Changes in tariffs and international trade policies affecting imports and exports may have a material adverse effect on our business operations and financial performance.

Current report

The U.S. has recently proposed the implementation of a range of new tariffs and significant increases to existing tariffs. In response to such tariffs announced by the U.S., other countries have imposed or are considering imposing new or increased tariffs on certain exports from the U.S. There is currently significant uncertainty about the future relationship between the U.S. and other countries with respect to tariffs, trade policies, taxes and other related government regulations, and we cannot predict whether, and to what extent, current tariffs will continue or trade policies will change in the future. Such uncertainties and risks may negatively affect our ability to enter into new business transactions with partners, vendors and customers because of the lack of clarity on the economic benefits of such transactions. Significant increase in U.S. tariffs may increase the costs of materials, goods and components that we purchase from suppliers from other countries for the manufacturing and distribution of our products, which may adversely affect our financial performance. Also, we may not be able to mitigate the impact of tariffs by identifying and securing alternative sources in the U.S. for similar materials, goods and components at comparable qualities or more favorable prices. In addition, retaliatory tariffs from other countries could have a significant negative impact on our business overseas that rely on imports of goods and products from the U.S. Furthermore, tariffs, or the threat of tariffs or increased tariffs, could have a significant negative impact on our business relationships with customers, suppliers and partners in Asia, including China, Hong Kong, Taiwan, Korea and Japan. Any significant changes in trade policies and tariffs may also affect the business operations of our customers, suppliers and partners, which may cause them to take actions or make decisions that adversely affect our business operations and results of operations.
