• 3. 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. The Company may treat as invalid a proxy appointment sent via a designated voting platform in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
• 4. To be valid, this form of proxy must be received by the Registrar no later than 1.00 pm on Thursday, 19 February 2026. Please return to Computershare in the business reply paid envelope provided.

• 5. In the case of a corporation this form of proxy should be given under its common seal or signed on its behalf by an attorney or a duly authorised officer.

• 6. In the case of joint holders, the vote of the senior holder who tenders a vote whether in person or by proxy will be accepted to the exclusion of the other joint holders. For this purpose, seniority is determined by the order in which the names stand in the register of members in respect of the holding.

• 7. Shareholders have the right to appoint some other person(s) of their choice, who need not be a member of the Company 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 Chairman, please insert the name of your chosen proxy holder in the space provided (see reverse).
• 8. 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 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).
• 9. To appoint more than one proxy, (an) additional proxy form(s) may be obtained by contacting the Registrar's helpline on 0370 707 4027 or you may photocopy the reverse 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 they are authorised to act as your proxy. 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 returned together in the same envelope.
• 10. Appointment of a proxy does not prevent a member from attending and voting in person should he or she so wish.
• 11. A vote withheld is not a vote in law and will not be counted in the calculation of the proportion of votes 'for' and 'against' a resolution.

To be valid, all votes must be lodged at the office of the Company's registrars at: Computershare Investor Services PLC, The Pavilions, Bridgwater Road, Bristol BS99 6AH by 1.00 pm on Thursday, 19 February 2026.
