(Reuters) - Norton antivirus software maker Symantec Corp (NASDAQ:SYMC) said it would sell its data storage business, Veritas, for $8 billion in cash to a group including Carlyle Group (NASDAQ:CG) LP and Singapore's sovereign wealth fund GIC.
Shares of Symantec, which also reported lower-than-expected quarterly revenue and profit, rose about 2.5 percent in premarket trading on Tuesday.
Symantec bought Veritas for $13.5 billion in 2005 to add data storage and management to its enterprise offerings.
Revenue from Symantec's information management business, which accounts for nearly 40 percent of the company's total revenue, fell 10 percent in the first quarter.
The software maker said it expected about $6.3 billion in net cash proceeds from the sale, expected to close by Jan. 1.
Reuters reported earlier on Tuesday that Symantec would sell Veritas to Carlyle.
Symantec, whose software comes bundled with PCs, posted its fourth straight quarter of falling revenue on Tuesday, mainly due to sliding PC sales.
Revenue from its consumer security business fell 19 percent in the quarter ended July 3, while enterprise security revenue dropped 13 percent.
The company also forecast current-quarter profit and revenue below analysts' expectations.
Symantec forecast an adjusted profit of 40-43 cents per share and revenue of $1.49 billion-$1.53 billion for the second quarter.
Analysts on average were expecting earnings of 45 cents per share and revenue of $1.54 billion, according to Thomson Reuters I/B/E/S.
Symantec's net income fell to $117 million, or 17 cents per share, in the first quarter from $237 million, or 34 cents per share, a year earlier.
Excluding items, the company earned 40 cents per share.
Revenue fell 13.6 percent to $1.5 billion.
Analysts on an average had expected a profit of 43 cents per share and revenue of $1.53 billion.
