Independent assurance practitioner's report¹

To the METRO AG, Düsseldorf

We have performed a limited assurance engagement on the combined non-financial statement of the METRO AG, Düsseldorf, and the METRO Group (hereinafter the "Company"), for the period from 1 October 2022 to 30 September 2023 included in the combined management report.

As disclosed in the section "global labour and social standards in the supply chain", certifications on manufacturing facilities of suppliers were conducted by external certification firms mandated by METRO AG to ensure compliance with the environmental, social and health standards of the amfori Business Social Compliance Initiative (BSCI) or equivalent standards. The appropriateness and accuracy of the conclusions from the audit/certification work performed was not part of our assurance procedures.

Responsibilities of Management

Management of the METRO AG is responsible for the preparation of the combined non-financial statement in accordance with §§ 289c bis 289e HGB und § 315c in conjunction with §§ 289c to 289e HGB and with Article 8 of REGULATION (EU) 2020/852 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 18 June 2020 on establishing a framework to facilitate sustainable investment and amending Regulation (EU) 2019/2088 (hereinafter the "EU Taxonomy Regulation") and the Delegated Acts adopted thereunder, as well as for making their own interpretation of the wording and terms contained in the EU Taxonomy Regulation and the delegated acts adopted thereunder as set out in section "EU Taxonomy" of the combined non-financial statement.

This responsibility includes the selection and application of appropriate non-financial reporting methods and making assumptions and estimates about individual non-financial disclosures that are reasonable in the circumstances. Furthermore, management is responsible for such internal control as they consider necessary to enable the preparation of a combined non-financial statement that is free from material misstatement, whether due to fraud or error.

The EU Taxonomy Regulation and the Delegated Acts issued thereunder contain wording and terms that are still subject to considerable interpretation uncertainties and for which clarifications have not yet been published in every case. Therefore, management has disclosed their interpretation of the EU Taxonomy Regulation and the Delegated Acts adopted thereunder in section "EU Taxonomy" of the combined non-financial statement. They are responsible for the defensibility of this interpretation. Due to the immanent risk that indeterminate legal terms may be interpreted differently, the legal conformity of the interpretation is subject to uncertainties.

Independence and Quality Assurance of the Assurance Practitioner’s firm

We have complied with the independence and quality assurance requirements set out in the national legal provisions and professional pronouncements, in particular the Professional Code for German Public Auditors and Chartered Accountants (in Germany) and the quality assurance standard of the German Institute of Public Auditors (Institut der Wirtschaftsprüfer, IDW) regarding quality assurance requirements in audit practice (IDW QS 1).

Responsibility of the Assurance Practitioner

Our responsibility is to express a conclusion with limited assurance on the combined non-financial statement based on our assurance engagement.

We conducted our assurance engagement in accordance with the International Standard on Assurance Engagements (ISAE) 3000 (Revised): "Assurance Engagements other than Audits or Reviews of Historical Financial Information", issued by IAASB. This standard requires that we plan and perform the assurance engagement to obtain limited assurance about whether any matters have come to our attention that cause us to believe that the combined non-financial statement of the Company are not prepared, in all material respects, in accordance with §§ 289c bis 289e HGB und § 315c in conjunction with §§289c to 289e HGB and with the EU Taxonomy Regulation and the Delegated Acts issued thereunder as well as the interpretation by management disclosed in section "EU Taxonomy" of the combined non-financial statement.

In a limited assurance engagement, the procedures performed are less extensive than in a reasonable assurance engagement, and accordingly, a substantially lower level of assurance is obtained. The selection of the assurance procedures is subject to the professional judgment of the assurance practitioner.

In the course of our assurance engagement we have, among other things, performed the following assurance procedures and other activities:

• Inquiries of group-level personnel who are responsible for the materiality analysis in order to understand the processes for determining material topics and respective reporting boundaries for METRO AG
• A risk analysis, including media research, to identify relevant information on METRO AG’s sustainability performance in the reporting period
• Evaluation of the design and the implementation of systems and processes for the collection, processing and monitoring of disclosures, including data consolidation, on environmental, employee and social matters, respect for human rights, and combating corruption and bribery
• Inquiries of group-level personnel who are responsible for determining disclosures on concepts, due diligence processes, results and risks, performing internal control functions and consolidating disclosures
• Inspection of selected internal and external documents
• Analytical procedures for the evaluation of data and of the trends of quantitative disclosures as reported at group level by all sites
• Evaluation of local data collection, validation and reporting processes as well as the reliability of reported data via a sampling survey at METRO Deutschland GmbH and METRO FRANCE S.A.S via videoconference
• Inquiries of responsible employees at Group level to obtain an understanding of the approach to identify relevant economic activities in accordance with EU Taxonomy
• Evaluation of the design and the implementation of systems and processes for the collection, processing and monitoring of disclosures on turnover, capital expenditures and operating expenditures for the taxonomy-relevant economic activities for the environmental objectives of climate change mitigation and adaptation
• Assessment of data collection, validation and reporting processes and reliability of reported data for the taxonomy-aligned economic activities in relation to the assurance on the Technical Screening Criteria (substantial contribution for the environmental objective, DNSH criteria) and minimum safeguards
• Assessment of the overall presentation of the disclosures

In determining the disclosures in accordance with Article 8 of the EU Taxonomy Regulation, management is required to interpret undefined legal terms. Due to the immanent risk that undefined legal terms may be interpreted differently, the legal conformity of their interpretation and, accordingly, our assurance engagement thereon are subject to uncertainties.

Assurance Opinion

Based on the assurance procedures performed and the evidence obtained, nothing has come to our attention that causes us to believe that the combined non-financial statement of METRO AG, Düsseldorf, for the period from 1 October 2022 to 30 September 2023 has not been prepared, in all material respects, in accordance with §§ 289c bis 289e HGB und § 315c in conjunction with §§ 289c to 289e HGB and the EU Taxonomy Regulation and the Delegated Acts issued thereunder as well as the interpretation by management as disclosed in section "EU Taxonomy" of the combined non-financial statement.

We do not express an opinion on the conclusions of the external certification firms mentioned in the combined non-financial statement.
