Barnwell Industries Inc: Form 10-K for the period ended Sep 30, 2025

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:

• 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 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.

8

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.

* 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.”

* Calculated on revenues net of pipeline charges before royalty expense divided by gross production.

** Calculated on revenues before royalty expense divided by gross production.

*** Calculated on production costs, excluding natural gas pipeline charges, divided by the combined total production of natural gas liquids, oil and natural gas.

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.

* “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.

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.”

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:

• fluctuations in commodity prices;
• variations in results of operations;
• announcements by us and our competitors;
• legislative or regulatory changes;
• general trends in the industry;
• general market conditions;
• litigation; and
• 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:

• oil and natural gas prices as prescribed by SEC regulations;
• historical production from our wells compared with production rates from similar producing wells in the area;
• future commodity prices, production and development costs, royalties and capital expenditures;
• initial production rates;
• production decline rates;
• ultimate recovery of reserves;
• success of future development activities;
• marketability of production;
• effects of government regulation; and
• 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.

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.

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:

• restrictions imposed by lenders;
• accounting delays;
• delays in the sale or delivery of products;
• delays in the connection of wells to a gathering system;
• blowouts or other accidents;
• adjustments for prior periods;
• recovery by the operator of expenses incurred in the operation of the properties; and
• 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:

• 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;
• potential for future additional capital contributions to fund operations and development activities;
• the adverse impact on overall profitability if the entities do not achieve the financial results projected;
• 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;
• 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
• 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.

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.

Oil and Natural Gas and Land Investment Properties

The location and character of Barnwell’s oil and natural gas properties and its land investment properties, are described above under Item 1, “Business.”

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

Policy Description

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.

Judgments and Assumptions

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

Policy Description

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.

Judgments and Assumptions

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:

• 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.
• 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.
• 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.

• 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:

• 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;
• 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;
• 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
• 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.

Oil and natural gas

Selected Operating Statistics

The following tables set forth Barnwell’s annual average prices per unit of production and annual net production volumes for fiscal 2025 as compared to fiscal 2024. Production amounts reported are net of royalties.

* Natural gas price per unit is net of pipeline charges.

The oil and natural gas segment generated a $588,000 operating profit in fiscal 2025 before general and administrative expenses, an increase in operating results of $873,000 as compared to a $285,000 operating loss in fiscal 2024.

The following table sets forth Barnwell’s oil and natural gas segment operating profit (loss) before general and administrative expenses by geographic location:

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

(2) 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.

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:

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:

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.

Contractual Obligations

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

Contingencies

For a detailed discussion of contingencies, see Note 18 in the “Notes to Consolidated Financial Statements” in Item 8 of this report.

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.
