Ahead of entering a close period in respect of the year ending 31 December 2013, Aggreko plc is giving the following update on trading. Preliminary results will be announced on Thursday, 6 March 2014.

Trading Update

On an underlying basis we expect that Group revenues for 2013 will be around 3% higher and trading profit will be at similar levels to the prior year. "Underlying" excludes the impact of the London Olympics, the Poit Energia acquisition, pass-through fuel and currency movements. Reported Group revenues for the year are expected to be around £1.57 billion, similar to last year, and profit before tax and amortisation is expected to be at least £335 million.

Underlying revenues for the year are expected to grow by around 8% in EMEA and in the Americas by around 7%; APAC is expected to be around 12% lower than last year, principally due to our TEPCO contracts finishing in Japan and some off hires in Indonesia.

Revenues in our Power Projects business for the year are expected to be around 2% lower than last year on both an underlying and reported basis. As anticipated, underlying trading margins for the year are likely to be down on prior year at around 30%. Order intake for the year to date is over 700 MW. We have signed a six-month 80 MW diesel contract in Panama, under which we will provide power as a licenced generator to the Panamanian wholesale electricity market; this is, we believe, the first time that a temporary power supplier has entered a country's wholesale electricity market competing with permanent power generators. We have also signed a number of smaller contracts in the quarter, including two HFO contracts, and we have recently received a further three-month extension on our 150 MW of diesel contracts in Japan to the end of the first quarter of 2014.

The Local business is on track to deliver a good full year performance with underlying revenues expected to be around 6% higher than the prior year and underlying margins expected to be slightly ahead of last year. Reported revenues are expected to be flat on the prior year, reflecting the impact of the London Olympics. We are delighted to report that we have been chosen as the supplier of temporary power for the 2014 FIFA World Cup and the Glasgow 2014 Commonwealth Games.

We now expect to take delivery of about £15 million of ancillary fleet items in early 2014 rather than late 2013. As a result we now expect fleet capital expenditure to be around £215 million in 2013 and in the region of £155 million in the first half of 2014.

Financial position

Strong cash generation, mainly driven by lower capital expenditure, is expected to reduce net debt by around £200 million over the prior year, with resulting net debt likely to be below £400 million at the year end.
