Abpro Holdings delisted from Nasdaq after failing equity standard compliance
On May 28, 2026, the Nasdaq Listing and Hearing Review Council affirmed a decision to delist Abpro Holdings' securities from Nasdaq because the company failed to meet the minimum equity standard requirement under Nasdaq Listing Rule 5550(b)(1) by the February 16, 2026 deadline set by the Nasdaq Hearings Panel on November 10, 2025. The company's common stock (symbol ABP) and public warrants (symbol ABPWW) are expected to continue trading on the OTC Pink Market, though with reduced liquidity, transparency, and increased volatility.
