Id Content
F1 On May 14, 2024, the reporting person exercised, by net exercise, a previously issued stock option to purchase 180,000 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 3,910 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 May 13, 2024 of $23.02, and issuing to the reporting person the remaining 176,090 shares of Class A Common Stock.
F2 The option is fully vested and exercisable.
