Underlying organic sales growth plus the addition of Magenta's fiber colorant business and Kraton's TPE business was more than offset by lower year-over-year selling prices in Distribution, PP&S, and Designed Structures and Solutions (DSS), due to lower hydro-carbon based raw material costs.

Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility

Notable new product advancements include ColorMatrix™ liquid fiber colorants that improve production efficiency and speed to market for textile applications, WithStand™ antimicrobial additives that help prevent surface bacteria, and Gravi-Tech™ high-density polymers that elevate the texture, feel and aesthetics of luxury packaging.

If achievement with respect to any performance measure falls between the threshold and target, or between the target and maximum, earned award amounts for that particular performance measure will be interpolated on a straight-line mathematical basis. If final performance for any measure falls between the threshold and target or between target and maximum, earned award amounts for that measure will be interpolated on a straight-line mathematical basis. If final performance falls between the threshold and target or between target and maximum for any performance period, then the earned award amount for that performance period will be interpolated on a straight-line mathematical basis.

Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility

Examples include: • Dyneema®, the world's strongest fiber™, enables unmatched levels of performance and protection for end-use applications, including ballistic personal protection, marine and sustainable infrastructure and outdoor sports; • Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy; PROXY SUMMARY 6 PROXY STATEMENT 2024 | Annual Meeting of Shareholders • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint; • Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resources conservation and fiber optic / 5G network accessibility. 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. 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 Fiscal Years.

Patterson’s Summary Compensation Table compensation is in line with our performance over this period of time. If final performance for any measure fallff s between the threshold and target or between target and maximum, earned award amounts forff that measure will be interpolated on a straight-line mathematical basis. If final performance falls between the threshold and target or between target and maximum for any perforff mance period, then the earned award amount for that performance period will be interpolated on a straight-line mathematical basis.

Some of the more common conflicts of interest may arise when you: • Take part in activities that compete with, or appear to compete with, our company’s interests • Receive any personal or financial benefit from, have a financial interest in, work for, or provide services for a company that does or is seeking to do business with us or a competitor • Let your business decisions be influenced, or appear to be influenced, by personal or family interests or friendships— for example, where businesses you or a member of your family own or operate seek to do business with Avient • Do outside work (including board service) that negatively impacts your job performance or interferes with your responsibilities to Avient • Use company property, information or resources for your personal benefit or the benefit of others • Hire, supervise or have a direct or indirect line of reporting to a family member, including in-laws, or someone with whom you have a romantic relationship • Have a business, or a member of your family has a business, that you or they own or operate that seeks to do business with Avient • Have a family member that works for a customer or supplier with which you or an associate who reports to you has business dealings Disclosure Process A conflict of interest is not always clear-cut and easy to recognize, and it can innocently arise.

We have defined our Sustainability Portfolio in the eight ways we help our customers meet their innovation and sustainability goals: The benefits of these solutions include: • Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint • Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility As the world begins to shift from operating in a linear economy to a circular economy, Avient is proud to be a part of the solution. 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.
