Represents the weighted average of the shares sold. The prices of the shares sold pursuant to the transactions range from $0.32 to $0.328 per share. The Reporting Person, upon request, will provide the Securities and Exchange Commission staff, the issuer or the security holder of the issuer full information regarding the number of shares sold at each separate price. The reported shares were sold solely to cover the Reporting Person's tax liability associated with the restricted stock units that vested on December 21, 2025. These sales were made pursuant to an irrevocable election by the Reporting Person to satisfy tax withholding obligations through "sell to cover" transactions and do not represent discretionary trades by the Reporting Person. | The Reporting Person is a trustee of this trust. The Reporting Person disclaims beneficial ownership of the securities held by this trust except to the extent of his respective pecuniary interest therein. | These options are fully vested and exercisable. | The Restricted Stock Units ("RSUs") convert to Class A Common Stock on a one-for-one basis. | These RSUs will vest on December 21, 2025. | The shares of Class B Common Stock are convertible into shares of Class A Common Stock at the option of the Reporting Person and will be automatically converted upon (i) a transfer by the Reporting Person (other than a permitted transfer) or (ii) the first trading day after the seventh anniversary date of the Closing Date (December 21, 2023). The Reporting Person previously reported the grant of a restricted Class B Common Stock award in the amount of 915,033 shares of Class B Common Stock. However, subsequent to the grant date, it was determined that the issuance of shares of Class B Common Stock underlying such award was not authorized in accordance with the Company's charter and such shares will not be issued pursuant to such grant. As a result, the Class B Common Stock underlying the award has been removed from this Form 4.
