Leidos (NYSE: LDOS) has agreed to purchase IMX Medical Management Services, a consulting firm that provides independent medical assessment, case management, and file review services to state and local government agencies.

Terms of the deal were not disclosed, and Leidos said Wednesday it expects the deal to close in the third quarter, pending customary approvals.

IMX, headquartered in Malvern, Pennsylvania, will become a subsidiary of QTC Management, which Leidos acquired as part of the 2016 Reston, Virginia-based contractor’s acquisition of the information systems and global solutions business of Lockheed Martin (NYSE: LMT).

QTC, which carries out medical examinations and data evaluations for federal customers in the healthcare sector, will take over almost 200 employees through the takeover.

Jon Scholl, president of Leidos Health Group, said the company has 35 years of experience providing technology-based testing services through QTC.
