SST Reports Third Quarter 2003 Financial Results

Unit Shipments Up 24 Percent Sequentially

SUNNYVALE, Calif., Oct. 22, 2003 -- SST (Silicon Storage Technology, Inc.) (NASDAQ: SSTI),a leader in flash memory technology, today announced financial results for the third quarter ended Sept. 30, 2003.

Net revenues for the third quarter were $73.9 million, compared with $64.2 million in the second quarter of 2003 and with $67.8 million in the third quarter a year ago.

The company took a charge in the third quarter of $36.5 million due to the increased probability of a loss in the litigation with Atmel. This combined with other items resulted in a GAAP loss before provision for income taxes in the third quarter of $36.1 million. This compares with a GAAP loss before taxes of $3.2 million for the second quarter of 2003, and a GAAP loss before taxes of $8.9 million in the third quarter of 2002. Excluding the charge, SST would have had a non-GAAP profit before provision for income taxes in the third quarter of $388,000. A reconciliation of the GAAP results to the non-GAAP results appears in the financial statement portion of this release.

The company completed the implementation of its international tax structure this past quarter. In addition under GAAP, as the company had cumulative losses for the past three years, SST was required to record a valuation allowance against its deferred tax asset of $45.3 million during the third quarter. The combined impact of these two items was a tax expense in the third quarter of $22.9 million. This compares with a tax expense of $1.4 million in the second quarter of 2003 and with a tax benefit of $4.1 million in the third quarter of 2002. In the future, the company will only record a tax expense as a result of foreign

withholdings and other items until the valuation allowance against the deferred tax asset is more likely than not to be realized.

Net loss for the third quarter was $59.0 million, or a loss of $0.62 per share, based on approximately 95.0 million shares outstanding. This compares with a net loss of $4.6 million, or a loss of $0.05 per share on approximately 94.5 million shares outstanding in the second quarter of 2003, and with a net loss of $4.8 million, or a loss of $0.05 per share on 93.0 million shares outstanding in the third quarter of 2002.

"We are pleased to report that the demand for our products has increased sharply since the beginning of the third quarter," said Bing Yeh, president and CEO. "We believe the long-awaited industry upturn has finally arrived. Booking activities have been very strong across all application segments, led by the digital consumer and Internet computing segments. At more than one million units a day, unit shipments for the quarter set a new record, up 15 percent from the peak quarter in 2000 and up 24 percent from the second quarter. Lead times for all products have been stretching out and certain high volume products with 2M, 4M, 8M and 16Mbit densities are on allocation.

"The positive impact on the third quarter revenue due to the increased units shipped was partially offset by slightly decreased selling prices. However, we believe that the pricing environment has changed substantially from prior quarters. We expect to see improvement in ASPs in future quarters as a result of both supply shortage and as our product mix moves toward higher-densities.

"We continued our efforts in improving our manufacturing cost for our products during the third quarter. Substantially all of our 2Mbit to 8Mbit products have been transitioned to 0.25 micron process from 0.33 micron process. The 16Mbit products are being transitioned directly from 0.33 micron to 0.18 micron process. We expect to see more of the financial impact from these transitions in the coming quarters. As for new products, we have begun the production shipment of 32Mbit products and have verified the design of a 64Mbit product. These new products are based on the 0.18 micron second-generation SuperFlash technology. We believe the shipment of these higher density products will have major contribution to our expected revenue growth in 2004.

"During the third quarter, we also signed two important licensing agreements. In July we entered into an agreement with Malaysia's pure-play wafer foundry, 1st Silicon, to license SST's 0.25 micron SuperFlash technology to manufacture embedded flash products for its foundry customers.  The embedded flash is the first of several new technologies 1st Silicon will be adopting in order to differentiate itself from peer foundries and to add value to its customers.

"In September we signed an agreement with Toshiba to license SST's 0.5 micron SuperFlash technology for the manufacture of 8bit and 16bit microcontroller products with embedded flash. The agreement underscores the success of SST's high-reliability, high-performance and cost-effective SuperFlash technology as the technology-of-choice for embedded applications.

"As the broad-based industry recovery begins to unfold, we continue our focus on returning the company to profitability while expanding our market share. We believe the efforts we have made during the past semiconductor recession: our technology advancement, our new products, our additional wafer- foundry partnerships, our enlarged licensee base, our worldwide customer support infrastructure and our expanded global presence will pay off handsomely as the improvement of the macro economy continues."

Fourth Quarter 2003 Outlook

The company believes that its fourth quarter revenues will increase 15 percent to 20 percent over the third quarter, assuming no drastic changes occur in the U.S. and international economies. Gross margin is expected to be between 26 and 29 percent. The company's gross margin projection takes into consideration the risks associated with the company's technology and product transition including yield and customer qualification timing. Primarily due to foreign withholding taxes the company expects to have charges for income tax related expenses of between $1.5 million and $2.0 million. With these revenue and expense levels, SST expects to achieve earnings per share of between $0.01 and $0.03 in the fourth quarter.

Non-GAAP Financial Measures

A non-GAAP financial measure is a numerical measure of the company's performance or financial position that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The company believes that the additional non-GAAP measure used in this press release is useful to investors for the performance of financial analysis. The Company's management used this measure internally to evaluate the company's operating performance during the third quarter and for planning and forecasting of its future periods. Non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures. Other companies may use different non-GAAP measures and presentation of results.
