Nature of operations

Centerra Gold Inc. (“Centerra” or the “Company”) was incorporated under the Canada Business Corporations Act on November 7, 2002. Centerra’s common shares are listed on the Toronto Stock Exchange under the symbol “CG” and on the New York Stock Exchange under the symbol “CGAU”. The Company is domiciled in Canada and its registered office is located at 1 University Avenue, Suite 1800, Toronto, Ontario, M5J 2P1. The Company is primarily focused on operating, developing, exploring and acquiring gold and copper properties in North America, Türkiye, and other markets worldwide.

Basis of presentation

These unaudited condensed consolidated interim financial statements (“interim financial statements”) of the Company and its subsidiaries have been prepared in accordance with International Financial Reporting Standards (“IFRS”), International Accounting Standard 34, Interim Financial Reporting (“IAS 34”), as issued by the International Accounting Standards Board (“IASB”). These interim financial statements do not contain all of the annual disclosures required by IFRS, and should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2024.

These financial statements were authorized for issuance by the Board of Directors of the Company on October 28, 2025.

Summary of material accounting policies

These interim financial statements have been prepared using material accounting policies and critical accounting estimates and judgments consistent with those used in the Company’s audited consolidated financial statements as at and for the year ended December 31, 2024 except for:

Equity Investments

Equity investments expected to be held for more than twelve months after end of the reporting period are classified as non-current financial assets, and an irrevocable election has been made to measure certain securities at fair value through other comprehensive income. The unrealized gains or losses related to changes in fair value of the these investments are reported through other comprehensive (loss) income line in the condensed consolidated interim statements of earnings and comprehensive income. The election is made on an investment-by-investment basis.

New standards and amendments issued and applicable to the Company are described below:

IFRS 18, Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, the new standard on presentation and disclosure in financial statements, with a focus on updates to the statement of profit or loss. The key new concepts introduced in IFRS 18 relate to:

–the structure of the statement of profit or loss;

–required disclosures in the financial statements for certain profit or loss performance measures that are reported outside an entity’s financial statements (that is, management-defined performance measures);

–enhanced principles on aggregation and disaggregation of totals and disclosures which apply to the primary financial statements and notes in general.

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

IFRS 18 will replace IAS 1 while many of the other existing principles in IAS 1 are retained, with limited changes. IFRS 18 will not impact the recognition or measurement of items in the financial statements, but it might change what an entity reports as its ‘operating profit or loss’.

IFRS 18 will apply for reporting periods beginning on or after January 1, 2027 and also applies to comparative information. The Company is currently assessing the impact of this new standard on its financial statements prior to the effective date of January 1, 2027.

Impairment reversal

Goldfield Project

In the fourth quarter of 2024, following the completion of the updated mineral resource estimate, the Company determined that, based on the size and quality of the resource as well as the associated capital requirements, development of the project on a stand-alone basis was not economically viable under prevailing long-term gold price assumptions. The Company identified this as an indicator of impairment, performed an impairment test and concluded that the carrying amount of the Goldfield Project exceeded its estimated recoverable amount and recognized an impairment loss of $193.6 million during the year ended December 31, 2024.

During 2025, the Company completed additional technical studies and project optimizations on the Goldfield Project which in conjunction with a significant increase in long-term gold prices, significantly improved the economics of the project. On August 6, 2025, the Company’s Board of Directors approved the construction of the Goldfield Project and the Company announced the results of a technical study outlining strong economics for the Goldfield Project. Concurrent with the construction decision, the Company entered into zero-cost gold collars to hedge the commodity price risk, protect margins, safeguard economics in the early years of the Goldfield Project, and expedite the capital payback period. The Company identified the construction decision as indicators of impairment reversal for the Goldfield Project and completed an impairment reversal test in the third quarter of 2025. See note 18 for the details of the Company’s hedging program related to the Goldfield Project.

The estimated recoverable amount of the Goldfield Project as at August 6, 2025 was determined on the basis of fair value less costs of disposal (“FVLCD”) and calculated by discounting the estimated future net cash flows over the estimated life of the mine. Calculating the FVLCD required management to make estimates and assumptions with respect to future production levels and operating and capital costs in the life of mine plans, future metal prices, discount rate and estimates of the fair value attributable to mineralization in excess of life of mine plan. Changes in any of the assumptions or estimates used in determining the fair values could have impacted the impairment reversal analysis and its conclusions. The key assumptions used in the impairment test for Goldfield Project are summarized in the table below:

	2025
Gold price per oz - medium term(1)	2,850 -3,050
Gold price per oz - long-term(1)	2,650
Discount rate	8.5

All values are in US Dollars.

(1)Gold prices represent anticipated realized metal prices. Medium term represents the early production years 2028 to 2030, whereas long term represents years from 2031 to the end of life of mine. Prices selected for 2029 and 2030 were developed in consideration of real hedged floor price of the zero-cost collars entered into for hedging purposes.

As the Goldfield Project’s estimated recoverable amount exceeded the previous carrying amount less amortization that would have been recognized had the assets not been impaired, an impairment reversal

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

of $193.5 million was recognized in the impairment reversal line item in the condensed consolidated interim statements of earnings and reflected in the "Corporate and other” category in the Company’s segment disclosure (note 19). This impairment reversal represents the full reversal of prior impairment allocated to long-lived assets, as adjusted for depreciation, depletion and amortization. The discounted cash flow approach uses significant unobservable inputs and is therefore considered Level 3 fair value measurement under the fair value hierarchy.

Key assumptions

The determination of the recoverable amount with Level 3 input of the fair value hierarchy, includes the following key applicable assumptions:

•Gold price estimates were determined using forecasts of future prices prepared by industry analysts, which were available as at or close to the valuation date;

•Estimated production levels, and future operating and capital costs are based on detailed life of mine plans and also take into account the Company’s expected development plans and development timeline to construct the necessary infrastructure and start production. The production levels used were consistent with the reserves volumes developed as part of the Company’s process for the estimation of mineral reserves and resources;

•A real after-tax discount rate was based on the Company’s estimated real weighted-average cost of capital, of which the two main components are the cost of equity and the after-tax cost of debt. The discount rate was adjusted for the specific risks associated with the Goldfield Project.

Sale of Greenstone Partnership

In 2021, the Company sold its interest in the Greenstone Partnership for consideration which included contingent payments dependent on achieving certain cumulative production milestones. On November 6, 2024, Equinox Gold Inc. (“Equinox”), the operator of the Greenstone Mine, announced that the mine had achieved commercial production which removed significant uncertainty constraining the cumulative production milestones. As a result, the Company recognized an additional gain on the sale of Greenstone Partnership of $62.3 million and a contract asset, representing the amount due from Equinox under these payments contingent on achieving these production milestones. Subsequent to the initial recognition, the most likely value of the contract asset is re-measured at each reporting date with changes in expected value recorded as a gain or loss on the sale of Greenstone Partnership.

During the quarter, the Greenstone Mine achieved the first production milestone removing the constraint on the first tranche of the amount due from Equinox. On October 2, 2025, Equinox paid $41.0 million to the Company which is recorded in amounts receivable as at September 30, 2025. See note 6.

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

The table below summarizes changes in the contract asset included in other current assets and other non-current assets in the Company’s consolidated statements of financial position. The determination of other current and other non-current assets was based on the expected timing of receipt of contingent payments due from Equinox.

Balance, November 6, 2024	$	62,280
Remeasurement gain	808
Balance, December 31, 2024	$	63,088
Remeasurement gain	37,871
Amount reclassified to Amounts Receivable (note 6)	(41,044)
Balance, September 30, 2025	$	59,915
Current portion of amount due from Equinox (note 7)	$	30,377
Non-current portion of amount due from Equinox (note 9)	$	29,538

The most likely amount of the contract asset was determined using a discounted cash flow method. The key assumptions used in the measurement of the remaining contract asset (exclusive of the receivable from Equinox included in amounts receivable) are summarized in the table below:

	September 30, 2025	December 31, 2024
Gold price per oz	2,850	2,000
Timing of receipt of remaining contingent payments	2026	2025 to 2026
Discount rate	5.56	5.56

All values are in US Dollars.

Key assumptions

The determination of the most likely amount of the contract asset was performed utilizing Level 3 inputs of the fair value hierarchy, and including the following key assumptions:

•Future commodity price estimates were determined using forecasts of future prices prepared by industry analysts, which were available as at or close to the valuation date. The Company established a range of conservative data points between minimum and median of available future price estimates to reduce the likelihood of future reversal of the gain recognized on the sale of Greenstone Partnership.

•Expected timing of receipt of contingent payments were determined using the most recent production data for the Greenstone Mine and recently issued technical reports to estimate when the timing of the contingent payment thresholds would be met.

•Discount rate was based on a credit-risk adjusted rate representing the broader mining industry. This discount rate is not subject to change as the asset is re-measured on a periodic basis.

Future commodity prices and discount rate were assumptions applicable to all components of the measurement of the contract asset while production levels were a key assumption in the timing of the receipt of the milestone payments.

Shareholders' equity

a.Repurchases and cancellation of shares

Normal Course Issuer Bid (“NCIB”)

On November 5, 2024, the Company announced that it had received approval from the Toronto Stock Exchange (”TSX”) to renew its NCIB program. Under the renewed NCIB, Centerra may purchase for cancellation up to an aggregate of 18,800,929 common shares in the capital of the Company during the twelve-month period commencing on November 7, 2024 and ending on November 6, 2025, representing approximately 10% of the public float.

During the nine months ended September 30, 2025, the Company repurchased 9,195,416 common shares (2024 - 4,965,300 common shares), for total consideration of $64.0 million (2024 - $31.8 million) at an average price of $6.96 (C$9.69) (2024 - $6.41) per share. The total consideration paid for the cancelled shares, including transaction costs, was treated as a reduction to common share capital.

Automatic Share Purchase Plan

On September 29, 2025, the Company initiated an automatic share purchase plan (“ASPP”) under its NCIB by authorizing its independent broker to repurchase a fixed total value of Centerra common shares up to $7.0 million (December 31, 2024 - $7.6 million) with a certain share price limit during the period ending October 30, 2025.

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

The Company recognized a financial liability associated with the total maximum amount that may be repurchased during that period by the broker, with an offsetting entry in share capital.

(2)Relates to the Company’s Performance Share Unit (“PSU”) Plan.

For the three and nine months ended September 30, 2025 and 2024, certain potentially anti-dilutive securities were excluded from the calculation of diluted earnings per share due to the exercise prices being greater than the average market price of the Company’s common shares for the respective periods.

Anti-dilutive securities excluded from the calculation are summarized below:

	Three months ended September 30,		Nine months ended September 30,
	2025	2024	2025	2024
RSUs and stock options excluded from earnings per share (in thousands)	1,768	688	1,382	—
ASPP impact excluded from earnings per share (in thousands)(1)	649	703	649	703

(1) ASPP has an anti-dilutive impact on earnings per share by reducing the number of shares outstanding from the calculation.

c.Dividends

On October 29, 2025, the Board approved a quarterly dividend of C$0.07 per share to shareholders of record on November 13, 2025.

Commitments and contingencies

Commitments

As of September 30, 2025, the Company had entered into contracts to acquire PP&E totaling $43.1 million (September 30, 2024 - $17.4 million).

Contingencies

On an ongoing basis, the Company is subject to various claims, tax audits and other legal disputes, the outcomes of which cannot be assessed with a high degree of certainty.

Mount Milligan Mine Royalty

The Company is subject of a claim made by H.R.S. Resources Corp. (“H.R.S.”), the holder of a 2% royalty at Mount Milligan, in the first quarter of 2020. H.R.S. claimed that since November 2016 (when the royalty became payable) the Company has incorrectly calculated amounts payable under the royalty agreement and has therefore underpaid amounts owing to H.R.S. The B.C. Supreme Court rendered a written decision on October 8, 2024, which determined that the Company was correct to include the effect of the Royal Gold Streaming Agreement in its calculation of revenue subject to the royalty but that such revenue (for purposes of the royalty agreement) should have included amortized amounts relating to advance payments made by Royal Gold to TCM. In October 2025, the Court of Appeal for British Columbia heard an appeal and cross appeal of the B.C. Supreme Court’s decision. The Court of Appeal’s judgment was reserved. The Company believes the potential exposure in relation to this claim from what the Company has accrued is not materially different.

a.Mount Milligan Mine financial asset related to the Additional Royal Gold Agreement

The Mount Milligan Mine is subject to an arrangement with Royal Gold and Royal Gold, Inc. which entitles Royal Gold to purchase 35% and 18.75% of gold and copper produced, respectively, and requires Royal Gold to pay $435 per ounce of gold and 15% of the spot price per pound of copper delivered.

On February 13, 2024, the Company and its subsidiary, TCM, entered into an additional agreement with Royal Gold (the “Additional Royal Gold Agreement”) relating to the Mount Milligan Mine to increase cash payments for the Mount Milligan Mine’s gold ounces and copper pounds delivered to Royal Gold dependent on specific delivery milestones.

On September 11, 2025, the Company issued the Mount Milligan Mine pre-feasibility study (“MTM PFS”), confirming a life of mine extension by approximately 10 years to 2045. The fair value of the financial asset was re-measured during the period to incorporate the extension to the life of mine.

The following is a summary of the changes in the financial asset included in other assets in the Company’s consolidated statements of financial position:

Balance, February 13, 2024	$	19,200
Settlements during the period(1)	24,500
Fair value adjustments	23,500
Balance, December 31, 2024	$	67,200
Fair value adjustments	29,100
Balance, September 30, 2025	$	96,300

(1)Represents the initial $24.5 million cash payment made during the period.

The Company has also indemnified Royal Gold and its affiliates for up to $25 million of specified incremental taxes that may be assessed as a result of the Additional Royal Gold Agreement for a period of seven years. The Company considered the value associated with the indemnification to be nominal in its valuation of the financial asset based on remote probability of the cash outflow. The Company will continue to re-evaluate this assessment each period.

Subsequent to the period end, the first tranche of the $43.1 million deferred gold consideration was settled with Royal Gold as a result of the first production milestone for the Greenstone Mine being achieved. See note 5.

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

The key assumptions used in the measurement of the financial asset are summarized in the table below:

	September 30, 2025	December 31, 2024
Gold price per oz - short-term (1)	3,000 - 3,300	2,400 - 2,625
Gold price per oz - long-term	2,650	2,100
Copper price per lb - long term	4.25	4.25
Timing of delivery of Deferred Gold Consideration (range of years)	2025 to 2034	2025 to 2034
Gold price volatility used in the Monte Carlo simulation	17.3	12.0
Discount rate	6.25% - 7.5%	6.75

All values are in US Dollars.

(1) Short-term represents the years 2025-2028 as at September 30, 2025 (2024-2028 as at December 31, 2024).

Key assumptions

The determination of the fair value of the financial asset was performed utilizing Level 3 inputs of the fair value hierarchy, and including the following key assumptions:

•Future commodity price estimates were determined using forecasts of future prices prepared by industry analysts, which were available as at or close to the valuation date and applying the Monte Carlo method to determine the applicable price for the additional cash payments for gold;

•Discount rate was based on the Company’s estimated weighted-average cost of capital, of which the two main components are the cost of equity and the after-tax cost of debt. Included in the weighted-average cost of capital is the incremental premium reflecting risk associated with permitting and construction of the second tailings storage facility;

•Timing of Deferred Gold Consideration was determined based on the Company’s best estimate of the timing to receive the gold ounces in relation to the sale of Centerra’s 50% interest in the Greenstone Partnership;

•Gold price volatility used in the Monte Carlo simulation was determined by applying statistical methods to daily historical gold prices over the period equal to the life of Mount Milligan Mine; and

•Estimated future production profile, including production levels and operating and capital costs of the Mount Milligan Mine were determined with reference to the life of mine plan. The life of mine plan was updated in the third quarter of 2025 when the Company issued the MTM PFS. The production levels used were consistent with the volume of reserves developed as part of the Company’s process for the estimation of mineral reserves and resources.

Future commodity prices and discount rate were assumptions applicable to all components of the measurement of the financial asset while production levels were a key assumption in the valuation of Threshold Payments and Free Cash Flows Interest Payments components of financial asset. Gold price volatility was an assumption used specifically in the Monte Carlo method applied in the valuation of additional cash payments for gold.

b.Derivative financial instruments

The Company uses derivative financial instruments as part of its risk management program to mitigate exposures to various market risks including commodity prices, foreign exchange rates and diesel fuel prices. The Company’s derivative counterparties are syndicate members of the Company’s corporate credit facility. The Company monitors its derivative position exposures on an ongoing basis.

(3)Hedges associated with the Goldfield Project with floors at $3,200 for 2029 and 2030, with ceilings at an average of $4,438 and $4,705, respectively.

Fuel contracts

The Company applies hedge accounting to derivative instruments it enters into to hedge a portion of its estimated future diesel fuel purchases at its Mount Milligan Mine operations and estimated future diesel fuel purchases at the Thompson Creek Mine, to manage the risk associated with changes in diesel fuel prices on the cost of operations. The fuel hedge contracts are expected to settle over time by the end of 2027.

Foreign exchange contracts

The Company applies hedge accounting to the foreign exchange contracts it enters into to hedge a portion of its future Canadian dollar denominated expenditures. The foreign exchange contracts are expected to settle over time by the end of 2027.

Gold contracts

In 2024, the Company entered into zero-cost collar contracts for 40,000 ounces in 2025 and 20,000 ounces in 2026. The derivatives expire evenly through each year.

In conjunction with the decision to proceed with the Goldfield Project on August 6, 2025, the Company entered into zero-cost collar contracts for 57,000 ounces in 2029 and 60,000 ounces in 2030 to protect project economics and support predictable cash flow during the ramp-up period. These contracts are expected to settle over time by the end of 2030.

The Company applies hedge accounting to gold contracts it enters to hedge a portion of the expected gold ounces sold to manage the risk associated with changes to the London Bullion Market Association (“LBMA”) gold price. The option collar contracts utilize a price floor, allowing for significant participation in

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

upward price movements. These hedges result in cash inflows or outflows only when the underlying LBMA gold price is below the collar floor, or above the collar ceiling, respectively, at the time of settlement.

Non-hedge derivatives

The non-hedge derivative instruments outstanding as at September 30, 2025 are expected to settle by the end of the forth quarter of 2025, and are summarized as follows:

Instrument	Unit	Type	Total Position(1)
Royal Gold deliverables
Gold forward contracts	Ounces	Float	12,340
Copper forward contracts	Pounds	Float	3,252,000

(1)Total amounts expressed in the units identified.

Royal Gold deliverables

For deliveries under the Mount Milligan Streaming Agreement, the Company delivers physical gold and copper warrants to Royal Gold based on a percentage of the gold ounces and copper pounds included in each final sale of concentrate to third party customers, including off-takers and traders (collectively, “MTM Customers”), within two days of receiving or making a final payment. If a final payment from the MTM Customers is not received or paid within five months of the bill of lading date, then the Company will deliver an estimated amount of gold ounces and copper warrants, based on the quantities from the provisional invoice, for an estimated 90% of the material they are due to pay, based on the provisional invoice quantities.

The Company receives payment from the MTM Customers in cash, thus requiring the purchase of physical gold and copper warrants in order to satisfy the obligation to pay Royal Gold. In order to hedge its gold and copper price risk, which arises from timing differences, when physical purchase and concentrate sales pricing periods do not match, the Company has entered into certain forward gold and copper purchase and sales contracts, pursuant to which it purchases gold and copper at an average price during a quotation period, and sells gold and copper at a spot price. These contracts are treated as derivatives and are not designated as hedging instruments. The Company records its forward commodity contracts at fair value using a market approach based on observable quoted market prices.

c. Provisionally-priced contracts

Amounts receivable

Upon the shipment and sale of gold and copper concentrate to various off-takers, the Company typically receives a payment equal to an amount ranging from 90% to 95% of the contracted value of the contained metals, net of applicable treatment and refining charges, while the final settlement payment is not due for several months. The majority of molybdenum sales is not subject to provisional pricing; however, for a small number of shipments and sales of molybdenum products to customers, the Company receives a payment typically equal to an amount ranging from 90% to 100% of the contracted value of contained metal, net of applicable deductions, while the remaining payment, if any, is not due for several months.

Under the terms of these sales contracts, prices are subject to final adjustment, at the end of a future period, after control passes to the customer, based on quoted market prices during a quotation period

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

specified in the contract. At the end of each reporting period, provisionally-priced receivables are marked to market based on the forward market price for the quotational period stipulated in the contract, with changes in fair value recognized in gold, copper and molybdenum revenue.

The amount of trade receivables related to the sales of gold and copper concentrate and molybdenum products prior to mark-to-market adjustment, the mark-to-market adjustment made during the period, and the fair value of provisionally-priced receivables as at September 30, 2025 and December 31, 2024, are summarized as follows:

Trade payables

Upon the purchase of molybdenum concentrate from various vendors, the Company typically pays an amount ranging from 95% to 100% of the contracted value of contained metal, net of applicable deductions while the final settlement payment is not due for several months. Under the terms of these concentrate purchase contracts, prices are subject to final adjustment at the end of a future period, after control passes to the Company based on quoted market prices during the quotation period specified in the contract. At the end of each reporting period, provisionally-priced purchases are recorded at fair value based on the forward market price for the quotation period stipulated in the contract, with changes in fair value recognized in inventory or production costs, as applicable.

Accounts payable related to the purchase of molybdenum concentrate prior to fair value adjustment, the fair value adjustments made during the period, and the fair value of provisionally-priced payables as at September 30, 2025 and December 31, 2024, are summarized as follows:

Valuation Techniques

Mount Milligan Mine financial asset related to the Additional Royal Gold Agreement

The fair value of the Mount Milligan Mine financial asset related to the Additional Royal Gold Agreement utilizes a combination of a Monte Carlo simulation method and discounted cash flow method. The fair value measurement requires management to make estimates and assumptions with respect to the metal prices, expected production, operating and capital costs from the Mount Milligan Mine’s life of mine

Centerra Gold Inc.<br><br>Notes to the Condensed Consolidated Interim Financial Statements (Unaudited)<br><br>September 30, 2025<br><br>(Expressed in thousands of United States dollars, except share and per share amounts, unless otherwise indicated)

projections, expected timing of delivery of Deferred Gold Consideration, gold price volatility used in the Monte Carlo simulation, probability of tax indemnity payments and a discount rate. As such, this financial asset is classified within Level 3 of the fair value hierarchy.

Equity investments

Equity investments representing shares of publicly traded entities are recorded at fair value using quoted market prices (classified within Level 1 of the fair value hierarchy).

Provisionally-priced receivables

The fair value of receivables arising from copper, gold and molybdenum sales contracts that contain provisional pricing mechanisms are determined using the appropriate quoted forward price from the exchange that is the principal active market for the particular metal. As such, these receivables, which meet the definition of an embedded derivative, are classified within Level 2 of the fair value hierarchy.

Provisionally-priced payables

The fair value of payables arising from molybdenum purchase contracts that contain provisional pricing mechanisms are determined using the appropriate quoted forward price from the exchange that is the principal active market for the particular metal. As such, these payables are classified within Level 2 of the fair value hierarchy.

Derivative financial instruments

The fair value of gold, copper, diesel and currency derivative financial instruments, classified within Level 2, are determined using derivative pricing models that utilize a variety of inputs that are a combination of quoted prices and market-corroborated inputs. The fair value of the Company’s derivative contracts includes an adjustment for credit risk.

Segmented information

The Company bases its operating segments on the way information is reported and used by the Company's chief operating decision-maker (“CODM”). The results of operating segments are reviewed by the CODM in order to make decisions about resources to be allocated to the segments and to assess their respective performances.

Overview of Consolidated Results

Third Quarter 2025 compared to Third Quarter 2024

Net earnings of $292.2 million were recognized in the third quarter of 2025, compared to net earnings of $28.8 million in the third quarter of 2024. The increase in net earnings was primarily due to:

•higher earnings from mine operations of $136.4 million recognized in the third quarter of 2025 compared to $107.4 million in the third quarter of 2024. The increase in earnings from mine operations was primarily due to higher average realized gold prices at the Öksüt Mine and higher average realized gold and copper prices at the Mount Milligan Mine. The increase was partially offset by slightly lower ounces of gold sold and higher royalty costs at the Öksüt Mine and lower gold ounces and copper pounds sold at the Mount Milligan Mine;

•an impairment reversal of $193.5 million, related to the Goldfield Project as a result of additional technical studies and project optimizations which in conjunction with increased long-term gold prices significantly improved the economics of the project;

•higher other operating income of $38.2 million in the third quarter of 2025 compared to an other operating expense of $8.0 million in the third quarter of 2024. The increase in the other operating income is primarily attributable to an unrealized gain of $42.6 million on the financial asset related to the additional agreement with RGLD Gold AG (together with Royal Gold, Inc., “Royal Gold”) dated February 13, 2024 to increase cash payments for the Mount Milligan Mine’s gold and copper delivered to Royal Gold based on the delivery of certain threshold amounts from shipments occurring after January 1, 2024 (“Additional Royal Gold Agreement”); and

•an unrealized gain of $16.3 million that was recognized in the third quarter of 2025 on the re-measurement of the amount due from Equinox Gold Corp. (“Equinox Gold”) in relation to the sale of Centerra’s 50% interest in the Greenstone Gold Mines Partnership in 2021, reflecting updated gold price assumptions related to the final portion of contingent consideration owing to the Company from Equinox Gold.

The increase in net earnings was partially offset by higher income tax expense of $59.6 million recognized in the third quarter of 2025 compared to income tax expense of $27.9 million in the third quarter of 2024 primarily due to a larger deferred tax expense of $28.9 million, stemming from a drawdown on deferred income tax assets related to earnings generated at the Mount Milligan Mine and the tax impact associated with the unrealized gain on the financial asset under the Additional Royal Gold Agreement.

Adjusted net earningsNG of $66.4 million were recognized in the third quarter of 2025, compared to adjusted net earningsNG of $38.6 million in the third quarter of 2024. As discussed above, the increase in adjusted net earningsNG was primarily due to higher earnings from mine operations, partially offset by higher income tax expense.

The main adjusting items to net earnings in the third quarter of 2025 were:

•$193.5 million related to the impairment reversal of the Goldfield Project;

•$27.4 million of unrealized gain, net of tax, on the financial asset related to the Additional Royal Gold Agreement;

•$14.0 million of deferred income tax adjustments reflecting primarily the impact of foreign exchange rate movement and changes in taxable differences on deferred tax assets at the Mount Milligan Mine;

•$16.3 million of unrealized gain on the re-measurement of the amount due related to the sale of the Company’s interest in the Greenstone Gold Mines Partnership in 2021; and

•$2.2 million of unrealized gain on current equity investments.

The main adjusting items to net earnings in the third quarter of 2024 were:

•$6.6 million of reclamation provision revaluation recovery resulting from the increase in the risk-free interest rates applied to discount the estimated provision for future reclamation cash outflows at the Thompson Creek Mine, Endako Mine and Kemess Project

•$1.5 million of unrealized loss on the financial asset related to the Additional Royal Gold Agreement; and

•$1.3 million of unrealized gain on foreign exchange from the movement in foreign currency exchange rates on the reclamation provision at the Endako Mine and Kemess Project and on the income tax payable and royalty payable at the Öksüt Mine.

Cash provided by operating activities was $161.7 million in the third quarter of 2025, compared to $103.6 million in the third quarter of 2024. The increase was primarily attributable to $29.0 million higher earnings from mine operations as discussed above and a $29.0 million favorable working capital change at the Mount Milligan Mine due to timing of vendor payments, including amounts due to Royal Gold. This was partially offset by a $14.8 million unfavorable working capital change at the Langeloth Facility due to build-up of inventory and increasing molybdenum prices.

Free cash flowNG of $98.7 million was recognized in the third quarter of 2025, compared to free cash flowNG of $37.4 million in the third quarter of 2024. The increase in free cash flowNG was primarily due to higher cash provided by operating activities as outlined above.

Nine months ended September 30, 2025 compared to September 30, 2024

Net earnings of $391.2 million were recognized in 2025, compared to net earnings of $132.9 million in 2024. The increase in net earnings was primarily due to:

•an impairment reversal of $193.5 million related to the Goldfield Project as outlined above;

•an unrealized gain of $37.9 million was recognized in 2025 on the re-measurement of the amount due from Equinox Gold in relation to the sale of Centerra’s 50% interest in the Greenstone Gold Mines Partnership in 2021, reflecting updated gold price assumptions related to the final portion of contingent consideration owing to the Company from Equinox Gold;

•higher other operating income of $17.3 million in 2025 compared to other operating expense of $30.4 million in 2024. The increase in the other operating income is primarily attributable to an unrealized gain of $29.1 million on the financial asset related to the Additional Royal Gold Agreement; and

•lower expensed exploration and evaluation costs of $37.4 million recognized in 2025, compared to $57.5 million in 2024. The decrease was primarily attributable to a $13.7 million decrease in project evaluation costs at the Thompson Creek Mine and a $5.3 million decrease in drilling and related costs at the Goldfield Project.

The increase in net earnings was partially offset by:

•a lower reclamation recovery of $3.0 million recognized in 2025 compared to a reclamation recovery of $23.5 million in 2024 primarily attributable to changes in the risk-free interest rates applied to discount the estimated provision for future reclamation cash outflows at the Endako Mine and Kemess Project. In addition, there was a reclamation recovery of $15.1 million recognized in 2024 at the Thompson Creek Mine from the increase in the risk-free interest rates applied to discount the estimated provision for future reclamation cash outflows. No reclamation expense or recovery was recognized at the Thompson Creek Mine in 2025 due to the commencement of development; and

•lower other non-operating income of $19.1 million recognized in 2025 compared to $33.1 million in 2024 primarily due to a $10.3 million lower unrealized foreign exchange gain attributable to a movement in foreign currency exchange rates and a $7.1 million decrease in interest income earned on the Company’s cash balance.

Adjusted net earningsNG of $145.4 million were recognized in 2025, compared to adjusted net earningsNG of $116.3 million in 2024. The increase in adjusted net earningsNG was due to lower expensed exploration and evaluation costs as outlined above and lower other operating expenses from decreased study costs, partially offset by lower other non-operating income as outlined above.

The main adjusting items to net earnings in 2025 were:

•$193.5 million related to the impairment reversal of the Goldfield Project;

•$37.9 million of an unrealized gain on the re-measurement of the amount due related to the sale of the Company’s interest in the Greenstone Gold Mines Partnership in 2021;

•$13.9 million of unrealized gain, net of tax, on the financial asset related to the Additional Royal Gold Agreement; and

•$3.2 million of reclamation provision revaluation recovery.

The main adjusting items to net earnings in 2024 were:

•$23.5 million reclamation provision revaluation recovery, as noted above;

•$10.4 million of unrealized loss on the financial asset related to the Additional Royal Gold Agreement;

•$4.5 million of deferred income tax adjustments mainly resulting from the impact of foreign exchange rate movements on the deferred income tax balances at the Öksüt Mine and the Mount Milligan Mine;

•$2.1 million of unrealized gain on foreign exchange from the effect of movement in foreign currency exchange rates on the reclamation provision at the Endako Mine and Kemess Project and on the income tax payable and royalty payable at the Öksüt Mine; and

•$2.5 million of transaction costs related to the Additional Royal Gold Agreement.

Cash provided by operating activities was $245.6 million in 2025 compared to $205.6 million in 2024. The increase in cash provided by operating activities was primarily due to $20.1 million lower expensed exploration and evaluation costs as discussed above, $30.4 million in lower income tax payments at the Öksüt Mine, a $29.0 million favorable working capital movement at the Mount Milligan Mine due to timing of vendor payments, including amounts due to Royal Gold, and a $17.0 million decrease in cash used in operating activities at the Thompson Creek Mine due to the commencement of capitalization of certain costs after the restart decision. The increase was partially offset by $14.8 million higher production costs and $9.3 million higher royalty payments at the Öksüt Mine and a $16.8 million unfavorable working capital change at the Langeloth Facility due to a build-up of inventory and increasing molybdenum prices.

Free cash flowNG of $83.1 million was recognized in 2025 compared to free cash flowNG of $91.6 million in 2024. The decrease in free cash flowNG was primarily due to higher property, plant and equipment additions primarily related to a $58.4 million increase in capital spending at the Thompson Creek Mine, partially offset by higher cash provided by operating activities as outlined above.

Recent Events and Developments

Mount Milligan Mine Pre-Feasibility Study

On September 11, 2025, Centerra issued a news release that provided the results of the Mount Milligan Mine pre-feasibility study (“MTM PFS”), confirming a life of mine extension by approximately 10 years to 2045, supported by an optimized mine plan estimating 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. Centerra’s recent infill drilling program, targeting tighter drill spacing in key areas of the deposit, has been incorporated into the MTM PFS, improving confidence in the geology and mine plan. Proven and probable reserves 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 which will be achieved through the construction of a second tailings storage facility (“TSF”) planned north of the existing TSF. The TSF footprint has been designed to accommodate future lifts, providing flexibility for potential further life of mine extensions.

The MTM PFS has outlined key operational improvements, to support longer haul distances, higher material movement, and stockpile development, with increased mining rates enabled through the purchase of five additional haul trucks. The MTM PFS also outlines investment in mill motor upgrades and flotation cells to increase process plant throughput by about 10% to 66,300 tonnes per day and increase recovery by approximately 1%, respectively.

Non-sustaining capital expendituresNG of $186 million are planned for the life of mine extension with most of these costs expected to be incurred in the early-to-mid 2030s and expected to be fully funded from available liquidity and future cash flow from operations. The primary investment relates to the construction of the second TSF of $114 million slated for years 2032 and 2033. Approximately $36 million of non-sustaining capitalNG will be spent on process plant expansion and approximately $28 million on fleet additions consisting of the five new haul trucks. The remaining $7 million is related to overall improvements to site infrastructure.

As Centerra looks to the future of Mount Milligan beyond 2036, the establishment of the new Mining and Critical Minerals Ministry is an encouraging step forward, demonstrating the Province of British Columbia’s commitment to streamlining permitting and regulatory processes for critical mineral projects. The Mount Milligan Mine was given a “fast-track” status by the Province of British Columbia in alignment with their commitments.

Goldfield Project Construction Decision

The Company has completed a technical study of the Goldfield Project, which outlined attractive economics of an after-tax net present value (5%) (“NPV5%”) of $245 million and an after-tax internal rate of return (“IRR”) of 30%, using a long-term gold price of $2,500 per ounce and including the impact of gold hedges on a portion of production in 2029 and 2030. The technical study forecasts a mine life of approximately seven years, average annual gold production of 100,000 ounces between 2029 and 2032, and a life of mine AISC of $1,392 per ounce. First production is expected by the end of 2028, and the production profile indicates a total of 533,000 ounces of gold production at head grade of 0.66 g/t and production costs of $1,077 per ounce over the life of mine.

Since the initial resource estimate was published for the Goldfield Project in February 2025, the gold price has increased significantly, supporting an updated long-term price assumption of $2,500 per ounce for the Goldfield Project’s economics. The Company has implemented a gold hedging strategy covering 50% of gold production in 2029 and 2030, with a gold price floor of $3,200 per ounce and an average gold price cap of $4,435 per ounce in 2029 and $4,705 per ounce in 2030 set to protect margins, safeguard economics in the early years of the Goldfield Project, and expedite the capital payback period, while preserving upside potential. This approach is designed to ensure predictable cash flow during the ramp-up phase, with almost 80% of life-of-mine production remaining unhedged and fully exposed to market prices.

Following the completion of additional technical work and project optimizations in July 2025, Centerra’s board of directors (the “Board”) approved the construction of the Goldfield Project in August 2025. The initial capital investment is estimated to be $252 million, to be funded by the Company’s existing liquidity, and the project is expected to benefit from a short timeline to first production by the end of 2028, and low execution risk given its relatively simple process flow sheet. Nevada, as a historic mining district, offers a stable regulatory environment, skilled workforce, and strong support for resource development.

Subsequent to the construction decision, the Company has continued work on advancing the project planning for early execution and permitting. The Company continues to focus on key project milestones such as detailed engineering and site establishment throughout the end of 2025 and into early 2026. The Company is also currently working on active recruitment of key management positions related to the Goldfield Project.

The Company performed an impairment reversal test in the third quarter of 2025 and recognized a full impairment reversal of $193.5 million in the period.

Kemess Project Resource Update and PEA

The Kemess property has substantial gold and copper resources in the highly prospective Toodoggone district with significant infrastructure already in place, including an approximately 380 kilometer 230 kilovolt power line to site, a 50,000 tonnes per day nameplate processing plant in need of refurbishment; site infrastructure including a camp, administration facilities, truck shop and warehouse, which will require refurbishment; and tailings storage using the previously mined pit as well as an existing facility which is capable of expansion. Complementing this existing infrastructure, it is anticipated that new crushing, conveying, and mine infrastructure will be required for open pit and underground operations.

During 2024, Centerra commenced evaluation of technical concepts and engineering trade-off studies for potential restart options at the Kemess Project. In the first half of 2025, the Company published an updated resource estimate. Gold mineral resources at the Kemess Project are estimated to contain 2.7 million ounces of measured and indicated resources and 2.2 million ounces of inferred resources. Copper mineral resources are estimated to contain 971 million pounds of measured and indicated resources and 821 million pounds of inferred resources. The updated resource is generally consistent with the Company’s previous understanding of the resource estimate.

The Company is currently advancing a preliminary economic assessment (“PEA”) which is now expected to be completed in the first quarter of 2026, and is expected to contain discussion of the risks and opportunities related to the Kemess Project. The current operating concept is a combined open pit (which is expected to be a traditional truck and shovel operation) and long-hole stoping underground mining operation, which is expected to utilize paste backfill of the stopes for stability and be less capital intensive and have a better cash flow profile than the previously permitted underground block cave concept. In addition, the Company is continuing to advance technical studies that include metallurgical testing for flowsheet optimization, mine plan optimization, materials handling infrastructure engineering, tailings design optimization, as well as initiation of environmental baseline studies. Early indications show potential for a long-life operation that takes advantage of the significant existing infrastructure and has lower execution risk compared with a typical greenfield project of this scale. The PEA is targeting a future operation with a potential annual production of approximately 250,000 gold equivalent ounces, which, combined with the Mount Milligan Mine, would provide the Company with two long life gold-copper assets in British Columbia.

Change to the Turkish Government State Royalty

The Öksüt Mine is subject to the Turkish Government State Royalty (“Turkish royalty”), which is a sliding scale royalty, applicable to gold and other metals. The Turkish royalty rates for gold were last increased in 2020 and tend to be reviewed by the government of Türkiye every few years. On July 24, 2025, the Turkish parliament passed certain amendments to the Turkish Mining Law, which included an updated Turkish royalty rate table reflecting an elevated gold price environment. Under this new amendment, the maximum gold price threshold which applies to the Turkish royalty was updated from $2,100 per ounce to $5,100 per ounce, among other things. The change in royalty rates was retrospective to the beginning of 2025, and the Company recognized an adjustment to true-up royalty costs in the third quarter of 2025 which amounted to $6.3 million for nine months ended September 30, 2025. The Turkish Mining Law continues to provide a reduction of 40% of the royalty amount payable for gold processed at refining facilities within Türkiye, which is the case for the Öksüt Mine.

Restart of the Thompson Creek Mine and Strategic Plan for the Molybdenum BU

On September 12, 2024, Centerra announced the results of the Thompson Creek Mine feasibility study (“TCM FS”), including a strategic, integrated business plan for its Molybdenum BU consisting of a restart of the Thompson Creek Mine and a commercially optimized plan for the Langeloth Facility.

At significantly increased production capacity, integrated with Thompson Creek Mine, the Langeloth Facility has the potential to generate higher returns and higher cash flows from operations. Following the completion

of a feasibility study and commercial optimization plan, the Board approved the full restart of operations at the Thompson Creek Mine and a progressive ramp-up of production at the Langeloth Facility.

The TCM FS estimated capital investment to restart the Thompson Creek Mine of approximately $397 million. The capital required is significantly de-risked due to an existing pit, advanced equipment rebuilds and purchases, and an existing process plant that requires modest upgrades and refurbishments. A majority of the anticipated capital expenditures is expected to be focused on capitalized stripping, plant refurbishments and mine mobile fleet upgrades. At current metal prices, the capital investment to restart the Thompson Creek Mine is being internally funded largely from cash flows provided by the Mount Milligan Mine and the Öksüt Mine.

Third Quarter 2025 Highlights of Restart Activities

Since the restart decision in September 2024, the Thompson Creek Mine achieved approximately 29% cost completion status with advancements in pre-stripping activities and mine equipment refurbishments and purchases, engineering studies, early mill works, and other site infrastructure. In the nine months ended September 30, 2025, the Thompson Creek Mine continued pre-stripping operations, detailed engineering work for the plant refurbishment with an engineering consulting firm, early mill refurbishment activities with the Thompson Creek Mine maintenance workforce, and advanced basic engineering work for the TSF.

The key milestones completed in the third quarter of 2025 include:

•Pre-stripping operations continued with 8.3 million tons moved;

•Detailed engineering work for the plant refurbishment with an engineering consulting firm was substantially completed, with advancement of long lead procurement packages and contracts;

•Mill refurbishment activities continued, with demolition of the combined ball mill sump and copper cementation plant, the painting work at the thickener and flotation area completed, draw hole liners and apron feeders re-installed and long lead packages awarded;

•Continued mobile fleet refurbishment with a focus on shovels;

•Detailed engineering work for the TSF continued as planned;

•Advanced construction of housing units in neighboring communities to increase housing capacity; and

•The project schedule continues to target first production in the second half of 2027, consistent with the feasibility study.

In the third quarter of 2025, the Company incurred non-sustaining capital expendituresNG of $31.4 million at the Thompson Creek Mine. Since the restart decision, non-sustaining capital expendituresNG incurred have totaled $113.3 million.

All values are in US Dollars.

Centerra maintains a strong cash position of $561.8 million as at September 30, 2025, ensuring sufficient liquidity to finance ongoing project activities and internal growth projects. The Company continues to expect to finance the majority of 2025 expenditures from the cash flows generated by the Mount Milligan Mine and the Öksüt Mine.

Normal Course Issuer Bid

On November 5, 2024, Centerra announced that the Toronto Stock Exchange had accepted the renewal of a normal course issuer bid (“NCIB”) to purchase for cancellation up to an aggregate of 18,800,929 common shares in the capital of the Company during the twelve-month period commencing on November 7, 2024 and

ending on November 6, 2025. Any tendered common shares taken up and paid for by Centerra under the NCIB will be cancelled.

During the third quarter of 2025, the Company repurchased 2,839,983 common shares for a total consideration of $22.1 million (C$30.4 million) under its NCIB program. During the nine months ended September 30, 2025, the Company repurchased 9,195,416 common shares for total consideration of $64.0 million (C$89.1 million) under its NCIB program.

The Board has increased the approved level of share repurchases under the NCIB in 2025 to up to $100 million.

Exploration Update

Exploration activities during the quarter included drilling, surface rock and soil sampling, geological mapping and geophysical surveying at the Company’s various projects and earn-in properties, targeting gold and copper mineralization in Canada, Türkiye, and the USA. The activities were primarily focused on drilling programs at the Mount Milligan Mine and the Kemess Project in British Columbia, and greenfield projects in Canada, USA, and Türkiye.

Mount Milligan Mine

The 2025 diamond drilling program was completed during the third quarter and comprised a total of 56,835 metres drilled from 200 drill holes for the nine months ended September 30, 2025. Resource expansion and brownfield exploration targets include zones on the western margin of the open pit. The drilling campaign was part of an in-fill and exploration drilling program to upgrade and expand resource classification dominantly along the western margins of the current Mount Milligan ultimate pit in the Goldmark, North Slope, Boundary and Saddle West zones. Results received show mineralization and potential for resource expansion west of the current ultimate pit, including the Goldmark, Saddle West, and Boundary zones. Assay results from the in-fill drilling program were incorporated into the MTM PFS resource model. An updated resource model is expected to be completed by the end of the fourth quarter of 2025.

Kemess Project

Drilling at the Kemess Project started during the latter part of the second quarter of 2025 and for the nine months ended September 30, 2025, a total of 24,100 metres from 73 drill holes were completed. The program includes in-fill drilling to upgrade resource classification and support the Kemess PEA study, as well as exploration and geotechnical drilling. Resource expansion and brownfield exploration include targets both west and east of the Kemess Underground deposit, including the Nugget, Central Ridge, and Offset zones.

2025 Outlook

The Company’s updated 2025 outlook, previously disclosed in the MD&A for the second quarter ended June 30, 2025 filed on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar, remains unchanged except for the following revisions:

•Depreciation, depletion and amortization for the Mount Milligan Mine has been revised downward to a new range of $50 to $60 million from the previous guidance range of $60 to $70 million reflecting the extension of the life of mine;

•Current income tax expense at the Öksüt Mine has been revised upward to a new range of $80 to $90 million from the previous guidance range of $40 to $50 million reflecting higher gold prices; and

•Cash tax payments for the Öksüt Mine have been revised upward to a range $80 to $90 million from the previous guidance range of $60 to $70 million, reflecting higher gold prices.

The updated guidance ranges for depreciation, depletion and amortization, current income tax expense and cash tax payments for the Öksüt Mine have been incorporated in the consolidated ranges for current income tax expense and cash tax payments. Except for the changes highlighted above, and unless otherwise specifically noted in the Outlook sections below, the rest of the Company’s outlook remains unchanged. At present, the Company does not anticipate a material impact from current import tariffs.

The Company’s updated full year 2025 outlook and comparative actual results for the nine months ended September 30, 2025 are set out in the following table:

1.Consolidated Centerra figures.

2.The Mount Milligan Mine is subject to an arrangement with RGLD Gold AG and Royal Gold Inc. (together, “Royal Gold”) which entitles Royal Gold to purchase 35% and 18.75% of gold and copper produced, respectively, and requires Royal Gold to pay $435 per ounce of gold and 15% of the spot price per metric tonne of copper delivered (“Mount Milligan Mine Streaming Agreement”). Using assumed market prices of $3,850 per ounce of gold and $4.50 per pound of copper for the fourth quarter of 2025, the Mount Milligan Mine’s average realized gold and copper price for that period would be $2,655 per ounce and $3.78 per pound, respectively, compared to average realized prices of $2,478 per ounce and $3.72 per pound in the nine months ended September 30, 2025, when factoring in the Mount Milligan Streaming Agreement and concentrate refining and treatment costs.

3.Gold production for 2025 at the Mount Milligan Mine assumes estimated recoveries of 60% to 62% down from 63% and 65% gold recovery estimates assumed in the previous guidance, and compares to actual gold recovery of 60.9% achieved in the nine months ended September 30, 2025. Copper production for 2025 assumes recovery 77% to 79% for copper, which is unchanged from assumptions underlying previous guidance, and compares to actual copper recovery of 76.7% achieved in the nine months ended September 30, 2025.

4.Unit costs include a credit for forecasted copper sales treated as by-product for all-in sustaining costsNG. Production for copper and gold reflects estimated metallurgical losses resulting from handling of the concentrate and metal deductions levied by smelters.

5.Units noted as ($/oz) relate to gold ounces.

Production Profile

In the nine months ended September 30, 2025, the Company reported consolidated gold and copper production of 204,463 ounces of gold and 37.4 million pounds of copper, respectively. Centerra’s full year 2025 consolidated gold production guidance of 250,000 and 290,000 ounces remains unchanged. Copper production is expected to be 50 to 60 million pounds for the full year of 2025 and is unchanged from the previous guidance.

Mount Milligan Mine

In the nine months ended September 30, 2025, the Mount Milligan Mine produced 103,477 ounces of gold and 37.4 million pounds of copper. While the full year gold production updated guidance remains unchanged at 145,000 to 165,000 ounces, annual gold production is expected to be near the lower end of the guidance range due to production challenges experienced in the nine months ended September 30, 2025, the impact of which was incorporated into the MTM PFS. The plant completed two major scheduled shutdowns in the first and third quarters of 2025, which were executed on time and on budget. In the nine months ended September 30, 2025, mining operations have encountered zones with more complex mineralization; however, gold grades remain above the average grade of the reserve and in line with the recently published MTM PFS. In the second quarter of 2025, Centerra commenced an infill and grade control drilling program which continued in the third quarter of 2025 to improve geological and mine plan confidence, contributing to a mine plan with greater visibility on grades moving forward. Sales and monetization of gold ounces and copper pounds are dependent on the timing of ocean vessels and may result in some timing differences between produced and sold ounces.

Öksüt Mine

In the nine months ended September 30, 2025, the Öksüt Mine produced 100,986 ounces of gold. For the full year of 2025, gold production at the Öksüt Mine is trending to the upper end of its guidance range of 105,000 and 125,000 ounces of gold. In the nine months ended September 30, 2025, gold production was in line with expectations. In the fourth quarter of the year, gold production is expected to decrease relative to average quarterly production in 2025 due to lower contained ounces expected to be stacked on the heap leach during the quarter as the grade of ore mined and processed will decrease and be more consistent with the average reserve grade. Gold sales are expected to closely follow gold production.

Cost Profile

In the nine months ended September 30, 2025, the Company’s consolidated gold production costs amounted to $1,312 per ounce. For the full year of 2025, the Company anticipates its consolidated gold production costs to range from $1,300 to $1,400 per ounce. The gold production costs per ounce in the nine months ended September 30, 2025 reflect updated royalty rates applicable to gold sales at the Öksüt Mine which are retroactive to January 1, 2025.

Consolidated all-in sustaining costs on a by-product basisNG were $1,604 per ounce in the nine months ended September 30, 2025. For the full year of 2025, the Company expects its consolidated all-in sustaining costs on a by-product basisNG to be in the range of $1,650 to $1,750 per ounce.

Mount Milligan Mine

In the nine months ended September 30, 2025, the Mount Milligan Mine reported gold production costs of $1,423 per ounce. Production costs per ounce for the remainder of the year are expected to be consistent with those reported for the nine months ended September 30, 2025. The Company anticipates the Mount Milligan Mine’s gold production costs to be within the guidance range of $1,350 to $1,450 per ounce. As part of the ongoing full asset optimization program, the Mount Milligan Mine has reduced operational costs and is actively pursuing opportunities to further reduce costs. These efforts are focused on several key areas including downtime minimization through equipment availability improvements, optimizing costs relating to grinding media, tires, major consumables, and spare parts through improvement of procurement strategies

and consumption optimization. Approximately 90% of the Mount Milligan Mine’s costs are sourced from Canadian vendors and the Company is continuously evaluating implications from the current tariff environment but does not expect significant impact from tariffs levied on imported goods.

Copper production costs at the Mount Milligan Mine were $2.13 per pound in the nine months ended September 30, 2025. For the full year of 2025, copper production costs are projected to be in the range of $2.00 to $2.50 per pound. Copper production costs in 2025 are expected to reflect a lower allocation of costs to copper production due to relative changes in the market price of gold and copper.

At the Mount Milligan Mine, all-in sustaining costs on a by-product basisNG were $1,298 per ounce in the nine months ended September 30, 2025. For the full year of 2025, all-in sustaining costs on a by-product basisNG are expected to range from $1,350 to $1,450 per ounce. All-in sustaining costs on a by-product basisNG per ounce for the full year are expected to trend to the lower end of the guidance range but all-in sustaining costs on a by-product basisNG in the fourth quarter of 2025 are expected to be slightly higher than those in the first nine months of 2025 due to remaining capital spending.

Öksüt Mine

In the nine months ended September 30, 2025, the Öksüt Mine reported gold production costs of $1,199 per ounce due to higher royalty costs driven by elevated gold prices and updated royalty rates. The Company is maintaining the Öksüt Mine’s full year 2025 gold production costs guidance range of $1,200 to $1,300 per ounce. Gold production costs per ounce are expected to trend higher in the fourth quarter of the year driven by lower gold ounces sold.

The Öksüt Mine’s all-in sustaining costs on a by-product basisNG were $1,573 per ounce in the nine months ended September 30, 2025. The Company expects the Öksüt Mine’s full year all-in sustaining costs on a by-product basisNG to be in the range of $1,675 to $1,775 per ounce. The Company expects all-in sustaining costs on a by-product basisNG per ounce to be relatively higher in the fourth quarter of 2025 than those in the first nine months of 2025, primarily due to lower gold ounces sold in the fourth quarter. The Company expects all-in sustaining costs on a by-product basisNG for the full year of 2025 to trend towards the lower end of the guidance range due to strong full year gold production.

Capital Expenditures

Additions to Property, Plant and Equipment (“PP&E”) include certain non-cash additions to PP&E such as changes in future reclamation costs and capitalization of leases. Capital expendituresNG, which comprise sustaining capital expendituresNG and non-sustaining capital expendituresNG, exclude such non-cash additions to PP&E. The reconciliation of additions to PP&E and capital expendituresNG is included in the Non-GAAP and Other Financial Measures section of this MD&A.

In the nine months ended September 30, 2025, consolidated additions to PP&E for gold and copper producing assets were $84.0 million and total capital expendituresNG for these assets were $74.0 million. For the full year of 2025, both consolidated additions to PP&E and total capital expendituresNG are planned to be in the range of $105 to $130 million. Total capital expendituresNG are expected to be relatively higher in the fourth quarter of 2025, primarily due to the timing of planned capital expendituresNG at the Mount Milligan Mine.

The Mount Milligan Mine’s additions to PP&E in the nine months ended September 30, 2025 were $52.2 million and total capital expendituresNG were $48.9 million. The difference between additions to PP&E and capital expendituresNG was mainly due to a change to future reclamation costs of $1.9 million. For the full year of 2025, the Mount Milligan Mine is expecting additions to PP&E and total capital expendituresNG to be in the range from $75 to $90 million. Total capital expendituresNG include sustaining capital expendituresNG in the range from $60 to $70 million and non-sustaining capital expendituresNG in the range from $15 to $20 million. A significant portion of the remaining 2025 sustaining capital expendituresNG relates to capitalized TSF construction costs amounting to the range of $5 to $10 million with the remaining sustaining capital expendituresNG largely related to water management projects and delivery of the remaining large truck boxes

to optimize payload and reduce future truck purchases. Non-sustaining capital expendituresNG planned for the fourth quarter of 2025 include purchases of additional mining equipment to meet the increased tonnage movement requirements in the future years of the Mount Milligan Mine’s life of mine.

The Öksüt Mine’s additions to PP&E in the nine months ended September 30, 2025 were $31.8 million and total capital expendituresNG were $25.1 million. The difference between additions to PP&E and capital expendituresNG was mainly due to a change to future reclamation costs of $5.1 million and the costs capitalized into right of use assets of $1.7 million. For the full year of 2025, the Öksüt Mine is expecting sustaining capital expendituresNG in the range of $30 to $40 million. Most of the remaining 2025 sustaining capital expendituresNG relate to capitalized stripping costs amounting to $5 to $10 million, phase 3 of the heap leach pad expansion, and a barren solution distribution system to improve the heap leach irrigation system.

Depreciation, Depletion and Amortization

In the nine months ended September 30, 2025, the Company’s DDA expense included in the cost of sales for gold and copper producing assets was $82.1 million. The Mount Milligan Mine’s DDA expense in the nine months ended September 30, 2025 was $45.3 million and the Öksüt Mine’s DDA expense was $36.8 million. For the full year of 2025, the Company estimates DDA expense to be in the range of $85 to $105 million, including $35 to $45 million at the Öksüt Mine and $50 to $60 million at the Mount Milligan Mine, which is lowered from the previous guidance of $60 to $70 million due to the extension of the life of mine.

Current Taxes and Tax Payments

The Mount Milligan Mine’s current British Columbia mineral tax expense in the nine months ended September 30, 2025 was $3.6 million and the cash taxes paid were $3.1 million. The difference between current tax expense and cash taxes paid is due to timing of tax payments. For the full year of 2025, Mount Milligan Mine’s current British Columbia mineral tax expense and tax payments are each expected to be in the range of $3 to $5 million.

The Öksüt Mine’s current income tax expense in the nine months ended September 30, 2025 was $61.5 million, including a withholding tax of $19.0 million on the repatriation of Öksüt Mine’s earnings. Total cash taxes paid by the Öksüt Mine in the nine months ended September 30, 2025 were $53.0 million, including a withholding tax of $19.0 million on the repatriation of Öksüt Mine’s earnings. The difference between current tax expense and cash taxes paid is due to timing of tax payments. For the full year of 2025, the Öksüt Mine income tax expense is expected to be in the range of $80 to $90 million, which is an increase from the previous guidance of $40 to $50 million, and is primarily driven by elevated gold prices. The income tax reflects a 25% income tax rate on taxable income. The Öksüt Mine is expected to pay approximately $80 to $90 million in cash taxes in 2025. This is an increase from the previous guidance of $60 to $70 million, reflecting a higher income tax expense in 2025.

Thompson Creek Mine

Since the restart decision in September 2024, significant progress has been made in advancing the project. The Thompson Creek Mine’s additions to PP&E and total capital expendituresNG in the nine months ended September 30, 2025 were $94.8 million and $83.7 million, respectively. The difference between additions to PP&E and capital expendituresNG was mainly due to a change to future reclamation costs of $1.6 million and capitalized DDA of $7.3 million. Since the restart decision in September 2024, non-sustaining capital expendituresNG have been $113.3 million including capitalized stripping costs of $59.1 million, equipment refurbishments and capital equipment purchases of $28.5 million, engineering studies of $9.0 million and other capitalized costs of $16.7 million. For the full year of 2025, the Thompson Creek Mine’s additions to PP&E and total capital expendituresNG are expected to be in the range of $130 to $145 million; however, based on the current rate of spending and the planned scopes of work in the fourth quarter of 2025, the Company expects capital expendituresNG to be at the lower end of the guidance range. Major activities contributing to the planned total capital expendituresNG for 2025 include:

•Progressive ramp-up of tons moved per month through the balance of 2025;

•Completion of remaining mine fleet refurbishments by the end of 2025;

•Detailed engineering and procurement of long-lead mill equipment substantially completed in the third quarter of 2025;

•Mobilization of equipment, materials and contractors necessary for the mill construction in the fourth quarter of 2025;

•Procurement and construction of housing units in the neighboring communities to facilitate increased mining workforce levels;

•Site infrastructure development and other costs; and

•Completion of basic engineering and substantial completion of detailed engineering for the TSF by the end of the year.

The project remains on track, with first production expected in the second half of 2027. The Company estimates that the majority of costs at the Thompson Creek Mine will relate to goods and services sourced domestically within the United States and, as such, does not anticipate a material impact from import tariffs at this time.

Langeloth Facility

In the nine months ended September 30, 2025, the Langeloth Facility roasted and sold 10.6 and 10.4 million pounds of molybdenum, respectively. The Langeloth Facility has continued the previously disclosed ramp-up of operations and is planning to increase roasting volumes to the range of 13 to 15 million pounds of molybdenum for the full year of 2025. The majority of the molybdenum products made at the Langeloth Facility are sold to large steel mills within the United States.

In the nine months ended September 30, 2025, Langeloth Facility’s loss from operations was $2.1 million, including DDA of $3.4 million, and adjusted EBITDANG was $1.4 million. For the full year of 2025, the Company expects the Langeloth Facility’s results to range from $3 million loss from operations to $5 million earnings from operations and expects to achieve a positive adjusted EBITDANG in the range of $2 to $8 million for the full year of 2025.

The Company expects that the cash provided by operations at the Langeloth Facility for the full year of 2025 will primarily be driven by adjusted EBITDANG and changes in working capital. The working capital requirements at the Langeloth Facility are highly dependent on market molybdenum prices. In the nine months ended September 30, 2025, average molybdenum market price increased from $21.08 per pound at the end of the fourth quarter of 2024 to $24.98 per pound at the end of the third quarter 2025 and the Langeloth Facility reported $16.8 million in incremental working capital investment partially due to the build-up of inventory necessary for the continuous capacity ramp-up and partially due to the increase in the average molybdenum market price. The Company expects and incremental release of working capital of approximately $20 million at a $5 decrease in molybdenum price and an investment in working capital of approximately $20 million at a $5 increase in molybdenum price.

In the nine months ended September 30, 2025, the Langeloth Facility’s additions to PP&E and total capital expendituresNG were $0.9 million. For the full year of 2025, the Langeloth Facility is projecting sustaining capital expendituresNG to be in the range of $2 to $4 million.

Endako Mine

In the nine months ended September 30, 2025, the Company's share of cash expenditures at the Endako Mine totaled $8.1 million, including $4.0 million for care and maintenance and $4.5 million for reclamation, partially offset by cash release from working capital movements of $0.4 million. For the full year of 2025, the Company’s share of care and maintenance expenditures at the Endako Mine are expected to be between $6 and $8 million and reclamation expenditures are expected to be $4 to $7 million.

1.Total and brownfield exploration costs include capitalized exploration costs at the Mount Milligan Mine of $7.9 million spent in the nine months ended September 30, 2025, and $7 to $9 million projected for the full year of 2025.

Exploration Expenditures (excluding Project Evaluation costs)

In the nine months ended September 30, 2025, total exploration expenditures were 39.3 million, including $31.4 million related to expensed exploration, and capitalized exploration costs of $7.9 million at the Mount Milligan Mine. For the full year of 2025, exploration expenditures are expected to be $40 to $50 million. The exploration expenditures include $25 to $30 million of brownfield exploration and $15 to $20 million of greenfield and generative exploration programs. Over 85% of exploration expenditures are expected to be expensed. The remaining 2025 exploration targets for brownfield projects include further drilling and test work at the Mount Milligan Mine, as well as the Kemess Project. At the Mount Milligan Mine, resource expansion and brownfield exploration targets included zones on the western margin of the open pit which will form the basis of a resource model update expected to be completed during the fourth quarter of the year. Planned exploration work at Kemess include the Kemess Underground project area and Kemess South. Exploration costs are expected to be lower in the fourth quarter of 2025 as a significant portion of drilling programs were prioritized during the earlier part of the year.

Kemess Project

The work program at the Kemess Project continues to be focused on project evaluation activities including resource in-fill and exploration drilling as well as technical studies.

In the nine months ended September 30, 2025, the Kemess Project’s expenditures amounted to $20.5 million, comprised of $9.8 million for care and maintenance costs, $8.4 million related to exploration, and $2.3 million related to technical studies.

For the full year of 2025, the Kemess Project’s expenditures are projected to be in the range of $13 to $15 million on care and maintenance, $10 to $12 million on exploration drilling, and $4 to $6 million on technical studies (included in the Evaluation Costs in the table above). The Company continues to evaluate concepts for the property as outlined in the Recent Events and Developments section of this MD&A and expects to publish the results of a PEA in the first quarter of 2026.

Goldfield Project

On August 6, 2025, the Board authorized the Goldfield Project for construction. Following the approval of the project, the work program for the remainder of 2025 at the Goldfield Project is focused on studies and field campaigns and progressing detailed engineering. The Goldfield Project’s expenditures are projected to be in the range of $4 to $7 million for the full year of 2025. In the fourth quarter of 2025, the Goldfield Project’s expenditures are projected to be in the $2 to $4 million range.

Other Items

In the nine months ended September 30, 2025, corporate and administration expenses were 23.5 million, excluding stock-based compensation expense of $10.9 million and corporate depreciation of $0.6 million. Corporate and administration expenses excluding stock-based compensation expense are expected to be in the range from $28 to $32 million for the full year of 2025.

As a result of the attainment of certain production thresholds of the Greenstone Mine, the Company is entitled to receive 33,333 additional contingent gold ounces (or equivalent cash payments) from Equinox Gold in relation to the sale of Centerra’s 50% interest in the Greenstone Gold Mines Partnership in 2021. Early in the fourth quarter of 2025, Centerra received a cash payment equivalent in value to 11,111 ounces of gold and 11,111 ounces of gold were delivered by the Company to Royal Gold as part of the Additional Royal Gold Agreement. The Company anticipates the remaining contingent payments to be received after 2025.

2025 Material Assumptions

Other material assumptions or factors not mentioned above but used to estimate production and costs for the remaining three months of 2025 after giving effect to the hedges in place as at September 30, 2025, include the following:

•market gold price of $3,850 per ounce ($3,300 per ounce in the previous guidance), and an average realized gold price at the Mount Milligan Mine of $2,655 per ounce ($2,297 per ounce in the previous guidance) after reflecting the Mount Milligan Streaming Agreement (i.e., 35% of the Mount Milligan Mine’s gold is sold to Royal Gold for $435 per ounce) and gold refining costs;

•market price of $4.50 per pound for copper ($4.00 per pound in the previous guidance). Realized copper price at the Mount Milligan Mine is estimated to average $3.78 per pound ($3.36 per pound in the previous guidance) after reflecting the Mount Milligan Streaming Agreement (18.75% of the Mount Milligan Mine’s copper is sold to Royal Gold at 15% of the spot price per metric tonne), and copper treatment and refining costs;

•molybdenum price of $25.00 per pound ($21.00 per pound in the previous guidance);

•exchange rates are as follows: $1USD:$1.37 CAD ($1USD:$1.36 CAD in the previous guidance), and $1USD:42 Turkish lira ($1USD:38 Turkish lira in the previous guidance); and

•diesel fuel price of $0.99 / litre or CAD$1.40 / litre at the Mount Milligan Mine ($1.02 / litre or CAD$1.39 / litre in the previous guidance) and $2.85/gallon at the Thompson Creek Mine.

The Additional Royal Gold Agreement is not expected to have a significant impact on these assumptions in 2025 as the increases in payments received by the Company for gold ounces and copper pounds delivered to Royal Gold are not expected to commence until approximately 2030.

Mount Milligan Streaming Agreement

Production at the Mount Milligan Mine is subject to the Mount Milligan Streaming Agreement. To satisfy its obligations under the Mount Milligan Streaming Agreement, the Company purchases refined gold and copper warrants and arranges for their delivery to Royal Gold. The difference between the cost of the purchases of refined gold and copper warrants, and the corresponding amounts payable to the Company under the Mount Milligan Streaming Agreement is recorded as a reduction of revenue and not a cost of operating the mine.

Other Material Assumptions

Production, cost, and capital expenditure forecasts for the fourth quarter of 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 from those estimated. Material assumptions used in forecasting production and costs for the fourth quarter of 2025 and related risk factors can be found under the heading “Cautionary Statement on Forward-Looking Information” in this document and under the heading “Risks That Can Affect Centerra’s Business” in the Company’s most recent Annual Information Form (“AIF”).

2025 Sensitivities

Centerra’s costs and cash flows for the remaining three months of 2025 are sensitive to changes in certain key inputs. The Company has estimated the impact of any such changes on its net income, capital costs and cash flows as follows:

		Impact on( millions)

Liquidity and Capital Resources

As of September 30, 2025, the Company’s total liquidity position was $961.8 million, representing a cash balance of $561.8 million and no amounts drawn under its $400.0 million corporate credit facility.

Third Quarter 2025 compared to Third Quarter 2024

See the Overview of Consolidated Results section in this MD&A for the discussion of cash provided by operating activities.

Cash used in investing activities of $87.8 million was recognized in the third quarter of 2025 compared to $67.4 million in the third quarter of 2024. The increase is primarily related to a cash payment of $24.9 million to make equity investments in the third quarter of 2025, including the investment in Liberty Gold Corp.

Cash used in financing activities in the third quarter of 2025 was $34.4 million compared to $24.3 million in the third quarter of 2024. The increase is primarily due to higher consideration paid to repurchase and cancel Centerra common shares. Consideration paid for the repurchase and cancellation of 2,839,983 Centerra common shares under the Company’s NCIB program was $22.1 million in the third quarter of 2025 compared to consideration of $12.0 million paid for the repurchase and cancellation of 1,741,800 Centerra common shares under the Company’s NCIB program in the third quarter of 2024.

Nine months ended September 30, 2025 compared to September 30, 2024

See the Overview of Consolidated Results section in this MD&A for the discussion of cash provided by operating activities.

Cash used in investing activities of $209.0 million was recognized in 2025 compared to $145.7 million in 2024. The increase is primarily related to $58.4 million higher capital spending at the Thompson Creek Mine in 2025 and $41.3 million higher purchase of equity investments in 2025, partially offset by a cash payment of $24.5 million related to the Additional Royal Gold Agreement executed in 2024.

Cash used in financing activities of $99.4 million was recognized in 2025 compared to $68.5 million in 2024. The increase was primarily due to higher consideration paid to repurchase and cancel Centerra common shares. Consideration paid for the repurchase and cancellation of 9,195,416 Centerra common shares under the Company’s NCIB program was $64.0 million in 2025 compared to consideration of $31.8 million paid for the repurchase and cancellation of 4,965,300 Centerra common shares under the Company’s NCIB program in 2024.

Financial Performance

Third Quarter 2025 compared to Third Quarter 2024

Revenue of $395.2 million was recognized in the third quarter of 2025 compared to $323.9 million in the third quarter of 2024. The increase in revenue was primarily due to higher average realized gold, copper and molybdenum prices and higher molybdenum pounds roasted and sold. The increase was partially offset by lower ounces of gold and pounds of copper sold at the Mount Milligan Mine.

Gold production was 81,773 ounces in the third quarter of 2025 compared to 93,712 ounces in the third quarter of 2024. Gold production in the third quarter of 2025 included 49,234 ounces of gold produced at the Öksüt Mine compared to 50,719 ounces produced in the third quarter of 2024. There were 32,539 ounces of gold produced from the Mount Milligan Mine in the third quarter of 2025 compared to 42,993 ounces in the third quarter of 2024. The decrease was primarily driven by lower throughput, lower head grades and lower gold recoveries.

Copper production at the Mount Milligan Mine was 13.4 million pounds in the third quarter of 2025 compared to 13.7 million pounds in the third quarter of 2024. The decrease in copper production was primarily due to lower mill throughput.

The Langeloth Facility roasted and sold 4.4 million pounds and 3.1 million pounds of molybdenum, respectively, in the third quarter of 2025, compared to 2.4 million pounds roasted and 2.4 million pounds sold in the third quarter of 2024. The increase in molybdenum roasted and sold in the third quarter of 2025, compared to the third quarter of 2024, was primarily due to strong demand from its main contract customers during the third quarter of 2025 and slightly slower ramp up of molybdenum production following the planned acid plant shut down executed in the second quarter of 2024. The increased volumes in 2025 are in line with the Company’s strategy to progressively ramp-up volumes at the Langeloth facility over time, including a goal to increase roasting volumes to the range of 13 to 15 million pounds in 2025.

Cost of sales of $258.8 million was recognized in the third quarter of 2025 compared to $216.6 million in the third quarter of 2024. The increase was primarily due to $25.8 million higher production costs at the Langeloth Facility resulting from higher pounds of molybdenum sold and higher cost of molybdenum purchased due to higher molybdenum prices. In addition, there were higher production costs at the Öksüt Mine mainly attributable to higher royalty costs.

Gold production costs were $1,346 per ounce in the third quarter of 2025 compared to $973 per ounce in the third quarter of 2024. The increase was primarily driven by lower ounces of gold sold at the Mount Milligan Mine, higher allocation of costs to gold production costs due to relative changes in the market price of gold

and copper, and higher royalty cost per ounce at the Öksüt Mine as a result of elevated gold prices and updated royalty rates.

All-in sustaining costs on a by-product basisNG were $1,652 per ounce in the third quarter of 2025 compared to $1,302 per ounce in the third quarter of 2024. The increase in all-in sustaining costs on a by-product basisNG was primarily due to higher gold production costs per ounce as noted above, partially offset by lower sustaining capital expendituresNG.

A non-cash impairment reversal of $193.5 million was recognized in the third quarter of 2025, related to the Goldfield Project. The Company completed additional technical studies and project optimizations on the Goldfield Project which in conjunction with increased long-term gold prices significantly improved the economics of the project. The Company performed the impairment test of impairment and subsequently determined that the impairment should be reversed.

Other operating income of $38.2 million was recognized in the third quarter of 2025 compared to other operating expense of $8.0 million in the third quarter of 2024. The increase in other operating income is primarily attributable to a $42.6 million unrealized gain on the financial asset related to the Additional Royal Gold Agreement.

An unrealized gain of $16.3 million was recognized in the third quarter of 2025 on the re-measurement of the amount due from Equinox Gold related to the sale of the Company’s 50% interest in the Greenstone Gold Mines Partnership, reflecting the updated gold price assumptions related to the contingent consideration owing to the Company.

The Company recognized income tax expense of $59.6 million in the third quarter of 2025, comprising current income tax expense of $30.6 million and deferred income tax expense of $29.0 million, compared to income tax expense of $27.9 million in the third quarter of 2024, comprising current income tax expense of $23.9 million and deferred income tax expense of $4.0 million. The increase in income tax expense in the third quarter of 2025 was primarily due to a larger deferred tax expense of $37.2 million, stemming from a drawdown on deferred income tax assets related to earnings generated at the Mount Milligan Mine and from the tax impact associated with the unrealized gain on the financial asset under the Additional Royal Gold Agreement.

Nine months ended September 30, 2025 compared to September 30, 2024

Revenue of $983.0 million was recognized in 2025 compared to $912.1 million in 2024. The increase in revenue was primarily due to higher average realized gold, copper and molybdenum prices and higher molybdenum pounds sold. The increase was partially offset by lower gold ounces and copper pounds sold at the Mount Milligan Mine and lower ounces of gold sold at the Öksüt Mine.

Gold production was 204,463 ounces in 2025 compared to 294,880 ounces in 2024. Gold production in 2025 included 103,477 ounces of gold from the Mount Milligan Mine compared to 129,919 ounces in 2024. The decrease was primarily due to lower gold head grades, lower gold recoveries and lower throughput. The Öksüt Mine produced 100,986 ounces of gold in 2025 compared to 164,961 ounces of gold in 2024. The decrease was primarily due to a higher production level in 2024 from processing the built-up heap leach inventory following the resumption of operations in June 2023.

Copper production at the Mount Milligan Mine was 37.4 million pounds in 2025 compared to 41.6 million pounds in 2024. The decrease in copper production was primarily attributed to lower copper head grades and throughput.

The Langeloth Facility roasted 10.6 million pounds and sold 10.4 million pounds of molybdenum in 2025 compared to 7.3 million pounds roasted and 8.1 million pounds sold in 2024. This increase was primarily due to increased sales volume to its contracts customers in 2025 and a planned acid plant shut down in 2024.

Cost of sales of $682.6 million was recognized in 2025 compared to $613.7 million recognized in 2024. The increase was primarily due to $62.9 million higher production costs at the Langeloth Facility resulting from higher pounds of molybdenum sold and higher cost of molybdenum purchased due to higher molybdenum prices.

Gold production costs were $1,312 per ounce in 2025 compared to $860 per ounce in 2024. The increase in gold production costs per ounce was primarily due to lower gold ounces sold at the Öksüt Mine and the Mount Milligan Mine, higher royalty costs at the Öksüt Mine and higher allocation of costs to gold production costs at the Mount Milligan Mine due to relative changes in the market price of gold and copper.

All-in sustaining costs on a by-product basisNG were $1,604 per ounce in 2025 compared to $1,103 per ounce in 2024. The increase was primarily due to higher gold production costs per ounce as discussed above.

Reclamation recovery was $3.0 million in 2025 compared to a reclamation recovery of $23.5 million in 2024. The difference was primarily attributable to changes in the risk-free interest rates applied to discount the estimated provision for future reclamation cash outflows at the Endako Mine and Kemess Project. In addition, there was a reclamation recovery of $15.1 million recognized in 2024 at the Thompson Creek Mine from the increase in the risk-free interest rates applied to discount the estimated provision for future reclamation cash outflows. No reclamation expense or recovery was recognized at the Thompson Creek Mine in 2025 due to the commencement of development.

An unrealized gain of $37.9 million was recognized in 2025 on the re-measurement of amount due from Equinox Gold, reflecting the updated gold price assumptions related to the contingent consideration owing to the Company.

Other operating income of $17.3 million was recognized in 2025 compared to other operating expense of $30.4 million in 2024. The increase in other operating income is primarily attributable to an $29.1 million unrealized gain on the financial asset related to the Additional Royal Gold Agreement compared to $10.4 million in unrealized loss in 2024.

Expensed exploration and evaluation costs were $37.4 million in 2025, compared to $57.5 million in 2024. The decrease in expensed exploration and evaluation costs was primarily due to $21.1 million lower project evaluation costs at the Thompson Creek Mine. No expensed exploration and evaluation costs were recognized at the Thompson Creek Mine in 2025 due to the commencement of development.

Other non-operating income of $19.1 million was recognized in 2025 compared to $33.1 million in 2024. The decrease in other non-operating income is primarily attributable to a $10.3 million lower foreign exchange gain driven by the effect of foreign exchange movements on the reclamation provision at the Endako Mine and Kemess Project, and a $7.1 million decrease in interest income earned on the Company’s cash balance.

In conjunction with the decision to proceed with the Goldfield Project, the Company entered into zero-cost collar contracts for 57,000 ounces in 2029 and 60,000 ounces in 2030, representing 50% of annual production in each year, to protect project economics and support predictable cash flow during the ramp-up period. These zero-cost option collars are settled on a monthly basis, against the London Bullion Market Association (“LBMA”) gold prices and have a gold price floor of $3,200 per ounce and an average gold price

cap of $4,438 per ounce in 2029 and $4,705 per ounce in 2030. The current fair value of these instruments reflects an unrealized loss from the significant upward movement in the underlying gold price in 2025.

In the first quarter of 2025, the Company initiated a diesel hedging program associated with the restart of operations at the Thompson Creek Mine in order to manage the risk associated with changes in diesel fuel prices. The hedge contracts cover a portion of estimated future diesel fuel purchases as part of the re-start and are expected to settle over time by June 2027.

As at September 30, 2025, Centerra has not entered into any off-balance sheet arrangements with special purpose entities, nor does it have any unconsolidated affiliates.

Cash as at September 30, 2025 was $561.8 million compared to $624.7 million as at December 31, 2024. The decrease was primarily attributable to the repurchase and cancellation of approximately 9,195,416 Centerra common shares under the Company’s NCIB program amounting to $64.0 million, dividends paid of $31.1 million, $46.8 million paid to purchase equity investments, partially offset by a free cash flowNG of $83.1 million during the nine months ended September 30, 2025.

Amounts receivable as at September 30, 2025 were $162.1 million compared to $75.0 million at December 31, 2024. The increase was primarily due to a reclassification of $41.0 million from other current assets, a $21.4 million increase in amounts receivable at the Langeloth Facility from increased sales due to higher average market molybdenum prices and a $24.7 million increase in amounts receivable from gold and copper concentrate sales at the Mount Milligan Mine due to a significant increase in gold prices at quarter-end, resulting in a large mark-to-market adjustment.

Total inventories as at September 30, 2025 were $293.8 million compared to $234.2 million at December 31, 2024. The increase was primarily due to $40.8 million higher molybdenum inventory at the Langeloth Facility from higher average market molybdenum prices and a build-up of inventory to support higher operating volumes. In addition, there was an increase in gold inventory build-up at the ADR circuit and the heap leach facility of $12.7 million at the Öksüt Mine.

The carrying value of PP&E as at September 30, 2025 was $1.37 billion compared to $1.10 billion as at December 31, 2024. The increase was primarily due to the additions of $180.4 million related to ongoing capital projects at the existing mines and projects, including capital equipment purchases, equipment refurbishments and pre-stripping costs, other general costs capitalized at the Thompson Creek Mine, $193.5 million non-cash impairment reversal at the Goldfield Project, partially offset by the depreciation and depletion of PP&E of $105.0 million in the normal course of operations.

Deferred income tax assets as at September 30, 2025 were $29.5 million compared to $60.1 million as at December 31, 2024. The decrease was primarily due to the drawdown of the deferred tax assets at the Mount Milligan Mine as a result of the higher earnings from operations.

Non-current equity investments as at September 30, 2025 were $85.5 million compared to $9.8 million as at December 31, 2024. The increase was primarily due to the purchase of equity investments amounting to

$46.8 million and a $28.9 million unrealized gain recorded in Other Comprehensive Income (“OCI”) due to increases in the market value of the equity investments portfolio.

Non-current financial assets as at September 30, 2025 were $96.4 million compared to $67.2 million as at December 31, 2024. The increase was primarily due to a $29.1 million change in fair value of the financial asset related to the Additional Royal Gold Agreement.

Accounts payable and accrued liabilities as at September 30, 2025 were $319.8 million compared to $233.1 million at December 31, 2024. The increase was primarily due to the effect of timing of vendor payments of $35.2 million including a higher payable due to Royal Gold at the Mount Milligan Mine, and timing of vendor payments, build-up of inventory and higher molybdenum prices on purchases at the Langeloth Facility amounting to $44.7 million.

Provision for reclamation as at September 30, 2025 was $284.0 million compared to $266.2 million as at December 31, 2024. The increase was primarily due to an $8.4 million accretion, a $7.5 million increase in the provision for future reclamation cash flows at the Öksüt Mine, Mount Milligan Mine and Endako Mine and $3.8 million due to the effect of the foreign exchange movement on the reclamation provision at the Endako Mine and Kemess Project.

Non-current financial liabilities as at September 30, 2025 were $45.4 million compared to $5.2 million as at December 31, 2024. The increase was primarily due to a 44.2 million mark-to-market adjustment on certain gold hedging contracts as a result of rising gold prices.

Share capital as at September 30, 2025 was $766.8 million compared to $826.7 million as at December 31, 2024. The decrease was primarily due to the repurchase and cancellation of shares for $64.0 million under the NCIB program.

Accumulated other comprehensive loss as at September 30, 2025 was $28.5 million compared to accumulated other comprehensive loss of $11.2 million as at December 31, 2024. The increase in accumulated other comprehensive loss was primarily due to the changes in the fair value of hedged derivative instruments on the hedging programs at the Goldfield Project and the Öksüt Mine of $54.2 million, partially offset by the increase of $28.3 million in fair value of the equity investments recorded in OCI.

Operating Mines and Facilities

Mount Milligan Mine

The Mount Milligan Mine is an open-pit mine located in north central British Columbia, Canada producing a gold and copper concentrate. The Mount Milligan Mine is subject to the Mount Milligan Mine Streaming Agreement. To satisfy its current obligations under the Mount Milligan Mine Streaming Agreement, the Company purchases refined gold ounces and copper warrants and arranges for delivery to Royal Gold. The difference between the cost of the purchases of refined gold ounces and copper warrants and the corresponding amounts payable to the Company under the Mount Milligan Streaming Agreement is recorded as a reduction of revenue rather than a cost of operating the mine. On February 13, 2024, the Company entered into the Additional Royal Gold Agreement, relating to the Mount Milligan Mine.

Third Quarter 2025 compared to Third Quarter 2024

Earnings from mine operations of $45.4 million were recognized in the third quarter of 2025 compared to $37.8 million in the third quarter of 2024. The increase in earnings from mine operations was primarily due to lower DDA and higher average realized gold and copper prices, partially offset by lower gold ounces and copper pounds sold. Lower DDA was due to an increase in proven and probable reserves as a result of the life of mine extension.

Cash provided by mine operations of $64.1 million was recognized in the third quarter of 2025 compared to $40.2 million in the third quarter of 2024. The increase was primarily due to a favorable working capital change, higher average realized gold prices, partially offset by lower gold ounces sold. The favorable working capital change in the third quarter of 2025 compared to the third quarter of 2024 was primarily related to the timing of vendor payments, including amounts due to Royal Gold.

Free cash flow from mine operationsNG of $44.6 million was recognized in the third quarter of 2025 compared to $15.6 million in the third quarter of 2024. The increase was primarily due to higher cash provided by mine operations as noted above and lower capital expendituresNG

During the third quarter of 2025, mining activities were carried out in phases 5, 6, 7 and 10 of the open pit. Total tonnes mined were 12.3 million tonnes in the third quarter of 2025 compared to 11.8 million tonnes in the third quarter of 2024. The increase in tonnes mined in the third quarter of 2025 was largely attributable to higher equipment availability compared to the same period in 2024.

Total process plant throughput in the third quarter of 2025 was 5.3 million tonnes, averaging 57,541 tonnes per calendar day compared to 5.6 million tonnes, averaging 60,354 tonnes per calendar day in the third quarter of 2024. The lower throughput was primarily due to more maintenance activities in the crushing circuit and slowdown events associated with operational challenges in the grinding circuit.

Gold production was 32,539 ounces in the third quarter of 2025 compared to 42,993 ounces in the third quarter of 2024. The decrease in gold production was primarily driven by lower head grade, lower recovery and lower throughput compared to the third quarter of 2024. During the third quarter of 2025, the average gold head grade and recovery were 0.34 g/t and 58.6%, respectively, compared to 0.40 g/t and 61.4% in the third quarter of 2024. The lower head gold grade was primarily due to mining sequence and lower average grades encountered in these zones which was consistent with the average grades incorporated in the MTM PFS. Lower recoveries were primarily due to lower head grades milled.

Copper production was 13.4 million pounds in the third quarter of 2025 compared to 13.7 million pounds in the third quarter of 2024. The slight decrease in copper production was primarily due to lower mill throughput. During the third quarter of 2025, the average copper head grade and recovery were 0.16% and 75.6%, respectively, compared to 0.16% and 73.8% in the third quarter of 2024.

Gold production costs were $1,540 per ounce in the third quarter of 2025 compared to $1,138 per ounce in the third quarter of 2024. The increase was primarily due to lower gold ounces sold, and higher allocation of costs to gold production costs due to relative changes in the market price of gold and copper.

Copper production costs were $2.11 per pound in the third quarter of 2025 compared to $1.99 per pound in the third quarter of 2024. The increase was primarily due to lower pounds of copper sold.

Mount Milligan Q3 All-in sustaining costs on a by-product basis per ounceNG ($/oz)

All-in sustaining costs on a by-product basisNG were $1,461 per ounce in the third quarter of 2025 compared to $1,318 per ounce in the third quarter of 2024. The increase was primarily due to lower gold ounces sold, partially offset by lower sustaining capital expendituresNG. Lower sustaining capital expendituresNG in the third quarter of 2025 were primarily due to lower spending on mining equipment overhauls and water sourcing projects compared to the third quarter of 2024.

Nine months ended September 30, 2025 compared to September 30, 2024

Earnings from mine operations of $128.2 million were recognized in 2025 compared to $89.3 million in 2024. The increase was primarily due to higher average realized gold and copper prices and lower DDA, partially offset by higher production costs lower gold ounces sold, and lower copper pounds sold. Lower DDA was due to an increase in proven and probable reserves as a result of the life of mine extension.

Cash provided by mine operations of $160.7 million was recognized in 2025 compared to $99.3 million in 2024. The increase was primarily due to higher average realized gold and copper prices and a favorable working capital change, partially offset by higher production costs and lower gold ounces and copper pounds sold. The favorable working capital change in 2025 compared to 2024 was primarily related to the timing of vendor payments, including amounts due to Royal Gold.

Free cash flow from mine operationsNG of $114.8 million was recognized in 2025 compared to $53.3 million in 2024. The increase was primarily due to higher cash provided by mine operations as explained above.

During 2025, mining activities were carried out in phases 5, 6, 7 and 10 of the open pit. Total tonnes mined were 35.7 million tonnes in 2025 compared to 36.4 million tonnes mined in 2024. The slight decrease in tonnage was primarily due to lower equipment availability in early 2025 compared to 2024.

The process plant throughput was 15.3 million tonnes in 2025, averaging 56,157 tonnes per calendar day compared to 16.0 million tonnes in 2024, averaging 58,261 tonnes per calendar day. Lower throughput was due to more maintenance activities and harder than anticipated ore during 2025. A mill maintenance shutdown was executed in the first half of 2025 for liner replacement of both ball mills which typically occurs every 18 months and was last completed in 2023.

Gold production was 103,477 ounces in 2025 compared to 129,919 ounces in 2024. The decrease was primarily due to lower gold head grades, lower gold recoveries and lower throughput. During 2025, the average gold grade was 0.35 g/t and recoveries were 60.9% compared to 0.41 g/t and 63.8%, respectively, in 2024. The lower head gold grade was primarily due to mining sequence and lower average grades encountered in these zones which was consistent with the average grades incorporated in the MTM PFS. Lower recoveries were primarily due to lower head grades milled.

Total copper production was 37.4 million pounds in 2025 compared to 41.6 million pounds in 2024. The decrease in copper production is primarily attributed to lower copper head grades and throughput. During 2025, the average copper head grade was 0.15% and recoveries were 76.7% compared to 0.17% and 75.6%, respectively, in 2024. The lower copper head grade was primarily due to mining sequence and lower average grades encountered in these zones as well as a higher proportion of stockpile material being reclaimed and processed through the mill for blending purposes.

Gold production costs were $1,423 per ounce in 2025 compared to $1,062 per ounce in 2024. The increase was primarily due to lower gold ounces sold and higher allocation of costs to gold production costs due to relative changes in the market price of gold and copper. Mining costs were higher due to timing of equipment overhaul and repairs, and RC drilling activities to improve geological and mine plan confidence. Processing costs were higher due to a planned mill maintenance shutdown in the first half of 2025, including the replacement of both ball and SAG mill liners compared to the replacement of only SAG mill liners during the mill maintenance shutdown in the first half of 2024. The expanded mill shutdown typically occurs every 18 months and as a result, contractor charges and liner costs were higher in 2025 compared to 2024.

Copper production costs of $2.13 per pound in 2025 remain consistent with $2.09 per pound in 2024.

Mount Milligan YTD all-in sustaining costs on a by-product basis per ounceNG ($/oz)

All-in sustaining costs on a by-product basisNG were $1,298 per ounce for 2025 compared to $1,064 per ounce in 2024. The increase was primarily due to higher production costs per ounce and lower ounces of gold sold.

Third Quarter 2025 compared to Third Quarter 2024

Earnings from mine operations were $90.2 million in the third quarter of 2025 compared with $71.2 million in the third quarter of 2024. The increase was primarily due to higher average realized gold prices. The increase in earnings from mine operations was partially offset by higher production costs mainly attributable to higher royalty rates adopted in 2025.

Cash provided by mine operations was $139.4 million in the third quarter of 2025, compared to $97.3 million in the third quarter of 2024. The increase in cash provided in mine operations was primarily due to higher average realized gold prices and a favorable working capital movement due to a higher VAT refund. Partially offsetting the increase in cash provided by mine operations were slightly higher production costs and lower gold ounces sold.

Free cash flow from mine operationsNG was $133.6 million in the third quarter of 2025, compared to $86.8 million in the third quarter of 2024. The increase in free cash flow from mine operationsNG was primarily due to an increase in cash provided by mine operations as noted above and lower sustaining capital expendituresNG mainly driven by lower deferred stripping costs.

Mining activities in the third quarter of 2025 were carried out in phase 5 and phase 6 of the Keltepe pit and in phase 2 of the Güneytepe pit. Total tonnes mined were 4.9 million tonnes in the third quarter of 2025 consistent with 4.9 million tonnes in the third quarter of 2024.

The Öksüt Mine stacked 1.5 million tonnes at an average grade of 1.82 g/t, containing 86,422 ounces of gold in the third quarter of 2025, compared to 1.5 million tonnes stacked at an average grade of 1.05 g/t, containing 48,928 ounces of gold in the third quarter of 2024. The increase in heap leach grade was primarily due to higher mining grades in the third quarter of 2025 as a result of mining higher grade areas in phase 5 and the bottom of the Keltepe pit.

Gold production in the third quarter of 2025 was 49,234 ounces compared to 50,719 ounces in the third quarter of 2024. The slight decrease in gold production was primarily due to higher gold inventory build-up at the ADR circuit and the heap leach facility in the third quarter of 2025.

Gold production costs per ounce were $1,219 in the third quarter of 2025 compared to $829 in the third quarter of 2024. The increase was primarily due to lower costs allocated to deferred stripping and, higher production costs as a result of the net inflation impact in Türkiye between the periods, which increased labor and contractor costs and higher royalty costs. The royalty costs increased by $11.7 million between the periods with approximately $5.4 million of this increase attributed to the elevated gold prices and approximately $6.3 million the result of updated royalty rates as described in the Recent Events section of this MD&A. Due to the fact that the change in royalty rates was retrospective to the beginning of 2025, the Company recognized the full adjustment to true up royalty costs for the year in the third quarter of 2025.

Öksüt Mine Q3 All-in sustaining costs on a by-product basis per ounceNG ($/oz)

All-in sustaining costs on a by-product basisNG in the third quarter of 2025 were $1,473 per ounce compared to $1,092 per ounce in the third quarter of 2024. The increase was primarily due to the higher production costs, and royalty costs per ounce as noted above, partially offset by lower sustaining capital expendituresNG mainly driven by lower deferred stripping costs.

Nine months ended September 30, 2025 compared to September 30, 2024

Earnings from mine operations were $172.2 million in 2025 compared with $215.2 million in 2024. The decrease was primarily due to lower ounces of gold produced and sold mainly attributable to higher production level in 2024 from processing the built-up heap leach inventory following the resumption of operations in June 2023. This decrease was partially offset by higher average realized gold prices.

Cash provided by mine operations was $172.2 million in 2025 compared with $196.6 million in 2024. The decrease in cash provided by mine operations was primarily due to lower ounces of gold sold, higher production costs and higher royalty payments. The decrease was partially offset by higher average realized gold prices, lower tax payments and a favorable working capital movement due to higher VAT refund and timing of vendor payments.

Free cash flow from mine operationsNG was $147.1 million in 2025 compared with $166.0 million in 2024. The decrease in free cash flow from mine operationsNG was due to decrease in cash provided by mine operations, partially offset by lower sustaining capital expendituresNG mainly from lower deferred stripping costs.

Mining activities in 2025 were carried out in phase 5 and phase 6 of the Keltepe pit and in phase 2 of the Güneytepe pit. Total tonnes mined were 12.7 million tonnes in 2025 and relatively consistent with 12.5 million tonnes in 2024.

The Öksüt Mine stacked 3.7 million tonnes at an average grade of 1.22 g/t containing 145,552 ounces of gold in 2025, compared with 3.5 million tonnes stacked at an average grade of 1.18 g/t containing 131,630 ounces of gold in 2024. The increase in stacked tonnes was primarily due to higher ore tonnes mined and the increase in heap leach grades was primarily due to higher mining grades in 2025 as a result of mining higher grade areas in phase 5 and the bottom of the Keltepe pit.

Gold production was 100,986 ounces in 2025 compared to 164,961 ounces in 2024, primarily due to higher production levels in 2024 from processing the built-up heap leach inventory following the resumption of operations in June 2023.

Gold production costs were $1,199 per ounce in 2025 compared with $710 per ounce in 2024. The increase was primarily due to lower gold ounces sold, higher production costs and higher royalty costs. Higher production costs were mainly due to lower costs allocated to deferred stripping, and higher weighted average cost per ounce in inventory as a result of net inflation impact in Türkiye between the periods, which increased

labour and contractor costs. The royalty costs increased by $2.2 million between the periods attributable to elevated gold prices and updated royalty rates as described in the Recent Events section of this MD&A.

All-in sustaining costs on a by-product basisNG were $1,573 per ounce in 2025 compared with $946 per ounce in 2024. The increase was primarily due to the higher production costs per ounce and higher royalty cost per ounce as noted above and lower ounces of gold sold.

Third Quarter 2025 compared to Third Quarter 2024

In the third quarter of 2025, the additions to property, plant and equipment were $36.2 million compared to $25.2 million in the third quarter of 2024 and non-sustaining capital expendituresNG were $31.4 million in the third quarter of 2025 compared to $25.2 million in the third quarter of 2024. The difference between additions to property, plant and equipment and non-sustaining capital expendituresNG in the third quarter of 2025 primarily reflects movements in the asset retirement obligation. The increase was due to the higher capital spending on mill detailed engineering, mining equipment refurbishments, construction of housing units, expenditures related to pre-stripping activities in the main open pit area and other general costs during the third quarter of 2025.

Nil cash used in operations and free cash flow deficit from operationsNG of $37.3 million were recognized in the third quarter of 2025, compared to cash used in operations of $2.2 million and free cash flow deficit from operationsNG of $32.4 million in the third quarter of 2024. The increase in free cash flow deficit from operationsNG was due to higher capital expendituresNG as outlined above.

In the third quarter of 2025, Thompson Creek Mine moved 8.3 million tons of waste compared to 3.3 million tons of waste in the third quarter of 2024. In the third quarter of 2025, the mining rate increased to an average of 2.8 million tons per month and mining activities focused on stripping in the Union Gap area and western side of the pit. In the third quarter of 2025, the equipment refurbishment scope of work was primarily focused on scheduled preventive maintenance of shovels. In the fourth quarter of 2025, activities will be focused on completing remaining refurbishment work, implementing preventive maintenance programs, optimizing mine and dump plans, and advancing site planning and design initiatives.

During the third quarter of 2025, plant refurbishment, detailed engineering, long lead procurement activities, demolition work, and housing development continued as planned. By the end of the third quarter of 2025, mill engineering was substantially completed, all major planned self-performed scopes of work were completed, including painting of thickener and flotation areas, the demolition of combined ball mill sump, crusher compressor installation as well as the re-installation of draw hole liners and apron feeders. In the fourth quarter of 2025, activities will be focused on the demolition of the pyrite circuit stairs, stripping and painting works, and general cleanup activities within the mill.

The long lead procurement activities progressed and by the end of the third quarter of 2025, all long lead packages and half of the total procurement packages have been awarded. The Company has also accelerated the timing of hiring of critical operational roles to de-risk start-up timeline.

In the third quarter of 2025, Thompson Creek Mine continued its effort in recruitment. Most of the key operations management positions have been filled and approximately 91% of the workforce was hired locally or from within the state of Idaho. Efforts continue to hire and onboard key support positions in the coming months. Construction of the housing lots progressed well during the quarter with some units made available for occupation or substantially complete. Site infrastructure development, including local housing capacity, is

underway with work expected to be completed by the end of 2025 to support the long-term needs of the Thompson Creek Mine.

Nine months ended September 30, 2025 compared to September 30, 2024

The additions to property, plant and equipment were $94.8 million in 2025 compared to $30.8 million in 2024 and non-sustaining capital expendituresNG were $83.7 million in 2025 compared to $30.8 million in 2024. The difference between additions to property, plant and equipment and non-sustaining capital expendituresNG in 2025 primarily reflects movements in the asset retirement obligation. The increase was due to higher capital spending on mining equipment refurbishment and purchases, mill detailed engineering work, construction of housing units, expenditures related to pre-stripping activities in the main open pit area and other general costs in 2025.

Nil cash used in operations and free cash flow deficit from operationsNG of $90.6 million in 2025 compared to cash used in operations of $16.5 million and free cash flow deficit from operationsNG of $48.7 million in 2024. The increase in free cash flow deficit from operationsNG was due to higher additions to PP&E as outlined above.

(2)Amount does not include 2.7 million pounds of molybdenum roasted of toll material for the three months ended and 2.9 million pounds for the nine months ended September 30, 2025 (1.5 million pounds for three and nine months ended September 30, 2024).

Third Quarter 2025 compared to Third Quarter 2024

The Langeloth Facility roasted 4.4 million pounds and sold 3.1 million pounds of molybdenum in the third quarter of 2025, compared to 2.4 million pounds roasted and 2.4 million pounds sold in the third quarter of 2024. The increase in molybdenum roasted and sold in the third quarter of 2025, compared to the third quarter of 2024, was primarily due to strong demand from its main contract customers during the third quarter of 2025 and slightly slower ramp up of molybdenum production following the planned acid plant shut down executed in the second quarter of 2024. The increased volumes in 2025 are in line with the Company’s

strategy to progressively ramp-up volumes at the Langeloth facility over time, including a goal to increase roasting volumes to the range of 13 to 15 million pounds in 2025.

Loss from operations was $0.2 million in the third quarter of 2025 compared to $2.0 million in the third quarter of 2024. The decrease in loss from operations was primarily due to the increase in the pounds of molybdenum sold during the third quarter of 2025 compared to the third quarter of 2024, higher revenue from by-products and higher tolling volumes, partially offset by higher plant operating costs from increased consumables and ingredients in the third quarter of 2025.

Adjusted EBITDANG of $1.1 million was recognized in the third quarter of 2025 compared to a negative adjusted EBITDANG of $1.2 million recognized in the third quarter of 2024. The increase in adjusted EBITDANG was primarily due to the decrease in loss from operations as discussed above. The financial results at the Langeloth Facility were not significantly impacted by the tariffs during the third quarter of 2025.

Cash used in operations was $13.6 million in the third quarter of 2025 compared to $7.3 million in the third quarter of 2024. The increase in cash used in operations was primarily due to an unfavourable working capital movement due to an inventory build-up and higher average market molybdenum prices in the third quarter of 2025. The inventory build-up is part of the planned capacity ramp-up.

Free cash flow deficit from operationsNG was $13.9 million in the third quarter of 2025 compared to $8.6 million in the third quarter of 2024. The increase in free cash flow deficit from operationsNG is primarily due to the increase in cash used in operations in the third quarter of 2025 as discussed above.

Molybdenum prices increased during the quarter, with a monthly average increased from $23.08 per pound to a monthly average of $25.40 per pound. At September 30, 2025, there were 1.8 million (December 31, 2024 - 1.3 million) pounds of purchased molybdenum outstanding under contracts awaiting final settlement in the subsequent quarter. All of the purchased molybdenum was adjusted to a fair value price of approximately $23.29 (December 31, 2024 - $20.09) per pound at the end of the quarter. Molybdenum in concentrate is purchased at a discount to market molybdenum prices.

(1) The graph presents monthly average molybdenum prices.

Nine months ended September 30, 2025 compared to September 30, 2024

The Langeloth Facility roasted 10.6 million pounds and sold 10.4 million pounds of molybdenum in 2025 compared to 7.3 million pounds roasted and 8.1 million pounds sold in 2024. The increase in the molybdenum roasted and sold was primarily due to strong demand from its main contract customers in 2025 and a planned acid plant shut down in 2024.

Loss from operations was $2.1 million in 2025 compared to $6.9 million in 2024. The decrease in loss from operations was primarily due to higher pounds of molybdenum roasted and sold and higher revenue from by-products and tolling volumes in 2025, partially offset by higher plant costs from increased consumables and ingredients in 2025.

Adjusted EBITDANG of $1.4 million was recognized in 2025 compared to a negative adjusted EBITDANG of $4.5 million in 2024. The increase in adjusted EBITDANG was primarily due to the decrease in loss from operations as discussed above.

Cash used in operations was $15.2 million in 2025 compared to $5.6 million in 2024. The increase in cash used in operations was primarily due to an unfavourable working capital movement due to an inventory build-up at higher average market molybdenum prices in 2025 compared to a favourable working capital movement from cash collection and vendor payments in 2024. The inventory build-up is part of the planned capacity ramp-up.

Free cash flow deficit from operationsNG was $16.1 million in 2025 compared to $10.5 million in 2024. The increase in free cash flow deficit from operationsNG was primarily due to higher cash used in operations as outlined above, partially offset by higher additions to PP&E related to planned maintenance of the acid plant in 2024.

Endako Mine

Third Quarter 2025 compared to Third Quarter 2024

Earnings from operations of $1.6 million were recognized at the Endako Mine in the third quarter of 2025 compared to loss from operations of $4.8 million in the third quarter of 2024. The increase in earnings from operations was primarily due to a higher reclamation recovery recognized in the third quarter of 2025 resulting from an increase in the risk-free interest rates applied to discount the provision for future reclamation cash outflows at the Endako Mine in the third quarter of 2025.

In the third quarter of 2025, cash used in operations and free cash flow deficit from operationsNG at the Endako Mine were both $2.7 million compared to $4.4 million in the third quarter of 2024. The decrease in cash used in operations and the free cash flow deficitNG were primarily due to lower reclamation payments related to the construction of the spillway for the closure of the Tailings Pond 2. Both Tailings Pond 2 spillway and the Denak West dewatering projects are in their final stages of completion and work is expected to be finalized early in the fourth quarter of 2025.

Nine months ended September 30, 2025 compared to September 30, 2024

Loss from operations of $3.9 million was recognized in 2025 compared to loss from operations of $4.0 million in 2024. The decrease in loss from operations was primarily attributable to a higher reclamation recovery in 2025 resulting from changes in the discount rates applied to the estimate of future reclamation cash flows.

Cash used in operations and free cash flow deficit from operationsNG was $8.1 million in 2025 compared to $6.5 million in 2024. The increase in cash used in operations was due to more reclamation activities related to the closure of the spillway for Tailings Pond 2 and the Denak West dewatering projects.

Net earnings (loss) have fluctuated since the third quarter of 2023 due to a variety of factors ranging from impairment losses (reversals) to reclamation expense (recovery) and unrealized losses and gains on financial instruments.

The net earnings in the third quarter of 2025 benefited from higher gold and copper prices, along with a non-cash impairment reversal at the Goldfield Project, non-cash gain on the sale of the Company’s interest in the Greenstone Gold Mines Partnership and unrealized gain relating to the Additional Royal Gold Agreement, partially offset by lower gold ounces and copper pounds sold. The net loss in the fourth quarter of 2024 was negatively impacted by the non-cash impairment loss at the Goldfield Project. The net loss in the fourth quarter of 2023 was negatively impacted by the non-cash impairment loss at the Kemess Project.

Accounting Estimates, Policies and Changes

Accounting Estimates

The preparation of the Company’s consolidated financial statements in accordance with IFRS requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. The critical estimates and judgments applied in the preparation of the Company’s unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2025 are consistent with those used in the Company’s consolidated financial statements for the year ended December 31, 2024, with the exception of those disclosed in note 3 of the unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2025.

Management’s estimates and underlying assumptions are reviewed on an ongoing basis. Any changes or revisions to estimates and underlying assumptions are recognized in the period in which the estimates are revised and in any future periods affected. Changes to these critical accounting estimates could have a material impact on the consolidated financial statements.

The key sources of estimation uncertainty and judgment used in the preparation of the consolidated financial statements that might have a significant risk of causing a material adjustment to the carrying value of assets and liabilities and earnings are outlined in note 4 of the consolidated financial statements for the year ended December 31, 2024 with the exception of those disclosed in note 3 of the unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2025.

Accounting Policies and Changes

The accounting policies applied in the unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2025 is consistent with those used in the company’s consolidated financial statements for the year ended December 31, 2024.

Disclosure Controls and Procedures and Internal Control Over Financial Reporting

Pursuant to regulations adopted by the U.S. Securities and Exchange Commission, under the U.S. Sarbanes-Oxley Act of 2002 (“SOX”) and those of the Canadian Securities Administrators, the Company’s management evaluates the effectiveness of the design and operation of the Company's disclosure controls and procedures, and internal control over financial reporting. This evaluation is done under the supervision of, and with the participation of, the Chief Executive Officer and the Chief Financial Officer.

For the quarter ended September 30, 2025, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures, and internal control over financial reporting are designed to provide reasonable assurance regarding the reliability of information disclosed in its filings, including its interim financial statements prepared in accordance with IFRS. In making this assessment, management used the criteria specified in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

There has been no change in the Company’s internal control over financial reporting during the three and nine months ended September 30, 2025, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company’s management, including the Chief Executive Officer and the Chief Financial Officer, believes that any disclosure controls and procedures and internal control over financial reporting, no matter how well designed and operated, can have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance that the objectives of the control system are met.

Non-GAAP and Other Financial Measures

This MD&A 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.

Definitions

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

•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 September 30, 2025, 727 and 667 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.

•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.

•Average realized molybdenum price is a supplementary financial measure calculated by dividing the different components of molybdenum sales (including third party sales, mark-to-market adjustments and final pricing adjustments) by the number of pounds sold. Management uses this measure to monitor its sales of molybdenum pounds against the average market molybdenum 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.

Certain unit costs, including all-in sustaining costs on a by-product basis (including and excluding revenue-based taxes) per ounce, are non-GAAP ratios which include as a component certain non-GAAP financial measures including all-in sustaining costs on a by-product basis which can be reconciled as follows:
