Alvopetro Energy Ltd. (TSXV: ALV) (OTCQX: ALVOF) ("Alvopetro" or the "Company") announces our reserves as at December 31, 2024 with total proved ("1P") reserves of 4.5 MMboe and total proved plus probable ("2P") reserves of 9.1 MMboe, increases of 65% and 5%, respectively, from December 31, 2023 . The before tax net present value discounted at 10% ("NPV10") of our 1P reserves increased 53% to $177.7 million and the NPV10 of our 2P reserves increased 6% to $327.8 million . We also announce risked best estimate contingent resources of 4.5 MMboe (NPV10 $110.0 million ) and risked best estimate prospective resources of 10.2 MMboe (NPV10 $208.9 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 26, 2025 with an effective date of December 31, 2024 (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 the Caburé and Murucututu natural gas fields and the Bom Lugar and Mãe-da-lua oil fields as well as Alvopetro's working interest share of remaining recoverable resources held by Alvopetro in the Murucututu natural gas field. With respect to Murucututu, Bom Lugar, and Mãe-da-lua, Alvopetro's working interest share is 100%. With respect to the unitized area (the "Unit") which includes our Caburé and Caburé Leste fields (collectively referred to as "Caburé" in this news release) and two fields held by our third-party partner in the Unit, Alvopetro's working interest share as of December 31, 2024 was 56.2%, with the remaining 43.8% held by our partner.

All references herein to $ refer to United States dollars, unless otherwise stated.

President & CEO, Corey C. Ruttan commented:

"Our 2024 year end reserves reflect a strong year for Alvopetro resulting from our successful redetermination increasing our Caburé Unit working interest from 49.1% to 56.2% and strong results from our 183-A3 well in the Caruaçu Formation on our 100% interest Murucututu project. These successes allowed us to commit to a higher level of base committed firm sales volumes with our offtaker, Bahiagás, for 2025 and further strengthens our disciplined capital allocation model, balancing returns to stakeholders and organic growth."

December 31, 2024 GLJ Reserves and Resource Report:

• After 2024 production of 0.7 MMboe, 1P reserves increased 65% to 4.5 MMboe, representing a 1P production replacement ratio ⁽¹⁾ of 372%. The increase was mainly due to the successful working interest redetermination at the Caburé field and increases on Caruaçu assigned reserves on our 100% Murucututu field following success on the 183-A3 well completion, somewhat offset by technical revisions related to the Gomo Formation.
• 2P reserve volumes increased 5% to 9.1 MMboe, representing a 2P production replacement ratio of 167% ⁽¹⁾ . The increase in 2P volumes was due to the higher working interest on the Caburé field following the redetermination, partially offset by 2024 production of 0.7 MMboe. At Murucututu, additional reserves associated with the Caruaçu reservoir were offset by technical revisions reducing reserves assigned to the Gomo Formation.
• With increased reserve volumes, 1P NPV10 increased 53% to $177.7 million and 2P NPV10 increased 6% to $327.8 million .
• Risked best estimate contingent resources decreased by 0.8 MMboe from 5.4 MMboe to 4.5 MMboe at December 31, 2024 with a NPV10 of $110.0 million , decreases from December 31, 2023 of 15% and 13% respectively. The decreases were associated with the migration of volumes to Reserves for the Caruaçu Formation.
• Risked best estimate prospective resources increased from 9.6 MMboe to 10.2 MMboe with a NPV10 of $208.9 million , increases of 6% and 13% respectively from December 31, 2023 .

PRICING ASSUMPTIONS – FORECAST PRICES AND COSTS

GLJ employed the following pricing and inflation rate assumptions as of January 1, 2025 , in the GLJ Reserves and Resources Report in estimating reserves and resources data using forecast prices and costs.

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 including our working interest share as of December 31, 2024 of the Unit (referred to herein as the Caburé natural gas field), our Murucututu natural gas project, as well as our Bom Lugar and Mãe-da-lua oil fields. 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 2024 fiscal year which will be filed on SEDAR+ ( www.sedarplus.ca ) by April 30, 2025 .

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, 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.

The future development costs for the Caburé field include Alvopetro's working interest share (56.2%) for two development wells in the proved category and an additional three development wells in the probable and possible categories.

The future development costs for the Murucututu field in the proved category include three development wells and a stimulation project at the 183-1 well. The probable category includes an additional two development wells .

The future development costs for Bom Lugar in the proved category include costs to stimulate the BL-06 well. Costs in the probable category also include one development well and costs for facilities upgrade. Future development costs at the Mãe-da-lua field relate to a stimulation of the existing well.

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

December 31, 2024 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 Contingent Resource Report for Murucututu assumes capital deployment starting in 2026 for the drilling and completion of wells with total project costs of $27.6 million and first commercial production in 2026. 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%; 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.

December 31, 2024 Murucututu Prospective Resources Information:

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)}

The GLJ Reserves and Resources Report for Murucututu prospective resources assumes capital deployment starting in 2026 for the drilling and completion of wells and pipeline expansion costs, first commercial production in 2027 and with total project costs of $75.6 million in Low case, $90.3 million in the Best case and $97.7 million in the High case. 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 has 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, 2024 will be included in the Company's annual information form for the year ended December 31, 2024 which will be filed on SEDAR+ ( www.sedarplus.ca ) on or before April 30, 2025 .

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, 2024 . 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.

Cabur   é   Working Interest

Alvopetro's working interest in the Caburé natural gas field is 56.2% as of December 31, 2024 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 the redetermination and the impact to each party's working interest. 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 has 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, 2024 will be contained in the Company's annual information form for the year ended December 31, 2024 which will be filed on SEDAR+ ( www.sedarplus.ca ) on or before April 30, 2025 .

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, 2024 will be contained in the Company's annual information form for the year ended December 31, 2024 which will be filed on SEDAR+ ( www.sedarplus.ca ) on or before April 30, 2025 .

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 (6Mcf/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", a metric commonly used in the oil and natural gas industry, which has been prepared by management. This term does not have a standardized meaning 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:
