The year-to-date performance is fueled by a double-digit year-to-date growth in the Offshore Energy segment which more than offset softer topline results in other segments compared to strong prior year revenues. 1 Order book refers to the contract value of assignments acquired at the end of the respective reporting period, which have not yet been accounted for as turnover because of non-completion. This amount includes DEME’s share in the order book of joint ventures but excludes that of associates. Contracts are not included in the order book until the agreement with the client is signed. 2 The reconciliation between the segment turnover and the turnover as per financial statements refers to the turnover of joint ventures. They are consolidated according to the proportionate consolidation method in the segment reporting but according to the equity consolidation method in the financial statements.

3/6 DEME Group | Scheldedijk 30, 2070 Beveren-Kruibeke-Zwijndrecht, Belgium | www.deme-group.com Outlook 2025 The following statements are forward looking, and actual results may differ materially. Given the year-to-date performance, DEME’s management reiterates its expectations that full- year turnover will be at least in line with 2024 and forecasts a strong year-over-year EBITDA improvement, with the EBITDA margin in the range of 20% to 22%. Full year CapEx remains forecasted at approximately 300 million euros, excluding the expenditure for the Havfram acquisition and the completion and delivery of its two vessels, representing a total transaction value of about 900 million euros. Strategic developments DEME took delivery of its new offshore installation vessel Norse Wind, on schedule. The construction of Norse Wind was initiated in 2023 by Havfram, the Norwegian offshore wind contractor acquired by DEME in April this year. The vessel sets a new standard in lifting capacity, speed and efficiency and will reinforce DEME’s leading position in the global offshore energy market. Norse Wind is set to commence operations in the first half of 2026, starting with offshore wind projects in Europe. The sister vessel Norse Energi is scheduled for delivery in early 2026. Furthermore, DEME announced the expansion of its fleet with a new offshore construction vessel, enhancing its subsea trenching and cable installation capacity to meet the needs of the evolving global offshore wind market. The vessel is scheduled for delivery in 2028. OPERA TING SEGMENTS Please find below a description of the performance of DEME’s operating segments in the third quarter of 2025.
