“The Directors consider that the going concern assumption remains appropriate for the Company. In forming that conclusion, the Directors have taken into consideration the potential completion of the proposed merger with Saipem S.p.A. The Directors consider that there are no significant doubts over the application of the going concern assumption and no disclosable material uncertainties which cast doubt upon the Company's ability to continue as a going concern.”
Significant events
- “On 23 February 2025, Subsea 7 S.A., the ultimate parent company of the Group, announced an agreement in principle on the key terms of a proposed merger with Saipem S.p.A. Merger discussions are ongoing with the completion of the proposed combination anticipated to occur in the second half of 2026.”

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
