Explanation of responses 4 footnotes

Footnote F1

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.

Footnote F2

Includes 5,855 shares acquired under the Issuer's employee stock purchase plan on December 31, 2025.

Footnote F3

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.

Footnote F4
