PROXY SUMMARY 4 PROXY STATEMENT 2022 | Annual Meeting of Shareholders OUR COMPANY CULTURE Avient Corporation was originally established as PolyOne Corporation in 2000. We consider diversity to include differences in race, gender, national origin, ethnicity, nationality, and sexual orientation, as well as differences in viewpoint, background, experience and skills. At that time, we viewed the targeted level of performance for each original measure as challenging to achieve.

Our work in sustainability originates from a core tenet of utilizing innovation to help our customers meet their commitments and to add value for our stakeholders—and ultimately—our planet. Avient Academy originated in 2003 to provide continual learning and professional development opportunities to associates around the globe. Avient has elected to utilize the reporting template provided by the Responsible Minerals Initiative (RMI) formerly Conflict-Free Sourcing Initiative, which facilitates the transfer of information through the supply chain regarding mineral countr y of origin as well as smelters and refiners being utilized.
