Amentum (company)

Amentum Services, Inc. (formally Amentum Government Services Holding LLC) is an American government and commercial services contractor based in Chantilly, Virginia. The company was formed in 2020 from the spinout of AECOM's Management Services / federal group. After Leidos, it is the second-largest government services (non equipment producing) contractor in the US government contracting market.

History
Amentum was founded in 2020 as a spinout of the Management Services Group of AECOM, consisting of the non-construction parts of the company's federal work as well as its commercial operations and maintenance business. This came as a result of a process by AECOM to realign its business to focus more clearly on the architect, engineering, and construction market.

Amentum traces its AECOM roots back to several well-known government contracting firms that now form the basis of its current work. These firms came to be a part of the company by way of AECOM's acquisition of URS Corporation and include EG&G, Washington Group International, Westinghouse Government Services, and Lear Siegler.

Growth through acquisitions
As part of the strategy by its owners, Amentum has pursued acquisitions of other government contractors including:
 * 2020 - DynCorp
 * 2022 - PAE
