(F1)Reflects the grant of restricted stock units ("RSUs") pursuant to the Amended and Restated Antero Resources Corporation 2020 Long-Term Incentive Plan (the "Plan") which vest as to 1/3 of the total amount granted on each of the first three anniversaries of March 7, 2026, generally subject to continued employment through each vesting date.
2. (F2)Includes 117,018 shares of common stock, par value $0.01 per share ("Common Stock") of Antero Resources Corporation (the "Issuer") subject to previously granted RSU awards and 44,662 shares of Common Stock subject to performance share units ("PSUs") in respect of which performance has been certified, in each case, that remain subject to service-based vesting.
3. (F3)In connection with the vesting and settlement of RSUs through the issuance of Common Stock pursuant to the 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 March 6, 2026.
4. (F4)Includes 77,559 shares of Common Stock subject to previously granted RSU awards and 44,662 shares of Common Stock subject to PSU's in respect of which performance has been certified, in each case, that remain subject to service-based vesting.
5. (F5)Each PSU represents a contingent right to receive one share of Common Stock.
6. (F6)Vesting of the PSUs granted on March 7, 2026 is contingent upon the achievement of a performance and service requirement. The performance component measures absolute total shareholder return over each of four performance periods: Performance Period One beginning on March 7, 2026 and ending on March 7, 2027, Performance Period Two beginning on March 7, 2027 and ending on March 7, 2028, Performance Period Three beginning on March 7, 2028 and ending on March 7, 2029, and Performance Period Four beginning on March 7, 2026 and ending on March 7, 2029. Continued service is generally required through the end of each such performance period.
7. (F7)The performance component for one quarter of the PSUs is determined following the completion of each respective performance period and will be settled shortly thereafter, contingent upon continued service through the end of the applicable performance period. 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 shown in column 5.
