ITEM 1. BUSINESS

Business Overview

We are an innovator of materials solutions to help our customers succeed, while enabling a sustainable world. Our products include specialty engineered materials, performance fibers, advanced composites and color and additive solutions. We are also a highly specialized developer and manufacturer of performance enhancing additives, liquid colorants and silicone colorants. When used in this Annual Report on Form 10-K, the terms “we,” “us,” “our," "Avient" and the “Company” mean Avient Corporation and its consolidated subsidiaries.

Avient was formed as PolyOne Corporation on August 31, 2000, from the consolidation of The Geon Company (Geon) and M.A. Hanna Company (Hanna). Through a series of acquisitions, divestitures, operational improvements and cultural shifts, the Company has transformed to become an innovator of materials solutions. Effective June 30, 2020, the Company amended its existing Articles of Incorporation to change its name to Avient Corporation and changed its ticker symbol from “POL” to “AVNT”, effective at the start of trading on July 13, 2020.

Avient Corporation is incorporated in Ohio and headquartered in Avon Lake, Ohio. We currently have 98 manufacturing sites in North America, South America, Asia, Europe, the Middle East, and Africa (EMEA). In 2025, the Company had sales of $3.3 billion, approximately 61% of which were to customers outside the United States. Using formulation expertise, materials science and operational capabilities, we create an essential link between large chemical producers (our raw material suppliers) and designers, assemblers and processors of polymers (our customers). We believe that our role in the value chain continues to become more vital as our customers increasingly need reliable suppliers with global reach, a local touch, and highly effective materials-based solutions to help improve their products' performance, appeal, differentiation, profitability and competitive advantage. Our goal is to provide customers with innovative materials solutions through our global footprint, broad market knowledge, technical expertise, product breadth, manufacturing operations and raw materials procurement leverage. Our end markets include consumer, packaging, defense, healthcare, industrial, transportation, building and construction, telecommunications and energy.

Polymer Industry Overview

Avient is an innovator of materials solutions within the polymer industry. We have the scientific know-how in materials science required to bridge the large, commodity base resin producers and the companies who ultimately manufacture end products utilizing formulated polymer and composite materials.

Polymers are a class of organic materials that are generally produced by converting natural gas or crude oil derivatives into monomers, such as ethylene, propylene, and styrene. These monomers are then polymerized into chains called polymers, or plastic resin, such as polyethylene and polypropylene, in their most basic forms. Avient does not produce commodity base resins. Rather, Avient sources various resins, polymers and additives, then employs additional chemistry in formulating those materials into highly engineered, unique materials for a specific use.

Thermoplastic polymers are characterized by their ability to be reshaped repeatedly into new forms after heat and pressure are applied. Thermoplastics offer versatility and a wide range of applications. The major types of thermoplastics include polyethylene, polypropylene, polystyrene, polyester and a range of specialized engineering resins. Each type of thermoplastic has unique qualities and characteristics that make it appropriate for use in a particular application.

Thermoplastic composites include base resins, but are combined with a structural element such as glass, carbon or polymer fibers to enhance strength, rigidity and structure. Further performance can be delivered through an engineered thermoplastic sheet or thick film, which may incorporate more than one resin formulation or composite in multiple layers to impart additional properties, such as gas barrier, structural integrity and lightweighting.

Thermoplastics and polymer composites are found in a variety of end-use products and markets, including packaging, defense, building and construction, wire and cable, transportation, medical, furniture and furnishings, durable goods, outdoor high-performance equipment, electrical and electronics, adhesives, inks and coatings and fiber. Each type of thermoplastic resin has to ultimately achieve unique characteristics (such as flexibility, strength or durability) suitable for use in a particular end-use application. The materials science and manufacturing processes required to achieve those characteristics is the specialty role that Avient plays.

2 AVIENT CORPORATION

The following are examples, by industry, where Avient materials solutions address specific market requirements or challenges. In the packaging industry, colorants and additives are used to lightweight, enhance consumer appeal, increase design freedom, improve recyclability, enable recycled content to be incorporated, and preserve and protect the packaging's contents. In wire and cable, thermoplastics and composites enhance performance and extend product life by providing electrical insulation, flame resistance, water resistance and strain resistance for highly engineered electrical and telecommunications wires, cables and connectors. In the defense industry, ultra-high molecular weight fiber is relied upon and incorporated into tactical vests, hard armor plates, shields, bomb suits, helmets, and military vehicles (air, sea and ground). In the transportation industry, plastic has proven to be durable, lightweight and corrosion resistant while offering fuel savings, design flexibility and high performance, often replacing traditional materials such as metal and glass. In the medical industry, plastics are used for a vast array of devices and equipment, including blood and intravenous bags, medical tubing, catheters, lead replacement for radiation shielding, clamps and connectors to bed frames, curtains and sheeting, electronic enclosures and equipment housing. In the outdoor high performance industry, plastic applications are used for components and colorants for all terrain vehicles, and reinforced polymers are used for various outdoor equipment and gear. In the electronics industry, plastic enclosures and connectors not only enhance safety through electrical insulation, but thermally and electrically conductive plastics provide heat transferring, cooling, anti-static, electrostatic discharge, and electromagnetic shielding performance for critical applications including integrated circuit chip packaging.

Various additives can also be formulated with a base resin and further engineered into a composite to provide them with greater versatility and performance. Polymer formulations and composites have advantages over metals, wood, rubber, glass and other traditional materials, which have resulted in the replacement of these materials across a wide spectrum of applications. These specialized polymers offer sustainability and performance advantages compared to traditional materials, including design freedom, processability, weight reduction, chemical resistance, flame retardance and lower cost. Plastics are renowned for their durability, aesthetics and ease of handling. Avient’s strategy and investments are aligned to enable these important benefits, now and in the future.

Avient Segments

We operate in two reportable segments: (1) Color, Additives and Inks and (2) Specialty Engineered Materials. Our segments are further detailed in Note 13, Segment Information, to the accompanying consolidated financial statements.

Competition

We compete with global companies and local niche producers on performance, innovation, service, quality, delivery, and price. Our strategy is to focus our technologies where they intersect secular growth trends and to build platforms of scale that differentiate on speed, global reach, and application expertise.

Raw Materials

We primarily purchase polyolefin and other thermoplastics, titanium dioxide, pigments, specialty additives, and ethylene for use in our manufacturing operations, all of which we believe are currently in adequate supply. See the discussion of risks associated with raw material supply and costs in Item 1A, “Risk Factors."

Patents and Trademarks

We own and maintain a number of patents and trademarks in the United States and other key countries that contribute to our competitiveness in the markets we serve because they protect our inventions and product names against infringement by others. Patents may exist for 20 years from filing date, and trademarks may have an indefinite life based upon continued use. While we view our patents and trademarks to be valuable because of the broad scope of our products and services and brand recognition we enjoy, we do not believe that the loss or expiration of any single patent or trademark would have a material adverse effect on our results of operations, financial position or cash flows. Nevertheless, we have management processes designed to rigorously protect our inventions and trademarks.

Seasonality

Sales of our products and services are typically seasonal, as demand has historically been slower in the third and fourth quarters of the calendar year. In addition, our defense business is, in part, associated with tenders and project-based work, which can lead to inconsistent order patterns on a quarter over quarter basis.

3 AVIENT CORPORATION

Working Capital Practices

Our products are generally manufactured with a short turnaround time, and the scheduling of manufacturing activities from customer orders generally includes enough lead time to assure delivery of an adequate supply of raw materials. We agree to payment terms with our customers and suppliers that are competitive.

Significant Customers

No customer accounted for more than 3% of our consolidated revenues in 2025.

Research and Development

One of our strategic drivers is to "Amplify Innovation," and we have substantial technology and development capabilities, powered by approximately 1,100 employees serving in technical capacities, approximately 120 of whom have PhD level educations. Our efforts are largely devoted to developing new materials solutions to address evolving market and sustainability needs. We do this by providing quality technical services to evaluate alternative raw materials, facilitating the continued success of our products for customer applications, providing technology to improve our products, processes and applications and providing support to our manufacturing plants for cost reduction, productivity and quality improvement programs. We operate research and development centers that support our commercial development activities and manufacturing operations. These facilities are equipped with state-of-the-art analytical, synthesis, polymer characterization and testing equipment, along with pilot plants and polymer manufacturing operations that simulate specific production processes. Our investment in product research and development was $96.7 million in 2025, $98.7 million in 2024, and $90.3 million in 2023.

Methods of Distribution

We sell products primarily through direct sales personnel, distributors, and commissioned sales agents. We primarily use truck carriers to transport our products to customers, although some customers pick up product at our manufacturing facilities or warehouses.

Human Capital Resources

The success and growth of our business depend in large part on our ability to attract, develop and retain talented and high-performing employees at all levels of our organization. We are committed to building additional capabilities within our organization to meet the changing needs of our customers and the dynamic macro environment in which we operate.

We have developed key recruitment and retention strategies, objectives and measures that guide our human capital management approach as part of the overall management of our business. These strategies, objectives and measures are advanced through a number of programs, policies and initiatives, as described below.

As of December 31, 2025, Avient employed approximately 9,000 people, 33% of which were located in the U.S. and Canada, 33% were located in EMEA, 26% were located in Asia, and 8% were located in Latin America.

Safety and Health

A top priority at Avient is the safety and health of our employees, and our ultimate goal is to operate injury free. Progress toward this goal is measured at the business unit and regional levels, communicated globally, and linked to a number of recognition programs. In 2025, we continued our strong focus on safety with a recordable incident rate of 0.60 per 100 full-time workers per year, compared to the Plastics and Rubber Products Manufacturing industry (NAICS Code 326) average of 2.80 in 2024. Continuous improvement and preventative risk reductions are key focus areas, including the active engagement of our employees in safety activities. We also continue to be recognized as an American Chemistry Counsel Responsible Care® company and set high standards for our operations as we strive to achieve our goal of zero recordable injuries.

Employee Recruitment

Avient’s success is driven by having the best talent in the right roles. We actively seek collaborative and innovative change-makers who are passionate about our strategy and values through numerous channels, including employee referrals, job fairs, talent networks, industry associations, and directly from universities. As a key aspect of our talent pipeline, we partner with leading universities around the world to hire employees into full-time, co-op and internship opportunities. These roles include rotational development programs where individuals are able to gain experience in various departments and jobs within or across functions, contributing their skills while also building well-rounded knowledge of our Company and its many stakeholders.

Our talented people leverage their unique backgrounds across a myriad of aspects and skills toward a common goal: meeting the needs of the present without compromising the ability of future generations to do the same. This spirit of inclusive collaboration can be felt throughout our Company. It drives the innovation that earns us leadership positions in the markets we serve and underpins the high level of respect we show each other every day.

The vision that guides our collective efforts is consistent and unwavering: to be the Company of choice for all. We leverage Employee Resource Groups to help educate and inspire our global workforce and fortify strong business practices. Other initiatives, including Mentoring at Avient and campus partnerships, are vital for progress in our inclusion journey. We require equality of opportunity for all qualified individuals in accordance with applicable laws.

Decisions on hiring, promotion, development, compensation or advancement are based solely on a person’s qualifications, abilities, experience and performance, except where local law requires us take specific action. The Avient Ethics Hotline serves as a mechanism for employees to anonymously report any perceived concerns regarding these topics.

Compensation and Benefits Programs

We strive to remain competitive in the global marketplace and provide foundational rewards to attract and retain top talent. In general, our overall philosophy on compensation encompasses the following principles:

•provide all levels of employees with a compensation package that aligns Avient’s and the employees’ interests through the use of base and incentive or bonus programs;

•maintain a competitive pay program that serves to attract, retain, motivate and reward employees; and

•award individual pay commensurate with experience, level of responsibility, and marketability.

We celebrate, reward and share our employees’ great work through our recognition programs, including those that all employees can earn for their extra effort and impact. In addition, we provide our employees an opportunity to support communities by giving each individual 16 hours of paid time off each year. In 2025, all of our sites and more than 6,000 employees generously gave over 13,000 volunteer hours and $1.4 million in donations around the world.

A Great Place to Work®

Our ongoing employee feedback is highly valued, discussed, and most importantly, acted upon, to make improvements. In addition to holding action planning sessions, new manager assimilations, and 360 reviews, we also conduct annual employee engagement surveys. Last year, we continued to focus on our action plans for each site location and team to improve the experience and engagement of our global teams. We are proud that our employees feel we are a Great Place to Work®, as evidenced by our six Great Place to Work® certifications. Understanding how our employees feel about their experiences at Avient and our culture is critical and helps us ensure that the right capabilities and behaviors are developed across the organization.

5 AVIENT CORPORATION

Environmental, Health and Safety and Other Regulations

We are also subject to extensive and varied laws and regulations in the jurisdictions in which we operate, including those relating to anti‑corruption and trade, anti-money laundering, import and export compliance, antitrust, data security and privacy, employment, public health and safety, intellectual property, transportation, zoning, and fire codes. Our policies mandate compliance with all applicable laws and regulations, and we operate our business in accordance with standards and procedures designed to comply with these laws and regulations. We believe that we are in compliance with such laws and regulations in all material respects.

We are strongly committed to safety as evidenced by our low injury incidence rate of 0.60 per 100 full-time workers per year in 2025 and 0.40 in 2024. The 2024 average injury incidence rate for our NAICS Code (326 Plastics and Rubber Products Manufacturing) was 2.80. We hold the American Chemistry Council's certification as a Responsible Care Management System® (RCMS) company. Certification was granted based on Avient's conformance to the RCMS's comprehensive environmental health, safety and security requirements. The RCMS certification affirms the importance Avient places on having strong environmental, health, safety and security performance. In our operations, we must comply with product-related governmental law and regulations affecting the plastics industry generally and also with content-specific law, regulations and non-governmental standards. We believe that compliance with current governmental laws and regulations and with non-governmental content-specific standards will not have a material adverse effect on our financial position, results of operations or cash flows. The risk of additional costs and liabilities, however, is inherent in certain plant operations and certain products produced at these plants, as is the case with other companies in the plastics industry. Therefore, we may incur additional costs or liabilities in the future. Other developments, such as increasingly strict environmental, safety and health laws, regulations and related enforcement policies, including those under the European Union Restriction of the Use of Certain Hazardous Substances Directive (RoHS), Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), the Dodd-Frank Wall Street Reform and Consumer Protection Act (covering Conflict Minerals), and the Consumer Product Safety Improvement Act, the implementation of additional content-specific standards, discovery of unknown conditions, and claims for damages to property, persons or natural resources resulting from plant emissions or products, could also result in additional costs or liabilities.

Refer to Note 10, Commitments and Contingencies, to the accompanying consolidated financial statements for discussion of environmental investigation and remediation matters and Item 1A, "Risk Factors" for discussion of matters pertaining to other regulation.

International Operations

Our international operations are subject to a variety of risks, including currency fluctuations and devaluations, exchange controls, import/export restrictions, currency restrictions and changes in local economic conditions. While the impact of these risks is difficult to predict, any one or more of them could adversely affect our future operations. For more information about the noted risks, see Item 1A, "Risk Factors." For more information about our international operations, see Note 13, Segment Information, to the accompanying consolidated financial statements.

ITEM 1A. RISK FACTORS

The following are certain risk factors that could affect our business, results of operations, financial position or cash flows. Although the risks are organized by headings and each risk is described separately, many of the risks are interrelated. These risk factors should be considered along with the forward-looking statements contained in this Annual Report on Form 10-K because these factors could cause our actual results or financial condition to differ materially from those projected in forward-looking statements. The following discussion is not an all-inclusive listing of risks, although we believe these are the more material risks that we face. If any of the following occur, our business, results of operations, financial position or cash flows could be adversely affected.

Global Operating Risks

Our operations have in the past been and could in the future be adversely affected by various risks inherent in conducting operations worldwide.

We conduct a substantial portion of our business outside the U.S., with approximately 61% of our sales outside the U.S. We also have many facilities located outside the U.S., as detailed in Item 2, “Properties.” Accordingly, our business is subject to risks related to the differing legal, political, social and regulatory requirements, and economic conditions of many jurisdictions. Risks inherent in international operations include, but are not limited to, the following:

•changes in local government regulations and policies including, but not limited to, duty or tariff restrictions, foreign currency exchange controls or monetary policy, repatriation of earnings, expropriation of property, investment limitations and tax policies;

•political and economic instability and disruptions, including labor unrest, withdrawal or renegotiation of trade agreements, natural disasters, major public health issues, pandemics, civil strife, acts of war, insurrection and terrorism;

•supply chain disruptions;

•compliance with international trade laws and regulations, including tariffs, export control and economic sanctions, and other trade barriers;

•legislation that regulates the use of chemicals;

•disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations, including the Foreign Corrupt Practices Act (FCPA) and the UK Bribery Act;

•difficulties in staffing and managing multi-national operations;

•limitations on our ability to enforce legal rights and remedies;

•reduced protection of intellectual property rights;

•other risks arising out of foreign sovereignty over the areas where our operations are conducted; and

•increasingly complex laws and regulations concerning privacy and data security, including, but not limited to, the European Union's General Data Protection Regulation.

We could be adversely affected by violations of the FCPA, UK Bribery Act and similar worldwide anti-bribery laws, as well as export controls and economic sanction laws. As a global company, we operate in many parts of the world that have experienced governmental corruption. While we have no basis to believe such actions are occurring, if we are found to be liable for FCPA, UK Bribery Act, export control or sanction violations, we could suffer from criminal or civil penalties or other sanctions, including loss of export privileges or authorization needed to conduct aspects of our international business, which could have a material adverse effect on our business. We have robust policies that require compliance with all laws and regulations and we strictly enforce those policies. However, it is always possible an employee's or agent's unlawful actions may avoid detection.

Any of these risks could have an adverse effect on our international operations by reducing demand for our products.

7 AVIENT CORPORATION

Changes to foreign trade policy, including new or increased tariffs and changing import/export regulations, could adversely affect our operating results, and the impacts could be material.

Changes in foreign trade policy, regulatory or economic conditions or in laws governing international trade could materially adversely affect our business. The U.S. has instituted certain changes, and may propose additional changes, in trade policies that include the negotiation or termination of trade agreements, the imposition of higher tariffs on goods exported from the U.S. or imported into the U.S., and other government regulations affecting trade between the U.S. and other countries (such as Canada, Mexico, China, and the European Union) where we conduct our business. Global trade disruption or significant introduction of trade barriers, together with any future downturns in the global economy, could further materially and adversely affect our financial performance.

As a result of policy changes and government proposals, there may be greater restrictions and economic disincentives on international trade. 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 tariffs and trade sanctions. Such changes have the potential to adversely impact the global economy, our industry and the global demand for our products, and as a result, could have a negative impact on our business, financial condition and results of operations.

Business Risks

Demand for and supply of our products and services have in the past been, and may in the future be, adversely affected by several factors, some of which we cannot predict or control.

Several factors have in the past and may in the future affect the demand for and supply of of products and services, including:

•economic downturns, inflation or other uncertainty or volatility in the significant end markets that we serve;

•product obsolescence or technological changes that unfavorably alter the value/cost proposition of our products and services;

•competition from existing and unforeseen polymer and non-polymer based products;

•declines in general economic conditions or reductions in industrial production growth rates, both domestically and globally, which could impact customer confidence and demand, and our customers’ ability to pay amounts owed to us;

•changes in environmental regulations that limit our ability to purchase materials or sell our products and services in specific markets;

•changes in demand for, and laws and regulations regarding, plastic materials; and

•inability to obtain raw materials or supply products to customers due to factors such as supplier work stoppages or insolvency, supply shortages, plant outages or regulatory changes that may limit or prohibit overland transportation of certain hazardous materials and exogenous factors, like severe weather.

If any of these events occur in the future, the demand for and supply of our products and services could suffer and potentially lead to asset impairment or otherwise adversely affect our results.

Our manufacturing operations are subject to hazards and other risks associated with specialty formulation and the related storage and transportation of raw materials, products and waste.

The occurrence of an operating problem at our facilities may have a material adverse effect on the productivity and profitability of a particular manufacturing facility, or on our operations as a whole, during and after the period of these operating difficulties. Operating problems may cause personal injury and/or loss of life, customer attrition and severe damage to or destruction of property and equipment and environmental damage. Our property and casualty insurance, which we believe are of the types and in the amounts that are customary for the industry, may not fully insure us against all potential hazards that are incident to our business or otherwise could occur.

Our operations on, and ownership of, real property are subject to environmental, health and safety laws and regulations at the national, state and local governmental levels (including, but not limited to, the Regulation, Evaluation, Authorization, and Restriction of Chemicals (REACH), the Classification, Labeling, and Packaging Regulation (CLP), Restriction of Hazardous Substances (RoHS) and the Consumer Product Safety Improvement Act of 2008). The nature of our business exposes us to compliance costs and risks of liability under these laws and regulations due to the production, storage, transportation, recycling or disposal and/or sale of materials that can cause contamination and other harm to the environment or personal injury if they are improperly handled and released. Environmental compliance requirements imposed on us and our vendors may significantly increase the costs of these activities involving raw materials, energy, finished products and wastes. We may incur substantial costs, including fines, criminal or civil sanctions, damages, and remediation costs, or experience interruptions in our operations for violations of these laws.

Our accruals for such costs and associated liabilities are subject to changes in estimates on which the accruals are based. For example, any amounts accrued for environmental matters reflect the best information available and our assumptions about remediation requirements at the applicable site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites. Changes in estimates on which accruals are based, unanticipated government actions, or changes in health, safety, environmental or chemical control regulations could result in higher costs.

Electricity, fuel, logistics and raw material availability and costs have in the past and could in the future cause volatility in our results.

The cost of our electricity, fuel, logistics and raw materials may not correlate with changes in the prices we receive for our products, either in the direction of the price change or in absolute magnitude. Electricity and raw materials costs represent a substantial part of our manufacturing costs. We source certain strategic raw materials that may be difficult to replace or for our customers to requalify, which could result in the need to accept price increases. Most of the raw materials we use are commodities and the price of each can fluctuate widely for a variety of reasons, including changes in availability because of major capacity additions or reductions or significant facility operating problems. Other external factors beyond our control, including, but not limited to, trade barriers due to geopolitical tensions, can also cause fluctuations in raw materials prices, which could negatively impact demand for our products and cause volatility in our results.

Increased competition can negatively impact sales, earnings and cash flow performance.

We encounter competition in price, payment terms, delivery, service, performance, product innovation, product recognition and quality, depending on the product involved. Avient's operating results depend, in part, on continued successful research, development, and marketing of new products, and some of such efforts may not come to fruition or may be delayed.

We expect that our competitors will continue to develop and introduce new and enhanced products, which could cause a decline in the market acceptance of our products. In addition, our competitors could cause a reduction in the selling prices of some of our products as a result of intensified price competition. Competitive pressures could also result in the loss of customers.

Cybersecurity breaches, global information systems security threats and computer crime pose a risk to our systems, networks and products, which could harm our business.

We depend on integrated information systems to conduct our business, including communicating with employees and customers, ordering and managing materials from suppliers, shipping products to customers, and analyzing and reporting results of operations. Avient's IT capabilities are delivered through a combination of internal and external services and service providers. In addition, some of our systems, tools and resources use, integrate, or will integrate some form of artificial intelligence (AI), which has the potential to result in bias, miscalculations, data errors, and intellectual property infringement, and introduces additional risk associated with unauthorized access to our intellectual property, data security events, and disruption to our business. Further, we store sensitive data, including proprietary business information, intellectual property and confidential employee or other personal data, on our servers and databases.

9 AVIENT CORPORATION

Cybersecurity breaches, global information systems security threats and more sophisticated and targeted computer crime, including from threat actors who are increasingly leveraging AI for cyberattacks, pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data and communications. We continue to update our infrastructure, security tools, employee training and processes to protect against security incidents, including both external and internal threats, and to prevent their recurrence; however, our systems, networks and products may nevertheless be vulnerable to advanced persistent threats or other types of system failures. Depending on their nature and scope, such threats and system failures could lead to the compromising of confidential information and communications, improper use of our systems and networks, manipulation and destruction of data, defective products, production downtimes and operational disruptions, which in turn could cause customers to cancel orders or otherwise adversely affect our reputation, competitiveness and results of operations. We have experienced targeted and non-targeted cybersecurity attacks in the past and we could experience similar incidents in the future. To date, no cybersecurity incident or attack has had a material impact on our business or consolidated financial statements.

We are currently involved in various legal proceedings, and may be subject to future claims or other liability that could negatively impact our business and results of operations.

From time to time, we are involved in various legal proceedings or in commercial disputes and other legal and regulatory proceedings related to our business. Additionally, our development, manufacture and sale of specialty materials, including those sold to medical, automotive, consumer packaging, and construction end markets, involves risk of exposure to product liability claims, warranty claims, product recalls and related adverse publicity. While management establishes reserves based on assessments of the contingencies related to legal claims asserted against the Company, subsequent developments may affect such assessments and our estimates of the loss contingency and require payments in excess of the Company's reserves. An adverse judgment or significant product liability, warranty, or recall action could result in substantial expenditures, affect consumer confidence in our products and divert management's attention from other matters. While we maintain product liability insurance, insurance coverage may not be adequate.

Failure to develop new products and protect our intellectual property could negatively impact our future performance and growth.

Innovation and product development are foundational to our strategy and important to our future growth. Failure to create or acquire new technologies and new products could negatively impact our ability to deliver strong financial results. We may face challenges in customer qualification and adoption of new technologies, and failure of our products to work as predicted could lead to liability and damage to customer relationships and our reputation. We continually apply for and obtain U.S. and foreign patents to protect the results of our research and development efforts. Failure to protect our intellectual property could negatively affect our future performance and growth.

We are subject to risks associated with climate change and climate change legislation, regulation and international agreements.

Carbon emissions have become the subject of state and local, regional, national, and international attention. Concerns about climate change have resulted and may continue to result in the imposition of additional regulations or restrictions to which we may become subject. These regulatory developments related to climate change and climate disclosure and diligence, including the Corporate Sustainability Reporting Directive, could increase our operating and compliance costs, thereby impacting our business and consolidated financial statements.

From time to time, we establish strategies and expectations related to climate change and other environmental matters. Our ability to achieve any such strategies or expectations is subject to numerous factors and conditions, many of which are outside of our control. Examples of such factors include, but are not limited to, evolving legal, regulatory, and other standards, processes, and assumptions, the pace of scientific and technological developments, increased costs, the availability of requisite financing, and changes in carbon markets. Failures or delays (whether actual or perceived) in achieving our strategies or expectations related to climate change and other environmental matters could adversely affect our business, operations, and reputation, and increase risk of litigation.

Capital and Credit Risks

Fluctuation of foreign currency exchange rates may adversely impact our financial results.

We conduct business in various regions throughout the world and are therefore exposed to fluctuations in foreign currency exchange rates in relation to the U.S. dollar. Any significant change in the value of the currencies of the countries in which we do business against the U.S. dollar, whether precipitated by governmental monetary policy or otherwise, could affect our ability to sell products competitively and control our cost structure, which could have a material adverse effect on our business, financial condition and results of operations. Further, because our Consolidated Financial Statements are presented in U.S. dollars, increases or decreases in the value of the U.S. dollar relative to other currencies in which we conduct business have in the past and could in the future adversely impact our financial results. For additional detail related to this risk, see Item 7A, "Quantitative and Qualitative Disclosures About Market Risk."

Disruptions in the global credit, financial and/or currency markets could limit our access to credit or otherwise harm our financial results, which could have a material adverse impact on our business.

Global credit and financial markets experience volatility, including volatility in security prices, liquidity and credit availability, declining valuations of certain investments and significant changes in the capital and organizational structures of certain financial institutions. Market conditions may limit our ability to access the capital necessary to grow and maintain our business. Accordingly, we may be forced to delay raising capital, issue debt with shorter tenors than we prefer or pay unattractive interest rates, which could increase our interest expense, decrease our profitability and significantly reduce our financial flexibility.

The agreements governing our debt, including our revolving credit facility, term loan and other debt instruments, contain various covenants that limit our ability to take certain actions and in certain circumstances require us to meet financial maintenance tests, failure to comply with which could have a material adverse effect on us.

The agreements governing our senior secured revolving credit facility and our senior secured term loan, and the indentures and credit agreements governing our other debt, contain a number of customary restrictive covenants that, among other things, limit our ability to: sell or otherwise transfer assets, including in a spin-off, incur additional debt or liens, consolidate or merge with any entity or transfer or sell all or substantially all of our assets, pay dividends or make certain other restricted payments, make investments, enter into transactions with affiliates, create dividend or other payment restrictions with respect to subsidiaries, make capital investments and alter the business we conduct.

In addition, depending on our level of borrowing, our revolving credit facility requires us to comply under certain circumstances with specific financial tests, under which we are required to achieve certain or specific financial and operating results. Our ability to comply with these provisions may be affected by events beyond our control. A breach of any of these covenants would result in a default under such agreements and instruments, which in certain circumstances could be a default under all of these agreements and instruments. In the event of any default, our lenders could elect to declare all amounts borrowed under the agreements, together with accrued interest thereon, to be due and payable. In such event, we cannot assure that we would have sufficient assets to pay debt then outstanding under the agreements governing our debt.

Furthermore, certain of these agreements condition our ability to obtain additional borrowing capacity, engage in certain transactions or take certain other actions, on our achievement of certain or specific financial and operating results, although our failure to achieve such results would not result in a default under such agreements. Any future refinancing of our senior secured revolving credit facility or other debt may contain similar restrictive covenants.

Our ability to service long-term indebtedness requires cash.

Our ability to pay interest on our debt and to satisfy our other debt obligations depends in part upon our future financial and operating performance and that of our subsidiaries, and upon our ability to renew or refinance borrowings. Prevailing economic conditions and financial, business, competitive, legislative, regulatory and other factors, many of which are beyond our control, affect our ability to make these payments. While we believe that cash flow from our current level of operations, available cash and available borrowings under our revolving credit facility provide adequate sources of liquidity, a significant drop in operating cash flow resulting from economic conditions, competition or other uncertainties beyond our control could create the need for alternative sources of liquidity. If we are unable to generate sufficient cash flow to meet our debt service obligations, we will have to pursue one or more alternatives, such as reducing or delaying capital or other expenditures, refinancing debt, selling assets, or raising equity capital.

11 AVIENT CORPORATION

We have a significant amount of goodwill, and any future goodwill impairment charges could adversely impact our results of operations.

As of December 31, 2025, we had goodwill of $1,757.6 million. The future occurrence of a potential indicator of impairment, such as a significant adverse change in business climate, an adverse action or assessment by a regulator, unanticipated competition, a material negative change in relationships with customers, strategic decisions made in response to economic or competitive conditions could result in goodwill impairment charges, which could adversely impact our results of operations. For additional information on the results of our annual impairment testing, see Note 2, Goodwill and Intangible Assets, to the accompanying consolidated financial statements and “Critical Accounting Policies and Estimates” included in Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Avient may be subject to risks relating to changes in tax rates, changes in global tax laws and regulations, or exposure to additional income tax liabilities.

Avient is subject to income taxes in many jurisdictions around the world. Income tax liabilities are subject to the allocation of income among various tax jurisdictions. Our effective tax rate could be affected materially by changes in the mix among earnings in countries with differing statutory tax rates, changes in the valuation allowance of deferred tax assets, or changes in tax legislation, regulations, and policies. The amount of income taxes paid is subject to ongoing audits and litigation by tax authorities in the countries in which we operate. If these audits and/or litigation result in assessments different from amounts reserved, future financial results may include material unfavorable adjustments to our tax liabilities and cash taxes.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

We have a global cybersecurity program designed to identify, protect, detect, respond to and recover from cybersecurity risks and threats. We regularly assess risks from cybersecurity and technology threats and monitor our information systems for potential vulnerabilities. We use a widely-adopted risk quantification model to identify, measure and prioritize cybersecurity and technology risks and develop related security controls and safeguards. We conduct regular reviews and tests of our cybersecurity program, and monitor the risks associated with third party service providers. Internal audit reviews, penetration and vulnerability tests and other exercises are used to evaluate the effectiveness of our cybersecurity program and improve our security measures and planning. Additionally, organizational risks, including those associated with cybersecurity, are assessed regularly as part of Avient's Enterprise Risk Management program.

Cybersecurity education is a priority for our employees and business partners. Employees complete cybersecurity training to help identify and respond to potential cybersecurity risks and reinforce safe behaviors. We also impose security requirements upon our third-party services and software providers, including: maintaining an effective security management program; abiding by information handling and asset management requirements; and notifying us in the event of any known or suspected cyber incident; however, we rely on such third parties to implement security programs commensurate with their risk, and their efforts may not be successful.

We have experienced targeted and non-targeted cybersecurity attacks and incidents in the past and we could in the future experience similar attacks. To date, no cybersecurity incident or attack, or any risk from cybersecurity threats, has materially affected or has been determined to be reasonably likely to materially affect the Company or our business strategy, results of operations, or financial condition.

Governance

Our Chief Information Security Officer (CISO), who reports to our Chief Information Officer (CIO), is generally responsible for management of cybersecurity risk and the protection and defense of our networks and systems.

Avient's CISO has more than two decades of experience in information security across the pharmaceutical, medical device, and insurance sectors. This background includes responsibility for global functions such as data protection, insider risk management, threat detection and response, incident handling, vulnerability management, penetration testing, cloud security operations, and security engineering. The CISO's prior roles include the development and execution of information protection programs, management of third-party security and audit activities, and oversight of compliance initiatives aligned with frameworks and regulatory requirements including the National Institute of Standards and Technology, the International Organization for Standardization 27001, the Sarbanes-Oxley Act, and the Global Data Protection Regulation. The CISO holds professional certifications including Certified Information Systems Auditor (CISA), Certified Information Security Manager (CISM), and Certified Information Systems Security Professional (CISSP).

Our CISO is informed about and monitors prevention, detection, mitigation, and remediation efforts through regular communication and reporting from professionals on the information security team, and through the use of technological tools and software and results from third-party audits. Our CISO has a clear escalation path to senior management for cyber-related events.

Our CISO manages a team of cybersecurity professionals with broad experience and expertise, including in cybersecurity threat assessments and detection, mitigation technologies, cybersecurity training, incident response, cyber forensics, insider threats and regulatory compliance. Our cybersecurity teams hold relevant certifications, including, but not limited to: CISA, CISM, CISSP, Certified in Risk and Information Systems Control, Factor Analysis for Information Risk (FAIR) Analyst, Security Systems Certified Practitioner (SSCP) or Certified Federal Information Security Management Act Compliance Practitioner. We also supplement our cybersecurity program with third-party experts, who provide assessments of our program, testing of our environment, monitoring support, as well as insights into evolving trends in this space.

The Board oversees our annual enterprise risk assessment, where we assess key risks within the company, including security and technology risks and cybersecurity threats. The Audit Committee of the Board has been delegated specific risk oversight responsibilities related to cybersecurity and data protection. The Audit Committee receives regular updates from the CIO or CISO, and, as applicable, the internal audit team, regarding the Company's material risks from cybersecurity threats, cybersecurity defense and detection capabilities, incident response plans and employee training activities.

Further, Avient has a Cyber and Data Incident Response Team (CDIRT), which is a cross-functional group established to provide a quick, effective and orderly response to cyber and data related events. The CDIRT's mission is to prevent a material loss of profits, public confidence, or information assets by providing an immediate, effective, and skillful response to any unexpected event in which there is an unauthorized release or access of sensitive information.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is designed to provide information that is supplemental to, and should be read together with, our consolidated financial statements and the accompanying notes contained in this Annual Report on Form 10-K. Information in this Item 7 is intended to assist the reader in obtaining an understanding of our consolidated financial statements, the changes in certain key items in those financial statements from year to year, the primary factors that accounted for those changes, and any known trends or uncertainties that we are aware of that may have a material effect on our future performance, as well as how certain accounting principles affect our consolidated financial statements. Unless otherwise noted, the discussion that follows includes a comparison of our results of operations, liquidity and capital resources, and cash flows for fiscal years 2025 and 2024.

Our Business

We are an innovator of materials solutions to help our customers succeed, while enabling a sustainable world. Our products include specialty engineered materials, performance fibers, advanced composites, and color and additive solutions. We are also a highly specialized developer and manufacturer of performance enhancing additives, liquid colorants and silicone colorants. Headquartered in Avon Lake, Ohio, with 2025 sales of $3.3 billion, we have manufacturing and warehouses around the globe, with 61% of our sales to customers outside the United States. We provide value to our customers through our ability to link our knowledge of polymers and materials science with our manufacturing and supply chain capabilities to provide value-added solutions to designers, assemblers and processors of materials.

Strategy and Key Trends

In 2024, we unveiled Avient's new strategic direction guided by our purpose: to be an innovator of materials solutions to help our customers succeed, while enabling a sustainable world. We seek to achieve this with a two-pronged strategic approach: 1) building new platforms of scale, to play bigger and bolder in high-growth markets, and 2) catalyzing our core business, to maximize the impact of our existing portfolio. We have identified growth vectors — specific markets and applications targeted for above-market growth — in both accelerating markets and in our core business, by intersecting secular trends with our technologies.

We seek to operationalize our strategy using four strategic drivers: Portfolio Prioritization; Amplify Innovation; Digital for Operational Excellence and Growth; and Leadership, Talent, and Culture for the Avient of the Future. Our strategy builds upon Avient's foundational strengths refined over our history: unwavering customer focus; global reach with a local touch; diverse technology portfolio; commercial excellence; financial rigor and prudence; and a culture of safety and sustainability. The safety and health of our employees remain top priorities, and our ultimate goal is to operate injury-free.

In 2025, we made significant progress implementing our new strategy. Our growth vector sales are outpacing the rest of the Company, with defense and healthcare leading the way. Internal R&D collaboration has increased, resulting in technology sharing across businesses and geographies. We have bolstered digital capabilities with a focus on pilot projects designed to improve speed and efficiency. We continued to foster the culture needed to execute our strategy, and to build our talent pipeline by promoting leaders from within while bringing in external expertise as needed.

Sales

Sales increased $19.8 million, or 0.6%, in 2025 compared to 2024. Favorable foreign currency impacts were 0.9%, while sales, excluding the impacts of foreign exchange, decreased 0.3%. The sales decline was primarily within the consumer, industrial and energy end markets, partially offset by sales increases in the healthcare, defense and telecommunications end markets.

Gross Margin

Gross margin decreased to 31.2% from 32.6% in 2025 compared to 2024, primarily driven by higher restructuring charges of $22.2 million and higher operating costs, which included planned maintenance in the second quarter of 2025. Further, in 2024, Avient recognized a gain from insurance recoveries associated with previously incurred environmental remediation costs of $34.7 million as compared to a gain of $2.0 million in 2025. This was partially offset by lower environmental remediation charges of $11.6 million.

Selling and administrative expense

These costs include selling, technology, administrative functions, amortization of intangible assets, corporate and general expenses. Selling and administrative expense in 2025 increased $84.7 million compared to 2024, primarily driven by an impairment charge of $71.6 million associated with the Company's decision to cease development of the cloud-based enterprise resource planning system, S/4HANA, charges of $14.7 million associated with unpaid contractual obligations for hosting fees, and higher restructuring charges of $21.7 million. These charges were partially offset by productivity initiatives and lower incentive compensation cost.

Interest expense, net

Interest expense, net decreased $7.0 million in 2025 as compared to 2024, primarily driven by the benefit of reduced interest rates resulting from previous refinancing activity, in addition to prepayments totaling $150.0 million made on our senior secured term loan throughout 2025.

19 AVIENT CORPORATION

Other income, net

Other income, net increased $5.7 million in 2025 as compared to 2024, primarily associated to a $5.4 million increase in mark-to-market income associated with pension and post-retirement plans.

Income taxes

The 2025 consolidated effective tax rate was 25.2% compared to 24.1% in 2024. The higher tax rate was primarily attributable to higher Global Intangible Low-tax Income (GILTI) and Subpart F income and increases in valuation allowances. These increases were partially offset by the tax effects of intercompany transactions, including statutory impairments and the intercompany sale of intellectual property. Refer to Note 11 - Income Taxes for further detail, including a rate reconciliation.

Segment Information

Operating income is the primary segment performance measure that is reported to our chief operating decision maker (CODM), which is the Company's chief executive officer. Our CODM utilizes this measure to determine appropriate resource allocations to our segments in the annual planning process and to periodically assess segment performance, primarily by evaluating actual results in comparison to the annual operating plan and forecast. Operating income at the segment level does not include corporate general and administrative expenses that are not allocated to segments, restructuring charges, share-based compensation costs, environmental remediation costs and associated recoveries, asset impairments, acquisition-related charges, mark-to-market adjustments on pension and other post-retirement obligations, and certain other items that are not included in the measure of segment profit or loss that is reported to and reviewed by our CODM. These costs are included in Corporate.

Avient has two reportable segments: (1) Color, Additives and Inks and (2) Specialty Engineered Materials. Our segments are further discussed in Note 13, Segment Information, to the accompanying consolidated financial statements.

Color, Additives and Inks

Sales decreased $12.3 million, or 0.6%, in 2025 compared to 2024. Favorable foreign currency impacts were 1.0%, while sales, excluding the impacts of foreign exchange, decreased 1.6%. The sales decrease was primarily within the consumer, building and construction, industrial and transportation end markets, partially offset by growth in the healthcare end market.

Operating income increased $5.1 million, or 1.7%, in 2025 compared to 2024. The increase was primarily driven by improved mix and cost savings from productivity and restructuring actions, in addition to lower incentive compensation cost.

Specialty Engineered Materials

Sales increased $34.5 million, or 2.9%, in 2025 compared to 2024. Favorable foreign currency impacts were 0.9%, while sales, excluding the impacts of foreign exchange, increased 2.0%. The sales increase was primarily within the healthcare, defense and telecommunications end markets, partially offset by declines in the industrial, consumer and energy end markets.

20 AVIENT CORPORATION

Operating income decreased by $3.6 million, or 2.2%, in 2025 compared to 2024. The increase in sales was more than offset by higher operating costs, including costs associated with planned maintenance in the second quarter of 2025, raw material inflation, and investments in the Company's growth vectors.

Corporate

Corporate costs increased $127.3 million in 2025 compared to 2024, primarily driven by an impairment charge of $71.6 million associated with the Company's decision to cease development of the cloud-based enterprise resource planning system, S/4HANA, charges of $14.7 million associated with unpaid contractual obligations for hosting fees, and higher restructuring costs of $43.9 million. Further, in 2024, Avient recognized a gain from insurance recoveries associated with previously incurred environmental remediation costs of $34.7 million as compared to a gain of $2.0 million in 2025. This was partially offset by lower environmental remediation charges of $11.6 million in 2025, lower incentive compensation cost, and benefits from productivity initiatives.

Liquidity and Capital Resources

Our objective is to finance our business through operating cash flow and an appropriate mix of debt and equity. By laddering the maturity structure, we avoid concentrations of debt maturities, reducing liquidity risk. We may from time to time seek to retire or purchase our outstanding debt with cash on hand and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. We may also seek to repurchase our outstanding common shares. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved have been and may continue to be material.

The following table summarizes our liquidity as of December 31, 2025:

(In millions)
Cash and cash equivalents	$	510.5
Revolving credit availability	490.3
Liquidity	$	1,000.8

As of December 31, 2025, 76% of the Company’s cash and cash equivalents resided outside the United States.

Based on current projections, we believe that we will be able to continue to manage and control working capital, discretionary spending and capital expenditures and that cash provided by operating activities, along with available borrowing capacity under our revolving credit facilities, will allow us to maintain adequate levels of available capital to fund our operations, meet debt service obligations, continue paying dividends, and pay down debt and/or opportunistically repurchase outstanding common shares for at least twelve months and the foreseeable future thereafter.

Expected sources of cash needed to satisfy cash requirements in 2026 include our cash on hand, cash from operations and available liquidity under our revolving credit facility, if necessary. Expected uses of cash in 2026 include interest payments, cash taxes, dividend payments, debt repayment, share repurchases, environmental remediation payments and capital expenditures. Capital expenditures are currently estimated to be approximately $140 million in 2026, primarily to support organic sales growth and other strategic investments.

Cash Flows

21 AVIENT CORPORATION

Operating Activities

Net cash provided by operating activities increased to $301.6 million in 2025, as compared to $256.8 million in 2024, driven primarily by insurance proceeds of $34.0 million for previously incurred losses at the Calvert City site, a $23.0 million reduction in pension, retirement benefits and deferred compensation plan obligations, primarily associated with 2024 benefit payments for executive retirements, and a $17.9 million decrease in environmental remediation payments. This was partially offset by higher incentive payments in 2025 associated with 2024 performance and increased working capital.

Investing Activities

Net cash used by investing activities during 2025 of $97.0 million primarily reflects the impact of capital expenditures of $106.6 million, which were partially offset by proceeds from plant closures of $12.9 million.

Financing Activities

Net cash used by financing activities of $257.1 million in 2025 primarily reflects repayment on long-term borrowings of $150.3 million and $98.8 million of dividends paid.

Total Debt

The following table summarizes debt as of December 31, 2025 and 2024.

(In millions)	2025		2024
Senior secured revolving credit facility	—		—
Senior secured term loan due 2029	559.0		705.2

Less short-term debt	0.5		7.7
Total long-term debt, net of current portion	$	1,922.6	$	2,059.3

On March 12, 2025, the Company refinanced its senior secured term loan by amending the credit agreement governing such term loan (the Term Loan Amendment). The Term Loan Amendment reduced the interest rate per annum by 25 basis points, which now is either (i) Adjusted Term SOFR (as defined in the Term Loan Amendment) plus 1.75%, or (ii) a Base Rate (as defined in the Term Loan Amendment) plus 0.75%. The maturity date and other terms and conditions are substantially the same as the terms and conditions under the credit agreement immediately prior to the Term Loan Amendment.

During 2025, the Company made voluntary prepayments of $150.0 million on its senior secured term loan, which were applied to the principal installments in direct order of maturity. These prepayments were made without penalty or premium.

On June 12, 2025, the Company entered into a revolving credit agreement (the Revolving Credit Agreement) with various financial institutions as lenders, and JPMorgan Chase Bank, N.A., as administrative agent, which replaced our previous credit agreement set to mature in 2026. The Revolving Credit Agreement provides for a senior secured revolving credit facility of up to $500.0 million, which may be increased by up to $250.0 million, subject to certain conditions. Loans under the Revolving Credit Agreement will mature on June 12, 2030. The Revolving Credit Agreement contains representations and warranties, affirmative covenants, negative covenants and events of default that are substantially similar to those contained in the Company's existing term loan credit agreement.

As of December 31, 2025 and 2024, we had no borrowings outstanding under our Revolving Credit Facility. As of December 31, 2025, remaining availability under our Revolving Credit Facility was $490.3 million.

As of December 31, 2025, we were in compliance with all customary financial and restrictive covenants pertaining to our debt. For additional information regarding our debt, please see Note 4, Financing Arrangements to the accompanying consolidated financial statements.

Letters of Credit

Our Revolving Credit Facility provides up to $50.0 million for the issuance of letters of credit, $9.7 million of which was used at December 31, 2025. These letters of credit are issued by the bank in favor of third parties and are mainly related to required insurance programs.

Material Cash Requirements

We have future obligations under various contracts relating to debt and interest payments, operating leases, pension and post-retirement benefit plans, purchase obligations and environmental remediation obligations. The following table summarizes our obligations as of December 31, 2025 that are expected to impact liquidity and cash flow in future periods. See Liquidity and Capital Resources for additional discussion of our ability to generate and access cash to meet requirements as well as plans for use of cash in both the short-term and long-term.

(1)Represents estimated contractual interest payments for all outstanding debt. Excludes cash receipts from cross-currency swaps as described in Note 14, Derivatives and Hedging.

(2)This represents estimates related to the funding obligations of our pension and other post retirement plans. These contributions are based on actuarial estimates of future assumed payments based upon retirement and payment patterns for a 10-year period. The estimates in the table may differ materially from actual future payments due to uncertainties regarding the assumptions involved in estimating future required contributions to our pension and non-pension post retirement benefit plans, including (i) interest rate levels (ii) the amount and timing of asset returns and (iii) what, if any, changes may occur in pension funding legislation.

(3)Purchase obligations are primarily comprised of service agreements related to telecommunication, information technology, utilities and other manufacturing plant services and certain capital commitments.

Critical Accounting Policies and Estimates

Significant accounting policies are described more fully in Note 1, Description of Business and Summary of Significant Accounting Policies, to the accompanying consolidated financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires us to make estimates and assumptions about future events that affect the amounts reported in our consolidated financial statements and accompanying notes. We base our estimates on historical experience and assumptions that we believe are reasonable considering the related facts and circumstances. The application of these critical accounting policies involves the exercise of judgment and use of assumptions for future uncertainties. Accordingly, actual results could differ significantly from these estimates. We believe that the following discussion addresses our most critical accounting policies, which are those that are the most important to the portrayal of our financial condition and results of operations and require our most difficult, subjective and complex judgments.

Revenue Recognition

Sales are recognized when control of promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services, which is typically when products are shipped from our facilities. The majority of the Company’s sales agreements contain performance obligations satisfied at a point in time when control is transferred to the customer. Avient records reductions to sales for customer incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience along with annual sales projections. Rebate programs offered are typically credited to customers for achieving defined volume levels.

Environmental Liabilities

We are a party to a Consent Decree related to remedial actions at the former Goodrich Corporation Calvert City site and will incur environmental remediation costs related to this matter. We recognize an estimate of environmental liabilities on an undiscounted basis for probable future environmental expenditures. Any such provision is recognized using the Company's best estimate of the amount of loss incurred, or at the lower end of an estimated range, when a single best estimate is not determinable. In some cases, the Company recovers a portion of the costs relating to these obligations from insurers or other third parties, and the recovery is recognized when realization of the proceeds is deemed as probable.

23 AVIENT CORPORATION

Environmental liabilities represents our best estimate of the remaining probable costs based upon information and technology currently available. Depending upon the results of future testing, the ultimate remediation alternatives undertaken, changes in regulations, new information, newly discovered conditions and other factors, it is reasonably possible that we could incur additional costs in excess of the amount accrued. However, such additional costs, if any, cannot currently be estimated. Our estimate of this liability may be revised as new regulations or technologies are developed or additional information is obtained. As we progress through remedial design and remedial action related to the Goodrich Corporation Calvert City site, additional information will become available that may require an adjustment to our existing accrual. Adjustments have been material to our financial statements in the past and it is reasonably possible that they could be in the future.

Additional information related to the accounting for environmental liabilities is found in Note 10, Commitments and Contingencies.

Pension Benefit Plans

The measurement of liabilities related to pension benefit plans is based on assumptions related to future events including interest rates, return on plan assets, and mortality assumptions. We immediately recognize actuarial gains and losses in our operating results in the year in which the gains or losses occur.

Asset returns and interest rates significantly affect the value of assets and liabilities related to our pension plans and therefore the funded status of our plans. It is difficult to predict these factors due to the volatility of market conditions. To develop our discount rate, we consider the yields of high-quality corporate bonds with maturities that correspond to the timing of our benefit obligations, referred to as the bond matching approach. To develop our expected long-term return on plan assets, we consider forward looking long-term asset returns and the expected investment portfolio mix of plan assets. Life expectancy is another significant assumption that impacts our pension obligation, which is based on mortality data and improvement scales issued by the Society of Actuaries.

Additional information related to the accounting for pension and other post-retirement benefits is found in Note 9, Employee Benefit Plans.

Income Taxes

We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. In addition, deferred tax assets are also recorded with respect to net operating losses and other tax attribute carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when realization of the benefit of deferred tax assets is not deemed to be more likely than not. The utilization of certain deferred tax assets is dependent on the amount and timing of taxable income that we will ultimately generate in the future and other factors, such as changes in tax laws.

We recognize net tax benefits under the recognition and measurement criteria, which prescribes requirements and other guidance for financial statement recognition and measurement of positions taken or expected to be taken on tax returns. We recognize an income tax benefit from an uncertain tax position only if it is more likely than not that the benefit would be sustained upon examination by taxing authorities, based on the technical merits of the position. The Company evaluates and adjusts the amount of unrecognized income tax benefits based on changes in law, facts and circumstances. We record interest and penalties related to uncertain tax positions as a component of income tax expense. The ultimate resolution of unrecognized income tax benefits is often dependent upon uncontrollable factors such as the timing of finalizing resolutions of audit disputes through reaching settlement agreements, or changes in law.

Additional information related to the accounting for income taxes is found in Note 11, Income Taxes.

Goodwill

Goodwill is evaluated annually for impairment as of October 1 using either a quantitative or qualitative analysis. Goodwill is tested for impairment at the reporting unit level and is based on the net assets for each reporting unit, including goodwill and intangible assets. The Company’s reporting units are at a level below the Company’s reportable operating segments. Goodwill is assigned to each reporting unit, as this represents the lowest level that constitutes a business and is the level at which management regularly reviews the operating results.

24 AVIENT CORPORATION

Additionally, goodwill is evaluated for impairment whenever an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Events or circumstances that may result in an impairment review include changes in macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant entity-specific events, specific events affecting the reporting unit or sustained decrease in share price.

Quantitative analyses are performed by estimating the fair value for each reporting unit using a discounted cash flow model. These analyses include estimates of future cash flows, future growth rates, terminal value amounts, and the applicable weighted-average cost of capital used to discount estimated cash flows. The future cash flows are based on the Company's long-term strategic plan, and a terminal value is used to estimate the reporting unit's cash flows beyond the period covered by the strategic plan. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of judgments, including judgments about appropriate discount rates, revenue growth, operating margins, and long-term growth rates.

A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data, and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative analysis performed for each reporting unit.

In 2025, the annual goodwill impairment test was performed using a qualitative analysis with the exception of certain reporting units where management elected to bypass the qualitative analysis and perform a quantitative analysis. Based on the analyses performed in 2025, the fair value of the Company's reporting units continues to exceed their respective carrying amounts, and accordingly, no impairment charges were recognized.

Indefinite-lived Trade Names

Indefinite-lived trade names are evaluated annually for impairment as of October 1 using either a quantitative or qualitative analysis to determine whether their fair values exceed their respective carrying amounts. Additionally, indefinite-lived trade names are evaluated for impairment whenever an event occurs or circumstances change that would indicate that it is more likely than not that the asset is impaired. Events or circumstances that may result in an impairment review include changes in industry and market considerations, cost factors, financial performance, and other relevant entity-specific events that could affect inputs used to determine the respective fair values of the indefinite-lived trade names.

Quantitative analyses are performed by estimating the fair value for each indefinite-lived trade name using a royalty relief methodology. These analyses include estimates of future cash flows that are based on the Company's long-term strategic plan and the applicable weighted-average cost of capital used to discount estimated cash flows. The primary inputs to these estimates require the exercise of judgments, including judgments about appropriate discount rates, revenue growth, royalty rates, and long-term growth rates.

A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales, discount rates, industry data, and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative analysis performed for each indefinite-lived trade name.

In 2025, the indefinite-lived trade names impairment tests were performed using a qualitative approach. Based on this qualitative assessment, management concluded that the fair values of the Company's indefinite-lived trade names continued to exceed their carrying values, and accordingly, no impairment charges were recognized.

For additional information about goodwill and intangible assets see Note 2, Goodwill and Intangible Assets.

Recent and Future Adoption of Accounting Standards

Information regarding recent and future adoption of accounting standards can be found in Note 1, Description of Business and Summary of Significant Accounting Policies, to the accompanying consolidated financial statements and is incorporated by reference herein.

25 AVIENT CORPORATION

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks as part of our ongoing business operations, including risks from changes in interest rates on debt obligations and foreign currency exchange rates that could impact our financial condition, results of operations and cash flows. We manage our exposure to these and other market risks through regular operating and financing activities, including the use of derivative financial instruments. We intend to use these derivative financial instruments as risk management tools and not for speculative investment purposes.

Interest rate exposure — Interest on our Revolving Credit Facility and senior secured term loan is based upon a Base Rate or Adjusted Term SOFR, plus a margin. There would be no material impact on our interest expense or cash flows from either a 100 basis point increase or decrease in market rates of interest on our outstanding variable rate debt as of December 31, 2025.

Foreign currency exposure — We have exposure from both third-party and intercompany transactions that are denominated in various foreign currencies and are subject to foreign exchange rate movements. To mitigate this risk, we may enter into foreign exchange forward contracts and derivative instruments. Gains and losses on these contracts generally offset gains and losses on the assets and liabilities being hedged.

We also face translation risks related to the changes in foreign currency exchange rates. Amounts invested in our foreign operations are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. The resulting translation adjustments are recorded as a component of Accumulated other comprehensive income (loss) in the Shareholders’ equity section of the accompanying Consolidated Balance Sheets. To mitigate a portion of this risk, we may enter into cross-currency swaps. Gains and losses on these contracts generally offset gains and losses on the Euro denominated investment in our foreign entities. Net sales and expenses in our foreign operations’ foreign currencies are translated into varying amounts of U.S. dollars depending upon whether the U.S. dollar weakens or strengthens against other currencies. Therefore, changes in exchange rates may either positively or negatively affect our net sales and expenses from foreign operations as expressed in U.S. dollars.

MANAGEMENT’S REPORT

The management of Avient Corporation is responsible for preparing the consolidated financial statements and disclosures included in this Annual Report on Form 10-K. The consolidated financial statements and disclosures included in this Annual Report fairly present in all material respects the consolidated financial position, results of operations, shareholders’ equity and cash flows of Avient Corporation as of and for the year ended December 31, 2025.

Management is responsible for establishing and maintaining disclosure controls and procedures designed to ensure that the information required to be disclosed by the Company is captured and reported in a timely manner. Management has evaluated the design and operation of the Company’s disclosure controls and procedures at December 31, 2025 and found them to be effective.

Management is also responsible for establishing and maintaining a system of internal control over financial reporting that is 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. Internal control over financial reporting includes policies and procedures that provide reasonable assurance that: Avient Corporation’s accounting records accurately and fairly reflect the transactions and dispositions of the assets of the Company; unauthorized or improper acquisition, use or disposal of Company assets will be prevented or timely detected; the Company’s transactions are properly recorded and reported to permit the preparation of the Company’s consolidated financial statements in conformity with generally accepted accounting principles; and the Company’s receipts and expenditures are made only in accordance with authorizations of management and the Board of Directors of the Company.

Management has assessed the effectiveness of Avient’s internal control over financial reporting as of December 31, 2025 and has prepared Management’s Annual Report On Internal Control Over Financial Reporting contained on page 63 of this Annual Report, which concludes that as of December 31, 2025, Avient’s internal control over financial reporting was effective and that no material weaknesses were identified.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Avient Corporation

Opinion on Internal Control over Financial Reporting

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

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, cash flows and shareholders' equity for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 17, 2026, expressed an unqualified opinion thereon.

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 that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

To the Shareholders and the Board of Directors of Avient Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Avient Corporation (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, cash flows and shareholders' equity for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at 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 U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 17, 2026 expressed an unqualified opinion thereon.

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.

	Environmental Accrued Liabilities - Calvert City
Description of the Matter	As described in Note 10 to the consolidated financial statements, the environmental accrued liability as of December 31, 2025 is approximately $141.2 million and is comprised primarily of the cost estimate for the Calvert City location of $133.2 million. The Company records an accrual for probable future environmental remediation projects on an undiscounted basis which represents management’s best estimate of probable future costs based upon currently available information and technology and management’s view of the most likely remedy.
	Auditing the determination of the accrual involved a high degree of subjectivity as estimates underlying the determination of the accrual were based on assumptions unique to the affected site and subject to various laws and regulations governing the protection of the applicable environment. Actual costs incurred in future periods could differ from amounts estimated and future changes to environmental laws and regulations could change the extent of remediation work required, therefore the calculation is complicated due to uncertainty in determining the probable future costs and the extent of the remediation efforts.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process to estimate the Calvert City environmental-related accrual. For example, we tested controls over management’s review of the estimate and key assumptions, as well as monitoring for current year developments.
	With the assistance of our specialists, we tested the balance of the Calvert City environmental accrued liability and the disclosure of the expected costs to remediate. Our audit procedures included, among others, making inquiries of internal general counsel and obtaining legal letters from internal and external counsel. We also evaluated external communications including those from the U.S. Environmental Protection Agency (U.S. EPA) and cost estimates from management’s specialists and other third parties used in determining the environmental accrued liability. We tested the key assumptions used by management by comparing those assumptions to accepted industry practice and information included in the Record of Decision issued by the U.S. EPA, as applicable. We examined historical costs for recurring items and evaluated updated cost estimates for any current period changes. We searched publicly available information that might indicate facts contrary to the cost estimates and timeline used to determine the Calvert City accrual.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

We are an innovator of materials solutions to help our customers succeed, while enabling a sustainable world. Our products include specialty engineered materials, performance fibers, advanced composites, and color and additive solutions. We are also a highly specialized developer and manufacturer of performance enhancing additives, liquid colorants, and fluoropolymer and silicone colorants. Headquartered in Avon Lake, Ohio, we have employees at sales and manufacturing sites across North America, South America, Europe, the Middle East, Asia, and Africa. We provide value to our customers through our ability to link our knowledge of polymers and materials science with our manufacturing and supply chain to provide value added solutions to designers, assemblers and processors of materials. When used in these notes to the consolidated financial statements, the terms “we,” “us,” “our,” “Avient” and the “Company” mean Avient Corporation and its consolidated subsidiaries.

Our operations are reported in two reportable segments: Color, Additives and Inks, and Specialty Engineered Materials. See Note 13, Segment Information, for more information.

Accounting Standards Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated income tax disclosures on an annual basis, including information on the Company's effective tax rate reconciliation and income taxes paid. The Company adopted ASU 2023-09 on a prospective basis for the year ended December 31, 2025. The adoption of ASU 2023-09 impacted income tax disclosures within Note 11, Income Taxes.

Accounting Standards Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03). This accounting standard requires disaggregated income statement expense disclosures on an annual and interim basis, including inventory purchases, employee compensation, depreciation, and intangible asset amortization for each income statement line item that contains these expenses. The standard also requires disclosure of total selling expenses on an annual and interim basis, and the definition of those expenses disclosed annually. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied prospectively or retrospectively. The Company is evaluating the impact of ASU 2024-03. As the standard will only impact its disclosures, there will be no material impact to the consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (ASU 2025-05). This accounting standard provides a practical expedient allowing entities to assume that current conditions as of the balance sheet date remain unchanged over the remaining life of the asset when estimating expected credit losses. ASU 2025-05 is effective for annual reporting periods, including interim reporting periods within those annual periods, beginning after December 15, 2025, with early adoption permitted and should be applied prospectively. The Company is evaluating the impact of ASU 2025-05 and expects the standard will not have a material impact on the consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) Targeted Improvements to the Accounting for Internal-Use Software (ASU 2025-06). This accounting standard changes when software project costs should be capitalized by removing all references to development stages and requiring costs to be capitalized when (1) the Company authorizes and commits to funding the software project and (2) it is probable the software project will be completed. The standard also requires additional annual and interim disclosures, including the capitalized software balance and accumulated amortization. ASU 2025-06 is effective for annual reporting periods, including interim reporting periods within those annual periods, beginning after December 15, 2027, with early adoption permitted and may be applied prospectively, retrospectively, or using a modified prospective transition approach. The Company is evaluating the impact of ASU 2025-06 to the consolidated financial statements and related disclosures.

Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of Avient and its subsidiaries. All majority-owned affiliates over which we have control are consolidated. Transactions with related parties, including joint ventures, are in the ordinary course of business. Certain prior year amounts have been adjusted to conform to current year presentation.

Use of Estimates

Preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions in certain circumstances that affect amounts reported in the accompanying consolidated financial statements and notes. Actual results could differ from these estimates.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with a maturity of less than three months to be cash equivalents. Cash equivalents are stated at cost, which approximates fair value.

Allowance for Doubtful Accounts

We evaluate the collectability of receivables based on a combination of factors, each of which are adjusted if specific circumstances change. We reserve for amounts determined to be uncollectible based on a specific customer’s inability to meet its financial obligation to us, resulting from an assessment of current conditions and forecasted information, the credit risk of specific customers, economic conditions and historical experience. We also record a general reserve based on the age of receivables past due. In estimating the allowance, we take into consideration the existence of credit insurance.

Inventories

Raw materials and finished goods are carried at lower of cost or net realizable value using either the weighted average cost or the first-in, first-out (FIFO) method. We record reserves for inventory that is damaged, obsolete, excess and slow-moving to Cost of sales.

Long-lived Assets

Property, plant and equipment is carried at historical cost, net of depreciation and amortization that is computed using the straight-line method over the estimated useful lives of the assets, which generally ranges from 3 to 15 years for machinery and equipment and up to 40 years for buildings. We depreciate certain assets associated with closing manufacturing locations over a shortened life (through the cease-use date). We expense repair and maintenance costs as incurred. We capitalize replacements and improvements that increase the estimated useful life of an asset. We retain fully depreciated assets in property and accumulated depreciation accounts until we remove them from service.

We account for operating and finance leases under the provisions of FASB Accounting Standards Codification (ASC) Topic 842.

Finite-lived intangible assets, which consist primarily of customer relationships, patents and technology are amortized over their estimated useful lives. The useful lives range up to 25 years.

We assess the recoverability of long-lived assets when events or changes in circumstances indicate that we may not be able to recover the assets’ carrying amount. We measure the recoverability of assets to be held and used by a comparison of the carrying amount of the asset to the expected future undiscounted cash flows associated with the asset. We measure the amount of impairment of long-lived assets as the amount by which the carrying value of the asset exceeds the fair value of the asset, which is generally determined based on projected discounted future cash flows or appraised values.

Internal-Use Software and Cloud Computing Arrangements

We capitalize costs related to computer software obtained or developed for internal use. Software obtained for internal use has generally been enterprise-level business software that the Company customizes to meet its specific operational needs. Costs incurred in the application development phase are capitalized as Property, Net in the Company’s Consolidated Balance Sheets and are depreciated using the straight-line method over their estimated useful lives.

38 AVIENT CORPORATION

We also enter into certain cloud-based software hosting arrangements. Capitalizable cloud computing arrangement costs are generally consistent with those incurred during the application development stage for internal-use software, however, these costs are capitalized as Other assets in the Company's Consolidated Balance Sheets. As of December 31, 2025 and 2024, there was $5.8 million and $76.4 million capitalized within Other non-current assets, respectively. In the first quarter of 2025, the Company completed a review of its cloud-based enterprise resource planning system, S/4HANA, including updated project timelines, cost incurred to date, required internal resources and expected costs to complete the initial site implementations, and the evolution of options that could provide better returns for shareholders. As a result of this review, the Company determined it would cease the ongoing development of S/4HANA. As a result of this decision, in the first quarter of 2025, the Company recognized a non-cash, pre-tax impairment charge of $71.6 million associated with capitalized implementation costs. Refer to Note 3, Employee Separation and Restructuring Costs, for more information.

Goodwill and Indefinite Lived Intangible Assets

Goodwill is the excess of the purchase price paid over the fair value of the net assets of the acquired business. We assess goodwill for impairment on an annual basis or more frequently when events or changes in circumstance indicate that the asset may be impaired. Goodwill is tested for impairment at the reporting unit level. The Company's reporting units are at a level below the Company's reportable operating segments. Goodwill is allocated to the reporting units based on the estimated fair value at the date of acquisition. Our annual measurement date for testing impairment of goodwill assets is October 1.

The Company may perform a qualitative test to determine whether it is more likely than not the fair value of a reporting unit is less than its carrying amount in order to determine whether it is necessary to perform a quantitative goodwill impairment test. For our quantitative test, we use an income approach to estimate the fair value of our reporting units. The income approach uses a reporting unit’s projection of estimated operating results and cash flows that is discounted using a weighted-average cost of capital that is determined based on current market conditions. The projection uses management’s best estimates of economic and market conditions over the projected period, including sales growth rates, operating margins, capital expenditures, working capital, discount rates and terminal value growth rates. We validate our estimates of fair value under the income approach by considering the implied control premium and conclude whether the implied control premium is reasonable based on other recent market transactions.

In 2025, the annual goodwill impairment test was performed using a qualitative analysis with the exception of certain reporting units where management elected to bypass the qualitative analysis and perform a quantitative analysis. Based on the analyses performed in 2025, the fair value of the Company's reporting units continue to exceed their respective carrying amounts, and accordingly, no impairment charges were recognized.

Indefinite-lived intangible assets primarily consist of certain trade names. Indefinite-lived intangible assets are tested qualitatively or quantitatively for impairment at least annually as of October 1 to determine whether their fair values exceed their respective carrying amounts, unless events or changes in circumstance indicate that the asset may be impaired prior to the annual test. For our quantitative test, the implied fair value of indefinite-lived intangible assets is determined based on significant unobservable inputs. The fair value of the trade names is calculated using a “relief from royalty” methodology. This approach involves two steps: (1) estimating reasonable royalty rates for the trade name and (2) applying this royalty rate to a net sales stream and discounting the resulting cash flows to determine fair value using a weighted-average cost of capital that is determined based on current market conditions. This fair value is then compared with the carrying value of the trade name.

The Company performed its annual impairment testing of indefinite-lived intangible assets using a qualitative approach. Management assessed relevant trends and factors, including projected market outlook and growth rates, forecasted and actual sales performance, discount rates, and other qualitative considerations. Based on these assessments, management concluded that no quantitative analysis is required and the fair values of the Company's indefinite-lived intangible assets exceeded their carrying values, and accordingly, no impairment charges were recognized.

Litigation Reserves

We accrue for loss contingencies associated with outstanding litigation, claims and assessments for which management has determined it is probable that a loss contingency exists and the amount of loss can be reasonably estimated. We recognize expense associated with professional fees related to litigation claims and assessments as incurred. Refer to Note 10, Commitments and Contingencies, for further information.

Derivative Financial Instruments

All derivative financial instruments, such as foreign exchange contracts, are recognized in the financial statements and measured at fair value, regardless of the purpose or intent in holding them.

In the normal course of business, we are exposed to fluctuations in foreign currency exchange rates as well as variability in cash flows resulting from changes in contractually specified interest rates (e.g., SOFR). We have established policies and procedures that manage this exposure through the use of financial instruments. By policy, we do not enter into these instruments for trading purposes or speculation. We formally assess, designate and document, as a hedge of an underlying exposure, the qualifying derivative instrument that will be accounted for as an accounting hedge at inception. Additionally, we assess at inception whether the financial instruments used in the hedging transaction are highly effective at offsetting changes in either the fair values or cash flows of the underlying exposures. If highly effective, any subsequent test may be done qualitatively.

We have cross-currency swaps which are documented and designated as net investment hedges of our Euro denominated investment in foreign entities. We pay fixed-rate interest in Euros and receive fixed-rate interest in U.S. dollars related to our future obligations to exchange Euros for U.S. dollars. The interest receivable on the swaps is accrued each month for effective instruments designated as a hedge and is reflected within Interest expense, net within the Consolidated Statements of Income and the remaining change in the fair value of the derivatives is recorded as a component of Accumulated Other Comprehensive Income (Loss) (AOCI). From time to time, we may enter into certain foreign currency exchange forward contracts, which are not designated as hedges and are adjusted to fair value at each period end, with the resulting gains and losses recognized in the accompanying Consolidated Statements of Income immediately.

Refer to Note 14, Derivatives and Hedging, for more information.

Pension and Other Post-retirement Plans

We immediately recognize actuarial gains and losses in our operating results in the year in which the gains or losses occur. Refer to Note 9, Employee Benefit Plans, for more information.

Accumulated Other Comprehensive Income (Loss)

Changes in accumulated other comprehensive income (loss) in 2025, 2024 and 2023 were as follows:

Fair Value of Financial Instruments

The estimated fair values of financial instruments were principally based on market prices where such prices were available and, where unavailable, fair values were estimated based on market prices of similar instruments.

Foreign Currency Translation

Revenues and expenses are translated at average currency exchange rates during the related period. Assets and liabilities of foreign subsidiaries are translated using the exchange rate at the end of the reporting period. The resulting translation adjustments are recorded as accumulated other comprehensive income or loss. Gains and losses resulting from foreign currency transactions, including intercompany transactions that are not considered long-term investments, are included in Other income, net.

Revenue Recognition

We recognize revenue once control of the product is transferred to the customer, which typically occurs when products are shipped from our facilities.

Shipping and Handling Costs

Shipping and handling costs are included in Cost of sales.

Research and Development Expense

Research and development costs of $96.7 million in 2025, $98.7 million in 2024 and $90.3 million in 2023 are charged to expense as incurred.

Environmental Remediation Costs

We expense costs that are associated with managing hazardous substances and pollution in ongoing operations on a current basis. Costs associated with environmental contamination are accrued when it becomes probable that a liability has been incurred and our proportionate share of the cost can be reasonably estimated. Any such provision is recognized using the Company's best estimate of the amount of loss incurred, or at the lower end of an estimated range, when a single best estimate is not determinable. In some cases, the Company recovers a portion of the costs relating to these obligations from insurers or other third parties, and the recovery is recognized when realization of the proceeds is deemed as probable.

Share-Based Compensation

In accounting for share-based compensation, we estimate the fair value of share-based awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the accompanying Consolidated Statements of Income. As of December 31, 2025, we had one active share-based employee compensation plan, which is described more fully in Note 12, Share-Based Compensation.

Income Taxes

Deferred income tax liabilities and assets are determined based upon the differences between the financial reporting and tax basis of assets and liabilities and are measured using the tax rate and laws currently in effect. We evaluate our deferred income taxes to determine whether a valuation allowance should be established against the deferred tax assets or whether the valuation allowance should be reduced based on consideration of all available evidence, both positive and negative, using a “more likely than not” standard. See Note 11, Income Taxes, for additional detail.

Note 3 — EMPLOYEE SEPARATION AND RESTRUCTURING COSTS

Cloud-based Enterprise Resource Planning System Impairment and Other Related Charges

In the first quarter of 2025, the Company completed a review of its cloud-based enterprise resource planning system, S/4HANA, including updated project timelines, cost incurred to date, required internal resources and expected costs to complete the initial site implementations, and the evolution of options that could provide better returns for shareholders. As a result of this review, the Company determined it would cease the ongoing development of S/4HANA.

As a result of this decision, in the first quarter of 2025, the Company recognized a non-cash, pre-tax impairment charge of $71.6 million associated with capitalized implementation costs. The Company also recognized pre-tax charges of $14.7 million associated with unpaid contractual obligations for hosting fees. Further, the Company recognized charges of $2.8 million associated to severance actions resulting from the decision to cease development of S/4HANA. These charges are included in Selling and administrative expense within the Consolidated Statements of Income.

On March 12, 2025, the Company refinanced its senior secured term loan by amending the credit agreement governing such term loan (the Term Loan Amendment). The Term Loan Amendment reduced the interest rate per annum by 25 basis points, which now is either (i) Adjusted Term SOFR (as defined in the Term Loan Amendment) plus 1.75%, or (ii) a Base Rate (as defined in the Term Loan Amendment) plus 0.75%. The maturity date and other terms and conditions are substantially the same as the terms and conditions under the credit agreement immediately prior to the Term Loan Amendment.

During 2025, the Company made voluntary prepayments of $150.0 million on its senior secured term loan, which were applied to the principal installments in direct order of maturity. These prepayments were made without penalty or premium.

On June 12, 2025, the Company entered into a revolving credit agreement (the Revolving Credit Agreement) with various financial institutions as lenders, and JPMorgan Chase Bank, N.A., as administrative agent, which replaced our previous credit agreement set to mature in 2026. The Revolving Credit Agreement provides for a senior secured revolving credit facility of up to $500.0 million, which may be increased by up to $250.0 million, subject to certain conditions. Loans under the Revolving Credit Agreement will mature on June 12, 2030. The Revolving Credit Agreement contains representations and warranties, affirmative covenants, negative covenants and events of default that are substantially similar to those contained in the Company's existing term loan credit agreement.

As of December 31, 2025 and 2024, we had no borrowings outstanding under our Revolving Credit Facility. As of December 31, 2025, remaining availability under our Revolving Credit Facility was $490.3 million.

The agreements governing our Revolving Credit Facility and our senior secured term loan, and the indentures and credit agreements governing other debt contain a number of customary financial and restrictive covenants that, among other things, limit our ability to: sell or otherwise transfer assets, including in a spin-off, incur additional debt or liens, consolidate or merge with any entity or transfer or sell all or substantially all of our assets, pay dividends or make certain other restricted payments, make investments, enter into transactions with affiliates, create dividend or other payment restrictions with respect to subsidiaries, make capital investments and alter the business we conduct. As of December 31, 2025, we were in compliance with all covenants.

Included in Interest expense, net for the years ended December 31, 2025, 2024 and 2023 was interest income of $46.3 million, $50.1 million, and $49.8 million, respectively. Interest income includes the impact of cross-currency swaps, as described in Note 14, Derivatives and Hedging. Total interest paid on debt, net of the impact of hedging, was $97.6 million in 2025, $85.2 million in 2024 and $106.3 million in 2023.

Note 5 — LEASING ARRANGEMENTS

We lease certain manufacturing facilities, warehouse space, machinery and equipment, vehicles and information technology equipment under operating leases. The majority of our leases are operating leases. Finance leases are immaterial to our consolidated financial statements. Operating lease assets and obligations are reflected within Operating lease assets, net, Accrued expenses and other current liabilities, and Other non-current liabilities, respectively.

Lease expense for these leases is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the period those payments are incurred. The components of lease cost recognized within our Consolidated Statements of Income for the years ended December 31, 2025, 2024 and 2023 were as follows:

(In millions)	2025		2024		2023
Cost of sales	$	21.3	$	20.8	$	19.7
Selling and administrative expense	14.5		11.2		11.6
Total operating lease cost	$	35.8	$	32.0	$	31.4

We often have options to renew lease terms for buildings and other assets. The exercise of lease renewal options are generally at our sole discretion. In addition, certain lease arrangements may be terminated prior to their original expiration date at our discretion. We evaluate renewal and termination options at the lease commencement date to determine if we are reasonably certain to exercise the option on the basis of economic factors. The weighted average remaining lease term for our operating leases as of December 31, 2025 and 2024 was 5.1 years and 5.6 years, respectively. The non-cash net increase in operating lease liabilities was $10.0 million, $37.3 million and $18.1 million for the years ended December 31, 2025, 2024 and 2023, respectively.

The discount rate implicit within our leases is generally not determinable and, therefore, the Company determines the discount rate based on its incremental borrowing rate. The incremental borrowing rate for our leases is determined based on lease term and currency in which lease payments are made, adjusted for impacts of collateral.

The weighted average discount rate used to measure our operating lease liabilities as of December 31, 2025 and 2024 were 5.7% and 6.0%, respectively.

*The mark-to-market component of net periodic costs is determined based on discount rates as of year-end and actual asset returns during the year.

The expected long-term rate of return on pension assets was determined after considering the forward looking long-term asset returns by asset category and the expected investment portfolio mix.

Our pension investment strategy is to diversify the portfolio among asset categories to enhance the portfolio’s risk-adjusted return as well as insulate it from exposure to changes in interest rates. Our asset mix considers the duration of plan liabilities, historical and expected returns of the investments, and the funded status of the plan. The pension asset allocation is reviewed and actively managed based on the funded status of the plan. Based on the current funded status of the plan, our pension asset investment allocation guidelines are weighted heavily to fixed income securities. The plan keeps a minimal amount of cash available to fund benefit payments. See the following table for the plans' asset allocation.

Pension Plan Assets

Other assets are primarily insurance contracts for international plans. The U.S. equity common collective funds are predominately invested in equity securities actively traded in public markets. The international and global equity common collective funds have broadly diversified investments across economic sectors and focus on low volatility, long-term investments. The fixed income common collective funds consist primarily of publicly traded United States fixed interest obligations (principally investment grade bonds and government securities).

Level 1 assets are valued based on quoted market prices. Level 2 investments are valued based on quoted market prices and/or other market data for the same or comparable instruments and transactions of the underlying fixed income investments. The insurance contracts included in the other asset category are valued at the transacted price. Common collective funds are valued at the net asset value of units held by the fund at year-end. The unit value is determined by the total value of fund assets divided by the total number of units of the fund owned.

Note 10 — COMMITMENTS AND CONTINGENCIES

We have been notified by federal and state environmental agencies and by private parties that we may be a potentially responsible party (PRP) in connection with the environmental investigation and remediation of certain sites. While government agencies frequently assert that PRPs are jointly and severally liable at these sites, in our experience, the interim and final allocations of liability costs are generally made based on the relative contribution of waste. We may also initiate corrective and preventive environmental projects of our own to support safe and lawful activities at our operations. We believe that compliance with current governmental regulations at all levels will not have a material adverse effect on our financial position, results of operations or cash flows.

In September 2007, the United States District Court for the Western District of Kentucky (Court) in the case of Westlake Vinyls, Inc. v. Goodrich Corporation, et al., held that Avient must pay the remediation costs at the former Goodrich Corporation Calvert City facility (now largely owned and operated by Westlake Vinyls, Inc. (Westlake Vinyls)), together with certain defense costs of Goodrich Corporation. The rulings also provided that Avient can seek indemnification for contamination attributable to Westlake Vinyls. Following the rulings, the parties to the litigation agreed to settle all claims regarding past environmental costs incurred at the site. The settlement agreement provides a mechanism to pursue allocation of future remediation costs at the Calvert City site to Westlake Vinyls.

The environmental obligation at the site arose as a result of an agreement between The B.F. Goodrich Company (n/k/a Goodrich Corporation) and our predecessor, The Geon Company, at the time of the initial public offering in 1993. Under the agreement, The Geon Company agreed to indemnify Goodrich Corporation for certain environmental costs at the site. Neither Avient nor The Geon Company ever operated the facility.

Since 2009, Avient, along with respondents Westlake Vinyls and Goodrich Corporation, has worked with the United States Environmental Protection Agency (USEPA) to address the remedial activities at the site. The USEPA issued its Record of Decision (ROD) in September 2018. In April 2019, the respondents signed an Administrative Settlement Agreement and Order on Consent with the USEPA to conduct the remedial actions at the site. In February 2020, three companies signed the agreed Consent Decree and remedial action Work Plan, which received Federal Court approval in January 2021.

In 2023, the Company recognized charges of $20.6 million associated with the completion of certain remedial action activities at the site. Further, the Company received construction bids based on an interim design for the largest component of remedial action at Calvert City, the construction of a barrier wall around the site, which began in 2024. These construction cost updates resulted in an additional charge of $36.2 million in 2023. In 2024, the Company finalized the design and construction estimates for one phase of the barrier wall, as well as an updated remedial action timeline at the site, which resulted in charges of $19.8 million. Construction of the initial barrier wall section began in 2024 and was completed in the first quarter of 2025. In 2025, the Company recognized charges of $21.3 million associated with Calvert City, primarily driven by incremental investigation and remedial design work deemed necessary based on results of ongoing findings at the site. Further, this incremental work resulted in a two-year extension of the planned remedial action timeline, which also contributed to the charges. The remaining wall designs and construction are now expected to be completed in phases through 2030. As the Company completes further design work and begins construction on the remaining sections of the barrier wall, the Company will update its accrual, which was $133.2 million as of December 31, 2025, for any new information as it becomes available.

Total environmental accruals of $141.2 million and $146.0 million are reflected within Accrued expenses and other current liabilities and Other non-current liabilities in our Consolidated Balance Sheets as of December 31, 2025 and December 31, 2024, respectively. These undiscounted accruals represent our best estimate of probable future costs that we can reasonably estimate, based upon currently available information and technology and how the remedy will be implemented. It is reasonably possible that we could incur additional costs in excess of the amount accrued, which could be material to our Consolidated Statements of Income. However, such additional costs cannot currently be estimated as they are dependent upon the results of future testing and findings during the execution of remedial design and remedial action, changes in the Calvert City construction timeline, changes in regulations, technology development, new information, newly discovered conditions and other factors that are not currently known.

The following table details the changes in the environmental accrued liabilities:

(In millions)	2025		2024		2023
Balance at beginning of the year	$	146.0	$	157.2	$	118.3
Environmental expenses	23.4		35.0		69.6
Net cash payments	(28.2)		(46.1)		(30.7)
Currency translation	—		(0.1)		—
Balance at the end of year	$	141.2	$	146.0	$	157.2

The environmental expenses noted in the table above, primarily related to the ongoing remedial action at Calvert City, are included in Cost of sales within the Consolidated Statements of Income.

We recognized gains from insurance recoveries of $2.0 million, $34.7 million and $1.7 million in 2025, 2024 and 2023, respectively. These gains are included in Cost of sales within the Consolidated Statements of Income. Cash received from insurance recoveries totaled $36.0 million, $0.7 million and $1.7 million in 2025, 2024 and 2023, respectively. Further insurance recoveries related to remedial activities at the Calvert City site are expected to be immaterial.

Avient is subject to a broad range of claims, administrative and legal proceedings such as lawsuits that relate to contractual allegations, tax audits, product claims, personal injuries, and employment related matters. Although it is not possible to predict with certainty the outcome or cost of these matters, the Company believes our current reserves are appropriate and that these matters will not have a material adverse effect on the consolidated financial statements.

In 2025, Luxembourg recognized a statutory impairment that gave rise to a $28.9 million tax benefit. Further, in 2025, the Company completed an intercompany transfer of intellectual property between entities in different tax jurisdictions resulting in a net tax benefit of $12.1 million. These benefits increased deferred tax assets in Luxembourg; however, based on an evaluation of available evidence, the Company determined that it is more likely than not that a portion of these deferred tax assets will not be fully realized. As a result, the Company recorded a valuation allowance of $41.2 million in Luxembourg.

As previously disclosed for the years ended December 31, 2024 and 2023, prior to the adoption of ASU 2023-09, the effective tax rate differs from the statutory tax rate as follows:

In 2023, the tax rate included the recognition of tax benefits of 7.5% associated with tax impairments of investments in affiliates, driven in part from European restructuring actions. Further, we recognized a 5.4% tax benefit from federal and state capital losses associated with an international affiliate's tax status change in 2022. Finally, we recognized tax benefits from the reduction of uncertain tax positions as well as the U.S. R&D tax credit, which reduced the tax rate, 5.3% and 3.7%, respectively. Partially offsetting these benefits were non-deductible foreign interest, 5.3%, tax associated with foreign income repatriation, 3.9%, and an increase of our valuation allowance which impacted the rate 3.6%.

As of December 31, 2025, we had gross state net operating loss carryforwards of $68.1 million that expire between 2026 and 2044 or that have indefinite carryforward periods. Various international subsidiaries have gross net operating loss carryforwards totaling $357.4 million that expire between 2026 and 2042 or that have indefinite carryforward periods.

As of December 31, 2025, no tax provision has been made relating to undistributed earnings of certain non-U.S. subsidiaries, as these amounts continue to be indefinitely reinvested, consistent with our policy. The cash that is permanently reinvested is typically used for operations. It is not practical to estimate the additional income taxes and applicable withholding taxes that would be payable upon the remittance of such undistributed earnings. Taxes on certain foreign earnings as of December 31, 2025 and 2024 included in the Other deferred tax liabilities line in the table above are $10.0 million and $9.7 million, respectively.

We recognize interest and penalties related to uncertain tax positions in the tax provision. We had $2.2 million and $2.5 million accrued as of December 31, 2025 and 2024, respectively.

If all unrecognized tax benefits were recognized, the net impact on the tax provision would be a benefit of $9.8 million.

In December 2024, Avient received a Notice of Deficiency (Notice) from the U.S. Internal Revenue Service (IRS) proposing an adjustment to the 2019 tax year resulting from a disallowed capital loss. The proposed incremental tax associated with the Notice is $23.8 million plus estimated interest of $7.3 million. We contested the Notice by filing a petition in U.S. Tax Court on March 4, 2025. The IRS' answer to Avient's petition included an additional accuracy-related penalty of $4.8 million and is subject to interest. The Company believes that the proposed penalty is also without merit, and we intend to contest the penalty vigorously in U.S. Tax Court. However, there can be no assurance this dispute with the IRS will be resolved favorably. As of December 31, 2025, the Company has not recorded any income tax provision related to this matter; therefore an unfavorable ruling or settlement in U.S. Tax Court would adversely impact our effective tax rate and result in a cash tax payment.

Note 12 — SHARE-BASED COMPENSATION

Share-based compensation cost recognized in the accompanying Consolidated Statements of Income includes compensation cost for share-based payment awards based on an estimated grant date fair value. Share-based compensation expense is based on awards expected to vest and therefore has been reduced for estimated forfeitures.

56 AVIENT CORPORATION

In May 2020, our shareholders approved the Avient Corporation 2020 Equity and Incentive Compensation Plan (2020 Plan). This plan reserved 2.5 million common shares for the award of a variety of share-based compensation alternatives, including non-qualified stock options, incentive stock options, restricted stock, restricted stock units (RSUs), performance shares, performance units and stock appreciation rights (SARs). It is anticipated that all share-based grants and awards that are earned and exercised will be issued from Avient common shares that are held in treasury.

In May 2023, our shareholders voted to approve an amendment and restatement of the 2020 Plan (Amended 2020 Plan). The Amended 2020 Plan increases the number of common shares available for awards under the 2020 plan by 2.5 million common shares.

Share-based compensation is included in Selling and administrative expense. A summary of compensation expense by type of award follows:

(In millions)	2025		2024		2023
Stock appreciation rights	$	2.6	$	6.5	$	6.1
Performance shares	—		0.1		0.2
Restricted stock units	6.5		8.8		6.9
Total share-based compensation	$	9.1	$	15.4	$	13.2

Stock Appreciation Rights

During the years ended December 31, 2024 and 2023, the total number of SARs granted was 0.5 million and 0.5 million, respectively. No SARs were granted in 2025. Awards vest in one-third increments upon the later of the attainment of time-based vesting over a three-year service period and stock price targets. Awards granted in 2024 and 2023 are subject to an appreciation cap of 200% of the base price. SARs have contractual terms of ten years from the date of the grant.

The SARs were valued using a Monte Carlo simulation method as the vesting is dependent on the achievement of certain stock price targets. The SARs have time and stock price target requirements, both of which must be achieved in order to vest. Forfeitures were estimated at 3% per year based on our historical experience.

A summary of SAR activity for 2025 is presented below:

(In millions, except per share data)	Shares	Weighted-Average Exercise Price per Share		Weighted-Average Remaining Contractual Term	Aggregate Intrinsic value
Outstanding as of January 1, 2025	2.5	$	40.93	6.6	$	6.2
Exercised	(0.1)	34.16
Forfeited or expired	(0.1)	47.57
Outstanding as of December 31, 2025	2.3	$	40.76	5.5	$	0.2
Vested and exercisable as of December 31, 2025	1.6	$	38.01	4.7	$	0.2

The total intrinsic value of SARs exercised during 2025, 2024 and 2023 was $0.4 million, $5.6 million and $0.7 million, respectively. As of December 31, 2025, there was $0.7 million of total unrecognized compensation cost related to SARs, which is expected to be recognized over the weighted average remaining vesting period of 13 months.

Restricted Stock Units

RSUs represent contingent rights to receive one common share at a future date provided certain vesting criteria are met. During 2025, 2024 and 2023, the total number of RSUs granted were 0.2 million, 0.2 million and 0.3 million, respectively. In 2025, 0.2 million RSUs vested and 0.1 million RSUs were forfeited. RSUs granted in 2024 and 2023, which generally vest on the third anniversary of the grant date, were granted to executives and other key employees. RSUs granted in 2025 vest annually over a three-year period. Compensation expense is measured on the grant date using the quoted market price of our common shares and is recognized on a straight-line basis over the requisite service period.

As of December 31, 2025, 0.5 million RSUs remain unvested with a weighted-average grant date fair value of $41.09. Unrecognized compensation cost for RSUs at December 31, 2025 was $11.1 million, which is expected to be recognized over the weighted average remaining vesting period of 20 months.

Note 13 — SEGMENT INFORMATION

Operating segments are components of the Company about which separate financial information is available and evaluated on a regular basis by the chief operating decision maker (CODM), which is the Company's chief executive officer. Operating income is the primary segment performance measure that is reported to CODM. Our CODM utilizes this measure to determine appropriate resource allocations to our segments in the annual planning process and to periodically assess segment performance, primarily by evaluating actual results in comparison to the annual operating plan and forecast. Operating income at the segment level does not include corporate general and administrative expenses that are not allocated to segments, restructuring charges, share-based compensation costs, environmental remediation costs and associated recoveries, asset impairments, acquisition-related charges, mark-to-market adjustments on pension and other post-retirement obligations, and certain other items that are not included in the measure of segment profit or loss that is reported to and reviewed by our CODM. These costs are included in Corporate.

Segment assets are primarily customer receivables, inventories, net property, plant and equipment, intangible assets and goodwill. Corporate assets and liabilities primarily include cash, debt, pension and other employee benefits, environmental liabilities, and other unallocated corporate assets and liabilities. The accounting policies of each segment are consistent with those described in Note 1, Description of Business and Summary of Significant Accounting Policies.

Note 14 — DERIVATIVES AND HEDGING

We are exposed to market risks, such as changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures we may enter into various derivative transactions. We formally assess, designate and document, as a hedge of an underlying exposure, the qualifying derivative instrument that will be accounted for as an accounting hedge at inception. Additionally, we assess both at inception and at least quarterly thereafter, whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures. In accordance with ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12), that ongoing assessment may be done qualitatively for highly effective relationships.

Net Investment Hedge

As a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we have executed cross-currency swaps, in which we pay fixed-rate interest in Euros and receive fixed-rate interest in U.S. dollars related to our future obligations to exchange Euros for U.S. dollars. In November 2024, the Company completed a transaction to effectively amend and extend cross-currency swaps maturing in May 2025, which had a combined notional amount of €1,467.2 million. The liability position of the existing cross-currency swaps was blended into new cross-currency swap agreements. In November 2024, the Company also entered into an additional cross-currency swap agreement, which had a combined notional amount of €208.2 million, to further hedge its net investment in its European operations.

We designated the cross-currency swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. The changes in fair value of the derivative instruments that are designated and qualify as hedges of net investments in foreign operations are recognized within Accumulated Other Comprehensive Income (Loss) (AOCI) to offset the changes in the values of the net investment being hedged. For the years ended December 31, 2025 and 2024, a loss of $210.2 million and a gain of $77.3 million, respectively, were recognized within translation adjustments in AOCI, net of tax.

These cross-currency swaps effectively convert a portion of our U.S. dollar denominated fixed-rate debt to Euro denominated fixed-rate debt. Included in Interest expense, net within the Consolidated Statements of Income are benefits of $36.1 million, $38.4 million and $38.8 million for the years ended December 31, 2025, 2024 and 2023, respectively, related to net interest payments received from counterparties.

61 AVIENT CORPORATION

All of our derivative assets and liabilities measured at fair value are classified as Level 2 within the fair value hierarchy. We determine the fair value of our derivatives based on valuation methods, which project future cash flows and discount the future amounts present value using market based observable inputs, including interest rate curves and foreign currency rates. The fair value of derivative financial instruments recognized in the Consolidated Balance Sheets as of December 31, 2025 and 2024 is as follows:

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure controls and procedures

Avient’s management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness of the design and operation of Avient’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2025. Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, 2025.

Management’s Annual Report On Internal Control Over Financial Reporting

The following report is provided by management in respect of Avient’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act):

1.	Avient’s management is responsible for establishing and maintaining adequate internal control over financial reporting.
2.	Under the supervision of and with participation of Avient’s management, including the Chief Executive Officer and the Chief Financial Officer, we conducted an evaluation of the effectiveness of internal control over financial reporting as of December 31, 2025 based on the guidelines established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) (2013 Framework). Management believes that the 2013 Framework is a suitable framework for its evaluation of financial reporting because it is free from bias, permits reasonably consistent qualitative and quantitative measurements of Avient’s internal control over financial reporting, is sufficiently complete so that those relevant factors that would alter a conclusion about the effectiveness of Avient’s internal control over financial reporting are not omitted and is relevant to an evaluation of internal control over financial reporting.
3.	Based on the results of our evaluation, management has concluded that such internal control over financial reporting was effective as of December 31, 2025. There were no material weaknesses in internal control over financial reporting identified by management. The results of management's assessment were reviewed with our Audit Committee.
4.	Ernst & Young LLP, who audited the consolidated financial statements of Avient for the year ended December 31, 2025, also issued an attestation report on Avient’s internal control over financial reporting under Auditing Standard No. 2201 of the Public Company Accounting Oversight Board. This attestation report is set forth on page 28 of this Annual Report on Form 10-K and is incorporated by reference into this Item 9A.

Changes in internal control over financial reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations in internal control over financial reporting

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.

ITEM 9B. OTHER INFORMATION

Attn: #ParticipantName#

Avient Corporation

AVIENT CORPORATION INCENTIVE AWARD

Grant of Restricted Stock Units

Subject to the terms and conditions of the Avient Corporation 2020 Equity and Incentive Compensation Plan, as amended and restated effective May 11, 2023 (the “Plan”), and this letter agreement (this “Agreement”), the Compensation Committee of the Board of Directors (the “Committee”) of Avient Corporation (“Avient”) [or its authorized delegatee]1 has granted to you, as of #GrantDate#, the following award:

#QuantityGranted# restricted stock units (the “Restricted Stock Units”), which shall vest in accordance with the terms set forth in this Agreement. Each Restricted Stock Unit shall represent one hypothetical common share, par value US$0.01 per share, of Avient (a “Common Share”) and shall at all times be equal in value to one Common Share.

A copy of the Plan is available for your review through the Corporate Secretary’s office. Unless otherwise indicated, the capitalized terms used in this Agreement shall have the same meanings as set forth in the Plan.

1.Vesting of Restricted Stock Units.

(a)Normal Vesting. Subject to the provisions of the Plan and this Agreement, the Restricted Stock Units shall vest in substantially equal installments on each of the following dates: #VestDate_1#, #VestDate_2# and #VestDate_3# (each date, a “Vesting Date”, and the three-year vesting period from #GrantDate# until

1 Note to Avient: This language should only be included for RSU grants that are approved under the CEO’s delegation authority rather than by the Compensation Committee.

2026 RSU Award Agreement (US)

#VestDate_3#, the “Restriction Period”), provided that you remain in the continuous employ of Avient or a Subsidiary on each such Vesting Date.

(b)Disability or Death. Notwithstanding the provisions of Section 1(a) of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the end of the Restriction Period due to (i) your permanent and total disability (as defined under the relevant disability plan or program of Avient or a Subsidiary in which you then participate) or (ii) your death, you shall vest in a number of Restricted Stock Units equal to the product of (A) one-third of the total number of Restricted Stock Units subject to this Agreement, multiplied by (B) a fraction, the numerator of which is the number of days that have elapsed between the Vesting Date immediately preceding your termination date (or, in the event your employment terminates prior to the first Vesting Date, #GrantDate#) and the date your employment by Avient or a Subsidiary terminates, and the denominator of which is 365 (or 366, if your employment terminates in 2028). The remaining portion of the Restricted Stock Units will be forfeited.

(c)Retirement. Notwithstanding the provisions of Sections 1(a) and 1(b) of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the end of the Restriction Period due to (i) your retirement at age 55 or older with at least 10 years of service (“55+ Retirement”) or (ii) your retirement at age 58 or older with at least 5 years of service (“58+ Retirement”), you shall vest in all of the Restricted Stock Units that remain unvested as of the date of your 55+ Retirement or 58+ Retirement, as applicable.

(d)Termination without Cause Prior to a Change of Control. Notwithstanding the provisions of Sections 1(a), 1(b) and 1(c), if your employment with Avient or a Subsidiary is terminated by Avient or a Subsidiary without Cause (as defined in Section 1(f)(i) below) prior to the end of the Restriction Period and prior to a Change of Control in the circumstances described below, any Restricted Stock Units that remain unvested as of such termination shall vest as follows:

(i)If, as of the date of your termination without Cause (as defined in Section 1(f)(i)), (A) you have been designated as an officer for purposes of Section 16 of the Exchange Act (a “Section 16 Officer”) for at least two consecutive years immediately prior to such date and are not eligible for a 55+ Retirement or a 58+ Retirement (“Retirement Eligible”) or (B) you have not been designated a Section 16 Officer for at least two consecutive years immediately prior to such date and you are Retirement Eligible, you shall vest on the date of your termination without Cause in a number of Restricted Stock Units equal to the product of (I) one-third of the total number of Restricted Stock Units subject to this Agreement, multiplied by (II) a fraction, the numerator of which is the number of days that have elapsed between the Vesting Date immediately preceding your termination date (or, in the event your employment terminates prior to the first Vesting Date, #GrantDate#) and the date your employment by Avient or a Subsidiary terminates, and the denominator of which is 365 (or 366, if your employment terminates in 2028). Any remaining portion of the Restricted Stock Units will be forfeited.

(ii)If, as of the date of your termination without Cause (as defined in Section 1(f)(i)), you have been designated a Section 16 Officer for more than two consecutive years immediately prior to such date and are Retirement

2026 RSU Award Agreement (US)

Eligible, you shall vest on the date of your termination without Cause in all of the Restricted Stock Units that remain unvested as of such date.

(e)Change of Control. Notwithstanding the provisions of Sections 1(a), 1(b), 1(c) and 1(d) of this Agreement, if a Change of Control occurs prior to the end of the Restriction Period and you remain in the continuous employ of Avient or a Subsidiary, any Restricted Stock Units that remain unvested as of such Change of Control shall vest as follows:

(i)notwithstanding anything to the contrary herein, except to the extent that a Replacement Award is provided to you in accordance with Section 1(e)(ii) to continue, replace or assume the Restricted Stock Units covered by this Agreement (the “Replaced Award”), all of the unvested Restricted Stock Units shall vest on the date of such Change of Control.

(ii)for purposes of this Agreement, a “Replacement Award” means an award (A) of the same type (e.g., time-based restricted stock units) as the Replaced Award, (B) that has a value at least equal to the value of the Replaced Award, (C) that relates to publicly traded equity securities of Avient or its successor in the Change of Control or another entity that is affiliated with Avient or its successor following the Change of Control (the “Successor”), (D) if you are subject to U.S. federal income tax under the Code, the tax consequences of which under the Code are not less favorable than the tax consequences of the Replaced Award, (E) that vests in full upon a termination of your employment with Avient, a Subsidiary or the Successor without Cause (as defined in Section 1(f)(ii) below) by Avient, a Subsidiary or the Successor or by you for Good Reason (as defined in Section 1(f)(iii) below), in either case within a period of two years after the Change of Control, and (F) the other terms and conditions of which are not less favorable to you than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change of Control).  A Replacement Award may be granted only to the extent it does not result in the Replaced Award or Replacement Award failing to comply with or be exempt from Section 409A of the Code.  Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the two preceding sentences are satisfied.  The determination of whether the conditions of this Section 1(e)(ii) are satisfied will be made by the Committee, as constituted immediately before the Change of Control, in its sole discretion.

(iii)if, after receiving a Replacement Award and within a period of two years after the Change of Control, (A) your employment is terminated without Cause (as defined in Section 1(f)(ii) below) by Avient, a Subsidiary or the Successor, as applicable, or (B) you terminate your employment with Avient, a Subsidiary or the Successor, as applicable, for Good Reason (as defined in Section 1(f)(iii) below), the Replacement Award, to the extent it remains unvested, shall become fully vested with respect to the time-based restricted stock units covered by such Replacement Award upon such termination.

(iv)if a Replacement Award is provided, notwithstanding anything in this Agreement to the contrary, any outstanding Restricted Stock Units subject to this Agreement that at the time of the Change of Control are not subject

2026 RSU Award Agreement (US)

to a “substantial risk of forfeiture” (within the meaning of Section 409A of the Code) will be deemed to be vested at the time of such Change of Control.

(f)For purposes of this Agreement:

(i)in the event of a termination of your employment without Cause pursuant to Section 1(d) of this Agreement, “Cause” shall mean (A) your serious violation or deliberate disregard of Avient or a Subsidiary’s policies; (B) your gross dereliction in the performance of your job duties and responsibilities; (C) your violation of Avient’s Code of Conduct or any successor document; (D) your misappropriation of property of Avient or a Subsidiary; (E) your commission of an act of fraud upon, or bad faith, dishonesty or disloyalty toward Avient or any of its Subsidiaries; (F) your breach of any restrictive covenants or written obligations to Avient or a Subsidiary in respect of confidentiality and/or the use or ownership of proprietary information; (G) an event of egregious misconduct involving serious moral turpitude to the extent that, in the reasonable judgment of the Committee, your credibility and reputation no longer conforms to the standards applicable to Avient’s executives; or (H) an act or omission that Avient reasonably determines may prejudice significantly its best interests if your employment is not terminated.

(ii)in the event of a termination of your employment without Cause following a Change of Control pursuant to Section 1(e) of this Agreement, “Cause” shall mean (A) the willful and continued failure by you to substantially perform your duties with Avient or any Subsidiary, which failure causes material and demonstrable injury to Avient or any Subsidiary (other than any such failure resulting from your incapacity due to physical or mental illness), after a demand for substantial performance is delivered to you by the Committee or the Board which specifically identifies the manner in which the Committee or the Board believes that you have not substantially performed your duties, and after you have been given a period of at least 30 days to correct your performance, or (B) the willful engaging by you in other gross misconduct materially and demonstrably injurious to Avient or a Subsidiary. For purposes of this Section 1(f)(ii), no act or failure to act, on your part shall be considered “willful” unless conclusively demonstrated to have been done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interests of Avient or a Subsidiary.

(iii)“Good Reason” shall mean (A) a material diminution in your duties or responsibilities at Avient or a Subsidiary; (B) a material reduction in your base salary, other than a reduction or failure that is part of a broad reduction in base salary generally applicable to Avient’s other similarly-situated employees; (C) your permanent reassignment to another primary work location more than 50 miles from your then-current work location; or (D) a material breach by Avient or a Subsidiary of any obligation under any material agreement between you and Avient or a Subsidiary; provided, that no later than 30 days following an event constituting Good Reason, you give notice to Avient or a Subsidiary of the occurrence of such event, Avient or a Subsidiary fails to remedy the event within 30 calendar days after receipt of such written notice and your employment is terminated within 60 days thereafter.

2026 RSU Award Agreement (US)

(g)Notwithstanding the provisions of Sections 1(a), 1(b), 1(c), 1(d) and 1(e) of this Agreement and to the extent permitted by applicable law, a number of Restricted Stock Units may vest and become payable prior to a Vesting Date or other vesting event described in Sections 1(b), 1(c), 1(d) and 1(e) of this Agreement in an amount that is sufficient to cover any employment tax that becomes payable by you with respect to the Restricted Stock Units prior to such Vesting Date or other vesting event, as applicable.

2.Other Termination. If your employment with Avient or a Subsidiary terminates before the end of the Restriction Period for any reason other than as set forth in Section 1(b), Section 1(c), Section 1(d) or Section 1(e)(iii) of this Agreement, all of the Restricted Stock Units that remain unvested as of the termination of your employment will be forfeited. For the avoidance of doubt, such reasons shall include, without limitation, a termination of your employment with Avient or a Subsidiary for Cause (as defined in Section 1(f)(i) or Section 1(f)(ii), as applicable, depending on whether a termination of your employment occurs prior to or following a Change of Control), regardless of whether you are Retirement Eligible at such time.

3.Payment of Restricted Stock Units.

(a)The Restricted Stock Units that vest pursuant to Section 1 of this Agreement will be paid in Common Shares transferred to you within 30 business days following the applicable Vesting Date; provided, however, that, subject to Section 3(c) of this Agreement, the Restricted Stock Units that vest in accordance with Section 1(b), 1(c), 1(d), 1(e)(i) or 1(e)(iii) of this Agreement will be paid within 30 business days following the date of the termination of your employment or the date of the Change of Control, whichever applies.

(b)If Avient determines that it is required to withhold taxes from any payment, Avient will withhold Common Shares with a value equal to the amount of these taxes from the payment, and such Common Shares will be valued at an amount equal to the fair market value of such Common Shares on the date of payment.

(c)If the event triggering the right to payment under Section 3(a) of this Agreement does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything herein to the contrary, the payment of Common Shares will be made to you, to the extent necessary to comply with Section 409A of the Code, on the earliest of (i) your “separation from service” with Avient or a Subsidiary (determined in accordance with Section 409A of the Code) that occurs after the event giving rise to payment; (ii) the Vesting Date applicable to the Restricted Stock Units attributable to such Common Shares; or (iii) your death. In addition, for the avoidance of doubt, Section 18(c) of the Plan applies to any payment of Common Shares made pursuant to this Agreement.

4.Dividend, Voting and Other Rights. You shall have no rights of ownership in the Restricted Stock Units or the Common Shares underlying the Restricted Stock Units and you shall have no right to vote the underlying Common Shares until the date on which any Common Shares are transferred to you pursuant to Section 3 of this Agreement. While the Restricted Stock Units are still outstanding, on the record date for each cash dividend, if any, that Avient pays to holders of Common Shares generally (the “Record Date”), you shall be entitled to a number of additional whole Restricted Stock Units determined by dividing (a) the product of (i) the dollar amount of the cash dividend paid per Common Share and (ii) the total number of Restricted Stock Units (including dividend equivalents paid thereon) credited to you as of the Record Date, by (b) the

2026 RSU Award Agreement (US)

Market Value per Share on the Record Date. Any dividend equivalents credited hereunder shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the Restricted Stock Units to which the dividend equivalents were credited.

5.Non-Assignability. The Restricted Stock Units are personal to you and are not transferable by you other than by will or the laws of descent and distribution. Any purported transfer or encumbrance in violation of the provisions of this Section 5 shall be void, and the other party to any such purported transaction shall not obtain any right to or interest in such Restricted Stock Units.

6.Adjustments. In the event of any extraordinary cash dividend, stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of Avient, merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial or complete liquidation or other distribution of assets, issuance of rights or warrants to purchase securities, or any other corporate transaction or event having an effect similar to any of the foregoing, the Committee shall make or provide for such adjustments in the number of and kind of Common Shares covered by the Restricted Stock Units then held by you, and in other award terms, as the Committee, in its sole discretion, exercised in good faith, determines is equitably required to prevent dilution or enlargement of your rights in connection with such transaction or event. If any such transaction or event occurs or in the event of a Change of Control, the Committee may provide in substitution for outstanding Restricted Stock Units such alternative consideration (including, without limitation, in the form of cash, securities or other property) as it may determine to be equitable in the circumstances and shall require in connection therewith the surrender of the Restricted Stock Units subject to this Agreement. No adjustment provided for in this Section 6 or Section 12 of the Plan will require Avient to issue any fractional shares.

7.Miscellaneous.

(a)Construction. The contents of this Agreement are subject in all respects to the terms and conditions of the Plan as approved by the Board and the shareholders of Avient, which are controlling. The interpretation and construction by the Board and/or the Committee of any provision of the Plan or this Agreement shall be final and conclusive upon you, your estate, executor, administrator, beneficiaries, personal representative and guardian and Avient and its successors and assigns.

(b)Leave of Absence. Any absence or leave approved by a duly constituted officer of Avient or any of its Subsidiaries will not be considered an interruption or termination of your service under this Agreement.

(c)Data Privacy. The grant of the Restricted Stock Units is discretionary and will not be considered to be an employment contract or a part of your terms and conditions of employment or of your salary or compensation. Information about you and your participation in the Plan, including, without limitation, your name, home address, email address and telephone number, date of birth, social insurance number, passport number or other identification number, salary, nationality, job title, any shares of stock or directorships held in Avient, and details of the Restricted Stock Units or other entitlement to shares of stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in your favor may be collected, recorded, held, used and disclosed by Avient and any of its Subsidiaries and any non-Avient entities engaged by Avient to provide services in connection with this grant (a “Third Party Administrator”), for any purpose related to the administration of the Plan. You understand that Avient and its Subsidiaries may

2026 RSU Award Agreement (US)

transfer such information to Third Party Administrators, regardless of whether such Third Party Administrators are located within your country of residence. Please refer to the Avient Global Associate Processing Notice, a copy of which has been provided or otherwise made available to you, for more information about the personal information that Avient collects about you and the purposes for which Avient uses such data. If you are a California resident, such notice is intended to satisfy Avient’s requirements under the California Consumer Protection Act.

(d)Amendment. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto. The terms and conditions of this Agreement may not be modified, amended or waived, except by an instrument in writing signed by a duly authorized executive officer at Avient. Notwithstanding the foregoing, no amendment shall adversely affect your rights under this Agreement without your consent.

(e)No Modifications to Existing Agreements. Except as specifically referenced herein, nothing in this Agreement impacts, changes, or otherwise modifies any existing agreements between you and Avient.

(f)Clawback. Notwithstanding anything in this Agreement to the contrary, you acknowledge and agree that (i) this Agreement, the Restricted Stock Units (and any settlement thereof) and any other performance-based incentive compensation or related amounts held or received by you are subject to any Avient clawback policy applicable to you, under their terms and conditions as may be in effect from time to time, including, without limitation, to implement Section 10D of the Exchange Act and any applicable rules or regulations (including applicable rules and regulations of any national securities exchange or national securities association on which the Common Shares may be traded) (the “Compensation Recovery Policy”), and (ii) that any relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of any such clawback policy from and after the effective date thereof. Further, by accepting the Restricted Stock Units covered by this Agreement, you (A) consent to be bound by the terms of the Compensation Recovery Policy, as applicable, (B) agree and acknowledge that you are obligated to and will cooperate with, and will provide any and all assistance necessary to, Avient in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Avient policy, and (C) agree that Avient may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy. Such cooperation and assistance shall include (but is not limited to) executing, completing and submitting any documentation necessary, or consenting to action by Avient, to facilitate the recovery or recoupment by Avient from you of any such compensation or other amounts, including from your accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

(g)Investigations. Notwithstanding anything to the contrary in this Agreement or in any other agreement, contract or arrangement with Avient or a Subsidiary, or in any policy, procedure or practice of Avient or a Subsidiary (collectively, the “Arrangements”), (i) nothing in the Arrangements or otherwise limits your right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency

2026 RSU Award Agreement (US)

(including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002), and (ii) nothing in the Arrangements or otherwise prevents you from, without prior notice to Avient, providing information (including documents) to governmental authorities or agencies regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities or agencies regarding possible legal violations, and for purposes of clarity you are not prohibited from providing information (including documents) voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act. Avient nonetheless asserts and does not waive its attorney-client privilege over any information appropriately protected by privilege. The terms of this Section 7(g) are referred to as the “Protected Rights,” and the terms of this Agreement are subject to the Protected Rights.

8.Notice. All notices under this Agreement to Avient must be delivered personally or mailed to Avient Corporation at Avient Center, 33587 Walker Road, Avon Lake, Ohio 44012, Attention: Corporate Secretary. Avient’s address may be changed at any time by written notice of such change to you. Also, all notices under this Agreement to you will be delivered personally or mailed to you at your address as shown from time to time in Avient’s records.

9.Compliance with Section 409A of the Code.

Subject to the terms and conditions of the Avient Corporation 2020 Equity and Incentive Compensation Plan, as amended and restated effective May 11, 2023 (the “Plan”), and this letter agreement (this “Agreement”), the Compensation Committee of the Board of Directors (the “Committee”) of Avient Corporation (“Avient”) has granted to you, as of #GrantDate#, the following award:

#QuantityGranted# performance units (the “Performance Units”), with each such Performance Unit being equal in value to US$1.00, payment of which depends on Avient’s performance as set forth in this Agreement and in your Statement of Performance Goals.

A copy of the Plan is available for your review through the Corporate Secretary’s office. Unless otherwise indicated, the capitalized terms used in this Agreement shall have the same meanings as set forth in the Plan.

1.Performance Units.

(a)Subject to the provisions of the Plan and this Agreement, your right to receive all or any portion of the Performance Units will be contingent upon the achievement of certain management objectives (the “Management Objectives”), as set forth in your Statement of Performance Goals. The achievement of the Management Objectives will be measured with respect to the period beginning on January 1, 2026 and ending on December 31, 2028 (the “Performance Period”).

2026 PU Award Agreement (US)

(b)Sixty-seven percent (67%) of the Performance Units (the “EPS Performance Units”) will be earned based solely on achievement of performance goals relating to Avient’s Adjusted Earnings per Share (“Adjusted EPS”), as defined in your Statement of Performance Goals, and the remaining thirty-three percent (33%) of the Performance Units (the “rTSR Performance Units”) will be earned based solely on achievement of performance goals relating to Avient’s Relative Total Shareholder Return (“rTSR”), as defined in your Statement of Performance Goals.

2.Earning of Performance Units.

(a)EPS Performance Units. The EPS Performance Units may be earned as follows:

(i)Threshold. If, upon the conclusion of the Performance Period, Adjusted EPS equals the threshold level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 50% of the EPS Performance Units shall become earned.

(ii)Target. If, upon the conclusion of the Performance Period, Adjusted EPS equals the target level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 100% of the EPS Performance Units shall become earned.

(iii)Equals or Exceeds Maximum. If, upon the conclusion of the Performance Period, Adjusted EPS equals or exceeds the maximum level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 200% of the EPS Performance Units shall become earned.

(iv)Between Threshold and Target or Target and Maximum. If, upon the conclusion of the Performance Period, Adjusted EPS is greater than the threshold level, but less than the target level, or greater than the target level, but less than the maximum level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then a proportionate percentage of the EPS Performance Units shall become earned, as determined by mathematical interpolation and rounded up to the nearest whole unit.

(v)Below Threshold. In no event shall any EPS Performance Units become earned if actual performance for the Performance Period falls below the threshold level for Adjusted EPS or if the Committee does not certify that the Management Objectives have been satisfied with respect to the EPS Performance Units for the Performance Period.

(b)rTSR Performance Units. The rTSR Performance Units may be earned as follows:

(i)Threshold. If, upon the conclusion of the Performance Period, rTSR equals the threshold level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then 50% of the rTSR Performance Units shall become earned.

2026 PU Award Agreement (US)

(ii)Target. If, upon the conclusion of the Performance Period, rTSR equals the target level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then 100% of the rTSR Performance Units shall become earned.

(iii)Equals or Exceeds Maximum. If, upon the conclusion of the Performance Period, rTSR equals or exceeds the maximum level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then 200% of the rTSR Performance Units shall become earned.

(iv)Between Threshold and Target or Target and Maximum. If, upon the conclusion of the Performance Period, rTSR is greater than the threshold level, but less than the target level, or greater than the target level, but less than the maximum level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then a proportionate percentage of the rTSR Performance Units shall become earned, as determined by mathematical interpolation and rounded up to the nearest whole unit.

(v)Below Threshold. In no event shall any rTSR Performance Units become earned if actual performance for the Performance Period falls below the threshold level for rTSR or if the Committee does not certify that the Management Objectives have been satisfied with respect to the rTSR Performance Units for the Performance Period.

(c)If the Committee determines that a change in the business, operations, corporate structure or capital structure of Avient, the manner in which it conducts business or other events or circumstances render the Management Objectives to be unsuitable, the Committee may modify such Management Objectives or the related levels of achievement, in whole or in part, as the Committee deems appropriate.

(d)Subject to the provisions of Sections 3, 4, 5 and 6 of this Agreement, your right to receive any Performance Units is contingent upon your remaining in the continuous employ of Avient or a Subsidiary through the payment date, which shall be a date in 2029 determined by the Committee (or its authorized delegatee) and shall occur no later than March 15, 2029 (the “Payment Date”).

(e)Notwithstanding the provisions of Section 4, 5 or 6 of this Agreement and to the extent permitted by applicable law, a number of Performance Units may become non-forfeitable and payable prior to the Payment Date in an amount that is sufficient to cover any employment tax that becomes payable by you with respect to the Performance Units prior to the Payment Date.

3.Change of Control. Subject to Section 8,

(a)if a Change of Control occurs prior to the Payment Date or forfeiture of the Performance Units and while you remain in the continuous employ of Avient or a Subsidiary, then, except to the extent that a Replacement Award is provided to you in accordance with Section 3(b) of this Agreement to continue, replace or assume the Performance Units covered by this Agreement (the “Replaced

2026 PU Award Agreement (US)

Award”), the number of Performance Units under this Agreement that shall be deemed fully earned shall equal the greater of (i) the target number of Performance Units granted pursuant to this Agreement; and (ii) the number of Performance Units earned based on the achievement of the performance measures specified in your Statement of Performance Goals as if the date of the Change of Control had been the last day of the Performance Period (as determined by the Committee as constituted immediately prior to the Change of Control) (but in no event may negative discretion be exercised with respect to the number of Performance Units earned). Any Performance Units that are not earned in accordance with the foregoing sentence shall terminate and be forfeited.

(b)for purposes of this Agreement, a “Replacement Award” means an award: (i) consisting of an award of performance units; (ii) that has a value at least equal to the value of the Replaced Award; (iii) that relates to publicly traded equity securities of Avient or its successor in the Change of Control or another entity that is affiliated with Avient or its successor following the Change of Control (the “Successor”); (iv) if you are subject to U.S. federal income tax under the Code, the tax consequences of which under the Code are not less favorable than the tax consequences of the Replaced Award; (v) that vests upon a termination of your employment with Avient, a Subsidiary or the Successor for Good Reason (as defined in Section 3(d)(ii) below) or without Cause (as defined in Section 3(d)(i) below) by Avient, a Subsidiary or the Successor, in each case within a period of two years after the Change of Control based on actual performance through the date of such termination; and (vi) the other terms and conditions of which are not less favorable to you than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change of Control).  A Replacement Award may be granted only to the extent it does not result in the Replaced Award or Replacement Award failing to comply with or be exempt from Section 409A of the Code.  Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the two preceding sentences are satisfied.  The determination of whether the conditions of this Section 3(b) are satisfied will be made by the Committee, as constituted immediately before the Change of Control, in its sole discretion.

(c)if a Replacement Award is provided, (i) the terms of the Replacement Award will govern the vesting and payment of the Replacement Award; and (ii) notwithstanding anything in this Agreement to the contrary, any outstanding Performance Units subject to this Agreement that at the time of the Change of Control are not subject to a “substantial risk of forfeiture” (within the meaning of Section 409A of the Code) will be deemed fully earned at the time of such Change of Control and will be paid as provided in Section 8(b) of this Agreement.

(d)For purposes of this Section 3:

(i)“Cause” shall mean (A) the willful and continued failure by you to substantially perform your duties with Avient or any Subsidiary, which failure causes material and demonstrable injury to Avient or any Subsidiary (other than any such failure resulting from your incapacity due

2026 PU Award Agreement (US)

to physical or mental illness), after a demand for substantial performance is delivered to you by the Committee or the Board which specifically identifies the manner in which the Committee or the Board believes that you have not substantially performed your duties, and after you have been given a period of at least 30 days to correct your performance, or (B) the willful engaging by you in other gross misconduct materially and demonstrably injurious to Avient or a Subsidiary. For purposes of this Section 3(d)(i), no act or failure to act, on your part shall be considered “willful” unless conclusively demonstrated to have been done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interests of Avient or a Subsidiary.

(ii)“Good Reason” shall mean (A) a material diminution in your duties or responsibilities at Avient or a Subsidiary; (B) a material reduction in your base salary, other than a reduction or failure that is part of a broad reduction in base salary generally applicable to Avient’s other similarly-situated employees; (C) your permanent reassignment to another primary work location more than 50 miles from your then- current work location; or (D) a material breach by Avient or a Subsidiary of any obligation under any material agreement between you and Avient or a Subsidiary; provided, that no later than 30 days following an event constituting Good Reason, you give notice to Avient or a Subsidiary of the occurrence of such event, Avient or a Subsidiary fails to remedy the event within 30 calendar days after receipt of such written notice and your employment is terminated within 60 days thereafter.

4.Disability or Death. Subject to Section 8 of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the Payment Date and, to the extent a Replacement Award is not granted, prior to a Change of Control due to (a) permanent and total disability (as defined under the relevant disability plan or program of Avient or a Subsidiary in which you then participate) or (b) death, Avient shall pay to you or your executor or administrator, as the case may be, on the Payment Date, the product of (i) the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period, multiplied by (ii) a fraction, the numerator of which is the number of days during the Performance Period commencing on the first day of the Performance Period and extending through the date of your termination pursuant to one of the events described in clause (a) or (b) above, and the denominator of which is 1,096.

5.Retirement. Subject to Section 8 of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the Payment Date due to (a) your retirement at age 55 or older with at least 10 years of service (“55+ Retirement”) or (b) your retirement at age 58 or older with at least 5 years of service (“58+ Retirement”), Avient shall pay to you on the Payment Date the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period.

6.Termination without Cause Prior to a Change of Control. Subject to Section 8 of this Agreement, if your employment with Avient or a Subsidiary is terminated by Avient or a

2026 PU Award Agreement (US)

Subsidiary without Cause (as defined in Section 6(c)) prior to the Payment Date and prior to a Change of Control, the Performance Units shall vest as follows:

(a)if, as of the date of your termination without Cause (as defined in Section 6(c)), (i) you have been designated as an officer for purposes of Section 16 of the Exchange Act (a “Section 16 Officer”) for at least two consecutive years immediately prior to such date and are not eligible for a 55+ Retirement or a 58+ Retirement (“Retirement Eligible”) or (ii) you have not been designated a Section 16 Officer for at least two consecutive years immediately prior to such date and you are Retirement Eligible, Avient shall pay to you on the Payment Date the product of (A) the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period, multiplied by (B) a fraction, the numerator of which is the number of days during the Performance Period commencing on the first day of the Performance Period and extending through the date of your termination without Cause, and the denominator of which is 1,096.

(b)if, as of the date of your termination without Cause (as defined in Section 6(c)), you have been designated a Section 16 Officer for more than two consecutive years immediately prior to such date and are Retirement Eligible, Avient shall pay to you on the Payment Date the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period.

(c)for purposes of this Section 6, “Cause” shall mean (i) your serious violation or deliberate disregard of Avient or a Subsidiary’s policies; (ii) your gross dereliction in the performance of your job duties and responsibilities; (iii) your violation of Avient’s Code of Conduct or any successor document; (iv) your misappropriation of property of Avient or a Subsidiary; (v) your commission of an act of fraud upon, or bad faith, dishonesty or disloyalty toward Avient or any of its Subsidiaries; (vi) your breach of any restrictive covenants or written obligations to Avient or a Subsidiary in respect of confidentiality and/or the use or ownership of proprietary information; (vii) an event of egregious misconduct involving serious moral turpitude to the extent that, in the reasonable judgment of the Committee, your credibility and reputation no longer conforms to the standards applicable to Avient’s executives; or (viii) an act or omission that Avient reasonably determines may prejudice significantly its best interests if your employment is not terminated.

7.Other Termination. If your employment with Avient or a Subsidiary terminates before the Payment Date for any reason other than as set forth in Section 3, 4, 5 or 6 above, the Performance Units will be forfeited. For the avoidance of doubt, such reasons shall include, without limitation, a termination of your employment with Avient or a Subsidiary for Cause (as defined in Section 3(d)(i) or Section 6(c), as applicable,

2026 PU Award Agreement (US)

depending on whether a termination of your employment occurs prior to or following a Change of Control), regardless of whether you are Retirement Eligible at such time.

8.Payment of Performance Units.

(a)Payment of any Performance Units that become earned as set forth herein will be made in the form of cash. The amount of the cash payment to be made shall be determined by multiplying (i) the number of Performance Units earned pursuant to Section 2, 3, 4, 5 or 6 above by (ii) US$1.00. Except as provided in Section 8(b) of this Agreement, payment will be made on the Payment Date. If Avient determines that it is required to withhold any federal, state, local or foreign taxes from any payment, Avient will withhold the amount of these taxes from the payment.

(b)Notwithstanding Section 8(a), to the extent that the Performance Units are earned on the date of the Change of Control pursuant to Section 3(a) or 3(c) of this Agreement, payment will be made within 30 days following the date of the Change of Control. If the Change of Control triggering the right to payment under Section 3(a) or 3(c) above does not constitute a permitted distribution event under Section 409A(a)(2)(v) of the Code and the regulations thereunder, and where Section 409A of the Code applies to such distribution, then notwithstanding anything herein to the contrary, the cash payment will be made to you, to the extent necessary to comply with Section 409A of the Code, at the time specified in Section 8(a). In addition, for the avoidance of doubt, Section 18(c) of the Plan applies to any payment made pursuant to this Agreement.

9.Non-Assignability. The Performance Units are personal to you and are not transferable by you other than by will or the laws of descent and distribution. Any purported transfer or encumbrance in violation of the provisions of this Section 9 shall be void, and the other party to any such purported transaction shall not obtain any right to or interest in such Performance Units.

10.Miscellaneous.

(a)Construction. The contents of this Agreement are subject in all respects to the terms and conditions of the Plan as approved by the Board and the shareholders of Avient, which are controlling. The interpretation and construction by the Board and/or the Committee of any provision of the Plan or this Agreement shall be final and conclusive upon you, your estate, executor, administrator, beneficiaries, personal representative and guardian and Avient and its successors and assigns.

(b)Leave of Absence. Any absence or leave approved by a duly constituted officer of Avient or any of its Subsidiaries will not be considered an interruption or termination of your service under this Agreement.

(c)Data Privacy. The grant of the Performance Units is discretionary and will not be considered to be an employment contract or a part of your terms and conditions of employment or of your salary or compensation. Information about you and your participation in the Plan, including, without limitation, your name, home address, email address and telephone number, date of birth, social

2026 PU Award Agreement (US)

insurance number, passport number or other identification number, salary, nationality, job title, any shares of stock or directorships held in Avient, and details of the Performance Units or other entitlement to shares of stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in your favor may be collected, recorded, held, used and disclosed by Avient and any of its Subsidiaries and any non-Avient entities engaged by Avient to provide services in connection with this grant (a “Third Party Administrator”), for any purpose related to the administration of the Plan. You understand that Avient and its Subsidiaries may transfer such information to Third Party Administrators, regardless of whether such Third Party Administrators are located within your country of residence.

(d)Amendment. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto. The terms and conditions of this Agreement may not be modified, amended or waived, except by an instrument in writing signed by a duly authorized executive officer at Avient. Notwithstanding the foregoing, no amendment shall adversely affect your rights under this Agreement without your consent.

(e)No Modifications to Existing Agreements. Except as specifically referenced herein, nothing in this Agreement impacts, changes, or otherwise modifies any existing agreements between you and Avient.

(f)Clawback. Notwithstanding anything in this Agreement to the contrary, you acknowledge and agree that (i) this Agreement, the Performance Units (and any settlement thereof) and any other performance-based incentive compensation or related amounts held or received by you are subject to any Avient clawback policy applicable to you, under their terms and conditions as may be in effect from time to time, including, without limitation, to implement Section 10D of the Exchange Act and any applicable rules or regulations (including applicable rules and regulations of any national securities exchange or national securities association on which the Common Shares may be traded) (the “Compensation Recovery Policy”), and (ii) that any relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of any such clawback policy from and after the effective date thereof. Further, by accepting the Performance Units covered by this Agreement, you (A) consent to be bound by the terms of the Compensation Recovery Policy, as applicable, (B) agree and acknowledge that you are obligated to and will cooperate with, and will provide any and all assistance necessary to, Avient in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Avient policy, and (C) agree that Avient may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy. Such cooperation and assistance shall include (but is not limited to) executing, completing and

2026 PU Award Agreement (US)

submitting any documentation necessary, or consenting to action by Avient, to facilitate the recovery or recoupment by Avient from you of any such compensation or other amounts, including from your accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

(g)Investigations. Notwithstanding anything to the contrary in this Agreement or in any other agreement, contract or arrangement with Avient or a Subsidiary, or in any policy, procedure or practice of Avient or a Subsidiary (collectively, the “Arrangements”), (i) nothing in the Arrangements or otherwise limits your right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002), and (ii) nothing in the Arrangements or otherwise prevents you from, without prior notice to Avient, providing information (including documents) to governmental authorities or agencies regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities or agencies regarding possible legal violations, and for purposes of clarity you are not prohibited from providing information (including documents) voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act. Avient nonetheless asserts and does not waive its attorney-client privilege over any information appropriately protected by privilege. The terms of this Section 8(g) are referred to as the “Protected Rights,” and the terms of this Agreement are subject to the Protected Rights.

11.Notice. All notices under this Agreement to Avient must be delivered personally or mailed to Avient Corporation at Avient Center, 33587 Walker Road, Avon Lake, Ohio 44012, Attention: Corporate Secretary.

The effect of changes in tax law, accounting principles or other such laws or provisions affecting reported results or the effect of adverse determinations by regulatory agencies relating to accounting principles or treatment;

•Mark-to-market adjustments associated with actuarial gains and losses on pension and other postretirement benefit plans; and

•Special Items related to changes in portfolio as set forth below:

•Divestitures:

(c)“Relative Total Shareholder Return” or “rTSR” shall mean the percentile rank of Avient’s Total Shareholder Return with respect to the Performance Period as compared to (but not included in) the Total Shareholder Returns for all members of the Peer Group, ranked in descending order, at the end of the Performance Period.

(d)“Total Shareholder Return” shall mean, with respect to the Common Shares and the shares of common stock of each of the members of the Peer Group, a rate of return reflecting stock price appreciation, plus the reinvestment of dividends in additional shares of stock, from the beginning of the Performance Period through the end of the Performance Period. In general, Total Shareholder Return shall be determined for each of Avient and each Peer Group entity as a percentage (rounded to the nearest two decimal places) based on the quotient of (i) the sum of (A) the difference between the Ending Average (as defined below) and the Beginning Average (as defined below) plus (B) dividends, divided by (ii) the Beginning Average. For purposes of calculating Total Shareholder Return for Avient and the members of the Peer Group, the beginning stock price will be based on the average closing price for the 20 trading days preceding the first day of the Performance Period on the principal stock exchange on which the stock is then traded (the “Beginning Average”), and the ending stock price will be based on the average closing price for the 20 trading days preceding and including the last day of the Performance Period (the “Ending Average”).

2. Peer Group Adjustments. The following adjustments will be made to the Peer Group during the Performance Period:

(a)If any member of the Peer Group (i) files for bankruptcy, reorganization, or liquidation under any chapter of the U.S. Bankruptcy Code or similar non-U.S. law (collectively, “bankruptcy”), (ii) is the subject of an involuntary bankruptcy proceeding that is not dismissed within 30 days, (iii) is the subject of a stockholder-approved plan of liquidation or dissolution or makes a general assignment for the benefit of creditors, or (iv) ceases to conduct substantial business operations (provided that, for the avoidance of doubt, (A) the acquisition of a member of the Peer Group by another person or group of related persons by itself does not result in the company being treated as ceasing to conduct substantial business operations, (B) any acquisition by an unaffiliated person or group of related persons shall be subject to Section 2(b) below, and (C) treatment under this Section 2(a) shall not be affected by any subsequent reorganization, recapitalization

2026 PU Award Agreement (US)

or other restructuring pursuant to which the entity emerges from bankruptcy or otherwise continues or re-commences operations), then such entity will remain in the Peer Group, but Relative Total Shareholder Return for the Performance Period will be calculated as if such entity achieved Total Shareholder Return, placing it at the bottom (chronologically, if more than one such entity) of the Peer Group;

(b)If, by the end of the Performance Period, any member of the Peer Group has been acquired by an unaffiliated person or group of persons or is otherwise no longer existing as a publicly-traded company (other than for the reasons as described in Section 2(a) above), then such entity will be removed from the Peer Group; and

AVIENT CORPORATION INCENTIVE AWARD

Grant of Restricted Stock Units

Subject to the terms and conditions of the Avient Corporation 2020 Equity and Incentive Compensation Plan, as amended and restated effective May 11, 2023 (the “Plan”), and this letter agreement (this “Agreement”), the Compensation Committee of the Board of Directors (the “Committee”) of Avient Corporation (“Avient”) has granted to you, as of #GrantDate#, the following award:

#QuantityGranted# restricted stock units (the “Restricted Stock Units”), which shall vest in accordance with the terms set forth in this Agreement. Each Restricted Stock Unit shall represent one hypothetical common share, par value US$0.01 per share, of Avient (a “Common Share”) and shall at all times be equal in value to one Common Share.

Copies of the Plan and the Plan Prospectus, as supplemented, are available for your review through the Corporate Secretary’s office. Unless otherwise indicated, the capitalized terms used in this Agreement shall have the same meanings as set forth in the Plan.

1.Vesting of Restricted Stock Units.

(a)Normal Vesting. Subject to the provisions of the Plan and this Agreement, the Restricted Stock Units shall vest in substantially equal installments on each of the following dates: #VestDate_1#, #VestDate_2# and #VestDate_3# (each date, a “Vesting Date”, and the three-year vesting period from #GrantDate# until #VestDate_3#, the “Restriction Period”), provided that you remain in the continuous employ of Avient or a Subsidiary on each such Vesting Date.

(b)Disability or Death. Notwithstanding the provisions of Section 1(a) of this Agreement, if your employment with Avient or a Subsidiary terminates prior to

2026 RSU Award Agreement (Canada)

NAI-5010401600v2

the end of the Restriction Period due to (i) your permanent and total disability (as defined under the relevant disability plan or program of Avient or a Subsidiary in which you then participate, or if there is no such plan or program, such condition provided in any applicable governmental statute or regulation that constitutes a disability, or if there is no such applicable statute or regulation, such other condition as may be determined by the Committee in its sole discretion to constitute a disability) or (ii) your death, you shall vest in a number of Restricted Stock Units equal to the product of (A) one-third of the total number of Restricted Stock Units subject to this Agreement, multiplied by (B) a fraction, the numerator of which is the number of days that have elapsed between the Vesting Date immediately preceding your termination date (or, in the event your employment terminates prior to the first Vesting Date, #GrantDate#) and the date your employment by Avient or a Subsidiary terminates, and the denominator of which is 365 (or 366, if your employment terminates in 2028). The remaining portion of the Restricted Stock Units will be forfeited.

(c)Retirement. Notwithstanding the provisions of Sections 1(a) and 1(b) of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the end of the Restriction Period due to (i) your retirement at age 55 or older with at least 10 years of service (“55+ Retirement”) or (ii) your retirement at age 58 or older with at least 5 years of service (“58+ Retirement”), you shall vest in all of the Restricted Stock Units that remain unvested as of the date of your 55+ Retirement or 58+ Retirement, as applicable.

(d)Termination without Cause Prior to a Change of Control. Notwithstanding the provisions of Sections 1(a), 1(b) and 1(c), if your employment with Avient or a Subsidiary is terminated by Avient or a Subsidiary without Cause (as defined in Section 1(f)(i) below) prior to the end of the Restriction Period and prior to a Change of Control in the circumstances described below, any Restricted Stock Units that remain unvested as of such termination shall vest as follows:

(i)If, as of the date of your termination without Cause (as defined in Section 1(f)(i)), (A) you have been designated as an officer for purposes of Section 16 of the Exchange Act (a “Section 16 Officer”) for at least two consecutive years immediately prior to such date and are not eligible for a 55+ Retirement or a 58+ Retirement (“Retirement Eligible”) or (B) you have not been designated a Section 16 Officer for at least two consecutive years immediately prior to such date and you are Retirement Eligible, you shall vest on the date of your termination without Cause in a number of Restricted Stock Units equal to the product of (I) one-third of the total number of Restricted Stock Units subject to this Agreement, multiplied by (II) a fraction, the numerator of which is the number of days that have elapsed between the Vesting Date immediately preceding your termination date (or, in the event your employment terminates prior to the first Vesting Date, #GrantDate#) and the date your employment by Avient or a Subsidiary terminates, and the denominator of which is 365 (or 366, if your employment terminates in 2028). Any remaining portion of the Restricted Stock Units will be forfeited.

(ii)If, as of the date of your termination without Cause (as defined in Section 1(f)(i)), you have been designated a Section 16 Officer for more than two consecutive years immediately prior to such date and are Retirement Eligible, you shall vest on the date of your termination without Cause in all of the Restricted Stock Units that remain unvested as of such date.

NAI-5010401600v2

(e)Change of Control. Notwithstanding the provisions of Sections 1(a), 1(b), 1(c) and 1(d) of this Agreement, if a Change of Control occurs prior to the end of the Restriction Period and you remain in the continuous employ of Avient or a Subsidiary, any Restricted Stock Units that remain unvested as of such Change of Control shall vest as follows:

(i)notwithstanding anything to the contrary herein, except to the extent that a Replacement Award is provided to you in accordance with Section 1(e)(ii) to continue, replace or assume the Restricted Stock Units covered by this Agreement (the “Replaced Award”), all of the unvested Restricted Stock Units shall vest on the date of such Change of Control.

(ii)for purposes of this Agreement, a “Replacement Award” means an award (A) of the same type (e.g., time-based restricted stock units) as the Replaced Award, (B) that has a value at least equal to the value of the Replaced Award, (C) that relates to publicly traded equity securities of Avient or its successor in the Change of Control or another entity that is affiliated with Avient or its successor following the Change of Control (the “Successor”), (D) if you are subject to U.S. federal income tax under the Code, the tax consequences of which under the Code are not less favorable than the tax consequences of the Replaced Award, (E) that vests in full upon a termination of your employment with Avient, a Subsidiary or the Successor without Cause (as defined in Section 1(f)(ii) below) by Avient, a Subsidiary or the Successor or by you for Good Reason (as defined in Section 1(f)(iii) below), in either case within a period of two years after the Change of Control, and (F) the other terms and conditions of which are not less favorable to you than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change of Control).  A Replacement Award may be granted only to the extent it does not result in the Replaced Award or Replacement Award failing to comply with or be exempt from Section 409A of the Code.  Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the two preceding sentences are satisfied.  The determination of whether the conditions of this Section 1(e)(ii) are satisfied will be made by the Committee, as constituted immediately before the Change of Control, in its sole discretion.

(iii)if, after receiving a Replacement Award and within a period of two years after the Change of Control, (A) your employment is terminated without Cause (as defined in Section 1(f)(ii) below) by Avient, a Subsidiary or the Successor, as applicable, or (B) you terminate your employment with Avient, a Subsidiary or the Successor, as applicable, for Good Reason (as defined in Section 1(f)(iii) below), the Replacement Award, to the extent it remains unvested, shall become fully vested with respect to the time-based restricted stock units covered by such Replacement Award upon such termination.

(iv)if a Replacement Award is provided, notwithstanding anything in this Agreement to the contrary, any outstanding Restricted Stock Units subject to this Agreement that at the time of the Change of Control are not subject to a “substantial risk of forfeiture” (within the meaning of Section 409A of the Code) will be deemed to be vested at the time of such Change of Control.

2026 RSU Award Agreement (Canada)

NAI-5010401600v2

(f)For purposes of this Agreement:

(i)in the event of a termination of your employment without Cause pursuant to Section 1(d) of this Agreement, “Cause” shall mean (A) your serious violation or deliberate disregard of Avient or a Subsidiary’s policies; (B) your gross dereliction in the performance of your job duties and responsibilities; (C) your violation of Avient’s Code of Conduct or any successor document; (D) your misappropriation of property of Avient or a Subsidiary; (E) your commission of an act of fraud upon, or bad faith, dishonesty or disloyalty toward Avient or any of its Subsidiaries; (F) your breach of any restrictive covenants or written obligations to Avient or a Subsidiary in respect of confidentiality and/or the use or ownership of proprietary information; (G) an event of egregious misconduct involving serious moral turpitude to the extent that, in the reasonable judgment of the Committee, your credibility and reputation no longer conforms to the standards applicable to Avient’s executives; or (H) an act or omission that Avient reasonably determines may prejudice significantly its best interests if your employment is not terminated.

(ii)in the event of a termination of your employment without Cause following a Change of Control pursuant to Section 1(e) of this Agreement, “Cause” shall mean (A) the willful and continued failure by you to substantially perform your duties with Avient or any Subsidiary, which failure causes material and demonstrable injury to Avient or any Subsidiary (other than any such failure resulting from your incapacity due to physical or mental illness), after a demand for substantial performance is delivered to you by the Committee or the Board which specifically identifies the manner in which the Committee or the Board believes that you have not substantially performed your duties, and after you have been given a period of at least 30 days to correct your performance, or (B) the willful engaging by you in other gross misconduct materially and demonstrably injurious to Avient or a Subsidiary. For purposes of this Section 1(f)(ii), no act or failure to act, on your part shall be considered “willful” unless conclusively demonstrated to have been done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interests of Avient or a Subsidiary.

(iii)“Good Reason” shall mean (A) a material diminution in your duties or responsibilities at Avient or a Subsidiary; (B) a material reduction in your base salary, other than a reduction or failure that is part of a broad reduction in base salary generally applicable to Avient’s other similarly-situated employees; (C) your permanent reassignment to another primary work location more than 50 miles from your then-current work location; or (D) a material breach by Avient or a Subsidiary of any obligation under any material agreement between you and Avient or a Subsidiary; provided, that no later than 30 days following an event constituting Good Reason, you give notice to Avient or a Subsidiary of the occurrence of such event, Avient or a Subsidiary fails to remedy the event within 30 calendar days after receipt of such written notice and your employment is terminated within 60 days thereafter.

(g)Notwithstanding the provisions of Sections 1(a), 1(b), 1(c), 1(d) and 1(e) of this Agreement and to the extent permitted by applicable law, a number of Restricted Stock Units may vest and become payable prior to a Vesting Date or other vesting

2026 RSU Award Agreement (Canada)

NAI-5010401600v2

event described in Sections 1(b), 1(c), 1(d) and 1(e) of this Agreement in an amount that is sufficient to cover any employment tax that becomes payable by you with respect to the Restricted Stock Units prior to such Vesting Date or other vesting event, as applicable.

2.Other Termination.

(a)If your employment with Avient or a Subsidiary terminates before the end of the Restriction Period for any reason other than as set forth in Section 1(b), Section 1(c), Section 1(d) or Section 1(e)(iii) of this Agreement, all of the Restricted Stock Units that remain unvested as of the termination of your employment will be forfeited. For the avoidance of doubt, such reasons shall include, without limitation, a termination of your employment with Avient or a Subsidiary for Cause (as defined in Section 1(f)(i) or Section 1(f)(ii), as applicable, depending on whether a termination of your employment occurs prior to or following a Change of Control), regardless of whether you are Retirement Eligible at such time.

(b)For purposes of this Agreement, the date of occurrence of your termination of employment by Avient or a Subsidiary is the date that you actually cease to perform services for Avient or a Subsidiary, without regard to whether (i) you continue thereafter to receive any payment from Avient or a Subsidiary in respect of such termination, including, without limitation, any continuation of salary or other compensation in lieu of notice of such termination, or (ii) you claim or are found to be entitled at law to greater notice of such termination or greater compensation in lieu thereof than you have received from Avient or a Subsidiary.

3.Payment of Restricted Stock Units.

(a)The Restricted Stock Units that vest pursuant to Section 1 of this Agreement will be paid in Common Shares transferred to you within 30 business days following the applicable Vesting Date; provided, however, that, subject to Section 3(b) of this Agreement, the Restricted Stock Units that vest in accordance with Section 1(b), 1(c), 1(d), 1(e)(i) or 1(e)(iii) of this Agreement will be paid within 30 business days following the date of the termination of your employment or the date of the Change of Control, whichever applies.

(b)To the extent applicable, if the event triggering the right to payment under Section 3(a) of this Agreement does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything herein to the contrary, the payment of Common Shares will be made to you, to the extent necessary to comply with Section 409A of the Code, on the earliest of (i) your “separation from service” with Avient or a Subsidiary (determined in accordance with Section 409A of the Code) that occurs after the event giving rise to payment; (ii) the Vesting Date applicable to the Restricted Stock Units attributable to such Common Shares; or (iii) your death. In addition, for the avoidance of doubt, Section 18(c) of the Plan applies to any payment of Common Shares made pursuant to this Agreement.

4.Dividend, Voting and Other Rights. You shall have no rights of ownership in the Restricted Stock Units or the Common Shares underlying the Restricted Stock Units and you shall have no right to vote the underlying Common Shares until the date on which any Common Shares are transferred to you pursuant to Section 3 of this Agreement. While the Restricted Stock Units are still outstanding, on the record date for each cash dividend, if any, that Avient pays to holders of Common Shares generally (the “Record

2026 RSU Award Agreement (Canada)

NAI-5010401600v2

Date”), you shall be entitled to a number of additional whole Restricted Stock Units determined by dividing (a) the product of (i) the dollar amount of the cash dividend paid per Common Share and (ii) the total number of Restricted Stock Units (including dividend equivalents paid thereon) credited to you as of the Record Date, by (b) the Market Value per Share on the Record Date. Any dividend equivalents credited hereunder shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the Restricted Stock Units to which the dividend equivalents were credited.

5.Non-Assignability. The Restricted Stock Units are personal to you and are not transferable by you other than by will or the laws of descent and distribution. Any purported transfer or encumbrance in violation of the provisions of this Section 5 shall be void, and the other party to any such purported transaction shall not obtain any right to or interest in such Restricted Stock Units.

6.Adjustments. In the event of any extraordinary cash dividend, stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of Avient, merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial or complete liquidation or other distribution of assets, issuance of rights or warrants to purchase securities, or any other corporate transaction or event having an effect similar to any of the foregoing, the Committee shall make or provide for such adjustments in the number of and kind of Common Shares covered by the Restricted Stock Units then held by you, and in other award terms, as the Committee, in its sole discretion, exercised in good faith, determines is equitably required to prevent dilution or enlargement of your rights in connection with such transaction or event. If any such transaction or event occurs or in the event of a Change of Control, the Committee may provide in substitution for outstanding Restricted Stock Units such alternative consideration (including, without limitation, in the form of cash, securities or other property) as it may determine to be equitable in the circumstances and shall require in connection therewith the surrender of the Restricted Stock Units subject to this Agreement. No adjustment provided for in this Section 6 or Section 12 of the Plan will require Avient to issue any fractional shares.

7.Responsibility for Taxes.

(a)Regardless of any action Avient or your employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax related withholdings (“Tax Related Items”), you acknowledge that the ultimate liability for all Tax Related Items legally due by you is and remains your responsibility and that Avient and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax Related Items in connection with any aspect of the Restricted Stock Units grant, including the grant or vesting of the Restricted Stock Units, and the receipt of any dividends or dividend equivalents, and (ii) do not commit to structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or eliminate your liability for Tax Related Items.

(b)To the extent that Avient or the Employer is required to withhold taxes in accordance with applicable law in connection with the vesting of your Restricted Stock Units, Avient or the Employer shall withhold from the total number of Common Shares that you are to receive upon settlement a number of shares that has a total value equal to the amount necessary to satisfy any and all such withholding tax obligations. The value of any fraction of retained Common Shares not necessary for required withholding shall be applied to your income tax withholding by your Employer generally. Instead of withholding Common

2026 RSU Award Agreement (Canada)

NAI-5010401600v2

Shares as described above, (i) you may be required to remit to your Employer on the date on which you become the owner of Common Shares under this Agreement cash in an amount sufficient to satisfy all applicable required withholding taxes and social security contributions related to the Common Shares, or (ii) to the extent permitted by local law, the Employer may deduct from your regular salary payroll cash, on a payroll date following the date on which you become the owner of Common Shares under this Agreement, in an amount sufficient to satisfy such obligations.

8.Miscellaneous.

(a)Construction. The contents of this Agreement are subject in all respects to the terms and conditions of the Plan as approved by the Board and the shareholders of Avient, which are controlling. The interpretation and construction by the Board and/or the Committee of any provision of the Plan or this Agreement shall be final and conclusive upon you, your estate, executor, administrator, beneficiaries, personal representative and guardian and Avient and its successors and assigns.

(b)Leave of Absence. Any absence or leave approved by a duly constituted officer of Avient or any of its Subsidiaries will not be considered an interruption or termination of your service under this Agreement.

(c)Discretionary Grant; Future Value Unknown. The grant of the Restricted Stock Units is voluntary and discretionary and is being made on a one-time basis, and does not constitute a commitment to make any future awards. Furthermore, the grant will not be considered to be an employment contract and will not be considered salary or other compensation for purposes of any severance pay or similar allowance, except as otherwise required by law. In addition, the future value of any Common Shares acquired upon exercise or settlement is unknown and cannot be predicted with certainty.

(d)Data Privacy. Information about you and your participation in the Plan, including, without limitation, your name, home address, email address and telephone number, date of birth, social insurance number, passport number or other identification number, salary, nationality, job title, any shares of stock or directorships held in Avient, and details of the Restricted Stock Units or other entitlement to shares of stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in your favor (“Data”) may be collected, recorded, held, used and disclosed by Avient, which is located in the United States, and any of its Subsidiaries and any non-Avient entities engaged by Avient to provide services in connection with this grant (a “Third Party Administrator”), for any purpose related to the administration of the Plan.

NON-U.S. ADDENDUM

Additional Terms and Conditions for Grant of Restricted Stock Units

February 2026

Terms and Conditions

This Non-U.S. Addendum (this “Non-U.S. Addendum”) includes additional terms and conditions that govern the Restricted Stock Units granted to you under the Avient Corporation 2020 Equity and Incentive Compensation Plan, as amended and restated effective May 11, 2023 (the “Plan”), if you reside in Canada. Certain capitalized terms used but not defined in this Non-U.S. Addendum have the meanings set forth in the Plan and/or your award agreement that relates to your award (the “Agreement”). By accepting your award, you agree to be bound by the terms and conditions contained in the paragraphs below in addition to the terms of the Plan, the Agreement, and the terms of any other document that may apply to you and your award.

Notifications

This Non-U.S. Addendum also includes information regarding exchange controls and certain other issues of which you should be aware with respect to participation in the Plan. The information is based on the securities, exchange control, and other laws in effect in Canada as of February 2026. Such laws are often complex and change frequently. As a result, it is strongly recommended that you not rely on the information in this Non-U.S. Addendum as the only source of information relating to the consequences of your participation in the Plan because the information may be out of date at the time your Restricted Stock Units vest or you sell Common Shares acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to your particular situation, and Avient Corporation (“Avient”) is not in a position to assure you of a particular result. Accordingly, you are advised to seek appropriate professional advice as to how the relevant laws in your country may apply to your situation.

Terms and Conditions

Other Termination. Sections 2(a) and 2(b) of the Agreement are hereby amended and replaced in their entirety to read as follows:

“(a)    If your employment with Avient or a Subsidiary terminates before the end of the Restriction Period for any reason other than as set forth in Section 1(b), Section 1(c), Section 1(d) or Section 1(e)(iii) of this Agreement, all of the Restricted Stock Units that remain unvested as of the termination of your employment will be forfeited, except to the extent otherwise expressly required to comply with minimum standards employment legislation, if applicable, in Canada. For the avoidance of doubt, such reasons shall include, without limitation, a termination of your employment with Avient or a Subsidiary for Cause (as defined in Section 1(f)(i) or Section 1(f)(ii), as applicable, depending on whether a termination of your employment occurs prior to or following a Change of Control), regardless of whether you are Retirement Eligible at such time.

(b)    For purposes of this Agreement, the date of occurrence of your termination of employment by Avient or a Subsidiary is the later of: (i) the date that you actually cease to perform services for Avient or a Subsidiary, as recorded by Avient or its Subsidiary, as applicable; and (i) the last day of the period during which you are entitled to notice of termination under applicable minimum employment standards legislation (the “Termination Date”).

For greater certainty, the Termination Date shall be determined without reference to any statutory severance or any contractual or common law notice of termination of which you are in receipt or may be eligible to receive at common law, pursuant to a contract, or otherwise; and no grants or damages in lieu thereof are payable with respect to any applicable statutory severance period or contractual or common law notice period. Notwithstanding the foregoing, in no event will you receive less under this Agreement than that required by applicable minimum employment standards legislation.

Avient and its Subsidiaries reserve the right to terminate the employment of any person, regardless of the effect of such termination of employment on entitlements under this Agreement. You hereby waive, and irrevocably release Avient and its Subsidiaries from, any claim or entitlement to compensation or damages that may arise from any forfeiture of the Restricted Stock Units as a result of the cessation of vesting on the Termination Date.”

Governing Law. Section 13 of the Agreement is hereby amended to add the following sentence to the end thereof to read as follows:

“Nothing in this Section 13 affects your right to pursue statutory relief available in your jurisdiction where such right cannot be waived under applicable law.”

Restricted Stock Units Settled in Shares Only. Notwithstanding anything to the contrary in the Plan and/or the Agreement, you understand that any Restricted Stock Units granted to you shall be paid in Common Shares only and do not provide any right for you to receive a cash payment.

Notifications

Additional Restrictions on Resale. In addition to the restrictions on resale and transfer noted in Plan materials, securities purchased under the Plan may be subject to certain restrictions on resale imposed by Canadian provincial securities laws. You are encouraged to seek legal advice prior to any resale of such securities. In general, participants residing in Canada may resell their securities in transactions carried out on exchanges outside of Canada and, in particular, you are generally permitted to sell Common Shares acquired pursuant to the Plan through the designated broker appointed under the Plan, if any, provided that Avient is a “foreign issuer” that is not a reporting issuer in any jurisdiction of Canada and the sale of the Common Shares acquired pursuant to the Plan takes place: (i) through an exchange, or a market, outside of Canada on the distribution date; or (ii) to a person or company outside of Canada. For purposes hereof, a “foreign issuer” is an issuer that: (a) is not incorporated or existing pursuant to the laws of Canada or any jurisdiction of Canada; (b) does not have its head office in Canada; and (c) does not have a majority of its executive officers or directors ordinarily resident in Canada.

Form of Payment. Due to legal restrictions in Canada and notwithstanding any language to the contrary in the Plan, you are prohibited from surrendering shares that you already own or from attesting to the ownership of shares to pay any tax withholding in connection with the Restricted Stock Units granted. Any tax withholding must be paid in cash or by check or by wire transfer of immediately available funds, by a combination of such methods of payment, or by such other methods as may be approved by the Board.

Tax Reporting. The Income Tax Act (Canada) (the “Tax Act”) and the regulations thereunder require an investor that is a “specified Canadian entity” to file an information return disclosing prescribed information where, at any time in a taxation year, the total cost amount of “specified foreign property” of the entity exceeds Cdn.$100,000. For these purposes, a “specified Canadian

3    Non-U.S. Addendum (Canada) (RSU)

NAI-5010402711v2

entity” includes a taxpayer resident in Canada that is not, among other things, a corporation or trust exempt from tax under Part I of the Tax Act. The Common Shares are “specified foreign property”. The reporting rules in the Tax Act are complex and this summary does not purport to explain all circumstances in which reporting may be required by any investor. You should consult your own tax advisor regarding these reporting requirements.

1.Performance Units.

(a)Subject to the provisions of the Plan and this Agreement, your right to receive all or any portion of the Performance Units will be contingent upon the achievement of certain management objectives (the “Management Objectives”), as set forth in your Statement of Performance Goals. The achievement of the Management Objectives will be measured with respect to the period beginning on January 1, 2026 and ending on December 31, 2028 (the “Performance Period”).

2026 PU Award Agreement (Canada)

(b)Sixty-seven percent (67%) of the Performance Units (the “EPS Performance Units”) will be earned based solely on achievement of performance goals relating to Avient’s Adjusted Earnings per Share (“Adjusted EPS”), as defined in your Statement of Performance Goals, and the remaining thirty-three percent (33%) of the Performance Units (the “rTSR Performance Units”) will be earned based solely on achievement of performance goals relating to Avient’s Relative Total Shareholder Return (“rTSR”), as defined in your Statement of Performance Goals.

2.Earning of Performance Units.

(a)EPS Performance Units. The EPS Performance Units may be earned as follows:

(i)Threshold. If, upon the conclusion of the Performance Period, Adjusted EPS equals the threshold level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 50% of the EPS Performance Units shall become earned.

(ii)Target. If, upon the conclusion of the Performance Period, Adjusted EPS equals the target level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 100% of the EPS Performance Units shall become earned.

(iii)Equals or Exceeds Maximum. If, upon the conclusion of the Performance Period, Adjusted EPS equals or exceeds the maximum level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 200% of the EPS Performance Units shall become earned.

(iv)Between Threshold and Target or Target and Maximum. If, upon the conclusion of the Performance Period, Adjusted EPS is greater than the threshold level, but less than the target level, or greater than the target level, but less than the maximum level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then a proportionate percentage of the EPS Performance Units shall become earned, as determined by mathematical interpolation and rounded up to the nearest whole unit.

(v)Below Threshold. In no event shall any EPS Performance Units become earned if actual performance for the Performance Period falls below the threshold level for Adjusted EPS or if the Committee does not certify that the Management Objectives have been satisfied with respect to the EPS Performance Units for the Performance Period.

(b)rTSR Performance Units. The rTSR Performance Units may be earned as follows:

(i)Threshold. If, upon the conclusion of the Performance Period, rTSR equals the threshold level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then 50% of the rTSR Performance Units shall become earned.

(iii)Equals or Exceeds Maximum. If, upon the conclusion of the Performance Period, rTSR equals or exceeds the maximum level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then 200% of the rTSR Performance Units shall become earned.

If, upon the conclusion of the Performance Period, rTSR is greater than the threshold level, but less than the target level, or greater than the target level, but less than the maximum level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then a proportionate percentage of the rTSR Performance Units shall become earned, as determined by mathematical interpolation and rounded up to the nearest whole unit.

(v)Below Threshold. In no event shall any rTSR Performance Units become earned if actual performance for the Performance Period falls below the threshold level for rTSR or if the Committee does not certify that the Management Objectives have been satisfied with respect to the rTSR Performance Units for the Performance Period.

(c)If the Committee determines that a change in the business, operations, corporate structure or capital structure of Avient, the manner in which it conducts business or other events or circumstances render the Management Objectives to be unsuitable, the Committee may modify such Management Objectives or the related levels of achievement, in whole or in part, as the Committee deems appropriate.

(d)Subject to the provisions of Sections 3, 4, 5 and 6 of this Agreement, your right to receive any Performance Units is contingent upon your remaining in the continuous employ of Avient or a Subsidiary through the payment date, which shall be a date in 2029 determined by the Committee (or its authorized delegatee) and shall occur no later than March 15, 2029 (the “Payment Date”).

(e)Notwithstanding the provisions of Section 4, 5 or 6 of this Agreement and to the extent permitted by applicable law, a number of Performance Units may become non-forfeitable and payable prior to the Payment Date in an amount that is sufficient to cover any employment tax that becomes payable by you with respect to the Performance Units prior to the Payment Date.

3.Change of Control. Subject to Section 8,

(a)if a Change of Control occurs prior to the Payment Date or forfeiture of the Performance Units and while you remain in the continuous employ of Avient or a Subsidiary, then, except to the extent that a Replacement Award is provided to you in accordance with Section 3(b) of this Agreement to continue, replace or assume the Performance Units covered by this Agreement (the “Replaced Award”), the number of Performance Units under this Agreement that shall be

2026 PU Award Agreement (Canada)

deemed fully earned shall equal the greater of (i) the target number of Performance Units granted pursuant to this Agreement; and (ii) the number of Performance Units earned based on the achievement of the performance measures specified in your Statement of Performance Goals as if the date of the Change of Control had been the last day of the Performance Period (as determined by the Committee as constituted immediately prior to the Change of Control) (but in no event may negative discretion be exercised with respect to the number of Performance Units earned). Any Performance Units that are not earned in accordance with the foregoing sentence shall terminate and be forfeited.

(b)for purposes of this Agreement, a “Replacement Award” means an award: (i) consisting of an award of performance units; (ii) that has a value at least equal to the value of the Replaced Award; (iii) that relates to publicly traded equity securities of Avient or its successor in the Change of Control or another entity that is affiliated with Avient or its successor following the Change of Control (the “Successor”); (iv) if you are subject to U.S. federal income tax under the Code, the tax consequences of which under the Code are not less favorable than the tax consequences of the Replaced Award; (v) that vests upon a termination of your employment with Avient, a Subsidiary or the Successor for Good Reason (as defined in Section 3(d)(ii) below) or without Cause (as defined in Section 3(d)(i) below) by Avient, a Subsidiary or the Successor, in each case within a period of two years after the Change of Control based on actual performance through the date of such termination; and (vi) the other terms and conditions of which are not less favorable to you than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change of Control).  A Replacement Award may be granted only to the extent it does not result in the Replaced Award or Replacement Award failing to comply with or be exempt from Section 409A of the Code.  Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the two preceding sentences are satisfied.  The determination of whether the conditions of this Section 3(b) are satisfied will be made by the Committee, as constituted immediately before the Change of Control, in its sole discretion.

(c)if a Replacement Award is provided, (i) the terms of the Replacement Award will govern the vesting and payment of the Replacement Award; and (ii) notwithstanding anything in this Agreement to the contrary, any outstanding Performance Units subject to this Agreement that at the time of the Change of Control are not subject to a “substantial risk of forfeiture” (within the meaning of Section 409A of the Code) will be deemed fully earned at the time of such Change of Control and will be paid as provided in Section 8(b) of this Agreement.

(d)For purposes of this Section 3:

(i)“Cause” shall mean (A) the willful and continued failure by you to substantially perform your duties with Avient or any Subsidiary, which failure causes material and demonstrable injury to Avient or any Subsidiary (other than any such failure resulting from your incapacity due to physical or mental illness), after a demand for substantial performance is delivered to you by the Committee or the Board which specifically

2026 PU Award Agreement (Canada)

identifies the manner in which the Committee or the Board believes that you have not substantially performed your duties, and after you have been given a period of at least 30 days to correct your performance, or (B) the willful engaging by you in other gross misconduct materially and demonstrably injurious to Avient or a Subsidiary. For purposes of this Section 3(d)(i), no act or failure to act, on your part shall be considered “willful” unless conclusively demonstrated to have been done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interests of Avient or a Subsidiary.

(ii)“Good Reason” shall mean (A) a material diminution in your duties or responsibilities at Avient or a Subsidiary; (B) a material reduction in your base salary, other than a reduction or failure that is part of a broad reduction in base salary generally applicable to Avient’s other similarly-situated employees; (C) your permanent reassignment to another primary work location more than 50 miles from your then- current work location; or (D) a material breach by Avient or a Subsidiary of any obligation under any material agreement between you and Avient or a Subsidiary; provided, that no later than 30 days following an event constituting Good Reason, you give notice to Avient or a Subsidiary of the occurrence of such event, Avient or a Subsidiary fails to remedy the event within 30 calendar days after receipt of such written notice and your employment is terminated within 60 days thereafter.

4.Disability or Death. Subject to Section 8 of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the Payment Date and, to the extent a Replacement Award is not granted, prior to a Change of Control due to (a) permanent and total disability (as defined under the relevant disability plan or program of Avient or a Subsidiary in which you then participate, or if there is no such plan or program, such condition provided in any applicable governmental statute or regulation that constitutes a disability, or if there is no such applicable statute or regulation, such other conditions as may be determined by the Committee in its sole discretion to constitute a disability) or (b) death, Avient shall pay to you or your executor or administrator, as the case may be, on the Payment Date, the product of (i) the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period, multiplied by (ii) a fraction, the numerator of which is the number of days during the Performance Period commencing on the first day of the Performance Period and extending through the date of your termination pursuant to one of the events described in clause (a) or (b) above, and the denominator of which is 1,096.

5.Retirement. Subject to Section 8 of this Agreement, if your employment with Avient or a Subsidiary terminates prior to the Payment Date due to (a) your retirement at age 55 or older with at least 10 years of service (“55+ Retirement”) or (b) your retirement at age 58 or older with at least 5 years of service (“58+ Retirement”), Avient shall pay to you on the Payment Date the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the

2026 PU Award Agreement (Canada)

Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period.

6.Termination without Cause Prior to a Change of Control. Subject to Section 8 of this Agreement, if your employment with Avient or a Subsidiary is terminated by Avient or a Subsidiary without Cause (as defined in Section 6(c)) prior to the Payment Date and prior to a Change of Control, the Performance Units shall vest as follows:

(a)if, as of the date of your termination without Cause (as defined in Section 6(c)), (i) you have been designated as an officer for purposes of Section 16 of the Exchange Act (a “Section 16 Officer”) for at least two consecutive years immediately prior to such date and are not eligible for a 55+ Retirement or a 58+ Retirement (“Retirement Eligible”) or (ii) you have not been designated a Section 16 Officer for at least two consecutive years immediately prior to such date and you are Retirement Eligible, Avient shall pay to you on the Payment Date the product of (A) the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period, multiplied by (B) a fraction, the numerator of which is the number of days during the Performance Period commencing on the first day of the Performance Period and extending through the date of your termination without Cause, and the denominator of which is 1,096.

(b)if, as of the date of your termination without Cause (as defined in Section 6(c)), you have been designated a Section 16 Officer for more than two consecutive years immediately prior to such date and are Retirement Eligible, Avient shall pay to you on the Payment Date the actual number of Performance Units you would have earned as of the Payment Date pursuant to Section 2 of this Agreement with respect to the Performance Period had you remained in the continuous employ of Avient or a Subsidiary for the entirety of the Performance Period.

(c)for purposes of this Section 6, “Cause” shall mean (i) your serious violation or deliberate disregard of Avient or a Subsidiary’s policies; (ii) your gross dereliction in the performance of your job duties and responsibilities; (iii) your violation of Avient’s Code of Conduct or any successor document; (iv) your misappropriation of property of Avient or a Subsidiary; (v) your commission of an act of fraud upon, or bad faith, dishonesty or disloyalty toward Avient or any of its Subsidiaries; (vi) your breach of any restrictive covenants or written obligations to Avient or a Subsidiary in respect of confidentiality and/or the use or ownership of proprietary information; (vii) an event of egregious misconduct involving serious moral turpitude to the extent that, in the reasonable judgment of the Committee, your credibility and reputation no longer conforms to the standards applicable to Avient’s executives; or (viii) an act or omission that Avient reasonably determines may prejudice significantly its best interests if your employment is not terminated.

7.Other Termination.

(a)If your employment with Avient or a Subsidiary terminates before the Payment Date for any reason other than as set forth in Section 3, 4, 5 or 6 above, the

2026 PU Award Agreement (Canada)

Performance Units will be forfeited. For the avoidance of doubt, such reasons shall include, without limitation, a termination of your employment with Avient or a Subsidiary for Cause (as defined in Section 3(d)(i) or Section 6(c), as applicable, depending on whether a termination of your employment occurs prior to or following a Change of Control), regardless of whether you are Retirement Eligible at such time.

(b)For purposes of this Agreement, the date of occurrence of your termination of employment by Avient or a Subsidiary is the date that you actually cease to perform services for Avient or a Subsidiary, without regard to whether (i) you continue thereafter to receive any payment from Avient or a Subsidiary in respect of such termination, including, without limitation, any continuation of salary or other compensation in lieu of notice of such termination, or (ii) you claim or are found to be entitled at law to greater notice of such termination or greater compensation in lieu thereof than you have received from Avient or a Subsidiary.

8.Payment of Performance Units.

(a)Payment of any Performance Units that become earned as set forth herein will be made in the form of cash in the currency of the country in which you work at the time of payment. The amount of the cash payment to be made shall be determined by multiplying (i) the number of Performance Units earned pursuant to Section 2, 3, 4, 5 or 6 above by (ii) US$1.00, and will then be converted into your home currency using the balance sheet monthly exchange rate published by Avient’s Finance Department as of December 31st immediately preceding the Payment Date. Except as provided in Section 8(b) of this Agreement, payment will be made on the Payment Date.

(b)Notwithstanding Section 8(a), to the extent that the Performance Units are earned on the date of the Change of Control pursuant to Section 3(a) or 3(c) of this Agreement, payment will be made within 30 days following the date of the Change of Control. To the extent applicable, if the Change of Control triggering the right to payment under Section 3(a) or 3(c) above does not constitute a permitted distribution event under Section 409A(a)(2)(v) of the Code and the regulations thereunder, and where Section 409A of the Code applies to such distribution, then notwithstanding anything herein to the contrary, the cash payment will be made to you, to the extent necessary to comply with Section 409A of the Code, at the time specified in Section 8(a). In addition, for the avoidance of doubt, Section 18(c) of the Plan applies to any payment made pursuant to this Agreement.

9.Non-Assignability. The Performance Units are personal to you and are not transferable by you other than by will or the laws of descent and distribution. Any purported transfer or encumbrance in violation of the provisions of this Section 9 shall be void, and the other party to any such purported transaction shall not obtain any right to or interest in such Performance Units.

10.Responsibility for Taxes.

(a)Regardless of any action Avient or your employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on

2026 PU Award Agreement (Canada)

account or other tax related withholdings (“Tax Related Items”), you acknowledge that the ultimate liability for all Tax Related Items legally due by you is and remains your responsibility and that Avient and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax Related Items in connection with any aspect of the Performance Units grant, including the grant or vesting of the Performance Units, and (ii) do not commit to structure the terms of the grant or any aspect of the Performance Units to reduce or eliminate your liability for Tax Related Items.

(b)To the extent that Avient or the Employer is required to withhold taxes in accordance with applicable law in connection with the payment of the Performance Units in cash, Avient or the Employer shall withhold the amount necessary to satisfy any and all such withholding obligations.

11.Miscellaneous.

(a)Construction. The contents of this Agreement are subject in all respects to the terms and conditions of the Plan as approved by the Board and the shareholders of Avient, which are controlling. The interpretation and construction by the Board and/or the Committee of any provision of the Plan or this Agreement shall be final and conclusive upon you, your estate, executor, administrator, beneficiaries, personal representative and guardian and Avient and its successors and assigns.

(b)Leave of Absence. Any absence or leave approved by a duly constituted officer of Avient or any of its Subsidiaries will not be considered an interruption or termination of your service under this Agreement.

(c)Discretionary Grant; Future Value Unknown. The grant of the Performance Units is voluntary and discretionary and is being made on a one-time basis, and does not constitute a commitment to make any future awards. Furthermore, the grant will not be considered to be an employment contract and will not be considered salary or other compensation for purposes of any severance pay or similar allowance, except as otherwise required by law.

Information about you and your participation in the Plan, including, without limitation, your name, home address, email address and telephone number, date of birth, social insurance number, passport number or other identification number, salary, nationality, job title, any shares of stock or directorships held in Avient, and details of the Performance Units or other entitlement to shares of stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in your favor (“Data”) may be collected, recorded, held, used and disclosed by Avient, which is located in the United States, and any of its Subsidiaries and any non-Avient entities engaged by Avient to provide services in connection with this grant (a “Third Party Administrator”), for any purpose related to the administration of the Plan. By executing this Agreement, you explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of such Data for the exclusive purposes of implementing, administering and managing your participation in the Plan to Third Party Administrators, regardless of whether such Third Party Administrators are located within your country of residence.

(f)No Modifications to Existing Agreements. Except as specifically referenced herein, nothing in this Agreement impacts, changes, or otherwise modifies any existing agreements between you and Avient.

(g)Clawback. Notwithstanding anything in this Agreement to the contrary, you acknowledge and agree that (i) this Agreement, the Performance Units (and any settlement thereof) and any other performance-based incentive compensation or related amounts held or received by you are subject to any Avient clawback policy applicable to you, under their terms and conditions as may be in effect from time to time, including, without limitation, to implement Section 10D of the Exchange Act and any applicable rules or regulations (including applicable rules and regulations of any national securities exchange or national securities association on which the Common Shares may be traded) (the “Compensation Recovery Policy”), and (ii) that any relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of any such clawback policy from and after the effective date thereof. Further, by accepting the Performance Units covered by this Agreement, you (A) consent to be bound by the terms of the Compensation Recovery Policy, as applicable, (B) agree and acknowledge that you are obligated to and will cooperate with, and will provide any and all assistance necessary to, Avient in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Avient policy, and (C) agree that Avient may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy.

(h)Investigations. Notwithstanding anything to the contrary in this Agreement or in any other agreement, contract or arrangement with Avient or a Subsidiary, or in any policy, procedure or practice of Avient or a Subsidiary (collectively, the “Arrangements”), (i) nothing in the Arrangements or otherwise limits your right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or The Sarbanes-Oxley Act of 2002 or any comparable government agency pursuant to any comparable legislation in jurisdictions outside of the United States), and (ii) nothing in the Arrangements or otherwise prevents you from, without prior notice to Avient, providing information (including documents) to governmental authorities or agencies regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities or agencies regarding possible legal violations, and for purposes of clarity you are not prohibited from providing information (including documents) voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act or to any comparable government agencies pursuant to applicable legislation in jurisdictions outside of the United States. Avient nonetheless asserts and does not waive its attorney-client privilege over any information appropriately protected by privilege.

13.Compliance with Section 409A of the Code.

(a)To the extent applicable, it is intended that this Agreement, your Statement of Performance Goals, and the Plan comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to you. This Agreement and the Plan shall be administered in a manner consistent with this intent.

2026 Grant of Performance Units

Statement of Performance Goals

1.Definitions. For purposes of the grant of the Performance Units:

(a)“Adjusted Earnings per Share” shall mean: Net income, excluding special items and intangible asset amortization, divided by the weighted average of diluted shares. Special items are defined in the Company’s earnings releases, but include items such as gains or losses related to:

•Strategic or financial restructuring costs including: consolidation of operations; employee separation costs resulting from personnel reduction programs, plant closure and phase-out costs; executive separation agreements; asset impairments; debt extinguishment costs;

•Costs incurred directly in relation to acquisitions or divestitures;

•Environmental remediation costs, fines or penalties or liabilities for facilities no longer owned, discontinued or closed in prior years;

•Gains and losses on the divestiture of operating businesses, joint ventures and equity investments; gains and losses on facility or property sales or disposals;

•Certain tax adjustments;

•Results of litigation, fines or penalties, where such litigation (or action relating to the fines or penalties) arose prior to the commencement of the performance period;

The effect of changes in tax law, accounting principles or other such laws or provisions affecting reported results or the effect of adverse determinations by regulatory agencies relating to accounting principles or treatment;

•Mark-to-market adjustments associated with actuarial gains and losses on pension and other postretirement benefit plans; and

•Special Items related to changes in portfolio as set forth below:

•Divestitures:

oIn the event of the divestiture of a business unit during the performance period, the performance measures (threshold, target and maximum) will be adjusted to remove the net prospective loss of income and the related impact on earnings per share that such business unit was expected to have (as presented to the Board of Directors and applicable at the beginning of the performance period) during the portion of the performance period after the divestiture.

•Acquisitions:

oIn the event of an acquisition during the performance period, the performance measures (threshold, target and maximum) will be adjusted to include Pro Forma figures for the acquired assets for the remainder of the performance period.

oPro Forma, as referenced in the prior bullet, means the acquisition target’s prior year results corresponding to remaining time left in the performance period, adjusted for purchase accounting and acquisition financing, if any.

2026 PU Award Agreement (Canada)

(b)“Peer Group” shall mean the following entities, subject to the provisions in Section 2 below:

•Ashland Global Holdings Inc.

•Avery Dennison Corporation

•Cabot Corporation

•Celanese Corporation

•The Chemours Company

•Eastman Chemical Company

•FMC Corporation

•H.B. Fuller Company

•Hexcel Corporation

•Quaker Chemical Corporation

•RPM International Inc.

•The Scotts Miracle-Gro Company

•Sensient Technologies Corporation

•Stepan Company

•Trinseo S.A.

(c)“Relative Total Shareholder Return” or “rTSR” shall mean the percentile rank of Avient’s Total Shareholder Return with respect to the Performance Period as compared to (but not included in) the Total Shareholder Returns for all members of the Peer Group, ranked in descending order, at the end of the Performance Period.

(d)“Total Shareholder Return” shall mean, with respect to the Common Shares and the shares of common stock of each of the members of the Peer Group, a rate of return reflecting stock price appreciation, plus the reinvestment of dividends in additional shares of stock, from the beginning of the Performance Period through the end of the Performance Period. In general, Total Shareholder Return shall be determined for each of Avient and each Peer Group entity as a percentage (rounded to the nearest two decimal places) based on the quotient of (i) the sum of (A) the difference between the Ending Average (as defined below) and the Beginning Average (as defined below) plus (B) dividends, divided by (ii) the Beginning Average. For purposes of calculating Total Shareholder Return for Avient and the members of the Peer Group, the beginning stock price will be based on the average closing price for the 20 trading days preceding the first day of the Performance Period on the principal stock exchange on which the stock is then traded (the “Beginning Average”), and the ending stock price will be based on the average closing price for the 20 trading days preceding and including the last day of the Performance Period (the “Ending Average”).

2. Peer Group Adjustments. The following adjustments will be made to the Peer Group during the Performance Period:

(a)If any member of the Peer Group (i) files for bankruptcy, reorganization, or liquidation under any chapter of the U.S. Bankruptcy Code or similar non-U.S. law (collectively, “bankruptcy”), (ii) is the subject of an involuntary bankruptcy proceeding that is not dismissed within 30 days, (iii) is the subject of a stockholder-approved plan of liquidation or dissolution or makes a general assignment for the benefit of creditors, or (iv) ceases to conduct substantial business operations (provided that, for the avoidance of doubt, (A) the acquisition of a member of the Peer Group by another person or group of related persons by itself does not result in the company being treated as ceasing to conduct substantial business operations, (B) any acquisition by an unaffiliated person or group of related persons shall be subject to Section 2(b) below, and (C) treatment under this Section 2(a) shall not be affected by any subsequent reorganization, recapitalization

2026 PU Award Agreement (Canada)

or other restructuring pursuant to which the entity emerges from bankruptcy or otherwise continues or re-commences operations), then such entity will remain in the Peer Group, but Relative Total Shareholder Return for the Performance Period will be calculated as if such entity achieved Total Shareholder Return, placing it at the bottom (chronologically, if more than one such entity) of the Peer Group;

(b)If, by the end of the Performance Period, any member of the Peer Group has been acquired by an unaffiliated person or group of persons or is otherwise no longer existing as a publicly-traded company (other than for the reasons as described in Section 2(a) above), then such entity will be removed from the Peer Group; and

(c)Subject to Sections 2(a) and 2(b) above, if a member of the Peer Group undergoes an internal reorganization (e.g., inversion or establishment of a holding company structure) whereby the business and operations of the company (and its subsidiaries) constitute all the business and operations of the successor entity (and its subsidiaries) and the original member ceases to be publicly traded and such successor entity is publicly traded, such successor entity shall take the place of the original entity in the Peer Group.

APPENDIX A

NON-U.S. ADDENDUM

Additional Terms and Conditions for Grant of Performance Units

February 2026

Terms and Conditions

This Non-U.S. Addendum (this “Non-U.S. Addendum”) includes additional terms and conditions that govern the Performance Units granted to you under the Avient Corporation 2020 Equity and Incentive Compensation Plan, as amended and restated effective May 11, 2023 (the “Plan”), if you reside in Canada. Certain capitalized terms used but not defined in this Non-U.S. Addendum have the meanings set forth in the Plan and/or your award agreement that relates to your award (the “Agreement”). By accepting your award, you agree to be bound by the terms and conditions contained in the paragraphs below in addition to the terms of the Plan, the Agreement, and the terms of any other document that may apply to you and your award.

Notifications

This Non-U.S. Addendum also includes information regarding exchange controls and certain other issues of which you should be aware with respect to participation in the Plan. The information is based on the securities, exchange control, and other laws in effect in Canada as of February 2026. Such laws are often complex and change frequently. As a result, it is strongly recommended that you not rely on the information in this Non-U.S. Addendum as the only source of information relating to the consequences of your participation in the Plan because the information may be out of date at the time your Performance Units vest.

In addition, the information contained herein is general in nature and may not apply to your particular situation, and Avient Corporation (“Avient”) is not in a position to assure you of a particular result. Accordingly, you are advised to seek appropriate professional advice as to how the relevant laws in your country may apply to your situation.

Finally, if you are a citizen or resident of a country other than the one in which you are currently working, transferred employment after the Performance Units were granted to you, or are considered a resident of another country for local law purposes, the information contained herein may not apply.

COUNTRIES COVERED BY THIS NON-U.S. ADDENDUM:

Canada.

Non-U.S. Addendum (Canada) (Performance Unit)

NAI-5010402704v2

CANADA

Terms and Conditions

Other Termination. Sections 7(a) and 7(b) of the Agreement are hereby amended and replaced in their entirety to read as follows:

“(a)    If your employment with Avient or a Subsidiary terminates before the Payment Date for any reason other than as set forth in Section 3, 4, 5 or 6 above, the Performance Units will be forfeited, except to the extent otherwise expressly required to comply with minimum standards employment legislation, if applicable, in Canada. For the avoidance of doubt, such reasons shall include, without limitation, a termination of your employment with Avient or a Subsidiary for Cause (as defined in Section 3(d)(i) or Section 6(b), as applicable, depending on whether a termination of your employment occurs prior to or following a Change of Control), regardless of whether you are Retirement Eligible at such time.

(b)    For purposes of this Agreement, the date of occurrence of your termination of employment by Avient or a Subsidiary is the later of: (i) the date that you actually cease to perform services for Avient or a Subsidiary, as recorded by Avient or its Subsidiary, as applicable; and (i) the last day of the period during which you are entitled to notice of termination under applicable minimum employment standards legislation (the “Termination Date”).

For greater certainty, the Termination Date shall be determined without reference to any statutory severance or any contractual or common law notice of termination of which you are in receipt or may be eligible to receive at common law, pursuant to a contract, or otherwise; and no grants or damages in lieu thereof are payable with respect to any applicable statutory severance period or contractual or common law notice period. Notwithstanding the foregoing, in no event will you receive less under this Agreement than that required by applicable minimum employment standards legislation.

Avient and its Subsidiaries reserve the right to terminate the employment of any person, regardless of the effect of such termination of employment on entitlements under this Agreement. You hereby waive, and irrevocably release Avient and its Subsidiaries from, any claim or entitlement to compensation or damages that may arise from any forfeiture of the Performance Units as a result of the cessation of vesting on the Termination Date.”

Governing Law. Section 16 of the Agreement is hereby amended to add the following sentence to the end thereof to read as follows:

Non-U.S. Addendum (Canada) (Performance Unit)

NAI-5010402704v2

“Nothing in this Section 16 affects your right to pursue statutory relief available in your jurisdiction where such right cannot be waived under applicable law.”

Acknowledgement. By accepting the Performance Units subject to the Agreement through the Fidelity webportal (or its successor), you declare that you expressly agree with the provisions in the Plan and the Agreement, including those provisions regarding termination of employment described in the Plan, Sections 3, 6 and 7 of the Agreement, and the special terms and conditions set forth in this Non-U.S. Addendum.

Notifications

Tax Reporting. The Income Tax Act (Canada) (the “Tax Act”) and the regulations thereunder require an investor that is a “specified Canadian entity” to file an information return disclosing prescribed information where, at any time in a taxation year, the total cost amount of “specified foreign property” of the entity exceeds Cdn.$100,000. For these purposes, a “specified Canadian entity” includes a taxpayer resident in Canada that is not, among other things, a corporation or trust exempt from tax under Part I of the Tax Act. If the cash payment earned upon vesting of the Performance Units is held in a bank account outside of Canada, this reporting requirement may apply to you. The reporting rules in the Tax Act are complex and this summary does not purport to explain all circumstances in which reporting may be required by any investor. You should consult your own tax advisor regarding these reporting requirements.
