Sumo Group plc

("Sumo Group" or the "Company")

Notice of AGM and Posting of Annual Report and Accounts

Sumo Group announces the annual report and accounts for the year ended 31 December 2020 and the Notice of Annual General Meeting ("AGM"), to be held at 2pm on 17 June 2021, will shortly be available on the Group's website at www.sumogroupplc.com.

Where applicable, copies of the Annual Report and Accounts and Notice of Annual General Meeting will be posted to shareholders later today.

Format of the AGM

The Board of Directors continues closely to monitor the coronavirus pandemic and our priority at this time remains the health, safety and wellbeing of all of our stakeholders. As part of its monitoring, the Board has noted, in particular, the gradual easing of public health restrictions across England in line with the government's "COVID-19 Response - Spring 2021" roadmap published in February. Based on that roadmap and associated guidance, it is currently anticipated that attendance in person at the meeting will not be unlawful. It is therefore intended that sufficient of the Directors to form a quorum will be present in person at the AGM, observing relevant social distancing guidelines in place on the date of the meeting. However, given ongoing public health considerations, shareholders are strongly encouraged not to attend the meeting in person and to appoint the Chair of the meeting as proxy.

Engagement

The Board recognises the importance of the AGM to shareholders and is keen to ensure engagement in this year's AGM as effectively as practicable. As such a webcast will be accessible for shareholders to view and listen to the AGM remotely. Details are set out in the Notice of the AGM.

Change of circumstances

The coronavirus pandemic is an evolving situation and the arrangements are subject to change, including at short notice, if circumstances and/or public health guidance changes. The Board therefore recommends that you monitor the Company's announcements for any updates, by registering for email alerts on the Company's website at www.sumogroupplc.com/investors-centre/email-alerts/.
