A forward-looking statement is one which is based on current expectations of future events or conditions and does not relate to historical or current facts. These statements include various estimates, forecasts, projections of Barnwell Industries, Inc.'s (referred to herein together with its majority-owned subsidiaries as "Barnwell," "we," "our," "us" or the "Company") future performance, statements of Barnwell's plans and objectives and other similar statements.

Investors should not place undue reliance on these forward-looking statements, as they speak only as of the date of filing of this Form 10-K, and Barnwell expressly disclaims any obligation or undertaking to publicly release any updates or revisions to any forward-looking statements contained herein.*

*Among the important factors that could cause actual results to differ materially from those in the forward-looking statements are domestic and international general economic conditions, such as recessionary trends and inflation; domestic and international political, legislative, economic, regulatory and legal actions, including changes in the policies of the Organization of the Petroleum Exporting Countries or other developments involving or affecting oil and natural gas producing countries; military conflict, embargoes, internal instability or actions or reactions of the governments of the U.S. and/or Canada in anticipation of or in response to such developments; interest costs, restrictions on production, restrictions on imports and exports in both the U.S. and Canada, the maintenance of specified reserves, tax increases and retroactive tax claims, royalty increases, expropriation of property, cancellation of contract rights, environmental protection controls, environmental compliance requirements and laws pertaining to workers' health and safety; the condition of Hawaii's real estate market, including the level of real estate activity and prices, the demand for new housing and second homes on the island of Hawaii, the rate of increase in the cost of building materials and labor, the introduction of building code modifications, changes to zoning laws, the condition of Hawaii's tourism industry and the level of confidence in Hawaii's economy; levels of land development activity in Hawaii; the potential liability resulting from pending or future litigation; the Company's acquisition or disposition of assets; the effects of changed accounting rules under GAAP promulgated by rule-setting bodies; and the factors set forth under the heading "Risk Factors" in this Form 10-K, in other portions of this Form 10-K, in the Notes to Consolidated Financial Statements, and in other documents filed by Barnwell with the SEC.

**PART I**

**ITEM 1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; BUSINESS**

**Overview**

Barnwell was incorporated in Delaware in 1956 and fiscal 2025 represented Barnwell's 69th year of operations. Barnwell operates in the following two principal business segments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Oil and Natural Gas Segment* - Barnwell engages in oil and natural gas development, production, acquisitions and sales in Canada and in the U.S.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Land Investment Segment* - Barnwell owns land interests in the State of Hawaii.

**Discontinued Operations**

On March 14, 2025, the Company entered into and completed the sale of its wholly-owned subsidiary, Water Resources International, Inc. ("Water Resources"). Water Resources drills water wells and installs and repairs water pumping systems in the State of Hawaii and represented Barnwell's contract drilling segment. As a result of the sale, the Company has classified the related assets, liabilities and the results of its contract drilling business as discontinued operations in the consolidated financial statements for all periods presented. Prior to the sale, the Company did not have any assurances that a sale of Water Resources was likely to occur. Unless otherwise noted, the discussions throughout Part I of this Form 10-K pertains only to Barnwell's continuing operations. For information on discontinued operations, refer to Note 3 "Discontinued Operations" in the Notes to Consolidated Financial Statements in Item 8 of this report.

**Oil and Natural Gas Segment**

*Overview*

Barnwell acquires and develops crude oil and natural gas assets in the province of Alberta, Canada via two corporate entities, Barnwell of Canada, Limited and Octavian Oil Limited. Barnwell of Canada is a U.S. incorporated company that has been active in Canada for over 50 years, primarily as a non-operator participating in exploration projects operated by others. Octavian Oil is a Canadian company incorporated in 2016 to achieve growth through the acquisition and development of crude oil reserves in the field of Twining, Alberta. Additionally, through its wholly-owned subsidiaries BOK Drilling, LLC ("BOK"), established in February 2021, and Barnwell Texas, LLC ("Barnwell Texas"), established in November 2022, Barnwell was, until August 8, 2025, involved in oil and natural gas investments in Oklahoma and Texas, respectively.

*Strategy*

The Twining field, in Alberta, Canada represents 86% of Barnwell's fiscal 2025 production. These assets were acquired in August 2018 and subsequently expanded through smaller acquisitions of various partner interests. These assets are partially operated by the Company and partially operated by Pine Cliff Energy Ltd. The majority of Barnwell's operated oil wells have annual decline rates below 15%, which supports lower capital investment requirements to maintain production levels. This lower capital

------

requirement to maintain production, in addition to the land being largely continued with no expiries, allows Barnwell to drill opportunistically when commodity prices are favorable.

Since entering the Twining area, Barnwell has participated in drilling 12 gross (5.6 net) horizontal development wells using multi-stage sand fracturing. Of these, 3 wells are 100%-owned and operated and 9 (2.6 net) are non-operated. These wells have all either been profitable or are forecasted to be profitable, and Barnwell intends to continue development of the pool with more horizontal wells as commodity prices permit.

Barnwell also holds minor legacy assets throughout Alberta, Canada representing 3% of Barnwell's fiscal 2025 production. These non-operated oil and natural gas assets produce shallow gas or conventional oil from a varying interest in a variety of pools and have been accumulated over decades. In fiscal 2024 and 2025, Barnwell has divested many of these properties to reduce operational risk and increase strategic focus in the Twining area. Barnwell remains active in evaluating market opportunities to further divest remaining legacy assets along with acquisition opportunities to expand our production and development portfolio.

The Company had non-operated working interests in seven wells in Oklahoma ranging from 1.2% to 4.2%, along with a 0.07% overriding royalty interest in one well. Our interests in Oklahoma produced 4% of Barnwell's fiscal 2025 production. Our interests in Oklahoma were sold on August 8, 2025.

The Company had a 15.4% non-operated working interest in two wells in the Permian Basin in Texas. Our interests in Texas produced 7% of Barnwell's fiscal 2025 production. Our interests in Texas were sold on August 8, 2025.

*Operations*

Our oil and natural gas segment revenues, profitability, and future growth potential are closely tied to commodity prices and the Company's ability to fund reserves development through cashflow or external financing. In recent years, the industry has experienced volatile oil and natural gas prices, and when these prices are in low cycle they negatively impact our operating results, cash flows and liquidity. Credit and capital markets for oil and natural gas investments have been tight recently, but as capital becomes more available we may seek to raise additional capital when market conditions are favorable and aligned with our growth strategy.

Barnwell's oil and natural gas unit sales are based on production from operated and non-operated properties. In Canada, oil prices received are influenced by differentials to West Texas Intermediate ("WTI"). Historically, these differentials resulted in significant discounts due to limited export capacity and transportation bottlenecks. In 2025, improved pipeline egress contributed to more favorable realized pricing for Barnwell's Canadian oil production. Oil prices received from our Texas and Oklahoma properties were generally in line with WTI pricing.

Natural gas prices continues to show seasonal strength during the winter months, driven by increased heating demand. In Canada, gas prices are based on AECO hub benchmark prices, which typically trade at a discount to U.S. Henry Hub pricing due to regional supply dynamics and infrastructure constraints.

While our Oklahoma and Texas interests were sold in the fourth quarter of 2025, in Oklahoma, the pricing of our natural gas reflected prices close to Henry Hub pricing. In Texas, our natural gas was sold at

------

the Waha Hub, where prices were significantly discounted to Henry Hub pricing due to limited gas egress from the Permian Basin and excess supply in the area.

*Preparation of Reserve Estimates*

Barnwell's reserves are estimated by our independent petroleum reserve engineers, InSite Petroleum Consultants Ltd. ("InSite"), in accordance with generally accepted petroleum engineering and evaluation principles and techniques and rules and regulations of the SEC. All information with respect to the Company's reserves in this Form 10-K is derived from the report of InSite, which is filed with this Form 10-K as Exhibit 99.1.

The preparation of data used by the independent petroleum reserve engineers to compile our oil and natural gas reserve estimates was completed in accordance with various internal control procedures which include verification of data input into reserves evaluation software, reconciliations and reviews of data provided to the independent petroleum reserve engineers to ensure completeness, and management review controls, including an independent internal review of the final reserve report for completeness and accuracy.

Barnwell has a Reserves Committee consisting of three directors, two of which are independent directors and the third is Barnwell's Chief Executive Officer. The Reserves Committee was established to ensure the independence of the Company's petroleum reserve engineers. The Reserves Committee is responsible for reviewing the annual reserve evaluation reports prepared by the independent petroleum reserve engineering firms and ensuring that the reserves are reported fairly in a manner consistent with applicable standards. The Reserves Committee meets annually to discuss reserve issues and policies and to meet with Company personnel and the independent petroleum reserve engineers.

The President and Chief Operating Officer of Barnwell of Canada and Octavian Oil, who also serves as the President and Chief Executive Officer of Barnwell effective April 1, 2024, is a professional engineer with over 25 years of relevant experience in the oil and natural gas industry in Canada and is a member of the Association of Professional Engineers and Geoscientists of Alberta.

*Reserves*

At September 30, 2025, Barnwell's reserves were approximately 66% operated and consisted of 47% conventional oil, 12% conventional natural gas liquids, and 41% natural gas. At September 30, 2024, Barnwell's reserves were approximately 52% operated and consisted of 41% conventional oil, 15% conventional natural gas liquids, and 44% natural gas.

The amounts set forth in the following table, based on our independent reserve engineers' evaluation of our reserves, summarize our estimated proved reserves of oil, natural gas liquids, and natural gas as of September 30, 2025 for all properties located in Canada in which Barnwell has an interest. All of our oil and natural gas reserves are based on constant dollar price and cost assumptions. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established proved producing oil and natural gas properties. Accordingly, these estimates are expected to change as future information becomes available. Proved oil and natural gas reserves are the estimated quantities of oil and natural gas that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under economic and operating conditions (i.e., prices and costs) existing at the time the estimate is made. Proved developed oil and natural gas reserves are proved reserves that can be

------

expected to be recovered through existing wells and equipment in place and under operating methods being utilized at the time the estimates were made. No estimates of total proved net oil or natural gas reserves have been filed with, or included in reports to, any federal authority or agency, other than the SEC, since October 1, 2024.

---

During fiscal 2025, Barnwell's total net proved reserves of oil and natural gas liquids decreased by 339,000 Bbls (35%) and 198,000 Bbls (55%), respectively, and total net proved reserves of natural gas decreased by 3,026,000 Mcf (47%), for a combined decrease of 1,043,000 Boe (43%). The decrease in proved reserves were due to the sale of U.S. oil and natural gas interests which was completed on August 8, 2025 and amounted to 425,000 Boe. The remaining decrease in reserves were a result of production and the removal of a proved undeveloped well which was represented as 239,000 Boe in the prior year's balance due to a significant portion of the Company's capital resources being devoted to a proxy contest and consent election.

The following tables set forth Barnwell's oil and natural gas net reserves at September 30, 2025, by location and property name, based on information prepared by InSite, as well as net production and net revenues by location and property name for the year ended September 30, 2025. The reserve data in these tables are based on constant dollars where reserve estimates are based on sales prices, costs and statutory tax rates using a historical average price of the first day pricing of the last 12-months ending with September 2025.

Net proved reserves that are attributable to existing producing wells are primarily determined using decline curve analysis. Net proved reserves attributable to producing wells with limited production history and for undeveloped locations are estimated using performance from analogous wells in the surrounding area and geologic data to assess the reservoir continuity.

*Standardized Measure of Discounted Future Net Cash Flows*

The following table sets forth Barnwell's "Estimated Future Net Revenues" from total proved oil, natural gas and natural gas liquids reserves located in Canada and the present value of Barnwell's "Estimated Future Net Revenues" (discounted at 10%) as of September 30, 2025. Estimated future net revenues for total proved reserves are net of estimated future expenditures of developing and producing the proved reserves, and assume the continuation of existing economic conditions. Net revenues have been calculated using the average first-day-of-the-month price during the 12-month period ending as of the balance sheet date and current costs, after deducting all royalties, operating costs, future estimated capital expenditures (including abandonment costs), and income taxes. The amounts below include future cash flows from reserves that are currently proved undeveloped reserves and do not deduct general and administrative or interest expenses.

_______________________________________________

\*&nbsp;&nbsp;&nbsp;&nbsp; This amount does not purport to represent, nor should it be interpreted as, the fair value of Barnwell's oil and natural gas reserves. An estimate of fair value would also consider, among other items, the recovery of reserves not presently classified as proved, anticipated future changes in oil and natural gas prices (these amounts were based on a natural gas price of $1.09 per Mcf and an oil price of $60.92 per Bbl) and costs, and a discount factor more representative of the time value of money and the risks inherent in reserve estimates.

Barnwell has included all abandonment, decommissioning and reclamation costs and inactive well costs into the Company's reserve reports in accordance with best practice recommendations.

*Oil and Natural Gas Production*

The following table summarizes (a) Barnwell's net production for the last three fiscal years, based on sales of natural gas, oil and natural gas liquids, from all wells in which Barnwell has or had an interest, and (b) the average sales prices and average production costs for such production during the same periods. Production amounts reported are net of royalties. All of Barnwell's net production in fiscal 2025, 2024 and 2023 was derived in Alberta, Canada and in the U.S. states of Oklahoma and Texas. For a discussion regarding our total annual production volumes, average sales prices, and related production costs, see Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

*Capital Expenditures and Acquisitions*

Barnwell invested $939,000 in oil and natural gas properties during fiscal 2025, including accrued capital expenditures and acquisitions of oil and natural gas properties and excluding additions and revisions to estimated asset retirement obligations. Barnwell's capital expenditures were primarily related to equipment, facility upgrades and well workovers.

Barnwell invested $4,805,000 in oil and natural gas properties during fiscal 2024, including accrued capital expenditures and acquisitions of oil and natural gas properties and excluding additions and revisions to estimated asset retirement obligations. Barnwell's capital expenditures were primarily for the drilling of a new well and for equipment and upgrades to facilities, all of which were in the Twining area.

*Well Drilling Activities*

The Company did not drill or participate in the drilling of wells during the year ended September 30, 2025.

------

In fiscal 2024, the Company drilled one gross (1.0 net) operated development oil well in the Twining area which started producing in mid-September 2024. Capital expenditures incurred by the Company for this well totaled approximately $3,183,000. The Company did not drill or participate in the drilling of wells in Texas or in Oklahoma during the year ended September 30, 2024.

In fiscal 2023, the Company participated in the drilling of three gross (0.9 net) non-operated development wells in the Twining area of Alberta, Canada. Total capital expenditures for the year ended September 30, 2023 totaled approximately $4,770,000 and included the drilling, completion and equipping of the three gross (0.9 net) wells along with various upgrades to the Twining facilities. Additionally, the Company participated in the drilling of two gross (0.3 net) non-operated development oil wells in Texas. Capital expenditures incurred for the drilling of these two wells totaled approximately $4,293,00 during the year ended September 30, 2023. The Company did not drill or participate in the drilling of wells in Oklahoma during the year ended September 30, 2023.

*Producing Wells*

As of September 30, 2025, Barnwell has interests in 109 gross (62.9 net) producing wells in Alberta, Canada, of which 76 gross (58.2 net) were oil wells and 33 gross (4.7 net) were natural gas wells.

*Developed Acreage and Undeveloped Acreage*

The following table sets forth the gross and net acres of both developed and undeveloped oil and natural gas leases in the province of Alberta, Canada which Barnwell held as of September 30, 2025.

_________________________________________________

\*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "Developed Acreage" includes the acres covered by leases upon which there are one or more producing wells. "Undeveloped Acreage" includes acres covered by leases upon which there are no producing wells and which are maintained by the payment of delay rentals or the commencement of drilling thereon.

Eighty-one percent of Barnwell's undeveloped acreage is not subject to expiration at September 30, 2025. Nineteen percent of Barnwell's leasehold interests in undeveloped acreage is subject to expiration and may expire over the next five fiscal years, if not developed, as follows: 9% expire during fiscal 2026; 6% expire during fiscal 2027; 4% expire during fiscal 2028; and no expirations during fiscal 2029 and fiscal 2030. There can be no assurance that Barnwell will be successful in renewing its leasehold interests in the event of expiration.

Barnwell's undeveloped acreage includes a significant concentration in the Twining area (3,707 net acres). The remaining undeveloped acreage is at non-operated properties over which we do not have control, and the value of such acreage is not estimated to be significant at current commodity prices.

*Marketing of Oil and Natural Gas* 

Barnwell sells its Canadian oil, natural gas, and natural gas liquids production under short-term contracts between itself and two main oil purchasers, one natural gas purchaser, and one natural gas liquids purchaser. The prices received are freely negotiated between buyers and sellers and are determined from transparent posted prices adjusted for quality and transportation differentials.

------

In February 2025, the Company amended certain of its Canadian purchase and sales contracts to change the sales price on 1,055 gross Mcf per day of the Canadian natural gas it will sell during the period from April 1, 2025 to October 31, 2025 to a fixed index price before differentials of $1.95 Canadian dollars per Mcf, with remaining volumes continuing to be sold at spot prices. This per day volume of natural gas under this fixed index price contract was equivalent to approximately 38% of Canadian natural gas gross production per day for the year ended September 30, 2025. Additionally, in September 2025, the Company amended the sales price on 1,583 gross Mcf per day of the Canadian natural gas it will sell during the period from November 1, 2025 to March 31, 2026 to a fixed index price before differentials of $3.03 Canadian dollars per Mcf, with remaining volumes continuing to be sold at spot prices. This per day volume of natural gas under this fixed index price contract that will affect the period from November 1, 2025 to March 31, 2026, is equivalent to approximately 58% of Canadian natural gas gross production per day for the year ended September 30, 2025. These natural gas contracts were eligible for and elected as normal purchase and normal sales exception contracts and were thus excluded from derivative accounting.

In June 2025, the Company amended the sales price on 100 gross barrels per day of the Canadian oil that it will sell during the period from July 1, 2025 to December 31, 2025 to a fixed index price before differentials of $70.35 per net barrel, with remaining volumes continuing to be sold at spot prices. This per day volume of oil under this fixed index price was equivalent to approximately 19% of Canadian oil gross production per day for the year ended September 30, 2025. These oil contracts were eligible for and elected as normal purchase and normal sales exception contracts and were thus excluded from derivative accounting.

Subsequent to fiscal 2025, the Company amended the sales price on 1,055 gross Mcf per day of the Canadian natural gas it will sell during the period from April 1, 2026 to October 31, 2026 to a fixed index price before differentials of $2.94 Canadian dollars per Mcf, with remaining volumes continuing to be sold at spot prices. This per day volume of natural gas under this fixed index price contract that will affect the period from April 1, 2026 to October 31, 2026, is equivalent to approximately 38% of Canadian natural gas gross production per day for the year ended September 30, 2025.

In fiscal 2025 and 2024, Barnwell took most of its Canadian oil, natural gas liquids and natural gas "in kind" where Barnwell markets the products instead of having the operator of a producing property market the products on Barnwell's behalf. We sell oil, natural gas and natural gas liquids to a variety of energy marketing companies. Because our products are commodities for which there are numerous marketers, we are not dependent upon one purchaser or a small group of purchasers.

*Governmental Regulation*

The jurisdictions in which the oil and natural gas properties of Barnwell are located have regulatory provisions relating to permits for the drilling of wells, the spacing of wells, the prevention of oil and natural gas waste, allowable rates of production, environmental protection, and other matters. The amount of oil and natural gas produced is subject to control by regulatory agencies in each province. The province of Alberta and the Government of Canada also monitor the volume of natural gas that may be removed from the province and the conditions of removal; currently all our Canadian natural gas is sold within Alberta.

All of Barnwell's Canadian gross revenues were derived from properties located within Alberta, which charges oil and natural gas producers a royalty for production within the province. Provincial royalties are calculated as a percentage of revenue and vary depending on production volumes, selling

------

prices and the date of discovery. Barnwell also pays gross overriding royalties and leasehold royalties on a portion of its oil and natural gas sales to parties other than the province of Alberta.

Under the current royalty framework for newly drilled wells, the same royalty calculation applies to both oil and natural gas wells and royalties are determined on a revenue minus cost basis where producers pay a flat royalty rate of 5% of gross revenues until a well reaches payout after which an increased post-payout royalty applies. Post payout royalties vary with commodity prices and well production rates.

In fiscal 2025, 72% of total Canadian royalties were related to Alberta government charges and 28% of royalties were related to freehold, overriding royalties and other charges.

In fiscal 2025, the weighted-average royalty rate paid on all of Barnwell's Canadian natural gas was 4%, and the weighted-average royalty rate paid on oil was 16%.

Under Canadian oil and gas law and regulations, in order for the Company to retain the right to acquire, transfer, or drill well licenses, Barnwell must maintain a favorable Licensee Capability Assessment ("LCA") with the Alberta Energy Regulator ("AER"). The LCA is intended to be a comprehensive assessment of corporate health and considers a wide variety of factors and establishes guidelines for the industry with regards to the management of liabilities throughout the entire lifecycle of oil and gas projects. Factors considered by the AER are combined into six groups, these being current financial distress, liability magnitude, resources lifespan, operations compliance, closure efficiency, and administrative compliance. These factors are compared to peer operators and ranked into three "Tiers." Barnwell's assessment under the LCA Program is currently favorable with Tier 1 or Tier 2 overall rankings in the six factor groups. Barnwell believes it can continue to manage its operations to maintain a favorable ranking.

A program has also been implemented by the AER which requires mandatory annual minimum expenditures towards outstanding decommissioning and reclamation obligations in accordance with AER targets which are adjusted by the AER on an annual basis. The target for calendar 2026 is 6.5% of an individual company's inactive liability. This amount for Barnwell is approximately $237,000. Barnwell believes the targets assessed by the AER are within estimated forecasts for Barnwell's future ARO spending and therefore the Company expects to be in compliance with AER spending targets under their mandatory spend requirements.

In instances where Barnwell is a non-operating partner of a company which has become insolvent, Barnwell and any remaining partners are responsible for administering site closure. This is achieved in one of two ways. First, either Barnwell or the other partners proceed with closure, and then make a claim for the costs attributed to the insolvent entity from the Orphan Well Association ("OWA") after the abandonment work has been certified complete by the AER. Alternatively, Barnwell may pay a deposit to the OWA for its net share of the estimated closure costs, plus contingency as determined by the OWA. This allows the OWA to proceed with closure work on behalf of all partners. As of September 2025, Barnwell had provided $975,000 in cash deposits to the OWA, and $462,000 of the deposit has been spent on closure activities as at September 30, 2025. If the amount of deposit proves larger than that required by the OWA to complete the estimated work, Barnwell will receive a refund on the excess after sites are certified by the AER. These deposits do not earn interest. Asset retirement obligations of Barnwell's net share of sites operated by all partners are included in "Asset retirement obligation", current and long-term, in the Consolidated Balance Sheets.

------

Over the past nine years, the Company has worked to reduce its abandonment and reclamation obligations associated with its oil and natural gas segment, both by divesting low-productivity assets and actively closing wells and sites. Twenty-five Barnwell-operated sites have been certified as fully reclaimed or exempt since 2016.

*Competition*

Barnwell competes in the sale of oil and natural gas mainly on the ability to deliver products. The oil and natural gas industry is intensely competitive in all phases, including the acquisition and development of new production and reserves and the acquisition of equipment and labor necessary to conduct drilling activities. The competition comes from numerous major oil companies as well as numerous other independent operators. There also is competition between the oil and natural gas industry and other industries in supplying the energy and fuel requirements of industrial, commercial and individual consumers. Barnwell is a minor participant in the industry and competes in its oil and natural gas activities with many other companies having far greater financial, technical and other resources.

**Land Investment Segment**

*Overview*

Barnwell owns a 77.6% interest in Kaupulehu Developments, a Hawaii general partnership ("Kaupulehu Developments") that has the right to receive payments from KD I and KD II resulting from the sale of lots and/or residential units by KD I and KD II within the approximately 870 acres of the Kaupulehu Lot 4A area in two increments ("Increment I" and "Increment II"), located approximately six miles north of the Kona International Airport in the North Kona District of the island of Hawaii. Kaupulehu Developments also holds an interest in approximately 1,000 acres of vacant leasehold land zoned conservation located adjacent to Lot 4A under a lease that terminates in December 2025, which currently has no development potential without both a development agreement with the lessor and zoning reclassification.

&nbsp;&nbsp;&nbsp;&nbsp;Barnwell, through two limited liability limited partnerships, KD Kona and KKM Makai ("KKM"), holds a non-controlling ownership interest in the Kukio Resort Land Development Partnerships comprised of KD Kukio Resorts, KD Maniniowali, and KDK. The Kukio Resort Land Development Partnerships own certain real estate and development rights interests in the Kukio, Maniniowali and Kaupulehu portions of Kukio Resort, a private residential community on the Kona coast of the island of Hawaii, as well as Kukio Resort's real estate sales office operations. KDK holds interests in KD I and KD II. KD I is the developer of Increment I, and KD II is the developer of Increment II. Barnwell's ownership interests in the Kukio Resort Land Development Partnerships are accounted for using the equity method of accounting.

In November 2025, Kaupulehu Developments entered into an agreement with Mr. David Johnston, the son of Mr. Terry Johnston, a partner in Kaupulehu Developments, to surrender any and all remaining rights for Increment II for $2,000,000 of which $70,000 was received. Additionally, the purchaser has the right to extend the closing by up to two years by making a $70,000 payment in each of the next two years, with those payments applied against the $2,000,000 purchase price. The closing of this transaction is entirely dependent on the purchaser and therefore may not happen.

------

Subsequent to fiscal 2025, pursuant to a unit purchase agreement KDK, of which Barnwell holds a 19.6% interest, agreed to sell KDK's interests in Increment II to Mr. David Johnston for $2,109,000. The unit purchase agreement is subject to due diligence, and there is no certainty that the transaction will close. Furthermore, there is also no assurance on the timing or amounts that the general partner of KDK would distribute upon a closing.

*Operations*

Increment I is an area of 80 single-family lots, all of which were sold from 2006 to 2024, and a beach club on the portion of the property bordering the Pacific Ocean. Increment II is the remaining portion of the approximately 870-acre property and is zoned for single-family and multi-family residential units and a golf course and clubhouse. Two residential lots of approximately two to three acres in size fronting the ocean were developed within Increment II and sold by KD II, and the remaining acreage within Increment II is not yet under development. It is uncertain when or if KD II will develop the other areas of Increment II, and there is no assurance with regards to the amounts of future sales from Increment II. The remaining 420 developable acres at Increment II are entitled for up to 350 homesites. No definitive development plans have been made by KD II, the developer of Increment II, as of the date of this report.

Kaupulehu Developments was entitled to receive payments from KD I based on 10% of the gross receipts from KD I's sales of single-family residential lots in Increment I. In fiscal 2024, the last two remaining single-family lots of the 80 lots developed within Increment I were sold.

In March 2019, KD II admitted a new development partner, Replay Kaupulehu Development, LLC ("Replay"), a party unrelated to Barnwell, in an effort to move forward with development of the remainder of Increment II at Kaupulehu. KDK and Replay hold ownership interests of 55% and 45%, respectively, of KD II and Barnwell has a 10.8% indirect non-controlling ownership interest in KD II through KDK, which is accounted for using the equity method of accounting. Barnwell continues to have an indirect 19.6% non-controlling ownership interest in KD Kukio Resorts, KD Maniniowali, and KD I.

Under the terms of the Increment II agreement with KD II, Kaupulehu Developments is entitled to 15% of the distributions of KD II, the cost of which is to be solely borne by KDK out of its 55% ownership interest in KD II, plus a priority payout of 10% of KDK's cumulative net profits derived from Increment II sales subsequent to Phase 2A, up to a maximum of $3,000,000 as to the priority payout. Such interests are limited to distributions or net profits interests and Barnwell does not have any partnership interests in KD II or KDK through its interest in Kaupulehu Developments. The arrangement also gives Barnwell rights to three single-family residential lots in Phase 2A of Increment II, and four single-family residential lots in phases subsequent to Phase 2A when such lots are developed by KD II, all at no cost to Barnwell. Barnwell is committed to commence construction of improvements within 90 days of the transfer of the four lots in the phases subsequent to Phase 2A as a condition of the transfer of such lots. Also, in addition to Barnwell's existing obligations to pay professional fees to certain parties based on percentages of its gross receipts, Kaupulehu Developments is obligated to pay an amount equal to 0.72% and 0.2% of the cumulative net profits of KD II to KD Development and a pool of various individuals, respectively, all of whom are partners of KKM and are unrelated to Barnwell, in compensation for the agreement of these parties to admit the new development partner, Replay, for Increment II. Such compensation will be reflected as the obligation becomes probable and the amount of the obligation can be reasonably estimated. As stated above, Increment II is not yet under development and it is uncertain when or if KD II will develop the other areas of Increment II, and there is no assurance with regards to the amounts of future sales from Increment II.

------

In fiscal 2024, the Kukio Resort Land Development Partnerships sold the last two remaining lots in Increment I and as a result of the lot sales, made cash distributions to its partners of which Barnwell received $1,071,000 resulting in a net amount of $953,000, after distributing $118,000 to non-controlling interests.

*Competition*

Barnwell's land investment segment is subject to intense competition in all phases of its operations including the acquisition of new properties, the securing of approvals necessary for land rezoning, and the search for potential buyers of property interests presently owned. The competition comes from numerous independent land development companies and other industries involved in land investment activities. The principal factors affecting competition are the location of the project and pricing. Barnwell is a minor participant in the land development industry and competes in its land investment activities with many other entities having far greater financial and other resources.

**Financial Information About Industry Segments and Geographic Areas**

Note 11 in the "Notes to Consolidated Financial Statements" in Item 8 contains information on our segments and geographic areas.

**Employees**

At December 1, 2025, Barnwell employed 18 individuals; 16 on a full time basis and 2 on a part-time basis.

**Environmental Costs**

Barnwell is subject to extensive environmental laws and regulations. U.S. Federal and state and Canadian Federal and provincial governmental agencies issue rules and regulations and enforce laws to protect the environment which are often difficult and costly to comply with and which carry substantial penalties for failure to comply, particularly in regard to the discharge of materials into the environment. These laws, which are constantly changing, regulate the discharge of materials into the environment and maintenance of surface conditions and may require Barnwell to remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites where it has a working interest.

For further information on environmental remediation, see the Contingencies section included in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the notes to our consolidated financial statements included in Item 8, "Financial Statements and Supplementary Data."

**ITEM 1A.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RISK FACTORS**

The business of Barnwell and its subsidiaries face numerous risks, including those set forth below or those described elsewhere in this Form 10-K or in Barnwell's other filings with the SEC. The risks described below are not the only risks that Barnwell faces. If any of the following risk factors should occur, our profitability, financial condition or liquidity could be materially negatively impacted.

*Entity-Wide Risks*

**The Company faces issues that could impair our ability to continue as a going concern in the future.**

Our ability to sustain our business in the future will depend on sufficient oil and natural gas operating cash flows which are dependent on oil and natural gas prices, which can and in the past have fluctuated significantly, and on oil and natural gas operating expenses which are both variable and fixed. A sufficient level of oil and natural gas operating cash flows are necessary to fund discretionary oil and natural gas capital expenditures which must be economically successful to provide sufficient returns to grow reserves and production or at a minimum replace declining production from aging wells. Such a level of oil and natural gas capital expenditures will require funding from external debt and/or equity sources that are not currently in place, but those sources may not be feasible or sufficient. In addition, we will need sufficient cash flows to fund our non-discretionary outflows such as oil and natural gas asset retirement obligations, ongoing oil and natural gas operating expenses and general and administrative expenses, both those related to our oil and natural gas operations and those related to our being a public company.

**Continued actions by an activist shareholder have had, and may continue to have, a significant negative impact on our ability to execute our business strategies and have had, and may continue to have, an adverse affect on our results of operations and financial condition.**

In response to various actions of Mr. Ned L. Sherwood and certain affiliated shareholders (collectively, the "Sherwood Group"), the Board of Directors appointed an Executive Committee comprised of Messrs. Kinzler, Grossman and Horowitz and this Executive Committee retained the services of various professionals, including attorneys, proxy solicitors, proxy advisors, and public relations and financial advisors. We have incurred substantial legal, public relations and other advisory fees and proxy solicitation expenses, and we currently expect those costs and expenses may continue. In addition, continuing perceived uncertainties as to our future direction, strategy or leadership created as a consequence may result in the loss of potential business opportunities, harm our ability to attract new or retain existing directors and employees, disrupt relationships with the Company, and the market price of our common stock could also experience periods of increased volatility as a result.

**Stockholders may be diluted significantly through our efforts to obtain financing, satisfy obligations through the issuance of securities or use our stock as consideration in certain transactions.**

Our Board of Directors has authority, without action or vote of the stockholders, subject to the requirements of the NYSE American stock exchange and applicable law, to issue all shares of our common stock or other debt or equity instruments to purchase such shares of our common stock. In addition, we may raise capital by selling shares of our common stock, possibly at a discount to market in the future. These actions would result in dilution of the ownership interests of existing stockholders and may further dilute common stock book value, and that dilution may be material. A related effect of such

------

issuances may enhance existing large stockholders' influence on the Company, including that of Alexander Kinzler, our General Counsel and Secretary.

**A small number of stockholders, including our General Counsel and Secretary, own a significant amount of our common stock and may have influence over the Company.**

As of September 30, 2025, our General Counsel and Secretary and two other stockholders hold approximately 48% of our outstanding common stock. The interests of one or more of these stockholders may not always coincide with the interests of other stockholders. These stockholders have significant influence over all matters submitted to our stockholders, including the election of our directors, and could accelerate, delay, deter or prevent a change of control of the Company.

**Our operations are subject to currency rate fluctuations.**

Our operations are subject to fluctuations in foreign currency exchange rates between the U.S. dollar and the Canadian dollar. Our financial statements, presented in U.S. dollars, may be affected by foreign currency fluctuations through both translation risk and transaction risk. Volatility in exchange rates may adversely affect our results of operations, particularly through the weakening of the U.S. dollar relative to the Canadian dollar which may affect the relative prices at which we sell our oil and natural gas and may affect the cost of certain items required in our operations. To date, we have not entered into foreign currency hedging transactions to control or minimize these risks.

**Adverse changes in actuarial assumptions used to calculate retirement plan costs due to economic or other factors, or lower returns on plan assets could adversely affect Barnwell's results and financial condition.**

Retirement plan cash funding obligations and plan expenses and obligations are subject to a high degree of uncertainty and could increase in future years depending on numerous factors, including the performance of the financial markets, specifically the equity markets and levels of interest rates.

**Declines in the price of our common stock could adversely affect the value of an asset on our balance sheet and our stockholders' equity.** 

Currently, Barnwell's pension plan is overfunded, meaning that the current fair value of the assets held by the pension plan exceeds the estimated current accumulated benefit obligation of the pension plan. The overfunded amount is included on our balance sheet as an asset titled "Asset for retirement benefits." As of September 30, 2025, the value of that asset was $5,928,000, which represented 28% of the Company's total assets of $20,812,000 and 85% of our stockholders' equity. A decline in the value of our pension plan's investments overall, or of any one investment, could reduce the value of "Asset for retirement benefits."

A portion of the pension plan's investments is in publicly traded stocks, one of which is Barnwell's common stock. As of September 30, 2025, the value of the Barnwell common stock held by the pension plan was $866,000, representing approximately 6% of the fair market value of the pension plan's assets. A decline in the price of our common stock would also have the effect of reducing the value of our "Asset for retirement benefits," total assets and our stockholders' equity.

------

**The price of our common stock has been volatile and could continue to fluctuate substantially.**

The market price of our common stock has been volatile and could fluctuate based on a variety of factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in commodity prices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• variations in results of operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• announcements by us and our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• legislative or regulatory changes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general trends in the industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general market conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• litigation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other events applicable to our industries.

**Failure to retain key personnel could hurt our operations.**

We require highly skilled and experienced personnel to operate our business. In addition to competing in highly competitive industries, we compete in a highly competitive labor market. Our business could be adversely affected by an inability to retain personnel or upward pressure on wages as a result of the highly competitive labor market. Further, there are significant personal liability risks to Barnwell of Canada's individual officers and directors related to well clean-up costs that may affect our ability to attract or retain the necessary people.

**We are a smaller reporting company and benefit from certain reduced governance and disclosure requirements, including that our independent registered public accounting firm is not required to attest to the effectiveness of our internal control over financial reporting. We cannot be certain if the omission of reduced disclosure requirements applicable to smaller reporting companies will make our common stock less attractive to investors.**

Currently, we are a "smaller reporting company," meaning that our outstanding common stock held by nonaffiliates had a value of less than $250 million at the end of our most recently completed second fiscal quarter. As a smaller reporting company, we are not required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, meaning our auditors are not required to attest to the effectiveness of the Company's internal control over financial reporting. As a result, investors and others may be less comfortable with the effectiveness of the Company's internal controls and the risk that material weaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we take advantage of our ability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing only two years of audited financial statements in annual reports and simplified executive compensation disclosures. Consequently, it may be more challenging for investors to analyze our results of operations and financial prospects, as the information we provide to stockholders may be different from what one might receive from other public companies in which one hold shares. As a smaller reporting company, we are not required to provide this information.

*Risks Related to Oil and Natural Gas Segment*

**Acquisitions or discoveries of additional reserves are needed to increase our oil and natural gas segment operating results and cash flow.** 

In August 2018, Barnwell made a significant reinvestment into its oil and natural gas segment with the acquisition of the Twining property in Alberta, Canada. The Company believes there are potential undeveloped reserves for which significant future capital expenditures will be needed to convert those potential undeveloped reserves into developed reserves. If future circumstances are such that we are not able to make the capital expenditures necessary to convert potential undeveloped reserves to developed reserves, we will not replace the amount of reserves produced and sold and our reserves and oil and natural gas segment operating results and cash flows will decline accordingly, and we may be forced to sell some of our oil and natural gas segment assets under untimely or unfavorable terms. Any such curtailment or sale could have a material adverse effect on our business, financial condition and results of operations.

Future oil and natural gas operating results and cash flow are highly dependent upon our level of success in acquiring or finding additional reserves on an economic basis. We cannot guarantee that we will be successful in developing or acquiring additional reserves and our current financial resources may be insufficient to make such investments. Furthermore, if oil or natural gas prices increase, our cost for additional reserves also could increase.

**We may not realize an adequate return on oil and natural gas investments.** 

Drilling for oil and natural gas involves numerous risks, including the risk that we will not encounter commercially productive oil or natural gas reservoirs. The wells we drill or participate in may not be productive, and we may not recover all or any portion of our investment in those wells. If future oil and natural gas segment acquisition and development activities are not successful it could have an adverse effect on our future results of operations and financial condition.

**Oil and natural gas prices are highly volatile and further declines, or extended low prices will significantly affect our financial condition and results of operations.** 

Much of our revenues and cash flow are greatly dependent upon prevailing prices for oil and natural gas. Lower oil and natural gas prices not only decrease our revenues on a per unit basis, but also reduce the amount of oil and natural gas we can produce economically, if any. Prices that do not produce sufficient operating margins will have a material adverse effect on our operations, financial condition, operating cash flows, borrowing ability, reserves, and the amount of capital that we are able to allocate for the acquisition and development of oil and natural gas reserves.

Various factors beyond our control affect prices of oil and natural gas including, but not limited to, changes in supply and demand, market uncertainty, weather, worldwide political instability, foreign supply of oil and natural gas, the level of consumer product demand, government regulations and taxes, the price and availability of alternative fuels and the overall economic environment. Energy prices also are subject to other political and regulatory actions outside our control, which may include changes in the policies of the Organization of the Petroleum Exporting Countries or other developments involving or affecting oil-producing countries, or actions or reactions of the government of the U.S. in anticipation of or in response to such developments.

------

**The inability of one or more of our working interest partners to meet their obligations may adversely affect our financial results.**

For our operated properties, we pay expenses and bill our non-operating partners for their respective shares of costs. Some of our non-operating partners may experience liquidity problems and may not be able to meet their financial obligations. Nonperformance by a non-operating partner could result in significant financial losses.

Liquidity problems encountered by our working interest partners or the third party operators of our non-operated properties also may result in significant financial losses as the other working interest partners or third party operators may be unwilling or unable to pay their share of the costs of projects as they become due. In the event a third party operator of a non-operated property becomes insolvent, it may result in increased operating expenses and cash required for abandonment liabilities if the Company is required to take over operatorship.

**We may incur material costs to comply with or as a result of health, safety, and environmental laws and regulations.**

The oil and natural gas industry is subject to extensive environmental regulation pursuant to local, provincial and federal legislation. A violation of that legislation may result in the imposition of fines or the issuance of "clean up" orders. Legislation regulating the oil and natural gas industry may be changed to impose higher standards and potentially more costly obligations. Although we have recorded a provision in our financial statements relating to our estimated future environmental and reclamation obligations that we believe is reasonable, we cannot guarantee that we will be able to satisfy our actual future environmental and reclamation obligations.

Barnwell's oil and natural gas segment is subject to the provisions of the Alberta Energy Regulator's ("AER") Licensee Life-Cycle Management Program via a Licensee Capability Assessment ("LCA"). Under this program the AER assesses the corporate health of the Company and considers a wider variety of factors than those considered under the previous program. The LCA establishes clear expectations for industry with regards to the management of liabilities throughout the entire lifecycle of oil and gas projects. Factors considered are grouped into six factor groups, these being current financial distress, liability magnitude, resources lifespan, operations compliance, closure efficiency and administrative compliance. These factors are compared to peer operators and ranked into three "Tiers". Under the AER, an inventory reduction program has also been implemented which requires mandatory annual minimum expenditures towards outstanding decommissioning and reclamation obligations in accordance with AER targets which are adjusted by the AER on an annual basis. The target for 2026 is 6.5% of an individual company's inactive liability. These targets became effective January 1, 2022.

The AER may require purchasers of AER licensed oil and natural gas assets to be within Tiers 1 or 2 overall rankings in the six factors group. This requirement for well transfers hinders our ability to generate capital by selling oil and natural gas assets as there are less qualified buyers.

The AER may require the Company to provide a security deposit if assessed at Tier 3. Diverting funds to the AER in the future would result in the diversion of cash on hand and operating cash flows that could otherwise be used to fund oil and natural gas reserve replacement efforts, which could in turn have a material adverse effect on our business, financial condition and results of operations. If Barnwell fails to comply with the requirements of the LCA program, Barnwell's oil and natural gas subsidiary would be subject to the AER's enforcement provisions which could include suspension of operations and non-

------

compliance fees and could ultimately result in the AER serving the Company with a closure order to shut-in all operated wells. Additionally, if Barnwell is non-compliant, the Company would be prohibited from transferring well licenses which would prohibit us from selling any oil and natural gas assets until the required cash deposit is made with the AER.

We are not fully insured against certain environmental risks, either because such insurance is not available or because of high premium costs. In particular, insurance against risks from environmental pollution occurring over time, as opposed to sudden and catastrophic damages, is not available on economically reasonable terms. Accordingly, any site reclamation or abandonment costs actually incurred in the ordinary course of business in a specific period could negatively impact our cash flow. Should we be unable to fully fund the cost of remedying an environmental problem, we might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy.

**We may fail to fully identify potential problems related to acquired reserves or to properly estimate those reserves.**

We periodically evaluate acquisitions of reserves, properties, prospects and leaseholds and other strategic transactions that appear to fit within our overall business strategy. Our evaluation includes an assessment of reserves, future oil and natural gas prices, operating costs, potential for future drilling and production, validity of the seller's title to the properties and potential environmental issues, litigation and other liabilities.

In connection with these assessments, we perform a review of the subject properties that we believe to be generally consistent with industry practices. Our review will not reveal all existing or potential problems nor will it permit us to become sufficiently familiar with the properties to fully assess their deficiencies and potential recoverable reserves. Inspections may not always be performed on every well, and environmental problems are not necessarily observable even when an inspection is undertaken. Even when problems are identified, the seller of the properties may be unwilling or unable to provide effective contractual protection against all or part of the problems. We often are not entitled to contractual indemnification for environmental liabilities or title defects in excess of the amounts claimed by us before closing and acquire properties on an "as is" basis.

There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves and future production rates and costs with respect to acquired properties, and actual results may vary substantially from those assumed in the estimates.

**If oil and natural gas prices decline and remain low, we may be required to take write-downs of the carrying values of our oil and natural gas properties.**

Oil and natural gas prices affect the value of our oil and natural gas properties as determined in our full cost ceiling calculation. Any future ceiling test write-downs will result in reductions of the carrying value of our oil and natural gas properties and an equivalent charge to earnings.

------

**The oil and natural gas industry is highly competitive.**

We compete for capital, acquisitions of reserves, undeveloped lands, skilled personnel, access to drilling rigs, service rigs and other equipment, access to processing facilities, pipeline capacity and in many other respects with a substantial number of other organizations, most of which have greater technical and financial resources than we do. Some of these organizations explore for, develop and produce oil and natural gas, carry on refining operations and market oil and other products on a worldwide basis. As a result of these complementary activities, some of our competitors may have competitive resources that are greater and more diverse than ours. Furthermore, many of our competitors may have a competitive advantage when responding to factors that affect demand for oil and natural gas production, such as changing prices and production levels, the cost and availability of alternative fuels and the application of government regulations. If our competitors are able to capitalize on these competitive resources, it could adversely affect our revenues and profitability.

**We are not the operator and have limited influence over the operations of certain of our oil and natural gas properties.**

We hold minority interests in certain of our oil and natural gas properties. As a result, we cannot control the pace of exploration or development, major decisions affecting the drilling of wells, the plan for development and production at non-operated properties, or the timing and amount of costs related to abandonment and reclamation activities although contract provisions give Barnwell certain consent rights in some matters. The operator's influence over these matters can affect the pace at which we incur capital expenditures. Additionally, as certain underlying joint venture data is not accessible to us, we depend on the operators at non-operated properties to provide us with reliable accounting information. We also depend on operators and joint operators to maintain the financial resources to fund their share of all abandonment and reclamation costs.

**Actual reserves will vary from reserve estimates.**

Estimating reserves is inherently uncertain and the reserves estimation process involves significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data. The reserve data and standardized measures set forth herein are only estimates. Ultimately, actual reserves attributable to our properties will vary from estimates, and those variations may be material. The estimation of reserves involves a number of factors and assumptions, including, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• oil and natural gas prices as prescribed by SEC regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• historical production from our wells compared with production rates from similar producing wells in the area;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• future commodity prices, production and development costs, royalties and capital expenditures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• initial production rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• production decline rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ultimate recovery of reserves;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• success of future development activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• marketability of production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effects of government regulation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other government levies that may be imposed over the producing life of reserves.

------

If these factors, assumptions and prices prove to be inaccurate, actual results may vary materially from reserve estimates.

**Part of our strategy involves using some of the latest available horizontal drilling and completion techniques. The results of our drilling are subject to drilling and completion technique risks, and results may not meet our expectations for reserves or production.**

&nbsp;&nbsp;&nbsp;&nbsp;Many of our operations involve, and are planned to utilize, the latest drilling and completion techniques as developed by our service providers in order to maximize production and ultimate recoveries and therefore generate the highest possible returns. Risks we face while completing our wells include, but are not limited to, the inability to fracture the planned number of stages, the inability to run tools and other equipment the entire length of the well bore during completion operations, the inability to recover such tools and other equipment, and the inability to successfully clean out the well bore after completion of the final fracture stimulation. Ultimately, the success of these drilling and completion techniques can only be evaluated over time as more wells are drilled and production profiles are established over a sufficiently long time period. If our drilling results are less than anticipated or we are unable to execute our drilling program because of capital constraints, lease expirations, limited access to gathering systems and takeaway capacity, and/or prices for crude oil, natural gas, and natural gas liquids decline, then the return on our investment for a particular project may not be as attractive as we anticipated and we could incur material write-downs of oil and gas properties and the value of our undeveloped acreage could decline in the future.

&nbsp;&nbsp;&nbsp;&nbsp;Production and reserves, if any, attributable to the use of enhanced recovery methods are inherently difficult to predict. If our enhanced recovery methods do not allow for the extraction of crude oil, natural gas, and associated liquids in a manner or to the extent that we anticipate, we may not realize an acceptable return on our investments in such projects.

**Delays in business operations could adversely affect the amount and timing of our cash inflows.**

In addition to the usual delays in payment by purchasers of oil and natural gas to the operators of our properties, and the delays of those operators in remitting payment to us, payments between any of these parties may also be delayed by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrictions imposed by lenders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• accounting delays;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays in the sale or delivery of products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays in the connection of wells to a gathering system;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• blowouts or other accidents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adjustments for prior periods;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recovery by the operator of expenses incurred in the operation of the properties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the establishment by the operator of reserves for these expenses.

Any of these delays could expose us to additional third party credit risks.

**The oil and natural gas market in which we operate exposes us to potential liabilities that may not be covered by insurance.**

Our operations are subject to all of the risks associated with the operation and development of oil and natural gas properties, including the drilling of oil and natural gas wells, and the production and

------

transportation of oil and natural gas. These risks include encountering unexpected formations or pressures, premature declines of reservoirs, blow-outs, equipment failures and other accidents, cratering, sour gas releases, uncontrollable flows of oil, natural gas or well fluids, adverse weather conditions, pollution, other environmental risks, fires and spills. A number of these risks could result in personal injury, loss of life, or environmental and other damage to our property or the property of others.

While we carry various levels of insurance, we could be affected by civil, criminal, regulatory or administrative actions, claims or proceedings. We cannot fully protect against all of the risks listed above, nor are all of these risks insurable. There is no assurance that any applicable insurance or indemnification agreements will adequately protect us against liability for the risks listed above. We could face substantial losses if an event occurs for which we are not fully insured or are not indemnified against or a customer or insurer fails to meet its indemnification or insurance obligations. In addition, there can be no assurance that insurance will continue to be available to cover any or all of these risks, or, even if available, that insurance premiums or other costs will not rise significantly in the future, so as to make the cost of such insurance prohibitive.

Deficiencies in operating practices and record keeping, if any, may increase our risks and liabilities relating to incidents such as spills and releases and may increase the level of regulatory enforcement actions.

**Our operations are subject to domestic and foreign government regulation and other risks, particularly in Canada and the U.S.**

Barnwell's oil and natural gas operations are affected by political developments and laws and regulations, particularly in Canada and the U.S., such as restrictions on production, restrictions on imports and exports, the maintenance of specified reserves, tax increases and retroactive tax claims, expropriation of property, cancellation of contract rights, environmental protection controls, environmental compliance requirements and laws pertaining to workers' health and safety. Further, the right to explore for and develop oil and natural gas on lands in Alberta is controlled by the government of that province. Changes in royalties and other terms of provincial leases, permits and reservations may have a substantial effect on Barnwell's operations. We derive a significant portion of our revenues from our operations in Canada; 91% in fiscal 2025.

Additionally, our ability to compete in the Canadian oil and natural gas industry may be adversely affected by governmental regulations or other policies that favor the awarding of contracts to contractors in which Canadian nationals have substantial ownership interests. Furthermore, we may face governmentally imposed restrictions or fees from time to time on the transfer of funds to the U.S.

Government regulations control and often limit access to potential markets and impose extensive requirements concerning employee safety, environmental protection, pollution control and remediation of environmental contamination. Environmental regulations, in particular, prohibit access to some markets and make others less economical, increase equipment and personnel costs and often impose liability without regard to negligence or fault. In addition, governmental regulations may discourage our customers' activities, reducing demand for our products and services.

------

**Changes in U.S. trade policy, including the imposition of tariffs and the resulting consequences, could adversely affect our business, prospects, financial condition, and operating results.**

There is currently significant uncertainty about the future relationship between the United States and Canada, including potential changes with respect to trade policies, treaties, tariffs, taxes, and other limitations on cross-border operations. Because all our oil and natural gas production is in Canada, changes in tariffs, trade barriers, and other regulatory requirements could have an adverse effect on our business, prospects, financial condition and operating results, the extent of which cannot be predicted with certainty at this time.

**Legislation, regulation, and other government actions and shifting customer preferences and other private efforts related to greenhouse gas ("GHG") emissions and climate change could increase our operational costs and reduce demand for our oil and natural gas, resulting in a material adverse effect on the Company's results of operations and financial condition.**

Barnwell may experience challenges from the impacts of international and domestic legislation, regulation, or other government actions relating to GHG emissions (e.g., carbon dioxide and methane) and climate change. International agreements and national, regional, and state legislation and regulatory measures that aim to directly or indirectly limit or reduce GHG emissions are in various stages of implementation. Many of these actions, as well as customers' preferences and use of oil and natural gas or substitute products, are beyond the Company's control. Similar to any significant changes in the regulatory environment, GHG emissions and climate change-related legislation, regulation, or other government actions may curtail profitability in the oil and gas sector, or render the extraction of the Company's hydrocarbon resources economically infeasible. In particular, GHG emissions-related legislation, regulations, and other government actions and shifting consumer preferences and other private efforts aimed at reducing GHG emissions may result in increased and substantial capital, compliance, operating, and maintenance costs and could, among other things, reduce demand for the Company's oil and natural gas; adversely affect the economic feasibility of the Company's resources; impact or limit our business plans; and adversely affect the Company's sales volumes, revenues, margins and reputation.

The ultimate impact of GHG emissions and climate change-related agreements, legislation, regulation, and government actions on the Company's financial performance is highly uncertain because the Company is unable to predict with certainty, the outcome of political decision-making processes, including the actual laws and regulations enacted, the variables and tradeoffs that inevitably occur in connection with such processes, and market conditions.

**Compliance with foreign tax and other laws may adversely affect our operations.**

Tax and other laws and regulations are not always interpreted consistently among local, regional and national authorities. Income tax laws, other legislation or government incentive programs relating to the oil and natural gas industry may in the future be changed or interpreted in a manner that adversely affects us and our stockholders. It also is possible that in the future we will be subject to disputes concerning taxation and other matters in Canada, including the manner in which we calculate our income for tax purposes, and these disputes could have a material adverse effect on our financial performance.

------

**Unforeseen title defects may result in a loss of entitlement to production and reserves.**

Although we conduct title reviews in accordance with industry practice prior to any purchase of resource assets or property, such reviews do not guarantee that an unforeseen defect in the chain of title will not arise and defeat our title to the purchased assets. If such a defect were to occur, our entitlement to the production from such purchased assets could be jeopardized.

*Risks Related to Land Investment Segment*

**Receipt of future payments from KD II and cash distributions from the Kukio Resort Land Development Partnerships is dependent upon the developer's continued efforts and ability to develop the property.**

**We hold investment interests in unconsolidated land development partnerships, which are accounted for using the equity method of accounting, in which we do not have a controlling interest. These investments involve risks and are highly illiquid.**

These investments involve risks which include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the lack of a controlling interest in these partnerships and, therefore, the inability to require that the entities sell assets, return invested capital or take any other action without obtaining the majority vote of partners;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• potential for future additional capital contributions to fund operations and development activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the adverse impact on overall profitability if the entities do not achieve the financial results projected;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the reallocation of amounts of capital from other operating initiatives and/or an increase in indebtedness to pay potential future additional capital contributions, which could in turn restrict our ability to access additional capital when needed or to pursue other important elements of our business strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• undisclosed, contingent or other liabilities or problems, unanticipated costs, and an inability to recover or manage such liabilities and costs and which could delay or prevent development of the real estate held by the land development partnerships; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain underlying partnership data is not accessible to us, therefore we depend on the general partner to provide us with reliable accounting information.

**Our land investment business is concentrated in the state of Hawaii. As a result, our financial results are dependent on the economic growth and health of Hawaii, particularly the island of Hawaii.**

Barnwell's land investment segment is impacted by the condition of Hawaii's real estate market, which is affected by Hawaii's economy and Hawaii's tourism industry, as well as the U.S. and world economies in general. Any future cash flows from Barnwell's land development activities are subject to, among other factors, the level of real estate activity and prices, the demand for new housing and second homes on the island of Hawaii, the rate of increase in the cost of building materials and labor, the introduction of building code modifications, changes to zoning laws, and the level of confidence in Hawaii's economy.

------

**The occurrence of natural disasters in Hawaii could adversely affect our business.**

The occurrence of a natural disaster in Hawaii such as, but not limited to, earthquakes, landslides, hurricanes, tornadoes, tsunamis, volcanic activity, droughts and floods, could have a material adverse effect on our land investments. The occurrence of a natural disaster could also cause property and flood insurance rates and deductibles to increase, which could reduce demand for real estate in Hawaii.

**ITEM 1C.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CYBERSECURITY**

We recognize the importance of assessing, identifying, and managing material risks from cybersecurity threats. Our policies, standards, and procedures for assessing, identifying, and managing material risks from cybersecurity threats are integrated into our overall risk management system. In this regard, we use various tools and processes to help prevent, identify, and resolve any identified vulnerabilities and security incidents in a timely manner. These include, but are not limited to, internal reporting, periodic employee awareness updates, engaging experts and third-party monitoring and detection tools.

We employ third-party information technology ("IT") consultants to manage our information technology environment and help manage and assess cybersecurity risks.

Our IT Steering Committee, comprised of our Chief Executive Officer, our Chief Financial Officer, and our General Counsel, oversees efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which includes oversight over our third-party IT consultants, monitoring systems and employee engagement. Our senior management team is responsible for reporting any identified cybersecurity risks to the Audit Committee of our Board of Directors.

The Audit Committee of our Board of Directors meets periodically with management to review the Company's overall policies with respect to risk assessment and risk management, including a review the systems and processes implemented by management to identify, assess, manage, and mitigate cybersecurity risks. Our senior management is responsible for the day-to-day supervision of the material risks we may face.

Our risks from cybersecurity threats have not affected or are reasonably not likely to materially affect our business strategy, results of operations, or financial condition.

**Corporate Offices**

Barnwell's corporate headquarters is located in Honolulu, Hawaii, in a commercial office building under a lease that expires in February 2026.

Subsequent to fiscal 2025, Barnwell made the decision to relocate its corporate headquarters to co-head offices in Houston, Texas and Calgary, Alberta. The closure of the Hawaii office is scheduled to occur in early calendar year 2026. This decision reflects the Company's ongoing efforts to streamline operations and reduce general and administrative expenses.

On March 26, 2025, the Company commenced a lawsuit against the Sherwood Group in the Delaware Chancery Court, seeking, among other remedies, declaratory judgment that the Sherwood Group's purported notice to nominate certain individuals for election to the Company's board of directors at the 2025 Annual Meeting of stockholders was invalid and injunctive relief to enjoin the Sherwood Group from presenting its slate of nominees at the 2025 Annual Meeting due to the failure of the Sherwood Group to comply with the advance notice provisions of the Company's Bylaws.

On April 21, 2025, the Sherwood Group filed an answer to the Company's complaint, counterclaims against the Company and a third-party complaint against Alexander Kinzler, Kenneth Grossman and Joshua Horowitz in the Delaware Chancery Court, seeking, amongst other things, dismissal of all claims brought by the Company against the Sherwood Group, declaratory judgment that the Company's directors breached their fiduciary duties, and injunctive relief to enjoin the Company from (i) applying the Company's Bylaws to prevent the Sherwood Group from nominating its slate of nominees set forth in the defective Sherwood nomination notice for election at the 2025 Annual Meeting and (ii) filing or distributing further proxy solicitation materials for the 2025 Annual Meeting until the Delaware Chancery Court issued a ruling determining whether the Sherwood Group complied with the advance notice provisions of the Company's Bylaws.

After a trial, on May 21, 2025, the Delaware Chancery Court ruled in favor of the Company and the Board of Directors, and held that the defective Sherwood nomination notice was invalid and the Board properly applied the Bylaws in response to the defective Sherwood nomination notice and found that Mr. Kinzler, Mr. Grossman and Mr. Horowitz did not breach their fiduciary duties. The Sherwood Group chose not to appeal the Court's decision. Accordingly, the Board did not permit the Sherwood nominees to be presented for election at the 2025 Annual Meeting, which was held in September 2025.

The following discussion is intended to assist in the understanding of the Consolidated Balance Sheets of Barnwell Industries, Inc. and subsidiaries (collectively referred to herein as "Barnwell," "we," "our," "us" or the "Company") as of September 30, 2025 and 2024, and the related Consolidated Statements of Operations, Comprehensive Loss, Equity, and Cash Flows for the years ended September 30, 2025 and 2024. This discussion should be read in conjunction with the consolidated financial statements and related Notes to Consolidated Financial Statements included in this report.

On March 14, 2025, the Company entered into and completed the sale of its wholly-owned subsidiary, Water Resources. Water Resources drills water wells and installs and repairs water pumping systems in Hawaii and represented our contract drilling segment. As a result of the sale, the Company has classified the related assets and liabilities and the results of its contract drilling business as discontinued operations in the consolidated financial statements for all periods presented. Prior to the sale, the Company did not have any assurances that a sale of Water Resources was likely to occur. Unless otherwise noted, the discussions below pertains only to Barnwell's continuing operations. For information on discontinued operations, refer to Note 3 "Discontinued Operations" in the Notes to Consolidated Financial Statements in Item 8 of this report.

**Critical Accounting Policies and Estimates**

The Company considers an accounting estimate to be critical if the accounting estimate requires the Company to make assumptions that are difficult or subjective about matters that were highly uncertain at the time that the accounting estimate was made, and changes in the estimate that are reasonably likely to occur in periods subsequent to the period in which the estimate was made, or use of different estimates that the Company could have used in the current period, would have a material impact on the Company's financial condition or results of operations. The most critical accounting policies inherent in the preparation of the Company's consolidated financial statements are described below. We continue to monitor our accounting policies to ensure proper application of current rules and regulations.

*Oil and Natural Gas Properties - full cost ceiling calculation and depletion*

<u>Policy Description</u>

We use the full cost method of accounting for our oil and natural gas properties under which we are required to conduct quarterly calculations of a "ceiling," or limitation, on the carrying value of oil and natural gas properties . The ceiling limitation is the sum of 1) the discounted present value (at 10%), using average first-day-of-the-month prices during the 12-month period ending as of the balance sheet date held constant over the life of the reserves (except where prices are defined by contractual arrangements), of Barnwell's estimated future net cash flows from estimated production of proved oil and natural gas reserves, less estimated future expenditures to be incurred in developing and producing the proved reserves but excluding future cash outflows associated with settling asset retirement obligations with the exception of those associated with proved undeveloped reserves from wells that are to be drilled in the future; plus 2) the cost of major development projects and unproven properties not subject to depletion, if any; plus 3) the lower of cost or estimated fair value of unproven properties included in costs subject to depletion; less 4) related income tax effects. If net capitalized costs exceed this limit, the excess is expensed.

------

All items classified as unevaluated and unproved properties are assessed on a quarterly basis for possible impairment or reduction in value. Properties are assessed on an individual basis or as a group if properties are individually insignificant. The assessment includes consideration of various factors, including, but not limited to, the following: intent to drill; remaining lease term; geological and geophysical evaluations; drilling results and activity; assignment of proved reserves; and economic viability of development if proved reserves are assigned. During any period in which these factors indicate an impairment, the cumulative drilling costs incurred to date for such property and all or a portion of the associated leasehold costs are transferred to the full cost pool and become subject to amortization.

<u>Judgments and Assumptions</u>

The estimate of our oil and natural gas reserves is a major component of the ceiling calculation and represents the component that requires the most subjective judgments. Estimates of reserves are forecasts based on engineering data, historical data, projected future rates of production and the timing of future expenditures. The process of estimating oil and natural gas reserves requires substantial judgment, resulting in imprecise determinations, particularly for new discoveries. Our reserve estimates are prepared at least annually by independent petroleum reserve engineers. The passage of time provides more quantitative and qualitative information regarding estimates of reserves, and revisions are made to prior estimates to reflect updated information. A portion of the revisions are attributable to changes in the rolling 12-month average first-day-of-the-month prices, which impact the economics of producible reserves. In the last three fiscal years, annual revisions to our reserve volume estimates have averaged 18% of the previous year's estimate, due in large part to the impacts of volatile oil and natural gas prices which change the economic viability of producing such reserves and changes in estimated proved undeveloped reserves which can fluctuate from year to year depending upon the Company's plans and ability to fund the capital expenditures necessary to develop such reserves. There can be no assurance that more significant revisions will not be necessary in the future. If future significant revisions are necessary that reduce previously estimated reserve quantities, such revisions could result in a write-down of oil and natural gas properties.

If reported reserve volumes were revised downward by 5% at the end of fiscal 2025, the ceiling limitation for Canada would have decreased approximately $636,000 which would not have resulted in a ceiling impairment before income taxes due to sufficient room between the ceiling and the carrying value of Canadian oil and natural gas properties at the end of fiscal 2025 of approximately $2,949,000.

In addition to the impact of the estimates of proved reserves on the calculation of the ceiling, estimated proved reserves are also a significant component of the quarterly calculation of depletion expense. The lower the estimated reserves, the higher the depletion rate per unit of production. Conversely, the higher the estimated reserves, the lower the depletion rate per unit of production. If reported reserve volumes were revised downward by 5% as of the beginning of fiscal 2025, depletion for fiscal 2025 would have increased by approximately $122,000.

While the quantities of proved reserves require substantial judgment, the associated prices of oil, natural gas and natural gas liquids reserves are the average first-day-of-the-month prices during the 12-month period ending in the reporting period on a constant basis as prescribed by SEC regulations. Additionally, the applicable discount rate that is used to calculate the discounted present value of the reserves is mandated at 10%. Costs included in future net revenues are determined in a similar manner. As such, the future net revenues associated with the estimated proved reserves are not based on an assessment of future prices or costs.

------

*Income Taxes*

<u>Policy Description</u>

Income taxes are determined using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax impacts of differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Deferred income tax assets are routinely assessed for realizability. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax asset will not be realized.

Barnwell recognizes the financial statement effects of tax positions when it is more likely than not that the position will be sustained by a taxing authority.

<u>Judgments and Assumptions</u>

We make estimates and judgments in determining our income tax expense for each reporting period. Significant changes to these estimates could result in an increase or decrease in our tax provision in future periods. We are also required to make judgments about the recoverability of deferred tax assets and when it is more likely than not that all or a portion of deferred tax assets will not be realized, a valuation allowance is provided. We consider available positive and negative evidence and available tax planning strategies when assessing the realizability of deferred tax assets. Accordingly, changes in our business performance and unforeseen events could require a further increase in the valuation allowance or a reversal in the valuation allowance in future periods. This could result in a charge to, or an increase in, income in the period such determination is made, and the impact of these changes could be material.

In addition, Barnwell operates within the U.S. and Canada and is subject to audit by taxing authorities in these jurisdictions. Barnwell records accruals for the estimated outcomes of these audits, and the accruals may change in the future due to new developments in each matter. Tax benefits are recognized when we determine that it is more likely than not that such benefits will be realized. Management evaluates its potential exposures from tax positions taken that have or could be challenged by taxing authorities. These potential exposures result because taxing authorities may take positions that differ from those taken by management in the interpretation and application of statutes, regulations and rules. Management considers the possibility of alternative outcomes based upon past experience, previous actions by taxing authorities (e.g., actions taken in other jurisdictions) and advice from tax experts. Where uncertainty exists due to the complexity of income tax statutes and where the potential tax amounts are significant, we generally seek independent tax opinions to support our positions. If our evaluation of the likelihood of the realization of benefits is inaccurate, we could incur additional income tax and interest expense that would adversely impact earnings, or we could receive tax benefits greater than anticipated which would positively impact earnings, either of which could be material.

------

**Overview**

Barnwell is engaged in the following lines of business: 1) acquiring, developing, producing and selling oil and natural gas in Canada and the U.S. (oil and natural gas segment) and 2) leasehold land interests in Hawaii (land investment segment).

*Oil and Natural Gas Segment*

Barnwell is involved in the acquisition and development of oil and natural gas properties primarily in the Twining area of Alberta, Canada, where we initiate and participate in acquisition and developmental operations for oil and natural gas on properties in which we have an interest, and evaluate proposals by third parties with regard to participation in such exploratory and developmental operations elsewhere. Additionally, through its wholly-owned subsidiaries BOK and Barnwell Texas, Barnwell was, until August 8, 2025, involved in non-operated oil and natural gas investments in Oklahoma and Texas, respectively.

Barnwell sells all of its Canadian and U.S. oil and natural gas under short-term contracts with marketers based on prices indexed to market prices. The price of natural gas, oil and natural gas liquids is freely negotiated between the buyers and sellers. Oil and natural gas prices are determined by many factors that are outside of our control. Market prices for oil and natural gas products are dependent upon factors such as, but not limited to, changes in market supply and demand, which are impacted by overall economic activity, changes in weather, pipeline capacity constraints, inventory storage levels, and output. Oil and natural gas prices are very difficult to predict and fluctuate significantly. Natural gas prices tend to be higher in the winter than in the summer due to increased demand, although this trend has become less pronounced due to the increased use of natural gas to generate electricity for air conditioning in the summer and increased natural gas storage capacity in North America.

Oil and natural gas exploration, development and operating costs generally follow trends in product market prices, thus in times of higher product prices the cost of exploring, developing and operating the oil and natural gas properties will tend to escalate as well. Capital expenditures are required to fund the exploration, development, and production of oil and natural gas. Cash outlays for capital expenditures are largely discretionary, however, a minimum level of capital expenditures is required to replace depleting reserves. Due to the nature of oil and natural gas exploration and development, significant uncertainty exists as to the ultimate success of any drilling effort.

*Land Investment Segment*

Through Barnwell's 77.6% interest in Kaupulehu Developments, 75% interest in KD Kona, and 34.45% non-controlling interest in KKM Makai, the Company's land investment interests include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The right to receive percentage of sales payments from KD I resulting from the sale of single-family residential lots by KD I, within Increment I of the Kaupulehu Lot 4A area located in the North Kona District of the island of Hawaii. However, in the quarter ended March 31, 2024, the last two remaining single-family lots in Increment I were sold and there are no more lots available for sale in Increment I. Kaupulehu Developments was entitled to receive payments from KD I based on 10% of the gross receipts from KD I's sales at Increment I. Increment I is an area zoned for approximately 80 single-family lots.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The right to receive 15% of the distributions of KD II, the cost of which is to be solely borne by KDK out of its 55% ownership interest in KD II, plus a priority payout of 10% of KDK's cumulative net profits derived from Increment II sales subsequent to Phase 2A, up to a maximum of $3,000,000. Such interests are limited to distributions or net profits interests and Barnwell does not have any partnership interest in KD II or KDK through its interest in Kaupulehu Developments. Barnwell also has rights to three single-family residential lots in Phase 2A of Increment II, and four single-family residential lots in phases subsequent to Phase 2A when such lots are developed by KD II, all at no cost to Barnwell. Barnwell is committed to commence construction of improvements within 90 days of the transfer of the four lots in the phases subsequent to Phase 2A as a condition of the transfer of such lots. Also, in addition to Barnwell's existing obligations to pay professional fees to certain parties based on percentages of its gross receipts, Kaupulehu Developments is obligated to pay an amount equal to 0.72% and 0.20% of the cumulative net profits of KD II to KD Development, LLC and a pool of various individuals, respectively, all of whom are partners of KKM and are unrelated to Barnwell. The remaining acreage within Increment II is not yet under development, and there is no assurance that development of such acreage will in fact occur. No definitive development plans have been made by KD II, the developer of Increment II, as of the date of this report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An indirect 19.6% non-controlling ownership interest in KD Kukio Resorts, LLLP, KD Maniniowali, LLLP and KD I and an indirect 10.8% non-controlling ownership interest in KD II through KDK. These entities own certain real estate and development rights interests in the Kukio, Maniniowali and Kaupulehu portions of Kukio Resort, a private residential community on the Kona coast of the island of Hawaii, as well as Kukio Resort's real estate sales office operations. KDK was the developer of Kaupulehu Lot 4A Increments I and II. The partnerships derive income from the sale of residential parcels in Increment I, which is now completely sold, as well as from commissions on real estate resales by the real estate sales office and revenues resulting from the sale of private club memberships, a few of which remain available for sale.

The Kukio Resort Land Development Partnerships have remaining Increment I obligations to complete project amenities, infrastructure, beautification, and restoration of certain areas and therefore has yet to fully recognize its deferred profit on the Increment I project as a whole. The Increment I deferred profit at September 30, 2025 for the Kukio Resort Land Development Partnerships as a whole was approximately $4,500,000; the recognition of which is dependent upon the completion of the Increment I obligations. The Kukio Resort Land Development Partnerships have accrued estimated costs of these obligations of approximately $3,000,000. The Kukio Resort Land Development Partnerships currently appears to have the ability to fund those obligations but there are no assurances that it can ultimately do so in the future if unforeseen events occur. The Kukio Resort Land Development Partnerships will recognize the Increment I deferred revenue and costs of sales on a percentage completion basis as the cash outlays to complete the remaining project obligations are made. The Kukio Resort Land Development Partnerships' deferred profit and accrued costs to complete are not reflected in Barnwell's Consolidated Balance Sheets as we account for our investment in the Kukio Resort Land Development Partnerships under the equity method of accounting. No percentage of sales payments will be earned by Barnwell on any future recognition of Increment I deferred profit as such payments were already fully earned and received based on cash received by the Kukio Resort Land Development Partnerships as the Increment I lots were sold.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Approximately 1,000 acres of vacant leasehold land zoned conservation in the Kaupulehu Lot 4C area, which currently has no development potential without both a development agreement with the lessor and zoning reclassification. The lease terminates in December 2025.

In November 2025, Kaupulehu Developments entered into an agreement with Mr. David Johnston, the son of Mr. Terry Johnston, a partner in Kaupulehu Developments, to surrender any and all remaining rights for Increment II for $2,000,000 of which $70,000 was received. Additionally, the purchaser has the right to extend the closing by up to two years by making a $70,000 payment in each of the next two years, with those payments applied against the $2,000,000 purchase price. The closing of this transaction is entirely dependent on the purchaser and therefore may not happen.

Subsequent to fiscal 2025, pursuant to a unit purchase agreement KDK, of which Barnwell holds a 19.6% interest, agreed to sell KDK's interests in Increment II to Mr. David Johnston for $2,109,000. The unit purchase agreement is subject to due diligence, and there is no certainty that the transaction will close. Furthermore, there is also no assurance on the timing or amounts that the general partner of KDK would distribute upon a closing.

**Business Environment**

Our operations are located in Canada and in the state of Hawaii and Texas. Accordingly, our business performance is directly affected by macroeconomic conditions in those areas, as well as general economic conditions of the U.S. domestic and world economies.

*Oil and Natural Gas Segment*

Barnwell realized an average price for oil of $60.49 per barrel during the year ended September 30, 2025, a decrease of 9% from $66.49 per barrel realized during the prior year and realized an average price for natural gas of $1.27 per Mcf during the year ended September 30, 2025, a decrease of 10% from $1.41 per Mcf realized during the prior year. Oil and natural gas prices continue to be volatile over time and thus, the Company is unable to reasonably predict future prices and the impacts future prices will have on the Company.

*Land Investment Segment*

Future revenues from the sale of interest in leasehold land and any future cash distributions from our investment in the Kukio Resort Land Development Partnerships are dependent upon the potential future development or sale of the remaining portion of Increment II by KD II of Kaupulehu Lot 4A. The amount and timing of future land investment segment proceeds from percentage of sales payments and cash distributions from the Kukio Resort Land Development Partnerships are highly uncertain and out of our control, and there is no assurance with regards to the amounts of future payments from Increment II to be received or that the remaining acreage within Increment II will be developed. No definitive development plans have been made by KD II, the developer of Increment II, as of the date of this report.

**Results of Operations**

*Summary of Results From Continuing Operations*

The net loss from continuing operations attributable to Barnwell for fiscal 2025 totaled $7,115,000, a $3,010,000 increase from a net loss from continuing operations attributable to Barnwell of $4,105,000 in fiscal 2024. The following factors affected the results of operations for the current fiscal year as compared to the prior fiscal year:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• General and administrative expenses increased $1,807,000 due to $1,958,000 in new fees and costs incurred, net of $348,000 of estimated accrued insurance recoveries, related to a shareholder consent solicitation, various legal actions between the Sherwood Group and the Company and certain of its directors, and a proxy contest in the current year period as compared to the same period in the prior year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Equity in income from affiliates decreased $1,071,000 and land investment segment operating results, before non-controlling interests' share of such profits, decreased $500,000 due to the Kukio Resort Land Development Partnerships' sale of two lots in the prior year period, whereas there was no lots sold in the current year period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A $636,000 loss recognized in the current year period from the sale of all of the U.S. oil and natural gas properties, whereas there was no such loss in the prior year period; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A $192,000 foreign currency loss recorded in the current year period due to the effects of the foreign exchange rate changes on intercompany loans and advances as a result of the strengthening of the U.S. dollar against the Canadian dollar.

*General*

Barnwell conducts operations in the U.S. and Canada. Consequently, Barnwell is subject to foreign currency translation and transaction gains and losses due to fluctuations of the exchange rates between the Canadian dollar and the U.S. dollar. Barnwell cannot accurately predict future fluctuations of the exchange rates and the impact of such fluctuations may be material from period to period. To date, we have not entered into foreign currency hedging transactions. Foreign currency gains or losses on intercompany loans and advances that are not considered long-term investments in nature because management intends to settle these intercompany balances in the future are included in our statements of operations.

The average exchange rate of the Canadian dollar to the U.S. dollar decreased 3% in fiscal 2025, as compared to fiscal 2024 and the exchange rate of the Canadian dollar to the U.S. dollar decreased 3% at September 30, 2025, as compared to September 30, 2024. Accordingly, the assets, liabilities, stockholders' equity and revenues and expenses of Barnwell's subsidiaries operating in Canada have been adjusted to reflect the change in the exchange rates. Other comprehensive income and losses are not included in net earnings and net loss.

Other comprehensive income due to foreign currency translation adjustments, net of taxes, for fiscal 2025 was $75,000, a $75,000 change from other comprehensive loss due to foreign currency translation adjustments, net of taxes, of nil in fiscal 2024. There were no taxes on other comprehensive

------

income due to foreign currency translation adjustments in fiscal 2025 and 2024 due to a full valuation allowance on the related deferred tax assets.

________________________

(1)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The operating loss for Canada for the year ended September 30, 2024 includes a non-cash ceiling test impairment of $2,164,000.

(2)&nbsp;&nbsp;&nbsp;&nbsp; The operating (loss) profit for the United States for the years ended September 30, 2025 and 2024 includes non-cash ceiling test impairments of $865,000 and $721,000, respectively.

Oil and natural gas revenues decreased $3,833,000 (22%) from $17,396,000 in fiscal 2024 to $13,563,000 in fiscal 2025, primarily due primarily due to decreases in natural gas, oil, and natural gas liquids production, which decreased 18%, 14%, and 13%, respectively, in the current year period as compared to the same period in the prior year. The decrease in production was primarily the result of

------

natural declines in production from wells in the Company's Twining area as the wells age, and to a lesser extent due to properties sold in the prior year. Revenues also decreased due to a decrease in oil prices which decreased 9% as compared to the same period in the prior year.

In February 2025, the Company amended certain of its Canadian purchase and sales contracts to change the sales price on 1,055 gross Mcf per day of the Canadian natural gas it will sell during the period from April 1, 2025 to October 31, 2025 to a fixed index price before differentials of $1.95 Canadian dollars per Mcf, with remaining volumes continuing to be sold at spot prices. This per day volume of natural gas under this fixed index price contract was equivalent to approximately 38% of Canadian natural gas gross production per day for the year ended September 30, 2025. Additionally, in September 2025, the Company amended the sales price on 1,583 gross Mcf per day of the Canadian natural gas it will sell during the period from November 1, 2025 to March 31, 2026 to a fixed index price before differentials of $3.03 Canadian dollars per Mcf, with remaining volumes continuing to be sold at spot prices. This per day volume of natural gas under this fixed index price contract that will affect the period from November 1, 2025 to March 31, 2026, is equivalent to approximately 58% of Canadian natural gas gross production per day for the year ended September 30, 2025. These natural gas contracts were eligible for and elected as normal purchase and normal sales exception contracts and were thus excluded from derivative accounting.

In June 2025, the Company amended the sales price on 100 gross barrels per day of the Canadian oil that it will sell during the period from July 1, 2025 to December 31, 2025 to a fixed index price before differentials of $70.35 per net barrel, with remaining volumes continuing to be sold at spot prices. This per day volume of oil under this fixed index price was equivalent to approximately 19% of Canadian oil gross production per day for the year ended September 30, 2025. These oil contracts were eligible for and elected as normal purchase and normal sales exception contracts and were thus excluded from derivative accounting.

Subsequently, in October 2025, the Company amended the sales price on 1,055 gross Mcf per day of the Canadian natural gas it will sell during the period from April 1, 2026 to October 31, 2026 to a fixed index price before differentials of $2.94 Canadian dollars per Mcf, with remaining volumes continuing to be sold at spot prices. This per day volume of natural gas under this fixed index price contract that will affect the period from April 1, 2026 to October 31, 2026, is equivalent to approximately 38% of Canadian natural gas gross production per day for the year ended September 30, 2025.

Oil and natural gas operating expenses decreased $883,000 (9%) from $9,849,000 in fiscal 2024 to $8,966,000 in fiscal 2025, primarily due to decreases in production in the current year, partially offset by an increase in workovers in the current year, as compared to the prior year.

&nbsp;&nbsp;&nbsp;&nbsp;Oil and natural gas segment depletion decreased $1,803,000 (36%) from $4,947,000 in fiscal 2024 to $3,144,000 in fiscal 2025, primarily due to decreases in the depletion rate and due to decreases in production in the current year as compared to the prior year. The depletion rate decreased as a result of a decrease in the depletable base from significant ceiling test impairments between the prior year period and the current year period.

On August 8, 2025, Barnwell entered into an agreement with an independent third party to sell all of its working interests in its U.S. oil and natural gas assets for a sales price of $2,300,000. The sales price per the agreement was adjusted for customary purchase price adjustments to reflect the economic activity from the effective date of July 1, 2025 to the closing date August 8, 2025. The Company recognized a loss on the sale of $636,000 before related income taxes in the year ended September 30, 2025. The U.S. oil and natural gas assets were located in the states of Texas and Oklahoma and were owned by wholly-

------

owned subsidiaries of Barnwell. As a result of the sale, the Company no longer owns any oil and natural gas assets in the U.S., however, the Company will continue to explore for oil and natural gas opportunities in the U.S.

*Sale of interest in leasehold land*

Kaupulehu Developments was entitled to receive a percentage of the gross receipts from the sales of lots and/or residential units in Increment I by KD I.

The following table summarizes the revenues received from KD I and the amount of fees directly related to such revenues:

---

| | | |
|:---|:---|:---|
| | Year ended September 30, | Year ended September 30, |
| | **2025** | 2024 |
| Sale of interest in leasehold land: |  |  |
| &nbsp;&nbsp;&nbsp;Revenues - sale of interest in leasehold land | $**—** | $500000 |
| &nbsp;&nbsp;&nbsp;Fees - included in general and administrative expenses | **—** | (61000) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sale of interest in leasehold land, net of fees paid | $**—** | $439000 |

---

No lots were sold during the year ended September 30, 2025. During the year ended September 30, 2024, Barnwell received $500,000 in percentage of sales payments from KD I from the sale of the last two single-family lots within Increment I.

There is an Increment II owned by KD II in which the Company has a 10.8% indirect non-controlling ownership interest. There is no assurance with regards to the amounts of future sales from Increment II or that the remaining acreage within Increment II will be developed. No definitive development plans have been made by KD II, the developer of Increment II, as of the date of this report.

In November 2025, Kaupulehu Developments entered into an agreement with Mr. David Johnston, the son of Mr. Terry Johnston, a partner in Kaupulehu Developments, to surrender any and all remaining rights for Increment II for $2,000,000 of which $70,000 was. Additionally, the purchaser has the right to extend the closing by up to two years by making a $70,000 payment in each of the next two years, with those payments applied against the $2,000,000 purchase price. The closing of this transaction is entirely dependent on the purchaser and therefore may not happen.

Subsequent to fiscal 2025, pursuant to a unit purchase agreement KDK, of which Barnwell holds a 19.6% interest, agreed to sell KDK's interests in Increment II to Mr. David Johnston for $2,109,000. The unit purchase agreement is subject to due diligence, and there is no certainty that the transaction will close. Furthermore, there is also no assurance on the timing or amounts that the general partner of KDK would distribute upon a closing.

*General and administrative expenses*

General and administrative expenses increased $1,807,000 (35%) to $6,937,000 in fiscal 2025, as compared to $5,130,000 in fiscal 2024. The increase was primarily due to $1,958,000 in new fees and costs incurred, net of $348,000 of estimated accrued insurance recoveries receivable, for legal services, proxy solicitation, proxy advisory, and public relations costs related to a shareholder consent solicitation,

------

various legal actions between the Sherwood Group and the Company and certain of its directors, and a proxy contest in the current year period as compared to the same period in the prior year.

The amount of estimated accrued insurance recoveries receivable aforementioned above is management's best estimate of the probable recoverable amount under the insurance policies. While the insurer has confirmed that certain costs incurred by the Company are eligible for claim under the Company's insurance policies, the amount ultimately recoverable through insurance is dependent upon the insurer's completion of their review of eligible legal costs incurred and the recoverable amount may differ from management's estimate.

*Depletion, depreciation, and amortization*

Depletion, depreciation, and amortization decreased $1,804,000 (36%) from $4,950,000 in fiscal 2024 to $3,146,000 in fiscal 2025, primarily due to decreases in the depletion rate and decreases in production, as discussed in the "Oil and natural gas" section above.

*Impairment of assets*

Under the full cost method of accounting, the Company performs quarterly oil and natural gas ceiling test calculations. Changes in the 12-month rolling average first-day-of-the-month prices for oil, natural gas and natural gas liquids prices (except where prices are defined by contractual arrangements), the value of reserve additions as compared to the amount of capital expenditures to obtain them, and changes in production rates and estimated levels of reserves, future development costs and the market value of unproved properties, impact the determination of the maximum carrying value of oil and natural gas properties.

During the year ended September 30, 2025, the Company incurred a non-cash ceiling test impairment for our U.S. oil and natural gas properties of $865,000. During the year ended September 30, 2024, the Company incurred a non-cash ceiling test impairment of $2,885,000, which included impairments for our U.S. and Canadian oil and natural gas properties of $721,000 and $2,164,000, respectively.

As discussed above, the ceiling test uses a 12-month historical rolling average first-day-of-the-month prices. As such, declines in the 12-month historical rolling average first-day-of-the-month prices used in our ceiling test calculation in future periods could result in impairment write-downs in future periods in the absence of any offsetting factors that are not currently known or projected. Based on the oil and gas prices for October 1, November 1 and December 1 of 2025, the oil prices used in the 12-month historical rolling first-day-of-the-month average for the ceiling test at December 31, 2025 are likely to be lower than at September 30, 2025. As such, we may incur a further impairment charge in the first quarter of fiscal 2026 ending December 31, 2025. The Company is currently unable to estimate a range of the amount of any potential future impairment write-downs as variables that impact the ceiling limitation are dependent upon actual results of activity through the end of December 2025.

*Foreign currency loss (gain)*

Foreign currency loss was $192,000 during the year ended September 30, 2025, as compared to a foreign currency gain of $10,000 during the year ended September 30, 2024, due to the effects of foreign exchange rate changes on intercompany loans and advances as a result of changes in the exchange rate between the U.S. dollar against the Canadian dollar. The foreign currency losses or gains from

------

intercompany balances are included in our Consolidated Statements of Operations as the intercompany balances were not considered long-term in nature because management estimates that these intercompany balances will be settled in the future.

*Loss on sale of assets*

On August 8, 2025, Barnwell entered into an agreement with an independent third party to sell all of its working interests in its U.S. oil and natural gas assets for a sales price of $2,300,000. The sales price per the agreement was adjusted for customary purchase price adjustments to reflect the economic activity from the effective date of July 1, 2025 to the closing date August 8, 2025. The Company recognized a loss on the sale of $636,000 before related income taxes in the year ended September 30, 2025.

*Equity in income of affiliates*

Barnwell's investment in the Kukio Resort Land Development Partnerships is accounted for using the equity method of accounting. Equity in income of affiliates was nil for the year ended September 30, 2025, as compared to equity in income of affiliates of $1,071,000 for the year ended September 30, 2024. The decrease in partnership income is primarily due to the Kukio Resort Land Development Partnerships' sale of the last two lots in Increment I in the prior year period, whereas there were no lots sold in the current year period.

No cash distributions were received during the year ended September 30, 2025. During the year ended September 30, 2024, Barnwell received cash distributions of $1,071,000 (resulting in a net amount of $953,000, after distributing $118,000 to non-controlling interests) from the Kukio Resort Land Development Partnerships.

In the quarter ended June 30, 2021, the Company received cumulative distributions from the Kukio Resort Land Development Partnerships in excess of our investment balance and in accordance with applicable accounting guidance, the Company suspended its equity method earnings recognition and the Kukio Resort Land Development Partnerships' investment balance was reduced to zero with the distributions received in excess of our investment balance recorded as equity in income of affiliates because the distributions are not refundable by agreement or by law and the Company is not liable for the obligations of or otherwise committed to provide financial support to the Kukio Resort Land Development Partnerships. The Company will record future equity method earnings only after our share of the Kukio Resort Land Development Partnerships' cumulative earnings in excess of distributions during the suspended period exceeds our share of the Kukio Resort Land Development Partnerships' income recognized for the excess distributions, and during this suspended period any distributions received will be recorded as equity in income of affiliates. Accordingly, no equity in income of affiliates was recognized in the year ended September 30, 2025.

Cumulative distributions received from the Kukio Resort Land Development Partnerships in excess of our investment balance was $106,000 at September 30, 2025 and $373,000 at September 30, 2024.

------

*Income taxes*

The components of loss from continuing operations before income taxes, after adjusting the loss for non-controlling interests, are as follows:

---

| | | |
|:---|:---|:---|
| | Year ended September 30, | Year ended September 30, |
| | **2025** | 2024 |
| United States | $**(5980000)** | $(1360000) |
| Canada | **(1064000)** | (2532000) |
|  | $**(7044000)** | $(3892000) |

---

Barnwell's effective consolidated income tax rate from continuing operations for fiscal 2025, after adjusting loss from continuing operations before income taxes for non-controlling interests, was (1)%, as compared to an effective consolidated income tax rate of (5)% for fiscal 2024.

Consolidated taxes do not bear a customary relationship to pretax results due primarily to the fact that the Company is taxed separately in Canada based on Canadian source operations and in the U.S. based on consolidated operations, and essentially all deferred tax assets, net of relevant offsetting deferred tax liabilities, are not estimated to have a future benefit as tax credits or deductions. The Company operates two subsidiaries in Canada, one of which is a U.S. corporation operating as a branch in Canada that is treated as a non-resident for Canadian tax purposes and thus has operating results that cannot be offset against or combined with the other Canadian subsidiary that files as a resident for Canadian tax purposes. Income from our non-controlling interest in the Kukio Resort Land Development Partnerships is treated as non-unitary for state of Hawaii unitary filing purposes, thus unitary Hawaii losses provide limited sheltering of such non-unitary income. Income from our investment in the Oklahoma oil venture is 100% allocable to Oklahoma. As such, Barnwell receives no benefit from consolidated or unitary losses and, therefore, is subject to Oklahoma state taxes. Our operations in Texas are subject to a franchise tax assessed by the state of Texas, however no significant amounts have been incurred to date.

On July 4, 2025, the President of the United States signed into law the One Big Beautiful Bill Act ("OBBBA"). The legislation, among other things, makes permanent, extends or modifies certain provisions under the 2017 Tax Cuts and Jobs Act, including a permanent extension of 100% bonus depreciation for certain capital expenditures. The Company has determined that there are no tax law changes in the OBBBA that significantly impact the Company's current and deferred income taxes.

*Net earnings attributable to non-controlling interests*

Earnings and losses attributable to non-controlling interests represent the non-controlling interests' share of revenues and expenses related to the various partnerships and joint ventures in which Barnwell has controlling interests and consolidates.

Net loss attributable to non-controlling interests totaled $8,000 in fiscal 2025, as compared to net earnings attributable to non-controlling interests of $234,000 in fiscal 2024. The $242,000 (103%) decrease is primarily due to decreases in the amount of equity in income of affiliates and percentage of sales revenue received in the current year period as compared to the same period in the prior year.

*Net earnings (loss) from discontinued operations*

Net earnings from discontinued operations was $12,000 during the year ended September 30, 2025, as compared to net loss from discontinued operation of $1,460,000 during the year ended September 30, 2024.

------

On March 14, 2025, the Company completed the sale of Water Resources, which represented the Company's contract drilling segment. The financial results of the Company's contract drilling business has been presented as discontinued operations in the consolidated financial statements for all periods presented. See Note 3 "Discontinued Operations" in the Notes to Consolidated Financial Statements in Item 8 of this report for further discussion and additional disclosures related to discontinued operations.

*Inflation*

The effect of inflation on Barnwell has generally been to increase its cost of operations, general and administrative costs and direct costs associated with oil and natural gas production and contract drilling operations. Oil and natural gas prices realized by Barnwell are essentially determined by world prices for oil and western Canadian/Midwestern U.S. prices for natural gas.

*Impact of Recently Issued Accounting Standards on Future Filings* 

In December 2023, the FASB issued ASU No. 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures", which requires disclosure of incremental income tax information within the tax rate reconciliation and expanded disclosures of income taxes paid both in the U.S. and foreign jurisdiction, among other disclosure requirements. This ASU is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this standard on Barnwell's consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03 "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses", which requires public companies to disclose specified information about certain costs and expenses in the notes to the financial statements at interim and annual reporting periods. This ASU is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this standard on Barnwell's consolidated financial statements.

**Liquidity and Capital Resources**

The Company has presented cash flows from discontinued operations in the accompanying Consolidated Statements of Cash Flows separately after the presentation of cash flows from operating, investing, and financing activities of continuing operations. See Note 3 "Discontinued Operations" in the Notes to Consolidated Financial Statements in Item 8 of this report for further discussion and additional disclosures related to discontinued operations. The focus of this section, "Liquidity and Capital Resources," is on the cash flows from continuing operations, which affects future liquidity and capital resources as the Company no longer has any significant continuing involvement with the discontinued operations after the sale.

At September 30, 2025, Barnwell had $504,000 in working capital. Barnwell's primary sources of liquidity are cash on hand and cash flow generated by our oil and natural gas operations, as cash flow from our land investment segment, if any, are expected to be intermittent and not significant to our liquidity.

------

*Cash Flows From Continuing Operations*

Cash flows used in operating activities totaled $1,773,000 for fiscal 2025, as compared to cash flows provided by operating activities of $5,334,000 for fiscal 2024. This $7,107,000 decrease in operating cash flows was primarily due to lower operating results for the oil and natural gas segment in the current year period as compared to the same period in the prior year, higher general and administrative expenses in the current year period due to the shareholder contests, and a distribution of income from the Kukio Resort Land Development Partnerships in the prior year period as compared to none in the current year period. The change was also due to the effect of changes in current assets and liabilities which was an increase of $2,100,000 in the prior year period as compared to $224,000 in the current year period.

Cash flows used in investing activities totaled $352,000 for fiscal 2025, as compared to cash flows used in investing activities of $2,819,000 for fiscal 2024. This $2,467,000 change in investing cash flows was due to an increase of $2,281,000 in proceeds from the sale of oil and natural gas assets and a decrease of $440,000 in cash paid for oil and natural gas capital expenditures in the current year period as compared to the same period in the prior year, partially offset by $439,000 of proceeds received by the land investment segment in the prior year period, as compared to none in the current year period.

Cash flows used in financing activities totaled $168,000 for fiscal 2025, as compared to cash flows used in financing activities of $226,000 for fiscal 2024. The $58,000 change in financing cash flows was due to a decrease of $226,000 in distributions to non-controlling interests, partially offset by $168,000 in repayments for insurance premium financing in the current year period as compared to none the same period in the prior year.

*Going Concern*

Our ability to sustain our business in the future will depend on sufficient oil and natural gas operating cash flows which are dependent on oil and natural gas prices, which can and in the past have fluctuated significantly, and on oil and natural gas operating expenses which are both variable and fixed. A sufficient level of oil and natural gas operating cash flows are necessary to fund discretionary oil and natural gas capital expenditures which must be economically successful to provide sufficient returns to grow reserves and production or at a minimum replace declining production from aging wells. Such a level of oil and natural gas capital expenditures will require funding from external debt and/or equity sources that are not currently in place, but those sources may not be feasible or sufficient. In addition, we will need sufficient cash flows to fund our non-discretionary outflows such as oil and natural gas asset retirement obligations, ongoing oil and natural gas operating expenses and general and administrative expenses, both those related to our oil and natural gas operations and those related to our being a public company.

In the quarters ended March 31, 2025 and June 30, 2025, continuing uncertainties regarding the sufficiency of our cash balances and future cash inflows due largely to a reduction in oil and natural gas prices and recent shareholder consent solicitation and proxy contest costs incurred, raised substantial doubt about our ability to meet our estimated cash outflows or continue as a going concern. However, due to the gross proceeds of $2,443,000 raised in the private placement offering in November 2025, management has determined that there is no longer substantial doubt regarding the Company's ability to continue as a going concern for one year from the filing of this Annual Report on Form 10-K.

*Oil and Natural Gas Capital Expenditures*

Barnwell's oil and natural gas capital expenditures, including accrued capital expenditures and acquisitions of oil and natural gas properties and excluding additions and revisions to estimated asset retirement obligations, decreased $3,866,000 from $4,805,000 in fiscal 2024 to $939,000 in fiscal 2025.

The Company did not drill or participate in the drilling of wells during the year ended September 30, 2025. In fiscal 2024, the Company participated in the drilling of one gross (1.0 net) operated development oil well in the Twining area. Capital expenditures incurred for the drilling of this well during the year ended September 30, 2024 totaled approximately $3,183,000.

*Oil and Natural Gas Property Dispositions* 

*Fiscal 2025*

On August 8, 2025, Barnwell entered into an agreement with an independent third party to sell all of its working interests in its U.S. oil and natural gas assets for a sales price of $2,300,000. The sales price per the agreement was adjusted for customary purchase price adjustments to reflect the economic activity from the effective date of July 1, 2025 to the closing date August 8, 2025. The Company recognized a loss on the sale of $636,000 before related income taxes in the year ended September 30, 2025. The U.S. oil and natural gas assets were located in the states of Texas and Oklahoma and were owned by wholly-owned subsidiaries of Barnwell. As a result of the sale, the Company no longer owns any oil and natural gas assets in the U.S., however, the Company will continue to explore for oil and natural gas opportunities in the U.S.

On August 28, 2025, Barnwell entered into and completed a purchase and sale agreement with an independent third party and sold its interests in certain oil and natural gas properties located in the Medicine River area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $288,000 in order to, among other things, reflect an economic closing date of September 30, 2025. The final determination of the customary adjustments to the purchase price has not yet been made; however, it is not expected to result in a material adjustment. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

*Fiscal 2024* 

In April 2024, Barnwell entered into and completed a purchase and sale agreement with an independent third party and sold its interests in certain oil and natural gas properties located in the Kaybob area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $441,000 in order to, among other things, reflect an economic effective date of May 1, 2024. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

In July 2024, Barnwell entered into and completed an agreement with an independent third party to convey interests in certain oil and natural gas properties located in the Bonanza and Balsam areas of Alberta, Canada. In consideration for the sale of the working interests in these properties, Barnwell retained a 4% overriding royalty on these properties and the buyer assumed the asset retirement obligations associated with these properties. There were no cash proceeds from the sale and no gain or loss was recognized on this conveyance as this did not result in a significant alteration of the relationship

------

between capitalized costs and proved reserves. With the disposition of the working interest, Barnwell reduced the full cost pool and abandonment liabilities associated with the working interests conveyed by approximately $153,000.

In September 2024, Barnwell entered into and completed a purchase and sale agreement with an independent third party and sold its interests in certain oil and natural gas properties located in the Wood River area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $292,000 in order to, among other things, reflect an economic effective closing date of September 30, 2024. From the sales proceeds, $38,000 was remitted directly to the Canada Revenue Agency by the buyers for potential amounts due for Barnwell's Canadian income taxes related to the sale. The proceeds from the sale was credited to our cash in October 2024 and is reflected in the Statement of Cash Flows for the year ended September 30, 2025. No gain or loss was recognized on this disposition as the sale proceeds were credited to the full cost pool and did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

*Asset Retirement Obligation*

In September 2019, the AER issued an abandonment/closure order for all wells and facilities in the Manyberries area which had been largely operated by LGX, an operating company that went into receivership in 2016. The estimated asset retirement obligation for the Company's interest in the wells and facilities in the Manyberries area is included in "Asset retirement obligation" in the Consolidated Balance Sheets.

After the abandonment/closure order was issued for Manyberries, the OWA created a WIP program for specific areas where there are a significant number of orphaned wells to abandon. The OWA has the ability and expertise to abandon wells using its internal resources and network of service providers resulting in efficiencies that companies such as Barnwell would not be able to obtain on its own. Under the WIP program, the Company would be required to provide payment for only Barnwell's working interest share, however, all WIP's would have to participate in the program for the OWA to begin its work. In March 2021, the Company was notified by the OWA that Barnwell's Manyberries wells were confirmed to be in the WIP program.

Under the agreement with the OWA, the Company was required to pay the abandonment and reclamation costs in advance through a cash deposit. Barnwell has provided $975,000 in cumulative cash deposits to the OWA since the program began in the fall of 2021, and any amount remaining after completion of the abandonments was to be refunded to the Company, and then upon commencement of the reclamation program a new deposit was to be made for those estimated costs. To date, the excess deposits that relate to abandonment work have not yet been refunded but have been used to fund the reclamation part of the program and the Company now estimates that a portion of the unused deposit will instead be applied to future reclamation work over the next several years. The estimated current portion of the unused deposit was $173,000 and $527,000 as of September 30, 2025 and 2024, respectively, and is included in "Other current assets" on the Company's Consolidated Balance Sheets. The non-current portion of the unused deposit of $222,000 along with $61,000 of non-current receivables at September 30, 2025, is included in "Other non-current assets" on the Company's Consolidated Balance Sheet at September 30, 2025.

*Private Placement Offering*

On November 24, 2025, the Company entered into a securities purchase agreement (the "Purchase Agreement") with certain investors (the "Purchasers"), including certain directors of the board of directors of the Company pursuant to which the Company agreed to issue and sell an aggregate of: (i) 2,221,141 shares of its common stock, par value $0.50 per share (the "Common Stock"), and (ii) warrants (the "Common Warrants") to purchase up to 1,029,104 shares of Common Stock (the "Warrant Shares") in a private placement offering of the Company's securities (the "Offering"). The directors of the Company participating as Purchasers in the Offering and certain other Purchasers did not receive any Common Warrants.

The price of the shares of Common Stock sold in the private placement was $1.10 per share of Common Stock. The Common Warrants have an exercise price of $1.65 per share.

The Offering closed on November 28, 2025 and the gross proceeds received from the Offering was approximately $2,443,000. The proceeds will be used for general corporate purposes. See Note 21 in the Notes to Consolidated Financial Statements in Item 8 of this report for additional disclosures related to the private placement offering.

*Report of Independent Registered Public Accounting Firm*

To the Board of Directors and Shareholders of

Barnwell Industries, Inc.

***Opinion on the Consolidated Financial Statements***

We have audited the accompanying consolidated balance sheets of Barnwell Industries, Inc. and subsidiaries (collectively, the Company) as of September 30, 2025 and 2024, and the related consolidated statements of operations, comprehensive loss, equity, and cash flows for each of the two years in the period ended September 30, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended September 30, 2025, in conformity with accounting principles generally accepted in the United States of America.

***Basis for Opinion***

These financial statements are the responsibility of the entity's management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

***Critical Audit Matters***

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters

------

does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

**Estimation of proved reserves impacting the recognition and valuation of depletion expense and**

**impairment of oil and gas properties**

Critical Accounting Matter Description

As described in Note 1 to the financial statements, the Company accounts for its oil and gas properties using the full cost method of accounting which requires management to make estimates of proved reserve volumes and future revenues and expenses to calculate depletion expense and measure its oil and gas properties for potential impairment. To estimate the volume of proved reserves and future revenues, management makes significant estimates and assumptions, including forecasting the production decline rate of producing properties. In addition, the estimation of proved reserves is also impacted by management's judgments and estimates regarding the financial performance of wells associated with proved reserves to determine if wells are expected, with reasonable certainty, to be economical under the appropriate pricing assumptions required in the estimation of depletion expense and potential impairment measurements. We identified the estimation of proved reserves of oil and gas properties, due to its impact on depletion expense and impairment evaluation, as a critical audit matter.

The principal consideration for our determination that the estimation of proved reserves is a critical audit matter is that changes in certain inputs and assumptions, which require a high degree of subjectivity necessary to estimate the volume and future revenues of the Company's proved reserves could have a significant impact on the measurement of depletion expense or the impairment assessment. In turn, auditing those inputs and assumptions required subjective and complex auditor judgement.

How the Critical Audit Matter was Addressed in the Audit

We obtained an understanding of the design and implementation of management's controls and our audit procedures related to the estimation of proved reserves included the following, among others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We evaluated the level of knowledge, skill, and ability of the Company's reservoir engineering specialists and their relationship to the Company, made inquiries of those reservoir engineers regarding the process followed and judgments made to estimate the Company's proved reserve volumes, and read the reserve report prepared by the Company's specialists.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To the extent key, sensitive inputs and assumptions used to determine proved reserve volumes and other cash flow inputs and assumptions are derived from Company's accounting records, such as commodity pricing, historical pricing differentials, operating costs, and working and net revenue interests, we tested management's process for determining the assumptions, including examining the underlying support, on a sample basis. Specifically, our audit procedures involved testing management's assumptions, to the extent key, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Compared the estimated pricing differentials used in the reserve report to realized prices related to revenue transactions recorded in the current year and examined contractual support for the pricing differentials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Evaluated the forecasted operating costs at year-end compared to historical operating costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Evaluated the working and net revenue interests used in the reserve report by inspecting a sample of ownership interests;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Applied analytical procedures to the reserve report by comparing to historical actual results and to the prior year reserve report.

We have served as the Company's auditor since 2020.

**<u>BARNWELL INDUSTRIES, INC.</u>**

**<u>AND SUBSIDIARIES</u>**

**<u>NOTES TO CONSOLIDATED FINANCIAL STATEMENTS</u>**

**<u>YEARS ENDED SEPTEMBER 30, 2025 AND 2024</u>**

**1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES</u>**

*Description of Business* 

Barnwell's continuing operations is engaged in the following lines of business: 1) acquiring, developing, producing and selling oil and natural gas in Canada and the U.S. and 2) leasehold land interests in Hawaii.

*Principles of Consolidation* 

The consolidated financial statements include the accounts of Barnwell Industries, Inc. and all majority-owned subsidiaries (collectively referred to herein as "Barnwell," "we," "our," "us," or the "Company"), including a 77.6%-owned land investment general partnership (Kaupulehu Developments) and a 75%-owned land investment partnership (KD Kona). All significant intercompany accounts and transactions have been eliminated.

Undivided interests in oil and natural gas exploration and production joint ventures are consolidated on a proportionate basis. Barnwell's investments in both unconsolidated entities in which a significant, but less than controlling, interest is held and in VIEs in which the Company is not deemed to be the primary beneficiary are accounted for by the equity method.

*Use of Estimates in the Preparation of Consolidated Financial Statements*

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management of Barnwell to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results could differ significantly from those estimates. Significant assumptions are required in the valuation of deferred tax assets, asset retirement obligations, and proved oil and natural gas reserves, and such assumptions may impact the amount at which such items are recorded.

*Discontinued Operations*

On March 14, 2025, the Company entered into and completed the sale of its wholly-owned subsidiary, Water Resources International, Inc. ("Water Resources"). Water Resources drills water wells and installs and repairs water pumping systems in Hawaii and represented our contract drilling segment. As a result of the sale, the Company has classified the related assets and liabilities and the results of its contract drilling business as discontinued operations in the consolidated financial statements for all periods presented. Prior to the sale, the Company did not have any assurances that a sale of Water Resources was likely to occur. See Note 3 "Discontinued Operations" for further discussion and additional disclosures related to discontinued operations. Unless otherwise noted, the discussions in the Notes to Consolidated Financial Statements refers to the Company's continuing operations.

------

*Revenue Recognition*

Barnwell operates in and derives revenue from the following two principal business segments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Oil and Natural Gas Segment* - Barnwell engages in oil and natural gas development, production, acquisitions and sales in Canada and the U.S.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Land Investment Segment* - Barnwell owns land interests in Hawaii.

*Oil and Natural Gas* - Barnwell's investments in oil and natural gas properties are located in Alberta, Canada. These property interests are principally held under governmental leases or licenses. Barnwell sells the large majority of its oil, natural gas and natural gas liquids production under short-term contracts between itself and marketers based on prices indexed to market prices and recognizes revenue at a point in time when the oil, natural gas and natural gas liquids are delivered, as this is where Barnwell's performance obligation is satisfied and title has passed to the customer. Barnwell's investments in oil and natural gas properties in Oklahoma and Texas were sold on August 8, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;*Land Investment* - Barnwell is entitled to receive contingent residual payments from the entities that previously purchased Barnwell's land investment interests under contracts entered into in prior years. The residual payments under those contracts become due when the entities sell lots and/or residential units in the areas that were previously sold under the aforementioned contracts or when a preferred payment threshold is achieved. The residual payments received by Barnwell are recognized as revenue when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur.

*Cash and Cash Equivalents*

Cash and cash equivalents include cash on hand and short-term investments with original maturities of three months or less.

*Concentration of Credit Risk* 

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. We maintain bank account balances with high quality financial institutions which often exceed insured limits. We have not experienced any losses with these accounts and believe that we are not exposed to any significant credit risk on cash.

*Accounts and Other Receivables*

Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for credit losses is Barnwell's best estimate of the amount of current expected credit losses in Barnwell's existing accounts receivable and is based on the aging of the receivable balances, analysis of historical credit loss rates, and current and future economic conditions affecting collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Barnwell does not have any off-balance sheet credit exposure related to its customers.

------

*Insurance Recoveries*

The Company maintains directors and officers liability insurance coverage. Receipts from insurance claim reimbursements under the liability coverage, up to the amount of costs recognized are considered recoveries. These recoveries are accounted for when they are probable of receipt. Insurance recoveries are not recognized prior to the recognition of the related costs incurred. Any insurance receivable for recoveries is recorded separately from the corresponding liability, and only if recovery is determined to be probable and reasonably estimable.

*Investments in Real Estate*

Barnwell accounts for sales of Increment I and Increment II leasehold land interests under the full accrual method. Gains from such sales were recognized when the buyer's investments were adequate to demonstrate a commitment to pay for the property, risks and rewards of ownership transferred to the buyer, and Barnwell did not have a substantial continuing involvement with the property sold. With regard to payments Kaupulehu Developments is entitled to receive from KD I and KD II, the percentage of sales payments from KD I and KD II and percentage of distributions from KD II are contingent future profits which will be recognized when they are realized. All costs of the sales of Increment I and Increment II leasehold land interests were recognized at the time of sale and were not deferred to future periods when any contingent profits will be recognized.

 *Variable Interest Entities*

The consolidation of VIEs is required when an enterprise has a controlling financial interest and is therefore the VIE's primary beneficiary. A controlling financial interest will have both of the following characteristics: (a) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The determination of whether an entity is a VIE and, if so, whether the Company is the primary beneficiary, may require significant judgment.

Barnwell analyzes its entities in which it has a variable interest to determine whether the entities are VIEs and, if so, whether the Company is the primary beneficiary. This analysis includes a qualitative review based on an evaluation of the design of the entity, its organizational structure, including decision making ability and financial agreements, as well as a quantitative review. Our unconsolidated affiliates that have been determined to be VIEs are accounted under the equity method because we do not have a controlling financial interest and are therefore not the VIE's primary beneficiary (see Note 6).

*Equity Method Investments*

Affiliated companies, which are limited partnerships or similar entities, in which Barnwell holds more than a 3% to 5% ownership interest and does not control, are accounted for as equity method investments. Equity method investment adjustments include Barnwell's proportionate share of investee income or loss, adjustments to recognize certain differences between Barnwell's carrying value and Barnwell's equity in net assets of the investee at the date of investment, impairments and other adjustments required by the equity method. Gains or losses are realized when such investments are sold. Barnwell classifies distributions received from equity method investments using the cumulative earnings approach in the Consolidated Statements of Cash Flows. Under the cumulative earnings approach, distributions received up to the amount of cumulative equity in earnings recognized are treated as returns

------

on investment and are classified within operating cash flows and those in excess of that amount are treated as returns of investment and are classified within investing cash flows.

Investments in equity method investees are evaluated for impairment as events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If the carrying amounts of the assets exceed their respective fair values, additional impairment tests are performed to measure the amounts of the impairment losses, if any. When an impairment test demonstrates that the fair value of an investment is less than its carrying value, management will determine whether the impairment is either temporary or other-than-temporary. Examples of factors which may be indicative of an other-than-temporary impairment include (a) the length of time and extent to which fair value has been less than carrying value, (b) the financial condition and near-term prospects of the investee, and (c) the intent and ability to retain the investment in the investee for a period of time sufficient to allow for any anticipated recovery in fair value. If the decline in fair value is determined by management to be other-than-temporary, the carrying value of the investment is written down to its estimated fair value as of the balance sheet date of the reporting period in which the assessment is made.

*Oil and Natural Gas Properties*

Barnwell uses the full cost method of accounting under which all costs incurred in the acquisition, exploration and development of oil and natural gas reserves, including costs related to unsuccessful wells and estimated future site restoration and abandonment, are capitalized. We capitalize internal costs that can be directly identified with our acquisition, exploration and development activities and do not include any costs related to production, general corporate overhead or similar activities.

The capitalized costs of oil and gas properties, excluding unevaluated and unproved properties, are amortized as depreciation, depletion and amortization expense using the units-of-production method based on estimated proved recoverable oil and gas reserves.

Costs associated with unevaluated and unproved properties, initially excluded from the amortization base, relate to unproved leasehold acreage, wells and production facilities in progress and wells pending determination of the existence of proved reserves. Unproved leasehold costs are transferred to the amortization base with the costs of drilling the related well once a determination of the existence of proved reserves has been made or upon impairment of a lease. Costs associated with wells in progress and completed wells that have yet to be evaluated are transferred to the amortization base once a determination is made whether or not proved reserves can be assigned to the property. Costs of dry wells are transferred to the amortization base immediately upon determination that the well is unsuccessful.

All items classified as unevaluated and unproved properties are assessed on a quarterly basis for possible impairment or reduction in value. Properties are assessed on an individual basis or as a group if properties are individually insignificant. The assessment includes consideration of various factors, including, but not limited to, the following: intent to drill; remaining lease term; geological and geophysical evaluations; drilling results and activity; assignment of proved reserves; and economic viability of development if proved reserves are assigned. During any period in which these factors indicate an impairment, the cumulative drilling costs incurred to date for such property and all or a portion of the associated leasehold costs are transferred to the full cost pool and become subject to amortization.

Under the full cost method of accounting, we review the carrying value of our oil and natural gas properties, on a country-by-country basis, each quarter in what is commonly referred to as the ceiling test. Under the ceiling test, capitalized costs, net of accumulated depletion and oil and natural gas related

------

deferred income taxes, may not exceed an amount equal to the sum of 1) the discounted present value (at 10%), using average first-day-of-the-month prices during the 12-month period ending as of the balance sheet date held constant over the life of the reserves (except where prices are defined by contractual arrangements), of Barnwell's estimated future net cash flows from estimated production of proved oil and natural gas reserves as determined by independent petroleum reserve engineers, less estimated future expenditures to be incurred in developing and producing the proved reserves but excluding future cash outflows associated with settling asset retirement obligations with the exception of those associated with proved undeveloped reserves from wells that are to be drilled in the future; plus 2) the cost of major development projects and unproven properties not subject to depletion, if any; plus 3) the lower of cost or estimated fair value of unproven properties included in costs subject to depletion; less 4) related income tax effects. If net capitalized costs exceed this limit, the excess is expensed. Depletion is computed using the units-of-production method whereby capitalized costs, net of estimated salvage values, plus estimated future costs to develop proved reserves and satisfy asset retirement obligations, are amortized over the total estimated proved reserves on a country-by-country basis. Investments in major development projects are not depleted until either proved reserves are associated with the projects or impairment has been determined. Proceeds from the disposition of oil and natural gas properties are credited to the full cost pool, with no gain or loss recognized, unless such a sale would significantly alter the relationship between capitalized costs and the proved reserves in a particular country.

Given the volatility of oil and gas prices, it is reasonably possible that the estimate of discounted future net cash flows from proved oil and gas reserves could change in the near term. If oil and gas prices decline in the future, even if only for a short period of time, it is possible that impairments of oil and gas properties could occur. In addition, it is reasonably possible that impairments could occur if costs are incurred in excess of any increases in the present value of future net cash flows from proved oil and gas reserves, or if properties are sold for proceeds less than the discounted present value of the related proved oil and gas reserves.

Barnwell's sales reflect its working interest share after royalties. Barnwell's production is generally delivered and sold at the plant gate. Barnwell does not have transportation volume commitments with pipelines and does not have natural gas imbalances related to natural gas balancing arrangements with its partners.

*Long-lived Assets* 

Long-lived assets to be held and used, other than oil and natural gas properties, are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Recoverability is measured by comparing the carrying amount of the asset to the future net cash flows expected to result from use of the asset (undiscounted and without interest charges). If it is determined that the asset may not be recoverable, impairment loss is measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of the asset carrying value or fair value, less cost to sell.

Other property and equipment is depreciated using the straight-line method based on estimated useful lives.

------

*Share-based Compensation*

Share-based compensation cost for Barnwell's equity-classified stock options, restricted stock units, and common stock issued for services is measured at fair value and is recognized as an expense over the requisite service period. For stock options, Barnwell utilizes a closed-form valuation model to determine the fair value of each option award. Expected volatilities are based on the historical volatility of Barnwell's stock over a period consistent with that of the expected terms of the options. The expected terms of the options represent expectations of future employee exercise and are estimated based on factors such as vesting periods, contractual expiration dates, historical trends in Barnwell's stock price, and historical exercise behavior. If the Company does not have sufficient historical data regarding employee exercise behavior, the "simplified method" as permitted by the SEC's Staff Accounting Bulletin No. 110, *Share-Based Payment* is utilized to estimate the expected terms of the options. The risk-free rates for periods within the contractual life of the options are based on the yields of U.S. Treasury instruments with terms comparable to the estimated option terms. Expected dividends are based on historical dividend payments. For restricted stock units, Barnwell utilizes the closing market price of the Company's common stock on the grant date reduced by the present value of the dividends expected to be paid on the underlying shares of common stock during the requisite service period (as these awards are not entitled to receive dividends until vested) to determine the fair value of each restricted stock unit award. For common stock issued for services, Barnwell utilizes the closing market price of the Company's common stock on the grant date to determine the fair value of the common stock issued for services. The Company's policy is to recognize forfeitures as they occur.

*Retirement Plans*

Barnwell accounts for its defined benefit pension plan and Supplemental Executive Retirement Plan by recognizing the over-funded or under-funded status as an asset or liability in its Consolidated Balance Sheets and recognizes changes in that funded status in the year in which the changes occur through comprehensive income. See further discussion at Note 9.

The estimation of Barnwell's retirement plan obligations, costs and liabilities requires management to estimate the amount and timing of cash outflows for projected future payments and cash inflows for maturities and expected returns on plan assets. These assumptions may have an effect on the amount and timing of future contributions.

At the end of each year, Barnwell determines the discount rate to be used to calculate the present value of plan liabilities and the net periodic benefit cost. The discount rate is an estimate of the current interest rate at which the retirement plan liabilities could be effectively settled at the end of the year. In estimating this rate, Barnwell performs a cash-flow matching discount rate analysis developed using high-quality corporate bonds yield. The discount rate used to value the future benefit obligation as of each year-end is the rate used to determine the periodic benefit cost in the following year.

The expected long-term return on assets assumption for the pension plans represents the average rate of return to be earned on plan assets over the period the benefits included in the benefit obligation are to be paid. The actual fair value of plan assets and estimated rate of return is used to determine the expected investment return during the year. The estimated rate of return on plan assets is based on an estimate of future experience for plan asset returns, the mix of plan assets, current market conditions, and expectations for future market conditions. A decrease (increase) of 50 basis points in the expected return on assets assumption would increase (decrease) pension expense by approximately $69,000 based on the assets of the plan at September 30, 2025.

------

The effects of changing assumptions are included in unamortized net gains and losses, which directly affect accumulated other comprehensive income. These unamortized gains and losses in excess of certain thresholds are amortized and reclassified to (loss) income over the average remaining service life of active employees.

*Asset Retirement Obligation*

Barnwell accounts for asset retirement obligations by recognizing the fair value of a liability for an asset retirement obligation in the period in which it is incurred if a reasonable estimate of fair value can be made. Barnwell estimates the fair value of asset retirement obligations based on the projected discounted future cash outflows required to settle abandonment and restoration liabilities. Such an estimate requires assumptions and judgments regarding the existence of liabilities, the amount and timing of cash outflows required to settle the liability, what constitutes adequate restoration, inflation factors, credit adjusted discount rates, and consideration of changes in legal, regulatory, environmental and political environments. Abandonment and restoration cost estimates are determined in conjunction with Barnwell's reserve engineers based on historical information regarding costs incurred to abandon and restore similar well sites, information regarding current market conditions and costs, and knowledge of subject well sites and properties. These assumptions represent Level 3 inputs.

Barnwell's estimated site restoration and abandonment costs of its oil and natural gas properties are capitalized as part of the carrying amount of oil and natural gas properties and depleted over the life of the related reserves. When the assumptions used to estimate a recorded asset retirement obligation change, a revision is recorded to both the asset retirement obligation and the capitalized cost of asset retirements. The liability is accreted at the end of each period through charges to oil and natural gas operating expense.

*Income Taxes*

Income taxes are determined using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax impacts of differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax asset will not be realized.

Management evaluates its potential exposures from tax positions taken that have been or could be challenged by taxing authorities. These potential exposures result because taxing authorities may take positions that differ from those taken by management in the interpretation and application of statutes, regulations and rules. Management considers the possibility of alternative outcomes based upon past experience, previous actions by taxing authorities (e.g., actions taken in other jurisdictions) and advice from tax experts. Recognized tax positions are initially and subsequently measured as the largest amount of tax benefit that is more likely than not of being realized upon ultimate settlement with a taxing authority on a jurisdiction-by-jurisdiction basis. Liabilities for unrecognized tax benefits related to such tax positions are included in long-term liabilities unless the tax position is expected to be settled within the upcoming year, in which case the liabilities are included in current liabilities. Interest and penalties related to uncertain tax positions are included in income tax expense.

------

Our operations in Texas are subject to a franchise tax assessed by the state of Texas which is presented as income tax expense.

*Environmental*

Barnwell is subject to extensive environmental laws and regulations. These laws, which are constantly changing, regulate the discharge of materials into the environment and maintenance of surface conditions and may require Barnwell to remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed. Liabilities for expenditures of a noncapital nature are recorded when environmental assessment and/or remediation is probable, and the costs can be reasonably estimated.

Barnwell recognizes an insurance receivable related to environmental expenditures when collection of the receivable is deemed probable. Any recognition of an insurance receivable is recorded by crediting and offsetting the original charge. Any differential arising between insurance recoveries and insurance receivables is expensed or capitalized, consistent with the original treatment.

*Derivative Instruments*

Barnwell may utilize physical forward commodity contracts to mitigate market price risk on its oil and natural gas output when deemed appropriate. Purchase and sale contracts with a fixed price determined at inception are recorded on the Consolidated Balance Sheets as derivative financial instruments if such contracts are readily convertible to cash - unless the contracts are eligible for and elected as the normal purchases and normal sales exception ("NPNS"); in which case, the contracts are recorded on an accrual basis and the Company recognizes the amounts relating to such transactions during the period when the commodities are physically delivered. The Company generally applies the NPNS exception to eligible oil and natural gas contracts to purchase or sell quantities it expects to use or sell in the normal course of business. The Company has not traded in any derivative contracts other than where the NPNS exception is applied, and it does not apply hedge accounting.

*Foreign Currency Translations and Transactions*

Assets and liabilities of foreign subsidiaries are translated at the year-end exchange rate. Operating results of foreign subsidiaries are translated at average exchange rates during the period. Translation adjustments have no effect on net income and are included in "Accumulated other comprehensive income, net" in the accompanying Consolidated Balance Sheets.

Foreign currency gains or losses on intercompany loans and advances that are not considered long-term investments in nature because management intends to settle these intercompany balances in the future are included in our statements of operations.

------

*Fair Value Measurements*

Fair value is defined as the amount that would be received from the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following categories:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities in active markets and have the highest priority.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3: Unobservable inputs for the financial asset or liability and have the lowest priority.

*Recently Adopted Accounting Pronouncements*

In November 2023, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which expands reportable segment disclosure requirements on an annual and interim basis, primarily through enhanced disclosures about significant segment expenses. The Company adopted the provisions of this ASU in the annual reporting period for fiscal year ended September 30, 2025. The adoption of this update did not have an impact on Barnwell's consolidated financial statements.

**2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>GOING CONCERN</u>**

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of these consolidated financial statements.

Our ability to sustain our business in the future will depend on sufficient oil and natural gas operating cash flows which are dependent on oil and natural gas prices, which can and in the past have fluctuated significantly, and on oil and natural gas operating expenses which are both variable and fixed. A sufficient level of oil and natural gas operating cash flows are necessary to fund discretionary oil and natural gas capital expenditures which must be economically successful to provide sufficient returns to grow reserves and production or at a minimum replace declining production from aging wells. Such a level of oil and natural gas capital expenditures will require funding from external debt and/or equity sources that are not currently in place, but those sources may not be feasible or sufficient. In addition, we will need sufficient cash flows to fund our non-discretionary outflows such as oil and natural gas asset retirement obligations, ongoing oil and natural gas operating expenses and general and administrative expenses, both those related to our oil and natural gas operations and those related to our being a public company.

In the quarters ended March 31, 2025 and June 30, 2025, continuing uncertainties regarding the sufficiency of our cash balances and future cash inflows due largely to a reduction in oil and natural gas prices and recent shareholder consent solicitation and proxy contest costs incurred, raised substantial doubt about our ability to meet our estimated cash outflows or continue as a going concern. However, due to the gross proceeds of $2,443,000 raised in the private placement offering in November 2025,

------

management has determined that there is no longer substantial doubt regarding the Company's ability to continue as a going concern for one year from the filing of this Annual Report on Form 10-K.

**3.&nbsp;&nbsp;&nbsp;&nbsp;<u>DISCONTINUED OPERATIONS</u>**

*Sale of Water Resources*

On March 14, 2025, the Company entered into a Stock Purchase Agreement with three unrelated individuals (collectively, the "Buyer") whereby the Buyer acquired all of the shares of capital stock of Water Resources (the "Shares") owned by the Company (the "Purchase Agreement"). The sale and purchase of the Shares closed (the "Closing") simultaneously with the execution and delivery of the Purchase Agreement by each of the parties thereto on March 14, 2025. The aggregate purchase price for the Shares was $1,050,000, which was paid at Closing by the Buyer as follows: an initial aggregate cash payment of $250,000 and the delivery of a non-interest bearing promissory note with a principal amount of $800,000 (the "Promissory Note"). The principal payments on the Promissory Note were to be paid in installments on the following schedule: $200,000 on May 15, 2025; and $150,000 on June 16, 2025, July 15, 2025, August 15, 2025, and September 15, 2025. The Promissory Note is secured by certain specified assets of Water Resources and personal guarantees of the purchasers.

In August 2025, the Promissory Note was amended to the following schedule: $100,000 on December 15, 2025; $50,000 on February 15, 2026; and $150,000 on March 15, 2026 and to increase the annual interest rate on the Promissory Note from zero to 12% beginning August 15, 2025 and to 18% beginning December 15, 2025. As of September 30, 2025, the balance of the Promissory Note was $300,000 and is presented as "Note receivable" on the Consolidated Balance Sheets.

Water Resources drills water wells and installs and repairs water pumping systems in Hawaii and represented our contract drilling segment. As a result of the sale, the Company has classified the related assets and liabilities and the results of its contract drilling business as discontinued operations in the consolidated financial statements for all periods presented. Prior to the sale, the Company did not have any assurances that a sale of Water Resources was likely to occur. The Company recorded a loss of $193,000 on the sale of Water Resources, which was included in the results from discontinued operations for the year ended September 30, 2025. There was no impact from the sale of Water Resources on the provision for income taxes.

Basic loss per share is computed using the weighted-average number of common shares outstanding for the period. Diluted loss per share is calculated using the treasury stock method to reflect the assumed issuance of common shares for all potentially dilutive securities, which consist of outstanding stock options and nonvested restricted stock units. Potentially dilutive shares are excluded from the computation of diluted loss per share if their effect is anti-dilutive.

Options to purchase 454,452 shares of common stock and 218,300 restricted stock units were excluded from the computation of diluted shares for the year ended September 30, 2025, as their inclusion would have been anti-dilutive. Options to purchase 465,000 shares of common stock and 98,795 restricted stock units were excluded from the computation of diluted shares for the year ended September 30, 2024, as their inclusion would have been anti-dilutive.

*Insurance Recovery Receivable*

In the quarter ended June 30, 2025, the Company filed an insurance claim for $348,000 with our insurance carrier for the reimbursement of certain legal fees incurred that are covered under our directors and officers' liability insurance policies. Accordingly, the Company determined that an insurance recovery from our insurance carrier was probable and reasonably estimable and therefore recorded an estimated accrued insurance recovery receivable of $348,000 at June 30, 2025 and no subsequent revision to the accrual has been recorded as of September 30, 2025. The insurance recovery receivable is included in "Accounts and other receivables, net of allowance for credit losses," in the accompanying Consolidated Balance Sheet and the related legal expense recovery was recorded in "General and administrative" expenses in the accompanying Consolidated Statements of Operations.

The estimated accrued insurance recovery receivable amount is management's best estimate of the probable recoverable amount under the insurance policies. While the insurer has confirmed that certain costs incurred by the Company are eligible for claim under the Company's insurance policies, the amount ultimately recoverable through insurance is dependent upon the insurer's completion of their review of eligible legal costs incurred and the recoverable amount may differ from management's estimate.

*Investment in Kukio Resort Land Development Partnerships*

On November 27, 2013, Barnwell, through a wholly-owned subsidiary, entered into two limited liability limited partnerships, KD Kona and KKM, and indirectly acquired a 19.6% non-controlling ownership interest in each of KD Kukio Resorts, KD Maniniowali, and KDK for $5,140,000. The Kukio Resort Land Development Partnerships own certain real estate and development rights interests in the Kukio, Maniniowali and Kaupulehu portions of Kukio Resort, a private residential community on the Kona coast of the island of Hawaii, as well as Kukio Resort's real estate sales office operations. KDK holds interests in KD I and KD II. KD I is the developer of Increment I and KD II is the developer of Increment II. Barnwell's ownership interests in the Kukio Resort Land Development Partnerships is accounted for using the equity method of accounting.

In March 2019, KD II admitted a new development partner, Replay, a party unrelated to Barnwell, in an effort to move forward with development of the remainder of Increment II at Kaupulehu. KDK and Replay hold ownership interests of 55% and 45%, respectively, of KD II and Barnwell has a 10.8% indirect non-controlling ownership interest in KD II through KDK, which is accounted for using the equity method of accounting. Barnwell continues to have an indirect 19.6% non-controlling ownership interest in KD Kukio Resorts, KD Maniniowali, and KD I.

The partnerships derive income from the sale of residential parcels in Increment I, which is now completely sold, as well as from commissions on real estate resales by the real estate sales office and revenues resulting from the sale of a few remaining private club memberships. The last two remaining single-family lots of the 80 lots developed within Increment I were sold in the quarter ended March 31, 2024.

Increment II is not yet under development, and there is no assurance that development of such acreage will in fact occur. No definitive development plans have been made by KD II, the developer of Increment II, as of the date of this report.

In November 2025, Kaupulehu Developments entered into an agreement with Mr. David Johnston, the son of Mr. Terry Johnston, a partner in Kaupulehu Developments, to surrender any and all remaining rights for Increment II for $2,000,000 of which $70,000 was received. Additionally, the purchaser has the right to extend the closing by up to two years by making a $70,000 payment in each of the next two years,

------

with those payments applied against the $2,000,000 purchase price. The closing of this transaction is entirely dependent on the purchaser and therefore may not happen.

Subsequent to fiscal 2025, pursuant to a unit purchase agreement KDK, of which Barnwell holds a 19.6% interest, agreed to sell KDK's interests in Increment II to Mr. David Johnston for $2,109,000. The unit purchase agreement is subject to due diligence, and there is no certainty that the transaction will close. Furthermore, there is also no assurance on the timing or amounts that the general partner of KDK would distribute upon a closing.

Barnwell has the right to receive distributions from the Kukio Resort Land Development Partnerships via its non-controlling interests in KD Kona and KKM, based on its respective partnership sharing ratios of 75% and 34.45%, respectively. No cash distributions were received during the year ended September 30, 2025. During the year ended September 30, 2024, Barnwell received cash distributions of $1,071,000 (resulting in a net amount of $953,000, after distributing $118,000 to non-controlling interests) from the Kukio Resort Land Development Partnerships.

Equity in income of affiliates was nil for the year ended September 30, 2025, as compared to equity in income of affiliates of $1,071,000 for the year ended September 30, 2024.

Summarized financial information for the Kukio Resort Land Development Partnerships is as follows:

---

| | | |
|:---|:---|:---|
| | Year ended September 30, | Year ended September 30, |
| | **2025** | 2024 |
| Revenue | $**7236000** | $13555000 |
| Gross profit | $**3234000** | $8651000 |
| Net earnings | $**1208000** | $6437000 |

---

In the quarter ended June 30, 2021, the Company received cumulative distributions from the Kukio Resort Land Development Partnerships in excess of our investment balance and in accordance with applicable accounting guidance, the Company suspended its equity method earnings recognition and the Kukio Resort Land Development Partnerships' investment balance was reduced to zero with the distributions received in excess of our investment balance recorded as equity in income of affiliates because the distributions are not refundable by agreement or by law and the Company is not liable for the obligations of or otherwise committed to provide financial support to the Kukio Resort Land Development Partnerships. The Company will record future equity method earnings only after our share of the Kukio Resort Land Development Partnerships' cumulative earnings in excess of distributions during the suspended period exceeds our share of the Kukio Resort Land Development Partnerships' income recognized for the excess distributions, and during this suspended period any distributions received will be recorded as equity in income of affiliates. Accordingly, no equity in income of affiliates was recognized in the year ended September 30, 2025.

Cumulative distributions received from the Kukio Resort Land Development Partnerships in excess of our investment balance was $106,000 at September 30, 2025 and $373,000 at September 30, 2024.

*Sale of Interest in Leasehold Land* 

Kaupulehu Developments holds rights to receive payments from KD I and KD II resulting from the sale of lots and/or residential units within Increment I, which is now fully sold, and within Increment II, which is not yet developed (see Note 20).

With respect to Increment I, Kaupulehu Developments was entitled to receive payments from KD I based on 10% of the gross receipts from KD I's sales of single-family residential lots in Increment I. The last two single-family lots of the 80 lots developed within Increment I were sold in the quarter ended March 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;Under the terms of the Increment II agreement with KD II, Kaupulehu Developments is entitled to 15% of the distributions of KD II, the cost of which is to be solely borne by KDK out of its 55% ownership interest in KD II, plus a priority payout of 10% of KDK's cumulative net profits derived from Increment II sales subsequent to Phase 2A, up to a maximum of $3,000,000 as to the priority payout. Such interests are limited to distributions or net profits interests and Barnwell does not have any partnership interests in KD II or KDK through its interest in Kaupulehu Developments. The arrangement also gives Barnwell rights to three single-family residential lots in Phase 2A of Increment II, and four single-family residential lots in phases subsequent to Phase 2A when such lots are developed by KD II, all at no cost to Barnwell. Barnwell is committed to commence construction of improvements within 90 days of the transfer of the four lots in the phases subsequent to Phase 2A as a condition of the transfer of such lots. Also, in addition to Barnwell's existing obligations to pay professional fees to certain parties based on percentages of its gross receipts, Kaupulehu Developments is obligated to pay an amount equal to 0.72% and 0.20% of the cumulative net profits of KD II to KD Development and a pool of various individuals, respectively, all of whom are partners of KKM and are unrelated to Barnwell, in compensation for the agreement of these parties to admit the new development partner for Increment II. Such compensation will be reflected as the obligation becomes probable and the amount of the obligation can be reasonably estimated.

The following table summarizes the Increment I revenues from KD I and the amount of fees directly related to such revenues (see Note 18 "Commitments and Contingencies - Other Matters"):

There is no assurance with regards to the amounts of future payments from Increment II to be received or that the remaining acreage within Increment II will be developed. No definitive development plans have been made by KD II, the developer of Increment II, as of the date of this report.

*Investment in Leasehold Land Interest – Lot 4C*

Kaupulehu Developments holds an interest in an area of approximately 1,000 acres of vacant leasehold land zoned conservation located adjacent to Lot 4A, which currently has no development potential without both a development agreement with the lessor and zoning reclassification. The lease terminates in December 2025.

*Fiscal 2025 Oil and Natural Gas Property Dispositions* 

On August 8, 2025, Barnwell entered into an agreement with an independent third party to sell all of its working interests in its U.S. oil and natural gas assets for a sales price of $2,300,000. The sales price per the agreement was adjusted for customary purchase price adjustments to reflect the economic activity from the effective date of July 1, 2025 to the closing date August 8, 2025. The Company recognized a loss on the sale of $636,000 before related income taxes in the year ended September 30, 2025. The U.S. oil and natural gas assets were located in the states of Texas and Oklahoma and were owned by wholly-owned subsidiaries of Barnwell. As a result of the sale, the Company no longer owns any oil and natural gas assets in the U.S., however, the Company will continue to explore for oil and natural gas opportunities in the U.S.

On August 28, 2025, Barnwell entered into and completed a purchase and sale agreement with an independent third party and sold its interests in certain oil and natural gas properties located in the Medicine River area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $288,000 in order to, among other things, reflect an economic closing date of September 30, 2025. The final determination of the customary adjustments to the purchase price has not yet been made; however, it is not expected to result in a material adjustment. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

*Fiscal 2024 Oil and Natural Gas Property Dispositions*

In April 2024, Barnwell entered into and completed a purchase and sale agreement with an independent third party and sold its interests in certain oil and natural gas properties located in the Kaybob area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $441,000 in order to, among other things, reflect an economic effective date of May 1, 2024. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

In July 2024, Barnwell entered into and completed an agreement with an independent third party to convey interests in certain oil and natural gas properties located in the Bonanza and Balsam areas of Alberta, Canada. In consideration for the sale of the working interests in these properties, Barnwell retained a 4% overriding royalty on these properties and the buyer assumed the asset retirement obligations associated with these properties. There were no cash proceeds from the sale and no gain or loss was recognized on this conveyance as this did not result in a significant alteration of the relationship between capitalized costs and proved reserves. With the disposition of the working interest, Barnwell reduced the full cost pool and abandonment liabilities associated with the working interests conveyed by approximately $153,000.

------

In September 2024, Barnwell entered into and completed a purchase and sale agreement with an independent third party and sold its interests in certain oil and natural gas properties located in the Wood River area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $292,000 in order to, among other things, reflect an economic effective closing date of September 30, 2024. From the sales proceeds, $38,000 was remitted directly to the Canada Revenue Agency by the buyers for potential amounts due for Barnwell's Canadian income taxes related to the sale. The proceeds from the sale was credited to our cash in October 2024 and is reflected in the Statement of Cash Flows for the year ended September 30, 2025. No gain or loss was recognized on this disposition as the sale proceeds were credited to the full cost pool and did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

*Impairment of Oil and Natural Gas Properties*

Under the full cost method of accounting, the Company performs quarterly oil and natural gas ceiling test calculations. Changes in the 12-month rolling average first-day-of-the-month prices for oil, natural gas and natural gas liquids prices (except where prices are defined by contractual arrangements), the value of reserve additions as compared to the amount of capital expenditures to obtain them, and changes in production rates and estimated levels of reserves, future development costs and the market value of unproved properties, impact the determination of the maximum carrying value of oil and natural gas properties.

During the year ended September 30, 2025, the Company incurred a non-cash ceiling test impairment for our U.S. oil and natural gas properties of $865,000. During the year ended September 30, 2024, the Company incurred a non-cash ceiling test impairment of $2,885,000, which included impairments for our U.S. and Canadian oil and natural gas properties of $721,000 and $2,164,000, respectively.

As discussed above, the ceiling test uses a 12-month historical rolling average first-day-of-the-month prices. As such, declines in the 12-month historical rolling average first-day-of-the-month prices used in our ceiling test calculation in future periods could result in impairment write-downs in future periods in the absence of any offsetting factors that are not currently known or projected. Based on the oil and gas prices for October 1, November 1 and December 1 of 2025, the oil prices used in the 12-month historical rolling first-day-of-the-month average for the ceiling test at December 31, 2025 are likely to be lower than at September 30, 2025. As such, we may incur a further impairment charge in the first quarter of fiscal 2026 ending December 31, 2025. The Company is currently unable to estimate a range of the amount of any potential future impairment write-downs as variables that impact the ceiling limitation are dependent upon actual results of activity through the end of December 2025.

Asset retirement obligations were reduced by $209,000 and $442,000 in fiscal 2025 and 2024, respectively, for those obligations that were assumed by purchasers of Barnwell's oil and natural gas properties (see Note 7 for additional details on dispositions). Asset retirement obligations were also reduced by $694,000 and $614,000 in fiscal 2025 and 2024, respectively, primarily due to revisions related to the estimated timing of future abandonments. Asset retirement obligations also increased by nil and $37,000 in fiscal 2025 and 2024, respectively, due primarily to our wells drilled and acquisitions. The asset retirement obligation reflects the estimated present value of the amount of dismantlement, removal, site reclamation, and similar activities associated with Barnwell's oil and natural gas properties. Barnwell estimates the ultimate productive life of the properties, a credit-adjusted risk-free rate, and an inflation factor in order to determine the current present value of this obligation. The credit-adjusted risk-free rate for the entire asset retirement obligation is a blended rate which ranges from 6% to 13.5%.

In September 2019, the AER issued an abandonment/closure order for all wells and facilities in the Manyberries area which had been largely operated by LGX, an operating company that went into receivership in 2016. The estimated asset retirement obligation for the Company's interest in the wells and facilities in the Manyberries area is included in "Asset retirement obligation" in the Consolidated Balance Sheets.

After the abandonment/closure order was issued for Manyberries, the OWA created a WIP program for specific areas where there are a significant number of orphaned wells to abandon. The OWA has the ability and expertise to abandon wells using its internal resources and network of service providers resulting in efficiencies that companies such as Barnwell would not be able to obtain on its own. Under the WIP program, the Company would be required to provide payment for only Barnwell's working interest share, however, all WIP's would have to participate in the program for the OWA to begin its work. In March 2021, the Company was notified by the OWA that Barnwell's Manyberries wells were confirmed to be in the WIP program.

Under the agreement with the OWA, the Company was required to pay the abandonment and reclamation costs in advance through a cash deposit. Barnwell has provided $975,000 in cumulative cash deposits to the OWA since the program began in the fall of 2021, and any amount remaining after

------

completion of the abandonments was to be refunded to the Company, and then upon commencement of the reclamation program a new deposit was to be made for those estimated costs. To date, the excess deposits that relate to abandonment work have not yet been refunded but have been used to fund the reclamation part of the program and the Company now estimates that a portion of the unused deposit will instead be applied to future reclamation work over the next several years. The estimated current portion of the unused deposit was $173,000 and $527,000 as of September 30, 2025 and 2024, respectively, and is included in "Other current assets" on the Company's Consolidated Balance Sheets. The non-current portion of the unused deposit of $222,000 along with $61,000 of non-current receivables at September 30, 2025, is included in "Other non-current assets" on the Company's Consolidated Balance Sheet at September 30, 2025.

Barnwell sponsors a noncontributory defined benefit pension plan ("Pension Plan") covering substantially all of its U.S. employees, with benefits based on years of service and the employee's highest consecutive 5 years average earnings. Barnwell's funding policy is intended to provide for both benefits attributed to service to date and for those expected to be earned in the future. In addition, Barnwell sponsors a Supplemental Executive Retirement Plan ("SERP"), a noncontributory supplemental retirement benefit plan which covers certain current and former employees of Barnwell for amounts exceeding the limits allowed under the Pension Plan. Effective December 31, 2019, the accrual of benefits for all participants in the Pension Plan and SERP was frozen and the plans were closed to new participants from that point forward.

The following tables detail the changes in benefit obligations, fair values of plan assets and reconciliations of the funded status of the retirement plans:

The accumulated benefit obligation for the Pension Plan was $8,101,000 and $8,195,000 at September 30, 2025 and 2024, respectively. The accumulated benefit obligation for the SERP was $2,061,000 and $1,974,000 at September 30, 2025 and 2024, respectively. The accumulated benefit obligations are the same as the projected benefit obligations due to the Pension Plan and SERP being frozen as of December 31, 2019.

Currently, no contributions are planned to be made to the Pension Plan during fiscal 2026. The SERP plan is unfunded and Barnwell funds benefits when payments are made. Expected payments under the SERP for fiscal 2026 are expected to be $270,000. Fluctuations in actual market returns as well as changes in general interest rates will result in changes in the market value of plan assets and may result in increased or decreased retirement benefits costs and contributions in future periods.

The Pension Plan actuarial gains in fiscal 2025 were primarily due to an increase in the discount rate and actual investment returns that were greater than the assumed rate of return. The SERP actuarial gains in fiscal 2025 were primarily due to an increase in the discount rate.

The Pension Plan actuarial losses in fiscal 2024 were primarily due to a decrease in the discount rate, partially offset by an actuarial gain resulting from actual investment returns that were greater than the assumed rate of return. The SERP actuarial losses in fiscal 2024 were primarily due to a decrease in the discount rate.

*Plan Assets*

The trustees of the Pension Plan communicate periodically with the Pension Plan's professional investment advisors to establish investment policies, direct investments and select investment options. The overall investment objective of the Pension Plan is to attain a diversified combination of investments that provides long-term growth in the assets of the plan to fund future benefit obligations while managing risk

------

in order to meet current benefit obligations. Generally, interest and dividends received provide cash flows to fund current benefit obligations. Longer-term obligations are generally estimated to be provided for by growth in equity securities. The Pension Plan's investment policy permits investments in a diversified mix of U.S. and international equities, fixed income securities, other investments, and cash equivalents.

The Pension Plan's investments in fixed income securities include preferred securities and corporate bonds. The Pension Plan's investments in equity securities primarily include domestic companies and is comprised of companies with market capitalization categorized as follows: 61% micro-cap; 22% small-cap; 8% mid-cap; and 9% large-cap. The Pension Plan's other investment is a note receivable from an unrelated private company.

A portion of the Pension Plan's investments is in publicly traded stocks, one of which is Barnwell's common stock. As of September 30, 2025 and 2024, the Pension Plan held 666,077 and 413,148 shares, respectively, of Barnwell common stock (see Note 20 for additional details).

The Company's year-end target allocation, by asset category, and the actual asset allocations were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | Target | September 30, | September 30, |
| Asset Category | Allocation | 2025 | 2024 |
| Cash and cash equivalents | 0% - 25% | 1% | 4% |
| Fixed income securities | 15% - 40% | 15% | 19% |
| Equity securities | 45% - 75% | 80% | 73% |
| Other investment | 0% - 10% | 4% | 4% |

---

Actual investment allocations may vary from our target allocations from time to time due to prevailing market conditions. The trustees periodically review our actual investment allocations and rebalance our investments to our target allocations as dictated by current and anticipated market conditions and required cash flows.

We categorize plan assets into three levels based upon the assumptions used to price the assets. Level 1 provides the most reliable measure of fair value, whereas Level 3 requires significant management judgment in determining the fair value. Equity securities and exchange-traded funds are valued by obtaining quoted prices on recognized and highly liquid exchanges. Fixed income securities are valued based upon the closing price reported in the active market in which the security is traded. All of our plan assets, except for the note receivable from a private company, are categorized as Level 1 assets, and as such, the actual market value is used to determine the fair value of assets. The fair value of the note receivable from an unrelated private company is valued based upon the terms of the note receivable's agreement and unobservable inputs such as management's consideration of the counterparty's credit risk and as such, is categorized as a Level 3 asset.

The following tables set forth by level, within the fair value hierarchy, pension plan assets at their fair value:

Consolidated taxes do not bear a customary relationship to pretax results due primarily to the fact that the Company is taxed separately in Canada based on Canadian source operations and in the U.S. based on consolidated operations, and essentially all deferred tax assets, net of relevant offsetting deferred tax liabilities, are not estimated to have a future benefit as tax credits or deductions. The Company operates two subsidiaries in Canada, one of which is a U.S. corporation operating as a branch in Canada that is treated as a non-resident for Canadian tax purposes and thus has operating results that cannot be offset against or combined with the other Canadian subsidiary that files as a resident for Canadian tax purposes. Income from our non-controlling interest in the Kukio Resort Land Development Partnerships is treated as non-unitary for state of Hawaii unitary filing purposes, thus unitary Hawaii losses provide limited sheltering of such non-unitary income. Income from our investment in the Oklahoma oil venture is 100% allocable to Oklahoma. As such, Barnwell receives no benefit from consolidated or unitary losses and, therefore, is subject to Oklahoma state taxes. Our operations in Texas are subject to a franchise tax assessed by the state of Texas, however no significant amounts have been incurred to date.

On July 4, 2025, the President of the United States signed into law the One Big Beautiful Bill Act ("OBBBA"). The legislation, among other things, makes permanent, extends or modifies certain provisions under the 2017 Tax Cuts and Jobs Act, including a permanent extension of 100% bonus depreciation for certain capital expenditures. The Company has determined that there are no tax law changes in the OBBBA that significantly impact the Company's current and deferred income taxes.

------

A reconciliation between the reported income tax expense and the amount computed by multiplying the loss attributable to Barnwell before income taxes by the U.S. federal tax rate of 21% is as follows:

---

| | | |
|:---|:---|:---|
| | Year ended September 30, | Year ended September 30, |
| | **2025** | 2024 |
| Tax benefit computed by applying statutory rate | $**(1477000)** | $(1124000) |
| Increase in the valuation allowance | **1426000** | 1383000 |
| Additional effect of the foreign tax provision on the total tax provision | **(28000)** | (129000) |

| Other | **168000** | 25000 |
|  | $**71000** | $213000 |

The change in the valuation allowance shown in the table above excludes the impact of changes in the valuation allowance of items that are incorporated within the respective reconciliation line items elsewhere in the table.

The total valuation allowance decreased $1,505,000 for the year ended September 30, 2025. The decrease was due to current fiscal year operational activity that resulted in changes in deferred tax asset and liability balances, and there were no changes in judgment about the realizability of related deferred tax assets in future years. Of the total net decrease in the valuation allowance for fiscal 2025, $1,354,000 was recognized as an income tax benefit and $151,000 was credited to accumulated other comprehensive income.

Net deferred tax assets at September 30, 2025 of $3,823,000 consists of the portion of deferred tax assets that are estimated to be partially realized through corresponding concurrent reversals of deferred tax liabilities related to the Kukio Resort Land Development Partnerships' excess of book income over taxable income, foreign branch deferred taxes, asset for retirement benefits accrued for books but not for tax under U.S. tax law, and certain other minor deferred tax liabilities.

At September 30, 2025, Barnwell had U.S. federal net operating loss carryovers, U.S. state net operating loss carryovers and Canadian net operating loss carryovers totaling $45,063,000, $7,565,000 and $5,551,000, respectively. The U.S. federal net operating loss carryovers generated through September 30, 2018 expire in fiscal years 2032-2038, the U.S. state unitary net operating loss carryovers generated through September 30, 2017 expire in fiscal years 2033-2037, and the Canadian net operating loss carryovers expire in fiscal years 2039-2045. The U.S. federal net operating loss carryovers generated in fiscal years 2019-2025 and the U.S. state net operating loss carryovers generated in fiscal years 2018-2025 have no expiry, however utilization of the U.S. state and U.S. federal net operating loss carryovers generated in these and future years are limited to 80% of taxable income.

FASB ASC Topic 740, Income Taxes, prescribes a threshold for recognizing the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination by a taxing authority.

Barnwell files U.S. federal income tax returns, income tax returns in various U.S. states, and Canadian federal and provincial tax returns. A number of years may elapse before an uncertain tax position, for which we have unrecognized tax benefits, is audited and finally resolved. We believe that our unrecognized tax benefits are reflected on a more likely than not basis. We evaluate uncertain tax positions based on ongoing facts and circumstances. Any change in judgment related to the expected resolution of uncertain tax positions is recognized in earnings in the period in which such change occurs. Interest and penalties, if any, related to unrecognized tax benefits are recorded as a component of income tax expense. Settlement of any particular position could require the use of cash. Favorable or unfavorable resolution for an amount less than or greater than the amount estimated by Barnwell will result in a decrease or increase to income tax expense in the period of resolution.

------

There were no changes in unrecognized tax benefits during the years ended September 30, 2025 or 2024.

Uncertain tax positions at September 30, 2025 are related to the potential assessment of penalties and interest for the failure to file a certain foreign information form with each of our U.S. federal income tax returns for fiscal years 2019, 2020 and 2021. The Company filed amended U.S. federal income tax returns which included the missing form and statement of reasonable cause for these years in September and October 2023 and requested abatement of any potential penalties and interest which could subsequently be assessed. The Company is awaiting a response from the IRS and the probability of success of the abatement request remains uncertain.

**11.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>SEGMENT AND GEOGRAPHIC INFORMATION</u>**

As disclosed in Note 3 "Discontinued Operations," on March 14, 2025, the Company completed the sale of Water Resources, which represented the Company's contract drilling segment. The financial results of the Company's contract drilling business has been presented as discontinued operations and therefore is excluded from segment reporting. Accordingly, Barnwell's continuing operations include the following two principal business segments:

*Oil and Natural Gas Segment* - Barnwell engages in oil and natural gas development, production, acquisitions and sales in Canada and in the U.S.

*Land Investment Segment* - Barnwell owns leasehold land interests in Hawaii.

The Company's Chief Operating Decision Maker is the Chief Executive Officer, who utilizes segment revenues and expenses and segment operating profit or loss to assess performance and allocate resources to each segment. General and administrative expenses are reviewed on a consolidated basis.

**14.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>FAIR VALUE MEASUREMENTS</u>**

*Fair Value of Financial Instruments*

The carrying values of cash and cash equivalents, accounts and other receivables, note receivable, accounts payable and accrued current liabilities approximate their fair values due to the short-term nature of the instruments.

*Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis*

The estimated fair values of oil and natural gas properties and the asset retirement obligation incurred in the drilling of oil and natural gas wells or assumed in the acquisitions of additional oil and natural gas working interests are based on an estimated discounted cash flow model and market assumptions. The assumptions used in the calculation of estimated discounted cash flows were primarily Level 3 assumptions; assumptions included future commodity prices, projections of estimated quantities of oil and natural gas reserves, expectations for timing and amount of future development, operating and asset retirement costs, projections of future rates of production, expected recovery rates and risk adjusted discount rates.

------

Barnwell estimates the fair value of asset retirement obligations based on the projected discounted future cash outflows required to settle abandonment and restoration liabilities. Such an estimate requires assumptions and judgments regarding the existence of liabilities, the amount and timing of cash outflows required to settle the liability, what constitutes adequate restoration, inflation factors, credit adjusted discount rates, and consideration of changes in legal, regulatory, environmental and political environments. Abandonment and restoration cost estimates are determined in conjunction with Barnwell's reserve engineers based on historical information regarding costs incurred to abandon and restore similar well sites, information regarding current market conditions and costs, and knowledge of subject well sites and properties. Asset retirement obligation fair value measurements in the current period were Level 3 fair value measurements. As further described in Note 8, the Company recognizes the fair value of a liability for an asset retirement obligation in the period in which it is incurred if a reasonable estimate of fair value can be made. Asset retirement obligations are not measured at fair value subsequent to initial recognition.

**15.&nbsp;&nbsp;&nbsp;&nbsp;<u>DEBT</u>**

*Insurance Premium Financing* 

In March 2025, the Company entered into a short-term financing agreement with a third-party to finance the Company's directors and officers insurance premium in the amount of $183,000, with a term of 11 months and an annual interest rate of 9.4%. The Company had made a down payment of $15,000 and was required to make monthly principal and interest payments of $16,000 over the term of the agreement, which was set to mature in February 2026. The insurance premium financing was repaid in full in September 2025.

**16.&nbsp;&nbsp;&nbsp;&nbsp;<u>LEASES</u>**

The Company's right-of-use ("ROU") assets and lease liabilities at September 30, 2025, primarily relate to non-cancelable operating leases for our Hawaii corporate and Canadian office spaces and our leasehold land interest for Lot 4C held by Kaupulehu Developments. Management determines if a contract is or contains a lease at inception of the contract or modification of the contract. A contract is or contains a lease if the contract conveys the right to control the use of the asset for a period in exchange for consideration.

&nbsp;&nbsp;&nbsp;&nbsp;Operating lease ROU assets and liabilities are recognized based on the present value of future minimum lease payments over the expected lease term at commencement date. The Company's leases do not provide a readily determinable implicit rate; therefore, management uses the Company's incremental borrowing rate to discount lease payments based on information available at lease commencement. Our lease terms may include options to extend or terminate the lease when it is reasonably certain we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease terms. The Company has lease agreements with lease and non-lease components and the non-lease components are excluded in the calculation of the ROU asset and lease liability and expensed as incurred. None of the Company's lease agreements contain material residual value guarantees or material restrictions or covenants. A ROU asset and corresponding lease liability is not recorded for leases with an initial term of 12 months or less (short-term leases) as the Company recognizes lease expense for these leases as incurred over the lease term.

The lease payments for the Lot 4C leasehold land zoned conservation were subject to renegotiation as of January 1, 2006. Per the lease agreement, the lease payments will remain unchanged pending an appraisal, whereupon the lease rent could be adjusted to fair market value. Barnwell does not know the amount of the new lease payments which could be effective upon performance of the appraisal; they may remain unchanged or increase, and Barnwell currently expects the adjustment, if any, to not be material.

------

The future lease payment disclosures above assume the minimum lease payments for leasehold land in effect at December 31, 2005 remain unchanged through December 2025, the end of the lease term.

*Share-based Payment Arrangements*

*2018 Equity Incentive Plan*

The stockholder-approved 2018 Equity Incentive Plan is administered by the Compensation Committee of the Board of Directors and provides for the issuance of incentive stock options, nonstatutory stock options, stock options with stock appreciation rights, restricted stock, restricted stock units and performance units, qualified performance-based awards, and stock grants to employees, consultants and non-employee members of the Board of Directors. 1,600,000 shares of Barnwell common stock have been reserved for issuance and as of September 30, 2025, a total of 751,724 shares remain available for grant.

Barnwell currently has a policy of issuing new shares to satisfy share option exercises when the optionee requests shares.

In October 2025, the Board of Directors of the Company granted a total of 133,335 restricted stock units to the independent directors of the Board as partial payment of director fees for their service as members of the Board. The restricted stock units vest ratably over a three-year period, subject to the director's continued service through the applicable vesting date.

On October 27, 2025, Barnwell Industries, Inc. appointed Philip Patman, Jr. as the Company's Executive Vice President – Finance and in connection with Mr. Patman's appointment, the Company entered into an executive employment agreement with Mr. Patman, dated, and effective, as of October 27, 2025 (the "Employment Agreement"). Pursuant to the terms of the Employment Agreement, on October 27, 2025, Mr. Patman received the following awards which were issued pursuant to the Company's Amended and Restated 2018 Equity Incentive Plan, as amended from time to time: a stock award of 83,207 shares of the Company's common stock; a restricted stock unit award for 83,208 shares of the Company's common stock (the "Initial RSU Award"); and an incentive stock option to purchase 185,000 shares of the Company's common stock (the "Initial Stock Option" and, together with the Initial RSU Award, the "Initial Equity Awards"). Both Initial Equity Awards vest according to the following schedule: 34% of the total on October 27, 2026; 33% of the total on October 27, 2027; and 33% of the total on October 27, 2028. The Initial Stock Option has a term of ten years and an exercise price of $1.21 per share (the closing price of the Company's common stock on October 27, 2025).

As of December 8, 2025, 266,974 shares remain available for grant under the 2018 Equity Incentive Plan.

*Stock Options*

In February 2021, the Company's Board of Directors (the "Board") granted options to purchase 665,000 shares of common stock, 310,000 shares to independent directors and 355,000 shares to employees. 605,000 shares of the stock options granted have an exercise price equal to the closing market price of Barnwell's stock on the date of grant of $3.33, vest annually over three years, and expire in ten years from the date of grant. 60,000 shares of the stock options granted have an exercise price of $3.66 (110% of the closing market price on the date of grant for options granted to affiliates), vest annually over

------

three years, and expire in five years from the date of grant. Of the 665,000 shares of common stock granted, 150,000 vested stock options expired and 100,000 shares were forfeited, both of which were as a result of director departures since the date of grant.

The following assumptions were used in estimating the fair value for equity-classified stock options granted in the year ended September 30, 2021:

---

| | | |
|:---|:---|:---|
| | > 10% Owner-Employee | Others |
| Number of shares | 60000 | 605000 |
| Expected volatility | 127.4% | 105.8% |
| Expected dividends |  |  |
| Expected term (in years) | 3.5 | 6.0 |
| Risk-free interest rate | 0.19% | 0.82% |
| Expected forfeitures |  |  |
| Fair value per share | $2.51 | $2.70 |

---

The application of alternative assumptions could produce significantly different estimates of the fair value of share-based compensation, and consequently, the related costs reported in the "General and administrative" expenses in the Consolidated Statements of Operations.

The following table summarizes Barnwell's equity-classified stock options activity from October 1, 2024 through September 30, 2025:

---

| | | | | |
|:---|:---|:---|:---|:---|
| Options | Shares | Weighted-<br>Average<br>Exercise Price | Weighted-<br>Average<br>Remaining<br>Contractual Term | Aggregate<br>Intrinsic Value |
| Outstanding at October 1, 2024 | 465000 | $3.37 |  |  |
| Granted |  |  |  |  |
| Exercised |  |  |  |  |
| Expired/Forfeited | (50000) | 3.33 |  |  |
| Outstanding at September 30, 2025 | 415000 | $3.38 | 4.6 | $— |
| Exercisable at September 30, 2025 | 415000 | $3.38 | 4.6 | $— |

Compensation cost for stock option awards is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period. During the years ended September 30, 2025 and 2024, the Company recognized share-based compensation expense related to stock options of nil and $50,000, respectively. There was no impact on income taxes for the years ended September 30, 2025 and 2024 due to a full valuation allowance on the related deferred tax asset. There is no remaining unrecognized compensation cost related to stock options as of September 30, 2025.

*Restricted Stock Units*

On November 2, 2023, the Board granted a total of 76,336 restricted stock units to the independent directors of the Board as partial payment of director fees for their service as members of the Board. The restricted stock units vest ratably over a three-year period, subject to the director's continued service through the applicable vesting dates; provided that, any unvested restricted stock would vest upon a director's death, disability, a change in control of the Company resulting in the director not continuing as a

------

director or the director not being renominated for election even though he was willing to stand for re-election.

On May 16, 2024, the Board granted 60,000 restricted stock units to the Company's President and Chief Executive Officer. The restricted stock units vest ratably over a three-year period, subject to the employee's continued service through the applicable vesting dates.

On October 24, 2024, the Board granted a total of 105,820 restricted stock units to the independent directors of the Board as partial payment of director fees for their service as members of the Board.

There was no impact on income taxes for the years ended September 30, 2025 and 2024 due to a net operating loss and net operating loss carryforwards with a full valuation allowance in the relevant taxing jurisdiction. As of September 30, 2025, the total remaining unrecognized compensation cost related to nonvested restricted stock units was $151,000, which is expected to be recognized over the weighted-average remaining requisite service period of 1.5 years.

*Common Stock Issued for Services*

On September 29, 2025, the Board approved and ratified a common stock grant to directors Kenneth Grossman and Joshua Horowitz for their services on behalf of the Company and the Board pertaining to the various legal actions between Ned L. Sherwood and certain of his affiliates and the Company and the 2025 shareholder proxy contest.

------

*Limited-Duration Shareholder Rights Plan*

On January 26, 2025, the Board adopted a shareholder rights plan and declared a dividend of one right (a "Right") in respect of each of the Company's issued and outstanding shares of common stock, par value $0.50 per share ("Common Stock"). The dividend was payable to the shareholders of record at the close of business on February 7, 2025. Each Right initially entitled the registered holder, subject to the terms of the Rights Agreement (as defined below), to purchase from the Company one share of Common Stock, at a price equal to $9.00, subject to certain adjustments (as adjusted from time to time, the "Exercise Price"). The terms of the Rights are set forth in the Rights Agreement, dated as of January 26, 2025 (as it may be amended from time to time, the "Rights Agreement"), by and between the Company and Broadridge Corporate Issuer Solutions, LLC, as rights agent (or any successor rights agent, the "Rights Agent").

In general terms, the Rights Agreement imposes significant dilution upon any person or group (other than the Company or certain related persons) that is or becomes the beneficial owner of 20% (the "Triggering Percentage") or more of the Company's outstanding Common Stock without the prior approval of the Board. A person or group that becomes the beneficial owner of the Triggering Percentage or more is called an "Acquiring Person." Any Rights held by an Acquiring Person will be null and void and may not be exercised. Shareholders that beneficially own the Triggering Percentage or more of the Company's outstanding Common Stock on the date the plan is adopted, are not considered Acquiring Persons; however, such Shareholders generally may not acquire, or obtain the right to acquire, beneficial ownership of 0.25% or more additional shares of the Company's outstanding Common Stock. The term "beneficial ownership" is defined in the Rights Agreement and includes, among other things, certain securities that may be exercised or converted into shares of Common Stock and certain derivative arrangements.

The Rights will expire prior to the earliest of (i) the close of business on January 26, 2026 (subject to the shareholders of the Company approving an extension of the Rights Agreement through a date on or prior to January 26, 2028); (ii) the time at which the Rights are redeemed pursuant to the Rights Agreement; (iii) the time at which the Rights are exchanged pursuant to the Rights Agreement; and (iv) upon the occurrence of certain transactions.

This description of the Rights Agreement herein does not purport to be complete and is qualified in its entirety by reference to Exhibit 4.1 to the Company's Current Report on Form 8-K, filed with the Securities and Exchange Commission on January 27, 2025.

*Incentive compensation plan*

Barnwell established incentive compensation plans to compensate the four oil and natural gas segment Canadian executive officers. The value of the plans are directly related to our oil and natural gas segment's free cash flows from Canadian properties and the divestiture of Canadian oil and natural gas assets. As of September 30, 2025, Barnwell has accrued approximately $118,000 in bonus compensation under these plans and the amount is reported in "Accrued compensation" on the Consolidated Balance Sheet.

------

*Environmental Matters*

Because of the inherent uncertainties associated with environmental assessment and remediation activities, future expenses to remediate sites identified in the future, if any, could be incurred. Barnwell's management is not currently aware of any significant environmental contingent liabilities requiring disclosure or accrual.

*Legal and Regulatory Matters*

Barnwell is routinely involved in disputes with third parties that occasionally require litigation. In addition, Barnwell is required to maintain compliance with all current governmental controls and regulations in the ordinary course of business. Barnwell's management is not aware of any claims or litigation involving Barnwell that are likely to have a material adverse effect on its results of operations, financial position or liquidity, other than the shareholder contest actions discussed elsewhere in this filing.

*Other Matters*

Barnwell is obligated to pay Nearco Enterprises Ltd. 10.4%, net of non-controlling interests' share, of Kaupulehu Developments' gross receipts from real estate transactions. This fee represents compensation for promotion and marketing of Kaupulehu Developments' property and were determined based on the estimated fair value of such services. These fees are included in general and administrative expenses.

Barnwell is obligated to pay its external real estate legal counsel's estate 1.2%, net of non-controlling interests' share, of all Increment II payments received by Kaupulehu Developments for services provided by its external real estate legal counsel in the negotiation and closing of the Increment II transaction. These fees are included in general and administrative expenses.

Kaupulehu Developments is also obligated to pay an amount equal to 0.72% and 0.20% of the cumulative net profits of KD II to KD Development and a pool of various individuals, respectively, all of whom are partners of KKM and are unrelated to Barnwell, in compensation for the agreement of these parties to admit the new development partner for Increment II. Such compensation will be reflected as the obligation becomes probable and the amount of the obligation can be reasonably estimated.

Additionally, the purchaser has the right to extend the closing by up to two years by making a $70,000 payment in each of the next two years, with those payments applied against the $2,000,000 purchase price. The closing of this transaction is entirely dependent on the purchaser and therefore may not happen.

**22.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>SUMMARY OF SELECTED QUARTERLY FINANCIAL DATA (UNAUDITED)</u>**

Disclosure is not required as Barnwell qualifies as a smaller reporting company.

**23.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>SUPPLEMENTARY OIL AND NATURAL GAS INFORMATION (UNAUDITED)</u>**

The following tables summarize information relative to Barnwell's oil and natural gas operations, which are conducted in Canada and was, until August 8, 2025, conducted in the U.S. states of Oklahoma and Texas (see Note 7). Proved reserves are the estimated quantities of oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved producing oil and natural gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. The estimated net interests in total proved and proved producing reserves are based upon subjective engineering judgments and may be affected by the limitations inherent in such estimations. The process of estimating reserves is subject to continual revision as additional information becomes available as a result of drilling, testing, reservoir studies and production history. There can be no assurance that such estimates will not be materially revised in subsequent periods.

*(A)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Oil and Natural Gas Reserves*

The following tables summarizes changes in the estimates of Barnwell's net interests in total proved reserves of oil and natural gas liquids and natural gas, which are now all located in Canada. All of the information regarding reserves in this Form 10-K is derived from the report of our independent petroleum reserve engineers, InSite, and is included as an Exhibit to this Form 10-K. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established proved producing oil and natural gas properties. Accordingly, these estimates are expected to change as future information becomes available.

Proved oil and natural gas reserves are the estimated quantities of oil and natural gas that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under economic and operating conditions (i.e., prices and costs) existing at the time the estimate is made.

*(E)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Standardized Measure, Including Year-to-Year Changes Therein, of Estimated Discounted Future Net Cash Flows*

The following tables utilize reserve and production data estimated by independent petroleum reserve engineers. The information may be useful for certain comparison purposes but should not be solely relied upon in evaluating Barnwell or its performance. Moreover, the projections should not be construed as realistic estimates of future cash flows, nor should the standardized measure be viewed as representing current value.

The estimated future cash flows at September 30, 2025 and 2024 were based on average sales prices in effect on the first day of the month for the preceding twelve month period in accordance with SEC Release No. 33-8995. The future production and development costs represent the estimated future expenditures that we will incur to develop and produce the proved reserves, assuming continuation of existing economic conditions. The future income tax expenses were computed by applying statutory income tax rates in existence at September 30, 2025 and 2024 to the future pre-tax net cash flows relating to proved reserves, net of the tax basis of the properties involved.

Material revisions to reserve estimates may occur in the future, development and production of the oil and natural gas reserves may not occur in the periods assumed and actual prices realized and actual costs incurred are expected to vary significantly from those used. Management does not rely upon this information in making investment and operating decisions; rather, those decisions are based upon a wide range of factors, including estimates of probable reserves as well as proved reserves and price and cost assumptions different than those reflected herein.

Barnwell has included all abandonment, decommissioning and reclamation costs and inactive well costs in accordance with best practice recommendations into the Company's reserve reports.

**ITEM 9A.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CONTROLS AND PROCEDURES**

**Disclosure Controls and Procedures**

We have established disclosure controls and procedures to ensure that material information relating to Barnwell, including its consolidated subsidiaries, is made known to the officers who certify Barnwell's financial reports and to other members of executive management and the Board of Directors.

As of September 30, 2025, an evaluation was carried out by Barnwell's Chief Executive Officer and Chief Financial Officer of the effectiveness of Barnwell's disclosure controls and procedures. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that Barnwell's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act")) were effective as of September 30, 2025 to ensure that information required to be disclosed by Barnwell in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Exchange Act and the rules thereunder.

**Management's Annual Report on Internal Control Over Financial Reporting**

Barnwell's management is responsible for establishing and maintaining adequate internal control over financial reporting for Barnwell, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Under the supervision and with the participation of Barnwell's management, including our Chief Executive Officer and Chief Financial Officer, Barnwell conducted an evaluation of the effectiveness of its internal control over financial reporting using criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in the report entitled *Internal Control — Integrated Framework (2013)* (the "COSO Framework"). Based on this evaluation under the COSO Framework, management concluded that its internal control over financial reporting was effective as of September 30, 2025.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Pursuant to Item 308(b) of Regulation S-K, management's report is not subject to attestation by our independent registered public accounting firm because the Company is neither an "accelerated filer" nor a "large accelerated filer" as those terms are defined by the SEC.

**Changes in Internal Control Over Financial Reporting**

There was no change in Barnwell's internal control over financial reporting during the quarter ended September 30, 2025 that materially affected, or is reasonably likely to materially affect, Barnwell's internal control over financial reporting.

------

**ITEM 9B.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; OTHER INFORMATION**

During the three months ended September 30, 2025, no director or officer of the Company adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408 of Regulation S-K.

The Company maintains a defined benefit pension plan ("Pension Plan") for its eligible U.S.-based employees to provide annual benefits payable on retirement. Eligibility is based upon attainment of age 21 and completion of one year of service. Benefits are calculated under a formula based upon years of service and the participant's highest average annual compensation over 60 consecutive months of service.

## Exhibit 4.2

Exhibit No. 4.2

**DESCRIPTION OF SECURITIES**

**REGISTERED PURSUANT TO SECTION 12 OF THE**

**SECURITIES EXCHANGE ACT OF 1934**

The following summary of Barnwell Industries, Inc.'s common stock is based on and qualified by our certificate of incorporation and amended and restated bylaws. For a complete description of the terms and provisions of our equity securities, including our common stock, refer to our certificate of incorporation and amended and restated bylaws, both of which are incorporated by reference as exhibits to this Annual Report on Form 10-K.

Our authorized capital stock consists of 40,000,000 shares of common stock, par value $0.50 per share.

**Common Stock**

Holders of shares of our common stock are entitled to one vote for each share on all matters voted upon by our stockholders, including the election of directors, and do not have cumulative voting rights. Unless otherwise required by law, our certificate of incorporation or amended and restated bylaws, any matter brought before any meeting of stockholders, other than the election of directors, is decided by the affirmative vote of a majority of the total voting power of common stock present in person or represented by proxy and entitled to vote thereon, a quorum being present. Each of our directors is elected by elected by the vote of a plurality of the votes cast at any meeting of stockholders held for the election of directors at which a quorum is present. Holders of shares of our common stock are entitled to participate equally and ratably in (i) any dividends that may be declared by our board of directors and (ii) our net assets upon our dissolution or liquidation. Holders of shares of our common stock do not have preemptive rights to purchase shares of our common stock. The shares of our common stock are not subject to any redemption provisions and are not convertible into any other shares of our capital stock.

**Provisions of Our Certificate of Incorporation, Bylaws and Delaware Law**

Under the Delaware General Corporation Law, or DGCL, the power to adopt, amend or repeal any provision of our bylaws is conferred upon the stockholders. A corporation may, however, in its certificate of incorporation also confer upon the board of directors the power to adopt, amend or repeal its bylaws. Our certificate of incorporation grants our board the power to adopt, amend and repeal our bylaws. Our stockholders may adopt, amend or repeal our bylaws, with the affirmative vote of a majority of total voting power of common stock present in person or represented by proxy and entitled to vote thereon.

Our certificate of incorporation and amended and restated bylaws provide that special meetings of our stockholders may be called by or at the direction a majority of the members of the board of directors, the Chairman of the board of directors, the Chief Executive Officer or the President of Barnwell and shall be called by the Secretary at the request in writing of stockholders of record of at least twenty-five percent (25%) in amount of the entire capital stock of the corporation issued and outstanding and entitled to vote thereat.

Our certificate of incorporation and amended and restated bylaws provide that stockholders may take any action required by law or our by-laws to be taken at any annual or special meeting of stockholders of Barnwell may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to Barnwell as required by law.

Our amended and restated bylaws provide advance notice procedures for stockholders seeking to bring business before the annual meeting of stockholders or to nominate candidates for election as directors at the annual meeting of stockholders. Our amended and restated bylaws also specify certain requirements regarding the form and content of a stockholder's notice. These provisions may preclude stockholders from bringing matters before the

------

annual meeting of stockholders or from making nominations for directors at the annual meeting of stockholders if the proper procedures are not followed.

We are subject to Section 203 of the DGCL, an anti-takeover law. In general, this section prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date such person became an interested stockholder, unless the business combination or the transaction in which such person became an interested stockholder is approved in a prescribed manner. Generally, a "business combination" includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an "interested stockholder" is a person that, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation's voting stock. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by our board, including discouraging attempts that might result in a premium over the market price for the shares of our common stock.

**Rights Agreement**

We are party to a Rights Agreement (the "Rights Agreement"), dated as of January 26, 2025, between Barnwell and Broadridge Corporate Issuer Solutions, LLC, as rights agent. Pursuant to the Rights Agreement, on January 26, 2025, our board of directors authorized and declared a dividend distribution of one right (each, a "Right") for each outstanding share of our common stock, which dividend was payable to holders of record as of the close of business on February 7, 2025 (the "Record Date").

Each Right entitles the registered holder thereof to purchase from Barnwell, when exercisable and subject to adjustment, one share of common stock, at a purchase price of $9.00 per share, subject to adjustment (the "Purchase Price").

The following is a summary of the material terms of the Rights Agreement and is qualified in its entirety by reference to the full text of the Rights Agreement, which is incorporated by reference as an exhibit to this Annual Report on Form 10-K.

*Rights Certificates; Exercise Period; Term*

Initially, the Rights attached to all certificates for shares of common stock then outstanding (or for book entry shares of common stock, the Rights are represented by notations in the respective book entry accounts), and no separate rights certificates ("Rights Certificates") will be distributed. Subject to certain exceptions specified in the Rights Agreement, the Rights will separate from the common stock and a distribution date for the Rights (the "Distribution Date") will occur upon the earlier of the (i) tenth (10<sup>th</sup>) business day following a public announcement that a person or group of affiliated or associated persons (such person or group being an "Acquiring Person"), other than certain exempt persons, has acquired beneficial ownership of twenty percent (20%) or more of the outstanding shares of common stock (including ownership of derivative securities which have an exercise or conversion privilege or a settlement payment or mechanism at a price related to the common stock or a value determined in whole or part with reference to, or derived in whole or in part from, the market price or value of the common stock), other than as a result of (a) pre-existing beneficial ownership in excess of the applicable threshold (in which case such person shall become an Acquiring Person if they become the beneficial owner of additional shares of common stock representing more than 0.25% of the outstanding shares of common stock, subject to certain exceptions), (b) repurchases of shares of common stock or securities convertible or exchangeable into shares of common stock by Barnwell, (c) certain inadvertent acquisitions or (d) certain other situations (as specified in the Rights Agreement) and (ii) tenth (10th) business day (or such later date as the board of directors may determine) following the commencement of a tender or exchange offer by any person that would result in a person or group becoming an Acquiring Person. For purposes of the Rights Agreement, beneficial ownership is defined to include derivative securities.

------

Until the Distribution Date, (i) the Rights will be evidenced by the certificates for shares of common stock (or, for book entry shares of common stock, by the notations in the respective book entry accounts) and will be transferred with, and only with, such common stock, (ii) new certificates for shares of common stock issued after the Record Date will contain a notation incorporating the Rights Agreement by reference (for book entry shares of common stock, this legend will be contained in the notations in book entry accounts) and (iii) the surrender for transfer of any outstanding shares of common stock will also constitute the transfer of the Rights associated with such common stock.

The Rights are not exercisable until the Distribution Date and, subject to the shareholders of Barnwell approving an extension of the Rights Agreement through a date on or prior to January 26, 2028, will expire at the close of business on January 26, 2026, unless the Rights are earlier redeemed, exchanged or terminated.

*Change of Exercise of Rights Following Certain Events*

The following described events are referred to as "Triggering Events."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Flip-In Event*. In the event that a person or group of affiliated or associated persons becomes an Acquiring Person, each holder of a Right will thereafter have the right to receive, upon exercise and payment of the Purchase Price, one share of common stock per Right. Notwithstanding any of the foregoing, following the occurrence of a person becoming an Acquiring Person, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person (or by certain related parties) will be null and void and any holder of such Rights (including any purported transferee or subsequent holder) will be unable to exercise or transfer any such Rights. However, Rights are not exercisable following the occurrence of a person becoming an Acquiring Person until the Distribution Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Flip-Over Events*. In the event that, at any time after a person has become an Acquiring Person, (i) Barnwell engages in a merger or other business combination transaction in which Barnwell is not the continuing or surviving corporation, (ii) Barnwell engages in a merger or other business combination transaction in which Barnwell is the continuing or surviving corporation and the shares of common stock of Barnwell are changed or exchanged, or (iii) fifty percent (50%) or more of Barnwell's assets, cash flow, or earning power is sold or transferred, each holder of a Right (except Rights that have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise and payment of the Purchase Price, one share of the common stock (or substantially equivalent voting equity securities) of the acquiring company per Right.

*Redemption*

At any time until the earlier of (i) ten (10) business days following public announcement that an Acquiring Person has become such (the "Stock Acquisition Date") or (ii) the expiration of the Rights Agreement, the board of directors may direct Barnwell to redeem all but not less than all of the then outstanding Rights, at a price of $0.001 per Right (payable in cash or other consideration deemed appropriate by the board of directors), subject to adjustment as provided in the Rights Agreement (the "Redemption Price"). Immediately upon the action of the board of directors directing Barnwell to redeem the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. The Rights may only be exercised once the company's right to redeem the Rights has expired.

*Exchange of Rights*

At any time after a person or group of affiliated or associated persons becomes an Acquiring Person but before any person acquires beneficial ownership of fifty percent (50%) or more of the outstanding shares of common stock, the board of directors may direct Barnwell to exchange the Rights (other than Rights owned by such person or certain related parties, which will have become null and void and non-transferable as described above), in whole or in part, at an exchange ratio of one share of common stock per Right (subject to adjustment). If there are insufficient authorized shares of common stock to effect an exchange of the Rights, Barnwell may substitute cash, other securities having equivalent rights, preferences, and privileges to the shares of common stock, debt securities, other

------

assets or any combination of the foregoing having a value equal to one share of common stock in lieu of shares of common stock. Immediately upon the action of the board of directors directing Barnwell to exchange the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the number of shares of common stock (or cash, other equivalent securities, debt securities or other assets) equal to the number of Rights held by such holder multiplied by the exchange ratio.

*Certain Adjustments*

In order to preserve the actual or potential economic value of the Rights, the number of shares of common stock or other securities issuable upon exercise of the Rights and the number of Rights associated with each outstanding share of common stock are all subject to adjustment by the board of directors pursuant to certain customary anti-dilution provisions.

*No Shareholder Rights Prior to Exercise*

Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of Barnwell, including, without limitation, the right to vote or to receive dividends.

*Amendment of Rights Agreement*

Subject to certain exceptions specified in the Rights Agreement, for so long as the Rights are then redeemable, the terms of the Rights and the Rights Agreement may be amended without the approval of any holders of Rights. Subject to certain exceptions specified in the Rights Agreement, after the Rights are no longer redeemable, the provisions of the Rights Agreement may be amended by Barnwell, without the approval of any holder of Rights, including to shorten or lengthen any time period under the Rights Agreement, so long as no such amendment (a) adversely affects the interests of the holders of the Rights as such, (b) causes the Rights Agreement to become amendable other than as already provided in the Rights Agreement or (c) causes the Rights to again become redeemable.

*Certain Anti-Takeover Effects; Miscellaneous*

The Rights are not intended to prevent a takeover of Barnwell and should not interfere with any merger or other business combination approved by the board of directors. However, the Rights may cause substantial dilution to a person or group of affiliated or associated persons that acquires beneficial ownership of twenty percent (20%) or more of the outstanding shares of Common Stock (existing holders owning twenty percent (20%) or more of the outstanding shares of common stock will only trigger the rights plan if they become the beneficial owner of additional shares of common stock following the date of adoption that represent more than 0.25% of the outstanding shares of common stock, subject to certain exceptions). As a result, the overall effect of the Rights may be to render more difficult or discourage a change of Barnwell's investment advisor or a merger, tender offer, or other business combination involving Barnwell that is not supported by the board of directors.

**Transfer Agent and Registrar**

The transfer agent and registrar for our common stock is Broadridge Corporate Issuer Solutions, Inc., 51 Mercedes Way, Edgewood, NY 11717.

Our common stock is listed on the NYSE American under the symbol "BRN".

Exhibit No. 19.1

BARNWELL INDUSTRIES, INC.

STATEMENT OF COMPANY POLICY

ON INSIDER TRADING

<u>The Need for a Policy Statement</u>

The purchase or sale of securities of Barnwell Industries, Inc. while possessing material nonpublic ("insider") information relating to Barnwell or any of its subsidiaries (together, the "Company") or the selective disclosure of such information to others who may trade in the securities of the Company is prohibited by federal and state securities laws. As part of your employment, many of you have access to material nonpublic information about the Company or about the Company's business (including information about other companies with which the Company does or may do business).

Barnwell has adopted this Policy Statement to avoid even the appearance of improper conduct on the part of the Company employee (not just so-called insiders). Since its beginning Barnwell has worked hard to establish a reputation for integrity, ethical conduct and good corporate citizenship. Barnwell expects all Company employees to adhere to this Policy Statement and thereby help us preserve and further this reputation.

<u>Policy</u>

No Company director, officer or employee who has material nonpublic information relating to the Company may directly or indirectly buy or sell securities of Barnwell or engage in any other action to take personal advantage of such information, or pass it on to others. The insider trading policy also applies to your family members who reside with you, anyone else who lives in your household, and any family members who do not live in your household but whose transactions in Company securities are directed by you or are subject to your influence or control (such as parents or children who consult with you before they trade in Company securities). You are responsible for the transactions of these other persons and therefore should make them aware of the need to confer with you before they trade in the Company's securities. This policy also applies to information relating to any other company, including customers or suppliers of the Company, obtained in the course of employment. Transactions that may be necessary or justifiable for independent reasons (such as the need to raise money for an emergency expenditure) are no exception. Even the appearance of an improper transaction must be avoided.

<u>Liability of Supervisory Persons</u>

Barnwell, as well as any Company director, officer or employee, may be subject to liability under applicable securities laws if Barnwell or such person knew or recklessly

------

disregarded the fact that a person directly or indirectly under Barnwell's or such person's control was likely to engage in insider trading and failed to take appropriate steps to prevent such an act before it occurred. The penalties for such inaction can be significant.

If material nonpublic information is inadvertently disclosed, no matter what the circumstances, by any Company director, officer or employee, the person making or discovering such disclosure should immediately report it to Barnwell's general counsel.

<u>Definition of Material Nonpublic Information</u>

"Material" information is any information that a reasonable investor would likely consider important in a decision to buy, hold or sell securities – in short, any information which could reasonably affect the price of the securities of Barnwell, whether positive or negative.

"Nonpublic" information is any information which has not been disclosed generally to the marketplace. Information about the Company that has not yet been contained in a filing made by Barnwell with the Securities and Exchange Commission or otherwise been made generally available through press release or other general form of public disclosure by Barnwell should be considered nonpublic. All information that you learn about the Company or its business plans in connection with your employment is potentially "insider" information until publicly disclosed or made available by Barnwell. You should treat all such information as confidential and proprietary to Barnwell. Similarly, information received about another company in circumstances indicating that it is not yet in general circulation should be considered nonpublic. Nonpublic information may not be disclosed to others, including family members, relatives, friends and social acquaintances or business associates, who do not need to know it for legitimate business reasons. If nonpublic information is also "material" you are required by law and this Policy Statement to refrain from trading in the securities of Barnwell and from passing the information on to others who may trade in the securities of Barnwell.

Common examples of information that will frequently be regarded as material, assuming it has not been publicly disclosed by Barnwell, are financial results, including earnings or losses; projections of future earnings or losses; major marketing changes; news of a pending or proposed joint venture, merger, acquisition, tender offer or securities offering; news of a significant sale of assets or the disposition of a subsidiary; changes in dividend policies or the declaration of a stock split or the offering of additional securities; changes in management; major personnel changes; significant litigation or government investigations; or the gain or loss of a substantial customer or supplier.

Remember, if your securities transactions become the subject of scrutiny, they will be viewed after-the-fact with the benefit of hindsight. As a result, before engaging in any securities transaction you should carefully consider how regulators and others might view such transaction in the future.

------

<u>Tipping Information to Others</u>

Whether the information is proprietary information about the Company or information that could have an impact on the price of Barnwell's securities, you must not pass the information on to others, including family members, relatives and others living in your home, friends and social acquaintances or business associates. Employees are expected to be responsible for the compliance with this Policy Statement by their family members and others living in their home. The above restrictions and penalties apply whether or not you derive any benefit from another's actions.

<u>Timing</u>

It would be improper for a Company employee to trade securities of Barnwell immediately after Barnwell has made a public announcement of material information, including releases of financial results. Because Barnwell's shareholders and the investing public should be afforded the time to receive the information and act upon it, as a general rule you should not engage in any transactions until at least three full business days after material information has been released publicly, if such release has been made in a national medium, or five full business days after material information has been released publicly, where the release is not so widespread.

<u>Blackout Periods and Trading During Window Periods</u>

Investment by Company employees in Barnwell securities is encouraged. The most appropriate periods to buy or sell securities of Barnwell are the period beginning on the third business day and ending on the fifteenth business day following the release of quarterly or annual financial results (so-called "window periods"). If you participate in the preparation of the Company's financial statements or otherwise learn of the Company's financial performance by virtue of nonpublic information, you should refrain from trading in securities of Barnwell for the one-month "blackout" period immediately preceding the preliminary announcement of Barnwell's quarterly or annual financial results. If you are ever uncertain when the blackout periods occur, please ask for clarification from Barnwell's general counsel.

From time to time, an event may occur, or be about to occur, that is material to the Company and is known by only a few directors or executive officers. Upon the occurrence, or pending occurrence, of such an event, the general counsel may notify the directors and such other executive officers or other persons as he or she may designate that an event-specific blackout period is in effect. For so long as the event remains material and nonpublic, the persons who are aware of the event, as well as other persons covered by the quarterly earnings blackout procedures, may not trade in the Company's securities. The existence of an event-specific blackout will not be announced, other than to those who are aware of the event giving rise to the blackout. If, however, a person whose trades are subject to pre-clearance requests permission to trade in the Company's securities during an event-specific blackout, the general counsel will inform the requesting person of the existence of a blackout period, without disclosing the reason for the blackout. Any person

------

made aware of the existence of an event-specific blackout should not disclose the existence of the blackout to any other person. The failure of any person to be designated as being subject to an event-specific blackout will not relieve that person of the obligation not to trade while aware of material nonpublic information.

It is permissible to trade at other times, provided that prior to trading you contact Barnwell's general counsel if required below. This pre-clearance procedure will help in monitoring compliance with this Policy Statement and securities laws that may be applicable to your proposed transaction. Remember, however, you may not buy or sell Barnwell securities even during window periods if you are in possession of material nonpublic information. These rules apply to gifts, pledges of stock and hedges.

<u>Company Assistance</u>

Any person who has a question about a specific transaction may obtain additional guidance from Barnwell's general counsel. Remember, however, the ultimate responsibility for adhering to this Policy Statement and avoiding improper transactions rests with you. It is imperative that you use your best judgment.

<u>Pre-Clearance of Trades by Directors, Officers and Certain Other Personnel</u>

To provide assistance in preventing inadvertent violations and avoiding even the appearance of an improper transaction (which could result, for example, where an officer or other managerial employee of the Company trades in securities of Barnwell while unaware of a pending major development), the procedure set forth below must be followed by the directors, officers and other managerial personnel of the Company, all individuals reporting directly to such persons and by other Company employees who are likely to have access to material nonpublic information. If you are uncertain whether you fall into the category of people to whom the pre-clearance requirement applies, please ask Barnwell's general counsel. Any request for pre-clearance must be received by the general counsel at least two business days in advance of the proposed transaction.

All transactions in securities of Barnwell (acquisitions, dispositions, transfers, puts, calls, options, etc.) by any person in one of the above-mentioned categories must be pre-cleared by Barnwell's general counsel. If you are a member of one of these designated groups and are contemplating a transaction, you should contact Barnwell's general counsel in advance. This requirement does not apply to stock option exercises or purchases under Barnwell's stock purchase plan, but would cover market sales of Barnwell securities obtained pursuant to stock option plans.

<u>Public Disclosure of Insider Information</u>

If you believe you may be in possession of material nonpublic information, do not disclose that information to anyone outside the Company or to anyone within the Company who does not have a need to know such information without first discussing it with Barnwell's general counsel.

------

<u>Additional Prohibited Transactions</u>

**The Company considers it improper and inappropriate for any director, officer or other employee of the Company to engage in short-term or speculative transactions in the Company's securities. It therefore is the Company's policy that directors, officers and other employees may not engage in any of the following transactions:**

<u>Short Sales</u>*.* Short sales of the Company's securities evidence an expectation on the part of the seller that the securities will decline in value, and therefore signal to the market that the seller has no confidence in the Company or its short-term prospects. In addition, short sales may reduce the seller's incentive to improve the Company's performance. For these reasons, short sales of the Company's securities are prohibited by this Policy Statement. In addition, Section 16(c) of the Securities Exchange Act of 1934 prohibits officers and directors from engaging in short sales.

<u>Publicly Traded Options</u>*.* A transaction in options is, in effect, a bet on the short-term movement of the Company's stock and therefore creates the appearance that the director or employee is trading based on inside information. Transactions in options also may focus the director's or employee's attention on short-term performance at the expense of the Company's long-term objectives. Accordingly, transactions in puts, calls or other derivative securities, on an exchange or in any other organized market, are prohibited by this Policy Statement. (Option positions arising from certain types of hedging transactions are governed by the section below captioned "Hedging Transactions.")

<u>Hedging Transactions</u>*.* Certain forms of hedging or monetization transactions, such as zero-cost collars and forward sale contracts, allow an employee to lock in much of the value of his stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock. These transactions allow the director or employee to continue to own the covered securities, but without the full risks and rewards of ownership. When that occurs, the director or employee may no longer have the same objectives as the Company's other shareholders. Therefore, directors and employees are prohibited from engaging in any such transactions.

<u>Exception for Approved 10b5-1 Plans</u>

Trades by covered persons in the Company's securities that are executed pursuant to an approved 10b5-1 plan are not subject to the prohibition on trading on the basis of material nonpublic information contained in this Policy Statement or to the restrictions set forth above relating to pre-clearance procedures and blackout periods.

Rule 10b5-1 provides an affirmative defense from insider trading liability under the federal securities laws for trading plans that meet certain requirements. In general, a 10b5-1 plan must be entered into before you are aware of material nonpublic information. Once the plan is adopted, you must not exercise any influence over the amount of securities to be traded, the price at which they are to be traded or the date of the trade. The

------

plan must either specify (including by formula) the amount, pricing and timing of transactions in advance or delegate discretion on those matters to an independent third party.

The Company requires that all 10b5-1 plans be approved in writing in advance by the general counsel. 10b5-1 plans generally may not be adopted during a blackout period and may only be adopted before the person adopting the plan is aware of material nonpublic information.

<u>Post-Termination Transactions</u>

The Policy Statement continues to apply to your transactions in Company securities even after your employment or other service relationship terminates. If you are aware of material nonpublic information when your employment or other service relationship terminates, you may not trade in Company securities until that information has become public or is no longer material.

**Re:&nbsp;&nbsp;&nbsp;&nbsp;Evaluation of the Oil and Gas Properties of**

**&nbsp;&nbsp;&nbsp;&nbsp;Barnwell of Canada, Limited and Octavian Oil Ltd.**

Dear Sirs:

As requested, an evaluation has been made of all of the crude oil and natural gas assets of Barnwell of Canada, Limited and Octavian Oil Ltd., hereinafter referred to as the "Company." The properties evaluated are located in the Canadian provinces of Alberta and British Columbia. The effective date of the reserve estimates presented in this report is September 30, 2025. The purpose of this evaluation and report is to fulfill Securities and Exchange Commission (SEC) reporting requirements.

All Company assets were evaluated in full detail. Individual property evaluations were prepared in the context of belonging to a larger portfolio of properties. Due to the principal of aggregation of reserves, the total portfolio reserves estimate carries a higher degree of confidence than the estimates for the individual properties.

This evaluation is based in part on prices, currency exchange rates and estimates which, in future, may differ materially from the forecasts utilized herein. In addition, changes in government policy and regulation may result in higher (or lower) royalties and taxes and the change may be material; therefore, the present values of revenues documented in this report do not necessarily represent the fair market value of the reserves evaluated. The reserve estimates presented in this report are considered reasonable as of the effective date of the report given the quality and quantity of data available; however, they should be accepted with the understanding that reservoir performance subsequent to the date of these estimates may necessitate revision, which may be material.

| &nbsp;&nbsp;&nbsp;&nbsp; Total Proved | <u>642900</u> | <u>165300</u> | <u>3428700</u> |

Constant prices were prepared based on posted prices of crude oil and natural gas, and natural gas liquids using a 12 month unweighted arithmetic average closing price of each commodity on the 1<sup>st</sup> day of each month from October 1, 2024 through September 1, 2025 during the fiscal year. This report has been prepared using constant prices and costs and conforms to our understanding of the SEC's guidelines and applicable financial accounting rules.

All prices used in the evaluation have been adjusted from posted prices for applicable quality, heating value and transportation considerations. The weighted average prices, after applicable adjustments, over the life of the properties used in the evaluation were US$60.92 barrel of oil, US$1.09 per Mcf of gas, US$35.51 per barrel of condensate and natural gas liquids.

During the course of the evaluation, the Company provided InSite Petroleum Consultants Ltd. ("InSite") personnel with basic information including land data, well information, geological information, reservoir studies, estimates of on-stream dates, contract details, operating cost data, capital budget forecasts, operating statements and other financial data and future operating plans. Additional engineering, geological or economic data used in the preparation of this report were obtained from public records, other operators and from InSite non-confidential files. InSite encountered no indications that the data was incomplete or inaccurate. Should evidence become available in the future suggesting that the data was incomplete or inaccurate, InSite reserves the right to revise the estimates based on new data. Similarly, the performance of the producing entities subsequent to the effective date of this report may necessitate upward or downward revisions to the reserve and production estimates.

In conducting our reserve analysis, proved reserve volumes were determined by volumetric, material balance, and production decline curve methods. The volumetric reserves were determined by reviewing all well logs, core, and geological data. Recovery factors were assigned after analyzing the performance of similar wells in the area. Historical well production was reviewed to determine reserves calculated by production decline curve analysis where sufficient historical data was available. The order of preference in choosing the methodology to be used was firstly production decline curve analysis or material balance where sufficient data was available for such analysis with volumetric calculations used where there was a lack of historical data.

The production and revenue forecasts for each property and the corporate cash flow summaries have not been adjusted for risk. Well abandonment, decommissioning and site reclamation costs (ADR) were included in the economic runs for all wells with reserves assigned, as wells as the ADR costs for producing wells with no reserves assigned, suspended wells and existing facilities. The ADR costs and timing were adopted from the Company's internal Asset Retirement Obligation (ARO) estimates.

The oil and gas reserves calculations and income projections upon which this report is based, were determined in accordance with generally accepted evaluation practices. InSite used all assumptions, data, methods and procedures it considered appropriate, under the circumstances, to prepare this report.

The extent and character of ownership and all factual data supplied by the Company were accepted as presented. A field inspection was not considered necessary by InSite.

In this report, gross (or Company share) reserves are defined as the total remaining recoverable reserves owned by the Company before deduction of any royalties. Net reserves are defined as those accruing to the Company after all interests owned by others including Crown and Freehold royalties have been deducted. The reserve category definitions utilized in this report are in accordance with SEC standards and Regulation S-X.

Yours very truly,

**InSite Petroleum Consultants Ltd.**
