With a 36% increase in turnover compared to 2023, it seemed challenging to surpass 2024. Nevertheless, turnover in 2025 rose again by 6% and net profit by a significant 12% compared to 2024. CFO Jan Neckebroeck: “We are prepared for the future.”
With a total turnover of €4.24 billion, we recorded a 6% increase compared to 2024. EBITDA rose from €777 million in 2024 to €812 million in 2025, following the same trend. Net profit rose by 12% to €458 million.
Maritime construction projects
The maritime sector accounts for 74% of our turnover. This includes the construction of offshore wind farms, the installation of subsea cables to transport energy, the maintenance of access channels and the expansion of port infrastructure.
Our various construction, remediation and redevelopment projects represent 26% of turnover. In 2025, we completed the infrastructure works for the F-35A fighter jets at Florennes Air Base, ahead of the aircraft’s arrival on Belgian soil in October 2025. Other major projects include the Oosterweel link, the new traffic junction near Brussels Airport, the energy island in the Belgian North Sea and the development of the new ‘MALT’ district in Mechelen.
CFO Jan Neckebroeck: “Jan De Nul remains active worldwide with maritime infrastructure projects, covering both offshore energy and dredging works. The various construction, remediation and redevelopment projects have also contributed to achieving another record turnover. Jan De Nul’s strong financial position, including a net debt-free position, allows us to invest in new vessels, land-based equipment and research. We are prepared for the future.”
Geographical diversification as a buffer
We achieved this turnover through a broad geographical spread, with 298 projects in 31 countries. More than 50% of our turnover comes from Europe, mainly because of a large portfolio of offshore wind energy projects. The construction of a new port in Senegal contributed significantly to the increase in turnover in Africa. The Middle East, North and South America, and Asia also remain important markets.
Over a billion euros in investments
With five new vessels for the installation and protection of subsea power cables on the way, we are making major investments to strengthen our position as a key player in the energy sector. In doing so, we are anticipating to the global need for energy security, which is driving different regions around the world to develop a balanced energy mix and to interconnect energy grids.
In addition, we continue to invest in the expansion and renewal of our dredging fleet and focus on innovative remediation techniques to tackle complex contamination, such as PFAS. As a long-standing partner of the Belgian government, we also continue to focus on the development of infrastructure. The ongoing investments for the coming years are worth well over a billion euros.
Reinvesting profits
Despite this wave of investment, we are net debt-free since 2014. As a privately held company, we consistently reinvest our profits back into the business. This financial strength is one of our key assets.
Jan Neckebroeck: “But our greatest asset remains our global team of more than 8,800 World Builders. We continue to invest in them as well. We do this, among other things, through our four internal programmes on safety, personal development, sustainability and health, which we launched in 2025. Our company’s culture makes our positive impact tangible worldwide.”
