TORONTO, May 01, 2026 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. (“Hudbay” or the “Company”) (TSX, NYSE: HBM) released its first quarter 2026 financial results today. All amounts are in U.S. dollars, unless otherwise noted.

“Hudbay delivered another quarter of record revenue, record adjusted EBITDA and record adjusted earnings, driven by steady operating performance, expanded margins from strong copper and gold exposure and a focus on cost control across the business,” said Peter Kukielski, President and Chief Executive Officer. “Our leading operating cost performance resulted in record low consolidated cash costs and contributed to continued strong free cash flow generation in the quarter. All our operations are on track to achieve 2026 production and cost guidance. Building on our commitment to prudent balance sheet management, we ended the quarter with over $1 billion in cash and cash equivalents. Our enhanced financial flexibility positions us well to advance the development of Copper World, invest in high-return opportunities at our operations and de-risk the Cactus project upon completion of the acquisition of Arizona Sonoran to deliver attractive growth and maximize long-term risk-adjusted returns for stakeholders.”

Achieved Record Adjusted EBITDA Driven by Stable Copper and Gold Production and Industry-Leading Margins; 2026 Production and Cost Guidance Reaffirmed

• Achieved record quarterly revenue of $757.3 million, record quarterly adjusted EBITDAⁱ of $421.9 million and record adjusted net earnings attributable to owners of $159.1 million in the first quarter, driven by steady operating performance, expanding margins from strong copper and gold exposure and a focus on cost control across the business.
• Consolidated copper and gold production of 27,929 tonnes and 61,700 ounces, respectively, in the first quarter was in line with quarterly cadence expectations.
• Industry-leading cost performance continues with record low consolidated cash costⁱ and sustaining cash costⁱ, net of by-product credits, of $(1.80) and $0.00, respectively, in the first quarter.
• 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. Reaffirmed 2026 cost guidance, including consolidated cash costⁱ guidance of $(0.30) to $(0.10) per pound of copper and sustaining cash costⁱ guidance of $1.70 to $2.10 per pound of copper.
• Peru operations produced 20,573 tonnes of copper and 8,770 ounces of gold in the first quarter of 2026, in line with quarterly cadence expectations after the depletion of Pampacancha at the end of 2025, offset by record mill throughput during the first quarter. Peru cash costⁱ, net of by-product credits, of $0.70 was better than expected as the Peru operations demonstrated strong cost control and benefitted from higher by-product prices.
• Manitoba operations produced 47,743 ounces of gold, 2,535 tonnes of copper, 4,565 tonnes of zinc and 213,208 ounces of silver in the first quarter of 2026, in line with quarterly cadence expectations. Manitoba cash costⁱ of $408 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.
• British Columbia operations produced 4,821 tonnes of copper, 5,187 ounces of gold and 43,042 ounces of silver in the first quarter of 2026, in line with quarterly cadence expectations. British Columbia cash costⁱ of $2.41 per pound of copper was within the 2026 annual cost guidance range of $1.50 to $2.50 per pound.
• First quarter net earnings attributable to owners and earnings per share attributable to owners were $190.4 million and $0.48, respectively, reflecting the strong gross profit margins as a result of higher metal prices. After adjusting for various non-cash items on a pre-tax basis, first quarter adjusted earningsⁱ per share attributable to owners was $0.40.
• Cash and cash equivalents were $1,003.8 million and total liquidityⁱⁱ was $1,429.0 million at the end of the first quarter of 2026, benefitting from the approximate $420 million initial cash contribution from Mitsubishi Corporation ("Mitsubishi") received on closing of the Copper World joint venture transaction in January 2026.
  
  

Continued Strong Financial Discipline and Prudent Balance Sheet Management

• Hudbay's unique copper and gold diversification across its operations provides exposure to higher copper and gold prices, which together with a focus on cost control across the business, continues to expand margins and generate attractive free cash flow.
• While the majority of Hudbay's revenue continues to be derived from copper production, revenue from gold production represents a meaningful portion of total revenues. Gold revenues were 39% of gross revenue in the first quarter of 2026.
• Delivered free cash flowⁱ generation of $102.3 million during the first quarter of 2026.
• Achieved record quarterly adjusted EBITDAⁱ of $421.9 million in the first quarter of 2026, resulting in record trailing twelve month adjusted EBITDAⁱ of $1,195.6 million.
• Net debtⁱ decreased by $434.1 million to $5.6 million as at March 31, 2026 compared to $439.7 million at December 31, 2025, benefitting from the closing of the Copper World joint venture transaction in January 2026.
• Net debt to adjusted EBITDA ratioⁱ was 0.0x in the first quarter of 2026, significantly improved from 0.4x in the fourth quarter of 2025 as a result of the initial proceeds received Mitsubishi on closing of the Copper World joint venture transaction.
• Consistent with Hudbay’s prudent balance sheet management and focus on cost of capital, following the quarter, Hudbay repaid its outstanding 2026 senior unsecured notes on maturity on April 1, 2026, using a combination of cash on hand and a $272 million draw on its low-cost revolving credit facilities, providing the Company with continued financial flexibility in advance of a Copper World sanctioning decision later this year.
• Hudbay’s enhanced Capital Allocation Framework is embedded into its annual financial planning cycle to provide a holistic approach to capital allocation decisions to maximize long-term risk-adjusted returns, including capital deployment into brownfield projects, greenfield projects, strategic investments and exploration, while considering debt repurchases, share buybacks and dividends.
  
  

Advancing Generational Growth Investments to Further Enhance Copper and Gold Exposure

• Released annual reserve and resource update with mine life extensions and improved three-year production outlook, including a 24% increase in consolidated average annual copper production over the next three years, a four year mine life extension in Snow Lake to 2041 and a two year mine life extension at Copper Mountain to 2045.
• Closed the accretive $600 million joint venture transaction with Mitsubishi in January 2026, securing a premier, long-term 30% strategic partner for the development of Copper World. The Copper World definitive feasibility study (“DFS”) is on track for completion in mid-2026 with a project sanctioning decision expected in 2026.
• Received key permit amendments for the New Ingerbelle expansion project at Copper Mountain, enhancing the copper and gold production profile and securing a longer mine life.
• Announced acquisition of Arizona Sonoran Copper Company Inc. ("ASCU") to bring together two highly complementary copper growth assets in Arizona and 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. When completed, the acquisition is expected to enhance Hudbay’s long-term copper production profile, expand its U.S. growth pipeline, and benefit from increasing demand for domestically produced critical minerals in the U.S. through the staged development of Copper World and Cactus.
• Continued to advance a large Snow Lake exploration program to further increase near-term production and mineral reserves, test regional satellite deposits for additional mill feed to utilize available capacity at Stall and explore the large land package for a new anchor deposit to meaningfully extend mine life.
• Increased drilling activities at the copper-gold-zinc Talbot deposit near Snow Lake with eight drill rigs deployed and several step-out drill holes indicating resource expansion potential.
• Advancing plans to initiate a pre-feasibility study for the Mason copper project in Nevada.
  
  

Summary of First Quarter Results

Hudbay's diversified asset portfolio delivered consolidated copper production of 27,929 tonnes and consolidated gold production of 61,700 ounces in the first quarter of 2026. Consolidated copper and gold production was lower than the fourth quarter of 2025 due to the depletion of high grade Pampacancha ore in late 2025, partially offset by higher mill throughput in all three operations during the first quarter compared to the fourth quarter of 2025. Consolidated silver production of 787,449 ounces was lower than the fourth quarter of 2025 for similar reasons. Zinc production of 4,565 tonnes in the first quarter of 2026 also declined compared to the previous quarter, primarily reflecting lower ore grades at the Manitoba operations.

Cash generated from operating activities was $211.3 million and remained relatively consistent with the fourth quarter of 2025 as a result of a favourable change in non-cash working capital. Operating cash flow before changes in non-cash working capital was $208.7 million during the first quarter of 2026, reflecting a decrease of $128.2 million from the fourth quarter of 2025. This decrease primarily relates to higher cash taxes paid in the first quarter of 2026 compared to the fourth quarter of 2025.

Adjusted EBITDAⁱ was $421.9 million in the first quarter of 2026, achieving a new quarterly record and representing an increase compared to $385.9 million in the fourth quarter of 2025, as higher realized metal prices resulted in strong gross profit margins during the quarter.

Net earnings attributable to owners was $190.4 million, or $0.48 per share, in the first quarter of 2026 compared to $128.0 million, or $0.32 per share, in the fourth quarter of 2025. The increase is a result of lower depreciation due to the full depletion of Pampacancha realized in the fourth quarter of 2025 as well as increased mark-to-market gains on investments, partially offset by higher tax expense.

Adjusted net earnings attributable to ownersⁱ and adjusted net earnings per share attributable to ownersⁱ in the first quarter of 2026 were $159.1 million and $0.40 per share, respectively, after adjusting for various non-cash items on a pre-tax basis including a $38.7 million mark-to-market revaluation net gain on various instruments such as investments and share-based compensation and a non-cash $10.7 million foreign exchange loss, among other items. This compares to adjusted net earnings attributable to ownersⁱ and net earnings per share attributable to ownersⁱ of $86.0 million and $0.22 per share, respectively, in the fourth quarter of 2025. The increase is a result of higher realized metal prices and strong cost control across the operations resulting in higher gross profit margins.

Consolidated cash costⁱ, net of by-product credits, in the first quarter of 2026 was $(1.80) per pound of copper, compared to $(0.63) per pound in the fourth quarter of 2025, as Hudbay continued to demonstrate strong cost control across its operations and benefited from higher by-product metal prices. The decrease in cash costs from the fourth quarter of 2025 was a result of higher by-product credits reflecting the benefits of Hudbay's diversified asset portfolio with higher realized prices across all metals.

Consolidated sustaining cash costⁱ, net of by-product credits, in the first quarter of 2026 was $0.00 per pound of copper, compared to $0.94 per pound in the fourth quarter of 2025. This decrease was primarily due to the same factors impacting consolidated cash cost noted above, partially offset by planned higher cash sustaining capital expenditures compared to the first quarter of 2025.

Consolidated all-in sustaining cash costⁱ, net of by-product credits, in the first quarter of 2026 was $0.73 per pound of copper, lower than the fourth quarter of 2025 due to the same reasons noted above, partially offset by higher corporate general and administrative ("G&A") costs from the revaluation of Hudbay's share-based compensation due to a higher share price.

As at March 31, 2026, total liquidity was $1,429.0 million, including $1,003.8 million in cash and cash equivalents, and undrawn availability of $425.2 million under Hudbay's revolving credit facilities. Net debtⁱ at the end of the first quarter was $5.6 million, marking a $434.1 million improvement from fourth quarter of 2025 primarily as a result of the cash received upon closing of the Copper World joint venture transaction.

On April 1, 2026, Hudbay repaid the outstanding aggregate principal amount of $472.5 million of its 2026 senior unsecured notes (the "2026 Notes") on maturity using a combination of cash on hand and a $272.0 million draw on its low-cost revolving credit facilities. After giving effect to this repayment Hudbay's total liquidity decreased by $472.5 million to $956.5 million. The repayment of the 2026 Notes using available liquidity is consistent with Hudbay’s prudent balance sheet management and focus on cost of capital and provides the Company with continued financial flexibility in advance of a Copper World sanctioning decision later this year. 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.

The Peru operations continued to demonstrate steady operating performance with production and costs in line with expectations after the depletion of Pampacancha at the end of 2025. The Company continues to advance the installation of pebble crushers at Constancia to increase mill throughput rates starting in the second half of 2026, which will allow the mine to deliver steady annual copper production, despite lower grades following the depletion of Pampacancha. Hudbay’s efforts to increase mill throughput align with the Peru Ministry of Energy and Mines’ regulatory change to allow mining companies to operate up to 10% above permitted levels. On March 6, 2026, Hudbay received permit approval to increase annual mill throughput capacity to 31.1 million tonnes from 29.9 million tonnes, providing the new base for the 10% permitted allowance. As part of the Company’s continuous improvement efforts, plans for additional mill throughput increases are underway.

In the first quarter of 2026, the Peru operations produced 20,573 tonnes of copper, 8,770 ounces of gold, 531,199 ounces of silver and 380 tonnes of molybdenum. Production of copper and gold were lower than the fourth quarter of 2025 due to the depletion of Pampacancha at the end of 2025. Hudbay is on track to achieve its 2026 production guidance for all metals in Peru.

Total ore mined in Peru in the first quarter of 2026 was 10% higher than the fourth quarter of 2025, a sizable increase due to enhanced fleet efficiency and improved productivity from mining only in the Constancia pit as opposed to two pits previously. Mining activities in the Pampacancha pit were completed during the fourth quarter of 2025 and the remaining stockpiled Pampacancha ore was fully processed during January 2026.

Mill throughput levels averaged approximately 90,700 tonnes per day in the first quarter of 2026, achieving a new quarterly record. Total mill throughput increased to 8.2 million tonnes during the first quarter of 2026, higher than the fourth quarter of 2025 due to higher mechanical availability as the prior quarter was impacted by the temporary operational interruption due to social unrest and by a scheduled semi-annual mill maintenance shutdown. Milled copper and gold grades decreased compared to the fourth quarter of 2025, primarily due to Pampacancha depletion in late 2025 which yielded better ore grades. Metal recoveries were in line with expectations and varied due to different proportions of ore feed from stockpiles and pits.

Combined mine, mill and G&A unit operating costⁱ in the first quarter of 2026 was $11.61 per tonne, 20% lower than the fourth quarter of 2025 due to a scheduled semi-annual plant shutdown in November 2025 and lower power costs related to a new power purchase agreement that came into effect on January 1, 2026.

Cash costⁱ, net of by-product credits, in the first quarter of 2026 was $0.70 per pound of copper, a 23% increase compared to the fourth quarter of 2025 due to lower gold by-product credits resulting from lower gold sales volumes offset in part by lower profit sharing, lower power costs as noted above, lower treatment and refining charges and lower freight costs. However, cash cost for the quarter outperformed the low-end of the 2026 guidance range as a result of strong operating cost performance and higher by-product prices, despite emerging 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 first quarter of 2026 was $1.43 per pound of copper, a decrease of 7% compared to the fourth quarter of 2025 due to lower sustaining capital related to lower tailings management facility construction costs during 2026 and mine maintenance timing, partially offset by higher cash costs noted above.

In April 2026, Constancia was recognized as the safest open pit operation in Peru during the National Mining Safety Contest for its performance in 2025. This award reflects the Company’s unwavering commitment to safety and validates Constancia’s compliance with the highest operational safety and regulatory standards.

The Manitoba operations demonstrated strong operational agility in mitigating lower equipment utilization and labour availability at the Lalor mine, while continuing to prioritize gold ore feed for the New Britannia mill. This strategy successfully maintained strong gold production in the first quarter, supported by higher mill recoveries compared to the fourth quarter of 2025. Additionally, the operations achieved improved underground equipment availability, made significant advancements across the Flin Flon, Snow Lake, and Talbot exploration programs, and completed a successful graduation of a third Mining Fundamentals Training cohort.

In the first quarter of 2026, the Manitoba operations produced 47,743 ounces of gold, 2,535 tonnes of copper, 4,565 tonnes of zinc and 213,208 ounces of silver. Production of gold was higher than in the fourth quarter of 2025 due to higher gold recoveries and higher mill throughput, while all other metals were lower primarily due to lower grades. Production in the second half of 2026 is expected to be higher than the first half of 2026 due to grade sequencing and higher ore output from Lalor. With solid operating results in the first quarter of 2026, Hudbay is on track to achieve its 2026 production guidance for all metals in Manitoba.

The Lalor mine hoisted an average of approximately 3,900 tonnes of ore per day in the first quarter of 2026, strategically prioritizing gold zones to secure optimal feed for the New Britannia mill. Total ore mined at Lalor in the first quarter of 2026 was lower compared to the fourth quarter of 2025 because of lower effective utilization of equipment due to reduced workforce availability. Reduced workforce availability was offset by successfully onboarding nearly 80 new employees as recruitment and upskilling of employees are underway to increase proficiency of front-line employees. In the first quarter of 2026, gold grades decreased by 14% compared to the fourth quarter of 2025, in line with mine plan expectations.

The 1901 deposit delivered approximately 11,000 tonnes of development ore in the quarter, while continuing to advance haulage and exploration drifts to further delineate the orebody and support ongoing infrastructure projects. Looking ahead, the Company will prioritize exploration, definition drilling, orebody access, and establishing critical infrastructure as it continues to progress 1901 toward full production in 2027.

The New Britannia mill averaged approximately 2,000 tonnes per day in the first quarter of 2026, which includes consistent gold ore feed from Lalor and continued improvement initiatives to unlock future throughput capacity. The mill achieved gold recoveries of 90%, reflecting ongoing optimization efforts.

The Stall mill achieved improved gold recoveries of 73% in the first quarter of 2026, reflecting process optimization and enhanced gold recovery initiatives. The Stall mill processed more ore in the first quarter of 2026 compared to the fourth quarter of 2025, consistent with Lalor base metal production.

Combined mine, mill and G&A unit operating costs in the first quarter of 2026 was C$254 per tonne, a slight increase compared to the fourth quarter of 2025 due to higher onsite operating costs, partially offset by higher tonnes processed.

Cash costⁱ, net of by-product credits, in the first quarter of 2026 was $408 per ounce of gold, representing a decrease compared to the fourth quarter of 2025 driven primarily by an increase in by-product credit contributions due to higher realized prices, while gold production remained relatively consistent with the prior quarter. First quarter cash costs outperformed the low end of the cash cost guidance range, positioning Hudbay well to achieve the 2026 cash cost guidance range in Manitoba.

Sustaining cash costⁱ, net of by-product credits, in the first quarter of 2026 was $833 per ounce of gold, lower than the fourth quarter of 2025 primarily due to the same factors affecting cash costs, partially offset by higher sustaining capital.

The Snow Lake operations launched sustaining capital environmental projects, including a cyanide recycling initiative at New Britannia mill and pre-work for dam raise construction at the Anderson Tailings Impoundment Area to increase the physical tailings capacity, with both projects expected to be completed in 2026. As reflected in the Company’s annual guidance, sustaining capital expenditures are expected to be higher than 2025 due to these two investment projects.

During the first quarter of 2026, Hudbay continued to execute its multi-year optimization plan at Copper Mountain, achieving significant milestones in both mining productivity and project permitting. The Company remains on track to deliver the benefits of its three-year accelerated stripping program, positioned to unlock higher-grade ore in late 2026.

The British Columbia operations produced 4,821 tonnes of copper, 5,187 ounces of gold, and 43,042 ounces of silver in the first quarter of 2026, which is aligned with guidance and the planned mining sequence. Production of copper and gold in the first quarter of 2026 was higher than the fourth quarter of 2025, as higher throughput offset lower grades, while lower silver grades and recovery were not offset by higher throughput. Hudbay remains on track to achieve its 2026 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 reached a record total material movement of approximately 25.4 million tonnes in the first quarter, driven by an optimized mining sequence in the main pit and increased contributions from the north pit. This ramp-up was supported by the successful commissioning of a new production loader in January 2026. To further bolster the equipment fleet and add to this momentum, an additional shovel has been recently commissioned.

Total ore mined at Copper Mountain in the first quarter of 2026 was 2.9 million tonnes, an increase 22% compared to the fourth quarter of 2025. Mining activities continue to focus on improving operating routines towards defining a positive step change in performance of the mine material movement and mill throughput. Improvements include the optimization of the mining sequence, with improved bench configurations that eliminated phase interference, along with enhanced mobile equipment maintenance protocols leading to more consistent utilization of the mine fleet.

The mill processed 3.1 million tonnes of ore during the first quarter of 2026, an increase of 36% compared to the fourth quarter of 2025. Milling throughput benefitted from the completion of the second SAG mill and the mill optimization initiatives implemented in late 2025 resulting in increased mill throughput in the first quarter of 2026. Milled copper grades during the first quarter of 2026 were 23% lower than the fourth quarter of 2025, driven by lower grades in ore mined. Copper and gold recoveries in the first quarter of 2026 saw a marginal increase to 79% and 65%, respectively, when compared to the fourth quarter of 2025, in line with the expected performance range.

Mill performance continues to demonstrate improvement following the optimization efforts initiated in 2025. The second SAG mill delivered increased throughput in the quarter, averaging approximately 10,000 tonnes per day in March. While the primary SAG mill continues to operate under a reduced load and is being rigorously monitored ahead of a feed-end head replacement scheduled for late June and into July. The mill remains on track to achieve its permitted capacity of 50,000 tonnes per day in the second half of 2026.

Combined mine, mill and G&A unit operating costsⁱ in the first quarter of 2026 were C$25.23 per tonne milled, which were lower than the fourth quarter of 2025 due to higher milled throughput, partially offset by higher milling and G&A costs.

Cash costⁱ and sustaining cash costⁱ, net of by-product credits, were $2.41 and $7.81, respectively, per pound of copper, in the first quarter of 2026. Cash costⁱ was lower than the fourth quarter of 2025 primarily as a result of higher gold by-product credits and resolving the unplanned maintenance and downtime issues on the primary SAG mill, as these issues constrained throughput and elevated costs in the fourth quarter of 2025. The resulting increase in mill availability in the first quarter of 2026 allowed for higher mill throughput and enhanced operational efficiencies. First quarter cash costs were within the 2026 guidance range, and despite emerging external cost pressures, Hudbay expects to achieve the full year 2026 cash cost guidance range in British Columbia.

The New Ingerbelle project reached a major milestone in the first quarter of 2026 with the receipt of the Mines Act and Environmental Management Act amended permits. The receipt of amended permits for the New Ingerbelle project supports continued copper production, increased gold production and future mine life extension potential from the New Ingerbelle satellite pit. The project is designed to access higher-grade mineralization while improving operational efficiency with a stripping ratio approximately three times lower than current mining areas. With these key approvals, Hudbay is advancing critical infrastructure required for the New Ingerbelle project to extend the mine life at Copper Mountain. Infrastructure projects include construction of an access road and a bridge across the Similkameen River and development of an east haul road to link New Ingerbelle with existing Copper Mountain operations, as well as advancement of essential water management and electrical systems, and waste rock facilities. A large drill program was initiated during the first quarter at New Ingerbelle to improve resource definition and expansion.

In February 2026, the Company further solidified its commitment to sustainable development and community relations by finalizing refreshed Participation Agreements with the Upper Similkameen Indian Band (“USIB”) and the Lower Similkameen Indian Band (“LSIB”). These agreements ensure that the benefits of the Copper Mountain and New Ingerbelle operations continue to be shared with First Nation partners.

On March 23, 2026, the LSIB submitted an application for judicial review of the regulatory decision to grant the New Ingerbelle permit amendment. Hudbay remains confident in the integrity and robustness of the regulatory process that led to the issuance of the permit amendment and Hudbay believes the court will uphold the decision. At the same time, Hudbay remains committed to working with the LSIB in a respectful and constructive manner to try to resolve the LSIB's concerns through the mechanisms that were agreed to by the parties in the participation agreement.

In April 2026, the B.C. government added the New Ingerbelle project to the province's list of priority resource projects. This list highlights the acceleration of major projects that strengthen economic growth, support resource development and create jobs and long-term value.

Continued Free Cash Flow Generation Driven by Expanding Operating Margins; Emerging External Cost Pressures Insulated by Diversified Copper and Gold Exposure

Hudbay has delivered several quarters of significant free cash flow generation as a result of steady operating performance, expanding margins from strong copper and gold exposure and a focus on cost control across the business. While the majority of Hudbay's revenue continues to be derived from copper production, revenue from gold production represents a meaningful portion of total revenues. Gold revenues were 39% of gross revenue in the first quarter of 2026.

Hudbay’s cost control efforts are focused on navigating emerging external cost pressures, such as higher fuel prices and short-term labour challenges. The Company is not experiencing any disruption to fuel availability and is mitigating the cost pressures through initiatives to further improve throughput and enhance operating efficiencies. Hudbay benefits from its diversified platform with significant by-product credits from gold production and the polymetallic nature of the Company’s ore deposits.

With the Company’s prudent balance sheet management and further reduction in net debt during the first quarter of 2026, Hudbay is well-positioned to advance its generational growth investments across the portfolio and allocate capital to the highest risk-adjusted return opportunities to deliver significant value for stakeholders.

Copper World DFS On-track for Completion in Mid-2026

In January 2026, Hudbay announced the closing of the joint venture transaction with Mitsubishi, securing a premier, long-term strategic partner for the development of Copper World. The $420 million of initial proceeds received at closing from Mitsubishi will be used to directly fund the remaining DFS costs and pre-sanctioning costs in addition to the initial project development costs for Copper World. Mitsubishi will contribute an additional $180 million within 18 months of closing to complete its 30% minority investment and will also fund its pro-rata 30% share of future equity capital contributions.

Feasibility activities for Copper World are well underway with the DFS progressing above 85% completion at the end of March. The DFS continues to be on-track for completion in mid-2026. Hudbay continues to execute detailed engineering work and other de-risking activities in preparation for a Copper World sanctioning decision expected later in 2026.

Announced Acquisition of Arizona Sonoran to Create the Third Largest Copper District in North America

On March 2, 2026, Hudbay entered into a definitive agreement (the “Arrangement Agreement”) pursuant to which Hudbay has agreed to acquire all of the issued and outstanding common shares of ASCU, not already owned by Hudbay, for consideration of 0.242 of a common share of Hudbay per common share of ASCU (the “Transaction”). Following completion of the Transaction, Hudbay will own a 100% interest in ASCU’s Cactus project.

The Transaction brings together two highly complementary copper growth assets in Arizona and strengthens Hudbay’s position as a premier Americas-focused copper company with a pipeline of long-life, low-cost assets located in tier-one jurisdictions. When completed, the Transaction is expected to enhance Hudbay’s long-term copper production profile, expand its U.S. growth pipeline, and benefit from increasing demand for domestically produced critical minerals in the U.S. Significant operational efficiencies and regional synergies are expected with Hudbay's staged development of Copper World and Cactus.

The Transaction is subject to ASCU shareholder approval at a special meeting scheduled to be held on May 11, 2026 and customary regulatory approvals. The Transaction is expected to close in the second quarter of 2026.

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, 2026.

In Peru, current mineral reserve estimates total 488 million tonnes at 0.24% copper containing approximately 1.2 million tonnes of copper. The expected mine life of Constancia is now until 2040 as mill throughput rates are expected to increase to more than 90,000 tonnes per day starting in the second half of 2026 with the installation of two pebble crushers and related permit amendments. Constancia's three-year production guidance reflects stable annual copper production averaging approximately 87,500ⁱⁱⁱ tonnes of copper over the next three years, as the depletion of Pampacancha in 2025 is offset by higher mill throughput and operating efficiencies. 2027 and 2028 copper production is expected to be 90,000ⁱⁱⁱ tonnes, a 9% increase from 2026 expected copper production of 82,500ⁱⁱⁱ tonnes, benefitting from a full year of increased mill throughput, operating efficiencies and mine plan optimization to smooth copper production over the three-year period. The benefits of the mine plan optimization initiatives extend beyond the 3-year outlook with 2029 copper production expected to continue near these levels.

In Snow Lake, current mineral reserve estimates total approximately 19.6 million tonnes with approximately 1.9 million ounces of gold and support a mine life to 2041, representing an extension of four years. 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. The ongoing exploration program in the region remains a core priority, focusing on near-mine extensions and regional satellite deposits to utilize available milling capacity. Manitoba’s three-year production guidance reflects continued strong gold production levels averaging 190,000ⁱⁱⁱ ounces per year. New Britannia mill throughput is expected to continue to exceed expectations and operate above 2,200 tonnes per day, far exceeding its original design capacity of 1,500 tonnes per day. The production guidance anticipates Lalor operating between 4,000 to 4,500 tonnes per day, supplemented by contributions from the 1901 deposit with a ramp up to 1,000 tonnes per day by 2028. In 2026, Hudbay expects to complete a feasibility study on the Stall mill tailings leaching project, which has the potential to further increase gold production starting in 2028. The benefits of this project have not been reflected in the production guidance.

In British Columbia, current mineral reserve estimates total 345 million tonnes at 0.26% copper and 0.12 grams per tonne gold, containing approximately 883 thousand tonnes of copper and 1.3 million ounces of gold. These mineral reserves support a mine life until 2045, representing an extension of two years, with additional upside potential for future resource conversion and mine life extension through 122 million tonnes of measured and indicated resources grading 0.21% copper and 0.10 grams per tonne gold and 347 million tonnes of inferred resources grading 0.24% copper and 0.12 grams per tonne gold, in each case exclusive of mineral reserves. British Columbia’s three-year copper production guidance reflects sequentially higher copper production averaging 48,000ⁱⁱⁱ tonnes per year, as a result of the completion of the conversion of the third ball mill to second SAG mill in late 2025, installation of the replacement feed-end head at the primary SAG mill in the third quarter of 2026, and higher grades from the completion of the accelerated stripping program in 2026. 2027 and 2028 copper production is expected to average 57,500ⁱⁱⁱ tonnes, almost double 2026 expected copper production of 30,000ⁱⁱⁱ tonnes, benefitting from a full year of mill throughput at the targeted 50,000 tonnes per day and the unlocking of higher grades from the accelerated stripping program. British Columbia’s annual gold production is expected to average approximately 35,000ⁱⁱⁱ ounces of gold over the next three years, reflecting sequentially higher gold production averaging 38,500ⁱⁱⁱ ounces over 2027 and 2028, a 43% increase from 2026, as a result of the expected contribution from New Ingerbelle starting in 2028.

Consolidated copper production is expected to average 147,000ⁱⁱⁱ tonnes per year over the next three years, an increase of 24% from 2025 levels. Consolidated copper production is expected to average 159,000ⁱⁱⁱ tonnes per year in 2027 and 2028, representing a 28% increase from expected 2026 production. The increase is due to higher expected copper production in British Columbia as a result of mill throughput ramping up to the targeted 50,000 tonnes per day in the second half of 2026, higher grades in British Columbia in 2027 from the completing of the accelerated stripping program, and higher expected mill throughput in Peru from the addition of two pebble crushers and operating efficiencies in the second half of 2026. Consolidated gold production is expected to average 243,000ⁱⁱⁱ ounces per year over the next three years, reflecting continued strong production in Manitoba and the expected contribution from New Ingerbelle in British Columbia starting in 2028.

Large Exploration Drill Program Continues in Snow Lake

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 to Further Increase Near-term Production and Extend Mine Life – Near-mine exploration at the Lalor mine and the adjacent 1901 deposit continued to support near-term production growth and mine life extension. The exploration program will continue during 2026 to potentially increase mineral reserves and resources and enable resource conversion. The Company completed development of the initial exploration drift at the 1901 deposit in 2025 and commenced delivery of zinc-rich development ore for processing at Stall. Activities at the 1901 deposit over the next two years will focus on exploration and definition drilling, orebody access and establishing the critical infrastructure required to support full production beginning in late 2027. Exploration activities will include step-out drilling to potentially extend the orebody, as well as infill drilling aimed at converting inferred mineral resources within the gold lenses to mineral reserves.
• Testing Regional Satellite Deposits to Utilize Available Processing Capacity and Increase Production – Hudbay increased its regional 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. The deposits acquired as part of the Rockcliff acquisition, 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, New Britannia, Rail, Pen II, Watts, 3 Zone and WIM deposits. The continued strong performance from the New Britannia mill has freed up processing capacity at the Stall mill, where there is approximately 1,500 tonnes per day of available capacity which could be utilized by regional satellite deposits to potentially increase production and extend the life of the Snow Lake operations beyond 2041.
• Exploring Large Land Package for New Anchor Deposit to Significantly Extend Mine Life – A majority of the land claims acquired as part of the Rockcliff acquisition in 2023 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 includes 600 kilometres of ground electromagnetic surveys and an extensive airborne geophysics survey in 2026.
  
  

Talbot Drilling Confirms Resource Expansion Potential

Talbot is a copper-zinc-gold rich volcanogenic massive sulfide (“VMS”) deposit located within trucking distance of existing processing infrastructure in Snow Lake. Successful drilling campaigns are expected to expand the resource base and support a pre-feasibility study (“PFS”) aimed at upgrading mineral resources to mineral reserves and extending the overall mine life of the Snow Lake operations. During the first quarter of 2026, the drilling program was expanded to a fleet of eight drill rigs to fast track the completion of the infill portion of the program. Six of the rigs will remain at site in the second quarter to focus on geotechnical drilling required for the PFS and testing additional targets to expand the footprint of the deposit at depth. These efforts will determine the future scope of a PFS including shaft versus ramp access and the best location for a future exploration drift. Hudbay intends to update Rockcliff’s prior mineral resource estimate for Talbot using Hudbay’s standard methods that have demonstrated high mineral resource to reserve conversion rates.

Dividend Declared

A quarterly dividend of C$0.01 per share was declared on April 30, 2026. The dividend will be paid out on June 26, 2026 to shareholders of record as of close of business on June 9, 2026.

In February 2026, Hudbay's Board of Directors approved the introduction of a new quarterly dividend of C$0.01 per share as the Company achieved certain financial milestones ahead of schedule and significantly improved its financial position. The new total annual dividend amount of C$0.04 per share represents an increase of 100% or C$0.02 per share over the previous total annual dividend, which was paid semi-annually, and is the first dividend increase in the Company's history.

Intention to Renew Normal Course Issuer Bid

Hudbay’s board of directors has approved the renewal of the Company’s normal course issuer bid (“NCIB”) for up to 5% of the Company’s issued and outstanding common shares (“Shares”), subject to the approval of the Toronto Stock Exchange (the “TSX”). If approved by the TSX, 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 approved by the TSX, Hudbay will be authorized to acquire up to 5% of its issued and outstanding Shares, for cancellation over a 12-month period. The actual number of Shares which may be purchased by Hudbay pursuant to the NCIB, if any, 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. No purchases have been made under the current NCIB since its implementation in May 2025.

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 purchase of the Shares for cancellation may constitute a desirable use of capital and would be in the best interests of shareholders. There cannot be any assurance as to how many Shares, if any, will ultimately be purchased pursuant to the NCIB if approved by the TSX. Any subsequent renewals of the NCIB will be in Hudbay’s discretion and subject to further TSX approval.

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. 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.
