Ero Copper’s latest earnings call struck a notably upbeat tone, with management emphasizing record quarterly revenue and EBITDA alongside multiple production records across its copper and gold operations. While executives acknowledged cost pressures, logistics challenges and some operational hiccups, the overarching message was one of accelerating momentum, balance sheet improvement and a strengthened long-term growth runway.
Furnas PEA Delivers Strong Long-Term Growth Engine
The newly released Preliminary Economic Assessment for the Furnas project stood out as the strategic centerpiece, outlining a 24-year mine life with more than 1.2 million tonnes of copper, 2 million ounces of gold and 9 million ounces of silver. Over the first 15 years, the mine is expected to average roughly 70,000 tonnes of copper, 111,000 ounces of gold and over 500,000 ounces of silver per year at first-quartile C1 cash costs of about $0.24 per pound.
Record Q4 Operational Performance Across Core Assets
Operationally, Ero reported its best quarter yet at several mines, led by the Caraíba complex where mill throughput nearly hit 1.2 million tonnes in Q4, up 18% sequentially, driving a 15% jump in copper output. Tucumã also posted a record quarter with copper production rising 22% versus Q3, while Xavantina’s output surged 53% as the mine’s mechanization program gained traction.
Gold Concentrate Strategy Boosts Xavantina Economics
At Xavantina, the company’s gold concentrate program is emerging as a meaningful value lever, delivering around 15,000 incremental ounces of gold in Q4 alone. Including mine production, Xavantina produced roughly 20,000 ounces in the quarter and over 50,000 ounces for 2025, and management expects concentrate sales to continue through 2026, albeit with a seasonal pattern.
Revenue Records and Strong Margin Expansion
On the financial front, Ero booked record quarterly revenue of $320 million in Q4, an increase of $143 million versus Q3, representing about 81% growth. Adjusted EBITDA rose to $186.7 million in the quarter and $409.7 million for the year, with adjusted net income reaching $108.4 million in Q4 and $220.4 million for the full year, translating to earnings per share of $1.04 and $2.12 respectively.
Liquidity Strengthens as Leverage Trends Lower
The company also highlighted a healthier balance sheet, finishing the quarter with total liquidity of $150.4 million, including $105.4 million in cash and $45 million of undrawn credit. Net debt declined to about $502 million from $545 million in Q3, improving net debt to EBITDA to 1.2 times, and management reiterated its goal of pushing leverage below 1.0 times before initiating capital returns.
2026 Production Outlook and Exploration Upside
Looking ahead to 2026, Ero guided consolidated copper production to a range of 67,500 to 77,500 tonnes, with volumes weighted toward the second half as Q1 is expected to be the softest quarter. Xavantina mine production is forecast at 40,000 to 50,000 ounces of gold, while the company plans roughly 50,000 metres of exploration drilling, largely at Furnas, as capital spending moderates with major builds past peak.
Lower Gold Cash Costs and Ongoing Efficiency Gains
The company reported a roughly 29% quarter-on-quarter drop in gold C1 cash costs in Q4, reflecting both higher volumes and efficiency gains at Xavantina. Management signaled confidence in sustaining Q4’s operational performance into 2026, pointing to additional low-cost improvement projects such as magnetite recovery and gravity pre-concentration to further lift byproduct revenue and margins.
Operational Disruption and Mill Liner Issue at Tucumã
Despite the strong production figures, Tucumã experienced extended unplanned downtime in December tied to an OEM wear-part quality issue, which pulled about 10 days of maintenance originally slated for Q1 into Q4. The accelerated expensing of unamortized mill liners pushed Tucumã’s C1 cash costs higher by roughly $0.10 per pound in the quarter, temporarily masking the mine’s underlying cost profile.
Transport and COP30-Related Costs Pressure Copper Margins
Tucumã also faced elevated transportation, demurrage and port charges connected to COP30-related activity in Pará State, which added about $0.10 per pound to its C1 costs. These pressures helped drive a roughly 1.5% quarter-on-quarter increase in consolidated C1 copper cash costs in Q4, underscoring how regional logistics and event-driven factors can weigh on margins even in strong operating quarters.
Seasonal Weather Limits Gold Concentrate Shipments
The company cautioned that Brazil’s rainy season, particularly in Mato Grosso from November through March or April, materially limits drying capacity and gold concentrate shipments at Xavantina. Management expects only modest concentrate sales in Q1 2026, noting that unusually heavy rains this year have slowed stockpile processing and are likely to shift more sales and cash flow into the second and third quarters.
Furnas Resource Density and Conversion Risk Remains
While the Furnas PEA economics are compelling, management flagged resource and drill-density uncertainty as a key risk that investors should monitor. Only 28,000 metres of the 50,000 metres drilled last year were incorporated into the PEA, and roughly 60% of the material in the study is currently classified as Inferred, meaning more infill drilling is required to upgrade resources to Measured and Indicated for the next study phase.
Contract and Currency Headwinds Temper Upside
Ero also described market and contract headwinds, noting that Tucumã faces higher treatment and refining charges per pound due to its lower concentrate grade and longer haul distance versus Caraíba. The company’s long-term contracts limit its ability to quickly benefit from improving TC/RC benchmarks, while the Brazilian real has moved unfavorably against internal budget assumptions, creating incremental cost pressure.
Leverage Targets and Revolver Repayment Still in Focus
Despite notable progress on deleveraging, management emphasized that net debt of about $502 million and net debt to EBITDA of 1.2 times still leave some balance sheet risk if markets soften. The company plans to fully repay the $155 million drawn on its revolving facility in 2026, and made clear that returning capital to shareholders will only begin once leverage is below 1.0 times and the revolver is paid down.
Forward Guidance Highlights Growth, Efficiency and Deleveraging
Ero’s forward-looking guidance centers on maintaining Q4’s strong operating baselines, including near 3.0 million tonnes of consolidated throughput at average copper grades of about 1.3% to 1.4% in 2026. Management underscored the potential upside from near-term projects not baked into formal guidance, such as additional tailings filtration at Tucumã and ventilation upgrades at Xavantina, while reaffirming its plan to drill aggressively at Furnas and steadily delever the balance sheet.
Ero Copper’s earnings call painted a picture of a miner moving from build-out to harvest mode, with record production, expanding margins and a clear path to lower leverage reinforcing investor confidence. While cost and logistical headwinds, plus Furnas resource conversion risk, remain watchpoints, the combination of strong near-term cash flow and a highly economic growth pipeline framed a constructive outlook for the company’s shares.
