ACV Auctions CFO William Zerella's Stock Dispositions for Tax Withholding

This Form 4 filing reports multiple stock dispositions by William Zerella, Chief Financial Officer of ACV Auctions Inc. On July 1, 2026, Zerella disposed of a total of 21,919 shares of common stock through four separate transactions, all at a price of $7.29 per share. The dispositions were not discretionary sales but rather shares withheld by the company to cover tax liabilities associated with the vesting of time-based restricted stock units previously granted to the executive. Following these transactions, Zerella's remaining ownership decreased from 1,095,181 shares to 1,076,721 shares. The filing indicates these were mandatory tax withholding events rather than voluntary sales by the reporting person.
