Alvopetro Announces 2025 Year End Reserves Including a 79% Increase in 1P Reserves, 2P Production Replacement Ratio of 530% and 2026 Capital Plan

 Alvopetro Energy Ltd. (TSXV:ALV,OTC:ALVOF) (OTCQX: ALVOF) (‘Alvopetro’ or the ‘Company’) announces our reserves as at December 31, 2025 with total proved (‘1P’) reserves of 8.1 MMboe and total proved plus probable (‘2P’) reserves of 13.1 MMboe, increases of 79% and 43%, respectively, from December 31, 2024. The before tax net present value discounted at 10% (‘NPV10’) of our 1P reserves increased 38% to $245.6 million and the NPV10 of our 2P reserves increased 20% to $393.6 million. We also announce risked best estimate contingent resources of 3.8 MMboe (NPV10 $88.0 million) and risked best estimate prospective resources of 12.1 MMboe (NPV10 $264.3 million). The reserves and resources data set forth herein is based on an independent reserves and resources assessment and evaluation prepared by GLJ Ltd. (‘GLJ’) dated February 25, 2026 with an effective date of December 31, 2025 (the ‘GLJ Reserves and Resources Report’). 

The GLJ Reserves and Resources Report incorporates Alvopetro’s working interest share of remaining recoverable reserves held by Alvopetro in both Brazil and Canada. In Brazil, as of December 31, 2025, Alvopetro held a 100% working interest in the Murucututu natural gas field, a 56.2% working interest in the unitized area (the ‘Unit’) which includes our Caburé and Caburé Leste natural gas fields (collectively referred to as ‘Caburé’ in this news release) as well as a 100% working interest in two oil fields (Bom Lugar and Mãe-da-lua). Alvopetro has entered into an assignment agreement to dispose of these oil fields, the closing of which is subject to standard regulatory approvals, including approval of the ANP. In Canada, as of December 31, 2025, Alvopetro held a 50% working interest in 75 sections of land (23,539 net acres) focused on the Mannville Stack heavy oil play fairway in Western Saskatchewan.

President & CEO, Corey C. Ruttan commented:

‘Our 2025 year end reserves reflect another strong year for Alvopetro incorporating the results from our successful 183-D4 well in the Caruaçu Formation on our 100% interest Murucututu project, and our newly added Canadian assets.  Exiting 2025, we posted record Q4 production of 2,867 boepd, increasing further to 3,099 boepd in January, to start off 2026. We significantly strengthened our asset base in 2025, increasing 2P reserves by 43%, replacing 2025 production more than 5 times, and with a 2P reserve life index of 12.5 years. This further strengthens our disciplined capital allocation model, balancing returns to stakeholders and organic growth.’

December 31, 2025 GLJ Reserves and Resource Report:

After 2025 production of 0.9 MMboe, 1P reserves increased 79% to 8.1 MMboe, representing a 1P production replacement ratio(1) of 485%. The increase was mainly due to results from our 183-D4 well on our Murucututu field which commenced production in August 2025 and added an additional five proved undeveloped locations to our 1P reserves as well as newly added Canadian reserves of 0.3 MMboe.
2P reserve volumes increased 43% to 13.1 MMboe, representing a 2P production replacement ratio of 530%(1). Success on our 183-D4 well also contributed to the bulk of the increase to 2P reserves which includes eight undeveloped locations. In Canada, 0.7 MMboe of 2P reserves were assigned.
With increased reserve volumes, 1P NPV10 increased 38% to $245.6 million and 2P NPV10 increased 20% to $393.6 million.
2P reserves life index(1) of 12.5 years
Risked best estimate contingent resources decreased by 0.7 MMboe from 4.5 MMboe to 3.8 MMboe at December 31, 2025 with a NPV10 of $88.0 million, decreases from December 31, 2024 of 16% and 20% respectively. The decreases were associated with the migration of contingent resources to Reserves for the Caruaçu Formation at Murucututu.
Risked best estimate prospective resources increased from 10.2 MMboe to 12.1 MMboe with a NPV10 of $264.3 million, increases of 19% and 27% respectively from December 31, 2024. The increases were mainly due to additional prospective resource in the Caruaçu Formation at Murucututu adjacent to the assigned reserves area.

SUMMARY

December 31, 2025 Gross Reserve and Gross Resource Volumes: (1)(2)(3)(4)(5)(6)

Net Present Value Before Tax Discounted at 10%:(1)(2)(3)(4)(5)(6)(7)(8)

PRICING ASSUMPTIONS – FORECAST PRICES AND COSTS 

GLJ employed the following pricing and inflation rate assumptions as of January 1, 2026, in the GLJ Reserves and Resources Report in estimating reserves and resources data using forecast prices and costs.

2026 Capital Plan

Brazil

Our 2026 capital plan is designed to address the better than anticipated results from our 183-D4 well brought on production from our 100% interest Murucututu project in August 2025. In 2026, we have a multi-pronged facilities focused plan designed to increase our ability to deliver Murucututu production, and to be in a position to fully unlock the potential of this asset on a multi-year basis.

We plan to expand our Murucututu field production facility and pipeline offtake capacity to support an increase in our Murucututu field capacity from our current level of approximately 150 e3m3/d up to 600 e3m3/d.

In parallel, we plan to enhance our gas processing capability at our UPGN Caburé to accommodate increasing proportions of richer gas production from our Murucututu field, also targeting a total capacity of up to 600 e3m3/d.

In addition to these sales specified natural gas deliveries through the UPGN Caburé we are evaluating alternatives to deliver non-specified natural gas to additional offtakers. We plan to balance these opportunities with continued facilities enhancements and increasing Bahiagás sales to accommodate our longer-term growth objectives.

Our 2026 drilling and completions plan includes the sidetrack of one unfinished well from 2025 at Caburé. At Murucututu, our 2026 plan includes a recompletion of one well in the Gomo Formation and the drilling and completion of one new well targeting the Caruaçu Formation. We are also permitting a new drilling pad that can support the drilling of our planned Caruaçu development drilling plan updip of our highly successful 183-D4 well.

Our 2026 capital budget for these projects is $21 million. Once our facilities focused 2026 plan is completed, we will be positioned to accelerate our Murucututu multi-year development drilling plan in support of our longer-term growth objectives.

Canada

In the fourth quarter of 2025, we completed drilling our two additional earning wells to earn a 50% working interest in 47 additional sections of land. This expands our area of mutual interest with our partner, bringing our land position up to 75 gross sections (23,539 net acres), all targeting the Mannville stack heavy oil play fairway and the application of open hole multilateral drilling technology. We believe that this expanded land base can support the drilling of over 100 Tier 1 wells. In January 2026, we completed drilling two additional wells and now have a total of 8 (4.0 net) wells on production. Alvopetro’s share of these two gross (1.0 net) wells was budgeted at C$2.0 million in 2026. The pace of drilling of our broader development inventory will be executed in coordination with our partner and is expected to be largely dictated by anticipated oil prices.

GLJ RESERVES AND RESOURCES REPORT 

The GLJ Reserves and Resources Report has been prepared in accordance with the standards contained in the Canadian Oil and Gas Evaluation Handbook (the ‘COGE Handbook’ or ‘COGEH’) that are consistent with the standards of National Instrument 51-101 (‘NI 51-101’). GLJ is a qualified reserves evaluator as defined in NI 51-101. The GLJ Reserves and Resources Report was an evaluation of all reserves of Alvopetro in Brazil and Canada. In Brazil, this includes our working interest share as of December 31, 2025 of the Unit (referred to herein as the Caburé natural gas field), our Murucututu natural gas field, as well as our Bom Lugar and Mãe-da-lua oil fields. Alvopetro has entered into an assignment agreement to dispose of its interest in these oil fields, subject to regulatory approvals, and these properties are referenced below as ‘Oil Fields Held for Sale’. In Canada, the GLJ Reserves and Resources Report includes our 50% working interest in reserves focused on the Mannville Stack heavy oil play fairway in Saskatchewan. The GLJ Reserves and Resources Report also includes an evaluation of the gas resources of our Murucututu natural gas field.  In addition to the reserves assigned to our Murucututu field, contingent resource was assigned to the area in proximity to our existing Murucututu reserves, deemed to be discovered. The area mapped by 3D seismic west and north of the area defined as contingent was assigned prospective resource. Additional reserves and resources information as required under NI 51-101 will be included in the Company’s Annual Information Form for the 2025 fiscal year which will be filed on SEDAR+ (www.sedarplus.ca) by April 30, 2026.

Summary of After Tax Net Present Value of Future Net Revenue – $000s (1)(2)(3)(7)(8)

Future Development Costs (1)(2)(3)(7)(8)

The table below sets out the total development costs deducted in the estimation of future net revenue attributable to proved reserves, proved plus probable reserves and proved plus probable plus possible reserves (using forecast prices and costs), by field and by country, in the GLJ Reserves and Resources Report. Total development costs include capital costs for drilling and completing wells and for facilities but excludes abandonment and reclamation costs which are deducted separately in the computation of future net revenue.

The future development costs for the Caburé field include Alvopetro’s working interest share (56.2%) for side-tracking one unfinished well from 2025.

The future development costs for the Murucututu field in the proved category include the recompletion of one well in the Gomo Formation and the drilling and completion of six new wells targeting the Caruaçu Formation and one well targeting the Gomo Formation. Also included in the proved category are costs associated with upgrading the Murucututu field production facility and pipeline capacity to increase the overall field capacity from 150 e3m3/d up to 600 e3m3/d. The probable category includes two additional development wells, one targeting the Gomo Formation and one targeting the Caruaçu Formation.  

The future development costs for the Bom Lugar and Mãe-da-lua fields (currently held for sale) in the proved category include costs to stimulate the BL-06 well on the Bom Lugar field and the existing well at the Mãe-da-lua field . Costs in the probable category also include one development well and costs for a facilities upgrade at the Bom Lugar field.

The future development costs in Canada in the proved category include Alvopetro’s share of costs to drill four additional wells (2.0 net), one (0.5 net) of which was completed in January of this year. The probable category includes an additional four wells (2.0 net).

Alvopetro’s share of future development costs are summarized as follows:

December 31, 2025 Murucututu Contingent Resources Information:

Summary of Unrisked Company Gross Contingent Resources (1)(2)(5)(6)

Summary of Before Tax Net Present Value of Future Net Revenue of Unrisked Contingent Resources- $000s (1)(2)(5)(6)(7)(8)

The GLJ Reserves and Resources Report for Murucututu contingent resources assumes capital deployment starting in 2029 for the drilling and completion of wells with total project costs of $40.2 million and first commercial production in 2029. The information presented herein is based on company net project development costs. The recovery technology assumed for purposes of the estimate is based on established technologies utilized repeatedly in the industry.

There can be no certainty that the project will be developed on the timelines discussed herein. The project is based on a pre-development study. Development of the project is dependent on several contingencies as further described in this news release. Significant positive factors relevant to the estimate include existing production in close proximity, proximity to infrastructure, existing long-term gas sales agreement and corporate commitment to the project. Significant negative factors relevant to the estimate include reservoir performance and the economic viability of the project (with sensitivity to low commodity prices), access to and amount of capital required to develop resources at an acceptable cost, and regulatory approvals for planned activities including stimulations and new infrastructure developments.

Summary of Development Pending Risked Company Gross Contingent Resources(1)(2)(5)(6)

The GLJ Reserves and Resources Report estimates the Chance of Development as the product of two main contingencies associated with the project development, which are: 1) the probability of corporate sanctioning, which GLJ estimates at 95%; and 2) the probability of finalization of a development plan, which GLJ estimates at 95%. The product of these two contingencies is 90%.   As there is no risk related to discovery, the Chance of Commerciality for the contingent resource is therefore 90% which is the risk factor that has been applied to the Development Risked company gross contingent resources and the net present value figures reported below.

Summary of Unrisked Company Gross Prospective Resources (1)(2)(4)(6)

Summary of Before Tax Net Present Value of Future Net Revenue of Unrisked Prospective Resources – $000s (1)(4)(6)(7)(8)

See ‘Footnotes’ section at the end of this news release.

The GLJ Reserves and Resources Report for Murucututu prospective resources assumes capital deployment starting in 2029 for the drilling and completion of wells and pipeline expansion costs, with total project costs of $100.2 million in Low case, $127.0 million in the Best case and $136.0 million in the High case and first commercial production in 2029. The information presented herein is based on Company project development costs. The recovery technology assumed for purposes of the estimate is based on established technologies utilized repeatedly in the industry.

There can be no certainty that the project will be developed on the timelines discussed herein. Development of the project is dependent on several contingencies as further described in this news release. The project is based on a conceptual study. Significant positive factors relevant to the estimate include existing production in close proximity, proximity to infrastructure, existing long-term gas sales agreement and corporate commitment to the project. Significant negative factors relevant to the estimate include reservoir performance and the economic viability of the project (with sensitivity to low commodity prices), access to and amount of capital required to develop resources at an acceptable cost, and regulatory approvals for planned activities including stimulations and new infrastructure developments.

Summary of Development Risked Company Gross Prospective Resources(1)(2)(4)(6)

The GLJ Reserves and Resources Report estimates the Chance of Commerciality as the product between the Chance of Discovery and the Chance of Development. The Chance of Discovery of the prospective resources has been assessed at 90%, while the Chance of Development has been assessed as the same as for the Contingent Resources described above at 90%. The resulting Chance of Commerciality is 81%, which have been applied to the company gross unrisked prospective resources and the net present value figures reported below.

Oil and Natural Gas Reserves

The disclosure in this news release summarizes certain information contained in the GLJ Reserves and Resources Report but represents only a portion of the disclosure required under NI 51-101. Full disclosure with respect to the Company’s reserves as at December 31, 2025 will be included in the Company’s annual information form for the year ended December 31, 2025 which will be filed on SEDAR+ (www.sedarplus.ca) on or before April 30, 2026.

All net present values in this press release are based on estimates of future operating and capital costs and GLJ’s forecast prices as of December 31, 2025. The reserves definitions used in this evaluation are the standards defined by COGEH reserve definitions and are consistent with NI 51-101 and used by GLJ. The net present values of future net revenue attributable to the Alvopetro’s reserves estimated by GLJ do not represent the fair market value of those reserves. Other assumptions and qualifications relating to costs, prices for future production and other matters are summarized herein. The recovery and reserve estimates of the Company’s reserves provided herein are estimates only and there is no guarantee that the estimated reserves will be recovered. Actual reserves may be greater than or less than the estimates provided herein. 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 proved plus probable plus possible reserves.

Caburé Working Interest

Alvopetro’s working interest in the Caburé natural gas field is 56.2% as of December 31, 2025 and the date hereof. This working interest is subject to redetermination, the first of which was completed in April 2024. An independent expert (the ‘Expert’) was engaged in connection with the first redetermination to evaluate each party’s interpretation of respective working interest split. Following the Expert’s decision, Alvopetro’s working interest was increased from 49.1% to 56.2%. Alvopetro’s partner filed a notice of dispute with respect to the Expert’s decision, seeking to stay the redetermination procedure. Alvopetro subsequently filed a request for emergency arbitration before the International Chamber of Commerce (‘ICC’) seeking to make the Expert decision effective starting on June 1, 2024. In May 2024, Alvopetro received the decision of the emergency arbitrator (‘the Order’) wherein the arbitrator found in favour of Alvopetro, making the Expert decision effective June 1, 2024 until such time as the dispute is reviewed by and decided upon by an arbitral tribunal pursuant to the Rules of Arbitration of the ICC. The redetermination dispute proceeded to a full arbitration under the Rules of the ICC, however the timing and outcome of the full arbitration is uncertain and the resulting impact on the reserves and the net present value of future net revenue attributable to such reserves as presented herein may be material. In addition, future redeterminations may also have a material impact on Alvopetro’s reserves and future cash flows.

Contingent Resources

This news release discloses estimates of Alvopetro’s contingent resources and the net present value associated with net revenues associated with the production of such contingent resources as included in the GLJ Reserves and Resources Report. There is no certainty that it will be commercially viable to produce any portion of such contingent resources and the estimated future net revenues do not necessarily represent the fair market value of such contingent resources. Estimates of contingent resources involve additional risks over estimates of reserves. Full disclosure with respect to the Company’s contingent resources as at December 31, 2025 will be contained in the Company’s annual information form for the year ended December 31, 2025 which will be filed on SEDAR+ (www.sedarplus.ca)  on or before April 30, 2026.

Prospective Resources

This news release discloses estimates of Alvopetro’s prospective resources included in the GLJ Reserves and Resources Report. There is no certainty that any portion of the prospective resources will be discovered and even if discovered, there is no certainty that it will be commercially viable to produce any portion. Estimates of prospective resources involve additional risks over estimates of reserves. The accuracy of any resources estimate is a function of the quality and quantity of available data and of engineering interpretation and judgment. While resources presented herein are considered reasonable, the estimates should be accepted with the understanding that reservoir performance subsequent to the date of the estimate may justify revision, either upward or downward. Full disclosure with respect to the Company’s prospective resources as at December 31, 2025 will be contained in the Company’s annual information form for the year ended December 31, 2025 which will be filed on SEDAR+ (www.sedarplus.ca) on or before April 30, 2026.

BOE Disclosure

The term barrels of oil equivalent (‘boe’) may be misleading, particularly if used in isolation. A boe conversion ratio of six thousand cubic feet per barrel (6 Mcf/bbl) of natural gas to barrels of oil equivalence is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. All boe conversions in this news release are derived from converting gas to oil in the ratio mix of six thousand cubic feet of gas to one barrel of oil.

Other Metrics

This new release contains references to ‘production replacement ratio’ and ‘reserve life index’, metrics commonly used in the oil and natural gas industry, which have been prepared by management. These terms does not have standardized meanings and may not be comparable to similar measures presented by other companies, and therefore should not be used to make such comparisons.

‘Production replacement ratio’ is calculated by dividing the change in reserve volumes plus current year production by current year production. Alvopetro’s 1P production replacement ratio and 2P production replacement ratio in 2024 is calculated as:

‘Reserve life index’ is expressed in years and is calculated by dividing 2P reserve volumes by the Company’s annualized Q4 2025 production of 2,867 boepd, as follows:
