ZERELLA WILLIAM 4

What Happened

• William Zerella, Chief Financial Officer of ACV Auctions Inc. (ACVA), had 21,919 shares withheld by the company to cover tax liabilities upon vesting of time‑based restricted stock units. The withholding occurred in four tranches on July 1, 2026, at $7.29 per share, with individual disposals of 3,459; 4,481; 9,060; and 4,919 shares, resulting in proceeds (withheld value) of $25,216; $32,666; $66,047; and $35,860, respectively (combined ≈ $159,789). This was a tax-withholding disposition, not a discretionary open‑market sale.

Context

• This was a tax-withholding event (F code), equivalent to the company retaining shares to satisfy tax obligations when RSUs vest. It is routine and does not necessarily signal the insider’s view of the company’s prospects.
