BioAmber Announces Third Quarter 2017 Financial Results

Montreal, Canada, November 7th, 2017. BioAmber Inc. (NYSE: BIOA, TSX: BIOA) – a leader in renewable materials today announced operational and financial results for the three months ended September 30, 2017.

Highlights:

“I am excited to join BioAmber at this stage of development.  Our technology is proven, we have identified numerous opportunities to drive down our variable costs, and our customer base and application pattern continues to expand,” stated Richard Eno, BioAmber’s Chief Executive Officer. “I look forward to leading the company as we grow our sales from Sarnia creating a foundation for long term profitable growth.”

Q3 2017 Financial Results

Revenues for the quarter ended September 30, 2017 were $3.3 million, a decrease of 10% over the same quarter last year, mainly driven by a decrease in succinic acid volume, slightly offset by an increase in average selling price.

Cost of goods sold increased from $5 million to $6 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016, driven primarily by an increase in production volume and an increase in royalties.

General and administrative expenses increased by $0.6 million to $2.3 million for the three months ended September 30, 2017, as compared to $1.8 million for the three months ended September 30, 2016. This is mainly due to recruiting fees associated with the hiring of a new CEO and an increase in legal fees. Excluding these and other non-recurring charges, general and administrative expenses were flat compared to last year.

Research and development expenses decreased by $0.6 million to $1.2 million for the three months ended September 30, 2017, as compared to $1.8 million for the three months ended September 30, 2016, primarily attributable to a reduction in the R&D efforts required to support the Sarnia facility.

Financial charges (income), net decreased to an income of $0.9 million for the three months ended September 30, 2017 as compared to a charge of $3.2 million for the three months ended September 30, 2016. This variation of $4.1 million is mainly due to the non-cash mark-to-market adjustment change of $3.5 million on all outstanding warrants. It is also attributable to a decrease in interest and end of term charges on long-term debt due to the full repayment of the Bridging Loan in January 2017. This decrease is partially offset by the issuance costs associated with the January 2017 and the August 2017 Warrants classified as liabilities.  

The Company recorded a net loss attributable to BioAmber Inc. shareholders of $7.0 million, or a loss of $0.16 per share, for the quarter ended September 30, 2017, compared to a net loss of $6.2 million, or a loss of $0.21 per share, for the same period last year.

The Adjusted Net Loss Attributable to BioAmber Inc. Shareholders for the quarter ended September 30, 2017 was $9.4 million, or a loss of $0.21 per share, compared to an Adjusted Net Loss Attributable to BioAmber Inc. Shareholders of $7.4 million, or a loss of $0.26 per share, for the three months ended September 30, 2016.  Adjusted Net Loss Attributable to BioAmber Inc. Shareholders is a non-GAAP financial metric that excludes the impact of the change in fair value of the IPO, Legacy, January 207 and August 2017 Warrants and grant revenue.

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.

The above items are excluded from BioAmber's Adjusted Net Loss Attributable to BioAmber Inc.
