1	Common	Class A Common Stock	2026-06-10	S	D	15,512	$34.10	1,139,676	D	—	—	(F1) Represents the number of shares sold to cover the statutory tax withholding obligations in connection with the vesting of Restricted Stock Units (RSUs) and does not represent a discretionary sale by the Reporting Person. The "Amount" and "Price" reported in this Column 4 reflect the aggregate number and weighted-average price, respectively, of shares sold. (F2) Certain of these securities are RSUs. Each RSU represents a contingent right to receive one share of Class A Common Stock, subject to the applicable vesting schedule and conditions of each RSU. (F3) The Form 4 filed on September 15, 2025 (the "Original Form 4") and the Form 4/A filed on October 17, 2025 (the "Original Form 4/A") erroneously reflected an incorrect vesting schedule. One third (1/3rd) of the RSUs are scheduled to vest on September 10, 2026, and thereafter, one twelfth (1/12th) of the total number of RSUs are scheduled to vest quarterly on the 10th day of the third month of each quarter (March 10, June 10, September 10, December 10), subject to the named executive officer continuing to be a service provider through the applicable vesting date. The Amount of Securities Beneficially Owned Following Reported Transactions represented on the Original Form 4 and the Original Form 4/A was correctly reported.
