Result of Audit Tender

Hemogenyx Pharmaceuticals plc (LSE: HEMO), is pleased to announce that following the conclusion of the formal tender process for the role of statutory auditor, it intends to re-appoint PKF Littlejohn LLP as external auditor for the financial year ending December 2025 onwards. This will coincide with the timing of the mandatory lead audit partner rotation.

The audit tender was conducted as a result of the requirement for public interest entities to undertake an audit tender at least every ten years. A thorough tender process, overseen by the Audit Committee, was undertaken and this proposed change of auditor follows a recommendation by the Audit Committee to the Board based on the outcome of the tender process.

Further details of the audit tender process and evaluation criteria will be included in the Group’s 2025 Annual Report & Accounts. The appointment will be subject to shareholder approval at the Company’s 2026 Annual General Meeting.
