[Form 4] ACV Auctions Inc. Insider Trading Activity

Rhea-AI Filing Summary

ACV Auctions Inc. (ACVA) – Form 4 insider transaction

Vice-President, Corporate Controller & CAO Andrew Peer reported four Rule 16b-3 “F” transactions on 1 Jul 2025. A Code “F” denotes shares withheld by the issuer to satisfy payroll-tax obligations triggered by the vesting of previously granted time-based RSUs; it is not an open-market sale.

• Total shares withheld: 4,134 at an implied price of $16.48, representing tax value of roughly $68k.
• After the transactions, Peer’s direct holding stands at 56,750 common shares, which includes 500 shares bought via the 2021 ESPP (12/1/24-5/31/25 period).
• The company’s Class A designation has been dropped; the security is now simply called “Common Stock,” with no change to shareholder rights.

Because the disposition was automatic for tax withholding, the filing is generally viewed as neutral from a governance or sentiment standpoint. Peer maintains a meaningful equity stake, aligning his incentives with shareholders.

Insights

Senior Securities Analyst

TL;DR: Tax-withholding disposition; no directional signal; insider retains sizable stake.

The Form 4 shows a standard RSU-vesting event. Shares were automatically surrendered to cover withholding taxes, as reflected by the Code “F.” There were no open-market or discretionary sales. Peer's retained holding of 56.8 k shares—worth roughly $0.94 m at the reference price—remains intact, suggesting continued alignment with shareholders. Such filings are routine and carry minimal market impact unless they reveal broader selling patterns, which is not the case here.
