Quarterly revenue remained stable at $1.84bn.

Record-high order backlog

The group’s order backlog reached a record $13.91bn at the end of September, up from $11.82bn three months earlier. This amount includes $6.0bn of projects scheduled for execution in 2026 and $3.8bn planned for 2027.

Over the first nine months of the year, Subsea7 generated cumulative revenue of $5.13bn, up from $4.97bn in the previous year. Adjusted EBITDA for the period reached $1.00bn, representing a 20% margin.

Positive outlook for 2026

For the full year 2025, Subsea7 expects revenue between $6.9bn and $7.1bn, with an adjusted EBITDA margin projected between 20% and 21%. Based on firm contracts already signed for 2026, the company anticipates revenue in the range of $7.0bn to $7.4bn and an adjusted EBITDA margin of approximately 22%.

The group maintains a strong financial position, with net debt including lease liabilities reduced to $505mn, representing 0.4 times the adjusted EBITDA over the last twelve months. Cash and cash equivalents increased to $546mn, while gross borrowings slightly decreased to $629mn.
