Arista Networks Inc.: 10-K Risk Factor Changes

Our products are primarily manufactured in Malaysia, Vietnam, and Mexico, and we also procure a limited number of products originating from China, Taiwan, Thailand and the Philippines. In addition, our contract manufacturing partners procure some components from China for use in the manufacturing of our products. Because our products are primarily manufactured internationally, the import of our products into the U.S. may be affected by applicable tariff policies. Over the last decade, and especially under the current administration, the U.S. government has enacted various new and increased tariffs affecting the import of various items from various countries. For example, since 2018, the U.S. government has enacted various tariffs on products from China under Section 301 trade authorities, including on communications equipment products and components manufactured and imported from China. Since February 2025, the U.S. has also imposed additional country-specific tariffs on most trading partners, including China, as well as additional commodity-specific tariffs on certain imported items, in both instances pursuant to executive orders issued under various trade authorities, including the International Emergency Economic Powers Act and Section 232 of the Trade Expansion Act of 1962. In response to these and other U.S. measures, China, Mexico and other countries have taken or threatened to take a range of retaliatory measures. These include the imposition of retaliatory tariffs on certain U.S.-origin goods; the implementation of new export controls by China on various critical minerals, including rare earths metals; the scheduling of further retaliatory tariff measures; and other actions that may affect us directly or indirectly. The situation regarding these tariffs and trade policies has been and continues to be fluid, leading to significant uncertainty about the future relationship between the U.S., and other countries, with respect to tariffs and trade policies. The U.S., China, Malaysia, Vietnam, Mexico, Taiwan, Thailand, the Philippines and other governments may place additional tariffs and trade barriers on communication equipment products, our products and services, our inputs, or other items, which could result in higher costs to us and negatively affect our gross margins. An increase in trade-related costs associated with these tariff actions may affect our cost of production, impair the profitability of our international production, affect our ability to procure certain items, strain our suppliers’ ability to provide 15 15 15 inputs necessary to produce certain items, and otherwise affect our manufacturing partners’ ability to provide our products at previously contracted prices. We also may not be able to pass on the full burden of the increase in trade-related costs to our partners and/or customers which could impact our profitability and/or our competitiveness. We are adjusting our supply chain and manufacturing practices to minimize the impact of the tariffs and any impact on the supply chain of components sourced from affected countries, but our efforts may not be successful. In addition, there can be no assurance that we will not experience a disruption in our business related to these or other changes in trade practices, and the process of changing suppliers in order to mitigate any such tariff costs could be complicated, time-consuming, and costly. Tariffs may also cause customers to delay or to request an expedition for their orders as they evaluate where to take delivery of our products in connection with their efforts to mitigate their own tariff exposure. Such delays or expeditions may create forecasting difficulties for us and increase the risk that orders might be canceled or might never be placed. Current or future tariffs may also negatively impact our customers' sales, thereby causing an indirect negative impact on our own sales. Even in the absence of further tariffs, the related uncertainty and the market's fear of escalating trade tensions and related macroeconomic effects might cause our distributors and customers to place fewer orders for our products, which could have a material adverse effect on our business, liquidity, financial condition, and/or results of operations.
