Explanation of Responses:

Id Content
F1 This Form 4 is being filed late due to an inadvertent administrative oversight related to the Issuer's migration to a new employee stock administration platform, which delayed the timely reporting of the transaction and was not the result of any error by the Reporting Person.
F2 Represents restricted stock units granted as bonus compensation for fiscal year 2025 pursuant to the Issuer's Third Amended and Restated 2021 Equity Incentive Plan. Each restricted stock unit represents a contingent right to receive one share of the Issuer's Class A Common Stock and vested immediately.
F3 Represents the number of shares withheld to cover the Reporting Person's tax liability in connection with the vesting of certain restricted stock units and does not represent a discretionary sale by the Reporting Person.
