Dyne Therapeutics upsizes public offering to raise about $375 million

Why it may matterVerify against the original reporting

Public offerings typically dilute existing holders and can pressure the stock on announcement; the sizable 18.3M share count and optional 2.745M shares increase float. The immediate price reaction often reflects dilution, counterbalanced by perceived funding of clinical programs; historical analogs show mixed short-term moves but clear long-term impact hinges on use of proceeds.
