REDWOOD CITY, Calif., April 21, 2011 — Informatica Corporation (NASDAQ: INFA), the world’s number one independent provider of data integration software, today announced financial results for the first quarter ended March 31, 2011.

“The secular technology trends of cloud computing and big data are expanding our addressable market as well as elevating the critical role of data integration within the IT infrastructure,” said Sohaib Abbasi, chairman and CEO, Informatica. “Our first quarter results are yet further evidence that Informatica’s value proposition aligns well with the top priorities of our customers. In these uncertain times of change, data integration matters more than ever.”

Financial Highlights for the First Quarter Ended March 31, 2011

Total revenues for the first quarter of 2011 were a record $168.0 million, an increase of 24 percent from $135.1 million recorded in the first quarter of 2010. License revenues were $71.5 million, an increase of 30 percent from the $55.0 million recorded in the first quarter of 2010.

Income from operations for the first quarter of 2011, calculated in accordance with U.S. generally accepted accounting principles (GAAP), was $31.9 million, up 114 percent from $14.9 million in the first quarter of 2010.

GAAP net income for the first quarter of 2011 was $21.9 million or $0.20 per diluted share, up over 66 percent from $11.8 million or $0.12 per diluted share in the first quarter of 2010. For the three-month periods ended March 31, 2011 and March 31, 2010, respectively, earnings per diluted share is calculated on an “if converted” basis, including the add-back of $0.8 million and $1.0 million of interest and convertible notes issuance cost amortization, net of applicable income taxes.

Non-GAAP income from operations for the first quarter of 2011 was $44.6 million, up 48 percent from $30.2 million in the first quarter of 2010. Non-GAAP net income for the first quarter of 2011 was $30.9 million or $0.28 per diluted share, up over 33 percent from $21.1 million or $0.21 per diluted share in the first quarter of 2010. Non-GAAP income from operations and non-GAAP net income exclude charges and tax benefits related to the amortization of acquired technology and intangible assets, facilities restructurings, acquisitions and other expenses, investment gains and stock compensation. A reconciliation of GAAP results to non-GAAP results is included below.

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 (“Stock Compensation”) 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.
