Hudbay improves copper cash cost outlook as free cash flow tops $100m

Hudbay Minerals Inc. improved its 2026 consolidated copper cash cost guidance after strong gold by-product credits and operating efficiencies helped the miner preserve attractive margins despite higher fuel and consumable costs. The Toronto Stock Exchange and New York Stock Exchange-listed company, which trades under $HBM, generated second-quarter revenue of $631.3 million, adjusted EBITDA of $321.2 million and free cash flow of $101.8 million. Hudbay maintained its production outlook for between 110,000 and 138,000 tonnes of copper and between 217,000 and 272,000 ounces of gold, while lowering expected consolidated cash costs to a range of negative $0.45 to negative $0.25 per pound of copper. The improved outlook and negative net debt position give Hudbay greater capacity to fund Copper World, Cactus and New Ingerbelle, but the next phase will test whether the company can control development spending while resolving cost and reliability pressures across Manitoba and British Columbia.

Hudbay produced 28,267 tonnes of copper and 51,234 ounces of gold during the second quarter. Net earnings attributable to owners reached $137.4 million, or $0.34 per share, while adjusted net earnings were $113.5 million, or $0.28 per share. Revenue increased from $536.4 million in the corresponding 2025 quarter, although earnings declined from the record first-quarter level because lower sales volumes reduced the benefit from stronger metal prices.

The company generated more than $200 million of free cash flow during the first half despite investing over $200 million in sustaining capital. Cash and cash equivalents stood at $890.9 million, total liquidity reached approximately $1.04 billion and net debt improved to negative $80.5 million at the end of June.

How gold by-product credits pushed Hudbay’s copper cash costs below zero

Hudbay’s consolidated cash cost, net of by-product credits, was negative $0.40 per pound of copper during the second quarter. This means the revenue generated from gold and other secondary metals was sufficient to offset the direct cash cost assigned to copper production at the consolidated level.

The result does not mean Hudbay spends nothing to mine copper. The calculation deducts revenue from gold, silver, zinc and molybdenum produced alongside copper from operating costs. Strong precious-metal prices can therefore push the reported copper cash cost below zero even while the company continues paying for labor, energy, processing, maintenance and transportation.

Gold generated approximately 38% of Hudbay’s second-quarter revenue, highlighting the importance of the company’s diversified production base. Copper remains the largest revenue source, but gold provides a valuable financial hedge by reducing effective copper costs when precious-metal prices are elevated.

Hudbay lowered its full-year consolidated cash cost guidance from negative $0.30 to negative $0.10 per pound to a new range of negative $0.45 to negative $0.25. Management said operating efficiencies and stronger gold by-product credits were more than offsetting higher expenses for fuel and consumables.

The second-quarter figure was weaker than the record negative $1.80 per pound achieved during the first quarter because lower gold production reduced by-product credits. Consolidated sustaining cash cost increased from zero to $1.39 per pound, while all-in sustaining cash cost reached $1.80 per pound.

This comparison shows why investors should not assume negative cash costs will remain fixed from quarter to quarter. Gold grades, production sequencing, metal prices and sustaining investment can cause substantial movement even when copper operations remain technically stable.

Peru remained the largest copper contributor, producing 19,446 tonnes during the quarter. Constancia’s cash cost of $1.66 per pound outperformed the lower end of its annual guidance despite planned plant maintenance, higher fuel prices and reduced gold credits following the depletion of the high-gold Pampacancha stockpile.

The Peruvian government approved an increase in Constancia’s permitted annual processing capacity from 31 million tonnes to 34 million tonnes. Hudbay is also installing pebble crushers intended to improve throughput from the third quarter and offset the effect of lower copper grades after Pampacancha’s depletion.

The combination of higher permitted capacity and processing improvements could help stabilize future copper output. Hudbay must still demonstrate that higher throughput can be achieved without sacrificing recoveries, increasing maintenance requirements or creating additional community and infrastructure costs.

Why lower sales volumes reduced profit even as copper production increased

Hudbay’s copper production increased slightly from the first quarter, but payable copper sales declined from 29,544 tonnes to 23,780 tonnes. The mismatch was partly caused by ocean swells that temporarily closed the Peruvian port and delayed shipments of approximately 10,000 dry metric tonnes of copper concentrate.

The delayed concentrate was delivered during the first half of July, meaning the issue primarily shifted revenue and cash flow between reporting periods rather than destroying production. It nevertheless reduced second-quarter revenue, adjusted EBITDA and earnings compared with the exceptionally strong first quarter.

Adjusted EBITDA declined from $421.9 million in the first quarter to $321.2 million, while net earnings attributable to owners fell from $190.4 million to $137.4 million. The decrease was driven mainly by lower sales volumes across metals and lower realized gold prices, partially offset by stronger copper prices.

Operating cash flow told a more constructive story. Cash generated from operating activities increased to $297 million from $211.3 million in the first quarter, supported partly by favorable working-capital movements. Operating cash flow before working-capital changes remained comparatively stable at $210.1 million.

The distinction matters because quarterly earnings were affected by shipment timing rather than a broad deterioration in mine performance. Hudbay’s ability to maintain more than $100 million of free cash flow while absorbing delayed sales and substantial sustaining investment supports the company’s balance-sheet improvement.

Manitoba presented a more complicated operating picture. The region produced 40,344 ounces of gold, 2,366 tonnes of copper, 4,760 tonnes of zinc and 209,478 ounces of silver, with output affected by workforce constraints, lower mined tonnes and an unplanned hoist gearbox failure at the Lalor mine.

The hoist has been repaired, and Hudbay has hired more than 100 employees while using an experienced mining contractor to advance the 1901 deposit. Management expects stronger Manitoba production during the second half as grades improve and Lalor generates more ore.

Manitoba cash cost increased to $776 per ounce of gold from $408 in the first quarter. The figure remained within the full-year guidance range, but the increase shows how workforce availability and equipment reliability can rapidly affect unit costs when production volumes decline.

Hudbay’s maintained production guidance assumes the second-half recovery proceeds as expected. Continued labor limitations or additional equipment disruptions could make the annual target more difficult, even though the current plan remains achievable.

How Copper Mountain, New Ingerbelle and Cactus could reshape Hudbay’s copper portfolio

Hudbay’s British Columbia operations produced 6,455 tonnes of copper, up from 4,821 tonnes in the first quarter, as ore mined, grades and mill throughput improved. The Copper Mountain mill processed 3.6 million tonnes, representing a 17% sequential increase.

The second semi-autogenous grinding mill reached commercial production in May and averaged approximately 12,000 tonnes per day afterward. Hudbay expects total throughput to move toward 50,000 tonnes per day during the second half once maintenance on the primary mill is completed.

Higher throughput exposed constraints in downstream grinding, contributing to lower copper and gold recoveries. British Columbia cash cost rose to $3.22 per pound, above the annual guidance range, because of higher mining costs, maintenance timing, lower by-product credits and fuel inflation.

Hudbay expects British Columbia costs to improve during the second half. Several grinding and flotation initiatives are underway, while a permanent pebble-diversion system is scheduled for commissioning during the fourth quarter.

The company has also started construction-related work at New Ingerbelle, an expansion intended to extend Copper Mountain’s mine life and improve its future copper and gold production profile. British Columbia growth capital expenditure for 2026 has increased by approximately $30 million to $115 million because of additional infrastructure costs.

That increase is manageable within Hudbay’s current liquidity, but it reinforces the need for capital discipline. Rising project costs can gradually weaken returns even when the mine extension remains strategically attractive.

Hudbay completed its acquisition of Arizona Sonoran Copper Company Inc., combining Copper World and Cactus within a larger United States development portfolio. The company expects to spend approximately $30 million at Cactus during the second half on an updated pre-feasibility study, site de-risking, exploration and ongoing project activities.

Copper World remains the most important growth decision. Mitsubishi Corporation contributed approximately $420 million when the joint venture closed in January, giving Hudbay a well-capitalized partner and reducing the amount the company must finance independently.

Hudbay has also secured $52 million of long-term municipal-bond financing that can be used for qualifying Copper World development costs. The company expects to reach a sanctioning decision later in 2026.

The strengthened balance sheet gives management the ability to advance Copper World, but financial capacity should not be confused with project certainty. The decision must still account for construction costs, permitting, water, power, copper-price assumptions and the relative returns available from Cactus, New Ingerbelle, Constancia improvements and brownfield exploration.

Hudbay now has more growth options than it can necessarily fund simultaneously without compromising returns. Its capital-allocation framework will be tested by the need to rank projects rather than approving every technically attractive development.

What the Hudbay share reaction says about copper and gold investor sentiment

Hudbay Minerals Inc. shares traded near US$21.86 on the New York Stock Exchange on July 29, up approximately 0.4% from the previous close after recovering from an intraday low of US$20.70. The muted positive movement suggests investors viewed the improved cost guidance and strong balance sheet favorably while weighing weaker quarter-over-quarter earnings and operating pressures in Manitoba and British Columbia.

The market response also reflects the fact that several of Hudbay’s strongest financial developments were already visible before the report. Mitsubishi Corporation’s Copper World investment, rising copper and gold prices and the Arizona Sonoran Copper Company acquisition had already strengthened expectations for the company’s long-term growth profile.

The second-quarter update added evidence that Hudbay can fund a larger portion of growth internally. Record trailing 12-month adjusted EBITDA of approximately $1.27 billion, negative net debt and more than $1 billion of liquidity give the company considerably greater flexibility than it held at the end of 2025.

The strongest bullish argument is that Hudbay offers exposure to both copper scarcity and elevated gold prices while maintaining a pipeline of long-life projects in the Americas. Gold credits reduce current copper costs, while Copper World, Cactus, New Ingerbelle and Constancia optimization could expand future copper production.

The more cautious view is that the company is entering a capital-intensive period while several operations still require performance improvements. Copper Mountain must restore recoveries and lower costs, Manitoba must increase ore output, and management must prevent concurrent growth projects from overwhelming construction and financial controls.

Hudbay has created the balance-sheet capacity to grow. The investment outcome will now depend on whether that capital is directed toward projects that increase per-share value rather than simply expanding the company’s asset base.
