Grant of share options and PDMR dealings

Haydale (AIM: HAYD), the global advanced materials group, announces that on 20 January 2022 the Company approved the following:

2.    under the Haydale Technologies, Inc ("HTI") Stock Appreciation Rights Plan 2020 ("2020 SAR"), the grant of stock appreciation rights ("Stock Appreciation Rights") to certain employees of the Group's wholly owned US subsidiary, HTI, over an aggregate 2,750,000 Ordinary Shares pursuant to the 2020 SAR rules.

(The 2020 EMI Scheme and the 2020 SAR, together the "Share Schemes". The new options or Stock Appreciation Rights granted under the Share Schemes, together the "January 2022 Grants").

Background to the January 2022 Grants

The Company adopted the Share Schemes to enable it to retain and incentivise staff and to reward them for the achievement of its longer-term objectives. The Share Schemes have certain performance criteria to ensure that value is created for shareholders before  any value is delivered to Directors and key staff.   The January 2022 Grants will broaden the coverage of the Share Schemes and also include those who have more recently joined the Group.  The January 2022 Grants will also award options to those who received an initial award on 13 January 2020 to reflect, in some cases, changes in responsibility and, in general, to reward them for their perseverance and hard work during what has been a challenging period for all.

Terms of the January 2022 Grants

All of the January 2022 Grants have an exercise price of 6.25p per Ordinary Share (being a 12.6% premium to the closing mid-market price of the Company's Ordinary Shares on 20 January 2022, the day of the approval of the January 2022 Grants) and can only be exercised between the third and tenth anniversary of the awards. The proportion of the awards made by the January 2022 Grants that are capable of vesting is dependent on certain performance criteria, directly linked to the performance of the Company's share price over the period to 30 September 2025 as follows:

There are no other vesting criteria for the January 2022 Grants. If the share price does not reach the target price by their respective dates, that portion of the award will lapse.

The January 2022 Grants represents approximately 2.3% of the Company's issued ordinary share capital. Of the January 2022 Grants, 3,400,000 options were granted to Directors of the Company and its subsidiaries, as follows:

The Company's Remuneration Committee retains the ability to amend the performance conditions for the January 2022 Grants and for future grants to ensure that such grants achieve the stated purpose.

Following the January 2022 Grants, the Company's total number of Options, SARs and Warrants outstanding as at the date of this announcement is 49,300,000 representing approximately 8.8% of the Company's existing issued share capital.

The number of Ordinary Shares currently in issue is 510,335,691 and it is this number that has been used to calculate the above percentage shareholdings.
