Advanced Energy (AEIS) Risk Analysis

Our success depends to a significant degree upon the continuing contributions of our management, technical, marketing, and sales employees. If we are unable to attract, retain, and motivate qualified employees and leaders as required, we may be unable to fully capitalize on current and new market opportunities, which could adversely impact our business and results of operations. Our success in hiring and retaining employees depends on a variety of factors, including market competitive compensation and benefits programs, global economic or political and industry conditions, our organizational structure, our reputation, culture and working environment, competition for talent and the availability of qualified employees, the readiness for and availability of career development opportunities, and our ability to offer a challenging, safe, and rewarding work environment. We have experienced, and may continue to experience, increasing costs to attract and retain qualified talent, driven by macroeconomic conditions and a highly competitive labor market. In addition, the loss or retirement of key employees presents challenges to the extent the departing employee had valuable institutional knowledge or experience. This requires us to identify and train existing or new employees to perform necessary functions, therefore causing unforeseen delays, which could result in unexpected costs, reduced productivity, or an impact to internal processes and controls. If we fail to have succession plans in place for key roles, we may not be able to maintain continuity and our business could be adversely affected.

Requirements applicable to our supply chain include rules aimed at promoting transparency as well as rules that restrict sourcing from certain locations or suppliers. For example, rules aimed at extinguishing forced labor require extensive efforts to map supply chains effectively and efficiently beyond tier 1 suppliers for any involvement in human rights abuses. Goods suspected of being manufactured with forced labor could be blocked from importation into the U.S., which could impact revenue. Another possible risk is U.S. or foreign governments that restrict our access to supply; for example, China has restricted exports of rare earth minerals, and the U.S. government's export controls have resulted in restricted supply chains. Given such restrictions, we may be unable to obtain supply in a timely manner, in sufficient quantities, or at a commercially reasonable cost.

The markets we serve are constantly changing in terms of advancement in applications, core technology, and competitive pressures driven by continuing technology migration and changing customer demand. New products designed for capital equipment manufacturers typically have a lifespan of many years. Increasingly, we are required to accelerate our investment in research and development to meet the time-to-market, performance, and technology adoption cycle needs of our customers simply to compete for design wins. Given such up-front investments we make to develop, evaluate, and qualify products in the design win process, our success and future growth depend on our products being designed into our customers' new generations of equipment as they develop new technologies and applications. We must work with these manufacturers early in their design cycles to modify, enhance, and upgrade our products or design new products that meet the requirements of their new systems. The design win process is highly competitive, the design windows may be narrow, and there is no assurance we will succeed with new design wins for our existing customers or new customers' next generations of equipment. Our competitors may also be more successful in implementing an AI strategy and develop more successful products with the aid of AI technology. In the last few years, we have made significant investments to launch new technology platforms and products into the Semiconductor and Industrial and Medical markets and upgrade our capabilities in the Data Center Computing market. If existing or new customers do not choose our designs, we are unable to maintain single source status, or we cannot agree to pricing, volumes, and other key commercial terms with these customers, our market share may decline, potential revenues related to the lifespan of our products may not be realized, and our business, financial condition, and results of operations could be materially and adversely impacted. Further, our ability to generate revenue or gross profit from design wins is in part or wholly dependent upon the success of our customers' solutions.

Our success depends significantly on our proprietary technology. We attempt to protect our intellectual property rights through a variety of methods including trade secrets, patents, and non-disclosure agreements; however, we might not be able to protect our technology, and customers or competitors might be able to develop similar technology. Infringement, misappropriation, and unlawful use of our intellectual property rights, and resulting unauthorized manufacture or sale of equipment using our IP rights, or loss of IP from employee turnover, could result in lost revenue. Monitoring and detecting any unauthorized use of intellectual property is difficult and costly and we cannot be certain that the protective measures we have implemented will completely prevent theft or misuse. If we are unable to protect our intellectual property successfully, our business, financial condition, and results of operations could be materially and adversely affected. Patents, trademarks, and trade secret protection may not be adequate to deter infringement or misappropriation of our proprietary rights. For example, patents issued to us may be challenged, invalidated, or circumvented. The loss or expiration of any of our key patents could lead to a significant loss of sales of certain of our products and could materially affect our future operating results. The process of seeking patent protection can be time consuming and expensive and patents may not be issued for currently pending or future applications. Moreover, our existing patents or any new patents that may be issued may not be sufficient in scope or strength to provide meaningful protection or any commercial advantage to us. We may initiate claims, enforcement actions or litigation against third parties for infringement of our proprietary rights, which claims could result in costly litigation, the diversion of our technical and management personnel, and the assertion of counterclaims by defendants. In addition, the laws of some foreign countries might not afford our intellectual property the same protections as do the laws of the United States. Our intellectual property is not protected by patents in several countries in which we do business, and we have limited or no patent protection in other countries, including China. Consequently, manufacturing our products in these countries may subject us to an increased risk that unauthorized parties may attempt to copy our products or otherwise obtain or use our intellectual property. Third parties may also assert claims against us and our products or business practices. Claims that our products or business practices infringe the rights of others, whether or not meritorious, can be expensive and time-consuming to defend and resolve, and may divert the efforts and attention of management and personnel. The inability to obtain rights to use third party intellectual property on commercially reasonable terms could also have an adverse impact on our business. In addition, we may face claims based on the theft or unauthorized use or disclosure of third party trade secrets and other confidential business information. Any such incidents and claims could severely harm our business and reputation, result in significant expenses, harm our competitive position, and prevent us from selling certain products, all of which could have a material and adverse impact on our business and results of operations.

As part of our day-to-day business, we process, transmit and store our own confidential data and certain data about our customers and employees in our global information technology system. We are subject to ongoing data security threats, including phishing attempts, denial of service attacks, ransomware, viruses, and other malware, employee error or malfeasance, theft, natural disasters, and hardware or software malfunctions, any one of which could compromise our data security, cause the loss of critical data, or disrupt operations, which could materially adversely affect our business and results of operations. Additionally, third parties may attempt to fraudulently induce employees or customers into disclosing sensitive information such as usernames, passwords, or other information to gain access to our customers' data or our data or our information technology systems. We and our third party providers have experienced, and expect to continue to experience, cybersecurity events from external actors and confidential information theft from internal actors, some of which could be devastating. We continue to devote significant resources to cybersecurity, IP protection, data encryption, and other measures to protect our systems and data from unauthorized external access or internal misuse, and we may be required to expend greater resources in the future for cybersecurity protection, compliance, and remediation, especially in the face of continuously evolving and increasingly sophisticated cybersecurity threats and privacy and data protection laws. Despite our implementation of cybersecurity measures, there is no assurance that our actions will be sufficient to prevent future threats and incidents. Because the techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. A cybersecurity event or other breach, disruption, or failure of our information and operational systems, could: - result in the disclosure, misuse, corruption, or loss of our confidential business information, intellectual property including trade secrets, or our customers' data;- damage our reputation;- lead to a loss of confidence by our current and potential customers;- adversely impact our future revenue;- disrupt our business;- divert management attention; and - expose us to significant remediation costs, legal liability, and litigation risk.

Our business could be adversely affected to the extent we fail to appropriately manage, expand, and update our information technology infrastructure. In particular, we are in the process of implementing a global enterprise resource planning ("ERP") system and other enterprise-wide applications that will upgrade and standardize our information systems. These implementations are expected to occur in phases over the next several years. In 2025, we shifted our deployment strategy for the new ERP system to a more staggered approach and delayed widespread implementation to better align with our business needs and risk tolerance. Delays, unexpected challenges, or a failure to achieve our implementation goals may lead to cost overrun, diversion of management attention and resources, or otherwise adversely impact our operations. In addition, the failure to anticipate the necessary readiness and training needs, manage the transition to systems, or appropriately convert historical and concurrent data could lead to business disruption and potential loss of business. Failure or abandonment of any part of the ERP system could result in a write-off of part or all of the costs that have been capitalized on the project.

We are a global organization. We have employees in the Asia-Pacific region, Europe, and North America. Our manufacturing facilities are located across the globe (mainly in the Asia-Pacific region), and revenue from customers outside the United States represented 70% of our total revenue during the year ended December 31, 2025. Given the global nature of our business, we have both domestic and international concentrations of cash and investments. The value of our cash, cash equivalents, and marketable securities can be adversely affected by liquidity, credit deterioration, inflation, foreign currency exchange rate fluctuations, financial results, economic risk, political risk, sovereign risk, or other factors. Additionally, our success producing goods internationally and competing in international markets is subject to our ability to manage various operational risks and difficulties, including, but not limited to: - our ability to effectively hire, manage, and retain our employees at locations operating in different business environments from the United States;- our ability to develop and maintain relationships with suppliers and other local businesses;- interruptions to our and/or our suppliers' supply chain;- global trade issues and changes in and uncertainties with respect to trade and export regulations, trade policies and sanctions, tariffs, and international trade disputes, including export regulations for certain exports to China and any retaliatory measures;- compliance with product safety requirements and standards that are different from those of the United States;- variations and changes in laws applicable to our operations in different jurisdictions, including enforceability of contract rights;- ineffective or inadequate legal and physical protection of intellectual property rights in certain countries;- delays or restrictions on personnel travel and in shipping materials or finished products between and within countries;- political instability, international hostilities, natural disasters, health epidemics, disruptions in financial markets, and deterioration of economic conditions;- our ability to maintain appropriate business processes, procedures, and internal controls, and comply with environmental, health and safety, anti-corruption, and other regulatory requirements;- customs regulations including customs audits in various countries that occur from time to time;- the ability to provide enough levels of technical support in different locations;- our ability to obtain business licenses that may be needed in international locations to support expanded operations;- changes in tariffs, income tax, value added tax, and foreign currency exchange rates; and - laws and regulations regarding privacy, data use and processing, data privacy and protection, cybersecurity, and network security.

Currency exchange rate fluctuations could have an adverse effect on our revenue and results of operations, and we could experience losses with respect to forward exchange contracts into which we may enter. Unfavorable currency fluctuations could significantly increase the labor and other costs incurred in the operation of our international facilities and the cost of raw materials, parts, components, and subassemblies that we source there, which could materially and adversely affect our results of operations. These increased costs could require us to increase prices to foreign customers, which could result in lower net revenue from such customers. Alternatively, if we do not adjust the prices for our products in response to unfavorable currency fluctuations, our results of operations could be materially and adversely affected. In addition, we have large, long-term liabilities, such as local lease and pension liabilities in Asia and Europe creating more significant exposure to fluctuations in numerous currencies. We do not attempt to hedge these exposures given the long-term nature of the underlying liabilities and the non-cash nature of the foreign exchange gain or loss.

As a supplier to the global semiconductor equipment, data center computing, industrial, medical, telecommunication, and networking industries, we are subject to business fluctuations, the timing, length, and volatility of which can be difficult to predict. We are impacted by sudden changes in customers' manufacturing capacity requirements and spending, which depend in part on technology transitions, capacity utilization, demand for customers' products, inventory levels relative to demand, access to affordable capital, and changes in geopolitical factors, including tariffs. These changes have affected the timing and amount of customers' purchases and investments in technology, and continue to affect our orders, net revenue, operating expenses, and net income. In addition, several of the markets in which we compete are highly cyclical and experience downturns characterized by diminished product demand, production overcapacity, high inventory levels, and price erosion, which has caused, and in the future could cause, our revenue and gross margin to decline, adversely impacting our results of operations. It is difficult to predict the timing, length, and severity of such fluctuations and downturns, and we may not be able to respond adequately or quickly to the changes in demand. To meet rapidly changing demand in each of the industries we serve, we must effectively manage our resources and production capacity. During periods of decreasing demand for our products, we must be able to appropriately align our cost structure with prevailing market conditions, effectively manage our supply chain, and motivate and retain key employees. During periods of increasing demand, we must have enough manufacturing capacity and inventory to fulfill customer orders, effectively manage our supply chain, and attract, retain, and motivate enough qualified individuals. If we are not able to timely and appropriately adapt to changes in our business environment or to accurately assess where we are positioned within a business cycle, our business, financial condition, or results of operations may be materially and adversely affected. For example, infrastructure investments in artificial intelligence ("AI") have increased substantially, which is driving significant demand increases in the Data Center Computing market. We accelerated investments to increase capacity and make upgrades to support higher demand and new product requirements in the market, but if we are unable to timely or efficiently scale to meet growing demand or if we have not accurately assessed the magnitude or sustainability of such demand, our results of operations could be adversely impacted.
