INDEPENDENT AUDITOR'S REPORT ON REVIEW OF HALF-YEAR CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

To the Shareholders and Supervisory Board of ORLEN S.A.

Introduction

We have reviewed the accompanying half-year condensed consolidated financial statements of ORLEN S.A. Group (hereinafter: the "Group"), for which ORLEN S.A. with its registered office in Płock, ul. Chemików 7 is the Parent (hereinafter: the "Parent"), comprising: the consolidated statement of financial position prepared as at 30 June 2023, the consolidated statement of profit or loss and other comprehensive income, consolidated statement of changes in equity, consolidated statement of cash flows for the period from 1 January 2023 to 30 June 2023 and selected explanatory notes ("interim condensed consolidated financial statements").

The Management Board of the Parent is responsible for the preparation and presentation of these half-year condensed consolidated financial statements in accordance with International Accounting Standard 34 "Interim Financial Reporting" announced in the form of Commission Regulations.

Our responsibility isto express a conclusion on these half-year condensed consolidated financialstatements 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" adopted by the National Council of Statutory Auditors.

A review of half-year condensed consolidated 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 in line with the wording of International Standards on Auditing adopted by the National Council of Statutory Auditors 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 on these half-year condensed consolidated financial statements.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying half-year condensed consolidated financial statements are not prepared, in all material respects, in accordance with International Accounting Standard 34 "Interim Financial Reporting" announced in the form of Commission Regulations.
