Explanation of Responses:

Id	Content
F1	Represents shares of Class A Common Stock of the Issuer sold to satisfy the reporting person's tax withholding obligations, which were incurred in connection with the vesting of restricted stock units. In accordance with company policy, shares are automatically sold to cover such obligations.
F2	The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $6.92 to $7.185, inclusive. The reporting person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the U.S. Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.
F3	Each performance-based restricted stock unit ("PRSU") 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.
F4	On March 28, 2025, the Issuer's compensation committee certified achievement of the first tranche of the PRSU award granted on March 26, 2024 (the "2024 PRSU Award") at the maximum level, resulting in one-third of the 2024 PRSU Award becoming earned at 200% of the target amount granted.
F5	The remaining tranches of the PRSU Award may expire if the relevant performance criteria are not achieved within the applicable performance period for such tranche. The performance period for the second and third tranches ends on March 26, 2026 and 2027, respectively.
