For more information, visit https://www.avient.com. 4 Forward-looking Statements In this press release, 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.

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; • The current and potential future impact of the COVID-19 pandemic on our business, results of operations, financial position or cash flows, including without any limitation, any supply chain and logistics issues; • Our ability to achieve the strategic and other objectives relating to the acquisition of Clariant’s Color business, including any expected synergies; • Changes in polymer consumption growth rates and laws and regulations regarding plastics in jurisdictions where we conduct business; • Fluctuations in raw material prices, quality and supply, and in energy prices and supply; • 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; • An inability to achieve the anticipated financial benefit from initiatives related to acquisition and integration working capital reductions, cost reductions and employee productivity goals; • 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 consummate and successfully integrate acquisitions; • 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; and • Other factors described in our Annual Report on Form 10-K for the year ended December 31, 2020 under Item 1A, “Risk Factors.” The Company does not provide reconciliations of forward-looking non-GAAP financial measures, such as outlook for Adjusted EBITDA, Adjusted Earnings Per Share, Adjusted Operating Income and Free Cash Flow, to the most comparable GAAP financial measures on a forward-looking basis because the Company is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This innovation drives performance and is reflective of consistent, strategic investments in technology and people Clariant Color business acquired July 1, 2020 10 30 40 14 25 22 35 19 18 41 Current Additional share needed to reach 2025 target BRAND OWNERS COMMITTED TO INCREASING USE OF RECYCLED MATERIALS 8 Brand Owner 1 Brand Owner 3 Brand Owner 2 Brand Owner 7 Brand Owner 4 Brand Owner 10 Brand Owner 6 Brand Owner 11 Brand Owner 5 Brand Owner 8 Brand Owner 9 Brand Owner 12 Brand Owner 13 Percent recycled plastic used: (examples and not exhaustive) (1) Latest year reported.
