SEGMENT INFORMATION
The Company operates in and reports as a single reportable segment as the CODM does not evaluate profitability nor evaluate performance or allocate resources below the level of the consolidated Company. The accounting policies of the segment are the same as those described in the summary of significant accounting policies. The CODM reviews Net income (loss) attributable to Oscar Health, Inc. and Earnings from operations presented on a consolidated basis for purposes of
allocating resources and evaluating financial performance. These metrics serve as benchmarks to evaluate the business, measure performance, identify trends, prepare financial projections, and make strategic decisions. The CODM does not evaluate performance or allocate resources based on segment assets data; therefore, total segment assets are not presented.

The following table presents the revenue, significant expenses, and net income (loss) for the Company’s segment. As the Company operates and reports as a single segment, its measure of segment net income (loss) is the same as Net income (loss) attributable to Oscar Health, Inc. on the Consolidated Statements of Operations.

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.
