Segments
We currently have four reportable segments consisting of: 1) Medicaid; 2) Medicare; 3) Marketplace; and 4) Other. Our reportable segments are consistent with how we currently manage the business and view the markets we serve.
The Medicaid, Medicare, and Marketplace segments represent the government-funded or sponsored programs under which we offer managed healthcare services. The Other segment, which is insignificant to our consolidated results of operations, includes long-term services and supports consultative services in Wisconsin and the commercial portion of the business acquired in connection with the ConnectiCare transaction that closed effective February 1, 2025.
The key metrics used to assess the performance of our segments are revenue, margin and medical care ratio (“MCR”). MCR represents the amount of medical care costs as a percentage of premium revenue. Therefore, the underlying margin, or the amount earned by the segments after medical costs or service costs are deducted from revenue, represents the most important measure of earnings reviewed by management, and is used by our chief executive officer, who is our chief operating decision maker, to review results, assess performance, and allocate resources. Such oversight and decision making includes, among others, pricing, approving capital expenditures, and identifying growth opportunities. We do not report total assets by segment since this is not a metric used to assess segment performance or allocate resources.

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.
