Notification of Transactions of Persons Discharging Managerial

Responsibilities ('PDMRs')

This announcement is made in accordance with Article 19 of the Market Abuse Regulation ('MAR') and relates to the acquisition of shares by the following Group Executive Committee members, who are also PDMRs, under the Company's Long Term Performance Plan ('LTPP').

These awards relate to the 2021 LTPP and are referred to in the Company's 2023/24 Annual Report and Accounts. The awards were conditional on continued employment with the Company and on the satisfaction of the performance conditions approved by the Remuneration Committee, which (after tax on the gross award) must be retained until the shareholding requirement is met, and in any event for Executive Directors two years after receipt. This award is subject to malus and clawback provisions.

The Company also announces a correction to the announcement made on 14 June 2024. On 3 July 2024 the Company was notified that due to an administration error, it was incorrectly announced that Andy Agg, Chief Financial Officer, sold 1,335 rights under the Share Incentive Plan pursuant to the 2024 Rights Issue.
