F1 On August 8, 2022, the reporting person exercised, by net exercise, a previously issued stock option to purchase 37,500 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 981 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 5, 2022 of $19.13, and issuing to the reporting person the remaining 36,519 shares of Class A Common Stock.
