Highlights include:

- Trading in the first quarter has been in line with our expectations with underlying(1) Group revenues growing by 8% in the three months to 31 March 2013.

- Local business has had a very strong start to the year, with 17% more power on rent than a year ago. Power Projects improved order intake, with notable contracts including 122 MW of cross-border power to Namibia and Mozambique and a new heavy fuel oil (HFO) contract for 56 MW in the Caribbean.

- Expectations for the year remain unchanged from previous guidance.

Trading

Trading in the first quarter has been in line with our expectations, with underlying Group revenues growing by 8% in the three months to 31 March 2013; "underlying" excludes revenues from the London Olympics, the Poit Energia acquisition, pass-through fuel and currency movements. On a reported basis, revenues increased by 7% and trading margins were in line with the same period last year.

The Americas region grew revenues by 9% on an underlying basis; Asia, Pacific and Australia (APAC) was 1% ahead of last year on an underlying basis; and Europe, Middle East and Africa (EMEA) grew 13% on an underlying basis.

Power Projects revenues were 5% ahead of last year on an underlying basis. Reported revenues were down 3%, as a result of lower levels of pass-through fuel; trading margins were at similar levels. Quarter one order intake of 260 MW was stronger than quarter four 2012 and includes our recently announced contract to provide 122 MW of cross-border power to Namibia and Mozambique, as well as our first large order for our new heavy fuel oil (HFO) engine for 56 MW in the Caribbean.

The Local business has had a very strong start to the year, with 17% more power on rent than a year ago. Encouragingly, growth in the Local business has been broadly spread, with most areas other than Europe showing healthy year-on-year increases in MW on hire. Revenues in the first quarter were up 10% on an underlying basis; on a reported basis revenues were up 16% and trading margins were similar to last year.

Financial position

Net debt at £597 million has increased by £4 million in the three months to 31 March 2013. This compares to net debt of £428 million at 31 March 2012; of the £169 million year-on-year increase, £136 million was accounted for by the Poit Energia acquisition with the balance reflecting higher working capital requirements.

Outlook

The pattern of trading is largely unchanged from that described at our Results Presentation on 7 March; the Local business has made a strong start to the year and trading in Power Projects remains subdued, although the prospect pipeline has improved.

We now expect to spend around £130 million in the first half on fleet capital expenditure, and around £260 million for the year as a whole, although as always we will increase or decrease our rate of investment depending on market conditions.

Overall, our expectations for the year remain unchanged from previous guidance.

A conference call for investors and analysts will take place today at 0830 BST. To join the call please contact Maitland on the number below for the dial in details.
