Tonix Pharmaceuticals Announces Reverse Split of Common Stock

Key Step for Listing on NASDAQ

NEW YORK, NY--(Marketwired - May 01, 2013) -  Tonix Pharmaceuticals Holding Corp. (OTCQBTNXP) ("TONIX" or "the Company"), a specialty pharmaceutical company developing novel treatments for challenging disorders of the central nervous system, including fibromyalgia ("FM") and post-traumatic stress disorder ("PTSD"), announced that on May 1, 2013 (the "Effective Date"), it effected a one (1) for twenty (20) reverse split of its issued and outstanding common stock (the "Reverse Split") as a step toward the Company's intention to have its common stock listed on the NASDAQ Capital Market.

The Company effected the Reverse Split pursuant to an amendment to its Articles of Incorporation filed with the Secretary of State of Nevada on April 26, 2013, which became effective at 9:00 am on May 1, 2013. As of the Effective Date, each 20 shares of issued and outstanding common stock will be converted into one share of common stock. The Company's common stock will trade under a new CUSIP number (890260201). The Company's ticker symbol, "TNXP", will remain unchanged; however, the ticker symbol will be represented as "TNXPD" for 20 trading days commencing on the Effective Date to designate the Reverse Split.

"We view the Reverse Split as an important step in TONIX's corporate development. The maintenance of a minimum closing price of $4.00 for at least 30 of 60 trading days would fulfill the share price requirement for an uplisting to NASDAQ," said Seth Lederman, M.D., Chief Executive Officer of TONIX. "We also highlight the recent exercise of out-of-the-money stock warrants for 38,334 shares of our common stock at an exercise price of $8.00 by members of our management team and Board of Directors as a sign of confidence in our mission."

Dr. Lederman continued, "We remain on track to commence our first pivotal trial of TNX-102 SL in FM next quarter. FM is considered an intractable problem that affects five million Americans. We also plan to commence a proof of concept study of TNX-102 SL in PTSD in the fourth quarter of this year. PTSD is one of the most important problems facing our society, particularly among soldiers and veterans. TNX-102 SL is the result of disruptive innovation by our team, for which we own worldwide rights with no future obligations to third-parties." 

As a result of the Reverse Split, the number of outstanding common shares will be reduced from 43,949,267 to 2,197,464, subject to adjustment for fractional shares. No fractional shares are to be issued, with fractional shares of common stock to be rounded up to the nearest whole share. It is not necessary for shareholders 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 Split, although shareholders may do so if they wish. Shareholders should direct any questions concerning the Reverse Split to their broker or the Company's transfer agent, vStock Transfer, at 212-828-8436.
