FROM THE EXECUTIVE VICE-CHAIRMAN AND THE CEO

Johan Beerlandt

Executive Vice-Chairman

Pierre Sironval

Chief Executive Officer

In 2025, the environment around us remained unsettled. Economic pressure, geopolitical tension and increasingly demanding clients continued to shape the way we operate. That uncertainty did not disappear during the year, but it sharpened our attention for clarity, discipline and strong teamwork.

It was also a year of progress, supported by deliberate choices. We were selective in the projects we pursued, careful in how we managed risk, and consistent in our focus on delivering safely, responsibly and to a high standard. That focus made a difference.

For BESIX Group, 2025 was not about growth at any price. It was about strengthening the fundamentals of the business. We did grow, but with a clear understanding of where we create value and where restraint is needed. This shared mindset across the Group improved our financial resilience and allowed us to continue delivering complex projects in demanding settings.
