The Retail Offer

CAP-XX (AIM: CPX), the AIM quoted leader in the design and manufacture of thin, prismatic supercapacitors and energy management systems is pleased to announce a conditional retail offer of new ordinary shares in the capital of the Company ("Ordinary Shares") via RetailBook (the "Retail Offer") (the "RetailBook Offer Shares") at an issue price of 0.15 pence per new Ordinary Share (the "Issue Price"), being a discount of c. 31.8 per cent to the closing mid-price of the Company's existing Ordinary Shares on 29 July 2026. The Company is also conducting a placing of new Ordinary Shares to institutional investors by way of an accelerated bookbuilding process (the "Placing") and certain directors and non-Board members of the management team of the Company have confirmed their intention to subscribe for new Ordinary Shares (the "Subscription") as announced by the Company earlier today. Certain Directors have also agreed to the conversion of certain accrued Directors' fees (the "Director Fee Shares"). For the avoidance of doubt, the Retail Offer is not part of the Placing or the Subscription.

The Retail Offer is conditional on the approval of the shareholders of the Company at a General Meeting of the Company to be convened for 5.00 p.m. AEST on 26 August 2026 and the second tranche of new Ordinary Shares to be issued pursuant to the Placing, RetailBook Offer Shares, the new Ordinary Shares to be issued pursuant to the Subscription and the Director Fee Shares being admitted to trading on AIM ("Second Admission"). Second Admission is expected to take place at 8:00 a.m. on 3 September 2026.

The Retail Offer will not be completed without the Placing and Subscription also being completed.

The Company will use the net proceeds to fund the upgrade and capacity expansion of certain production lines.

Reason for the Retail Offer

The Retail Offer is open to eligible investors resident and physically located in the United Kingdom following release of this announcement. The Retail Offer is expected to close at 5.00 p.m. on 3 August 2026 and may close earlier at the discretion of the Company or if it is oversubscribed.
