Result of Fundraising

Haydale (AIM:HAYD), the global advanced materials group, is pleased to announce that further to its announcement at 14:15 p.m. 25 October 2024 (the "Launch Announcement"), it has successfully completed the Fundraising which is now closed.

The Fundraising has successfully raised in aggregate £3.0 million. This comprises £2.5 million raised through the Placing and Subscription of 1,895,858,186 New Ordinary Shares at the Issue Price of 0.1325 pence per New Ordinary Share, and £0.5 million raised through subscriptions for Convertible Loan Notes from Octopus Investments. Further details on the Fundraising are included in the Launch Announcement.

In addition to the Placing, Subscription and Convertible Loan Notes the Company has also announced that it is providing Retail Investors with the opportunity to subscribe for an aggregate of up to 377,358,490 Retail Shares at the Issue Price via the Bookbuild platform, to raise up to an additional £0.5 million (before expenses). The Retail Offer is due to close at 4.30 p.m. today 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.

Updated Timetable

The Company confirms that the timings of the Fundraising have been amended as follows:

Related Party Transactions

As noted in the Launch Announcement, David Banks, Keith Broadbent, Theresa Wallis and Gareth Kaminski-Cook being Directors of the Company, have indicated their intention to subscribe New Ordinary Shares as part of the Fundraising (the "Participating Directors"). Gareth Kaminski-Cook has also increased his subscription since the Launch Announcement to 3,773,584 Ordinary Shares. Therefore, the Participating Directors are subscribing for in aggregate 41,509,431 New Ordinary Shares. 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 director for the purposes of this opinion, Patrick Carter, having consulted with the Company's nominated adviser, Cavendish, considers 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.

Additionally, the issuance of £0.5 million of Convertible Loan Notes to Octopus Investments via Octopus AIM VCT and Octopus AIM VCT 2 for £0.3 million and £0.2 million, respectively, constitutes a related party transaction pursuant to Rule 13 of the AIM Rules by virtue of their status as Substantial Shareholder of the Company. The Directors, having consulted with the Company's nominated adviser, Cavendish, consider that the terms of the participation in the Fundraising by Octopus AIM VCT and Octopus AIM VCT 2 is fair and reasonable insofar as the Company's Shareholders are concerned.

Admission

The New Ordinary Shares, when issued, will be fully paid and will rank pari passu in all respects with the Existing Adjusted Ordinary Shares, including the right to receive all dividends and other distributions declared, made or paid after the date of issue.

Applications will be made to the London Stock Exchange for admission of the New Ordinary Shares and the Existing Adjusted Ordinary Shares to trading on AIM. It is expected that Admission will take place on or before 8.00 a.m. on 14 November 2024 and that dealings in the New Ordinary Shares and Existing Adjusted Ordinary Shares on AIM will commence at the same time.
