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

Result of Proposed Placing and

Completed Sale of Sale Shares

Further to the announcement made on 3 August 2021 by the Company in connection with the proposed placing to raise gross proceeds of up to £2.84 million (the "Placing Announcement"), CAP-XX, a world leader in the design and manufacture of supercapacitors and energy management systems, announces that it has conditionally raised total gross proceeds of £2.84 million before expenses by way of a placing of New Shares at an Issue Price of 5.5 pence per New Share following the closing of the Bookbuild, which was significantly oversubscribed. The Issue Price represents a 11.29 per cent. discount to the closing mid-market price per Ordinary Share on 2 August 2021.

A total of 51,629,100 New Shares were placed with institutional investors. The placing of New Shares is conditional upon, among other things, Admission becoming effective. The Bookbuild was managed by Cenkos Securities plc, the Company's joint broker.

In addition, the Company is pleased to announce the successful sale of 10,498,700 Sale Shares, which are currently held by the Selling Shareholder with responsibility for managing the Company's employee share plan, on behalf of certain of the Company's directors and employees following the exercise of options by those individuals as announced on 10 December 2020. The Sale Shares are sold as a single consolidated holding rather than individuals providing separate instructions to a broker.

Details of the holdings of Company's directors and persons discharging managerial responsibilities (PDMRs) following the sale of the Sale Shares and Admission can be found in the table below.

Application has been made for the 51,629,100 New Shares to be admitted to trading on AIM, and it is expected that Admission will occur at 8.00 a.m. on or around 10 August 2021. Following Admission of the New Shares, the Company's issued ordinary share capital will comprise 508,433,183 Ordinary Shares of no par value, none of which are held in treasury.

Following Admission of the New Shares, the total number of Ordinary Shares with voting rights in the Company will be 508,433,183, which 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 Financial Conduct Authority's Disclosure Guidance and Transparency Rules.

Other than where defined, capitalised terms used in this announcement have the meanings given to them in the Placing Announcement.

Related Party Transaction

Canaccord Genuity Group Inc, a substantial shareholder of the Company, has agreed to acquire up to 20,647,483 New Shares at the Issue Price in the Placing. Following this participation, Canaccord Genuity Group Inc will have a beneficial interest in 75,347,483 Ordinary Shares in the Company, representing approximately 14.82 per cent. of the enlarged issued share capital of the Company on Admission.

The participation of Canaccord Genuity Group Inc for up to 20,647,483 New Shares in the Placing is deemed to be a related party transaction under the AIM Rules for Companies. The directors of the Company consider, having consulted with the Company's nominated adviser, Allenby Capital Limited, that the terms of Canaccord Genuity Group Inc's purchase of New Shares in the Placing are fair and reasonable insofar as the Shareholders are concerned.
