Vestas, the world’s biggest wind turbine maker, saw fourth quarter earnings beat forecasts but trimmed earnings and revenue guidance for 2010.

Earnings before interest and tax (EBIT) rose to €458m ($628m) in October-December from €382m a year earlier.

The result beat an average expectation of a rise to €395m in a Reuters poll of analysts.

Vestas lowered its full-year 2010 revenue forecast to €7bn from a previous range of 7-8 billion and trimmed its EBIT margin guidance for this year to 10-11% from a previous 10-12%.
