Scope of Review

We conducted our review in accordance with 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 Statutory Auditors as the National Standard on Review 2410. 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 or International 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 as at 30 June 2025 are not prepared, in all material respects, in accordance with IAS 34 Interim Financial Reporting, as adopted by the European Union.
