The new U.S. presidential administration has proposed taken multiple actions in 2025 to significantly increase tariffs on foreign imports into the United States, including imports from countries to which we export our products, such as Canada and China. For example, on February 1, 2025, the United States imposed tariffs on imports from Canada, Mexico and China, and on April 2, 2025, the United States announced a universal baseline tariff of 10% on almost all imports, plus additional country-specific tariffs for select trading partners, including China. The rates and effective dates of these tariffs have been adjusted on several occasions since the initial announcements, and certain of these tariffs are subject to legal and other challenges, the outcome of which could further change tariff rates and effective dates.

Several countries, including Canada and China, have imposed retaliatory tariffs, and the imposition of U.S. and foreign tariff regimes is fluid and changing. We could therefore experience reduced revenues and margins in our businesses that are adversely affected by international trade policy or disputes, including the terms of any settlement of such disputes. To the extent such trade policies increase prices, they could also reduce the overall demand for our products in affected markets. Likewise, U.S.-imposed tariffs on imports could also increase our costs for products and raw materials that we use in our operations, and we operations. We may not be able to pass on those cost increases to our customers. These changes could therefore have a material adverse effect on our business, financial results customers, and financial condition, including facility closures or impairments of assets. We cannot predict future U.S. or foreign trade policy or the terms and conditions of any resolutions or settlements of international trade disputes and their effects on our business. if
