Dynegy

(DYN)

saw its fourth-quarter loss widen and reaffirmed it expects a net loss for 2010.

Dynegy reaffirmed it expects a net loss of $215 million to $140 million in 2010.

Dynergy reported a net loss of $355 million, or 47 cents a share, for the fourth quarter compared with a loss of $7 million, or 1 cent a share, a year ago amid a challenging year for the electricity sector due to significantly lower commodity prices and reduced demand from a weak U.S. economy. The company reported revenue of $441 million vs. $774 million.

Analysts surveyed by Thomson Reuters expected a loss of 13 cents on revenue of $474.7 million.

Fourth-quarter adjusted earnings before interest, taxes, depreciation and amortization was $105 million, compared with $133 million a year earlier.

The company reaffirmed it expects 2010 adjusted EBITDA of $425 million to $550 million.
