Freeport-McMoRan's Copper-Tariff Selloff Misses the Real Thesis

Copper hit an all-time high of roughly $14,533 a tonne on the London Metal Exchange on September 8, 2026, and two days later Freeport-McMoRan (FCX) fell 6.6% in a single session. The trigger was not a collapse in demand or a broken mine. It was a Reuters report that the White House had still not decided whether to impose tariffs on refined copper imports, hesitating over affordability concerns. Goldman Sachs called the move overdone and reiterated a Buy on the stock; the broader market was less patient, with copper futures dropping 4.6% and every major miner sold in sympathy.

The first thing to check is whether the tariff headline is even the trade. When Freeport, Southern Copper, Teck, and Alcoa all fell in lockstep — Freeport down 6.6%, Southern Copper down 7.2% — that is a sector-wide policy wash, not a company-specific deterioration. A tariff is a domestic price wedge: it lifts the U.S. Comex premium over the global price by making imported metal costlier. A delay unwinds that premium. But Freeport's earnings are not driven by a Washington ruling; they are driven by the global copper price and its own cost and volume, most of it produced in Indonesia's Grasberg district and Peru, then sold at international prices. The news that moved the sector is a marginal swing factor, not the mechanism that pays Freeport's bills.

That mechanism is worth naming precisely, because it is the honest gauge of the cycle. Freeport's dividend is partly variable and tied to copper prices and free cash flow — in April it declared a $0.15 quarterly payment split between a $0.075 base and a $0.075 variable slip. What that says is that the company pays out more when copper prices and cash generation rise, and it pulls back when they fall. It is a cash-return design that tracks the commodity rather than pretending otherwise. The trailing yield looks thin at about 0.8% not because the dividend is weak but because the stock has run 40% year to date on record copper, so the payout sits on a much larger capital base. For someone evaluating Freeport, the dividend is a thermometer, not the diagnosis.

What actually supports the case is the supply side. Global mine output is falling — roughly 1.1% — just as electrification, grid buildout, and AI data-center construction pull more demand into the wires. Grasberg's expansion has hit delays; Freeport trimmed its 2026 copper sales guidance to about 3.1 billion pounds. That is why copper is at a record in the first place, and it is a structural story that does not depend on whether the Commerce Department lands on 15% or 30%. The tariff conversation has been layered on top of a market already tight for reasons that have nothing to do with trade policy.

The balance sheet also clears the bar the engineer checks before trusting a story. Net debt sits near $5.3 billion against roughly $102 billion in market value, a debt-to-equity ratio around 0.29, and roughly $5.9 billion in trailing operating cash flow against $4 billion of capex. This is not the debt-laden Freeport of a decade ago; the deleveraging is done, which gives it room to fund the Grasberg ramp and return cash while copper is strong.

Now the part Goldman's "attractively valued" glosses over. Freeport trades at roughly 11.9x trailing EV/EBITDA and around 35x trailing earnings — with copper at an all-time high and a year of record pricing already in the stock. That is not a cheap price by history; it is a rich price that is "attractive" only on the assumption that copper stays near record levels, and further attractive if Washington eventually confirms a tariff that keeps the U.S. premium elevated. Reverse that assumption — copper mean-reverts, or the tariff is dropped entirely — and the thin dividend yield provides little cushion against a stock priced for a tight market.

In my view the selloff represents an irrational overreaction to a policy headline that changes nothing about Freeport's supply story or balance sheet. But the honest conclusion cuts the other way too: at 40% year-to-date gains on record copper, the stock has already been paid for the bull case. The tariff is a swing on the margin; the copper price is the thesis, and the variable dividend is the cleanest read on whether that thesis is delivering. Watch the copper price and the quarterly dividend declaration more than the next Washington headline — the first two are business reality, and the third is noise until a ruling actually lands.
