Leidos Holdings, Inc.

U.S. GOVERNMENT MARKETS

During both the three and six months ended July 4, 2025, we generated approximately 87% of total revenues from contracts with the U.S. government as compared to 86% and 87% for the three and six months ended June 28, 2024, respectively. 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.

The federal government is currently operating under a continuing resolution that runs through September 30, 2025. Congress is currently working to advance the fiscal year 2026 appropriations bills with the goal of completing them by the end of the fiscal year.

INTERNATIONAL MARKETS

Sales to customers in international markets represented approximately 8% of total revenues for both the three and six months ended July 4, 2025, as compared to 9% and 8% for the three and six months ended June 28, 2024, respectively. 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.
