Letter to Shareholders

Dear Shareholders,

2022 was another record year for Silicon Motion. Following a record year in 2021, sales increased to 

$946 million and earnings per ADS* increased to $6.36,despite macroeconomic challenges that affected 

global demand for smartphones and PCs in the second half of 2022. Silicon Motion continues to set the 

industry standard for product excellence, innovation, and customer service. Our strong performance 

is driven by our diversified, long-standing customer relationships and high-quality product solutions 

for SSD controllers and embedded eMMC+UFS controllers. 

Key 2022 business milestones include:

• Full-year revenue and earnings per ADS* both achieved a second consecutive year of corporate record 

highs

• eMMC+UFS controller sales increased by 15-20% year-over-year and achieved another record high

• SSD controller sales decreased 5-10% year-over-year

• SSD Solutions sales increased 30-35% year-over-year

• On May 5, 2022, we announced the agreement to be acquired by MaxLinear 

As we began 2022, demand industrywide remained strong as consumers continued to purchase new PCs 

and handsets, though this elevated demand continued to strain the global supply chain. For the first half of 

2022, our revenue increased 23% compared to the first half of 2021. As the global economy weakened in 

the second half of the year, alongside persistently high inflation worldwide, consumer demand slowed 

significantly across our industry. While our teams did an admirable job navigating through global headwinds, 

these challenges resulted in year-on-year declines in our revenue in the second half of 2022. Iʼm very proud 

of the determination and resilience our team showed during this period, as we focused on operating with 

discipline, executing our strategy and serving our customers with the remarkable service for which Silicon 

Motion is known globally. Despite these challenges, we finished the year with record revenue and earnings 

per ADS*.

Our SSD controller sales declined 5-10% in 2022 as compared to 2021 and accounted for 45-50% of our total 

sales. The Covid-19 driven strength in the PC market continued into 2022, but by the second half of the year, this 

demand tapered off. Our team continued to deliver exciting momentum and successes during the year. We 

secured additional design wins with our NAND flash maker customers and significantly expanded our end-market 

opportunities. We continued to invest in next-generation controller solutions, bringing to market innovative 

solutions targeting high performance, as well as cost-effective solutions that target mainstream and entry-level 

products. We are expanding our SSD footprint beyond the traditional PC market and seeing strong traction in 

portable SSDs as well as SSDs for emerging markets like automotive, industrial, networking equipment and IoT 

products. Our focus will be to continue to deliver a broad range of solutions for our expanding customer base and 

become more resilient to deliver consistent growth and profitability long-term.

04

For our eMMC+UFS business, sales increased 15-20% in 2022 year-over-year and accounted for 

35-40% of our total sales. Despite an industry-wide slowdown of smartphone shipments in the 

second half of 2022, our revenue growth outpaced the industry as our efforts to diversify our 

customer base accelerated, especially with our customers targeting top smartphone OEMs. Overall, our 

broad customer base of both flash makers and module makers has positioned us well to take 

advantage of the strong smartphone sales globally in 2022 as well as expand and scale into additional 

end-markets like IoT/AI devices, industrial, commercial, and automotive applications. 

Sales of our SSD Solutions remained at 5-10% of our total sales in 2022 and increased 30-35% 

year-on-year as demand for our Ferri storage solutions scaled quickly in industrial, enterprise 

and automotive markets. Our broad-based customer and end-market base provided strong demand 

for these products.

We are proud of our accomplishments in 2022, and we remained focused on developing high performance, 

high value controller solutions for our NAND flash maker customers as well as our module maker customers 

that together, enable us to serve an increasingly broad range of end-markets. 

As we have disclosed, on August 16, 2023, we terminated the Merger Agreement with MaxLinear.  

MaxLinear had previously purported to terminate the Merger Agreement on July 26, 2023.  MaxLinear 

did not provide any factual basis for its purported termination, and we believe its actions constituted 

a willful and material breach of the Merger Agreement. We are seeking payment of the $160 million 

termination fee, further substantial damages, interest, and costs from MaxLinear, in the Singapore 

International Arbitration Centre, which is the venue for dispute resolution under the Merger Agreement. 

Our financial performance and operational strength underscore Silicon Motionʼs strength as a standalone 

business, and we have significant opportunities for long-term growth and value creation. Our unwavering 

focus on serving our customers positions us well for the market rebound in late 2023 and beyond.

And lastly, especially in light of the global economic uncertainties and the challenges that we, and many 

in our industry, are facing from weaker end-market demand, I remain grateful to our tireless employees 

for their dedication and commitment to serving our customers as well as the ongoing support of our 

shareholders.

Sincerely,

Wallace Kou

President and Chief Executive Officer

Unless otherwise indicated, our financial information presented in this annual report has been prepared in accordance with U.S. GAAP.

On May 5, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with MaxLinear, Inc., a Delaware
Corporation (“MaxLinear”), and Shark Merger Sub, an exempted company with limited liability incorporated under the law of the Cayman Islands and a
wholly owned subsidiary of MaxLinear (“Merger Sub”). The Merger Agreement and the Merger (as defined below) have been unanimously approved by
the boards of directors of the Company, MaxLinear and Merger Sub. The Merger Agreement provides that, upon the terms and subject to the satisfaction
or waiver of the conditions set forth therein, Merger Sub will be merged with and into the Company (the “Merger”) in accordance with Part XVI of the
Companies Act (2022 Revision) of the Cayman Islands, with the Company continuing as the surviving company and a wholly owned subsidiary of
MaxLinear.

Under the terms of the Merger Agreement, the transaction consideration will consist of US$93.54 in cash and 0.388 shares of MaxLinear common

stock for each ADS of the Company (other than ADSs representing certain customary excluded shares) and US$23.385 in cash and 0.097 shares of
MaxLinear common stock for each ordinary share of the Company not represented by ADSs (other than 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. Upon the closing of the Merger, the
current MaxLinear stockholders are expected to own approximately 86% of the combined company and former security holders of the Company are
expected to own approximately 14% of the combined company. Based on the closing price of MaxLinear shares on May 4, 2022,

1

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
the implied value of the total transaction consideration for the Company is approximately $4.3 billion. Pursuant to the Merger Agreement, MaxLinear
will assume the Company’s vested and unvested employee stock-based compensation awards.

On July 13, 2022, MaxLinear’s registration statement on Form S-4, which registered shares of MaxLinear common stock to be issued in the
Merger, was declared effective by the SEC. On July 13, 2022, we called for an extraordinary general meeting of shareholders (the “EGM”) to approve
the Merger Agreement, the Merger and all other transactions and arrangements contemplated by the Merger Agreement. On August 31, 2022, we held
the EGM at which our shareholders approved (a) the Merger Agreement; (b) the plan of merger required to be filed with the Registrar of Companies in
the Cayman Islands; (c) the Merger itself, on the terms and subject to the conditions set forth in the Merger Agreement; and (d) all other transactions and
arrangements contemplated by the Merger Agreement.

The Merger is subject to customary closing conditions, including antitrust approval by the State Administration for Market Regulation (“SAMR”)

in China. MaxLinear and the Company 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 (the “HSR Act”) expired with respect to the Merger. If the parties have not closed the Merger by June 27, 2023, they will need to re-file
under the HSR Act.

Unless indicated otherwise by the context, the discussion in this annual report regarding our future business plans and activities does not take into
account the effect of the consummation of the Merger, which is currently anticipated to be in either the second or third quarter of calendar year 2023, or
even later. However, the exact timing of completion of the Merger cannot be predicted because the Merger continues to be subject to the closing
conditions specified in the Merger Agreement which have not been satisfied, many of which are outside of our control.

For further information on the Merger Agreement and its conditions, as well as on the EGM, see our reports on Form 6-Ks, including our Proxy
Statement on Form 6-K (the “Merger Proxy Statement,” and together, the “Merger-Related Materials”), filed with or furnished to the SEC on May 6,
2022, June 28, 2022, July 13, 2022, July 19, 2022, August 31, 2022 and September 1, 2022, respectively.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This annual report on Form 20-F contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as
amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are subject to the
“safe harbor” created by those sections. These forward-looking statements include statements regarding our financial position; our expectations
concerning future operations, margins, profitability, liquidity and capital resources; our business strategy and other plans and objectives for future
operations; the expected timing of the closing of the Merger; the satisfaction or waiver of any conditions to the Merger; anticipated benefits, growth
opportunities and other events relating to the Merger; and all other statements that are not historical facts. In some cases, you can identify forward-
looking statements by terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “thinks,” “estimates,”
“seeks,” “predicts,” “potential,” and similar expressions. Although we believe that these statements are based on reasonable assumptions, they are
subject to numerous factors, risks and uncertainties, including, but are not limited to, those identified under “Risk Factors” and elsewhere in this annual
report on Form 20-F and the Merger Proxy Statement that could cause actual results and performance to be materially different from those projected.
Given these factors, risks and uncertainties, you should not place undue reliance on these forward-looking statements. Also, these forward-looking
statements represent our estimates and assumptions only as of the date of this filing. Except as required by law, we assume no obligation to update these
forward-looking statements, even if new information becomes available in the future.

Risk Factors

Our business, operations and financial results are subject to various risks and uncertainties, including those described below, that could adversely
affect our business, financial condition, results of operations and cash flows and the trading price of our ADSs could decline. These risk factors do not
identify all risks that we face; our operations could also be affected by factors that are not presently known to us or that we currently consider to be
immaterial to our operations. Due to risks and uncertainties, known and unknown, our past financial results may not be a reliable indicator of future
performance and historical trends should not be used to anticipate results or trends in future periods. The following factors, among others, could cause
our actual results to differ materially from those expressed in forward-looking statements made by us in filings with the SEC, press releases,
communications with investors and oral statements. You should also refer to the other information set forth in this Form 20-F, including in the Financial
Statements.

Below is a summary of the principal risks we face, followed by a more detailed description of the risk factors being set forth in summary fashion.

Risks Related to the Merger

•

•

•

•

  The Merger may not be completed, due to the failure of the parties to achieve the closing conditions or otherwise; such a failure could

negatively impact the price of our ADSs, our business, financial condition, and results of operations.

  The fact that there is a Merger pending could materially impact our business and results of operations.

  Some of our directors and officers may have interests that may be different from, or in addition to, the interests of our shareholders.

  The restrictions on our ability to solicit or engage in negotiations with respect to other potential acquisition proposals may discourage other

potential transactions that may be favorable to our shareholders.

•

•

  If the Merger is not consummated by the outside date set forth in the Merger Agreement (as it may be extended in accordance with the
Merger Agreement (the “Outside Date”)), either we or MaxLinear may, under certain circumstances that may be beyond our control,
choose not to proceed with the Merger.

  Our shareholders could file claims challenging the Merger, which may delay or prevent the closing of the Merger and may cause us to

incur substantial defense or settlement costs, or otherwise adversely affect us.

Risks Related to our Business

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

  Our results of operations are subject to substantial quarterly and annual fluctuations due to a number of factors that could adversely affect

our business and the price of our ADSs.

  We are subject to the cyclical nature of the semiconductor industry, which has been subject to significant fluctuations.

  Inflation and inflationary pressures could have an adverse effect on our business, financial condition, results of operations and cash flows.

  We are subject to order and shipment uncertainties and our results of operations could be materially adversely affected if we are unable to

accurately forecast customer demand.

  The demand for our products depends in part on the market conditions in the industries into which they are sold. Fluctuations in demand

for our products or a market decline in any of these industries could have a material adverse effect on our results of operations.

  The COVID-19 pandemic continues to impact our business and could materially adversely affect our financial condition and results of

operations.

  We may pursue acquisitions, investments and dispositions, which could adversely affect our results of operations.

  We depend on a few large customers for a significant portion of our revenues and a loss of some of these customers would result in the loss

of a significant portion of our revenues.

  NAND industry cyclicality could adversely affect our growth and profitability.

  If we fail to accurately anticipate and respond to market trends or fail to develop and introduce new or enhanced products to address these

trends on a timely basis, our ability to attract and retain customers could be impaired and our competitive position could be harmed.

  Our gross margin and results of operations may be adversely affected in the future by a number of factors, including decreases in average

selling prices of products over time, increased raw material costs and shifts in our product mix.

  Our SSD solutions product performance could continue to adversely affect our results of operations.

  The loss of any of our key personnel or the failure to attract or retain specialized technical or management personnel could impair our

ability to grow our business.

  We rely on independent semiconductor foundries and subcontractors for the fabrication, assembly and testing of our integrated circuits, and

any limitation of their available capacity to us or failure to fulfill our orders satisfactorily could damage our relationships with our
customers, decrease our sales or limit our ability to grow our business.

  Failure to protect our intellectual properties or maintain the rights to certain other technologies may negatively impact our ability to

compete.

  Failure to successfully defend against intellectual property lawsuits brought against us may adversely affect our business.

•

•

•

•

  Because the markets in which we compete are highly competitive and many of our competitors have greater resources than we have, we

cannot be certain that our products will compete favorably in the marketplace.

  Our products must meet exacting specifications and undetected defects and failures may occur, which may cause customers to return or

stop buying our products and may expose us to product liability risk and risks of indemnification against defects in our products.

Risks Related to the Merger

The Merger may not be completed, due to the failure of the parties to achieve the closing conditions or otherwise; such a failure could negatively
impact the price of our ADSs, our business, financial condition, and results of operations.

The Merger is subject to the satisfaction or waiver of certain closing conditions described in the Merger Agreement, including, among others:

•

•

•

•

  approval by Nasdaq of the listing of the shares of MaxLinear common stock to be issued in the Merger;

  the absence of certain orders that restrain, enjoin or prohibit the consummation of the Merger;

  the expiration or termination of the applicable HSR Act waiting period and the receipt of clearance from SAMR;

  subject to specified exceptions and qualifications for de minimis inaccuracies, materiality and material adverse effect, the accuracy of the

representations and warranties with respect to the Company,

6

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
MaxLinear and Merger Sub, except to the extent any such inaccuracy would not reasonably be expected to have a material adverse effect
on the Company or MaxLinear;

  compliance in all material respects by the Company, MaxLinear and Merger Sub with their respective covenants and agreements contained

in the Merger Agreement; and

  the absence of a continuing material adverse effect on the Company since the date of the Merger Agreement.

•

•

Although the currently applicable HSR Act waiting period has expired, if the parties have not closed the Merger by June 27, 2023, they will need
to re-file under the HSR Act. In addition, no assurance can be given that each of the other conditions will be satisfied. The Merger Agreement may also
be terminated under the circumstances described in the Merger Proxy Statement. If the conditions are not satisfied or waived in a timely manner and the
merger is delayed, payment of the transaction consideration will also be delayed. See “Explanatory Note”.

If the Merger is not completed (including in the case the Merger Agreement is terminated), our ongoing business may be adversely affected. Under

such a scenario, our directors, senior management and other employees will have expended extensive time and effort and will have experienced
significant distractions from their work, and we will have incurred significant transaction costs, during the pendency of a failed transaction. In addition,
our continuing business relationships with business partners and employees, and the market’s perceptions of our prospects, could be adversely affected,
which could have a material adverse impact on the trading price of our ADSs.

We also could be subject to litigation related to any failure to complete the Merger. If these risks materialize, our financial condition and results of

operations could be materially adversely affected.

The fact that there is a Merger pending could materially impact our business and results of operations.

While the Merger is pending, we are subject to a number of risks that may harm our business and results of operations, including:

•

•

•

•

•

•

  the diversion of management and employee attention from implementing growth strategies in existing markets or in new markets that we

are targeting;

  potential diversion of public attention from the positioning of our independent brand and products in a manner that appeals to customers;

  the fact that we will continue to incur expenses related to the Merger prior to its closing;

  our potential inability to respond effectively to competitive pressures, industry developments and future opportunities, in particular, given
certain restrictions on the conduct of our business during the interim period between signing and closing of the Merger due to pre-closing
covenants in the Merger Agreement;

  being subject to costly litigation associated with the Merger; and

  our current and prospective employees may be uncertain about their future roles and relationships with us following completion of the

Merger, which may adversely affect our ability to attract and retain key personnel.

Some of our directors and officers may have interests that may be different from, or in addition to, the interests of our shareholders.

Certain of the Company’s officers and directors may have interests in the transactions contemplated by the Merger Agreement that may be

different from, or in addition to, those of the Company’s other shareholders,

7

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
which interests are described in the Merger Proxy Statement. These interests include, among other things, the rights to accelerated vesting of equity
awards, the indemnification and insurance and certain payments and benefits provisions contained in or permitted by the Merger Agreement.

The restrictions on our ability to solicit or engage in negotiations with respect to other potential acquisition proposals may discourage other
potential transactions that may be favorable to our shareholders.

Until the Merger is completed or the Merger Agreement is terminated, the Merger Agreement generally prohibits us from soliciting, encouraging

or engaging in negotiations with respect to acquisition proposals or other business combinations.

If the Merger is not consummated by the Outside Date, either we or MaxLinear may, under certain circumstances that may be beyond our
control, choose not to proceed with the Merger.

The Merger is subject to the satisfaction or waiver of certain closing conditions described in the Merger Proxy Statement and set forth in the

Merger Agreement. The fulfillment of certain of these conditions is beyond our control, such as, (1) approval by Nasdaq of the listing of the shares of
MaxLinear common stock to be issued in the Merger, (2) the absence of certain orders that restrain, enjoin or prohibit the consummation of the Merger,
(3) the expiration or termination of the applicable waiting period under the HSR Act and (4) the receipt of clearance SAMR. If the Merger has not been
completed by the Outside Date, either the Company or MaxLinear may generally terminate the Merger Agreement, notwithstanding the prior receipt of
the approval of the Merger by the Company’s shareholders, except that the right to terminate the Merger Agreement would not be available to a party
that is in material breach of the Merger Agreement or whose actions or omissions, which constitute a breach of the Merger Agreement, are a principal
cause of, or primarily result in, the failure of the Merger to be completed on or before that date.

Our shareholders could file claims challenging the Merger, which may delay or prevent the closing of the Merger and may cause us to incur
substantial defense or settlement costs, or otherwise adversely affect us.

Our shareholders may file lawsuits challenging the Merger. The outcome of any claim and / or litigation is uncertain. Such litigation, if not
resolved, could prevent or delay completion of the Merger and result in substantial costs to the Company, including any costs associated with the
indemnification of directors and officers. One of the conditions to the closing of the Merger is the absence of any provision of applicable law or order by
any governmental entity that has the effect of restraining, enjoining or otherwise prohibiting the consummation of the Merger. Therefore, if a plaintiff
were successful in obtaining an injunction prohibiting the consummation of the Merger on the agreed-upon terms, then such injunction may prevent the
Merger from being completed, or from being completed within the expected timeframe. The defense or settlement of any lawsuit or claim that remains
unresolved at the time the Merger is completed may adversely affect the Company’s business, financial conditions, results of operations and cash flows.

Risks Related to our Business

Our results of operations are subject to substantial quarterly and annual fluctuations due to a number of factors that could adversely affect our
business and the price of our ADSs.

Our operating results have fluctuated in the past and are likely to fluctuate in the future. These fluctuations may occur on a quarterly and on an

annual basis and are due to a number of factors, many of which are beyond our control, including, but not limited to:

•

•

  business conditions, including downturns in market segments, such as the computing and mobile markets, in which we operate, or in

global and regional economies;

  the availability and pricing of third-party semiconductor foundry, assembly, packaging and testing services, including their yield, and

related raw materials;

8

 
 
 
 
 
•

•

•

•

•

•

•

•

•

•

•

•

•

•

  significant reduction, changes in timing or cancellation of customer orders;

  regional and global inflationary pressures;

  changes in our customers’ sales outlook, purchasing patterns and inventory adjustments;

  the loss of a design-win or key customer;

  competitive and pricing pressures, including new product introductions and other actions taken by competitors;

  availability and cost of NAND flash used in our and our customer’s products;

  changes in our product mix, especially relating to the sales of our NAND flash controllers and SSD solutions, and their effect on our gross

margin;

  the unpredictable consequences of public health emergencies such as COVID-19, further discussed in the following Risk Factor, and

natural or man-made disasters;

  inventory impairment uncertainties relating to the effects of volatile NAND flash price and excess inventory;

  our ability to develop, market and transition to volume production of new or enhanced products in a cost-effective and timely manner;

  changes in the timing and number of tape-outs and other significant R&D expenses;

  competitive pressure to attract, retain and motivate a highly skilled workforce, including R&D personnel;

  intellectual property disputes; and

  changes in our effective tax rate.

These and other factors make it difficult for us to forecast and could materially adversely affect our quarterly or annual operating results. We could

fail to achieve the operating targets that we have announced, such as revenue growth, gross margin, and operating margin. In addition, our operating
results in the future may be below the expectations of securities analysts or investors, which would likely cause the market price of our ADSs to decline.
Any variations in our period-to-period performance may also cause the market price of our ADSs to decline. Accordingly, you should not rely on the
results of any prior periods as a reliable indicator of our future operating performance.

We are subject to the cyclical nature of the semiconductor industry, which has been subject to significant fluctuations.

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and

price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry has experienced
significant fluctuations, often connected with, or in anticipation of, maturing product cycles and new product introductions of both semiconductor
companies’ and their customers’ products and fluctuations in general economic conditions. Deteriorating general worldwide economic conditions,
including reduced economic activity, concerns about credit and inflation, increased energy costs, decreased consumer confidence, reduced corporate
profits, decreased spending and similar adverse business conditions, would make it very difficult for our customers, our suppliers, and us to accurately
forecast and plan future business activities and could cause U.S. and foreign businesses to slow spending on our products. We cannot predict the timing,
strength, or duration of any economic slowdown or economic recovery. If the economy or markets in which we operate deteriorate, our business,
financial condition, and results of operations would likely be materially and adversely affected.

Downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of

average selling prices. Upturns have been characterized by increased product demand and production capacity constraints created by increased
competition for access to third-party foundry, assembly and test capacity. We are dependent on the availability of such capacity to manufacture,
assemble and test our products. Foundry, assembly and test capacity is currently limited due to a spike in semiconductor demand. None of our third-
party foundry, assembly or test subcontractors have provided assurances that adequate capacity will be available to us.

Inflation and inflationary pressures could have an adverse effect on our business, financial condition, results of operations and cash flows.

Similar to most companies, we are exposed to risks from fluctuations in inflation. In particular, increasing or high inflation rates could adversely

affect our business by increasing the cost of raw materials, energy, labor and transportation of goods. Current or future efforts by governments in
locations where we operate to stimulate the economy may increase the risk of significant inflation. In the event of an increase in rates of inflation, we
may seek to increase the sales prices of our solutions in order to maintain satisfactory profits. Such increases in prices may not be accepted by our
customers and may not be sufficient to compensate us for the negative impact of inflation. Inflation might also reduce disposable income on a macro
basis, eroding savings values, which could affect the demand for products that contain our solutions. If we are not able to offset the effects of increased
inflation, it could have a negative effect on our business, financial condition, results of operations and cash flows.

We are subject to order and shipment uncertainties and our results of operations could be materially adversely affected if we are unable to
accurately forecast customer demand.

We have limited sales visibility as our customers typically do not provide us with firm, long-term purchase commitments. Additionally, our
customers may also have limited sales visibility because of the rapidly changing nature of the global economy, NAND supply and demand dynamics and
the markets in which devices using our products are sold.

Substantially all of our sales are made on a purchase order basis, which permits our customers to cancel, change or delay their product purchase

commitments with little or no notice to us and often without penalty to them, which limits our ability to accurately forecast sales and maintain adequate
inventory levels, manufacturing capacity and operating infrastructure requirements. Our customers, most of whom are NAND flash makers and module
makers, face difficulties in predicting demand for their storage devices using our products, which could result in the procurement forecast provided to us
changing at short notice. The majority of our customers are building storage devices such as SSDs used in PCs and other client devices and embedded
MultiMediaCard (“eMMC”) and universal flash storage (“UFS”) mobile embedded storage used primarily in smartphones and other smart devices and
are dependent on original equipment manufacturers (“OEMs”) of these devices accurately anticipating end-consumer demand, which has historically
been difficult and subject to unpredictable deviations from past sales patterns. Also, since a significant portion of our quarterly sales, especially from
module maker customers targeting channel markets, are from orders received and fulfilled in that quarter, our visibility as to expected orders from these
customers in subsequent periods and for any extended period of time is limited. The multiple layers of forecasts from other customers and from their
customers may introduce other errors into our estimates of anticipated sales.

To ensure the availability of our products for our customers, we generally instruct our foundries to begin manufacturing our products based on

forecasts provided by these customers in advance of receiving purchase orders. However, these forecasts do not represent binding purchase
commitments, and sales of our products are only recognized when they are shipped with ownership transferred to the customer. As a result, we incur
inventory and manufacturing costs in advance of anticipated revenue. Because demand for our products may not materialize, manufacturing based on
forecasts subjects us to risks of high inventory carrying costs and increased obsolescence and may increase our costs. If we overestimate customer
demand for our products or if purchase

10

 
orders are cancelled or shipments delayed, we may end up with excess or obsolete inventory, which could have a material and adverse effect on our
financial results. The risk of obsolescence and/or excess inventory is heightened for devices designed for consumer electronics due to short product
lifecycles for these types of products. Conversely, if we underestimate demand or if insufficient manufacturing capacity is available, we may not have
sufficient product inventory, which could lead to missed revenue opportunities, loss of market share, damages to our customer relationships and other
harm to our business. In addition, any future significant cancellations or deferrals of product orders or the return of previously sold products could
materially and adversely affect our profit margins, increase product obsolescence and restrict our ability to fund our operations.

Because many of our expenses are fixed in the short term or are incurred in advance of anticipated sales, we may not be able to decrease our

expenses in a timely manner to offset any shortfall of sales, or expand our R&D and other operating infrastructure in a timely manner to capture
anticipated business opportunities. If we expand our business operations and demand for our products does not increase as we may have projected, our
operating results could be affected by our higher operating expense levels. Conversely, if we maintain or reduce our business operations and related
expenses in accordance with our projections and demand for our products increases more than expected, our operating results could be affected by lost
business opportunities, less competitive economies of scale, and damaged relationships with our customers.

The demand for our products depends in part on the market conditions in the industries into which they are sold. Fluctuations in demand for our
products or a market decline in any of these industries could have a material adverse effect on our results of operations.

Industry-wide fluctuations in the PC and smartphone markets could have a materially adverse effect on our operating results. A large portion of

our controller sales are for the PC and smartphone markets, both of which are mature and have experienced flat-to-declining sales trends because of
market saturation and longer replacement cycles. Changes in demand for devices have been more volatile during since the start of the Covid-19
pandemic, with periods of strong demand and periods of weak demand. As the pandemic abates, there is no assurance that supply-demand volatility will
also abate.

We have benefitted and should continue to benefit from technological changes in PCs and other client devices and in smartphones and tablets,

such as the replacement of hard disk drives (“HDDs”) with SSDs in PCs and other client devices and the replacement of eMMC with UFS mobile
embedded storage in smartphones and tablets. When a significant majority of PCs and client devices have adopted SSDs and smartphones and tablets
have adopted UFS, we expect growth in demand for controllers for client SSDs and UFS will decelerate and stop. Smartphones and tablets have in
recent years cannibalized the sale of PCs and it is possible smartphones and tablets could be replaced by other types of mobile computing and
communications devices, and these changes could also lead to unfavorable demand for our products.

The market for storage devices using NAND flash components has experienced rapid technological changes, could be subject to industry
consolidation and could face competition from new technologies. NAND flash technology will continue to evolve rapidly with continued cost
reductions, which could lead to new types of solid state storage devices, new applications and new categories of customers and market segments where
we could be comparatively disadvantaged. The market for solid state storage devices is relatively fragmented with many suppliers that include NAND
flash makers, module makers and OEMs, and if the market were to consolidate, a trend experienced by other parts of the semiconductor and storage
industries, we could face changing demand for our products, replacement of our products by those of our competitors or internal captive sources and
reduced market opportunities. If solid state storage devices were to use other types of non-volatile memory technologies other than NAND flash and we
do not have relevant and competitive controller technology, our addressable market for controllers could shrink.

The market for controllers is composed of the merchant market and captive market. We are an independent merchant supplier of controllers to

NAND flash maker, module maker and OEM customers. All of the major

11

 
NAND flash makers also have internal captive sources of controllers. The merchant market for controllers could shrink if the NAND flash makers were
to expand their usage of captive sources of controllers. In the past, our operating results were negatively affected when NAND flash customers chose to
insource controllers.

The COVID-19 pandemic continues to impact our business and could materially adversely affect our financial condition and results of
operations.

Our business has been, and will continue to be, adversely impacted by the effects of the ongoing COVID-19 pandemic. The degree to which
COVID-19, and variants of COVID-19, impacts our results of operations will depend on future developments, which are highly uncertain and cannot be
predicted, including, but not limited to, the duration and severity of the pandemic, the actions taken to contain the virus or treat its impact including the
ongoing roll out of vaccinations and vaccine boosters, other actions taken by governments, businesses and individuals in response to the virus and
resulting economic disruption and how quickly and to what extent normal economic and operating conditions can resume in each geographic location
we conduct business in. We are similarly unable to predict the extent of the impact of the pandemic on our customers and suppliers and their financial
conditions, but a material effect on them could also materially adversely affect us.

The pandemic has resulted in governments imposing and businesses implementing numerous measures to try to contain the virus, such as travel

bans and restrictions, quarantines, shelter-in-place, social distancing and shutdowns. These measures have impacted and may further impact our
workforce and operations, the operations of our customers and suppliers, including third-party manufacturers and supply chain, and our ability to
conduct business with both our customers and suppliers.

The pandemic has caused us to modify our business practices, including limiting or restricting employee travel, enforcing work-from-home and
social distancing and canceling physical meetings, events, and conferences. We may take further actions as required by government authorities, or that
we determine are in the best interests of our employees, customers and suppliers. Work-from-home and other measures introduce additional operational
risks, including cybersecurity risks, and have affected the way we conduct our product development, validation and qualification, business development,
sales and customer support, as well as other activities, which could have a material adverse effect on our operations. There is no certainty that such
measures will be sufficient to mitigate the risks posed by the virus, and illness and workforce disruptions could lead to unavailability of key personnel
and harm our ability to perform critical functions.

The pandemic has significantly increased economic and demand uncertainty. It has caused a significant contraction in the global economy, and

there is considerable uncertainty as to the severity and duration of the contraction and the timing and strength of an economic recovery. Given the
continued and substantial economic uncertainty and volatility created by the pandemic, it is more difficult than normal to forecast demand for our
products. In addition, the impacts of the COVID-19 pandemic will be exacerbated the longer the pandemic continues and makes it challenging for us to
estimate the future performance of our business.

While some governments have recently eased some of the restrictions put in place, the emergence of new variants could cause further restrictions

to be put in place.

We may pursue acquisitions, investments and dispositions, which could adversely affect our results of operations.

Our growth strategy includes the acquisition of, and investment in, businesses that offer complementary products, services and technologies,

augment our market coverage, or enhance our technological capabilities. Our past acquisitions include Shannon Systems in 2015 and Bigtera in 2017.
Our investments include Kinara (previously known as Deep Vision, Inc.) in 2018, 2020 and 2021 and BIWIN Storage Technology Corp. (referred to
herein as “BIWIN”) in 2021. We may not be able to identify suitable acquisition or investment opportunities, or to consummate any such transactions. In
addition, our original estimates and assumptions used in assessing

12

 
any transaction may be inaccurate and we may not realize the expected financial or strategic benefits of any such transaction.

Any acquisition we may undertake involves risks and uncertainties, such as unexpected delays, challenges and related expenses, and the

associated diversion of management’s attention. We may become subject to legal proceedings relating to the acquisition and the integration of acquired
businesses may not be successful. The integration of an acquired business involves significant challenges, including, among others: potential disruption
of our business, diversion of management’s attention from daily operations and the pursuit of other opportunities, incurring significant restructuring
charges and amortization expense, assuming liabilities and ongoing lawsuits, potential impairment of acquired goodwill and other intangible assets,
increasing our expenses and working capital requirements, and implementing our management information systems, operating systems and internal
controls for the acquired operations. In addition, our due diligence process may fail to identify significant issues with the acquired company’s products,
financial disclosures, accounting practices, legal, tax and other contingencies and compliance with local laws and regulations. These difficulties may be
complicated by factors such as the size of the business or entity acquired, geographic and cultural differences, lack of experience operating in the
industry or geographic markets of the acquired business, potential loss of key employees and customers, the potential for deficiencies in internal controls
at the acquired or combined business, performance problems with the acquired business’ technology, exposure to unanticipated liabilities of the acquired
business, insufficient revenue to offset increased expenses associated with the acquisition, adverse tax consequences and our potential inability to
achieve the growth prospects or synergies expected from any such acquisition. Failure to manage and successfully integrate the acquisitions we make, or
to improve sales and margins of the acquired businesses, could materially harm our business, operating results and margins.

Any future acquisitions we make may require debt or equity financing, which, in the case of debt financing, would increase our leverage and
interest expenses, and in the case of equity financing, would be dilutive to our existing stockholders. Acquisitions made with cash would reduce our cash
reserves.

From time to time, we may also seek to divest or wind down portions of our business, either acquired or otherwise, or we may exit investments,

each of which could materially affect our cash flows and results of operations. In addition, any such disposition could result in disruptions to other parts
of our business, potential loss of employees or customers, or exposure to unanticipated liabilities or ongoing obligations to us following any such
disposition. For example, in connection with such disposition, we may enter into transition services agreements or agree to provide certain indemnities
to the purchaser, which may result in additional expenses and may adversely affect our financial condition and results of operations.

We depend on a few large customers for a significant portion of our revenues and a loss of some of these customers would result in the loss of a
significant portion of our revenues.

We derived a substantial portion of our revenue from sales to a relatively small number of customers. As a result, the loss of any significant

customer could materially and adversely affect our financial condition and results of operations. Sales to our five largest customers represented
approximately 56%, 65% and 67% of our net revenue in 2020, 2021 and 2022, respectively. Sales to our significant customers represented 24%, 36%
and 45% of our net revenue in 2020, 2021 and 2022, respectively. In 2020, the significant customer was Micron. In 2021, the significant customers were
Intel and Micron and in 2022, were Micron and SK Hynix. The identities of our largest customers and their respective contributions to our net revenue
have varied and will likely continue to vary from period to period.

We expect that we will continue to depend on a relatively limited number of customers for a substantial portion of our net sales and our ability to

maintain good relationships with these customers will be important to the ongoing success of our business. We cannot assure you that revenues
generated from these customers, individually or in the aggregate, will reach or exceed historical levels in any future period. Our failure to meet the
demands of these customers could lead to cancellation or reduction of businesses from these customers. In

13

 
addition, any loss, cancellation or reduction of businesses from, significant change in scheduled deliveries to, or decrease in the prices of products sold
to any of these customers could significantly reduce our revenues and adversely affect our financial condition and operating results. Moreover, any
difficulty in collecting outstanding amounts due from our customers particularly customers who place large orders, would harm our financial
performance. In addition, if our relationships with our largest customers are disrupted for any reason, it could have a significant impact on our business.

NAND industry cyclicality could adversely affect our growth and profitability.

The NAND industry is highly capital intensive and regularly experiences cycles of shortages and excess supply and related rapid increases and

sharp decreases in NAND component prices. The price of solid state storage devices, such as SSDs and eMMC and UFS devices, in which NAND
accounts for a significant portion of material cost, could also rise and fall with NAND component prices. Falling prices for solid state storage devices
could trigger stronger market demand for these devices as well as controllers used in them, and conversely, rising prices for solid state storage devices
could cause demand for these devices as well as controllers used in them to fall, which could negatively affect our sales and profitability.

Additionally, during periods of NAND shortage, our sales and profitability could be negatively affected in other ways, including, but are not
limited to: (i) our module maker and OEM storage customers may not be able to procure sufficient supplies of NAND components, which could lead to
reduced demand for our controllers; (ii) we may not be able to procure sufficient supplies of NAND components for our Shannon data center SSDs and
Ferri industrial SSDs, which could lead to reduced sales of our SSD solutions, and furthermore, to higher cost of procured NAND components and
reduced SSD solutions profitability; (iii) NAND manufacturers may divert NAND supply away from their own storage products that use our controllers
towards other customers or products that do not use our controllers, and our sales could be reduced.

During periods of NAND excess supply when NAND prices are falling sharply, our sales and profitability could also be negatively affected,

including, but are not limited to: (i) NAND manufacturers facing reduced demand for NAND components and storage devices may temporarily build
NAND inventory instead of selling at lower prices, and this may cause a reduction in controller demand; (ii) module maker customers that are exposed
to volatile NAND pricing conditions may temporarily become more cautious in procuring NAND components, which could lead to reduced levels of
controller procurement and storage device production; (iii) OEMs may temporarily limit procurement of storage devices in expectation of procuring
more at a later date and at a lower price, which could restrain storage device and associated controller procurement; and (iv) NAND vendor and module
maker customers that are under margin pressure because of falling NAND prices may seek price concessions from their controller suppliers.

If we fail to accurately anticipate and respond to market trends or fail to develop and introduce new or enhanced products to address these trends
on a timely basis, our ability to attract and retain customers could be impaired and our competitive position could be harmed.

Our success depends to a significant extent on the development, qualification, implementation and acceptance of new product designs and

improvements that provide value to our customers. Our ability to develop, qualify and distribute, and have manufactured, new products and related
technologies to meet evolving industry requirements, at prices acceptable to our customers and on a timely basis are significant factors in determining
our competitiveness in our target markets. For example, for our products addressing the SSD market, we must successfully identify customer
requirements and design, develop and produce products on time that compete effectively as to price, functionality and performance. We sell products in
markets that are characterized by rapid technological change, evolving industry standards, frequent new product introductions, smaller process
geometries and other factors. We cannot assure you that our efforts to execute our product roadmap will result in innovative products and technologies
that provide value to our customers. If we fail to or are delayed in developing, qualifying or shipping new products or technologies that provide value to
our customers and address

14

 
these new trends and adjust our business accordingly, we may lose competitive positioning, which could cause us to lose market share and require us to
discount the selling prices of our products. Although we make substantial investments in research and development, we cannot be certain that we will be
able to develop and successfully bring to market new products and technologies on a timely basis or that they will be well-received by our customers.
Moreover, our investments in new products and technologies involve certain risks and uncertainties and could disrupt our ongoing business. New
investments may not generate sufficient revenue, may incur unanticipated liabilities and may divert our limited resources and distract management from
our current operations. We cannot be certain that our ongoing investments in new products and technologies will be successful, will meet our
expectations and will not adversely affect our reputation, financial condition and operating results.

We believe that our future success depends on our ability to develop and introduce new technologies and products for new applications to generate

new sources of revenue to replace, or build upon, existing product revenue for applications that are mature or in secular decline. If we are not able to
repeatedly introduce, in successive years, new products for new applications that ship in volume, our revenue will likely not grow and may decline
significantly and rapidly. In the past, we were able to successfully grow our revenue by adding over time successive categories of new controller
technologies for new applications, such as memory card and flash drive controllers for external storage, eMMC and UFS mobile embedded memory
controllers for smartphones and SSD controllers for PCs and other client devices. If we are unable to successfully expand our sales of SSD controllers
for data center and enterprise applications, our prospects for continued revenue growth could be adversely affected.

Our gross margin and results of operations may be adversely affected in the future by a number of factors, including decreases in average selling
prices of products over time and shifts in our product mix.

Our gross margin is highly dependent on product mix, especially the mix of higher gross margin controller sales and lower gross margin SSD
solutions sales. A shift in sales mix away from our higher margin products could adversely affect our gross profitability as a percentage of sales and
could also adversely affect our operating profitability. The primary elements of our controller cost of sales are IC fabrication at our foundries, assembly
and testing, and in contrast, the primary cost of sales of our SSD solutions, which are primarily our Shannon data center SSDs and Ferri industrial SSDs,
is NAND flash components. Our SSD solutions gross margin is lower than our controller gross margin because these products are generally less
differentiated and we have limited ability to mark-up the cost of NAND flash components that we procure.

The controllers we develop and sell are used for high volume applications and their average selling prices have historically decreased over time,

and we believe that it is possible they may also fall in the future. We may experience period-to-period fluctuations in future operating results if our
average selling prices decline. We may be forced to reduce the average unit price of our products in response to new product introductions by our
competitors, competitive pricing pressures and other factors. Also, we often provide large customers with volume-related, price-discount incentives
relating to their orders of specific products; if customer procurements that benefit from these incentives scale significantly, they could lead to downward
pressure on our gross margins. The mobile and computing devices markets are extremely competitive, which may result in rapidly declining average
selling prices of electronic devices and components, such as those made by us, and create downward pressure on our average selling prices and
operating results. To maintain acceptable operating results, we will need to develop and introduce new products and product enhancements on a timely
basis and continue to reduce our costs. If we are unable to offset any reductions in our average selling prices by increasing our sales volumes or reducing
corresponding production costs or if we fail to develop and introduce new products and enhancements on a timely basis, our sales and operating results
will be materially and adversely affected.

We have changed our commercial arrangement with a few of our SSD solutions customers to a NAND consignment arrangement, where our
customers procure and maintain ownership of the NAND flash components used in the SSD solutions that we design and build for them, and the gross
margins of these types of sales are

15

 
higher than the sales of products where we are responsible for procuring NAND flash components. We cannot assure you that in the future, we can
increase the proportion of SSD solutions sales using a NAND consignment arrangement and if more sales are conducted using a NAND consignment
arrangement, that it would lead to improvements in our operating results.

Our SSD solutions product performance could continue to adversely affect our results of operations.

We are primarily a fabless semiconductor company focused on NAND flash controllers and the sales of these controllers account for a significant

majority of our overall sales. In addition, we also sell SSD solutions, mostly Ferri industrial SSDs and Shannon enterprise SSDs, but also Bigtera
software-defined storage solutions and appliances. We introduced our Ferri products in 2011, acquired Shannon in 2015 for US$45.6 million, acquired
Bigtera in 2017 for US$4.7 million and are developing our FlashGo all-flash array storage solution. Both our Shannon and Bigtera acquisitions have not
met financial expectations to date, have been dilutive to our gross margins, operating margins and earnings per ADS, and led to US$16.0 million and
US$17.5 million write-downs of Shannon goodwill and intangible assets in 2019 and 2020, respectively, US$4.1 million write-down of Bigtera goodwill
and intangible assets in 2018. We cannot provide assurance that in the future, we will be able to sell our Shannon and Bigtera products profitably or if
we will incur further write downs of inventories. If we are able to expand the sales of our SSD solutions, we cannot provide assurance that expanded
sales of these products will not negatively affect our gross margin and operating margin, which could negatively affect the market price of our
ADSs. Furthermore, even if we are able to sell our SSD solutions to customers profitably, our return on invested capital for SSD solutions will likely be
materially lower than our corporate average primarily because of lower product profitability and higher investments, mainly for working capital
necessary for financing NAND and other inventory, and this could negatively affect our overall financial return and the market price of our ADSs.

Our SSD solutions are modules, software and appliances, which are different from our primary controller products, which are integrated circuits

and have different financial characteristics. Our SSD solutions gross margin is materially lower than our controller gross margin because these products
are generally less differentiated and, in the case of our Ferri and Shannon SSDs, where NAND flash components are the majority of their cost of sales,
we have limited ability to mark-up the cost of NAND flash components that we procure. We are also subject to NAND price volatility with our Ferri and
Shannon SSDs; because of rapidly falling NAND prices, we wrote-down US$5.5 million of NAND components and SSDs in inventory in 2020,
US$4.3 million in 2021 and US$8.1 million in 2022. With our Bigtera products, we have had issues with sales returns, with US$2.5 million in 2019. We
cannot assure you that in the future our results of operations will not be negatively affected by further NAND component and SSD inventory write-
downs and Bigtera sales returns.

The loss of any of our key personnel or the failure to attract or retain specialized technical or management personnel could impair our ability to
grow our business.

We rely heavily on the services of our key employees, including Wallace C. Kou, our President and Chief Executive Officer. In addition, our
engineers and other highly skilled personnel are a significant asset and are the source of our technological and product innovations. We believe our
future success will depend upon our ability to attract and retain skilled managerial, engineering and sales and marketing personnel. The competition for
such personnel, particularly engineering personnel, is intense in our industry. We may not be successful in attracting and retaining sufficient numbers of
engineering personnel to support our anticipated growth. These personnel are required to design and develop integrated circuits, including firmware, and
to introduce product enhancements for use in future applications. Despite the incentives we provide, our current employees may not continue to work for
us, and if additional personnel were required for our operations, we may not be able to obtain the services of additional personnel necessary for our
growth. In addition, we do not maintain “key person” life insurance for any of our senior executives or other key employees. The loss of any of our key
employees or our inability to attract or retain qualified personnel, including engineers, could delay the development and introduction of, and have an
adverse effect on our ability to sell, our products as well as have an adverse effect on our overall growth.

16

 
In addition, if any other members of our senior management or any of our other key personnel depart, join a competitor or form a competing company,
we may not be able to replace them easily and we may lose customers, business partners, key professionals and staff members. Substantially all of our
senior executives and key personnel have entered into confidentiality and non-disclosure agreements. In the event of a dispute between any of our senior
executives or key personnel and our operating companies in Taiwan and other foreign countries, we cannot assure you the extent, if any, to which these
provisions may be enforceable in Taiwan or other foreign countries due to the constantly evolving nature of their respective legal systems.

We rely on independent semiconductor foundries and subcontractors for the fabrication, assembly and testing of our integrated circuits, and any
limitation of their available capacity to us or failure to fulfill our orders satisfactorily could damage our relationships with our customers,
decrease our sales or limit our ability to grow our business.

We do not own or operate semiconductor fabrication facilities. Instead, we rely on third parties to manufacture our semiconductors. Two outside

foundries, primarily Taiwan Semiconductor Manufacturing Company (“TSMC”) and secondarily Semiconductor Manufacturing International
Corporation (“SMIC”) fabricate our semiconductors. As a result, we face several significant risks, including wafer cost, availability of wafers and other
raw materials, manufacturing capacity, quality assurance, manufacturing yields and production costs, control over delivery schedules and product
quality, control of our intellectual property, labor availability or strikes and actions taken by third party contractors that breach our agreements.

The ability of each foundry to provide us with semiconductors is limited by its available capacity and access to wafers, and the ability of each

subcontractor to assemble and test our products is limited by available capacity and access to substrates and other raw materials. We do not have long-
term agreements with any of these foundries and subcontractors and we place our orders based on our customers’ purchase orders and sales forecasts.
However, the foundries and subcontractors can allocate capacity to the fabrication, assembly and testing of the products of their other customers and
reduce deliveries to us on short notice or increase the price they charge us. It is possible that other foundry and subcontractor customers that are larger
and better financed than we are, or have long-term agreements with these foundries and subcontractors, may induce these foundries and subcontractors
to reallocate capacity to them which could impair our ability to secure manufacturing, assembly and testing capacity that we need for our products.
Other factors that could materially adversely affect our business and results of operation include, but are not limited to, our foundries and subcontractors
being unable to secure the necessary raw materials from their suppliers, experience power outages, lack sufficient capacity to manufacture our products
or suffer other disruption or reduction in efficiency. If our foundries fail to deliver fabricated silicon wafers of satisfactory quality in the volume and at
the price we require, or if our assembly and testing subcontractors fail to efficiently and accurately assemble and test our products, we will be unable to
meet our customers’ demand for our products or to sell those products at an acceptable profit margin, which would have a material and adverse effect on
our sales and margins and damage our customer relationships.

In addition, interruptions to the wafer manufacturing processes caused by a natural disaster or human error could result in partial or complete
disruption in supply until manufacturing is re-started or we are able to shift manufacturing to another fabrication facility. It may not be possible to obtain
sufficient capacity or comparable production costs at another foundry. Migrating our design methodology to a new third-party foundry could involve
increased costs, resources and development time comparable to a new product development effort. Any reduction in the supply of semiconductors for
our products could significantly delay our ability to ship our products and potentially have negative effects on our relationships with existing customers
and our results of operations. In addition, if our subcontractors terminate their relationships with us, we would be required to qualify new subcontractors,
which could take at least six months, resulting in unforeseen operating problems, and our operating results may be materially and adversely affected.

The manufacture of semiconductors is a highly complex process. Minor deviations in the manufacturing process can cause substantial decreases in

yield. In some situations, such deviations may cause production to be

17

 
suspended. The foundries that manufacture our semiconductors have from time to time experienced lower than anticipated manufacturing yields,
including yields for our semiconductors, typically during the production of new products or architectures or during the installation and start-up and
ramp-up of new process technologies or equipment. If the foundries that manufacture our semiconductors do not achieve planned yields, our product
costs could increase and product availability would decrease.

After the wafer fabrication processes, our wafers are shipped to our assembly and testing subcontractors. We have a system to maximize consistent

product quality, reliability and yield that involves our quality assurance team working closely with subcontractors in the various phases of the assembly
and testing processes. Our supplier quality management includes procedures such as processes to pre-qualify our manufacturing suppliers and
subcontractors. If our subcontractors do not achieve planned product quality, reliability and yield during the assembly and testing processes, our product
cost could increase, product availability could decrease, or our customers may not accept products manufactured for them.

Failure to protect our intellectual properties or maintain the right to certain other technologies may negatively impact our ability to compete.

We believe that the protection of our intellectual property rights and continued access to certain third-party technology are and will continue to be
important to the success of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to
protect our intellectual property rights. We also enter into confidentiality or license agreements with our employees, business partners and other third
parties, and have implemented procedures to control access to and distribution of our documentation and other proprietary information. Despite these
efforts, we cannot assure you that these measures will provide meaningful protection of our intellectual property rights. Further, these agreements do not
prevent others from independently developing technologies that are equivalent to or superior to our technology. In addition, unauthorized parties may
attempt to copy or otherwise obtain and use our proprietary technology. Monitoring unauthorized use of our technology is difficult and we cannot be
certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries such as Taiwan and China where
the laws may not protect our proprietary rights as fully as do the laws of the United States. In addition, if the foundries that manufacture our
semiconductors lose control of our intellectual property, it could be more difficult for us to take remedial measures because our foundries are located in
countries that do not have the same protection for intellectual property that is provided in the United States. Also, some of our contracts, including
license agreements, are subject to termination upon certain types of change-of-control transactions.

As of March 31, 2023, we have 2,490 patents and 1,203 pending applications worldwide. We cannot be certain that patents will be issued as a

result of our pending applications nor can we be certain that any issued patents would protect or benefit us or give us adequate protection from
competing products. For example, issued patents may be circumvented or challenged and declared invalid or unenforceable or provide only limited
protection for our technologies. We also cannot be certain that others will not design around our patented technology, independently develop our
unpatented proprietary technology or develop effective competing technologies on their own.

Failure to successfully defend against intellectual property lawsuits brought against us may adversely affect our business.

Companies in and related to the semiconductor industry often aggressively protect and pursue their intellectual property rights. From time to time,
we have received, and may continue to receive, notices that claim we have infringed upon, misappropriated or misused other parties’ proprietary rights.
Moreover, in the past we have been involved in litigation with parties that claimed that we infringed their patents or misappropriated or misused their
trade secrets. In addition, we or our customers may be sued by other parties that claim that our products have infringed their patents or misappropriated
or misused their trade secrets, or that may seek to invalidate one or more of our patents. An adverse determination in any of these types of disputes could
prevent

18

 
us from manufacturing or selling some of our products, increase our costs of revenue and expose us to significant liability. Any of these claims may
materially and adversely affect our business, financial condition and results of operations. For example, in a patent or trade secret action, a court could
issue a preliminary or permanent injunction that would require us or our customer(s) to withdraw or recall certain products from the market or redesign
certain products offered for sales or under development. We may also be liable for damages for past infringement and royalties for future use of certain
technologies. See “Item 8. Legal Proceedings” below.

In addition, any litigation to defend ourselves against claims that we have infringed the intellectual property rights of others, could, regardless of

the ultimate outcome, materially and adversely affect our operating results by requiring us to incur significant legal expenses and diverting the resources
of the Company and the attention of our management team.

Because the markets in which we compete are highly competitive and many of our competitors have greater resources than we have, we cannot
be certain that our products will compete favorably in the marketplace.

We face competition from a number of competitors, including Marvell and Phison, our flash memory customers and smaller merchant suppliers in

China. We expect to face competition in the future from our current and potential competitors. In addition, some of our flash memory customers could
developed products and technologies that replace their need for our products or otherwise reduce their demand for our products.

Some of our current and potential competitors have longer operating histories, greater name recognition, access to larger customer bases and

significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than we have. As a result, they may be
able to respond more quickly to changing customer demands or to devote greater resources to the development, promotion and sales of their products
than we can. Our current and potential competitors may develop and introduce new products that will be priced lower, provide superior performance or
achieve greater market acceptance than our products. For our SSD solutions, if we are unable to procure sufficient supplies of NAND flash components
and at terms that enable our products to be competitive in terms of price or develop technologically competitive products, our customers may seek to
purchase SSD solutions from other suppliers.

Our products must meet exacting specifications and undetected defects and failures may occur, which may cause customers to return or stop
buying our products and may expose us to product liability risk and risks of indemnification against defects in our products.

Our products are complex and may contain undetected hardware or software defects or failures, especially when first introduced or when new

versions are released. These errors could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from other
important product development efforts and materially affect our customer relations and business reputation. If we deliver products with errors or defects,
our credibility and the market acceptance and sales of our products could be harmed. Defects could also lead to liability for defective products as a result
of lawsuits against us or against our customers. We have agreed to indemnify some of our customers in some circumstances against liability from
defects in our products. A successful warranty or product liability claim could require us to make significant payments.

Our intellectual property indemnification practices may adversely impact our business.

We may be required to indemnify our customers and our third-party intellectual property providers for certain costs and damages of intellectual

property infringement in circumstances where our products are a factor in creating infringement exposure. In the contracts under which we sell
semiconductor products, we may have agreed to indemnify our customers against losses arising out of claims of unauthorized use of intellectual
property. In some of our licensing agreements, we have agreed to indemnify the licensee against losses arising out of or related to our conduct or
services. We cannot assure you that claims for indemnification will not be made or that these claims would not have a material and adverse effect on our
business, operating results or financial condition.

19

 
We are exposed to potential impairment on investments.

We have made investments in equity securities with an aggregate value of approximately US$9.3 million as of December 31, 2022. If the
companies that we invested in are unable to execute their plans and succeed in their respective markets, we may not benefit from such investments, and
we could potentially lose the amounts we invested. We evaluate our investment portfolio on a regular basis to determine if impairments have occurred. If
the operations of any businesses that we have invested decline significantly, we could incur impairment charges that could have a material impact on our
results of operations.

Any failure to achieve and maintain effective internal controls could have a material adverse effect on our business, results of operations and the
market price of our ADSs.

We are subject to reporting obligations under securities laws of the United States. The Securities and Exchange Commission, or the SEC, as
required by Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, adopted rules requiring every public company to include in its
annual report management’s assessment of the effectiveness of the company’s internal controls over financial reporting. In addition, an independent
registered public accounting firm must attest to and report on the effectiveness of the company’s internal controls over financial reporting.

Our management and independent registered public accounting firm have concluded that our internal controls over financial reporting as of

December 31, 2022 are effective. However, we cannot assure you that in the future we or our independent registered public accounting firm will not
identify material weakness during the audit process or for other reasons. In addition, because of the inherent limitations of internal control over financial
reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be
prevented or detected on a timely basis. As a result, if we fail to maintain effective internal controls over financial reporting or should we be unable to
prevent or detect material misstatements due to error or fraud on a timely basis, investors could lose confidence in the reliability of our consolidated
financial statements, which in turn could harm our business and results of operations, negatively impact the market price of our ADSs and harm our
reputation.

We are subject to cybersecurity risks.

We experience cyberattacks of varying degrees on our technology infrastructure and systems and, as a result, unauthorized parties have obtained

in the past, and may in the future obtain, access to our computer systems and networks. The technology infrastructure and systems of our customers,
suppliers, vendors and partners may also experience such attacks. Cyberattacks are external and internal threats that include, but are not limited to,
malware, phishing, advanced persistent threats, denial of service attacks, malicious software downloads, insider security breaches, and hardware and
software vulnerabilities. We believe cyberattack attempts are increasing not only in number also in scope and that perpetrators of cyberattacks continue
to develop increasingly sophisticated systems and means to not only attack systems and damage data, but also evade detection or obscure their activities.

We have controls and policies in place, will continue to review and enhance our capabilities and upgrade our protective solutions to guard against

known and emerging threats, detect malicious or unauthorized activities, and have recovery systems to minimize business disruptions. If efforts to
breach our infrastructure and systems are successful or we are unable to protect against these risks, we could suffer interruptions, delays, or cessation of
operations of our systems, and loss or misuse of proprietary or confidential information, intellectual property, or sensitive or personal information.
Breaches of our infrastructure and systems could also cause our customers and other affected third parties to suffer loss or misuse of proprietary or
confidential information, intellectual property, or sensitive or personal information, and could harm our relationships with customers and other third
parties. As a result, we could experience additional costs, indemnification claims, litigation, and damage to our brand and reputation. All of these
consequences could harm our reputation and our business and materially and adversely affect our operating results and financial condition.

20

 
Our business is subject to various governmental regulations, and compliance with these regulations may cause us to incur significant expense.

We are subject to various state, federal and international laws and regulations governing the environment, including restricting the presence of

certain substances in electronic products. In addition, we are also subject to various industry requirements restricting the presence of certain substances
in electronic products. Although our management systems are designed to maintain compliance, we cannot assure you that we have been or will be at all
times in complete compliance with such laws and regulations. If we violate or fail to comply with any of them, a range of consequences could result,
including fines, import/export restrictions, sales limitations, criminal and civil liabilities or other sanctions.

Recently there has been increased focus on environmental protection and social responsibility initiatives, which are subject to change, can be

unpredictable, and may be difficult for us to comply with, given the complexity of our supply chain and our significant outsourced manufacturing. We
are required to implement various standards or processes due to the adoption of rules or regulations that result from these initiatives, such as the SEC
rules on the disclosure of the use of “conflict minerals.” If we are unable to comply, or ensure that our suppliers or contract manufacturers comply, with
such standards or processes, customers may stop purchasing from us, which could adversely affect our sales and results of operations.

Our business is subject to various other international laws and other legal requirements, including packaging, product content, labor and
international trade regulations, such as the U.S. Export Administration Regulations and sanctions against Huawei and other companies, and applicable
executive orders. These laws, regulations and orders are complex, change frequently and with limited notice, have generally become more stringent over
time and have intensified as U.S.-China geopolitical tensions worsen. Although we have policies, controls, and procedures designed to help ensure
compliance with applicable laws, there can be no assurance that our employees, contractors, suppliers, or agents will not violate such laws or our
policies. Any such violations of trade laws, restrictions, or regulations can result in fines; criminal sanctions against us or our officers, directors, or
employees; prohibitions on the conduct of our business; and damage to our reputation. We may be required to incur significant expense to comply with,
or to remedy violations of, these regulations and laws. In addition, if our customers fail to comply with these regulations and laws, we may be required
to suspend sales to these customers, which could damage our reputation and negatively impact our results of operations. The technology industry is
subject to intense media, political, and regulatory scrutiny, which can increase our exposure to government investigations, legal actions, and penalties.

Our stock price has been, and may continue to be, volatile, which could result in investors losing all or part of their investments.

Since we completed our initial public offering in June 2005, the market price of our ADSs has been and likely will continue to be highly volatile

and could be subject to wide fluctuations in response to numerous factors, including but are not limited to the following:

•

•

•

•

•

•

•

  actual or anticipated variations in our quarterly operating results or those of our competitors, customers, or NAND flash vendors;

  actual or anticipated changes in NAND flash supply and demand dynamics;

  actual or anticipated changes in our market share or the market share of our competitors;

  the commencement or results of litigation;

  short selling or market manipulation activities;

  announcements by us, our competitors, our customers, or their other suppliers of new products or technological innovations;

  changes in financial estimates or recommendations by securities analysts;

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

  economic and social effects of the COVID-19 virus and the emergence of additional variants to the COVID-19 virus or other pandemics;

  the payment or non-payment of cash dividends at the discretion of our board of directors;

  the announcement and implementation of share repurchase programs;

  announcements by us or our competitors of significant acquisitions, divestitures or partnerships; and

  actual or anticipated changes in the global economic or industry outlook.

Many of these factors are beyond our control and may negatively impact the market price of our ADSs, regardless of our performance. In addition,

the stock market in general, and the market for technology and semiconductor companies in particular, have been highly volatile. Furthermore, the
trading price of our ADSs may be adversely affected by third-parties trying to drive down the market price. Short sellers and others, some of whom post
anonymously on social media, may be positioned to profit if our stock declines and their activities can negatively affect our stock price. These broad
market and industry factors may seriously harm the market price of our ADSs, regardless of our operating performance. Our ADSs may not trade at the
same price levels as that of other semiconductor and technology companies, and shares of semiconductor and technology companies, in general, may not
sustain their current market prices. These fluctuations as well as general economic, political, and market conditions may have an adverse effect on the
market price of our ADSs.

There can be no assurance that we will declare cash dividends in the future in any particular amounts or at all.

In January 2013, our Board of Directors declared our first quarterly cash dividend and has subsequently declared and paid dividends in each

successive quarter. In November 2015, our Board changed the dividend declaration from quarterly to annually, with payments made in four quarterly
installments. Pursuant to the terms of the Merger Agreement, during the period prior to the closing of the Merger, we are not permitted to declare, set
aside, make or pay any dividend or other distribution other than the remaining quarterly dividends previously declared in October 2021 (the last of
which was paid in August 2022). In the event the Merger Agreement is terminated, the decision to declare dividends in the future, if any, and their
timing and amount, will depend on, among other things, that the dividend payment is in the best interests of our shareholders, business visibility, our
results of operations, capital availability and future capital requirements, financial condition, statutory requirements, and other factors that the Board
may deem relevant and any dividend declaration is at the discretion of our Board. Any future dividend payments may change from time to time, and we
cannot provide assurance that we will in the future declare dividends, if at all or in any particular amounts. A reduction in or elimination of our dividend
payments could have a negative effect on our share price.

If we are characterized as a passive foreign investment company, U.S. holders of our ADSs may experience adverse tax consequences.

Based on the present and projected composition of our income and valuation of our assets, we believe we are not currently classified as a passive

foreign investment company (“PFIC”) for U.S. federal income tax purposes. We will generally be classified as a PFIC for any taxable year in which
either (a) at least 75% of our gross income is passive income or (b) at least 50% of the value (determined on the basis of a quarterly average) of our
assets is attributable to assets that produce or are held for the production of passive income. If we are characterized as a PFIC, U.S. holders of our ADSs
may experience adverse tax consequences. See “ITEM 10. ADDITIONAL INFORMATION — Taxation — United States Federal Income Taxation.”

Our business, financial condition and results of operations could be adversely impacted by the political and economic conditions of the countries
in which we conduct business and operate.

A substantial portion of our business is conducted outside of the United States and, as a result, we are subject to foreign business, political and

economic risks. Most of our integrated circuits are manufactured,

22

 
 
 
 
 
 
 
 
 
 
assembled and tested by third-parties located in China and Taiwan. We generated 92%, 94% and 86% of our revenue in 2020, 2021 and 2022,
respectively, from sales to customers outside the United States, and for the year ended December 31, 2022, 58% of our revenue was from sales in
three jurisdictions, China, Singapore and Taiwan. Our controller research and development is conducted primarily in Taiwan and our SSD solutions
research and development is conducted in both China and Taiwan. Most of our corporate functions are located in Taiwan. These operations are directly
influenced by the political and economic conditions of the country in which they are located. We do not expect the portion of our business located
outside of the United States to change in the future.

Accordingly, we are subject to risks associated with international operations, including but not limited to:

•

•

•

•

•

•

•

•

•

•

  international economic and political conditions, such as political tensions between countries in which we do business (please also refer to

Risk Factors relating to China and Taiwan);

  unexpected changes in, or impositions of, legislative or regulatory requirements;

  complying with a variety of foreign laws;

  differing legal standards with respect to protection of intellectual property and employment practices;

  cultural differences in the conduct of business;

  inadequate local infrastructure that could result in business disruptions;

  trade issues related to export or import restrictions, tariffs, quotas and other trade barriers and restrictions, including those related to the

ongoing trade disputes between China and the U.S.;

  financial risks such as longer payment cycles and difficulty in collecting accounts receivable;

  adverse taxes rules, regulations and penalties; and

  other factors beyond our control such as nature disasters, terrorism, civil unrest, war, including Russia’s ongoing invasion of Ukraine, and

health emergencies, such as COVID-19.

As a result of having global operations, the sudden disruption of our supply chain and/or disruption of the manufacture of our customer’s products

caused by events outside of our control could impact our results of operations by impairing our ability to timely and efficiently deliver our products.

Although our reporting currency is the U.S. dollar, and the majority of our sales and cost of sales in the last three years are denominated in the

U.S. dollar, the majority of our operating expenses are denominated in the NT dollar, and to a lesser extent, the Chinese yuan and U.S. dollar. Any
unfavorable changes in foreign exchange rates could adversely affect, or cause fluctuations in, our results of operations. We do not currently engage in
currency hedging activities.

We operate primarily in regions that are susceptible to natural disasters.

We operate primarily in regions of the world, including Taiwan, China and California, that are susceptible to earthquakes. In the past, these
regions had experienced severe earthquakes that caused significant property damage and loss of life, although we did not suffer any material impact on
our business. The occurrence of earthquakes is unpredictable, and a major earthquake and consequent disruptive events could severely disrupt the
normal operations of our business and have a material and adverse effect on our financial condition and operating results.

We face substantial risks associated with doing business in Taiwan because of tense regional geopolitical risk with China.

Most of our business operations are in Taiwan, a self-governing democracy, with a unique international political status, that is claimed by China

and receives security from the United States under the Taiwan Relations

23

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Act. China asserts that Taiwan is part of China, seeks the unification of Taiwan and has not ruled out the use of force to achieve this. China is also
increasingly assertive in the region and claims sovereignty over much of the South China Sea south of Taiwan and has unilaterally established an Air
Defense Identification Zone, or ADIZ, in the East China Sea north of Taiwan. The United States does not recognize China’s ADIZ and conducts regular
freedom of navigation operations in the areas claimed by China. In 2016, China dismissed the United Nation’s Permanent Court of Arbitration ruling
against it in its claims to the South China Sea. Tensions between Taiwan and China and between the United States and China have increased in recent
years.

A majority of our employees and a significant portion of our research and development and corporate functions are based in Taiwan. We also

operate a research and development center in Shanghai, and China is one of the largest markets for our products. In addition, all of our foundries and
assembly and testing subcontractors are located in either Taiwan or China. Accordingly, our business and results of operations and the market price of
our ADSs may be affected by any deterioration in the relationship between Taiwan and China. Although there are significant economic ties between
Taiwan and China, in recent years China has taken a more aggressive posture towards Taiwan, including the suspension of cross-straits communications
channels in 1996, regular intrusion by Chinese military aircraft into Taiwan airspace, the sailing of naval ships around Taiwan waters, the conduct of
military exercises close to Taiwan, and exclusion of Taiwan from international organizations such as the World Health Organization.

Furthermore, our principle executive offices are in Hong Kong. Previous pro-democracy protests and recent COVID-19 containment activities

have affected our Hong Kong operations and China’s new national security law for Hong Kong has reduced its autonomy and could lead to further
repercussions from the United States, Taiwan and other countries that more adversely affect our operating arrangements, whether commercial or
regulatory in nature.

Past and recent developments in relations between Taiwan and China have on occasion depressed the market prices of the securities of Taiwanese
companies or companies with significant business activities in Taiwan. We cannot assure you that any contentious situation between Taiwan and China
will always resolve in maintaining the current status quo or remain peaceful. Relations between Taiwan and China, potential confrontations between the
United States and China and other factors affecting military, political, social or economic conditions in Taiwan and Hong Kong could have a material
adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our ADSs.

The enactment of legislation implementing changes in the taxation of international business activities, the adoption of other tax reform policies
or changes in tax legislation or policies could materially impact our financial position and results of operations.

Legislation is introduced from time to time to reform the taxation of international business activities. The Organisation for Economic Co-operation

and Development, or OECD, has released guidance covering various topics, including country-by-country reporting, definitional changes to permanent
establishment and guidelines in determining arm’s length transfer pricing. This guidance is collectively referred to as Base Erosion and Profit Shifting,
or BEPS, an initiative that aims to standardize and modernize global tax policy. Depending on legislation ultimately enacted in connection with this
guidance by jurisdictions in which we operate, there may be significant consequences for us due to our large international business activities. For
example, adoption of BEPS by foreign jurisdictions in which we operate could result in changes to tax policies, including transfer-pricing policies that
could ultimately impact our tax liabilities to foreign jurisdictions. If any of these proposals are enacted into law, or if other international, consensus-
based tax policies and principles are amended or implemented, they could have material adverse consequences on the amount of tax we pay and thereby
on our financial position and results of operations. It is likely that new legislation enacted by several governments of countries in which we operate
could lead to higher operating and tax expenses for our business in the near future.

We are subject to risks associated with development and construction of our office buildings.

In September 2018, we purchased 65,700 square feet of land in Hsinchu, Taiwan for a total cost of US$58.9 million and expect to spend an
estimated US$77 million for the development and construction of our future Hsinchu headquarters building, which is currently targeted for completion
in 2024. On February 18, 2021, the Company won a bid with a third-party to build an office building in Taipei, Taiwan and executed a property
development agreement in May 2021, with property development costs to be defined and agreed in a subsequent agreement. We have no experience
developing and constructing office buildings and managing real property of this scale. We may encounter unanticipated occurrences or conditions during
construction that may increase the expense of these projects. We may also encounter unanticipated delays in the construction of the new buildings and
local government approvals for the projects may be delayed. We will also be required to comply with applicable environmental regulations in connection
with such development. We are financing these construction projects from our cash balance, which could limit alternative deployments of capital. The
purchase of the land and construction of the buildings will increase our fixed assets significantly and could reduce our return on invested capital. After
the office buildings have been constructed, we may consider sale and leaseback arrangements if favorable terms can be obtained.

We focus primarily on designing, developing and marketing: (i) NAND flash controllers for solid state storage devices, primarily SSDs used in

PCs and other client devices and eMMC and UFS mobile embedded storage used in smartphones and IoT devices and (ii) SSD solutions, primarily
small form-factor specialized SSDs used in industrial, commercial and automotive applications. In 2020, 50% to 60% of our net sales were of SSD
controllers, 25% to 30% were eMMC and UFS controllers and 10% to 15% were SSD solutions. In 2021, 55% to 60% of our net sales were of SSD
controllers, 30% to 35% were eMMC and UFS controllers and 5% to 10% were SSD solutions. In 2022, 45% to 50% of our net sales were of SSD
controllers, 35% to 40% were eMMC and UFS controllers and 5% to 10% were SSD solutions.

NAND Flash Controllers

We offer a broad range of controllers for developing different categories of solid state storage devices that are used in a wide variety of

applications. We provide controllers for computing-grade SSDs used in PCs and other client devices, enterprise-grade SSDs used in data centers, eMMC
and UFS mobile embedded storage used in smartphones and IoT devices, flash memory cards and flash drives used as expandable storage and
specialized SSDs used in industrial, commercial and automotive applications. For most of these applications we offer customers controllers, which are
designed for a range of different price-performance trade-offs that enable the targeting of different market segments, such as value-line, mainstream and
premium. Our controllers are a combination of integrated circuits and firmware and are offered as configurable platforms or turnkey solutions, which
provide customers with options to customize products to achieve desired differentiation or focus on fast time-to-market. Since SSDs and mobile
embedded storage products are defined by continuously evolving industry standards such those relating to, but are not limited to, the PCIe host interface,
NVMe data transfer protocol and UFS storage specification, we provide controllers for the latest versions of these industry standards and design our
solutions for customers to build storage devices with competitive product performance and compatibility with host devices. Our controllers are also
designed to support the majority of the latest next generations of NAND flash components manufactured by vendors such as Kioxia, Micron, Samsung,
SK Hynix and its subsidiary Solidigm, Western Digital and YMTC, which enables customers to have wide choices of components for developing and
building storage devices. Controllers integrate technologies that are critical to their functionality and these include advanced error correction codes
(“ECC”) and digital signal processing (“DSP”) engines for ensuring data reliability and sophisticated wear-leveling algorithms for maximizing the
usable life of NAND flash components. We may also incorporate other technologies in our controllers such as encryption, power-loss protection,
multimedia digital rights management and active temperature monitoring.

SSD Solutions

We use our unique controller technology to develop Ferri SSD solutions. Our FerriSSDs, Ferri-eMMCs, and Ferri-UFS products are highly

reliable industrial-, commercial- and automotive-grade single-chip SSDs, which

26

 
 
are developed for a wide-range of embedded applications that require high data rate, small form factor and compliance with industry standards. We offer
customers firmware customization for performance tuning as a value-added service.

Our Customers

We sell our products to NAND flash makers, module makers, hyperscalers and OEMs worldwide. Most of our high performance flash memory
storage controllers are supplied to NAND flash manufacturers. We are a leading supplier of SSD controllers used in data centers, PCs, automotive and
other client devices and a leading merchant supplier of eMMC and UFS controllers used in smartphones and IoT devices. Sales to our five largest
customers represented approximately 56%, 65% and 67% of our net revenue in 2020, 2021 and 2022, respectively. Sales to our significant customers
representing 24%, 36% and 45% of our net revenue in 2020, 2021 and 2022, respectively. In 2020, the significant customer was Micron. In 2021, the
significant customers were Intel and Micron and in 2022, were Micron and SK Hynix. The identities of our largest customers and their respective
contributions to our net revenue have varied and will likely continue to vary from period to period.

The majority of our customers purchase our products through purchase orders, as opposed to entering into long-term contracts with us. The price

for our products is typically agreed upon at the time a purchase order is placed.

Sales and Marketing

We market and sell our products worldwide through a combination of direct sales personnel and independent electronics distributors. Our direct

sales personnel are strategically located near our NAND flash manufacturer, leading technology OEM and modular maker customers in Taiwan, Korea,
China, the United States, and Japan. Approximately 70% of our sales in 2020, 67% of our sales in 2021, and 79% of our sales in 2022 were attributable
to our direct sales force while the remainder was attributable to distributors.

To supplement our direct sales, we have independent electronics distributors and sales reps located throughout the world. We selected these

distributors and reps based on their ability to provide effective field sales, marketing communications and technical support for our products to our
customers.

Our marketing group focuses on our product strategy, product development road maps, new product introduction process, demand assessment,

competitive analysis and product marketing. We seek to work with potential and existing customers early in their design process to best match our
products to their needs, and more broadly, to ensure that product development activities, product launches, and on-going demand and supply planning
occur in a well-managed, timely basis in coordination with our research and development, operations, and sales groups, as well as our customers and
distributors. We also attend industry tradeshows and technical conferences to promote our products and solutions, maintain close contact with our
existing customers to assess demand, and keep current with industry trends. Our participation in industry standards associations, such as IEEE, JEDEC,
NVM Express, and Open Compute Project (OCP) helps us monitor the latest industry developments and promote our corporate profile. Our marketing
group also works with our sales teams to identify new business opportunities.

We also have field application engineers (“FAEs”), who provide technical support and assistance to existing and potential customers in designing,

testing and qualifying systems that incorporate our products. Our FAE organization is segmented by product and market to support our customers.

Research and Development

Our future success depends on our ability to introduce improvements to our existing products and to develop new products that deliver cost-

effective solutions for both existing and new markets. Our research and

27

 
development efforts are directed largely to both the development of algorithms and other technological building blocks necessary for managing NAND
flash and the use of these technological building blocks to develop a wide variety of NAND flash controller solutions, which are integrated circuits with
embedded firmware, that can manage most available NAND flash components and are used to create different classes of solid state storage devices, such
as enterprise-grade SSDs used in enterprise applications and data centers, client SSDs used in PCs and other client devices, eMMC and UFS embedded
storage for smartphones and IoT devices. We have assembled a core team of engineers who have experience in the areas of firmware, digital and mixed-
signal integrated circuit design and system-level architecture. Our research and development expenses consist primarily of employee salaries and related
benefits including stock-based compensation, tape-out and related project expenses and intellectual property and software licensing costs. We expense
research and development expenditures as they are incurred.

Our primary research and development centers are located in Hsinchu and Taipei, Taiwan, and Shanghai, China. Our facilities in Hsinchu and
Taipei focus primarily on our NAND flash controller products, and our facilities in Shanghai focus primarily on specific product requirements of our
customers in China.

Our research and development activities broaden and strengthen our portfolio of intellectual properties, including patents and trade secrets. As of

March 31, 2023, we have 2,490 patents and 1,203 pending applications worldwide, and we will continue to actively pursue the filing of additional patent
applications in important jurisdictions.

Our research and development expenses were approximately US$121.8 million, US$164.3 million, and US$188.5 million for the years ended

December 31, 2020, 2021 and 2022, respectively.

Manufacturing

We design and develop our products and electronically transfer our proprietary designs to independent foundries for the manufacturing and

processing of silicon wafers. Once the wafers are manufactured, they are then shipped to third-party assembly and testing subcontractors. Individual
integrated circuit dies are diced from wafers, assembled into finished chips and undergo several stages of testing before delivery to our customers. For
certain products, we also ship bare dies to our customers. We believe that our strategy of outsourcing wafer fabrication, packaging and testing enables us
to benefit from the research and development efforts of leading manufacturers without having to commit our own substantial capital investments. Our
fabless business model also provides us with the flexibility to engage vendors who offer services that best complement our products and technologies.

Wafer fabrication. TSMC and SMIC are currently our primary foundries that manufacture most of our semiconductors. We use their fabs in
Taiwan, Singapore, and China to fabricate our devices using CMOS process technology, primarily with process nodes from 16/12 to 55 nanometers. We
regularly evaluate the benefits and feasibility, on a product-by-product basis, of migrating to more cost-efficient manufacturing process technologies.

Assembly and testing. Following wafer fabrication, our wafers are shipped to our assembly and test subcontractors where they are probed,
singulated into individual dies, assembled into packaged chips, and undergo the process of electronic final testing. In order to minimize cost and reduce
turn-around time, our products are designed to use low cost, industry standard packages and can be tested with widely available automatic testing
equipment. We currently engage companies such as SPIL, OSE, Huatian, and KYEC as our primary subcontractors for the assembly and testing of our
products. We have dedicated teams of manufacturing engineers who maintain control over this process from the early stages of manufacturing. Our
engineers work closely with our subcontractors to develop product testing and packaging programs to ensure these programs meet our product
specifications, thereby maintaining our ownership of the functional and parametric performance of our semiconductors.

28

 
Quality and reliability assurance. We have designed and implemented a quality assurance system that provides the framework for continual
improvement of products, processes and customer service. To ensure consistent product quality, reliability and yield, our quality assurance teams
perform reliability engineering, quality control, International Organization for Standardization (ISO) system development, document control,
subcontractor quality management and customer engineering services to closely monitor the overall process from IC design to after-sale customer
support. In particular, we rely on in-depth simulation studies, testing and practical application testing to validate and verify our products. We emphasize
a strong supplier quality management practice in which our manufacturing suppliers and subcontractors are pre-qualified by our quality assurance teams.
Our suppliers are required to have a quality management system, certified to ISO 9000 standard as a minimum requirement. Our operations have been
ISO 9001 certified since 1999.

Competition

We face competition from a number of competitors, including Marvell and Phison, our flash memory customers and small Chinese merchant

controller suppliers.

The markets for our products are intensely competitive, and are characterized by rapid technological change, evolving industry standards, frequent

new product introductions and pricing pressures. Competition has intensified as a result of the increasing demand for higher levels of performance at
competitive prices. We expect competition to intensify further as current competitors continue to strengthen the depth and breadth of their product
offerings and additionally, our competitors in China are benefited from the government’s semiconductor localization policy. We believe that our ability
to compete successfully in the rapidly evolving markets for our products depends on a number of factors, including, but not limited to:

•

•

•

•

•

  the performance, features, quality and price of our products;

  the timing and success of new product introductions by us, our customers and our competitors;

  emergence, rate of adoption and acceptance of new industry standards;

  our ability to obtain adequate foundry capacity at competitive prices; and

  the number and nature of our competitors in specific market sub-segments.

We expect increased competition in the future from emerging or established companies, customers or other third parties, any of which could
acquire significant market share. See “Risk Factors — Because the markets in which we compete are highly competitive and many of our competitors
have greater resources than we have, we cannot be certain that our products will compete favorably in the marketplace,” in Item 3 above.

Seasonality

See “Risk Factors — Our financial conditions and results of operations may vary from quarter to quarter, which may cause the price of our ADSs

to decline.”, “Risk Factors — We are subject to the cyclical nature of the semiconductor industry, which has been subject to significant fluctuations.”
and “Risk Factors — NAND industry cyclicality could adversely affect our growth and profitability.” in Item 3 above and “Operating and Financial
Review and Prospects — Principal Factors Affecting Our Results of Operations” in Item 5 below.

Intellectual Property

Our success and future revenue growth depend, in part, on our ability to protect our intellectual property. We rely on a portfolio of intellectual
property rights, registered in the United States, Taiwan, and other countries, including patents, copyrights and trademark registrations, trade secret laws,
contractual provisions, licenses, and other methods to protect our intellectual property.

29

 
 
 
 
 
 
 
 
 
 
 
As of March 31, 2023, we have 2,490 patents and 1,203 pending applications worldwide. There can be no assurance that patents will ever be
issued with respect to these pending applications. Furthermore, it is possible that any patents held by us may be invalidated, circumvented, challenged or
licensed to others. In addition, there can be no assurance that such patents will provide us with competitive advantages or adequately safeguard our
proprietary rights. While we continue to file new patent applications with respect to our recent developments, existing patents are granted for prescribed
time periods and will expire at various times in the future. We expect to continue to file patent applications where appropriate to protect our proprietary
technologies.

Companies in the semiconductor industry have frequently demonstrated a readiness to commence litigation based on allegations of patent and
other intellectual property infringement. From time to time, third parties may assert infringement claims against us. We may not prevail in any such
litigation or may not be able to license patents from third parties on commercially reasonable terms, if at all. Litigation, regardless of the outcome, is
likely to result in substantial cost and diversion of our resources, including our management’s time. Any such litigation could materially adversely affect
us. In addition, in the contracts under which we sell semiconductor products, we may have agreed to indemnify our customers against losses arising out
of claims of unauthorized use of intellectual property.

We intend to protect our intellectual property rights vigorously, but there can be no assurance that our efforts will be successful. In addition, the

laws of other countries in which our products are sold may not protect our products and intellectual property rights to the same extent as the laws of the
United States.

While our ability to effectively compete depends in large part on our ability to protect our intellectual property, we believe that our technical

expertise, customer support capabilities, and ability to introduce new products in a timely and cost-effective manner will be important factors in
maintaining our competitive position.

We claim copyright and trademark protection for proprietary documentation for our products and a variety of branding marks. We have registered

“Silicon Motion” and its logo (a three-dimensional cube depiction of the letters “SM”), “NANDSustain,” “NANDXtend,” “SSDLifeGuard,”
“SSDLifeSaver,” “TurboMLC,” “FerriSSD,” “Ferri-eMMC,” “Ferri-UFS,” the powered by SiliconMotion logo, “InstantView,” the Shannon Systems
logo, “PCIe-RAID,” “DIRECT-IO,” “Hyper-IO,” “Bigtera,” the Bigtera logo, “VirtualStor,” “CloudStor,” and “StorVisor” as trademarks in the United
States, Taiwan and/or other countries.

We also attempt to protect our trade secrets and other proprietary information through agreements with our customers, suppliers, employees and

consultants, and through other customary security measures.

We have entered into license agreements with third party intellectual property vendors for wafer fabrication tool libraries, semiconductor IP core,

computer aided design tools and software.

Facilities

As of the date of this annual report, we occupy facilities totaling approximately 418,900 square feet, which house our management and
administration, operations, research and development and sales and marketing departments. Of our facilities, approximately 182,400 square feet are
owned and approximately 236,500 square feet are occupied under leases. We consider our facilities insufficient to meet our future operational
requirements and in 2018, purchased 65,700 square feet of land in Hsinchu, Taiwan for the construction of a future office building and in 2021, executed
a property development agreement for the construction of a future office building in Taipei, Taiwan. See “Risk Factor — We are subject to risks
associated with development and construction of our office buildings.” The table below lists the location of our operating facilities.

Summary of Consolidated Financial Results

Summary of the year ended December 31, 2022 include the following:

•

•

•

•

•

•

  Total revenue increased by 3% to US$945.9 million from US$922.1 million in the prior year.

  Gross profit as a percentage of revenue decreased by 0.8% points to 49.2% from 50.0% in the prior year.

  Total operating expenses increased by 17% to US$251.9 million from US$214.9 million in the prior year.

  Operating profit decreased by 13% to US$213.9 million from US$245.9 million in the prior year.

  Income tax expense as a percentage of income before income tax decreased to 18.8% from 19.1% in the prior year.

  Diluted earnings per ADS decreased by 9.6% to US$5.17 from US$5.72 in the prior year.

Principal Factors Affecting Our Results of Operations

Net sales. Our net sales consist primarily of sales of our products, after deducting sales discounts and allowances for returns.

Our net sales are denominated primarily in U.S. dollars. The percentages of our net sales by currency for the periods indicated are set forth in the

following table:

The length of our sales cycle, from the day purchase orders are received until products are shipped to customers, is dependent on the availability

of our product inventories. If we do not have sufficient inventories on hand to meet customer demands, approximately three months are generally
required from the day purchase orders are received until finished goods are manufactured and shipped to customers. This cycle can take up to six months
during times when capacity at independent foundries is being fully utilized. The potential delays inherent in the manufacturing process increase the risk
that we may not be able to fulfill a customer’s order on time. All of

32

 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
  
 
 
  
  
 
 
 
 
our sales are made by purchase orders. Because our practice, which is consistent with industry practice, allows customers to reschedule orders on
relatively short notice, order backlog may not be a good indicator of our future sales.

Because most of our semiconductor solutions are designed for the mobile and computing devices markets, we expect our business to be subject to

seasonality, with higher net sales generally in the second half of each year, when customers place orders to meet increased demand during year-end
holiday seasons. However, changing market and business conditions, including foundry wafer supply shortages, as well as changing product mix in
recent years could make assessment of the impact of seasonal factors on our business difficult.

Cost of sales. Our cost of sales consists primarily of the following costs:

•

•

•

•

•

•

  cost of wafer fabrication;

  assembly, testing and shipping costs of our semiconductors;

  personnel and equipment costs associated with manufacturing support;

  quality assurance;

  cost of raw materials; and

  write-down of inventory.

We engage independent foundries for the manufacturing and subcontractors for the assembly and testing of our semiconductors. Our

manufacturing cost is subject to the cyclical supply and demand conditions typical of the semiconductor industry. Our cost per wafer generally fluctuates
with the availability of capacity at independent foundries. We believe that our cost of sales is substantially variable in nature.

Research and development expenses. Our research and development expenses consist primarily of employee salaries and related costs, stock-based

compensation, tape-out and related project expenses and intellectual property and software licensing costs. We expense research and development
expenditures as they are incurred.

Sales and marketing expenses. Our sales and marketing expenses consist primarily of employee salaries and related costs, stock-based

compensation expense, commissions paid to independent distributors and costs for our advertising and promotional activities.

General and administrative expenses. Our general and administrative expenses consist primarily of employee salaries and related costs, stock-

based compensation expense, insurance premiums, professional fees and allowance for doubtful accounts.

Impairment of goodwill. We evaluate the recoverability of goodwill annually, or sooner if events or changes in circumstances indicate that the

carrying amount may not be recoverable.

Accounting for stock-based compensation. We grant restricted stock units to our employees and members of the Board of Directors. The value of
our restricted stock units is expensed over the vesting period and based on the grant date share price, less the present value of expected dividends during
the vesting period, discounted at a risk-free interest rate.

Non-operating income and expenses. Our non-operating income and expenses include loss from the disposal of a subsidiary, gains or losses on the
sales of investments, unrealized holding gain on investment, interest from deposited cash or short-term investments, gains or losses on foreign exchange
rates, interest paid on loans and other non-operating income and expenses not categorized above. We conduct an assessment on the value of our long-
term investments quarterly and make corresponding write-downs as required to the value of the long-term investments.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
Provision for income taxes. We must make certain estimates and judgments in determining income tax expenses for financial statement purposes.
These estimates and judgments occur in the calculation of tax credits, benefits, deductions and allowance, and in the calculation of certain tax assets and
liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes, as well as the
interest and penalties related to uncertain tax positions.

We have operations in several countries, which include Taiwan, China, Hong Kong, Macau and the United States and determine income taxes for

each of the jurisdictions where we operate.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have

been prepared in accordance with accounting principles generally accepted in the United States.

The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amount of assets,

liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. We base our estimates and judgments on our historical
experience, knowledge of current conditions and our beliefs of what could occur in the future considering available information. Because our estimates
may vary in each situation, our actual results may differ from our estimates under different assumptions and conditions.

Our management considers the following factors in reviewing our consolidated financial statements:

•

•

  the selection of critical accounting policies; and

  the judgments and other uncertainties affecting the application of those critical accounting policies.

The selection of critical accounting policies, the judgments and other uncertainties affecting the application of those policies and the sensitivity of

reported results to changes in conditions and assumptions are factors to be considered when reviewing our consolidated financial statements. Our
principal accounting policies are set forth in detail in Note 2 to our consolidated financial statements included elsewhere in this annual report.

Critical accounting estimates are defined as those reflective of significant judgments, estimates and uncertainties, which may result in materially

different results under different assumptions and conditions. We believe the following are our critical accounting estimates:

Inventory valuation. We value inventories at the lower of cost or net realizable value for raw materials, work-in-process and finished goods.
Inventories are recorded at standard cost and adjusted to the approximate weighted-average cost at the balance sheet date. We assess net realizable value
of the inventory for estimated obsolescence or unmarketable inventory based upon management’s assumptions about future demand and market
conditions. In estimating reserves for obsolescence, we primarily evaluate estimates based on the timing of the introduction of new products and the
quantities remaining of old products and provides reserves for inventory on hand in excess of the estimated demand. Estimated losses on slow-moving
items are recognized and included in the allowance for losses. We wrote down US$6.9million, US$5.7 million and US$15.8 million in 2020, 2021 and
2022, respectively, for estimated obsolete or unmarketable inventory, with write-downs in 2020, 2021 and 2022 primarily related to the value of NAND
components and SSDs in inventory affected by rapidly falling NAND prices and the restructuring of our underperforming product lines.

We have not made any material changes in the accounting methodology used to evaluate obsolescence or unmarketable inventory during the last
three fiscal years. However, if actual results are not consistent with our estimates and assumptions used to calculate inventory write-downs, we may be
exposed to inventory write-downs that could be material. If we have experienced significant industry fluctuations, maturing product cycles and new
product introductions of both semiconductor companies’ and their customers’ products and fluctuations in general economic conditions, we may be
exposed to future obsolescence or unmarketable inventory.

Goodwill. We record goodwill when the consideration paid for an acquisition exceeds the fair value of net tangible and intangible assets acquired.

We measure and test goodwill on an annual basis or more frequently if we believe indicators of impairment exist. Our impairment review process
compares the fair value of the reporting unit in which the goodwill resides to its carrying value. We determined that our reporting units are equivalent to
our operating segments or components of an operating segment for the purposes of completing our impairment test. We have adopted FASB Accounting
Standard Update 2017-04, which removed step two from the goodwill impairment test, in conjunction with our annual review for impairment.
Estimating fair value is performed by utilizing various valuation approaches, such as income approach or market approach. The total of all reporting unit
fair values was also compared to our market capitalization plus control premium for reasonableness.

In 2020, we recorded an impairment charge of US$17.5 million related to our Shannon acquisition. The worse than expected business outlook and

lower cash flow projections of these reporting units led to reductions in their fair market value and the assessment of impairment charges for the
difference of carrying value in excess of fair market value. The estimate of cash flow was based upon, among other things, certain assumptions about
expected future operating performance such as revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted
discount rates, future economic and market conditions, and determination of appropriate market comparable. We based our fair value estimates on
assumptions we believed to be reasonable but that are unpredictable and inherently uncertain. The long-term financial forecast represented the best
estimate that we had at that time and we believed that its underlying assumptions were reasonable.

Accounting for income taxes. In preparing our consolidated financial statements, we are required to estimate our income taxes in each of the
jurisdictions in which we operate. We are tax residents in numerous taxing jurisdictions around the world and have identified our major tax jurisdictions
as Taiwan, Hong Kong, Macau and China with statutory tax rates of 20%, 16.5%, 12% and 25%, respectively, and estimate our actual current tax
exposure together with assessed temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences
result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our
deferred tax assets will be recovered from future taxable income within the relevant jurisdiction and, to the extent we believe that recovery is not likely,
we must establish a valuation allowance. The total amount of valuation allowance as of December 31, 2020, 2021 and 2022 was US$20.8 million,
US$21.8 million and US$20.2 million, respectively. We provide for a valuation allowance to the extent we believe that it is more likely than not that the
deferred tax assets will not be recovered from future taxable income. Realization of future tax benefits related to the deferred tax assets is dependent on
many factors, including our ability to generate taxable income within the period during which the temporary differences reverse, the outlook for the
economic environment in which we operate, and the overall future industry outlook. Should we determine that we would not be able to realize all or part
of our net deferred tax asset in the future, an additional allowance for the deferred tax asset would be charged to income in the period the determination
was made.

We utilize a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition

by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of
related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being
realized upon ultimate settlement. The total amount of unrecognized tax benefits as of December 31, 2020, 2021 and 2022 was US$19.0 million,
US$26.3 million and US$37.1 million, respectively. As of December 31, 2021 and 2022, US$6.4 million and US$6.8 million, respectively, of interest
and penalties were accrued. Fiscal years 2017 through 2022 remain subject to examination by the US Internal Revenue Service and other foreign tax
jurisdictions. The ultimate outcome of tax matters may differ from our estimates and assumptions. Unfavorable settlement of any particular issue would
require the use of cash and could result in increased income tax expense. Favorable resolution could result in reduced income tax expense. Within the
next

35

 
12 months, we do not expect that our unrecognized tax benefits would change significantly. See Note 13 to the consolidated financial statements for
further information regarding changes in unrecognized tax benefits during 2022.

Legal Contingencies. From time to time, we are involved in legal actions or other third-party assertions arising in the ordinary course of business.

There can be no assurance these actions or other third-party assertions will be resolved without costly litigation, in a manner that does not adversely
impact our financial position, results of operations or cash flows or without requiring royalty payments in the future, which may adversely impact gross
margins. We record a liability when it is probable that a loss has been incurred and the amount can be reasonably estimated. In determining the
probability of a loss and consequently, determining a reasonable estimate, management is required to use significant judgment. Given the uncertainties
associated with any litigation, the actual outcome can be different than our estimates and could adversely affect our results of operations, financial
position and cash flows. See Item 8: “Legal Proceedings”.

In 2022, our net sales increased by 3% year-over-year to approximately US$945.9 million. Our Mobile Storage revenue increased by 2% year-
over-year primarily because of increasing sales of eMMC and UFS controllers. Our SSD controller sales decreased in the range of 5% to 10% year-over-
year to account for 45% to 50% of revenue, a lower percentage of net sales than the prior year, eMMC plus UFS controller sales increased in the range
of 15% to 20% year-over-year to account for 35% to 40% of revenue, a higher percentage of net sales than the prior year, and SSD solutions sales
increased in the range of 30% to 35% year-over-year to account for 5% to 10% of revenue, a similar percentage of net sales as the prior year.

Unrealized holding gain on investment. We recognized a gain of US$896 thousand for the difference between market value and cost of long-term

investments in 2022.

Interest income. Our interest income increased to approximately US$2.7 million for the year ended December 31, 2022 from approximately

US$1.3 million for the year ended December 31, 2021.

Interest expense. Interest expense increased to US$71 thousand for the year ended December 31, 2022 from nil for the year ended December 31,

2021.

Foreign exchange gain (loss), net. For the year ended December 31, 2022, we realized a foreign exchange loss of US$4,880 thousand, compared

with a gain of US$193 thousand for the year ended December 31, 2021. We do not engage in any hedging activities.

Income tax expense (benefit). Income tax expense was approximately US$40.1 million for the year ended December 31, 2022 compared to an

income tax expense of approximately US$47.3 million for the year ended December 31, 2021.

Net income (loss). Net income was approximately US$172.5 million for the year ended December 31, 2022 compared to a net income of

approximately US$200.0 million for the year ended December 31, 2021.

For the discussion covering the comparison between the years ended December 31, 2021 and 2020, please refer to “Item 5” of our annual report

on Form 20-F for the year ended December 31, 2021 filed with the SEC.

Liquidity and Capital Resources

As of December 31, 2022, we had approximately US$232.2 million in cash and cash equivalents, a decrease of US$127.9 million from
December 31, 2021. We maintain our cash balances in bank deposits and in money market instruments. We do not engage in any currency hedging
activities.

We believe cash we expect to generate from operating activities will be sufficient to meet our anticipated working capital needs, capital

expenditures, and other commitments for at least the next 12 months. Our future capital requirements will depend on many factors, including the level of
our net sales, the timing and extent of spending to support product development efforts, the expansion of sales and marketing activities, the timing of
introductions of new products, the costs to ensure access to adequate manufacturing capacity, the continuing market acceptance of our products, and
construction of our Hsinchu and Taipei office buildings. We could be required, or could elect, to seek additional funding through public or private equity
or debt financing, and additional funds may not be available on terms acceptable to us or at all.

Capital Return to Shareholders

per ADS, we paid US$54.0 million and US$49.9 million to shareholders

40

 
 
 
 
 
 
 
 
 
in 2021 and 2022, respectively. Pursuant to the terms of the Merger Agreement, during the period prior to the closing of the Merger, we are not
permitted to declare, set aside, make or pay any dividend or other distribution other than the remaining quarterly dividends previously declared in
October 2021 (the last of which was paid in August 2022).

If the Merger Agreement is terminated, the declaration and payment of future cash dividends are subject to our Board’s continuing determination
that the payment of dividends is in the best interests of our shareholders and is in compliance with all laws and agreements applicable to the declaration
and payment of cash dividends.

Share Repurchase. On December 7, 2021, our Board of Directors authorized a new share repurchase program to repurchase up to US$200 million

of our ADSs over a 6-month period. In the year ended December 31, 2022, we repurchased 1.6 million ADSs for US$128.8 million at an average price
of US$79.18 per ADS and in the year ended December 31, 2021, we repurchased 0.6 million ADSs for US$50 million at an average price of US$89.87
per ADS. Our previous share repurchase program, announced on November 21, 2018 and which authorized the repurchase of up to US$200 million of
our ADSs over a 24-month period was extend on October 26, 2020 for an additional year. In the year ended December 31, 2020, we repurchased
0.6 million ADSs for US$25.0 million at an average price of US$39.93 per ADS, in the year ended December 31, 2019, we repurchased 0.8 million
ADSs for US$25.0 million at an average price of US$32.82 per ADS, and in the year ended December 31, 2018, we repurchased 1.0 million ADSs for
US$34.8 million at an average price of US$34.54 per ADS.

Repurchases are made in the open market or according to other methods in compliance with Securities and Exchange Commission Rule 10b-18,

subject to market conditions, applicable legal requirements and other factors. Share repurchase plans announced do not obligate us to acquire any
particular amount of ADSs and may be suspended at any time at our discretion.

Cash Requirements

Our material cash requirements include the following contractual and other obligations:

Pension Obligations. Pension obligations represent the payments for deferred compensation plan liabilities, see Note 12 Pension Plan in our

consolidated financial statements. As of December 31, 2022, these obligations totaled US$0.2 million. Pension obligation after one year has not been
estimated.

Operating Leases. Operating lease obligations represent the undiscounted remaining lease payments primarily for our leased property and
equipment, see Note 16 Lease in our consolidated financial statements. As of December 31, 2022, these obligations totaled US$8.4 million, of which
US$3.3 million was short-term.

Office Building Construction. We won a bid with a third-party to build an office building in Taipei and entered into a property development

agreement in May 2021. Based on the terms of the property development agreement, the Company is required to complete construction within three
years after the construction license is approved. At this time, we are unable to accurately measure the construction progress and make a reasonably
reliable estimate of the timing and future payments to the contractor, see Note 17 Commitments and Contingencies in our consolidated financial
statements.

Tax Liability. Tax liability represents the provision for income tax and uncertain tax position recognized, see Note 13 Income Taxes. As of

December 31, 2022, short-term taxes payable totaled US$42.1 million. We increased long-term taxes payable of US$10.8 million related to uncertain tax
positions as of December 31, 2022. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years
beyond 12 months due to uncertainties in the timing and outcome of a potential tax audit.

Board Practices

Board Committees

Our board of directors has established an audit committee, a compensation committee, and a nominating and corporate governance committee.

Audit Committee. The audit committee is responsible for reviewing the financial information that will be provided to shareholders and others,

reviewing the systems of internal controls that management and the board of directors have established, appointing, retaining and overseeing the
performance of independent registered public accounting firms, overseeing our accounting and financial reporting processes and the audits of our
consolidated financial statements, and pre-approving audit and permissible non-audit services provided by independent registered public accounting
firms. Tsung-Ming Chung, Lien-Chun Liu, and Yung-Chien Wang are members of our audit committee. Our board of directors has determined that
Mr. Chung, the Chairman of the audit committee, is the committee’s “Audit Committee Financial Expert” as required by Nasdaq and the U.S. Securities
and Exchange Commission (“SEC”) rules.

Compensation Committee. The compensation committee’s basic responsibility is to review the performance and development of management in
achieving corporate goals and objectives and to assure that our senior executives are compensated effectively in a manner consistent with our strategy,
competitive practice and the requirements of the appropriate regulatory bodies. Toward that end, this committee oversees, reviews and administers all of
our compensation, equity and employee benefit plans and programs. Lien-Chun Liu, Steve Chen, and Yung-Chien Wang are members of our
compensation committee, with Mr. Chen serving as the Chairman of the committee.

Nominating and Corporate Governance Committee. The nominating and corporate governance committee is responsible for overseeing, reviewing
and making periodic recommendations concerning our corporate governance policies, and for recommending to the full board of directors candidates for
election to the board of directors. Lien-Chun Liu, Steve Chen, and Yung-Chien Wang are members of our nominating and corporate governance
committee, with Ms. Liu serving as the Chairman of the committee.

Our board of directors has adopted a code of ethics, which is applicable to all of our employees. Our Code of Ethics is posted on our website at

www.siliconmotion.com.

Duties of Directors

Under Cayman Islands law, our directors have a duty to act honestly, in good faith and with a view to the best interests of our company. Our

directors also have a duty to exercise the care, diligence and skills that a reasonably prudent person would exercise in comparable circumstances. In
fulfilling their duty of care to our company, our directors must ensure compliance with our memorandum and articles of association. The functions and
powers of our board of directors include, among others:

•

  exercising any other powers conferred by the shareholders’ meetings or under our amended and restated memorandum and articles of

association.

Terms of Directors and Officers

Under Cayman Islands law and our articles of association, our directors hold office until a successor has been duly elected and qualified. Our

articles of association provide that our directors serve for a term of three years, with one-third of the directors (or, if their number is not a multiple of
three, the number nearest to but not greater than one-third) subject to re-election at each annual general meeting of shareholders (chairman and
managing director not subject to retirement by rotation nor to be taken into account in determining the number of directors to retire), unless the director

director is eligible for re-election. One of our seven directors is currently subject to re-election at our next annual general meeting of shareholders. All of
our executive officers are appointed by and serve at the discretion of our board of directors.

Limitation on Liability and Other Indemnification Matters

Cayman Islands law and our articles of association allow us to indemnify our directors, secretary and other officers acting in relation to any of our
affairs against actions, costs, charges, losses, damages and expenses incurred by reason of any act done or omitted in the execution of their duties as our

any fraud, dishonesty, willful misconduct or bad faith which may attach to any of them.

Compensation of Directors and Executive Officers

For the year ended December 31, 2022, the aggregate compensation to our directors and senior executive officers was approximately

US$5.85 million. In 2022, we granted restricted stock units to our directors and executive officers as a group to acquire an aggregate of 69,600 ordinary
shares. The restricted stock units granted to our executive officers and non-executive directors are subject to the same vesting conditions as those of our
employees.

Service Contracts

We currently do not have service contracts with our directors.

Share-Based Compensation Plans and Option Grants

On June 3, 2015, the board of directors adopted the 2015 Incentive Plan (the “2015 Plan”). The 2015 Plan reserved 20,000,000 ordinary shares for

issuance upon exercise of stock options and restricted stock units. The Plans provide for the grant of stock options, stock bonuses, restricted stock
awards, restricted stock units and stock appreciation rights, which may be granted to our employees (including officers), directors and consultants.

Share Reserve. The aggregate number of ordinary shares that may be issued pursuant to awards granted under the 2015 Plan will not exceed
20,000,000. Guidelines for Issuance and Subscription of Employee Stock Option, which options we have, subject to the consent of the respective option-
holders, agreed to assume in the share exchange.

The following types of shares issued under the Plans may again become available for the grant of new awards under the Plans: restricted stock

issued under the Plans that is forfeited or repurchased by us prior to it becoming fully vested; shares withheld for taxes; shares tendered to us to pay the
exercise price of an option; and shares subject to awards issued under the Plans that have expired or otherwise terminated without having been exercised
in full.

46

 
 
Administration. The board of directors will administer the Plans and may delegate this authority to administer the plan to a committee. Subject to

the terms of the Plans, the plan administrator, which is our board of directors or its authorized committee, determines recipients, grant dates, the amounts
and types of stock awards to be granted and the terms and conditions of the stock awards, including the period of their exercisability and vesting.
Subject to certain limitations, the plan administrator will also determine the exercise price of options granted, the purchase price for restricted stock and
restricted stock units, and, if applicable, the strike price for stock appreciation rights.

Capitalization adjustments. In the event of a dividend or other distribution (whether in the form of cash, ordinary shares, other securities, or other
property), recapitalization, stock split, reorganization, merger, consolidation, exchange of our ordinary shares or our other securities, or other change in
our corporate structure, the board of directors may adjust the number and class of shares that may be delivered under the Plans and the number, class and
price of the shares covered by each outstanding stock award.

Changes in control. In the event of a change in control of the company, all outstanding options and other awards under the Plans may be assumed,
continued or substituted for by any surviving or acquiring entity. If the surviving or acquiring entity elects not to assume, continue or substitute for such
awards, the vesting of such awards held by award holders whose service with us or any of our affiliates has not terminated will be accelerated and such
awards will be fully vested and exercisable immediately prior to the consummation of such transaction, and the stock awards shall automatically
terminate upon consummation of such transaction if not exercised prior to such event.

Future amendments and termination. The board of directors may amend (subject to shareholder approval if required by applicable law), suspend

or terminate the 2015 Plan at any time. The 2015 Plan will terminate pursuant to its terms on June 3, 2025.

Legal Proceedings

As an active operating company, we are subject to legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course

of business. Although the outcome of such proceedings and claims cannot be predicted with certainty, management does not believe that the outcome of
any of these matters will have a material adverse effect on our business, results of operations, financial position or cash flows. Any litigation, however,
involves potential risk and potentially significant litigation costs, and therefore there can be no assurance that any litigation which is now pending or
which may arise in the future would not have such material adverse effect on our business, financial position, results of operations or cash flows. On
April 5, 2022, we were named as defendant in a patent infringement lawsuit was filed against our company by Rampart Asset Management LLC in the
United States District Court for the Eastern District of Texas, Marshall Divisions. The parties entered into a settlement agreement on October 31, 2022,
which included the payment of US$390 thousand to the plaintiff. The amount we paid to Rampart was diligently negotiated and did not have a material
adverse effect on our business, results of operations, financial position or cash flow.

Dividend Policy

See “Item 3. Key Information — D. Risk Factors — Risks Related to our Business — There can be no assurance that we will declare cash

dividends in the future in any particular amounts or at all” of this annual report.

Taxation

United States Federal Income Taxation

The following discussion summarizes certain U.S. federal income tax consequences to a U.S. Holder, as defined below, who purchases our ADSs

and ordinary shares. This discussion assumes that investors will hold their ADSs or ordinary shares as capital assets (generally, property held for
investment). This discussion does not discuss all aspects of U.S. federal income taxation which may be important to particular investors in light of their
individual circumstances, including investors subject to special taxation, such as:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

  banks and financial institutions;

  brokers and dealers in securities or currencies;

  insurance companies;

  tax-exempt organizations and retirement plans;

  grantor trusts;

  S corporations;

  persons holding ADSs or ordinary shares as part of hedging, conversion, constructive sale, straddle or other integrated transactions;

  persons who acquired their ordinary shares upon the exercise of employee stock options or otherwise as compensation;

  persons who have elected the mark-to-market method of accounting;

  persons who own 10% or more of our ADSs or shares;

  real estate investment trusts or regulated investment companies;

  U.S. persons whose “functional currency” is not the U.S. dollar;

  certain former citizens or long-term residents of the United States; and

  Non-U.S. Holders (as defined below).

This discussion is based in part on representations by the depositary and assumes that each obligation under the deposit agreement and any related
agreement will be performed in accordance with its terms. Furthermore, the discussion below is based upon the provisions of the Internal Revenue Code
of 1986, as amended (the “Code”), and U.S. Treasury regulations, rulings and judicial decisions hereunder as of the date hereof. Such authorities are
subject to change, possibly on a retroactive basis, which may result in U.S. federal income tax consequences different from those discussed below.

For a discussion of U.S. federal income tax consequences of the Merger, please see the section entitled “Material U.S. Federal Income Tax

Consequences” in the Merger Proxy Statement.

A person considering an investment in our ADSs or ordinary shares is urged to consult its tax advisor concerning U.S. federal, state, local

and non-U.S. income and other tax consequences.

A U.S. Holder is a beneficial owner of ADSs or ordinary shares that is for U.S. federal income tax purposes:

•

•

•

  a citizen or resident individual of the United States;

  a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States, any state thereof, or the

District of Columbia;

  an estate the income of which is subject to U.S. federal income taxation, regardless of its source; or

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

  a trust if it is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to

control all substantial decisions of the trust or has a valid election in effect under applicable U.S. Treasury regulations to be treated as a
U.S. person.

A beneficial owner of ADSs or ordinary shares that is not a U.S. Holder is referred to herein as a “Non-U.S. Holder.” If a partnership or limited

liability company treated as a partnership for U.S. federal income tax purposes holds ADSs or ordinary shares, the tax treatment of a partner or member
will generally depend on the status of the partner or member and the activities of the partnership or such limited liability company. A partner of a
partnership or a member of such a limited liability company holding ADSs or ordinary shares is urged to consult its tax advisors regarding an investment
in our ADSs or ordinary shares.

ADSs. In general, for U.S. federal income tax purposes, a U.S. Holder of ADSs will be treated as the owner of the underlying ordinary shares that

are represented by such ADSs. Deposits and withdrawals of ordinary shares in exchange for ADSs will not be subject to U.S. federal income taxation.

Distributions on ADSs or ordinary shares. Unless the passive foreign investment company rules, as discussed below, apply, the gross amount of

the distributions in respect of the ADSs or ordinary shares will be subject to tax as dividend income to the extent of our current and accumulated
earnings and profits, as determined under U.S. federal income tax principles. Subject to certain limitations, dividends paid to non-corporate U.S.
Holders, including individuals, may be eligible for a reduced rate of taxation if we are deemed to be a “qualified foreign corporation” for U.S. federal
income tax purposes, provided that such holder satisfies certain holding period requirements with respect to the ownership of our ADSs or ordinary
shares. Subject to the exceptions discussed below, a corporation is a qualified foreign corporation if it is:

•

•

  a foreign corporation that is eligible for the benefits of a comprehensive income tax treaty with the United States that includes an exchange

of information program; or

  a foreign corporation if its stock with respect to which a dividend is paid or its ADSs backed by such stock are readily tradable on an

established securities market within the United States.

The Cayman Islands does not currently have a comprehensive income tax treaty with the United States. A foreign corporation (even if it is
described above) does not constitute a qualified foreign corporation if, for the taxable year in which the dividend is paid or the preceding taxable year,
the foreign corporation is or was a passive foreign investment company. Although we believe that we are a qualified foreign corporation because the
ADSs will be traded on an established U.S. securities market and, as discussed below, we believe that we were not a passive foreign investment
company for our 2022 tax year, no assurance can be given in this regard. In addition, our status as a qualified foreign corporation may change. A U.S.
Holder that exchanges its ADSs for ordinary shares may not be eligible for the reduced rate of taxation on dividends if the ordinary shares are not
deemed to be readily tradable on an established securities market within the United States.

Dividends will be includable in a U.S. Holder’s gross income on the date actually or constructively received by the depositary, in the case of ADSs

or, in the case of ordinary shares, by such U.S. Holder. These dividends will not be eligible for the dividends-received deduction generally allowed to
U.S. corporations in respect of dividends received from other U.S. corporations.

To the extent we pay dividends on the ADSs or ordinary shares in a currency other than the U.S. dollar, the U.S. dollar value of such dividends

should be calculated by reference to the exchange rate prevailing on the date of actual or constructive receipt of the dividend, regardless of whether the
foreign currency is converted into U.S. dollars at that time. If the foreign currency is converted into U.S. dollars on the date of actual or constructive
receipt of such dividends, the tax basis of the U.S. Holder in such foreign currency will be equal to its U.S. dollar value on that date and, as a result, the
U.S. Holder generally should not be required to recognize any foreign currency exchange gain or loss. Dividends paid in respect of the ADSs or ordinary
shares generally will be treated as income from sources outside the United States.

52

 
 
 
 
 
 
To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits, the distribution will first be treated as
a tax-free return of capital, causing a reduction in the adjusted basis of the ADSs or ordinary shares, and the balance in excess of adjusted basis will be
taxed as capital gain.

Sale, exchange or other disposition of ADSs or ordinary shares. Unless the passive foreign investment company rules, as discussed below, apply,

upon the sale, exchange or other disposition of ADSs or ordinary shares a U.S. Holder generally will recognize capital gain or loss equal to the
difference between the amount realized upon the sale, exchange or other disposition and the adjusted tax basis of the U.S. Holder in the ADSs or
ordinary shares. The capital gain or loss generally will be long-term capital gain or loss if, at the time of sale, exchange or other disposition, the U.S.
Holder has held the ADS or ordinary share for more than one year. Net long-term capital gains of non-corporate U.S. Holders, including individuals, are
generally eligible for preferential rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss that a U.S. Holder
recognizes generally will be treated as gain or loss from sources within the United States for U.S. foreign tax credit limitation purposes.

Additional tax on net investment income. An additional 3.8% federal income tax may be assessed on net investment income (including dividends,

other distributions, and gain realized on the sale of ADSs or ordinary shares) earned by certain U.S. Holders. This tax does not apply to U.S. Holders
who hold ADSs or ordinary shares in the ordinary course of certain trades or businesses.

Passive foreign investment company rules. In general, we will be classified as a passive foreign investment company for any taxable year in which

either (a) at least 75% of our gross income is passive income or (b) at least 50% of the value (determined on the basis of a quarterly average) of our
assets is attributable to assets that produce or are held for the production of passive income. For this purpose, passive income generally includes
dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or business and not derived from a related
person), annuities and gains from assets that produce passive income. If we own directly or indirectly at least 25% by value of the equity shares of
another corporation, we will be treated for purposes of the passive foreign investment company tests as owning a proportionate share of the assets of the
other corporation, and as receiving directly a proportionate share of the other corporation’s income.

We believe, based on our present and projected composition of our income and valuation of our assets, we were not classified as a passive foreign

investment company for U.S. federal income tax purposes for our 2022 tax year, although no assurance can be given in this regard. Whether we are a
passive foreign investment company for any particular taxable year is determined on an annual basis and will depend on the composition of our income
and assets, including goodwill. The calculation of goodwill will be based, in part, on the then market value of our capital stock, which is subject to
fluctuation. Accordingly, there can be no assurance that we will not be classified as a passive foreign investment company in the current or any future
taxable year.

If we are a passive foreign investment company for any taxable year during which a U.S. Holder has an equity interest in our company, unless the

U.S. Holder makes a mark-to-market election as discussed below, such U.S. Holder will be subject to special tax rules in any future taxable year
regardless of whether we are classified as a passive foreign investment company in such future years with respect to (a) “excess distributions” and
(b) gain from the disposition of stock. Excess distributions are defined generally as the excess of the amount received with respect to the equity interests
in the taxable year over 125% of the average annual distributions received in the shorter of either the three previous years or a U.S. Holder’s holding
period before the taxable year and must be allocated ratably to each day of the U.S. Holder’s holding period. The amount allocated to the current taxable
year or any year before we became a passive foreign investment company will be included as ordinary income in a U.S. Holder’s gross income for that
year. The amount allocated to other prior taxable years will be taxed as ordinary income at the highest rate in effect for a U.S. Holder in that prior year
and the tax is subject to an interest charge at the rate applicable to deficiencies in income taxes. The entire amount of any gain realized upon the sale or
other disposition of the equity interests will be treated as an excess distribution made in the year of sale or other disposition and as a consequence will be
treated as ordinary income and, to the extent

53

 
allocated to years prior to the year of sale or disposition with respect to which we were a passive foreign investment company, will be subject to the
interest charge described above.

In certain circumstances, instead of being subject to the excess distribution rules discussed above, a U.S. Holder may make an election to include

gain on the ADSs or ordinary shares of a passive foreign investment company as ordinary income under a mark-to-market method, provided that the
ADSs or ordinary shares are regularly traded on a qualified exchange. Under current law, the mark-to-market election is only available for ADSs or
ordinary shares that are regularly traded within the meaning of U.S. Treasury regulations on certain designated U.S. exchanges and foreign exchanges
that meet trading, listing, financial disclosure and other requirements to be treated as a qualified exchange under applicable U.S. Treasury regulations.
The Nasdaq Stock Market is a qualified exchange. The ordinary shares may not be eligible for mark-to-market treatment under the foregoing rule even if
the ADSs otherwise satisfy the applicable requirement.

If a U.S. Holder makes a mark-to-market election, the U.S. Holder will include each year as ordinary income, rather than capital gain, the excess,
if any, of the fair market value of the U.S. Holder’s ADSs or ordinary shares at the end of the taxable year over such U.S. Holder’s adjusted basis in the
ADSs (or ordinary shares, if applicable) and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis of these ADSs or
ordinary shares over their fair market value at the end of the taxable year, but only to the extent of the net amount previously included in income as a
result of the mark-to-market election. A U.S. Holder’s basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts.
Any gain or loss on the sale of the ADSs or ordinary shares will be ordinary income or loss, except that this loss will be ordinary loss only to the extent
of the previously included net mark-to-market gain.

If we are a passive foreign investment company then, under certain circumstances a U.S. Holder must file Internal Revenue Service Form 8621.

A U.S. Holder is urged to consult its tax advisor concerning the U.S. federal income tax consequences of an investment in our ADSs or ordinary

shares if we are or become a passive foreign investment company, including the possibility of making a mark-to-market election.

Information Reporting and Back-up Withholding. The Foreign Account Tax Compliance Act (“FATCA”) generally requires that individuals that
hold certain specified foreign financial assets worth in excess of certain thresholds of $50,000 or more, depending on the individual’s circumstances,
report such ownership to the IRS using IRS Form 8938. The definition of specified foreign financial assets includes not only financial accounts
maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a
non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a
foreign entity. A U.S. Holder may be subject to this reporting requirement unless such holder’s ADSs or ordinary shares are held in an account at a
domestic financial institution. The penalty for failing to file Form 8938 is substantial.

U.S. holders generally are subject to information reporting requirements with respect to dividends on, or proceeds from the disposition of, our
ordinary shares. In addition, a U.S. holder may be subject, under certain circumstances, to backup withholding at a rate of up to 24% with respect to
dividends paid on, or proceeds from the disposition of, our ordinary shares unless the U.S. holder provides proof of an applicable exemption or correct
taxpayer identification number, and otherwise complies with the applicable requirements of the backup withholding rules. A U.S. holder of our ordinary
shares who provides an incorrect taxpayer identification number may be subject to penalties imposed by the IRS. Amounts withheld under the backup
withholding rules are not an additional tax and may be refunded or credited against the U.S. holder’s U.S. federal income tax liability, provided the
required information is timely furnished to the IRS.

Cayman Islands Taxation

The Cayman Islands currently levy no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no

taxation in the nature of inheritance tax or estate duty. There are no other

54

 
taxes likely to be material to our company levied by the Government of the Cayman Islands except for stamp duties that may be applicable on
instruments executed in, or after execution brought within the jurisdiction of, the Cayman Islands. The Cayman Islands are not party to any double
taxation treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands.

We have, pursuant to Section 6 of the Tax Concessions Law (1999 Revision) of the Cayman Islands, obtained an undertaking from the

Governor-in-Council that:

•

•

  no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciation applies to us or

our operations; and

  the aforesaid tax or any tax in the nature of estate duty or inheritance tax are not payable on our ordinary shares, debentures or other

obligations.

The undertaking that we have obtained is for a period of 20 years from March 1, 2005.

In December 2018, the Cayman Islands published The International Tax Co-operation (Economic Substance) Law in response to the OECD’s Base

Erosion and Profit Shifting (BEPS) standards. Silicon Motion Technology Corp. is a Cayman company and may be affected by the new law’s economic
substance requirements, which require companies registered in the Cayman Islands to show business activity in the Caymans, tax residency elsewhere,
or be subject to penalties. Economic substance requirements will apply to existing Cayman companies, such as our company, from July 1, 2019. See
“Risk Factor — The enactment of legislation implementing changes in taxation of international business activities, the adoption of other tax reform
policies or change in tax legislation or policies could materially impact our financial position and results of operations.”

Documents on Display

We have previously filed with the SEC our registration statement on Form F-6 under the Securities Act of 1933, as amended (the “Securities Act”)

with respect to our ADSs.

We are subject to the periodic reporting and other informational requirements of the U.S. Securities Exchange Act of 1934, as amended (the
“Exchange Act”). Under the Exchange Act, we are required to file reports and other information with the SEC. Specifically, we are required to file
annually a Form 20-F no later than four months after the close of each fiscal year, which is December 31. As a foreign private issuer, we are exempt
from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and our officers, directors, and
principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16 of the Exchange Act.

Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the public
reference facilities maintained by the Securities and Exchange Commission at the SEC’s public reference room in Washington D.C. at 100 F Street,
N.E., Room 1580, Washington D.C. 20549. You can request copies of these documents upon payment of a duplicating fee, by writing to the SEC. Please
call the SEC at 1-800-SEC-0330 for further information on the operation of the public reference rooms. The SEC also maintains a Website at
www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the
SEC using its EDGAR system.

ITEM 11.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk. Our exposure to changes in interest rates is limited to interest income generated by our cash deposited with banks and short-term
investments maintained in principal protected notes. We have not entered into any interest rate swap transactions. We do not believe that a 1% change in
interest rates would have a significant impact on our operations.

55

 
 
 
 
 
 
Foreign currency risk. The majority of our revenue, cost of sales, accounts receivable, inventory and accounts payable are denominated in U.S.

dollars. The majority of our operating expense relating to salaries and benefits and accounts payable related to these expenses are denominated in
foreign currencies, primarily the NT dollar. Fluctuations in currency exchange rates could harm our business in the future. We do not utilize foreign
exchange derivatives contracts to protect against changes in foreign exchange rates.

Also refer to “Risk Factors — Our business, financial condition and results of operations could be adversely impacted by the political and

economic conditions of the countries in which we conduct business and operate.”

Investment Risk. We have minority stake equity investments in Cashido, Vastview, Kinara and BIWIN, companies related to the semiconductor

and other technology industries. These investments are accounted for under the cost method because our ownership is less than 20% and we do not have
the ability to exercise significant influence over the operations of these companies. As of December 31, 2022, the aggregate carrying value of
investments on our balance sheet was US$9.3 million. BIWIN was listed to the Science and Technology Innovation Board of Shanghai Stock Exchange
in December 2022 and we had unrealized holding gain US$896 thousand in 2022. We monitor these investments for impairment and make appropriate
reductions in carrying value when an impairment is deemed to be other than temporary. There were no impairments losses for the years ended on
December 31, 2020, 2021 and 2022.

ITEM 12.

DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES

Depositary Fees and Charges. For the year-ended December 31, 2022, our depositary bank owed us a reimbursement of US$0.6 million, net of
withholding tax, for our continuing annual stock exchange listing fees and our other expenses incurred in connection with maintaining and promoting
our ADS program, which was paid in full in January 2023. In addition, the depositary bank has agreed to reimburse us annually for a fixed number of
years for our continuing annual stock exchange listing fees and our other expenses incurred in connection with maintaining and promoting our ADS
program. The amount of annual reimbursements is subject to certain limits.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2022.

Disclosure controls and procedures are designed to ensure that the material financial and non-financial information required to be disclosed in this
annual report on Form 20-F and filed with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules
and forms. The evaluation was performed with the participation of our key corporate senior management, and under the supervision of our Chief
Financial Officer, or CFO, Riyadh Lai, and our President and Chief Executive Officer, or CEO, Wallace Kou. In designing and evaluating the disclosure
controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only
reasonable, rather than absolute, assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment
in evaluating the cost-benefit relationship of possible controls and procedures. Based on the foregoing, our management, including our CEO and CFO,
concluded that our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management, including our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting,
as defined under Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance
with accounting principles generally accepted in the United States. Internal control over financial reporting includes those policies and procedures that:
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets,
(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance
with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with appropriate authorizations;
and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could
have a material effect on the consolidated financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of the end of the period covered by this annual

report based on the criteria set forth in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway Commission (“COSO”). Their assessment included an evaluation of the design of our internal control over financial reporting and testing of
the operational effectiveness of our internal control over financial reporting. Based on that assessment, our management concluded that as of
December 31, 2022, the Company’s internal control over financial reporting was effective.

Deloitte & Touche, the independent registered public accounting firm that audited our consolidated financial statements included in this annual

report has issued an attestation report regarding internal control over financial reporting.

57

 
 
 
 
Changes in Internal Control over Financial Reporting

During 2022, no change to our internal control over financial reporting occurred that has materially affected, or is reasonably likely to materially

affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

All internal control systems no matter how well designed and implemented have inherent limitations. Even systems determined to be effective

may not prevent or detect misstatements or fraud and can only provide reasonable assurance with respect to disclosure and financial statement
presentation and reporting. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changed conditions and the degree of compliance with the policies or procedures may deteriorate.

Attestation Report Of The Independent Registered Public Accounting Firm

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of
Silicon Motion Technology Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Silicon Motion Technology Corporation and subsidiaries (the “Company”) as of

December 31, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
consolidated financial statements as of and for the year ended December 31, 2022, of the Company and our report dated April 28, 2023, expressed an
unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial
Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public
accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain

reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the
design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in
the circumstances. We believe that our audit provides a reasonable basis for our opinion.

58

 
Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any

evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may deteriorate.

because our ADSs are listed on the Nasdaq Global Select Market, we are subject to Nasdaq corporate governance requirements. Nasdaq Listing Rule
5615(a)(3) permits foreign private issuers like us to follow “home country practice” with respect to certain corporate governance matters, such as, for
example, our establishment in 2015 of our 2015 Incentive Plan. We are committed to a high standard of corporate governance. As such, we endeavor to
comply with the Nasdaq corporate governance practices and believe that we are currently in compliance with Nasdaq corporate governance practices
that are applicable to foreign private issuers.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of
Silicon Motion Technology Corporation

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Silicon Motion Technology Corporation and subsidiaries (the “Company”) as

of December 31, 2021 and 2022, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows
for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial
statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of
December 31, 2021 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in
conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control — Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 28, 2023, expressed an
unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the
Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities
and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits
included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures
in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable
basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the consolidated financial statements that was

communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the consolidated
financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does
not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter
below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-2

 
Inventory Valuation — Refer to Notes 2 and 5 to the consolidated financial statements.

Critical Audit Matter Description

The Company’s inventories are stated at the lower of cost or net realizable value. Cost is determined on standard basis and adjusted to the
approximate weighted-average cost at the balance sheet date. The Company adjusts the inventory carrying value to the lower of weighted-average cost
or the estimated net realizable value after completing ongoing reviews of estimated obsolescence or unmarketable inventory based upon the timing of
the introduction of new products and the quantities remaining of old products. Actual product demand may be significantly different than in the past or
forecasted by the Company, which could have a material adverse effect on the Company’s inventories and cost of sales. As of December 31, 2022, the
Company’s net inventory balance was $287,964 thousand.

We identified net realizable value of inventory as a critical audit matter because of significant judgments made by management related to the
forecasted product demand, which includes assumptions about the future market and economic conditions. This required a high degree of auditor’s
judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of net realizable value of inventory.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s net realizable value of inventory included the following, among others:

•

•

•

•

  We obtained an understanding of the Company’s methodology for determining inventory that is obsolete or unmarketable and the key

assumptions and judgments made as part of the process, including the forecasted demand.

  We tested the effectiveness of controls over the review of the provision for obsolete or unmarketable inventories based on the Company’s

methodology, including management’s evaluation of the inventory aging and the forecasted demand.

  We tested the accuracy and completeness of the underlying data management utilized in evaluating inventory aging of the obsolescence

reserve on a sampling basis.

  We evaluated the reasonableness of the Company’s methodology and key assumptions and judgments the Company used to estimate the

net realizable value of inventory by performing the following:

•

•

•

•

•

•

  We compared the inventory level to forecasted product demand, historical sales, and subsequent sales.

  We performed peer analysis and industry analysis to evaluate the reasonableness of the trend of the forecasted product demand.

  We performed corroborating inquiries with the personnel responsible for sales forecasting to evaluate the reasonableness of the

product demand forecasts.

  We made inquiries of various personnel in the Company including, but not limited to, finance and operations personnel about the

expected timing of the introduction of new products.

  We tested the mathematical accuracy of management’s calculations.

  We evaluated whether there is an existence of contradictory evidence based on the information obtained from the Company’s

internal communications to management, press releases, and industry reports, as well as our observations and inquires as to changes
within the business.

Merger Agreement with MaxLinear, Inc.

On May 5, 2022, the Company entered into an Agreement and Plan of Merger, or the Merger Agreement, with MaxLinear Inc. (“MaxLinear”) and

Shark Merger Sub, a wholly-owned subsidiary of MaxLinear, pursuant to which, among other things and subject to the terms and conditions thereof,
MaxLinear agreed to acquire the Company pursuant to a statutory merger under the laws of the Cayman Islands of Shark Merger Sub with and into the
Company, with the Company surviving the merger as a wholly-owned subsidiary of MaxLinear. MaxLinear is a provider of communications systems-
on-chip, or SoC, solutions used in broadband, mobile and wireline infrastructure, data center, and industrial and multi-market applications.

Under the terms of the Merger Agreement, the transaction consideration will consist of US$93.54 in cash and 0.388 shares of MaxLinear common
stock for each American Depositary Share, or ADS, of the Company (other than ADSs representing certain customary excluded shares) and US$23.385
in cash and 0.097 shares of MaxLinear common stock for each ordinary share of the Company not represented by ADSs (other than 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. Upon
closing of the transaction, the current MaxLinear stockholders are expected to own approximately 86% of the combined company and former security
holders of the Company are expected to own approximately 14% of the combined company. Based on the closing price of MaxLinear shares on May 4,
2022, the implied value of the total transaction consideration for the Company is approximately $4.3 billion. Pursuant to the Merger Agreement,
MaxLinear will assume the Company’s vested and unvested employee stock-based compensation awards.

The merger is not subject to any financing conditions but is pending satisfaction of customary closing conditions, including antitrust approval in
the People’s Republic of China. On June 27, 2022, the waiting period under the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976
(the “HSR Act”) expired with respect to the pending merger. If the parties have not closed the merger by June 27, 2023, they will need to re-file under
the HSR Act. On July 13, 2022, MaxLinear’s registration statement on Form S-4, which registered shares of MaxLinear common stock to be issued in
the merger, was declared effective by the SEC. On August 31, 2022, the SMTC security holders approved the merger at an extraordinary general
meeting.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of

America (“U.S. GAAP”). The consolidated financial statements include the accounts of SMTC and its wholly-owned subsidiaries. The Company owns
100% of the outstanding shares in all of its subsidiaries. All significant intercompany balances and transactions have been eliminated upon
consolidation.

F-9

 
Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that

affect certain reported amounts and disclosures. The actual results could differ from those estimates.

Concentration of Credit Risk and Significant Customers

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist principally of cash equivalents and

accounts receivable. Cash and cash equivalents are maintained with high quality financial institutions, the composition and maturities of which are
regularly monitored by management. The Company believes that the concentration of credit risk in its trade receivables is substantially mitigated by the
Company’s credit evaluation process, relatively short collection terms and the high level of credit worthiness of its customers. The Company performs
ongoing credit evaluations of its customers’ financial conditions and limits the amount of credit extended based upon payment history and the
customer’s current credit worthiness. The Company regularly reviews the allowance for bad debt and doubtful accounts or expected losses during the
accounts receivable collection process by considering factors, such as historical write-off and recovery experience, credit quality, age of the accounts
receivable balances and current economic conditions that may affect a customer’s ability to pay. The Company also takes into account reasonable and
supportable forecasts of future conditions when evaluating the adequacy of the allowance for doubtful accounts.

Historically, a relatively small number of customers have accounted for a significant portion of our net revenue. Sales to one customer in 2020,

and two customers in 2021 and 2022 accounted for 10% or more of our net revenue, representing 24%, 36% and 45% of our net revenue in 2020, 2021
and 2022, respectively. In 2020, the significant customer was Micron. In 2021, the significant customers were Intel and Micron and in 2022, were
Micron and SK Hynix. The Company’s top ten customers in 2020, 2021 and 2022 accounted for approximately 71%, 76% and 81% of net sales,
respectively.

Fair Value of Financial Instruments

The carrying amount of the Company’s financial instruments, including cash and cash equivalents, notes and accounts receivable and notes and

accounts payables approximates fair value due to the short-term maturity of the instruments. Long-term investments in listed companies over which we
do not exercise significant influence are recorded at fair value, and any changes in fair value are recognized in net income. Long-term investments in
privately-held companies with no readily determinable market value are recorded using the cost method, since the cost of obtaining verifiable fair value
is unreasonably high. These investments are measured at cost less impairment, if any, plus or minus any changes resulting from observable price
changes in orderly transactions for an identical or similar investment of the same issuer. Any resulting change in carrying amount would be reflected in
net income. The Company’s long-term liabilities approximate their fair values as they contain interest rates that vary according to market interest rates.

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market
participants at the measurement date and in the principal or most advantageous market for that assets or liability. The fair value should be calculated
based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the Company. A three-tier fair
value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value.
The hierarchy prioritizes the inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each
fair value measurement is reported in one of the three levels which is determined by the lowest level input that is significant to the fair value
measurement in its entirety. These levels are:

Level 1 — Use unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Use observable inputs other than Level 1 prices such as quoted prices for identical or similar instruments in markets that are not active,

quoted prices for similar instruments in active markets, and model-

F-10

 
based valuation in which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the
assets or liabilities.

Level 3 — Use inputs that are generally unobservable and reflect the use of significant management judgments and estimates.

Cash Equivalents

The Company considers all highly liquid instruments acquired with a remaining maturity of three months or less when purchased to be cash
equivalents. In addition, time deposits with maturities ranging from more than three months to one year qualify as cash equivalents because they can be
readily converted into known amounts of cash without advance notice with the principal protected and not subject to penalty in an early withdrawal.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is provided based on a review of the collectability of accounts receivables. The Company determines the
amount of allowance for doubtful accounts by examining the historical collection experience, current trends in the credit quality of its customers and its
internal credit policies as well as current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that
may affect a customer’s ability to pay.

Inventories

Inventories are stated at the lower of cost or net realizable value for raw materials, work in process and finished goods. Inventories are recorded at

standard cost and adjusted to the approximate weighted-average cost at the balance sheet date. The Company assesses its net realizable value of the
inventory for estimated obsolescence or unmarketable inventory based upon management’s assumptions about future demand and market conditions. In
estimating reserves for obsolescence, the Company primarily evaluates estimates based on the timing of the introduction of new products and the
quantities remaining of old products and provides reserves for inventory on hand in excess of the estimated demand. Estimated losses on slow-moving
items are recognized and included in the allowance for losses.

Long-term Investments

Investee companies over which the Company had the ability to exercise significant influence but did not have a controlling interest and was the

primary beneficiary were accounted for using the equity method. Significant influence was generally considered to exist when the Company had an
ownership interest in the voting shares of the investee between 20% and 50% and other factors, such as representation in the investee’s board of
directors, voting rights and the impact of commercial arrangements, were considered in determining whether the equity method of accounting was
appropriate. Under this method of accounting, the Company recorded its proportionate share of the net earnings or losses of equity method investees and
a corresponding increase or decrease to the investment balances. The Company evaluated its equity method investments for impairment whenever
events or changes in circumstances indicated that the carrying amounts of such investments might not be recoverable.

Long-term investments in listed companies over which we do not exercise significant influence are recorded at fair value, and any changes in fair

value are recognized in net income. The Company elected to record equity investments of the privately-held companies without readily determinable fair
values and not accounted for by the equity method at cost less impairment and adjusted for subsequent changes in fair value.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Significant additions, renewals and betterments are capitalized, while

maintenance and repairs are expensed as incurred.

Depreciation is computed using the straight-line method over estimated useful lives that range as follows: buildings — 25 to 50 years; machinery

and equipment — 2 to 6 years; furniture and fixtures — 3 to 8 years; software — 1 to 5 years; leasehold and buildings improvement — the shorter of the
estimated useful life or lease

F-11

 
term, which is generally 2 to 6 years. Land is not depreciated. Depreciation expense on property and equipment were approximately
US$13,562 thousand, US$17,160 thousand and US$18,931 thousand for the years ended December 31, 2020, 2021 and 2022, respectively.

Upon the sale or other disposal of property and equipment, the related cost and accumulated depreciation are removed from the accounts, and any

gain or loss is credited or charged to operating income.

Lease

The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at
commencement date based on the present value of lease payments over the lease term. Operating lease ROU assets also include any initial direct costs
and prepayments less lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company
will exercise such options. As the Company’s leases do not provide an implicit rate, the Company uses its collateralized incremental borrowing rate
based on the information available at the lease commencement date, including lease term, in determining the present value of lease payments. Lease
expense for these leases is recognized on a straight line basis over the lease term.

Goodwill

Goodwill is the excess of the purchase price paid over the fair value of the net tangible and intangible assets acquired in a business combination.

Impairment of Goodwill and Long-Lived Assets

The Company evaluates the recoverability of long-lived assets whenever events or changes in circumstances indicate the carrying value may not

be recoverable. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset and its
eventual disposition. The estimate of cash flows is based upon, among other things, certain assumptions about expected future operating performance,
growth rates and other factors. Estimates of undiscounted cash flows may differ from actual cash flows due to, among other things, technological
changes, economic conditions, changes to the business model or changes in operating performance. If the sum of the undiscounted cash flows is less
than the carrying value, an impairment loss is recognized, measured as the amount by which the carrying value exceeds the fair value of the asset. Fair
value is determined by reference to quoted market prices, if available, or discounted cash flows, as appropriate. See Note 8, “Goodwill,” regarding
impairment testing in fiscal year 2020.

The Company monitors the recoverability of goodwill recorded in connection with acquisitions, by reporting unit, annually, or sooner if events or

changes in circumstances indicate that the carrying amount may not be recoverable. The Company conducts its annual impairment test of goodwill on
November 30. Reporting units may be operating segments as a whole or an operation one level below an operating segment, referred to as a component.

Estimating fair value is performed by utilizing various valuation approaches, such as income approach or market approach. The total of all
reporting unit fair values is also compared to the Company’s market capitalization plus control premium for reasonableness. See Note 8, “Goodwill,”
regarding impairment testing.

Other Assets

Other assets primarily consist of deposits for building construction and office leases.

Restricted Assets

Restricted assets consist of restricted cash and cash set aside as collateral for obtaining foundry capacity.

F-12

 
Other long-term liabilities

Other long-term liabilities primarily consist of deposit from construction in progress, noncurrent lease liabilities and unrecognized tax benefit.

Revenue Recognition

The Company recognizes revenue upon transfer of control of promised products or services to customers in an amount that reflects the

consideration the Company expects to receive in exchange for those products or services. Under the revenue recognition standard of Accounting
Standards Codification Topic 606, Revenue from Contracts with Customer (ASC 606), the Company applies the following five-step approach:
(1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the
transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company enters into contracts that may include products that are capable of being distinct and accounted for as separate performance
obligations. To date, the majority of the revenue has been generated by sales associated with products, where a single performance obligation is
identified in general. Revenue from services has been insignificant. Performance obligations associated with product sales transactions are generally
satisfied when control passes to customers upon shipment or the written acceptance of the customers. Accordingly, product revenue is recognized at a
point in time when control of the asset is transferred to the customer. The Company recognizes revenue when it satisfies a performance obligation by
transferring control of a product to a customer in an amount that reflects the consideration to which it is entitled in exchange for those goods. Some of
the Company’s sales are made to distributors and revenue is recognized when control of a product passes to the distributor upon shipment and terms and
payment by the distributor are not contingent on resale of the product.

The Company grants certain distributors limited rights of return and price protection rights on unsold products. The return rights are generally
limited to five percent of the monetary value of products purchased within the preceding six months, provided that the distributor places a corresponding
restocking order of equal or greater value. An allowance for sales returns for distributors and all customers is recorded at the time of sale based on
historical returns information available, management’s judgment and any known factors at the time the financial statements are prepared that would
significantly affect the allowance. Price protection rights are based on the inventory of products the distributors have on hand at the date the price
protection is offered. Actual price adjustments to distributors incurred by the Company have been minimal.

The Company provides warranty for its products. Warranty returns have been infrequent and relate to defective or off-specification parts. The
Company estimates a reserve for warranty based on historical experience and records this amount to cost of sales. For the years ended December 31,
2020, 2021 and 2022, the Company did not experience significant costs associated with warranty returns.

Research and Development

Research and development costs are expensed as incurred. Research and development expense consists primarily of personnel-related expenses,

including stock-based compensation, as well as product masks, IP licensing, design tool and testing costs, equipment depreciation, amortization of
intangible assets and an allocated portion of occupancy costs.

Income Taxes

The provision for income tax represents income tax paid and payable for the current year plus changes in the deferred income tax assets and
liabilities during the years. Deferred income tax assets are recognized for net operating loss carryforwards, research and development credits, and
temporary differences. The Company believes that uncertainty exists regarding the realizability of certain deferred income tax assets and, accordingly,

F-13

 
has established a valuation allowance for those deferred income tax assets to the extent the realizability is not deemed to be more likely than not.
Deferred income tax assets and liabilities are measured using enacted tax rates.

The Company utilizes a two steps approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for

recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained in a dispute with
taxing authorities, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest
amount which is more than 50% likely of being realized upon ultimate settlement. Changes in recognition or measurement are reflected in the period in
which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense.

Foreign Currency Transactions

Foreign currency transactions are recorded at the rates of exchange in effect when the transaction occurs. Gains or losses, resulting from the

application of different foreign exchange rates when cash in foreign currency is converted into the entities’ functional currency, or when foreign
currency receivables and payables are settled, are credited or charged to income in the period of conversion or settlement. At the balance sheet date,
assets and liabilities denominated in foreign currencies are remeasured based on prevailing exchange rates and any resulting gains or losses are credited
or charged to income.

Translation of Foreign Currency Financial Statements

The reporting currency of the Company is the U.S. dollars. The functional currency of some of the Company’s subsidiaries is the local currency of

the respective entity. Accordingly, the financial statements of the foreign subsidiaries were translated into U.S. dollars at the following exchange rates:
assets and liabilities — current rate on the balance sheet date; shareholders’ equity — historical rates; income and expenses — average rate during the
period. The resulting translation adjustment is recorded as a separate component of comprehensive income.

Comprehensive Income (Loss)

Comprehensive income and loss represents net income (loss) plus the results of certain changes in shareholders’ equity during a period from
non-owner sources. The following table presents the components of accumulated other comprehensive income (loss) as of December 31, 2020, 2021 and

Legal Contingencies

The Company is regularly involved in various claims and legal proceedings. Periodically, the Company reviews the status of each significant
matter and assesses the potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can
be estimated, the Company

accrues a liability for the estimated loss. Because of uncertainties related to these matters, accruals are based only on the best information available at
the time. As additional information becomes available, the Company reassesses the potential liability related to the pending claims and litigation and
revises these estimates as appropriate. Such revisions in the estimates of the potential liabilities could have a material impact on the results of operations
and financial position.

Earnings Per Share

Basic earnings per share are computed by dividing net earnings attributable to ordinary shareholders by the weighted-average number of ordinary

shares outstanding during the period. Diluted earnings per share are computed by dividing net income attributable to ordinary shareholders by the
weighted-average number of ordinary shares and potentially dilutive shares of ordinary shares outstanding during the period. Dilutive shares outstanding
include unvested RSUs. Dilutive securities are excluded from the computation of the diluted income per share in periods when their effect is anti-
dilutive. The effect of dilutive securities of restricted stock units were 489 thousand shares (123 thousand ADSs), 563 thousand shares (141 thousand
ADSs) and 526 thousand shares (131 thousand ADSs) for the years ended December 31, 2020, 2021 and 2022, respectively.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718 Compensation — Stock Compensation. The value of our

restricted stock units is based on the fair value of our shares on the date of grant and expensed over the vesting period.

The fair value of RSUs is measured based on the grant date share price, less the present value of expected dividends during the vesting period,

discounted at a risk-free interest rate.

Treasury Stock

Treasury stock is stated at cost and shown as a reduction to shareholders’ equity.

The Company retires ordinary shares repurchased. Accordingly, upon retirement the excess of the purchase price over par value is allocated

between additional paid-in capital and retained earnings based on the average issuance price of the shares repurchased. A repurchase of ADSs is
recorded as treasury stock until the Company completes the withdrawal of the underlying ordinary shares from the ADS program.

Recent Accounting Pronouncements

In July 2021, the FASB issued an accounting update, which requires lessors to classify leases as operating leases if they have variable lease

payments that do not depend on an index or rate and would have selling losses at lease commencement if they were classified as sales-type or direct
financing leases. This amendment is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted. The adoption of this
amendment did not have a material impact on the Company’s results of operations, financial position, cash flows or financial statement disclosures.

In April 2006, the Company leased a property located in Taipei, Taiwan to a third party. The lessee has been renewing annually and last renewed

in March 2023. Net carrying value of the properties as of December 31, 2021 and 2022, was US$636 thousand and US$617 thousand, respectively.
Annual rental income from the lease is US$44 thousand.

In January 2022, the Company leased out a property located in Shanghai, China to a third party for three years starting on September 30, 2022.

Net carrying value of the property as of December 31, 2022, was US$3,284 thousand. Annual rental income from the lease is US$157 thousand.

In September 2018, the Company paid US$58,931 thousand to acquire land in Hsinchu, Taiwan for its future Taiwan headquarters building. In

January 2021, the Company broke ground at this site and began construction work.

8. GOODWILL

Goodwill is not amortized, but instead is reviewed and tested for impairment at least annually and whenever events or circumstances occur which
indicate that goodwill might be impaired. Goodwill that resulted from the Company’s acquisition of Shannon Systems in 2015 and Bigtera in 2017 were
US$33,204 thousand and US$625 thousand, respectively. Goodwill is tested for impairment annually on November 30. Total goodwill was nil as of
December 31, 2020 after recognizing an impairment charge for the Shannon reporting unit.

The Company applied a one-step quantitative test and recorded the amount of goodwill impairment as the excess of a reporting unit’s carrying

amount over its fair value. Fair value determinations are sensitive to changes in the underlying assumptions and factors including those relating to
estimating future operating cash flows to be generated from the reporting unit which are dependent upon historical data and internal forecasts and
projections developed by management. Assumptions used to determine fair value used are classified as Level 3 within the fair value hierarchy due to the
significant use of unobservable company-specific information. As a result of the goodwill impairment tests conducted as of November 30, 2020, the
Company determined that the carrying amounts for Shannon reporting unit exceeded the fair value and recorded goodwill impairment charges of
US$17,489 thousand in the fourth quarter of 2020. The Company used the discounted cash flow method to determine the fair value of the Shannon unit.

12. PENSION PLAN

SMI Taiwan, the Company’s largest operating company, is a Taiwan registered company and subject to Taiwan’s Labor Pension Act (the “New
Act”), which became effective on July 1, 2005, and the pension mechanism under the New Act is deemed a defined contribution plan. The employees
who were subject to the Labor Standards Law prior to July 1, 2005 (the “Old Act”) could choose to be subject to the pension mechanism under the New
Act or continue to be subject to the pension mechanism under the Old Act. For those employees who were subject to the Old Act and still work for the
Company after July 1, 2005 and have chosen to be subject to the Old Act, their seniority as of July 1, 2005 were maintained. The New Act prescribes
that the rate of contribution by an employer to employees’ pension accounts per month will not be less than 6% of each employee’s monthly salary.
According to the New Act, SMI Taiwan made monthly contributions and recognized pension costs of US$2,109 thousand, US$2,652 thousand and
US$3,317 thousand for the years ended December 31, 2020, 2021 and 2022, respectively.

The Company provides a defined benefit plan to the employees of SMI Taiwan under the Old Act that offers benefits based on an employee’s

length of service and average monthly salary for the six-month period prior to retirement. The Company contributes an amount equal to 2% of salaries
paid each month to a pension funds (the “Funds”), which is administered by the Labor Pension Fund Supervisory Committee established by the
government (the “Committee”) and deposited in the Committee’s name in the Bank of Taiwan. Before the end of each year, the Company assesses the
balance in the Funds. If the amount of the balance in the Funds is inadequate to pay retirement benefit for employees who conform to retirement
requirements in the next year, the Company is required to fund the difference in one appropriation that should be made before the end of March of the
next year. The government is responsible for the administration of all the defined benefit plans for the companies in Taiwan under the Old Act. The
government also sets investment policies and strategies, determines investment allocation and selects investment managers. As of December 31, 2021
and 2022, the asset allocation was primarily in cash, equity securities and debt securities. Furthermore, under the Old Act, the rate of return on assets
shall not be less than the average interest rate on a two-year time deposit published by the local banks. The government is responsible for any shortfall in
the event that the rate of return is less than the required rate of return. However, information on how investment allocation decisions are made, inputs
and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on
changes in plan assets for the period and significant concentrations of risk within plan assets is not fully available to the Company. Therefore, the
Company is unable to provide the required fair value disclosures related to pension plan assets. Future contributions will be based on 2% of the
employees’ annual salaries. As the benefits obligation has been fully funded, the Company contribution will be nil for the year ending December 31,
2023, which had been approved by the government on February 16, 2023.

For employees under defined contribution pension plans, pension costs are recorded based on the actual contributions made to employees’

individual pension accounts. For employees under defined benefit pension plans, pension costs are recorded based on actuarial calculations.
Determining the cost associated with such benefits is dependent on various actuarial assumptions, including discount rate, expected return on plan
assets, compensation increase, employee mortality and turnover rates. The Company reviewed its actuarial assumptions at the measurement date on
December 31 every year. The effect of modifications to assumptions is recorded in accumulated other comprehensive loss and amortized to net periodic
cost over future periods using the corridor method. The Company believes that assumptions utilized in recording its obligations under its plans are
reasonable based on its experience and market conditions. Independent actuaries perform the required calculations to determine expense in accordance
with U.S. GAAP. Actual results may differ from the actuarial assumptions and are generally accumulated and amortized into earnings over future
periods. The net periodic costs are recognized as employees render services necessary to earn the benefits.

The Company’s business operations are primarily located in China, Hong Kong, Macau, Taiwan and the US, where statutory and effective tax
rates in each jurisdiction are different, and our consolidated effective tax rate could change from period-to-period due to changing statutory tax rates,
availability of tax benefits and proportional income earned in each jurisdiction. The statutory tax rates in these jurisdictions range from 12 to

21%. For the year ended December 2020, the Company’s effective tax rate was 6.8%, lower than 19.1% and 18.8% in 2021 and 2022 due to changes in
proportional income earned by operations in key jurisdictions. Recent changes in tax policies will result in higher effective tax rates for the Company
beginning in 2021. Effective tax rates in each jurisdiction are generally lower than statutory rates due to tax credits for research and development and
other tax incentive programs and are determined by different government policies in each of the jurisdictions where the Company operates.

The Company consists of a Cayman parent holding company with U.S. and other non-Cayman operations. The applicable Cayman statutory rate is

zero for the Company for 2020, 2021, and 2022. A reconciliation of its income tax expense at the statutory rate and provision for income tax is shown

increased by US$991 thousand for the year ended December 31, 2021 and decreased by US$1,644 thousand for the year ended December 31, 2022. The
increase in valuation allowance in 2021 and decrease in valuation allowance in 2022 was primarily due to the uncertainty in generating sufficient taxable
income in the future and utilization of operating loss carryforwards before they expire.

As of December 31, 2022, the Company’s U.S. federal net operating loss carryforwards for federal income tax purposes were approximately

US$27,802 thousand as of December 31, 2022, expiring at various times starting from 2023 through 2037 for federal losses generated through
December 31, 2017, if not utilized. As a result of the U.S. Tax Cuts and Jobs Act (TCJA), all federal net operating losses of US$13,002 thousand that are
generated beginning January 1, 2018 and beyond will carryforward indefinitely.

As of December 31, 2022, the Company’s U.S. federal and state research and development tax credit carryforwards for federal and state income

tax purposes were approximately US$1,948 thousand and US$1,342 thousand, respectively. If not utilized, the federal tax credit carryforwards will
expire starting in 2042, while the state tax credit carryforward has no expiration date in California.

Current U.S. federal and California state laws include substantial restrictions on the utilization of net operating losses and credits in the event of an

“ownership change” of a corporation. Accordingly, the Company’s ability to utilize net operating loss and tax credit carryforwards may be limited as a
result of such “ownership change”. Such a limitation could result in the expiration of carryforwards before they are utilized.

As of December 31, 2022, the Company had accumulated undistributed earnings from a foreign subsidiary of US$487 million. No deferred tax

liability was recorded in respect of those amounts as these earnings are considered indefinitely reinvested. It is not practicable to estimate the amount of
unrecognized deferred tax liabilities for these undistributed foreign earnings.

Unrecognized Tax Benefit

A reconciliation of the beginning and ending balances of the total amounts of unrecognized tax benefits is as follows:

    19,001     26,317     37,105 

At December 31, 2022, the Company had US$37,105 thousand of unrecognized tax benefits that if recognized would affect the effective tax rate.
For the years ended December 31, 2020, 2021 and 2022, the total amount of interest expense and penalties related to uncertain tax positions recorded in
the provision for income tax expense was approximately US$430 thousand, US$1,040 thousand and US$1,037 thousand, respectively. The total amount
of accrued interest and penalties recognized as of December 31, 2021 and 2022 was US$6,368 thousand and US$6,777 thousand, respectively. The
Company does not expect uncertain tax positions to change in the next twelve months, except in the case of settlements with tax authorities, the
likelihood and timing of which are difficult to estimate.

15. EQUITY INCENTIVE PLAN

2015 Equity Incentive Plan

Restricted stock units are converted into shares of the Company’s ordinary shares upon vesting on one-for-one basis. The vesting of restricted
stock unit is subject to the employee’s continuing service to the Company. The cost of these awards is determined using the fair value of the Company’s
ordinary share on the date of the grant, and compensation is recognized on a straight-line basis over the requisite service period. The Company’s
restricted stock units are considered non-vested share awards as defined under ASC 718.

Office Building Construction

On February 18, 2021, the Company won a bid with a third-party to build an office building in Taipei and entered into a property development
agreement in May 2021, at which time it delivered a US$5,322 thousand performance bond secured by a certificate of deposit. Based on the terms of the
property development agreement, the Company is required to complete construction within three years after the construction license is approved.

Litigation

From time to time, the Company is subject to threats of litigation or actual litigation in the ordinary course of business, some of which may be

material. On April 5, 2022, Rampart Asset Management LLC, commenced a patent infringement lawsuit against the Company in the United States
District Court of the Eastern District of Texas, Marshall Divisions. On October 31, 2022, the parties settled and the Company paid Rampart US$390
thousand.

18. SEGMENT INFORMATION

The Company is the global leader and pioneer in developing NAND flash controllers for solid state storage devices. The Company currently
operates as one reportable segment. The chief operating decision maker (“CODM”) is the Chief Executive Officer. The fact that the Company operates
in only one reportable segment is because the decisions on allocation of resources and other operational decisions are made by the CODM based on his
direct involvement with the Company’s operations and product development.

The Company groups its products into two categories, based on the markets in which they may be used. The following summarizes the Company’s

revenue by product category:
