Jan De Nul Group recorded a turnover exceeding €4.2 billion ($4.9 billion) for the financial year ending December 31, 2025.
This performance represented a six per cent increase compared to 2024, supported by activities across its four business units.
According to financial statements, the Luxembourg-based maritime infrastructure company generated a net profit of €458 million, marking a 12 per cent rise over the previous year. Its order book stood at €7.85 billion at the end of December 31, 2025.
Europe remained the largest market for the company, accounting for nearly 54 per cent of its turnover and representing a growth of more than 30 per cent compared to 2024. African operations also increased significantly, driven in part by the construction of a new deep-water port in Senegal.
"This diversification acts as a buffer against the current geopolitical climate, which is causing significant uncertainty worldwide," explained Jan Neckebroeck, Chief Financial Officer of Jan De Nul Group. He noted that international tensions, diplomatic uncertainty and rising energy prices are putting the brakes on client investment programmes.
To support future projects, Jan De Nul is constructing two cable-laying vessels, Fleeming Jenkin and William Thomson, which are scheduled to join the fleet in 2026. The company also ordered a trenching support vessel named Isambard K. Brunel to bury subsea cables.
