Amentum Holdings, Inc. (formally Amentum Government Services Holding LLC) is an American government and commercial services contractor based in Chantilly, Virginia.[5][6] The company was formed in 2020 from the spinout of Aecom's Management Services / federal group.[7] After Leidos, it is the second-largest government services (non equipment producing) contractor in the US government contracting market.[8]

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.[9]

In March 2024, Amentum announced the completion of its merger with Jacobs Solutions.'s Critical Mission Solutions and Cyber and Intelligence businesses.[10] In September of that year, it became a publicly traded company on the NYSE under the ticker symbol "AMTM", becoming a part of the S&P 500.[11]

On April 23, 2025, Lockheed Martin announced it had agreed to buy Amentum's Rapid Business Solutions Business for $360M [12] The deal was closed in June 2025.[13]

Growth through acquisitions

As part of the strategy by its owners, Amentum has pursued acquisitions of other government contractors including:
