We recognize that as the climate changes, our operations, workforce, communities, biodiversity and ecosystems, supply chains and customers may be exposed to changes in the frequency, intensity and/or duration of intense storms, drought, flooding (including from sea level rise at our coastal operations), wildfire, wildfire and other extreme weather events and patterns (such as extreme heat). For example, The physical impacts associated with changing climate conditions could amplify existing operational and environmental risks at our operating sites, such as water availability, tailings management, flooding and stormwater management, and infrastructure disruptions. Periodically, we have experienced severe flooding, disruptions to our remote mining operations in Indonesia as a result of flooding and debris flow from heavy rain and landslides in early 2023 at our remote mining operations in Indonesia, which temporarily halted mining and processing work and damaged infrastructure near the milling complex. Such potential physical impacts of climate change on our operations are highly uncertain and would vary by operation based on particular geographic circumstances. For example, at many of our mine sites, climate change is projected to impact local precipitation regimes, resulting in shorter-duration, higher-intensity storm events, and the potential for less precipitation overall. We could face increased operational costs associated with managing additional volumes of storm water during more intense future events, including supply disruption, delays, damage to or inaccessibility of our facilities and increased pricing of consumables and components we purchase. In addition, the potential for overall decreases in precipitation could affect the availability of water needed for our operations, leading to increased operating costs, or in extreme cases, disruptions to our mining operations. For additional information regarding risks relating to availability of water and operational risks inherent in mining, see related risk factors above. landslides.

Environmental Obligations. Environmental expenditures are charged to expense or capitalized, depending upon their future economic benefits. Accruals for such expenditures are recorded when it is probable that obligations have been incurred and the costs can be reasonably estimated. Environmental obligations attributed to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) or analogous state programs are considered probable when a claim is asserted, or is probable of assertion, and FCX, or any of its subsidiaries, have been associated with the site. Other environmental remediation obligations are considered probable based on specific facts and circumstances. FCX’s estimates of these costs are based on an evaluation of various factors, including currently available facts, existing technology, presently enacted laws and regulations, remediation experience, whether or not FCX is a potentially responsible party (PRP) and the ability of other PRPs to pay their allocated portions. With the exception of those obligations assumed in the acquisition of FMC that were initially recorded at estimated fair values (refer to Note 10 for further discussion), environmental obligations are recorded on an undiscounted basis. Where the available information is sufficient to estimate the amount of the obligation, that estimate has been used. Where the information is only sufficient to establish a range of probable liability and no point within the range is more likely than any other, the lower end of the range has been used. Possible recoveries of some of these costs from other parties are not recognized in the consolidated financial statements until they become probable. Legal costs associated with environmental remediation (such as fees to third-party legal firms for work relating to determining the extent and type of remedial actions and the allocation of costs among PRPs) are included as part of the estimated obligation.

We have a potential expansion project defined an opportunity to more than double the concentrator capacity of the Bagdad operation in northwest Arizona. Bagdad’s reserve life currently exceeds 80 years and supports an expanded operation. In late 2023, we We completed technical and economic studies, which studies in late 2023 and are updating these studies in advance of a potential investment decision during 2026. These studies indicate the opportunity to construct new concentrating facilities to increase copper production by 200 to 250 million pounds per year at estimated year. Estimated incremental project capital costs of approximately costs, which continue to be reviewed, approximate $3.5 billion. Expanded operations would provide improved efficiency and reduce unit net cash costs through economies of scale. Project economics indicate that the expansion would require an incentive copper price in the range of $3.50 to $4.00 per pound and approximately three to four years to complete. The decision of whether to proceed and timing of the potential expansion will take into account overall copper market conditions, availability of labor and other factors, including deployment of our autonomous haul truck fleet conversion expected by year-end 2025 and expanding housing alternatives to support long-range plans. In parallel, we are enhancing local infrastructure and advancing activities for expanded tailings infrastructure projects required under long-range plans in order to advance the potential construction timeline.

In 2005, at the direction of the Maricopa County Superior Court directed Court, the Arizona Department of Water Resources (ADWR) to prepare (ADWR), prepared detailed recommendations regarding the delineation of the “subflow” zone of the San Pedro River, a tributary of the Gila River. Subsurface water within the subflow zone is presumed to constitute appropriable subflow rather than groundwater. Although we have minimal interests in the San Pedro River Basin, a decision that re-characterizes groundwater in that basin as appropriable subflow may set a precedent for other river systems in Arizona that could have material implications for many commercial, industrial, municipal and agricultural users of groundwater, including our Arizona operations. In 2017, the court approved ADWR’s proposed subflow zone maps; water pumped from wells located inside the mapped subflow zone is now presumed to be appropriable subflow. No party has appealed that decision. Although our interests in the San Pedro River Basin are limited, the decision to re-characterize groundwater in that basin as appropriable subflow could set a precedent for other river systems in Arizona. Such a precedent could have significant implications for many commercial, industrial, municipal and agricultural users of groundwater, including for our Arizona operations.
