1H 2025 Results Presentation

Attilio Ievoli

Chairman of NextGeo

"The first half of 2025 marks another step forward for NextGeo group. We have achieved excellent results thanks to disciplined execution, a strong focus on value creation and an operating model that prioritises safety, data integrity and reliability.

What we achieved reflects the commitment of our people and the trust of our customers, earned project by project in demanding offshore environments. Our strategy is clear: we invest where our capabilities make the difference and we develop the resources that support performance over time. In the first half of 2025 we continued to invest selectively, strengthening our fleet, our systems and our technical capabilities, so that today's results match the capabilities required tomorrow. Safety, rigour and service quality remain the pillars of our operating model and the reason why customers rely on us for complex offshore projects.

Within this framework we refined our business mix. Interconnectors and offshore renewables remains our core, while we are raising our share in Oil&Gas through measured strategic actions. We recently completed the acquisition of Rana Subsea, broadening our subsea offering and enabling support across the full life cycle of offshore assets, from surveys and engineering to IMR. We also established a regional hub in the Middle East to be closer to customers and partners and to pursue a wider range of opportunities in this strategic area.

These choices are consistent with the way we lead the company. We pursue growth that is sustainable, we allocate capital with discipline and we set demanding standards for health, safety and the environment and we continue to invest in talent and technology. This is how we convert market opportunities into dependable performance and how we build our resilience."
