Total gross margin as a percent of revenues for the fourth quarter of fiscal 2008 is expected to be in the range of 44 to 45 percent.

Sun anticipates reporting GAAP net income per diluted share for the fourth quarter of fiscal 2008 in the range of $0.05 to $0.15. GAAP net income per diluted share includes a restructuring charge of approximately $100 million. On a non-GAAP basis, Sun expects to report net income per diluted share in the range of $0.25 to $0.35. Non-GAAP net income per diluted share excludes purchased in-process research and development, amortization of acquisition-related intangibles, stock-based compensation expense, restructuring charges and related impairment of long-lived assets, gain or loss on equity investments, settlement income and the related income tax effects of non-GAAP exclusions.

“In these difficult economic times, we continue to see customers across the world look to open software and hardware as a source of savings, and feel Sun is well positioned with our most robust line ever of server, storage, software and service offerings,” said Jonathan Schwartz, CEO of Sun Microsystems.
