Freeport-McMoRan Shares Fall 6.6% on Tariff Uncertainty

Freeport-McMoRan (FCX) shares declined 6.6% on Thursday to close at $71.21. The S&P 500 index fell 0.6% in the same session. Copper prices dropped amid rising bond yields and reports of White House indecision on tariffs. Market participants feared the proposed tariff would be abandoned to protect manufacturing costs. This uncertainty directly impacted Freeport’s US operations, which management identifies as the primary beneficiary of such a measure.

The selling pressure extended across the entire copper mining sector. Southern Copper (SCCO) shares fell 7.2% during the session. Gold and silver prices also recorded losses. The market treated the drop as a collective mark-down of copper exposure rather than a company-specific issue. Freeport shares remain at approximately double their 52-week low of $34.96. This valuation is supported by the recent rally in copper prices rather than significant revenue growth. Trailing twelve-month revenue stood at $25.87 billion, a marginal 0.2% increase year-over-year.

Tariff Impact On US Pricing

Management stated in July that all US copper sales are priced on the Comex exchange. A potential tariff on copper cathodes could create a price premium in the US market. This would allow Freeport to earn more domestically than its international peers. The proposal under review involves a phased implementation starting in 2027. No final decision has been made by the administration. The lack of clarity has introduced volatility into the stock’s valuation.

The US business segment is becoming a larger contributor to earnings. It was the top earnings driver for the first half of 2026. Mining rates at the Morenci mine ran 30% above the five-year average in the second quarter of 2026. Management projects a 60% increase in US copper production in coming years. This growth is partly driven by a leaching initiative to recover copper from existing stockpiles. A pilot program at Morenci is testing heated leaching solutions to improve recovery rates.

Operational Leverage To Copper Price

Freeport’s financial performance is highly sensitive to copper prices. The CFO’s model estimates that a 10-cent-per-pound change in copper price alters annual EBITDA by roughly $390 million. This calculation uses the average of 2027 and 2028 figures. Management has no control over the commodity price or the tariff decision. These external factors create significant earnings volatility for shareholders.

Volume growth provides a counterbalance to price uncertainty. Production at the Grasberg Block Cave in Indonesia doubled from an April average of 34,000 tons per day to 69,000 tons in June 2026. Freeport is working to restore large-scale production at this site. The CFO expects second-half 2026 copper sales to exceed first-half levels by more than 20%. This operational expansion aims to offset potential price headwinds.

Market Reaction To Policy Risk

Investors are reassessing the risk profile of copper miners. The uncertainty over US trade policy has dampened sentiment. GN markets/commodities notes that the sector is reacting to macroeconomic signals. Rising yields and trade protectionism concerns are key drivers. The market is pricing in the potential for higher input costs for manufacturers. This could reduce demand for copper in the long term.

Freeport’s stock movement reflects a broader thematic shift. The company is viewed as a proxy for copper demand and US policy. The 6.6% drop underscores the sensitivity of the stock to these factors. Traders are taking positions based on macroeconomic data rather than individual company performance. The lack of clarity on tariffs remains the central issue. Resolution of this policy question will likely determine the next direction for the stock.
