Results for the first nine months of 2006 reflect the impact of share-based compensation as required by Financial Accounting Standards (FAS) 123R,

whereas 2005 results exclude these expenses. Non-GAAP net income for the first nine months of 2006 was $39.0 million or $0.41 per diluted share, up over 55 percent from $24.7 million or $0.27 per diluted share in the first nine months of 2005.

Non-GAAP Financial Information

     To supplement the company’s condensed consolidated financial statements presented on a GAAP basis, Informatica uses non-GAAP financial measures of net income and net income per share. These measures are adjusted to exclude the charges and expenses discussed above. The company believes the disclosure of such non-GAAP financial measures is appropriate to enhance an overall understanding of its historical financial performance. These adjustments to the company’s GAAP results are made with the intent of providing both management and investors a more complete understanding of the company’s underlying operational results, trends, and marketplace performance. Informatica believes that the inclusion of these non-GAAP financial measures provides consistency and comparability with its historical financial results, as well as comparability to similar companies in the company’s industry, many of which present similar

non-GAAP financial measures to investors. In addition, these non-GAAP financial measures are among the primary indicators management uses as a basis for its planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income or net income per share prepared in accordance with generally accepted accounting principles in the U.S.
