If you return your Form of Proxy and intend to join the video webcast, please make a note of these numbers. Please also refer to the Notice of Meeting for instructions on how a proxy or corporate representative can join the meeting.
• 1. Entitlement to attend and vote at the AGM and the number of votes which may be cast thereat will be determined by reference to the Register of Members of the Company at 6pm on Tuesday 7 May 2024 (or, in the event of any adjournment, 6pm on the date which is two working days prior to the adjourned meeting). Changes to entries on the Register of Members after that time shall be disregarded in determining the rights of any person to attend and vote at the AGM.
• 1. Every holder has the right to appoint some other person(s) of their choice, who need not be a shareholder, as their proxy to exercise all or any of their rights, to attend, speak and vote on their behalf at the meeting. If you wish to appoint a person other than the Chair, please insert the name of your chosen proxy holder in the space provided (see reverse). If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name (see reverse) the number of shares in relation to which they are authorised to act as your proxy. If returned without an indication as to how the proxy shall vote on any particular matter, the proxy will exercise their discretion as to whether, and if so how, they vote (or if this proxy form has been issued in respect of a designated account for a shareholder, the proxy will exercise their discretion as to whether, and if so how, they vote).

• 1. The 'Vote Withheld' option overleaf is provided to enable you to abstain on any particular resolution. However, it should be noted that a 'Vote Withheld' is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' and 'Against' a resolution.

To appoint one or more proxies or to give an instruction to a proxy (whether previously appointed or otherwise) via a designated voting platform, any such messages must be received by the issuer's agent prior to the specified deadline within the relevant system. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the relevant designated voting platform) from which the issuer's agent is able to retrieve the message.
