Report on Review of Interim Financial Information

To Bayer Aktiengesellschaft, Leverkusen

We have reviewed the condensed consolidated interim financial statements, which comprise the condensed consolidated income statement and the condensed consolidated statement of comprehensive income, the condensed consolidated statement of financial position, the condensed consolidated statement of cash flows, the condensed consolidated statement of changes in equity as well as selected explanatory notes to the condensed consolidated interim financial statements, and the interim group management report of Bayer Aktiengesellschaft, Leverkusen for the period from 1 January to 30 June 2026, that are part of the half-year financial information under Section 115 German Securities Trading Act (WpHG). The preparation of the condensed interim consolidated financial statements in accordance with the IFRS® Accounting Standards issued by the International Accounting Standards Board (IFRS Accounting Standards) applicable to interim financial reporting, as adopted by the EU and of the interim group management report in accordance with the requirements of the WpHG applicable to interim group management reports is the responsibility of the executive directors of the Company. Our responsibility is to issue a review report on the condensed consolidated interim financial statements and on the interim group management report based on our review.

We conducted our review of the condensed consolidated interim financial statements and of the interim group management report in compliance with the German Generally Accepted Standards for Reviews of Financial Statements promulgated by the Institut der Wirtschaftsprüfer (IDW) and in supplementary compliance with the International Standard on Review Engagements 2410 “Review of Interim Financial Information Performed by the Independent Auditor of the Entity”. Those standards require that we plan and perform the review to obtain a certain level of assurance to preclude through critical evaluation that the condensed consolidated interim financial statements have not been prepared, in material respects, in accordance with the IFRS applicable to interim financial reporting, as adopted by the EU, or that the interim group management report has not been prepared, in material respects, in accordance with the requirements of the WpHG applicable to interim group management reports. A review is limited primarily to inquiries of company personnel and to analytical procedures applied to financial data and thus provides less assurance than an audit. Since, in accordance with our engagement, we have not performed an audit, we do not express an audit opinion.

Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed consolidated interim financial statements of Bayer Aktiengesellschaft, Leverkusen, have not been prepared, in material respects, in accordance with the IFRS Accounting Standards applicable to interim financial reporting, as adopted by the EU or that the interim group management report has not been prepared, in material respects, in accordance with the requirements of the WpHG applicable to interim group management reports.
