For the full year, adjusted EPS increased 58% to $3.05 driven by demand for sustainable solutions, healthcare applications and composites technologies.” In December, we completed our annual employee engagement survey and received our 3rd consecutive Great Place to Work® certification from the Great Place to Work Institute.” 3 2022 Outlook “As we discussed during our Investor Day in December, we have momentum in growing sustainable solutions, solving healthcare challenges and broadening advanced composite applications,” said Jamie A. 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 employs approximately 8,700 associates and is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

Next, the materials team formulated a grade that would offer enough heat resistance to be overmolded onto polypropylene, the underlying rigid material. Finally, the OnFlex-S HF grade was developed to bond sufficiently and be chemically compatible with polypropylene.

Thermoplastic composites include these base resins, but are combined with a structural filler such as glass, wood, carbon or polymer fibers to enhance strength, rigidity and structure. We also have what we believe is the broadest composite platform of solutions, which include a full range of products from long glass and carbon fiber technology to thermoset and thermoplastic composites.

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 long-term revenue 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.
