Amentum

Amentum is the U.S. government services company that spun off from AECOM.¹ It is part of the team managing and operating the Lawrence Livermore National Laboratory² and has performed readiness assessment at the Los Alamos National Laboratory,³ responsible for nuclear weapons design and maintenance.⁴ Amentum also has an outstanding contract to support missile testing for U.S. nuclear weapon programmes.⁵ The company is also involved in nuclear waste storage at several facilities in the U.S. and UK, as well as environmental remediation.⁶ When launched as an independent company in 2020, Amentum became privately held, with the equity firms American Securities and Lindsay Goldberg as equal partners.⁷ However, in November 2023, Amentum announced a merger agreement with Jacobs Solutions’ Critical Mission Solutions (CMS) and Cyber & Intelligence (C&I) Businesses, where the combined organization will be a publicly traded company.⁸  Both Jacobs Solutions and Amentum are rumoured to be among the competing candidates for the new management contract of the Pantex Plant⁹ after the U.S. Department of Energy had terminated the contract award to Nuclear Production One, a joint venture between Amentum and Fluor, in 2021.¹⁰
