BioAmber Reports Second Quarter 2014 Financial Results

Minneapolis, MN, August 7, 2014. BioAmber Inc. (NYSE: BIOA), an industrial biotechnology company producing sustainable chemicals, today announced its financial results for the quarter ended June 30, 2014.  Highlights for the quarter included:

“Sarnia is our focus and we continue to be on budget and scheduled to complete construction in early 2015,” said Jean-Francois Huc, BioAmber’s Chief Executive Officer.  “We were successful in securing an additional CDN$27 million in non-dilutive funding for Sarnia, which combined with our recent share offering, strengthens our balance sheet and provides us with a cushion to become cash flow positive.  Our take-or-pay agreements with PTTMCC Biochem and Vinmar guarantee that 50% of Sarnia capacity will be sold during the first three years of operation, and they lay out a clear path for future growth by securing the sale of most of the output from two additional plants” he added.

Q2 2014 Financial Results

Revenue for the quarter ended June 30, 2014 decreased to $415,000 from $1,028,000 for the same period in 2013. The decrease was principally due to sales to two customers in Q2 2013 that will not recur until the Sarnia plant comes on line.  Excluding these one-time sales, the volume sold in the second quarter of 2014 was 40% higher than the same period in 2013.  Sales increased by 18% in the second quarter of 2014 relative to sales of $351,000 in the previous quarter.  The Company continued to manage sales in an effort to increase inventory levels in advance of the Sarnia start up, with inventory volume increasing by 18% on June 30, 2014 relative to March 31, 2014.  

Gross loss in the quarter ended June 30, 2014 was $1,836,000 compared to a gross loss of $383,000 for the same period in 2013.   The increased loss was primarily due to the recording of a non-cash charge for an inventory reserve in the amount of $1,635,000.  The reserve was taken to bring the recorded value of inventory in line with its net realizable value.  The reduction in net realizable value was driven by the reduction seen in the average selling price.  The Company’s average selling price remains approximately twice the average selling price projected for Sarnia, but is declining as certain customers request Sarnia pricing in advance of the plant starting production.

Research and development expenses for the quarter ended June 30, 2014 were $4.3 million, a slight increase of $38,000 from the same period in 2013.

Sales and marketing expenses in the quarter ended June 30, 2014 were $1.7 million, up slightly from $1.6 million in the same period in 2013.  The increase was due to an increase in incentive remuneration and stock-based compensation expense.

General and administrative expenses for the quarter ended June 30, 2014 increased to $2.9 million from $2.3 million for the same period in 2013. The increase was primarily due to additional costs related to compliance and public company operations.

The Company also incurred a $1,853,000 non-cash stock based compensation charge due to the cancellation of 285,250 stock options following their voluntary forfeiture by certain employees and Company advisors.  

Foreign currency gains in the quarter ended June 30, 2014 were $379,000 as compared to a gain of $28,000 for the same period in 2013. The increase was driven by a strengthening of the Canadian Dollar versus the U.S. Dollar in the second quarter of 2014, which positively impacted the value of Canadian Dollar cash balances carried to meet Sarnia vendor obligations.

During the quarter ended June 30, 2014, the Company incurred financial charges of $3.9 million, as compared to a gain of $10.6 million in the same period in 2013.   The financial charges in the quarter were the result of $870,000 of interest expense and an end of term charge accretion on the loan from Hercules Technology Growth Capital, and a $3.0 million non-cash charge related to changes in the fair market value of the warrants issued in connection with the IPO.  In the second quarter of 2013, the Company had recorded a non-cash gain of $11.7 million related to changes in the fair market value of these warrants. The warrants will be revalued in each reporting period resulting in a non-cash amount being recorded in the statement of operations for as long as the warrants remain outstanding.  

The Company recorded a net loss attributable to shareholders of $14.1 million, or a loss of $0.75 per share, for the quarter ended June 30, 2014, as compared to a net loss of $7.2 million, or a loss of $0.47 per share, for the same period in 2013.

The Adjusted Net Loss Attributable to BioAmber Inc. Shareholders for the quarter ended June 30, 2014 was $7.5 million, or a loss of $0.40 per share, compared to an Adjusted Net Loss Attributable to BioAmber Inc. Shareholders of $9.7 million, or a loss of $0.65 per share, for the same period in 2013. Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is a non-GAAP financial metric that excludes, for the quarter ended June 30, 2014, the impact of the change in fair value of the warrants issued in connection with the IPO, the non-cash expense resulting from the cancellation of certain employee stock options and the non-cash reserve taken on the recorded value of inventory.  For the quarter ended June 30, 2013 it excludes the impact of the change in fair value of the warrants issued in connection with the IPO, the non-cash stock option expenses related to the vesting of certain options as a result of the IPO and a non-cash charge related to the impairment of in-process research and development and construction in progress.    Please refer to Annex A: “Non-GAAP Financial Information—Adjusted Net Loss Attributable to BioAmber Inc. Shareholders” for more information regarding this non-GAAP financial metric.

ANNEX A: Non-GAAP Financial Information

Adjusted Net Loss Attributable to BioAmber Inc. Shareholders

Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is a non-GAAP measure that represents net loss attributable to BioAmber Inc. shareholders adjusted to exclude certain non-cash items that impact net income. The Adjusted Net Loss Attributable to BioAmber Inc. Shareholders for the three months ended June 30, 2014 excludes the impact of the change in fair value of the warrants issued in connection with the IPO, the non-cash inventory reserve expense and the non-cash expense resulting from the cancellation of certain employee stock options. The Adjusted Net Loss Attributable to BioAmber Inc. Shareholders for the three months ended June 30, 2013 excludes (i) costs associated with BioAmber’s transition from an E. coli organism as its core technology to a Cargill yeast for the construction of its initial planned manufacturing facility in Sarnia, Ontario, including impairment of in-process research and development and impairment of a long-lived asset (ii) the accelerated vesting of certain employee stock options upon the IPO and (iii) the impact of the change in fair value of the warrants issued in connection with the IPO.  

BioAmber presents Adjusted Net Loss Attributable to BioAmber Inc. Shareholders as a supplemental measure of BioAmber’s performance. 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.
