CSC INDICATES VALUE OF GROUNDBREAKER CONTRACT COULD EXCEED $5 BILLION

Computer Sciences Corporation (NYSE: CSC) today announced that the value of the Groundbreaker contract, awarded yesterday by the National Security Agency (NSA) to the Eagle Alliance, a CSC-led joint venture, could grow substantially if the agency expands the scope of the contract.

“With its current scope, the potential value of the contract exceeds $2 billion over a 10-year period if all options are exercised,” said Van B. Honeycutt, CSC’s chairman and chief executive officer. “If the scope is expanded, as anticipated, the potential value of the contract could exceed $5 billion.”

CSC is the managing partner of the Eagle Alliance, which was formed in partnership with Logicon, a Northrop Grumman company. The Eagle Alliance and its subcontractor companies will provide secure and non-secure telephony and network services, distributed computing services, and enterprise and security management of the non-mission information technology infrastructure at NSA headquarters and surrounding offices. When the contract takes full effect in November, CSC will assume responsibility for transitioning approximately 750 NSA employees into the Eagle Alliance and begin a modernization of the agency’s information technology infrastructure.
