Explanation of Responses:

Id Content
F1 On September 4, 2023, the reporting person exercised, by net exercise, a previously issued stock option to purchase 180,000 shares of Class A Common Stock of the Issuer. The reporting person paid the exercise price on a cashless basis, resulting in the Issuer withholding 4,884 shares of Class A Common Stock for payment of the exercise price, based on the closing price of the Issuer's Class A Common Stock on September 1, 2023 of $18.43, and issuing to the reporting person the remaining 175,116 shares of Class A Common Stock.
F2 The option is fully vested and exercisable.
