Other than as described below, there have been no additional material changes to our risk factors as set forth in Part I, Item 1A of our Annual Report. You should carefully review and consider the information regarding certain factors which could materially affect our business, financial condition or future results set forth under the heading “Risk Factors” in our Annual Report.

Significant political, trade, regulatory developments, and other circumstances beyond our control, including as a result of recently announced tariffs, could have a material adverse effect on our financial condition or results of operations.

Changes in United States trade policy, including recently announced or potential future tariffs, could have a material adverse impact on our business, financial condition, and results of operations. The imposition of new tariffs or increases in existing tariffs on goods imported from or expected to be imported from countries where we or our suppliers operate could result in higher costs for materials or components essential to our operations. For example, in April 2025, the United States imposed broad tariffs on imports from virtually all countries, with particularly high tariffs on imports from China. Since this announcement, most tariffs for countries other than China have been suspended temporarily. In response to tariffs, some countries have implemented retaliatory tariffs on U.S. goods, while others seek to negotiate agreements regarding U.S.-imposed tariffs. Historically, tariffs have led to increased trade and political tensions and, to date, the outcome of the negotiations between the United States and the various countries is not yet clear. Political tensions as a result of trade policies could reduce trade volume, investment, technological exchange and other economic activities between major international economies, resulting in a material adverse effect on global economic conditions and the stability of global financial markets. Any changes in political, trade, regulatory, and economic conditions, including U.S. trade policies, could have a material adverse effect on our financial condition or results of operations.
