Amendment No. 3 is filed by (i) Bryan Sheffield, (ii) Sheffield Holdings, LP, a Texas limited partnership ("Sheffield Holdings"), (iii) Spraberry Interests, LLC, a Delaware limited liability company ("Spraberry"), (iv) Daly Waters Energy, LP, a Delaware limited partnership ("Daly Waters"), (v) Formentera Australia Fund I GP, LP, a Delaware limited partnership ("Formentera Australia"), and (vi) Formentera Investments LLC, a Delaware limited liability company ("Formentera Investments"),  (each, a "Reporting Person" and, collectively, the "Reporting Persons"), relating to the shares of the common stock, par value $0.001 per share (the "Common Stock"), of Tamboran Resources Corporation, a Delaware corporation (the "Issuer"). Capitalized terms used herein and not otherwise defined in this Amendment No. 3 have the meanings set forth in the Schedule 13D. The purpose of this Amendment No. 3 is to disclose the recent development described in Item 4 of this Amendment No. 3.

**Item 4. Purpose of Transaction**

Item 4 is hereby amended to add the following:

On July 27, 2025, the Reporting Persons entered into a Cooperation Agreement (the "Agreement") with the Issuer.

In connection with the Agreement, the Issuer agreed, among other things, to appoint (i) Scott D. Sheffield as a Class II director to the Board of Directors of the Issuer (the "Board"), effective immediately, with a term expiring at the Issuer's 2025 annual meeting of stockholders (the "2025 Annual Meeting") and (ii) Phillip Z. Pace as a Class III director to the board, effective immediately with a term expiring at the Issuer's 2026 annual meeting of stockholders (the "2026 Annual Meeting"). The Issuer also agreed to nominate and recommend Scott D. Sheffield for election to the Board at the 2025 Annual Meeting.

In connection with the Agreement, the Reporting Persons agreed to abide by certain customary standstill restrictions that will remain effective from July 27, 2025 until the earlier of (i) the Issuer's 2028 annual meeting of stockholders (the "2028 Annual Meeting") and (ii) December 31, 2028, unless earlier expired in accordance with the terms of the Agreement (the "Restricted Period"). Among the conditions that would cause the Restricted Period to terminate earlier would be (a) the Issuer's failure to renominate and recommend Mr. Pace for re-election to the Board at the 2026 Annual Meeting if Mr. Pace is available and willing to stand for re-election at that meeting and (b) the Issuer's failure to renominate and recommend Scott D. Sheffield for re-election to the Board at the 2028 Annual Meeting if Scott D. Sheffield is available and willing to stand for election at that meeting.

During the Restricted Period the Reporting Persons have agreed to cause all Voting Securities (as defined in the Agreement) that are beneficially owned by the Sheffield Group to be (a) present for quorum purposes and (b) voted or consented (i) in favor of the electon of each person nominated by the Board for election as a director, (ii) against any stockholder nominations for directors that are not approved and recommended by the Board for election, (iii) against any proposals or resolutions to remove any member of the Board and (iv) in accordance with the recommendation of the Board on all other proposals or business that may be the subject of stockholder action at such meeting; provided, however, that each member of the Sheffield Group shall be permitted to vote in its sole discretion on any proposal with respect to an Extraordinary Transaction (as defined in the Agreement).

The foregoing summary of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is attached as Exhibit 99.1 and is incorporated herein by reference.
