(1) In connection with the vesting and settlement of restricted stock units through the issuance of common stock of the Issuer ("Common Stock") pursuant to the Antero Midstream Corporation Long Term Incentive Plan, the Issuer withheld Common Stock that would otherwise have been issued to the Reporting Person to satisfy its tax withholding obligations. The number of shares of Common Stock withheld was determined based on the closing price per share of Common Stock on April 15, 2019.
(2) Includes 66,047 shares of Common Stock subject to previously granted restricted stock unit awards that remain subject to vesting.
(3) Common Stock subject to a Restricted Stock Unit Grant Notice and Restricted Stock Unit Agreement that vest in four equal installments on the first four anniversaries of the grant date.
(4) Represents securities held by Canton Investment Holdings LLC ("Canton"). The Reporting Person is the managing member and 50% owner of Canton. The Reporting Person disclaims beneficial ownership of all securities held by Canton except to the extent of his pecuniary interest therein.
(5) Each performance share unit ("PSU") represents a contingent right to receive one share of common stock of the Issuer.
(6) The PSUs vest on April 15, 2022 based upon the Issuer's achievement of absolute total shareholder return goals. Depending on the level of achievement of such goals, the actual number of PSUs earned could range from 0% to 200% of the target number of PSUs, as shown in columns 5 and 6.
