Total voting rights

CAP-XX, a world leader in the design and manufacture of supercapacitors and energy management systems, announces that it has received a notice to exercise warrants ("Warrants") over 85,000,000 new ordinary shares of no par value each in the Company (the "New Ordinary Shares") at an exercise price of 0.15 pence per Warrant, raising approximately £127,500 for the Company.

Admission and Total Voting Rights

Application will be made to the London Stock Exchange for the New Ordinary Shares to be admitted to trading on AIM ("Admission"). It is expected that Admission will become effective and that dealings in the New Ordinary Shares on AIM will commence on or around 6 August 2024.

Following Admission, the Company's enlarged issued ordinary share capital will comprise 2,993,226,437 ordinary shares of no par value, with one voting right each. The Company does not hold any ordinary shares in treasury. Therefore, the total number of ordinary shares and voting rights in the Company is 2,993,226,437. This figure may be used by shareholders in the Company 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.
