Total revenues for the third quarter of 2010 were a record $161.3 million, an increase of 31 percent from $123.4 million recorded in the third quarter of 2009. License revenues were $69.8 million, an increase of 40 percent from $50.0 million recorded in the third quarter of 2009.

Non-GAAP Financial Information

To supplement Informatica’s condensed consolidated financial statements prepared and presented on a GAAP basis, Informatica uses non-GAAP financial measures of income from operations, net income and net income per share. These measures are adjusted from income from operations, net income or net income per share prepared in accordance with GAAP to exclude the charges and expenses discussed above. The presentation of these non-GAAP financial measures are not meant to be considered in isolation or as a substitute for, or superior to, income from operations, net income or net income per share prepared in accordance with GAAP.

Informatica believes the disclosure of such non-GAAP financial measures is appropriate to enhance an overall understanding of its financial performance, its financial and operational decision making, and as a means to evaluate period to period comparisons. These adjustments to the Company’s GAAP results are made with the intent of providing both management and investors a more complete understanding of Informatica’s performance, by excluding certain expenses and expenditures such as non-cash charges and discrete charges that are infrequent in nature, such as charges related to acquisitions, that may not be indicative of its underlying operating results. In addition, Informatica 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. Informatica believes that the disclosure of these non-GAAP financial measures provides consistency and comparability of its recent financial results with its historical financial results, as well as to the operating results of similar companies in Informatica’s industry, many of which present similar non-GAAP financial measures to investors. As an example, Informatica believes that it enhances comparability with similar companies’ operating results by excluding stock compensation in its non-GAAP financial measures because of the different types of stock-based awards that companies may grant and because ASC 718 allows companies to use different valuation methodologies and subjective assumptions. In addition, Informatica believes that both management and investors benefit from referring to these non-GAAP financial measures when planning, analyzing and forecasting future periods.

There are a number of limitations related to these non-GAAP financial measures: (1) the non-GAAP measures exclude some costs that are recurring, particularly stock compensation, and we believe that stock compensation will continue to be a significant recurring expense for the foreseeable future; because stock compensation is an important part of our employees’ compensation, such payments can impact their performance; and (2) the items we exclude in our non-GAAP measures may differ from the components our peer companies exclude when they report their non-GAAP measures. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP measures and evaluating non-GAAP measures together with the corresponding measures calculated in accordance with GAAP.

Forward Looking Statements

This press release contains forward-looking statements relating to growth opportunities, customer demand, the benefits of our product portfolio and operational results. Such statements involve risks and uncertainties, and actual results may differ materially from the results described in this press release. The potential risks and uncertainties that could cause actual results to differ include, among others, risks related to (1) competition with larger companies that have longer operating histories and greater financial, technical, marketing, and other resources; and (2) uncertainty in the state of IT spending and the continued growth in the market for data integration solutions in general. Additional risks and uncertainties are included under the caption “Risk Factors” in Informatica’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2010, which has been filed with the SEC and is available on our investor relations website at http://www.informatica.com.
