Explanation of Responses:

( 1 )Certain of the shares are subject to forfeiture to the Issuer if underlying vesting conditions are not met. ( 2 )Each performance-based restricted stock unit represents a contingent right to receive one share of the issuer's Class A Common Stock upon the achievement of certain performance criteria and pursuant to the terms of the reporting person's agreement with the Issuer. ( 3 )On March 15, 2024 the reporting person was granted a performance-based restricted stock unit award capable of vesting and settling for up to 40,238 restricted stock units (the "PRSU Award"). Pursuant to the reporting person's agreement with the Issuer, the PRSU Award may vest in four equal tranches, with the vesting and settlement of each tranche being contingent upon the achievement of pre-determined corporate performance milestones. The reported transaction represents the vesting and settlement of the first tranche of the PRSU Award upon the satisfaction of the aforementioned requirements. ( 4 )The remaining tranches of the PRSU Award may expire if the relevant performance criteria are not achieved by January 31, 2028.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
