Why DYN Shares Are Down 10% After-Hours? Day After An FDA Win, Another Announcement Rocks Stock
Dyne Therapeutics (DYN) shares dropped 10% after-hours on plans to raise $300M via a stock offering. This follows FDA acceptance of its z-rostudirsen application for Duchenne muscular dystrophy, with a decision expected by January 2027. The company aims to use proceeds for clinical development and commercial infrastructure. DYN stock is up 22% year-to-date.
