1 Freeport Provides Update on Restart Plans for Grasberg Minerals District PHOENIX, AZ, November 18, 2025 - Freeport (NYSE: FCX) announced today plans to restore large-scale production from PT Freeport Indonesia’s (PTFI) Grasberg operations in Central Papua, Indonesia. As previously reported, PTFI commenced production from the unaffected Deep Mill Level Zone and Big Gossan underground mines in late October 2025. Remediation activities are being advanced to prepare for a phased restart and ramp-up of the Grasberg Block Cave underground mine beginning in second-quarter 2026. Kathleen Quirk, President and Chief Executive Officer, said, “Our team is committed to restoring large-scale, low-cost production at Grasberg in a safe, efficient and responsible manner. We have incorporated the learnings from the recent tragic incident into our future plans and are implementing several initiatives to address the conditions that led to the incident. We will continue to prioritize safety above all else as we restore operations and work to provide benefits to our many stakeholders.” Under the phased restart and ramp-up plans, FCX expects PTFI’s production of copper and gold from the Grasberg minerals district in 2026 to be similar to estimated 2025 volumes, approximating 1.0 billion pounds of copper and 0.9 million ounces of gold. FCX expects PTFI’s production will increase throughout 2026 and 2027 with average annual production of approximately 1.6 billion pounds of copper and 1.3 million ounces of gold for the three-year period 2027-2029. A conference call with securities analysts will be held today at 10:00 a.m. Eastern Time to review the incident, discuss future operating plans and provide an update on FCX’s global business and ongoing initiatives to grow supplies of copper to meet increasing demand for this critical metal.

Important factors that can cause FCX’s actual results to differ materially from those anticipated in the forward-looking statements include, but are not limited to, supply of and demand for, and prices of the commodities FCX produces, primarily copper and gold; changes in export duties and tariff rates; production rates; timing of shipments and sales; price and availability of consumables and components FCX purchases as well as constraints on supply and logistics, and transportation services; changes in cash requirements, financial position, financing or investment plans; changes in general market, economic, geopoli tical, regulatory or industry conditions, including market volatility regarding trade policies and tariff uncertainty; reductions in liquidity and access to capital; PTFI’s ability to successfully complete remediation activities, implement any recommendat ions from the related investigation, safely restart, phase-in ramp-up and achieve full operating rates of production and downstream processing on the expected timeline and optimize production plans; recover amounts under insurance policies; resolve force majeure declarations and maintain relationships with commercial counterparties; changes in tax laws and regulations; political and social risks, including the potential effects of violence in Indonesia, civil unrest in Peru, and relations with local communities and Indigenous Peoples; operational risks inherent in mining, with higher inherent risks in underground mining; mine sequencing; changes in mine plans or operational modifications, delays, deferrals or cancellations, including the ability to smelt and refine or inventory; results of technical, economic or feasibility studies; potential inventory adjustments; potential impairment of long-lived mining assets; satisfaction of requirements in accordance with PTFI’s IUPK to extend mining rights from 2031 through 2041; process relating to the extension of PTFI’s IUPK beyond 2041; cybersecurity risks; any major public health crisis; labor relations, including labor-related work stoppages and increased costs; compliance with applicable environmental, health and safety laws and regulations; weather- and climate-related risks; environmental risks, including availability of secure water supplies; impacts, expenses or results from litigation or investigations; tailings management; FCX’s ability to comply with its responsible production commitments under specific frameworks and any changes to such frameworks and other factors described in more detail under the heading “Risk Factors” in FCX’s Annua l Report on Form 10-K for the year ended December 31, 2024 and in FCX’s Current Report on Form 8-K dated November 18, 2025, each filed with the U.S. Securities and Exchange Commission. The forward-looking statements, including projections, in this presentation are based on current market conditions and several assumptions, and are subject to significant risks and uncertainties. Projections are dependent on operational performance, the timing of restarting and ramping up mining and smelting operations at PTFI following the September 2025 mud rush incident, weather-related conditions and other factors detailed herein. Investors are cautioned that many of the assumptions upon which FCX’s forward-looking statements are based are likely to change after the date the forward-looking statements are made, including for example commodity prices, which FCX cannot control, and production volumes and costs or technological solutions and innovations, some aspects of which FCX may not be able to control. Further, FCX may make changes to its business plans that could affect its results. FCX undertakes no obligation to update any forward-looking statements, which are as of the date made, notwithstanding any changes in its assumptions, changes in business plans, actual experience or other changes. Estimates of mineral reserves and mineral resources are subject to considerable uncertainty. Such estimates are, to a large extent, based on metal prices for the commodities we produce and interpretations of geologic data, which may not necessarily be indicative of future results or quantities ultimately recovered. This presentation also includes forward-looking statements regarding mineral resources not included in proven and probable mineral reserves. A mineral resource, which includes measured, indicated and inferred mineral resources, is a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. Such a deposit cannot qualify as recoverable proven and probable mineral reserves until legal and economic feasibility are confirmed based upon a comprehensive evaluation of development and operating costs, grades, recoveries and other material modifying factors. This presentation also includes forward-looking statements regarding mineral potential, which includes exploration targets and mineral resources but will not qualify as mineral reserves until comprehensive engineering studies establish legal and economic feasibility. Significant additional evaluation is required and no assurance can be given that the potential quantities of metal will be produced. Accordingly, no assurance can be given that estimated mineral resources or mineral potential will become proven and probable mineral reserves. This presentation also contains measures such as unit net cash costs (credits) per pound of copper and molybdenum, and EBITDA (earnings before interest, taxes, depreciation, amortization and accretion), which are not recognized under U.S. generally accepted accounting principles (GAAP). For FCX’s calculation and reconciliation of unit net cash costs (credits) per pound of copper and molybdenum to amounts reported in FCX’s consolidated financial statements refer to “Operations – Unit Net Cash Costs (Credits)” and to “Product Revenues and Production Costs” of FCX’s annual report on Form 10-K for the year ended December 31, 2024, which is available on FCX’s website, fcx.com. For forward-looking non-GAAP measures, FCX is unable to provide a reconciliation to the most comparable GAAP measure without unreasonable effort because estimating such GAAP measures and providing a meaningful reconciliation is extremely difficult and requires a level of precision that is unavailable for these future periods, and the information needed to reconcile these measures is dependent upon future events, many of which are outside of FCX’s control as described above. Forward-looking non-GAAP measures are estimated consistent with the relevant definitions and assumptions. 2
