Explanation of Responses:

Id	Content
F1	Each RSU is the economic equivalent of one share of Class A Common Stock.
F2	Reflects the shares of Class A Common Stock that were surrendered in order to satisfy the reporting person's tax withholding obligation upon the vesting of RSUs.
F3	On March 3, 2025, Mr. Nursey was awarded 4,000 RSUs, each representing the right to receive, following vesting, one share of Class A Common Stock. Twenty percent (20%) of the restricted stock units vests on each of the first two anniversaries of the date of grant and the remaining sixty percent (60%) will vest on the third anniversary of the date of grant, provided that Mr. Nursey remains in the continuous service of the Company or a subsidiary through each such date.
