Freeport declares force majeure at Grasberg, expects lower copper, gold sales

Freeport-McMoRan declared force majeure at its Grasberg mine in Indonesia, leading to a 10.4% share price drop and revised Q3 consolidated sales forecasts down by approximately 4% for copper and 6% for gold. The company anticipates a phased restart of the major copper and gold mine only by H1 2026, with 2026 Indonesian production potentially 35% below previous estimates. This significant disruption immediately drove London Metal Exchange copper prices up over 3% to a 15-month high, signaling a tighter global copper market, which analysts note could benefit Freeport's Americas operations despite the severe setback at Grasberg.

Analysis

Freeport-McMoRan (FCX) has declared force majeure at its Grasberg mine in Indonesia, triggering a significant 10.4% decline in its share price. The operational halt, caused by a material flow blockage that resulted in two fatalities, has led the company to revise its third-quarter consolidated sales guidance downward by approximately 4% for copper and 6% for gold. The long-term implications are severe, with a phased restart of the mine not anticipated until the first half of 2026 and a potential 35% reduction in 2026 production from its Indonesian unit compared to previous estimates. This disruption, which Jefferies analysts described as more significant than anticipated, immediately tightened the global copper market, pushing London Metal Exchange copper prices up by over 3% to a 15-month high. While the Grasberg situation presents a major setback, the resulting higher copper prices are expected to positively impact Freeport's operations in the Americas, creating a countervailing financial effect for the company's diversified portfolio.

Key Decisions for Investors

• Investors should re-evaluate near-term exposure to Freeport-McMoRan, as the significant downward revision to Q3 sales and the extended multi-year timeline for the Grasberg restart introduce substantial earnings uncertainty.
• Monitor the impact of higher global copper prices on the profitability of Freeport's Americas-based operations, as this may provide a partial offset to the production losses and financial impact from the Grasberg disruption.
• Long-term investors must factor in the heightened operational risk profile demonstrated by this incident and the projected 35% reduction in 2026 Indonesian output when assessing the company's future valuation and growth trajectory.
