ST. LOUIS, June 27, 2008 (PRIME NEWSWIRE) -- The U.S. Department of Defense (DoD) has selected Express Scripts as the contractor for the DoD's TRICARE Pharmacy Program serving 9.1 million DoD beneficiaries.

"It is a great honor to continue serving our men and women in uniform, along with their dependents and military retirees -- to work on their behalf making the use of prescription drugs safer and more affordable. We look forward to continuing to meet beneficiaries' needs with outstanding service," said George Paz, chairman and chief executive officer of Express Scripts.

Paz added that "this contract award reaffirms Express Scripts' differentiated business model of aligning with clients and patients, and driving to lowest net cost while enabling better health and value one consumer at a time."

Under current DoD contracts, Express Scripts has consistently received high service ratings and secured performance incentives every consecutive quarter in providing home delivery services, and annually on retail pharmacy services.
