SST Reports First Quarter 2006 Financial Results

SUNNYVALE, Calif., April 27, 2006 — SST (Silicon Storage Technology, Inc.) (NASDAQ: SSTI), a leader in flash memory technology, today announced financial results for the quarter ended March 31, 2006.

Net revenues for the first quarter were $110.5 million, compared with $133.2 million in the fourth quarter of 2005 and $86.3 million in the first quarter of 2005.

Net income for the first quarter of 2006 was $11.3 million, or $0.11 per share, based on approximately 104.7 million diluted shares outstanding. This result includes a pre-tax net gain from investment activities in the first quarter of 2006 of approximately $8.7 million. By comparison, SST recorded a net income of $8.4 million, or $0.08 per share, on approximately 104.8 million diluted shares outstanding in the fourth quarter of 2005. For the first quarter of 2005, the company reported a net loss of $13.9 million, or a loss of $0.14 per share, based on approximately 97.8 million diluted shares outstanding.

SST became subject to FAS 123R this quarter and recorded compensation charges of $1.9 million associated with its stock option plans.

SST finished the first quarter of 2006 with $107.3 million in cash, cash equivalents and short-term

investments, an increase of $28.9 million from the prior quarter.

Management Qualitative Comments

“While we entered the first quarter with strong bookings, our customers began canceling or pushing out orders after the lunar New Year in January,” said Bing Yeh, president and CEO. “The slowdown was the result of weaker than expected demand in a number of key applications, including desktop PCs, printers, graphics cards, optical drives and MP3 players. We also experienced fab issues with one of our wafer foundries and capacity constraints for certain package types at one of our backend suppliers. As a result, unit shipments in the first quarter decreased 20 percent compared with the prior quarter. However, these factors affected more of our lower margin products, allowing us to achieve higher than expected gross margin results.

“Despite this weakening demand, we experienced a relatively stable pricing environment in the first quarter. Our blended ASP increased three percent from the previous quarter due to a larger percentage of higher priced products in our unit shipments. Excluding the product mix, selling prices increased by less than half percent. Unlike the NAND flash market where there is additional capacity coming online during a time of seasonal oversupply, the low density NOR flash market, in which we participate, is not increasing capacity. While there continues to be competitive pressures, we expect prices in the NOR flash market will show only modest decreases for the current quarter.

“Looking ahead, we are focused on several goals: First, we expect to continue the transition of our current products to smaller geometries. This should allow us to further lower our manufacturing costs and to make our products even more competitive in the marketplace. Second, we expect to continue to bring innovative memory and non-memory products to market. These products will allow us to expand into high growth areas such as mobile phones and broadband networking areas where SST has a very small market presence today. Finally, we expect to continue the expansion of our licensing business with more advanced technologies to maintain SuperFlash as the technology-of-choice for embedded flash applications. As always, we will continue our policy of tight expense control in order to maximize the positive effects of these goals to our bottom line. While market demand is expected to remain weak through the first half of 2006, we believe we are well-positioned for growth in the second half of the year with proven technology, strong licensing relationships and a healthy balance sheet.”

Second Quarter 2006 Outlook

SST expects its second quarter revenues to be between $95 million and $110 million. Gross margin is expected to be between 26 and 29 percent, subject to the risk of changing market conditions. Research and development expenses are expected to be approximately $15.4 million and total operating expenses are expected to be approximately $28.7 million, of which stock option expense is expected to be approximately $1.9 million. Therefore, fully diluted earnings/loss per share is expected to be between ($0.03) and $0.03.
