The transaction is subject to certain conditions precedent and regulatory approvals.

DWE will have participation rights to any transaction on the same terms.
• Ownership of the proposed northern Pilot Area, which will provide initial gas production to the Northern Territory, remains unchanged (Tamboran 47.5% operator) with expansion into the proposed southern Pilot Area (Tamboran 38.75%) anticipated in accordance with the terms of the acreage sale. Future working interests are subject to participation of parties in the Joint Venture.

Tamboran Resources Corporation Chief Executive Officer, Joel Riddle, said:

“We have engaged RBC Capital Markets to progress a farm down of acreage to carry Tamboran through the delineation of gas resources to underpin our Phase 2 strategy.

“Tamboran and DWE will continue working together on the Pilot Area, where we are focused on the development of the proposed 40 MMcf/d Shenandoah South Pilot Project. Tamboran’s recently secured funding is expected to support the drilling activities required to reach initial production in mid-2026, subject to weather and customary regulatory approvals.

“DWE will also participate in our Phase 2 Development Area and we look forward to continuing to work with DWE on progressing our joint ambition to be a major gas supplier to the East Coast gas market at a time when the market is anticipating a shortfall at the back end of the decade.”

The transaction is subject to certain conditions precedent including, and not limited to, DWE obtaining approval from the Formentera Australia Fund, LP’s Limited Partner Advisory Committee, Tamboran shareholder approval and regulatory approvals.

Note on Forward-Looking Statements

This press release contains “forward-looking” statements related to the Company within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Section 27A of the Securities Act of 1933, as amended. Forward-looking statements reflect the Company’s current expectations and projections about future events at the time, and thus involve uncertainty and risk. The words “believe,” “expect,” “anticipate,” “will,” “could,” “would,” “should,” “may,” “plan,” “estimate,” “intend,” “predict,” “potential,” “continue,” “participate,” “progress,” “conduct” and the negatives of these words and other similar expressions generally identify forward-looking statements.

It is possible that the Company’s future financial performance may differ from expectations due to a variety of factors, including but not limited to: our early stage of development with no material revenue expected until 2026 and our limited operating history; the substantial additional capital required for our business plan, which we may be unable to raise on acceptable terms; our strategy to deliver natural gas to the Australian East Coast and select Asian markets being contingent upon constructing additional pipeline capacity, which may not be secured; the absence of proved reserves and the risk that our drilling may not yield natural gas in commercial quantities or quality; the speculative nature of drilling activities, which involve significant costs and may not result in discoveries or additions to our future production or reserves; the challenges associated with importing U.S. practices and technology to the Northern Territory, which could affect our operations and growth due to limited local experience; the critical need for timely access to appropriate equipment and infrastructure, which may impact our market access and business plan execution; the operational complexities and inherent risks of drilling, completions, workover, and hydraulic fracturing operations that could adversely affect our business; the volatility of natural gas prices and its potential adverse effect on our financial condition and operations; the risks of construction delays, cost overruns, and negative effects on our financial and operational performance associated with midstream projects; the potential fundamental impact on our business if our assessments of the Beetaloo are materially inaccurate; the concentration of all our assets and operations in the Beetaloo, making us susceptible to region-specific risks; the substantial doubt raised by our recurring operational losses, negative cash flows, and cumulative net losses about our ability to continue as a going concern; complex laws and regulations that could affect our operational costs and feasibility or lead to significant liabilities; community opposition that could result in costly delays and impede our ability to obtain necessary government approvals; exploration and development activities in the Beetaloo that may lead to legal disputes, operational disruptions, and reputational damage due to native title and heritage issues; the requirement to produce natural gas on a Scope 1 net zero basis upon commencement of commercial production, with internal goals for operational net zero, which may increase our production costs; the increased attention to ESG matters and environmental conservation measures that could adversely impact our business operations; risks related to our corporate structure; risks related to our common stock and CDIs; and the other risk factors discussed in the this report and the Company’s filings with the Securities and Exchange Commission.

It is not possible to foresee or identify all such factors. Any forward-looking statements in this document are based on certain assumptions and analyses made by the Company in light of its experience and perception of historical trends, current conditions, expected future developments, and other factors it believes are appropriate in the circumstances. Forward-looking statements are not a guarantee of future performance and actual results or developments may differ materially from expectations. While the Company continually reviews trends and uncertainties affecting the Company’s results of operations and financial condition, the Company does not assume any obligation to update or supplement any particular forward-looking statements contained in this document.
