Assurance Statement

To the members of the Executive Board and the Supervisory Board of OMV Aktiengesellschaft, Vienna

Independent Assurance Report on the Non-financial Reporting according to §§ 243b and 267a UGB

We have performed an independent limited assurance engagement on the combined consolidated non-financial report according to §§ 243b and 267a UGB ("NFI report") for the financial year 2023, which has been published as Sustainability Report 2023 of

OMV Aktiengesellschaft, Vienna (referred to as "the Company").

Conclusion

Based on the procedures performed and the evidence we have obtained, nothing has come to our attention that causes us to believe that the NFI report of the Company is not in accordance with the legal requirements of the Austrian Sustainability and Diversity Improvement Act (§§ 243b and 267a UGB), the provisions of Article 8 of the Regulation (EU) 2020/852 as amended and the supplementing delegated Regulation (EU) 2021/2178 (hereafter "EU Taxonomy Regulation") and the sustainability reporting guidelines of the Global Reporting Initiative (“GRI Standards”) in its current version (option "in accordance with") in all material respects.

Management’s Responsibility

The Company’s management is responsible for the proper preparation of the NFI report in accordance with the reporting criteria. The Company applies the legal requirements of the Austrian Sustainability and Diversity Improvement Act (§§ 243b and 267a UGB) and the GRI Standards in its current version (option "in accordance with") as reporting criteria. In addition, the company prepares disclosures in accordance with the EU Taxonomy Regulation, which are published as part of sustainability reporting.

The Company’s management is responsible for the selection and application of appropriate methods for non-financial reporting (especially the selection of significant matters) as well as the use of appropriate assumptions and estimates for individual non-financial disclosures, given the circumstances. Furthermore, their responsibilities include the design, implementation and maintenance of systems, processes and internal controls that are relevant for the preparation of the sustainability report in a way that is free of material misstatements – whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to state whether, based on our procedures performed and the evidence we have obtained, anything has come to our attention that causes us to believe that the Company’s NFI report is not in accordance with the legal requirements of the Austrian Sustainability and Diversity Improvement Act (§§ 243b and 267a UGB), the legal requirements of the EU Taxonomy Regulation and the GRI Standards in its current version (option "in accordance with") in all material respects.

Our engagement was conducted in conformity with Austrian Standards for Independent Assurance Engagements (KFS/PG 13) and in accordance with International Standard on Assurance Engagements (ISAE 3000) applicable to such engagements. These standards require us to comply with our professional requirements including independence requirements, and to plan and perform the engagement to enable us to express a conclusion with limited assurance, taking into account materiality.

An independent assurance engagement with the purpose of expressing a conclusion with limited assurance ("limited assurance engagement") is substantially less in scope than an independent assurance engagement with the purpose of expressing a conclusion with reasonable assurance ("reasonable assurance engagement"), thus providing reduced assurance. Despite diligent engagement planning and execution, it cannot be ruled out that material misstatements, illegal acts or irregularities within the non-financial report will remain undetected.

The procedures selected depend on the auditor’s judgment and included the following procedures in particular:

  • Inquiries of personnel at the group level, who are responsible for the materiality analysis, in order to gain an understanding of the processes for determining material sustainability topics and respective reporting threshholds of the Company;
  • A risk assessment, including a media analysis, on relevant information on the Company’s sustainability performance in the reporting period;
  • Evaluation of the design and implementation of the systems and processes for the collection, processing and monitoring of disclosures on environmental, social and employee-related matters, respect for human rights, anti-corruption as well as bribery and also includes the consolidation of data;
  • Inquiries of personnel at the group level, who are responsible for providing, consolidating and implementing internal control procedures relating to the disclosure of concepts, risks, due diligence processes, results and performance indicators;
  • Inspection of selected internal and external documents, in order to determine whether qualitative and quantitative information is supported by sufficient evidence and presented in an accurate and balanced manner;
  • Assessment of the processes for local data collection, validation and reporting, as well as the reliability of the reported data through a survey performed at sites on a sample basis;
  • Analytical evaluation of the data and trend of quantitative disclosures regarding the GRI Standards listed in the GRI-Index, submitted by all locations for consolidation at the group level;
  • Evaluation of the consistency of the Austrian Sustainability and Diversity Improvement Act (§§ 243b and 267a UGB), the EU Taxonomy Regulation and the GRI Standards in its current version (option "in accordance with") to disclosures and indicators of the NFI report, which apply to the Company;
  • Evaluation of the overall presentation of the disclosures by critically reading the NFI report.

The procedures that we performed do not constitute an audit or a review. Our engagement did not focus on revealing and clarifying of illegal acts (such as fraud), nor did it focus on assessing the efficiency of management. Furthermore, it is not part of our engagement to audit future-related disclosures, prior year figures, statements from external sources of information, expert opinions or references to more extensive external reporting formats of the Company.
