Because we sell our products worldwide, our businesses are subject to risks associated with doing business internationally. Our sales originating outside the United States represented the majority of our total revenue in fiscal year 2025. We anticipate that sales from international operations will continue to represent a substantial portion of our total revenue. In addition, many of our manufacturing facilities, employees and suppliers are located outside the United States. Accordingly, our future results of operations could be harmed by a variety of factors, including:
- changes in actual, or from projected, foreign currency exchange rates,- global health crises of unknown duration,- wars, conflicts, or other changes in a country's or region's political or economic conditions, particularly in developing or emerging markets,- longer payment cycles of foreign customers and timing of collections in foreign jurisdictions,- trade protection measures including embargoes, sanctions and tariffs, as well as the sanctions and other restrictions implemented by the United States and other governments on the Russian Federation and related parties in connection with the conflict in Ukraine,- import or export licensing requirements and the associated potential for delays or restrictions in the shipment of our products or the receipt of products from our suppliers,- policies in foreign countries benefiting domestic manufacturers or other policies detrimental to companies headquartered in the United States,- differing tax laws and changes in those laws, or changes in the countries in which we are subject to tax,- adverse income tax audit settlements or loss of previously negotiated tax incentives,- differing business practices associated with foreign operations,- difficulty in transferring cash between international operations and the United States,- difficulty in staffing and managing widespread operations,- differing labor laws and changes in those laws,- differing protection of intellectual property and changes in that protection,- expanded enforcement of laws related to data protection and personal privacy,- increasing global enforcement of anti-bribery and anti-corruption laws, and - differing regulatory requirements and changes in those requirements.
We cannot predict the scope, timing, or impact of threatened U.S. tariffs on imports, the extent to which other countries may impose retaliatory trade restrictions, or the terms of future trade policy changes. Tariffs implemented during fiscal year 2025 increased our cost of revenue by approximately $25 million and reduced our gross margin by approximately $20 million, primarily affecting products manufactured in Europe for the U.S. market. While we have implemented mitigation strategies including manufacturing optimization, supplier collaboration, pricing adjustments, and temporary cost measures, these actions may not fully offset the impact of existing or future tariffs. Additional tariffs or trade restrictions may materially and adversely affect our results of operations, financial condition, and competitive position.
