During processing, polymers often degrade due to oxygen and heat exposure which causes such things as discoloration, gels, and black spots. It is a specialized antioxidant additive that stabilizes polyolefins during processing—preventing the typical defects like discoloration, gels, and black spots—during initial, and future conversion steps and recycling loops. Sustainability Spotlight Recycle Solutions KEY CHARACTERISTICS • Designed for polyolefin recycling and to enhance circularity • Protects polyolefins against degradation caused by oxygen and heat during processing • Provides improved stability against oxygen degradation and discoloration • Stabilizes the polymer to reduce creation of new gels and black spots • Excellent performance at low dosage levels MARKETS & APPLICATIONS • Recycled polyolefins • Packaging, consumer & others • High-value polyolefin applications with recycled material content • Virgin polymers which will be recycled after the use phase Copyright © 2022, Avient Corporation.

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. Such is the case with the Clariant Masterbatch acquisition, where strong free cash flow will allow us to de-lever quickly. 19 AVIENT IS MODESTLY LEVERED 1.

Finding suppliers of fluoropolymer color and additive masterbatches able to meet its standards has not always been easy. That inconsistency led to masterbatches that included lumps and lot-to-lot color differences. With RoHS and REACH documentation on all masterbatch orders, international customers were an option once again.

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.
