ManTech International Corp. of Fairfax led local gainers last week after the information technology company said one of its joint ventures won a State Department contract for $40 million.

MSM, a private firm that conducts background investigations for security clearances, was acquired last month by ManTech International. Under the five-year contract, ManTech Solutions is to help conduct security investigations for the State Department's Bureau of Diplomatic Security.
