OUR COMPANY

Entegris, Inc. (“Entegris”, “the Company”, “us”, “we”, or “our”) is a leading supplier of advanced materials and process solutions for the semiconductor and other high-technology industries. Our mission is to help our customers improve their productivity, performance and technology by providing solutions for the most advanced manufacturing environments. We leverage our unique breadth of capabilities to create mission-critical microcontamination control products, specialty chemicals and advanced materials handling solutions that maximize manufacturing yields, reduce manufacturing costs and enable higher device performance for our customers.

Semiconductors, or integrated circuits, are key components in the electronic devices that have changed the way we live, communicate and work. Products and applications like smartphones, 5G wireless technology, cloud computing, the Internet of Things, machine learning and artificial intelligence, autonomous vehicles and virtual reality will increasingly require faster, more powerful and more energy efficient semiconductors and we believe will ultimately drive global chip demand.

To meet the requirements for improved chip performance and density, semiconductor manufacturing processes have rapidly become increasingly complex by moving to smaller geometries, adopting new device architectures and utilizing new and innovative materials. These complex processes require new materials of ever-increasing purity, quality and stability to improve and maximize yields. We expect to benefit from these two intersecting themes of the growing importance of process materials and materials purity, and the impact they have on semiconductor performance, cost and reliability. We believe these trends are leading to increasing materials content per wafer and filtration opportunity per wafer, which are growth opportunities for us.

Our customized materials solutions enable the highest levels of performance essential to the manufacture of semiconductors. As our customers introduce more complex architectures and search for new materials with better electrical and structural properties to improve the performance of their devices, they rely on Entegris as a trusted partner to address these challenges. We understand these challenges and have solutions to address them, such as our advanced deposition materials, implant gases, formulated cleaning chemistries and selective etch chemistries. Our customers also require greater end-to-end materials purity and integrity in their manufacturing processes that, when combined with smaller dimensions and more complex architectures, can be challenging to achieve. To enable the use of new metals and the further miniaturization of chips, and to maximize yield and increase long-term device reliability, we provide products such as our advanced liquid and gas filtration and purification products that help to selectively remove new classes of contaminants throughout the semiconductor supply chain. In addition, to ensure purity levels are maintained across the entire supply chain, from bulk manufacturing, to transportation to and delivery through a fab, to application onto the wafer, we provide high-purity packaging and materials handling products.

Our business is organized and operated in three operating segments, which align with the key elements of the advanced semiconductor manufacturing ecosystem. The Specialty Chemicals and Engineered Materials, or SCEM, segment provides high-performance and high-purity process chemistries, gases and materials, and safe and efficient delivery systems to support semiconductor and other advanced manufacturing processes. The Microcontamination Control, or MC, segment offers solutions to filter and purify critical liquid chemistries and gases used in semiconductor manufacturing processes and other high-technology industries. The Advanced Materials Handling, or AMH, segment develops solutions to monitor, protect, transport and deliver critical liquid chemistries, wafers and other substrates for a broad set of applications in the semiconductor industry, life sciences and other high-technology industries. While these segments have separate products and technical know-how, they share common business systems and processes, technology centers and strategic and technology roadmaps. With the technology, capabilities and complementary product portfolios from these three segments, we believe we are uniquely positioned to collaborate across divisions to create new, co-optimized and increasingly integrated solutions for our customers. For example, our SCEM segment offers a highly selective nitride etch chemistry, our MC segment provides a liquid filter that is specifically matched to that formulation and our AMH segment ensures the integrity of the product as it is moved to and through the fab environment.

We believe that our platform is differentiated and resilient for several reasons. First, approximately 70% of our revenue during 2020 was unit driven or recurring in nature, from products consumed as a result of the semiconductor manufacturing process. Our revenue is therefore generally more impacted by overall global semiconductor demand than the sales of semiconductor capital equipment. Second, our solutions are increasingly specified and tailored to meet our customers’ unique process conditions, and therefore switching away from our products may be costly and time-consuming and may introduce risk to manufacturing yields. Third, our product portfolio is broad and not overly concentrated on any single product or product platform. As of December 31, 2020, we offered over 15,000 standard and customized products, and in 2020 no single product platform represented more than 4% of our net sales. Fourth, our customer base is diverse, and we are not overly dependent on any one single customer. Our customers are represented across the semiconductor supply chain, from chemical manufacturers,

1

to equipment manufacturers, to semiconductor manufacturers. During 2020, only one customer accounted for over 10% of our net sales, while our top 10 customers accounted for approximately 46% of our net sales. Lastly, we believe our strong financial profile will allow us to invest in the research and development and advanced manufacturing capabilities necessary to maintain and expand our technology leadership and to drive organic growth. As we have done in the past, we expect to act as a consolidator in the industry, to expand upon our product portfolio, increase our scale and strengthen our position as a leading supplier to our customers.

THE SEMICONDUCTOR ECOSYSTEM

The manufacture of semiconductors requires hundreds of highly complex and sensitive manufacturing steps, during which a variety of materials are repeatedly applied to a silicon wafer to build integrated circuits on the wafer surface. We serve the semiconductor ecosystem by providing specialty materials and chemicals utilized in many process steps, offering a broad range of products to monitor, protect, transport and deliver these critical process materials during the manufacturing process and providing systems to purify liquid chemistry and gases throughout the manufacturing process. The areas of the semiconductor ecosystem that rely most heavily on our products and solutions are described below.

Etch and Resist Strip. During the etch process, specific areas of the thin film that have been deposited on the surface of a wafer are removed to leave a desired circuit pattern. After the etch process, the hardened resist needs to be completely removed, which requires the use of ultra-high purity chemicals of precise composition. In order to maintain manufacturing yields and avoid defective products, these chemicals must be maintained at very high purity levels without the presence of foreign material such as particles, ions or organic contaminants. Several of our products are utilized by semiconductor manufacturers during and after the etch process, including:

•Formulated chemical solutions to remove photoresists and post-etch residues;

•Filters and purifiers, which help to ensure the purity of cleaning chemistries and to achieve desired yields in the etch processing steps; and

•Precision-engineered coatings to provide barriers to corrosive chemistries in the etch environment, protect surfaces from erosion and minimize particle generation.

In addition to being utilized throughout the etch process, semiconductor manufacturers require ultra-high purity chemicals of precise composition to clean wafers before and after several of the processes described below. Our proprietary formulated cleaning chemistries are used in these wet cleaning processes, and our liquid filters and purifiers ensure the purity of these chemicals.

Deposition. Deposition is a process during which certain materials are transferred to the surface of a wafer. Deposition processes include physical vapor deposition, or PVD, where a thin film is deposited on a wafer surface in a low-pressure gas environment; chemical vapor deposition, or CVD, where a thin film is deposited on a wafer surface by exposing it to one or more volatile precursors which react with the wafer surface; atomic-layer deposition, or ALD, where a thin film is deposited on a wafer surface by exposing it to one or more precursors which react through a series of sequential, self-limiting reactions; and electro-plating, where a metal layer, such as copper, is deposited on a wafer surface using chemical baths. We provide products that are used during the deposition process that are critical to enabling new device architectures, ensuring device performance and achieving the targeted manufacturing yields of semiconductor manufacturers, including:

•Advanced precursor materials and electro-plating chemicals, which are utilized to meet the semiconductor industry’s composition, uniformity and thickness requirements of deposited films; and

•Filtration and purification products, which are used to remove contaminants during the deposition process, consequently reducing defects on wafers.

Photolithography. Photolithography is a process that uses light to print complex circuit patterns onto the wafer and is repeated many times throughout the semiconductor manufacturing process. To print the projected optical pattern, the wafer is coated with a thin film of light-sensitive material, called photoresist. Light is projected to expose the photoresist, which is then developed to create a stenciled image pattern. We offer products that semiconductor manufacturers use throughout the photolithography process, including:

•Liquid filtration and liquid packaging and dispense systems designed to ensure the pure, accurate and uniform dispense of photoresists onto the wafer, enabling manufacturers to achieve acceptable yields in the manufacturing process; and

•Gas microcontamination control systems designed to eliminate airborne contaminants that often disrupt effective photolithography processes.

2

Ion Implant. Ion implantation is a key technology for forming transistors and is used many times during semiconductor fabrication. During ion implantation, wafers are bombarded by a beam of electrically-charged ions which change the electrical properties of the exposed surface films. Those of our products that are used during the ion implant process include:

•Safe Delivery Source®, or SDS®, and Vacuum Actuated Cylinders, or VAC®, gas delivery systems designed to ensure the safe, effective and efficient delivery of the toxic gases necessary for the implant process; and

•Electrostatic chucks and proprietary low temperature plasma coating processes for core components, which are critical elements of ion implantation equipment.

Chemical Mechanical Planarization. Chemical mechanical planarization, or CMP, is a polishing process used by semiconductor manufacturers to planarize, or flatten, many of the layers of material that have been deposited on silicon wafers. We offer a broad range of products used by semiconductor manufacturers during and immediately following the CMP process, including:

•CMP slurry products, which are used for polishing ultra-hard surface materials, including silicon carbide, or SiC, and gallium nitride, or GaN, substrates;

•Formulated cleaning chemistries, which remove residue from wafer surfaces after the CMP process and prevent subsequent corrosion;

•Filtration and purification solutions, which are used to remove select particles and contaminants from slurries and cleaning chemistries that can cause defects on a wafer’s surface;

•Roller brushes, which are used in conjunction with our cleaning chemistries to clean the wafer after completion of the CMP process in order to prepare the wafer for subsequent operations; and

•Pad conditioners, which are used to prepare the surface of the CMP polishing pad prior to every polishing cycle.

Wafer Solutions. Our wafer and reticle carriers are high-purity “micro-environments” that carry wafers between manufacturing process steps. These products protect wafers from damage or abrasion and minimize contamination during transportation and automated processing. Front-end wafer processing can involve hundreds of steps and take several weeks. Protection of the processed wafer between steps is essential, as a batch of fully processed 200 mm or 300 mm wafers transported in one of our products can be worth over a million dollars.

Chemical Containers. Semiconductor manufacturing and other high-technology processes utilize large volumes of high-purity, corrosive and hazardous chemicals. We provide solutions for the handling of such chemicals, including:

•Ultra-high purity chemical container products, such as drums, flexible packaging and associated coded connection systems, which are designed to 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 semiconductor manufacturing process; and

•Ultra-pure valves, fittings, tubings and sensing and control products, which are used to distribute these chemicals around the fab and in wet process tools.

Other Markets. Many of the processes used to manufacture semiconductors are also used to manufacture flat panel displays, high-purity chemicals, solar cells, optical magnetic storage devices and light-emitting diodes, or LEDs, resulting in the need for similar filtration, purification, control and measurement capabilities. We seek to leverage our products, technologies, expertise and core capabilities to address these important market opportunities and pursue opportunities in certain life sciences applications.

INDUSTRY TRENDS

Emerging Applications. The market for semiconductors has grown significantly over the past few decades, and we expect this trend to continue. We believe that smartphones (including 5G), Internet of Things and emerging applications in cloud computing, machine learning and artificial intelligence, autonomous vehicles and virtual reality will drive growth in the demand for semiconductors, drive wafer starts and create significant opportunities for our products. Existing applications in data processing, wireless communications, broadband infrastructure, personal computers, handheld electronic devices and other consumer electronics are also expected to drive demand for semiconductors, and in turn, our products, especially in light of the increased prevalence of work-from-home and remote learning caused by the COVID-19 pandemic. For further information about our industries, see the “Risk Factors—Risks Related to Our Business and Industry” section of this Annual Report on Form 10-K, including under the heading “The industries we serve are constantly evolving, and any failure to manage our business effectively during periods of rapid change may adversely affect our business performance and results of operations.”

3

Manufacturing Complexity and Architecture. The emerging applications described above require more powerful, faster and more energy-efficient semiconductors. Semiconductor architectures are changing, with transistor design increasing in complexity, the use of multilayered patterning, vertical structures such as FinFET and 3D NAND, and shrinking dimensions. These advanced architectures require more process steps to manufacture semiconductors. We believe that demand for our materials and consumable products will benefit from the increase in process steps in lithography, deposition, CMP and etch and clean required to manufacture leading-edge semiconductors.

Additionally, new materials have played a significant role in enabling improved device performance, and we expect this trend to continue. As dimensions get smaller, new materials will be required to enable transistor connectivity. For example, leading-edge semiconductor manufacturers are moving towards atomic layer scale, where the precision of the manufacturing process and purity of the materials used is vital to maintain device integrity. These materials need to be supplied and delivered at ever-increasing levels of purity and control, from point-of-production to point-of-dispense on the wafer. We expect the trend for new materials supplied at high levels of purity to drive the demand for our advanced materials and our products and solutions designed to purify, monitor, protect, transport and deliver critical materials. To address the challenges related to advanced technology nodes, we collaborate with our customers to develop new materials, to enhance our filtration and purification capabilities and to introduce advanced materials packaging and monitoring capabilities.

Materials Handling Solutions. To minimize the potential for damage or degradation to their materials and to protect their investment in processed wafers, our semiconductor customers have become increasingly focused on materials handling solutions that enable them to safely store, handle, process and transport critical materials throughout the manufacturing process. We believe that this trend provides opportunities for us to utilize our breadth of capabilities to provide innovative materials management, purification, wafer transport and process solutions to semiconductor customers to enable them to successfully manage this growing complexity.

Reliance on Trusted Suppliers. Our customers require that their key materials suppliers demonstrate greater capabilities and efficiencies in their processes, including sustainability, scalability, flexible manufacturing, quality control, supply chain management and the ability to effectively collaborate on solutions to problems. We have responded to these demands by deploying resources in strategic locations to enable us to align with customer requirements and drive operational excellence. For example, in 2016 and 2017, we expanded our technology centers in South Korea and Taiwan, and in 2019, we opened a technology center in China, containing application and analytical labs, adding to our research and development capabilities to enhance local development and collaboration and to strengthen relationships with our key customers. We believe that, as semiconductor manufacturers require greater capabilities of their supply partners, we will be able to leverage our manufacturing, operational and technical capabilities, along with our broad technology portfolio and expanding scale, to become an increasingly important strategic supplier to our customers.

Continued Consolidation. Our customer base within the semiconductor industry has consolidated in recent years through mergers and acquisitions. As a result, the importance of maintaining and developing strong and close relationships with our customers becomes even more essential. While continuing to strengthen these relationships, we also seek to further broaden our customer base by leveraging our products, technologies, expertise and core capabilities in serving semiconductor applications to address adjacent market opportunities, including in manufacturing processes for flat panel displays, high-purity chemicals, solar cells, optical magnetic storage devices, LEDs and products for life sciences applications. For further information, see the “Risk Factors—Risks Related to Our Business and Industry” section of this Annual Report on Form 10-K under the heading “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 lost one or more of these customers.”

OUR COMPETITIVE STRENGTHS

Strong Technology Portfolio. In the highly competitive semiconductor industry, manufacturers seek partners that are applications experts with broad technology portfolios to collaborate from product conception to high volume manufacturing. To that end, we are committed to being able to provide our customers with innovative solutions for their manufacturing needs. For example, we have introduced sub-10 nanometer and 7 nanometer filtration products, advanced deposition materials for next generation transistor and interconnect technologies, advanced reticle pods for extreme ultra-violet, or EUV, photolithography applications, advanced 300 mm wafer carriers and advanced coatings to meet the rigorous demands related to the manufacturing of advanced technology nodes faced by our customers. Given the competitive nature of the semiconductor industry, we continuously seek to engage with leading logic and memory manufacturers to further advance their technology roadmaps.

Comprehensive and Diverse Product Offerings. As semiconductor manufacturers are driving towards more advanced technology nodes, our customers are seeking suppliers that can provide a broad range of customized, reliable, flexible and cost-effective products and materials, as well as the technological and application design expertise necessary to enhance their

4

productivity, quality and yield. We believe our comprehensive offering of materials and products creates a competitive advantage as it enables us to meet a broad range of customer needs and provide a single source of product offerings for semiconductor device and equipment manufacturers, which can often translate to shorter time-to-solution and time-to-market for our customers. Additionally, our broad product and solution portfolio allows us to serve many aspects of the semiconductor manufacturing ecosystem and to create synergies among some of our products. For example, our highly selective nitride etch formulations used in 3D NAND applications have been co-developed with specifically functionalized filter membranes designed to ensure the highest process performance. Additionally, our sensing technology detects active components in the etch chemistry and allows customers to control the bath lifetime.

To further strengthen and improve our product offerings, we are committed to significant investment in research and development initiatives, having spent approximately $136.1 million, $121.1 million and $118.5 million on such activities in 2020, 2019 and 2018, respectively, representing 7.3%, 7.6% and 7.6% of our net sales, in 2020, 2019 and 2018, respectively. Our research and development expenditures have been increasingly directed towards innovation for advanced technology nodes, and in 2020, a significant portion of our research and development expenditures were focused at the leading edge.

Global Infrastructure. Complementing our strong technology portfolio and diverse product offerings, we have a global infrastructure of design, manufacturing, logistics, distribution, service and technical support facilities to meet the needs of our global customers. For example, during 2020 we announced our plan to expand our manufacturing presence in Taiwan, and we expect to start construction on a new manufacturing facility, which we expect will be our largest such facility in the world, in that country during 2021. We expect that it will begin initial operations in late 2021 and ramp to full production in subsequent phases. The new Taiwan facility will add to recent expansions of and investments in our manufacturing operations and advanced technology centers in Taiwan and South Korea designed to support our customers in these regions. Further, we have established or acquired new facilities in China to serve the semiconductor manufacturing base in that country, expanded manufacturing capacity in Malaysia and expanded our presence in Singapore to enhance our global and regional management of supply chain and manufacturing processes. For more information on our advanced manufacturing capabilities, see the “—Manufacturing” section below. We service our customer relationships in Asia, North America, Europe and the Middle East predominantly via direct sales and support personnel and to a lesser extent through selected independent sales representatives and distributors.

Our expansive global presence allows us to meet our customers where they operate, which has enabled us to build strong relationships with them. Our customers include logic and memory semiconductor manufacturers, original equipment manufacturers, or OEMs, and semiconductor materials suppliers. These customer relationships provide us with significant collaboration opportunities at the early product design stage, which facilitate our ability to introduce new products and applications. For example, we work with our key customers in the development of advanced manufacturing processes to identify and respond to their requests for current and future generations of products for emerging applications requiring cleaner materials. Similarly, we also collaborate with our customers to develop systems that maintain the integrity and stability of materials during transport and through the manufacturing process. We believe that our customer base will continue to be an important source of new product development opportunities. Due to the specialized nature of our products, manufacturing complexity, qualification requirements in customers’ fabrication processes, high customer re-formulation and qualification change costs and extensive proprietary products, we believe our supply position with our customers is strong.

Operational Excellence. Our customers are increasingly focused on the effectiveness, dependability and consistency of their supply chains. We remain committed to operational excellence and are especially focused on the following priorities that we believe enable us to perform at the high level that our customers expect.

•Use of manufacturing equipment and facilities incorporating leading-edge technology, including advanced cleanroom and cleaning procedures. As our customers introduce more complex architectures and search for new materials with better electrical and structural properties to improve the performance of their devices, our equipment, technology and processes must evolve to keep pace. In response, we have invested heavily in leading-edge manufacturing facilities, which are in strategic regions throughout the world. With our global presence, we are able to efficiently utilize our portfolio of manufacturing facilities to meet our customers’ needs quickly and efficiently.

•Implementation of automated manufacturing, quality and supply chain management systems. In recent years, we have made significant investments in quality systems to help drive automation of our processes. During this time, we have implemented standardized manufacturing systems to stress optimization of equipment effectiveness, predictive maintenance and direct labor productivity, automated quality systems that provide both process monitoring and statistical process control throughout the manufacturing process as well as predictive quality data to mitigate against potential quality deficiencies and supply chain management systems designed to ensure a reliable and responsive supply of high-quality raw materials. These systems generate large amounts of data, which we utilize to further enhance our quality, productivity and stability. Our focus on quality is evidenced by our sigma level moving from less than four in 2010 to greater than five in 2020, which represents a significant improvement in quality performance and

5

reduction in defective parts produced. In addition, over the last several years we have earned awards from our customers for our performance and focus on continuous improvement.

•Maintaining an agile manufacturing organization. Our manufacturing workforce is capable of the rapid design and development of prototypes of new and derivative products, as well as promptly responding to customer feedback concerning prototypes so that we can quickly commercialize and ramp our production within very tight process windows required by our customers. We believe that our focus on disciplined execution and timeliness in customer interactions enables us to build even deeper connections with our customers, which in turn allows us to further understand their technical roadmaps and to help them overcome technical hurdles.

OUR BUSINESS STRATEGY

We intend to build upon our position as a leading supplier of advanced materials and process solutions for the semiconductor and other high-technology industries to expand our core business and to grow in other high value-added manufacturing process markets. Our strategy includes the following key elements:

Commitment to Technology Leadership. We seek to continuously improve our products and develop new products as our customers’ needs evolve. As semiconductor devices become smaller and more powerful and new materials and processes are deployed to produce them, we seek to expand our technological capabilities by developing advanced products that address our customers’ requirements for greater purification, protection and transport of high value-added materials and by developing advanced materials for use in critical fabrication processes.

Leveraging Our Expertise. We leverage our broad expertise across our portfolio of advanced materials, materials handling and purification capabilities to create innovative and new solutions to address unmet customer needs. For example, our industry-leading post-CMP cleaning chemistry is developed and manufactured by our SCEM segment, with collaboration from our MC segment, packaged with our ultra-clean container and connector system made by our AMH segment, and delivered to the process tools through fluid handling systems also made by our AMH segment. Furthermore, in process tools, these chemistries may go through one or several purification systems produced by our MC segment to eliminate particles and contaminants. Similarly, our advanced deposition materials business requires comprehensive capabilities across a number of disciplines, including the synthetization of unique molecules, specialized knowledge of how to purify these materials and the capability to safely transport these materials and deliver them onto the wafer at a high throughput. We seek to utilize our expertise in areas of strategic and increasing importance to semiconductor manufacturers, such as developing advanced materials and ensuring the purity of high-value materials, and our ability to work collaboratively across our three segments enables us to quickly and effectively develop optimized and complementary solutions for our customers.

Operational Excellence. Our strategy is to continue to develop our advanced manufacturing capabilities into a competitive advantage with our customers by conducting our manufacturing operations in a manner that ensures the safety of our employees and of the individuals using our products and by continuing to focus on the other priorities noted in the “—Our Competitive Strengths—Operational Excellence” section above.

Continued Focus on Customers. We view the strong relationships we have with our customers, which include leading logic and memory semiconductor manufacturers, OEMs and semiconductor materials suppliers, as critical to our long-term success. We intend to reinforce and further strengthen these relationships through, among other things, collaborations and joint development. Customer intimacy enables us to respond rapidly and thoroughly to their manufacturing challenges and enables us to bring forth new products that serve existing needs.

Safety. A core component of our strategy is our intense focus on the safety of our employees and of the individuals using our products. With respect to employee safety, we have put in place proactive programs designed to build a culture of safety in our facilities. And while the well-being of our employees is always at the top of our mind, we also design our products with an eye towards the safety of the people who are using them. To illustrate, our Aramus high-purity bags for biologics are designed to withstand cryogenic temperatures and to not break down in extremely cold environments. By reducing ruptures during transportation, our bags enable the effective distribution of vaccines, including those that may be used in the battle against the COVID-19 pandemic, which may allow quicker access to a vaccine when compared to the use of traditional technologies. Also, our Safe Delivery Source products are designed to minimize potential leaks during transportation and use of hazardous gases, features which provide significant safety, environmental and productivity benefits over traditional high-pressure cylinders.

Adjacent Markets. We leverage the expertise that we have gained from serving the semiconductor industry to develop products for other industries that employ similar technologies and production processes and that utilize materials integrity management, high-purity fluids and integrated dispense systems. For example, outside of the semiconductor industry our products are used in manufacturing processes for flat panel displays, high-purity chemicals, solar cells, optical magnetic storage devices, LEDs and products for life sciences and aerospace applications. We plan to continue to identify and develop products that address needs in adjacent markets. We believe that by utilizing our technology and core capabilities to provide solutions

6

across multiple industries, we are able to increase the total available market for our products and increase our return on R&D investments.

Strategic Acquisitions, Partnerships and Related Transactions. We will continue to pursue strategic acquisitions and business partnerships that enable us to address gaps in our product offerings, secure new customers, diversify into complementary product markets, broaden our technological capabilities and product offerings, access local or regional markets and achieve benefits of increased scale. For example, we strengthened and broadened our specialty chemicals and engineered materials product offerings while also addressing gaps in our portfolio when we acquired Sinmat, Inc., or Sinmat, in 2020 (CMP slurries) and Digital Specialty Chemicals, or DSC, and MPD Chemicals, or MPD, in 2019 (specialty chemicals). Similarly, we made several targeted acquisitions to diversify and expand our filtration and purification portfolio with the acquisitions of Hangzhou Anow Microfiltration Co., Ltd., or Anow, in 2019, the SAES Pure Gas business from SAES Getters S.p.A. in 2018, and the water and chemical filtration product line for microelectronics applications from W. L. Gore & Associates, Inc. in 2017. Finally, we added a suite of analytical instruments utilized in chemistry management and monitoring in semiconductor manufacturing processes to our product portfolio with our acquisitions of Global Measurement Technologies, Inc. in 2020 and Particle Sizing Systems, LLC in 2018. Our 2014 acquisition of ATMI, Inc., or ATMI, serves as an example of a strategic transaction that significantly increased our scale, as the acquisition brought a whole new portfolio of technologies and materials products to serve our semiconductor customers. Further, as the dynamics of the markets that we serve shift, we will reevaluate our existing businesses and may decide to restructure or replace one or more businesses, such as the sale of our small cleaning business in France in 2018 and exiting our small cleaning business in Taiwan in 2020. Finally, we regularly evaluate opportunities for strategic alliances, such as our strategic alliance with Enthone, joint development programs and collaborative marketing efforts with key customers and other industry leaders. For example, in 2017, we entered into agreements with local partners to expand our capability to manufacture certain specialty chemical and deposition products locally and shorten our supply chain for our customers in China.

OUR SEGMENTS

Our business is organized and operated in three segments which align with the key elements of the advanced semiconductor manufacturing ecosystem: Specialty Chemicals and Engineered Materials, or SCEM; Microcontamination Control, or MC; and Advanced Materials Handling, or AMH. We leverage our expertise from these three segments to create new and increasingly integrated solutions for our customers. The following is a detailed description of our three segments.

SPECIALTY CHEMICALS AND ENGINEERED MATERIALS SEGMENT

The SCEM segment provides high-performance and high-purity process chemistries, gases and materials that enhance our customers’ product performance. These materials are utilized in critical semiconductor manufacturing processes such as deposition, cleaning and integration of complex process materials. Advanced materials, delivered at high purity, are critical to enabling the performance of leading-edge logic and memory applications.  We believe the growing demand in the 3D NAND market, challenges with metallization schemes and the need for specialized cleaning solutions will drive demand in our SCEM segment. In conjunction with products from our MC and AMH segments, the materials that our SCEM segment produces provide unique solutions to safely and efficiently deliver critical materials to support semiconductor and other advanced manufacturing processes. In addition, certain of the materials that our SCEM segment provides allow for enhanced product performance for our customers in aerospace, medical, pharmaceuticals and other high-technology intensive material segments.

Specialty Gas Products. Our specialty gas solutions provide advanced safety and process capabilities to semiconductor, display and solar panel manufacturers. Our SDS cylinders store and deliver hazardous gases, such as arsine, phosphine, germanium tetrafluoride and boron trifluoride, at sub-atmospheric pressure through the use of our proprietary carbon-based adsorbent materials. These products minimize potential leaks during transportation and use and allow more gas to be stored in the cylinder, features which provide significant safety, environmental and productivity benefits over traditional high-pressure cylinders. New generations of SDS products further increase the gas storage capacity, reducing tool down time and thereby generating significant cost savings for our customers. We also offer VAC, a complementary technology to SDS, where select implant gases and gas mixtures are stored under high pressure but are delivered sub-atmospherically.

Specialty Materials Products. Our specialty materials include specialized graphite, silicon carbide and a variety of unique, high purity coatings for dry or plasma etch, chemical vapor deposition and ion implant applications. Our POCO® premium graphite is used to make precision consumable electrodes for electrical discharge machining, hot glass contact materials for glass product manufacturing and forming and other consumable products for various industrial applications, including aerospace, optical, medical devices, air bearings and printing. Our high-performance specialty coatings, such as our Pegasus™ and Cearus™ coatings, provide erosion resistance, minimize particle generation and prevent contamination on critical components in semiconductor environments and other high-technology manufacturing operations. Our specialty materials provide customized solutions for applications challenged with unique temperature, corrosive, chemical or process

7

environments, such as electrostatic chucks used to hold wafers during processing, plasma etch chamber components, aircraft bearings and ultrasonic transducers.

Advanced Deposition Materials Products. Our advanced deposition materials include advanced liquid, gaseous and solid precursors that are incorporated in CVD and ALD processes by the semiconductor industry, including organometallic precursors for the deposition of tungsten, titanium, cobalt and aluminum containing films and organosilane precursors for the deposition of silicon oxide and silicon nitride films. These precursors are designed in close collaboration with OEM process tool manufacturers and device makers to produce application specific solutions that are compatible with complex integrations of material solutions used to build the semiconductor device. We offer delivery systems and containers that allow for reliable storage and delivery of low volatility solid and liquid precursors required in ALD processes. When combined with our proprietary corrosion-resistant coatings and filtration solutions from our MC segment, our advanced deposition materials enable the industry’s highest purity levels, resulting in improved device performance.

Surface Preparation and Integration Products. We offer a range of materials used to prepare the surface of a semiconductor wafer during the manufacturing process and to integrate with materials being used on the wafer. We offer a broad range of cleaning solutions for applications such as semiconductor post-etch residue removal, wafer etching, organics removal, negative resist removal, edge bead removal and corrosion prevention. Our wet chemistries solutions, combined with filtration solutions from our MC segment and fluid handling solutions from our AMH segment, provide enhanced purity, which results in improvements in our customers’ processes. Our consumable polyvinyl alcohol (PVA) roller brush products are used to clean the wafer following the CMP process, and our pad conditioners, based on our silicon carbide capabilities, lengthen CMP pad life. Through the acquisition of Sinmat, we now offer slurry products used for polishing ultra-hard surface materials, including SiC and GaN substrates, which are utilized in the power electronics and advanced communications end-markets. We also provide advanced plating solutions, such as our Viaform® product (a trademark of and exclusively licensed from Element Solutions, Inc.), which includes inorganic and proprietary organic molecules that provide the wiring for copper interconnects.

Specialty Chemicals. Our specialty chemicals include advanced liquid and solid materials, which are used in a range of high-performance material applications ranging from medical devices to materials used in semiconductor applications. Our product solutions include organometallic and organosilane materials used in semiconductor device manufacturing, monomers and polymers used in the manufacture of medical devices, polyolefin catalysts used in the manufacture of polyethene and polypropylene, chromic materials used in security dyes and inks, isotopic ally labeled materials used in clinical diagnostics and a range of materials used in the manufacture of pharmaceutical ingredients. In addition, our specialty chemicals business provides materials to a number of our other businesses to enable advanced performance of final product solutions.

MICROCONTAMINATION CONTROL SEGMENT

The MC segment offers solutions to purify critical liquid chemistries and process gases used in semiconductor manufacturing processes and other high-technology industries. The design and performance of our liquid and gas filtration and purification products are important to the semiconductor manufacturing process because they remove contamination, directly reduce defects, improve manufacturing yield and enhance the long-term reliability of the semiconductor device. Our proprietary filters remove organic and inorganic nanometer-sized contaminants from the different fluids and gases used in the manufacturing process, including photolithography, deposition, planarization and surface etching and cleaning. As our customers leverage leading-edge lithography tools and multi-patterning technology to enable each subsequent generation of products, our filtration and purification products are utilized to achieve necessary levels of purity and contamination control. We believe demand for purification and filtration products is being driven by the continuous node shrink in logic semiconductors and the ramp in the 3D NAND market, as the risk of yield loss grows with the incremental manufacturing steps needed for the production of these devices. We utilize expertise from the AMH segment in polymer science and from the SCEM segment in cleaning chemistries to develop differentiated filtration and purification solutions for our customers.

Liquid Microcontamination Control Products. We offer a variety of products that control contaminants in our customers’ wet processes. For example, our Torrento® series of filters is used for the filtration of aggressive acid and base chemistries for both semiconductor fabs as well as specialty chemical manufacturers, including our SCEM segment. Manufacturers of high purity chemicals and semiconductor fabs use our Trinzik® and Microgard™ products for the filtration of chemicals and ultra-pure water. Our Impact® series of filters are used in point-of-use photochemical dispense applications, including those provided by our AMH segment, where the delivery of superior flow rate performance and reduced microbubble formation is critical. Our Protego® series of liquid purifier/filter products are used to reduce metallic contamination in chemical manufacturing and in critical wafer rinsing and drying applications by our customers. In addition, we provide membrane and liquid filtration offerings serving semiconductor, pharmaceutical and medical applications.

Gas Microcontamination Control Products. We offer a broad portfolio of products designed to remove particulate and molecular contaminants from controlled environments and gas streams in semiconductor, flat panel display and LED fabs.

8

wide gas purification systems provide continuous purified gas supply to customer fabs from the point of creation on the gas pads to the point-of-use at the wafer by chemically reacting and absorbing contaminants, effectively removing gaseous contaminants down to part-per-trillion levels. Our Chambergard™ gas diffusers provide semiconductor equipment manufacturers with the capability to rapidly vent their tools to atmosphere to dramatically reduce process cycle times without adding particles to the wafers. In addition, our Vaporsorb products are used to eliminate airborne molecular contamination from critical process tool areas or cleanrooms in the fab. These products are used in or alongside critical processing tools to improve yield and reduce tool downtime.

ADVANCED MATERIALS HANDLING SEGMENT

The AMH segment develops solutions to monitor, protect, transport and deliver critical liquid chemistries, wafers and substrates for a broad set of applications in the semiconductor and other high-technology industries. These systems and products improve our customers’ yields by protecting wafers from abrasion, degradation and contamination during manufacturing and transportation and by assuring the consistent, clean and safe delivery of advanced chemicals from the chemical manufacturer to the point-of-use in the semiconductor fab. The AMH segment collaborates closely with our SCEM segment in developing products that are compatible with advanced chemistries to enhance yields and integrates liquid filtration technology from our MC segment to deliver consistent and pure chemistry.

Microenvironment Solutions. We lead the market with our high-volume line of Ultrapak® and Crystalpak® products for wafers ranging from 100 to 200 mm, which ensure the clean and secure transport of wafers from the wafer manufacturers to the semiconductor fabs. We also offer a front-opening shipping box, or FOSB, for the transportation and automated interface of 300 mm wafers. We lead the market for 300mm front-opening unified pods, or FOUPs, wafer transport and process carriers and standard mechanical interface pods, or SMIF pods, for 200mm wafer applications. These microenvironment products safely and accurately deliver wafers within the semiconductor fab environment to the various process fabrication steps. We are a leader in reticle protection products for photolithography, including products that protect the high-value EUV lithography masks during both the mask manufacturing process and their use in the semiconductor fab.

Fluid Management Products. We offer various fluid management products that cover a range of applications, including liquid packaging, fluid handling and process monitoring products. Our broad portfolio of flexible and rigid polymer packaging and container products, from low-volume containers to transport high-value photoresist chemistries, such as our NOWPak® products, to large intermediate bulk containers allow our customers to safely and efficiently transport chemicals in bulk, such as our FluoroPure® products. Our connection systems provide safe and efficient chemical dispense from the container to the fab. Chemical companies utilize our packaging products to ensure the purity of chemistries shipped to semiconductor fabs, resulting in enhanced yields.

In addition, we are a leader in high-purity fluid transfer products such as valves, fittings, tubing, pipe, custom fabricated products and associated connection systems, such as our PrimeLock® connections, for high-purity chemical applications and our proprietary digital flow control technology improving the uniformity of chemicals applied on wafers. Our IntelliGen® integrated, high-precision liquid dispense systems enable the uniform application of advanced chemistries during the wafer fabrication process, integrating our valve control expertise with filter device technologies from our MC segment, in order to conserve high-value chemistry and reduce defects on wafers. Our comprehensive product lines provide our customers with a single-source provider for their high-purity chemical management needs throughout the manufacturing process.

Notable competitors with respect to certain specific product areas include Pall Corporation (part of Danaher Corporation), Shin-Etsu Polymer Co., Ltd., Gemu Valves, Inc., Tokyo Keiso Co., Ltd., Mersen, the EMD Performance Materials division of Merck KGaA, E. I. du Pont de Nemours, Company, Air Liquide, Praxair, Inc. (a subsidiary of Linde plc.), Donaldson Company, Inc. and Parker Hannifin Corp.

ENGINEERING, RESEARCH AND DEVELOPMENT

We believe that technology is important to the success of our businesses, and we plan to continue to devote significant resources to engineering, research and development, or ER&D, balancing efforts between shorter-term market needs and longer-term investments. As of December 31, 2020, we had approximately 1,100 employees in ER&D. We have supplemented and may continue to supplement our internal research and development efforts by licensing technology from third parties and/or acquiring rights with respect to products incorporating externally owned technologies. Our R&D expenses consist of personnel and other direct and indirect costs for internally funded project development, including the use of outside service providers.

We believe we have a rich pipeline of development projects. Our ER&D efforts are directed toward developing and improving our technology platforms for semiconductor and advanced processing applications and identifying and developing products for new applications, often working directly with our customers to address their particular needs.

We have ER&D capabilities in the United States, Canada, China, Japan, South Korea, Taiwan, Singapore and Malaysia to meet the global needs of our customers. We use sophisticated methodologies to research, develop and characterize our materials and products. Our capabilities to test and characterize our materials and products are focused on continuously reducing risks and threats to the integrity of the critical materials that our customers use in their manufacturing processes.

In addition, we collaborate with leading universities and industry consortia, such as the University of California, Yale University, Pennsylvania State University, the Interuniversity Microelectronics Center (imec®) and CEA-LETI. We undertake this work to extend the reach of our internal R&D and to gain access to leadership ideas and concepts beyond the time horizon of our internal development activities.

PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS

As of December 31, 2020, we own approximately 2,520 active patents worldwide, of which about 650 are United States patents. Additionally, we own about 1,050 pending patent applications globally. In addition, we license certain patents owned by third parties. We rely on a combination of patent, copyright, trademark and trade secret laws and license agreements to establish and protect our proprietary rights. We seek to refresh our intellectual property on an ongoing basis through continued innovation. While we license and expect to continue to license technology used in the manufacture and distribution of products from third parties, we do not consider any particular patent or license to be material to our business.

We vigorously protect and defend our intellectual property. We require each of our employees, including our executive officers, to enter into agreements with us pursuant to which the employee agrees to keep our proprietary information confidential and to assign to us inventions made during the course of employment. We also require outside scientific collaborators, sponsored researchers and other advisors and consultants who are provided confidential information to execute confidentiality agreements with us. These agreements generally provide that all confidential information developed or made known to the entity or individual during the course of the entity’s or individual’s relationship with the Company is to be kept confidential and not disclosed to third parties except in specific limited circumstances.

MANUFACTURING

Our customers rely on our products and materials to ensure the integrity of the critical materials used in their manufacturing processes by providing purity, cleanliness, consistent performance, dimensional precision and stability. Our ability to meet our customers’ expectations, combined with our substantial investments in worldwide manufacturing capacity, position us well to respond to the increasing demands from our customers for yield-enhancing materials and solutions.

To meet our customers’ needs worldwide, we have established an extensive global manufacturing network with facilities in the United States, Canada, Japan, Taiwan, Malaysia, South Korea and China.

membrane casting;	assembly.
cartridge manufacturing and assembly;

We have made significant investments in systems and equipment to create innovative products and tool designs, including metrology and 3D printing capabilities for rapid analysis and prototype production. In addition, we use contract manufacturers for certain of our products both in the United States and Asia.

RAW MATERIALS

Our products are made from a wide variety of raw materials that are generally available from multiple sources of supply. While we seek to have several sources of supply for raw materials, certain materials included in our products, such as certain filtration membranes in our MC segment, petroleum coke and specialty and commodity chemicals in our SCEM segment and certain polymer resins in our AMH segment, are obtained from a single source or a limited group of suppliers or from suppliers in a single country. We have entered into multi-year supply agreements with a number of suppliers for the purchase of raw materials in the interest of supply assurance and to control costs.

GOVERNMENTAL REGULATION

Our operations are subject to federal, state and local regulatory requirements relating to environmental, waste management and health and safety matters, including measures relating to the release, use, storage, treatment, transportation, discharge, disposal and remediation of contaminants, hazardous substances and wastes, as well as practices and procedures applicable to the construction and operation of our plants. Although some risk of costs and liabilities related to these matters is inherent in our business, as with many similar businesses, we believe that our business is operated in substantial compliance with applicable regulations. However, new, modified or more stringent requirements or enforcement policies could be adopted, which could adversely affect us. While we expect that capital expenditures will be necessary to ensure that any new manufacturing facility is in compliance with environmental and health and safety laws, we do not expect these expenditures to be material.

HUMAN CAPITAL RESOURCES

We believe that our employees are a critical asset in achieving our mission of helping our customers improve their productivity, performance and technology by providing solutions for the most advanced manufacturing environments. In order to attract and retain top talent, we are focused on creating a diverse, inclusive and safe workplace and are committed to providing quality development and training opportunities for our employees.

As of December 31, 2020, we had approximately 5,800 employees, of whom approximately 52%, 17%, 9%, 8%, 6%, 5% and 3% are located in North America, Taiwan, South Korea, Japan, China, Europe and Southeast Asia, respectively. Given the variability of business cycles in the semiconductor industry and the quick response time required by our customers, it is critical that we be able to quickly adjust the size of our production staff to maximize efficiency. Therefore, we use skilled temporary labor as required. None of our employees is represented by a labor union or covered by a collective bargaining agreement other than statutorily mandated programs in certain international jurisdictions.

Diversity and Inclusion. We believe that maintaining a culture of diversity and inclusion helps enable us to innovate more effectively. To that end, we seek to promote diverse perspectives throughout our organization and are an equal opportunity employer committed to making employment decisions without regard to race, religion, national or ethnic origin, sex, sexual orientation, gender identity or expression, age, disability, protected veteran status or other characteristics protected by law.

Our commitment to diversity and inclusion is evidenced by the creation and support of our Employee Networks, which are networks of our employees who share a common interest and are designed to advance diversity and inclusion and to promote our workplaces as environments where all individuals are valued for their talents and empowered to reach their fullest potential. As of December 31, 2020, our Employee Networks included groups focused on gender identity, sexual orientation, age and veteran status.

Health, Safety and Wellness. Our success depends on the well-being of our employees. We maintain a culture focused on safety and strive to identify, eliminate and control risk in the workplace in an effort to prevent injury and illness. Our employees

12

have access to a global safety management system and are encouraged to report incidents, near misses or other observations in the system. The system has been widely adopted in our manufacturing locations across the globe, and management uses the information generated by it to set safety-related policies and to set goals for future performance. Further, we provide our employees with a comprehensive benefits package that includes health insurance and other resources that support their physical and mental well-being.

In response to the COVID-19 pandemic, commencing in the first quarter of 2020, we have taken, and we continue to take, proactive, aggressive actions to protect the health and safety of our employees, customers, partners and suppliers. We enacted rigorous safety measures, including social distancing protocols, encouraging employees who do not need to be physically present on the manufacturing floor or in a lab to perform their work to work from home, suspending non-essential travel, implementing temperature checks and other access controls at the entrances to our facilities, extensively and frequently disinfecting our workspaces and providing masks to employees who are physically present at our facilities. We expect to continue to implement these measures until the COVID-19 pandemic is adequately contained, and we may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees, customers, partners and suppliers.

Talent Development and Training. We are committed to the continued development and training of our employees. We conduct formal evaluations with each of our employees on an annual basis, and managers provide feedback directly to employees through informal review sessions periodically throughout the year. Our formal evaluation process requires employees to track whether they met certain development goals that are set at the beginning of the review period. We seek to provide opportunities for our employees to grow their careers and regularly fill open vacancies with internal candidates. In addition, management periodically assesses succession planning for certain key positions and reviews our workforce to identify high potential employees for future growth and development.

We also provide formal and informal training opportunities for our employees covering a variety of professional, technical and leadership topics. Our training opportunities are designed to promote learning across all levels of our organization, and in 2020 our formal training offerings included courses in leadership, project management and technical communications.

For more information, see “Cautionary Statement” in Item 7 of this Annual Report on Form 10-K.

Risks Related to Our Business and Industry

The COVID-19 pandemic and ensuing governmental responses could materially adversely affect our financial condition and results of operations.

As a result of the COVID-19 pandemic, governmental authorities have implemented and are continuing to implement numerous and constantly evolving measures to try to contain the virus, such as travel bans and restrictions, masking recommendations and mandates, limits on gatherings, quarantines, shelter-in-place orders and business shutdowns. We have important manufacturing operations in the United States, Japan, Korea, China, Malaysia and Taiwan, all of which have been affected by the outbreak and have taken measures to try to contain it. Measures providing for business shutdowns have generally excluded certain essential services, and those essential services have commonly included critical infrastructure and the businesses that support that critical infrastructure. While all of our facilities currently remain operational, these measures have impacted and may further impact our workforce and operations, as well as those of our customers, suppliers and other third parties with which we do business. For example, in March 2020 the government of Malaysia issued an order that significantly reduced the number of employees who could be physically present to operate our Malaysian plant, which temporarily reduced the productivity of that plant. The government of Malaysia issued a similar order restricting movement throughout that country in January 2021, which has not impacted our operations as of the date of this filing but may do so in the future. In addition to reduced productivity, the constraints and limits imposed on our operations may slow or diminish our research and development and customer qualification activities. During 2020, we experienced brief interruptions in operations at our sites in Hangzhou, China, San Luis Obispo, California and Bedford, Massachusetts and so far during 2021, we have experienced minor interruptions in our operations at our site in San Luis Obispo, California and a brief construction delay to an expansion of our facility in Toronto, Canada. Although many governmental measures have had specific expiration dates, some of those measures have already been extended more than once, and some governmental re-opening plans have been delayed or reversed due to spikes in the number of infections in the local area.

In addition, such measures have not effectively reduced the high rate of spread of the virus in certain locations and there may be additional waves of infection in the future, which could be more contagious than prior waves. For example, in December 2020 a new variant of the coronavirus was discovered in the United Kingdom that scientists believe is significantly more transmissible than variants previously encountered. As a result, there is considerable uncertainty regarding the duration, extent and effectiveness of current and future measures to contain the spread of the virus. Restrictions on our manufacturing, support operations or workforce, or similar limitations for our suppliers, could cause us to increase our safety stock of certain materials, limit our ability to meet customer demand and could have a material adverse effect on our financial condition and results of operations. Furthermore, restrictions or disruptions of transportation, such as reduced availability of air transport, port closures and increased border controls or closures, have in certain instances resulted in higher costs and delays both in obtaining materials and shipping finished goods to customers. Although to date these restrictions have not had a material adverse impact on our operations, they have placed considerable strain on us, our suppliers and other third parties with which we do business. There can be no assurance that these restrictions will not materially adversely affect our operations or those of our suppliers or the other third parties with which we do business in the future. If these restrictions and disruptions continue, they could slow production, impact our R&D efforts, harm our profitability, make our products less competitive or cause our customers to seek alternative suppliers.

In response to these developments, we have modified our business practices, including restricting employee travel, modifying employee work locations, implementing social distancing and enhanced sanitary measures in our facilities and cancelling attendance at events and conferences. Many of our suppliers and service providers have made similar modifications. The resources available to employees working remotely may not enable them to maintain the same level of productivity and efficiency, and employees may face additional demands on their time, such as increased responsibilities resulting from school closures or the illness of family members. While we have experienced only limited absenteeism from employees who are required to be on-site to perform their jobs, absenteeism may increase in the future and may harm our productivity. In addition, we have incurred and may continue to incur incremental employee compensation related to the COVID-19 pandemic. For example, since April 2020, we have awarded certain of our employees who are required to physically report to a manufacturing

14

facility in order to perform their jobs during the COVID-19 crisis with a special appreciation bonus for their efforts in sustaining our production continuity. Further, the increased reliance on remote access to information systems by us and our customers, suppliers and other third parties with which we do business increases the risk of exposure of our information and systems to potential cybersecurity breaches. We may take further actions with respect to COVID-19 as government authorities require or recommend or as we determine to be in the best interests of our employees, customers, partners and suppliers. There is no certainty that any such measures will be sufficient to mitigate the risks posed by the virus, in which case our employees may become sick, our ability to perform critical functions could be harmed and we may be unable to respond to the needs of our global business. The resumption of normal business operations after such interruptions may be delayed or constrained by lingering effects of COVID-19 on our suppliers, third-party service providers and/or customers.

The degree to which COVID-19 impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of outbreaks, their severity, potential additional waves of infection, the emergence of more virulent or more dangerous strains of the virus, the actions to mitigate the virus and its impact, the development, distribution, efficacy and acceptance of vaccines and how quickly and to what extent normal economic and operating conditions can resume. The prolonged implementation, or re-implementation, of measures by governments to try to contain the virus may lead to fatigue in complying with COVID-19 restrictions among the public, which in turn may further exacerbate its spread. Furthermore, the COVID-19 pandemic makes it more difficult for us to forecast demand and provide guidance for upcoming periods. Accordingly, any guidance we provide is likely to be less reliable than usual, and actual results are more likely to differ from any such guidance. In light of the foregoing, investors are urged to put the guidance in context and not to place undue reliance on it.

Declines in the semiconductor industry or worldwide economic conditions may cause demand for our products to decrease and may adversely affect our business.

Declines in industry or worldwide economic conditions may adversely affect our business. Our revenue is primarily dependent upon demand from semiconductor manufacturers, which is largely driven by the current and anticipated demand for electronic products that utilize semiconductors. Despite recent increases in demand for semiconductors in applications such as smartphones, 5G wireless technology, cloud computing, the Internet of Things, machine learning and artificial intelligence, autonomous vehicles and virtual reality, the semiconductor industry has historically been, and is likely to continue to be, cyclical with periodic significant downturns, resulting in significantly decreased demand for products such as ours. While demand for semiconductors has remained robust, the COVID-19 pandemic has significantly increased economic and demand uncertainty and contributed to substantial volatility in global markets, including those in which we participate. We anticipate that the pandemic will continue to contribute to the global economic slowdown, and it is possible that it could cause a global recession, each of which may adversely affect our business. We have previously experienced significant revenue deterioration and operating losses due to severe downturns in the semiconductor industry, which often occur suddenly. The semiconductor industry is also affected by seasonal shifts in demand. We are unable to predict the timing, duration or severity of any future downturns in the semiconductor industry. As a result, we could underperform the market or our peers.

During downturns and periods of soft demand, our revenue is reduced and we typically experience greater pricing pressure and shifts in product and customer mix, which often adversely affect our gross margin and net income. Furthermore, to remain competitive, we must maintain a satisfactory level of engineering, research and development activity, invest in our infrastructure and maintain the ability to respond to any increases in demand and, as a result, a lower volume of sales can have a large and disproportionate impact on our profitability. Even moderate seasonality can cause our operating results to fluctuate significantly from one period to the next. Uncertain and volatile economic, political, public health or business conditions in any of our key sales regions can cause or exacerbate negative trends in business and consumer spending and have historically impacted customer demand for our products. These conditions can cause material adverse changes in our results of operations and financial condition, including:

•a decline in demand for our products, which, given our limited backlog, will have an immediate impact on our revenues;

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

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

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

•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;

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

15

•additional cost reduction efforts, including additional restructuring activities, which may adversely affect our ability to capitalize on opportunities.

We anticipate that the COVID-19 pandemic, including potential additional waves of infection, may cause us to experience at least some of these adverse changes, but we cannot predict the timing or degree to which they will occur, if at all.

The industries we serve are constantly evolving, and any failure to manage our business effectively during periods of rapid change may adversely affect our business performance and results of operations.

Intense competition in the semiconductor industry often leads to rapid changes in products and technology, and those changes can significantly alter demand for our products. Changes in demand may arise from factors such as advances in fabrication processes, new and emerging technologies, end-user demand, customers’ production capacity and customers’ capacity utilization. The amount and mix of spending on different products and solutions can significantly impact our results of operations.

We regularly reassess our allocation of resources in response to the changing business environment. To meet rapidly changing demand, we must accurately forecast demand for each of our products and effectively manage our resources and production capacity across our various businesses, and we may incur unexpected or additional costs to align our operations with demand. If we do not adequately adapt to changes in our business environment, we may lack the infrastructure and resources to scale up our business to meet customer expectations and compete successfully during a period of growth, or we may expand our capacity too rapidly, resulting in excess fixed costs. Even with effective allocation of resources and management of costs, during periods of decreasing demand, our gross margins and earnings will usually be adversely impacted. Especially during transitional periods, resource allocation decisions can have a significant impact on our future performance, particularly if we have not accurately anticipated the correct mix of industry changes. Our success will depend, to a significant extent, on our management’s ability to identify and respond to these challenges effectively.

Our ability to increase sales of our products, particularly our capital equipment 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 expand our manufacturing capacity on a timely basis, manage the expansion effectively and obtain larger quantities of raw materials, our customers could obtain such products from our competitors, which would reduce our market share. Additionally, we typically operate our business on a just-in-time shipment basis with a modest level of inventory, ordering supplies and planning production based on internal demand forecasts. The failure to accurately forecast demand for our products, in terms of both volume and product type, has in the past led to, and may in the future lead to, delays in product shipments and disappointment of customer expectations, as well as an increased risk of excess and obsolete inventory.

Our revenues and operating results are variable.

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. We manage our expenses based in part on our expectations of future revenues. Because some of our expenses are relatively fixed in the short term, a change in the timing of revenue or the amount of profit we generate from a small number of transactions can unfavorably affect operating results in a particular period. Factors that may cause our financial results to fluctuate unpredictably include:

•economic conditions in the semiconductor industry or in the other industries we serve;

•the impact of the COVID-19 pandemic on the global economy, the semiconductor industry, the other industries we serve, our manufacturing capabilities or our supply chain;

•the size and timing of customer orders;

•consolidation of our customers, which could impact their purchasing decisions and negatively affect our revenues;

•procurement shortages;

•the failure of our suppliers or outsource providers to perform their obligations;

•manufacturing difficulties;

•additional expenses we would expect to incur in our efforts to respond promptly to any supply shortages, manufacturing difficulties or other supplier problems;

•decisions to increase or accelerate our purchasing of raw materials, components or other supplies in an effort to mitigate supply risk;

•customer decisions to decelerate orders in order to draw down their inventory;

16

•customer cancellations of or delays in shipments, installations or customer acceptances or, alternatively, acceleration of orders from customers to increase their inventory;

•our customers’ rate of replacement of our consumable products;

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

•our ability to develop, introduce and market new, enhanced and competitive products in a timely manner;

•our competitors’ introduction of new products;

•legal or technical challenges to our products or technologies;

•disruptions in transportation, communication, demand, information technology or supply, including strikes, acts of God, wars, terrorist activities and natural or man-made disasters;

•legal, tax, accounting or regulatory changes (including changes in import/export regulations and tariffs) or changes in the interpretation or enforcement of existing requirements;

•changes in our estimated tax rate; and

•foreign currency exchange rate fluctuations.

The COVID-19 pandemic is likely to exacerbate the adverse impact of many of these factors on our revenues and results of operations, at least in the short term.

We depend on single and limited source suppliers, and an interruption in our ordinary sources of supply could affect our ability to manufacture our products and have an adverse effect on our results of operations.

We rely on single or limited source suppliers for certain raw materials that are critical to the manufacturing of our products, such as plastic polymers, filtration membranes, petroleum coke and other materials. If we were to lose any one of these sources, it could be difficult for us to find an alternative supplier and we would need to qualify this new source through our customers’ rigorous qualification processes. Although we seek to reduce our dependence on single and limited source suppliers, the partial or complete loss of any of these sources could interrupt our manufacturing operations and result in a material adverse effect on our results of operations.

At times, we have experienced a limited supply of certain raw materials, which has resulted in delays, lost revenue, increased costs and risks associated with qualifying products that are manufactured using such new raw materials with our customers. Events such as an industry-wide increase in demand for, or the discontinuation of, raw materials used in our products could harm our ability to acquire sufficient quantities of such raw materials, and our manufacturing operations may be interrupted. For example, in 2019 we experienced a disruption in the supply of certain ceramic material for use in our coatings business in our SCEM division when the supplier was unable to produce these materials at the required specifications. In response, we worked collaboratively with the supplier to determine the root cause and to solve the manufacturing issue, reestablishing the supply of these materials. Although we were able to timely reestablish our supply of this raw material, we may be unable to do so in the future or with other raw materials, in which case raw materials shortages may adversely affect our operations. Additionally, our suppliers may not have the capacity to meet increases in our demand for raw materials, in turn, making it difficult for us to meet demand from our customers. Furthermore, prices for our raw materials can vary widely. While we have long-term arrangements with certain key suppliers that fix our price for the purchase of certain raw materials, if the cost of our raw materials increases and we are unable to correspondingly increase the sales price of our products or find other cost savings, our profit margins will decline.

Although we have not yet experienced any significant impacts or interruptions to our supply chain as a result of the COVID-19 pandemic, there is no assurance that they will not occur in the future. Certain of our suppliers have faced difficulties maintaining operations in light of government-ordered restrictions, shelter-in-place mandates and outbreaks of infection within their workforces. As the pandemic continues, our suppliers may face challenges in maintaining their level of supply as a result of these or other factors. If our suppliers or sub-suppliers are unable to maintain their operations or restrictions become more severe, we may encounter difficulties obtaining raw materials, which may cause us to fail to meet customer demand or require us to pay higher prices for these materials, either of which could harm our business and profitability. For example, as a result of the COVID-19 pandemic, one of our critical valve suppliers was shut down and was unable to supply us with valves for our gas purification products. Although in this instance we were able to procure this critical part from a second, pre-qualified source, we may be unable to find alternative sources of supply for this or other products in the future and may therefore be adversely affected by supply interruptions resulting from the COVID-19 pandemic. To mitigate the risk of potential supply interruptions from the COVID-19 pandemic, during 2020 and into 2021, we chose to increase certain inventory levels, causing us to hold more inventory than we might have otherwise maintained. Additionally, an economic slowdown caused by the COVID-19 pandemic or otherwise could harm the financial health of our suppliers and sub-suppliers. Although we regularly monitor the

17

financial health of companies in our supply chain, financial hardship on our suppliers or sub-suppliers could cause a disruption in our ability to obtain raw materials or components or adversely affect our operations. Further, we may have to increase our safety stocks of raw materials or components or alter our payment terms with certain suppliers, including prepaying for raw materials, any of which could put downward pressure on our cash flow.

We are exposed to the risks of operating a global business as a significant amount of our sales and manufacturing activity occur outside the United States.

Sales to customers outside the United States accounted for approximately 75%, 76% and 78% of our net sales in 2020, 2019 and 2018, 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 manufacture a significant portion of our products outside the United States and are dependent on international suppliers for many of our parts and raw materials. We intend to continue to pursue opportunities in both sales and manufacturing internationally. Our international operations are subject to a number of risks and potential costs that could adversely affect our revenue and profitability, including:

•border closures, travel bans, entry limitations or inspections and other restrictions on the international movement of goods, including actions to limit the export of goods in order to secure a domestic supply in light of actual or anticipated global shortages, as well as the potential exercise of governmental power to requisition or prioritize the production of specified goods or to commandeer facilities in the public interest, such as in the effort to combat the COVID-19 pandemic, any of which could adversely affect our ability to obtain supplies and deliver our products to customers;

•the implementation of laws, rules, regulations, policies and other government actions, such as “trade wars,” tariffs, sanctions or other changes in international trade requirements that affect our business and that of our customers and suppliers, any of which could impose additional costs on our operations and limit our ability to operate our business;

•challenges in hiring and integrating workers in different countries;

•challenges 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;

•challenges of maintaining appropriate business processes, procedures and internal controls and complying with legal, environmental, health and safety, anti-bribery, anti-corruption and other regulatory requirements that vary by jurisdiction, including new and evolving requirements for social distancing and other measures to minimize the spread of COVID-19;

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

•fluctuating pricing and availability of raw materials and supply chain interruptions or slowdowns, including as a result of difficulties, financial or otherwise, faced by segments of the transportation industry;

•public health crises, such as the COVID-19 pandemic;

•expense and complexity of complying with U.S. and foreign import and export regulations, including the ability to obtain required import and export licenses;

•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, including the Japanese yen, euro, Taiwanese dollar, Korean won, Chinese renminbi, Singapore dollar, Malaysian ringgit, Canadian dollar or Israeli shekel, which could cause our sales and profitability to decline;

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

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

•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

•political and economic instability and uncertainty, which may result in severely diminished liquidity and credit availability, rating downgrades of sovereign debt, declining valuation of certain investments, declines in consumer confidence, declines in economic growth, volatility in unemployment rates and uncertainty about economic stability.

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.

18

Tariffs, export controls and other trade laws and restrictions resulting from international trade disputes, strained international relations and changes to foreign and national security policy, especially as they relate to China, could have an adverse impact on our operations.

Tariffs, additional taxes, trade barriers and other measures, particularly those arising out of relations between the United States and China, may increase costs of raw materials and our manufacturing costs, decrease margins, reduce the competitiveness of our products or inhibit our ability to sell products or purchase necessary equipment and supplies, any of which could have a material adverse effect on our business, results of operations or financial condition. For example, both the United States and China have implemented several rounds of tariffs and retaliations with respect to certain products imported from the other country, some of which have impacted certain raw materials we use. We have made operational changes in an effort to mitigate the impact of these tariffs on our products, but our efforts may not be successful.

In addition, 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 end users, countries and nationals of certain countries. In certain circumstances, these restrictions may prohibit the transfer of certain of our products, services and technologies, and in other circumstances they may require us to obtain a license from the U.S. government before delivering the controlled item or service. 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 be ineffective or circumvented, exposing us to legal liabilities. Compliance with these laws could significantly limit our sales in the future. Changes in, and responses to, U.S. trade controls could reduce the competitiveness of our products and cause our sales to drop, which could have a material adverse effect on our business, financial condition and results of operations.

In addition to the tariffs mentioned above, over the last several years and accelerating during 2020, the U.S. government has significantly expanded export controls on certain technologies and commodities to certain markets, particularly with respect to semiconductor and other high technology exports to China. For example, effective June 29, 2020, the U.S. Department of Commerce imposed new export controls on the transfer of many U.S. products and technologies, including many commercial-grade electronics, to “military end users” in China, a term which may include many Chinese commercial companies that sell products to or do business with the military. Likewise, beginning in May 2019, the U.S. Department of Commerce imposed significant restrictions on the transfer of any products from the United States, as well as many products produced overseas that incorporate U.S. content or rely on U.S. software or technology, to Huawei Technologies Co., Ltd. and several of its overseas affiliates, including HiSilicon, and took similar action against Semiconductor Manufacturing International Corporation in December 2020. The U.S. government also continuously assesses which “emerging and foundational technologies” warrant new or additional controls, which could subject additional U.S.-origin products and services to more stringent export restrictions. It is possible that these modified regulations, and any future regulations, could reduce demand for our products. These restrictive measures may reduce overall global demand for our customers’ products or for other products produced or manufactured in the United States or based on U.S. technology, in turn reducing demand for our products, which could have a material adverse effect on our business, financial condition and results of operations. Such risks may be especially exacerbated as they relate to China, a market that is important to our business, representing approximately 13% of our sales in each of the last three years.

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. Our top ten customers accounted for 46%, 43% and 44% of our net sales in 2020, 2019 and 2018, respectively. Our customers could stop using our products in their manufacturing processes with limited advance notice to us, and we would have limited or no contractual recourse. 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 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.

Furthermore, the semiconductor industry has been undergoing, and is expected to continue to undergo, consolidation. If any of our customers merge or are acquired, we may experience lower overall sales from the merged or combined companies. In addition, our principal customers also hold considerable purchasing power and may be able to negotiate sales terms that result in decreased pricing, increased costs, and/or lower margins for us, and limitations on our ability to share jointly developed technology with others.

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, our business could be seriously harmed.

19

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. For this reason, we make significant expenditures to research, develop, engineer and market new products and make significant capital investments in technology and manufacturing capacity in anticipation of future business and without any purchase commitment from our customers. We incurred $136.1 million, $121.1 million and $118.5 million for engineering, research and development expense in 2020, 2019 and 2018, respectively, to support new product and technology development. 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, we may lose market share and our revenue and our profitability may decline. For example, in the past, we incurred significant impairment charges for capital expenditures related to developing the capability to manufacture shippers and FOUPs for 450 mm wafers, which major semiconductor manufacturers announced that they would not initiate manufacturing in the foreseeable future.

We believe that our future success will depend upon our ability to continue to develop 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 and significantly reduce our sales. For example, as 3D NAND technology advances to higher densities, the conventional process used to etch critical features no longer works. Recognizing the need for a new chemistry, we developed a series of prototype formulations for highly selective nitride etch and developed a specialized liquid filter that removes contaminants while simultaneously maintaining the critical components that make the chemistry function. While we believe we are well positioned for selection as the process-of-record for these specific etch processes and we are preparing for rapid, high-volume ramp once the final selection is made, we may not be selected by the customer and may not generate significant revenue from these solutions. We cannot assure you that the new products and technology we choose to develop and market will be successful. In addition, if new products have reliability or quality problems, we may experience reduced orders, higher manufacturing costs, delays in acceptance and payment, additional service and warranty expense and damage to our reputation.

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

We operate in a highly competitive industry. We face many 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, regional companies, which 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.

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

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

•experiencing 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;

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

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

•entering into markets in which we have limited or no prior experience;

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

•inability to complete proposed transactions due to the failure to obtain regulatory or other approvals;

20

•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;

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

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

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

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

•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;

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

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

•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;

•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;

•we could experience 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;

•an acquired company may have inadequate or ineffective internal control over financial reporting, disclosure controls and procedures, cybersecurity, privacy, environmental, health and safety, anti-bribery, anti-corruption, human resource or other policies or practices, which may require unexpected or additional integration, mitigation and remediation costs;

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

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

For example, an inability to realize the full extent of, or any of, the anticipated benefits of the Sinmat and Global Measurement Technologies Inc., or GMTI, acquisitions we completed in 2020, as well as any delays encountered in the integration processes, could have an adverse effect on our business and results of operations, which may adversely affect the value of the shares of our common stock.

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

Our manufacturing processes are complex and require the use of expensive and technologically sophisticated equipment and materials. These processes are frequently modified to improve manufacturing yields, process stability and product quality. We have, on occasion, experienced manufacturing difficulties, such as critical equipment breakdowns or the introduction of impurities in the manufacturing process. Any future difficulties could cause lower yields, make our products unmarketable and/or delay deliveries to customers. In addition, any modification to the manufacturing process of a product could require that the product be re-qualified by customers, which can increase our costs and delay our ability to sell this product to our customers. These and other manufacturing difficulties may result in the loss of sales and exposure to warranty and product liability claims.

Some of our products are manufactured at only one or two facilities in different countries, many of which are subject to severe weather and natural catastrophes, such as typhoons in Taiwan, Malaysia and China, earthquakes in Japan and Taiwan, hurricanes in east Texas and Florida, wildfires in California and Colorado and flooding in Arkansas. Our suppliers and customers face similar dangers. Although we have continuity plans designed to mitigate the impact of natural disasters on our operations, those plans may be insufficient, and any catastrophe may disrupt our ability to manufacture and deliver products to our customers, resulting in an adverse impact on our business and results of operations. A disruption at our manufacturing facilities could impact sales of the products manufactured at those facilities until another facility could commence or expand production of those products, and disruptions at our other facilities may similarly adversely affect our operations. In addition to natural disasters, disruptions may be caused by a other factors, including civil unrest, outbreaks of disease, terrorist actions or other events outside our control. For example, in response to the COVID-19 pandemic, in 2020 the government of Malaysia issued an order that significantly reduced the number of employees who could be physically present to operate our Malaysian facility, which temporarily reduced the productivity of that plant. We have moved, and we may again move, the manufacture of

21

certain products from one plant to another. 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 level of cost savings or efficiencies that we anticipated, if any.

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 liability for personal injury, death, damage to property and contamination of the environment; suspension of operations; the imposition of civil or criminal fines, penalties and other sanctions; cleanup costs; claims by governmental entities or third parties; reputational harm; increases in our insurance costs; and 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, potentially creating significant product liability exposure for us. Our insurance may be inadequate to satisfy any such liabilities, and our financial results or financial condition could be adversely affected.

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 the services of any of our key employees or an inability to attract, train and retain qualified and skilled employees, particularly research and development and engineering personnel, could 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. As a result, the difficulty and costs associated with attracting and retaining key 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 to protect many of our major product platforms. Although we often file applications for additional patents, our pending applications may not be approved. Moreover, any patents that we own or obtain may not provide us with any competitive advantage, and these patents may expire or be challenged, invalidated, circumvented, rendered unenforceable or otherwise compromised by third parties. We may not develop additional proprietary technology. In addition, any failure to obtain intellectual property protection in the international jurisdictions we serve could expose us to increased competition, which could limit our growth and future revenue. Although we enter into confidentiality agreements with our employees and certain third parties to protect our proprietary information and technology, these agreements may be inadequate to protect our interests, and the remedies available to us for any breach may not adequately mitigate any breach. Furthermore, third parties may be able to replicate or obtain our confidential and proprietary information and technology through lawful means, and they may also be able to design around our patents. Additionally, we may lose trade secret protection as a result of the actions or omissions of us, our employees or third parties. Any weakness in our ability to protect our intellectual property could adversely affect our business, financial condition and results of operations.

Third parties may misappropriate our intellectual property rights, and disputes regarding intellectual property rights may arise. We may bring litigation in order to enforce our patents, copyrights or other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources and could negatively affect our sales, profitability and prospects regardless of whether our efforts are successful. For example, from 2015 until 2020, we were party to litigation to enforce our rights against Gudeng Precision Inc., Ltd. for their patent infringement. We settled this dispute in 2020 by licensing certain of our intellectual property rights to Gudeng. We continue to vigorously defend our patents and rights, which will cause us to incur costs. We may initiate other costly litigation against our competitors or other third parties in order to protect our intellectual property rights. We cannot predict how any existing or future litigation will be resolved or what impact it may have on us.

Our commercial success also depends, in part, on our ability to avoid infringing or misappropriating any patents or other proprietary rights of third parties. If we infringe or misappropriate a third party’s patent or other proprietary rights, we could be required to pay damages, alter our products or processes, obtain a license to continue use of a proprietary right or cease utilizing

22

such proprietary rights, including making or selling products utilizing such proprietary rights. If we are required to obtain a license, we may be unable to do so on commercially acceptable terms, or at all.

We may be subject to information technology system failures, network disruptions and breaches in data security, which could damage our reputation and adversely affect our financial condition, results of operations and cash flows, and new laws and regulations regarding data privacy may increase our costs.

We 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 information technology, or 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 disruption, breach or failure. Data breaches, including those sponsored by state actors, have become increasingly common in recent years. For example, during 2020 the United States government was hacked via third-party software applications by hackers suspected of being sponsored by a foreign intelligence agency. While we and our third-party providers have implemented network security procedures, virus protection software, intrusion prevention systems, access control, emergency recovery processes and internal control measures, we and they have experienced, and expect to continue to be subject to, cybersecurity threats and incidents ranging from employee error or misuse, to individual attempts to gain unauthorized access to systems, to sophisticated and targeted measures known as advanced persistent threats. Despite the precautions undertaken by us and our third-party providers, IT system failures, network disruptions and breaches of data security could cause disruption in our operations, issues with customer communication and order management, the unauthorized or unintentional disclosure of sensitive information, disruptions in our transaction processing or 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. These risks may be further amplified by the increased reliance on remote access to IT systems by us and our customers, suppliers and other third parties with which we do business as a result of employees working remotely in response to the COVID-19 pandemic.

Moreover, new laws and regulations, such as the European Union’s General Data Protection Regulation and the California Consumer Privacy Act, add to the complexity of our compliance obligations, which increases our compliance costs. Although we have established internal controls and procedures intended to achieve compliance with such laws and regulations, a failure to fully comply could result in significant penalties.

Risks Related to Government Regulation

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

Failure to comply with the wide variety of federal, state, local and non-U.S. regulatory requirements relating to the release, use, storage, treatment, transportation, discharge, disposal and remediation of, and human exposure to, hazardous chemicals could result in future liabilities or the suspension of production or shipment. These requirements have tended to become stricter over time. For example, the Frank R. Lautenberg Chemical Safety for the 21st Century Act modified the Toxic Control Substances Act, or TSCA, by requiring the Environmental Protection Agency, or the EPA, to prioritize and evaluate the environmental and health risks of existing chemicals and provided the EPA with greater authority to regulate chemicals posing unreasonable risks. According to this statute, the EPA is required to make an affirmative finding that a new chemical will not pose an unreasonable risk before such chemical can go into production. As a result, TSCA now operates in a similar fashion to the Registration, Evaluation, and Authorization of Chemicals, or REACH, legislation in Europe. Regulations similar to REACH have also been enacted in South Korea and Taiwan. These laws and regulations, among others, increase the complexity and costs of transporting our products from the country in which they are manufactured to our customers. Further changes to these and similar regulations could restrict our ability to expand, build or acquire new facilities, require us to acquire costly control equipment, cause us to incur expenses associated with remediation of contamination, cause us to modify our manufacturing or shipping processes or otherwise increase our cost of doing business and have a negative impact on our financial condition, results of operations and cash flows. In addition, the adoption of new laws, rules or regulations related to climate change poses risks that could harm our results of operations or affect the way we conduct our businesses. For example, new or modified regulations could require us to make substantial expenditures to enhance our environmental compliance efforts.

We are exposed to various risks from our regulatory environment.

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

23

governing bodies, including those related to health and safety, export controls, financial and other disclosures, corporate governance, 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, and may present risks to our business, including potential fines, restrictions on our actions and reputational damage if we do not fully comply. The volume of changes to such laws, rules and regulations may be especially significant in the United States over the next several quarters as the Biden administration implements its policies.

To maintain high standards of corporate governance and public disclosure, we intend to invest appropriate resources to comply with evolving standards. Changes in or ambiguous interpretations of laws, regulations and standards may create uncertainty regarding compliance matters. Efforts to comply with new and changing regulations have resulted in, and are likely to continue to result in, increased administrative expenses and a 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 United States. 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 a number of 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 other jurisdictions, including members of the Organization for Economic Cooperation and Development, are considering changes to their tax laws, including provisions intended to address base erosion and profit shifting by taxpayers. Any tax reform adopted in these or other countries may exacerbate the risks described above.

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, 2020, we had an aggregate principal amount of $1,095.0 million of indebtedness outstanding, including our 4.625% senior unsecured notes due April 1, 2026 and our 4.375% senior unsecured notes due April 15, 2028, or collectively the Notes, and our senior secured term loan facility due 2025, or the Term Loan Facility. In addition, we have approximately $300 million of unutilized capacity under our senior secured revolving credit facility due 2023, or the Revolving Facility. We refer to the Term Loan Facility and the Revolving Facility as the Credit Facilities, and the credit agreement that governs the Credit Facilities as the Credit Agreement.

Further, we may incur significant additional secured and unsecured indebtedness in the future. Although the indentures governing the Notes, or the Indentures, and the Credit Agreement restrict our ability to incur additional indebtedness, the restrictions have a number of significant qualifications and exceptions. For example, the Credit Agreement provides that we can request additional loans and commitments up to the greater of $400 million 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:

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

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

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

24

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

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

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 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.

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 Credit Agreement may restrict our operations, particularly our ability to respond to changes or raise additional funds.

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

•incur additional indebtedness and guarantee indebtedness;

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

•prepay, redeem or repurchase certain debt;

•make investments, loans, advances and acquisitions;

•sell or otherwise dispose of assets, including capital stock of our subsidiaries;

•enter into transactions with affiliates;

•alter the businesses we conduct; and

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

In addition, the restrictive covenants 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. 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. 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 2020, the closing price of our stock on The Nasdaq Global Select Market, or Nasdaq, ranged from a low of $39.03 to a high of $99.03, 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:

•the significant increase in volatility in the stock market in general as a result of the COVID-19 pandemic;

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

25

•changes in global economic conditions, including those resulting from trade tensions or the COVID-19 pandemic;

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

•changes in financial estimates by securities analysts;

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

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

•the public perception of equity values of publicly traded companies;

•fluctuations in our results of operations; and

•the 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. We believe that period-to-period comparisons of our results of operations may not be meaningful, and you should not rely upon them as indicators of our future performance. Future decreases in our stock price may adversely impact our ability to raise sufficient additional capital in the future, if needed.

There can be no assurance that we will continue to declare cash dividends or repurchase our shares in any particular amounts or at all.

Future payments of quarterly dividends and 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 share repurchases may be affected by, among other factors, potential capital requirements in 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. Our dividend payments and share repurchases may change from time to time, and we may decide at any time to reduce, suspend or discontinue the payment of dividends or the repurchase of shares. A reduction, suspension or discontinuation of our dividend payments or share repurchases could have a negative effect on the price of our common stock.

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.

Overview

This overview is not a complete discussion of the Company’s financial condition, changes in financial condition and results of operations; it is intended merely to facilitate an understanding of the most salient aspects of its financial condition and operating performance and to provide a context for the detailed discussion and analysis that follows, and must be read in its entirety in order to fully understand the Company’s financial condition and results of operations.

The Company is a leading supplier of advanced materials and process solutions for the semiconductor and other high-technology industries. Our mission is to help our customers improve their productivity, performance and technology by providing solutions for the most advanced manufacturing environments. We leverage our unique breadth of capabilities to create mission-critical microcontamination control products, specialty chemicals and advanced materials handling solutions that maximize manufacturing yields, reduce manufacturing costs and enable higher device performance for our customers.

Our customized materials solutions enable the highest levels of performance essential to the manufacture of semiconductors. As our customers introduce more complex architectures and search for new materials with better electrical and structural properties to improve the performance of their devices, they rely on Entegris as a trusted partner to address these challenges. We understand these challenges and have solutions to address them, such as our advanced deposition materials, implant gases, formulated cleaning chemistries and selective etch chemistries. Our customers also require greater end-to-end materials purity and integrity in their manufacturing process that, when combined with smaller dimensions and more complex architectures, can be challenging to achieve. To enable the use of new metals and the further miniaturization of chips, and to maximize yield and increase long-term device reliability, we provide products such as our advanced liquid and gas filtration and purification products that help to selectively remove new classes of contaminants throughout the semiconductor supply chain. In addition, to ensure purity levels are maintained across the entire supply chain, from bulk manufacturing, to transportation to and delivery through a fab, to application onto the wafer, we provide high-purity packaging and materials handling products.

Our business is organized and operated in three operating segments, which align with the key elements of the advanced semiconductor manufacturing ecosystem. The Specialty Chemicals and Engineered Materials, or SCEM, segment provides

34

high-performance and high-purity process chemistries, gases, and materials, and safe and efficient delivery systems to support semiconductor and other advanced manufacturing processes. The Microcontamination Control, or MC, segment offers solutions to filter and purify critical liquid chemistries and gases used in semiconductor manufacturing processes and other high-technology industries. The Advanced Materials Handling, or AMH, segment develops solutions to monitor, protect, transport, and deliver critical liquid chemistries, wafers and other substrates for a broad set of applications in the semiconductor industry, life sciences and other high-technology industries. While these segments have separate products and technical know-how, they share common business systems and processes, technology centers, and strategic and technology roadmaps. With the technology, capabilities and complementary product portfolios from these three segments, we are uniquely positioned to collaborate across divisions to create new, co-optimized and increasingly integrated solutions for our customers. For example, our SCEM segment offers a highly selective nitride etch chemistry, our MC segment provides a liquid filter that is specifically matched to that formulation and our AMH segment ensures the integrity of the product as it is moved to and through the fab environment.

Key operating factors Key factors which management believes have the largest impact on the overall results of operations of the Company include:

•Level of sales Since a significant portion of the Company’s product costs (except for raw materials, purchased components and direct labor) are largely fixed in the short-to-medium term, an increase or decrease in sales affects gross profits and overall profitability significantly. Also, increases or decreases in sales and operating profitability affect certain costs such as incentive compensation and commissions, which are highly variable in nature. The Company’s sales are subject to the effects of industry cyclicality, technological change, substantial competition, pricing pressures and foreign currency fluctuation.

•Variable margin on sales The Company’s variable margin on sales is determined by selling prices and the costs of manufacturing and raw materials. This is affected by a number of factors, which include the Company’s sales mix, purchase prices of raw material (especially polymers, membranes, stainless steel and purchased components), domestic and international competition, direct labor costs, and the efficiency of the Company’s production operations, among others.

•Fixed cost structure The Company’s operations include a number of large fixed or semi-fixed cost components, which include salaries, indirect labor and benefits, facility costs, lease expenses, and depreciation and amortization. It is not possible to vary these costs easily in the short term as volumes fluctuate. Accordingly, increases or decreases in sales volume can have a large effect on the usage and productivity of these cost components, resulting in a large impact on the Company’s profitability.

Impact of COVID-19 on our Business

As a result of the COVID-19 pandemic, governmental authorities have implemented and are continuing to implement numerous and constantly evolving measures to try to contain the virus, such as travel bans and restrictions, masking recommendations and mandates, limits on gatherings, quarantines, shelter-in-place orders and business shutdowns. In some cases, governmental re-opening plans have been delayed or reversed due to spikes in the number of infections in the local area. We continue to monitor the situation regarding the COVID-19 pandemic, which remains fluid and uncertain, and to proactively manage and adapt our responses in collaboration with our employees, customers and suppliers. However, we are unable to accurately predict the full impact that COVID-19 may have on our business, results of operations, financial condition, liquidity and cash flows, which will depend on future developments that are highly uncertain and cannot be predicted with accuracy, including, but not limited to, the duration and continued spread of the outbreak, its severity, potential additional waves of infection, the actions to mitigate the virus or its impact, the development, distribution, efficacy and acceptance of vaccines and how quickly and to what extent normal economic and operating conditions can resume.

Health and Safety

Commencing in the first quarter of 2020, we have taken, and continue to take, proactive, aggressive action to protect the health and safety of our employees, customers, partners and suppliers. We enacted rigorous safety measures, including social distancing protocols, encouraging employees who do not need to be physically present on the manufacturing floor or in a lab to perform their work to work from home, suspending non-essential travel, implementing temperature checks and other access controls at the entrances to our facilities, extensively and frequently disinfecting our workspaces and providing masks to employees who are physically present at our facilities. We expect to continue to implement these measures until the COVID-19 pandemic is adequately contained, and we may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees, customers, partners and suppliers. We expect that the pandemic may abate at different times in different regions, and accordingly our health and safety protocols may vary across regions.

Operations

35

We have important manufacturing operations in the United States, Japan, Korea, China, Malaysia, and Taiwan, all of which have been affected by the outbreak and have taken measures to try to contain it. Measures providing for business shutdowns have generally excluded certain essential services, and those essential services have commonly included critical infrastructure and the businesses that support that critical infrastructure. While all of our facilities currently remain operational, these measures have impacted and may further impact our workforce and operations, as well as those of our customers, suppliers and other third parties with which we do business. For example, in March 2020 the government of Malaysia issued an order that significantly reduced the number of employees who could be physically present to operate our Malaysian plant, which temporarily reduced the productivity of that plant. The government of Malaysia issued a similar order restricting movement throughout that country in January 2021, which has not impacted our operations as of the date of this filing but may do so in the future. Our Malaysian plant is operating at full capacity as of the date of this filing. In addition to reduced productivity, constraints and limits imposed on our operations may slow or diminish our research and development and customer qualification activities. During 2020, we experienced brief interruptions in operations at our sites in Hangzhou, China, San Luis Obispo, California and Bedford, Massachusetts and so far during 2021 we have experienced minor interruptions in operations at our site in San Luis Obispo, California and a brief construction delay to an expansion of our facility in Toronto, Canada. While governmental measures may be modified, extended or reimposed, we expect that, absent a significant surge in infections in the relevant local area or within our workforce or those of our suppliers, our manufacturing and research and development facilities will remain operational, largely at or near full capacity. In connection with the COVID-19 pandemic, we have experienced limited absenteeism from employees who are required to be on-site to perform their jobs. We do not currently expect that our operations will be materially adversely affected by significant absenteeism. In addition, we have incurred incremental employee compensation related to the COVID-19 pandemic. For example, since April 2020, we have awarded certain of our employees who are required to physically report to a manufacturing facility in order to perform their jobs during the COVID-19 crisis with a special appreciation bonus for their efforts in sustaining our production continuity.

Supply

We have not yet experienced any significant impacts or interruptions to our supply chain as a result of the COVID-19 pandemic. However, certain of our suppliers have faced difficulties maintaining operations in light of government-ordered restrictions, shelter-in-place mandates and outbreaks of infection within their workforces. As the pandemic continues, our suppliers may face challenges in maintaining their level of supply as a result of these or other factors. For example, as a result of the COVID-19 pandemic, during the first half of 2020, one of our critical valve suppliers was shut down and was unable to supply us with valves for certain of our gas purification products. In this instance we were able to procure this critical part from a second, pre-qualified source. Although we regularly monitor the financial health of companies in our supply chain, financial hardship on our suppliers or sub-suppliers caused by the COVID-19 pandemic could cause a disruption in our ability to obtain raw materials or components required to manufacture our products and thus require us to increase our safety stocks of certain raw materials or components, adversely affecting our operations. To mitigate the risk of potential supply interruptions from the COVID-19 pandemic, during 2020 and into 2021, we chose to increase certain inventory levels, causing us to hold more inventory than we might have otherwise maintained. We may decide to take similar actions going forward, which may result in increased charges for excess or obsolete inventory, which would have the effect of reducing our profitability. Additionally, restrictions or disruptions of transportation, such as reduced availability of air transport, port closures and increased border controls or closures, have resulted, in certain instances, in higher costs and delays, both on obtaining materials and shipping finished goods to customers. If these restrictions and disruptions continue, they could harm our profitability, make our products less competitive or cause our customers to seek alternative suppliers.

Demand

The COVID-19 pandemic has significantly increased economic and demand uncertainty. During 2020, we saw strong demand from leading-edge customers associated with end-uses in servers and other data center applications. We believe that a portion of the orders that we received in 2020 may have been a result of customers increasing their inventory to reduce their exposure to risks of future supply disruptions, which could offset demand for our products in the future. We anticipate that the pandemic will continue to contribute to the current global economic slowdown, and it is possible that it could cause a global recession. In the event of a recession, demand for our products would decline and our business would be adversely affected.

Liquidity

Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on our future results, we believe our business model, our current cash reserves and our balance sheet leave us well-positioned to manage our business through this crisis as we expect it to unfold. We have taken recent steps to strengthen our balance sheet. On April 30, 2020, we issued $400 million aggregate principal amount of 4.375% senior unsecured notes due April 15, 2028. We used a portion of the net proceeds of the offering to repay approximately $142 million of borrowings under our senior secured revolving facility due 2023, or the Revolving Facility, representing the entire aggregate principal amount outstanding thereunder. We also used a portion of the net proceeds of the offering to repay approximately $251 million of outstanding borrowings under our senior secured term loan facility, or the Term Loan Facility.

36

We have reviewed numerous potential scenarios in connection with the impact of COVID-19 on the global economy and the semiconductor industry. Based on our analysis, we believe our existing balances of domestic cash and cash equivalents, which totaled $268.1 million as of December 31, 2020, 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.

We continue to monitor the rapidly evolving situation and guidance from international and domestic authorities, including federal, state and local public health authorities, and may take additional actions based on their recommendations and requirements or as we otherwise see fit to protect the health and safety of our employees, customers, partners and suppliers. In these circumstances, there may be developments outside our control requiring us to adjust our operating plan. As such, given the dynamic nature of this situation, we cannot reasonably estimate the impacts that COVID-19 may have on our financial condition, results of operations or cash flows in the future. See Item 1A, “Risk Factors,” for additional information regarding risks associated with the COVID-19 pandemic, including under the caption “The COVID-19 pandemic and ensuing governmental responses could materially adversely affect our financial condition and results of operations.”

Overall Summary of Financial Results for the Year Ended December 31, 2020

Total net sales for 2020 were $1,859.3 million up $268.2 million, or 17%, from sales of $1,591.1 million for 2019.

Total net sales increased primarily as a result of an increase in overall demand for the Company’s products from semiconductor industry customers, particularly in the sale of liquid filtration, advanced deposition materials and other areas of increasing importance to our customers. Total net sales also reflected net sales associated with acquisitions of $43.1 million and favorable foreign currency translation effects of $8.0 million.

The Company’s gross profit increased by $138.1 million for 2020 to $849.7 million, up from $711.7 million for the year ended December 31, 2019. Accordingly, the Company reported a 45.7% gross margin rate compared to 44.7% in 2019. The increases in gross profit and gross margin reflect higher factory utilization associated with stronger sales levels and a favorable sales mix.

The Company’s selling, general and administrative, or SG&A, expenses decreased in 2020 by $19.7 million, mainly reflecting lower deal costs and costs of integration activities, partially offset by higher employee costs.

The Company’s engineering, research and development, or ER&D, expenses increased in 2020 by $14.9 million, mainly reflecting higher employee costs.

As a result of the aforementioned and other factors discussed below, net income for 2020 was $295.0 million, or $2.16 per diluted share, compared to net income of $254.9 million, or $1.87 per diluted share, in 2019.

On January 10, 2020, the Company acquired Sinmat, a chemical mechanical planarization slurry manufacturer. Sinmat reports into the Specialty Chemicals and Engineered Materials segment of the Company. The total purchase price of the acquisition was $75.6 million, net of cash acquired. The transaction is described in further detail in note 3 to the Company’s consolidated financial statements.

On July 10, 2020, the Company acquired Global Measurement Technologies Inc., an analytical instrument provider for critical processes in semiconductor production, and its manufacturing partner Clean Room Plastics, Inc. (together, GMTI), for a purchase price of $36.3 million in cash. GMTI will report into the Advanced Materials Handling segment of the Company. The transaction is described in further detail in note 3 to the Company’s consolidated financial statements.

During 2020, the Company’s operating activities provided cash flow of $446.7 million. Cash, cash equivalents and short-term investments were $580.9 million at December 31, 2020 compared with $351.9 million at December 31, 2019. The Company had long-term borrowings, including current maturities, of $1,085.8 million at December 31, 2020 compared with $936.5 million at December 31, 2019.

Critical Accounting Policies

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, or 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, income taxes and business combinations. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. If management made different judgments or utilized different estimates, this 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.

37

The critical accounting policies that are most significantly affected by estimates, assumptions and judgments used in the preparation of the Company’s consolidated financial statements are discussed below.

Business Acquisitions

The Company accounts for acquired businesses using the acquisition method of accounting which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. The judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact net income. Accordingly, for significant items the Company typically obtains assistance from a third-party valuation firm.

There are several methods that can be used to determine the fair value of assets acquired and liabilities assumed in a business combination. For intangible assets, the Company normally utilizes the “income method.” This method starts with a forecast of all of the expected future net cash flows attributable to the subject intangible asset. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. Depending on the asset valued, the key assumptions included one or more of the following: (1) future revenue growth rates, (2) future gross margin, (3) future selling, general and administrative expense, (4) royalty rates, and (5) discount rates.

Estimating the useful life of an intangible asset also requires judgment. For example, different types of intangible assets will have different useful lives, influenced by the nature of the asset, competitive environment, and rate of change in the industry. Certain assets may even be considered to have indefinite useful lives. All of these judgments and estimates can significantly impact the determination of the amortization period of the intangible asset, and thus net income.

Net sales For 2020, net sales were $1,859.3 million, up $268.2 million, or 17%, from sales for 2019. An analysis of the factors underlying the increase in net sales is presented in the following table:

(In thousands)
Net sales in 2019	$	1,591,066
Increase associated with volume, pricing and mix	217,106
Increase associated with acquired businesses	43,092
Increase associated with effect of foreign currency translation	8,049
Net sales in 2020	$	1,859,313

38

The Company’s net sales reflected an increase in overall demand for the Company’s products from semiconductor industry customers, particularly in the sale of liquid filtration, advanced deposition materials and other areas of increasing importance to our customers. Total net sales also reflected net sales associated with acquisitions of $43.1 million favorable foreign currency translation effects of $8.0 million, mainly due to the strengthening of the Japanese yen and Taiwanese dollar relative to the U.S. dollar.

Sales percentage on a geographic basis for 2020 and 2019 and the percentage increase (decrease) in sales for 2020 compared to sales for 2019 were as follows:

	Year ended
	December 31, 2020		December 31, 2019		Percentage increase (decrease) in sales
North America	25	%	24	%	22	%
Taiwan	20	%	19	%	20	%
South Korea	15	%	15	%	12	%
Japan	13	%	13	%	18	%
China	13	%	13	%	15	%
Europe	8	%	8	%	17	%
Southeast Asia	5	%	7	%	(1)	%

The increase in sales for North America and Taiwan was primarily driven by a general increase in demand for products in all three of the Company’s segments. The increase in sales from South Korea relates to higher sales of Advanced Materials Handling products of 10% and Specialty Chemicals and Engineered Materials products of 5%. The increase in sales from Japan relates to higher sales of Microcontamination Control products of 10% and Specialty Chemicals and Engineered Materials products of 8%. The increase in sales for China was primarily driven by a general increase in demand for products in all three of the Company’s segments and additional sales attributable to the acquisition of Anow in the third quarter of 2019. The increase in sales from Europe primarily relates to higher sales of Microcontamination Control products.

Demand drivers for the Company’s business primarily consist of semiconductor fab utilization and production (unit-driven) as well as capital spending for new or upgraded semiconductor fabrication equipment and facilities (capital-driven). The Company analyzes sales of its products by these two key drivers. Sales of unit-driven products represented 70% of total sales and sales of capital-driven products represented 30% of total sales in both 2020 and 2019.

Gross profit Gross profit for 2020 increased by $138.1 million to $849.7 million, an increase of 19% from $711.7 million for 2019. The gross margin rate for 2020 was 45.7% versus 44.7% for 2019. The increases in gross profit and gross margin reflect higher factory utilization associated with stronger sales levels and a favorable sales mix. The gross profit and gross margin figures include an incremental cost of sales charge of $0.6 million and $7.5 million, associated with the sale of inventory acquired in recent business acquisitions for 2020 and 2019, respectively.

Selling, general and administrative expenses

Selling, general and administrative 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 2020 decreased $19.7 million, or 7%, to $265.1 million from $284.8 million in 2019. SG&A expenses, as a percent of net sales, decreased to 14.3% from 17.9% a year earlier, reflecting primarily the decrease in deal and integration costs.

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

(In thousands)
Selling, general and administrative expenses in 2019	$	284,807
Deal costs	(23,588)
Integration costs	(5,412)
Employee costs	8,530
Donation costs	1,990
Other decreases, net	(1,199)
Selling, general and administrative expenses in 2020	$	265,128

39

Deal and transaction costs were $23.6 million lower in 2020 compared to the prior year, mainly due to the deal costs associated with the terminated Versum transaction.

Engineering, research and development expenses

Engineering, research and development expenses consist of expenses for the support of current product lines and the development of new products and manufacturing technologies. These expenses were $136.1 million in 2020 and $121.1 million in 2019. ER&D expenses as a percent of net sales decreased to 7.3% from 7.6% a year earlier, reflecting the increase in sales, partially offset by higher employee costs.

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

(In thousands)
Engineering, research and development expense in 2019	$	121,140
Employee costs	11,135
Project related costs	2,387
Depreciation	1,861
Other decreases, net	(466)
Engineering, research and development expense in 2020	$	136,057

The Company’s overall ER&D efforts will continue to focus on developing and improving its technology platforms for semiconductor and advanced processing applications and identifying and developing products for new applications, and the Company often works directly with its customers to address their particular needs. The Company expects ER&D costs to stay relatively stable as a percentage of net sales.

Amortization of intangible assets Amortization of intangible assets was $53.1 million in 2020 compared to $66.4 million for 2019. The decrease primarily reflects the elimination of amortization expense of $21.1 million for identifiable intangible assets acquired in acquisitions that became fully amortized in previous periods, partially offset by additional amortization expense of $8.2 million associated with recent acquisitions as discussed in note 3 to the consolidated financial statements.

Interest expense Interest expense was $48.6 million in 2020 and $47.0 million in 2019. Interest expense includes interest associated with debt outstanding and the amortization of debt issuance costs associated with such borrowings. The increase primarily reflects higher average debt levels in 2020, partially offset by the absence of a $1.6 million charge in 2019 related to the adjustment of the fair value of the fixed deferred payment owed to the sellers with respect to the Company’s acquisition of DSC, for which the Company entered into a settlement agreement in 2019 to accelerate a fixed deferred payment of $16.1 million. The Company adjusted the fair value of the fixed deferred payment from its fair value to the stated value resulting in the additional aforementioned charge.

Interest income Interest income was $0.8 million in 2020 and $4.7 million in 2019. The decrease reflects lower average interest rates.

Other income, net Other income, net, was $6.7 million in 2020 compared to other income, net, of $121.1 million in 2019.

In 2020, other income, net consisted mainly of foreign currency transaction gains of $9.8 million, partially offset by loss on debt extinguishment costs of $2.4 million associated with payments on the Term Loan Facility.

In 2019, other income, net consisted mainly of net proceeds received of $122.0 million resulting from the termination of the merger agreement with Versum (see note 9 to the Company’s consolidated financial statements).

Income tax expense The Company recorded income tax expense of $59.3 million in 2020 compared to income tax expense of $63.2 million in 2019. The Company’s effective tax rate was 16.7% in 2020 compared to an effective tax rate of 19.9% in 2019.

The decrease in the effective tax rate in 2020 from 2019 is primarily due to an increase in discrete benefits related to share-based compensation of $8.8 million and lower accrued withholding taxes on foreign earnings. Additionally, the benefit related to the federal R&D tax credit increased by $1.5 million. These decreases were partially offset by a valuation allowance on federal foreign tax credit carryforwards of $6.2 million. The 2019 tax rate included a discrete tax charge of $9.4 million related to the reversal of the dividend received deduction benefit recorded in 2018. This discrete charge was recorded based on the issuance of final regulations during the second quarter of 2019 and did not recur in 2020. The discrete charge was partially offset by a benefit of $5.3 million recorded in the third quarter of 2019 based on the filing of the federal tax return. Additionally, in the second quarter of 2019, the Company received a termination fee from Versum based on the termination of the merger agreement between the Company and Versum. As a result of the termination fee, the Company released a valuation allowance on federal capital loss carryforwards and recorded a discrete benefit of $2.9 million, which did not recur in 2020.

40

Net income Net income was $295.0 million, or $2.16 per diluted share, in 2020 compared to net income of $254.9 million, or $1.87 per diluted share, in 2019. The increase 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.

Adjusted EBITDA increased to $542.5 million in 2020, compared to $436.8 million in 2019. Adjusted EBITDA as a percent of net sales was 29.2% in 2020 compared to 27.5% in 2019. Adjusted operating income increased 27% to $459.0 million in 2020, compared to $361.8 million in 2019. Adjusted operating income as a percent of net sales was 24.7% in 2020 compared to 22.7% in 2019. Non-GAAP EPS increased 32% to $2.54 in 2020, compared to $1.93 in 2019. The increases in the adjusted EBITDA and adjusted operating income as a percentage of net sales reflects the increase in sales and gross profit.

Segment Analysis

The Company reports its financial performance based on three reporting segments. See note 16 to the consolidated financial statements for additional information on the Company’s three segments.

The following table and discussion concern the results of operations of the Company’s three reportable segments for the years ended December 31, 2020 and 2019.

(In thousands)	2020		2019
Specialty Chemicals and Engineered Materials
Net sales	$	609,532	$	526,519

Segment profit	111,028		75,173
Unallocated general and administrative expenses	$	39,370	$	62,192

Specialty Chemicals and Engineered Materials (SCEM)

For 2020, SCEM net sales increased to $609.5 million, up 16% from $526.5 million in 2019. The sales increase was due to increased sales of advanced deposition materials, cleaning chemistries and advanced coatings, as well as additional sales of $25.6 million attributable to the acquisitions of Digital Specialty Chemicals Limited in the first quarter of 2019, MPD in the third quarter of 2019 and Sinmat in the first quarter of 2020.

SCEM reported a segment profit of $128.0 million for 2020, up 30% compared to a $98.3 million segment profit in 2019. The increase in the SCEM’s profit in 2020 was primarily due to higher sales levels and a $4.6 million reduction in cost of sales charges associated with the sale of inventory acquired in recent business acquisitions, partially offset by higher operating expenses by 6% mainly due to recent acquisitions and higher employee costs.

Microcontamination Control (MC)

For 2020, MC net sales increased to $742.2 million, up 17% from $633.7 million in 2019. The sales increase was due to improved sales of liquid filtration and gas filtration products, as well as additional sales of $11.0 million attributable to the acquisition of Anow in the third quarter of 2019, partially offset by decreased sales from bulk gas purification products.

MC reported a segment profit of $248.9 million for 2020, up 28% compared to a $194.4 million segment profit in 2019. The increase in MC’s profit in 2020 was primarily due to higher gross profit related to the increased sales volume and favorable product mix and a $2.6 million reduction in cost of sales charges associated with the sale of inventory acquired in recent

41

business acquisitions, partially offset by higher operating expenses of 10%, primarily due to higher compensations costs and the recent acquisition of Anow.

Advanced Materials Handling (AMH)

For 2020, AMH net sales increased 18% to $538.7 million from $458.3 million in 2019. This increase was mainly due to increased sales of high purity liquid containers, wafer handling products, fluid handling products and sensing and control products, as well as additional sales of $6.5 million attributable to the acquisition of GMTI in the third quarter of 2020.

AMH reported a segment profit of $111.0 million for 2020, up 48% compared to a $75.2 million segment profit in 2019. The increase in AMH’s profit in 2020 was primarily due to higher sales volume, favorable product mix and a 2% decrease in operating expenses, primarily due to lower spending and restructuring initiatives from the previous year.

Unallocated general and administrative expenses

Unallocated general and administrative expenses for 2020 totaled $39.4 million compared to $62.2 million for 2019. The $22.8 million decrease mainly reflects the decrease in deal and integration costs of $29.0 million noted in the discussion of SG&A above, offset partially by increased employee costs of $2.5 million, professional fees of $1.7 million and donation costs of $2.0 million.

Net sales For 2019, net sales were $1,591.1 million, up $40.6 million, or 3%, from sales for 2018. An analysis of the factors underlying the increase in net sales is presented in the following table:

(In thousands)
Net sales in 2018	$	1,550,497
Increase, net associated with acquired businesses and divestiture	95,003
Decrease associated with volume and pricing	(42,574)
Decrease associated with divestiture	(7,377)
Decrease associated with effect of foreign currency translation	(4,483)
Net sales in 2019	$	1,591,066

The Company’s sales increase was primarily due to sales associated with the Company’s recent acquisitions of $95.0 million, offset primarily by the absence of sales associated with a divestiture of an entity in 2018 and net unfavorable foreign currency

42

translation effects of $4.5 million, mainly due to the weakening of the Korean won, Euro and Taiwanese dollar relative to the U.S. dollar.

Sales percentage on a geographic basis for 2019 and 2018 and the percentage increase (decrease) in sales for 2019 compared to the sales for 2018 were as follows:

	Year ended
	December 31, 2019		December 31, 2018		Percentage increase (decrease) in sales
Taiwan	19	%	19	%	7	%
North America	24	%	22	%	10	%
South Korea	15	%	16	%	1	%
Japan	13	%	14	%	(2)	%
China	13	%	13	%	5	%
Europe	8	%	9	%	(4)	%
Southeast Asia	7	%	8	%	(12)	%

The increase in sales for North America and China was primarily driven by sales from acquisitions. The increase in sales from Taiwan was primarily driven from strong recovery from a major customer in 2019 compared to 2018. The decrease in sales from Europe relates to the absence of sales from the divestiture of a business in the fourth quarter of 2018. The decrease in sales from Southeast Asia relates to lower sales of specialty materials products.

Demand drivers for the Company’s business primarily consist of semiconductor fab utilization and production (unit-driven) as well as capital spending for new or upgraded semiconductor fabrication equipment and facilities (capital-driven). The Company analyzes sales of its products by these two key drivers. Sales of unit-driven products represented 70% of total sales and sales of capital-driven products represented 30% of total sales in both 2019 and 2018.

Gross profit Gross profit for 2019 decreased by $8.2 million, to $711.7 million, a decrease of 1% from $719.8 million for 2018. The gross margin rate for 2019 was 44.7% versus 46.4% for 2018. The gross profit and gross margin decrease reflects lower factory utilization associated with weaker sales levels and an unfavorable sales mix. The gross profit and gross margin figures include an incremental cost of sales charge of $7.5 million and $6.9 million, respectively, associated with the sale of inventory acquired in recent business acquisitions for 2019 and 2018 and $1.3 million and $0.5 million of restructuring charges for 2019 and 2018, respectively. Excluding those charges, the Company’s gross profit and gross margin for 2019 and 2018 were $720.5 million and $727.2 million, respectively, and 45.3% and 46.9%, respectively.

Selling, general and administrative expenses

Selling, general and administrative expense (SG&A) consists 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 2019 increased $38.3 million, or 16%, to $284.8 million from $246.5 million in 2018. SG&A expenses, as a percent of net sales, increased to 17.9% from 15.9% a year earlier, reflecting primarily from the increase in deal and integration costs.

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

(In thousands)
Selling, general and administrative expenses in 2018	$	246,534
Deal costs	21,043
Severance and restructuring costs	9,193
Integration costs	6,695
Professional fees	2,715
Travel costs	(2,192)
Other increases, net	819
Selling, general and administrative expenses in 2019	$	284,807

Engineering, research and development expenses

43

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 $121.1 million and $118.5 million in 2019 and 2018, respectively. ER&D expenses as a percent of net sales were 7.6% in both 2019 and 2018.

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

(In thousands)
Engineering, research and development expense in 2018	$	118,456
Employee costs	3,769
Severance and restructuring costs	1,965
Project related costs	(5,698)
Other increases, net	2,648
Engineering, research and development expense in 2019	$	121,140

The Company’s overall ER&D efforts will continue to focus on the support or extension of current product lines, the development of its technologies to create differentiated and high-value products for the most advanced and demanding semiconductor applications and leveraging its unique and diverse technology portfolio to develop innovative, integrated solutions for unmet customer needs. The Company expects ER&D costs to stay relatively stable as a percentage of net sales.

Amortization of intangible assets Amortization of intangible assets was $66.4 million in 2019 compared to $62.2 million for 2018. The increase reflects the additional amortization expense of $6.6 million associated with the Company’s recent 2019 and 2018 acquisitions as discussed in note 3 to the consolidated financial statements, offset primarily by the elimination of amortization expense of $2.0 million for identifiable developed technology and customer relationship assets acquired in the Poco acquisition.

Interest expense Interest expense was $47.0 million and $34.1 million in 2019 and 2018, respectively. Interest expense includes interest associated with debt outstanding and the amortization of debt issuance costs associated with such borrowings. The increase primarily reflects higher average debt levels in 2019 and a $1.6 million charge related the adjustment of the fair value of the fixed deferred payment owed to the sellers of its DSC acquisition. The Company entered into a settlement agreement to accelerate a fixed deferred payment of $16.1 million to no later than March 8, 2020. The Company adjusted the fair value of the fixed deferred payment from its fair value to the stated value resulting in the additional aforementioned charge.

Interest income Interest income was $4.7 million and $3.8 million in 2019 and 2018, respectively. The increase reflects higher average U.S. cash levels earning a higher rate of interest.

Other (income) expense, net Other income, net, was $121.1 million in 2019 compared to other expense, net, of $8.0 million in 2018.

In 2019, other income, net consisted mainly of net proceeds received of $122.0 million resulting from the termination of the merger agreement with Versum (see note 9 to the Company’s consolidated financial statements).

In 2018, other expense, net, included foreign currency transaction losses of $4.4 million, a loss of extinguishment of debt of $2.3 million associated with the redemption of the Company’s senior secured term loan facility due 2021 and asset-based revolving credit facility (see note 8 to the Company’s consolidated financial statements) and penalty charges of $1.1 million.

Income tax expense The Company recorded income tax expense of $63.2 million in 2019 compared to income tax expense of $13.7 million in 2018. The Company’s effective tax expense rate was 19.9% in 2019, compared to an effective tax rate of 5.4% in 2018.

The increase in the effective tax rate in 2019 from 2018 reflects several factors. The increase in the effective tax rate is primarily due to a $25.1 million benefit related to foreign tax credit generation and a $9.4 million benefit related to a dividends received deduction based on restructuring to simplify the legal entity structure in 2018 which did not recur in 2019. Additionally, the tax rate in 2019 includes a discrete tax charge of $9.4 million related to the reversal of the dividend received deduction benefit recorded in 2018. This discrete charge was recorded based on the issuance of final regulations during the second quarter of 2019. The discrete charge was partially offset by a benefit of $5.3 million recorded in the third quarter of 2019 based on the filing of the federal tax return. Additionally, in the second quarter 2019, the Company received a termination fee from Versum based on the termination of the Versum Merger Agreement. As a result of the termination fee, the Company released a valuation allowance on federal capital loss carryforwards and recorded a discrete benefit of $2.9 million.

Net income Net income was $254.9 million, or $1.87 per diluted share, in 2019 compared to net income of $240.8 million, or $1.69 per diluted share, in 2018. The increase 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 (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. 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 are Adjusted EBITDA and Adjusted Operating Income, together with related percentage changes, and non-GAAP Earnings Per Share (EPS).

Adjusted EBITDA was flat at $436.8 million in 2019, compared to $436.1 million in 2018. Adjusted EBITDA, as a percent of net sales, was 27.5% in 2019 compared to 28.1% in 2018. Adjusted Operating Income decreased 2% to $361.8 million in 2019, compared to $371.0 million in 2018. Adjusted Operating Income, as a percent of net sales, was 22.7% in 2019 compared to 23.9% in 2018. Non-GAAP Earnings Per Share increased 2% to $1.93 in 2019, compared to $1.89 in 2018. The decline in the Adjusted EBITDA and Adjusted Operating Income as a percentage of net sales reflects the decrease in gross profit. In addition, Non-GAAP Earnings Per Share was positively affected by lower diluted weighted average shares outstanding from the stock repurchases during 2019.

Segment Analysis

The Company reports its financial performance based on three reporting segments. In the first quarter of 2019, the Company changed its definition of segment profit to include inter-segment sales. Prior quarter information has been recast to reflect the change in the Company’s definition of segment profit. See note 16 to the consolidated financial statements for additional information on the Company’s three segments.

The following table and discussion concern the results of operations of the Company’s three reportable segments for the years ended December 31, 2019 and 2018.

(In thousands)	2019		2018
Specialty Chemicals and Engineered Materials
Net sales	$	526,519	$	530,241
Segment profit	98,327		127,080
Microcontamination Control
Net sales	$	633,664	$	553,838
Segment profit	194,398		166,852
Advanced Materials Handling
Net sales	$	458,290	$	493,404
Segment profit	75,173		92,327

Specialty Chemicals and Engineered Materials (SCEM)

For 2019, SCEM net sales decreased to $526.5 million, down 1%, from $530.2 million in the comparable period last year. The sales decrease was mainly due to decreased sales of specialty materials, specialty gases and surface prep and integration products, partially offset by $10.9 million of sales from the acquisition of DSC in 2019, $16.7 million sales from the acquisition of MPD in the third quarter of 2019 and improved sales from advanced deposition products.

SCEM reported a segment profit of $98.3 million for 2019, down 23%, compared to a $127.1 million segment profit in the year-ago period. The decrease in the SCEM’s profit in 2019 was primarily due to decreased sales, an incremental cost of sales charge of $6.9 million associated with the sale of inventory acquired in recent business acquisitions, unfavorable product mix and higher operating expenses of 3% mainly due to higher employee costs and R&D spending.

Microcontamination Control (MC)

For 2019, MC net sales increased to $633.7 million, up 14%, from $553.8 million in the comparable period last year. The sales increase was due to the acquisition of SPG in the second quarter of 2018, which contributed an additional $61.3 million of sales, $5.1 million of sales from the acquisition of Anow in the third quarter of 2019, and improved sales from liquid chemistry filters for wet, etch and clean applications and photolithography products, partially offset by weakened sales from gas microcontamination products.

MC reported a segment profit of $194.4 million for 2019, up 17%, compared to a $166.9 million segment profit in the year-ago period. The increase in MC’s profit in 2019 reflects increased sales, partially offset by higher operating expenses of 8%, primarily due to higher employee costs, increased R&D spending and SPG operating infrastructure.

45

Advanced Materials Handling (AMH)

For 2019, AMH net sales decreased 7% to $458.3 million, from $493.4 million in 2018. This decrease was mainly due to decreased sales of fluid handling products, liquid packaging and dispense products, wafer and reticle handling products and wafer shipping products.

AMH reported a segment profit of $75.2 million for 2019, down 19% compared to a $92.3 million segment profit in the year-ago period. The decrease in the AMH’s profit in 2019 was primarily due to lower sales.

Unallocated general and administrative expenses

Unallocated general and administrative expenses for 2019 totaled $62.2 million compared to $31.4 million for 2018. The $30.8 million increase mainly reflects the deal and integration costs of $27.7 million in the discussion of SG&A above.

The Company’s quarterly results of operations have been, and will likely continue to be, subject to significant fluctuations due to a myriad of factors, many of which are beyond the Company’s control. The variability in sales and its corresponding effect on gross profit are generally the most important factors underlying the changes in the Company’s operating income and net income over the past eight quarters.

Liquidity and Capital Resources

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

In thousands	December 31, 2020		December 31, 2019
Cash and cash equivalents	$	580,893	$	351,911
Working capital	931,631		667,964
Total debt	1,085,783		936,484

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. Although there is

uncertainty related to the anticipated impact of the COVID-19 pandemic on the Company’s future results, we believe our

business model, our current cash reserves and the recent steps we have taken to strengthen our balance sheet, such as our

issuance of $400 million aggregate principal amount of 4.375% senior unsecured notes due April 15, 2028 and related

repayments under the Revolving Facility and Term Loan Facility will help us to manage our business through the pandemic as we expect it to unfold. We have reviewed numerous potential scenarios in connection with the impact of COVID-19 on the global economy and the semiconductor industry. 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. As the opportunity arises, 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

47

the Company’s cash requirements. There can be no assurance that any such financing would be available on commercially acceptable terms, or at all. In recent quarters, we have not experienced difficulty accessing the capital and credit markets;

however, 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 thousands)	Year ended December 31, 2020		Year ended December 31, 2019		Year ended December 31, 2018
Net cash provided by operating activities	$	446,674	$	382,298	$	312,576
Net cash used in investing activities	(243,326)		(385,840)		(485,944)
Net cash provided by (used in) financing activities	22,149		(126,820)		34,411
Increase (decrease) in cash and cash equivalents	$	228,982	$	(130,151)	$	(143,346)

Operating activities

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

Compared to 2019, the $64.4 million increase in cash provided by operating activities in 2020 was primarily due to higher net income and changes in working capital. Changes in working capital for 2020 were driven by higher trade accounts receivables and notes receivable and inventory, offset by higher accounts payable and other accrued liabilities and income taxes. The change for trade accounts receivables and notes receivable was primarily due to increased sales activity compared to the prior year. The change for inventory is due to an increase in raw material purchases to mitigate potential supply chain issues related to COVID-19 and increased business activity. The change in accounts payable and accrued liabilities is primarily due to higher accrued bonuses in 2020 compared to 2019. The change for taxes was primarily driven by lower tax payments compared to the prior year.

Compared to 2018, the $69.7 million increase in cash provided by operating activities in 2019 was primarily due to higher net income, depreciation and changes in working capital. Depreciation expense increased due to higher levels of capital spending in prior years. Changes in working capital for 2019 were driven by income taxes and inventories, offset by accounts payable and other accrued liabilities. The change for taxes was primarily the result in 2018 tax credits that were utilized against a one time toll charge accrual recorded in 2017. The change for inventory is due to lower production activity in 2019 compared to 2018. The decrease in accounts payable and accrued liabilities is due to lower accrued bonuses in 2019 and lower payables due to timing of payments.

Investing activities

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

The decrease in cash used in investing activities in 2020 compared to 2019 was primarily due to lower cash paid for acquisitions. This was partially offset by increased acquisitions of property, plant and equipment.

The decrease in cash used in investing activities in 2019 compared to 2018 was primarily due to lower cash paid on acquisitions. This was partially offset by increased acquisitions of property, plant and equipment and lower proceeds from sales of property, plant and equipment.

Acquisition of property and equipment totaled $131.8 million in 2020, which primarily reflected investments in equipment and tooling, compared to $112.4 million in 2019, which primarily reflected investments in equipment and tooling. Capital expenditures in 2020 generally reflected more normalized capital spending levels. The Company expects its capital expenditures in 2021 to be approximately $200.0 million for growth capacity investments. Of this amount approximately $40.0 million will be spent for the first stage of a three to five year, $200.0 million investment in our new facility in Taiwan. This new facility will ultimately support all three of our divisions.

In 2020, the Company acquired Sinmat and GMTI. The cash used to acquire Sinmat and GMTI was $111.9 million, net of cash acquired. The transactions are described in further detail in note 3 to the Company’s consolidated financial statements.

In 2019, the Company acquired DSC, MPD and Anow. The cash used to acquire DSC, MPD and Anow was $277.4 million, net of cash acquired. The transactions are described in further detail in note 3 to the Company’s consolidated financial statements.

48

Financing activities

Financing cash flows consist primarily of repurchases of common stock, 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 2020, there was $22.1 million of cash provided by financing activities compared to $126.8 million cash used in financing activities in 2019. The change was primarily due to net long-term debt activity, which was a source of cash of $149.0 million in 2020 compared to a use of cash of $4.0 million in 2019, and a $35.8 million decrease of repurchases of the Company’s common stock, partially offset by a $16.1 million deferred acquisition payment related to our DSC acquisition, a $16.1 million increase in cash used to pay taxes for net share settlements of equity awards and a $4.0 million increase in payments for debt issuance costs. During 2020, we repurchased $44.6 million of common stock under our authorized common stock repurchase program, compared to $80.3 million in 2019. Our total dividend payments were $43.2 million in 2020 compared to $40.6 million in 2019. We have paid a cash dividend in each of the past 13 quarters. On January 13, 2021, the Company’s board of directors declared a quarterly cash dividend of $0.08 per share of common stock, payable on February 17, 2021 to stockholders of record on January 27, 2021.

In 2019, there was $126.8 million of cash used in financing activities compared to $34.4 million cash provided by financing

activities in 2018. The change was primarily due to net long-term debt activity, which was a use of cash of $4.0 million in 2019

compared to a source of cash of $266.2 million in 2018, primarily offset by decreased repurchases of common stock.

During 2019, we repurchased $80.3 million of our common stock under our authorized common stock repurchase program,

compared to $173.8 million in 2018. Our total dividend payments were $40.6 million in 2019 compared to $39.6

million in 2018.

Other Liquidity and Capital Resources Considerations

On April 30, 2020, the Company issued $400.0 million aggregate principal amount of 4.375% senior unsecured notes due April 15, 2028. The Company paid debt issuance costs of $4.0 million in connection with the issuance of the notes during 2020. The transaction is described in further detail in note 8 to the Company’s consolidated financial statements.

The Company’s Term Loan Facility matures on November 6, 2025 and bears an interest rate of 2.15% at December 31, 2020. During 2020, the Company made payments of $251.0 million on the Term Loan Facility and had losses on debt extinguishment of $2.4 million. As of December 31, 2020, the aggregate principal amount outstanding under the Term Loan Facility was $145.0 million.

The Company’s Revolving Facility provides for lending commitments in an aggregate principal amount of up to $300.0 million

maturing on November 6, 2023. The Revolving Facility bears interest at a rate per annum equal to, at the Company’s option,

either a base rate (such as prime rate) or LIBOR plus, in each case, an applicable margin. At December 31, 2020, there was no

balance outstanding under the Revolving Facility and we had undrawn outstanding letters of credit of $0.2 million.

As of December 31, 2020, we also had $550 million aggregate principal amount of 4.625% senior unsecured notes due February 10, 2026 outstanding.

Through December 31, 2020, the Company was in compliance with all applicable financial covenants included in the terms of its credit facilities.

The Company also has lines of credit with one bank that provides for borrowings of Japanese yen for the Company’s Japanese subsidiary equivalent to an aggregate of approximately $9.7 million. There were no outstanding borrowings under these lines of credit at December 31, 2020.

As of December 31, 2020, the Company’s sources of available funds were its cash and cash equivalents of $580.9 million, funds available under the Revolving Facility and international credit facilities and cash flows generated from operations. As of December 31, 2020, the amount of cash and cash equivalents held in certain of our foreign operations totaled approximately $312.8 million. We have accrued taxes on any earnings that are not indefinitely reinvested. We estimate that no material withholding taxes would be incurred if any indefinitely reinvested earnings were distributed.

Off-Balance Sheet Arrangements

As of December 31, 2020, we did not have any off-balance sheet arrangements that have, or are reasonably likely to have, a

material current or future effect on our financial condition, results of operations, liquidity, capital expenditures or capital

resources.

Unrecognized tax benefits(5)

1 Debt obligations are classified based on their stated maturity date, regardless of their classification on the Company’s consolidated balance sheets.

2 Interest projections on both variable and fixed rate long-term debt are based on interest rates effective as of December 31, 2020 and do not include $9.2 million for net unamortized discounts and debt issuance costs.  

3 Capital purchase obligations 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, 2020, as the Company had not yet received the related goods or taken title to the property.

4 Supply purchase obligations represent commitments, including take-or-pay contracts, that are not presented as capital purchase commitments above.

5 The Company had $17.4 million of total gross unrecognized tax benefits at December 31, 2020. The timing of any payments associated with these unrecognized tax benefits will depend on a number of factors. Accordingly, the Company cannot make reasonably reliable estimates of the amount and period of potential cash settlements, if any, with taxing authorities and are not included in the table above.

50

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

The Company also provides 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 earnings per share, as well as certain other supplemental non-GAAP financial measures included in the discussion of the Company’s financial results.

Adjusted EBITDA, a non-GAAP financial measure, is defined by the Company as net income before (1) income tax expense, (2) interest expense, (3) interest income, (4) other (income) expense, net, (5) charge for fair value write-up of acquired inventory sold, (6) deal costs, (7) integration costs, (8) severance and restructuring costs, (9) loss on sale of subsidiary, (10) amortization of intangible assets and (11) depreciation. Adjusted operating income, another non-GAAP financial measure, is defined by the Company as adjusted EBITDA exclusive of the depreciation addback noted above. The Company also utilizes non-GAAP financial measures whereby adjusted EBITDA and adjusted operating income are each divided by the Company’s net sales to derive adjusted EBITDA margin and adjusted operating margin, respectively.

Non-GAAP EPS, a non-GAAP financial measure, is defined by the Company as net income before (1) charge for fair value write-up of acquired inventory sold, (2) deal costs, (3) integration costs, (4) severance and restructuring costs, (5) loss on debt extinguishment and modification, (6) Versum termination fee, net, (7) loss on sale of subsidiary, (8) amortization of intangible assets, (9) the tax effect of those adjustments to net income and discrete tax items, (10) the tax effect of legal entity restructuring and (11) the tax effect of the Tax Cuts and Jobs Act, divided by diluted weighted average shares outstanding.

The Company provides supplemental non-GAAP financial measures to better understand and manage 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 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 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:

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, a significant recurring expense with an impact upon the Company’s results of operations, notwithstanding the lack of immediate impact upon cash flows.

51

Third, there is no assurance the Company will not have future restructuring activities, gains or losses on sale of equity investments, contingent consideration fair value adjustments 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 from 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, 2020, 2019 and 2018 are presented below:

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

Entegris’ principal financial market risks are sensitivities 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 are instruments with maturities of three months or less. A 100 basis point change in interest rates would potentially increase or decrease annual net income by approximately $3.4 million and $0.3 million annually for the years ended December 31, 2020 and 2019, 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 23.6% and 22.6% of the Company’s sales during 2020 and 2019 were denominated in the South Korean Won, New Taiwan Dollar, Chinese Renmibi, Canadian Dollar, Malaysian Ringgit, Singapore Dollar, Euro, Israeli Shekel and the Japanese Yen. Financial results therefore will be affected by changes in currency exchange rates. If all foreign currencies were to see a 10% reduction versus the U.S. dollar during the years ended December 31, 2020 and 2019 revenue would be negatively impacted by approximately $43.8 million and $36.0 million, respectively.

The Company occasionally uses derivative financial instruments to manage the foreign currency exchange rate risks associated with its foreign-based operations. At December 31, 2020 and 2019, the Company had no net exposure to any foreign currency forward contracts.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

53

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.

The Company acquired Sinmat and GMTI on January 10, 2020 and July 10, 2020, respectively. Neither of Sinmat or GMTI is significant to the Company’s financial statements. Management’s evaluation of disclosure controls and procedures excluded consideration of those disclosure controls and procedures subsumed within internal control over financial reporting for Sinmat and GMTI. Sinmat and GMTI had total assets of approximately $163 million at December 31, 2020 and net sales of approximately $15 million in 2020.

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, 2020 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, 2020. 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.

The Company acquired Sinmat and GMTI on January 10, 2020 and July 10, 2020, respectively. The Company is continuing to integrate Sinmat and GMTI into its internal control over financial reporting, and management’s evaluation of the effectiveness of the Company’s internal control over financial reporting excluded Sinmat and GMTI.

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 Committee of our Board of Directors.

KPMG LLP, the independent registered public accounting firm which audited the consolidated financial statements included in this annual report, has issued an attestation report on our internal control over financial reporting.

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 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.:

Opinion on Internal Control Over Financial Reporting

We have audited Entegris, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2020, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, 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, 2020, and the related notes (collectively, the consolidated financial statements), and our report dated February 5, 2021 expressed an unqualified opinion on those consolidated financial statements.

The Company acquired Sinmat and Global Measurement Technologies, Inc. during 2020, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020, Sinmat’s and Global Measurement Technologies, Inc.’s internal control over financial reporting associated with total assets of $163 million and total revenues of $15 million included in the consolidated financial statements of the Company as of and for the year ended December 31, 2020. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Sinmat and Global Measurement Technologies, Inc.

Basis for Opinion

The Company’s management is responsible 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 appearing under Item 9A of the Company’s December 31, 2020 Annual Report on Form 10-K. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. 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 audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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.

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.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Entegris, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Entegris, Inc. and subsidiaries (the Company) as of December 31, 2020 and 2019, 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, 2020, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 5, 2021 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 10 to the consolidated financial statements, the Company has changed its method of accounting for leases in 2019 due to the adoption of FASB Accounting Standard Codification (Topic 842) Leases.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

F-2

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.

Fair value of acquired customer relationships

As discussed in Note 3 to the consolidated financial statements, the Company accounts for acquired businesses using the acquisition method of accounting by recording assets and liabilities acquired at their respective fair values. During 2020, the Company acquired Sinmat for a total purchase price of $75.6 million, net of cash acquired, and the Company recorded an intangible asset for customer relationships of $33.9 million.

We identified the assessment of the fair value of acquired customer relationships as a critical audit matter. The key assumptions included: (1) future revenue growth rate, (2) future operating margin, and (3) discount rate. Testing the key assumptions underlying the estimate of the fair value of the customer relationships acquired involved a high degree of subjectivity.

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 over the Company’s acquisition process. This included controls over the development of the key assumptions. We evaluated the reasonableness of the Company’s selected future revenue growth rate and future operating margin by comparing those assumptions to the historical results of Sinmat and analyst reports about the Company, its peer companies, and the industry. We involved valuation specialists with specialized skills and knowledge who assisted in evaluating the Company’s discount rate by comparing the Company’s inputs to the discount rate to publicly available data for comparable entities and assessing the resulting discount rate. We performed sensitivity analyses over the key assumptions to assess the impact of change in those assumptions on the Company’s determination of fair value.

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

ENTEGRIS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2020

(1)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations Entegris, Inc. (Entegris or the Company) 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.

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 Doubtful Accounts 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 doubtful accounts that management believes is adequate to cover expected losses on trade receivables.

Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined by the first-in, first-out (FIFO) method.

Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating leases. Lease liabilities for operating leases are classified in “Other accrued liabilities” and “Long-term lease liabilities” in our consolidated balance sheet. We do not have material financing leases.

Operating assets and liabilities 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 includes prepaid lease payments and excludes 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.

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 on the straight-line method over the estimated useful lives of the assets. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and gains or losses are recognized in the same period. 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).

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.

The fair value of long-term debt, including current maturities, based upon models utilizing market observable (Level 2) inputs and credit risk, was $1,126.6 million at December 31, 2020 compared to the carrying amount of long-term debt, including current maturities, of $1,085.8 million at December 31, 2020.

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. The Company compares the carrying value of its reporting units, including goodwill, to their fair value. For reporting units in which the assessment indicates that it is more likely than not that the fair value is more than its carrying value, goodwill is not considered impaired. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired.

F-10

Based on its annual analysis, the Company determined there was no indication of impairment of goodwill and the estimated fair value of each reporting unit substantially exceeded its carrying value.

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 records derivatives as assets or liabilities on the balance sheet and measures such instruments at fair value. Changes in fair value of derivatives are recorded each period in the Company’s consolidated statements of operations.

The Company periodically enters into forward foreign currency contracts to reduce exposures relating to rate changes in certain foreign currencies. Certain exposures to credit losses related to counterparty nonperformance exist. However, the Company does not anticipate nonperformance by the counterparties since they are large, well-established financial institutions. None of these derivatives is accounted for as a hedge transaction. Accordingly, changes in the fair value of forward foreign currency contracts are recorded as other expense (income), net, in the Company’s consolidated statements of operations. The fair values of the Company’s derivative financial instruments are based on prices quoted by financial institutions for these instruments.

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 weighted 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 incurred are recorded in cost of sales in the Company’s consolidated statements of operations.

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.

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 (Loss) Comprehensive income (loss) 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

F-11

on available-for-sale investments, and minimum pension liability adjustments are included in accumulated other comprehensive loss. Comprehensive income (loss) and the components of accumulated other comprehensive loss are presented in the accompanying consolidated statements of comprehensive income (loss) and consolidated statements of equity.

Recent Accounting Pronouncements Adopted in 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities are required to use a new forward-looking “expected loss” model that replaced the current “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The Company adopted this new guidance in the first quarter of fiscal 2020. The adoption of ASU 2016-13 did not impact the consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The Company adopted this guidance in 2020. The adoption of ASU 2018-14 did not impact the consolidated financial statements.

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

(2) REVENUES

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 below.

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

Nature of goods and services The following is a description of principal activities from which the Company generates its revenues. The Company has three reportable segments. For more detailed information about reportable segments, see note 16 to the consolidated financial statements. For each of the three 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.

The Company generally recognizes revenue for sales of services when the Company has satisfied the performance obligation. The payment terms and revenue recognized is 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

F-12

contractual obligations. The Company periodically reviews the assumptions underlying its estimates of discounts and volume rebates and adjusts its revenues accordingly.

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 below until the performance obligations are satisfied.

The following table provides information about contract liabilities from contracts with customers. The contract liabilities are included in other accrued liabilities balance in the consolidated balance sheet.

2028 Senior Unsecured Notes

On April 30, 2020, the Company issued $400.0 million aggregate principal amount of 4.375% senior unsecured notes due April 15, 2028 (the “2028 Notes”). The 2028 Notes were issued under an indenture dated as of April 30, 2020 (the “2028 Notes Indenture”) by and among the Company, certain subsidiaries of the Company and Wells Fargo Bank, National Association, as trustee (the “2028 Notes Trustee”). Interest on the 2028 Notes is payable semi-annually in arrears on April 15 and October 15 of each year, commencing on October 15, 2020. The Company incurred debt issuance costs of $4.0 million in connection with the 2028 Notes. These costs are reported in the consolidated balance sheet as a direct deduction from the face amount of the 2028 Notes.

The 2028 Notes are guaranteed, jointly and severally, fully and unconditionally, on a senior unsecured basis, by the Company’s existing and future domestic subsidiaries, other than certain excluded subsidiaries, to the extent that such entities guarantee indebtedness under the Company’s senior secured term loan facility due 2025 and senior secured revolving credit facility due 2023 (together, the “Senior Secured Credit Facilities”) or the Company’s 4.625% senior unsecured notes due 2026 (the “2026 Notes”) and any other subsidiary of the Company to the extent it incurs certain additional indebtedness (collectively, the “Guarantors”).

The 2028 Notes and the guarantees thereof are the Company’s and the Guarantors’ senior unsecured obligations, respectively, and will (i) rank equally in right of payment with all of the Company’s and the Guarantors’ existing and future senior

F-19

indebtedness (including the 2026 Notes); (ii) rank senior to any subordinated indebtedness that the Company or the Guarantors may incur; (iii) be effectively subordinated to all of the Company’s or the Guarantors’ existing and future secured indebtedness (including the Senior Secured Credit Facilities), in each case, to the extent of the value of the assets securing such indebtedness; and (iv) be structurally subordinated in right of payment to all existing and future obligations of the Company’s subsidiaries that do not guarantee the 2028 Notes.

At any time prior to April 15, 2023, the Company may, at its option, on any one or more occasions, redeem up to 40% of the aggregate principal amount of the 2028 Notes, at a redemption price equal to 104.375% of the principal amount of the 2028 Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, with an amount of cash equal to the net cash proceeds of an equity offering, as defined in the 2028 Notes Indenture, by the Company; provided that (1) at least 60% of the aggregate principal amount of 2028 Notes issued under the 2028 Notes Indenture remains outstanding immediately after the occurrence of each such redemption; and (2) the redemption occurs within 120 days of the date of the closing of such equity offering.

Additionally, at any time prior to April 15, 2023, the 2028 Notes may be redeemed, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of the 2028 Notes redeemed, plus a “make whole” premium, plus accrued and unpaid interest to, but not including, the applicable redemption date.

On or after April 15, 2023, the Company may on any one or more occasions redeem all or a part of the 2028 Notes, at its option, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the 2028 Notes redeemed, to, but not including, the applicable date of redemption, if redeemed during the 12-month period beginning on April 15 of the years indicated below:

Year	Percentage
2023	102.188	%
2024	101.094	%
2025 and thereafter	100.000	%

Upon the occurrence of certain change of control events accompanied by certain ratings events, the Company will be required to offer to repurchase all of the outstanding 2028 Notes at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

The 2028 Notes Indenture that governs the 2028 Notes contains covenants that, among other things, limit the Company’s ability and/or the ability of the Company’s subsidiaries to incur liens, engage in sale and leaseback transactions and consolidate, merge with or convey, transfer or lease all or substantially all of the Company’s and its subsidiaries’ assets to another person. The 2028 Notes Indenture also, subject to certain exceptions, limits the ability of any non-Guarantor subsidiary of the Company to incur indebtedness. These covenants are subject to a number of other limitations and exceptions as set forth in the 2028 Notes Indenture. The Company is in compliance with all of the above covenants at December 31, 2020.

The 2028 Notes Indenture provides for events of default which, if certain of them occur, would permit the 2028 Notes Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2028 Notes to declare the principal of, and interest or premium, if any, and any other monetary obligations on, all the then-outstanding 2028 Notes to be due and payable immediately.

2026 Senior Unsecured Notes

On November 10, 2017, the Company issued $550 million aggregate principal amount of 4.625% senior unsecured notes due February 10, 2026 (“the 2026 Notes”). The 2026 Notes were issued under an indenture dated as of November 10, 2017 (the “2026 Notes Indenture”) by and among the Company and Wells Fargo Bank, National Association, as trustee. Interest on the 2026 Notes is payable semi-annually in arrears on February 15 and August 15, which commenced on February 15, 2018.

The 2026 Notes are guaranteed, jointly and severally, fully and unconditionally, on a senior unsecured basis, by, subject to certain exclusions, each of the Company’s domestic subsidiaries that guarantee indebtedness under the New Credit Facilities.

As provided in the 2026 Notes Indenture, the Company may at its option on one or more occasions redeem all or a part of the 2026 Notes at a redemption price equal to (a) 100% of the principal amount of the 2026 Notes redeemed plus a make-whole premium if redeemed prior to November 10, 2020, or (b) 100% of the principal amount of the 2026 Notes redeemed plus a percentage of principal amount between 100% and 103.469% of the aggregate principal amount of the 2026 Notes to be redeemed, depending on the period of redemption, if redeemed on or after November 10, 2020, plus, in each case, accrued and unpaid interest on the amount of 2026 Notes being redeemed.

F-20

Upon a change in control accompanied by certain rating events, the Company is required to offer to repurchase all of the 2026 Notes at a price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

The 2026 Notes Indenture contains covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of the Company’s restricted subsidiaries to create liens, enter into sale and leaseback transactions, engage in consolidations or mergers, or sell, transfer or otherwise dispose of all or substantially all of their assets. The 2026 Notes Indenture also, subject to certain exceptions, limits the ability of any subsidiary of the Company that is not a guarantor under the 2026 Notes to incur indebtedness. The Company is in compliance with all of the above covenants at December 31, 2020.

The 2026 Notes Indenture also provides for events of default which, if certain of them occur, would permit the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2026 Notes to declare the principal, premium, if any, interest and any other monetary obligations on all the then-outstanding 2026 Notes to be due and payable immediately.

Senior Secured Credit Facilities

On November 6, 2018, the Company entered into a credit and guaranty agreement with Goldman Sachs Bank USA, as administrative agent and collateral agent, and added two additional lenders to the lenders party thereto. The credit agreement was amended in October 2019 (as so amended, the “Credit Agreement”) to change the administrative agent and collateral agent to Morgan Stanley and add two lenders. The Credit Agreement provides senior secured financing in an aggregate principal amount of $700 million, consisting initially of (a) term loans in an aggregate principal amount of $400 million (the “New Term Loan Facility”) and (b) revolving commitments in an aggregate amount of $300 million (the “New Revolving Facility”, and together with the New Term Loan Facility, the “New Credit Facilities”). Borrowings under the New Credit Facilities bear interest at a rate per annum equal to, at the Company’s option, a base rate (such as prime rate or LIBOR) plus an applicable margin. The Company’s interest rate on the term loans under the New Term Loan Facility is 2.15% at December 31, 2020. In addition to paying interest on the outstanding principal under the New Credit Facilities, the Company will pay (i) with respect to the New Term Loan Facility, customary agency fees, and (ii) with respect to the New Revolving Facility, a commitment fee in respect of the unutilized commitments thereunder and customary letter of credit fees and agency fees. The initial commitment fee is 0.20% per annum.

Debt issuance costs of $5.1 million for the year ended December 31, 2018 were paid to third parties and are capitalized as debt issuance costs in connection with the New Credit Facilities. These debt issuance costs are being amortized as interest expense in the Company’s consolidated statements of operations over the term of the debt instrument using the straight-line method.

The Company may voluntarily prepay outstanding term loans and revolving loans under the New Credit Facilities and may reduce the unutilized portion of the New Revolving Facility at any time without premium or penalty other than customary “breakage” costs with respect to LIBOR loans.

At present LIBOR is expected to be published only on a limited basis after 2021. The Company’s New Credit Facilities do not specify a particular “hard-wired” replacement index rate (or related margin) when LIBOR becomes unavailable, but rely on the administrative agent and the Company reaching agreement on such a replacement rate (and related margin) that gives due consideration to the then prevailing market convention for determining rates of interest for syndicated loans denominated in US dollars in the United States. The Company expects to amend the New Credit Facilities to provide a market-based replacement index rate and margin prior to the time when LIBOR is no longer available.

The Credit Agreement also requires the Company to prepay outstanding term loans, subject to certain exceptions, with (a) up to 50% of the Company’s annual Excess Cash Flow (as defined in the Credit Agreement) and (b) 100% of the net cash proceeds of (i) certain asset sales and casualty and condemnation events, subject to reinvestment rights and certain other exceptions; and (ii) any incurrence or issuance of certain debt, other than debt permitted under the New Credit Facilities.

The New Term Loan Facility matures November 6, 2025 and the New Revolving Facility matures November 6, 2023. At December 31, 2020, the only outstanding amounts under the New Revolving Facility were undrawn outstanding letters of credit of $0.2 million.

All obligations under the New Credit Facilities are unconditionally guaranteed by certain of the Company’s wholly-owned domestic subsidiaries and are secured, subject to certain exceptions, by substantially all of the Company’s assets and the assets of the Company’s subsidiaries that have guaranteed the New Credit Facilities.

The New Credit Facilities contain a number of negative covenants that, subject to certain exceptions, restrict the Company’s ability and each of the Company’s subsidiaries’ ability to incur additional indebtedness; pay dividends on its capital stock or redeem, repurchase or retire its capital stock or its other indebtedness; make investments, loans and acquisitions, create restrictions on the payment of dividends or other amounts to the Company from the Company’s restricted subsidiaries; engage in transactions with its affiliates; sell assets, including capital stock of its subsidiaries; materially alter the business it conducts; consolidate or merge; incur liens; and engage in sale-leaseback transactions. If at any time, commencing with the fiscal quarter

F-21

ending March 31, 2019, the Company has revolving borrowings, unreimbursed letter of credit drawings and undrawn letters of credit outstanding in an amount in excess of 35.0% of the commitment amount under the New Revolving Facility, the Credit Agreement requires the Company to maintain a secured net leverage ratio of at least 3.25 to 1.0. The Company is in compliance with all of the above covenants at December 31, 2020.

On January 28, 2019, the Company and Versum announced that they had entered into an Agreement and Plan of Merger, dated as of January 27, 2019 (the “Merger Agreement”), pursuant to which they agreed to combine in a merger of equals. On April 8, 2019, Versum announced that its Board of Directors had received a proposal from Merck KGaA to acquire Versum and that its Board of Directors had deemed such proposal as a “Superior Proposal” as defined in the Merger Agreement. On April 12, 2019, the Company received a termination notice from Versum terminating the Merger Agreement. In accordance with the terms of the Merger Agreement, Entegris received a $140.0 million termination fee from Versum in the second quarter of 2019. Also in the second quarter of 2019, the Company paid a fee of $18.0 million to the third-party financial adviser it had engaged to assist with the transaction.

(10)    LEASES

Adoption of ASC ASU No. 2016-02, Leases On January 1, 2019, the Company adopted ASU No. 2016-02 using the modified retrospective method applied to existing leases in place as of January 1, 2019. Leases entered into after January 1, 2019 are presented under the provisions of ASU No. 2016-02, while prior periods are not adjusted and continue to be reported in accordance with previous accounting guidance. Leases commencing or renewing after the adoption date are evaluated based on the guidance in ASU No. 2016-02 and may result in more finance leases being recognized even for the renewal of previously classified operating leases.

The Company elected to adopt the ‘package of practical expedients’, which permitted the Company not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the practical expedient pertaining to land easements, which allowed the Company to exclude evaluation of all existing land easements in connection with the adoption of the new lease requirements to assess whether they meet the definition of a lease. The Company did not elect the use-of-hindsight practical expedient and therefore did not reassess the lease terms for purposes of calculation of the lease liabilities and right-of-use assets at the adoption date. The Company elected the short-term lease recognition exemption for all leases that qualified. This means, for those leases that qualified, the Company did not recognize right-of-use assets or lease liabilities, and this included not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all leases other than leases of real estate, and this included not separating lease and non-lease components for all leases other than leases of real estate in transition.

The Company adopted ASU 2016-02 using the modified retrospective method, recognizing the cumulative effect of application as an adjustment to the opening balance sheet. The standard had a material impact on our consolidated balance sheets, but did not have a material impact on our consolidated statement of income or cash flows. The most significant impact was the recognition of the right-of-use asset and lease liabilities for operating leases. As of December 31, 2020 and 2019, we do not have any material finance leases.

Leases As of December 31, 2020, the Company was obligated under operating lease agreements for certain sales offices and manufacturing facilities, manufacturing equipment, vehicles, information technology equipment and warehouse space. Our leases have remaining lease terms of 1 year to 14 years, some of which may include options to extend the lease for up to 6 years, and some of which may include options to terminate the leases within 1 year.

As of December 31, 2020 and 2019, the Company’s operating lease components with initial or remaining terms in excess of one year were classified on the consolidated balance sheet as follows, together with certain supplemental balance sheet information:

In 2012, Entegris’ Korean subsidiary made commitments to produce a certain line of products in Korea. In return for this commitment, the Company had a tax holiday on income earned on sales of these products for five years and a partial holiday for two additional years. The income tax benefit attributable to this tax holiday was $4 million ($0.03 per diluted share) for the year ended December 31, 2018. The tax holiday benefit ceased during the year ended December 31, 2018.

The Company has made employment and spending commitments to Singapore. In return for those commitments, the Company has been 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 $9.4 million ($0.07 per diluted share), $5.8 million ($0.04 per diluted share) and $6.3 million ($0.04 per diluted share) for the years

F-24

ending December 31, 2020, 2019 and 2018, respectively. The 2020, 2019 and 2018 effective tax rates include additional benefits of $5.4 million, $3.3 million and $3.6 million, because the corporate tax rate in Singapore is lower than the U.S. rate.

At December 31, 2020, there were approximately $66.6 million of accumulated undistributed earnings of subsidiaries outside of the United States, all of which are considered to be indefinitely reinvested. Management estimates that no material 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, 2020 and 2019 are as follows:

(In thousands)	2020		2019
Deferred tax assets attributable to:
Accounts receivable	$	436	$	87

Accruals not currently deductible for tax purposes	12,828		7,568

Total deferred tax liabilities	(51,359)		(50,938)
Net deferred tax liabilities	$	(19,916)	$	(24,711)

Deferred tax assets are generally required to be reduced by a valuation allowance if, based on the weight of available positive and negative evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

As of December 31, 2020 and 2019, the Company had net U.S. deferred tax liabilities of $4.7 million and $12.2 million, respectively, which are composed of temporary differences and various tax credit carryforwards. Management believes that it is more likely than not that the benefit from certain state net operating loss carryforwards, state credit carryforwards and the federal foreign tax credit carryforward will not be realized. In recognition of this risk, management has provided valuation allowances of $18.6 million and $10.4 million as of December 31, 2020 and 2019, 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, 2020 will be recognized as a reduction of income tax expense.

At December 31, 2020, the Company had state operating loss and credit carryforwards of approximately $12.4 million, which begin to expire in 2021, and foreign operating loss carryforwards of $30.2 million, which begin to expire in 2021.

As of December 31, 2020 and 2019, the Company had net non-U.S. deferred tax assets of $14.1 million and $7.7 million, respectively, for which management determined based upon the available evidence a valuation allowance of $10.8 million and $9.7 million as of December 31, 2020 and 2019, 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.

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, 2020 and 2019 are as follows:

F-25

(In thousands)	2020		2019
Gross unrecognized tax benefits at beginning of year	$	16,194	$	12,295

Lapse in statute of limitations	(1,689)		(826)
Gross unrecognized tax benefits at end of year	$	17,395	$	16,194

The total amount of net unrecognized tax benefits that, if recognized, would effect the effective tax rate was $12.9 million at December 31, 2020.

Penalties and interest paid or received are recorded in other income, net in the consolidated statements of operations. As of December 31, 2020 and 2019, the Company had accrued interest and penalties related to unrecognized tax benefits of $4.9 million and $3.9 million, respectively. Expenses of $0.9 million, $0.6 million and $0.8 million were recognized as interest and penalties in the consolidated statements of operations for the years ended December 31, 2020, 2019 and 2018, 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 2016 and 2016, 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 2014.

Due to the expiration of various statutes of limitations and settlement of audits, it is reasonably possible that the Company’s gross unrecognized tax benefit balance may decrease within the next twelve months by approximately $2.3 million.

Share Repurchase Program

On December 14, 2020, the Company’s Board of Directors authorized a repurchase program, effective February 16, 2021, covering the repurchase of up to an aggregate of $125.0 million of the Company’s common stock, during a period of twelve months, in open market transactions and in accordance with one or more pre-arranged stock trading plans to be established in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. This repurchase program replaced the existing repurchase program, which was originally approved in February 2020 and which will expire pursuant to its terms on February 15, 2021.

The Company repurchased $44.6 million, $74.8 million and $179.3 million of shares for the years ended December 31, 2020, 2019 and 2018, respectively.

The credit agreement governing the New Credit Facilities contains restrictions that may limit the Company’s ability to continue to repurchase shares.

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,

F-26

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.

Options outstanding for the Company’s stock plans at December 31, 2020 are summarized as follows:

(Shares in thousands)	Options outstanding				Options exercisable
Range of exercise prices	Number outstanding	Weighted average remaining life in years	Weighted- average exercise price		Number exercisable	Weighted average exercise price

	1,082	4.4 years	$	33.38	426	$	24.99

The weighted average remaining contractual term for options outstanding and options exercisable for all plans at December 31, 2020 was 4.4 years and 3.6 years, respectively.

For all plans, the Company had shares available for future grants of 9.0 million, 8.2 million, and 8.7 million shares at December 31, 2020, 2019 and 2018, respectively.

Under the stock plans, the total pre-tax intrinsic value of stock options exercised during the years ended December 31, 2020 and 2019 was $36.4 million and $3.2 million, respectively. The aggregate intrinsic value, which represents the total pre-tax intrinsic value based on the Company’s closing stock price of $96.10 at December 31, 2020, which theoretically could have been received by the option holders had all option holders exercised their options as of that date, was $67.9 million and $30.3 million for options outstanding and options exercisable, respectively.

Share-based payment awards in the form of stock option awards for 0.2 million, 0.3 million and 0.3 million shares were granted to employees during the years ended December 31, 2020, 2019 and 2018, respectively. Compensation expense is based on the grant date fair value. The awards vest annually over a four-year period 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, 2020, 2019 and 2018:

F-27

Employee stock options:	2020			2019			2018
Volatility	31.9		%	31.6		%	28.7		%
Risk-free interest rate	1.4		%	2.5		%	2.4		%
Dividend yield	0.6		%	0.8		%	0.9		%
Expected life (years)	4.3			4.1			3.9
Weighted average fair value per option	$	14.83		$	8.89		$	7.35

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 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 maintains the Entegris, Inc. Amended and Restated Employee Stock Purchase Plan (“ESPP”). The 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, 2020, 1.5 million shares remained available for issuance under the ESPP. Employees purchased 0.2 million, 0.2 million and 0.2 million shares, at a weighted-average price of $46.58, $28.67, and $24.86 during the years ended December 31, 2020, 2019 and 2018, 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, 2020, 2019 and 2018 is presented in the following table:

	2020			2019			2018
(Shares in thousands)	Number of shares	Weighted average grant date fair value		Number of shares	Weighted average grant date fair value		Number of shares	Weighted average grant date fair value
Unvested, beginning of year	1,254	$	27.48	1,519	$	21.24	1,857	$	15.86
Granted	437	57.46		514	34.05		509	31.40
Vested	(564)	23.48		(679)	18.89		(732)	15.07
Forfeited	(44)	35.86		(100)	24.82		(115)	18.58
Unvested, end of year	1,083	41.31		1,254	27.48		1,519	21.24

The weighted average remaining contractual term for unvested restricted shares at December 31, 2020 and 2019 was 1.2 years and 1.1 years, respectively.

During the years ended December 31, 2020, 2019 and 2018, the Company awarded performance-based restricted stock units for up to 0.1 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 and other key employees. Compensation expense is based on the grant date fair value. The awards vest on the third anniversary of the award date. The Company estimates the fair value of the performance shares using a Monte Carlo simulation process.

As of December 31, 2020, the total compensation cost related to unvested stock options, performance-based restricted stock units and restricted stock unit awards not yet recognized was $3.9 million, $3.4 million and $30.6 million, respectively, and is expected to be recognized over the next 2.5 years on a weighted-average basis.

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. The following table summarizes the allocation of share-based compensation expense related to employee stock options,

401(k) Plan

The Company maintains the Entegris, Inc. 401(k) Savings and Profit Sharing Plan (the “401(k) Plan”) that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the Plan, eligible employees may defer a portion of their pre-tax wages, up to the Internal Revenue Service annual contribution limit. Entegris matches employees’ contributions to a maximum match of 4% of the employee’s eligible wages. The employer matching contribution expense under the 401(k)Plan was $8.2 million, $7.1 million and $6.1 million in the fiscal years ended December 31, 2020, 2019 and 2018, respectively.

Assumptions used in determining the benefit obligation and net periodic benefit cost for the Company’s pension plans for the years ended December 31, 2020, 2019 and 2018 are presented in the following table as weighted-averages:

	2020		2019		2018
Benefit obligations:
Discount rate	0.39	%	0.53	%	0.76	%
Rate of compensation increase	2.33	%	2.91	%	3.08	%
Net periodic benefit cost:
Discount rate	0.98	%	1.29	%	1.66	%
Rate of compensation increase	2.33	%	3.51	%	3.18	%
Expected return on plan assets	1.82	%	1.51	%	1.89	%

The pension plans’ expected return on assets as shown above is based on management’s expectations of long-term average rates of return to be achieved by the underlying investment portfolios. In establishing this assumption, management considers historical and expected returns for the asset classes in which the plans are invested, as well as current economic and capital market conditions. The discount rate primarily used by the Company is based on market yields at the valuation date on government bonds as well as the estimated maturity of benefit payments.

Plan Assets

At December 31, 2020, the majority of the Company’s pension plan assets are deposited with the Bank of Taiwan in the form of money market funds, where the Bank of Taiwan is the assigned funding vehicle for the statutory retirement benefit. The remaining portion of the Company’s plan assets is deposited in a German insurance company’s investment fund.

    In consideration of services rendered to Entegris, Inc. (the “Company”), the Company may periodically make equity incentive awards consisting of restricted stock units with respect to the Company’s Common Stock, $0.01 par value (“Stock”), to certain key employees, non-employee directors, consultants or advisors of the Company under the Company’s 2020 Stock Plan (as amended from time to time, the “Plan”). Any key employee, non-employee director, consultant or advisor (a “Participant”) who receives a restricted stock unit award (the “Award”) is notified in writing or via email alert. The Award is credited to the Participant’s account and reflected under the Stock Plans section on Fidelity’s NetBenefits website. To Accept the award; click on the “Begin your grant acceptance now” link located in the New Grant Alert notification or scroll down to and expand the Stock Plans section; then click on “Begin Acceptance” and follow the prompts. By accepting the Award, Participant: (i) acknowledges that Participant has received a copy of the Plan, of the related prospectus providing information concerning awards under the Plan and of the Company’s most recent Annual Report on Form 10-K; and (ii) accepts the Award and agrees with the Company that the Award is subject to the terms of the Plan and to the following terms and conditions:

Article I – RSU Award

1.1. Award Date. This Agreement shall take effect as of the date specified in the Stock Plans section as of the Award Date provided to you online through Fidelity’s NetBenefits website (the “Award Date”).

1.2. Restricted Stock Units Subject to Award. The Award consists of that number of restricted stock units (the “RSU”) with respect to the Stock that has been approved for the Award to Participant by the Administrator. Each RSU is equivalent to one share of the Stock. The Participant’s rights to the RSU are subject to the restrictions described in this Agreement and in the Plan (which is incorporated herein by reference with the same effect as if set forth herein in full) in addition to such other restrictions, if any, as may be imposed by law.

1.3. Meaning of Certain Terms. The term “vest” as used herein with respect to any RSU means the lapsing of the restrictions described herein with respect to such RSU.

1.4. Nontransferability of RSUs. The RSU acquired by the Participant pursuant to this Agreement shall not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of except as provided below and in the Plan.

1.5. Forfeiture Risk. Except as otherwise provided in this Agreement, if the Participant ceases to be employed or retained by the Company or an Affiliate for any reason, any then-outstanding and unvested RSU acquired by the Participant hereunder shall be automatically and immediately forfeited. The Participant hereby appoints the Company as the attorney-in-fact of the Participant to take such actions as may be necessary or appropriate to effectuate the cancellation of a forfeited RSU.

1.6. Vesting and Settlement of RSUs. The RSU acquired hereunder shall vest in accordance with the provisions of this Article I, Section 1.6 and applicable provisions of the Plan, as follows:

•25% of the RSUs vest on ;

•an additional 25% of the RSUs vest on ;

•an additional 25% of the RSUs vest on ; and

•the final 25% of the RSUs vest on .

Notwithstanding the foregoing, no RSU shall vest on any vesting date specified above unless: (A) the Participant is then, and since the Award Date has continuously been, employed or retained by the Company or an Affiliate (subject to Sections 2.2 and 2.3); and (B) the Participant has fulfilled the obligations specified in Section 1.9 below. Upon vesting, each RSU shall entitle Participant to receive one share of Stock (subject to adjustment under the Plan).

Vested RSUs shall be settled in shares of Stock (or, in the discretion of the Administrator, in cash equal to the Fair Market Value thereof). Subject to Section 2.12, settlement and delivery of the applicable number of shares of Stock (or cash equivalent, if applicable) shall be made as soon as practicable following vesting, but in no event later than 30 days after the applicable vesting date. No fractional shares of Stock shall be issued pursuant to this Agreement.

1.7. Dividend Equivalent Rights. The Participant shall not be entitled: (i) to receive any dividends or other distributions paid with respect to the Stock to which the RSU relates, or (ii) to vote any Stock with respect to which the RSU relates, unless and until, and only to the extent, the RSU becomes vested and the Participant becomes a stockholder of record with respect to such shares of Stock. Notwithstanding the foregoing, as of each date on which the Company pays an ordinary cash dividend to record owners of shares of Stock, the Participant’s account shall, as of each such dividend date, be credited with a cash amount (without interest) equal to the product of the total number of shares subject to the RSU immediately prior to such dividend date multiplied by the dollar amount of the cash dividend paid per share of Stock by the Company on such dividend date (such amount, the “Dividend Equivalent Amount”). The Dividend Equivalent Amount shall be subject to the same vesting conditions and settlement terms as the RSU shares to which they relate.

1.8. Sale of Vested Shares. The Participant understands that Participant will be free to sell any Stock with respect to which the RSU relates once the RSU has vested and settled, subject to (i) satisfaction of any applicable tax withholding requirements with respect to the vesting of such RSU; (ii) the completion of any administrative steps (for example, but without limitation, the transfer of certificates) that the Company may reasonably impose; and (iii) applicable requirements of federal and state securities laws.

1.9. Certain Tax Matters. The Participant expressly acknowledges that the award or vesting of the RSU acquired hereunder may give rise to income subject to withholding. The Participant expressly acknowledges and agrees that Participant’s rights hereunder are subject to Participant promptly paying to the Company all taxes required to be withheld in

    -2-

connection with such award, vesting, settlement and/or payment. Unless the Administrator determines otherwise, such payment of Participant’s withholding tax obligations shall be made through net share settlement procedures whereby that number of the vesting shares needed to cover the withholding tax obligation (calculated using the Fair Market Value of the Company’s stock on the date of vesting) shall be cancelled to fund the Company’s payment of the withholding tax obligation and the net shares remaining after such cancellation shall be credited to Participant’s account.

Article II – GENERAL PROVISIONS

2.1. Definitions. Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan.

2.2. Change in Control

        (a)    Assumption or Substitution.

            (i)     If the Change in Control is one in which there is an acquiring or surviving entity, the Administrator may provide for the assumption or continuation of some or all outstanding Awards or for the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor.

            (ii)    Only to the extent consistent with Section 409A of the Code, in the event of a Change in Control in which the successor company assumes or substitutes for the RSU (or in which the Company is the ultimate parent corporation and continues the Award), if Participant’s employment with such successor company (or the Company) or an affiliate thereof is involuntarily terminated without Cause by the successor employer or Participant resigns for Good Reason, in either case within 24 months following such Change in Control: the restrictions, limitations and other conditions applicable to the RSU shall lapse and the RSU shall become free of all restrictions, limitations and conditions and become fully vested.

        (b)    Awards Not Assumed or Substituted. In the event of a Change in Control in which the successor company does not assume or substitute for the RSU (or in which the Company is the ultimate parent corporation and does not continue the Award): the restrictions, limitations and other conditions applicable to the RSU shall lapse and the RSU shall become free of all restrictions, limitations and conditions and become fully vested, provided that if the RSU constitutes nonqualified deferred compensation pursuant to Section 409A, the RSU will not be settled until the earliest to occur of the regularly scheduled vesting date, Participant’s retirement in accordance with Section 2.3 and Participant’s termination without Cause or for Good Reason, subject to application of a six-month delay if the Participant is a specified employee under Section 409A.

        (c)    Good Reason Definition. For purposes of this Section 2.2, “Good Reason” means (i) “Good Reason” as defined in any individual agreement to which Participant and the Company or an Affiliate are parties, or (ii) if there is no such agreement or if it does not

    -3-

define Good Reason, without the Participant’s prior written consent: (A) a reduction in the Participant’s base salary; (B) a relocation of the Participant’s primary work location to a distance of more than 50 miles from its location as of immediately prior to such change; or (C) a material breach by the Company or an Affiliate of any employment agreement with the Participant. In order to invoke a termination of employment for Good Reason, a Participant shall provide written notice to the Company of the existence of one or more of the conditions described in clauses (A) through (C) within 90 days following the Participant’s knowledge of the initial existence of such condition or conditions, and the Company shall have 30 days following receipt of such written notice (the “Cure Period”) during which it may remedy the condition(s). In the event that the Company fails to remedy the condition(s) constituting Good Reason during the Cure Period, the Participant must terminate employment, if at all, within 90 days following the Cure Period in order for such termination to constitute a termination of employment for Good Reason.

    (d)    Cause Definition. “Cause” means (i) “Cause” as defined in any individual agreement to which the Participant and the Company or an Affiliate are parties or (ii) if there is no such agreement or if it does not define Cause, the Company’s termination of the Participant’s employment with the Company or any Affiliate following the occurrence of any one or more of the following: (A) the Participant’s conviction of, or plea of guilty or nolo contendere to, a felony; (B) the Participant’s willful and continual failure to substantially perform the Participant’s duties after written notification by the Company; (C) the Participant’s willful engagement in conduct that is materially injurious to the Company or an Affiliate monetarily or otherwise; (D) the Participant’s commission of an act of gross misconduct in connection with the performance of the Participant’s duties; or (E) the Participant’s material breach of any employment, confidentiality, or other similar agreement between the Company or an Affiliates and the Participant.

2.3. Retirement. If Participant is an employee of the Company or Affiliate and ceases to be an employee due to retirement with the consent of the Administrator, Participant will be entitled to immediate vesting of all unvested RSUs awarded pursuant to this Agreement. As used herein the term “retirement with the consent of the Administrator” means that Participant’s retirement must be with the consent of the Administrator, which consent may be granted or withheld in the discretion of the Administrator. In the event that Participant ceases to be an employee under circumstances that would otherwise qualify for retirement but the consent of the Administrator has not been granted, then Participant shall not be entitled to the benefits of this Section 2.3.

2.4. Equitable Adjustments. The Award is subject to adjustment pursuant to Section 15.1 of the Plan.

2.5. No Understandings as to Employment etc. The Participant further expressly acknowledges that nothing in the Plan or any modification thereto, in the Award or in this Agreement shall constitute or be evidence of any understanding, express or implied, on the part of the Company to employ or retain the Participant for any period or with respect to the terms of the Participant’s employment or to give rise to any right to remain in the service of the

    -4-

Company or any Affiliate, and the Participant shall remain subject to discharge to the same extent as if the Plan had never been adopted or the Award had never been made.

2.6. Data Protection Waiver. Participant understands and agrees that in order to process and administer the Award and the Plan, the Company and the Administrator may process personal data and/or sensitive personal information concerning the Participant. Such data and information includes, but is not limited to, the information provided in the Award grant package and any changes thereto, other appropriate personal and financial data about Participant, and information about Participant’s participation in the Plan and transactions under the Plan from time to time. Participant hereby gives his or her explicit consent to the Company and the Administrator to process any such personal data and/or sensitive personal information. Participant also hereby gives his or her explicit consent to the Company and the Administrator to transfer any such personal data and/or sensitive personal data outside the country in which Participant works, is employed or provides services and to the United States. The legal persons granted access to such Participant personal data are intended to include the Company, the Administrator, the outside plan administrator as selected by the Company from time to time, and any other compensation consultant or person that the Company or the Administrator may deem appropriate for the administration of the Plan or the Award. Participant has been informed of his or her right of access and correction to Participant’s personal data by contacting the Company. Participant also understands that the transfer of the information outlined herein is important to the administration of the Award and the Plan and failure to consent to the transmission of such information may limit or prohibit Participant’s participation under the Plan and/or void the Award.

2.7. Savings Clause. In the event that Participant is employed or provides services in a jurisdiction where the performance of any term or provision of this Agreement by the Company: (i) will result in a breach or violation of any statute, law, ordinance, regulation, rule, judgment, decree, order or statement of public policy of any court or governmental agency, board, bureau, body, department or authority, or (ii) will result in the creation or imposition of any penalty, charge, restriction, or material adverse effect upon the Company or an Affiliate, then any such term or provision shall be null, void and of no effect.

2.8. Amendment. The Company may amend the provisions of this Agreement at any time; provided that an amendment that would materially adversely affect the Participant’s rights under this Agreement shall be subject to the written consent of the Participant. No course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

2.9. Acts of Misconduct. If Participant has allegedly committed an act of serious misconduct, including, but not limited to, embezzlement, fraud, dishonesty, unauthorized disclosure of trade secrets or confidential information, breach of fiduciary duty or nonpayment of an obligation owed to the Company, an executive officer of the Company may suspend Participant’s rights under the Award, including the vesting of the Award and the settlement of vested RSUs, subject to the Administrator’s final decision regarding termination of the

    -5-

award. No rights under the Award may be exercised during such suspension or after such termination.

2.10. Disputes. The Administrator or its delegate shall finally and conclusively determine any disagreement concerning the Award.

2.11. Plan. The terms and provisions of the Plan are incorporated herein by reference, a copy of which has been provided or made available to the Participant. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this Agreement, the Plan shall govern and control.

2.12. Compliance with Section 409A of the Code. Notwithstanding any other provision of the Plan or this Agreement to the contrary, the Plan and this Agreement shall be construed or deemed to be amended as necessary to remain exempt from or comply with the requirements of Section 409A of the Code and to avoid the imposition of any additional or accelerated taxes or other penalties under Section 409A of the Code. The Committee, in its sole discretion, shall determine the requirements of Section 409A of the Code applicable to the Plan and this Agreement and shall interpret the terms of each consistently therewith. Under no circumstances, however, shall the Company, an Affiliate, or a subsidiary have any liability under the Plan or this Agreement for any taxes, penalties, or interest due on amounts paid or payable pursuant to the Plan and/or this Agreement, including any taxes, penalties, or interest imposed under Section 409A of the Code. In the event that it is determined by the Company that, as a result of the deferred compensation tax rules under Section 409A of the Code (and any related regulations or other pronouncements thereunder) (the “Deferred Compensation Tax Rules”), benefits that the Participant is entitled to receive under the terms of this Agreement are deferred compensation subject to tax under the Deferred Compensation Tax Rules, (i) the Participant shall not be considered to have terminated employment for purposes hereof until the Participant would be considered to have incurred a “separation from service” within the meaning of the Deferred Compensation Tax Rules and (ii) the Company shall, in lieu of providing such benefit when otherwise due under this Agreement, instead provide such benefit on the first day on which such provision would not result in the Participant incurring any tax liability under the Deferred Compensation Tax Rules; which day, if the Participant is a “specified employee” (within the meaning of the Deferred Compensation Tax Rules), shall, in the event the benefit to be provided is due to the Participant’s “separation from service” (within the meaning of the Deferred Compensation Tax Rules) with the Company and its subsidiaries, be the first day following the six-month period beginning on the date of such separation from service. Each amount to be paid or benefit to be provided under this Agreement shall be construed as a separately identified payment for purposes of the Deferred Compensation Tax Rules, and any payments described in this Agreement that are due within the “short term deferral period” as defined in the Deferred Compensation Tax Rules shall not be treated as deferred compensation unless applicable law requires otherwise.

    -6-

2.13. Successors. The terms of this Agreement shall be binding upon and inure to the benefit of the Company, its successors and assigns, and the Participant and the beneficiaries, executors, administrators, heirs and successors of the Participant.

2.14. Entire Agreement. This Agreement and the Plan contain the entire agreement and understanding of the parties hereto with respect to the subject matter contained herein and supersede all prior communications, representations and negotiations in respect thereof; provided, however, that to the extent that the Participant has entered into an employment agreement, severance agreement or change in control termination agreement with the Company that provides for vesting terms that are more favorable than the vesting terms set forth in this Agreement or the Plan, such more favorable vesting terms shall apply.

2.15 Claw Back Policy. This grant is subject to the terms of the Company’s Claw Back Policy, as it may be amended, modified, superseded or replaced from time to time.

2021 Performance-Based RSU Award Agreement

(2020 Stock Plan)

    In consideration of services rendered to Entegris, Inc. (the “Company”), the Company may periodically make equity incentive awards consisting of performance-based restricted stock units with respect to the Company’s Common Stock, $0.01 par value (“Stock”), to certain key employees, non-employee directors, consultants or advisors of the Company under the Company’s 2020 Stock Plan (as amended from time to time, the “Plan”). Any key employee, non-employee director, consultant or advisor (a “Participant”) who receives a performance-based restricted stock unit award (the “Award”) is notified in writing or via email and the Award is credited to the Participant’s account and reflected under the Stock Plans section on Fidelity’s NetBenefits website. To Accept the award; click on the “Begin your grant acceptance now” link located in the New Grant Alert notification or scroll down to and expand the Stock Plans section; then click on “Begin Acceptance” and follow the prompts. By accepting the Award, Participant: (i) acknowledges that Participant has received a copy of the Plan, of the related prospectus providing information concerning awards under the Plan and of the Company’s most recent Annual Report on Form 10-K; and (ii) accepts the Award and agrees with the Company that the Award is subject to the terms of the Plan and to the following terms and conditions:

Article I – PERFORMANCE-BASED RESTRICTED STOCK UNIT AWARD

1.1. Award Date. This Agreement shall take effect as of the date specified as the Award Date with respect to the Award in the Award summary provided to you online through the Portal (the “Award Date”).

1.2. Performance-basedRestricted Stock Units Subject to Award. The Award consists of that number of performance-based restricted stock units (the “PRSU”) with respect to the Stock that has been approved for the Award to Participant by the Administrator as the target number of PRSUs (“Target PRSUs”). The Target PRSUs shall be subject to increase or decrease in accordance with Sections 1.3 and 1.4 below. Each PRSU is equivalent to one share of the Stock (subject to adjustment under the Plan). The Participant’s rights to the PRSU are subject to the restrictions described in this Agreement and in the Plan (which is incorporated herein by reference with the same effect as if set forth herein in full) in addition to such other restrictions, if any, as may be imposed by law.

1.3. Earned Performance-based Restricted Stock Units. The number of PRSUs earned under this Agreement (the “Earned PRSUs”) shall be equal to the Target PRSUs multiplied by the TSR Performance Multiplier (as defined herein). The “TSR Performance Multiplier” will be determined by comparing the Company’s total stockholder return to the total stockholder return of each of the companies in the Comparator Peer Group (as set forth below) over the period commencing on the Award Date and ending on the third anniversary of the Award Date (the “Performance Period”) to determine the Company’s TSR ranking against the Comparator Group. For purposes of computing total stockholder return: (i), any dividends paid by the Company or the companies in the

Comparator Group shall be treated as having been reinvested at the closing price as of the ex-dividend date; and (ii) the beginning stock price will be the average stock price over the 20 trading days ending on the Award Date and the ending stock price will be the average stock price over the 20 trading days ending on the last day of the Performance Period (adjusted, as applicable, for stock splits, reorganizations, recapitalizations, or similar corporate transactions during such period).

1.4. Calculation of the TSR Performance Multiplier. The TSR Performance Multiplier will be calculated as set forth in the following table based upon the Company’s total stockholder return over the Performance Period when ranked against the total stockholder return over the Performance Period of each of the companies in the Comparator Peer Group:

Company TSR Percentile Rank	TSR Performance Multiplier
Below 25th percentile	0
25th percentile	50%
50th percentile	100%
85th percentile or above	200%

If the Company’s total stockholder return percentile rank during the Performance Period is between the 25th and the 50th percentiles or between the 50th and the 85th percentiles, the TSR Performance Multiplier will be determined using straight line interpolation based on the actual percentile ranking.

As used herein, the “Comparator Peer Group” consists of those companies that are in the Philadelphia Semiconductor Index on the Award Date; provided that, except as provided below, the common stock (or similar equity security) of each such peer company is continually listed or traded on a national securities exchange from the first day of the Performance Period through the last trading day of the Performance Period. In the event a member of the Comparator Peer Group files for bankruptcy or liquidates due to an insolvency or is delisted due to failure to meet the national securities exchange’s minimum market capitalization requirement, such company shall continue to be treated as a Comparator Peer Group member, and such company’s ending price will be treated as $0 if the common stock (or similar equity security) of such company is no longer listed or traded on a national securities exchange on the last trading day of the Performance Period (and if multiple members of the Comparator Peer Group file for bankruptcy or liquidate due to an insolvency or are delisted for such reason, such members shall be ranked in order of when such bankruptcy or liquidation occurs, with earlier bankruptcies, liquidations or delistings ranking lower than later bankruptcies, liquidations or delistings). In the event of a formation of a new parent company by a Comparator Peer Group member, substantially all of the assets and liabilities of which consist immediately after the transaction of the equity interests in the original Comparator Peer Group member or the assets and liabilities of such Comparator Peer Group member immediately prior to the transaction, such new parent company shall be substituted for the Comparator Peer Group member to the extent (and for such period of time) as its common stock (or

    -2-

similar equity securities) are listed or traded on a national securities exchange but the common stock (or similar equity securities) of the original Comparator Peer Group member are not. In the event of a merger or other business combination of two Comparator Peer Group members (including, without limitation, the acquisition of one Comparator Peer Group member, or all or substantially all of its assets, by another Comparator Peer Group member), the surviving, resulting or successor entity, as the case may be, shall continue to be treated as a member of the Comparator Peer Group, provided that the common stock (or similar equity security) of such entity is listed or traded on a national securities exchange through the last trading day of the Performance Period. With respect to the preceding two sentences, the applicable stock prices shall be equitably and proportionately adjusted to the extent (if any) necessary to preserve the intended incentives of the awards and mitigate the impact of the transaction.

The Award shall be subject to limitation that, if the Company’s absolute total shareholder return is negative, then the maximum number of shares that may be earned is the Target PRSUs.

1.5. Vesting of PRSUs. The term “vest” as used herein with respect to any PRSU means the lapsing of the restrictions described herein with respect to such PRSU. The Award shall not be vested as of the Award Date and shall be forfeitable by the Participant without consideration or compensation in accordance with Section 1.6 below unless and until otherwise vested pursuant to the terms of this Agreement. The Participant has no rights, partial or otherwise, in the Award and/or any Stock subject thereto unless and until the Award has been earned pursuant to Section 1.3 and vested pursuant to this Section 1.5.A number of PRSUs equal to the Earned PRSUs will become 100% vested (referred to as “Vested Units”) on the last day of the Performance Period (the “Maturity Date”), provided that the Participant remains continuously employed by the Company or an Affiliate through the Maturity Date. Each Vested Unit shall be settled by the delivery of one share of Stock (subject to adjustment under the Plan). Subject to Section 2.3 below, settlement will occur as soon as practicable following certification by the Administrator of the number of Earned PRSUs and passage of the Maturity Date (or, if earlier, the date the Award becomes vested pursuant to the terms of Section 1.7 below), but in no event later than the earlier of (i) 90 days following the Maturity Date (or such earlier date that the Award becomes vested), or (ii) March 15th of the year following the year in which the Award becomes vested. No fractional shares of Stock shall be issued pursuant to this Agreement.

1.6. Forfeiture Risk. Subject to Section 1.7, If the Participant ceases to be employed or retained by the Company or an Affiliate for any reason, any then-outstanding PRSU that is not a Vested Unit acquired by the Participant hereunder shall be automatically and immediately forfeited. The Participant hereby appoints the Company as the attorney-in-fact of the Participant to take such actions as may be necessary or appropriate to effectuate the cancellation of a forfeited PRSU.

1.7. Early Vesting of PRSUs. This Section sets forth the exclusive circumstances under which the Participant may become entitled to Vested Units even though he or she is not employed through the Maturity Date: (i) If, prior to a Change in Control, the Participant dies, incurs a total and permanent disability (as that term is defined in the Company’s disability insurance policy in effect on the Award Date), or terminates employment on account of retirement from employment with the Company or an Affiliate at age 65 with ten consecutive years of employment with the Company or an Affiliate, prior to the Maturity Date, he or she shall continue to be entitled to receive the Earned PRSUs hereunder, to the extent earned as of the earlier of the Maturity Date and the date of a Change in Control, but the amount otherwise payable shall be prorated to reflect the portion of the Performance Period during which the Participant was employed. (ii) In the event of a Change in Control where the Award is not continued or assumed by a public company, the Earned PRSU, to the extent earned pursuant to the next sentence, shall be fully vested immediately prior to the Change in Control. The number of Earned PRSUs at the time of a Change in Control shall be determined as of the date such Change in Control is consummated, rather than the Maturity Date (as defined in Section 1.5), with the number of Earned PRSUs determined as set forth in Section 1.4 above, based upon the Company’s total stockholder return and the total stockholder return of each of the companies in the Comparator Peer Group through the date of the Change in Control (and, with respect to the Company, instead of the 20-business day average, taking into account the consideration per share to be paid in the Change in Control transaction). (iii) In the event of a Change in Control where the Award is continued or assumed by a public company, then payment of the Earned PRSUs calculated in accordance with clause (ii) above, shall continue to be contingent on the Participant’s employment through the Maturity Date unless there is a Qualifying Termination within two years following the Change in Control. If a Qualifying Termination occurs, the restrictions on all unvested Earned PRSUs shall immediately lapse. The provisions of clauses (ii) and (iii) shall govern the Award notwithstanding the provisions of any Executive Change In Control Termination Agreement (or similar agreement) that may exist between the Company or an Affiliate and the Participant. The distribution of any Vested Units occurring by reason of this Section 1.7 shall be settled by the delivery of one share of Stock (subject to adjustment under the Plan) per Vested Unit. Settlement will occur as soon as practicable following the date the Award becomes vested pursuant to the terms of this Section 1.7, but in no event later than the earlier of (A) 90 days following the date the Award becomes vested, and (B) March 15th of the year following the year in which the Award becomes vested. No fractional shares of Stock shall be issued pursuant to this Agreement.

1.8. Nontransferability of PRSUs. The PRSU acquired by the Participant pursuant to this Agreement shall not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of except as provided below and in the Plan.

1.9. Dividends Equivalent Rights. The Participant shall not be entitled: (i) to receive any dividends or other distributions paid with respect to the Stock to which the PRSU relates, or (ii) to vote any Stock with respect to which the PRSU relates, unless and until, and

    -4-

only to the extent, the PRSU becomes vested and the Participant becomes a stockholder of record with respect to such shares of Stock. Notwithstanding the foregoing, as of each date on which the Company pays an ordinary cash dividend to record owners of shares of Stock, the Participant’s account shall, as of each such dividend date, be credited with a cash amount (without interest) equal to the product of the total number of shares subject to the Target PRSU immediately prior to such dividend date multiplied by the dollar amount of the cash dividend paid per share of Stock by the Company on such dividend date (such amount, the “Dividend Equivalent Amount”). The Dividend Equivalent Amount, which shall be adjusted to reflect the number of Earned PRSUs, shall be subject to the same vesting conditions and settlement terms as the PRSU shares to which they relate.

1.10. Sale of Vested Shares. The Participant understands that Participant will be free to sell any Stock with respect to which the PRSU relates once the PRSU has vested and settled, subject to (i) satisfaction of any applicable tax withholding requirements with respect to the vesting of such PRSU; (ii) the completion of any administrative steps (for example, but without limitation, the transfer of certificates) that the Company may reasonably impose; and (iii) applicable requirements of federal and state securities laws.

1.11. Certain Tax Matters. The Participant expressly acknowledges that the award or vesting of the PRSU acquired hereunder may give rise to income subject to withholding. The Participant expressly acknowledges and agrees that Participant’s rights hereunder are subject to Participant promptly paying to the Company all taxes required to be withheld in connection with such award, vesting, settlement and/or payment. Unless the Administrator determines otherwise, such payment of Participant’s withholding tax obligations shall be made through net share settlement procedures whereby that number of the vesting shares needed to cover the withholding tax obligation (calculated using the Fair Market Value of the Company’s stock on the date of vesting) shall be cancelled to fund the Company’s payment of the withholding tax obligation and the net shares remaining after such cancellation shall be credited to Participant’s account.

1.12 Equitable Adjustments. The Award is subject to adjustment pursuant to Section 15.1 of the Plan.

Article II – GENERAL PROVISIONS

2.1. Definitions. Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan. The following terms shall have the indicated meanings:

“Cause” means (a) “Cause” as defined in any individual agreement to which the Participant and the Company or an Affiliate are parties or (b) if there is no such agreement or if it does not define Cause, the Company's termination of the Participant’s employment with the Company or any Affiliate following the occurrence of any one or more of the following: (i) the Participant’s conviction of, or plea of guilty or nolo contendere to, a felony; (ii) the Participant’s willful and continual failure to substantially perform the Participant’s duties after written notification by the Company; (iii) the

    -5-

Participant’s willful engagement in conduct that is materially injurious to the Company or an Affiliate monetarily or otherwise; (iv) the Participant’s commission of an act of gross misconduct in connection with the performance of the Participant’s duties; (v) the Participant’s material breach of any employment, confidentiality, or other similar agreement between the Company or an Affiliate and the Participant; or (vi) prior to a Change in Control, such other events as shall be determined by the Administrator.

“Qualifying Termination” means the termination of a Participant’s employment with the Company or an Affiliate (a) by the Company for any reason other than Cause, death, or total and permanent disability (as that term is defined in the Company’s disability insurance policy in effect on the Award Date); or (b) by the Participant because of the occurrence, without the Participant’s consent, of (i) a material reduction in the position, duties, or responsibilities of the Participant from those in effect immediately prior to such change; (ii) a reduction in the Participant’s base salary; (iii) a relocation of the Participant’s primary work location to a distance of more than 50 miles from its location as of immediately prior to such change; or (iv) a material breach by the Company or an Affiliate of any employment agreement with the Participant. In order to invoke a termination of employment pursuant to clause (b) of this definition, Participant shall provide written notice to the Company of the existence of one or more of the conditions described in clauses (i) through (iv) within 90 days following the Participant’s knowledge of the initial existence of such condition or conditions, and the Company shall have 30 days following receipt of such written notice (the “Cure Period”) during which it may remedy the condition(s). In the event that the Company fails to remedy the condition(s) covered by clause (b) of this definition during the Cure Period, the Participant must terminate employment, if at all, within 90 days following the Cure Period in order for such termination of employment to constitute a Qualifying Termination.

2.2. No Understandings as to Employment etc. The Participant further expressly acknowledges that nothing in the Plan or any modification thereto, in the Award or in this Agreement shall constitute or be evidence of any understanding, express or implied, on the part of the Company to employ or retain the Participant for any period or with respect to the terms of the Participant’s employment or to give rise to any right to remain in the service of the Company or any Affiliate, and the Participant shall remain subject to discharge to the same extent as if the Plan had never been adopted or the Award had never been made.

2.3.    Compliance with Section 409A of the Code. Notwithstanding any other provision of the Plan or this Agreement to the contrary, the Plan and this Agreement shall be construed or deemed to be amended as necessary to remain exempt from or comply with the requirements of Section 409A of the Code and to avoid the imposition of any additional or accelerated taxes or other penalties under Section 409A of the Code. The Committee, in its sole discretion, shall determine the requirements of Section 409A of the Code applicable to the Plan and this Agreement and shall interpret the terms of each consistently therewith. Under no circumstances, however, shall the Company, an Affiliate, or a subsidiary have any liability under the Plan or this Agreement for any

    -6-

taxes, penalties, or interest due on amounts paid or payable pursuant to the Plan and/or this Agreement, including any taxes, penalties, or interest imposed under Section 409A of the Code. In the event that it is determined by the Company that, as a result of the deferred compensation tax rules under Section 409A of the Code (and any related regulations or other pronouncements thereunder) (the “Deferred Compensation Tax Rules”), benefits that the Participant is entitled to receive under the terms of this Agreement are deferred compensation subject to tax under the Deferred Compensation Tax Rules, (i) the Participant shall not be considered to have terminated employment for purposes hereof until the Participant would be considered to have incurred a “separation from service” within the meaning of the Deferred Compensation Tax Rules and (ii) the Company shall, in lieu of providing such benefit when otherwise due under this Agreement, instead provide such benefit on the first day on which such provision would not result in the Participant incurring any tax liability under the Deferred Compensation Tax Rules; which day, if the Participant is a “specified employee” (within the meaning of the Deferred Compensation Tax Rules), shall, in the event the benefit to be provided is due to the Participant’s “separation from service” (within the meaning of the Deferred Compensation Tax Rules) with the Company and its subsidiaries, be the first day following the six-month period beginning on the date of such separation from service. Each amount to be paid or benefit to be provided under this Agreement shall be construed as a separately identified payment for purposes of the Deferred Compensation Tax Rules, and any payments described in this Agreement that are due within the “short term deferral period” as defined in the Deferred Compensation Tax Rules shall not be treated as deferred compensation unless applicable law requires otherwise.

2.4.    Data Protection Waiver. Participant understands and agrees that in order to process and administer the Award and the Plan, the Company and the Administrator may process personal data and/or sensitive personal information concerning the Participant. Such data and information includes, but is not limited to, the information provided in the Award grant package and any changes thereto, other appropriate personal and financial data about Participant, and information about Participant’s participation in the Plan and transactions under the Plan from time to time. Participant hereby gives his or her explicit consent to the Company and the Administrator to process any such personal data and/or sensitive personal information. Participant also hereby gives his or her explicit consent to the Company and the Administrator to transfer any such personal data and/or sensitive personal data outside the country in which Participant works, is employed or provides services and to the United States. The legal persons granted access to such Participant personal data are intended to include the Company, the Administrator, the outside plan administrator as selected by the Company from time to time, and any other compensation consultant or person that the Company or the Administrator may deem appropriate for the administration of the Plan or the Award. Participant has been informed of his or her right of access and correction to Participant’s personal data by contacting the Company. Participant also understands that the transfer of the information outlined herein is important to the administration of the Award and the Plan and failure to consent to the transmission of such information may limit or prohibit Participant’s participation under the Plan and/or void the Award.

    -7-

2.5.    Savings Clause. In the event that Participant is employed or provides services in a jurisdiction where the performance of any term or provision of this Agreement by the Company: (i) will result in a breach or violation of any statute, law, ordinance, regulation, rule, judgment, decree, order or statement of public policy of any court or governmental agency, board, bureau, body, department or authority, or (ii) will result in the creation or imposition of any penalty, charge, restriction, or material adverse effect upon the Company or an Affiliate, then any such term or provision shall be null, void and of no effect.

2.6.    Amendment. The Company may amend the provisions of this Agreement at any time; provided that an amendment that would materially adversely affect the Participant’s rights under this Agreement shall be subject to the written consent of the Participant. No course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

2.7.    Acts of Misconduct. If Participant has allegedly committed an act of serious misconduct, including, but not limited to, embezzlement, fraud, dishonesty, unauthorized disclosure of trade secrets or confidential information, breach of fiduciary duty or nonpayment of an obligation owed to the Company, an executive officer of the Company may suspend Participant’s rights under the Award, including the vesting of the Award and the settlement of vested PRSUs, subject to the Administrator’s final decision regarding termination of the Award. No rights under the Award may be exercised during such suspension or after such termination.

2.8.Disputes. The Administrator or its delegate shall finally and conclusively determine any disagreement concerning the Award.

2.9.    Plan. The terms and provisions of the Plan are incorporated herein by reference, a copy of which has been provided or made available to the Participant. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this Agreement, the Plan shall govern and control.

2.10.    Successors. The terms of this Agreement shall be binding upon and inure to the benefit of the Company, its successors and assigns, and the Participant and the beneficiaries, executors, administrators, heirs and successors of the Participant.

2.11.    Entire Agreement. This Agreement and the Plan contain the entire agreement and understanding of the parties hereto with respect to the subject matter contained herein and supersede all prior communications, representations and negotiations in respect thereof; provided, however, that to the extent that the Participant has entered into an employment agreement, severance agreement or change in control termination agreement with the Company that provides for vesting terms that are more favorable than the vesting terms set forth in this Agreement or the Plan, such more favorable vesting terms shall apply.

2.12    Claw Back Policy. This grant is subject to the terms of the Company’s Claw Back Policy, as it may be amended, modified, superseded or replaced from time to time.

The Award consists of that number of restricted stock units (the “RSU”) with respect to the Stock that has been approved for the Award to Participant by the Administrator. Each RSU is equivalent to one share of the Stock. The Participant’s rights to the RSU are subject to the restrictions described in this Agreement and in the Plan (which is incorporated herein by reference with the same effect as if set forth herein in full) in addition to such other restrictions, if any, as may be imposed by law.

1.6. Vesting and Settlement of RSUs. The RSU acquired hereunder shall vest in accordance with the provisions of this Article I, Section 1.6 and applicable provisions of the Plan, as follows:

Upon vesting, each RSU shall entitle Participant to receive one share of Stock (subject to adjustment under the Plan).

Vested RSUs shall be settled in shares of Stock (or, in the discretion of the Administrator, in cash equal to the Fair Market Value thereof). Subject to Section 2.12, settlement and delivery of the applicable number of shares of Stock (or cash equivalent, if applicable) shall be made as soon as practicable following vesting, but in no event later than 30 days after the applicable vesting date. No fractional shares of Stock shall be issued pursuant to this Agreement.

1.7. Dividend Equivalent Rights. The Participant shall not be entitled: (i) to receive any dividends or other distributions paid with respect to the Stock to which the RSU relates, or (ii) to vote any Stock with respect to which the RSU relates, unless and until, and only to the extent, the RSU becomes vested and the Participant becomes a stockholder of record with respect to such shares of Stock. Notwithstanding the foregoing, as of each date on which the Company pays an ordinary cash dividend to record owners of shares of Stock, the Participant’s account shall, as of each such dividend date, be credited with a cash amount (without interest) equal to the product of the total number of shares subject to the RSU immediately prior to such dividend date multiplied by the dollar amount of the cash dividend paid per share of Stock by the Company on such dividend date (such amount, the “Dividend Equivalent Amount”). The Dividend Equivalent Amount shall be subject to the same vesting conditions and settlement terms as the RSU shares to which they relate.

1.8. Sale of Vested Shares. The Participant understands that Participant will be free to sell any Stock with respect to which the RSU relates once the RSU has vested and settled, subject to (i) satisfaction of any applicable tax withholding requirements with respect to the vesting of such RSU; (ii) the completion of any administrative steps (for example, but without limitation, the transfer of certificates) that the Company may reasonably impose; and (iii) applicable requirements of federal and state securities laws.

            (ii)    Only to the extent consistent with Section 409A of the Code, in the event of a Change in Control in which the successor company assumes or substitutes for the RSU (or in which the Company is the ultimate parent corporation and continues the Award), if Participant’s employment with such successor company (or the Company) or an affiliate thereof is involuntarily terminated without Cause by the successor employer or Participant resigns for Good Reason, in either case within 24 months following such Change in Control: the restrictions, limitations and other conditions applicable to the RSU shall lapse and the RSU shall become free of all restrictions, limitations and conditions and become fully vested.

        (b)    Awards Not Assumed or Substituted. In the event of a Change in Control in which the successor company does not assume or substitute for the RSU (or in which the Company is the ultimate parent corporation and does not continue the Award): the restrictions, limitations and other conditions applicable to the RSU shall lapse and the RSU shall become free of all restrictions, limitations and conditions and become fully vested, provided that if the RSU constitutes nonqualified deferred compensation pursuant to Section 409A, the RSU will not be settled until the earliest to occur of the regularly scheduled vesting date, Participant’s retirement in accordance with Section 2.3 and Participant’s termination without Cause or for Good Reason, subject to application of a six-month delay if the Participant is a specified employee under Section 409A.

        (c)    Good Reason Definition. For purposes of this Section 2.2, “Good Reason” means (i) “Good Reason” as defined in any individual agreement to which Participant and the Company or an Affiliate are parties, or (ii) if there is no such agreement or if it does not

In the event that the Company fails to remedy the condition(s) constituting Good Reason during the Cure Period, the Participant must terminate employment, if at all, within 90 days following the Cure Period in order for such termination to constitute a termination of employment for Good Reason.

    (d)    Cause Definition. “Cause” means (i) “Cause” as defined in any individual agreement to which the Participant and the Company or an Affiliate are parties or (ii) if there is no such agreement or if it does not define Cause, the Company’s termination of the Participant’s employment with the Company or any Affiliate following the occurrence of any one or more of the following: (A) the Participant’s conviction of, or plea of guilty or nolo contendere to, a felony; (B) the Participant’s willful and continual failure to substantially perform the Participant’s duties after written notification by the Company; (C) the Participant’s willful engagement in conduct that is materially injurious to the Company or an Affiliate monetarily or otherwise; (D) the Participant’s commission of an act of gross misconduct in connection with the performance of the Participant’s duties; or (E) the Participant’s material breach of any employment, confidentiality, or other similar agreement between the Company or an Affiliates and the Participant.

As used herein the term “retirement with the consent of the Administrator” means that Participant’s retirement must be with the consent of the Administrator, which consent may be granted or withheld in the discretion of the Administrator. In the event that Participant ceases to be an employee under circumstances that would otherwise qualify for retirement but the consent of the Administrator has not been granted, then Participant shall not be entitled to the benefits of this Section 2.3.

2.4. Equitable Adjustments. The Award is subject to adjustment pursuant to Section 15.1 of the Plan.

    -4-

Company or any Affiliate, and the Participant shall remain subject to discharge to the same extent as if the Plan had never been adopted or the Award had never been made.

2.8. Amendment. The Company may amend the provisions of this Agreement at any time; provided that an amendment that would materially adversely affect the Participant’s rights under this Agreement shall be subject to the written consent of the Participant.

Each amount to be paid or benefit to be provided under this Agreement shall be construed as a separately identified payment for purposes of the Deferred Compensation Tax Rules, and any payments described in this Agreement that are due within the “short term deferral period” as defined in the Deferred Compensation Tax Rules shall not be treated as deferred compensation unless applicable law requires otherwise.

The shares of Stock awarded are specified in the Stock Options Plan section in the Granted column online through Fidelity’s NetBenefits website. The Option is not intended to be an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended, and will be interpreted accordingly.

1.2. Option Exercise Price. The exercise (grant) price of the Option shall be 100% of the closing price of the Stock on the NASDAQ stock market on the Grant Date. The exercise price is provided to Participant online through Fidelity’s NetBenefits website.

1.3. Option Vesting Schedule. This Option shall vest and become exercisable, except as hereinafter provided, in whole or in part, as follows:

•25% on ________, 2022;

•an additional 25% on _________, 2023;

•an additional 25% on ________, 2024;

•the final 25% on ________, 2025.

1.4. Expiration of Option. To the extent that the Option shall not have been exercised, this Option shall expire at 5:00 p.m. local time at the Company’s headquarters on ________, _____ and no part of the Option may be exercised thereafter. If an expiration, termination or forfeiture date described herein falls on a weekday, Participant must exercise the Option before 5:00 p.m. local time at the Company’s headquarters on that date. If an expiration, termination or forfeiture date described herein falls on a weekend or any other day on which the NASDAQ stock market is not open, Participant must exercise the Option before

5:00 p.m. local time at the Company’s headquarters on the last NASDAQ business day prior to the expiration, termination or forfeiture date.

1.5. Exercise of Option. When and as vested, this Option may be exercised up to the number of shares of Stock specified in Section 1.1 above only by serving written notice on the designated stock plan administrator. Payment of the Option exercise price specified in Section 1.2 above may be made (i) in cash or by certified check, (ii) through net share settlement procedures whereby that number of the Option shares being exercised that are needed to cover the payment of the Option exercise price (calculated using the Fair Market Value of the Company’s stock on the date of exercise) shall be cancelled to fund the payment of the Option exercise price, (iii) by broker assisted sale of shares to satisfy the Option exercise price; or (iv) by any other method specified in the Plan or as permitted by the Administrator. No fractional shares of Stock shall be issued pursuant to this Agreement. Participant will have the rights of a stockholder only after the shares of Stock have been issued to the Participant in accordance with this Agreement.

1.6. No Assignment of Option. This Option may not be assigned or transferred except as may otherwise be provided by the terms of this Agreement.

1.7. Equitable Adjustments. The Award is subject to adjustment pursuant to Section 15.1 of the Plan.

1.8. Termination of Employment or Service with the Company. All exercisable Options granted herein must be exercised within ninety (90) days following the date on which the employment or services of Participant with the Company or an Affiliate terminates (i.e., last day worked, excluding any severance period), or, if earlier, prior to the original expiration date of the Option (“Termination Date”), or be forfeited, except as provided in Sections 2.2 and 2.3 below and as follows:

(a)    In the event of Participant’s death during employment/services, each Option granted hereunder will be exercisable, whether or not vested on or prior to the date of Participant’s death, until the earlier of: (1) the first anniversary of Participant’s date of death; or (2) the original expiration date of the Option. In the event of Participant’s death during a Special Exercise Period as specified in Section 2.3 below, each Option will continue to be exercisable in accordance with the provisions of that Section.

(b)    In the event of the termination of employment/services of Participant due to Disability, Participant may exercise the Option, whether or not vested on or prior to the date of employment or service termination, at any time prior to the earlier of the original expiration date of the Option and 365 days following the later of the date of Participant’s separation from service due to Participant’s Disability or the date of determination of Participant’s Disability, provided, however, that while the claim of Disability is pending, Options that were unvested at termination of services may not be exercised and Options that were vested at termination of services may be exercised only during the period set forth in the introductory clause to this Section 1.8. The Option shall terminate on the earlier of the original expiration date of the Option and 365 days following the later of the date of Participant’s separation from

-2-

service due to Participant’s Disability or the date of determination of Participant’s Disability, to the extent that it is unexercised. For these purposes “Disability” shall be determined in accordance with the standards and procedures of the then-current Long-Term Disability policies maintained by the Company, which is generally a physical condition arising from an illness or injury which renders an individual incapable of performing work in any occupation, as determined by the Company.

(c)    If Participant’s employment/services is terminated for “Cause”, all granted but unexercised stock Options, whether vested or unvested, shall be forfeited on Participant’s Termination Date.

1.9. Suspension of Option Exercises. For administrative or other reasons, the Company may, from time to time, suspend the ability of Participants to exercise options for limited periods of time. Notwithstanding the above, the Company shall not be obligated to deliver any shares of Stock during any period when the Company determines that the exercisability of the Option or the delivery of shares hereunder would violate any federal, state or other applicable laws.

1.10. Withholding of Income Taxes. The Company shall have no obligation to issue shares upon exercise of this Option unless the Participant has satisfied any tax withholding obligation with respect to such exercise. Payment of Participant’s withholding tax obligations may be made through any method specified in the Plan or as permitted by the Administrator.

Article II – GENERAL PROVISIONS

2.1. Definitions. Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan.

2.2. Change in Control.

        (a)    Assumption or Substitution.

            (i)     If the Change in Control is one in which there is an acquiring or surviving entity, the Administrator may provide for the assumption or continuation of some or all outstanding Awards or for the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor.

            (ii)    In the event of a Change in Control in which the successor company assumes or substitutes for the Option (or in which the Company is the ultimate parent corporation and continues the Award), if Participant’s employment with such successor company (or the Company) or an affiliate thereof is involuntarily terminated without Cause by the successor employer or Participant resigns for Good Reason, in either case within 24 months following such Change in Control: the Option will immediately vest, become fully exercisable, and may thereafter be exercised for 24 months (but in no event after the original expiration date specified in Section 1.4 above). For the purposes of this Section 2.2, the Option shall be considered assumed or substituted for if following the Change in Control the Award confers the right to purchase or receive, for each share of Stock subject to the Option immediately prior to the Change in Control, the consideration (whether stock, cash or other securities or property) received in the transaction

-3-

constituting a Change in Control by holders of Stock for each Share held on the effective date of such transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Stock); provided, however, that if such consideration received in the transaction constituting a Change in Control is not solely common stock of the successor company, the Administrator may, with the consent of the successor company, provide that the consideration to be received upon the exercise or vesting of the Option, for each Share subject thereto, will be solely common stock of the successor company substantially equal in fair market value to the per Share consideration received by holders of Stock in the transaction constituting a Change in Control. The determination of such substantial equality of value of consideration shall be made by the Administrator in its sole discretion and its determination shall be conclusive and binding.

        (b)    Awards Not Assumed or Substituted. In the event of a Change in Control in which the successor company does not assume or substitute for the Option (or in which the Company is the ultimate parent corporation and does not continue the Award): the Option shall immediately vest and become fully exercisable.

        (c)    Good Reason Definition. For purposes of this Section 2.2, “Good Reason” means (i) “Good Reason” as defined in any individual agreement to which Participant and the Company or an Affiliate are parties, or (ii) if there is no such agreement or if it does not define Good Reason, without the Participant’s prior written consent: (A) a reduction in the Participant’s base salary; (B) a relocation of the Participant’s primary work location to a distance of more than 50 miles from its location as of immediately prior to such change; or (C) a material breach by the Company or an Affiliate of any employment agreement with the Participant. In order to invoke a termination of employment for Good Reason, a Participant shall provide written notice to the Company of the existence of one or more of the conditions described in clauses (A) through (C) within 90 days following the Participant’s knowledge of the initial existence of such condition or conditions, and the Company shall have 30 days following receipt of such written notice (the “Cure Period”) during which it may remedy the condition(s). In the event that the Company fails to remedy the condition(s) constituting Good Reason during the Cure Period, the Participant must terminate employment, if at all, within 90 days following the Cure Period in order for such termination to constitute a termination of employment for Good Reason.

    (d)    Cause Definition. “Cause” means (i) “Cause” as defined in any individual agreement to which the Participant and the Company or an Affiliate are parties or (ii) if there is no such agreement or if it does not define Cause, the Company’s termination of the Participant’s employment with the Company or any Affiliate following the occurrence of any one or more of the following: (A) the Participant’s conviction of, or plea of guilty or nolo contendere to, a felony; (B) the Participant’s willful and continual failure to substantially perform the Participant’s duties after written notification by the Company; (C) the Participant’s willful engagement in conduct that is materially injurious to the Company or an Affiliate monetarily or otherwise; (D) the Participant’s commission of an act of gross misconduct in connection with the performance of the Participant’s duties; or (E) the Participant’s material breach of any employment, confidentiality, or other similar agreement between the Company or an Affiliate and the Participant.

-4-

2.3. Retirement. If Participant is an employee of the Company or an Affiliate and ceases to be an employee due to retirement with the consent of the Administrator, Participant will be entitled to a special exercise period with respect to the Option (the “Special Exercise Period”) which will begin on Participant’s retirement date and will end on the earlier of the 4th anniversary of Participant’s retirement date or the expiration date specified in Section 1.4 above. During the Special Exercise Period, the Option will continue to vest in accordance with the schedule specified in Section 1.3 above and will be exercisable to the same extent that it would have been exercisable had Participant remained in service with the Company or an Affiliate. As used herein the term “retirement with the consent of the Administrator” means that Participant’s retirement must be with the consent of the Administrator, which consent may be granted or withheld in the discretion of the Administrator. In the event that Participant ceases to be an employee under circumstances that would otherwise qualify for retirement but the consent of the Administrator has not been granted, then Participant shall not be entitled to the benefits of this Section 2.3.

2.4. No Understandings as to Employment, etc. The Participant further expressly acknowledges that nothing in the Plan or any modification thereto, in the Award or in this Agreement shall constitute or be evidence of any understanding, express or implied, on the part of the Company to employ or retain the Participant for any period or with respect to the terms of the Participant’s employment or to give rise to any right to remain in the service of the Company or any Affiliate, and the Participant shall remain subject to discharge to the same extent as if the Plan had never been adopted or the Award had never been made.

2.5. Acts of Misconduct. If Participant has allegedly committed an act of serious misconduct, including, but not limited to, embezzlement, fraud, dishonesty, unauthorized disclosure of trade secrets or confidential information, breach of fiduciary duty or nonpayment of an obligation owed to the Company, an Executive Officer of the Company may suspend Participant’s rights under the Award, including the vesting of Options and the exercise of vested Options, subject to the Administrator’s final decision regarding termination of the award. No rights under the Award may be exercised during such suspension or after such termination.

2.6. Data Protection Waiver. Participant understands and agrees that in order to process and administer the Award and the Plan, the Company and the Administrator may process personal data and/or sensitive personal information concerning the Participant. Such data and information includes, but is not limited to, the information provided in the Award grant package and any changes thereto, other appropriate personal and financial data about Participant, and information about Participant’s participation in the Plan and transactions under the Plan from time to time. Participant hereby gives his or her explicit consent to the Company and the Administrator to process any such personal data and/or sensitive personal information. Participant also hereby gives his or her explicit consent to the Company and the Administrator to transfer any such personal data and/or sensitive personal data outside the country in which Participant works, is employed or provides services and to the United States. The legal persons granted access to such Participant personal data are intended to include the Company, the Administrator, the outside plan administrator as selected by the Company from time to time, and any other compensation consultant or person that the Company or the Administrator may deem appropriate for the

-5-

administration of the Plan or the Award. Participant has been informed of his or her right of access and correction to Participant’s personal data by contacting the Company. Participant also understands that the transfer of the information outlined herein is important to the administration of the Award and the Plan and failure to consent to the transmission of such information may limit or prohibit Participant’s participation under the Plan and/or void the Award.

2.7. Disputes. The Administrator or its delegate shall finally and conclusively determine any disagreement concerning the Award.

2.8. Savings Clause. In the event that Participant is employed or provides services in a jurisdiction where the performance of any term or provision of this Agreement by the Company: (i) will result in a breach or violation of any statute, law, ordinance, regulation, rule, judgment, decree, order or statement of public policy of any court or governmental agency, board, bureau, body, department or authority, or (ii) will result in the creation or imposition of any penalty, charge, restriction, or material adverse effect upon the Company or an Affiliate, then any such term or provision shall be null, void and of no effect.

2.9. Amendment. The Company may amend the provisions of this Agreement at any time; provided that an amendment that would materially adversely affect the Participant’s rights under this Agreement shall be subject to the written consent of the Participant. No course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

2.10.Plan. The terms and provisions of the Plan are incorporated herein by reference, a copy of which has been provided or made available to the Participant. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this Agreement, the Plan shall govern and control.

2.11.Successors. The terms of this Agreement shall be binding upon and inure to the benefit of the Company, its successors and assigns, and the Participant and the beneficiaries, executors, administrators, heirs and successors of the Participant.

2.12.Entire Agreement. This Agreement and the Plan contain the entire agreement and understanding of the parties hereto with respect to the subject matter contained herein and supersede all prior communications, representations and negotiations in respect thereof; provided, however, that to the extent that the Participant has entered into an employment agreement, severance agreement or change in control termination agreement with the Company that provides for vesting and/or exercise terms that are more favorable than the vesting and/or exercise terms set forth in this Agreement or the Plan, such more favorable vesting and/or exercise terms shall apply.

2.13Claw Back Policy. This grant is subject to the terms of the Company’s Claw Back Policy, as it may be amended, modified, superseded or replaced from time to time.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations Entegris, Inc. (Entegris or the Company) 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.

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 Doubtful Accounts 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 doubtful accounts that management believes is adequate to cover expected losses on trade receivables.

Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined by the first-in, first-out (FIFO) method.

Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating leases. Lease liabilities for operating leases are classified in “Other accrued liabilities” and “Long-term lease liabilities” in our consolidated balance sheet. We do not have material financing leases.

Operating assets and liabilities 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 includes prepaid lease payments and excludes 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.

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 on the straight-line method over the estimated useful lives of the assets. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and gains or losses are recognized in the same period. 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).

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.

The fair value of long-term debt, including current maturities, based upon models utilizing market observable (Level 2) inputs and credit risk, was $1,126.6 million at December 31, 2020 compared to the carrying amount of long-term debt, including current maturities, of $1,085.8 million at December 31, 2020.

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. The Company compares the carrying value of its reporting units, including goodwill, to their fair value. For reporting units in which the assessment indicates that it is more likely than not that the fair value is more than its carrying value, goodwill is not considered impaired. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired.

Based on its annual analysis, the Company determined there was no indication of impairment of goodwill and the estimated fair value of each reporting unit substantially exceeded its carrying value.

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 records derivatives as assets or liabilities on the balance sheet and measures such instruments at fair value. Changes in fair value of derivatives are recorded each period in the Company’s consolidated statements of operations.

The Company periodically enters into forward foreign currency contracts to reduce exposures relating to rate changes in certain foreign currencies. Certain exposures to credit losses related to counterparty nonperformance exist. However, the Company does not anticipate nonperformance by the counterparties since they are large, well-established financial institutions. None of these derivatives is accounted for as a hedge transaction. Accordingly, changes in the fair value of forward foreign currency contracts are recorded as other expense (income), net, in the Company’s consolidated statements of operations. The fair values of the Company’s derivative financial instruments are based on prices quoted by financial institutions for these instruments.

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 weighted 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 incurred are recorded in cost of sales in the Company’s consolidated statements of operations.

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.

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 (Loss) Comprehensive income (loss) 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, and minimum pension liability adjustments are included in accumulated other comprehensive loss. Comprehensive income (loss) and the components of accumulated other comprehensive loss are presented in the accompanying consolidated statements of comprehensive income (loss) and consolidated statements of equity.

Recent Accounting Pronouncements Adopted in 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities are required to use a new forward-looking “expected loss” model that replaced the current “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The Company adopted this new guidance in the first quarter of fiscal 2020. The adoption of ASU 2016-13 did not impact the consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The Company adopted this guidance in 2020. The adoption of ASU 2018-14 did not impact the consolidated financial statements.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

REVENUES

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 below.

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

Nature of goods and services The following is a description of principal activities from which the Company generates its revenues. The Company has three reportable segments. For more detailed information about reportable segments, see note 16 to the consolidated financial statements. For each of the three 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.

The Company generally recognizes revenue for sales of services when the Company has satisfied the performance obligation. The payment terms and revenue recognized is 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.

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 below until the performance obligations are satisfied.

The purchase price of GMTI exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $16.1 million. Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets. This additional investment value resulted in goodwill, which is expected to be non-deductible for income tax purposes.

During the quarter ended September 26, 2020, the Company finalized its fair value determination of the assets acquired and the liabilities assumed. The following table summarizes the final allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of the acquisition:

2028 Senior Unsecured Notes

On April 30, 2020, the Company issued $400.0 million aggregate principal amount of 4.375% senior unsecured notes due April 15, 2028 (the “2028 Notes”). The 2028 Notes were issued under an indenture dated as of April 30, 2020 (the “2028 Notes Indenture”) by and among the Company, certain subsidiaries of the Company and Wells Fargo Bank, National Association, as trustee (the “2028 Notes Trustee”). Interest on the 2028 Notes is payable semi-annually in arrears on April 15 and October 15 of each year, commencing on October 15, 2020. The Company incurred debt issuance costs of $4.0 million in connection with the 2028 Notes. These costs are reported in the consolidated balance sheet as a direct deduction from the face amount of the 2028 Notes.

The 2028 Notes are guaranteed, jointly and severally, fully and unconditionally, on a senior unsecured basis, by the Company’s existing and future domestic subsidiaries, other than certain excluded subsidiaries, to the extent that such entities guarantee indebtedness under the Company’s senior secured term loan facility due 2025 and senior secured revolving credit facility due 2023 (together, the “Senior Secured Credit Facilities”) or the Company’s 4.625% senior unsecured notes due 2026 (the “2026 Notes”) and any other subsidiary of the Company to the extent it incurs certain additional indebtedness (collectively, the “Guarantors”).

The 2028 Notes and the guarantees thereof are the Company’s and the Guarantors’ senior unsecured obligations, respectively, and will (i) rank equally in right of payment with all of the Company’s and the Guarantors’ existing and future senior

indebtedness (including the 2026 Notes); (ii) rank senior to any subordinated indebtedness that the Company or the Guarantors may incur; (iii) be effectively subordinated to all of the Company’s or the Guarantors’ existing and future secured indebtedness (including the Senior Secured Credit Facilities), in each case, to the extent of the value of the assets securing such indebtedness; and (iv) be structurally subordinated in right of payment to all existing and future obligations of the Company’s subsidiaries that do not guarantee the 2028 Notes.

At any time prior to April 15, 2023, the Company may, at its option, on any one or more occasions, redeem up to 40% of the aggregate principal amount of the 2028 Notes, at a redemption price equal to 104.375% of the principal amount of the 2028 Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, with an amount of cash equal to the net cash proceeds of an equity offering, as defined in the 2028 Notes Indenture, by the Company; provided that (1) at least 60% of the aggregate principal amount of 2028 Notes issued under the 2028 Notes Indenture remains outstanding immediately after the occurrence of each such redemption; and (2) the redemption occurs within 120 days of the date of the closing of such equity offering.

Additionally, at any time prior to April 15, 2023, the 2028 Notes may be redeemed, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of the 2028 Notes redeemed, plus a “make whole” premium, plus accrued and unpaid interest to, but not including, the applicable redemption date.

On or after April 15, 2023, the Company may on any one or more occasions redeem all or a part of the 2028 Notes, at its option, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the 2028 Notes redeemed, to, but not including, the applicable date of redemption, if redeemed during the 12-month period beginning on April 15 of the years indicated below:

Year	Percentage
2023	102.188	%
2024	101.094	%
2025 and thereafter	100.000	%

Upon the occurrence of certain change of control events accompanied by certain ratings events, the Company will be required to offer to repurchase all of the outstanding 2028 Notes at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

The 2028 Notes Indenture that governs the 2028 Notes contains covenants that, among other things, limit the Company’s ability and/or the ability of the Company’s subsidiaries to incur liens, engage in sale and leaseback transactions and consolidate, merge with or convey, transfer or lease all or substantially all of the Company’s and its subsidiaries’ assets to another person. The 2028 Notes Indenture also, subject to certain exceptions, limits the ability of any non-Guarantor subsidiary of the Company to incur indebtedness. These covenants are subject to a number of other limitations and exceptions as set forth in the 2028 Notes Indenture. The Company is in compliance with all of the above covenants at December 31, 2020.

The 2028 Notes Indenture provides for events of default which, if certain of them occur, would permit the 2028 Notes Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2028 Notes to declare the principal of, and interest or premium, if any, and any other monetary obligations on, all the then-outstanding 2028 Notes to be due and payable immediately.

2026 Senior Unsecured Notes

As provided in the 2026 Notes Indenture, the Company may at its option on one or more occasions redeem all or a part of the 2026 Notes at a redemption price equal to (a) 100% of the principal amount of the 2026 Notes redeemed plus a make-whole premium if redeemed prior to November 10, 2020, or (b) 100% of the principal amount of the 2026 Notes redeemed plus a percentage of principal amount between 100% and 103.469% of the aggregate principal amount of the 2026 Notes to be redeemed, depending on the period of redemption, if redeemed on or after November 10, 2020, plus, in each case, accrued and unpaid interest on the amount of 2026 Notes being redeemed.

Upon a change in control accompanied by certain rating events, the Company is required to offer to repurchase all of the 2026 Notes at a price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

The 2026 Notes Indenture contains covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of the Company’s restricted subsidiaries to create liens, enter into sale and leaseback transactions, engage in consolidations or mergers, or sell, transfer or otherwise dispose of all or substantially all of their assets. The 2026 Notes Indenture also, subject to certain exceptions, limits the ability of any subsidiary of the Company that is not a guarantor under the 2026 Notes to incur indebtedness. The Company is in compliance with all of the above covenants at December 31, 2020.

The 2026 Notes Indenture also provides for events of default which, if certain of them occur, would permit the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2026 Notes to declare the principal, premium, if any, interest and any other monetary obligations on all the then-outstanding 2026 Notes to be due and payable immediately.

Senior Secured Credit Facilities

On November 6, 2018, the Company entered into a credit and guaranty agreement with Goldman Sachs Bank USA, as administrative agent and collateral agent, and added two additional lenders to the lenders party thereto. The credit agreement was amended in October 2019 (as so amended, the “Credit Agreement”) to change the administrative agent and collateral agent to Morgan Stanley and add two lenders. The Credit Agreement provides senior secured financing in an aggregate principal amount of $700 million, consisting initially of (a) term loans in an aggregate principal amount of $400 million (the “New Term Loan Facility”) and (b) revolving commitments in an aggregate amount of $300 million (the “New Revolving Facility”, and together with the New Term Loan Facility, the “New Credit Facilities”). Borrowings under the New Credit Facilities bear interest at a rate per annum equal to, at the Company’s option, a base rate (such as prime rate or LIBOR) plus an applicable margin. The Company’s interest rate on the term loans under the New Term Loan Facility is 2.15% at December 31, 2020. In addition to paying interest on the outstanding principal under the New Credit Facilities, the Company will pay (i) with respect to the New Term Loan Facility, customary agency fees, and (ii) with respect to the New Revolving Facility, a commitment fee in respect of the unutilized commitments thereunder and customary letter of credit fees and agency fees. The initial commitment fee is 0.20% per annum.

Debt issuance costs of $5.1 million for the year ended December 31, 2018 were paid to third parties and are capitalized as debt issuance costs in connection with the New Credit Facilities. These debt issuance costs are being amortized as interest expense in the Company’s consolidated statements of operations over the term of the debt instrument using the straight-line method.

The Company may voluntarily prepay outstanding term loans and revolving loans under the New Credit Facilities and may reduce the unutilized portion of the New Revolving Facility at any time without premium or penalty other than customary “breakage” costs with respect to LIBOR loans.

At present LIBOR is expected to be published only on a limited basis after 2021. The Company’s New Credit Facilities do not specify a particular “hard-wired” replacement index rate (or related margin) when LIBOR becomes unavailable, but rely on the administrative agent and the Company reaching agreement on such a replacement rate (and related margin) that gives due consideration to the then prevailing market convention for determining rates of interest for syndicated loans denominated in US dollars in the United States. The Company expects to amend the New Credit Facilities to provide a market-based replacement index rate and margin prior to the time when LIBOR is no longer available.

The Credit Agreement also requires the Company to prepay outstanding term loans, subject to certain exceptions, with (a) up to 50% of the Company’s annual Excess Cash Flow (as defined in the Credit Agreement) and (b) 100% of the net cash proceeds of (i) certain asset sales and casualty and condemnation events, subject to reinvestment rights and certain other exceptions; and (ii) any incurrence or issuance of certain debt, other than debt permitted under the New Credit Facilities.

The New Term Loan Facility matures November 6, 2025 and the New Revolving Facility matures November 6, 2023. At December 31, 2020, the only outstanding amounts under the New Revolving Facility were undrawn outstanding letters of credit of $0.2 million.

All obligations under the New Credit Facilities are unconditionally guaranteed by certain of the Company’s wholly-owned domestic subsidiaries and are secured, subject to certain exceptions, by substantially all of the Company’s assets and the assets of the Company’s subsidiaries that have guaranteed the New Credit Facilities.

The New Credit Facilities contain a number of negative covenants that, subject to certain exceptions, restrict the Company’s ability and each of the Company’s subsidiaries’ ability to incur additional indebtedness; pay dividends on its capital stock or redeem, repurchase or retire its capital stock or its other indebtedness; make investments, loans and acquisitions, create restrictions on the payment of dividends or other amounts to the Company from the Company’s restricted subsidiaries; engage in transactions with its affiliates; sell assets, including capital stock of its subsidiaries; materially alter the business it conducts; consolidate or merge; incur liens; and engage in sale-leaseback transactions. If at any time, commencing with the fiscal quarter

ending March 31, 2019, the Company has revolving borrowings, unreimbursed letter of credit drawings and undrawn letters of credit outstanding in an amount in excess of 35.0% of the commitment amount under the New Revolving Facility, the Credit Agreement requires the Company to maintain a secured net leverage ratio of at least 3.25 to 1.0. The Company is in compliance with all of the above covenants at December 31, 2020.

Leases [Abstract]

Lessee, Operating Leases

LEASES

Adoption of ASC ASU No. 2016-02, Leases On January 1, 2019, the Company adopted ASU No. 2016-02 using the modified retrospective method applied to existing leases in place as of January 1, 2019. Leases entered into after January 1, 2019 are presented under the provisions of ASU No. 2016-02, while prior periods are not adjusted and continue to be reported in accordance with previous accounting guidance. Leases commencing or renewing after the adoption date are evaluated based on the guidance in ASU No. 2016-02 and may result in more finance leases being recognized even for the renewal of previously classified operating leases.

The Company elected to adopt the ‘package of practical expedients’, which permitted the Company not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the practical expedient pertaining to land easements, which allowed the Company to exclude evaluation of all existing land easements in connection with the adoption of the new lease requirements to assess whether they meet the definition of a lease. The Company did not elect the use-of-hindsight practical expedient and therefore did not reassess the lease terms for purposes of calculation of the lease liabilities and right-of-use assets at the adoption date. The Company elected the short-term lease recognition exemption for all leases that qualified. This means, for those leases that qualified, the Company did not recognize right-of-use assets or lease liabilities, and this included not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all leases other than leases of real estate, and this included not separating lease and non-lease components for all leases other than leases of real estate in transition.

The Company adopted ASU 2016-02 using the modified retrospective method, recognizing the cumulative effect of application as an adjustment to the opening balance sheet. The standard had a material impact on our consolidated balance sheets, but did not have a material impact on our consolidated statement of income or cash flows. The most significant impact was the recognition of the right-of-use asset and lease liabilities for operating leases. As of December 31, 2020 and 2019, we do not have any material finance leases.

Leases As of December 31, 2020, the Company was obligated under operating lease agreements for certain sales offices and manufacturing facilities, manufacturing equipment, vehicles, information technology equipment and warehouse space. Our leases have remaining lease terms of 1 year to 14 years, some of which may include options to extend the lease for up to 6 years, and some of which may include options to terminate the leases within 1 year.

As of December 31, 2020 and 2019, the Company’s operating lease components with initial or remaining terms in excess of one year were classified on the consolidated balance sheet as follows, together with certain supplemental balance sheet information:

In 2012, Entegris’ Korean subsidiary made commitments to produce a certain line of products in Korea. In return for this commitment, the Company had a tax holiday on income earned on sales of these products for five years and a partial holiday for two additional years. The income tax benefit attributable to this tax holiday was $4 million ($0.03 per diluted share) for the year ended December 31, 2018. The tax holiday benefit ceased during the year ended December 31, 2018.

The Company has made employment and spending commitments to Singapore. In return for those commitments, the Company has been 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 $9.4 million ($0.07 per diluted share), $5.8 million ($0.04 per diluted share) and $6.3 million ($0.04 per diluted share) for the years

ending December 31, 2020, 2019 and 2018, respectively. The 2020, 2019 and 2018 effective tax rates include additional benefits of $5.4 million, $3.3 million and $3.6 million, because the corporate tax rate in Singapore is lower than the U.S. rate.

At December 31, 2020, there were approximately $66.6 million of accumulated undistributed earnings of subsidiaries outside of the United States, all of which are considered to be indefinitely reinvested. Management estimates that no material 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, 2020 and 2019 are as follows:

(In thousands)	2020		2019
Deferred tax assets attributable to:
Accounts receivable	$	436	$	87
Inventory	4,566		6,517
Accruals not currently deductible for tax purposes	12,828		7,568

Gross deferred tax assets	60,842		46,345

Deferred tax liabilities attributable to:
Purchased intangible assets	(38,083)		(44,447)
Depreciation	(13,276)		(6,491)
Total deferred tax liabilities	(51,359)		(50,938)
Net deferred tax liabilities	$	(19,916)	$	(24,711)

Deferred tax assets are generally required to be reduced by a valuation allowance if, based on the weight of available positive and negative evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

As of December 31, 2020 and 2019, the Company had net U.S. deferred tax liabilities of $4.7 million and $12.2 million, respectively, which are composed of temporary differences and various tax credit carryforwards. Management believes that it is more likely than not that the benefit from certain state net operating loss carryforwards, state credit carryforwards and the federal foreign tax credit carryforward will not be realized. In recognition of this risk, management has provided valuation allowances of $18.6 million and $10.4 million as of December 31, 2020 and 2019, 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, 2020 will be recognized as a reduction of income tax expense.

At December 31, 2020, the Company had state operating loss and credit carryforwards of approximately $12.4 million, which begin to expire in 2021, and foreign operating loss carryforwards of $30.2 million, which begin to expire in 2021.

As of December 31, 2020 and 2019, the Company had net non-U.S. deferred tax assets of $14.1 million and $7.7 million, respectively, for which management determined based upon the available evidence a valuation allowance of $10.8 million and $9.7 million as of December 31, 2020 and 2019, 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.

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, 2020 and 2019 are as follows:

(In thousands)	2020		2019
Gross unrecognized tax benefits at beginning of year	$	16,194	$	12,295
Increase in tax positions from prior years	412		1,786
Decrease in tax positions from prior years	(453)		(54)
Increases in tax positions for current year	3,463		3,414
Settlement of tax positions for current year	(532)		(421)
Lapse in statute of limitations	(1,689)		(826)
Gross unrecognized tax benefits at end of year	$	17,395	$	16,194

The total amount of net unrecognized tax benefits that, if recognized, would effect the effective tax rate was $12.9 million at December 31, 2020.

Penalties and interest paid or received are recorded in other income, net in the consolidated statements of operations. As of December 31, 2020 and 2019, the Company had accrued interest and penalties related to unrecognized tax benefits of $4.9 million and $3.9 million, respectively. Expenses of $0.9 million, $0.6 million and $0.8 million were recognized as interest and penalties in the consolidated statements of operations for the years ended December 31, 2020, 2019 and 2018, 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 2016 and 2016, 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 2014.

Due to the expiration of various statutes of limitations and settlement of audits, it is reasonably possible that the Company’s gross unrecognized tax benefit balance may decrease within the next twelve months by approximately $2.3 million.

On January 13, 2021, the Company’s Board of Directors declared a quarterly cash dividend of $0.08 per share to be paid on February 17, 2021 to shareholders of record as of January 27, 2021.

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. Furthermore, the credit agreements governing the New Credit Facilities contain restrictions that may limit our ability to pay dividends.

Share Repurchase Program

On December 14, 2020, the Company’s Board of Directors authorized a repurchase program, effective February 16, 2021, covering the repurchase of up to an aggregate of $125.0 million of the Company’s common stock, during a period of twelve months, in open market transactions and in accordance with one or more pre-arranged stock trading plans to be established in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. This repurchase program replaced the existing repurchase program, which was originally approved in February 2020 and which will expire pursuant to its terms on February 15, 2021.

The Company repurchased $44.6 million, $74.8 million and $179.3 million of shares for the years ended December 31, 2020, 2019 and 2018, respectively.

The credit agreement governing the New Credit Facilities contains restrictions that may limit the Company’s ability to continue to repurchase shares.

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.

The weighted average remaining contractual term for options outstanding and options exercisable for all plans at December 31, 2020 was 4.4 years and 3.6 years, respectively.

For all plans, the Company had shares available for future grants of 9.0 million, 8.2 million, and 8.7 million shares at December 31, 2020, 2019 and 2018, respectively.

Under the stock plans, the total pre-tax intrinsic value of stock options exercised during the years ended December 31, 2020 and 2019 was $36.4 million and $3.2 million, respectively. The aggregate intrinsic value, which represents the total pre-tax intrinsic value based on the Company’s closing stock price of $96.10 at December 31, 2020, which theoretically could have been received by the option holders had all option holders exercised their options as of that date, was $67.9 million and $30.3 million for options outstanding and options exercisable, respectively.

Share-based payment awards in the form of stock option awards for 0.2 million, 0.3 million and 0.3 million shares were granted to employees during the years ended December 31, 2020, 2019 and 2018, respectively. Compensation expense is based on the grant date fair value. The awards vest annually over a four-year period 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, 2020, 2019 and 2018:

Employee stock options:	2020			2019			2018
Volatility	31.9		%	31.6		%	28.7		%
Risk-free interest rate	1.4		%	2.5		%	2.4		%
Dividend yield	0.6		%	0.8		%	0.9		%
Expected life (years)	4.3			4.1			3.9
Weighted average fair value per option	$	14.83		$	8.89		$	7.35

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 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 maintains the Entegris, Inc. Amended and Restated Employee Stock Purchase Plan (“ESPP”). The 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, 2020, 1.5 million shares remained available for issuance under the ESPP. Employees purchased 0.2 million, 0.2 million and 0.2 million shares, at a weighted-average price of $46.58, $28.67, and $24.86 during the years ended December 31, 2020, 2019 and 2018, 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, 2020, 2019 and 2018 is presented in the following table:

	2020			2019			2018
(Shares in thousands)	Number of shares	Weighted average grant date fair value		Number of shares	Weighted average grant date fair value		Number of shares	Weighted average grant date fair value
Unvested, beginning of year	1,254	$	27.48	1,519	$	21.24	1,857	$	15.86
Granted	437	57.46		514	34.05		509	31.40

Unvested, end of year	1,083	41.31		1,254	27.48		1,519	21.24

The weighted average remaining contractual term for unvested restricted shares at December 31, 2020 and 2019 was 1.2 years and 1.1 years, respectively.

During the years ended December 31, 2020, 2019 and 2018, the Company awarded performance-based restricted stock units for up to 0.1 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 and other key employees. Compensation expense is based on the grant date fair value. The awards vest on the third anniversary of the award date. The Company estimates the fair value of the performance shares using a Monte Carlo simulation process.

As of December 31, 2020, the total compensation cost related to unvested stock options, performance-based restricted stock units and restricted stock unit awards not yet recognized was $3.9 million, $3.4 million and $30.6 million, respectively, and is expected to be recognized over the next 2.5 years on a weighted-average basis.

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. 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, 2020, 2019 and 2018:

Under the Plan, eligible employees may defer a portion of their pre-tax wages, up to the Internal Revenue Service annual contribution limit. Entegris matches employees’ contributions to a maximum match of 4% of the employee’s eligible wages. The employer matching contribution expense under the 401(k)Plan was $8.2 million, $7.1 million and $6.1 million in the fiscal years ended December 31, 2020, 2019 and 2018, respectively.

Assumptions used in determining the benefit obligation and net periodic benefit cost for the Company’s pension plans for the years ended December 31, 2020, 2019 and 2018 are presented in the following table as weighted-averages:

	2020		2019		2018
Benefit obligations:
Discount rate	0.39	%	0.53	%	0.76	%
Rate of compensation increase	2.33	%	2.91	%	3.08	%
Net periodic benefit cost:
Discount rate	0.98	%	1.29	%	1.66	%
Rate of compensation increase	2.33	%	3.51	%	3.18	%
Expected return on plan assets	1.82	%	1.51	%	1.89	%

The pension plans’ expected return on assets as shown above is based on management’s expectations of long-term average rates of return to be achieved by the underlying investment portfolios. In establishing this assumption, management considers historical and expected returns for the asset classes in which the plans are invested, as well as current economic and capital market conditions. The discount rate primarily used by the Company is based on market yields at the valuation date on government bonds as well as the estimated maturity of benefit payments.

Plan Assets

At December 31, 2020, the majority of the Company’s pension plan assets are deposited with the Bank of Taiwan in the form of money market funds, where the Bank of Taiwan is the assigned funding vehicle for the statutory retirement benefit. The remaining portion of the Company’s plan assets is deposited in a German insurance company’s investment fund.

SEGMENT INFORMATIONThe Company’s financial segment reporting reflects an organizational alignment intended to leverage the Company’s unique breadth of capabilities to create mission-critical microcontamination control products, specialty chemicals and advanced

materials handing solutions that maximize manufacturing yields, reduce manufacturing costs and enable higher device performance for its customers. While these segments have separate products and technical know-how, they share a common business systems and processes, technology centers, and strategic and technology roadmaps. The Company’s business is reported in the following three segments:

•Specialty Chemicals and Engineered Materials: SCEM provides high-performance and high-purity process chemistries, gases and materials and safe and efficient delivery systems to support semiconductor and other advanced manufacturing processes.

•Microcontamination Control: MC offers solutions to filter and purify critical liquid chemistries and gases used in semiconductor manufacturing processes and other high-technology industries.

•Advanced Materials Handling: AMH develops solutions to monitor, protect, transport, and deliver critical liquid chemistries and substrates for a broad set of applications in the semiconductor industry and other high-technology industries.

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, that is, at approximate market prices. 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, amortization of intangible assets and income tax expense.

Corporate assets consist primarily of cash and cash equivalents, deferred tax assets and deferred tax charges.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2020

Accounting Policies [Abstract]

Nature of Operations

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

Principles of Consolidation

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

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.

Cash and Cash Equivalents

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 Doubtful Accounts

Allowance for Doubtful Accounts 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 doubtful accounts that management believes is adequate to cover expected losses on trade receivables.

Inventories

Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined by the first-in, first-out (FIFO) method.

Leases

Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating leases. Lease liabilities for operating leases are classified in “Other accrued liabilities” and “Long-term lease liabilities” in our consolidated balance sheet. We do not have material financing leases.

Operating assets and liabilities 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 includes prepaid lease payments and excludes 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.

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 Property, plant and equipment are carried at cost and are depreciated on the straight-line method over the estimated useful lives of the assets. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and gains or losses are recognized in the same period. 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).

Fair Value of Financial Instruments

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.

The fair value of long-term debt, including current maturities, based upon models utilizing market observable (Level 2) inputs and credit risk, was $1,126.6 million at December 31, 2020 compared to the carrying amount of long-term debt, including current maturities, of $1,085.8 million at December 31, 2020.

Goodwill and Intangible Assets

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. The Company compares the carrying value of its reporting units, including goodwill, to their fair value. For reporting units in which the assessment indicates that it is more likely than not that the fair value is more than its carrying value, goodwill is not considered impaired. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. Based on its annual analysis, the Company determined there was no indication of impairment of goodwill and the estimated fair value of each reporting unit substantially exceeded its carrying value. 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

Derivative Financial Instruments The Company records derivatives as assets or liabilities on the balance sheet and measures such instruments at fair value. Changes in fair value of derivatives are recorded each period in the Company’s consolidated statements of operations.The Company periodically enters into forward foreign currency contracts to reduce exposures relating to rate changes in certain foreign currencies. Certain exposures to credit losses related to counterparty nonperformance exist. However, the Company does not anticipate nonperformance by the counterparties since they are large, well-established financial institutions. None of these derivatives is accounted for as a hedge transaction. Accordingly, changes in the fair value of forward foreign currency contracts are recorded as other expense (income), net, in the Company’s consolidated statements of operations. The fair values of the Company’s derivative financial instruments are based on prices quoted by financial institutions for these instruments.

Foreign Currency Translation

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 weighted 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 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 incurred are recorded in cost of sales in the Company’s consolidated statements of operations.

Engineering,Research and Development Expenses

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

Share-Based Compensation

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.

Income Taxes

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 (Loss)

Comprehensive Income (Loss) Comprehensive income (loss) 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, and minimum pension liability adjustments are included in accumulated other comprehensive loss. Comprehensive income (loss) and the components of accumulated other comprehensive loss are presented in the accompanying consolidated statements of comprehensive income (loss) and consolidated statements of equity.

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted in 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities are required to use a new forward-looking “expected loss” model that replaced the current “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The Company adopted this new guidance in the first quarter of fiscal 2020. The adoption of ASU 2016-13 did not impact the consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The Company adopted this guidance in 2020. The adoption of ASU 2018-14 did not impact the consolidated financial statements.
