BioAmber Announces Year End Operational and Financial Results for 2015

Montreal, Canada, March 14, 2016. BioAmber Inc. (NYSE: BIOA), a leader in renewable materials announced operational and financial results for the three months and year ended December 31, 2015.  The highlights included:

“We made excellent progress in Sarnia during the fourth quarter.  Fermentation continued to perform very well and purification improved steadily over the quarter as we spent more time operating the equipment, made minor modifications to the process and our operators gained experience.  We encountered typical problems expected during a start-up, but we were successful in producing quality product at a competitive cost, and initiating customer sales” said Jean-Francois Huc, BioAmber’s Chief Executive Officer.  “Mitsui & Co.’s recent investment in Sarnia strengthens our balance sheet and is a strong endorsement from a leading global player that is very active in the renewables sector and has intimate knowledge of the Sarnia plant,” he added.

Full Year 2015 Financial Results

Revenues for the year ended December 31, 2015 increased to $2.2 million from $1.5 million last year.  This included sales of $1.1 million in the fourth quarter of 2015.  Average selling prices declined from 2014 as customers obtained lower pricing for production coming out of the Sarnia facility.

Gross loss for the year ended December 31, 2015 decreased to $441,000 from $4.5 million last year. This was due to a reduction in the cost of goods sold, driven by lower costs for product made in Sarnia as compared to the cost of product made in the French demo plant, the inventory write down taken in 2014 and the toll-manufacturing fixed costs, which did not occur in 2015.  

Research and development expenses for the year ended December 31, 2015 increased to $20.3 million from $15.2 million last year.  This was driven primarily by an increase in expenses related to the commissioning and start-up of the Sarnia plant, partially offset by a reduction in BDO related expenses now being performed by Davy and capitalized, and a reduction in stock-based compensation expense due to cancellations from 2014.

Sales and marketing expenses for the year ended December 31, 2015 decreased to $4.0 million from $4.5 million last year.

General and administrative expenses for the year ended December 31, 2015 decreased to $10.6 million from $10.7 million last year. This was primarily due to Canadian dollar depreciation against the U.S. Dollar from 2014 to 2015 and stock-options cancellation from 2014, partially offset by financing costs.

For the year ended December 31, 2015, the company recorded a non-cash impairment charge of $1.1 million following the termination of our license agreement with DuPont.

Depreciation of property and equipment and amortization of intangible assets expense increased to $1.1 million for the year ended December 31, 2015 from $260,000 for the same period last year. This increase was due to the depreciation of the Sarnia facility assets following the beginning of production in the fourth quarter of 2015.

For the year ended December 31, 2015, the Company incurred a net financial charge of $1.6 million as compared to a charge of $11.8 million last year.  The net financial charge for the year was the result of interest expense on long-term loans, including accretion for the end of term charge on the Company’s long-term loan from Tennenbaum Capital Partners, in the amount of $3.6 million. The net financial charge was partially offset by a $2.3 million non-cash gain related to changes in the fair market value of the warrants issued in connection with the Company’s initial public offering (IPO Warrants) and warrants issued in 2009 and 2011 (Legacy Warrants).

Foreign exchange loss for the year ended December 31, 2015 increased to $1.0 million from $151,000 last year. This was driven by the weaker Canadian dollar versus the US dollar, which negatively impacted the value of cash balances held in Canadian dollars.

The Company recorded a net loss attributable to BioAmber Inc. shareholders of $37.2 million, or a loss of $1.52 per share for the year ended December 31, 2015, compared to a net loss of $46.5 million, or a loss of $2.32 per share last year.

The Adjusted Net Loss Attributable to BioAmber Inc. Shareholders for the year ended December 31, 2015 was $38.0 million, or a loss of $1.55 per share, compared to an Adjusted Net Loss Attributable to BioAmber Inc. Shareholders of $34.7 million, or a loss of $1.74 per share in 2014.  Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is a non-GAAP financial metric that excludes, for the year ended December 31, 2015, the impact of the change in fair value of the IPO and Legacy Warrants, the intangible asset impairment and the non-cash inventory reserve.  The Adjusted Net Loss Attributable to BioAmber Inc. Shareholders for the year ended December 31, 2014 excludes the impact of the change in the fair value of the IPO and Legacy Warrants the non-cash inventory reserve expense, the non-cash gain resulting from debt extinguishment, and the non-cash expense resulting from the cancellation of certain employee stock options.

ANNEX A: Non-GAAP Financial Information

Adjusted Net Loss Attributable to BioAmber Inc. Shareholders

BioAmber presents Adjusted Net Loss Attributable to BioAmber Inc. Shareholders as a supplemental measure of BioAmber’s performance.  Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is a non-GAAP financial metric that excludes, for the quarter ended December 31, 2015, the impact of the change in fair value of the warrants issued in connection with the Company’s IPO and the Legacy Warrants issued in 2009 and 2011 that were reclassified from equity to a liability a non-cash inventory reserve expense and, for the year ended December 31, 2015, the foregoing items plus a charge for intangible and long-lived asset impairment.  This non-GAAP financial metric also excludes, for the quarter ended December 31, 2014, the impact of the change in fair value of the warrants issued in connection with the Company’s IPO and the Legacy Warrants, the non-cash inventory reserve expense, the non-cash gain resulting from debt extinguishment and, for the year ended December 31, 2014, the foregoing items plus an additional charge for cancellation of stock options.   The above items are excluded from BioAmber’s Adjusted Net Loss Attributable to BioAmber Inc. Shareholders because these items are non-cash in nature, or because the amount and timing of these items are either unpredictable or not driven by current operating results and renders comparisons with prior periods and competitors less meaningful.  BioAmber believes Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is a useful measure for analysts and investors to evaluate BioAmber’s future ongoing performance as this measure allows for a more meaningful comparison of BioAmber’s projected cash earnings and performance with its historical results from prior periods and to the results of its competitors.  Adjusted Net Loss Attributable to BioAmber Inc. Shareholders corresponds more closely to the cash operating income generated from BioAmber’s business and allows investors to gain an understanding of the factors and trends affecting the ongoing cash earnings capabilities of BioAmber’s business.

Adjusted Net Loss Attributable to BioAmber Inc. Shareholders has certain limitations in that it does not take into account the impact of certain expenses to BioAmber’s consolidated statements of operations.  In evaluating Adjusted Net Loss Attributable to BioAmber Inc. Shareholders, you should be aware that in the future BioAmber may incur expenses similar to the adjustments in this presentation. BioAmber’s presentation of Adjusted Net Loss Attributable to BioAmber Inc. Shareholders should not be construed as an inference that BioAmber’s future results will be unaffected by unusual or non-recurring items. Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is not a measurement of BioAmber’s financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP.
