EMC to buy Isilon Systems for $2.25 billion

Purchase price a 29% premium over Isilon's value through Friday; ISLN shares soar

Data storage vendor EMC Corp. will acquire enterprise storage platform company Isilon Systems Inc. for $2.25 billion in cash, or $33.85 per share. The deal was announced Monday morning and is expected to be finalized before the end of the year. Shares of Isilon (NASDAQ: ISLN) soared 7.48, or nearly 30 percent, to $33.77 in Monday's early afternoon trading, while shares of EMC (NYSE: EMC) wed down 10 cents, or 0.46 percent, to 21.62.

The acquisition is the latest in the data storage segment. In September, IBM purchased Netezza for $1.7 billion, while Hewlett-Packard in August outbid Dell to buy 3Par Inc. for $1.5 billion. It's EMC's second data storage move in recent months; the Hopkinton, Mass.-based company in July announced it was purchasing Data Domain. Isilon specializes in "scale-out NAS" (network attached storage), which IDC predicts will be a $6 billion market by 2014. EMC also used the announcement to reaffirm its business outlook for 2010. EMC expects consolidated revenues of $16.9 billion, $0.91 in consolidated GAAP diluted earnings per share, and $1.25 in consolidated non-GAAP diluted earnings per share.
