THIS DOCUMENT IS IMPORTANT AND REQUIRES YOUR IMMEDIATE ATTENTION.

When considering what action you should take, you are recommended to seek your own personal advice immediately from your stockbroker, bank manager, solicitor, accountant or other professional adviser duly authorised under the Financial Services and Markets Act 2000 (as amended).

Dear Shareholder

I am writing to inform you that the 2021 Annual Report of Kier Group plc (the 'Company') and the Notice of AGM are available online at www.kier.co.uk. The business to be conducted at the AGM is set out in pages 3 and 4 of the Notice of AGM.

AGM arrangements

The Annual General Meeting (the 'AGM' or the 'Meeting') will be held at 10.00 a.m. on Friday, 19 November 2021 at Linklaters LLP, One Silk Street, London EC2Y 8HQ. We currently anticipate that we will be able to hold the AGM in the normal way this year and shareholders will be welcome to attend the AGM in person. However, in light of the potential risks with COVID-19, we will put in place appropriate safety measures in the interests of maintaining the safety of our shareholders, colleagues and AGM support staff, as well as the public. This will include, but not be limited to, wearing face masks when moving around the venue, temperature checks and social distancing. Although the Directors will be attending in person, for safety reasons there will be limited opportunities to interact with them before and after the meeting.

In the event that the AGM arrangements need to change, the Company will issue a further communication via a regulatory information service and on our website at www.kier.co.uk/investors. Shareholders are therefore advised to check the Company's website for any changes to arrangements.
