Soligenix, Inc. (NASDAQ: SNGX), a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need, announced today that it intends to effect a reverse stock split of its common stock at a ratio of 1 post-split share for every 16 pre-split shares.

Stockholders holding shares through a brokerage account will have their shares automatically adjusted to reflect the 1-for-16 reverse stock split. It is not necessary for stockholders holding shares of the Company’s common stock in certificated form to exchange their existing stock certificates for new stock certificates of the Company in connection with the reverse stock split, although stockholders may do so if they wish.
