For Shareholders and the Supervisory Board of CD PROJEKT S.A.

We have been engaged to assess the attached remuneration report of CD PROJEKT S.A. (Company) with its registered office in Warsaw, 74 Jagiellońska Street, for the year 2024 as regards the completeness of the information included therein, required pursuant to Article 90g sections 1-5 and 8 of the Act of 29 July 2005 on public offering, conditions governing the introduction of financial instruments to organised trading and on public companies (Public Offering Act).

Identification of the criteria and description of the subject matter of the engagement

The remuneration report was prepared by the Company's Supervisory Board in order to meet the requirements of Article 90g section 1 of the Public Offering Act. The applicable requirements for the remuneration report are set out in the Public Offering Act.

The requirements described in the preceding sentence set out the basis for the preparation of a remuneration report and, in our opinion, constitute appropriate criteria for us to make a conclusion that provides reasonable assurance.

In accordance with the requirements of Article 90g section 10 of the Public Offering Act, a remuneration report shall be assessed by a statutory auditor as regards the inclusion of information required under Article 90g section 1-5 and 8 of the Public Offering Act. This report fulfils the above requirement.

The statutory auditor's assessment which forms the basis for us to make a conclusion that provides reasonable assurance, as referred to in the preceding sentence, shall be understood as an assessment of whether the scope of information presented in the remuneration report is complete, in all material respects, and whether the information has been disclosed in sufficient detail required by the Public Offering Act.

Responsibility of the Supervisory Board Members

In accordance with the Public Offering Act, Members of the Company's Supervisory Board are responsible for preparing a remuneration report in accordance with applicable laws, in particular for the completeness of the report and for the information contained there.

The Supervisory Board's responsibility also includes the design, implementation and maintenance of an internal control system ensuring the preparation of a complete remuneration report free from material misstatements due to fraud or error.

Auditor's responsibility

Our objective was to assess the completeness of the information contained in the attached remuneration report against the criterion set out in the Identification of the criteria and description of the subject matter of the engagement section and to express, on the basis of the evidence obtained, an independent conclusion on the performed reasonable assurance engagement.

We completed the engagement in accordance with the regulations of the National Standard for Assurance Engagements other than Audits or Reviews 3000 (R) in the wording of International Standard on Assurance Engagements (ISAE) 3000 (revised) Assurance Engagements other than Audits or Reviews of Historical Financial Information, adopted by resolution of the National Chamber of Statutory Auditors, as amended (NSAE 3000 (R)).

The standard imposes on a statutory auditor an obligation to plan and perform procedures in such a manner as to obtain reasonable assurance that a remuneration report has been prepared in accordance with the specified criteria.

Reasonable assurance means a high level of assurance, but it does not guarantee that an engagement performed in accordance with NSAE 3000 (R) would always detect an existing material misstatement.

The selection of the procedures depends on the statutory auditor's judgement, including their estimation of the risks of material misstatement, whether due to fraud or error. When assessing the risk, the statutory auditor considers internal control associated with the preparation of a compete report in order to plan the relevant procedures which are to provide the auditor with sufficient and appropriate evidence. The assessment of the functioning of the internal control system was not conducted for the purpose of expressing a conclusion on the effectiveness of its operation.

Summary of work performed and limitations of our procedures

The procedures planned and performed by us included in particular:

• reading the content of the remuneration report and comparing the information contained therein with the applicable requirements,
• reading the resolutions of the Company's General Meeting concerning the remuneration policy for Members of the Management Board and the Supervisory Board, as well as the Supervisory Board's resolutions that further specify the above resolutions,
• preparation (by comparison with corporate documents) of a list of persons for whom information is required to be included in the remuneration report and determining (by enquiring the persons responsible for preparing the report and, where we deemed it appropriate, also directly the persons subject to the requirement to include information) whether all information required in the criteria has been disclosed.

Our procedures were only aimed at obtaining evidence that the information provided by the Supervisory Board in the remuneration report complies (in terms of its completeness) with the applicable requirements. Our work was not intended to assess the sufficiency of the information contained in the remuneration report in terms of the purpose of preparation of remuneration report, nor to assess the correctness and accuracy of the information contained there, in particular as regards the amounts disclosed, including the previous years' estimates, figures, dates, inclusion in the breakdown, allocation methods, compliance with the adopted remuneration policy.

The remuneration report was not audited within the meaning of the National Auditing Standards. During our assurance procedures, we did not audit or review the information used to prepare the remuneration report and, therefore, we are not responsible for issuing or updating any reports or opinions on the Company's historical financial information.

We believe that the evidence we have obtained provides sufficient and appropriate basis for us to express the following conclusion.

Ethical requirements, including independence

In performing the engagement, the statutory auditor and the audit firm complied with the requirements of independence and other ethical requirements set out in Handbook of the International Code of Ethics for Professional Accountants (including the International Independence Standards) of the International Ethics Standards Board for Accountants, adopted by the National Council of Statutory Auditors' resolution on the principles of professional ethics of statutory auditors (IESBA Code). The IESBA Code is based on fundamental principles relating to integrity, objectivity, professional competence and due diligence, confidentiality and professional conduct. We also complied with other independence and ethical requirements that apply to this assurance engagement in Poland.

Quality management requirements

The audit firm applies national quality control standards in the wording adopted by resolution of the Council of the Polish Audit Oversight Agency, which requires the audit firm 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.

Conclusion

The statutory auditor's conclusion is based on the considerations described above, therefore, the conclusion should be read in the light of these considerations.

In our opinion, the attached remuneration report contains, in all material respects, all the elements listed in Article 90g sections 1-5 and 8 of the Public Offering Act.
