Explanation of Responses:

Id Content
F1 On November 14, 2023, 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 1,016 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 November 14, 2023 of $17.23, and issuing to the reporting person the remaining 33,984 shares of Class A Common Stock.
F2 The option is fully vested and exercisable.
