Item 1.01

Entry into a Material Definitive Agreement

On July 31, 2026, Barnwell Hawaiian Properties, Inc., a Delaware corporation (“BHP”) and a subsidiary of Barnwell Industries, Inc.

(the “Company”), together with Ka’upulehu Developments, a Hawaii general partnership (“KD”) for which BHP serves as authorized general partner, entered into a Purchase and Sale Agreement (the “Purchase Agreement”) with David Johnston, as purchaser

(the “Buyer”). BHP and KD are each severally, and not jointly, sellers under the Purchase Agreement (together, the “Sellers”).

Under the Purchase Agreement, the Sellers will sell to the Buyer at closing (i) BHP’s 34.45% limited partner interest in KKM Makai,

LLLP, a Delaware limited liability limited partnership, and BHP’s 75% general partner interest in KD Kona 2013 LLLP, a Delaware limited liability limited partnership (together, the “Partner Interests”); (ii) KD’s rights in KD Acquisition II, LLLP

and Increment 2 of Lot 4-A at Ka’upulehu on the Island of Hawaii under a Retained Rights Agreement dated March 7, 2019 (the “KD Project Rights”); and (iii) KD’s rights under an Agreement to Terminate Project Rights dated November 17, 2025 between

the Buyer and KD. Each of KKM Makai, LLLP and KD Kona 2013 LLLP indirectly holds partner interests in the entities that lease Increments 1 and 2 of Lot 4-A from Kamehameha Schools.

The purchase price is $1,770,000 in cash, payable at closing, allocated $770,000 to the Partner Interests and $1,000,000 to the KD

Project Rights and the rights under the Agreement to Terminate. After giving effect to the minority interest held by Cambridge Hawaii LP in KD, net consideration to the Company is estimated at approximately $1.5 million. In addition, a pre-closing

distribution by Ka’upulehu Makai, LLLP of $500,000 to its partners is expected to result in a further distribution of approximately $0.1 million to the Company.

The closing of the transactions contemplated by the Purchase Agreement is to occur on or before September 15, 2026, or on a

mutually agreed date within five business days thereafter. Closing is subject to customary conditions, including, among others: (i) the accuracy in all material respects of the parties’ representations and warranties and the absence of any

material breach of any other material obligation or covenant; (ii) the absence of any pending or threatened proceeding that would restrain, enjoin, prohibit or prevent consummation of the transactions or cause them to be rescinded following

consummation; (iii) a $500,000 distribution by Ka’upulehu Makai, LLLP to its partners; and (iv) the absence of a material adverse change in the condition, operations, business or assets of KKM Makai, LLLP or KD Kona 2013 LLLP (excluding changes

arising from general economic or political conditions or changes in financial, banking or securities markets generally). The Buyer represents that it has completed its due diligence.

The Purchase Agreement may be terminated prior to closing: (i) by either party if any condition precedent to that party’s obligation

to close has not been satisfied or waived by the closing date despite good-faith efforts by the obligated party to satisfy the same; or (ii) by either party if the closing has not occurred within five business days after the closing date; provided

that a party whose material breach caused the failure to close may not terminate.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to

the full text of the Purchase Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Buyer, David Johnston, is the son of Terry Johnston, a partner in KD. In addition, the Company understands that a historical

arrangement may exist under which Terry Johnston is entitled to a commission equal to 8% of distributions from KD, although no copy of such arrangement has been located. Under the Purchase Agreement, the Buyer has agreed to indemnify the Sellers

and their affiliates against any claim by Terry Johnston (or any affiliate of his) that he is entitled to a commission on any portion of the purchase price payable to the Sellers.

The Partner Interests are being sold on a strictly “AS-IS” basis. The Sellers’ representations and warranties are limited and

survive for six months after closing. Each Seller’s aggregate liability is capped at 10% of the portion of the purchase price allocated to the assets it sold, subject to a $25,000 aggregate claim threshold, and consequential, special, incidental,

exemplary and punitive damages and lost profits are excluded. These limitations do not apply to actual common-law fraud by the applicable Seller. The Buyer will indemnify the Sellers and their affiliates from and after closing against liabilities

arising out of or relating to the Partner Interests, the KD Project Rights, the Agreement to Terminate, KKM Makai, LLLP or KD Kona 2013 LLLP, whether arising before, on or after closing. The Purchase Agreement is governed by Hawaii law.

Upon the closing, the Company expects that the transaction will achieve a complete exit from all of the Company’s known remaining

Hawaii real-estate-related interests, subject to minimal, administrative winding up activities. The Company will continue to own BHP and Barnwell Kona Corporation, both Delaware corporations, following the closing and expects to wind up those

entities thereafter. There can be no assurance that the closing will occur on the anticipated timeline or at all.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform

Act of 1995, including statements regarding the anticipated closing of the transactions described herein, expected proceeds, estimated tax liabilities, and the Company’s plans to exit its Hawaii interests and wind up certain subsidiaries. These

forward-looking statements are based on the Company’s current expectations and are subject to risks and uncertainties that could cause actual results to differ materially, including, without limitation, the failure to satisfy conditions precedent

to closing, changes in tax laws or assessments, and other risks described in the Company’s filings with the Securities and Exchange Commission. The Company undertakes no obligation to update any forward-looking statement, whether as a result of new

information, future events, or otherwise, except as required by law.

Limitations.

(a) NO OTHER REPRESENTATIONS. EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN SECTION 7 OF THIS AGREEMENT, (i) NEITHER SELLER NOR ANYONE ACTING FOR OR ON BEHALF OF SELLER HAS MADE ANY REPRESENTATION, WARRANTY, PROMISE OR

STATEMENT, EXPRESS OR IMPLIED, TO BUYER, OR TO ANYONE ACTING FOR OR ON BEHALF OF BUYER, CONCERNING THE PARTNER’S INTERESTS AND (ii) BUYER IS PURCHASING THE PARTNER INTERESTS AND EACH OF THEM IN STRICTLY “AS-IS” CONDITION.

The limitations in this Section 9 apply to this Agreement and to each assignment or other document delivered at Closing, and no such document expands any

(c) Survival; Claims. The representations and warranties of each Seller and Buyer shall survive for six (6) months after Closing, and no claim may be brought unless Buyer gives that Seller reasonably detailed

written notice of the claim before expiration of that period. All covenants to be performed at or before Closing terminate at Closing, and covenants expressly to be performed after Closing survive only in accordance with their terms.

exceed $25,000; (iv) no Seller shall be liable for consequential, special, incidental, exemplary or punitive damages or lost profits; and (v) Buyer’s sole and exclusive remedy against a Seller is a claim for damages under this Agreement, subject to

From and after Closing, Buyer shall assume, pay, perform and discharge, and shall indemnify, defend and

hold harmless each Seller and its direct and indirect partners, shareholders, members, managers, officers, directors, affiliates, employees, representatives and agents from and against all liabilities, losses, claims, damages, costs and expenses

(including reasonable attorneys’ fees) arising out of or relating to: (a) the Partner Interests, the KD Project Rights or the Agreement to Terminate (including any claim by Terry Johnston (or his affiliate) that he is entitled to a commission on

the Purchase Price, or any portion thereof, payable to Seller under this Agreement), KKM Makai or KD Kona, whether arising before, on or after Closing; (b) Buyer’s ownership, control or operation of any Purchased Asset; (c) any obligation of a

limited or general partner under any partnership agreement or applicable law, including any liability asserted against BHP by reason of its former status as general partner of KD Kona; (d) Buyer’s failure to obtain or maintain any consent,

admission, withdrawal, amendment, notice, filing or release contemplated by this Agreement; or (e) any breach by Buyer of this Agreement or a Closing document. This Section shall not apply to the extent a final, nonappealable judgment determines

that the applicable loss resulted solely from the indemnified Seller’s actual common-law fraud or breach of an express representation in Section 7. Buyer shall not settle any claim in a manner that imposes liability, an admission or non-monetary

relief on an indemnified person without that person’s prior written consent.

11.

Seller may terminate this Agreement by written notice to the other party; provided, however, that a party whose material breach of this Agreement caused the failure of the Closing to occur shall not have the right to terminate pursuant to this

Section.

Exhibit 99.1

Barnwell Industries Advances Strategic Transformation Through Sale of Remaining Hawaii Development Interests

Transaction Advances Portfolio Simplification, Strengthens Balance Sheet and Enhances Strategic Flexibility

HOUSTON, TX / ACCESS Newswire / August 4, 2026 /Barnwell Industries, Inc. (NYSE American:BRN) today announced that it has

entered into a definitive agreement to sell its remaining Hawaii development interests and related project rights. The transaction represents another important step in Barnwell’s strategy to simplify its portfolio, strengthen its balance sheet

and redeploy capital toward higher-return opportunities.

Barnwell expects to receive approximately $1.5 million in net cash proceeds from the sale, based on a gross purchase price of $1.77 million, as well as an additional pre-closing distribution of approximately $0.1

million. The transaction is subject to customary closing conditions and is expected to close before the end of the Company’s fiscal year on September 30, 2026.

The definitive agreement provides for the sale of Barnwell’s indirect partnership interests in KKM Makai, LLLP and KD Kona 2013 LLLP, which hold interests in the leases covering the Increment 1 and Increment 2 areas of

Lot 4-A at Ka‘upulehu on the Island of Hawaii. The transaction also includes development rights held by Ka‘upulehu Developments (the “Partnership”) in the Increment 2 area. Barnwell expects the limited remaining activities relating to the winding

up of the Partnership and its affairs to be completed promptly and at minimal additional cost, likely allowing the Company to complete its exit from Hawaii also by the end of fiscal 2026.

“The Board believes capital should be allocated where it can earn the highest long-term risk-adjusted returns,” said Philip Patman, Jr., Chief Financial Officer and a member of Barnwell’s Board of Directors. “This

transaction reflects that philosophy by monetizing a legacy asset whose value we believe is better realized through a sale than continued ownership. We will continue evaluating our portfolio with the same disciplined approach, monetizing assets

where appropriate and redeploying capital into higher-return opportunities. Our priorities remain disciplined capital allocation, strategic investments and acquisitions, balance-sheet strength and, where appropriate, returning capital to

shareholders.”

“In addition to generating immediate cash proceeds and an additional distribution, this transaction reduces future capital commitments, further simplifies our business and increases our flexibility to redeploy capital

into higher-return opportunities,” Patman continued. “Our objective is straightforward: to allocate capital with discipline, improve the quality of our asset base, and create long-term shareholder value.”

The Company continues to simplify its portfolio and evaluate strategic opportunities, including potential business combinations with private operating companies that could benefit from its public-company platform. The

Board will pursue only those opportunities it believes offer compelling long-term value creation for its shareholders. There can be no assurance that this review will result in a transaction.

About Barnwell Industries, Inc.

Barnwell Industries, Inc. is a diversified company with operations and interests in energy and related assets. The Company is focused on disciplined capital allocation, operational improvement, strategic repositioning,

and maximizing shareholder value.
