TORONTO, Feb. 19, 2026 (GLOBE NEWSWIRE) -- Centerra Gold Inc. (“Centerra” or the “Company”) (TSX: CG and NYSE: CGAU) today reported its fourth quarter and full year 2025 operating and financial results and issued 2026 guidance.

President and CEO, Paul Tomory, commented, “In the fourth quarter, we delivered strong production and outperformed our cost guidance, reflecting solid operational execution at Mount Milligan and Öksüt. During the quarter, both operations generated robust cash flow from operations, supporting strong free cash flow and reinforcing the quality of our portfolio. We ended the year with a cash balance of $529 million and an equity investment portfolio valued at over $115 million. This demonstrates our disciplined capital allocation strategy and highlights our ability to continue investing in the Thompson Creek restart project and our broader organic growth pipeline, including Mount Milligan, Kemess and Goldfield, while returning record capital to shareholders including $30 million in share buybacks in the fourth quarter and a consistent quarterly dividend of $10 million.”

“Looking ahead to 2026, our production and cost guidance reflect stable operating performance across our portfolio. We are committed to protecting and expanding margins through disciplined cost management and continuous operational initiatives at Mount Milligan. We expect our operations to continue generating strong cash flow in 2026, providing the financial flexibility to advance our growth project pipeline while returning capital to shareholders.”

Paul Tomory continued, “We are executing our self-funded growth strategy across multiple fronts. In January, we published results of the Kemess Preliminary Economic Assessment, highlighting the long-term potential of the project and further strengthening our growth pipeline by providing additional opportunities in British Columbia for future gold exposure. With Mount Milligan, Kemess, Goldfield and the Thompson Creek restart project, we have a clear line of sight to value-accretive, lower-risk growth that can be funded from available liquidity and future cash flows from operations, allowing us to maintain our disciplined approach to capital allocation.”

This includes $85.0 million of cash provided by mine operations and $53.6 million of free cash flow^NG at Mount Milligan and $57.1 million of cash provided by mine operations and $43.9 million of free cash flow^NG at Öksüt. This was partially offset by capital expenditures^NG at Thompson Creek. Full year 2025 cash provided by operating activities was $348.6 million and free cash flow^NG was $95.0 million. This includes $245.7 million of cash provided by mine operations and $168.4 million of free cash flow^NG at Mount Milligan and $229.3 million of cash provided by mine operations and $191.0 million of free cash flow^NG at Öksüt. This is partially offset by a free cash flow deficit^NG of $136.3 million from Thompson Creek expenditures.
• Cash and cash equivalents: As at December 31, 2025, total liquidity was $928.9 million, comprised of a cash balance of $528.9 million and $400.0 million available under an undrawn corporate credit facility.
• Returning capital to shareholders: Under Centerra’s normal course issuer bid (“NCIB”) program, the Company repurchased 2,297,900 common shares (“Shares”) in the fourth quarter 2025, for total consideration of $29.7 million. In the full year 2025, Centerra repurchased 11,493,316 Shares for total consideration of $93.7 million, representing approximately 5% of outstanding shares. Centerra has repurchased 23,884,446 shares since the inception of the buyback program. Centerra believes that the NCIB provides the Company with flexibility to strategically deploy cash in line with its capital allocation priorities, subject to market conditions, while maintaining the financial capacity to invest in future growth. A quarterly dividend of C$0.07 per common share was declared for a total of $10.0 million in the fourth quarter, and $41.1 million in the full year of 2025.
• Renewal of NCIB: In November 2025, Centerra renewed its NCIB to purchase for cancellation up to 20,129,230 Shares.
  

Strategic Growth Initiatives

• Kemess Preliminary Economic Assessment (“PEA”) demonstrates the potential to become Centerra’s second long-life gold-copper asset in British Columbia: In January 2026, Centerra published an updated mineral resource and the results of a PEA for the Kemess project (“Kemess”) in British Columbia, showing robust economics including an after-tax net present value (5%) (“NPV_5%”) of $1.1 billion and an after-tax internal rate of return (“IRR”) of 16%, using long-term pricing of $3,000 per ounce of gold and $4.50 per pound of copper. At commodity prices of approximately $4,500 per ounce of gold and $6.00 per pound of copper, the after-tax NPV_5% increases to $2.8 billion and the IRR increases to 29%. Kemess has the potential scale and jurisdictional advantages to complement Mount Milligan as a cornerstone asset. Importantly, Kemess is unencumbered by a gold or copper stream, positioning the project to deliver stronger economics and greater value creation for Centerra. For additional details, refer to the news release published on January 19, 2026 titled “Centerra Gold’s Kemess Preliminary Economic Assessment Highlights Strong Economics that Support the Company’s Long-Term Growth Pipeline”.
• Mount Milligan Life of Mine (“LOM”) extension to 2045: In September 2025, Centerra published the Pre-Feasibility Study (“PFS”) results for Mount Milligan which extends the LOM by approximately 10 years to 2045. The study outlines a disciplined, fully funded growth capital plan of approximately $186 million, most of which is not required until the early-to-mid-2030s. This includes the construction of a second TSF, process plant upgrades and additional flotation cells to increase throughput by about 10% to 66,300 tonnes per day (“tpd”) and increase recovery by approximately 1%, and five new haul trucks to support longer haul distances, higher material movement, and stockpile development. The PFS reaffirms Mount Milligan’s strong economics, with an after-tax NPV_5% of approximately $1.5 billion at long-term gold and copper price assumptions of $2,600 per ounce and $4.30 per pound, respectively, increasing to approximately $3.6 billion at spot commodity prices of $4,500 per ounce gold and $6.00 per pound copper, confirming its position as a cornerstone asset with a long mine life, attractive cost structure, and continued exploration potential in a leading mining jurisdiction. For additional details, refer to the news release published on September 11, 2025 titled “Centerra Gold’s Mount Milligan PFS Outlines Mine Life to 2045, Delivering Growth with a Fully Funded, Disciplined $186 Million Growth Capital Plan”. On October 21, 2025, the technical report was filed in relation to Mount Milligan.
• Advancing the Goldfield project: In August 2025, Centerra completed a technical study of its Goldfield project (“Goldfield”), showing robust project economics with an after-tax NPV_5% of $245 million and an after-tax IRR of 30%, based on a long-term gold price of $2,500 per ounce, which increases to $794 million at spot gold prices of $4,500 per ounce. Goldfield’s initial capital cost is estimated at $252 million, including approximately $40 million in pre-production stripping and other costs. Goldfield is expected to deliver a streamlined, low-risk development path, with first production targeted by the end of 2028. For additional details on Goldfield, refer to the news release published on August 6, 2025 titled “Centerra Gold Announces Attractive Economics on the Goldfield Project; Proceeding with Project Development and Construction Activities”.
  

Events Subsequent to Quarter End

• Mount Milligan received permit amendments to continue operations through 2035: On January 20, 2026, Centerra received an amended environmental assessment and all related permits to allow for the continuation of Mount Milligan’s operations through 2035. These authorizations include a 10% expansion in plant throughput beginning in 2028 and increased stockpile capacity needed for plant feed flexibility. In January 2025, Mount Milligan was selected by the Province of British Columbia as one of four mining projects which would qualify for expedited permitting to support economic development in the province. The receipt of these permit amendments, less than one year from being submitted, met the expedited schedule as per the province’s commitment.
• Full operations are expected to resume at Langeloth by May 2026 following a temporary suspension: On January 29, 2026, Centerra suspended operations at its Langeloth Metallurgical Facility (“Langeloth”) near Pittsburgh, Pennsylvania following an explosion adjacent to the acid plant. No fatalities, serious injuries or significant environmental releases were reported. The safety and well-being of employees, contractors and the surrounding community remain Centerra’s top priority. The Company is conducting a thorough investigation to determine the root cause of the incident, and that process remains ongoing. Operations at Langeloth remain temporarily suspended. The site team is co-operating with regulatory authorities, advancing repair activities and planning for a safe restart, with full operations expected to resume by May 2026. The impact was contained to an area of the site near the acid plant. Repairs are expected to cost approximately $5 to $10 million. As a result of the temporary suspension, working capital is expected to increase in the first quarter of 2026 as inventories build during the shutdown period. The Company continues to assess the full operational and financial impacts of this incident and will provide 2026 operating guidance for Langeloth at a later date.

2026 Guidance Highlights

• Production: In 2026, consolidated gold production is expected to be 250,000 to 280,000 ounces. Copper production in 2026 is expected to be 50 to 60 million pounds. The guidance ranges are focused on executing against the PFS mine plan at Mount Milligan and consistent operational performance at Öksüt.
• Costs: In 2026, consolidated gold production costs are expected to be $1,500 to $1,600 per ounce and AISC on a by-product basis^NG is expected to be $1,650 to $1,750 per ounce.
• Capital Expenditures^NG: In 2026, sustaining capital expenditures^NG are expected to be $85 to $105 million, and non-sustaining capital expenditures^NG are expected to be $260 to $315 million. Non-sustaining capital expenditures^NG are mainly driven by the Thompson Creek restart project, launching long-lead procurement and initiating site establishment works at Goldfield, and haul truck additions and buttress foundation construction at Mount Milligan.
• Molybdenum Roasting: Following the incident that occurred at Langeloth in late January 2026, Centerra continues to assess the full operational and financial impacts, and will provide 2026 operating guidance for Langeloth at a later date.

Mount Milligan

Mount Milligan produced 44,105 ounces of gold and 13.0 million pounds of copper in the fourth quarter of 2025. In the full year 2025, Mount Milligan produced 147,581 ounces of gold and 50.5 million pounds of copper, which was in line with the recently announced PFS mine plan. During the fourth quarter of 2025, a total of 11.1 million tonnes were mined from phases 5, 6, 7 and 10 of the open pit. Process plant throughput for the fourth quarter of 2025 was 5.3 million tonnes, averaging 57,977 tonnes per day. Gold sales were 38,264 ounces and copper sales were 12.5 million pounds in the fourth quarter. Gold and copper sales were lower than production in the quarter as a result of weather-related disruptions to logistics in late December, with the timing difference in sales expected to reverse in 2026.

In 2026, gold production at Mount Milligan is expected to be 140,000 to 155,000 ounces and copper production is expected to be 50 to 60 million pounds. Operating metrics, including gold and copper grades and recoveries, are expected to be in line with the recently announced PFS mine plan. Gold production and sales are expected to be higher in the second and third quarters of 2026, reflecting planned mine sequencing, with approximately 20% of full-year gold production expected in the first quarter of 2026. Copper production and sales are expected to be evenly weighted throughout 2026.

Gold production costs in the fourth quarter 2025 were $1,306 per ounce. AISC on a by-product basis^NG was $913 per ounce, 38% lower than the third quarter of 2025 due to higher ounces produced and sold during the quarter. In 2025, full year gold production costs and AISC on a by-product basis^NG at Mount Milligan were $1,388 per ounce and $1,194 per ounce, respectively, outperforming the guidance ranges. Gold production costs in 2026 at Mount Milligan are expected to be $1,450 to $1,550 per ounce and AISC on a by-product basis^NG is expected to be $1,200 to $1,300 per ounce, similar to 2025 levels.

Sustaining capital expenditures^NG at Mount Milligan in the fourth quarter of 2025 were $20.1 million, focused on the existing TSF dam construction. In 2026, Mount Milligan additions to PP&E are expected to be $115 to $135 million, comprising $80 to $90 in sustaining capital expenditures^NG and $35 to $45 million in non-sustaining capital^NG. Sustaining capital^NG includes annual capital related to the existing TSF, water management projects to sustain access to water, and mine fleet equipment replacements. Non-sustaining capital^NG includes haul truck additions and buttress foundation construction.

In the fourth quarter of 2025, Mount Milligan generated $85.0 million of cash flow from mine operations and free cash flow^NG of $53.6 million. Full year cash flow from mine operations and free cash flow^NG were $245.7 million and $168.4 million, respectively.

In September 2025, Centerra announced the results of a PFS for Mount Milligan which extends the LOM by approximately 10 years to 2045, supported by an optimized mine plan delivering average annual production of 150,000 ounces of gold and 69 million pounds of copper from 2026 to 2042, followed by the processing of low-grade stockpiles from 2043 to 2045. The study outlines disciplined non-sustaining capital expenditures^NG of approximately $186 million, most of which are not required until the early-to-mid-2030s, all fully funded from available liquidity and future cash flow from operations. Key investments include $114 million for a second TSF, to be spent across 2032 and 2033, which also provides the potential for future raises, adding multiple decades of storage capacity beyond the 2045 LOM, $36 million for ball mill motor upgrades and flotation cells in 2028 to increase process plant throughput by about 10% to 66,300 tpd and increase recovery by approximately 1%, and $28 million for five new haul trucks to support longer haul distances, higher material movement, and stockpile development. Proven and probable reserves announced in the PFS increased significantly to 4.4 million ounces of gold and 1.7 billion pounds of copper, representing a 56% and 52% increase, respectively, from year-end 2024. Recent drilling confirms mineralization remains open to the west of the current resource pit. Centerra continues to advance exploration aimed at expanding the mineral resource and assessing opportunities to extend the mine life beyond the updated plan.

The PFS reaffirms Mount Milligan’s strong economics, with an after-tax NPV_5% of approximately $1.5 billion at long-term gold and copper price assumptions of $2,600 per ounce and $4.30 per pound, respectively, increasing to approximately $3.6 billion at spot commodity prices of $4,500 per ounce gold and $6.00 per pound copper. Mount Milligan remains a strategic cornerstone asset in Centerra’s portfolio, with 20 years of mine life, meaningful gold and copper production, strong cash flow generation, and significant opportunity for future exploration potential in a top tier mining jurisdiction. For additional details, refer to the news release published on September 11, 2025 titled “Centerra Gold’s Mount Milligan PFS Outlines Mine Life to 2045, Delivering Growth with a Fully Funded, Disciplined $186 Million Growth Capital Plan”.

Öksüt

Öksüt produced 26,748 ounces of gold in the fourth quarter of 2025. Full year production in 2025 was 127,734 ounces, which exceeded the top end of the guidance range. During the quarter, mining activities were focused on phase 5 and phase 6 of the Keltepe pit and in phase 2 of the Güneytepe pit. A total of 5.3 million tonnes of ore and waste were mined in the quarter and 0.4 million tonnes were stacked at an average grade of 1.95 g/t. As part of planned mine sequencing in the fourth quarter 2025, heap leach tonnes stacked were lower as mining activity focused on waste stripping in the Keltepe pit to open new ore zones in line with the 2026 mine plan.

In 2026, gold production is expected to be 110,000 to 125,000 ounces, slightly below 2025 levels due to lower grades related to mine sequencing. Gold production and sales are expected to be evenly weighted throughout 2026.

At Öksüt, gold production costs and AISC on a by-product basis^NG for the fourth quarter 2025 were $1,199 per ounce and $1,748 per ounce, respectively. AISC on a by-product basis^NG was higher compared to last quarter driven by lower gold ounces sold, higher sustaining capital expenditures^NG, and higher royalty expense per ounce due to elevated gold prices. Full year gold production costs were $1,199 per ounce and AISC on a by-product basis^NG was $1,613 per ounce, coming in below the guidance ranges.

2026 gold production costs at Öksüt are expected to be $1,650 to $1,750 per ounce, and AISC on a by-product basis^NG is expected to be $1,850 to $1,950 per ounce, both higher year-over-year primarily due to increased royalty rates due to elevated gold prices and the impact of inflation in Türkiye, which is not fully offset by devaluation of the lira. The royalty is expected to account for approximately $650 to $750 per ounce of gold production costs in 2026. The impact of these factors on AISC on a by-product basis^NG is partially offset by lower sustaining capital expenditures.

In the fourth quarter 2025, sustaining capital expenditures at Öksüt were $13.2 million, focused on capitalized stripping and heap leach pad expansion. Full year 2025 sustaining capital expenditures^NG were $38.3 million, in line with the guidance range. In 2026, Öksüt additions to PP&E are expected to be $5 to $15 million, all of which is sustaining capital^NG, lower year-over-year as there is no planned capitalized stripping in 2026 and most of the sustaining capital^NG projects are now complete.

In the fourth quarter of 2025, Öksüt delivered cash flow from mine operations of $57.1 million and free cash flow^NG of $43.9 million. In the full year 2025, Öksüt generated $229.3 million of cash flow from mine operations and $191.0 million of free cash flow^NG.

The Turkish corporate income tax rate applicable to Öksüt is 25%. In 2026, Öksüt’s current income taxes paid are expected to be $105 to $125 million, which includes a withholding tax related to the repatriation of earnings. Cash flows at Öksüt in the second quarter of 2026 are expected to be impacted by the expected timing of tax and annual royalty payments.

Centerra has initiated a Life of Mine Optimization study at Öksüt to evaluate the asset’s full potential, including the incremental production potential of residual leaching of the heap leach facility and the inclusion of low-grade oxide mineralization, outside of the current reserve pit, into the mine plan. The study will explore options to extend gold recovery from existing leach pads through improved solution management, which will enhance residual metal extraction efficiency. The study is expected to be completed by the end of 2026 and will support updates to the mine’s long-term reclamation and site management plan, ensuring the operation continues to maximize metal recovery in a safe and responsible manner.

Molybdenum Business Unit (“MBU”)

The MBU used $14.9 million of cash in operations and recorded a free cash flow deficit^NG of $61.0 million, in the fourth quarter of 2025, reflecting capital spending on the restart of Thompson Creek and working capital increases at Langeloth due to an increase in inventory on hand.

Thompson Creek Mine

The restart of Thompson Creek is advancing, with approximately 27% of the infrastructure refurbishment complete. In the fourth quarter of 2025, non-sustaining capital expenditures^NG were $50.5 million and full year 2025 non-sustaining capital expenditures^NG were within the guidance range, totalling $135.6 million. Since the restart decision in September 2024, non-sustaining capital expenditures^NG have totaled $163.8 million.

Centerra has increased the project’s total capital estimate by approximately 5% to 10%, from $397 million to between $425 and $450 million, reflecting modest inflationary impacts as the Feasibility Study was based on 2024 costs, additional maintenance requirements for certain mining equipment, and refinements to the mine plan. The updated estimate also includes the pull-forward of select activities, including the tailings dam toe buttress, to further de-risk execution and support the overall project schedule. The project remains on track for first production in mid-2027.

In 2026, additions to PP&E at Thompson Creek are expected to be $205 to $235 million, inclusive of capitalized DDA, and non-sustaining capital expenditures^NG are expected to be $190 to $220 million, focused on mill refurbishment, capitalized stripping, and tailings and water management infrastructure.

Langeloth

In the fourth quarter of 2025, Langeloth roasted and sold 3.6 million pounds and 3.6 million pounds of molybdenum, respectively. In the fourth quarter, Langeloth delivered a positive adjusted EBITDA^NG of $4.9 million and used $12.1 million of cash flow from operations, primarily related to an increase in inventories as part of the planned ramp-up of production. In the full year 2025, Langeloth roasted and sold 14.2 million and 14.0 million pounds, respectively. Langeloth delivered a positive adjusted EBITDA^NG of $6.3 million and used $27.3 million of cash flow from operations.

On January 29, 2026, Centerra suspended operations at Langeloth near Pittsburgh, Pennsylvania following an explosion adjacent to the acid plant. No fatalities, serious injuries or significant environmental releases were reported. The safety and well-being of employees, contractors and the surrounding community remain Centerra’s top priority. The Company is conducting a thorough investigation to determine the root cause of the incident, and that process remains ongoing. Operations at Langeloth remain temporarily suspended. The site team is co-operating with regulatory authorities, advancing repair activities and planning for a safe restart, with full operations expected to resume by May 2026. The impact was contained to an area of the site near the acid plant. Repairs are expected to cost approximately $5 to $10 million. As a result of the temporary suspension, working capital is expected to increase in the first quarter of 2026 as inventories build during the shutdown period. The Company continues to assess the full operational and financial impacts and will provide 2026 operating guidance for Langeloth at a later date.

Goldfield Project

In August 2025, Centerra completed a technical study of Goldfield, confirming robust project economics with an after-tax NPV_5% of $245 million and an after-tax IRR of 30%, based on a long-term gold price of $2,500 per ounce. At spot gold prices of $4,500 per ounce, the NPV_5% increases to $794 million. The Project’s initial capital cost is estimated at $252 million, including approximately $40 million in pre-production stripping and other costs. Goldfield is expected to deliver a streamlined, low-risk development path, with first production targeted by the end of 2028. Recent optimization work and technical enhancements, together with strong gold prices, have further improved project value and reduced risk, positioning Goldfield as a key near-term growth opportunity for Centerra. For additional details on Goldfield, refer to the news release published on August 6, 2025 titled “Centerra Gold Announces Attractive Economics on the Goldfield Project; Proceeding with Project Development and Construction Activities”.

In the fourth quarter of 2025, Centerra advanced Goldfield development activities, with engineering progressing as planned and early mobilization efforts progressing on site, and field campaigns completed to support the advancement of detailed engineering. The Company is building out a dedicated project team to ensure the required technical and operational expertise is in place. In January 2026, Centerra hired Michael Rowland as General Manager, Goldfield, who brings over 25 years of mining leadership experience across operations, maintenance and processing. These early actions mark important steps toward project readiness and position Goldfield for disciplined and efficient delivery.

In 2026, non-sustaining capital expenditures^NG at Goldfield are expected to be $30 to $40 million, focused on finalizing engineering studies, launching long-lead procurement and initiating site establishment works.

Kemess Project

In January 2026, Centerra published an updated mineral resource and the results of a PEA for the Kemess project in British Columbia, showing robust economics including an after-tax NPV_5% of $1.1 billion and an after-tax IRR of 16%, using long-term pricing of $3,000 per ounce of gold and $4.50 per pound of copper. The PEA mineral inventory of over 2.3 million ounces of contained gold and 851 million pounds of contained copper represents approximately 47% of the total indicated and inferred resource tonnes, providing Kemess with strong leverage to rising metal prices, with further upside potential as ongoing exploration advances resource growth and confidence. At commodity prices of approximately $4,500 per ounce of gold and $6.00 per pound of copper, the after-tax NPV_5% increases to $2.8 billion and the IRR increases to 29%. The Kemess PEA outlines a development approach in which open pit mining begins first, followed by the start of underground production approximately two years later. This approach supports strong economics, including an initial 15-year mine life with average annual production of 171,000 ounces of gold and 61 million pounds of copper, at an AISC on a by-product basis^NG of $971 per ounce. Kemess has the scale and jurisdictional advantages to complement Mount Milligan as a cornerstone asset. Importantly, Kemess is unencumbered by a gold or copper stream, positioning the project to deliver stronger economics and greater value creation for Centerra. For additional details, refer to the news release published on January 19, 2026 titled “Centerra Gold’s Kemess Preliminary Economic Assessment Highlights Strong Economics that Support the Company’s Long-Term Growth Pipeline”.

Non-sustaining capital expenditures^NG in 2026 are expected to be $5 to $10 million, primarily related to early works for the water treatment plant and camp infrastructure in support of future development. Other expenditures in 2026 include $13 to $15 million on care and maintenance, $5 to $7 million on exploration drilling, and $17 to $23 million on technical studies related to the PFS expected in 2027.

Global Exploration

In 2026, exploration expenditures are expected to be $40 to $50 million, including $20 to $25 million of brownfield exploration and $20 to $25 million of greenfield and generative exploration programs. Over 90% of exploration expenditures are expected to be expensed. The exploration targets for brownfield projects include continued drilling and testing work at Mount Milligan and Kemess.

2026 Material Assumptions

Material assumptions or factors used to forecast production and costs for 2026, after giving effect to the hedges in place as at December 31, 2025, include the following:

• A market gold price of $4,500 per ounce and an average realized gold price at Mount Milligan of $3,077 per ounce after reflecting the Mount Milligan Streaming Agreement (35% of Mount Milligan’s gold at $435 per ounce) and gold refining costs.
• A market copper price of $5.00 per pound and an average realized copper price at Mount Milligan of $4.20 per pound after reflecting the Mount Milligan Streaming Agreement (18.75% of Mount Milligan’s copper at 15% of the spot price per metric tonne) and copper treatment and refining costs.
  
• Exchange rates: $1USD:$1.38 Canadian dollar; $1USD:45.00 Turkish lira.
• Diesel fuel price assumption: $0.90 per litre (C$1.24 per litre) at Mount Milligan and $2.70 per US gallon at Thompson Creek.
  

Other Material Assumptions

Other material assumptions used in forecasting production and costs for 2026 can be found under the heading “Caution Regarding Forward-Looking Information” in this document. Production, cost, and capital forecasts for 2025 are forward-looking information and are based on key assumptions and subject to material risk factors that could cause actual results to differ materially and which are discussed under the heading “Risk Factors” in the Company’s most recent Annual Information Form.

2026 Sensitivities

Centerra’s revenues, earnings and cash flows for 2026 are sensitive to changes in certain key inputs or currencies. The Company has estimated the impact of any such changes in the table below.

⁽¹⁾ Includes the impact of hedging of 20,000 ounces for the Öksüt Mine’s gold sales in 2026. Excludes the effect of 35,004 ounces of gold with an average mark-to-market price of $4,338 per ounce and 11.5 million pounds of copper with an average mark-to-market price of $5.64 per pound outstanding under the Mount Milligan Mine’s contracts awaiting final settlement in future months as of December 31, 2025.

⁽²⁾ Includes the effect of the Company’s diesel fuel and Canadian dollar hedging programs, with current exposure coverage as of December 31, 2025 of approximately 47% and 59%, respectively.

⁽³⁾ Appreciation of the currency against the US dollar results in higher costs and lower cash flow and earnings. Depreciation of the currency against the US dollar results in decreased costs and increased cash flow and earnings.

Non-GAAP and Other Financial Measures

This document contains “specified financial measures” within the meaning of NI 52-112, specifically the non-GAAP financial measures, non-GAAP ratios and supplementary financial measures described below. Management believes that the use of these measures assists analysts, investors and other stakeholders of the Company in understanding the costs associated with producing gold and copper, understanding the economics of gold and copper mining, assessing operating performance, the Company’s ability to generate free cash flow from current operations and on an overall Company basis, and for planning and forecasting of future periods. However, the measures have limitations as analytical tools as they may be influenced by the point in the life cycle of a specific mine and the level of additional exploration or other expenditures a company has to make to fully develop its properties. The specified financial measures used in this document do not have any standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other issuers, even as compared to other issuers who may be applying the World Gold Council (“WGC”) guidelines. Accordingly, these specified financial measures should not be considered in isolation, or as a substitute for, analysis of the Company’s recognized measures presented in accordance with IFRS.

Definitions

The following is a description of the non-GAAP financial measures, non-GAAP ratios and supplementary financial measures used in this document:

• All-in sustaining costs on a by-product basis per ounce is a non-GAAP ratio calculated as all-in sustaining costs on a by-product basis divided by ounces of gold sold. All-in sustaining costs on a by-product basis is a non-GAAP financial measure calculated as the aggregate of production costs as recorded in the consolidated statements of earnings, refining and transport costs, the cash component of capitalized stripping and sustaining capital expenditures, lease payments related to sustaining assets, corporate general and administrative expenses, accretion expenses, asset retirement depletion expenses, copper and silver revenue and the associated impact of hedges of by-product sales revenue. When calculating all-in sustaining costs on a by-product basis, all revenue received from the sale of copper from the Mount Milligan Mine, as reduced by the effect of the copper stream, is treated as a reduction of costs incurred. A reconciliation of all-in sustaining costs on a by-product basis to the nearest IFRS measure is set out below. Management uses these measures to monitor the cost management effectiveness of each of its operating mines.
• All-in sustaining costs on a co-product basis per ounce of gold or per pound of copper, is a non-GAAP ratio calculated as all-in sustaining costs on a co-product basis divided by ounces of gold or pounds of copper sold, as applicable. All-in sustaining costs on a co-product basis is a non-GAAP financial measure based on an allocation of production costs between copper and gold based on the conversion of copper production to equivalent ounces of gold. The Company uses a conversion ratio for calculating gold equivalent ounces for its copper sales calculated by multiplying the copper pounds sold by estimated average realized copper price and dividing the resulting figure by estimated average realized gold price. For the three and nine months ended December 31, 2025, 655 and 659 pounds of copper were equivalent to one ounce of gold. A reconciliation of all-in sustaining costs on a co-product basis to the nearest IFRS measure is set out below. Management uses these measures to monitor the cost management effectiveness of each of its operating mines.
• Sustaining capital expenditures and Non-sustaining capital expenditures are non-GAAP financial measures. Sustaining capital expenditures are defined as those expenditures required to sustain current operations and exclude all expenditures incurred at new operations or major projects at existing operations where these projects will materially benefit the operation. Non-sustaining capital expenditures are primarily costs incurred at ‘new operations’ and costs related to ‘major projects at existing operations’ where these projects will materially benefit the operation. A material benefit to an existing operation is considered to be at least a 10% increase in annual or life of mine production, net present value, or reserves compared to the remaining life of mine of the operation. A reconciliation of sustaining capital expenditures and non-sustaining capital expenditures to the nearest IFRS measures is set out below. Management uses the distinction of the sustaining and non-sustaining capital expenditures as an input into the calculation of all-in sustaining costs per ounce and all-in costs per ounce.
• Adjusted net earnings is a non-GAAP financial measure calculated by adjusting net earnings as recorded in the consolidated statements of earnings for items not associated with ongoing operations. The Company believes that this generally accepted industry measure allows the evaluation of the results of income-generating capabilities and is useful in making comparisons between periods. This measure adjusts for the impact of items not associated with ongoing operations. A reconciliation of adjusted net earnings to the nearest IFRS measures is set out below. Management uses this measure to monitor and plan for the operating performance of the Company in conjunction with other data prepared in accordance with IFRS.
• Adjusted EBITDA is a non-GAAP financial measure calculated by adjusting net earnings as recorded in the consolidated statements of earnings by depreciation, amortization, interest, taxes and items not associated with ongoing operations. The Company believes that this generally accepted industry measure allows the evaluation of the results of income-generating capabilities and is useful in making comparisons between periods. A reconciliation of adjusted EBITDA to the nearest IFRS measures is set out below. Management uses this measure to monitor and plan for the operating performance of the Company in conjunction with other data prepared in accordance with IFRS.
• Free cash flow (deficit) is a non-GAAP financial measure calculated as cash provided by operating activities less property, plant and equipment additions. A reconciliation of free cash flow to the nearest IFRS measures is set out below. Management uses this measure to monitor the amount of cash available to reinvest in the Company and allocate for shareholder returns.
• Mining costs per tonne mined is a non-GAAP financial measure calculated by dividing the mining costs by the number of tonnes mined. Management uses these measures to monitor the cost management effectiveness of the mining process for each of its operating mines.
• Processing costs per tonne stacked is a non-GAAP financial measure calculated by dividing the processing costs by the number of tonnes milled or stacked. Management uses these measures to monitor the cost management effectiveness of the mine processing for each of its operating mines.
• Site G&A costs per tonne processed is a non-GAAP financial measure calculated by dividing the site G&A costs by the number of tonnes milled or stacked. Management uses these measures to monitor the cost management effectiveness of the site G&A process for each of its operating mines.
• On site costs per tonne processed is a non-GAAP financial measure calculated by dividing the operating expenses less changes in inventories, royalties and other costs by the number of tonnes milled or stacked. Management uses these measures to monitor the cost management effectiveness of the relevant production costs for each of its operating mines.
