The deal must clear several regulatory and contractual conditions, including approval from the Australian Competition and Consumer Commission. Completion is anticipated during calendar 2027, with the final valuation set as of 31 March 2027.
What did Transurban Group management say?
Transurban CEO Michelle Jablko said:
Sydney is a core market for Transurban. WestConnex, Westlink M7 and NorthConnex provide options for Sydney motorists as they move around the city and will play an important role in supporting Sydney's growth for decades to come. We remain disciplined with how we allocate capital in our key markets of Australia and North America and we are committed to maintaining strong investment grade credit metrics.
What's next for Transurban Group?
Transurban expects to complete the acquisition in 2027 after securing all necessary approvals. The company has stressed its continuing commitment to strong credit metrics and investment-grade ratings, planning to refinance the acquisition debt into longer-term facilities over time.
Management highlighted that no equity raising is required and that the acquisition is expected to drive long-term growth in free cash per security, with only a minor short-term impact initially.
