HUNTINGTON INGALLS INDUSTRIES, INC.

8. SEGMENT INFORMATION

The Company is organized into three operating segments, which are also its reportable segments: Ingalls, Newport News, and Mission Technologies, consistent with HII’s principal lines of business. Ingalls includes the Company’s non-nuclear ship design, construction, repair, and maintenance businesses. Newport News includes all of the Company’s nuclear ship design, construction, overhaul, refueling, and repair and maintenance businesses. The Mission Technologies segment provides a wide range of services and products, including command, control, computers, communications, cyber, intelligence, surveillance, and reconnaissance systems and operations; the application of artificial intelligence and machine learning to battlefield decisions; defense and offensive cyberspace strategies and electronic warfare; unmanned autonomous systems; live, virtual, and constructive training solutions; platform modernization; and critical nuclear operations.

The Company’s operations are managed by senior executives reporting to the Company’s President and Chief Executive Officer, the chief operating decision maker, who regularly reviews the reportable segments’ operating results to assess performance and allocate resources.

The Company internally manages operations by reference to segment operating income, which is defined as operating income before the Operating FAS/CAS Adjustment and non-current state income taxes, neither of which affects contract performance. In evaluating operating performance, the chief operating decision maker looks primarily at changes in sales and service revenues, as well as segment operating income. This approach is consistent with the long-term life cycle of the Company’s contracts, as management assesses the bidding of each contract by focusing on net sales and operating profit and monitors performance in a similar manner through contract completion.

The Operating FAS/CAS Adjustment represents the difference between the service cost component of the Company's pension and other postretirement benefit plan expense determined in accordance with GAAP ("FAS") and the Company's pension and other postretirement expense under CAS.

U.S. Government Sales- Revenues from the U.S. Government include revenues from contracts for which HII is the prime contractor, as well as contracts for which the Company is a subcontractor and the ultimate customer is the U.S. Government. The Company derived substantially all of its revenues from the U.S. Government for each of the years ended December 31, 2025, 2024, and 2023.

Assets- Substantially all of the Company's assets are located or maintained in the United States.
