The reporting person paid the exercise price on a cashless basis, resulting in the Issuer withholding 5,224 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, 2023 of $17.23, and issuing to the reporting person the remaining 174,776 shares of Class A Common Stock.
