MagnaChip (MX) Risk Analysis

Our Gumi fabrication facilityrequires a stable supply of electricity to support continuous manufacturing operations and sensitive production equipment. As we seek to maintain and improve our production capabilities, we may be required to further modernize our facilities and equipment and upgrade our manufacturing facilities. In addition, we rely on third parties to supply stable power supply and other power systems infrastructure to support our fabrication operations, and such third parties may from time to time perform maintenance, upgrades or other work relating to the supporting power systems infrastructure, including a planned upgrade to certain power infrastructure serving our Gumi fabrication facility that is currently expected to result in a temporary power interruption and related operational adjustments. Any damage to fabrication equipment, disruption during the resumption of operations, production delays, wafer losses, deterioration in yield or other operational inefficiencies resulting from such upgrade could materially and adversely affect our business, financial conditions and results of operations.

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.

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.

Increases in demand for semiconductor products have in the past and may again in the future result in a global shortage of manufacturing capacity. 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. If we are unable to 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 manufacturing costs, which we may not be fully able to pass to our customers. These factors could cause a negative impact on our 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, 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, 2025 and 2024, our ten largest customers accounted for 74.3% and 73.4% of net sales from our Power Solutions business, respectively. For the year ended December 31, 2025, sales to SAMT represented 29.7% of net sales from our Power Solutions business. For the year ended December 31, 2024, sales to SAMT represented 25.4% of net sales from our Power Solutions business. Significant reductions in sales to our largest customer, the loss of any 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.

We generally do not obtain firm, long-term purchase commitments from our customers. Customers may cancel their orders, reduce quantities or delay production for a number of reasons. Cancellations, reductions or delays by a significant customer or by a group of customers, which we have experienced as a result of periodic downturns in the semiconductor industry, or failure to achieve design-wins, have affected and may continue to affect our results of operations adversely. These risks are exacerbated because many of our products are customized, which hampers our ability to sell excess inventory to the general market. We may incur charges resulting from the write-off of obsolete inventory. In addition, while we do not obtain long-term purchase commitments, we generally agree to the pricing of a particular product over a set period of time. If we underestimate our costs when determining pricing, our margins and results of operations would be adversely affected.

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, have 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.

Since 2015, our Korean subsidiary has been subject to K-ETS, a new set of greenhouse gas emissions regulations, under the Act on Allocation and Trading of Greenhouse Gas Emission Allowances. Under K-ETS, our Korean subsidiary was allocated a certain amount of emissions allowance in accordance with the National Allocation Plan prepared by the Korean government, and are required to meet their allocated target by either reducing emissions or purchasing allowances from other participants or the government in the emission trading market. Reduction of our emissions or energy consumption may result in additional and potentially costly compliance or remediation expenses, including potentially the installation of equipment and changes in the type of materials we use in manufacturing, as well as cost of procuring emission allowances to cover the excess emissions, which could adversely affect our financial position and results of operations. During the first implementation period from 2015 to 2017 and second implementation period from 2018 to 2020, we did not exceed the allocated emission amount. Our Korean subsidiary has been allocated emissions allowance in the third implementation period from 2021 to 2025, and we do not expect to exceed the allocated emission amount during the third implementation period. If, however, our Korean subsidiary exceeds the allocated emission amount the third implementation period, we will be required to pay for the excess emissions and may be subject to other regulatory action. We will continue to monitor our compliance with the emissions allowance on a yearly basis. In addition, from time to time, if we assess that we have excess allowances, we may sell such excess allowances to manufacturers in the emission market in Korea. Furthermore, the Korean legislature enacted the Framework Act on Carbon Neutrality and Green Growth for Responding to Climate Change (the "Carbon Neutrality Framework Act") on September 24, 2021. The Carbon Neutrality Framework Act aims to reduce greenhouse gas emissions by more than 35% by 2030 (compared to 2018) and proclaims the achievement of carbon neutrality by 2050 as a national vision. The Carbon Neutrality Framework Act is significant in that it legislates carbon neutrality and greenhouse gas reduction objectives, and enables the central administrative agencies, local governments and public institutions to implement various measures towards such objectives. On March 25, 2022, the Enforcement Decree of the Carbon Neutrality Framework Act (the "Enforcement Decree") was enacted. The Enforcement Decree aims to provide details required for the execution of items prescribed under the Carbon Neutrality Framework Act. The key provisions of the Enforcement Decree include those setting the mid-to long-term greenhouse gas reduction goal at 40% and implementing the climate change impact assessment scheme. Based on that, on April 11, 2023, the Korean government published the 1st National Basic Plan for Carbon Neutrality and Green Growth (the "Basic Plan"). The Basic Plan is a national plan for responding to the climate crisis and sustainable development. Including annual reduction goals and implementation measures for each sector (e.g., industry and transportation), the Basic Plan will be updated every five years over the next 20 years between 2023 and 2042. It is anticipated that the Carbon Neutrality Framework Act and the Basic Plan, which aims to promote the harmonious development of the economy and the environment in conjunction with active greenhouse gas reduction measures, will serve as the foundation for the government's climate change response policy going forward. Meanwhile, on August 29, 2024, the Constitutional Court of Korea (the "Constitutional Court") held that Article 8, Paragraph 1 of the Carbon Neutrality Framework Act is unconstitutional. This provision mandates the government to establish a national mid- to long-term target for reducing greenhouse gas emissions by at least 35% from 2018 levels by 2030 which is prescribed by presidential decree. The Constitutional Court ruled that this provision is indeed in violation of the Constitution because it fails to specify any emissions reduction targets beyond 2031, thereby infringing upon the petitioners' right to clean environment. Considering that the extensive legislative authority to determine reduction targets during the period from 2031 to 2049, the Constitutional Court held that the provision would remain in effect until a legislative amendment is enacted, with a deadline set for February 28, 2026. Reflecting the ruling of the Constitutional Court, the government determined in November 2025 to set the 2035 Nationally Determined Contribution (NDC) at a reduction target of 53% to 61% compared to 2018 net emissions levels.

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.

Under the Act on Prevention of Leakage and Protection of Industrial Technology of Korea (the "ITA"), any export (including various means of outflow, such as sale or transfer outside Korea) of National Core Technology ("NCT") by the Korean Ministry of Trade, Industry and Resources (the "MOTIR") requires the filing of a prior-report with, and the acceptance of the same by, the MOTIR. Under the Act on Special Measures for Strengthening and Protecting the Competitiveness of the National High-Tech Strategic Industry (the "Special Act"), any export of National High-Tech Strategic Technology ("NHST") requires prior approval from the MOTIR. Any such export of NCT or NHST without the acceptance of the prior-report with the MOTIR or the prior approval from the MOTIR may be subject to corrective orders by the MOTIR and may also be subject to criminal sanctions. The Notification Regarding Designation of National Core Technologies issued by the MOTIR was amended on July 14, 2021 to add certain technologies to the list of NCT designated by the MOTIR, and the amended list includes the OLED DDI design technology for driving display panels. The MOTIR designated certain technologies, including the OLED DDI design technology for driving display panels, as NHST under the Special Act. In the event that our Korean subsidiary, Magnachip Semiconductor, Ltd. ("MSK"), license or sell certain intellectual properties relating to OLED Display Driver IC ("OLED DDI") to overseas entities, such license or sale may constitute an export of NCT and NHST and may be subject to both NCT and NHST restrictions, and therefore the MOTIR's acceptance of prior reports and prior approval. There is no assurance that any prior-reports for the export will be accepted by the MOTIR or we will obtain any prior approval for the export from the MOTIR when such license or sale is pursued in the future. In addition, in the event that there is any M&A transaction with respect to MSK that results in non-Korean ownership of 50% or more, or exertion of control over the appointment of officers/management by a non-Korean person or entity as the largest shareholder, a prior-report with and the acceptance by the MOTIR is required under the ITA and a prior approval from the MOTIR is required under the Special Act. There is no assurance that any report for an M&A transaction involving non-Korean acquirers or investors will be accepted by the MOTIR, nor we can assure approval for the M&A transaction from the MOTIR when such transaction is pursued in the future.
