Silver Stream Step-Down Fires a ~$100M-a-Year Cash Unlock at Nexa

Silver Stream Step-Down Fires a ~$100M-a-Year Cash Unlock

Nexa Resources' first-quarter 2026 report reads as a genuine inflection. Adjusted EBITDA more than doubled year over year to $283 million at a near-32% margin, net income reached $118 million, and — most importantly — the company converted two long-telegraphed catalysts into live economics: the Cerro Lindo silver stream step-down and the fourth tailings filter at Aripuana. The deleveraging story, already on track, now has a fresh accelerant.

The silver unlock: from 65% to 25%

The single most consequential change is mechanical and effectively permanent. In April, Nexa crossed the delivered threshold on its Cerro Lindo silver streaming agreement, dropping the stream share from 65% to 25%.

in April, we reached a delivered threshold under our Cerro Lindo silver streaming agreement. As a result, the stream share of Cerro Lindo's production stepped down from 65% to 25%, with the remaining 75% now to be sold at prevailing market prices.

This is precisely the event management flagged on the February call, when José Carlos noted the step-down would arrive “in probably in May of this year.” — José Carlos del Valle, CFO · 2026-02-27 The April delivery makes it effective — and the arithmetic is now explicit. With Cerro Lindo producing roughly 3.6 million ounces of silver a year, the extra 40 percentage points of production it no longer has to deliver equate to “about $100 million more per year of cash generation.” — Ignacio Rosado, CFO · 2026-05-07 That lands in a tape where silver averaged 164% above the year-ago quarter and briefly traded above $120 per ounce. Nexa produces around 11 million ounces of silver annually, and the silver stream step-down lets it keep full market upside on its flagship mine instead of selling at a fixed price. Nexa is not alone — the global tape history shows precious-metal names among the top 90- and 30-day advancers on silver and "high metal prices" themes — but its edge is idiosyncratic: it is structurally retaining a far larger share of the metal it already mines.

The leverage onto silver shows up directly in unit costs: cash cost net of byproducts came in at negative $0.76 per pound, far below guidance, driven by stronger byproduct credits across silver, copper, and gold — a clean demonstration of the operating leverage the company promised, with the mining segment printing a 50% EBITDA margin.

From bottleneck to full runtime: Aripuana and Cerro Pasco

The second catalyst is Aripuana. The fourth tailings filter — the equipment that finally eliminates the rainy-season bottleneck that has haunted the project for years — completed construction in late April, with commissioning underway in early May and full capacity targeted for the second half of 2026. Q1 delivered a record 13,000 tonnes of zinc at the asset, which management now calls one of the central pillars of long-term cash flow generation. Alongside it, the Cerro Pasco integration stays on schedule — Phase 1 finalizes in the fourth quarter of 2026 with tailings pumping to begin in the second quarter of 2027, extending life of mine at the complex beyond 15 years. Exploration was raised ~12% to nearly 67,000 meters, concentrated at Cerro Pasco — a direct bet on the resource endowment that will justify Phase 2, a decision management says is coming in the second half of this year.

Deleveraging accelerates; the smelting counterpoint

The balance sheet keeps delivering. Net leverage fell to 1.59x from 2.09x a year ago, average cost of debt improved to 6.27% from 6.49%, and the freed silver cash is earmarked for gross-debt reduction. José Carlos reaffirmed the goal: “reaching an overall net leverage of 1x would give us a lot of comfort.” — José del Valle Castro · 2026-05-07 The ~$100-million-per-year silver uplift is what makes that timeframe now look like a function of prices rather than operational risk.

The counterpoint is smelting. Zinc smelting EBITDA margin was just 8% ($51 million), and management is blunt about the structural drag:

all of our smelters are facing a profitability problems in terms of the TCs.

The partial offset is byproducts — a tight sulfuric acid market and higher silver and copper credits. Tellingly, the company expanded its earnings release this quarter to break out byproduct sales (sulfuric acid, silver content, copper cement) — a transparency move that signals management wants the market to see how much of smelting economics now hinge on sulfuric acid and other non-zinc outputs against persistently low TCs.

A buyer in the making — and the political overlay

Behind the numbers sits a strategic question. Pressed on reports that its parent may be weighing a divestiture with European buyers circling, the CEO declined to comment but was emphatic about intent: “we are very active on looking for opportunities to grow Nexa... especially in copper.” — Ignacio Rosado, CFO · 2026-05-07 Between the deleveraging goal and the new cash generation, Nexa is positioning itself as a consolidator — with accretive opportunities in mining-friendly jurisdictions — not a seller. Finally, the Peruvian election overlay is the recurring risk note, and management's answer echoes prior calls (“the income that they get from the mining sector is so important that they cannot affect the mining companies” — Ignacio Rosado, Chief Operating Officer · 2025-10-31). The closing caveat — “we have to be prepared to any scenario” — Ignacio Rosado, CFO · 2026-05-07 — is best read alongside the bigger message: the binding constraints on Nexa are now operational, and those just got structurally smaller.
