They are based on management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: • Disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; • The effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; • The current and potential future impact of the COVID-19 pandemic on our business, results of operations, financial position or cash flows, including without any limitation, any supply chain and logistics issues; • Changes in polymer consumption growth rates and laws and regulations regarding plastics in jurisdictions where we conduct business; • Fluctuations in raw material prices, quality and supply, and in energy prices and supply; • Production outages or material costs associated with scheduled or unscheduled maintenance programs; • Unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; • Our ability to pay regular quarterly cash dividends and the amounts and timing of any future dividends; • Information systems failures and cyberattacks; • Amounts for cash and non-cash charges related to restructuring plans that may differ from original estimates, including because of timing changes associated with the underlying actions; • Any material adverse changes in the equity and assets of Koninklijke DSM N.V.’s protective materials business (“the Dyneema Business”); • Our ability to achieve the strategic and other objectives relating to the acquisition of the Dyneema Business and the possible sale of the Distribution business segment; and • Other factors described in our Annual Report on Form 10-K for the year ended December 31, 2021 and our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2022 under Item 1A, “Risk Factors.” D I S T R IBU T I O N) 18 END-MARKET FOCUS FOR NEW INNOVATION Semiconductors Robotics Healthcare Interconnected disruptive markets with massive innovation needs 19 APPENDIX Performance Additives 15% Pigments 13% TiO2 11% Dyestuffs 3%Polyethylene 12% Nylon 6% Polypropylene 5% Other Raw Materials 30% Styrenic Block Copolymer 5% ~40% hydrocarbon based (Grey shaded materials are hydrocarbon based, includes portion of “Other Raw Materials”) Non-hydrocarbon based materials 22 • Significant raw material price inflation and tight inventory continued in Q2 2022, although at a slightly lesser rate compared to the prior quarter o For Q2 2022, the average cost of key hydrocarbon based materials was up 15%, roughly the same as the average cost of non- hydrocarbon based materials. • Continued supply chain challenges persisted during Q2 related to raw material spot purchases, freight constraints and productivity loss as a result of these shortages.

These materials must be able to withstand the effects of hydrogen transfer without contaminating the energy source or harming the pipe in order to keep the energy system safe. However, the company needed a new material for this applicator that could meet the necessary strength, flexibility, and adhesive properties required for it to be easily deployed in the field. The reinforcement material increased breaking efficiency, resistance to long-term creep, elevated temperatures, and cyclical strain- based fatigue.

Pro Forma Financial Information The Company acquired Avient Protective Materials (“Dyneema”) on September 1, 2022 (the “Acquisition Date”) and sold the Distribution segment on November 1, 2022. 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.
