ACV Auctions CEO Chamoun George Sells 54,686 Shares for Tax Withholding

ACV Auctions Inc. CEO George Chamoun filed a Form 4 disclosing the sale of 54,686 common shares on July 1, 2026, at $7.29 per share. The transactions were coded as "F" (tax withholding) rather than discretionary sales, with shares being withheld by the company to cover tax liabilities upon the vesting of time-based restricted stock units. Following these transactions, Chamoun's ownership decreased from 3,398,512 shares to 3,365,107 shares. The filing clarifies these were mandatory tax withholding events rather than voluntary sales by the executive. The transactions were executed by Michelle Webb as attorney-in-fact for the CEO.
