The solid progress we are making is also cautiously reflected in our Q3 results: production, contribution and EBITDA all slightly improved on the previous quarters. The modifications to the production lines are performing as we expected and our focus is now on the continuation of the upward trend that will gradually bring us to the projected levels of production. We therefore maintain de guidance provided at the release of our Q2 numbers. Our orderbook is filled with firm contracts for 2026 and we expect more clarity on the exclusive negotiations for the 200 Kton orderbook position for 2027 in Q1 2026. The market remains challenging with a limited number of new tenders, and the United Kingdom and European countries struggling to run successful large-scale tenders. The upcoming CfD7 round in the UK is expected to see only 5-6 GW out of the potential 21 GW projects awarded, given the lower-than-expected subsidy allocation of £900 million. In a joint effort, European countries and the European Union are looking for ways to speed up grid connection and to facilitate the demand for and offtake of green energy. The European Parliament is pursuing countermeasures for a level playing field for offshore wind supply chain partners and for a tender approach that is more balanced than the recent tenders. All to maintain momentum for the energy transition, energy independence and the reduction of greenhouse gas emissions. Decision making speed and effective roll out of EU measures in EU member states is of the essence to regain momentum in the offshore wind market. Our intensified efforts to reduce the number of safety incidents and sick leave have paid off. In H1 2025 we experienced 7 LTI’s, and the YTD total now stands at 8 following one LTI incident in September. We will continue to keep focus on these important people related KPI’s to assure a sustainable safe and healthy working environment in line with our targets”. Trading Update 7 November 2025 Roermond, the Netherlands Q3 2025 and YTD Results Contribution Contribution is a better indicator for performance than revenues since it eliminates changes in steel prices and ignores legal structures for cooperation. For the first nine months of 2025 contribution added up to €128 million of which €1 million relates to Marshalling and Logistics services and €8 million relates to other activities, including Engineering services (€111 million of which €1 million for Marshalling and €7 million for other activities, including Engineering services in first nine months 2024). Contribution, adjusted for contribution from Marshalling, Engineering services and fees for projects without production volume, of €13.4 million per month and €969 per ton improved on the contribution per month and per ton in the same period of 2024 when it stood at €10.1 million and €712 per ton respectively. Earnings Adjusted EBITDA in Q3 2025 amounted to €13.8 million (€5.2 million in Q3 2024). Non-recurring expenses relating to the expansion of our manufacturing facilities amounted to €3.7 million in the third quarter (€3.2 million in Q3 2024), resulting in a reported EBITDA of €10.1 million (€2.0 million in Q3 2024). Reported EBITDA was positively impacted by the release of provisions for liquidated damages in projects. Financial position Net working capital was -/-€160. million ( -/-€180.8 million at the end of Q2 2025). Total cash position decreased to €55 million at the end of Q3 2025 from €82.5 million at the end of Q2 2025. Banking covenants require solvency of 35% and maximum net leverage of 3.00x. Solvency at the end of Q3 2025 with 35.0.% was compliant but the negative LTM EBITDA (adjusted to exclude exceptional items (ex IFRS 16)) results in net leverage which cannot be determined. We have therefore agreed a waiver with the banking consortium for the leverage covenant Q3 2025. Furthermore, in light of the ongoing ramp-up of our production, we have agreed to an amendment of the leverage and solvency covenants for the period Q4 2025 and Q1 2026. In addition, a minimum EBITDA covenant has been introduced for these two quarters, as reflected below: Covenant Q4 2025 Q1 2026 Solvency 25% 30% Leverage 6.0x 3.5x Minimum Adjusted EBITDA €10m €25m Non-financial performance; ESG Starting the financial year 2024, Sif has started reporting in line with CSRD. In the first three quarters Sif has participated in projects resulting in 934 MW renewable energy capacity. With the increase in manufacturing capacity and Sif’s ability to service larger capacity wind farms, Sif expects its participation to show an increasing trend going forward. Trading Update 7 November 2025 Roermond, the Netherlands Sif’s safety statistics have improved in Q3 2025 in a challenging environment of enlarging products. The new production facilities will better balance product-size and manufacturing-lay out and techniques. Outlook The order book at the end of September amounts to 586 Kton. Tendering has seen a slowdown in activity during the quarter, and the market remains hesitant with offshore wind park project awards being postponed or even cancelled. We maintain the guidance provided at the release of our Q2 numbers. 2026 Financial Calendar March 13, 2026 Release of full year 2025 results and 2025 Annual Report May 8, 2026 Release of Q1 2026 Trading update May 8, 2026 Annual General Meeting of Shareholders July 30, 2026 Release of 2026 interim results November 6, 2026 Release of Q3 2026 Trading update Contact Fons van Lith, Investor Relations Telephone: +31 (0)651314952 Email: f.vanlith@sif-group.com Trading Update 7 November 2025 Roermond, the Netherlands Definition and Explanation of use of non-IFRS financial measures Contribution (per ton or month) Total revenue from contracts with customers minus raw materials, subcontracted work and other external charges and logistic and other project-related expenses. Contribution is an important KPI since it excludes pass-through expenses. Together with production in Kton and EBITDA it indicates the quality of Sif’s performance in any reporting period. For the per ton or month measures contribution is adjusted for contribution related to Marshalling and Logistics services, Engineering and fees for projects with no production volume. EBITDA Adjusted EBITDA Earnings before net finance costs, tax, depreciation and amortization. The company discloses EBITDA and Adjusted EBITDA as supplemental non-IFRS financial measures, as the company believes these are meaningful measures to evaluate the performance of the company’s business activities over time.

The company also believes that the presentation of EBITDA and Adjusted EBITDA provide useful information to investors on the development of the company’s business.
