Dec. 19 (Bloomberg) -- Electronic Arts Inc., the second- biggest video-game publisher, boosted planned job cuts to 1,000, or 10 percent of its workforce, and said it will consolidate or close at least nine studio and publishing locations.

The changes will yield savings of about $120 million a year and cost as much as $65 million over the next several quarters, the Redwood City, California-based company said today in a statement. Today’s move modifies a 6 percent reduction in staff announced in October.

The maker of “Madden NFL” lowered its full-year revenue and profit forecasts this month because of slow holiday sales in North America and Europe. Electronic Arts has said it will trim its portfolio of game titles to focus on hits.

The company plans to carry out the changes announced today by March 31.

Electronic Arts climbed 73 cents, or 4.3 percent, to $17.49 at 10:31 a.m. New York time in Nasdaq Stock Market composite trading. The shares fell 71 percent this year before today.
