Explanation of Responses:

( 1 )Represents the number of shares of the Issuer's Class A Common Stock that have been withheld by the Issuer to satisfy its income tax liabilities in connection with the net settlement of restricted stock units. ( 2 )The reported securities are directly held by the YOLO APV Trust (the "APV Trust"), an irrevocable trust with a third-party trustee, of which the reporting person's minor child is beneficiary. The reporting person has the power to remove and replace the APV Trust's trustee. ( 3 )The reported securities are directly held by the YOLO ECV Trust (the "ECV Trust"), an irrevocable trust with a third-party trustee, of which the reporting person's minor child is beneficiary. The reporting person has the power to remove and replace the ECV Trust's trustee. ( 4 )The reported securities are directly held by the reporting person's father-in-law, who is a member of the reporting person's household. The securities were previously reported as being held directly by the Estate of Patricia Shafi. The securities passed to the current owner through inheritance. The reporting person believes this change of ownership is exempt from reporting pursuant to Rule 16a-13, as a change in the form of beneficial ownership without changing the reporting person's pecuniary interest in the shares. The reporting person disclaims beneficial ownership of such securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, except to the extent of his pecuniary interest, if any. ( 5 )Each restricted stock unit represents a contingent right to receive one share of the Issuer's Class A Common Stock upon settlement. ( 6 )The award vested or vests as to 1/16 of the total award on the last day of March, June, September, and December, subject to the reporting person's continued service to the Issuer on each vesting date. The first tranche was scheduled to vest on March 31, 2025, but settlement was deferred pursuant to a duly taken action of the compensation committee of the Issuer's board of directors. ( 7 )These restricted stock units do not expire; they either vest or are cancelled prior to the vesting date.

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