Abpro Holdings, Inc. 8-K

What Happened

• On May 28, 2026, Abpro Holdings, Inc. (ABPO) announced that the Nasdaq Listing and Hearing Review Council reaffirmed the Nasdaq Hearings Panel's decision to delist the company's securities because the company did not meet the minimum equity standard under Nasdaq Listing Rule 5550(b)(1).
• The Panel had previously required the company to demonstrate compliance by February 16, 2026 (Panel decision dated November 10, 2025). Nasdaq may soon file a Form 25 with the SEC to delist and deregister the securities under Section 12(b) of the Exchange Act.
• After suspension on Nasdaq, the company expects its common stock (symbol ABP) and public warrants (symbol ABPWW) may be eligible for quotation on the OTC Pink Market, but provides no assurance that broker-dealers will make markets or that liquidity and pricing will be maintained.

Key Details

• Notice date from Nasdaq Council: May 28, 2026 (Item 3.01 filing).
• Original Nasdaq Panel decision: November 10, 2025; compliance deadline: February 16, 2026 (minimum equity standard under Rule 5550(b)(1)).
• Nasdaq may file Form 25 to delist and deregister the securities; company expects OTC Pink quotation under symbols ABP and ABPWW after suspension.
• Company warns OTC Pink trading may have limited information, reduced transparency, lower liquidity, and greater volatility; no assurance broker-dealers will make markets.

Why It Matters

• Delisting from Nasdaq can materially reduce the ease of buying and selling the stock and warrants: trading on OTC Pink typically has less liquidity, wider spreads, and fewer investor protections.
• Potential deregistration under Section 12(b) could change reporting and regulatory dynamics; investors should monitor future SEC filings, company updates, and brokerage notices for how trading and reporting will be affected.
• This is a material corporate action for retail shareholders and warrant holders because it directly affects where and how the securities trade and the likely liquidity and visibility of the securities.
