FORWARD-LOOKING STATEMENTS

This Proxy Statement contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Forward-looking statements can be identified by words such as: “anticipate,” “intend,” “plan,” “goal,” “commit,” “seek,” “believe,” “project,” “estimate,” “expect,” “strategy,” “future,” “likely,” “may,” “should,” “will” and similar references to future periods.

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 environmental, social and governance 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; the ability of the Company to satisfy the conditions to consummate the Offering; and the other risk factors discussed in this statement and the Company’s filings with the Securities and Exchange Commission (the “SEC”).

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, except as required by law.

What happens if other business not discussed in this Proxy Statement comes before the meeting?

The Company does not know of any business to be presented at the Special Meeting other than the proposals discussed in this Proxy Statement. If other business properly comes before the meeting under our Certificate of Incorporation, Amended and Restated Bylaws, and rules established by the SEC, the proxies will use their discretion in casting all the votes that they are entitled to cast.

Who is entitled to vote?

As of the Record Date, 20,493,869 shares of Common Stock were outstanding. Only holders of record of our Common Stock as of the Record Date will be entitled to notice of, and to vote at, the Special Meeting or any adjournment or postponement thereof. Each stockholder is entitled to one vote for each share of our Common Stock held by such stockholder on the Record Date. No cumulative voting rights are authorized. Each CDI holder is entitled to direct the Depositary Nominee to vote one vote for every 200 CDIs held by such holder on the Record Date.

What does it mean to be a holder of CDIs?

CDIs are issued by the Company through the Depositary Nominee and traded on the Australian Securities Exchange. If you own CDIs, then you are the beneficial owner of one share of Common Stock for every 200 CDIs that you own. The Depositary Nominee, or its custodian, is considered the stockholder of record for the purposes of voting at the Special Meeting. As the beneficial owner, you have the right to direct the Depositary Nominee, or its custodian, as to how to vote the shares of Common Stock underlying your CDIs. As a beneficial owner, you are invited to attend the Special Meeting as a guest.

However, because you are not a holder of Common Stock, if you personally want to vote the shares of Common Stock underlying your CDIs at the Special Meeting, you must inform the Depositary Nominee via the CDI Voting Instruction Form that you wish to nominate yourself (or another person) to be appointed as the Depositary Nominee’s proxy for the purposes of virtually attending and voting at the Special Meeting.

Under the rules governing CDIs, the Depositary Nominee is not permitted to vote on your behalf on any matter to be considered at the Special Meeting unless you specifically instruct the Depositary Nominee how to vote. We encourage you to communicate your voting instructions to the Depositary Nominee in advance of the Special Meeting to ensure that your vote will be counted by completing the CDI Voting Instruction Form and returning it in accordance with the instructions specified on that form.

How do I vote in advance of the Special Meeting?

If you are a holder of record of shares of Common Stock, you may direct your vote without attending the Special Meeting by following the instructions on the proxy card to vote by Internet or by telephone, or by signing, dating, and mailing a proxy card.

If you hold your shares in street name via a broker, bank, or other nominee, you may direct your vote without attending the Special Meeting by signing, dating, and mailing your voting instruction card. Internet or telephonic voting may also be available. Please see your voting instruction card provided by your broker, bank, or other nominee for further details.

How do I vote during the Special Meeting?

Shares held directly in your name as the stockholder of record may be voted if you are attending the Special Meeting by entering the 16-digit control number found on your proxy card when you log in to the meeting at www.virtualshareholdermeeting.com/TBN2026SM.

Shares held in street name through a brokerage account or by a broker, bank, or other nominee may only be voted at the Special Meeting by submitting voting instructions to your bank, broker or other nominee or by presenting a legal proxy, issued in your name from the record holder (your bank, broker or other nominee).

Even if you plan to attend the Special Meeting, we recommend that you vote in advance, as described above under “How do I vote in advance of the Special Meeting?” so that your vote will be counted if you are unable to attend the Special Meeting.

How do I vote if I hold CDIs?

Each CDI holder is entitled to direct the Depositary Nominee to vote one vote for every 200 CDIs held by such holder on the Record Date. Persons holding CDIs are entitled to receive notice of and to attend the Special Meeting as guests. Holders of CDIs may direct the Depositary Nominee to vote their underlying Common Stock at the Special Meeting by completing and returning the CDI Voting Instruction Form to Boardroom Pty Ltd (“Boardroom”), the agent the Company has designated for the collection and processing of voting instructions from the Company’s CDI holders. Votes must be received by Boardroom by no later than 5:00 p.m. Central time on Sunday, January 11, 2026 (being 8:00 a.m. AEDT on Monday, January 12, 2026) (48 hours prior to the date of the Special Meeting) in accordance with the instructions on the CDI Voting Instruction Form.

Alternatively, CDI holders can inform the Depositary Nominee via the CDI Voting Instruction Form that they wish to nominate themselves (or another person) to be appointed as the Depositary Nominee’s proxy for the purposes of virtually attending and voting at the Special Meeting.

Can I change my vote or revoke my proxy or CDI Voting Instruction Form?

You may change your vote or revoke your proxy at any time before it is voted at the Special Meeting. If you are a stockholder of record, you may change your vote or revoke your proxy by:

 

•

delivering to the attention of the Secretary at the address on the first page of this Proxy Statement a written notice of revocation of your proxy;

 

•

delivering to us an authorized proxy bearing a later date (including a proxy over the Internet or by telephone); or

 

•

attending the Special Meeting and voting electronically, as indicated above under “How do I vote during the Special Meeting?,” but note that attendance at the Special Meeting will not, by itself, revoke a proxy.

If your shares are held in the name of a bank, broker, or other nominee, you may change your vote by submitting new voting instructions to your bank, broker, or other nominee. Please note that if your shares are held of record by a bank, broker, or other nominee and you decide to attend and vote at the Special Meeting, your vote at the Special Meeting will not be effective unless you present a legal proxy, issued in your name from the record holder (your bank, broker, or other nominee).

If you are a holder of CDIs and you direct the Depositary Nominee to vote by completing the CDI Voting Instruction Form, you may revoke those instructions by delivering to Boardroom a written notice of revocation bearing a later date than the CDI Voting Instruction Form previously sent, which notice must be received by no later than 5:00 p.m. Central time on Sunday, January 11, 2026 (being 8:00 a.m. AEDT on Monday, January 12, 2026).

What is a broker nonvote?

Brokers, banks, or other nominees holding shares on behalf of a beneficial owner (other than the Depositary Nominee) may vote those shares in their discretion on certain “routine” matters even if they do not receive timely voting instructions from the beneficial owner. With respect to “nonroutine” matters, the broker, bank, or other nominee is not permitted to vote shares for a beneficial owner without timely received voting instructions. Each of the Proposals are nonroutine matters.

A broker nonvote occurs when a broker, bank, or other nominee does not vote on a nonroutine matter because the beneficial owner of such shares has not provided voting instructions with regard to such matter. Broker nonvotes may occur as to the other Proposals or any other nonroutine matters that are properly presented at the Special Meeting. The effect of broker nonvotes on each of the other Proposals is described below.

What constitutes a quorum?

The presence at the Special Meeting, either virtually or by proxy, of the holders of not less than a majority in voting power of the outstanding shares of stock entitled to vote at the Special Meeting shall be necessary and sufficient to constitute a quorum. Abstentions and broker nonvotes will be counted as present for the purpose of determining whether there is a quorum at the Special Meeting. Your shares are counted as being present if you participate virtually at the Special Meeting and cast your vote online during the meeting prior to the closing of the polls by visiting www.virtualshareholdermeeting.com/TBN2026SM, or if you vote by proxy via the Internet, by telephone, or by returning a properly executed and dated proxy card or voting instruction form by mail.

What is the deadline for submitting a proxy or CDI Voting Instruction Form?

To ensure that proxies are received in time to be counted prior to the Special Meeting, proxies submitted by Internet or by telephone should be received by 11:59 p.m. Eastern time on Monday, January 12, 2026, and proxies submitted by mail should be received by the close of business on Monday, January 12, 2026 (the business day prior to the date of the Special Meeting).

CDI Voting Instruction Forms must be received by Boardroom by no later than 5:00 p.m. Central time on Sunday, January 11, 2026 (being 8:00 a.m. AEDT on Monday, January 12, 2026) (48 hours prior to the date of the Special Meeting) in accordance with the instructions on the CDI Voting Instruction Form.

What does it mean if I receive more than one proxy card or CDI Voting Instruction Form?

If you hold your shares or CDIs in more than one account, you will receive one proxy card or CDI Voting Instruction Form for each account (as applicable). To ensure that all of your shares or CDIs are voted, please complete, sign, date, and return one proxy card or CDI Voting Instruction Form for each account or use the proxy card for each account to vote by Internet or by telephone.

How will my shares be voted if I return a blank proxy card or a blank CDI Voting Instruction Form?

If you are a holder of record of our Common Stock and you sign and return a proxy card or CDI Voting Instruction Form or otherwise submit a proxy without giving specific voting instructions, your shares will be voted in accordance with the Board’s recommendations. If you hold your shares in street name via a broker, bank, or other nominee and do not provide the broker, bank, or other nominee with voting instructions (including by signing and returning a blank voting instruction card), your shares:

 

•

will be counted as present for purposes of establishing a quorum;

 

•

will be voted in accordance with the broker’s, bank’s, or other nominee’s discretion on “routine” matters; and

 

•

will not be counted in connection with the other Proposals or any other nonroutine matters that are properly presented at the Special Meeting. For each of these proposals, your shares will be treated as “broker nonvotes.”

Our Board knows of no matter to be presented at the Special Meeting other than Proposals identified in this Proxy Statement. If any other matters properly come before the Special Meeting upon which a vote properly may be taken, shares represented by all proxies received by us will be voted with respect thereto as permitted and in accordance with the judgment of the proxy holders.

Why is the Company Seeking Stockholder Approval of Proposal 2?

Because our Common Stock is listed on the New York Stock Exchange (“NYSE”), we are subject to the NYSE’s rules and regulations. Section 312.03 of the NYSE Listed Company Manual requires stockholder approval prior

to the issuance of common stock, or securities convertible into or exercisable for common stock, in any transaction or series of related transactions, subject to certain exceptions, in which:

 

•

the common stock or securities convertible into or exercisable for common stock are issued to a director, officer, a controlling shareholder or member of a control group or any other substantial security holder of the company that has an affiliated person who is an officer or director of the company (an “Active Related Party”) if the number of shares of common stock to be issued, or if the number of shares of common stock into which the securities may be convertible or exercisable, exceeds either (i) one percent of the number of shares of common stock, or (ii) one percent of the voting power outstanding before the issuance (the “NYSE Active Related Party Cap”);

 

•

a director, officer or substantial security holder of the company (each a “Related Party”) has a five percent or greater interest (or such persons collectively have a ten percent or greater interest), directly or indirectly, in the consideration to be paid in the transaction or series of related transactions and the present potential issuance of common stock, or securities convertible into common stock, could result in an issuance that exceeds either five percent of the number of shares of common stock or five percent of the voting power outstanding before the issuance (the “NYSE Related Party Cap”); or

 

•

(i) the common stock has, or will have upon issuance, voting power equal to or in excess of 20 percent of the voting power outstanding before the issuance of such stock or securities convertible into or exercisable for common stock, or (ii) the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20 percent of the number of shares of common stock outstanding before the issuance of the common stock or of securities convertible into or exercisable for common stock (the “NYSE 20% Cap” and together with the NYSE Active Related Party Cap and NYSE Related Party Cap, the “NYSE Thresholds”).

The approval of the Company’s stockholders is required under the NYSE listing rules, because the PIPE Investors (as defined below) may be deemed to be an Active Related Party and/or a Related Party under NYSE listing rules, and the shares of common stock underlying the October 2025 PIPE Financing to be issued to PIPE Investors may exceed the NYSE Thresholds.

Why is the Company Seeking Stockholder Approval of Proposal 15?

Because our Common Stock is listed on the NYSE, we are subject to the NYSE’s rules and regulations. Section 303A.08 of the NYSE Listed Company Manual requires stockholder approval of any equity compensation plan. The issuance of the TBN Shares (as defined below) to the TBN PIPE Investors (as defined below) in the October 2025 PIPE Financing at a discount, offered outside the Company’s 2024 Incentive Award Plan, may be considered an “equity-compensation plan” under Section 303A.08 of the NYSE Listed Company Manual.

Who will count the vote?

Broadridge Financial Solutions, Inc., or their appointed representative, will serve as the inspector of elections and will certify the voting results.

Will a stockholder list be available for inspection?

A list of stockholders entitled to vote at the Special Meeting will be available for inspection by stockholders for any purpose germane to the meeting for 10 business days prior to the Special Meeting, at Tamboran Resources Corporation, Suite 01, Level 39, Tower One, International Towers Sydney, 100 Barangaroo Avenue, Barangaroo NSW 2000 between the hours of 9:00 a.m. and 5:00 p.m. AEDT. The stockholder list will also be available to stockholders of record for examination during the Special Meeting at www.virtualshareholdermeeting.com/TBN2026SM. You will need the control number included on your proxy card, or voting instruction form, or otherwise provided by your bank, broker, or other nominee.

What is “householding” and how does it affect me?

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, we send only one Proxy Statement and one Annual Report to eligible stockholders who share a single address, unless we have received instructions to the contrary from any stockholder at that address. This practice is designed to eliminate duplicate mailings, conserve natural resources, and reduce our printing and mailing costs. Stockholders who participate in householding will continue to receive separate proxy cards.

If you share an address with another stockholder and receive only one set of proxy materials but would like to request a separate copy of these materials, please contact our mailing agent, Broadridge, by calling (866) 540-7095 or writing to Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717, and an additional copy of proxy materials will be promptly delivered to you. Similarly, if you receive multiple copies of the proxy materials and would prefer to receive a single copy in the future, you may also contact Broadridge at the above telephone number or address. If you own shares through a bank, broker, or other nominee, you should contact the nominee concerning householding procedures.

How can I find out the results of the voting at the Special Meeting?

We will announce preliminary voting results at the Special Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Special Meeting.

Whom can I contact for further information?

You may request additional copies, without charge, of this Proxy Statement and other proxy materials or ask questions about the Special Meeting, the proposals, or the procedures for voting your shares by writing to our Corporate Secretary at Suite 01, Level 39, Tower One, International Towers Sydney, 100 Barangaroo Avenue, Barangaroo NSW 2000.

The Company is seeking Stockholder ratification and approval pursuant to ASX Listing Rule 7.4 for the issue of the Public Offering Common Stock that were issued using the Company’s 15% placement capacity for the purposes of ASX Listing Rule 7.1.

Broadly speaking, and subject to a number of exceptions, ASX Listing Rule 7.1 limits the number of equity securities that a listed entity can issue without the approval of its stockholders over any 12-month period to 15% of the number of fully paid ordinary shares it had on issue at the start of that period. However, in accordance with ASX Listing Rule 7.4, an issue of securities made without approval under ASX Listing Rule 7.1 is treated as having been made with approval if:

 

•

the issue did not breach ASX Listing Rule 7.1; and

 

•

the issue is subsequently approved or ratified by shareholders.

ASX Listing Rule 7.4 allows the stockholders of a listed company to approve an issue of equity securities after it has been made or agreed to be made. If they do, the issue is taken to have been approved under ASX Listing Rule 7.1 and so does not reduce the Company’s capacity to issue further equity securities without stockholder approval under that rule.

The Company wishes to retain as much flexibility as possible to issue additional equity securities into the future without having to obtain stockholder approval for such issues under ASX Listing Rule 7.1. To that end, Proposal 1 seeks Stockholder approval to subsequently approve the Public Offering Common Stock under and for the purposes of ASX Listing Rule 7.4.

The Public Offering Common Stock were issued under the Company’s 15% placement capacity under ASX Listing Rule 7.1 and are therefore included in the calculation of the Company’s capacity under ASX Listing Rule 7.1.

There was no breach of ASX Listing Rule 7.1 as a result of the issue of the Public Offering Common Stock. The purpose of this proposal is to seek ratification and approval, for the purposes of ASX Listing Rule 7.4 and for all other purposes, of the issue of the Public Offering Common Stock.

Effect of Proposal 1

If Proposal 1 is passed, the Public Offering Common Stock will not count towards the Company’s 15% placement capacity for the purposes of ASX Listing Rule 7.1, thereby increasing the Company’s ability to issue additional equity securities without Stockholder approval.

If Proposal 1 is not passed, the Public Offering Common Stock will count towards the Company’s 15% placement capacity for the purposes of ASX Listing Rule 7.1, thereby limiting the Company’s ability to issue additional equity securities without Stockholder approval.

PROPOSAL NO. 2

APPROVAL OF THE OCTOBER 2025 PIPE FINANCING AND ISSUANCE OF SHARES OF COMMON STOCK PURSUANT TO THE COMPANY’S OCTOBER 2025 PIPE FINANCING

Background

Subscription Agreements

As previously announced, on October 24, 2025, the Company entered into subscription agreements (the “Subscription Agreements”) with certain investors (the “PIPE Investors”), pursuant to which, among other things, the PIPE Investors agreed to subscribe for and purchase from the Company, and the Company agreed to issue and sell to the PIPE Investors, an aggregate of approximately 1.52 million newly issued shares of the Common Stock for an aggregate purchase price of approximately $32.01 million, on the terms and subject to the conditions set forth therein (the “October 2025 PIPE Financing”).

Reasons for the Approval of the October 2025 PIPE Financing

Because our Common Stock is listed on the NYSE, we are subject to the NYSE’s rules and regulations. Section 312.03 of the NYSE Listed Company Manual requires stockholder approval prior to the issuance of common stock, or securities convertible into or exercisable for common stock, in any transaction or series of related transactions, subject to certain exceptions, in which (i) the common stock or securities convertible into or exercisable for common stock are issued to an Active Related Party if the number of shares of common stock to be issued, or if the number of shares of common stock into which the securities may be convertible or exercisable, exceeds the NYSE Active Related Party Cap, (ii) a Related Party has a five percent or greater interest (or Related Parties collectively have a ten percent or greater interest) in the consideration to be paid in the transaction or series of transactions, and the present potential issuance of common stock, or securities convertible into common stock, could result in an issuance that exceeds the NYSE Related Party Cap, and (iii) the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of the NYSE 20% Cap. The approval of the Company’s stockholders is required because the PIPE Investors may be deemed to be an Active Related Party and/or a Related Party under NYSE listing rules and the shares of common stock underlying the October 2025 PIPE Financing to be issued to the PIPE Investors may exceed the NYSE Thresholds.

The foregoing description of the Subscription Agreements is not complete and is qualified in its entirety by reference to the Subscription Agreements, the forms of which were filed as exhibits to our Current Report on Form 8-K filed with the SEC on October 24, 2025.

ASX Listing Rule Requirements

ASX Listing Rule 10.11 provides that unless one of the exceptions in ASX Listing Rule 10.12 applies, the Company must not issue or agree to issue equity securities to:

 

•

10.11.1 a related party;

 

•

10.11.2 a person who is, or was at any time in the 6 months before the issue or agreement, a substantial (30%+) holder;

 

•

10.11.3 a person who is, or was at any time in the 6 months before the issue or agreement, a substantial (10%+) holder and who has nominated a director to the board pursuant to a relevant agreement which gives them a right or expectation to do so;

 

•

10.11.4 an associate of a person referred to in ASX Listing Rule 10.11.1 to 10.11.3; or

 

•

10.11.5 a person whose relationship with the person referred to in ASX Listing Rules 10.11.1 to 10.11.4 is such that, in ASX’s opinion, the issue or agreement should be approved by Stockholders,

unless it obtains the approval of Stockholders.

By virtue of being a substantial (10%+) Stockholder of the Company and nominating two directors to the Board, Mr. Bryan Sheffield’s participation in the October 2025 PIPE Financing falls within ASX Listing Rule 10.11.3 and does not fall within any of the exceptions in ASX Listing Rule 10.12, therefore requiring approval of Stockholders under ASX Listing Rule 10.11

Directors of the Company, Mr. Scott Sheffield, Mr. Richard Stoneburner, Mr. Ryan Dalton, Mr. Phillip Pace, Mr. Fredrick Barrett, Mr. Jeffrey Bellman and Mr. David Siegel’s participation in the October 2025 PIPE Financing falls within ASX Listing Rule 10.11.1 and does not fall within any of the exceptions in ASX Listing Rule 10.12, therefore requiring the approval of Stockholders under ASX Listing Rule 10.11.

By virtue of being the son of Mr. David Siegel, Mr. Robert Siegel’s participation in the October 2025 PIPE Financing falls within ASX Listing Rule 10.11.1 and does not fall within any of the exceptions in ASX Listing Rule 10.12, therefore requiring the approval of Stockholders under ASX Listing Rule 10.11.

By virtue of being the son of Mr. Andrew Robb, Mr. Tom Robb’s participation in the October 2025 PIPE Financing falls within ASX Listing Rule 10.11.1 and does not fall within any of the exceptions in ASX Listing Rule 10.12, therefore requiring the approval of Stockholders under ASX Listing Rule 10.11.

By virtue of being the spouse of Mr. Richard Stoneburner, Ms. Sarah Pacheco’s participation in the October 2025 PIPE Financing falls within ASX Listing Rule 10.11.1 and does not fall within any of the exceptions in ASX Listing Rule 10.12, therefore requiring the approval of Stockholders under ASX Listing Rule 10.11.

Proposals 3 to 13 seek the required Stockholder approval for the issue the Related Party Common Stock pursuant to the October 2025 PIPE Financing for the purposes of ASX Listing Rule 10.11 and for all other purposes.

Effect of Proposals 3 to 13

If Proposals 3 to 13 are passed, the Company will be able to proceed with the issue of the Related Party Common Stock pursuant to the October 2025 PIPE Financing to each of the PIPE Related Parties. As approval pursuant to ASX Listing Rule 7.1 is not required for the issue of the Related Party Common Stock pursuant to the October 2025 PIPE Financing (because approval is being obtained under ASX Listing Rule 10.11), the issue of the Related Party Common Stock will not use up any of the Company’s 15% placement capacity under ASX Listing Rule 7.1.

If Proposals 3 to 13 are not passed, the Company will not be able to proceed with the issue of the Related Party Common Stock pursuant to the October 2025 PIPE Financing to each of Mr. Bryan Sheffield, Mr. Scott Sheffield, Mr. Richard Stoneburner, Mr. Ryan Dalton, Mr. Phillip Pace, Mr. Fredrick Barrett, Mr. Jeffrey Bellman, Mr. David Siegel, Mr. Robert Siegel, Mr. Tom Robb and Ms. Sarah Pacheco. In these circumstances, the Company will be unable to raise the funds that would have been raised through the issue of these securities.

(a)	the Related Party Common Stock will be issued to:

“FOR” votes from the holders of a majority of the shares of the Company’s common stock present in person or represented by proxy and entitled to vote on the matter at the Special Meeting are required to approve the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL, FOR PURPOSES OF ASX LISTING RULE 10.11 AND FOR ALL OTHER PURPOSES, OF THE ISSUE OF SHARES OF COMMON STOCK TO BRYAN SHEFFIELD, SCOTT SHEFFIELD, RICHARD STONEBURNER, RYAN DALTON, PHILLIP PACE, FREDRICK BARRETT, JEFFREY BELLMAN, DAVID SIEGEL, ROBERT SIEGEL, TOM ROBB AND SARAH PACHECO UNDER THE OCTOBER 2025 PIPE FINANCING.

PROPOSAL NO. 14

APPROVAL, FOR PURPOSES OF ASX LISTING RULE 7.1 AND FOR ALL OTHER PURPOSES, OF THE ISSUE OF 1,105,415 SHARES OF COMMON STOCK TO PIPE INVESTORS UNDER THE OCTOBER 2025 PIPE FINANCING

Background

As part of the October 2025 PIPE Financing, Proposal 14 seeks the approval of Stockholders to grant the issue of 1,105,415 shares of Common Stock to certain non-affiliated institutional investors with whom the Company had a pre-existing relationship (the “October PIPE Investors”) under the October 2025 PIPE Financing (“October PIPE Common Stock”).

ASX Listing Rule Requirements

Broadly speaking, and subject to a number of exceptions, ASX Listing Rule 7.1 limits the number of equity securities that a listed entity can issue without the approval of its stockholders over any 12-month period to 15% of the number of fully paid ordinary shares it had on issue at the start of that period.

The proposed issue of October PIPE Common Stock under Proposal 14 is conditional on the Company obtaining Stockholder approval and therefore falls within exception 17 of ASX Listing Rule 7.2 (being an agreement to issue equity securities that is conditional on the holders of the entity’s ordinary securities approving the issue under ASX Listing Rule 7.1 before the issue is made). The issue of the October PIPE Common Stock requires the approval of the Stockholders under ASX Listing Rule 7.1 because the maximum number of shares of Common Stock to be issued will exceed the 15% limit in ASX Listing Rule 7.1. Accordingly, the Company is seeking Stockholder approval under and for the purposes of ASX Listing Rule 7.1 for the issue of the October PIPE Common Stock.

The purpose of Proposal 14 is to seek Stockholder approval for the issue of 1,105,415 shares of Common Stock to the October PIPE Investors under the October 2025 PIPE Financing for the purposes of ASX Listing Rule 7.1 and for all other purposes.

Effect of Proposal 14

If Proposal 14 is passed, the Company will be able to proceed with the issue of the shares of the October PIPE Common Stock. In addition, the issue of the shares of the October PIPE Common Stock will be excluded from the calculation of the number of securities that the Company can issue without Stockholder approval under ASX Listing Rules 7.1.

If Proposal 14 is not passed, the Company will not be able to proceed with the issue of October PIPE Common Stock.

Information Required under ASX Listing Rule 7.3

The following information is provided pursuant to the requirements of ASX Listing Rule 7.3:

 

(a)	the October PIPE Common Stock are being issued under the October 2025 PIPE Financing to:

 

1.

non-affiliated investors who are institutional, professional and sophisticated investors comprising existing stockholders and new institutional, professional and sophisticated investors identified by the Company. The October PIPE Investors were already known to the Company; and

 

2.

certain members of management of the Company.

 

(b)	1,105,415 shares of Common Stock will be issued to the October PIPE Investors under the October 2025 PIPE Financing;

(c)	the shares of October PIPE Common Stock issued will be fully paid shares of Common Stock, issued on the same terms and conditions as existing shares of Common Stock;

 

(d)	the shares of October PIPE Common Stock will be issued no later than 3 months after the date of the Special Meeting;

 

(e)	the shares of October PIPE Common Stock will be issued at an issue price of US$21.00 per share of Common Stock, which will raise approximately US$23.21 million;

 

(f)	the purpose of the issue of the October PIPE Common Stock is for the Company to raise funds to support Tamboran’s development plan, working capital and other general corporate purposes;

 

(g)	the October PIPE Common Stock will be issued pursuant to the Subscription Agreements on the material terms summarized in Proposal 2 and otherwise on standard terms for placements of such kind;

 

(h)	the Shares of October PIPE Common Stock are not being issued under or to fund a reverse takeover; and

 

(i)	a voting exclusion statement applies to Proposal 14 and is included above.

Vote Required

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL, FOR PURPOSES OF ASX LISTING RULE 7.1 AND FOR ALL OTHER PURPOSES, OF THE ISSUE OF 1,105,415 SHARES OF COMMON STOCK TO THE OCTOBER PIPE INVESTORS UNDER THE OCTOBER 2025 PIPE FINANCING.

PROPOSAL 15

APPROVAL OF THE ISSUANCE OF SHARES OF COMMON STOCK TO CERTAIN DIRECTORS, OFFICERS, AND EMPLOYEES OF THE COMPANY PURSUANT TO THE COMPANY’S OCTOBER 2025 PIPE FINANCING

Background

On October 24, 2025, the Company entered into subscription agreements with certain directors, officers, and employees of the Company (the “TBN PIPE Investors”), pursuant to which, among other things, the TBN PIPE Investors agreed to subscribe for and purchase from the Company, and the Company agreed to issue and sell to the TBN PIPE Investors, an aggregate of 349,459 newly issued shares of common stock (the “TBN Shares”) at a price per share of $21.00 per share.

Reasons for the Approval of the sale of the TBN Shares to the TBN PIPE Investors

The issuance of the TBN Shares to the TBN PIPE Investors in the October 2025 PIPE Financing at a discount, offered outside the Company’s 2024 Incentive Award Plan, may be considered an “equity-compensation plan” under Section 303A.08 of the NYSE Listed Company Manual. The Company has in addition, as set out above, sought approval from stockholders in respect of the ASX Listing Rules in respect of Proposals 3 to 13 under ASX Listing Rule 10.11.

The purpose of the issue of the TBN Shares is to raise funds to progress Tamboran’s development plan in the Beetaloo Basin to reach first production and general working capital.

If our stockholders do not approve this Proposal 15, the TBN Shares will not be sold to the TBN PIPE Investors.

Material U.S. Federal Income Tax Consequences

The following is a general summary under current law of the principal United States federal income tax consequences related to TBN PIPE Investors’ participation in the October 2025 PIPE Financing. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some kinds of taxes, such as state, local and foreign income taxes and federal employment taxes, are not discussed. This summary is not intended as tax advice to the TBN PIPE Investors or any other individual, each of whom should consult his or her own tax advisors.

Generally, TBN PIPE Investors who are United States taxpayers should recognize ordinary income at the time of purchase of the TBN Shares in an amount equal to the fair market value of the shares acquired on the date of purchase, less the purchase price paid for the shares. For TBN PIPE Investors who are United States taxpayers, the TBN PIPE Investors’ basis in the TBN Shares for purposes of determining gain or loss on a subsequent sale or disposition of such shares generally will be the fair market value of the common stock on the date such TBN Shares are purchased. Any subsequent gain or loss for such TBN PIPE Investors will be taxable as a long-term or short-term capital gain or loss. We or our subsidiaries or affiliates generally should be entitled to a federal income tax deduction at the time and for the same amount as the TBN PIPE Investor recognizes ordinary income.
