Tamboran to acquire Falcon Oil & Gas Ltd. to create ~2.9-million-acre Beetaloo Basin business

30 September 2025

Highlights

• Falcon Oil & Gas Ltd. (TSXV: FO, AIM: FOG) ( Falcon ) and Tamboran Resources Corporation (NYSE: TBN, ASX: TBN) ( Tamboran ) have entered into a definitive agreement to create an ~2.9 million net prospective acre business across the majority of the Beetaloo depocenter ( Transaction ).
• The combination of Tamboran and Falcon is a logical consolidation of two leading Beetaloo Basin businesses and creates a company with a pro forma market capitalization of >US$500 million.
• Under the Transaction, Tamboran will acquire Falcon via the acquisition of all its subsidiaries in exchange for 6,537,503 shares of Tamboran NYSE Common Stock and cash consideration of US$23.7 million.
• On completion, Falcon will distribute Tamboran shares to eligible shareholders at an exchange ratio of 0.00687 shares of Tamboran NYSE Common Stock for each Falcon Common Stock. These shareholders are expected to own ~26.8% of the pro forma business.
• The Transaction values Falcon's subsidiaries at C$239 million (Stg£128 million), at an implied offer price of C$0.2154 (Stg£0.1152) per share. This reflects a 19.7% premium of the closing price of Falcon on the TSX on September 29, 2025 and a 53.2% premium to the 90-day traded VWAP.
• The Transaction aims to strengthen Tamboran's working interest in the Phase 2 Development Area to 80.62% ahead of the previously announced farmout process and creates further alignment with Daly Waters Energy, LP (DWE) across the entire EP 76, 98 and 117 acreage following completion of the previously announced checkerboard process.
• The Transaction has been unanimously approved by the Board of Directors of Tamboran and Falcon.
• The Transaction is expected to close by the first quarter of 2026, subject to satisfaction of closing conditions, including the approval by Falcon shareholders of the Transaction pursuant to Rule 15 of the AIM Rules for Companies and applicable Canadian corporate and securities laws and the approval by Tamboran stockholders of the issuance of the Tamboran Common Stock.
• The Transaction will on completion result in Falcon ceasing to own all of its assets and business; accordingly, Falcon also intends to seek shareholder approval for the cancellation of its shares from trading on the AIM market of the London Stock Exchange and the TSX Venture Exchange ( Cancellation ), conditional on closing of the Transaction. Further details will be announced in due course.
• The entities being acquired pursuant to the Transaction are Falcon's wholly owned subsidiaries TXM Oil and Gas Exploration Kft., a Hungarian limited liability company; Falcon Oil & Gas Ireland Ltd., an Irish limited liability company; Falcon Oil & Gas Holdings Ireland Ltd., an Irish limited liability company; Falcon Exploration and Production South Africa (Pty) Ltd., a South African limited liability company and Falcon's 98.1% majority owned subsidiary, Falcon Oil & Gas Australia Limited, an Australian limited liability company (the Subsidiaries ). In the twelve months to 31 December 2024, the subsidiaries reported a loss for the year of US$2.2 million and total assets of US$60.7 million.

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.”

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 and will strengthen Tamboran's acreage position across the majority of the Beetaloo depocenter following the checkerboarding process with Daly Waters Energy, LP. ( DWE ).

Tamboran will have approximately 2.9 million net prospective acres across the Beetaloo Basin, including a 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.”
