Electronic Arts, the world’s second-largest video-game publisher, tumbled in extended trading yesterday after its full-year forecast trailed some analysts’ estimates.

Fiscal 2011 profit, excluding some items, will be 50 cents a share to 70 cents a share, the Redwood City, Calif.-based company said yesterday in a statement.

The “Madden NFL” maker, which has cut more than 2,500 jobs since 2008, missed its last two annual profit targets after disappointing holiday sales. The company aims to boost profit by releasing fewer titles, cutting costs and expanding online and mobile offerings.

Its third-quarter net loss narrowed to $82 million, or 25 cents a share, from a loss of $641 million, or $2 a share, a year earlier. Shares fell $1.48, or 8.5 percent, to $16.01.
