Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: • The impact of the COVID-19 pandemic has on our business, results from operations, financial condition and liquidity; • Our ability to achieve the strategic and other objectives relating to the acquisition of Clariant’s Masterbatch business, including any expected synergies; • 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; • Changes in polymer consumption growth rates and laws and regulations regarding the disposal of plastic in jurisdictions where we conduct business; • Changes in global industry capacity or in the rate at which anticipated changes in industry capacity come online; • 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 raise or sustain prices for products or services; • An ability to achieve or delays in achieving or achievement of less than the anticipated financial benefit from initiatives related to acquisitions and integration, working capital reductions, cost reductions, and employee productivity goals; • Information systems failures and cyber attacks; and • Other factors affecting our business beyond our control, including, without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation. Examples include: • Barrier technologies that preserve the shelf-life and quality of food, beverages, medicine and other perishable goods through high- performance materials that require less plastic • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation • Breakthrough technologies that minimize wastewater, improve the recyclability of materials and advance a circular economy • Composite solutions to support accelerated growth of 5G / fiber-optic infrastructure investment as the world demands greater and faster connectivity Avient employs approximately 8,400 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste. Ultimately, it’s about delivery – on time, efficient, and to the exact quality specifications that our customers demand.

We are putting data to work to boost efficiency, productivity, quality and safety across industrial, manufacturing, infrastructure, public sector, and mobility applications.

Furthermore, designers, quality, and regulatory specialists face new compliance challenges as regulations such as the In Vitro Diagnostics Regulation (IVDR) EU2017/746 are tightened and impact of reclassifications come into force.
