Segmented and geographic information
Operating segment
The Company only has one operating segment: rail transportation.

The Company's chief operating decision-maker ("CODM") is the Company's Chief Executive Officer. The CODM uses "Net income attributable to controlling shareholders" to assess the Company's performance and decide on the allocation of resources. "Net income attributable to controlling shareholders" is used in conjunction with certain Non-GAAP measures, operational performance indicators, and figures prepared on a forecast basis to evaluate the return on the Company's assets and make operational and investment decisions. The Company's significant segment expenses are consistent with the expenses presented on the Company's Consolidated Statements of Income.

For the years ended December 31, 2025, 2024, and 2023, no single customer accounted for more than 10% of "Total revenues".

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.
