Ero Copper (ERO) Q2 2026 earnings review
Massive Cash Flow Unlocks Premature Deleveraging Target
Ero Copper delivered a highly lucrative Q2, propelled by a 170% QoQ surge in gold production and the continued ramp-up of the Tucumã copper operation. While Net Income slightly decelerated to $89.5M from $108.8M in Q1, Operating Cash Flow exploded 49% QoQ to $137.9M. This windfall—heavily aided by the seasonal dry-weather processing of the Xavantina gold stockpile—allowed Ero to aggressively pay down debt. Net leverage dropped to 0.8x, comfortably piercing management's 1.0x target and paving the way for eventual shareholder returns. The primary blemish remains cost inflation, forcing an upward revision to Xavantina's cost guidance.
🐂 Bull Case
Net leverage fell to 0.8x (beating the <1.0x target) as net debt dropped $38M QoQ to $452.7M. The balance sheet is now primed for the next phase of capital allocation, which management previously indicated would include shareholder returns.
The dry season unlocked the Xavantina historic gold concentrate stockpile. 11,860 ounces were recovered at a phenomenal C1 cash cost of just $633/oz, generating immediate, ultra-high-margin cash flow.
🐻 Bear Case
Inflation and a strong BRL are eroding margins. Xavantina's mined gold C1 cost guidance was raised by $100/oz at the midpoint, and Caraíba's C1 copper costs remain elevated at $2.76/lb compared to $2.07/lb a year ago.
Caraíba's processed grade fell to 0.87%, down from 0.93% in Q1 and 1.27% a year ago, muting the impact of otherwise strong mill throughput.
⚖️ Verdict: 🟢
Bullish. The aggressive execution of the deleveraging strategy outweighs near-term unit cost inflation. With the Tucumã ramp-up stabilizing and the Xavantina stockpile delivering high-margin ounces, cash generation is accelerating.
Key Themes
Historic Stockpile Drives Margin Windfall
Xavantina's gold production skyrocketed 170% QoQ to 20,553 ounces. The primary catalyst was the transition into the dry season, which allowed the recovery of 11,860 ounces from historic gold concentrate stockpiles (up from just 2,112 ounces in Q1). At a C1 cash cost of $633/oz, this material is generating massive free cash flow and driving the rapid balance sheet deleveraging.
Xavantina Cost Guidance Hiked on Low Volumes
A clear red flag emerged at Xavantina's core mining operations. Management updated Mined Gold C1 cash cost guidance to $1,100-$1,350/oz (from $1,000-$1,250/oz) and AISC to $2,200-$2,700/oz (from $2,000-$2,500/oz). This deterioration is directly tied to mined production tracking at the low end of the 40,000-50,000 oz guidance range, exposing the operation to negative fixed-cost leverage.
Tucumã Tailings Expansion Advances
Technological and infrastructure debottlenecking continues at Tucumã. The company completed a planned expansion of the existing tailings filtration system at the end of Q2, boosting capacity by ~8%. Further modular filters are expected in H2 2026. This hardware addition is a structural driver that will allow sustained higher throughput rates, buffering against lower planned copper grades.
Caraíba Grade Dilution Weighs on Unit Costs
Caraíba's C1 cash costs remain stubbornly high at $2.76/lb (vs $2.07/lb in Q2 2025). While management points to BRL strength and inflation, a fundamental issue is the steep drop in processed copper grade—falling to 0.87% in Q2 2026 from 1.27% a year ago. Even with record plant throughput, lower grades are severely capping margin expansion.
FX Hedging and OneEro Program Offset Macro Headwinds
Management's proactive risk mitigation is paying off. The FX collar program generated $12.7M in realized gains in Q2 ($19.9M YTD), successfully insulating operating cash flows from a strengthening BRL. Simultaneously, the 'OneEro' strategic program locked in $10-$15M in annualized supply savings and negotiated new smelting terms expected to save >$20M in 2026, buffering the macro inflationary shock.
Other KPIs
Accelerating. Up 15% sequentially from $125.2M in Q1 2026 and up 74% YoY from $82.7M in Q2 2025. The beat was driven by high-margin gold sales from the historic stockpile and steady copper volumes, overcoming sequential cost creep.
Accelerating. Increased by $35.5M QoQ. Comprised of $101.7M in cash and $80.0M undrawn on the revolving credit facility. The company repaid $25.0M on the revolver subsequent to quarter-end, bringing 2026 repayments to $60.0M.
Guidance
Stable. Guidance is maintained, implying a back-half weighted year. Caraíba expects higher throughput and processed grades in H2, while Tucumã expects sustained higher throughput to offset lower planned grades.
Stable. Guidance maintained, but management explicitly noted that if current BRL strength and inflation persist, there is a potential incremental impact of ~$0.10/lb. Costs are expected to decelerate (improve) in H2 due to higher planned production.
Accelerating. Raised from the previous range of $275 - $320 million. The $10M increase is entirely allocated to the Xavantina Operations to fund a new powerline, intended to reduce long-term power transmission rates.
Key Questions
Shareholder Return Timeline
With the net debt leverage ratio dropping to 0.8x—comfortably piercing your 1.0x target—what are the remaining hurdles before initiating the shareholder return program, and will it bias toward dividends or buybacks?
Caraíba Grade Trajectory
Caraíba's processed grades fell to 0.87% this quarter. Is this purely a function of planned mine sequencing in the upper levels of Pilar and Surubim, or are you seeing higher-than-expected dilution?
Tucumã Tailings Filtration Capacity
You noted the recent ~8% capacity expansion at Tucumã is not included in 2026 guidance. How much incremental daily throughput could the H2 modular filter installations unlock by year-end?
Stockpile Gold Sustainability
At 11,860 ounces recovered in Q2, how many dry-season quarters remain before the historic gold concentrate stockpile at Xavantina is fully exhausted?
