INFORMATICA REPORTS RECORD SECOND QUARTER RESULTS

Achieves Revenue Growth of 21 Percent and Operating Margin Increase of 300 Basis Points

REDWOOD CITY, Calif., July 17, 2008 — Informatica Corporation (NASDAQ: INFA), the leading independent provider of enterprise data integration software and services, today announced financial results for the second quarter ended June 30, 2008.

     Revenues for the second quarter of 2008 were $113.8 million, up 21 percent from the $94.3 million recorded in the second quarter of 2007. License revenues for the second quarter were $48.5 million, up 16 percent from the $41.8 million recorded in the second quarter of 2007. Net income for the second quarter, calculated in accordance with U.S. generally accepted accounting principles (GAAP), was $11.5 million or $0.12 per diluted share, up more than 9 percent from net income of $10.5 million or $0.11 per diluted share in the second quarter of 2007. For the three-month periods ended June 30, 2007 and June 30, 2008, earnings per diluted share is calculated on an “if converted” basis, including the add-back of $1.1 million of interest and convertible notes issuance cost amortization, net of income taxes.

     Non-GAAP net income for the second quarter of 2008 was $16.7 million or $0.17 per diluted share, up more than 6 percent from $15.6 million or $0.16 per diluted share in the second quarter of 2007. Non-GAAP net income excludes charges related to purchased in-process research and development, share-based payments, facilities restructurings and the amortization of acquired technology and intangible assets. A reconciliation of GAAP operating results and non-GAAP results is included below.

     For the six-month period ended June 30, 2008, revenues were $217.5 million, an increase of 20 percent from the $181.4 million recorded for the first six months of 2007. License revenues for the first six months of 2008 were $92.7 million, up 17 percent from $79.4 million in the first six months of 2007. GAAP net income for the first six months of 2008 was $22.7 million or $0.24 per diluted share, up over 14 percent versus $19.6 million or $0.21 per diluted share in the

first six months of 2007. Non-GAAP net income for the first six months of 2008 was $32.4 million or $0.33 per diluted share, up over 6 percent versus $30.0 million or $0.31 per diluted share in the first six months of 2007. For the six-month periods ended June 30, 2007 and June 30, 2008, earnings per diluted share is calculated on an “if converted” basis, including the add-back of $2.2 million of interest and convertible notes issuance cost amortization, net of income taxes.

     “We are pleased with our record second quarter results” said Sohaib Abbasi, chairman and CEO of Informatica. “These results further highlight that our value proposition for IT organizations to “do more with less” has promoted even broader customer adoption of our products and services in the current macroeconomic environment.”

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 GAAP in the U.S.

Such statements involve risks and uncertainties, and actual results may differ materially from the results described in this press release.
