Waters Products and Markets

High-Performance and Ultra-Performance Liquid Chromatography

HPLC is a standard technique used to identify and analyze the constituent components of a variety of chemicals and other materials. The Company believes that HPLC’s performance capabilities enable it to separate, identify and quantify a high proportion of all known chemicals. As a result, HPLC is used to analyze substances in a wide variety of industries for research and development purposes, quality control and process engineering applications.

The most significant end-use markets for HPLC are those served by the pharmaceutical and life science industries. In these markets, HPLC is used extensively to understand diseases, identify new drugs, develop manufacturing methods and assure the potency and purity of new pharmaceuticals. HPLC is also used in a variety of other applications, such as analyses of foods and beverages for nutritional labeling and compliance with safety regulations and the testing of water and air purity within the environmental testing industry, as well as applications in other industries, such as chemical and consumer products. Waters also has in vitro diagnostic labelled products that are used as general-purpose instruments for clinical diagnostic applications, such as newborn screening and therapeutic drug management, in countries where these products are registered. HPLC is also used by universities, research institutions and governmental agencies, such as the United States Food and Drug Administration (“FDA”) and the United States Environmental Protection Agency (“EPA”) and their foreign counterparts that mandate safety and efficacy testing.

In 2004, Waters introduced a novel technology that the Company describes as ultra-performance liquid chromatography that utilizes a packing material with small, uniform diameter particles and a specialized instrument, the ACQUITY^TM UPLC^TM System, to accommodate the increased pressure and narrower chromatographic bands that are generated by these small and tightly packed particles. By using the ACQUITY UPLC System, researchers and analysts are able to achieve more comprehensive chemical separations and faster analysis times in comparison with many analyses previously performed by HPLC. In addition, in using the ACQUITY UPLC System, researchers have the potential to extend the range of applications beyond that of HPLC, enabling them to uncover more levels of scientific information. While offering significant performance advantages, the ACQUITY UPLC System is also compatible with the Company’s software products and the general operating protocols of HPLC. For these reasons, the Company’s customers and field sales and support organizations are well positioned to utilize this innovative technology and instrument. In 2018, the Company introduced the ACQUITY Arc^TM Bio System, a versatile, iron-free, bio-inert, quaternary liquid chromatograph specifically engineered to improve bioseparation analytical methods. The Company also introduced the ACQUITY UPLC PLUS System series in 2018, consisting of the ACQUITY UPLC H-Class PLUS System, ACQUITY UPLC H-Class PLUS Bio System and ACQUITY UPLC I-Class PLUS Systems, which incorporate foundational enhancements into the legacy systems.

Waters manufactures LC instruments that are offered in configurations that allow for varying degrees of automation, from component configured systems for academic teaching and research applications to fully automated systems for regulated and high sample throughput testing, and that have a variety of detection technologies, from optical-based ultra-violet absorbance, refractive index and fluorescence detectors to a suite of MS-based detectors, optimized for certain analyses.

In 2019, the Company introduced the ACQUITY Advanced Polymer Chromatography^TM System, which is the first fully solvent-compatible UPLC System to perform size exclusion, gradient polymer elution and solvent compatible reversed-phase liquid chromatographic separations on a single platform. The all-in-one system gives research scientists greater analytical versatility and speed when conducting research on next-generation polymers. In 2020, the Company introduced the Waters Arc HPLC System, a new HPLC system for routine testing in the pharmaceutical, food, academic and materials markets. A key target application is quality control in laboratories performing batch release tests on small molecule pharmaceuticals. In 2021, the Company introduced the new ACQUITY Premier LC solution and the Arc Premier System both featuring Waters MaxPeak^TM High Performance Surface (“HPS”) Technology. MaxPeak HPS Technology, which was first introduced with the Company’s introduction of ACQUITYPremier Columns in 2020, is a surface technology that forms a barrier between the sample and the metal surfaces of both the system and column, eliminating the need for system passivation, mitigating the loss of metal-sensitive analytes and yielding higher quality data in less time and effort.

During the second half of 2023, Waters introduced the DynaPro^TM ZetaStar^TM instrument through its Wyatt Technology^TM portfolio for nanoparticle analysis. The new instrument simultaneously enables dynamic and static light scattering and dynamic and electrophoretic light scattering measurements, all in one device. By combining multiple light scattering techniques and automatically assessing data quality and performing adaptive data capture, the ZetaStar instrument delivers both increased sensitivity and faster measurements to aid the precise development of complex biologics, using extremely low sample volumes.

The primary consumable products for LC instruments are chromatography columns. These columns are packed with separation media used in the LC testing process and are typically replaced at regular intervals. The chromatography column contains one of several types of packing material, typically stationary phase particles made from silica or polymeric resins. As a pressurized sample is introduced to the column inlet and permeates through the packed column, it is separated into its constituent components.

Waters HPLC columns can be used on Waters-branded and competitors’ LC systems. The Company believes that it is one of a few suppliers in the world that manufactures silica and polymeric resins, packs columns and distributes its own products. In doing so, the Company believes it can better ensure product consistency, a key attribute for its customers in quality control laboratories and can react quickly to new customer requirements. The Company believes that its ACQUITY UPLC Columns are used primarily on its ACQUITY UPLC Systems and, furthermore, that its ACQUITY UPLC Systems primarily use ACQUITY UPLC Columns. In 2019, the Company introduced the BioResolve^TM SCX mAb Columns and VanGuard^TMFIT Cartridge technologies. These new cation exchange column lines with specialized consumables are designed to simplify and improve the characterization and monitoring of monoclonal antibody (“mAb”) therapeutics, as well as enable mAb charge-variant analyses as required by the World Health Organization, the FDA and the International Conference on Harmonization for confirming the efficacy and safety of biologics and biosimilars with discovery, development and manufacturing applications. In 2020, Waters introduced ACQUITY Premier Columns, at the time a new family of premium sub-2-micron columns featuring MaxPeak HPS Technology. The columns are for use with any brand of UPLC System and can measurably improve data quality by mitigating the loss of sample analytes due to analyte-to-surface interactions.

The Company’s precision chemistry consumable products also include environmental and nutritional safety testing products, including Certified Reference Materials and Proficiency Testing products. Laboratories around the world and across multiple industries use these products for quality control and proficiency testing and also purchase product support services required to help with their federal and state mandated accreditation requirements or with quality control over critical pharmaceutical analysis.

In 2023, the Company introduced the first in a new line of size exclusion chromatography columns aimed at improving analysis while lowering the cost of gene therapies, specifically adeno-associated viral (“AAV”) vectors. The new Waters XBridge^TM Premier GTx BEH^TM size exclusion chromatography columns double the

speed of measuring the potency and safety of AAVs. Combining the columns with light scattering technologies from its Wyatt Technology portfolio deepens the level of information acquired from a single experiment and optimizes the manufacturing of these novel gene delivery vehicles.

In 2020, the Company acquired all of the outstanding stock of Andrew Alliance, S.A. (“Andrew Alliance”). Andrew Alliance offers lab workflow automation solutions with the combination of its software platform and smart, connected laboratory equipment and accessories. The addition of Andrew Alliance to our portfolio has allowed us to positively impact our customers’ workflows by improving the repeatability, performance and speed of laboratory operations and chemistry workflows.

In 2023, the Company introduced the Alliance^TM iS HPLC System, the next-generation intelligent HPLC System, designed to reduce compliance risk by adding new levels of proactive error detection, troubleshooting and ease-of-use. When combined with Waters compliance-ready Empower^TM Chromatography Software and eConnect^TM HPLC Columns, the Alliance iS HPLC System streamlines the task of making accurate and precise measurements by detecting and eliminating common errors. In doing so, the Alliance iS HPLC System helps quality control laboratories to consistently meet quality, safety, compliance and on-time product delivery goals. This system also integrates with the cloud-native waters_connect^TM System Monitoring Software enabling real-time monitoring of the Alliance iS HPLC System and any other chromatography instruments controlled by Empower Software. Laboratory managers can view the live status of their HPLC instrument fleet from anywhere and at any time to further improve equipment utilization and overall productivity.

Also in 2023, the Company introduced the new bioprocess walk-up solutions designed to further simplify biologic sample preparation and analysis. This solution eliminated the need to send bioreactor samples to a central laboratory for analysis making it even easier to accelerate upstream bioprocess development by up to six weeks over traditional methods.

Mass Spectrometry and Liquid Chromatography-Mass Spectrometry

MS is a powerful analytical technology that is used to identify unknown compounds, to quantify known materials and to elucidate the structural and chemical properties of molecules by measuring the masses of molecules that have been converted into ions.

The Company is a technology and market leader in the development, manufacture, sale and service of MS instruments and components. These instruments are typically integrated and used along with other complementary analytical instruments and systems, such as LC, chemical electrophoresis and gas chromatography. A wide variety of instrumental designs fall within the overall category of MS instrumentation, including devices that incorporate quadrupole, ion trap, time-of-flight (“Tof”), magnetic sector and ion mobility technologies. Furthermore, these technologies are often used in tandem to maximize the speed and/or efficacy of certain experiments.

Currently, the Company offers a wide range of MS instrument systems utilizing various combinations of quadrupole, Tof and ion mobility designs. These instrument systems are used in drug discovery and development, as well as for environmental, clinical and nutritional safety testing. The overwhelming majority of mass spectrometers sold by the Company are designed to utilize an LC system and a liquid compatible interface (such as an electrospray ionization source) as the sample introduction device. These products supply a diverse market with a strong emphasis on the pharmaceutical, biomedical, clinical, food and beverage and environmental market segments worldwide.

MS is an increasingly important detection technology for LC. The Company’s smaller-sized mass spectrometers, such as the single quadrupole detector and the tandem quadrupole detector (“TQD”), are often referred to as LC “detectors” and are typically sold as part of an LC system or as an LC system upgrade. Larger quadrupole systems, such as the Xevo^TM TQ MS System and Xevo TQ-S MS System, are used primarily for experiments performed for late-stage drug development, including clinical trial testing. Quadrupole time-of-flight

(“Q-Tof”) instruments, such as the Company’s SYNAPT^TM G2-S HDMS System, are often used to analyze the role of proteins in disease processes, an application sometimes referred to as “proteomics.”

LC and MS are typically embodied within an analytical system tailored for either a dedicated class of analyses or as a general-purpose analytical device. An increasing percentage of the Company’s customers are purchasing LC and MS components simultaneously and it has become common for LC and MS instrumentation to be used within the same laboratory and operated by the same user. The descriptions of LC and MS above reflect the historical segmentation of these analytical technologies and the historical categorization of their respective practitioners. Increasingly in today’s instrument market, this segmentation and categorization is becoming obsolete as a high percentage of instruments used in the laboratory embody both LC and MS technologies as part of a single device. In response to this development and to further promote the high utilization of these hybrid instruments, the Company has organized its Waters operating segment to develop, manufacture, sell and service integrated LC-MS systems.

In 2019, the Company introduced the BioAccord^TMSystem, a liquid chromatography-mass spectrometry solution that expands access to high-resolution time-of-flight mass spectrometry capabilities. The system provides new levels of user experience with automated setup and self-diagnosis delivered through an intuitive user interface. Also in 2019, the Company introduced the SELECT SERIES^TMCyclic^TM IMS System, which seamlessly integrates cyclic ion mobility technology into a high-performance research-grade time-of-flight mass spectrometer. In addition, the Company introduced the SYNAPT XS System, a new highly flexible, high-resolution mass spectrometer for research and development labs focused on discovery applications. The Company also reinforced its tandem quadrupole mass spectrometry portfolio during the current year with upgrades to the Xevo TQ-S micro MS System and the introduction of the new Xevo TQ-S cronos MS System. The Xevo TQ-S micro System features new performance enhancements that bring the quantitation of highly polar, ionic compounds in food to a higher level. The Xevo TQ-S cronos System is a new, tandem quadrupole mass spectrometer purposely built for routine quantitation of large numbers of small-molecule organic compounds over a wide concentration range. The Xevo TQ-S micro System and the Xevo TQ-S cronos System are also well suited to meet regulatory requirements for pesticide residue analysis, the monitoring for contaminants in processed foods, identifying drugs of abuse, and performing impurity profiling of pharmaceuticals. In 2020, the Company introduced the RADIAN^TMASAP^TM System, a novel direct mass detector engineered for non-mass spectrometry experts to conduct fast and accurate analyses of solids and liquids with minimal sample prep. Also in 2020, the Company introduced enhancements for the Waters Xevo G2-XS QTof System, SYNAPT XS System and SELECT SERIES Cyclic IMS System, including a new fragmentation technique and imaging option.

In 2021, the Company introduced the SELECT SERIES MRT MS System, a high-resolution mass spectrometer that combines Multi-Reflecting Time-of-Flight (“MRT”) technology with enhanced desorption electrospray ionization and new matrix-assisted laser desorption ionization imaging sources. The platform will serve as the basis for Waters next generation Tof instruments with applications in pharmaceutical, biomedical, natural products, and materials research. Also in 2021, the Company released the ACQUITY RDa^TM Detector featuring SmartMS^TM Technology, the company’s newest Tof MS designed to improve the ease and reliability of small molecule analysis for pharmaceutical, academic, food, and forensic applications. The Company also introduced a new peptide multi-attribute method workflow for the BioAccord LC-MS System in 2021, which is an end-to-end workflow for analyzing monoclonal antibodies and other protein and peptide-based drugs.

In 2022, the Company introduced the Xevo TQ Absolute System, the most sensitive and compact benchtop tandem mass spec in its class. The Company introduced the new Xevo G3 Q-Tof Mass Spectrometer with CONFIRM Sequence, a new oligonucleotide sequencing confirmation app for the waters_connect Software platform and an electrospray ionization source for the high-resolution SELECT SERIES MRT Mass Spectrometer.

Based upon 2023 reports from independent marketing research firms and publicly disclosed sales figures from competitors, the Company believes that it is one of the world’s largest manufacturers and distributors of LC and LC-MS instrument systems, chromatography columns and other consumables and related services.

The Company has been a developer and supplier of software-based products that interface with both the Company’s and other suppliers’ instruments. The Company’s newest software technology for mass spectrometry is the waters_connect Software platform. In 2019, the Company introduced the first of a series of applications on this platform supporting the BioAccord System and the Xevo G2 XS Mass Spectrometer. These applications support biopharmaceutical workflows, simplifying the collection of often complex LCMS data for use in biopharmaceutical development and into QC where it is used to assure the quality of existing medicines and new drug formulations. The platform design of waters_connect Software has enabled rapid delivery of several major updates including new biopharma application workflows designed in close collaboration with biopharmaceutical innovators to solve specific challenges they face with existing solutions. The platform also provides the foundation for the connected lab of the future where data is no longer siloed but can be securely shared among a community of connected scientists. The waters_connect Software joins the existing suite of informatics products: Empower Chromatography Data Software, MassLynx^TM Mass Spectrometry Software and NuGenesis^TM Scientific Data Management System, each of which is used to support innovations within world-leading institutions. In 2020, Waters announced the availability of Empower BC LAC/E^TM Solution with SecureSync, an enhanced solution to preserve the ability for laboratories to work locally when organizations with distributed laboratory environments experience an enterprise interruption.

On December 15, 2020, the Company acquired all of the outstanding stock of Integrated Software Solutions Pty Limited and its two operating subsidiaries Integrated Software Solutions Limited and Integrated Software Solutions USA, LLC (collectively, “ISS”). ISS offers clinical laboratory software systems that support and further expand product offerings within our clinical business. The net assets acquired primarily relate to ISS’ laboratory information system, OMNI-Lab.

In 2022, the Company introduced a new Per-and Polyfluoroalkyl Substances (“PFAS”) quantitation workflow enabled by enhancements to its waters_connect Software for quantitation software and the Company introduced Extraction+^TM Connected Device, a new software-controlled product for the Waters Andrew+^TM Pipetting Robot that automates the preparation of biological, food, forensics and environmental samples by solid phase extraction.

In 2023, the Company introduced the next generation Xevo TQ Absolute IVD Mass Spectrometer, expanding its family of MassTrak^TM IVD LC-MS/MS Systems for clinical diagnostic applications. The powerful analytical performance of the Xevo TQ Absolute IVD Mass Spectrometer is up to five times more sensitive for quantifying clinical analytes. This sensitivity enables clinical laboratories to detect and measure trace level analytes within a sample at lower detection levels than previously possible. It can also extend the testing capabilities of the clinical laboratory to include lower volume samples obtained in less-invasive assays such as saliva, breath, dried blood spots and multiplex panels and large molecules. The new MassTrak LC-MS/MS IVD System includes the ACQUITY UPLC I-Class PLUS System with the Xevo TQ Absolute IVD Mass Spectrometer. The ACQUITY UPLC I-Class PLUS System is designed to deliver rapid and accurate sample analysis to enhance the sensitivity of any mass spectrometer and simplify the characterization of the most complex sample. The Xevo TQ Absolute IVD System provides more consistent instrument-to-instrument performance, with a user-friendly design that maximizes service uptime. Its innovative design is also 45% smaller and uses 50% less nitrogen gas and electricity than comparable tandem quadrupole-mass spectrometry systems, making it ideal for hospital labs and independent commercial labs with both sustainability and business growth goals to meet.

In addition, in 2023, the Company introduced the industry’s first targeted imaging mass spectrometer based on its Xevo TQ Absolute Tandem Quadrupole Mass Spectrometer which is the most sensitive and compact mass spectrometer in its class. The new instrument combines the Waters DESI XS source with the Xevo TQ Absolute

System and is five times more sensitive and five times faster than discovery-based imaging systems at precisely determining whether a particular small molecule drug product, and how much of it, reaches its intended target, such as a brain, liver or lung, in a test subject.

Also in 2023, the Company announced new updates to its SELECT SERIES MRT System that increases its specificity and utility for UPLC-MS/MS metabolomics and drug discovery applications and for mass spectrometry imaging experiments. The MRT System now offers 50% higher resolution, making it capable of 300,000 FWHM resolution, a 3X faster scan rate and parts-per-billion mass accuracy. These MRT System enhancements are designed to help research scientists unambiguously identify analytes of interest in samples of blood, urine and tissue, contributing to a greater understanding of molecules and their mechanisms of action in numerous scientific fields. It is compatible with numerous MS imaging sources including DESI and MALDI, and generates crystal-clear, high-resolution images without compromising mass spectral resolution or accuracy.

In addition, in 2023, the Company combined its BioAccord LC-MS System and the Waters Andrew+ Pipetting Robot, connecting via new protocols in OneLab^TMSoftware to create fully integrated and easy-to-use bioprocess walk-up solutions. It is designed to enable less experienced LC-MS users to acquire critical quality attribute data for analysis of drug product and cell culture media. Capturing data directly at the bioproduction laboratory can help bioprocess engineers improve process understanding, leading to more robust manufacturing processes and accelerated development timelines.

TA Products and Markets

Thermal Analysis, Rheometry and Calorimetry

Thermal analysis measures the physical or thermodynamic characteristics of materials as a function of temperature. Changes in temperature affect several characteristics of materials, such as their heat flow

characteristics, physical state, weight, dimension and mechanical and electrical properties, which may be measured by one or more thermal analysis techniques, including calorimetry. Consequently, thermal analysis techniques are widely used in the development, production and characterization of materials in various industries, such as plastics, chemicals, automobiles, pharmaceuticals and electronics.

Rheometry instruments often complement thermal analyzers in characterizing materials. Rheometry characterizes the flow properties of materials and measures their viscosity, elasticity and deformation under different types of “loading” or other conditions. The information obtained under such conditions provides insight into a material’s behavior during processing, packaging, transport, usage and storage.

Thermal analysis, rheometry and calorimetry instruments are heavily used in material testing laboratories and, in many cases, provide information useful in predicting the suitability and stability of industrial polymers, fine chemicals, pharmaceuticals, water, metals and viscous liquids in various industrial, consumer goods and healthcare products, as well as for life science research. As with systems offered by Waters, a range of instrument configurations is available with increasing levels of sample handling and information processing automation. In addition, systems and accompanying software packages can be tailored for specific applications.

In 2020, TA introduced the new Discovery^TM X3^TM Differential Scanning Calorimeter (“X3 DSC”), Discovery Hybrid Rheometers and TAM IV Micro XL isothermal microcalorimeter. The X3 DSC accelerates productivity in customers’ laboratories by enabling three samples to be measured in a single experiment, compared to the single-sample series operation of the other available DSC offerings in the market. This particularly addresses a need in high-throughput laboratories in industries such as composites, electronics and polymer manufacturing. The new line of Discovery Hybrid Rheometers provides increased sensitivity and versatility of rheometry measurements, supporting the development of next-generation, high-performance materials by improving the productivity and efficiency of materials science research. The TAM IV Micro XL isothermal calorimeter supports the development of new battery chemistries by measuring self-discharge and unwanted reactions that reduce battery life and efficiency.

In 2021, TA introduced the TMA 450 RH Instrument and the Discovery SA Instrument. The TMA 450 RH Instrument provides measurements of dimensional compatibility of materials under controlled temperature and humidity that are important for the development of new electronic devices. The Discovery SA Instrument is used in pharmaceutical development to assess the impact of moisture in drug product processing and storage on crystalline structure, which is related to drug product efficacy.

Similar to Waters, the servicing and support of TA’s instruments is an important source of revenue and represented more than 25% of sales for TA in 2023. TA operates independently from the Waters operating segment, though many of its overseas offices are jointly occupied with Waters to achieve operational efficiencies. TA has dedicated field sales and service operations. Service sales are primarily derived from the sale of support plans, replacement parts and billed labor fees associated with the repair, maintenance and upgrade of installed systems.

Global Customers

The Company typically has a broad and diversified customer base that includes pharmaceutical accounts, other industrial accounts, universities and governmental agencies. Purchase of the Company’s instrument systems is often dependent on its customers’ capital spending, or funding as in the cases of academic, governmental and research institutions, which often fluctuate from year to year. The pharmaceutical segment represents the Company’s largest sector and includes multinational pharmaceutical companies, generic drug manufacturers, contract research organizations (“CROs”) and biotechnology companies. The Company’s other industrial customers include chemical manufacturers, polymer manufacturers, food and beverage companies and environmental testing laboratories. The Company also sells to universities and governmental agencies worldwide. The Company’s technical sales and support staff members work closely with its customers in developing and implementing applications that meet their full range of analytical requirements. During 2023, 57% of the Company’s net sales were to pharmaceutical accounts, 31% to other industrial accounts and 12% to academic institutions and governmental agencies. Although the Company transacts business with various government agencies, no government contract is of such magnitude that a renegotiation of profits or termination of the contract at the election of the government agency would have a material adverse effect on the Company’s financial results.

The Company typically experiences seasonality in its orders that is reflected as an increase in sales in the fourth quarter, as a result of purchasing habits for capital goods of many customers who tend to exhaust their spending budgets by calendar year-end. The Company does not rely on any single customer for a material portion of its sales. During fiscal years 2023, 2022 and 2021, no single customer accounted for more than 2% of the Company’s net sales.

Sales and Service

The Company has one of the largest direct sales and service organizations focused exclusively on the analytical workflows offered by the Company. Across these product technologies, using respective specialized sales and service workforces, the Company serves its customer base with 85 sales offices throughout the world as of December 31, 2023 and approximately 4,300, 4,500 and 4,300 field representatives in 2023, 2022 and 2021, respectively. This investment in sales and service personnel serves to maintain and expand the Company’s installed base of instruments. The Company’s sales representatives have direct responsibility for account relationships, while service representatives work in the field to install instruments, train customers and minimize instrument downtime. In-house and field-based technical support representatives work directly with customers, providing them assistance with applications and procedures on Company products. The Company provides customers with comprehensive information through various corporate and geographic-specific internet websites and product literature, and also makes consumable products available through electronic ordering facilities and a dedicated catalog.

Raw Materials

The Company purchases a variety of raw materials, primarily consisting of high temperature alloy sheet metal and castings, forgings, pre-plated metals and electrical components from various vendors. The materials used by

the Company’s operations are generally available from a number of sources and in sufficient quantities to meet current requirements subject to normal lead times.

The Company is subject to rules of the Securities and Exchange Commission (“SEC”) under the Dodd-Frank Wall Street Reform and Consumer Protection Act, which require disclosure as to whether certain materials (tantalum, tin, gold and tungsten), known as conflict minerals, which may be contained in the Company’s products, are mined from the Democratic Republic of the Congo and adjoining countries. In 2022, the Company was not able to determine with certainty the country of origin of some of the conflict minerals in its manufactured products. However, the Company does not have knowledge that any of its conflict minerals originated from the Democratic Republic of the Congo or adjoining countries. The Company is in the process of evaluating its 2023 supply chain, and the Company plans to file its 2023 Form SD with the SEC in May 2024. The results of this and future evaluations may impose additional costs and may introduce new risks related to the Company’s ability to verify the origin of any conflict minerals contained in its products.

In addition, the Company continues to monitor environmental, health and safety regulations in countries in which it operates throughout the world, in particular, European Union and China Restrictions on the use of certain Hazardous Substances in electrical and electronic equipment and European Union Waste Electrical and Electronic Equipment directives. Further information regarding these regulations is available on the Company’s website, www.waters.com, under the caption “About Waters / Corporate Governance”.

Research and Development

The Company maintains an active research and development program focused on the development and commercialization of products that extend, complement and update its existing product offering. The Company’s research and development expenditures for 2023, 2022 and 2021 were $175 million, $176 million and $168 million, respectively.

Nearly all of the Company’s LC products have been developed at the Company’s main research and development center located in Milford, Massachusetts, with input and feedback from the Company’s extensive field organizations and customers. The majority of the Company’s MS products are developed at facilities in England and most of the Company’s current materials characterization products are developed at the Company’s research and development center in New Castle, Delaware. At December 31, 2023, 2022 and 2021, there were approximately 1,200 employees involved in the Company’s research and development efforts. The Company has increased research and development expenses from its continued commitment to invest significantly in new product development and existing product enhancements, and as a result of acquisitions. Despite the Company’s active research and development programs, there can be no assurance that the Company’s product development and commercialization efforts will be successful or that the products developed by the Company will be accepted by the marketplace.

In 2020, the Company opened a new research laboratory in Cambridge, MA, which serves as a strategic, collaborative space in the community, where Waters can partner with academia, research and industry to accelerate the next generation of scientific advancements.

Human Capital

We believe that our people differentiate our business and are vital to our continued success. As a result, we have made important investments in our workforce through initiatives and programs that support talent development and inclusion and enhance our Total Rewards programs.

Employees

The Company employed approximately 7,900, 8,200 and 7,800 employees at December 31, 2023, 2022 and 2021, respectively, with approximately 38% of the Company’s employees located in the United States. The

Company believes its employee relations are generally good. The Company’s employees are not unionized or affiliated with any internal or external labor organizations.

In July 2023, the Company made organizational changes to better align its resources with its growth and innovation strategies, resulting in a worldwide workforce reduction that impacted approximately 5% of the Company’s employees.

Talent Development

We believe that our future success depends in a significant part on our continued ability to attract and retain highly skilled employees and then contribute to the growth and development of these employees.

We further the growth and development of our employees by investing in various programs, digital platforms and workshops that build professional and technical skills. 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.

Inclusion & Diversity

We believe inclusion is a core tenet of organizational success and that fostering a sense of inclusivity allows our employees to maximize their performance contribution to our business. In 2021, we hired our first Director of Diversity, Equity and Inclusion to help strategize and focus our inclusivity efforts. As part of our company-led initiatives to drive an inclusive workplace, we have created Employee Circles and Employee Hubs, which are voluntary, employee-driven employee resource groups worldwide to foster a diverse and inclusive culture through awareness, education and employee connections. Our five Employee Circles are people of color, LGBTQ+ pride, veterans, women and disability. Our global Employee Circles provide opportunities for Waters employees to connect with teammates throughout the world, while Employee Hubs encourage engagement at the local level. Our Employee Circles and Hubs led various initiatives in 2023 to build a strong culture of inclusion and awareness. We have also rolled out training to all employees to support an inclusive culture that values diverse perspectives.

We believe that part of fostering a diverse, inclusive and equitable organization and workforce means understanding the makeup of our current employees. As of December 31, 2023, our workforce identifies as:

• 32% female, with women occupying 34% of company leadership roles (defined as Senior Director or above) compared with 22% in 2017, an increase of 12 percentage points; and

• 23% racially and/or ethnically diverse, with 11% of our workforce identifying as Asian, 3.5% as identifying as Black or African American, 7% identifying as Hispanic/Latinx and 1% identifying as two or more races.

Recruitment

Waters has focused on expanding diversity in our recruitment processes, including developing partnerships with organizations that support diversity in hiring and employee engagement. Current partnerships include: the National Organization of Black Chemists and Chemical Engineers, Out in Tech, Vercida, Home Base and Fairygodboss to expand the pipeline of strong candidates.

Health and Safety

The health and safety of our employees is our highest priority. Through online and in-person training programs, we believe that we foster a safe workplace and ensure that all employees are empowered to prevent accidents and injuries.

We manufacture products deemed essential to critical infrastructure, including health and safety, food and agriculture, and energy, and as a result, the majority of our production sites continued operating during the COVID-19 pandemic.

Competition

The analytical instrument systems, supplies and services market is highly competitive. The Company encounters competition from several worldwide suppliers and other companies in both domestic and foreign markets for each of its three primary technologies. The Company competes in its markets primarily on the basis of product performance, reliability, service and, to a lesser extent, price. Competitors continuously introduce new products and have instrument businesses that are generally more diversified than the Company’s business. Some competitors have greater financial resources and broader distribution than the Company’s.

In the markets served by Waters, the Company’s principal competitors include: Agilent Technologies, Inc., Shimadzu Corporation, Bruker Corporation, Danaher Corporation and Thermo Fisher Scientific Inc. In the markets served by TA, the Company’s principal competitors include: Perkin Elmer, Inc., NETZSCH-Geraetebau GmbH, Thermo Fisher Scientific Inc., Malvern PANalytical Ltd., a subsidiary of Spectris plc, Anton-Paar GmbH and others not identified here.

The market for consumable LC products, including separation columns, is highly competitive and generally more fragmented than the analytical instruments market. The Company encounters competition in the consumable columns market from chemical companies that produce column sorbents and small specialized companies that primarily pack purchased sorbents into columns and subsequently package and distribute columns. The Company believes that it is one of the few suppliers that processes silica and polymeric resins, packs columns and distributes its own products. The Company competes in this market on the basis of performance, reproducibility, reputation and, to a lesser extent, price. In recent years, the Company’s principal competitors for consumable products have included: Danaher Corporation; Merck KGaA; Agilent Technologies, Inc.; General Electric Company and Thermo Fisher Scientific Inc. The ACQUITY UPLC Instrument is designed to offer a predictable level of performance when used with ACQUITY UPLC Columns and the Company believes that the expansion of the ACQUITY UPLC Instrument base will enhance its chromatographic column business because of the high level of synergy between ACQUITY UPLC Columns and the ACQUITY UPLC Instruments.

Patents, Trademarks and Licenses

The Company owns a number of United States and foreign patents and has patent applications pending in the United States and abroad. Certain technology and software has been acquired or is licensed from third parties. The Company also owns a number of trademarks. The Company’s patents, trademarks and licenses are viewed as valuable assets to its operations. However, the Company believes that no one patent or group of patents, trademark or license is, in and of itself, essential to the Company such that its loss would materially affect the Company’s business as a whole.

Environmental Matters and Climate Change

The Company is subject to foreign and U.S. federal, state and local laws, regulations and ordinances that (i) govern activities or operations that may have adverse environmental effects, such as discharges to air and water as well as handling and disposal practices for solid and hazardous wastes, and (ii) impose liability for the costs of cleaning up and certain damages resulting from sites of past spills, disposals or other releases of hazardous substances. The Company believes that it currently conducts its operations and has operated its business in the past in substantial compliance with applicable environmental laws. From time to time, Company operations have resulted or may result in noncompliance with environmental laws or liability for cleanup pursuant to environmental laws. The Company does not currently anticipate any material adverse effect on its

operations, financial condition or competitive position as a result of its efforts to comply with environmental laws.

The Company is sensitive to the growing global debate with respect to climate change. An internal sustainability working group develops increasingly robust data with respect to the Company’s utilization of carbon producing substances in an effort to continuously reduce the Company’s carbon footprint. In 2019, the Company published a sustainability report identifying the various actions and behaviors the Company adopted in 2018 concerning its commitment to both the environment and the broader topic of social responsibility. The Company has continued to publish a sustainability report (which was renamed the ESG Report in 2022) on an annual basis. In November 2023, the Company published its 2023 ESG Report, detailing the Company’s efforts to address its environmental impact and uphold its social responsibilities in 2023. See Item 1A, Risk Factors – The effects of climate change could harm the Company’s business, for more information on the potential significance of climate change legislation. See also Note 18 in the Notes to the Consolidated Financial Statements for financial information about geographic areas.
