TAIPEI, Taiwan and MILPITAS, Calif., Feb. 04, 2021 (GLOBE NEWSWIRE) -- Silicon Motion Technology Corporation (NasdaqGS: SIMO) (“Silicon Motion” or the “Company”) today announced its financial results for the quarter ended December 31, 2020. For the fourth quarter, net sales (GAAP) increased sequentially to $143.9 million from $126.0 million in third quarter 2020. Net income (GAAP) declined to $1.4 million or $0.04 per diluted ADS (GAAP) from a net income (GAAP) of $24.3 million or $0.70 per diluted ADS (GAAP) in third quarter 2020.

For the fourth quarter, net income (non-GAAP) increased to $29.9 million or $0.86 per diluted ADS (non-GAAP) from a net income (non-GAAP) of $26.7 million or $0.76 per diluted ADS (non-GAAP) in third quarter 2020.

Fourth Quarter 2020 Review
“Fourth quarter results were stronger than expected as customer procurement continues to be robust,” said Wallace Kou, President and CEO of Silicon Motion. “Sales of our eMMC+UFS controllers for smartphones and IOT devices were especially strong and our SSD controllers continued to benefit from strong PC demand. Sales of our SSD solutions were however seasonally soft.”

During the fourth quarter, we had $5.6 million of capital expenditures for the routine purchase of testing equipment, software, design tools and other items.

Returning Value to Shareholders
On October 26, 2020, our Board of Directors declared a $1.40 per ADS annual dividend to be paid in quarterly installments of $0.35 per ADS. On November 25, 2020, we paid $12.1 million to shareholders as the first installment of our annual dividend.

On November 21, 2018, we announced that our Board of Directors had authorized a new program for the Company to repurchase up to $200 million of our ADS over a 24-month period. On October 26, 2020, the Board of Directors of the Company authorized the extension of the expiration of this program to November 21, 2021. Since the start of this program, we have repurchased $84.8 million of our ADSs and $115.2 million remains available for repurchase under the program. There were no share repurchases in the fourth quarter.

Business Outlook
“We are kicking-off 2021 with what we believe will be an unseasonally strong first quarter and an extremely strong order book for the year, with sales growth currently capped by foundry supply availability,” said Wallace Kou, President and CEO of Silicon Motion. “We are seeing strong, broad-based OEM demand and design activities for our SSD and eMMC+UFS controllers and expect this momentum to carry over to 2022. PC OEMs are driving strong demand for PCIe NVMe SSD controllers and smartphone and IOT OEMs for UFS and eMMC mobile embedded storage controllers.”

For the first quarter of 2021, management expects:

	GAAP	Non-GAAP Adjustment	Non-GAAP
Revenue	$154m to $161m 7% to 12% Q/Q	--	$154m to $161m 7% to 12% Q/Q

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 and other items, including gross profit (non-GAAP), operating expenses (non-GAAP), operating profit (non-GAAP), net income (non-GAAP), and earnings per diluted ADS (non-GAAP). These non-GAAP measures are not in accordance with or an alternative to 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 they are 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 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.

SSD solutions restructuring are charges related to the restructuring of our underperforming Shannon and Bigtera product lines and include goodwill and intangible assets impairment expenses, the write-down of NAND flash and SSD inventory valuation and customer sales returns and accounts receivable attributable to these product lines.

Amortization of intangibles assets 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.

Litigation expenses consist of legal expenses relating to intellectual property disputes, commercial claims and other types of litigation. While litigation may arise in the ordinary course of our business, we nevertheless consider litigation to be an unusual and unplanned activity and therefore exclude this charge when presenting non-GAAP financial measures.

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

Gain on disposal of long-term investments relate to gains from our sale of FCI, our specialty RF IC product line, and the sale of our investment in ProGrade, a professional-grade memory card manufacturer.
