Mr. Henao went on to say, "Our 2026 guidance demonstrates a transition in our corporate lifecycle. We are moving beyond a steady-state profile by allocating capital to projects with immediate accretive returns, such as our brownfield initiatives and operational efficiencies. Our focus remains on creating shareholder value through disciplined growth that strengthens cash flow and enhances long-term returns."

The following table summarizes the financial highlights for the three months and years ended December 31, 2025 and 2024.

Financial Highlights for the three months ended December 31, 2025

• Revenue increased by 74% to $260,733 during the fourth quarter of 2025, compared with $150,158 in the fourth quarter of 2024. This growth was primarily driven by a 57% increase in the average realized gold price, an 8% rise in ounces sold and an increase of 219% in silver sales, equivalent to $7,702. Gold sales totaled $244,889 at an average realized price of $4,179 per ounce, up from $144,239 at an average realized price of $2,662 per ounce in the fourth quarter of 2024.
  
  
• Cost of sales increased by 62% to $155,256 during the fourth quarter of 2025, compared with $95,664 in the fourth quarter of 2024. This increase was mainly driven by: (i) higher gold prices, which increased the costs of purchasing ore from Bonanza Mining Partners ("BMP") in Nicaragua and Contract Mining Partners ("CMP") in Colombia by $42,152 or 129%, and (ii) overall increases in taxes and operating costs across the Company's operations, including taxes (VAT and royalties) of $13,109, higher depreciation and amortization of $4,234, labour expenses of $2,995, and materials and maintenance costs of $1,065.
  
  
• Gross Profit increased by 94% to $105,477 in the fourth quarter of 2025, compared with $54,494 in the same period of 2024. The increase was mainly driven by higher gold prices, combined with a slight increase in ounces of gold sold compared with the same period in the prior year.
  
  
• Profit for the period decreased by 59% to $9,413 or $0.03 per share during the fourth quarter of 2025, compared with $23,195 or $0.08 per share during the fourth quarter of 2024 due to the payment of $49,342 to resolve the dispute with DGI over unpaid VAT from the years 2019 to 2024.
  
  
• Adjusted EBITDA was $114,550 during the fourth quarter of 2025, up 101% from $56,895 in the fourth quarter of 2024. The increase was due to stronger gold and silver prices (57% and 101% respectively), alongside continued cost discipline across the Company's operations..
  
  
• Net cash flow generated by operating activities was down 32%, to $49,684 in the fourth quarter of 2025, compared with $73,221 in the fourth quarter of 2024 due to an increase in payments to suppliers of $44,015, taxes due to the one-time payment to the DGI of $49,342 and employees and social security agencies of $4,232 offset by an increase in receipts from sales of goods of $77,913.
  
  
• Net free cash flow for the three months ended December 31, 2025, was positive at $32,208, compared with $56,706 in the same period of 2024. The reduction is attributable to the payment of VAT to DGI in the fourth quarter of 2025
  
  
• Dividends Paid during the fourth quarter of 2025 was $7,362, consistent with the amount distributed in the fourth quarter of 2024.
  
  
• During the fourth quarter of 2025, the Company made capital investment³ of $34,111 in existing mines, and exploration and growth projects, compared with $27,316 in the fourth quarter of 2024; an increase of 25% The increase of $6,795 is due to increased exploration in the Nechí Alluvial and Hemco Properties, the details of which are described in Section 8 under the Capital Expenditures for the three months ended December 31, 2025.

Financial Highlights for the year ended December 31, 2025

• Revenue increased by 48% and totaled $799,674 during the year ended December 31, 2025, compared with $538,566 in the year ended December 31, 2024. The increase in revenue is due to a 46% increase in the average realized price of gold sold and a 4% increase in ounces of gold sold partially offset by a decrease of 4% in silver sales and 24% decrease in energy sales. Gold sales totaled $769,785 at an average realized price per ounce of gold sold of $3,474 in the year ended December 31, 2025, compared with sales of gold of $508,965 at an average realized price per ounce of gold sold of $2,387 in the year ended December 31, 2024.

• Cost of sales increased by 34%, to $473,420 in the year ended December 31, 2025, compared with $354,567 in the year ended December 31, 2024. The increase in costs is primarily due to: (i) the higher cost of purchasing ore from BMP in Nicaragua of $75,973 and $9,786 from purchasing ore from CMP in Colombia both due to higher gold prices; (ii) higher taxes and royalties of $17,232 (iii) higher labour costs of $9,880; and (iv) greater maintenance and materials costs of $5,400, offset by lower costs for services like leases and energy of $4,942

• Gross Profit increased by 77% to $326,254 in the year ended December 31, 2025, compared with $183,999 in the year ended December 31, 2024; due to a 48% increase in revenue, due to higher gold prices, which was partially offset by a 34% increase in cost of sales as explained above.

• Profit for the period was up by 68% to $144,984 or $0.49 per share during the year ended December 31, 2025, compared with $86,552 or $0.29 per share during the year ended December 31, 2024. The increase in profit is due to the increase in gross profit, partially offset by an increase in other expenses of $53,709 and an increase in administrative expenses of $1,498. In addition, as a result of the higher profit before taxes, current tax expenses increased by $35,869.

• Adjusted EBITDA was up 71% to $358,405 during the year ended December 31, 2025, compared with $210,099 during the year ended December 31, 2024, due to a 48% increase in revenue, offset by a 34% increase in cost of sales, and an increase of $1,498 in administrative expenses.

• ROCE was 56% as at December 31, 2025, compared with ROCE of 38% as at December 31, 2024. The increase is mainly attributable to a 71% higher Adjusted EBITDA for the trailing 12 months, driven by higher gold prices and a slight increase in production. Average capital employed increased by 25% due to higher investment of property, plant and equipment, and exploration projects, mainly associated with the acquisition of the 80% of the La Pepa Project not already owned. This trend is consistent with the Company's growth strategy and investment cycle, and will continue to be monitored to ensure sustainable returns over time.

• Net Debt was $(92,606) as at December 31, 2025, compared with $(70,483) as at December 31, 2024, due to 12% higher cash and cash equivalents of $108,005, together with 41% lower loans and other borrowings of $15,398, reflecting a strong cash position. The balance sheet remains conservatively structured, providing financial flexibility to support ongoing investments and future growth initiatives.

• Dividends Paid were up 8% to $29,772 during the year ended December 31, 2025, compared with $27,663 in the same period of 2024. The period over period increase is due to the fact that the dividend paid in the first quarter of 2024 was $0.0175 corresponding to the $0.07 annual dividend declared in 2023 and paid over four quarters with the final payment made in the first quarter of 2024.

• Net cash flows generated by operating activities were up 38% totaling $198,454 in the year ended December 31, 2025, compared with $144,192 in the same period of 2024. The Company's net free cash flow for the year ended December 31, 2025 totaled $138,649, up from $86,807 in the same period of 2024, due to higher receipts from sales of goods of $239,736 partially offset by greater payments to: suppliers of $106,375 and income tax of $66,941, including the one-time payment in Nicaragua to satisfy the tax dispute; and higher capital expenditures of $43,620 related to purchases of intangible assets and exploration expenditures.

• Capital investments were up 85% to $140,579 during the year ended December 31, 2025, as investments were made into existing mines and exploration and growth projects, compared with $75,919 in the year ended December 31, 2024. The increase is explained mainly by the acquisition of the remaining 80% interest in the La Pepa Project from Pan American Silver Corp. ("Pan American") and the construction of the extension of the tailings' impoundment facility at the Hemco Property.

2026 Guidance

For 2026, Mineros is providing consolidated gold production guidance of 213,000 to 233,000 ounces of gold. This represents an increase of 10,000 ounces relative to 2025 guidance. This increase is the result of a disciplined focus on "quick-return" ounces, prioritizing capital investment toward brownfield projects and operational efficiencies that can be brought online rapidly to maximize free cash flow in a robust commodity market.

2026 Operational & Cost Outlook

The Company's production and cost guidance reflects a commitment to maintaining healthy margins despite global inflationary pressures.

In 2026, the Hemco Property (Nicaragua) is expected to deliver solid performance with gold production guidance of 130,000-140,000 ounces. The Panama & Pioneer operations are expected to have an AISC range of $2,000-$2,100 per ounce. In addition, the Bonanza Mining Partners arrangement is expected to generate a 39%-41% AISC margin, supporting a resilient contribution profile

The following table presents the safety statistics for the year ended December 31, 2025, and the comparative period in 2024.

GROWTH AND EXPLORATION PROJECT UPDATES

The Company's exploration and growth is focused on the replacement and expansion of Mineral Resources and Mineral Reserves by completing further work at or near our operating mines, at our growth projects and at early-stage exploration targets on our under-explored property interests. We are achieving our goals through systematic exploration programs, which include surface mapping and sampling, geochemical data collection surveys, geophysical surveys and drilling.

A core component of the business strategy of the Company is to explore new targets and develop existing deposits at or near the operating mines, with the objective of increasing Mineral Resources and Mineral Reserves and advancing promising deposits towards development.

The company continues reviewing exploration targets at the Hemco property and analyzing its near-term potential, Porvenir deposit which is the most advanced target will remain under review, analysis and designing through the year. Two potential growth and exploration projects the Company is reviewing are the Porvenir Project and the Luna Roja Deposit, both located at the Hemco Property.

Hemco Property, Nicaragua

Near Mine Exploration, Hemco Property Expansion

Near mine exploration is focused on the current mining operations, the Panama Mine and the Pioneer Mine. Mineralization is related to an epithermal gold system associated with multiple quartz veins.

A diamond drill program totaling 170 holes and 33,396 metres was completed in 2025, achieving approximately 110% of the 2025 original drilling plan. The objective of this campaign was to increase the Mineral Resources and Mineral Reserves at the Panama Mine and the Pioneer Mine. In the fourth quarter of 2025, the drill program advanced at the Panama Mine and the Pioneer Mine, with 6,288 metres of drilling completed in 26 holes. A total of 5,262 metres were drilled at the Panama Mine and 1,026 metres at the Pioneer Mine.

For 2026, the Company has planned a diamond drilling campaign of approximately 25,000 metres to expand the current Mineral Resources and Mineral Reserves. A total of 16,000 metres is planned for the Panama Mine and 9,000 metres for the Pioneer Mine. This work is expected to cost approximately $3.6 million.

Mineros is advancing the update of the Mineral Resources and Mineral Reserves for the Panama Mine and Pioneer Mine, with publication expected in early 2026 through the Hemco Property NI 43-101 update.

Brownfield Exploration, Hemco Property Expansion

Brownfield exploration is centered on the Bonanza block, which encompasses the concession areas between the Panama Mine and the Pioneer Mine. The mineralization belongs to the same epithermal gold trend that comprises the Panama and Pioneer mines, characterized by multiple quartz veins.

A total of 25 holes totaling 6,342 metres of diamond drilling was completed in 2025, representing approximately 75% of the originally planned drilling campaign. In the fourth quarter of 2025, the drill program focused on two brownfield targets, Cleopatra and Orpheus, with 4,196 metres drilled across 14 holes.

The Company experienced delays in initiating the program, with brownfield drilling commencing in July 2025 following the full commissioning of two additional drill rigs.

For 2026, Mineros has planned an 15,200 metres diamond drilling campaign, progressing the Cleopatra and Orpheus initial drilling from 2025, and La Reforma north extension, as a continuation of the Company's established resource replacement program at the Panama and Pioneer mines. This drilling is expected to cost approximately $2.2 million.

Porvenir Project

The Porvenir Project is a pre-development stage project located 10.5km southwest of the existing Hemco Property facilities. Mineralization consists of a volcanic hosted gold-zinc-silver deposit with epithermal quartz veins of intermediate sulphidation.

The Company continues to advance the update of Mineral Resources and Mineral Reserves for the Porvenir Project, with prefeasibility study optimization results expected to be reported through an updated NI 43-101 technical report for the Hemco Property in early 2026.

For 2026, Mineros has planned a $1.5 million, 10,000-meter diamond drilling campaign focused on infill and step-out drilling close to areas scheduled for early mining, with the objective of reducing geological uncertainty and de-risking the first three years of the updated mine plan. The program is designed to improve confidence in grade continuity and geological interpretation, supporting mine planning and operational decision-making in the initial years of production.

Guillermina Deposit

The Guillermina Deposit is an epithermal zinc-gold-silver deposit, located four kilometres west of the Pioneer deposit and three kilometres North of the Porvenir Project.

A total of 17 holes totaling 3,362 metres of diamond drilling was completed in 2025, representing 168% of the originally planned program. Encouraging preliminary results during the third quarter of 2025 identified opportunities that supported advancing a portion of the planned 2026 drilling program into 2025. The additional drilling was completed to support the upgrade of Inferred Mineral Resources to the Indicated category. In the fourth quarter of 2025, a total of 1,328 metres was drilled across five holes.

No drilling is scheduled for Guillermina Deposit in 2026.

Mineros is planning to update the Mineral Resource estimate for the Guillermina deposit, with publication expected late in the first quarter of 2026 through the Hemco Property NI 43-101 update.

Leticia Deposit

The Leticia Deposit is an epithermal gold-silver-zinc deposit, located 500m northwest of the Porvenir Project.

A total of nine holes totaling 2,574 metres of diamond drilling was completed in 2025, representing 183% of the originally planned program. Positive preliminary results obtained during the third quarter of 2025 highlighted additional opportunities, leading to the advancement of part of the 2026 planned drilling program into 2025. The additional drilling was completed to support the upgrade of Inferred Mineral Resources to the Indicated category and to obtain representative material for metallurgical test work. In the fourth quarter of 2025, a total of 1,178 metres was drilled across four holes.

For 2026, Mineros has planned a $0.5 million, 3,200-meter diamond drilling campaign focused on infill drilling of current Inferred Mineral Resources, with the goal of upgrading them to the Indicated Mineral Resource category.

Mineros is planning to update the Mineral Resource estimate for the Leticia deposit, with publication expected in early 2026 through the Hemco Property NI 43-101 update.

San Antonio Deposit

The San Antonio Deposit is an epithermal gold-silver-zinc deposit, located 700m southwest of the Porvenir Project.

No drilling is scheduled for San Antonio Deposit in 2026.

Mineros is planning to re estimate the Mineral Resource for the San Antonio deposit, with publication expected in early 2026 through the Hemco Property NI 43-101 update.

Luna Roja Deposit

The Luna Roja deposit is a skarn gold system located 24 km southeast of the existing Hemco facilities. The Company is focused on expanding current mineral resources and identifying new targets surrounding the main deposit.

Recent activity has prioritized data evaluation and BMP-supported exploitation over direct drilling. Consequently, we are undergoing a regulatory review of our concessions. While we are managing the necessary administrative steps to ensure project viability, these processes introduce uncertainty regarding the timing and approval of future operational permits.

For 2026, no drilling activities have been scheduled for the Luna Roja deposit. Mineros continues to advance the update of the deposit's mineral resources, with publication expected in early 2026 through the update of the NI 43-101 technical report for the Hemco property.

Following the year-end closing analysis performed in December 2025, management concludes that there is no asset impairment.

Hemco Property Regional Exploration

Mineros' regional green-field exploration is focused on three areas with early-stage targets: Bonanza, Rosita and Siuna districts. The Bonanza district excludes the designated brownfield area known as the Bonanza block, see Brownfield Exploration, Hemco Property Expansion.

In 2025, a total of 6,541 metres of diamond drilling was completed in 35 drill holes, representing approximately 131% of the revised planned 2025 program. The objective of this campaign was reconnaissance drilling aimed at evaluating the potential continuity of mineralization. Drilling activities comprised 2,576 metres at the Constancia-Cottam target, 965 metres at the PisPis target, 1,278 metres at the Experiencia target and 1,722 metres at the Caballo Loco Target. In the fourth quarter of 2025, a total of 3,302 metres of drilling were completed in 16 holes.

The program exceeded the original plan primarily due to the completion of shorter drill holes than originally planned improving drilling productivity, which resulted in a higher number of metres drilled within the revised program scope.

In 2026, greenfield exploration activities will be focused over the three priority districts:

• Bonanza District: This district hosts targets characterized by gold-silver-zinc mineralization, as evidenced by historical mining, artisanal workings, and surface sampling.

• Rosita District: This district comprises targets with predominantly gold-silver mineralization identified from historical mining records, artisanal workings, surface sampling, and limited scout drilling.

• Siuna District: This district includes targets with demonstrated gold-silver mineralization identified through historical mining, artisanal activities, and surface sampling.

A $3.2 million, 22,000-meter drilling campaign is planned for 2026 to test targets across the three districts.

Nechí Alluvial Property, Colombia

Near Mine Exploration, Nechí Alluvial Property Expansion

At the Nechí Alluvial Property, Mineros is exploring for alluvial gold predominantly east of the Nechí River, where the Company is currently mining within quaternary alluvial sediments.

A total of 15,133 metres in 581 holes were completed in 2025, approximately 50% higher than the Company's original drilling plan. A total of 4,757 metres in 201 holes were drilled in the fourth quarter of 2025, 1,978 metres of infill drilling in the current production area, 2,025 metres are designed to expand the current Mineral Resources, and 754 metres of reconnaissance drilling at the Rio Cauca Target. From the total, 154 metres in 8 holes of ward drilling and 4,603 metres in 193 holes of sonic drilling were completed.

A 13,000 metre-drilling campaign is planned for 2026 costing approximately $4.1 million. Of the 13,000 metres, 10,000 metres are designed as infill drilling in production areas and to expanding the current Mineral Resources, 800 metres constitute reconnaissance drilling at the Río Cauca Target and 2,200 metres have been planned to test a number of greenfield targets.

La Pepa Property, Chile

The La Pepa Project is an advanced gold exploration project located in the Maricunga Gold Belt of the Atacama Region, Chile, approximately 800 km north of Santiago and 110 km east of Copiapó, at 4,200 metres above sea level in the Andes Mountains.

NON-IFRS AND OTHER FINANCIAL MEASURES

The Company has included certain non-IFRS financial measures and non-IFRS ratios in this news release. Management believes that non-IFRS financial measures and non-IFRS ratios, when supplementing measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS financial measures and non-IFRS ratios do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies. This data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. For a discussion of the use of non-IFRS financial measures and reconciliations thereof to the most directly comparable IFRS measures, see below.

EBIT, EBITDA and Adjusted EBITDA

The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use earnings before interest and tax ("EBIT"), earnings before interest, tax, depreciation and amortization ("EBITDA"), and adjusted earnings before interest, tax, depreciation and amortization ("Adjusted EBITDA"), which excludes certain non-operating income and expenses, such as financial income or expenses, hedging operations, exploration expenses, impairment of assets, foreign currency exchange differences, and other expenses (principally, donations, corporate projects and taxes incurred). The Company believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results because it is consistent with the indicators management uses internally to measure the Company's performance and is an indicator of the performance of the Company's mining operations.

The following table sets out the calculation of EBIT, EBITDA and Adjusted EBITDA to Net Profit for the three months and years ended December 31, 2025 and 2024:

Cash Cost

The objective of Cash Cost is to provide stakeholders with a key indicator that reflects as close as possible the direct cost of producing and selling an ounce of gold.

The Company reports Cash Cost per ounce of gold sold which is calculated by deducting revenue from silver sales, depreciation and amortization, environmental rehabilitation provisions and including cash used for retirement obligations and environmental and rehabilitation and sales of electric energy. This total is divided by the number of gold ounces sold. Cash Cost includes mining, milling, mine site security, royalties, and mine site administration costs, and excludes non-cash operating expenses. Cash Cost per ounce of gold sold is a non-IFRS financial measure used to monitor the performance of our gold mining operations and their ability to generate profit, and is consistent with the guidance methodology set out by the World Gold Council.

The following table provides a reconciliation of Cash Cost per ounce of gold sold on a by-product basis to cost of sales for the three months and years ended December 31, 2025, and 2024.

All-in Sustaining Costs

The objective of AISC is to provide stakeholders with a key indicator that reflects as closely as possible the full cost of producing and selling an ounce of gold. AISC per ounce of gold sold is a non-IFRS ratio that is intended to provide investors with transparency regarding the total costs of producing one ounce of gold in the relevant period.

The Company reports AISC per ounce of gold sold on a by-product basis. The methodology for calculating AISC per ounce of gold sold is set out below and is consistent with the guidance methodology set out by the World Gold Council. The World Gold Council definition of AISC seeks to extend the definition of total Cash Cost by deducting cost of sales of non-mining operations and adding administrative expenses, sustaining exploration, sustaining leases and leaseback and sustaining capital expenditures. Non-sustaining costs are primarily those related to new operations and major projects at existing operations that are expected to materially benefit the current operation. The determination of classification of sustaining versus non-sustaining requires judgment by management. AISC excludes current and deferred income tax payments, finance expenses and other expenses. Consequently, these measures are not representative of all the Company's cash expenditures. In addition, the calculation of AISC does not include depreciation and amortization cost or expense as it does not reflect the impact of expenditures incurred in prior periods. Therefore, it is not indicative of the Company's overall profitability. Other companies may quantify these measures differently because of different underlying principles and policies applied. Differences may also occur due to different definitions of sustaining versus non-sustaining.

The following table provides a reconciliation of AISC per ounce of gold sold to cost of sales for the three months and years ended December 31, 2025, and 2024.

Cash Cost and All-in Sustaining Costs by Operating Segment

The following table provides a reconciliation of Cash Cost per ounce of gold sold and AISC per ounce of gold sold by operating segment⁴ to cost of sales, for the three months and years ended December 31, 2025, and 2024.

Margin CMP & BMP

The margin between the All-In Sustaining Cost (AISC) of each operation and the average price of gold sold is a key indicator of operational profitability and financial health for a gold mining company. AISC represents the comprehensive cost to produce one ounce of gold, including direct mining costs, sustaining capital expenditures, corporate overhead, and other ongoing expenses necessary to maintain current production levels. By comparing the AISC of each operation to the average realized gold price during the reporting period, we can assess the profitability of each mine and the company as a whole.

Gold equivalent ("AuEq")(oz)

The Company calculates gold equivalent ounces to provide a measure that reflects the aggregate economic potential of the assets in question. The methodology employed for the calculation of equivalent ounces is as follows: Gold ounces produced and revenue derived from silver ounces sold is divided by the average realized price per ounce of gold sold. This approach captures the value contributed by both gold and silver production, thereby enabling a comprehensive evaluation of the asset's overall economic viability.

The formula utilized for this calculation is expressed as:

Gold equivalent ("AuEq") ounces = (Gold ounces produced + revenue derived from silver ounces sold) / average realized price per ounce of gold sold.

Net Free Cash Flow

The Company uses the financial measure "net free cash flow", which is a non-IFRS financial measure, to supplement information regarding cash flows generated by operating activities. The Company believes that in addition to IFRS financial measures, certain investors and analysts use this information to evaluate the Company's performance with respect to its operating cash flow capacity to meet recurring outflows of cash.

Net free cash flow is calculated as cash flows generated by operating activities less non-discretionary sustaining capital expenditures and interest and dividends paid related to the relevant period.

The following table sets out the calculation of the Company's net free cash flow to net cash flows generated by operating activities for the three months and years ended December 31, 2025, and 2024:

Return on Capital Employed ("ROCE")

The Company uses ROCE as a measure of long-term operating performance to measure how effectively management utilizes the capital it is provided. This non-IFRS ratio is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The calculation of ROCE, expressed as a percentage, is Adjusted EBIT (calculated in the manner set out in the table below) divided by the average of the opening and closing capital employed for the 12 months preceding the period end. Capital employed for a period is calculated as total assets at the beginning of that period, less total current liabilities.

Net Debt

Net Debt is a non-IFRS financial measure that provides insight regarding the liquidity position of the Company. The calculation of net debt shown below is calculated as nominal undiscounted debt including leases, less cash and cash equivalents. The following sets out the calculation of Net Debt as at December 31, 2025 and 2024.

Average Realized Price

The Company uses "average realized price per ounce of gold sold" and "average realized price per ounce of silver sold", which are non-IFRS financial measures. Average realized metal price represents the revenue from the sale of the underlying metal as per the statement of operations, adjusted to reflect the effect of trading at the holding company level (parent company) on the sales of gold purchased from subsidiaries. Average realized prices are calculated as the revenue related to gold and silver sales divided by the number of ounces of gold sold. The following table sets out the reconciliation of average realized metal prices to sales of gold and sales of silver for the three months and years ended December 31, 2025 and 2024:
