In addition to the other information set forth in this Quarterly Report, you should carefully consider the risk factors and other cautionary statements described in Part I, Item 1A. “Risk Factors” in our Annual Report, which could materially affect our business, financial condition or future results. Except for the risk factor set forth below, there have been no material changes to the risk factors described in our Annual Report.

Recent tariffs and other trade actions taken by the U.S. and other countries where we do business have increased, and may continue to increase, our import and export costs, potentially requiring us to increase our prices or find alternative suppliers which, in turn, may harm our relationships with customers, reduce demand for our products and decrease our profitability.

Beginning in the first quarter of 2025, the U.S. government has imposed a series of tariffs on products imported into the U.S. In response to these tariffs and other changes in U.S. trade policy, several countries, including China, have threatened or imposed retaliatory tariffs on U.S. exports. The continuing imposition of tariffs by the U.S. and others may also give rise to further escalations of protectionist and retaliatory trade measures.

These tariffs and other trade measures could have a material adverse effect on our business, results of operations, or financial condition. Our business and operating results are heavily dependent on international trade. We import raw materials and finished goods into the U.S. and we export products from the U.S. to our customers throughout the world, including those in China. Because of the recent tariffs and other trade restrictions, we have experienced increased and additional costs with respect to our import and export of such materials, finished goods, and products, and we may continue to experience these costs. In turn, we may be required to increase the prices of our products, which may reduce demand and harm our relationships with our customers. If we do not, or are unable to, increase prices without reducing demand, we may experience reduced profitability. Furthermore, retaliatory tariffs imposed by countries where we have significant sales, like China, could cause our customers to source products from local and non-U.S. competitors, which could further reduce demand for, and the overall competitiveness of, our products and decrease our market share. Additionally, we may be required to source our materials from alternative suppliers which could significantly increase our costs, lead to significant delays, and result in reliability or quality issues, all of which could harm our reputation and decrease demand for our products. The extent and duration of the tariffs and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our products in affected markets.
