Regulation FD Disclosure (Form 8-K)

Item 7.01. Regulation FD Disclosure.

On September 10, 2025, ACV Auctions Inc. (the "Company") was notified that a customer of its wholly-owned subsidiary, ACV Capital LLC ("ACV Capital"), filed for Chapter 7 bankruptcy protection (the "Bankruptcy Filing"). ACV Capital previously entered into a floorplan loan agreement under which it provides a line of credit to the customer. There was approximately $18 million aggregate principal amount outstanding under the line of credit at the time of the Bankruptcy Filing.

While the borrowings under the facility are secured by vehicles, the Company continues to assess the status and valuation of the collateral and any necessary provision for doubtful receivables relating to these loans. As a result, the Company is unable to determine at this time the amount of losses it expects to incur and the impact on its financial results from the customer's bankruptcy. The Company plans to pursue all available remedies to protect its interests.

The information furnished under this Item 7.01 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, or subject to the liabilities of that section. The information shall not be deemed incorporated by reference into any other filing with the Securities and Exchange Commission, or the SEC, made by the Company, regardless of any general incorporation language in such filing.
