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 limitation, any supply chain and logistics issues; • Changes in 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 achieve strategic objectives and successfully integrate acquisitions, including Avient Protective Materials (APM); • An inability to raise or sustain prices for products or services; • 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 affecting our business beyond our control, including without limitation, changes in the general economy, changes in interest rates, changes in the rate of inflation and any recessionary conditions Use of Non-GAAP Measures This presentation includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. In addition, operating income before the effect of special items is a component of Avient’s annual and long-term employee incentive plans and is used in debt covenant computations. 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.

Efficacy of corrective actions is monitored and generally factored into trouble- shooting guides for situations where mistake proofing has not been effective. It is our policy to assess the competence of our employees, thereby determining training needs and then providing for the training of all personnel performing activities integral to the efficient and effective operation of our business. Training effectiveness is monitored periodically. 5.
