Based on our procedures performed and the assurance information obtained, nothing has come to our attention that causes us to believe that the selected information is not prepared, in all material respects, in accordance with the applicable criteria as included in the section ‘Criteria’.

Basis for our conclusion

We have performed our limited assurance engagement on the selected information in accordance with Dutch law, including Dutch Standard 3000A ’Assurance-opdrachten anders dan opdrachten tot controle of beoordeling van historische financiële informatie (attest-opdrachten)’ (Assurance engagements other than audits or reviews of historical financial information (attestation engagements)). Our responsibilities in this regard are further described in the section ‘Our responsibilities for the assurance engagement on the selected information’ of our report.

We are independent of Van Oord N.V. in accordance with the “Verordening inzake de onafhankelijkheid van accountants bij assurance-opdrachten” (ViO, Code of Ethics for Professional Accountants, a regulation with respect to independence). This includes that we do not perform any activities that could result in a conflict of interest with our independent assurance engagement. Furthermore, we have complied with the “Verordening gedrags- en beroepsregels accountants” (VGBA, Dutch Code of Ethics for Professional Accountants).

We believe that the assurance evidence we have obtained is sufficient and appropriate to provide a basis for our conclusion.

Criteria

The criteria applied for the preparation of the selected information are the criteria developed by Van Oord N.V. and are disclosed in section “About this report” on page 87 of the annual report.

The comparability of selected information between entities and over time may be affected by the absence of a uniform practice on which to draw, to evaluate and measure this information. This allows for the application of different, but acceptable, measurement techniques.

Consequently, the selected information needs to be read and understood together with the criteria applied.

Limitations to the scope of our assurance engagement

Our assurance engagement is restricted to the selected information. We have not performed assurance procedures on any other information as included in the annual report in light of this engagement.

The selected information includes prospective information such as ambitions, strategy, plans, expectations and estimates. Prospective information relates to events and actions that have not yet occurred and may never occur. We do not provide assurance on the assumptions and achievability of this prospective information.

In the selected indicators, the calculations to determine Scope 3 Upstream Greenhouse Gas Emissions (Tonnes CO₂e) (hereinafter: the impact data) are mostly based on assumptions and sources from third parties. The assumptions and sources used are disclosed in chapter Energy and emissions performance, section Basis of reporting, of the annual report. We have assessed that these assumptions and external sources are plausible and appropriate, but we have not performed procedures on the content of these assumptions and external sources.

The references to external sources or websites are not part of our assurance engagement on the selected information. We therefore do not provide assurance on this information.

Our conclusion is not modified in respect of these matters.

Responsibilities of the management board and the supervisory board for the selected information

The management board is responsible for the preparation of the selected information in accordance with the criteria as included in the section “Criteria”. The management board is also responsible for selecting and applying the criteria and for determining that these criteria are suitable for the legitimate information needs of the intended users, considering applicable law and regulations related to reporting. The choices made by the management board regarding the scope of the selected information and the reporting policy are summarized in section “About this report” on page 87 of the annual report.

Furthermore, the management board is responsible for such internal control as it determines is necessary to enable the preparation of the selected information that is free from material misstatement, whether due to fraud or error.

The supervisory board is responsible for overseeing the reporting process of the selected information of Van Oord N.V.

Our responsibilities for the assurance engagement on the selected information

Our responsibility is to plan and perform the assurance engagement in a manner that allows us to obtain sufficient and appropriate assurance evidence for our conclusion.

Our assurance engagement is aimed to obtain a limited level of assurance to determine the plausibility of the selected information. The procedures vary in nature and timing from, and are less in extent, than for a reasonable assurance engagement. The level of assurance obtained in a limited assurance engagement is therefore substantially less than the assurance that is obtained when a reasonable assurance engagement is performed.

We apply the applicable quality management requirements pursuant to the Nadere voorschriften kwaliteitsmanagement (NVKM, regulations for quality management) and the International Standard on Quality Management (ISQM) 1, and accordingly maintain a comprehensive system of quality management including documented policies and procedures regarding compliance with ethical requirements, professional standards and other relevant legal and regulatory requirements.

Our assurance engagement included amongst others:

• Performing an analysis of the external environment and obtaining an understanding of the sector, insight into relevant sustainability themes and issues and the characteristics of the company as far as relevant to the selected information

• Evaluating the appropriateness of the criteria applied, their consistent application and related disclosures on the selected information. This includes the evaluation of the reasonableness of estimates made by the management board

• Obtaining through inquiries a general understanding of the internal control environment, the reporting processes, the information systems and the entity’s risk assessment process relevant to the preparation of the selected information, without obtaining assurance information about the implementation or testing the operating effectiveness of controls

• Identifying areas of the selected information where misleading or unbalanced information or a material misstatement, whether due to fraud or error, is likely to arise. Designing and performing further assurance procedures aimed at determining the plausibility of the selected information responsive to this risk analysis.

These procedures consisted amongst others of:

• Making inquiries of management and relevant staff at corporate level responsible for the sustainability strategy, policy and results relating to the selected information

• Interviewing relevant staff responsible for providing the information for, carrying out controls on, and consolidating the data in the selected information

• Assessing the suitability and plausibility of assumptions and sources from third parties used for the calculation underlying the Scope 3 Upstream Greenhouse Gas Emissions (Tonnes CO₂e) as included in chapter Energy and emissions performance, section Basis of reporting of annual report

• Obtaining assurance evidence that the selected information reconciles with underlying records of Van Oord N.V.

• Reviewing, on a limited sample basis, relevant internal and external documentation

• Considering the data and trends

• Reading the information in the annual report that is not included in the scope of our assurance engagement to identify material inconsistencies, if any, with the selected information

• Considering whether the selected information is presented and disclosed free from material misstatement in accordance with the criteria applied.
