Placing to Raise £534,375

Hemogenyx Pharmaceuticals plc (LSE: HEMO), the biopharmaceutical group developing new therapies and treatments for blood diseases, is pleased to announce that it has successfully raised £534,375 (before expenses) through the allotment and issue of 22,500,000 new ordinary shares at 2.375 pence per share (the "Placing", "Placing Shares"). The Placing was oversubscribed and conducted on behalf of the Company by its corporate broker, Peterhouse Capital Limited.

The net proceeds from the Placing will be used to facilitate progression of the Company's Chimeric Antigen Receptor ("CAR") T-cells ("HEMO-CAR-T") for the treatment of acute myeloid leukaemia ("AML"). Specifically, and as outlined by the Company in its announcement of 15 November 2023, this fundraise will help the Company to accelerate the completion of work set out in the plan presented and agreed to by the FDA and to re-submit the Investigational New Drug ("IND") application for the HEMO-CAR-T product. The funds will also enable the Company, in view of recently announced successes, to provide modest additional resources to the development of its CBR platform.

An application is being made to the London Stock Exchange Main Market and admission of the Placing Shares to trading is expected on or around 4 December 2023 ("Admission"). The Placing Shares will rank pari passu with the existing ordinary shares in the Company.
