Van Oord has reported on the state of affairs in the company and its subsidiaries in its 2025 Annual Report. The annual report is intended for all interested parties. In it, we report on the company’s performance, its strategy and value creation, governance, financial results and non-financial indicators.

This annual report has been approved by the Supervisory Board and will be adopted by the shareholders on 9 April 2026. The accompanying annual financial statements have been audited by EY Accountants B.V. Our financial statements are in accordance with the Dutch GAAP, the generally accepted accounting principles of financial reporting in the Netherlands, and the statutory regulations concerning annual financial statements, as included in the Dutch Civil Code, Part 9, Book 2.

The non-financial information contained in this report complies with our own reporting guidelines and the relevant sections of the Sustainability Reporting Guidelines (G4) by the Global Reporting Initiative (GRI). To ensure that the report is easy to read, its structure differs from the GRI Guidelines.

Limited assurance is requested for a number of selected sustainability indicators. They are:

• Carbon footprint: Greenhouse gas emissions expressed in tonnes of carbon dioxide equivalents. Concerns greenhouse gas emissions from fuel and electricity use in all equipment, flights, vehicles, offices and shipyards as well as supply chain emissions from purchased goods and services, transport and capital goods. These emissions fall under scope 1, scope 2 and upstream scope 3 emissions as defined in the Greenhouse Gas Protocol, and the totals are subject to assurance.

• Cumulative renewable energy capacity installed: Cumulative renewable energy capacity installed by all projects that Van Oord and its acquired companies contributed to since the beginning of our offshore wind activities in 2002. The capacity of the whole project is included, in MW, in the year that all of the physical units of our scope were installed. Our involvement has been substantial in these projects, ranging from transporting and installing main components all the way up to delivering turnkey projects, including engineering, procurement and construction of full renewable energy projects.

• Lost Time Injury Frequency Rate (LTIFR): Number of recordable injuries with absence (more than 24 hours) per 200,000 hours worked by workers on Van Oord’s payroll (excluding Mackley) or hired in from other companies, based on 2,693 hours per FTE; based on compulsory notifications by projects, fleet, offices and yards to the QHSE department. LTIFR includes all reported cases (with absence more than 24 hours). Mackley has its own system for registration and follow up of incidents as well as its own ISO certifications.

• Total Recordable Injury Rate (TRIR): Number of recordable injuries per 200,000 hours worked by workers on Van Oord’s payroll (excluding Mackley) or hired in from other companies, based on 2,693 hours per FTE; based on compulsory notifications by projects, fleet, offices and yards to the QHSE department.

TRIR includes all reported cases. Mackley has its own system for registration and follow up of incidents as well as its own ISO certifications.

• Spills with significant environmental impact: These are reported spills released beyond the site boundary, leading to a breach of licence conditions likely to result in prosecution and/or where external assistance is required to manage the environmental impact.

• Tenders assessed for environmental and social due diligence: The percentage and number of tenders that have undergone an environmental and social due diligence assessment are subject to assurance.

• Sustainable Supply Chain: Number of suppliers assessed by Van Oord on Environmental, Social and Corporate Governance risks. The number represents the cumulative number of suppliers scanned using external data provided by a data science company and provides insight into how companies conduct their business relating to human rights, labour standards, corruption and environmental issues.

• Energy consumption: Energy consumed in gigawatt hour. Concerns the electricity that is used on Van Oord yards, offices and vehicles, as well as the total fuel energy consumption from Van Oord marine and land-based equipment. The total fuel energy consumption and electricity consumption are subject to assurance.
