MIAMI, May 13, 2026 (GLOBE NEWSWIRE) -- Longeveron Inc. (NASDAQ: LGVN), a clinical stage biotechnology company developing cellular therapy for life-threatening, rare pediatric and chronic aging-related conditions, today reported financial results for the quarter ended March 31, 2026 and provided a business update.

“Earlier this year, we initiated a strategic repositioning of Longeveron designed to maximize shareholder value while maintaining disciplined capital allocation,” said Stephen H. Willard, Chief Executive Officer of Longeveron. “We have transitioned toward a more capital-efficient, asset-light operating model, with an increased focus on securing strategic licensing partnerships for our stem cell therapy laromestrocel in four development programs. Longeveron is approaching a series of potentially transformative milestones across these programs that have the potential to redefine the trajectory of our business, with the first catalyst, top line results from our Phase 2b clinical trial in HLHS, anticipated in August of this year.”

Development Programs
Longeveron’s investigational therapeutic candidate laromestrocel (Lomecel-B®) is 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.

• Topline results from the Phase 2b clinical trial (ELPIS II) evaluating laromestrocel as a potential adjunct therapy for HLHS are anticipated in August 2026.
• In May, the Company announced that the U.S. Food and Drug Administration (FDA) held a Type C meeting in late March 2026 focused on the ELPIS II Phase 2b clinic trial and upcoming data readout.
• ELPIS II is being conducted in collaboration with the National Heart, Lung, and Blood Institute (NHLBI) through grants from the National Institutes of Health (NIH).
• The FDA has granted laromestrocel Orphan Drug designation, Fast Track designation, and Rare Pediatric Disease designation for the treatment of HLHS.
  
  

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

• Laromestrocel data from the Phase 2a clinical trial (CLEAR MIND) linking neuroinflammation to clinical outcomes in patients with mild Alzheimer’s disease were presented at the 18th Clinical Trials on Alzheimer’s Disease Conference (CTAD 2025) held in December 2025.
• Results from the Phase 2a clinical trial (CLEAR MIND), which support the therapeutic potential of laromestrocel in the treatment of mild Alzheimer’s disease and provided evidence-based support for further clinical development, were published in the peer-reviewed journal Nature Medicine in March 2025.
• Positive Type B meeting with FDA regarding pathway to BLA submission for laromestrocel in Alzheimer’s disease held in March 2025 with alignment reached on proposed trial study design, population and endpoints for a single Phase 2/3 clinical trial that, if positive, could be acceptable for BLA submission for Alzheimer’s disease.
• The FDA has granted laromestrocel both Regenerative Medicine Advanced Therapy (RMAT) designation and Fast Track designation for the treatment of mild Alzheimer’s disease.
• The Company is seeking to forge strategic collaborations and/or partnerships for the advancement of laromestrocel in addressing AD.
  
  

Pediatric Dilated Cardiomyopathy (PDCM) – 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 PDCM requiring a heart transplant or dying within two years of diagnosis.

• Longeveron’s Investigational New Drug (IND) application for its stem cell therapy laromestrocel as a potential treatment for PDCM became effective in July 2025. This IND provides for moving directly to a single Phase 2 registrational clinical trial.
• The Company currently anticipates initiation of the Phase 2 clinical trial in 2027, with planning and preparation beginning in 2026.
  
  

Partnering Strategy
Laromestrocel represents a pipeline in a product opportunity that has delivered positive initial results from multiple clinical trials across several indications. Our stem cell therapy development programs address life-threatening conditions in the most vulnerable populations - children and the elderly: Hypoplastic Left Heart Syndrome; Alzheimer’s disease; Pediatric Dilated Cardiomyopathy and Aging-related Frailty (AF). These four initial indications address market opportunities of what we estimate to be approximately ~$1 billion, ~$5+ billion, up to ~$1 billion, and ~$4 billion, respectively. We plan to pursue a robust partnering strategy across our development programs to accelerate potential time to market, increase capital use efficiency and leverage the greater resources of larger organizations.

• HLHS: If the Phase 2b ELPIS II trial in HLHS is successful and the trial results and other available evidence are deemed sufficient by the FDA to support filing a BLA following the readout of the top-line results, then we would intend to pursue a potential BLA filing with the FDA and a commercialization partner.
• AD: We plan to leverage the strength of our Phase 2 data and clarity on the clinical pathway to a potential BLA for AD to engage with potential funding/commercialization partners.
• PDCM: We plan to conduct a single Phase 2 registrational clinical trial in accordance with the Investigational New Drug (IND) application which became effective in July 2025. If this trial is successful, we would then seek to partner the program for further development and potential commercialization.
• AF: Results from our AF Phase 2b clinical, which were published in Cell Stem Cell, further reinforce the strength and credibility of laromestrocel’s clinical data sets and provide an engagement point for discussions with potential strategic partners to further advance this important but underserved development area.
  
  

Longeveron will participate in the BIO International Convention taking place June 22-25, 2026 at the San Diego Convention Center. Stephen Willard, CEO, Dr. Joshua Hare, Founder, CSO and Executive Chairman, and Than Powell, Business Development, will host meetings with global pharmaceutical company executives to explore potential partnership and strategic opportunities for the Company’s four stem cell development programs.

First Quarter Corporate Updates

• In January, the Company announced that the Japan Patent Office granted a patent covering potency assay methods for assessing human mesenchymal stem cells (MSCs) derived from bone marrow, adipose tissue, peripheral blood, a lung, a heart, amniotic fluid, inner organs, an amniotic membrane, an umbilical cord or a placenta or differentiated from induced pluripotent stem cells (IPSCs).
• In February 2026, the Company announced that its Board of Directors appointed Stephen H. Willard as Chief Executive Officer. Mr. Willard has a 30+ year track record of leadership across public and private sectors as CEO of multiple biotechnology and pharmaceutical firms, with a history of delivering significant fundraises and strategic collaborations.
• In February 2026, the Company implemented cash-saving measures to manage cash utilization and extend cash runway.
• In March 2026, Mr. Richard Kender provided notice of his resignation from the Company’s Board of Directors and Audit Committee, effective immediately, due to his assuming the roles of Executive Chairman and Interim CEO of Seres Therapeutics, Inc.
• In March 2026, the Company completed a private placement of up to $30 million; $15 million up front with a milestone-driven potential additional $15 million related to the results of the Company’s Phase 2b ELPIS II clinical trial in HLHS and share price. The private placement was led by Coastlands Capital with participation from Janus Henderson Investors, Logos Capital and Kalehua Capital.
  
  

2026 First Quarter Summary Financial Results

• Revenues, Cost of Revenues and Gross Profit: Revenues for the three months ended March 31, 2026 were $0.4 million and consisted of $0.4 million of clinical trial revenues and $20,000 of contract manufacturing revenues. Revenues for the three months ended March 31, 2025 were $0.4 million and consisted of $0.3 million of clinical trial revenues and $0.1 million of contract manufacturing revenues. Clinical trial revenues for the three months ended March 31, 2026 increased $0.1 million, or 46%, when compared to the same period in 2025, as a result of greater participant demand for our Bahamas Registry Trial. Contract manufacturing revenues for the three months ended March 31, 2026 decreased $0.1 million, or 84%, when compared to the same period in 2025, driven by reduced demand for these services from our third-party client.
  
  Related cost of revenues was $0.1 million in each of the three months ended March 31, 2026 and 2025. This resulted in a gross profit of $0.3 million in each of the three months ended March 31, 2026 and 2025.

• General and Administrative Expenses: General and administrative expenses for the three months ended March 31, 2026 were $2.7 million, compared to $2.9 million for the same period in 2025. The $0.2 million, or 7%, decrease was primarily due to a $0.4 million reduction in personnel and related costs, reflecting lower performance achievement relating to 2025 annual cash incentive bonuses, partially offset by higher legal, accounting and consulting fees.
• Research and Development Expenses: Research and development expenses were $2.3 million for the three months ended March 31, 2026, compared to $2.5 million for the same period in 2025. The $0.2 million, or 8%, decrease was due to lower performance achievement relating to 2025 annual cash incentive bonuses and a $0.2 million non-recurring charge for amortization expense related to patent costs recorded in the 2025 period, partially offset by a year over year increase in personnel and higher clinical spend as we prepare for ELPIS II study results in August.
• Other Income: Other income was $39,000 and $0.2 million for the three months ended March 31, 2026 and 2025, respectively, and consisted of interest earned on money market funds. The decrease in other income of $0.2 million, or 77%, was due to declining cash balance.
• Net Loss: Net loss was $4.7 million for the three months ended March 31, 2026, compared to $5.0 million for the three months ended March 31, 2025. The decrease of $0.3 million, or 6%, was due to the factors outlined above.
• Cash and cash equivalents: As of March 31, 2026, the Company had cash and cash equivalents of $15.8 million. We currently anticipate our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2026, based on our current operating budget and cash flow forecast. Our operating costs will continue to be substantial for the foreseeable future in connection with our ongoing activities. We intend to seek additional financing opportunities, capital raises, as well as non-dilutive funding options to support our operating plans.
