(1)	On June 10, 2026, the reporting person filed a Form 4 (the "Original Form") which inadvertently used the "S" code in Column 3 of Table I in connection with the disposal of certain shares of the Issuer's Class A common stock (the "Shares") on June 8, 2026. The Shares were in fact withheld by the Issuer to satisfy tax withholding obligations in connection a vesting event in a transaction approved in accordance with Rule 16b-3 of the Securities Exchange Act of 1934, as amended. Footnote 1 to the Original Form correctly described the transaction as "shares withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting of restricted stock units." Accordingly, the reporting person is hereby amending the Original Form to correctly show the "F" code in Column 3 of Table I. The information set forth in the Original Form was correct in all other respects.
(2)	Represents shares withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting of restricted stock units.
