Fourth Quarter of 2025 Review

“Our fourth quarter of 2025 outperformance was driven by strength across all our business lines as new products continued to ramp, and we further extended our market share gains in eMMC/UFS and client SSDs,” stated Wallace Kou, President and CEO of Silicon Motion. “Our client SSD controller sales grew over 25% quarter-over-quarter in the fourth quarter of 2025, primarily driven by our industry-leading leading 8-channel and our newly introduced 4-channel PCIe5 controllers. Our eMMC and UFS products increased again sequentially during the fourth quarter of 2025, primarily driven by market share gains. We also experienced strong growth in our automotive segment primarily driven by increased product diversification and new customer ramps. The fourth quarter of 2025 also marked the initial sales of our new boot drive storage products to a leading GPU maker, one of our new growth areas in our rapidly evolving enterprise business. We are pleased by the early progress we are seeing with our new products and the diversification strategy we have set in motion over the past couple of years. Our momentum in our core eMMC/UFS and client SSD controllers continues to be strong as we secure new wins that further our market share gains and our new initiatives in enterprise and automotive are beginning to take hold and will represent significant growth drivers long-term for the Company.”

Discussion of Non-GAAP Financial Measures

To supplement the Company’s unaudited consolidated financial results calculated in accordance with GAAP, the Company discloses certain non-GAAP financial measures that exclude stock-based compensation and other items, including gross profit (non-GAAP), gross margin (non-GAAP), operating expenses (non-GAAP), operating profit (non-GAAP), operating margin (non-GAAP), non-operating income (expense) (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 similarly-titled 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.

5

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.

Dispute related expenses consist of legal, consultant, other fees and resolution related to the dispute.

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.

Realized/Unrealized loss (gain) on investments relates to the disposal and net change in fair value of long-term investments.
