Coronavirus (COVID-19) and its impact on the AGM

Our preference had been to welcome shareholders in person to our AGM this year, particularly given the constraints we faced in 2020 due to COVID-19. However, at the time of posting this notice, we are still in a national lockdown and, as a result, are therefore proposing to hold the meeting with the minimum attendance required to form a quorum. Shareholders will not be permitted to attend the AGM in person but can be represented by the Chairman of the meeting acting as their proxy.

Given the constantly evolving nature of the situation, should circumstances change before the date of the meeting, we want to ensure that we are able to adapt arrangements and welcome shareholders to the AGM, within safety constraints and in accordance with government guidelines. Should we consider that it has become possible to do so, we will open the meeting to attendance from all shareholders and provide notification of this change through a Regulatory Information Service (RIS) announcement as early as is possible before the date of the meeting. Please refer to the Shareholder information section of our website at www.ibstockplc.co.uk for any updates to this position.

To increase the level of transparency with shareholders, and encourage engagement, the Company will provide access for individuals wishing to view a webcast of the AGM online and further information regarding this service will be published on our website. In addition, any shareholder who wishes to ask a question can do so in advance of the meeting by emailing company.secretariat@ibstock.co.uk prior to the start of the AGM. We endeavour to answer as many questions as possible, prior to, and during the AGM and will respond by email if we are unable to answer your question during, or prior to, the meeting.

Proxies

Given the uncertainty around whether shareholders will be able to attend the AGM, we recommend that all shareholders submit a proxy vote in advance of the meeting. Details on how to do so by post, online or through CREST are set out in the Notice of the Meeting. Given the current restrictions on attendance, shareholders are urged to appoint the Chairman of the meeting as their proxy to ensure their vote will be counted (rather than a named person who will not be permitted to attend the meeting).

Action to be taken

Your vote is important to us and we encourage you to submit your proxy vote in one of the following ways:

• Submit your proxy vote electronically by accessing the shareholder portal at www.signalshares.com, logging in and selecting the 'Vote Online Now' link. You will require your username and password in order to log in and vote; or
• Request and complete a hard copy proxy form from our Registrars Link Asset Services by emailing enquiries@linkgroup.co.uk or by post at Link Group, 10th Floor, Wellington Square, Leeds LS1 4DL; or
• In the case of CREST members, you can appoint your proxy through the CREST proxy appointment service as detailed in note 6 on page 7 of the Notice of Meeting.

Please note that the deadline for the receipt by our Registrars of all proxy appointments is 11:00 a.m. on Tuesday 20 April 2021 (48 hours before the start of the meeting. In view of current government restrictions on public gatherings, we urge you to appoint the Chairman of the meeting as your proxy, to ensure your vote will be counted.

The results of the AGM will be announced through an RIS announcement and on the Company website, as soon as practicable after the AGM.
