Rapid technological changes in semiconductor manufacturing processes subject us to increased pressure to develop technological advances that enable those processes. We believe that our future success depends in part upon our ability to develop and offer new products with improved capabilities and to continue to enhance our existing products. If new products or existing products have reliability, quality, design, or safety problems, our performance may be impacted by reduced orders, higher manufacturing costs, delays in acceptance of and payment for new products, and additional service and warranty expenses. We may be unable to develop and manufacture products successfully, or products that we introduce may fail in the marketplace. For more than 25 years, the primary driver of technology advancement in the semiconductor industry has been to shrink the lithography that prints the circuit design on semiconductor chips. That driver could be approaching its technological limit, leading semiconductor manufacturers to investigate more complex changes in multiple technologies in an effort to continue technology development. In addition, the emergence of “big data” and new tools such as machine learning and artificial intelligence (“AI”) that capitalize on the availability of large data sets is leading semiconductor manufacturers and equipment manufacturers to pursue new products and approaches that exploit those tools to advance technology development. In the face of uncertainty on which technology solutions will become successful, we will need to focus our efforts on developing the technology changes that are ultimately successful in supporting our customers’ requirements. Our failure to develop and offer the correct technology solutions in a timely manner with productive and cost-effective products could adversely affect our business in a material way. Our failure to commercialize new products in a timely manner could result in loss of market share, unanticipated costs, and inventory obsolescence, which would adversely affect our financial results.

In order to develop new products and processes and enhance existing products and processes, we expect to continue to make significant investments in R&D, to investigate the acquisition of products and technologies, to invest in or acquire businesses or technologies, and to pursue joint development relationships with customers, suppliers, or other members of the industry. Our investments and acquisitions may not be as successful as we may expect, particularly in the event that we invest in or acquire product lines and technologies that are new to us. We may find that acquisitions are not available to us, for regulatory or other reasons, and that we must therefore limit ourselves to collaboration and joint venture development activities that do not have the same benefits as acquisitions. Pursuing development through collaboration and/or joint development activities rather than through an acquisition may pose substantial challenges for management, including those related to aligning business objectives; sharing confidential information, intellectual property and data; sharing value with third parties; and realizing synergies that might have been available in an acquisition but are not available through a joint development project. We must manage product transitions and joint development relationships successfully, as the introduction of new products could adversely affect our sales of existing products and certain jointly developed technologies may be subject to restrictions on our ability to share that technology, which could limit our market for products incorporating those technologies. Future technologies, processes, or product developments may render our current product offerings obsolete, leaving us with non-competitive products, obsolete inventory, or both. Moreover, customers may adopt new technologies or processes to address the complex challenges associated with next-generation devices. This shift may result in a reduction in the size of our addressable markets or could increase the relative size of markets in which we either do not compete or have relatively low market share.

Moreover, customers may adopt new technologies or processes to address the complex challenges associated with next-generation devices, or may adopt new technologies, including those based upon AI, that reduce their reliance on us for process development. This shift could reduce the size of our addressable markets, increase the relative size of markets in which we either do not compete or have relatively low market share, or reduce our competitiveness within the markets in which we do compete.

Previous wording

We face significant competition from multiple competitors, and our competitors may be able to develop products comparable or superior to those we offer or may adapt more quickly to new technologies or evolving customer requirements. In particular, while we continue to develop product enhancements that we believe will address future customer requirements, we may fail in a timely manner to identify those future customer requirements, to devote appropriate resources to developing products to address those requirements, or to complete the development or introduction of these additional product enhancements successfully, or these product enhancements may not achieve market acceptance or be competitive. Accordingly, competition may intensify, and we may be unable to continue to compete successfully in our markets, which could have a material adverse effect on our revenues, operating results, financial condition, and/or cash flows.

Previous wording

With increased consolidation efforts in our industry, as well as the emergence and strengthening of new, regional competitors, we may face increasing competitive pressures. Other companies continue to develop systems and/or acquire businesses and products that are competitive to ours and may introduce new products and product capabilities that may affect our ability to sell and support our existing products. We face a greater risk if our competitors enter into strategic relationships with leading semiconductor manufacturers covering products similar to those we sell or may develop, as this could adversely affect our ability to sell products to those manufacturers.

Other companies continue to develop systems and/or acquire businesses and products that are competitive to ours and may introduce new products and product capabilities that may affect our ability to sell and support our existing or new products. We face a greater risk if our competitors enter into strategic relationships with leading semiconductor manufacturers covering products addressing applications similar to those we sell or may develop products for, as this could adversely affect our ability to sell products to those manufacturers for those applications. We also face greater risk if our competitors acquire, or otherwise obtain control over, third parties that supply us with key intellectual property, technology, materials, components, software, or other inputs critical to our products and processes, as this could limit or condition our access to these inputs, result in the termination or non‑renewal of licenses or supply arrangements, restrict our ability to use or develop certain technologies, or otherwise disadvantage us relative to our competitors, which could adversely affect our product development, processes, and competitive position.

Previous wording

We believe that to remain competitive we must devote significant financial resources to offer products that meet our customers’ needs, to maintain customer service and support centers worldwide, and to invest in product and process R&D. Technological changes and developing technologies have required, and are expected to continue to require, new and costly investments. Certain of our competitors, including those that are created and financially backed by foreign governments, have substantially greater financial resources and more extensive engineering, manufacturing, marketing, and customer service and support resources than we do and therefore have the potential to offer customers a more comprehensive array of products and/or product capabilities and to therefore achieve additional relative success in the semiconductor equipment industry. These competitors may deeply discount or give away products similar to those that we sell, challenging or even exceeding our ability to make similar accommodations and threatening our ability to sell those products. We also face competition from our own customers, who in some instances have established affiliated entities that manufacture equipment similar to ours. In addition, we face competition from companies that exist in a more favorable legal or regulatory environment than we do, who are able to sell products for certain applications at certain customers that we are prohibited from selling to under applicable export controls, allowing the freedom of action in ways that we may be unable to match and potentially contributing to the strengthening of such companies’ ability to compete with us. In many cases, speed to solution is necessary for customer satisfaction and our competitors may be better positioned to achieve these objectives. For these reasons, we may fail to continue to compete successfully worldwide.

The semiconductor capital equipment industry has historically been characterized by rapid changes in demand. Variability in our customers’ business plans may lead to changes in demand for our equipment and services, which could negatively impact our results. The variability in our customers’ investments during any particular period is dependent on several factors, including, but not limited to, electronics demand, economic conditions (both general and in the semiconductor and electronics industries), industry supply and demand, prices for semiconductors, and our customers’ ability to develop and manufacture increasingly complex and costly semiconductor devices. The changes in demand may require our management to adjust spending and other resources allocated to operating activities, which can be made more challenging due to the multi-year nature of investments made in certain technology programs and other initiatives.

Previous wording

During periods of rapid growth or decline in demand for our products and services, we may face significant challenges in maintaining adequate financial and business controls, management processes, information systems, and procedures for training, assimilating, and managing our workforce, and in appropriately sizing our supply chain infrastructure and facilities, work force, and other components of our business on a timely basis. If we do not adequately meet these challenges during periods of increasing or declining demand, our gross margins and earnings may be negatively impacted.

Previous wording

We continuously reassess our strategic resource allocation choices in response to the changing business environment. If we do not adequately adapt to the changing business environment, we may lack the infrastructure and resources to scale up our business to meet customer expectations and compete successfully during a period of growth, or we may expand our capacity and resources too rapidly and/or beyond what is appropriate for the actual demand environment, resulting in excess fixed costs.

Current wording

We regularly assess our strategic resource allocation choices in response to the changing business environment. If we do not adequately adapt to the changing business environment, we may lack the infrastructure and resources to scale up our business to meet customer expectations and compete successfully during a period of growth, which could have a material adverse effect on our business, reputation, results of operations, financial condition, and/or our market share, or we may expand our capacity and resources too rapidly and/or beyond what is appropriate for the actual demand environment, which could result in excess fixed costs and have a material adverse effect on our results of operations and financial condition. For example, the growth of AI technologies and related infrastructure has been and is expected to continue to be a significant driver of capital equipment expenditures by semiconductor manufacturers across both the memory and non-memory market segments and requires us to respond (sometimes rapidly) to changes in demand for our products and services, including by expanding our equipment manufacturing capabilities and hiring additional personnel. If we are unable to effectively scale our business to meet our customers’ requirements in response to AI-driven demand, we may lose market share, and our business, reputation, results of operations, and financial condition could be harmed.

Previous wording

Especially during transitional periods, resource allocation decisions can have a significant impact on our future performance, particularly if we have not accurately anticipated industry changes. Our success will depend, to a significant extent, on the ability of our executive officers and other members of our senior management to identify and respond to these challenges effectively.

Previous wording

Our business depends on the capital equipment expenditures of semiconductor manufacturers, which in turn depend on the current and anticipated market demand for integrated circuits. With the consolidation of customers within the industry, the semiconductor capital equipment market may experience rapid changes in demand driven both by changes in the market generally and the plans and requirements of particular customers. The economic, regulatory, political, and business conditions occurring nationally, globally, or in any of our key sales regions, which are often unpredictable, have historically impacted customer demand for our products and services and normal commercial relationships with our customers, suppliers, and creditors. Additionally, in times of economic uncertainty, our customers’ budgets for our products, or their ability to access credit to purchase them, could be adversely affected. This would limit their ability to purchase our products and services. As a result, changing economic, regulatory, political or business conditions can cause material adverse changes to our results of operations and financial condition, including, but not limited to:

Fluctuating levels of investment by semiconductor manufacturers may materially affect our aggregate shipments, revenues, operating results, and earnings. Where appropriate, we will attempt to respond to these fluctuations with cost management programs aimed at aligning our expenditures with anticipated revenue streams, which sometimes result in restructuring charges. Even during periods of reduced revenues, we must continue to invest in R&D and maintain extensive ongoing worldwide customer service and support capabilities to remain competitive, which may temporarily harm our profitability and other financial results.

Sales to a limited number of large customers constitute a significant portion of our overall shipments, revenue, cash flows and profitability. As a result, the actions of even one customer may subject us to variability in those areas that is difficult to predict. In addition, large customers may be able to negotiate requirements that result in decreased pricing, increased costs, and/or lower margins for us and limitations on our ability to share technology with others. Similarly, significant portions of our credit risk may, at any given time, be concentrated among a limited number of customers so that the failure of even one of these key customers to pay its obligations to us could significantly impact our financial results.

Similarly, our customers may partner with, or follow the lead of, educational or research institutions that establish processes for accomplishing various tasks or manufacturing steps. If those institutions utilize a competitor’s equipment when they establish those processes, it is likely that customers will tend to use the same equipment in setting up their own manufacturing lines. Even if they select our equipment, the institutions and the customers that follow their lead could impose conditions on acceptance of that equipment, such as adherence to standards and requirements or limitations on how we license our proprietary rights, that increase our costs or require us to take on greater risk. These actions could adversely impact our market share and financial results.

Such causes may include mistakes or unauthorized actions by our employees or contractors, phishing schemes and other third-party attacks, and degradation or loss of service or access to data due to viruses, malware, denial of service attacks, destructive or inadequate code, power failures, or physical damage to computers, hard drives, communication lines, or networking equipment, in each case with respect to us or the third-party product and service providers upon which we rely. Such causes may also include the use of techniques that change frequently or may be disguised or difficult to detect, or designed to remain dormant until a triggering event, or that may continue undetected for an extended period of time. In addition, to the extent AI capabilities improve and are increasingly adopted, they may be used to identify vulnerabilities and to implement increasingly sophisticated cybersecurity attacks. Further, the use of AI by us, our customers, suppliers, and third-party providers, among others, may also introduce unique vulnerabilities whose existence or exploitation could have a material adverse effect on our business or operations.

The technology, data, intellectual property and other sensitive information we seek to protect, and the information systems used to store, process, or transmit such information, are subject to loss, unauthorized access, unauthorized release, misappropriation, misuse, disruption, breach, degradation, or failure, any of which could have a material adverse effect on our business or operations. Such events may result from various possible causes, including mistakes or unauthorized actions by our employees, contractors, or other third parties, or cyberattacks or other malicious activities by third parties, including industrial, corporate, or other espionage, criminal hackers, or state-sponsored intrusions, by methods that include exploitation of known or unknown software or hardware vulnerabilities, viruses, malware, ransomware, social engineering (such as phishing schemes), credential harvesting, denial of service attacks, destructive or inadequate code, software or hardware failure, power failures, or physical damage to computers, hard drives, communication lines, or networking equipment, in each case with respect to us or the third-party product and service providers upon which we rely. We or our third-party product and service providers may not be able to anticipate, identify, or implement effective preventive measures against cyberattacks or data security incidents and, even if timely identified, we or our third-party product and service providers may not be able to remediate such attacks or incidents in a timely and effective manner, or to mitigate or avoid adverse impacts resulting from any such attacks or incidents. These threats continue to evolve and may include the use of tools and techniques that change frequently or may be disguised or difficult to detect, or designed to circumvent security controls, evade detection, or remove forensic evidence, or remain dormant until a triggering event, or that may continue undetected for an extended period of time, which may hinder our or our third-party product and service providers’ ability to identify, investigate, and remediate attacks or incidents in a timely and effective manner, or to mitigate or avoid adverse impacts resulting from any such attacks or incidents. In addition, the development and deployment of AI models, tools, and other applications expose us, our customers, suppliers, and other third-party providers to increased and novel risks and vulnerabilities, including prompt injection, hallucinations, errors, and other issues related to AI agents, as well as the risk of compromise of valuable intellectual property. For example, the autonomous nature of agentic AI increases the risk that agents learn to circumvent security controls, and certain generative AI systems and large language models may, in order to satisfy user prompts, access or retrieve data using the credentials, permissions, or access rights of the user or connected systems, which may increase the risk of unauthorized access…

For example, the conflict that began in February 2026 between the United States, Israel, a number of states in the Persian Gulf, and Iran has led to significant regional instability and disruption in the Middle East, including the closure of or restrictions on the Strait of Hormuz, threatened or actual attacks on vessels in the Red Sea, and threatened or actual attacks on transportation and energy infrastructure, which has significantly and adversely affected the supply and prices of oil, refined oil products and byproducts, liquid natural gas, as well as certain other industrial commodities, such as aluminum, helium, bromine, and sulfur. Some of these commodities are important to the semiconductor industry. As a result, this instability and disruption has adversely affected, and may in the future materially and adversely affect, our business, results of operations, and financial condition. The extent to which we may be affected by this conflict will depend on various factors, including the scope, severity, and duration of the conflict and the extent to which the conflict, or additional laws, sanctions, or trade restrictions arising from or related to the conflict, further disrupt the availability or cost of critical inputs used in the semiconductor industry. Continuation or escalation of this conflict may also magnify the impact of other risks identified in this 2026 Form 10-K.

Tariffs, export controls, additional taxes, trade barriers, sanctions, the termination or modification of trade agreements, trade zones, and other duty mitigation initiatives, and any reciprocal retaliatory actions, can increase our manufacturing costs, decrease margins, reduce the competitiveness of our products, disrupt our supply chain operations, or inhibit our ability to sell products or provide services, which has had and in the future could have a material adverse effect on our business, results of operations, or financial conditions. Certain of our international sales depend on our ability to obtain export licenses from the U.S. or foreign governments, and our inability to obtain such licenses, or an expansion of the number or kinds of sales for which export licenses are required, has limited and could in the future further limit the market for our products and has had and could in the future have an adverse impact on our revenues. As is discussed below under the heading “Our Sales to Customers in China, a Significant Region for Us, Have Been Impacted, and are Likely to Be Materially and Adversely Affected by Export License Requirements and Other Regulatory Changes, or Other Governmental Actions in the Course of the Trade Relationship Between the U.S. and China,” the U.S. government has in recent years imposed new controls, including expanded export license requirements and restrictions on sales to certain Chinese entities that significantly impact trade with China. In addition, the U.S. government has an ongoing process of assessing technologies that may be subject to new or additional export controls, and it is possible that such additional controls, if and when imposed, could further adversely impact our ability to sell our products outside the U.S. The implementation by the U.S. government of broad export controls restricting access to our technology (such as recent controls limiting exports to China) may cause customers with international operations to reconsider their use of and reliance on our products, which could adversely impact our future revenue and profits and strengthen competitors who are not subject to such restrictions. Furthermore, there are risks that foreign governments may, among other things, take retaliatory actions; insist on the use of local suppliers; compel companies to partner with local companies to design and supply equipment on a local basis, requiring the transfer of intellectual property rights and/or local manufacturing; utilize their influence over their judicial systems to respond to intellectual property disputes or issues; and provide special incentives to government-backed local customers to buy from local competitors, even if their products are inferior to ours; all of which could adversely impact our ability to compete as well as our revenues and margins.

Additionally, certain materials are primarily available in a limited number of countries, including rare earth elements, minerals, and metals. The supplies, equipment, raw materials and other inputs necessary for the businesses of our customers and other downstream parties could become more difficult to obtain for various reasons not limited to business interruptions of suppliers, reduced availability of labor, transit disruptions, consolidation in their supply chain, export controls, sanctions, trade restrictions, tariffs, geopolitical tensions, economic circumstances, conflict, or political conditions. If the ability of downstream parties to source the inputs needed to produce their products is impaired, then demand for our products may be adversely impacted. This could have a material adverse effect on our business, results of operations or financial condition.

Disruptions to Our Supply Chain and Outsource Providers Could Impact Our Ability to Meet Demand, Increase Our Costs, and Adversely Impact Our Revenue and Results of Operations

Previous wording

Our supply chain has played and will continue to play a key role in our product development, manufacturing operations, field installation and support. Our business depends on our timely supply of products and services to meet the demand from our customers, which depends in significant part on the timely delivery of parts, materials and services, including components and subassemblies, from our direct suppliers to us, and to our direct suppliers by other companies. In addition, outsource providers have played and will continue to play a key role both in the manufacturing and customer-focused operations described above, and in many of our transactional and administrative functions, such as information technology, facilities management, and certain elements of our finance organization. These providers and suppliers might suffer financial setbacks, be acquired by third parties, become subject to exclusivity arrangements that preclude further business with us, or be unable to meet our requirements or expectation due to their independent business decisions or force majeure events that could interrupt or impair their continued ability to perform as we expect. We may also experience significant interruptions of our manufacturing operations, delays in our ability to deliver or install products or perform services or to recognize revenue, increased costs or customer order cancellations as a result of:
