In this proxy statement, statements that are not reported financial results or other historical information are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They are based on management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. You can identify these statements by the fact that they do not relate strictly to historic or current facts. They use words such as "will," “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe” and other words and terms of similar meaning in connection with any discussion of future operating or financial condition, performance and/or sales. In particular, these include statements relating to future actions; prospective changes in raw material costs, product pricing or product demand; future performance; estimated capital expenditures; results of current and anticipated market conditions and market strategies; sales efforts; expenses; the outcome of contingencies such as legal proceedings and environmental liabilities; and financial results. Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to:
•disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future;
•the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks;
•disruptions or inefficiencies in our supply chain, logistics, or operations;
•changes in laws and regulations in jurisdictions where we conduct business, including with respect to plastics and climate change;
•fluctuations in raw material prices, quality and supply, and in energy prices and supply;
•demand for our products and services;
•production outages or material costs associated with scheduled or unscheduled maintenance programs;
•unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters;
•our ability to pay regular quarterly cash dividends and the amounts and timing of any future dividends;
•information systems failures and cyberattacks;
•our ability to service our indebtedness and restrictions on our current and future operations due to our indebtedness;
•amounts for cash and non-cash charges related to restructuring plans that may differ from original estimates, including because of timing changes associated with the underlying actions;
•other factors affecting our business beyond our control, including without limitation, changes in the general economy, changes in interest rates, changes in the rate of inflation, geopolitical conflicts, and any recessionary conditions; and
•other factors described in our Annual Report on Form 10-K for the year ended December 31, 2024 under Item 1A, “Risk Factors.”
We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. Investors should bear this in mind as they consider forward-looking statements. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by law. You are advised, however, to consult any further disclosures we make on related subjects in our reports on Forms 10-Q, 8-K and 10-K filed with the Securities and Exchange Commission. You should understand that it is not possible to predict or identify all risk factors. Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

OUR PURPOSE AND STRATEGIC FRAMEWORK
Our Purpose and Strategic Framework
2024 was an important year of change for Avient. We developed and launched a new strategy to deliver and accelerate organic growth. Our purpose at Avient is to be an innovator of materials solutions that help our customers succeed, while enabling a sustainable world. Our local touch and customer engagement, combined with our global reach, allows us to serve customers with agility. We harness the collective strength of 9,000+ employees worldwide to collaborate and build on each other’s ideas. In doing so, we innovate materials solutions that help our customers overcome their challenges or capitalize on opportunities provided by the fast-changing world and secular trends. Our expanding portfolio of offerings includes colorants, advanced composites, functional additives, engineered materials, and Dyneema®, the world’s strongest fiber™.
We have a two-pronged strategic approach, where we seek to intersect high-growth markets and secular trends with our technologies to (1) build new platforms of scale by playing bigger and bolder in high-growth markets, and (2) catalyze the core of our business, maximizing the impact of what we have. Our strategy utilizes four supporting strategic drivers: Portfolio Prioritization; Amplify Innovation; Digital for Operational Excellence and Growth; and Leadership, Talent and Culture for the Avient of the Future. All of this is underpinned by the established foundational strengths of Avient, which have been built and refined over the 25-year history of the Company. While our strategy has evolved, we remain committed to being a world-class organization by continuing to focus on People, Products, Planet, and Performance.
People
Avient has elevated our People strategy in alignment with our new Company strategy, which is captured in the strategic driver "Leadership, Talent and Culture for the Avient of the Future." The success and growth of our business depend in large part on our ability to attract, develop and retain a broad-base of 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. As of December 31, 2024, Avient employed approximately 9,200 people, 34% of which were located in the U.S. and Canada, 33% were located in EMEA, 26% were located in Asia, and 7% 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 2024, we had our safest year ever with a record low recordable incident rate. Continuous improvement and preventative risk reductions are key focus areas, and in 2024, one of our annual incentive plan metrics measured the 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.
Belonging and Impact
We recognize the benefits that a sense of belonging brings to our organization, including delivering better business outcomes. Our talented people leverage their unique backgrounds across a myriad of aspects and
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 4

OUR PURPOSE AND STRATEGIC FRAMEWORK
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 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.
We leverage Employee Resource Groups to help educate and inspire our global workforce and fortify strong business practices. Employee Resource Groups are open to all Avient employees and are designed to create a workplace that promotes a sense of belonging and strengthens our culture.
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.
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, employees in over 40 countries, and more than 130 locations participated, providing actionable feedback to support our ongoing employee engagement efforts. We are proud that our employees feel we are a Great Place to Work®, and in 2024, we received our sixth certification. Understanding how our employees feel about their experiences at Avient and our culture is critical and helps us ensure that the right competencies and behaviors are developed across the organization.
Products
Innovation is the lifeblood of a materials solutions company, and our transformation has been defined by the ongoing evolution of our portfolio offerings to meet the product performance and sustainability needs of our customers. We believe our innovation pipeline remains robust, as we leverage our formulation and materials science expertise. Our innovations cover a broad range of products in several end markets, from insulator rods in power distribution to life saving vests and protective materials for the military and law enforcement agencies manufactured using Dyneema® fiber.
We offer a broad portfolio of technologies that help our customers succeed, while enabling a sustainable world. Our efforts focus on serving secular trends and supporting our customers' goals to lightweight, use less materials, use bio-based materials, or increase the recyclability or recycled content of their end products. Our materials science expertise can make possible equal or better product performance while using less material, reducing energy consumption, minimizing waste or by incorporating into products used for clean energy infrastructure, like wind and solar, just to name a few. As the world continues to shift from operating in a linear economy to a circular economy and to a lower carbon footprint, Avient is proud to be a part of the solution.
Planet
The need to take care of our precious planet continues to be important. Avient is fully committed to protecting the environment by conserving natural resources and preventing pollution. Through our environmental impact

assessments within our Environmental, Health & Safety ("EH&S") Management System, we have focused on the following key topics: energy and emissions, as well as effluents and waste from our operations. Avient’s Corporate EH&S Department is responsible for overseeing these areas, and it receives input and oversight from our leadership team and Board of Directors.
Performance

ADVISORY VOTE
PROPOSAL 2—Approval, on an Advisory Basis, of Named Executive Officer Compensation
As required under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") and Section 14A of the Securities Exchange Act of 1934 (the “Exchange Act”), our Board is submitting a “Say on Pay” proposal for shareholder consideration. While the vote to approve the compensation of the executive officers named in the 2024 Summary Compensation Table of this proxy statement (the "Named Executive Officers" or "NEOs") is non-binding and solely advisory in nature, our Board and the Compensation Committee will review the voting results. If there are a significant number of negative votes, we will seek to understand the concerns that influenced the vote and expect to address them in making future decisions about our executive compensation programs.
At our 2023 Annual Meeting, shareholders voted to hold an advisory “Say on Pay” vote on an annual basis. Accordingly, we have determined to submit an advisory vote to approve our Named Executive Officer compensation to our shareholders at each annual meeting (with the next vote expected to occur in 2026) until the Company seeks another advisory vote on the frequency of the advisory vote on our Named Executive Officer compensation program (which next frequency vote is anticipated to occur at the 2029 Annual Meeting).
As described more fully in the “Compensation Discussion and Analysis” section of this proxy statement, the Compensation Committee of our Board has structured our executive compensation program to achieve the following key objectives:

Objective | How Our Executive Compensation Program Achieves this Objective
Pay-For-Performance | Setting a significant portion of each Named Executive Officer’s total compensation in the form of variable compensation that is earned when pre-established financial performance goals are achieved
Align Executive Compensation with Shareholders’ Interests | Focusing incentive programs on the critical performance measures that determine Avient’s overall success and reward executives for the attainment of short-term results, balanced with the need for sustainable long-term success
Attract, Motivate and Retain Management | Competing effectively to attract, motivate and retain a management team that leads in setting and achieving the overall goals and objectives of Avient

PROXY STATEMENT 2025 | Annual Meeting of Shareholders 23

ADVISORY VOTE
We urge shareholders to read the “Compensation Discussion and Analysis” section of this proxy statement, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives. We also encourage you to review the 2024 Summary Compensation Table and other related compensation tables and narratives in the “Executive Compensation” section of this proxy statement, which provide detailed information regarding the compensation of our Named Executive Officers. The Board and the Compensation Committee believe that the policies and procedures described and explained in the “Compensation Discussion and Analysis” section of this proxy statement are effective in achieving our business goals and the compensation of our Named Executive Officers reported in the “Executive Compensation” section of this proxy statement has supported and contributed to the Company’s recent and long-term success.

Our Board recommends a vote FOR the approval, on an advisory basis, of Named Executive Officer compensation.

We believe you should vote “FOR” our Named Executive Officer compensation program and approve the following resolution because the compensation actually earned by our Named Executive Officers for our 2024 performance was aligned with our pay-for-performance objectives, our Company’s performance and shareholder interests:
“RESOLVED, that the compensation paid to Avient’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and related narrative discussion, is hereby APPROVED.”
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 24

AUDIT
PROPOSAL 3—Ratification of the Appointment of Ernst & Young LLP ("EY") as Our Independent Registered Public Accountant
The Audit Committee has appointed EY as our independent registered public accounting firm to audit our consolidated financial statements for the fiscal year ending December 31, 2025. The Board recommends ratification of the Audit Committee’s appointment of EY.
The selection of EY as our independent registered public accounting firm is not required to be submitted to a vote of our shareholders for ratification. The Sarbanes-Oxley Act of 2002 requires that the Audit Committee be directly responsible for the appointment, compensation and oversight of our independent auditor. The Board is submitting the appointment to our shareholders for ratification as a matter of good corporate practice. If our shareholders fail to vote on an advisory basis in favor of the selection, the Audit Committee will reconsider whether to retain EY and may retain that firm or another firm without re-submitting the matter to our shareholders. Even if our shareholders ratify the appointment, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in our best interests and the best interests of our shareholders.
A representative of EY is expected to be present at the Annual Meeting. The representative will be given an opportunity to make a statement if desired and to respond to appropriate questions regarding EY’s examination of our consolidated financial statements and records for the year ended December 31, 2024.

Our Board recommends a vote FOR the ratification of the appointment of EY as our independent registered public accounting firm for the fiscal year ending December 31, 2025.

Independent Registered Public Accountant Services and Related Fee Arrangements
Services provided by EY, our independent registered public accounting firm, and related fees in each of the last two fiscal years were as follows:
Audit Fees.

AUDIT
Our Audit Committee Pre-Approval Policy for all Audit and Non-Audit Services and Related Fee Arrangements (the “Pre-Approval Policy”) requires our Audit Committee to pre-approve all audit and non-audit services performed by EY in order to assure that the provision of such services and related fee arrangements do not impair EY’s independence. Under the Pre-Approval Policy, the Audit Committee may delegate pre-approval authority to one or more of its members, and the member or members to whom the Audit Committee delegates such authority must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee has formally delegated this pre-approval authority to its Chair. Management has no authority to approve services performed by EY that have not been pre-approved by the Audit Committee. The term of any pre-approval is 12 months from the date of pre-approval, unless the Audit Committee specifically provides for a different period.
EY will provide us a description of work scope and supporting back-up documentation regarding the specific services they will provide. At each meeting of the Audit Committee, the current year’s previously pre-approved independent auditor fees along with any proposed revisions will be presented for approval. Any interim requests between Audit Committee meetings to provide services that require separate pre-approval will be submitted to the Audit Committee or the Audit Committee Chair by EY and our Chief Financial Officer, or Controller, and must include a statement as to whether, in each of their respective views, the request is consistent with the Securities and Exchange Commission’s ("SEC") rules on auditor independence.
Report of the Audit Committee
The Audit Committee assists the Board in fulfilling its oversight responsibilities to shareholders relating to the integrity of the Company’s consolidated financial statements, the Company’s compliance with legal and regulatory requirements, the independent registered public accounting firm’s qualifications and independence, and the performance of the Company’s internal and independent auditors. The Audit Committee’s specific responsibilities are described in its charter, which is available on the Company’s website at: www.avient.com under the heading “Investors” and the subheading “Governance.”
The Audit Committee currently consists of six Directors, each of whom our Board has determined to meet the requirements of the New York Stock Exchange (the “NYSE”) for independence and financial literacy. Five members of the Audit Committee also meet the requirements of an “audit committee financial expert” as defined by the SEC.
The Audit Committee approves, subject to shareholder ratification, the appointment of the Company’s independent registered public accounting firm and pre-approves all audit and non-audit services to be performed by the firm. The Audit Committee has retained Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025. The Audit Committee through its Chair is also directly involved in the selection of EY’s lead engagement partner, which occurs every five years. The most recent lead engagement partner rotation occurred at the start of 2022.
Avient’s Audit Committee believes that the continued retention of EY to serve as Avient’s independent registered public accounting firm is in the best interests of Avient and its shareholders. In making such determination, the Audit Committee considers, among other things, an evaluation of EY’s performance, qualifications, independence, tenure, and appropriateness of fees, as well as the potential impact of changing auditors. EY has been retained as the independent registered public accounting firm for Avient and its predecessor companies, PolyOne Corporation and The Geon Company, continuously since 1993.
Management has the primary responsibility for the completeness and accuracy of the Company’s consolidated financial statements and disclosures, the financial reporting process and the effectiveness of the Company’s internal control over financial reporting. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements included in the Company’s Annual Report on Form
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 26

AUDIT
10-K for the year ended December 31, 2024 with management and the independent registered public accounting firm, including any significant changes in the Company’s selection or application of accounting principles.
The Audit Committee also reviewed and discussed with management and the independent registered public accounting firm management’s report on internal control over financial reporting, including the significance and status of control deficiencies identified and the results of remediation efforts undertaken, to determine the effectiveness of internal control over financial reporting at December 31, 2024. The Audit Committee reviewed with the independent registered public accounting firm, which has the responsibility for expressing an opinion on the conformity of the consolidated financial statements with generally accepted accounting principles and applicable rules and regulations, their judgments as to the quality, not just the acceptability, of Avient’s critical accounting principles and estimates and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. The Audit Committee also reviewed with the independent registered public accounting firm its report on the Company’s internal control over financial reporting at December 31, 2024, including the basis for its conclusions.
The Audit Committee reviewed and discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. In addition, EY has provided the Audit Committee with the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with EY their firm’s independence from management and Avient. The Audit Committee has approved all audit, audit-related and non-audit services and fees provided to the Company by the independent registered public accounting firm in accordance with its approval process. Based upon the Audit Committee’s considerations, the Audit Committee has concluded that EY is independent.
The Audit Committee discussed with Avient’s internal and independent auditors the overall scope and audit plans and evaluated their performance. The Audit Committee meets with the internal and independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of Avient’s internal control over financial reporting, and the overall quality of Avient’s financial reporting.
In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board (and the Board has approved) that the audited consolidated financial statements and management’s assessment of the effectiveness of the Company’s internal control over financial reporting be included in the Annual Report on Form 10-K for the year ended December 31, 2024, to be filed with the SEC.
All members of the Audit Committee concur with this report.

PROXY STATEMENT 2025 | Annual Meeting of Shareholders 27

CORPORATE GOVERNANCE
Corporate Governance
Director Independence
Our Corporate Governance Guidelines provide that a substantial majority of the members of our Board should be “independent.” To be considered independent, the Board, with input and a recommendation from the Governance and Corporate Responsibility Committee, must affirmatively determine that a given Director has no material relationship with the Company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company) and is free from any business, family or other relationship that would reasonably be expected to interfere with the exercise of independent judgment as a Director. The Board considers even immaterial relationships, including transactions, relationships and arrangements with the Company, in its decision-making process to ensure a complete view of each Director’s independence. Under categorical independence standards adopted by our Board, the Board must determine that a Director is not independent if he or she fails to meet the independence standards under the listing standards of the NYSE.
In addition, our categorical independence standards provide that the following categories of relationships between an outside Director and the Company will be treated as immaterial for purposes of determining a Director’s independence.
•If the Director is, or has an immediate family member who is, a partner (general or limited) in, or a controlling stockholder, equity holder, executive officer, other employee or director of any organization to which the Company made, or from which the Company received, payments for property or services in the current or any of the past three fiscal years where the amount involved in such transaction in any such fiscal year was less than the greater of $1 million or 2% of the organization’s consolidated gross revenues for that year;
•If the Director is, or has an immediate family member who is, a director or trustee of any organization to which the Company has made, or from which the Company has received payments for property or services, and the Director (or his or her immediate family member) was not involved in the negotiations of the terms of the transaction, did not, to the extent applicable, provide any services directly to the Company, and did not receive any special benefits as a result of the transaction; or
•If the Director, or an immediate family member of the Director, serves as an officer, director or trustee of a foundation, university, charitable or other not-for-profit organization, and the Company’s discretionary charitable contributions to the organization, in the aggregate are less than the greater of $1 million or 2% of that organization’s latest publicly available annual consolidated gross revenues.
Our categorical independence standards and the material relationship considerations set forth above are found within our Corporate Governance Guidelines, which are available on our website at www.avient.com, under the heading “Investors” and the subheading “Governance.”
Our Board performed its independence review earlier this year. In applying the categorical standards set forth above and assessing the materiality of any relationships, the Board affirmatively determined that each of our current Directors (Messrs. Abernathy, Fearon, Goff, Green, Jellison, Nicolas, Preete, and Wulfsohn, and Mses. Lin, Mink, and Verduin), with the exception of Dr. Khandpur, is independent and meets the categorical independence standards described above, has no material relationship with the Company other than that arising solely from the capacity as a Director and, in addition, satisfies the independence requirements of the NYSE, including the NYSE independence standards applicable to the committees on which each such Director serves.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 28

CORPORATE GOVERNANCE
Board Leadership Structure
Pursuant to our Corporate Governance Guidelines, the Board selects the Chairman of the Board and Chief Executive Officer and determines from time to time whether the positions are to be combined and filled by one person or separated and filled by two persons. Pursuant to our Corporate Governance Guidelines, the Board’s policy as to whether these roles should be separate is to adopt the practice that best serves the Company’s needs at any particular time. The Company's current Board leadership structure provides for a Non-Executive Chairman of the Board who is appointed by the Board. Mr. Fearon has served as the Non-Executive Chairman of our Board since December 2023. The Board believes that this structure allows our Chief Executive Officer to focus on operating and actively managing the Company and the Non-Executive Chairman to provide guidance, an additional layer of independent oversight of Avient, and an avenue of communication between management and the independent Directors. With independent members of the Board serving as chairpersons and members of our Audit Committee, Compensation Committee, and Governance and Corporate Responsibility Committee, this leadership structure further enables the Board to provide independent oversight of material risks affecting the Company that are within the purview of such committees as further described under “Board Oversight of Risk.”
Majority Voting for Directors
Our Corporate Governance Guidelines contain a policy relating to majority voting. Pursuant to the policy, any nominee for election as a Director of the Board who receives a greater number of votes “withheld” from his or her election than votes “for” his or her election in an election of Directors that is not a contested election is expected to tender his or her resignation as a Director to the Board promptly following the certification of the election results. Neither abstentions nor broker non-votes will be deemed to be votes for or withheld from a Director’s election for purposes of the policy. The Governance and Corporate Responsibility Committee (without the participation of the affected Director) will consider each resignation tendered under the policy and recommend to the Board whether to accept or reject it. The Board will then take appropriate action on each tendered resignation, taking into account the Governance and Corporate Responsibility Committee’s recommendation. The Governance and Corporate Responsibility Committee, in making its recommendation, and the Board, in making its decision, may consider any factors or other information that it considers appropriate, including, without limitation, the reasons (if any) given by shareholders as to why they withheld their votes, the qualifications of the tendering Director and his or her contributions to the Board and to Avient, and the results of the most recent evaluation of the tendering Director’s performance by the other members of the Board. The Board will promptly disclose its decision whether to accept or reject the Director’s tendered resignation and, if applicable, the reasons for rejecting the tendered resignation.
Board Oversight of Risk
Our Board oversees a Company-wide approach to risk management that is designed to support the achievement of our strategic objectives and improve long-term organizational performance, which we believe will enhance shareholder value. The Board believes that risk management is not only understanding the risks we face and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for Avient overall.
Our Board administers its risk oversight function directly and through its committees. The Board has delegated specific risk oversight responsibility to the committees of the Board. Under its Charter, the Audit Committee has oversight of the Company’s risk management processes, including risk oversight related to cybersecurity and data protection. The Audit Committee is responsible for discussing with management our major financial risk exposures and the steps management has taken to monitor and control such exposures, including our risk

CORPORATE GOVERNANCE
assessment and risk management policies. The Audit Committee also reviews reports related to on-going assessments of the Company’s risk management processes and system of internal control. Specifically regarding cybersecurity, the Audit Committee regularly receives updates from management regarding the Company's cybersecurity threats and defense and detection capabilities, incident response plans and employee training activities. Members of our Information Technology team provide this detailed overview to the Audit Committee of the Company’s cybersecurity efforts and management of that risk at least twice per year. In some instances the full Board also receives the update.
The Environmental, Health and Safety Committee periodically reviews with management any significant operational risks or exposures faced by Avient relating to safety, health, physical security, environmental, and product stewardship, and steps taken by management to minimize such risks and exposures to the Company and its constituencies. The Environmental, Health and Safety Committee also provides oversight of the systems that are in place to monitor and mitigate our carbon footprint and the physical risks associated with climate change.
The Compensation Committee annually reviews and assesses risks arising from the Company's compensation policies and practices, as described below in the “Risk Assessment of the Compensation Programs” section of this proxy statement.
The Governance and Corporate Responsibility Committee oversees risks related to the Company's programs, policies, and practices from a strategic perspective related to certain environmental, social, and governance matters, including with regard to how the Board and management evaluate and integrate such matters into our business strategy and decision-making.
Our Board oversees and monitors these committees in exercising their responsibilities relating to risk.
Our Board sets the appropriate “tone at the top” when it comes to risk tolerance and management. Our Board confirms that the risk management processes designed and implemented by our management team are adapted to the Board’s corporate strategy and are functioning as directed. The Board also participates in an ongoing effort to assess and analyze the most likely areas of future risk for the Company by asking our management team to discuss the most likely sources of material future risks and how we are addressing any significant potential vulnerability.
The Board as a group is regularly updated on specific risks in the course of its review of corporate strategy, business plans and reports to the Board by management and its respective committees. The Board believes that certain important categories of risk are assigned to committees that consist of independent Directors. These committees receive, review and evaluate management reports on risk, thereby preserving the benefit of independent risk oversight. The Board believes that the leadership structure of our Board is appropriate given the Board’s oversight of risk as described above.
Board Oversight of ESG and Sustainability Matters
Our Governance and Corporate Responsibility Committee assists the Board in fulfilling its oversight responsibilities related to corporate responsibility, environmental, social and governance matters. Further, our Environmental, Health and Safety Committee oversees and monitors the establishment and maintenance by management of comprehensive safety, health, environmental, physical security and product stewardship policies, standards and practices for the Company. Our Environmental, Health and Safety Committee also provides oversight of the systems that are in place to monitor and mitigate our carbon footprint and physical risks associated with climate change. Additionally, Avient formed an internal Sustainability Council in 2019 that is responsible for managing sustainability initiatives at all levels of our organization in support of our long-term business strategy.

CORPORATE GOVERNANCE
Code of Ethics, Code of Conduct and Corporate Governance Guidelines
In accordance with applicable NYSE listing standards and SEC regulations, the Board has adopted a Code of Ethics, Code of Conduct and Corporate Governance Guidelines. These are also posted and available on our website at www.avient.com, under the heading “Investors” and the subheading “Governance.”
Related Person Transactions
Under our Code of Conduct, we prohibit all employees, including our officers and non-employee Directors from engaging in activities that would impact their ability to carry out their duties in an independent, objective fashion. The Board recognizes that some transactions, arrangements, and relationships present a heightened potential for conflicts of interest (or the perception of conflicts of interest) and, therefore, has adopted a written Related Person Transactions Policy (the “Policy”) governing these transactions. The Policy generally applies to “Related Person Transactions,” defined as any transaction, arrangement or relationship, or series of similar transactions, arrangements or relationships (including any indebtedness or guarantee of indebtedness), in which (i) the Company or any of its subsidiaries was, is or will be a participant and the amount involved exceeds $120,000 and (ii) any of the following persons had, has or will have a direct or indirect material interest (except those transactions, arrangements or relationships that would not be required to be disclosed pursuant to SEC rules after considering the materiality thresholds set forth in Item 404 of Regulation S-K under the Exchange Act):
•our Directors, Director nominees, or Executive Officers;
•any immediate family member of any of the foregoing persons;
•any person who is known to be the beneficial owner of more than 5% of any class of our voting securities; or
•any entity in which any of the foregoing persons is employed or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest.
Pursuant to the Policy, all Related Person Transactions are subject to reasonable prior review and approval by the Audit Committee. In determining whether to approve a Related Person Transaction, the Audit Committee considers the following factors, among others: (1) whether the transaction is in conformity with the Company’s Code of Conduct and is in the best interests of the Company; (2) whether the transaction would be in the ordinary course of the Company’s business; (3) whether the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party; (4) the disclosure standards set forth in Item 404 of Regulation S-K; and (5) whether the transaction could call into question the status of any Director or Director nominee as an independent director under the rules of the NYSE.
In circumstances where it is not reasonable or practical to wait until the next Audit Committee meeting to review a proposed Related Person Transaction, the Chair of the Audit Committee may review and approve such Related Person Transaction in accordance with the Policy, subject to ratification by the Audit Committee at its next regularly scheduled meeting. Further, if management becomes aware of any Related Person Transactions that were not previously approved under the Policy, such Related Person Transactions shall be presented to the Audit Committee as promptly as practicable for its action.
If a Related Person Transaction is ongoing, the Audit Committee will be responsible for overseeing and annually assessing the continued appropriateness of such Related Person Transaction and may establish guidelines for the Company’s management team to follow in its ongoing dealings with the related person.
There were no related person transactions in 2024.

Communication with the Board
Shareholders and other interested parties who wish to communicate directly with the Board as a group, the non-management or independent Directors as a group, or with any individual Director may do so by writing to the Secretary, Avient Corporation, 33587 Walker Road, Avon Lake, Ohio 44012.

Directors may at any time review a log of all correspondence we receive that is addressed to members of the Board and request copies of any such correspondence. Concerns relating to accounting, internal controls or auditing matters are immediately brought to the attention of our internal audit department and handled in accordance with procedures established by the Audit Committee for such matters.
Board and Committees
Board Attendance
The Board met six times during 2024, the calendar year being our fiscal year. In 2024, each member of our Board attended at least 75% of the aggregate number of meetings of the Board and the committees on which he or she served (held during the period in which the director served). Each director is expected to attend the Company's annual meetings of shareholders. In 2024, all of our Directors attended the annual meeting of shareholders.
Board Committees
As of the date of this proxy statement, our Board has twelve Directors and the following four committees: Audit, Compensation, Governance and Corporate Responsibility, and Environmental, Health and Safety. Each committee meets periodically throughout the year, reports its actions and recommendations to the Board, receives reports from senior management, annually evaluates its performance and has the authority to retain outside advisors in its discretion. The primary responsibilities of each committee are summarized below and set forth in detail in each committee’s written charter, which is located on our website at www.avient.com under the heading “Investors” and the subheading “Governance.”

Compensation Committee, and interacts with management to gather the data needed to prepare reports for Compensation Committee review.
The Compensation Committee periodically reviews the relationship with the Consultant including the level and quality of services provided, as well as fees for those services. In addition, expenses for other consulting services provided to Avient by the Consultant that are not related to executive compensation are monitored to ensure that executive compensation consultant independence is maintained. During 2024, the Consultant did not provide any services to the Company that were not related to executive and Director compensation.
The Compensation Committee considered all relevant factors, specifically including six consultant independence factors under Rule 10C-1(b)(4)(i) through (vi) under the Exchange Act, in assessing the independence of the Consultant. The Compensation Committee reviewed each factor as well as information provided by the Consultant that related to and was responsive to each factor, which assisted in the assessment. Upon completing this assessment, the Compensation Committee also determined that no “conflicts of interest have been raised by the work performed by the Consultant.”

CORPORATE GOVERNANCE
section of this proxy statement. The Governance and Corporate Responsibility Committee uses a variety of methods for identifying nominees for election as Directors to our Board, including third-party search firms, recommendations from current Board members and recommendations from shareholders. When using a third-party search firm, the Governance and Corporate Responsibility Committee generally provides such firm with guidance as to the skills, experience, and qualifications that the Governance and Corporate Responsibility Committee is seeking in potential candidates, and the search firm identifies candidates for the Governance and Corporate Responsibility Committee’s consideration. Although the Governance and Corporate Responsibility Committee does not have specific minimum qualifications that must be met for a candidate to be nominated as a Director, the Governance and Corporate Responsibility Committee considers the following criteria in evaluating potential candidates:
•Business or professional experience;
•Knowledge and skill in certain specialty areas such as accounting and finance, international markets, physical sciences and technology or the specialty materials industry;
•Personal characteristics, such as ethical standards, integrity, judgment, leadership and the ability to devote sufficient time to our affairs;
•Substantial accomplishment with demonstrated leadership capabilities;
•Freedom from outside interests that conflict with our best interests;
•The unique backgrounds and experience each member will bring to the Board, including differences in viewpoint, background and skill; and
•Our needs from time to time.
The Governance and Corporate Responsibility Committee believes that having a Board with a broad range of skills, characteristics, and expertise helps foster greater innovation, unique thinking and stronger governance. The process to determine director nominees for election to the Board is based upon the recommendations of the Governance and Corporate Responsibility Committee, which is responsible for selecting directors to recommend to the Board for election by the shareholders and to recommend qualified individuals to fill vacancies between shareholder meetings. The Governance and Corporate Responsibility Committee will make a preliminary review of a prospective candidate’s background, career experience, and qualifications based on available information. If a consensus is reached by the Governance and Corporate Responsibility Committee that a particular candidate would likely contribute positively to the Board’s mix of skills and experiences, the Governance and Corporate Responsibility Committee will conduct interviews with the candidate and may invite other Board members or senior Avient executives to interview the candidate to assess the candidate’s overall qualifications. In considering director nominees, the Governance and Corporate Responsibility Committee considers the Board skills matrix to determine any gaps in skills and characteristics identified in the current composition of our Board, and the desirable skills/characteristics for a new Board member.
The Governance and Corporate Responsibility Committee also considers such other relevant factors as it deems appropriate, including the current composition of the Board, the balance of management and independent Directors, and the need for subject matter expertise. A nominee for election to the Board who is suggested by a shareholder will be evaluated by the Governance and Corporate Responsibility Committee in the same manner as any other nominee for election to the Board. Finally, if the Governance and Corporate Responsibility Committee determines that a candidate should be nominated for election to the Board, the Governance and Corporate Responsibility Committee will present its findings and recommendation to the full Board for approval.

Board Refreshment
The Governance and Corporate Responsibility Committee is charged with reviewing the composition of the Board and refreshing the Board as appropriate. In the past five years, the Governance and Corporate Responsibility Committee has identified and recommended two new independent Directors. The average tenure of all Directors is nine years. The chart below shows the tenure of our Directors following the Annual Meeting (assuming all nominees are elected) in each of the following categories: five or fewer years of service; six to ten years of service; and more than ten years of service.
Board Tenure
Our Corporate Governance Guidelines provide that non-employee Directors may not stand for re-election following the date of the Director’s 72 nd birthday, although the Board may waive this limitation if it determines such waiver to be in the best interests of the Company.
Our Governance and Corporate Responsibility Committee periodically evaluates the composition of the full Board, and seeks to compose a Board with members who have a broad range of experiences, skills and backgrounds.

NON-EMPLOYEE DIRECTOR COMPENSATION
2024 Non-Employee Director Compensation
We compensate non-employee Directors for their service on the Board with a combination of cash and equity awards, the amounts of which are commensurate with their role and involvement, and consistent with peer company practices. In setting Director compensation, we consider the significant amount of time our Directors spend fulfilling their duties as well as the skill level required of members of our Board. We compensate our non-employee Directors in a way that is competitive, attracts and retains a high caliber of Directors, and aligns their interests with those of our shareholders.
Non-Employee Director Compensation Highlights
•Annual review and assessment of non-employee Director compensation by the Compensation Committee;
•Comparative assessment of non-employee Director compensation by the Consultant against market data;
•Emphasis on equity in the overall compensation mix to support shareholder alignment;
•Shareholder-approved limit on cash and equity compensation to non-employee Directors under our Amended and Restated 2020 Equity and Incentive Compensation Plan (the "2020 Plan"); and
•Robust stock ownership guideline set at 12,500 shares for each non-employee Director (which amount is equivalent to more than four times the annual cash retainer, based on the Company's closing stock price on December 31, 2024 of $40.86).
Non-Employee Director Retainer and Meeting Fees
In 2024, we paid our non-employee Directors a retainer at an annual rate of $257,500 (payable in quarterly installments in arrears) consisting of $110,000 in cash and $147,500 in targeted value of fully vested common shares (subject to rounding). In 2024, the Compensation Committee analyzed competitive market data provided by the Consultant relating to both the cash retainer (including the additional cash retainers for the Non-Executive Chairman and committee chairs, and unscheduled meeting fees) and the equity award value. These compensation elements were compared against Avient’s peer group (as described in the "Compensation Discussion and Analysis"), as well as a general industry group consisting of 102 comparably-sized general industry (excluding financial services and utilities) companies based on median revenues. Following this review, effective for compensation paid starting in the third quarter of 2024, the Compensation Committee implemented the following changes: (1) increase in annual equity award value to each non-employee Director from $140,000 to $155,000; and (2) increase in Audit Committee Chair retainer from $20,000 to $25,000, increase in Compensation Committee Chair retainer from $15,000 to $20,000, increase in Governance and Corporate Responsibility Committee Chair retainer from $15,000 to $20,000, and increase in Environmental, Health and Safety Committee Chair retainer from $15,000 to $20,000. The Compensation Committee determined that such changes were appropriate to account for increases in the market range for total compensation paid to directors and to keep the equity retainer aligned with the market range. Other than as set forth above, no other changes were made to non-employee Director compensation.
No fees are paid for attendance at regularly scheduled board meetings. We pay individual meeting fees only as follows: $2,000 in cash for each unscheduled Board and committee meeting attended; and $1,000 in cash for participation in each unscheduled significant telephonic Board and committee meeting. In addition, the Non-Executive Chairman receives an additional fixed annual cash retainer (payable in quarterly installments in arrears) equal to $130,000. We also reimburse Directors for expenses associated with each meeting attended.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 38

NON-EMPLOYEE DIRECTOR COMPENSATION
Non-employee Directors may defer payment of all or a portion of their annual cash retainer under our Deferred Compensation Plan for Non-Employee Directors (“Deferred Compensation Plan”). Directors may also elect to have their cash retainer converted into our common shares. These shares, as well as the annual retainer consisting of fully vested common shares, may also be deferred under the Deferred Compensation Plan. In 2024, we awarded shares to Directors under the 2020 Plan. Deferred compensation for the participating Directors, whether in the form of cash or common shares, is recorded in a recordkeeping account that reflects the amounts deferred and any applicable notional earnings. Dividends, if any, on the deferred common shares are accrued for the benefit of the participating Directors.

Fees Earned or Paid in Cash (column (a))
Non-employee Directors may defer payment of all or a portion of their annual cash retainer (payable in quarterly installments in arrears), as well as meeting, Lead Director, Non-Executive Chairman, and committee chair fees, into the Deferred Compensation Plan. Fees are prorated based upon time served as a Director, Non-Executive Chairman, or committee chair in any applicable quarter.
Stock Awards (column (b))
Our non-employee Directors’ stock compensation consisted of an annual award (payable in quarterly installments in arrears) of fully vested common shares (deferrable by election). We determined the number of shares to be granted each quarter by dividing the applicable dollar value by the arithmetic average of the high and low stock price on the last trading day of the applicable quarter and rounding to a whole share as partial shares are not issued. We used the following quarterly per share fair market values, calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”), in calculating the number of shares: March 28, 2024 — $43.40 (808 shares); June 28, 2024 — $43.65 (806 shares); September 30, 2024 — $50.32 (775 shares); and December 31, 2024 — $40.86 (834 shares). The value of the stock award is prorated based upon time served as a Director in any applicable quarter.

(1) Based on information contained in a Schedule 13G/A filed by BlackRock, Inc. with the SEC on January 23, 2024. As of December 31, 2023, BlackRock, Inc. had sole voting power with respect to 10,982,952 of these shares, sole dispositive power with respect to all of these shares, and shared voting and dispositive power with respect to none of these shares.
(2) Based on information contained in a Schedule 13G/A filed by The Vanguard Group with the SEC on February 13, 2024. As of December 29, 2023, The Vanguard Group had sole voting power with respect to none of these shares, sole dispositive power with respect to 10,210,283 of these shares, shared voting power with respect to 60,468 of these shares and shared dispositive power with respect to 158,617 of these shares.
(3) Based on 91,532,542 common shares outstanding as of February 28, 2025.
Stock Ownership Guidelines for Non-Employee Directors
The purpose of our stock ownership guidelines (referred to as the “Guidelines”) is to better align our Directors’ financial interests with those of our shareholders by requiring our Directors to own a minimum amount of our shares. In order to reflect the Board’s commitment to share ownership, the required share ownership level for non-employee Directors is a minimum of 12,500 shares (which amount, for 2024, is equivalent to more than four times the annual cash retainer, based on the Company's closing stock price on December 31, 2024 of $40.86).
The Directors are expected to make continuing progress towards compliance with the Guidelines and to comply fully within five years of becoming subject to the Guidelines. For purposes of our Guidelines, the following types of share ownership and equity awards are included as shares owned: common shares or time-vested restricted stock, stock units or performance shares (where the applicable performance criteria have been met), either directly or through the Company's Deferred Compensation Plan for Non-Employee Directors. As of the date of this proxy statement, all Directors either meet, or are viewed by us as on track to meet, the Guidelines. All Directors are required to retain 100% of all shares obtained through us, as compensation for services provided to us, with such percentage to be calculated after any reduction in the number of shares to be delivered as a result of any taxes and exercise costs relating to the shares (if applicable). This requirement to retain 100% of all shares obtained from us ceases once the Director has met the Guidelines, as long as the Guidelines continue to be met. Similar policies, as they relate to our Named Executive Officers, are set forth in the “Other Aspects of Our Compensation Programs” section of this proxy statement.
Delinquent Section 16(a) Reports. Section 16(a) of the Exchange Act requires that certain of our officers, our Directors and persons who beneficially own more than 10% of a registered class of our equity securities file reports of ownership and changes in ownership with the SEC. The SEC has established specific due date requirements for these reports and we are required to disclose in this proxy statement any known late filings or failures to file. Based solely on our review of Section 16 reports filed electronically with the SEC and written representations from certain reporting persons, we believe that during 2024 and for prior years, all Section 16(a) filing requirements applicable to such officers, Directors and more-than-10% shareholders were satisfied, except that one Form 4 filing reporting one 2024 RSU vesting transaction and one 2024 share-based tax withholding transaction for Ashish Khandpur was filed late (the delay in reporting these transactions was due to Company administrative error).

COMPENSATION DISCUSSION AND ANALYSIS
Compensation Discussion and Analysis
Executive Summary
This section highlights significant Compensation Committee and Company executive compensation actions that occurred in 2024. In addition, it illustrates the relationship between the compensation of our Named Executive Officers and how we measure Company performance.
Our Named Executive Officers for 2024 are:

Name | Title
Ashish K. Khandpur | President and Chief Executive Officer
Jamie A. Beggs | Senior Vice President, Chief Financial Officer
Joel R. Rathbun | Former Senior Vice President, Mergers and Acquisitions
Amy M. Sanders | Senior Vice President, General Counsel, Secretary and Corporate Ethics Officer
Christopher L. Pederson | Senior Vice President, President of Specialty Engineered Materials
Michael A. Garratt | Former Senior Vice President, President of Color, Additives and Inks, EMEA

Leadership Transitions. On April 29, 2024, Ms. Sanders was appointed as Senior Vice President, General Counsel and Secretary. Mr. Garratt retired from his roles and as an employee of the Company on July 25, 2024. On February 21, 2025, Mr. Rathbun ceased serving as an officer and employee of the Company due to the Company's change in strategic direction.
How Pay is Tied to Company Performance. Our compensation programs are designed to: (1) reward employees for generating consistent improvement in Company performance; (2) align compensation with the interests of our shareholders with the ultimate goal of improving long-term shareholder value; and (3) attract, motivate and retain talented executives. We believe that executive compensation, including both pay opportunities and pay actually earned, should be tied to Company performance, which we view in two primary ways:
•The Company’s operating performance, including results against both our long-term and short-term growth targets; and
•Return to shareholders over time.
How our compensation programs contribute to our Company’s success is described below.
Key 2024 Company Performance Results and Return to Shareholders
2024 was an important year of change for Avient. We developed and launched a new strategy to deliver and accelerate organic growth. As we began deploying our new strategy, it was important that we also remained focused on delivering performance in the present. Our overarching objective is organic topline growth with margin expansion on the bottom line and, in 2024, we delivered both.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 43

COMPENSATION DISCUSSION AND ANALYSIS
2024 Company highlights include:
•Full-year sales grew 3% to $3.24 billion, compared to $3.14 billion in 2023, which translates to 4% sales growth if the impact of foreign exchange is excluded;
•Full-year GAAP earnings per share ("EPS") from continuing operations of $1.84 in 2024, compared to $0.83 in 2023, an increase of 122%;
•Adjusted EPS increased 13% to $2.66 in 2024, compared to adjusted EPS of $2.36 in 2023(1);
•Increased our dividend on an annualized basis by 5% to $1.08; the 14th consecutive year of annual increase;
•Our safest year ever, with a record low recordable incident rate;
•Certified again as an ACC Responsible Care® organization for outstanding environmental, health, safety and security performance; and
•Received our 6th consecutive certification as a Great Place to Work® by the Great Place to Work Institute.
(1) Adjusted EPS is a financial measure that is not presented in accordance with generally accepted accounting principles ("GAAP"). See Appendix A for an explanation of management’s use of this non-GAAP financial measure and a reconciliation of this measure to its most directly comparable financial measure calculated in accordance with GAAP.
Pay-for-Performance. Our executive compensation programs reflect the belief that the amount earned by our executives must, to a significant extent, depend on achieving rigorous company and business segment objectives designed to enhance shareholder value. Looking back, and taking into account the performance achieved compared to the objectives set, we believe that our Named Executive Officers’ incentive compensation results are aligned with the operational performance that we achieved for 2024.
Results of Say-on-Pay Vote. At the 2024 Annual Meeting, we held our annual advisory vote on named executive officer compensation. Over 96% of the votes cast were in favor of this advisory proposal. The Compensation Committee considered the voting results as well as other input from conversations held with investors and viewed them as continued strong support of our executive compensation programs. As a result, the Compensation Committee made no material changes in the structure of our compensation programs or pay-for-performance philosophy in direct response to the voting results for the proposal. At the 2025 Annual Meeting, we will again hold an advisory vote to approve Named Executive Officer compensation. The Compensation Committee expects to consider the results from this year’s and future advisory votes on named executive officer compensation.
Executive Compensation Practices and Programs. The executive compensation practices and programs described below and in the accompanying tables played a vital role in driving our financial results, aligning pay with performance for 2024, and are intended to attract and retain a highly experienced, successful team to manage Avient. Our practices and programs are directly linked to our key business objectives and are designed to create value for our shareholders, including when we achieve positive operational performance.

Executive Compensation Philosophy and Objectives
Our executive compensation programs reward our officers’ performance, are specifically linked to our achievement of strategic operating and financial goals, and are designed to be competitive in the marketplace. We reward our executives for performance that meets or exceeds our strategic goals, without encouraging excessive risk-taking that could have a detrimental impact on our long-term results and the interests of our shareholders. We believe the design of our compensation plans and the relative mix of compensation elements successfully motivate our executives to improve our overall corporate performance and the profitability of the specific business segments for which they are responsible, thus maximizing shareholder value. The main objectives of our executive compensation programs are to:
•Foster a pay-for-performance culture by rewarding the achievement of specified strategic operating and financial objectives that maximize shareholder value;
•Help ensure our goals and objectives are aligned with the interests of our shareholders by recognizing and rewarding business results and the growth of our stock price through incentive programs; and
•Attract, motivate, and retain a highly qualified and successful management team to lead Avient in setting and effectively executing upon our strategic goals and objectives.
Compensation Consultant. Our executive compensation programs are approved and overseen by the Compensation Committee, which is composed entirely of independent Directors. The Compensation Committee retained the Consultant in 2024 to assist as a general matter with assessing the competitiveness and overall appropriateness of our executive compensation programs. Typically, the Compensation Committee will work with the Consultant and consider input from members of senior management to help ensure that our executives, including our Named Executive Officers, receive market competitive compensation programs that reward business results.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 45

COMPENSATION DISCUSSION AND ANALYSIS
As described below, the Consultant assisted the Compensation Committee by (1) providing comparative compensation information for management's review of base salaries, annual incentive targets and long-term incentive targets in the context of a general understanding of current compensation practices in the market, (2) providing guidance on incentive plan design, (3) monitoring and communicating trends in executive compensation to the Compensation Committee, (4) assisting with our proxy statement disclosures, and (5) assessing our Board’s compensation.
Competitive Market Pay Information. We designed our compensation programs to be competitive with companies of comparable size and industry with whom we compete for executive talent. In a typical year, we review competitive market compensation data relating to salary, annual incentives and long-term incentives. In its normal process, while the Compensation Committee does consider comparative compensation information to gain a general understanding of current compensation practices in the market, it does not benchmark or ultimately target a specific percentile or data point in assessing competitiveness for base pay or our incentive programs. Individual opportunities vary based on length of time with Avient, individual performance and level of leadership responsibility within the Company. The Compensation Committee also obtains advice and recommendations from the Consultant regarding other areas of total compensation.
In preparing competitive market data for 2024, we drew from two independent sources. We first reviewed proxy statement disclosures of a peer group of similarly-sized United States-based companies as a market check with respect to the compensation for our senior executives. This approach provided insight into current compensation practices at business competitors or companies facing similar operating challenges.
We annually evaluate the composition of our compensation peer group, giving specific consideration to company size, global presence, and specialty chemical focus. We also look at the frequency with which these companies were used as peers by other companies in our industry and which companies had identified Avient as a peer.
Each of the companies constituting our peer group for 2024 meet a majority of the primary criteria established above. The peer group (with no changes from the group used for 2023) consisted of the following 15 companies.

Avient's 2024 Peer Group for Compensation Decisions
Ashland Global Holdings Inc. | Eastman Chemical Company | RPM International Inc.
Avery Dennison Corporation | FMC Corporation | The Scotts Miracle-Gro Company
Cabot Corporation | H.B. Fuller Company | Sensient Technologies Corporation
Celanese Corporation | Hexcel Corporation | Stepan Company
The Chemours Company | Quaker Chemical Corporation | Trinseo S.A.

The second independent source of data that we used to augment the peer proxy analysis was the Consultant’s analysis of competitive market data relating to other applicable general industries. The Consultant specifically used Willis Towers Watson’s executive compensation database. To obtain comparability based on company size, the Consultant’s analysis either referenced a specific sample of comparably-sized companies or calibrated the pay of a broad sample of companies against company size. Avient did not select the companies that comprise any of these survey groups, and the component companies’ identities were not a material factor in this analysis.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 46

COMPENSATION DISCUSSION AND ANALYSIS
Review of 2024 Named Executive Officer Compensation. Management and the Compensation Committee typically review the specific pay disclosures of our peer group and the broad-based survey data provided by the Consultant. Management uses this data to develop recommendations for the Compensation Committee’s review regarding eligibility and award opportunities as well as performance measures and goals for our long-term and short-term incentive plans commencing in the following year. The Compensation Committee typically also considers this information when making compensation decisions and aligning each of the pay elements with our compensation objectives.
What We Pay and Why: Elements of Compensation
Introduction. Our executive compensation programs are designed to recognize an executive’s scope of responsibilities, leadership ability and effectiveness in achieving key performance goals and objectives. As an executive’s level of responsibility within Avient increases, so does the percentage of total compensation that is linked to performance in the form of variable compensation. Thus, the majority of the total direct compensation is performance-based and not guaranteed. We also provide various retirement and benefit programs and modest, business-related benefits. The chart below provides a picture of all elements of the total target direct compensation provided to our Named Executive Officers (also referred to as NEOs). Detailed information follows the charts below.

Base Salary |  | Annual Incentive |  | Long-Term Incentive
To attract and retain talent |  | Drives the achievement of key business results on an annual basis |  | Directly ties the interests of NEOs to our shareholders
Fixed base of cash compensation |  | Performance-based and not guaranteed |  | Helps retain key talent and a majority is performance-based and not guaranteed
Weighting 15%—CEO 28%—CFO 32%—Other NEOs |  | Weighting 18%—CEO 21%—CFO 22%—Other NEOs |  | Weighting 67%—CEO 51%—CFO 46%—Other NEOs

While the Compensation Committee typically considers comparative compensation information to gain a general understanding of current compensation practices in the market, it does not benchmark or ultimately target a specific percentile or data point in assessing competitiveness for base pay or our incentive programs. Individual opportunities vary based on length of time with Avient, individual performance and level of leadership responsibility within the Company. This strategy is consistent with our competitive market pay philosophy discussed in the “Executive Compensation Philosophy and Objectives” section of this proxy statement.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 47

COMPENSATION DISCUSSION AND ANALYSIS
2024 Base Salary. Base salaries for our Named Executive Officers are typically determined on an individual basis by the Compensation Committee after consideration of: (1) the CEO’s recommendations (for all Named Executive Officers other than the CEO); (2) breadth, scope and complexity of the executive’s role; (3) internal equity; (4) current compensation; (5) tenure in position; (6) market pay levels and trends around merit increases; and (7) individual performance.
For 2024, the Compensation Committee determined base salaries as follows, effective as of April 8, 2024: Dr. Khandpur – $1,050,000; Ms. Beggs – $600,000; Mr. Rathbun – $550,000; Mr. Pederson – $510,000; and Mr. Garratt – $510,000. In connection with her appointment as Senior Vice President, General Counsel and Secretary, Ms. Sanders' initial base salary was established at $465,000 through negotiation and generally guided by comparative compensation information as discussed above.
2024 Annual Incentive. We provided an annual cash incentive opportunity for 2024 (the "2024 Annual Incentive Program") under the 2020 Plan to (1) reward our Named Executive Officers for achieving specific performance goals that would advance our profitability, (2) drive key business results, and (3) recognize individuals based on their contributions to those results. The Named Executive Officers’ 2024 individual annual incentive opportunities (expressed as a percentage of base pay) that were approved by the Compensation Committee and effective for the 2024 Annual Incentive Program were as follows: Dr. Khandpur – 120%; Ms. Beggs – 75%; Mr. Rathbun – 75%; Ms. Sanders – 60%; Mr. Pederson – 65%; and Mr. Garratt – 65%. Dr. Khandpur and Ms. Sanders participated in this program for the first time in 2024 based on negotiations at the time they became Avient officers.
The Compensation Committee determined, after a thorough evaluation of possible plan designs and performance measures, that we would maintain generally the same fundamental annual incentive design in 2024 that we used in 2023. The Compensation Committee's evaluation demonstrated that the following metrics would be the most critical elements of Avientʼs performance:
•Adjusted Operating Income. Adjusted operating income was defined as operating income excluding special items (as noted on Appendix A).
•Working Capital as a Percentage of Sales. Working capital as a percentage of sales was calculated by taking the average 13 months of total Company working capital divided by the sum of 12 months of 2024 total Company sales, where working capital equals (1) trade accounts receivable (2) plus inventory (3) minus trade accounts payable.
•Sustainability Metrics. The specific sustainability metrics were determined by the Compensation Committee and were generally designed to: (1) improve employee safety and employee engagement; and (2) reduce energy and waste intensity.
The payouts under the 2024 Annual Incentive Program were based on attainment with respect to target goals set for each financial performance measure and, with respect to the sustainability metrics, included specific metrics for employee safety and engagement as well as energy and waste intensity. Rewardable attainment for each measure ranged from 50% (threshold) to 200% (maximum) of goal. If achievement with respect to any objective performance measure fell between the threshold and target, or between the target and maximum, earned award amounts for that particular performance measure were interpolated on a straight-line mathematical basis. If achievement with respect to any performance measure did not reach threshold, then that measure would have been deemed to have 0% attainment. The Compensation Committee made a final determination of the amount to be paid.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 48

COMPENSATION DISCUSSION AND ANALYSIS
The performance measures for the 2024 Annual Incentive Program were weighted as outlined below.
The 2024 Corporate and Business Segment Annual Plan weightings did not change from 2023. We set appropriate performance goals in 2024 under the 2024 Annual Incentive Program that focused our efforts on those factors that we believed were critical to our ongoing success, including earnings improvement, cash generation from working capital, efficiencies in our operations, and the advancement of sustainability initiatives. The 2024 performance goals were set in accordance with our strategic plan framework and annual operating plan, developed at the end of 2023. At that time, we viewed the targeted level of performance for each measure as challenging to achieve.
The threshold, target and maximum goals, attainment levels, and final payouts for each objective metric for the Named Executive Officers are set forth in the table below. Progress against the working capital as a percentage of sales metric is reflected by lower levels of working capital, so actual results that are lower than target are viewed as exceeding target performance.
As mentioned above, the sustainability metrics were based on specific targets related to employee safety and engagement as well as energy and waste intensity. Employee safety was measured through the percentage of employees who participated in two safety activities during the year. The employee engagement metric considered the results of our 2024 Great Places to Work® employee engagement survey (and whether the results resulted in certification by Great Places to Work and an improvement over the prior year’s scores). The environmental metrics considered both (1) waste to landfill intensity (Kg / MT Sales); and (2) weather adjusted energy intensity (MWh / MT Sales). The Compensation Committee determined that: (1) the employee safety and engagement objectives had been exceeded as more than 99% employees participated in at least two safety activities in 2024 and we were certified as a Great Place to Work (with improvement year-over-year in our average of all statements); and (2) the environmental objectives regarding waste to landfill intensity had been exceeded as a result of the reduction achieved, but that the objective regarding energy intensity had not been met.

Long-Term Incentive. We provide long-term incentive compensation to our Named Executive Officers to directly tie the interests of these individuals to the interests of our shareholders. We also believe that long-term incentive compensation is an important retention tool. The 2024 long-term incentive awards were granted under the 2020 Plan.
The individual long-term incentive target opportunities provided to our Named Executive Officers, which are reflected as a percentage of base salary, are typically established with consideration of our competitive market pay philosophy discussed in the “Executive Compensation Philosophy and Objectives” section of this proxy statement and intended to reward the Named Executive Officers for achieving specific performance objectives. The awards granted for 2024 under the 2020 Plan were based upon our closing stock price on February 22, 2024. The accounting value of each award was determined using the grant date of the award, February 22, 2024.
The Compensation Committee approved the following decisions with respect to the individual long-term incentive opportunities (expressed as a percentage of base salary) of the Named Executive Officers for 2024, which were in effect as of February 22, 2024 (the grant date of our annual long-term incentive awards): Dr. Khandpur – 440%; Ms. Beggs – 185%; Mr. Rathbun – 160%; Mr. Pederson – 140%; and Mr. Garratt – 140%. Dr. Khandpur participated in this annual program for the first time in 2024 based on negotiations at the time he became an Avient officer. Ms. Sanders did not participate in these 2024 long-term incentive compensation program awards. In addition, as further described below, Mr. Garratt's outstanding long-term incentive awards were modified in connection with his 2024 retirement from the Company.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 51

COMPENSATION DISCUSSION AND ANALYSIS
Awards Granted in 2024. The Compensation Committee elected to retain the same three compensation vehicles and weightings that we used in 2023 for the 2024 long-term incentive awards, which are listed below. We maintained this program design to continue to provide a balance between the relative values of the three compensation vehicles while efficiently using the shares available under the 2020 Plan. Of these three vehicles, the cash-settled performance units and the stock appreciations rights ("SARs") have performance conditions, as described in detail below. Both the cash-settled performance units and the SARs are additionally subject to time-based vesting as described in detail below. The restricted stock units (“RSUs”) are time-based awards that generally vest in their entirety on the third anniversary of the grant date.
On February 22, 2024, we granted awards under the 2020 Plan to all of our Named Executive Officers, with the exception of Ms. Sanders, who started with the Company after this date. Details regarding these awards are described below.
Cash-Settled Performance Units. Cash-settled performance units provide an opportunity for employees to receive a cash bonus if specified performance measures are met for pre-defined performance periods. The Compensation Committee maintained adjusted EPS as the performance measure for the 2024-2026 cash-settled performance unit awards in order to drive improvements in shareholder value. We use the four performance periods and relative weightings listed below to drive annual performance as well as cumulative performance. Requiring annual, as well as cumulative, performance goals helps ensure that adjusted EPS growth is a constant and visible incentive goal for our Named Executive Officers to achieve each year.

Performance Period | Weighting
January 1, 2024 through December 31, 2024 | 25%
January 1, 2025 through December 31, 2025 | 25%
January 1, 2026 through December 31, 2026 | 25%
January 1, 2024 through December 31, 2026 (cumulative) | 25%

PROXY STATEMENT 2025 | Annual Meeting of Shareholders 52

COMPENSATION DISCUSSION AND ANALYSIS
The attainment level for the cash-settled performance units will be certified at the end of the total three-year performance period. We established threshold, target and maximum adjusted EPS goals for each of the above listed performance periods. Participants earn, for the applicable performance period: (1) 100% of the target award of cash-settled performance units upon attainment of the target performance level; (2) 50% of the target award upon attainment of the threshold performance level; or (3) 200% of the target award upon attainment of the maximum (or greater) performance level. If final performance falls between the threshold and target or between target and maximum, earned award amounts will be interpolated. If threshold performance is not achieved for a particular performance period, then no award will be paid to the participants for such performance period. The cash-settled performance units do not pay out until the payment date in order to serve as a retention vehicle, and participants must generally be employed on the payment date to receive payment. The payment date will be a date in 2027 determined by the Compensation Committee (or its authorized delegate), which will occur no later than March 15, 2027.
We do not disclose the specific, forward-looking adjusted EPS goals that we established for the cash-settled performance units granted in 2024 in this proxy statement because (1) these goals relate to executive compensation to be earned and/or paid in future years and do not affect a fair understanding of the Named Executive Officers’ compensation for 2024 and (2) we believe that disclosure of such goals while the applicable performance period is ongoing would cause us competitive harm. However, we expect to disclose such goals in future proxy statements once the applicable performance periods have ended as part of our discussion and analysis about the amounts earned by the Named Executive Officers under these awards. In setting the applicable target levels, the Compensation Committee considered how achievement of the performance goals could be impacted by events expected to occur in the coming years. When establishing the specific goals for the adjusted EPS performance measure, we specifically considered how likely it will be for us to achieve the goals. We believe that the threshold goals have been established at levels that should be appropriately difficult to attain, and that the target goals will require considerable and increasing collective effort on the part of our employees, including our Named Executive Officers, to achieve. Achievement of the maximum goal is considered to be a stretch goal given current market conditions. If we attain the goals referenced above, we believe it will generate shareholder value. The performance unit grants made in 2024 for the Named Executive Officers are set forth in the 2024 Grants of Plan-Based Awards table of this proxy statement.
Stock-Settled Stock Appreciation Rights. The SARs, when exercised by the Named Executive Officers, are settled in our common shares and have an exercise price equal to the closing market price of our common shares on the grant date. However, the SARs are subject to an appreciation cap of 200% of the initial grant date closing stock price. To continually reinforce our ongoing commitment to enhancing shareholder value, the general design for the 2024 awards was to vest one-third upon the later of: (1) achieving each of the following stock price hurdles and maintaining them for twenty consecutive trading days: 10%, 15% and 20% increase, respectively, over the initial grant date closing stock price of $39.27; and (2) the satisfaction of time-based vesting requirements that lapse one-third on each of the first three anniversaries of the grant date, generally subject to the Named Executive Officer’s continued employment. For the 2024 SARs grants, each of the 10%, 15% and 20% stock price performance hurdles were met in 2024. Therefore, the 2024 SARs grants will vest upon the satisfaction of the time-based vesting requirements mentioned above. The SARs have an exercise term of ten years. The SARs granted in 2024 to the Named Executive Officers are set forth in the 2024 Grants of Plan-Based Awards table of this proxy statement.
Substantially similar SARs with different exercise prices were granted to participating NEOs in both 2022 and 2023. For the SARs granted in 2022, none of the performance hurdles were achieved through 2024. For the SARs granted in 2023, the 10% and 15% stock price performance hurdles were achieved during 2024. The SARs granted in 2022, 2023 and 2024 to the Named Executive Officers are set forth in the Outstanding Equity Awards at 2024 Fiscal Year-End table of this proxy statement.

COMPENSATION DISCUSSION AND ANALYSIS
Restricted Stock Units. RSUs are designed to promote share ownership and promote the retention of our executives. The RSUs generally vest on the third anniversary of the grant date and are set forth in the 2024 Grants of Plan-Based Awards table of this proxy statement.
Additional Award of Restricted Stock Units. On April 29, 2024, as part of her onboarding compensation package, we granted an award of 20,000 RSUs to Ms. Sanders. The RSUs generally vest on the third anniversary of the grant date and are set forth in the 2024 Grants of Plan-Based Awards table of this proxy statement. Ms. Sanders did not receive any other long-term incentive awards in 2024.
Actions Taken on Awards Granted in Prior Years. In February 2025, the Compensation Committee reviewed, certified and approved the attainment level of cash-settled performance units granted in 2022 for the three-year performance period of January 1, 2022 through December 31, 2024. The four, equally weighted performance periods listed below were used in order to drive annual as well as cumulative performance. The cash-settled performance units were earned by achieving performance goals related to our adjusted EPS over each performance period. For retention purposes, the performance units generally could not be paid until the payment date approximately three years following the date of grant as approved by Compensation Committee (or its authorized delegate). The participating Named Executive Officers received a cash payout based on achieving 14% of the target level performance for the award, reflected below.

2022–2024 Cash-Settled Performance Units Performance Measure: Adjusted EPS
Performance Periods | Weighting | Threshold | Target | Maximum | Result | Payout %
January 1, 2022 – December 31, 2022 | 25% | $2.89 | $3.26 | $3.48 | $2.93 | 55%
January 1, 2023 – December 31, 2023 | 25% | $2.34 | $2.86 | $3.49 | $1.69 | 0%

* All financial measures (performance measures and results) reported in the table above were calculated with adjustments for acquisitions, divestitures and special items (as noted on Appendix A) pursuant to the terms of the program and as approved by the Compensation Committee. Specifically, in the event of the divestiture of a business unit during the performance period, the performance measures (threshold, target, and maximum) would 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 during the portion of the performance period after the divestiture. In the event of an acquisition during the performance period, the performance measures (threshold, target, and maximum) would be adjusted to include pro forma figures for the acquired assets for the remainder of the performance period. Pro forma means target’s prior year results corresponding to remaining time left in the performance period, adjusted for purchase accounting and acquisition financing, if any. Adjusted EPS in the table above includes intangible asset amortization.
Actual payouts of the cash-settled performance units granted in 2022 to the Named Executive Officers under the 2020 Plan are set forth for 2024 in the “Non-Equity Incentive Plan Compensation” column of the 2024 Summary Compensation Table of this proxy statement.

of Control" section of this proxy statement for more information. In addition, the Compensation Committee also oversees the governance of our compensation practices. The following section describes significant activities relating to the above that occurred in 2024.
Retirement Benefits. We offer the following retirement benefits to eligible employees and eligible Named Executive Officers as specified below. Additional details about these plans, as they apply to the Named Executive Officers, are included in the “2024 Nonqualified Deferred Compensation” section of this proxy statement.
•A defined contribution retirement benefit available to eligible United States employees (as defined in the plan document) through an Internal Revenue Code tax-qualified profit sharing/401(k) plan (referred to as the “Qualified Savings Plan”); and
•An unfunded, nonqualified plan that provides benefits similar to the Qualified Savings Plan (referred to as the “Avient Supplemental Retirement Benefit Plan”), but without the Internal Revenue Code contribution and earnings limitations.
Other Benefits. We provide other benefits to the Named Executive Officers that we believe are necessary to compete for executive talent. The additional benefits for the Named Executive Officers generally consist of limited reimbursement of expenses for financial planning and tax preparation and an annual physical examination. The specific amounts attributable to the 2024 other benefits provided to the Named Executive Officers are set forth in the “All Other Compensation” column of the 2024 Summary Compensation Table of this proxy statement. The benefit allowance and reimbursement of expenses for financial planning/tax preparation are treated as taxable income to the Named Executive Officers and are not grossed up by Avient. Tax gross-ups are provided for imputed income for spouse/guest travel.
We also provide other benefits such as medical, dental, life insurance and disability coverage to each United States-based Named Executive Officer, which are identical to the benefits provided to all other eligible United States-based employees (as defined in the plan document). We provide vacation and paid holidays to all employees, including the Named Executive Officers. The Named Executive Officers were each eligible for an annualized rate of four weeks of vacation in 2024.
We also provide additional benefits to our Named Executive Officers in special circumstances, such as the payment of relocation expenses, housing, and tax preparation fees and tax equalization costs in the event of an expatriate assignment. These expatriate benefits are provided to all employees who take an international assignment. In 2024, Mr. Garratt was the only Named Executive Officer on an expatriate assignment and, as a result, received expatriate benefits under our Expatriate Policy consistent with benefits provided to other Company expatriates.
Appointment of Ms. Sanders. On April 29, 2024, Ms. Sanders was appointed as Senior Vice President, General Counsel and Secretary. In connection with her appointment, the Compensation Committee determined to provide Ms. Sanders with an initial base salary rate of $465,000 per year, a sign-on cash payment of $170,000 and the time-based grant of 20,000 RSUs described above. The sign-on cash payment and the RSUs were provided in lieu of Ms. Sanders' participation in our standard 2024 long-term incentive program award. Further, Ms. Sanders began participation in 2024 in Avient’s annual cash incentive program as described above, will begin participation in Avient's long-term equity incentive program (with a target award of 130% of annual base salary) starting in 2025, and will participate in Avient’s other standard benefits and perquisites for executive officers, including relocation services. Ms. Sanders is a party to a Management Continuity Agreement and participates in Avient’s Executive Severance Plan, and she is entitled generally to severance benefits under such arrangements pursuant to their terms, as further described below.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 55

COMPENSATION DISCUSSION AND ANALYSIS
Retirement of Mr. Garratt. On July 25, 2024, Mr. Garratt retired from the Company. See the “2024 Nonqualified Deferred Compensation” and “Potential Payments Upon Termination or Change of Control—Executive Transition Compensation” sections of this proxy statement for more information.
Departure of Mr. Rathbun. On February 21, 2025, Mr. Rathbun's service to the Company was terminated without cause due to the Company's change in strategic direction, which no longer requires the officer role in which he was serving. See the “Potential Payments Upon Termination or Change of Control—Executive Transition Compensation” section of this proxy statement for more information.
Tax Considerations. Cash compensation, such as base salary and annual incentive compensation, is taxable to the recipient as ordinary income when earned, unless deferred under a company-sponsored deferral plan. Deferrals under Internal Revenue Code tax-qualified plans, such as a 401(k) plan, do not affect our current tax deduction. Deferrals under supplemental executive deferral plans delay our tax deduction until the deferred amount (and any accumulation thereon) is paid. Stock-settled SARs are generally taxable as ordinary income when exercised, RSUs are generally taxable as ordinary income when they vest, and cash-settled performance units are generally taxable as ordinary income when paid. We generally realize a tax deduction at those specified times, except where limited by Code Section 162(m), which generally disallows a federal income tax deduction to publicly traded companies like Avient for compensation in excess of $1 million per year paid to certain current and former executive officers. The Compensation Committee reviews potential tax implications before making decisions regarding compensation.
Accounting Considerations. When reviewing preliminary recommendations and in connection with approving the terms of a given incentive plan period, management and the Compensation Committee review and consider the accounting implications of a given award, including the estimated expense and dilutive considerations. With consideration of the accounting treatment associated with an incentive plan design, management and the Compensation Committee may alter or modify the incentive award if the award (and the related accounting consequences) were to adversely affect our financial performance.
Stock Ownership and Retention Guidelines. In order to better align the financial interests of our executives with those of our shareholders, we believe our executives should own a meaningful number of Avient common shares. We have adopted Guidelines specifying a minimum level of stock ownership for all executives, including all Named Executive Officers.
The current Guidelines require all executives, including the continuing Named Executive Officers, to retain 100% of all net shares obtained through Avient as compensation for services provided. This requirement will cease when the Guidelines have been met, provided that an officer can only divest of a number of shares such that the Guidelines continue to be met. In general, shares counted toward required ownership include shares directly and indirectly held, shares and phantom shares held in our retirement or deferral plans, and RSUs and performance shares (if the applicable performance measures are met). The specific levels of stock ownership for the continuing Named Executive Officers are noted in the following table. Executives are expected to
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 56

COMPENSATION DISCUSSION AND ANALYSIS
accumulate the specified shares within five years of their becoming subject to the Guidelines. These policies, as they relate to our Directors, are discussed in the “Stock Ownership Guidelines for Directors” section of this proxy statement.

Name | Stock Ownership Target (in shares) | Total Share Ownership as of February 28, 2025
Ashish K. Khandpur | 125,000 | 224,575
Jamie A. Beggs | 45,000 | 86,103
Amy M. Sanders | 20,000 | 25,853
Christopher L. Pederson | 20,000 | 59,314

Timing with Respect to Equity Award Grants. We have adopted a policy with respect to the timing of the grant of equity awards (including grants to the Named Executive Officers), which policy provides that equity awards (including common stock, SARs and RSUs) are granted pursuant to approval by the Board or the Compensation Committee, or pursuant to authority delegated by the Board or the Compensation Committee to the Chief Executive Officer. Such grants generally are made at times when Avient is not in possession of material non-public information, and not during a “blackout period,” which is the period of time that is in close proximity to the release of financial or material non-public information. The policy further provides that, to the extent practicable, annual grants to existing employees should be approved at regularly scheduled meetings and that the grant price for any stock option or SAR shall not be less than the fair market value of Avient’s common shares on the grant date (which is generally defined as the closing price of our common shares on the grant date). Annual grant approvals typically occur in February of each year.
As a general matter, the Compensation Committee does not take material nonpublic information into account when determining the timing and terms of such awards. The grant process and timing described above is used to provide for a routine and regular grant practice regarding annual awards (including annual SARs), and in order to make sure that the existence (or lack thereof) of material non-public information is not a material factor in decisions about the timing or size of SARs grants. Similarly, Avient has not timed the disclosure of material non-public information for the purpose of affecting the value of executive compensation. During 2024, the Company did not grant SARs to any Named Executive Officer during any period beginning four business days before and ending one business day after the filing of any Company periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any Company Form 8-K that disclosed any material non-public information.
Clawback Policy. The Company maintains and operates a Compensation Clawback Policy, which provides for the reasonably prompt recovery (or clawback) of certain excess incentive-based compensation received during an applicable three-year recovery period by current or former executive officers in the event Avient is required to prepare an accounting restatement due to the material noncompliance with any financial reporting requirement under the securities laws. Triggering events include accounting restatements to correct an error in previously issued financial statements that is material to such previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. Excess incentive-based compensation for these purposes generally means the amount of incentive-based compensation received (on or after October 2, 2023) by such executive officer that exceeds the amount of incentive-based compensation that would have been received by such executive officer had it been determined based on the restated amounts, without regard to any taxes paid. Incentive-based compensation potentially subject to recovery under the mandatory accounting restatement provisions of the Compensation Clawback Policy is generally limited to any compensation granted, earned or vested based wholly or in part on the attainment of one or more financial reporting measures.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 57

COMPENSATION DISCUSSION AND ANALYSIS
In general, Avient may utilize a broad range of recoupment methods under the Compensation Clawback Policy for mandatory accounting restatement clawbacks. The Compensation Clawback Policy does not condition such clawback on the fault of the executive officer, but Avient is not required to clawback amounts in limited circumstances where the Compensation Committee has made a determination that recovery would be impracticable and (1) Avient has already attempted to recover such amounts but the direct expense paid to a third party in an effort to enforce the Compensation Clawback Policy would exceed the amount to be recovered, (2) the recovery of amounts would violate applicable home country law, or (3) the recovery would likely cause the non-compliance of a tax-qualified retirement plan under the Internal Revenue Code of 1986, as amended, and applicable regulations. Operation of the mandatory accounting restatement provisions of the Compensation Clawback Policy is subject to a brief phase-in process during the first few years after its effectiveness. Avient may not indemnify any such executive officer against the loss of such recovered compensation in the event of a mandatory accounting restatement.
Further, Avient continues to maintain a predecessor compensation clawback policy (the “Prior Clawback Policy”). The Prior Clawback Policy remains operational and applies to individuals and/or compensation not covered by or subject to the NYSE-compliant Compensation Clawback Policy. The Prior Clawback Policy will apply on a permissive basis in the event of an applicable accounting restatement plus qualifying misconduct that contributed to the accounting restatement (in which case Avient may require an executive officer to repay all incentive-based compensation that he or she received in excess of what would have been paid if the restated financial statements had originally been prepared without such material accounting restatement).
Insider Trading Policy. We have adopted an Insider Trading Policy and procedures applicable to our Directors, officers, and employees, and have implemented processes for the Company, that we believe are reasonably designed to promote compliance with insider trading laws, rules, and regulations, and the NYSE listing standards in connection with the purchase, sale and/or other dispositions of our securities.
Prohibition on Hedging and Pledging Our Securities. Our Insider Trading Policy prohibits Directors, officers and certain other employees of Avient from engaging in any speculative transactions involving Avient securities, including: (1) buying or selling options, warrants, puts or calls or similar instruments; (2) short sales; or (3) margin purchases of Avient securities.
Subsequent Events. In 2024, we updated our incentive plan designs for fiscal year 2025 to align and support our new Company strategy. We expect to disclose further details of our 2025 incentive plan design in the 2026 proxy statement.

(1) Compensation for Dr. Khandpur is provided only for 2024 and 2023 because he was not a Named Executive Officer in 2022.
(2) On July 25, 2024, Mr. Garratt retired from the Company. In consideration of Mr. Garratt's contributions to the Company, and in exchange for a release of claims from Mr. Garratt, an extension of Mr. Garratt's post-employment non-competition and non-solicitation covenants for an additional year, and his commitment to provide transition support to the Company, Mr. Garratt’s outstanding and unvested long-term incentive awards were modified to waive the continued employment requirements for such awards (rather than having such awards continue to vest on just a pro-rata basis); such awards are otherwise governed by the standard terms of each award and tax code requirements, including any performance criteria. For details regarding the modified awards, refer to the 2024 Grants of Plan-Based Awards table of this proxy statement. Mr. Garratt retained his vested equity awards upon his retirement, which were then governed by the standard terms of each award. The incremental fair value of the modified awards is $432,186 for the stock awards and $357,464 for the option awards.
Bonus (column (d))
The amounts reported in the “Bonus” column relate to, for 2024, sign-on compensation consisting of a cash payment of $170,000 to Ms. Sanders in connection with her service as Senior Vice President, General Counsel and Secretary, and for 2023, sign-on compensation consisting of a cash payment of $1,500,000 to Dr. Khandpur in connection with his service as President and Chief Executive Officer of the Company.

Avient cautions that the amounts reported for these awards may not represent the amounts that the Named Executive Officers will actually realize from these awards. To what extent a Named Executive Officer realizes value will depend on our stock price and continued employment. The value actually realized upon a vesting of RSUs for the Named Executive Officers in 2024 is reflected in the 2024 Option Exercises and Stock Vested table of this proxy statement.
Option Awards (column (f))
The amounts reported in the “Option Awards” column consist of, for 2024, stock-settled SARs (with time and performance based vesting requirements as well as a SAR appreciation cap) that were granted to the Named Executive Officers in 2024. The amounts reported for 2024 represent the grant date fair value of the SARs granted to each of the Named Executive Officers, calculated in accordance with FASB ASC Topic 718. Accordingly, this column includes amounts for awards that have not yet vested. For information regarding the assumptions used in determining the fair value of these awards, please refer to Note 13, Share-Based Compensation, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

(3)Stock Appreciation Rights. These amounts represent stock-settled SARs granted to the Named Executive Officers on February 22, 2024 as part of our 2024 long-term incentive award under the 2020 Plan, as further described in the “Awards Granted in 2024” section of the “Compensation Discussion and Analysis.” The SARs are subject to an appreciation cap of 200% of the initial grant date closing stock price. “Threshold” represents one-third of the SAR award, which is the amount that would be eligible to vest after achieving only the first stock price hurdle applicable to the award. Target refers to the number of shares underlying the SARs that will be eligible to vest upon satisfaction of all of the stock price hurdles applicable to the award. The SARs do not have a “maximum” level of attainment as a participant cannot receive SARs in excess of the initial award.
(4)Modification of Stock Appreciation Rights in Connection with Retirement. In consideration of Mr. Garratt's contributions to the Company, and in exchange for a release of claims from Mr. Garratt, an extension of Mr. Garratt's post-employment non-competition and non-solicitation covenants for an additional year, and his commitment to provide transition support to the Company, Avient modified certain SAR awards previously granted to Mr. Garratt that would have otherwise been forfeited under the terms of the applicable grant agreements. The values shown for the modified SARs represent the unvested portion of the following: 20,600 SARs originally granted on February 22, 2024 (row four), 18,800 SARs originally granted on February 17, 2023 (row five), and 16,000 SARs originally granted on February 14, 2022 (row six). The modifications were based upon the period of time that Mr. Garratt was employed by Avient from the original grant date of the award through July 22, 2024 (the modification date).
All Other Stock Awards: Number of Shares of Stock or Units (RSUs) (column (h))
(5)Grant of RSUs. This amount represents an April 29, 2024 grant of stock-settled RSUs to Ms. Sanders. The RSUs have dividend equivalent rights that entitle the grantee to dividend equivalents on each share of our common stock underlying the award equal to the dividend per share declared and paid on our issued and outstanding shares of common stock. The dividend equivalent rights are subject to the same restrictions as the underlying RSUs. This grant is is described in the "What We Pay and Why: Elements of Compensation" section of this proxy statement.
(6)Annual Grant of RSUs. These amounts represent stock-settled RSUs granted to the Named Executive Officers on February 22, 2024 as part of our 2024 long-term incentive award under the 2020 Plan, as further described in the “Awards Granted in 2024” section of the “Compensation Discussion and Analysis.” The RSUs have dividend equivalent rights that entitle the grantee to dividend equivalents on each share of our common stock underlying the award equal to the dividend per share declared and paid on our issued and outstanding shares of common stock. The dividend equivalent rights are subject to the same restrictions as the underlying RSUs.
(7)Modification of RSUs in Connection with Retirement. In consideration of Mr. Garratt's contributions to the Company, and in exchange for a release of claims from Mr. Garratt, an extension of Mr. Garratt's post-employment non-competition and non-solicitation covenants for an additional year, and his commitment to provide transition support to the Company, Avient modified certain RSU awards previously granted to Mr. Garratt that would have otherwise been forfeited under the terms of the applicable grant agreements. The values shown for the modified RSUs impact the following: 6,400 RSUs originally granted on February 22, 2024 (row eight), 5,550 RSUs originally granted on February 17, 2023 (row nine), and 4,550 RSUs originally granted on February 14, 2022 (row ten). The modifications were based upon the period of time that Mr. Garratt was employed by Avient from the original grant date of the award through July 22, 2024 (the modification date).
Exercise or Base Price of Option Awards (column (i))
In setting the base price of these SARs, we followed the practice of using our closing stock price on the grant date. This practice complies with the 2020 Plan.
Grant Date Fair Value of Stock and Option Awards (column (j))
The amounts in this column represent the grant date fair value of each equity-based award, computed in accordance with FASB ASC Topic 718. For information regarding the assumptions used in determining the fair value of an award, please refer to Note 13, Share-Based Compensation, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

(1)Amounts in these columns represent stock-settled SARs that vest in one-third increments, with each one-third increment vesting on the later of (a) the first, second and third anniversary of the grant date, respectively and (b) the achievement of a stock price hurdle (based on Avient’s closing stock price and sustained for thirty consecutive trading days for all grants except the February 17, 2023 and February 22, 2024 grants for which the stock price hurdle must be sustained for twenty consecutive trading days) applicable to that increment. As of December 31, 2024, all stock price hurdles have been met for all SAR grants made prior to 2022, none of the stock price hurdles have been met for the 2022 SAR grants, two out of three stock price hurdles have been met for the 2023 SAR grants, and all three stock price hurdles have been met for the 2024 SAR grants. SAR grants for which stock price hurdles have been met vest in one-third increments on the first, second and third anniversary of the grant date.
(2)Amounts in this column represent stock-settled RSU awards that generally vest in full on the third anniversary of the grant date, with the exception of the December 1, 2023 grant to Dr. Khandpur which vests ratably over four years. The awards include shares deemed purchased with reinvested dividend equivalents that are subject to the same forfeiture conditions as the shares to which the dividends

relate. The amounts in this column include all dividend equivalents declared from 2022 through 2024 attributable to the awards (including the fourth quarter dividend declared on October 9, 2024 to shareholders of record on December 13, 2024, which was paid on January 8, 2025).
(3)On July 25, 2024, Mr. Garratt retired from the Company. In consideration of Mr. Garratt's contributions to the Company, and in exchange for a release of claims from Mr. Garratt, an extension of Mr. Garratt's post-employment non-competition and non-solicitation covenants for an additional year, and his commitment to provide transition support to the Company, Mr. Garratt’s outstanding and unvested long-term incentive awards were modified to waive the continued employment requirements for such awards (rather than having such awards continue to vest on just a pro-rata basis); such awards were otherwise governed by the standard terms of each award and tax code requirements, including any performance criteria. For details regarding the modified awards, refer to the 2024 Grants of Plan-Based Awards table of this proxy statement. Mr. Garratt retained his vested equity awards upon his retirement, which were then governed by the standard terms of each award.

Option Awards (columns (b) and (c))
Column (b) reports exercises of SARs during 2024 on an aggregate basis. The value realized on exercise (column (c)) was computed based on the difference between the closing stock price of the underlying securities at exercise and the base price of the SARs. The number of SARs withheld to cover taxes and the exercise price, and the net number of shares acquired as a result of SAR exercises during 2024 is as follows: Mr. Rathbun - 5,765 SARs and 9,261 shares; and Mr. Garratt - 1,552 SARs and 4,016 shares.
Stock Awards (columns (d) and (e))
Column (d) reports the vesting of RSUs during 2024 on an aggregate basis. For all applicable Named Executive Officers except Dr. Khandpur, the stock awards include RSUs that were granted on February 8, 2021 and vested on February 8, 2024. For Dr. Khandpur, the stock awards reflect RSUs that were granted in recognition of his appointment as President and Chief Executive Officer on December 1, 2023, and which vest which vests ratably over four years. The amounts in these columns include shares awarded through a dividend equivalent feature under the applicable award.
The value realized on vesting (column (e)) was computed by multiplying the number of vested RSUs, including the corresponding dividend equivalents, by the closing stock price of the underlying securities on the vesting date. The number of shares withheld to cover taxes is as follows: Dr. Khandpur - 13,113; Ms. Beggs - 3,374; Mr. Rathbun - 2,552; Mr. Pederson - 1,668; and Mr. Garratt - 8,804.
2024 Non Qualified Deferred Compensation
We offer a defined contribution retirement benefit to all eligible Avient employees through the Qualified Savings Plan. The Qualified Savings Plan provides employees with individual retirement accounts funded by contributions including an employer-paid match on employee contributions equal to 100% of the first 3% of earnings the employee contributes plus 50% of the next 3% of earnings the employee contributes. The Internal Revenue Code limits employee contributions to the Qualified Savings Plan to $23,000 ($30,500 for participants over age 50), and earnings upon which employee/employer contributions may be made are limited to $345,000 in 2024.
We currently offer participation in a non qualified deferred compensation retirement plan, called the Avient Supplemental Retirement Benefit Plan ("Supplemental Plan"), to specified employees that include the Named Executive Officers. This plan is an unfunded, non qualified plan that provides benefits similar to our Qualified
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 65

EXECUTIVE COMPENSATION
Savings Plan, but without Internal Revenue Code contribution and earnings limitations. The Named Executive Officers are permitted to elect to defer up to 90% of their salary and annual bonus between the Qualified Savings Plan and the Supplemental Plan. The amounts deferred are credited to accounts selected by the Named Executive Officer that generally mirror the investment alternatives available in our Qualified Savings Plan except for an interest crediting fund based on corporate bond yields limited to 120% of the applicable federal rate. Each Named Executive Officer who participates in the Avient Supplemental Retirement Benefit Plan is 100% vested in that portion of their account that is attributable to elective deferrals and the Company match. A Named Executive Officer’s vested Supplemental Plan accounts will commence to be paid to them within 30 days of the date of their termination of employment with us in the form of payment they selected (lump-sum payment or payment in installments over a period not exceeding 10 years) on an election form received by us. The Avient Supplemental Retirement Benefit Plan is also subject to the rules of Code Section 409A, which restricts the timing of distributions. Thus, payment, or commencement of payment, to the Named Executive Officers of their accounts may need to be delayed by six months following their separation from service with us.
In 2019, our Board approved an amendment to the Avient Supplemental Retirement Benefit Plan to add a Company stock fund investment feature to mirror the investment alternatives available under the Qualified Savings Plan. This feature also provides for deemed reinvestment of dividend equivalents on amounts attributed to the Company stock fund. The plan requires the payout of balances deemed invested in the Company stock fund at the time of distribution to be in the form of Company common shares (or cash for fractional shares).

Potential Payments Upon Termination or Change of Control
Summary of Potential Payments
Our plans, agreements, arrangements or typical practices would provide severance benefits to our still-serving Named Executive Officers in varying amounts to the executive under certain scenarios. We do not have employment agreements with our Named Executive Officers. We do have management continuity agreements
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 66

EXECUTIVE COMPENSATION
(“Continuity Agreements”) with each of our continuing Named Executive Officers that provide for specified benefits upon a termination of employment following a change of control, and each of our continuing Named Executive Officers participates in our Executive Severance Plan. Further, other Company plans, agreements and arrangements may provide for specified benefits upon a change of control (or for acceleration of such benefits). Severance and other benefits that are payable upon a termination of employment or upon a change of control are described below. The table following this narrative discussion summarizes the amounts payable upon termination or a change of control under certain circumstances to our Named Executive Officers who were still serving on December 31, 2024, assuming that the executive’s employment terminated on December 31, 2024.
Management Continuity Agreements
We have entered into Continuity Agreements with all of our elected corporate officers, including each of the Named Executive Officers. The Continuity Agreements serve to encourage key executives to carry out their duties and provide continuity of management in the event of a “change of control” of Avient. The participating Named Executive Officers are provided with severance protection for a period of three years (for Dr. Khandpur) and two years (for Messrs. Rathbun and Pederson, and Mses. Beggs and Sanders) should their employment be terminated either by us without cause or by the executive for good reason following a change of control. The Continuity Agreements are automatically renewed each year unless we give prior notice of termination and do not provide any assurance of continued employment. For these purposes, “change of control”, “cause” and “good reason” have the meanings ascribed to such terms in the Continuity Agreements. Mr. Garratt was also a party to a Continuity Agreement under terms similar to those for Mr. Pederson during his employment.
If a change of control occurs and the participating Named Executive Officer’s employment is terminated by us or a successor for reasons other than “cause” or is terminated voluntarily by the individual for “good reason,” in each case during the severance protection period, then the Continuity Agreements generally provide that the individual would be entitled to receive:
•A lump-sum payment equal to two or three years (depending on the executive) of the base salary in effect immediately prior to the change of control, or if greater, on the termination date;
•A lump-sum payment equal to two or three times (depending on the executive) the executive’s targeted annual incentive amount, as that term is defined the Continuity Agreement, in effect prior to the change of control;
•Employee health and welfare benefits (excluding the long-term disability plan) for up to two or three years (depending on the executive) at active employee rates;
•An allowance equal to one year of financial planning/tax preparation that the executive was entitled to receive prior to the change of control; and
•A lump-sum payment equal to the employer contributions required to be made to certain retirement plans on behalf of the executive for the year of the change of control or the year of termination.
None of the agreements contain a single trigger or a modified single trigger for benefits. The Continuity Agreements do not provide for benefits upon death or disability following a change of control. The Continuity Agreements also do not provide for tax gross-ups for any excise taxes due under the Internal Revenue Code for any so-called “golden parachute” payments made under the agreements (except for Named Executive Officers with “grandfathered” Continuity Agreements). As of 2024, no continuing Named Executive Officers have grandfathered Continuity Agreements.
To the extent a payment or benefit that is paid or provided under a Continuity Agreement would also be paid or provided under the terms of another plan, program, agreement, arrangement or legal requirement, the executive would be entitled to payment under the Continuity Agreement or such other applicable plan,
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 67

EXECUTIVE COMPENSATION
program, agreement, arrangement or legal requirement, whichever provides for greater benefits, but would not be entitled to benefits under both the Continuity Agreement and such other plan, program, agreement, arrangement or legal requirement.
In addition, in order to receive payment and benefits under the Continuity Agreement, the participating Named Executive Officer must execute a release of claims against Avient and comply with confidentiality, non-compete and non-solicitation covenants for two or three years, depending on the executive.
Executive Severance Plan
The Compensation Committee has adopted the Executive Severance Plan. The Executive Severance Plan provides for severance payments upon certain terminations of employment to our Named Executive Officers and other elected officers who are expected to make substantial contributions to our success and thereby provide for stability and continuity of operations.
The Executive Severance Plan provides that, if Avient terminates the employment of a Named Executive Officer for any reason other than Cause (as defined in the Executive Severance Plan), death or disability, then the Named Executive Officer will be entitled to receive:
•Salary continuation payments in an amount equal to two times the Named Executive Officer’s base salary;
•A payment in an amount equal to the Named Executive Officer’s annual bonus under the annual incentive program as earned for the year in which the separation occurs;
•Reimbursement for the costs previously paid by us for continued coverage for two years in our medical, dental and vision plans, plus any taxes imposed as a result of such reimbursement; and
•Fees for outplacement benefits for a period of 12 months.
We do not have to make payments to Named Executive Officers under the Executive Severance Plan if they are entitled to receive payment under a Continuity Agreement discussed above. In addition, in order to receive payments under the Executive Severance Plan, the Named Executive Officer must execute a release of claims against us and is subject to confidentiality, non-compete, non-solicitation and non-disparagement covenants during the two-year severance period.
Long-Term Incentive Awards
Each of the grant agreements evidencing outstanding awards of RSUs, SARs, cash-settled performance units and performance shares provides that the vesting of such award will accelerate upon a change of control. In the event of a change of control, cash-settled performance units for which all performance periods are completed as of December 31, 2024 are valued at actual attainment, and cash-settled performance units for which all performance periods are not completed as of December 31, 2024 are valued at target attainment. For this purpose, a “change of control” is defined in the applicable equity compensation plan.
The grant agreements also provide for prorated vesting upon death, disability and retirement, as those terms are defined in the grant agreements. In the case of such prorated vesting, cash-settled performance units are generally valued based on actual performance for the applicable performance period (which, for performance periods that were not completed as of December 31, 2024, we have assumed to be target performance for purposes of the table below). Also in the case of such prorated vesting, SARs generally only vest if the performance hurdles have been met as of the date of death, disability or retirement, except that SARs granted in 2018 and later remain eligible to vest if the performance hurdles are satisfied after such termination event.

In connection with Mr. Garratt's retirement on July 25, 2024, he was entitled to retain his vested equity awards (governed by the standard terms of each award) and receive certain other benefits accrued and vested under the standard terms and conditions of the plans in which he participated. See the "2024 Nonqualified Deferred Compensation" section of this proxy statement for more information. In consideration of Mr. Garratt's contributions to the Company, and in exchange for a release of claims from Mr. Garratt, an extension of Mr. Garratt's post-employment non-competition and non-solicitation covenants for an additional year, and his commitment to provide transition support to the Company, Mr. Garratt's outstanding and unvested long-term incentive awards were modified to waive the continued employment requirements for such awards (rather than having such awards continue to vest on just a pro-rata basis); such awards are otherwise governed by the standard terms of each award and tax code requirements, including any performance criteria. The incremental fair value of the modified awards is $432,186 for the stock awards and $357,464 for the SARs awards. For details regarding the modified awards, refer to the 2024 Grants of Plan-Based Awards table of this proxy statement.
Further, on February 21, 2025, Mr. Rathbun’s service to the Company was terminated without cause due to the Company’s change in strategic direction, which no longer requires the officer role in which he was serving. In connection with this departure, Mr. Rathbun will receive (in exchange for a release of claims and continued compliance with applicable restrictive covenants): (1) salary continuation payments of approximately $1,128,209 (including $28,209 in earned but unused vacation); (2) payout under his 2025 Annual Incentive Program award based on actual performance; (3) reimbursement (plus tax gross-up) for two years of continued health coverage under our plans (see table above for value); and (4) 12 months of outplacement benefits (see table above for value). Further, in recognition of Mr. Rathbun's contributions to the Company, and in exchange for an extension of Mr. Rathbun’s post-employment non-competition and non-solicitation covenants for an additional year, plus his commitment to provide consulting support to the Company, the Compensation Committee approved pro-rata continued vesting of his outstanding RSUs, in accordance with the other terms of such awards, upon his departure. The intrinsic value of such modified RSUs is approximately $312,812.
CEO Pay Ratio Disclosure
The SEC has adopted rules requiring annual disclosure of the ratio of the median employee’s annual total compensation to the annual total compensation of the CEO.
CEO (Khandpur) Annual Total Compensation for 2024 - $6,903,295
Median Employee Annual Total Compensation for 2024 - $61,504
Ratio of CEO (Khandpur) to Median Employee Annual Total Compensation for 2024 - 112:1
How the Median Employee was Determined
For purposes of this pay ratio disclosure, we determined that it was appropriate to continue using the same median employee that we identified for 2022, as there has been no change in our employee population or
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 71

EXECUTIVE COMPENSATION
employee compensation arrangements that we believe would result in a significant change in the pay ratio disclosure. In determining the median employee, we used a consistently applied compensation measure (“CACM”) for all employees (other than the CEO) included in the determination. Our CACM was annual salary plus annual target cash incentive. To determine the median employee, all global employees as of December 31, 2022 were evaluated. This group of employees did not include any independent contractors or workers who provided leased services, and did not exclude any employees of businesses acquired by us or combined with us. Further, we did not utilize any statistical sampling or cost-of-living adjustments for purposes of determining our median employee. A portion of our employee workforce (full-time and part-time) identified above worked for less than the full fiscal year due to commencing employment after January 1, 2022. In determining the median employee, we annualized the total compensation for such individuals by extending their base wages over the full annual period but avoided creating full-time equivalencies.
The global employee evaluation focused on each employee’s annual salary and annual target cash incentive for the period January 1, 2022 to December 31, 2022. Annual salary for employees outside of the United States was converted to United States Dollars by applying the applicable exchange rates in effect on December 31, 2022. The annual salary and annual target cash incentive amounts were then added together to determine each employee’s CACM. Using this methodology, we determined that our median employee for 2022 was a full-time employee working at a manufacturing facility in Phoenix, Arizona and the stated Median Employee Annual Total Compensation set forth above is the sum of such employee's actual 2024 annual salary and actual 2024 annual cash incentive amount. We note that, due to our permitted use of reasonable estimates and assumptions in preparing this pay ratio disclosure, the disclosure may involve a degree of imprecision, and thus this pay ratio disclosure is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions described above.
Pay Versus Performance Disclosure
We are providing the following information about compensation for our Named Executive Officers serving during each of 2020, 2021, 2022, 2023 and 2024 (each, a "Covered Year"), as well as results for certain elements of financial performance during those same Covered Years.
We have consistently over the Covered Years linked our Named Executive Officers’ variable incentive compensation to financial and operational performance measures that help us achieve our pay for performance philosophy, which is to: (1) reward employees for generating consistent improvement in Company performance; (2) align compensation with the interests of our shareholders with the ultimate goal of improving long-term shareholder value; and (3) attract, motivate and retain talented executives.
More specifically, we design executive compensation to be linked to Company operating performance (including results against both our long-term and short-term growth targets) and return to shareholders over time. The following Tabular List provides what we believe represent the most important financial performance measures we used to link compensation for our Principal Executive Officer (“PEO“) and non-PEO Named Executive Officers for fiscal 2024 to our performance:

PROXY STATEMENT 2025 | Annual Meeting of Shareholders 72

EXECUTIVE COMPENSATION
In our long-term incentive program, we tie three-year achievement of cash settled performance units to adjusted EPS and therefore, our company selected measure for purposes of this pay for performance disclosure is annual adjusted EPS, and we have included it in the Pay Versus Performance (“PVP”) Table below.
The PVP Table provides information about compensation, including “compensation actually paid” (or “CAP”), for our Named Executive Officers serving during each Covered Year, as well as results for the following external financial metrics during those same Covered Years: our total shareholder return (“TSR”) results; Peer Group (as defined below) TSR results; and GAAP net income results. The PVP Table also contains information on the relationship between Named Executive Officer pay and our Company-selected financial performance measure for the PVP Table, adjusted EPS. For 2024, we view annual adjusted EPS to be the most important metric for implementation of our pay for performance philosophy.

(1) Robert M. Patterson was our principal executive officer (“First PEO”) for the full year for each of 2022, 2021 and 2020. For 2023, Mr. Patterson was our First PEO from January 1 - December 1. Dr. Ashish Khandpur was our principal executive officer ("Second PEO") from December 1, 2023 - December 31, 2023 and for all of 2024. For 2024, our non-PEO named executive officers were Jamie A. Beggs, Joel R. Rathbun, Amy M. Sanders, Christopher L. Pederson, and Michael A. Garratt. For 2023, 2022 and 2021, our non-PEO named executive officers were Jamie A. Beggs, Michael A. Garratt, Lisa K. Kunkle, and Joel R. Rathbun. For 2020, our non-PEO named executive officers were Jamie A. Beggs, Michael A. Garratt, M. John Midea, Lisa K. Kunkle, and Bradley C. Richardson.
(2) For 2024, in determining both the CAP to our PEO and the average CAP to our non-PEO named executive officers for purposes of this PVP Table, we deducted from or added back to the total amounts of compensation reported in columns (b) or (d), as applicable the following amounts. Please note that, while similar adjustment information was provided in our 2024 proxy statement for Covered Year 2023 and in our 2023 proxy statement for Covered Years 2020, 2021 and 2022, under applicable SEC guidance, repeating such adjustment information is not required in this proxy statement because in our view it is not material to our stockholders’ understanding of the information reported in the table above for 2024 or the relationships disclosure provided below:

PROXY STATEMENT 2025 | Annual Meeting of Shareholders 73

EXECUTIVE COMPENSATION
(3) For each Covered Year, our total shareholder return was calculated as the yearly percentage change in our cumulative total shareholder return on our common stock, par value $0.01 per share, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on the New York Stock Exchange (“NYSE”) on December 31, 2019 through and including the last day of the Covered Year (each one-year, two-year, three-year, four-year and five-year period, a “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of the Measurement Period to produce the Covered Year-end values of such investment as of the end of 2024, 2023, 2022, 2021 and 2020, as applicable. Because Covered Years are presented in the table in reverse chronological order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.
(4) For purposes of this pay versus performance disclosure, our peer group is the S&P 400 Chemicals index (the "Peer Group"). For each Covered Year, our peer group cumulative total shareholder return was calculated based on a deemed fixed investment of $100 through the Measurement Period, assuming dividend reinvestment.
(5) Adjusted EPS is calculated as net income, adjusted for special items (as noted in Appendix A), divided by weighted-average diluted shares.
Descriptions of Relationships Between CAP and Certain Financial Performance Measure Results
The following charts provide, across the Covered Years, a description of the relationships between (1) our cumulative TSR and the cumulative TSR for the Peer Group reflected in the PVP Table above, (2) PEO CAP (for the First PEO and the Second PEO) and the financial performance measures results for TSR, net income, and adjusted EPS as set forth in the PVP Table above, and (3) non-PEO named executive officer average CAP and the financial performance measures results for TSR, net income, and adjusted EPS as set forth in the PVP Table above.
As is reflected below, and unless otherwise explained below, Company performance was generally in line with PEO CAP and non-PEO named executive officer average CAP trends from year to year (as applicable), and we believe that the relationships below demonstrate that our Named Executive Officer compensation is commensurate with performance over the Covered Years.
Net Income versus Compensation Actually Paid

|  |  |  |  |  |  | First PEO |  |  |  | Second PEO |  |  |  | Average Non-PEO Named Executive Officer |  |  |  | Net Income

Net Income versus Compensation Actually Paid. Net income includes the income from discontinued operations, and for 2022 includes a one time $550 million gain on the sale of our Distribution business.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 74

EXECUTIVE COMPENSATION
Therefore, in 2022, net income is not heavily correlated with named executive officer compensation because this gain is not reflective of the underlying performance of the Company.

EXECUTIVE COMPENSATION
Adjusted EPS versus Compensation Actually Paid. Named executive officer compensation has either tracked or, in the case of 2022, significantly lagged our performance as compared to adjusted EPS over the Covered Years.
Compensation Committee Interlocks and Insider Participation
During 2024, Robert E. Abernathy, Richard H. Fearon, Ernest Nicolas, Kerry J. Preete, and William A. Wulfsohn served on the Compensation Committee. None of our executive officers was a member of the Board of Directors or compensation committee of any other company where the relationship would be construed to constitute a committee interlock within the meaning of the rules of the SEC during 2024.
Risk Assessment of the Compensation Programs
As part of the Compensation Committee’s annual governance process, in October 2024 we conducted a formal assessment of our compensation programs to help confirm that they do not create risks that are reasonably likely to have a material adverse effect on Avient. With guidance from the Consultant, our Internal Audit and Human Resources groups completed the initial risk assessment of our compensation programs, including those that extend beyond the executive officers. The assessment was reviewed by our legal department and the Consultant, with these groups providing additional analysis and validation of the results. The results of the compensation risk assessment were presented to the Compensation Committee at its October 2024 meeting. The areas we considered in determining that our compensation programs do not pose a material risk to Avient included our:

Compensation Philosophy | Payout Curves | Clawback Policy
Compensation Plan Design | Weightings of Incentive Plan Measures | Anti-Hedging/Anti-Pledging Policies
Balanced Pay Mix | Compensation Plan Governance and Oversight | Stock Ownership Requirements
Timing on Incentive Payouts | Selection of Performance Measures | Pay-for-Performance Validation

As a result of the assessment, the Compensation Committee concluded that our compensation structures are appropriate and no material risks were identified.
Compensation Committee Report
The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis set forth in this proxy statement with management. Based on this review and discussion, the Compensation Committee has recommended to the Board the inclusion of the Compensation Discussion and Analysis in this proxy statement, which is incorporated by reference in Avient’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Miscellaneous Provisions
Internet Availability of Proxy Materials
In accordance with rules and regulations adopted by the Securities and Exchange Commission, we may furnish proxy materials by providing internet access to those documents, instead of mailing a printed copy of our proxy materials to each shareholder. The Notice of Internet Availability of Proxy Materials contains instructions on how to access our proxy materials and vote online, or alternatively, request a paper copy of the proxy materials and a proxy card or voting instruction card.
Voting at the Meeting
Shareholders of record at the close of business on the Record Date, March 18, 2025, are entitled to vote at the Annual Meeting. On that date, a total of 91,532,654 common shares were outstanding. Each share is entitled to one vote.
The affirmative vote of a majority of the common shares represented and voting, in person (including virtually) or by proxy, at any meeting of shareholders at which a quorum is present is required for action by shareholders on any matter, unless the vote of a greater number of shares or voting by classes or series is required under Ohio law. Abstentions, withhold votes, and broker non-votes are tabulated in determining the votes present at a meeting for purposes of determining a quorum. Shareholders will not be entitled to dissenter’s rights with respect to any matter to be considered at the Annual Meeting.
Directors are elected by a plurality of the votes of shares present, in person (including virtually) or by proxy, and entitled to vote on the election of Directors at a meeting at which a quorum is present. A withhold vote or a broker non-vote with respect to a Director nominee will have no effect on the election of such Director nominee, as each withhold vote or broker non-vote would be one less vote in favor of a Director nominee whose election is subject to a plurality vote standard. Your broker or other nominee will not be able to vote your shares with respect to the election of Directors if you have not provided directions to your broker. We strongly encourage you to submit your proxy card and/or voting instruction card and exercise your right to vote as a shareholder. Holders of common shares have no cumulative voting rights. If any of the nominees listed in the “Proposal 1 – Election of Twelve Director Nominees to Our Board of Directors” section of this proxy statement becomes unable or declines to serve as a Director, each properly signed proxy card will be voted for another person recommended by the Board. However, we have no reason to believe that this will occur.
The affirmative vote of holders of at least a majority of the shares cast, in person (including virtually) or by proxy, is the applicable vote standard for Proposal 2. However, because the vote to approve Named Executive Officer compensation is advisory, there are technically no minimum vote requirements for this proposal. If there are a significant number of negative votes on the approval of Named Executive Officer compensation, we will seek to understand the concerns that influence the votes and expect to address them in making future decisions about our executive compensation programs. An abstention or broker non-vote will have no effect on this proposal as the abstention or broker non-vote will not be counted in determining the number of votes cast.
The affirmative vote of holders of at least a majority of the shares cast, in person (including virtually) or by proxy, is necessary for the ratification of the appointment of EY as our independent registered public accounting firm for the fiscal year ended December 31, 2025. Because the proposal to ratify the appointment of EY is considered “routine,” your broker or other nominee will be able to vote your shares with respect to this proposal without your instructions. An abstention will have no effect on this proposal as the abstention will not be counted in determining the number of votes cast.
PROXY STATEMENT 2025 | Annual Meeting of Shareholders 77

MISCELLANEOUS
We know of no other matters that will be presented at the Annual Meeting; however, if other matters do properly come before the Annual Meeting, the persons named in the proxy card will vote on these matters in accordance with their best judgment.
Revoking a Proxy
If you are a shareholder of record, you may revoke your proxy before it is voted by: (i) sending a written notice to our Secretary bearing a later date than the previously delivered proxy, stating that you revoke your proxy; (ii) mailing a completed and signed proxy card bearing a later date than the previously delivered proxy; (iii) voting by telephone or internet at a later date than the previously delivered proxy; or (iv) participating in the Annual Meeting and voting electronically online during the Annual Meeting.
Persons entitled to direct the vote of shares held by the Avient Retirement Savings Plan may revoke their proxy and voting instruction card before the trustee votes the shares held by it by giving notice in writing to the trustee. If you hold your shares through a bank, broker or other nominee, you must follow the instructions found on your voting instruction card, or contact your bank, broker or other nominee in order to revoke your previously delivered proxy, or participate in the Annual Meeting and vote electronically online during the Annual Meeting.
Shareholder Proposals
Any shareholder who wishes to submit a proposal in accordance with Rule 14a-8 promulgated under the Exchange Act to be considered for inclusion in next year’s proxy statement should send the proposal to us, addressed to the Secretary, so that it is received on or before November 27, 2025. We suggest that all proposals be sent by certified mail, return receipt requested.
Additionally, a shareholder may submit a proposal, including the nomination of Directors, for consideration at the 2026 Annual Meeting, but not for inclusion in next year’s proxy statement, if the shareholder gives timely written notice of such proposal in accordance with Regulation 8(c) or Regulation 12(b), as applicable, of our Regulations. In general, Regulation 8(c) and Regulation 12(b) provide that, to be timely, a shareholder’s notice must be delivered to or mailed and received by the Secretary at our principal executive offices not less than 90 nor more than 120 calendar days prior to the first anniversary of the date on which we first mailed our proxy materials for the preceding year’s Annual Meeting. If the date of the 2026 Annual Meeting is delayed by more than 60 calendar days after the anniversary of the Annual Meeting, then a shareholder’s notice must be delivered to our principal executive offices not later than the close of business on the later of the 90th calendar day prior to the 2026 Annual Meeting or the 10th calendar day following the day on which public announcement of the date of the 2026 Annual Meeting is first made.
Our proxy materials for the Annual Meeting will be released to shareholders beginning March 27, 2025. Ninety days prior to the first anniversary of this date will be December 27, 2025, and 120 days prior to the first anniversary of this date will be November 27, 2025. Our proxies for the 2026 Annual Meeting will confer discretionary authority to vote on any matter if we do not receive timely written notice of such matter in accordance with Regulation 8(c) or Regulation 12(b), as applicable. For business to be properly requested by a shareholder to be brought before the 2026 Annual Meeting, in addition to complying with the timeliness requirements set forth above, the shareholder must comply with all of the requirements of Regulation 8(c) or Regulation 12(b), as applicable, including, without limitation, with respect to the nomination of a director, a statement whether such shareholder intends to solicit the holders of shares representing at least 67% of the voting power of the Company's shares entitled to vote on the election of directors in support of director nominees other than Avient's nominees.

Proxy Solicitation
Avient is making this proxy solicitation and will bear the expense of preparing, printing and mailing this notice and proxy statement. In addition to requesting proxies by mail, our officers and regular employees may request proxies by telephone or in person. We will ask custodians, nominees, and fiduciaries to send proxy material to beneficial owners in order to obtain voting instructions. We will, upon request, reimburse them for their reasonable expenses for mailing the proxy material.
We are providing our Annual Report to Shareholders, including consolidated financial statements for the year ended December 31, 2024, to shareholders of record with this proxy statement.
We will furnish without charge to each person from whom a proxy is being solicited, upon written request of any such person, a copy of the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2024, as filed with the SEC, including the financial statements and schedules thereto. Requests for copies of such Annual Report on Form 10-K should be directed to: Avient Corporation, 33587 Walker Road, Avon Lake, Ohio 44012, Attention: Secretary.
Householding of Proxy Materials
The Securities and Exchange Commission has adopted rules that permit companies and intermediaries, such as brokers, to satisfy delivery requirements for proxy statements with respect to two or more shareholders sharing the same address and the same last name by delivering a single proxy statement addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for companies. Avient and some brokers household proxy materials, delivering a single proxy statement to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders.
Once shareholders have received notice from their broker or Avient that materials will be sent in the householding manner to the shareholder’s address, householding will continue until otherwise notified or until the shareholder revokes such consent. If, at any time, shareholders no longer wish to participate in householding and would prefer to receive separate proxy statements, they should notify their broker if their shares are held in a brokerage account, or Avient if they hold registered shares.
Avient will deliver promptly upon written or oral request a separate copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, proxy statement or Notice of Internet Availability of Proxy Materials, as applicable, to a shareholder at a shared address to which a single copy of the documents was delivered. To request the start or end of householding, shareholders should notify their broker or Avient. Any such written notice directed to Avient should be addressed to Equiniti Trust Company, LLC, 1110 Centre Pointe Curve, Suite 101, Mendota Heights, MN 55120 or oral notice may be given by calling +1-855-598-2615:
•to receive a separate copy of the Annual Report on Form 10-K for the fiscal year ended December 31, 2024, proxy statement or Notice of Internet Availability of Proxy Materials for the Annual Meeting;
•to receive separate copies of those materials for future meetings; or
•if the shareholder shares an address and wishes to request delivery of a single copy of proxy materials, rather than receiving multiple copies.

PROXY STATEMENT 2025 | Annual Meeting of Shareholders 79

Appendix A
Reconciliation of Non-GAAP Financial Measures (Unaudited)
(Dollars in millions, except per share data)
Senior management uses comparisons of diluted adjusted earnings per share (EPS) from continuing operations attributable to Avient shareholders, excluding special items, to assess performance and facilitate comparability of results. Senior management also uses adjusted operating income to assess performance and allocate resources because senior management believes that this measure is useful in understanding current profitability levels and how it may serve as a basis for future performance. In addition, adjusted operating income is a component of Avient’s annual employee incentive plans and is used in debt covenant computations.
Further, as a result of Avient's portfolio shift to an innovator of materials solutions, it has completed several acquisitions and divestitures, which have resulted in a significant amount of intangible asset amortization. Management excludes intangible asset amortization from adjusted EPS as it believes excluding acquired intangible asset amortization is a useful measure of current period earnings per share.
Senior management believes the measures described above are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. The presentation of these non-GAAP measures is not intended to be considered in isolation from, as a substitute for, or as superior to, the financial information prepared and presented in accordance with U.S. GAAP. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation from, or solely as alternatives to, financial measures prepared in accordance with GAAP. The presentation of these measures may be different from non-GAAP financial measures used by other companies.
A reconciliation of these measures to their most directly comparable GAAP measures is provided in the tables below.

The shares of common stock held will be voted as you specify on the reverse side. If no choice is specified, this proxy and voting instruction card will be voted FOR ALL nominees listed in Proposal 1 and FOR Proposals 2 and 3. By signing this proxy and voting instruction card, you revoke all prior proxies and appoint Amy M. Sanders, Jamie A. Beggs, and Kristen A.

IMPORTANT NOTICE TO PARTICIPANTS IN THE AVIENT RETIREMENT SAVINGS PLAN: As a participant under the Avient Retirement Savings Plan (the &quot;Plan&quot;), Fidelity Management Trust Company, as Trustee of the Plan, has been requested to forward you important information concerning your rights as a participant in the Plan. The number of common shares you are eligible to direct the Trustee to vote is based on your balance in the Plan (based on your balance in the Avient Stock Fund) on March 18, 2025, the record date for the determination of shareholders eligible to vote at the Annual Meeting of Shareholders to be held on May 14, 2025. We encourage you to exercise your rights under the Plan. Please review the enclosed documents carefully before deciding how to direct the Trustee. Because the common shares in the Plan are registered in the name of the Trustee, you will not be able to direct the common shares attributable to your interest in the Plan electronically online during the Annual Meeting of Shareholders. To give a proper direction, you must vote by returning this completed proxy and voting instruction card, signed and dated, in the enclosed envelope or by following telephone or internet voting procedures set forth in this proxy and voting instruction card. Directions must be received by May 12, 2025. If you give a proper direction, the Trustee will vote the common shares attributable to your interest in the Plan as you direct, unless otherwise required by law. If you do not give a proper direction, the Trustee will vote the common shares attributable to your interest in the same proportion as the proper directions that the Trustee does receive, unless otherwise required by law. Directions received after May 12, 2025 will not be counted for common shares held in the Plan. Your direction to the Trustee is confidential and will not be disclosed unless required by law. As a participant under the Avient Retirement Savings Plan, I hereby direct Fidelity Management Trust Company as Trustee of the Avient Retirement Savings Plan to vote (electronically online during the Annual Meeting of Shareholders or by proxy), as designated on the reverse side, the whole number of common shares of Avient Corporation that are held by the Trustee and attributable to my interest in the Plan on March 18, 2025, and also a proportionate number of shares as of such date to which no directions have been received, at the Annual Meeting of Shareholders to be held on May 14, 2025.
