Nexa posts US$98M 2Q26 net income; US$286M adj. EBITDA

Adjusted EBITDA increased 78% year-over-year on higher mining and smelting results.

Aripuanã commissions and starts up fourth tailings filter.

Cerro Lindo silver streaming stepdown became effective in May, supporting stronger cash generation going forward.

Luxembourg, Luxembourg--(Newsfile Corp. - August 5, 2026) - Nexa Resources S.A. (NYSE: NEXA), one of the world's largest zinc producers, today reported net income for the second quarter of 2026 of US$98 million, compared to US$13 million in 2Q25 and US$118 million in 1Q26. Adjusted EBITDA reached US$286 million, up 78% year-over-year, while net revenues totaled US$908 million, up 28% year-over-year.

The year-over-year improvement was primarily driven by higher zinc prices, a stronger contribution from by-products, a higher share of zinc concentrate sourced from Nexa's own mines and lower operating costs. The recovery of Peruvian operations also supported improved mining performance during the quarter, with treated ore volumes increasing 11% sequentially.

The quarter also marked two important operational milestones for Nexa. At Aripuanã, the company commissioned its fourth tailings filter and ended June at 86% average capacity utilization. At Cerro Lindo, Nexa started up block caving operations at the end of the second quarter, reaching regular operation in July - the first application of this mining method at the company. As the caving footprint expands, Nexa expects to lower unit costs, improve access to higher-grade copper areas and further enhance safety through reduced risk exposure.

At Cajamarquilla, operations returned to normal levels in June following the May fire incident, while zinc cathode production continued throughout the restoration process. The company expects to recover the affected volumes in the second half of the year, and its 2026 guidance for mining production, smelting sales, costs, CAPEX, and exploration, project evaluation, and other expenses remains unchanged.

During the quarter, Nexa reached the delivery threshold under the Cerro Lindo silver streaming agreement, reducing the streamed share of production from 65% to 25%, effective in May. The stepdown represents a recurring improvement in cash generation from an asset already owned by the company, with no incremental capital required, and is expected to contribute to stronger future results.

Commenting on the results, Ignacio Rosado, CEO of Nexa, said: "The zinc concentrate market remains tight, with spot TCs in China deep in negative territory. The same conditions that pressure merchant smelters support our mining segment, and our own feed and by-product credits cushion the rest. Our mines supplied 54% of smelter feed in the quarter. This is the value of an integrated portfolio through the cycle."

In July, Votorantim and Boliden publicly confirmed discussions regarding a potential acquisition of Votorantim's controlling stake in Nexa. As of the date of this release, whether any agreements, including any agreements involving the company, will be entered into in connection with a potential transaction, and the timing and terms of any such agreements remain uncertain.

"Our responsibility is unchanged: to operate our assets in Brazil and Peru to the highest standards, prioritizing safety, operational excellence, sustainability, innovation, and responsible production while ensuring long-term value is preserved for our shareholders. That is what our results for this quarter reflect, and it is what we will continue to strive for in the second half of the year," stated Mr. Rosado.

Operational Highlights

Mining: zinc production reached 79kt, up 8% year-over-year on higher grades, and broadly stable sequentially. Lead production increased 2% both year-over-year and quarter-over-quarter to 15kt. Copper production declined 31% year-over-year and 2% quarter-over-quarter to 6.3kt, reflecting lower head grades at Cerro Lindo and Aripuanã. Silver production totaled 2.7 million ounces, up 1% year-over-year and 17% quarter-over-quarter, supported by the recovery of our Peruvian operations from 1Q26 setbacks.

Smelting: zinc metal and oxide production totaled 125kt, down 10% year-over-year and 15% quarter-over-quarter, while sales reached 134kt, down 7% year-over-year and 8% quarter-over-quarter, primarily reflecting the temporary suspension of operations at Cajamarquilla following the May fire incident.

By-products: sulfuric acid production increased 9% year-over-year to 202kt, driven by higher throughput of sulfide concentrate. Silver content sales rose 22% to 468koz, primarily on higher silver content in the concentrate feed and recovery improvements at Cajamarquilla, alongside the consumption of calcine inventory with higher silver content at Juiz de Fora. Copper cement sales increased 38% to 2.8kt.

Capital Allocation and Balance Sheet

CAPEX totaled US$89 million in 2Q26, up 24% quarter-over-quarter and 3% year-over-year, primarily reflecting higher mine development investments and accelerated project disbursements. Spending was directed mainly toward mine development and Tailings Storage Facilities, including US$9 million invested in Phase I of the Cerro Pasco Integration Project. Nexa's 2026 CAPEX guidance of US$381 million remains unchanged.

Net leverage measured by the net debt to LTM Adjusted EBITDA ratio, improved to 1.40x, compared to 1.59x in 1Q26 and 2.28x in 2Q25, primarily driven by stronger last twelve months ("LTM") Adjusted EBITDA of US$1,055 million. Net debt was broadly stable quarter-over-quarter and down 3% year-over-year.

Cerro Pasco Integration Project

Nexa completed the main civil works of Phase I during the quarter and advanced to the electromechanical assembly stage, including installation of the tailings thickener. All main equipment has been manufactured, tested and remains available according to the project sequence.

Following a review of the project's long-term configuration, Nexa increased the total estimated CAPEX for the Cerro Pasco Integration Project from US$138 million to US$180 million. The more favorable metal price environment supported a reassessment of certain operating parameters at the Atacocha open pit mine, including the review of economically mineable areas, which are expected to enable the extension of the open-pit operation beyond previous expectations. This led to a revised development sequence for tailings and waste storage facilities. The revised scope also incorporates geomembrane lining, which was not part of the original design and strengthens the project's environmental and regulatory risk profile. CAPEX guidance for the project in 2026 remains unchanged, with the incremental investment allocated to 2027 and subsequent years.

Completion of the tailings pumping system is now expected in 1Q27, compared with 4Q26 previously, reflecting adjustments to the construction sequence and space constraints at the site, while the start of pumping operations is expected in early 3Q27. Following completion of the tailings pumping system, Nexa will begin the process of obtaining operating authorization from Peru's General Directorate of Mining – Ministry of Energy and Mines (DGM-MINEM).

The second Environmental Impact Study Modification (MEIA) for El Porvenir and the third MEIA for Atacocha remain under evaluation by SENACE, with approvals still expected in 1Q27.

ESG and Corporate Highlights

In 2Q26, Nexa advanced key initiatives across safety, innovation, sustainability, community engagement and corporate governance. The company strengthened operational risk controls and accelerated the adoption of automation and artificial intelligence across its operations, while progressing circular economy projects aimed at creating value from industrial residues. Nexa also expanded its engagement with local communities, reinforced governance and risk management practices, and maintained its commitment to transparency, responsible production and long-term value creation.

Safety & Operational Excellence

The company concluded the investigation into the Três Marias event and implemented improvements covering maintenance procedures, hot work controls, workforce training and operational planning. The investigation into the Cajamarquilla fire remains ongoing, with measures focused on the safe resumption of operations.

At Cerro Lindo, Nexa centralized underground blasting through remote operation from a surface control room. The block caving operation is supported by equipment automation, remote operation and real-time geotechnical instrumentation, which further reduce personnel exposure in production and caving zones.

Innovation & Circular Economy

Nexa advanced several circular economy initiatives during the quarter, including the pyrite commercialization project in Peru, the development of Waelz Aggregate for road paving applications, and initiatives in Brazil to convert industrial residues into agricultural inputs.

The company also expanded the use of artificial intelligence in its operations through the AI Vazante project, focused on flotation optimization, and finalized development of an AI-based automated process control model at Cajamarquilla aimed at improving process stability and increasing silver recovery.

Communities, Inclusion & Social Development

In Brazil, Nexa launched a 24/7 Community Contact Channel across its areas of influence, providing a dedicated platform for inquiries, requests, suggestions and grievances while strengthening stakeholder engagement and grievance management.

The company delivered more than 2,500 medical services to over 900 patients through community health campaigns near its Cerro Lindo and Pasco operations and distributed more than 12,000 school kits to students across more than 60 communities in Peru.

Nexa continued advancing its diversity and inclusion agenda through industry engagement, employee resource groups and leadership initiatives, including participation in Diversibram 2026 and the XVI International Mining Conference.

Governance & Industry Leadership

Nexa strengthened its corporate governance framework through enhancements to advisory committees and governance tools integrated with its Enterprise Risk Management (ERM) framework.

The company was awarded the Gold Seal of the Brazilian GHG Protocol Program for its 2025 greenhouse gas inventory and hosted Zinc College 2026 in Lima, bringing together industry participants to discuss the zinc value chain, market applications and the future of the industry.

At the 17 th Opex Workshop, Nexa received the 28 th Mining and Metallurgical Industry Excellence Award for projects developed by its Aripuanã and Vazante teams, including the Cash Flow Control program focused on operational efficiency and financial predictability.

Financial & Corporate Highlights

At the Annual and Extraordinary General Meetings of Shareholders held on June 25, 2026, shareholders renewed the mandates of all members of the Board of Directors, approved an increase in the authorized share capital and renewed the Board's authorization to increase the issued share capital. Shareholders also approved a share premium reimbursement of US$17.5 million, or US$0.132136 per share, payable on August 11, 2026, to shareholders of record as of July 28, 2026.

In June 2026, S&P Global Ratings reaffirmed Nexa's investment-grade credit rating of 'BBB-' with a 'Stable' outlook.

In July 2026, S&P placed Nexa's 'BBB-' issuer credit rating on CreditWatch with negative implications, following the announcements confirming ongoing discussions between Votorantim S.A. and Boliden AB regarding a potential acquisition of Votorantim's controlling stake in Nexa. S&P indicated that the action reflects the potential change of control rather than Nexa's operating or financial performance and stated its intention to resolve the CreditWatch upon the conclusion of the potential transaction. Nexa's ratings from Fitch Ratings and Moody's remain unchanged.
