QuantiTech, a portfolio company of Sagewind Capital, has acquired Systems Engineering Group (SEG), of Columbia, from Griffon Corp. Financial terms of the transaction were not announced.

SEG is a provider of threat engineering and modeling and simulation services to the U.S. Government, primarily supporting the Naval Surface Warfare Center, Missile Defense Agency and Office of Naval Intelligence. The company provides advanced, physics-based threat modeling, engineering, and analytics services in support of U.S. Government requirements for weapons and missile systems development, simulation, testing, and analysis. The management team and employees of SEG will continue with the business as a part of QuantiTech.

“This combination brings together two companies with an extraordinary depth of talent and expertise in high-end engineering,” said Randy Cash, chairman of the board of QuantiTech. “By strengthening our capabilities in the missile defense, hypersonics and intel markets, we will be even better positioned to continue serving the important missions of the U.S. Government.”
