2. Basis of preparation

(a)  Statement of compliance:

These interim financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB") and do not include all of the information required for annual financial statements prepared in accordance with IFRS® Accounting Standards as issued by the IASB.

These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2024 which includes information necessary or useful to understanding the Company's business and financial statement presentation. In particular, the Company's material accounting policies are presented in note 3 in the Company's audited consolidated financial statements for the year ended December 31, 2024 and have been consistently applied in the preparation of these interim financial statements, except as noted below.

Impairment of non-financial assets

The Company will perform the Copper Mountain goodwill impairment test on an annual basis as at July 1 each year to better align with the timing of the annual long-range planning process. This represents a change in accounting policy regarding the timing of the annual goodwill impairment test which was previously performed December 31. All other material accounting policies related to the impairment of non-financial assets remain consistent as presented in Note 3 of the Company's audited consolidated financial statements for the year ended December 31, 2024.

As a result of the acquisition of Mitsubishi Materials Corporation's ("MMC") 25% interest in CMBC on April 30, 2025, the Company's interim financial statements also reflect the following relevant accounting policies.

Contingent Payments from the purchase of non-controlling interest outside the scope of Business Combination

Contingent payments arising from the purchase of non-controlling interest are initially recognized as a financial liability at their fair value on the date the obligation arises. The fair value is determined by discounting the payments to its present value using a company credit adjusted discount rate that reflects current market assessments of the time value of money and the risks specific to the company. The contingent consideration will be classified as a financial liability at amortized cost, with subsequent remeasurements recognized in profit or loss. Additionally, the liability will then be accreted and amortized until the maturity date, with the accretion expense flowing through profit or loss (note 4).

The Board of Directors approved these interim financial statements on August 12, 2025.

(b)  Use of judgements and estimates:

The preparation of the interim financial statements in conformity with IFRS® Accounting Standards requires Hudbay to make judgements, estimates and assumptions, in applying accounting policies that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements, as well as reported amounts of revenue and expenses during the reporting period. Actual results may differ from these judgements, estimates and assumptions. The interim financial statements reflect the judgements and estimates outlined by Hudbay in its audited consolidated financial statements for the year ended December 31, 2024.

3. New standards

New standards issued but not yet effective

(a) IFRS 18 - Presentation and Disclosure in Financial Statements

In April 2024, the IASB released IFRS 18 Presentation and Disclosure in Financial Statements. IFRS 18 will replace IAS 1 Presentation of Financial Statements. The standard amends the presentation of the statement of income by introducing a newly defined 'operating profit' subtotal and a requirement for income and expenses to be allocated between three new distinct categories based on a company's main business activities, which are Operating, Financing and Investing. In addition, organizations will need to disclose certain 'non-GAAP' measures known as management-defined performance measures. The standard will be effective from January 1, 2027 with early adoption permitted and requires retrospective application. The Company is assessing the impact of adoption of this amendment on its consolidated financial statements.

(b) Amendments to IFRS 9 - Financial Instruments and IFRS 7 - Financial Instruments: Disclosures

In May 2024, the IASB issued amendments to IFRS 9 and 7 to clarify the recognition or derecognition of a financial asset or liability, with a new exception for some financial liabilities settled through an electronic cash transfer system. The amendments also add guidance for assessing whether a financial asset meets the solely payments of principal and interest (SPPI) criterion, by introducing an additional SPPI test for financial assets with contingent features that are not related directly to a change in basic lending risks or costs. In addition, the amendments will add new disclosures for certain instruments with contractual terms that can change cash flows. Lastly, the amendments will require additional disclosures for equity instruments designated at fair value through other comprehensive income. The amendments will apply for reporting periods beginning on or after January 1, 2026, with early application permitted. The Company is assessing the impact of adoption of this amendment on its consolidated financial statements.

In December 2024, the IASB issued amendments to IFRS 9 and 7 to clarify the application of the 'own-use' exemption and provide guidance on hedge accounting for companies that hedge their purchase or sales of electricity using renewable power purchase agreements. The amendments also introduce new disclosure requirements. The amendments will apply for reporting periods beginning on or after January 1, 2026, with early application permitted. The Company is assessing the impact of adoption of this amendment on its consolidated financial statements.

4. Copper Mountain non-controlling interest acquisition

On April 30, 2025, Hudbay completed the acquisition of MMC's 25% interest in CMBC (the "Transaction"). The cash consideration of the Transaction consisted of:

• $4.5 million on closing date of the Transaction,

• $21.0 million in seven annual deferred payments of $3.0 million each, commencing on the 12-month anniversary of the closing date of the Transaction, and

• up to $18.75 million in five additional contingent payments of $3.75 million each, payable in the years following New Ingerbelle achieving certain minimum annual operating thresholds. MMC's right to the contingent payments concludes on the 15-year anniversary of the closing date of the Transaction.

As a result of the Transaction, Hudbay increased its ownership of the Copper Mountain mine from 75% to 100%.

The company recorded $35.9 million of total consideration for the Transaction which included the cash payment of $4.5 million on the closing date, $16.6 million of deferred payments and $13.3 million of contingent consideration recorded as financial liability at amortized cost (note 13) and $1.5 million of transaction costs recorded within equity. 

As a result of the Transaction, the Company recorded an increase to equity as follows:

There were no substantive changes to the Company's ownership in CMBC during the year ended December 31, 2024.

5. Revenue and expenses

(a) Revenue

Hudbay's revenue by significant product types:

Consideration from the Company's stream agreements is considered variable (note 16). Gold and silver stream revenue can be subject to cumulative adjustments when the amount of precious metals to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2025, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a variable consideration adjustment was made for all prior year stream revenues since the stream agreement inception date. This variable consideration adjustment for the six months ended June 30, 2025 resulted in an increase in revenue of $9.9 million (six months ended June 30, 2024 - decrease in revenue of $3.8 million).

(b) Depreciation and amortization

Depreciation of property, plant and equipment and amortization of intangible assets are reflected in the condensed consolidated interim statements of income as follows:

      (c)  Other expenses

During the second quarter of 2025, the Manitoba business unit incurred costs related to emergency and evacuation activities of $2.1 million as a result of regional wildfires in Snow Lake, Flin Flon and surrounding areas. 

The Flin Flon concentrator and tailings impoundment is on care and maintenance to provide optionality should another mineral discovery occur in the Flin Flon area. During the three and six months ended June 30, 2025, care & maintenance costs were $2.9 million and $6.3 million, respectively (three and six months ended June 30, 2024 - $3.7 million and $6.8 million, respectively).

The Arizona business unit held an option to acquire water rights and land, which expired during the first quarter of 2024 without being extended or exercised. The previously capitalized cost to maintain the option, net of accrued interest, of $8.1 million is presented as part of write-down of PP&E.

  (d)  Net finance expense

Other finance expense relates primarily to standby fees on Hudbay's revolving credit facilities.

Commencing in the first quarter of 2024, Hudbay has entered into copper forward sales, copper costless collars and gold costless collars which are non-quotational pricing ("non-QP") contracts (note 21b). Subsequent movements in the fair value of non-QP contracts are recognized in change in fair value of financial instruments in the condensed consolidated interim statements of income. As of June 30, 2025, there are no non-QP hedges outstanding.

During the third quarter of 2024, the Company completed the final delivery and settled the obligation for the gold prepayment liability.

  (e)  Share-based compensation expense

Share-based compensation expense included within cost of sales, selling and administrative expenses, and other expenses relates to deferred share units, restricted share units, performance shares units and the Company's stock option plan. The increase in share-based compensation expense during the three and six months ended June 30, 2025 compared with the same periods last year primarily relates to the change in the Company's share price, partially offset by adjustments to the performance based multiplier on certain share units.

6. Short-term investments

Short-term investments include guaranteed investment certificates held with Canadian financial institutions. The Company currently holds nil guaranteed investment certificates. As at December 31, 2024, the Company held two $20.0 million guaranteed investment certificates that matured in March 2025 and June 2025, respectively.

7. Trade and other receivables

8. Inventories

The cost of inventories recognized as an expense, including depreciation, and included in cost of sales amounted to $313.9 million and $630.3 million, respectively, for the three and six months ended June 30, 2025 (three and six months ended June 30, 2024 - $311.7 million and $640.2 million, respectively).

During the three and six months ended June 30, 2025, Hudbay recognized an expense of $1.1 million and $1.5 million, respectively, in cost of sales primarily related to adjustments of the carrying value of copper concentrate inventory to net realizable value (three and six months ended June 30, 2024 - nil).

During the three and six months ended June 30, 2025, Hudbay recognized an expense of $2.4 million and $3.3 million, respectively, in cost of sales related to the write-off of provision on certain non-current inventory supplies.

9. Other financial assets

Investments at fair value through profit or loss increased to $39.3 million as at June 30, 2025, from $12.1 million as at December 31, 2024. The increase primarily relates to the acquisition of 11,852,064 common shares of Arizona Sonoran in January 2025 at a price of C$1.68 per share, for a total investment of $13.8 million. The remainder of the movement is primarily attributable to mark-to-market adjustments recognized during the period.

10. Intangibles and other assets

Intangibles and other assets of $50.7 million (December 31, 2024 - $44.3 million) includes $43.4 million of other assets (December 31, 2024 - $38.8 million) and $7.3 million of intangibles (December 31, 2024 - $5.5 million).

Other assets represent the carrying value of certain future community costs that relate to original agreements with communities for the Constancia operation which allow Hudbay to extract minerals over the useful life of the Peru operation. The liability remaining for these costs is recorded in agreements with communities recorded at amortized cost (note 13). Amortization of the carrying amount is recorded in the condensed consolidated interim statements of income within other expenses (note 5c) or exploration expenses, depending on the nature of the agreement.

Intangibles mainly represent computer software costs.

11. Property, plant and equipment

During the first quarter of 2024, Hudbay received a grant of $2.4 million from the Environment and Climate Change Canada related to the purchase of an electric mining shovel in the third quarter of 2023. The carrying amount of the shovel has been deducted by the amount of the grant received. The grant will be recognized in profit or loss over the life of the shovel as a reduced depreciation expense. There were no significant unfulfilled conditions attached to the grant.

12. Other liabilities

13. Other financial liabilities

Equipment financing represents agreements that Hudbay has entered into to purchase mining equipment. Hudbay owns the assets and finances the payment of these assets over the specified term. These agreements expire between 2025 and 2032 with interest rates between 2.25% and 7.55% per annum. During the six months ended June 30, 2025, $8.2 million (December 31, 2024 - $71.0 million) of capital additions related to the recognition of property, plant and equipment that has been financed (note 23). 

Agreements with communities recorded at amortized cost relate to agreements with communities near the Constancia operation which allow Hudbay to extract minerals over the useful life of the Constancia operation, carry out exploration and evaluation activities in the area and provide Hudbay with community support to operate in the region. During the six months ended June 30, 2025, Hudbay entered into two additional two-year community agreements, resulting in net additions of $9.9 million related to agreements with communities.

As part of the acquisition of remaining 25% interest in CMBC (note 4), the Company recorded $16.6 million of deferred payment consideration and $13.3 million of contingent consideration as a financial liability at amortized cost on the closing of the transaction. During the three and six months ended June 30, 2025, accretion related to these liabilities were $0.3 million (note 5d).

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the stream deposit by August 1, 2052, the expiry date of the agreement. If the stream deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a payment for the remaining amount will be due at the expiry date of the agreement. As the 777 mine has concluded all mining activities following the depletion of reserves and finalized the sales of produced concentrate, Hudbay concluded that the remaining stream deposit will not be repaid by means of precious metals credits from 777 production. The repayment amount is recorded as a Wheaton refund liability, which is and will be discounted at the 9.0% rate inherent in the original 777 stream agreement and accreted over the remaining term of the agreement.

14. Lease liabilities

Lease liabilities are reflected in the condensed consolidated interim balance sheets as follows:

Hudbay has entered into leases which expire between 2025 and 2037. The interest rates on leases which were capitalized have interest rates between 2.50% and 8.49%, per annum. The range of interest rates utilized for discounting the lease depends mostly on Hudbay acting as a lessee and duration of the lease. For certain leases, Hudbay has the option to purchase the equipment and vehicles leased at the end of the terms of the leases. Hudbay's obligations under these leases are secured by the lessor's title to the leased assets. The present value of applicable lease payments has been recognized as an ROU asset, which was included as a non-cash addition to property, plant and equipment, and a corresponding amount as a lease liability.

There are no restrictions placed on Hudbay by entering into these leases.

The following outlines expenses recognized within the Company's condensed consolidated interim statements of income, relating to leases for which a recognition exemption was applied.

Payments made for short-term, low value and variable leases would mostly be captured as expenses in the condensed consolidated interim statements of income, however, certain amounts may be capitalized to PP&E for the Arizona segment during its development phase and certain amounts may be reported in inventories given the timing of sales. Variable payment leases include equipment used for heavy civil works at Constancia.

15. Long-term debt

(a) Senior unsecured notes

As at June 30, 2025, $1,067.4 million aggregate principal amount of senior notes were outstanding in two series: (i) a series of 4.50% senior notes due April 2026 ("2026 notes") in an aggregate principal amount of $525.0 million and (ii) a series of 6.125% senior notes due April 2029 ("2029 notes") in an aggregate principal amount of $542.4 million. During the second quarter of 2025, the Company repurchased and retired $50.0 million of the 2026 notes. To date, the Company repurchased and retired a total of $75.0 million of the 2026 notes and $57.6 million of the 2029 notes at a discount. For the six months ended June 30, 2025, the discount of $0.3 million (December 31, 2024 - $0.7 million) was recorded as Other expenses in the condensed consolidated interim statements of income.

Upon the repurchase and retirement of the additional $50.0 million of senior unsecured notes in the second quarter of 2025, the unamortized transaction costs related to this principal amount were recorded as a finance expense in the condensed consolidated interim statements of income.

The senior notes are guaranteed on a senior unsecured basis by substantially all of the Company's subsidiaries, other than HudBay (BVI) Inc. and certain excluded or unrestricted subsidiaries, and subsidiaries that hold the Copper World and Mason projects as well as any newly formed or acquired subsidiaries that primarily hold or may develop non-producing mineral assets that are in the pre-construction phase of development.

(b) Senior secured revolving credit facilities

Hudbay has two senior secured revolving credit facilities with total commitments of $450.0 million and substantially similar terms and conditions for its Canadian and Peruvian businesses. Hudbay's revolving credit facilities are secured against substantially all of the Company's assets, other than those associated with the Copper Mountain mine and the Copper World and Mason projects. During 2024, Hudbay repaid $10.0 million under its Canadian revolving credit facility and $90.0 million under the Peruvian revolving credit facility. During the fourth quarter of 2024, the two senior secured revolving credit facilities were extended by three years from October 2025 to November 2028. The newly extended $450.0 million revolving credit facility includes an accordion feature to increase the facility by an additional $150 million at Hudbay's discretion during the four-year tenor. Hudbay incurred $2.4 million of transactions costs associated with the extension which were deferred and amortized over the new term of the credit facilities.

As at June 30, 2025, there were nil draws under the Canadian and Peruvian revolving credit facilities, other than letters of credit to support reclamation and pension obligations as described below.

As at June 30, 2025, the Peru segment had nil in letters of credit issued under the Peru revolving credit facility to support its reclamation obligations and the Manitoba segment had $25.3 million in letters of credit issued under the Canadian revolving credit facility to support its reclamation and pension obligations. As at June 30, 2025, we were in compliance with our covenants under the revolving credit facilities.

Surety bonds

The Arizona segment had $18.4 million in surety bonds issued to support future reclamation and closure obligations. No cash collateral is required to be posted under these surety bonds.

The British Columbia segment had $48.1 million in surety bonds issued to support future reclamation and closure obligations. The British Columbia segment had $1.0 million in surety bonds issued to BC Hydro in relation to the BC Hydro transmission system at the Copper Mountain Mine, and to Fisheries and Oceans Canada for fish monitoring. No cash collateral is required to be posted under these surety bonds.

The Peru segment had $23.3 million in surety bonds issued to support future reclamation and closure obligations. No cash collateral is required to be posted under these surety bonds.

Other letters of credit

The Peru segment had $111.7 million in letters of credit issued with various Peruvian financial institutions to support future reclamation and other operating matters. No cash collateral is required to be posted under these letters of credit.

Hudbay has a C$130.0 million bilateral letter of credit facility ("LC Facility") with a major Canadian financial institution. As at June 30, 2025, the Manitoba segment had $56.7 million in letters of credit issued under the LC Facility to support its reclamation and pension obligations.

16. Deferred revenue

Peru Stream Agreement

For the three and six months ended June 30, 2025, the drawdown rates for the Peru stream agreement for gold and silver were $860 and $15.06 per ounce, respectively (year ended December 31, 2024 - $817 and $14.56 per ounce, respectively).

The following table summarizes changes in deferred revenue:

Consideration from the Company's stream agreement is considered variable. Gold and silver stream revenue can be subject to cumulative adjustments when the number of ounces to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2025, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a current period variable adjustment was made for all prior period stream revenues since the stream agreement inception date. This variable consideration adjustment resulted in an increase in revenue of $9.9 million and a decrease of finance expense of $0.6 million for the six months ended June 30, 2025 (year ended December 31, 2024 - decrease in revenue of $3.8 million and an increase of finance expense of $0.2 million).

Deferred revenue is reflected in the condensed consolidated interim balance sheets as follows:

17. Environmental and other provisions

Reflected in the condensed consolidated interim balance sheets as follows:

Decommissioning and restoration obligations ("DRO") are remeasured at each reporting date to reflect changes in discount rates, exchange rates, and timing and extent of cash outflows which can significantly affect the liabilities. This provision has been recorded based on estimates and assumptions that management believes are reasonable; however, actual decommissioning and restoration costs may differ from expectations.

During the six months ended June 30, 2025, the Company recorded a non-cash gain of $1.0 million in the condensed consolidated interim statements of income mainly related to a revaluation adjustment to the Flin Flon environmental reclamation provision. The re-evaluation adjustment was impacted by an increase in long term, risk-free real discount rates based on changes in Canadian bond yields. Typically, an operating location will reflect any revaluation adjustments to the environmental reclamation provision against its reclamation assets. However, as the Flin Flon operations closed in June 2022, the corresponding Flin Flon assets have been fully depreciated and cannot be reduced below residual value resulting in the remaining impact being recorded as a loss in the condensed consolidated interim statements of income.

As at June 30, 2025, decommissioning, restoration and similar liabilities have been discounted to their present value at rates ranging from 2.61% to 4.89% per annum (December 31, 2024 - 2.87% to 4.88%), using pre-tax, nominal risk-free interest rates that reflect the estimated maturity of each specific liability.

During the six months ended June 30, 2024, the Company recorded a non-cash gain of $8.0 million in the condensed consolidated interim statements of income mainly related to a revaluation adjustment to the Flin Flon environmental reclamation provision.

18. Income and mining taxes

    The tax expense is applicable as follows:

Adjustments in respect of prior years refers to amounts changing due to the filing of tax returns and assessments from government authorities as well as any change identified that would result in a difference to our current or deferred tax balances as reported in the prior fiscal year end.

19. Share capital

(a) Preference shares:

Authorized: Unlimited preference shares without par value.

Issued and fully paid: Nil.

(b) Common shares:

Authorized: Unlimited common shares without par value.

During the six months ended June 30, 2025, the Company declared a dividend of C$0.01 per share. The Company paid $2.8 million in dividends on March 21, 2025 to shareholders of record as of March 4, 2025.

On June 24, 2025, the Company closed a private placement deal to issue 465,394 common shares at a price of C$13.30 per Common Share for aggregate gross proceeds of $4.5 million. Associated with the private placement were $0.3 million of share issuance costs resulting in net equity raised of $4.2 million. The net proceeds of this private placement were used to fund the $4.5 million cash consideration on closing of the acquisition of MMC's 25% interest in CMBC (note 4).

On May 24, 2024, the Company closed an equity financing with a syndicate of underwriters ("the Offering"). Pursuant to the Offering, the Underwriters purchased on a bought deal basis from the Company a total of 42,366,000 common shares at a price of $9.50 per Common Share for aggregate gross proceeds of $402.5 million. Transaction costs related to the Offering were $16.1 million resulting in net proceeds to the Company of $386.4 million. Associated with the Offering were $0.2 million of share issuance costs resulting in net equity raised of $386.2 million.

During the year ended December 31, 2024, the Company completed a Canadian Development Expense and Canadian Exploration Expense flow-through financing. The flow-through share liability was recognized in earnings as eligible expenditures were made. The Company issued 968,900 common shares for proceeds, net of transaction costs, of $11.8 million. The implied premium on the flow-through shares of $3.2 million was recorded as a flow-through share liability. At June 30, 2025, the Company has incurred $5.6 million in qualifying expenditures related to this flow-through financing. The flow-through share liability will be recognized in earnings as eligible expenditures are made.

During the year ended December 31, 2024, the Company declared two semi-annual dividends of C$0.01 per share. The Company paid $2.6 million and $2.9 million in dividends on March 22, 2024 and September 20, 2024 to shareholders of record as of March 5, 2024 and September 3, 2024.

(c) Equity-settled share-based compensation

Stock Options

The Company's stock option plan was approved in June 2005 and amended in May 2008 (the "Plan"). Under the amended Plan, the Company may grant to employees, officers, directors or consultants of the Company or its affiliates options to purchase up to a maximum of 13 million common shares of Hudbay. The Company has determined that the appropriate accounting treatment is to classify the stock options as equity settled transactions.

The following table outlines the changes in the number of stock options outstanding:

Hudbay estimates expected life of options and expected volatility based on historical data, which may differ from actual outcomes.

Warrants

The following table outlines the changes in the number of Hudbay warrants outstanding:

20. Earnings per share

The calculation of dilutive weighted-average number of common shares excludes the impact of 274,405 and 197,982 shares for the three and six months ended June 30, 2025 (three and six months ended June 30, 2024 - 58,344 and 79,912). The shares related to stock options and warrants were excluded as the exercise price related to the particular security exceeded the average market price of the Company's common shares for the period, or the inclusion of the share units had an anti-dilutive effect on net income.

21. Financial instruments

(a) Fair value and carrying value of financial instruments:

The following presents the fair value ("FV") and carrying value ("CV") of Hudbay's financial instruments and non-financial derivatives:

Fair value hierarchy

The table below provides an analysis by valuation method of financial instruments that are measured at fair value subsequent to recognition as well as financial instruments not measured at fair value but for which a fair value is disclosed. Levels 1 to 3 are defined based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value, as follows:

- Level 1: Quoted prices in active markets for identical assets or liabilities;

- Level 2: Valuation techniques use significant observable inputs, either directly or indirectly, or

                          valuations are based on quoted prices for similar instruments; and,

- Level 3: Valuation techniques use significant inputs that are not based on observable market

                  data.

The Company's policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. During the six months ended June 30, 2025 and year ended December 31, 2024, Hudbay did not make any such transfers.

Valuation techniques used for instruments categorized in Levels 2 and 3 are consistent with the year ended December 31, 2024.
