GSI Technology Updates Outlook Regarding Second-Quarter Fiscal 2012 Revenues

Second-Quarter Conference Call Scheduled

SANTA CLARA, Calif.--October 13, 2011--GSI Technology, Inc. (Nasdaq: GSIT) announced today, that, on the basis of preliminary financial results, the Company expects to report net revenues of approximately $20.8 million for its second fiscal quarter ended September 30, 2011. These estimated results compare to guidance of $22.8 million to $23.8 million that the Company provided early in the second quarter. GSI also reported that direct and indirect sales to its largest customer, Cisco Systems, are expected to be approximately $7.9 million, compared to $9.6 million in the previous quarter, and that softness in demand from Asian OEM customers also contributed to weaker-than-expected second-quarter sales.

The Company cautioned that these results are preliminary and subject to change. The Company expects to release its second-quarter financial results at the market close on Thursday, October 27, 2011. Management will also conduct a conference call to review the Company’s financial results and its current business outlook.
