Nexa Resources S.A. (NEXA) Income Statement

The move from roughly $627M to above $900M over six quarters reflects a combination of recovering metal prices and volume contribution from the Aripuanã ramp-up, though the reported figures do not isolate how much came from each driver. The sharp swings between quarters, including a 7.6% gain in 2026Q2 followed by a 6.7% revenue decline in 2026Q3 on a net basis, suggest the top line remains highly sensitive to commodity and treatment charge timing. Investors should treat the 8.2% trailing growth rate as a cyclical recovery signal rather than evidence of durable expansion until volumes and pricing can be separated in the disclosures.

The swing of roughly fifteen points in gross margin within a single year points to a business whose profitability is governed largely by external factors such as zinc prices, treatment charges, and energy costs rather than by structural pricing power. The retreat from the 2026Q1 peak suggests part of the recent improvement may have been cyclical rather than permanent. Investors would need evidence that consumables and energy inflation are being offset before concluding the current margin band is sustainable.

Overhead appears well controlled, with SG&A remaining in a narrow range even as revenue moved substantially, which supports the view that incremental gross profit drops efficiently to operating income. However, the operating income decline in 2026Q3 relative to gross profit growth in prior quarters indicates that depreciation and other unreported operating costs may be absorbing a growing share of the gross profit base. This warrants further investigation into the cost lines beneath gross profit.
