Pulmatrix has registered 490,910 shares of common stock for resale by RCM Eos PIPE HOLDINGS, LLC, an affiliate of Eos SENOLYTIX, Inc. This registration enables the investor to convert their Series B Convertible Preferred Stock and associated dividend shares, which were part of a private placement that closed on April 16, 2026. The potential resale of these shares represents approximately 13% dilution to existing stockholders. While the original private placement provided crucial capital for Pulmatrix, which recently issued a going concern warning and is relying on its merger with Eos SENOLYTIX, this registration creates an overhang of potential selling pressure. The investor is currently restricted from transferring shares until the merger closes or one year from the issuance date.
