Id Content
F1 On November 14, 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 1,970 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 11, 2022 of $9.52, and issuing to the reporting person the remaining 35,530 shares of Class A Common Stock.
F2 The option is fully vested and exercisable.
