NEW YORK & SYDNEY--(BUSINESS WIRE)--Dec 17, 2025--

Stonepeak, a leading alternative investment firm specializing in infrastructure and real assets, today announced that it has entered into a definitive agreement to acquire Allgas, a leading gas distribution network located in Queensland, Australia, from the APA Group (ASX: APA), Marubeni Corporation, and other shareholders.

Allgas is the provider of gas haulage infrastructure in the catchment area spanning Brisbane to the northern tip of New South Wales, and separately, Toowoomba and Oakey. Its extensive network includes approximately 3,900kms of distribution mains that supply approximately 120,000 households and businesses, nine gate stations, and 123,000 metering devices. Through its connection to major Queensland supply hubs and the extensive reserves available in the region, Allgas serves as a reliable source of energy distribution for its customers.

“This transaction underscores Stonepeak’s long-held conviction in natural gas as an essential component of the energy mix supporting global energy transition efforts, especially in Australia where it continues to play an important role for businesses and individuals,” said Darren Keogh, Senior Managing Director at Stonepeak. “Queensland, and South East Queensland in particular, is experiencing significant economic expansion underpinned by population and productivity growth that is supported by the Allgas network. We look forward to working with Allgas to help effectively capitalize on these meaningful tailwinds.”

The transaction is subject to regulatory approvals and is expected to close in the first half of 2026.
