NEW YORK--(BUSINESS WIRE)--Sep. 30, 2025-- Tamboran Resources Corporation (NYSE: TBN, ASX: TBN)

Tamboran Resources Corporation Chairman and Interim CEO, Richard Stoneburner, said:

“The transaction between Tamboran and Falcon is a logical consolidation of two of the Beetaloo Basin’s most active companies. The transaction will also strengthen Tamboran’s acreage position across the majority of the Beetaloo depocenter following the checkerboarding process with DWE.

“Tamboran will have approximately 2.9 million net prospective acres across the Beetaloo Basin, including 22.5% non-operating interest in all DWE checkers.

“Strategically, we believe this transaction will strengthen our ownership over the Phase 2 Development Area, where we are currently undertaking a farmout process with RBC Capital Markets. This will allow us to sell down a larger position to a new partner while maintaining a material working interest over acreage.

“We recognize Philip and the Falcon shareholders for their work in identifying the opportunity of the Beetaloo Basin and bringing in key historic partners including Hess Corporation and Origin Energy to help de-risk the play.”

Falcon Oil & Gas Ltd. Chief Executive Officer, Philip O'Quigley, said:

“This transaction brings Falcon’s shareholders’ interests in the Beetaloo directly to the centre of operations and provides our shareholders with greater exposure to all activities carried out by Tamboran.

“Upon closing of the transaction, Falcon shareholders will benefit from the increased exposure to the critically important pilot development currently underway in the Beetaloo. In addition, this transaction will remove any uncertainty around Falcon’s participation in the farmout of the Phase 2 Development Area, as previously announced by Tamboran.

It has been a pleasure to work with Dick Stoneburner and his team in bringing this transaction to our shareholders.”
