Amentum (company)

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.{{cite web |url=https://aecom.com/management-services-sale/ |title=Management Services Sale |author=AECOM |work=Press Releases |date=2020-01-30 |access-date=2022-07-06 }}

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.{{cite web |url=https://www.amentum.com/corporate-lineage/ |title=Corporate Lineage |publisher=Amentum |access-date=2022-07-06 }}
