, reported a fourth-quarter net loss of $1.86 billion, or $8.25 a share, compared with a net profit of $106 million, or 45 cents a share for the same period a year before.

SanDisk's annual revenue dropped from $1.25 billion to $863.9 million. The Milpitas, Calif., company got smacked with $1.91 billion in one-time expenses, including $1.02 billion for a combined pre-tax goodwill and intangible asset impairment charge.

Analysts had expected the company to post a loss of 60 cents a share on revenue of about $767 million, according to Thomson Reuters.

"Despite a very difficult pricing environment, macroeconomic turmoil and the impact on consumer purchasing, we delivered sequential revenue growth in the fourth quarter," said SanDisk CEO Eli Harari in a statement. "However, we are very disappointed with our fourth-quarter bottom line results, which included significant asset impairment and inventory related charges."

SanDisk shares closed the regular trading session down 1.3% to $11.28 but were rising more than 6% in after-hours trading.
