United Micro (UMC) Risk Factors

We are subject to U.S. disclosure rules on conflict minerals adopted by the SEC, pursuant to which we are required to conduct due diligence of our supply chain and file an annual report to disclose whether conflict minerals utilized by us originated in the Democratic Republic of the Congo (DRC) or an adjoining country. We have filed the conflict mineral disclosure report every year since 2014 in order to comply with such rules, we will continue to verify the relevant information with our vendors and suppliers and file the required report but we cannot assure you that we will be able to collect all the information required to comply with such regulations. If we are not able to confirm such information with vendors, or if we discover that some vendors are sourcing conflict minerals from prohibited countries, we may decide or be required to discontinue our relationship with such vendors, which may negatively impact our ability to obtain adequate supplies of materials needed for the manufacturing of our products and services. The failure to obtain necessary information or to maintain adequate supplies of materials from supply chains outside the DRC and adjoining countries may delay our production, increasing the risk of losing customers and business. Similarly, many jurisdictions have promulgated regulations with the intention to deter human rights violations within supply chains. Possible violation by our suppliers may not be known to us and is beyond our control. While we believe our suppliers comply with applicable human rights requirements, there can be no guarantee that they will continue to do so, or that we will be able to obtain the necessary information on their activities to comply with whatever future requirements may be enacted.

We are a company limited by shares incorporated under the R.O.C. Company Act. Most of our assets and most of our directors, executive officers and experts named in the registration statement are located in Taiwan. As a result, it may be difficult for you to enforce judgments obtained outside Taiwan upon us or such persons in Taiwan. We have been advised by our R.O.C. counsel that any judgment obtained against us in any court outside the R.O.C. arising out of or relating to the ADSs will not be enforced by R.O.C. courts if any of the following situations shall apply to such final judgment: - the court rendering the judgment does not have jurisdiction over the subject matter according to R.O.C. law;- the judgment or the court procedure resulting in the judgment is contrary to the public order or good morals of the R.O.C.;- the judgment was rendered by default, except where the summons or order necessary for the commencement of the action was legally served on us within the jurisdiction of the court rendering the judgment within a reasonable period of time or with judicial assistance of the R.O.C.; or - judgments of the R.O.C. courts are not recognized in the jurisdiction of the court rendering the judgment on a reciprocal basis.

We, like many R.O.C. technology companies, have benefited from substantial tax incentives provided by the R.O.C. government and other government authorities in countries and regions where we operate under various different tax incentive programs, which are subject to the review and approval by the relevant tax authorities on the case by case basis. Although we will make our best efforts to meet the requirements under different incentive schemes and make the relevant applications, we cannot assure you that the tax authorities will grant the approval as we apply. Our application may be denied for reasons outside of our control, including changes in tax incentive regulations and criteria for qualifications. Additionally, the tax incentives granted, taken as a whole, may not be as favorable to us as those currently in effect.  If any of the above occurs, our net income may decrease.

Governments in the United States, PRC and certain other countries have implemented fiscal and monetary programs to stimulate economic growth as a result of the recent economic downturn, and many of these programs include protectionist measures that encourage the use of domestic products and labor. Recent policy developments by the governments in US, China and elsewhere also suggest an increased unwillingness to allow international companies to invest in or acquire local businesses. Since many of our direct customers and other downstream customers in the supply chain are located in or have operations in the countries where protectionist measures were adopted, such protectionist measures may have a material adverse effect on demand for our manufacturing services.

Geopolitical conflicts and tensions between the United States and China have threatened and destabilized trading relationships and economic activities between the two countries. Because we have operations in both countries, such conflicts and tensions may negatively impact our business. At various times during recent years, the United States and China have had disagreements over political and economic issues, including but not limited to, the recent imposition of tariffs by the U.S. on goods imported from China and to the U.S. government's efforts to restrict transfer and sharing of technologies, including semiconductor technologies, between the two countries. In addition, the U.S. government may enact new and more restrictive export control regulations that may reduce our ability to ship and sell products to certain customers in China and Asia and increase our cost to implement additional measures to comply with such new regulations. In addition, disagreements between the United States and China with respect to their political, military or economic policies toward Taiwan may contribute to further controversies. These controversies and trade frictions could have a material adverse effect on our business by, among other things, making it more difficult for us to coordinate our operations between the United States and China, causing a reduction in the demand for our products by customers in the United States or China and reducing our profitability due to increasing cost of compliance.

There is increasing concern that climate change is occurring and may have dramatic effects on human activity without aggressive remediation steps. A modest change in temperature would result in increased coastal flooding, changing precipitation patterns and increasing risk of extinction for the world's species. Public expectations for reductions in greenhouse gas emissions could result in increased energy, transportation and raw material costs, which raised stakeholder's concern and caused several international standards and questionnaires being revised to request enterprises disclosing their climate-related risks and financial impacts. Consequently, our climate change risk assessment tool was developed and related departments participated in the identification work. Adaptation and mitigation measures are developed in response to the identified climate change risk. We have a state-of-the-art 12-inch wafer fab in Singapore. The Singapore government introduced a carbon tax from 2019 onwards, making it the first country in Southeast Asia to promote this measure. In Taiwan, there is a plan to modify the Greenhouse Gas Reduction and Management Act that the collection of carbon tax/carbon fee may also be implemented in Taiwan; however, the current policy is not yet clear. There are additional regulations under the Greenhouse Gas Reduction and Management Act and a revised Renewable Energy Development Act that imposes fines for greenhouse gas GHG emissions exceeding the total controlled amount, and either mandatory green electricity certification purchase or payment for inadequate proportion of green electricity use. We have transformed the carbon emissions into potential carbon costs based on the analysis of the carbon risk scenarios of each fab, and have actively carried out a phased greenhouse gas reduction plan. The measures for the use of clean energy include the reduction of raw materials, setting of high-efficiency greenhouse gas breakdown equipment, etc., and building solar energy systems. We take an aggressive stance in reducing the impact of carbon emissions and taxes, enhancing its operational competitive advantage. As electricity use increases across Taiwan Science Parks, the local government has continued to encourage companies to utilize renewable energy resources. Government authorities have enacted regulations requiring Taiwan R.O.C. companies with significant energy consumption requirements, such as UMC, to derive 10% of the capacity under contract from renewable energy by 2025, but companies that make commitment to achieve renewable energy goals earlier are permitted to comply with a lower threshold of requirement. UMC plans to achieve required commitment in contracted renewable energy capacity requirements by 2023, two years before the 2025 mandate, therefore UMC will be required to derive 8% of its capacity under contract from renewable energy resources under such regulations. To fulfill this mandate, companies including UMC must develop and implement renewable energy solutions such as installing solar-powered resources or outsourcing from renewable energy vendors. As a result, we anticipate in the next few years that the adoption of higher renewable power resources will result in an increase in purchases of renewable energy consumption, which will impact UMC's financial conditions and results of operations. If the we experience unforeseen interruptions in renewable generators (or back up power generators) or issues arising from renewable energy, especially during peak power consumption periods, the power supply for our manufacturing facility may be disrupted, which could adversely affect our business operation, financial conditions and results of operations.

More than half of our operating revenues are denominated in currencies other than New Taiwan dollars, primarily in U.S. dollars. On the other hand, more than half of our costs of direct labor, raw materials and overhead are incurred in New Taiwan dollars. Although historically we hedged a portion of the resulting net foreign exchange position through the use of foreign exchange spot transactions, or currency forward contracts, we are still affected by fluctuations in foreign exchange rates among the U.S. dollar, the New Taiwan dollar and other currencies. Any significant fluctuation in exchange rates may impact on our financial condition and the U.S. dollar value of the ADSs and the U.S. dollar value of any cash dividends we distributed, which could have an adverse effect on the market price of the ADSs.

We use highly flammable materials such as silane and hydrogen in our manufacturing processes and may therefore be subject to the risk of loss arising from fires. The risk of fire associated with these materials cannot be completely eliminated. We maintain insurance policies to reduce losses caused by fire, including business interruption insurance. However, our insurance coverage is subject to deductibles and self-insured retention and may not be sufficient to cover all of our potential losses. If any of our fabs were to be damaged or cease operations as a result of a fire, it would temporarily reduce manufacturing capacity and reduce revenues.

The success of our business depends upon attracting and retaining experienced executives, engineers and other employees to implement our strategy. The competition for skilled employees is intense. We expect demand for personnel in Taiwan to increase in the future as new wafer fabrication facilities and other businesses are established in Taiwan. We also expect demand for experienced personnel in other locations to increase significantly as our competitors establish and expand their operations. Some of our competitors are willing to offer better compensation than what we do to our executives, engineers and other employees. We do not have long-term employment contracts with any of our employees. If we were unable to retain our existing personnel or attract, assimilate and recruit new experienced personnel in the future, it could seriously disrupt our operations and delay or restrict the growth of our business.

The worldwide semiconductor foundry industry is highly competitive. We compete with dedicated foundry service providers such as Taiwan Semiconductor Manufacturing Company Limited, Semiconductor Manufacturing International (Shanghai) Corporation, Globalfoundries Inc., as well as the foundry operation services of some integrated device manufacturers, such as Intel, Samsung Electronics, or Samsung, SK Hynix and Toshiba Corporation, or Toshiba. Integrated device manufacturers principally manufacture and sell their own proprietary semiconductor products, but may also offer foundry services. Other competitors such as Dongbu Anam Semiconductor, , Huahong, Powerchip, TowerJazz, Vanguard and XMC have initiated efforts to expand and develop substantial additional foundry capacity. New entrants and consolidations in the foundry business are likely to initiate a trend of competitive pricing and create potential overcapacity in legacy technology. Some of our competitors have greater access to capital and substantially greater production, research and development, marketing and other resources than we do. As a result, these companies may be able to compete more aggressively over a longer period of time than we can. The principal elements of competition in the wafer foundry market include: - technical competence;- time-to-volume production and cycle time;- time-to-market;- research and development quality;- available capacity;- manufacturing yields;- customer service and design support;- price;- management expertise; and - strategic alliances. Our ability to compete successfully also depends on factors partially outside of our control, including product availability, IP, including cell libraries that our customers embed in their product designs, and industry and general economic trends.

Our customers generally use the semiconductors produced in our fabs in a wide variety of applications. We derive a significant percentage of our operating revenues from customers who use our manufacturing services to make semiconductors for communication devices, consumer electronics, PCs and other computers. The semiconductor industry experienced several downturns due to recent major financial crises and natural disasters. These downturns resulted in a reduced demand for our services and hence decreased our revenues and earnings. Any significant decrease in the demand for communication devices, consumer electronics, PCs or other computers may further decrease the demand for our services. In addition, if the average selling price of communication devices, consumer electronics, PCs or other computers decline significantly, we will be pressured to further reduce our selling prices, which may reduce our revenues and, therefore, reduce our margins significantly. As demonstrated by downturns in demand for high technology products in the past, market conditions can change rapidly, without apparent warning or advance notice. In such instances, our customers will experience inventory buildup and/or difficulties in selling their products and, in turn, will reduce or cancel orders for wafers from us. The timing, severity and recovery of these downturns cannot be predicted accurately or at all. When they occur, our business, profitability and price of the common shares and ADSs are likely to suffer. In addition, we may not be able to verify or guarantee the creditworthiness of some of our customers. If customers fail to make payments on a timely basis and accumulate substantial accounts receivable, we may not be able to collect payments or may incur substantial costs and expenses to pursue legal remedies to recover such losses, which may have an adverse effect on our financial conditions and results of operations.

The semiconductor industry is developing rapidly and the related technology is constantly evolving. If we do not anticipate the technology evolution and rapidly adopt new and innovative technology, we may not be able to produce sufficiently advanced services at competitive prices. There is a risk that our competitors may adopt new technology before we do, resulting in our loss of market share. If we are unable to begin offering advanced services and processes on a competitive and timely basis, we may lose customers to our competitors providing similar technologies, which may cause our operating revenues to decline unless we can replace lost customers with new customers. In addition, the market prices for advanced technology and services tend to fall over time. As a result, if we are unable to offer new advanced services and processes on a competitive and timely basis, we may need to reduce prices that we set for our existing services and processes, which would have a negative effect on our profitability. We also depend upon the introduction of new technologies on a timely basis in order to benefit from the relatively higher prices such new technologies offer in the earlier stages of their life cycles. If we are unable to introduce new technologies on a timely and competitive basis, we may not be able to benefit from the relatively higher prices for new technologies, and our average selling price and profits would decrease accordingly.
