INFORMATICA REPORTS FIRST QUARTER REVENUES OF $54.2 MILLION

Achieves 81 percent increase in profitability

REDWOOD CITY, Calif., April 20, 2004 - Informatica Corporation (NASDAQ:
INFA), a leading provider of data integration and business intelligence software, today announced financial results for the first quarter ended March 31, 2004.

Revenues for the first quarter of 2004 were $54.2 million, up from the $48.4 million recorded in the first quarter of 2003.  Net income for the first quarter, calculated in accordance with U.S. generally accepted accounting principles (GAAP), was $1.9 million or $0.02 per diluted share, compared with net income of $1.0 million or $0.01 per diluted share in the first quarter of 2003.  Pro forma net income for the first quarter of 2004 was $3.2 million or $0.04 per diluted share, up from $1.4 million or $0.02 per diluted share in the first quarter of 2003.  Pro forma operating results discussed in this press release exclude charges related to the amortization of acquired technology, intangible assets and stock-based compensation.  A reconciliation of pro forma operating results and GAAP results is included in the financial statements attached below.

"Informatica's strengthened sales management, deeper geographic focus and strong product hand translate into customer success and position us for further expansion this year," said Gaurav Dhillon, president and CEO of Informatica. "We believe our persistent focus on infrastructure is paying off and we look to the rest of the year with optimism."

Significant milestones achieved in the first quarter of 2004 include:

• Signed repeat business with 93 customers.  Customers continue to derive considerable value from their investments in Informatica solutions.  Repeat customers included Alltel Communications, Bank of Montreal, Best Buy, CIBC, Cingular Wireless, DaimlerChrysler, Deutsche Bank, Electronic Arts, HP and Sony.
• Signed 55 new customers.  Informatica increased its customer base this quarter to 1,990 companies.  New customers included Cadbury Schweppes Americas Beverages, Lawrence Livermore Labs, Leap Frog Enterprises, New Jersey Manufactures Insurance Group, Ontario Power Generation Inc., Robeco Finance and Worthington Industries.
• Named Oracle veteran to board of directors.  Sohaib Abbasi, a former member of Oracle's executive committee, brings extensive software industry and organization-building experience to Informatica. Abbasi joined Oracle in 1982 and in 1985 envisioned and launched the Oracle Tools business, which he subsequently grew to $3.75 billion in cumulative license revenues. 
• SuperGlue named "visionary" by leading industry analyst firm.  Recently evaluated in leading marketplace research, SuperGlue is the first standards-based enterprise metadata management solution that integrates metadata from disparate systems, and offers thin-client visualization and analysis capabilities for enhanced understanding of an organization's IT environment.  Version 1.5 of SuperGlue is now generally available.
• Further broadened partnership with IBM.  PowerCenter became part of IBM's Risk and Compliance - Basel II Information Management solution.  Informatica continues to work with IBM to add solutions to the existing joint Business Performance Management offering, and also joined IBM's ISV Alliance Advantage program in Europe, the Middle East and Africa to support small to medium-sized enterprises, particularly in the insurance and financial services sector.
• Expanded Informatica Developer Network to 13,500. With a presence in more than 90 countries, Informatica's three-year-old collaborative online community is the largest data integration developer network in the world.  The Informatica Developer Network helps accelerate the creation of effective customer-developed and third-party add-on solutions. 
• Demonstrated 500 percent potential savings with Informatica.  A Total Economic Impact(tm) study by Forrester Consulting found that the Informatica PowerCenter data integration platform offers the potential for ROI of up to $3.5 million and up to 500 percent savings in development costs over hand-coded data integration processes, particularly for global companies with complex data warehouse and data integration needs.
• Announced Informatica World 2004 in Scotland. Informatica's annual user conference will take place May 5-7 in Edinburgh, Scotland.  Key partners such as HP and IBM, as well as key European customers such as British Airways and Deutsche Boerse will present keynotes at the conference.  

To supplement the company's condensed consolidated financial statements presented on a GAAP basis, Informatica uses pro forma measures of net income and net income per share. These measures are adjusted to exclude certain charges and expenses discussed above and in the attached supplemental consolidated statements of operations, which the company believes are appropriate to enhance an overall understanding of its historical financial performance.  These adjustments to the company's current period 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 pro forma financial measures provides consistency and comparability with its historical reports of financial results, as well as comparability to similar companies in the company's industry, many of which present similar pro forma financial measures to investors.  In addition, these pro forma results 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.

Informatica will be discussing its first quarter 2004 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 69604579.
