PURINA MILLS, INC. BOOSTS SALES AND MAXIMIZES MANUFACTURING EFFICIENCY WITH ERP ANALYTIC SOLUTION FROM INFORMATICA

Nation's largest animal-feed producer successfully integrates ERP, historical data to provide key decision-makers with valuable business intelligence

PALO ALTO, Calif., May 8, 2000 - Informatica Corporation (NASDAQ: INFA), one of the leading providers of integrated analytic solutions for e-business, today announced the successful implementation of its PowerCenter™, PowerConnect™ for SAP™ R/3® and Business Components™ for SAP R/3 data-integration software products at Purina Mills, America's largest producer of animal nutrition products. The ability to access and integrate critical enterprise resource planning (ERP) data from its SAP R/3 system with historical data from the company's legacy mainframes has helped Purina Mills effectively perform trending and forecasting analysis that has translated into improved sales and manufacturing efficiency across the company.

With valuable historical information stored across the company in legacy mainframe systems and more current data locked in SAP R/3, Purina Mills, Inc. recognized in 1999 that it needed an integrated solution that would deliver critical business information to analysts without requiring complex, expensive and time-consuming manual data integration.

"We had a clear business mandate to provide our sales and marketing analysts with powerful and flexible reporting capabilities, but recognized that retrieving data from SAP R/3 for analysis can be a difficult, time-consuming process," said John Lochner, manager of data services at Purina Mills. "To compound this challenge, we also needed to integrate our R/3 data with a wealth of historical data from the company's legacy systems to ensure accurate reporting."

After evaluating numerous point solutions for extracting ERP data, Purina Mills chose a comprehensive enterprise-data-integration solution from Informatica by combining its PowerCenter, PowerConnect for SAP R/3 and Business Components for SAP R/3 software. The company now has access to a consolidated view of sales, distribution, materials management, production and financial information that helps fuel strategic analysis across the company.

"Informatica provided us with an efficient, effective solution that allows us to do our jobs more effectively and with a higher degree of credibility," said Lochner. "Our analysts can now examine sales, manufacturing and operations data down to the invoice line-item level -- something we previously couldn't do."

Informatica's PowerCenter is an enterprise data-integration hub that enables large organizations to easily transform legacy, relational and ERP data into reliable information for strategic business analysis. PowerConnect for SAP R/3 software helps companies directly access the vast amounts of corporate data stored in their R/3 ERP system for business intelligence. Business Components for SAP R/3 software helps speed and simplify the complex process of extracting ERP data.
