ASGN provides IT solutions across the commercial and government sectors. ASGN operates through two segments, Commercial and Federal Government. The Commercial Segment, which is the largest segment, provides consulting, creative digital marketing, and permanent placement services primarily to Fortune 1000 and large mid-market companies. The Federal Government Segment provides advanced IT solutions in data and AI, cybersecurity, and enterprise transformation to the following four customer types: (i) Defense and Intelligence, (ii) National Security, (iii) Federal Civilian, and (iv) other clients. Virtually all of the Company's revenues are generated in the United States.

The Company's chief executive officer ("CEO") is the chief operating decision maker and he reviews revenues, gross profit and operating income for each segment. He also considers forecast-to-actual variances on a monthly basis for these financial measures when making decisions about allocating resources to the segments and uses these segment financial measures in the annual budget process. The CEO does not evaluate, manage or measure performance of segments using asset information. Accordingly, assets by reportable segment are not disclosed. Segment information is as follows (in millions):

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
