The detailed reasons for and background to the Resolutions are set out in the Circular, which will be posted on the Company's website later today and posted to shareholders early next week.

Capitalised terms used in this announcement have the meaning given in the Placing Announcement unless the context requires otherwise or as otherwise defined herein.

The Form of Proxy for use in connection with the General Meeting should be completed and returned in accordance with the instructions thereon so as to be received by the Company's registrars, Computershare Investor Services (Ireland) Limited, 3100 Lake Drive, Citywest Business Campus, Dublin 24, D24 AK82, Ireland by no later than 10.00 a.m. on 27 December 2023.

Completion and return of a Form of Proxy will not preclude Shareholders from attending and voting in person at the General Meeting should they so wish.

In the Placing Announcement, it was reported that LC Capital would be issued with 3,278,000 LC Warrants over unissued New Ordinary Shares in connection with the Conditional Placing. This should have noted that LC Capital would be issued with 4,768,000 LC Warrants over unissued New Ordinary Shares in connection with the Conditional Placing. The aggregate number of warrants LC will hold following the issue of the LC Warrants will be 41,529,826, as reported in the Placing Announcement.

Recommendation

The Directors consider the passing of the Resolutions to be in the best interests of the Company and its Shareholders as a whole. The Directors wish to raise additional working capital by completing the Conditional Placing and in the future an equity fundraising may be required at short notice to raise further capital to allow the Company to continue as a going concern in the event of such additional working capital being available on terms acceptable to the Directors. Accordingly, the Directors unanimously recommend that all Shareholders vote in favour of the Resolutions, as they intend to do, or procure to be done, in respect of their own beneficial shareholdings, being at the Latest Practicable Date, in aggregate, 10,229,279 Ordinary Shares, representing approximately 0.86 per cent. of the existing issued Ordinary Share capital. In addition, LC Capital has indicated that it intends to vote in favour of the Resolutions in respect of its holdings of 171,241,938 Ordinary Shares representing 14.35% of the existing issued Ordinary Share capital.
