Webcast Details Avient will provide additional details on its 2024 third quarter results and 2024 full-year outlook during its webcast scheduled for 8:00 a.m. The Company does not provide reconciliations of forward-looking non-GAAP financial measures, such as adjusted EPS and adjusted EBITDA, to the most comparable GAAP financial measures on a forward-looking basis because the Company is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. About Avient Avient Corporation (NYSE: AVNT) provides specialized and sustainable materials solutions that transform customer challenges into opportunities, bringing new products to life for a better world.

Avient does not provide reconciliations of forward-looking non-GAAP financial measures, such as outlook for Adjusted EBITDA, Adjusted Earnings Per Share, Adjusted Operating Income and Free Cash Flow, 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. To provide comparable results, the company references “pro forma” financial metrics, which include the business results of Avient Protective Materials for periods prior to the Acquisition Date, as if the transaction occurred on January 1, 2021 and reflect Distribution as a discontinued operation. Management believes this provides comparability of the performance of the combined businesses.

Unlimited lengths and a continuous manufacturing process also provide significant cost savings over traditional composite panel manufacturing techniques. Some of the information arises from laboratory work with small-scale equipment which may not provide a reliable indication of performance or properties obtained or obtainable on larger-scale equipment.

Available in a wide range of customizable colors, these impact-modified nylon formulations eliminate secondary painting processes—unlike traditional materials such as painted plastics or metals—providing the added manufacturing and sustainability benefits of reducing energy use and removing VOC emissions. Some of the information arises from laboratory work with small-scale equipment which may not provide a reliable indication of performance or properties obtained or obtainable on larger-scale equipment.

Reliable coloration to RAL 7011 and RAL 7035 colors was also required, something hard to provide when using post-consumer recycled (PCR) content, as performance can be more unstable than prime material. The new grades were formulated to provide a functional replacement for the previous used prime materials while incorporating 50% recycled ocean- bound plastic content.
