Upsized $375M Public Offering Priced
Dyne priced 18.3 million shares at $20.50 per share, a 12% discount to the prior close, raising gross proceeds of $375 million — a 25% increase from the initially filed $300 million offering.
-
Net Proceeds and Cash Runway Extension
Net proceeds are estimated at $352.1 million (or $405.0 million if the underwriters' option is fully exercised). Combined with existing cash and a recent $50 million debt draw, the company expects its cash runway to extend into Q2 2028.
-
Funding Through Key Catalysts
The extended runway carries Dyne past the FDA's Priority Review decision on z-rostudirsen for Duchenne muscular dystrophy, with a PDUFA date expected in late 2026 or early 2027, and supports ongoing Phase 3 and preclinical programs.
-
Dilution Impact
The offering represents approximately 11% dilution to existing shareholders based on the company's ~165 million shares outstanding, though the upsized deal and discount reflect strong institutional demand for the neuromuscular pipeline.
