Risk factors and legal proceedings

The risks Diodes Incorporated names in Item 1A of its 10-K filed Feb 10, 2026: 57 risks under these headings, as written.16

  • RISKS RELATED TO OUR BUSINESS
  • The impact of tariffs assessed or contemplated to be assessed by various governments could have a material adverse effect on our business, financial condition, and results of operations.
  • The impact of pandemics may have a material adverse effect on our business, financial condition, and results of operations.
  • During times of difficult market conditions, our fixed costs combined with lower net sales and lower profit margins may have a negative impact on our business, operating results, and financial condition.
  • Downturns in the highly cyclical semiconductor industry or changes in end-market demand could adversely affect our operating results and financial condition.
  • The semiconductor business is highly competitive, and increased competition may harm our business, operating results, and financial condition.
  • Delays in initiation of production at facilities due to implementing new production techniques or resolving problems associated with technical equipment malfunctions could adversely affect our manufacturing efficiencies, operating results, and financial condition.
  • We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth and profit margins.
  • Our customers may require our products to undergo a lengthy and expensive qualification process without any assurance of product sales and may audit our operations from time to time. A failure to qualify a product or a negative audit finding could adversely affect our net sales, operating results, and financial condition.
  • Our customer orders are subject to cancellation or modification usually with no penalty. High volumes of order cancellation or reduction in quantities ordered could adversely affect our net sales, operating results, and financial condition.
  • Production at our manufacturing facilities could be disrupted for a variety of reasons, including natural disasters and other extraordinary events, which could prevent us from producing enough of our products to maintain our sales and satisfy our customers’ demands and could adversely affect our operating results and financial condition.
  • New technologies could result in the development of new products by our competitors and a decrease in demand for our products, and we may not be able to develop new products to satisfy changes in demand, which would adversely affect our net sales, market share, operating results, and financial condition.
The other 46 risks
  • We may be subject to claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result in significant expense, reduction in our intellectual property rights and a negative impact on our business, operating results, and financial condition.
  • We depend on third-party suppliers for timely deliveries of raw materials, manufacturing services, product and process development, parts, and equipment, as well as finished products from other manufacturers, and our reputation with customers, operating results, and financial condition could be adversely affected if we are unable to obtain adequate supplies in a timely manner.
  • A significant part of our growth strategy involves acquiring companies and businesses. We may be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we may be unable to successfully integrate any acquired companies with our operations, which could adversely affect our business, operating results, and financial condition.
  • We are subject to many environmental laws and regulations that could result in significant expenses and could adversely affect our business, operating results, and financial condition.
  • We may incur additional costs and face emerging risks associated with environmental, social and governance (“ESG”) factors impacting our operations.
  • Our products, or products we purchase from third parties for resale, may be found to be defective and, as a result, warranty claims and product liability claims may be asserted against us and we may not have recourse against our suppliers, which may harm our business, reputation with our customers, operating results, and financial condition.
  • We may fail to attract or retain the qualified technical, sales, marketing, finance, and management/executive personnel required to operate our business successfully, which could adversely affect our business, operating results, and financial condition.
  • We may not be able to achieve future growth, and any such growth may place a strain on our management and on our systems and resources, which could adversely affect our business, operating results, and financial condition.
  • Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely affect our business, operating results, and financial condition.
  • If our direct sales customers or our distributors’ customers do not design our products into their applications, our net sales may be adversely affected.
  • We are subject to interest rate risk that could have an adverse effect on our cost of working capital and interest expenses, which could adversely affect our business, operating results, and financial condition.
  • Our hedging strategies may not be successful in mitigating our risks associated with interest rates or foreign exchange exposure or our counterparties might not perform as agreed.
  • We may have a significant amount of debt with various financial institutions worldwide. Any indebtedness could adversely affect our business, operating results, financial condition, and our ability to meet payment obligations under such debt.
  • Restrictions in our credit facilities may limit our business and financial activities, including our ability to obtain additional capital in the future.
  • Our business benefits from certain Chinese government incentives. Expiration of, or changes to, these incentives could adversely affect our operating results and financial condition.
  • We operate a global business through numerous foreign subsidiaries, and there is a risk that tax authorities will challenge our transfer pricing methodologies or legal entity structures, which could adversely affect our operating results and financial condition.
  • Certain of our employees in the U.K. participate in a company-sponsored defined benefit plan which subjects the Company to risks associated with the estimates and assumptions used in calculating expense and funding requirements recorded in the Company’s consolidated financial statements. Inaccuracies or changes in these estimates could require material changes in the expense and funding required.
  • Compliance with government regulations and customer demands regarding the use of “conflict minerals” may result in increased costs and may have a negative impact on our business, operating results, and financial condition.
  • If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal control over financial reporting, we may not be able to report our financial results accurately or detect fraud, which could harm our business and the trading price of our Common Stock.
  • RISKS RELATED TO OUR INTERNATIONAL OPERATIONS
  • Our international operations subject us to risks that could adversely affect our operations.
  • A slowdown in the Chinese economy could limit the growth in demand for electronic devices containing our products, which would have a material adverse effect on our business, operating results, and prospects.
  • Economic regulation in China could materially and adversely affect our business, operating results, and prospects.
  • We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act, the U.K.’s Bribery Act 2010, China’s anti-corruption campaign and similar worldwide anti-bribery laws.
  • We are subject to foreign currency risk as a result of our international operations.
  • China is experiencing rapid social, political and economic change, which has increased labor costs and other related costs that could make doing business in China less advantageous than in prior years. Increased labor costs in China could adversely affect our business, operating results, and financial condition.
  • We may not continue to receive preferential tax treatment in Asia, thereby increasing our income tax expense and reducing our net income.
  • The distribution of any earnings of certain foreign subsidiaries may be subject to foreign income taxes, thus reducing our net income.
  • We could be adversely affected by the compromise or theft of our technology, know-how, data, or intellectual property or a requirement that we yield rights in technology, know-how, data stored in foreign jurisdictions, or intellectual property that we use in such foreign jurisdictions.
  • RISKS RELATED TO OUR COMMON STOCK
  • Variations in our quarterly operating results may cause our stock price to be volatile.
  • We may enter into future acquisitions and take certain actions in connection with such acquisitions that could adversely affect the price of our Common Stock.
  • Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation and Bylaws, may hinder a take-over attempt.
  • GENERAL RISK FACTORS
  • The continued hostilities between Ukraine and Russia could negatively impact our business.
  • The success of our business depends on the strength of the global economy and the stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our net sales, operating results, and financial condition.
  • We may be adversely affected by any disruption in our information technology systems, which could adversely affect our cash flows, operating results, and financial condition.
  • Terrorist attacks, or threats or occurrences of other terrorist activities, whether in the U.S. or internationally, may affect the markets in which our Common Stock trades, the markets in which we operate and our operating results and financial condition.
  • System security risks, data protection breaches, cyber-attacks and other related cybersecurity issues could disrupt our internal operations, and any such disruption could reduce our expected net sales, increase our expenses, damage our reputation, and adversely affect our stock price.
  • Our customers may require our products to undergo a lengthy and expensive qualification process without any assurance of product sales and may audit our operations from time to time. A failure to qualify a product or a negative audit finding could adversely affect our net sales, operating results and financial condition.
  • We may be subject to claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result in significant expense, reduction in our intellectual property rights, and a negative impact on our business, operating results, and financial condition.
  • We may incur additional costs and face emerging risks associated with environmental, social, and governance (“ESG”) factors impacting our operations.
  • We may fail to attract or retain the qualified technical, sales, marketing, finance and management/executive personnel required to operate our business successfully, which could adversely affect our business, operating results, and financial condition.
  • Certain of our employees in the U.K. participate in a company-sponsored defined benefit plan (the “Plan”), which subjects the Company to risks associated with the estimates and assumptions used in calculating expense and funding requirements recorded in the Company’s consolidated financial statements. Inaccuracies or changes in these estimates could require material changes in the expense and funding required.
  • We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act, the U.K.’s Bribery Act 2010, China’s anti-corruption campaign, and similar worldwide anti-bribery laws.
  • China is experiencing rapid social, political, and economic change, which has increased labor costs and other related costs that could make doing business in China less advantageous than in prior years. Increased labor costs in China could adversely affect our business, operating results, and financial condition.
  • Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation, may hinder a take-over attempt.
  • Terrorist attacks, or threats or occurrences of other terrorist activities, whether in the U.S. or internationally, may affect the markets in which our Common Stock trades, the markets in which we operate, and our operating results and financial condition.
  • System security risks, data protection breaches, cyber-attacks, and other related cybersecurity issues could disrupt our internal operations, and any such disruption could reduce our expected net sales, increase our expenses, damage our reputation, and adversely affect our stock price.

Legal proceedings

From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any current pending legal proceeding will not have any material adverse effect on our financial position, cash flows, or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods. In addition, our foreign operations expose us to unique intellectual property technology risks compared to a company with fewer or no international operations. Such risks could lead to litigation or other disputes that would not be applicable to a company with limited or no international operations and could have a material and adverse effect on our financial condition and results of operations. See “Risk Factors – Risks Related to Our International Operations.” in Part I, Item 1A of this Annual Report for a more detailed summary of the intellectual property technology risks associated with our international business operations.
