Just a few months ago, we completed the acquisition of the Clariant Masterbatch business, the largest acquisition in the 20-year history of our company. It’s in this spirit that we joined legacy PolyOne and the Clariant Masterbatch business, two complementary businesses, and formed a new one that we’ve named Avient. We will deliver for our stakeholders through multiple value creation levers—many of which are unique to Avient: o Demand for sustainable solutions, healthcare, and composites, together with Clariant Masterbatch revenue synergies, that will drive 2021 revenue growth of 8% and long-term growth in excess of GDP o Clariant Masterbatch cost synergy capture will result in significant near-term benefit In addition, we remain committed to increasing annual dividends in line with earnings growth and opportunistically buying back shares, all while remaining modestly levered.
