NOTES

• (1) Shareholder participation and engagement remains important to us and as a result we are pleased to be able to provide a facility for shareholders to view and listen to the business of the meeting and raise questions during the meeting at the invitation of the Chair through the Company's webcasting platform operated by BRR Media (the "Webcasting Platform"), as described in further detail in the Notes to the Notice of AGM. 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 at https://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 6 and 7 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. Box 7117, Dublin 2, Ireland if delivered by post or at Link Registrars Limited, Suite 149, The Capel Building, Mary's Abbey, Dublin 7, D07 DP79, Ireland if delivered by hand during normal business hours so as to be received by no later than 10:30am (Irish Time) on 2 May 2023 (or, in the case of an adjournment, no later than 48 hours before the time fixed for holding the adjourned meeting) or in the case of a poll, at least 48 hours before the time appointed for the taking of the poll. 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. For information only

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. You will need to register for the Share Portal by clicking on "registration section" (if you have not registered previously) and following the instructions. Shareholders will be asked to enter their Investor Code (IVC) as printed on the top of the Form of Proxy and agree to certain conditions. Link Registrars Limited, the company's registrar, has launched a shareholder app: LinkVote+. It's 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 rather than through the post. The app is available to download on both the Apple App Store and Google Play, or by scanning the relevant QR code below.

• (6) In respect of CDI Holders, Euroclear UK & International Limited ("EUI"), the operator of CREST, has arranged for voting instructions relating to the CDIs held in CREST to be received by Broadridge. Further details on this service are set out on the "All you need to know about SRD II in Euroclear UK & Ireland" webpage of the Euroclear Bank website (www.euroclear.com) which is accessible to CREST participants (see the section entitled "CREST International Service – Proxy Voting"). If you are a CDI Holder, you will be required to make use of the EUI proxy voting service facilitated by Broadridge Global Proxy Voting service in order to receive meeting announcements and send back voting instructions as required. To facilitate client set up, if you hold CDIs and wish to participate in the Broadridge Global Proxy Voting service, you will need to complete the following steps:
• ^l Register for an account with EUI at the following web address: https://www.euroclear.com/users/en/registration-choice.html.
• ^l Complete a Meetings and Voting Client Set-Up Application Form (the "EUI Application Form"), which will be available at the following link once you have logged in to your EUI account: Meetings and Voting Client Set-up Form (CRT408).
• ^l A copy of the completed EUI Application Form must be returned to EUI by an authorised signatory (i.e. a nominated representative of the CDI Holder) with a second authorised signatory copied in for verification purposes (where appropriate) using the following email address: eui.srd2@euroclear.com.
• ^l Fully completed and returned EUI Application Forms will be shared with Broadridge by EUI. This will enable Broadridge to contact you and share further detailed information on the service offering and initiate the process for granting your access to the Broadridge platform. Should shareholders have any queries on the Broadridge service offering, Broadridge can be contacted by telephone on +1 800 353 0103 during normal US (Eastern Time) business hours.

Once CDI Holders have gained access to the Broadridge platform (by following the instructions set out above), they can complete and submit proxy appointments (including voting instructions) electronically. Broadridge will process and deliver any such proxy voting instructions received from CDI Holders by the Broadridge voting deadline date to Euroclear Bank by its cut-off time and to agreed market requirements. Alternatively, a CDI Holder can send a third party proxy voting instruction through Broadridge in order to appoint a third party (who may be a corporate representative or the CDI Holder themselves) to attend and vote at the meeting the number of shares specified in the proxy instruction (subject to the Broadridge voting deadline). There is no facility to offer a letter of representation/appoint a corporate representative other than through the submission of third party proxy appointment instructions through Broadridge.

Broadridge's voting deadline is expected to be two business days prior to Euroclear Bank's voting instruction deadline as set out below and is expected to be close of business on Thursday, 27 April 2023. As stated above, CDI Holders should please consult with their stockbrokers to confirm any relevant Broadridge deadlines.

CDI Holders should pay close attention to any notices specifically relating to the AGM and are strongly encouraged to familiarise themselves with the arrangements with Broadridge, including the voting deadlines and procedures and to take, as soon as possible, any further actions required by Broadridge before they can avail of this voting service.

The Company understands that Broadridge will use best endeavours to accept late votes, changes and cancellations from a CDI Holder after the voting deadline but there is no guarantee that these will be processed within the requisite timeframes.

Should you have any queries in relation to completing and submitting proxy appointments (including voting instructions) electronically via Broadridge, please contact your dedicated client service representative at Broadridge.
