Monitor upcoming Q2 2026 production results and any further updates on the Cajamarquilla investigation. The ~7kt impact is small relative to annual output and guidance is unchanged, suggesting limited near-term earnings risk. However, any delay in full restart or a material financial finding from the investigation would warrant reassessment.

Executive Summary
Nexa Resources provides an operational update on the gradual resumption of its Cajamarquilla smelter in Peru following a May 13 incident. Electrolysis lines are fully operational, with one casting line back and the others expected by mid-June; the company estimates a ~7kt (~2% of annual production) impact on 2Q26 refined zinc output that it expects to recover in H2 2026. Sales guidance remains unchanged and management states it does not anticipate a material financial impact, making this a routine operational disruption update with limited stock price implications.
