TAIPEI, Taiwan, Feb. 1, 2011 (GLOBE NEWSWIRE) -- Silicon Motion Technology Corporation (Nasdaq:SIMO) (the "Company") today announced its fourth quarter of 2010 financial results. For the fourth quarter of 2010, net sales increased 17% quarter-over-quarter to US$40.0 million from US$34.2 million in the third quarter of 2010. Net income (GAAP) was a loss of US$5.5 million or US$0.19 per diluted ADS, compared to earning US$0.3 million or US$0.01 per diluted ADS in the third quarter of 2010.

Net income excluding stock-based compensation, acquisition-related charges, foreign exchange gain (loss), and other items increased in the fourth quarter to US$5.8 million or US$0.18 per diluted ADS compared with a net income in the third quarter of US$5.1 million or US$0.16 per diluted ADS.

Fourth Quarter 2010 Financial Review

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

"We are excited to report a much stronger than expected fourth quarter of 2010 with revenue increasing by 17% sequentially and 78% year-over-year. Strong unit and revenue growth in our storage and communications businesses drove the better than expected results. While gross margins decreased sequentially, tight operating expense control and higher revenue resulted in our operating margins increasing by 746 basis points to over 17%.

Our mobile storage business continued to outperform as revenue increased 20% sequentially and doubled compared to fourth quarter 2009. This business grew better than expected because of improved NAND flash supply combined with strong emerging market demand. TLC and MLC flash components were more widely available and a significant portion of the incremental TLC supplied to the market was converted into USB flash drives using our advanced TLC controllers. We believe a big portion of these USB flash drives were sold to South America, India, and other emerging markets. Our card controller business, especially our microSD card controller products, delivered robust results from strong sales in China, as well as several new OEM programs. We believe continuing growth of smartphones is a big driver of our strong card controller sales as our bundled card controller sales continued to exceed half of all our SD card sales. We also benefited this quarter from a modest 1% decline in blended controller ASP as our higher value-added products ramped further. Our TLC controller sales increased over 30% sequentially and continued to account for roughly 25% of all our total controller sales. For full year 2010, our controller ASP increased 11% compared to 2009 as we doubled our sales of SSD and embedded flash controllers, led and continued to lead in the introduction of next generation TLC and MLC controllers, and produced unmatched valued-added solutions that provide our customers with competitive performance differentiation and cost advantages.

Our mobile communications business rebounded further as our transceiver sales grew more than 60% sequentially. Mobile TV IC sales were down sequentially due to uneven order patterns with strength in our Korea T-DMB and China CMMB solutions offset by weakness in our Japan and South America I-SDBT solutions."

Sales

Net sales in the fourth quarter were US$40.0 million, an increase of 17% compared with the previous quarter. For the quarter, mobile storage products accounted for 73% of net sales, mobile communications 17% of net sales, multimedia SoCs 8% of net sales, and others 2% of net sales.

Net sales of mobile storage products, which primarily include flash memory card, USB flash drive, SSD and embedded flash controllers, increased 20% from the third quarter of 2010 to US$29.2 million in the fourth quarter.

Net sales of mobile communications products, which primarily include mobile TV IC solutions and handset transceivers, increased 17% from the third quarter of 2010 to US$6.9 million in the fourth quarter.

Net sales of multimedia SoC products, which are primarily embedded graphics processors, decreased 10% from the third quarter of 2010 to US$3.3 million in the fourth quarter.

Gross and Operating Margins

Gross margin excluding stock-based compensation decreased to 45.1% in the fourth quarter from 48.4% in the third quarter primarily because of product mix and NT Dollar appreciation. GAAP gross margin decreased to 45.0% in the fourth quarter from 48.3% in the third quarter.

Operating expenses excluding stock-based compensation, acquisition-related charges, and other items were US$11.2 million, which was lower than the US$13.2 million expended in the third quarter. Research and development expenditures, excluding stock-based compensation, were US$7.2 million, which was lower than the US$7.9 million in the previous quarter. Selling and marketing expenses excluding stock-based compensation were US$2.3 million, which was lower compared to the US$2.9 million reported in the previous quarter. General and administrative expenses excluding stock-based compensation and litigation expenses were US$1.7 million, which was lower compared to the US$2.3 million reported in the previous quarter. Stock-based compensation was US$1.7 million in the fourth quarter, which was lower than the US$1.8 million in the third quarter. Acquisition-related charges were US$0.6 million, a slight increase from US$0.5 million in the previous quarter.

Operating margin excluding stock-based compensation, acquisition-related charges, and other items was 17.3%, an increase from 9.8% in the previous quarter. GAAP operating margin was 12.2%, an increase from the 2.9% in the third quarter.

Other Income and Expenses

Net total other income excluding net foreign exchange gain or loss, and other items was US$0.1 million, similar to the third quarter. GAAP net total other income was a loss of US$9.2 million which was greater than the loss of US$2.4 million in the third quarter due primarily to a foreign exchange loss of US$9.2 million in the fourth quarter. Foreign exchange loss increased in the fourth quarter to US$9.2 million from US$2.4 million in the third quarter as NT Dollar appreciation affected the translational value of US Dollar intercompany financing, cash balance, and other balance sheet items.

Earnings

Net income excluding stock-based compensation, acquisition-related charges, net foreign exchange gain or loss, and other items was US$5.8 million this quarter, an increase from US$5.1 million in the third quarter. Diluted earnings per ADS excluding stock-based compensation, acquisition-related charges, net foreign exchange gain or loss, and other items was US$0.18, an increase from US$0.16 in the previous quarter.

Net income (GAAP) was a loss of US$5.5 million or US$0.19 per diluted ADS, compare to earning of US$0.3 million or US$0.01 per diluted ADS in the third quarter of 2010.

Balance Sheet

Cash, cash equivalents, and short-term investments decreased to US$54.8 million from US$58.4 million at the end of the third quarter of 2010 due primarily to a decrease in accounts payable and an increase in accounts receivable.

Cash Flow

Our cash flows were as follows:

During the fourth quarter of 2010, we spent US$1.1 million in capital expenditures primarily relating to the purchase of software and design tools.

Business Outlook:

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

"We are proud of the growth we generated in 2010 but we believe that the opportunities ahead for 2011 are even more exciting. Flash supply is expected to increase further in 2011 as the major flash vendors ramp up new manufacturing facilities while demand is expanding beyond the traditional card and USB flash drive markets into exciting new embedded opportunities in smartphones, tablets and other devices. Additionally, we are leveraging our controller technology leadership to enter new OEMs programs involving major flash vendors. As the year progresses, I intend to discuss more about our design wins involving our embedded solutions as well as our OEM programs."

For the first quarter of 2011, management expects:

  --  Revenue to be flat to down 10% sequentially
  --  Gross margin excluding stock-based compensation to be in the 46% to 48%
      range
  --  Operating expenses excluding stock-based compensation,
      acquisition-related charges, and other items of approximately US$12 to
      US$14 million


For the full year 2011, management expects:

  --  Revenue to be up 20% to 30% compared with full year 2010
  --  Gross margin excluding stock-based compensation to be in the 46% to 48%
      range
  --  Operating expenses excluding stock-based compensation,
      acquisition-related charges, and other items of approximately US$53 to
      US$56 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 other 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 of these individual items in our reconciliation of these non-GAAP financial measures:

Stock-based compensation expense consists of non-cash charges related 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 of share-based compensation on its operating results.

Acquisition-related charges consist of non-cash charges that can be impacted by the timing and magnitude of our acquisitions. We consider our operating results without these charges when evaluating our ongoing performance and forecasting our earnings trends, and therefore excludes such charges when presenting non-GAAP financial measures. We believe that the assessment of our operations excluding these costs is relevant to our assessment of internal operations and comparisons to the performance of our competitors. Acquisition-related charges include the following:

  --  Amortization of intangible assets relates to the amortization of core
      technology, customer relationship, and other intangibles acquired as
      part of an acquisition.


Litigation expenses consist of legal expenses relating to intellectual property disputes, commercial claims and other types of litigation. We consider litigation to be an unusual, non-recurring activity that does not occur regularly in the normal course of our business and therefore exclude these types of charges when presenting non-GAAP financial measures.

Gain from settlement of litigation relates to one-time payments in connection with favorable settlements of certain litigations with ASE and ANP.

Impairment of goodwill and long-lived assets evaluates the recoverability of goodwill and long-lived assets annually, or sooner if events or changes in circumstances indicate that the carrying amount may not be recoverable.

Impairment of long-term investments relates to the other-than-temporary, non-operating write down of the Company's minority stake investments. We do not consider these investments which were made before 2007 to be strategic and exclude the performance of these investments when evaluating our ongoing performance and forecasting our earnings trends, and therefore excludes losses (and gains) from the investments when presenting non-GAAP financial measures.

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$. We do not use financial instruments to manage the impact on our operations from changes in foreign exchange rates, and because our operations are subject to fluctuations in foreign exchange rates, we therefore exclude foreign exchange gains and losses when presenting non-GAAP financial measures.
