INTERIM MANAGEMENT STATEMENT

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 2010 to date.

Trading

Group revenues in the three months to 30 September 2010 were 30% higher than in the same period in 2009; on a constant currency basis, and excluding pass-through fuel, revenues increased by 24%, and trading margins were at similar levels to last year.

Revenues in our International Power Projects business, in constant currency and excluding pass-through fuel, grew by about 11% with average MW on rent in the quarter around 8% up on the prior year. As anticipated, the third quarter saw a continuation of the high off-hire rates seen in the second quarter; however, we expect that the rate of off-hires will return to more normal levels in the fourth quarter, and that the megawatts on hire at the end of the quarter will show good year-on-year progress. Major orders in the period included 60MW in Cameroon, 80MW in Indonesia, 50MW in India and 20MW in Martinique. As announced on 25 October, we are also in the final stages of formalizing a three-year contract for 150MW of gas-powered generation in Bangladesh, which over its life is expected to be worth over $180 million. Margins in the third quarter were similar to those seen in the first half.

Conditions in the Local business continue to improve with revenues in constant currency growing by 34% as a result of increases in both utilisation and price. Excluding the FIFA World Cup, the Local business grew 22% on a constant currency basis. Performance in North America was very strong and revenues in the quarter grew by 36%; after a poor year in 2009, high temperatures drove strong demand for temperature control and demand across all products was strong in the manufacturing and petrochemical sectors. Revenues in Europe and Middle East grew by 11% with Continental Europe performing particularly well; as in North America, temperature control recovered sharply against a weak prior year. Revenues in Aggreko International's Local business were up 90% largely due to the FIFA World Cup; excluding the World Cup, revenues were up 17%, with every business delivering good growth. Margins across the Local businesses improved on the same period in the prior year.

Financial position

Net debt at £155 million has decreased by £4 million in the three months from 30 June 2010 and is £72 million lower than at 30 September 2009.

Outlook

Year-on-year comparisons for the fourth quarter need to take account of the 53rd week of trading in 2009 and the Vancouver Olympics.

We expect the Local business to make further strong progress in the fourth quarter, and all three regions are performing ahead of our expectations. Aggreko International's Local business in particular will be helped by the recent award of the contract for the Asian Games in China.

We expect that our International Power Projects business will continue to perform in line with our expectations. The recent strong order intake, combined with a sharp reduction in the rate of off-hires, will give us good year-on-year growth in MW on hire by the end of the year.

At a Group level, the strength of our recent trading performance and expectations for the fourth quarter mean that we now believe that pre tax profits for the year will be around £300 million which is above the consensus of current analysts' expectations(1).

There will be a conference call for analysts and investors at 09.00am. For dial-in details, please contact Sian Stanley on 020 7379 5151 or sstanley@maitland.co.uk.
