Explanation of Responses:

Id Content
F1 On August 14, 2024, the reporting person exercised, by net exercise, a previously issued stock option to purchase 35,000 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 903 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 August 13, 2024 of $19.38, and issuing to the reporting person the remaining 34,097 shares of Class A Common Stock.
F2 The option is fully vested and exercisable.
