Nexa Resources Reports Strong 3Q25 Results with Net Income of US$100 Million

Luxembourg, Luxembourg--(Newsfile Corp. - October 30, 2025) - Nexa Resources (NYSE: NEXA), one of the world's leading zinc producers, reported net income of US$100 million in 3Q25, compared to US$13 million in 2Q25 and US$6 million in 3Q24. The sequential improvement was primarily driven by a non-cash impairment reversal at Cerro Pasco and stronger operational margins, partially offset by a 3% appreciation of the Brazilian real against the U.S. dollar. Adjusted net income was US$27 million for the quarter.

Adjusted EBITDA of US$186 million increased from US$161 million in 2Q25 and US$183 million in 3Q24. The sequential improvement was primarily driven by higher mining output, increased smelting sales volume, a higher by-products contribution (except for copper), and better prices for all metals. The year-over-year performance also reflects a stronger by-products contribution, partially offset by lower treatment charges ("TCs") and higher maintenance-related operational costs.

Net revenues reached US$764 million, up 8% from US$708 million in 2Q25 and US$709 million in 3Q24, supported by the same drivers of higher smelting sales volume, ongoing operational improvements, and favorable metal prices.

"Nexa delivered another quarter of strong financial and operational performance, as higher mining output and supportive metal prices led to increased Net revenues, Adjusted EBITDA and free cash flow, reflecting the consistent evolution of our execution capacity and our disciplined capital allocation," said Ignacio Rosado, CEO of Nexa. "Aripuanã achieved its highest zinc production since the start of its ramp-up, a direct result of more stable operations and higher throughput. Additionally, the advancement of Phase I of our Cerro Pasco Integration Project and continued exploration investment are reinforcing the foundation for Nexa's long-term growth."

Disciplined Financial Management

• CAPEX totaled US$90 million in 3Q25, primarily allocated to sustaining investments, including mine development and operational maintenance. Of this amount, approximately US$12 million was invested in Phase I of the Cerro Pasco Integration Project. Total consolidated CAPEX for the full-year 2025 guidance remains unchanged at US$347 million.
• At the end of 3Q25, Nexa's net debt totaled US$1,479 million (from US$1,515 million at the end of 2Q25), driving an improvement in the Net debt/LTM Adjusted EBITDA ratio to 2.2x (from 2.3x in the previous quarter).

Operational and Project Highlights

Mining operations showcased strength and recovery, smelting operations hit record volumes, and the Cerro Pasco Integration Project advanced on track, underscoring Nexa's solid operational performance and progress in its key strategic initiatives.

Mining

• Overall zinc production rose 14% quarter-over-quarter and 1% year-over-year to 84kt, mainly driven by stronger performances at Vazante, Aripuanã, and El Porvenir, partially offset by lower output at Cerro Lindo.
• Aripuanã achieved a record quarterly zinc production of 10.4kt, up 39% from 7.5kt in 3Q24 and 70% from 6.1kt in 2Q25, driven by improved plant stability and operational optimization.
• Vazante and El Porvenir also posted increased quarterly production as they recover from operational challenges faced in the first half of the year.
• Turning to other metals, lead production increased 16% quarter-over-quarter and 3% year-over-year to 18kt, supported by higher output across most mines. Copper production decreased 6% quarter-over-quarter and 8% year-over-year to 9kt, primarily due to lower output at Cerro Lindo. Silver production totaled 2.9 million ounces, up 8% quarter-over-quarter and broadly stable year-over-year.

Smelting

• Zinc metal and oxide production totaled 147kt, up 6% quarter-over-quarter, driven by record output at the Cajamarquilla smelter and an operational recovery at Três Marias. Year-over-year, production decreased 4%, consistent with 2025 guidance, which reflects lower availability of third-party concentrates amid reduced treatment charges (TCs).
• Zinc metal and oxide sales totaled 150kt, up 3% from the prior quarter, demonstrating Nexa's ability to convert operational improvements into commercial delivery. Year-over-year, sales declined 2%, impacted by lower zinc oxide output at Três Marias.

Projects

• Nexa continues to progress on Phase I of the strategic Cerro Pasco Integration Project. Construction, which began in July, is on schedule with earthworks, slope cutting, and containment work well underway. Key equipment packages are manufactured and undergoing Factory Acceptance Tests, keeping the project on track for 2026 commissioning. This project is critical to extending the life-of-mine of the complex and improving long-term efficiency.
• Nexa remains committed to enhancing free cash flow generation through disciplined capital allocation, prioritizing sustaining investments, brownfield mineral exploration, gross debt reduction, and critical ESG and HS&E initiatives. The company continues to focus on optimizing its most attractive assets and projects to strengthen operational resilience and create long-term value.
