Fourth Quarter 2014 Financial Review

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

“As expected, our fourth quarter revenue was seasonally soft, largely due to the seasonality of eMMC sales. Our fourth quarter revenue increased 53% as compared to the fourth quarter of 2013, led by a strong 70% year-over-year increase of our embedded storage sales, with strong growth by our eMMC and client SSD controllers.

For full-year 2014, we achieved the highest level of revenue in our corporate history. We are extremely pleased with the stellar growth of our eMMC sales, which are now about 40% of total corporate sales, and with the solid position that our client SSD controllers have established with our NAND flash, storage OEM and module maker partners. Our overall embedded storage product sales, consisting primarily of our eMMC, client SSD and industrial SSD controllers have grown to account for over half of our total corporate sales.

In the first quarter-to-date, our client SSD controllers have already achieved a number of important milestones. Micron and another NAND flash vendor announced that they will start shipping SSDs with our controllers. Our storage OEM partner has already started shipping SSDs with our controllers to three global tier-1 PC OEMs. Our turnkey TLC SATA 3 client SSD controller, the world’s first merchant solution, which began commercial sampling in August last year, began initial commercial sales to a module maker customer. Additionally, we secured an SSD platform win at another NAND flash OEM, which brings the total number of NAND flash partners that will enter production in 2015 with our client SSD controllers to four.”

Sales

Net sales in the fourth quarter were US$80.5 million, a decrease of 7% compared with the third quarter. For the quarter, mobile storage products accounted for 81% of net sales and mobile communications 16% of net sales.

Net sales of our mobile storage products, which primarily include eMMC, SSD, memory card and USB flash drive controllers, decreased 9% sequentially in the fourth quarter to US$65.5 million.

Net sales of mobile communications products, which primarily include LTE transceivers and mobile TV IC solutions, increased 5% sequentially to US$13.3 million in the fourth quarter.

Gross and Operating Margins

Gross margin (non-GAAP) decreased to 52.5% in the fourth quarter as compared to 52.9% in the third quarter. GAAP gross margin decreased in the fourth quarter to 52.4% as compared to 52.8% in the third quarter.

Operating expenses (non-GAAP) in the fourth quarter were US$21.4 million, a decrease from US$22.1 million in the third quarter. Operating margin (non-GAAP) was 25.9%, a decrease from 27.3% in the previous quarter. GAAP operating margin was 20.7% for the fourth quarter, a decrease from 21.9% in the third quarter.

Other Income and Expenses

Net total other income (non-GAAP) was US$0.6 million, a slight increase from the third quarter. GAAP net total other income was US$0.2 million, a slight increase from the third quarter.

Earnings

Net income (non-GAAP) was US$16.6 million for the fourth quarter, a decrease from US$19.7 million in the third quarter. Diluted earnings per ADS (non-GAAP) were US$0.48 in the fourth quarter, a decrease from US$0.57 per ADS in the third quarter.

GAAP net income was US$11.9 million for the fourth quarter, a decrease from US$14.6 million in the third quarter. Diluted GAAP earnings per ADS in the fourth quarter were US$0.35, a decrease from US$0.43 per ADS in the third quarter.

Balance Sheet

Cash and cash equivalents, and short-term investments increased at the end of the fourth quarter to US$194.9 million from US$165.2 million at the end of the third quarter.

Cash Flow

Our cash flows were as follows:


3 months ended December 31, 2014


	(In US$ millions)
Net income		11.9
Depreciation & amortization		1.9
Changes in operating assets and liabilities		18.1
Others		5.1

Net cash provided by (used in) operating activities		37.0

Acquisition of property and equipment		(1.9	)

Returning Value to Shareholders

On October 15, 2014 the Board of Directors of the Company declared a US$0.15 per ADS quarterly dividend. On November 19, we paid $5.1 million as dividend payments to our shareholders.

Business Outlook:

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

“2014 was an outstanding year for Silicon Motion. We believe our strong 2014 sets the stage for continuing growth in 2015. We are confident that our SK Hynix eMMC business will continue to grow and our client SSD controller sales will scale as our OEM projects enter production. We expect our first quarter to be seasonally soft due to removable storage seasonality which should offset the initial ramp of our OEM client SSD sales. We expect our eMMC sales to be relatively flat sequentially, but represent an increase of over 50% as compared to the first quarter of 2014.”

For the first quarter of 2015, management expects:

•

Revenue to decrease 5% to 0% sequentially

•

Gross margin (non-GAAP) to be in the 50% to 52% range

•

Operating expenses (non-GAAP) of approximately US$22 to $23 million

For full-year 2015, management expects:

•

Revenue to increase 15 % to 25 % as compared to full-year 2014

•

Gross margin (non-GAAP) to be in the 49.5% to 51.5% range

•

Operating expenses (non-GAAP) of approximately US$91 to $97 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 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 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 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.

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.

Other non-recurring items:

•

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, non-recurring and unplanned activity and therefore exclude this charge when presenting non-GAAP financial measures.

•

Vendor dispute charges relate to the write down of certain unsalable inventory due to defects in the components provided by our vendor. These parts were supplied to us at a quality below levels previously specified and agreed. All parts known to be defective have been identified and are within our control. We have resolved this matter with our vendor and recovered in 1Q 2013 the full value of the inventory being written off. This charge (as well as the amount recovered) has been excluded from our non-GAAP results as we believe this is an unusual, non-recurring and unplanned activity.
