Why it may matterVerify against the original reporting

Secondary offerings in biotech frequently lead to near-term share dilution and crowding out of existing holders, pressuring the stock on announcement and pricing uncertainty. Historical patterns show immediate price declines around 3-15% depending on size, pricing, and market condition, though longer-term recovery depends on use of proceeds and clinical progress.
