When showing constant dollar figures on GAAP and non-GAAP financial measures, the foreign exchange impact is calculated by using current foreign exchange rates and applying them to the prior period results. Avient does not provide reconciliations of forward-looking non-GAAP financial measures, such as outlook for Adjusted EBITDA, Adjusted Earnings Per Share 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. Examples include: • Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint • Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility Avient is a certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste.

Solar power is one of the most powerful alternative energy sources. Office of Energy Efficiency & Renewable Energy, the amount of sunlight that strikes the earth’s surface in an hour and a half is enough to handle the entire world’s energy consumption for a full year. In some cases, one float generates enough energy to power 375 homes for a year*.
