Funding Update

London, 30 May 2025 - Celadon Pharmaceuticals Plc (AIM: CEL), a UK-based pharmaceutical company focused on the development, production and sale of breakthrough cannabis-based medicines, provides an update on its financial position. The Company announced on 30 April 2025 that it had sufficient funding to trade into May 2025 as it sought to secure additional funding for the business.

The Company has been unable to obtain funding under its existing credit facility and the directors no longer expect to receive funds under this facility in the near future. The Company has however, over recent weeks, been engaged with a new finance provider who has concluded due diligence and who has indicated he is in the process of making funds available.

As of today the Company has limited working capital and its ability to continue to trade is fully dependent upon receiving funds from the new finance provider, continued creditor and stakeholder support. In the event the Company cannot secure funds over the coming days, the directors will have to protect the interests of all stakeholders and the Company will be placed into administration.

In the event funding for the Group is secured, the Company remains committed to proceeding with a cancellation of trading of the Company's ordinary shares on AIM.

A further announcement will be made as and when appropriate.
