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. For the same reasons, Avient is unable to address the probable significance of the unavailable information. 2 3 Q3 2024 HIGHLIGHTS • 8.5% organic sales growth driven by broad-based growth across all regions and most end markets in both CAI and SEM segments • Growth stemmed from gaining share, winning new product specifications and restocking in certain end markets • Both segments expanded YoY EBITDA margins by 40 bps each • Adjusted EPS of $0.65, an increase of 14% vs the prior year • Successfully refinanced $650M outstanding senior notes due 2025; extending maturity to 2031 • Increased dividend 5% to $1.08 on an annualized basis; 14th consecutive increase Adj. Senior management believes the measures described above are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude.

Based on expertise in reducing weight and improving portability of mast structures and antennas for the military, Rolatube engineers realized the legs of the tripod could be designed to roll into a compact and portable coil, eliminating the complexity and added weight of telescopic hardware. The thermoplastic polymer base resin used also enables recyclability to support the company’s sustainability goals.

They wanted to transition from metal to a polymer-based, two-component handle that would deliver: • scratch and chemical resistance • excellent mechanical properties • a grippy, soft-touch feel To support the transition, Victorinox sought our help based on its expertise in polymer science and ability to support product development and efficient manufacturing of the new two-component handles.

These materials also offer a sustainability benefit through a reduced carbon footprint because PK base resin production emits up to 61 percent less carbon dioxide (CO2) than nylon, helping to improve sustainability over the end-product lifecycle.
