Amentum on Monday said it has completed its acquisition of DynCorp International, creating a $6 billion services company serving federal, state, local and allied government markets.

Terms of the deal were not disclosed.

Amentum’s largest market sector is defense, followed by energy. DynCorp’s largest two customers are the Departments of Defense and State.

Amentum now has 34,000 employees working in 105 countries. Before the deal for DynCorp, the company estimated it would have about $4.3 billion in sales this year.

“The addition of DynCorp International will make us a powerhouse with an enduring mission focus and market-leading positions in several key areas,” John Vollmer, Amentum’s CEO, said in a statement. “The enhanced size, scope, and footprint of the combined organization will help ensure sustained delivery excellence to our customers and allow us to pursue transformational opportunities in the market.”

DynCorp provides Amentum with service capabilities in aviation maintenance and sustainment, training and fleet support, logistics, base operations support, asset management, maintenance repair and overhaul, and intelligence training. Amentum’s strengths are in mission support and equipment sustainment, information technology, intelligence, nuclear and environmental remediation, threat mitigation mission assurance, facility maintenance, and range services.

Amentum’s financial adviser on the deal was RBC Capital Markets. Citigroup and Morgan Stanley advised DynCorp.
