“The Company's business activities together with the factors likely to affect its future developments and position are set out in the Strategic Report on page 1. The Company has recorded a profit before tax in the current period. The Directors believe that the Company has enough resources to continue in operation for the foreseeable future. If the Company requires assistance to meet its financial obligations, Amentum Holdings LLC would be able to provide support to the Company.”
Significant events
- “The Jacobs Group completed a strategic restructuring, involving the spin-off and merger of its Critical Mission Solutions (CMS) and Cyber & Intelligence government services businesses with Amentum. This resulted in the creation of a new independent, publicly traded company. The Company was part of the group restructuring during the year, including the change in the immediate and ultimate parent ownership.”
- “On 30 September 2024, the Company changed its name from Jacobs Clean Energy International Limited to Amentum Clean Energy International Limited.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
