(Reuters) - Sony Corp. said it was delaying the official submission of its third-quarter results due to the massive cyberattack on Sony Pictures Entertainment, which debilitated network systems at the Hollywood studio.

Sony said it will still hold a news conference on Feb. 4, the originally scheduled date of its results announcement, to give updated financial forecasts for the quarter.

But the company said most financial and accounting applications at Sony Pictures will not be working until early February, and that it has asked financial regulators to extend the filing of its report to March 31 from Feb. 16.
