Guidance notes

1. Eligibility to attend and vote

Shareholders' eligibility to attend, speak and vote at the GM, either in person or by proxy, will be determined by reference to the register of members of the Company (the "Register of Members") as at close of business on Tuesday, 9 December 2025 (or not less than 48 hours before the time of the GM if it is adjourned). Changes to the Register of Members after this time will be disregarded in determining the rights of any person to attend, speak and vote at the GM.

The Directors strongly recommend that shareholders vote by proxy as soon as possible and to appoint the Chair of the Meeting as their proxy. Submitting a proxy form in advance of the GM will not prevent a shareholder from attending and voting at the Meeting in person. If you have submitted a proxy form and attend in person, please mention this upon registration.

2. Resolutions

Details of the resolutions are set out in the Notice.

3. Appointing a proxy or multiple proxies

Please enter the proxy holder's name. The proxy does not need to be a member of the Company. If no name is entered, the Chair of the GM will be appointed.

Indicate in the box next to the proxy holder's name the number of shares in relation to which they are authorised to act as your proxy. If no number is entered, they will be authorised in respect of your full voting entitlement.

You may appoint more than one proxy provided that each proxy is appointed to exercise the rights attached to different shares held by you. Please indicate if the proxy appointment is one of multiple appointments. If you wish to appoint more than one proxy by post, each proxy must be appointed on a separate proxy form.

Additional paper proxy forms may be obtained by contacting Equiniti Limited on +44 (0)371 384 2649. Lines are open from 8.30 am to 5.30 pm, Monday to Friday excluding public holidays in England and Wales. Alternatively, you may photocopy the proxy form the required number of times before completing it.

When two or more valid but differing appointments of a proxy are received in respect of the same share for use at the same meeting or poll, the one which is last received (regardless of its date or of the date of its signature) will be treated as replacing and revoking the others as regards that share; if the Company is unable to determine which was last received, none of them will be treated as valid in respect of that share.

4. Proxy voting discretion

If you have not given specific instructions on how your proxy should vote in respect of any resolution, your proxy will have discretion to vote on that resolution, in respect of the number of shares stipulated in the proxy or your total holding if no number has been given, as they see fit. Your proxy can vote, or abstain from voting, as they decide on any other business which may validly come before the GM.

5. Signing of proxy form

The proxy form should be signed by the registered shareholder, and, if not signed by the registered shareholder themselves, must be accompanied by the original power of attorney or other document giving authority to the signatory or a notarised/certified copy thereof.

In the case of joint holders, any joint holder may sign this proxy form, but the vote of the person whose name appears first in the Register of Members in respect of the holding or his proxy will be accepted to the exclusion of the votes of other joint holders or their proxies.

If a shareholder is a corporation, the proxy should be given under the common seal or under the hand of an officer or attorney duly authorised in writing.

6. Returning paper proxy forms

A pre-paid envelope is enclosed for UK postage only. If posting from outside the UK, IOM or Channel Islands, the appropriate postage must be paid. Forms for multiple proxy appointments must be returned together in the same envelope.

7. Vote withheld

The 'Vote Withheld' option is provided to enable you to abstain on any particular resolution. However a 'Vote Withheld' is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' or 'Against' a resolution.

8. CREST members

CREST members may appoint a proxy or proxies through the CREST electronic proxy appointment service by using the procedures described in the CREST manual (available at www.euroclear.com). CREST Personal Members or other CREST sponsored members and those CREST members who have appointed a service provider(s) should refer to their CREST sponsor or voting service provider(s) who will be able to take the appropriate action on their behalf.

In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with Euroclear UK & Ireland Limited's specifications and must contain the information required for such instructions, as described in the CREST Manual (available at www.euroclear.com). The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by Equiniti Limited (CREST Participant ID RA19) by 10.00 am (U.K. time) on Tuesday, 9 December 2025. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which Equiniti Limited are able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

9. Proxymity members

If you are an institutional investor, you may be able to appoint a proxy electronically via the Proxymity platform. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 10.00 am (U.K. time) on Tuesday, 9 December 2025 in order to be considered valid.

10. Change of address

Please do not use this proxy form to communicate a change of address or any other notifications. Please contact Equiniti Limited separately and they will be pleased to assist you.

11. Electronic communications

Please note that any electronic communication, including an electronic proxy form, found to contain a computer virus will not be accepted.

The use of the online voting service (via a portfolio at www.shareview.co.uk) is governed by Equiniti Limited's conditions of use set out on the respective website.
