In 2023, we had a recordable incident rate of 0.58 per 100 full-time workers per year, compared to the Plastics and Rubber Products Manufacturing industry (NAICS Code 326) average of 3.40 in 2022. We believe that we are in material compliance with all applicable requirements. 6 AVIENT CORPORATION We are strongly committed to safety as evidenced by our low injury incidence rate of 0.58 per 100 full-time workers per year in 2023 and 0.51 in 2022. Forfeitures were estimated at 3% per year based on our historical experience.

LSR and other engineering elastomers typically cost more per pound than standard elastomers. However, price per pound is just one aspect of the overall cost. Use this simple calculation: Specific Gravity X Price Per Pound = Pound/Volume Cost

The non-GAAP financial measures include: Adjusted Earnings Per Share, Adjusterd Free Cash Flow, Adjusted EBITDA and Adjusted EBITDA margins. Avient does not provide reconciliations of forward-looking non-GAAP financial measures, such as outlook for Adjusted EBITDA and Adjusted Earnings Per Share, 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. Management excludes intangible asset amortization from adjusted EPS as it believes excluding acquired intangible asset amortization is a useful measure of current period earnings per share.

This 16th edition of the annual color forecasting guide for the plastics industry marks its debut within Avient, which was formed this year from legacy businesses PolyOne and Clariant Masterbatch. As in years past, ColorForward 2022 presents stories associated with four societal trends that are expected to influence consumers consciously or unconsciously over the next few years. This year, ColorForward 2022 trend watchers expect the effects of the COVID-19 pandemic to linger for some time, even if vaccines and treatments allow the world to return to some semblance of ‘normal.’
