Notes on Form of Proxy

1. The resolutions are set out in full in the 2026 AGM notice dated 20 March 2026.
2. As a shareholder you are entitled to appoint one or more proxies to exercise all or any of your shareholder rights to attend and to speak and vote on your behalf at the meeting. The appointment of the Chair of the meeting as proxy has been included for convenience. To appoint any other person as a proxy, delete the words "the Chair of the meeting or" and insert the full name of your proxy in the space provided. A proxy need not be a shareholder of the Company. If you wish your proxy to speak at the meeting, you should appoint a proxy other than the Chair of the meeting and give your instructions to that proxy. If the proxy is being appointed in relation to part of your holdings only, please enter in the space provided the number of shares in relation to which they are authorised to act. If this box is left blank, they will be authorised in respect of your entire shareholding.
3. Completion and submission of the Form of Proxy will not prevent you from attending the meeting and voting at the meeting in person, in which case any votes cast by your proxy will be excluded.
4. To be valid the Form of Proxy should be completed, signed and delivered (together with the power of attorney or other authority (if any) under which it is signed, or a notarially certified copy of such power or authority) to the Company's registrars, MUFG Corporate Markets, PXS 1, Central Square, 29 Wellington Street, Leeds LS1 4DL not later than 10:00 a.m. (BST) on 27 April 2026 or, in the case of a poll taken subsequent to the date of the meeting, or any adjourned meeting, not less than 24 hours before the time appointed for the taking of the poll which is taken more than 48 hours after the day of the meeting or adjourned meeting.
5. In the case of a company being a shareholder then this proxy form must be executed under its common seal or signed on its behalf by an officer of that company or an authorised attorney for that company.
6. You may appoint more than one proxy provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. Shareholders who intend to appoint more than one proxy can obtain additional Forms of Proxy from MUFG Corporate Markets via email at shareholderenquiries@cm.mpms.mufg.com or on 0371 664 0300 if you are phoning from the United Kingdom or +44 (0) 371 664 0300 if you are calling outside the United Kingdom. Calls are charged at the standard geographical rate and will vary by provider. Calls from outside of the United Kingdom will be charged at the applicable international rate. Lines are open 9:00 a.m. to 5:30 p.m. (BST) Monday to Friday (excluding public holidays in England and Wales). Alternatively, the Form of Proxy provided may be photocopied prior to completion. The Forms of Proxy should be returned in the same envelope and each should indicate that it is one of multiple appointments being made. If you return more than one proxy appointment, either by paper or electronic communication, the appointment received last by the Company's registrar before the last time for the receipt of proxies will take precedence.
7. 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 votes of any other joint holders. For these purposes, seniority shall be determined by the order in which the names stand in the Company's shareholders' register in respect of the joint holding.
8. A "vote withheld" option has been included on the Form of Proxy. The legal effect of choosing this option on any resolution is that you will be treated as not having voted on the relevant resolution. The number of votes in respect of which votes are withheld will, however, be counted and recorded, but disregarded in calculating the number of votes for or against each resolution.
9. Shares held in uncertificated form (i.e. in CREST) may be voted through the CREST Proxy Voting Service in accordance with the procedures set out in the CREST manual. Further details are set out in the AGM notice dated 20 March 2026.
10. If you are an institutional investor you may be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Registrar. For further information regarding Proxymity, please go to www.proxymity.io and refer to the AGM notice.
11. Alternatively, you can vote online at www.signalshares.com or via the VOTE+ app (refer to the AGM notice for further details).
