Longeveron® Announces Third Quarter 2025 Financial Results and Provides Business Update

MIAMI, November 4, 2025 -- Longeveron Inc. (NASDAQ: LGVN), a clinical stage biotechnology company developing cellular therapies for life-threatening, rare pediatric and chronic aging-related conditions, today reported financial results for the quarter ended September 30, 2025 and provided a business update.

“I am excited to step in to lead Longeveron at this transformational period in both the Company’s history, and our advancement of laromestrocel,” said Than Powell, Interim Chief Executive Officer of Longeveron. “Longeveron has made significant progress advancing three stem cell therapy programs, with each step getting us closer to treating patients with life altering diseases. Our pivotal Phase 2b clinical trial evaluating laromestrocel as a potential treatment for HLHS, a rare pediatric congenital heart defect, is on track to deliver top-line trial results in the third quarter of 2026. If positive, this trial may be the foundation of the Company’s first BLA filing with the U.S. FDA. We believe our research is driving the next wave of medical innovation and Longeveron is well positioned to be an industry leader in stem cell clinical development and commercialization for the benefit of patients and their families.”

Development Programs Update

Longeveron’s investigational therapeutic candidate is laromestrocel (Lomecel-BTM), a proprietary, scalable, allogeneic cellular therapy being evaluated in multiple indications.

Hypoplastic Left Heart Syndrome (HLHS) – a rare pediatric congenital heart birth defect in which the left ventricle (one of the pumping chambers of the heart) is either severely underdeveloped or missing.

Alzheimer’s disease (AD) – a neurodegenerative disorder that leads to progressive memory loss and death and currently has very limited therapeutic options.

Pediatric Dilated Cardiomyopathy (DCM) – a rare pediatric cardiovascular disease in which the muscles in one or more of the heart chambers become enlarged or stretched (dilated), with nearly 40% of children with DCM requiring a heart transplant or dying within two years of diagnosis.
