SUNOCO LP

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

Introduction

The following unaudited pro forma combined financial statements of Sunoco LP (“SUN”), formerly Susser Petroleum Partners LP, reflects the pro forma impacts of multiple transactions, each of which is described in the following sections. Our unaudited pro forma financial statements as of and for the year ended December 31, 2014, reflect the following transactions:

·                  The previously reported October 1, 2014 acquisition of Mid-Atlantic Convenience Stores, LLC (“MACS”) from Energy Transfer Partners, L.P. (“ETP”), the owner of our general partner and a 42.8% limited partner interest in us, for total consideration consisting of (i) $556 million in cash, subject to adjustment for working capital, and (ii) 3,983,540 of our common units (the “MACS Acquisition”);

·                  The previously reported December 16, 2014, acquisition of Aloha Petroleum, Ltd. (“Aloha”) for cash consideration of $240 million, subject to a post-closing earn-out and certain closing adjustments (the “Aloha Acquisition”); and

·                  The proposed acquisition of a 31.58% interest in Sunoco, LLC from ETP Retail Holdings, LLC (“ETP Retail”), which is wholly owned by ETP, for total consideration consisting of approximately $775.0 million in cash and $40.8 million of our common units, including the proposed issuance of notes in this offering (the “Sunoco LLC Acquisition”).

The historical financial information included in the column entitled “SUN” was derived from the audited consolidated financial statements included in SUN’s Annual Report on Form 10-K for the year ended December 31, 2014. The unaudited pro forma condensed combined statement of operations assumes that the above transactions were consummated as of January 1, 2014. The unaudited pro forma condensed combined balance sheet assumes that the Sunoco LLC Acquisition was completed as of December 31, 2014. The MACS Acquisition and Aloha Acquisition are already reflected in our audited balance sheet as of December 31, 2014. The pro forma results of the MACS Acquisition and Aloha Acquisition were previously provided in our Current Report on Form 8-K/A on March 2, 2015.

MACS Acquisition

On September 25, 2014, SUN entered into a contribution agreement with MACS, ETC M-A Acquisition LLC (“ETC”) and ETP, whereby SUN agreed to acquire all of the issued and outstanding membership interests of MACS from ETC for $556 million in cash, subject to adjustment for working capital, and 3,983,540 SUN common units. SUN initially financed the cash portion of the purchase price by utilizing availability under its revolving credit facility, subsequently raising net proceeds of $405 million from the sale of 9.1 million common units which were used to repay revolver borrowing. The MACS Acquisition was completed on October 1, 2014.

SUN is accounting for the acquisition of MACS as a transfer of net assets between entities under common control. As such, the MACS assets acquired from ETP have been recorded by SUN at ETP’s historic carrying value, and SUN has included the activities of MACS in its 2014 audited financial statements as of the September 1, 2014 date of common control for accounting purposes. Financial statements for MACS were previously provided as attachments 99.2 and 99.3 to our Current Report on Form 8-K/A on October 21, 2014.

Aloha Acquisition

On September 25, 2014, SUN and Susser Petroleum Property Company LLC (“Propco”), a wholly owned subsidiary of SUN, entered into a purchase and sale agreement in which SUN and Propco agreed to acquire all of the issued and outstanding shares of capital stock of Aloha for base consideration of $240 million in cash, subject to a post-closing earn-out and certain closing adjustments. Consummation of the Aloha Acquisition occurred on December 16, 2014. SUN financed the purchase of Aloha by utilizing availability under its revolving credit facility. SUN’s management currently plans to contribute certain assets from Propco to SUN at a future date; however, the impact of this discretionary management action is not included in the accompanying pro forma combined financial information.

The pro forma adjustments reflect a preliminary purchase price allocation. The carrying values of assets and liabilities (excluding intangibles and non-current liabilities) in this preliminary estimate were assumed to approximate their fair values. Our identifiable intangible assets consist primarily of dealer relationships. The amount of goodwill preliminarily recorded represents the excess of our estimated enterprise value over the fair value of our assets and liabilities. The value of certain assets and liabilities are preliminary in nature, and are subject to adjustment as additional information is obtained about the facts and circumstances that existed at the acquisition date. As a result, material adjustments to this preliminary allocation may occur in the future. Management is reviewing the valuation and confirming the results to determine the final purchase price allocation.

Sunoco LLC Acquisition

On March 23, 2015, we entered into a contribution agreement with ETP Retail and ETP to acquire a 31.58% membership interest in Sunoco, LLC, for total consideration of $775 million in cash and $40.8 million of our common units. We will have a 50.1% voting interest in Sunoco, LLC. The Sunoco LLC Acquisition is expected to close in early April 2015.

SUN will account for the Sunoco LLC Acquisition as a transfer of net assets under common control, and therefore will record the acquired assets at ETP’s historic carrying value. Additionally, SUN will recast its historical financial statements to include the operations of Sunoco, LLC as of the September 1, 2014 date of common control for accounting purposes. Because we will have a controlling interest in Sunoco LLC as a result of our 50.1% voting interest, our pro forma financial results and balance sheet reflect the results of Sunoco LLC on a consolidated basis, which means that, except as otherwise indicated, our pro forma financial results and balance sheet reflect 100% of the assets and operations of Sunoco LLC, even though our pro forma economic interest is only 31.58%.

Adjustments for the above-listed transactions are presented in in the following schedules, and further described in the notes to the unaudited pro forma combined financial statements. Certain information normally included in the financial statements prepared in accordance with GAAP has been condensed or omitted in accordance with the rules and regulations of the SEC. The unaudited pro forma combined financial statements and accompanying notes should be read in conjunction with the historical financial statements and related notes thereto.

The unaudited pro forma condensed combined financial statements do not purport to be indicative of the results of operations or financial position that we actually would have achieved if the transactions had been consummated on the dates indicated, nor do they project our results of operations or financial position for any future period or date.
