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 May 21, 2019, certain funds affiliated with Warburg Pincus LLC sold 15,000,000 shares of common stock of Antero Midstream Corporation.  Separately, also on May 21, 2019, certain funds affiliated with Yorktown Partners, LLC sold 4,000,000 shares of common stock of Antero Midstream Corporation.

Item 5. Interest in Securities of the Issuer.

This Item 5 shall be deemed to amend and restate Item 5 to the Original Schedule 13D in its entirety.

The aggregate number and percentage of Shares beneficially owned by each Reporting Person and, for each Reporting Person, the number of Shares as to which there is sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition, are set forth on rows 7 through 11 and row 13 of the cover pages of this Schedule 13D and are incorporated herein by reference.

As a result of the Stockholders’ Agreement (as defined below), the Reporting Persons, the Warburg Entities and the Yorktown Entities (collectively, the “Stockholders’ Agreement Parties”) may be deemed to have formed a Section 13(d) group. If the Stockholders’ Agreement Parties are deemed to have formed a Section 13(d) group, such group may be deemed to beneficially own an aggregate of 208,287,026 Shares for the purpose of Rule 13d-3 under the Act, which would constitute approximately 41.1% of the issued and outstanding Shares and total voting power of the Issuer as of immediately following the consummation of the Transactions. The Yorktown Entities have filed a separate Schedule 13D with respect to their interests and Messrs. Rady and Warren and AR Sub have filed a separate Schedule 13D with respect to their interests. Each of the Stockholders’ Agreement Parties disclaims beneficial ownership of Shares owned by the other Stockholders’ Agreement Parties except to the extent of its pecuniary interest therein.

Each of the Other Persons listed below has the following beneficial ownership of Shares (percentages are based on 506,847,308 Shares outstanding as of March 31, 2019):

i.     Yorktown V is the record owner of 1,392,602 Shares of the Issuer, representing 0.27% of the outstanding Shares of the Issuer. Because Yorktown V Company is the sole general partner of Yorktown V, it may be deemed to beneficially own 1,392,602 Shares of the Issuer based on its relationship with Yorktown V. Yorktown V Company disclaims beneficial ownership of these Shares except to the extent of its pecuniary interest therein. Yorktown VI is the record owner of 1,463,246 Shares of the Issuer, representing 0.29% of the outstanding Shares of the Issuer. Because Yorktown VI Company is the sole general partner of Yorktown VI, it may be deemed to beneficially own 1,463,246 Shares of the Issuer based on its relationship with Yorktown VI. Because Yorktown VI Associates is the sole general partner of Yorktown VI Company, it may be deemed to beneficially own 1,463,246 Shares of the Issuer based on its relationship with Yorktown VI Company. Yorktown VI Company and Yorktown VI Associates disclaim beneficial ownership of these Shares except to the extent of their pecuniary interest therein. Yorktown VII is the record owner of 3,412,464 Shares of the Issuer, representing 0.67% of the outstanding Shares of the Issuer. Because Yorktown VII Company is the sole general partner of Yorktown VII, it may be deemed to beneficially own 3,412,464 Shares of the Issuer based on its relationship with Yorktown VII Company. Because Yorktown VII Associates is the sole general partner of Yorktown VII Company, it may be deemed to beneficially own 3,412,464 Shares of the Issuer based on its relationship with Yorktown VII. Yorktown VII Company and Yorktown VII Associates disclaim beneficial ownership of these Shares except to the extent of their pecuniary interest therein. Yorktown VIII is the record owner of 5,266,099 Shares of the Issuer, representing 1.04% of the outstanding Shares of the Issuer. Because Yorktown VIII Company is the sole general partner of Yorktown VIII, it may be deemed to beneficially own 5,266,099 Shares of the Issuer based on its relationship with Yorktown VIII. Because Yorktown VIII Associates is the sole general partner of Yorktown VIII Company, it may be deemed to beneficially own 5,266,099 Shares of the Issuer based on its relationship with Yorktown VIII Company. Yorktown VIII Company and Yorktown VIII Associates disclaim beneficial ownership of these Shares except to the extent of their pecuniary interest therein.

13

ii.   Paul M. Rady is the record owner of 9,634,883 Shares of the Issuer, representing 1.9% of the outstanding Shares of the Issuer. Because Mr. Rady owns a 3.68% limited liability company interest in Mockingbird Investment LLC (“Mockingbird”), and a trust under his control owns the remaining 96.32% in Mockingbird, he may be deemed to beneficially own an additional 19,180,821 Shares of the Issuer owned of record by Mockingbird based on his relationship with Mockingbird. Mr. Rady disclaims beneficial ownership of these Shares except to the extent of his pecuniary interest therein.

iii.   Glen C. Warren, Jr. is the record owner of 16,860,517 Shares of the Issuer, representing 3.3% of the outstanding Shares of the Issuer. Because Mr. Warren is the sole member of Canton Investment Holdings LLC (“Canton”), he may be deemed to beneficially own an additional 3,966,804 Shares of the Issuer owned of record by Canton based on his relationship with Canton. Mr. Warren disclaims beneficial ownership of these Shares except to the extent of his pecuniary interest therein.

iv.   Antero Subsidiary Holdings LLC is the record owner of 107,000,001 Shares of the Issuer, representing 21.1% of the outstanding Shares of the Issuer. Because Antero Resources is the sole member of AR Sub, Antero Resources may be deemed to beneficially own all Shares of the Issuer owned by AR Sub based on its relationship with AR Sub. Antero Resources disclaims beneficial ownership of these Shares except to the extent of its pecuniary interest therein.

Information with respect to each of the Reporting Persons is given solely by such Reporting Person. No Reporting Person has responsibility for the accuracy or completeness of information supplied by another Reporting Person or the Other Persons. Information with respect to each of Other Persons is based on information provided to the Reporting Persons by the Other Persons.

On May 21, 2019, WP VIII sold 14,536,517 Shares, WP VIII CV I sold 421,348 Shares and WP-WPVIII Investors sold 42,135 Shares, each such transaction on the open market and at a price of $12.61 per Share. Separately, on May 21, 2019, Yorktown V sold 483,200 Shares, Yorktown VI sold 507,600 Shares, Yorktown VII sold 1,183,600 Shares and Yorktown VIII sold 1,825,600 Shares, each such transaction on the open market and at a price of $12.61 per Share.

On April 15, 2019, Messrs. Rady and Warren received 37,108 Shares and 24,739 Shares, respectively, upon vesting and settlement of outstanding restricted stock units pursuant to the Antero Midstream Corporation Long-Term Incentive Plan, in each case net of Shares the Issuer withheld to satisfy their respective tax withholding obligations. Except as described in this Schedule 13D, including the Transaction, none of the Reporting Persons has effected any transactions in the Shares during the past 60 days.

Except as set forth in this Item 5 and for persons referred to in Item 2 above, no person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares that may be deemed to be beneficially owned by the Reporting Persons or the Other Persons.
