Forward-looking statements are all statements other than statements of historical facts. The words “anticipate,” “believe,” “ensure,” “expect,” “if,” “intend,” “estimate,” “probable,” “project,” “forecasts,” “predict,” “outlook,” “aim,” “will,” “could,” “should,” “would,” “potential,” “may,” “might,” “likely,” “plan,” “positioned,” “strategy,” and similar expressions or other words of similar meaning, and the negatives thereof, are intended to identify forward-looking statements. Specific forward-looking statements include statements regarding Tamboran’s plans and expectations with respect to the anticipated impact of the transaction on the combined company’s results of operations, financial position, growth opportunities and competitive position.

The forward-looking statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. It is possible that Tamboran’s future financial performance may differ from expectations due to a variety of factors, including but not limited to: Tamboran’s ability to integrate Falcon's operations and assets in a successful manner and in the expected time period and the possibility that any of the anticipated benefits and projected synergies of such acquisition will not be realized or will not be realized within the expected time period; our early stage of development with no material revenue expected until the second half of 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 Company’s filings with the Securities and Exchange Commission. These factors are not necessarily all of the factors that could cause Tamboran’s actual results, performance, or achievements to differ materially from those expressed in or implied by any of the forward-looking statements.

Other unknown or unpredictable factors also could harm Tamboran’s results. Additional factors that could cause results to differ materially from those described above can be found in Tamboran’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, and subsequent Quarterly Reports on Form 10-Q, which are on file with the Securities and Exchange Commission (the “SEC”) and available from Tamboran’s website at www.tamboran.com under the “Investor Relations” tab, and in other documents Tamboran files with the SEC.
