Alaunos Therapeutics completes Velaris acquisition and raises $350 million private placement

Alaunos Therapeutics announced the completion of a stock‑for‑stock merger with Velaris Therapeutics on Oct 13 2026. The deal was funded by an oversubscribed private placement of Series C non‑voting convertible preferred stock that generated gross proceeds of approximately $350 million. The financing gives Alaunos a financial runway into 2029 and is expected to support proof‑of‑concept data for Velaris’s lead program VLR199 in 2028. Peter Harwin, a founding partner of Fairmount, will join Alaunos’s board and the conversion of the preferred shares will increase the total common‑share count to about 358.59 million.

The $350 million infusion extends Alaunos’s cash runway to 2029, allowing it to fund multiple clinical milestones, including VLR199 proof‑of‑concept in 2028 (the company says). The board change and share conversion dilute existing shareholders but bring new strategic investors on board, which may affect governance and future financing.
