Independent Auditor's Report

To Covestro AG, Leverkusen

Report on the audit of the compensation report

We have audited the attached compensation report of Covestro AG, Leverkusen, for the financial year from January 1 to December 31, 2022, including the related disclosures, prepared to meet the requirements of Section 162 AktG [Aktiengesetz: German Stock Corporation Act].

The compensation report contains cross-references that are not required by law and which are marked as unaudited. We have not audited the cross-references and the information to which the cross-references refer.

Responsibilities of Management and the Supervisory Board

The management and the Supervisory Board of Covestro AG are responsible for the preparation of the compensation report, including the related disclosures, in accordance with the requirements of Section 162 AktG. The management and the Supervisory Board are also responsible for such internal controls that they consider necessary for enabling the preparation of the compensation report, including the related disclosures, that is free from material misstatement, whether due to fraud (i.e. fraudulent financial reporting and misappropriation of assets) or error.

Auditor’s responsibilities

Our responsibility is to express an opinion on this compensation report, including the related disclosures, based on our audit. We conducted our audit in accordance with the German Generally Accepted Standards of Financial Statement Audits promulgated by the Institut der Wirtschaftsprüfer (Institute of Public Auditors in Germany] (IDW). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the compensation report, including the related disclosures, is free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts, including the related disclosures, in the compensation report. The procedures selected depend on the auditor’s professional judgment. This includes an assessment of the risks of material misstatement, whether due to fraud or error, in the compensation report, including the related disclosures. In assessing these risks, the auditor considers the internal control system relevant for the preparation of the compensation report, including the related disclosures. The objective is to plan and perform audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management and the Supervisory Board, as well as evaluating the overall presentation of the compensation report, including the related disclosures.

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

Opinion

In our opinion, on the basis of the knowledge obtained in the audit, the compensation report for the financial year from January 1 to December 31, 2022, including the related disclosures, complies in all material respects with the financial reporting requirements of Section 162 AktG.

Our opinion on the compensation report does not extend to the cross-references, which are marked as unaudited and not required by law, and the information to which the cross-references refer.

Other matter – formal examination of the compensation report

The substantive audit of the compensation report described in this independent auditor’s report includes the formal examination of the compensation report required by Section 162 (3) AktG, including issuing an assurance report on this examination. As we have issued an unqualified opinion on the substantive audit of the compensation report, this opinion includes the conclusion that the disclosures pursuant to Section 162 (1) and (2) AktG have been made, in all material respects, in the compensation report.

Limitation of liability

The terms governing this engagement, which we fulfilled by rendering the aforesaid services to Covestro AG, are set out in the General Engagement Terms for Wirtschaftsprüfer and Wirtschaftsprüfungsgesellschaften [German Public Auditors and Public Audit Firms] as amended on January 1, 2017. By taking note of and using the information as contained in this auditor’s report, each recipient confirms to have taken note of the terms and conditions laid down therein (including the limitation of liability of EUR 4 million for negligence under Clause 9 of the General Engagement Terms) and acknowledges their validity in relation to us.
