Prior to the expiration of its export license on September 16, 2025, the gold produced by PTFI was primarily sold as a component of its copper concentrate or in anode slimes, which are a product of the smelting and refining process. Gold was generally priced at the average London PM gold price for a specified month near the month of shipment. Revenues from gold sold as a component of PTFI’s copper concentrate were recorded net of treatment charges, royalties, export duties and allowances for unrecoverable metals, and revenues from gold sold in anode slimes were recorded net of royalties and refining charges. With the completion of its downstream processing facilities during 2025, PTFI sells gold bars produced by the PMR primarily priced at the London PM gold price near the date of shipment, net of royalties."

      "current_body": "Our operations are subject to extensive and complex environmental laws and regulations governing the generation, storage, treatment, transportation and disposal of hazardous substances; solid waste disposal; air emissions; wastewater discharges; remediation, restoration and reclamation of environmental contamination, including mine closures and reclamation; protection of endangered and threatened species and designation of critical habitats; and other related matters. In addition, we must obtain regulatory permits and approvals to start, continue and expand operations. As a mining company, compliance with environmental, health and safety laws and regulations is an integral and costly part of our business. We conduct our operations in a manner that aims to protect public health and the environment. We believe our operations follow applicable laws and regulations in all material respects, and we have internal company policies that in some instances go beyond compliance with such laws and regulations. At December 31, 2025, we had $2.0 billion recorded in our consolidated balance sheet for environmental obligations and $3.8 billion recorded for asset retirement obligations. We incurred environmental capital expenditures and other environmental costs (including our joint venture partners’ shares) to comply with applicable environmental laws and regulations that affect our operations totaling $0.5 billion in 2025, $0.6 billion in 2024 and $0.5 billion in 2023, and we expect to incur approximately $0.7 billion in 2026. The timing and amounts of estimated payments could change 6 6 6 6 6 6 Table of Contents Table of Contents Table of Contents as a result of changes in regulatory requirements, changes in scope and costs of reclamation activities, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters. For information about environmental laws and regulations at our global operations, including legal proceedings and related costs, and reclamation matters, see below as well as Item 1A. “Risk Factors,” Item 3 “Legal Proceedings” and Notes 1, 10 and 11. United States. There are a number of federal and state environmental laws and regulations that apply to our properties and may affect our operations. Laws such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA) and similar state laws may expose us to joint and several liability for environmental damages caused by our operations, or by previous owners or operators of properties we acquired or are currently operating or at sites where we previously sent materials for processing, recycling or disposal. Other federal and comparable state environmental laws have affected, or could in the future affect, us including, but not limited to, the Resource Conservation and Recovery Act, the Clean Air Act and the National Environmental Policy Act. We have substantial obligations for environmental remediation on mining properties previously owned or operated by FMC and certain of its affiliates. Our operations are subject to state regulations governing mine closures and reclamation. Closure plans are required to be updated every six years in Arizona and every five years in New Mexico and Colorado. We are also required by U.S. federal and state laws and regulations to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans for our mining properties if we are unable to do so. Most of our financial assurance obligations are imposed by state laws that vary significantly by jurisdiction, depending on how each state regulates land use and groundwater quality. The U.S. Environmental Protection Agency (EPA) and state agencies may also require financial assurance for investigation and remediation actions that are required under settlements of enforcement actions under CERCLA or similar state laws. Regulations have been, and may in the future be, considered at various governmental levels to increase financial responsibility requirements both for mine closure and reclamation. Our U.S. mining operations are also subject to regulations under the Endangered Species Act (ESA) that are intended to protect species listed by the U.S. Department of the Interior’s Fish & Wildlife Service (FWS) as endangered or threatened, along with critical habitat designated by FWS for these listed species. The ESA may affect the ability of landowners, including us, to obtain federal permits or authorizations needed for expansion of our operations, and may also affect our ability to obtain, retain or deliver water to some operations. New or revised environmental regulatory requirements are frequently proposed, many of which may result in substantially increased costs for our business, including those discussed above and in Item 1A. “Risk Factors.” For example, in 2024, EPA amended its rule establishing standards for hazardous air pollutant emissions from primary copper smelters (Copper Smelter Rule). This final rule would impact our Miami, Arizona smelter operations, which process a significant portion of the copper concentrate produced by our U.S. copper mines. However, in March 2025, EPA announced that it will reconsider, among others, the Copper Smelter Rule, and in October 2025, a presidential proclamation exempted the Miami smelter from the compliance deadlines in the Copper Smelter Rule for two years. EPA’s reconsideration of the Copper Smelter Rule continues and upon its proposal, we will evaluate processes and equipment modifications and the costs involved, which could be significant. Our appeal of EPA’s Copper Smelter Rule to the Court of Appeals for the District of Columbia Circuit remains suspended pending resolution of several petitions for reconsideration to EPA filed by us and other parties. EPA and state agencies continue to consider regulations for man-made organic compounds that could be present in soil, groundwater and surface water at our existing and former operations. These regulations may include drinking water standards, hazardous waste requirements, and hazardous substance designations for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA). For example, in September 2025, EPA announced that it intends to retain the hazardous substance designation for PFOS and PFOA and will initiate future rulemaking to establish a uniform framework governing designation of hazardous substances under CERCLA. In addition, in January 2025, EPA published its final toxicological assessment for inorganic arsenic, which may be used by federal and state regulators to revise regulatory standards under various environmental programs, including water quality standards and cleanup levels at remediation sites, and in October 2025, EPA announced updated guidance and processes concerning the cleanup of lead in residential soils. We are working with federal and state agencies to understand possible ramifications to our projects from these developments and will monitor any additional regulatory guidance, rulemaking and other regulatory activities. 7 7 7 7 7 7 Table of Contents Table of Contents Table of Contents In November 2025, EPA and the U.S. Army Corps of Engineers proposed to revise the final rule amending the revised definition of the “waters of the United States” issued in 2023. Subject to future court decisions (including additional successful legal challenges) and additional administrative rulemaking and related guidance, which may further affect the scope of the final rule, we may need federal authorization under the Clean Water Act (CWA) to expand some of our operations. Further, even where federal authorization is not otherwise required, some states have adopted or are developing programs to require permits for discharges to waters that are no longer subject to the CWA including discharges of dredged or fill material. Peru. The General Environmental Law (Law No. 28611) establishes the main environmental guidelines and principles applicable in Peru. Pursuant to the General Environmental Law, the Ministry of Energy and Mines (MINEM) issued national environmental regulations, which have gradually replaced prior guidelines governing governmental agencies’ environmental competencies. The Environmental Evaluation and Oversight Agency has the authority to inspect mining operations and fine companies that fail to comply with prescribed environmental regulations and their approved environmental assessments. Cerro Verde is subject to regulation under the Mine Closure Law administered by MINEM. Under the closure regulations, mines must submit a closure plan every five years that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and post-closure plans, and financial assurance. In compliance with the requirement for five-year updates, Cerro Verde submitted its updated closure plan and cost estimates and received approval from MINEM in December 2023. The Cerro Verde mine has developed and continues to implement detailed, comprehensive mine waste and tailings management programs to meet the applicable Peru waste regulations and our internal environmental management practices. These programs incorporate commitments included in the Environmental and Social Impact Studies and the engineer of record designs for the specific cases of tailings storage facilities and certain leach pad stockpiles. For any future projects, including at existing facilities, Cerro Verde also may be required by MINEM or the National Environmental Certification Service for Sustainable Investments to incur additional costs to comply with the requirements of new regulations that provide for the adequacy of the transportation and final disposal of tailings. Chile. El Abra is subject to regulation under the Mine Closure Law administered by the Chile Mining and Geology Agency. In compliance with the requirement for five-year updates, El Abra submitted an updated plan with closure cost estimates in August 2025. The El Abra mine has developed and continues to implement detailed, comprehensive mine waste programs to meet the applicable Chilean waste regulations and our internal environmental management practices. These programs incorporate commitments included in the Environmental and Social Impact Studies, and the engineer of record designs for the specific cases of certain leach pad stockpiles. Indonesia. PTFI holds multiple permits from national, provincial, and regency regulatory agencies, including groundwater use permits, effluent and air discharge permits, solid and hazardous waste storage and management permits and protection of forest borrow-to-use permits. Where permits have specific terms, renewal applications are made to the relevant regulatory authority as required, prior to the end of the permit term. In December 2018, Indonesia’s former Ministry of Environment and Forestry (MOEF) issued a revised environmental permit to PTFI to address certain operational activities that it alleged were inconsistent with earlier studies. PTFI and the MOEF also established a framework known as the Tailings Management Roadmap for continuous improvement in environmental practices and tailings management at PTFI’s Grasberg operations. PTFI completed the Tailings Management Roadmap commitments for the 2018 through 2024 period. The current phase of the Tailings Management Roadmap, approved by MOEF in 2024, extends from 2025 through 2030 and builds upon activities from the initial period. In 2025, PTFI continued to work with MOEF on the primary Tailings Management Roadmap objectives, including (1) the reduction of non-tailings sediment entering the tailings management area, (2) the increased retention, flow control and distribution of tailings within the tailings management area and (3) the pursuit of additional beneficial uses of tailings in infrastructure and other projects. In 2020, PTFI initiated a new environmental impact analysis (called an Analisis Mengenai Dampak Lingkungan or AMDAL) in preparation for the proposed activities associated with the transition from Grasberg surface mine to underground operations, and PTFI completed the approval requirements of the AMDAL covering all support activities for the underground transition in 2023. In December 2023, PTFI received technical approval for its tailings management activities. In 2024, the MOEF approved an addendum to the AMDAL that covers activities associated with the conversion of PTFI’s power plant from coal-fired to liquefied natural gas (LNG). Permitting related to the conversion to LNG continues to progress. 8 8 8 8 8 8 Table of Contents Table of Contents Table of Contents In accordance with Indonesia law, in 2019, PTFI completed and Indonesia regulators approved an updated mine closure plan to reflect Grasberg minerals district production operations until 2041. In the future, additional approval will be required for the diversion of the Aghawagon/Otomona River out of the tailings management area at the end of the mine life. In 2022, PTFI received approval on its reclamation plan through 2026. PTFI has provided all required mine closure and reclamation guarantees in the form of time deposits and bank guarantees with state-owned banks in accordance with prevailing regulations. Climate In many of the jurisdictions in which we or our customers operate, governmental bodies and governmental officials have enacted or proposed legislation, regulations and policies in response to the potential impacts of climate change. For example, carbon tax legislation has been adopted in jurisdictions where we operate, including Indonesia, Chile and the European Union (EU). PTFI’s coal-fired power plant was not within the scope of Indonesia’s carbon emissions trading system in 2025. PTFI continues to monitor the regulation. Refer to “Operations – Indonesia” below for discussion of PTFI’s plans to transition its existing energy source from coal to natural gas. Further, certain jurisdictions, including the EU and California, have introduced or passed regulations that may require corporate climate-related reporting as specified by the individual regulations. While it is not possible to reasonably estimate the nature, extent, scope, timing and cost or other impacts of any current or future carbon pricing mechanisms, mandatory disclosures, other climate change regulatory programs or future legislative action that may be enacted, we anticipate that we will dedicate more resources and incur more costs to comply and remediate in response to legislative or regulatory changes. For information about the risks posed by the potential impacts of climate change and related regulations, refer to Item 1A. “Risk Factors.”"

      "prior_title": null,
      "current_body": "In 2025, our costs were not significantly impacted by U.S. tariffs, and we are continuing to monitor the impacts on our business, cost structure and supply chains associated with tariffs on U.S. imports. Efforts continue to identify alternative sourcing options to mitigate potential future impacts of tariffs. Effective August 1, 2025, a 50% tariff was imposed under Section 232 of the Trade Expansion Act, targeting U.S. imports of semi-finished copper products and copper-intensive derivative products. However, refined copper, including cathodes, concentrates and scrap, was exempted from the tariff, and the U.S. government has indicated it will reassess by mid-2026 the potential for a refined copper tariff of 15% beginning in January 2027 and rising to 30% in 2028. Refer to “Markets” in MD&A for further discussion of LME and COMEX copper prices. Additionally, the U.S. Secretary of Commerce was directed to impose requirements that 25% of copper cathode and concentrate produced in the U.S. be sold domestically in 2027, potentially increasing to 30% in 2028 and 40% in 2029. Because of our integrated operations, these requirements are not expected to impact our business. We are the leading copper supplier in the U.S., providing approximately 70% of total U.S. refined copper production through our integrated domestic mining and processing facilities, and most of which is sold domestically. For the year 2025, copper from our U.S. mining operations was sold 66% as rod, 25% as cathode and 9% in concentrate. We are well positioned in the U.S. with sizeable resources and opportunities to leverage existing infrastructure through brownfield expansions. Government action related to tariffs and other controls on imports and exports or trade agreements or policies are difficult to predict and may continue to cause significant volatility in our financial performance and in the trading prices of our common stock.

      "current_title": "The mud removal and other remediation activities, and the phased restart and ramp-up of the Grasberg Block Cave underground mine following the September 2025 mud rush incident may not be achieved as planned which could adversely impact our results of operations and financial condition.",
      "prior_title": null,
      "current_body": "On September 8, 2025, PTFI experienced an unprecedented mud rush incident, during which approximately 800,000 metric tons of wet material entered the Grasberg Block Cave underground mine from the former Grasberg open pit and traveled rapidly to multiple levels of the mine, including a service level where seven team members were later found deceased. Mining operations were temporarily suspended to prioritize the recovery of the seven team members fatally injured during the incident and to conduct investigations. Following the September 2025 mud rush incident, PTFI has been engaged in activities to address the incident and advance preparation for a safe and sustainable restart of operations. In late October 2025, PTFI restarted operations at the unaffected Deep Mill Level Zone (DMLZ) and Big Gossan underground mines. Investigations and remedial plans were completed in fourth-quarter 2025 and a phased restart and ramp-up of the Grasberg Block Cave underground mine is anticipated to begin in second-quarter 2026. The incident impacted our results for the second half of 2025, and we expect the incident to have a significant impact on our 2026 operating and financial results. We plan to implement enhanced operating procedures to address the conditions that led to the incident and use information from this unprecedented incident to further enhance risk management processes, including ongoing management and stabilization of conditions in the open pit. Material changes to our operating plans could affect our mineral reserves. In addition, there can be no assurance that other unforeseeable incidents will not occur in the future. 58 58 58 58 58 58 Table of Contents Table of Contents Table of Contents Mud removal is in process and other steps necessary for restart and ramp-up of operations, including implementation of enhanced operating procedures to address the conditions that led to the incident, development of updated cave management plans and draw protocols, and design, construction, repair and replacement of damaged infrastructure and equipment, are expected to begin in the near term. The timing of the phased restart and ramp-up of certain areas of the Grasberg Block Cave underground mine could be impacted by any delay in the removal and remediation activities. Further, new or additional operational challenges could arise as we progress mud removal and other remediation activities and the phased restart and ramp-up of the Grasberg Block Cave underground mine. Refer to MD&A and Note 10 for discussion of asset impairment charges recorded as a result of damage assessments and evaluation of the affected infrastructure. We do not believe there has been a broader impairment of PTFI’s long-lived mining assets based on PTFI’s reserve life, favorable market outlook for metal prices and the expected resumption of operations at the Grasberg Block Cave underground mine; however, changes to our estimates of recoverable proven and probable mineral reserves or declines in the prices of commodities PTFI sells could have an impact on the future recoverability assessments of PTFI’s long-lived mining assets. PTFI has recorded charges and expects to incur additional costs related to the incident in the future. Any future costs, liabilities, fines, penalties and financial impacts resulting from the incident and any related investigations or claims may exceed our current expectations and any insurance recoveries. PTFI has submitted a claim to seek recovery of damages under its property and business interruption insurance policies. PTFI’s ability to recover damages under its insurance coverage with respect to the incident is subject to certain conditions, and the scope of insured losses and timing of recovery is undetermined. In addition, there can be no assurance that such insurance will continue to be available at economically feasible premiums for certain related risks. To the extent insurance proceeds are delayed or disputed, we may be required to fund repairs and related costs from available cash flows or borrowings. Further, government agencies may impose changes to applicable laws, regulations or environmental requirements or new standards as a result of the incident. In addition, we may experience adverse indirect effects on our business, including negative publicity, damage to our reputation, increased scrutiny by regulators and investors, and reduced confidence from our workforce, local communities, customers and other stakeholders. As a result of the incident and impact on operations, PTFI notified certain commercial counterparties of a force majeure under its contracts, which may negatively impact PTFI’s relationships with such counterparties. Although the declaration of force majeure for certain PTFI contracts has not materially impacted PTFI’s contractual obligations to date, such obligations could be negatively impacted by the incident or any similar future incidents. Any of the above could adversely affect our cash flows, access to capital, development projects, capital expenditures, results of operations and financial condition."

      "current_body": "Mining operations on the scale of our Indonesia operations involve significant environmental risks and challenges. Given the unique site-specific topographical, hydrological and geotechnical conditions of the project area, a major challenge is to dispose of the large volume of tailings we produce. In 2025, PTFI produced approximately 48 million metric tons of tailings. Our tailings management plan, which has been approved by the Indonesia government, uses an unnavigable part of a river in the highlands to transport the tailings and natural sediments from the mill in the highlands to an engineered tailings management area in the lowlands. Levees have been constructed along both sides of the lowlands tailings management area to act as containment structures to laterally contain the depositional footprint of the tailings and natural sediment within the approved tailings management area. 61 61 61 61 61 61 Table of Contents Table of Contents Table of Contents Another major environmental challenge at PTFI is managing overburden stockpiles and other waste rock and conditions in the open pit. Overburden is rock that was previously moved aside in the Grasberg open pit mining process to reach the ore. In the presence of air, water and naturally occurring bacteria, some of this material can generate acid rock drainage (acidic water containing dissolved metals) that, if not properly managed, can adversely affect the environment or be costly to manage. There is no guarantee our actions to prevent and manage the quality of any discharge of impacted water will be successful. PTFI may modify its re-sloping, erosion control and water management plans in the future, which could lead to material increases in costs. In addition, in the past, certain Grasberg overburden stockpiles experienced erosion over time that caused mineralized overburden material to enter into the lowlands tailings management area. This erosion affected the volume as well as the physical and chemical characteristics of the sediment material deposited in the lowlands tailings management area, which, if not properly managed, could result in environmental impacts. The underlying overburden erosion and run-off are being managed and controlled through an extensive re-sloping and water management project which is ongoing, and PTFI has not experienced similar erosion issues since 2018. PTFI maintains a tailings deposition management plan and environmental monitoring program which consider the presence of this potentially acid-forming overburden in the lowlands tailings management area. PTFI has expanded the scope of its environmental monitoring program which assesses potential environmental and human health impacts from overburden and tailings. As part of the expanded scope, in 2022 and 2023, PTFI assisted the Mimika local health authority (LHA) with broad-based community health surveys, which provided further data on an extensive range of community health issues. There were no impacts attributable to PTFI’s operations (inclusive of tailings and overburden) that were determined to be a priority focus of the LHA following the results of these assessments. During 2025, PTFI continued its routine assessments of surface waters, groundwaters, sediments and soils, dust and terrestrial and aquatic tissues. In the past, the Indonesia government, stakeholders and other third parties have raised questions with respect to PTFI’s tailings management systems and plans. We continue to revisit studies for alternative tailings management options. Our Indonesia mining operations are remotely located in steep mountainous terrain and in an active seismic area, which also experiences extreme weather events. Independent environmental management expert audits have reaffirmed conclusions from previous studies that PTFI’s controlled riverine tailings management system represents the best alternative for tailings management given the volume of tailings produced and the site-specific conditions of the area. Overtopping or failure of any of the PTFI tailings containment structures (levees or protection structures) induced by extreme weather events such as floods, a major seismic event or naturally occurring weak ground under the structures, are potential risks. The potential impacts from any such occurrence could vary significantly depending upon the specific location of the failure. Unanticipated structural failure of these structures in certain areas in the future could result in flooding of the nearby communities and related loss of lives and/or severe personal, property and environmental damages. Under certain conditions, a failure may necessitate evacuation or relocation of communities or other emergency action, financial assistance to the communities impacted, and remediation costs to repair and compensate for the social, cultural and economic impacts associated with such failure. In addition, in the southern (estuary) portion of the approved tailings management area, modeling of sediment transport scenarios indicates that tailings have the potential to be deposited outside of the approved lateral levees in adjacent mangroves. PTFI has proposed additional extensions to the existing levees to the Indonesia regulators and is further evaluating the potential benefits and impacts. Indonesia regulators have further proposed a different strategy involving efforts to increase sediment retention through various methods as well as increase beneficial use of tailings. If the additional retention efforts are not successful, or if the permitting for these proposed protection structures is not reconsidered, any such depositional impacts outside of our existing approved footprint could impact the environment and communities. Refer to Items 1. and 2. “Business and Properties” for further discussion of our environmental obligations in Indonesia. Managing these environmental challenges at our Indonesia operations could result in reputational harm, social unrest and increased costs that could be significant. There can be no assurance that future changes in environmental laws or regulations affecting the mining industry in Indonesia will not be introduced or unexpectedly altered or repealed, or that new interpretations of existing Indonesia environmental laws and regulations will not be issued, which could have a significant impact on PTFI. 62 62 62 62 62 62 Table of Contents Table of Contents Table of Contents",

The timing and amounts of estimated payments could change as a result of changes in regulatory requirements, changes in scope and costs of reclamation activities, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters. For example, revised federal regulations governing hazardous air pollutant emissions at our Miami, Arizona smelter were finalized in May 2024 and are under evaluation. We are also subject to extensive regulation of worker health and safety. Our mines are inspected on a regular basis by government regulators who may issue citations and orders when they believe a violation has occurred under applicable mining regulations. If inspections result in an alleged violation, we may be subject to fines and penalties and, in instances of alleged significant violations, our mining operations or industrial facilities could be subject to temporary or extended closures. Many other governmental bodies regulate other aspects of our operations, and our failure to comply with these legal requirements can result in substantial penalties. In addition, new laws and regulations, including executive orders, or changes to or new interpretations of existing laws and regulations by courts or regulatory authorities occur regularly, but are difficult to predict. For instance, the U.S. Supreme Court’s 2024 decision in Loper Bright Enterprises v. Raimondo (Loper Bright) overruled Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. (Chevron). Since 1984, Chevron had required courts to give judicial deference to administrative agency actions and reasonable agency interpretations where a statute was silent or ambiguous. In Loper Bright, the Supreme Court held that the U.S. Administrative Procedure Act requires courts to exercise independent judgment when deciding whether an agency acted within its statutory authority and that courts may not defer to agency interpretations solely because a statute is ambiguous. This decision may result in additional legal challenges to regulations and guidance issued by federal regulatory agencies, including those that impact our industry. Changes under a new president, administration and Congress in the U.S. are also difficult to predict. Any such variations could negatively impact the mining sector, including our business, substantially increase costs to achieve compliance or otherwise have a material adverse effect on our cash flows, results of operations and financial condition. For additional information regarding the various regulations affecting us, see Items 1. and 2. “Business and Properties.”"

(21.0%), Compañia de Minas Buenaventura S.A.A. (19.58%) and other stockholders whose Cerro Verde shares are publicly traded on the Lima Stock Exchange (4.34%). Cerro Verde is an open-pit copper and molybdenum mining complex that has been in operation since the 1970s. Cerro Verde is located 20 miles southwest of Arequipa, Peru. Prior to being acquired in 1994 by a predecessor of Phelps Dodge, the mine was previously operated by the Peru government. The property is located at latitude 16.53 degrees south and longitude 71.58 degrees west using the WGS 84 coordinate system. The site is accessible by paved highways. Cerro Verde’s copper cathode and concentrate production that is not sold locally is transported approximately 70 miles by truck and by rail to the Port of Matarani for shipment to international markets. Molybdenum concentrate is transported by truck to either the Ports of Callao or Matarani for shipment. 19 19 19 19 19 19 Table of Contents Table of Contents Table of Contents The Cerro Verde mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper “pitch.” Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite, minor bornite and molybdenite are the dominant primary sulfides. Cerro Verde’s operation includes two concentrating facilities with an annual average permitted milling capacity of 409,500 metric tons of ore per day (and the ability to annually treat up to 10% more for a total of 450,450 metric tons of ore per day). Cerro Verde also operates a 100,000-metric-ton-per-day ROM leach system coupled with SX/EW leaching facilities, which have a production capacity of approximately 200 million pounds of copper per year. The available fleet consists of fifty-four 300-metric-ton haul trucks, ninety-one 250-metric-ton haul trucks (19 of which are currently on standby) and twenty 380-metric-ton haul trucks (13 of which are currently leased) loaded by 14 electric shovels with bucket sizes ranging from 33 to 57 cubic meters. This fleet is capable of moving an average of approximately 1,000,000 metric tons of material per day. At December 31, 2025, Cerro Verde’s net PP&E and mine development costs totaled $5.8 billion. Cerro Verde’s production totaled 0.9 billion pounds of copper and 21 million pounds of molybdenum in 2025, 0.9 billion pounds of copper and 20 million pounds of molybdenum in 2024, and 1.0 billion pounds of copper and 22 million pounds of molybdenum in 2023. Cerro Verde is located in a desert environment with rainfall averaging less than two inches per year and is in an active seismic zone. The highest bench elevation is 2,723 meters above sea level and the ultimate pit bottom is expected to be 1,538 meters above sea level. The Peru general mining law and Cerro Verde’s mining stability agreement grant the surface rights of mining concessions located on government land. Government land obtained after 1997 must be leased or purchased. Cerro Verde has a mining concession covering approximately 178,700 acres, including 61,500 acres of surface rights and access to 14,600 acres granted through an easement from the Peru National Assets Office, plus 151 acres of owned property, and 1,065 acres of rights-of-way outside the mining concession area leased from both government agencies and private parties. Cerro Verde currently receives electrical power, including hydro-generated power, under long-term contracts with ElectroPerú S.A. and Engie Energía Peru S.A. During 2023, Cerro Verde entered into a new power purchase agreement that is expected to transition its electric power to fully renewable energy sources in 2026. Water for our Cerro Verde processing operations comes from renewable sources through a series of storage reservoirs on the Río Chili watershed that collect water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant originally constructed and currently operated by Cerro Verde. In December 2025, Cerro Verde entered into an agreement with SEDAPAR, the municipal water and sanitation services provider in the Arequipa region, to expand the existing wastewater treatment plant and complete additional infrastructure projects, for the benefit of Arequipa’s population (refer to Note 11 for further discussion). We believe the Cerro Verde operation has sufficient water sources to support current operations, but we are closely monitoring ongoing weather patterns. Refer to “Governmental Regulations” above and Item 1A. “Risk Factors” for further discussion. 20 20 20 20 20 20 Table of Contents Table of Contents Table of Contents El Abra We have a 51% ownership interest in El Abra, and the remaining 49% interest is held by the state-owned copper enterprise Corporación Nacional del Cobre de Chile. El Abra is an open-pit copper mining complex that has been in operation since 1996. El Abra is located 47 miles north of Calama in Chile’s El Loa province of the northern Chilean region of Antofagasta. The site is accessible by paved highways and by rail. The El Abra mine is a porphyry copper deposit that has sulfide and oxide mineralization. The predominant primary sulfide copper minerals are bornite and chalcopyrite. There is a minor amount of secondary sulfide mineralization as chalcocite. The oxide copper minerals are chrysocolla and pseudomalachite. There are lesser amounts of copper-bearing clays and tenorite. The El Abra operation consists of a SX/EW facility with a capacity of 500 million pounds of copper cathode per year from a 115,000-metric-ton-per-day crushed leach circuit and a ROM leaching operation. The available fleet consists of twenty-three 242-metric-ton haul trucks loaded by 4 electric shovels with buckets ranging in size from 29 to 41 cubic meters, which are capable of moving 217,000 metric tons of material per day. At December 31, 2025, El Abra’s net PP&E and mine development costs totaled $0.9 billion. El Abra’s copper production totaled 201 million pounds in 2025, 219 million pounds in 2024 and 217 million pounds in 2023. We have completed substantial drilling and evaluations and have identified a large sulfide reserve in support of a potential major mill project similar to the large-scale concentrator at Cerro Verde. The project could result in the addition of over 700 million pounds of copper production per year. We have advanced preparation of our permitting application and plan to submit an environmental impact statement to Chile regulatory authorities in the first half of 2026. Preliminary estimates, which remain under review, indicate that the project economics would be supported using an incentive copper price of less than $4.00 per pound. The decision to proceed with and timing of the potential project will take into account overall copper market conditions, required permitting and other factors. El Abra is located in a desert environment with rainfall averaging less than one inch per year and is in an active seismic zone. The highest bench elevation is 4,225 meters above sea level and the ultimate pit bottom is expected to be 3,325 meters above sea level. El Abra controls a total of approximately 183,700 acres of mining claims covering the ore deposit, stockpiles, process plant, and water wellfield and pipeline. El Abra also has land surface rights for the road between the processing plant and the mine, the water wellfield, power transmission lines and for the water pipeline from the Salar de Ascotán aquifer. El Abra receives electrical power generated from renewable sources under a long-term contract with Engie Energía Chile S.A. Water for our El Abra processing operations currently comes from the continued pumping of groundwater from the Salar de Ascotán aquifer pursuant to regulatory approval. We believe El Abra has sufficient water sources to support current operations, although we are evaluating options for water infrastructure alternatives to provide 21 21 21 21 21 21 Table of Contents Table of Contents Table of Contents options to extend existing operations and support a future expansion. Refer to “Governmental Regulations” above and Item 1A. “Risk Factors” for further discussion. Indonesia Ownership. PTFI is a limited liability company organized under the laws of the Republic of Indonesia. On December 21, 2018, we completed the transaction with the Indonesia government regarding PTFI’s long-term mining rights and share ownership (the 2018 Transaction). Following the 2018 Transaction, we have a 48.76% share ownership in PTFI and the remaining 51.24% share ownership is collectively held by PT Mineral Industri Indonesia (MIND ID), an Indonesia state-owned enterprise, and PT Indonesia Papua Metal Dan Mineral (formerly known as PT Indocopper Investama), which is expected to be owned by MIND ID and the provincial/regional government in Central Papua, Indonesia. IUPK. Concurrent with closing the 2018 Transaction, the Indonesia government granted PTFI an IUPK to replace its former contract of work. Under the terms of the IUPK, PTFI has been granted an extension of mining rights through 2031, with rights to extend mining rights through 2041, subject to PTFI completing the construction of additional domestic smelting and refining capacity in Indonesia and fulfilling its defined fiscal obligations to the Indonesia government. The IUPK, and related documentation, contains legal and fiscal terms and is legally enforceable through 2041. In addition, we, as a foreign investor, have rights to resolve investment disputes with the Indonesia government through international arbitration. Pursuant to regulations issued during 2024, PTFI is eligible to apply for an extension of its mining rights beyond 2041, provided certain conditions are met. The application for extension may be submitted at any time up to one year prior to the expiration of the current IUPK. With the completion of PTFI’s downstream processing facilities during 2025, we and PTFI have advanced discussions with the Indonesia government for a long-term extension of PTFI’s operating rights beyond the current expiration in 2041. An extension would enable continuity of large-scale operations for the benefit of all stakeholders and provide growth options through additional resource development opportunities in the highly attractive Grasberg minerals district. PTFI is preparing its application for a long-term extension expected to cover the life of the resource, which is expected to be submitted during 2026. In connection with the extension, PTFI would pursue additional exploration, conduct studies for future additional development and expand its social programs. We expect to maintain our ownership interest in PTFI of approximately 49% through 2041 and hold approximately 37% beginning in 2042, following the transfer of an additional interest to an Indonesia state-owned enterprise. We expect the existing governance agreements would continue over the life of the resource. 22 22 22 22 22 22 Table of Contents Table of Contents Table of Contents Refer to Item 1A. “Risk Factors” and Notes 10 and 11 for discussion of PTFI’s IUPK, export licenses and risks associated with our Indonesia operations. Grasberg Minerals District Mud Rush Incident. On September 8, 2025, PTFI experienced an external mud rush incident that resulted in seven fatalities. Mining operations were temporarily suspended to prioritize the recovery of the seven team members fatally injured and to conduct investigations. Following the incident, PTFI has been engaged in activities to address the incident and advance preparation for a safe and sustainable restart of operations. In late October 2025, PTFI restarted operations at the unaffected DMLZ and Big Gossan underground mines. Investigations and remedial plans were completed in fourth-quarter 2025 and a phased restart and ramp-up of the Grasberg Block Cave underground mine is anticipated to begin in second-quarter 2026. The plan includes a restart of Production Blocks 2 and 3 in second-quarter 2026 and the potential restart of operations in Production Block 1 during 2027. Based on current estimates, PTFI expects approximately 85% of its total production at normal operating rates to be restored in the second half of 2026. Key milestones required for initiating production in Production Blocks 2 and 3, including mud removal in mine workings, repairs of supporting infrastructure and installation of protective barriers, are progressing on schedule. Refer to Note 10 for further discussion. Downstream Processing Facilities. PTFI’s smelter and PT Smelting smelt and refine all of the copper concentrate from PTFI, and the PMR processes anode slimes from the smelter and PT Smelting. With the completion of its downstream processing facilities during 2025, PTFI became a fully integrated producer of refined copper and gold. Refer to “Other Smelting Facilities and Mining Properties” below for further discussion of PT Smelting. During 2024, construction of PTFI’s smelter in Eastern Java, Indonesia, was completed. In October 2024, during start-up activities, a fire occurred that required a temporary suspension of smelting operations to complete repairs. Operations commenced in May 2025 following completion of repairs, and in July 2025, PTFI’s smelter produced its first copper cathode. Following the September 2025 mud rush incident, smelting operations in Indonesia at both PTFI’s smelter and PT Smelting were temporarily suspended during fourth-quarter 2025 as a result of limited copper concentrate availability. PT Smelting restarted operations in late December 2025 and is expected to operate at reduced rates pending the anticipated second-quarter 2026 restart of mining at the Grasberg Block Cave underground mine. Shipments to PTFI’s smelter are expected to recommence in the second half of 2026, pending the successful ramp up of mining operations. PTFI’s smelter has a capacity to process approximately 1.7 million metric tons of copper concentrate per year. In 2025, copper anode production from PTFI’s smelter totaled 54,100 metric tons and copper cathode production from its refinery totaled 42,600 metric tons. As part of start-up activities, PTFI commenced gold production from the PMR in December 2024 and operated on a limited basis during 2025, primarily processing anode slimes from PT Smelting. The PMR has a design capacity to refine anode slimes from PTFI’s smelter as well as from PT Smelting. Anode slimes processed through the PMR totaled 1,900 metric tons in 2025. Refer to Item 1A. “Risk Factors,” MD&A and Notes 10 and 11 for additional discussion of PTFI’s downstream processing facilities. Grasberg Minerals District. PTFI operates in the remote highlands of the Sudirman Mountain Range in the province of Central Papua, Indonesia, which is on the western half of the island of New Guinea. Since 1967, we and our predecessors have been the only operator of exploration and mining activities in the approximately 24,600-acre operating area. The operating area is accessible by coastal portsite facilities on the Arafura Sea and by the Timika airport. The project site is located at latitude 4.08 degrees south and longitude 137.12 degrees east using the WGS 84 coordinate system. The project area includes a 70-mile main service road from portsite to the mill complex. At December 31, 2025, PTFI’s net PP&E and mine development costs, including the downstream processing facilities, totaled $22.2 billion. 23 23 23 23 23 23 Table of Contents Table of Contents Table of Contents Over a multi-year investment period, PTFI has successfully commissioned three large-scale underground mines in the Grasberg minerals district (Grasberg Block Cave, DMLZ and Big Gossan) and related expansion of the milling facilities. At normal operating rates, PTFI’s underground operations produce approximately 1.7 billion pounds of copper and 1.3 million ounces of gold per year and are among the lowest cost operations in the world. Production from these underground mines is expected to continue through 2041 and an extension of PTFI’s operating rights beyond 2041 would extend the lives of these mines. PTFI is also conducting exploration in the Grasberg minerals district targeting the potential extension of significant mineralization below the DMLZ underground mine. Milling rates for ore from these underground mines averaged 138,100 metric tons of ore per day in 2025, 208,400 metric tons of ore per day in 2024 and 198,300 metric tons of ore per day in 2023. Production from the Grasberg minerals district totaled 1.0 billion pounds of copper and 0.9 million ounces of gold in 2025, 1.8 billion pounds of copper and 1.9 million ounces of gold in 2024, and 1.7 billion pounds of copper and 2.0 million ounces of gold in 2023. Lower milling rates and production volumes in 2025, compared to 2024 and 2023, reflect the impact of the September 2025 mud rush incident. Refer to Item 1A. “Risk Factors” for discussion of risks associated with development projects and underground mines. PTFI plans to transition its existing energy source from coal to natural gas, which would meaningfully reduce PTFI’s greenhouse gas emissions at the Grasberg minerals district. Following the September 2025 mud rush incident, PTFI’s planned investments for a new gas-fired combined cycle facility have been deferred with start-up and commissioning of the new facility scheduled in the second half of 2029. Once complete, PTFI’s dual-fuel power plant and the new gas-fired combined cycle facility will be fueled by natural gas supplied by a floating LNG storage and regassification unit. A combination of naturally occurring mountain streams and water derived from PTFI’s underground operations provides water for its operations. Our Indonesia operations are in an active seismic zone and experience average annual rainfall of approximately 200 inches. Grasberg Block Cave Underground Mine The Grasberg Block Cave ore body is the same ore body historically mined from the surface in the Grasberg open pit. At December 31, 2025, the Grasberg Block Cave underground mine had 470 open drawbells. Undercutting, drawbell construction and ore extraction activities in the Grasberg Block Cave underground mine have been temporarily suspended following the September 2025 mud rush incident. A phased restart and ramp-up of the Grasberg Block Cave underground mine is anticipated to begin in second-quarter 2026. Ore milled from the Grasberg Block Cave underground mine averaged 78,400 metric tons per day in 2025, 133,800 metric tons per day in 2024 and 117,300 metric tons per day in 2023. The Grasberg Block Cave fleet consists of approximately 520 pieces of mobile equipment. The primary mining equipment directly associated with production and development includes an available fleet of 66 LHD units and 16 haul trucks. Each production LHD unit typically carries approximately 9 metric tons of ore and transfers ore into the rail haulage system. The Grasberg Block Cave has an automated rail haulage system with 14 locomotives and 160 ore wagons that haul the ore to 3 gyratory crushers located underground. Each ore wagon typically carries 35 metric tons. The crushed ore is conveyed to surface stockpiles for processing. DMLZ Underground Mine The DMLZ ore body lies below the depleted Deep Ore Zone underground mine at the 2,590-meter elevation and represents the downward continuation of mineralization in the Ertsberg East Skarn system and neighboring Ertsberg porphyry. Hydraulic fracturing operations have been effective in managing rock stresses and pre-conditioning the cave following mining-induced seismic activity experienced from time to time. At December 31, 2025, the DMLZ underground mine had 174 open drawbells. 24 24 24 24 24 24 Table of Contents Table of Contents Table of Contents Ore milled from the DMLZ underground mine averaged 54,300 metric tons per day in 2025, 64,900 metric tons per day in 2024 and 75,900 metric tons per day in 2023. The DMLZ fleet consists of approximately 327 pieces of mobile equipment, which includes 64 LHD units and 33 haul trucks used in production and development activities. Each production LHD unit typically carries approximately 9 metric tons of ore and transfers ore into the truck haulage system. The haul trucks have a capacity of 55 to 60 metric tons and load ore from chutes fed by the LHDs and transfer it to one of two gyratory crushers. The crushed ore is conveyed to surface stockpiles for processing. Big Gossan Underground Mine The Big Gossan ore body lies underground and adjacent to the current mill site. It is a tabular, near vertical ore body with approximate dimensions of 1,200 meters along strike and 800 meters down dip with varying thicknesses from 20 meters to 120 meters. The mine utilizes a blasthole stoping method with delayed paste backfill. Stopes of varying sizes are mined and the ore dropped down passes to a truck haulage level. Trucks are chute loaded and transport the ore to a jaw crusher. The crushed ore is then hoisted vertically via a two-skip production shaft to a level where it is loaded onto a conveyor belt. The belt carries the ore to one of the main underground conveyors where the ore is transferred and conveyed to the surface stockpiles for processing. Ore milled from the Big Gossan underground mine averaged 6,000 metric tons per day in 2025, 8,000 metric tons per day in 2024 and 7,900 metric tons per day in 2023. The Big Gossan fleet consists of approximately 73 pieces of mobile equipment, which includes 11 LHD units and 8 haul trucks used in development and production activities. Kucing Liar Underground Mine Since 2022, PTFI has conducted long-term mine development activities at its Kucing Liar deposit in the Grasberg minerals district. During 2025, PTFI completed studies to evaluate the potential to expand the footprint of the deposit which was previously designed to operate at a long-term rate of 90,000 metric tons of ore per day. The studies identified a low-cost expansion opportunity to increase Kucing Liar’s design capacity to 130,000 metric tons of ore per day and increase Kucing Liar’s reserves by approximately 20%. At December 31, 2025, PTFI’s preliminary estimates of Kucing Liar reserves approximate 8 billion pounds of copper and 8 million ounces of gold to be recovered through 2041, an increase from previous estimates of 7 billion pounds of copper and 6 million ounces of gold. Under the new design, average Kucing Liar production at full rates would approximate 750 million pounds of copper and 735 thousand ounces of gold (an increase of more than 35% from prior estimates). The economic studies took into account an approximate 10% increase in Kucing Liar capital ($0.5 billion), impact to operating rates at the Grasberg Block Cave underground mine and reduction of capital expenditures associated with PTFI’s mine operations in connection with the processing of higher pyrite ore. At December 31, 2025, PTFI had incurred approximately $1.1 billion for Kucing Liar, and capital investments are estimated to approximate an additional $4 billion through 2033 (averaging approximately $0.5 billion per year). Initial production is expected to commence ramping up in the 2030 timeframe. Description of Indonesia Ore Bodies. Our Indonesia ore bodies are located within and around two main igneous intrusions, the Grasberg monzodiorite and the Ertsberg diorite. The host rocks of these ore bodies include both carbonate and clastic rocks that form the ridge crests and upper flanks of the Sudirman Range, and the igneous rocks of monzonitic to dioritic composition that intrude them. The igneous-hosted ore bodies (the Grasberg Block Cave and portions of the DMLZ) occur as vein stockworks and disseminations of copper sulfides, dominated by chalcopyrite and, to a lesser extent, bornite. The sedimentary-rock hosted ore bodies (portions of the DMLZ and Kucing Liar and all of the Big Gossan) occur as “magnetite-rich, calcium/magnesian skarn” replacements, whose location and orientation are strongly influenced by major faults and by the chemistry of the carbonate rocks along the margins of the intrusions. The copper mineralization in these skarn deposits is dominated by chalcopyrite, but higher bornite concentrations are common. Moreover, gold occurs in significant concentrations in all of the district’s ore bodies, though rarely visible to the naked eye. These gold concentrations usually occur as inclusions within the copper sulfide minerals, though, in some deposits, these concentrations can also be strongly associated with pyrite. 25 25 25 25 25 25 Table of Contents Table of Contents Table of Contents The following diagram indicates the relative elevations (in meters) of our reported Indonesia ore bodies.

      "prior_body": "In September 2024, we purchased 5.3 million shares of Cerro Verde common stock for $210 million, increasing our ownership interest in Cerro Verde to 55.08% from 53.56%. The remaining 44.92% ownership interest in Cerro Verde is held by SMM Cerro Verde Netherlands B.V. (21.0%), Compañia de Minas Buenaventura S.A.A. (19.58%) and other stockholders whose Cerro Verde shares are publicly traded on the Lima Stock Exchange (4.34%). Cerro Verde is an open-pit copper and molybdenum mining complex that has been in operation since the 1970s. Cerro Verde is located 20 miles southwest of Arequipa, Peru. Prior to being acquired in 1994 by a predecessor of Phelps Dodge, the mine was previously operated by the Peru government. The property is located at latitude 16.53 degrees south and longitude 71.58 degrees west using the WGS 84 coordinate system. The site is accessible by paved highways. Cerro Verde’s copper cathode and concentrate production that is not sold locally is transported approximately 70 miles by truck and by rail to the Port of Matarani for shipment to international markets. Molybdenum concentrate is transported by truck to either the Ports of Callao or Matarani for shipment. 18 18 18 18 18 18 Table of Contents Table of Contents Table of Contents The Cerro Verde mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper “pitch.” Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite and molybdenite are the dominant primary sulfides. Cerro Verde’s operation includes 2 concentrating facilities with an annual average permitted milling capacity of 409,500 metric tons of ore per day (and the ability to annually treat up to 10% more for a total of 450,450 metric tons of ore per day). As a result of several efficiency initiatives implemented over the past several years, in 2024, Cerro Verde’s 2 concentrators were able to achieve a combined average milling rate of 415,500 metric tons of ore per day in 2024. Cerro Verde also operates a 100,000-metric-ton-per-day ROM leach system coupled with SX/EW leaching facilities, which have a production capacity of approximately 200 million pounds of copper per year. The available fleet consists of fifty-four 300-metric-ton haul trucks, ninety-one 250-metric-ton haul trucks (8 of which are currently on standby) and 8 leased 380-metric-ton haul trucks loaded by 14 electric shovels with bucket sizes ranging from 33 to 57 cubic meters. This fleet is capable of moving an average of approximately 1,000,000 metric tons of material per day. Cerro Verde’s net PP&E and mine development costs at December 31, 2024, totaled $5.8 billion. Cerro Verde’s production totaled 0.9 billion pounds of copper and 20 million pounds of molybdenum in 2024, 1.0 billion pounds of copper and 22 million pounds of molybdenum in 2023, and 1.0 billion pounds of copper and 23 million pounds of molybdenum in 2022. Cerro Verde is located in a desert environment with rainfall averaging less than two inches per year and is in an active seismic zone. The highest bench elevation is 2,768 meters above sea level and the ultimate pit bottom is expected to be 1,538 meters above sea level. The Peru general mining law and Cerro Verde’s mining stability agreement grant the surface rights of mining concessions located on government land. Government land obtained after 1997 must be leased or purchased. Cerro Verde has a mining concession covering approximately 175,500 acres, including 61,500 acres of surface rights and access to 14,600 acres granted through an easement from the Peru National Assets Office, plus 151 acres of owned property, and 1,065 acres of rights-of-way outside the mining concession area leased from both government agencies and private parties. Cerro Verde currently receives electrical power, including hydro-generated power, under long-term contracts with ElectroPerú S.A. and Engie Energía Peru S.A. During 2023, Cerro Verde entered into a new power purchase agreement that is expected to transition its electric power to fully renewable energy sources in 2026. Water for our Cerro Verde processing operations comes from renewable sources through a series of storage reservoirs on the Río Chili watershed that collect water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant originally constructed and currently operated by Cerro Verde. We believe the Cerro Verde operation has sufficient water sources to support current operations, but we are closely monitoring ongoing weather patterns. Refer to “Governmental Regulations” above and Item 1A. “Risk Factors” for further discussion. 19 19 19 19 19 19 Table of Contents Table of Contents Table of Contents El Abra We have a 51% ownership interest in El Abra, and the remaining 49% interest is held by the state-owned copper enterprise Corporación Nacional del Cobre de Chile. El Abra is an open-pit copper mining complex that has been in operation since 1996. El Abra is located 47 miles north of Calama in Chile’s El Loa province of the northern Chilean region of Antofagasta. The site is accessible by paved highways and by rail. The El Abra mine is a porphyry copper deposit that has sulfide and oxide mineralization. The predominant primary sulfide copper minerals are bornite and chalcopyrite. There is a minor amount of secondary sulfide mineralization as chalcocite. The oxide copper minerals are chrysocolla and pseudomalachite. There are lesser amounts of copper bearing clays and tenorite. The El Abra operation consists of a SX/EW facility with a capacity of 500 million pounds of copper cathode per year from a 115,000-metric-ton-per-day crushed leach circuit and a ROM leaching operation. The available fleet consists of twenty-three 242-metric-ton haul trucks loaded by 4 electric shovels with buckets ranging in size from 29 to 41 cubic meters, which are capable of moving 217,000 metric tons of material per day. El Abra’s net PP&E and mine development costs at December 31, 2024, totaled $0.8 billion. El Abra’s copper production totaled 219 million pounds in 2024, 217 million pounds in 2023 and 202 million pounds in 2022. We have completed substantial drilling and evaluations to define a large sulfide resource that would support a potential major mill project similar to the large-scale concentrator at Cerro Verde. We are preparing data for a potential submission of an environmental impact statement by year-end 2025, subject to ongoing stakeholder engagement and economic evaluations. Preliminary estimates, which remain under review, indicate that the project economics would be supported using an incentive copper price of less than $4.00 per pound. The decision of whether to proceed and timing of the potential project will take into account overall copper market conditions, required permitting and other factors. El Abra is located in a desert environment with rainfall averaging less than one inch per year and is in an active seismic zone. The highest bench elevation is 4,225 meters above sea level and the ultimate pit bottom is expected to be 3,340 meters above sea level. El Abra controls a total of approximately 183,700 acres of mining claims covering the ore deposit, stockpiles, process plant, and water wellfield and pipeline. El Abra also has land surface rights for the road between the processing plant and the mine, the water wellfield, power transmission lines and for the water pipeline from the Salar de Ascotán aquifer. El Abra currently receives electrical power under a long-term contract with Engie Energía Chile S.A. Water for our El Abra processing operations currently comes from the continued pumping of groundwater from the Salar de Ascotán aquifer pursuant to regulatory approval. We believe El Abra has sufficient water sources to support current operations, although we are evaluating options for water infrastructure alternatives to provide options to extend existing operations and support a future expansion. Refer to “Governmental Regulations” above and Item 1A. “Risk Factors” for further discussion. 20 20 20 20 20 20 Table of Contents Table of Contents Table of Contents Indonesia Ownership. PT-FI is a limited liability company organized under the laws of the Republic of Indonesia. On December 21, 2018, we completed the transaction with the Indonesia government regarding PT-FI’s long-term mining rights and share ownership (the 2018 Transaction). Following the 2018 Transaction, we have a 48.76% share ownership in PT-FI and the remaining 51.24% share ownership is collectively held by PT Mineral Industri Indonesia (MIND ID), an Indonesia state-owned enterprise, and PT Indonesia Papua Metal Dan Mineral (formerly known as PT Indocopper Investama), which is expected to be owned by MIND ID and the provincial/regional government in Central Papua, Indonesia. IUPK. Concurrent with closing the 2018 Transaction, the Indonesia government granted PT-FI a special mining business license (IUPK) to replace its former contract of work. Under the terms of the IUPK, PT-FI has been granted an extension of mining rights through 2031, with rights to extend mining rights through 2041, subject to PT-FI completing the construction of additional domestic smelting and refining capacity in Indonesia and fulfilling its defined fiscal obligations to the Indonesia government. The IUPK, and related documentation, contains legal and fiscal terms and is legally enforceable through 2041. In addition, we, as a foreign investor, have rights to resolve investment disputes with the Indonesia government through international arbitration. Pursuant to regulations issued during 2024, PT-FI is eligible to apply for an extension of its mining rights beyond 2041, provided certain conditions are met, including ownership of integrated downstream facilities that have entered the operational stage; domestic ownership of at least 51% and agreement with a state-owned enterprise for an additional 10% ownership; and commitments for additional exploration and increases in refining capacity, each as approved by the Ministry of Energy and Mineral Resources. Application for extension may be submitted at any time up to one year prior to the expiration of the current IUPK. PT-FI expects to apply for an extension during 2025, pending agreement with MIND ID on a purchase and sale agreement for the transfer in 2041 of an additional 10% interest in PT-FI. An extension would enable continuity of large-scale operations for the benefit of all stakeholders and provide growth options through additional resource development opportunities in the highly attractive Grasberg minerals district. Refer to Item 1A. “Risk Factors” and Notes 10 and 11 for discussion of PT-FI’s IUPK, export licenses and risks associated with our Indonesia operations. Downstream Processing Facilities. In connection with the 2018 Transaction, PT-FI agreed to expand its domestic smelting and refining capacity. The new smelter and PT Smelting will smelt and refine copper concentrate from PT-FI, and the PMR will process anode slimes from the new smelter and PT Smelting. Once its new downstream processing facilities are operational, PT-FI’s operations will be fully integrated. 21 21 21 21 21 21 Table of Contents Table of Contents Table of Contents During 2024, construction of PT-FI’s new smelter in Eastern Java, Indonesia was completed. In October 2024, during start-up activities, a fire occurred that required a temporary suspension of smelting operations to complete repairs. Procurement of long-lead items is advanced and repairs are scheduled to be completed by mid-2025, and PT-FI expects ramp-up to full capacity to be achieved by year-end 2025. As part of start-up activities, PT-FI commenced gold production from its new PMR in December 2024. The PMR has the design capacity to refine all precious metals from PT-FI’s new smelter as well as from PT Smelting. Pursuant to the terms of its IUPK regarding force majeure events, PT-FI has requested approval from the Indonesia government to permit exports of copper concentrate in 2025 until the required repairs of its new smelter following the October 2024 fire incident and full ramp-up are complete. Based on discussions with the Indonesia government, PT-FI expects to re-commence exports of copper concentrate during first-quarter 2025, and pursuant to current regulations, would be required to pay a 7.5% export duty on all copper concentrate exports during 2025. Refer to “Smelting Facilities and Other Mining Properties” below, Item 1A. “Risk Factors,” MD&A and Notes 10 and 11 for additional discussion of PT-FI’s new downstream processing facilities. Grasberg Minerals District. PT-FI operates in the remote highlands of the Sudirman Mountain Range in the province of Central Papua, Indonesia, which is on the western half of the island of New Guinea. Since 1967, we and our predecessors have been the only operator of exploration and mining activities in the approximately 24,600-acre operating area.

The project area includes a 70-mile main service road from portsite to the mill complex. PT-FI’s net PP&E and mine development costs at December 31, 2024, including the new downstream processing facilities, totaled $21.1 billion. Production from the Grasberg minerals district totaled 1.8 billion pounds of copper and 1.9 million ounces of gold in 2024, 1.7 billion pounds of copper and 2.0 million ounces of gold in 2023, and 1.6 billion pounds of copper and 1.8 million ounces of gold in 2022. Over a multi-year investment period, PT-FI has successfully commissioned three large-scale underground mines in the Grasberg minerals district (Grasberg Block Cave, Deep Mill Level Zone (DMLZ) and Big Gossan). Milling rates for ore from these underground mines averaged 208,400 metric tons of ore per day in 2024, 198,300 metric tons of ore per day in 2023 and 192,600 metric tons of ore per day in 2022. Production from these underground mines is expected to continue through 2041 and an extension of PT-FI’s operating rights beyond 2041 would extend the lives of these mines. In December 2024, PT-FI completed construction of a new copper cleaner circuit, a mill recovery project to enhance recoveries and optimize concentrate production, with commissioning underway. Refer to Item 1A. “Risk Factors” for discussion of risks associated with development projects and underground mines. PT-FI plans to transition its existing energy source from coal to natural gas, which would meaningfully reduce PT-FI’s Scope 1 GHG emissions at the Grasberg minerals district. The majority of PT-FI’s planned investments in a new gas-fired combined cycle facility are expected to be incurred over the next three years, at a cost of approximately $1 billion, which represents an incremental cost of $0.4 billion compared to previously planned investments to refurbish the existing coal units. Once complete, PT-FI’s dual-fuel power plant and the new gas-fired combined cycle facility will be fueled by natural gas, supplied by a floating liquefied natural gas storage and regassification unit. A combination of naturally occurring mountain streams and water derived from our underground operations provides water for our operations. Our Indonesia operations are in an active seismic zone and experience average annual rainfall of approximately 200 inches. Grasberg Block Cave Underground Mine The Grasberg Block Cave ore body is the same ore body historically mined from the surface in the Grasberg open pit. Undercutting, drawbell construction and ore extraction activities in the Grasberg Block Cave underground mine continue to track expectations. As of December 31, 2024, the Grasberg Block Cave underground mine had 469 open drawbells. Ore milled from the Grasberg Block Cave underground mine averaged 133,800 metric tons per day in 2024, 117,300 metric tons per day in 2023 and 103,300 metric tons per day in 2022. 22 22 22 22 22 22 Table of Contents Table of Contents Table of Contents The Grasberg Block Cave fleet consists of approximately 530 pieces of mobile equipment.

Lower production volumes in 2025, compared to 2024 and 2023, reflect the timing of the September 2025 mud rush incident at PTFI. PT Smelting’s major scheduled maintenance turnarounds (which approximate 30 days to complete) are expected to occur every two years, with short-term maintenance turnarounds in the interim. In July 2023, PT Smelting completed a 72-day shutdown associated with its expansion project and in November 2023, a 7-day shutdown to complete final tie-in of the expansion project. In July 2025, PT Smelting completed a 30-day planned major maintenance turnaround. However, operational challenges with a third-party oxygen plant caused a delay in the restart of operations until September 2025. Atlantic Copper. Our wholly owned Atlantic Copper smelter and refinery is located on land concessions from the Huelva, Spain, port authorities, which are scheduled to expire in 2038. The smelter has a design capacity to produce approximately 300,000 metric tons of copper per year, and the refinery has a capacity to produce 286,000 metric tons of copper per year. Atlantic Copper’s copper anode production from its smelter totaled 249,300 metric tons in 2025, 247,600 metric tons in 2024 and 261,900 metric tons in 2023. Copper cathode production from its refinery totaled 249,600 metric tons in 2025, 254,400 metric tons in 2024 and 260,300 metric tons in 2023. During 2025, Atlantic Copper purchased 77% of its copper concentrate from third parties, 21% from our South America operations and 2% from our U.S. copper mines. Atlantic Copper’s major maintenance turnarounds typically occur approximately every eight years, with shorter-term maintenance turnarounds in the interim. In 2024, Atlantic Copper completed a 17-day maintenance turnaround. Atlantic Copper is developing an e-material recycling project as a result of the significant and continued growth in electronic waste material. Atlantic Copper’s existing smelting and refining facilities provide synergies to recycle this type of material. The project, which is expected to commence operations in 2026, would include an addition of a smelting furnace and associated equipment to recover copper, gold, silver, palladium, tin, nickel and platinum from electronic materials. Atlantic Copper estimates that the initial project capital will approximate $560 million. Miami Smelter. We own and operate a smelter at our Miami mining operation in Arizona. The smelter has been operating for more than 100 years and has been upgraded numerous times during that period to implement new technologies, improve production and comply with air quality requirements. The Miami smelter processes copper concentrate primarily from our U.S. copper mines. Concentrate processed through the smelter totaled 821,200 metric tons in 2025, 840,600 metric tons in 2024 and 810,900 metric tons in 2023, and copper anode production from the smelter totaled 209,300 metric tons in 2025, 214,000 metric tons in 2024 and 222,000 metric tons in 2023. In addition, because sulfuric acid is a by-product of smelting concentrate, the Miami smelter is also the most significant source of sulfuric acid for our U.S. leaching operations. Major maintenance turnarounds are anticipated to occur approximately every three to four years for the Miami smelter. In 2025, the Miami smelter performed a major maintenance turnaround and incurred maintenance charges and idle facility costs totaling $73 million. U.S. Rod & Refining Operations. Our U.S. Rod & Refining operations consist of conversion facilities that include a refinery in El Paso, Texas, and rod mills in El Paso, Texas and Miami, Arizona. We refine our copper anode production from our Miami smelter at our El Paso refinery. Our El Paso refinery also produces nickel carbonate, copper telluride and autoclaved slimes material containing gold, silver, platinum and palladium. 27 27 27 27 27 27 Table of Contents Table of Contents Table of Contents The El Paso refinery has the potential to operate at an annual production capacity of approximately 410,000 metric tons of copper cathode, which is sufficient to refine all of the copper anode we produce at our Miami smelter. Copper cathode production from the El Paso refinery totaled 204,900 metric tons in 2025, 221,300 metric tons in 2024 and 217,800 metric tons in 2023. We manufacture continuous cast copper rod at our U.S. rod facilities primarily using copper produced at our U.S. copper mines and processing facilities. Rod production from these facilities approximated one billion pounds for each of the last three years. Molybdenum Conversion Facilities. We process molybdenum concentrate at our conversion plants in the U.S. and Europe into such products as technical-grade molybdic oxide, ferromolybdenum, pure molybdic oxide, ammonium molybdates and molybdenum disulfide. We operate molybdenum roasters in Sierrita, Arizona; Fort Madison, Iowa; and Rotterdam, the Netherlands, and we operate a molybdenum pressure-leach plant in Bagdad, Arizona. We also produce ferromolybdenum for customers worldwide at our conversion plant located in Stowmarket, United Kingdom. Other U.S. Copper Mines. We have five non-operating copper mines – Ajo, Bisbee, Tohono, Twin Buttes and Christmas, which are located in Arizona – that have been on care and maintenance status for several years and would require new or updated environmental studies, new permits, and additional capital investment, which could be significant, to return them to operating status.",
      "prior_body": "PT-FI’s New Downstream Processing Facilities. PT-FI’s new smelter and PT Smelting (see further discussion below) will smelt and refine copper concentrate from PT-FI, and the PMR will process anode slimes from the new smelter and PT Smelting. Once its new downstream processing facilities are operational, PT-FI’s operations will be fully integrated. PT-FI’s new greenfield smelter in Eastern Java, Indonesia has a capacity to process approximately 1.7 million metric tons of copper concentrate per year. During start-up activities, a fire occurred in October 2024, requiring a temporary suspension of smelting operations to complete repairs. Procurement of long-lead items is advanced and repairs are scheduled to be completed by mid-2025. PT-FI expects restoration, repair and replacement costs to approximate $100 million, which are expected to be mostly offset through recovery under construction insurance programs. PT-FI expects ramp-up to full capacity to be achieved by year-end 2025. As part of start-up activities, PT-FI commenced gold production from its new PMR in December 2024. PT Smelting. PT Smelting, an Indonesian joint venture between PT-FI and MMC, owns a copper smelter and refinery in Gresik, Indonesia. In December 2023, PT Smelting completed the expansion of its capacity by 30% to process approximately 1.3 million metric tons of copper concentrate per year. The project was funded by PT-FI with loans totaling $254 million that converted to equity effective June 30, 2024, increasing PT-FI’s ownership in PT Smelting to 66% from 39.5%. As discussed in Note 2, PT-FI continues to account for its investment in PT Smelting under the equity method. Beginning in 2023, PT-FI’s commercial arrangement with PT Smelting changed from a copper concentrate sales agreement to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee (which PT-FI records as production costs in the consolidated statements of income) to smelt and refine its copper concentrate and PT-FI retains title to all products for sale to unaffiliated third parties (i.e., there are no further sales to PT Smelting).

Concentrate processed through the smelter totaled 840,600 metric tons in 2024, 810,900 metric tons in 2023 and 781,000 metric tons in 2022, and copper anode production from the smelter totaled 214,000 metric tons in 2024, 222,000 metric tons in 2023 and 202,000 metric tons in 2022. In addition, because sulfuric acid is a by-product of smelting concentrate, the Miami smelter is also the most significant source of sulfuric acid for our North America leaching operations. Major maintenance turnarounds are anticipated to occur approximately every three to four years for the Miami smelter. We performed a major maintenance turnaround during 2021 and the next major maintenance turnaround is scheduled for mid-year 2025, for which we expect to incur maintenance charges and idle facility costs of approximately $85 million. Rod & Refining Operations. Our Rod & Refining operations consist of conversion facilities located in North America, including a refinery in El Paso, Texas, and rod mills in El Paso, Texas and Miami, Arizona. We refine our copper anode production from our Miami smelter at our El Paso refinery. The El Paso refinery has the potential to operate at an annual production capacity of approximately 410,000 metric tons of copper cathode, which is sufficient to refine all of the copper anode we produce at our Miami smelter. Copper cathode production from the El Paso refinery totaled 221,300 metric tons in 2024, 217,800 metric tons in 2023 and 208,900 metric tons in 2022. Our El Paso refinery also produces nickel carbonate, copper telluride and autoclaved slimes material containing gold, silver, platinum and palladium. Molybdenum Conversion Facilities. We process molybdenum concentrate at our conversion plants in the U.S. and Europe into such products as technical-grade molybdic oxide, ferromolybdenum, pure molybdic oxide, ammonium molybdates and molybdenum disulfide. We operate molybdenum roasters in Sierrita, Arizona; Fort Madison, Iowa; and Rotterdam, the Netherlands, and we operate a molybdenum pressure-leach plant in Bagdad, Arizona. We also produce ferromolybdenum for customers worldwide at our conversion plant located in Stowmarket, United Kingdom. Other North America Copper Mines. We have five non-operating copper mines – Ajo, Bisbee, Tohono, Twin Buttes and Christmas, which are located in Arizona – that have been on care and maintenance status for several years and would require new or updated environmental studies, new permits, and additional capital investment, which could be significant, to return them to operating status."

      "current_body": "Indonesia. Indonesia has long faced separatist movements and civil and religious strife in a number of provinces. Several separatist groups have sought increased political independence for the western half of the island of New Guinea, which includes the province of Central Papua, where our Grasberg minerals district is located. In Central Papua, there have been attacks on civilians by separatists and conflicts between separatists and the Indonesia military and police. In addition, illegal miners have clashed with police who have attempted to move them away from our facilities. Social, economic and political instability in Central Papua could materially adversely affect us if it results in damage to our property or interruption of our Indonesia operations. Shootings and other violent incidents have occurred within the PTFI project area and support areas, including along the road leading to our mining and milling operations, which in some instances have involved fatalities or injuries to our employees, contractors, government security personnel and civilians. The most recent incidents associated with the PTFI operations occurred in early 2026, and prior to that in 2021. In the most recent incident, a PTFI contractor was injured, along with two accompanying Indonesian military personnel, one of whom was fatally injured. In 2025, based on publicly available reports, we believe that there were more than 55 incidents of separatist violence, resulting in approximately 79 fatalities outside of the PTFI project area and support areas at the Grasberg minerals district unrelated to PTFI’s operations but within the province of Central Papua. Separatist security incidents, including shootings, attacks on civil infrastructure and arson, continue to occur in Central Papua and other areas near the PTFI project area. PTFI actively monitors security conditions and the occurrence of incidents both regionally and within the project and support areas. The safety of our workforce is a critical concern, and PTFI continues to work with the Indonesia government to enhance security and address security-related issues within the PTFI project area and in support areas, as well as at PTFI’s downstream processing facilities. Although we have implemented measures and safeguards consistent with both international standards and our own internal standards relating to the use of force and respect for human rights, the implementation of these measures and safeguards does not guarantee that personnel, national police or other security forces will uphold these standards in every instance. We are exposed to security risks relating to loss and theft of refined precious metals at the PMR. Any such loss or theft could lead to financial loss or a failure to satisfy our customer commitments, which could have an adverse impact on our reputation and business. We cannot predict whether additional incidents will occur that could result in loss of life, or disruption or suspension of PTFI’s operations. If other disruptive incidents occur, they could adversely affect our results of operations and financial condition. South America. South America countries have historically experienced periods of economic growth, as well as recession, periods of high inflation and general socio-economic and political instability. In Peru, political uncertainty has created instability in the regulatory environment. Beginning in December 2022 and continuing in 2023, heightened tensions, protests and social unrest emerged in Peru following a change in the country’s political leadership, which temporarily resulted in delays in the transport of supplies, products and people at our Cerro Verde mine. During first-quarter 2023, Cerro Verde also operated at reduced rates from time to time until it resumed normal operations in March 2023. Other mining operations in the region temporarily halted mining activities as a result of the civil unrest. While demonstrations and road blockages subsided in 2023, the political situation in Peru remains complex, with its president being impeached in October 2025. In addition, the potential for civil unrest, including in relation to mining operations, and disruption of commerce and supply chains continues. Other operations in the region have encountered significant issues with trespassers, illegal miners and civil demonstrations that impact their operations, expansion projects, logistical supply and product transport. Such protests have occasionally been accompanied by acts of violence and property damage and continue intermittently in the region. In Chile, despite the overwhelming electoral approval of a proposal to rewrite the constitution in a 2020 referendum, the product of the constitutional assembly was rejected by a majority of voters in 2022 and 2023. The political 63 63 63 63 63 63 Table of Contents Table of Contents Table of Contents environment remains polarized following the national legislative elections, including the presidential election, held in Chile during 2025.

Further, we have significant net operating losses (NOLs) in the U.S. generated in prior years, which we believe are available to offset future regular taxable income. However, changes in tax laws and regulations or interpretations of such laws and regulations may result in new limitations on our ability to benefit from our significant U.S. NOLs.

The provisions of the U.S. Inflation Reduction Act of 2022 (the Act), which became applicable to us on January 1, 2023, include, among other provisions, a new Corporate Alternative Minimum Tax (CAMT) of 15% on the adjusted 54 54 54 54 54 54 Table of Contents Table of Contents Table of Contents financial statement income of certain corporations. As discussed in Note 9, based on current guidance, we have determined that the provisions of the Act did not impact our financial results for the three years ended December 31, 2025, but the proposed and interim guidance released by the Internal Revenue Service relating to the calculation of the CAMT is not final and is subject to change. Additionally, on July 4, 2025, the President signed into law H.R.1 (also referred to as the One Big Beautiful Bill Act), which includes a broad range of tax reform provisions affecting businesses, including extending and modifying certain provisions of the Tax Cuts & Jobs Act of 2017. H.R.1 did not have a material impact on our consolidated financial results for the year 2025. The aggregate impact of H.R.1, including how it will be interpreted and applied to us, remains uncertain. In December 2021, the Organisation for Economic Co-operation and Development (OECD) published a framework for Pillar Two of the Global Anti-Base Erosion Rules, which was designed to coordinate participating jurisdictions in updating the international tax system to ensure that large multinational companies pay a 15% minimum level of income tax. In January 2026, the OECD published additional guidance on the framework, including safe harbor provisions that would minimize or eliminate application of the 15% global minimum income tax on domestic operations of U.S.-parent multinational companies. Recommendations from the OECD regarding the 15% global minimum income tax, the safe harbor provisions and other changes are being considered and/or implemented in jurisdictions where we operate. The adoption and effective dates for such tax changes may vary by jurisdiction, could increase tax complexity and uncertainty, and may adversely affect our provision for income taxes. At current metals market prices, we do not expect enactment of the recommended framework in jurisdictions where we operate to materially impact our financial results for 2026. However, additional changes to these tax laws and regulations, including as a result of new guidance and interpretations, may occur and such changes could adversely affect our tax liability.",

In December 2021, the Organisation for Economic Co-operation and Development (OECD) published a framework for Pillar Two of the Global Anti-Base Erosion Rules, which was designed to coordinate participating jurisdictions in updating the international tax system to ensure that large multinational companies pay a minimum level of income tax. Recommendations from the OECD regarding a global minimum income tax and other changes are being considered and/or implemented in jurisdictions where we operate. At current metals market prices, we do not expect enactment of the recommended framework in jurisdictions where we operate to materially impact our financial results."

We have several projects and potential opportunities to expand production volumes, extend mine lives and develop large-scale underground ore bodies. As further discussed in MD&A, our near-term major development projects will focus on the underground development activities in the Grasberg minerals district as well discretionary growth projects for the development of Kucing Liar and at the Bagdad mine. Considering the long-term nature and large size of our development projects, actual costs and timing could vary from estimates. We continue to review our mine development and processing plans to maximize the value of our mineral reserves. Specifically, we are carefully managing operating costs and near-term capital expenditures in connection with revised operating plans at the Grasberg minerals district to manage cash flow and liquidity during the phased ramp-up period after the September 2025 mud rush incident. Based on the current reserve life through 2041, full development of PTFI’s underground mineral reserves at the Grasberg minerals district is expected to require approximately $1 billion (most of which is expected to be incurred over the next 5 years) of capital expenditures primarily associated with its processing facilities to optimize the handling of underground ore from the Grasberg Block Cave, DMLZ and Kucing Liar deposits. This estimate incorporates a $3 billion reduction in previously expected capital expenditures associated with the processing of higher pyrite ore resulting from mine plan changes related to the expansion of the Kucing Liar to 130,000 metric tons of ore per day. Increases in power loads at these processing facilities and the underground mines are expected to require additional power generation and as such, PTFI is planning investments in a new gas-fired combined cycle facility. PTFI’s dual-fuel power plant and the new gas-fired combined cycle facility are expected to be fueled by natural gas, supplied by a floating LNG storage and regassification unit. Refer to “Operations – Indonesia” above for further discussion. In 2025, exploration spending associated with our mining operations totaled $143 million. Our mining exploration activities are primarily associated with our existing mines, focusing on opportunities to expand mineral reserves and resources to support development of additional future production capacity. Exploration results continue to indicate opportunities for significant future potential reserve additions at our existing properties. Additionally, in connection with a long-term extension of PTFI’s mining rights beyond 2041, PTFI would pursue additional exploration and conduct studies for future additional development.

Partially because of the Grasberg minerals district’s significance to Indonesia’s economy (including the downstream operations), the environmentally sensitive area where it is located, and the number of local people employed, our Indonesia operations have been the subject of political debates and criticism in the Indonesia press and have been the target of protests and occasional violence. Improper management of our working relationship with the Indonesia government, MIND ID or the local population could lead to a disruption of operations and/or impact our reputation in Indonesia and in the region where we operate, which could adversely affect our business. 56 56 56 56 56 56 Table of Contents Table of Contents Table of Contents The mining industry is subject to extensive regulation within Indonesia, and there have been major developments in laws and regulations applicable to mining concession holders, some of which have conflicted with PTFI’s contractual rights and may conflict with PTFI’s contractual rights in the future. For example, in 2009, the Indonesia government enacted a mining law that sought to modify PTFI’s former contract of work, certain provisions of which were not required under or conflicted with PTFI’s former contract of work. In December 2018, PTFI was granted an IUPK to replace its former contract of work, enabling PTFI to conduct operations in the Grasberg minerals district through 2041, subject to certain requirements. Refer to Note 11 for a summary of the IUPK’s key fiscal terms and requirement to develop additional smelting and refining capacity. Pursuant to regulations issued during 2024, PTFI is eligible to apply for an extension of its mining rights beyond 2041, provided certain conditions are met. Refer to Note 10 for a summary of such conditions and the risk factor below relating to potential extension. Since 2019, the Indonesia government has enacted various laws and regulations related to downstream processing of various products. Refer to “Operations – Indonesia” in MD&A and Notes 10 and 11 for a discussion of Indonesia regulatory matters, including those related to export licenses, export duties, export proceeds, smelter assurance bonds and PTFI’s new smelter and precious metals refinery (PMR) (collectively, PTFI’s downstream processing facilities) in Eastern Java, Indonesia. With the completion of its downstream processing facilities, PTFI is a fully integrated producer of refined copper and gold. Following the September 2025 mud rush incident, smelting operations in Indonesia at both PTFI’s smelter and PT Smelting were temporarily suspended during fourth-quarter 2025 as a result of limited copper concentrate availability. PT Smelting restarted operations in late December 2025 and is expected to operate at reduced rates pending the anticipated second-quarter 2026 restart of mining at the Grasberg Block Cave underground mine. Shipments to PTFI’s smelter are expected to recommence in the second half of 2026, pending the successful ramp up of mining operations. We expect higher variability between PTFI’s production and sales until its downstream processing facilities achieve normalized operating rates. Following the expiration of its export license on September 16, 2025, PTFI expects all of its concentrate to be processed by its downstream processing facilities and does not have export licenses for copper concentrate or anode slimes. As such, if the downstream processing facilities are not operational when copper concentrate is available, PTFI could be required to reduce production levels or be subject to increased costs, which could adversely impact our revenues and operations. Political considerations and administrative changes resulting from elections, including Indonesia’s most recent national legislative and presidential elections held in 2024 and future elections, could affect, among other things, national and local policies pertaining to foreign investment, permitting and export restrictions, which could adversely affect our Indonesia operations. In 2023, the Indonesia government issued a regulation that required 30% of PTFI’s gross export proceeds to be temporarily deposited into Indonesia banks for a period of 90 days before withdrawal. Effective March 1, 2025, the Indonesia government implemented a new regulation (March 2025 Regulation) for export proceeds that requires 100% of PTFI’s export proceeds to be deposited into Indonesia banks for 12 months. The March 2025 Regulation allows the use of funds for ongoing business requirements, including dividends to shareholders, payment of taxes and other obligations to the Indonesia government, payment for materials or capital expenditures that are not available domestically and repayment of loans. The Indonesia government is considering additional changes to the March 2025 Regulation; however, the details of the modifications have not been finalized. Refer to Note 10 for further discussion of the March 2025 Regulation. There can be no assurance that future regulatory changes affecting the mining industry in Indonesia will not be introduced or unexpectedly repealed, or that new interpretations of existing laws and regulations will not be issued, any of which may conflict with PTFI’s contractual rights, which could adversely affect our business, financial condition and results of operations. 57 57 57 57 57 57 Table of Contents Table of Contents Table of Contents",

PT-FI expects to apply for an extension during 2025, pending agreement with MIND ID on a purchase and sale agreement for the transfer in 2041 of an additional 10% interest in PT-FI. We cannot guarantee that PT-FI will receive an extension of mining rights beyond 2041.

In October 2024, a fire occurred during commissioning of PT-FI’s new smelter in Eastern Java, Indonesia, requiring a temporary suspension of smelting operations to complete repairs. Procurement of long-lead items is advanced, and repairs are scheduled to be completed by mid-2025. Current regulations in Indonesia prohibit exports of copper concentrate as of January 1, 2025. Pursuant to the terms of its IUPK regarding force majeure events, PT-FI has requested approval from the Indonesia government to permit the export of copper concentrates in 2025 until the required repairs of its new smelter following the October 2024 fire incident and full ramp-up are complete. Based on discussions with the Indonesia government, PT-FI expects to re-commence exports of copper concentrate during first-quarter 2025, and pursuant to current regulations, would be required to pay a 7.5% export duty on all copper concentrate exports during 2025. If PT-FI does not receive a timely export license or if any limitations on exports or additional export duties resulting from Indonesia regulations were to be implemented prior to PT-FI’s new downstream processing facilities becoming operational, PT-FI could be required to reduce production levels or be subject to increased costs, which could adversely impact our revenues and operations. There can be no assurance that future regulatory changes affecting the mining industry in Indonesia will not be introduced or unexpectedly repealed, or that new interpretations of existing laws and regulations will not be issued, any of which may conflict with PT-FI’s contractual rights, which could adversely affect our business, financial condition and results of operations. Beginning in 2022, the Indonesia government divided the Indonesia portion of the island of New Guinea from two provinces into a total of six provinces, which has resulted in public protest and civil unrest. For further discussion of violence, civil and religious strife, and activism affecting our operations in Indonesia, see the related risk factor below. Further, we cannot predict the impact of splitting provinces on local and regional regulations, permits and other governmental administrative functions, which could have an adverse impact on our business. In 2024, Indonesia held national legislative elections, including the presidential election. Political considerations and administrative changes resulting from these elections or future elections could affect, among other things, national and local policies pertaining to foreign investment, permitting and export restrictions, which could adversely affect our Indonesia operations. In accordance with a regulation issued by the Indonesia government in 2023, 30% of PT-FI’s gross export proceeds are being temporarily deposited into Indonesia banks for a period of 90 days before withdrawal. The Indonesia government is considering changes to this regulation, which could increase the amount and length of the requirement, but also allow withdrawals from the balances to fund business requirements. The details of the modifications have not been finalized."

With the completion of PTFI’s downstream processing facilities during 2025, FCX and PTFI have advanced discussions with the Indonesia government for a long-term extension of PTFI’s operating rights beyond the current expiration in 2041. PTFI is preparing its application for a long-term extension expected to cover the life of the resource, which is expected to be submitted during 2026. In connection with the extension, PTFI would pursue additional exploration, conduct studies for future additional development and expand its social programs. FCX expects to maintain its ownership interest in PTFI of approximately 49% through 2041 and hold approximately 37% beginning in 2042, following the transfer of an additional interest in PTFI to an Indonesia state-owned enterprise. FCX expects the existing governance agreements would continue over the life of the resource. We cannot guarantee that PTFI will receive an extension of mining rights beyond 2041 or that such extension will be on the terms expected.",
      "prior_body": "Under the terms of PT-FI’s IUPK, PT-FI has been granted mining rights through 2031, with rights to extend its mining rights through 2041, subject to certain terms and conditions. Refer to Note 11 for a summary of the IUPK’s key fiscal terms. Our proven and probable mineral reserves in Indonesia reflect estimates of minerals that can be recovered through the end of 2041, and PT-FI’s current long-term mine plan and planned operations are based on the assumption that PT-FI will abide by the terms and conditions of the IUPK and will be granted the 10-year extension from 2031 through 2041. As a result, PT-FI will not mine all of these mineral reserves during the initial term of the IUPK. Prior to the end of 2031, we expect to mine 40% of aggregate proven and probable recoverable mineral reserves at December 31, 2024, representing 45% of FCX’s net equity share of recoverable copper reserves in Indonesia and 44% of FCX’s net equity share of recoverable gold reserves in Indonesia. If PT-FI does not achieve full ramp-up at the new downstream processing facilities, or fulfill its defined fiscal obligations to the Indonesia government as set forth in the IUPK, the IUPK may not be extended from 2031 through 2041, and PT-FI would be unable to mine all of its proven and probable mineral reserves in the Grasberg minerals district, which could adversely affect our business, results of operations and financial position. 55 55 55 55 55 55 Table of Contents Table of Contents Table of Contents PT-FI and the Indonesia government continue to engage in discussions regarding the extension of PT-FI’s IUPK beyond 2041. While PT-FI expects to apply for an extension during 2025, pending agreement with MIND ID on a purchase and sale agreement for the transfer in 2041 of an additional 10% interest in PT-FI, we cannot predict whether the application will be successful in extending PT-FI’s IUPK beyond 2041."

These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors other than the candidates nominated by the Board. Refer to Exhibit 4.1 for further discussion of our anti-takeover provisions. Further, our By-Laws provide to the fullest extent permitted by law that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, the U.S. District Court for the District of Delaware) will be the sole and exclusive forum for any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim that is based upon a violation of a duty by any of our current or former directors, officers, employees or stockholders in such capacity, (iii) action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (DGCL) or to which the DGCL confers jurisdiction upon the Court of Chancery of the State of Delaware, (iv) action asserting a claim governed by the internal affairs doctrine, or (v) action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL.

We are also involved periodically in other reviews, inquiries, investigations and proceedings initiated by or involving government agencies, some of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. For example, we have been cooperating with and responding to a subpoena from the U.S. Securities and Exchange Commission (SEC) and an information request from the U.S. Department of Justice (DOJ) related to our public disclosures about the engineering design and construction of PTFI’s smelter in Indonesia, which is also the subject matter in a separate whistleblower complaint from a former contractor that we are defending before the U.S. Department of Labor. We cannot predict the outcome of these investigations, and the outcome of any legal proceeding is inherently uncertain and adverse developments or outcomes could result in significant monetary damages, penalties, other sanctions or injunctive relief against us, limitations on our property rights, or regulatory interpretations that increase our operating costs, some of which may not be covered by insurance. Further, to the extent that societal pressures or political or other factors are involved, it is possible that liability could be imposed without regard to our causation of or contribution to the asserted damage, or to other mitigating factors. Management does not believe, based on currently available information, that the outcome of any individual legal proceeding currently pending will have a material adverse effect on our financial condition, although individual or cumulative outcomes could be material to our operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period. Regardless of the merit of particular claims, defending against legal proceedings or responding to investigations can be expensive, time-consuming, disruptive to our operations and distracting to management. In recognition of these considerations, we may enter into agreements or other arrangements to settle legal proceedings and resolve such challenges. There can be no assurance such agreements can be obtained on acceptable terms or that legal proceedings will not occur. From time to time, we are involved in disputes over the allocation of environmental response costs and obligations at “Superfund” and other sites. We may be held responsible for the costs of addressing contamination at the site of current or former activities or at third-party sites or be held liable to third parties for exposure to hazardous substances should those be identified in the future. For further discussion of our environmental obligations, see the regulatory, environmental and social risks below. Further, we are a global business with operations in various jurisdictions. In the event of a dispute arising at our foreign operations, we may be subject to the exclusive jurisdiction of foreign courts or arbitral panels, or may not be successful in subjecting foreign persons to the jurisdiction of courts or arbitral panels in the U.S. or in enforcing the judgment of a foreign court or arbitral panel against a sovereign nation. Our inability to enforce our rights and the enforcement of rights on a prejudicial basis by foreign courts or arbitral panels, including against a sovereign nation, could have an adverse effect on our results of operations and financial position."

      "current_body": "Our estimates of mineral reserves and mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of SEC Regulation S-K. There are numerous uncertainties inherent in mineral estimates. Such estimates are, to a large extent, based on assumed long-term prices for the commodities we produce, primarily copper, gold and molybdenum, and interpretations of geologic data obtained from drill holes and other exploration techniques, which may not necessarily be indicative of future results. Our mineral estimates are based on the latest available geological and geotechnical studies. We conduct ongoing studies of our ore bodies to evaluate economic values and to manage risk. We revise our mine plans and estimates of recoverable proven and probable mineral reserves as required in accordance with the latest available studies. Geological assumptions about our mineral resources that are valid at the time of estimation may change significantly when new information becomes available. Estimates of mineral reserves, or the cost at which we anticipate the mineral reserves will be recovered, are based on assumptions, such as metal prices and other economic inputs. Changes to such assumptions may require revisions to mineral reserve estimates which could affect our asset carrying values and may also negatively impact our future financial condition and results. Until mineral reserves are actually mined and processed, the quantity of ore and grades must be considered as an estimate only. In addition, if the market prices for the commodities we produce decline from assumed levels, if production costs increase or recovery rates decrease, or if applicable laws and regulations are adversely changed, there can be no assurance that the indicated level of recovery will be realized or that mineral reserves can be mined or processed profitably. If we determine that certain of our estimated recoverable proven and probable mineral reserves have become uneconomic, this may ultimately lead to a reduction in our aggregate reported mineral reserves, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, the term “mineral resources” does not indicate recoverable proven and probable mineral reserves as defined by the SEC. Estimates of mineral resources are subject to further exploration and evaluation of development and operating costs, grades, recoveries and other material factors, and, therefore, are subject to considerable uncertainty. Mineral resources do not meet the threshold for mineral reserve modifying factors, such as engineering, legal and/or economic feasibility, that would allow for the conversion to mineral reserves. Accordingly, there can be no assurance that the estimated mineral resources not included in mineral reserves will become recoverable proven and probable mineral reserves. 68 68 68 68 68 68 Table of Contents Table of Contents Table of Contents"

For further discussion regarding recent macroeconomic and geopolitical factors, see the risk factor below regarding the price and availability of consumables and components we purchase and constraints on supply and logistics, and transportation services. There has been a history of significant volatility in the commodities markets, including the copper market. Fluctuations in commodities prices are caused by varied and complex factors beyond our control, including global supply and demand impacted by industry production and inventory levels; global economic and political conditions (such as election results, level of economic growth, or recession and political or geopolitical tensions and conflicts); national and international regulatory, trade and/or tax policies, including tariffs and other controls or restrictions on imports and exports; commodities investment activity and speculation; interest rates; current inflation rates and expectations regarding future inflation rates; the strength of the U.S. dollar compared to foreign currencies; the price and availability of substitute products; and changes in technology. Volatility in global economic growth, particularly in developing economies, has the potential to affect adversely future demand and prices for commodities. Geopolitical uncertainty and protectionism can inhibit international trade and negatively impact business confidence, which creates the risk of constraints on our ability to deal in certain markets and has the potential to increase price volatility. For further discussion regarding the historical fluctuations of the prices of copper, gold and molybdenum, refer to “Markets” in MD&A. In addition to the factors discussed above, copper prices may be affected by demand from China, which is currently the largest consumer of refined copper in the world, including as a result of geopolitical uncertainty and tension between the U.S. and China as well as uncertainties about China’s economy. Copper demand and prices also may be affected by industry production, substitution and thrifting. The adoption and expansion of trade restrictions, or other governmental action related to tariffs and other controls on imports and exports or trade agreements or policies are difficult to predict and could adversely affect copper prices, demand for our products, our costs, our customers, our suppliers and the global economy, which in turn could have a material adverse effect on our business, results of operations or financial condition. For further discussion, refer to “Markets” and “U.S. Tariffs” in MD&A. We believe long-term fundamentals for copper are favorable with growing demand supported by copper’s critical role in the global transition to renewable power, electric vehicles and other carbon-reduction initiatives, continued urbanization in developing countries, data centers and artificial intelligence (AI) developments and growing connectivity globally; however if these markets, industries and transitions do not develop as we expect, or develop more slowly than we expect, future demand and prices for copper may be negatively affected, impacting our business. Copper demand and prices also may be affected by inadequate investment in and limited production from existing copper mining operations (including due to limited or suspended operations), and copper demand globally, including the U.S., Europe and Asian countries other than China. Additional factors affecting gold prices may include purchases and sales of gold by governments and central banks, demand from China and India (two of the world’s largest consumers of gold), and global demand for jewelry containing gold. If market prices for the primary commodities we produce were to decline and remain low for a sustained period of time, we may have to revise our operating plans, including curtailing or modifying our mining and processing operations, as we have done in the past, and our cash flows, ability to return capital to shareholders and capital expenditure plans could be negatively affected. We may be unable to decrease our costs in an amount sufficient to offset reductions in revenues, in which case we may incur losses, and those losses may be material. Declines in prices of commodities we sell could also result in metals inventory adjustments and impairment charges for our long-lived assets."

We are required to comply with a wide range of laws and regulations in the countries where we operate or do business. For example, our international operations must comply with the U.S. Foreign Corrupt Practices Act (FCPA) and similar anti-corruption and anti-bribery laws of the other jurisdictions in which we operate. We are investigating whether activities of PT Smelting may have violated aspects of the FCPA or other laws, including laws of non-U.S. jurisdictions. PT Smelting is an Indonesian joint venture between PTFI and Mitsubishi Materials Corporation (MMC), and an affiliate of MMC serves as operator of PT Smelting (see Note 2). As previously reported, we voluntarily notified the SEC and DOJ that we engaged outside counsel to conduct the investigation of PT Smelting’s activities. Any determination that operations or activities are not in compliance with existing laws, including the FCPA, could result in the imposition of fines, penalties and equitable remedies. We cannot currently predict the outcome of our investigation. We operate in jurisdictions that have experienced public and private sector corruption and where significant anti-corruption enforcement activities, prosecutions and settlements have occurred. We have a large number of contracts with local and foreign business partners, including suppliers and contractors, who may take action contrary to or fail to adopt standards, controls and procedures, including health, safety, environmental, human rights and community standards that are equivalent to our standards, controls and procedures. There can be no assurance that our policies, procedures and internal controls will protect us from misinterpretation of or noncompliance with applicable laws and internal policies, recklessness, fraudulent behavior, dishonesty or other inappropriate acts committed by our affiliates, employees, contractors or other business partners. As such, our policies, procedures and internal controls may not prevent or detect all potential breaches of law or governance practices. Any breaches could result in safety events that may result in injuries or fatalities; significant criminal or civil fines, penalties, litigation or regulatory action or inquiries or other enforcement actions; shareholder or other stakeholder activism (such as to stop using a certain business partner); civil unrest or other adverse impacts on human rights; termination of contracts; loss of operating licenses or permits; and damage to our reputation, any of which could have a material adverse effect on our cash flows, results of operations and financial condition. In addition, our insurance does not cover most losses caused by the risks described above. For example, we do not maintain political risk insurance. We conduct international operations and exploration activities in Indonesia, Peru and Chile as well as other foreign jurisdictions.

Managing the volume of waste rock and tailings presents significant environmental, safety and engineering challenges and risks primarily relating to structural stability, geochemistry, water quality and dust generation. Management of this waste is regulated in the jurisdictions where we operate and our programs are designed to comply with applicable national, state and local laws, permits and approved environmental impact studies. We maintain large stockpiles and tailings impoundments. Our leaching innovation initiatives include measures that are intended to enhance solution flow through our leach stockpiles, which may increase risks for solution spills or physical instability of such stockpiles. Tailings impoundments include large embankments that must be engineered, constructed and monitored to ensure structural stability and avoid structural collapse. Our tailings impoundments in arid areas must have effective programs to suppress fugitive dust emissions to meet regulatory requirements, which vary depending on location, and to limit potential impacts of dust emissions from our operations on surrounding communities and the environment. Additionally, we must effectively monitor, prevent and treat acid rock drainage at all of our operations. In Indonesia, we use a controlled riverine tailings management system, which presents other risks discussed in more detail in the risk factor below relating to the environmental challenges at our Indonesia mining operations. As of December 31, 2025, we operated 15 active tailings storage facilities (13 in the U.S. and 2 in Peru), of which 10 have an upstream design and 5 have a centerline design. Additionally, we have one centerline tailing storage facility in development. We also manage 9 tailings storage facilities in the U.S. that are inactive or closed (8 with an upstream design, and 1 with a centerline design) and another 45 that are deemed “safely closed” according to the definition in the Tailings Standard. In 2025, we produced approximately 326 million metric tons of tailings globally. The failure of tailings storage facilities, other embankments or stockpiles at any of our mining operations could cause severe, and in some cases catastrophic, property and environmental damage and loss of life, as well as adverse effects on our business and reputation. Some of our tailings storage facilities are located in areas where a failure has the potential to impact individual dwellings, and at least one of our impoundments is in an area where a failure has the potential to impact nearby communities or mining infrastructure. There can be no assurance that a severe or catastrophic failure of any of our facilities will not occur in the future.

Our strategy of operating large, long-lived, geographically diverse assets has been increasingly dependent on our ability to become fully integrated and highly automated. Many of our business and operational processes utilize traditional and emerging technology systems, including AI, to conduct day-to-day operations, improve safety and efficiency, and lower costs. As our dependence on information systems, including those of our third-party service providers and vendors, grows, we have become more vulnerable to an increasing threat of continually evolving cybersecurity risks. In recent years, cybersecurity events have increased in frequency and magnitude and the methods used to gain unauthorized access change frequently, making it increasingly difficult for us to prevent cybersecurity incidents or detect and remediate incidents in a timely and effective manner. Attacks have included and may include, but are not limited to, installation of malicious software, phishing, ransomware, social engineering tactics and credential attacks, insider threats, denial of service attacks, unauthorized access to data and other advanced and sophisticated cybersecurity breaches and threats, including those that increasingly target critical operational technologies and process control networks and those that are increasingly using AI and machine learning and quantum computing. Such attacks may be perpetrated by a variety of bad actors, some of which may reside in jurisdictions where law enforcement measures to address such attacks are ineffective. We have experienced targeted and non-targeted cybersecurity events in the past and may experience events of a similar nature, with potentially greater exposure, in the future. Cybersecurity threats could subject us to manipulation or improper use of our systems and networks, production downtimes, loss of sales, communication interruption or other disruptions and delays to our operations or to the transportation of products or infrastructure utilized by our operations, unauthorized release of proprietary, commercially sensitive, confidential or otherwise protected information, a misappropriation or loss of funds, the corruption of data, significant health and safety consequences, physical destruction of assets, environmental damage, loss or theft of intellectual property, fines, penalties, litigation, regulatory or governmental investigation, liability under or termination of our contracts with third parties, damage to our reputation or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, results of operations and financial condition, and which in addition could adversely impact the effectiveness of our internal control over financial reporting. We do not maintain cyber risk insurance, and the lack of insurance coverage could adversely affect our cash flows and overall profitability in the event of a cybersecurity incident that has a material adverse effect on our business. While cybersecurity events have not had a material impact on us, we can provide no assurance that we will not experience any such impact or additional interruptions to our operations in the future. Given the unpredictability of the timing and the evolving nature and scope of information and operational technology system disruptions, the various procedures and controls we use to monitor and protect against cybersecurity threats and to mitigate potential risks arising from such threats have not been effective in some instances and may not be sufficient in preventing future cybersecurity incidents. Further, as cybersecurity threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate vulnerabilities to cybersecurity threats. We could also be adversely affected by system or network disruptions if new or upgraded information or operational technology systems are defective, not installed properly or not properly integrated into our operations. System modification failures could have a material adverse effect on our business, financial position and results of operations and could, if not successfully implemented, adversely impact the effectiveness of our internal control over financial reporting. 65 65 65 65 65 65 Table of Contents Table of Contents Table of Contents Further, we increasingly depend on our information technology infrastructure for electronic communications among our operations, personnel, customers and suppliers around the world, including as a result of remote working and flexible working arrangements. These information technology systems, some of which are managed by third parties that we do not control, may be susceptible to damage, disruptions or shutdowns because of failures during the process of upgrading or replacing software, databases or components thereof, cutover activities in our restructuring and simplification initiatives, power outages, hardware failures, telecommunication failures, human errors, catastrophic events or other problems.

Safford is located in Graham County, Arizona, 8 miles north of the town of Safford and 170 miles east of Phoenix. The site is accessible by a paved county road off U.S. Highway 70. The Safford mine includes three copper deposits that have oxide mineralization overlaying primary copper sulfide mineralization. The predominant oxide copper minerals are chrysocolla and copper-bearing iron oxides with the predominant copper sulfide material being chalcopyrite. In recent years, Lone Star has been the only Safford deposit actively being mined. In early 2026, limited mining production resumed in the San Juan deposit. We continue to advance pre-feasibility studies in the Safford/Lone Star district to define a potential significant expansion opportunity. Positive drilling conducted in recent years indicates a large, mineralized district with opportunities to pursue a significant expansion project. We expect to complete these studies during 2026. The decision to proceed with and timing of the potential expansion will take into account results of technical and economic studies, overall copper market conditions and other factors. Safford is a leach operation that consists of a SX/EW facility with a capacity of approximately 320 million pounds of copper cathode per year from a 104,300 metric-ton-per-day crushing facility and a ROM leaching operation. The crushed ore is delivered to a leach pad by a series of overland and portable conveyors. A sulfur burner plant is also in operation at Safford, providing a cost-effective source of sulfuric acid used in SX/EW operations. The available mining fleet consists of fifty-nine 235-metric-ton haul trucks loaded by 9 electric shovels (of which 2 are on standby) with bucket sizes ranging from 36 to 57 cubic meters, which are capable of moving an average of approximately 435,000 metric tons of material per day. At December 31, 2025, Safford’s net PP&E and mine development costs totaled $1.9 billion. Safford’s copper production totaled 287 million pounds in 2025, 249 million pounds in 2024 and 245 million pounds in 2023. Safford is located in a desert environment with rainfall averaging 10 inches per year. The highest bench elevation is 1,783 meters above sea level and the ultimate pit bottom is expected to have an elevation of 716 meters above sea level. The Safford operation encompasses approximately 78,600 acres, comprising 38,000 acres of fee lands and 40,600 acres of unpatented claims held on public mineral estate. The Safford operation’s electrical power is primarily sourced from Tucson Electric Power Company, Arizona Public Service Company and the Luna Energy facility. Although we believe the Safford operation has sufficient water sources to support current operations, we are a party to litigation that may impact our water right claims or rights to continued use of currently available water supplies, which could adversely affect our water supply for the Safford operation.

The site is accessible by a paved highway and by rail. The Miami mine is a porphyry copper deposit that has leachable oxide and secondary sulfide mineralization. The predominant oxide copper minerals are chrysocolla, copper-bearing clays, malachite and azurite. Chalcocite and covellite are the most important secondary copper sulfide minerals. Since about 1915, the Miami mining operation had processed copper ore using both flotation and leaching technologies. The design capacity of the SX/EW plant is 200 million pounds of copper per year. Miami is no longer mining ore, but currently produces copper through leaching material already placed on stockpiles. At December 31, 2025, Miami’s net PP&E and mine development costs totaled $13 million. Miami’s copper production totaled 9 million pounds in both 2025 and 2024, and 12 million pounds in 2023. Miami is located in a desert environment with rainfall averaging 18 inches per year. The highest bench elevation is 1,390 meters above sea level and mining advanced the pit bottom to an elevation of 810 meters above sea level. Subsequent sloughing of material into the pit has filled it back to an elevation estimated to be 900 meters above sea level. The Miami operation encompasses approximately 20,400 acres, comprising 14,700 acres of fee lands and 5,700 acres of unpatented mining claims held on public mineral estate. Miami receives electrical power through long-term contracts with the Salt River Project and natural gas through long-term contracts with El Paso Natural Gas as the transporter.

Because our profits are primarily derived from our mining operations, our ability to replenish our mineral reserves is essential to our long-term success. Depleted mineral reserves can be replaced in several ways, including expanding known ore bodies, reducing operating costs that could extend the life of a mine by allowing us to cost-effectively process ore types that were previously considered uneconomic, investing in and advancing new technologies (such as our leaching innovation initiatives), locating new deposits or acquiring interests in mineral reserves from third parties. Exploration is highly speculative in nature, involves many risks and uncertainties, requires substantial capital expenditures (which may differ significantly from those estimated) and, in some instances, advances in processing technology, and is frequently unsuccessful in discovering significant mineral resources since new, large, long-life deposits are increasingly scarce. Accordingly, our current or future exploration programs may not result in the discovery of additional deposits that can be produced profitably. Even if significant mineral resources are discovered, it will likely take many years from the initial phases of exploration until commencement of production, during which time the economic feasibility of production may change. We may not be able to discover, enhance, develop or acquire mineral reserves in sufficient quantities to maintain or grow our current reserve levels, which could negatively affect our cash flows, results of operations and financial condition."

Bagdad is located in Yavapai County in west-central Arizona, approximately 60 miles west of Prescott and 100 miles northwest of Phoenix. The property can be reached by U.S. Highway 93 to State Route 97 or Arizona Highway 96, which ends at the town of Bagdad. The closest railroad is at Hillside, Arizona, 24 miles southeast on Arizona Highway 96. The Bagdad mine is a porphyry copper deposit containing both sulfide and oxide mineralization. Chalcopyrite and molybdenite are the dominant primary sulfides and are the primary economic minerals in the mine. Chalcocite is the most common secondary copper sulfide mineral, and the predominant oxide copper minerals are chrysocolla, malachite and azurite. The Bagdad operation consists of a concentrator with a milling design capacity of 77,100 metric tons of ore per day that produces copper and molybdenum concentrate, a SX/EW plant that can produce approximately 9 million pounds per year of copper cathode from solution generated by low-grade stockpile leaching, and a pressure-leach plant to process molybdenum concentrate. The available mining fleet consists of 33 autonomous 235-metric-ton haul trucks loaded by 6 electric shovels and 2 loaders with bucket sizes ranging from 30 to 48 cubic meters, which are capable of moving an average of 236,000 metric tons of material per day. Bagdad’s fleet also includes 7 manned haul trucks that are primarily operated for mine development and maintenance activities. At December 31, 2025, Bagdad’s net PP&E and mine development costs totaled $1.4 billion. Bagdad’s production totaled 149 million pounds of copper and 11 million pounds of molybdenum in 2025, 146 million pounds of copper and 13 million pounds of molybdenum in 2024, and 146 million pounds of copper and 10 million pounds of molybdenum in 2023. We have defined an opportunity to more than double the concentrator capacity of the Bagdad operation. Bagdad’s reserve life currently exceeds 80 years and supports an expanded operation. We completed technical and economic 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. Estimated incremental project capital 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. Preliminary economics indicate that the expansion would require an incentive copper price of approximately $4.00 per pound and three to four years to complete. The decision to proceed with and timing of the potential expansion will take into account overall copper market conditions and other factors. Conversion of Bagdad’s haul truck fleet to autonomous haulage was completed in 2025, making Bagdad the first major mine in the U.S. to operate a fully autonomous haulage fleet.

Prices of consumables used in our operations (such as natural gas, diesel, coal, other sources of energy, ammonium nitrate, chemical reagents, including sulfuric acid, and steel-related products), certain components, equipment, parts and other operating supplies and services can fluctuate in price, impacting the costs of production at our operations and the costs of development projects. We have experienced price volatility for certain consumables, which has impacted our operating results, and we may experience volatility in the price and availability of other consumables in the future. Significant volatility or further increases could have a material adverse effect on our results of operations and could result in material changes to our operating plans or development projects. Ensuring continuity of supply of such consumables to our operations is critical to our business. We also rely on the availability of components from suppliers for key machines and equipment, which may be impacted by competition demands as well as the availability of input materials in the creation of such equipment. A supplier’s failure to supply consumables or components in a timely or cost-effective manner or to meet our specifications, or our inability to obtain alternative sources on a timely basis or on terms acceptable to us, could adversely affect our operations. Delays and logistical constraints may occur as a result of weather-related impacts, geopolitical tensions or conflicts (including trade policies such as tariffs and other controls on exports and imports), or violence, civil and religious strife, and activism at or near our operations or those of our suppliers, as described in the related risk factor below. Following any interruption to our business, we can require substantial recovery time, experience significant expenditures to resume operations, and lose significant revenues, which could have a material adverse effect on our results of operations. Because we may rely on limited sources and long-lead times for consumables and components for key machines and equipment, a business interruption affecting or requiring such sources would exacerbate any negative consequences to us. Our business depends on timely inbound transportation of consumables and components we use and outbound transportation of the commodities we produce such as by truck, rail and ocean freight. Any significant increase in the cost of or significant delays in the transportation of consumables or components used in our operations or the commodities we produce, as a result of increases in fuel or labor costs, higher demand for logistics services, weather-related impacts (such as low water levels along shipping routes) or otherwise, could adversely affect our results of operations. Additionally, if transportation service providers fail to deliver consumables or components used in our operations to us or the commodities we produce to our customers in a timely manner or at all, such failure could adversely impact our ability to meet our production schedules, delay our projects and capital initiatives, negatively affect our customer relationships and have a material adverse effect on our financial position and results of operations."

Our wholly owned Climax mine is an open-pit molybdenum mine that is located 13 miles northeast of Leadville, Colorado, off Colorado State Highway 91 at the top of Fremont Pass. The mine is accessible by paved roads. Climax was placed on care and maintenance status by its previous owner in 1995 and, after being acquired by FMC, began commercial production in 2012. The Climax ore body is a porphyry molybdenum deposit, with molybdenite as the primary sulfide mineral. The Climax mine includes a 25,000 metric tons of ore per day mill facility and has the capacity to produce approximately 30 million pounds of molybdenum per year. The majority of the molybdenum concentrate produced is shipped to our Fort Madison, Iowa, processing facility. The available mining fleet consists of fourteen 177-metric-ton haul trucks loaded by two hydraulic shovels with bucket sizes of 34 cubic meters, which are capable of moving an average of 90,000 metric tons of material per day. At December 31, 2025, Climax’s net PP&E and mine development costs totaled $1.4 billion. Climax’s molybdenum production totaled 24 million pounds in 2025, 18 million pounds in 2024 and 17 million pounds in 2023. The Climax mine is located in a mountainous region. The highest bench elevation is approximately 4,050 meters above sea level and the ultimate pit bottom is expected to have an elevation of approximately 3,100 meters above sea level. This region experiences significant snowfall during the winter months. The Climax operation encompasses approximately 15,100 acres of fee lands. Climax operations receive electrical power through long-term contracts with Xcel Energy and natural gas supply with Spark Energy Gas (with Xcel Energy as the transporter). We believe the Climax operation has sufficient water sources to support current operations. Refer to “Governmental Regulations” above and Item 1A. “Risk Factors” for further discussion. Henderson. Our wholly owned Henderson molybdenum mining complex has been in operation since 1976. Henderson is located 42 miles west of Denver, Colorado, off U.S. Highway 40.

The Henderson mine and mill are connected by a 10-mile conveyor tunnel under the Continental Divide and an additional 5-mile surface conveyor. The tunnel portal is located 5 miles east of the mill. The Henderson mine is a porphyry molybdenum deposit, with molybdenite as the primary sulfide mineral. 18 18 18 18 18 18 Table of Contents Table of Contents Table of Contents The Henderson operation consists of a block-cave underground mining complex feeding a concentrator with a design capacity of approximately 32,000 metric tons of ore per day. Henderson has the capacity to produce approximately 15 million pounds of molybdenum per year. The majority of the molybdenum concentrate produced is shipped to our Fort Madison, Iowa, processing facility. The available underground mining equipment fleet consists of fifteen 9-metric-ton load-haul-dump (LHD) units and five 63-metric-ton haul trucks, which deliver ore to a gyratory crusher feeding a series of three conveyors to the mill stockpiles. At December 31, 2025, Henderson’s net PP&E and mine development costs totaled $312 million. Henderson’s molybdenum production totaled 13 million pounds in 2025, 12 million pounds in 2024 and 13 million pounds in 2023. The Henderson mine is located in a mountainous region with the main access shaft at 3,180 meters above sea level. The main production levels are currently at elevations of 2,200 and 2,350 meters above sea level. This region experiences significant snowfall during the winter months. The Henderson mine and mill operations encompass approximately 17,200 acres, comprising 13,000 acres of fee lands, 4,200 acres of unpatented mining claims held on public mineral estate and a 50-acre easement with the U.S. Forest Service for the surface portion of the conveyor corridor.

We aim to balance our operational water requirements with those of the local communities, environment and ecosystems. We recognize that access to clean, safe and reliable water supply is vital to the health and livelihood of our host communities. Most of our U.S. and South America operations are in areas where competition for water supplies is significant. Continuous production at our operations and any future expansions or developments are dependent on many factors, including our ability to maintain our water rights and claims, and the continuing physical availability of the water supplies. Current and long-term water risks include those that arise from our operations and events that we do not control (such as extreme weather). As discussed in Item 3. “Legal Proceedings,” in Arizona, where our operations use both surface water and groundwater, we are a participant in an active adjudication in which Arizona courts have been attempting, for 50 years, to quantify and prioritize surface water claims for the Gila River watershed, one of the state’s largest river systems. If we are not able to satisfactorily resolve the issues being addressed in the adjudications, our water uses could be diminished or curtailed, and our operations and any future expansions at Morenci, Safford (including Lone Star) and Sierrita could be adversely affected unless we are able to acquire alternative water sources. Water for our Cerro Verde operation in Peru comes from renewable sources through a series of storage reservoirs on the Rio Chili watershed that collects water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant constructed by us. As a result of certain weather patterns, water shortages at our Cerro Verde operation are possible, which could impact our operations. Water for our El Abra operation in Chile currently comes from the continued pumping of groundwater from the Salar de Ascotán aquifer. The agreement to pump from this aquifer is subject to continued monitoring through 2029 of the aquifer water levels and select flora species to ensure that environmentally sensitive areas are not impacted by our pumping, which if impacted could cause reductions in pumping to restore water levels and could have an adverse effect on production from El Abra. Our permit for pumping of groundwater will expire in 2029, and we anticipate filing applications to request an extension of the use of water from the Salar de Ascotán during 2026. Any renewal or provisional extension may be challenging. We are evaluating water infrastructure alternatives to provide options to extend existing operations and support a future expansion, while continuing to monitor Chile’s regulatory and fiscal matters, as well as trends in capital costs for similar projects. There can be no assurance that we will be able to execute such water infrastructure plans or obtain a new permit or provisional extension, which could have an adverse impact on our operations. For further discussion, see the risk factor above relating to the geopolitical, economic and social risks associated with our operations. Although our operations currently have access to sufficient water sources to support current operational demands, as discussed above, the availability of additional supplies for potential future expansions or development will require additional investments and will take time to develop, if available. While we are taking actions to acquire additional back-up water supplies for current and future mining operations, such supplies may not be available at acceptable cost, or at all. As such, the loss of a water right or currently available water supply could force us to curtail operations or force premature closures, and the inability to obtain future water supplies could prevent future expansions or developments, thereby increasing and/or accelerating costs or foregoing profitable operations. 64 64 64 64 64 64 Table of Contents Table of Contents Table of Contents We typically have sufficient water for our Indonesia operations, but at times and for reasons out of our control, we may have too much or not enough. The PTFI project area receives considerable rainfall that makes it susceptible to periodic floods and mudslides, the nature and magnitude of which cannot be predicted.

Proven and probable mineral reserves were determined from the application of relevant modifying factors to geological data to establish an operational, economically viable mine plan. The estimates are based on mapping, drilling, sampling, assaying and evaluation methods generally applied in the mining industry. Mineral reserves, as used in the mineral reserve data presented here, means the economically mineable part of a measured or indicated resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. Proven mineral reserves mean the economically mineable part of a measured mineral resource, from geological evidence revealed in outcrops, trenches, workings or drill holes with grades and/or quality estimates from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence. Probable mineral reserves means the economically mineable part of an indicated mineral resource, for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate. Probable mineral reserves can also include remaining portions of a measured mineral resource. The degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation. Our estimates of recoverable proven and probable mineral reserves are prepared by and are the responsibility of our employees. These estimates are reviewed and verified regularly by independent experts in mining, geology and reserve determination.

Maintaining the operational integrity and performance of our assets is crucial to protect our people, the environment and communities in which we operate. Our operations are very large in scale and, by their nature are subject to significant operational risks, some of which are outside of our control, and many of which are not covered fully, or in some cases even partially, by insurance. These operational risks, which could materially adversely affect our business, operating results and cash flows, include earthquakes, rainstorms, floods, landslides, wildfires and other natural disasters and extreme weather events; environmental hazards, including discharge of metals, concentrates, pollutants or hazardous chemicals; surface or underground fires; equipment failures; accidents, including in connection with mining equipment, milling equipment or conveyor systems, transportation of chemicals, explosives or other materials and in the transportation of employees and other individuals to and from sites (including where these services are provided by third parties such as vehicle and aircraft transport); wall failures and rock slides in our open-pit mines, and structural collapses of our underground mines or tailings impoundments; underground water and ore management; lower than expected ore grades or recovery rates; and seismic activity resulting from unexpected or difficult geological formations or conditions (whether in mineral or gaseous form). For a discussion of risks specific to our tailings management, see the risk factors below relating to our management of waste rock and tailings, including our river transport system for tailings management in Indonesia. 59 59 59 59 59 59 Table of Contents Table of Contents Table of Contents We are facing continued geotechnical challenges because of the older age of some of our mines and a trend toward mining deeper pits and more complex deposits. There can be no assurance that unanticipated geotechnical and hydrological conditions may not occur, nor whether these conditions may lead to events such as landslides and pit wall failures, or that such events will be detected in advance. Geotechnical instabilities can be difficult to predict and are often affected by risks and hazards outside of our control, such as seismic activity or extreme weather, which have in the past and may in the future lead to floods, mudslides, pit-wall instability and possibly even slippage of material, which has and may in the future require suspension of operations and impact operating results. We also experience mining induced seismic activity, including landslides, from time to time in the Grasberg minerals district in addition to extreme weather. The mine site is in an active seismic area and has experienced earth tremors from time to time. In addition to the usual risks encountered in the mining industry, our Indonesia mining operations involve additional risks given their location in steep mountainous terrain in a remote area of Indonesia. These conditions have required us to overcome special engineering difficulties and develop extensive infrastructure facilities. The area also receives extreme rainfall, which has led to periodic floods and mudslides. We cannot predict whether weather-related or seismic events will occur in the future or the extent to which any such event would affect our operations. Underground mining operations have unique risks that can be particularly dangerous, such as those associated with supporting the underground openings, a cave not propagating as anticipated, unplanned ground movement occurring from changes in stresses released in the surrounding rock, excessive water ingress and the presence of fine materials may also give rise to unplanned releases of material of varying properties and of water through drawbells or other openings. In September 2025, an unprecedented and unforeseeable mud rush incident occurred at the Grasberg Block Cave underground mine, which resulted in seven fatalities. Refer to the risk factor above and MD&A for further discussion of the September 2025 mud rush incident. In May 2013, the rock structure above the ceiling of an underground training facility at the Big Gossan in the Grasberg minerals district collapsed, which resulted in 28 fatalities and 10 injuries. While we have implemented and will continue to implement preventative measures and enhanced operating procedures, we cannot guarantee that any incidents will not occur in the future. The occurrence of one or more of these operational risks in connection with our operations may result in the death of, or personal injury or illness to, our employees, other personnel or third parties, the loss of mining equipment, damage to or destruction of mineral properties or production facilities, significant repair costs, monetary losses, deferral or unanticipated fluctuations in production, extensive community disruption (including short- and long-term health and safety risks), loss of licenses, permits or necessary approvals to operate, loss of workforce confidence, loss of infrastructure and services, disruption to essential supplies or delivery of our products, environmental damage and potential legal liabilities, any of which may adversely affect our reputation, business, prospects, results of operations and financial position. Further, the impacts of any serious incidents that occur may also be amplified if we fail to respond timely or in an appropriate manner. In addition, we could also be subject to additional operational risks at our smelters and refineries, including those specific to PTFI. Any delay, suspension, loss of access, shutdown of affected facilities or limited availability and capacity related to these smelting and refinery facilities, including equipment or mechanical failures, fires, explosions, unanticipated or extended shutdowns, inability to sell certain by-products, lack of capacity to store certain by-products, extreme weather or natural disasters, social or political unrest or any major public health crisis, any of which may not be recognized as a force majeure event, may significantly impact our ability to export and sell our products, particularly in Indonesia even if alternative refineries or smelters outside of Indonesia are available, and could adversely impact our costs, revenues and results of operations or require us to revise our operating plans, including curtailing or modifying our mining and milling operations. As discussed above and in Note 10, smelting operations in Indonesia were temporarily suspended during fourth-quarter 2025 as a result of limited copper concentrate availability following the September 2025 mud rush incident. We maintain insurance at amounts we believe to be reasonable to cover some of these risks and hazards; however, our insurance may not sufficiently cover losses from certain of these risks and hazards. There can be no assurance that such insurance will continue to be maintained or available at economically feasible premiums, that the proceeds of such insurance will be paid in a timely manner or that we will be adequately compensated for losses actually incurred, if at all. We may elect not to purchase insurance for certain risks because of the high premium costs associated with insuring such risk or for various other reasons. For example, we do not have coverage for certain environmental losses, including the legal liabilities associated with these risks. The lack of, or insufficiency of, insurance coverage could adversely affect our cash flows and overall profitability. 60 60 60 60 60 60 Table of Contents Table of Contents Table of Contents"

Activities that occurred in the late 19th century and the 20th century prior to the advent of modern environmental laws generally were not subject to environmental regulation and were conducted before U.S. industrial companies fully understood the long-term effects of their operations on the surrounding environment. Companies like FMC are legally responsible for remediating hazardous substances released into the environment on or from properties owned or operated by them as well as properties where they arranged for disposal of such substances, irrespective of when the release into the environment occurred or who caused it. That liability is often asserted on a joint and several basis with other prior and subsequent owners, operators and arrangers, meaning that each owner or operator of the property is, and each arranger may be, held fully responsible for the remediation, although in many cases some or all of the other responsible parties no longer exist, do not have the financial ability to respond or cannot be found. As a result, because of our acquisition of FMC, many of the subsidiary companies we now own are potentially responsible for a wide variety of environmental remediation projects throughout the U.S., and we expect to spend substantial sums annually for many years to address those remediation issues. We are also subject to claims where the release of hazardous substances is alleged to have resulted in injury, destruction or loss of natural resources. At December 31, 2025, we had more than 80 active remediation projects in 23 U.S. states. In addition, FMC and certain affiliates and predecessor companies were parties to agreements relating to the transfer of businesses or properties that contained indemnification provisions relating to environmental matters, and from time to time these provisions become the source of claims against us. Our environmental obligation estimates are primarily based upon our current knowledge and understanding of: •Complex scientific and historical facts and circumstances that in many cases occurred many decades ago; •Assumptions regarding the nature, extent and duration of remediation activities that we will be required to undertake and the estimated costs of those remediation activities, which are subject to varying interpretations; and •Interpretation of the requirements that are imposed on us by existing laws and regulations and, in some cases, the clarification of uncertain regulatory requirements that could materially affect our environmental obligation estimates. Significant adjustments to these estimates are likely to occur in the future as additional information becomes available. The actual environmental costs may exceed our current and future accruals for these costs, and any such changes could be material. In addition, remediation standards imposed by EPA and state environmental agencies have generally become more stringent over time and may become even more stringent in the future. Imposition of more stringent remediation standards, particularly for arsenic and lead in soils, poses a risk that additional remediation work could be required at our active remediation sites and at sites that we have already remediated to the satisfaction of the responsible governmental agencies, and may increase the risk of toxic tort litigation.

Further, we may not be able to timely or successfully transition from fossil fuel sources for our significant energy needs, which may result in reputational damage.",
      "current_body": "Our operations require significant energy, much of which is currently from fossil fuel sources and is obtained from third parties under long-term contracts. Energy represented 15% of our copper mine site operating costs in 2025, and based on currently available information and projected operations, is expected to approximate 17% in 2026. The principal sources of energy consumption at our mining operations are: diesel fuel, which powers mine trucks 70 70 70 70 70 70 Table of Contents Table of Contents Table of Contents and other transportation equipment; purchased electricity, which powers core facilities and certain on-site metal processing operations; and coal and natural gas, which provide electricity at certain operations. Existing, proposed and future governmental conventions, laws, rules, regulations, policies and standards as well as existing, proposed and future voluntary disclosure standards and frameworks (both in the U.S. and internationally), including those related to changing climate conditions, carbon taxes, carbon markets or greenhouse gas (GHG) emissions, may in the future add significantly to our operating costs, limit or modify our operations, impact the competitiveness of the commodities we produce, and require more resources to comply and remediate in response. For additional information refer to Items 1. and 2. “Business and Properties.” In response to changing climate conditions and societal or stakeholder demands for action, we are advancing 2030 GHG emissions reduction targets and a 2050 net zero aspiration, each of which will result in additional costs to us, the totality of which we cannot currently estimate with accuracy. In addition, there can be no assurance that we will be able to achieve any current or future GHG emissions targets or aspirations or that such targets or aspirations will not be adjusted in the future. While we strive to include more renewable power among the energy sources for our mining operations, as a commercial consumer of power, our ability to reduce our GHG emissions associated with our power consumption demand is largely dependent upon the mix of our suppliers and locally available renewable energy resources at our various sites, including our ability to successfully develop renewable energy projects and negotiate power purchase agreements. The transition to renewable and other energy sources could, among other things, increase our capital expenditures, and operating and energy costs, depending on the scope, magnitude and timing of increased regulation of fossil-fuel based energy production, including GHG emissions, as well as the availability of alternative energy sources. In certain aspects of our operations, our ability to reduce our GHG emissions is directly dependent on the actions of third parties and technological solutions and innovation, and our ability to make significant, rapid changes in our GHG emissions in response to potential future regulations may be limited. For example, our diesel-fueled haul trucks are a significant contributor to GHG emissions at our U.S. and South America operations. We are evaluating options for transitioning to more energy efficient haul trucks, including electrification, but reduction of emissions from such haul trucks will depend upon the development and availability of commercially viable alternative-fueled mining equipment by our third-party suppliers. At our remote mining operations in Indonesia, PTFI owns and operates a coal-fired power plant and expects to advance plans to transition its existing energy source from coal to natural gas following a deferral of certain projects after the September 2025 mud rush incident. Our ability to transition to commercially viable alternative sources of energy across our operations globally will depend on, among other things, additional studies, technological considerations, or permit or other approvals. Even if we do implement new technologies, our stakeholders and other third parties may not be satisfied with our approach to reducing our GHG emissions. For further discussion, see the risk factor below relating to the scrutiny and evolving expectations from stakeholders and other third parties, including creditors, with respect to our sustainability-related practices, performance and disclosures."
