Footnotes from the filing
Restricted stock units ("RSUs") granted to the Reporting Person under the Issuer's Amended and Restated 2021 Equity Incentive Plan. Each RSU represents the contingent right to receive one share of Common Stock. The RSUs vest as to 33.3% of the RSUs on the first three anniversaries of January 21, 2026 such that the award is fully vested on January 21, 2029 (with the number of RSUs vesting on each vesting date rounded down to the nearest whole RSU, except with respect to the final vesting date on which all remaining unvested RSUs shall vest), provided that the Reporting Person continues to serve as an employee of or other service provider to the Issuer on each such vesting date.
