Private placement led by Coastlands Capital with participation from Janus Henderson Investors and other healthcare focused funds
Initial proceeds extend cash runway into 4Q26, past the anticipated pivotal Phase 2b ELPIS II clinical trial 3Q26 topline data readout

MIAMI, March 11, 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 announced the closing of its previously announced private placement for up to approximately $30 million in gross proceeds, priced at-the-market under Nasdaq rules. The net proceeds from the initial tranche of the financing are expected to fund the Company's current operating plans into the fourth quarter of 2026, past the anticipated pivotal Phase 2b ELPIS II clinical trial 3Q26 topline data readout.

The private placement was led by Coastlands Capital, with participation from Janus Henderson Investors, along with Logos Capital and Kalehua Capital, for total gross proceeds in the initial closing of approximately $15 million.

H.C. Wainwright & Co. acted as the exclusive placement agent for the private placement.

At the initial closing, the Company issued 6,013,384 shares of its Class A common stock at a purchase price of $0.52 per share and, in lieu of Class A common stock, shares of the Company's Series A Non-Voting Convertible Preferred Stock (the "Preferred Shares"), convertible into an aggregate of 22,832,770 shares of Class A common stock, at a purchase price $1,000 for each Preferred Share. The Preferred Shares have a conversion price of $0.52 per share and are immediately convertible upon issuance. The Company will be eligible to receive up to an additional approximately $15 million in gross proceeds in exchange for shares of Class A common stock and Preferred Shares, subject to achieving certain milestone-driven conditions related to the results of the Company's Phase 2b ELPIS II clinical trial in HLHS and share price.

Additionally, at the initial closing, the Company agreed to sell to the investors an interest in 50% of proceeds received (after deducting necessary, documented third-party fees or charges) from the potential future sale of a Rare Pediatric Disease Priority Review Voucher, to the extent received from the U.S. FDA in connection with the Company's laromestrocel program for HLHS.

The Company intends to use the net proceeds from the financing, together with its existing cash and cash equivalents, for funding for its ongoing clinical and regulatory development of laromestrocel, working capital and other general corporate purposes. Based on current operating plans, the Company expects that its cash and cash equivalents, excluding the net proceeds from the closing of the second tranche, will fund operations into the fourth quarter of 2026.

The offer and sale of the foregoing securities was made in a private placement pursuant to an exemption under the Securities Act of 1933, as amended (the "Securities Act"), and the securities have not been registered under the Securities Act or applicable state securities laws. The securities may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws.

Buchanan Ingersoll & Rooney PC served as counsel to the Company for the private placement.
