INTRODUCTION

This Amendment amends and supplements the Schedule 13D relating to the common shares representing limited partnership interests of Antero Midstream GP LP (“AMGP”) that was filed on May 22, 2017 and amended by Amendment No. 1 on June 13, 2017, by Amendment No. 2 on October 16, 2018, by Amendment No. 3 on March 14, 2019, by Amendment No. 4 on May 24, 2019, and by Amendment No. 5 on September 6, 2019 (the “Original Schedule 13D” and, together with this Amendment, the “Schedule 13D”) with the U.S. Securities and Exchange Commission (the “SEC”) by Warburg Pincus Private Equity VIII, L.P., a Delaware limited partnership (“WP VIII” and, together with its two affiliated partnerships, Warburg Pincus Netherlands Private Equity VIII C.V. I, a limited partnership formed under the laws of the Netherlands (“WP VIII CV I”), and WP-WPVIII Investors, L.P., a Delaware limited partnership (“WP-WPVIII Investors”), collectively, the “WP VIII Funds”); Warburg Pincus Private Equity X O&G, L.P., a Delaware limited partnership (“WP X O&G” and, together with its affiliated partnership, Warburg Pincus X Partners, L.P., a Delaware limited partnership, the “WP X O&G Funds”); Warburg Pincus X, L.P., a Delaware limited partnership (“WP X GP”), which is the general partner of each of the WP X O&G Funds; Warburg Pincus X GP L.P., a Delaware limited partnership (“WP X GP LP”), which is the general partner of WP X GP; WPP GP LLC, a Delaware limited liability company (“WPP GP”), which is the general partner of WP X GP LP and WP-WPVIII Investors GP L.P., a Delaware limited partnership (“WP-WPVIII GP”), which is the general partner of WP-WPVIII Investors; Warburg Pincus Partners, L.P., a Delaware limited partnership (“WP Partners”), which is (i) the managing member of WPP GP, and (ii) the general partner of WP VIII and WP VIII CV I; Warburg Pincus Partners GP LLC, a Delaware limited liability company (“WP Partners GP”), which is the general partner of WP Partners; Warburg Pincus & Co., a New York general partnership (“WP”), which is the managing member of WP Partners GP; Warburg Pincus LLC, a New York limited liability company (“WP LLC”), which is the manager of each of the WP VIII Funds and the WP X O&G Funds; and Charles R. Kaye and Joseph P. Landy, who are the Managing General Partners of WP and the Managing Members and Co-Chief Executive Officers of WP LLC and may be deemed to control the Warburg Pincus Entities (as defined below). Each of the WP VIII Funds, the WP X O&G Funds, WP X GP, WP X GP LP, WPP GP, WP Partners, WP Partners GP, WP and WP LLC are collectively referred to herein as the “Warburg Pincus Entities” and, together with Charles R. Kaye and Joseph P. Landy, the “Reporting Persons.” Unless set forth below, all previous Items of the Original Schedule 13D are unchanged. Capitalized terms used but not defined herein shall have the meaning set forth in the Original Schedule 13D.

On November 12, 2019, the WP X O&G Funds sold all remaining shares of common stock of Antero Midstream Corporation owned by them and, as such, each of the Reporting Persons ceased to be the beneficial owners of more than five percent of the common stock of Antero Midstream Corporation pursuant to any deemed Section 13(d) group in connection with that certain Stockholders’ Agreement, dated March 12, 2019 (the “Stockholders’ Agreement”), by and among certain funds affiliated with Warburg Pincus LLC and other stockholders of Antero Midstream Corporation. Consequently, the filing of this Amendment represents the final amendment to the Schedule 13D and constitutes an “exit filing” for each of the Reporting Persons. Separately, also on November 12, 2019, certain investment funds managed by Yorktown Partners, LLC (together with the WP X O&G Funds, the “Selling Stockholders”) sold 3,000,000 shares of common stock of Antero Midstream Corporation.

Item 4 shall be amended to add the following:

On November 12, 2019, the WP X O&G Funds sold all 22,965,437 shares of common stock of Antero Midstream Corporation that they held of record in a registered offering at a price of $6.52 per share pursuant to the Underwriting Agreement, dated November 6, 2019, by and among Antero Midstream Corporation, the Selling Stockholders and Barclays Capital Inc. As a result of the sale, the Reporting Persons disposed of all of their shares of common stock of Antero Midstream Corporation and are no longer subject to the terms of the Stockholders’ Agreement nor part of any deemed Section 13(d) group in connection with the Stockholders’ Agreement.

Item 5 shall be amended and restated as follows:.

(a)-(b) As a result of the transaction disclosed in Item 4 herein, the Reporting Persons no longer own any securities of Antero Midstream Corporation nor have sole or shared power to vote, direct the vote, dispose or direct the disposition with respect to any securities of Antero Midstream Corporation, and therefore their obligation to file further amendments to this statement has terminated.

(c) Except as described in this Schedule 13D, none of the Reporting Persons has effected any transactions in shares of common stock of Antero Midstream Corporation during the past 60 days.

(d) Not applicable.

(e) On November 12, 2019, the WP X O&G Funds sold all remaining shares of common stock of Antero Midstream Corporation owned by them and, as such, each of the Reporting Persons ceased to be the beneficial owners of more than five percent of the common stock of Antero Midstream Corporation pursuant to any deemed Section 13(d) group in connection with the S tockholders’ Agreement.

The information set forth in Item 4 above is hereby incorporated by reference into Item 6.
