Metabolix Announces Fourth Quarter and Full Year 2013 Financial Results

Achieves Milestones Across Business Platforms

Provides Outlook for Priorities in 2014

CAMBRIDGE, Mass. — March 27, 2014 — Metabolix, Inc. (NASDAQ: MBLX), an innovation-driven performance biomaterials company delivering sustainable solutions to the plastics and chemicals industries, today reported financial results for the three months and full year ended December 31, 2013.

Recent Highlights:

·                  Presented data demonstrating use of Metabolix PHA biopolymers as a performance and process enhancing additive in PVC and PLA applications

·                  Launched Mvera B5011, a new film grade resin that allows for production of highly transparent compostable film and bags

·                  Achieved technical milestones for production of PHA in latex form with target applications in biobased, biodegradable barrier coatings for paper and cardboard

·                  Demonstrated use of second generation cellulosic sugars as feedstock for PHA biopolymer and biobased chemical products

·                  Achieved significant increase in yield in microbial strains used to produce bioacrylic from either corn sugar or second generation cellulosic sugars

“We accomplished several milestones across our business platforms during the fourth quarter of 2013 and early 2014,” said Joseph Shaulson, president and CEO of Metabolix. “By intensifying our commercialization efforts in the performance additive space and introducing new products that extend our footprint in latex and film applications, we are creating opportunities to develop solutions matched to customer needs. At the same time, we continue to advance our technology in biopolymers, biobased chemicals, and crop science with the objective of building value in these platforms.

“In 2014, we will be focused on a number of key milestones tied to our business plan,” Shaulson continued. “Financing the execution of that plan is at the top of our agenda. Selection and build-out of an intermediate-scale (2.5 to 5 KTPA) manufacturing site for commercial production of Metabolix biopolymers is also a high priority.  In that regard, we are making excellent progress with site selection and our goal is to have manufacturing up and running in 2015. Of course, this is subject to securing financing for the manufacturing site and for continued operations.

“In anticipation of commercial production, we are also sharpening our emphasis on developing performance additive solutions that deliver the greatest combination of value and performance to our customers. This is driving a shift in our approach to product and application development, as we work closely with customers from initial data demonstration, through product and process validation, larger-scale trials and ultimately to final purchasing decisions. We are confident in our strategy and excited by the opportunity to execute our business plan through the balance of 2014 and 2015. Ultimately, this should position us to move forward with longer-range plans for larger scale manufacturing supported by customer demand for Metabolix PHA biopolymers and create significant value for all of our stakeholders,” said Shaulson.

“Today, Metabolix reported 2013 financial results consistent with our internal expectations. We ended the year with $19.2 million in cash and unrestricted investments, and we anticipate ending the first quarter 2014 with approximately $10.0 million,” said Shaulson. “Based on our current plans and projections, which remain subject to numerous uncertainties, we plan to raise $50 to $60 million over the next 12 to 15 months. The timing, structure and vehicles for obtaining this financing are under consideration and it may be accomplished in stages. Although we can not guarantee the availability of financing, our goal is to use this capital to build an intermediate-scale specialty polymers business based on PHA biopolymer additives that serves as the foundation for our longer-range plans and the future growth of our business.”

FULL YEAR AND FOURTH QUARTER 2013 FINANCIAL OVERVIEW

Metabolix manages its finances with an emphasis on cash flow and deploys its financial resources in a disciplined manner to achieve its key strategic objectives and to maximize value from its technology and product portfolio. The Company has maintained this focus and ended 2013 with $19.2 million in unrestricted cash and investments. The Company’s net cash used in operating activities during 2013 was $26.6 million, which represents a decrease in cash usage of $5.1 million from the $31.7 million used for operating activities during 2012.

For 2013, the Company reported a net loss of $30.5 million, or $0.88 per share, as compared to net income of $3.6 million, or $0.11 per share, for 2012.

Total revenue for the full year 2013 was $5.4 million, compared to $42.3 million recorded in the prior year. The year-over-year decrease was primarily due to $38.9 million in deferred revenue that was recognized in 2012 as a result of the termination of the Telles joint venture.  Product revenue increased by $0.9 million to $2.1 million during 2013, as compared to $1.2 million recorded during 2012.  The increase is primarily attributable to higher biopolymer sales in 2013.

Cost of product revenue for the full year 2013 was $3.0 million, compared to $1.4 million in the prior year.  These costs include the cost of inventory associated with product revenue recognized during the respective periods, together with warehousing and freight costs incurred during the periods.  Cost of product revenue also includes inventory impairment charges of $0.8 million and $0.1 million during 2013 and 2012, respectively.

Research and development expenses were $19.1 million in 2013, compared to $23.2 million for 2012. The decrease of $4.1 million is primarily due to $2.3 million in charges incurred with a third party during 2012 for a manufacturing demonstration agreement that the Company terminated and $1.8 million associated with cost reductions.

Selling, general and administrative expenses were $13.7 million and $14.1 million for the years ended December 31, 2013 and 2012, respectively. The $0.4 million decrease was primarily due to a reduction in fees for patent related activities and a reduction in litigation costs.  During 2013, reductions in employee compensation and benefit expenses as a result of the Company’s 2012 restructuring were offset by $0.8 million of one-time costs associated with the replacement of the Company’s chief executive officer.

The Company reported a net loss of $8.6 million, or $0.25 per share, for the fourth quarter of 2013, compared to a net loss of $9.5 million, or $0.28 per share, for the fourth quarter of 2012. During the fourth quarter of 2013, the Company’s net cash used for operating activities was $6.4 million, which decreased from net cash used of $7.3 million for the comparable quarter in 2012.

Total revenue in the fourth quarter of 2013 was $0.9 million, compared to $1.4 million for the comparable quarter in 2012. The fourth quarter revenue consisted primarily of revenue from product sales and government grants. Biopolymer product orders of $0.5 million were shipped and billed during the Company’s fourth quarter of 2013. Revenue recognition was deferred for the majority of these shipments in accordance with the Company’s policy to defer product revenue for the greater of 60 days or until receipt of customer payment.  The Company recognized $0.2 million in product revenue during the fourth quarter of 2013, primarily from product shipments made during its third fiscal quarter.

In the fourth quarter of 2013, research and development expenses were $4.7 million, and selling, general and administrative expenses totaled $4.0 million.

The accompanying condensed consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern.  However, with the exception of 2012, when the Company recognized $38.9 million of deferred revenue from the terminated Telles joint venture, it has recorded losses since its inception, including the fiscal year ended December 31, 2013.  The Company ended 2013 with $19.2 million in cash and unrestricted investments and anticipates it will end the first quarter of 2014 with approximately $10.0 million.  The Company’s present capital resources are not sufficient to fund its planned operations for a twelve month period, and therefore, raise substantial doubt about its ability to continue as a going concern.  The Company will, during 2014, require significant additional funding.  While the Company plans to raise $50 to $60 million over the next 12 to 15 months, if it is unable to raise additional funds, the Company will be forced to delay, scale back or otherwise modify its business and manufacturing plans, sales and marketing efforts, research and development activities and other operations, and/or seek strategic alternatives.
