The following risk factor supplements the risk factors included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2025.

We are subject to risks from the continuation of the ongoing U.S. federal government shutdown.

Our business is exposed to operational and financial disruptions caused by the U.S. federal government shutdown that began on October 1, 2025. The ongoing U.S. federal government shutdown may result in us experiencing delays or decreases in customer orders with the U.S. DoD or with our prime contractor customers or potentially the suspension of work on contacts in progress or in payment delays related to the funding status of different programs. The shutdown has also slowed the processing of export licenses by agencies such as the Department of State’s Directorate of Defense Trade Controls and the Department of Commerce’s Bureau of Industry and Security. These export license delays could hinder our ability to fulfill international orders and potentially subject us to increased costs for liquidated damages or other penalties for late deliveries. Given the indefinite nature of the current shutdown and the absence of a clear resolution timeline, we anticipate continued volatility in the federal contracting environment. If the shutdown persists for an extended timeframe, it could materially and adversely affect our results of operations and financial performance.
