COVID-19 – AGM Arrangements

Due to the ongoing UK Government "stay at home measures" which currently include a prevention of public gatherings of more than two people, some changes will need to be made to the way the AGM is held this year.

The AGM will now be run as a closed meeting and shareholders will not be able to attend it in person as the Company’s articles of association do not permit hybrid or virtual meetings to be held. Shareholders attempting to attend the AGM will not be permitted entry to comply with the law and to ensure the safety of the meeting. The Directors hope that you understand we are taking these steps to protect shareholders and the attending Directors.

Appropriate arrangements have been made such that the legal requirements to hold the meeting will be satisfied with the minimum necessary quorum of two shareholders, being the chairman and non-executive director, present in person.

Shareholders are strongly encouraged to vote by proxy on the resolutions contained in the AGM Notice and to appoint the chairman as their proxy. For full details on how to register a vote by proxy, please refer to the AGM Notice. If a person other than the chairman is appointed as a proxy then they will not be permitted entry to the meeting and will not therefore be allowed to participate in it on the shareholder’s behalf. The business at the AGM will be confined to the formal business section only, with no wider presentations on business performance or Q and A. If any shareholder has a question they would like to pose to the Directors, these should be submitted to the chairman via .

The Board believes that the resolutions contained in the AGM Notice continue to be in the best interests of the Company and its shareholders as a whole and recommends that shareholders vote in favour of them.

The Board would like to take this opportunity to thank all shareholders for their continued support and understanding in these exceptional circumstances and wish them well during this time.

THE DIRECTORS OF CLEANTECH BUILDING MATERIALS PLC ACCEPT RESPONSIBILITY FOR THE CONTENTS OF THIS ANNOUNCEMENT
