Notice of 2025 Annual General Meeting

A letter from the Chair of Grafton Group plc is set out on pages 7 to 9 of this document.

Your attention is drawn to the Notice of the Annual General Meeting (“AGM”) to be held at 10:30am (Irish Time) on Thursday, 8 May 2025 at the Irish Management Institute (IMI) Conference Centre, Sandyford Road, Dublin 16, D16 X8C3, Ireland which is set out on pages 10 to 13 of this document.

A Form of Proxy for use at the meeting is enclosed. The process for appointing a proxy and/or voting at the AGM will depend on the manner in which you hold your Ordinary Shares in the Company.

For shareholders whose names appear on the register of members of the Company (the “Register of Members”) (i.e. those who hold ordinary shares of the Company (“Ordinary Shares”) in book-entry form directly on the Register of Members and who therefore do not hold their interests in Ordinary Shares as Belgian law rights through the Euroclear Bank SA/NV (“Euroclear Bank”) system (the “EB System”) (“EB Participants”) or as CREST Depositary Interests (“CDIs”) through the CREST system (“CREST”)), the Form of Proxy must be completed and returned to the Company’s registrars, MUFG Corporate Markets (the “Registrar”) at P.O. Box 7117, Dublin 2, Ireland if delivered by post or to MUFG Corporate Markets, 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 Tuesday, 6 May 2025. Alternatively, you may appoint a proxy electronically by visiting the website of the Company’s Registrars 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. You will need your Investor Code (“IVC”) which can be found at the top of your Form of Proxy.

Additionally, the Registrar has launched a shareholder app: Vote+. 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.

Further instructions on how to appoint a proxy are set out on the Form of Proxy.

Persons who hold their interests in Ordinary Shares as Belgian law rights through the EB System or as CDIs through CREST should consult with their stockbroker or other intermediary at the earliest opportunity for further information on the processes and timelines for submitting proxy votes for the AGM through the respective systems.

For the avoidance of doubt, all resolutions at the AGM will be decided on a poll at the demand of the Chair in accordance with the provisions of the Articles of Association of the Company and in line with current market practice.

Further Information for shareholders who hold their interests in Ordinary Shares as CDIs ("CDI Holders")¹

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 via a third party service provider, Broadridge Financial Solutions Limited ("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:

• Register for an account with EUI at the following web address: https://www.euroclear.com/users/en/registration-choice.html.
• Complete a Meeting 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).

of the CDI Holder also copied in for verification purposes using the following email address: eui.srd2@euroclear.com.

• Fully completed and returned EUI Application Forms will be shared with Broadridge by EUI.

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 Standard 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 the Broadridge platform 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 for the number of Ordinary 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, 1 May 2025. 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 Broadridge’s arrangements, 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 its best endeavours to accept late votes, changes to votes and cancelled votes from a CDI Holder after their 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.

Dear Shareholder,

Introduction

I am writing to you to explain the resolutions to be proposed at the forthcoming Annual General Meeting (the "AGM").

Your attention is drawn to the Notice of the AGM which will be held at 10:30am (Irish Time) on Thursday, 8 May 2025 at the IMI Conference Centre, Sandyford Road, Dublin 16, D16 X8C3, Ireland, which is set out on pages 10 to 13 of this document.

The following briefly explains the business to be transacted at the AGM:

Resolution 1 deals with reviewing the Company's affairs and considering the financial statements for the year ended 31 December 2024, together with the reports of the directors and statutory auditor thereon.

Resolution 2 proposes the approval and payment of a final dividend for the year ended 31 December 2024 of 26.5 pence per Ordinary Share in the capital of the Company to be paid on Thursday, 15 May 2025 to the holders of Ordinary Shares on the register of members of the Company at the close of business on Tuesday, 22 April 2025.

Resolution 3 proposes the re-election of directors. The Board has agreed that all Directors will retire and seek re-election at the forthcoming AGM. This is not required legally or by the Company's Articles of Association but is in line with best practice and the provisions of the 2024 UK Corporate Governance Code (as amended).

I recommend that each of the Directors going forward be re-elected at the 2025 AGM.

Resolution 4 is an advisory, non-binding resolution regarding the continuation in office of PricewaterhouseCoopers as Auditors of the Company.

Resolution 5 authorises the Directors to fix the remuneration of the Auditors for the year ending 31 December 2025.

---

In Resolution 6, the Board is proposing to submit the Annual Statement of the Chair of the Remuneration Committee and the Annual Report on Remuneration of the Remuneration Committee, as set out on pages 102 to 105 and 106 to 119 respectively of the 2024 Annual Report, to a non-binding advisory vote.

Resolution 7 is a special resolution which, if adopted, will maintain the existing authority in the Articles of Association which permits the Company to convene an Extraordinary General Meeting by giving at least 14 clear days' notice in writing where the purpose of the meeting is to consider an ordinary resolution. As a matter of policy, the 14 clear days' notice will only be utilised where the Directors believe that it is merited by the business of the meeting and is to the advantage of shareholders as a whole.

Special Business at AGM

In addition to the ordinary business to be transacted at the AGM, there are various items of special business which are described further below:

Resolution 8 - Authority to Allot Relevant Securities

In Resolution 8, shareholders are being asked to renew the Directors' authority to allot and issue shares. If adopted, this authority will authorise the Directors to issue shares up to a maximum aggregate nominal value of €3,287,488 (which represents one third of the nominal value of the existing issued ordinary share capital of the Company as at the latest practicable date before the publication of this AGM Circular). The authority under this resolution will expire at next year's AGM or 15 months after the forthcoming AGM, whichever is the earlier.

Resolution 9 - Authority to Dis-apply Statutory Pre-emption Rights

At the AGM held in 2024, shareholders gave the Directors power to allot shares for cash otherwise than in accordance with statutory pre-emption rights. That power will expire at the close of business on the date of the forthcoming AGM.

The Directors will, at the forthcoming AGM, seek power to allot shares for cash, otherwise than in accordance with statutory pre-emption rights, by way of rights issue or other issue up to the amount of the unissued share capital of the Company, or otherwise up to an aggregate nominal value of €491,873 on the basis that this limit shall apply to all allotments for cash and any treasury shares that may be reissued for cash. This limit is equivalent to approximately five per cent of the nominal value of the issued ordinary share capital of the Company. The power under this resolution will expire (under the Articles of Association of the Company) at next year's AGM or 15 months after the forthcoming AGM, whichever is the earlier.

Save for the allotment of shares in respect of the Company's employee share schemes, as at the date hereof, the Board has no current intention to exercise the authority sought pursuant to Resolutions 8 and 9 (as described above) and will only exercise these authorities if they consider it to be in the best interests of shareholders generally at that time. The number of treasury shares held by the Company as at the date hereof is 500,000, which is equivalent to approximately 0.25 per cent of the issued share capital of the Company (excluding treasury shares) as at the latest practicable date before the publication of this AGM Circular.

Resolution 10 - Authority to Make Market Purchases of the Company's Own Shares

At the 2024 AGM, shareholders gave the Company and/or any of its subsidiaries authority to make stock market purchases of up to 10 per cent of the Company's own shares. Under Resolution 10 shareholders are being asked to renew this authority.

---

The Directors monitor the Company’s share price and may from time to time exercise this power to make stock market purchases of the Company’s own shares, at price levels which they believe would increase the future earnings per share on those shares not purchased and where it would be in the best interests of the Company and its shareholders generally, after taking account of the Company’s overall financial position. The minimum price which may be paid for any market purchase of the Company’s own shares will be the nominal value of the shares and the maximum price which may be paid will be 105 per cent of the then average market price of the shares. The power under this resolution will expire (under the Articles of Association of the Company) at next year’s AGM or 15 months after the forthcoming AGM, whichever is the earlier.

Resolution 11 - Authority to Re-issue Treasury Shares

In Resolution 11, shareholders are being asked to sanction the price range at which any treasury share (that is a share of the Company redeemed or purchased and held by the Company rather than being cancelled) may be re-issued other than on the Stock Exchange. The maximum and minimum prices at which such a share may be re-issued are 120 per cent and 95 per cent, respectively of the average market price of a share calculated over the five business days immediately preceding the date of such re-issue.

Further Action

A Form of Proxy for use at the meeting is enclosed. The process for appointing a proxy and/or voting at the meeting will depend on the manner in which you hold your Ordinary Shares in the Company.

Further information on the conduct of the meeting together with the relevant voting/proxy appointment options and deadlines for the various shareholders of the Company are set out on pages 1 to 4 of this AGM Circular and in the notes to the Notice of AGM.

RECOMMENDATION

Your Board considers that the proposals set out in resolutions 1 – 11 above are in the best interests of shareholders as a whole and recommends that you vote IN FAVOUR of resolutions 1 – 11 at the AGM.

All resolutions at the AGM will be decided on a poll at the demand of the Chair in accordance with the provisions of the Articles of Association of the Company and in line current market practice. The results will be published on the company’s website at https://www.graftonplc.com/investors/shareholder-services/shareholder-meetings/ as soon as possible after the conclusion of the AGM.

If you have any questions, please contact MUFG Corporate Markets on +353 (0) 1 553 0050. Lines are open 9:00am to 5:00pm (Irish Time) Monday to Friday, excluding Bank or Public Holidays in Ireland.

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, MUFG Corporate Markets 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.

MUFG Corporate Markets, the company's Registrar, has launched a shareholder app: Vote+. 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 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:

Further instructions on how to appoint a proxy are set out on the Form of Proxy.

1. 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:

• Register for an account with EUI at the following web address: https://www.euroclear.com/users/en/registration-choice.html.

---

• 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).

• 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 of the CDI Holder also copied in for verification purposes using the following email address: eui.srd2@euroclear.com.

• 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 you 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 Standard 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 the close of business on Thursday, 1 May 2025. As stated above, CDI Holders should 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 it best endeavours to accept late votes, changes to votes and cancelled votes 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.
