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

On Oct 13 2026 Alaunos Therapeutics finalized a stock‑for‑stock merger with Velaris Therapeutics and simultaneously closed a private placement that generated approximately $350 million in gross proceeds. The financing gives Alaunos a financial runway into 2029 and is intended to fund clinical proof‑of‑concept data for Velaris’s lead program VLR199 in 2028. Peter Harwin, the founding partner of Fairmount, will join Alaunos’s board and, after a planned stockholder vote, the conversion of the preferred shares will increase the company’s common share count to about 358.59 million.

The company says the $350 million infusion will support operations through 2029 and enable key data readouts in 2028, which could de‑risk its cardiopulmonary pipeline (the company’s statement). The conversion of the preferred stock into common shares will dilute existing shareholders to roughly 358.59 million shares (the filing).
