COVID-19 and the Annual General Meeting

Since the posting of the Notice of the 2020 Annual General Meeting (AGM), to take place on Thursday 23 April 2020 at 11.00am, the UK and Scottish Governments have announced compulsory measures (the 'Stay at Home Measures') prohibiting, among other things, public gatherings of more than two people. As a result, the Board has decided that it is no longer practical or desirable to hold the Company's AGM at 200 SVS, 200 St Vincent Street, Glasgow G2 5RQ, as previously notified in the Notice of Meeting.

In the circumstances, the AGM will be held on the same date and at the same time, but at the offices of the company at 5th Floor, Asticus, 21 Palmer Street, London SW1H OAD, and will be restricted to the formal business of the AGM with no corporate presentation or questions. If the Stay at Home Measures remain in place for England, the meeting will be restricted to two attendees (for example the Chairman and Chief Executive Officer) both of whom will be eligible to count for the purposes of forming a quorum, in order to comply with Government measures on gatherings that are 'essential for work purposes'. Other shareholders should not seek to attend the AGM in person and will not be admitted.

The Board encourages all shareholders to exercise their vote by appointing the Chairman of the meeting as their proxy and providing voting instructions in advance of the AGM, in accordance with the instructions explained in the Notice of AGM. At the AGM, resolutions will be put to a vote on a poll, rather than on a show of hands. This will result in a more accurate reflection of the views of shareholders and ensure that your proxy votes are recognised.

You can appoint a proxy with voting instructions using the shareholder portal at https://shares.aggreko.com or by returning a completed proxy card in accordance with the instructions set out in the Notice of AGM. CREST members may use the CREST electronic proxy appointment service, institutional investors may also use the Proximity Platform as detailed in the Notice of Meeting. Please note that the deadline for submitting proxy voting instructions is 11.00 am on Tuesday 21 April 2020.

Shareholders wishing to raise any questions relating to the business of the AGM may do so by submitting them to Aggreko's Investor Relations team ahead of the meeting at [email protected]. The Company will publish an appropriate summary of responses on its website as soon as possible after the meeting.

Please note that as announced on 23 March, the Board has withdrawn its recommendation of the final dividend for the year ended 31 December 2019, and accordingly that Resolution 3 will be withdrawn at the AGM.

The situation in relation to COVID-19 continues to develop. The Board encourages shareholders to monitor the Company's website and regulatory news services for any updates in relation to the AGM.
