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; • disruptions or inefficiencies in our supply chain, logistics, or operations; • changes in laws and regulations in jurisdictions where we conduct business, including with respect to plastics and climate change; • fluctuations in raw material prices, quality and supply, and in energy prices and supply; • demand for our products and services; • 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; • our ability to service our indebtedness and restrictions on our current and future operations due to our indebtedness; • 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; • 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, geopolitical conflicts, tariffs, and any recessionary conditions; and • other factors described in our Annual Report on Form 10-K under Item 1A, “Risk Factors.” Senior management believes these measures 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.

Special items include charges related to specific strategic initiatives or financial restructuring such as: consolidation of operations; debt extinguishment costs; costs incurred directly in relation to acquisitions or divestitures; employee separation costs resulting from personnel reduction programs, plant realignment costs, executive separation agreements; asset impairments; settlement gains or losses and mark-to-market adjustments associated with actuarial gains and losses on pension and other post-retirement benefit plans; environmental remediation costs, fines, penalties and related insurance recoveries related to facilities no longer owned or closed in prior years; gains and losses on the divestiture of operating businesses, joint ventures and equity investments; gains and losses on facility or property sales or disposals; results of litigation, fines or penalties, where such litigation (or action relating to the fines or penalties) arose prior to the commencement of the performance period; one-time, non-recurring items; and the effect of changes in accounting principles or other such laws or provisions affecting reported results.
