Recent Developments

The Acquisition and Related Transactions

On March 31, 2016, pursuant to the Contribution Agreement dated November 15, 2015 (the “Contribution Agreement”) among us, Sunoco LLC, Sunoco Inc., ETP Retail Holdings, LLC (“ETP Retail”), our general partner and Energy Transfer Partners, L.P. (“ETP”), we completed our acquisition from ETP Retail of (a) 100% of the issued and outstanding membership interests of SUN Retail and (b) 68.42% of the issued and outstanding membership interests of Sunoco LLC (the “Acquisition”). Pursuant to the terms of the Contribution Agreement, ETP has agreed to guarantee all of the obligations of ETP Retail under the Contribution Agreement, and the Acquisition will be effective January 1, 2016.

Immediately prior to the closing, SUN Retail owned all of the retail assets of Sunoco, Inc. (R&M), an indirect wholly owned subsidiary of Sunoco Inc. (“SUN R&M”), including an ethanol plant located in Fulton, New York previously owned by SUN R&M, 100% of the issued and outstanding membership interests in Sunmarks, LLC, and all the retail assets of Atlantic Refining & Marketing Corp., a wholly owned subsidiary of Sunoco Inc. (“Atlantic”). Please see “Business—Business and Operations of SUN Retail” for a more detailed discussion of SUN Retail’s business.

Subject to the terms and conditions of the Contribution Agreement, at the closing of the Acquisition, we paid to ETP Retail approximately $2.207 billion in cash and issued to ETP Retail 5,710,922 common units representing limited partner interests in the Partnership (the “Unit Consideration”). The Unit Consideration was issued and sold to ETP Retail in a private transaction exempt from registration under Section 4(a)(2) of the Securities Act.

In connection with the closing of the Acquisition, the Partnership entered into a $2.035 billion senior secured term loan facility to fund a portion of the cash consideration for the Acquisition. We funded the remaining portion of the cash consideration with borrowings under our revolving credit facility. We intend to use the net proceeds from this notes offering to repay a portion of the borrowings outstanding under the term loan facility. Please read “Description of Other Indebtedness—Term Loan Facility.”

We entered into a guarantee of collection with ETP Retail at the closing of the Acquisition, pursuant to which ETP Retail agreed to provide a limited contingent guarantee of collection with respect to the payment of the principal amount of the term loan facility (the “term loan guarantee”). In addition, each of SUN R&M and Atlantic (collectively, the “Support Providers”), entered into a separate support agreement (collectively, the “Support Agreements”) with us and ETP Retail. Pursuant to the Support Agreements, the applicable Support Provider agreed to provide contingent residual support to ETP Retail with respect to ETP Retail’s obligations under the term loan guarantee, subject to a cap equal, in the case of each of the Support Providers, to the portion of the principal amount of the term loan facility corresponding to the pro rata percentage of the cash consideration distributed to such Support Provider by ETP Retail, as adjusted pursuant to the terms of the applicable Support Agreement. Accordingly, the contingent residual support obligations of SUN R&M and Atlantic are initially limited to 90.4% and 9.6% of the $2.035 billion principal amount of the term loan facility, respectively. In connection with this offering, ETP Retail will provide a limited contingent guarantee of our

obligation to pay the principal on the notes. As a result, we expect the term loan guarantee to be reduced by the amount of the ETP Retail contingent guarantee and for the Support Providers to provide contingent residual support with respect to ETP Retail’s obligations under the term loan guarantee and the ETP Retail contingent guarantee.

Equity Offerings

Simultaneously with the closing of the Acquisition, we completed the sale of 2,263,158 of our common units to Energy Transfer Equity, L.P. (“ETE”) pursuant to that certain common unit purchase agreement dated November 15, 2015, and received $64.5 million of proceeds from such sale (the “ETE Equity Offering”). The proceeds from the ETE Equity Offering were used to repay borrowings under our revolving credit facility. In addition, we previously completed a private placement of 24,052,631 of our common units to certain institutional investors in November 2015 for gross proceeds of approximately $685 million (the “Private Placement”). The proceeds from the Private Placement were used to repay borrowings under the revolving credit facility.

In this offering memorandum, we refer to (i) our entry into the term loan facility, (ii) the consummation of the ETE Equity Offering and the use of the net proceeds therefrom, (iii) the consummation of the Acquisition, including the payment of the cash consideration with borrowings under our term loan facility and revolving credit facility and the issuance of the Unit Consideration and (iv) the consummation of this notes offering and the contemplated use of the net proceeds therefrom, collectively, as the “Transactions.”

Factors Affecting the Quarter Ended March 31, 2016

Wholesale and retail fuel prices are directly related to, and fluctuate with, the price of crude oil. These fuel prices also tend to track rising commodity prices more rapidly than they do falling commodity prices. In addition, wholesale fuel prices typically respond faster to changes in commodity prices than retail fuel prices. As a result, significant increases in the price of crude oil over a short period of time can temporarily reduce retail fuel margins as wholesale fuel prices typically increase faster than retailers are able to pass this increased cost along to customers. In addition, when there is high volatility in crude oil prices, it becomes difficult to forecast margins or predict how wholesale costs and sales price fluctuations will affect our operating results.

Our wholesale or retail fuel margins for the first quarter of 2016, as compared to the first quarter of 2015, may be impacted by the substantial and sudden increase in the price of wholesale fuel, driven by a similar trend in the price of crude oil. For reference, during March 2016, the price of Reformulated Gasoline Blendstock for Oxygen Blending (“RBOB”) gasoline (a market indicator for wholesale fuel cost) and West Texas Intermediate (“WTI”) crude oil increased on a month-to-month basis by 36.2% and 11.4%, respectively, compared to a decrease on a month-to-month basis in the price of RBOB gasoline and WTI crude oil by 6.9% and 4.0%, respectively, during March 2015. Although January and February 2016 experienced comparable fuel margins to the fourth quarter of 2015, fuel margins in March 2016 are likely to be negatively impacted due to the pricing factors outlined above.

In addition to fuel costs, 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 generally increase in the late spring and summer months in the geographic areas in which we operate, increasing the demand for motor fuel. Therefore, the volume of motor fuel that we distribute during the first quarter of our fiscal year is typically lower than the second and third quarters.
