SEGMENT INFORMATION
We conduct our business primarily through two reportable segments: (1) oil and natural gas exploration and production and (2) carbon management. We identified these segments based on the nature of their activities, the types of products sold and services to be provided. Our oil and natural gas segment explores for, develops, and produces oil and condensate, natural gas liquids and natural gas. Our carbon management segment, that we refer to as Carbon TerraVault, is expected to build, install, operate and maintain CO2 capture equipment, transportation assets and storage facilities. Our oil and natural gas segment operates assets located in California and Utah. Our carbon management segment operates exclusively in California.

Our chief operating decision maker (CODM), the Chief Executive Officer, uses segment profit or loss to assess the performance of each business, as well as our overall performance, and to make decisions about resources to be allocated to each segment, including capital investments.

The following tables provide segment profit or loss and reconciliations to consolidated income before income taxes for the years ended December 31, 2025, 2024, and 2023. The consolidation and elimination entries necessary to arrive at our consolidated financial information is presented separately.

See Note 4 Investments and Related Party Transactions for information on our investment in the Carbon TerraVault JV, which is part of our carbon management segment. See Note 13 Leases for information leases we have entered into for our carbon management business. Included in our oil and gas segment is $659 million of oil and gas property, inclusive of C&J Well Services, we acquired in the Berry Merger and $3 billion of oil and gas property acquired in the Aera Merger. Refer to Note 2 Business Combinations for additional information on these transactions.

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.
