INTRODUCTION

This Rule 13e-3 Transaction Statement on Schedule 13E-3 (this “Transaction Statement”), together with the exhibits hereto, is being filed with the Securities and Exchange Commission (the “SEC”) pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by (i) DCP Midstream, LP, a Delaware limited partnership (the “Partnership”), (ii) DCP Midstream GP, LP, a Delaware limited partnership and the general partner of the Partnership (the “General Partner”), (iii) DCP Midstream GP, LLC, a Delaware limited liability company and the general partner of the General Partner (“DCP GP LLC”), (iv) DCP Midstream, LLC, a Delaware limited liability company (“DCP Midstream”), (v) Phillips Gas Company LLC, a Delaware limited liability company and the Class A Managing Member of DCP Midstream, (vi) Phillips 66 Project Development Inc., a Delaware corporation and indirect wholly owned subsidiary of Phillips 66 (“PDI”), (vii) Dynamo Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of PDI (“Merger Sub”), (viii) Phillips 66 Company, a Delaware corporation, and (ix) Phillips 66, a Delaware corporation (“Phillips 66”). Collectively, the persons filing this Transaction Statement are referred to as the “filing persons.”

This Transaction Statement relates to the Agreement and Plan of Merger, dated as of January 5, 2023, by and among Phillips 66, PDI, Merger Sub, the Partnership, the General Partner and DCP GP LLC (the “Merger Agreement”). Pursuant to the Merger Agreement, Merger Sub will merge with and into the Partnership, with the Partnership surviving as a Delaware limited partnership (the “Merger”). Under the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each common unit representing a limited partner interest in the Partnership (each, a “Common Unit”) issued and outstanding as of immediately prior to the Effective Time (other than the Sponsor Owned Units, as defined below) (each, a “Public Common Unit”) will be converted into the right to receive $41.75 per Public Common Unit in cash, without interest. The Partnership’s Series B Preferred Units and Series C Preferred Units will be unaffected by the Merger and will remain issued and outstanding immediately following the Merger. The Common Units owned by DCP Midstream and the General Partner (collectively, the “Sponsor Owned Units”) will be unaffected by the Merger and will remain issued and outstanding immediately following the Merger. Under the terms of the Merger Agreement, at the Effective Time, PDI’s ownership interest in Merger Sub will be converted into a number of new Common Units equal to the number of Public Common Units.

On January 5, 2023, the Special Committee (the “Special Committee”) of the Board of Directors of DCP GP LLC (the “GP Board”), consisting entirely of individuals that satisfy the independence and other requirements for service on the Special Committee that are set forth in the Partnership’s Fifth Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”), by unanimous vote, (i) determined that the proposed Merger, on the terms and conditions set forth in the Merger Agreement, is in the best interests of the Partnership and the holders of Common Units other than DCP Midstream, the General Partner, Phillips 66 and each of their respective affiliates (the “Public Unitholders”) and the consideration to be paid to the Public Unitholders is fair to the Public Unitholders, (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger, with such approval constituting “Special Approval” for all purposes of the Partnership Agreement, including Section 7.9(a) thereof, DCP GP LLC’s Amended and Restated Limited Liability Company Agreement, including Section 6.09(a) thereof, and the General Partner’s Amended and Restated Agreement of Limited Partnership, including Section 7.9(a) thereof, (iii) recommended that the GP Board approve the Merger Agreement and the transactions contemplated thereby, including the Merger, and the execution, delivery and performance of the Merger Agreement and the transactions contemplated thereby, including the Merger, and (iv) recommended that the GP Board resolve to direct that the Merger Agreement and the approval of the Merger be submitted to a vote of the holders of Common Units.

Following the receipt of the Special Committee’s determination and approvals and its related recommendations, at a meeting held on January 5, 2023, the GP Board (acting, in part, based upon the receipt of the Special Committee’s determination and approvals and its related recommendations), by unanimous vote, (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of the Partnership and the Public Unitholders, (ii) authorized and approved the execution and delivery of the Merger Agreement and the consummation of the transactions contemplated thereby, including the Merger, on the terms and subject to the conditions set forth in the Merger Agreement, (iii) directed that the approval of the Merger Agreement and the approval of the Merger be submitted to a vote of the holders of Common Units pursuant to Section 14.3 of the Partnership Agreement, and (iv) authorized the holders of Common Units to act by written consent pursuant to Section 13.11 of the Partnership Agreement.

Pursuant to the Partnership Agreement, the approval of the Merger Agreement and the Merger by the Partnership’s limited partners requires the affirmative vote or written consent of a majority of the outstanding Common Units. On January 5, 2023, concurrently with the execution and delivery of the Merger Agreement, DCP Midstream and the General Partner, which together owned 56.5% of the Common Units issued and outstanding as of such date, delivered a written consent to the General Partner approving the Merger Agreement and the transactions contemplated thereby, including the Merger.

Completion of the Merger is subject to satisfaction or waiver of certain customary conditions.

Concurrently with the filing of this Transaction Statement, the Partnership is filing a preliminary information statement on Schedule 14C (the “Information Statement”).
