Equifax to Acquire IXI Corporation

Atlanta — October 21, 2009 — Equifax Inc. (NYSE:EFX) announced today it has reached a definitive agreement to acquire IXI Corporation, a leader in collecting, analyzing and delivering consumer wealth and asset data. Equifax will pay $124 million in cash for the company.

With its proprietary measures of wealth, assets, income, spending and other data, IXI helps its clients better segment households, resulting in improved marketing and customer management. IXI’s client base includes leading companies in the financial services industry (such as banks and brokerage firms) and emerging opportunities in the insurance and healthcare industries.

IXI’s data, sourced through more than 95 leading banks, brokerage firms and other financial entities, is the most comprehensive database of invested and deposited consumer wealth in the country. IXI directly measures data on more than $10 trillion in U.S. consumer assets and investments, representing more than 42 percent of all U.S. consumer invested assets.

“Bringing together the differentiated data and analytic capabilities of each of the companies will allow us to deliver a deeper view of the consumer that includes wealth, credit, income, spending and other demographic data ,” said Dann Adams, president, Equifax Consumer Information Solutions. “The caliber and breadth of intelligence and data we’ll offer will significantly improve the opportunities for our clients to acquire, expand and retain customer relationships.”

“We have worked closely with Equifax over the last 18 months and know their people, the solutions they offer, and their culture. I am convinced this will be a strong combination that will benefit customers and employees of both companies,” said Tom Dailey, president and CEO of IXI.

IXI’s unique capabilities combined with Equifax’s expertise will allow the companies to offer more differentiated and in-depth income, wealth and other data, helping companies improve their marketing, collections, portfolio monitoring and customer management efforts across all product segments.

“This is a good match and our companies know each other well from a history of collaboration. Each of the companies excels in its particular area of the business; the skills and knowledge are complementary; and we serve similar customer bases,” said Adams. “But the biggest beneficiaries will be our clients, who will have broader, deeper and more accurate customer information backed by a company with a strong tradition of protecting the security and integrity of the data entrusted to us.”

The closing of the transaction is subject to the usual conditions and is expected to occur in the near future.

IXI was advised in the transaction by Wells Fargo Securities.
