Haydale Graphene Industries Plc

("Haydale", the "Company" or the "Group")

Result of Retail Offer

The Board of Haydale Graphene Industries Plc (the "Company") is pleased to announce that the Retail Offer launched on 12 December 2025 has now closed, raising in total £0.50 million through the issuance of 100,000,000 Retail Shares at a price of 0.5 pence each.

The Retail Offer was oversubscribed and therefore allocations were made to existing shareholders, applying principles of soft pre-emption. Existing Shareholders received 100 per cent. of their soft pre-emptive allowance when their order matched or exceeded their soft pre-emptive allowance. Given the level of demand, where the order was greater than the soft pre-emptive allowance shareholders received approximately 82.85 per cent. of their additional demand.

Accordingly, conditional on the passing of the Resolutions at the General Meeting, the Company has conditionally raised total gross proceeds of approximately £5.75 million in aggregate by way of the Fundraising.

Subject to, inter alia, Shareholders passing the Resolutions at the General Meeting to be held on 6 January 2026, applications will be made to the London Stock Exchange in connection with First Admission for the admission of a total of 1,150,000,000 New Ordinary Shares to trading on AIM. This will comprise (i) 1,050,000,000 Placing and Subscription Shares; and (ii) 100,000,000 Retail Shares. Applications will also be made to the London Stock Exchange in connection with Second Admission for the admission of a total of 1,860,465,116 First Tranche Consideration Shares and 23,404,142 SMCC CLN Shares to trading on AIM. The New Ordinary Shares, when issued, will rank pari passu with the Existing Ordinary Shares then in issue.

Subject to, and conditional on, the Resolutions being passed at the General Meeting, First Admission is expected to occur on 7 January 2026. Second Admission is expected to occur on 8 January 2026.

A separate announcement will be made following the General Meeting as to the results of the General Meeting and the total voting rights following Admission.

Unless otherwise defined, all capitalised terms used but not defined in this announcement shall have the meaning given to them in the announcement of the Fundraising made by the Company on 12 December 2025.

This announcement should be read in its entirety. In particular, the information in the "Important Notices" section of the announcement should be read and understood.
