Analysis · SID · Manufacturing
CSN's mining subsidiary is temporarily cutting lower-grade iron ore production at the Pires Complex, citing weaker market conditions and higher freight costs. The company cut its 2026 production and third-party ore purchase guidance from 45.0–47.0 Mt to 39.0–41.0 Mt — a reduction of roughly 13% at the midpoint — and raised its C1 cash cost guidance from US$22.0–23.5/ton to US$25.0–26.0/ton. Lower volumes plus higher unit costs compress margins on both sides, directly pressuring earnings and free cash flow at a time when the company is already managing elevated leverage and an NYSE non-compliance notice for its ADSs trading below $1.00.
