Notes on appointing a proxy

1. If you wish to appoint as your proxy someone other than the Chair of the Meeting, insert the name of your chosen proxy in the space provided in the first box on the Proxy Form (and, if your proxy is participating in the electronic meeting, refer to Note 10 below for information on how to obtain log in details). If the proxy is being appointed in relation to part of your holding only, enter the number of shares over which the proxy is authorised to act as your proxy in the box next to the proxy's name. If this box is left blank, your proxy will be authorised in respect of your full voting entitlement.
2. To appoint more than one proxy, you should obtain additional Proxy Forms from the company's registrar, Computershare, or you may photocopy the Proxy Form. Ensure that you specify the number of shares over which each proxy can act, as in Note 1 above. Multiple Proxy Forms must be returned together in the same envelope.
3. To be valid, the Proxy Form and the power of attorney or other authority (if any) under which it is signed and dated must be received by Computershare by 2.30pm on Friday 1 May 2026.
4. The "Vote withheld" option is provided to enable a member to withhold their vote on any particular resolution. 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 votes "For" or "Against" a resolution.
5. To register the appointment of a proxy electronically, log on to www.investorcentre.co.uk/eproxy using the Control Number, PIN and Shareholder Reference Number printed overleaf and follow the instructions provided. The proxy appointment must be registered on the website by 2.30pm on Friday 1 May 2026.

6. In the case of a corporate shareholder, the proxy appointment must be under seal or signed by a duly authorised officer, attorney or other person.

7. In the case of joint holdings, the vote of the first named in the register of members will be accepted to the exclusion of the votes of other joint holders.

8. If no specific directions are given, the proxy will vote or abstain from voting as they think fit on the specified resolutions and, unless instructed otherwise, the person appointed proxy may also vote or abstain from voting as they think fit on any business (including amendments to resolutions) which may properly come before the Meeting.
9. A proxy need not be a member of the company, but must attend the Meeting to represent you. If no name is inserted in the box provided, the Chair of the Meeting will be deemed to be appointed as the proxy.
10. If your appointed proxy will be attending the Meeting electronically, once your proxy appointment has been received and processed by Computershare, you or your appointed proxy should contact Computershare, before 2.30pm (UK time) on Friday 1 May 2026, to obtain log in details to enable your appointed proxy to access the electronic AGM. Computershare can be contacted on +44 (0) 370 707 1595 (please use the country code if calling from outside the UK). Lines are open 8.30am to 5.30pm Monday to Friday (excluding public holidays in England & Wales).
11. Any alteration to the Proxy Form should be initialled by the person who signed it.
12. The completion and return of the Proxy Form will not prevent a member from participating in and voting at the Meeting, either electronically or in person, if they wish to do so.
