Higher-than-expected business volumes

Year-to-date revenue at 30 September 2026 stood at €425.4 million, a year-on-year increase of 18.8% (18.7% at constant currency²).

In the third quarter, business volumes generated €150.2 million, a 23.5% increase that reflects the Group’s accelerated growth.

These results come from the Group’s high-quality portfolio of contracts, the strong performance of its major contracts, and its ability to scale operations with complementary services in complex and remote environments.

New contracts signed in certain regions also underpinned this growth.

In 2026, exchange rates have had very little impact on business growth and now show a positive difference of €0.3 million.

Business was driven by the strong performance in Africa (up 16% at constant currency²) and Eurasia (up 24% at constant currency²). In the Americas, the business decline is now limited to 6% with new contracts signed and new platforms commissioned by privately-owned companies in Brazil’s offshore sector.
