Dear Shareholder

Annual General Meeting 2021

The Company's Notice of Annual General Meeting and Annual Report and Audited Consolidated Financial Statements for the year ended 31 March 2021 have been published on the Company's website at www.synconaltd.com, in the Shareholder Information section which can be found in the Investors section. To access these documents, you will need to have an application that can read pdf files such as Adobe Reader.

The 2021 Annual General Meeting will be held at 10.30 a.m. on 3 August 2021 at the offices of Citco Fund Services (Guernsey) Limited, Arnold House, St Julian's Avenue, St Peter Port, Guernsey, GY1 3RD.

At the time of writing, although a number of the restrictions in Guernsey arising from the ongoing COVID-19 global pandemic have been relaxed, there is still a requirement for any person arriving on Guernsey to self-isolate for a period of 7 to 21 days, unless certain conditions relating to their place of origin and vaccination status or testing status are met. Accordingly, we anticipate that few shareholders will be able to attend the 2021 Annual General Meeting in person. Shareholders are strongly encouraged to ensure that their votes are counted at the 2021 Annual General Meeting by appointing the chair of the 2021 Annual General Meeting as their proxy in line with the procedures set out below.

The Board remains committed to allowing Shareholders the opportunity to engage with the Board, and if Shareholders have any questions for the Board in advance of the 2021 Annual General Meeting, these can be sent by email to contact@synconaltd.com. The Board will endeavour to answer key themes of these questions on the Company's website as soon as practical.

Voting at the Annual General Meeting

Whether or not you are able to attend the Annual General Meeting, please vote by completing and submitting your Form of Proxy online using Signal Shares at www.signalshares.com or by using the CREST electronic proxy appointment service. This must be received by no later than 48 business hours prior to the time set for the meeting. Alternatively, you can vote by returning the Form of Proxy (enclosed) in accordance with the instructions specified on the form.

To vote online you will need to register using your investor code, which can be found on your share certificate(s). Once you have registered, you will be able to log in and vote. Voting by proxy prior to the meeting does not affect your right to attend the meeting and vote in person, should you so wish.

If you need any help with voting online, please contact the Link Registrars Shareholders Helpline, either:

• by phone on 0371 664 0300 from the UK (calls are charged at the standard geographic rate and will vary by provider. Lines are open between 9.00 a.m. and 5.30 p.m., Monday – Friday),
• by phone on +44 (0) 371 664 0300 from overseas territories, or
• by e-mail at enquiries@linkgroup.co.uk

We would like to thank you for having consented to receive these documents via the Company's website rather than in hard copy form. This will contribute to cost savings for the Company and will minimise unnecessary paper usage.

Yours sincerely

Syncona Limited
