Highlights

• Tamboran, as operator, and its joint venture partner Daly Waters Energy became the first to deliver gas sales from the Beetaloo Basin into the NT gas network. Volumes are currently limited by market demand, with Tamboran prioritizing two wells to assess long-term production and well performance data.

• The Beetaloo Joint Venture (BJV) successfully delivered the largest stimulation program in the Beetaloo Basin with three 10,000-foot laterals stimulated across 178 stages using the Liberty Energy (NYSE: LBRT) frac fleet. The program delivered an operational record in efficiency, achieving up to 12 stages per day.

• Successfully placed >2 million pounds of in-basin Beetaloo Red Sand (BRS) across ten stages within the SS2-5H well. The ability to use local sand provides a near-term opportunity for reducing completion costs.Further testing is planned for the December 2026 quarter campaign on the SS1 pad.

• Successfully completed construction of the Sturt Plateau Compression Facility (SPCF) on time and ~US$9million below forecast budget. Commissioning activities are expected to be completed during 4Q 2026.

• Commenced the 2026 three well drilling program on the SS1 pad with the Helmerich & Payne (NYSE: HP) FlexRig® Flex 3 rig. The SS1-4H and SS1-6H wells reached TD and have been cased with 9,329-foot and9,505-foot useable lateral sections, respectively. The SS1-2H well is currently being drilled.

• Drilling activities commenced on the Jibera South 1H (JS-1H) well in the Santos-operated EP 161 acreage (Tamboran 25%). The well is part of a two well program to further delineate gas resources in the Beetaloo East depocenter.

• In May 2026, Tamboran completed the acquisition of Falcon Oil & Gas Ltd. via the acquisition of its subsidiaries following receipt of final court approval from the Supreme Court of British Columbia.

• As of June 30, 2026, Tamboran had cash and expected near-term inflows of US$240 million (including Tamboran’s 50% share of restricted cash). Net drawn debt was US$30 million, associated with the construction of the SPCF, with undrawn debt of US$31 million (net Tamboran) remaining.

Tamboran Resources Corporation Chief Executive Officer, Todd Abbott, said:

“The last few months have been a pivotal period for Tamboran and the Beetaloo Basin as we have delivered on a key commitment and provided the next step in de-risking the basin. We have achieved first gas sales from the Beetaloo to the Northern Territory gas market. Homes and businesses in Darwin are now being powered by a local onshore resource.

“Our latest drilling and stimulation work is showing where we can improve efficiency and we delivered the compression facility on time and below the forecasted budget, while local sand offers a potential source of completion cost savings. The equity raise has also strengthened our balance sheet as we progress towards the next phase of development. “The priority now is to turn those achievements into sustained operating performance. That means completing commissioning and production testing, building towards plateau production and contracted supply of 40 TJ/d, and demonstrating that the gains in well delivery can be repeated. Those are the measures I will use to judge our progress as we advance our development plans and partner discussions. “First gas also delivers real benefits for the Northern Territory: new jobs, opportunities for local business, and a reliable domestic gas supply that supports the Territory's economic growth.”
