Abpro Granted Nasdaq Listing Extension to Pursue Compliance and Strategic Objectives

Continued listing reflects progress on turnaround strategy and pipeline advancement


BURLINGTON, Mass., Dec. 09, 2025 (GLOBE NEWSWIRE) -- Abpro Holdings, Inc. (Nasdaq: ABP) (“Abpro” or the “Company”), a biotechnology company advancing next-generation antibody therapies, today announced that it has received formal notification from the Nasdaq Hearings Panel granting the Company an extension to allow additional time to regain full compliance with Nasdaq listing requirements.

“We view this extension as a recognition that our compliance plan merits continued evaluation as we work to stabilize our business and build lasting momentum,” said Miles Suk, Chief Executive Officer and Chairman of Abpro. “We’ve taken decisive steps to position the Company for sustainable growth. With a leaner structure, access to flexible capital, and continued development support for our lead candidate ABP-102 from our partner Celltrion, we are now focused on execution, delivering results for our shareholders and meaningful impact for patients.”

In addition to the reverse stock split which took effect recently on November 3, Abpro’s compliance roadmap includes a market transfer application and planned capital strategy to increase stockholders’ equity to maintain listing compliance. The Company has access to up to $44 million in equity financing, which it may utilize to fund operations and achieve long-term financial milestones.

Strategic Progress and Forward Outlook

  • Cost Optimization: Abpro has achieved an estimated ~60% reduction in operating expenses versus the prior year through disciplined streamlining.
  • Nasdaq Compliance Plan: Reverse stock split completed and plan to increase stockholders’ equity to support ongoing listing requirements.
  • Capital Strategy: Flexible financing resources in place to support operations and key milestones through 2026.
  • Pipeline Momentum: The lead antibody candidate, ABP-102 (developed in partnership with Celltrion), is on track for first-in-human trials in 2026.
  • Platform Innovation: Abpro is advancing its DiversImmune® and MultiMab™ platforms to unlock value through multispecific antibody designs with enhanced selectivity and safety profiles.

“The fundamentals of our science remain strong, and we’re now executing a smarter, more focused operating model,” said Suk. “This extension provides the time needed to continue pursuing our plan and fulfilling the conditions required under our Nasdaq compliance timeline.”
