Management Qualitative Comments

“During the first quarter, in addition to seasonality, we experienced some softness in our business as several high-volume customers pushed out shipments of their orders and others have been slow to reengage following our capacity shortage at the end of last year that necessitated our turning away certain opportunities,” said Bing Yeh, president and CEO.  “We do expect to ship to some of those customers in the current quarter but ongoing volatile macroeconomic conditions are prompting us to plan and guide conservatively for our business.  However, despite difficult current market conditions, we are pleased by the growth prospect of our high-ASP product platforms that we have been developing over the past few years.   We are very proud of the acknowledgement that our newest products are receiving from the industry and we believe that they will be a key component of our growth over the next several years.”

Second Quarter 2008 Outlook

SST expects revenues of between $75 million and $85 million, assuming a slowdown in the U.S. and international economies.  Gross margin is expected to be between 25 percent and 28 percent, subject to changing competitive market conditions.  Total operating expenses are expected to be between $29 million and $32 million including non-cash stock-based expense.  Net loss per share for the second quarter of 2008 is expected to be between $0.08 and $0.12.
