ManTech International, a Fairfax-based defense contractor, has agreed to acquire Columbia-based healthcare IT firm 7Delta.

Financial terms of the deal, expected to close in May 2014, were not disclosed, though ManTech plans to fund the deal mainly from cash on hand. ManTech is scheduled to announce its first quarter earnings for the 2014 fiscal year on Wednesday night.

Defense contractor 7Delta provides software development, program management, information assurance and other technical services to defense and civilian customers in the federal government, including the Department of Veterans Affairs.

“ManTech made a strategic commitment to the healthcare IT market, and upon completion of this acquisition, we will have strong capability and presence across the entire spectrum of federal healthcare, including the VA, [Defense Department], and Health and Human Services,” ManTech chairman and chief executive George J. Pedersen said in a statement.

This is ManTech’s second acquisition in recent months. February, the company acquired Allied Technology Group, a Rockville-based engineering and information management solutions firm contracting with the Homeland Security Department.

Tysons-based investment bank KippsDeSanto advised and represented 7Delta in the transaction.
