("Gelion" or the "Company")

Result of Oversubscribed WRAP Retail Offer

Gelion plc (AIM: GELN) the global energy storage innovator, is pleased to confirm, further to its announcements made on 16 October 2025 and 20 October 2025, the result of its Fundraise. The WRAP Retail Offer was oversubscribed and closed early. Following scale back, the Company raised gross proceeds of £0.5 million through the issue of 2,500,000 new Ordinary Shares at the Issue Price pursuant to the WRAP Retail Offer.

In total, the Placing, Subscription and WRAP Retail Offer have raised gross proceeds of approximately £10.5 million for the Company, via the issue of 37,972,000 Placing Shares, 12,028,000 Subscription Shares and 2,500,000 WRAP Retail Offer Shares at 20 pence per share.

The Placing, Subscription and WRAP Retail Offer are each conditional, inter alia, upon Shareholders approving the Resolutions at the General Meeting which is expected to be held on 5 November 2025. The Circular, which contains the Notice of General Meeting in respect of the Fundraising, was posted to Shareholders on 20 October 2025 and is available on the Company's website at www.gelion.com.

Admission and Total Voting Rights

Applications have been made for the Placing Shares, Subscription Shares and the WRAP Retail Offer Shares to be admitted to trading on AIM ("Admission"). Admission is expected to become effective at 8.00 a.m. on or around 7 November 2025.

Upon Admission, the Company's issued ordinary share capital will consist of 229,351,783 Ordinary Shares with one voting right each. The Company does not hold any Ordinary Shares in treasury. Therefore, from Admission the total number of Ordinary Shares and voting rights in the Company will be 229,351,783. With effect from Admission, this figure may be used by Shareholders in the Company as the denominator for the calculations 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.

The new Ordinary Shares to be issued pursuant to the WRAP Retail Offer will be issued free of all liens, charges and encumbrances and will, on Admission, rank pari passu in all respects with the new Ordinary Shares to be issued pursuant to the Placing, the Subscription and the Company's existing Ordinary Shares.

Terms used but not defined in this announcement have the same meanings given to them in the Company's announcements released at 4.43 p.m. and 5.30 p.m. 16 October 2025.
