Proxy voting

Please submit your proxy voting appointment electronically at www.signalshares.com or, if you hold shares in CREST, by using the CREST electronic proxy appointment service. If you are an institutional investor, you may also appoint a proxy electronically via the Proxymity platform. The proxy voting instructions must be received by Link Group no later than 12.00 noon on 11 March 2024.

To vote online you will need to log in to your share portal account or register for the share portal if you have not already done so.

To register for the share portal you will need your investor code which can be located on your share certificate or your dividend tax voucher. Once registered you will immediately be able to vote.

Link Group, the Company's Registrar, has also launched a shareholder app LinkVote+. The app is free to download and use and gives shareholders the ability to access their shareholding record at any time and allows users to submit a proxy appointment quickly and easily online. The app is available to download on both the Apple App Store and Google Play.

If you are unable to locate any of the documents on the web page, need help with voting online or require a paper proxy form, please contact our Registrar, Link Group, by email to shareholderenquiries@linkgroup.co.uk or you may call Link Group on +44 (0)371 664 0300. Calls are charged at the standard geographic rate and will vary by provider. Calls outside the United Kingdom will be charged at the applicable international rate. Lines are open between 9.00am and 5.30pm Monday to Friday, excluding public holidays in England and Wales.

We would like to take this opportunity to thank you for having consented to receive these documents via the Company's website rather than in hard copy form, as this reduces paper and improves the efficiency of our shareholder communications.

Yours faithfully,
