------

breadth of product line, customization capabilities, price, customer support, online capabilities and the ability to meet the special and local needs of our customers.

Competition is driven not only by the product quality and purity across industries we serve, but also by the adaptability of the supplier as a developmental and commercial partner. We rely on our scale, expertise, deep customer access, depth of product and value-added service offerings, marketing strategies and sales force, acquisition strategy, financial profile and management team to deliver superior solutions to our customers and provide extensive market channel access to our suppliers.

**Sustainability**

Our Science for Goodness sustainability platform enhances our approach for creating long-term stakeholder value by embedding sound environmental and corporate responsibility practices into our operations and business strategy. The platform also enables us to regularly measure and report progress on relevant sustainability metrics and goals.

Our approach to sustainability is reflected in our people, the products we create, the transformative services we provide, and the integrity with which we serve our stockholders, business partners, suppliers, customers, associates, and communities. Our strategy includes programs to monitor, measure, and reduce greenhouse gas emissions, efficiently manage resource use, and reduce end of life impact of products. We directly engage our supply chain on these efforts through Avantor's Responsible Supplier Program. The program enables collaboration with supplier partners to identify challenges and solutions focused on four priority topic areas: climate change, human rights, resource circularity, and natural resource conservation.

In 2025, Avantor received several important accolades for our efforts. For a third consecutive year, we received a Bronze Medal from EcoVadis, a leader in sustainability ratings, and were also recognized for the second time as a "Best Place to Work for Disability Inclusion" by Disability:IN.

**Employees and human capital resources**

Our success depends on our ability to attract, retain and motivate highly qualified and diverse talent. As of December 31, 2025, we had approximately 13,500 employees located in over 30 different countries in a variety of roles. Approximately 4,800 of our associates were employed in the U.S. We believe that our relations with our employees are good. As of December 31, 2025, approximately 5% of our employees in North America were represented by unions, and a majority of our employees in Europe were represented by workers' councils or unions. We compete in the highly competitive life sciences industry. Attracting, developing and retaining talented people in technical, marketing, sales, research and other positions is crucial to executing our strategy and our ability to compete effectively. Our ability to recruit and retain such talent depends on a number of factors, including a positive and inclusive work environment and culture, compensation and benefits, talent development and career growth and opportunities, and protecting the health, safety and well-being of our associates. To that end, we invest in our associates in order to be an employer of choice. Our associates reflect the communities in which we live and work, the customers we serve, and possess a broad range of thought and experiences that have helped Avantor achieve our goal of setting science in motion to create a better world.

*People & culture*

Enhancing our Associate Experience is a strategic priority for Avantor. Our values give our associates a foundation for how we want to work together. Innovation, Customer-centricity, Accountability, Respect, and Excellence are the building blocks of our inclusive company culture and send a strong message to our associates, customers, suppliers, stockholders and communities: ICARE. In addition, our executive

------

leaders serve as sponsors of our Associate-Centric Teams (ACTs) in support of our belonging and engagement initiatives. ACTs are employee resource groups that foster an inclusive work environment, build connections, create community, and promote career opportunities. Based on common interests, backgrounds or characteristics, ACTs are open to all associates. Additionally, Avantor's Talent Philosophy is a part of commitment to our associates and guides our managers in their role in supporting our people and our culture.

*Compensation and benefits*

We are committed to rewarding, supporting and developing the associates who make it possible to deliver on our strategy. To that end, we offer a comprehensive total rewards program aimed at the varying health, home-life and financial needs of our diverse global associates. Our total rewards package includes market-competitive pay, broad-based stock grants and bonuses, healthcare benefits, retirement savings plans, an employee stock purchase plan, paid time off and family leave, flexible work schedules, access to wellness programs, free physicals and flu vaccinations, and an Employee Assistance Program and other mental health services.

*Growth and development*

We invest significant resources to develop talent with the right capabilities to deliver the growth and innovation needed to support our strategy. We offer associates and their managers numerous tools to help in their personal and professional development, including our Avantor Career Hub which enables associates to highlight their skills, capture development plans, make connections and find new opportunities inside Avantor. We have a robust portfolio of learning solutions that can be accessed in multiple formats and available to our global associates across various professional, personal and leadership development areas. Each year, we host a Learning & Career week program which is available to associates at all levels globally, and includes a diverse slate of learning opportunities, live sessions and on-demand resources designed to support the personal and professional growth and success of associates. In addition, we provide programs on the Avantor Business System, which drives excellence in people, processes and problem solving. These consistent lean leadership practices empower associates to continuously improve and add value to our operations and customer solutions. We have aligned our performance management system through which 100% of our associates receive annual performance reviews, to support our culture of feedback to increase the focus on continuous learning and development.

*Health, safety and well-being*

We are committed to protecting the health, safety and well-being of our associates. Our approach involves environment, health and safety professionals and process engineers who identify risks and implement behavioral solutions to prevent accidents before they occur. A robust auditing program is in place at every facility to ensure that we measure performance and drive continuous improvement. Our primary focus is to keep associates safe and free from injury. We do this through compliance with regulatory and international requirements, active monitoring of regulatory agencies for changing requirements, partnering with operational leaders to meet Environment, Health & Safety, Security & Sustainability (EHSSS) requirements, and promoting effective communication throughout the organization.

**Intellectual property**

We rely on intellectual property rights, nondisclosure and other contractual provisions and technical measures to protect our offerings, services and intangible assets. Much of our intellectual property is know-how and asset configurations that we treat as trade secrets. These proprietary rights are important to our ongoing operations. In some instances, we may license our technology to third parties or may elect to license intellectual property from others. We have applied in the United States and certain foreign

------

countries for registration of a number of trademarks, service marks and patents, some of which have been registered and issued. We also hold common law rights in various trademarks and service marks. Other than our Avantor, VWR, J.T. Baker, NuSil and Masterflex trademarks, we do not consider any particular patent, trademark, license, franchise or concession to be material to our overall business.

**Government contracts** 

We conduct business with various government agencies and government contractors. As such, we are subject to certain laws and regulations applicable to companies doing business with the government, as well as with those concerning government contracts. Failure to address or comply with these laws and regulations could harm our business by leading to a renegotiation of profits or termination of the contract at the election of the government agency. For a discussion of risks related to government contracting requirements, refer to Part I, Item 1A, "Risk factors." No government contract is of such a magnitude as to have a material adverse effect on our financial results.

**Government regulation**

Our facilities that engage in the manufacturing, packaging, distribution of material used in biopharmaceutical and biomaterials production, as well as many of our products themselves, are subject to extensive ongoing regulation by U.S. governmental authorities, the EMA and other global regulatory authorities. Certain of our subsidiaries are required to register with these agencies, or to apply for permits and/or licenses with, and must comply with the operating, cGMP, quality and security standards of applicable domestic and foreign regulators, including the FDA, the DEA, the Bureau of Alcohol, Tobacco, Firearms and Explosives, DHHS, the equivalent agencies of EU member states, and comparable foreign, state and local agencies, as well as various accrediting bodies, each depending upon the type of operation and the locations of storage or sale of the products manufactured or services provided by those subsidiaries in the event of noncompliance.

In order to maintain certain certifications of quality and safety standards for our manufacturing facilities and operations, we must comply with numerous regulatory systems, standards, guidance and other requirements, as appropriate, including, but not limited to, ICH Q7, the guidelines of the International Pharmaceutical Excipients Council, European in vitro diagnostic medical device directives, U.S. Pharmacopeia / National Formulary, as well as the European, British, Japanese, Indian and Chinese Pharmacopeia, the Food Chemicals Codex and controlled substances regulations.

In addition, our operations, and some of the products we offer, are subject to a number of complex and stringent laws and regulations governing the production, handling, transportation and distribution of chemicals, drugs and other similar products. We are subject to various federal, state, local, foreign and transnational laws, regulations and recommendations, both in the U.S. and abroad, relating to safe working conditions, good laboratory and distribution practices, and the safe and proper use, transportation and disposal of hazardous or potentially hazardous substances. In addition, U.S. and international import and export laws and regulations, including those enforced by the U.S. Departments of Commerce, State and Treasury, OFAC and BIS, require us to abide by certain standards relating to the cross-border transit of finished goods, raw materials and supplies and the handling of related information. Our logistics activities must comply with the rules and regulations of the U.S. Department of Transportation, Department of Homeland Security, Department of Commerce, Department of Defense, and the Federal Aviation Administration and similar foreign agencies. We are also subject to various other laws and regulations concerning the conduct of our foreign operations, including the FCPA and other anti-bribery laws as well as laws pertaining to the accuracy of our internal books and records.

------

The costs associated with complying with the various applicable federal, state, local, foreign and transnational regulations could be significant, and the failure to comply with such legal requirements could have an adverse effect on our reputation, results of operations and financial condition. See Part I, Item 1A, "Risk factors—Risks related to regulation." We are subject to audits by the FDA and other similar foreign regulatory bodies. To date, we have had no instances of noncompliance that have had a material impact on our operations.

In addition to the regulations described above, as part of our aerospace and military offerings, we are registered with the DDTC as a manufacturer and exporter of goods controlled by ITAR, and we are subject to strict export control and prior approval requirements related to these goods. In connection with our NuSil brand products, we have one ITAR site registration and one ITAR product registration, and we maintain control systems which enable ITAR compliance. With respect to our electronic materials products, we adhere to applicable industry guidelines which set stringent quality criteria for our products, and we are subject to import and export regulations and other restrictions regarding the safe use of these products as well.

We are also subject to various federal, state and international laws and regulations related to privacy and data protection, including the EU's GDPR as well as the California Consumer Privacy Act of 2018, which became effective on January 1, 2020 (as amended by the California Privacy Rights Act, which took effect on January 1, 2023, the "CPRA"). The interpretation and application of data privacy, cross-border data transfers and data protection laws and regulations are often uncertain and are evolving in the U.S. and internationally, such as in the EU, China and other jurisdictions. We monitor pending and proposed legislation and regulatory initiatives to ascertain their relevance to, and potential impact on, our business and develop strategies to address regulatory trends and developments, including any required changes to our privacy and data protection compliance programs and policies. Globally, we see a growing trend toward data protection laws and regulations increasing in complexity and number, and we anticipate that our obligations will expand commensurately.

**Environmental matters**

We are subject to various laws and governmental regulations concerning environmental, safety and health matters, including employee safety and health, in the U.S. and other countries. U.S. federal environmental legislation that affects us includes the Toxic Substances Control Act, the Resource Conservation and Recovery Act, the Clean Air Act, the Clean Water Act, the Safe Drinking Water Act, and CERCLA. These laws and regulations govern, among other things, air emissions, wastewater discharges, the use, handling and disposal of hazardous substances and wastes, soil and groundwater contamination and the general health and safety of our associates and the communities in which we operate. We are also subject to regulation by OSHA concerning employee safety and health matters. The EPA, OSHA, and other federal and foreign or local agencies have the authority to promulgate regulations that may impact our operations.

Under CERCLA, and analogous statutes in local and foreign jurisdictions, current and former owners and operators of contaminated land are strictly liable for the investigation and remediation of the land and for natural resource damages that may result from releases of hazardous substances at or from the property. Liability under CERCLA and analogous laws is strict, unlimited, joint, several, retroactive, may be imposed regardless of fault and may relate to historical activities or contamination not caused by the current owner or operator. It is possible that facilities that we acquire or have acquired may expose us to environmental liabilities associated with historical site conditions that have not yet been discovered.

------

In addition to the federal environmental laws that govern our operations, various states have been delegated certain authority under the aforementioned federal statutes as well as having authority over these matters under state laws. Many state and local governments have adopted environmental and employee safety and health laws and regulations, some of which are similar to federal requirements.

A number of our operations involve, in varying degrees, the handling, manufacturing, use or sale of substances that are or could be classified as toxic or hazardous materials within the meaning of applicable laws. Consequently, some risk of environmental harm is inherent in our operations and products, as it is with other companies engaged in similar businesses. For additional information about environmental matters, see note 13 to our consolidated financial statements beginning on page F-1 of this report.

**Item 1A. Risk factors**

**Risks related to our business and our industry**

***Significant interruptions in our operations could harm our business, financial condition and results of operations.***

Any significant disruptions to the operations of our manufacturing or distribution centers or logistics providers for any reason, including labor relations issues, power interruptions, severe weather, destruction or damage or other circumstances beyond our control could have a significant impact on our operating results, including an increase to our operating expenses without coverage or compensation, or seriously harm our ability to fulfill our customers' orders or deliver products on a timely basis, or both. We must also maintain sufficient production capacity to meet anticipated customer demand, which carries fixed costs that we may not be able to offset if orders slow, which would adversely affect our operating margins. If we are unable to manufacture our products consistently, in sufficient quantities, and on a timely basis, our net sales, gross margins and our other operating results will be materially and adversely affected. In addition, we have experienced problems with, or delays in, our production, shipping and logistics capabilities that have resulted in delays in our ability to ship finished products, and there can be no assurance that we will not encounter such problems in the future. Significant delays in our manufacturing, shipping or logistics processes could damage our customer relationships, cause disruption to our customers and adversely affect our business, financial condition and operating results.

***We have been impacted by supply chain constraints and inflationary pressures***

We have experienced challenges in sourcing certain products and raw materials as a result of global supply chain disruptions and have experienced inflationary pressures across all of our cost categories. While we have implemented pricing and productivity measures to combat these pressures, they may continue to adversely impact our results.

------

***We compete in highly competitive markets. Failure to compete successfully could adversely affect our business, financial condition and results of operations.***

We face competition across our products and the markets in which we operate, both domestically and internationally. Competition is driven by proprietary technologies and know-how, capabilities, consistency of operational performance, quality, supply chain control, price, value and speed. Our competitors range from regional companies, which may be able to more quickly respond to customers' needs because of geographic proximity, to large multinational companies, which may have greater financial, marketing, operational and research and development resources (R&D) than we do, allowing for a more rapid response with new, alternative or emerging technologies. Such actions may increase pricing pressure on us or cause us to lose existing market share. In addition, consolidation trends in the biopharma and healthcare industries have served to create fewer customer accounts and to concentrate purchasing decisions for some customers, resulting in increased pricing pressures. New competitors in low-cost manufacturing locations, particularly developing markets, may create increased pricing and competitive pressures and impede our goal to grow in those markets. Failure to anticipate and respond to competitors' actions may adversely affect our results of operations and financial condition.

***It may be difficult for us to implement our strategies for improving growth and optimizing costs.***

Effective January 1, 2024, we transitioned to a new operating model consisting of two complementary business segments, the Laboratory Solutions segment and the Bioscience Production segment. In conjunction with our new operating model, we launched a multi-year cost transformation initiative, with the objective to deliver approximately $300 million in annual gross run-rate savings by the end of 2026. We have expanded this initiative and now expect to generate approximately $400 million in run rate gross savings by the end of 2027. We have also committed to certain significant restructuring activities in connection with the initiative. The initiative and restructuring activities are subject to a variety of known and unknown risks and uncertainties, including the potential that we may not be able to successfully execute on the initiative or achieve the anticipated benefits and cost-saving opportunities, or that achieving such benefits and opportunities may take longer to realize than expected. If we are unable to achieve the expected benefits from the initiative and manage the effects of the restructuring activities, this could have an adverse effect on our business, results of operations and financial condition.

As we continue to refine our business model, we may also pursue divestitures in line with our new operating model. Our ability to manage our business and conduct our global operations while also pursuing our strategies for improving growth and optimizing costs requires considerable management attention and resources and is subject to the challenges of supporting a rapidly growing business in an environment with varying cultural, commercial, legal and regulatory frameworks. Our failure to implement these strategies in a cost-effective and timely manner could have an adverse effect on our business, results of operations and financial condition.

***Part of our growth strategy is to pursue strategic acquisitions, which will subject us to a variety of risks that could harm our business.***

As part of our business strategy, we may pursue and complete selective acquisition opportunities. There can be no assurances that we will be able to complete suitable acquisitions for a variety of reasons, including the identification of, and competition for, acquisition targets, the need for regulatory approvals, the inability of the parties to agree to the structure or purchase price of the transaction and the inability to finance the transaction on commercially acceptable terms. In addition, any completed acquisition will subject us to a variety of other risks, including: (i) potential adverse effects on our business relationships with existing or future suppliers and other business partners (in particular, to the extent we consummate acquisitions that vertically integrate portions of our business); (ii) the assumption of substantial actual or contingent liabilities, known or unknown, including environmental liabilities; (iii) failure to meet

------

expectations of future financial performance; (iv) delays or reductions in realizing expected synergies; (v) substantial unanticipated costs or other problems associated with acquired businesses or devoting time and capital to investigate a potential acquisition that is not completed; (vi) failure to achieve intended objectives for a transaction; (vii) failure to retain key personnel, customers and suppliers of the acquired business; and (viii) adverse impacts resulting from impairment charges on goodwill, other intangible assets and tangible assets. These factors related to our acquisition strategy, among others, could have an adverse effect on our business, financial condition and results of operations.

***The customers we serve have experienced, and will continue to experience, significant industry-related changes that could adversely affect our business.***

Many of the customers we serve have experienced, and are expected to continue to experience, significant industry-related changes, including reductions in governmental funding or payments for biopharmaceutical products, expirations of significant patents, adverse changes in legislation or regulations regarding the delivery or pricing of general healthcare services or mandated benefits, and increased requirements on quality. General industry changes include: (i) development of large and sophisticated group purchasing organizations and on-line auction sites that increase competition for, and reduce spending on, laboratory products; (ii) consolidation of biopharmaceutical companies resulting in a rationalization of research expenditures; (iii) increased regulatory scrutiny over drug production requiring safer raw materials; (iv) customers' purchasing the products that we supply directly from our suppliers; and (v) significant reductions in development and production activities.

Some of our customers have implemented, or may in the future implement, certain measures described above in an effort to control and reduce costs. The ability of our customers to develop new products to replace sales decreases attributable to expirations of significant patents, along with the impact of other past or potential future changes in the industries we serve, may result in our customers significantly reducing their purchases of products from us or the prices they are willing to pay for those products. While we believe we will be able to adapt our business to maintain existing customer relationships and develop new customer relationships, if we are unsuccessful or untimely in these efforts, our results of operations may suffer.

***Reductions in customers' research budgets or government funding may adversely affect our business.***

Many of our customers are universities, government research laboratories, private foundations and other institutions that are dependent on grants from government agencies, such as the NIH, for funding. R&D spending by our customers may fluctuate based on spending priorities and general economic conditions. The level of government funding for R&D is unpredictable. Reductions or delays in governmental spending could cause customers to delay or forego purchases of our products. If government funding necessary for the purchase of our products were to decrease, our business and results of operations could be adversely affected. Spending by some of these customers fluctuates based on budget allocations and the timely passage of the annual federal budget. An impasse in federal government budget decisions could lead to substantial delays or reductions in federal spending.

***Our offerings are highly complex, and, if our products do not satisfy applicable quality criteria, specifications and performance standards, we could experience lost sales, delayed or reduced market acceptance of our products, increased costs and damage to our reputation.***

The high-purity materials and customized solutions we offer are highly exacting and complex due to demanding customer specifications and stringent regulatory and industry requirements. Our operating results depend on our ability to execute and, when necessary, improve our global quality control systems, including our ability to effectively train and maintain our employees with respect to quality control. A

------

failure of our global quality control systems could result in problems with facility operations or preparation or provision of defective or non-compliant products. Nearly all of our products are subsequently incorporated into products sold to end users by our customers, and we have no control over the manufacture and production of such products. Our success depends on our customers' confidence that we can provide reliable, high-quality products. We believe that customers in our target markets are likely to be particularly sensitive to product defects and errors. Our reputation and the public image of our products and technologies may be impaired if our products fail to perform as expected or fail to meet applicable quality criteria, specifications or performance standards. If our products experience, or are perceived to experience, a material defect or error, this could result in loss or delay of net sales, damaged reputation, diversion of development resources, and increased insurance or warranty costs, any of which could harm our business.

***The loss of a significant number of customers or a significant reduction in customer orders could reduce our net sales and harm our operating results.***

Our operating results could be negatively affected by the loss of revenue from a significant number of our customers, including direct distributors and end users. Though we often include pricing and volume incentives in our contracts, our customers are generally not obligated to purchase any fixed quantities of products, and they may stop placing orders with us at any time. If we experience a significant reduction in customer orders, increased order deferrals, our sales could decline, and our operating results may not meet our expectations. In addition, if customers order our products, but fail to pay on time or at all, our liquidity and operating results could be adversely affected.

Our contracts generally do not contain minimum purchase requirements, and we sell primarily on a purchase order basis. Therefore, our sales are subject to changes in demand from our customers, and these changes have been material in the past. The level and timing of orders placed by our customers vary for a number of reasons, including individual customer strategies, the introduction of new technologies, the desire of our clients to reduce their exposure to any single supplier and general economic conditions. If we are unable to anticipate and respond to the demands of our customers, we may lose customers because we have an inadequate supply of raw materials with which to manufacture our products or insufficient capacity in our sites. Alternatively, we may have excess inventory or excess capacity. Either of these factors may have a material adverse effect on our business, financial position and operating results.

***We are subject to risks associated with doing business globally, which may harm our business.***

We have global operations and derive a substantial portion of our net sales from customers outside of the United States. Accordingly, our international operations or those of our international customers could be substantially affected by a number of risks arising from operating an international business, including: (i) limitations on repatriation of earnings; (ii) taxes on imports; (iii) the possibility that unfriendly nations or groups could boycott our products; (iv) general economic and political conditions in the markets where we operate, including changes in inflation and interest rates, instability in the global banking industry, rising energy prices, potential energy shortages and actual or anticipated military or political conflicts, such as the ongoing Ukraine/Russia or Israel/Hamas conflicts; (v) foreign currency exchange rate fluctuations; (vi) escalation of geopolitical tensions or potential changes in diplomatic and trade relationships, including potential changes to trade restrictions, tariffs and exchange controls and political and trade uncertainty in China along with potential retaliatory tariffs by other countries; (vii) a global health crisis; (viii) potential increased costs associated with overlapping tax structures; (ix) potential increased reliance on third parties within less developed markets; (x) more limited protection for intellectual property rights in some countries; (xi) difficulties and costs associated with staffing and managing foreign operations; (xii) difficulties in complying with a wide variety of foreign laws and regulations and unexpected changes thereto and costs associated with compliance; (xiii) expanded

------

enforcement of laws related to data protection and personal privacy; (xiv) the risk that certain governments may adopt regulations or take other actions that would have a direct adverse impact on our business and market opportunities, including nationalization of private enterprise; (xv) violations of anti-bribery and anti-corruption laws, such as the FCPA; (xvi) violations of economic sanctions laws, such as the regulations enforced by OFAC; (xvii) longer accounts receivable cycles in certain foreign countries, whether due to cultural differences, exchange rate fluctuation or other factors; (xviii) the credit risk of local customers and distributors; (xix) limitations on our ability to enforce legal rights and remedies with third parties or partners outside of the United States; (xx) import and export licensing requirements and other restrictions, such as those imposed by OFAC, BIS, DDTC and comparable regulatory agencies and policies of foreign governments; and (xxi) changes to our distribution networks.

***Changes in exchange rates can adversely affect our financial condition, results of operations and cash flows.***

A substantial amount of our revenues is derived from international operations, and we anticipate that a significant portion of our sales will continue to come from outside of the United States in the future. Our consolidated results of operations are comprised of many different functional currencies that translate into our U.S. dollar reporting currency. The movement of the U.S. dollar against those functional currencies, particularly the Euro, has caused significant variability in our results in the past and may continue to do so in the future. The revenues we report with respect to our operations outside of the United States have been in the past and may be adversely affected by fluctuations in foreign currency exchange rates.

Further, we have a substantial amount of Euro denominated indebtedness, as well as intercompany loans and short-term intercompany balances with the Euro as their functional currency. Fluctuations in the exchange rate between U.S. dollars and Euros may have a material adverse effect on our ability to repay such indebtedness. See Part I, Item 7A, "Quantitative and qualitative disclosures about market risk."

***Our business depends on our ability to use and access information systems, and any failure to successfully maintain these systems or implement new systems to handle our changing needs could materially harm our operations.***

Our businesses rely on sophisticated information systems: (i) to obtain, rapidly process, analyze, and manage data to facilitate the purchase and distribution of thousands of inventory items from numerous distribution centers; (ii) to receive, process, and ship orders on a timely basis; (iii) to account for other product and service transactions with customers; (iv) to manage the accurate billing and collections for thousands of customers; and (v) to process payments to suppliers. We continue to make substantial investments in data centers and information systems. To the extent our information systems are not successfully implemented or fail, or there are data center interruptions or outages, our business and results of operations may be adversely affected. Our business and results of operations may also be adversely affected if a third-party service provider does not perform satisfactorily, or if the information systems are interrupted or damaged by unforeseen events, including due to the actions or inactions of third parties.

While we have implemented cybersecurity and data protection measures, our efforts to minimize the risks and impacts of cyberattacks and protect our information systems may be insufficient and we may experience significant breaches or other failures or disruptions that could compromise our systems and data and, ultimately, affect our business operations and our financial position or results of operations. New technology that could result in greater operational efficiency, such as the development and adoption of AI and machine learning technology, may further expose our systems and businesses to the risk of cyberattacks. Like other companies, the systems and networks we maintain and third party systems and networks we use have in the past been, and will likely in the future be, subject to or targets of

------

unauthorized or fraudulent access, including physical or electronic break-ins or unauthorized tampering, as well as attempted cyber and other security threats and other attacks such as "denial of service" attacks, phishing, untargeted but sophisticated and automated attacks, ransomware, and other disruptive software. We are also exposed to similar risks resulting from cyberattacks that are experienced by our third-party service providers. For example, we and many of the third-party service providers we rely on use generative AI, which increases the risk that our confidential or proprietary information or personal data could be inadvertently or maliciously exposed. Security breaches can also occur as a result of intentional or inadvertent actions by our employees, third-party service providers or their personnel or other parties.

A failure, interruption, or breach of our systems, or those of our third-party service providers, as a result of cyber-attacks or information security breaches, could disrupt our business, result in the disclosure or misuse of confidential or proprietary information or personal data, damage our reputation, cause loss of customers or revenue, increase our costs, result in litigation and/or regulatory action, and/or cause other losses, any of which may have a material adverse impact on our business operations and our financial position or results of operations. Although we believe that we have robust information security procedures, controls and other safeguards in place, as cyber threats continue to evolve, we will be required to expend additional resources to continue to enhance our information security measures and/or to investigate and remediate information security vulnerabilities.

***Our actual or perceived failure to adequately protect personal data could adversely affect our business.***

Given the nature of our business, we collect and store confidential information that customers provide in order to, among other things, purchase products and services and register on our website. We are required to comply with increasingly complex and changing data privacy regulations both in the United States and beyond that regulate the collection, use, sharing, and transfer of personal data. Many of these regulations also grant rights to individuals. Many foreign data privacy regulations (including GDPR in the EU) and certain state laws and regulations (including California's CPRA) impose requirements beyond those enacted under federal law including, in some instances, private rights of action. We are also required to comply with expanding and increasingly complex privacy and data protection regulations in the United States and abroad with respect to reporting adverse events and additional requirements for avoiding or responding to an adverse event. We also have contractual obligations to our customers related to the protection of personal data and compliance with privacy laws.

While we have taken various measures and made significant efforts and investment and designed our policies, processes and systems to be robust, a failure, or perceived failure, by us to comply with any applicable regulatory requirements or orders, including but not limited to privacy, data protection, information security, or consumer protection-related privacy laws and regulations, in one or more jurisdictions within the United States, the EU or elsewhere, could result in proceedings or actions against us by governmental entities or individuals; subject us to significant fines, penalties, and/or judgments; require us to change our business practices; limit access to our products and services in certain countries, incur substantial costs (even if we ultimately prevail) or otherwise adversely affect our business.

***Our inability to protect our intellectual property could adversely affect our business. In addition, third parties may claim that we infringe their intellectual property, and we could suffer significant litigation or licensing expenses as a result.***

We rely on a variety of intellectual property rights, including patents, trademarks, copyrights and trade secrets, to protect our proprietary technology and products. We place considerable emphasis on obtaining patent or maintaining trade secret protection for significant new technologies, products and processes because of the length of time and expense associated with bringing new products and processes through development and to the market. We may need to spend significant resources monitoring and enforcing our

------

intellectual property rights and we may not be able to prove infringement by third parties. Our competitive position may be harmed if we cannot enforce our intellectual property rights. In some circumstances, we may choose to not pursue enforcement for business reasons. In addition, competitors might avoid infringement by designing around our intellectual property rights or by developing non-infringing competing technologies. Intellectual property rights and our ability to enforce them may be unavailable or limited in some countries, which could make it easier for competitors to capture market share and could result in lost revenues.

***Our trademarks are valuable assets and if we are unable to protect them from infringement, our business prospects may be harmed.***

Our brands, particularly our J.T. Baker, NuSil, VWR and Masterflex brands, are valuable assets. Therefore, we actively manage our trademark portfolio, including by maintaining registrations for long-standing trademarks and applying to obtain trademark registrations for new brands. We also police our trademark portfolio against infringement. Our efforts to protect and defend our trademarks may be unsuccessful against competitors or other third parties for a variety of reasons. To the extent that third parties or distributors sell products that are counterfeit versions of our branded products, our customers could inadvertently purchase products that are inferior. This could cause our customers to refrain from purchasing our brands in the future and in turn could impair our brand equity and adversely affect our sales.

***We are subject to product liability and other claims in the ordinary course of business.***

Our business involves risk of product liability, intellectual property claims and other claims in the ordinary course of business arising from the products that we source from various manufacturers or produce ourselves. Furthermore, there may be product liability risks that are unknown or which become known in the future. Substantial, complex or extended litigation on any claim could cause us to incur significant costs and distract our management. We maintain insurance policies and in some cases, our suppliers, customers and predecessors of acquired companies have indemnified us against certain claims. We cannot assure you that our insurance coverage or indemnification agreements will be available in all pending or any future cases brought against us. Accordingly, we could be subject to uninsured and unindemnified future liabilities requiring us to provide additional reserves to address such liabilities. An unfavorable result in a case for which adequate insurance or indemnification is not available could adversely affect our business, financial condition and results of operations.

***We must develop new products, adapt to rapid and significant technological change and respond to introductions of new products by competitors to remain competitive.***

We sell our products in industries that are characterized by significant technological changes, frequent new product and technology introductions and evolving industry standards. As a result, our customers' needs are rapidly evolving. If we do not appropriately innovate and invest in new technologies, our offerings may become less desirable in the markets we serve, and our customers could move to new technologies offered by our competitors or make products themselves. Without the timely introduction of new products, services and enhancements, our offerings will likely become less competitive over time, in which case, our competitive position, net sales and operating results could suffer. To the extent we fail to timely introduce new and innovative products or services, adequately predict our customers' needs or fail to obtain desired levels of market acceptance, our business may suffer.

------

Accordingly, we focus significant efforts and resources on the development and identification of new technologies, products and services that are attractive to, and gain acceptance, in the markets we serve and further broaden our offerings. We have been and expect to continue to utilize AI and machine learning in certain of our products and services. As with many technological innovations, there are significant risks and challenges involved in maintaining and deploying these technologies, including risks related to cybersecurity, privacy and data use practices as well as related to accuracy issues, and there can be no assurance that the use of such technologies will enhance our products or services or be beneficial to our business. Further, the regulatory landscape surrounding AI is evolving and may impose restrictions that limit the usability or effectiveness of AI in our products and services and expose us to an increased risk of regulatory enforcement and litigation.

***We depend upon the availability of raw materials.***

Our operations depend upon our ability to obtain high-quality raw materials meeting our specifications and other requirements at reasonable prices, including various active pharmaceutical ingredients, components, compounds, excipients and other raw materials, many of which are sole-sourced due to market or customer demands. Our ability to maintain an adequate supply of such materials could be impacted by the availability and price of those raw materials and maintaining relationships with key suppliers.

Moreover, we are dependent upon the ability of our suppliers to provide materials and components that meet our specifications, quality standards, other applicable criteria, and delivery schedules. Our suppliers' failure to provide expected raw materials or components that meet such criteria could adversely affect production schedules and contract profitability and negatively impact our results of operations.

***We depend upon maintaining our relationships with suppliers.***

We offer products from a wide range of suppliers. While there is generally more than one source of supply for most of the categories of third-party materials & consumables and equipment & instrumentation that we sell, we currently do not manufacture the majority of our products and are dependent on these suppliers for access to those products. Our ability to sustain our gross margins has been, and will continue to be, dependent in part upon our ability to obtain favorable terms from our suppliers. These terms may change from time to time, and such changes could adversely affect our gross margins over time. In addition, our results of operations and cash flows could be adversely impacted by the acceleration of payment terms to our suppliers and/or the imposition of more restrictive credit terms and other contractual requirements.

***Our use of chemicals and chemical processes is subject to inherent risk.***

We use chemical ingredients in the manufacture of certain of our products. Due to the nature of the manufacturing process itself, there is a risk of incurring liability for damages caused by or during the storage or manufacture of both the chemical ingredients and the finished products. The processes used in certain of our facilities typically involve large volumes of solvents and chemicals, creating the potential for fires, spills and other safety or environmental impacts. If any of these risks materialize, it could result in significant remediation and other costs, potential adverse regulatory actions and liabilities, any of which could have an adverse effect on our business, results of operations and financial condition.

In addition, the manufacturing, use, storage, and distribution of chemicals are subject to threats including terrorism. We have several high-risk chemical facilities that contain materials that could be stolen and used to make weapons. We could also be subject to an attack on our high-risk facilities that could cause a

------

significant number of deaths and injuries. Such an occurrence could also harm the environment, our reputation and disrupt our operations.

***Climate change, and the legal or regulatory response thereto, may have a long-term impact on our business, financial condition and results of operations.***

We continue to focus on strategies and systems, such as reducing greenhouse gas emissions and packaging waste, to address climate change. However, we face climate and environmental risks and the occurrence of one or more unexpected events, including fires, tornadoes, tsunamis, hurricanes, earthquakes, drought, storms, sea level rise, floods, and other severe hazards or accidents in countries or regions in which we operate could adversely affect our operations and financial performance. The effects of climate change and legal or regulatory initiatives to address climate change could have a long-term adverse impact on our business, financial condition and results of operations. We also monitor rules and regulations related to sustainability and corporate responsibility disclosure obligations, which may expose us to increased costs associated with additional reporting obligations. In addition, we have established and publicly announced goals and commitments to reduce our carbon footprint, including targets to reduce greenhouse gas emissions (scope 1, scope 2 and scope 3). If we are unable to achieve, or improperly report on our progress toward, our carbon footprint reduction goals and commitments, this may result in litigation and/or regulatory action as well as negative publicity, which could lead to the loss of business, adverse reputational impacts, diluted market valuations and challenges in attracting and retaining customers and talented employees.

We also face increasing attention from investors, regulators, and other stakeholders, who may have conflicting views related to our positions, performance, and disclosures relating to sustainability and corporate responsibility-related matters, and the legal and regulatory landscape continues to evolve and may result in conflicting requirements and expectations. If we draw scrutiny for the positions we take or do not take on these matters (or for altering any such position) or receive unfavorable ratings from third-party organizations that provide information to investors on such matters, it could be used by investors, lenders, customers, employees and other stakeholders to inform their investment, financing, purchasing or employment decisions, which could have a negative impact on our business. Additionally, a failure to adequately meet regulatory expectations may result in non-compliance, the loss of business and reputational impacts, and we may become the target of litigation or investigations initiated by government authorities or private actors alleging that our activities related to these matters are anti-competitive, discriminatory or otherwise unlawful.

***We are highly dependent on our senior management and key employees.***

Our success depends on our ability to attract, motivate and retain highly qualified individuals. Competition for senior management and other key personnel in our industry is intense, and the pool of suitable candidates is limited. We have recently experienced changes in our senior management. The inability to identify, attract, retain and properly motivate members of our senior management team and other key employees, or to find suitable replacements for them could have a negative effect on our operating results. Additionally, changes in our organization as a result of senior management and board transitions, which we have recently experienced, may have a disruptive impact on our ability to implement our strategy and could negatively affect our business and financial condition.

***The indemnification provisions of acquisition agreements by which we have acquired companies may not fully protect us and as a result, we may face unexpected liabilities.***

Certain of the acquisition agreements by which we have acquired companies require the former owners to indemnify us against certain liabilities related to the operation of the company before we acquired it. In most of these agreements, however, the liability of the former owners is limited and certain former

------

owners may be unable to meet their indemnification responsibilities. We cannot assure you that these indemnification provisions will protect us fully or at all, and as a result, we may face unexpected liabilities that adversely affect our financial statements.

***We face risks related to health epidemics and pandemics.***

We face risks related to health epidemics and pandemics, including risks related to any responses thereto by the federal, state or foreign governments, as well as customers and suppliers. A pandemic has in the past and could in the future adversely affect our operations, supply chains and distribution network, and we could experience and expect prolonged unpredictable reductions in supply and demand for certain of our offerings similar to those experienced during the COVID-19 pandemic, as well as unpredictable increases in demand for certain of our offerings similar to those experienced during the COVID-19 pandemic. Further, it is possible that disruptions or delays in shipments of certain raw materials used in the products we manufacture and in the finished goods that we sell globally could be similar to those experienced during the COVID-19 pandemic. Any extended disruption in our ability to service our customers could have a negative effect on our operating results.

***Changes in tax law relating to multinational corporations could adversely affect our tax position.***

The U.S. Congress, foreign governments, and their agencies in non-U.S. jurisdictions where we and our affiliates do business, and the Organization for Economic Cooperation and Development ("OECD"), continue to focus on issues related to the taxation of multinational corporations. As part of this focus, the OECD has introduced a framework to implement a 15% global minimum corporate tax rate. Certain countries in which we operate have adopted legislation and other countries are in the process of introducing legislation to implement the minimum tax directive. While we do not currently expect the minimum tax directive to have a material impact on our effective tax rate, our analysis is ongoing as the OECD continues to release additional guidance. There can be no assurance that these changes, and any further contemplated changes when finalized and adopted by countries, will not have an adverse impact on our provision for income taxes. Additionally, on July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted, introducing broad changes to the U.S. tax code, including modifications to corporate and international tax provisions. As a result of OBBBA, our current cash tax obligations were reduced by approximately $43.0 million due to changes to several provisions, including the reinstatement of immediate expensing for domestic R&D expenditures, the extension of 100% bonus depreciation for qualified properties and the relaxation of limitations on the deductibility of business interest expense. The impact on income tax expense resulting from OBBBA was immaterial.

Due to the potential for changes to tax laws and regulations or changes to the interpretation thereof, the ambiguity of tax laws and regulations, the subjectivity of factual interpretations, the complexity of our intercompany arrangements, uncertainties regarding the geographic mix of earnings in any particular period, and other factors, our estimates of effective tax rate and income tax assets and liabilities may be incorrect and our financial statements could be adversely affected. The impact of the factors referenced in the first sentence of this paragraph may be substantially different from period-to-period.

***Certain of our businesses rely on relationships with collaborative partners and other third parties for development, supply and marketing of certain products and potential products, and such collaborative partners or other third parties could fail to perform sufficiently.***

We believe that for certain of our businesses, success in penetrating target markets depends in part on their ability to develop and maintain collaborative relationships with other companies. Relying on collaborative relationships is risky because, among other things, our collaborative partners may (i) not devote sufficient resources to the success of our collaborations; (ii) fail to obtain regulatory approvals necessary to continue the collaborations in a timely manner; (iii) be acquired by other companies and

------

terminate our collaborative partnership or become insolvent; (iv) compete with us; (v) disagree with us on key details of the collaborative relationship; (vi) have insufficient capital resources; and (vii) decline to renew existing collaborations on acceptable terms. Because these and other factors may be beyond our control, the development or commercialization of our products involved in collaborative partnerships may be delayed or otherwise adversely affected. If we or any of our collaborative partners terminate a collaborative arrangement, we may be required to devote additional resources to product development and commercialization or we may need to cancel some development programs, which could adversely affect our business and financial statements.

**Risks related to regulation**

***We are required to comply with a wide variety of laws and regulations, and are subject to regulation by various federal, state and foreign agencies, and our failure to comply with existing and future regulatory requirements could adversely affect our results of operations and financial condition.***

We compete in markets in which we and our customers are subject to federal, state, local, international and transnational laws and regulations, including the operating, quality and security standards of the FDA, various state health departments, the DHHS, similar bodies of the EU and its member states and other comparable agencies around the world, and, in the future, any changes to such laws and regulations could adversely affect us. We develop, configure and market our products to meet customer needs driven by those regulations. Among other rules affecting us, we are subject to laws and regulations concerning cGMP and product safety. Our subsidiaries may be required to register for permits and/or licenses with, and may be required to comply with, the laws and regulations of the FDA, the DHHS, the DEA, foreign agencies including the EMA, and other various state health departments and/or comparable state and foreign agencies as well as certain accrediting bodies depending upon the types of operations and locations of distribution and sale of the products manufactured or services provided by those subsidiaries. Any significant change in regulations could reduce demand for our products or increase our expenses. For example, many of our products are marketed to the biopharma industry for use in discovering, developing and manufacturing drugs, or are sold as raw materials or components to drug device manufacturers or for use in the manufacture of implantable devices. Changes in the domestic or foreign regulation of drug discovery, development or manufacturing processes or medical device manufacturing processes, or adverse findings concerning any health effects associated with these products, could have an adverse effect on the demand for these products and could also result in legal liability and claims.

We are also registered with the DDTC, as a manufacturer and exporter of goods controlled by ITAR, and we are subject to strict export control and prior approval requirements related to these goods. Our failure to comply with ITAR and other export control laws and regulations, as well as economic sanctions, could result in penalties, loss, or suspension of contracts or other consequences. Any of these could adversely affect our operations and financial condition. Failure by us or by our customers to meet one or more of these various regulatory obligations could have adverse consequences in the event of material non-compliance. Compliance with relevant sanctions and export control laws could restrict our access to, and increase the cost of obtaining, certain products and at times could interrupt our supply of imported inventory or our ability to service certain customers. Conversely, compliance with these regulatory obligations may require us to incur significant expenses.

In addition, certain of our facilities are certified to ISO, including ISO 13485, ISO 9001, AS9100, ISO 22000 and/or ISO 14001. These standards are voluntary quality management system standards, the maintenance of which indicates to customers certain quality and operational norms. Customers may rely on contractual assurances that we make with respect to ISO certificates to transact business. Failure to comply with these ISO standards can lead to observations of non-compliance or even suspension of ISO

------

or Aerospace Standard (AS) certifications or European Community (EC) Declarations of Conformity Certificates by the registrar. If we were to lose ISO or AS certifications or EC Declarations of Conformity, we could lose sales and customers to competitors or other suppliers. We are also subject to periodic inspections or audits by our customers. If these audits or inspections identify issues or the customer perceives there are issues, the customer may decide to cease purchasing products from us which could adversely affect our business.

***Our reputation, ability to do business and financial statements may be impaired by improper conduct by any of our employees, agents or business partners.***

We cannot provide assurance that our internal controls and compliance systems will always protect us from acts committed by employees, agents or business partners of ours (or of businesses we acquire or partner with) that would violate U.S. and/or non-U.S. laws, including the laws governing payments to government officials, bribery, fraud, kickbacks and false claims, pricing, sales and marketing practices, conflicts of interest, competition, export and import compliance, money laundering and data privacy. In particular, the FCPA, the U.K. Bribery Act and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business, and we operate in many parts of the world that have experienced corruption to some degree. Any such improper actions or allegations of such acts could damage our reputation and subject us to civil or criminal investigations in the United States and in other jurisdictions and related stockholder lawsuits, could lead to substantial civil and criminal, monetary and non-monetary penalties and could cause us to incur significant legal and investigatory fees. In addition, the government in relevant jurisdictions may seek to hold us liable as a successor for violations committed by companies in which we invest or that we acquire. We also rely on our suppliers to adhere to our supplier standards of conduct, and material violations of such standards could occur that could have a material effect on our business, reputation and financial statements.

***We are subject to laws and regulations governing government contracts, and failure to address these laws and regulations or comply with government contracts could harm our business by leading to a reduction in sales to these customers or penalties.***

We sell products to government entities and, as a result, we are subject to various statutes and regulations that apply to companies doing business with the government. The laws governing government contracts differ from the laws governing private contracts and government contracts may contain pricing terms and conditions that are not applicable to private contracts. We are also subject to investigation for compliance with the regulations governing government contracts. A failure to comply with these regulations could result in suspension of these contracts, criminal, civil and administrative penalties or debarment.

***We are subject to environmental, health and safety laws and regulations, and costs to comply with such laws and regulations, or any liability or obligation imposed under such laws or regulations, could negatively impact our business, financial condition and results of operations.***

We are subject to a broad range of foreign, federal, state and local environmental, health and safety laws and regulations, including those of the EPA, OSHA and equivalent local, state, and foreign regulatory agencies in each of the jurisdictions in which we operate, and we may be fined or penalized for non-compliance. In addition, contamination resulting from our current or past operations or from past uses of land that we own or operate may trigger investigation or remediation obligations, which may have an adverse effect on our business, financial condition and results of operations. We cannot be certain that identification of presently unidentified environmental, health and safety conditions, new regulations, more vigorous enforcement by regulatory authorities or other unanticipated events will not arise in the future

------

and give rise to additional environmental liabilities, business interruptions, compliance costs or penalties, which could have an adverse effect on our business, financial condition and results of operations.

We currently incur costs and may incur additional costs related to remediation of alleged environmental damage associated with past or current waste disposal practices or other hazardous materials handling at property that we currently own or operate, or formerly owned or operated, or facilities to which we arranged for the disposal of hazardous substances. Our liabilities arising from past or future releases of, or exposures to, hazardous substances may exceed our estimates or adversely affect our financial statements and reputation and we may be subject to additional claims for cleanup or other environmental claims in the future based on our past, present or future business activities, and we may not be able to recover any costs under any of our indemnifications that we have. For additional information regarding environmental matters, see note 13 to our consolidated financial statements beginning on page F-1 of this report.

***Changes in corporate governance and public disclosure requirements and expectations could impact compliance costs and the risks of noncompliance.***

We are subject to the rules and regulations promulgated by a number of governmental and self-regulatory organizations, including the SEC and NYSE, as well as evolving investor expectations around sustainability and corporate responsibility practices and disclosures. These rules and regulations continue to evolve in scope and complexity, and many new requirements have been created in response to laws and directives enacted by federal, state, local and foreign governments, making compliance more difficult and uncertain. The increasing complexity and costs to comply with such evolving expectations, rules and regulations, as well as any risk of noncompliance, could adversely affect our business.

***Changes to trade policy, including new or increased tariffs and changing import/export regulations, may adversely affect our business, financial condition and results of operations.***

Changes in U.S. or international laws and policies governing foreign trade could materially and adversely affect our business. The U.S. has instituted certain changes, and has proposed additional changes, in trade policies that include the negotiation or termination of trade agreements, the imposition of higher tariffs on imports into the U.S., and other government regulations affecting trade between the U.S. and other countries where we conduct our business. The new tariffs and other changes in U.S. trade policy have triggered retaliatory actions by affected countries, and foreign governments have instituted or are considering imposing trade sanctions on U.S. goods.

The imposition of tariffs and other trade restrictions, as well as the escalation of trade disputes and any downturns in the global economy resulting therefrom, could materially and adversely affect our business, financial condition and results of operations. The extent and duration of the tariffs and other trade restrictions and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our products in affected markets. Further, actions we take to adapt to new tariffs or other trade restrictions may cause us to modify our operations, which could be time-consuming and expensive, impact pricing of our products, which could impact our sales and profitability, or cause us to forgo business opportunities.

**Risks related to our indebtedness**

***Our indebtedness could adversely affect our financial condition and prevent us from fulfilling our debt or contractual obligations.***

We now have and expect to continue to have a significant amount of debt. Our indebtedness could have important consequences to us including: (i) making it more difficult for us to satisfy our debt or

------

contractual obligations; (ii) exposing us to the risk of increased interest rates as certain of our borrowings, including borrowings under our senior secured credit facilities, are at variable rates of interest; (iii) restricting us from making strategic acquisitions or causing us to make non-strategic divestitures; (iv) requiring us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, which would reduce the funds available for working capital, capital expenditures, investments, acquisitions and other general corporate purposes; (v) limiting our flexibility in planning for, or reacting to, changes in our business, future business opportunities and the industry in which we operate; (vi) placing us at a competitive disadvantage compared to any of our less leveraged competitors; (vii) increasing our vulnerability to a downturn in our business and both general and industry-specific adverse economic conditions; and (viii) limiting our ability to obtain additional financing.

Our credit facilities and indentures contain financial and other restrictive covenants that could limit our ability to engage in activities that may be in our long-term best interests. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all of our debt, which could adversely affect our business, earnings and financial condition.

***Despite our current level of indebtedness, we and our subsidiaries may still be able to incur substantially more debt.***

We and our subsidiaries may be able to incur significant additional indebtedness in the future. Although our credit agreement and indentures contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the additional indebtedness incurred in compliance with these restrictions could be substantial. If new debt is added to our current debt levels, the related risks that we now face could intensify. Additionally, we may not be able to obtain additional financing or refinancing on terms acceptable to us, or at all, which could adversely impact our ability to service our outstanding indebtedness or to repay our outstanding indebtedness as it becomes due and could adversely affect our business, earnings and financial condition. Further indebtedness also may increase the risk of a future downgrade in our credit ratings, which could increase future debt costs, limit the future availability of debt financing and adversely affect our business.

**Risks related to ownership of our stock**

***Because we have no current plans to pay cash dividends on our common stock, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.***

We have no current plans to pay cash dividends on our common stock. The declaration, amount and payment of any future dividends on our common stock will be at the sole discretion of our Board of Directors. Our Board of Directors may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, including restrictions under our credit agreement and other indebtedness we may incur, and such other factors as our Board of Directors may deem relevant. As a result, you may not receive any return on an investment in our common stock unless you sell our common stock for a price greater than your purchase price.

***If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results.***

Effective internal controls are necessary for us to provide reliable and accurate financial statements and to effectively prevent fraud. We devote significant resources and time to comply with the internal control

------

over financial reporting requirements of the Sarbanes Oxley Act of 2002 and continue to enhance our controls. However, we cannot be certain that we will be able to prevent future significant deficiencies or material weaknesses. Inadequate internal controls could cause investors to lose confidence in our reported financial information, which could have a negative effect on investor confidence in our financial statements, the trading price of our stock and our access to capital.

***Our amended and restated certificate of incorporation provides, subject to limited exceptions, that state and federal courts (as appropriate) located within the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.***

Our amended and restated certificate of incorporation provides that unless we consent to the selection of an alternative forum, the state or federal courts (as appropriate) located within the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (i) derivative action or proceeding brought on behalf of our company, (ii) action asserting a claim of breach of a fiduciary duty owed by any director, officer, or other employee or stockholder of our company to us or our stockholders, creditors or other constituents, (iii) action against us or any of our directors or officers involving a claim or defense arising pursuant to any provision of the Delaware General Corporation Law or our amended and restated certificate of incorporation or our amended and restated bylaws, (iv) action against us or any director or officer of the Company involving a claim or defense implicating the internal affairs doctrine, or (v) action against us or any of our directors or officers involving a claim or defense arising pursuant to the Exchange Act or the Securities Act. It is possible that these exclusive forum provisions may be challenged in court and may be deemed unenforceable in whole or in part. Our exclusive forum provision shall not relieve the company of its duties to comply with the federal securities laws and the rules and regulations thereunder, and our stockholders will not be deemed to have waived our compliance with these laws, rules and regulations.

Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation. This choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.

***Our business could be impacted as a result of actions by activist shareholders or others.***

We have in the past and may in the future be the focus of shareholder activism, which has become increasingly prevalent. Shareholder activism, particularly with respect to matters that our Board, in exercising its fiduciary duties, disagrees with, or has determined not to pursue, may adversely affect our business because responding to activist shareholders can be costly and time-consuming, disruptive to operations and divert the attention of our Board and management. Our ability to execute our strategic plan could also be impaired as a result. Responding to an activist campaign could cause us to incur substantial fees and expenses and could also lead to litigation, which could be a further distraction to our Board and management and require us to incur significant additional costs.

------

Perceived uncertainties as to our future direction, strategy or leadership created as a consequence of activist shareholders may result in the loss of potential business opportunities, harm our ability to attract new or retain existing investors, lenders, customers, directors, employees, or other partners, and negatively affect or create volatility in our stock price.

**Item 1B.&nbsp;&nbsp;&nbsp;&nbsp;Unresolved staff comments**

None.

**Item 1C.&nbsp;&nbsp;&nbsp;&nbsp;Cybersecurity**

**Risk Management and Strategy**

We rely on sophisticated information systems to obtain, rapidly process, analyze, and manage data in order to effectively operate our business. We are committed to protecting our business information, intellectual property, customer, supplier and employee data and information systems from cybersecurity risks and maintain an active cybersecurity risk management and strategy program, which is integrated in our enterprise risk management program.

We maintain enterprise-wide information security policies, standards, and procedures that govern acceptable use of systems and data, risk assessment and management, identity and access management, data security, security operations, incident response, and threat and vulnerability management. We perform formal risk assessments annually, aligned with the National Institute of Standards and Technology (NIST) Special Publication 800-171 and the NIST Cybersecurity Framework, to help ensure the confidentiality, integrity, and availability of our information systems and data. In August 2025, Avantor achieved ISO/IEC 27001 certification, reflecting the maturity of our Information Security Management System (ISMS) and providing independent validation of our security governance, risk management, and control environment. This certification complements our alignment with NIST-based frameworks and supports our continued focus on risk-informed control implementation, continuous improvement, and operational resilience. Our team of information security professionals monitors systems for cybersecurity threats, intrusions, and vulnerabilities; responds to incidents; develops and implements mitigation strategies; and facilitates cybersecurity training across the organization. We also engage consultants and other third-party advisors to conduct independent assessments of our cybersecurity readiness and control effectiveness. In collaboration with external cybersecurity firms, we seek to gain insights into emerging threats and vulnerabilities, industry trends, and leading practices to inform our cybersecurity response, risk remediation and resilience capabilities, including by working with an external retained incident response team, receiving third-party threat intelligence, participating in incident tabletops, and performing assessments and controls testing on our enterprise environment.

Our program includes procedures to oversee and identify cybersecurity risks and threats of our third-party service providers, which include third-party evaluations performed by our team of information security professionals, review of independent assessment documentation, and continuous monitoring of third-party independent posture scoring. We also include security and data protection provisions in our contractual arrangements with third-party service providers where applicable. Additionally, we have purchased a cybersecurity risk insurance policy that would reduce the costs associated with a covered cybersecurity incident if it occurred.

Although no cybersecurity incident during the year ended December 31, 2025 resulted in an interruption of our operations, known losses of critical data, or otherwise had a material impact on Avantor's strategy, financial condition or results of operations, the scope and impact of any future incident cannot be predicted. See "Item 1A. Risk Factors" for more information on how material cybersecurity attacks may impact our business.

------

**Governance**

Management plays a critical role in assessing and managing material risks from cybersecurity threats. Our Vice President of Information Security & Risk Management and Chief Information Security Officer (CISO), in coordination with our Chief Information Officer, leads a team of information security professionals and manages our cybersecurity risk management program and activities. This involves monitoring our information systems for cybersecurity threats, reviewing cybersecurity incidents, analyzing emerging threats, and the development and implementation of risk mitigation strategies. Our CISO has over 25 years of experience working in the information technology and services industry and is a subject matter expert in a variety of areas including information security, and IT risk.

Our CISO reports to our executive leadership team composed of our Chief Executive Officer, Chief Financial Officer, and Chief Information Officer on cybersecurity matters, providing the leadership team with updates on enterprise risks, cybersecurity incidents, the status of ongoing initiatives, key metrics, and additional cybersecurity topics. Our information technology leaders also meet regularly to discuss the progress of ongoing program initiatives, cybersecurity priorities, identified risks and metrics. We have also developed a cross functional disclosure working group to assess elevated cybersecurity incidents and, as appropriate, report on such events to Avantor's standing Disclosure Committee to conclude on the materiality of the incident and any need for regulatory reporting.

The Board of Directors exercises direct oversight of strategic risks to the Company. The Board has delegated the responsibility for cybersecurity oversight to the Audit and Finance Committee. The Audit and Finance Committee's responsibilities include reviewing and discussing with management the strategies, process and controls pertaining to the management of Avantor's information technology operations, including cybersecurity risks and information security. The CISO and Chief Information Officer report to the Audit and Finance Committee annually and more frequently, as needed, on cybersecurity matters, including the cybersecurity threat landscape, key metrics demonstrating the overall management of our cybersecurity risk and risk management program, related key initiatives, enterprise program framework alignment, annual risk mitigation strategy, and review of cybersecurity incidents. Our Board is committed to maintaining a well-informed and cybersecurity-aware posture, regularly engaging through regular and requested updates on our strategy and evolving threat landscape.

**Item 2.&nbsp;&nbsp;&nbsp;&nbsp;Properties**

As of December 31, 2025, the Company had facilities in over 30 countries, including approximately 200 significant administrative, sales, research and development, manufacturing and distribution facilities. Approximately 65 of these facilities are located in the United States across 20 states. Approximately 135 of these facilities are located outside the United States, primarily in Europe and to a lesser extent in AMEA. Refer to the Consolidated Financial Statements included in this Annual Report for additional information with respect to the Company's lease commitments.

**PART II**

**Item 5.&nbsp;&nbsp;&nbsp;&nbsp;Market for registrant's common equity, related stockholder matters and issuer purchases of equity securities**

**Principal markets for common stock**

Our common stock is listed on the NYSE under the symbol "AVTR."

**Holders of common stock**

On February 5, 2026, we had 7 holders of record of our common stock. This does not include holdings in street or nominee names.

**Dividends**

We currently do not expect to pay any dividends on our common stock. Our ability to pay dividends is limited by the terms of our indebtedness. Certain of the debt agreements entered into by our wholly-owned subsidiaries restrict their ability to pay dividends or make other distributions to Avantor, Inc., which in turn limits our ability to fund future dividends or make other distributions to our common stockholders.

Additional information regarding these restrictions is included in the Liquidity and Capital Resources section of Management's Discussion and Analysis and in note 14 to our consolidated financial statements beginning on page F-1 of this report.

**Stock performance graph**

The following performance graph compares the cumulative five-year return to shareholders on our common stock relative to the cumulative total returns of the S&P 500 Index and the S&P 500 Health Care Index for the five-year period ended December 31, 2025. The comparisons assume the investment of $100 on December 31, 2020 in our common stock and in each index. The S&P 500 Index is a broad equity market index of companies having market capitalization similar to ours. The S&P 500 Health Care Index is an industry-specific equity market index that we believe closely aligns to us based on the following: (i) the index follows companies of a similar size to us in terms of net sales and market capitalization; (ii) the index includes health care distributors, the segment of the Global Industry Classification Standard that we believe most closely aligns to us; and (iii) the index includes companies in the biopharma and healthcare industries, two of our primary customer groups that together comprise over half of our net sales.

The information in this section is not "soliciting material," is not deemed "filed" with the SEC and is not to be incorporated by reference in any of our filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date of this report, except to the extent that we specifically incorporate such information by reference.

**Item 6.&nbsp;&nbsp;&nbsp;&nbsp;[Reserved]**

**Item 7.&nbsp;&nbsp;&nbsp;&nbsp;Management's discussion and analysis of financial condition and results of operations**

*This discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results may differ materially from those contained in or implied by any forward-looking statements. See "Cautionary factors regarding forward-looking statements."*

**Overview**

For the fiscal year ended December 31, 2025, we recorded net sales of $6,552.2 million, net loss of $530.2 million, Adjusted EBITDA of $1,069.4 million and Adjusted Operating Income of $957.8 million. Net sales declined 3.4% which included 2.8% organic net sales decrease compared to the same period in 2024. See "Reconciliations of non-GAAP measures" for reconciliations of net (loss) income to Adjusted EBITDA and Adjusted Operating Income, and net (loss) income margin to Adjusted EBITDA margin and Adjusted Operating Income margin. See "Results of operations" for a reconciliation and explanation of changes of net sales growth (decline) to organic net sales growth (decline).

**Segment change**

Effective January 1, 2024, we changed our operating model and reporting segment structure from three reportable segments to two reportable segments, Laboratory Solutions and Bioscience Production. This structure aligns with how our Chief Executive Officer, who is our CODM, measures segment operating performance and allocates resources across our operating segments. This reportable segment change has no impact on our consolidated operating results.

In connection with the operating model and reporting structure change, our CODM changed the measure used to evaluate segment profitability from Adjusted EBITDA to Adjusted Operating Income. All disclosures relating to segment profitability, including those for comparative periods, have been revised as a result of this change.

**Trends affecting our business and results of operations**

The following trends have affected our recent operating results, and they may also continue to affect our performance and financial condition in future periods.

***Our results are impacted by a divestiture to further refine our business model***

We completed the sale of our Clinical Services business, a component of the Company's Laboratory Solutions reportable segment, on October 17, 2024. The Clinical Services business was not classified as a discontinued operation as it did not represent a strategic shift that will have a major effect on the Company's operations and financial results.

***We have been impacted by inflationary pressures***

We have experienced inflationary pressures across all of our cost categories. While we have implemented pricing and productivity measures to combat these pressures, they may continue to adversely impact our results.

------

***We continue to invest in a differentiated innovation model***

We are engaging with our customers early in their product development cycles to advance their programs from research and discovery through development and commercialization. These projects include enhancing product purity and performance characteristics, improving product packaging and streamlining workflows. We are also developing new products in emerging areas of science such as cell and gene therapy.

***We continue to advance our cost transformation initiative to reduce our expenses***

We are advancing a global cost transformation initiative to further enhance productivity through increased organizational efficiency, footprint optimization, reduced cost-to-serve and procurement savings that are expected to generate approximately $300 million in run rate gross cost savings by the end of 2026.

We have expanded this initiative and now expect to generate approximately $400 million in run rate gross savings by the end of 2027.

***We refinanced our debt and increased our liquidity***

In the fourth quarter of 2025, we issued €400.0 million and €550.0 million of senior secured term loans, maturing in October 2030 and October 2032, respectively. These loans bear interest at EURIBOR plus 150 basis points and EURIBOR plus 250 basis points, respectively. The proceeds from these issuances, along with cash on hand, were used to repay our outstanding U.S. dollar term loans B-6, Euro term loans B-4, Euro term loans B-5, the remaining 2.625% secured notes, and the receivables facility.

In connection with the refinancing, we amended our revolving credit facility to obtain an additional $425.0 million in available funding, increasing the total availability under the facility to $1,400.0 million.

***Changes in foreign currency exchange rates are impacting our financial condition and results of operations***

Our consolidated results of operations are comprised of many different functional currencies that translate into our U.S. dollar reporting currency. The movement of the U.S. dollar against those functional currencies, particularly the Euro, has caused significant variability in our results and may continue to do so in the future. See Part I, Item 7A, "Quantitative and qualitative disclosures about market risk."

***Our results may be impacted by changes in trade policy***

The imposition of tariffs and other trade restrictions by the U.S., as well as reciprocal trade restrictions imposed by other countries, could adversely affect global economies, financial markets and the overall environment in which we do business.

***Goodwill impairment related to our Distribution reporting unit***

In the third quarter of 2025, we recorded a goodwill impairment charge of $785.0 million related to our Distribution reporting unit, formerly referred to as our Buy Sell reporting unit. This impairment was primarily driven by sustained decreases in our publicly quoted share price and market capitalization, as well as changes in operating results. While the impairment is a non-cash charge, it reflects underlying business conditions that may continue to affect our future results. We are actively implementing initiatives and evaluating strategic actions to mitigate these pressures.

------

**Key indicators of performance and financial condition**

To evaluate our performance, we monitor a number of key indicators. As appropriate, we supplement our results of operations determined in accordance with GAAP with certain non-GAAP financial measurements that we believe are useful to investors, creditors and others in assessing our performance. These measures should not be considered in isolation or as a substitute for reported GAAP results because they may include or exclude certain items as compared to similar GAAP-based measures, and such measures may not be comparable to similarly titled measures reported by other companies. Rather, these measures should be considered as an additional way of viewing aspects of our operations that provide a more complete understanding of our business.

The key indicators that we monitor are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Net sales, gross margin, operating income, operating income margin, net income or loss and net income or loss margin***. These measures are discussed in the section entitled "Results of operations";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Organic net sales growth (decline)***, which is a non-GAAP measure discussed in the section entitled "Results of operations." Organic net sales growth (decline) eliminates from our reported net sales change the impacts of revenues from acquisitions and divestitures that occurred in the last year (as applicable) and changes in foreign currency exchange rates. We believe that this measurement is useful to investors as a way to measure and evaluate our underlying commercial operating performance consistently across our segments and the periods presented. This measurement is used by our management for the same reason. Reconciliations to the change in reported net sales, the most directly comparable GAAP financial measure, are included in the section entitled "Results of operations";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Adjusted EBITDA and Adjusted EBITDA margin***, which are non-GAAP measures discussed in the section entitled "Results of operations." Adjusted EBITDA is our net income or loss adjusted for the following items: (i) interest expense, (ii) income tax expense, (iii) amortization of acquired intangible assets, (iv) depreciation expense, (v) losses on extinguishment of debt, (vi) charges associated with the impairment of certain assets, (vii) gain on sale of business, and (viii) certain other adjustments. Adjusted EBITDA margin is Adjusted EBITDA divided by net sales as determined under GAAP. We believe that these measurements are useful to investors as ways to analyze the underlying trends in our business consistently across the periods presented. These measurements are used by our management for the same reason. A reconciliation of net income or loss and net income or loss margin, the most directly comparable GAAP financial measures, to Adjusted EBITDA and Adjusted EBITDA margin, respectively, are included in the section entitled "Reconciliations of non-GAAP measures";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Adjusted Operating Income and Adjusted Operating Income margin***, which are non-GAAP measures discussed in the section entitled "Results of operations." Adjusted Operating Income is our net income or loss adjusted for the following items: (i) interest expense, (ii) income tax expense, (iii) amortization of acquired intangible assets, (iv) losses on extinguishment of debt, (v) charges associated with the impairment of certain assets, (vi) gain on sale of business, and (vii) certain other adjustments. This measurement is our segment reporting profitability measure under GAAP. Adjusted Operating Income margin is Adjusted Operating Income divided by net sales as determined under GAAP. We believe that these measurements are useful to investors as ways to analyze the underlying trends in our business consistently across the periods presented. These

------

measurements are used by our management for the same reason. A reconciliation of net income or loss and net income or loss margin, the most directly comparable GAAP financial measures, to Adjusted Operating Income and Adjusted Operating Income margin, respectively, are included in the section entitled "Reconciliations of non-GAAP measures";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Cash flows from operating activities***, which we discuss in the section entitled "Liquidity and capital resources—Historical cash flows";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Free cash flow***, which is a non-GAAP measure, is equal to our cash flows from operating activities, less capital expenditures, plus direct transaction costs and income taxes paid related to acquisitions and divestitures (as applicable) in the period. We believe that this measurement is useful to investors as it provides a view on the Company's ability to generate cash for use in financing or investing activities. This measurement is used by management for the same reason. A reconciliation of cash flows from operating activities, the most directly comparable GAAP financial measure, to free cash flow, is included in the section entitled "Liquidity and capital resources—Historical cash flows."

**Results of operations**

We present results of operations in the same way that we manage our business, evaluate our performance and allocate our resources. We also provide discussion of net sales and Adjusted Operating Income by segment: Laboratory Solutions and Bioscience Production. Corporate costs are managed on a standalone basis, certain of which are allocated to our reportable segments.

For the year ended December 31, 2025, net sales declined primarily due to the divestiture of our Clinical Services business within our Advanced Lab Services business and reduced customer demand in the Total Science Solutions business, both of which impacted the Laboratory Solutions segment. Gross margin and gross profit decreased, reflecting lower sales volume, inflationary pressures, the divestiture of our Clinical Services business and higher freight costs. Operating income declined largely due to a non-cash goodwill impairment charge recorded in the Distribution reporting unit in the current year and the absence of the

gain on sale of the Clinical Services business recognized in the prior year. The reduction in gross profit, partially offset by lower SG&A expenses, resulted in contraction of Adjusted EBITDA and Adjusted Operating Income margins.

---

Net sales decreased $231.4 million or 3.4%, which included $104.7 million or 1.6% of favorable foreign currency translation impact and $147.9 million or 2.2% of impact related to our Clinical Services divestiture. Organic net sales decreased by $188.2 million or 2.8% which is discussed below.

In the Laboratory Solutions segment, net sales decreased $210.4 million or 4.6% which included $86.0 million or 1.8% of favorable foreign currency translation impact and $147.9 million or 3.2% of impact related to our Clinical Services divestiture. Organic net sales decreased by $148.5 million or 3.2%. The sales decline was primarily driven by decreased demand for consumables and equipment and instrumentation from our Total Science Solutions business due to the uncertainty around funding and increased competitive intensity.

In the Bioscience Production segment, net sales decreased $21.0 million or 1.0%, which included $18.7 million or 0.8% of favorable foreign currency translation impact. Organic net sales decreased $39.7 million or 1.8%. The sales decrease was primarily driven by lower demand for third party clean room consumables due to reduced usage and decreased volume in our proprietary clinical and industrial chemicals offerings. These decreases were partially offset by increased volume of our formulated offerings to customers in the semiconductor industry.

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating (loss) income | $(246.2) | $1084.8 | $(1331.0) |

---

Operating (loss) income decreased primarily due to a non-cash impairment charge recorded in our Distribution reporting unit, the absence of the gain on sale of our Clinical Services business recognized in the prior year, and lower gross profit, as previously discussed. These impacts were partially offset by a reduction in SG&A expenses. The decrease in SG&A expenses resulted from lower restructuring and severance charges, reduced annual incentive compensation expense, savings from our cost transformation initiative and the divestiture of our Clinical Services business, partially offset by inflationary pressures.

---

Net (loss) income decreased primarily due to lower operating income, as previously discussed, and pension termination charges, partially offset by lower interest expense resulting from debt repayments made over the last twelve months and lower income tax expense driven by reduced income before income taxes.

------

Adjusted EBITDA decreased $129.4 million or 10.8%, which included a favorable foreign currency translation impact of $16.4 million or 1.3%. The remaining decline of $145.8 million or 12.1% was primarily driven by the divestiture of our Clinical Services business and lower gross profit, as previously discussed, partially offset by savings from our cost transformation initiative and lower annual incentive compensation expense.

Adjusted Operating Income decreased $132.0 million or 12.1%, which included a favorable foreign currency translation impact of $13.5 million or 1.2%. The remaining decline of $145.5 million or 13.3% is discussed below.

In the Laboratory Solutions segment, Adjusted Operating Income declined $87.6 million or 14.6%, or 16.2% when adjusted for favorable foreign currency translation impact. The decrease was primarily driven by the divestiture of our Clinical Services business, lower sales volume and inflationary pressures, partially offset by savings from our cost transformation initiative and lower annual incentive compensation expense.

In the Bioscience Production segment, Adjusted Operating Income declined $40.4 million or 7.2% or 8.0% when adjusted for favorable foreign currency translation impact. The decrease was primarily driven by lower sales volume, unfavorable manufacturing variances and higher freight costs, partially offset by commercial excellence, savings from our cost transformation initiative and lower annual incentive compensation expense.

In Corporate, Adjusted Operating Income decreased $4.0 million due to various immaterial factors.

**Liquidity and capital resources**

We fund short-term cash requirements primarily from operating cash flows and credit facilities. The majority of our long-term financing is from indebtedness.

Our most significant contractual obligations are scheduled principal and interest payments for indebtedness. We also have obligations to make payments under operating leases, to purchase certain products and services and to fund defined benefit plan obligations, primarily outside of the United States.

------

In addition to contractual obligations, we use cash to fund capital expenditures and taxes. Changes in working capital may be a source or a use of cash depending on our operations during the period.

We expect to fund our short-term and long-term capital needs with cash generated by operations and availability under our credit facilities. Although we believe that these sources will provide sufficient liquidity for us to meet our long-term capital needs, our ability to fund these needs will depend to a significant extent on our future financial performance, which will be subject in part to general economic, competitive, financial, regulatory and other factors that are beyond our control.

We believe that cash generated by operations, together with available liquidity under our credit facilities, will be adequate to meet our current and expected needs for cash prior to the maturity of our debt, although no assurance can be given in this regard.

In October 2025, our Board of Directors authorized the repurchase of up to $500.0 million of our common stock. Repurchases may be funded through available cash, borrowings under existing credit facilities, or other financing arrangements. The program may be modified, suspended, or terminated at any time.

In November 2025, we repurchased $75.0 million of our common stock. As of December 31, 2025, $425.0 million remained available for repurchase under the program. Refer to Note 15 to the Consolidated Financial Statements included in this Annual Report for additional discussion of our common stock repurchase program.

***Liquidity***

The following table presents our primary sources of liquidity:

---

|:---|:---|
| *(in millions)* | |
|  | **December 31, 2025** |
| Unused availability under our revolving credit facility: |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Capacity | $1400.0 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Undrawn letters of credit outstanding | (19.5) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unused availability | $1380.5 |
| Cash and cash equivalents | 365.4 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total liquidity | $1745.9 |

---

At December 31, 2025, $243.1 million or 67% of our cash and cash equivalents was held by our non-U.S. subsidiaries and may be subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply. We ordinarily generate significant cash flows in the U.S. and deploy U.S. cash flows promptly toward debt principal repayment. Our U.S. operations also benefit from substantial liquidity available under our credit facilities, which support our day-to-day operating cash needs.

***Historical cash flows***

The following table presents a summary of cash provided by (used in) various activities:

---

|:---|:---|:---|:---|
| *(in millions)* | **Year ended December 31,** | **Year ended December 31,** | **Change** |
| *(in millions)* | **2025** | **2024** | **Change** |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net (loss) income | $(530.2) | $711.5 | $(1241.7) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Non-cash items<sup>1</sup> | 1354.2 | 81.9 | 1272.3 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Working capital changes<sup>2</sup> | (53.0) | 89.9 | (142.9) |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total | $(130.5) | $438.9 | $(569.4) |
| Financing activities | (409.4) | (1281.2) | 871.8 |

---

1. Consists of non-cash charges including depreciation and amortization, impairment charges, stock-based compensation expense, deferred income tax expense, non-cash restructuring charges, pension termination charges, gain on sale of business and others.

2. Includes changes to our accounts receivable, inventory, contract assets and accounts payable.

Cash flows from operating activities provided $217.0 million less cash in 2025. The change was primarily due to higher net working capital requirements, increased customer rebate payments and higher incentive compensation payments made in 2025 related to fiscal year 2024.

Investing activities provided $569.4 million less cash in 2025, primarily due to the absence of proceeds from the sale of our Clinical Services business, which were received in the prior year.

Financing activities provided $871.8 million more cash in 2025, primarily due to lower net debt repayments during the year, partially offset by payments for the repurchase of common stock in 2025 and a decrease in proceeds from stock option exercises compared to the prior year.

***Free cash flow***

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Free cash flow | $496.4 | $768.3 | $(271.9) |

---

Free cash flow was $271.9 million lower in 2025 driven by changes in cash flows from operating activities noted above, partially offset by a decrease in capital expenditures.

A discussion and analysis of historical cash flows covering the year ended December 31, 2023 is included in Item 7 of the 2024 Form 10-K.

***Indebtedness***

A significant portion of our long-term financing is from indebtedness. The purpose of this section is to disclose how certain features of our indebtedness influence our liquidity and capital resources. Additional detail about the terms of our indebtedness may be found in note 14 to our consolidated financial statements beginning on page F-1 of this report.

*Our credit facilities provide us access to up to $1,400.0 million of borrowing capacity.*

We have entered into a revolving credit facility that provide us access to cash to fund short-term business needs. See the section entitled "Liquidity" for additional information.

*Our indebtedness restricts us from paying dividends to common stockholders.*

Certain of the debt agreements entered into by our wholly-owned subsidiary, Avantor Funding, Inc., prevent it from paying dividends or making other payments to Avantor, Inc., subject to limited exceptions. At December 31, 2025 and 2024, substantially all of Avantor, Inc.'s net assets were subject to those restrictions.

*Our senior secured credit facilities require or may require us to make certain principal repayments prior to maturity*

We are required to make quarterly payments on our senior secured credit facilities, with the balance due on the maturity date. We have generated sufficient cash flows to make all required historical payments, and we expect that our cash flows will continue to be sufficient to make future payments.

To the extent our net leverage ratios, as defined in our credit agreement, reach certain levels, we are required to make additional prepayments if: (i) we generate excess cash flows, as defined in our credit agreement, at specified percentages that decline if certain net leverage ratios are achieved; or (ii) we receive cash proceeds from certain types of asset sales or debt issuances. We are required to make a prepayment of 50% of our excess cash flows if our first lien net leverage ratio, as defined in our credit agreement, exceeds 4.50:1.00, a prepayment of 25% of our excess cash flows if our first lien net leverage ratio is less than or equal to 4.50:1.00 but greater than 3.75:1.00, and no prepayment if our first lien net

------

leverage ratio is less than or equal to 3.75:1.00. As our first lien net leverage ratio was below 3.75:1.00 at December 31, 2025, no additional prepayments were required and no such prepayments have become due since the inception of the credit facilities.

*We are subject to certain financial covenants that, if not met, could put us in default of our debt agreements*

The revolving credit facility and our senior secured credit facilities contain certain customary covenants, including financial covenants. We may not have total borrowings and total interest expense in excess of a pro forma net leverage ratio and pro forma consolidated interest coverage ratio, as defined, respectively. At December 31, 2025, our net leverage and consolidated interest coverage ratio has been within the covenant requirement.

***Contractual obligations***

The following table presents our contractual obligations at December 31, 2025:

---

| | | | |
|:---|:---|:---|:---|
| *(in millions)* | **Payments due by period** | **Payments due by period** | **Payments due by period** |
| *(in millions)* | **Total** | **Short-Term** | **Long-Term** |
| Debt: |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Principal<sup>(1)(2)</sup> | $3967.9 | $30.8 | $3937.1 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest<sup>(1)</sup> | 602.9 | 166.7 | 436.2 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating leases | 245.7 | 43.0 | 202.7 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Purchase obligations<sup>(3)</sup> | 223.4 | 113.0 | 110.4 |
| Other liabilities: |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Underfunded defined benefit plans<sup>(4)</sup> | 94.2 | 6.7 | 87.5 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Other | 4.7 | 1.2 | 3.5 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total | $5138.8 | $361.4 | $4777.4 |

---

(1)Includes finance lease liabilities. To calculate payments for principal and interest, we assumed that variable interest rates, foreign currency exchange rates and outstanding borrowings under credit facilities were unchanged from December 31, 2025 through maturity. For the variable interest rates and principal amounts used, see note 14 to our consolidated financial statements beginning on page F-1 of this report.

(2)Our senior secured credit facilities would require us to accelerate our principal repayments should we generate excess cash flows, as defined, in future periods.

(3)Purchase obligations for certain products and services are made in the normal course of business to meet operating needs.

(4)Represents our obligation to fund defined benefit plans with obligations in excess of plan assets. The total obligation is equal to the aggregate excess of the discounted benefit obligation over the fair value of plan assets for all underfunded plans. The payments due in less than one year are estimated using actuarial methods. The payments due for all other years are estimated by distributing the remaining funding status to future periods in the same way as benefit payments are expected to be made by the plans following actuarial methods.

**Critical accounting policies and estimates**

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported throughout the financial statements. Those estimates and

------

assumptions are based on our best estimates and judgment. We evaluate our estimates and assumptions on an ongoing basis using historical experience and known facts and circumstances. We adjust our estimates and assumptions when we believe the facts and circumstances warrant an adjustment. As future events and their effects cannot be determined with precision, actual results could differ significantly from those estimates.

We consider the policies and estimates discussed below to be critical to an understanding of our financial statements because their application places the most significant demands on our judgment. Specific risks for these critical accounting policies are described in the following sections. For all of these policies, we caution that future events rarely develop exactly as forecasted, and such estimates naturally require adjustment.

Our discussion of critical accounting policies and estimates is intended to supplement, not duplicate, our summary of significant accounting policies so that readers will have greater insight into the uncertainties involved in these areas. For a summary of all of our significant accounting policies, see note 2 to our consolidated financial statements beginning on page F-1 of this report.

***Testing goodwill and other intangible assets for impairment***

We carry significant amounts of goodwill and other intangible assets on our consolidated balance sheet. At December 31, 2025, the combined carrying value of goodwill and other intangible assets, net of accumulated amortization and impairment charges, was $8,180.7 million or 69% of our total assets.

*Required annual assessment*

On October 1 of each year, we perform annual impairment testing of our goodwill and indefinite-lived intangible assets, or more frequently if an event or change in circumstance occurs that would require reassessment of the recoverability of those assets. The impairment analysis for goodwill and indefinite-lived intangible assets consists of an optional qualitative test potentially followed by a quantitative analysis. These measurements rely upon significant judgment from management described as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The qualitative analysis for goodwill and indefinite-lived intangible assets requires us to identify potential factors that may result in an impairment and estimate whether they would warrant performance of a quantitative test;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The quantitative impairment test requires us to estimate the fair value of our reporting units and indefinite-lived intangible assets. We estimate the fair value of each reporting unit using a weighted average of two valuation methods based on a discounted cash flows method and a guideline public company method. These valuation methods require management to make various assumptions, including, but not limited to, future profitability, cash flows, including revenues, gross margin, SG&A expenses, capital expenditures, and investments in debt free net working capital, current market assumptions for the discount rates, weighting of valuation methods and the selection of comparable publicly traded companies. Variations in any of these assumptions could result in materially different calculations of fair value.

Our estimates are based on historical trends, management's knowledge and experience and overall economic factors, including projections of future earnings potential. Developing future cash flows in applying the income approach requires us to evaluate our intermediate to longer-term strategies, including, but not limited to, estimates about net sales growth, operating margins, capital requirements, inflation and working capital management. The development of appropriate rates to discount the

------

estimated future cash flows requires the selection of risk premiums, which can materially impact the present value of future cash flows. Selection of an appropriate peer group under the market approach involves judgment, and an alternative selection of guideline companies could yield materially different market multiples. Weighing the different value indications involves judgment about their relative usefulness and comparability to the reporting unit.

As a result of sustained decreases in our publicly quoted share price and market capitalization as well as changes in the operating results of our Distribution reporting unit, we conducted an interim test of our goodwill as of September 30, 2025.

Based on the results of the impairment test, the carrying amount of our Distribution reporting unit exceeded its fair value, resulting in a non-deductible, non-cash goodwill impairment charge of $785.0 million, which was recorded in the consolidated statement of operations for the three months ended September 30, 2025. We did not identify impairment of any other long-lived assets in this reporting unit. The remaining reporting units tested were not impaired, as their estimated fair values exceeded their respective carrying amounts as of the interim testing date.

Following the impairment charge, the carrying value of the Distribution reporting unit is equal to its estimated fair value. Recognition of additional impairment charges may be required in future periods if market conditions, projected results, or other valuation assumptions deteriorate further.

Since October 1, 2025 is our designated annual impairment testing date, management performed the required procedures to reassess impairment as of that date, including a review of key assumptions, market indicators, and other relevant factors. No conditions were identified that differed materially from those considered in the September 30, 2025 interim analysis. Accordingly, the conclusions reached in that interim test remained appropriate, and no additional impairment was recorded as of October 1, 2025.

***Estimating valuation allowances on deferred tax assets***

We are required to estimate the degree to which tax assets and loss carryforwards will result in a future income tax benefit, based on our expectations of future profitability by tax jurisdiction. We provide a valuation allowance for deferred tax assets that we believe will more likely than not go unutilized. If it becomes more likely than not that a deferred tax asset will be realized, we reverse the related valuation allowance and recognize an income tax benefit for the amount of the reversal. At December 31, 2025, our valuation allowance on deferred tax assets was $190.1 million, $132.1 million of which relates to foreign net operating loss carry forwards that are not expected to be realized.

We must make assumptions and judgments to estimate the amount of valuation allowance to be recorded against our deferred tax assets, which take into account current tax laws and estimates of the amount of future taxable income, if any. Changes to any of the assumptions or judgments could cause our actual income tax obligations to differ from our estimates.

***Accounting for uncertain tax positions***

In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess income tax positions for all years subject to examination based upon our evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded an amount having greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority assumed to have full knowledge of all relevant information. For those income tax positions where it is not more likely than not

------

that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Our reserve for uncertain tax positions was $106.9 million at December 31, 2025, exclusive of penalties and interest. Where applicable, associated interest expense has also been recognized as a component of interest expense.

We operate in numerous countries under many legal forms and, as a result, we are subject to the jurisdiction of numerous domestic and non-U.S. tax authorities, as well as to tax agreements and treaties among these governments. Our tax positions may be scrutinized by local tax authorities upon examination. Determination of taxable income in any jurisdiction requires the interpretation of the related tax laws and regulations, including transfer pricing guidelines, and the use of estimates and assumptions regarding significant future events, such as the amount, timing and character of deductions and the sources and character of income and tax credits. Changes in tax laws, regulations, agreements and treaties, currency exchange restrictions or our level of operations or profitability in each taxing jurisdiction could have an impact upon the amount of current and deferred tax balances and hence our net income.

We file tax returns in each tax jurisdiction that requires us to do so. Should tax return positions not be sustained upon audit, we could be required to record an income tax provision. Should previously unrecognized tax benefits ultimately be sustained, we could be required to record an income tax benefit.

***Calculating expense for long-term compensation arrangements***

Our employees receive various long-term compensation awards, including stock options, RSUs, performance stock units and cash-based awards. We calculate expense for some of those awards using fair value estimates based on unobservable inputs. Additionally, some of those awards contain performance or market conditions. We assess the probability of achieving those performance conditions, and in cases where partial or exceptional performance affects the size of the award, we also estimate the projected achievement level. We determine the fair value of awards with market conditions on their grant date using a Monte Carlo model, which incorporates the probability of achieving the market condition in the awards' fair value. We recognize the expense for such awards ratably over their vesting term.

Expense for stock options without performance or market conditions is determined on the grant date and recognized ratably over their vesting term. We estimate the grant date fair value of stock options using the Black-Scholes model. This model requires us to make various assumptions, with the most significant assumption currently being the volatility of our stock price. Through the year ended December 31, 2024, due to limited trading history, we estimated volatility using a peer group approach. Beginning in 2025, after sufficient trading history became available, we adopted a blended volatility methodology that combines Avantor's historical volatility with that of a peer group to provide a more stable and representative input. This approach is consistent with ASC 718 and SEC guidance for companies with evolving trading history. The fair value of our awards would have differed had we selected different peer companies or used a different technique to estimate volatility. Increasing our expected volatility assumption by 5 percentage points for all stock options at the date of grant would have increased our 2025 stock-based compensation expense by $0.9 million.

***Estimating the net realizable value of inventories***

We value our inventories at the lower of cost or net realizable value. We regularly review quantities of inventories on hand and compare these amounts to the expected use of each product or product line, which can require us to make significant judgments. If our judgments prove to be incorrect, we may be

------

required to record a charge to cost of sales to reduce the carrying amount of inventory on hand to net realizable value. As with any significant estimate, we cannot be certain of future events which may cause us to change our judgments.

**Item 7A.&nbsp;&nbsp;&nbsp;&nbsp;Quantitative and qualitative disclosures about market risk**

**Foreign currency exchange risk**

Although we report our results and financial condition in U.S. dollars, a significant portion of our operating and financing activities are denominated in foreign currencies, principally the Euro but also many others.

Certain of our U.S. subsidiaries carry Euro-denominated debt. This does not result in any material risks from an earnings perspective because the exposure from these instruments is substantially hedged by offsetting exposures from intercompany borrowing arrangements and from our derivative and hedging instruments. From a cash flow perspective, we have the risk of paying more or less cash for any optional or mandatory repayments of our Euro-denominated debt that may not be offset with equivalent cash repayments of our intercompany borrowings. For example, an optional debt repayment of €100 million on December 31, 2025 and December 31, 2024, with a 10% weakening of the U.S. dollar would have caused us to pay an additional $11.7 million and $10.3 million, respectively, to extinguish that debt.

Changes to foreign currency exchange rates could favorably or unfavorably affect the translation of our foreign operating results. For example, during times of a strengthening U.S. dollar, our reported international sales and earnings will be reduced because local currencies will translate into fewer U.S. dollars. For the year ended December 31, 2025, a 10% strengthening of the U.S. dollar compared to all other currencies would have decreased net income by $0.5 million and decreased Adjusted Operating Income by $26.2 million. For the year ended December 31, 2024, a 10% strengthening of the U.S. dollar compared to all other currencies would have decreased net income by $16.2 million and decreased Adjusted Operating Income by $30.6 million.

**Interest rate risk**

We carry debt that exposes us to interest rate risk. A portion of our debt consists of variable-rate instruments. We have also issued fixed-rate secured and unsecured notes. None of our other financial instruments are subject to material interest rate risk.

At December 31, 2025, we had borrowings of $1,114.4 million under our senior secured credit facilities. Borrowings under these facilities bear interest at variable rates based on prevailing EURIBOR and SOFR rates in the financial markets. Changes to those market rates affect both the amount of cash we pay for interest and our reported interest expense. At December 31, 2025, a 100 basis point increase to the applicable variable rates of interest would have increased the amount of interest by $11.1 million per annum. At December 31, 2024, a 100 basis point increase to the applicable variable rates of interest would have increased the amount of interest by $5.2 million per annum.

Our senior secured notes and senior unsecured notes bear interest at fixed rates, so their fair value will increase if interest rates fall and decrease if interest rates rise. At December 31, 2025, a 100 basis point decrease in the market rate of interest would have increased their aggregate fair value by $75.9 million. At December 31, 2024, a 100 basis point decrease in the market rate of interest would have increased their aggregate fair value by $99.9 million.

**Management's evaluation of disclosure controls and procedures**

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of December 31, 2025. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2025, our disclosure controls and procedures were effective in providing reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized, reported, accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

**Changes in internal control over financial reporting**

There have been no changes to our internal control over financial reporting during the fiscal quarter ended December 31, 2025 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

**Management's annual report on internal control over financial reporting**

Our management, including our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the company. 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 accounting principles generally accepted in the United States of America. 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. Our management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025 based on criteria established in *Internal Control - Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our management concluded that, as of December 31, 2025, our internal control over financial reporting was effective.

Deloitte & Touche LLP (PCAOB ID No. 34), an independent registered public accounting firm, which has audited and reported on the consolidated financial statements contained in this Form 10-K, has issued its report on the effectiveness of the Company's internal control over financial reporting which follows this report.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the shareholders and the Board of Directors of Avantor, Inc.

**Opinion on Internal Control over Financial Reporting**

We have audited the internal control over financial reporting of Avantor, Inc. and subsidiaries (the "Company") as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 11, 2026, expressed an unqualified opinion on those financial statements.

**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's Annual Report on Internal Control Over Financial Reporting. 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 included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the stockholders and the Board of Directors of Avantor, Inc.

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Avantor, Inc. and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income or loss, stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also 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, 2025, 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 11, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's 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 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter**

The critical audit matter communicated below is a matter arising from the current-period audit of the 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 financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.

**Goodwill Impairment - Distribution reporting unit - Refer to notes 2, 6, and 11 to the financial statements**

------

*Critical Audit Matter Description*

Goodwill is tested for impairment at the reporting unit level on October 1 of each year or more frequently whenever an event or change in circumstance occurs that would require reassessment of the recoverability of the asset. The Company estimates the fair value of each reporting unit using a weighted average of two valuation methods based on a discounted cash flows method and a guideline public company method. These valuation methods require management to make various assumptions, which include, but are not limited to, future profitability, cash flows, discount rates, weighting of valuation methods, and the selection of comparable publicly traded companies (peer groups). If the Company determines the carrying value of a reporting unit exceeds its fair value, an impairment charge is recorded for the excess. As a result of sustained decreases in the Company's publicly quoted share price and market capitalization as well as changes in the operating results of the Distribution reporting unit, the Company conducted an interim impairment test as of September 30, 2025, which resulted in a non-cash goodwill impairment charge of $785.0 million. No impairment charges were recorded to the other reporting units as their estimated fair values exceeded their respective carrying amounts.

The principal considerations for our determination that performing audit procedures relating to the Distribution reporting unit's goodwill impairment analysis is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the reporting unit; (ii) a high degree of auditor judgment in evaluating the reasonableness of management's assumptions under the discounted cash flows method, in particular the estimates of net sales growth and the discount rate; and (iii) an increased extent of effort, including the need to involve our fair value specialists.

*How the Critical Audit Matter Was Addressed in the Audit*

Our audit procedures over management's estimates of net sales growth and the discount rate for the Distribution reporting unit included the following, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We tested the effectiveness of controls over management's goodwill impairment testing, including those over management's assumptions of net sales growth and the discount rate under the discounted cash flows method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We evaluated management's ability to accurately forecast net sales growth by comparing actual results to management's historical forecasts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We evaluated the reasonableness of management's net sales growth by comparing the forecast to historical results and forecasted information included in available peer and industry data.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• With the assistance of our fair value specialists, we evaluated the reasonableness of the discount rate, by (1) testing the underlying information supporting this assumption; (2) testing the mathematical accuracy of the calculations; and (3) developing a range of independent estimates and comparing those to the discount rate selected by management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We evaluated the competency and objectivity of management's specialists who assisted with preparing the discounted future cash flows analysis.

*The accompanying notes are an integral part of these consolidated financial statements*

**Avantor, Inc. and subsidiaries**

**Notes to consolidated financial statements**

**1.&nbsp;&nbsp;&nbsp;&nbsp;Nature of operations and presentation of financial statements**

We are a global manufacturer and distributor that provides products and services to customers in the biopharmaceutical, healthcare, education & government and advanced technologies & applied materials industries.

***Basis of presentation***

The accompanying financial statements have been prepared in accordance with the rules and regulations of the SEC for annual reports and GAAP. The financial statements include the accounts of Avantor, Inc., its consolidated subsidiaries, and those business entities in which we maintain a controlling interest.

***Principles of consolidation***

All intercompany balances and transactions have been eliminated from the financial statements.

***Use of estimates***

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported throughout the financial statements. Actual results could differ from those estimates.

**2.&nbsp;&nbsp;&nbsp;&nbsp;Summary of significant accounting policies**

***Earnings per share***

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the reporting period.

Diluted earnings per share is computed based on the weighted average number of common shares outstanding increased by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued and reduced by the number of shares we could have repurchased with the proceeds from the issuance of the potentially dilutive shares. In the event that preferred shares are issued and outstanding, preferred dividends are added back to net income available to common stockholders, provided that inclusion of the preferred securities is not anti-dilutive.

***Segment reporting***

Effective January 1, 2024, we changed our operating model and reporting segment structure from three reportable segments to two reportable segments: Laboratory Solutions and Bioscience Production. This structure aligns with how our Chief Executive Officer, who is our CODM, measures segment operating performance and allocates resources across our operating segments.

None of our customers contributed more than 5% to our net sales, and we disclose net sales for the following product categories: proprietary and third-party.

We disclose geographic data for our largest country, the United States, as a percentage of consolidated net sales. No other countries were individually material. We disclose property and equipment by geographic

------

area because many of these assets cannot be readily moved and are illiquid, subjecting them to geographic risk. None of our other long-lived assets are subject to significant geopolitical risk. We do not manage total assets on a segment basis and as a result the Company does not report asset information by segment. Segment information about interest expense, income tax expense or benefit and other significant non-cash items other than depreciation and amortization, are not disclosed because they are not included in the segment profitability measurement nor are they otherwise provided to our CODM on a regular basis.

***Cash and cash equivalents***

Cash equivalents are comprised of highly-liquid investments with original maturities of three months or less. Bank overdrafts are classified as current liabilities, and changes to bank overdrafts are presented as a financing activity on our consolidated statements of cash flows.

***Accounts receivable and allowance for current expected credit losses***

Substantially all of our accounts receivable are trade accounts that are recorded at the invoiced amount and generally do not bear interest. Accounts receivable are presented net of an allowance for current expected credit losses. We consider many factors in estimating our allowance including the age of our receivables, historical collections experience, customer types, creditworthiness and economic trends. Account balances are written off against the allowance when we determine it is probable that the receivable will not be recovered.

***Inventory***

Inventory consists of merchandise inventory related to our distribution business and finished goods, raw materials and work in process related to our manufacturing business. Goods are removed from inventory as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Merchandise inventory purchased by certain U.S. subsidiaries using the last-in, first-out method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All other merchandise inventory using the first-in, first-out method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Manufactured inventories using an average cost method.

Inventory is valued at the lower of cost or net realizable value. Cost for manufactured goods is determined using standard costing methods to estimate raw materials, labor and overhead consumed. Variances from actual cost are recorded to inventory at period-end. Cost for other inventory is based on amounts invoiced by suppliers plus freight. If net realizable value is less than carrying value, we reduce the carrying amount to net realizable value and record a loss in cost of sales.

***Property, plant and equipment***

Property, plant and equipment are stated at cost. Depreciation is recognized using the straight-line method over estimated useful lives of ten to forty years for buildings and related improvements, three to ten years for machinery and equipment and three to fifteen years for capitalized software. Leasehold improvements are depreciated on a straight-line basis over the shorter of the estimated useful lives of the assets or the estimated remaining life of the lease. Depreciation is classified as cost of sales or SG&A expense based on the nature of the underlying asset.

------

Software development costs are capitalized as property, plant and equipment once the preliminary project stage is completed and management commits to funding the project if it is probable that the project will be completed for its intended use. Preliminary project planning and training costs related to software are expensed as incurred.

***Impairment of long-lived assets***

Long-lived assets include property, plant and equipment, finite-lived intangible assets and certain other assets. For impairment testing purposes, long-lived assets may be grouped with working capital and other types of assets or liabilities if they generate cash flows on a combined basis.

We evaluate long-lived assets or asset groups for impairment whenever events or changes in circumstances indicate a potential inability to recover their carrying amounts. Impairment is determined by comparing their carrying value to their estimated undiscounted future cash flows. If long-lived assets or asset groups are impaired, the loss is measured as the amount by which their carrying values exceed their fair value.

***Goodwill and other intangible assets***

Goodwill represents the excess of the price of an acquired business over the aggregate fair value of its identifiable net assets. Other intangible assets consist of both finite-lived and indefinite-lived intangible assets.

Goodwill and other indefinite-lived intangible assets are tested annually for impairment on October 1 of each year and whenever an impairment indicator arises. Goodwill impairment testing is performed at the reporting unit level.

As described above, we reorganized our segment reporting structure effective January 1, 2024. The segment reporting reorganization also resulted in a change to our reporting units for the purpose of goodwill impairment testing. As a result of the reorganization, our goodwill was reassigned to reporting units affected using a relative fair value approach similar to that used when a portion of a reporting unit is disposed of, to the new reporting units making up our Laboratory Solutions and Bioscience Production reporting segments.

Our finite-lived intangible assets are tested for impairment whenever an impairment indicator arises. Examples of impairment indicators include unexpected adverse business conditions, economic factors, unanticipated technological changes or competitive activities, loss of key personnel and acts or anticipated acts by governments and courts.

The impairment analysis for goodwill and indefinite-lived intangible assets consists of an optional qualitative assessment potentially followed by a quantitative analysis. If we determine that the carrying value of a reporting unit or an indefinite-lived intangible asset exceeds its fair value, an impairment charge is recorded for the excess.

Indefinite-lived intangible assets are not amortized. Annually, we evaluate whether these assets continue to have indefinite lives, considering whether they have any legal, regulatory, contractual, competitive or economic limitations and whether they are expected to contribute to the generation of cash flows indefinitely.

------

Finite-lived intangible assets are amortized over their estimated useful lives on a straight-line basis, with customer relationships amortized over lives of ten to twenty years, tradenames amortized over lives of ten to fifteen years and other finite-lived intangible assets amortized over lives of five to twenty years. Amortization is classified in SG&A expenses. We reevaluate the estimated useful lives of our finite-lived intangible assets annually.

***Restructuring and severance charges***

Restructuring plans are designed to improve gross margins and reduce operating costs over time. We typically incur up-front charges to implement these plans related to employee severance, facility closure and other actions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Employee severance and related* — Employee severance programs can be voluntary or involuntary. Voluntary severances are recorded at their reasonably estimated amount when associates accept severance offers. Involuntary severances covered by plan or statute are recorded at estimated amounts when probable and reasonably estimable. Judgment is required to determine probability and whether the amount can be reasonably estimated. Involuntary severances requiring significant continuing service are measured at fair value as of the termination date and recognized on a straight-line basis over the service period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Facility closure* — On the date we cease using a facility, facility leased assets are tested for impairment in the same way as other long-lived assets. The remaining lease expense is recognized between the period that we commit to cease use of a facility and the date we exit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Other* — Other charges may be incurred to write down assets, divest businesses or for other reasons and are accounted for under applicable GAAP as described elsewhere in these policies.

Restructuring and severance charges are classified as SG&A expenses or cost of sales depending on the nature of the expense. Accrued restructuring and severance charges are classified as employee-related or current liabilities if we anticipate settlement within one year, otherwise they are included in other liabilities.

***Contingencies***

Our business exposes us to various contingencies including compliance with environmental laws and regulations, legal exposures related to the manufacture and sale of products and other matters. Loss contingencies are reflected in the financial statements based on our assessments of their expected outcome or resolution:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They are recognized as liabilities on our balance sheet if the potential loss is probable and the amount can be reasonably estimated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They are disclosed if the potential loss is material and considered at least reasonably possible.

Significant judgment is required to determine probability and whether the amount can be reasonably estimated. Due to uncertainties related to these matters, accruals are based only on the information available at the time. As additional information becomes available, we reassess potential liabilities and may revise our previous estimates.

------

***Debt***

Borrowings under lines of credit are stated at their face amount. Borrowings under term debt and through the issuance of notes are stated at their face amounts net of unamortized deferred financing costs, including any original issue discounts or premiums.

The accounting for financing costs depends on whether debt is newly issued, extinguished or modified. That determination is made on an individual lender basis when the lenders are part of a syndication. When new debt is issued, financing costs and discounts are deferred and recognized as interest expense through maturity of the debt. When debt is extinguished, unamortized deferred financing costs and discounts are written off and presented as a loss on extinguishment of debt. When debt is modified, new financing costs and prior unamortized deferred financing costs may be either (i) immediately recognized as interest expense, other expense, or SG&A expense or (ii) deferred and recognized as interest expense through maturity of the modified debt, depending on the type of cost and whether the modification was substantial or insubstantial.

Borrowings and repayments under lines of credit are short-term in nature and presented on the statement of cash flows on a net basis.

***Equity***

Stockholders' equity or deficit comprises common stock and treasury stock. Our accounting policies for these instruments are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Common stock is presented at par value plus additional paid-in amounts, net of issuance costs. Distributions are accounted for as reductions to common stock including paid-in capital and are classified as financing activities on the statement of cash flows.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Upon issuance, paid-in capital is allocated among host stock instruments on a relative fair value basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Treasury stock is accounted for under the cost method. When shares are repurchased, the cost of the shares, including any related transaction costs, is recorded as a reduction of stockholders' equity. Shares held in treasury are excluded from common shares outstanding and therefore reduce the weighted-average number of shares outstanding used in the calculation of both basic and diluted earnings per share. When treasury shares are reissued, the difference between the reissuance price and the recorded cost of those shares is recognized in additional paid-in capital.

Costs directly associated with new equity issuances are recorded as other current assets until the issuances are completed or abandoned. If the issuance is completed, the costs are reclassified to stockholders' equity and presented as a reduction of proceeds received. If the issuance is abandoned, the costs are reclassified to SG&A expenses. Costs associated with secondary equity offerings under a registration rights agreement are recorded as SG&A expenses.

Disclosures about certain classes of stock are provided in the footnotes and not stated separately on the balance sheet or statement of stockholders' equity when those presentations are not deemed to be material.

------

***Revenue recognition***

We recognize revenue by applying a five-step process: (i) identify the contract with a customer, (ii) identify the performance obligation in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue as the performance obligations are satisfied by transferring control of the performance obligation through delivery of a promised product or service to a customer.

Control of a performance obligation may transfer to the customer either at a point in time or over time depending on an evaluation of the specific facts and circumstances for each contract, including the terms and conditions of the contract as agreed with the customer, as well as the nature of the products or services to be provided. The substantial majority of our net sales are recognized at a point in time based upon the delivery of products to customers pursuant to purchase orders. We recognize service revenues and sales of certain of our custom-manufactured products over time as control passes to the customer concurrent with our performance. We are able to fulfill most purchase orders rapidly, and service and custom-manufacturing cycles are short. As a result, we do not record material contract assets or liabilities, nor do we have material unfulfilled performance obligations.

We have elected to use the practical expedient not to adjust the transaction price of a contract for the effects of a significant financing component if, at the inception of the contract, we expect that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will be one year or less.

Some customer contracts include variable consideration, such as rebates and prebates, some of which depend upon our customers meeting specified performance criteria, such as a purchasing level over a period of time. We use judgment to estimate the value of these pricing arrangements at each reporting date and record contract assets or liabilities to the extent that estimated values are recognized at a different time than the revenue for the related products. When estimating variable consideration, we also apply judgment when considering the probability of whether a reversal of revenue could occur and only recognize revenue subject to this constraint.

The only significant costs we incur to obtain contracts are related to sales commissions. These commissions are primarily based on purchase order amounts, not recoverable and not applicable to periods greater than one year. We elected to apply the practical expedient to expense these costs as incurred as if the amortization period of the asset that would have otherwise been recognized is one year or less.

Performance obligations following the delivery of products, such as rights of return and warranties, are not material. No other types of revenue arrangements were material to our consolidated financial statements.

***Classification of expenses — cost of sales***

Cost of sales includes the cost of the product, depreciation of production assets, supplier rebates, shipping and receiving charges and inventory adjustments. For manufactured products, the cost of the product includes direct and indirect manufacturing costs, plant administrative expenses and the cost of raw materials consumed in the manufacturing process.

------

***Classification of expenses — selling, general and administrative***

Selling, general and administrative expenses include personnel and facility costs, amortization of intangible assets, depreciation of non-production assets, research and development costs, advertising expense, promotional charges and other charges related to our global operations. Research and development expenses were not material for the periods presented.

***Employee benefit plans***

Some of our employees participate in defined benefit plans that we sponsor. We present these plans as follows due to their differing geographies, characteristics and actuarial assumptions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *U.S. plans* — Our U.S. plans are closed to participants who joined the Company after 2018, and annual accruals of future pension benefits for participating employees are not material to our financial statements. One of our two U.S. plans was terminated during 2025, as discussed in note 17.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Non-U.S. plans* — We sponsor eight plans covering employees in various countries that we acquired from VWR in 2017. Most of these plans continue to accrue future pension benefits for participating employees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Medical plan* — We provide a post-retirement medical plan for certain U.S. employees. The plan is closed to new employees, and annual accruals of future pension benefits for participating employees are not material to our financial statements.

We sponsor a number of other defined benefit plans in various countries that are not material individually or in the aggregate and therefore are not included in our disclosures. Defined contribution and other employee benefit plans are also not material.

The cost of our defined benefit plans is incurred systematically over expected employee service periods. We use actuarial methods and assumptions to determine expense each period and the value of projected benefit obligations. Actuarial changes in the projected value of defined benefit obligations are deferred to AOCI and recognized in earnings systematically over future periods. The portion of cost attributable to continuing employee service is included in SG&A expenses. The rest of the cost is included in other income or expense, net.

***Stock-based compensation expense***

Some of our management and directors are compensated with stock-based awards. Stock-based compensation expense is included in SG&A expenses on the statement of operations.

*Stock options and RSUs*

We measure the expense of stock options and RSUs based on their grant-date fair values. Awards that vest based on continued service are recognized as compensation expense on a straight-line basis over the requisite service period. For awards that are contingent upon the achievement of a performance condition, compensation expense is recognized over the performance period based on the probability of achievement. Awards with market conditions are measured at grant-date fair value using valuation techniques that incorporate the likelihood of achieving the market condition, and the resulting expense is recognized over the requisite service period regardless of whether the market condition is ultimately

------

satisfied. We recognize forfeitures of unvested awards as they occur by reversing any expense previously recorded in the period of forfeiture. Upon exercise or vesting of awards, we issue new shares of common stock.

The grant-date fair value of stock options is measured using the Black-Scholes pricing model, which incorporates assumptions based on the terms of each stock option agreement, the expected behavior of grant recipients, and our own and selected peer company data. Through the year ended December 31, 2024, due to limited trading history, we estimated volatility using a peer group methodology over a period equal to the expected life of the stock options. Beginning in 2025, after sufficient trading history became available, we adopted a blended volatility methodology that combines Avantor's historical volatility with that of a peer group to provide a more stable and representative input. The risk-free interest rate is based on U.S. Treasury observed market rates, continuously compounded over the expected life. The expected life of stock options is estimated as the midpoint between the weighted-average vesting period and the contractual term.

The grant-date fair value for RSUs in which the vesting condition is based only on continuing service is measured using the quoted closing price of our common stock on the grant date. The grant-date fair value of awards with performance conditions is also measured using the quoted closing price of our common stock on the grant date, adjusted for the probability of achieving the specified performance targets. For awards that contain market conditions, we determine the grant-date fair value using a Monte Carlo valuation model.

*Award modifications*

When stock-based compensation arrangements are modified, we treat the modification as an exchange of the original award for a new award and immediately recognize expense for the incremental value of the new award. The incremental value is measured as the excess of the fair value of new awards over the fair value of the original awards, each based on circumstances and assumptions as of the modification date. Fair value is measured using the same methods previously described. We have not had any such modifications for the periods presented in these financial statements.

***Income taxes***

Our worldwide income is subject to the income tax regulations of many governments. Income tax expense is calculated using an estimated global rate with recognition of deferred tax assets and liabilities for expected temporary differences between taxable and reported income. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income when those temporary differences are expected to reverse. We record a valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized.

Income tax regulations change from time to time. The effect of a change in tax law on deferred tax assets and liabilities is recognized as a cumulative adjustment to income tax expense or benefit in the period of enactment. The effect of a change in tax law on the income tax expense or benefit itself is recognized prospectively for the applicable tax years.

Income tax regulations can be complex, requiring us to interpret tax law and take positions. Upon audit, tax authorities may challenge our positions. We regularly assess the outcome of potential examinations and only recognize positions that are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is more likely than not of being realized. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs, as a result

------

of information that arises or when a tax position is effectively settled. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of interest expense in our consolidated financial statements.

***Fair value measurements***

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. We classify fair value measurements based on the lowest of the following levels that is significant to the measurement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Level 1* — Quoted prices in active markets for identical assets or liabilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Level 2* — Inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Level 3* — Inputs that are unobservable for the asset or liability based on our evaluation of the assumptions market participants would use in pricing the asset or liability

We exercise considerable judgment when estimating fair value, particularly when evaluating what assumptions market participants would likely make. The use of different assumptions or estimation methodologies could have a material effect on the estimated fair values.

***Foreign currency translation***

Our operations span the globe, so we are impacted by changes in foreign currency exchange rates. We determine the functional currency of our subsidiaries based upon the primary currency used to generate and expend cash, which is usually the currency of the country in which the subsidiary is located. For subsidiaries with functional currencies other than the U.S. dollar, assets and liabilities are translated into U.S. dollars using period-end exchange rates, and revenues, expenses, income and losses of our subsidiaries are translated into U.S. dollars using monthly average exchange rates. The resulting foreign currency translation gains or losses are deferred as AOCI and reclassified to earnings only upon sale or liquidation of those businesses.

Gains and losses related to the remeasurement of debt and intercompany financing into functional currencies are reported in earnings as other income or expense, net. When foreign currency-denominated debt is designated as a hedge of our net investments in non-U.S denominated subsidiaries, gains and losses are reported in AOCI as part of the cumulative translation adjustment. Gains and losses associated with the remeasurement of operating assets and liabilities into functional currencies are reported within the applicable component of operating income.

***Leases***

We primarily enter into real estate leases for manufacturing, warehousing and commercial office space to support our global operations. We also enter into vehicle and equipment leases to support those operations.

We determine if an arrangement is a lease at inception. Short-term leases, defined as having an initial term of twelve months or less, are expensed as incurred and not recorded on the balance sheet. We record the value of all other leased property and the related obligations as assets and liabilities on the balance sheet. Information about the amount and classification of lease assets and liabilities is included in note 23.

------

At inception, lease assets and liabilities are measured at the present value of future lease payments over the lease term. As most of our leases do not provide an implicit rate, we exercise judgment in selecting the incremental borrowing rate based on the information available at inception to determine the present value of future payments. Operating lease assets are further adjusted for lease incentives and initial direct costs.

Our lease terms may include options to extend or terminate the lease. We exercise judgment to calculate the term of those leases when extension or termination options are present and include such options in the calculation of the lease term when it is reasonably certain that we will exercise those options. Operating lease expense is recognized on a straight-line basis over the lease term, except for variable rent which is expensed as incurred. Short-term lease and variable rent expense was immaterial to the financial statements and has been included within operating lease expense. Finance lease expense includes depreciation, which is recognized on a straight-line basis over the expected life of the leased asset and interest expense.

Some of our lease agreements include both lease and non-lease components. We account for those components separately for real estate leases and as a combined single lease component for all other types of leases.

***Business combinations***

We account for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in our consolidated results as of the acquisition date and the purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. Any excess of the fair value consideration transferred over the estimated fair values of the identifiable net assets acquired is recognized as goodwill.

Any purchase price that is considered contingent consideration is measured at its estimated fair value at the acquisition date. Contingent consideration is remeasured at the end of each reporting period, with changes in estimated fair value being recorded through SG&A expense within our statement of operations.

***Derivatives and hedging***

We use derivative instruments primarily to manage currency exchange and interest rate risks and recognize them as either assets or liabilities which are measured at fair value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cash flow hedges* — We use interest rate derivatives to add stability to interest expense and to manage our exposure to interest rate movements. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is recorded in AOCI and reclassified into earnings in the same period(s) during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Net Investment hedges* — We use foreign currency-denominated debt and cross-currency swaps to hedge our net investments in foreign operations against adverse movements in exchange rates. For derivatives designated as net investment hedges, the gain or loss on the derivative is reported in AOCI as part of the cumulative translation adjustment. Amounts are reclassified out of AOCI into earnings in the event the hedged net investment is either sold or substantially liquidated.

**3.&nbsp;&nbsp;&nbsp;&nbsp;New accounting standards**

***Income Taxes***

In December 2023, the FASB issued ASU 2023-09, *Improvements to Income Tax Disclosures*, which amends the existing income taxes guidance (ASC Topic 740) to require additional disclosures surrounding annual rate reconciliation, income taxes paid and other income tax related disclosures.

The amendments in this update are effective for annual periods beginning after December 15, 2024. Accordingly, we adopted this standard on a retrospective basis within our annual report for the year ended December 31, 2025. Adoption resulted in expanded disclosures within our income tax footnote, primarily related to the annual effective tax rate reconciliation and income taxes paid. Refer to note 20 for these disclosures.

***Disaggregation of Income Statement Expenses (DISE)***

In November 2024, the FASB issued ASU 2024-03, *Disaggregation of Income Statement Expenses (DISE)*, requiring additional disclosure of the nature of expenses included in the income statement. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses.

The amendments in this update are effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the impact of our pending adoption of this standard on our financial statements.

***Other***

There were no other new accounting standards that we expect to have a material impact on our financial position or results of operations upon adoption.

***Adoption of rules to enhance and standardize climate-related disclosures for Investors***

In March 2024, the SEC adopted final rules to enhance and standardize climate-related disclosures in registration statements and annual reports. On April 4, 2024, the SEC voluntarily stayed the effectiveness of these rules pending judicial review, and on March 27, 2025, the SEC withdrew its defense of the rules in ongoing litigation. As a result, the rules remain subject to a stay and their future applicability is uncertain. We continue to monitor developments and will evaluate the impact of any final requirements on our disclosures and related processes.

**4.&nbsp;&nbsp;&nbsp;&nbsp;Divestitures**

We completed the sale of our Clinical Services business, a component of the Company's Laboratory Solutions reportable segment, on October 17, 2024. In the fourth quarter of 2024, we received gross proceeds of approximately $595.0 million. In connection with the sale, we recorded a gain of $446.6 million in the consolidated statements of operations for the year ended December 31, 2024. During the year ended December 31, 2025, we recorded a $(5.1) million post-closing purchase price adjustment to the originally recognized gain on sale in the consolidated statements of operations. The Clinical Services business was not classified as a discontinued operation because it did not represent a strategic shift that would have a major effect on our operations or financial results.

**5.&nbsp;&nbsp;&nbsp;&nbsp;Earnings per share**

The following table presents the reconciliation of basic and diluted (loss) earnings per share for the years ended December 31, 2025, 2024 and 2023:

---

Certain stock options and RSUs are not included in the diluted earnings (loss) per share calculation when the effect would have been anti-dilutive. The number of anti-dilutive shares not included were 14.5 million, 5.9 million and 12.9 million for the year ended December 31, 2025, December 31, 2024 and December 31, 2023, respectively.

**6.&nbsp;&nbsp;&nbsp;&nbsp;Risks and uncertainties**

***Remeasurement of foreign-denominated debt and intercompany borrowings***

Our operations span the globe. To fund those operations, we have entered into significant Euro-denominated indebtedness (see note 14), and we have also established intercompany borrowings among our subsidiaries that are denominated in various currencies. Changes in foreign currency exchange rates, particularly the Euro, have required us to record gains and losses, some of which have been significant, to remeasure the debt and the intercompany borrowings into functional currencies of the subsidiaries holding them.

Our intercompany capitalization structure and derivative and hedging instruments are intended to mitigate substantially all of our net Euro financing exposure in future periods. We expect to record gains and losses related to intercompany borrowings denominated in other currencies. Historically, the remeasurement of borrowings denominated in currencies other than the Euro has not been material.

***Impairment testing***

On January 1, 2024, in connection with the Company's reporting segment structure change, we performed quantitative impairment testing of goodwill for each of our reporting units. We did not record any impairment charges as each reporting unit had a fair value that was in excess of its carrying value.

As a result of sustained decreases in our publicly quoted share price and market capitalization, as well as changes in the operating results of our Distribution reporting unit, formerly referred to as our Buy Sell Lab reporting unit, we conducted an interim goodwill impairment test as of September 30, 2025. Based on this test, the carrying amount of the Distribution reporting unit exceeded its fair value, resulting in a non-deductible, non-cash goodwill impairment charge of $785.0 million, recorded in the consolidated

------

statements of operations for the three months ended September 30, 2025. Following the impairment, the carrying value of the Distribution reporting unit equals its estimated fair value.

Future goodwill impairment charges may be required if market conditions, projected operating results, or other key valuation assumptions deteriorate. Changes in forecasted results, discount rates, or other inputs used to estimate fair value could materially impact valuations and increase the risk of impairment in subsequent periods. We did not record any goodwill impairments during the years ended December 31, 2024 and December 31, 2023.

***Collective bargaining arrangements***

As of December 31, 2025, approximately 5% of our employees in North America were represented by unions, and a majority of our employees in Europe are represented by workers' councils or unions.

**7.&nbsp;&nbsp;&nbsp;&nbsp;Segment financial information**

Effective January 1, 2024, we changed our operating model and reporting segment structure into two reportable business segments: Laboratory Solutions and Bioscience Production. Corporate costs are managed on a standalone basis, certain of which are allocated to our reportable segments.

In connection with this change, our CODM changed the measure used to evaluate segment profitability from Adjusted EBITDA to Adjusted Operating Income. The CODM uses this metric predominantly in the annual budget, forecasting and performance monitoring processes. All segment disclosures for 2023 reflect the changes to our reportable segments.

The following tables present information by reportable segment:&nbsp;&nbsp;&nbsp;&nbsp;

Depreciation expense was $109.1 million in 2025, $105.7 million in 2024 and $94.6 million in 2023.

In the second quarter of 2023, persistently high customer inventory in the end markets served by Ritter and an overall slowdown in research activity caused Ritter's revenue to decline compared to prior expectations. Due to these circumstances, we performed an impairment test of the Ritter asset group, which resulted in a fair value that was lower than its carrying value. As a result, we recorded an impairment charge of $54.4 million on Ritter's property, plant & equipment in the second quarter of 2023. This charge impacted our Laboratory Solutions reportable segment.

Our impairment test was performed as of June 30, 2023 and utilized our then latest estimates of Ritter's projected cash flows, including revenues, gross margin, SG&A expenses, capital expenditures to maintain the acquired assets, and investments in debt free net working capital, as well as current market assumptions for the discount rate.

As described in note 2, we reorganized our segment reporting structure effective January 1, 2024. The segment reporting reorganization also resulted in a change to our reporting units for the purpose of goodwill impairment testing. Our reporting units are Distribution (formerly referred to as Buy Sell Lab), Laboratory Specialty Products (formerly referred to as Proprietary Lab), Laboratory Services (formerly referred to as Services), Manufactured Products, Controlled Environment Consumables (formerly referred to as Buy Sell Production), and NuSil. As a result of the reorganization, our goodwill was reassigned to the new reporting units making up our Laboratory Solutions and Bioscience Production reporting segments.

We reassigned goodwill as of January 1, 2024 to align to our new segment structure by using a relative fair value approach as required under GAAP. We tested goodwill for impairment immediately before and after the reorganization of our reporting structure; no impairment was identified.

The following table presents goodwill by our reportable segments, on the effective date of the change:

---

| | | | |
|:---|:---|:---|:---|
| | **Laboratory Solutions** | **Bioscience Production** | **Total** |
| Goodwill, gross | $3842.0 | $1913.5 | $5755.5 |
| Accumulated impairment losses | (18.4) | (20.4) | (38.8) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Goodwill, net | $3823.6 | $1893.1 | $5716.7 |

---

As described in note 6, as a result of sustained decreases in our publicly quoted share price and market capitalization as well as changes in the operating results of our Distribution reporting unit, we conducted an interim test of our goodwill as of September 30, 2025.

We estimate the fair value of reporting units using a weighted average of two valuation methods based on a discounted cash flows method and a guideline public company method. These valuation methods require management to make various assumptions, including, but not limited to, future profitability, cash flows, including revenues, gross margin, SG&A expenses, capital expenditures, and investments in debt free net working capital, current market assumptions for the discount rates, weighting of valuation methods and the selection of comparable publicly traded companies. Variations in any of these assumptions could result in materially different calculations of fair value.

Based on the results of the impairment test, the carrying amount of our Distribution reporting unit exceeded its fair value, resulting in a non-deductible, non-cash goodwill impairment charge of $785.0 million, which was recorded in the consolidated statement of operations. We did not identify impairment of any other long-lived assets in this reporting unit. The remaining reporting units tested were not impaired, as their estimated fair values exceeded their respective carrying amounts as of the interim testing date.

Following the impairment charge, the carrying value of the Distribution reporting unit is equal to its estimated fair value. Recognition of additional impairment charges may be required in future periods if market conditions, projected results, or other valuation assumptions deteriorate further.

Since October 1, 2025 is our designated annual impairment testing date, management performed the required procedures to reassess impairment as of that date, including a review of key assumptions, market

indicators, and other relevant factors. No conditions were identified that differed materially from those considered in the September 30, 2025 interim analysis. Accordingly, the conclusions reached in that interim test remained appropriate, and no additional impairment was recorded as of October 1, 2025.

1. As of December 31, 2025 and December 31, 2024, accumulated impairment losses on Customer relationships were $65.9 million and on Other were $40.5 million, totaling $106.4 million.

------

Amortization expense was $301.1 million in 2025, $299.8 million in 2024 and $307.7 million in 2023.

We recorded an impairment charge of $106.4 million on Ritter's finite-lived intangible assets in the second quarter of 2023 in connection with the impairment of Ritter's property, plant & equipment, as previously discussed in note 10. This charge impacted our Laboratory Solutions reportable segment.

---

Restructuring and severance charges are classified as SG&A expenses or cost of sales depending on the nature of the expense.

**2024 restructuring program**

The 2024 restructuring program is a part of the Company's multi-year cost transformation initiative designed to right-size the Company's cost base and optimize its footprint and organizational structure with a focus on driving cost improvement and productivity. During 2025, we recognized a $(5.3) million non-cash adjustment that reduced the previously recorded 2024 restructuring accrual, primarily reflecting updates to expected severance and other exit costs that were no longer required. No additional material charges were incurred in 2025, and we do not expect to incur additional material charges related to this program in future periods.

**13.&nbsp;&nbsp;&nbsp;&nbsp;Commitments and contingencies**

Our business involves commitments and contingencies related to compliance with environmental laws and regulations, the manufacture and sale of products and litigation. The ultimate resolution of contingencies is subject to significant uncertainty, and it is reasonably possible that contingencies could be decided unfavorably against us.

***Environmental laws and regulations***

Our environmental liabilities are subject to changing governmental policy and regulations, discovery of unknown conditions, judicial proceedings, method and extent of remediation, existence of other potentially responsible parties and future changes in technology. We believe that known and unknown environmental matters, if not resolved favorably, could have a material effect on our financial position, liquidity and profitability. Matters to be disclosed are as follows:

------

*Mallinckrodt indemnification*

In 2010, New Mountain Capital acquired us from Covidien plc in accordance with a stock purchase agreement dated May 25, 2010. At that time, we were organized as Mallinckrodt Baker, Inc. or MBI. Pursuant to the terms of that agreement, we are entitled to various levels of indemnification with respect to environmental liabilities involving the former MBI operations. In 2013, in connection with the Covidien plc divestiture of Mallinckrodt Group S.a.r.l and Mallinckrodt LLC, together "Mallinckrodt," and by a second amendment to the stock purchase agreement dated June 6, 2013, but effective upon the consummation of the divestiture, Covidien plc assigned its obligations as described herein to Mallinckrodt, and Mallinckrodt assumed those obligations from Covidien plc subject to a continuing guarantee by Covidien International Finance, S.A ("CIFSA"). As a result of the stock purchase agreement and assignment, Mallinckrodt is contractually obligated to indemnify and defend us for all off-site environmental liabilities (for example, Superfund or CERCLA liabilities) arising from the pre-closing disposal of chemicals or wastes by former MBI operations.

In connection with environmental liabilities arising from pre-closing noncompliance with environmental laws, Mallinckrodt became contractually obligated to reimburse us for a percentage of the total liability, with such reimbursements made through disbursements from a $30.0 million environmental escrow established at the time of the closing. Specifically, Mallinckrodt became responsible for reimbursement of 80% of the total costs up to $40.0 million of such environmental liabilities. Mallinckrodt became responsible for reimbursement of 50% of the next $40.0 million of such environmental liabilities. If such environmental liabilities exceed $80.0 million in the aggregate, Mallinckrodt became responsible for reimbursement of 100% of such liabilities up to the next $30.0 million in the aggregate. Currently, reimbursements are 80% of the amounts spent by us, with reimbursements and settlements to date exceeding $12.0 million. In addition, in connection with operation and maintenance activities required pursuant to administrative consent orders and subsequently issued remedial action permits involving our Phillipsburg, New Jersey, facility, amounts in excess of a small annual threshold are also subject to reimbursement, currently at the 80% level.

In 2023, Mallinckrodt initiated bankruptcy proceedings under Chapter 11 of the Bankruptcy Code and notified us that it was seeking to reject the 2010 stock purchase agreement and its obligations thereunder. As noted above, Mallinckrodt's obligations under the 2010 stock purchase agreement were guaranteed by CIFSA, who has agreed to honor its indemnity obligations going forward.

*Other noteworthy matters*

The New Jersey Department of Environmental Protection has ordered us to remediate groundwater conditions near our plant in Phillipsburg, New Jersey. This matter is covered by the indemnification arrangement previously described. At December 31, 2025, our accrued obligation under this order is $2.3 million, which is calculated based on expected cash payments discounted at rates ranging from 3.4% to 4.8% between 2026 and 2045. The undiscounted amount of that obligation is $3.5 million.

In 2016, we assessed the environmental condition of our chemical manufacturing site in Gliwice, Poland. Our assessment revealed specific types of soil and groundwater contamination throughout the site. We are also monitoring the condition of a closed landfill on that site. These matters are not covered by our indemnification arrangement because they relate to an operation we subsequently acquired. At December 31, 2025, our balance sheet includes a liability of $1.2 million for remediation and monitoring costs. That liability is estimated primarily on discounted expected remediation payments and is not materially different from its undiscounted amount.

------

***Manufacture and sale of products***

Our business involves risk of product liability, patent infringement and other claims in the ordinary course of business arising from the products that we produce ourselves or obtain from our suppliers, as well as from the services we provide. Our exposure to such claims may increase to the extent that we expand our manufacturing operations or service offerings.

We maintain insurance policies to protect us against these risks, including product liability insurance. In many cases the suppliers of products we distribute have indemnified us against such claims. Our insurance coverage or indemnification agreements with suppliers may not be adequate in all pending or any future cases brought against us. Furthermore, our ability to recover under any insurance or indemnification arrangements is subject to the financial viability of our insurers, our suppliers and our suppliers' insurers, as well as legal enforcement under the local laws governing the arrangements.

We have entered into indemnification agreements with customers of our self-manufactured products to protect them from liabilities and losses arising from our negligence, willful misconduct or sale of defective products. To date, we have not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions.

***Litigation***

The Company and certain current and former officers and directors have been named as defendants in two putative securities class action lawsuits filed in the United States District Court for the Eastern District of Pennsylvania on October 30, 2025, and November 25, 2025, respectively. The complaints allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act and Rule 10b-5 related to alleged misleading or false statements concerning Avantor's competitive position and the purported effects of increased competition, as well as other aspects of the Company's business, operations, and management. The lawsuits seek unspecified damages, attorneys' fees, and other relief. The Company disputes the claims and intends to vigorously defend against them.

At this time, the outcome of this matter cannot be predicted, and management cannot reasonably estimate the possible loss or range of loss, if any.

Adverse developments in this litigation could result in significant costs or damages; however, based on the information currently available, management does not believe the resolution of this matter will have a material adverse effect on the Company's consolidated financial position, results of operations, or cash flows.

At December 31, 2025, there was no outstanding litigation that we believe would result in material losses if decided against us, and we do not believe that there are any unasserted matters that are reasonably possible to result in a material loss.

The interest income for the year ended December 31, 2025, December 31, 2024 and December 31, 2023, primarily relates to income on our interest rate swaps and cross currency swaps discussed in note 21.

***Credit facilities***

The following table presents availability under our revolving credit facility:

---

|:---|:---|
| *(in millions)* | **December 31, 2025** |
| Capacity | $1400.0 |
| Undrawn letters of credit outstanding | (19.5) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unused availability | $1380.5 |

---

In June 2023, we amended the revolving credit facility to increase its funding limit to $975.0 million and extended the term to June 29, 2028. We capitalized $2.3 million of fees in connection with this transaction.

In October 2025, we amended the revolving credit facility to increase its funding limit to $1,400.0 million and extended the term to October 9, 2030. We capitalized $3.8 million of fees in connection with this transaction. Refer to the "Senior secured credit facilities" section below for further discussion of this amendment.

***Receivables facility***

In October 2025, we terminated our receivables facility, which had a funding limit of $400.0 million. The cost associated with terminating this arrangement was not material.

***Senior secured credit facilities***

On December 31, 2025, the senior secured credit facilities consisted of a $1,400.0 million revolving credit facility that matures on October 9, 2030, a $645.2 million term loan facility that matures on October 9, 2032 and a $469.2 million term loan facility that matures on October 9, 2030. The revolving credit facility allows us to issue letters of credit and short-term notes. Borrowings under the facilities are guaranteed by substantially all of our domestic subsidiaries and secured by substantially all of their assets. The senior secured credit facilities bear interest at variable rates. The margin on the revolving credit facility decreases if certain net leverage ratios are achieved. Various other immaterial fees are payable under the facilities.

In October 2025, we completed a refinancing that included the issuance of €400.0 million and €550.0 million of senior secured term loans, maturing in October 2030 and October 2032, respectively. These loans bear interest at EURIBOR plus 150 basis points and EURIBOR plus 250 basis points, respectively. The proceeds from these issuances, along with cash on hand, were used to repay our outstanding U.S. dollar term loans B-6, Euro term loans B-4 and B-5, the remaining 2.625% secured notes, and the receivables facility. We capitalized $8.0 million of fees and expensed $4.4 million of fees in connection with this transaction.

In connection with the refinancing, we amended our revolving credit facility to obtain an additional $425.0 million in available funding, increasing the total availability under the facility to $1,400.0 million. The revolving credit facility will mature in October 2030.

------

Both the newly issued senior secured term loans and the amended revolving credit facility include covenants that we consider to be usual and customary. As part of the refinancing and the addition of the new €400.0 million term loan, (i) the leverage-based financial covenant in the credit facility agreement became a full-time financial maintenance covenant, whereas previously it had been a "springing covenant", and (ii) a new consolidated interest coverage ratio financial maintenance covenant was added to the credit facilities agreement, in both cases on usual and customary terms for facility agreements governing these types of senior secured term loan and revolving credit facilities. As of December 31, 2025, our net leverage and consolidated interest coverage ratio were within the covenant requirements.

We are required to make additional prepayments if: (i) we generate excess cash flows, as defined, at specified percentages that decline if certain net leverage ratios are achieved; or (ii) we receive cash proceeds from certain types of asset sales or debt issuances. No additional required prepayments have become due since the inception of the credit facilities.

We may also prepay the term loans at our option. In 2025 and 2024, we made optional prepayments of $449.4 million and $526.4 million, respectively, of Euro term loans and $80.8 million and $690.0 million, respectively, of U.S. dollar term loans. In connection with the 2025 and 2024 prepayments, we recorded losses on extinguishment of debt of $1.1 million and $10.9 million, respectively, for the proportional write-off of related unamortized deferred financing costs.

***Common stock***

Each share of common stock entitles the holder to one vote for applicable matters. Holders are entitled to receive dividends declared by the board of directors and a pro rata share of assets available for distribution after satisfaction of the rights of the preferred stockholders.

***Share purchase program***

In October 2025, our Board of Directors authorized the repurchase of up to $500.0 million of our common stock, exclusive of fees, commissions and related transaction expenses. Repurchases may be funded through our available cash, borrowings under existing credit facilities or other financing arrangements approved by the Board of Directors.

Management is authorized to repurchase our common stock on the open market or in privately negotiated transactions, through one or more Rule 10b5-1 trading plans, Rule 10b-18 repurchase programs, accelerated share repurchase programs, including any collateral arrangements, or a combination thereof. The timing, manner, price and amount of repurchases will be determined by management depending upon economic, market and other conditions. The repurchase program may be modified, suspended, or terminated at any time. Shares repurchased under the program are held as treasury stock.

During the fourth quarter of 2025, we repurchased $75.0 million of our common stock (6.6 million shares). As of December 31, 2025, $425.0 million remained available for repurchase under the program.

The reclassifications effects shown above were immaterial to the financial statements and were made to either cost of sales, SG&A expense, other (expense) income, net or interest expense depending upon the nature of the underlying transaction. The income tax effects in 2025 and 2024 on foreign currency translation were due to our net investment hedge and cross-currency swap discussed in note 21.

**17.&nbsp;&nbsp;&nbsp;&nbsp;Employee benefit plans**

We sponsor many defined benefit plans across the globe. Those plans have resulted in significant obligations to pay benefits to current and former employees, many of which are at least partially funded with plan assets. Unless required otherwise, we typically seek to close the defined benefit plans to new participants. Defined benefit plans do not materially impact our earnings, and as a result, certain disclosures have been omitted.

We approved the termination of one of our two U.S. pension plans during 2024. The pension liability was partially settled in December 2024 due to lump sum distribution payments of $54.2 million to plan participants. We recorded $9.3 million of pension termination costs for the year ended December 31, 2024, which are included in other income or expenses as discussed in note 19.

The remaining pension liability was settled in 2025, primarily through the purchase of annuity contracts totaling $97.7 million. As a result of the settlement, we recorded $16.3 million of pension termination costs in 2025, which were primarily recognized in other income or expense.

The remaining pension surplus from the plan was used by the Company, as prescribed by applicable regulations, to fund a Qualified Replacement Plan, which will primarily fund future non-elective contributions to the Avantor U.S. 401(k) defined contribution plan.

&nbsp;&nbsp;&nbsp;&nbsp;

Actuarial gains for the year ended December 31, 2025 were primarily attributable to higher discount rates (excluding the terminated U.S. plan) and increases in lump-sum conversion rates for the U.S. plans. Additional gains resulted from lower inflation assumptions. These favorable impacts were partially offset by experience losses in the non-U.S. plans during the year. For 2024, increases in discount rates in both the U.S. and U.K. generated most of the actuarial gains in the U.S. and non-U.S. pension plan obligations. These gains were partially offset by experience losses in the U.S. related to annuity purchases completed as part of the plan termination process. Non-U.S. plans also recorded experience gains in 2024 due to involuntary terminations. Actuarial losses in the U.S. postretirement medical plan in 2025 were driven primarily by unfavorable experience and a decrease in the discount rate, compared to 2024, when actuarial gains were mainly attributable to favorable experience.

1. Investments are measured at fair value using the net asset value per share practical expedient, and therefore, are not classified in the fair value hierarchy.

For periods prior to the plan's termination, the U.S. pension plan's investment strategy focused on aligning the duration of plan assets with the duration of benefit obligations. This strategy utilized diversified fixed-income funds to hedge movements in the discount rate, with investments primarily in long-duration, investment-grade corporate bonds across industrial, financial, and utility sectors. Surplus assets were invested in equity funds. The plan was fully settled and terminated in 2025, and therefore no U.S. pension plan assets remained invested as of December 31, 2025.

------

For the non-U.S. plans, in many cases we enter into insurance contracts to guarantee payment of benefits for an annual fee. Otherwise, our primary investment strategy is to seek a return on plan assets sufficient to achieve our long-term funding objectives. To seek this return, we invest significantly in global equity funds and secondarily in fixed income funds to mitigate inflation and interest rate risk. These funds primarily invest in inflation-linked and other types of government bonds. We estimate the expected long-term rate of return on plan assets in a similar manner to the U.S. plans.

The following table presents changes to plan assets of non-U.S. plans that were measured using unobservable inputs:

At December 31, 2025, unvested awards have remaining expense of $67.1 million to be recognized over a weighted average period of 1.5 years.

We recognized a reduction to income tax expense as a result of tax benefits associated with our stock-based compensation plans of $3.0 million, $5.9 million and $5.0 million, in 2025, 2024 and 2023, respectively.

Our stock-based compensation awards have been issued under a succession of plans sponsored by the ultimate parent of our business, which is currently Avantor, Inc. In connection with our IPO, we adopted the 2019 Plan. The 2019 Plan provides for up to 23.5 million shares of common stock to be issued in the form of stock options, RSUs or other equity-based awards or cash-based awards. The 2019 Plan also provides for 1% annual increases to the number of shares of common stock available for issuance unless reduced by our Board of Directors. At December 31, 2025, 43.7 million shares were available for future issuance. The 2019 Plan will automatically terminate on May 17, 2029, and no award under the plan may be granted after this date.

During 2025, we granted RSUs that vest annually over one to three years, as specified in the underlying grant agreements, subject to the recipient continuously providing service to us throughout the vesting period. Certain of those awards contain performance and market conditions that impact the number of shares that will ultimately vest. We recorded expense on such awards of $2.8 million, $9.3 million and $3.1 million, for the years ended December 31, 2025, 2024 and 2023, respectively.

The fair value of RSUs that vested in 2025, 2024 and 2023 was $32.4 million, $31.0 million and $29.5 million, respectively.

Most of the net foreign currency remeasurement (loss) gain from financing activities was caused by the volatility of the U.S. dollar on unhedged intercompany loan positions as disclosed in note 6. Other income or expense related to our defined benefit plans primarily relates to pension termination charges as described in note 17, and the expected returns on defined benefit plan assets.

***Deferred taxes***

The following table presents the components of deferred tax assets and liabilities:

---

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Deferred income tax liabilities | (557.1) | (557.3) |

---

The (decrease) increase to the valuation allowance was $(24.0) million in 2025, $8.0 million in 2024 and $26.4 million in 2023.

At December 31, 2025, $132.1 million of the valuation allowances presented above relate to foreign net operating loss carryforwards that are not expected to be realized. We evaluate the realization of deferred tax assets by considering such factors as the reversal of existing taxable temporary differences, expected profitability by tax jurisdiction and available carryforward periods. The extent and timing of any such reversals will influence the extent of tax benefits recognized in a particular year. Should applicable losses, credits and deductions ultimately be realized, the resulting reduction in the valuation allowance would generally be recognized as an income tax benefit.

***Uncertain tax positions***

We file federal income tax returns in the United States and other tax returns in various states and international jurisdictions. In the normal course of business, we are subject to examination by taxing authorities throughout the world. In these cases, we evaluate our tax position using the recognition threshold and the measurement analysis in accordance with the accounting guidance. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit recognized in our financial statements. Tax years are subject to examination in the United States since 2021 at the federal level, since 2017 for certain states and in certain international jurisdictions since 2014.

The following table reflects changes to the reserve for uncertain tax positions, excluding accrued interest and penalties:

At December 31, 2025, December 31, 2024 and December 31, 2023, the total amount of unrecognized tax benefits that, if recognized, would reduce income tax expense and the effective tax rate by $79.1 million, $31.3 million and $50.8 million, respectively.

Accrued interest and penalties related to the reserve for uncertain tax positions were $11.1 million at December 31, 2025, $7.2 million at December 31, 2024 and $8.2 million at December 31, 2023.

The development of reserves for uncertain tax positions requires judgments about tax issues, potential outcomes and the timing of settlement discussions with tax authorities. If we were to prevail on all uncertain tax positions, we would recognize an income tax benefit.

***Deferred tax treatment of retained goodwill***

The Company completed the sale of its Clinical Services business on October 17, 2024. Under ASC 350-20-40-3, the Company determined the amount of goodwill that was deconsolidated in the sale by allocating goodwill between the Clinical Services business and the Company. The goodwill that was retained from the Clinical Services business by the Company has been treated as non-deductible goodwill, which creates a permanent basis difference for tax purposes for which no deferred tax liability has been provided.

***Deferred tax treatment of goodwill impairment***

In the third quarter of 2025, the Company recorded a goodwill impairment charge of $785.0 million related to our Distribution reporting unit, formerly referred to as our Buy Sell reporting unit. The impairment charge was recorded against "Component 2 goodwill", which relates to book goodwill exceeding the amount that is tax-deductible resulting in the goodwill being non-deductible as a permanent difference.

***Other matters***

Undistributed earnings of foreign subsidiaries that are deemed to be permanently reinvested amount to $2,776.2 million at December 31, 2025. In addition to the one-time transition tax imposed on all accumulated foreign undistributed earnings through December 31, 2017, undistributed earnings of foreign subsidiaries as of December 31, 2025 may still be subject to certain taxes upon repatriation, primarily

------

where foreign withholding taxes apply. We assert indefinite reinvestment related to investments in foreign subsidiaries. It is not practicable to calculate the unrecognized deferred tax liability on undistributed foreign earnings due to the complexity of the hypothetical calculation.

At December 31, 2025, we had federal net operating loss carryforwards of $3.1 million that have indefinite expirations and state net operating loss carryforwards of $70.8 million that expire at various times through 2041. In addition, we had foreign net operating loss carryforwards of $560.5 million, which predominantly have indefinite expirations.

On July 4, 2025, the U.S. enacted H.R. 1, commonly referred to as the One Big Beautiful Bill Act ("Act"). As a result of the Act, our current cash tax obligations were reduced by approximately $43.0 million due to changes to several provisions, including the reinstatement of immediate expensing for domestic research and development expenditures, the extension of 100% bonus depreciation for qualified properties and the relaxation of limitations on the deductibility of business interest expense. The impact on income tax expense resulting from the Act was immaterial.

**21.&nbsp;&nbsp;&nbsp;&nbsp;Derivative and hedging activities** 

***Hedging instruments:***

We engage in hedging activities to reduce our exposure to foreign currency exchange rates and interest rates. Our hedging activities are designed to manage specific risks according to our strategies, as summarized below, which may change from time to time. Our hedging activities consist of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Economic hedges —* We are exposed to changes in foreign currency exchange rates on certain of our euro-denominated term loans and notes that move inversely from our portfolio of euro-denominated intercompany loans. The currency effects for these non-derivative instruments are recorded through earnings in the period of change and substantially offset one another;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Other hedging activities —* Certain of our subsidiaries hedge short-term foreign currency denominated business transactions, external debt and intercompany financing transactions using foreign currency forward contracts. These activities were not material to our consolidated financial statements.

***Cash flow hedges of interest rate risk***

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company's variable-rate debt. During the next twelve months, the Company estimates that an immaterial amount will be reclassified as an increase to interest expense.

------

In April of 2023, we executed an interest rate swap with a notional amount of $100.0 million to convert SOFR based floating rate interest to fixed rate interest. The swap was designated as a cash flow hedge and was intended to mitigate exposure to fluctuations in interest rates.

During the quarter ended December 31, 2025, the hedging relationship for the $100.0 million interest rate swap became ineffective because the forecasted transaction was deemed no longer probable of occurring. As a result, hedge accounting was discontinued, and an immaterial gain was reclassified from AOCI into earnings. Following the discontinuation of hedge accounting, we terminated the interest rate swap and received an immaterial amount of cash proceeds in October 2025.

During the quarter ended September 30, 2024, the hedging relationship for our existing $750.0 million interest rate swap became ineffective because the forecasted transaction was deemed no longer probable of occurring. As a result, hedge accounting was discontinued, and a $6.2 million gain was reclassified from AOCI into earnings. Following the discontinuation of hedge accounting, we terminated the interest rate swap and received $6.2 million of cash proceeds in October 2024.

As of December 31, 2025, we had no outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk.

***Net investment hedges***

We are exposed to foreign currency exchange rate fluctuations on the investments we hold in foreign entities, specifically related to the risk of changes in the EUR-USD exchange rates affecting our net investment in EUR-functional-currency consolidated subsidiaries.

For derivatives designated as net investment hedges, gains and losses are recorded in AOCI as part of the cumulative translation adjustment. These amounts are reclassified from AOCI into earnings only when the hedged net investment is sold or substantially liquidated.

As of December 31, 2025, we had the following outstanding foreign currency derivatives that were used to hedge our net investments in foreign operations:

| **Foreign currency derivative** | **Number of instruments** | **Notional sold** | **Notional sold** | **Notional purchased** |
| Cross-currency swaps | 3 | € | 732.1 | $750.0 |

---

As of December 31, 2024, we held a cross-currency swap with a notional amount of $750.0 million, which was scheduled to mature in April 2025. In April 2025, prior to maturity, we executed a transaction to amend and extend the original swap. The liability position of the original cross-currency swap was blended and rolled into three separate cross-currency swap agreements, each with a notional amount of $250.0 million, maturing in April 2027, April 2028, and April 2029, respectively.

Our cross-currency swaps involve the receipt of functional-currency fixed-rate amounts from a counterparty in exchange for making foreign-currency fixed-rate payments over the life of the agreement.

***Non-derivative financial instruments which are designated as hedging instruments:***

We designated all of our outstanding €400.0 million 3.875% senior unsecured notes, issued on July 17, 2020, and maturing on July 15, 2028, as a hedge of our net investment in certain of our European operations. In October 2024, we de-designated these notes as a net investment hedge. The de-designation had no impact on earnings because accumulated gains or losses on a net investment hedge are only reclassified into earnings upon a liquidation event or deconsolidation of the hedged foreign subsidiary.

In November 2025, we designated €144.0 million of our outstanding €400.0 million 3.875% senior unsecured notes as a hedge of our net investment in certain European operations.

For instruments that are designated and qualify as net investment hedges, remeasurement gains or losses on the foreign-currency denominated debt are recorded as a component of AOCI. Net investment hedge effectiveness is assessed based on changes in the spot rate of the foreign currency denominated debt. The critical terms of the foreign currency notes match the portion of the net investments designated as being hedged. For all periods presented, the net investment hedge was equal to the designated portion of our European operations and was considered perfectly effective.

The accumulated gain related to the foreign currency denominated debt designated as a net investment hedge, classified within the foreign currency translation adjustment component of AOCI, was $3.0 million and $6.0 million as of December 31, 2025 and December 31, 2024, respectively.

The amount of loss related to the foreign currency denominated debt designated as a net investment hedge, classified within the foreign currency translation adjustment component of other comprehensive income or loss, is presented below:

**22.&nbsp;&nbsp;&nbsp;&nbsp;Financial instruments and fair value measurements**

Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable and debt.

Certain financial and non-financial assets and liabilities are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.

As discussed in note 10 and 11, during the second quarter of 2023, property, plant and equipment, customer relationships and developed technology related to Ritter were deemed to be impaired and their carrying values were reduced to estimated fair values of $25.9 million, $31.4 million and $19.3 million, respectively. This was the result of an impairment charge of $160.8 million. We estimated the fair value of these assets using Level 3 inputs, which included a discounted cash flow analysis.

As discussed in note 11, during the third quarter of 2025, goodwill associated with our Distribution reporting unit was determined to be impaired. As a result, the carrying amount was reduced to its estimated fair value of $3,500.0 million, resulting in an impairment charge of $785.0 million. We estimated the fair value of the Distribution reporting unit using Level 3 inputs under the fair value hierarchy, which included a discounted cash flow analysis and a guideline public company method.

***Assets and liabilities for which fair value is only disclosed***

The carrying amount of cash and cash equivalents was the same as its fair value and is a Level 1 measurement. The carrying amounts for trade accounts receivable and accounts payable approximated fair value due to their short-term nature and are Level 2 measurements.

**24.&nbsp;&nbsp;&nbsp;&nbsp;Subsequent Events**

In February 2026, the Company announced its intention to implement a new operating model and reporting segment structure effective January 1, 2026. Under the new structure, the Company will report its financial results through two segments: VWR Distribution & Services and Bioscience & Medtech Products. This realignment reflects the Company's updated management structure and the manner in which the CODM will assess performance and allocate resources beginning in 2026.

These changes to the reporting segment structure do not affect the Company's consolidated financial statements for the year ended December 31, 2025. Comparative prior-period segment information will be recast in future filings to conform to the new segment presentation.

**25.&nbsp;&nbsp;&nbsp;&nbsp;Condensed unconsolidated financial information of Avantor, Inc.**

Pursuant to SEC regulations, the following presents condensed unconsolidated financial information of the registrant, Avantor, Inc.

The following condensed unconsolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto because certain applicable disclosures are provided there. In these condensed unconsolidated financial statements, all of our subsidiaries are wholly-owned for the periods presented and presented as investments of Avantor, Inc. under the equity method. Under that method, the equity interest in subsidiaries' assets and liabilities is stated as a net non current asset at historical cost on the balance sheet.

(b) [In the event of a Change in Control, provided that the Participant has not undergone a Termination prior to occurrence thereof, any unvested Options will become vested as of immediately prior to such Change in Control.] [Notwithstanding the foregoing, in the event of a Change in Control, any unvested Options that are assumed by the acquiror in the Change in Control will remain outstanding and subject to vesting; provided, however, that in the event the Participant's employment terminates within [ ] years following a Change in Control due to either (i) a termination by the Company without Cause or (ii) a resignation by the Participant with Good Reason, any unvested Options will immediately vest as of the date of termination. If the Options are not assumed by the acquiror in the Change in Control, all unvested Options will become vested in full upon the consummation of the Change in Control.] (c) [For purposes of Section 2(b), "Good Reason" means: (i) a material diminution to the Participant's base salary, bonus opportunity, authority, duties or responsibilities, (ii) the Company fails to make any compensatory payment to the Participant when due, which is required to be paid to the Participant pursuant to this Agreement or any other material agreement between the Participant and the Company, (iii) a relocation of the Participant's principal place of employment to a location that is outside a 50 mile radius from the Participant's principal place of employment immediately prior to the Change in Control, or (iv) any other action or inaction by the Company which constitutes a material breach of this

&nbsp;&nbsp;&nbsp;&nbsp;2 Agreement or any other material agreement with the Company; provided that, in order for the Participant's resignation for Good Reason to be effective, written notice of the occurrence of any event that constitutes Good Reason must be delivered by the Participant to the Company within 90 days after the Participant has actual knowledge of the occurrence of any such event and the occurrence of such event.] (d) [Notwithstanding any of the foregoing to the contrary, in the event of the Participant's Termination due to death or Disability, any Options that are unvested as of the date of Termination due to death or Disability shall vest in full and remain outstanding for [ ] year thereafter (but in no event beyond the Option Period Expiration Date).] (e) [Notwithstanding any of the foregoing, in the event of the Participant's Termination due to Retirement, any Options that are unvested as of the date of Termination due to Retirement (such date, the "Retirement Date") will be treated as follows. (i) If the Retirement Date occurs prior the [ ] anniversary of the Grant Date, any unvested Options shall immediately forfeit as of the Retirement Date. (ii) If the Retirement Date occurs on or following the [ ] anniversary of the Grant Date but prior to the [ ] anniversary of the Grant Date, the Options shall continue to vest, and Participant shall be entitled to receive a pro rata portion of the number of unvested Options that otherwise would have vested in accordance with Section 2(a) had the Participant been employed as of the applicable vesting date (such amount, the "Pro Rata Amount"). The Pro Rata Amount shall equal: the number of Options that otherwise would have vested on the next vesting date following the date of the Participant's Termination due to Retirement had the Participant been employed on such vesting date, multiplied by a fraction, (A) the numerator of which is the number of completed months from the most recent vesting date through the last completed month prior to the Retirement Date, and (B) the denominator of which is 12.] (f) [Notwithstanding any of the foregoing, in the event of the Participant's Termination due to Retirement on or following the [ ] anniversary of the Grant Date, any vested Options (including Options that vest pursuant to Section 2(e)) shall remain exercisable for [ ] years after the applicable vesting date (but in no event beyond the Option Period Expiration Date).] (g) [For purposes of Sections 2(e) and 2(f), "Retirement" means, with respect to the Participant, such Participant's voluntary Termination on or after of the date on which (i) such Participant's age plus years of continuous service with the Company or one of its Subsidiaries equals at least 65 and (ii) the Participant is at least age 55 and has completed at least five years of continuous service with the Company or one of its Subsidiaries.] 3. Exercise of Options Following Termination. [In addition to the terms set forth in Sections 2(d) and 2(e),] the provisions of Section 7(c)(ii) of the Plan are incorporated herein by reference and made a part hereof.

&nbsp;&nbsp;&nbsp;&nbsp;3 4. Method of Exercising Options. The Options may be exercised by the delivery of notice of the number of Options that are being exercised accompanied by payment in full of the Exercise Price applicable to the Options so exercised. Such notice shall be delivered either (a) in writing to the Company at its principal office or at such other address as may be established by the Committee, to the attention of the Company's General Counsel or (b) to a third-party plan administrator as may be arranged for by the Company or the Committee from time to time for purposes of the administration of outstanding Options under the Plan, in the case of either (a) or (b), as communicated to the Participant by the Company from time to time. Payment of the aggregate Exercise Price may be made using any of the methods described in Section 7(d)(i) or (ii) of the Plan; provided, that the Participant may not use the methods described in Section 7(d)(ii)(A) or (C) of the Plan unless specifically authorized by the Committee. 5. Issuance of Shares of Common Stock. Following the exercise of an Option hereunder, as promptly as practical after receipt of such notification and full payment of such Exercise Price and any required income or other tax withholding amount (as provided in Section 14 hereof), the Company shall issue or transfer, or cause such issue or transfer, to the Participant the number of shares of Common Stock with respect to which the Options have been so exercised, and shall either (a) deliver, or cause to be delivered, to the Participant a certificate or certificates therefor, registered in the Participant's name or (b) cause such shares of Common Stock to be credited to the Participant's account at the third-party stock plan administrator. 6. Company; Participant. (a) The term "Company" as used in this Option Agreement (including any Exhibit attached hereto) with reference to employment shall include the Company and its Subsidiaries. (b) Whenever the word "Participant" is used in any provision of this Option Agreement under circumstances where the provision should logically be construed to apply to the executors, the administrators, or the person or persons to whom the Options may be transferred by will or by the laws of descent and distribution, the word "Participant" shall be deemed to include such person or persons. 7. Non-Transferability. The Options are not transferable by the Participant except to Permitted Transferees in accordance with Section 13(b) of the Plan. Except as otherwise provided herein, no assignment or transfer of the Options, or of the rights represented thereby, whether voluntary or involuntary, by operation of law or otherwise, shall vest in the assignee or transferee any interest or right herein whatsoever, but immediately upon such assignment or transfer the Options shall terminate and become of no further effect. 8. Rights as Shareholder. The Participant or a Permitted Transferee of the Options shall have no rights as a shareholder with respect to any share of Common Stock covered by an Option until the Participant (or such Permitted Transferee, as applicable) shall have become the holder of record or the beneficial owner of such share of Common Stock, and no adjustment shall be made for dividends or distributions or other rights in respect of such Share of Common Stock for which the record date is prior to the date upon which the Participant (or a Permitted Transferee, as applicable) shall become the holder of record or the beneficial owner thereof.

Notwithstanding the above, all notices and communications between the Participant and any third-party plan administrator shall be mailed, delivered, transmitted or sent in accordance with the procedures established by such third-party plan administrator and communicated to the Participant from time to time. 11.

This Option Agreement does not confer upon the Participant any right to continue as an employee or service provider to the Company. 12. Binding Effect. This Option Agreement shall be binding upon the heirs, executors, administrators and successors of the parties hereto. 13. Waiver and Amendments. Except as otherwise set forth in Section 12 of the Plan, any waiver, alteration, amendment or modification of any of the terms of this Option Agreement shall be valid only if made in writing and signed by the parties hereto; provided, however, that any such waiver, alteration, amendment or modification is consented to on the Company's behalf by the Committee. No waiver by either of the parties hereto of their rights hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver specifically states that it is to be construed as a continuing waiver. 14. Clawback / Forfeiture. Notwithstanding anything to the contrary contained herein or in the Plan, if the Participant has engaged in or engages in any Detrimental Activity, then the Committee may, in its sole discretion, take actions permitted under the Plan, including: (i) canceling the Options; or (ii) requiring that the Participant forfeit any gain realized on the exercise of the Options or the disposition of any shares of Common Stock received upon exercise of the Options, and repay such gain to the Company. In addition, if the Participant receives any amount in excess of what the Participant should have received under the terms of this Option Agreement for any reason (including without limitation by reason of a financial restatement, mistake in calculations or other administrative error), then the Participant shall be required to repay any such excess amount to the Company. [Without limiting the foregoing, all Options shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with applicable law] [Without limiting the foregoing, all Options shall be subject to any clawback or similar policy as permitted or mandated by applicable laws, rules, regulations or any

![](form2026optiongrantnotic007.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;5 Company policy as enacted, adopted or modified from time to time, including any recoupment policy adopted by the Company and, to the extent applicable, the Erroneously Awarded Compensation Recovery Policy (as may be amended from time to time) or any other Dodd-Frank clawback policy adopted by the Company]. 15. Governing Law and Venue. This Option Agreement shall be construed and interpreted in accordance with the laws of the State of Delaware, without regard to the principles of conflicts of law thereof. Notwithstanding anything contained in this Option Agreement, the Grant Notice or the Plan to the contrary, if any suit or claim is instituted by the Participant or the Company relating to this Option Agreement, the Grant Notice or the Plan, the Participant hereby submits to the exclusive jurisdiction of and venue in the courts of Delaware[, unless Participant has an agreement with the Company to arbitrate employment-related disputes, in which case any disputes relating to this Option Agreement, the Grant Notice, or the Plan will be resolved through arbitration]. 16. Plan. The terms and provisions of the Plan are incorporated herein by reference. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this Option Agreement (including the Grant Notice), the Plan shall govern and control. 17.

Participant acknowledges and agrees that this Grant is expressly conditioned on Participant's acceptance of the terms and conditions of the Restrictive Covenant Agreement. Participant further acknowledges and agrees that by accepting this Grant, Participant is accepting and agreeing to all of the terms and conditions of the Restrictive Covenant Agreement, which includes, among other things and to the extent permissible under applicable law, non-competition, customer and employee non-solicitation, and non-disclosure provisions. (b) Consequences of Breach. Any breach of the Restrictive Covenant Agreement will constitute Detrimental Activity under the Plan. In the event of such breach, Participant shall immediately forfeit all unvested Options without payment[, which shall include, for the avoidance of doubt, unvested Options subject to continued vesting under Section 2(e)]. For any Options that have vested during the 12 month period prior to the breach and after such breach, Participant shall repay or otherwise reimburse the Company, immediately upon demand, an amount in cash or Avantor, Inc., common stock equal to (i) the number of shares acquired by exercising such Options multiplied by the difference between the Fair Market Value and the Exercise Price on the date the Options were exercised and (ii) any dividends paid on those shares. Participant understands and agrees that the relief provided in this Section 17(b) does not constitute the Company's exclusive remedy for violations of this Section 17 or the Restrictive Covenant Agreement because they do not address the irreparable harm the Company will suffer from such violations. Therefore, the Company may seek any additional legal or

------

![](form2026optiongrantnotic008.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;6 equitable remedy, including injunctive relief, for such violations.] [For Non-US Participants The Participant acknowledges and agrees that the Participant is, or, unless otherwise determined by the Company, will become, party to an agreement with the Company which contains restrictive covenant obligations with respect to the Participant [(any such agreement(s), a "Restrictive Covenant Agreement")]. The Participant hereby acknowledges and reaffirms the Participant's obligations under any such Restrictive Covenant Agreement and hereby acknowledges and agrees that any breach of a Restrictive Covenant Agreement will constitute Detrimental Activity under the Plan.] 18. Exhibit for Non-US Participants. If the Participant is residing and/or working outside of the United States, the Option shall be subject to any special provisions set forth in Exhibit A to this Option Agreement. If the Participant becomes based outside the United States during the life of the Option, the special provisions set forth in Exhibit A shall apply to the Participant to the extent that the Company determines that the applications of such provisions is necessary or advisable for legal or administrative reasons. Moreover, if the Participant relocates between any of the countries included on Exhibit A, the special provisions set forth in Exhibit A for such country shall apply to the Participant to the extent that the Company determines that the applications of such provisions is necessary or advisable for legal or administrative reasons. Exhibit A constitutes part of this Option Agreement. 19. Data Privacy Acknowledgment. By electing to participate in the Plan via the Company's acceptance procedures, the Participant is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Personal Data (as defined below) by the Company and the transfer of Personal Data to the recipients mentioned herein, including recipients located in countries which do not adduce an adequate level of protection from a European (or other) data protection law perspective, for the purposes described herein. (a) Declaration of Consent. The Participant understands that he or she needs to review the following information about the processing of his or her personal data by or on behalf of the Company, the Participant's employer or contracting party (the "Employer") and/or any Subsidiary as described in this Option Agreement and any other Plan materials (the "Personal Data") and declare his or her consent. About the processing of the Participant's Personal Data in connection with the Plan and this Option Agreement, the Participant understands that the Company is the controller of his or her Personal Data. (b) Data Processing and Legal Basis. The Company collects, uses and otherwise processes Personal Data about the Participant for the purposes of allocating shares of Common Stock and implementing, administering and managing the Plan. The Participant understands that this Personal Data may include, without limitation, his or her name, home address and telephone number, email address, date of birth, social insurance number, passport number or other identification number (e.g., resident registration number), salary, nationality, job title, any shares of stock or directorships held in the Company, details of all Options or any other entitlement to shares of stock or equivalent benefits awarded, cancelled, exercised, vested,

------

![](form2026optiongrantnotic009.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;7 unvested or outstanding in the Participant's favor. The legal basis for the processing of the Participant's Personal Data, where required, will be his or her consent. (c) Stock Plan Administration Service Providers. The Participant understands that the Company may transfer his or her Personal Data, or parts thereof, to a third-party stock plan administrator (and its affiliated companies, as applicable) based in the United States which will assist the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Participant's Personal Data with such different service provider that serves the Company in a similar manner. The Participant understands and acknowledges that the Company's service provider will open an account for him or her to receive and trade shares of Common Stock acquired under the Plan and that he or she will be asked to agree on separate terms and data processing practices with the service provider, which is a condition of the Participant's ability to participate in the Plan. (d) International Data Transfers. The Participant understands that the Company and, as of the date hereof, any third parties assisting in the implementation, administration and management of the Plan, such as a third-party stock plan administrator, are based in the United States. The Participant understands and acknowledges that his or her country may have enacted data privacy laws that are different from the laws of the United States. For example, the European Commission has issued only a limited adequacy finding with respect to the United States that applies solely if and to the extent that companies self-certify and remain self-certified under the EU/U.S. Privacy Shield program. The Company currently participates in the EU/U.S. Privacy Shield Program. The Company's legal basis for the transfer of the Participant's Personal Data is his or her consent. (e) Data Retention. The Participant understands that the Company will use his or her Personal Data only as long as is necessary to implement, administer and manage his or her participation in the Plan, or to comply with legal or regulatory obligations, including under tax and securities laws. In the latter case, the Participant understands and acknowledges that the Company's legal basis for the processing of his or her Personal Data would be compliance with the relevant laws or regulations. When the Company no longer needs the Participant's Personal Data for any of the above purposes, the Participant understands the Company will remove it from its systems. (f) Voluntariness and Consequences of Denial / Withdrawal of Consent. The Participant understands that his or her participation in the Plan and his or her consent is purely voluntary. The Participant may deny or later withdraw his or her consent at any time, with future effect and for any or no reason. If the Participant denies or later withdraws his or her consent, the Company can no longer offer the Participant participation in the Plan or offer other equity awards to the Participant or administer or maintain such awards and the Participant would no longer be able to participate in the Plan. The Participant further understands that denial or withdrawal of his or her consent would not affect his or her status or salary as an employee or his or her career and that the Participant would merely forfeit the opportunities associated with the Plan. (g) Data Subject Rights. The Participant understands that data subject rights regarding the processing of Personal Data vary depending on the applicable law and that,

------

![](form2026optiongrantnotic010.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;8 depending on where the Participant is based and subject to the conditions set out in the applicable law, the Participant may have, without limitation, the rights to (i) inquire whether and what kind of Personal Data the Company holds about him or her and how it is processed, and to access or request copies of such Personal Data, (ii) request the correction or supplementation of Personal Data about him or her that is inaccurate, incomplete or out-of-date in light of the purposes underlying the processing, (iii) obtain the erasure of Personal Data no longer necessary for the purposes underlying the processing, processed based on withdrawn consent, processed for legitimate interests that, in the context of his or her objection, do not prove to be compelling, or processed in non-compliance with applicable legal requirements, (iv) request the Company to restrict the processing of his or her Personal Data in certain situations where the Participant feels its processing is inappropriate, (v) object, in certain circumstances, to the processing of Personal Data for legitimate interests, and to (vi) request portability of the Participant's Personal Data that he or she has actively or passively provided to the Company (which does not include data derived or inferred from the collected data), where the processing of such Personal Data is based on consent or his or her employment and is carried out by automated means. In case of concerns, the Participant understands that he or she may also have the right to lodge a complaint with the competent local data protection authority. Further, to receive clarification of, or to exercise any of, the Participant's rights, the Participant understands that he or she should contact his or her local human resources representative. (h) Alternate Basis and Additional Consents. Finally, the Participant understands that the Company may rely on a different basis for the collection, processing or transfer of Personal Data in the future and/or request that the Participant provide another data privacy consent. If applicable, the Participant agrees that upon request of the Company or the Employer, the Participant will provide an executed acknowledgment or data privacy consent form (or any other agreements or consents) that the Company and/or the Employer may deem necessary to obtain from him or her for the purpose of administering his or her participation in the Plan in compliance with the data privacy laws in his or her country, either now or in the future. The Participant understands and agrees that he or she will not be able to participate in the Plan if the Participant fails to provide any such consent or agreement requested by the Company and/or the Employer. 20. Acquired Rights. The Participant acknowledges and agrees that: (a) the Company may terminate or amend the Plan at any time; (b) the award of the Option made under this Agreement is completely independent of any other award or grant and is made at the sole discretion of the Company; (c) no past grants or awards (including, without limitation, the Option awarded hereunder) give the Participant any right to any grants or awards in the future whatsoever; and (d) any benefits granted under this Agreement are not part of the Participant's ordinary salary, and shall not be considered as part of such salary in the event of severance, redundancy or resignation. 21. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;9 22. Entire Agreement. This Option Agreement [(including, without limitation, any Exhibit attached hereto)], the Grant Notice and the Plan constitute the entire agreement of the parties hereto in respect of the subject matter contained therein and supersede all prior agreements and understandings of the parties, oral and written, with respect to such subject matter. [However, unless otherwise stated therein, the Restrictive Covenant Agreement will not be considered to supersede any prior non-competition, non- solicitation, or non-disclosure agreement between Participant and the Company, which will remain in effect, and be read in conjunction with the Restrictive Covenant Agreement and any future agreements on the same subject matter, so as to afford the Company the broadest protections allowed under applicable law.] \* \* \*

Non-Transferability. The Performance Stock Units are not transferable by the Participant and no assignment or transfer of the Performance Stock Units, or of the rights represented thereby, whether voluntary or involuntary, by operation of law or otherwise, shall vest in the assignee or transferee any interest or right herein whatsoever, but immediately upon such assignment or transfer the Performance Stock Units shall terminate and become of no further effect. 7.

The Participant shall have no rights as a shareholder with respect to any share of Common Stock underlying a Performance Stock Unit unless and until the Participant shall have become the holder of record or the beneficial owner of such share of Common Stock, and no adjustment shall be made for dividends or distributions or other rights in respect of such share of Common Stock for which the record date is prior to the date upon which the Participant shall become the holder of record or the beneficial owner thereof. The Performance Stock Units shall be entitled to be credited with dividend equivalent payments upon the payment by the Company of dividends on shares of Common Stock. Such dividend equivalents will be provided in shares of Common Stock having a Fair Market Value on the date that the Performance Stock Units are settled equal to the amount of such applicable dividends, and shall be payable at the same time as the Performance Stock Units are settled in accordance with Section 3 above. In the event that any Performance Stock Unit is forfeited by its terms, the Participant shall have no right to dividend equivalent payments in respect of such forfeited Performance Stock Units. 8. Tax Withholding. The provisions of Section 13(d) of the Plan are incorporated herein by reference and made a part hereof. 9. Section 409A.

No waiver by either of the parties hereto of their rights hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver specifically states that it is to be construed as a continuing waiver. 14. Clawback / Forfeiture. Notwithstanding anything to the contrary contained herein or in the Plan, if the Participant has engaged in or engages in any Detrimental Activity, then the Committee may, in its sole discretion, take actions permitted under the Plan, including: (i) canceling the Performance Stock Units; or (ii) requiring that the Participant forfeit any gain realized on the settlement of the Performance Stock Unit or the disposition of any shares of Common Stock received upon settlement of the Performance Stock Units, and repay such gain to the Company. In addition, if the Participant receives any amount in excess of what the Participant should have received under the terms of this Performance Stock Unit Agreement for any reason (including without limitation by reason of a financial restatement, mistake in calculations or other administrative error), then the Participant shall be required to repay any such excess amount to the Company. [Without limiting the foregoing, all Performance Stock Units shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with applicable law] [Without limiting the foregoing, all Performance Stock Units shall be subject to any clawback or similar policy as permitted or mandated by applicable laws, rules, regulations or any Company policy as enacted, adopted or modified from time to time, including any recoupment policy adopted by the Company and, to the extent applicable, the Erroneously Awarded Compensation Recovery Policy (as may be amended from time to time) or any other Dodd-Frank clawback policy adopted by the Company]. 15.

&nbsp;&nbsp;&nbsp;&nbsp;8 Performance Stock Unit Agreement, the Grant Notice, or the Plan will be resolved through arbitration]. 16. Plan. The terms and provisions of the Plan are incorporated herein by reference. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this Performance Stock Unit Agreement (including the Grant Notice), the Plan shall govern and control. 17. Restrictive Covenants. [For US Participants (a) Consideration and Acceptance. Participant acknowledges and agrees that this Grant is expressly conditioned on Participant's acceptance of the terms and conditions of the Restrictive Covenant Agreement. Participant further acknowledges and agrees that by accepting this Grant, Participant is accepting and agreeing to all of the terms and conditions of the Restrictive Covenant Agreement, which includes, among other things and to the extent permissible under applicable law, non-competition, customer and employee non-solicitation, and non-disclosure provisions. (b) Consequences of Breach. Any breach of the Restrictive Covenant Agreement will constitute Detrimental Activity under the Plan. In the event of such breach, Participant shall immediately forfeit all unvested Performance Stock Units without payment[, which shall include, for the avoidance of doubt, unvested Performance Stock Units subject to continued vesting under Section 2(f)]. For any Performance Stock Units that have vested during the 12 month period prior to the breach and after such breach, Participant shall repay or otherwise reimburse the Company, immediately upon demand, an amount in cash or Avantor, Inc., common stock equal to (i) the aggregate Fair Market Value of the shares of [Common] Stock underlying such Performance Stock Units on the date the Performance Stock Units became vested and (ii) any dividends paid on those shares. Participant understands and agrees that the relief provided in this Section 17(b) does not constitute the Company's exclusive remedy for violations of this Section 17 or the Restrictive Covenant Agreement because they do not address the irreparable harm the Company will suffer from such violations. Therefore, the Company may seek any additional legal or equitable remedy, including injunctive relief, for such violations.] [For Non-US Participants The Participant acknowledges and agrees that the Participant is, or, unless otherwise determined by the Company, will become, party to an agreement with the Company which contains restrictive covenant obligations with respect to the Participant [(any such agreement(s), a "Restrictive Covenant Agreement")]. The Participant hereby acknowledges and reaffirms the Participant's obligations under any such restrictive covenant agreement and hereby acknowledges and agrees that any breach of a restrictive covenant agreement will constitute Detrimental Activity under the Plan.] 18. Exhibit for Non-US Participants. If the Participant is residing and/or working outside of the United States, the Performance Stock Units shall be subject to any special provisions

![](form2026psugrantnotice009.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;9 set forth in Exhibit B to this Performance Stock Unit Agreement. If the Participant becomes based outside the United States during the life of the Performance Stock Units, the special provisions set forth in Exhibit B shall apply to the Participant to the extent that the Company determines that the applications of such provisions is necessary or advisable for legal or administrative reasons. Moreover, if the Participant relocates between any of the countries included on Exhibit B, the special provisions set forth in Exhibit B for such country shall apply to the Participant to the extent that the Company determines that the applications of such provisions is necessary or advisable for legal or administrative reasons. Exhibit B constitutes part of this Performance Stock Unit Agreement. 19. Data Privacy Acknowledgment. By electing to participate in the Plan via the Company's acceptance procedures, the Participant is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Personal Data (as defined below) by the Company and the transfer of Personal Data to the recipients mentioned herein, including recipients located in countries which do not adduce an adequate level of protection from a European (or other) data protection law perspective, for the purposes described herein. (a) Declaration of Consent. The Participant understands that he or she needs to review the following information about the processing of his or her personal data by or on behalf of the Company, the Participant's employer or contracting party (the "Employer") and/or any Subsidiary as described in this Performance Stock Unit Agreement and any other Plan materials (the "Personal Data") and declare his or her consent. About the processing of the Participant's Personal Data in connection with the Plan and this Performance Stock Unit Agreement, the Participant understands that the Company is the controller of his or her Personal Data. (b) Data Processing and Legal Basis. The Company collects, uses and otherwise processes Personal Data about the Participant for the purposes of allocating shares of Common Stock and implementing, administering and managing the Plan. The Participant understands that this Personal Data may include, without limitation, his or her name, home address and telephone number, email address, date of birth, social insurance number, passport number or other identification number (e.g., resident registration number), salary, nationality, job title, any shares of stock or directorships held in the Company, details of all Performance Stock Units or any other entitlement to shares of stock or equivalent benefits awarded, cancelled, exercised, vested, unvested or outstanding in the Participant's favor. The legal basis for the processing of the Participant's Personal Data, where required, will be his or her consent. (c) Stock Plan Administration Service Providers. The Participant understands that the Company may transfer his or her Personal Data, or parts thereof, to a third- party stock plan administrator (and its affiliated companies, as applicable) based in the United States which will assist the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Participant's Personal Data with such different service provider that serves the Company in a similar manner. The Participant understands and acknowledges that the Company's service provider will open an account for him or her to receive and trade shares of Common Stock acquired under the Plan and that he or she will be asked to agree on separate terms and data processing practices with the service provider, which is a condition of the Participant's ability to participate in the Plan.

------

![](form2026psugrantnotice010.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;10 (d) International Data Transfers. The Participant understands that the Company and, as of the date hereof, any third parties assisting in the implementation, administration and management of the Plan, such as a third-party stock plan administrator, are based in the United States. The Participant understands and acknowledges that his or her country may have enacted data privacy laws that are different from the laws of the United States. For example, the European Commission has issued only a limited adequacy finding with respect to the United States that applies solely if and to the extent that companies self-certify and remain self- certified under the EU/U.S. Privacy Shield program. The Company currently participates in the EU/U.S. Privacy Shield Program. The Company's legal basis for the transfer of the Participant's Personal Data is his or her consent. (e) Data Retention. The Participant understands that the Company will use his or her Personal Data only as long as is necessary to implement, administer and manage his or her participation in the Plan, or to comply with legal or regulatory obligations, including under tax and securities laws. In the latter case, the Participant understands and acknowledges that the Company's legal basis for the processing of his or her Personal Data would be compliance with the relevant laws or regulations. When the Company no longer needs the Participant's Personal Data for any of the above purposes, the Participant understands the Company will remove it from its systems. (f) Voluntariness and Consequences of Denial/Withdrawal of Consent. The Participant understands that his or her participation in the Plan and his or her consent is purely voluntary. The Participant may deny or later withdraw his or her consent at any time, with future effect and for any or no reason. If the Participant denies or later withdraws his or her consent, the Company can no longer offer the Participant participation in the Plan or offer other equity awards to the Participant or administer or maintain such awards and the Participant would no longer be able to participate in the Plan. The Participant further understands that denial or withdrawal of his or her consent would not affect his or her status or salary as an employee or his or her career and that the Participant would merely forfeit the opportunities associated with the Plan. (g) Data Subject Rights. The Participant understands that data subject rights regarding the processing of Personal Data vary depending on the applicable law and that, depending on where the Participant is based and subject to the conditions set out in the applicable law, the Participant may have, without limitation, the rights to (i) inquire whether and what kind of Personal Data the Company holds about him or her and how it is processed, and to access or request copies of such Personal Data, (ii) request the correction or supplementation of Personal Data about him or her that is inaccurate, incomplete or out-of-date in light of the purposes underlying the processing, (iii) obtain the erasure of Personal Data no longer necessary for the purposes underlying the processing, processed based on withdrawn consent, processed for legitimate interests that, in the context of his or her objection, do not prove to be compelling, or processed in non-compliance with applicable legal requirements, (iv) request the Company to restrict the processing of his or her Personal Data in certain situations where the Participant feels its processing is inappropriate, (v) object, in certain circumstances, to the processing of Personal Data for legitimate interests, and to (vi) request portability of the Participant's Personal Data that he or she has actively or passively provided to the Company (which does not include data derived or inferred from the collected data), where the processing of such Personal Data is based on consent or his or her employment and is carried out by automated means. In case of concerns, the Participant understands that he or she may also have the right to lodge a complaint with the

------

![](form2026psugrantnotice011.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;11 competent local data protection authority. Further, to receive clarification of, or to exercise any of, the Participant's rights, the Participant understands that he or she should contact his or her local human resources representative. (h) Alternate Basis and Additional Consents. Finally, the Participant understands that the Company may rely on a different basis for the collection, processing or transfer of Personal Data in the future and/or request that the Participant provide another data privacy consent. If applicable, the Participant agrees that upon request of the Company or the Employer, the Participant will provide an executed acknowledgment or data privacy consent form (or any other agreements or consents) that the Company and/or the Employer may deem necessary to obtain from him or her for the purpose of administering his or her participation in the Plan in compliance with the data privacy laws in his or her country, either now or in the future. The Participant understands and agrees that he or she will not be able to participate in the Plan if the Participant fails to provide any such consent or agreement requested by the Company and/or the Employer. 20. Acquired Rights. The Participant acknowledges and agrees that: (a) the Company may terminate or amend the Plan at any time; (b) the award of the Performance Stock Units made under this Performance Stock Unit Agreement is completely independent of any other award or grant and is made at the sole discretion of the Company; (c) no past grants or awards (including, without limitation, the Performance Stock Units awarded hereunder) give the Participant any right to any grants or awards in the future whatsoever; and (d) any benefits granted under this Agreement are not part of the Participant's ordinary salary, and shall not be considered as part of such salary in the event of severance, redundancy or resignation. 21. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company. 22. Entire Agreement. This Performance Stock Unit Agreement (including, without limitation, any Exhibit attached hereto), the Grant Notice and the Plan constitute the entire agreement of the parties hereto in respect of the subject matter contained herein and supersede all prior agreements and understandings of the parties, oral and written, with respect to such subject matter. [However, unless otherwise stated therein, the Restrictive Covenant Agreement will not be considered to supersede any prior non-competition, non-solicitation, or non-disclosure agreement between Participant and the Company, which will remain in effect, and be read in conjunction with the Restrictive Covenant Agreement and any future agreements on the same subject matter, so as to afford the Company the broadest protections allowed under applicable law.] \* \* \*

(the "Company") and the Participant agree as follows. Capitalized terms not otherwise defined herein shall have the same meaning as set forth in the Plan. 1. Grant of Restricted Stock Units.

The Company reserves all rights with respect to the granting of additional Restricted Stock Units hereunder and makes no implied promise to grant additional Restricted Stock Units. 2. Vesting. (a) Subject to the conditions contained herein and in the Plan, the Restricted Stock Units shall vest as provided in the Grant Notice. (b) [In the event of a Change in Control, provided that the Participant has not undergone a Termination prior to occurrence thereof, any unvested Restricted Stock Units will become vested as of immediately prior to such Change in Control.] [Notwithstanding the foregoing, in the event of a Change in Control, any unvested Restricted Stock Units that are assumed by the acquiror in the Change in Control will remain outstanding and subject to vesting; provided, however, that in the event the Participant's employment terminates within [ ] years following a Change in Control due to either (i) a termination by the Company without Cause or (ii) a resignation by the Participant with Good Reason, any unvested Restricted Stock Units will immediately vest as of the date of termination.

(ii) If the Retirement Date occurs on or following the [ ] anniversary of the Grant Date but prior to the [ ] anniversary of the Grant Date, the Restricted Stock Units shall continue to vest, and Participant shall be entitled to receive a pro rata portion of the number of unvested Restricted Stock Units that otherwise would have vested in accordance with Section 2(a) had the Participant been employed as of the applicable vesting date (such amount, the "Pro Rata Amount"). The Pro Rata Amount shall equal: the number of Restricted Stock Units that otherwise would have vested on the next vesting date following the date of the Participant's Termination due to Retirement had the Participant been employed on such vesting date, multiplied by a fraction, (A) the numerator of which is the number of completed months from the most recent vesting date through the last completed month prior to the Retirement Date, and (B) the denominator of which is 12. Any Restricted Stock Units that become vested as a result of this paragraph shall settle following the applicable vesting date in accordance with Section 3.] (f) [For purposes of Section 2(e), "Retirement" means, with respect to the Participant, such Participant's voluntary Termination on or after of the date on which (i) such Participant's age plus years of continuous service with the Company or one of its Subsidiaries equals at least 65 and (ii) the Participant is at least age 55 and has completed at least five years of continuous service with the Company or one of its Subsidiaries.] 3.

&nbsp;&nbsp;&nbsp;&nbsp;3 each Restricted Stock Unit (as adjusted under the Plan, as applicable) which becomes vested hereunder and such vested Restricted Stock Unit shall be cancelled upon such delivery. The Company shall either (a) deliver, or cause to be delivered, to the Participant a certificate or certificates therefor, registered in the Participant's name or (b) cause such shares of Common Stock [(or corresponding acquiror shares, as applicable)] to be credited to the Participant's account at the third-party stock plan administrator.

Rights as Shareholder; Dividend Equivalents. The Participant shall have no rights as a shareholder with respect to any share of Common Stock underlying a Restricted Stock Unit unless and until the Participant shall have become the holder of record or the beneficial owner of such share of Common Stock, and no adjustment shall be made for dividends or distributions or other rights in respect of such share of Common Stock for which the record date is prior to the date upon which the Participant shall become the holder of record or the beneficial owner thereof. The Restricted Stock Units shall be entitled to be credited with dividend equivalent payments upon the payment by the Company of dividends on shares of Common Stock. Such dividend equivalents will be provided in shares of Common Stock having a Fair Market Value on the date that the Restricted Stock Units are settled equal to the amount of such applicable dividends, and shall be payable at the same time as the Restricted Stock Units are settled in accordance with Section 3 above. In the event that any Restricted Stock Unit is forfeited by its terms, the Participant shall have no right to dividend equivalent payments in respect of such forfeited Restricted Stock Units.

Exhibit A constitutes part of this Restricted Stock Unit Agreement. 19. Data Privacy Acknowledgment. By electing to participate in the Plan via the Company's acceptance procedures, the Participant is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Personal Data (as defined below) by the Company and the transfer of Personal Data to the recipients mentioned herein, including recipients located in countries which do not adduce an adequate level of protection from a European (or other) data protection law perspective, for the purposes described herein. (a) Declaration of Consent. The Participant understands that he or she needs to review the following information about the processing of his or her personal data by or on behalf of the Company, the Participant's employer or contracting party (the "Employer") and/or any Subsidiary as described in this Restricted Stock Unit Agreement and any other Plan materials (the "Personal Data") and declare his or her consent.

![](form2026rsuagreementempl009.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;7 Units or any other entitlement to shares of stock or equivalent benefits awarded, cancelled, exercised, vested, unvested or outstanding in the Participant's favor. The legal basis for the processing of the Participant's Personal Data, where required, will be his or her consent. (c) Stock Plan Administration Service Providers. The Participant understands that the Company may transfer his or her Personal Data, or parts thereof, to a third-party stock plan administrator (and its affiliated companies, as applicable) based in the United States which will assist the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Participant's Personal Data with such different service provider that serves the Company in a similar manner. The Participant understands and acknowledges that the Company's service provider will open an account for him or her to receive and trade shares of Common Stock acquired under the Plan and that he or she will be asked to agree on separate terms and data processing practices with the service provider, which is a condition of the Participant's ability to participate in the Plan.

The Participant understands and acknowledges that his or her country may have enacted data privacy laws that are different from the laws of the United States. For example, the European Commission has issued only a limited adequacy finding with respect to the United States that applies solely if and to the extent that companies self-certify and remain self-certified under the EU/U.S. Privacy Shield program. The Company currently participates in the EU/U.S. Privacy Shield Program. The Company's legal basis for the transfer of the Participant's Personal Data is his or her consent. (e) Data Retention. The Participant understands that the Company will use his or her Personal Data only as long as is necessary to implement, administer and manage his or her participation in the Plan, or to comply with legal or regulatory obligations, including under tax and securities laws. In the latter case, the Participant understands and acknowledges that the Company's legal basis for the processing of his or her Personal Data would be compliance with the relevant laws or regulations. When the Company no longer needs the Participant's Personal Data for any of the above purposes, the Participant understands the Company will remove it from its systems.

The Participant may deny or later withdraw his or her consent at any time, with future effect and for any or no reason. If the Participant denies or later withdraws his or her consent, the Company can no longer offer the Participant participation in the Plan or offer other equity awards to the Participant or administer or maintain such awards and the Participant would no longer be able to participate in the Plan. The Participant further understands that denial or withdrawal of his or her consent would not affect his or her status or salary as an employee or his or her career and that the Participant would merely forfeit the opportunities associated with the Plan. (g) Data Subject Rights. The Participant understands that data subject rights regarding the processing of Personal Data vary depending on the applicable law and that,

------

![](form2026rsuagreementempl010.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;8 depending on where the Participant is based and subject to the conditions set out in the applicable law, the Participant may have, without limitation, the rights to (i) inquire whether and what kind of Personal Data the Company holds about him or her and how it is processed, and to access or request copies of such Personal Data, (ii) request the correction or supplementation of Personal Data about him or her that is inaccurate, incomplete or out-of-date in light of the purposes underlying the processing, (iii) obtain the erasure of Personal Data no longer necessary for the purposes underlying the processing, processed based on withdrawn consent, processed for legitimate interests that, in the context of his or her objection, do not prove to be compelling, or processed in non-compliance with applicable legal requirements, (iv) request the Company to restrict the processing of his or her Personal Data in certain situations where the Participant feels its processing is inappropriate, (v) object, in certain circumstances, to the processing of Personal Data for legitimate interests, and to (vi) request portability of the Participant's Personal Data that he or she has actively or passively provided to the Company (which does not include data derived or inferred from the collected data), where the processing of such Personal Data is based on consent or his or her employment and is carried out by automated means. In case of concerns, the Participant understands that he or she may also have the right to lodge a complaint with the competent local data protection authority. Further, to receive clarification of, or to exercise any of, the Participant's rights, the Participant understands that he or she should contact his or her local human resources representative. (h) Alternate Basis and Additional Consents. Finally, the Participant understands that the Company may rely on a different basis for the collection, processing or transfer of Personal Data in the future and/or request that the Participant provide another data privacy consent. If applicable, the Participant agrees that upon request of the Company or the Employer, the Participant will provide an executed acknowledgment or data privacy consent form (or any other agreements or consents) that the Company and/or the Employer may deem necessary to obtain from him or her for the purpose of administering his or her participation in the Plan in compliance with the data privacy laws in his or her country, either now or in the future. The Participant understands and agrees that he or she will not be able to participate in the Plan if the Participant fails to provide any such consent or agreement requested by the Company and/or the Employer. 20. Acquired Rights. The Participant acknowledges and agrees that: (a) the Company may terminate or amend the Plan at any time; (b) the award of the Restricted Stock Units made under this Restricted Stock Unit Agreement is completely independent of any other award or grant and is made at the sole discretion of the Company; (c) no past grants or awards (including, without limitation, the Restricted Stock Units awarded hereunder) give the Participant any right to any grants or awards in the future whatsoever; and (d) any benefits granted under this Agreement are not part of the Participant's ordinary salary, and shall not be considered as part of such salary in the event of severance, redundancy or resignation. 21. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company. 22. Entire Agreement. This Restricted Stock Unit Agreement [(including, without limitation, any Exhibit attached hereto)], the Grant Notice and the Plan constitute the

------

&nbsp;&nbsp;&nbsp;&nbsp;9 entire agreement of the parties hereto in respect of the subject matter contained herein and supersede all prior agreements and understandings of the parties, oral and written, with respect to such subject matter. [However, unless otherwise stated therein, the Restrictive Covenant Agreement will not be considered to supersede any prior non-competition, non-solicitation, or non-disclosure agreement between Participant and the Company, which will remain in effect, and be read in conjunction with the Restrictive Covenant Agreement and any future agreements on the same subject matter, so as to afford the Company the broadest protections allowed under applicable law.] \* \* \*

I understand and acknowledge that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal, State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. I understand and acknowledge further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Except as provided in this paragraph or under applicable law, under no circumstance am I authorized to disclose any information covered by Avantor's attorney-client privilege or attorney work product, or trade secrets, without prior written consent of Avantor. 6. Assignment of Inventions. I will make prompt and full disclosure to Avantor, will hold in trust for the sole benefit of Avantor, and will assign, exclusively to Avantor, all my right, title, and interest in and to any and all inventions, discoveries, designs, developments, improvements, copyrightable material, and trade secrets (collectively herein "Inventions") that I, solely or jointly, may conceive, develop, or reduce to practice during the period of time I am in the employ of Avantor. I hereby waive and quitclaim to Avantor any and all claims of any nature whatsoever that I now or hereafter may have for infringement of any patent resulting from any patent applications for any Inventions so assigned to Avantor.

------

![](benoitemploymentletterco011.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;3 My obligation to assign shall not apply to any Inventions about which I can prove that: (a) it was developed entirely on my own time; and (b) no equipment, supplies, facility, services, or trade secret information of Avantor were used in its development; and (c) it does not relate (i) directly to the business of Avantor or (ii) to the actual or demonstrably anticipated research or development of Avantor; and (d) it does not result from any work performed by me for Avantor. 7. Excluded and Licensed Inventions. I have attached hereto a list describing all Inventions belonging to me and made by me prior to my employment with Avantor that I wish to have excluded from this Agreement. If no such list is attached, I represent that there are no such Inventions. If in the course of my employment at Avantor, I incorporate into a Company product, process, or machine, an Invention owned by me or in which I have an interest, Avantor is hereby granted and shall have an exclusive royalty-free, irrevocable, worldwide license to make, have made, use, and sell that Invention without restriction as to the extent of my ownership or interest. 8. Application for Copyrights and Patents. I will execute any proper oath or verify any proper document in connection with carrying out the terms of this Agreement. If, because of my mental or physical condition or for any other reason whatsoever, Avantor is unable to secure my signature to apply for or to pursue any application for any United States or foreign patent or copyright covering Inventions assigned to Avantor as stated above, I hereby irrevocably designate and appoint Avantor and its duly authorized officers and agents as my agent and attorney in fact, to act for me and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of U.S. and foreign patents and copyrights thereon with the same legal force and effect as if executed by me. I will testify at Avantor's request in any interference, litigation, or other legal proceeding that may arise during or after my employment and my reasonable expenses associated with said testimony will be paid by Avantor. 9. Third Party Information. I recognize that Avantor has received and will receive confidential or proprietary information from third parties subject to a duty on Avantor's part to maintain the confidentiality of such information and to use it only for certain limited purposes. This information shall be deemed not to include any information that is or becomes publicly known or that enters the public domain other than as a result of my breach of my obligations under this Agreement or any other agreement between me and Avantor. During the term of my employment and thereafter I will not disclose nor use such information for the benefit of anyone other than Avantor or such third party, or in any manner inconsistent with any agreement between Avantor and such third party of which I am made aware, except as is required by law, any court of competent jurisdiction or any governmental agency or authority or recognized subpoena power. 10. Termination. I acknowledge that this Agreement shall not constitute a contract for employment for any specific period of time, and that either Avantor or I am free to terminate employment, "at will," at any time, with or without cause. I agree that upon termination of my employment, for any or no reason, I will promptly return to Avantor all records of Confidential Information, including copies in my possession, and all other physical properties issued to me

------

![](benoitemploymentletterco012.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;4 as an employee, in a reasonable state of function or repair. I will also so return any keys, pass cards, identification cards or other property belonging to Avantor. Returning all Company property is a condition of receiving severance benefits, if any. 11. Non-Waiver. The failure by Avantor to enforce any of the provisions hereof upon any default by me at a particular time or under certain circumstances shall not be treated as a permanent waiver of such provisions and shall not prevent subsequent enforcement of such provisions upon default by either party. 12. Irreparable Harm. I agree that any proven breach of this Agreement by me would cause irreparable harm to Avantor for which monetary damages could not adequately compensate. If Avantor proves a breach, irreparable harm shall be presumed, and I expressly waive any bonding requirement as a prerequisite to Avantor obtaining injunctive relief. Avantor can also seek damages and attorneys' fees. 13. Assignability of This Agreement. The services contracted for between Avantor and me in this Agreement are personal, and therefore I may not assign this Agreement to any other person or entity. This Agreement may, however, be assigned by Avantor to a successor to the business of Avantor or to an affiliate of Avantor. 14. Severability. It is the intention of the parties that this Agreement shall be enforceable to the fullest extent permitted by local, State, and/or Federal law in the jurisdiction in which performance of this Agreement occurs, or in which performance of this Agreement is sought to be enforced. In the event that a court of competent jurisdiction determines that one or more provisions of this Agreement are not enforceable under the provisions of the jurisdiction in which performance occurs or enforcement is sought, such a determination shall not affect the enforceability of the remainder of this Agreement. 15. Other Agreements. This Agreement, together with the Letter Agreement, including the Annexes attached thereto, dated July __, 2023, between me and Avantor (the "Letter Agreement"), set forth the sole and entire agreement between the parties hereto, and supersedes and replaces any and all prior agreements, whether oral, written, or implied, entered into by me and Avantor, pertaining to my employment, the terms, conditions, and responsibilities thereof, and/or any other subject matter contained in this Agreement or the Letter Agreement. This Agreement and the Letter Agreement, including all Annexes, shall be considered together as one agreement. There will be no modification of this Agreement, either verbal, implied, written, or otherwise, except through a written agreement signed by me, and an officer of Avantor, which refers to the specific paragraph of this Agreement intended to be modified, and sets forth, in writing, the specific modification of said paragraph. This Agreement and the Letter Agreement, including all Annexes, will supersede and preempt all prior oral or written understandings and agreements with respect to the subject matter hereof and thereof between me and Avantor and its affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Annex 1 - Employee Covenants 1. Noncompetition, Non-solicitation and non-disparagement. You acknowledge that in the course of your employment with Avantor or any of its Subsidiaries or Affiliates you will become familiar with Avantor's and its Subsidiaries' and Affiliates' trade secrets and with other confidential information concerning Avantor and such Subsidiaries and Affiliates and that your services will be of special, unique, and extraordinary value to Avantor and such Subsidiaries and Affiliates. Therefore, you agree that: (a) Noncompetition. During the Employment Period and for a period of twelve (12) months thereafter, you shall not directly or indirectly, anywhere in the world, own, manage, control, participate in, consult with, render services for or enter into employment with any business or organization that competes with the business that Avantor or any of its Subsidiaries or Affiliates is engaged in at the time of your Separation (the "Business"). Nothing herein shall prohibit you from being a passive owner of not more than 2% of the outstanding stock of any class of a corporation that is publicly traded, so long as you have no active participation in the business of such corporation. (b) Non-solicitation. During the Employment Period and for a period of twenty- four (24) months thereafter, you shall not directly or indirectly (i) induce or attempt to induce any employee of Avantor or any of its Subsidiaries or Affiliates to leave the employ of Avantor or any such Subsidiary or Affiliate, or in any way interfere with the relationship between Avantor or any of its Subsidiaries or Affiliates and any employee thereof, (ii) hire any person who was an employee of Avantor or any of its Subsidiaries or Affiliates within one hundred eighty (180) days after a Separation, (iii) induce or attempt to induce any customer, supplier, licensee or other business relation of Avantor or any of its Subsidiaries or Affiliates to cease doing business with Avantor or such Subsidiary or Affiliate or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and Avantor or any of its Subsidiaries or Affiliates or (iv) directly or indirectly acquire or attempt to acquire an interest in any business relating to the Business and with which Avantor or any of its Subsidiaries or Affiliates has entertained discussions relating to the acquisition of such business by Avantor or any of its Subsidiaries or Affiliates in the twelve month (12) period immediately preceding a Separation. (c) Non-disparagement. During the Employment Period and at any time thereafter, you shall not disparage Avantor or any of its Subsidiaries or Affiliates or any officer, employee, director, shareholder or member of Avantor Subsidiaries or Affiliates. (d) Enforcement. If, at the time of enforcement of Section 1 or 2, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum duration, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum duration, scope and area permitted by law. Because your services are unique and because you have access to confidential information, the parties hereto agree that money damages would be an inadequate remedy for any breach of this Annex 1. Therefore, in the event a breach or threatened breach of this Annex 1, Avantor or any of its Subsidiaries or Affiliates or their successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security).

------

![](benoitemploymentletterco015.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;2 (e) Additional Acknowledgments. You acknowledge that the provisions of Sections 1 and 2 are in consideration of: (i) employment with Avantor or its Subsidiaries or Affiliates and (ii) additional good and valuable consideration, including the payment of salary and bonus, as set forth in this Letter Agreement. In addition, you agree and acknowledge that the restrictions contained in Sections 1 and 2 do not preclude you from earning a livelihood, nor do they unreasonably impose limitations on your ability to earn a living. In addition, you acknowledge (A) that the business of Avantor and its Subsidiaries and Affiliates will be conducted throughout the world, (B) notwithstanding the state of incorporation or principal office of Avantor or any of its Subsidiaries or Affiliates, or any of their respective executives or employees (including you), it is expected that Avantor and its Subsidiaries and Affiliates will have business activities and have valuable business relationships within its industry throughout the world, and (C) as part of your responsibilities, you will be traveling throughout the world in furtherance of Avantor's or any of its Subsidiaries' or Affiliates' business and relationships. You agree and acknowledge that the potential harm to Avantor and any of its Subsidiaries and Affiliates of the non-enforcement of Sections 1 and 2 outweighs any potential harm to you of its enforcement by injunction or otherwise. You acknowledge that you have carefully read this Annex 1 and have given careful consideration to the restraints imposed upon you by this Annex 1, and are in full accord as to their necessity for the reasonable and proper protection of confidential and proprietary information of Avantor and any of its Subsidiaries and Affiliates now existing or to be developed in the future.

&nbsp;&nbsp;&nbsp;&nbsp;4 agree that service of any process, summons, notice or document by certified or registered mail to your address as listed above or such other address or to the attention of such other person as you have specified by prior written notice to Avantor shall be effective service of process in any action, suit or proceeding in the Commonwealth of Pennsylvania with respect to any matters to which you have submitted to jurisdiction as set forth above in the immediately preceding sentence.

(c) Additional Agreements. The provisions of this Annex 1 are in addition to, and do not supersede, the provisions of the Personal Services, Confidentiality, and Inventions Agreement between you and Avantor. (d) MUTUAL WAIVER OF JURY TRIAL.

I understand that any payments or benefits paid or granted to me under the "Severance/Restrictive Covenants" section of the Letter Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive the payments and benefits specified in the "Severance/Restrictive Covenants" section of the Letter Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter or breach this General Release. I also acknowledge and represent that I have received all payments and benefits that I am entitled to receive (as of the date hereof) by virtue of any employment by the Company. 2. Except as provided in paragraph 4 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys' fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any other Federal, State or local civil or human rights law, or under any other local, State, or Federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys' fees incurred in these matters) (all of the foregoing collectively referred to herein as the "Claims"). 3. I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above. 4. I agree that this General Release does not waive or release any rights or claims that I may have which arise after the date I execute this General Release. I acknowledge and agree that my

------

![](benoitemploymentletterco019.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;2 separation from employment with the Company is in compliance with the terms of the Letter Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 5. In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims. I further agree that I am not aware of any pending claim of the type described in paragraph 2 as of the execution of this General Release. 6. I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct. 7. I agree that this General Release and the Letter Agreement are confidential and agree not to disclose any information regarding the terms of this General Release or this Letter Agreement, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or effect hereof or as required by law, and I will instruct each of the foregoing not to disclose the same to anyone. Notwithstanding anything herein to the contrary, each of the parties (and each affiliate and person acting on behalf of any such party) agree that each party (and each employee, representative, and other agent of such party) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of this transaction contemplated in the Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to such party or such person relating to such tax treatment and tax structure, except to the extent necessary to comply with any applicable federal or state securities laws. This authorization is not intended to permit disclosure of any other information including (without limitation) (i) any portion of any materials to the extent not related to the tax treatment or tax structure of this transaction, (ii) the identities of participants or potential participants in the Agreement, (iii) any financial information (except to the extent such information is related to the tax treatment or tax structure of this transaction), or (iv) any other term or detail not relevant to the tax treatment or the tax structure of this transaction. 8. I understand that any non-disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release or its underlying facts and circumstances by the Securities and Exchange Commission (SEC), the National Association of Securities Dealers, Inc. (NASD), any other self-regulatory organization or governmental entity. Furthermore, I understand that nothing in this Agreement shall prohibit or impede me from communicating, cooperating or filing a complaint with any U.S. Federal, State or local governmental or law enforcement branch, agency or entity (collectively, a "Governmental Entity") with respect to possible violations of any U.S. Federal, State or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or

------

![](benoitemploymentletterco020.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;3 regulation, provided that in each case such communications and disclosures are consistent with applicable law. I understand and acknowledge that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal, State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. I understand and acknowledge further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Except as provided in this paragraph or under applicable law, under no circumstance am I authorized to disclose any information covered by the Company's attorney-client privilege or attorney work product, or trade secrets, without prior written consent of the Company. 9. Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after the date hereof. 10. Whenever possible, each provision of this General Release shall be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 11. By execution of this Agreement, I expressly waive any and all rights or claims arising under the Age Discrimination in Employment Act of 1967 ("ADEA) and: (a) I acknowledge that my waiver of rights or claims arising under the ADEA is in writing and is understood by me; (b) I expressly understand that this waiver refers to rights or claims arising under the ADEA; (c) I expressly understand that by execution of this General Release, I do not waive any rights or claims under the ADEA that may arise after the date the waiver is executed; (d) I acknowledge that the waiver of my rights or claims arising under the ADEA is in exchange for the consideration outlined in the Letter Agreement, which is substantially above and beyond that to which I am entitled; (e) I acknowledge that the Company expressly advised me to consult with an attorney of my choosing prior to executing this General Release; (f) I have been advised by the Company that I have a period of at least twenty-one (21) days within which to consider this General Release after it is presented to me; (g) I acknowledge I have been advised by the Company that I am entitled to revoke (in the event I execute this General Release) my waiver of rights or claims arising under the ADEA within seven (7) days after executing and that said

&nbsp;&nbsp;&nbsp;&nbsp;4 waiver will not and does not become effective or enforceable until the seven (7) day revocation period has expired; (h) I understand that this waiver is not requested in connection with an exit incentive or other employment termination program; (i) I acknowledge, notwithstanding any other provision to the contrary, that no sums or benefits due me under the Letter Agreement shall be paid or provided until the revocation period specified in subparagraph (g) hereof has expired without me exercising my right to revoke and all Company property has been returned to the Company by me.
