BioAmber Inc. announces $7 million underwritten offering of common stock and concurrent $8.9 million registered direct offering of warrants

MONTREAL, Dec. 22, 2016

Additionally, BioAmber announced today that it has conducted a registered direct offering to "permitted investors" in Canada of warrants to purchase an aggregate of 2,224,199 shares of common stock for gross proceeds of approximately $8.9 million.  Each warrant entitles the holder thereof to receive one share of our common stock on the exercise or deemed exercise of the warrant. The warrants are exercisable by the holders thereof at any time for no additional consideration and all unexercised warrants shall be deemed to be automatically exercised following the satisfaction of certain conditions specified in the warrants.  Until such warrants are exercised or automatically exercised following the satisfaction of such conditions, the subscription proceeds from this registered offering of warrants will be placed in escrow.

Rodman & Renshaw, a unit of H.C. Wainwright & Co., is acting as the sole bookrunning manager for both offerings.  AltaCorp Capital Inc. is acting as financial advisor to BioAmber. 

BioAmber intends to use the net proceeds of the underwritten offering and the registered offering of warrants for working capital and other general corporate purposes.  The underwritten offering is expected to close on or about December 29, 2016, subject to customary closing conditions and the closing of the registered direct offering.

The shares of common stock, the warrants and the shares of common stock issuable upon exercise of the warrants described above are being sold by BioAmber pursuant to a shelf registration statement on Form S-3 (No. 333-196470) including a base prospectus, which was declared effective by the Securities and Exchange Commission (the "SEC") on July 9, 2014, and a related registration statement on Form S-3 filed pursuant to Rule 462(b) under the Securities Act of 1933, as amended (Registration No. 333-162379), which became effective upon filing with the SEC on December 23, 2016. Prospectus supplements relating to the offerings of the securities will be filed by the Company with the SEC.
