Ovoca Bio plc

("Ovoca" or the "Company")

Delisting from Euronext Growth Exchange

Further to the Company's press release of 7 May 2025, Ovoca confirms that the admission of Ovoca Ordinary Shares to trading on Euronext Growth was cancelled with effect from 7.00 am today, 5 June 2025 (the "Cancellation"). The Company will remain listed on the AIM Market of the London Stock Exchange, although presently share trading is suspended and has been since May 7, 2025.

As previously stated, the Cancellation was agreed to by the Board of the Company to consolidate trading of the Company's ordinary shares to the AIM Market, where the majority of the trading liquidity in the Company's ordinary shares is located. The Cancellation will also remove certain costs, complexities and duplication that comes from administering two listing regimes and will have no impact on Ovoca's Ordinary Shares which will continue to be admitted to AIM.
