COPENHAGEN, Feb 11 (Reuters) - Vestas <VWS.CO>, the world's biggest wind turbines maker, posted a better than expected 51 percent rise in 2008 operating profit, but its shares gave up early gains over uncertainty concerning its 2009 outlook.
Vestas is riding a surge in demand for renewable energy, although Chief Executive Ditlev Engel said some customers are struggling to secure financing for new projects because of the global financial crisis.
That crisis, as well as the uncertainty around the expansion of subsidies in the United States, its biggest national market, could prompt the company to cut its planned 2009 spending and even trim some jobs.
"If the world does not improve, we will have to look to cut jobs at Vestas," Engel told analysts in New York. "This will be the last resort we will go to if necessary."
Earnings before interest and taxes (EBIT) rose to 668 million euros ($864 million) last year, from 443 million in 2007, compared with an average estimate given in a Reuters poll of analysts of 619 million.
Sales rose 24 percent to 6.04 billion euros.
Vestas repeated its forecast for 2009 of sales of 7.2 billion euros and an EBIT margin of 11 percent to 13 percent, but said expectations for investments of 1.2 billion euros were subject to an improvement in the order intake in the first four months this year.
"We believe this will be challenging for Vestas, as the company's expectations of strong improvements in order intake with the new U.S. administration will be more feasible from 2010," Standard & Poor's Equity Research said in a note.
The firm raised its recommendation on the back of the results to "buy" from "sell".
Vestas shares were up as much as 10 percent, but settled and gave up gains to finish 0.4 percent up at 287 crowns, as Engel answered a number of questions on the certainty of the company's 2009.
Engel said he believed a number of U.S. customers were sitting on the fence waiting for the final results of the negotiations on the country's economic stimulus package before placing orders.
"What we want to highlight is that if the financial and banking sector doesn't start operating more on a normal scale then we will have to relate to that and to what degree and how much on all areas of the profit and loss statement we have to see in the next few months," Engel said.
President Barack Obama, who has said the package is essential to avert a deeper recession, wants to have a bill to sign into law by this weekend.
Engel said the Jutland-based group had not yet experienced cancellations or postponements in its order backlog but said new market players, especially from China, were sharpening competition.
"I don't think his answers were any change to what you could already read between the lines in the results statement and how important the U.S. stimulus package is to orders this year," said Jyske Bank analyst Christian Nagstrup.
Vestas, which competes with Spain's Gamesa <GAM.MC>, India's Suzlon Energy <SUZL.BO> and units of global power generation giants Siemens <SIEGn.DE> and General Electric <GE.N>, had an order backlog at the end of the year valued at 5.2 billion euros, from 4.8 billion at end-2007.
That figure compared with 6.5 billion euros at the end of the third quarter. (Additional reporting by Matt Daily in New York, Editing by Greg Mahlich and Andrew Macdonald)
