Nexa Resources (NEXA) Q1 2025: Zinc Production Declines 23% Amid Weather Challenges, Yet Strategic Projects and Cost Discipline Support Outlook

Nexa Resources navigated significant operational headwinds in Q1 2025, with zinc production falling 23 percent due to atypical rainfall and smelter instabilities. Despite this, disciplined cost management and progress on the Cerro Pasco integration project underpin a resilient adjusted EBITDA and a reaffirmed full-year guidance.

Summary

  • Operational Resilience Amid Weather Disruptions: Heavy rainfall and geotechnical issues constrained zinc output across key mines.
  • Strategic Project Advancement: Cerro Pasco integration progresses on schedule, supporting long-term asset life extension.
  • Financial Discipline Maintained: Liability management and cost control sustain margins despite volume pressures.

Business Overview

Nexa Resources is a diversified mining company primarily engaged in the extraction and processing of zinc, copper, lead, and silver. Its operations are segmented into mining and smelting activities, with mining focused on metal concentrate production and smelting on refining zinc metal and oxide. The company’s revenue is driven by metal prices, production volumes, and treatment charges (TCs), with major assets located in Peru and Brazil.

Performance Analysis

In Q1 2025, Nexa's zinc production totaled 67,000 tons, a 23 percent decline year-over-year and an 8 percent drop quarter-over-quarter. This decline was primarily attributed to atypical heavy rainfall in the Pasco region impacting El Porvenir and Atacocha mines, as well as operational constraints at Aripuanã and geotechnical issues at Vazante. Smelting volumes also contracted by 4 percent year-over-year and 12 percent quarter-over-quarter, reflecting lower output at Brazilian smelters and continued market volatility.

Despite the volume headwinds, net revenues increased 8 percent year-over-year to $627 million, driven by higher London Metal Exchange (LME) zinc and copper prices, which rose 16 and 11 percent respectively. However, compared to Q4 2024, revenues declined 15 percent due to lower smelting sales volumes and softer zinc and lead prices. Adjusted EBITDA was $125 million, slightly down from $128 million a year prior and $197 million in the previous quarter, reflecting higher costs and reduced sales volumes, especially in the smelting segment.

  • Cost Dynamics: Mining cash costs improved to $0.11 per pound from $0.26 a year ago, aided by higher by-product credits and favorable foreign exchange, though quarter-over-quarter costs increased due to reduced zinc volumes.
  • Working Capital Impact: A seasonal working capital outflow of $265 million contributed to a negative free cash flow of $226 million, reflecting tax payments and supplier settlements.
  • Leverage and Liquidity: Net debt to adjusted EBITDA increased to 2.1 times from 1.7 times last quarter, driven by working capital seasonality, with liquidity remaining robust at $721 million.

Overall, the quarter’s financial results illustrate Nexa’s ability to sustain profitability amid operational disruptions and commodity price volatility, supported by disciplined cost control and strategic capital allocation.

Executive Commentary

"We continue to see a strong medium and long-term fundamentals for zinc, copper, and other key metals, supported by demand drivers like infrastructure, development, and industrial revitalization. Despite operational challenges primarily due to heavy rainfall and smelter instabilities, we delivered resilient adjusted EBITDA demonstrating the strength of our integrated business model and cost discipline."

Ignacio Rosado, CEO

"Our net debt to adjusted EBITDA ratio increased due to seasonal working capital effects, which we expect to reverse throughout the year. We maintain a healthy liquidity position and have successfully extended our debt maturity profile through a $500 million bond issuance, underpinning our financial flexibility."

José Carlos del Valle, CFO

Strategic Positioning

1. Operational Stability and Production Recovery

Nexa is actively addressing production shortfalls caused by weather and geotechnical issues. The heavy rainfall in the Pasco region, which was about 30 percent above historical averages, impacted treated ore volumes and plant uptime, particularly at El Porvenir, Atacocha, and Aripuanã. The company expects recovery in the second quarter as the rainy season ends and operational improvements take hold, including the installation of a fourth tailings filter at Aripuanã scheduled for Q1 2026.

2. Cerro Pasco Integration Project Advancement

The Cerro Pasco integration project, a multi-phase initiative to extend mine life and improve operational efficiency, is progressing on schedule. Phase one, focused on tailings pumping and piping systems, is set to commence construction in Q2 2025. This project aims to significantly expand tailings storage capacity and unlock higher-grade underground resources, enhancing operational flexibility and long-term value.

3. Cost Management and Cash Flow Focus

Despite volume declines, Nexa maintained tight cost control, with mining cash costs improving year-over-year due to higher by-product credits and exchange gains. The company is implementing initiatives to optimize working capital and reduce operational expenses, aiming to restore positive free cash flow in subsequent quarters. Sustaining capital expenditures remain prioritized, with $50 million invested in Q1, mainly for mine development and maintenance.

4. Liability Management and Capital Structure Optimization

In April 2025, Nexa executed a $500 million 12-year bond issuance at a 6.6 percent coupon, alongside tender offers repurchasing a large portion of 2027 and 2028 notes. This extended the average debt maturity from 5.3 to approximately 8 years, enhancing financial flexibility and reducing near-term refinancing risk. The company remains committed to deleveraging and maintaining a capital structure aligned with the long life of its assets.

5. Market and Tariff Risk Monitoring

Nexa is closely monitoring geopolitical and tariff developments, particularly U.S. import tariffs. Currently, zinc is exempt from tariffs on imports from Peru, and Nexa supplies about 8 percent of U.S. zinc demand. While tariff risks remain uncertain, the company believes demand will persist barring a recession. Treatment charges remain low, pressuring smelter margins, but the company expects market adjustments that could support prices and supply stability in the medium term.

Key Considerations

The first quarter results reflect a complex interplay of operational disruptions, market volatility, and strategic initiatives. Investors should weigh the following:

  • Production Volatility: Weather and geotechnical issues caused significant zinc output declines, but management expects recovery in the second half of 2025.
  • Cost Efficiency Gains: Improved mining cash costs partially offset volume declines, highlighting operational discipline.
  • Working Capital Seasonality: Negative working capital impacted free cash flow, with tax-related one-off payments contributing substantially.
  • Strategic Project Execution: Progress on the Cerro Pasco project supports longer mine life and potential higher-grade ore access.
  • Financial Flexibility: Extended debt maturities and strong liquidity position Nexa to navigate ongoing market uncertainties.

Risks

Key risks include continued operational disruptions from weather or geotechnical challenges, volatility in metal prices and treatment charges, geopolitical tensions affecting tariffs and supply chains, and the potential for a global economic slowdown impacting demand. These factors could pressure margins, cash flow, and production volumes.

Forward Outlook

For Q2 2025, Nexa anticipates zinc production to improve, with Cerro Lindo expected to maintain or slightly increase output, El Porvenir and Atacocha to benefit from higher-grade zones and volume increases, and Aripuanã to see gains supported by the dry season and filter performance improvements. Smelting sales volumes are expected to remain stable in Peru and Brazil, reflecting ongoing operational challenges. Capital expenditures for 2025 remain guided at $347 million, with exploration and project evaluation at $88 million. The company expects working capital to normalize, supporting improved cash flow and stable leverage by year-end.

Takeaways

Nexa’s Q1 2025 results underscore the operational challenges posed by adverse weather and technical issues, yet the company’s integrated business model, cost discipline, and strategic investments provide a solid foundation for recovery and growth. The ongoing Cerro Pasco integration project is a critical long-term value driver, while financial prudence through liability management enhances resilience amid market volatility. Investors should monitor production recovery, treatment charge trends, and tariff developments as key indicators of near-term performance and risk.

  • Operational Recovery Trajectory: The resolution of weather-related disruptions and filter upgrades at Aripuanã will be pivotal to meeting full-year production guidance.
  • Strategic Capital Allocation: Continued investment in Cerro Pasco and exploration supports asset longevity and potential resource expansion.
  • Market Sensitivity: Treatment charges and zinc prices remain critical levers affecting smelter profitability and overall margin sustainability.

Conclusion

Nexa Resources delivered a challenging first quarter marked by significant production headwinds but maintained financial discipline and advanced key strategic projects. The company’s reaffirmed guidance and proactive liability management position it well to navigate the volatile market environment and capitalize on long-term growth opportunities.
