Shareholders wishing to vote at the AGM will still need to submit proxy voting instructions by the relevant deadlines before the AGM, as it will not be possible to vote at the AGM using the Webcasting Platform.

• (2) Any relevant updates regarding the conduct of the AGM, including any changes to the arrangements outlined in the accompanying AGM Circular, will be announced via a Regulatory Information Service and will be available on the website of the Company athttps://www.graftonplc.com/investors/ shareholder-services/shareholder-meetings/. Shareholders should monitor the Company's website for update announcements regarding the AGM in the event that circumstances change.

• (3) A member entitled to attend, speak, ask questions and vote is entitled to appoint a proxy to attend, speak, ask questions and vote on his/her behalf. A proxy need not be a member of the Company. Appointment of a proxy will not preclude a member from attending, speaking, asking questions and voting at the meeting should the member subsequently wish to do so.

• (4) A member may appoint more than one proxy to attend and vote at the meeting provided each proxy is appointed to exercise rights attached to different shares held by that member. Should you wish to appoint more than one proxy, please read these explanatory notes carefully. Holders of CREST Depositary Interests ("CDIs") ("CDI Holders") and/or participants of the Euroclear Bank SA/NV ("Euroclear Bank") system (the "EB System") ("EB Participants") wishing to attend, speak or ask questions at the AGM must arrange to have themselves appointed as their own proxy as explained in notes 5 and 6 respectively below.

• (5) For shareholders whose name appears on the register of members of the Company (i.e. those who hold their Ordinary Shares in certificated (i.e. paper) form and who therefore do not hold their interests in Ordinary Shares as Belgian law rights through the EB System or as CDIs through the CREST system ("CREST")), you may appoint a proxy by completing this Form of Proxy, making sure to sign and date the form at the bottom and return it to the Company's Registrars, Link Registrars Limited at P.O.

If you are appointing someone other than the Chair of the meeting as your proxy, then you must fill in the details of your representative at the meeting in the box in the top left corner of the Form of Proxy. If you appoint the Chair of the meeting or another person as a proxy to vote on your behalf, please make sure to indicate how you wish your votes to be cast by ticking the relevant boxes on the Form of Proxy. If no specific instructions are given, the proxy will vote or withhold your vote at his/her discretion. The "Abstain" option is provided to enable you to abstain on any particular resolution. It should be noted, however, that it is not a vote in law and will not be counted in the calculation of the proportion of votes for and against the resolution. Unless otherwise directed and in respect of any other resolutions moved during the AGM, the proxy will vote as he/she thinks fit or abstain from voting.

  Alternatively, a member may appoint a proxy or proxies electronically by logging on to the website of the registrars, Link Registrars Limited at www. signalshares.com and entering the Company name, Grafton Group plc.
