Assurance report of the independent auditor

To: the Annual General Meeting of Shareholders and the Supervisory Board of Koninklijke DSM N.V.

Report on the audit of the Sustainability information 2021 included in the Integrated Annual Report Our opinion

We have audited the sustainability information in the sections ‘Key data’, ’Co-CEO letter, ‘Our approach to the Sustainable Development Goals’, ‘Report by the Managing Board, consisting of the chapters Purpose, Strategy, Case studies, Stakeholders, People and Planet’, the ‘Non-financial reporting policy’, the ‘Sustainability Statements’ (excluding section ‘2. EU Taxonomy’ of the ‘Notes to the Sustainability statements’) and the ‘Sustainability tables’, as included in the Integrated Annual Report for the year 2021 (hereafter: the ‘Sustainability Information’) of Koninklijke DSM N.V. (hereafter ‘Royal DSM’), based in Heerlen, the Netherlands. An audit is aimed to obtain reasonable assurance.

In our opinion, the Sustainability Information is prepared, in all material respects, in accordance with the GRI Sustainability Reporting Standards and Royal DSM’s internally developed supplemental reporting criteria as disclosed in the section Non-financial reporting policy included in the chapter ‘Reporting policies’ of the Integrated Annual Report.

Basis for our opinion

We have conducted our audit on the Sustainability Information in accordance with Dutch law, including Dutch Standard 3810N ‘Assurance-opdrachten inzake maatschappelijke verslagen’ (Assurance engagements relating to sustainability reports), which is a specified Dutch standard that is based on the International Standard on Assurance Engagements (ISAE) 3000 ‘Assurance Engagements Other than Audits or Reviews of Historical Financial Information’. Our responsibilities in this regard are further described in the ‘Our responsibilities for the audit of the Sustainability Information’ section of our report.

We are independent of Royal DSM 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). Furthermore, we have complied with the ‘Verordening gedrags- en beroepsregels accountants’ (VGBA, Dutch Code of Ethics).

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

Reporting criteria

The Sustainability Information needs to be read and understood together with the reporting criteria. Royal DSM is solely responsible for selecting and applying these reporting criteria, taking into account applicable law and regulations related to reporting.

The reporting criteria used for the preparation of the Sustainability Information are the GRI Sustainability Reporting Standards and Royal DSM’s internally developed supplemental reporting criteria as disclosed in the section Non-financial reporting policy included in the chapter ‘Reporting policies’ of the Integrated Annual Report.

The GRI Sustainability Reporting Standards are the most widely adopted global standards for sustainability reporting and are used by Royal DSM for reporting publicly on its economic, environmental and social sustainability indicators.

Materiality

Based on our professional judgement we determined materiality levels for each relevant part of the Sustainability Information as included in the Integrated Annual Report. When evaluating our materiality levels, we have taken into account quantitative and qualitative considerations as well as the relevance of information for both stakeholders and Royal DSM.

Scope of the group audit

Royal DSM is the head of a group of components. The Sustainability Information incorporates the consolidated information of this group of components.

Our group audit procedures consisted of audit procedures at corporate and component level. Our selection of components in scope of our audit procedures is primarily based on the component’s individual contribution to the consolidated Sustainability Information. Furthermore, our selection of components considered relevant reporting risks and geographical spread.

By performing our procedures at corporate and component level, we have been able to obtain sufficient and appropriate audit evidence about Royal DSM’s reported Sustainability Information to provide an opinion about the Sustainability Information

Our key audit matter

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the Sustainability Information. We have communicated the key audit matter to the Managing Board and the Supervisory Board. The key audit matter is not a comprehensive reflection of all matters discussed.

This key audit matter was addressed in the context of our audit of the Sustainability Information as a whole and we do not provide a separate opinion on this matter.

The sustainability indicator on Royal DSM’s solutions labeled as Brighter Living Solutions was determined to be a key audit matter as the assessment is inherently subject to assumptions and management judgement, whereas the determination of other important sustainability indicators on Safety, Health and Environment and Human Resources require such judgement to a lesser extent.

Brighter Living Solutions

Description

Royal DSM reports on Brighter Living Solutions ("BLS”), which are products and services that have specific environmental or social benefits compared to mainstream reference solutions.

The indicator is defined as net sales from BLS as a percentage of total net sales of Royal DSM. BLS was significant to our audit since we identified that it serves as a material indicator for Royal DSM to report on the environmental and social impact of its solutions and because the assessment of solutions to qualify as BLS is inherently subject to assumptions and judgement

Our response

We obtained an understanding of the reporting process, the applicable definitions and reporting criteria and we have evaluated the design and implementation of relevant internal controls. We inquired Royal DSM’s staff members involved in the BLS assessment process to understand the application of these definitions and reporting criteria and we challenged the underlying evidence, such as the life cycle assessments and expert opinions for solutions classified as BLS and assessed the calculation of the BLS percentage. Finally, we assessed whether the reporting criteria, assumptions and definitions are adequately disclosed in the Integrated Annual Report and on Royal DSM’s website.

Our observation

We consider that the definitions and criteria for BLS as described in Royal DSM’s internally developed supplemental reporting criteria, as disclosed in the section Non-financial reporting policy included in the chapter ‘Reporting policies’ of the Integrated Annual Report are appropriately applied and that the assumptions are adequately explained. We also consider the disclosure on BLS as being adequate.

Limitations to the scope of our audit

The Sustainability Information includes prospective information such as ambitions, strategy, plans, expectations and estimates. Inherently the actual future results are uncertain. We do not provide any assurance on the assumptions and achievability of prospective information included in the aforementioned sections of the Integrated Annual Report.

References to external sources or websites in the Integrated Annual Report are not part of the Integrated Annual Report itself nor the Sustainability Information as audited by us. Therefore, we do not provide assurance on this information.

Our opinion is not modified in respect to these matters.

Responsibilities of the Managing Board and the Supervisory Board for the Sustainability Information

The Managing Board of Royal DSM is responsible for the preparation of the Sustainability Information in accordance with the GRI Sustainability Reporting Standards and Royal DSM’s internally developed supplemental reporting criteria as disclosed in the section Non-financial reporting policy included in the chapter ‘Reporting policies’ of the Integrated Annual Report, including the identification of stakeholders and the definition of material matters. The choices made by the Managing Board regarding the scope of the Sustainability Information and the reporting policy are summarized in the section ‘Non-financial reporting policy’ of the Integrated Annual Report.

Furthermore, the Managing Board is responsible for such internal control as it determines is necessary to enable the preparation of the Sustainability Information that is free from material misstatements, whether due to fraud or error.

The Supervisory Board is, amongst other things, responsible for overseeing Royal DSM’s sustainability reporting process.

Our responsibilities for the audit of the Sustainability Information

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

Our audit has been performed with a high, but not absolute, level of assurance, which means we may not have detected all material misstatements due to fraud or error.

Misstatements can arise from fraud or errors and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the decisions of users taken on the basis of the Sustainability Information. The materiality affects the nature, timing and extent of our audit procedures and the evaluation of the effect of identified misstatements on our opinion.

We apply the ‘Nadere Voorschriften Kwaliteitssystemen’ (Regulations for Quality management systems) and accordingly maintain a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

We have exercised professional judgement and have maintained professional skepticism throughout the audit, in accordance with the Dutch Standard 3810N, ethical requirements and independence requirements.

Our audit included among others:

• Performing an analysis of the external environment and obtaining an understanding of relevant social themes and issues, and the characteristics of Royal DSM;
• Evaluating the appropriateness of the reporting criteria used, their consistent application and related disclosures in the Sustainability Information. This includes the evaluation of the results of the stakeholders’ dialogue and the reasonableness of estimates made by management of Royal DSM;
• Obtaining an understanding of the systems and processes for collecting, reporting and consolidating the Sustainability Information, including obtaining an understanding of internal control relevant to our audit, but not for the purpose of expressing an opinion on the effectiveness of Royal DSM’s internal control;
• Evaluating the procedures performed by Royal DSM’s Corporate Operational Audit department;
• Identifying and assessing the risks if the Sustainability Information is misleading or unbalanced, or contains material misstatements, whether due to errors or fraud. Designing and performing further audit procedures responsive to those risks, and obtaining audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk that the Sustainability Information is misleading or unbalanced, or the risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from errors. Fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. These further procedures included among others:
  • Inquiry with management and relevant staff of Royal DSM at corporate and component level responsible for the sustainability strategy, policies and results;
  • Inquiry with relevant staff of Royal DSM responsible for providing the information for, carrying out internal control procedures on, and consolidating the data in the Sustainability Information;
  • Determining the nature and extent of the audit procedures at corporate and component level. For this, the nature, size and/or risk profile of these components were decisive. Based thereon we selected the components to visit. In view of restrictions on the movement of people across borders, and also within significantly affected countries, due to the Covid-19 pandemic, we considered how to make appropriate changes to the audit plan. Due to the aforementioned restrictions, travelling generally was not practicable in the current environment and we conducted our visits remotely for components where travel was not possible. The visits were aimed at, on a component level, validating source data and evaluating the design, implementation and operation of controls and validation procedures;
  • Obtaining supporting information that the Sustainability Information reconciles with underlying records of Royal DSM;
  • Evaluating relevant internal and external documentation, on a test basis, to determine the reliability of the information in the Sustainability Information; and
  • Performing an analytical review of the data and trends.
• Evaluating the consistency of the Sustainability Information with the information in the Integrated Annual Report which is not included in the scope of our audit;
• Evaluating the overall presentation, structure and content of the Sustainability Information; and
• Considering whether the Sustainability Information as a whole, including the disclosures, reflects the purpose of the reporting criteria used.

We communicate with the Supervisory Board regarding, among other matters, the planned scope and timing of the audit and significant findings, including any significant findings in internal control that we identify during our audit.
