Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: • The time required to consummate the acquisition of the Dyneema business, the satisfaction or waiver of conditions in the purchase agreement, the ability to obtain required regulatory or other third-party approvals and consents and otherwise consummate the proposed acquisition of the Dyneema business; • Our ability to achieve the strategic and other objectives relating to the proposed acquisition of the Dyneema business and possible sale of the Distribution business; • 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; • 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; • Our ability to pay regular quarterly cash dividends and the amounts and timing of any future dividends; • Information systems failures and cyberattacks; • 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, 2021 under Item 1A, “Risk Factors.” Avient 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 Avient is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort.

Commercially available in North America, the new specialty Versaflex grades are translucent and offer excellent colorability.

Available globally, ECCOH low smoke and fume, non-halogen (LSFOH) flame-retardant materials are well suited for settings where smoke mitigation is of particular concern.

Available in customized chemistries, these esters can accelerate manufacturers’ speed-to-market, especially at the lower volumes typical for emerging and specialty oils, fluids, and greases.

Our custom color and additive concentrates are available in solid and liquid form.
