Update on Timing of Results and Equity Issue

The Company today announces an update regarding the timing of the publication of its audited financial results for the year ended 31 December 2022 ("FY22") and its upcoming issue of $30m of new ordinary shares (the "Equity Issue").

FY22 Audited Accounts

The audit of the Group's financial results for FY22 is well advanced, however, the auditor, BDO LLP, has requested more time to complete their procedures.

It is now expected that the audited financial results for FY22 will be released on 4 July 2023, a change to the previously planned date of 30 June 2023.The Board does not expect the audit to result in any material changes to the financial results for FY22 from recent disclosures. The Company envisages that the audited FY22 Annual Report & Accounts will be prepared on a going concern basis.

Equity Issue

The Company is in advanced stages of preparing the Equity Issue. Given the change to the audit timetable, the Company now expects to launch the Equity Issue on Monday, 3 July 2023.

Accordingly, the Company will seek the suspension on the shares to be lifted on or around 7 July 2023 following publication of the FY22 Annual Report & Accounts and completion of the Equity Issue.
