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 full 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.

The Board of Directors approved these interim financial statements on May 9, 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 is 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. Revenue and expenses

(a) Revenue

Hudbay's revenue by significant product types:

Three months ended March 31,
2025 2024
Copper $ 302.3 $ 285.2
Gold 194.2 178.1
Zinc 14.3 14.9
Silver 14.3 12.2
Molybdenum 20.9 18.2
Other (0.2 ) -
Revenue from contracts 545.8 508.6
Non-cash streaming arrangement items ^1^
Amortization of deferred revenue - gold 8.4 16.4
Amortization of deferred revenue - silver 11.0 10.6
Amortization of deferred revenue - variable consideration adjustments - prior periods 9.9 (3.8 )
29.3 23.2
Pricing and volume adjustments ^2^ 33.8 20.9
608.9 552.7
Treatment and refining charges (14.0 ) (27.7 )
$ 594.9 $ 525.0
^1^See note 15.
^2^Pricing and volume adjustments represent mark-to-market adjustments on initial estimate of provisionally priced sales, realized and unrealized changes to fair value of quotational pricing hedge derivative contracts and adjustments to originally invoiced weights and assays.

Consideration from the Company's stream agreements is considered variable (note 15). 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 three months ended March 31, 2025 resulted in an increase in revenue of $9.9 million (March 31, 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:

Three months ended March 31,
2025 2024
Cost of sales $ 108.1 $ 109.3
Selling and administrative expenses 0.4 0.5
$ 108.5 $ 109.8

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.

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 months ended March 31, 2025, care & maintenance costs were $3.4 million (three months ended March 31, 2024 - $3.1 million).

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 decrease in share-based compensation expense during the three months ended March 31, 2025 compared with the same period 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.

5. Short-term investments

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

Investments at fair value through profit or loss increased to $34.1 million as at March 31, 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 at a price of C$1.68 per share, for a total investment of $13.8 million. The remainder of the movement is attributable to mark-to-market adjustments recognized during the period.

9. Intangibles and other assets

Intangibles and other assets of $43.1 million (December 31, 2024 - $44.3 million) includes $36.7 million of other assets (December 31, 2024 - $38.8 million) and $6.4 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 12). Amortization of the carrying amount is recorded in the condensed consolidated interim statements of income within other expenses (note 4c) or exploration expenses, depending on the nature of the agreement.

Intangibles mainly represent computer software costs.

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.

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.

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 three months ended March 31, 2025, $4.8 million (December 31, 2024 - $71.0 million) of capital additions related to the recognition of property, plant and equipment that has been financed (note 22).

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.

Current $ 33.7 $ 30.5
Non-current 41.8 44.3
$ 75.5 $ 74.8

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.

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 March 31, 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 March 31, 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 $24.1 million in letters of credit issued under the Canadian revolving credit facility to support its reclamation and pension obligations. As at March 31, 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 $45.7 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 $42.5 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 $92.6 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.

The British Columbia segment had $0.6 million in letters of credit issued with various Canadian financial institutions related to other operating matters. Cash collateral deposit has been posted under these letters of credit (note 8).

Hudbay has a C$130.0 million bilateral letter of credit facility ("LC Facility") with a major Canadian financial institution. As at March 31, 2025, the Manitoba segment had $52.7 million in letters of credit issued under the LC Facility to support its reclamation and pension obligations.

15. Deferred revenue

Peru Stream Agreement

For the three months ended March 31, 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:

Balance, January 1, 2024 $ 418.5
Amortization of deferred revenue
Liability drawdown (74.3 )
Variable consideration adjustments - prior periods 3.8
Accretion on streaming arrangements
Current year additions 24.0
Variable consideration adjustments - prior periods 0.2
Balance, December 31, 2024 $ 372.2
Amortization of deferred revenue (note 4a)
Liability drawdown (19.4 )
Variable consideration adjustments - prior periods (9.9 )
Accretion on streaming arrangements (note 4d)
Current year-to-date additions 5.0
Variable consideration adjustments - prior periods (0.6 )
Balance, March 31, 2025 $ 347.3

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 three months ended March 31, 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:

Mar. 31, 2025 Dec. 31, 2024
Current $ 57.3 $ 63.1
Non-current 290.0 309.1

$ 296.9 $ 12.3 $ 9.6 $ 5.5 $ 6.4 $ 330.7
^1^ Relates primarily to flow-through share premiums, restructuring costs and other non-capital provisions.

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 three months ended March 31, 2025, the Company recorded a non-cash loss of $12.8 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 a decrease 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 March 31, 2025, decommissioning, restoration and similar liabilities have been discounted to their present value at rates ranging from 2.47% to 4.70% per annum (December 31, 2024 - 2.87% to 4.88%), using pre-tax, risk-free interest rates that reflect the estimated maturity of each specific liability.

During the three months ended March 31, 2024, the Company recorded a non-cash gain of $5.3 million in the condensed consolidated interim statements of income mainly related to a revaluation adjustment to the Flin Flon environmental reclamation provision.

Assumed conversion: warrants 22,435 21,636
Diluted weighted average common shares outstanding 395,708,530 350,970,348

The calculation of dilutive weighted-average number of common shares excludes the impact of 126,921 shares for the three months ended March 31, 2025 (three months ended March 31, 2024 - 163,059). 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.

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 period between provisional pricing and final pricing is typically up to three months.

Changes in fair value of provisionally priced receivables are presented in trade and other receivables when they relate to sales contracts and in trade and other payables when they relate to purchase contracts. At each reporting date, provisionally priced metals are marked-to-market based on the forward market price for the quotation period stipulated in the contract, with changes in fair value recognized in revenue for sales contracts and in inventory or cost of sales for purchase concentrate contracts. Cash flows related to changes in fair value of provisionally priced receivables are classified in operating activities.

SUMMARY

Achieved Record Adjusted EBITDA Driven by Strong Gold Production, Stable Copper Production and Industry leading Margins; 2025 Production and Cost Guidance Reaffirmed

  • Achieved revenue of $594.9 million and record quarterly adjusted EBITDA^1^of $287.2 million in the first quarter of 2025.

  • Strong financial results were driven by record low consolidated cash cost performance, as all three business units expanded operating cost margins and executed on planned strategies.

  • Consolidated copper production of 30,958 tonnes in the first quarter was in line with quarterly cadence expectations. Consolidated gold production of 73,784 ounces was better than quarterly cadence expectations driven by outperformance in Manitoba.

  • Industry-leading cost performance continues with record low consolidated cash cost^1^ and sustaining cash cost^1^ per pound of copper produced, net of by-product credits, of $(0.45) and $0.72, respectively, in the first quarter of 2025.

Summary of First Quarter Results

Consolidated copper production of 30,958 tonnes in the first quarter of 2025 was in line with quarterly production cadence expectations, while consolidated gold production of 73,784 ounces was better than quarterly production cadence expectations. Consolidated copper and gold production was lower than the fourth quarter of 2024 due to lower planned grades in Peru as Hudbay is completing the final stripping phase in the high-grade Pampacancha pit, partially offset by higher gold production in Manitoba from better-than-expected gold grades. Consolidated silver production of 919,775 ounces and zinc production of 6,265 tonnes in the first quarter of 2025 were lower than the fourth quarter of 2024 primarily due to lower grades in Peru as the Company completed planned stripping activities.

Cash generated from operating activities of $124.8 million decreased compared to the same period in 2024 and to the fourth quarter of 2024 as a result of higher cash taxes paid which are a function of higher profits in earlier quarters in Peru and Manitoba. Operating cash flow before change in non-cash working capital was $163.5 million during the first quarter of 2025, reflecting an increase of $16.0 million compared to the same period in 2024 and a decrease of $68 million compared to the fourth quarter of 2024. The increase compared to the first quarter of 2024 reflects the higher copper and gold realized prices during the quarter and strong operating cost performance, partially offset by lower sales volume and higher cash taxes paid. The decrease compared to the fourth quarter of 2024 was primarily the result of lower gold and copper sales volumes in Peru as expected.

First quarter adjusted EBITDA^1^was $287.2 million, a 12% increase compared to $257.3 million in the fourth quarter of 2024 as exposure to higher copper and gold prices in the quarter offset the lower sales volume. First quarter adjusted EBITDA increased by 34% compared to $215.0 million in the first quarter of 2024 as a result of the aforementioned lower sales volume was offset by the higher realized copper and gold prices during the quarter.

Net earnings attributable to owners in the first quarter of 2025 was $100.4 million, or $0.25 per share, compared to $22.3 million, or $0.06 per share, in the first quarter of 2024 and $21.2 million, or $0.05 per share, in the fourth quarter of 2024. The significant increase in earnings is the result of high gross margins from strong revenue growth on the back of higher realized copper and gold prices and strong unit cost control. In addition to higher mining and income tax expense experienced in the first quarter of 2025, the quarter was also impacted by various non-cash charges for revaluation loss of closed sites reclamation provisions, mark-to-market revaluation gain on various instruments, and foreign exchange gain, among other items.

Adjusted net earnings attributable to owners^1^and adjusted net earnings per share attributable to owners^1^ in the first quarter of 2025 were $93.8 million and $0.24 per share, respectively, after adjusting for various non-cash items on a pre-tax basis such as a non-cash loss of $12.8 million related to quarterly revaluation of Hudbay's closed site environmental reclamation provision, a $10.5 million variable consideration adjustment gain associated with the stream revenue and accretion, a $3.1 million mark-to-market revaluation gain on various instruments such as unrealized strategic copper hedges, investments and share-based compensation, a non-cash $3.1 million foreign exchange gain, and a $1.9 million gain related to flow-through share expenditures, among other items. This compares to adjusted net earnings attributable to owners^1^ and net earnings per share attributable to owners^1^ of $59.9 million and $0.17 per share in the first quarter of 2024 and $70.3 million and $0.18 per share in the fourth quarter of 2024. The sharp increase in adjusted net earnings attributable to owners^1^ and adjusted net earnings per share attributable to owners^1^ is for the same reasons discussed above for net earnings.

In the first quarter of 2025, consolidated cash cost per pound of copper produced, net of by-product credits^1^, achieved record low levels of $(0.45), compared to $0.45 in the fourth quarter of 2024. This improvement was a result of higher by-product credits and strong operating cost performance across all business units partially offset by expected lower production levels in Peru during the quarter. When compared to the first quarter of 2024, consolidated cash cost per pound of copper, net of by-product credits^1^ decreased by $0.61. This improvement is largely driven by the aforementioned higher by-product credits and strong operating cost performance during the quarter.

Consolidated sustaining cash cost per pound of copper produced, net of by-product credits^1^, was a record low at $0.72 in the first quarter of 2025, compared to $1.37 in the fourth quarter of 2024. The improvement was driven by the same factors impacting consolidated cash cost and slightly lower sustaining capital expenditures in the first quarter. First quarter of 2025 consolidated sustaining cash cost per pound of copper produced, net of by-product credit^1^, was lower than $1.00 in the first quarter of 2024. This decrease was primarily due to the same reasons outlined above, partially offset by higher sustaining capital expenditures.

Consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits^1^, was $0.97 in the first quarter of 2025, lower than $1.53 in the fourth quarter of 2024 mainly due to the same reason outlined above. First quarter of 2025 consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits^1^, was also lower than $1.29 in the same period in 2024 due to the same reasons outlined above as well as lower corporate G&A and regional costs.

As at March 31, 2025, total liquidity was $1,008.5 million, including $562.6 million in cash and cash equivalents, $20.0 million in short-term investments as well as undrawn availability of $425.9 million under Hudbay's revolving credit facilities. Net debt^1^ at the end of the first quarter was $526.1 million and remained consistent with the fourth quarter of 2024. Hudbay expects that the current liquidity together with cash flows from operations will be sufficient to meet the Company's liquidity needs for the year.

RECENT DEVELOPMENTS

Consolidated 100% Ownership in Copper Mountain

On March 27, 2025, Hudbay announced an agreement with Mitsubishi Materials Corporation ("MMC") to acquire MMC's 25% minority interest in Copper Mountain for an upfront cash payment of $4.5 million and up to $39.75 million in deferred and contingent cash payments. The transaction closed on April 30, 2025 and Hudbay now holds a 100% interest in the Copper Mountain mine. In connection with the transaction, Hudbay is solely responsible to settle any of Copper Mountain's outstanding obligations, including an intercompany loan owing to Hudbay, of which 25% represents approximately $104 million. The transaction is highly accretive to Hudbay's net asset value per share and increases Hudbay's exposure to a long-life, high-quality copper asset in a tier-1 mining jurisdiction. The additional attributable production from the Copper Mountain mine reinforces Hudbay's position as the second largest copper producer in Canada and further strengthens its position as a North American copper champion. Hudbay has initiated a review of its Canadian corporate structure which is anticipated to generate tax synergies through the sharing of tax pools between its various Canadian entities.

Continued Free Cash Flow Generation from Steady Operating Performance and Strong Copper and Gold Exposure

Hudbay has delivered seven consecutive quarters of meaningful free cash flow^1^ generation as a result of brownfield investments, continuous operational improvement efforts and steady cost control across the business. Over the last twelve months, the Company has generated more than $350 million in free cash flow^1^ and $895.7 million in adjusted EBITDA^2^.

While a majority of revenues continue to be derived from copper production, gold continues to represent more than 35% of total revenues. The unique copper and gold diversification is derived from copper and gold production in Peru, gold production from Manitoba and copper production contribution from British Columbia. The diversified and stable operating platform provides significant exposure to higher copper and gold prices. Using the mid-point of Hudbay's 2025 guidance ranges, a 10% increase in annual copper and gold prices would increase operating cash flow by $100 million and $56 million, respectively, as disclosed with Hudbay's 2025 guidance announcement in February^3^.

During the first quarter of 2025, the Company invested $25.5 million in growth capital expenditures relating to advancing high-return brownfield mill initiatives and greenfield copper projects to drive near-term and long-term production growth. Hudbay's balance sheet is well positioned to continue to advance its several growth initiatives. Net debt^2^ of $526.1 million in the first quarter of 2025 remained consistent with the fourth quarter of 2024 and reflects the deleveraging efforts completed in 2024. Hudbay's net debt to adjusted EBITDA ratio^2^ was 0.6x in the first quarter of 2025, in line with the fourth quarter of 2024 and significantly improved from 1.3x in the first quarter of 2024 because of successful deleveraging efforts throughout 2024.

Annual Reserve and Resource Update and Three-Year Production Guidance

Hudbay provided its annual mineral reserve and resource update and issued new three-year production guidance on March 27, 2025.

In Peru, current mineral reserve estimates total 517 million tonnes at 0.25% copper containing approximately 1.3 million tonnes of copper. In 2024, the Company increased mineral reserve estimates at Constancia to include the addition of a tenth mining phase in the Constancia pit after conducting positive geotechnical drilling and studies in 2023. This extended the expected mine life at Constancia by three years to 2041. Mining at the high-grade Pampacancha satellite pit commenced in 2021 and is expected to extend until early December 2025. The mine plan has smoothed Pampacancha production throughout 2025, resulting in total mill ore feed for 2025 from Pampacancha to be ~25%, lower than the typical one-third in prior years. Annual production at the Constancia operations is expected to average approximately 88,000^3^ tonnes of copper and 31,000^3^ ounces of gold over the next three years. This reflects steady copper production levels as higher mill throughput is expected to offset lower grades starting in 2026 after the depletion of Pampacancha in late 2025.

In Snow Lake, the current mineral reserve estimates a total of approximately 16 million tonnes with approximately 1.7 million ounces in contained gold and an expected mine life to 2037. Snow Lake's life-of-mine production schedule has been optimized for higher mill throughput rates at New Britannia, maximizing gold production and cash flows. In 2024, record annual gold production of 214,225 ounces was achieved in Snow Lake through a combination of higher metallurgical recoveries at the New Britannia and Stall mills, despite processing lower gold grades year-over-year, and the strategic allocation of more gold ore feed to the New Britannia mill. Annual gold production from Snow Lake is expected to average more than 193,000^3^ ounces over the next three years. The impressive operating performance has resulted in 2025 gold production guidance being 8% higher than the previous 2025 guidance of 185,000^3^ ounces, and 2026 gold production guidance being 3% higher than the previous 2026 guidance of 185,000^3^ ounces. Similarly, the midpoint of the 2027 gold production guidance is 17% higher than the anticipated 2027 production in the most recent technical report.

For further information and a detailed reconciliation, please see the discussion under the "Non-GAAP Financial Performance Measures" section of this MD&A.

In British Columbia, current mineral reserve estimates at Copper Mountain total 346 million tonnes at 0.25% copper and 0.12 grams per tonne gold with approximately 850 thousand tonnes of contained copper and 1.3 million ounces of contained gold. The current mineral reserve estimates continue to support a mine life until 2043, with significant upside potential for future resource conversion and mine life extension beyond 19 years through an additional 125 million tonnes of measured and indicated resources at 0.21% copper and 0.10 grams per tonne gold and 372 million tonnes of inferred resources at 0.25% copper and 0.13 grams per tonne gold, in each case, exclusive of mineral reserves. In 2025, the planned conversion of the third ball mill to a second SAG mill is anticipated to result in the ramp-up of mill throughput in the second half of the year. The mill throughput is anticipated to ramp up towards 50,000 tonnes per day in 2026. Annual production at the British Columbia operations is expected to average approximately 44,000^3^ tonnes of copper and 28,600^3^ ounces of gold over the next three years. Upon completion of Hudbay's optimization activities, 2027 copper production is expected to be 60,000^3^ tonnes, representing a 127% increase from 2024. 2027 expected copper production is also 20% higher than the production in the most recent technical report as a result of the deferral of higher grades from 2026 to 2027 in connection with the current accelerated stripping schedule.

Consolidated copper production over the next three years is expected to average 144,000^3^ tonnes, representing an increase of 4% from 2024 levels. The increase is due to higher expected copper production in British Columbia as a result of mill throughput ramp-up throughout 2025 and 2026 and higher grades in 2027 from the accelerated stripping schedule, which more than offsets the depletion of the high-grade Pampacancha deposit in Peru at the end of 2025. Consolidated gold production over the next three years is expected to average 253,000^3^ ounces, reflecting higher-than-expected annual gold production levels in Manitoba, as compared to prior guidance, a result of continued strong operating performance in Snow Lake.

Hudbay received the final major permit required for the development and operation of Copper World in January 2025, and the Company has since commenced a minority joint venture partner process. It is anticipated that any minority joint venture partner would participate in the funding of definitive feasibility study activities as well as the final project design and construction for Copper World. The Company has commenced work to support the definitive feasibility study and progress the project towards a potential sanction decision in 2026.

Copper World is expected to produce 85,000 tonnes of copper per year over an initial 20-year mine life, and the project generates an after-tax net present value ("NPV") (8%) of $1.7 billion with an internal rate of return ("IRR") of 25.5% using a copper price of $4.25 per pound. Copper World is one of the highest-grade open pit copper projects in the Americas with proven and probable mineral reserves of 385 million tonnes at 0.54% copper. There remains approximately 60% of the total copper contained in measured and indicated mineral resources (exclusive of mineral reserves), providing significant potential for future expansion and mine life extension. Once in production, Copper World is expected to be a meaningful copper producer in the U.S. domestic copper supply chain, which will help secure growing U.S. metal demand related to increased manufacturing capacity, infrastructure development, increased energy independence, domestic battery supply chain and strengthening the nation's security.

Enhancing Stakeholder Relationships at Mason

Hudbay's Mason project in Nevada is one of the largest undeveloped copper porphyry deposits in North America. Based on a preliminary economic assessment ("PEA") completed in 2021, Mason has the potential to be the third largest copper mine in the U.S. once in operation. The PEA contemplates a 27-year mine life with average annual copper production of approximately 140,000 tonnes over the first ten years of full production. Hudbay continues to advance local stakeholder engagement as well as additional metallurgical studies. While Mason is not as advanced as Copper World, Mason represents a long-term future development asset as part of Hudbay's pipeline of high-quality copper growth opportunities.

Exploration Update

Large Snow Lake Exploration Program Continues to Execute Threefold Strategy

Hudbay continues to execute the largest exploration program in Snow Lake in the Company's history through extensive geophysical surveying and multi-phased drilling campaigns as part of Hudbay's threefold exploration strategy:

• Near-mine exploration at Lalor and 1901 further increase near-term production and extend mine life - Positive initial step out drilling from the exploration drift at the 1901 deposit intersected significant copper-gold mineralization, including 14.3% copper over 2.5 metres and 8.3 grams per tonne gold over 3.2 metres. Additional exploration at 1901 is planned for 2025 targeting additional step-out drill holes to potentially extend the ore body and infill drilling to convert inferred mineral resources in the gold lenses to mineral reserves. Follow up drilling at Lalor Northwest continued to intersect copper-gold mineralization, including 16.4 grams per tonne gold over 3.7 metres and 2.6% copper over 3.5 metres. Hudbay continues to drill Lalor down-plunge and Lalor Northwest in 2025 through a surface drill program that is focused on testing the extent of the mineralization.

• Testing regional satellite deposits to utilize available processing capacity and increase production - Hudbay increased its land package by more than 250% in 2023 through the acquisition of Rockcliff Metals Corp. ("Rockcliff"), which included the addition of several known deposits located within trucking distance of the Snow Lake processing infrastructure. These newly acquired deposits, together with several deposits already owned by Hudbay in Snow Lake, have created an attractive portfolio of regional deposits in Snow Lake, including the Talbot, Rail, Pen II, Watts, 3 Zone and WIM deposits. The continued strong performance from the New Britannia mill operating at above 2,000 tonnes per day has freed up processing capacity at the Stall mill. There is approximately 1,500 tonnes per day of available capacity at the Stall mill which can be utilized by the regional satellite deposits to increase production and extend the life of the Snow Lake operations beyond 2037.

• Exploring large land package for new anchor deposit to significantly extend mine life - A majority of the newly acquired land claims have been untested by modern deep geophysics, which was the discovery method for the Lalor deposit. A large geophysics program is currently underway consisting of surface electromagnetic surveys using cutting-edge techniques that enable the team to detect targets at depths of almost 1,000 metres below surface. The planned geophysics program in 2025 is the largest geophysics program in Hudbay's history and includes 800 kilometres of ground electromagnetic surveys and an extensive airborne geophysics survey.

Signed Exploration Agreements with First Nations in Manitoba

Hudbay is proud to have reached exploration agreements with two First Nations groups in Manitoba in 2025:

• Kiciwapa Cree Nation - In February 2025, Hudbay signed its first-ever exploration agreement with the Kiciwapa Cree Nation, reflecting the Company's commitment to meaningful collaboration as Hudbay explores new mineral resources in the Snow Lake and Flin Flon regions.

• Mosakahiken Cree Nation - In April 2025, Hudbay signed an exploration agreement with the Mosakahiken Cree Nation, marking a significant step towards building a relationship based on alignment and transparency on its projects in the region, including the Talbot copper-zinc-gold deposit south of Snow Lake. The signing of this agreement represents a compelling opportunity for Hudbay to enhance future production and extend mine life at its Snow Lake operations through additional exploration activities in the region. A large exploration program at Talbot is planned for this summer.

Unlocking Value through Flin Flon Tailings Reprocessing

Hudbay continues to advance studies to evaluate the opportunity to reprocess Flin Flon tailings where more than 100 million tonnes of tailings have been deposited for over 90 years from the mill and the zinc plant. The studies are evaluating the potential to use the existing Flin Flon concentrator, which is currently on care and maintenance after the closure of the 777 mine in 2022, with flow sheet modifications to reprocess tailings to recover critical minerals and precious metals in an environmentally-friendly manner. The more advanced opportunity relates to the zinc plant tailings where metallurgical test work continues following positive results from the initial confirmatory drill program completed in 2024. The results confirmed the grades of precious metals and critical minerals previously estimated from historical zinc plant records. An early economic study to evaluate the opportunity to reprocess the zinc plant tailings has confirmed the potential for a technically viable reprocessing alternative, and the Company is progressing with further engineering work.

Maria Reyna and Caballito Drill Permits Proceeding Through Regulatory Process

Hudbay controls a large, contiguous block of mineral rights with the potential to host satellite mineral deposits in close proximity to the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna property. The Company commenced the drill permitting process at Maria Reyna and Caballito after completing a surface rights exploration agreement with the community of Uchucarcco in August 2022. As part of the drill permitting process, environmental impact assessment (EIA) applications were approved by the government in June 2024 for Maria Reyna and September 2024 for Caballito. This represents one of several steps in the drill permitting process, and the government is targeting completion of the process in 2025.

Normal Course Issuer Bid

Hudbay's board of directors has approved, subject to the approval of the TSX, a normal course issuer bid ("NCIB") for up to 5% of the Company's issued and outstanding common shares. The NCIB will be conducted in accordance with the requirements of the TSX and applicable securities laws, with purchases to be made as appropriate opportunities arise from time to time. Any common shares purchased under the NCIB will be cancelled upon their purchase. Hudbay intends to fund any purchases from its cash flow from operations.

Overview

Copper production was lower than comparable periods but in line with mine plan expectations as the final phase of planned stripping at the Pampacancha deposit was underway during the first quarter of 2025. This resulted in planned lower head grades to the mill as Constancia ore represented a majority of the ore feed during the first quarter of 2025. Peru operations continued to benefit from strong and consistent mill throughput in 2025, averaging approximately 90,200 tonnes processed per day in the first quarter of 2025, partially offsetting the planned lower head grades. The operations continued to deliver strong cost control, resulting in lower combined unit cost compared to the fourth quarter of 2024.

The Company continues to evaluate opportunities to further increase mill throughput after the Peruvian Ministry of Energy and Mines approved a regulatory change in 2024 to allow mining companies in Peru to increase throughput by up to 10% above permitted levels. Hudbay is advancing engineering studies for the construction of a pebble crusher at Constancia commencing in late 2025, which is expected to further increase throughput levels starting in the second half of 2026.

Mining Activities

Total ore mined in the first quarter of 2025 increased by 89% compared to the same period in 2024, in line with mine plan expectations as the Company was advancing planned stripping activities in the first quarter of 2024. Ore mined from Pampacancha during the first quarter of 2025 decreased to 0.4 million tonnes compared with 2.2 million tonnes in the first quarter of 2024, as Hudbay is performing the final stripping phase in the Pampacancha pit prior to depletion in late 2025. Ore mined from Constancia significantly increased during the first quarter of 2025 compared to recent quarters, in line with mine plan expectations.

Milling Activities

The mill continued to maintain high throughput levels averaging approximately 90,200 tonnes per day in the first quarter of 2025. Milled copper and gold grades decreased by 17% and 67%, respectively, in the first quarter of 2025 compared to the same period in 2024, in line with the mine plan due to planned lower ore feed from Pampacancha. The Constancia mill achieved copper recoveries of 85% in the first quarter of 2025, consistent with the same period in 2024 but lower than the fourth quarter due to planned lower grades. Recoveries of gold and silver during the first quarter of 2025 were 57% and 66%, respectively, representing a decrease of 23% and 7%, respectively, compared to the same period in 2024, but remained in line with Hudbay's metallurgical models for the ore types that were being processed.

Production and Sales Performance

The Peru operations produced 20,293 tonnes of copper, 7,869 ounces of gold, 554,692 ounces of silver and 397 tonnes of molybdenum during the first quarter of 2025, in line with mine plan quarterly cadence expectations. Production of copper, gold and silver in the first quarter of 2025 was lower than the same period in 2024 and the most recent quarter due to planned lower grades as a larger portion of lower grade Constancia ore was processed in the current quarter.

Quantities of metal sold during the first quarter of 2025 were lower than the corresponding period in 2024 and the fourth quarter of 2024 primarily due to planned lower production as a result of lower grades. Higher copper concentrate inventories at the port on December 31, 2024 were sold as expected in early 2025, and inventory levels have normalized as of March 31, 2025.

*Copper equivalent production is calculated using the quarter average LME prices for each metal excluding molybdenum.

Cost Performance

Combined mine, mill and G&A unit operating cost in the first quarter of 2025 was $11.09 per tonne, 2% higher than the same period in 2024 primarily due to slightly higher mining and milling costs. Combined mine, mill and G&A unit operating cost was 27% lower than the fourth quarter of 2024 due to a planned semi-annual mill maintenance shutdown in the fourth quarter and lower overall onsite costs.

Cash cost per pound of copper produced, net of by-product credits, in the first quarter of 2025 was $1.11, outperforming quarterly cadence expectations as a result of strong operating cost performances and higher by-product prices.  Cash cost per pound of copper produced, net of by-product credits was higher than the same period in 2024 and the fourth quarter of 2024 due to planned lower copper production and gold by-product credits, partially offset by lower treatment, refining and freight charges.

Sustaining cash cost per pound of copper produced, net of by-product credits, was $1.92 in the first quarter of 2025, an increase compared to the prior periods in 2024 primarily due to the same factors described above for the cash cost variance.

Overview

The Manitoba operations achieved impressive metal production and cost performance in the first quarter of 2025, significantly exceeding budgeted targets.

The Lalor mine achieved strong production results in the first quarter, averaging 4,300 tonnes per day, demonstrating resilience despite one-off ore handling challenges in March. The mine maintained focus on ore quality, implementing stope modifications and improving mucking productivity rates. A significant focus is on capital development, aimed at securing high-grade copper-gold mineralization from Zone 27 and preparing for the next copper-gold mining front in Zone 17.

The exploration and haulage drifts at 1901 maintained solid development progress towards the deposit in the first quarter of 2025. A recent drill hole from the exploration drift intersected zinc-rich massive sulphides 20 metres earlier than anticipated, confirming planned first ore in the second quarter of 2025. The next two years will focus on exploration, definition drilling, orebody access, and establishing critical infrastructure for full production in 2027.

The New Britannia mill continued its exceptional performance from recent quarters, achieving throughput of approximately 2,100 tonnes per day in the first quarter of 2025. New elongated cyclones were installed at New Britannia during the first quarter, mirroring successful upgrades at the Stall mill, and supporting Hudbay's strategy of low-capital projects to boost throughput and maintain gold recoveries.

At the Stall mill, a slight quarter-over-quarter reduction in throughput occurred as more ore was diverted to New Britannia in the first quarter. However, benefits from recent recovery improvement programs continuing to be realized, with gold recoveries exceeding prior year figures. Efforts continue to optimize recovery, particularly by reducing grind size.

The Flin Flon operations continued to make significant progress on the smelter building demolition project, which began in September 2024, with approximately 50% of the buildings slated for demolition now complete.

A Mining Fundamentals training program was launched in 2025 in partnership with the Northern Manitoba Sector Council. This comprehensive nine-week course, combining essential skills training with hands-on mining experience, has successfully prepared individuals for the mining workforce. Nine participants from the Opaskwayak Cree Nation and the Mosakahiken Cree Nation have completed the program and secured full-time positions at Hudbay's Lalor mine. Hudbay looks forward to the continued success of this program and its positive impact on both the Company's operations and northern Manitoba communities.

Mining Activities

Total ore mined in Manitoba in the first quarter of 2025 was 6% lower than the comparable quarters in 2024 primarily due to temporary ore handling challenges at Lalor in March that were promptly resolved. Gold grades were better than expected resulting in a 13% and 18% increase from the first quarter and fourth quarter of 2024, respectively. Copper, zinc and silver grades were in line with mine plan expectations. The first quarter of 2025 saw significant improvements in ore quality, aligned with improvements in mining techniques, most notably in longhole muck fragmentation, and anticipated higher grade precious metal sequences.

Milling Activities

Consistent with Hudbay's strategy of allocating more Lalor ore feed to New Britannia, the New Britannia mill throughput averaged approximately 2,100 tonnes per day in the first quarter of 2025, approximately 12% increase from the first quarter of 2024 and slightly higher than the fourth quarter of 2024. Gold recovery in the first quarter of 2025 was 90%, representing an increase of 2% compared to the same period in 2024 and in line with the fourth quarter of 2024.

During the first quarter of 2025, the Stall mill processed 2% less ore compared with the same period in 2024, which is aligned with the strategy of allocating more Lalor ore feed to New Britannia, as noted above. The Stall mill achieved gold recoveries of 70% in the first quarter of 2025, reflecting benefits from recent recovery improvement programs.

Production and Sales Performance

The Manitoba operations produced 60,354 ounces of gold, 3,469 tonnes of copper, 6,265 tonnes of zinc and 285,603 ounces of silver during the first quarter of 2025. Compared to the first quarter of 2024, production of gold, copper and silver in the first quarter of 2025 increased by 6%, 10% and 30%, respectively, while production of zinc declined by 29%, consistent with mine sequence and strategy to mine higher amounts of gold ore as well as higher New Britannia throughput. Compared to the fourth quarter of 2024, production of gold meaningfully increased by 17% due to higher grades.

Quantities of metal sold during the first quarter of 2025 were lower for all metals with the exception of silver, as compared to the first quarter of 2024, due to higher copper and zinc concentrate in inventory at the end of March 2025.

Cost Performance

The Manitoba operations continued to drive operating efficiencies, resulting in improved cost performance on both a unit operating basis and on a cash cost basis.

Lalor mining costs during the first quarter of 2025 decreased by 2% compared to the same period in 2024, as a result of efficiency improvements more than offsetting inflationary factors and lower tonnes mined. New Britannia milling costs decreased by 13% during the first quarter of 2025 versus the same period in 2024, primarily as a result of higher throughput as described earlier and lower overall costs. New Britannia milling costs also decreased by 1% compared to the most recent quarter with lower overall costs. Stall milling costs were 12% and 22% lower in the first quarter of 2025 compared to the first quarter and fourth quarter of 2024, respectively, primarily due to lower overall costs. Combined mine, mill and G&A unit operating costs in the first quarter of 2025 were C$214 per tonne, representing a 9% decrease compared to the same period in 2024, primarily due to lower mine and mill costs and higher tonnes milled. In comparison to the fourth quarter of 2024, combined mine, mill and G&A unit operating costs decreased by 8% in the first quarter of 2025, primarily due to lower mine and mill costs.

Cash cost per ounce of gold produced, net of by-product credits, in the first quarter of 2025 was $376, a significant 49% decrease compared to the same period in 2024 and a 38% decrease compared to the fourth quarter of 2024 primarily due to higher gold production and lower mining and milling costs as a result of continued operating efficiencies and favorable exchange rates.

Sustaining cash cost per ounce of gold produced, net of by-product credits, in the first quarter of 2025 was $626, a 34% decrease compared to the same period in 2024 and a 31% decrease compared to the fourth quarter of 2024, primarily due to the same factors affecting cash cost, partially offset by higher sustaining capital costs during the quarter.

^2^ Copper Mountain mine results are stated at 100%. As at March 31, 2025, Hudbay owned 75% of the Copper Mountain mine. Subsequent to quarter end, Hudbay completed an acquisition of the remaining 25% interest and as of the date of this MD&A Hudbay owns 100% of the Copper Mountain mine.

Overview

Hudbay continues its focus on advancing optimization plans at the Copper Mountain mine, including opening up and optimizing the mine ore feed to the plant and implementing plant improvement initiatives that mirror Hudbay's successful processes at Constancia. These optimization initiatives have successfully increased the total tonnes moved and improved mill reliability.

Mining activities are focused on continuing to execute the three-year accelerated stripping program intended to bring higher grade ore into the mine plan. In January, Hudbay completed feasibility engineering to debottleneck and increase the nominal plant capacity to its permitted capacity of 50,000 tonnes per day earlier than contemplated in the most recent technical report. This is expected to be achieved through the conversion of the third ball mill to a second SAG mill, which remains on track for completion in the second half of 2025.

Mining Activities

Total ore mined at Copper Mountain in the first quarter of 2025 was 2.6 million tonnes, a decrease of 29% compared to the first quarter of 2024, as planned, ore stockpiles were utilized as ore feed to the mill while the mine operation team continued to increased waste stripping activities. Total ore mined increased by 12% compared to the fourth quarter of 2024 and total material moved continued to ramp up in the quarter as a result of effective usage of the mining fleet to execute the accelerated stripping program to access higher head grades. The focus in the first quarter of 2025 was on mining efficiencies and operator recruitment to effectively utilize the available haul truck fleet. As a result, total material moved is expected to increase quarter-over-quarter in 2025 as per the mine plan.

Milling Activities

The mill processed 2.8 million tonnes of ore during the first quarter of 2025. Ore processed in the first quarter of 2025 was  lower than the first and fourth quarter of 2024, limited by both planned and unplanned maintenance and elevated clay material which impacted the secondary crushing circuit. In the first quarter of 2025, a number of initiatives were advanced to address these issues and other identified constraints to improve throughput. Several mill initiatives have been implemented in 2025, including crushing circuit chute modifications, recovery improvements, reprogramming the mill expert system, installation of advanced semi-autogenous grinding control instrumentation, redesigned SAG liner package and updated operational procedures intended to remove magnetite from the pebble stream. Progressive improvements are expected to continue through 2025.

Milled copper grades during the first quarter of 2025 were 22% higher than the first quarter of 2024. The accelerated stripping efforts unlocked a high-grade mining sequence during the first quarter of 2025, which reduced the amount of ore processed from stockpile and resulted in the higher grades this quarter compared to 2024. Copper recoveries of 78% were 6% lower than the first quarter of 2024 impacted by ore feed material and the ramp-up periods following the planned and unplanned maintenance shutdowns during the quarter. Milled gold grades were higher in the first quarter of 2025 compared to the same period in 2024, resulting in 3% higher gold recoveries in the first quarter of 2025.

Production and Sales Performance

The British Columbia operations produced 7,196 tonnes of copper, 5,561 ounces of gold and 79,480 ounces of silver. Production of copper and gold increased by 2% and 26%, respectively, compared to the first quarter of 2024 due to higher grades, partially offset by lower mill throughput. Production of silver decreased by 10% compared to the first quarter of 2024 primarily as a result of lower head grades from the use of stockpiled ore. Production of copper, gold and silver increased by 21%, 20% and 35%, respectively compared to the fourth quarter of 2024, largely due to higher grades.

Quantities of copper and silver sold during the first quarter of 2025 were lower by 11% and 28%, respectively, compared to the first quarter of 2024 mainly due to higher copper concentrate inventory at the end of March 2025. Gold quantities sold during the first quarter of 2025 was higher by 46% compared to the first quarter of 2024, in line with the increase in gold production during the quarter.

*Copper equivalent production is calculated using the quarter average LME prices for each metal excluding molybdenum. Copper Mountain mine production are stated at 100%. As at March 31, 2025, Hudbay owned 75% of the Copper Mountain mine. Subsequent to quarter end, Hudbay completed the acquisition of the remaining 25% interest and as of the date of this MD&A Hudbay owns 100% of the Copper Mountain mine.

Cost Performance

Combined mine, mill and G&A unit operating costs in the first quarter of 2025 were C$25.98 per tonne milled, higher than the first quarter and fourth quarter of 2024. The increase compared to the first quarter of 2024 was primarily due to lower ore milled partially offset by lower costs. The increase compared to the fourth quarter of 2024 was due to higher mining and G&A costs and lower ore milled, partially offset by lower milling costs.

Cash cost and sustaining cash cost per pound of copper produced, net of by-product credits, in the first quarter of 2025 were $2.44 and $4.24, respectively. Cash costs were 30% and 19% lower than in the first and fourth quarter of 2024, respectively, largely due to higher by-product credits and the benefit from the continued focus on optimization efforts. Sustaining cash costs were 13% lower than the first quarter of 2024 mainly as a result of improvements to cash costs partially offset by higher capital including planned higher capitalized stripping costs in accordance with Hudbay's accelerated stripping program to access higher grade ore. Sustaining cash costs were 26% lower than the fourth quarter of 2024 due to the same factors affecting cash costs as well as lower sustaining capital expenditures.

^2^ Copper Mountain mine results are stated at 100%. As at March 31, 2025, Hudbay owned 75% of the Copper Mountain mine. Subsequent to quarter end, Hudbay completed the acquisition of the remaining 25% interest and as of the date of this MD&A Hudbay owns 100% of the Copper Mountain mine.

Hudbay is on track to achieve its 2025 production guidance for all metals in British Columbia, and continues to expect higher production in the second half of the year as the mill improvement projects take effect. With first quarter cash cost at the low-end of the 2025 guidance range, Hudbay is well positioned to achieve the full year 2025 cash cost guidance range in British Columbia.

FINANCIAL REVIEW

Financial Results

In the first quarter of 2025, Hudbay recorded net earnings attributable to owners of $100.4 million compared to net earnings on the same basis of $22.3 million in the first quarter of 2024, representing an increase in net earnings attributable to owners of $78.1 million.

Revenue

Revenue for the first quarter of 2025 was $594.9 million, $69.9 million higher than the same period in 2024, primarily due to higher prices for gold and copper. Production levels while lower than the comparative period, are in line with the mine plan for Peru, Manitoba and British Columbia for the first quarter of 2025.

While a majority of revenues continue to be from copper, gold represented a significant portion of total revenues at 38% in the first quarter of 2025. This is as a result of higher gold production and strong leverage to higher gold prices compared to the first quarter of 2024, increasing commodity diversification and improving overall revenues.

Realized sales prices

This measure is intended to enable management and investors to understand the average realized price of metals sold to third parties in each reporting period. The average realized price per unit sold does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers and should not be considered in isolation or a substitute for measures of performance prepared in accordance with IFRS.

For sales of copper, zinc, gold and silver the Company may enter into non-hedge derivatives ("QP hedges") which are intended to manage the provisional pricing risk arising from quotational period terms in concentrate sales agreements. The gains and losses on QP hedges are included in the calculation of realized prices. Hudbay expects that gains and losses on QP hedges will offset provisional pricing adjustments on concentrate sales contracts.

The table below summarizes Hudbay's realized prices for first quarter 2025, fourth quarter of 2024 and the first quarter 2024, respectively:

Realized prices^1^ for the

All values are in US Dollars.

^1^Realized prices exclude refining and treatment charges and are on the sale of finished metal or metal in concentrate. Realized prices include the effect of provisional pricing adjustments on prior period sales and the effect of sales which are subject to exposure from fluctuating market prices.
^2^ London Metal Exchange average for cash copper and zinc prices.
^3^Sales of gold and silver from Constancia mine are subject to Hudbay's precious metals stream agreement with Wheaton, pursuant to which Hudbay recognizes deferred revenue for precious metals deliveries and also receive cash payments. Stream sales are included within realized prices and their respective deferred revenue and cash payment rates can be found on page 33 of this MD&A.

In addition to QP hedges, the Company may periodically undertake metal price hedging in accordance with Board approved policies to achieve strategic objectives, including locking in favourable metal prices to ensure minimum cash flows during or after the construction of a mine or during a period of reduced liquidity, to manage cash flows at shorter life or higher cost operations or as part of a financing arrangement. The realized prices, denoted in the table above, excludes the impact of derivative mark-to-market gains and losses on these non-QP hedges, which are included in change in fair value of financial instruments in Hudbay's condensed consolidated interim statements of income.

As of March 31, 2025, Hudbay had the following non-QP hedges outstanding:

  • Forward sales contracts at the Copper Mountain mine for a total of 1.3 million pounds of copper in April 2025 at an average price of $3.95 per pound; and

  • Zero-cost collar program at the Copper Mountain mine for 1.7 million pounds of copper in April 2025 at an average floor price of $3.88 per pound and an average cap price of $4.14 per pound.

The following tables provide a reconciliation of average realized price per unit sold, by metal, to revenues as shown in the consolidated interim financial statements.

Total cost of sales for the first quarter of 2025 was $363.6 million, reflecting a decrease of $9.4 million compared to the first quarter of 2024. Manitoba cost of sales decreased by $8.2 million in the first quarter of 2025, primarily as a result of lower production resulting in lower mining, milling and depreciation offset by higher G&A during the quarter from higher profit sharing plan costs, compared to the same period of 2024. Peru cost of sales decreased by $3.1 million in the first quarter of 2025, compared to the same period of 2024 mainly due to lower depreciation and G&A costs as a result of planned lower production volumes. This was partially offset by the drawdown of inventory balances from the end of 2024 causing a higher change in product inventory. British Columbia cost of sales increased by $1.9 million primarily driven higher depreciation and G&A, partially offset by lower mining and milling costs caused by higher capitalized waste stripping and a weaker Canadian dollar compared with the same period of 2024.

For details on unit operating costs, refer to the respective tables in the "Operations Review" section of this MD&A.

For the first quarter of 2025, other significant variances in expenses, compared to the same period in 2024, include the following:

  • Net finance expenses decreased by $29.6 million primarily due to a $8.4 million increase in mark-to-market gain on investments, a decrease in foreign exchange loss by $7.9 million, a $3.5 million decrease in the relative revaluation loss of the gold prepayment liability, a decrease of $3.3 million from interest expense on long-term debt benefiting from the retirement of senior notes and repayment of the Peruvian revolving credit facility in 2024, an increase of $3.1 million from interest income, and a decrease of $1.7 million of stream financing costs.

  • Other expenses decreased by $11.1 million primarily due to a decrease of $8.5 million in the write-off of previously capitalized PP&E costs, decrease of $1.2 million in amortization of certain community costs, increase of $1.2 million in the amortization of obligation related to flow through share deferred liability, net of provisions and an increase of $1.1 million in option proceeds from the Marubeni agreement.

  • Selling and administrative expenses decreased by **** $2.9 million reflecting a lower share-based compensation expense as a result of a comparative decrease in share price during the current period, partially offset by adjustments to the performance based multiplier on certain share units.

  • Exploration expenses increased by $1.3 million primarily due to Hudbay's planned Snow Lake exploration program consisting of modern geophysical programs and multi-phased drilling campaigns, much of which is funded by flow-through financing.

  • Re-evaluation adjustment - environmental provision contributed an increase of $18.1 million in expenses compared to the same period in 2024 due to the relative revaluation of the environmental reclamation provision on Hudbay's Manitoba non-producing sites from changes in long term risk-free discount rates and inflation rates.

Given the long term nature of the reclamation cash flows, the related environmental reclamation provision is highly sensitive to changes in inflation rates and long-term risk-free discount rates and, as such, Hudbay may continue to experience significant quarterly environmental reclamation provision revaluations.

Tax Expense

For the three months ended March 31, 2025, tax expense increased by $22.8 million compared to the same period in 2024. The following table provides further details:

Income Tax Expense/Recovery

Applying the estimated Canadian statutory income tax rate of 26.7% to Hudbay's net earnings before taxes of $171.3 million for the year-to-date of 2025 would have resulted in a tax expense of approximately $45.7 million; however, Hudbay recorded an income tax expense of $55.9 million. The primary item causing Hudbay's effective income tax rate to be different than the 26.7% estimated Canadian statutory income tax rate is the following:

  • The tax expense with respect to Hudbay's foreign operations is recorded using an income tax rate other than the Canadian statutory income tax rate of 26.7%, resulting in a tax expense of $10.6 million.

Mining Tax Expense

For the year-to-date of 2025, Hudbay recorded a mining tax expense of $16.2 million. Effective mining tax rates can vary significantly based on the composition of Hudbay's earnings and the expected amount of mining taxable profits. Corporate costs and other costs not related to mining operations are not deductible in computing mining profits. A brief description of how mining taxes are calculated in Hudbay's various business units is discussed below.

Manitoba

The Province of Manitoba imposes mining tax on earnings related to the sale of mineral products mined in the Province of Manitoba (mining taxable profit) at the following rates:

  • 10% of total mining taxable earnings if mining profit is C$50 million or less;

  • Between mining earnings of C$50 and $C55 million, mining tax is equal to a minimum of C$5 million plus mining earnings less C$50 million multiplied by 65%;

  • 15% of total mining taxable earnings if mining profits are between C$55 million and C$100 million;

  • Between mining earnings of C$100 million and C$105 million, mining tax is equal to a minimum of C$15 million plus mining earnings less C$100 million multiplied by 57%; and

  • 17% of total mining taxable earnings if mining profits exceed C$105 million.

Hudbay estimates that the deferred tax rate that will be applicable when temporary differences reverse will be approximately 10.0%.

Peru

The Peruvian government imposes two parallel mining tax regimes, the Special Mining Tax and the Modified Royalty, on companies' operating mining income on a sliding scale, with progressive rates ranging from 2.0% to 8.4% and 1.0% to 12.0%, respectively. Based on financial forecasts, Hudbay has recorded a deferred tax liability as at March 31, 2025, at the tax rate  expected to apply when temporary differences reverse.

British Columbia

The Province of British Columbia imposes a 13% net revenue tax on the sale of mineral products mined in the province of British Columbia after the mine owner has recovered the capital invested in the mine and its "Cumulative Expenditure Account" ("CEA") no longer has a balance. The tax is paid on the profit in excess of the capital that has been invested in the mine. British Columbia mineral tax is deductible for federal and provincial income tax purposes.

While there is a balance in the CEA account, the mine owner must pay a "Net Current Proceeds" ("NCP") tax of 2%. Any amounts paid as NCP can then be claimed in the future against net revenue taxes payable.

Hudbay estimates that the effective tax rate that will be applicable when temporary differences reverse will be approximately 9.49%.

LIQUIDITY AND CAPITAL RESOURCES

Total liquidity substantially increased by 63% to $1,008.5 million at March 31, 2025 from $618.9 million at March 31, 2024.

As at March 31, 2025, Hudbay's liquidity includes $562.6 million in cash, $20.0 million in short-term investments as well as undrawn total availability of $425.9 million under Hudbay's revolving credit facilities.

Senior Unsecured Notes

As at March 31, 2025, Hudbay had $575.0 million aggregate principal amount of 2026 Notes and $542.4 million aggregate principal amount of 2029 Notes.

Senior Secured Revolving Credit Facilities

Hudbay has two senior secured revolving credit facilities with total commitments of $450 million ("the Credit Facilities") for its Canadian and Peruvian businesses on substantially similar terms and conditions. These facilities include an accordion feature that allows Hudbay the option to increase the facility by an additional $150 million at Hudbay's discretion over the four-year term.

As at March 31, 2025, there were nil cash drawings under the Credit Facilities and $24.1 million in letters of credit secured under the Canadian Facility.

As at March 31, 2025, Hudbay was in compliance with its covenants under the Credit Facilities.

C$130 Million Bilateral Letter of Credit Facility

Hudbay has a C$130.0 million bilateral letter of credit facility ("LC Facility") with a major Canadian financial institution. The LC Facility has no financial covenants and enables Hudbay to issue up to C$130.0 million of letters of credit to beneficiaries on an unsecured basis at attractive rates, including C$30.0 million sub-limit for financial letters of credit. As at March 31, 2025, the Manitoba business unit had drawn $52.7 million in letters of credit under the LC Facility.

Surety Bonds and Letters of Credit

As at March 31, 2025, the Arizona business unit had $18.4 million in surety bonds issued to support future reclamation and closure obligations and the Peru business unit had $135.1 million in letters of credit and surety bonds issued with various Peruvian financial institutions to support future reclamation and other operating matters. In addition, the British Columbia business unit had $45.7 million in surety bonds issued to support future reclamation and $1.0 million in surety bonds issued to support the hydro used at Copper Mountain mine, and to Fisheries and Oceans Canada for fish monitoring. The British Columbia business unit also had $0.6 million in cash collateralized letters of credit issued with various Canadian financial institutions related to other operating matters.

Working Capital

Working capital increased by $86.7 million to $598.0 million from December 31, 2024 to March 31, 2025, primarily due to a decrease in taxes payable of $64.2 million, an increase in trade and other receivables of $34.2 million mainly related to the timing of receiving statutory receivables, a decrease in trades and other payable of $21.6 million, an increase in cash and cash equivalents of $20.8 million, and a decrease in deferred revenue of $5.8 million. Partially offsetting these items was a decrease in short-term investment of $20.0 million, a decrease in inventories of $15.8 million, a decrease in other financial assets and taxes receivable of $13.0 million, an increase in leases and other liabilities of $6.0 million, an increase other financial liabilities of $2.9 million, and a decrease in prepaid and other expenses of $2.2 million.

Cash Flows

The following table summarizes Hudbay's cash flows for the three months ended March 31, 2025, December 31, 2024 and March 31, 2024:

(in $ millions) Three months ended
Mar. 31, 2025 Dec. 31, 2024 Mar. 31, 2024
Operating cash flow before change in non-cash working capital 163.5 231.5 147.5
Change in non-cash working capital (38.7 ) 6.6 (7.9 )
Cash generated from operating activities 124.8 238.1 139.6

Cash used in financing activities (20.8 ) (36.9 ) (47.6 )
Effect of movement in exchange rates on cash 1.1 (3.1 ) 1.5
Net increase in cash and cash equivalents 20.8 98.5 34.6

Cash Flow from Operating Activities

Operating cash flow before change in non-cash working capital was $163.5 million during the first quarter of 2025, reflecting an increase of $16.0 million compared to the first quarter of 2024. Cash generated from operating activities was $124.8 million during the first quarter of 2025, a decrease of $14.8 million compared to the same period in 2024. The increase in operating cash flows before change in working capital compared with the first quarter of 2024 was primarily the result of strong realized prices for all metals which more than offset the lower sales volumes. The decrease in cash generated from operating activities compared to the same periods in 2024 is the result of higher cash taxes paid which are function of higher profits in earlier quarters in Peru and Manitoba that were subsequently payable.

Cash Flow from Investing and Financing Activities

During the first quarter of 2025, Hudbay spent $105.1 million in investing and financing activities, primarily driven by $91.4 million in capital expenditures, $13.8 million in purchase of investments, $13.4 million in capitalized lease and equipment financing payments, $3.8 million in community agreement payments and $3.2 million in other financing costs mainly related to Hudbay's Credit Facilities and foreign withholding taxes. These cash outflows were partially offset by cash inflows of $20.0 million from the release of the guaranteed investment certificates and $6.0 million of investment income received.

^1^Peru and British Columbia sustaining capital expenditures include capitalized stripping costs.
^2^ Other capitalized costs primarily include right-of-use lease and equipment financing additions, which are excluded from guidance in 2025, in addition to non-cash deferred stripping
^3^Includes 100% of Copper Mountain mine production. As at March 31, 2025, Hudbay owned 75% of the Copper Mountain mine. Subsequent to quarter end, Hudbay completed the acquisition of the remaining 25% interest and as of the date of this MD&A, Hudbay owns 100% of the Copper Mountain mine.

Total capital additions increased by $31.3 million, in the first quarter of 2025, compared to the same period in 2024, primarily due to higher sustaining capital expenditures at the Copper Mountain mine. In addition, growth capital expenditure at Arizona increase by $7.0 million as The Company commenced work to support the feasibility study and advance the project towards a sanction decision in 2026.

Sustaining capital expenditures in Manitoba during the first quarter of 2025 were $12.5 million, representing an increase of $2.8 million, compared to the same period in 2024 mostly due to higher capital development at Lalor. Sustaining capital expenditures in Peru, during the first quarter of 2025 were $28.5 million, representing an increase of $3.3 million compared to the same period in 2024 as a result of increased civil work projects at Constancia. Sustaining capital expenditures in British Columbia, during the first quarter of 2025 were $21.5 million, which included $14.7 million of capitalized stripping related to Hudbay's planned three-year accelerated stripping campaign to access higher grade ore.

Growth capital spending in Manitoba during the first quarter of 2025 were $2.2 million, representing an increase of $0.9 million compared to the same period in 2024. The increase mainly relates to the development of an exploration access drift at 1901. Growth capital expenditures in Peru, during the first quarter of 2025 were $0.9 million, representing an increase of $0.8 million compared to the same period in 2024. The increase mainly relates to the installation of a pebble crusher to increase mill throughput and rougher cell engineering studies. Growth capital spending in British Columbia during the first quarter of 2025 were $11.0 million, representing an increase of $10.7 million. The increase relates to the conversion of the third ball mill to a second SAG mill at Copper Mountain as part of the continued optimization efforts. Arizona's capital expenditures during the first quarter of 2025 were $11.4 million, mainly related to ongoing carrying costs and feasibility preparation.

Capitalized exploration during the first quarter of 2025 was $1.1 million.

Capital Commitments

As at March 31, 2025, Hudbay had outstanding capital commitments in Canada of approximately $24.7 million, of which $12.6 million can be terminated, approximately $34.4 million in Peru primarily related to sustaining capital commitments and exploration option agreements, all of which can be terminated, and approximately $62.2 million in Arizona, primarily related to Hudbay's Copper World project, of which $60.0 can be terminated.

^2^ Annual consolidated results may not calculate based on amounts presented in this table due to rounding.
^3^ The Company acquired Copper Mountain on June 20, 2023, and Q3 2023 represented the first full quarter of Copper Mountain production included in the Company's financial results.

On a quarterly basis, the Company's revenue is primarily impacted by metal prices, production mix and sales volumes of the key metals Hudbay produces. In addition to these factors, gross profit, net earnings (loss) attributable, earnings (loss) per share attributable, operating cash flow before change in non-cash working capital and adjusted EBITDA are also impacted by input costs. Net earnings (loss) and earnings (loss) per share are further impacted by net finance expense and re-evaluation adjustments of Hudbay's closed site environmental provision.

During the first quarter of 2025, copper equivalent production decreased to 58,611 tonnes as expected, reflecting lower production of copper, gold and silver primarily related to lower planned grades in Peru as the final stripping phase at the Pampacancha deposit was underway. This was partially offset by higher gold production in Manitoba and record average gold prices and high copper prices which positively impacted gross profits.

The Manitoba operations delivered strong quarterly throughput as expected and unlocked better-than-expected grades, resulting in higher production that exceeded Hudbay's quarterly cadence expectations. Strong cost control, a weakening Canadian dollar and meaningful exposure to gold by-product credits resulted in consolidated cash cost^1^ and sustaining cash cost^1^per pound of copper produced, net of by-product credits, in the first quarter of 2025 of $(0.45) and $0.72, respectively, contributing to the increased gross margin and very strong growth in adjusted EBITDA. Higher profits since 2023 in Peru and Canada have resulted in significant cash taxes paid of $117.5 million in the first quarter of 2025, which is reflected in operating cash flow before changes in non-cash working capital. In addition, deleveraging efforts including the repurchases of the Company's senior secured notes over the course of 2024 led to declining net interest cost to service Hudbay's long term debt.

Since acquiring Copper Mountain in June 2023, Hudbay has been executing optimization efforts focused on ramping up the mining fleet to execute a planned accelerated stripping campaign and gain access to higher grades, as well as plant improvement initiatives to improve mill reliability, throughput and recoveries.

During the fourth quarter of 2024, copper equivalent production increased to 77,769 tonnes. Hudbay's Manitoba and Peru operations delivered strong quarterly production as expected and unlocked higher grade helping the Company exceed 2024 annual gold guidance. Strong cost control and meaningful exposure to gold by-product credits resulted in consolidated cash cost^1^ and sustaining cash cost^1^ per pound of copper produced, net of by-product credits^1^, in the fourth quarter of 2024 of $0.45 and $1.37, respectively, contributing to Hudbay's outperformance of its improved full year 2024 cost guidance. Furthermore, the settlement of the gold prepayment liability in the third quarter of 2024, allowed Hudbay to capitalize on surging gold prices. Since acquiring Copper Mountain in June 2023, Hudbay has moved to optimization efforts which have been focused on ramping up the mining fleet to execute a planned accelerated stripping campaign to gain access to higher grades, as well as plant improvement initiatives to improve mill reliability and recoveries.

During the third quarter of 2024, profitability and cash flows grew compared to the second quarter of 2024. This strength was attributable in part to higher gold, copper and zinc production compared to the second quarter of 2024, along with returning strength in commodity prices including record gold prices. These impacts offset planned lower mined grades observed in Peru in the third quarter of 2024 and the higher cash mining taxes paid in Peru resulting from higher profitability over the past several quarters. Strong operating cost control continued into the third quarter of 2024 resulting from a number of operational initiatives and high levels of mill throughput being experienced throughout the business.

During the second quarter of 2024, realized copper and gold prices continued to climb which overcame the decline in sales volumes of concentrate compared to the first quarter of 2024. Expected lower mined grades observed for the same metals in Peru and Manitoba were the primary factor for the decline in production since the first quarter of the year. Cost control remained favourable as Hudbay continued to track within cost guidance given the expected cadence in the year's production profile. Higher mining taxes continued as Hudbay experienced higher profitability over the past several quarters. Lastly, volatile inter-period copper and gold prices led to relatively high mark-to-market adjustments for Hudbay's strategic non-QP hedging program and high share prices for Hudbay's common shares led to higher share-based compensation expenses. This led to a total of $19.5 million in mark-to-market adjustments to be added back in Hudbay's adjusted net earnings - attributable to owners measure.

The first quarter of 2024 and the fourth quarter of 2023 reflected the continuation of strong copper, gold and silver production that commenced in the third quarter of 2023. The increase in copper, gold and silver prices in the first quarter of 2024 also contributed to strong revenue and profitability in the quarter.

Third quarter of 2023 results reflected significantly higher copper and gold production and sales volumes from the high grade zones of the Pampacancha deposit and higher gold and copper grade zones at Lalor resulting in a significant increase in Hudbay's revenues, gross profits and earnings.

The second quarter of 2023 benefited from the drawdown of higher-than-normal unsold copper concentrate inventory levels in Peru that had built up due to supply chain disruptions during a short period of social and political unrest in the first quarter of 2023.

NON-GAAP FINANCIAL PERFORMANCE MEASURES

Adjusted net earnings (loss) attributable to owners, adjusted net earnings (loss) per share attributable to owners, adjusted EBITDA, realized prices, net debt, net debt to adjusted EBITDA, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced, cash cost and sustaining cash cost per ounce of gold produced, combined unit cost and ratios based on these measures are non-GAAP performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of gross profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Management believes adjusted net earnings (loss) attributable to owners and adjusted net earnings (loss) per share attributable to owners provides an alternate measure of the Company's performance for the current period and gives insight into its expected performance in future periods. These measures are used internally by the Company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the Company believes these measures are useful to investors in assessing the Company's underlying performance. Hudbay provides adjusted EBITDA to help users analyze Hudbay's results and to provide additional information about its ongoing cash generating potential in order to assess its capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the Company to assess its financial position. Net debt to adjusted EBITDA is shown because it is a performance measure used by the Company to assess its financial leverage and debt capacity. Realized price is shown to understand the average realized price of metals sold to third parties in each reporting period. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because Hudbay believes they help investors and management assess the performance of its operations, including the margin generated by the operations and the Company. Cash cost and sustaining cash cost per ounce of gold produced are shown because Hudbay believes they help investors and management assess the performance of its Manitoba operations. Combined unit cost is shown because Hudbay believes it helps investors and management assess the cost structure and margins that are not impacted by variability in by-product commodity prices.

Adjusted Net Earnings - Attributable to owners

Adjusted net earnings attributable to owners represents net earnings (loss) excluding certain impacts such as mark-to-market adjustments, foreign exchange (gains) loss, revaluation adjustment - environmental provisions for closed sites, variable consideration adjustment related to stream agreements, impairment charges and reversal of impairment charges on assets, (gain) loss on disposal of assets, other items that are not indicative of the underlying operating performance of Hudbay's core business; and tax effect and non-controlling interest of the previously discussed items. These measures are not necessarily indicative of net earnings (loss) as determined under IFRS. The following table provides a reconciliation of net earnings and non-controlling interest per the condensed consolidated interim statements of income, to adjusted net earnings attributable to owners of the Company for the three months ended March 31, 2025 and December 31, and March 31, 2024.

After adjusting reported net earnings for those items not considered representative of the Company's core business or indicative of future operations, the Company had adjusted net earnings - attributable in the first quarter of 2025 of $93.8 million or 0.24 earnings per share.

Adjusted EBITDA

Adjusted EBITDA is net earnings before net finance expense/income, tax expense/recoveries, depreciation and amortization of property, plant and equipment and deferred revenue, as well as certain other adjustments. Hudbay calculates adjusted EBITDA by excluding certain adjustments included within Hudbay's adjusted net earnings attributable measure which reflects the underlying performance of Hudbay's core operating activities. The measure also removes the impact of non-cash items and financing costs that are not associated with measuring the underlying performance of Hudbay's operations. However, Hudbay's adjusted EBITDA is not the measure defined as EBITDA under Hudbay's senior notes or revolving credit facilities and may not be comparable with performance measures with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for earnings, which is calculated in accordance with IFRS. Hudbay provides adjusted EBITDA to help users analyze their results and to provide additional information about Hudbay's ongoing cash generating potential in order to assess their capacity to service and repay debt, carry out investments and cover working capital needs.

The following table presents the reconciliation of earnings per the condensed consolidated interim statements of income, to adjusted EBITDA for the three months ended March 31, 2025 and December 31, and March 31, 2024:

Cash Cost, Sustaining and All-in Sustaining Cash Cost (Copper Basis)

Cash cost per pound of copper produced ("cash cost") is a non-GAAP measure that management uses as a key performance indicator to assess the performance of its operations. Hudbay's calculation designates copper as the primary metal of production as it has been the largest component of revenues. The calculation is presented in four manners:

  • Cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of copper produced, Hudbay's primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, affected by the relative mix of copper concentrate and zinc concentrate production, where an increase in production of zinc concentrate will tend to result in an increase in cash cost under this measure.

  • Cash cost, net of by-product credits - In order to calculate the net cost to produce and sell copper, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than copper. The by-product revenues from zinc, gold, and silver are significant and are integral to the economics of Hudbay's operations. The economics that support Hudbay's decision to produce and sell copper would be different if Hudbay did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum copper price consistent with positive operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure its operating performance versus that of its competitors. However, it is important to understand that if by-product metal prices decline alongside copper prices, the cash cost net of by-product credits would increase, requiring a higher copper price than that reported to maintain positive cash flows and operating margins.

  • Sustaining cash cost, net of by-product credits - This measure is an extension of cash cost that includes cash sustaining capital expenditures, including payments on capitalized leases, capitalized sustaining exploration, net smelter returns royalties, payments on certain long-term community agreements, as well as accretion and amortization for expected decommissioning activities for producing assets. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than cash cost, which is focused on operating costs only.

- All-in sustaining cash cost, net of by-product credits - This measure is an extension of sustaining cash cost that includes corporate G&A, regional costs, accretion and amortization for community agreements relating to current operations, and accretion for expected decommissioning activities for non-producing sites. Due to the inclusion of corporate selling and administrative expenses, all-in sustaining cash cost is presented on a consolidated basis only.

The tables below present a detailed build-up of cash cost and sustaining cash cost, net of by-product credits, by business unit in addition to consolidated all-in sustaining cash cost, net of by-product credits, and reconciliations between cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three months ended March 31, 2025 and December 31, and March 31, 2024. Cash cost, net of by-product credits may not calculate exactly based on amounts presented in the tables below due to rounding.

Gold Cash Cost and Gold Sustaining Cash Cost

Cash cost per ounce of gold produced ("gold cash cost") is a non-GAAP measure that management uses as a key performance indicator to assess the performance of Hudbay's Manitoba operations. This alternative cash cost calculation designates gold as the primary metal of production as it represents a substantial component of revenues for Hudbay's Manitoba business unit and should therefore be less volatile over time than Manitoba cash cost per pound of copper. The calculation is presented in three manners:

  • Gold cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only ounces of gold produced, the assumed primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals.

  • Gold cash cost, net of by-product credits - In order to calculate the net cost to produce and sell gold, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than gold. The by-product revenues from copper, zinc, and silver are significant and are integral to the economics of Hudbay's Manitoba operation. The economics that support its decision to produce and sell gold would be different if Hudbay did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum gold price consistent with positive operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure Hudbay's operating performance at its Manitoba operation versus that of its competitors. However, it is important to understand that if by-product metal prices decline alongside gold prices, the gold cash cost net of by-product credits would increase, requiring a higher gold price than that reported to maintain positive cash flows and operating margins.

It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than gold cash cost, which is focused on operating costs only.

The tables below present a detailed build-up of gold cash cost and gold sustaining cash cost, net of by-product credits, for the Manitoba business unit, and reconciliations between gold cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three months ended March 31, 2025 and December 31, and March 31, 2024. Gold cash cost, net of by-product credits, may not calculate exactly based on amounts presented in the tables below due to rounding.

Combined Unit Cost

Combined unit cost ("unit cost") and zinc plant unit cost is a non-GAAP measure that management uses as a key performance indicator to assess the performance of Hudbay's mining and milling operations. Combined unit cost is calculated by dividing the cost of sales by mill throughput. This measure is utilized by management and investors to assess Hudbay's cost structure and margins and compare it to similar information provided by other companies in the industry. Unlike cash cost, this measure is not impacted by variability in by-product commodity prices since there are no by-product deductions; costs associated with profit-sharing and similar costs are excluded because of their correlation to external metal prices. In addition, the unit costs are reported in the functional currency of the operation which minimizes the impact of foreign currency fluctuations. In all, the unit cost measures provide an alternative perspective on operating cost performance with minimal impact from external market prices.

The tables below present a detailed combined unit cost for the Peru and Manitoba business units, and reconciliations between these measures to the most comparable IFRS measures of cost of sales for the three months ended March 31, 2025 and December 31, and March 31, 2024.

ACCOUNTING CHANGES AND CRITICAL ESTIMATES

New standards issued but not yet effective

For information on new standards issued but not yet effective, refer to note 3 of Hudbay's March 31, 2025 consolidated interim financial statements.

Estimates and judgements

The preparation of the consolidated interim financial statements in accordance with IFRS requires Hudbay to make judgements, estimates and assumptions that affect the application of accounting policies, reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated interim financial statements, and reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

Hudbay reviews these estimates and underlying assumptions on an ongoing basis based on its experience and other factors, including expectations of future events that Hudbay believes to be reasonable under the circumstances. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Certain accounting estimates and judgements have been identified as being "critical" to the presentation of Hudbay's financial condition and results of operations because they require Hudbay to make subjective and/or complex judgments about matters that are inherently uncertain; or there is a reasonable likelihood that materially different amounts could be reported under different conditions or using different assumptions and estimates.

For more information on judgements and estimates, refer to note 2 of Hudbay's March 31, 2025 consolidated interim financial statements.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting ("ICFR"). ICFR is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated interim financial statements for external purposes in accordance with IFRS.

Hudbay did not make any changes to ICFR during the three months ended March 31, 2025 that materially affected or are reasonably likely to materially affect Hudbay's ICFR.

Hudbay Delivers Strong First Quarter 2025 Results Driven by Gold Production and Record Cost Performance

Toronto, Ontario, May 12, 2025 - Hudbay Minerals Inc. ("Hudbay" or the "Company") (TSX, NYSE: HBM) today released its first quarter 2025 financial results. All amounts are in U.S. dollars, unless otherwise noted.

"Our strong results in the first quarter reflect stable copper production and complementary gold production from our enhanced operating platform, which continued to deliver significant free cash flows and industry-leading margins," said Peter Kukielski, President and Chief Executive Officer. "We are well-positioned to deliver our full year 2025 consolidated production and cost guidance with the operations delivering in line copper production, better-than-expected gold production and effective cost control in the first quarter. We continue to benefit from steady mill throughput in Peru, higher grades and mill throughput in Manitoba and ongoing optimization efforts in British Columbia. This resulted in record adjusted EBITDA and record low cash cost performance in the quarter. We made significant progress in advancing our growth strategy as we consolidated ownership at Copper Mountain to increase our exposure to a high-quality asset in a tier-1 jurisdiction. We are also now fully permitted at Copper World to increase our long-term copper production by more than 50%. We will continue to reinvest in our attractive portfolio of high-return brownfield and greenfield growth opportunities to further enhance our copper and gold exposure and unlock significant value for all our stakeholders."

Achieved Record Adjusted EBITDA Driven by Strong Gold Production, Stable Copper Production and Industry-leading Margins; 2025 Production and Cost Guidance Reaffirmed

  • Achieved revenue of $594.9 million and record quarterly adjusted EBITDA^i^ of $287.2 million in the first quarter of 2025.
  • Strong financial results were driven by record low consolidated cash cost performance as all three business units expanded operating cost margins and executed on planned strategies.
  • Consolidated copper production of 30,958 tonnes in the first quarter was in line with quarterly cadence expectations. Consolidated gold production of 73,784 ounces was better than quarterly cadence expectations driven by outperformance in Manitoba.
  • Industry-leading cost performance continues with record low consolidated cash cost^i^ and sustaining cash cost^i^ per pound of copper produced, net of by-product credits, of $(0.45) and $0.72, respectively, in the quarter.
  • Reaffirmed full year 2025 consolidated production guidance of 117,000 to 149,000 tonnes of copper and 247,500 to 308,000 ounces of gold. Reaffirmed all 2025 cost guidance, including consolidated cash cost^i^ guidance of $0.80 to $1.00 per pound of copper and sustaining cash cost^i^ guidance of $2.25 to $2.65 per pound of copper.
  • Peru operations continued to benefit from strong and consistent mill throughput, achieving an average of approximately 90,200 tonnes per day in the first quarter. Copper production of 20,293 tonnes and gold production of 7,869 ounces was in line with quarterly cadence expectations. Peru cash cost^i^ per pound of copper produced, net of by-product credits, of $1.11 was better than expected as the Peru operations demonstrated strong cost control and benefited from higher by-product prices.
TSX, NYSE - HBM<br><br> <br>2025 No. 14
  • Manitoba operations produced 60,354 ounces of gold in the first quarter, exceeding quarterly cadence expectations as a result of better-than-expected gold grades and recoveries. Manitoba cash cost^i^ per ounce of gold produced, net of by-product credits, was $376 during the quarter, a significant decrease compared to prior quarters and continuing to achieve industry-leading cost performance.
  • British Columbia operations produced 7,196 tonnes of copper at a cash cost^i^ per pound of copper produced, net of by-product credits, of $2.44 in the first quarter, in line with quarterly cadence expectations.
  • First quarter net earnings attributable to owners and earnings per share attributable to owners were $100.4 million and $0.25, respectively, a significant increase compared to the first and fourth quarter of 2024, driven by high gross margins with strong revenue and unit cost control. After adjusting for various non-cash items, first quarter adjusted earnings^i^ per share attributable to owners was $0.24.
  • Cash and cash equivalents and short-term investments were $582.6 million and total liquidity was $1,008.5 million at the end of the first quarter of 2025.

Summary of First Quarter Results

Consolidated copper production of 30,958 tonnes in the first quarter of 2025 was in line with quarterly production cadence expectations, while consolidated gold production of 73,784 ounces was better than quarterly production cadence expectations. Consolidated copper and gold production was lower than the fourth quarter of 2024 due to lower planned grades in Peru as Hudbay is completing the final stripping phase in the high-grade Pampacancha pit, partially offset by higher gold production in Manitoba from better-than-expected gold grades. Consolidated silver production of 919,775 ounces and zinc production of 6,265 tonnes in the first quarter of 2025 were lower than the fourth quarter of 2024 primarily due to lower grades in Peru as the Company completed planned stripping activities.

Cash generated from operating activities of $124.8 million decreased compared to the fourth quarter of 2024 as a result of higher cash taxes paid which are a function of higher profits in earlier quarters in Peru and Manitoba. Operating cash flow before change in non-cash working capital was $163.5 million during the first quarter of 2025, reflecting a decrease of $68 million compared to the fourth quarter of 2024. The decrease was primarily the result of lower gold and copper sales volumes in Peru as expected.

First quarter adjusted EBITDA^i^ was $287.2 million, a 12% increase compared to $257.3 million in the fourth quarter of 2024 as exposure to higher copper and gold prices in the quarter offset the lower sales volume.

Net earnings attributable to owners in the first quarter of 2025 was $100.4 million, or $0.25 per share, compared to $21.2 million, or $0.05 per share, in the fourth quarter of 2024. The significant increase in earnings is the result of high gross margins from strong revenue growth on the back of higher realized copper and gold prices and strong unit cost control. In addition to higher mining and income tax expense experienced in the first quarter of 2025, the quarter was also impacted by various non-cash charges for revaluation loss of closed sites reclamation provisions, mark-to-market revaluation gain on various instruments, and foreign exchange gain, among other items.

TSX, NYSE - HBM<br><br> <br>2025 No. 14

Adjusted net earnings attributable to owners^i^ and adjusted net earnings per share attributable to owners^i^ in the first quarter of 2025 were $93.8 million and $0.24 per share, respectively, after adjusting for various non-cash items on a pre-tax basis such as a non-cash loss of $12.8 million related to quarterly revaluation of Hudbay's closed site environmental reclamation provision, a $10.5 million variable consideration adjustment gain associated with the stream revenue and accretion, a $3.1 million mark-to-market revaluation gain on various instruments such as unrealized strategic copper hedges, investments and share-based compensation, a non-cash $3.1 million foreign exchange gain, and a $1.9 million gain related to flow-through share expenditures, among other items. This compares to adjusted net earnings attributable to owners^i^ and net earnings per share attributable to owners^i^ of $70.3 million and $0.18 per share in the fourth quarter of 2024. The sharp increase in adjusted net earnings attributable to owners^i^ and adjusted net earnings per share attributable to owners^i^ is for the same reasons discussed above for net earnings.

In the first quarter of 2025, consolidated cash cost^i^ per pound of copper produced, net of by-product credits, achieved record low levels of $(0.45), compared to $0.45 in the fourth quarter of 2024. This improvement was a result of higher by-product credits and strong operating cost performance across all business units, partially offset by expected lower production levels in Peru during the quarter. Consolidated sustaining cash cost^i^ per pound of copper produced, net of by-product credits, was a record low at $0.72 in the first quarter of 2025, compared to $1.37 in the fourth quarter of 2024. The improvement was driven by the same factors impacting consolidated cash cost and slightly lower sustaining capital expenditures in the first quarter. Consolidated all-in sustaining cash cost^i^ per pound of copper produced, net of by-product credits, was $0.97 in the first quarter of 2025, lower than $1.53 in the fourth quarter of 2024 mainly due to the same reason outlined above.

As at March 31, 2025, total liquidity was $1,008.5 million, including $562.6 million in cash and cash equivalents, $20.0 million in short-term investments as well as undrawn availability of $425.9 million under the Company's revolving credit facilities. Net debt^i^ at the end of the first quarter was $526.1 million and remained consistent with the fourth quarter of 2024.

During the first quarter of 2025, the Peru operations produced 20,293 tonnes of copper, 7,869 ounces of gold, 554,692 ounces of silver and 397 tonnes of molybdenum, in line with mine plan quarterly cadence expectations. Production of copper, gold and silver in the first quarter of 2025 was lower than the fourth quarter of 2024 due to planned lower grades as a larger portion of lower grade Constancia ore was processed in the current quarter. Hudbay is on track to achieve its 2025 production guidance for all metals in Peru.

TSX, NYSE - HBM<br><br> <br>2025 No. 14

Copper production was in line with mine plan expectations as the final phase of planned stripping at the Pampacancha deposit was underway during the first quarter of 2025. This resulted in planned lower head grades to the mill as Constancia ore represented a majority of the ore feed during the first quarter of 2025. Peru operations continued to benefit from strong and consistent mill throughput in 2025, averaging approximately 90,200 tonnes processed per day in the first quarter of 2025, partially offsetting the planned lower head grades. The operations continued to deliver strong cost control, resulting in lower combined unit cost compared to the fourth quarter of 2024.

Total ore mined in the first quarter of 2025 increased by 10% compared to the fourth quarter of 2024. Ore mined from Pampacancha during the first quarter of 2025 decreased to 0.4 million tonnes, as Hudbay is performing the final stripping phase in the Pampacancha pit prior to depletion in late 2025. Ore mined from Constancia significantly increased during the first quarter of 2025 compared to recent quarters, in line with mine plan expectations.

Milled copper and gold grades decreased by 38% and 75%, respectively, in the first quarter of 2025 compared to the fourth quarter of 2024, in line with the mine plan due to planned lower ore feed from Pampacancha. The Constancia mill achieved copper recoveries of 85% in the first quarter of 2025, lower than the fourth quarter of 2024 due to planned lower grades. Recoveries of gold and silver during the first quarter of 2025 were 57% and 66%, respectively, remaining in line with Hudbay's metallurgical models for the ore types that were being processed.

Combined mine, mill and G&A unit operating cost^i^ in the first quarter of 2025 was $11.09 per tonne, 27% lower than the fourth quarter of 2024 due to a planned semi-annual mill maintenance shutdown in the fourth quarter and lower overall onsite costs.

Cash cost^i^ per pound of copper produced, net of by-product credits, in the first quarter of 2025 was $1.11, outperforming quarterly cadence expectations as a result of strong operating cost performances and higher by-product prices. Cash cost^i^ per pound of copper produced, net of by-product credits was higher than the fourth quarter of 2024 due to planned lower copper production and gold by-product credits, partially offset by lower treatment, refining and freight charges. Cash cost^i^ for the quarter outperformed the low-end of the 2025 guidance range, and Hudbay is well positioned to achieve the full year 2025 cash cost guidance range in Peru.

Sustaining cash cost^i^ per pound of copper produced, net of by-product credits, was $1.92 in the first quarter of 2025, an increase compared to the fourth quarter of 2024 primarily due to the same factors described above for the cash cost variance.

The Company continues to evaluate opportunities to further increase mill throughput after the Peruvian Ministry of Energy and Mines approved a regulatory change in 2024 to allow mining companies in Peru to increase throughput by up to 10% above permitted levels. Hudbay is advancing engineering studies for the construction of a pebble crusher at Constancia commencing in late 2025, which is expected to further increase throughput levels starting in the second half of 2026.

The Manitoba operations achieved impressive metal production and cost performance in the first quarter of 2025, significantly exceeding budgeted targets. The operations produced 60,354 ounces of gold, 3,469 tonnes of copper, 6,265 tonnes of zinc and 285,603 ounces of silver during the first quarter of 2025. Compared to the fourth quarter of 2024, production of gold meaningfully increased by 17% due to higher grades. Hudbay is on track to achieve its 2025 production guidance for all metals in Manitoba.

The Lalor mine achieved strong production results in the first quarter, averaging 4,300 tonnes per day, demonstrating resilience despite one-off ore handling challenges in March. The mine maintained focus on ore quality, implementing stope modifications and improving mucking productivity rates. A significant focus is on capital development, aimed at securing high-grade copper-gold mineralization from Zone 27 and preparing for the next copper-gold mining front in Zone 17. The first quarter of 2025 saw significant improvements in ore quality, aligned with improvements in mining techniques, most notably in longhole muck fragmentation, and anticipated higher grade precious metal sequences.

Total ore mined in Manitoba in the first quarter of 2025 was 6% lower than the fourth quarter of 2024 primarily due to temporary ore handling challenges at Lalor in March that were promptly resolved. Gold grades were better than expected, resulting in an 18% increase from the fourth quarter of 2024. Copper, zinc and silver grades were in line with mine plan expectations.

The New Britannia mill continued its exceptional performance from recent quarters, achieving throughput of approximately 2,100 tonnes per day in the first quarter of 2025, slightly higher than the fourth quarter of 2024. New elongated cyclones were installed at New Britannia during the first quarter, mirroring successful upgrades at the Stall mill, and supporting Hudbay's strategy of low-capital projects to boost throughput and maintain gold recoveries. Gold recovery in the first quarter of 2025 was 90%, in line with the fourth quarter of 2024.

At the Stall mill, a slight quarter-over-quarter reduction in throughput occurred as more ore was diverted to New Britannia in the first quarter. The Stall mill achieved gold recoveries of 70% in the first quarter of 2025, benefitting from recent recovery improvement programs continuing to be realized, with gold recoveries exceeding prior year figures. Efforts continue to optimize recovery, particularly by reducing grind size.

The Manitoba operations continued to drive operating efficiencies, resulting in improved cost performance on both a unit operating basis and on a cash cost basis. Combined mine, mill and G&A unit operating costs^i^ in the first quarter of 2025 were C$214 per tonne, representing an 8% decrease from the fourth quarter of 2024, primarily due to lower mine and mill costs.

Cash cost^i^ per ounce of gold produced, net of by-product credits, in the first quarter of 2025 was $376, a significant 38% decrease compared to the fourth quarter of 2024 primarily due to higher gold production and lower mining and milling costs as a result of continued operating efficiencies and favorable exchange rates. With first quarter cash costs outperforming the low end of the cash cost guidance range, Hudbay is well positioned to achieve the 2025 cash cost guidance range in Manitoba.

Sustaining cash cost^i^ per ounce of gold produced, net of by-product credits, in the first quarter of 2025 was $626, a 31% decrease compared to the fourth quarter of 2024, primarily due to the same factors affecting cash cost, partially offset by higher sustaining capital costs during the quarter.

The exploration and haulage drifts at 1901 maintained solid development progress towards the deposit in the first quarter of 2025. A recent drill hole from the exploration drift intersected zinc-rich massive sulphides 20 metres earlier than anticipated, confirming planned first ore in the second quarter of 2025. The next two years will focus on exploration, definition drilling, orebody access, and establishing critical infrastructure for full production in 2027.

Hudbay continues its focus on advancing optimization plans at the Copper Mountain mine, including opening up and optimizing the mine ore feed to the plant and implementing plant improvement initiatives that mirror Hudbay's successful processes at Constancia. These optimization initiatives have successfully increased the total tonnes moved and improved mill reliability.  The British Columbia operations produced 7,196 tonnes of copper, 5,561 ounces of gold and 79,480 ounces of silver in the first quarter of 2025. Production of copper, gold and silver increased by 21%, 20% and 35%, respectively, compared to the fourth quarter of 2024, largely due to higher grades. Hudbay is on track to achieve its 2025 production guidance for all metals in British Columbia and continues to expect higher production in the second half of the year as the mill improvement projects take effect.

Mining activities are focused on continuing to execute the three-year accelerated stripping program intended to bring higher grade ore into the mine plan. In January, Hudbay completed feasibility engineering to debottleneck and increase the nominal plant capacity to its permitted capacity of 50,000 tonnes per day earlier than contemplated in the most recent technical report. This is expected to be achieved through the conversion of the third ball mill to a second SAG mill, which remains on track for completion in the second half of 2025.

TSX, NYSE - HBM<br><br> <br>2025 No. 14

Total ore mined at Copper Mountain in the first quarter of 2025 was 2.6 million tonnes, a 12% increase compared to the fourth quarter of 2024. Total material moved continued to ramp up in the quarter as a result of effective usage of the mining fleet to execute the accelerated stripping program to access higher head grades. The focus in the first quarter of 2025 was on mining efficiencies and operator recruitment to effectively utilize the available haul truck fleet. As a result, total material moved is expected to increase quarter-over-quarter in 2025 as per the mine plan.

The mill processed 2.8 million tonnes of ore during the first quarter of 2025. Ore processed in the first quarter of 2025 was lower than the fourth quarter of 2024, limited by both planned and unplanned maintenance and elevated clay material last quarter which impacted the secondary crushing circuit. In the first quarter of 2025, a number of initiatives were advanced to address these issues and other identified constraints to improve throughput. Several mill initiatives have been implemented in 2025, including crushing circuit chute modifications, recovery improvements, reprogramming the mill expert system, installation of advanced semi-autogenous grinding control instrumentation, redesigned SAG liner package and updated operational procedures intended to remove magnetite from the pebble stream. Progressive improvements are expected to continue through 2025.

Milled copper grades during the first quarter of 2025 were 27% higher than in the fourth quarter of 2024. The accelerated stripping efforts unlocked a higher-grade mining sequence during the first quarter of 2025, which reduced the amount of ore processed from stockpiles and resulted in higher grades this quarter compared to 2024. Copper recoveries of 78% in the quarter were 2% lower than the preceding quarter. Milled gold grades were higher in the first quarter of 2025 compared to the fourth quarter of 2024, resulting in higher gold recoveries of 63% in the first quarter of 2025.

Combined mine, mill and G&A unit operating costs^i^ in the first quarter of 2025 were C$25.98 per tonne milled, higher than the fourth quarter of 2024. The increase was due to higher mining and G&A costs and lower ore milled, partially offset by lower milling costs.

Cash cost^i^ and sustaining cash cost^i^ per pound of copper produced, net of by-product credits, in the first quarter of 2025 were $2.44 and $4.24, respectively. Cash costs were 19% lower than the fourth quarter of 2024, largely due to higher by-product credits and the benefit from the continued focus on optimization efforts. With first quarter cash cost at the low-end of the 2025 guidance range, Hudbay is well positioned to achieve the full year 2025 cash cost guidance range in British Columbia.

Sustaining cash costs^i^ were 26% lower than in the fourth quarter of 2024 due to the same factors affecting cash costs as well as lower sustaining capital expenditures.

Consolidated 100% Ownership in Copper Mountain

On March 27, 2025, Hudbay announced an agreement with Mitsubishi Materials Corporation ("MMC") to acquire MMC's 25% minority interest in Copper Mountain for an upfront cash payment of $4.5 million and up to $39.75 million in deferred and contingent cash payments. The transaction closed on April 30, 2025 and Hudbay now holds a 100% interest in the Copper Mountain mine. In connection with the transaction, Hudbay is solely responsible to settle any of Copper Mountain's outstanding obligations, including an intercompany loan owing to Hudbay, of which 25% represents approximately $104 million. The transaction is highly accretive to Hudbay's net asset value per share and increases Hudbay's exposure to a long-life, high-quality copper asset in a tier-1 mining jurisdiction. The additional attributable production from the Copper Mountain mine reinforces Hudbay's position as the second largest copper producer in Canada and further strengthens its position as a North American copper champion. Hudbay has initiated a review of its Canadian corporate structure which is anticipated to generate tax synergies through the sharing of tax pools between its various Canadian entities.

TSX, NYSE - HBM<br><br> <br>2025 No. 14

Continued Free Cash Flow Generation from Steady Operating Performance and Strong Copper and Gold Exposure

Hudbay has delivered seven consecutive quarters of meaningful free cash flow^vii^ generation as a result of brownfield investments, continuous operational improvement efforts and steady cost control across the business. Over the last twelve months, the Company has generated more than $350 million in free cash flow^vii^ and $895.7 million in adjusted EBITDA^i^.

While a majority of revenues continue to be derived from copper production, gold continues to represent more than 35% of total revenues. The unique copper and gold diversification is derived from copper and gold production in Peru, gold production from Manitoba and copper production contribution from British Columbia. The diversified and stable operating platform provides significant exposure to higher copper and gold prices. Using the mid-point of Hudbay's 2025 guidance ranges, a 10% increase in annual copper and gold prices would increase operating cash flow by $100 million and $56 million, respectively, as disclosed with Hudbay's 2025 guidance announcement in February^ii^.

During the first quarter of 2025, the Company invested $25.5 million in growth capital expenditures relating to advancing high-return brownfield mill initiatives and greenfield copper projects to drive near-term and long-term production growth. Hudbay's balance sheet is well positioned to continue to advance its several growth initiatives. Net debt^i^ of $526.1 million in the first quarter of 2025 remained consistent with the fourth quarter of 2024 and reflects the deleveraging efforts completed in 2024. Hudbay's net debt to adjusted EBITDA ratio^i^ was 0.6x in the first quarter of 2025, in line with the fourth quarter of 2024 and significantly improved from 1.3x in the first quarter of 2024 because of successful deleveraging efforts throughout 2024.

Annual Reserve and Resource Update and Three-Year Production Guidance

Hudbay provided its annual mineral reserve and resource update and issued new three-year production guidance on March 27, 2025.

In Peru, current mineral reserve estimates total 517 million tonnes at 0.25% copper containing approximately 1.3 million tonnes of copper. In 2024, the Company increased mineral reserve estimates at Constancia to include the addition of a tenth mining phase in the Constancia pit after conducting positive geotechnical drilling and studies in 2023. This extended the expected mine life at Constancia by three years to 2041. Mining at the high-grade Pampacancha satellite pit commenced in 2021 and is expected to extend until early December 2025. The mine plan has smoothed Pampacancha production throughout 2025, resulting in total mill ore feed for 2025 from Pampacancha to be ~25%, lower than the typical one-third in prior years. Annual production at the Constancia operations is expected to average approximately 88,000^iii^ tonnes of copper and 31,000^iii^ ounces of gold over the next three years. This reflects steady copper production levels as higher mill throughput is expected to offset lower grades starting in 2026 after the depletion of Pampacancha in late 2025.

In Snow Lake, the current mineral reserve estimates a total of approximately 16 million tonnes with approximately 1.7 million ounces in contained gold and an expected mine life to 2037. Snow Lake's life-of-mine production schedule has been optimized for higher mill throughput rates at New Britannia, maximizing gold production and cash flows. In 2024, record annual gold production of 214,225 ounces was achieved in Snow Lake through a combination of higher metallurgical recoveries at the New Britannia and Stall mills, despite processing lower gold grades year-over-year, and the strategic allocation of more gold ore feed to the New Britannia mill. Annual gold production from Snow Lake is expected to average more than 193,000^iii^ ounces over the next three years. The impressive operating performance has resulted in 2025 gold production guidance being 8% higher than the previous 2025 guidance of 185,000^iii^ ounces, and 2026 gold production guidance being 3% higher than the previous 2026 guidance of 185,000^iii^ ounces. Similarly, the midpoint of the 2027 gold production guidance is 17% higher than the anticipated 2027 production in the most recent technical report.

TSX, NYSE - HBM<br><br> <br>2025 No. 14

In British Columbia, current mineral reserve estimates at Copper Mountain total 346 million tonnes at 0.25% copper and 0.12 grams per tonne gold with approximately 850 thousand tonnes of contained copper and 1.3 million ounces of contained gold. The current mineral reserve estimates continue to support mine life until 2043, with significant upside potential for future resource conversion and mine life extension beyond 19 years through an additional 125 million tonnes of measured and indicated resources at 0.21% copper and 0.10 grams per tonne gold and 372 million tonnes of inferred resources at 0.25% copper and 0.13 grams per tonne gold, in each case, exclusive of mineral reserves. In 2025, the planned conversion of the third ball mill to a second SAG mill is anticipated to result in the ramp-up of mill throughput in the second half of the year. The mill throughput is anticipated to ramp up towards 50,000 tonnes per day in 2026. Annual production at the British Columbia operations is expected to average approximately 44,000^iii^ tonnes of copper and 28,600^iii^ ounces of gold over the next three years. Upon completion of Hudbay's optimization activities, 2027 copper production is expected to be 60,000^iii^ tonnes, representing a 127% increase from 2024. 2027 expected copper production is also 20% higher than the production in the most recent technical report as a result of the deferral of higher grades from 2026 to 2027 in connection with the current accelerated stripping schedule.

Consolidated copper production over the next three years is expected to average 144,000^iii^ tonnes, representing an increase of 4% from 2024 levels. The increase is due to higher expected copper production in British Columbia as a result of mill throughput ramp-up throughout 2025 and 2026 and higher grades in 2027 from the accelerated stripping schedule, which more than offsets the depletion of the high-grade Pampacancha deposit in Peru at the end of 2025. Consolidated gold production over the next three years is expected to average 253,000^iii^ ounces, reflecting higher-than-expected annual gold production levels in Manitoba, as compared to prior guidance, a result of continued strong operating performance in Snow Lake.

Advancing Copper World Towards a Sanction Decision

Hudbay received the final major permit required for the development and operation of Copper World in January 2025, and the Company has since commenced a minority joint venture partner process. It is anticipated that any minority joint venture partner would participate in the funding of definitive feasibility study activities as well as the final project design and construction for Copper World. The Company has commenced work to support the definitive feasibility study and progress the project towards a potential sanction decision in 2026.

Copper World is expected to produce 85,000 tonnes of copper per year over an initial 20-year mine life, and the project generates an after-tax net present value ("NPV") (8%) of $1.7 billion with an internal rate of return ("IRR") of 25.5% using a copper price of $4.25 per pound. Copper World is one of the highest-grade open pit copper projects in the Americas^v^ with proven and probable mineral reserves of 385 million tonnes at 0.54% copper. There remains approximately 60% of the total copper contained in measured and indicated mineral resources (exclusive of mineral reserves), providing significant potential for future expansion and mine life extension. Once in production, Copper World is expected to be a meaningful copper producer in the U.S. domestic copper supply chain, which will help secure growing U.S. metal demand related to increased manufacturing capacity, infrastructure development, increased energy independence, domestic battery supply chain and strengthening the nation's security.

Enhancing Stakeholder Relationships at Mason

Hudbay's Mason project in Nevada is one of the largest undeveloped copper porphyry deposits in North America. Based on a preliminary economic assessment ("PEA") completed in 2021^iv^, Mason has the potential to be the third largest copper mine in the U.S. once in operation. The PEA contemplates a 27-year mine life with average annual copper production of approximately 140,000 tonnes over the first ten years of full production. Hudbay continues to advance local stakeholder engagement as well as additional metallurgical studies. While Mason is not as advanced as Copper World, Mason represents a long-term future development asset as part of Hudbay's pipeline of high-quality copper growth opportunities.

Exploration Update

Large Snow Lake Exploration Program Continues to Execute Threefold Strategy

Hudbay continues to execute the largest exploration program in Snow Lake in the Company's history through extensive geophysical surveying and multi-phased drilling campaigns as part of Hudbay's threefold exploration strategy:

• Near-mine exploration at Lalor and 1901 further increase near-term production and extend mine life - Positive initial step out drilling from the exploration drift at the 1901 deposit intersected significant copper-gold mineralization, including 14.3% copper over 2.5 metres and 8.3 grams per tonne gold over 3.2 metres. Additional exploration at 1901 is planned for 2025 targeting additional step-out drill holes to potentially extend the ore body and infill drilling to convert inferred mineral resources in the gold lenses to mineral reserves. Follow up drilling at Lalor Northwest continued to intersect copper-gold mineralization, including 16.4 grams per tonne gold over 3.7 metres and 2.6% copper over 3.5 metres^vi^. Hudbay continues to drill Lalor down-plunge and Lalor Northwest in 2025 through a surface drill program that is focused on testing the extent of the mineralization.

• Testing regional satellite deposits to utilize available processing capacity and increase production - Hudbay increased its land package by more than 250% in 2023 through the acquisition of Rockcliff Metals Corp. ("Rockcliff"), which included the addition of several known deposits located within trucking distance of the Snow Lake processing infrastructure. These newly acquired deposits, together with several deposits already owned by Hudbay in Snow Lake, have created an attractive portfolio of regional deposits in Snow Lake, including the Talbot, Rail, Pen II, Watts, 3 Zone and WIM deposits. The continued strong performance from the New Britannia mill operating at above 2,000 tonnes per day has freed up processing capacity at the Stall mill. There is approximately 1,500 tonnes per day of available capacity at the Stall mill which can be utilized by the regional satellite deposits to increase production and extend the life of the Snow Lake operations beyond 2037.

• Exploring large land package for new anchor deposit to significantly extend mine life - A majority of the newly acquired land claims have been untested by modern deep geophysics, which was the discovery method for the Lalor deposit. A large geophysics program is currently underway consisting of surface electromagnetic surveys using cutting-edge techniques that enable the team to detect targets at depths of almost 1,000 metres below surface. The planned geophysics program in 2025 is the largest geophysics program in Hudbay's history and includes 800 kilometres of ground electromagnetic surveys and an extensive airborne geophysics survey.

Signed Exploration Agreement with First Nations in Manitoba

Hudbay is proud to have reached exploration agreements with two First Nations groups in Manitoba in 2025:

• Kiciwapa Cree Nation - In February 2025, Hudbay signed its first-ever exploration agreement with the Kiciwapa Cree Nation, reflecting the Company's commitment to meaningful collaboration as Hudbay explores new mineral resources in the Snow Lake and Flin Flon regions.

• Mosakahiken Cree Nation - In April 2025, Hudbay signed an exploration agreement with the Mosakahiken Cree Nation, marking a significant step towards building a relationship based on alignment and transparency on its projects in the region, including the Talbot copper-zinc-gold deposit south of Snow Lake. The signing of this agreement represents a compelling opportunity for Hudbay to enhance future production and extend mine life at its Snow Lake operations through additional exploration activities in the region. A large exploration program at Talbot is planned for this summer.

Unlocking Value through Flin Flon Tailings Reprocessing

Hudbay continues to advance studies to evaluate the opportunity to reprocess Flin Flon tailings where more than 100 million tonnes of tailings have been deposited for over 90 years from the mill and the zinc plant. The studies are evaluating the potential to use the existing Flin Flon concentrator, which is currently on care and maintenance after the closure of the 777 mine in 2022, with flow sheet modifications to reprocess tailings to recover critical minerals and precious metals in an environmentally-friendly manner. The more advanced opportunity relates to the zinc plant tailings where metallurgical test work continues following positive results from the initial confirmatory drill program completed in 2024. The results confirmed the grades of precious metals and critical minerals previously estimated from historical zinc plant records. An early economic study to evaluate the opportunity to reprocess the zinc plant tailings has confirmed the potential for a technically viable reprocessing alternative, and the Company is progressing with further engineering work.

Maria Reyna and Caballito Drill Permits Proceeding Through the Regulatory Process

Hudbay controls a large, contiguous block of mineral rights with the potential to host satellite mineral deposits in close proximity to the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna property. The Company commenced the drill permitting process at Maria Reyna and Caballito after completing a surface rights exploration agreement with the community of Uchucarcco in August 2022. As part of the drill permitting process, environmental impact assessment (EIA) applications were approved by the government in June 2024 for Maria Reyna and September 2024 for Caballito. This represents one of several steps in the drill permitting process, and the government is targeting completion of the process in 2025.

Normal Course Issuer Bid

Hudbay's board of directors has approved, subject to the approval of the Toronto Stock Exchange (the "TSX"), a normal course issuer bid ("NCIB") for up to 5% of the Company's issued and outstanding common shares ("Shares"). The NCIB will be conducted in accordance with the requirements of the TSX and applicable securities laws, with purchases to be made as appropriate opportunities arise from time to time.

If the NCIB is approved by the TSX, Hudbay will be authorized to acquire up to a maximum of 5% of its issued and outstanding Shares, for cancellation over a period of 12 months. The actual number of Shares which may be purchased by Hudbay pursuant to the NCIB and the timing of such purchases will be determined by management of the Company and will be subject to a number of factors, including market conditions, share price, available cash resources and other opportunities to invest capital for growth.

Purchases under the NCIB will be made through the facilities of the TSX, New York Stock Exchange, or through alternative Canadian trading systems and in accordance with applicable regulatory requirements at a price per Share equal to the market price at the time of acquisition. Any Shares purchased under the NCIB will be cancelled upon their purchase. Hudbay intends to fund the purchases from its cash flow from operations.

Hudbay has elected to implement the NCIB because it believes that, from time to time, the market price of the Shares may not fully reflect the underlying value of Hudbay's business and future prospects. Hudbay believes that, at such times, the repurchase of the Shares for cancellation may constitute a desirable use of capital and would be in the best interests of shareholders.

Non-GAAP Financial Performance Measures

Adjusted net earnings (loss) attributable to owners, adjusted net earnings (loss) per share attributable to owners, adjusted EBITDA, net debt, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced, cash cost and sustaining cash cost per ounce of gold produced, combined unit cost and ratios based on these measures are non-GAAP performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Management believes adjusted net earnings (loss) attributable to owners and adjusted net earnings (loss) per share attributable to owners provides an alternate measure of the Company's performance for the current period and gives insight into its expected performance in future periods. These measures are used internally by the Company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the Company believes these measures are useful to investors in assessing the Company's underlying performance. Hudbay provides adjusted EBITDA to help users analyze the Company's results and to provide additional information about its ongoing cash generating potential in order to assess its capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the Company to assess its financial position. Net debt to adjusted EBITDA is shown because it is a performance measure used by the Company to assess its financial leverage and debt capacity. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because the Company believes they help investors and management assess the performance of its operations, including the margin generated by the operations and the Company. Cash cost and sustaining cash cost per ounce of gold produced are shown because the Company believes they help investors and management assess the performance of its Manitoba operations. Combined unit cost is shown because Hudbay believes it helps investors and management assess the Company's cost structure and margins that are not impacted by variability in by-product commodity prices.
