Sarepta Therapeutics (SRPT) stock plummeted 6.14% during Monday's intraday trading session, following news that the company filed for a mixed shelf offering of an undisclosed size.

Mixed shelf offerings are typically used by companies to raise capital by selling securities, including common stock, preferred stock, debt securities, and warrants. The potential dilution from a new share issuance often puts downward pressure on a company's stock price, as it reduces the ownership stake and earnings per share for existing shareholders.

While the exact details of Sarepta's offering have not been disclosed, the market reacted negatively to the news, sending the biotech firm's shares down 6.14% on Monday. The stock movement underscores investors' concerns about potential dilution and the company's need for additional funding.
