Gelion plc

("Gelion" or the "Company")

WRAP Retail Offer for up to £500k

Gelion plc (AIM: GELN) the global energy storage innovator, is pleased to announce a retail offer via the Winterflood Retail Access Platform ("WRAP") to raise up to £500,000 (the "WRAP Retail Offer") through the issue of new ordinary shares of 0.1p each in the capital of the Company ("Ordinary Shares").  Under the WRAP Retail Offer, up to 2,500,000 new Ordinary Shares (the "WRAP Retail Offer Shares") will be made available at a price of 20 pence per share.

In addition to the WRAP Retail Offer and as announced earlier today, the Company is also proposing a placing and subscription of 50,000,000 new Ordinary Shares (together with the WRAP Retail Offer Shares, the "New Ordinary Shares") to raise approximately £10 million (before expenses) through a bookbuild process at a price of 20 pence per share (the "Issue Price"). The issue price of the WRAP Retail Offer Shares is equal to the Issue Price.

A separate announcement has been made regarding the Placing and Subscription and its terms and sets out the reasons for the Placing and Subscription and the intended use of proceeds.  The net proceeds of the WRAP Retail Offer will be utilised in the same way as the proceeds of the Placing and Subscription.

For the avoidance of doubt, the WRAP Retail Offer is not part of the Placing or the Subscription. Completion of the WRAP Retail Offer is conditional, inter alia, upon the completion of the Placing and Subscription but completion of the Placing and Subscription is not conditional on the completion of the WRAP Retail Offer.

The WRAP Retail Offer, Placing and Subscription are conditional, inter alia, on shareholder approval and the New Ordinary Shares being admitted to trading on the AIM market operated by the London Stock Exchange plc ("Admission"). It is anticipated that Admission will become effective and that dealings in the New Ordinary Shares will commence on AIM at 8.00 a.m. on 7 November 2025.

WRAP Retail Offer

The Company values its retail shareholder base and believes that it is appropriate to provide both new and existing retail shareholders in the United Kingdom the opportunity to participate in the WRAP Retail Offer.

Therefore, the Company is making the WRAP Retail Offer open to eligible investors in the United Kingdom, being new or existing shareholders of Gelion, following release of this announcement and through certain financial intermediaries.

A number of retail platforms are able to access the WRAP Retail Offer. Non-holders or existing shareholders wishing to subscribe for WRAP Retail Offer Shares should contact their broker or wealth manager who will confirm if they are participating in the Retail Offer.

Retail brokers wishing to participate in the Retail Offer on behalf of eligible retail investors, should contact [email protected].

The Retail Offer is expected to close at 4.30 p.m. on 23 October 2025. Eligible retail investors should note that financial intermediaries may have earlier closing times. The result of the Retail Offer is expected to be announced by the Company on or around 24 October 2025.

To be eligible to participate in the Retail Offer, applicants must be a customer of a participating intermediary including individuals aged 18 years or over, companies and other bodies corporate, partnerships, trusts, associations and other unincorporated organisations. 

There is a minimum subscription of £100 per investor under the Retail Offer. The terms and conditions on which investors subscribe will be provided by the relevant financial intermediaries including relevant commission or fee charges.

The Company reserves the right to amend the size of the retail offer at its discretion. The Company reserves the right to scale back any order and to reject any application for subscription under the WRAP Retail Offer without giving any reason for such rejection.

It is vital to note that once an application for WRAP Retail Offer Shares has been made and accepted via an intermediary, it cannot be withdrawn.

The WRAP Retail Offer Shares will, when issued, be credited as fully paid, and have the right to receive all dividends and other distributions declared, made or paid after their date of issue.

Investors should make their own investigations into the merits of an investment in the Company. Nothing in this announcement amounts to a recommendation to invest in the Company or amounts to investment, taxation or legal advice.

It should be noted that a subscription for Ordinary Shares and investment in the Company carries a number of risks, including the risk that investors may lose their entire investment. Investors should take independent advice from a person experienced in advising on investment in securities such as the Ordinary Shares if they are in any doubt.

An investment in the Company will place capital at risk. The value of investments, and any income, can go down as well as up, so investors could get back less than the amount invested.

Neither past performance nor any forecasts should be considered a reliable indicator of future results.

The Retail Offer is offered in the United Kingdom under the exemption from the requirement to publish a prospectus in sections 86(1)(e) and 86(4) of FSMA. As such, there is no need for publication of a prospectus pursuant to the United Kingdom version of Regulation (EU) 2017/1129 as it forms part of United Kingdom law by virtue of the European Union (Withdrawal) Act 2018 (as amended), or for approval of the same by the FCA. The Retail Offer is not being made into any jurisdiction other than the United Kingdom.
