KOLIBRI GLOBAL ENERGY INC. ANNOUNCES 2025 PROVED DEVELOPED RESERVE INCREASE OF 30% AND YEAREND EARNINGS CALL

Thousand Oaks CALIFORNIA, March 17, 2026 – Kolibri Global Energy Inc. (the “Company” or “KGEI”) (TSX: KEI, NASDAQ: KGEI) is providing the results of its December 31, 2025, independent reserves evaluation. All amounts are in US$ unless otherwise stated.

Wolf Regener, President and CEO, commented: “We are very pleased that our proved developed producing reserves increased by 30 percent due to our successful 2025 drilling program. Proved developed producing reserves valuation (NPV discounted at 10%) increased by 10% to $189 million, despite the much lower oil prices used in this reserve report. The 2026 oil price used in the reserve report is $58 a barrel which is 24% below the previous year’s report of $76 a barrel. This is in stark contrast to current oil prices, which are in excess of $90 per barrel.

“Total proved reserves increased 1% in 2025, even though we drilled almost all of our wells in Proved locations and produced approximately 1.5 million barrels of oil equivalent (BOE) of proved reserves. And, with our percentage of PDP versus Total Proved reserves at 29%, we still have a significant amount of proved undeveloped reserves to be able to convert into future production.

“Over the last three years, we have achieved a fantastic 35% compound annual production growth rate. We look forward to continuing our success with our drilling program this year, which we are planning to begin in June. We are preparing multiple pad locations to quickly give us the ability to increase our drilling activity if oil prices remain elevated through 2026.”

2025 Gross Reserves Summary

- an increase of 1% from the December 31, 2024, estimate

- an increase of 7% from the December 31, 2024, estimate

- an increase of 0.5% from the December 31, 2024, estimate - a decrease of 18% from the December 31, 2024 estimate

Net Present Value of Reserves discounted at 10%

- a decrease of 16% from the December 31, 2024 estimate

- a decrease of 20% from the December 31, 2024 estimate

The evaluation of the Company’s reserves in the Caney formation of the Tishomingo Field in the SCOOP area of Oklahoma was conducted by Netherland, Sewell & Associates, Inc. (“NSAI”) in accordance with National Instrument 51-101 – Standards of Disclosure for Oil and Gas Activities.

The above total Proved reserves are attributed to the 45 Caney wells, four Woodford wells (4.9% working interest for the Company) and one Sycamore well (0.7% working interest for the Company), and the drilling of 34.85 net additional wells over the next four years. The Probable reserves are attributed to the drilling of 10.92 net additional wells over the next five years. The wells in NSAI’s 2025 report are planned at 107 to 213 acre spacing (6 wells per section) on approximately 17,696 net acres.

Net Present Value of Future Net Revenue

As of December 31, 2025

Forecast Prices & Costs

Note: All dollar values are expressed in U.S. dollars and may not add due to rounding.

The Company’s reserves are derived from non-conventional oil and gas activities. The Company’s reserves are contained in a shale oil reservoir from which light/medium oil is produced and gas and natural gas liquids are produced as by-products. In previous statements, the light/medium oil was referred to as “tight oil”.

These after-income tax net present values reflect the tax burden on the Company’s Tishomingo Field interests on a standalone basis, do not consider the business-entity-level tax situation or tax planning, and do not provide an estimate of the value at the level of the business entity, which may be significantly different. The financial statements and the management’s discussion and analysis (MD&A) of the Company should be consulted for information at the level of the business entity.

Readers are referred to the Company’s Form 51-101F1 Statement of Reserves Data and Other Oil & Gas Information for the year ended December 31, 2025, which can be accessed electronically from the SEDAR+ website at www.sedarplus.ca, for additional information.

Year End Earnings Release and Earnings Call

The Company expects to release financial and operating results for 2025 before the market opens on March 19, 2026.

In connection with the earnings release, management will host a conference call for investors and analysts on March 19, 2026, at 9:00 a.m. Pacific time to discuss the Company’s results and to host a Q&A session. Interested parties are invited to participate by calling:

When calling, please request to be joined into the Kolibri Global Energy Inc. call.

“BOEs” refers to barrels of oil equivalent. BOEs/boes may be misleading, particularly if used in isolation. A boe conversion ratio of 6 Mcf:1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. There is a 10% probability that the quantities actually recovered will equal or exceed the sum of provided plus probable plus possible reserves. The present value of estimated future net revenues referred to herein does not represent fair market value and should not be construed as the current market value of estimated crude oil and natural gas reserves attributable to the Company’s properties. Readers should be aware that references to initial production rates and other short-term production rates are preliminary in nature and are not necessarily indicative of long-term performance or of ultimate recovery.

This news release includes references to sales volumes of “oil”, “natural gas”, and “barrels of oil equivalent” or “BOEs”. “Oil” refers to light crude oil and medium crude oil combined, and “natural gas” refers to shale gas, in each case as defined by NI 51-101. Production from our wells, primarily disclosed in this news release in BOEs, consists of mainly oil and associated wet gas. The wet gas is delivered via gathering system and then pipelines to processing plant where it is treated and sold as natural gas and NGLs.

Caution Regarding Forward-Looking Information

Certain statements contained in this news release constitute “forward-looking information” as such term is used in applicable Canadian securities laws, including statements regarding estimates of reserves and future net revenue and cash flow, expectations regarding additional reserves and statements regarding Caney wells development, including plans, anticipated results, and timing and the Company’s working interest, and expectations regarding the Company’s 2026 drilling program. Forward-looking information is subject to a variety of risks and uncertainties and other factors that could cause plans, estimates and actual results to vary materially from those projected in such forward-looking information. Estimated reserves and future net revenue have been independently evaluated by NSAI with an effective date of December 31, 2025. This evaluation is based on a limited number of wells with limited production history and includes a number of assumptions relating to factors such as availability of capital to fund required infrastructure, commodity prices, production performance of the wells drilled, successful drilling of infill wells, the assumed effects of regulation by government agencies and future capital and operating costs. All of these estimates will vary from actual results. Estimates of the recoverable oil and natural gas reserves attributable to any particular group of properties, classifications of such reserves based on risk of recovery and estimates of future net revenues expected therefrom, will vary. The Company’s actual production, revenues, taxes, development and operating expenditures with respect to its reserves will vary from such estimates, and such variances could be material. Estimates of after-tax net present value are dependent on a number of factors including utilization of tax-loss carry forwards. In addition to the foregoing, other significant factors or uncertainties that may affect either the Company’s reserves or the future net revenue associated with such reserves include material changes to existing taxation or royalty rates and/or regulations, and changes to environmental laws and regulations. Forward-looking information regarding Caney wells development and expectations regarding additional reserves are based on plans and estimates of management and interpretations of exploration information by the Company’s exploration team at the date the information is provided and is subject to several factors and assumptions of management, including that required regulatory approvals and capital will be available when required, that completion techniques require further optimization, that production rates do not match the Company’s assumptions, that very low or no production rates are achieved, that the demand for oil and gas will be sustained, that the price of oil will be sustained or increase, that no unforeseen delays, unexpected geological or other effects, equipment failures, permitting delays or labor or contract disputes or shortages are encountered, that the development plans of the Company and its co-venturers will not change, and is subject to a variety of risks and uncertainties and other factors that could cause plans, estimates and actual results to vary materially from those projected in such forward-looking information, including that anticipated results and estimated costs will not be consistent with managements’ expectations, the risk of commodity price and foreign exchange rate fluctuations, the Company or its subsidiaries not being able for any reason to obtain and provide the information necessary to secure required approvals or that required regulatory approvals are otherwise not available when required, that capital is not available when required, that unexpected geological results are encountered and that equipment failures, permitting delays or labor or contract disputes or shortages are encountered.

Information on other important economic factors or significant uncertainties that may affect components of the reserves data and the other forward looking statements in this release are contained in the Company’s Form 51-101F1 Statement of Reserves Data and Other Oil & Gas Information for the year ended December 31, 2025, the Company’s Management Discussion and Analysis and the Company’s Annual Information Form under “Risk Factors”, which are available under the Company’s profile at www.sedarplus.ca.

Note:

PART 5: ADDITIONAL INFORMATION RELATING TO RESERVES DATA

5.1 Undeveloped Reserves

The Company’s undeveloped reserves exist in the Caney shale of its interests in the Tishomingo Field in Oklahoma, U.S. Most of these reserves are designated within the undeveloped category because significant capital expenditures will be required in order to render these reserves capable of production.

The following tables disclose the proved undeveloped and probable undeveloped reserves from the Company’s current net interest in the Tishomingo Field that were first attributed in each of the most recent three financial years:

Plans for future development of these undeveloped reserves (based on Forecast Prices and Costs) are summarized below:

United States of America Properties

Tishomingo Field, Oklahoma

NSAI assigns 29,038 Mboe (Company Gross Working Interest share) Proved Undeveloped and 12,038 Mboe (Company Gross Working Interest share) Probable Undeveloped reserves to the Tishomingo Field. The Proved Undeveloped reserves are forecast to be recoverable from the drilling of 11 wells in 2026 and 17, 19 and 1 well in 2027, 2028 and 2029 respectively (7.84, 13.85, 12.20 and 0.97 net KGEI wells). The Probable Undeveloped reserves are forecast to be recoverable from the drilling of 10 wells in 2029, and 14 wells in 2030 respectively (6.05 and 4.87 net KGEI wells).

The production forecast is based on producing the existing wells and drilling the additional wells as listed above and applying the historical production behavior to the undeveloped well locations.

5.2 Significant Factors or Uncertainties

Estimates of economically recoverable oil and natural gas reserves (including natural gas liquids) and the future net cash flows therefrom are based upon a number of variable factors and assumptions, such as availability of capital to fund required infrastructure, commodity prices, production performance of the wells drilled, successful drilling of infill wells, the assumed effects of regulation by government agencies and future capital and operating costs. All of these estimates will vary from actual results. Estimates of the recoverable oil and natural gas reserves attributable to any particular group of properties, classifications of such reserves based on risk of recovery and estimates of future net revenues expected therefrom, will vary. The Company’s actual production, revenues, taxes, development and operating expenditures with respect to its reserves will vary from such estimates, and such variances could be material. Estimates of after-tax net present value are dependent on a number of factors including utilization of tax-loss carry forwards. In addition to the foregoing, other significant factors or uncertainties that may affect either the Company’s reserves or the future net revenue associated with such reserves include material changes to existing taxation or royalty rates and/or regulations, and changes to environmental laws and regulations.

Information on other important economic factors or significant uncertainties that may affect components of the reserves data and other oil and gas information contained in this Form 51-101F1 are contained in the Company’s Management Discussion and Analysis filed under the Company’s profile at www.sedarplus.ca and in the AIF under “Risk Factors”.

5.3 Future Development Costs

A summary of the estimated development costs deducted in the estimation of future net revenue attributable to various reserves categories and prepared under various price and cost assumptions are summarized in the following table. The Company expects to fund its estimated future development costs through some combination of internally generated cash flow and debt or equity financing. There can be no guarantee that funds will be available when required to proceed with the development on the schedule contemplated herein or that the Board of Directors of the Company will allocate funding to develop all of the reserves requiring development. Failure to develop such reserves could negatively impact future net revenue.

PART 6: OTHER OIL AND GAS INFORMATION

6.1 Oil and Gas Properties and Wells

The following discussion outlines the Company’s important properties, plants, facilities and installations:

United States

Tishomingo Field, Ardmore Basin, Oklahoma

In Oklahoma, the Company currently holds approximately 17,700 net acres of Caney shale acreage in the Tishomingo Field near Ardmore, OK. The Company originally drilled wells to the slightly deeper Woodford shale in this field. In April 2013, the Company sold some of its rights in the Tishomingo Field, keeping the rights to the Caney and the upper Sycamore formations, where it had previously drilled and tested two wells. Beginning in 2013, the Company began focusing primarily on developing the oily Caney shale. A subsequent transaction in 2015 resulted in the Company obtaining a 4.9% working interest in one section and participating in four Woodford shale horizontal wells which were completed in 2016. Over the years, the Company increased its net acreage position from about 12,500 to about 17,700 net acres currently. The Company plans to continue development drilling in this field with the objective of increasing production and proved reserves. The Company’s oil is trucked from the field and its wells are connected to a 3rd party gathering system, whose operator markets and sells the gas and NGL’s.

In 2025, the Company drilled 7 wells (6 were longer lateral wells) and completed 9 wells (2 were drilled in 2023). As of December 31, 2025, the Company has 45 completed Caney wells, a very small interest in one completed Sycamore well, and small interests in 4 Woodford wells, all of which are on production. Production averaged 4,013 BOEPD in 2025, with the production of 1.46 million oil equivalent barrels in 2025. KGEI’s 2025 year-end proved reserves were 40.8 million BOE, and its proved and probable reserves were 57.6 million BOE.

Oil & Gas Properties Associated with Reserves

As of December 31, 2025

Oil & Gas Properties Associated with Reserves

As of December 31, 2025

(1) Suspended wells may be capable of production but which, for a variety of reasons, including, but not limited to lack of markets or development are not placed on production at the present time. (2) Service wells are used for the disposal or injection of water or other in-field service operations related to oil and gas product.

6.2 Properties with No Attributed Reserves

The Company’s unproved properties, including those for which the Company expects its rights to explore, develop and exploit to expire within one year, are outlined in the following table.

Properties with no Attributed Reserves

As of December 31, 2025

6.3 Forward Contracts

The Company is not bound by any agreements which may impact the realization of future full market prices for its oil and gas production as described in this report, other than the financial commodity contracts listed below as of December 31, 2025.

The Company has no transportation obligations or commitments for future deliveries which exceed its expected related future production from proved reserves, as estimated using forecast prices and costs.

6.4 Tax Horizon

The Company does not expect to be required to pay federal and Oklahoma state income taxes in the immediate foreseeable future. Since California suspended the utilization of net operating losses until 2026, the Company is expected to be required to pay California state taxes during 2025 and 2026.

6.5 Costs Incurred

For the year ended December 31, 2025, the Company incurred costs related to its acquisition, exploration and development activities as outlined in the following table.

6.6 Exploration and Development Activities

The Company’s drilling and completion activity and results for the year ended December 31, 2025, are summarized in the following table. It should be noted that the data outlined in this table reflects those wells that the Company participated in and where the rig was released during the period.

The Company’s exploration and development activities are summarized as follows:

United States

During fiscal year 2025 KGEI drilled seven and completed nine Caney wells in its Tishomingo Field. The Company also participated with a very small interest in one Sycamore exploration well. The Company plans additional development drilling in the Tishomingo Field, OK, with the objective of increasing production and reserves.

PART 7: NOTES

The following definitions and guidelines are contained in Section 5.4 of Volume 1 of the Canadian Oil and Gas Evaluation Handbook (Second Edition, September 1, 2007) prepared jointly by The Society of Petroleum Evaluation Engineers (Calgary Chapter) and the Canadian Institute of Mining, Metallurgy & Petroleum (Petroleum Society) (the “COGE Handbook”) and have been prepared by the Standing Committee on Reserves Definitions of the CIM (Petroleum Society). Readers should consult the COGE Handbook for additional explanation and guidance. Certain other terms used in this Listing Application have the meanings assigned to them in NI 51-101 and accompanying Companion Policy 51-101 CP, adopted by the Canadian securities regulatory authorities.

Gross

Net

The following definitions apply to both estimates of individual reserves entities and the aggregate of reserves for multiple entities:

Reserve Categories

Reserves are estimated remaining quantities of oil and natural gas and related substances anticipated to be recoverable from known accumulations from a given date forward, based on:

Reserves are classified according to the degree of certainty associated with the estimates:

Development and Production Status

Each of the reserve categories (proved and probable) may be divided into developed and undeveloped categories:

In multi-well pools it may be appropriate to allocate total pool reserves between the developed and undeveloped categories or to subdivide the developed reserves for the pool between developed producing and developed non-producing. This allocation should be based on the estimator’s assessment as to the reserves that will be recovered from specific wells, facilities and completion intervals in the pool and their respective development and production status.

Levels of Certainty for Reported Reserves

The qualitative certainty levels referred to in the definitions above are applicable to individual reserve entities (which refers to the lowest level at which reserves calculations are performed) and to reported reserves (which refers to the highest level sum of individual entity estimates for which reserves are presented). Reported reserves should target the following levels of certainty under a specific set of economic conditions:

A quantitative measure of the certainty levels pertaining to estimates prepared for the various reserves categories is desirable to provide a clearer understanding of the associated risks and uncertainties. However, the majority of reserves estimates will be prepared using deterministic methods that do not provide a mathematically derived quantitative measure of probability. In principle, there should be no difference between estimates prepared using probabilistic or deterministic methods.

Forecast prices and costs

Future prices and costs that are:

The forecast summary pricing table identifies benchmark reference pricing that apply to the Company.

Product Type Disclosure

This statement includes references to sales volumes of “oil”, “natural gas”, and “barrels of oil equivalent” or “BOEs”. “Oil” refers to light crude oil and medium crude oil combined, and “natural gas” refers to shale gas, in each case as defined by NI 51-101. Production from our wells, primarily disclosed in this statement in BOEs, consists of mainly oil and associated wet gas. The wet gas is delivered via gathering system and then pipelines to processing plant where it is treated and sold as natural gas and NGLs.
