We use processes that require specialized raw materials that are generally available from a limited number of suppliers. We continue to attempt to qualify additional suppliers for our raw materials. The Securities and Exchange Commission (the “SEC”), as mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, has adopted new disclosure regulations for public companies that manufacture products containing certain minerals that are mined from the Democratic Republic of Congo and adjoining countries. These “conflict minerals” are commonly found in metals used in the manufacture of semiconductors. The implementation of these new requirements could adversely affect the sourcing, availability and pricing of metals used in the manufacture of our products. See “Item 1A. Risk Factors—Risks Related to Our Business—Compliance with new regulations regarding the use of “conflict minerals” could limit the supply and increase the cost of certain raw materials used in manufacturing our products.”

The following table sets forth certain information regarding our current executive officers:

From time to time, we may choose to sell assets, restructure business operations, shut down manufacturing lines or otherwise dispose of assets and businesses as part of management’s strategies to better align our product offerings with market demands and our customers’ needs. In connection with these activities, we face risks that we will disrupt service to our customers, lose business and incur significant costs related to such activities. These risks include potential damage to our reputation and customer relationships if we are unable to effectively transition such customer relationships to other production lines or products or if we cannot effectively manage our supplier and vendor relationships during such activities. In addition, we may also face claims or costs

Our industry is subject to constant and rapid technological change and product obsolescence as customers and competitors create new and innovative products and technologies. Products or technologies developed by other companies may render our products or technologies obsolete or noncompetitive, and we may not be able to access advanced process technologies, including smaller geometries, or to license or otherwise obtain essential intellectual property required by our customers.

We make significant decisions, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, personnel needs and other resource requirements, based on our estimates of customer demand and expected demand for and success of their products. The short-term nature of commitments by many of our customers and the possibility of rapid changes in demand for their products reduces our ability to estimate accurately future customer demand for our products. On occasion, customers may require rapid increases in supply, which can challenge our production resources and reduce margins. We may not have sufficient capacity at any given time to meet our customers’ increased demand for our products. Conversely, downturns in the semiconductor industry have caused and may in the future cause our customers to reduce significantly the amount of products they order from us. Because many of our costs and operating expenses are relatively fixed, a reduction in customer demand would decrease our results of operations, including our gross profit.

An important factor in our success is the extent to which we are able to utilize the available capacity in our fabrication facility. As many of our costs are fixed, a reduction in capacity utilization, as well as changes in other factors, such as reduced yield or unfavorable product mix, could reduce our profit margins and adversely affect our operating results. A number of factors and circumstances may reduce utilization rates, including periods of industry overcapacity, the inability to source sufficient materials necessary for manufacturing, low levels of customer orders, operating inefficiencies, strategic evaluations and decisions by our Board related our overall business, divisions and business lines, mechanical failures and disruption of operations due to expansion or relocation of operations, power interruptions and fire, flood or other natural disasters or calamities. The potential delays and costs resulting from these factors and circumstances could have a material adverse effect on our business, financial condition and results of operations.

Historically, we have relied on a limited number of customers for a substantial portion of our total revenue. If we were to lose key customers or if customers cease to place orders for our high-volume products, particularly our display products, our financial results could be adversely affected. In addition, our arrangements with and reliance on key customers may make it less practicable to pursue certain opportunities with other potential new and existing customers. For the years ended December 31, 2020, 20192022, 2021 and 2018,2020, our ten largest customers accounted for 87.6%69.4%, 89.5%79.8% and 84.9%87.6% of net sales from our standard products business, respectively. For the year ended December 31, 2022, sales to Samsung Display represented 19.0% of net sales from our standard products business and 80.2% of net sales from our Display Solutions business line, and SAMT represented 13.8% of net sales from our standard products business and 18.1% of net sales from our Power Solutions business line. For the year ended December 31, 2021, sales to Samsung Display represented 42.5% of net sales from our standard products business and 89.7% of net sales from our Display Solutions business line, and SAMT represented 10.4% of net sales from our standard products business and 19.8% of net sales from our Power Solutions business line. For the year ended December 31, 2020, sales to Samsung Display represented 56.2% of net sales from our standard products business and 87.5% of our Display Solutions division’s net sales. For the year ended December 31, 2019, sales to Samsung Display represented 53.8% of net sales from our standard products business and 84.5% of our Display Solutions division’s net sales. For the year ended December 31, 2018, sales to Samsung Display represented 34.1% of net sales from our standard products business and 56.6% of our Display Solutions division’s net sales, and LG Display represented 23.4% of net sales from our standard products business and 38.9% of our Display Solutions division’s net sales.line. Significant reductions in sales to any of these customers, especially our few largest customers, the loss of other major customers or a general curtailment in orders for our high-volume products within a short period of time could adversely affect our business.

The semiconductor products we develop and sell are subject to rapid declines in average selling prices. From time to time, we have had to reduce our prices significantly to meet customer requirements, and we may be required to reduce our prices in the future. This would cause our gross profit to decrease. Our financial results will suffer if we are unable to offset any reductions in our average selling prices by increasing our sales volumes, reducing our costs or developing new or enhanced products on a timely basis with higher selling prices or gross profit.

The semiconductor industry is highly competitive and includes hundreds of companies, a number of which have achieved substantial market share within both our product categories and end markets. Current and prospective customers for our products and services evaluate our capabilities against the merits of our

Demand for our products will depend in part on the demand for various consumer electronics products, in particular, mobile phones and multimedia devices, digital televisions, flat panel displays, mobile PCs and digital cameras, which in turn depends on general economic conditions and other factors beyond our control. If our customers fail to introduce new products that employ our products or component parts, demand for our products will suffer. To the extent that we cannot offset periods of reduced demand that may occur in these markets through greater penetration of these markets or reduction in our production and costs, our sales and gross profit may decline, which would negatively impact our business, financial condition and results of operations.

We expend considerable resources on winning competitive selection processes, known as design-wins, to develop semiconductor products for use in our customers’ products. These selection processes are typically lengthy and can require us to incur significant design and development expenditures. We may not win the competitive selection process and may never generate any revenue despite incurring significant design and development expenditures. Once a customer designs a semiconductor into a product, that customer is likely to continue to use the same semiconductor or enhanced versions of that semiconductor from the same supplier across a number of similar and successor products for a lengthy period of time due to the significant costs associated with qualifying a new supplier and potentially redesigning the product to incorporate a different semiconductor. If we fail to achieve initial design-wins in a customer’s qualification process, we may lose the opportunity for significant sales to that customer for a number of products and for a lengthy period of time. This may cause us to be unable to recoup our investments in our semiconductor products, which would harm our business.

23

We invest significant resources in our research and development. Our research and development efforts, however, may not yield profitable or commercially viable products. During each stage of research and development, there is a substantial risk that we will have to abandon a potential product that is no longer marketable and in which we have invested significant resources. In the event we are able to develop viable new products, a significant amount of time will have elapsed between our investment in the necessary research and development effort and the receipt of any related revenues.

Our growth strategy is to leverage our advanced analog and mixed-signal technology platform, continue to innovate and deliver new products, increase business with existing customers, broaden our customer base, aggressively grow our power business, and drive execution excellence. If we are unable to execute our growth strategy effectively, we may not be able to take advantage of market opportunities, execute our business plan or respond to competitive pressures. Moreover, if our allocation of resources does not correspond with future demand for particular products, we could miss market opportunities and our business and financial results could be materially and adversely affected.

Our key executives have substantial experience and have made significant contributions to our business, and our continued success is dependent upon the retention of our key management executives. The loss of such key personnel would have a material adverse effect on our business. In addition, our future success depends on our ability to attract and retain skilled technical and managerial personnel. We do not know whether we will be able to retain all of these employees as we continue to pursue our business strategy. The loss of the services of key employees, especially our key design and technical personnel, or our inability to retain, attract and motivate qualified design and technical personnel, could have a material adverse effect on our business, financial condition and results of operations. This could hinder our research and product development programs or otherwise have a material adverse effect on our business.

As of December 31, 2020, 3952022, 485 employees, or approximately 45%56% of our employees, were represented by the Magnachip Semiconductor Labor Union.Unions. We can offer no assurance that any issues with the labor union and other employees will be resolved favorably for us in the future, that we will not experience work stoppages or other labor problems in future years or that we will not incur significant expenses related to such issues.

As part of our business strategy, we may seek to enter into business combinations, investments, joint ventures and other strategic alliances with other companies in order to maintain and grow revenue and market presence as well as to provide us with access to technology, products and services. Any such transaction would be accompanied by risks that may harm our business, such as difficulties in assimilating the operations, personnel and products of an acquired business or in realizing the projected benefits, disruption of our ongoing business,

The manufacturing of semiconductors involves highly complex processes that require precision, a highly regulated and sterile environment and specialized equipment. Defects or other difficulties in the manufacturing process can prevent us from achieving acceptable yields in the manufacturing of our products, which could lead to higher costs, a loss of customers or delay in market acceptance of our products. Slight impurities or defects in the photomasks used to print circuits on a wafer or other factors can cause significant difficulties, particularly in connection with the production of a new product, the adoption of a new manufacturing process or any expansion of our manufacturing capacity and related transitions. We may also experience manufacturing problems in achieving acceptable yields as a result of, among other things, transferring production to other facilities, upgrading or expanding existing facilities or changing our process technologies. Yields below our target levels can negatively impact our gross profit and may cause us to eliminate underperforming products.

We use independent foundry services for certain of our OLED Display Solutions products and Power Solutions products. Silicon wafer production at these facilities is allocated solely by our vendors and beyond our direct control. Therefore, any disruption in wafer supply formfrom these vendors could have a material impact on our revenue and results of operations.

Increases in demand for semiconductor products have resulted in a global shortage of manufacturing capacities.capacity over the prior two years. As a result, we may experience increases in the costs to manufacture our products and may not be able to manufacture and deliver all of the orders placed by our customers. We are not able to foresee when the current shortage of manufacturing capacity will subside. If we are unable secure manufacturing capacities from our current subcontractors, our ability to deliver our products to our customers may be negatively impacted. Also, our subcontractors may increase their fees, which would result in an increase in our

We procure materials and electronic and mechanical components from international sources and original equipment manufacturers. We use a wide range of parts and materials in the production of our semiconductors, including silicon, processing chemicals, processing gases, precious metals and electronic and mechanical components, some of which, such as silicon wafers, are specialized raw materials that are generally only available from a limited number of suppliers. If demand increases or supply decreases for any reason, the costs of our raw materials could significantly increase. For example, worldwide supplies of silicon wafers, an important raw material for the semiconductors we manufacture, werehave been constrained in recent years due to an increased demand for silicon. We from time to time may enter into multi-year agreements, which specify future quantities and pricing of materials to be supplied by the vendors of these materials; however, this option may not be available to us and we cannot assure that supply increases will match demand increases. If we cannot obtain adequate materials in a timely manner or on favorable terms for the manufacture of our products, revenues and results of operations will decline.

The SEC, as mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, adopted disclosure regulations for public companies that manufacture products containing certain minerals that are mined from the Democratic Republic of Congo and adjoining countries and procedures pertaining to a manufacturer’s efforts regarding the source of such minerals. These “conflict minerals” are commonly found in metals used in the manufacture of semiconductors. Manufacturers are also required to disclose their efforts to prevent the sourcing of such minerals and metals produced from them. The implementation of these requirements could adversely affect the sourcing, availability and pricing of metals used in the manufacture of our products. We may also incur additional costs to comply with the disclosure requirements, including costs related to determining the source of any of the relevant minerals used in our products. We may also face difficulties in satisfying customers who may require that our products be certified as free of “conflict materials,” which could harm our relationships with these customers and lead to a loss of revenue.

Our semiconductors are incorporated into a number of end products, and our business is exposed to product return, warranty and product liability risk and the risk of negative publicity if our products fail. Although we maintain insurance for product liability claims, the amount and scope of our insurance may not be adequate to cover a product liability claim that is asserted against us. In addition, product liability insurance could become more expensive and difficult to maintain and, in the future, may not be available on commercially reasonable terms, or at all.

Our company’s organizational structure was created in part based on certain interpretations and conclusions regarding various tax laws, including withholding tax and other tax laws of applicable jurisdictions. Our interpretations and conclusions regarding tax laws, however, are not binding on any taxing authority and, if these interpretations and conclusions are incorrect, if our business were to be operated in a way that rendered us ineligible for tax exemptions or caused us to become subject to incremental tax, or if the authorities were to change, modify or have a different interpretation of the relevant tax laws, we could suffer adverse tax and other financial consequences, and the anticipated benefits of our organizational structure could be materially impaired. Our company’s organizational structure and other tax positions are subject to review by tax authorities in the local and other jurisdictions where we operate our business.

On August 17, 2020, the U.S. Department of Commerce expanded the scope of export restrictions as applied to products directed to Huawei and its affiliates listed on the Bureau of Industry and Security’s Entity List (collectively,

We attempt to protect our intellectual property rights, both in the USU.S. and in foreign countries, through a combination of patent, trademark, copyright, mask works and trade secret laws, as well as licensing agreements and third-party nondisclosure and assignment agreements. Because of the differences in foreign trademark, patent and other laws concerning proprietary rights, our intellectual property rights may not receive the same degree of protection in foreign countries as they would in the US.U.S. In particular, the validity, enforceability and scope of protection of intellectual property in China, where we derive a significant portion of our net sales, and certain other countries where we derive net sales, are uncertain and still evolving and historically have not protected, and may not protect in the future, intellectual property rights to the same extent as do the laws and enforcement procedures in the US.U.S. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason could have a material adverse effect on our business, results of operations and financial condition.

We are subject to a variety of environmental, health and safety laws and regulations in each of the jurisdictions in which we operate, governing, among other things, air emissions, wastewater discharges, the generation, use, handling, storage and disposal of, and exposure to, hazardous substances (including asbestos) and wastes, soil and groundwater contamination and employee health and safety. These laws and regulations are complex, change frequently and have tended to become more stringent over time. Among them is the Act on Remediation and Compensation for Damages arising from Environmental Contamination which came into effect in Korea on January 1, 2016 and provides for strict liability of business entities in violation of the act and alleviates the burden of proof for the damaged party. Further, under the amendment to the Act on the Control and Aggravated Punishment of Environmental Offenses that becomes effective on November 27, 2020, certain environmental offenses such as illegally emitting specified hazardous air pollutants or emitting air pollutants without necessary permits will be subject to penalties of up to 5% of the sales amount generated from the relevant business. Moreover, to effectively respond to environmental crimes, on November 14, 2022, a joint investigation team was established, consisting of experts from both national and local governments, including the prosecutor’s office, the Ministry of Environment. As a result, we have increased potential exposure to liability for environmental contaminations that might have existed in the past or would arise in the future. There can be no assurance that we have been, or will be, in compliance with all such laws and regulations or that we will not incur material costs or liabilities in connection with these laws and regulations in the future. The adoption of new environmental, health and safety laws, the failure to comply with new or existing laws, or issues relating to hazardous substances could subject us to material liability (including substantial fines or penalties), impose the need for additional capital equipment or other process requirements upon us, curtail our operations or restrict our ability to expand operations.

Enacted on January 26, 2021 the SAPA was enactedand effective as of January 27, 2022 in Korea, whichthe SAPA will impose enhanced liability exposure for workplace accidents. The legislative goal of the SAPA is to prevent serious accidents by prescribing punishments and punitive damages liability for business owners or responsible management personnel who have violated safety and health measures in the event of such serious accidents (serious industrial accidents and serious civil accidents). Since the law applies to businesses in Korea with 50 or more full-time employees starting from January 27, 2022, our Korean subsidiary is expected to bebecomes subject to the law after the effective date. According to the SAPA, if a serious occupational accident occurs that results in at least one deceased person, at least two persons wounded for six months or more, or at least three persons suffering from occupational diseases within a one year period, if the “business owners or responsible management personnel” of the relevant business place is found to have failed to perform its “obligation to secure safety and health,” that person may be subject to imprisonment for up to 7 year or a fine of up to KRW 100 million (in case of death, imprisonment for not less than 1 year or a fine of not less than KRW 1 billion). Additionally, if there was negligence of the company in giving due attention and supervision to prevent such accident, the company will be

In the ordinary course of our business, we collect and store sensitive data, including IP and other proprietary information about our business and that of our customers, suppliers and business partners. Secure maintenance, processing and transmission of this information is critical to our operations and business strategy. We may be subject to disruptions, breaches or cyber-attacks of our secured networks and information technology systems caused by illegal hacking, criminal fraud or impersonation, computer viruses, acts of vandalism or terrorism or employee error, and our security measures or those of any third party service providers we use may not detect or prevent such security breaches. We may incur significant costs to eliminate or alleviate cybersecurity breaches and vulnerabilities, which could be significant, and our efforts to protect against such breaches or vulnerabilities may not be successful and could result in system interruptions that may materially impede our sales, manufacturing, distribution, finance or other critical functions. Any such compromise of our information security could also result in the unauthorized publication of our confidential business or proprietary information or that of other parties with which we do business, an interruption in our operations, the unauthorized transfer of cash or

Most of our subsidiaries are organized or incorporated outside of the USU.S. and some of our directors and executive officers as well as our independent auditors are organized or reside outside of the US.U.S. Most of our and our subsidiaries’ assets are located outside of the USU.S. and in particular, in Korea. Accordingly, any judgment obtained in the USU.S. against us or our subsidiaries may not be collectible in the US.U.S. As a result, it may not be possible for you to effect service of process within the USU.S. upon these persons or to enforce against them or us court judgments obtained in the USU.S. that are predicated upon the civil liability provisions of the federal securities laws of the USU.S. or of the securities laws of any state of the US.U.S. In particular, there is doubt as to the enforceability in Korea or any other jurisdictions outside the US,U.S., either in original actions or in actions for enforcement of judgments of USU.S. courts, of civil liabilities predicated on the federal securities laws of the USU.S. or the securities laws of any state of the US.

We are a holding company with no independent operations of our own. Our subsidiaries conduct substantially all of the operations necessary to fund our obligations. Our ability to pay dividends or to make

During industry downturns and for other reasons, we may need to record impairment, restructuring or other restructuring related charges. In the future, we may need to record additional impairment charges or to further restructure our business or incur additional restructuring charges, any of which could have a material adverse effect on our results of operations or financial condition.

All industries, including the semiconductor industry, are subject to legal claims, with and without merit, that may be particularly costly and which may divert the attention of our management and our resources in general.

The trading price of our common stock might be subject to wide fluctuations. Factors, some of which are beyond our control, that could affect the trading price of our common stock may include:

The concentration of ownership of our common stock by certain stockholders may limit the ability of other stockholders to influence corporate matters and, as a result, we may take actions that our public stockholders do not view as beneficial. For example, ourany concentration of ownership could have the effect of delaying or preventing a change in control or otherwise discouraging a potential acquirer from attempting to obtain control of us, which in turn could cause the market price of our common stock to decline or prevent our stockholders from realizing a premium over the market price for their shares of our common stock.

Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. Among other things, our certificate of incorporation and bylaws:

We are involved in a variety of legal matters, most of which we consider routine matters that arise in the normal course of business. These routine matters typically fall into broad categories such as those involving customers, employment and labor and intellectual property. Intellectual property litigation and infringement claims, in particular, could cause us to incur significant expenses or prevent us from selling our products. We are currently not involved in any legal proceedings that we believe would have a material adverse effect on our business, financial condition or results of operations.
