Third Quarter 2025 Earnings Release For the period 1 January to 30 September 2025 Cadeler A/S. Incorporated in Denmark. Registration Number (CVR no.): 3118 0503 Kalvebod Brygge 43, DK-1560 Copenhagen V, Denmark

Financial Performance Income statement and cash flows The Group's revenue for the first nine months of 2025 was EUR 453 million, an increase of EUR 290 million compared to the EUR 163 million revenue reported for the comparable period in 2024, driven principally by the receipt of termination fees under the Long-Term Agreement (LTA) with Ørsted, and increased revenue from fleet expansion and higher utilisation. The Group’s cost of sales for the first nine months of 2025 was EUR 159 million, EUR 68 million higher than the comparable period in 2024, driven mainly by the addition of three new operating vessels to the fleet, Wind Maker, Wind Peak and Wind Pace. The Group’s eight operating vessels achieved a combined 75.8% utilisation rate for the first nine months of 2025, compared to 61.4% in the same period in 2024, where the Group had five operating vessels. The Group's EBITDA for the first nine months of 2025 was EUR 322 million, an increase of EUR 251 million compared to the EBITDA of EUR 70 million reported for the same period in 2024, as disclosed in the Alternative Performance Measures (APM) section. For the first nine months of 2025, the Group’s result was a profit of EUR 232 million, an increase of EUR 205 million relative to the EUR 28 million profit reported for the comparable period in 2024. The Group’s increased result was principally driven by higher gross profit for the period, principally due to receipt of termination fees in respect of the LTA and an increase in operating vessels in the period along with an increase in vessel utilisation. Net cash flow provided by operating activities was EUR 286 million in the first nine months of 2025, EUR 241 million higher than the EUR 45 million recorded for the comparable period in 2024, driven by increased operating profit and an increase in deferred revenue from advance customer payments, partially offset by an increase in trade and other payables. Net cash flow used in investing activities in the first nine months of 2025 was EUR 931 million, an increase of EUR 382 million compared to the EUR 549 million reported for the same period in 2024. This increase was driven by the final instalment payments made for the three newbuild vessels delivered in the first nine months of 2025, Wind Maker, Wind Pace and Wind Ally, as well as the purchase of Wind Keeper. Net cash flow provided by financing activities in the first nine months of 2025 was EUR 805 million, an increase of EUR 303 million compared to the EUR 502 million reported for the comparable period in 2024. This increase was driven by proceeds from borrowings of EUR 883 million net of bank fees and partially offset by the increased interest paid and repayments. Outlook 2025 These results are above expectations and in line with the company’s recently updated full-year revenue and EBITDA guidance, which was revised on 1 July 2025 to reflect increased earnings visibility. Cadeler today reaffirms that guidance, with full-year revenue expected to range between EUR 588 and 628 million and EBITDA between EUR 381 and 421 million. This earnings release report for the period 1 January to 30 September 2025 is neither audited nor reviewed. Subsequent Events On 17 October 2025, Cadeler repaid the Wind Keeper Bridge Facility of EUR 150 million in full, funded by the drawdown on the same date of the full amount of the EUR 125 million Wind Keeper Facility together with EUR 25 million cash on hand. ________________ 2 "Strong performance with high utilisation, improved earnings and continued fleet expansion"

Financial Performance Continued from previous page Capital and assets As of 30 September 2025, the Group’s total assets amounted to EUR 3,056 million, a 58% increase compared to 31 December 2024. This increase was driven primarily by an increase in property, plant and equipment of EUR 914 million, which was attributable to the Group’s newbuild programme, including the delivery of the new M-Class vessel, Wind Maker, the new P-Class vessel, Wind Pace, and the Group's first A-class vessel, Wind Ally, as well as the acquisition of the Wind Keeper. The Group's equity amounted to EUR 1,446 million as of 30 September 2025, reflecting an increase of EUR 212 million from the balance at year end 2024 of EUR 1,234 million. The development in the Group's equity was driven by a loss of EUR 15 million from adjustment of hedges along with EUR 5 million in costs relating to the hedges, offset by a profit of EUR 232 million and share-based payments of EUR 2 million for the first nine months of 2025. As of 1 January 2025, all entities of the former Eneti Group have changed their functional currency from USD to EUR. The change is driven by Cadeler’s acquisition of the former Eneti Group at the end of 2023, and the subsequent changes to the financing, organization and activities of the entities formerly associated with the Eneti Group, following which the Group's Management has made the assessment that the primary economic environment in which each of the entities now operates has changed to be principally denominated in EUR. Accordingly, Management has determined that EUR is the new functional currency that will most faithfully reflect the underlying transactions, events and conditions relevant to the entities formerly associated with the Eneti Group following the acquisition. As some of the group entities are conducting business in an international environment, Management has applied judgement to determine the primary economic environment considering the Group's underlying transactions, events and conditions.

Forward-Looking Statements The annual report, as referred to in this document, and this earnings release, contain certain forward-looking statements relating to the business, financial performance, and results of the Company and/or the industry in which it operates. Forward-looking statements concern future circumstances and results and other statements that are not historical facts, sometimes identified by the words “believes”, expects”, "predicts", "in-tends", "projects", "plans", "estimates", "aims", "foresees", "anticipates", "targets", and similar expressions. The forward-looking statements contained in the annual report and this earnings release, including assumptions, opinions and views of the Company or cited from third party sources are solely opinions and forecasts which are subject to risks, uncertainties and other factors that may cause actual events to differ materially from any anticipated development. Such factors may for example include a change in the price of raw materials. None of the Company or any of its parent or subsidiaries undertakings or any such person's officers or employees provides any assurance that the assumptions underlying such forward-looking statements are free from errors nor does any of them accept any responsibility for the future accuracy of the opinions expressed in the annual report or the actual occurrence of the forecasted developments. The Company assumes no obligation, except as required by law, to update any forward-looking statements or to conform these forward-looking statements to its actual results. The annual report and this earnings release may contain information obtained from third parties. You are advised that such third-party information has not been prepared specifically for inclusion in the annual report or this earnings release and the Company has not undertaken any independent investigation to confirm the accuracy or completeness of such information. Several other factors could cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements that may be expressed or implied by statements and information in the annual report or this earnings release.

Alternative Performance Measures Non-IFRS Financial Measures To supplement its financial information presented in accordance with IFRS, the Group uses certain non-IFRS metrics, including EBITDA, when measuring performance, including when measuring current period results of operations against prior periods. Because of its non-standardised definition, these non-IFRS measures (unlike IFRS measures) may not be comparable to the calculation of similar measures of other companies. These supplemental non-IFRS measures are presented solely to permit investors to more fully understand how management assesses underlying performance. These supplemental non-IFRS measures are not, and should not, be viewed as a substitute for IFRS measures. Management believes the presentation of these non-IFRS measures provides investors with greater transparency and supplemental data relating to the Group’s financial condition and results of operations, and therefore a more complete understanding of factors affecting its business and operating performance. In addition, Management believes the presentation of these non-IFRS measures is useful to investors for period-to-period comparison of results as the items may reflect certain unique and/or non-operating items such as asset sales, write-offs, contract termination costs or items outside of Management’s control. As a performance measure, the Group used EBITDA: Earnings before interest, tax, finance income/costs and depreciation and amortisation. EBITDA is calculated as shown below: EUR'000 9M 2025 9M 2024 Operating profit or loss as reported in the statement of profit 247,637 31,841 Right-of-use asset amortisation 1,297 1,051 Depreciation and amortisation 72,634 37,266 EBITDA 321,568 70,158 ________________ 12
