Amentum

Amentum is the US government services company that spun off from AECOM.¹ It is part of the team managing and operating the Lawrence Livermore National Lab² and the Los Alamos National Lab for US nuclear warhead production and maintenance.³ Amentum also has contracts to support missile testing for US nuclear weapon programmes.⁴ The company is also involved in nuclear waste storage at several facilities in the US and UK, as well as environmental remediation.⁵ Amentum is not publicly traded and is a privately held company where the equity firms American Securities and Lindsay Goldberg are equal partners.⁶ In November 2021, Nuclear Production One, a joint venture between Amentum and Fluor, was awarded the contract to manage and operate the Y-12 National Security Complex and the Pantex Plant, ⁷ yet this contract award was terminated in May 2022 when the US Department of Energy announced it would hold two new competitions for separate contracts to manage each site.⁸
