Retail Offer via BookBuild

The Board of Gelion is pleased to announce a retail offer via BookBuild (the "Retail Offer") of up to 2,126,554 new ordinary shares ("Ordinary Shares") of 0.1p each in the capital of the Company (the "Retail Offer Shares") at an issue price of 9 pence per New Ordinary Share (as defined below) (the "Issue Price") to raise total gross proceeds of £191,389.86.

In addition to the Retail Offer, the Company is also conducting a placing and subscription of new ordinary shares (the "Placing and Subscription Shares", together with the Retail Offer Shares, the "New Ordinary Shares") at the Issue Price (the "Placing and Subscription" and together with the Retail Offer, the "Fundraising"). A separate announcement earlier today regarding the Placing and its terms and provides updates in relation to the Company's recent activities and sets out the reasons for the Placing and Subscription. The net proceeds of the Fundraising will be used to advance the Company's strategic partnership with the Max Planck Institute, business development workstreams, establishing corporate collaboration, expansion of the Company's Integration Solutions business and for general working capital purposes.

The Issue Price represents a discount of approximately 12.20 per cent to the closing share price of 10.25 pence per existing Ordinary Share on 16 April 2025.

The Retail Offer is conditional, inter alia, upon approval of resolutions to be proposed to Shareholders at a General Meeting to be held on 6 May 2025 and on the Retail Offer Shares being admitted to trading on the AIM market operated by the London Stock Exchange ("Admission"). Admission of the Retail Offer Shares is expected to take place at 8 May 2025. Completion of the Retail Offer is conditional, inter alia, upon the completion of the Placing and Subscription. For the avoidance of doubt, the Retail Offer is not part of the Placing and Subscription.
