Rackable Systems, Inc. today announced its agreement to acquire substantially all the assets of Silicon Graphics, Inc. (SGI) for approximately $25 million in cash, subject to adjustment in certain circumstances, plus the assumption of certain liabilities associated with the acquired assets.

The combined businesses will provide customers with market leading hardware and software technology within large-scale x86 cluster computing, HPC, Internet, Cloud Computing, large-scale data storage environments and visualization platforms across many verticals and geographies. This combination is also expected to result in a stronger global services organization; reaching commercial, government and scientific sectors on a worldwide basis.

“The combined company will be positioned to solve the most demanding business and technology challenges our customers confront today,” said Mark J. Barrenechea, president and CEO of Rackable Systems. “In addition, this combination gives us the potential for significant operational synergies, a strong balance sheet, and positions the combined company for long-term growth and profitability.”

“We have been working very hard to strengthen our company, and today, we’ve taken another big step in that direction,” stated Robert “Bo” Ewald, CEO of Silicon Graphics. “This transaction represents a compelling opportunity for Silicon Graphics’ customers, partners and employees, who can all benefit from the emerging stronger company with better technologies, products and markets reach.”

Barrenechea added, “Together, we believe we will be a much stronger entity with great products and people offering a compelling proposition to compete more effectively in, and across, our collective markets.”

Rackable has signed an Asset Purchase Agreement to acquire substantially all the assets of SGI, and to assume certain liabilities relating to the assets, pursuant to Chapter 11 of the U.S. Bankruptcy Code, under which SGI filed its petition in New York on April 1, 2009. Completion of the transaction is subject to a number of closing conditions, including the approval of the Bankruptcy Court, and other uncertainties. Subject to such conditions and uncertainties, the transaction is expected to close within approximately 60 days. It is expected that SGI’s business operations will continue during the pre-closing period. SGI’s international operations would be part of the sale, but would not be part of the bankruptcy process.

Rackable also announced today that it had suspended its previously announced program including the repurchase of up to $40 million of the company’s stock.
