INTERIM MANAGEMENT STATEMENT

Strong performance in the third quarter; outlook for the year increased

Aggreko plc, the world leader in the supply of temporary power and temperature control, is today issuing its Interim Management Statement covering the period from 1 July 2011 to date.

Trading

Aggreko has delivered a strong performance in the third quarter. On an underlying basis (in constant currency and excluding the one-off impact of the FIFA World Cup as well as pass-through fuel), revenue grew by 22%. Headline revenue increased by 13%.

Revenue in our International Power Projects business in constant currency and excluding pass-through fuel grew by 26% in the third quarter. Headline revenue increased by 20%. Order intake in the year to date has been 944MW with 210MW added in the quarter, including an additional 60MW in Kenya and 47MW in Brazil. Capacity on hire at the end of the quarter was 21% ahead of the prior year. Good progress has been made resolving the three overdue debtors highlighted at the time of the interims and, as a result, there has been a partial write back of the provisions taken in the first half and we now expect that the trading margin in IPP for the year as a whole will be a little higher than the prior year.

In the Local business, underlying revenue (in constant currency and excluding the one-off impact of the FIFA World Cup) grew by 20% in the third quarter. Headline revenue increased by 8%. Revenue in North America grew by 10%, and in Europe & Middle East by 20%; the Middle East business has recovered strongly and we have recently signed our first sizeable contract with an industrial company in Iraq, which we see as being an important market in the future. On an underlying basis revenue in Aggreko International's Local business grew 41%, while on a headline basis revenue was down 8% reflecting the impact of the FIFA World Cup in the prior year. We expect underlying trading margin in the Local business for the year as a whole to be similar to the prior year.

Financial position

Net debt at £424 million has increased by £167 million in the three months to 30 September 2011, mainly as a result of the return of capital to shareholders of £148 million that took place in July 2011.

Outlook

Although the prospects for the global economy remain uncertain, the strength of our recent trading performance, and our view of the prospects for the fourth quarter, mean that we now believe that pre tax profits for the year will be at least £320 million. This represents underlying growth in profits for the year of over 24%.

Rupert Soames, Chief Executive, said, "I am delighted to see both our businesses producing underlying growth of 20% or more, and we have good momentum going into the fourth quarter."

There will be a conference call for analysts and investors at 8am. For dial-in details, please contact Sian Stanley on 020 7379 5151 or [email protected].
