Following Admission, Rosebank confirms that, in accordance with the provisions of the Disclosure Guidance and Transparency Rules of the FCA ("DTR"), its issued ordinary share capital comprises 988,421,186 Ordinary Shares. The Company does not hold any Ordinary Shares in treasury. Therefore, the total number of voting rights in the Company following Admission is 988,421,186. This figure may be used by Shareholders as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the DTRs. The New Ordinary Shares rank pari passu in all respects with the Existing Ordinary Shares.
