ACV Auctions shares fall 25.39% after-hours after missing Q3 earnings, slashing guidance, and facing analyst downgrades.

ACV Auctions fell 25.39% in after-hours trading following a combination of bearish developments, including disappointing third-quarter earnings, weak guidance, and a downgrade from BofA Securities. The company reported a GAAP loss of $0.14 per share (double estimates) and cut full-year EBITDA guidance to $57 million, below the $68.56 million expected. Management also projected Q4 revenue of $182 million, 5% below consensus. BofA downgraded ACVA to Underperform with a $6 price target, citing competitive pressures and high investment costs, while Needham and Goldman Sachs also reduced targets. Despite positive news about its Buffalo expansion and job creation, the bearish financial results and analyst actions dominated, triggering the sharp after-hours sell-off.
