The full amended text is shown below.

Annual General Meeting 2020 - Change of Arrangements

The Company published its Notice of Annual General Meeting 2020 ('AGM Notice') on 19 March 2020 in respect of its Annual General Meeting ('AGM') to be held on Thursday 14 May 2020 at 11.00am.

Since then, the UK Government has introduced "Stay at Home Measures" and, in compliance with these Measures, the AGM will now take place as a closed meeting, attended by Company Director/Secretary and/or employee shareholders to meet the quorum requirements, and will now be held at Discovery House, 18 Bartley Way, Bartley Wood Business Park, Hook, Hampshire RG27 9XA. It will not be possible for shareholders to attend the meeting in person.

The time and date of the AGM remain unchanged and the formal business to be conducted remains as set out in the AGM Notice, save that, as announced on 2 April 2020, Resolution 3, previously proposed in respect of a final dividend for 2019, will be withdrawn.

Shareholders are strongly encouraged to appoint the Chairman of the Meeting as their proxy. This will enable the Chairman of the Meeting to vote on their behalf, and in accordance with their instructions, at the AGM.

Further information, including arrangements for asking questions, is set out in a letter to shareholders available on the Company's website, at www.serco.com/investors/shareholder-information
