Selling and administrative expense decreased $72.3 million for the six months ended June 30, 2026, primarily driven by the Company's decision to cease development of the cloud-based enterprise resource planning system, S/4HANA, in 2025, which resulted in an impairment charge of $71.6 million and additional charges of $14.7 million for unpaid contractual obligations for hosting fees, which more than offset higher employer costs. Interest expense, net Interest expense, net decreased $2.4 million and $7.3 million for the three and six months ended June 30, 2026, respectively, primarily driven by the benefit of reduced interest rates resulting from refinancing activity during 2025, in addition to prepayments on Avient's senior secured term loan totaling $150.0 million during 2025. Income taxes During the three months ended June 30, 2026, the Company’s effective tax rate was 26.3% compared to 24.5% in the three months ended June 30, 2025, while the six month period ended June 30, 2026 was 24.7% compared to 24.2% for the six month period ended June 30, 2025. The higher effective tax rate in 2026 is primarily driven by an increase in withholding taxes and higher unfavorable U.S. permanent items. Refer to Note 6, Income Taxes, for further details. SEGMENT INFORMATION Avient has two reportable segments: (1) Color, Additives and Inks; and (2) Specialty Engineered Materials. Operating income is the primary segment performance measure that is reported to our chief operating decision maker (CODM), which is the Company's chief executive officer. Our CODM utilizes this measure as an input to determine appropriate resource allocations to our segments in the annual planning process and to periodically assess segment performance, primarily by evaluating actual results in comparison to the annual operating plan and forecast. Operating income at the segment level does not include corporate general and administrative expenses that are not allocated to segments, restructuring charges, share-based compensation costs, environmental remediation costs and associated recoveries, asset impairments, acquisition-related charges, mark-to-market adjustments on pension and other post-retirement obligations, and certain other items that are not included in the measure of segment profit or loss that is reported to and reviewed by our CODM. These costs are included in Corporate.

Liquidity and Capital Resources Our objective is to finance our business through operating cash flow and an appropriate mix of debt and equity. By laddering the maturity structure, we avoid concentrations of debt maturities, reducing liquidity risk. We may from time to time seek to retire or purchase our outstanding debt with cash and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. We may also seek to repurchase our outstanding common shares. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved have been and may continue to be material. 17 AVIENT CORPORATION The following table summarizes our liquidity as of June 30, 2026 and December 31, 2025: (In millions) As of June 30, 2026 As of December 31, 2025 Cash and cash equivalents $ 425.6 $ 510.5 Revolving credit availability 490.5 490.3 Liquidity $ 916.1 $ 1,000.8 As of June 30, 2026, approximately 78% of the Company’s cash and cash equivalents resided outside the United States. Expected sources of cash needed to satisfy cash requirements for the remainder of 2026 include our cash on hand, cash from operations and available liquidity under our revolving credit facility, if necessary. We believe that these sources will also provide sufficient liquidity to satisfy our expected uses of cash for at least the next twelve months and the foreseeable future thereafter. Expected uses of cash for the remainder of 2026 include interest payments, cash taxes, dividend payments, debt repayments, environmental remediation payments, restructuring payments and capital expenditures. Cash Flows The following describes the significant components of cash flows from operating, investing and financing activities for the six months ended June 30, 2026 and 2025. Operating Activities — Net cash provided by operating activities decreased $2.4 million during the six months ended June 30, 2026 compared to the six months ended June 30, 2025, primarily driven by higher earnings offset by an investment in working capital and higher restructuring payments. Investing Activities — Net cash used in investing activities during the six months ended June 30, 2026 and 2025 of $41.3 million and $39.5 million, respectively, reflects the impact of capital expenditures. Financing Activities — Net cash used in financing activities for the six months ended June 30, 2026 and 2025 of $103.0 million and $106.4 million, respectively, primarily reflects dividend payments and prepayments on Avient's senior secured term loan. 18 AVIENT CORPORATION Debt As of June 30, 2026, aggregate maturities of the principal amount of debt for the current year, next four years and thereafter, are as follows: (In millions) 2026 $ 0.2 2027 0.4 2028 0.4 2029 521.1 2030 725.5 Thereafter 651.0 Aggregate maturities $ 1,898.6 On March 12, 2025, the Company refinanced its senior secured term loan by amending the credit agreement governing such term loan (the Term Loan Amendment). The Term Loan Amendment reduced the interest rate per annum by 25 basis points, which now is either (i) Adjusted Term SOFR (as defined in the Term Loan Amendment) plus 1.75%, or (ii) a Base Rate (as defined in the Term Loan Amendment) plus 0.75%. The maturity date and other terms and conditions are substantially the same as the terms and conditions under the credit agreement immediately prior to the Term Loan Amendment. On June 12, 2025, the Company entered into a revolving credit agreement (the Revolving Credit Agreement) with various financial institutions as lenders, and JPMorgan Chase Bank, N.A., as administrative agent, which replaced our previous credit agreement. The Revolving Credit Agreement provides for a senior secured revolving credit facility of up to $500.0 million, which may be increased by up to $250.0 million, subject to certain conditions. Loans under the Revolving Credit Agreement will mature on June 12, 2030. The Revolving Credit Agreement contains representations and warranties, affirmative covenants, negative covenants and events of default that are substantially similar to those contained in the Company's existing term loan credit agreement. In 2025, the Company made voluntary prepayments of $150.0 million on its senior secured term loan, which were applied to the principal installments in direct order of maturity. These prepayments were made using cash on hand and without penalty or premium. In June 2026, the Company made voluntary a prepayment of $50.0 million on its senior secured term loan, which was applied to the principal installments in direct order of maturity. This prepayment was made using cash on hand and without penalty or premium. As of June 30, 2026, we were in compliance with all financial and restrictive covenants pertaining to our debt. For additional information regarding our debt, please see Note 7, Financing Arrangements, to the accompanying condensed consolidated financial statements. Derivatives and Hedging We are exposed to market risks, such as changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures we may enter into various derivative transactions. For additional information regarding our derivative instruments, please see Note 8, Derivatives and Hedging, to the accompanying condensed consolidated financial statements. Material Cash Requirements We have future obligations under various contracts relating to debt and interest payments, operating leases, pension and post-retirement benefit plans, purchase obligations, restructuring payments and environmental remediation obligations. During the six months ended June 30, 2026, there were no material changes to these obligations as reported in our Annual Report on Form 10-K for the year ended December 31, 2025. 19 AVIENT CORPORATION CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS In this Quarterly Report on Form 10-Q, statements that are not reported financial results or other historical information are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.
