MIAMI, Aug. 12, 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 June 30, 2026 and provided a business update.

“Longeveron is approaching a series of potentially transformative milestones across our four stem cell therapy development programs that have the potential to redefine the trajectory of our business,” said Stephen H. Willard, Chief Executive Officer of Longeveron. “Our approach to stem cell therapy development has garnered external recognition and validation with positive clinical data having been published in Nature Medicine and Cell Stem Cell and also serving as the foundation for our selection as a Finalist for the XPRIZE Healthspan competition out of over 600 projects submitted worldwide. We are rapidly approaching the September top line data readout of our ELPIS II Phase 2b clinical trial evaluating laromestrocel in HLHS and look forward to sharing those results.”

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 September 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 clinical trial and upcoming data readout.
• Also in May, the Company announced that the independent Data Monitoring Committee (DMC) completed its final prespecified data review for ELPIS II Phase 2b clinical trial (ELPIS II). The DMC performed a risk-benefit assessment, indicated no safety concerns, and approved the study to continue as designed to completion.
• 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.

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.

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

• In July, additional analysis of data from the Phase 2a clinical trial evaluating laromestrocel in mild AD was presented in a Poster Presentation at the 2026 Alzheimer’s Association International Conference^® (AAIC^®). The data indicated that laromestrocel reduced neuroinflammation in patients with mild Alzheimer’s disease.
• 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 potential BLA submission for laromestrocel in Alzheimer’s disease held in March 2025 with tentative 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.

Aging-related Frailty (AF) – a chronic condition driven by systemic physiologic decline, characterized by reduced reserve and resilience across multiple organ systems with common features including weakness, fatigue, weight loss, slowness and reduced activity. No FDA-approved therapies currently exist.

• Laromestrocel data from its Phase 2b clinical trial in Aging-related Frailty were published in Cell Stem Cell in February 2026.
• The Phase 2b results indicated that intravenous laromestrocel improved the physical condition of patients with age-related clinical frailty after nine months, compared to placebo.

Corporate Updates

• In April, the Company announced that the China National Intellectual Property Administration 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 May, the Company issued a CEO Letter to Shareholders highlighting corporate strategy, strategic partnering approach and 2026 key priorities.
• In June, the Company participated in the BIO International Convention. Members of the senior management team hosted meetings to explore potential partnership and strategic opportunities for the Company’s four stem cell development programs.
• In June, the Company announced that it has been granted Small or Medium-sized Enterprise (SME) status by the European Medicines Agency (EMA). The SME program is an initiative by the EMA to address the particular needs of small and medium size companies developing medicinal products in Europe. Companies that are granted SME designation are able to seek scientific advice, protocol assistance, and other information and training from dedicated EMA personnel during the clinical development process. Companies with this designation can engage in early dialogue with the EMA multidisciplinary team and discuss regulatory strategy with the goal of mitigating delay and accelerating patient access to lifesaving treatments.
• On August 11, 2026, the Company announced that it has been selected as a Finalist Team in the XPRIZE Healthspan global competition, a seven-year, $101 million global competition to identify therapeutic approaches to increase human healthspan. As a result, the Company will receive a $1.0 million Milestone 2 Award to be used towards the future clinical trial required in accordance with the XPRIZE competition rules, with the opportunity to compete for the XPRIZE Grand Prize of up to $81 million, subject to the successful completion of the required clinical trial and financing thereof.

2026 Second Quarter Summary Financial Results

• Revenues, Cost of Revenues and Gross Profit: Revenues for each of the three-month periods ended June 30, 2026 and June 30, 2025 was $0.3 million. 2026 revenues decreased by $29,000, or 10%, when compared to 2025, primarily due to the absence of contract manufacturing revenue.

  Clinical trial revenue, which is derived from The Bahamas Registry Trial, for each of the three-month periods ended June 30, 2026 and June 30, 2025 was $0.3 million. Contract manufacturing revenues for the three months ended June 30, 2026 and 2025, were $0 and $18,000, respectively. This decrease of $18,000, or 100%, when compared to the same period in 2025, was driven by the absence of any additional contract manufacturing services from our third-party client.

  Related cost of revenues were $0.1 million and $0.2 million for the three months ended June 30, 2026 and 2025, respectively. This resulted in a gross profit of approximately $0.2 million for the three months ended June 30, 2026, an increase of $36,000, or 25%, when compared to 2025.

• General and Administrative Expenses: General and administrative expenses for the three months ended June 30, 2026 were $3.2 million, compared to $2.6 million for the same period in 2025. The increase of $0.6 million, or 23%, was primarily due to a $0.4 million increase in legal spend and a $0.2 million increase in personnel-related costs.
• Research and Development Expenses: Research and development expenses were $3.2 million for the three months ended June 30, 2026, compared to $3.0 million for the same period in 2025. The increase of $0.2 million, or 7%, was due to higher clinical trial expenses to support the ELPIS II top-line results expected in September 2026.
• Other Income: Other income for the three months ended June 30, 2026 was $0.1 million, primarily consisting of interest earned on money market funds. Other income for the three months ended June 30, 2025, was $0.4 million, primarily consisting of $250,000 received as a recipient of a Milestone 1 Award in the XPRIZE Healthspan competition and $0.1 million of interest earned on money market funds.
• Net Loss: Net loss was $6.1 million for the three months ended June 30, 2026, compared to $5.0 million for the three months ended June 30, 2025. The increase of $1.1 million, or 22%, was due to the factors outlined above.
• Cash and cash equivalents: As of June 30, 2026, the Company had cash and cash equivalents of $10.1 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.
