This comprises (i) 213,500,000 Placing Shares; (ii) 36,500,000 Subscription Shares and (iii) 25,516,784 Open Offer Shares. The New Ordinary Shares will rank pari passu with the Existing Ordinary Shares. Admission of the Placing Shares, Subscription Shares and Open Offer Shares will occur on 14 September 2022. Following the close of the Open Offer, the Company will issue a total of 137,758,392 Warrants to the subscribers of New Ordinary Shares and a further 1,000,000 Warrants to finnCap.

Following admission, the total number of Ordinary Shares in issue with voting rights will be 785,852,475 Ordinary Shares and Shareholders may use this figure as the denominator for the calculations by which they will determine if they are required to notify their interest in, or change to their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
