ZERELLA WILLIAM 4

What Happened
William Zerella, Chief Financial Officer of ACV Auctions (ACVA), received a grant of 276,276 restricted stock units (RSUs) on 2026-04-01 (reported on Form 4). The RSUs were granted at $0.00 (typical for RSU awards) and will vest over time. On the same date the company withheld a total of 12,860 shares to cover tax liabilities related to prior RSU vesting; those withholdings are reported as dispositions (code F) with imputed cash values of $4.27 per share (totaling $54,912).

Key Details

• Transaction date: 2026-04-01; Form 4 filed: 2026-04-03 (appears timely).
• Grant: 276,276 RSUs (code A) at $0.00; vesting in 12 substantially equal quarterly installments beginning July 1, 2026, subject to continued service.
• Tax withholding (code F): 4,919 shares ($21,004), 4,482 shares ($19,138), and 3,459 shares ($14,770) — total 12,860 shares withheld (~$54,912). These withholdings were to cover tax liability and are not discretionary sales.
• Shares owned after transaction: Not disclosed in the filing.
• Footnotes: F1 describes the RSU award and vesting schedule; F2 states the withheld shares were retained by the issuer to satisfy tax obligations (not an open-market sale).

Context
The primary action is an RSU grant (a non‑cash compensation award) that vests over time; this is different from an immediate market purchase or open‑market sale. The tax-withholding entries reflect routine employer withholding when RSUs vest and do not necessarily indicate a decision by the insider to sell shares.
