Read MoreHide Full Article

Key Takeaways

  • FCX's unit net cash costs jumped 74% as lower copper volumes pressured second-quarter results.
  • FCX expects third-quarter unit costs of $2 per pound, up about 43% year over year.
  • Copper sales fell 30% in Q2 as Grasberg's phased ramp-up kept operating rates under pressure.

Freeport-McMoRan Inc. (FCX - Free Report) saw its earnings jump in the second quarter on significantly higher realized metal prices, but remains exposed to cost pressures. Its second-quarter unit net cash costs climbed 74% year over year to $1.97 per pound due to lower copper volumes.  

Freeport expects unit net cash costs of $2 per pound for the third quarter, while projecting a full-year average of roughly $1.9 (compared with $1.65 in 2025). The projected third-quarter unit cost reflects a roughly 43% year-over-year increase. 

The uptick in costs reflects higher costs of energy and other consumables due to the Middle East conflict and persistent pressure on volumes. Higher costs are expected to weigh on the company's margins.   

FCX’s copper sales volumes tumbled approximately 30% year over year in the second quarter to 710 million pounds. The downside primarily resulted from lower operating rates during the phased ramp-up of the Grasberg Block Cave mine in Indonesia, following the mud rush incident in September 2025.  The company’s third-quarter outlook for copper sales volumes of 750 million pounds indicates a sequential improvement but a 23% year-over-year decline.

Among FCX’s peers, Southern Copper Corporation (SCCO - Free Report) reported lower unit costs in the second quarter. Southern Copper’s operating cash cost per pound of copper, net of by-product revenue credits, fell by roughly 17% from the prior-year quarter. SCCO attributed the decline to higher by-product revenue credits.

BHP Group Limited’s (BHP - Free Report) Escondida operation reported a 10% year-over-year decline in unit costs to $1.07 per pound in fiscal 2026. Unit costs at BHP’s Spence operation rose 4% to $2.15 per pound. BHP also reported Copper South Australia’s unit cost of $0.32 per pound, down 73% year over year.
