CUSIP No. 03676B 102

This Amendment No. 2 amends and supplements the Schedule 13D relating to the shares of common stock, par value $0.01 per share (the Shares), issued by Antero Midstream Corporation, a Delaware corporation (the Issuer), filed on March 15, 2019, as amended by Amendment No. 1 thereto filed on May 24, 2019 (the Schedule 13D). On March 12, 2019, the Issuer was formed as a result of the conversion of Antero Midstream GP LP (AMGP) from a limited partnership to a corporation under the laws of the State of Delaware. Capitalized terms used herein without definition shall have the meanings given to such terms in the Schedule 13D.

Item 5.

Interest in Securities of the Issuer.

This Item 5 shall be deemed to amend and restate Item 5 to the 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, the Reporting Persons and the Other Persons (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 188,287,026 Shares for the purpose of Rule 13d-3 under the Act, which would constitute approximately 37.1% of the issued and outstanding Shares and total voting power of the Issuer as of immediately following the consummation of the Transactions. The Warburg 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 Reporting Persons and the Other Persons listed below has the following beneficial ownership of Shares (percentages are based on 506,896,640 Shares outstanding as of September 5, 2019):

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.

ii.

WP X O&G is the record owner of 22,253,508 Shares of the Issuer, representing 4.39% of the outstanding Shares of the Issuer.

iii.

Warburg Pincus X Partners, L.P. is the record owner of 711,929 Shares of the Issuer, representing 0.14% of the outstanding Shares of the Issuer.

iv.

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.


CUSIP No. 03676B 102

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.

vi.

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 September 5, 2019, WP VIII sold 4,032,316 Shares, WP VIII CV I sold 116,879 Shares, WP-WPVIII Investors sold 11,688 Shares, WP X O&G sold 12,580,788 Shares and Warburg Pincus X Partners, L.P. sold 402,481 Shares, each such transaction on the open market and at a price of $6.81 per Share. Separately, on September 5, 2019, Yorktown V sold 1,392,602 Shares and Yorktown VI sold 1,463,246 Shares, each such transaction on the open market and at a price of $6.81 per Share. On September 5, 2019, each of Yorktown V, Yorktown V Company, Yorktown VI, Yorktown VI Company and Yorktown VI Associates ceased to beneficially own Shares of the Issuer.

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.
