Section B: Notes to the Group financial statements for the year ended 30 June 2025
Operating performance
B4 Segment information In the segment information provided to the Transurban Group Executive Committee (certain members of which act as the chief operating decision maker), segments are defined by the geographical region in which the Group operates being Melbourne, Sydney, Brisbane and North America. The Group's corporate function is not an operating segment under the requirements of AASB 8 Operating Segments as its revenue generating activities are only incidental to the business. The Transurban Group Executive Committee assesses the performance of each geographical region based on proportional EBITDA. During the period, the Group revised the basis of measurement of proportional EBITDA. From 1 July 2024, proportional EBITDA is based on a measure of proportional earnings, adjusted for major maintenance spend and before depreciation, amortisation, net finance costs, income taxes and mark-to-market movements in power purchase agreements. The revised proportional EBITDA definition is more aligned to operational performance, removes timing impacts and variability, and reflects the contribution of each geographical region in the Group in the proportion of Transurban's equity ownership. Proportional operating EBITDA is proportional EBITDA excluding non-recurring items, which may include, among other things, transaction, integration, litigation liability and restructuring costs. The diagram below shows the concession assets included in each geographical region, together with the ownership interests held by the Group as at 30 June 2025:
1. Westlink M7 and NorthConnex (NCX) together form NWRG. 2. The M4, M8/M5 East and M4-M8 link together form WestConnex (STP JV).
