Key Terms

adjusted ebitda, free cash flow, net present value, internal rate of return

4 terms

adjusted ebitda financial

"quarterly adjusted EBITDAi of $413.4 million"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

free cash flow financial

"Delivered free cash flowi generation of $201.9 million"

Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.

View in glossary

net present value financial

"after-tax net present value (8%) of $1.2 billion"

Net present value is a way to measure the value of a future amount of money today. It considers how money available in the future is worth less than money now because of potential earning opportunities or inflation. Investors use it to decide whether an investment is worthwhile, aiming for projects with positive net present value, meaning they are expected to generate more value than they cost.

internal rate of return financial

"internal rate of return of 17%"

A percentage that represents the annualized yield an investment would earn, taking into account the timing and amount of all cash inflows and outflows; mathematically it is the rate that makes the discounted sum of future cash flows equal the initial cost. Investors use it to compare different projects or deals the way they compare interest rates — a higher internal rate of return suggests a stronger potential payoff, but it does not by itself show risk, scale, or timing nuances.

TORONTO, Nov. 12, 2026 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. (“Hudbay” or the “Company”) (TSX, NYSE: HBM) released its third quarter 2026 financial results today. All amounts are in U.S. dollars, unless otherwise noted.

“Hudbay delivered record performance this quarter, with revenue of $766 million achieving a new record and adjusted EBITDAⁱ of $413 million resulting in record trailing twelve-month adjusted EBITDA of $1.5 billion, and we are well on our way to delivering the 12^th consecutive year of achieving annual consolidated copper production guidance and the 6^th consecutive year of achieving annual consolidated gold production guidance,” said Peter Kukielski, Chief Executive Officer. “The strength of our diversified operating platform and the dedication of our people helped to achieve a new record for mill throughput at Constancia, significant increases in mine productivity at Lalor, record mill throughput at New Britannia and record gold recoveries at Stall during the third quarter. Our three-year operational turnaround at Copper Mountain has delivered the first quarter of positive free cash flowⁱ since our acquisition. We are extremely well positioned to continue to prudently reinvest in several high-return growth opportunities across the business to further enhance our exposure to copper and gold. Following the quarter, Hudbay and Mitsubishi achieved a significant milestone with the final investment decision at Copper World, one of the best copper growth projects in the Americas, offering some of the highest copper grades, lowest cash costs and favourable capital intensity. We continue to solidify our position as a premier Americas-focused copper producer with a pipeline of long-life, low-cost assets in tier-one jurisdictions.”

“Our diversified operations in Canada and Peru continued to achieve strong copper and gold production, with operating efficiencies, which have more than offset external cost pressures and allowed us to improve our 2026 full-year consolidated cash cost guidance for a second time this year and also improve our 2026 full-year sustaining cash cost guidance,” said Eugene Lei, President and Chief Financial Officer. “We generated over $200 million in free cash flow during this quarter and more than $400 million year-to-date, even after investing over $325 million in sustaining capital across our operations. Our strong free cash flow generation and balance sheet strength position us well to fund our share of the Copper World project and make generational investments in our operating mines to double our copper production per share. This is consistent with our disciplined capital allocation framework, which focuses on generating the highest risk-adjusted returns while advancing our industry-leading growth pipeline.”

Delivered Record Third Quarter Results; Production Guidance Reaffirmed and Cost Guidance Further Improved

• Achieved record quarterly revenue of $765.9 million, net earnings attributable to ownersⁱ of $149.5 million, and quarterly adjusted EBITDAⁱ of $413.4 million, driven by steady operating performance, attractive operating margins and strong exposure to copper and gold across Hudbay's diversified operating portfolio.
• Higher consolidated copper production of 30,152 tonnes and gold production of 69,513 ounces in the third quarter of 2026, representing a 7% and 36% increase, respectively, compared to the second quarter of 2026.
• Continued to demonstrate industry-leading margins with consolidated cash costⁱ and sustaining cash costⁱ, net of by-product credits, of $(0.19) and $1.61 per pound of copper, respectively, in the third quarter of 2026.
• Reaffirmed full year 2026 consolidated production guidance including 110,000 to 138,000 tonnes of copper and 217,000 to 272,000 ounces of gold.
• Further improved full year 2026 consolidated cash costⁱ guidance range to $(0.55) to $(0.35) per pound of copper, an additional improvement from the previously updated guidance range of $(0.45) to $(0.25) per pound of copper, as year-to-date results are trending well below the low end of the cash cost range.
• Improved full year 2026 consolidated sustaining cash cost guidance range to $1.40 to $1.80 per pound of copper from the original guidance range of $1.70 to $2.10 per pound of copper as a result of strong exposure to gold by-product credits and continued strong operating cost control. Full year 2026 consolidated sustaining capital expenditures expected to be $35 million lower than guidance levels due to lower capitalized stripping in Peru and British Columbia and capital deferrals and efficiencies.
• Peru operations demonstrated steady operating performance with production of 20,572 tonnes of copper and 5,267 ounces of gold in the third quarter of 2026. Peru cash costⁱ, net of by-product credits, of $2.23 per pound exceeded the upper end of the 2026 annual guidance range of $1.70 to $2.10 per pound primarily due to lower by-product credits, partially offset by better treatment and refining charges.
  • Achieved record Constancia mill throughput of approximately 91,000 tonnes per day in the third quarter, on track to achieve 34 million tonnes per annum in 2027.
• Manitoba operations demonstrated strong operating performance and executed on the commitment to deliver a stronger second half of 2026 with production of 57,261 ounces of gold, 3,012 tonnes of copper, 3,691 tonnes of zinc and 268,346 ounces of silver in the third quarter of 2026. Manitoba cash costⁱ of $403 per ounce of gold outperformed the low end of the 2026 annual guidance range of $500 to $800 per ounce as a result of higher by-product prices.
  • Continued to exceed Snow Lake mill performance expectations with record New Britannia mill throughput of 2,250 tonnes per day and record Stall gold recoveries of 73.6% in the third quarter.
• British Columbia operations showed improving operating performance with production of 6,568 tonnes of copper, 6,985 ounces of gold and 52,010 ounces of silver in the third quarter of 2026, in line with quarterly cadence expectations. British Columbia cash costⁱ of $3.09 per pound of copper was higher than the annual cost guidance range of $1.50 to $2.50 per pound primarily due to elevated fuel prices, higher fuel consumption from increased material moved and timing of equipment maintenance. While British Columbia cash cost is expected to improve in the fourth quarter with higher expected production volumes, full year cash cost is expected to track towards the high end of the annual guidance range.
  • Achieved Copper Mountain mill throughput of approximately 43,500 tonnes per day in September, reflecting successive monthly increases after the completion of mill maintenance at the primary SAG mill in July, and on track to achieve the targeted 50,000 tonnes per day by the end of the year. The third quarter represented the first quarter of positive free cash flowⁱ at Copper Mountain since its acquisition by Hudbay, demonstrating the benefits from continued operating efficiencies, recent mill improvement initiatives and ongoing execution of the accelerated stripping program.
• Third quarter earnings per share attributable to owners was $0.34, reflecting strong gross profit margins as a result of the continued focus on cost control and higher metal prices more than offsetting higher input costs. After adjusting for various non-cash items on a pre-tax basis, third quarter adjusted earningsⁱ per share attributable to owners was $0.34.
• Cash and cash equivalents were $788.7 million and total liquidityⁱⁱ was $964.3 million at the end of the third quarter of 2026, before giving effect to a $250 million increase in size to Hudbay’s credit facilities in November 2026. Cash and cash equivalents exclude $50.1 million in U.S. municipal bond proceeds that are classified as restricted cash and reflect $45.0 million in net purchases of investments and $22.0 million of debt repayments during the third quarter of 2026.

Record Trailing Twelve-Month EBITDA and Free Cash Flow Generation; Strong Balance Sheet and Significant Financial Flexibility

• Hudbay's unique copper and gold diversification across its operations, together with a focus on cost control across the business, continues to realize strong margins and generate significant free cash flow.
• Operating cash flow before changes in non-cash working capital was $313.9 million during the third quarter of 2026, reflecting an increase of $103.8 million compared to the second quarter as a result of record quarterly revenue and maintaining strong operating margins.
• Delivered free cash flowⁱ generation of $201.9 million during the third quarter of 2026, reflecting an increase of approximately $100 million compared to the second quarter through higher production and continued strong operating margins. Generated more than $400 million of free cash flow year-to-date in 2026 despite investing over $325 million of sustaining capital in the business over this period. This has resulted in record trailing twelve-month free cash flow generation of $631.0 million.
• Achieved quarterly adjusted EBITDAⁱ of $413.4 million in the third quarter of 2026, resulting in record trailing twelve-month adjusted EBITDAⁱ of $1,542.4 million.
• Recorded net debtⁱ of negative $0.1 million as at September 30, 2026, positioning the Company well to reinvest in high-return growth capital projects across the business, including the recently announced final investment decision (“FID”) to proceed with the development and construction of Copper World.
• Net debt to adjusted EBITDA ratioⁱ was 0.0x in the third quarter of 2026, significantly improved from 0.4x in the fourth quarter of 2025 as a result of the initial proceeds received from Mitsubishi Corporation (“Mitsubishi”) on closing of the Copper World joint venture transaction in January 2026, along with strong cash flows from operations.
• Consistent with Hudbay’s prudent balance sheet management and balanced capital allocation framework, Hudbay repaid $22.0 million of its outstanding $272 million draw on its revolving credit facilities in the third quarter of 2026.
• As announced with the Copper World FID in October, Hudbay proactively amended and extended its existing revolving credit facilities. Total capacity under the facilities was upsized from $450 million to $700 million and the maturity date of the facilities was extended by two years to November 2030. The amended credit agreements include an improved pricing grid and greater financial flexibility that reflects Hudbay’s robust cash flow, strong balance sheet position, and its recently upgraded credit rating. After adjusting for the $250 million increase in size of the credit facilities, Hudbay’s proforma liquidity as of September 30, 2026 is approximately $1.2 billion.

Advancing Brownfield and Greenfield Investments to Drive Strong Returns and Significant Production Growth

• Formally approved, along with Mitsubishi, the FID to proceed with the construction and development of Copper World as the next major copper mine in the U.S. with first production targeted for the second half of 2029. The FID is supported by robust economic returns with low capital intensity outlined in the Copper World definitive feasibility study and related pre-feasibility studies (collectively, the “DFS”) which delivers annual copper production of 102,000 tonnes over the first 10 years, an 11% increase when compared to 92,000 tonnes in Hudbay’s 2023 pre-feasibility study for Copper World (“2023 PFS”).
  • The base case for Copper World contemplates a 15-year mine life utilizing mineral reserves and requires only state and local permits (“Base Case”) and expands the concentrator in year five to enable a 43% increase in average annual copper production to 120,000 tonnes in years six to 10 compared to 84,000 tonnes over the first five years. The Base Case generates an after-tax net present value (8%) of $1.2 billion and internal rate of return of 17% at a long-term copper price of $5.00 per pound, which increases to $2.3 billion and 22%, respectively, at a copper price of $6.00 per pound.
  • The extension case for Copper World contemplates a 37-year mine life utilizing only measured and indicated mineral resources and expands mining activities onto federal lands in year 10, subject to obtaining federal permits (“Extension Case”), maintaining annual copper production of 117,000 tonnes from years 11 to 20. The Extension Case generates an after-tax net present value (8%) of $2.5 billion and internal rate of return of 19% at a long-term copper price of $5.00 per pound, increasing to $4.0 billion and 24%, respectively, at a copper price of $6.00 per pound.
  • As a result of Hudbay’s capital allocation strategy and prudent Copper World funding plan, the levered internal rate of return to Hudbay increases to 32% at $5.00 per pound of copper long-term in the Base Case and to 44% at $6.00 per pound of copper in the Extension Case.
• Enhanced the gold production profile at Snow Lake and extended reserve mine life to 18 years with updated life of mine plan released in September. Total life-of-mine gold production increased by 60% and reserve mine life extended by an additional two years to 2043, which together with the four-year extension in March 2026 represents a total of six years added to the reserve mine life.
  • Updated five-year averageⁱⁱⁱ annual gold production of 185,000 ounces reflects continued strong mill throughput rates at New Britannia and higher gold recoveries at Stall, representing a 37% increase in total gold production from an additional 250,000 ounces produced over the same five-year period in the Snow Lake 2021 technical report.
  • Snow Lake updated mineral reserve estimates increased contained gold to 2.0 million ounces, and the updated mine plan represents a conservative view based on Hudbay’s historical high resource-to-reserve conversion rate of 90%^iv and ongoing exploration activities. There remains 1.5 million ounces of gold contained in inferred mineral resource estimates.
• Implementing mill enhancements at Constancia to drive further increases in mill throughput and copper recoveries. The completion of the installation of a third rougher line late in the third quarter is expected to drive higher copper recoveries starting in the fourth quarter. The installation of two pebble crushers is nearing completion with commissioning expected in November, resulting in increased processing capacity at the Constancia mill.
• Advancing the development of infrastructure at the New Ingerbelle extension project in British Columbia and de-risking the path to first production in late 2028. New Ingerbelle is expected to enhance the copper and gold production profile and secure a longer mine life at Copper Mountain.
• Advancing the recently acquired Cactus project in Arizona by initiating pre-feasibility study (“PFS”) activities, including multiple trade-off studies, with completion expected in the second half of 2027.
• Continuing to derisk the long-term Mason project in Nevada through PFS and other site activities. The Mason PFS is expected to be completed in the second half of 2027.
  

Positive Exploration Results Across the Business

• Recent exploration drilling in Peru intersected a potential new high-grade feeder system at Constancia in multiple drill holes, with highlights including 245 metres of 0.43% copper and 0.03% molybdenum, indicating high-grade expansion potential beneath and adjacent to the existing reserve and resource envelope. Follow up drilling is underway.
• Continuing to execute an extensive exploration program in Snow Lake from recently developed underground exploration drifts at Lalor and 1901 to enable infill drilling and testing of mineralized extensions, while also testing identified high-priority targets at the former producing New Britannia gold mine currently on care and maintenance (the “Britannia Gold Project”). Regional geophysics, mapping, structural modeling and data compilations underway to support target definition for new anchor deposits.
• Completing a targeted drilling program at New Ingerbelle focused on upgrading existing inferred resources to reserves to further optimize and extend the mine life at Copper Mountain. Results are expected to be incorporated in Hudbay’s annual reserve and resource update in March 2027.
  

Summary of Third Quarter Results

Hudbay's diversified asset portfolio delivered consolidated copper production of 30,152 tonnes and consolidated gold production of 69,513 ounces in the third quarter of 2026, positioning the Company well to meet full-year 2026 consolidated production guidance. Consolidated copper production was higher than the second quarter of 2026 as a result of record high mill throughput in Peru and higher grades offsetting lower mill throughput in British Columbia. Consolidated gold production was higher than in the second quarter of 2026 primarily due to increased throughput and grades in Manitoba. Consolidated silver production of 897,587 ounces was higher than the second quarter of 2026 primarily driven by increased mill throughput and higher grades, while zinc production of 3,691 tonnes in the third quarter of 2026 decreased compared to the second quarter of 2026, primarily reflecting lower zinc grades at the Manitoba operations.

Cash generated from operating activities was $214.9 million during the third quarter of 2026, reflecting a decrease of $82.1 million compared to the second quarter of 2026, primarily driven by unfavourable changes in non-cash working capital. Operating cash flow before changes in non-cash working capital was $313.9 million during the third quarter of 2026, an increase of $103.8 million compared to the second quarter of 2026, primarily reflecting higher realized copper prices and increased sales volumes.

Adjusted EBITDAⁱ was $413.4 million in the third quarter of 2026, a 29% increase compared to $321.2 million in the second quarter of 2026, primarily due to higher realized copper prices and higher copper, gold and silver sales volumes.

Net earnings attributable to owners was $149.5 million, or $0.34 per share, in the third quarter of 2026 compared to $137.4 million, or $0.34 per share, in the second quarter of 2026. The strength in aggregate earnings resulted from the aforementioned high revenue due to higher sales volumes of all metals, and cost control resilience in the face of higher diesel prices.

Adjusted net earnings attributable to ownersⁱ and adjusted net earnings per share attributable to ownersⁱ in the third quarter of 2026 were $149.5 million and $0.34 per share, respectively, after adjusting for various non-cash items on a pre-tax basis including $13.4 million in evaluation expenses, a $5.4 million mark-to-market revaluation net loss on various financial instruments, share-based compensation and offsetting mark-to-market gains on investments, a non-cash $11.8 million gain in re-evaluation adjustment on environmental provisions, among other items. This compares to adjusted net earnings attributable to ownersⁱ and net earnings per share attributable to ownersⁱ of $113.5 million and $0.28 per share, respectively, in the second quarter of 2026. The increase is a result of higher realized metal prices for copper and zinc and the aforementioned higher sales volumes.

Consolidated cash costⁱ, net of by-product credits, in the third quarter of 2026 was $(0.19) per pound of copper, compared to $(0.40) per pound in the second quarter of 2026. The increase from the second quarter of 2026 was in line with the expected cost cadence and is the result of lower by-product credits and slightly higher mine operating costs.

Consolidated sustaining cash costⁱ, net of by-product credits, in the third quarter of 2026 was $1.61 per pound of copper, compared to $1.39 per pound in the second quarter of 2026. This increase was primarily due to the same factors impacting consolidated cash cost noted above. Consolidated all-in sustaining cash costⁱ, net of by-product credits, in the third quarter of 2026 was $2.25 per pound of copper, higher than the second quarter of 2026 due to the same reasons noted above.

As at September 30, 2026, total liquidityⁱⁱ was $964.3 million, including $788.7 million in cash and cash equivalents, which excludes $50.1 million in U.S. municipal bond proceeds that are classified as restricted cash, and undrawn availability of $175.6 million under Hudbay's revolving credit facilities (prior to giving effect to the $250 million increase in size to the credit facilities in November 2026). Cash and cash equivalents reflect $45.0 million in net purchases of investments and $22.0 million in debt repayments during the third quarter of 2026. Net debtⁱ at the end of the third quarter was negative $0.1 million. Hudbay expects that its current liquidity, together with cash flows from operations, will be sufficient to meet the Company's liquidity needs for the next 12 months. With the successful execution of its disciplined capital allocation strategy, attracting Mitsubishi as a long-term strategic joint venture partner and a prudent project funding plan, Hudbay’s Copper World capital contributions are expected to be approximately $500 million, representing less than 25% of the initial growth capital, with capital contributions not expected to be required until 2028.

The Peru operations continued to demonstrate steady operating performance during the third quarter of 2026, with production and costs well-positioned to achieve the annual guidance ranges. Constancia achieved record quarterly total material moved at the mine and record quarterly ore milled during the third quarter of 2026, reflecting the benefits from efforts to improve productivity and further optimize the operations.

The Company completed the installation of a third rougher line in September, which resulted in immediate improvements in copper recoveries. Hudbay continues to advance the installation of pebble crushers at Constancia to increase mill throughput rates starting in the fourth quarter of 2026, which will allow the mine to continue to deliver steady annual copper production despite lower grades following the depletion of Pampacancha at the end of 2025.

During the third quarter of 2026, the Peru operations produced 20,572 tonnes of copper, 5,267 ounces of gold, 577,231 ounces of silver and 301 tonnes of molybdenum. Production of copper, silver and molybdenum was slightly higher compared to the second quarter of 2026, reflecting higher mill throughput as a result of efficiency improvements and the impacts of the planned semi-annual plant maintenance shutdown during the second quarter of 2026. Production of gold was comparable to the second quarter of 2026. Hudbay is on track to achieve its 2026 production guidance for all metals in Peru with gold production expected to exceed the top end of the guidance range.

Total material moved during the third quarter of 2026 was 25.0 million tonnes, reflecting operational efficiencies from mining exclusively in one pit, including shorter hauling distances and improved productivity resulting from haul route optimizations. These optimizations resulted in achieving a new monthly record for total volume of material moved in July 2026. Total ore mined during the quarter increased by 16% to 12.7 million tonnes compared to the second quarter of 2026, supported by active mining across three exposed ore phases and positive reconciliation yielding higher tonnage than predicted by the geological model.

Constancia achieved record mill throughput levels of approximately 91,300 tonnes per day in the third quarter of 2026, representing a 7% increase compared to the second quarter of 2026, primarily due to higher plant availability and lower ore hardness, as well as the benefits of increased mill processing capacity supported by the recently approved permit amendment. Milled copper grades and gold grades remained consistent with the second quarter of 2026. Metal recoveries remained in line with expectations.

Combined mine, mill and G&A unit operating costⁱ in the third quarter of 2026 was $13.60 per tonne, representing a 3% decrease compared to the second quarter of 2026, primarily due to higher ore tonnage milled and reduced mill maintenance costs following the completion of the planned semi-annual plant maintenance shutdown in the second quarter. This efficiency gain was partially offset by higher social spending during the quarter.

Cash costⁱ, net of by-product credits, in the third quarter of 2026 was $2.23 per pound of copper, an increase of 34% compared to the second quarter of 2026, primarily due to lower silver and gold by-product credits and higher profit sharing, combined with the continued higher fuel prices with higher fuel consumption from increased material moved. This was partially offset by lower plant maintenance costs following the completion of the semi-annual mill shutdown in the second quarter of 2026.

Year-to-date cash cost continues to outperform the low-end of the 2026 guidance range as a result of strong operating cost performance and higher by-product prices, despite external cost pressures. Hudbay is well positioned to achieve the full year 2026 cash cost guidance range in Peru.

Sustaining cash costⁱ, net of by-product credits, in the third quarter of 2026 was $3.23 per pound of copper, an increase of 19% compared to the second quarter of 2026, primarily due to the same reasons affecting cash costs above, as well as higher hauling costs related to additional material sent to the tailings management facility.

As part of the Company’s continuous improvement efforts, Hudbay obtained updated permits in 2026 to enable additional capacity to further optimize Constancia’s operations and deliver strong copper production. In June 2026, the Company received approval from the National Environmental Certification Service for Sustainable Investments in Perú (SENACE) to amend its environmental permit and further increase annual mill processing capacity at Constancia. This represented the fifth environmental permit amendment at Constancia. The amended permit increases the processing capacity of the Constancia mill to 34 million tonnes of ore per annum from the previously permitted 31 million tonnes per annum. The corresponding operating permit for this expansion is expected to follow in due course. In March 2026, Hudbay received the previous operating permit to increase mill throughput capacity to 31 million tonnes from 29.9 million tonnes per annum. The Peru Ministry of Energy and Mines’ regulatory framework provides operational flexibility to handle daily increases of up to 10% above permitted levels.

The Manitoba operations delivered strong operating performance in the third quarter of 2026, driven by the achievement of key operational performance targets and the benefits from strategic initiatives implemented earlier in the year, positioning the business to achieve full-year guidance metrics while advancing key growth and infrastructure projects.

Performance at the Lalor mine significantly improved during the third quarter, with improved equipment utilization driving efficiencies in underground development, and higher gold and copper head grades contributing to increased production compared to the second quarter of 2026.

To address prior labour availability constraints and accelerate development at the 1901 deposit, Hudbay embedded an experienced mining contractor at 1901, allowing internal skilled labour to be redeployed toward critical development areas at Lalor. In tandem, Hudbay expanded its internal capacity by onboarding over 150 new employees thus far in 2026, who are undergoing upskilling to support long-term self-sufficiency. Underground improvement efforts also advanced during the third quarter, including operational testing of a roadheader continuous mining unit at Lalor to understand lateral development applications.

The Manitoba operations produced 57,261 ounces of gold, 3,012 tonnes of copper, 3,691 tonnes of zinc and 268,346 ounces of silver in the third quarter of 2026. Production of gold, copper and silver increased compared to the second quarter of 2026 as a result of higher mill throughput and improved gold feed grades, while zinc production decreased due to lower zinc feed grades. Hudbay is on track to achieve its 2026 production guidance for all metals in Manitoba.

The Lalor mine hoisted an average of approximately 4,200 tonnes of ore per day during the third quarter of 2026, strategically prioritizing gold feed. Development activity at the 1901 deposit focused on exploration and infill drilling, orebody access, and critical infrastructure, with late 2027 remaining the targeted timeline for full production. Total ore mined in Manitoba in the third quarter of 2026 increased compared to the second quarter of 2026, driven by improved equipment utilization and haulage efficiencies. The gold grades increased by 16% compared to the second quarter of 2026 as production prioritized gold-focused mining areas.

The New Britannia mill achieved a new quarterly mill throughput record, averaging approximately 2,250 tonnes per day in the third quarter of 2026, aligning with gold ore output from Lalor and achieving new record gold recoveries of approximately 92% during the quarter.

The Stall mill demonstrated higher quarterly throughput compared to the third quarter of 2025 and the second quarter of 2026, matching Lalor base metal production, while achieving new record gold recoveries of 74% as a result of recovery focused initiatives.

Combined mine, mill and G&A unit operating costsⁱ were C$282 per tonne in the third quarter of 2026. Combined unit costs improved from the second quarter of 2026 as higher ore throughput offset elevated variable site expenses, including operational testing of the continuous miner unit at Lalor.

Cash costⁱ, net of by-product credits, was $403 per ounce of gold in the third quarter of 2026. This represents a decrease of 48% compared to the second quarter of 2026, primarily due to higher gold production and higher by-product credits driven by higher metal prices and volumes, which were partially offset by higher mining and G&A costs. Hudbay is well positioned to achieve its 2026 cash cost guidance range in Manitoba.

Sustaining cash costⁱ, net of by-product credits, was $898 per ounce of gold in the third quarter of 2026, lower than the second quarter of 2026, primarily reflecting the same factors affecting cash costs, partially offset by higher sustaining capital. As reflected in the Company's 2026 annual guidance, sustaining capital expenditures are expected to be higher than 2025, in part due to one-time investments to raise the dam at the Anderson Tailings Impoundment Area and the New Britannia mill cyanide recycling project.

Hudbay initiated early works on the Stall Hot Tails Leaching project to unlock additional gold recovery from material processed at the Stall mill through leaching at New Britannia. Hudbay has also initiated early evaluation work on processing legacy tailings and mineralized piles to utilize excess mill capacity.

Hudbay continued to advance its multi-year optimization plan at Copper Mountain, achieving significant milestones in mining productivity, operational performance, and project execution in the third quarter of 2026. In parallel, Hudbay has continued to focus on improving safety and environmental management and received ISO 14001 and 45001 certifications at Copper Mountain during the third quarter of 2026.

The third quarter represented the first quarter of positive free cash flowⁱ at Copper Mountain since its acquisition by Hudbay, demonstrating the benefits from continued operating efficiencies, recent mill improvement initiatives and ongoing execution of the accelerated stripping program.

The British Columbia operations produced 6,568 tonnes of copper, 6,985 ounces of gold and 52,010 ounces of silver in the third quarter of 2026. Compared to the second quarter of 2026, copper and gold production increased as higher head grades and improved recoveries offset the impact of maintenance downtime on the primary SAG mill. Silver production decreased due to localized head grade variations. Hudbay is on track to achieve its 2026 full year production guidance for all metals in British Columbia.

Total material movement at Copper Mountain was approximately 26.9 million tonnes (approximately 292,300 tonnes per day) in the third quarter of 2026. Compared to the second quarter of 2026, total material movement decreased by 11% due to fleet availability constraints and reduced productivity in the active mining areas. Waste movement associated with the New Ingerbelle east haul road development totaled 5.6 million tonnes during the quarter.

Total ore mined at Copper Mountain in the third quarter of 2026 was 5.1 million tonnes, an increase of 56% compared to the second quarter of 2026. The increase was driven by favourable ore release timing from the north pit.

Copper Mountain achieved mill throughput of approximately 43,500 tonnes per day in September, reflecting successive monthly mill throughput increases after the completion of mill maintenance at the primary SAG mill in July, and Hudbay is on track to achieve the targeted 50,000 tonnes per day by the end of the year. The mill processed 3.1 million tonnes of ore during the third quarter of 2026, 15% lower than the second quarter of 2026, reflecting 33 days of planned maintenance downtime for the primary SAG mill feed end head replacement. Higher hourly operating throughput following the restart partially offset the planned outage.

Milled copper head grades averaged 0.27% in the third quarter of 2026, representing an increase of 17% compared to the second quarter of 2026, due to higher grade ore released from active mining faces. Copper recoveries slightly increased to approximately 80% in the third quarter, representing an improvement compared to the second quarter of 2026. Gold recoveries were lower than the second quarter of 2026, while circuit optimization efforts continue to focus on managing flotation response at coarser grind sizes.

Combined mine, mill and G&A unit operating costsⁱ in the third quarter of 2026 were C$34.20 per tonne milled, higher than the second quarter of 2026. This unit operating cost increase was driven by lower capitalized stripping, higher fuel and mobile equipment maintenance costs, and additional maintenance expenses associated with the planned primary SAG mill shutdown.

Cash costⁱ, net of by-product credits, in the third quarter of 2026 was $3.09 per pound of copper produced. Cash cost decreased by 4% compared to the second quarter of 2026, benefiting from higher copper production, lower treatment and refining charges, and strong gold and silver by-product credits, which offset higher site operating costs. Higher copper production is expected in the fourth quarter of 2026 resulting in full year cash costs expected to track toward the high end of the annual guidance range in British Columbia.

Sustaining cash costⁱ, net of by-product credits, was $6.30 per pound of copper in the third quarter of 2026, slightly higher than the second quarter of 2026 due to higher royalty costs, partially offset by lower cash costs and reduced sustaining capital expenditures.

Following the June groundbreaking, the New Ingerbelle project continued to advance infrastructure development in the third quarter of 2026, with construction of key infrastructure connecting the expansion on the west side of the Similkameen river to existing operations on the east side progressing on schedule. Key milestones achieved during the quarter included completion of the west access road and establishment of a temporary construction bridge to facilitate the installation of the permanent bridge. Hudbay also continued to advance construction of the east haul road, which was 38% complete at the end of the third quarter. The New Ingerbelle expansion is expected to support continuous operations beyond 2040 and provide access to higher grade ore at approximately one third of the strip ratio compared to recent historical mining areas.

Approved Copper World Project Construction; Advancing Next Major U.S. Copper Mine Towards First Production in 2029

Hudbay and Mitsubishi have formally approved the FID to proceed with the construction and development of Copper World as the next major copper mine in the U.S. with first production targeted for the second half of 2029. Hudbay filed the National Instrument 43-101 (“NI 43-101”) technical report in support of the DFS in October 2026, concurrently with the Copper World FID.

Copper World will be one of the largest open-pit copper mines in the United States. It is anticipated to increase Hudbay’s consolidated annual copper production to approximately 250,000 tonnes, doubling current production levels together with other brownfield growth projects underway. The DFS outlines annual copper production of 102,000 tonnes over the first 10 years, an 11% increase when compared to 92,000 tonnes in Hudbay’s 2023 PFS. Copper World is expected to deliver average annual EBITDAⁱ of $661 million over the first 10 years in the Base Case and $735 million over the next 10 years in the Extension Case at a copper price of $5.00 per pound. Using a copper price of $6.00 per pound, Copper World’s annual EBITDA over these periods increases to $859 million and $963 million in the Base Case and Extension Case, respectively, representing an 80% to 90% increase in Hudbay’s consolidated annual EBITDA as compared to 2025.

The Base Case presented in the DFS is used to support the mineral reserve estimates of 390 million tonnes with strong copper grades of 0.47% over a 15 year mine plan. Total mill feed tonnage in the Base Case is comparable to the 2023 PFS. The Base Case is limited to the exterior boundary of Copper World’s private landholdings requiring only state and local permits. All major permits have been obtained for construction and initial operations.

• Base Case after-tax net present value (8%) is $1.2 billion with an internal rate of return of 17% and an initial payback period of 5.4 years at a long-term copper price of $5.00 per pound. At a copper price of $6.00 per pound, the after-tax net present value (8%) increases to $2.3 billion and the internal rate of return increases to 22%.
• Base Case average annual copper production is 102,000 tonnes over the first 10 years at average cash costs^v and sustaining cash costs^v of $1.65 and $2.22 per pound of copper, respectively.
• Base Case further optimizes the 2023 PFS mine plan with an in-pit crushing and conveying system in year four and an expansion of the concentrator from 60,000 tons per day to 90,000 tons per day in year five.
• Concentrator expansion enables a 43% increase in average annual copper production to 120,000 tonnes in years six to 10 compared to 84,000 tonnes over the first five years.
• Base Case annual average EBITDA is $566 million over the mine life at a long-term copper price of $5.00 per pound, increasing to $742 million at a long-term copper price of $6.00 per pound.
  

The Extension Case reflects a phased development approach that minimizes initial waste rock movement while operations remain constrained to the existing exterior boundary over the first 10 years and then expand beyond Copper World’s private property and onto its unpatented lode and mill site claims starting in year 10 to achieve and sustain a higher total material movement capacity. The Extension Case contemplates a 37-year mine life utilizing only measured and indicated mineral resources totalling 1,048 million tonnes and requires federal permits by year 10 of operations.

• Extension Case after-tax net present value (8%) is $2.5 billion with an internal rate of return of 19% and an initial payback period of 5.4 years at a long-term copper price of $5.00 per pound. At a copper price of $6.00 per pound, the after-tax net present value (8%) increases to $4.0 billion and the internal rate of return increases to 24%.
• Extension Case average annual copper production over the first 10 years is similar to the Base Case with 101,000 tonnes and increases to 117,000 tonnes over the period from year 11 to 20. Average cash costs^v and sustaining cash costs^v over the 10-year period from year 11 to 20 are expected to be $1.76 and $2.20 per pound of copper, respectively.
• Extension Case average annual EBITDA is $522 million over the mine life and $735 million over the period from year 11 to 20 at a long-term copper price of $5.00 per pound.
  

Copper World is one of the lowest capital intensity copper projects, maintaining an attractive capital intensity of approximately $22,600 per annual copper tonne using average production in years five to twelve, including the expansion growth capital in years three and four. With initial growth capital of $2.07 billion^vi ($1.84 billion net of precious metals stream deposit), which includes approximately $200 million related to changes in project scope since the 2023 PFS, Hudbay has put in place prudent funding and a low leverage financing plan. The sources of capital include Mitsubishi’s $600 million initial joint venture equity investment and Wheaton Precious Metals Corp.’s $230 million deposit for the existing precious metals stream, followed by approximately $650 million in anticipated project-level debt financing, representing less than 30% leverage. This defers Hudbay’s first pro-rata equity capital contribution to 2028.

With the prudent funding structure, the levered internal rate of return to Hudbay increases to 32% at $5.00 per pound of copper long-term in the Base Case and to 44% at $6.00 per pound of copper in the Extension Case. Copper World’s FID enables Hudbay to deliver its growth initiatives and maximize long-term risk-adjusted returns, while maintaining strong financial discipline within Hudbay’s holistic capital allocation framework.

Hudbay’s 2026 growth capital spending guidance related to the Copper World joint venture includes approximately $135 million of expenditures before the FID. As previously disclosed with the sanctioning of Copper World, the Company now expects full year growth expenditures related to the Copper World joint venture to total $245 million in 2026, reflecting an increase of $110 million related to project construction and development costs in the fourth quarter of 2026, as previously disclosed with the FID announcement in October 2026.

Executing Staged U.S. Growth Investment Strategy to Unlock Copper Growth Pipeline

Hudbay continues to invest across its United States platform beyond Copper World through advancing PFS activities at both Cactus and Mason. These assets along with Copper World strengthen Hudbay’s position as a premier Americas-focused copper company with a pipeline of long‑life, low‑cost assets located in tier-one jurisdictions.

The Cactus project is a highly complementary copper growth asset in Arizona, with potential to generate significant operational efficiencies and regional synergies with Hudbay's staged development of Copper World and Cactus. After the completed acquisition of Arizona Sonoran Copper Company Inc. in the second quarter of 2026, Hudbay announced it expects to spend approximately $30 million at Cactus in the second half of the year to advance an updated PFS, perform site de-risking activities, conduct exploration activities and for other ongoing site costs. The updated Cactus PFS, including multiple trade-off studies, is expected to be completed in the second half of 2027.

The Mason project, in Nevada, is one of the largest undeveloped copper porphyry deposits in North America and is viewed as a long-term future development asset as part of Hudbay’s pipeline of high-quality copper growth opportunities. The Company continued to progress PFS activities at Mason during the quarter and expects to spend approximately $20 million in evaluation expenses at Mason in 2026, as announced previously. The Mason PFS is approximately 45% complete and is expected to be completed in the second half of 2027.

Enhanced Gold Production Profile at the Snow Lake Operations

Hudbay released an updated Snow Lake mine plan on September 28, 2026. The updated Snow Lake mine plan reflects a 37% increase in gold production over the next five yearsⁱⁱⁱ and a 60% increase in total gold production over the life-of-mine, based on current mineral reserves, compared to the prior 2021 Snow Lake technical report. The updated Snow Lake mine plan maintains average production of 185,000 ounces of gold over the next five yearsⁱⁱⁱ reflecting several optimization initiatives including higher mill throughput at New Britannia and higher gold recoveries at the Stall mill to better utilize the combined 6,300 tonnes per day of processing capacity.

The updated Snow Lake mine plan reflects a mining ramp up to approximately 2.0 million tonnes per year and maintains this profile over the next decade. This reflects Lalor operating at 4,000 to 4,500 tonnes per day, supplemented by contributions from the 1901 deposit and several additional satellites to supplement Lalor mill feed and increase total ore mined to approximately 5,000 tonnes per day.

Snow Lake’s proven and probable reserve mine life has been extended by an additional two years to 2043, which together with the four-year extension announced in March 2026 represents a total of six years added to the reserve mine life. Current mineral reserve estimates in Snow Lake as of September 1, 2026 total 27.0 million tonnes with approximately 2.0 million ounces of gold. This represents an increase in mineral reserves of 7.5 million tonnes, unlocking 124,000 ounces of additional gold. Hudbay filed a technical report pursuant to NI 43-101 in support of the updated mine plan for Snow Lake on November 6, 2026.

The increase in reserves and extension of mine life is due to resource conversion at Lalor and 1901, higher reserves at the WIM and 3 Zone satellite deposits and the first reserve estimates for the Talbot and Rail satellite deposits following the completion of infill and geotechnical drilling. Hudbay expects to continue to achieve high rates of resource to reserve conversion and further optimize the mine plan.

The Snow Lake mine plan has been optimized for higher mill throughput rates at New Britannia maximizing gold production and cash flows. The New Britannia mill currently operates at more than 2,000 tonnes per day, continuing to exceed nameplate design of 1,500 tonnes per day, and the updated mine plan reflects New Britannia ramping up to 2,300 tonnes per day starting in 2027. The updated mine plan also reflects an additional recovery improvement project at Stall that aims to recover additional gold and silver through expansion of cyanide leaching and carbon adsorption infrastructure at New Britannia to accommodate material from Stall (the “Stall Hot Tails Leaching” project). Commissioning of Stall Hot Tails Leaching project is expected in early 2028 and it is anticipated to increase overall gold and silver recoveries.

Manitoba Exploration Strategy to Further Optimize the Mine Plan and Discover a New Anchor Deposit

Hudbay continues to advance many brownfield expansion and exploration opportunities in Snow Lake to further optimize the mine plan to maintain current annual gold production levels beyond 2030, extend mine life beyond 2043 and explore for new anchor deposits to provide significant gold production growth beyond the 180,000-ounce annual target. This includes executing an extensive exploration program in Snow Lake and more broadly across its highly prospective land package extending over 400,000 hectares across the Flin Flon-Snow Lake greenstone belt.

1) Conversion of Large Inferred Resources to Further Increase Production and Extend Mine Life – Continued infill drilling of existing resource base at Lalor and known satellites will continue to support mine plan optimization.

• Potential to convert the 1.5 million ounces of gold in inferred resources to reserves through infill drilling.
• Hudbay has historically converted approximately 90% of inferred resources to reserves at the Lalor deposit over the past five years^iv.

2) Extension of the Current Anchor Deposit at Lalor – Maximize value from existing infrastructure through mine life extension at the highest margin deposits, while extending the window of opportunity to discover a new anchor deposit.

• Lalor and 1901 continue to show extensions of high-grade, stacked lenses, and remain open down plunge.
• Mine life extensions at the current anchor will further increase cash flows and defer growth capital associated with the development of satellite deposits.

3) Discovery of a New Anchor Deposit – Meaningfully add to current production levels and significantly extend mine life through the discovery of the next major anchor deposit in the region.

• The Britannia Gold Project provides the opportunity to re-develop an underexplored, past-producing deposit with the potential to become a new anchor in the Snow Lake camp.
• Regional exploration on the large and highly prospective land package, including exploration for both volcanogenic massive sulphide (VMS) and orogenic gold deposits.
  

In the third quarter of 2026, advancement of underground exploration drifts at both Lalor and 1901 established new drilling platforms that will enable additional infill drilling of inferred resources and testing for extensions along mineralized trends in the high-grade copper-gold zones. At the Britannia Gold Project, digitization and remodeling of decades of historical data has identified several high-priority target areas laterally and down-plunge from known mineralization. Drilling from surface is currently underway and progressing in parallel to the assessment of options to restore historical underground access from the New Britannia shaft infrastructure. Regional airborne geophysics, mapping, structural modeling and data compilations progressed in the third quarter in both the Flin Flon and Snow Lake areas to support target definition for new anchor deposits.

Constancia Drilling Campaign Intersects Potential High-Grade Copper-Molybdenum Feeder System

Hudbay’s ongoing 2026 drilling exploration program at the Constancia operations in southern Peru has demonstrated high-grade expansion potential beneath and adjacent to the existing reserve and resource envelope, within the Company’s existing area of operations, as shown in Figure 1.

Two deep diamond drill holes successfully intersected lateral and down-dip extensions of the skarn envelopes and mineralized breccia zones below and adjacent to the Constancia pit. Drill holes CO-26-003 and CO-26-005 intersected significant widths of mineralized breccia extending beyond the limits of the current resource at grades higher than current reserve grades. A re-assessment of the localized structural and geological controls on mineralization is underway to support target definition for follow up drilling. The initial results indicate meaningful width and grade, while showing potential for orebody extensions at depth.

Highlights of the breccia drill hole intercepts are as follows (please refer to Exhibit 1 for further information):

• Hole CO-26-003 intersected 245 metres at 0.43% copper and 0.03% molybdenum, including 124 metres at 0.55% copper and 0.05% molybdenum from 478 metres.
• Hole CO-26-005 intersected 302 metres at 0.36% copper and 0.02% molybdenum from 396 metres, including 64 metres at 0.50% copper and 0.04% molybdenum from 618 metres.

Hudbay intends to continue ongoing geological and geochemical vectoring investigations to confirm the geometry and structural controls of this interpreted feeder system, as well as continue the exploration drilling to determine the potential scale and economic potential of mineralization both down-plunge and at depth. This high-grade system has the potential to enhance Constancia’s long-term production profile.

New Ingerbelle Infill and Expansion Drilling Nearing Completion

Hudbay is nearing completion of a 66,000-metre drill program aimed at converting inferred resources to measured and indicated categories at the New Ingerbelle deposit as well as testing possible extensions beyond the limits of the current mineral resource, the results of which are expected to be reflected in Hudbay’s annual mineral reserves and resources update in March 2027. Additional geotechnical drilling and geometallurgical sampling are underway to support mine plan optimization and metallurgical recovery modeling.

Proactive Two-Year Extension and Upsize of Senior Secured Revolving Credit Facilities

In November 2026, Hudbay completed the amendments to its senior secured revolving credit facilities to improve balance sheet resilience with a proactive two-year extension and upsize of the facilities. Under the amended credit agreements, the size of the credit facilities has been increased from the existing $450 million to $700 million, and the term has been extended to November 2030, providing additional financial flexibility to manage the maturity of Hudbay’s 2029 senior unsecured notes and develop the Copper World project. The amended credit agreement includes an improved pricing grid and greater financial flexibility that reflects Hudbay’s enhanced financial position and features an opportunity to increase the facilities by an additional $150 million at Hudbay’s discretion during the four-year tenor. After adjusting for the $250 million increase in size of the credit facilities, Hudbay’s proforma liquidity as of September 30, 2026 is approximately $1.2 billion.

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, net debt to adjusted EBITDA, free cash flow, 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 provide alternate measures 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. Free cash flow is shown as it provides investors and management additional information in assessing the Company's ability to generate cash flow from current operations after investing in capital to sustain the operations. 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.

The following tables provide detailed reconciliations to the most comparable IFRS measures.

¹ Per pound of copper produced.
² By-product credits are computed as revenue per financial statements, amortization of deferred revenue and pricing and volume adjustments.
³ Gold and silver by-product credits do not include variable consideration adjustments with respect to stream arrangements. Variable consideration adjustments are cumulative adjustments to gold and silver stream deferred revenue primarily associated with the net change in mineral reserves and resources or amendments to the mine plan that would change the total expected deliverable ounces under the precious metal streaming arrangement. For the three months ended September 30, 2026 the variable consideration adjustments amounted to $nil (three months ended September 30, 2025 - $nil and June 30, 2026 -$nil).
⁴ Depreciation is based on concentrate sold.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What were Hudbay's third-quarter 2026 earnings and production results?

Hudbay reported $149.5 million in net earnings attributable to owners, or $0.34 per share, on revenue of $765.9 million. Copper production reached 30,152 tonnes, up 7% from the second quarter, while gold production reached 69,513 ounces, up 36%.

What is Hudbay's updated 2026 cost guidance?

Hudbay lowered consolidated cash cost guidance, net of by-product credits, to negative $0.55 to negative $0.35 per pound of copper, from negative $0.45 to negative $0.25. Sustaining cash cost guidance fell to $1.40–$1.80 per pound from $1.70–$2.10.

What production expansion does Hudbay's Copper World base case include?

Copper World's base case includes a year-five concentrator expansion, increasing average annual copper production 43% to 120,000 tonnes in years six through 10 from 84,000 tonnes over the first five years. The base case uses mineral reserves over a 15-year mine life and requires only state and local permits.

What permits and economics apply to Hudbay's Copper World extension case?

The extension case requires federal permits to expand mining onto federal lands in year 10 and contemplates a 37-year mine life using measured and indicated resources. At $5.00-per-pound long-term copper, projected after-tax net present value at an 8% discount rate is $2.5 billion, with a 19% internal rate of return.
