manufacturing base serves both our display driver and power management businesses and Semiconductor Manufacturing Services customers, allowing us to optimize our asset utilization and leverage our investments across our product and service offerings. Analog and mixed-signal manufacturing facilities and processes are typically distinguished by design and process implementation expertise rather than the use of the most advanced equipment. These processes also tend to migrate more slowly to smaller geometries due to technological barriers and increased costs. For example, some of our products use high-voltage technology that requires larger geometries and that may not migrate to smaller geometries for several years, if at all. As a result, our manufacturing base and strategy do not require substantial investment in leading edge process equipment, allowing us to utilize our facilities and equipment over an extended period of time with moderate required capital investments.

On December 4, 2014, our Board of Directors approved a plan to close the Company’s six-inch fabrication facility in Cheongju, Korea (the “6-inch fab”). This plan is expected to be substantially implemented and the 6-inch fab is expected to be closed by the end of fiscal year 2015. The Company currently plans to transfer certain 6-inch fab employees to the Company’s other facilities.

We compete based on design experience, manufacturing capabilities, the ability to service customer needs from the design phase through the shipping of a completed product, length of design cycle and quality of technical support and sales personnel. Our ability to compete successfully will depend on internal and external variables, both within and outside of our control. These variables include the timeliness with which we can develop new products and technologies, product performance and quality, manufacturing yields, capacity availability, customer service, pricing, industry trends and general economic trends.

Employees

Our worldwide workforce consisted of 3,399 employees (full- and part-time) as of December 31, 2014, of which 415 were involved in sales, marketing, general and administrative, 471 in research and development (including 252 with advanced degrees), 115 in quality, reliability and assurance and 2,398 in manufacturing (comprised of 372 in engineering and 2,026 in operations). As of December 31, 2014, our workforce consisted of 3,399 employees, of which 2,144 employees, or approximately 63% of our workforce, were represented by the MagnaChip Semiconductor Labor Union.

Environmental

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 waste, 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. For example, the Korean government’s Enforcement Decree to the Framework Act on Low Carbon Green Growth became effective in April 2010. Certain designated businesses, including our Korean subsidiary, were required to submit plans to reduce greenhouse emissions and energy consumption. Our Korean subsidiary set emissions and consumption targets and in 2011 negotiated an implementation plan with Korean governmental authorities. Each year thereafter, our Korean subsidiary was required to agree on emissions and consumption targets with Korean governmental authorities and submit an independently verified report of prior year’s compliance. Beginning in 2015, our Korean subsidiary became subject to a new set of greenhouse gas emissions regulation, the Korean Emissions Trading Scheme, or K-ETS, 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 is required to meet its allocated target by either reducing the emission or purchasing the allowances from other participants in the emission trading market. Another example is the newly reinforced regulations on chemicals under Chemicals Control Act and K-REACH, which came into effect on January 1, 2015. Under these laws, our Korean subsidiary is required to comply with various requirements to report, evaluate, manage and ensure the safe usage of the chemicals used in its facilities. There can be no assurance that we have been or will be in compliance with all of these 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 and 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.

Raw Materials

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, 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.”

Item 1A. Risk Factors

You should carefully consider the risk factors set forth below as well as the other information contained in this Report. Any of the following risks could materially and adversely affect our business, financial condition or results of operations. As a result, the price of our common stock could decline and you could lose all or part of your investment in our common stock. Additional risks and uncertainties not currently known to us or those currently viewed by us to be immaterial may also materially and adversely affect our business, financial condition or results of operations.

Risks Related to Our Restatement of Prior Period Financial Data, Failure to File Timely Periodic Reports with the SEC and Our Internal Control Over Financial Reporting

We face risks related to our restatement of prior period financial data and being delayed in our SEC reporting obligations if we are unable to resume a timely filing schedule.

As discussed in our Annual Report on Form 10-K for the year ended December 31, 2013 (the “2013 Form 10-K”) in Note 2 to our consolidated financial statements under “Item 8. Financial Statements and Supplementary Data” in our 2013 Form 10-K, our Audit Committee concluded that certain of our previously issued financial statements should no longer be relied upon because of certain errors in those financial statements. The 2013 Form 10-K restated and corrected the following financial statements of the Company (the “Restatement”): (i) the audited consolidated balance sheets as of December 31, 2012 and 2011 and consolidated statements of operations, comprehensive income, changes in stockholders’ equity and cash flows for each of the years ended December 31, 2012 and 2011; and (ii) the five year selected financial data presented in 2013 Form 10-K.

As a result of the Restatement, our SEC reporting obligations have been delayed. We filed our 2013 Form 10-K and 2014 Form 10-Qs on February 12, 2015, and the filing of this Report is not timely. While we expect to resume a timely filing schedule with respect to our Form 10-Q for the second quarter of 2015, we can provide no assurances as to when we will resume a timely filing schedule with respect to our future SEC reports. Even if we resume a timely filing schedule, we expect to continue to face many of the risks and challenges related to the Restatement, including the following:

We cannot assure that all of the risks and challenges described above will be eliminated and that lost business opportunities can be recaptured or that general reputational harm will not persist. If one or more of the foregoing risks or challenges persist, our business, operations and financial condition are likely to be materially and adversely affected.

We concluded that there were material weaknesses in our internal control over financial reporting as of December 31, 2014, which adversely affected our ability to timely and accurately report our results of operations and financial condition. These material weaknesses have not been fully remediated as of the filing date of this Report and we cannot assure that other material weaknesses will not be identified in the future. If we fail to maintain an effective system of internal control over financial reporting, the accuracy and timing of our financial reporting may be adversely affected.

As reported in “Item 9A. Controls and Procedures” of this Report, we have concluded that there are material weaknesses in our internal control over financial reporting and that our disclosure controls and procedures were ineffective as of December 31, 2014. It is necessary for us to maintain effective internal control over financial reporting to prevent fraud and errors and to maintain effective disclosure controls and procedures so that we can provide timely and reliable financial and other information. A failure to maintain adequate internal controls may adversely affect our ability to provide financial statements that accurately reflect our financial condition and report information on a timely basis. This could cause investors to lose confidence in our reported financial and other information, cause our securities to trade at a decreased price and cause an adverse effect on our business and results of operations. A failure to remediate material weaknesses in our internal control over financial reporting could result in further restatements of financial statements and correction of other information filed with the SEC or otherwise made publicly available.

The processes undertaken to effect the Restatement may not have been adequate to identify and correct all errors in our historical financial statements and, as a result, we may discover additional errors and our financial statements remain subject to the risk of future restatement.

The completion of our Restatement involved many months of review and analysis, including highly technical analyses of our contracts and business practices, estimates and assumptions made by management, tax accounting and the proper application of relevant accounting rules and pronouncements. Many of the enhancements and changes to our processes are ongoing as of the filing date of this Report, and we continue to integrate the complex changes we have already made. Given the complexity and scope of these exercises, and notwithstanding the extensive time, effort and expense that went into them, we cannot assure that these processes were adequate to identify and correct all errors in our historical financial statements or that additional accounting errors will not come to light in the future in these or other areas.

While we have performed additional analyses and other procedures, and either implemented or plan to implement and test remediation measures as of the filing date of this Report, the previously identified material weaknesses have not been fully addressed and remediated. We continue to improve our internal control over financial reporting and disclosure controls and procedures by, among other things:

As a result, we cannot assure that we will not discover additional errors, that future financial reports will not contain misstatements or omissions, that future restatements will not be required, or that we will be able to timely comply with our reporting obligations in the future.

We may also be required to amend this Report and/or file other amended reports related to the Restatement. This would require us to devote substantial internal and external resources and cause us to incur significant fees and expenses for additional audit services as well as accounting and other consulting services. These fees and expenses, as well as the substantial time devoted by our management to make such filings with the SEC, could have a material adverse effect on our business, profitability and financial condition.

The Restatement has caused delays in filing this Report, which may result in future delays in our SEC reporting.

Our ability to resume a timely filing schedule with respect to our SEC reports is subject to a number of contingencies, including whether we continue to identify errors in our consolidated financial statements and effective remediation of the identified material weaknesses in our internal control over financial reporting, including processes and training related thereto.

If we become delayed again in our SEC reporting obligations, investors would need to evaluate certain decisions with respect to our securities in light of a lack of current financial information. Accordingly, if in the future we are not current in our SEC reporting obligations, any investment in our securities would involve a greater degree of risk. Any such lack of current public information may have an adverse impact on investor confidence, which could lead to a reduction in our stock price and market capitalization and an increase in our cost of capital. In addition, if we become delayed again in our SEC reporting obligations, we will be precluded from registering our securities with the SEC for offer and sale. This may preclude us from raising debt or equity financing in the public markets and limit our access to the private markets and could also limit our ability to use stock options and other equity-based awards to attract, retain and provide incentives to our employees.

If we fail to timely file our future SEC reports, we may incur additional interest charges under the indenture governing our senior notes and/or our bondholders may seek to accelerate the principal amount of our senior notes, which would likely have a material adverse effect on our business, results of operations and financial condition.

The reporting covenant contained in the indenture relating to our outstanding 6.625% senior notes due 2021 (the “2021 Notes”) requires us to file certain quarterly, annual and current reports with the SEC within the time periods specified in the SEC’s rules and regulations applicable to such reports (subject in some cases to applicable extension periods). Additionally, under the Indenture, the trustee or the holders of 25% or more of the outstanding principal amount of the 2021 Notes have the right to notify us if they believe we have breached a covenant under the Indenture and may, following any applicable cure periods, declare an event of default under the Indenture and cause the outstanding principal amount of the 2021 Notes to become immediately due and payable.

Because of the delay in filing our 2013 Form 10-K and certain of our other SEC reports, the trustee under the indenture relating to the 2021 Notes sent notices of default under the indenture initiating the 60-day cure periods thereunder. Pursuant to the terms of the indenture, we elected, for a period of up to 180 days after the initial event of default related to a breach of the reporting covenant, to pay additional interest on the 2021 Notes of 0.25% per annum. We also received a notice of default from the trustee as a result of our failure to timely file this Report. If we fail to timely file our future SEC reports, we could again be subject to conditional interest charges in the future. If any such future reporting failure continued past the 60-day cure period and the 180-day additional interest period, the 2021 Notes could be subject to acceleration by the trustee or the holders of 25% or more of the outstanding principal amount thereof. Any such acceleration would likely have a material adverse effect on our business, results of operations, and financial condition.

The delay in filing this Report with the SEC and any failure to satisfy other NYSE listing requirements could cause the NYSE to commence suspension or delisting procedures with respect to our common stock.

The Company was notified by the NYSE that, as a result of its failure to timely file this Report for the fiscal year ended December 31, 2014 with the SEC, it was subject to the procedures specified in Section 802.01E (SEC Annual Report Timely Filing Criteria) of the Listed Company Manual of the NYSE. We believe that the filing of this Report satisfied the NYSE’s requirement to file an Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

Any other failure to satisfy NYSE listing requirements, including delays in the failure to file the 2015 Q1 10-Q or timely file future SEC reports, if not waived by the NYSE, could cause the NYSE to commence suspension or delisting procedures with respect to our common stock. The commencement of any suspension or delisting procedures and any actual suspension or delisting of our common stock by the NYSE remains, at all times, at the discretion of the NYSE and would be publicly announced by the NYSE. The delisting of our common stock from the NYSE may have a material adverse effect on us by, among other things, causing investors to dispose of our shares and limiting:

The outcome of litigation and other claims as well as regulatory examinations, investigations, proceedings and orders arising out of the Restatement and the failure by the Company to file SEC reports on a timely basis are unpredictable, and any orders, actions or rulings not in our favor could have a material adverse effect on our financial condition, liquidity or results of operations.

The circumstances which gave rise to the Restatement and the related SEC filing delays continue to create the risk of litigation and claims by investors and examinations, investigations, proceedings and orders by regulatory authorities, which could be expensive and damaging to our business and financial condition.

For example, following the Company’s initial announcement of the Restatement on March 12, 2014, a purported class action was filed against the Company and certain of the Company’s now-former officers. On March 16, 2015, a second amended complaint in this same action was filed against the Company, certain of the Company’s current directors and former and now-former officers, and a stockholder of the Company on behalf of a putative class consisting of all persons other than the defendants who purchased or acquired the Company’s securities between February 1, 2012 and February 12, 2015. The second amended complaint asserts claims for (i) alleged violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder by the Company and certain of the Company’s current directors and former and now-former officers, (ii) alleged violations of Section 20(a) of the Exchange Act by certain of the Company’s current directors and former and now-former officers, and (iii) alleged violations of Sections 20(a) and 20(A) of the Exchange Act by a stockholder.

Similarly, on April 21, 2015, a related purported class action lawsuit was filed against the Company, certain of the Company’s current directors and former and now-former officers, a shareholder of the Company, and certain financial firms that acted as underwriters of the Company’s public stock offerings on behalf of a putative class consisting of all persons other than the defendants who purchased or acquired the Company’s securities between February 1, 2012 and February 12, 2015, including all purchasers of the Company’s common stock pursuant to or traceable to a shelf registration statement and prospectus issued in connection with the Company’s February 6, 2013 public stock offering. The complaint asserts claims for (i) alleged violations of Section 11 of the Securities Act by the Company, certain of the Company’s current directors and former and now-former officers, and certain financial firms that acted as underwriters of the Company’s public stock offerings, (ii) alleged violations of Section 12 of the Securities Act by the Company, certain of the Company’s former and now-former officers, a shareholder of the Company, and certain financial firms that acted as underwriters of the Company’s public stock offerings, (iii) alleged violations of Section 15 of the Securities Act by the Company, certain of the Company’s former and now-former officers, and a shareholder of the Company, (iv) alleged violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder by the Company and certain of the Company’s former and now-former officers, (v) alleged violations of Section 20(a) of the Exchange Act by the Company, certain of the Company’s former and now-former officers, and a shareholder of the Company.

Moreover, a shareholder derivative action, styled Hemmingson et al. v. Elkins et al., Case No. 1-15-cv-278614, was filed in the Superior Court of the State of California in and for Santa Clara County on March 25, 2015, naming as defendants certain of the Company’s current directors and former and now-former officers, as well as a shareholder of the Company, and naming the Company as a nominal defendant. The complaint in this action asserts claims for (i) alleged breaches of fiduciary duty by certain of the Company’s current directors and former and now-former officers for purportedly knowingly failing to maintain adequate internal controls over its accounting and reporting functions and disseminating to shareholders certain alleged materially false and misleading statements, (ii) alleged breaches of fiduciary duty by certain of the Company’s current directors and a current shareholder of the Company for purported insider trading, and (iii) alleged unjust enrichment by a shareholder of the Company for purported insider trading.

Thereafter, on May 13, 2015, a purported shareholder provided notice to the Company and the Board of Directors of a shareholder derivative action styled as Bushansky v. Norby, et al. that the purported shareholder proposes to file in the Superior Court of the State of California, Santa Clara County. The proposed action names as defendants certain of the Company’s current directors and former officers, and a shareholder of the Company, with the Company being named as a nominal defendant. The complaint asserts claims for (i) alleged breaches of fiduciary duties by certain of the Company’s current directors and former officers for knowingly failing to maintain adequate internal controls over the Company’s accounting and reporting functions and disseminating to shareholders certain alleged materially false and misleading statements, and (ii) alleged aiding and abetting of such breaches of fiduciary duties by all defendants.

In addition, in March 2014, the Company voluntarily reported to the SEC that the Audit Committee had determined that the Company incorrectly recognized revenue on certain transactions and as a result would restate its financial statements, and that the Audit Committee had commenced the independent investigation. Over the course of 2014 and in the first quarter of 2015, the Company voluntarily produced documents to the SEC regarding the various accounting issues identified during the independent investigation, and whether the Company’s hiring of an accountant from the Company’s independent registered public accounting firm impacted that accounting firm’s independence. On July 22, 2014, the Staff of the SEC’s Division of Enforcement obtained a Formal Order of Investigation. On March 12, 2015, the SEC issued a subpoena for documents to the Company in connection with its investigation. The Company will continue to cooperate with the SEC in this investigation. See “Item 3. Legal Proceedings.”

The Restatement and the failure by the Company to timely file certain of its SEC reports, as well as the reported material weaknesses in internal control over financial reporting, may subject the Company to a broad range of potential actions that may be taken against the Company by the staff of the SEC, including a cease and desist order, suspension of trading of our securities, deregistration of our securities and/or the assessment of possible civil monetary penalties.

Any orders, actions or rulings relating to any of the foregoing that are not in our favor could have a material adverse effect on our financial condition, liquidity or results of operations.

The events that caused the need for the Restatement and the failure to timely file this Report and certain of our other SEC reports have resulted in certain rating agencies downgrading our credit and debt ratings, and further credit rating downgrades of our debt or financial strength ratings or withdrawal of these ratings are possible. These downgrades or withdrawals could adversely affect our relationships with customers, suppliers and distributors, adversely affect our operating results, and increase our costs of, or reduce our access to, future borrowings.

Rating agencies assign us debt ratings, based in each case on their opinions of the Company’s ability to meet its respective financial obligations.

Our ratings relative to our competitors may affect our competitive position. The Company and its debt securities have been placed on negative credit ratings watch and/or downgraded by certain rating agencies in connection with the events that caused the need for the Restatement and the failure to timely file our 2013 Form 10-K and other SEC reports. These recent developments and any future rating downgrades or withdrawals of ratings may cause reputational damage, which could materially and adversely affect our relationships with our customers, suppliers and distributors, as well as our ability to borrow. At this time we cannot predict what further actions rating agencies may take, or what actions we may take in response, but these downgrades and/or future downgrades and withdrawals could have a material adverse effect on our results of operations, hedging activities, cost of capital and liquidity.

We have incurred and expect to continue to incur significant expenses related to the Restatement, the remediation of deficiencies in our internal control over financial reporting and disclosure controls and procedures, preparation of this Report and our other SEC reports and related investigation and defense costs.

We have devoted and expect to continue to devote substantial internal and external resources to remediation efforts relating to the Restatement and the preparation and filing of the 2013 Form 10-K, this Report and our other SEC reports. As a result of these efforts, we have incurred and expect that we will continue to incur significant incremental fees and expenses for additional auditor services, financial and other consulting services, legal services and additional interest payments, as well as the implementation and maintenance of systems and processes that will need to be updated, supplemented or replaced. These expenses, as well as the substantial time devoted by our management towards identifying and addressing any internal weaknesses and legal defense costs related to the litigation, claims and other actions related to the Restatement, could have a material adverse effect on our business, profitability and financial condition.

The Restatement process has diverted management and other human resources from the operation of our business. The absence of timely and accurate financial information has hindered and may in the future hinder our ability to effectively manage the business of the Company.

The Restatement process has diverted, and continues to divert, management and other human resources from the operation of our business. The Board of Directors, members of management, and the accounting, legal, administrative and other staff of the Company have spent, and continue to spend, significant time on the Restatement, related disclosures and remediation of disclosure controls and procedures and internal control over financial reporting of the Company and its subsidiaries. These resources have been, and will likely continue to be, diverted from the strategic and day-to-day management of our business and may have an adverse effect on our ability to accomplish the strategic objectives of the Company.

The Restatement and the delayed filing of this Report could adversely impact our ability to access the capital markets and other financing arrangements.

Our ability to obtain financing, if needed, depends upon many factors, including our business prospects and creditworthiness as well as external economic conditions and general liquidity in the credit and capital markets. In light of the Restatement and the delay in filing this Report, we may be unable, if needed, to secure outside financing to fund ongoing operations and for other capital needs, including the refinancing of our 2021 Notes if necessary. Any sources of financing that may be available to us could also be at higher costs and require us to satisfy more restrictive covenants, which could limit or restrict our operations, cash flows and earnings. We cannot assure that additional financing would be available to us, or be sufficient or available on satisfactory terms. In addition, unless all current periodic reports and financial statements are filed with the SEC, we will be precluded from registering our securities with the SEC for offer and sale, and the failure to timely file our SEC reports will limit our ability to use “short-form” Form S-3 registration statements for registering our securities for sale with the SEC until we again meet the timely filing requirements of those forms.

Our current credit ratings may also limit our access to external sources of liquidity and financing. Our ongoing needs for liquidity include interest payments on our 2021 Notes and our operating and capital expenses. In addition, we may from time to time have discrete or unexpected needs for liquidity. Our principal sources of liquidity are cash and cash equivalents on hand, cash from operations and financing activities. We do not have in place credit facilities or letters of credit that we could draw upon to meet our liquidity requirements. Without sufficient liquidity, we could be forced to realize investment losses, deplete capital or curtail capital expenditures or certain of our operations, which would adversely impact our results of operations and financial condition.

Risks Related to Our Business

We operate in the highly cyclical semiconductor industry, which is subject to significant downturns that may negatively impact our results of operations.

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change and price erosion, evolving technical standards, short product life cycles (for semiconductors and for the end-user products in which they are used) and wide fluctuations in product supply and demand. From time to time, these and other factors, together with changes in general economic conditions, cause significant upturns and downturns in the industry in general and in our business in particular. Periods of industry downturns have been characterized by diminished demand for end-user products, high inventory levels, underutilization of manufacturing capacity, changes in revenue mix and accelerated erosion of average selling prices. We have experienced these conditions in our business in the past and may experience renewed, and possibly more severe and prolonged, downturns in the future as a result of such cyclical changes. This may reduce our results of operations.

We base our planned operating expenses in part on our expectations of future revenue, and a significant portion of our expenses is relatively fixed in the short term. If revenue for a particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses for that quarter, which would harm our operating results for that quarter.

Our restructuring activities and dispositions of assets and businesses could result in lost business and other costs that could have a material adverse effect on our results of operations.

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 associated with transitioning or eliminating certain employee positions and modifying or terminating vendor relationships in connection with those exit activities.

For example, in December 2014, we announced a plan to close our 6-inch fab, which is expected to be substantially implemented by the end of fiscal year 2015. We currently expect to incur costs associated with customer transition, equipment transfer, clean-up and other costs in the range of $4.0 million to $5.0 million in connection with the closure of the 6-inch fab (excluding potential proceeds from sale of equipment), and incurred a non-cash impairment charge of approximately $10.3 million related to the asset impairment related to such assets. While we currently anticipate transitioning affected employees and certain customers to other production facilities, such activities may result in significant disruption on our business and the loss of customers and revenue during such transition, which could result in lost revenue and have a material adverse effect on our results of operations, both during such transition and after the 6-inch fab closure is completed. In addition, the closure of the 6-inch fab could create management distractions and business disruptions affecting our other manufacturing facilities in connection with the transition, including, among other things, reduced employee morale, increased employee training cost and reduced productivity.

If we fail to develop new products and process technologies or enhance our existing products and services in order to react to rapid technological change and market demands, our business will suffer.

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 must develop new products and services and enhance our existing products and services to meet rapidly evolving customer requirements. We design products for customers who continually require higher performance and functionality at lower costs. We must, therefore, continue to enhance the performance and functionality of our products. The development process for these advancements is lengthy and requires us to accurately anticipate technological changes and market trends. Developing and enhancing these products is uncertain and can be time-consuming, costly and complex. If we do not continue to develop and maintain process technologies that are in demand by our Semiconductor Manufacturing Services customers, we may be unable to maintain existing customers or attract new customers.

21

Index to Financial Statements

Customer and market requirements can change during the development process. There is a risk that these developments and enhancements will be late, fail to meet customer or market specifications or not be competitive with products or services from our competitors that offer comparable or superior performance and functionality. Any new products, such as our expanding line of power management solutions, or product or service enhancements, may not be accepted in new or existing markets. Our business will suffer if we fail to develop and introduce new products and services or product and service enhancements on a timely and cost-effective basis.

We manufacture our products based on our estimates of customer demand, and if our estimates are incorrect, our financial results could be negatively impacted.

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.

Our customers may cancel their orders, reduce quantities or delay production, which would adversely affect our margins and results of operations.

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 depend on high utilization of our manufacturing capacity, a reduction of which could have a material adverse effect on our business, financial condition and the results of our operations.

An important factor in our success is the extent to which we are able to utilize the available capacity in our fabrication facilities. 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, low levels of customer orders, operating inefficiencies, 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 steps could have a material adverse effect on our business, financial condition and results of operations.

A significant portion of our sales comes from a relatively limited number of customers, the loss of which would adversely affect our financial results.

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 or services, our financial results would be adversely affected. For the years ended December 31, 2014, 2013 and 2012, our ten largest customers accounted for 61%, 59% and 61% of our net sales, respectively. For the year ended December 31, 2014, sales to Samsung Display Corporation represented 11.4% of the Company’s net sales and 39.9% of our Display Solutions division’s net sales. For the year ended December 31, 2013, sales to Samsung Display Corporation represented 11.3% of the Company’s net sales and 40.9% of our Display Solutions division’s net sales. For the year ended December 31, 2012, sales to LG Display represented 11.5% of the Company’s net sales and 31.9% of our Display Solutions division’s net sales. 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 or services within a short period of time would adversely affect our business.

The average selling prices of our semiconductor products have at times declined rapidly and will likely do so in the future, which could harm our revenue and gross profit.

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.

Our industry is highly competitive, and our ability to compete could be negatively impacted by a variety of factors.

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 competitors. Some of our competitors are well established as independent companies and have substantially greater market share and manufacturing, financial, research and development and marketing resources than we do. We also compete with emerging companies that are attempting to sell their products in certain of our end markets and with the internal semiconductor design and manufacturing capabilities of many of our significant customers. We expect to experience continuing competitive pressures in our markets from existing competitors and new entrants.

Any consolidation among our competitors could enhance their product offerings and financial resources, further enhancing their competitive position. Our ability to compete will depend on a number of factors, including the following:

Many of these factors are outside of our control. In the future, our competitors may replace us as a supplier to our existing or potential customers, and our customers may satisfy more of their requirements internally. As a result, we may experience declining revenues and results of operations.

Changes in demand for consumer electronics in our end markets can impact our results of operations.

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.

If we fail to achieve design-wins for our semiconductor products, we may lose the opportunity for sales to customers for a significant period of time and be unable to recoup our investments in our products.

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.

We have lengthy and expensive design-to-mass production and manufacturing process development cycles that may cause us to incur significant expenses without realizing meaningful sales, the occurrence of which would harm our business.

The cycle time from the design stage to mass production for some of our products is long and requires the investment of significant resources with many potential customers without any guarantee of sales. Our design-to-mass production cycle typically begins with a three-to-twelve month semiconductor development stage and test period followed by a three-to-twelve month end-product qualification period by our customers. The fairly lengthy front end of our sales cycle creates a risk that we may incur

23

Table of Contents

Index to Financial Statements

significant expenses but may be unable to realize meaningful sales. Moreover, prior to mass production, customers may decide to cancel their products or change production specifications, resulting in sudden changes in our product specifications, increasing our production time and costs. Failure to meet such specifications may also delay the launch of our products or result in lost sales.

In addition, we collaborate and jointly develop certain process technologies and manufacturing process flows customized for certain of our Semiconductor Manufacturing Services customers. To the extent that our Semiconductor Manufacturing Services customers fail to achieve market acceptance for their products, we may be unable to recoup our engineering resources commitment and our investment in process technology development, which would harm our business.

Research and development investments may not yield profitable and commercially viable product and service offerings and thus will not necessarily result in increases in revenues for us.

We invest significant resources in our research and development. Our research and development efforts, however, may not yield commercially viable products or enhance our Semiconductor Manufacturing Services offerings. During each stage of research and development, there is a substantial risk that we will have to abandon a potential product or service offering that is no longer marketable and in which we have invested significant resources. In the event we are able to develop viable new products or service offerings, 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.

We face numerous challenges relating to executing our growth strategy, and if we are unable to execute our growth strategy effectively, our business and financial results could be materially and adversely affected.

Our growth strategy is to leverage our advanced analog and mixed-signal technology platform, continue to innovate and deliver new products and services, increase business with existing customers, broaden our customer base, aggressively grow our power business, drive execution excellence and focus on specialty process technologies. 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.

We are subject to risks associated with currency fluctuations, and changes in the exchange rates of applicable currencies could impact our results of operations.

Historically, a portion of our revenues and greater than the majority of our operating expenses and costs of sales have been denominated in non-U.S. currencies, principally the Korean won, and we expect that this will remain true in the future. Because we report our results of operations in U.S. dollars, changes in the exchange rate between the Korean won and the U.S. dollar could materially impact our reported results of operations and distort period to period comparisons. In particular, because of the difference in the amount of our consolidated revenues and expenses that are in U.S. dollars relative to Korean won, a depreciation in the U.S. dollar relative to the Korean won could result in a material increase in reported costs relative to revenues, and therefore could cause our profit margins and operating income to appear to decline materially, particularly relative to prior periods. The converse is true if the U.S. dollar were to appreciate relative to the Korean won. For example, foreign currency fluctuations had an unfavorable impact on our reported profit margins and operating income from operations for the fiscal years ended December 31, 2014 compared to the fiscal year ended December 31, 2013. Moreover, our foreign currency gain or loss would be affected by changes in the exchange rate between the Korean won and the U.S. dollar as a substantial portion of non-cash translation gain or loss is associated with the intercompany long-term loans to our Korean subsidiary, which is denominated in U.S. dollars. As of December 31, 2014, the outstanding intercompany loan balance including accrued interests between the Korean subsidiary and the Dutch subsidiary was $766 million. As a result of foreign currency fluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent that fluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our investors, the trading price of our stock or the price of the 2021 Notes could be adversely affected.

From time to time, we may engage in exchange rate hedging activities in an effort to mitigate the impact of exchange rate fluctuations. Our Korean subsidiary enters into foreign currency forward and zero cost collar contracts in order to mitigate a portion of the impact of U.S. dollar-Korean won exchange rate fluctuations on our operating results. These foreign currency forward and zero cost collar contracts typically require us to sell specified notional amounts in U.S. dollars and provide us the option to sell specified notional amounts in U.S. dollars during successive months to our counterparty in exchange for Korean won at specified exchange rates. Obligations under these foreign currency forward and zero cost collar contracts must be cash collateralized if our exposure exceeds certain specified thresholds. These forward and zero cost collar contracts may be terminated by the counterparty in a number of circumstances, including if our total cash and cash equivalents is less than $30 million at the end of a fiscal quarter. We cannot assure that any hedging technique we implement will be effective. If our hedging activities are not effective, changes in currency exchange rates may have a more significant impact on our results of operations. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting our Results of Operations” for further details.

The loss of our key employees would materially adversely affect our business, and we may not be able to attract or retain the technical or management employees necessary to compete in our industry.

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

24

Table of Contents

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.

If we encounter future labor problems, we may fail to deliver our products and services in a timely manner, which would adversely affect our revenues and profitability.

As of December 31, 2014, 2,144 employees, or approximately 63% of our employees, were represented by the MagnaChip Semiconductor Labor Union. 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.

We may incur costs to engage in future business combinations or strategic investments, and we may not realize the anticipated benefits of those transactions.

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, potential increases in our indebtedness and contingent liabilities and charges if the acquired company or assets are later determined to be worth less than the amount paid for them in an earlier original acquisition. In addition, our indebtedness may restrict us from making acquisitions that we may otherwise wish to pursue.

The failure to achieve acceptable manufacturing yields could adversely affect our business.

The manufacture 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 manufacture of our products or those of our Semiconductor Manufacturing Services customers, 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 rely on a number of independent subcontractors and the failure of any of these independent subcontractors to perform as required could adversely affect our operating results.

A substantial portion of our net sales are derived from semiconductor devices assembled in packages or on film. The packaging and testing of semiconductors require technical skill and specialized equipment. For the portion of packaging and testing that we outsource, we use subcontractors located in Korea, China, Philippines, Malaysia and Thailand. We rely on these subcontractors to package and test our devices with acceptable quality and yield levels. We could be adversely affected by political disorders, labor disruptions and natural disasters where our subcontractors are located. If our semiconductor packagers and test service providers experience problems in packaging and testing our semiconductor devices, experience prolonged quality or yield problems or decrease the capacity available to us, our operating results could be adversely affected.

We depend on successful parts and materials procurement for our manufacturing processes, and a shortage or increase in the price of these materials could interrupt our operations and result in a decline of revenues and results of operations.

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. We do not have long-term agreements providing for all of these materials; thus, 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, were constrained in recent years due to an increased demand for silicon. Silicon is also a key raw material for solar cells, the demand for which has increased in recent years. Although supplies of silicon have recently improved due to the entrance of additional suppliers and capacity expansion by existing suppliers, we cannot assure that such 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.

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 SEC, as mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, 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. Manufacturers are also required to disclose their efforts to prevent the sourcing of such minerals and metals produced from them. The implementation of these new 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.

We face warranty claims, product return, litigation and liability risks and the risk of negative publicity if our products fail.

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.

In addition, we are exposed to the product liability risk and the risk of negative publicity affecting our customers. Our sales may decline if any of our customers are sued on a product liability claim. We also may suffer a decline in sales from the negative publicity associated with such a lawsuit or with adverse public perceptions in general regarding our customers’ products. Further, if our products are delivered with impurities or defects, we could incur additional development, repair or replacement costs, and our credibility and the market’s acceptance of our products could be harmed.

We could suffer adverse tax and other financial consequences as a result of changes in, or differences in the interpretation of, applicable tax laws.

Our company 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 ability to compete successfully and achieve future growth will depend, in part, on our ability to protect our proprietary technology and know-how, as well as our ability to operate without infringing the proprietary rights of others.

We seek to protect our proprietary technologies and know-how through the use of patents, trade secrets, confidentiality agreements and other security measures. The process of seeking patent protection takes a long time and is expensive. There can be no assurance that patents will issue from pending or future applications or that, if patents issue, they will not be challenged, invalidated or circumvented, or that the rights granted under the patents will provide us with meaningful protection or any commercial advantage. Some of our technologies are not covered by any patent or patent application. The confidentiality agreements on which we rely to protect these technologies may be breached and may not be adequate to protect our proprietary technologies. We cannot assure that other countries in which we market our services will protect our intellectual property rights to the same extent as the United States. 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 United States.

Our ability to compete successfully depends on our ability to operate without infringing the proprietary rights of others. We have no means of knowing what patent applications have been filed in the United States until they are published. In addition, the semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. We may need to file lawsuits to enforce our patents or intellectual property rights, and we may need to defend against claimed infringement of the rights of others. Any litigation could result in substantial costs to us and divert our resources. Despite our efforts in bringing or defending lawsuits, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. In the event of an adverse outcome in any such litigation, we may be required to:

There can be no assurance that we would be successful in such development or acquisition or that such licenses would be available under reasonable terms, or at all. The termination of key third-party licenses relating to the use of intellectual property in our products and our design processes, such as our agreements with Silicon Works Co., Ltd. and ARM Limited, would materially and adversely affect our business.

Our competitors may develop, patent or gain access to know-how and technology similar to our own. In addition, many of our patents are subject to cross licenses, several of which are with our competitors.

Our expenses could increase if SK Hynix were unwilling or unable to provide certain services related to our shared facilities with SK Hynix, and if SK Hynix were to become insolvent, we could lose certain of our leases.

We are party to a land lease and easement agreement with SK Hynix pursuant to which we lease the land for our facilities in Cheongju, Korea. If this agreement were terminated for any reason, including the insolvency of SK Hynix, we would have to renegotiate new lease terms with SK Hynix or the new owner of the land. We cannot assure that we will be able to negotiate new lease terms on favorable terms or at all. Because we share certain facilities with SK Hynix, several services that are essential to our business are provided to us by or through SK Hynix under our general service supply agreement with SK Hynix. These services include electricity, bulk gases and de-ionized water, campus facilities and housing, wastewater and sewage management, environmental safety and certain utilities and infrastructure support services. If any of our agreements with SK Hynix were terminated or if SK Hynix were unwilling or unable to fulfill its obligations to us under the terms of these agreements, we would have to procure these services on our own and as a result may experience an increase in our expenses.

We are subject to many environmental laws and regulations that could affect our operations or result in significant expenses.

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. 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.

Our Korean subsidiary has been designated as a regulated business under Korean environmental law, and such designation could have an adverse effect on our financial position and results of operations.

In April 2010, the Korean government’s Enforcement Decree to the Framework Act on Low Carbon Green Growth became effective. Certain designated businesses, including our Korean subsidiary, were required to submit plans to reduce greenhouse emissions and energy consumption. Our Korean subsidiary first set emissions and consumption targets in 2011 and negotiated an implementation plan with Korean governmental authorities. Each year thereafter, our Korean subsidiary was required to agree on emissions and consumption targets with Korean governmental authorities and submit an independently verified report of prior year’s compliance. Beginning in 2015, our Korean subsidiary became subject to K-ETS, a new set of greenhouse gas emissions regulation, 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 is required to meet its allocated target by either reducing the emission or purchasing the allowances from other

27

participants 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.

We may need additional capital in the future, and such capital may not be available on acceptable terms or at all, which would have a material adverse effect on our business, financial condition and results of operations.

We may require more capital in the future from equity or debt financings to fund operating expenses, such as research and development costs, finance investments in equipment and infrastructure, acquire complementary businesses and technologies, and respond to competitive pressures and potential strategic opportunities. If we raise additional funds through further issuances of equity or other securities convertible into equity, our existing stockholders could suffer significant dilution, and any new shares we issue could have rights, preferences or privileges senior to those of the holders of our common stock. Also, additional capital may not be available when needed or, if available, may not be available on favorable terms. In addition, our indebtedness limits our ability to incur additional indebtedness under certain circumstances. If we are unable to obtain capital on favorable terms, or if we are unable to obtain capital at all, we may have to reduce our operations or forego opportunities, and this may have a material adverse effect on our business, financial condition and results of operations.

Our business depends on international customers, suppliers and operations in Asia, and as a result we are subject to regulatory, operational, financial and political risks, which could adversely affect our financial results.

We rely on, and expect to continue to rely on, suppliers, subcontractors and operations located primarily in Asia. As a result, we face risks inherent in international operations, such as unexpected changes in regulatory requirements, tariffs and other market barriers, political, social and economic instability, adverse tax consequences, war, civil disturbances and acts of terrorism, difficulties in accounts receivable collection, extended payment terms and differing labor standards, enforcement of contractual obligations and protection of intellectual property. These risks may lead to increased costs or decreased revenue growth, or both. Although we do not derive any revenue from, nor sell any products in, North Korea, any future increase in tensions between South Korea and North Korea that may occur, such as an outbreak of military hostilities, would adversely affect our business, financial condition and results of operations.

Tensions with North Korea could have an adverse effect on us and the market value of our shares.

Relations between South Korea and North Korea have been tense throughout Korea’s modern history. The level of tension between the two Koreas has fluctuated and may increase abruptly as a result of current and future events. In particular, since the death of Kim Jong-il, the former North Korean ruler, in mid-December 2011, there has been increased uncertainty with respect to the future of North Korea’s political leadership and concern regarding its implications for political and economic stability in the region. In addition, in recent years, there have been heightened security concerns stemming from North Korea’s nuclear weapon and long-range missile programs and increased uncertainty regarding North Korea’s actions and possible responses from the international community. North Korea’s economy also faces severe challenges, and any adverse economic developments may further aggravate social and political tensions within North Korea.

Although we do not derive any revenue from, nor sell any products in, North Korea, any future increase in tensions between South Korea and North Korea that may occur, for example, if North Korea experiences a leadership crisis, high-level contacts between South Korea and North Korea break down, or military hostilities occur, could have a material adverse effect on the South Korean economy and on our business, financial condition, results of operations and the market value of our common stock.

You may not be able to bring an action or enforce any judgment obtained in United States courts, or bring an action in any other jurisdiction, against us or our subsidiaries or our directors, officers or independent auditors that are organized or residing in jurisdictions other than the United States.

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

Our level of indebtedness is substantial, and we may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful. A decline in the ratings of our existing or future indebtedness may make the terms of any new indebtedness we choose to incur more costly.

As of December 31, 2014, our total indebtedness was $224.0 million, net of unamortized discount of $1.0 million. We are permitted under the indenture governing our outstanding 2021 Notes to incur additional debt under certain conditions, including additional secured debt. If new debt were to be incurred in the future, the related risks that we now face could intensify. Our substantial debt could have important consequences, including:

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We cannot assure that we will generate a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

The credit ratings assigned to our debt reflect each rating agency’s opinion of our ability to make payments on the debt obligations when such payments are due. The rating of our outstanding 2021 Notes as of April 2015 is Caa1 by Moody’s and B- by Standard and Poor’s, both of which are below investment grade. A rating may be subject to revision or withdrawal at any time by the assigning rating agency. We may experience downgrades in our debt ratings in the future. Any lowering of our debt ratings would adversely impact our ability to raise additional debt financing and increase the cost of any such financing that is obtained. In the event any ratings downgrades are significant, we may choose not to incur new debt or refinance existing debt if we are unable to incur or refinance such debt at favorable interest rates or on favorable terms.

If our cash flows and capital resources are insufficient to fund our debt service obligations or if we are unable to refinance existing indebtedness on favorable terms, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital or restructure or refinance our indebtedness. These alternative measures may not be successful and thus render us unable to meet our scheduled debt service obligations. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. The indenture governing our outstanding 2021 Notes restricts our ability to dispose of assets and use the proceeds from the disposition. We may not be able to consummate those dispositions or be able to obtain the proceeds which we could realize from them and these proceeds may not be adequate to meet any debt service obligations then due.

We are a holding company and will depend on the business of our subsidiaries to satisfy our obligations under our outstanding 2021 Notes and other obligations.

We are a holding company with no independent operations of our own. Our subsidiaries conduct substantially all of the operations necessary to fund payments on our outstanding 2021 Notes, other debt and any other obligations. Our ability to make payments on our outstanding 2021 Notes and our other obligations will depend on our subsidiaries’ cash flow and their payment of funds to us. Our subsidiaries’ ability to make payments to us will depend on:

We cannot assure that the operating results of our subsidiaries at any given time will be sufficient to make distributions or other payments to us or that any distributions or payments will be adequate to pay principal and interest, and any other payments, on our outstanding 2021 Notes, other debt or any other obligations when due, and the failure to make such payments could have a material adverse effect on our business, financial condition and results of operations.

Restrictions on MagnaChip Korea’s ability to make payments on its intercompany loans from MagnaChip Semiconductor B.V., or on its ability to pay dividends in excess of statutory limitations, could hinder our ability to make payments on our outstanding 2021 Notes.

We anticipate that payments under our outstanding 2021 Notes will be funded in part by MagnaChip Korea’s repayment of its existing loans from MagnaChip Semiconductor B.V., with MagnaChip Semiconductor B.V. using such repayments in turn to repay the loans owed to MagnaChip Semiconductor S.A., which will repay loans owed to us. Under the Korean Foreign Exchange Transaction Act, the minister of the Ministry of Strategy and Finance is authorized to temporarily suspend payments in foreign currencies in the event of natural calamities, wars, conflicts of arms, grave and sudden changes in domestic or foreign economic conditions, or other similar situations. In addition, under the Korean Commercial Code, a Korean company is permitted to make a dividend payment in accordance with the provisions in its articles of incorporation out of retained earnings (as determined in accordance with the Korean Commercial Code and the generally accepted accounting principles in Korea), but no more than twice a year. If MagnaChip Korea is prevented from making payments under its intercompany loans due to restrictions on payments of foreign currency or if it has an insufficient amount of retained earnings under the Korean Commercial Code to make dividend payments to MagnaChip Semiconductor B.V., we may not have sufficient funds to make payments on our outstanding 2021 Notes.

The indenture governing our outstanding 2021 Notes contains, and our future debt agreements will likely contain, covenants that significantly restrict our operations.

The indenture governing our outstanding 2021 Notes contains, and our future debt agreements will likely contain, numerous covenants imposing financial and operating restrictions on our business. These restrictions may affect our ability to operate our business, may limit our ability to take advantage of potential business opportunities as they arise and may adversely affect the conduct of our current business, including by restricting our ability to finance future operations and capital needs and by limiting our ability to engage in other business activities. These covenants will place restrictions on our ability and the ability of our operating subsidiaries to, among other things:

In addition, our future debt agreements will likely contain financial ratios and other financial conditions tests. Our ability to meet those financial ratios and tests could be affected by events beyond our control, and we cannot assure that we will meet those ratios and tests. A breach of any of these covenants could result in a default under such debt agreements. Upon the occurrence of an event of default under such debt agreements, our lenders under such agreements could elect to declare all amounts outstanding under such debt agreements to be immediately due and payable and terminate all commitments to extend further credit.

The global downturn and related financial crisis negatively affected our business. Poor economic conditions may negatively affect our future business, results of operations and financial condition.

The global downturn and related financial crisis that started in 2008 led to slower economic activity, increased unemployment, concerns about inflation and energy costs, decreased business and consumer confidence, reduced corporate profits and capital spending, adverse business conditions and lower levels of liquidity in many financial markets. Consumers and businesses deferred purchases in response to tighter credit and negative financial news, which has in turn negatively affected product demand and other related matters. The global downturn led to reduced customer spending in the semiconductor market and in our target markets, made it

difficult for our customers, our vendors and us to accurately forecast and plan future business activities and caused U.S. and foreign businesses to slow spending on our products. Although economic conditions have improved generally and in the semiconductor industry specifically, we cannot assure the extent to which such conditions will continue to improve or whether the improvement will be sustainable. If the global economic recovery is not sustained or the global economy experiences another recession, such adverse economic conditions could lead to the insolvency of key suppliers resulting in product delays, limit the ability of customers to obtain credit to finance purchases of our products, lead to customer insolvencies and also result in counterparty failures that may negatively impact our treasury operations. As a result, our business, financial condition and results of operations could be materially adversely affected in future periods as a result of economic downturns.

We have a history of losses and may not achieve or sustain profitability in the future.

From the time we began operations as a separate entity in 2004 until we emerged from reorganization proceedings in 2009, we generated significant net losses and did not generate a profit for a full fiscal year. We may increase spending to support increased research and development and sales and marketing efforts. These expenditures may not result in increased revenue or an increase in the number of customers immediately or at all. 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. If we cannot maintain profitability, the value of the enterprise may decline.

Investor confidence may be adversely impacted if we fail to remediate identified material weaknesses and maintain effective internal control over financial reporting and disclosure controls and procedures or are unable to comply with Section 404 of the Sarbanes-Oxley Act, and as a result, the value of our securities could decline.

We are subject to rules adopted by the SEC pursuant to Section 404 of the Sarbanes-Oxley Act, which requires us to include in our Annual Report on Form 10-K our management’s report on, and assessment of the effectiveness of, our internal control over financial reporting. We are also required to periodically assess and report on the adequacy of our disclosure controls and procedures. As reported in “Item 9A. Controls and Procedures” of this Report, we have concluded that there are material weaknesses in our internal control over financial reporting and that our disclosure controls and procedures were ineffective as of December 31, 2014.

If we fail to remediate identified material weaknesses and maintain the effectiveness of our internal control over financial reporting, there is a risk that we will continue to have material weaknesses in the future. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. Any of these possible outcomes could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our consolidated financial statements and could result in investigations or sanctions by the SEC, the NYSE or other regulatory authorities or in stockholder litigation. Any of these factors ultimately could harm our business and could negatively impact the market price of our securities. Ineffective control over financial reporting could also cause investors to lose confidence in our reported financial information, which could adversely affect the trading price of our common stock.

Our goal is to ensure that our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, with the participation of our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. However, our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. See “Item 9A. Controls and Procedures.”

We may need to incur impairment and other restructuring charges, which could materially affect our results of operations and financial condition.

During industry downturns and for other reasons, we may need to record impairment or restructuring charges. From November 9, 2009, the date we emerged from Chapter 11 reorganization proceedings, through December 31, 2014, we recognized aggregate restructuring and impairment charges of $24.6 million, which consisted of $21.2 million of impairment charges and $3.4 million of restructuring charges. For the year ended December 31, 2014, we recognized $10.3 million of impairment charges related to the closure of our 6-inch fab. 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.

We are subject to litigation risks, which may be costly to defend and the outcome of which is uncertain.

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. 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. Even if the final outcome of these legal claims does not have a material adverse effect on our financial position, results of operations or cash flows, defense and settlement costs can be substantial. Due to the inherent uncertainty of the litigation process, the resolution of any particular legal claim or proceeding could have a material effect on our business, financial condition, results of operations or cash flows.

The price of our common stock may be volatile and you may lose all or a part of your investment.

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:

In the past, following periods of volatility in the market price of a public company’s securities, securities class action litigation often has been instituted against the public company. Regardless of its outcome, this type of litigation could result in substantial costs to us and a likely diversion of our management’s attention. You may not receive a positive return on your investment when you sell your shares, and you could lose some or the entire amount of your investment.

Significant ownership of our common stock by certain stockholders could adversely affect our other stockholders.

Based upon the number of shares of common stock outstanding as of May 1, 2015, our executive officers, directors and Avenue collectively beneficially owned approximately 12.4% of our common stock, excluding shares of common stock issuable upon exercise of outstanding options, and 14.7% of our common stock, including shares of common stock issuable upon exercise of outstanding options that are exercisable within sixty days of May 1, 2015. In addition, affiliates of Avenue currently have two employees serving as members of our seven-member Board of Directors. Therefore, Avenue will continue to have significant influence over our affairs for the foreseeable future, including influence over the election of directors and significant corporate transactions, such as a merger or other sale of our company or our assets.

Our concentration of ownership 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, our 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.

Under our certificate of incorporation, our non-employee directors and non-employee holders of five percent or more of our outstanding common stock do not have a duty to refrain from engaging in a corporate opportunity in the same or similar activities or lines of business as those engaged in by us, our subsidiaries and other related parties. Also, we have renounced any interest or expectancy in such business opportunities even if the opportunity is one that we might reasonably have pursued or had the ability or desire to pursue if granted an opportunity to do so.

Future sales of significant amounts of our common stock could negatively affect our stock price, even if our business is doing well.

As of May 1, 2015, Avenue beneficially owned 4,088,978 shares, or approximately 12.0%, of our outstanding common stock. On November 9, 2014, all warrants to purchase our common stock previously held by Avenue expired. All of our currently outstanding shares that were issued pursuant to Section 1145 of the United States Bankruptcy Code, including Avenue’s shares, are

32

Table of Contents

eligible for sale from time to time under Rule 144 or Section 4(a)(1) of the Securities Act subject only to the limitations on affiliate sales. Additionally, all remaining shares beneficially owned by Avenue are or will be registered for resale under a shelf registration statement and therefore be eligible for sale at any time or from time to time by Avenue. If any of our current stockholders, including Avenue, sells or is perceived by the market as intending to sell substantial amounts of our common stock, the market price of our common stock could drop significantly, even if our business is doing well.

Our Rights Plan and provisions in our charter documents and Delaware Law may make it difficult for a third party to acquire us and could depress the price of our common stock.

On March 6, 2015, our Board of Directors adopted a stockholder rights plan (the “Rights Plan”) and declared a dividend of one preferred stock purchase right on each share of the Company’s common stock outstanding at the close of business on March 16, 2015. Each right will entitle the holder to purchase one one-thousandth of a share of our Series A Junior Participating Preferred Stock. Under certain circumstances, if a person or group acquires 10% (or 20% in the case of a passive institutional investor) or more of our outstanding common stock, holders of the rights (other than the person or group triggering their exercise) will be able to purchase for each share of common stock owned, $24 worth of shares of the Company’s common stock having a market value of twice such price. The rights expire in March 2016 unless extended by our Board of Directors. Because the rights may substantially dilute the stock ownership of a person or group attempting to acquire us without the approval of our Board of Directors, our rights plan could make it more difficult for a third party to acquire us (or a significant percentage of our outstanding capital stock) without first negotiating with our Board of Directors regarding such acquisition.

In addition, 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:

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), regulating corporate takeovers and which has an anti-takeover effect with respect to transactions not approved in advance by our Board of Directors, including discouraging takeover attempts that might result in a premium over the market price for shares of our common stock. In general, those provisions prohibit a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

In general, DGCL Section 203 defines a business combination to include the following:

33

Table of Contents

Index to Financial Statements

In general, DGCL Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by any such entity or person.

A Delaware corporation may opt out of this provision by express provision in its original certificate of incorporation or by amendment to its certificate of incorporation or bylaws approved by its stockholders. However, we have not opted out of, and do not currently intend to opt out of, this provision.

We do not intend to pay dividends for the foreseeable future, and therefore, investors should rely on sales of their common stock as the only way to realize any future gains on their investments.

We do not intend to pay any cash dividends in the foreseeable future. The payment of cash dividends on common stock is restricted under the terms of the indenture for our outstanding 2021 Notes. Any determination to pay dividends in the future will be at the discretion of our Board of Directors. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Item 2. Properties

Our manufacturing operations consist of three fabrication facilities located in Korea at two sites in Cheongju and one in Gumi. Our facilities have a combined capacity of approximately 127,597 eight-inch equivalent wafers per month. We manufacture wafers utilizing geometries ranging from 0.11 to 2.0 microns. The Cheongju facilities have three main buildings totaling 164,058 square meters devoted to manufacturing and development. The Gumi facility has one main building with 41,022 square meters devoted to manufacturing, testing and packaging.

In addition to our fabrication facilities, we lease facilities in Seoul, Korea, and Cupertino, California. Each of these facilities includes administration, sales and marketing and research and development functions. We lease sales and marketing offices through our subsidiaries in several other countries.

The ownership of our wafer manufacturing assets is an important component of our business strategy. Maintaining manufacturing control enables us to develop proprietary, differentiated products and results in higher production yields, as well as shortened design and production cycles. We believe our facilities are suitable and adequate for the conduct of our business for the foreseeable future and that we have sufficient production capacity to service our business as currently contemplated without significant capital investment.

A substantial majority of our assembly, test and packaging services for our Display Solutions business and all of such services for our Power Solutions business are outsourced with the balance handled in-house. Our independent providers of these services are located in Korea, China, Philippines, Malaysia and Thailand. The relative cost of outsourced services, as compared to in-house services, depends upon many factors specific to each product and circumstance. However, we generally incur higher costs for outsourced services, which can result in lower margins.

Although we own our manufacturing facilities, we are party to a land lease and easement agreement with SK Hynix pursuant to which we lease the land for our facilities in Cheongju, Korea from SK Hynix for an indefinite term. Because we share certain facilities with SK Hynix, several services that are essential to our business are provided to us by or through SK Hynix under our general service supply agreement with SK Hynix. These services include electricity, bulk gases and de-ionized water, campus facilities and housing, wastewater and sewage management, environmental safety and certain utilities and infrastructure support services. The services agreement continues for an indefinite term subject to each party having a right to terminate in the event of an uncured breach by the other party.

Item 3. Legal Proceedings

Securities Class Action Complaints

On March 12, 2014, a purported class action was filed against the Company and certain of the Company’s now-former officers. On March 16, 2015, a second amended complaint in this same action was filed against the Company, certain of the Company’s current directors and former and now-former officers, and a stockholder of the Company on behalf of a putative class consisting of all persons other than the defendants who purchased or acquired the Company’s securities between February 1, 2012 and March 12, 2015. The second amended complaint asserts claims for (i) alleged violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder by the Company and certain of the Company’s current directors and former and now-former officers, (ii) alleged violations of Section 20(a) of the Exchange Act by certain of the Company’s current directors and former and now-former officers, and (iii) alleged violations of Sections 20(a) and 20(A) of the Exchange Act by a stockholder. The action, Thomas et al., v. MagnaChip Semiconductor Corp., et al., No. 3:14-cv-1160, is pending in the Northern District of California.

On April 21, 2015, a related purported class action lawsuit was filed against the Company, certain of the Company’s current directors and former and now-former officers, a shareholder of the Company, and certain financial firms that acted as underwriters of the Company’s public stock offerings on behalf of a putative class consisting of all persons other than the defendants who purchased or acquired the Company’s securities between February 1, 2012 and February 12, 2015, including all purchasers of the Company’s common stock pursuant to or traceable to a shelf registration statement and prospectus issued in connection with the Company’s February 6, 2013 public stock offering. The complaint asserts claims for (i) alleged violations of Section 11 of the Securities Act by the Company, certain of the Company’s current directors and former and now-former officers, and certain financial firms that acted as underwriters of the Company’s public stock offerings, (ii) alleged violations of Section 12 of the Securities Act by the Company, certain of the Company’s former and now-former officers, a shareholder of the Company, and certain financial firms that acted as underwriters of the Company’s public stock offerings, (iii) alleged violations of Section 15 of the Securities Act by the Company, certain of the Company’s former and now-former officers, and a shareholder of the Company, (iv) alleged violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder by the Company and certain of the Company’s former and now-former officers, (v) alleged violations of Section 20(a) of the Exchange Act by the Company, certain of the Company’s former and now-former officers, and a shareholder of the Company. The action, Okla. Police Pension & Retirement Sys. v. MagnaChip Semiconductor Corp., et al., No. 3:15-cv-01797, is pending in the Northern District of California. A motion to consolidate Okla. Police Pension & Retirement Sys. v. MagnaChip Semiconductor Corp., et al., No. 3:15-cv-01797 and Thomas et al., v. MagnaChip Semiconductor Corp., et al., No. 3:14-cv-1160 is also pending. At this time, the Company is unable to estimate any reasonably possible loss, or range of reasonably possible losses, with respect to the matters described above. This is primarily because these matters involve complex legal and factual issues subject to uncertainty. There can be no assurance that these matters will be resolved in a manner that is not adverse to the Company.

SEC Enforcement Staff Review

In addition, in March 2014, the Company voluntarily reported to the SEC that the Audit Committee had determined that the Company incorrectly recognized revenue on certain transactions and as a result would restate its financial statements, and that the Audit Committee had commenced the independent investigation. Over the course of 2014 and in the first quarter of 2015, the Company voluntarily produced documents to the SEC regarding the various accounting issues identified during the independent investigation, and whether the Company’s hiring of an accountant from the Company’s independent registered public accounting firm impacted that accounting firm’s independence. On July 22, 2014, the Staff of the SEC’s Division of Enforcement obtained a Formal Order of Investigation. On March 12, 2015, the SEC issued a subpoena for documents to the Company in connection with this investigation. The Company will continue to cooperate with the SEC in this investigation. At this time, the Company is unable to estimate any reasonably possible loss, or range of reasonably possible losses, with respect to the matters described above. This is primarily because these matters involve complex legal and factual issues subject to uncertainty. There can be no assurance that these matters will be resolved in a manner that is not adverse to the Company.

Shareholder Derivative Complaints

A shareholder derivative action, styled Hemmingson et al. v. Elkins et al., Case No. 1-15-cv-278614, was filed in the Superior Court of the State of California in and for Santa Clara County on March 25, 2015, naming as defendants certain of the Company’s current directors and former and now-former officers, as well as a shareholder of the Company, and naming the Company as a nominal defendant. The complaint in this action asserts claims for (i) alleged breaches of fiduciary duty by certain of the Company’s current directors and former and now-former officers for purportedly knowingly failing to maintain adequate internal controls over its accounting and reporting functions and disseminating to shareholders certain alleged materially false and misleading statements, (ii) alleged breaches of fiduciary duty by certain of the Company’s current directors and a current shareholder of the Company for purported insider trading, and (iii) alleged unjust enrichment by a shareholder of the Company for purported insider trading. On May 13, 2015, the court so ordered a stipulation entered into by certain of the parties, agreeing to stay the litigation until Thomas et al., v. MagnaChip Semiconductor Corp., et al., No. 3:14-cv-1160 and Okla. Police Pension & Retirement Sys. v. MagnaChip Semiconductor Corp., et al., No. 3:15-cv-01797 are resolved, unless the stay is lifted earlier.

On May 13, 2015, a purported shareholder provided notice to the Company and the Board of Directors of a shareholder derivative action styled as Bushansky v. Norby, et al. that the purported shareholder proposes to file in the Superior Court of the State of California, Santa Clara County. The proposed action names as defendants certain of the Company’s current directors and former officers, and a shareholder of the Company, with the Company being named as a nominal defendant. The complaint asserts claims for (i) alleged breaches of fiduciary duties by certain of the Company’s current directors and former officers for knowingly failing to maintain adequate internal controls over the Company’s accounting and reporting functions and disseminating to shareholders certain alleged materially false and misleading statements; and (ii) alleged aiding and abetting of such breaches of fiduciary duties by all defendants. At this time, the Company is unable to estimate any reasonably possible loss, or range of reasonably possible losses, with respect to the matters described above. This is primarily because these matters involve complex legal and factual issues subject to uncertainty. There can be no assurance that these matters will be resolved in a manner that is not adverse to the Company.

Other Legal Proceedings

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 ordinary-course legal proceedings that we believe would have a material adverse effect on our business, financial condition or results of operations.

Holders

The approximate number of record holders of our outstanding common stock as of May 1, 2015 was 83. This number does not include beneficial owners for whom shares are held by nominees in street name.

Dividends

We do not intend to pay any cash dividends on our common stock in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our Board of Directors. The payment of cash dividends on our common stock is restricted under the terms of the indenture governing our 2021 Notes.

Issuer Purchases of Equity Securities

On October 7, 2011, our Board of Directors adopted a stock repurchase program whereby we may, subject to prevailing market conditions and other factors, repurchase up to $35.0 million of our outstanding common stock. Our Board of Directors extended and increased the program by an additional $25.0 million in August 2012, for a maximum aggregate repurchase amount under the original program of up to $60.0 million. On July 30, 2013, we announced that our Board of Directors approved a new stock repurchase program under which we are authorized to repurchase up to $100.0 million of our common stock. The new stock repurchase program was effective August 5, 2013 through December 15, 2014, and replaced the original stock repurchase program. The stock repurchase program did not require that we purchase a minimum amount of shares of our common stock and may be commenced, suspended, resumed or terminated at any time without notice. The timing and extent of any repurchases were dependent upon prevailing market conditions, the trading price of the Company’s common stock and other factors, and subject to contractual restrictions and restrictions under applicable law and regulations. As of December 31, 2013, we had repurchased 6,578,765 shares of our common stock in the open market under these programs at an aggregate cost of $90.9 million. In March 2014, our Board of Directors suspended the stock repurchase program indefinitely pending the completion of the independent investigation, and the stock repurchase program expired by its terms on December 15, 2014. Subsequent to December 31, 2013, we did not repurchase any shares under the stock repurchase program.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the audited consolidated financial statements and unaudited consolidated interim financial statements, together in each case with the related notes, included elsewhere in this Report. This discussion and analysis contains, in addition to historical information, forward-looking statements that include risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under the heading “Risk Factors” and elsewhere in this Report.

Overview

We are a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products for consumer, computing, communication, industrial, automotive and IoT applications. We provide technology platforms for analog, mixed-signal, power, high voltage, non-volatile memory, and RF applications. We have a proven record with a 30-year operating history, large portfolio of approximately 2,917 registered novel patents and 141 pending novel patent applications and extensive engineering and manufacturing process expertise. Our business is comprised of three key business lines: Display Solutions, Power Solutions and Semiconductor Manufacturing Services. Our Display Solutions products provide flat panel display solutions to major suppliers of large and small flat panel display. Our Power Solutions products include discrete and integrated circuit solutions for power management in consumer, computing, communication and industrial applications. Our Semiconductor Manufacturing Services provide specialty analog and mixed-signal foundry services mainly for fabless and IDM semiconductor companies that primarily serve the consumer, computing, communication, industrial, automotive and IoT applications.

Our wide variety of analog and mixed-signal semiconductor products and manufacturing services combined with our mature technology platform allow us to address multiple high-growth end markets and to rapidly develop and introduce new products and services in response to market demands. Our design center and substantial manufacturing operations in Korea place us at the core of the global electronics device supply chain. We believe this enables us to quickly and efficiently respond to our customers’ needs and allows us to better serve and capture additional demand from existing and new customers.

To maintain and increase our profitability, we must accurately forecast trends in demand for electronics devices that incorporate semiconductor products we produce. We must understand our customers’ needs as well as the likely end market trends and demand in the markets they serve. We must balance the likely manufacturing utilization demand of our product businesses and foundry business to optimize our capacity utilization. We must also invest in relevant research and development activities and manufacturing capacity and purchase necessary materials on a timely basis to meet our customers’ demand while maintaining our target margins and cash flow.

The semiconductor markets in which we participate are highly competitive. The prices of our products tend to decrease regularly over their useful lives, and such price decreases can be significant as new generations of products are introduced by us or our competitors. We strive to offset the impact of declining selling prices for existing products through cost reductions and the introduction of new products that command selling prices above the average selling price of our existing products. In addition, we seek to manage our inventories and manufacturing capacity so as to mitigate the risk of losses from product obsolescence.

Demand for our products and services is driven by overall demand for consumer, communication and computing products and can be adversely affected by periods of weak consumer and enterprise spending or by market share losses by our customers. In order to mitigate the impact of market volatility on our business, we are diversifying our portfolio of products, customers, and target applications. We also expect that new competitors will emerge in these markets that may place increased pressure on the pricing for our products and services. While we believe we are well-positioned competitively to compete in these markets and against these new competitors as a result of our long operating history, existing manufacturing capacity and our Korea-based operations, if we are not effective in competing in these markets our operating results may be adversely affected.

Within our Display Solutions and Power Solutions lines, net sales are driven by design wins in which we are selected by an electronics OEM or other potential customer to supply its demand for a particular product. A customer will often have more than one supplier designed in to multi-source components for a particular product line. Once we have design wins and the products enter into mass production, we often specify the pricing of a particular product for a set period of time, with periodic discussions and renegotiations of pricing with our customers. In any given period, our net sales depend heavily upon the end-market demand for the goods in which our products are used, the inventory levels maintained by our customers and in some cases, allocation of demand for components for a particular product among selected qualified suppliers.

Within the Semiconductor Manufacturing Services business, net sales are driven by customers’ decisions on which manufacturing services provider to use for a particular product. Most of our Semiconductor Manufacturing Services customers are fabless, while some are IDM customers. A customer will often have more than one supplier of manufacturing services. In any given period, our net sales

depend heavily upon the end-market demand for the goods in which the products we manufacture for customers are used, the inventory levels maintained by our customers and, in some cases, allocation of demand for manufacturing services among selected qualified suppliers.

In contrast to fabless semiconductor companies, our internal manufacturing capacity provides us with greater control over manufacturing costs and the ability to implement process and production improvements which can favorably impact gross profit margins. Our internal manufacturing capacity also allows for better control over delivery schedules, improved consistency over product quality and reliability and improved ability to protect intellectual property from misappropriation. However, having internal manufacturing capacity exposes us to the risk of under-utilization of manufacturing capacity that results in lower gross profit margins, particularly during downturns in the semiconductor industry.

Our products and services require investments in capital equipment. Analog and mixed-signal manufacturing facilities and processes are typically distinguished by the design and process implementation expertise rather than the use of the most advanced equipment. These processes also tend to migrate more slowly to smaller geometries due to technological barriers and increased costs. For example, some of our products use high-voltage technology that requires larger geometries and that may not migrate to smaller geometries for several years, if at all. Additionally, the performance of many of our products is not necessarily dependent on geometry. As a result, our manufacturing base and strategy do not require substantial investment in leading edge process equipment, allowing us to utilize our facilities and equipment over an extended period of time with moderate required capital investments. Generally, incremental capacity expansions in our business line of the market result in more moderate industry capacity expansion as compared to leading edge processes. As a result, this market, and we, specifically, are less likely to experience significant industry overcapacity, which can cause product prices to decline significantly. In general, we seek to invest in manufacturing capacity that can be used for multiple high-value applications over an extended period of time. We believe this capital investment strategy enables us to optimize our capital investments and facilitates deeper and more diversified product and service offerings.

Our success going forward will depend upon our ability to adapt to future challenges such as the emergence of new competitors for our products and services or the consolidation of current competitors. Additionally, we must innovate to remain ahead of, or at least rapidly adapt to, technological breakthroughs that may lead to a significant change in the technology necessary to deliver our products and services. We believe that our established relationships and close collaboration with leading customers enhance our visibility into new product opportunities, market and technology trends and improve our ability to meet these challenges successfully. In our Semiconductor Manufacturing Services business, we strive to maintain competitiveness and our position as a primary manufacturing services provider to our customers by offering high-value added processes, high-flexibility and excellent service by tailoring existing standard processes to meet customers’ design needs and porting customers’ own process technologies into our fabrication facilities.

Other Significant Events

In January 2014, our Audit Committee commenced an internal investigation that resulted in the Restatement of certain financial statements for prior periods. As a result of the Restatement, we have incurred substantial accounting, legal and other related costs associated with the Restatement and certain litigation and other regulatory investigations and actions related thereto. We incurred Restatement related costs of $40.9 million for the year ended December 31, 2014, where there were no similar costs in 2013 or 2012. We expect to continue to incur substantial Restatement related costs in 2015 related to ongoing litigation and regulatory investigations, which could have a material adverse effect on our operating results and liquidity for the foreseeable future. See “—Liquidity and Capital Resources”

On September 13, 2013, we closed an underwritten registered public offering of 1,700,000 shares of our common stock owned by certain of our stockholders at a price per share of $21.20. We did not receive any proceeds from the sale of our common stock by the selling stockholders but paid certain expenses in connection with such secondary offering.

On July 18, 2013, we issued the 2021 Notes, at a price of 99.5%. Interest on the 2021 Notes accrues at a rate of 6.625% per annum, payable semi-annually on January 15 and July 15 of each year, beginning on January 15, 2014. We used net proceeds of the 2021 Notes, together with cash on hand, to repay all of our then outstanding 10.5% senior notes due April 15, 2018 (the “2018 Notes”), including applicable premium and accrued interest, and to pay related fees and expenses of the 2021 Notes offering.

On February 8, 2013, we closed an underwritten registered public offering of 5,750,000 shares of our common stock owned by certain of our stockholders at a price per share of $14.50. We did not receive any proceeds from the sale of our common stock by the selling stockholders but paid certain expenses in connection with such secondary offering.

On May 1, 2012, we closed an underwritten registered public offering of 7,000,000 shares of our common stock owned by certain of our stockholders at a price per share of $11.40. We did not receive any proceeds from the sale of our common stock by the selling stockholders but paid certain expenses in connection with such secondary offering.

Explanation and Reconciliation of Non-US GAAP Measures

Adjusted EBITDA and Adjusted Net Income

We use the terms Adjusted EBITDA and Adjusted Net Income throughout this Report. Adjusted EBITDA, as we define it, is a non-US GAAP measure. We define Adjusted EBITDA for the periods indicated as net income (loss), adjusted to exclude (i) depreciation and amortization, (ii) interest expense, net, (iii) income tax expenses (benefits), (iv) restructuring and impairment charges, (v) equity-based compensation expense, (vi) foreign currency loss (gain), net, (vii) derivative valuation loss (gain), net, (viii) secondary offering and others, (ix) loss on early extinguishment of senior notes and (x) restatement related expenses.

See the footnotes to the table below for further information regarding these items. We present Adjusted EBITDA as a supplemental measure of our performance because:

We use Adjusted EBITDA in a number of ways, including:

We encourage you to evaluate each adjustment and the reasons we consider them appropriate. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses similar to the adjustments in this presentation. Adjusted EBITDA is not a measure defined in accordance with US GAAP and should not be construed as an alternative to income from continuing operations, cash flows from operating activities or net income (loss), as determined in accordance with US GAAP. A reconciliation of net income (loss) to Adjusted EBITDA is as follows:

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

Because of these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our US GAAP results and using Adjusted EBITDA only supplementally.

We present Adjusted Net Income as a further supplemental measure of our performance. We prepare Adjusted Net Income by adjusting net income (loss) to eliminate the impact of a number of non-cash expenses and other items that may be either one time or recurring that we do not consider to be indicative of our core ongoing operating performance. We believe that Adjusted Net Income is particularly useful because it reflects the impact of our asset base and capital structure on our operating performance. We present Adjusted Net Income for a number of reasons, including:

Adjusted Net Income is not a measure defined in accordance with US GAAP and should not be construed as an alternative to income from continuing operations, cash flows from operating activities or net income (loss), as determined in accordance with US GAAP. We encourage you to evaluate each adjustment and the reasons we consider them appropriate. Other companies in our industry may calculate Adjusted Net Income differently than we do, limiting its usefulness as a comparative measure. In addition, in evaluating Adjusted Net Income, you should be aware that in the future we may incur expenses similar to the adjustments in this presentation. We define Adjusted Net Income for the periods indicated as net income (loss), adjusted to exclude (i) restructuring and impairment charges, (ii) equity-based compensation expense, (iii) amortization of intangibles, (iv) foreign currency loss (gain), net, (v) derivative valuation loss (gain), net, (vi) secondary offering and others, (vii) loss on early extinguishment of senior notes and (viii) restatement related expenses.

The following table summarizes the adjustments to net income (loss) that we make in order to calculate Adjusted Net Income (Loss) for the periods indicated:

In evaluating Adjusted EBITDA and Adjusted Net Income, you should be aware that in the future we may incur expenses similar to the adjustments in our presentation of Adjusted EBITDA and Adjusted Net Income. Our presentation of Adjusted EBITDA and Adjusted Net Income should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. Adjusted EBITDA and Adjusted Net Income are not measures defined in accordance with US GAAP and should not be construed as an alternative to operating income, cash flows from operating activities or net income (loss), as determined in accordance with US GAAP.

Our Adjusted EBITDA and Adjusted Net Loss for the year ended December 31, 2014 were $8.5 million and $38.1 million, respectively. Our Adjusted EBITDA and Adjusted Net Loss for the year ended December 31, 2013 were $20.0 million and $31.5 million, respectively. Our Adjusted EBITDA and Adjusted Net Income for the year ended December 31, 2012 were $124.3 million and $64.5 million, respectively.

Factors Affecting Our Results of Operations

Net Sales. We derive virtually all of our sales (net of sales returns and allowances) from three business lines: Display Solutions, Power Solutions and Semiconductor Manufacturing Services. Our product inventory is primarily located in Korea and is available for drop shipment globally. Outside of Korea, we maintain limited product inventory, and our sales representatives generally relay orders to our factories in Korea for fulfillment. We have strategically located our sales and technical support offices near concentrations of major customers. Our sales offices are located in Korea, the United States, Japan and Greater China. Our network of authorized agents and distributors consists of agents in the United States and Europe and distributors and agents in the Asia Pacific region. Our net sales from All other consist principally of the disposal of waste materials.

We recognize revenue when risk and reward of ownership pass to the customer either upon shipment, upon product delivery at the customer’s location or upon customer acceptance, depending on the terms of the arrangement. For the years ended December 31, 2014 and 2013, we sold products to over 282 and 284 customers, respectively, and our net sales to our ten largest customers represented 61% and 59% of our net sales, respectively. We have a combined production capacity of over 127,000 eight-inch equivalent semiconductor wafers per month. We believe our large-scale, cost-effective fabrication facilities enable us to rapidly adjust our production levels to meet shifts in demand by our end customers.

Gross Profit. Our overall gross profit generally fluctuates as a result of changes in overall sales volumes and in the average selling prices of our products and services. Other factors that influence our gross profit include changes in product mix, the introduction of new products and services and subsequent generations of existing products and services, shifts in the utilization of our manufacturing facilities and the yields achieved by our manufacturing operations, changes in material, labor and other manufacturing costs including outsourced manufacturing expenses, and variation in depreciation expense.

Average Selling Prices. Average selling prices for our products tend to be highest at the time of introduction of new products which utilize the latest technology and tend to decrease over time as such products mature in the market and are replaced by next generation products. We strive to offset the impact of declining selling prices for existing products through our product development activities and by introducing new products that command selling prices above the average selling price of our existing products. In addition, we seek to manage our inventories and manufacturing capacity so as to preclude losses from product and productive capacity obsolescence.

Material Costs. Our cost of material consists of costs of raw materials, such as silicon wafers, chemicals, gases and tape, packaging supplies, equipment maintenance and depreciation expenses. We use processes that require specialized raw materials, such as silicon wafers, that are generally available from a limited number of suppliers. If demand increases or supplies decrease, the costs of our raw materials could significantly increase.

Labor Costs. A significant portion of our employees are located in Korea. Under Korean labor laws, most employees and certain executive officers with one or more years of service are entitled to severance benefits upon the termination of their employment based on their length of service and rate of pay. As of December 31, 2014, approximately 98% of our employees were eligible for severance benefits.

Depreciation Expense. We periodically evaluate the carrying values of long-lived assets, including property, plant and equipment and intangible assets, as well as the related depreciation periods. We depreciated our property, plant and equipment using the straight-line method over the estimated useful lives of our assets. Depreciation rates vary from 30-40 years on buildings to 5 to 12 years for certain equipment and assets. Our evaluation of carrying values is based on various analyses including cash flow and profitability projections. If our projections indicate that future undiscounted cash flows are not sufficient to recover the carrying values of the related long-lived assets, the carrying value of the assets is impaired and will be reduced, with the reduction charged to expense so that the carrying value is equal to fair value.
