On October 15, 2024, we completed the EnLink Controlling Interest Acquisition. Our 2024 results include the impact of the EnLink Controlling Interest Acquisition from the period of October 15, 2024, to December 31, 2024, across all four of our existing operating segments. On October 31, 2024, we completed the Medallion Acquisition. Our 2024 results include the impact of the Medallion Acquisition from the period of November 1, 2024, to December 31, 2024, in our Refined Products and Crude segment.
Other and eliminations consist of corporate costs, the operating activities of our headquarters building and related parking facility, the activity of our wholly owned captive insurance company and eliminations necessary to reconcile our reportable segments to our Consolidated Financial Statements.
For the years ended December 31, 2025, and December 31, 2023, revenues from one customer impacting all our segments represented approximately 12% and 11% of our consolidated revenues, respectively. For the year ended December 31, 2024, we had no single customer from which we received 10% or more of our consolidated revenues.
The significant expense categories and amounts included in the table below align with the segment-level information that is regularly provided to the chief operating decision-maker.

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.
