Footnotes

F1: Each performance share unit ("PSU") represented a contingent right to receive one share of common stock ("Common Stock") of Antero Midstream Corporation (the "Issuer"). On February 24, 2026, the Compensation Committee of the Issuer certified performance and authorized settlement with respect to PSUs originally granted on April 15, 2023, which vested based on the Issuer's return on invested capital over a three year period.

F2: Includes 457,904 shares of Common Stock subject to previously granted restricted stock unit awards that remain subject to vesting.

F3: In connection with the vesting and settlement of PSUs through the issuance of Common Stock pursuant to the Amended and Restated Antero Midstream Corporation Long Term Incentive Plan, the Issuer withheld Common Stock that would otherwise have been issued to the Reporting Person to satisfy their tax withholding obligations. The number of shares of Common Stock withheld was determined based on the closing price per share of Common Stock on February 24, 2026.
