(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.
