  • Underwriter’s Option to Purchase Additional Securities Exercised in Full

/EIN News/ -- NEWTOWN, Pa., May 01, 2018 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ:ONTX) (“Onconova” or “we”), a Phase 3 stage biopharmaceutical company focused on discovering and developing small molecule drug candidates to treat cancer, with a primary focus on Myelodysplastic Syndromes, today announced the closing of its previously announced underwritten public offering (the “Offering”) of 67,647,058 shares of its common stock (“Common Stock”) (or Common Stock equivalent) and warrants to purchase an aggregate of 1,691,176.450 shares of Onconova’s Series B convertible preferred stock (“Preferred Stock Warrants”), including 8,823,529 shares of Common Stock and Preferred Stock Warrants to purchase 220,588.225 shares of Series B convertible preferred stock issued pursuant to the underwriter’s full exercise of its option to purchase additional securities, at the public offering price of $0.425 per share and accompanying Preferred Stock Warrant.

H.C. Wainwright & Co. acted as the sole book-running manager for the Offering.

The gross proceeds of the Offering were approximately $28.75 million and, after deducting underwriting discounts and commissions and offering expenses, the net proceeds of the Offering were approximately $25.6 million. In addition, in the event the Preferred Stock Warrants are exercised in full, Onconova expects to receive approximately $28.75 million in additional proceeds.  However, there is no assurance that all or a portion of the Preferred Stock Warrants will be exercised prior to their expiration. 

The Preferred Stock Warrants are exercisable immediately at an exercise price of $0.425 per 0.025 share of Series B Preferred Stock (convertible into one share of Common Stock) and will expire on the 18-month anniversary of the date on which Onconova publicly announces through the filing of a Current Report on Form 8-K that an amendment to its certificate of incorporation to increase its authorized shares of Common Stock has been filed with the Secretary of State of the State of Delaware.  The shares of Common Stock (or Common Stock equivalents) and the accompanying Preferred Stock Warrants were purchased together in this Offering but were issued separately. 

Onconova intends to use the net proceeds from this Offering to fund the development of its clinical and preclinical programs, for other research and development activities and for general corporate purposes, which may include capital expenditures and funding working capital needs.
