F1 On November 14, 2024, the reporting person exercised, by net exercise, a previously issued stock option to purchase 270,000 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 7,262 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 13, 2024 of $18.59, and issuing to the reporting person the remaining 262,738 shares of Class A Common Stock.
