Explanatory Notes:

1. Every holder has the right to appoint some other person(s) of their choice, who need not be a shareholder as his/her proxy to exercise all or any of his/her rights, to attend, speak and vote on their behalf, at the Meeting. If you wish to appoint a person other than the Chair of the Meeting, please insert the name of your chosen proxy holder in the space provided (see reverse). If no name is inserted in the space provided then the Chair of the Meeting will be deemed appointed as the proxy. 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 the proxy is authorised to act. If left blank your proxy will be deemed to be authorised in respect of your full voting entitlement (or if this proxy form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).

2. To appoint more than one proxy, (an) additional proxy form(s) may be obtained by contacting the Registrar's helpline on (00) 353 1 447 5566 or you may photocopy the reverse only of this form. Please indicate in the box next to the proxy holder's name (see reverse) the number of shares in relation to which the proxy is authorised to act. Please also indicate by ticking the box provided if the proxy instruction is one of multiple instructions being given. All forms must be signed and should be returned together in the same envelope with any power of attorney or other authority under which the form(s) is executed or a notarially certified copy thereof. Please note that you may not appoint more than one proxy to exercise rights attached to any one share.

3. 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. On

any other business which properly comes before the Meeting (including any motion to amend any resolution or to adjourn the Meeting) the proxy will vote or abstain at his/her discretion.

1. Pursuant to regulation 41 of the Uncertificated Securities Regulations 2001, entitlement to attend and vote at the Meeting and the number of votes which may be cast thereat will be determined by reference to the Register of Members of the Company as at 6p.m. on 1 May 2026. 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 Meeting.

2. To appoint one or more proxies or to give an instruction to a proxy (whether previously appointed or otherwise) via the CREST system, CREST messages must be received by the issuer's agent (ID number 3RA50) not later than 12 noon on 1 May 2026. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the CREST system) from which the issuer's agent is able to retrieve the message. The Company may treat as invalid a proxy appointment sent by CREST in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001 (as amended).

3. The above is how your address appears on the Register of Members. If this information is incorrect, please ring the Registrar's helpline on (00) 353 1 447 5566 to request a change of address form or go to www.computershare.co.uk to use the online Investor Centre service.

4. In the case of joint holders, the vote of the first-named in the Register of Members of the Company will be accepted to the exclusion of that of other joint holders.

5. Any alterations made to this form should be initialled by the person who signs it.

6. Completion and return of a form of proxy does not prevent a member from attending and voting at the Meeting.

Kindly Note: This form is issued only to the addressee(s) and is specific to the unique designated account printed hereon. This personalised form is not transferable between different (i) account holders; or (ii) uniquely designated accounts. The Company and Computershare Investor Services (Ireland) Limited accept no liability for any instruction that does not comply with these conditions.
