Ero Copper Corp. (ERO) Income Statement

The series shows growth that is lumpy rather than steady, with 2025Q4 and 2026Q3 both printing outsized prints against intervening quarters. This pattern suggests the trajectory may be driven by pricing timing and shipment cadence at the MCSA complex as much as by underlying throughput. Investors should monitor whether the 2026Q3 run-rate persists into subsequent quarters before extrapolating it into forward earnings.

The margin expansion is substantial, but the quarter-to-quarter variance from 39.8% to 50.9% indicates sensitivity to feed grade and concentrate pricing rather than a stable structural shift. Because a large share of costs is fixed, incremental volume appears to lift margins, which may indicate operating leverage that reverses quickly if grade or copper prices weaken. Analysts should treat the current peak margin as a cyclical high until grade consistency is demonstrated.

Operating income of $145.3M compares with gross profit of $169.6M, implying roughly 86% of gross profit converts to operating income after modest SG&A. This conversion appears favorable, though SG&A itself fluctuated between $5.7M and $24.3M across the window, which warrants further investigation into whether the reported figures reflect timing effects. The operating leverage looks real but is not yet proven across a full cycle.
