Result of Retail Offer

and

Total Voting Rights

CAP-XX Limited (AIM: CPX), a global leader in prismatic, high-power supercapacitors, is pleased to confirm, further to the announcement made on 3 May 2023, the completion of its Retail Offer at the Issue Price of 1.3 pence per share. The Company announces that it has raised gross proceeds of approximately £0.18 million pursuant to the Retail Offer, alongside the previously announced Placing and Subscription. Accordingly, the Company will issue a total of 13,471,433 Retail Offer Shares at the Issue Price pursuant to the Retail Offer.

In total, the Placing, Subscription and the Retail Offer have raised gross proceeds of approximately £2.68 million for the Company. Consequently, a total of 205,779,124 New Ordinary Shares will be issued in connection with the Placing, Subscription and Retail Offer.

The second tranche of the Placing, the Subscription and the Retail Offer are conditional, inter alia, on the passing of the Resolution by Shareholders at the General Meeting, which will be held on 2 June 2023 at 5.00 p.m. AEST.

Should the Resolution not be passed at the General Meeting, the second tranche of the Placing, the Subscription and the Retail Offer will not proceed.

Admission and Total Voting Rights

Application will be made for the Second Placing Shares, Subscription Shares and the Retail Offer Shares to be admitted to trading on AIM ("Second Admission") and the date on which Second Admission is expected to become effective is on or around 6 June 2023.

Following Second Admission, the Company's issued ordinary share capital will consist of 716,014,958 Ordinary Shares with one voting right each. The Company does not hold any Ordinary Shares in treasury. Therefore, from Second Admission the total number of Ordinary Shares and voting rights in the Company will be 716,014,958. With effect from Second Admission, 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 Company under the FCA's Disclosure Guidance and Transparency Rules.

Terms used but not defined in this announcement have the same meaning as set out in the Company's announcement released on 3 May 2023.
