IMPORTANT COVID-19 NOTICE

Updated Arrangements for the Extraordinary General Meeting (“EGM”) of the Company to be Held at 10.30am on 21 January 2021.

A circular which contains the notice of EGM (the “Circular”), Form of Proxy and copies of the documents referred to in the Circular are available to view on the Company's website, https://www.graftonplc.com/investors/shareholder-services/shareholder-meetings/.

Grafton Group plc (the "Company") today announces that as the current COVID-19 measures published by the Government of Ireland provide that no organised indoor gatherings should take place, and in order to prioritise the health and safety of our shareholders, employees and other stakeholders, the Board is advising that regrettably it will not be possible for shareholders to attend the EGM in person but shareholders may participate in the meeting virtually  (ask questions and listen to the EGM) via the Lumi platform (as outlined below).

Although shareholders are not able to attend the EGM in person, shareholder participation and engagement remains important to us. The Board is therefore strongly encouraging all shareholders to:

• submit a proxy form by no later than 10.30 am on Tuesday, 19 January 2021; and
• appoint the Chairman of the meeting as their proxy rather than a named person to ensure they can exercise their vote and be represented at the EGM without attending in person.

Proxy forms can be submitted in advance of the EGM by availing of one of the following options:

• By post to the Company's Registrar, Link Registrars Limited, PO Box 1110, Maynooth, Co. Kildare, Ireland or by hand to Link Registrars Limited, Level 2, Block C, Maynooth Business Campus, Maynooth, Co. Kildare, W23 F854, Ireland.
• Electronically by accessing signalshares.com.
• Via the CREST System, where shares are held in CREST.

Shareholders may submit questions relating to the business of the meeting in advance (so as to be received by no later than 10.30 am on Tuesday, 19 January 2021) by email to [email protected] or by post to the Company Secretary, Grafton Group plc, Heron House, Corrig Road, Sandyford Business Park, Dublin 18, D18  Y2X6, Ireland. All correspondence should include sufficient information to identify a Shareholder on the Register of Members, for example, an IVC number, which is an 11 digit unique identifier printed on the proxy form.

Questions may be raised during the EGM through the Lumi platform as outlined below.

Logging in to the EGM via the Lumi platform

In order to ask questions and listen to the EGM via the Lumi platform, Shareholders will need to connect to the following site https://web.lumiagm.com. Lumi is compatible with the latest browser versions of Chrome, Firefox, Internet Explorer 11 (Internet Explorer V10 and lower are not supported), Edge and Safari and can be accessed using any web browser, on a PC or smartphone device.

Once Shareholders have accessed https://web.lumiagm.com from a web browser on a tablet or computer, they will be asked to enter the Lumi Meeting ID which is 138-517-438. Shareholders will then be prompted to enter their unique ‘Login Code’ and ‘PIN’. The Login Code is an 11 digit Investor Code (IVC), including any leading zeros. The PIN is the last 4 digits of the IVC. This will authenticate shareholders.

The IVC can be found on the proxy form, EGM attendance card, share certificate, or Signal Shares users (www.signalshares.com) will find it under ‘Manage your account’ when logged in to the Signal Shares portal. Shareholders can also obtain this by contacting Link Registrars Limited on +353 1 553 0050. Lines are open from 9.00 a.m. to 5.00 p.m. Monday to Friday, excluding Irish bank holidays.

Access to the Lumi platform for the purpose of the EGM will be available from 30 minutes before the meeting start time. During the EGM, you must ensure you are connected to the internet at all times in order to listen to the business of the EGM.  Therefore, it is your responsibility to ensure connection to the internet for the duration of the EGM.  If you wish to raise a question at the EGM, you must dial in to the conference call number which will be accessible once you have logged in to the Lumi platform. A user guide to the audio webcast is available on our website at: https://www.graftonplc.com/investors/shareholder-services/shareholder-meetings/.

A duly appointed proxy or corporate representative should get the necessary IVC and PIN from the shareholder appointing them.

If Shares are held within a nominee, Shareholders will need to contact their nominee in order to arrange for the Login Code and PIN to be sent to them ahead of the meeting.

Shareholders will still need to submit their proxy form by the relevant deadline before the EGM, as it will not be possible to vote using the Lumi platform.

As the situation is evolving and the Irish Government's guidance may change, shareholders are encouraged to check the website of the Company for any further updates regarding the EGM at
