TAIPEI, Taiwan, Oct. 30, 2008 (GLOBE NEWSWIRE) - Silicon Motion Technology Corporation (Nasdaq:SIMO) (the "Company") today announced its third quarter 2008 financial results. Third quarter net sales decreased 7% quarter-over-quarter to US$45.0 million. GAAP net income increased 313% quarter-over-quarter to US$8.1 million, or US$0.26 per diluted ADS, compared to US$0.06 per diluted ADS in the second quarter of 2008.

Non-GAAP net income, which excludes stock-based compensation, acquisition-related charges, foreign exchange gain or loss, and one-time items, decreased 1% quarter-over-quarter to US$8.7 million, or US$0.27 per diluted ADS, compared to US$0.26 per diluted ADS in the second quarter of 2008.

Commenting on the results, Silicon Motion's President and CEO, Wallace Kou, said:

"The third quarter, as we had previously communicated, was challenging because of weak conditions at end markets globally and many of our customers exited the previous quarter with excess flash card inventory. OEMs however have been aggressively working to reduce their inventory. Because of customer inventory reduction and related rebuilding, as well as strong sales in China, we were able to increase our overall card controller shipments by 12% sequentially. Our total storage controller shipments for the first nine months of this year rose 46% compared to the same period last year.

We believe that while consumer markets have been negatively impacted by macroeconomic issues, sales of NAND flash based storage devices, including memory cards, USB flash drives, SSDs, and embedded flash are showing some signs of resiliency. We believe there is still elasticity of demand, though perhaps less than during better times. Prices for flash components have been falling rapidly and in turn retail prices for storage devices using flash have also seen decreases. The falling prices have driven volume and increased adoption of NAND flash by OEMs, even as consumer confidence remains weak.

Market conditions are tough, but we continue to believe that the Company is well positioned because of our strong flash controller IP, market leadership, and investments to support growth applications whether relating to memory cards, SSDs, or mobile TV. Furthermore, the NAND flash industry is beginning the transition to sub-50 nm products. We have already started sampling our controllers for 34nm and other next generation flash. These controllers have been specifically developed to address issues relating to sub-50 nm flash endurance and reliability."

During the third quarter of 2008, Silicon Motion spent US$24.5 million to repurchase ADSs, made payment on the remaining US$2.0 million for our US$4.0 million Shanghai office space that was announced in the second quarter of 2008, and US$4.4 million for SAP software, IP licensing, design tools, and other assets.

Share Repurchase Program:

On August 15, 2008, the Company announced the completion of a US$40 million share repurchase program that was initiated on March 12, 2008 and announced a second US$40 million share repurchase program. In the third quarter of 2008, the Company repurchased 3.5 million ADSs for a total cost of US$24.7 million. The weighted average price per ADS repurchased was US$7.06.

Management Change:

As part of a Company restructuring, Johnson Yan, Vice President of Product Marketing, departed in the third quarter of 2008 to pursue other interests.

Business Outlook:

Silicon Motion's President and CEO, Wallace Kou, added:

"Looking forward, although we believe we are well positioned, we continue to see a difficult environment over the next few quarters for companies involved in the NAND flash and mobile communications food chain. Our strategy of focusing on long-term OEM customers and on protecting our margins remains unchanged. Additionally, while we continue to prudently invest in projects for next generation solutions, cost containment and cost reduction will remain a top priority for our management team until market conditions recover."

For the fourth quarter of 2008, management expects:



     * Revenue to be flat to down 10% sequentially
     * Non-GAAP and GAAP gross margin to be in the 48- 50% range
     * Operating expense excluding stock-based compensation,
       acquisition-related charges, and one-time items of
       approximately US$15 to 16 million

Discussion of Non-GAAP Financial Measures

To supplement the Company's unaudited selected financial results calculated in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"), the Company discloses certain non-GAAP financial measures that exclude stock-based compensation, acquisition-related charges and one-time items, including, non-GAAP cost of sales, non-GAAP gross profit, non-GAAP selling, general, and administrative expenses, non-GAAP operating income, non-GAAP net income, and non-GAAP earnings per diluted ADS. These non-GAAP measures are not in accordance with or an alternative for GAAP, and may be different from non-GAAP measures used by other companies. We believe that these non-GAAP measures have limitations in that they do not reflect all the amounts associated with the Company's results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate the Company's results of operations in conjunction with the corresponding GAAP measures. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the most directly comparable GAAP measure. We compensate for the limitations of our non-GAAP financial measures by relying upon GAAP results to gain a complete picture of our performance.

Our non-GAAP financial measures are provided to enhance the user's overall understanding of our current financial performance and our prospects for the future. Specifically, we believe the non-GAAP results provide useful information to both management and investors as these non-GAAP results exclude certain expenses, gains and losses that we believe are not indicative of our core operating results and because it is consistent with the financial models and estimates published by many analysts who follow the company. We use non-GAAP measures to evaluate the operating performance of our business, for comparison with our forecasts, and for benchmarking our performance externally against our competitors. Also, when evaluating potential acquisitions, we exclude the items described below from our consideration of the target's performance and valuation. Since we find these measures to be useful, we believe that our investors benefit from seeing the results from management's perspective in addition to seeing our GAAP results. We believe that these non-GAAP measures, when read in conjunction with the Company's GAAP financials, provide useful information to investors by offering:



      -- the ability to make more meaningful period-to-period
         comparisons of the Company's on-going operating results;
      -- the ability to better identify trends in the Company's
         underlying business and perform related trend analysis;
      -- a better understanding of how management plans and measures
         the Company's underlying business; and
      -- an easier way to compare the Company's operating results
         against analyst financial models and operating results of our
         competitors that supplement their GAAP results with non-GAAP
         financial measures.

The following are explanations of each of the adjustments that we incorporate into our non-GAAP measures, as well as the reasons for excluding each or these individual items in our reconciliation of these non-GAAP financial measures:

Stock-based compensation expense consists of non-cash charges incurred as a result of the Company's adoption of SFAS 123R relating to the fair value of stock options and restricted stock units awarded to employees. The Company believes that the exclusion of these non-cash charges provides for more accurate comparisons of our operating results to our peer companies due to the varying available valuation methodologies, subjective assumptions and the variety of award types. In addition, the Company believes it is useful to investors to understand the specific impact the application of SFAS 123R has on its operating results.

Intangible amortization consists of non-cash charges that can be impacted by the timing and magnitude of our acquisitions. The Company considers its operating results without these charges when evaluating its ongoing performance and forecasting its earnings trends, and therefore excludes such charges when presenting non-GAAP financial measures. The Company believes that the assessment of its operations excluding these costs is relevant to its assessment of internal operations and comparisons to the performance of its competitors.

In-process research and development consists of one-time charges incurred in connection with the acquisition of FCI in the second quarter of 2007 and the acquisition of Centronix in the fourth quarter of 2007 that otherwise would not have been incurred and therefore we have excluded the effects of these charges from our non-GAAP operating income and non-GAAP net income. In-process research and development consists of technology projects which, as of acquisition date, had not yet reached technological feasibility and there are no future alternative uses that exist. We believe it is useful for investors to understand the effect of this expense on our statement of operations. This non-GAAP adjustment is intended to reflect acquisition-related expense incurred that is not directly associated with our continuing operations.

Litigation expenses consist of the legal expenses relating to complaints SanDisk filed in the US International Trade Commission and the US District Court for the Western District of Wisconsin.

Foreign exchange gains and losses consists of translation gains and/or losses of non-NT$ denominated current assets and current liabilities, as well as certain other balance sheet items which result from the appreciation or depreciation of non-NT$ currencies against the NT$.

FIN48 tax charge relates to uncertainties about income tax liabilities that had resulted from an arbitrary change in interpretation of tax codes by the Taiwan tax authorities following a routine review of our tax filings.
