With the Clariant Color business acquisition and divestment of the PP&S business, our exposure is now concentrated in less-cyclical and high-growth markets, with increased geographic diversification and a more specialized portfolio that can significantly expand EBITDA margins. 24 Avient reflects 2021 estimated EBITDA of $580M OUR VALUATION VERSUS PEERS Avient Specialty Other 11.0 18.3 16.3 15.4 14.5 11.6 11.1 36.2 28.0 24.9 13.0 11.5 11.3 10.0 9.2 8.8 7.7 6.7 en t SUMMARY: WHY INVEST IN AVIENT?
