ManTech to acquire Definitive Logic

ManTech International Corp. on Tuesday signed an agreement to acquire Arlington County-based Definitive Logic in a deal that will add 330 employees to the Herndon-based federal contractor’s workforce.

Financial terms of the deal were not disclosed.

Definitive Logic provides digital transformation consulting services and technology to defense, Homeland Security and federal civilian agencies. In a news release Tuesday, ManTech said the addition of Definitive Logic’s employees will expand the federal contractor’s suite of cloud, cyber, DevSecOps (development, security and operations) data engineering and artificial learning/machine learning capabilities as well as technology partnerships.

“With mission expansion and technology cycles accelerating at speed, our government customers rely on ManTech to bring our mission knowledge with our mastery of high-tech, high-end engineering, cyber and data solutions to solve their toughest security challenges,” ManTech CEO and President Matt Tait said in a statement. “Definitive Logic’s differentiated consulting and tailored technology solutions will further advance ManTech’s mission-focused strategy — ‘Bringing Digital to the Mission.’ We are very pleased to welcome their highly talented team, sophisticated capabilities and valued government customers.”

The acquisition is expected to close in early fall. ManTech provides technology solutions for U.S. defense, intelligence and federal civilian agencies. The company was acquired by The Carlyle Group for about $4.2 billion in September 2022. Tait succeeded former President and CEO Kevin Phillips, who retired and transitioned to chair of ManTech’s board soon thereafter.

Definitive Logic will maintain its Arlington office, company spokesperson Sheila S. Blackwell told Virginia Business in an email. Co-founder and CEO Paul Burke will lead the team and be part of ManTech’s growth and innovation organization, Blackwell said.

“For more than 20 years, Definitive Logic has earned its reputation as a trusted partner of government change agents,” Burke said in a statement. “We are proud of the transformation outcomes we have consistently delivered for the warfighter and taxpayer and are thrilled to double down on innovation and expand our capabilities as part of ManTech. … We look forward to capitalizing on the significant growth that both our company and employees will enjoy as part of a combined platform with enhanced scale, breadth, resources and career opportunities.”
