Business Segments Information
Note 10—Business Segments Information:
The Company has five customer facing business groups supported by the enterprise organizations, including the Innovation Factory. The five business groups, which are also its operating segments, are aggregated into two reportable segments for financial reporting purposes given the similarity in economic and qualitative characteristics, and based on the nature of the customers they serve. The Company’s two reportable segments are the Defense and Intelligence segment and the Civilian segment. The Company defines its operating segments based on the way the CODM, currently the Company's CEO, manages the operations for the purpose of allocating resources and assessing performance.
The Defense and Intelligence segment provides a diverse portfolio of national security solutions to the DoD and Intelligence Community of the United States Government.
The Civilian segment provides solutions to the civilian markets, encompassing federal, state, and local governments, in order to deliver services for citizen well-being, border security, and protecting lives. This includes integrating solutions into a spectrum of public service missions that impact travel, trade, health and the economy.
The offerings of both reportable segments entail the integration of emerging technologies into mission critical operations that modernize and enable national imperatives, including IT modernization, digital engineering, AI, mission systems support, training and simulation, and ground vehicles support. These services include end-to-end solutions spanning the design, development, integration, deployment, management and operations, sustainment and security of the customers’ entire IT infrastructure.
Costs associated with corporate functions that are not allocable to the reportable segments are presented as Corporate.
The CODM reviews and evaluates segment operating performance using segment "Revenues" and "Adjusted operating income (loss)". Adjusted operating income is a performance measure that primarily excludes the impact of non-recurring transactions and activities that the Company does not consider to be indicative of its ongoing operating performance. Adjusted operating income is calculated by taking operating income and excluding depreciation and amortization, acquisition, integration, restructuring, and impairment costs, and any other material non-recurring costs. The CODM uses revenues and adjusted operating income to assess the financial performance of each operating segment against pre-established performance targets and to allocate resources for strategic business decisions, including investments in certain products or services, potential acquisitions or divestitures, and capital deployment. Labor base is the significant expense that is regularly provided to the CODM, and primarily includes direct labor on customer contracts.
