Business Overview
Nexa Resources is a vertically integrated mining and smelting company primarily focused on zinc, lead, copper, and silver production in Peru and Brazil. The company operates through mining and smelting segments, generating revenue from metal concentrate sales and refined metal products, with by-products such as silver and gold contributing to overall margins. Nexa’s business model leverages its integrated mine-smelter platform to mitigate market volatility and optimize returns.
Performance Analysis
In Q2 2025, Nexa reported net revenues of $708 million, up 13 percent sequentially, driven by increased zinc sales volumes and stronger prices for silver, copper, and lead. Adjusted EBITDA rose 28 percent quarter-over-quarter to $161 million, reflecting improved operational performance and favorable by-product contributions, despite a 7 percent decline in zinc prices. The mining segment’s adjusted EBITDA increased notably to $135 million, supported by higher zinc production and by-product sales, offsetting lower zinc prices. Conversely, the smelting segment experienced a decline in adjusted EBITDA to $25 million due to increased operational costs and lower treatment charges, although sales volume improved 12 percent sequentially.
Operationally, zinc production reached 74,000 tons, a 9 percent increase from Q1, mainly from Peruvian operations recovering from earlier disruptions. However, production remains 12 percent below Q2 2024 levels, with challenges at Vazante and Aripuanã impacting output. Consolidated mining cash costs improved significantly to negative $0.11 per pound of zinc, benefiting from higher by-product credits and operational efficiencies. Smelting conversion costs increased 19 percent quarter-over-quarter, reflecting maintenance and input cost inflation, while cash costs rose modestly to $1.23 per pound. The company’s working capital management efforts yielded a positive $3 million impact in Q2, reversing prior quarter deficits and contributing to positive free cash flow of $17 million.
- Production Recovery: Zinc output increased 9 percent sequentially, led by Peruvian mines, signaling operational stabilization.
- Cost Dynamics: Mining cash costs improved due to by-product contributions and lower treatment charges, while smelting costs rose amid maintenance and input inflation.
- Financial Flexibility: Liability management extended debt maturities to 7.7 years and enhanced liquidity to $738 million, supporting investment-grade credit metrics.
These results underscore Nexa’s resilience amid market volatility and operational headwinds, positioning the company for improved second-half performance supported by ongoing capital projects and exploration success.
Executive Commentary
"We reported net revenues of $708 million, up 13 percent compared to the first quarter of 2025, and adjusted EBITDA of $161 million, a 28 percent sequential increase. This performance reflects higher sales volumes, especially in our smelting segment, and the benefit of stronger by-product prices. Our free cash flow was $17 million, an improvement over the previous quarter, supported by better working capital management."
Ignacio Rosado, Chief Executive Officer
"Our priorities continue to be the ones we have mentioned before as part of our capital allocation framework. Obviously, extending the life of our mines, so investing in our own operating units, which is the most efficient way of using our capital. Then reducing gross debt. We would like to have a lower leverage level that gives us more of a buffer to go through different cycles and also to recover some of the financial flexibility that we had in the past, also thinking about what growth opportunities that we may have in the future."
José Carlos del Valle, Chief Financial Officer
Strategic Positioning
1. Operational Stabilization at Aripuanã and Vazante
Aripuanã’s operational challenges due to excessive rainfall and tailings filter capacity constraints led to downtime and production disruptions in Q1 and early Q2. The company undertook refurbishment and maintenance of three existing tailings filters, which are now fully operational, delivering more stable production in July and beyond. The fourth tailings filter, currently in fabrication, is on track for delivery and installation in H2 2025, with commissioning anticipated in Q1 2026. Vazante faced geotechnical challenges with a pillar collapse limiting access to high-grade zones, prompting cautious mining to ensure safety and preserve long-term resource potential. Both assets are expected to improve production in H2 2025, supporting the company’s revised guidance.
2. Cerro Pasco Integration Project Advancing
The Cerro Pasco integration project is a core growth initiative aimed at extending mine life and improving margins through infrastructure enhancements. Phase 1, focusing on tailings pumping and piping systems, achieved key milestones including final engineering, permitting, equipment procurement, and site mobilization. Construction activities commenced in July, with Phase 2 technical assessments progressing as planned. This project underpins Nexa’s long-term value creation by expanding tailings storage capacity and enabling future production increases.
3. Exploration Success Reinforcing Resource Base
Nexa’s exploration program delivered encouraging results across multiple assets, including Cerro Lindo, Aripuanã, Basante, and Cerro Pasco. Drilling confirmed extensions of mineralized zones near existing infrastructure, enhancing confidence in life-of-mine extensions. The company emphasized ongoing conversion of resources into reserves, particularly at Aripuanã, where a 15-year mine life is supported by substantial resource upside. These efforts align with Nexa’s strategy of portfolio optimization and sustainable production growth.
4. Financial Strength and Liability Management
Nexa successfully executed a $500 million 12-year bond issuance with a 6.6 percent coupon, enabling full redemption of 2027 notes and significant repurchases of 2028 notes. This liability management extended average debt maturity to 7.7 years and improved liquidity to $738 million, including an undrawn $320 million sustainability-linked revolving credit facility. Despite a slight increase in net debt to adjusted EBITDA ratio to 2.3 times, the company remains focused on deleveraging and maintaining an investment-grade credit profile.
5. Cost Discipline Amid Inflationary Pressures
While mining cash costs improved due to operational efficiencies and by-product credits, smelting conversion costs rose 19 percent quarter-over-quarter, driven by maintenance, third-party services, and input cost inflation. Nexa’s application of a three-year rolling average for treatment charges (TCs) limits exposure to spot market volatility, with only 30 percent of concentrate purchases subject to 2025 benchmark TCs. The company continues to prioritize cost control initiatives to protect margins in a challenging pricing environment.
Key Considerations
Nexa’s Q2 results reflect a balance between operational recovery and ongoing challenges, with several factors shaping near-term and long-term prospects.
