DOWNER EXPANDS ITS SERVICES FOR TRANSURBAN IN NSW

Downer EDI Limited (Downer) today announced it had been awarded contracts of up to nine years to
provide road maintenance and incident response services on Transurban’s Northern assets in Sydney,
NSW.

Downer will commence delivery of services under the NSW Incident Response and Maintenance Services
(North Region) contracts in July 2026 for an initial seven-year term, with the option for two one-year
extensions. Total revenue to Downer over the full nine-year term is approximately $310 million.

The new contracts cover Transurban’s northern assets, comprising the NorthConnex tunnel (which Downer
has maintained since 2020), M2 Motorway, and Lane Cove Tunnel.

Under the contracts, Downer will deliver 24/7 incident response and maintenance services, including civil
maintenance, and mechanical and electrical services – involving preventative and corrective maintenance of
critical assets including fire systems, water treatment plants, air quality monitoring systems, and tunnel
ventilation.

The new contracts extend Downer’s long-term relationship with Transurban in New South Wales and build
on the successful partnership in Victoria where Downer maintains CityLink and West Gate Tunnel in
Melbourne.

The Chief Executive Officer of Downer, Peter Tompkins, said Downer is proud to extend its partnership with
Transurban and continue delivering on a shared commitment to safe, reliable and resilient road networks.

“Our expanded role in New South Wales reflects a strong endorsement of our asset management expertise
and the consistent high-quality services delivered by our teams across the Transurban network,” Mr
Tompkins said.

“With more than 50,000 kilometres of road networks under management across Australia and New Zealand,
Downer brings significant scale and deep expertise in asset management and operations. We look forward
to applying this capability to support the performance and resilience of Transurban’s assets linking between
people, places and progress.”
