Independent registered auditor's report on the assurance engagement in relation to the assessment of the Remuneration Report

To the General Shareholders' Meeting, the Supervisory Board and the Management Board of Santander Bank Polska S.A.

Introduction

The Management Board of Santander Bank Polska S.A. (the "Bank") engaged us to conduct a reasonable assurance engagement for the verification of completeness and compliance with applicable requirements of the attached Remuneration Report for the year ended 31 December 2024 (the "Remuneration Report").

Description of the subject matter and applicable criteria

The Remuneration Report was prepared by the Supervisory Board to comply with the requirements in Art. 90g paragraph 1 of the Act of 29 July, 2005 on public offering, conditions for introducing financial instruments to an organized trading system and on public companies (the "Public Offering Act"). The applicable requirements regarding the Remuneration Report are contained in the Public Offering Act.

The requirements referred to in the preceding sentence determine the basis for preparation of the Remuneration Report (hereinafter the "Basis for Preparation") and, in our view, constitute appropriate criteria to form the reasonable assurance conclusion.

According to the requirements of Art. 90g paragraph 10 of the Public Offering Act, the Remuneration Report is subject to assessment by a registered auditor in terms of it including the information required under Art. 90g paragraph 1-5 and 8 of the Public Offering Act. This report fulfills these requirements.

By the registered auditor's assessment referred to above, we mean the assessment whether, in all material respects, the scope of information presented in the Remuneration Report is complete and has been disclosed with the level of detail required by the Public Offering Act. Additionally, our assessment includes verification that the information presented in the Remuneration Report is consistent, in all material respects, with the actual state of affairs, does not ignore significant facts and does not contain material distortions.

Responsibility of the Supervisory Board

The Supervisory Board is responsible for the preparation and completeness of the Remuneration Report. The Supervisory Board is responsible for the selection and application of the appropriate methods for preparation of financial data and non-financial information as well as for the design, implementation and maintenance of systems and processes of internal control and accounting records, that are necessary to enable preparation of a Remuneration Report that is free of material misstatements and complies with the applicable requirements.

Our responsibility

Our responsibility was to assess the completeness and compliance with the applicable requirements of the information contained in the attached Remuneration Report and to express, based on the evidence obtained, an independent conclusion from the assurance service performed, providing reasonable assurance.

We conducted our engagement in accordance with National Standard on Assurance Engagements Other than an Audit or Review 3000 (R) in the wording of the International Standard on Assurance Engagements 3000 (Revised) – "Assurance Engagements other than Audits and Reviews of Historical Financial Information" ("KSUA 3000 (R)"). This standard requires that we comply with ethical requirements, plan and perform procedures to obtain reasonable assurance whether the Remuneration Report is prepared, in all material aspects, in accordance with the applicable requirements.

Reasonable assurance is a high level of assurance, but it does not guarantee that the service performed in accordance with KSUA 3000 (R) will always detect the existing material misstatement (significant non-compliance with the requirements).

Quality management requirements and professional ethics

We apply the provisions of the National Standard on Quality Control 1 in the wording of the International Standard on Quality Management 1 "Quality Management for Firms that Perform Audits or Reviews of Financial Statements, or Other Assurance or Related Services Engagements" issued by the International Auditing and Assurance Standards Board and adopted by the resolution of the Board of the Polish Audit Oversight Agency. This standard requires us to design, implement and operate a system of quality management including policies or procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

We comply with the independence and other ethical requirements in accordance with the "Handbook of the International code of ethics for professional accountants (including International independence standards)" as adopted by resolution of the National Board of Statutory Auditors, which is founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour.

Summary of the work performed

Our planned and performed procedures were aimed at obtaining reasonable assurance whether the Remuneration Report was prepared, in all material aspects, in accordance with the applicable requirements, is complete and free from material misstatements and omissions. Our procedures included, in particular:

• analysis of the Remuneration Report and comparing the information contained therein with the applicable requirements;
• analysis of the resolutions of the General Shareholders' Meeting of the Bank regarding the remuneration policy for members of the Management Board and the Supervisory Board as well as any supplementary resolutions of the Supervisory Board and, where we deemed it appropriate, with other documents regulating the remuneration policy subject to the disclosure requirement in the Remuneration Report;
• understanding the procedures adopted by the Supervisory Board to meet requirements of the preparation of the Remuneration Report, including understanding the relevant internal control procedures to the extent necessary to assess the risk of material misstatement or the omission of significant information;

• identifying, by comparing with corporate documents, a list of persons for whom there is a requirement to include information in the Remuneration Report and verifying, through inquiries of persons responsible for preparing the report, and, where we consider it appropriate, also directly with persons subject to the requirement provide information on, whether all information covered by the criteria for the preparation of the Remuneration Report are disclosed in the Remuneration Report;
• where we consider it appropriate to assess the compliance of the Remuneration Report with applicable regulations, reconciliation of the financial data regarding remuneration presented in the Remuneration Report to the Bank's accounting books and relevant source documents;
• where we consider it appropriate to assess the completeness of the Remuneration Report with the applicable regulations, reconcile with the relevant source documents whether the nonfinancial information required for disclosure in the Remuneration is accurate and does not omit material facts.

The Remuneration Report was not subject to audit as defined in National Standards on Auditing. In the course of performing the assurance procedures, we have not conducted an audit or review of the historical financial information used in the process of preparation of the Remuneration Report and therefore we do not accept any responsibility for the issuance or update of any reports or opinions on historical financial information of the Bank.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our conclusion expressed below (assessment).

Conclusion (assessment)

In our opinion, the Remuneration Report is complete and complies, in all material aspects, with the applicable requirements contained in the Basis for Preparation.
