Explanation of Responses:

( 1 )Received in exchange for 38,856 common units representing limited partnership interests ("AMLP Common Units") of Antero Midstream Partners LP ("AMLP") pursuant to the Simplification Agreement (the "Simplification Agreement"), dated as of October 9, 2018, by and among the Issuer, AMLP and certain of their affiliates. Pursuant to the Simplification Agreement, holders of AMLP Common Units (other than Antero Resources Corporation) received, in exchange for each AMLP Common Unit held, (i) $3.415 in cash without interest and 1.6350 shares of common stock of the Issuer, (ii) 1.8926 shares of common stock of the Issuer, or (iii) $10.1364 in cash and 1.1279 shares of common stock of the Issuer. ( 2 )This amendment corrects the Reporting Person's Form 4 filed on March 14, 2019 (the "Original Filing"), to revise the row set forth above. In the Reporting Person's Original Filing, 43,825 shares of common stock of the Issuer were reported as acquired by the Reporting Person, rather than correctly stating that 46,869 shares of common stock of the Issuer were acquired by the Reporting Person. The number of shares included in column 5 of this amendment reflects the number of shares owned by the Reporting Person as a result of the transaction reported in this row. It does not give effect to transactions reported on any succeeding line in the Original Filing.

Remarks: Mr. Schopp is the Chief Administrative Officer, Regional Senior Vice President and Treasurer of the Issuer.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
