Solazyme Reports Second Quarter 2013 Results

Solazyme Bunge Renewable Oils Production Facility on Track for Q4; Commissioning Schedule Accelerated at Clinton Facility;

Announces High Erucic Tailored Oil within Mitsui JDA and Commercial Supply Terms Finalized with Sasol

South San Francisco, CA – August 7, 2013 – Solazyme, Inc. (NASDAQ: SZYM), a renewable oil and bioproducts company, announced results today for the second quarter ended June 30, 2013.

“We are making great progress as we approach commencement of manufacturing at our commercial production facilities later this year,” said Jonathan Wolfson, CEO of Solazyme. “Capacity build-out at our Brazilian JV facility remains on target, and we are actually accelerating plans at the Clinton, Iowa facility, which should allow us to begin producing product for market and application development during the second half of this year. Peoria is also being retrofitted to produce algal flour and protein products with availability of commercial development quantities also expected in the second half of this year. Tailored oil technology breakthroughs are continuing to open additional attractive end market opportunities, as evidenced by the announcement of the new high erucic tailored oil under development with Mitsui and the related commercial supply terms with Sasol.”

Financial Results

Total revenue for the second quarter ended June 30, 2013 was $11.2 million compared with $13.5 million in the second quarter of 2012. Revenues in the second quarter of 2013 included $4.9 million of product sales compared to $4.1 million in the same period of 2012, an increase of 21%. In the second quarter of 2013, development revenues with commercial partners came in at $6.2 million versus $4.7 million, an increase of 33% over the same period in the prior year. The increases in product and development revenues with commercial partners were offset by lower government funded revenues, in line with our expectations.

Second quarter GAAP net loss attributable to Solazyme, Inc. common stockholders was $25.8 million, which compares with net loss of $19.2 million in the prior year period. On a non-GAAP basis, the net loss was $17.4 million for the second quarter of 2013, compared with net loss of $16.3 million in the prior year quarter. A reconciliation of GAAP to non-GAAP results is included below.

“Our second quarter results keep us on track to achieve our full year objectives,” said Tyler Painter, CFO of Solazyme. “Our operating and capital expenditures remain within our expectations. As we near the commencement of production at Moema and Clinton, our commercialization path is supported by a strong capital structure and a supportive group of partners.”

Non-GAAP Financial Measures

This press release includes the following financial measure defined as a “non-GAAP financial measure” by the Securities and Exchange Commission: non-GAAP net loss. This measure may be different from non-GAAP financial measures used by other companies. The presentation of this financial information, which is not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with generally accepted accounting principles. For a reconciliation of this non-GAAP financial measure to the nearest comparable GAAP measure, see “Reconciliation of GAAP to Non-GAAP Basic Net Loss Per Share” included in the tables to this press release.

This non-GAAP measure is provided to enhance investors’ overall understanding of Solazyme’s current financial performance and Solazyme’s prospects for the future. Specifically, Solazyme believes the non-GAAP measure provides useful information to both management and investors by excluding certain expenses that may not be indicative of its core operating results and business outlook.

For its internal budgeting process, Solazyme’s management uses financial measures that do not include stock-based compensation expense or special expenses such as non-cash gains or losses due to warrant revaluations. In addition to the corresponding GAAP measures, Solazyme’s management also uses the foregoing non-GAAP measure in reviewing the financial results of Solazyme. Solazyme excludes stock-based compensation expenses and special non-cash charges from its non-GAAP measures primarily because they are non-cash expenses that management does not believe are reflective of ongoing operating results.
