9. Share-Based Compensation

The Compensation Committee of the Board has approved the grant of non-qualified stock options, restricted stock units (“RSUs”), and shares of common stock to certain employees, non-employees and members of the Board under the ARKO Corp. 2020 Incentive Compensation Plan (as amended, the “Plan”). At the Company’s 2024 annual meeting of stockholders held on June 6, 2024, the Company’s stockholders approved an increase in the total number of shares of common stock authorized for issuance under the Plan from 12.4 million shares to 23.8 million shares. Stock options granted under the Plan expire no later than ten years from the date of grant and the exercise price may not be less than the fair market value of the underlying shares on the date of grant. Vesting periods are assigned to stock options and RSUs on a grant-by-grant basis at the discretion of the Board. The Company issues new shares of common stock upon exercise of stock options and vesting of RSUs.

Additionally, a non-employee director may receive RSUs in lieu of up to 100% of his or her cash fees, which vest immediately and will be settled in common stock upon the director’s departure from the Board or an earlier change in control of the Company.

Stock Options

During the six months ended June 30, 2024, 447 thousand stock options vested. There was no other activity related to stock options during the six months ended June 30, 2024.

As of June 30, 2024, total unrecognized compensation cost related to unvested stock options was approximately $1.0 million, which is expected to be recognized over a weighted average period of approximately 1.4 years.

Restricted Stock Units

During the six months ended June 30, 2024, 186,982 RSUs were issued to non-employee directors. These awards are included in the table above under both Granted and Released RSUs. In addition to the Nonvested RSUs shown in the table above, there were 440,532 and 303,850 RSUs issued to non-employee directors outstanding as of June 30, 2024 and December 31, 2023, respectively.

The fair value of RSUs released during the six months ended June 30, 2024 was approximately $12.0 million.

During the six months ended June 30, 2024, the Company granted 2,021,193 performance-based RSUs (“PSUs”), which, subject to achieving certain performance criteria, could result in the issuance of up to 3,031,790 shares of common stock (representing 150% of the number of PSUs granted). The PSUs were awarded to certain members of senior management and cliff vest at the end of a three-year period, subject to the achievement of specific performance criteria measured over such period. The number of PSUs that will ultimately vest is contingent upon the recipient continuing to be in the continuous service of the Company and related entities through the last day of the performance period and a certification by the Compensation Committee of the Board that the applicable performance criteria have been met. The Company assesses the probability of achieving the performance criteria on a quarterly basis. In the first quarter of 2024, the Compensation Committee of the Board approved the performance criteria for the performance period ended December 31, 2023 such that the percentage of PSUs that vested with respect to the target amount for the 2021 PSU grants was 100%. In the second quarter of 2024, the number of PSUs was adjusted for the probability of achieving the performance criteria, resulting in the recording of a reduction of expense of approximately $1.9 million in the three and six months ended June 30, 2024 based on the grant date fair value.

As of June 30, 2024, total unrecognized compensation cost related to RSUs and PSUs was approximately $22.6 million, which is expected to be recognized over a weighted average period of approximately 2.1 years.
