HAYDALE GRAPHENE INDUSTRIES PLC

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

Result of Fundraising

Haydale (AIM:HAYD), the global advanced materials group, is pleased to announce that further to its announcement at 3.00 pm (the "Launch Announcement"), it has successfully completed the Fundraising which is now closed.

The Fundraising has raised in aggregate £5.0 million through the Placing and Subscription of 1,000,000,000 New Ordinary Shares, all at the Issue Price of 0.5 pence per Ordinary Share.

In addition to the Placing, the Company is also providing Retail Investors with the opportunity to subscribe for an aggregate of up to 200,000,000 Retail Shares at the Issue Price via the Bookbuild platform, to raise up to approximately £1.0 million (before expenses). The Retail Offer is due to close at 12.00 noon on 22 September 2023 and the results of the Retail Offer will be announced separately thereafter.

As set out in the Launch Announcement the net funds raised by the Fundraising will be used to fund the general working capital needs of the business.

Related Party Transactions

Keith Broadbent, David Banks, Theresa Wallis and Patrick Carter, all being Directors of the Company, have conditionally subscribed for an aggregate of 8,000,000 New Ordinary Shares through the Subscription (the "Participating Directors"). It is expected that the Participating Directors' interests following completion of the Fundraising (assuming full take up under the Retail Offer) will be as follows:

*Assuming the Retail Offer is subscribed in full

The issue of New Ordinary Shares to the Participating Directors constitutes a related party transaction pursuant to Rule 13 of the AIM Rules by virtue of their status as Directors of the Company. The independent directors, being all Directors except the Participating Directors, having consulted with the Company's nominated adviser, Cavendish, consider that the terms of the participation in the Fundraising by the Participating Directors are fair and reasonable insofar as the Company's Shareholders are concerned.

Admission and Total Voting Rights

The Placing, Subscription and Retail Offer of in aggregate the 1,200,000,000 New Ordinary Shares (assuming full take up under the Retail Offer) are conditional upon, among other things, the passing of the Resolutions at the General Meeting. The EIS/VCT Placing is conditional, amongst other things, on the passing of the Resolutions, the Placing Agreement not having been terminated and EIS/VCT Admission occurring on or before 8.00 a.m. on 4 October 2023 (or such later date as finnCap and the Company may agree being not later than 8.00 a.m. on 31 October 2023).  The General Placing is conditional, amongst other things, on the passing of the Resolutions, the Placing Agreement not having been terminated, EIS/VCT Admission having occurred and General Admission occurring on or before 8.00 a.m. on 5 October 2023 (or such later date as finnCap and the Company may agree being not later than 8.00 a.m. on 31 October 2023).

It is expected that EIS/VCT Admission will take place at 8.00 a.m. on 4 October 2023 and that dealings in the Existing Adjusted Ordinary Shares and the EIS/VCT Placing Shares on AIM will commence at the same time. It is expected that General Admission will take place at 8.00 a.m. on 5 October 2023 and that dealings in the General Placing Shares, the Subscription Shares and the Retail Offer Shares on AIM will commence at the same time.

On Admission, the total number of Ordinary Shares in issue will be 1,985,853,051 (assuming full take up under the Retail Offer) with the Company holding no Ordinary Shares in treasury. Therefore the total number of voting rights will also be 1,985,853,051. This figure may be used by shareholders 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 share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.

Posting of Circular and Notice of General Meeting

A Circular containing the Notice of General Meeting is being posted to Shareholders on 16 September 2023. The Company will also publish this on its website pursuant to AIM Rule 26. The General Meeting will be held on 3 October 2023 at 11:00 a.m. at the offices of Fieldfisher LLP, 9th Floor, Riverbank House, 2 Swan Lane, London EC4R 3TT, notice of which will be set out at the end of the Circular.
