CAP-XX Limited

("CAP-XX" or the "Company")

Oversubscribed Result of Retail Offer

Notice of General Meeting and posting of Circular

Total Voting Rights

CAP-XX (AIM: CPX), a world leader in the design and manufacture of thin, prismatic supercapacitors and energy management systems, announced on 30 July 2026 the launch of a Fundraising comprising a Placing and Subscription in conjunction with a Retail Offer.

The Company is pleased to announce that the Retail Offer, which was oversubscribed, successfully completed and closed at 5.00 p.m. on 3 August 2026 and that CAP-XX has conditionally raised gross proceeds of £0.1 million in the Retail Offer through the issue of 66,666,666 new Ordinary Shares at the Issue Price of 0.15 pence per share. Following the close of the Retail Offer, the Company has therefore conditionally raised aggregate gross proceeds of approximately £2.3 million at the Issue Price via the Fundraising.

First Admission took place at 8.00 a.m. on 3 August 2026 when 869,599,016 New Ordinary Shares were admitted to trading on AIM. The Company will therefore be required to issue and allot 663,733,350 Second Fundraising Shares to satisfy the balance of the Fundraising, which is conditional upon (amongst other things) the Resolution being duly passed without amendment at the General Meeting and Second Admission becoming effective at 8.00 a.m. on 3 September 2026 (or such later date as the Company and Allenby Capital may agree, but not later than 8.00 a.m. on 30 September 2026).

Notice of General Meeting and posting of Circular

The Circular, which contains the Notice of General Meeting in respect of the Fundraise, is expected to be posted to Shareholders today 4 August 2026 and will also be available on the Company's website www.cap-xx.com.

The General Meeting will be held virtually at 5.00 p.m. AEST, 8.00 a.m. BST on 26 August 2026.

The Second Admission is conditional, inter alia, on the passing of the Resolution by Shareholders at the General Meeting.

Should the Resolution to approve the issue of the Second Fundraising Shares and the Director Fee Shares not be passed at the General Meeting, the Second Admission will not proceed.

Admission and Total Voting Rights

Application will be made to the London Stock Exchange for the (in aggregate) 663,733,350 Second Fundraising Shares, as well as the 93,333,313 Director Fee Shares, to be admitted to trading on AIM. Second Admission is expected to take place and dealings in those New Ordinary Shares are expected to commence at 8.00 a.m. on 3 September 2026, at which time it is also expected that those New Ordinary Shares will be enabled for settlement in CREST. The New Ordinary Shares will rank pari passu with the existing Ordinary Shares.

Immediately following Second Admission, the issued share capital of the Company is expected to comprise 7,423,992,457 Ordinary Shares. Each Ordinary Share has one voting right and no Ordinary Shares are held in treasury. From Second Admission, 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 FCA's Disclosure Guidance and Transparency Rules.

Capitalised terms used in this announcement shall, unless defined in this announcement or unless the context provides otherwise, have the meanings given to such terms in the Company's announcement of 30 July 2026 at 4.38 p.m. (the "Launch Announcement").
