Use of Non-GAAP and Other Specified Financial Measures 3 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 MD&A 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. 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 condensed consolidated statements of (loss) 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. • 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 (loss) is a non-GAAP financial measure calculated by adjusting net (loss) earnings as recorded in the condensed consolidated statements of (loss) 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 (loss) 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. • Free cash flow (deficit) is a non-GAAP financial measure calculated as cash provided by operating activities from continuing operations 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. • Average realized gold price is a supplementary financial measure calculated by dividing the different components of gold sales (including third party sales, mark-to-market adjustments, final pricing adjustments and the fixed amount received under the Mount Milligan Mine Streaming Agreement) by the number of ounces sold. Management uses this measure to monitor its sales of gold ounces against the average market gold price. • Average realized copper price is a supplementary financial measure calculated by dividing the different components of copper sales (including third party sales, mark-to-market adjustments, final pricing adjustments and the fixed amount received under the Mount Milligan Mine Streaming Agreement) by the number of pounds sold. Management uses this measure to monitor its sales of gold ounces against the average market copper price. • Total liquidity is a supplementary financial measure calculated as cash and cash equivalents and amount available under the corporate credit facility. Credit facility availability is reduced by outstanding letters of credit. Management uses this measure to determine if the Company can meet all of its commitments, execute on the business plan, and to mitigate the risk of economic downturns. • Adjusted EBITDA is a non-GAAP financial measure that represents earnings before interest, taxes, depreciation, and amortization. It is calculated by adjusting net earnings as recorded in the consolidated statements of earnings by depreciation and amortization. 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. Additional information about these measures, including explanations of their composition, explanations of how these measures provide useful information to investors and quantitative reconciliations to the most directly comparable financial measures in the Company’s unaudited financial statements for the quarters ended June 30, 2026 and 2025, is included in the section titled “Non-GAAP and Other Financial Measures” of the Q2 2026 MD&A, which section is incorporated by reference herein. The Q2 2026 MD&A is available under the Company’s profile on SEDAR+ at www.sedarplus.ca.

20 2026 Exploration at Mount Milligan Exploration drilling program aimed at expanding the mineral resource base MOUNT MILLIGAN EXPLORATION PROGRAM Centerra plans to invest $8 – $11 million in exploration at Mount Milligan in 2026. 20% of Centerra’s total 2026 exploration expenditures have been allocated to drilling programs at Mount Milligan to upgrade the inferred resources between Goldmark and North Slope and to expand the resources at Saddle West and South Boundary areas. Previous drilling and modelling of the South Boundary area identified high-grade gold, low copper vein mineralization confirming that the zone represents a gold rich cap of an underlying porphyry deposit. Continued drilling within the area has the potential to identify a gold- copper mineralization northwest towards the Boundary zone area. In 2026, Centerra is expected to continue to explore the western extension of the Mount Milligan deposit and perform infill drilling to upgrade the inferred resources to the indicated category. Ongoing exploration continues to highlight the potential to further expand mineral resources and extend mine life beyond the updated 2025 PFS mine plan. 2026 Planned Drill Holes

26 An isometric view of the open pit and underground concept The Kemess PEA utilizes an integrated open pit and underground mining strategy, with ore from Kemess Main being conveyed to the infrastructure at Kemess South Kemess Operating Strategy KEMESS INTEGRATED MINING STRATEGY Streamlined project execution through integrated open pit and underground mining strategy: The Kemess PEA outlines a development approach in which open pit mining begins first, followed by the start of long-hole open stoping underground development and production. Approximately 2 years after the start of the open pit. Once underground production starts, both mining methods operate concurrently for the remainder of the projected 15-year mine life. The integrated mine plan helps streamline project execution, optimize plant feed, and utilize existing infrastructure, while maintaining the expected timeline to first production in late 2031. Permitting is well advanced, with some approvals in place from prior block cave project; amendments will be needed to align with the updated development plan.

Molybdenum: What Is It, How Is It Used? 41 Molybdenum (Mo) is mainly a by-product of copper mining, with primary molybdenum mines like Centerra’s Thompson Creek mine yielding high-grade concentrate Concentrates are blended to meet metallurgical or chemical grade specifications and roasted Can be further processed into value-added products like briquettes, ferromolybdenum, and pure molybdenum oxide that command a higher premium Around 672 million pounds of new molybdenum was used in 2025, with the most used in engineered steels (38%) and stainless steels (26%)(1) Technical Oxide Ferromolybdenum Chemical Grade Specialty Products Similar steel performance benefits to technical oxide Has a premium and higher contribution margin than technical oxide Can be used for any molybdenum-containing steel; preferred due to lower losses in steelmaking, even when accounting for premium pricing Used in catalysts, lubricants, pigments, corrosion inhibitors, etc. Has rigorous and high-purity specification requirements Supplied largely by concentrates from primary molybdenum mines due to requirements for high purity In general, chemical grade products command a premium and have a higher contribution margin Used in the production of engineered and stainless steels Currently the most common form of molybdenum, used in steel making Adds strength properties to steel; corrosion resistant; used in high-performance applications Metallurgical Grade (1) International Molybdenum Association, IMOA Latest news; Molybdenum Market Information.

43 Molybdenum Supply: Potential Challenges Ahead Thompson Creek is one of three primary molybdenum mines in the world, outside of China High-quality molybdenum concentrate is scarce, creating a unique opportunity for Thompson Creek Molybdenum supply is principally produced as a by-product from certain copper mines Molybdenum by-product production from existing copper mines, particularly in South America, has decreased in part due to investment challenges Cost of bringing on such mines is significant, leading to delays and deferrals As a result, molybdenum supply has been constrained Only three primary (non-by-product) molybdenum mines outside of China Thompson Creek is expected to begin production in mid-2027 Thompson Creek has the lowest expected project development costs of new primary molybdenum supply ($425 - 450M versus more than $800M for other projects (2)) Brownfield restart at Thompson Creek de-risks capital investment Thompson Creek is a unique opportunity for Centerra to have a captive source of high-quality feed, which is becoming increasingly scarce and competitive to source (1) Third party commodity research reports. (2) The other projects include: Malmbjerg Molybdenum Project (owned by Greenland Resources), Kitsault Molybdenum Mine (owned by New Moly), Shapinggou Molybdenum Mine (majority-owned by Zijin Mining). Thompson Creek is forecasted to be one of the near-term primary molybdenum mines to start production(1)

Langeloth maintains profitability even at lower molybdenum prices. Mo market price regulated by LME Platts Working capital requirements fluctuate with the Mo market price due to purchases of third-party concentrate Price established through Quotational Period (1) (“QP”) mechanisms, which determine the month in which the price paid for concentrate purchases and price received for product sales is finalized Quotational period contract mechanism ILLUSTRATIVE January February March April Concentrate Purchases @ QP = M+2 Concentrate price finalization Sales price finalization Molybdenum product sale @ QP = M-1 Blending and Roasting at Langeloth (1) The “quotational period” (QP) is the period during which the metal prices are established for payment. QP is stipulated i n each contract; generally, it is defined as ‘calendar month prior to shipment’, ‘first month following delivery’, ‘second month following delivery’. QP may vary from calendar month prior, to shipment, to first or second calendar month following date of delivery. This impacts the timing at which payment is made as well as the price paid/received. Aligning supplier and customer QP allows to reduce market price exposure and risk of volatile market prices.

Mineral Reserves & Resources Additional Footnotes 58 General Conversion factors used in the mineral resource and reserve estimates: 31.1035 grams per troy ounce; 2204.62 lbs per metric tonne; 0.9072 metric tonnes per short ton. Unless otherwise noted, an exchange rate of 1USD:1.33CAD was used for estimating resources and reserves. Mount Milligan Mine The mineral reserves are reported based on a gold price of $1,800 per ounce, a copper price of $3.75 per pound. The open pit mineral reserves are reported based on a Net Smelter Return (“NSR”) cut-off of $8.45 per tonne (C$11.24 per tonne) that considers metallurgical recoveries, concentrate grades, transportation costs, and smelter treatment charges to determine economic viability. Reserves include 31.7 million tonnes of marginal material to be processed at the end of mine life for closure purposes. The mineral resources are reported based on a gold price of $2,400 per ounce, a copper price of $4.00 per pound. The open pit mineral resources are constrained by a pit shell and are reported based on a NSR cut-off of $8.45 per tonne (C$11.24 per tonne) that considers metallurgical recoveries, concentrate grades, transportation costs, and smelter treatment charges to determine economic viability. Further information concerning the Mount Milligan deposit, operation, as well as environmental and other risks is described in Centerra’s most recently filed Annual Information Form which is available on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.g ov/edgar and the Technical Report for the Mount Milligan PFS, with an effective date of June 30, 2025 (filed on October 17, 2025), which is available on SEDAR+ at www.sedarplus.ca. Öksüt Mine The mineral reserves are reported based on a gold price of $2,000 per ounce and an exchange rate of 1USD:42TL. The open pit mineral reserves are reported based on 0.20 grams of gold per tonne cut-off grade. Open pit optimization used an average life of mine (“LOM”) metallurgical recovery of 77%. The mineral resources are reported based on a gold price of $2,400 per ounce. Open pit mineral resources are constrained by a pit shell and are estimated based on a cut-off grade of 0.17 grams of gold per tonne. Further information concerning the Öksüt deposit, operation, as well as environmental and other risks is described in Centerra’s most recently filed Annual Information Form which is available on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar and the Technical Report on the Öksüt Project, dated September 3, 2015, which is available on SEDAR+ at www.sedarplus.ca. Kemess The mineral resources are reported based on a gold price of $2,400 per ounce, a copper price of $4.00 per pound, a silver price of $25.00 per ounce. The Kemess Main open pit mineral resources (including the Nugget zone) are constrained by a pit shell and are reported based on a Net Smelter Return (“NSR”) cut-off of $12.01 per tonne (C$15.97 per tonne) that considers materials handling costs, metallurgical recoveries, concentrate grades, transportation costs, and smelter treatment charges to determine economic viability. A dilution factor of 0% and a mining recovery of 100% is used. The Kemess South open pit mineral resources are constrained by a pit shell and are reported based on a NSR cut-off of $9.98 per tonne (C$13.27 per tonne) that considers metallurgical recoveries, concentrate grades, transportation costs, and smelter treatment charges to determine economic viability. A dilution factor of 0% and a mining recovery of 100% is used. The Kemess Underground mineral resource is constrained by optimized stope shapes using commercially available software and reported with a NSR stope cut-off value of $41.71 per tonne (C$55.47 per tonne), representing the value required to cover mining, processing, general and administrative, and appropriate sustaining capital costs. Economic screening was performed on stope shapes to ensure reasonable prospects for eventual economic extraction. Dilution was estimated using equivalent linear overbreak sloughing (“ELOS”) for each stope type and ore-waste contacts, which vary between zero and 1.25 metres. Mining recovery of 93% was applied to all stopes. The Kemess East underground mineral resource is constrained by optimized stope shapes using commercially available software and reported with a NSR stope cut-off value of $41.71 per tonne (C$55.47 per tonne), representing the value required to cover mining, processing, general and administrative, and appropriate sustaining capital costs. Economic screening was performed on stope shapes to ensure reasonable prospects for eventual economic extraction. Dilution was estimated using ELOS for each slope type and ore-waste contacts, which vary between zero and 1.25 metres. Mining recovery of 93% was applied to all stopes. The Kemess Main open pit shell was restricted to a minimum floor elevation of 1,355 metres above sea level (“masl”) and the Kemess Underground optimized stope shapes were restricted to a maximum elevation of 1,355 masl, to represent the conceptual transition between open pit and underground mining zones for resource estimation purposes. A portion of the mineral resource estimate is included in the economic analysis for the PEA, which is limited to the Kemess Main open pit and Kemess Underground zones. This is a conservative subset that reflects mining, processing and economic assumptions. It is important to note that the PEA mining inventory is not a mineral reserve and does not demonstrate economic viability. The subset of the mineral resource used in the PEA was based on a gold price of $2,000 per ounce, a copper price of $3.75 per pound, a silver price of $22.50 per ounce. Thompson Creek Mine The mineral reserves are reported on a molybdenum price of $16.00 per pound. The open pit mineral reserves are based on a 0.030% molybdenum cut-off grade. The mineral resources are reported on a molybdenum price of $18.50 per pound. The open pit mineral resources are constrained by a pit shell and are estimated based on a 0.025% molybdenum cut-off grade. Further information concerning the Thompson Creek deposit, current and planned operations as well as environmental and other risks are described in the technical report with an effective date of September 1, 2024 and filed on SEDAR+ at www.sedarplus.ca. Endako Mine The mineral resources are reported based on a molybdenum price of $14.00 per pound and an exchange rate of 1USD:1.25CAD. The open pit mineral resources are constrained by a pit shell and are estimated based on a 0.025% molybdenum cut-off grade.

Mineral Reserves & Resources Additional Footnotes 59 Goldfield The following formula was used to calculate cut-off grade for each mineralized zone: [Processing cost + G&A cost] / [Recovery * (Gold Price * Payability Factor * (1- Royalty%) – Selling Cost)] where G&A cost is $0.55/t, payability factor is 99.9% and selling cost is $5/oz. Goldfield Reserves Mineral reserves are reported in metric tonnes based on a gold price of $2,000/oz. Mineral reserve estimates are supported by mineable pit designs, detailed LOM plan, equipment simulations, capital and operating cost estimates, and financial analysis. Mining Cost: A base mining cost of $3.47/t was applied with an incremental haulage costs of $0.31/t and $0.35/t applied to Goldfield Main and McMahon Ridge respectively. A general and administrative (“G&A”) cost of $0.55/t was applied for constraining the pit shell. Pit Slope Angles: Overall slope angles were assumed to be 35 degrees for all mineralized zones, except Goldfield Main which varied between 25 and 35 degrees depending on slope orientation. Processing Costs: Processing costs were estimated based on crushing and metallurgical testing. Processing costs for run-of-mine (“ROM”) material range from $3.03/t to $4.99/t. Processing costs for crushed material range from $5.06/t to $7.02/t. Recovery: Recoveries were estimated by laboratory testing of representative samples including bottle roll and column leach tests. Recoveries for ROM material range from 54% to 69%. Recoveries for crushed material range from 51% to 87%. Cut-off Grades: Cut-off grades for ROM material range from 0.10g/t to 0.16g/t. Cut-off grades for crushed material range from 0.12 g/t to 0.24 g/t. No dilution factor was applied as the selective mining unit (“SMU”) is expected to account for operational dilution and reflects the equipment sizing and capabilities. The Gemfield pit includes a volume of “must take” mineralized material (662,157 tonnes and 6,469 contained ounces) for permitting and closure purposes which lies outside the optimized pit shell. This material is included in the Gemfield reserve pit and economic analysis. Royalties applied: Gemfield 5%, Goldfield Main 4%, Jupiter 2.9%, McMahon Ridge 3% Goldfield Resources Mineral resources are reported in metric tonnes based on a gold price of $2,400/oz. The open pit mineral resources are constrained by a pit shell and are reported based on cut-off grades reported below that take into consideration metallurgical recoveries and selling costs. Mining Cost: A base mining cost of $3.43/t was used with an incremental haulage costs of $0.31/t and $0.35/t applied to Goldfield Main and McMahon Ridge respectively. A G&A cost of $0.55/t was applied for constraining the pit shell. Processing Costs: Processing costs were estimated based on crushing and metallurgical testing. Processing costs for ROM material range from $3.03/t to $4.87/t. Processing costs for crushed material range from $5.35/t to $7.32/t. Cut-off Grades: Cut-off grades for ROM material range from 0.08 g/t to 0.12 g/t. Cut-off grades for crushed material range from 0.10 g/t to 0.20 g/t. No royalty costs were applied to the resource estimate. Sulphide Resources: Laboratory testing has shown that material classified as sulphide can be recovered from the Goldfield and McMahon Ridge zones with crushing. Processing costs, recoveries and cut-off grades for sulphide materials as follows – Goldfield Main: Crushed processing cost $9.59/t, recovery 51%, cut-off grade 0.26 g/t; McMahon Ridge: Crushed processing cost $7.89/t, recovery 37%, cut-off grade 0.30 g/t.
