Our partnership agreement requires that we distribute all of our available cash to our unitholders. Our General Partner will determine the amount and timing of such distributions and has broad discretion to establish and make additions to our reserves in amounts it determines in its reasonable discretion to be necessary or appropriate. As such, we rely primarily upon external financing sources, including borrowings under our Credit Facility and the issuance of debt and equity securities, to fund our acquisitions and expansion capital requirements. To the extent we are unable to finance growth externally, our cash distribution policy may significantly impair our ability to grow.
 In addition, because we distribute all of our available cash, our growth rate may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement on our ability to issue additional units, including units ranking senior to existing common units. The incurrence of bank borrowings or other debt to finance our growth strategy may result in increased interest expense, which, in turn, may impact the available cash that we have to distribute to our unitholders.

 Our partnership agreement limits the liability and duties of our General Partner and restricts the remedies available to us and our common unitholders for actions taken by our General Partner that might otherwise constitute breaches of fiduciary duty if we were a Delaware corporation.
 Our partnership agreement limits the liability and duties of our General Partner, while also restricting the remedies available to our common unitholders for actions that, without these limitations, might constitute breaches of fiduciary duty under Delaware law. Delaware partnership law permits such contractual reductions or elimination of fiduciary duty. By purchasing common units, common unitholders consent to be bound by the partnership agreement, and pursuant to our partnership agreement, each unitholder consents to various actions and conflicts of interest contemplated in our partnership agreement that might otherwise constitute a breach of fiduciary or other duties under Delaware law. For example:
 • Our partnership agreement permits our General Partner to make a number of decisions in its individual capacity, as opposed to its capacity as General Partner. This entitles our General Partner to consider only the interests and factors that it desires, with no duty or obligation to give consideration to the interests of, or factors affecting, our common unitholders. Decisions made by our General Partner in its individual capacity will be made by Energy Transfer, as the owner of our General Partner, and not by the board of directors of our General Partner. Examples of such decisions include:
 whether to exercise limited call rights;
 how to exercise voting rights with respect to any units it owns;
 whether to exercise registration rights; and
 whether to consent to any merger or consolidation, or amendment to our partnership agreement.
 • Our partnership agreement provides that our General Partner will not have any liability to us or our unitholders for decisions made in its capacity as General Partner so long as it acted in good faith as defined in the partnership agreement, meaning it believed that the decisions were not adverse to the interests of our partnership.
 • Our partnership agreement provides that our General Partner and the officers and directors of our General Partner will not be liable for monetary damages to us for any acts or omissions unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that our General Partner or those persons acted in bad faith or, in the case of a criminal matter, acted with knowledge that such person's conduct was criminal.
 • Our partnership agreement provides that our General Partner will not be in breach of its obligations under the partnership agreement or its duties to us or our limited partners with respect to any transaction involving an affiliate if:
 the transaction with an affiliate or the resolution of a conflict of interest is:
 • approved by the conflicts committee of the board of directors of our General Partner, although our General Partner is not obligated to seek such approval; or
 • approved by the vote of a majority of the outstanding common units, excluding any common units owned by our General Partner and its affiliates; or
 • the board of directors of our General Partner acted in good faith in taking any action or failing to act.
 If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee then it will be presumed that, in making its decision, taking any action or failing to act, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.
 Energy Transfer may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to its IDRs, without the approval of the conflicts committee of our General Partner's board of directors or the holders of our common units. This could result in lower distributions to holders of our common units.
 Energy Transfer has the right, at any time it has received incentive distributions at the highest level to which it is entitled (50%) for each of the prior four consecutive whole fiscal quarters (and the amount of each such did not exceed adjusted operating surplus for each such quarter), to reset the initial target distribution levels at higher levels based on our cash distributions at the time of the exercise of the reset election. Following a reset election by Energy Transfer, the minimum quarterly distribution will be adjusted to equal the reset minimum quarterly distribution, and the target distribution levels will be reset to correspondingly higher levels based on the same percentage increases above the reset minimum quarterly distribution reflected by the current target distribution levels.
 If Energy Transfer elects to reset the target distribution levels, it will be entitled to receive a number of common units equal the number of common units which would have entitled their holder to an average aggregate quarterly cash distribution in the prior two quarters equal to the average of the distributions to Energy Transfer on the IDRs in the prior two quarters. We anticipate that Energy Transfer would exercise this reset right in order to facilitate acquisitions or internal growth projects that would not be sufficiently

 accretive to cash distributions per common unit without such conversion. It is possible, however, that Energy Transfer could exercise this reset election at a time when it is experiencing, or expects to experience, declines in the cash distributions it receives related to its IDRs and may, therefore, desire to be issued common units rather than retain the right to receive incentive distributions based on the initial target distribution levels. As a result, a reset election may cause our common unitholders to experience a reduction in the amount of cash distributions that they would have otherwise received had we not issued new common units to Energy Transfer in connection with resetting the target distribution levels.
 Holders of our common units have limited voting rights and are not entitled to elect our General Partner or its directors.
 Unlike the holders of common stock in a corporation, our common unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management's decisions regarding our business. Our common unitholders have no right on an annual or ongoing basis to elect our General Partner or its board of directors. The board of directors of our General Partner, including the independent directors, are chosen entirely by Energy Transfer due to its ownership of our General Partner, and not by our common unitholders. Unlike a publicly traded corporation, we do not conduct annual meetings of our unitholders to elect directors or conduct other matters routinely conducted at annual meetings of stockholders of corporations. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting our unitholders' ability to influence the manner or direction of management.
 Even if holders of our common units are dissatisfied, they cannot easily remove our General Partner without its consent.
 If our unitholders are dissatisfied with the performance of our General Partner, they have limited ability to remove our General Partner. Our General Partner generally may not be removed except upon the vote of the holders of 66 % of our outstanding common units, including units owned by our General Partner and its affiliates. As of December 31, 2023, Energy Transfer and its affiliates held approximately 33.7% of our outstanding common units, which constitutes a 28.2% limited partner interest in us.
 Our General Partner interest or the control of our General Partner may be transferred to a third party without unitholder consent.
 Our General Partner may transfer its General Partner interest to a third party without the consent of our unitholders in a merger, in a sale of all or substantially all of its assets or in other transactions so long as certain conditions are satisfied. Furthermore, our partnership agreement does not restrict the ability of Energy Transfer to transfer all or a portion of its interest in our General Partner to a third party. Any new owner of our General Partner or our General Partner interest would then be in a position to replace the board of directors and executive officers of our General Partner with its own designees without the consent of unitholders and thereby exert significant control over us, and may change our business strategy.
 Our General Partner has a limited call right that may require unitholders to sell their common units at an undesirable time or price.
 If at any time our General Partner and its affiliates own more than 80% of the common units, our General Partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price equal to the greater of (1) the average of the daily closing price of the common units over the 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (2) the highest per-unit price paid by our General Partner or any of its affiliates for common units during the 90-day period preceding the date such notice is first mailed. As a result, unitholders may be required to sell their common units at an undesirable time or price and may not receive any return or a negative return on their investment. Unitholders may also incur a tax liability upon a sale of their units. Our General Partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the limited call right. There is no restriction in our partnership agreement that prevents our General Partner from issuing additional common units and exercising its call right.
 We may issue additional units without unitholder approval, which would dilute existing unitholder ownership interests.
 Our partnership agreement does not limit the number of additional limited partner interests we may issue at any time without the approval of our unitholders. The issuance of additional common units or other equity interests of equal or senior rank will have the following effects:
 • our existing unitholders' proportionate ownership interest in us will decrease;
 • the amount of cash available for distribution on each unit may decrease;
 • the ratio of taxable income to distributions may increase;
 • the relative voting strength of each previously outstanding unit may be diminished; and
 • the market price of the common units may decline.

 The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public or private markets, including sales by Energy Transfer.
 As of December 31, 2023, Energy Transfer owned 28,463,967 of our common units. The sale or disposition of a substantial portion of these units in the public or private markets could reduce the market price of our outstanding common units.
 Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our outstanding common units.
 Our partnership agreement restricts unitholders' voting rights by providing that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than our General Partner and its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors of our General Partner, cannot vote on any matter.
 The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.
 The amount of cash we have available for distribution depends primarily upon our cash flow, including cash flow from working capital or other borrowings, and not solely on profitability, which will be affected by non-cash items. As a result, we may pay cash distributions during periods when we record net losses for financial accounting purposes and may not pay cash distributions during periods when we record net income.
 Unitholders may have liability to repay distributions.
 Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act (the "Delaware Act"), we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. A purchaser of units who becomes a limited partner is liable for the obligations of the transferring limited partner to make contributions to the partnership that are known to such purchaser at the time it became a limited partner and for unknown obligations if the liabilities could be determined from the partnership agreement. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.
 Our partnership agreement limits the forum, venue and jurisdiction of claims, suits, actions or proceedings.
 Our partnership agreement is governed by Delaware law. Our partnership agreement requires that any claims, suits, actions or proceedings:
 • arising out of or relating in any way to our partnership agreement (including any claims, suits or actions to interpret, apply or enforce the provisions of our partnership agreement or the duties, obligations or liabilities among our limited partners or of our limited partners to us, or the rights or powers of, or restrictions on, our limited partners or us);
 • brought in a derivative manner on our behalf;
 • asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of us or our General Partner, or owed by our General Partner, to us or the limited partners;
 • asserting a claim arising pursuant to any provision of the Delaware Act; or
 • asserting a claim governed by the internal affairs doctrine,
 will be exclusively brought in the Court of Chancery of the State of Delaware (or, if such court does not have subject matter jurisdiction thereof, any other court located in the State of Delaware with subject matter jurisdiction). By purchasing a common unit, a limited partner is irrevocably consenting to these limitations and provisions regarding claims, suits, actions or proceedings and submitting to the exclusive jurisdiction of the Court of Chancery of the State of Delaware in connection with any such claims, suits, actions or proceedings.
 The provisions may have the effect of discouraging lawsuits against our directors, officers, employees and agents. The enforceability of similar forum selection provisions in other companies' certificates of incorporation or similar governing documents have been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could find that the forum selection provision contained in our partnership agreement is inapplicable or unenforceable in such action or actions, including with respect to claims arising under the federal securities laws. Limited partners will not be deemed, by operation of the forum selection provision alone, to have waived claims arising under the federal securities laws and the rules and regulations thereunder.
 The forum selection provision is intended to apply "to the fullest extent permitted by applicable law" to the above-specified types of actions and proceedings, including, to the extent permitted by the federal securities laws, to lawsuits asserting both the above-specified claims and federal securities claims. However, application of the forum selection provision may in some instances be limited

 by applicable law. Section 27 of the Exchange Act provides: "The district courts of the United States... shall have exclusive jurisdiction of violations of the Exchange Act or the rules and regulations thereunder, and of all suits in equity and actions at law brought to enforce any liability or duty created by the Exchange Act or the rules and regulations thereunder." As a result, the forum selection provision will not apply to actions arising under the Exchange Act or the rules and regulations thereunder. However, Section 22 of the Securities Act of 1933, as amended (the "Securities Act") provides for concurrent federal and state court jurisdiction over actions under the Securities Act and the rules and regulations thereunder, subject to a limited exception for certain "covered class actions" as defined in Section 16 of the Securities Act and interpreted by the courts. Accordingly, we believe that the forum selection provision would apply to actions arising under the Securities Act or the rules and regulations thereunder, except to the extent a particular action fell within the exception for covered class actions.
 The NYSE does not require a publicly traded partnership like us to comply with certain corporate governance requirements.
 Because we are a publicly traded partnership, the NYSE does not require us to have a majority of independent directors on our General Partner's board of directors or to establish a compensation committee or a nominating and corporate governance committee. Accordingly, unitholders do not have the same protections afforded to stockholders of corporations that are subject to all of the corporate governance requirements of the applicable stock exchange.
 Detail of Tax Risks to Common Unitholders
 Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service ("IRS") were to treat us as a corporation for U.S. federal income tax purposes or we were otherwise subject to a material amount of entity-level taxation, then our cash available for distribution to our unitholders would be substantially reduced.
 The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for U.S. federal income tax purposes.
 Despite the fact that we are organized as a limited partnership under Delaware law, we will be treated as a corporation for U.S. federal income tax purposes unless we satisfy a "qualifying income" requirement. Based upon our current operations, we believe we satisfy the qualifying income requirement and will continue to satisfy the qualifying income requirement after the acquisition of NuStar. However, no ruling has been or will be requested regarding our treatment as a partnership for U.S. federal income tax purposes. Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity.
 If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate, which is currently a maximum of 21%, and would likely pay state income tax at varying rates. Distributions to our unitholders who are treated as holders of corporate stock would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced.
 Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us.
 In addition, changes in current state law may subject us to additional entity-level taxation by individual states. Several states are evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise and other forms of taxation. For example, we are currently subject to the entity-level Texas franchise tax. Imposition of any such additional taxes on us or an increase in the existing tax rates would reduce the cash available for distribution to our unitholders. Therefore, if we were treated as a corporation for U.S. federal income tax purposes or otherwise subjected to a material amount of entity-level taxation, there would be a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.
 The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.
 The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. Members of Congress have frequently proposed and considered substantive changes to the existing U.S. federal income tax laws that would affect publicly traded partnerships, including proposals that would eliminate our ability to qualify for partnership tax treatment. Recent proposals have provided for the expansion of the qualifying income exception for publicly traded partnerships in certain circumstances and other proposals have provided for the total elimination of the qualifying income exception upon which we rely for our partnership tax treatment.

 In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department's interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the future.
 Any modification to the U.S. federal income tax laws and interpretations thereof may or may not be retroactively applied and could make it more difficult or impossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes. We are unable to predict whether any changes or other proposals will ultimately be enacted. Any future legislative changes could negatively impact the value of an investment in our common units.
 If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collect directly from us taxes (including any applicable penalties and interest) resulting from such audit adjustments, in which case our cash available for distribution to our unitholders might be substantially reduced.
 Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us. To the extent possible under these rules, our General Partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue an information statement to our current and former unitholders with respect to an audited and adjusted return. Although our General Partner may elect to have our current and former unitholders take such audit adjustment into account in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties and interest, our cash available for distribution to our unitholders might be substantially reduced.
 We have subsidiaries that are treated as corporations for U.S. federal income tax purposes and are subject to corporate-level income taxes.
 Even though we (as a partnership for U.S. federal income tax purposes) are not subject to U.S. federal income tax, some of our operations are currently conducted through subsidiaries that are organized as corporations for U.S. federal income tax purposes. The taxable income, if any, of these subsidiaries is subject to corporate-level U.S. federal income taxes, which may reduce the cash available for distribution to us and, in turn, to our unitholders. If the IRS or other state or local jurisdictions were to successfully assert that these corporations have more tax liability than we anticipate or legislation is enacted that increases the corporate tax rate, then cash available for distribution could be further reduced. The income tax return filing positions taken by these corporate subsidiaries requires significant judgment, use of estimates, and the interpretation and application of complex tax laws. Significant judgment is also required in assessing the amounts of deductible and taxable items. Despite our belief that the income tax return positions taken by these subsidiaries are fully supportable, certain positions may be successfully challenged by the IRS, state or local jurisdictions.
 Our unitholders will be required to pay taxes on their share of our income even if they do not receive any cash distributions from us.
 Because our unitholders will be treated as partners to whom we will allocate taxable income that could be different in amount than the cash we distribute, our unitholders will be required to pay U.S. federal income taxes and, in some cases, state and local income taxes on their share of our taxable income whether or not they receive cash distributions from us. Our unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax liability that results from that income.
 Tax gain or loss on the disposition of our common units could be more or less than expected.
 If a unitholder sells its common units, it will recognize a gain or loss equal to the difference between the amount realized and its tax basis in those common units. Because distributions in excess of a unitholder's allocable share of our net taxable income result in a decrease in its tax basis in its common units, the amount, if any, of such prior excess distributions with respect to the common units it sells will, in effect, become taxable income to the unitholder if it sells such common units at a price greater than its tax basis in those common units, even if the price the unitholder receives is less than its original cost. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if a unitholder sells its common units, such unitholder may incur a tax liability in excess of the amount of cash received from the sale.
 Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture of depreciation deductions and certain other items. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if a unitholder sells its common units, the unitholder may incur a tax liability in excess of the amount of cash it receives from the sale.

 Tax-exempt entities face unique tax issues from owning common units that may result in adverse tax consequences to them.
 Investments in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts ("IRAs") raise issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Additionally, all or part of any gain recognized by such tax-exempt organization upon a sale or other disposition of our units may be unrelated business taxable income. Tax-exempt entities should consult a tax advisor before investing in our common units.
 If the IRS contests the U.S. federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contest will reduce our cash available for distribution to our unitholders.
 The IRS may adopt positions that differ from the positions we take, and the IRS's positions may ultimately be sustained. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest by the IRS may materially and adversely impact the market for our common units and the price at which they trade. The costs of any contest by the IRS will be borne indirectly by our unitholders because the costs will reduce our cash available for distribution.
 We treat each purchaser of our common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.
 Because we cannot match transferors and transferees of common units, we have adopted certain methods for allocating depreciation and amortization deductions that may not conform to all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to a unitholder. It also could affect the timing of these tax benefits or the amount of gain from a unitholder's sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to a unitholder's tax returns.
 We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our common units each month based upon the ownership of our common units on the first day of each month, instead of on the basis of the date a particular common unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.
 We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our common units each month based upon the ownership of our common units on the first day of each month (the "Allocation Date"), instead of on the basis of the date a particular common unit is transferred. Similarly, we generally allocate certain deductions for depreciation of capital additions, gain or loss realized on a sale or other disposition of our assets and, in the discretion of the General Partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. Treasury regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of the proration method we have currently adopted. If the IRS were to successfully challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.
 A unitholder whose common units are the subject of a securities loan (e.g., a loan to a "short seller" to cover a short sale of common units) may be considered as having disposed of those common units. If so, the unitholder would no longer be treated for U.S. federal income tax purposes as a partner with respect to those common units during the period of the loan and may recognize gain or loss from the disposition.
 Because there are no specific rules governing the U.S. federal income tax consequence of loaning a partnership interest, a unitholder whose common units are the subject of a securities loan may be considered as having disposed of the loaned common units. In that case, he may no longer be treated for U.S. federal income tax purposes as a partner with respect to those common units during the period of the loan and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities loan are urged to consult a tax advisor to discuss whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their common units.
 We have adopted certain valuation methodologies in determining a unitholder's allocations of income, gain, loss and deduction. The IRS may challenge these methods or the resulting allocations, and such a challenge could adversely affect the value of our common units.
 In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our respective assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we make many fair market value estimates using a methodology based on the market value of our common units as a means to measure the fair market value of our respective assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.

 A successful IRS challenge to these methods or allocations could adversely affect the amount, character, and timing of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain from our unitholders' sale of common units and could have a negative impact on the value of the common units or result in audit adjustments to our unitholders' tax returns without the benefit of additional deductions.
 Unitholders will likely be subject to state and local taxes and return filing requirements in states where they do not live as a result of investing in our common units.
 In addition to U.S. federal income taxes, unitholders may be subject to other taxes, including state and local income taxes, unincorporated business taxes, and estate, inheritance or intangibles taxes that may be imposed by the various jurisdictions in which we conduct business or own property now or in the future or in which the unitholder is a resident. We currently own property or do business in a substantial number of states, most of which impose a personal income tax and many of which impose an income tax on corporations and other entities. We may also own property or do business in other states in the future. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on its investment in us.
 Although you may not be required to file a return and pay taxes in some jurisdictions because your income from that jurisdiction falls below the filing and payment requirement, you will be required to file income tax returns and to pay income taxes in many of the jurisdictions in which we do business or own property and may be subject to penalties for failure to comply with those requirements. Some of the jurisdictions may require us, or we may elect, to withhold a percentage of income from amounts to be distributed to a unitholder who is not a resident of the jurisdiction. Withholding, the amount of which may be greater or less than a particular unitholder's income tax liability to the jurisdiction, generally does not relieve a nonresident unitholder from the obligation to file an income tax return.
 It is the responsibility of each unitholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, of its investment in us. We strongly recommend that each prospective unitholder consult, and depend on, its own tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each unitholder to file all state, local, and non-U.S., as well as U.S. federal tax returns that may be required of it.
 Unitholders may be subject to limitations on their ability to deduct interest expense we incur.
 In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, our deduction for "business interest" is limited to the sum of our business interest income and 30% of our "adjusted taxable income." For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income.
 If our "business interest" is subject to limitation under these rules, our unitholders will be limited in their ability to deduct their share of any interest expense that has been allocated to them. As a result, unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.
 Non-U.S. unitholders will be subject to U.S. federal income taxes and withholding with respect to their income and gain from owning our common units.
 Non-U.S. unitholders are generally taxed and subject to U.S. federal income tax filing requirements on income effectively connected with a U.S. trade or business. Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be "effectively connected" with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate and a non-U.S. unitholder who sells or otherwise disposes of a common unit will also be subject to U.S. federal income tax on the gain realized from the sale or disposition of that unit. In addition to the withholding tax imposed on distributions of effectively connected income, distributions to a non-U.S. unitholder will also be subject to a 10% withholding tax on the amount of any distribution in excess of our cumulative net income. As we do not compute our cumulative net income for such purposes due to the complexity of the calculation and lack of clarity in how it would apply to us, we intend to treat all of our distributions as being in excess of our cumulative net income for such purposes and subject to such 10% withholding tax. Accordingly, distributions to a non-U.S. unitholder will be subject to a combined withholding tax rate equal to the sum of the highest applicable effective tax rate and 10%.
 Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the "amount realized" by the transferor unless the transferor certifies that it is not a foreign person. While the determination of a partner's "amount realized" generally includes any decrease of a partner's share of the partnership's liabilities, the Treasury regulations provide that the "amount realized" on a transfer of an interest in a publicly traded partnership, such as our common units, will generally be the amount of gross proceeds paid to the broker effecting the applicable transfer on behalf of the transferor, and thus will be determined without regard to any decrease in that partner's share of a publicly traded partnership's liabilities. For a transfer of interests in a publicly traded partnership that is effected through a broker on or after January 1, 2023, the obligation to withhold is imposed on the transferor's broker. Current and prospective non-U.S. unitholders should consult their tax advisors regarding the impact of these rules on an investment in our common units.

 Item 1C. Cybersecurity
 Description of Processes for Assessing, Identifying, and Managing Cybersecurity Risks
 The information and operational technology infrastructure we use is important to the operation of our business and to our ability to perform day-to-day operations. In the normal course of business, we may collect and store certain sensitive information of the Partnership, including proprietary and confidential business information, trade secrets, intellectual property, sensitive third-party and employee information, and certain personally identifiable information.
 The Partnership maintains a shared services cybersecurity program for assessing, identifying, and managing material risks from cybersecurity threats. This program includes processes that are modeled after the National Institute of Standards and Technology's Cybersecurity Framework and focuses on using business drivers to guide cybersecurity activities. This program is managed by a team of full-time employees, overseen by our Chief Information Officer, that are tasked with conducting our day-to-day information technology ("IT") operations (collectively, the "IT team"). Furthermore, the Partnership considers cybersecurity risks as part of, and has incorporated its cybersecurity program into, the Partnership's overall risk management processes. Through engagement with the guidance of the Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), Transportation Security Administration (TSA) and the U.S. Coast Guard (USCG), we seek to follow industry cybersecurity standards and protect our infrastructure against cyberattacks from domestic and international threats.
 We seek to use a defense-in-depth approach for cybersecurity management, layers of technology, policies, and training at all levels of the enterprise designed to keep the Partnership's assets secure and operational. We use various processes as part of our efforts to maintain the confidentiality, integrity, and availability of our systems, including security threat intelligence, incident response, identity and access management, supply-chain security assessments, endpoint extended detection and response protection, network segmentation, data encryption, event monitoring, and a Security Operations Center (SOC). In an effort to validate the effectiveness of our cybersecurity program and assess such program's compliance with legal and regulatory requirements, we engage third-party service providers to perform audits, assessments, and penetration tests.
 Cybersecurity awareness among our employees is promoted with regular training and awareness programs. All employees who have access to our systems are required to undergo annual cybersecurity training and, each year, our employees must review and acknowledge our cybersecurity policies. Further, our IT team is trained to understand how to manage, use and protect personally identifiable information. User access controls have been implemented to limit unauthorized access to sensitive information and critical systems. Employees are required to use multifactor authentication and keep their passwords confidential, among other measures.
 We recognize that third-party service providers may introduce cybersecurity risks. In an effort to mitigate these risks, before contracting with certain technology services providers, when possible, we conduct due diligence to evaluate their cybersecurity capabilities. Additionally, we endeavor to include cybersecurity requirements in our contracts with these providers and endeavor to require them to adhere to security standards and protocols. Further, we also endeavor to engage with any third-party service providers with access to personally identifiable employee information to evaluate their security controls.
 Finally, the Partnership maintains cybersecurity insurance coverage.
 Impact of Risks from Cybersecurity Threats
 As of the date of this Annual Report on Form 10-K, though the Partnership and our service providers have experienced certain cybersecurity incidents, we are not aware of any previous cybersecurity threats that have materially affected the Partnership, either financially or operationally. Cybersecurity incident response is a component of both the Partnership's cybersecurity program and the Partnership's business continuity plans, which are designed to limit service interruptions and provide for continued business operation in the event of disaster, whether physical, environmental or cyber in nature. However, we recognize that cybersecurity threats are continually evolving, and there remains a risk that a cybersecurity incident could potentially negatively impact the Partnership. Despite the implementation of our cybersecurity processes, we cannot guarantee that a significant cybersecurity attack will not occur. A successful attack on our information system or operational technology system could have significant consequences to the business, including the interruption of key services that our customers depend on. While we devote resources to our security measures to protect our systems and information, these measures cannot provide absolute security. Due to the number of acquisitions made by the Partnership over the past few years and the time it takes to implement technology standards across the enterprise, certain assets may be in different stages of integration and may have incomplete cybersecurity controls applied. For additional information on cybersecurity risks, see "Item 1A. Risk Factors - Cybersecurity attacks, data breaches and other disruptions affecting us, or our service providers, could materially and adversely affect our business, operations, reputation, and financial results; and - We rely on our information

 technology systems to manage numerous aspects of our business, and a disruption of these systems could adversely affect our business."
 Board of Directors' Oversight and Management's Role
 Our Chief Information Officer oversees the Partnership's functions of IT, cybersecurity, infrastructure and IT governance (including the Partnership's IT team) and has more than 35 years of experience leading business technology functions. The Partnership's IT team is responsible for our efforts to comply with applicable cybersecurity standards, establish effective cybersecurity protocols and protect the integrity, confidentiality and availability of our IT infrastructure. The members of this team have over 50 years of combined experience in the field of IT, including 20 years dedicated to cybersecurity, and hold various certifications, including Global Industrial Cyber Security Professional (GICSP), Certified Information Systems Security Professional (CISSP) and Certified Ethical Hacker (CEH) certifications. This team is responsible for cybersecurity threat prevention, detection, mitigation, and remediation for the combined organization. Our cyber incident response plan requires IT team members who detect suspicious activity in our IT environment to escalate that activity to a supervisor who then evaluates the threat. If necessary, the suspicious activity is reported to the Chief Information Officer. Management (including representatives from the legal, human resources, IT and corporate security departments) is notified by the IT team whenever a discovered cybersecurity incident may potentially have a significant impact on our business operations.
 The Partnership's Board of Directors has delegated the responsibility for the oversight of cybersecurity risks to the Audit Committee, which is ultimately responsible for assessing and managing the Partnership's material risks from cybersecurity threats. The IT team provides periodic cybersecurity program updates to senior management and to the Audit Committee. Management also updates the Audit Committee as new risks are identified and the steps taken to mitigate such risks.

 Item 2. Properties
 A description of our properties is included in "Item 1. Business." In addition, we own and lease warehouses and offices in Pennsylvania, Texas, Hawaii and Puerto Rico. While we may require additional warehouse and office space as our business expands, we believe that our existing facilities are adequate to meet our needs for the immediate future, and that additional facilities will be available on commercially reasonable terms as needed.
 We believe that we have satisfactory title to or valid rights to use all of our material properties. Although some of our properties are subject to liabilities and leases, liens for taxes not yet due and payable, encumbrances securing payment obligations under non-competition agreements and immaterial encumbrances, easements and restrictions, we do not believe that any such burdens will materially interfere with our continued use of such properties in our business, taken as a whole. In addition, we believe that we have, or are in the process of obtaining, all required material approvals, authorizations, orders, licenses, permits, franchises and consents of, and have obtained or made all required material registrations, qualifications and filings with, the various state and local government and regulatory authorities which relate to ownership of our properties or the operations of our business.

 Item 3. Legal Proceedings
 Although we may, from time to time, be involved in litigation and claims arising out of our operations in the normal course of business, we do not believe that we are party to any litigation that will have a material adverse impact to our financial condition or results of operations.

 Item 4. Mine Safety Disclosures
 Not applicable.

 Item 5. Market for Registrant's Common Equity, Related Unitholder Matters and Issuer Purchases of Equity Securities
 Our Partnership Interest
 As of February 9, 2024, we had outstanding 84,428,109 common units, 16,410,780 Class C units representing limited partner interests in the Partnership ("Class C Units"), a non-economic general partner interest and IDRs. As of February 9, 2024, Energy Transfer directly owned approximately 33.7% of our outstanding common units, which constituted a 28.2% limited partner ownership interest in us. Our General Partner is 100% owned by Energy Transfer and owns a non-economic general partner interest in us. Energy Transfer also owns all of our IDRs. As discussed below, the IDRs represent the right to receive increasing percentages, up to a maximum of 50%, of the cash we distribute from operating surplus (as defined below) in excess of $0.503125 per unit per quarter. Our common units, which represent limited partner interests in us, are listed on the NYSE under the symbol "SUN." Our common units have been traded on the NYSE since September 20, 2012.
 Holders
 At the close of business on February 9, 2024, we had 21 holders of record of our common units and two holders of record of our Class C Units. The number of record holders does not include holders of units in "street names" or persons, partnerships, associations, corporations or other entities identified in security position listings maintained by depositories.
 Distributions of Available Cash
 Our partnership agreement requires that within 60 days after the end of each quarter, we distribute our available cash to unitholders of record on the applicable record date.
 Definition of Available Cash
 Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of the quarter; less, the amount of cash reserves established by our General Partner at the date of determination of available cash for the quarter to:
 • provide for the proper conduct of our business;
 • comply with applicable law, any of our debt instruments or other agreements or any other obligation; or
 • provide funds for distributions to our unitholders for any one or more of the next four quarters;
 plus, if our General Partner so determines on the date of determination, all or any portion of the cash on hand immediately prior to the date of determination of available cash for the quarter, including cash on hand resulting from working capital borrowings made after the end of the quarter.
 Minimum Quarterly Distributions
 We intend to make a cash distribution to the holders of our common units and Class C Units on a quarterly basis to the extent we have sufficient cash from our operations after the establishment of cash reserves and the payment of costs and expenses, including payments to our General Partner and its affiliates. However, there is no guarantee that we will pay the minimum quarterly distribution, as described below, on our common units in any quarter. Even if our cash distribution policy is not modified or revoked, the amount of distributions paid under our policy and the decision to make any distribution is determined by our General Partner, taking into consideration the terms of our partnership agreement.
 Incentive Distribution Rights
 The following table illustrates the percentage allocations of available cash from operating surplus, after the payment of distributions to the Class C unitholders, between our common unitholders and the holder of our IDRs based on the specified target distribution levels. The amounts set forth under "marginal percentage interest in distributions" are the percentage interests of the holder of our IDRs 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 the holder of our IDRs for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. Energy Transfer currently owns all of our IDRs.

 Class C Units
 We have 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 are entitled to receive quarterly distributions at a rate of $0.8682 per Class C Unit. The distributions on the Class C Units are paid out of our available cash, except that the Class C Units do not share in distributions of available cash to the extent such cash is derived from or attributable to any distribution received by us from Sunoco Retail, our indirect wholly owned subsidiary that is subject to state and federal income tax, the proceeds of any sale of the membership interests in Sunoco Retail, or any interest or principal payments we receive with respect to indebtedness of Sunoco Retail or its subsidiaries. The Class C Units are entitled to receive distributions of available cash (other than available cash attributable to Sunoco Retail) prior to distributions of such cash being made on our common units. Any unpaid distributions on the Class C Units will accrue interest at a rate of 1.5% per annum until paid in full in cash. The Class C Units are perpetual, do not have any rights of redemption or conversion, do not have the right to vote on any matter except as otherwise required by any non-waivable provision of law, and are not traded on any public securities market.

 Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
 (Tabular dollar and unit amounts, except per unit data, are in millions)
 The following discussion and analysis of our financial condition and results of operations for the years ended December 31, 2023 and 2022 should be read in conjunction with our audited consolidated financial statements and notes to audited consolidated financial statements included elsewhere in this report. For a discussion and analysis of our financial condition and results of operations for the years ended December 31, 2022 and 2021, please see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in conjunction with our audited consolidated financial statements and notes to audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 17, 2023.
 Adjusted EBITDA is a non-GAAP financial measure of performance that has limitations and should not be considered as a substitute for net income or cash provided by operating activities. Please see "Key Measures Used to Evaluate and Assess Our Business" below for a discussion of our use of Adjusted EBITDA in this "Management's Discussion and Analysis of Financial Condition and Results of Operations" and a reconciliation to net income for the periods presented.
 Overview
 As used in this Management's Discussion and Analysis of Financial Condition and Results of Operations, the terms "Partnership," "SUN," "we," "us" or "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 primarily engaged in the distribution of motor fuels to independent dealers, distributors and other customers as well as the distribution of motor fuels to end-use customers at retail sites operated by commission agents. In addition, we receive lease income through the leasing or subleasing of real estate used in the retail distribution of motor fuels. As of December 31, 2023, we also operated 75 retail stores located in Hawaii and New Jersey.
 We are the exclusive wholesale supplier of the Sunoco and EcoMaxx-branded motor fuels, supplying an extensive distribution network of approximately 5,534 company and third-party operated locations throughout the United States and Puerto Rico. We believe we are one of the largest independent motor fuel distributors, by gallons, in the United States. We also are one of the largest

 distributors of Chevron, Texaco, ExxonMobil and Valero branded motor fuel in the United States. In addition to distributing motor fuel, we also distribute other petroleum products such as propane and lubricating oil.
 We purchase motor fuel primarily from independent refiners and major oil companies and distribute it across more than 40 states and territories throughout the United States, including Hawaii and Puerto Rico, to:
 •75 company-operated retail stores;
 •476 independently operated commission agent locations where we sell motor fuel to retail customers under commission agent arrangement with such operators;
 •6,828 retail stores operated by independent operators, which we refer to as "dealers" or "distributors," pursuant to long-term distribution agreements; and
 • approximately 1,600 other commercial customers, including unbranded retail stores, other fuel distributors, school districts, municipalities and other industrial customers.
 Our retail stores operate under several brands, including our proprietary brands APlus and Aloha Island Mart, and offer a broad selection of food, beverages, snacks, grocery and non-food merchandise, motor fuels and other services.
 Acquisitions
 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.
 On May 1, 2023, the Partnership completed the acquisition of 16 refined product terminals located across the East Coast and Midwest from Zenith Energy for $111 million, including working capital.
 Market and Industry Trends and Outlook
 We expect that certain trends and economic or industry-wide factors will continue to affect our business, both in the short-term and long-term. Inflation has a minimal impact on our results of operations, because we are generally able to pass along energy cost increases in the form of increased sales prices to our customers. We have recently completed and recently announced multiple strategic transactions, which we expect will continue to diversify the Partnership's business, add scale and expand cash for reinvestment and distribution growth. We base our expectations on information currently available to us and assumptions made by us. To the extent our underlying assumptions about or interpretation of available information prove to be incorrect, our actual results may vary materially from our expected results. Read "Item 1A. Risk Factors" included herein for additional information about the risks associated with purchasing our common units.
 Seasonality
 Our business exhibits some seasonality due to our customers' increased demand for motor fuel during the late spring and summer months, as compared to the fall and winter months. Travel, recreation, and construction activities typically increase in these months, driving up the demand for motor fuel sales. Our gallons sold are typically somewhat higher in the second and third quarters of our fiscal years due to this seasonality. Results of operations may therefore vary from period to period.
 Key Measures Used to Evaluate and Assess Our Business
 Management uses a variety of financial measurements to analyze business performance, including the following key measures:
 • Motor fuel gallons sold. One of the primary drivers of our business is the total volume of motor fuel sold through our channels. Fuel distribution contracts with our customers generally provide that we distribute motor fuel at a fixed, volume-

 based profit margin or at an agreed upon level of price support. As a result, profit is directly tied to the volume of motor fuel that we distribute. Total motor fuel profit dollars earned from the product of profit per gallon and motor fuel gallons sold are used by management to evaluate business performance.
 • Profit per gallon. Profit per gallon is calculated as the profit on motor fuel (excluding non-cash inventory adjustments) divided by the number of gallons sold, and is typically expressed as cents per gallon. Our profit per gallon varies amongst our third-party relationships and is impacted by the availability of certain discounts and rebates from suppliers. Retail profit per gallon is heavily impacted by volatile pricing and intense competition from retail stores, supermarkets, club stores and other retail formats, which varies based on the market.
 • Adjusted EBITDA. Adjusted EBITDA, as used throughout this document, is defined as earnings before net interest expense, income taxes, depreciation, amortization and accretion expense, allocated non-cash unit-based compensation expense, 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, such as gain or loss on disposal of assets and non-cash impairment charges. Inventory adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.
 Adjusted EBITDA is a non-GAAP financial measure. For a reconciliation of Adjusted EBITDA to the most directly comparable financial measure calculated and presented in accordance with GAAP, read "Key Operating Metrics and Results of Operations" below.
 We believe Adjusted EBITDA is useful to investors in evaluating our operating performance because:
 • Adjusted EBITDA is used as a performance measure under our Credit Facility;
 • securities analysts and other interested parties use Adjusted EBITDA as a measure of financial performance; and
 • our management uses Adjusted EBITDA for internal planning purposes, including aspects of our consolidated operating budget and capital expenditures.
 Adjusted EBITDA is not a recognized term under GAAP and does not purport to be an alternative to net income as a measure of operating performance. Adjusted EBITDA has limitations as an analytical tool, and one should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations include:
 • it does not reflect interest expense or the cash requirements necessary to service interest or principal payments on our Credit Facility;
 • although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect cash requirements for such replacements; and
 • as not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies.
 Adjusted EBITDA reflects amounts for unconsolidated affiliates based on the same recognition and measurement methods used to record equity in earnings of unconsolidated affiliates. Adjusted EBITDA related to unconsolidated affiliates excludes the same items with respect to the unconsolidated affiliates as those excluded from the calculation of Adjusted EBITDA, such as interest, taxes, depreciation, depletion, amortization and other non-cash items. Although these amounts are excluded from Adjusted EBITDA related to unconsolidated affiliates, such exclusion should not be understood to imply that we have control over the operations and resulting revenues and expenses of such affiliate. We do not control our unconsolidated affiliates; therefore, we do not control the earnings or cash flows of such affiliates. The use of Adjusted EBITDA or Adjusted EBITDA related to unconsolidated affiliates as an analytical tool should be limited accordingly.

 Year Ended December 31, 2023 Compared to Year Ended December 31, 2022
 The following discussion of results compares the operations for the years ended December 31, 2023 and 2022.

 Net Income and Comprehensive Income. Total net income and comprehensive income for 2023 was $394 million, a decrease of $81 million from 2022. The decrease was primarily attributable to the following changes:
 • an increase in interest expense, general and administrative expenses and other operating expense of $59 million in the aggregate. These increases are discussed in more detail below; and
 • a decrease in motor fuel profit of $51 million (including unrealized valuation adjustments), which was primarily due to unfavorable inventory adjustments in the current year (see below for explanation of inventory adjustments), partially offset by an increase in volume; partially offset by
 • an increase in non-motor fuel profit and lease income of $37 million in the aggregate. These items are discussed in more detail below.
 Adjusted EBITDA. Total Adjusted EBITDA for 2023 was $964 million, an increase of $45 million from 2022. The increase was primarily attributable to the following changes:
 • an increase in the profit on motor fuel sales of $34 million, primarily due to an 8.1% increase in gallons sold; and
 • an increase in non-motor fuel profit of $37 million, primarily due to increased throughput and storage margin from the Gladieux and Zenith acquisitions and increased rental income; partially offset by
 • an increase in operating costs of $26 million, including other operating expense, general and administrative expense and lease expense. The increase was primarily due to higher costs as a result of the recent acquisitions of refined product terminals and the transmix processing and terminal facility.
 Interest Expense. Interest expense was $217 million in 2023, an increase of $35 million from 2022. This increase was primarily attributable to higher interest rates on floating rate debt for the respective periods.
 Gain on Disposal of Assets. Gains on disposals of assets reflect the difference between the net book value of disposed assets and the proceeds received upon disposal of those assets. For 2023 and 2022, proceeds from disposal of property and equipment were $31 million and $32 million, respectively.
 Unrealized (Gain) Loss on Commodity Derivatives. The unrealized gains and losses on our commodity derivatives represent the changes in fair value of our commodity derivatives. The change in unrealized gains and losses between periods was impacted by the notional amounts and commodity price changes on our commodity derivatives. Additional information on commodity derivatives is included in "Item 7A. Quantitative and Qualitative Disclosures about Market Risk" below.
 Inventory Adjustments. Inventory adjustments represent changes in lower of cost or market reserves on the Partnership's inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period. For 2023, a decline in fuel prices caused lower of cost or market reserve requirements to increase by $114 million, which reduced net income. For 2022, an increase in fuel prices caused lower of cost or market reserve requirements to decrease by $5 million, which increased net income.
 Income Tax Expense. Income tax expense for 2023 was $36 million, an increase of $10 million from 2022. The increase was primarily attributable to a favorable state rate change in the prior period.

 Liquidity and Capital Resources
 Liquidity
 Our principal liquidity requirements are to finance current operations, to fund capital expenditures, including acquisitions from time to time, to service our debt and to make distributions. We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our Credit Facility and the issuance of additional long-term debt or partnership units as appropriate given market conditions. We expect that these sources of funds will be adequate to provide for our short-term and long-term liquidity needs.
 Our ability to meet our debt service obligations and other capital requirements, including capital expenditures and acquisitions, will depend on our future operating performance which, in turn, will be subject to general economic, financial, business, competitive, legislative, regulatory and other conditions, many of which are beyond our control. As a normal part of our business, depending on market conditions, we will from time to time consider opportunities to repay, redeem, repurchase or refinance our indebtedness. Changes in our operating plans, lower than anticipated sales, increased expenses, acquisitions or other events may cause us to seek additional debt or equity financing in future periods. There can be no guarantee that financing will be available on acceptable terms or at all. Debt financing, if available, could impose additional cash payment obligations and additional covenants and operating restrictions. In addition, any of the items discussed in detail under "Item 1A. Risk Factors" included in this Annual Report on Form 10-K may also significantly impact our liquidity.

 The Partnership is party to 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 line of credit issuer (the "Credit Facility"). As of December 31, 2023, we had $29 million of cash and cash equivalents on hand and borrowing capacity of $1.084 billion under the Credit Facility. Based on our current estimates, we expect to utilize capacity under the Credit Facility, along with cash from operations, to fund our announced growth capital expenditures and working capital needs; however, we may issue debt or equity securities prior to that time as we deem prudent to provide liquidity for new capital projects or other partnership purposes.
 Cash Flows
 Our cash flows may change in the future due to a number of factors, some of which we cannot control. These factors include regulatory changes, the price of products and services, the demand for such products and services, margin requirements resulting from significant changes in commodity prices, operational risks, the successful integration of our acquisitions and other factors.

 Operating Activities
 Changes in cash flows from operating activities between periods primarily result from changes in earnings, excluding the impacts of non-cash items and changes in operating assets and liabilities (net of effects of acquisitions). Non-cash items include recurring non-cash expenses, such as depreciation, depletion and amortization expense and non-cash unit-based compensation expense. Cash flows from operating activities also differ from earnings as a result of non-cash charges that may not be recurring, such as impairment charges. Our daily working capital requirements fluctuate within each month, primarily in response to the timing of payments for motor fuels, motor fuels tax and rent.
 Cash Flows Provided by Operations.
 Net cash provided by operations was $600 million and $561 million, for 2023, and 2022, respectively. The increase in cash flows provided by operations was primarily due to a $26 million net increase in cash basis net income compared to the prior year; partially offset by a decrease in net cash flow from operating assets and liabilities of $13 million compared to the prior year.
 Investing Activities
 Cash flows from investing activities primarily consist of capital expenditures, cash contributions to unconsolidated affiliates, cash amounts paid for acquisitions and cash proceeds from sale or disposal of assets. Changes in capital expenditures between periods primarily result from increases or decreases in our growth capital expenditures to fund our expansion projects.
 Cash Flows Used in Investing Activities.
 Net cash used in investing activities was $288 million and $464 million, for 2023 and 2022, respectively. Net cash used in investing activities included $111 million and $318 million of cash paid for acquisitions in 2023 and 2022, respectively. Capital expenditures were $215 million and $186 million for 2023 and 2022, respectively. Proceeds from disposal of property and equipment were $31 million and $32 million in 2023 and 2022, respectively. Distributions from unconsolidated affiliates in excess of cumulative earnings were $9 million in 2023 and $8 million in 2022.
 Financing Activities
 Changes in cash flows from financing activities between periods primarily result from changes in the levels of borrowings and equity issuances, which are primarily used to fund our acquisitions and growth capital expenditures. Distributions increase between the periods based on increases in the number of common units outstanding or increases in the distribution rate.
 Cash Flows Used in Financing Activities.
 Net cash used in financing activities was $365 million and $40 million for 2023 and 2022, respectively.
 Year Ended December 31, 2023
 During the year ended December 31, 2023 we:
 • issued $500 million of 7.000% senior notes due 2028;

 • borrowed $3.3 billion and repaid $3.8 billion under the Credit Facility to fund daily operations; and
 • paid $371 million in distributions to our unitholders, of which $171 million was paid to Energy Transfer.
 Year Ended December 31, 2022
 During the year ended December 31, 2022 we:
 • borrowed $4.1 billion and repaid $3.8 billion under the Credit Facility to fund daily operations; and
 • paid $359 million in distributions to our unitholders, of which $166 million was paid to Energy Transfer.
 We intend to pay cash distributions to the holders of our common units and Class C Units on a quarterly basis, to the extent we have sufficient cash from our operations after establishment of cash reserves and payment of fees and expenses, including payments to our General Partner and its affiliates. Class C unitholders receive distributions at a fixed rate equal to $0.8682 per quarter for each Class C Unit outstanding. There is no guarantee that we will pay a distribution on our units. On January 25, 2024, we declared a quarterly distribution of $0.8420 per common unit based on the results for the three months ended December 31, 2023, excluding distributions to Class C unitholders. The distribution will be approximately $71 million in the aggregate for common units and approximately $19 million with respect to IDRs, and will be paid on February 20, 2024 to all unitholders of record on February 7, 2024.
 Capital Expenditures
 Included in our capital expenditures for 2023 was $70 million in maintenance capital and $145 million in growth capital. Growth capital relates primarily to dealer and distributor supply contracts and terminals.
 We currently expect to spend approximately $70 million in maintenance capital and at least $200 million in growth capital for the full year 2024.

 Credit Facility
 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 $1.1 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.
 Recent Financing Transaction
 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. The Partnership used the proceeds from the private offering to repay a portion of the outstanding borrowings under the Credit Facility.
 Pending NuStar Acquisition
 In connection with our acquisition of NuStar, we expect to assume NuStar's debt and issue additional debt, aggregating approximately $4.2 billion, subsequent to which the Partnership expects to remain in compliance with all existing financial covenants.

 Contractual Obligations
 We periodically enter into derivatives, such as futures and options, to manage our fuel price risk on inventory in the distribution system. Fuel hedging positions are not significant to our operations. On a consolidated basis, the Partnership had a position of 1.1 million barrels with an aggregated unrealized loss of $8.6 million at December 31, 2023.
 Off-Balance Sheet Arrangements
 We do not maintain any off-balance sheet arrangements for the purpose of credit enhancement, hedging transactions or other financial or investment purposes.
 Critical Accounting Estimates
 We prepare our consolidated financial statements in conformity with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities as of 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.
 Critical accounting policies are those we believe are both most important to the portrayal of our financial condition and results of operations, and require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain. Judgments and uncertainties affecting the application of those policies may result in materially different amounts being reported under different conditions or using different assumptions.
 We believe the following policies will be the most critical in understanding the judgments that are involved in preparation of our consolidated financial statements.
 Fair Value Estimates in Business Combination Accounting and Impairment of Long-Lived Assets, Goodwill, Intangible Assets and Investments in Unconsolidated Affiliates. Business combination accounting and quantitative impairment testing are required from time to time due to the occurrence of events, changes in circumstances, or annual testing requirements. For business combinations, assets and liabilities are required to be recorded at estimated fair value in connection with the initial recognition of the transaction. For impairment testing, long-lived assets are required to be tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Goodwill and intangibles with indefinite lives must be tested for impairment annually or more frequently if events or changes in circumstances indicate that the related asset might be impaired. An impairment of an investment in an unconsolidated affiliate is recognized when circumstances indicate that a decline in the investment value is other than temporary. An impairment loss should be recognized only if the carrying amount of the asset/goodwill is not recoverable and exceeds its fair value. Calculating the fair value of assets or reporting units in connection with business combination accounting or impairment testing requires management to make several estimates, assumptions and judgements, and in some circumstances management may also utilize third-party specialists to assist and advise on those calculations.
 In order to allocate the purchase price in a business combination or to test for recoverability when performing a quantitative impairment test, we must make estimates of projected cash flows related to the asset, which include, but are not limited to, assumptions about the use or disposition of the asset, estimated remaining life of the asset, and future expenditures necessary to maintain the asset's existing service potential. In order to determine fair value, we make certain estimates and assumptions, including, among other things, changes in general economic conditions in regions in which our markets are located, the availability and prices of commodities, our ability to negotiate favorable sales agreements, the risks that exploration and production activities will not occur or be successful, our dependence on certain significant customers and producers, and competition from other companies, including major energy producers. While we believe we have made reasonable assumptions to calculate the fair value, if future results are not consistent with our estimates, we could be exposed to future impairment losses that could be material to our results of operations.
 The Partnership determines the fair value of our reporting units using the discounted cash flow method, the guideline company method, or a weighted combination of these methods. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, operating margins, weighted average costs of capital and future market conditions, among others. 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. Under the discounted cash flow method, the Partnership determines fair value based on estimated future cash flows of each reporting unit including estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflect the overall level of inherent risk of the reporting unit. 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 determines 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 estimates 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.
 One key assumption in these fair value calculations is management's estimate of future cash flows and EBITDA. In accounting for a business combination, these estimates are generally based on the forecasts that were used to analyze the deal economics. For impairment testing, these estimates are based on the annual budget for the upcoming year and forecasted amounts for multiple subsequent years. The annual budget process is typically completed near the annual goodwill impairment testing date, and management uses the most recent information for the annual impairment tests. The forecast is also subjected to a comprehensive update annually in conjunction with the annual budget process and is revised periodically to reflect new information and/or revised expectations. The estimates of future cash flows and EBITDA are subjective in nature and are subject to impacts from the business risks described in "Item 1A. Risk Factors." Therefore, the actual results could differ significantly from the amounts used for business combination accounting and impairment testing, and significant changes in fair value estimates could occur in a given period. Such changes in fair value estimates could result in changes to the fair value estimates used in business combination accounting, which could significantly impact results of operations in a period subsequent to the business combination, depending on multiple factors, including the timing of such changes. In the case of impairment testing, such changes could result in additional impairments in future periods; therefore, the actual results could differ significantly from the amounts used for goodwill impairment testing, and significant changes in fair value estimates could occur in a given period, resulting in additional impairments.
 In addition, we may change our method of impairment testing, including changing the weight assigned to different valuation models. Such changes could be driven by various factors, including the level of precision or availability of data for our assumptions. Any changes in the method of testing could also result in an impairment or impact the magnitude of an impairment.
 Management does not believe that any of the Partnership's goodwill balances, long-lived assets or investments in unconsolidated affiliates is currently at significant risk of a material impairment.
 Income Taxes. As a limited partnership, we are generally not subject to state and federal income tax and would therefore not recognize deferred income tax liabilities and assets for the expected future income tax consequences of temporary differences between financial statement carrying amounts and the related income tax basis. We are, however, subject to a statutory requirement that our non-qualifying income cannot exceed 10% of our total gross income, determined on a calendar year basis under the applicable income tax provisions. If the amount of our non-qualifying income exceeds this statutory limit, we would be taxed as a corporation. Accordingly, certain activities that generate non-qualifying income are conducted through our wholly owned taxable corporate subsidiaries for which we have recognized deferred income tax liabilities and assets. These balances, as well as any income tax expense, are determined through management's estimations, interpretation of tax laws of multiple jurisdictions and tax planning strategies. If our actual results differ from estimated results due to changes in tax laws, our effective tax rate and tax balances could be affected. As such, these estimates may require adjustments in the future as additional facts become known or as circumstances change.
 The benefit of an uncertain tax position can only be recognized in the consolidated financial statements if management concludes that it is more likely than not that the position will be sustained with the tax authorities. For a position that is likely to be sustained, the benefit recognized in the consolidated financial statements is measured at the largest amount that is greater than 50% likely of being realized. In determining the future tax consequences of events that have been recognized in our consolidated financial statements or tax returns, judgment is required. Differences between the anticipated and actual outcomes of these future tax consequences could have a material impact on our consolidated results of operations or financial position.

 Item 7A. Quantitative and Qualitative Disclosures about Market Risk
 Interest Rate Risk
 We are subject to market risk from exposure to changes in interest rates based on our financing, investing and cash management activities. We had outstanding variable interest rate borrowings on the Credit Facility of $411 million as of December 31, 2023. A hypothetical change of 100 basis points would result in a maximum potential change to interest expense of $4 million annually. Our primary exposure relates to:
 • interest rate risk on short-term borrowings; and
 • the impact of interest rate movements on our ability to obtain adequate financing to fund future acquisitions.
 While we cannot predict or manage our ability to refinance existing debt or the impact interest rate movements will have on our existing debt, management evaluates our financial position on an ongoing basis. From time to time, we may enter into interest rate swaps to reduce the impact of changes in interest rates on our floating rate debt. We had no interest rate swaps in effect during the years ended December 31, 2023 and 2022.

 Commodity Price Risk
 Our subsidiaries hold working inventories of refined petroleum products, renewable fuels, gasoline blendstocks and transmix in storage. As of December 31, 2023, we held approximately $812 million of such inventory. While in storage, volatility in the market price of stored motor fuel could adversely impact the price at which we can later sell the motor fuel. However, we may use futures, forwards and other derivative instruments (collectively, "positions") to hedge a variety of price risks relating to deviations in that inventory from a target base operating level established by management. Derivative instruments utilized consist primarily of exchange-traded futures contracts traded on the New York Mercantile Exchange, Chicago Mercantile Exchange and Intercontinental Exchange, as well as over-the-counter transactions (including swap agreements) entered into with established financial institutions and other credit-approved energy companies. Our policy is generally to purchase only products for which there is a market and to structure sales contracts so that price fluctuations do not materially affect profit. While these derivative instruments represent economic hedges, they are not designated as hedges for accounting purposes. We may also engage in controlled trading in accordance with specific parameters set forth in a written risk management policy.
 On a consolidated basis, the Partnership had a position of 1.1 million barrels with an aggregated unrealized gain of $8.6 million at December 31, 2023.

 Item 9A. Controls and Procedures
 Disclosure Controls and Procedures
 We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act), that are designed to provide reasonable assurance that the information that we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. It should be noted that, because of inherent limitations, our disclosure controls and procedures, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the disclosure controls and procedures are met.
 As required by paragraph (b) of Rule 13a-15 under the Exchange Act, our management with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Form 10-K. Based on such evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, has concluded, as of December 31, 2023, that our disclosure controls and procedures were effective at the reasonable assurance level for which they were designed in that the information required to be disclosed by the Partnership in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.
 Management's Report on Internal Control over Financial Reporting
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process that is designed under the supervision of our Chief Executive Officer and Chief Financial Officer and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Our internal control over financial reporting includes those policies and procedures that:
 • pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;
 • provide reasonable assurance that transactions are recorded as necessary to permit preparation of our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures recorded by us are being made only in accordance with authorizations of our management and board of directors; and

 • provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements.
 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.
 Management conducted its evaluation of the effectiveness of internal control over financial reporting as of December 31, 2023, based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management's assessment included an evaluation of the design of its internal control over financial reporting and testing the operational effectiveness of its internal control over financial reporting. Management reviewed the results of the assessment with the audit committee of the board of directors. Based on its assessment, management determined that, as of December 31, 2023, it maintained effective internal control over financial reporting.
 Grant Thornton LLP, the independent registered public accounting firm that audited the consolidated financial statements of the Partnership included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of the Partnership's internal control over financial reporting as of December 31, 2023. The report, which expresses an unqualified opinion on the effectiveness of the Partnership's internal control over financial reporting as of December 31, 2023, is included in this Item under the heading "Report of Independent Registered Public Accounting Firm".
 Changes in Internal Control over Financial Reporting
 There have been no changes in our internal control over financial reporting during the three months ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
 From time to time, we make changes to our internal control over financial reporting that are intended to enhance its effectiveness and which do not have a material effect on our overall internal control over financial reporting. We will continue to evaluate the effectiveness of our disclosure controls and procedures and internal control over financial reporting on an ongoing basis and will take action as appropriate.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 Board of Directors of Sunoco GP LLC and
 Unitholders of Sunoco LP
 Opinion on internal control over financial reporting
 We have audited the internal control over financial reporting of Sunoco LP (a Delaware limited partnership) and subsidiaries (the "Partnership") as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.
 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated financial statements of the Partnership as of and for the year ended December 31, 2023, and our report dated February 16, 2024 expressed an unqualified opinion on those financial statements.
 Basis for opinion
 The Partnership's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Partnership's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 Definition and limitations of internal control over financial reporting
 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 Item 10. Directors, Executive Officers and Corporate Governance
 Board of Directors
 Our general partner, Sunoco GP LLC (our "General Partner"), manages and directs our operations and activities. The membership interest in our General Partner is solely owned by Energy Transfer LP ("Energy Transfer"). As the sole member of our General Partner, Energy Transfer is entitled under the limited liability company agreement of our General Partner to appoint all directors of our General Partner. Our General Partner's limited liability company agreement provides that our General Partner's Board of Directors (the "Board") shall consist of between three and twelve persons, at least three of whom are required to qualify as independent directors. As of December 31, 2023, the Board consisted of six persons, four of whom qualify as "independent" under the listing standards of the NYSE and our governance guidelines. Our Board has affirmatively determined that the directors who qualify as "independent" under the NYSE's listing standards, SEC rules and our governance guidelines are Oscar A. Alvarez, Imad K. Anbouba, Ray W. Washburne and David K. Skidmore.
 As a limited partnership, we are not required by the rules of the NYSE to seek unitholder approval for the election of any of our directors. We do not have a formal process for identifying director nominees, nor do we have a formal policy regarding consideration of diversity in identifying director nominees. We believe, however, that the individuals appointed as directors have experience, skills and qualifications relevant to our business and have a history of service in senior leadership positions with the qualities and attributes required to provide effective oversight of the Partnership.
 The Board's Role in Risk Oversight
 Our Board generally administers its risk oversight function as a whole. It does so in part through discussion and review of our business, financial and corporate governance practices and procedures, with opportunity for specific inquires of management. In addition, at each regular meeting of the Board, management provides a report of the Partnership's operational and financial performance, which often prompts questions and feedback from the Board. The audit committee provides additional risk oversight through its quarterly meetings, where it discusses policies with respect to risk assessment and risk management, reviews contingent liabilities and risks that may be material to the Partnership and assesses major legislative and regulatory developments that could materially impact the Partnership's contingent liabilities and risks. The audit committee is required to discuss any material violations of our policies brought to its attention on an ad hoc basis. Additionally, the compensation committee reviews our overall compensation program and its effectiveness at both linking executive pay to performance and aligning the interests of our executives and our unitholders.
 Committees of the Board of Directors
 The Board has established standing committees to consider designated matters. The standing committees of the Board are: the audit committee and the compensation committee. The listing standards of the NYSE do not require boards of directors of publicly traded limited partnerships to be composed of a majority of independent directors, nor are they required to have a standing nominating or compensation committee. Notwithstanding, the Board has elected to have a standing compensation committee. We do not have a nominating committee in view of the fact that Energy Transfer, which owns our General Partner, appoints the directors to our Board. The Board has adopted governance guidelines for the Board and charters for each of the audit and compensation committees.
 Audit Committee
 We are required to have an audit committee of at least three members, and all of its members are required to meet the independence and experience standards established by the NYSE and the Exchange Act. The current members of the audit committee are Oscar A. Alvarez, Imad K. Anbouba and David K. Skidmore, each of whom are independent under the NYSE's standards and SEC's rules for audit committee members. In addition, the Board has determined that Mr. Skidmore, who serves as chairman of the audit committee, has "accounting or related financial management expertise" and constitutes an "audit committee financial expert," in accordance with SEC and NYSE rules and regulations.
 The audit committee assists the Board in its oversight of the integrity of our consolidated financial statements and our compliance with legal and regulatory requirements and partnership policies and controls. The audit committee meets on a regularly-scheduled basis with our independent accountants at least four times each year and is available to meet at their request. Our

 independent registered public accounting firm has been given unrestricted access to the audit committee and our management, as necessary. The audit committee has the authority and responsibility to review our external financial reporting, to review our procedures for internal auditing and the adequacy of our internal accounting controls, to consider the qualifications and independence of our independent accountants, to engage and resolve disputes with our independent accountants, including the letter of engagement and statement of fees relating to the scope of the annual audit work and special audit work that may be recommended or required by the independent accountants, and to engage the services of any other advisors and accountants as the audit committee deems advisable. The committee reviews and discusses the audited consolidated financial statements with management, discusses with our independent auditors matters and makes recommendations to the Board relating to our audited consolidated financial statements. In addition, the audit committee is authorized to recommend to the Board any changes or modifications to its charter that the committee believes may be required. The charter of the audit committee is publicly available on our website at  The audit committee held four meetings during 2023.
 Compensation Committee
 Although we are not required under NYSE rules to appoint a compensation committee because we are a limited partnership, the Board established a compensation committee to establish standards and make recommendations concerning the compensation of our officers and directors. The compensation committee is currently chaired by Mr. Alvarez and includes Mr. Anbouba. In addition, the compensation committee determines and establishes the standards for any awards to employees and officers providing services to us under the equity compensation plans adopted by our unitholders, including the performance standards or other restrictions pertaining to the vesting of any such awards. Pursuant to the charter of the compensation committee, a director serving as a member of the compensation committee may not be an officer of or employed by our General Partner, us or our subsidiaries. During 2023, neither Mr. Alvarez nor Mr. Anbouba was an officer or employee of affiliates of Energy Transfer, or served as an officer of any company with respect to which any of our executive officers served on such company's board of directors. In addition, neither Mr. Alvarez nor Mr. Anbouba is a former employee of affiliates of Energy Transfer. The charter of the compensation committee is publicly available on our website at  The compensation committee held four meetings during 2023.
 Code of Ethics
 The Board has approved a Code of Business Conduct and Ethics which is applicable to all directors, officers and employees of our General Partner and its affiliates, including the principal executive officer, the principal financial officer and the principal accounting officer. The Code of Business Conduct and Ethics is available on our website at  (under the 'Investor Relations/Corporate Governance' tab) and in print without charge to any unitholder who sends a written request to our secretary at our principal executive offices at 8111 Westchester Drive, Suite 400, Dallas, Texas 75225. We intend to post any amendments of this code, or waivers of its provisions applicable to directors or executive officers of our General Partner, including its principal executive officer, principal financial officer and principal accounting officer, at this location on our website.
 Corporate Governance Guidelines
 The Board has adopted a set of Corporate Governance Guidelines to promote a common set of expectations as to how the Board and its committees should perform their functions. These principles are published on our website at  and reviewed by the Board annually or more often as the Board deems appropriate.
 Meetings of Non-Management Directors and Communications with Directors
 In accordance with our Corporate Governance Guidelines, the Board holds executive sessions of non-management directors not less than twice annually. These meetings are presided over, on a rotating basis, by the chairman of the audit and compensation committees of the Board. Interested parties may contact the chairman of our audit or compensation committee, or our independent or non-management directors individually or as a group, utilizing the contact information set forth on our website at

 Section 16(a) Beneficial Ownership Reporting Compliance
 Each director and executive officer (and, for a specified period, certain former directors and executive officers) of our General Partner and each holder of more than 10% of a class of our equity securities is required to report to the SEC his or her pertinent position or relationship, as well as transactions in those securities, by specified dates.
 Delinquent Section 16(a) Reports
 Based solely upon a review of reports on Forms 3 and 4 (including any amendments) furnished to us during our most recent fiscal year and written representations from officers and directors of our General Partner that no Form 5 was required, we believe that all filings applicable to our General Partner's officers and directors, and our beneficial owners, required by Section 16(a) of the Exchange Act were filed on a timely basis during 2023, except for one late Form 4 filing by Mr. Curia.
 Reimbursement of Expenses of our General Partner
 Our General Partner does not receive any management fee or other compensation for its management of us. Our General Partner is reimbursed for all expenses incurred on our behalf. These expenses include all expenses necessary or appropriate to the conduct of our business and are allocable to us, as provided for in our partnership agreement. There is no cap on the amount that may be paid or reimbursed to our General Partner.

 Item 11. Executive Compensation
 As is commonly the case for many publicly traded limited partnerships, we do not have officers or directors. Instead, we are managed by the board of directors of our General Partner, and the executive officers of our General Partner perform all of our management functions. As a result, the executive officers of our General Partner are essentially our executive officers. Because Energy Transfer controls our General Partner and owns a significant limited partner interest in us, Energy Transfer will be referenced throughout this Item 11. References to "our officers" and "our directors" refer to the officers and directors of our General Partner.
 Compensation Discussion and Analysis
 Named Executive Officers
 This Compensation Discussion and Analysis is focused on the total compensation of the executive officers of our General Partner as set forth below. The executive officers we refer to in this discussion as our "named executive officers," or "NEOs," for the 2023 fiscal year are the following officers of our General Partner:

 Name
 Principal Position

 President and Chief Executive Officer

 Dylan A. Bramhall
 Chief Financial Officer

 Executive Vice President, Chief Operations Officer

 Senior Vice President, Chief Sales Officer

 Senior Vice President, Chief Commercial Officer

 Our board of directors has established a compensation committee to review and make decisions with respect to the compensation determinations of our officers and directors. In this discussion, we refer to our compensation committee as the "Compensation Committee." However, our Compensation Committee consults with and receives guidance and input, as appropriate, from Energy Transfer's Compensation Committee, Energy Transfer's Executive Chairman of the board of directors, and Energy Transfer's Executive Vice President and Chief Human Resources Officer to ensure compensation decisions are undertaken consistent with the compensation philosophy and objectives set by Energy Transfer.
 In addition to his role as the Chief Financial Officer of our General Partner, Mr. Bramhall also serves as Executive Vice President and Group Chief Financial Officer of Energy Transfer's general partner. Prior to 2023, Mr. Bramhall's compensation was handled on a dual basis with the management of Energy Transfer, setting Mr. Bramhall's salary, long-term incentive pool targets and annual bonus targets and awards of long-term incentives and annual bonus amounts attributable to his services to Energy Transfer and the Compensation Committee directly approved the portions of Mr. Bramhall's long-term incentives and annual bonus attributable to his services to SUN. Beginning with 2023, 100% of Mr. Bramhall's compensation became attributable to Energy Transfer.
 Compensation Philosophy and Objectives
 Generally, our compensation philosophy and objectives are substantially the same as those set by Energy Transfer and are based on the premise that a significant portion of each executive's total compensation should be incentive-based or "at-risk" compensation. We also share Energy Transfer's philosophy that executives' total compensation levels should be competitive in the marketplace for executive talent and abilities. Our General Partner seeks a total compensation program for our NEOs that provides for an annual base compensation rate slightly below the median market (i.e., approximately the 30th to 40th percentile of market) but incentive-based compensation composed of a combination of compensation vehicles designed to reward both short- and long-term performance that are both targeted to pay out at approximately the top-quartile of market for similarly situated businesses. Our General Partner believes the incentive-based balance is achieved by (i) the payment of annual discretionary cash bonuses that consider the achievement of the financial performance objectives for a fiscal year set at the beginning of such fiscal year and the individual contributions of our NEOs to the success of the achievement of the annual financial performance objectives, and (ii) the annual grant of time-based restricted unit and/or restricted phantom unit awards under the long-term incentive plan ("RSUs"), which awards are intended to provide a long-term incentive and retentive value to our key employees to focus their efforts on increasing the market price of our publicly traded units and to increase the cash distribution we pay to our unitholders. While the Partnership utilizes time-based forms of equity awards, the grant date valuation utilizes a modified total unitholder return ("TUR") performance as measured against the average return of Alerian MLP index (AMZ) over defined periods of time. The modified TUR is designed to create a recognition of a performance adjustment to the equity awards based on the prior periods measured to add an element of performance impact in setting grant date value even though the RSUs themselves are a time-vested vehicle. As discussed below, our Compensation Committee, in consultation with our General Partner, and, as applicable Energy Transfer or the Energy Transfer Compensation Committee, are responsible for the compensation policies and compensation level of the named executive officers of our General Partner.

 Our compensation program is structured to achieve the following:
 • reward executives with an industry-competitive total compensation package of competitive base salaries and significant incentive opportunities yielding a total compensation package approaching the top-quartile of the market;
 • attract, retain and reward talented executive officers and key management employees by providing total compensation competitive with that of other executive officers and key management employees employed by publicly traded limited partnerships or other peer companies of similar size and in similar lines of business;
 • motivate executive officers and key employees to achieve strong financial and operational performance;
 • emphasize performance-based or "at-risk" compensation; and
 • reward individual performance.
 Components of Executive Compensation
 For the year ended December 31, 2023, the compensation paid to our NEOs consisted of the following components:
 • annual base salary;
 • non-equity incentive plan compensation consisting solely of discretionary cash bonuses;
 • time-vested RSUs under the equity incentive plan;
 • payment of distribution equivalent rights ("DERs") on unvested time-based RSUs under our equity incentive plan;
 • vesting of previously issued time-based RSUs issued pursuant to equity incentive plans of affiliates; and
 •401(k) plan employer contributions.
 Methodology
 The Compensation Committee considers relevant data available to it to assess our competitive position with respect to base salary, annual short-term incentives and long-term incentive compensation for our executives, including our NEOs. The Compensation Committee also considers individual performance, levels of responsibility, skills and experience.
 Periodically, we engage a third-party consultant to provide the Compensation Committee of our General Partner with market information for compensation levels at peer companies in order to assist in the determination of compensation levels for executives, including the named executive officers. During 2023, Meridian Compensation Partners ("Meridian"), the independent compensation advisor to Energy Transfer completed an evaluation of the market competitiveness of total compensation levels of the senior leadership team, including the named executive officers. The Meridian review provided market information with respect to compensation of Partnership executives, including the named executive officers during the year ended December 31, 2021. In particular, the review by Meridian was designed to (i) evaluate the market competitiveness of total compensation levels for certain members of senior management, including our named executive officers; (ii) assist in the determination of appropriate compensation levels for our senior management, including the named executive officers; and (iii) confirm that our compensation programs were yielding compensation packages consistent with our overall compensation philosophy. The Partnership was reviewed by Meridian through various metrics in order to recognize the Partnership's unique structure, including the facts that (i) the Partnership receives certain shared-service support from Energy Transfer; and (ii) in other functions, the Partnership operates in a manner consistent with an independent publicly-traded organization. As such, Meridian reviewed certain of our executive officers, including the named executive officers, in their specific functions to determine the appropriate benchmarking technique. In all circumstances, Meridian considered our annual revenues and market capitalization levels in its benchmarking. The compensation analysis provided by Meridian covered all major components of total compensation, including annual base salary, annual short-term cash bonus and long-term incentive awards for our named executive officers as compared to officers of companies similarly situated in terms of structure, annual revenues and market capitalization and made determinations with respect to such officers' level (i.e. as a corporate officer, subsidiary officer or shared service function) given the unique characteristics of our structure. In addition to the companies reviewed as part of Meridian's review for benchmarking, SUN will continue to work to refine a "core peer" group that is more identifiable in similar business lines and types as SUN.
 Following Meridian's 2023 review, the Compensation Committee reviewed the information provided, including Meridian's specific summary observations and recommended considerations for all compensation going forward. The observations addressed overall competitive benchmarking, peer company approaches to compensation and short and long-term incentive plan design, the Compensation Committee considered and reviewed the results of the study performed by Meridian to determine if the results indicated that the compensation programs were yielding a competitive total compensation model prioritizing incentive-based compensation and rewarding achievement of short and long-term performance objectives and considered Meridian's conclusions and recommendations. While Meridian found that SUN is continuing to achieve its stated objectives with respect to the "at-risk" approach, Meridian also

 recommended certain adjustments for consideration, which considerations were designed to allow SUN to continue to achieve its targeted percentiles on base compensation and incentive compensation (short and long-term). In respect of the 2023 Meridian review, the Compensation Committee in consultation with Meridian and executive management approved the adoption of the Amended and Restated Sunoco GP LLC Annual Bonus Plan (the "Amended Bonus Plan") effective as January 1, 2023. The Amended Bonus enhanced potential pay-out for achievement of specific performance goals allowing for a maximum Amended Bonus Plan payout of 130% of target as opposed to the prior Bonus Plan maximum payout of 116%. Specific changes are discussed below under the title of Annual Bonus. Certain of Meridian's other suggested considerations as part of the review were implemented and others were determined to require additional review and consideration.
 Following Meridian's review, the Compensation Committee reviewed the information provided, including Meridian's specific conclusions and recommended considerations for all compensation going forward. The Compensation Committee considered and reviewed the results of the study performed by Meridian to determine if the results indicated that the compensation programs were yielding a competitive total compensation model prioritizing incentive-based compensation and rewarding achievement of short and long-term performance objectives and considered Meridian's conclusions and recommendations. In general, Meridian found that the Partnership is largely achieving its stated objectives with respect to the "at-risk" approach and targeted level of compensation for our named executive officers.
 In addition to the information received as part of Meridian's review, the Compensation Committee also has access to information obtained from other sources in its determination of compensation levels for our named executive officers, such as annual third party surveys.
 Base salary. Base salary is designed to provide for a competitive fixed level of pay that attracts and retains executive officers and compensates them for their level of responsibility and sustained individual performance (including experience, scope of responsibility and results achieved). The salaries of our named executive officers are targeted as an annual base salary slightly below median level of market and are determined by the Compensation Committee. Base salaries also are influenced by internal pay equity (fair and consistent application of compensation practices). At the NEO level, the balance of compensation is weighted toward pay-at-risk compensation (annual bonuses and long-term incentives).
 During the 2023 merit review process in July, the Compensation Committee approved base salary increase to each of the named executive officers. Mr. Kim's salary increased to $675,000 from his previous level of $624,000, Mr. Fails' salary increased to $410,494 from his previous level of $391,880, Mr. Hand's salary increased to $375,000 from his previous level of $344,259 and Mr. Harkness' salary increased to $350,000 from his previous level of $305,000. As noted above, Mr. Bramhall no longer receives a salary allocation from SUN effective November 11, 2022. In general, SUN approved a merit pool increase of 4.75 for all of its employees, including the named executive officers. However, in the case of Messrs. Kim (8.17%), Hand (8.93%) and Harkness (14.75%) larger base salary adjustments were approved consistent with the results of the 2023 Meridian review in recognition of their overall benchmarking.
 Executive Compensation Clawback Policy. In November 2023, the Compensation Committee adopted the Sunoco LP Executive Officer Incentive Compensation Clawback Policy (the "Clawback Policy"), which requires the Partnership to recover erroneously awarded incentive-based compensation from executive officers in the event the Partnership is required to prepare an accounting restatement. The Clawback Policy applies to any individual who is currently or was previously designated as an "officer" of the Partnership as defined in Rule 16a-1(f) under the Securities Exchange Act of 1934, including all of our current NEOs. The Clawback Policy is designed to comply with the requirements of the SEC and the NYSE Listed Company Manual, including (i) the definition of an accounting restatement, (ii) the applicable types of incentive-based compensation, (iii) the relevant recovery period, and (iv) the approach for calculating the recovery amount.
 Annual Bonus. In addition to base salary, the Compensation Committee makes a determination whether to award discretionary annual cash bonuses to employees, including our named executive officers, following the end of the year. These discretionary bonuses, if awarded, are intended to reward our named executive officers for the achievement of financial performance objectives during the year for which the bonuses are awarded in light of the contribution of each individual to our profitability and success during such year. As noted the Amended Bonus Plan replaced the Bonus Plan in connection with certain recommendations contained in Merdian's 2023 review.
 The Amended Bonus Plan is a discretionary annual cash bonus plan available to all employees, including the named executive officers. The purpose of the Amended Bonus Plan is to reward employees for contributions towards the Partnership's business goals and to aid in motivating employees. The Amended Bonus Plan is administered by the Compensation Committee and the Compensation Committee has the authority to establish and interpret the rules and regulations relating to the Amended Bonus Plan, to select participants, to determine and approve the size of any actual award amount, to make all determinations, including factual determinations, under the Amended Bonus Plan, and to take all other actions necessary or appropriate for the proper administration of the Bonus Plan.

 Prior to January 1, 2023, the Bonus Plan provided during each calendar year, or any other period designated by the Compensation Committee (the "Performance Period"), for the Compensation Committee to evaluate and determine an overall funded cash bonus pool based on achievement of (i) an internal Adjusted EBITDA target ("Adjusted EBITDA Target"), (ii) an internal distributable cash flow target ("DCF Target") and (iii) performance of each department compared to the applicable departmental budget ("Departmental Budget Target"). For purposes of the Adjusted EBITDA Target and DCF Target established in the Bonus Plan, the measures of Adjusted EBITDA and Distributable Cash Flow are calculated using the same definitions as used in the Partnership's publicly reported financial information, including the Partnership's earnings press releases, investor presentations, and annual and quarterly filings on Forms 10-K and 10-Q. The performance criteria were weighted 60% on the achievement of the Adjusted EBITDA Target, 20% on the achievement of the DCF Target and 20% on the achievement of the Departmental Budget Target (collectively "Budget Targets"). The total amount of cash to be allocated to the funded bonus pool will range from 0% to 120% for each of the budgeted DCF Target and Adjusted EBITDA Target and will range from 0% to 100% of the Departmental Budget Target. The maximum funding of the bonus pool is 116% of the total pool target, and to achieve such funding each of the Adjusted EBITDA and the DCF Target must achieve 120% funding and the Department Budget target must achieve its 100% target. While the funded bonus pool will reflect an aggregation of performance under each target, in the event performance under the Adjusted EBITDA Target is below 80% of its target, no bonus pool will be funded. If the bonus pool is funded, a participant may earn a cash award for the Performance Period based upon the level of attainment of the Budget Targets and his or her individual performance. Awards are paid in cash as soon as practicable after the end of the Performance Period but in no event later than two and one-half months after the end of the Performance Period.
 Under the Amended Bonus Plan, for each Performance Period after January 1, 2023, the Compensation Committee will evaluate and determine an overall funded cash bonus pool based on achievement of (i) an Adjusted EBITDA Target, (ii) a DCF Target and (iii) a Departmental Budget Target. Under the Amended Bonus Plan, the Budget Targets were weighted 60% on the achievement of the Adjusted EBITDA Target, 25% on the achievement of the DCF Target and 15% on the achievement of the Departmental Budget Target. Under the Amended Bonus Plan, the DCF Target weighting increased to 25% from 20% under the Bonus and the Budget Target weighting was reduced from 20% to 15%. The total amount of cash to be allocated to the funded bonus pool will range from 0% to 135% for each of the budgeted DCF Target and Adjusted EBITDA Target and will range from 0% to 100% of the Departmental Budget Target. The increased range on the funded bonus pool to 135% of the budgeted DCF Target and Adjusted EBITDA Target under the Amended Bonus Plan represented an increase from 120% each under the Bonus Plan.
 The maximum funding of the bonus pool of 130% of the total pool target under the Amended Bonus Plan is an increase from 116% under the Bonus Plan. Maximum funding of the Adjusted EBITDA and the DCF Target under the Amended Bonus Plan requires achievement of 110% of the target as opposed to 120% under the Bonus Plan. The maximum funding of the Amended Bonus Plan at 130% is an increase from the 116% maximum under the Bonus Plan.
 While the funded bonus pool will reflect an aggregation of performance under each target, in the event performance under the Adjusted EBITDA Target is below 80% of its target, no bonus pool will be funded. If the bonus pool is funded, a participant may earn a cash award for the Performance Period based upon the level of attainment of the Budget Targets and his or her individual performance. Awards under both the Bonus Plan and the Amended Bonus Plan are paid in cash as soon as practicable after the end of the Performance Period but in no event later than two and one-half months after the end of the Performance Period.
 For 2023, the short-term annual cash bonus pool targets for Messrs. Kim, Fails, Hand and Harkness were as follows: 130% for Mr. Kim, 110% for Mr. Fails, and 105% for Messrs. Hand and Harkness. As noted above, Mr. Bramhall no longer receives a bonus allocation from SUN effective November 11, 2022.
 While the achievement of the various budget targets sets a bonus pool under the Bonus Plan and the Amended Bonus Plan, actual bonus awards are discretionary. These discretionary bonuses, if awarded, are intended to reward our named executive officers for the achievement of the budget targets during the performance period in light of the contribution of each individual to our profitability and success during such year. The Compensation Committee does not establish its own financial performance objectives in advance for purposes of determining whether to approve any annual bonuses, and it does not utilize any formulaic approach to determine annual bonuses.
 In February 2024, the Compensation Committee certified Partnership results to achieve a bonus payout of the bonus pool. The actual results reflected the achievement of approximately 107% of the Adjusted EBITDA Target, 104% of the DCF Target and 100% of the Departmental Budget Target. The Compensation Committee based on achieved results approved a 120% of the achieved pool target. The cash bonuses approved for Messrs. Kim, Fails, Hand and Harkness were $1,015,000, $530,000, $454,000 and $413,000, respectively.
 In approving the 2023 bonuses of the named executive officers, the Compensation Committee took into account the achievement by the Partnership of all of the targeted performance objectives for 2023 and the individual performances of each of the named executive officers. The cash bonuses awarded to each of the named executive officers for 2023 performance were materially consistent with their applicable bonus pool targets.

 Equity Awards. Each of the Sunoco LP 2012 Long-Term Incentive Plan (the "2012 LTIP") and the Sunoco LP 2018 Long-Term Incentive Plan (the "2018 LTIP," and together with the 2012 LTIP, the "LTIPs") is designed to provide long-term incentive awards in order to promote achievement of our long-term strategic business objectives. The LTIPs are designed to align the economic interests of the named executive officers, key employees and directors with those of our unitholders and to provide an incentive to management for continuous employment with the General Partner and its affiliates. Each of our named executive officers is eligible to participate in the LTIPs. These awards are intended to align the interests of plan participants (including our NEOs) with those of our unitholders and to give plan participants the opportunity to share in our long-term performance.
 From time to time, the Compensation Committee may make grants under the plan to employees and/or directors containing such terms as the Compensation Committee shall determine under the LTIPs. The Compensation Committee determines the conditions upon which the restricted units granted may become vested or forfeited, and whether or not any such restricted units will have DERs entitling the grantee to receive an amount in cash equal to cash distributions made by us with respect to a like number of our common units during the restricted period.
 For 2023, the annual long-term incentive targets set by the Compensation Committee for the named executive officers were 500% of annual base salary for Mr. Kim, 300% for Mr. Fails, and 200% for Messrs. Hand and Harkness. Mr. Bramhall's 2023 Energy Transfer equity award was at a target of 500%.
 The annual long-term incentive targets are used as the basis to determine the target number of units to be awarded to the eligible participant, including the named executive officers. A multiple of base salary is used to set the pool target, that number is then divided by a weighted average price determined by considering SUN's modified TUR performance as measured against the average return of Alerian MLP index (AMZ) over defined time periods. In previous years, the comparison was conducted against an independently identified peer group. The change to using the AMZ for the TUR analysis beginning for 2022 awards was a recognition of the challenge of matching SUN's business with an adequate set of peer companies for performance evaluation. It was determined that the AMZ would provide the most adequate basis for analysis. SUN will continue to evaluate the best and most adequate tool to appropriately measure an appropriate modified TUR analysis and will make changes as appropriate in future years. The modified TUR is designed to create a recognition of performance adjustment based on the prior periods measured to an element of performance impact in setting grant date value even though the RSUs themselves are a time-vested vehicle. For purposes of establishing an initial price, we utilize a 60 trading-day trailing weighted average price of SUN common units prior to November 1 of the respective year. This average trading price is then subject to adjustment when our TUR is more than 10% greater or less than that of companies within the AMZ. If the TUR analysis yields a result that is within 10% of the AMZ, the Compensation Committee will simply use the 60 trading day trailing weighted average price divided by the applicable salary multiple to establish a target pool for each eligible participant, including the named executive officers. If our TUR is outside of the 10% deviation, the 60 trading day trailing weighted average will be adjusted. For purposes of the adjustment to the trailing average we will consider deviations from 10% to 30% up or down, which number will then be divided by two to establish a maximum of 15% either way from the trailing weighted average price based on SUN's performance as compared to the AMZ.
 For 2023, the Partnership's TUR was within 10% of the AMZ the applicable measurement period, as such the Compensation Committee used the 60 day trailing weighted average price to establish the total available pool.
 In December 2023, the Compensation Committee granted RSU awards to Messrs. Kim, Fails, Hand, and Harkness 70,000 units, 30,000 units, 20,500 units and 20,500 units, respectively, under the 2018 LTIP. In approving the grant of such RSUs, the Compensation Committee considered several factors, including the long-term objective of retaining such individuals as key drivers of the Partnership's future success, the existing level of equity ownership of such individuals and the previous awards to such individuals of equity awards subject to vesting.
 In December 2023, Mr. Bramhall received a grant of equity awards by the Energy Transfer Compensation Committee in connection with his service to Energy Transfer's general partner, with such awards including 189,750 Energy Transfer restricted units and 63,250 Energy Transfer cash restricted units.
 Vesting of the 2023 awards would accelerate in the event of the death or disability of the named executive officer or in the event of a change in control of the partnership as that term is defined under the 2018 LTIP.
 All of the RSUs granted, including to the named executive officers, provided for the vesting of 60% of the units at the end of the third year from the date of the grant and the vesting of the remaining 40% of the units at the end of the fifth year, subject to continued employment of the named executive officers through each specified vesting date. These RSUs entitle the grantee of the unit awards to receive, with respect to each Partnership common unit subject to such RSU that has not either vested or been forfeited, a DER cash payment promptly following each such distribution by us to our unitholders. In approving the grant of such unit awards, the Compensation Committee took into account a number of performance factors as well as the long-term objective of retaining such individuals as key drivers of the Partnership's future success, the existing level of equity ownership of such individuals and the previous awards to such individuals of equity awards subject to vesting.

 As discussed below under "Potential Payments Upon a Termination or Change of Control," all outstanding equity awards would automatically accelerate upon a change in control event, which means vesting automatically accelerates upon a change of control irrespective of whether the officer is terminated. In addition, the award agreements also include certain acceleration provisions upon retirement with the ability to accelerate 40% of outstanding unvested awards under the Energy Transfer Incentive Plans at age 65 and 50% at age 68. These acceleration provisions require that the participant have not less than five (5) years of employment service to the Partnership or an affiliate and are subject to the applicable provisions of IRC Section 409(A), which may include a six (6) month delay in the vesting after retirement. Beginning in 2022, the retirement provision also requires that the award be held for at least one year after the grant date in order to be eligible for acceleration.
 The issuance of common units pursuant to our equity incentive plans is intended to serve as a means of incentive compensation; therefore, no consideration will be payable by the plan participants upon vesting and issuance of the common units.
 We believe that permitting the accelerated vesting of equity awards upon a change in control creates an important retention tool for us by enabling employees to realize value from these awards in the event that we undergo a change in control transaction. The actual value to be realized upon any acceleration is discussed below under "Potential Payments Upon a Termination or Change of Control."
 Benefit Plans. Our NEOs are provided compensation in the form of other benefits, including medical, life, dental, and disability insurance in line with competitive market conditions in retail non-store plans sponsored by Sunoco GP LLC. Our NEOs receive the same benefits and are responsible to pay the same premiums, deductibles and out of pocket maximums as other employees participating in these plans.
 Sunoco GP LLC 401(k) Plan. Effective December 31, 2018, our previous 401(k) benefit plan, the Sunoco GP LLC 401(k), was merged into the Energy Transfer LP 401(k) Plan (the "ET 401(k) Plan"). The ET 401(k) Plan is a defined contribution 401(k) plan, which covers substantially all of our employees, including the named executive officers. Employees may elect to defer up to 100% of their eligible compensation after applicable taxes, as limited under the Internal Revenue Code. We make a matching contribution that is not less than the aggregate amount of matching contributions that would be credited to a participant's account based on a rate of match equal to 100% of each participant's elective deferrals up to 5% of covered compensation. The amounts deferred by the participant are fully vested at all times, and the amounts contributed by the Partnership become vested based on years of service. We provide this benefit as a means to incentivize employees and provide them with an opportunity to save for their retirement.
 The Partnership provides a 3% profit sharing contribution to employee 401(k) accounts for all employees with a base compensation below a specified threshold. The contribution is in addition to the 401(k) matching contribution and employees become vested based on years of service.
 Sunoco GP LLC Severance Plan. In addition, Sunoco GP LLC has also adopted the SUN Severance Plan, which provides for payment of certain severance benefits in the event of Qualifying Termination (as that term is defined in the SUN Severance Plan). In general, the Severance Plan provides payment of one (1) week of annual base salary for each year or partial year of employment service, up to a maximum of fifty-two weeks or one year of annual base salary (with a minimum of eight weeks of annual base salary) and up to three months of continued group health insurance coverage. The SUN Severance Plan also provides that additional benefits in addition to those provided under the Severance Plan may be paid based on special circumstances, which additional benefits shall be unique and non-precedent setting. The Severance Plan is available to all salaried employees on a nondiscriminatory basis; therefore, amounts that would be payable to the named executive officers upon a Qualified Termination have been excluded from "Compensation Tables - Potential Payments Upon a Termination or Change of Control" below.
 The benefit levels are summarized below:

 Other Energy Transfer Sponsored Benefit Plans. Our NEOs participate in certain retirement and deferred compensation plans sponsored by Energy Transfer or its affiliates as described below. The Partnership is not allocated any compensation expense nor does it make any contributions to the plans sponsored by Energy Transfer or its affiliates.
 Energy Transfer Non-Qualified Deferred Compensation Plan (the "ET NQDC Plan") is a deferred compensation plan, which permits eligible highly compensated employees to defer a portion of their salary, bonus and/or quarterly non-vested restricted unit and/or restricted phantom unit distribution equivalent income until retirement, termination of employment or other designated distribution event. Each year under the ET NQDC Plan, eligible employees are permitted to make an irrevocable election to defer up to 50% of their annual base salary, 50% of their quarterly non-vested restricted unit and/or restricted phantom unit distribution equivalent

 income, and/or 50% of their discretionary performance bonus compensation during the following year. Pursuant to the ET NQDC Plan, Energy Transfer may make annual discretionary matching contributions to participants' accounts; however, Energy Transfer has not made any discretionary contributions to participants' accounts and currently has no plans to make any discretionary contributions to participants' accounts. All amounts credited under the ET NQDC Plan (other than discretionary credits) are immediately 100% vested. Participant accounts are credited with deemed earnings or losses based on hypothetical investment fund choices made by the participants among available funds.
 Participants may elect to have their account balances distributed in one lump sum payment or in annual installments over a period of three or five years upon retirement, and in a lump sum upon other termination events. Participants may also elect to take lump-sum in-service withdrawals five years or longer in the future, and such scheduled in-service withdrawals may be further deferred prior to the withdrawal date. Upon a change in control (as defined in the ET NQDC Plan) of Energy Transfer, all ET NQDC Plan accounts are immediately vested in full. However, distributions are not accelerated and, instead, are made in accordance with the ET NQDC Plan's normal distribution provisions unless a participant has elected to receive a change of control distribution pursuant to his deferral agreement.
 Risk Assessment Related to Our Compensation Structure
 We believe our compensation plans and programs for our named executive officers, as well as the other employees who provide services to us, are appropriately structured and are not reasonably likely to result in material risk to us. We believe our compensation plans and programs are structured in a manner that does not promote excessive risk-taking that could harm our value or reward poor judgment. We also believe we have allocated our compensation among base salary and short and long-term compensation in such a way as to not encourage excessive risk-taking. We use restricted units and/or restricted phantom units rather than unit options for equity awards because restricted units and/or restricted phantom units retain value even in a depressed market so that employees are less likely to take unreasonable risks to get, or keep, options "in-the-money." Finally, the time-based vesting over five years for our long-term incentive awards ensures that our employees' interests align with those of our unitholders for our long-term performance.
 Accounting and Tax Considerations
 We account for the equity compensation expense for equity awards granted under our LTIP in accordance with U.S. generally accepted accounting principles ("GAAP"), which requires us to estimate and record an expense for each equity award over the vesting period of the award. For restricted units and/or restricted phantom units that are paid out in the form of common units, the value of our common units on the date of grant is used for determining the expense. The expense for restricted units and/or restricted phantom units settled in common units is recognized ratably over the vesting period. For cash compensation, the accounting rules require us to record it as an expense at the time the obligation is accrued. Because we are a partnership, and our General Partner is a limited liability company, Internal Revenue Code ("Code") Section 162(m) does not apply to the compensation paid to our NEOs and, accordingly, our Compensation Committee did not consider its impact in making the compensation recommendations discussed above.
 Compensation Committee Interlocks and Insider Participation
 Messrs. Alvarez and Anbouba were the only members of the Compensation Committee during 2023. During 2023, neither Mr. Alvarez nor Mr. Anbouba was an officer or employee of affiliates of Energy Transfer, or served as an officer of any company with respect to which any of our executive officers served on such company's board of directors. In addition, neither of the current Compensation Committee members is a former employee of affiliates of Energy Transfer.
 Compensation Committee Report
 The Compensation Committee of the board of directors of our General Partner has reviewed and discussed the section of this report entitled "Compensation Discussion and Analysis" with the management of the Partnership and approved its inclusion on this annual report on Form 10-K.
 Compensation Committee
 Oscar A. Alvarez (Chairman)
 The foregoing report shall not be deemed to be incorporated by reference by any general statement or reference to this Annual Report on Form 10-K into any filing under the Securities Act, as amended, or the Exchange Act, as amended, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under those Acts.

 (1)In accordance with the terms of our partnership agreement, we reimburse our General Partner and its affiliates for compensation related expenses attributable to the portion of the named executive officer's time dedicated to providing services to us. For the periods presented, amounts reported herein reflect 100% of the base salary associated with the NEO's services, except for Mr. Bramhall's base salary which is allocated at 40% based on the portion of his compensation attributable to SUN prior to his promotion on November 11, 2022. Cash compensation expenses for each NEO were allocated on the basis of total cash compensation earned by the NEO during the period.
 (2)The amounts reported for unit awards represent the full grant date fair value of RSUs granted to each of our NEOs, computed in accordance with FASB ASC Topic 718, disregarding any estimates for forfeitures. For Mr. Bramhall, the amounts reported above include only his grants of Sunoco LP restricted units and exclude grants of Energy Transfer plan-based awards. For Mr. Bramhall, the amount attributable to SUN represents 20% of his total award.
 (3)Sunoco LP maintains the Bonus Plan which provides for annual bonuses. Awards of bonuses are tied to achievement of targeted performance objectives and described in the Compensation Discussion and Analysis. In respect of Mr. Bramhall's 2023 bonus award, 100% of his bonus will be awarded under the Energy Transfer bonus plan and is 100% attributable to Energy Transfer.
 (4)The amounts reflected for 2023 in this column include (i) 401(k) Plan matching contributions made on behalf of the named executive officers of $12,900 for Mr. Kim, $16,500 for Mr. Fails, $14,307 for Mr. Hand, and $16,375 for Mr. Harkness, (ii) health savings account contributions made on behalf of the named executive officers of $2,000 each for Messrs. Kim, Fails and Hand, and (iii) the dollar value of life insurance premiums paid for the benefit of the named executive officers of $1,932 for Mr. Kim, $994 for Mr. Fails, $2,528 for Mr. Hand and $530 for Mr. Harkness.
 (5)Mr. Bramhall's compensation is reported in detail in Item 11 of the Energy Transfer LP Annual Report on Form 10-K. All compensation decisions impacting Mr. Bramhall are made by the Compensation Committee of LE GP LLC, the general partner of Energy Transfer LP. As noted in the compensation discussion and analysis above, 100% of Mr. Bramhall's 2023 compensation, other than the $211,815 in DERs paid on his unvested Sunoco LP restricted units was attributable to Energy Transfer LP. All compensation decisions for 2023, were made by the Compensation Committee of LE GP LLC. Prior to 2023, Mr. Bramhall's compensation was handled on a dual basis with the management of Energy Transfer, setting Mr. Bramhall's salary, long-term incentive pool targets and annual bonus targets and awards of long-term incentives and annual bonus amounts attributable to his services to Energy Transfer and the Compensation Committee directly approving the portions of Mr. Bramhall's long-term incentives and annual bonus attributable to his services to SUN.
 The amounts reflected for all periods exclude distribution payments in connection with DERs on unvested unit awards, because the dollar value of such distributions are factored into the grant date fair value reported in the "Unit Awards" column of the Summary Compensation Table at the time that the unit awards and DERs were originally granted. For 2023, distribution payments in connection with DERs totaled $975,273 for Mr. Kim, $211,815 for Mr. Bramhall (excluding distributions related to Energy Transfer unit awards), $453,793 for Mr. Fails, $288,397 for Mr. Hand, and $214,496 for Mr. Harkness.

 Potential Payments upon Termination or Change of Control
 Pursuant to the terms of the award agreements issued under the LTIP, in the event of a (i) Change of Control (as defined in the LTIPs, summarized below) or (ii) termination of employment due to death or disability, all RSUs shall vest. In the event of a termination of employment for any other reason, all RSUs that are still unvested shall be forfeited. The RSUs that would vest in the event of Change of Control are those RSU's described for each NEO in the table entitled "Outstanding Equity Awards at December 31, 2023".
 In addition, awards under both the 2012 LTIP and the 2018 LTIP contain a partial acceleration of vesting for qualified retirement, whereby a recipient who voluntarily retires after at least five years of service would be eligible for (i) vesting of 40% of the outstanding award, if the recipient retires at age 65 to 68, or (ii) vesting of 50% of the outstanding award, if the recipient is over the age of 68 upon retirement. Currently, none of our NEOs are eligible for partial acceleration upon retirement. The acceleration of these awards at retirement is subject to the provisions of IRC Section 409A and such accelerated units shall not be delivered before the earlier of (i) the day that is six months plus one day after the date of separation from service or (ii) the tenth (10th) day after the date of the recipient's death.
 Under the LTIPs, a "Change of Control" means, and shall be deemed to have occurred upon one or more of the following events: (i) any "person" or "group" within the meaning of those terms as used in Sections 13(d) and 14(d)(2) of the Exchange Act, other than members of the General Partner, the Partnership, or an affiliate of either the General Partner or the Partnership, shall become the beneficial owner, by way of merger, consolidation, recapitalization, reorganization or otherwise, of 50% or more of the voting power of the voting securities of the General Partner or the Partnership; (ii) the limited partners of the General Partner or the Partnership approve, in one transaction or a series of transactions, a plan of complete liquidation of the General Partner or the

 Partnership; (iii) the sale or other disposition by either the General Partner or the Partnership of all or substantially all of its assets in one or more transactions to any Person other than an affiliate; (iv) the General Partner or an affiliate of the General Partner or the Partnership ceases to be the General Partner of the Partnership; (v) any other event specified as a "Change of Control" in the equity incentive plan maintained by the Partnership at the time of such "Change of Control;" or (vi) any other event specified as a "Change of Control" in an applicable award agreement. Notwithstanding the above, with respect to a 409A award, a "Change of Control" shall not occur unless that Change of Control also constitutes a "change in the ownership of a corporation," a "change in the effective control of a corporation," or a "change in the ownership of a substantial portion of a corporation's assets," in each case, within the meaning of 1.409A-3(i)(5) of the 409A regulations, as applied to non-corporate entities.
 The following table shows the amount of incremental value that would have been received by each of the NEOs upon certain events of termination or a change of control resulting in the accelerated vesting of the restricted units and/or restricted phantom units held by our NEOs on December 31, 2023:

 CEO Pay Ratio
 In accordance with Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, set forth below is information about the relationship of the annual total compensation of Mr. Kim, our President and Chief Executive Officer, and the annual total compensation of our employees.
 For the 2023 calendar year:
 • The annual total compensation of Mr. Kim, as reported in the Summary Compensation Tables of this Item 11 was $5,485,307; and
 • The median total compensation of the employees supporting our Partnership (other than Mr. Kim) was $93,303 for 2022, which "median employee" will be used for the 2023 analysis.
 Based on this information, for 2023 the ratio of the annual total compensation of Mr. Kim to the median of the annual total compensation was approximately 59 to 1.
 To identify the median of the annual total compensation of the employees supporting the Partnership, the following steps were taken:
 1.It was determined that, as of December 31, 2023, the applicable employee populations consisted of 2,389 with all of the identified individuals being employed in the United States. This population consisted of all of our full-time and part-time employees. We did not engage any independent contractors in 2023 that are required to be included in our employee population for the CEO pay ratio evaluation.
 2.To identify the "median employee" from our employee population, we compared the total earnings of our employees as reflected in our payroll records as reported on Form W-2 for 2023.
 3.We identified our median employee using W-2 reporting and applied this compensation measure consistently to all of our employees required to be included in the calculation. We did not make any cost of living adjustments in identifying the "median employee".

 4.Once we identified our median employee, we combined all elements of the employee's compensation for 2023 resulting in an annual compensation of $93,303, with cash compensation of $74,046. The difference between such employee's total earnings and the employee's total compensation represents the estimated value of the employee's health care benefits (estimated for the employee and such employee's eligible dependents at $12,935 and the employee's 401(k) matching contribution and profit sharing contribution, as applicable estimated at $6,322 per employee).
 5.With respect to Mr. Kim, we used the amount reported in the "Total" column of our 2023 Summary Compensation Table under this Item 11.
 Compensation of Directors
 Our Board periodically reviews and determines the amounts payable to the members of our Board. For 2023, the directors of the General Partner who were not employees of the General Partner or its affiliates received, as applicable: an annual cash retainer of $100,000; an annual cash retainer of $15,000 ($25,000 for the chair) for serving on our audit committee; an annual cash retainer of $7,500 ($15,000 for the chair) for serving on our Compensation Committee; and a cash fee for the engagement of the special committee of the Board (the "Special Committee"), as determined by the Board at the time of such engagement. Such directors also received an annual grant of RSUs under the LTIP equal to an aggregate of $125,000 based on the same grant date valuation as is used for annual long-term incentive awards made to Partnership officers, including the named executive officers, through the annual modified total unitholder return analysis. Directors appointed during the year, or who cease to be directors during a year, receive a pro-rated portion of any cash retainers. In addition, each non-employee director who is appointed to the Board for the first time is entitled to receive 2,500 unvested SUN common units. Unit awards granted to non-employee directors will vest 60% after the third year and the remaining 40% after the fifth year after the grant date.
 Under the LTIP, the director will forfeit all unvested RSUs upon a termination of his duties as a director for any reason. If the director ceases providing services due to death or disability (as defined by the LTIP) prior to the date all RSUs units have vested, then all restrictions lapse and all RSUs become immediately vested. If a Change of Control (as defined under the LTIP) occurs, then all unvested RSUs become fully vested as of the date of the Change of Control. In addition, our directors will be reimbursed for out-of-pocket expenses incurred in connection with attending meetings of the Board or its committees.
 The following table provides a summary of compensation paid to each of our current and former non-employee directors (and Mr. Curia) with respect to 2023:

 (1)The amounts in this column reflect the aggregate dollar amount of fees earned or paid in cash including the annual retainer fee.
 (2)The amounts reported for unit awards represent the full grant date fair value of the awards granted in 2023, calculated in accordance with FASB ASC Topic 718, disregarding any estimate for forfeiture. These amounts do not correspond to the actual value that may be recognized by the recipient upon any disposition of vested units and do not give effect to any decline or increase in the trading price of our common units since the date of grant. For a discussion of the assumptions and methodologies used in calculating the grant date fair value of the unit awards reported above, see Note 18 in our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data."
 As discussed above, the number of units awarded is based on the annual award amount of $125,000 divided by the same grant-date valuation as is used for annual long-term incentive award to Partnership officers through the modified total unitholders return analysis.
 (3)Mr. Curia (Energy Transfer's EVP and Chief Human Resources Officer) is entitled to receive grants of RSUs pursuant to the LTIP in recognition of his commitment and contribution to us and our unitholders. The restricted units granted in December 2023 will vest 60% in December 2026 and 40% in December 2028, subject to the terms of the award agreement. The awards of RSUs to Mr. Curia in respect of his contribution to us represent a portion of his total awards as an executive officer of Energy Transfer and the allocation of such percentage to us is in recognition of the portion of his total time spent on our business.

 As of December 31, 2023, Mr. Alvarez had 11,800 outstanding RSUs, Mr. Anbouba had 11,800 outstanding RSUs, Mr. Skidmore had 8,031 outstanding RSU's and Mr. Washburne had 5,598 outstanding RSUs. Additionally, Mr. Curia had 53,127 outstanding RSUs.

 Procedures for Review, Approval and Ratification of Transactions with Related Persons
 For a discussion of director independence, see "Item 10. Directors, Executive Officers and Corporate Governance."
 The Audit Committee reviews and considers related party transactions with various subsidiaries or affiliates of Energy Transfer. The Audit Committee has authorized the General Partner's management to enter into transactions with entities affiliated to Energy Transfer on arms-length terms taking into account then-current market conditions applicable to the services to be provided, and any such transaction, within management's delegation of authority levels shall be deemed approved by the Audit Committee, provided it is not a new related party transaction that may be material to the Partnership.
 As a policy matter, our Special Committee, comprised of our independent directors, generally reviews any proposed related-party transaction that may be material to the Partnership to determine whether the transaction is fair and reasonable to the Partnership. In determining materiality, our General Partner evaluates several factors including the terms of the transaction, the capital investment required, and the revenues expected from the transaction. While there are no written policies or procedures for the Board to follow in making these determinations, the Board makes those determinations in light of its contractually-limited duties to the Partnership's unitholders. Our Partnership Agreement provides that if the Board, through the Special Committee or otherwise, approves the resolution or course of action taken with respect to a conflict of interest, then it will be presumed that, in making its decision, the Board acted in good faith, and any proceeding brought by or on behalf of any limited partner or the Partnership, the person bringing or prosecuting such proceedings will have the burden of overcoming such presumption (see "Item 1A. Risk Factors - Risks Related to Our Structure" in this annual report on Form 10-K).
 Additionally, we have in place a Code of Business Conduct and Ethics that is applicable to all directors, officers and employees of the Partnership and its subsidiaries and affiliates, that requires the approval by designated executive officers prior to entering into any related party transaction that could present a potential conflict of interest.

 Policy for Approval of Audit and Non-Audit Services
 Our audit committee charter requires that all services provided by our independent public accountants, both audit and non-audit, must be pre-approved by the audit committee. Pre-approval of audit and non-audit services may be given at any time up to a year before commencement of the specified service.
 In determining whether to approve a particular audit or permitted non-audit service, the audit committee will consider, among other things, whether such service is consistent with maintaining the independence of the independent public accountants. The audit committee will also consider whether the independent public accountants are best positioned to provide the most effective and efficient service to us and whether the service might be expected to enhance our ability to manage or control risk or improve audit quality.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 Board of Directors of Sunoco GP LLC and
 Unitholders of Sunoco LP
 Opinion on the financial statements
 We have audited the accompanying consolidated balance sheets of Sunoco LP (a Delaware limited partnership) and subsidiaries (the "Partnership") as of December 31, 2023 and 2022, the related consolidated statements of operations and comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.
 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Partnership's internal control over financial reporting as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"), and our report dated February 16, 2024 expressed an unqualified opinion.
 Basis for opinion
 These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on the Partnership's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
 Critical audit matter
 The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
 Fair value of property and equipment acquired in the Zenith Energy acquisition
 As described further in Note 3 to the consolidated financial statements, the Partnership acquired 16 refined product terminals on May 1, 2023, from Zenith Energy for approximately $111 million. The Partnership utilized a third-party valuation specialist to estimate the fair value of the acquired property and equipment, which was determined to be $110 million. We identified the estimation of the fair value of the acquired property and equipment as a critical audit matter.
 The principal consideration for our determination that the estimation of the fair value of the acquired property and equipment is a critical audit matter is that there was estimation uncertainty due to significant judgments with respect to the valuation methodologies and assumptions applied by the third-party valuation specialist, including the market and cost approaches. This in turn led to a high degree of auditor judgment and subjectivity in performing procedures and evaluating audit evidence related to management's assumptions. In addition, the audit effort involved the use of internal specialists to assist in performing these procedures and evaluating the audit evidence.
 Our audit procedures related to the estimation of the fair value of the acquired property and equipment included the following procedures, among others. We tested the effectiveness of controls relating to management's review of the valuation methodologies and assumptions applied by the third-party valuation specialist. In addition to testing the effectiveness of controls, we also performed the following:

 • Utilized an internal valuation specialist to evaluate:

 the qualifications of the third-party valuation specialist engaged by the Partnership based on their credentials and experience,
 the process used by management to develop the estimate, including valuation methodologies and assumptions used by the third-party valuation specialists and whether they were acceptable for the underlying assets and applied correctly,
 the useful lives utilized by the third-party valuation specialist by comparing to industry standards and estimates,
 the appropriateness of the replacement cost, by confirming the inputs utilized were reasonable for the underlying assets,
 the estimates of fair values for assets which were valued based on comparable market data and the appropriateness of the replacement costs, by performing independent market research and analyses.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (Tabular dollar amounts, except per unit data, are in millions)

 1. Organization and Principles of Consolidation
 As used in this document, the terms "Partnership," "SUN," "we," "us" and "our" should be understood to refer to Sunoco LP and our consolidated subsidiaries, unless the context clearly indicates otherwise.
 We are a Delaware master limited partnership. We are managed by our general partner, Sunoco GP LLC ("General Partner"), which is owned by Energy Transfer LP ("Energy Transfer"). As of December 31, 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.

 2. 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 two primary operating segments: Fuel Distribution and Marketing and All Other, both of which are included as reportable segments. Our Fuel Distribution and Marketing segment sells motor fuel to our All Other segment and external customers. Our All Other segment includes the Partnership's credit card services, franchise royalties and its retail operations in Hawaii and New Jersey.
 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
 Revenue from motor fuel is recognized either at the time fuel is delivered to the customer or at the time of sale. Shipment and delivery of motor fuel generally occurs on the same day. The Partnership charges wholesale customers for third-party transportation costs, which are recorded net in cost of sales. Through Sunoco Retail, our wholly owned corporate subsidiary, we sell motor fuel to customers on a commission agent basis, in which we retain title to inventory, control access to and sale of fuel inventory and recognize revenue at the time the fuel is sold to the end-use customer. In our Fuel Distribution and Marketing segment, we derive additional income from lease income, propane, lubricating oils and other ancillary product and service offerings. In our All Other segment, we derive other income from merchandise, lottery ticket sales, money orders, prepaid phone cards and wireless services, ATM transactions, car washes and other ancillary product and service offerings. We record revenue from other retail transactions on a net commission basis when a product is sold and/or services are rendered.
 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.

 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.

 Fuel Distribution and Marketing Revenue
 The Partnership's Fuel Distribution and Marketing segment earns revenue from the following channels: sales to distributors, sales to dealers, unbranded wholesale revenue, commission agent revenue, non-motor fuel sales and lease income. Motor fuel revenue consists 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 formula price based on 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 an 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.
 Commission agent revenue consists of sales from commission agent agreements between the Partnership and select operators. The Partnership supplies motor fuel to sites operated by commission agents and sells the fuel directly to the end-use customer. In commission agent arrangements, control of the product is transferred at the point in time when the goods are sold to the end-use customer. To reflect the transfer of control, the Partnership recognizes commission agent revenue at the point in time fuel is sold to the end-use customer.
 The Partnership receives lease income from leased or subleased properties. Revenues from leasing arrangements for which we are the lessor are recognized ratably over the term of the underlying lease.
 All Other Revenue
 The Partnership's All Other segment earns revenue from the following channels: motor fuel sales, non-motor fuel sales and lease income. Motor fuel sales consist of fuel sales to consumers at company-operated retail stores. Non-motor fuel sales includes merchandise revenue that comprises the in-store merchandise and food service sales at company-operated retail stores and other revenue that represents a variety of other services within our All Other segment including credit card processing, car washes, lottery, automated teller machines, money orders, prepaid phone cards and wireless services. Revenue from All Other operations 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.

 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:

 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.

 13. 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.

 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.

 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.

 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.

 17. Partners' Capital
 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:

 Allocation of Net Income
 Our Partnership Agreement contains provisions for the allocation of net income and loss to the unitholders. For purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100 % to Energy Transfer.

 The calculation of net income allocated to common unitholders was as follows:

 Class C Units
 The Partnership has outstanding an aggregate of 16,410,780 Class C Units, all of which are held by wholly owned subsidiaries of the Partnership.
 Class C Units (i) are not convertible or exchangeable into Common Units or any other units of the Partnership and are non-redeemable; (ii) are entitled to receive distributions of available cash of the Partnership (other than available cash derived from or attributable to any distribution received by the Partnership from Sunoco Retail, the proceeds of any sale of the membership interests of Sunoco Retail, or any interest or principal payments received by the Partnership with respect to indebtedness of Sunoco Retail or its subsidiaries) at a fixed rate equal to $ 0.8682 per quarter for each Class C Unit outstanding; (iii) do not have the right to vote on any matter except as otherwise required by any non-waivable provision of law; (iv) are not allocated any items of income, gain, loss, deduction or credit attributable to the Partnership's ownership of, or sale or other disposition of, the membership interests of Sunoco Retail, or the Partnership's ownership of any indebtedness of Sunoco Retail or any of its subsidiaries ("Sunoco Retail Items"); (v) will be allocated gross income (other than from Sunoco Retail Items) in an amount equal to the cash distributed to the holders of Class C Units and (vi) will be allocated depreciation, amortization and cost recovery deductions as if the Class C Units were Common Units and 1 % of certain allocations of net termination gain (other than from Sunoco Retail Items).
 Pursuant to the terms described above, these distributions do not have an impact on the Partnership's consolidated cash flows and as such, are excluded from total cash distributions and allocation of limited partners' interest in net income.
 Incentive Distribution Rights
 The following table illustrates the percentage allocations of available cash from operating surplus between our common unitholders and the holder of our IDRs based on the specified target distribution levels, after the payment of distributions to Class C unitholders. The amounts set forth under "marginal percentage interest in distributions" are the percentage interests of our IDR holder and the common unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column "total quarterly distribution per common unit target amount." The percentage interests shown for our common unitholders and our IDR holder for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. Energy Transfer currently owns our IDRs.

 18. 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:

 19. Segment Reporting
 Our consolidated financial statements reflect two reportable segments: Fuel Distribution and Marketing and All Other.
 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.
 Fuel Distribution and Marketing Segment
 Our Fuel Distribution and Marketing segment purchases motor fuel primarily from independent refiners and major oil companies and supplies it to independently-operated dealer stations under long-term supply agreements, distributors and other consumers of motor fuel and Partnership-operated stations included in our All Other segment. Also included in the Fuel Distribution

 and Marketing segment are motor fuel sales to commission agent locations and sales and costs related to processing transmix. We distribute motor fuels across more than 40 states and territories throughout the United States, including Hawaii and Puerto Rico. Sales of fuel from our Fuel Distribution and Marketing segment to Partnership-operated stations included in our All Other segment are delivered at cost plus a profit margin. These amounts are included in intersegment eliminations of motor fuel revenue and motor fuel cost of sales. Also included in our Fuel Distribution and Marketing segment is lease income from properties that we lease or sublease.
 All Other Segment
 All Other segment includes the Partnership's credit card services, franchise royalties and retail operations in Hawaii and New Jersey.
 The following tables present financial information by segment for the years ended December 31, 2023, 2022 and 2021.

 20. 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:
