Leidos Holdings, Inc.

U.S. GOVERNMENT MARKETS

During thethree and six months ended July 3, 2026, we generated approximately 83% and 85%, respectively, of total revenues from contracts with the U.S. government, as compared to 87% for both the three and six months ended July 4, 2025. Accordingly, our business performance is affected by the overall level of U.S. government spending, especially national security, homeland security and intelligence spending, and the alignment of our service and product offerings and capabilities with current and future budget priorities of the U.S. government.

While Congress continues to advance the government fiscal year 2027 appropriations bills, it is increasingly expected that lawmakers will rely on a short-term continuing resolution ("CR") to keep the government funded beyond the September 30, 2026 deadline. Failure to pass the appropriations bills or a CR by September 30, 2026, will result in a full or partial federal government shutdown.

INTERNATIONAL MARKETS

Sales to customers in international markets represented approximately 9% and 8% of total revenues for thethree and six months ended July 3, 2026, respectively, and as compared to 8% of total revenues for both thethree and six months ended July 4, 2025. Our international customers include foreign governments and their agencies. Our international business increases our exposure to international markets and the associated international regulatory, foreign currency exchange rate and geopolitical risks.

Changes in international trade policies, including higher tariffs on imported goods and materials, may increase the cost of certain goods necessary to fulfill our contractual requirements and for internal purposes. We expect to recover certain portions of the increase to the cost of goods through contractual measures. While we continue to evaluate the tariff environment and potential impacts of higher tariffs, we currently do not expect them to have a significant effect on our business.
