The Placing is conditional, inter alia, upon the Admission becoming effective. Application has been made to the London Stock Exchange for the 16,365,000 New Ordinary Shares to be issued pursuant to the Placing to be admitted to trading on AIM and, subject to the Placing Agreement not having been terminated in accordance with its terms, it is expected that Admission will become effective and trading will commence at 8.00 a.m. on 16 March 2022.

Total Voting Rights

On Admission, the total number of Ordinary Shares in issue will be 180,676,939 and the total number of voting rights will therefore be 180,676,939. This figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
