Independent statutory auditor's report on the review of the condensed interim consolidated financial statements

To the Shareholders and the Supervisory Board of Santander Bank Polska S.A.

Introduction

We have reviewed the accompanying condensed consolidated statement of financial position of Santander Bank Polska S.A. (hereinafter called "the Parent Company") and its subsidiaries (together hereinafter called "the Group") as at 30 June 2025 and the related condensed consolidated income statement, the condensed consolidated statement of comprehensive income, the condensed consolidated statement of changes in equity and the condensed consolidated statement of cash flows for the six-month period then ended, and the related explanatory notes ("the condensed interim consolidated financial statements").

Management of the Parent Company is responsible for the preparation and presentation of these condensed interim consolidated financial statements in accordance with the International Accounting Standard 34 Interim Financial Reporting as adopted by the European Union. Our responsibility is to express a conclusion on these condensed interim consolidated financial statements based on our review.

Scope of review

We conducted our review in accordance with the National Standard on Review Engagements 2410 in the wording of the International Standard on Review Engagements 2410 Review of Interim Financial Information Performed by the Independent Auditor of the Entity as adopted by the resolution of the National Council of Certified Auditors. A review of interim financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures.

A review is substantially less in scope than an audit conducted in accordance with National Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed interim consolidated financial statements have not been prepared, in all material respects, in accordance with the International Accounting Standard 34 Interim Financial Reporting as adopted by the European Union.
