**<u>PART I</u>**

**Item 1. Business.**

**OUR COMPANY**

Entegris, Inc. ("Entegris", "the Company", "us", "we", or "our") is a leading supplier of critical advanced materials and process solutions for the semiconductor and other high-technology industries. We leverage our unique breadth of capabilities to provide customers with innovative, science-based solutions to their toughest technology challenges, helping improve productivity and product performance in the most advanced manufacturing environments.

Semiconductors, or integrated circuits, are key components in electronic devices that continue to transform how we live, communicate and work. Many products and emerging applications—including artificial intelligence ("AI"), high-performance and cloud computing, smartphones, wearable technology, electric and autonomous vehicles, the Internet of Things, gaming, virtual/augmented reality, and smart healthcare— are expected to drive long-term secular demand for semiconductor and require faster, more powerful, more compact and more energy efficient semiconductors. Industry forecasts project semiconductor sales reaching approximately $1.6 trillion by 2030, which we believe will create significant opportunities for our products.

As semiconductors move to smaller geometries and new device architectures, they require innovative materials and stringent purity standards throughout manufacturing. Entegris offers the industry's most comprehensive electronic materials portfolio, with core capabilities in materials science and materials purity, and complementary solutions that accelerate time to yield. We believe these capabilities are critical enablers of our customers' technology roadmaps. We expect these trends to create significant opportunities for our products, expand our served addressable market and increase Entegris' content per wafer, positioning us to outperform our markets over the long term.

Our business is organized and operated in two operating segments. These segments share common business systems and processes, technology centers and technology roadmaps.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Materials Solutions segment, or MS, provides materials-based solutions, such as chemical vapor and atomic layer deposition materials, chemical mechanical planarization ("CMP") slurries and pads, ion implantation specialty gases, formulated etch and clean materials, and other specialty materials that enable our customers to achieve better device performance and faster time to yield, while providing lower total cost of ownership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Advanced Purity Solutions segment, or APS, offers filtration, purification and contamination-control solutions that improve customers' yield, device reliability and cost by ensuring the purity of critical liquid chemistries and gases and the cleanliness of wafers and other substrates used throughout semiconductor manufacturing processes, the semiconductor ecosystem and other high-technology industries.

Our complementary capabilities enable co-optimized, integrated solutions that improve device performance, lower cost of ownership and accelerate time to market. We address complex manufacturing challenges across deposition, CMP and post-CMP modules with solutions including advanced deposition materials, CMP slurries, pads and post-CMP cleaning chemistries (each from our MS segment), and CMP slurry filters, high-purity packaging and fluid monitoring systems (each from our APS segment). As leading semiconductor manufacturers implement molybdenum into advanced nodes, Entegris is uniquely positioned to support this transition and to solve challenges associated with integrating a new material through our expertise and solutions in precursors, deposition, etch, CMP consumables and contamination control.

**ACQUISITIONS AND DIVESTITURES**

On February 10, 2023, the Company terminated a definitive agreement to sell its Pipeline and Industrial Materials ("PIM") business, which became part of the Company with the acquisition of CMC Materials, to Infineum USA L.P.

**THE SEMICONDUCTOR ECOSYSTEM**

Semiconductor manufacturing requires hundreds of complex, sensitive process steps in which a variety of materials are repeatedly applied to silicon wafers to build integrated circuits on the wafer surface. The areas of the semiconductor ecosystem that rely most heavily on our products and solutions are described below.

**<u>Photolithography</u>**. Photolithography is a process used to print complex circuit patterns onto wafers. The wafer is coated with a thin film of light-sensitive photoresist, exposed to light, and developed to create the pattern. Our products used throughout this process include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquid filtration, high-purity packaging and high-precision dispense systems that ensure pure, accurate and uniform distribution of contamination-free photoresists onto the wafer, enabling optimum yields; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gas microcontamination control solutions that eliminate airborne contaminants that can disrupt the photolithography processes.

**<u>Etch and Resist Strip</u>**. During the etch process, thin film areas are selectively removed from the wafer surface to create the desired circuit pattern. The hardened resist must then be removed and the etched area cleaned using high-purity chemicals. Our products used during and after etch include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Selective etch chemistries enabling high aspect ratio structures, including 3D-NAND and gate-all-around ("GAA") devices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Formulated cleaning solutions for photoresist and post-etch residue removal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Filters and purifiers that ensure purity of cleaning chemistries and achieve desired etch yields; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Precision-engineered coatings that protect equipment surfaces from corrosive chemistries and erosion while minimizing particle generation.

**<u>Deposition</u>**. During the deposition process, certain materials are transferred to the wafer surfaces through physical vapor deposition, or PVD, chemical vapor deposition, or CVD, and atomic-layer deposition, or ALD. Our products are critical to enabling new device architectures and ensuring device performance and manufacturing yields. These products include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Advanced precursor materials that meet the semiconductor industry's composition, uniformity and thickness requirements for deposited films; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Filtration and purification products that remove contaminants during deposition, reducing wafer defects.

**<u>Ion Implant</u>**. Ion implantation is a repeated process that introduces dopants into semiconductor wafers to enhance conductivity. Our products used during ion implant include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implant process gases and mixtures delivered through our Safe Delivery Source® ("SDS®") and Vacuum Actuated Cylinders ("VAC®") systems for safe, effective and efficient delivery; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Electrostatic chucks and proprietary low-temperature plasma coatings for core components critical to ion implantation equipment.

**<u>Chemical Mechanical Planarization</u>**. CMP is a polishing process used to planarize, or flatten, layers of material that have been deposited on silicon wafers. Our offerings include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CMP slurries for polishing semiconductor materials, including tungsten, dielectric materials, copper, tantalum (commonly referred to as "barrier"), molybdenum, aluminum, silicon carbide ("SiC") and gallium nitride ("GaN");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CMP polishing pads used with slurries across a range of polishing tools, wafers, technology nodes and applications, including tungsten, copper, and dielectrics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Formulated cleaning chemistries that remove residues from wafer surfaces after the CMP process;

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Filtration and purification solutions that remove select particles and contaminants from slurries and cleaning chemistries to prevent wafer defects; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Process monitoring and control equipment to maintain CMP slurry integrity.

**<u>Wafer and Reticle Transport</u>**. Our products, including front-opening unified pods ("FOUPs"), wafer transport and process carriers, standard mechanical interface pods ("SMIF pods") and extreme ultraviolet ("EUV") reticle pods, protect wafers and reticles from damage or abrasion and ensure purity during transportation and automated processing. This protection is essential because wafer processing involves hundreds of steps over several weeks, making damaged wafers costly to scrap.

**<u>Chemical Handling</u>**. Semiconductor and other high-technology manufacturing processes use large volumes of high-purity and hazardous chemicals. We provide solutions for handling and ensuring the purity of these chemicals, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ultra-high purity chemical container products, including drums, flexible packaging and associated coded connection systems, that maintain chemical purity, maximize utilization and ensure safe transport, containment and dispense of valuable, ultra-clean process fluids, from bulk chemical manufacturing to point-of-use in the manufacturing process; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ultra-pure valves, fittings, tubings and sensing and control products for chemical distribution throughout the fab and in wet process tools.

**<u>Wafer and Package Testing</u>**. We develop and manufacture high-performance consumable products for cleaning advanced probe cards and test sockets at semiconductor manufacturing facilities and innovative polymer products for semiconductor fabs that improve front-end tool uptime and reduce operating costs.

**INDUSTRY TRENDS**

**<u>Emerging and Existing Applications</u>**. The semiconductor market has grown significantly over the past few decades and, despite periodic downturns, we expect the long-term growth trend to continue. Products and emerging applications—including AI, high-performance and cloud computing, smartphones, wearable technology, electric and autonomous vehicles, the Internet of Things, gaming, virtual/augmented reality, and smart healthcare— will drive semiconductor demand and create significant opportunities for our products. In particular, AI workloads are fueling demand for advanced logic chips with higher transistor density and specialized architectures, as well as High Bandwidth Memory ("HBM") to support the enormous data throughput required for training and inference in large-scale models. AI is also accelerating innovation in chip packaging and interconnect technologies, such as chiplets and 2.5D/3D integration, to enable higher performance and energy efficiency in complex systems. We believe these trends position us to capitalize on growth opportunities in next-generation AI and high-performance computing by providing critical materials and process solutions that enable the production of advanced logic devices and HBM. Existing applications in data processing, wireless communications, broadband infrastructure, personal computers and consumer electronics are also expected to drive demand for semiconductors, and in turn, for our products.

**<u>Manufacturing Complexity and Device Architectures</u>**. Emerging applications require more powerful, faster and more energy-efficient semiconductors. In response, semiconductor architectures are changing and dimensions are shrinking, with increasing transistor complexity, extreme ultraviolet lithography, multilayered patterning, and vertical structures such as FinFET, 3D NAND and GAA devices. These advanced technologies and architectures require more process steps, new and innovative materials and sophisticated contamination control solutions. As manufacturers move toward atomic layer scale, materials must be delivered at increasing levels of purity from point-of-production to point-of-dispense on the wafer to maximize yields and minimize defects. We believe that the increase in process steps in lithography, deposition, CMP, etching and cleaning required to manufacture leading-edge semiconductors will increase the overall demand for our solutions.

**<u>New and Advanced Materials</u>**. New and advanced materials have played a significant role in enabling improved device performance, and we expect this trend to continue. As dimensions shrink, novel materials will be required to enable transistor connectivity. Our portfolio of critical materials includes advanced deposition materials, implant gases, CMP slurries, formulated cleaning chemistries, selective etch chemistries and high-purity wet chemicals. We believe our portfolio addresses many of the challenges our customers face as they introduce more complex architectures and new materials to improve device performance.

**<u>Materials Purity</u>**. Contamination control in a semiconductor fab is crucial for achieving acceptable device yields as feature sizes decrease and 3D structures proliferate. Our advanced filtration and purification products and solutions for air, bulk and specialty gas, and wet chemicals reduce defects and enable higher yields. Solutions such as FOUPs and high-purity drums ensure purity and protect critical materials throughout fabrication, allowing customers to store, process and transport critical

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

materials in ultra-pure environments throughout the manufacturing process. We believe that the trend for greater materials purity will provide opportunities for our innovative materials management, filtration, purification, transport and process solutions.

**<u>Geopolitical Implications of the Semiconductor Industry</u>**. Certain governments are fostering domestic semiconductor manufacturing and the broader semiconductor ecosystem through initiatives such as the United States ("U.S.") and European Union ("EU") CHIPS Acts and similar programs in Japan and Korea. We have developed a manufacturing strategy to better serve our global customers as they build new fabs in various countries and seek reliable local supply chain partners. Recent examples of this strategy include our new facilities in Kaohsiung Science Park ("KSP") in Taiwan and in Colorado Springs as well as our new Korea Technology Center in South Korea. In December 2024, we announced a definitive agreement providing for up to $77.0 million in funding under the CHIPS and Science Act in connection with our Colorado Springs facility, with installments of such award based on key milestone achievements. The Colorado Springs facility will increase service levels to new U.S. fabs and provide greater manufacturing resiliency through enhanced business continuity, while our KSP facility will enhance our ability to serve our customers efficiently and effectively in Taiwan and other Asia Pacific locations.

See "Item 1A. Risk Factors" for a more detailed description of the geopolitical risks we face.

**<u>Reliance on Trusted Suppliers</u>**. Our customers require key materials suppliers to demonstrate greater capabilities and resiliency, including sustainability, scalability, flexible manufacturing, quality control, supply chain management and effective collaboration on solutions. In response to these expectations, we leverage our manufacturing, operational and technical capabilities, along with our broad technology portfolio, to become an increasingly important and strategic trusted partner. We have established tech centers and manufacturing capabilities in strategic locations to better collaborate with and serve our customers. As we achieve greater scale, for example through the acquisition of CMC Materials, we will be able to better serve our customers, invest more in engineering, research and development ("ER&D") and bring complementary, co-optimized solutions to market faster.

**<u>Continued Consolidation</u>**. Our semiconductor customer base has increasingly consolidated through mergers and acquisitions, making the maintenance and development of strong and close customer relationships even more essential. We also seek to broaden our customer base by leveraging our core capabilities, technologies and expertise to address adjacent market opportunities.

**OUR COMPETITIVE STRENGTHS AND BUSINESS STRATEGY**

We believe our platform is well-positioned for several reasons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, our revenue was predominantly unit-driven or recurring from products consumed during semiconductor manufacturing. Our revenue is therefore more impacted by global semiconductor demand and GDP growth than by semiconductor capital equipment sales, which have historically been more cyclical.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our solutions are increasingly specified into our customers' manufacturing processes and tailored to their unique process conditions and technical roadmaps. We collaborate closely with our customers to create complementary solutions across platforms and modules, optimizing value and accelerating time to yield. Switching away from our products may be costly and time-consuming for our customers and may introduce risk to their manufacturing yields.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our broad product portfolio is not overly concentrated on any single product or product platform. In 2025, no single product platform represented more than 3% of our net sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our customer base is broad and diverse, with customers spanning the semiconductor ecosystem, including chemical companies, equipment manufacturers and semiconductor fabs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have streamlined our platform to focus on core businesses that we believe have the greatest strategic value in supporting our customers and their technology roadmaps. During 2023 and 2024, we completed the divestitures of QED, our EC business and our PIM business and terminated the Alliance Agreement with MacDermid Enthone.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We intend to continue paying down debt while investing in research and development and advanced manufacturing capabilities to maintain and expand our technology leadership and drive organic growth.

**<u>Customers Collaboration</u>**. We believe the strong relationships we have with our customers, including leading logic and memory semiconductor manufacturers, original equipment manufacturers ("OEMs") and semiconductor materials suppliers, are

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

critical to our long-term success. We have built strong relationships with our customers through our global presence, which allows us to engage with our customers where they operate. For example, we invested in our KSP manufacturing facility in Taiwan and a new research center in South Korea to collaborate locally on solutions for our customers' yield, reliability and performance challenges. We actively engage with our key customers to design technology roadmaps tailored to their strategic plans. Our customer relationships provide us with collaboration opportunities at early product design stages—in certain cases years ahead of commercialization—which enable us to introduce new products and applications that serve their needs. We intend to continue to strengthen these relationships, including through collaborations and joint development activities.

**<u>Supporting the Integration of New Materials</u>**. We understand the significant challenges our customers face as they introduce new materials into advanced semiconductor manufacturing processes. New materials must outperform incumbents and deliver equivalent or higher yields without causing integration issues with other process steps. For example, introducing a new material at the deposition stage impacts CMP, post-CMP cleans, etch and post-etch residue cleans, and filter selection across multiple process stages. We believe our ability to both manufacture new materials and support customers in evaluating how those materials interact with other manufacturing stages is a key value proposition. We leverage our understanding of upstream and downstream interactions between unit process steps to tailor product offerings that lower integration risks. We believe this approach accelerates new material introduction by reducing development cycles and improving time to market and yield for our customers.

**<u>Technology Leadership and Strong, Diverse Portfolio</u>**. Our customers require advanced, customized, reliable and cost-effective products and materials, along with technological and application expertise to enhance their productivity, quality and yield as they advance to next generation technology nodes. We believe our comprehensive offering provides us with a competitive advantage, enabling us to meet a broad range of customer needs and to serve customers across the semiconductor manufacturing ecosystem. To build upon our technology leadership, we have made, and plan to continue to make, significant investments in ER&D initiatives to continue to advance our technology and product offerings, increasingly focusing on meeting the needs of next generation technology nodes. We invested approximately $329.0 million, $316.1 million and $277.3 million on such activities in 2025, 2024 and 2023, respectively, representing 10.3%, 9.8% and 7.9% of our net sales, in 2025, 2024 and 2023, respectively. Recent product introductions include liquid filtration and purification products currently being utilized in 2 nanometer node production, advanced deposition materials for next generation transistor and interconnect technologies, polishing slurry and pad solutions with post-cleaning formulations for advanced memory applications, selective etching formulations for advanced device applications, advanced reticle pods for EUV photolithography applications, advanced 300 millimeter wafer carriers and advanced coatings meeting rigorous defectivity specifications for advanced technology node manufacturing.

**<u>Global Infrastructure</u>**. We maintain a global infrastructure of design, manufacturing, logistics, distribution, service and technical support facilities to meet the needs of our global customers. We further enhanced this footprint with our KSP facility in Taiwan, our new Colorado Springs manufacturing facility, and a new tech center in South Korea. We have also expanded capacity at existing facilities, including liquid filtration in Billerica, Massachusetts and Yonezawa, Japan, deposition materials in Toronto, Ontario, materials handling in Chaska, Minnesota and JangAn, Korea, CMP filter and CMP slurries in Taiwan, SiC slurries in Aurora, Illinois and solid precursors in Burnet, Texas.

**<u>Operational Excellence</u>.** Our customers are increasingly focused on the effectiveness, dependability, resiliency and consistency of their supply chains. Our strategy is to continue to develop our supply chain and manufacturing capabilities into a competitive advantage through operational excellence, ensuring employee safety and product quality. We intend to continue investing in the following priorities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Manufacturing equipment and facilities with leading-edge process technology, including advanced cleanroom and cleaning procedures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Automated manufacturing, statistical process controls and quality and supply chain management systems; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A skilled, agile organization capable of rapid design, prototyping and high volume manufacturing ramp while promptly responding to customer requirements.

**<u>Leveraging Our Collective Expertise</u>**. We leverage expertise across our segments and broad portfolio of advanced materials, materials handling and purification capabilities to create innovative, new and co-optimized solutions addressing unmet customer needs. For example, certain of our formulated cleaning chemistry products are developed by our MS segment with collaboration from our filtration expertise in our APS segment, packaged with our ultra-clean container and connector system, and delivered to the process tools through fluid handling systems each from our APS segment. In the process tools, these cleaning chemistry products, may be purified through systems produced by our APS segment. Our advanced deposition materials business similarly requires cross-segment capabilities, including synthesis of unique molecules, purification of these

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

materials and safe transport and delivery onto the wafer, free from contaminants, at a high throughput. As the semiconductor industry adopts new interconnect metals like molybdenum, our portfolio of deposition precursors, CMP slurries and pads, post-CMP cleans and selective etch formulations, combined with our filtration, sensing and delivery products, enables us to create complementary solutions that enhance device performance and optimize time to yield.

**<u>Strategic Acquisitions, Partnerships and Related Transactions</u>**. We have completed the integration of CMC Materials, which broadened our product and technology capabilities and increased our scale, and we streamlined our portfolio through the divestitures of QED, our EC business and our PIM business and the termination of the Alliance Agreement with MacDermid Enthone. We expect to continue pursuing strategic acquisitions and partnerships to address product offering gaps, secure new customers, diversify into complementary markets, broaden our technological capabilities, access regional markets and achieve scale benefits. We have a strong track record of executing and integrating these transactions. Prior to our acquisition of CMC Materials, we completed numerous small to mid-sized acquisitions that strengthened our product portfolio. We periodically reevaluate existing businesses and may sell, restructure or replace businesses. We also evaluate opportunities for strategic alliances, joint development programs and other strategic investments to achieve a variety of objectives including expanding our manufacturing capacity, producing products closer to our customers, accelerating product development and developing new supply sources.

**<u>Adjacent Markets</u>**. We leverage our semiconductor industry expertise and core capabilities in material science and material purity to develop product extensions for other industries requiring materials integrity management, high-purity fluids and integrated dispense systems. We plan to continue selectively developing product extensions for adjacent markets and, in doing so, seek to increase our total available market and return on ER&D investments.

**<u>Corporate Social Responsibility</u>**. Our corporate social responsibility ("CSR") program is embedded in our business strategy with 2030 goals built around four pillars: Innovation, Safety, Personal Development and Inclusion, and Sustainability. Recent accomplishments include achieving a "Gold" rating from EcoVadis (96th percentile) and a "B" rating from the Carbon Disclosure Project ("CDP"). Our annual CSR report is published on our website at http://www.Entegris.com under "About Us - Corporate Social Responsibility".

**OUR SEGMENTS**

Our business is organized and operated in two segments: Materials Solutions, or MS, and Advanced Purity Solutions, or APS. These segments collaborate to create new and increasingly integrated solutions, for example, leveraging the purification and handling expertise of the APS segment to ensure purity and stability of CMP slurries and cleans solutions from the MS segment and leveraging the advanced materials expertise from the MS segment in formulated cleaning chemistries and in slurry formulation to develop differentiated filtration and purification solutions in the APS segment.

As of December 31, 2025, we had approximately 7,700 employees, of whom approximately 51%, 15%, 11%, 9%, 7%, 5% and 2% are located in North America, Southeast Asia, Taiwan, Japan, South Korea, China and Europe, respectively. Given the variability of business cycles in the semiconductor industry and the rapid response time required by our customers, we must be able to quickly adjust the size of our production staff to meet customer demands and maximize efficiency, using skilled temporary labor when appropriate. None of our employees are represented by a labor union or covered by a collective bargaining agreement other than statutorily-mandated programs in certain international jurisdictions. We believe that our labor relations have generally been good.

**<u>Culture</u>**. Our organization is built around what we refer to as our PACE values: our core values of treating people with respect and dignity, acting honestly and consistently, encouraging creativity and innovation and a dedication to excellence. These values foster a positive work environment that allows employees to develop professionally and encourages continued innovation.

We regularly conduct employee surveys to understand their perspectives. During 2025, topics included commitment to Entegris' core values, safety and general employee satisfaction. Management uses this information to inform decision-making on employee matters, aiming to continue to be an employer of choice.

We believe that maintaining a culture of diverse perspectives, experiences and backgrounds enables us to innovate more effectively and perform better overall. To that end, we seek to promote diverse backgrounds and perspectives throughout our organization and strive to provide fair and equal opportunity for career development and advancement to all our employees. An example of this commitment is our Employee Network groups, which focus on personal development and career empowerment and foster a culture of inclusive collaboration.

**<u>Health and Safety</u>**. Our success depends on the well-being of our employees. We maintain a culture with an intense focus on safety and strive to identify, eliminate and control workplace risk to prevent injury and illness. Our employees have access to a global safety management system and are encouraged to report incidents, near misses or other observations. Management uses this information to set safety-related policies and goals for future performance.

We also design our products with end-user safety in mind. Our SDS products are designed to minimize potential leaks during transportation and use of hazardous gases, providing significant safety, environmental and productivity benefits over traditional high-pressure cylinders. Our fluid-handling products, such as tubing, valve, fittings and drum products, are used to safely store, transport and dispense volatile and dangerous chemistries, protecting those who work with them.

**<u>Total Rewards</u>**. Our total rewards program is designed to attract and retain talented employees through competitive pay, health and welfare, work-life benefits and financial wellness programs that support our employees and their families. We design our programs with the core belief that our employees are at their best when they prioritize their emotional and physical health, and we review and assess these programs annually. Examples of our benefits include a Global Employee Support Program, which provides access to mental and emotional well-being resources, and our Employee Education Assistance Program, which supports continued education to advance careers at Entegris. We also have a global Rewards and Recognition program that recognizes outstanding individual achievement that earn tangible business results, reinforcing our corporate values and culture.

**<u>Talent Development and Training</u>**. We are committed to the ongoing training and development of our employees. We foster an on-the-job training and development culture by investing in rotational development programs in operations, supply chain, and engineering. We continuously expand technical and leadership training through our Entegris Great Leader Profile, Management Achievement, and Supervisor Training programs to advance leadership and management skills for career growth. Employees receive feedback and development discussions through formal and informal review sessions throughout the year. While we continue to search for new perspectives with external hires, we also provide opportunities for employees to grow their careers at the Company and regularly fill open vacancies with internal candidates. Management systematically assesses succession planning for key positions and identifies high potential employees for future growth and development.

**<u>Oversight</u>**. Our Board of Directors, through the Management Development and Compensation Committee, oversees human capital matters. This includes receiving regular updates from our Senior Vice President, Global Human Resources, and facilitating discussion on workforce initiatives, employee surveys, hiring and retention, demographics, labor relations, compensation and benefits, succession planning and training. The Board's oversight helps identify and mitigate labor and human capital management risks, and is part of the broader framework that guides how we attract, retain and develop a workforce that aligns with our values and strategies.

For additional information on these important initiatives, see our annual corporate social responsibility report on our website at http://www.Entegris.com under "About Us - Corporate Social Responsibility."

**OUR HISTORY**

Entegris has been helping customers solve critical materials challenges and enhance manufacturing yields for almost 60 years, tracing its corporate origins to Fluoroware, Inc., which began operating in 1966. The Company was incorporated in Delaware on March 17, 2005 through a merger of Entegris, Inc., a Minnesota corporation, and Mykrolis Corporation, a Delaware corporation. The Company subsequently acquired ATMI, based in Danbury, Connecticut, on April 30, 2014 and CMC Materials, based in Aurora, Illinois, on July 6, 2022.

**Risks Related to Our Business and Industry**

***Our revenue is primarily dependent upon demand from the global semiconductor ecosystem. Fluctuations in demand, whether from industry cyclicality, changes in consumer spending, macroeconomic conditions, or other factors, may cause our revenues and operating results to vary significantly, which could adversely affect our business.***

Our revenue is primarily dependent upon demand from the global semiconductor ecosystem. The semiconductor industry has historically been, and is likely to continue to be, cyclical with periodic downturns, resulting in decreased demand for our products, which has negatively impacted our results of operations in the past and could do so again in the future. Our revenues and operating results may fluctuate significantly from quarter-to-quarter or year-to-year due to a number of factors, many of which are outside our control. A lower volume of sales can have a large and disproportionate impact on our profitability because some of our expenses are fixed in the short term.

Factors that may negatively impact the demand for our solutions or cause our financial results to fluctuate unpredictably include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• decreased consumer spending or changes in purchasing habits related to (1) macroeconomic uncertainty, market conditions, slow or negative economic growth or uncertainty about economic and other policies; or (2) geopolitical instability, including the Russian invasion of Ukraine and conflicts in the Middle East;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• trends in the semiconductor industry and demand trends for different types of electronic devices such as logic versus memory integrated circuit ("IC") devices, or digital versus analog IC devices, and the various technology nodes at which those products are manufactured;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer considerations, which may impact their future purchasing decisions, including (1) the size and timing of customer orders; (2) customers' decisions to accelerate, decelerate or delay shipments; (3) customer inventory management and corrections; (4) customers' rate of use and replacement of our consumable products; (5) customers' decisions to delay expansion projects; (6) customers' device architectures and specific manufacturing processes; (7) consolidation of our customers; and (8) the relative success of our customers vis-à-vis each other;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the short order-to-delivery time for our products; market share and competitive losses; and pricing changes by us and our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• legal, tax, accounting or regulatory changes (including changes in import/export regulations and tariffs, such as regulations imposed by the U.S. government restricting exports to China or regulations imposed by other countries restricting the export of certain materials or the re-export of products containing such materials, or potential additional tariffs on imports, and tariffs imposed by other countries) or changes in the interpretation or enforcement of existing requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• procurement shortages and related increased prices, and the failure of suppliers to perform their obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our capital expenditure requirements to meet demand for our solutions, and the schedule and timing, including potential delays, thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unanticipated manufacturing difficulties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in average selling prices, customer mix and product mix;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to develop, introduce and market new, enhanced and competitive products in a timely and cost-effective manner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our competitors' introduction of new products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disruptions in transportation, communication, demand, IT or supply resulting from factors outside of our control, including strikes, acts of God, wars, terrorist activities, international conflict and natural or man-made disasters; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• foreign currency exchange rate fluctuations.

During downturns in the semiconductor industry, which can occur suddenly, we typically experience greater pricing pressure and shifts in product and customer mix, which can adversely affect our gross margin and net income. The semiconductor industry is also affected by seasonal shifts in demand, and as a result, we have in the past experienced and may experience in the future short-term fluctuation in our results of operations from one period to the next. We are unable to predict the timing, duration or severity of any current or future downturns in the semiconductor industry and cost control or other measures we implement to maintain profitability during such downturns or periods of limited growth may constrain or limit our ability to capitalize on subsequent industry recoveries.

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

Furthermore, the semiconductor industry is subject to rapid advancements and demand for new and emerging technologies, such as AI. If we do not have, or are unable to develop, products and solutions that are utilized to manufacture semiconductors that enable new end-user demand trends, we may not be able to grow our revenue as fast as anticipated and our results of operations may be impacted. Furthermore, our performance is dependent, in large part, on our exposure to certain market trends and the growth of certain segments of the semiconductor ecosystem. For example, we have less exposure to the market for back-end assembly and testing. If certain markets in which we have limited or no exposure grow more rapidly than the markets we serve, our growth relative to our competitors may lag.

To remain competitive in the semiconductor industry, we have in the past, and will likely in the future, maintain or increase our ER&D activity and invest in our infrastructure, even during downturns and periods of slower demand. Additionally, if we do not, or are unable to, adequately anticipate changes in our business environment, we may lack the infrastructure, manufacturing capacity and resources to scale up our business to meet customer expectations and compete successfully during a period of growth. Conversely, we may expand our capacity too rapidly, resulting in excess fixed costs and lower profitability.

***As a result of global economic uncertainty, we may experience reduced demand for our products, increased costs, challenges in forecasting our operating results and identifying and prioritizing business risks, and other negative effects, any of which may materially and adversely affect our business, financial condition and results of operations.***

Uncertain and volatile economic conditions, including financial market instability, inflation and increased costs, trade wars, fluctuating interest rates, economic slowdowns and/or recessions, difficulties in obtaining capital, and national debt and bank failures, could materially and adversely impact our operating results. Such conditions, particularly if present in any of our key sales or manufacturing regions, can cause or exacerbate negative trends in business and consumer spending, which, in turn, historically have increased our manufacturing and delivery costs and reduced customer demand for our products (and may do so in the future). We may also face a number of other negative effects related to global economic uncertainty, including.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an increase in reserves for accounts receivable due to our customers' inability to pay us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lower utilization of our manufacturing facilities, which could lead to lower margins;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an increase in write-offs for excess or obsolete inventory that we cannot sell;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• potential impairment charges relating to goodwill, intangible assets, manufacturing equipment or other long-lived assets, to the extent that any downturn indicates that the carrying amount of the asset may not be recoverable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an inability of suppliers to deliver parts and raw materials, which would negatively affect our ability to manage operations, manage our costs and sell our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidation or strategic alliances among other suppliers to semiconductor manufacturers, which could adversely affect our ability to compete effectively;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• greater challenges in forecasting operating results, making business decisions and identifying and prioritizing business risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a need to undertake additional cost reduction efforts, including additional restructuring activities, which may adversely affect our ability to capitalize on opportunities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on our ability to access cash maintained in our bank accounts as a result of bank failures, which could affect our ability to manage our operations.

***Interruptions in our supply chain, including those from our sole, single and limited source suppliers, could affect our ability to manufacture our products and meet demand, which, in turn, could have an adverse effect on our revenue and results of operations.***

Our ability to increase sales of our products depends in part upon our ability, in a very short timeframe, to ramp up our manufacturing capacity and to mobilize our supply chain. If we are unable to do so, our customers could obtain products from our competitors, which would reduce our market share, harm our reputation as a trusted partner and impact our results of operations. Ensuring a robust and resilient supply chain is critical for us to meet the demand, quality and technological requirements of our customers. We rely on the timely delivery of parts, materials and services, including components and subassemblies, from our suppliers and contract manufacturers.

The Company's strategies to limit its reliance on single, sole or limited source suppliers and utilize alternative sources are not feasible or practical in all circumstances. For example, we rely on single, sole or limited source suppliers for certain raw materials that are critical to manufacturing our products, such as plastic polymers, filtration membranes, abrasive particles, petroleum coke and other materials. If we were to lose any of these critical sources, or there is an industry-wide increase in demand for, or discontinuation of, raw materials or components used in our products, it could be difficult or impossible to find an alternative supplier, which could adversely affect our operations. In addition, qualifying alternative suppliers or materials (or relocating manufacturing) can be time-consuming and costly due to customer qualification requirements, regulatory approvals,

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

and the technical sensitivity of many of our products. Disruptions to transportation routes, ports, air freight capacity, or regional infrastructure in Asia (including in locations where we or our suppliers manufacture or where key customers operate) could further delay deliveries, increase costs, or reduce our ability to serve customers.

Several factors outside of our control, including, but not limited to, surges in demand for semiconductors, changes in trade policies, the imposition of foreign export controls on critical materials and minerals and international conflicts, have resulted in, and may in the future result in, a shortage of raw materials and components needed to manufacture and deliver our products, higher raw materials costs, costly and time-consuming re-qualification of products manufactured with new raw materials and delays in, and unpredictability of, shipments due to transportation interruptions. These results could harm our reputation or the competitiveness of our products. Such shortages, delays and unpredictability have adversely impacted, and may impact in the future (1) our suppliers' ability to meet our demand requirements, (2) our manufacturing operations, (3) our ability to meet customer demand, (4) our gross margins and (5) our other operating results. Our actions to counteract adverse impacts to our gross margins and other operating results could be unsuccessful or reduce demand, which would adversely impact our revenue. Additionally, our suppliers may not have the capacity to meet increases in our demand for raw materials and other components, in turn, making us unable to meet customer demand for our products. If our suppliers or sub-suppliers are unable to maintain their operations due to operational restrictions or financial hardship caused by an economic slowdown or recession, we may need to increase our safety stocks of raw materials or components or alter our payment terms with such suppliers, including prepaying for raw materials. These measures could reduce our available working capital, increase our inventory carrying costs, and negatively impact our liquidity and overall financial flexibility.

Further, increased restrictions imposed on a class of chemicals known as per- and polyfluoroalkyl substances ("PFAS"), which are used in a number of products, including parts and materials that are incorporated into our products, may negatively impact our supply chain due to the potentially decreased availability, or non-availability, of PFAS-containing products. Proposed regulations under consideration could require that we transition away from the usage of PFAS-containing products, which could adversely impact our business, operations, revenue, costs, and competitive position. Suitable replacements for PFAS-containing parts and materials may not be available at similar performance and costs, or at all.

***Because a significant amount of our sales and manufacturing activity occurs outside the U.S., we are exposed to risks inherent in operating a global business, including changes in economic policy, geopolitical tensions and challenges in managing a diverse workforce and operating under differing business and legal environments, which may harm our reputation or profitability.***

Sales to customers outside the U.S. accounted for approximately 82%, 79% and 75% of our net sales in 2025, 2024 and 2023, respectively. We anticipate that international sales will continue to account for a majority of our net sales. In addition, a number of our key domestic customers derive a significant portion of their revenues from sales in international markets. We also develop and manufacture a significant portion of our products outside the U.S. and depend on international suppliers for many of our parts and raw materials. We intend to continue to maintain extensive sales, product development and manufacturing operations internationally, which are subject to a number of risks, uncertainties and potential costs that could adversely affect our revenue, profitability and reputation, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes and uncertainties with respect to trade and export regulations (including new and changing regulations for exports of certain technologies to China), trade policies and sanctions, tariffs, international trade disputes and any retaliatory measures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• geopolitical tensions or conflicts, such as Russia's invasion of Ukraine, the ongoing conflict in the Middle East, and tensions between China and Taiwan and between China and the U.S.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cybersecurity incidents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges in hiring and integrating workers in different countries and in managing a diverse workforce with different experience levels, languages, cultures, customs, business practices and worker expectations, along with differing employment practices and labor issues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges of maintaining appropriate business processes, procedures and internal controls and complying with legal, environmental, health and safety, anti-bribery, anti-corruption, trade compliance, data privacy, cybersecurity and other regulatory requirements that vary by jurisdiction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges in developing relationships with local customers, suppliers and governments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public health crises;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in interest rates and currency exchange rates, including the relative strength or weakness of the U.S. dollar against foreign currencies that are important to our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liability for foreign taxes assessed at rates higher than those applicable to our domestic operations;

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• imposition of a global minimum tax rate, including by the Organization of Economic Co-operation and Development ("OECD");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges and costs associated with the protection of our intellectual property throughout the world;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges associated with managing global and regional third-party service providers, including certain engineering, software development, manufacturing, IT and other functions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer or government efforts to encourage operations and sourcing in a particular country, such as Korea or China, including efforts to develop and grow local competitors, require local manufacturing, and provide special incentives to government-backed local customers to buy from local competitors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impacts of natural disasters and extreme and chronic weather events on our operations and those of our customers and suppliers, which may be exacerbated by climate change.

In the past, these factors have disrupted our operations and increased our costs, and we expect that these factors will continue to do so in the future. Furthermore, there is inherent risk, based on the complex relationships among China, Japan, Korea, Taiwan, and the U.S., that political, diplomatic and national security influences could lead to disputes, impacts and/or disruptions, in particular those affecting the semiconductor industry. This can adversely affect our business with China, Japan, Korea, and/or Taiwan and potentially the entire Asia Pacific region or global economy. A significant dispute, impact and/or disruption in any area where we do business could have a materially adverse impact on our future revenue and profits.

***Export controls, economic sanctions, and other similar restrictions may limit our ability to sell our products to certain customers, require us to obtain governmental licenses, put the Company at a competitive disadvantage both domestically and internationally and expose us to additional legal liability, all of which could harm our business and financial condition.***

We are subject to export control and economic sanctions laws and regulations that restrict the delivery of some of our products and services to certain countries (and nationals thereof), to certain end users, and for certain end uses. These restrictions may prohibit the sale of certain of our products, services and technologies, and they may require us to obtain a license from the U.S. government and/or other governments before delivering the controlled item or service. Obtaining export licenses may be difficult, costly and time-consuming, and we may fail to receive licenses that we apply for on a timely basis or at all. Even where a license is ultimately granted, the licensing process may result in extended delivery timelines, increased administrative burden, and customer uncertainty, any of which could cause customers to delay, reduce, or cancel orders, shift purchases to competitors, or redesign processes around non-U.S. alternatives. In addition, export controls and sanctions regimes are dynamic and may be expanded to cover additional products, technology, end uses, end users, or jurisdictions (including through restrictions applicable to non-U.S. persons or foreign subsidiaries), which could further limit our ability to sell or support products and services in certain markets. We must also comply with export control and economic sanctions laws and regulations imposed by other countries. Although we maintain an export and trade control compliance program, it may not be fully effective or may be circumvented, exposing us to legal liabilities. Compliance with these laws could significantly limit our sales in the future. Changes in, or responses to, U.S. or other countries' trade controls could reduce the competitiveness of our products and cause our sales to decline, which could have a material adverse effect on our business, financial condition and results of operations.

Over the last several years, the U.S. and other governments have significantly expanded export controls on certain technologies and commodities to certain markets, particularly with respect to semiconductor and other high technology exports to China, a market which represented approximately 21% of our sales in 2025. These and other regulations have reduced our ability to sell our products to customers in China and it is possible future regulation could further reduce demand for our products. As a result of these restrictive measures, certain of our customers have made efforts to source products domestically in order to mitigate perceived risks to their supply chain. Furthermore, these restrictive measures have incentivized Chinese domestic semiconductor companies to work more closely with local Chinese companies and companies headquartered outside of the U.S. in an effort to enable these companies to enhance the technology-level and quality of their products and, as a result, to better compete with our products. We may be unable to continue to compete favorably against these local and foreign competitors. If these efforts are successful, are widespread amongst our customers and expand to our products and solutions broadly, overall global demand for our products may be reduced, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, government authorities may take retaliatory actions, impose conditions that require the use of local suppliers or partnerships with local companies, increase tariff and other customs costs, impose export restrictions on raw materials and components, such as the restrictions imposed on critical materials and minerals by China in 2025, or require the license or other transfer of intellectual property, which could have a significant adverse impact on our business.

These measures could also increase our costs (including logistics, compliance, and supplier qualification costs), disrupt our sourcing and manufacturing plans, and adversely affect our ability to meet customer requirements or contractual commitments.

***A significant portion of our sales is concentrated on a limited number of key customers, and our net sales and profitability may materially decline if we were to lose one or more of these customers.***

Sales to a limited number of large customers constitute a significant portion of our overall revenue, shipments, cash flows, collections and profitability and our success is tied in part to their competitive position in their respective markets. Our top ten customers accounted for 50%, 48% and 43% of our net sales in 2025, 2024 and 2023, respectively. Consolidation among semiconductor manufacturers, shifts in customer build plans, and evolving procurement strategies (including efforts to localize supply chains in response to export controls or trade policies) may increase these customers' bargaining power and result in pricing pressure, more restrictive commercial terms (including audit, cybersecurity, ESG, and flow-down requirements), longer payment cycles, or demands for dual sourcing or rapid qualification of alternative products. If we are unable to satisfy these requirements on commercially reasonable terms, we could lose design wins, experience reduced volumes, or incur additional costs, any of which could materially adversely affect our results of operations.

Because we have limited or no contractual recourse if our customers decided to stop buying and using our products with limited advance notice, the cancellation, reduction or deferral of purchases of our products by any one of these customers could significantly reduce our revenues in any particular quarter. If we were to lose any of our significant customers, if our products are not specified for our significant customers' products, if our customers lose market share to competitors with whom we do not have as strong relationships or as favorable commercial terms, or if we suffer a material reduction in their purchase orders, our revenue could decline and our business, financial condition and results of operations could be materially and adversely affected. Due to the long design and development cycle and lengthy customer product qualification periods required for most of our products, we may be unable to replace these customers quickly, if at all. In addition, our principal customers hold considerable purchasing power and may be able to negotiate sales terms that result in decreased pricing, increased costs, lower margins and/or limit our ability to share jointly-developed technology with others. The semiconductor industry may continue to undergo consolidation, and if any of our customers merge or are acquired, we may experience lower overall sales to, or lower profitability from sales to, the merged or combined companies. Furthermore, we rely on independent distributors, in addition to our direct sales force, to market and sell certain of our products globally. If these distributors fail to devote sufficient resources to selling our products or are otherwise unsuccessful in doing so, our revenue and results of operations could be materially adversely affected.

Our customer base is also geographically concentrated, particularly in Taiwan, Korea, Japan, China and the U.S. As a result, export regulations, the imposition of tariffs or other trends that apply to customers in certain countries, such as those in China, have exposed and may further expose our business and results of operations to greater volatility. The geographic concentration of our customer base could shift over time as a result of changes in technology and competitive landscape, as well as government policy and incentives to develop regional semiconductor industries.

***If we are unable to anticipate and respond to rapid technological change and customer requirements by continuing to innovate and introduce new and enhanced products and solutions, we may experience a loss of market share, decreased sales, revenue, profitability and damage to our reputation.***

The semiconductor industry is subject to rapid technological change, changing customer requirements and frequent new product introductions. In our industry, the first company to introduce an innovative product that addresses an identified market need will often have a significant advantage over competing products. Following development, it may take several years for sales of a new product to reach a substantial level, if ever. If a product concept does not progress beyond the development stage or only achieves limited acceptance in the marketplace, we may not receive a direct return on our expenditures, which may be significant, we may lose market share and our revenue, and profitability may decline. In the past, we incurred significant impairment charges for capital expenditures related to developing the capability to manufacture shippers and FOUPs for 450 millimeter wafers, which major semiconductor manufacturers announced that they would not initiate manufacturing for the foreseeable future, and for other projects that failed to find commercial viability.

We believe that our future success will depend upon our ability to continue to develop novel, mission-critical solutions to maximize our customers' manufacturing yields and enable higher performance semiconductor devices. A failure to successfully anticipate and respond to technological changes by developing, marketing and manufacturing new products or enhancements to our existing products could harm our business prospects, limit our market share, result in unanticipated costs and significantly reduce our sales. Developing new products or enhancing existing products is complex, costly and uncertain, and, if a new product is adopted by our customers, we must ramp manufacturing quickly, while also managing costs. In addition, our customers impose very high quality and reliability standards on our products, which often change and can be difficult and costly to achieve. A failure to satisfy these customer standards or to comply with industry, regulatory and technical requirements may

------

result in reduced orders, higher manufacturing costs, delays in acceptance and payment, additional service and warranty expense and damage to our reputation, which may adversely affect our revenue and results of operations.

***Manufacturing interruptions or delays, or other disruptions to our operations, could adversely affect our business, financial condition, results of operations and reputation.***

Our manufacturing processes are complex and require the use of expensive and technologically sophisticated equipment and materials. We have, on occasion, experienced manufacturing difficulties, such as critical equipment breakdowns, delayed ramp up of newly constructed or expanded manufacturing facilities or the introduction of impurities in the manufacturing process, which cause lower yields, delivery delays and harm our ability to serve our customers. In addition, any modification to the manufacturing process of a product, including changes designed to improve manufacturing yields, process stability and product quality, could require that the product be re-qualified by customers, which can increase our costs and delay or prevent our ability to sell this product to our customers. We have moved, and we may in the future move, the manufacture of certain products from one plant to another, which may be costly and time-consuming. If we fail to transfer and re-establish the manufacturing processes in the destination plant efficiently and effectively, we may not be able to meet customer demand, we may lose credibility with our customers and our business may be harmed. Even if we successfully move our manufacturing processes, we may not achieve the anticipated levels of cost savings or efficiencies, if any, and such disruptions may cause delays in developing or shipping our products. These and other manufacturing difficulties may result in the loss of sales and exposure to warranty and product liability claims.

Disruptions to our operations may be caused by factors outside of our control, including severe weather events and natural catastrophes, civil unrest, outbreaks of disease, and terrorist actions. Our continuity plans may be insufficient to mitigate the impact of disruptions to our operations, and any prolonged disruption may impede our ability to manufacture and deliver products to our customers or to engage with customers on new product applications, resulting in an adverse impact on our business and results of operations.

***We may be subject to IT system failures, network disruptions and cybersecurity and data breaches, which could damage our reputation and adversely affect our financial condition, results of operations and cash flows. New laws and regulations regarding data privacy may also increase our costs.***

In conducting our business, we use, collect and store sensitive data, including our financial information, intellectual property, confidential information, proprietary business information and personally identifiable information of our employees and others, as well as similar information of our customers, suppliers and business partners. We maintain this information in our data centers, on our networks and on IT systems owned and maintained by third parties. The secure processing, maintenance and transmission of this information is critical to our operations. All IT systems are subject to disruptions, security breaches, outages and failures, which may be caused by a variety of internal and external factors. We and our third-party suppliers have experienced, and expect to continue to be subject to, cybersecurity threats and incidents ranging from employee or contractor error or misuse to individual attempts to gain unauthorized access to systems, to sophisticated and targeted measures known as advanced persistent threats. Cybersecurity threats may target us directly or indirectly through our third-party providers and global supply chain. Cybersecurity attacks are increasing in number and the attackers are increasingly organized and well-financed, or at times supported by state actors. Geopolitical tensions or conflicts, such as Russia's invasion of Ukraine and tensions with China, have created a heightened risk of cybersecurity attacks. AI capabilities are and will be used by threat actors to identify vulnerabilities and craft increasingly sophisticated cybersecurity attacks, making them even more difficult to defend against by creating more effective phishing emails or social engineering and by exploiting vulnerabilities in electronic security programs utilizing false image or voice recognition. The use of AI by us, our customers, suppliers and other business partners and third-party providers may introduce vulnerabilities onto our IT systems. We may be unable to anticipate, prevent or remediate future attacks, vulnerabilities, breaches or incidents and in some instances we may be unaware of vulnerabilities or cybersecurity breaches or incidents or their magnitude and effects, particularly as attackers are increasingly able to circumvent controls and remove forensic evidence.

We continue to devote significant resources to network security, threat monitoring and other measures to protect our systems and data from unauthorized access or misuse, and we may be required to expend greater resources in the future, especially in the face of evolving and increasingly sophisticated cybersecurity threats and laws, regulations, contractual and other actual and asserted obligations to which we are or may become subject relating to privacy, data protection, and cybersecurity. These security procedures and protection systems are costly and yet they may not be fail-safe. We may still suffer cybersecurity and other incidents, which could have a material adverse effect on our business or operations.

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

IT system failures, network disruptions and breaches of data security could (1) cause disruption in our operations, issues with customer communication and order management, the unauthorized or unintentional disclosure of sensitive information, or disruptions in our transaction processing or (2) undermine the integrity of our disclosure controls and procedures and our internal control over financial reporting, which could affect our reputation, result in significant liabilities and expenses, adversely affect our ability to report our financial results in a timely manner and could have a material adverse effect on our financial condition, results of operations and cash flows. Cybersecurity incidents affecting our suppliers could impact our supply chain, which, in turn, could lead to difficulties and delays in our ability to obtain parts, materials and services needed to manufacture our products and provide services. Failure to timely recover from such delays could materially and adversely affect our business, financial condition and results of operations, and may also cause our business and financial outlook to be inaccurate.

Our efforts to comply with current and evolving laws, regulations and other obligations, such as contractual or commercial obligations from our customers or other third parties, concerning privacy, cybersecurity, and data protection, increase our compliance costs and could result in significant additional expenses. Any actual or alleged failure to comply with these obligations could result in inquiries, investigations, and other proceedings against us by regulatory authorities or other third parties.

***Recent tariffs and other trade actions taken by the U.S. and other countries where we do business have increased, and may continue to increase, our import and export costs, requiring us, in certain situations, to increase our prices, add a surcharge or find alternative suppliers which, in turn, may harm our relationships with customers, reduce demand for our products and decrease our profitability.***

In recent years, including during 2025, the U.S. government has imposed tariffs and implemented other trade actions affecting products and materials imported into the U.S. In response to these tariffs and other changes in U.S. trade policy, several countries, including China, have threatened or imposed retaliatory tariffs on U.S. exports. The continuing imposition of tariffs by the U.S. and others may also give rise to further escalations of protectionist and retaliatory trade measures. Tariffs and related trade measures may be expanded, modified or restructured, and exemptions or exclusions may be limited or unavailable, which could further increase costs or disrupt supply chains.

These tariffs and other trade measures could have a material adverse effect on our business, results of operations, or financial condition. Our business and operating results are heavily dependent on international trade. We import raw materials and finished goods into the U.S. and we export products from the U.S. to our customers throughout the world, including those in China. Because of the recent tariffs and other trade restrictions, we have experienced increased and additional costs with respect to our import and export of such materials, finished goods, and products, and we may continue to experience these costs. In turn, we may be required to increase the prices of our products or add surcharges, which may reduce demand and harm our relationships with our customers. If we do not, or are unable to, increase prices or add surcharges without reducing demand, we may experience reduced profitability. Furthermore, retaliatory tariffs imposed by countries where we have significant sales, like China, could cause our customers to source products from local and non-U.S. competitors, which could further reduce demand for, and the overall competitiveness of, our products and decrease our market share. Additionally, we may be required to source our materials from alternative suppliers which could significantly increase our costs, lead to significant delays, and result in reliability or quality issues, all of which could harm our reputation and decrease demand for our products. The extent and duration of the tariffs and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations and overall relationships between the U.S. and affected countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our products in affected markets.

***Our operations use hazardous materials that expose us to various risks, including potential liability for personal injury and potential remediation obligations.***

Our operations involve, and we are exposed to the risks associated with, the use and manufacture of hazardous materials. In particular, we manufacture specialty chemicals, which is an inherently hazardous process that may result in accidents, and store and transport hazardous raw materials, products and waste in, to and from various facilities. Potential risks that may disrupt our operations or expose us to significant losses and liabilities include explosions and fires, chemical spills and other discharges, releases of toxic or hazardous substances or gases, and pipeline and storage tank leaks and ruptures. These and other hazards may result in (1) liability for personal injury, death, damage to property and contamination of the environment; (2) suspension of operations; (3) the imposition of civil or criminal fines, penalties and other sanctions; (4) cleanup costs; (5) claims by governmental entities or third parties; (6) reputational harm; (7) increases in our insurance costs; and (8) other adverse impacts on our results of operations. Moreover, a failure of one of our products at a customer site could interrupt the business operations of the customer. For example, while we believe that our SDS and VAC delivery systems are safe to transport, store and deliver toxic gases, any leakage could cause serious damage, including injury or death, to any person exposed to those toxic gases,

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

potentially creating significant product liability exposure for us. Our insurance coverage may be inadequate to satisfy any such liabilities, and our financial results or financial condition could be adversely affected.

***We carry a significant amount of goodwill on our balance sheet.***

As of December 31, 2025, we had goodwill of $3,946.7 million. The future occurrence of a potential indicator of impairment, such as a significant adverse change in business climate, an adverse action or assessment by a regulator, unanticipated competition, a material negative change in relationships with significant customers, strategic decisions made in response to economic or competitive conditions, loss of key personnel, or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed of, could result in goodwill impairment charges. We have recorded goodwill impairment charges in the past, and such charges have materially affected our historical results of operations. For additional information see Note 8 – Goodwill and Intangible Assets to the accompanying consolidated financial statements.

***Loss of any of our key personnel could harm our business, and our inability to attract and retain new qualified personnel could inhibit our ability to operate and grow our business successfully.***

Many of our key personnel have significant experience in the semiconductor industry and deep technical expertise. The loss of our key employees or an inability to attract, hire, train, motivate and retain qualified and skilled employees, particularly research and development and engineering personnel, could cause business interruptions and inhibit our ability to operate and grow our business. As the semiconductor industry has grown in recent years, competition for qualified talent, particularly those with significant industry experience, has intensified. Other factors impacting our ability to attract and retain key employees include the attractiveness of our compensation and benefit programs, global economic or political conditions, the ability to obtain necessary authorizations for workers to provide services outside their home countries and our ability to continue to foster a challenging and rewarding work environment. We have experienced in the past, and may in the future continue to experience, an increasingly competitive and constrained labor market, which may limit our ability to add headcount required to meet our customers' demand, decrease our productivity due to an influx of inexperienced workers and cause our labor costs to increase and our profitability to decline. As a result, the difficulty and costs associated with attracting and retaining employees has risen and may continue to rise.

***If we fail to obtain, protect and enforce intellectual property rights, our business and prospects could be harmed.***

Our future success and competitive position depend in part upon our ability to obtain, maintain and enforce intellectual property rights. We rely on patent, trade secret and trademark laws as well as confidentiality agreements to protect many of our major product platforms. Even if patents are issued in respect of our patent applications, these patents may nonetheless (1) expire; (2) be challenged, invalidated, circumvented, rendered unenforceable or otherwise compromised by third parties; or (3) fail to provide us with any competitive advantage. We may lose trade secret protections as a result of actions or omissions by us, our employees, or third parties. Our confidentiality agreements (including confidentiality agreements entered into between us and our employees) may be breached and the remedies for any such breach may be inadequate. Our confidential and proprietary information and technology may also be replicated or obtained through lawful means. Replication of our intellectual property or the infringement or misappropriation of our intellectual property rights could result in uncompensated lost market and revenue opportunities, which could adversely affect our business and financial condition. Monitoring and detecting any unauthorized access, use or disclosure of our intellectual property is difficult and costly and we cannot be certain that the protective measures we have implemented will completely prevent misuse. Our failure to monitor and ensure the proper use of our data, confidential information, and intellectual property in the training and operation of generative artificial intelligence products may result in the loss of intellectual property and raise complex compliance, intellectual property and other issues.

We have initiated, and may initiate in the future, litigation in order to enforce our intellectual property rights, protect our trade secrets, and determine the validity and scope of the proprietary rights of others. From time to time, third parties have also asserted, and may continue to assert, intellectual property claims against us and our products. In the past, intellectual property-related litigation has been time consuming and has caused us to expend significant financial and other resources. In the future, such litigation could (1) impose substantial costs and cause the diversion of resources and the attention of management; (2) require us to pay damages or royalties; (3) require us to alter our products or processes, or obtain a license to continue selling the impacted product, which we may be unable to do on commercially acceptable terms, or at all; (4) severely harm our reputation and competitive position; and (5) negatively affect our sales, profitability and prospects to commercialize new products.

***As we incorporate AI capabilities into our operations, we may be subject to various risks, including compliance risks, the potential for AI to produce inaccurate results, intellectual property and cybersecurity risks, and the risk that we are unable to use AI as successfully as our competitors, which may result in legal liability, reputational damage and other harm to our business.***

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

AI technology is complex and rapidly evolving, as are the operational, competitive, legal and regulatory environments in which it exists. We are increasingly incorporating AI capabilities into our business operations and our ways of working, which can be both challenging and costly. For example, we may experience difficulty in effectively using, or be unable to use, AI in a manner that benefits our business operations, enhances our efficiency and enables us to improve our products and services more rapidly. AI algorithms or training methodologies may also be flawed, and datasets may contain irrelevant, insufficient or biased information, which can cause errors in outputs. This may give rise to legal liability, reputational damage and other adverse effects. Our business may be further negatively impacted if our competitors are more successful than we are in executing their AI strategies and developing superior products and services with the aid of AI technology.

In addition, the use of AI in the development of our products and services could cause the loss of intellectual property, as well as subject us to risks related to intellectual property infringement or misappropriation, data privacy and cybersecurity. Countries may also adopt laws and regulations related to AI that could cause us to incur greater compliance costs or limit the use of AI in our business. Any failure or perceived failure by us to comply with such legal or regulatory requirements could subject us to legal liabilities, damage our reputation, or otherwise have a material and adverse impact on our business.

***Implementation of, and reporting on, our environmental, social and governance commitments could result in additional costs, and our inability to achieve these commitments could have an adverse impact on our reputation and performance.***

From time to time we communicate our strategies, commitments and targets related to sustainability, greenhouse gas emissions, the sustainability of our products, human rights, and other environmental, social and governance matters. These strategies, commitments and targets reflect our current plans and aspirations, and we may be unable to achieve them. Changing customer sustainability requirements, including increasing customer demand for sustainable products, as well as actions taken to achieve our sustainability targets, could cause us from time to time to alter our manufacturing, operations or products, and incur substantial additional expense. Any failure or perceived failure to timely meet these sustainability requirements or targets could adversely impact the demand for our products and subject us to significant costs and liabilities and reputational risks that could adversely affect our business, financial condition and results of operations. In addition, standards and processes for measuring and reporting greenhouse gas emissions and other sustainability metrics may change over time, increase our costs and result in inconsistent data or significant revisions to our strategies, commitments and targets, and our ability to achieve them. We also are or may become subject to new climate and sustainability laws and regulations, such as the State of California's climate change disclosure rules, the EU's Corporate Sustainability Reporting Directive and the SEC's rules on climate-related risks. Compliance with such laws and regulations, as well as increased scrutiny from regulators, customers and other stakeholders in our sustainability practices, could result in additional costs and expose us to new risks, including reputational risks. Any scrutiny of our greenhouse gas emissions or other sustainability disclosures or our failure to achieve related strategies, commitments and targets, or our failure to disclose our sustainability measures consistent with applicable laws and regulations or to the satisfaction of regulators or our stakeholders, could negatively impact our reputation or performance.

**Risks Related to Government Regulation**

***We are subject to a variety of rapidly evolving environmental laws and regulations that could cause us to incur significant liabilities and expenses.***

The wide variety of federal, state, local and non-U.S. regulatory requirements relating to the design, manufacture, sale, shipping, import, export and use of our products, as well as the release, use, storage, treatment, transportation, discharge, disposal and remediation of, and human exposure to, hazardous chemicals, could result in future liabilities, remediation efforts or the suspension of production or shipment. These requirements are dynamic and have become stricter over time. These laws and regulations, among others, increase the complexity and costs of operating our facilities and manufacturing and transporting our products. Further changes to, or our failure to comply with, these and similar regulations could (1) restrict our ability to expand, build or acquire new facilities, (2) require us to acquire costly control equipment, (3) cause us to incur expenses associated with remediation of contamination, (4) cause us to modify our product design, operations, manufacturing or shipping processes or (5) otherwise increase our cost of doing business, which may have a negative impact on our financial condition, results of operations and cash flows. In addition, the potential adoption of new laws, rules or regulations related to climate change and the use or sale of PFAS-containing products poses risks, including subjecting us to future costs and liabilities, that could harm our results of operations or affect the way we conduct our businesses. New or modified regulations could require us to make substantial expenditures to enhance our environmental compliance efforts, or to reformulate our products or substitute raw materials or components with alternatives that may be more expensive, less readily available, or inferior in quality or performance. Any such changes could increase our production costs, weaken our supply chain, or result in less competitive products and may require requalification by our customers, which could result in delays, loss of design wins, or customers transitioning to competing products..

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

***We are exposed to various risks from our regulatory environment, including being subject to potentially inconsistent or conflicting laws and regulations in the jurisdictions in which we operate, international trade-related disputes and compliance costs, which may adversely impact our reputation, financial condition and results of operations.***

We are subject to risks related to new, different, inconsistent, or even conflicting laws, rules, and regulations that may be enacted by legislative or executive bodies and/or regulatory agencies in the countries where we operate; disagreements or disputes related to international trade; and the interpretation and application of laws, rules, and regulations. As a public company with global operations, we are subject to the laws of multiple jurisdictions and the rules and regulations of various governing bodies, including those related to health and safety, import and export controls, financial and other disclosures, accounting standards, corporate governance, public procurement and public funding, environment (including those relating to sustainability, carbon emissions and climate change concerns), privacy, anti-corruption, such as the Foreign Corrupt Practices Act and other local laws prohibiting corrupt payments to governmental officials or customers, conflict minerals or other social responsibility legislation, employment practices, immigration or travel regulations and antitrust regulations, among others. Each of these laws, rules and regulations imposes costs on our business, including financial costs and potential diversion of our management's attention. There have been, and may continue to be, instances where we fail to ensure full compliance with all of the laws, rules and regulations to which we are subject. These instances present risks to our business, including potential fines, restrictions on our actions and reputational damage. The volume of changes to such laws, rules and regulations may increase in the countries where we operate.

Changes in or ambiguous interpretations of laws, regulations and standards, and the speed with which new regulations may be enacted and come into effect, may create uncertainty regarding compliance matters or instances where we may not be in full compliance. Efforts to comply with new and changing regulations have resulted in, and are likely to continue to result in, increased administrative expenses and diversion of management's time and attention from revenue-generating activities to compliance activities. If we are found by a court or regulatory agency not to be in compliance with laws and regulations, our reputation, business, financial condition and/or results of operations could be adversely affected, we may be disqualified or barred from participating in certain activities and we may be forced to modify our operations to achieve full compliance.

***Changes in taxation or adverse tax rulings could adversely affect our results of operations.***

We operate in many foreign countries and are subject to taxation at various rates and audit by multiple taxing authorities. Our results of operations could be affected by tax audits, changes in tax rates, changes in laws and regulations governing the calculation, location and taxation of earned profit, changes in laws and regulations affecting our ability to realize deferred tax assets on our balance sheet and changes in laws and regulations relating to the repatriation of cash into the U.S. Each quarter, we forecast our tax liability based on our forecast of our performance for the year in each tax jurisdiction. If our performance forecast changes, our forecasted tax liability would also likely change, perhaps materially.

We have undertaken, and expect to continue to undertake, complex internal reorganizations of our foreign subsidiaries in order to rationalize and streamline our foreign operations, focus our management efforts on certain local opportunities and take advantage of favorable business conditions in certain localities. These or any future reorganizations could result in adverse tax consequences in one or more jurisdictions, which could adversely impact our profitability from foreign operations and result in a material reduction in our results of operations.

Various jurisdictions in which we operate are considering changes to, or have already changed, their tax laws. For example, the OECD introduced the Base Erosion and Profit Shifting 2.0 project that seeks to impose a global minimum income tax rate of 15%. Any tax reform adopted in any foreign jurisdiction may exacerbate the risks described above and cause our corporate tax rate to increase.

***We receive government incentives, grants, and subsidies that are subject to conditions, reporting requirements, and compliance obligations, and failure to satisfy these requirements could result in the reduction, termination, or clawback of benefits, as well as potential penalties or reputational harm, any of which could adversely affect our business, financial condition, and results of operations.***

From time to time, we may receive and enter agreements for grants, subsidies, loans, tax arrangements and other incentives from national, state and local governments in jurisdictions throughout the world designed to encourage us to establish, maintain or increase our investment, research and development and production activities in those jurisdictions. Our future business plans are impacted by obtaining these government incentives, and they typically require us to achieve or maintain certain levels of investment, capital spending, employment, technology deployment or development milestones, construction or production milestones, or research and development activities to qualify for such incentives or could restrict us from undertaking certain

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

activities. Compliance with these requirements may add complexity to our operations and increase our costs, and a failure to comply could result in cancellation of agreements or transactions, investigations, civil and criminal penalties, forfeiture of profits, reduction, termination or clawback of any funding, suspension or debarment from doing business with the government, or other penalties, any of which could have a material and adverse effect on our business, financial condition and results of operations. For example, we have entered into a direct funding agreement with the U.S. Department of Commerce to receive a grant under the U.S. CHIPS and Science Act of 2022. We may be unable to successfully achieve the milestones and ancillary requirements to qualify for these incentives or such incentives may otherwise be withheld. In addition, incentives may be subject to ongoing compliance "guardrails," audit rights, domestic sourcing or workforce requirements, and restrictions on certain activities or transactions. The timing of any reimbursements or funding may not align with our capital spending or operating needs, and we may be required to fund substantial costs in advance of receiving any benefits (if received at all). We also may be unable to obtain future incentives, which may put us at a disadvantage against competitors, especially foreign competitors that may benefit from such incentives in the countries in which they are headquartered.

**Risks Related to Our Indebtedness**

***We have a substantial amount of indebtedness and may in the future incur substantially more debt, each of which could adversely affect our ability to obtain financing in the future and react to changes in our business.***

As of December 31, 2025, we had an aggregate principal amount of $3.7 billion of indebtedness outstanding, including the $0.5 billion from our senior secured term loan facility due 2029 (the "Term Loan Facility"), $1.6 billion aggregate principal amount of the 4.75% senior secured notes due April 15, 2029, $1.7 billion aggregate principal amount of the 5.95% senior unsecured notes due June 15, 2030, our 4.375% senior unsecured notes due April 15, 2028, and our 3.625% senior unsecured notes due May 1, 2029 (collectively, the "Notes"). In addition, we have approximately $575.0 million of unutilized capacity under our senior secured revolving credit facility due 2027 (the "Revolving Facility"). We refer to the Term Loan Facility and the Revolving Facility as the "Credit Facilities". The credit agreements that govern the Credit Facilities are referred to collectively as the "Amended Credit Agreement". Further, we may incur significant additional secured and unsecured indebtedness in the future.

Although the indentures governing the Notes (the "Indentures") and the Amended Credit Agreement restrict our ability to incur additional indebtedness, the restrictions have a number of significant qualifications and exceptions. For example, the Amended Credit Agreement provides that we can request additional loans and commitments up to the greater of $1.1 billion or 100% of our EBITDA, as well as additional amounts if our secured net leverage ratio is less than a specified ratio. Further, these restrictions do not prevent us from incurring monetary obligations that do not constitute indebtedness. If we add new indebtedness and other monetary obligations to our current debt levels, the related risks that we now face would intensify.

Our debt could have important consequences, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• requiring a substantial portion of our cash flow to be dedicated to debt service payments instead of other purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increasing our vulnerability to adverse changes in general economic, industry and competitive conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exposing us to increased interest expense for borrowings with variable interest rates, including borrowings under the Credit Facilities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• placing us at a disadvantage compared to other, less leveraged competitors or competitors with comparable debt having more favorable terms.

Higher or sustained interest rates and tighter credit market conditions could increase our borrowing costs, reduce refinancing flexibility and limit access to capital. Any downgrade in our credit profile, or reduced lender or investor appetite for debt financing, could further increase our cost of capital and adversely affect our liquidity and financial condition.

***We may be unable to generate sufficient cash to service our indebtedness and may be forced to take other actions, which may not be successful, to satisfy our obligations under our indebtedness.***

We may be unable to maintain sufficient cash flow from operating activities to permit us to pay the principal of, premium, if any, and interest on our indebtedness. Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance and the condition of the capital markets, which are subject to prevailing economic, industry and competitive conditions, as well as many financial, business, legislative, political, regulatory and other factors beyond our control. If our cash flow and capital resources are insufficient to fund our debt service obligations, we could

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

face substantial liquidity problems, be forced to reduce or delay investments and capital expenditures, dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance our indebtedness, any of which could have a material adverse effect on our business, financial position and results of operations. In addition, the level and quality of our earnings, operations, business and management, among other things, will impact the determination of our credit ratings. Any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis may result in a decrease in the ratings assigned to us by the ratings agencies, which may negatively impact our access to the debt capital markets and increase our cost of borrowing. In addition, we may be unable to maintain the current creditworthiness or prospective credit rating of the Company. Any actual or anticipated changes or downgrades in such credit rating or disruptions in the global financial markets may have a negative impact on our liquidity, capital position or access to capital markets and affect our ability to obtain any future required financing on acceptable terms or at all.

Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. We may not be able to implement any refinancing on commercially reasonable terms or at all and, even if successful, a refinancing may not allow us to meet our scheduled debt service obligations. The agreements governing our indebtedness restrict our ability to dispose of assets and use the proceeds of such dispositions, and we may be unable to consummate any dispositions or generate proceeds sufficient to meet our debt service obligations.

If we cannot make scheduled payments on our debt, holders of the Notes and lenders under the Credit Facilities could declare all outstanding principal and interest to be due and payable, the lenders under the Revolving Facility could terminate their commitments to advance further loans, our secured lenders could foreclose against the assets securing their borrowings and we could be forced into bankruptcy or liquidation.

***The terms of the Amended Credit Agreement and the Indentures may restrict our operations, particularly our ability to respond to changes or raise additional funds.***

The Amended Credit Agreement contains restrictive covenants that impose significant operating and financial restrictions that may limit our and our restricted subsidiaries' ability to take actions that may be in our long-term best interest, including restrictions on our and our restricted subsidiaries' ability to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• incur additional indebtedness and guarantee indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay dividends or make other distributions in respect of, or repurchase or redeem, capital stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prepay, redeem or repurchase certain debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• make investments, loans, advances and acquisitions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engage in sale-leaseback or hedging transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• create liens on, sell or otherwise dispose of assets, including capital stock of our subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into transactions with affiliates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into agreements that restrict the ability to create liens, pay dividends or make loan repayments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• alter the businesses we conduct; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• merge or sell all or substantially all of our assets or incur a change of control in our capital stock ownership.

Also, the Indentures contain limited covenants, such as a covenant restricting our ability and certain of our subsidiaries' ability to incur certain debt secured by liens, engage in sale-leaseback and incur additional indebtedness by any restricted subsidiary.

In addition, the restrictive covenants under the credit agreement governing the Revolving Facility may, depending on the amount of revolving borrowings, unreimbursed letter of credit drawings and undrawn letters of credit, require us to maintain a secured net leverage ratio, which we may be unable to meet. Our failure to comply with these covenants could result in the acceleration of some or all of our indebtedness, which could lead to bankruptcy, reorganization or insolvency.

**Risks Related to Owning our Common Stock**

***The price of our common stock has been and may remain volatile.***

The price of our common stock has been volatile. In 2025, the closing price of our stock on The Nasdaq Global Select Market ("Nasdaq") ranged from a low of $62.92 to a high of $109.53, and, as in past years, the price of our common stock may show even greater volatility in the future. The trading price of our common stock is subject to significant volatility in response to numerous factors, many of which are beyond our control or may be unrelated to our operating results, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes to our financial guidance, as well as potential decreased confidence in any guidance we do provide;

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in global economic and geopolitical conditions, including those resulting from trade tensions, rising inflation, and fluctuations in foreign currency exchange and interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to meet the expectations of securities analysts, which may vary significantly from our actual results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in financial estimates by securities analysts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• press releases or announcements by, or changes in market values of, comparable companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• high volatility in price and volume in the markets for high-technology stocks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public perception of equity values of publicly traded companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in our results of operations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other risks and uncertainties described in this Annual Report on Form 10-K and in our other filings with the SEC.

Fluctuations in our results of operations could cause our stock price to decline significantly. Future decreases in our stock price may adversely impact our ability to raise sufficient additional capital in the future, if needed.

***We may decrease or discontinue cash dividends and may never adopt a new program to repurchase our shares of common stock.***

Future payments of quarterly dividends and any future repurchases of shares of our common stock are subject to capital availability and periodic determinations by our Board of Directors that they are in the best interest of our stockholders and comply with all laws and applicable agreements. Future dividends and any future share repurchases may be affected by, among other factors, potential capital requirements for acquisitions and the funding of our research and development activities; legal risks; changes in federal and state income tax laws or corporate laws; contractual restrictions, such as financial or operating covenants in our debt arrangements; availability of domestic cash flow; and changes to our business model. The amounts of our dividend payments may change from time to time, and we may decide at any time to reduce, suspend or discontinue the payment of dividends. A reduction, suspension or discontinuation of our dividend payments or the lack of a share repurchase program could have a negative effect on the price of our common stock and may harm our reputation.

***Provisions in our charter documents and Delaware law may delay or prevent an acquisition of us, which could decrease the value of our shares.***

Our certificate of incorporation, our by-laws and Delaware law contain provisions that could make it harder for a third party to acquire us without the consent of our board of directors. These provisions include limitations on actions by written consent of our stockholders.

Our certificate of incorporation makes us subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits publicly held Delaware corporations from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. This provision could discourage parties from bidding for our shares of common stock and could, as a result, reduce the likelihood of an increase in the price of our common stock that would otherwise occur if a bidder sought to buy our common stock.

Our certificate of incorporation authorizes our Board of Directors to issue, without further stockholder approval, up to 5,000,000 shares of preferred stock in one or more series and to fix and designate the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, redemption rights and liquidation preferences. The holders of any shares of preferred stock could have preferences over the holders of our common stock with respect to dividends and liquidation rights. Any issuance of preferred stock may have the effect of delaying, deterring or preventing a change in control. Any issuance of preferred stock could decrease the amount of earnings and assets available for distribution to the holders of common stock and could adversely affect the rights and powers, including voting rights, of the holders of common stock. The issuance of preferred stock could have the effect of decreasing the market price of our common stock.

**General Risks**

***Competition from new or existing companies could harm our financial condition, results of operations and cash flow.***

We operate in a highly competitive, global industry. We face many domestic and international competitors, some of which have substantially greater manufacturing, financial, research and development and marketing resources than we do. In addition, some of our competitors may have better-established customer relationships than we do, which may enable them to have their products specified for use more frequently and more quickly by these customers. We also face competition from smaller,

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

regional companies that focus on serving customers in their regions. Further, customers continually evaluate the benefits of internal manufacturing versus outsourcing, and a customer's decision to internally manufacture products that we provide may negatively impact us. If we are unable to maintain our competitive position, we could experience downward pressure on prices, fewer customer orders, reduced margins, the inability to take advantage of new business opportunities and a loss of market share, any of which could have a material adverse effect on our results of operations. Further, we expect that existing and new competitors will improve their products and introduce new products with enhanced performance characteristics. The introduction of new products or more efficient production of existing products by competitors could diminish our market share and increase pricing pressure on our products.

Our competitors include companies outside of the U.S., including companies in countries where foreign governments seek to build a domestic-centric semiconductor ecosystem. From time to time, governments around the world may provide incentives or make other investments that could benefit and give competitive advantages to our competitors. Government incentives may not be available to us on acceptable terms or at all. If our competitors can benefit from such government incentives and we cannot, it could strengthen our competitors' relative position and have a material adverse effect on our business.

***We may acquire other businesses, form joint ventures or divest businesses, any of which could negatively affect our financial performance.***

We intend to continue to engage in business combinations, acquisitions, joint ventures, investments, divestitures or other types of collaborations to (1) address gaps in our product offerings, (2) adjust our business and product portfolio to meet our ongoing strategic objectives, (3) diversify into new and complementary markets, (4) increase our scale or (5) accomplish other strategic objectives. These transactions involve numerous risks to our business, financial condition and operating results, including but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulty in identifying suitable acquisition candidates and completing transactions at appropriate valuations, in a timely manner, on a cost-effective basis or at all, due to substantial competition for acquisition targets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inability to successfully integrate any acquired businesses into our business operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to realize the anticipated synergies or other benefits of any such transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• entry into markets in which we have limited or no prior experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• finding acquirors and obtaining adequate value for businesses that no longer meet our strategic objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties surrounding the disentanglement of a divested business, including the diversion of resources away from our business operations to address such matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inability to complete proposed or pending transactions due to factors such as the failure or inability to obtain regulatory or other approvals, which may be exacerbated by the recent, more aggressive regulatory approaches to merger control globally, such as the July 19, 2023 joint statement of antitrust policy and final rules published on October 10, 2024 concerning changes to the premerger notification process under the Hart-Scott-Rodino Act of 1976 by the Department of Justice and Federal Trade Commission and the April 15, 2023 Provisions on the Review of Concentrations of Undertakings issued by China's State Administration for Market Regulation, among others;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• requirements imposed by government regulators in connection with their review of a transaction, which may include, among other things, divestitures and restrictions on the conduct of our existing business or the acquired business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• undertaking multiple transactions at the same time in order to take advantage of acquisition or divestiture opportunities that do arise, which could strain our ability to effectively execute and integrate such transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• diversion of management's attention from our day-to-day business due to dedication of significant management resources to such transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• employee uncertainty and lack of focus during the integration process that may also disrupt our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risk of litigation or claims associated with a proposed or completed transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges associated with managing new, more diverse and more widespread operations, projects and people, potentially located in regions where we have not historically conducted or operated our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dependence on unfamiliar or less secure supply chains and inefficient scale of the acquired entity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increasing costs of performing due diligence to meet the expectations of investors and government regulators;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• despite our due diligence, we could assume unknown, underestimated or contingent liabilities, such as potential environmental, health and safety liabilities, any of which could lead to costly litigation or mitigation actions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an acquired technology or product may have inadequate or invalid intellectual property protection or may be subject to claims of infringement by a third party, which may result in claims for damages and lower than anticipated revenue;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negative effects on our reported results of operations from dilutive results from operations and/or from future potential impairment of acquired assets, including goodwill, related to acquisitions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an acquired company may have inadequate or ineffective internal controls over financial reporting, disclosure controls and procedures, cybersecurity, privacy, environmental, health and safety, anti-bribery, anti-corruption, human resource

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

or other policies or practices, which may require unexpected or additional integration, mitigation and remediation costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reductions in cash or increases in debt to finance transactions, which reduce the cash flow available for general corporate or other purposes, including repayment of existing debt, share repurchases and dividends; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties in retaining key employees or customers of an acquired business.

***Climate change may have a long-term impact on our business, including by causing disruptions to our operations which may result in decreased revenue and cash flows.***

There are inherent climate-related risks wherever our business is conducted. Changes in market dynamics, stakeholder expectations, local, national and international climate change policies, and the frequency and intensity of extreme weather events on critical infrastructure in the U.S. and abroad, all have the potential to disrupt our business and operations. Such events could result in a significant increase in our costs and expenses and harm our future revenue, cash flows and financial performance. In addition to physical risks, evolving climate-related and sustainability reporting regimes in jurisdictions where we operate (including state and international regimes) may increase compliance costs, require new data collection and assurance processes across our value chain and expose us to reputational harm or litigation if our disclosures, targets or progress are challenged. Global climate change is resulting in, and may continue to result, in certain natural disasters and adverse weather events, such as drought, wildfires, severe storms, sea-level rise and flooding, occurring more frequently or with greater intensity, which could cause business disruptions and adverse impacts where we operate.

**Risk management and strategy** 

As a key supplier in the semiconductor ecosystem, security and risk management of our technology systems and processes is critical to ensuring our ability to serve our customers without interruption.

*Management of Cybersecurity Risks* 

Our management of cybersecurity risks is integrated into our Company-wide enterprise risk management program. As part of this process, our risk management team works closely with our IT department to identify and evaluate potential cybersecurity risks to the Company and to develop controls to mitigate and protect against those risks.

Each quarter, our Chief Information Security Officer ("CISO") presents an overview of the Company's cybersecurity risk landscape to our Enterprise Risk Management Committee, which includes our Executive Leadership Team and Vice President, Internal Audit. In addition, our CISO Council, which includes our CISO and our Chief Information and Digital Officer ("CIDO"), holds meetings with our Executive Leadership Team on a quarterly basis to review these cybersecurity risks and mitigation measures in further detail.

Our cybersecurity risk management program is aligned with the National Institute of Standards and Technology Cybersecurity Framework. We identify key assets that are critical to our business and assess potential cyber threats and vulnerabilities associated with those assets and the operations they enable. Following that assessment, we implement strategies and design controls to manage those risks. For example, we use single sign-on to limit access to our networks and multi-factor authentication to verify users' identities. We also continuously monitor our systems and networks to protect against internal and external threat actors. We have policies and procedures in place, such as our Privileged Access Management process, to limit and control access to our confidential information by our vendors and other third parties. We also conduct due diligence and reviews of cybersecurity policies of third parties that access our systems or data. Additionally, we are focused on segregating our manufacturing processes from the Company's other networks to minimize the risk of interruptions to our manufacturing operations resulting from cyber breaches. To increase our employees' vigilance of cybersecurity risks and educate them on best practices relating to those risks, we conduct quarterly awareness sessions, annual trainings and monthly phishing campaigns.

*Engagement of Third Parties* 

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

Given the complex and evolving nature of cybersecurity threats, the Company periodically engages third parties to assist us in evaluating our security vulnerabilities and developing and maintaining effective cybersecurity risk management. Partnering with third parties enables us to leverage specialized knowledge and insights, ensuring our cybersecurity strategies and processes are well-designed and effective. For example, in 2023, we engaged a global law firm to conduct an external assessment of our cybersecurity governance framework and processes and provide recommendations to improve our cybersecurity readiness and posture. Each year, to prevent and mitigate cybersecurity-related risks, we engage independent cybersecurity specialists to conduct comprehensive threat and vulnerability assessments, such as penetration testing, social engineering evaluations and structured tabletop exercises. Their findings help validate our controls, test our response capabilities and inform strategies our strategies to manage and reduce enterprise cybersecurity risk.

*Oversight of Third-Party Risk*

We are aware of the cybersecurity risks associated with engaging third-party service providers. To mitigate such risks, we conduct security assessments of high-risk third-party providers before engagement and maintain ongoing monitoring to ensure compliance with our cybersecurity standards. The monitoring includes ongoing assessments by our security engineers. This approach is designed to mitigate risks related to data breaches or other security incidents originating from third parties.

*Risks from Cybersecurity Threats*

The Company's information and operational technology systems and its third-party providers' systems have been, and will likely continue to be, subject to cybersecurity threats, such as computer viruses or other malicious codes, ransomware, unauthorized access attempts, business email compromise, cyber extortion, denial of service attacks, phishing, social engineering, hacking and other cyberattacks attempting to exploit vulnerabilities.

To date, the Company is not aware that its business or operations have been, or are reasonably likely to be, materially impacted by these cyberattacks. However, the Company's security efforts and the efforts of its third-party providers may not prevent or timely detect attacks and resulting breaches or breakdowns of the Company's, or its third-party service providers', databases or systems.

**Governance** 

*Board of Directors' Oversight* 

The Audit and Finance Committee (the "Audit and Finance Committee") of our Board of Directors is responsible for reviewing and monitoring general IT and cybersecurity matters, including related risks, and reporting to the Board its determinations, actions and recommendations related thereto. Our Audit and Finance Committee is composed of independent directors with extensive executive leadership and risk management experience. Our CISO, together with our CIDO, provide quarterly updates to our Audit and Finance Committee regarding the cybersecurity risk landscape, specific risks affecting the Company and solutions to mitigate those risks, and legal and regulatory requirements relating to cybersecurity. These updates assist the Board in performing its oversight and risk management function. In addition, the full Board receives an annual report on cybersecurity directly from the CISO.

*Management's Role Managing Risk* 

Our CISO is responsible for the implementation, operation and monitoring of our cybersecurity risk management program. Our current CISO, who reports to our CIDO, has over 20 years of experience managing the IT and cybersecurity operations within large, global organizations. His extensive experience assessing and mitigating cybersecurity risk, implementing governance structures and developing employee training programs is critical in developing and executing our cybersecurity strategies.

*Monitoring of Cybersecurity Incidents* 

Our Cybersecurity Incident Response Plan establishes how we monitor and respond to cybersecurity incidents impacting our environment. The CISO works closely with members of our Executive Leadership Team and his cybersecurity team to monitor the prevention, detection, mitigation, and remediation of cybersecurity incidents. We engage a third-party managed security services provider (MSSP) to provide 24/7 continuous monitoring of the Company's IT and operational technology environments for potential cybersecurity incidents. In the event such an incident is identified by our MSSP or any of our employees, our cybersecurity team assigns it a severity classification and escalates the incident accordingly. Depending on the severity of the incident, certain key personnel are notified and work together to further investigate the incident and take actions to respond, which may include engaging with external specialists, regulatory authorities and our cybersecurity insurance carrier. The CISO receives regular updates on all incidents and incident responses, which the CISO shares with our Executive

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

Leadership Team on a weekly basis. Our cybersecurity team conducts a post-incident review of all major cybersecurity incidents, which review includes identification of vulnerabilities, assessment of the incident's impact on the Company and recommendations to help prevent similar incidents in the future.

See "Item 1A. Risk Factors" for a more detailed description of the cybersecurity risks we face.

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

**Item 2. Properties.**

We own and lease facilities for manufacturing, distribution, technical support, sales, service, repair, and general administrative purposes primarily located in the United States, Canada, Taiwan, South Korea, Japan, China, Singapore, Malaysia, Germany, France and Israel. As of December 31, 2025, we owned and leased approximately 3.7 million square feet and 1.9 million square feet of space, respectively, across 72 owned and 31 leased properties. Our principal executive offices are located in Billerica, Massachusetts. Because of the interrelation of our operations, properties in certain geographical locations may be attributable to multiple reporting segments. We believe that our facilities are well-maintained and suitable for their respective operations. We regularly assess the size, capability and location of our global infrastructure and periodically make adjustments based on these assessments.

**Item 3. Legal Proceedings.**

We are, from time-to-time, involved in various claims, proceedings and lawsuits relating to our business, employees, intellectual property and other matters. The outcomes of these matters are not within our complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, that could require significant expenditures or result in lost revenues. We record a liability for these matters when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. There is judgment required in the determination of the likelihood of outcome, and if necessary determination of the estimate or range of potential outcomes. Based on the current information, the Company does not believe any known matters have a reasonable possibility of a material amount for litigation or other contingencies related to legal proceedings.

**Item 4. Mine Safety Disclosures.**

***Issuer Purchases of Equity Securities***

The Company does not have a publicly announced stock repurchase program and we did not repurchase any equity securities during the year ended December 31, 2025.

The Company issues common stock awards under its equity incentive plans. In the consolidated financial statements, the Company treats shares of common stock withheld for tax purposes on behalf of its employees in connection with the vesting or exercise of the awards as common stock repurchases because they reduce the number of shares that would have been issued upon vesting or exercise. These withheld shares of common stock are not considered common stock repurchases pursuant to a Board-authorized common stock repurchase plan.

Our business is organized and operated in two operating segments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ The Materials Solutions segment, or MS, provides materials-based solutions, such as chemical vapor and atomic layer deposition materials, chemical mechanical planarization ("CMP") slurries and pads, ion implantation specialty gases, formulated etch and clean materials, and other specialty materials that enable our customers to achieve better device performance and faster time to yield, while providing for lower total cost of ownership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ The Advanced Purity Solutions segment, or APS, offers filtration, purification and contamination-control solutions that improve customers' yield, device reliability and cost by ensuring the purity of critical liquid chemistries and gases and the cleanliness of wafers and other substrates used throughout semiconductor manufacturing processes, the semiconductor ecosystem and other high-technology industries.

Our complementary capabilities enable co-optimized, integrated solutions that improve device performance, lower cost of ownership and accelerate time to market. We address complex manufacturing challenges across deposition, CMP and post-CMP modules with solutions including advanced deposition materials, CMP slurries, pads and post-CMP cleaning chemistries (each from our MS segment), and CMP slurry filters, high-purity packaging and fluid monitoring systems (each from our APS segment). As leading semiconductor manufacturers implement molybdenum into advanced nodes, Entegris is uniquely positioned to support this transition and to solve challenges associated with integrating a new material through our expertise and solutions in precursors, deposition, etch, CMP consumables and contamination control.

**Global Trade Environment**

Recent and continuing developments in U.S. and foreign trade policy have heightened global trade tensions and sparked significant uncertainty in macroeconomic and geopolitical environments, particularly with respect to China. The nature of our global business exposes us to risks associated with trade conflicts between the U.S. and its trading partners. Additionally, our manufacturing operations rely on a global supply chain to manufacture our products, including, in some instances, raw materials from China. The recent tariffs and other similar trade policies may increase our sourcing and manufacturing costs, force us to find alternative suppliers, or result in manufacturing and delivery delays. As a result, we may face a reduction in the demand for, and in the competitiveness of, our products, harm to our relationships with our customers, and decreased profitability. These issues may be exacerbated by the overall macroeconomic uncertainty stemming from current trade tensions which may slow economic growth and negatively impact the demand for products containing semiconductors, thereby decreasing the demand for our products.

Our strategy has been, and will continue to be, to build a resilient and robust supply chain and a global manufacturing footprint near our customers. While this strategy should mitigate the Company from financial and operational impacts of a volatile trade environment in the medium to long term, our business could still be impacted by sudden changes in trade policy in the near term, particularly, for example, our products manufactured in the United States and sold to customers located in China. Given the dynamic nature of this situation, the direct and indirect impact to our customers and our business is difficult to quantify; however, we will continue to closely monitor this evolving situation, further leverage our global footprint and regional supply chain, and explore additional options to mitigate this volatility.

**Recent Events** 

In January 2026, we completed an assessment of the useful lives of our property, plant and equipment and adjusted the estimated useful lives of certain property, plant and equipment to more closely reflect the expected economic lives of these assets. These adjustments followed an analysis of our actual usage of assets, including the technological and physical obsolescence of these assets, our ability to continue to use equipment, historical usage trends, and anticipated capital plans and technology roadmaps, as well as industry trends and practices. Based on this analysis, we determined that the increase in useful lives was warranted and consistent with the Company's historical and anticipated use of these assets. The updated estimated useful lives of certain assets for financial reporting purposes are as follows: buildings and improvements, 5 to 35 years increased to 5 to 40 years; manufacturing equipment, 5 to 10 years increased 5 to 14 years; canister and cylinder 3 to 12 years increased to 3 to 19 years; molds 3 to 5 years increased to 3 to 9 years and lab equipment, 3 to 8 years increased to 3 to 9 years.

This change in accounting estimate is effective beginning in fiscal year 2026 and is applied prospectively to the assets on our balance sheet as of December 31, 2025 and to future asset purchases. Based on the carrying amount of the assets included in property, plant and equipment, net in our Consolidated Balance Sheet as of December 31, 2025, we expect total depreciation expense in 2026 to be reduced by $72.9 million. We expect this change will result in an increase in gross margin of approximately $52.4 million, a decrease in ER&D expenses of approximately $11.4 million and a decrease in ending inventory values of $9.1 million.

**Critical Accounting Policies and Estimates**

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

Management's discussion and analysis of financial condition and results of operations are based upon the Company's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The preparation of these consolidated financial statements requires the Company to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. At each balance sheet date, management evaluates its estimates, including, but not limited to, those related to long-lived assets (property, plant and equipment, and identified intangible assets), goodwill and income taxes. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Management's utilization of different judgments or estimates could result in material differences in the amount and timing of the Company's results of operations for any period. In addition, actual results could be different from the Company's current estimates, possibly resulting in increased future charges to earnings.

Our critical accounting policies that are most significantly affected by estimates, assumptions and judgments used in the preparation of the Company's consolidated financial statements relate to business acquisitions and are discussed below. See Note 1 to the Company's consolidated financial statements for additional information about the Company's other significant accounting policies.

**Goodwill**

Goodwill is tested for impairment annually as of August 31. If circumstances change during interim periods between annual tests that would more likely than not reduce the fair value of a reporting unit below its carrying value, the Company will test goodwill for impairment. Factors that would necessitate an interim goodwill impairment assessment include a sustained decline in the Company's stock price, effects on a reporting unit such as a change in the composition or carrying amounts of its net assets, prolonged negative industry or economic trends, or significant under-performance relative to expected, historical or projected future operating results. We allocate goodwill to reporting units at the time of acquisition or when there is a change in the reporting structure and base that allocation on which reporting units will benefit from the acquired assets and liabilities. Reporting units are defined as operating segments or one level below an operating segment, referred to as a component. The Company has defined its reporting units as its operating segments, MS and APS as disclosed in Note 20 to our consolidated financial statements.

Management uses judgment to determine whether to use a qualitative analysis or a quantitative fair value measurement for its goodwill impairment testing. For the year ended December 31, 2025, the Company determined to utilize a qualitative analysis for the APS reporting unit and a quantitative analysis for the MS reporting unit. The MS reporting unit's fair value was estimated using an equal weighting of the income and market valuation approaches. The Company's fair value measurement approach combines the income and market valuation techniques for each of the Company's reporting units that carry goodwill. These valuation techniques use estimates and assumptions including, but not limited to, the determination of appropriate market comparable, projected future revenue growth and gross margins, the discount rate reflecting the risk inherent in future cash flows, the terminal growth rate, and projected future economic and market conditions. Based upon a sensitivity analysis the Company performed, a 50 basis point change in the projected compound annual revenue growth rate, gross margins, discount rate, or terminal growth rate assumption would not result in an impairment in the MS reporting unit.

If a reporting unit fails the quantitative impairment test, impairment expense is immediately recorded as the difference between the reporting unit's fair value and carrying value not to exceed the amount of goodwill recorded. We recorded no impairment charges related to goodwill during the fiscal years ended December 31, 2025 and 2024. Adverse changes in the future could reduce the underlying cash flows used to estimate the reporting unit fair values and could result in a further decrease in fair value that could trigger a future impairment charge of the goodwill balance.

**Net sales** For 2025, net sales were $3,196.6 million, decreased by $44.6 million, or 1%, from 2024. An analysis of the factors underlying the decrease in net sales is presented in the following table:

---

| | |
|:---|:---|
| *<u>(In millions)</u>* |  |
| Net sales in 2024 | $3241.2 |
| Decrease associated with divestiture | (33.9) |
| Decrease mainly associated with volume | (14.2) |
| Increase associated with effect of foreign currency translation | 3.5 |
| Net sales in 2025 | $3196.6 |

---

As described in the table above, the decrease in net sales was primarily attributable to (i) the absence of $33.9 million in sales associated with the divested PIM business and (ii) a reduction of $14.2 million of sales mainly due to decreased semiconductor market demand compared to the year ago period ended December 31, 2024. These sales were partially offset by an increase of $3.5 million of sales attributable to favorable foreign currency translation effects, primarily related to the strengthening of the Taiwanese dollar, Japanese yen and euro relative to the U.S. dollar compared to the year ago period ended December 31, 2024.

Sales percentage on a geographic basis for 2025 and 2024 and the percentage increase (decrease) in sales for 2025 compared to sales for 2024 were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Year ended** | **Year ended** | |
| | **December 31, 2025** | **December 31, 2024** | **Percentage increase (decrease) in sales** |
| North America | 18% | 21% | (16)% |
| Taiwan | 23% | 20% | 11% |
| China | 21% | 21% | (2)% |
| South Korea | 13% | 13% | 2% |
| Japan | 10% | 10% | 3% |
| Europe | 7% | 8% | (13)% |
| Southeast Asia | 8% | 7% | 10% |

---

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

The decrease in sales to customers in North America primarily relates to the absence of sales from the divested PIM business and from decreased demand for our MS and APS products. The increase in sales to customers in Taiwan primarily relates to increased demand for our MS and APS products. The decrease in sales to customers in China primarily relates to decreased demand for our APS products, partially offset by increased demand for our MS products. The increase in sales to customers in South Korea primarily relates to increased demand for our MS and APS products. The increase in sales to customers in Japan primarily relates to increased demand for our MS products, partially offset by decreased demand for our APS products. The decrease in sales to customers in Europe primarily relates to decreased demand for our MS and APS products. The increase in sales to customers in Southeast Asia primarily relates to increased demand for our MS and APS products.

**Gross margin** 

The following table sets forth gross margin as a percentage of net sales:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | **2024** | **Percentage point change** |
| Gross margin as a percentage of net sales: | 44.4% | 45.9% | (1.5) |

---

Gross margin decreased by 1.5% for 2025 compared to 2024. Gross margin decreased primarily due to plant performance and higher depreciation expense.

**Selling, general and administrative expenses** 

Selling, general and administrative ("SG&A") expenses consist primarily of payroll and related expenses for the sales and administrative staff, professional fees (including accounting, legal and technology costs and expenses), and sales and marketing costs. SG&A expenses for 2025 increased $4.0 million, or 1%, to $450.6 million from $446.6 million in 2024.

An analysis of the factors underlying the increase in SG&A expenses is presented in the following table:

---

| | |
|:---|:---|
| *<u>(In millions)</u>* |  |
| Selling, general and administrative expenses in 2024 | $446.6 |
| Restructuring costs, see Note 15 to the Company's Consolidated Financial Statements | 18.8 |
| Loss on sale of divested business in 2025 | 10.9 |
| Gain on sale of PIM business in 2024 | 4.3 |
| Impairment on long-lived assets in 2024, see Note 3 to the Company's Consolidated Financial Statements | (13.0) |
| Professional fees | (9.7) |
| Employee costs (excluding restructuring costs of $3.1 included in the line above) | (3.9) |
| Other decreases, net | (3.4) |
| Selling, general and administrative expenses in 2025 | $450.6 |

---

**Engineering, research and development expenses**

Engineering, research and development ("ER&D") expenses consist of expenses for the support of current product lines and the development of new products and manufacturing technologies. These expenses were $329.0 million in 2025 and $316.1 million in 2024.

An analysis of the factors underlying the increase in ER&D expenses is presented in the following table:

---

| | |
|:---|:---|
| *<u>(In millionss)</u>* |  |
| Engineering, research and development expense in 2024 | $316.1 |
| Depreciation expense | 4.7 |
| Project related costs | 4.0 |
| Restructuring costs, see Note 15 to the Company's consolidated financial statements | 3.1 |
| Other increases, net | 1.1 |
| Engineering, research and development expense in 2025 | $329.0 |

---

The Company's overall ER&D efforts will continue to focus on developing and improving its technology platforms to support the semiconductor ecosystem and identifying and developing products for new applications. The Company often works directly with its customers to address their needs.

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

**Amortization of intangible assets** Amortization of intangible assets was $184.4 million in 2025 compared to $190.1 million for 2024. The decrease primarily reflects the absence of amortization for certain identifiable intangible assets acquired in previous acquisitions that became fully amortized.

**Interest expense** Interest expense was $199.8 million in 2025 and $215.2 million in 2024. Interest expense includes interest associated with debt outstanding and the amortization of debt issuance costs associated with such borrowings. The decrease reflects lower interest expense related to lower average debt balances for the period due to repayments on the Company's outstanding debt.

**Interest income** Interest income was $7.9 million in 2025 and $7.3 million in 2024. The increase primarily reflects higher average cash balances at our foreign subsidiaries.

**Other expense, net** Other expense, net, was $9.4 million in 2025 compared to $4.0 million in 2024.

In 2025, other expense, net consisted mainly of loss of extinguishment of debt of $3.2 million associated with the repayments on the Company's senior secured term loan facility (see Note 9 to the Company's consolidated financial statements) and foreign currency transaction losses of $7.1 million.

In 2024, other expense, net consisted mainly of loss of extinguishment and modification of debt of $14.3 million associated with the repayments and the Third Amendment on the Company's senior secured term loan facility (see Note 9 to the Company's consolidated financial statements) and foreign currency transaction losses of $7.7 million, partially offset by a gain of $20.0 million related to the settlement of patent infringement litigation.

**Income tax expense** The Company recorded income tax expense of $18.0 million in 2025 compared to income tax expense of $28.3 million in 2024. The Company's effective tax rate was 7.1% in 2025 compared to an effective tax rate of 8.8% in 2024.

The decrease in the effective tax rate from 2024 to 2025 primarily relates to lower income and the release of unrecognized tax benefits resulting from the expiration of applicable statute of limitations. This benefit was partially offset by an increase in discrete tax expense recorded associated with share-based compensation and the enactment of the One Big Beautiful Bill Act.

**Net income** Net income was $235.6 million, or $1.55 per diluted share, in 2025 compared to net income of $292.8 million, or $1.93 per diluted share, in 2024. The decrease reflects the Company's aforementioned operating results described in greater detail above.

**Non-GAAP Financial Measures Information** The Company's consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States. The Company also utilizes certain non-GAAP financial measures as a complement to financial measures provided in accordance with GAAP in order to better assess and reflect trends affecting the Company's business and results of operations. See "Non-GAAP Information" included below in this section for additional detail, including the reconciliation of the Company's non-GAAP measures to the most directly comparable GAAP measures.

The Company's non-GAAP financial measures include Adjusted EBITDA and Adjusted Operating Income, together with related percentage changes, and Non-GAAP Earnings Per Share, or EPS.

| | | | |
|:---|:---|:---|:---|
| | **Year ended** | **Year ended** | |
| *<u>(In millions)</u>* | **December 31, 2025** | **December 31, 2024** | **Percent change** |
| Adjusted Operating Income | $680.9 | $743.0 | (8.4)% |
| Adjusted Operating Margin - as a % of net sales | 21.3% | 22.9% |  |
| Adjusted EBITDA | $886.2 | $931.1 | (4.8)% |
| Adjusted EBITDA - as a % of net sales | 27.7% | 28.7% |  |
| Non-GAAP EPS | $2.75 | $3.00 | (8.3)% |

---

The decreases in Adjusted Operating Income and Adjusted EBITDA in 2025 compared to 2024 are generally attributable to decreased gross profit and the absence of segment profit associated with the divested PIM business. The decrease in Non-GAAP EPS in 2025 compared to 2024 is primarily attributable to decreased gross profit and the absence of segment profit associated with the divested PIM business, partially offset by lower interest expense.

**Segment Analysis**

The Company reports its financial performance based on two reportable segments. See Note 20 to the consolidated financial statements for additional information on the Company's two segments.

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

The following table and discussion reflects the results of operations of the Company's two reportable segments for the years ended December 31, 2025, 2024 and 2023.

| Unallocated general and administrative expenses | $62.7 | $58.3 | $114.1 |

---

**<u>Materials Solutions (MS)</u>**

For 2025, MS net sales increased to $1,406.7 million, up from $1,400.1 million in 2024. The sales increase was driven by increased sales from CMP consumables, selective etch and deposition materials, partially offset by the absence of $33.9 million in prior-year sales from the divested PIM business and decreased sales from advanced materials products.

MS reported a segment profit of $276.6 million for 2025, down 3% compared to $286.2 million in 2024. The decrease was primarily associated with (1) the net impact related to the divested PIM business of $14.5 million (2) loss on sale of small, industrial specialty chemicals business of $10.9 million and (3) lower plant performance, partially offset with (4) a decrease of a $13.0 million of impairment charges related to the long-lived assets of the aforementioned industrial specialty chemicals business in 2024 and (5) higher sales volume.

**<u>Advanced Purity Solutions (APS)</u>**

For 2025, APS net sales decreased to $1,799.1 million, down 3% $1,850.2 million in 2024. The sales decrease was mainly due to a decline in facilities-based capital expenditure investments in the semiconductor industry, which led to decreased demand for our fluid handling products and FOUPs, partially offset by an increase in sales from gas and liquid filtration products.

APS reported a segment profit of $426.4 million for 2025, down 14% compared to $496.1 million in 2024. The decrease in APS's profit in 2025 was primarily due to lower sales, unfavorable plant performance, higher depreciation expense and higher restructuring costs of $21.9 million.

**<u>Unallocated general and administrative expenses</u>**

Unallocated general and administrative expenses for 2025 totaled $62.7 million compared to $58.3 million for 2024. The $4.4 million increase is primarily due to an increase in employee costs.

**Liquidity and Capital Resources**

We consider the following when assessing our liquidity and capital resources:

---

| | | |
|:---|:---|:---|
| *(In millions)* | **December 31, 2025** | **December 31, 2024** |
| Cash and cash equivalents | $360.4 | $329.2 |
| Working capital | 1149.6 | 1091.1 |
| Total debt | 3697.6 | 3981.1 |

---

The Company has historically financed its operations and capital requirements through cash flow from its operating activities, long-term loans, lease financing and borrowings under domestic and international short-term lines of credit.

Based on our analysis, we believe our existing balances of domestic cash and cash equivalents and our currently anticipated operating cash flows will be sufficient to meet our cash needs arising in the ordinary course of business for the next twelve months and for the longer term.

We may seek to take advantage of opportunities to raise additional capital through additional debt financing or through public or private sales of securities. If in the future our available liquidity is not sufficient to meet the Company's operating and debt service obligations as they come due, management would need to pursue alternative arrangements through additional equity or debt financing in order to meet the Company's cash requirements. There can be no assurance that any such financing would be available on commercially acceptable terms, or at all. During 2025, we did not experience difficulty accessing capital and credit

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

markets, but future volatility in the capital and credit markets may increase costs associated with issuing debt instruments or affect our ability to access those markets. In addition, it is possible that our ability to access the capital and credit markets could be limited at a time when we would like, or need, to do so, which could have an adverse impact on our ability to refinance maturing debt and/or react to changing economic and business conditions.

**In summary, our cash flows for each period were as follows:**

---

| | | |
|:---|:---|:---|
| *(In millions)* | **Year ended December 31, 2025** | **Year ended December 31, 2024** |
| Net cash provided by operating activities | $695.4 | $631.7 |
| Net cash used in investing activities | (300.8) | (67.1) |
| Net cash used in financing activities | (366.9) | (688.9) |
| Increase (decrease) in cash and cash equivalents | 31.2 | (127.7) |

---

**Operating activities**

Cash provided by operating activities is net income adjusted for certain non-cash items and changes in assets and liabilities.

Compared to 2024, the $63.7 million increase in cash provided by operating activities in 2025 was primarily driven by $101.6 million of changes in operating assets and liabilities, partially offset by a $37.9 million decrease of net income adjusted for non-cash reconciling items.

Changes in operating assets and liabilities were driven by changes in trade accounts and notes receivable, inventories and income taxes payable and refundable income taxes. The change for trade receivables was mainly due to timing of collections. The change for inventory was driven by decreased business activity. The change in income tax payable and refundable incomes taxes is primarily due to higher income tax payments.

**Investing activities**

Investing cash flows consist primarily of capital expenditures, cash used for acquisitions, proceeds and payments from sales of businesses and proceeds from sales of property and equipment.

Net cash used in investing activities was $300.8 million in 2025 compared to net cash provided by investing activities $67.1 million cash used in investing activities in 2024, primarily reflecting lower proceeds from divestitures of $257.5 million, partially offset by a $16.4 million decrease in capital expenditures and $8.2 million of proceeds from government incentives.

**Financing activities** 

Financing cash flows consist primarily of payment of dividends to stockholders, issuance and repayment of short-term and long-term debt, and proceeds from the sale of shares of common stock through employee equity incentive plans.

In 2025, there was $366.9 million of cash used in financing activities compared to $688.9 million cash used in financing activities in 2024. The change in 2025 was primarily due to decreased net debt activity of $323.8 million compared to the prior year.

The Company's total dividend payments were $60.8 million in 2025 compared to $60.6 million in 2024. The Company has paid a cash dividend in each quarter since the fourth quarter of 2017. On January 14, 2026, the Company's board of directors declared a quarterly cash dividend of $0.10 per share to be paid on February 18, 2026 to shareholders of record as of January 28, 2026.

Through December 31, 2025, the Company was in compliance with all applicable financial covenants included in the terms of its debt arrangements.

During the twelve months ended December 31, 2025, the Company borrowed and repaid $567.0 million under this Revolving Facility and no balance was outstanding at December 31, 2025.

The Company also has a line of credit with one bank that provides for borrowings of Japanese yen for the Company's Japanese subsidiary equivalent to an aggregate of approximately $6.4 million. There were no outstanding borrowings under this line of credit and no balance was outstanding at December 31, 2025.

Our cash and cash equivalents include cash on hand and highly-liquid debt securities with original maturities of three months or less, which are valued at cost and approximate fair value. We utilize a variety of funding strategies in an effort to ensure that our worldwide cash is available in the locations in which it is needed.

*Cash requirements*

We have cash requirements to support working capital needs, capital expenditures, business acquisitions, contractual obligations, commitments, principal and interest payments on debt and other liquidity requirements associated with our operations. We generally intend to use available cash and funds generated from our operations to meet these cash requirements, but, in the event that additional liquidity is required, we may also borrow under our Revolving Facility.

The following table summarizes our short and long-term cash requirements as of December 31, 2025:

| Total | $4885.3 | $419.1 | $4466.2 |

---

*Long-term debt and interest payments on long-term debt*. We have contractual obligations for principal and interest payments on our long-term debt. See Note 9 of the consolidated financials for additional information. Debt obligations are classified based on their stated maturity date, regardless of their classification on the Company's consolidated balance sheets. Interest projections on both variable and fixed rate long-term debt are based on interest rates effective as of December 31, 2025 and do not include $47.4 million for unamortized discounts and debt issuance costs.

*Capital purchase obligations*. We have capital purchase obligations that represent commitments for the construction or purchase of property, plant and equipment. They were not recorded as liabilities on the Company's consolidated balance sheet as of December 31, 2025, as the Company had not yet received the related goods or taken title to the property.

We expect capital expenditure spending to be approximately $250.0 million in 2026.

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

*Supply purchase obligations*. We have non-cancelable commitments, including take-or-pay contracts, that are not presented as capital purchase commitments above. They were not recorded as liabilities on the Company's consolidated balance sheet as of December 31, 2025, as the Company had not yet received the related goods or taken title to the property.

*Operating and financing lease commitments*. Commitments under operating and financing leases primarily relate to leasehold properties. See Note 13 of the consolidated financials for additional information.

*Income tax liabilities*. Of the tax liabilities included in the table above, $33.7 million relates to uncertain tax positions. We are unable to accurately predict when these amounts will be realized or released. However, it is reasonably possible that there could be significant changes to our unrecognized tax benefits in the next twelve months due to an unforeseeable event (such as a tax audit settlement). See Note 16 of the consolidated financials for additional information.

**New Accounting Pronouncements**

**Recently adopted accounting pronouncements** Refer to Note 1 to the Company's consolidated financial statements for a discussion of accounting pronouncements implemented in 2025.

**Recently issued accounting pronouncements** Refer to Note 1 of the Company's consolidated financial statements for a discussion of accounting pronouncements recently issued but not yet adopted.

**Non-GAAP Information** The Company's consolidated financial statements are prepared in conformity with GAAP.

The Company also utilizes certain non-GAAP financial measures as a complement to financial measures provided in accordance with GAAP in order to better assess and reflect trends affecting the Company's business and results of operations. These non-GAAP financial measures include Adjusted EBITDA and Adjusted Operating Income, together with related measures thereof, and Non-GAAP EPS, as well as certain other supplemental non-GAAP financial measures included in the discussion of the Company's financial results.

The non-GAAP financial measures exclude certain specific items ("Special Items"), including certain items related to mergers and acquisitions; divestitures; restructuring and severance charges; impairments of assets; refinancing; certain income tax items and other discrete adjustments related to non-recurring, unusual or unanticipated charges, expenses or gains. We evaluate Special Items on an individual basis. Our evaluation of whether to exclude a Special Item for purposes of determining our non-GAAP financial measures considers both the quantitative and qualitative aspects of the Special Item, including among other things (i) its nature, (ii) whether or not it relates to our ongoing business operations, and (iii) whether or not we expect it to occur as part of our normal business on a regular basis.

Adjusted EBITDA is defined by the Company as net income adjusted to exclude (1) equity in net loss of affiliates, (2) income tax expense, (3) interest expense, (4) interest income, (5) other expense, net, (6) depreciation, and (7) the impact of any Special Items. Adjusted Operating Income is defined by the Company as Adjusted EBITDA exclusive of the depreciation addback noted above. The Company also utilizes ratios of non-GAAP financial measures such as Adjusted EBITDA to Company net sales and Adjusted Operating Income to Company net sales (referred to as Adjusted EBITDA Margin and Adjusted Operating Margin, respectively).

Non-GAAP Net Income is defined by the Company as net income, adjusted to exclude the impact of any Special Items and the tax effect of the foregoing adjustments to net income, stated on a per share basis, divided by diluted weighted average shares outstanding. Non-GAAP EPS is defined as Non-GAAP Net Income divided by our diluted weighted-average shares outstanding.

The Company provides supplemental non-GAAP financial measures to help management and investors to better understand its business and believes these measures provide investors and analysts additional and meaningful information for the assessment of the Company's ongoing results. Management also uses these non-GAAP measures to assist in the evaluation of the performance of its business segments and to make operating decisions.

Management believes the Company's non-GAAP measures help indicate the Company's baseline performance before certain gains, losses or other charges that may not be indicative of the Company's business or future outlook and offer a useful view of business performance in that the measures provide a more consistent means of comparing performance. The Company believes the non-GAAP measures aid investors' overall understanding of the Company's results by providing a higher degree of transparency for such items and providing a level of disclosure that will help investors understand how management plans, measures and evaluates the Company's business performance. Management believes that the inclusion of non-GAAP measures provides greater consistency in its financial reporting from period-to-period and facilitates investors' understanding of the Company's historical operating trends by providing an additional basis for comparisons to prior periods.

Management uses Adjusted EBITDA and Adjusted Operating Income to assist it in evaluations of the Company's operating performance by excluding items that management does not consider as relevant in the results of its ongoing operations. Internally, these non-GAAP measures are used by management for planning and forecasting purposes, including the preparation

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

of internal budgets; for allocating resources to enhance financial performance; for evaluating the effectiveness of operational strategies; and for evaluating the Company's capacity to fund capital expenditures, secure financing and expand its business.

In addition, and as a consequence of the importance of these non-GAAP financial measures in managing its business, the Company's Board of Directors uses non-GAAP financial measures in the evaluation process to determine management compensation.

The Company believes that certain analysts and investors use Adjusted EBITDA, Adjusted Operating Income and Non-GAAP EPS as supplemental measures to evaluate the overall operating performance of firms in the Company's industry. Additionally, lenders or potential lenders use Adjusted EBITDA measures to evaluate the Company's creditworthiness.

The presentation of non-GAAP financial measures is not meant to be considered in isolation, as a substitute for, or superior to, financial measures or information provided in accordance with GAAP. Management strongly encourages investors to review the Company's consolidated financial statements in their entirety and to not rely on any single financial measure.

Management notes that the use of non-GAAP measures has limitations, including but not limited to:

First, non-GAAP financial measures are not standardized. Accordingly, the methodology used to produce the Company's non-GAAP financial measures is not computed under GAAP and may differ notably from the methodology used by other companies. For example, the Company's non-GAAP measure of Adjusted EBITDA may not be directly comparable to EBITDA or an Adjusted EBITDA measure reported by other companies.

Second, the Company's non-GAAP financial measures exclude items such as amortization and depreciation that are recurring. Amortization of intangibles and depreciation have been, and will continue to be for the foreseeable future, significant recurring expenses with an impact upon the Company's results of operations, notwithstanding the lack of immediate impact upon cash flows.

Third, there is no assurance that the Company will not have future charges for fair value write-up of acquired inventory, restructuring activities, deal and transaction costs, integration costs, asset or goodwill impairments, loss on extinguishment of debt or similar items and, therefore, may need to record additional charges (or credits) associated with such items, including the tax effects thereon. The exclusion of these items in the Company's non-GAAP measures should not be construed as an implication that these costs are unusual, infrequent or non-recurring.

Management considers these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures and evaluating these non-GAAP financial measures together with their most directly comparable financial measures calculated in accordance with GAAP. The calculations of Adjusted EBITDA, Adjusted Operating Income, and Non-GAAP EPS, and reconciliations between these financial measures and their most directly comparable GAAP equivalents, are presented below in the accompanying tables.

The reconciliation of GAAP measures to Adjusted Operating Income and Adjusted EBITDA for the years ended December 31, 2025 and 2024 are presented below:

**Item 7A. Quantitative and Qualitative Disclosure About Market Risks.**

Entegris' principal financial market risks are sensitive to interest rates and foreign currency exchange rates. The Company's interest-bearing cash and cash equivalents and variable rate debt are subject to interest rate fluctuations. The Company's cash and cash equivalents include cash on hand and highly-liquid debt securities with original maturities of three months or less. A 100-basis point change in interest rates would potentially increase or decrease annual net income by approximately $0.7 million and $2.5 million for the years ended December 31, 2025 and 2024, respectively.

The cash flows and results of operations of the Company's foreign-based operations are subject to fluctuations in foreign currency exchange rates. Approximately 17.5% and 16.7% of the Company's sales during 2025 and 2024, respectively, were collectively denominated in the South Korean won, New Taiwan dollar, Chinese renminbi, Canadian dollar, Malaysian ringgit, Singapore dollar, euro, Israeli shekel and the Japanese yen. Financial results therefore will be affected by changes in currency

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

exchange rates. If all foreign currencies were to see a 10% reduction versus the U.S. dollar during the years ended December 31, 2025 and 2024, revenue would be negatively impacted by approximately $55.9 million and $53.2 million, respectively.

The Company occasionally uses derivative financial instruments to manage the foreign currency exchange rate risks associated with its foreign-based operations. However, we are unlikely to be able to hedge these exposures completely. We do not enter into forward contracts or other derivative instruments for speculative or trading purposes. See Note 11 of the consolidated financials for additional information.

**Item 8. Financial Statements and Supplementary Data.**

The information called for by this item is set forth in the Consolidated Financial Statements covered by the Report of Independent Registered Public Accounting Firm at the end of this report.

**Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.**

Not applicable.

**Item 9A. Controls and Procedures.**

**Evaluation of Disclosure Controls and Procedures**

Based on management's evaluation (with the participation of our principal executive officer and principal financial officer), as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

**Changes in Internal Control Over Financial Reporting**

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Management Report on Internal Control Over Financial Reporting**

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of consolidated financial statements for external purposes in accordance with GAAP.

Management assessed our internal control over financial reporting as of December 31, 2025. Management based its assessment on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Management's assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.

Based on its assessment, management has concluded that our internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with GAAP. We reviewed the results of management's assessment with the Audit and Finance Committee of our Board of Directors.

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by KPMG LLP, our independent registered public accounting firm, as stated in their report which is included in F-2 of this Annual Report.

**Inherent Limitations on Effectiveness of Controls**

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well-designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and Board of Directors

Entegris, Inc.:

*Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting*

We have audited the accompanying consolidated balance sheets of Entegris, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

*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 the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's consolidated financial statements and an opinion 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 consolidated financial 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 consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial 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 consolidated financial 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 consolidated financial 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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

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 Matter*

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: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated 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.

*Evaluation of goodwill impairment for the MS reporting unit*

As discussed in Note 8 to the consolidated financial statements, the goodwill balance as of December 31, 2025 was $3.9 billion, $3.6 billion of which related to the Materials Solutions (MS) reporting unit. The Company performs goodwill impairment testing on an annual basis and whenever events or changes in circumstances indicate that the carrying value of a reporting unit exceeds its fair value. To estimate the fair value of the MS reporting unit, the Company utilized a combination of the income and market approaches. The income approach is a valuation technique under which we estimate future cash flows using the reporting unit's financial forecast from the perspective of an unrelated market participant. Using historical trending and internal forecasting techniques, we project revenue and apply our fixed and variable cost expense rate to the projected revenue to arrive at the future cash flows. A terminal value is then applied to the projected cash flow stream. Future estimated cash flows are discounted to their present value to calculate the estimated fair value. The discount rate used is the value-weighted average of our estimated cost of capital derived using both known and estimated customary market metrics. In determining the estimated fair value of a reporting unit, we are required to estimate a number of factors, including appropriate market comparable, projected future revenue growth and gross margins, the discount rate reflecting the risk inherent in future cash flows, the terminal growth rate, and projected future economic and market conditions. The market approach is a valuation technique under which we estimate the fair value of a reporting unit using publicly available market multiples for comparable companies.

We identified the evaluation of goodwill impairment for the MS reporting unit as a critical audit matter. Subjective auditor judgment, including specialized skills and knowledge, was required to evaluate management's assumptions used in the estimate of the fair value of the MS reporting unit. Specifically, the assessment encompassed the evaluation of the (1) projected revenue and discount rate under the income approach, and (2) market multiples under the market approach. These assumptions could have a significant effect on the Company's assessment and the determination of whether an impairment existed.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company's determination of the estimated fair value of the MS reporting unit, including controls related to management's process for assessing the appropriateness of certain assumptions including the projected revenue, discount rate and market multiples assumptions. We evaluated the Company's projected revenue by comparing it to market data for long-term industry and economic growth expectations from analyst reports in the semiconductor industry. We involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the reasonableness of the (1) discount rate by comparing it to a range of independently developed discount rates, and (2) market multiples by comparing to a market multiple range developed using publicly available market data for comparable entities.

We or our predecessor firms have served as the Company's auditor since 1966.

**ENTEGRIS, INC.**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**DECEMBER 31, 2025**

**1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Nature of Operations** Entegris, Inc. ("Entegris", the "Company", "we", or "our") is a leading supplier of advanced materials and process solutions for the semiconductor and other high-technology industries.

**Principles of Consolidation** The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation.

**Use of Estimates and Basis of Presentation** The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make judgments, estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, Entegris evaluates its estimates, including those related to receivables, inventories, property, plant and equipment, goodwill, intangible assets, accrued liabilities, income taxes and share-based compensation, among others. Actual results could differ from those estimates. Reclassifications of certain prior year amounts have been made to conform to the current year presentation.

**Cash and Cash Equivalents** Cash and cash equivalents include cash on hand and highly-liquid debt securities with original maturities of three months or less, which are valued at cost and approximate fair value.

**Allowance for Credit Losses** An allowance for uncollectible trade receivables is estimated based on a combination of write-off history, aging analysis and any specific, known troubled accounts. The Company maintains an allowance for credit losses that management believes is adequate to cover expected losses on trade receivables.

**Inventories** Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (FIFO) method. The Company records a charge to cost of sales for excess and obsolete inventory to reduce the carrying value of inventories to net realizable value.

**Leases** The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating and financing leases. Short-term operating lease liabilities are classified in "Other accrued liabilities" and long-term operating lease liabilities are classified in "Long-term lease liability - Operating lease" in the consolidated balance sheet. Short-term finance leases are classified in "Other accrued liabilities" and long-term finance lease liabilities are classified in "Long-term lease liability - Finance lease" in our consolidated balance sheet.

Lease assets and liabilities greater than 12 months are recognized at commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The ROU assets include prepaid lease payments and exclude lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Leases with an original term of 12 months or less are not recorded in the accompanying consolidated balance sheet.

Lease and non-lease components are generally accounted for separately for real estate leases. For non-real estate leases, we account for the lease and non-lease components as a single lease component.

**Property, Plant and Equipment** Property, plant and equipment are carried at cost and are depreciated using the straight-line method over their estimated useful lives. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in the period incurred. Maintenance and repairs are expensed as incurred, while significant additions and improvements are capitalized. Long-lived assets, including property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable based on estimated future undiscounted cash flows. The amount of impairment, if any, is measured as the difference between the net book value and the estimated fair value of the asset(s).

In January 2026, we completed an assessment of the useful lives of our property, plant and equipment and adjusted the estimated useful lives of certain property, plant and equipment to more closely reflect the expected economic lives of these assets. These adjustments followed an analysis of our actual usage of assets, including the technological and physical obsolescence of these assets, our ability to continue to use equipment, historical usage trends, and anticipated capital plans and technology roadmaps, as well as industry trends and practices. Based on this analysis, we determined that the increase in useful lives was warranted and consistent with the Company's historical and anticipated use of these assets. The updated estimated useful lives of certain assets for financial reporting purposes are as follows: buildings and improvements, 5 to 35 years increased to 5 to 40 years; manufacturing equipment, 5 to 10 years increased 5 to 14 years; canister and cylinder, 3 to 12 years increased to 3 to 19 years; molds, 3 to 5 years increased to 3 to 9 years and lab equipment, 3 to 8 years increased to 3 to 9 years.

**Fair Value of Financial Instruments** The carrying value of cash equivalents, accounts receivable, accounts payable, accrued payroll and related benefits, and other accrued liabilities approximates fair value due to the short maturity of those instruments. Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level hierarchy for disclosure is based on the extent and level of judgment used to estimate fair value. Level 1 inputs consist of valuations based on quoted market prices in active markets for identical assets or liabilities. Level 2 inputs consist of valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in an inactive market, or other observable inputs. Level 3 inputs consist of valuations based on unobservable inputs that are supported by little or no market activity.

**Goodwill and Intangible Assets** Goodwill represents the excess of acquisition costs over the fair value of the net assets of businesses acquired. Goodwill is not subject to amortization, but is tested for impairment annually at August 31, the Company's annual testing date, and whenever events or changes in circumstances indicate that impairment may have occurred.

In performing the Company's annual goodwill impairment test, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the carrying amount of the Company's reporting unit exceeds its fair value including goodwill. In performing the qualitative assessment, the Company considers certain events and circumstances specific to the reporting unit and to the entity as a whole, such as macroeconomic conditions, industry and market considerations, overall financial performance and cost factors when evaluating whether it is more likely than not that the carrying value of the reporting unit exceeds its fair value. The Company is also permitted to bypass the qualitative assessment and proceed directly to the quantitative assessment. If the Company chooses to undertake the qualitative assessment and concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the Company would then proceed to the quantitative impairment assessment. In the quantitative assessment, the Company compares the fair value of the reporting unit to its carrying amount, which includes goodwill. If the fair value exceeds the carrying value, no impairment loss exists. If the fair value is less than the carrying amount, a goodwill impairment loss is measured and recorded.

The quantitative impairment test requires us to estimate the fair value of a reporting unit, which is based on a combination of the income and market approaches. The income approach is a valuation technique under which we estimate future cash flows using the reporting unit's financial forecast from the perspective of an unrelated market participant. Using historical trending and internal forecasting techniques, we project revenue and apply our fixed and variable cost expense rate to the projected revenue to arrive at the future cash flows. A terminal value is then applied to the projected cash flow stream. Future estimated cash flows are discounted to their present value to calculate the estimated fair value. The discount rate used is the value-weighted average of our estimated cost of capital derived using both known and estimated customary market metrics. In determining the estimated fair value of a reporting unit, we are required to estimate a number of factors, including appropriate market comparable, projected future revenue growth and gross margins, the discount rate reflecting the risk inherent in future cash flows, the terminal growth rate, and projected future economic and market conditions. The market approach is a valuation technique under which we estimate the fair value of a reporting unit using publicly available market multiples for comparable companies.

Amortizable intangible assets include, among other items, patented, unpatented and other developed technology and customer-based intangibles, and are amortized using the straight-line method over their respective estimated useful lives. The Company reviews intangible assets and other long-lived assets for impairment if changes in circumstances or the occurrence of events suggest the remaining value may not be recoverable.

**Derivative Financial Instruments** The Company is exposed to various market risks, including risks associated with interest rates and foreign currency exchange rates. We enter into certain derivative transactions to mitigate the volatility associated with these exposures. We have policies in place that define acceptable instrument types we may enter into and we have established controls to limit our market risk exposure. We do not use derivative financial instruments for trading or speculative purposes. In addition, all derivatives, whether designated in hedging relationships or not, are recorded on the consolidated balance sheets at fair value on a gross basis.

<u>Interest Rate Swap</u>

The fair value of the interest rate swap is estimated using standard valuation models using market-based observable inputs over the contractual term, including one-month Secured Overnight Financing Rate ("SOFR") based yield curves, among others. We consider the risk of nonperformance, including counterparty credit risk, in the calculation of the fair value. We have designated this swap agreement as a cash flow hedge. As a cash flow hedge, unrealized gains are recognized as assets and unrealized losses are recognized as liabilities. Unrealized gains and losses are designated as effective or ineffective based on a comparison of the changes in fair value of the interest rate swap and changes in fair value of the underlying exposures being hedged. The effective portion is recorded as a component of accumulated other comprehensive loss, while the ineffective portion is recorded as a component of Interest expense. Changes in the method by which we pay interest from one-month SOFR to another rate of interest could create ineffectiveness in the swap, and result in amounts being reclassified from other comprehensive income

(loss) into net income. Hedge effectiveness is tested quarterly to determine if hedge treatment is appropriate. Realized gains and losses are recorded on the same financial statement line as the hedged item, which is Interest expense.

<u>Foreign Currency Contracts Not Designated as Hedges</u>

On a periodic basis, we enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures. These foreign exchange contracts do not qualify for hedge accounting; therefore, the gains and losses resulting from the impact of currency exchange rate movements on our forward foreign exchange contracts are recognized as Other expense (income), net in the accompanying consolidated statements of operations in the period in which the exchange rates change.

**Foreign Currency Translation** Assets and liabilities of certain foreign subsidiaries are translated from foreign currencies into U.S. dollars at period-end exchange rates, and the resulting gains and losses arising from translation of net assets located outside the U.S. are recorded as a cumulative translation adjustment, a component of accumulated other comprehensive loss in the consolidated balance sheets. Income statement amounts are translated at the average exchange rates for the year. Translation adjustments are not adjusted for income taxes, as substantially all translation adjustments relate to permanent investments in non-U.S. subsidiaries. Gains and losses resulting from foreign currency transactions are included in Other expense (income), net, in the Company's consolidated statements of operations.

**Revenue Recognition** Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer.

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.

Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales.

The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less.

When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from advance payments received on sales of the Company's products. The Company makes the required disclosures with respect to deferred revenue in Note 2 to the consolidated financial statements.

The Company does not disclose information about remaining performance obligations that have original expected durations of one year or less.

The following is a description of principal activities from which the Company generates its revenues. The Company has two reportable segments. For more detailed information about reportable segments, see Note 20 to the consolidated financial statements. For each of the two reportable segments, the recognition of revenue regarding the nature of goods and services provided by the segments are similar and described below. The Company recognizes revenue for product sales at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment or delivery, depending on the terms of the underlying contracts. For product sales contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognizes the related revenue as control of each individual product is transferred to the customer in satisfaction of the corresponding performance obligations. All material revenue is being recognized at a point in time.

The Company generally recognizes revenue for sales of services when the Company has satisfied the performance obligation. The payment terms and revenue recognized are based on time and materials.

The Company also enters into arrangements to license its intellectual property. These arrangements typically permit the customer to use a specialized manufacturing process and in return the Company receives a royalty fee. The Company recognizes revenue for a sales-based or usage-based royalty promised in exchange for a license of intellectual property when the subsequent sale or usage occurs.

The Company offers certain customers cash discounts and volume rebates as sales incentives. The discounts and volume rebates are recorded as a reduction in sales at the time revenue is recognized in an amount estimated based on historical experience and contractual obligations. The Company periodically reviews the assumptions underlying its estimates of discounts and volume rebates and adjusts its revenues accordingly.

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

In addition, the Company offers free product rebates to certain customers. The Company utilizes an adjusted market approach to estimate the stand-alone selling price of the loyalty program and allocates a portion of the consideration received to the free product offering. The free product offering is redeemable upon future purchases of the Company's products. The amount associated with free product rebates is recorded as deferred revenue on the balance sheet and is recognized as revenue when the free product is redeemed or when the likelihood of redemption is remote. The Company has deemed that the amount is immaterial for disclosure.

The Company provides for the estimated costs of fulfilling its obligations under product warranties at the time the related revenue is recognized. The Company estimates the costs based on historical failure rates, projected repair costs, and knowledge of specific product failures (if any). The specific warranty terms and conditions vary depending upon the product sold and the country in which we do business, but generally include parts and labor over a period generally ranging from 90 days to one year. The Company regularly reevaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjusts the amounts as necessary.

The Company's contracts are generally short-term in nature. Most contracts do not exceed twelve months. Payment terms vary by the type and location of the Company's customers and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. Those customers that prepay are represented by the contract liabilities until the performance obligations are satisfied.

**Engineering, Research and Development Expenses** Engineering, research and development expenses are expensed as incurred.

**Share-Based Compensation** The Company measures the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant. Share-based compensation expense is recognized using the straight-line attribution method to recognize share-based compensation over the service period of the award, with adjustments recorded for forfeitures as they occur. Awards issued to employees who are retirement eligible or nearing retirement eligibility are expensed on an accelerated basis.

**Government Grants** The Company entered into certain incentive arrangements with the state of Colorado and U.S. Department of Commerce. We account for funds we receive from government grants by either reducing the costs of the assets (if the grant relates to capital expenditures) or expenses which could be Cost of goods sold, Selling, general and administrative, and Research and development expenses in the consolidated statements of income. We recognize the incentives when there is reasonable assurance that we will comply with all conditions specified in the incentive arrangement and the incentive will be received.

**Income Taxes** The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date.

The Company recognizes deferred tax assets to the extent that it believes these assets are more likely than not to be realized. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that the Company would not be able to realize all or part of its deferred tax assets. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company's policy for recording interest and penalties associated with audits and unrecognized tax benefits is to record such items as a component of income before taxes. Penalties and interest to be paid or received are recorded in other expense (income), net, in the statement of operations.

**Comprehensive Income** Comprehensive income represents the change in equity resulting from items other than shareholder investments and distributions. The Company's foreign currency translation adjustments, unrealized gains and losses on available-for-sale investments, interest rate swap - cash flow hedge and minimum pension adjustments are included in accumulated other comprehensive loss. Comprehensive income and the components of accumulated other comprehensive loss are presented in the accompanying consolidated statements of comprehensive income and consolidated statements of equity.

**Recent Accounting Pronouncements Adopted**

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

During the year ended December 31, 2025, the Company adopted Accounting Standards Update (ASU) 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. The Company applied the guidance prospectively by providing the revised disclosures for the year ended December 31, 2025 and by providing the pre-ASU disclosures for the prior periods. These changes did not impact the Company's consolidated financial results but provide additional information for users of the financial statements. See Note 16 to the consolidated financial statements for further details.

**Recent Accounting Pronouncements Yet to be Adopted**

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires public companies to disclose, in interim and annual reporting periods, additional information about certain expenses in the notes to financial statements. The amendments in this ASU are effective for our annual reporting periods beginning in fiscal year 2027 and interim reporting periods beginning in the first quarter of fiscal year 2028, with early adoption permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements and related disclosures.

The Company currently has no other material recent accounting pronouncements yet to be adopted.

**3. GOODWILL AND LONG-LIVED ASSET IMPAIRMENT**

During 2023, the Company was exploring market interest in sales of two of our businesses, Electronic Chemicals ("EC") and a small, industrial specialty chemicals business, both within our Materials Solutions ("MS") segment. As a result, the Company had triggering events and evaluated goodwill and long-lived assets for impairment.

<u>Goodwill</u>

In 2023, the Company compared the reporting units' fair value to the carrying amounts, including goodwill. As the reporting units' carrying amount, including goodwill exceeded fair value, the Company recorded goodwill impairment charges of $115.2 million in 2023. The impairment is classified as goodwill impairment in the Company's consolidated statement of operations. The goodwill impairment is not deductible for tax purposes. The fair value of the reporting unit was determined using a market and income-based approach. We consider this a Level 3 measurement in the fair value hierarchy. There was no goodwill impairment charge recorded during 2024 or 2025.

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

<u>Long-lived assets, including finite-lived intangible assets</u>

The Company compared the estimated undiscounted future cash flows generated by the asset groups to the carrying amount of the asset groups for the reporting units and determined that the undiscounted cash flows were expected to exceed the carrying value on a held and used basis for the EC business but did not for the small, industrial specialty chemical business. As a result, the Company recorded an impairment of $30.5 million in 2023 and $13.0 million in 2024 related to the industrial specialty chemical business. The impairment is classified as selling, general and administrative expenses in the Company's consolidated statements of operations. The fair value of the reporting unit was determined using a market-based approach. We consider this a Level 3 measurement in the fair value hierarchy. The small, industrial specialty chemical business was sold during the fourth fiscal quarter of 2025; see Note 4 for further discussion.

During 2025, the Company recorded an impairment charges of $11.7 million related to long-lived assets as a result of restructuring initiatives that took place during the year. See Note 15 for further discussion.

**4. DIVESTITURE**

<u>Divestiture - Other</u>

During the fourth quarter of 2025, the Company completed the sale of its small, industrial specialty chemicals business that reports within the MS segment and was presented as Held for Sale as of December 31, 2024 and 2023. We incurred $6.7 million of costs associated with the disposition of the business. As a result of the disposition, we recorded a loss of $10.9 million, which included direct costs to sell the business. We presented the net loss in Selling, general and administrative expenses in the consolidated statements of operations for the year ended December 31, 2025.

The disposition of the business did not meet the criteria to be classified as a discontinued operation in the Company's financial statements since the disposition did not represent a strategic shift that had, or will have, a major effect on the Company's operations and financial results.

<sup>(1)</sup> Intangible assets acquired in a business combination that are in-process and used in research and development activities are considered indefinite-lived until the completion or abandonment of the research and development efforts. Once the research and development efforts are completed, we determine the useful life and begin amortizing the assets. All in-process research and development assets that were open as of December 31, 2024 were completed and reclassified to developed technology and began amortizing in 2025.

The table below sets forth the amortization expense for finite-lived intangible assets for the years ended December 31, 2025, 2024, and 2023:

<sup>(2)</sup> Our senior secured revolving credit facility due 2027 (the "Revolving Facility") bears interest at a rate per annum equal to, at the Company's option, either (i) SOFR, plus an applicable margin of 1.75%, or (ii) a base rate plus an appliable margin of 0.75%. The Revolving Facility has commitments of $575.0 million. There were no borrowing outstanding under the Revolving Facility as of December 31, 2025 and December 31, 2024.

During the year ended December 31, 2025, the Company has repaid $300.0 million of the outstanding borrowings under the senior secured term loan. In connection with these repayments, the Company incurred a pre-tax loss on extinguishment of debt of $3.2 million for the year ended December 31, 2025, which is included in Other expense, net on the consolidated statements of operations.

**10. FAIR VALUE OF FINANCIAL INSTRUMENTS**

The Company is required to record certain assets and liabilities at fair value. The valuation methods used for determining the fair value of these financial instruments by hierarchy are as follows:

*Level 1* Cash and cash equivalents consist of various bank accounts used to support our operations and investments in institutional money-market funds that are traded in active markets.

*Level 2* Derivative financial instruments include an interest rate swap contract and foreign exchange contracts. The fair value of our derivative instruments is estimated using standard valuation models and market-based observable inputs over the contractual term, including the prevailing SOFR-based yield curves for the interest rate swap, and forward rates and/or the Overnight Index Swap curve for forward foreign exchange contracts, among others. The fair value of our debt is estimated based on independent broker/dealer bids or by comparison to other debt securities having similar durations, yields and credit ratings.

*Level 3* No Level 3 financial instruments

The following table presents financial instruments that we measure at fair value on a recurring basis. See Note 9 to our consolidated financial statements for a discussion of our debt. In instances where the inputs used to measure the fair value of an asset fall into more than one level of the hierarchy, we have classified it based on the lowest level input that is significant to the determination of the fair value.

**11. DERIVATIVE INSTRUMENTS**

The Company is exposed to various market risks, including risks associated with interest rates and foreign currency exchange rates. One objective of the Company's risk management program is to mitigate these risks using derivative instruments.

<u>Cash Flow Hedges - Interest Rate Swap Contract</u>

In July 2022, the Company entered into a floating-to-fixed swap agreement on its variable rate debt under the Term Loan Facility. The interest rate swap was designated specifically to the Term Loan Facility, was highly effective and qualified as a cash flow hedge. The notional amount was scheduled to decrease quarterly and expired on December 30, 2025. As cash flow hedges, unrealized gains are recognized as assets and unrealized losses are recognized as liabilities. Unrealized gains and losses

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

are designated as effective or ineffective based on a comparison of the changes in fair value of the interest rate swaps and changes in fair value of the underlying exposures being hedged. The effective portion is recorded as a component of Accumulated other comprehensive loss and will be reflected in earnings during the period the hedged transaction effects earnings, while the ineffective portion is recorded as a component of Interest expense.

<u>Foreign Currency Contracts Not Designated as Hedges</u>

The Company may enter into foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures. These foreign exchange contracts do not qualify for hedge accounting. The Company recognizes the change in fair value of its foreign currency forward contracts in the consolidated statement of operations.

**15. RESTRUCTURING COSTS**

During 2025, the Company initiated certain business restructuring activities aimed at improving operational efficiency and aligning resources with strategic priorities. These activities resulted in restructuring charges of $29.7 million for the year ended December 31, 2025, primarily related to (i) an internal reorganization, combining two complementary divisions into one and realigning its customer facing organization, which occurred in the fourth quarter of 2024, and (ii) commencing in the second quarter of 2025, workforce reductions, contract termination costs and the abandonment of certain capital equipment no longer necessary for the Company's long-term objectives. These restructuring activities are deemed to be discrete initiatives that are different from the Company's ongoing productivity improvements.

The charges related to these restructuring activities were recognized in the consolidated statements of operations for the year ended December 31, 2025 as follows:

The Company has made employment and spending commitments to Singapore. In return for those commitments, the Company was granted a partial tax holiday for eight years starting in 2013. During 2017, this agreement was extended to 2027 in exchange for revised employment and spending commitments. The income tax benefits attributable to the tax status are $26.1 million ($0.17 per diluted share), $27.7 million ($0.18 per diluted share) and $19.7 million ($0.13 per diluted share) for the years ending December 31, 2025, 2024 and 2023, respectively. The 2025, 2024 and 2023 effective tax rates include additional benefits of $16.1 million, $17.1 million and $12.1 million because the corporate tax rate in Singapore is lower than the U.S. rate.

At December 31, 2025, there were approximately $393.2 million of accumulated undistributed earnings of subsidiaries outside of the United States, all of which are considered to be indefinitely reinvested. Management estimates that approximately $26.1 million of withholding taxes would be incurred if these undistributed earnings were distributed.

The significant components of the Company's deferred tax assets and deferred tax liabilities at December 31, 2025 and 2024 are as follows:

Deferred tax assets are generally required to be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

As of December 31, 2025 and 2024, the Company had net U.S. deferred tax assets of $117.5 million and deferred tax assets of $20.1 million, respectively, which are composed of temporary differences and various tax credit carryforwards. The Company had state operating loss and credit carryforwards of approximately $30.5 million, which begin to expire in 2026. Management

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

believes that it is more likely than not that the benefit from certain state net operating loss carryforwards, state credit carryforwards, capital loss carryforwards and certain federal foreign tax credit carryforwards will not be realized. In recognition of this risk, management has provided valuation allowances of $40.8 million and $36.5 million as of December 31, 2025 and 2024, respectively, on the related deferred tax assets. If the assumptions change and management determines the assets will be realized, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets at December 31, 2025 will be recognized as a reduction of income tax expense.

As of December 31, 2025 and 2024, the Company had net non-U.S. deferred tax assets of $50.7 million and $44.2 million, respectively, for which management determined based upon the available evidence a valuation allowance of $38.3 million and $35.3 million as of December 31, 2025 and 2024, respectively, was required against the non-U.S. gross deferred tax assets. For other non-U.S. jurisdictions, management relies upon projections of future taxable income to utilize deferred tax assets.

At December 31, 2025, the Company had foreign operating loss carryforwards of $69.7 million, which begin to expire in 2026.

Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax positions will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that fail to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The provisions also provide guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.

Reconciliations of the beginning and ending balances of the total amounts of gross unrecognized tax benefits for the years ended December 31, 2025 and 2024 are as follows:

---

| | | |
|:---|:---|:---|
| *<u>(In millions)</u>* | **2025** | **2024** |
| Gross unrecognized tax benefits at beginning of year | $44.3 | $67.7 |
| Increase in tax positions from prior years | 0.1 | 0.3 |
| Decrease in tax positions from prior years | (5.6) | (4.8) |
| Increases in tax positions for current year | 7.2 | 5.5 |
| Settlement of tax positions for current year | (0.7) | (21.6) |
| Lapse in statute of limitations | (11.6) | (2.8) |
| Gross unrecognized tax benefits at end of year | $33.7 | $44.3 |

---

The total amount of net unrecognized tax benefits that, if recognized, would affect the effective tax rate was $28.4 million at December 31, 2025.

Penalties and interest paid or received are recorded in other expense, net in the consolidated statements of operations. As of December 31, 2025 and 2024, the Company had accrued interest and penalties related to unrecognized tax benefits of $5.1 million and $6.0 million, respectively. Expenses of $1.0 million, $3.0 million and $2.5 million were recognized as interest and penalties in the consolidated statements of operations for the years ended December 31, 2025, 2024 and 2023, respectively.

The Company files income tax returns in the U.S. and in various state, local and foreign jurisdictions. The statutes of limitations related to both the consolidated federal income tax return and state returns are closed for all years up to and including 2021 and 2021, respectively. With respect to foreign jurisdictions, the statute of limitations varies from country to country, with the earliest open year for the Company's major foreign subsidiaries being 2019.

The significant components of the Company's income taxes paid (net of refunds) at December 31, 2025 are as follows:

**<u>Pillar 2</u>**

The Organization Economic Co-operation and Development ("OECD") introduced Base Erosion and Profit Shifting ("BEPS") Pillar 2 rules that impose a global minimum tax rate of 15%. Numerous countries have already enacted, or are expected to enact, legislation to implement the 15% minimum tax rate. There was no material impact in 2025 and we will continue to evaluate the future potential impact on our consolidated financial statements and related disclosures.

**<u>One Big Beautiful Bill Act (the "Act")</u>**

The Act was enacted on July 4, 2025. In accordance with ASC 740-10, the Company accounted for the effects of the new tax legislation in the quarter ended September 27, 2025, which is the quarter of enactment. The key provisions of the Act impacting the Company's financial statements include the modification of interest expense limitations under IRC Section 163(j) and revisions to foreign-derived intangible income (FDII) and global intangible low-taxed income (GILTI). Certain provisions of the Act are effective for tax years beginning after December 31, 2025, and therefore did not affect the current year financial results. The Company will continue to evaluate the impact of the Act on its future tax positions.

**17. EQUITY**

**Dividends**

Holders of the Company's common stock are entitled to receive dividends when and if they are declared by the Company's board of directors. The Company's board of directors declared quarterly cash dividends of $0.10 per share during 2025, which totaled $61.1 million. The Company's board of directors declared quarterly cash dividends of $0.10 per share during 2024, which totaled $60.7 million. The Company's board of directors declared quarterly cash dividends of $0.10 per share during 2023, which totaled $60.3 million.

On January 14, 2026, the Company's board of directors declared a quarterly cash dividend of $0.10 per share to be paid on February 18, 2026 to shareholders of record as of January 28, 2026.

Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of the Company's board of directors.

**2020 Stock Plan**

In 2020, the Company's board of directors and stockholders approved the Entegris, Inc. 2020 Stock Plan (the "2020 Stock Plan"). The 2020 Stock Plan replaced the Entegris, Inc. 2010 Stock Plan for future stock awards and stock option grants. The 2020 Stock Plan has a term of ten years and provides for the issuance of stock options and other share-based awards to selected employees, directors, and other individuals or entities that provide services to the Company or its affiliates. Under the 2020 Stock Plan, the board of directors or a committee selected by the board of directors will determine for each award, the term, price, number of shares, rate at which each award is exercisable and whether restrictions are imposed on the shares subject to the awards. The exercise price for option awards generally may not be less than the fair market value per share of the underlying common stock on the date granted. The 2020 Stock Plan provides that after December 31, 2019, any shares subject to stock awards that were awarded from the Company's expired plans and that are forfeited, expired or otherwise terminated without issuance of shares will again be available for issuance under the 2020 Stock Plan.

For all plans, exclusive of the employee stock purchase plan, the Company had shares available for future grants of 8.7 million, 9.7 million, and 10.2 million shares at December 31, 2025, 2024 and 2023, respectively.

---

The weighted average remaining contractual term for options outstanding and options exercisable for all plans at December 31, 2025 was 4.0 years and 2.9 years, respectively.

Under the stock plans, the total pre-tax intrinsic value of stock options exercised during the years ended December 31, 2025 and 2024 was $7.1 million and $23.2 million, respectively. The aggregate intrinsic value, which represents the total pre-tax intrinsic value based on the Company's closing stock price of $84.25 at December 31, 2025, which theoretically could have been received by the option holders had all option holders exercised their options as of that date, was $8.9 million and $8.0 million for options outstanding and options exercisable, respectively.

Share-based payment awards in the form of stock option awards for 0.3 million, 0.2 million and 0.2 million shares were granted to employees during the years ended December 31, 2025, 2024 and 2023, respectively. Compensation expense is based on the grant date fair value. The awards vest annually over a period of four years and have a contractual term of 7 years. The Company estimates the fair value of stock options using the Black-Scholes valuation model. Key inputs and assumptions used to estimate the fair value of stock options include the grant price of the award, the expected option term, volatility of the Company's stock, the risk-free rate and the Company's dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of reasonableness of the original estimates of fair value made by the Company.

The fair value of each stock option grant was estimated at the date of grant using a Black-Scholes option pricing model. The following table presents the weighted-average assumptions used in the valuation and the resulting weighted-average fair value per option granted for the years ended December 31, 2025, 2024 and 2023:

---

| | | | |
|:---|:---|:---|:---|
| *Employee stock options:* | **2025** | **2024** | **2023** |
| Volatility | 47.0% | 47.6% | 46.5% |
| Risk-free interest rate | 3.9% | 4.4% | 3.7% |
| Dividend yield | 0.5% | 0.3% | 0.5% |
| Expected life (years) | 4.7 | 4.6 | 4.7 |
| Weighted average fair value per option | $35.70 | $61.94 | $34.40 |

---

A historical daily measurement of volatility is determined based on the expected life of the option granted. The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the

------

<u>[**Table of Contents**](#ia4639f5d7d03482094930f75a9ceca45_7)</u>

option granted. Expected life is determined by reference to the Company's historical experience. The Company determines the dividend yield by dividing the expected annual dividend on the Company's stock by the option exercise price.

**Employee Stock Purchase Plan**

The Company's Employee Stock Purchase Plan ("ESPP") allows employees to elect, at six-month intervals, to contribute up to 10% of their compensation, subject to certain limitations, to purchase shares of the Company's common stock at a discount of 15% from the fair market value on the first day or last day of each six-month period. The Company treats the ESPP as a compensatory plan. At December 31, 2025, 2.3 million shares remained available for issuance under the ESPP. Employees purchased 0.3 million, 0.2 million and 0.2 million shares, at a weighted-average price of $69.24, $89.59, and $68.87 during the years ended December 31, 2025, 2024 and 2023, respectively.

**Restricted Stock Units**

Restricted stock units are awards of common stock made under the Stock Plans that are subject to a risk of forfeiture if the awardee terminates employment with the Company prior to the lapse of the restrictions. The value of such restricted stock units is determined using the market price on the grant date. Compensation expense for restricted stock units is generally recognized using the straight-line single-option method. A summary of the Company's restricted stock unit activity for the years ended December 31, 2025, 2024 and 2023 is presented in the following table:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|

| Unvested, end of year | 1.3 | 98.40 | 1.1 | 111.81 | 1.0 | 89.08 |

---

During the years ended December 31, 2025, 2024 and 2023, the Company awarded performance-based restricted stock units for up to 0.3 million, 0.1 million and 0.2 million shares of common stock, respectively, to be issued upon the achievement of performance conditions under the Company's stock plans to certain officers. Compensation expense is based on the grant date fair value. The awards vest on the third anniversary of the award date if the performance conditions have been satisfied. The Company estimates the fair value of the performance shares using a Monte Carlo simulation process.

As of December 31, 2025, the total compensation cost related to unvested stock options, performance-based restricted stock units and restricted stock unit awards not yet recognized was $8.2 million, $7.2 million and $70.4 million, respectively, and is expected to be recognized over the next 2.7 years on a weighted-average basis.

**Modification**

During the year ended December 31, 2023, the Company modified restricted share units, options, and performance-based restricted share units granted prior to the 2022 fiscal year for certain employees to accelerate the unvested awards upon their respective retirements from the Company. The Company accounted for this as a modification of awards and recognized incremental compensation cost of $0.7 million for the year ended December 31, 2023. The incremental compensation cost was measured as the excess of the fair value of the modified award over the fair value of the original award immediately before its terms were modified and was recognized on the date of the modification for the vested awards.

There were no material modifications to employee awards during the years ended December 31, 2025 and 2024.

**Valuation and Expense Information**

The Company recognizes compensation expense for all share-based payment awards made to employees and directors based on their estimated fair values on the date of grant. Compensation expense is recognized using the straight-line attribution method to recognize share-based compensation over the service period of the award, with adjustments recorded for forfeitures as they occur. Awards issued to employees who are retirement eligible or nearing retirement eligibility are expensed on an accelerated basis. The following table summarizes the allocation of share-based compensation expense related to employee stock options, restricted stock awards, performance-based restricted stock awards and grants under the employee stock purchase plan for the years ended December 31, 2025, 2024 and 2023:

**18. BENEFIT PLANS**

**401(k) Plan** 

The Company maintains 401(k) defined contribution plans covering employees in the U.S. The related expense totaled $24.0 million, $24.6 million and $25.4 million in the fiscal years ended December 31, 2025, 2024 and 2023, respectively. During the year ended December 31, 2025, the Company matched employees' contributions to a maximum of 6% of the employee's eligible wages. The Company's Singapore, Japan and South Korea subsidiaries also make contributions to retirement plans that function as defined contribution retirement plans, however these costs are immaterial.

**Defined Benefit Plans** 

The employees of the Company's subsidiaries in Japan, Taiwan, France and Germany are covered in defined benefit pension plans. On January 1, 2025, the Company converted 50% of its CMC Japan defined pension plans to defined contribution plans and amended the remaining 50% to be frozen. The resulting conversion and amendment to the plans reduced the benefit obligation by $2.8 million in the year ended December 31, 2025. The Company uses a December 31 measurement date for its pension plans. A summary of these combined plans are:

---

| Plan assets less benefit obligation - net amount recognized | (7.6) | (10.1) |
| Accumulated benefit obligation | 8.2 | 9.0 |

---

*Cash Flows*

Benefits for the combined plans were $0.2 million, $0.6 million and $1.0 million in fiscal years 2025, 2024 and 2023, respectively, consisting primarily of service costs. Net service costs are included in Cost of sales and Operating expenses, and all other costs are recorded in Other expense, net in our Consolidated Statements of Operations. The Company expects to make the following benefit payments:

---

**19. EARNINGS PER COMMON SHARE**

Basic earnings per common share ("EPS") is calculated based on the weighted average number of shares of common stock outstanding during the applicable period. Diluted EPS is calculated based on the weighted average number of shares of common stock outstanding plus potentially dilutive shares of common stock outstanding during the applicable period. The following table presents a reconciliation of the share amounts used in the computation of basic and diluted EPS:

**20. SEGMENT INFORMATION**

Our business is organized and operated in two operating segments as discussed below. These segments share common business systems and processes, technology centers and technology roadmaps. With our complementary capabilities, we believe we are uniquely positioned to create new, co-optimized and increasingly integrated solutions for our customers, which should translate into improved device performance, lower cost of ownership and faster time to market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Materials Solutions segment, or MS, provides materials-based solutions, such as chemical vapor and atomic layer deposition materials, chemical mechanical planarization ("CMP") slurries and pads, ion implantation specialty gases, formulated etch and clean materials, and other specialty materials that enable our customers to achieve better device performance and faster time to yield, while providing for lower total cost of ownership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Advanced Purity Solutions segment, or APS, offers filtration, purification and contamination-control solutions that improve customers' yield, device reliability and cost by ensuring the purity of critical liquid chemistries and gases and the cleanliness of wafers and other substrates used throughout semiconductor manufacturing processes, the semiconductor ecosystem and other high-technology industries.

The Company's method for measuring profitability on a reportable segment basis is segment profit. Segment profit is defined as net sales less direct and indirect segment operating expenses, including certain general and administrative costs for the Company's human resources, finance and information technology functions. The Company accounts for inter-segment sales and transfers as if the sales or transfers were to third parties. Inter-segment sales are presented as an elimination below. The remaining unallocated expenses consist mainly of the Company's corporate functions as well as interest expense, interest income, amortization of intangible assets and income tax expense.

The Company's chief operating decision maker (CODM) is the President and Chief Executive Officer. For each of the reportable segments, the CODM uses segment profit (based on each segment's target model) for determining the allocation of resources (including employees, financial, or capital resources) to the segments to achieve the Company's strategic plan and to assess the performance of each segment by monitoring actual results against performance targets established in the Company's annual budget and forecasting process. Total assets by segment are not presented as that information is not used to allocate resources or assess performance at the segment level and is not regularly reviewed by the Company's CODM.

Summarized financial information for the Company's reportable segments is shown in the following tables for the years ended December 31, 2025, 2024 and 2023:

**22. COMMITMENTS AND CONTINGENT LIABILITIES**

We are, from time-to-time, involved in various claims, proceedings and lawsuits relating to our business, employees, intellectual property and other matters. The outcomes of these legal actions are not within our complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, that could require significant expenditures or result in lost revenues. We record a liability for these legal actions when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. There is judgment required in the determination of the likelihood of outcome, and if necessary determination of the estimate or range of potential outcomes. Based on the current information, the Company does not believe any known matters have a reasonable possibility of a material amount for litigation or other contingencies related to legal proceedings.

**23. SUBSEQUENT EVENTS**

The Company has evaluated subsequent events to the date of the issuance of the consolidated financial statements. The Company has determined that there are no events occurring in this period that require disclosure or adjustment, except as disclosed above.
