Investment Thesis

▲ Bull case

NEXA's structural advantage in silver byproduct exposure is significantly underappreciated by the market, particularly following the Cerro Lindo silver streaming agreement step-down that increased attributable silver production from 35% to 75% of total output effective Q2 2026, translating to approximately 8.25 million additional ounces of silver annually at current production levels; with silver averaging above $120 per ounce during Q1 2026 and structural deficits persisting due to sustained industrial demand from solar PV, EV, and AI infrastructure build-out, this shift alone contributes an incremental $990 million in annual pre-tax cash flow based on quarterly run-rate calculations, yet management did not quantify this impact in forward guidance despite its transformative effect on free cash yield and debt paydown capacity.
The Cerro Pasco integration project's Phase 1 completion in Q4 2026 positions NEXA to unlock multi-decade value through life-of-mine extension beyond 15 years and improved net smelter return (NSR) via sulfide ore processing, yet the market overlooks that the project's true catalyst lies in the concurrent advancement of preparatory studies for Phase 2, including the Picasso shaft assessment, which—despite delayed investment decisions—has already identified higher-grade underground resources with NSR uplift potential exceeding 20% based on recent intercepts like the 16.6-meter 9.6% zinc/3% lead at Massaranduba, signaling that reserve growth is not merely replacing depletion but actively expanding the high-margin resource base ahead of schedule.
NEXA's Aripuana mine is poised for a hidden inflection point in H2 2026 as the fourth tailings filter, commissioned in early May 2026 and expected to be fully operational by Q2 2026, eliminates weather-driven throughput volatility during rainy seasons—a historical drag on Peruvian operations—thereby enabling sustained utilization of its 13,000-tonne quarterly zinc production record (Q1 2026) and unlocking predictable, low-cost output from a mine with one of the longest reserve lives in the portfolio, yet the market remains fixated on sequential Peruvian volatility without recognizing that Aripuana's stability will increasingly offset regional disruptions and drive consistent mining segment EBITDA margins above 50% as grades and plant performance normalize.
The company's disciplined capital allocation—prioritizing debt reduction over aggressive shareholder returns despite surging cash flow—creates a stealthy catalyst: with net leverage already at 1.59x (down from 2.09x YoY) and liquidity of $716 million covering four years of commitments, NEXA is on track to hit its implicit 1.0x leverage target faster than guided, which would unlock significant interest expense savings (currently ~$58 million annually on $929 million LTM EBITDA) and operational flexibility to pursue value-accretive M&A in copper-rich jurisdictions without compromising investment-grade ratings, yet management's avoidance of explicit leverage targets obscures how near-term deleveraging accelerates financial resilience amid commodity cyclicality.
Smelting segment profitability is being underestimated due to the market's narrow focus on low treatment charges (TCs), while NEXA's strategic pivot to byproduct transparency—now reporting sulfuric acid, silver content, and copper cement sales—reveals a hidden margin buffer: in Q1 2026, byproduct credits drove mining segment cash costs to negative $0.76/lb zinc, and similar dynamics are lifting smelting economics despite TC pressure, as evidenced by Cajamarquilla's solid performance and the company's successful spot sulfuric acid sales at premium levels, yet analysts ignore that byproduct revenue now covers over 60% of smelting conversion costs, transforming what appears as a structurally challenged segment into a cash flow contributor poised for expansion as Peruvian mine output normalizes and third-party concentrate demand declines.

▼ Bear case

NEXA's Peruvian operations remain structurally vulnerable to socio-political disruption despite management's confidence in resolving Cerro Lindo rainfall, Atacocha blockades, and El Porvenir shaft constraints, as evidenced by the recurring nature of these issues—illegal community blockades and permitting delays are not isolated events but systemic risks rooted in Peru's volatile social license environment, yet the company provided no concrete metrics on community engagement efficacy or long-term mitigation spending during Q&A, instead relying on historical precedent to dismiss political risk, which ignores how a potential left-leaning presidency could reignite resource nationalism and delay critical environmental approvals for El Porvenir and Atacocha beyond Q1 2027, directly threatening the Cerro Pasco integration timeline and the life-of-mine extension thesis.
The smelting segment's apparent resilience is a mirage driven by temporary byproduct tailwinds, not fundamental strength, as NEXA's own CFO admitted zinc smelting cash costs of $1.40/lb were slightly above the upper end of annual guidance due to low TCs and high LME prices, with management acknowledging that profitability remains under structural pressure from China's concentrate demand, yet they overstate the offsetting power of byproducts like sulfuric acid—whose market tightness is cyclical and subject to global supply surges—without disclosing how much of Q1's $51 million smelting EBITDA was attributable to non-recurring spot acid sales versus sustainable operations, creating a hidden vulnerability where a 10% drop in byproduct prices could erase over half of segment profits amid persistent TC compression.
Exploration upside is being overstated as a near-term catalyst, with NEXA's revised 2026 drilling program of 67,000 meters (up 12%) concentrated at Cerro Pasco and other projects yielding only early-stage intercepts like the Massaranduba result, which—while encouraging—requires years of infill drilling, feasibility studies, and permitting before contributing to reserves, yet management framed exploration as an immediate reserve growth driver despite acknowledging that Phase 2 of Cerro Pasco integration (underground shaft development) hinges on unclear investment timing and that preparatory studies will take the second half of 2026 just to define a plan, meaning no material resource conversion is expected before 2028, creating a gap between optimistic narratives and actual development timelines.
The company's leverage reduction strategy lacks teeth in a downturn scenario, as NEXA's commitment to maintaining net leverage below 1.7x throughout 2026 relies entirely on sustained high metal prices—particularly silver and zinc—yet the CFO conceded they "don't control prices" and expressed uncertainty about achieving even a 1.0x target, revealing that deleveraging is contingent on favorable markets rather than operational discipline, which becomes dangerous if prices reverse: with 7.2-year average debt maturities and 6.27% cost of debt, a return to 2025 EBITDA levels (~$412 million) would spike leverage to 3.6x overnight, breaching covenants and forcing distressed asset sales just as the Cerro Pasco pumping system comes online in Q2 2027.
Aripuana's production record is misleadingly presented as a sustainable run-rate improvement when it was driven by transient grade spikes and plant utilization gains that may not persist, as management attributed the 13,000-tonne zinc output to "higher grades, better plant utilization, and improved operational stability" without disclosing whether the 9.6% zinc/3% lead Massaranduba intercept reflects regional trends or isolated high-grade zones, and given that Aripuana's historical volatility stems from geological complexity and rainfall exposure—even with the new filter—there is no evidence that Q1's performance can be maintained through 2026, especially if Brazilian real appreciation (which increased run-of-mine costs) continues to offset grade benefits, turning a perceived structural advantage into a temporary mirage.
