Our responsibility is to express a conclusion on these interim condensed consolidated financial statements based on our review.

Scope of review

We conducted our review in accordance with National Standard on Review Engagements 2410 as per 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 interim 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 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 interim condensed consolidated financial statements.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim condensed consolidated financial statements are not prepared, in all material respects, in accordance with the requirements of the International Accounting Standard 34 Interim Financial Reporting published in the form of regulations of the European Commission.

Acting on behalf of Forvis Mazars Audyt Sp. z o.o. with its registered office in Warsaw, ul. Piękna 18, registered in the list of audit firms under number 186, on behalf of which the key statutory auditor reviewed the interim condensed consolidated financial statements.
