Grant of Share Options and PDMR Dealings

Grant of New Options

Haydale (AIM: HAYD), the advanced materials group, announces that on 7 August 2025 the Company approved the grant of options under the 2020 EMI Scheme as amended ("2020 EMI Scheme"), to certain directors of the Company ("Directors"), certain directors of the Company's subsidiaries ("Subsidiary Directors") and other staff of the Group, over an aggregate 36,439,568 ordinary shares of 0.01p ("New Options") each in the capital of the Company ("Ordinary Shares"), representing 0.8 per cent. of the Company's issued share capital.  The award has been made in recognition of the continued support and contribution of staff during the Company's operational turnaround, including voluntary salary reductions, and is intended to retain and incentivise key personnel through this transitional phase.

Terms of the New Options

The New Options granted under the 2020 EMI Scheme recognise the differing levels of voluntary salary reduction undertaken by management and staff during the Company's operational turnaround and are structured accordingly.

New Options granted to members of the senior management team (including Directors and Subsidiary Directors), who have continued to work full time but whose salary has been reduced as part of the Company's cost-saving measures, have an exercise price of 0.45 pence per Ordinary Share, representing the same price paid by investors in the recent fundraising completed on 27 June 2025 and a 22.4% discount to the mid-market closing price on the date of grant.

New Options granted to other employees, whose working hours and salary were reduced proportionally as part of the Company's cost-saving measures, have an exercise price of 0.58 pence per Ordinary Share, being the mid-market closing price of the Company's Ordinary Shares on the date of grant.

All New Options will vest and become exercisable on 30 June 2026, provided the relevant participant remains in continuous employment with the Company or any member of the Group (and has not served notice of resignation) as at that date. No other vesting criteria, performance hurdles, or accelerated vesting provisions apply.

Details of resultant holdings

Following the New Options grant, details of Options held by Directors, PDMRs and other employees of the Company and its subsidiaries, are as follows:
