The National Institutes of Health (NIH) has awarded Evolvent Technologies, a wholly-owned subsidiary of ManTech International Corporation (NASDAQ:MANT), a prime contract to provide IT services and solutions for the NIH Health Information Technology Acquisition and Assessment Center (NITAAC). The Governmentwide Acquisition Contract (GWAC) is a 10-year Indefinite Delivery, Indefinite Quantity (IDIQ) contract with a total ceiling value of $20 billion for all awardees. NITAAC’s mission is to provide quality IT products and services through the use of innovative GWACs in support of federal agencies in an efficient and economical manner. Under 10 task areas on the Chief Information Officer-Solutions and Partners (CIOSP-3) contract, Evolvent will support NITAAC with a range of professional IT and support services including health, health science and biomedical-related IT services to meet scientific, health, administrative, operational, managerial, and information management requirements. "We are pleased to provide innovative IT services and solutions in support of the NIH mission,” said Terry M. Ryan, president and chief operating officer of ManTech’s Emerging Markets Group (EMG). "Evolvent maintains the requisite health, biomedical, cyber and large-scale IT development and integration skills and experience to help make NITAAC projects successful. Our high-end engineers, analysts and subject matter experts will provide innovative approaches to implementation and are dedicated to support the NITAAC mission for all their program requirements.” “ManTech’s commitment to the emerging Health IT sector was validated through our acquisition of Evolvent earlier this year. We are very gratified that this strategy has been borne out so quickly in the award of this $20 billion GWAC,” stated ManTech Chairman and CEO George J. Pedersen. Mr. Pedersen went on to say, “These types of promising opportunities are the reason and means for establishing the Emerging Markets Group under our new organizational structure.” About ManTech International Corporation ManTech is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the Department of Defense, including health organizations; the departments of State, Homeland Security, Energy and Justice, including the Federal Bureau of Investigation (FBI); the space community; the National Oceanic and Atmospheric Administration; and other U.S. federal government customers.
