CSC WINS $16 MILLION CONTRACT TO SUPPORT TRANSPORTATION SECURITY ADMINISTRATION

EL SEGUNDO, Calif., Feb. 22 - Computer Sciences Corporation (NYSE: CSC) announced today that it has won a contract to provide adjudication support services to the U.S. Department of Homeland Security’s Transportation Security Administration (TSA). CSC estimates the value of the contract, which has one base year and three one-year options, to be approximately $16 million if all options are exercised.

This award emphasizes our extensive experience and ability to deliver results that protect critical infrastructure.”

CSC and subcontractor Trinity Technology Group Inc., of Fairfax, Va., will provide approximately 40 security adjudication professionals to provide support services, primarily in the Washington, D.C., metropolitan area.

The TSA is responsible for protecting the nation’s transportation systems to ensure freedom of movement of people and commerce.
