Use of Non-GAAP and Adjusted EBITDA Financial Measures: These materials include references to non-GAAP revenue, non-GAAP net income/loss, Adjusted consolidated non-GAAP net income/loss, and Adjusted EBITDA. GigOptix believes that these non-GAAP financial measures are important indicators of the ongoing operations of its business and provide better comparability between reporting periods and provide a better baseline for analyzing trends in GigOptix’s operations. GigOptix does not, nor does it suggest that investors should, consider such non-GAAP and Adjusted EBITDA financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. GigOptix believes the disclosure of the effects of these items increases the reader’s understanding of the underlying performance of the business and that such non-GAAP and Adjusted EBITDA financial measures provide investors with an additional tool to evaluate our financial results and assess our prospects for future performance.
