AVIENT CORP

We face a number of risks that could adversely affect our business, results of operations, financial position or cash flows. A discussion of our risk factors can be found in Item 1A, Risk factors, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Except for below, as of June 30, 2025, there have been no material changes to the risk factors that were previously disclosed.

Changes to foreign trade policy, including new or increased tariffs and changing import/export regulations, could adversely affect our operating results, and the impacts could be material.

Changes in foreign trade policy, regulatory or economic conditions or in laws governing international trade could materially adversely affect our business. The U.S. has instituted certain changes, and may propose additional changes, in trade policies that include the negotiation or termination of trade agreements, the imposition of higher tariffs on goods exported from the U.S. or imported into the U.S., and other government regulations affecting trade between the U.S. and other countries (such as Canada, Mexico, China, and the European Union) where we conduct our business. Global trade disruption or significant introduction of trade barriers, together with any future downturns in the global economy, could further materially and adversely affect our financial performance.

As a result of policy changes and government proposals, there may be greater restrictions and economic disincentives on international trade. The new tariffs and other changes in U.S. trade policy have triggered retaliatory actions by affected countries, and foreign governments have instituted or are considering imposing tariffs and trade sanctions. Such changes have the potential to adversely impact the global economy, our industry and the global demand for our products, and as a result, could have a negative impact on our business, financial condition and results of operations.
