Forward-Looking Statements

This release contains forward-looking statements, and any statements other than statements of historical facts could be deemed to be forward-looking statements. These forward-looking statements include, among other things, statements regarding future events (such as statements regarding ramping up production, customer demand for and value of our anticipated products, and product sales) that involve risks and uncertainties. These statements are based on management’s current expectations and actual results and future events may differ materially due to risks and uncertainties, including those associated with any delays in production and commercialization of products and other risks detailed in the “Risk Factors” section of Amyris’s Form 10-K, as filed on March 14, 2011 pursuant to Rule 424(b) under the Securities Act of 1933.

Non-GAAP Financial Information

Consolidated financial information has been presented in accordance with GAAP as well as on a non-GAAP basis. On a non-GAAP basis, financial measures exclude non-cash items such as stock-based compensation. Management believes that it is useful to supplement its GAAP financial statements with this non-GAAP information because management uses such information internally for its operating, budgeting and financial planning purposes. These non-GAAP financial measures also facilitate management’s internal comparisons to Amyris’s historical performance as well as comparisons to the operating results of other companies. In addition, Amyris believes these non-GAAP financial measures are useful to investors because they allow for greater transparency into the indicators used by management as a basis for its financial and operational decision making. Non-GAAP information is not prepared under a comprehensive set of accounting rules and therefore, should only be read in conjunction with financial information reported under U.S. GAAP when understanding Amyris’s operating performance. A reconciliation between GAAP and non-GAAP financial information is provided in the financial statement tables below.
