INFORMATICA ANNOUNCES CORRECTION TO REPORTED WEIGHTED
AVERAGE DILUTED SHARES OUTSTANDING

REDWOOD CITY, Calif., July 24, 2006 — Informatica Corporation (NASDAQ: INFA) today announced an adjustment to the weighted average diluted shares outstanding included in the July 20, 2006 earnings release to correct a computational error related to the shares potentially convertible from the recently issued convertible notes. The weighted average shares outstanding (in thousands) for the second quarter of 2006 should have been 93,062 (GAAP) and 93,841 (Non-GAAP) and, for the six month period ending June 30, 2006, should have been 93,832 (GAAP) and 94,686 (Non-GAAP).

This adjustment has no impact on the second quarter GAAP net income, share-based payments, Non-GAAP earnings results, the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows. This correction does not impact Informatica’s business fundamentals or its outlook for future business. Informatica hereby reiterates guidance given on the July 20, 2006 earnings call.

The impact is limited to: (1) adjusting the GAAP net income per diluted share for the second quarter of 2006 from $0.09 to $0.08 and for the six months ending June 30, 2006 from $0.15 to $0.14; and (2) adjusting share-based payments per diluted share for the second quarter of 2006 from $0.03 to $0.04 and for the six months ending June 30, 2006 from $0.06 to $0.07 (as included in the reconciliation of GAAP to Non-GAAP net income per diluted share).

The corrected Condensed Consolidated Statements of Operations are attached to this press release, the corrected Non-GAAP Results are included in this press release and both are available atwww.informatica.com/investor. For convenience, also attached to this press release are the unaffected Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows.

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.
