For the first quarter of 2023, net sales (GAAP) decreased sequentially to $124.1 million from $200.8 million in the fourth quarter of 2022.

Business Review

Wallace Kou, President & CEO of Silicon Motion commented:

“Market conditions are currently extremely challenging, a view shared by all our NAND flash maker and other key customers. End-markets for PCs and smartphones remain soft and many suppliers into these products have focused on working down inventory, including client SSD and eMMC/UFS embedded storage devices, which has had a negative effect on our sales. Despite this, we are encouraged to see some of our customers’ order patterns improving in the second quarter, and combined with our strong design win momentum, we are optimistic that this could lead to a stronger market rebound towards the end of 2023.”

“We are actively taking steps to right size our business and protect our profitability. We are also working on reducing our manufacturing costs to improve gross margins in the near-term. Regarding operating expenses, we have been taking steps to reduce our compensation-related costs, the largest item in our operating expense, as well as retiring certain unprofitable, non-core product lines and pushing out certain R&D project tape-outs and related expenses. Overall, we believe we are putting the right actions in place to improve our overall profitability throughout 2023.”

“Despite today’s difficult operating environment, we are working hard with our customers and our manufacturing partners to continue delivering cost effective, high-performance, differentiated solutions that will enable us to maintain our leadership in the storage controller market. We are confident that we have the right customers, strong design win momentum and are taking necessary steps to ensure the long-term growth of our revenue and profitability.”

Acquisition Update

On May 5, 2022, Silicon Motion agreed to be acquired by MaxLinear, Inc. (“MaxLinear”) with (a) holders of Silicon Motion ordinary shares, par value $0.01 (each, a “Share”), to receive $23.385 in cash and 0.097 shares of common stock, par value $0.0001, of MaxLinear (“MaxLinear Common Stock”) for each Share that they hold (other than certain customary excluded Shares), and (b) ADS holders to receive $93.54 in cash and 0.388 shares of MaxLinear Common Stock for each ADS that they hold (other than ADSs representing certain customary excluded Shares), in each case, with cash in lieu of any fractional shares of MaxLinear Common Stock as set forth in the merger agreement (collectively, the “Transaction”). On August 31, 2022, shareholders at Silicon Motion’s Extraordinary General Meeting of shareholders approved the Transaction.

The Transaction is not subject to any financing condition but is pending satisfaction of customary closing conditions, including antitrust approval from China’s State Administration for Market Regulation (“SAMR”). MaxLinear and Silicon Motion cannot predict with certainty the length of SAMR’s review but expect a final determination by SAMR in the second or third quarter of 2023, or even later. On June 27, 2022, the waiting period under the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), expired with respect to the Transaction. If the Transaction has not closed by June 27, 2023, the parties will need to re-file under the HSR Act.

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 income (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 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.

Restructuring charges relate to the restructuring of our underperforming product lines, principally the write-down of NAND flash, embedded DRAM and SSD inventory valuation and severance payments.

M&A transaction expenses consist of legal, financial advisory and other fees related to the Transaction.

Loss from settlement of litigation relates to an expense accrued in connection with a settlement of a lawsuit.

Foreign exchange loss (gain) consists 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.

Unrealized holding loss (gain) on investments relates to the difference between market value and cost of long-term investments.
