Operational Results and Outlook

Certain optimizations improved performance throughout 2025, resulting in record production in the fourth quarter of 2025 driven by strong performance at Sadiola and the CDI Complex. Sadiola delivered 57,191 ounces in the fourth quarter, demonstrating improved operating performance driven by higher-grade transitional and oxide ore from Sadiola Main Pit Stage 5 and Sekekoto West. Bonikro produced 33,279 ounces, reflecting a significant quarter-over-quarter increase following earlier stripping that enabled access to higher-grade material. Agbaou achieved a strong production of 26,534 ounces, supported by higher throughput and improved mining performance.

The Company’s key focus for 2026 is to continue implementing its optimization plans to capture incremental production gains and reduce operating costs across its portfolio, thereby increasing margins and cash flows. Alongside this, the Company’s key strategic priority is the completion of construction and the commencement of operations at the Kurmuk Project, expected in mid-2026, while continuing exploration efforts to extend mine life, and enhance operational flexibility across its operations.

As previously guided, the Company expects to produce between 385,000 and 425,000 ounces of gold in 2026 from its currently producing mines, and between 100,000 and 150,000 ounces of gold from the Kurmuk Project, which is expected to begin production in mid-2026. The range is driven by different ramp-up scenarios. The lower end represents a conservative case that assumes stable grid power is achieved in late Q3 (as opposed to mid-Q2), reflecting exogenous factors outside the Company’s control. The power utility remains committed to providing sufficient stable power by mid-Q2; accordingly, the Company’s objective is to deliver production closer to the midpoint or higher end of the range. Total production guidance, including contributions from Kurmuk, is expected to be 485,000 to 575,000 ounces of gold. This is consistent with the historical production profile of the Company’s existing operations of 375,000 to 400,000 ounces, with incremental increases driven by access to higher grades and ongoing operational improvements and expansions.

First quarter results are expected to put the Company well on-track towards its annual guidance, and strong EBITDA⁽¹⁾ margins are expected to continue to improve.

OPERATING RESULTS SUMMARY

The mine-site level cost of sales per ounce, cash costs⁽¹⁾, AISC⁽¹⁾ in the fourth quarter of 2025 were $1,942, $1,830, and $1,980 per ounce, respectively, reflecting the improved operational performance driven by Sadiola and the CDI Complex.

For 2026, the projected mine-site level cost of sales per ounce, cash costs⁽¹⁾, AISC⁽¹⁾ are expected to be between $1,945-2,160, $1,550-1,680 and $1,750-1,900 per ounce, respectively, based on a gold price assumption of $4,250 per ounce.

2025 Operational Results

Sadiola (80% interest), Mali 

Sadiola comprises the Sadiola (80% interest) open pit gold mine, located in the Kayes region of Mali, as well as the Korali-Sud open pit gold mine (65% interest), 15 kilometres south of the processing plant at Sadiola. The remaining ownership in Sadiola is retained by the Government of Mali.

For the three months ended December 31, 2025, Sadiola produced 57,191 ounces of gold, compared to the 54,210 ounces produced in the comparative prior year quarter. Production in the fourth quarter represents record quarterly production for the mine since the Company went public in 2023, demonstrating the improved operating performance expected to continue in 2026 and beyond.

Production was mainly supported by mining transitional and oxide ore from Sadiola Main Pit Stage 5 and oxides from Sekekoto, which provided higher grades and throughput. Strong production in the fourth quarter of 2025 was further supported by the continued mobilization of new equipment by the mining contractor and strong performance at the processing plant. Following continued mobilization of additional equipment by the mining contractor in the fourth quarter, further equipment additions were observed during the first quarter of 2026. Instrumentation upgrades at the process plant were commissioned and at full capacity starting mid-February 2026. In the interim, optimization initiatives implemented throughout 2025, including increased mining and processing of oxide ore and improved operational efficiency on the existing process plant circuit, resulted in throughput consistently exceeding the pre-automation baseline. This delivered a cumulative increase of approximately 361,000 tonnes for the year, which occurred primarily in the fourth quarter. These outcomes reflect stronger process control, improved instrumentation reliability, and a more stable operating regime.

The Company continues to advance the development and preparation of new projects with near-surface, medium- to high-grade oxide zones, including FE4, FE2.5, and Sadiola Main Stage 6, which are expected to contribute to gold production in the short and medium term. Furthermore, FE2 North and Tambali North extension projects were brought forward through ongoing exploration efforts to identify additional near-surface oxide discoveries. These targets form part of the Company’s 2026 high-grade exploration pipeline and are expected to enhance operational flexibility and potentially boost production in 2026 and beyond.

With rising mining volumes, improved fresh-ore preparation, and active improvement programs, Sadiola is well positioned to stabilize production and sustain stronger margins over the medium term.

As previously discussed, the Company is advancing studies to define the best strategy for the next phase of the mine’s expansion. Please refer to Sadiola Expansion Project below for further details. Along with the advancement of the growth strategy for Sadiola, the Company is advancing its energy program for the asset and is undertaking a staged and scalable approach, initially installing additional state-of-the-art diesel generators and control systems, followed by the implementation of a hybrid power solution sufficient to meet the power requirements of the Phase 1 expansion at reduced costs. Please refer to Sadiola Energy Program below.

Total cost of sales⁽⁴⁾ and AISC⁽¹⁾ for the quarter were $2,131 and $2,104, respectively, per gold ounce. As previously guided, AISC⁽¹⁾ for the fourth quarter continued the trend of material reductions as a result of increased production, mining sequencing and operational improvements. This represents a reduction from the third quarter, despite higher royalties driven by higher average gold prices. The estimated gold price impact on fourth quarter AISC as a result of higher royalties due to average gold prices of approximately $4,145 versus an average of approximately $3,460 in the third quarter amounts to over $100 per ounce, implying a substantial gold-price-adjusted reduction in AISC on a quarter-over-quarter basis.

Gold sales for the current quarter were mostly in line with production, with small differences attributable to timing of shipments.

Sadiola Expansion Project

Over the last several years, the Company has been advancing a strategy of optimization and expansion at the Sadiola Gold Mine. Initial efforts focused on stabilizing the operation, primarily related to the existing processing capacity of mostly oxide ores, followed by a phased expansion to process fresh ores. The objective is to increase production and cash flows in both the short and long term.

On December 21, 2025, the Company announced that it commenced operations and began processing ore through the fresh ore comminution circuit installed pursuant to the Phase 1 expansion at Sadiola, marking a significant milestone in the transformational growth strategy for this long-life asset. The Phase 1 expansion is aimed at increasing production, reducing costs and materially increasing cash flows through a phased expansion approach. The Phase 1 mill ramped up in the first quarter of 2026, alongside the completion of ancillary systems and power-supply upgrades. Further optimizations to the processing circuit, including instrumentation and automation upgrades, are planned for execution this year. Together, these initiatives are expected to improve operating performance, enhance overall processing rates, and reduce reagent consumption incrementally.

The Company has been advancing studies to define the best strategy for the next phase of the mine’s expansion. The initial conclusion of these studies was that adding a pre-leach thickener to the circuit allows the plant to process over 90% of the fresh ore in the feed, increasing operational flexibility and potentially increasing production. Given that a pre-leach thickener is required regardless of the selected expansion scenario, the Company decided to begin engineering and design in late 2025 to prepare for construction in 2026.

Allied concluded in the fourth quarter that the best execution strategy for expansion at Sadiola is to progressively optimize, develop, and expand the current processing plant and ancillary infrastructure, rather than build a new processing plant. This organic growth strategy allows for more efficient deployment of capital and management of execution risks, and it enables the same ultimate throughput of over 9 Mt/y of ore processed defined in the previous feasibility study, but with interim and organic steps at 7 Mt/y and 8 Mt/y. This strategy also allows the recovery improvement project and the energy program to be implemented progressively as throughput capacity expands, for further capital efficiency and returns. For 2026, the Company will advance the engineering and early works required for the 7 Mt/y step, together with the studies to increase recoveries, new tailings dam construction and solar farm earthworks and mobilization.

Sadiola Energy Program

Along with the advancement of the growth strategy for Sadiola, the Company is advancing its energy program for the asset and is undertaking a staged and scalable approach, initially installing additional state-of-the-art diesel generators and control systems, followed by the implementation of a hybrid power solution, with the deployment of more efficient medium-speed thermal units, and a photovoltaic plant with battery energy storage systems (“BESS”) sufficient to meet the power requirements of the Phase 1 expansion at reduced costs. The systems will then be scaled up to satisfy the energy needs of the next phase expansion, providing Sadiola with a flexible power solution capable of meeting its ultimate power needs, while being self-reliant, efficient and cost-effective.

Sadiola Exploration

Since acquiring the Sadiola Project in 2021, Allied has identified over 15 million tonnes of economic oxide mineralization within the near-mine footprint, significantly enhancing the oxide resource base critical for the existing and planned processing infrastructure. Ongoing exploration activities at Sadiola Main, Tambali, Sekekoto West, FE3/4, FE2 Trend and TK1 support Allied’s strategy to leverage the existing resources, known mineralization trends and infrastructure to maximize production and cash flows in the short to medium term.

On October 29, 2025, Allied presented results of the exploration programs carried out over the Sadiola property during 2025. The Company’s five-year exploration goal for Sadiola is to reach over 14 million ounces of Mineral Resources, representing a sequential target of over 3.5 million ounces of new Mineral Resources in addition to the current inventory. The objective includes adding approximately 1.0 million ounces of new oxide, which, in turn, supports Sadiola’s medium-term and long-term expansion strategy, providing upside and optionality. Exploration drilling has intersected significant new zones and extensions at Sekekoto West/S12, Tambali, FE2 Trend, and FE3/4 Trend with Sekekoto West and the southern part of the FE2 Trend (FE2.5) potentially providing short-term, new and more proximal high-grade oxide resources for the Sadiola mill as mining at Korali Sud winds down. Mineralization remains open along strike and at depth across all four target areas. Select highlights from the news release (see Allied Gold’s press release dated October 29, 2025 available at alliedgold.com for full details) include:

• Sekekoto West/S12: 33.0 metres @ 15.23 g/t Au (SARC 1699) and 25.0 metres @ 11.90 g/t Au (SARC1695)
• Tambali: 12.6 metres @ 18.87 g/t Au (SADD181) and 6.7 metres @ 8.74 g/t Au (SADD264)
• FE2 Trend: 3.0 metres @ 28.19 g/t Au (SARC2318) and 8.0 metres @ 6.55 g/t Au (SARC2321)
• FE3/4 Trend: 18.0 metres @ 10.68 g/t Au (SARC1957) and 20.0 metres @ 5.53 g/t Au (SARC1948)

In 2026, Sadiola will see continued efforts with five drills dedicated to continue testing for, and extending, the gold mineralized structures at Sadiola Main, Tambali, FE2 Trend, Sekekoto Trend, FE3/FE4, TK1, Mandakoto and Kouloukan with an initial 2026 budget of $6.2 million. The exploration is focused on both oxide and shallow fresh mineralization with a preference for oxide gold mineralization in the near term. Oxide ore is favored in the short term as it provides the plant with relatively inexpensive, high-quality ounces. The horizontal and down-dip/down-plunge limits of these systems are still open and as such, expectations of ongoing discovery/additions are high.

Bonikro (89.89% interest), Côte d’Ivoire

The Bonikro gold mine is an open pit gold mine located in the Oumé region of Côte d’Ivoire (“Bonikro” or “Bonikro Mine”). The remaining ownership is split between the Government of Côte d’Ivoire (10%) and a local minority shareholder (0.11%).

Bonikro is contiguous to Agbaou, and together comprise the CDI Complex, with the two processing plants located only 20 km from each other. The combined milling capacity and existing infrastructure including water supply dams, tailings storage facilities, access and site roads, power supply and accommodation facilities provides optionality and significant synergies for the future.

Bonikro comprises two separate mining licences (the Bonikro Licence and Hiré Licence), although integrated as a single operation.

Bonikro produced 33,279 ounces of gold during the three months ended December 31, 2025, compared with 20,259 ounces produced in the comparable quarter of the previous year. For the fourth quarter, ore feed and grades were in line with plan, with slightly higher recoveries. Production in the fourth quarter was substantially increased from the previous quarter, benefiting from access to higher-grade ore due to the stripping completed earlier in the year. This performance builds on the operational improvements demonstrated throughout the year and is expected to continue into 2026, driven by the benefits of completing the stripping of pushback 5 in 2025, as well as other operational improvements.

For costs, as expected and guided, Bonikro’s sustaining capital and AISC⁽¹⁾ continued to be impacted by capitalized stripping at PB5. Stripping activities conducted in 2025, will improve production and costs for upcoming years, as high grade ore will be exposed while significantly lower waste removal will be required.

Hiré Exploration

In the fourth quarter, drilling at Hiré focused on testing for oxides along the eastern extension of the Chapelle orebody and sterilization drilling to extend a waste dump near the Agbale open pit. In total 36 holes comprising 3,701.4 metres were drilled with the bulk of the holes completed with an RC drill.

Oumé Exploration

No exploration drilling was conducted over the Oumé area at the northern end of the Properties during the quarter. However, 27 geotech and hydro geology holes totalling 3,240.5 metres were completed in support of Mineral Resource and Mineral Reserve estimation studies. Prospecting and mapping were advanced over the Oumé area in Q4, with a focus on gathering data over specific Au-in-soil anomalies, interpreted structures and induced polarization anomalies with a goal to test at least 5 new target areas in the first half of 2026.

Agbaou (85% interest), Côte d’Ivoire

Agbaou is an open pit gold mine, located in the Oumé region of Côte d’Ivoire. The remaining ownership is split between the Government of Côte d’Ivoire (10%) and the SODEMI development agency (5%).

Agbaou is contiguous to Bonikro, and together comprise the CDI Complex, with the two processing plants located only 20 km from each other. The combined milling capacity and existing infrastructure including water supply dams, tailings storage facilities, access and site roads, power supply and accommodation facilities provides optionality and significant synergies for the future.

Agbaou produced 26,534 ounces of gold during the three months ended December 31, 2025, compared to 25,163 ounces in the corresponding quarter of the previous year. Production in the fourth quarter focused on higher-grade fresh ore from the West pits and medium-grade oxide ore from the South and North pits. Ore mined was in line with plan, consistent with the previously outlined strategy to advance waste stripping in earlier quarters. This enabled access to higher ore tonnage and increased throughput at the process plant in the fourth quarter and into 2026. Continued stripping of the West pits is expected to provide access to ore to support the 2026 production, including securing access to higher-grade ore in the first quarter of 2026, ahead of the start of the rainy season.

Costs for the fourth quarter, as anticipated, began decreasing, as the waste removal at WP 7 until the third quarter, benefited access to oxide ore in the fourth quarter of 2025 which had significantly less stripping, along with the successful implementation of a centralized management model.

The Company has now succeeded in implementing a centralized management model for both mines in CDI, streamlining processes, optimizing resources, and enhancing service delivery for sustainable growth, and lowering AISC⁽¹⁾. The benefits of the centralized contractor model and the Hub-and-Spoke structure implemented are becoming more evident, enabling improved agility in managing shared resources and coordinating recovery efforts across sites. These enablers will be further embedded in the coming months as the Company transitions from initiation to full execution. Looking ahead, execution discipline will remain central to delivering value in the second half. With deeper integration of the Hub-and-Spoke model, continued focus on plant optimization, and improved mining flexibility.

In addition to operational factors, the increased waste removal in 2025 allows for less reliance on short-term resource conversion to support production levels in 2026, creating a bridge to focus additional exploration spending at Agbaou on more transformational targets aimed to add ounces and with an objective to increase mine life at Agbaou by four to six years, with the completion of the first stage exploration program in 2026.

Agbaou Exploration

Allied is actively pursuing opportunities to extend the mine life by increasing Mineral Reserves through sustained drilling and other exploration efforts. In the fourth quarter of 2025, Allied completed 49 holes totalling 9,883.2 metres with up to five drills operating. These holes tested the down-dip extensions of known gold-bearing ore bodies and in one case, testing of a new gold zone. This sustained effort, which commenced in July 2025, comprises a minimum of 166 holes totalling 35,072 metres with a goal of adding several more years of mine life. This work program is approximately 52% completed and scheduled to finish near the end of the first quarter of 2026.

Looking forward to 2026, testing of the known zones to depth will continue along with testing for oxide gold zones along strike of known deposits and new targets outside of the compensation boundaries.

Kurmuk

The Company continues to track well against plan, both in terms of physical completion and spend, while achieving key milestones and progress during the fourth quarter of 2025.

The project is progressing well, with procurement and logistics of critical items substantially completed at year-end. The key focus during the quarter was on logistics for transporting equipment and materials to the site and ramping up steel and mechanical erection at the crushing circuit and the processing plant. Mining activities at Ashashire and Dish Mountain are progressing according to plan, with the objective of building at least three months worth of ore stockpiles to support the start of operations in mid-2026. Kurmuk continued mechanical activities throughout the first quarter, progressing the remaining earthworks at the tailings storage facility and haulage road, and advancing piping and electrical installation, other infrastructure, and ancillary facilities. The Ethiopian Electrical Power Company is advancing the power line construction, which is expected to be completed before commissioning. Pre-commissioning activities are planned to begin at the start of the second quarter, with the first gold expected in mid-2026.

The key focus during the first quarter 2026 and the rest of the year is the completion and close-out of all remaining engineering and procurement activities, with particular emphasis on finalizing outstanding fabrication works and concluding all logistics arrangements for the transport of equipment, materials, and other long-lead items to site. This includes managing international and local supply chains, final inspections, expediting of critical items, and coordination of delivery schedules to align with site readiness and construction sequencing. Mobilization of the electrical, control and instrumentation contractor occurred in the first quarter of 2026, with the commencement of electrical, control and instrumentation work across the process plant and associated infrastructure areas. In parallel, piping installation will commence and ramp up across key plant circuits, enabling progressive completion of mechanical scopes and supporting downstream pre-commissioning activities. These activities will be closely coordinated with ongoing structural, mechanical, piping, and plate works to ensure efficient interface management across all work fronts. Bulk mining activities, initiated in the third quarter of 2025, will continue to ramp up in line with the production schedule, supporting the build-up of run-of-mine stockpiles and ensuring operational readiness for plant commissioning. The crushing circuit remains on track for early completion, which is critical to ensuring sufficient ore availability to support the targeted mid-year first gold milestone. Focus will be placed on achieving mechanical completion, testing, and handover of the crushing facilities to enable timely integration into the overall commissioning sequence. Overall construction activity is expected to reach peak levels, approximately 3,000 people, during the first quarter of 2026, with multiple disciplines progressing in parallel across the process plant, infrastructure, tailings, and mining areas. This peak period will be characterized by intensified site activity, increased manpower levels, and a strong focus on productivity, safety performance, quality control, and schedule adherence to ensure the project remains firmly on track to achieve its key operational milestones. Safety is the primary focus area during this period.

Pre-commissioning activities are planned to start at the beginning of the second quarter, with first gold expected for mid-2026. The Company expects Kurmuk to produce an average of 290,000 ounces per year for the first four years and 240,000 ounces per year on average for the mine’s life, with AISC⁽¹⁾ below $950 per ounce.

Along with the advancement of engineering for the project and as previously disclosed, the Company completed a review of the capacity of the processing plant in consideration of the ore inventory and the exploration progress at Dish Mountain, Ashashire and Tsenge. Allied made a strategic decision to maximize the operational flexibility for Kurmuk since the start of operations, and is now targeting an average processing capacity of up to 6.4 Mt/y. This increased flexibility is being incorporated into the project execution, with subsequent modifications to the leaching circuit expected to be deployed in the future years to increase fresh ore recoveries. The enhancements and optimizations are expected to make Kurmuk a stronger, de-risked operation upon commencement of production, providing upside and operational flexibility, aligning with the company’s long-term strategy of maximizing value at each of the Company’s assets.

Kurmuk Project Exploration

On November 27, 2025, Allied presented results of the exploration programs carried out over the Kurmuk Property during the period from mid 2024 to the middle of November 2025. The Company’s five-year exploration goal for Kurmuk is to reach 5 million ounces of Mineral Resources, representing a sequential target of over 1.5 million ounces of new Mineral Resources in addition to the current inventory. The objective includes adding at least 0.5 million ounces of new Mineral Resources within 10 km of the mill, to sustain or exceed the initial gold production levels of approximately 290,000 ounces per annum. The exploration plan considers expanding on the existing Mineral Resources near both the Ashashire and Dish Mountain deposits, advancing exploration at Tsenge utilizing a combination of geophysical surveys, trenching and drilling with a focus on higher-grade and advancing exploration at three other prospects in the property. At both Dish Mountain and Ashashire, drilling continues to intersect lateral and vertical extensions of the deposits, as the limits to the mineralized system remain open. A significant amount of highly successful drilling and trenching was also carried out at Tsenge, confirming the strike extents of the gold-bearing system and depth extensions of the Hiccup Hill and Setota mineralized lenses, located at the southern end of the 9 km long Tsenge target. A first-pass drill program, which was completed over the Urchin Prospect located adjacent to the Ashashire haul road, yielded positive results and will require a follow-up drill program. Select exploration highlights from this news release (see Allied Gold’s press release dated November 27, 2025 available at alliedgold.com for full details) include:

• Dish Mountain: 12.6 metres @ 2.93 g/t Au (DMDD774), 16.0 metres @ 2.61 g/t Au (DMDD765) and 9.3 metres @ 3.35 g/t Au (DMDD752)
• Tsenge – Hiccup Hill: 16.4 metres @ 13.0 g/t Au (TSDD041) and 10.0 metres @ 5.96 g/t Au (in trench TSCH012)
• Tsenge – Setota: 10.5 metres @ 1.85 g/t Au (TSDD036) and 20.0 metres @ 1.11 g/t Au (TSDD036)
• Urchin: 5.0 metres @ 3.47 g/t Au (ASRC031) and 4 metres @ 10.88 g/t Au (in trench URTR09)

Summary of Capital Expenditures

All expenditures associated with Kurmuk for the period are classified as Expansionary in nature, including exploration activities.

FINANCIAL SUMMARY AND KEY STATISTICS

Key financial operating statistics for the year ended December 31, 2025 are outlined in the following tables.

Net cash generated from operating activities for the three months ended December 31, 2025 was $189.3 million. This compares to $50.9 million in the prior year comparative quarter. Current period cash from operating activities was positively impacted by significantly higher gold sales and higher realized gold prices. Prior year cash flows were further negatively impacted by the settlement of claim matters and higher income taxes paid. Working capital impact for the quarter is related to normal course movements in inventory (including stockpiles) and timing of accounts payable, along with year-end accruals.

Operating cash flows before income tax paid, government settlements and movements in working capital for the three months ended December 31, 2025 increased significantly, at an inflow of $227.1 million compared with the prior year comparative quarter inflow of $141.0 million. This was due to higher gold sales and higher realized gold prices. The impact of higher sales was partially offset by lower proceeds from stream arrangements and prepays in the current period.

As at December 31, 2025, the Company had cash and cash equivalents of $479.8 million, compared with $225.0 million as at December 31, 2024.

END NOTES

NON-GAAP FINANCIAL PERFORMANCE MEASURES

The Company has included certain non-GAAP financial performance measures and ratios to supplement its Consolidated Financial Statements, which are presented in accordance with IFRS, including the following:

• Cash costs per gold ounce sold;
• AISC per gold ounce sold;
• Gross profit excluding DDA;
• Sustaining, Expansionary and Exploration Capital Expenditures;
• Adjusted Net Earnings (Loss) and Adjusted Net Earnings (Loss) per share; and
• EBITDA and Adjusted EBITDA

The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company.

Non-GAAP financial performance measures, including cash costs, AISC, Adjusted AISC, Gross profit excluding DA, Sustaining, Expansionary and Exploration Capital Expenditures, Adjusted Net Earnings (Loss), Adjusted Net Earnings (Loss) per Share, EBITDA and Adjusted EBITDA, do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies. Non-GAAP financial performance measures are intended to provide additional information, and should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS and are not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

Management’s determination of the components of non-GAAP financial performance measures and other financial measures are evaluated on a periodic basis, influenced by new items and transactions, a review of investor uses and new regulations as applicable. Any changes to the measures are described and retrospectively applied, as applicable. Subtotals and per unit measures may not calculate based on amounts presented in the following tables due to rounding.

The measures of cash costs and AISC, along with revenue from sales, are considered to be key indicators of a Company’s ability to generate operating earnings and cash flows from its mining operations. This data is furnished to provide additional information and is a non-GAAP financial performance measure.

CASH COSTS PER GOLD OUNCE SOLD

Cash costs⁽¹⁾ include mine site operating costs such as mining, processing, administration, production taxes and royalties which are not based on sales or taxable income calculations. Cash costs exclude DDA, exploration costs, accretion and amortization of reclamation and remediation, and capital, development and exploration spend. Cash costs include only items directly related to each mine site, and do not include any cost associated with the general corporate overhead structure.

The Company discloses cash costs because it understands that certain investors use this information to determine the Company’s ability to generate earnings and cash flows for use in investing and other activities. The Company believes that conventional measures of performance prepared in accordance with IFRS do not fully illustrate the ability of its operating mines to generate cash flows. The most directly comparable IFRS measure is cost of sales. As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS and, therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

Cash costs are computed on a weighted average basis, with the aforementioned costs, net of by-product revenue credits from sales of silver, being the numerator in the calculation, divided by gold ounces sold.

AISC PER GOLD OUNCE SOLD

AISC figures are calculated generally in accordance with a standard developed by the World Gold Council (“WGC”), a non-regulatory, market development organization for the gold industry. Adoption of the standard is voluntary, and the standard is an attempt to create uniformity and a standard amongst the industry and those that adopt it. Nonetheless, the cost measures presented herein may not be comparable to other similarly titled measures of other companies. The Company is not a member of the WGC at this time.

AISC include cash costs (as defined above), mine sustaining capital expenditures (including stripping), sustaining mine-site exploration and evaluation expensed and capitalized, and accretion and amortization of reclamation and remediation. AISC exclude capital expenditures attributable to projects or mine expansions, exploration and evaluation costs attributable to growth projects, DA, income tax payments, borrowing costs and dividend payments. AISC includes only items directly related to each mine site, and do not include any cost associated with the general corporate overhead structure. As a result, Total AISC represent the weighted average of the three operating mines, and not a consolidated total for the Company. Consequently, this measure is not representative of all of the Company’s cash expenditures.

Sustaining capital expenditures are expenditures that do not increase annual gold ounce production at a mine site and excludes all expenditures at the Company’s development projects as well as certain expenditures at the Company’s operating sites that are deemed expansionary in nature, such as the Sadiola Phased Expansion and the construction and development of Kurmuk. Exploration capital expenditures represent exploration spend that has met criteria for capitalization under IFRS.

The Company discloses AISC, as it believes that the measure provides useful information and assists investors in understanding total sustaining expenditures of producing and selling gold from current operations, and evaluating the Company’s operating performance and its ability to generate cash flow. The most directly comparable IFRS measure is cost of sales. As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

AISC are computed on a weighted average basis, with the aforementioned costs, net of by-product revenue credits from sales of silver, being the numerator in the calculation, divided by gold ounces sold.

The following tables provide detailed reconciliations from total costs of sales to cash costs and AISC. Subtotals and per unit measures may not calculate based on amounts presented in the following tables due to rounding.

GROSS PROFIT EXCLUDING DDA

The Company uses the financial measure “Gross Profit excluding DDA” to supplement information in its financial statements. The Company believes that in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and analysts use this information to evaluate the Company’s performance.

Gross profit excluding DDA is calculated as Gross Profit plus DDA.

The Company discloses Gross Profit excluding DDA because it understands that certain investors use this information to determine the Company’s ability to generate earnings and cash flows. The Company believes that conventional measures of performance prepared in accordance with IFRS do not fully illustrate the ability of its operating mines to generate cash flows. The most directly comparable IFRS measure is Gross Profit. As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

The reconciliation of Gross Profit to Gross Profit Excluding DDA can be found on pages 6, 9, and 11 of this press release.

ADJUSTED NET EARNINGS (LOSS) AND ADJUSTED NET EARNINGS (LOSS) PER SHARE

The Company uses the non-GAAP financial measures “Adjusted Net Earnings (Loss)” and the non-GAAP ratio “Adjusted Net Earnings (Loss) per share” to supplement information in its financial statements. The Company believes that in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and analysts use this information to evaluate the Company’s performance.

Adjusted Net Earnings (Loss) and Adjusted Net Earnings (Loss) per share are calculated as Net Earnings (Loss) attributable to Shareholders of the Company, excluding non-recurring items, items not related to a particular periods and/or not directly related to the core mining business such as the following, with notation of Gains (Losses) as they would show up on the financial statements.

• Gains (losses) related to the reverse takeover transaction events and other items,
• Gains (losses) on the revaluation of historical call and put options,
• Unrealized Gains (losses) on financial instruments and embedded derivatives,
• Write-offs (reversals) on mineral interest, exploration and evaluation and other assets,
• Gains (losses) on sale of assets,
• Unrealized foreign exchange gains (losses),
• Share-based (expense) and other share-based compensation,
• Unrealized foreign exchange gains (losses) related to revaluation of deferred income tax asset and liability on non-monetary items,
• Deferred income tax recovery (expense) on the translation of foreign currency inter-corporate debt,
• One-time tax adjustments to historical deferred income tax balances relating to changes in enacted tax rates,
• Non-recurring provisions,
• Any other non-recurring adjustments and the tax impact of any of these adjustments calculated at the statutory effective rate for the same jurisdiction as the adjustment.

Non-recurring adjustments from unusual events or circumstances are reviewed from time to time based on materiality and the nature of the event or circumstance.

Management uses these measures for internal valuation of the core mining performance for the period and to assist with planning and forecasting of future operations. Management believes that the presentation of Adjusted Net Earnings (Loss) and Adjusted Net Earnings (Loss) per share provide useful information to investors because they exclude non-recurring items, items not related to or not indicative of current or future periods’ results and/or not directly related to the core mining business and are a better indication of the Company’s profitability from operations as evaluated by internal management and the board of directors. The items excluded from the computation of Adjusted Net Earnings (Loss)⁽¹⁾ and Adjusted Net Earnings (Loss)⁽¹⁾ per share, which are otherwise included in the determination of Net Earnings (Loss) and Net Earnings (Loss) per share prepared in accordance with IFRS, are items that the Company does not consider to be meaningful in evaluating the Company’s past financial performance or the future prospects and may hinder a comparison of its period-to-period profitability.

The most directly comparable IFRS measure is Net Earnings (Loss). As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

The reconciliation of Net Loss to attributable to Shareholders of the Company to Adjusted Net Earnings can be found on page 13 of this press release and in the Company’s MD&A in Section 1: Highlights and Relevant Updates, under the Summary of Financial Results.

EBITDA AND ADJUSTED EBITDA

The Company uses the financial measures “EBITDA” and “Adjusted EBITDA” to supplement information in its financial statements. The Company believes that in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and analysts use this information to evaluate the Company’s performance.

EBITDA is calculated as Net Earnings (Loss), plus Finance Costs, DDA, Current income tax expense and Deferred income tax expense. Adjusted EBITDA calculated is further calculated as EBITDA, excluding non-recurring items, items not related to a particular periods and/or not directly related to the core mining business such as the following, with notation of Gains (Losses) as they would show up on the financial statements.

• Gains (losses) on the revaluation of historical call and put options,
• Unrealized Gains (losses) on financial instruments and embedded derivatives,
• Write-offs (reversals) on mineral interest, exploration and evaluation and other assets,
• Gains (losses) on sale of assets,
• Unrealized foreign exchange gains (losses),
• Share-based (expense) and other share-based compensation,
• Unrealized foreign exchange gains (losses) related to revaluation of deferred income tax asset and liability on non-monetary items,
• Non-recurring provisions,
• Non-recurring adjustments from unusual events or circumstances are reviewed from time to time based on materiality and the nature of the event or circumstance.

Management uses these measures for internal valuation of the cash flow generation ability of the period and to assist with planning and forecasting of future operations. Management believes that the presentation of EBITDA and Adjusted EBITDA provide useful information to investors because they exclude non-recurring items, items not related to or not indicative of current or future periods’ results and/or not directly related to the core mining business and are a better indication of the Company’s cash flow from operations as evaluated by internal management and the board of directors. The items excluded from the computation of Adjusted EBITDA, which are otherwise included in the determination of Net Earnings (Loss) prepared in accordance with IFRS, are items that the Company does not consider to be meaningful in evaluating the Company’s past financial performance or the future prospects and may hinder a comparison of its period-to-period performance comparisons.

The most directly comparable IFRS measure is Net Earnings (Loss). As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

CAUTIONARY NOTE TO U.S. INVESTORS REGARDING MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ in certain material respects from the disclosure requirements promulgated by the Securities and Exchange Commission (the “SEC”). For example, the terms “mineral reserve”, “proven mineral reserve”, “probable mineral reserve”, “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are Canadian mining terms as defined in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). These definitions differ from the definitions in the disclosure requirements promulgated by SEC. Accordingly, information contained in this press release may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.

NOTES ON MINERAL RESERVES AND MINERAL RESOURCES

Mineral Resources are stated effective as at December 31, 2025, reported at a 0.5 g/t cut-off grade, constrained within an $1,800/ounce pit shell and estimated in accordance with the 2014 CIM Standards and 43-101. Where Mineral Resources are stated alongside Mineral Reserves, those Mineral Resources are inclusive of, and not in addition to, the stated Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Mineral Reserves are stated effective as at December 31, 2025 and estimated in accordance with CIM Standards and NI 43-101. The Mineral Reserves:

• are inclusive of the Mineral Resources which were converted in line with the material classifications based on the level of confidence within the Mineral Resource estimate;
• reflect that portion of the Mineral Resources which can be economically extracted by open pit methods;
• consider the modifying factors and other parameters, including but not limited to the mining, metallurgical, social, environmental, statutory and financial aspects of the project;
• include an allowance for mining dilution and ore loss.

Mineral Reserve and Mineral Resource estimates are shown on a 100% basis. Designated government entities and national minority shareholders hold the following interests in each of the mines: 20% of Sadiola, 35% of Korali-Sud, 10.1% of Bonikro and 15% of Agbaou. Only a portion of the government interests are carried. The Government of Ethiopia is entitled to a 7% equity participation in Kurmuk once the mine enters into commercial production and certain governmental commitments such as public road upgrades and installation of a power line are complete.

The Mineral Resource and Mineral Reserve estimates for each of the Company’s mineral properties have been approved by the qualified persons within the meaning of NI 43-101 as set forth below:
