Filing's footnotes

1. Consists of restricted stock units ("RSUs"). Each RSU represents the right to receive one share of Class A Common Stock upon vesting. The RSUs vest in three equal annual installments beginning on March 1, 2027, subject to the Reporting Person's continued service on each such vesting date.

2. Includes 14,282 shares acquired under the Issuer's employee stock purchase plan on December 31, 2025.

3. The Issuer has adopted a "sell-to-cover" policy to satisfy the tax withholding obligations of the Reporting Person. The sales reported on this Form 4 represent the number of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units. Such sales were automatic and not at the discretion of the Reporting Person.

4. Represents the weighted average sales price per share. The shares sold at prices ranging from $3.575-$3.80 per share. Full information regarding the number of shares sold at each price shall be provided upon request to the staff of the U.S. Securities and Exchange Commission, the Issuer, or a security holder of the Issuer.
