The Board of Xeros Technology Group plc (the "Company") is pleased to announce a retail offer via BookBuild (the "Retail Offer") of new ordinary shares of 0.1p each ("Ordinary Shares") in the capital of the Company (the "Retail Offer Shares") at an issue price of 1.75 pence per New Ordinary Share (as defined below) (the "Issue Price").

In addition to the Retail Offer, the Company is also conducting a Placing and Subscriptions of new ordinary shares (the "Placing Shares", the "Subscription Shares" and together with the Retail Offer Shares, the "New Ordinary Shares") at the Issue Price (the "Placing", the "Subscription" and together with the Retail Offer, the "Fundraising"). A separate announcement has been made regarding the Placing and Subscriptions and their terms. For the avoidance of doubt, the Retail Offer is not part of the Placing and Subscriptions. Full details of the Fundraising, including the background to and reasons for the Placing and Subscriptions and the Retail Offer is included in the separate announcement released by the Company yesterday.

The Issue Price represents a discount of approximately 22.22 per cent. to the closing share price of 2.25 pence per Existing Ordinary Share on 5 November 2025.

The Retail Offer is conditional on the passing of the Resolutions and Admission. Admission of the Retail Offer Shares is expected to take place at 8:00 a.m. on 1 December 2025. Completion of the Retail Offer is conditional, inter alia, upon the Resolutions being duly passed by Shareholders at the General Meeting to be held at the offices of Squire Patton Boggs (UK) LLP at 60 London Wall London EC2M 5TP at 10:00 a.m. on 28 November 2025.

The net proceeds of the Fundraising will be used to:

• strengthen the Company's balance sheet, enabling execution of current contracts, pursuit of global opportunities and to provide reassurance to contract counterparties;
• provide working capital as the Company advances commercialisation of its core technologies;
• provide contingency against timing of royalty income and operational cash flow break-even; and
• as appropriate, scale operations and accelerate development of other markets and applications for the Company's intellectual property.
