Freeport Announces Plans to

Boost U.S. Copper & Molybdenum Production  Significant expansion and modernization program approved for Bagdad, Arizona  Bagdad to become the second-largest U.S. copper producer and a top U.S. molybdenum producer

 Bagdad’s long-term cost position expected to benefit from modern technology, automation and economies of scale

PHOENIX, AZ, November 4, 2026 – Freeport (NYSE:FCX) announced today that its Board of Directors approved a $4.5 billion expansion and modernization program for its wholly owned Bagdad copper and molybdenum operation in northwest Arizona. The brownfield project is designed to maximize the full potential of the resource and is expected to more than double Bagdad’s mining and milling rates. This investment would increase annual long-term copper production to over 400 million pounds of copper per annum (incremental production of approximately 225 million pounds per annum) and molybdenum production to over 20 million pounds per annum (incremental production of 12 million pounds per annum). Freeport plans to deploy modern technologies, automation and leverage existing operations to improve Bagdad’s long-term cost position and performance. The expansion would position Bagdad as the second-largest copper mine in the United States (U.S.), behind FCX’s Morenci operation, as well as a leading U.S. molybdenum producer and one of the lowest-cost operations in FCX’s U.S. portfolio. Kathleen Quirk, President and Chief Executive Officer, said: “Freeport’s significant resource base provides an attractive portfolio of value-enhancing, organic growth options as we work to meet growing demand for our products. We are pleased to proceed with the Bagdad expansion, an important step in advancing Freeport’s U.S. copper growth strategy. This low-risk brownfield project builds on Bagdad’s substantial reserve base, long operating history, existing infrastructure and experienced workforce to deliver new U.S. copper and molybdenum production and further strengthen Freeport’s position as America’s Copper Champion®.” The Bagdad mine has operated since 1945 and has a current reserve life exceeding 80 years before considering additional mineral resources. In 2025, Bagdad completed its fleet conversion, becoming the first major U.S. mine with a fully autonomous haulage fleet. The expansion will leverage Bagdad’s established operating history and extensive knowledge of the ore body while incorporating modern technology to strengthen Bagdad’s production profile. FCX is advancing engineering, procurement planning and early works to support efficient project execution. Planned capital expenditures will be incorporated into FCX’s updated capital expenditure outlook and classified as discretionary under FCX’s financial policy. Current estimates indicate that approximately 20% of project costs are expected to be funded in 2027, 30-35% in 2028 and the balance in 2029-2030.

{N4163160.1} 2 Capital cost estimates are based on current market conditions. Ongoing inflationary pressures and cost escalation could affect these estimates. Freeport aims to complete the project within current cost estimates and timelines. PROJECT HIGHLIGHTS  Expanded processing capacity to support a large mineral reserve base (2.6 billion metric tons of ore with copper equivalent grade of 0.43%)  New concentrator facilities expected to provide approximately 115,000 tons per day of incremental nameplate processing capacity with potential to increase over time  Supporting infrastructure, including a new primary crusher, overland conveyor, water pipeline, power line, mining equipment and related facilities  Modern technology, including a fully autonomous truck fleet to support efficient increases in mining rates  Expected annual long-term production of over 400 million pounds of copper (approximately 225 million pounds of incremental production) and over 20 million pounds of molybdenum per annum (approximately 12 million pounds of incremental molybdenum production) o Equivalent to incremental growth of approximately 130 thousand tons of copper equivalent per annum based on life of mine  Future incremental capital costs for a new concentrator, mining equipment and expanded infrastructure are expected to approximate $4.5 billion  Construction period of approximately 3.5 years, with initial production targeted in mid-2030  Approximate 20% reduction in long-term unit net cash costs, with anticipated benefits from economies of scale, technology and molybdenum by-product credits  Project break-even economics supported at a copper price of approximately $4.00 per pound ($20 per pound molybdenum) with substantial upside to expected favorable long-term markets  Significant economic benefits for Arizona, including more than 4,000 direct and indirect jobs during construction and thousands of long-term employment opportunities FREEPORT: Foremost in Copper
