Item 1A. RISK FACTORS

Semiconductor Industry and Macroeconomic Risks

Our operating results and financial condition could be adversely impacted by volatile worldwide economic conditions and unpredictable spending by our customers due to uncertainties in the macroeconomic environment.

Though the semiconductor industry’s cycle can be independent of the general economy, global economic conditions may have a direct impact on demand for semiconductor units and ultimately demand for semiconductor capital equipment and tools. Accordingly, our business and financial performance is impacted, both positively and negatively, by fluctuations in the macroeconomic environment. Expenditures by our customers depend on the current and anticipated market demand for semiconductors and products that use semiconductors, LEDs and batteries, including mobile devices, personal computers, consumer electronics, telecommunications equipment, automotive components, electric vehicles and other industrial products. Reductions or other fluctuations in our customers' spending as a result of uncertain conditions and volatility in the macroeconomic environment, including from government, economic or fiscal instability, economic recession, actual or potential inflation, rising interest rates, slower growth in certain geographic regions, global trade issues, global health crises and pandemics, restricted global credit conditions, reduced demand, excess inventory, higher energy prices, or other conditions, could adversely affect our business, financial condition and operating results. Further, our profitability can be affected by volatility because we incur a certain amount of fixed costs that we cannot modulate up and down to meet increases or decreases in demand. The impact of broad-based weakening in the global macroeconomic environment could make our customers cautious and delay orders until the economic outlook becomes clearer. Significant downturns in the market for semiconductor devices or in general economic conditions reduce demand for our products and can materially and adversely affect our business, financial condition and operating results. Our visibility into future demand is generally limited and forecasting is difficult, and we believe historic, industry-wide volatility will persist.

International political instability, geopolitical tensions, terrorist acts and acts of war may adversely affect our business, financial condition or results of operations.

The threat of terrorism or acts of war, risks and rumors of war, escalation and civil disturbances, including the prolonged tensions in the Middle East and the Ukraine/Russia conflict, increases the uncertainty in our markets and could adversely affect our business. On October 7, 2023, an escalated armed conflict between Israel and the Hamas terrorist organization commenced, leading to a series of extended hostilities along Israel’s border with the Gaza Strip. Though a ceasefire took effect on October 10, 2025, there have been subsequent claims of breaches on both sides.

Many multinational companies in the semiconductor industry have research, design and development centers situated in Israel. The Company has a manufacturing facility and a business office in Haifa, and our capillaries are manufactured at this facility, in addition to our facility in China.

The intensity, duration and outcome of the ongoing war is uncertain and its continuation or escalation may have a material adverse effect on our business and operations. While we are currently maintaining business and operations in Israel without material damage or interruptions at our Israeli facility, our assets and operations in Israel could be vulnerable to future property damage, inventory loss, business disruption, and expropriation.

As the intensity of the war has been rapidly evolving, including the potential for heightened geopolitical tensions in the Middle East, we continue to review reports concerning our operations and business partners and remain vigilant. Where necessary, we will ramp up our manufacturing capabilities in China as part of our general business contingency strategy.

The risk of cybersecurity incidents may also increase in connection with the ongoing war. These attacks may impact critical infrastructure and financial institutions globally, which in turn could adversely affect our operations. While we have taken actions to mitigate such potential risks, the proliferation of malware from the war into systems unrelated to the war, or cyberattacks targeted against U.S. companies, could adversely affect our operations.

Even if the war moderates, or a peaceful resolution in the region is reached, the detrimental impact to the global financial markets may be far-reaching, and may not recover immediately. The potential effects of these conditions could have a material adverse effect on our business, results of operations and financial condition.

We depend on our suppliers, including sole source suppliers, for raw materials, components and subassemblies. If our suppliers do not deliver their products to us, or deliver non-compliant or defective products, we would be unable to deliver our products to our customers.

Our products are complex and require raw materials, components and subassemblies having a high degree of reliability, accuracy and performance. We rely on subcontractors to manufacture many of these components and subassemblies and we rely on sole source suppliers for certain key technology parts and raw materials. As a result, we are exposed to a number of significant risks, including:

•decreased control over the manufacturing process for components and subassemblies;

•changes in our manufacturing processes in response to changes in the market, which may delay our shipments;

•our inadvertent use of defective or contaminated raw materials;

•the relatively small operations and limited manufacturing resources of some of our suppliers, which may limit their ability to manufacture and sell subassemblies, components or parts in the volumes we require and at acceptable quality levels and prices;

•restrictions on our ability to rely on suppliers due to changes in trade regulation as well as laws and regulations enacted in response to concerns related to climate change, conflict minerals, or responsible sourcing practices;

•the inability of suppliers to meet our or other customer demand requirements;

•reliability or quality issues with certain key subassemblies provided by single source suppliers as to which we may not have any short-term alternative;

•shortages caused by disruptions at our suppliers and subcontractors for a variety of reasons, including public health emergencies and associated containment measures, war or geopolitical tensions (such as the prolonged tensions in the Middle East and the Ukraine/Russia conflict), significant natural disasters (including as a result of climate change) or significant price changes (including as a result of inflationary pressures);

•delays in the delivery of raw materials or subassemblies, which, in turn, may delay shipments to our customers;

•loss of suppliers as a result of consolidation of suppliers in the industry; and

•loss of suppliers because of their bankruptcy or insolvency.

If any of these risks were to materialize, we might be unable to deliver our products to our customers on time and at expected cost, or at all. While we observed some easing of the industry-wide supply constraints in fiscal 2024, we expect some constraints to continue from time to time and the duration of such constraints or their long-term impact on our business cannot be predicted at this time.

As part of our supply chain management, we may from time to time increase our inventory levels to mitigate against anticipated future component shortages. These increases in our inventory levels may lead to an excess of materials in the future in the event that the demand for our products is lower than our expectations or if we otherwise fail to anticipate future customer demand properly. Excess inventory levels could result in inventory write-downs at discounted prices, which could adversely affect our cash flows or gross margins. As a result, our business, financial condition and operating results would be materially and adversely affected.

The semiconductor industry is volatile with sharp periodic downturns and slowdowns. Cyclical industry downturns are made worse by volatile global economic conditions.

The semiconductor industry is volatile, with periods of rapid growth followed by industry-wide retrenchment. These periodic downturns and slowdowns have in the past adversely affected our business, financial condition, human resource allocation and operating results. Downturns have been characterized by, among other things, diminished product demand, excess production capacity, and accelerated erosion of selling prices. Historically these downturns have severely and negatively affected the industry’s demand for capital equipment, including assembly equipment and, to a lesser extent, tools. In any case, we believe the historical volatility of our business, both upward and downward, will persist. Consequently, our revenues may decline, and our results of operations and financial condition may be adversely affected.

Table of Contents

Difficulties in forecasting demand for our product lines may lead to periodic inventory shortages or excesses.

We typically operate our business with limited visibility of future demand. We do not have long-term contracts with many of our customers. As a result, demand for our products in future periods is difficult to predict and we sometimes experience inventory shortages or excesses. We generally order supplies and otherwise plan our production based on internal forecasts for demand, especially for supplies with a longer lead time. We have in the past failed, and may again in the future fail, to accurately forecast demand for our products. This has led to, and may in the future lead to, delays in product shipments or, alternatively, an increased risk of inventory obsolescence. As part of our supply chain management, we have increased our inventory levels in an effort to mitigate component shortages, which may increase the risk of inventory obsolescence. If we fail to accurately forecast demand for our products, our business, financial condition and operating results may be materially and adversely affected.

Our quarterly operating results fluctuate significantly and may continue to do so in the future.

In the past, our quarterly operating results have fluctuated significantly. We expect that our quarterly results will continue to fluctuate. Although these fluctuations are partly due to the cyclical and volatile nature of the semiconductor industry, they also reflect other factors, many of which are outside of our control.

Some of the factors that may cause our net revenue and operating margins to fluctuate significantly from period to period are:

•market downturns;

•industry inventory levels;

•the mix of products we sell because, for example:

◦certain lines of equipment or certain aftermarket tools within our business segments are more profitable than others; and

◦some sales arrangements have higher gross margins than others;

•cancelled or deferred orders;

•variations in sales channel or mix of direct sales and indirect sales;

•seasonality;

•changes in trade regulations;

•competitive pricing pressures may force us to reduce prices;

•higher than anticipated costs of development, achieving customer acceptance or production of new products;

•the availability and cost of the components for our products;

•delays in the development and manufacture of our new products and upgraded versions of our products and market acceptance of these products when introduced;

•customers’ delay in purchasing our products due to anticipation that we or our competitors may introduce new or upgraded products; and

•our competitors’ introduction of new products.

Many of our expenses, such as research and development, selling, general and administrative expenses, and interest expense, do not vary directly with our net revenue. Our research and development efforts include long-term projects lasting a year or more, which require significant investments. In order to realize the benefits of these projects, we believe that we must continue to fund them even during periods when our revenue has declined. As a result, a decline in our net revenue would adversely affect our operating results as we continue to make these expenditures. In addition, if we were to incur additional expenses in a quarter in which we did not experience comparable increased net revenue, our operating results would decline. In a downturn, we may have excess inventory, which could be written off. Some of the other factors that may cause our expenses to fluctuate from period-to-period include:

•timing and extent of our research and development efforts;

•retrenchment, severance, restructuring, and other costs of relocating our manufacturing or warehouse facilities;

Table of Contents

•inventory write-offs due to obsolescence, project cancellations or other causes; and

•an increase in the cost of labor or materials.

Because our net revenue and operating results are volatile and difficult to predict, we believe consecutive period-to-period or year-over-year comparisons of our operating results may not be a good indication of our future performance.

Competitive Risks

Our average selling prices usually decline over time and may continue to do so.

Typically, our average selling prices have declined over time due to continuous price pressure from our customers, our competitors and general cost reductions within our industry’s supply chains. The Chinese government’s initiatives around self-sustainability in the semiconductor sector are propelling China to expand its domestic manufacturing capacity. With considerable incentives from the Chinese government, manufacturers based in China are able to lower selling prices, thereby increasing overall competition. This has resulted in a lowering of our average selling prices in China. We seek to offset this decline by continually reducing our cost structure by consolidating operations in lower cost areas, reducing other operating costs, by pursuing product strategies focused on product performance and customer service, and developing new products for which we are able to charge higher prices. These efforts may not enable us to fully offset price declines, and if they do not, our financial condition and operating results may be materially and adversely affected.

We may not be able to rapidly develop, manufacture and gain market acceptance of new and enhanced products required to maintain or expand our business.

We believe our continued success depends on our ability to continuously develop and manufacture new products and product enhancements on a timely and cost-effective basis. We must introduce these products and product enhancements into the market in a timely manner in response to customers’ demands for higher performance assembly equipment and leading-edge materials customized to address rapid technological advances in integrated circuits, and capital equipment designs. Our competitors may develop new products or enhancements to their products that offer improved performance and features, or lower prices which may render our products less competitive. The development and commercialization of new products require significant capital expenditures over an extended period of time, and some products we seek to develop may never become profitable. In addition, we may not be able to develop and introduce products incorporating new technologies in a timely manner that will satisfy our customers’ future needs or achieve market acceptance. If we are not able to develop and sell our products that meet the demands of our customers, it would result in lower net revenues and our operating results would be adversely affected.

We may be unable to continue to compete successfully in the highly competitive semiconductor equipment and packaging materials industries.

The semiconductor equipment and packaging materials industries are very competitive. In the semiconductor equipment industry, significant competitive factors include price, speed/throughput, production yield, process control, footprint, delivery time, innovation, quality and customer support. In the semiconductor packaging materials industry, significant competitive factors include price, delivery and quality.

In each of our markets, we face competition and the threat of competition from established competitors and potential new entrants. In addition, established competitors may combine to form larger, better-capitalized companies, or enter into strategic collaboration with major process partners. Some of our competitors have or may have significantly greater financial, engineering, manufacturing and marketing resources than we do. Some of these competitors are Asian and European companies that have had, and may continue to have, an advantage over us in supplying products to local customers who appear to prefer to purchase from local suppliers. Some of these competitors compete across many of our product lines, while others are primarily focused in a specific product area, all of which could result in lowering the barriers to entry. Some governments have provided, and will continue to provide, financial assistance or other support to some of our competitors or to new entrants, to advance the nation's growth in the semiconductor equipment and packaging materials industries.

Table of Contents

We expect our competitors to improve their current products’ performance, and to introduce new products and materials with improved price and performance characteristics. Our competitors may independently develop technology similar to or better than ours. They may also appropriate our technology and our intellectual property to compete against us and we may not have adequate legal recourse. New product and material introductions by existing competitors or by new market entrants could hurt our sales. If a semiconductor manufacturer or subcontract assembler selects a competitor’s product or materials for a particular assembly operation, we may not be able to sell products or materials to that manufacturer or assembler for a significant period of time. Manufacturers and assemblers sometimes develop lasting relationships with suppliers and assembly equipment providers in our industry and often go years without requiring replacement. In addition, we may have to lower our prices in response to price cuts by our competitors, which may materially and adversely affect our business, financial condition and operating results. If we cannot compete successfully, we could lose customers and experience reduced margins and profitability.

Geographic, Trade and Customer Risks

Substantially all of our sales, distribution channels and manufacturing operations are located outside of the U.S., which subjects us to risks, including risks from changes in trade regulations, currency fluctuations, political instability and conflicts.

From time to time, our customers may request that we deliver our products to countries where they own or operate production facilities or to countries where they utilize third-party subcontractors or warehouses as part of their supply chain. Our customer base in the Asia/Pacific region has become more geographically concentrated over time as a result of general economic and industry conditions and trends. Over 90% of our net revenue is derived from shipments to customers located outside of the U.S., primarily in the Asia/Pacific region. Approximately 53.5% and 53.3% of our net revenue for fiscal 2025 and 2024, respectively, was derived from shipments to customers headquartered in China.

We expect our future performance to depend on our ability to continue to compete in foreign markets, particularly in the Asia/Pacific region. Some of these economies have been highly volatile, resulting in significant fluctuation in local currencies, and political and economic instability. Some of these economies may also increase trade protectionism, thereby increasing barriers to entry, amplifying supply chain risks and adversely affecting the demand for our products. These conditions may continue or worsen, which may materially and adversely affect our business, financial condition and operating results.

We also rely on non U.S. suppliers for materials and components used in our products, and substantially all of our manufacturing operations are located in countries other than the U.S. We currently manufacture our ball, wedge, APAMATM and APTURATM bonders in Singapore, our dicing blades, capillaries and bonding wedges in China, our Hybrid and Electronic Assembly solutions in the Netherlands, our capillaries in Israel, and our advanced dispensing equipment in Taiwan. We also rely on independent foreign distribution channels for certain of our product lines. As a result, a major portion of our business is subject to the risks associated with international commerce, particularly Asia/Pacific region, such as:

• stringent and frequently changing trade regulations;

• less protective foreign intellectual property laws, and the enforcement of patent and other intellectual property rights;

• longer payment cycles in foreign markets and potential default risks;

• foreign exchange restrictions and capital controls, monetary policies and regulatory requirements;

• restrictions or significant taxes on the repatriation of our assets, including cash;

• tariff and currency fluctuations;

• trade wars or trade conflicts;

• difficulties of staffing and managing dispersed international operations, including labor work stoppages and strikes in our factories or the factories of our suppliers;

• changes in our structure or tax incentive arrangements;

• possible disagreements with tax authorities;

• episodic events outside our control such as, for example, outbreaks of coronaviruses, influenza, monkeypox or other illnesses;

Table of Contents

• natural disasters such as earthquakes, fires or floods, including as a result of climate change;

• war, risks and rumors of war and civil disturbances, including the prolonged tensions in the Middle East and the Ukraine/Russia conflict, or other events that may limit or disrupt manufacturing, markets and international trade;

• act of terrorism that impact our operations, customers or supply chain or that target U.S. interests or U.S. companies;

• seizure of our foreign assets, including cash;

• the imposition of sanctions of countries in which we do business;

• changing political conditions and rising geopolitical tensions; and

• legal systems which are less developed and may be less predictable than those in the U.S.

In addition, there remains a potential risk of conflict and instability in the relationship between Taiwan and China which could disrupt the operations of our customers and/or suppliers in both Taiwan and China, our manufacturing operations in Taiwan and China, and our future plans in the region.

Our international operations also depend on favorable trade relations between the U.S. and those foreign countries in which our customers, subcontractors and materials suppliers have operations. In 2025, the U.S. imposed additional tariffs on a number of countries. Impacted countries have imposed, and in the future may impose, retaliatory tariffs, and such actions could give rise to an escalation of other trade measures by the countries subject to such tariffs. In addition to tariffs, the U.S. has imposed export controls targeted at specific industries, including the semiconductor industry.

These tariffs and other adverse trade actions, as well as the threat of trade wars against foreign countries/regions, have created even more uncertainties in international trade, which may affect our business. For example, the imposition of tariffs and export controls have indirectly led to an increase in the cost of our products, which if improperly managed, could in turn materially and adversely affect our ability to sell our products in foreign markets.

Catastrophic events, such as pandemics and extreme weather events as a result of climate change, can have a material adverse effect on our operations and financial results.

Our operations and business, and those of our customers and suppliers, can be disrupted by natural disasters, public health issues, interruptions of service from utilities, or other catastrophic events including as a result of climate change. In addition, global climate change can result in natural disasters occurring more frequently, with greater intensity and with less predictability. We also operate in seismic zones including Taiwan, which is located within a complex zone of convergence between the Philippines Sea Plate and Eurasian Plate. For example, in January 2025, a magnitude 6.4 earthquake struck Tainan, Taiwan, resulting in a temporary suspension of business and services. Although our advanced dispensing manufacturing operations in Taiwan were not affected, the earthquake resulted in the temporary suspension of other semiconductor factories and suppliers who operate in Taiwan. The long-term effects of climate change on the global economy and the semiconductor industry in particular are unclear but could be severe, and could exacerbate the other risk factors described herein. Catastrophic events could make it difficult or impossible to manufacture or deliver products to our customers, receive materials from our suppliers, or perform critical functions, whether on a timely basis or at all, which could adversely affect our revenue and operations. Some of the systems we maintain as part of our business recovery plans cannot guarantee us protection from such disruptions. Furthermore, even if our operations are unaffected or if we managed to recover our operations quickly, if our customers or suppliers cannot timely resume their own operations due to a catastrophic event, we may be unable to fulfil our customers’ orders, and may experience reduced or cancelled orders or other disruptions to our supply chain that may adversely affect our results of operations.

We are subject to export restrictions that may limit our ability to sell to certain customers, and trade wars, in particular the U.S.-China trade war, could adversely affect our business.

The U.S. and several other countries levy tariffs on certain goods and impose other trade restrictions that may impact our customers’ investment in manufacturing equipment, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies.

In particular, trade tensions between the U.S. and China have been ongoing. There has been a further escalation of trade tensions between the U.S. and China since 2018, with U.S. tariffs on Chinese goods and retaliatory Chinese tariffs on U.S. goods.

Table of Contents

We cannot predict what further actions may ultimately be taken with respect to tariffs or trade relations between the U.S. and other countries, what products may be subject to such actions, or what actions may be taken by other countries in response. Further changes in trade policy, tariffs, additional taxes, restrictions on exports or other trade barriers, or restrictions on supplies, equipment, and raw materials, may limit our ability to produce products, increase our selling and/or manufacturing costs, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies, which could have a material adverse effect on our business, results of operations, or financial condition.

Though nearly all of our manufacturing activities take place outside of the U.S., certain of our advanced packaging products are subject to the EAR because they are based on U.S. technology or contain more than a de minimis amount of controlled U.S. content. The EAR require licenses for, and sometimes prohibit, the export of certain products. The CCL sets forth the types of goods and services controlled by the EAR, including civilian science, technology, and engineering dual use items. For products listed on the CCL, a license may be required as a condition to export depending on the end destination, end use or end user and any applicable license exceptions.

In 2020, the U.S. Department of Commerce Bureau of Industry and Security (“BIS”) amended the EAR to expand controls on certain foreign products based on U.S. technology and sold to Huawei and certain other companies. In October 2022, the BIS amended the EAR again to extend those foreign controls to numerous companies on BIS’ so called Entity List. The 2020 and 2022 amendments impact some of our advanced packaging products, which are based on U.S. technology and are within the scope of the expanded EAR controls on Huawei and other Entity List companies. Therefore, these products cannot be sold to Huawei and other Entity List companies, and are subject to certain end use restrictions. To date, these amendments to the EAR have not had a material direct impact on our business, financial condition or results of operations and we do not expect that they will, although they could have indirect impact, including increasing tensions in U.S. and Chinese trade relations, potentially leading to negative sentiments towards U.S. based companies among Chinese consumers. Additionally, some end users may prefer to avoid the U.S. supply chain in its entirety to avoid the application of these regulations.

In November 2023, the BIS issued additional rules to update export controls on advanced computing semiconductors and semiconductor manufacturing equipment, as well as items that support supercomputing applications and end uses, to arms embargoed countries, including China. Further in December 2024, the BIS added new export controls pertaining to high-bandwidth memory, semiconductor manufacturing equipment and related items that enable advanced-node integrated circuit production. While the BIS rescinded its "Framework for AI Diffusion" in May 2025, there is a possibility of a replacement rule or other similar rules being introduced in the future. In September 2025, the BIS promulgated the new “Affiliates Rule”, which applied restrictions on exports (and reexports and transfers) to any foreign entity that is at least 50% owned, individually or in the aggregate, by one or more entities named on the Entity List, the Military End-User List, or those designated with certain identifiers on the Specially Designated Nationals List of the Office of Foreign Assets Control. In November 2025, the BIS suspended the application of the Affiliates Rule until November 2026.

We are taking appropriate measures to comply with all applicable BIS Rules. Where required, we will apply for export licenses from the BIS to avoid disruption to our customers’ operations. Export licenses may be subject to a prolonged review and appeals process, to which there cannot be an assurance as to whether an export license may be granted, granted with conditions or eventually revoked due to subsequent challenge.

Additionally, the rules promulgated by the BIS are typically complex, and the BIS could revise or expand them in response to public comments. Likewise, the BIS may issue guidance clarifying the scope of the rules. Such revisions, expansions or guidance could change the impact of the rules for our business. Future changes in, and responses to, the various export regulations, tariffs, or other trade regulations between the U.S. and other countries may be unpredictable. Such further changes may limit our ability to produce products, increase our selling or manufacturing costs, decrease margins, reduce the competitiveness of our products and cause our sales to decline, and therefore could have a material adverse effect on our business, financial condition or results of operations.

Because a small number of customers account for most of our sales, our net revenue could decline if we lose a significant customer.

The semiconductor manufacturing industry is highly concentrated, with a relatively small number of large semiconductor manufacturers and their subcontract assemblers and vertically integrated manufacturers of electronic systems purchasing a substantial portion of our semiconductor assembly equipment and packaging materials. Sales to a relatively small number of customers have historically accounted for a significant percentage of our net revenue. Sales to our ten largest customers comprised 54.8% and 53.6% of our net revenue for fiscal 2025 and fiscal 2024, respectively.

Table of Contents

We expect that a small number of customers will continue to account for a high percentage of our net revenue for the foreseeable future. Thus, our business success depends on our ability to maintain strong relationships with our customers and closely understand their present and anticipated utilization rates. Any one of a number of factors could adversely affect these relationships. If, for example, during periods of escalating demand for our equipment, we were unable to add inventory or increase our production capacity quickly enough to meet the needs of our customers, or if we are not able to fulfil our customers' orders due to supply chain constraints, they may turn to other suppliers making it more difficult for us to retain their business. We may also make commitments from time-to-time to our customers regarding minimum volumes and performance standards, and if we are unable to meet those commitments, we may incur liabilities to our customers. If we lose orders from a significant customer that we are not able to replace, or if a significant customer reduces its orders substantially, or if we incur liabilities for not meeting customer commitments, these losses, reductions or liabilities may materially and adversely affect our business, financial condition and operating results.

We maintain a backlog of customer orders that is subject to cancellation, reduction or delay in delivery schedules, which may result in lower than expected revenues.

We manufacture products primarily pursuant to purchase orders for current delivery or to forecast, rather than pursuant to long-term supply contracts. As a result, we must commit resources to the manufacture of products without binding purchase commitments from customers. The semiconductor industry is occasionally subject to double-booking and rapid changes in customer outlooks or unexpected build ups of inventory in the supply channel as a result of shifts in end market demand and macro-economic conditions. Accordingly, many of these purchase orders or forecasts may be revised or cancelled without penalty. Even in cases where our standard terms and conditions of sale or other contractual arrangements do not permit a customer to cancel an order without penalty, we may from time to time accept cancellations to maintain customer relationships or because of industry practice, custom or other factors. The broad-based weakening in the global macroeconomic environment may result in lower than expected demand for our products, and our inability to sell products after we devote significant resources to them could have a material adverse effect on our levels of inventory, revenues and profitability.

The cessation of our Electronics Assembly equipment business may adversely affect our business, results of operations and financial condition.

On March 25, 2025, the Board of Directors of the Company approved a strategic plan related to the cessation of the Company's Electronics Assembly ("EA") equipment business. As part of the plan, the Company began the process of winding down the EA equipment business in an effort to prioritize core semiconductor assembly business opportunities and enhance overall through-cycle financial performance. The cessation of the EA equipment business is subject to a consultation process with the applicable works council and union representatives, which the Company initiated in the third fiscal quarter of 2025 and, as of October 4, 2025, had substantially completed. The wind down activities remain ongoing and are expected to be substantially completed by fiscal 2026, after which there will be some service support activities to serve out the remaining customer obligations.

As we work towards the cessation of the EA equipment business, we may discover other facts that could require us to incur additional expenses and/or record additional charges that may be different from our initial expectations. In addition, we may not be able to complete the wind down in all respects or on time, due to factors outside of our control. If actual amounts were to differ from our estimates, or if the full and complete wind down takes longer than expected, our results of operations and financial condition could be materially and adversely affected.

Human Capital Risks

Our business depends on attracting and retaining management, sales and technical employees as well as on the succession of senior management.

Our future success depends on our ability to hire and retain qualified management, sales, finance, accounting and technical employees, including senior management. We depend on the continued services and performance of our key personnel, including our executive officers. If one or more of our executive officers or other key employees were unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all, and our business may be seriously harmed.

Experienced personnel with the relevant and necessary skill sets in our industry are in high demand and competition for their talents is intense, especially in Asia, where most of the Company’s key personnel are located. If we are unable to continue to attract and retain the engineering, managerial, sales, supply chain, marketing, finance, field service and technical personnel we require, our business, financial condition and operating results may be materially and adversely affected.

Table of Contents

Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving senior management could hinder our strategic planning and execution. From time to time, senior management or other key employees may leave our Company, such as the recent departure of our president and chief executive officer on October 28, 2025, and the loss of any key employee could result in significant disruptions to our operations, including adversely affecting the timeliness of product releases, the successful implementation and completion of company initiatives, the effectiveness of our disclosure controls and procedures and our internal control over financial reporting, and the results of our operations. Changes in immigration policies may also impair our ability to recruit and hire technical and professional talent. In addition, hiring, training, and successfully integrating replacement critical personnel could be time consuming, may cause additional disruptions to our operations, and may be unsuccessful, which could negatively impact future revenues.

Product Risks

Alternative packaging technologies may render some of our products obsolete and materially and adversely affect our overall business and financial results.

Alternative packaging technologies have emerged that may improve device performance, reduce the size of or enhance the number of components inherent in an integrated circuit package, as compared to traditional wire bonding. These technologies include hybrid bonding, thermo-compression bonding, flip chip bonding and wafer-level packaging. Some of these alternative technologies eliminate the need for wires to establish the electrical connection between a die and its package. The semiconductor industry may, in the future, shift a significant part of its volume into alternative packaging technologies which do not employ our products. If a significant shift to alternative packaging technologies or to another technology not offered by us were to occur, demand for our equipment and related packaging materials may be materially and adversely affected. Given that a majority of our revenue comes from wire bonding, a reduced demand for our wire bonding equipment could materially and adversely affect our financial results.

We may send products and equipment to customers or potential customers for trial, evaluation or other purposes which may result in retrofit charges, impairments or write-down of inventory value if the products and equipment are not subsequently purchased by the customers.

From time to time we send certain products and equipment to customers or potential customers for testing, evaluation or other purposes in advance of receiving any confirmation of purchase or purchase orders. Such equipment, especially our advanced packaging and advanced dispensing equipment, may be at the customer location for an extended period of time per the agreements with these customers and potential customers. The customer or potential customer may refuse to buy all or partial quantities of such product or equipment and return this back to us. As a result, we may incur charges to retrofit the machines or sell the machines as second hand at a lower price, and accordingly may have to record impairments on the returned inventory, all of which would adversely affect our operating results.

Undetected problems in our products could directly impair our financial results.

If errata (deviations from product specifications) or flaws in design, production, assembly or testing of our products (by us or our suppliers) were to occur, we could experience a rate of failure in our products that would result in materially adverse consequences, including:

•incurring warranty expenses;

•writing off the value of inventory;

•disposing of products that cannot be fixed;

•retrofitting products that have been shipped;

•providing product replacements or modifications; and

•defending against litigation.

Continued improvement in manufacturing capabilities, control of material, emphasis on product safety and manufacturing quality and costs and product testing are critical factors in our future growth. Our efforts to monitor, develop, modify and implement appropriate tests and manufacturing processes for our products may not be sufficient to permit us to avoid a rate of failure in our products that results in substantial delays in shipment, significant repair or replacement costs, potential damage to our reputation or general customer dissatisfaction with our products. We may also not be able to successfully claim against our suppliers or obtain product liability or other

insurance to fully cover such risks. Any of the foregoing risks, if they were to materialize, could have a material adverse effect on our business, results of operations or financial condition.

Operations and Supply Chain Risks

We may not be able to continue to consolidate or relocate manufacturing and other facilities or entities without incurring unanticipated costs and disruptions to our business.

As part of our ongoing efforts to drive further efficiency, we may consolidate or relocate our manufacturing and other facilities or entities. Should we consolidate or relocate, we may experience unanticipated events, including the actions of governments, suppliers, employees, union representatives or customers, which may result in unanticipated costs and disruptions to our business. We may also incur restructuring charges, severance costs, asset impairments, loss of accumulated knowledge, inefficiency during transitional periods, employee attrition and other effects that could negatively impact our financial condition and results of operations.

We may be materially and adversely affected by environmental and safety laws and regulations, including laws and regulations implemented in response to climate change.

We are subject to various federal, state, local and foreign laws and regulations governing, among other things, the generation, storage, use, emission, discharge, transportation and disposal of hazardous material, investigation and remediation of contaminated sites and the health and safety of our employees. Public attention continues to focus on the environmental impact of manufacturing operations and the risk to neighbors of waste and chemical releases from such operations.

Proper waste disposal plays an important role in the operation of our manufacturing plants. Most of our facilities operate under permits that must be renewed periodically. A violation of those permits may lead to revocation of the permits, imposition of fines or penalties, or the incurrence of additional capital expenditure or other costs to comply with the permits, including the potential shutdown of operations.

Compliance with existing or future land use, environmental, climate-related and health and safety laws and regulations may: (1) result in significant costs to us for additional capital equipment or other process requirements; (2) restrict our ability to expand our operations; and/or (3) cause us to curtail our operations. We also could incur significant costs, including cleanup costs, fines or other sanctions and third-party claims for property damage or personal injury, as a result of violations of or liabilities under such laws and regulations.

Increasingly, various agencies and governmental bodies, especially in jurisdictions outside the U.S. where we continue to operate, have expressed interest in promulgating rules relating to climate change. The cost of complying, or of failing to comply, with these and other regulatory requirements or contractual obligations could adversely affect our operating results, financial condition and ability to conduct our business.

In addition, changes in environmental laws and regulations could require us, or others in our value chain, to install additional equipment, alter operations to incorporate new technologies or processes and generally enhance audit, surveillance and compliance measures.

To the extent that higher costs incurred from the above activities result in higher prices for our products, we may experience a reduction in the demand for those products, which could negatively affect our results of operations. Conversely, we may not be able to pass these increased costs onto our customers in the form of higher prices, as a result of which our results of operations may also be adversely affected.

We may acquire or divest businesses or enter into joint ventures or strategic alliances, which may materially affect our business, financial condition and operating results.

We continually evaluate our portfolio of businesses and may decide to buy or sell businesses or enter into joint ventures or other strategic alliances. We may not find suitable acquisition candidates, we may not be able to close such acquisitions, and the acquisitions we complete may not be successful. We may be unable to successfully integrate acquired businesses with our existing businesses and successfully implement, improve and expand our systems, procedures and controls to accommodate these acquisitions. If we are not able to successfully integrate any acquired businesses with ours, the anticipated benefits of the acquisitions may not be realized fully or may take longer than expected to be realized. We may also incur higher than expected costs as a result of any acquisitions or experience an overall post-completion process that takes longer than originally anticipated.

These transactions place additional demands on our management, our various functional teams and our current labor force. The combination of businesses may result in the loss of key personnel or an interruption of, or loss of momentum in, our existing businesses and/or the acquired business. In addition, we may need to divest existing businesses, which would cause a decline in revenue or profitability and may make our financial results more

Table of Contents

volatile. If we fail to integrate and manage acquired businesses successfully or to mitigate the risks associated with divestitures, joint ventures or other alliances, or if the time and costs associated with integration exceeds our expectations, or if our acquired business were to perform poorly, our business, financial condition and operating results may be materially and adversely affected.

Increasing attention to ESG matters, including any targets or other ESG initiatives, could result in additional costs or risks or adversely impact our business

Certain investors, shareholder advocacy groups, other market participants, customers and other stakeholder groups have focused increasingly on companies' environmental, social and governance (“ESG”) initiatives, including those concerning climate change, greenhouse gas emissions, human rights, and shareholder proxy access. This may result in increased costs, enhanced compliance or disclosure obligations and related costs, or other adverse impacts on our business, financial condition or results of operations.

From time to time, we create and publish voluntary disclosures regarding ESG matters. Our sustainability report continues to outline our Company’s strategies, initiatives and performance of ESG topics identified through a materiality assessment to be most relevant to the operations and stakeholders of our Company. In fiscal 2024, we performed an independent, limited external assurance of our direct (Scope 1) and purchased energy indirect (Scope 2) greenhouse gas emission data, as well as selected sustainability performance data that included paper usage, water consumption, and waste generated and disposed, under the operational control boundary of seven of our global operational sites, and published such limited external assurance in our sustainability report. However, the identification, assessment, and disclosure of such matters remains complex. Many of the statements in such voluntary disclosures are based on our expectations and assumptions, which may require substantial discretion and forecasts about costs and future circumstances.

Additionally, ESG matters continue to evolve rapidly. Organizations that provide information to investors on ESG matters may develop more discrete rating matrices, benchmarks and processes on evaluating companies on their ESG approach. This may create opportunities for misalignment or perceived failure resulting in unfavorable ESG ratings. This could foster negative investor sentiment toward us, our customers, or our industry, which could negatively impact our business and operations. To the extent ESG matters negatively impact our reputation, it may also impede our ability to compete as effectively to recruit or retain employees, which may adversely affect our operations.

Intellectual Property Risks

Our success depends in part on our intellectual property, which we may be unable to protect.

Our success depends in part on our proprietary technology. To protect this technology, we rely principally on contractual restrictions (such as nondisclosure and confidentiality provisions) in our agreements with employees, subcontractors, vendors, consultants and customers and on the common law of trade secrets and proprietary “know-how”. We also rely, in some cases, on patent and copyright protection, although this protection may in some cases be insufficient due to the rapid development of technology in our industry. We may not be successful in protecting our technology for a number of reasons, including the following:

•employees, subcontractors, vendors, consultants and customers may violate their contractual agreements or post-employment non-competition obligations, and the cost of enforcing those agreements may be prohibitive, or those agreements may be unenforceable or more limited than we anticipate;

•foreign intellectual property laws may not adequately protect our intellectual property rights;

•our patent and copyright claims may not be sufficiently broad to effectively protect our technology; our patents or copyrights may be challenged, invalidated or circumvented; or we may otherwise be unable to obtain adequate protection for our technology; and

•when our patents expire, or if they are invalidated, narrowed or circumvented, our competitors may be able to utilize the inventions protected by our patents.

Also, competitors may copy or misappropriate our trade secrets, products or designs either through lawful means of reverse engineering or through independent development. We remain vigilant and take note of similar products and solutions offered by our competitors and, based on reasonable efforts, investigate whether any of our competitors’ products or solutions is the outcome of unlawful reverse engineering.

Competitors or third parties (including ex-employees violating their surviving contractual obligations with us) may also copy or reverse engineer aspects of our products or solutions through unlawful means, or illegally use information that we regard as proprietary. While we conduct active surveillance and monitor potential threats

Table of Contents

surrounding any unauthorized use from competitors or third parties, we may not be able to detect misuse of our proprietary information before it occurs. For example, as a result of our active surveillance, we have learned that certain ex-employees in China, who had access to materials containing proprietary information and trade secrets about our products and designs, may have provided them to their current employer that is our direct competitor. We continue to fully investigate this matter and, if appropriate, pursue litigation against all parties that may be involved to protect our confidential information and trade secrets.

Despite our best efforts in active surveillance and monitoring, such policing may be difficult, time-consuming, non-definitive and non-exhaustive, and we cannot be certain that the steps we have taken will prevent misappropriation of our intellectual property.

Additionally, laws of foreign countries may not provide us with adequate remedy against unauthorized use of our intellectual property, or we may be unable to prove unauthorized use as prescribed by such foreign laws. In either case, if the protection of our intellectual property proves to be inadequate or unenforceable, others may be able to use our proprietary developments without compensation or appropriate remediation to us, resulting in potential cost advantages to our competitors and consequentially eroding our market share.

Furthermore, our partners and alliances may have rights to technology developed by us. We may incur significant expense to protect or enforce our intellectual property rights. If we are unable to protect our intellectual property rights, our competitive position may be weakened.

Third parties may claim we are infringing on their intellectual property, which could cause us to incur significant litigation costs or other expenses, or prevent us from selling some of our products.

The semiconductor industry is characterized by rapid technological change, with frequent introductions of new products and technologies. Industry participants often develop products and features similar to those introduced by others, creating a risk that their products and processes may give rise to claims they infringe on the intellectual property of others. We may unknowingly infringe on the intellectual property rights of others and incur significant liability for that infringement. If we are found to have infringed on the intellectual property rights of others, we could be enjoined from continuing to manufacture, market or use the affected product, or be required to obtain a license to continue manufacturing or using the affected product. A license could be very expensive to obtain or may not be available at all. Similarly, changing or re-engineering our products or processes to avoid infringing the rights of others may be costly, impractical or time consuming.

Occasionally, third parties assert that we are, or may be, infringing on or misappropriating their intellectual property rights. Some of these assertions may not be legitimate. In these cases, we defend or in some instances dispel, and will continue to defend or dispel, against claims or negotiate licenses where we consider these actions appropriate. Intellectual property cases are uncertain, time-consuming and involve complex legal, technical and factual questions. If we become involved in this type of litigation, it could consume significant resources and divert our attention from our business.

Information Technology and Enterprise System Risks

We may be subject to disruptions or failures in our information technology systems and network infrastructures that could have a material adverse effect on us.

We maintain and rely extensively on information technology systems and network infrastructures for the effective operation of our business. We also hold large amounts of data in data center facilities around the world, primarily in Singapore and the U.S., on which our business depends. A disruption, infiltration or failure of our information technology systems owned or used by us or any of our data centers as a result of software or hardware malfunctions, computer viruses, cyber-attacks, employee theft or misuse, power disruptions, natural disasters or accidents could cause breaches of data security and loss of critical data, which in turn could materially adversely affect our business. Our security procedures, such as virus protection software, data loss protection and our business continuity planning, such as our disaster recovery policies and back-up systems, may not be adequate or implemented properly to fully address the adverse effect of such events, which could adversely impact our operations.

In addition, our business could be adversely affected to the extent we do not make the appropriate level of investment in our technology systems as our technology systems become out-of-date or obsolete and are not able to deliver the type of data integrity and reporting we need to run our business. Furthermore, when we implement new systems and/or upgrade existing systems, we could be faced with temporary or prolonged disruptions that could adversely affect our business. For example, artificial intelligence (“AI”) may be used to generate cyberattacks with greater scale and efficacy than the traditional threat actors. In other instance, a cybersecurity threat could be

Table of Contents

introduced as the result of our business partners incorporating the output of an AI tool that includes a threat, such as introducing malicious code by incorporating an AI generated source code.

We have experienced, and expect to continue to be subject to, cybersecurity threats and incidents, ranging from employee error or misuse, to individual attempts to gain unauthorized access to information systems, to sophisticated and targeted measures known as advanced persistent threats, none of which have been material to the Company to date. However, future attempts or breaches might become more pervasive and sophisticated, especially given that threat actors may leverage other means and technologies, including artificial intelligence, to circumvent controls and avoid detection. We devote significant resources to network security and other measures to protect our systems and data from unauthorized access or misuse. However, our cybersecurity risk management, process, protocols and tools, may not be fully implemented or may not completely protect the Company against future cybersecurity incidents. Depending on its nature and scope, cybersecurity incidents could result in business disruption; misappropriation, corruption or loss of confidential information and critical data (of the Company or that belonging to its third parties); reputational damage; litigation with third parties; diminution in the value of our investment in research, development and engineering; data privacy issues; and increased cybersecurity protection and remediation costs.

We also try to protect the confidential nature of our proprietary information by using commonly accepted information technology systems and network security measures. Such measures may not provide adequate protection for our proprietary information. For example, our internal procedures may not prevent an existing or former employee or consultant from misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not provide an adequate remedy to fully protect our interests.

While we maintain insurance policies that may cover certain liabilities in connection with a cybersecurity incident, we cannot be certain that our insurance coverage will be adequate for liabilities actually incurred, that insurance will continue to be available to us on commercially reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim.

We are implementing a new enterprise resource planning system. Our failure to implement it successfully, on time and on budget could have a material adverse effect on us.

We are implementing a new enterprise resource planning (“ERP”) system and expect the implementation of new systems across our various entities to take longer than initially expected, which may cause us to incur additional costs. Notwithstanding the above, we continue to rely on our existing enterprise resource planning system and have not experienced any disruptions to our business, operations and financial reporting.

ERP implementations are complex, time-consuming, labor intensive, and involve substantial expenditures on system software and implementation activities. The ERP system is critical to our ability to provide important information to our management, obtain and deliver products, provide services and customer support, send invoices and track payments, fulfill contractual obligations, accurately maintain books and records, provide accurate, timely and reliable reports on our financial and operating results, and otherwise operate our business. ERP implementations also require transformation of business and financial processes in order to reap the benefits of the ERP system. Any such implementation involves risks inherent in the conversion to a new computer system, including loss of information and potential disruption to our normal operations. The implementation and maintenance of the new ERP system has required, and will continue to require, the investment of significant financial and human resources and the implementation may be subject to additional delays or cost overruns. In addition, we may not be able to successfully complete the implementation of the new ERP system without experiencing difficulties.

Any disruptions, delays or deficiencies in the design and implementation or the ongoing maintenance of the new ERP system could adversely affect our ability to process orders, ship products, provide services and customer support, send invoices and track payments, fulfill contractual obligations, accurately maintain books and records, provide accurate, timely and reliable reports on our financial and operating results, including reports required by the SEC such as the evaluation of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, and otherwise operate our business. Additionally, if we do not effectively implement the ERP system as planned or the system does not operate as intended, the effectiveness of our internal control over financial reporting could be adversely affected or our ability to assess it adequately could be delayed.

Currency and Tax Risks

We are exposed to fluctuations in currency exchange rates that could negatively impact our financial results and cash flows.

Because most of our foreign sales are denominated in U.S. dollar, an increase in value of the U.S. dollar against foreign currencies will make our products more expensive than those offered by some of our foreign competitors. In addition, a weakening of the U.S. dollar against other currencies could make our costs in certain non-U.S. locations more expensive to fund. Our ability to compete overseas may therefore be materially and adversely affected by the fluctuations of the U.S. dollar against other currencies.

Because nearly all of our business is conducted outside the U.S., we face exposure to adverse movements in foreign currency exchange rates which could have a material adverse impact on our financial results and cash flows. Historically, our primary exposures have related to net working capital exposures denominated in currencies other than the foreign subsidiaries’ functional currency, and remeasurement of our foreign subsidiaries’ net monetary assets from the subsidiaries’ local currency into the subsidiaries’ functional currency. In general, an increase in the value of the U.S. dollar could require certain of our foreign subsidiaries to record translation and remeasurement gains. Conversely, a decrease in the value of the U.S. dollar could require certain of our foreign subsidiaries to record losses on translation and remeasurement. An increase in the value of the U.S. dollar could increase the cost to our customers of our products in those markets outside the U.S. where we sell in U.S. dollars, and a weakened U.S. dollar could increase the cost of local operating expenses and procurement of raw materials, both of which could have an adverse effect on our cash flows. Our primary exposures include the Singapore Dollar, Chinese Yuan, Japanese Yen, Swiss Franc, Philippine Peso, Thai Baht, New Taiwan Dollar, South Korean Won, New Israeli Shekel, Malaysian Ringgit and Euro. Although we have entered into foreign exchange forward contracts from time to time to hedge our operating expenses against certain foreign currency exposure, our attempts to hedge against these risks may not be successful and may result in a material adverse impact on our financial results and cash flows.

Changes in tax legislation could adversely impact our future profitability.

We are subject to income taxes in the U.S. and many foreign jurisdictions. Tax laws and regulations are continuously evolving with corporate tax reform, base-erosion efforts, global minimum tax, and increased transparency continuing to be high priorities in many tax jurisdictions in which we operate. Although the timing and methods of implementation may vary, many countries, including those in the Asia/Pacific region in which we have significant operations, have implemented, or are in the process of implementing, legislation or practices inspired by the base erosion and profit shifting project undertaken by the Organization for Economic Co-operation and Development (“OECD”), for example, Pillar Two. While Pillar Two did not have a material tax impact in fiscal 2025, we will continue to monitor new tax legislation and other developments since changes in tax legislation, or in the interpretation of existing legislation, could materially and adversely affect our financial condition and operating results.

On July 4, 2025, the One Big Beautiful Bill Act (the "OBBBA") was enacted, introducing amendments to U.S. tax laws, including expensing of domestic research and development costs, a limitation on business interest expense, and other tax changes, with effective dates beginning in tax year 2025 (the Company's fiscal year 2026). The Company is still evaluating the impact the tax law changes will have on its future consolidated financial statements. These legislative changes could materially and adversely affect our financial condition and operating results in future periods.

Other changes in taxation could materially impact our future effective tax rate.

Additionally, our future effective tax rate could be affected by numerous other factors including higher or lower than anticipated foreign earnings in various jurisdictions where we are subjected to tax rates that differ from the U.S. federal statutory tax rate, by changes in the valuation allowances recorded against certain deferred tax balances, or by changes in accounting principles and reporting requirements, or including the interpretations and application of such accounting principles and reporting requirements. Changes in our assertion for foreign earnings, whether permanently or non-permanently reinvested, as a result of changes in facts and circumstances or challenges by tax authorities to our historic or future tax positions and transfer pricing policies, could also significantly adversely impact our future effective tax rate.

Risks Related to Our Shares and Corporate Law

We have the ability to issue additional equity securities, which would lead to dilution of our issued and outstanding common stock.

We may from time to time issue additional equity securities or securities convertible into equity securities, which would result in dilution of our existing shareholders’ equity interests in us. Our board of directors has the authority to issue, without vote or action of shareholders, preferred shares in one or more series, and has the ability to fix the rights, preferences, privileges and restrictions of any such series. Any such series of preferred shares could contain dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences or other rights superior to the rights of holders of our common stock. In addition, we are authorized to issue, without shareholder approval, up to an aggregate of 200 million common stock, of which approximately 51.9 million shares were outstanding as of October 4, 2025. We are also authorized to issue, without shareholder approval (except as required by the rules of the Nasdaq stock market), securities convertible into either common stock or preferred stock. We may issue such shares in connection with financing transactions, joint ventures, mergers and acquisitions or other purposes. In addition, our shareholders will experience additional dilution when performance or restricted share units vest and settle, when we issue equity awards to our employees under our equity incentive plans, or when we otherwise issue additional equity.

Anti-takeover provisions in our articles of incorporation and bylaws and under Pennsylvania law may discourage other companies from attempting to acquire us.

Some provisions of our articles of incorporation and bylaws as well as Pennsylvania law may discourage some transactions where we would otherwise experience a fundamental change. For example, our articles of incorporation and bylaws contain provisions that:

•permit our board to issue “blank check” preferred shares without shareholder approval; and

•prohibit us from engaging in some types of business combinations with a holder of 20% or more of our voting securities without super-majority board or shareholder approval.

On June 5, 2025, the Board approved an amendment and restatement of our bylaws to declassify the Board and provide for the annual election of all directors, phased in over a four-year period. As a result, at the 2029 annual meeting of shareholders and each annual meeting of shareholders thereafter, all directors will be elected for a one-year term expiring at the next annual meeting of shareholders. Until such time when the above declassification is complete, shareholders may remove directors only for cause. These provisions and some other provisions of the Pennsylvania Business Corporation Law could delay, defer or prevent us from experiencing a fundamental change and may adversely affect our common shareholders' voting and other rights.

If our internal controls over financial reportingor our disclosure controls and procedures are not effective, we may not be able to accurately report our financial results or file our periodic reports in a timely manner, which may cause investors to lose confidence in our reported financial information and may lead to a decline in the trading price of our common stock.

As a public company, we are required to maintain internal control over financial reporting and disclosure controls and procedures. Section 404 of the Sarbanes-Oxley Act requires that we evaluate and determine the effectiveness of our internal control over financial reporting and provide a management report on our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. If we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to certify that our internal control over financial reporting is effective, our consolidated financial statements may contain material misstatements and we could be required to revise or restate our financial results. This could materially and adversely affect our business, results of operations and financial condition, restrict our ability to access the capital markets, require us to expend significant resources to correct the material weakness, subject us to fines, penalties or judgments, harm our reputation, adversely affect the trading price of our common stock, or otherwise cause a decline in investor confidence.

Item 1C. CYBERSECURITY

Cybersecurity Risk Management and Strategy

We rely on information systems and the data stored on them to conduct our operations. We have adopted and maintain a cybersecurity risk management program, as a subset of our broader enterprise risk management program, which is designed in accordance with our risk profile and business. Our cybersecurity practices are aligned with standard industry frameworks such as the National Institute of Standards and Technology (NIST) Cybersecurity Framework, International Organization for Standardization (ISO) 27001, Center for Internet Security Critical Security Controls and other industry standards.

Our cybersecurity risk management program incorporates multiple components, including, but not limited to, policies, guidelines, procedures, infrastructure, and systems that are designed to protect the confidentiality, integrity and availability of our critical systems and information.

Elements of our cybersecurity risk management process include, but are not limited to, the following:

•Annual cybersecurity risk assessments of critical infrastructure and systems;

•Annual vulnerability scans and penetration testing;

•Mandatory, bi-annual cybersecurity awareness training for all employees, including phishing exercises; and

•An overarching written information security policy and written cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents.

We leverage IT service providers to perform penetration testing and support our cybersecurity awareness training program. We oversee cybersecurity risks related to third-party IT cloud service providers who have access to our systems and data. We require certain IT cloud service providers to complete cloud-based cybersecurity assessments.

We have not identified any cybersecurity incidents or threats that have materially affected us or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition. However, like other companies in our industry, we and our third-party vendors have from time to time experienced cybersecurity threats and other security incidents that have affected our information or systems. We have experienced, and expect to continue to be subject to, cybersecurity threats and incidents, ranging from employee error or misuse to individual attempts to gain unauthorized access to information systems, to sophisticated and targeted measures known as advanced persistent threats, none of which have been material to the Company to date.

For additional information on certain risks associated with cybersecurity, including with respect to prior cybersecurity incidents, please refer to “We may be subject to disruptions or failures in our information technology systems and network infrastructures that could have a material adverse effect on us” in Item 1A: Risk Factors.

Cybersecurity Governance

Our Board of Directors (the “Board”) has delegated responsibility for enterprise risk management, including cybersecurity risk oversight, to our Audit Committee (the “Committee”). The Committee receives quarterly information security updates from our Chief Financial Officer and Senior Director of Governance & Information Security (the “Senior Director, GIS”). The Committee in turn reports to the full Board regarding its activities, including those related to cybersecurity, on at least a bi-annual basis.

The Senior Director, GIS, who has been a head of information security for close to 15 years and has more than 27 years of overall experience in IT and cyber security industry, holds a Bachelor of Science in Information Technology from Bina Nusantara University and Master of Business Administration from University of Liverpool.

He receives support from our operational team which comprises cybersecurity, IT, controllership, and legal professionals who regularly review cybersecurity matters and evaluate emerging threats, as well as act as first responders to triage any cybersecurity incidents. In the event of a cybersecurity incident, the Committee and Board receive updates from this team on an ad-hoc basis, if appropriate, under our tiered escalation support framework.

PART II

Item 5.MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock is traded on The Nasdaq Global Market (“Nasdaq”) under the symbol “KLIC.” Based on data provided by The Depository Trust Company, on November 17, 2025, the management believes that there were approximately 389 holders of record of the shares of outstanding common stock, as defined by Rule 12g5-1 of the Exchange Act.

On each of August 29, 2025, June 5, 2025, March 6, 2025 and November 13, 2024, the Board of Directors declared a quarterly dividend of $0.205 per share of common stock, resulting in an aggregate dividend of $0.82 per share of common stock for the fiscal year ended October 4, 2025. The declaration of any future cash dividend is at the discretion of the Board of Directors, subject to applicable laws, and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that such dividends are in the best interests of the Company’s stockholders.

For the purpose of calculating the aggregate market value of shares of our common stock held by non-affiliates, as shown on the cover page of this Annual Report, we have assumed all of our outstanding shares were held by non-affiliates except for shares held by our directors and executive officers. However, this does not necessarily mean that all directors and executive officers of the Company are, in fact, affiliates of the Company, or there are no other persons who may be deemed to be affiliates of the Company. Further information concerning the beneficial ownership of our executive officers, directors and principal shareholders will be included in our Proxy Statement for the 2026 Annual Meeting of Shareholders to be filed with the Securities and Exchange Commission.

The following table summarizes the repurchases of common stock during the three months ended October 4, 2025 (in thousands, except per share amounts):

(1)On August 15, 2017, the Company’s Board of Directors authorized the Prior Program, as amended from time to time. Additionally, and as previously announced on November 13, 2024, the Board of Directors authorized the New Program, with the intention that the New Program initiate upon the completion of the Prior Program. Contemporaneously, on December 2, 2024, the Company entered into a new written trading plan under Rule 10b5-1 of the Exchange Act, to facilitate repurchases under the New Program. The plan permits the purchase of up to approximately $300 million of the Company’s common stock from December 2, 2024 through December 2, 2029. The New Program may be suspended or discontinued at any time and is funded using the Company’s available cash, cash equivalents and short-term investments. Under the New Program, shares may be repurchased through open market and/or privately negotiated transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under the New Program depend on market conditions as well as corporate and regulatory considerations.

•Critical Accounting Policies and Estimates

•Recent Accounting Pronouncements

•Results of Operations

•Liquidity and Capital Resources

•Other Obligations and Contingent Payments

Overview

For an overview of our business, please see “Part I, Item 1 — Business”.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements requires us to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. On an ongoing basis, we evaluate estimates, including, but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory, carrying value and lives of fixed assets, goodwill and intangible assets, income taxes, equity-based compensation expense and warranties. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable. As a result, we make judgments regarding the carrying values of our assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, we evaluate these estimates. Actual results may differ from these estimates.

We believe the following critical accounting policies, which have been reviewed with the Audit Committee of our Board of Directors, reflect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

In accordance with ASC No. 606, Revenue from Contracts with Customers, the Company recognizes revenue when we satisfy performance obligations as evidenced by the transfer of control of our products or services to customers. In general, the Company generates revenue from product sales, either directly to customers or to distributors. In determining whether a contract exists, we evaluate the terms of the agreement, the relationship with the customer or distributor and their ability to pay.

The Company recognizes revenue from sales of our products, including sales to our distributors, at a point in time, generally upon shipment or delivery to the customer or distributor, depending upon the terms of the sales order. Control is considered transferred when title and risk of loss pass, when the customer becomes obligated to pay and, where applicable, when the customer has accepted the products or upon expiration of the acceptance period. For sales to distributors, payment is due on our standard commercial terms and is not contingent upon resale of the products.

Table of Contents

Our business is subject to contingencies related to customer orders, including:

•Right of Return: A large portion of our revenue comes from the sale of equipment used in the semiconductor assembly process. Other product sales relate to consumable products, which are sold in high-volume quantities, and are generally maintained at low stock levels at the customer’s facility. Customer returns have historically represented a very small percentage of customer sales on an annual basis.

•Warranties: Our equipment is generally shipped with a one-year warranty against manufacturing defects. We establish reserves for estimated warranty expense when revenue for the related equipment is recognized. The reserve for estimated warranty expense is based upon historical experience and management’s estimate of future expenses, including product parts replacement, freight charges and labor costs expected to be incurred to correct product failures during the warranty period.

•Conditions of Acceptance: Sales of our consumable products generally do not have customer acceptance terms. In certain cases, sales of our equipment have customer acceptance clauses which may require the equipment to perform in accordance with customer specifications or when installed at the customer’s facility. In such cases, if the terms of acceptance are satisfied at our facility prior to shipment, the revenue for the equipment will be recognized upon shipment. If the terms of acceptance are satisfied at our customers’ facilities, the revenue for the equipment will not be recognized until acceptance, which is typically obtained after installation and testing, is received from the customer.

Service revenue is generally recognized over time as the services are performed.

The Company measures revenue based on the amount of consideration we expect to be entitled to in exchange for products or services. Any variable consideration such as sales incentives are recognized as a reduction of net revenue at the time of revenue recognition.

The Company’s performance obligations relate to contracts with a duration of less than one year, therefore as allowed under ASC 606, we have opted not to disclose the unsatisfied performance obligations for contracts with original expected durations of less than one year.

The length of time between invoicing and payment is not significant under our payment terms. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. Shipping and handling costs billed to customers are recognized in net revenue.

Shipping and handling costs paid by the Company are included in cost of sales.

Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from our customers’ failure to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. We are subject to concentrations of customers and sales to a few geographic locations, which could also impact the collectability of certain receivables. If global or regional economic conditions deteriorate or political conditions were to change in some of the countries where we do business, it could have a significant impact on our results of operations, and our ability to realize the full value of our accounts receivable.

Inventories

Inventories are stated at the lower of cost (on a first-in, first-out basis) or net realizable value. We generally provide reserves for obsolete inventory and for inventory considered to be in excess of demand. Demand is generally defined as 18 months forecasted future consumption for equipment, 24 months forecasted future consumption for spare parts, and 12 months forecasted future consumption for tools. Forecasted consumption is based upon internal projections, historical sales volumes, customer order activity and a review of consumable inventory levels at customers’ facilities. We communicate forecasts of our future consumption to our suppliers and adjust commitments to those suppliers accordingly. If required, we reserve the difference between the carrying value of our inventory and the lower of cost or net realizable value, based upon projections about future consumption, and market conditions. If actual market conditions are less favorable than projections, additional inventory reserves may be required.

Table of Contents

Inventory reserve provision for certain subsidiaries is determined based on management’s estimate of future consumption for equipment and spare parts. This estimate is based on historical sales volumes, internal projections and market developments and trends.

Accounting for Impairment of Goodwill

ASC No. 350, Intangibles-Goodwill and Other requires goodwill and other intangible assets with indefinite lives to be reviewed for impairment annually, or more frequently if circumstances indicate a possible impairment. We assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, a company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the impairment test is unnecessary. However, if a company concludes otherwise, then it is required to perform the goodwill impairment test. The Company’s impairment test is performed by comparing the fair value of a reporting unit with its carrying value, and determining if the carrying amount exceeds its fair value.

As part of the annual evaluation, the Company performs an impairment test of its goodwill in the fourth quarter of each fiscal year to coincide with the completion of its annual forecasting and refreshing of its business outlook processes. On an ongoing basis, the Company monitors if a “triggering” event has occurred that may have the effect of reducing the fair value of a reporting unit below its respective carrying value. Adverse changes in expected operating results and/or unfavorable changes in other economic factors used to estimate fair values could result in a non-cash impairment charge in the future.

Impairment assessments inherently involve judgment as to the assumptions made about the expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact the assumptions as to prices, costs, growth rates or other factors that may result in changes in the estimates of future cash flows. Although the Company believes the assumptions that it has used in testing for impairment are reasonable, significant changes in any one of the assumptions could produce a significantly different result. Indicators of potential impairment, including significant and unforeseen customer losses, a significant adverse change in legal factors or in the business climate, a significant adverse action or assessment by a regulator, a significant stock price decline or unanticipated competition, may lead the Company to perform interim goodwill impairment assessments.

The Company performed its annual impairment test in the fourth quarter of fiscal 2025 and elected to perform the quantitative impairment test as permitted by ASC 350 for another reporting unit within the "All Others" category and the qualitative impairment assessment for all of its remaining reporting units. Based on the quantitative and qualitative assessments performed, the Company concluded other than the impairment taken on one reporting unit within the APS reportable segment and one reporting unit within the "All Others" category in relation to the cessation of EA Equipment Business, no impairment on the Company's other recorded goodwill was required. The persistent macroeconomic headwinds could, in the future, require changes to assumptions utilized in the determination of the estimated fair values of the reporting units which could result in future goodwill impairment charges. Net sales and earnings growth rates could be negatively impacted by reductions or changes in demand for our products. The discount rate utilized in our valuation model could also be impacted by changes in the underlying interest rates and risk premiums included in the determination of the cost of capital. For further information on goodwill and other intangible assets, see "Note 3: Goodwill and Intangible Assets” in the notes to our consolidated financial statements in “Part II, Item 8 — Financial Statements and Supplementary Data”.

Income Taxes

In accordance with ASC No. 740, Income Taxes, deferred income taxes are determined using the balance sheet method. The Company records a valuation allowance to reduce its deferred tax assets to the amount expected, on a more likely than not basis, to be realized. While the Company has considered future taxable income and ongoing tax planning strategies in assessing the need for the valuation allowance, if it were to determine that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase income in the period when such determination is made. Likewise, should the Company determine that it would not be able to realize all or part of its deferred tax assets in the future, an adjustment to deferred tax assets would decrease income in the period when such determination is made.

Table of Contents

The Company determines the amount of unrecognized tax benefit with respect to uncertain tax positions taken or expected to be taken on its income tax returns in accordance with ASC No. 740 Topic 10, Income Taxes, General (“ASC 740.10”). Under ASC 740.10, the Company utilizes a two-step approach for evaluating uncertain tax positions. Step one, or recognition, requires a company to determine if the weight of available evidence indicates a tax position is more likely than not to be sustained upon examination solely based on its technical merit. Step two, or measurement, is based on the largest amount of benefit, which is more likely than not to be realized on settlement with the taxing authority, including resolution of related appeals or litigation processes, if any.

Equity-Based Compensation

The Company accounts for equity-based compensation under the provisions of ASC No. 718, Compensation - Stock Compensation (“ASC 718”). ASC 718 requires the recognition of the fair value of the equity-based compensation in net income. Compensation expense associated with Relative TSR Performance Share Units is determined using a Monte-Carlo valuation model, and compensation expense associated with time-based and Growth Performance Share Units is determined based on the number of shares granted and the fair value on the date of grant. See "Note 11: Shareholders’ Equity and Employee Benefit Plans” in the notes to our consolidated financial statements in “Part II, Item 8 — Financial Statements and Supplementary Data” for a summary of the terms of these performance-based awards. The fair value of equity-based awards is amortized over the vesting period of the award and the Company elected to use the straight-line method for awards granted after the adoption of ASC 718.

Bookings and Backlog

Our backlog consists of customer orders scheduled for shipment within the next twelve months. A booking is recorded when a customer order is reviewed and it is determined that all specifications can be met, production (or service) can be scheduled, a delivery date can be set, and the customer meets our credit requirements. We use bookings to evaluate the results of our operations, generate future operating plans and assess the performance of our Company. While we believe that this measure is useful in evaluating our business, this information should be considered as supplemental in nature and is not meant as a substitute for revenue recognized in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate bookings differently or not at all, which reduces its usefulness as a comparative measure. Reconciliation of bookings to net revenue is not practicable. A majority of our orders are subject to cancellation or deferral by our customers with limited or no penalties. Also, customer demand for our products can vary dramatically without prior notice. Because of the volatility of customer demand, possibility of customer changes in delivery schedules or cancellations and potential delays in product shipments, our backlog as of any particular date may not be indicative of net revenue for any succeeding period.

The following tables reflect the bookings and backlog for fiscal 2025 and 2024:

Fiscal

As of

The semiconductor industry is volatile and our operating results are adversely impacted by volatile worldwide economic conditions. Though the semiconductor industry’s cycle can be independent of the general economy, global economic conditions may have a direct impact on demand for semiconductor units and ultimately demand for semiconductor capital equipment and expendable tools. Accordingly, our business and financial performance is impacted, both positively and negatively, by fluctuations in the macroeconomic environment. Our visibility into future demand is generally limited and forecasting is difficult. There can be no assurances regarding levels of demand for our products and we believe historical industry-wide volatility will persist.

The U.S. and several other countries have levied tariffs on certain goods. In particular, trade tensions between the U.S. and China have been escalating since 2018, with U.S. tariffs on Chinese goods and retaliatory Chinese tariffs on U.S. goods. These have resulted in uncertainties in the semiconductor, LED, memory and automotive markets. While the Company anticipates long-term growth in semiconductor consumption, we observed trade-related adverse impacts in demand from China, which continues to persist in fiscal 2025 and beyond.

Net Revenue

Our net revenues for fiscal 2025 decreased as compared to our net revenues for fiscal 2024. The decrease in net revenue is primarily due to lower volume in Ball Bonding Equipment, APS and All Others, partially offset by the higher volumes in Wedge Bonding Equipment and Advanced Solutions as further outlined in the tables presented immediately below.

The following table reflects the net revenue by reportable segment for fiscal 2025 and 2024:

Fiscal

(dollar amounts in thousands) 2025 2024 $ Change % Change

Net Revenue % of total net revenue Net Revenue % of total net revenue

Ball Bonding Equipment

For fiscal 2025, the decrease in Ball Bonding Equipment net revenue as compared to fiscal 2024 was primarily due to a lower volume of customer purchases in the general semiconductor and memory end markets as a result of relatively stable factory utilization levels in certain regions and a decrease in customer investments as a result of uncertainties in the overall macroeconomic environment.

Wedge Bonding Equipment

For fiscal 2025, the increase in Wedge Bonding Equipment net revenue as compared to fiscal 2024 was primarily due to a higher volume of customer purchases primarily in the general semiconductor and partially offset by lower customer purchases in the automotive markets.

Advanced Solutions

For fiscal 2025, the increase in Advanced Solutions net revenue as compared to fiscal 2024 was primarily due to a higher volume of customer purchases in LED which is included in the industrial end market and higher customer purchases in the general semiconductor end market.

APS

For fiscal 2025, the decrease in APS net revenue as compared to fiscal 2024 was primarily due to a lower volume of customer purchases primarily in spares and services, and unfavorable pricing from bonding tools.

All Others

For fiscal 2025, the decrease in net revenue in the “All Others” category as compared to fiscal 2024 was primarily due to a lower volume of customer purchases in the general semiconductor end market.

Gross Profit Margin

The following table reflects the gross profit as a percentage of net revenue by reportable segment for fiscal 2025 and 2024:

Fiscal Basis Point

Ball Bonding Equipment

For fiscal 2025, the higher Ball Bonding Equipment gross profit margin as compared to fiscal 2024 was primarily driven by a favorable product mix, including lower sales of lower margin products and a shift in customer mix, including higher sales to customers where we achieve higher average margins.

Wedge Bonding Equipment

For fiscal 2025, the lower Wedge Bonding Equipment gross profit margin as compared to fiscal 2024 was primarily driven by a less favorable product mix, including higher sales of lower margin products and a shift in customer mix, including higher sales to customers where we achieve lower average margins.

Advanced Solutions

For fiscal 2025, the higher Advanced Solutions gross profit margin as compared to fiscal 2024 was primarily driven by the inventory write-down charges in the prior year as a result of the cancellation of Project W and favorable product mix, including higher sales of higher margin products.

APS

For fiscal 2025, the lower APS gross profit margin as compared to fiscal 2024 was primarily driven by the spares related inventory write-down charges incurred as a result of the cessation of the EA equipment business, lower volume from spares and services, and unfavorable pricing from bonding tools.

All Others

For fiscal 2025, the lower All Others gross profit margin as compared to fiscal 2024 was primarily driven by the inventory write-down charges incurred as a result of the cessation of the EA equipment business.

Gain relating to cessation of business (75,987) — (75,987) N/A

Selling, General and Administrative (“SG&A”)

For fiscal 2025, the higher SG&A expenses as compared to fiscal 2024 was primarily due to $7.8 million higher severance expenses and $3.1 million higher staff costs. This was partially offset by $6.2 million net favorable variance in foreign exchange, $1.6 million lower professional services and $1.2 million lower miscellaneous expenses.

Research and Development (“R&D”)

For fiscal 2025, the lower R&D expenses as compared to fiscal 2024 was primarily due to $4.5 million lower prototype materials. This was partially offset by $2.8 million higher staff costs.

Gain relating to cessation of business

For fiscal 2025, the gain relating to cessation of business as compared to fiscal 2024 was primarily due to the $71.1 million reimbursement for certain costs and expenses from Project W cancellation, a $3.2 million gain on the disposal of a subsidiary and a $1.7 million gain from the supplier settlement.

ImpairmentCharges

For fiscal 2025, the impairment charges were due to $39.9 million impairment charges on long-lived assets, intangible assets and goodwill related to the cessation of the EA equipment business. The impairment charges in fiscal 2024 were due to $44.5 million impairment charges on long-lived assets related to the cancellation of Project W.

Loss from Operations

The changes in income/loss from operations for the respective segments are due to the changes in net revenue, gross profit margin and operating expenses as explained in the respective sections above.

Changes in cash and cash equivalents $ (11,439) $ (302,255)

Cash and cash equivalents, beginning of period 227,147 529,402

Fiscal 2025

The net cash provided by operating activities was primarily due to non-cash adjustments to net income of $121.9 million and a net income of $0.2 million, partially offset by a net unfavourable change in operating assets and liabilities of $8.6 million. The non-cash adjustments were primarily due to impairment charges of $39.8 million and an inventory write-down of $31.5 million as a result of the cessation of the EA equipment business. The net change in operating assets and liabilities was primarily driven by an increase in inventories of $26.1 million after excluding the impact of the inventory write-down of $31.5 million, a decrease in income tax payable of $14.2 million and an increase in prepaid expenses and other current assets of $2.3 million. This was partially offset by a decrease in accounts and other receivable of $10.1 million and a net increase in accounts payable, accrued expenses and other liabilities of $24.1 million.

The increase in inventories was due to the buildup of long lead time materials to fulfill certain customer purchase orders. The decrease in income tax payable was primarily due to the current year payment of the U.S. one-time transition tax. The increase in prepaid expenses and other current assets was mainly due to higher prepayments to suppliers. The decrease in accounts and other receivable was mainly due to lower sales for the year. The net increase in accounts payable, accrued expenses and other liabilities was primarily due to higher accrued employee termination benefits and adverse purchase commitments.

Net cash provided by investing activities was due to net maturity of short-term investments of $55.0 million and net cash received from the disposal of a subsidiary of $2.5 million, partially offset by capital expenditures of $17.2 million, investment in debt securities of $10.0 million and investment in a private equity fund of $2.9 million.

Net cash used in financing activities was primarily due to common stock repurchases of $97.1 million and dividend payments of $54.1 million.

Fiscal 2024

Net cash provided by operating activities consisted of net loss of $69.0 million, non-cash adjustments of $179.3 million and a net unfavourable change in operating assets and liabilities of $79.2 million. The non-cash adjustments were primarily due to impairment charges of $44.5 million and inventory write-down of $57.3 million as a result of the cancellation of the Project. The net change in operating assets and liabilities was primarily driven by an increase in accounts and notes receivable of $34.7 million, an increase in inventories of $31.5 million, and a decrease in income tax payable of $17.7 million. This was partially offset by a decrease in prepaid expenses and other current assets of $9.1 million.

The increase in accounts and other receivable was primarily due to the timing of payments due. The increase in inventories was due to the buildup of long lead time materials to fulfill certain customer purchase orders. The decrease in income tax payable is primarily due to the current year payment of the U.S. one-time transition tax and tax benefit from the U.S. Tax Court opinion in Varian Medical Systems, Inc. v. Commissioner. The decrease in prepaid expenses was mainly due the transfer of contract assets to net account receivables.

The net cash used in investing activities was due to net purchase of short-term investments of $120.0 million, capital expenditures of $16.1 million and investment in a private equity fund of $2.4 million.

The net cash used in financing activities was primarily due to common stock repurchases of $150.8 million and dividend payments of $44.2 million.

Fiscal 2026 Liquidity and Capital Resource Outlook

We expect our fiscal 2026 capital expenditures to be between $8.0 million and $12.0 million. The actual amounts for fiscal 2026 will vary depending on market conditions. Expenditures are anticipated to be primarily used for research and development projects, enhancements to our manufacturing operations, improvements to our information technology security, ongoing implementation of our enterprise resource planning system and leasehold improvements for our facilities. Our ability to make these expenditures will depend, in part, on our future cash flows, which are determined by our future operating performance and, therefore, subject to prevailing macroeconomic conditions, trade tensions, inflationary pressures, geopolitical tensions, including the ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict, and other factors, some of which are beyond our control.

As of October 4, 2025 and September 28, 2024, approximately $414.3 million and $302.6 million of cash, cash equivalents, and short-term investments were held by the Company’s foreign subsidiaries, respectively, with a large portion of the cash amounts expected to be available for use in the U.S. without incurring additional U.S. income tax.

The Company’s operations and capital requirements are funded primarily by cash on hand and cash generated by foreign operating activities. We believe these sources of cash and liquidity are sufficient to meet our additional liquidity needs for the foreseeable future, including payment of dividends, share repurchases and income taxes.

We believe that our existing cash, cash equivalents, short-term investments and anticipated cash flows from operations will be sufficient to meet our liquidity and capital requirements, notwithstanding the macroeconomic headwinds, for the next twelve months and beyond. Our liquidity is affected by many factors, some based on normal operations of our business and others related to macroeconomic conditions including inflationary pressures, industry-related uncertainties, and effects arising from the ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict, which we cannot predict. We also cannot predict economic conditions and industry downturns or the timing, strength or duration of recoveries. We intend to continue to use our cash for working capital needs and for general corporate purposes.

In this unprecedented macroeconomic environment, and as a result of the ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict or for other reasons, we may seek, as we believe appropriate, additional debt or equity financing which would provide capital for corporate purposes, working capital funding, additional liquidity needs or to fund future growth opportunities, including possible acquisitions. The timing and amount of potential capital requirements cannot be determined at this time and will depend on a number of factors, including our actual and projected demand for our products, semiconductor and semiconductor capital equipment industry conditions, competitive factors, the condition of financial markets and the global economic situation.

Share Repurchase Program

On August 15, 2017, the Company’s Board of Directors authorized a program to repurchase up to $100 million of the Company’s common stock on or before August 1, 2020. In 2018, 2019, 2020 and 2022, the Board of Directors increased the share repurchase authorization to $200 million,$300 million, $400 million and $800 million, respectively, and extended its duration through August 1, 2025 (the "Prior Program").

During the three months ended December 28, 2024, the Company repurchased a total of approximately 657.0 thousand shares of common stock under the Prior Program at a cost of approximately $30.3 million. On December 2, 2024, the Company announced that it had completed share repurchases under the Prior Program.

Additionally, as announced on November 13, 2024, the Board of Directors authorized a new share repurchase program to repurchase up to $300 million of the Company's common stock (the "New Program"). On December 2, 2024, the Company entered into a new written trading plan under Rule 10b5-1 of the Exchange Act, to facilitate repurchases under the New Program. The plan permits the purchase of up to approximately $300 million of the Company’s common stock from December 2, 2024 through December 2, 2029. The New Program may be suspended or discontinued at any time and is funded using the Company’s available cash, cash equivalents and short-term investments. Under the New Program, shares may be repurchased through open market and/or privately negotiated transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under the New Program depend on market conditions as well as corporate and regulatory considerations.

During the fiscal year ended October 4, 2025, the Company repurchased a total of approximately 1,785.0 thousand shares of common stock under the New Program at a cost of approximately $66.2 million.

Table of Contents

The stock repurchases were recorded in the periods the repurchased shares were delivered and accounted for as treasury stock in the Company’s Consolidated Balance Sheets. The Company records treasury stock purchases under the cost method using the first-in, first-out (FIFO) method. Upon re-issuance of treasury stock, amounts in excess of the acquisition cost are credited to additional paid-in capital.

If the Company reissues treasury stock at an amount below its acquisition cost and additional paid-in capital associated with prior treasury stock transactions is insufficient to cover the difference between acquisition cost and the reissue price, this difference is recorded against retained earnings.

As of October 4, 2025, our remaining stock repurchase authorization under the New Program was approximately $233.8 million.

Dividends

On August 29, 2025, June 5, 2025, March 6, 2025 and November 13, 2024, the Board of Directors declared a quarterly dividend of $0.205 per share of common stock, resulting in an aggregate dividend of $0.82 per share of common stock for the fiscal year ended October 4, 2025. The declaration of any future cash dividend is at the discretion of the Board of Directors and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that such dividends are in the best interests of the Company’s stockholders.

Other Obligations and Contingent Payments

In accordance with U.S. generally accepted accounting principles, certain obligations and commitments as of October 4, 2025 are appropriately not included in the Consolidated Balance Sheets and Statements of Operations in this Form 10-K. However, because these obligations and commitments are entered into in the normal course of business and because they may have a material impact on our liquidity, we have disclosed them in the table below.

Additionally, as of October 4, 2025, the Company had deferred tax liabilities of $35.5 million and unrecognized tax benefit recorded within the income tax payable for uncertain tax positions of $18.4 million, including related accrued interest of $3.1 million. These amounts are not included in the contractual obligation table below because we are unable to reasonably estimate the timing of these payments at this time.

The following table presents certain payments due by the Company under contractual obligations with minimum firm commitments as of October 4, 2025:

Credit Facilities

On February 15, 2019, the Company entered into a Facility Letter and Overdraft Agreement (collectively, the “Facility Agreements”) with MUFG Bank, Ltd., Singapore Branch (the “Bank”). The Facility Agreements provide the Company and one of its subsidiaries with an overdraft facility of up to $150.0 million (the “Overdraft Facility”) for general corporate purposes.

On June 6, 2025, the Company terminated the Facility Agreements with the Bank. As of the date of termination, there were no outstanding amounts under the Overdraft Facility. In addition, the Company did not incur any early termination penalties in connection with the termination of the Facility Agreements.

As of October 4, 2025, other than the bank guarantee disclosed in "Note 10: Debt and Other Obligations” in the notes to our consolidated financial statements in “Part II, Item 8 — Financial Statements and Supplementary Data”, we did not have any other off-balance sheet arrangements, such as contingent interests or obligations associated with variable interest entities.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our available-for-sale securities, if applicable, may consist of short-term investments in highly rated debt instruments of the U.S. Government and its agencies, financial institutions, and corporations. We continually monitor our exposure to changes in interest rates and credit ratings of issuers with respect to any available-for-sale securities and target an average life to maturity of less than 18 months. Accordingly, we believe that the effects on us of changes in interest rates and credit ratings of issuers are limited and would not have a material impact on our financial condition or results of operations.

Foreign Currency Risk

Our international operations are exposed to changes in foreign currency exchange rates due to transactions denominated in currencies other than the location’s functional currency. Our international operations are also exposed to foreign currency fluctuations that impact the remeasurement of net monetary assets of those operations whose functional currency, the U.S. dollar, differs from their respective local currencies, most notably in Israel, Singapore and Switzerland. Our U.S. operations also have foreign currency exposure due to net monetary assets denominated in currencies other than the U.S. dollar. In addition to net monetary remeasurement, we have exposures related to the translation of subsidiary financial statements from their functional currency, the local currency, into its reporting currency, the U.S. dollar, most notably in the Netherlands, China, Taiwan, Japan and Germany.

Based on our foreign currency exposure as of October 4, 2025, a 10.0% fluctuation could impact our financial position, results of operations or cash flows by $6.0 million to $7.0 million. Our attempts to hedge against these risks may not be successful and may result in a material adverse impact on our financial results and cash flow.

We enter into foreign exchange forward contracts to hedge a portion of our forecasted foreign currency-denominated expenses in the normal course of business and, accordingly, they are not speculative in nature. These instruments generally mature within twelve months. We have foreign exchange forward contracts with a notional amount of $50.0 million outstanding as of October 4, 2025.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Kulicke and Soffa Industries, Inc. and its subsidiaries(the “Company”) as of October 4, 2025and September 28, 2024,and the related consolidated statements of operations, of comprehensive income, of changes in shareholders’ equity and of cash flowsfor each of the three years in the period ended October 4, 2025, including the related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended October 4, 2025 appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”).We also have audited the Company’s internal control over financial reporting as of October 4, 2025, based on criteria established in Internal Control - Integrated Framework(2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidatedfinancial statements referred to above present fairly, in all material respects, the financial position of the Company as of October 4, 2025 and September 28, 2024, and the results of itsoperations and itscash flows for each of the three years in the period ended October 4, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 4, 2025, based on criteria established in Internal Control - Integrated Framework(2013)issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidatedfinancial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidatedfinancial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidatedfinancial statements included performing procedures to assess the risks of material misstatement of the consolidatedfinancial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidatedfinancial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidatedfinancial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable

assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to theconsolidated financial statements; and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on theconsolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of inventories - Reserves for excess and obsolete raw materials

As described in Notes 1 and 2 to the consolidated financial statements, the Company’s consolidated net inventory balance was $160.2 million. The Company generally provides reserves for obsolete inventory and for inventory considered to be in excess of demand. Demand is generally defined as forecasted future consumption for inventories, and is based upon internal projections, historical sales volumes, customer order activity and a review of consumable inventory levels at customers’ facilities.

The principal considerations for our determination that performing procedures relating to the valuation of inventories, specifically the reserves for excess and obsolete raw materials, is a critical audit matter are our assessment that this is an area of significant judgment by management when developing reserves for excess and obsolete raw materials, including developing the assumptions related to forecasted future consumption for raw materials. This has in turn led to significant auditor judgment, subjectivity, and effort in performing procedures and evaluating the reasonableness of management’s significant assumptions related to the forecasted future consumption for raw materials.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s reserves for excess and obsolete raw materials, including controls over management’s assumptions related to forecasted future consumption for raw materials. These procedures also included, among others, testing management’s process for developing the reserves for excess or obsolete raw materials; evaluating the appropriateness of management’s approach; testing the completeness and accuracy of underlying data used in the approach; and evaluating the reasonableness of management’s assumptions related to forecasted future consumption for raw materials. Evaluating management’s assumptions related to forecasted future consumption for raw materials involved evaluating whether the assumptions used by management was reasonable considering (i) current and past sales results, (ii) the consistency of sales with external market and industry data, and (iii) comparing prior year estimates of sales to actual sales results in the current year.
