Acquisition Expands CA’s Presence in Emerging Enterprise and MSP Markets. Nimsoft to Operate as a Standalone Business Unit Within CA’s Cloud Business Line

ISLANDIA, N.Y, March 17, 2010 – CA, Inc. (NASDAQ:CA) today announced it has completed its acquisition of privately-held Nimsoft, Inc.—a leading provider of IT performance and availability monitoring solutions for emerging enterprises and Managed Service Providers (MSPs)—for $350 million in an all-cash transaction.

The acquisition significantly extends CA’s ability to meet the unique IT management needs of emerging enterprises and MSPs, both of which are playing leading roles in the growth of cloud computing. Nimsoft’s technology and go-to-market approach also will leverage CA’s presence in growing international markets—where the Company expects cloud computing and hosted/managed services to play a central role in business development.

“We believe that the acquisition of Nimsoft by CA will result in enhanced monitoring solutions in the area of hosted/managed services,” said Kevin Crowe, Director of Managed Services of Long View Systems. “Nimsoft technology, combined with CA’s commitment to cloud computing, will provide us with a robust solution that will allow us to create more value for our clients and will enable us to continue to evolve and innovate as an MSP.”

The acquisition also will extend CA’s leadership position in the Service Assurance market segment, offering one of the most comprehensive suites of IT monitoring and management solutions in the industry.

Nimsoft will operate as a standalone business unit within CA’s Cloud Products & Solutions Business Line.
