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.
