Rupert Soames to step down as Group Chief Executive of Aggreko

Aggreko plc announces that, after 11 very successful years as Group Chief Executive, Rupert Soames has tendered his resignation from the Group to enable him to take up a new role as CEO of Serco Group plc. He will leave Aggreko after the Annual General Meeting on 24 April 2014.

The Board has commenced a process to identify a permanent successor and has appointed Angus Cockburn, currently Chief Financial Officer, as Interim CEO from 24 April and Carole Cran, currently Director of Group Finance, as Interim CFO.

Rupert Soames said: "I have loved every minute of my time with Aggreko. Our customers, the essential nature of our services and above all our people make it an outstanding company and I am proud to have played a part in its successful growth over the past 11 years. But there comes a time when all CEOs need to move on and now, with a new five year strategy in place and an exceptionally strong executive team running the business, that time has come. Aggreko is a great company with great people and I wish Angus and the team every success."

Ken Hanna, Group Chairman, said: "Rupert has been an excellent CEO for Aggreko and the Group has achieved an enormous amount during his tenure. We will miss him but understand his desire to seek fresh challenges elsewhere. We are delighted that Angus has agreed to become interim CEO whilst we identify a permanent CEO, from strong internal and external candidates. Angus has the support of an extremely able interim CFO in Carole and an excellent management team, who will continue to drive the business forward."

The Group will announce its 2013 Results on Thursday 6 March.
