FCX · Q1 2026 Earnings

Narrative arc: Tariff-driven margin reframing → Defensive humility on cave-mining complexity → Offense-oriented growth and de-risked restart → Bottlenecks, delays, and cost loss of control.

The Grasberg restart narrative has fully reversed in two quarters. Q4 FY2025 management said "the progress to date continues to de-risk the plan," with mudwork 97% complete and PB2/PB3 startup locked for first-half Q2 FY2026. This quarter, the same operation is characterized as "still very early in our initial ramp up, and a number of factors could affect rates positively or negatively as we go through the coming months." Production from PB2/PB3 is now capped at 60,000 tpd in H2 versus the prior 100,000 tpd target, with the 90,000 tpd range pushed to mid-2027. Overall PTFI capacity, previously forecast at 85% in H2 FY2026 and 100% by end-2027, is now guided to 65% in H2 FY2026, 80% by mid-2027, and approaching full capacity by end-2027. The shift from "de-risked" to "very early" inside a single quarter on the operation that anchors the FY2026 recovery thesis is the single most consequential tone change in the print.

The wet-ore framing also collapsed. Q3 introduced the mud rush as "unprecedented"; Q4 framed cave management as solvable through phased panel restarts and protective barriers; this quarter exposes that pre-incident draw-point models predicted a 2:1 dry-to-wet ratio that actual conditions have not delivered. "Currently, there are 10 panels out of a total of 23, compared to only one in September, which do not meet the one-to-one dry to wet ratio criteria." The September baseline was a single panel out of spec; now it's nearly half the system. This is not a refinement of the Q4 plan — it's evidence the Q4 plan was built on optimistic moisture assumptions, and material-handling chute modifications can only proceed at vendor speed.

Cost control has visibly slipped from operating lever to external shock absorber. Q4 framed the FY2026 $1.75/lb unit cost guide as a cost-down thesis anchored in leach scaling and PTFI normalization; this quarter, "the sharp rise in diesel prices in March equates to an approximate $500 million cost increase on an annualised basis." That single line moved the FY guide $0.20/lb higher. The leach-scaling cost bridge to $2.50/lb is now explicitly under review per Q&A — management was disciplined enough to admit "unit cost path to $2.50 intact on controllables but under review given diesel volatility." The narrative has shifted from "we control our cost path" to "controllables are intact but uncontrollables matter more."

The demand thesis remains intact but is doing more rhetorical work to offset the operational disappointment. "We are now in a new era of growth about copper, which is broad-based and driven by the growing demand for electricity. Simply, electricity equals copper." This is the structural anchor that lets management hold a bullish long-term frame while every near-term operational metric deteriorates. The tone disconnect — long-term confidence at maximum, near-term execution at minimum — is the kind of split that warrants watching for further FY guide cuts if Grasberg slips again.

Finally, on the leach program, the framing held. Management still guides to 300–400M lbs/annum in FY2026–2027 with 800M lbs by 2030, and the Goldman Q&A revealed second-generation additives showing "multiplier benefits in lab" and heat pilots starting at Morenci. This is the one growth lever that has not been downgraded across three quarters of bad news, and it's now load-bearing for the entire U.S. cost-down thesis.
