• Third-quarter 2026 consolidated copper and gold production approximated expectations
• Third-quarter 2026 consolidated copper sales expected to approximate July estimates; consolidated gold sales impacted by timing in Indonesia
• Mining operations in the Grasberg minerals district proceeding in line with expectations
• Operations at PTFI’s smelter re-commenced in late August 2026
• Positioned for future growth

Freeport (NYSE: FCX) today provided an update on its third-quarter 2026 operating results.

CONSOLIDATED RESULTS

Third-quarter 2026 consolidated copper production of approximately 830 million pounds was in line with expectations, with slightly better results from international operations offsetting slightly lower production in the U.S.

Third-quarter 2026 consolidated gold production of approximately 230 thousand ounces approximated expectations. Changes in the timing of gold sales at PT Freeport Indonesia (PTFI) resulted in the deferral of approximately 60 thousand ounces of refined gold from third-quarter 2026 to fourth-quarter 2026.

FCX expects its consolidated copper sales for third-quarter 2026 to approximate its July 2026 estimate of 750 million pounds. FCX expects consolidated gold sales for third-quarter 2026 to approximate 100 thousand ounces, which is below its July 2026 estimate reflecting the impact of deferred gold sales.

Consolidated unit net cash costs (net of by-product credits and excluding idle facility and restoration costs associated with the phased ramp-up of the Grasberg Block Cave underground mine) for third-quarter 2026 are currently expected to be approximately 5% above the July 2026 estimate of $2.00 per pound of copper, principally reflecting lower by-product credits resulting from the impact of deferred gold sales.

FCX estimates its third-quarter 2026 consolidated average realized price to exceed $6.50 per pound of copper.

The U.S. operations experienced lower than planned operating rates in third-quarter 2026 associated with an increased frequency of localized flooding, power outages and strong winds. In Indonesia, abnormally dry weather conditions have been generally favorable for mining but present various challenges in the milling process which are being actively managed with limited impact to date.

GRASBERG UPDATE

Significant progress continued for the phased ramp-up of the Grasberg Block Cave underground mine. During third-quarter 2026, mill throughput averaged approximately 140,000 metric tons of ore per day (approximating 67% of normalized rates prior to the September 2025 incident), including approximately 70,000 metric tons of ore per day from the Grasberg Block Cave. Upgrades to the material handling system at the Grasberg Block Cave haulage level are progressing toward completion by early 2027, and preparations continue for the targeted restart of production from Production Block 1S by mid-2027. FCX continues to expect to reach 80% of capacity in mid-2027 and approach full capacity by year-end 2027.

PTFI’s smelter in Eastern Java, which was temporarily suspended following the September 2025 Grasberg incident, successfully re-commenced operations in late August 2026. Ramp-up activities are proceeding in line with expectations. A recent video highlighting the operation is available on fcx.com. PTFI has combined smelting capacity, including PT Smelting, to produce up to approximately 800,000 metric tons of cathode per annum and a precious metals refinery capable of processing all of PTFI’s gold production.

FUTURE GROWTH

FCX is strongly positioned for future growth opportunities with ongoing progress on the Grasberg recovery, innovation-led growth and potential organic brownfield development opportunities. During third-quarter 2026, FCX continued to progress its America’s Copper Champion^TM growth plans, including advancing projects to scale its innovative leach initiative and finalizing work to reach an investment decision by year-end 2026 to double the capacity of its Bagdad operation in Northwest Arizona. In addition, FCX continues to advance the regulatory process for a potential transformative expansion of its El Abra mine in Chile.

FCX plans to release its third-quarter 2026 earnings results before the market opens on Tuesday, October 27, 2026, and will hold a conference call to discuss the results at 10:00 a.m. Eastern Time.
