INFORMATICA REPORTS 31 PERCENT LICENSE-REVENUE GROWTH
Achieves record first-quarter earnings and revenues

REDWOOD CITY, Calif., April 20, 2006 — Informatica Corporation (NASDAQ: INFA), a leading provider of data integration software, today announced financial results for the first quarter ended March 31, 2006.

     Revenues for the first quarter of 2006 were $73.1 million, up 25 percent from the $58.4 million recorded in the first quarter of 2005. Net income for the first quarter, calculated in accordance with U.S. generally accepted accounting principles (GAAP), was $5.3 million or $0.06 per diluted share, up 20 percent from net income of $4.3 million or $0.05 per diluted share in the first quarter of 2005. Results for the first quarter of 2006 reflect the impact of equity-based compensation as required by Financial Accounting Standards (FAS) 123R, whereas 2005 results exclude these expenses. Non-GAAP net income for the first quarter of 2006 was $11.3 million or $0.12 per diluted share, up over 71 percent from $6.4 million or $0.07 per diluted share in the first quarter of 2005.

     Non-GAAP net income excludes charges related to purchased in-process research and development, equity-based compensation, facilities restructurings and the amortization of acquired technology and intangible assets. A reconciliation of GAAP operating results and non-GAAP results is included below.

     “Our sustained record results highlight that our growth strategy is well aligned with our customers’ business imperatives,” said Sohaib Abbasi, chairman and CEO of Informatica. “Thirty one percent license-revenue growth is yet another step towards establishing Informatica as the dominant leader in the enterprise data integration market.”

Significant milestones achieved since January include:

• Signed repeat business with 154 customers.Customers continue to derive considerable value from their investments in Informatica solutions. Repeat customers included American Express Travel Related Services, American Greetings Corporation, China Administration of Taxation, Circuit City, Deutsche Bank, Habitat For Humanity International, Loyalty Group, Natexis Banques Populaires, ShinKong Life Insurance, Stock Exchange of Thailand, and TIAA-CREF.

• Grew customer base to 2,550.Informatica completed transactions with 46 new customers. Another 93 customers were added as a result of the acquisition of Similarity Systems. New customers included Affymetrix, Australia Department of Education & Training, BNSF Railway Company, China Development Bank, General Re Services Corporation, SanDisk Corporation, and the Toronto District School Board.

• Acquired leading data quality vendor. Further extending its technology leadership, Informatica acquired Dublin, Ireland-based Similarity Systems, the leading provider of business-focused data quality solutions. Similarity Systems’ patented technology for data quality includes capabilities for data profiling, standardization, cleansing, matching and monitoring. Informatica will offer these capabilities on a standalone basis and integrate them into the PowerCenter data integration product suite.

• Raised $230 million in convertible senior notes offering. Informatica intends to use the net proceeds for working capital and general corporate purposes, which may include the acquisition of businesses, products, product rights, technologies, or strategic investments. Informatica also used $50 million of the net proceeds from the offering to fund the purchase of shares of its common stock concurrently with the offering of the notes.

• Appointed chief marketing officer.Bringing a broad background in marketing enterprise software, Brian C. Gentile joined Informatica as executive vice president and chief marketing officer (CMO) responsible for worldwide marketing. Most recently the CMO for Aspect Communications, Gentile has more than 21 years of success in developing and leading the product strategy and go-to-market initiatives at several public enterprise software companies.

• Expanded sales presence in Asia Pacific region. Informatica continued expanding its direct presence in the Asia Pacific region, establishing representative offices in Sydney, Australia and Singapore in the first quarter.

• Enabled award-winning customer implementations.Informatica’s PowerCenter data integration platform was a critical component of Virginia’s Fairfax County Public Schools winning a coveted 2006 CIO Magazine Enterprise Value Award for its patented Education Decision Support Library (EDSL), a comprehensive repository of educational information. Informatica technology also enabled the Hong Kong Hospital Authority to win the 2006 Asia Pacific Information and Communication Technology Award (APICTA) for its comprehensive clinical-data repository.

Stock Repurchase Program

     Informatica also today announced that its board of directors has authorized a $30 million stock repurchase program. The company expects to repurchase shares to partially offset the otherwise dilutive impact of stock option exercise activity.

     Purchases may be made, from time to time, in the open market and will be funded from available working capital. The number of shares to be purchased and the timing of purchases will be based on several factors, including the price of Informatica’s stock, general business and market conditions, and other investment opportunities.

Conference Call and Webcast

     Informatica will be discussing its first quarter 2006 results on a conference call today beginning at 2:00 p.m. PDT. A live Webcast of the conference call will be available at http://www.informatica.com/investor. A replay of the call will also be available by dialing 617-801-6888, reservation number 51463585.

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 United States.

Safe Harbor

Informatica’s intentions with regard to the stock repurchase program may be affected by a number of factors, which include the market price of the company’s stock, general business and market conditions, and management’s determination of alternative needs and uses of the company’s cash resources as well as those risks and uncertainties included under the caption “Risk Factors” in Informatica’s report on Form 10-K for the year ended December 31, 2005, which is on file with the SEC and is available on the company’s investor relations website at www.informatica.com.
