Summary

Tamboran Resources closed its acquisition of Falcon Oil & Gas's international subsidiaries on May 28, 2026, paying a mix of 6.5 million shares and $23.7 million cash. The deal brings Tamboran nearly all of Falcon Australia plus exploration assets in Hungary, Ireland, and South Africa. The stock consideration represents meaningful dilution for existing shareholders, while the cash outlay reduces near-term liquidity.

The transaction includes an unusual complication: a Falcon shareholder subject to sanctions was deemed to have dissented, and Tamboran must deposit consideration into a blocked U.S. account. If those funds go unclaimed, they're permanently lost to the company—they won't revert to Tamboran's balance sheet. This creates a small but real risk of capital leakage with no recovery mechanism.

Retail holders should watch for the amended 8-K due within 71 days, which will include audited financials for the acquired businesses and pro forma statements showing the combined entity's financial position. That filing will clarify the assets acquired, any liabilities assumed, and the deal's impact on Tamboran's earnings profile.

Added in current filing · verify on EDGAR →

Effective as of the Effective Time, the Stock Consideration was issued in reliance upon Section 3(a) (10) of the Securities Act of 1933, as amended (the “Securities Act”), which exempts from the registration requirements under the Securities Act any securities that are issued in exchange for one or more bona fide outstanding securities where the terms and conditions of such issuance and exchange are approved, after a hearing upon the fairness of such terms and conditions at which all persons to whom it is proposed to issue securities in such exchange shall have the right to appear, by any court expressly authorized by law to grant such approval.

Tamboran issued stock as consideration in an exchange transaction without SEC registration, using a court-approved exemption under Section 3(a)(10) of the Securities Act. This exemption applies when a court holds a fairness hearing and approves the exchange terms. The filing references an Introductory Note (not included in this excerpt) that would contain details about the specific transaction, number of shares, and parties involved.

On May 28, 2026, Tamboran issued a press release announcing the completion of the transactions contemplated by the Arrangement Agreement.

Tamboran disclosed that it has completed transactions under an Arrangement Agreement.

Added Court approval of Arrangement with sanctioned shareholder provisions high

Added in current filing · verify on EDGAR →

on April 14, 2026, the Supreme Court of British Columbia (the “Court”) issued and entered a final order (the “Final Order”) approving the Plan of Arrangement, subject to certain amendments thereto, following a hearing by the Court which considered, among other things, the fairness of the Arrangement to certain Falcon shareholders subject to sanctions (referred to herein as the “Subject Shareholder”).

The Supreme Court of British Columbia issued a final order on April 14, 2026 approving the Plan of Arrangement between Tamboran and Falcon, with special amendments addressing a Falcon shareholder subject to sanctions. The Court specifically considered the fairness of the arrangement to this sanctioned shareholder.

Added Deemed dissent and payment terms for sanctioned shareholder medium

Added in current filing · verify on EDGAR →

Pursuant to the Final Order, the Subject Shareholder was deemed to have exercised its right to dissent in respect of the special resolution of Falcon’s shareholders approving the Arrangement and, as a result, the Final Order directs that the Subject Shareholder is entitled to receive the greater of (i) the Cash Consideration or (ii) the fair value of the Subject Shareholder’s shares in Falcon as determined by the Court in accordance with Section 245 of the Business Corporations Act (British Columbia) (the “Excess Payment”).

The sanctioned shareholder was deemed to have dissented from the Arrangement and is entitled to receive either the standard Cash Consideration or a court-determined fair value (whichever is greater). This creates potential additional payment obligations for Tamboran beyond the standard merger consideration if the court determines fair value exceeds the Cash Consideration.

Added Payment into blocked account with no reversion rights medium

Added in current filing · verify on EDGAR →

The Final Order requires that the Cash Consideration and, to the extent required, the Excess Payment, be remitted by Tamboran directly into an existing blocked account at a U.S. financial institution in the name of the Subject Shareholder, in accordance with applicable sanctions laws. Pursuant to the Final Order, to the extent any portion of the Cash Consideration or the Excess Payment, as applicable, remains unclaimed by the Subject Shareholder, neither the Cash Consideration nor the Excess Payment, as applicable, will revert to Tamboran.

Tamboran must pay the consideration into a blocked U.S. account to comply with sanctions laws. Critically, if the sanctioned shareholder never claims the funds, Tamboran cannot recover them — the money is permanently lost to the company rather than reverting back.

Event · Item 9.01 — Financial Statements and Exhibits

Tamboran disclosed completion of acquisition under arrangement agreement with Falcon Oil & Gas, with financial statements to follow within 71 days.

As permitted by Item 9.01(a) (3) of Form 8-K, any financial statements required by this Item will be filed by amendment to this Report within 71 days following the date on which this Report is required to be filed.

Tamboran is using the permitted 71-day extension to file financial statements for a business acquisition. This indicates an acquisition has closed, referencing the previously disclosed arrangement agreement with Falcon Oil & Gas Ltd. The company will provide audited financials and pro forma information in a subsequent amendment.

Added Arrangement agreement reference medium

Added in current filing · verify on EDGAR →

Arrangement Agreement, dated as of September 30, 2025, by and among Tamboran Resources Corporation, Tamboran (Beetaloo) Pty Ltd, Tamboran Resources Investments Holding Corporation and Falcon Oil & Gas Ltd.

The filing references the original arrangement agreement from September 2025 and an amending agreement from March 2026 with Falcon Oil & Gas. This suggests the transaction structure has been modified since initial announcement and has now reached a milestone requiring 8-K disclosure.
