Consolidated Sales Volumes

Copper

•Second-quarter 2026 sales of 710 million pounds were higher than the April 2026 estimate of 690 million pounds, primarily reflecting timing of shipments and improved operating performance. As expected, second-quarter 2026 sales were below second-quarter 2025 sales of 1.0 billion pounds, primarily reflecting lower operating rates at PTFI during the phased ramp-up of the Grasberg Block Cave underground mine.

Gold

•Second-quarter 2026 sales of 123 thousand ounces were lower than the April 2026 estimate of 140 thousand ounces, primarily reflecting the timing of refined gold shipments in Indonesia. As expected, second-quarter 2026 sales were below second-quarter 2025 sales, reflecting lower operating rates at PTFI during the phased ramp-up of the Grasberg Block Cave underground mine.

Molybdenum

•Second-quarter 2026 sales of 25 million pounds were higher than both the April 2026 estimate and second-quarter 2025 sales of 22 million pounds, primarily reflecting a reduction in inventory.

Consolidated sales volumes for the year 2026 are expected to approximate 3.1 billion pounds of copper, 650 thousand ounces of gold and 93 million pounds of molybdenum, including 750 million pounds of copper, 160 thousand ounces of gold and 22 million pounds of molybdenum in third-quarter 2026.

Consolidated copper and gold production volumes for the year 2026 are expected to exceed sales volumes, reflecting deferrals of approximately 100 million pounds of copper and 50 thousand ounces of gold associated with inventory held at PTFI’s smelting operations.

Consolidated Unit Net Cash Costs

Consolidated unit net cash costs (net of by-product credits and excluding idle facility and restoration costs associated with the phased ramp-up of the Grasberg Block Cave underground mine) for FCX’s copper mines averaged $1.97 per pound of copper in second-quarter 2026, which were favorable to the April 2026 estimate of $2.24 per pound, primarily reflecting higher molybdenum by-product credits and copper volumes. Second-quarter 2026 average unit net cash costs were unfavorable to second-quarter 2025 average unit net cash costs of $1.13 per pound of copper, primarily reflecting the impact of lower copper volumes at PTFI.

During the phased ramp-up period of the Grasberg Block Cave underground mine and until PTFI’s operations return to normal capacity, a portion of PTFI's production and delivery costs will be recognized as idle facility costs, which are non-inventoriable. Idle facility and restoration costs totaled $284 million in second-quarter 2026 and $690 million for the first half of 2026, which were excluded from consolidated net cash costs.

Based on achievement of current sales volume and cost estimates and assuming average prices of $4,000 per ounce of gold and $30.00 per pound of molybdenum for the second half of 2026, G8consolidated unit net cash costs (net of by-product credits and excluding idle facility and restoration costs) for FCX’s copper mines are expected to average $1.90 per pound of copper for the year 2026 (including $2.00 per pound of copper in third-quarter 2026).

The impact of price changes on consolidated unit net cash costs for the second half of 2026 would approximate $0.02 per pound of copper for each $100 per ounce change in the average price of gold and $0.03 per pound of copper for each $2 per pound change in the average price of molybdenum.

Projected sales volumes and unit net cash costs for the year 2026 are dependent on operational performance; the phased ramp-up of the Grasberg Block Cave underground mine at PTFI; changes in energy costs and other consumables; weather-related conditions; timing of shipments and other factors detailed in the “Cautionary Statement” below.

OPERATIONS

Leaching and Technology Innovation Initiatives. FCX is incorporating new applications, technologies and data analytics into its leaching processes across its United States (U.S.) and South America operations. Incremental copper production from these initiatives totaled 47 million pounds in second-quarter 2026 and 101 million pounds for the first six months of 2026.

FCX continues to apply operational enhancements on a larger scale and is advancing testing of innovative technologies to target significant increases in incremental production from leaching initiatives. T3FCX is targeting reaching an annual run rate of 300 million pounds of copper from these initiatives by the end of 2026, with potential for further significant increases in recoverable metal in future years. FCX is deploying large-scale testing of an internally developed additive product at its Morenci operations with encouraging early results. In addition, FCX plans to field-test two additional additives which, together with the application of heat to its stockpiles, could further enhance recoveries. Continued success with these initiatives would be expected to contribute to additions in recoverable copper in leach stockpiles and favorably impact average unit net cash costs.

In addition to its innovative leaching initiatives, FCX is pursuing opportunities to leverage new technologies and analytic tools in automation and operating practices with a goal of improving operating efficiencies and reducing costs and capital intensity of its current operations and future development projects. FCX believes its innovative leaching and technology initiatives will strengthen its operational performance and enhance opportunities for profitable growth.

United States. FCX manages seven copper operations in the U.S. – Morenci, Bagdad, Safford (including Lone Star), Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. FCX also operates a copper smelter and rod mill in Miami, Arizona, and a copper refinery and rod mill in El Paso, Texas. In addition to copper, certain of these operations produce molybdenum concentrate, gold and silver.

All of FCX’s U.S. operations are wholly owned, except for Morenci. FCX records its 72% undivided joint venture interest in Morenci using the proportionate consolidation method.

Development Activities. FCX has substantial reserves, resources and future opportunities for organic growth in the U.S. associated with existing operations. Several initiatives are underway to target significant future growth in U.S. copper operations, including the leaching and technology innovation initiatives discussed above.

4

FCX has defined an opportunity to more than double the concentrator capacity of the Bagdad operation in northwest Arizona. Bagdad’s reserve life currently exceeds 80 years and supports an expanded operation. FCX completed technical and economic studies in late 2023 and has advanced these studies in preparation for a potential investment decision during the second half of 2026. These studies indicate the opportunity to construct new concentrating facilities to increase copper production by 200 to 250 million pounds per year and increase molybdenum production by 10 to 12 million pounds per year. Expanded operations would position Bagdad as the second largest copper mine in the U.S. (behind FCX’s flagship Morenci mine) and among the lowest cost mines in FCX’s U.S. portfolio, and Bagdad would benefit from improved efficiency and lower unit net cash costs through economies of scale.

Capital cost estimates are being finalized, taking into account current estimates, including for materials, equipment and labor. T4Current estimates, which continue to be reviewed, indicate project capital cost increases of approximately 30% above the prior $3.5 billion estimate prepared in 2023. The revisions incorporate the impact of cost escalation, revisions in scope and revised estimates associated with additional engineering. Taking into account higher capital cost estimates and enhanced operational plans, the project economics continue to be supported at an incentive copper price of approximately $4.00 per pound and would require 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.

FCX continues 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. FCX expects 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.

FCX’s consolidated copper sales volumes from the U.S. copper mines totaled 312 million pounds in second-quarter 2026 and 308 million pounds in second-quarter 2025. G9Consolidated copper sales from FCX’s U.S. copper mines are expected to approximate 1.4 billion pounds for the year 2026.

Average unit net cash costs (net of by-product credits) for the U.S. copper mines of $2.94 per pound of copper in second-quarter 2026 were lower than second-quarter 2025 average unit net cash costs of $3.04 per pound of copper, primarily reflecting higher by-product credits, partly offset by higher costs for supplies, diesel fuel and other consumables.

5

G10Based on achievement of current sales volume and cost estimates and assuming an average price of $30.00 per pound of molybdenum for the second half of 2026, average unit net cash costs (net of by-product credits) for the U.S. copper mines are expected to approximate $2.96 per pound of copper for the year 2026. The U.S. copper mines’ average unit net cash costs for the year 2026 would change by approximately $0.03 per pound for each $2 per pound change in the average price of molybdenum for the second half of 2026.

South America. FCX manages two copper operations in South America – Cerro Verde in Peru (55.66%-owned) and El Abra in Chile (51%-owned). These operations are consolidated in FCX’s financial statements. In addition to copper, the Cerro Verde mine produces molybdenum concentrate and silver.

Development Activities. At the El Abra operations in Chile, FCX has an attractive opportunity to expand the operation to include a major mill facility 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. In March 2026, El Abra submitted an environmental impact study to Chile regulatory authorities. 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 required permitting, market conditions and other factors.

FCX’s consolidated copper sales volumes from South America operations of 245 million pounds in second-quarter 2026 were lower than second-quarter 2025 copper sales volumes of 265 million pounds, primarily reflecting lower leach production and the processing of lower grade stockpile ore as a result of mine sequencing. Copper sales from South America operations are expected to approximate 1.0 billion pounds for the year 2026.

Average unit net cash costs (net of by-product credits) for South America operations of $2.48 per pound of copper in second-quarter 2026 were slightly higher than second-quarter 2025 average unit net cash costs of $2.46 per pound of copper, primarily reflecting lower copper volumes, and higher labor and energy costs, partially offset by higher by-product credits.

G11Based on achievement of current sales volume and cost estimates and assuming an average price of $30.00 per pound of molybdenum for the second half of 2026, average unit net cash costs (net of by-product credits) for South America operations are expected to approximate $2.56 per pound of copper for the year 2026.

6

South America operations’ average unit net cash costs for the year 2026 would change by approximately $0.04 per pound for each $2 per pound change in the average price of molybdenum for the second half of 2026.

Indonesia. PTFI operates one of the world’s largest copper and gold mines at the Grasberg minerals district in Central Papua, Indonesia. In addition to copper and gold, the Grasberg minerals district also produces silver. With the completion of its downstream processing facilities, PTFI is a fully integrated producer of refined copper, gold and silver. FCX has a 48.76% ownership interest in PTFI and manages its operations. PTFI’s results are consolidated in FCX’s financial statements.

Operating, Development and Exploration Activities. Over a multi-year investment period, PTFI has successfully commissioned three large-scale underground mines in the Grasberg minerals district (Grasberg Block Cave, Deep Mill Level Zone (DMLZ) and Big Gossan) and completed 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.

PTFI has identified additional exploration targets to leverage its infrastructure in the Grasberg minerals district, including a potential extension below the DMLZ underground mine, which requires further drilling and evaluation.

Kucing Liar. Since 2022, PTFI has conducted long-term mine development activities at its Kucing Liar deposit in the Grasberg minerals district. PTFI’s long-term mine plans include a ramp-up of Kucing Liar, commencing in the 2030 timeframe, to a design capacity of approximately 130,000 metric tons of ore per day. Average annual Kucing Liar production at full rates would approximate 750 million pounds of copper and 735 thousand ounces of gold and would enable continuity of large-scale production in the Grasberg minerals district.

At June 30, 2026, PTFI had incurred approximately $1.4 billion for Kucing Liar development, and capital investments are estimated to approximate an additional $4 billion through 2033 (averaging approximately $0.5 billion per year).

Long-Term Mining Rights. T5In February 2026, FCX and PTFI entered into a Memorandum of Understanding (MOU) with the Indonesia government for a life of resource extension of operating rights in the Grasberg minerals district beyond the current expiration in 2041. Under the terms of the MOU, FCX would maintain its current ownership interest in PTFI of 48.76% through 2041 and hold approximately 37% beginning in 2042. The existing governance and operating structure, and terms of the existing shareholder agreement, special mining business license (IUPK) and other agreements in effect will continue over the life of the resource.

In June 2026, PTFI submitted its application for extension of its IUPK, and FCX and PTFI are working with the Indonesia government to complete the formal license process. 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.

Grasberg Block Cave Ramp-Up. Following the September 2025 external mud rush incident, PTFI has progressed a series of activities to address the incident and remains focused on a safe and sustainable ramp-up to full operating capacity.

PTFI completed remediation and restoration activities required for the restart of Production Blocks 2 and 3 and commenced initial ramp-up activities at the end of March 2026. T6During second-quarter 2026, PTFI made steady progress on its phased ramp-up and achieved its planned operating rates for the period. Planned upgrades to the material handling system at the Grasberg Block Cave haulage level are advancing on schedule.

PTFI continues to advance activities for a planned future restart of Production Block 1S and risk mitigation strategies associated with drainage and cave management technologies.

PTFI’s overall production rates are expected to approximate 65% in the second half of 2026, 80% by mid-2027 and approach full capacity by the end of 2027.

Downstream Processing Facilities. PTFI’s smelter and PT Smelting, PTFI’s 66%-owned smelter and refinery in Gresik, Indonesia, smelt and refine copper concentrate from PTFI, and the Precious Metals Refinery (PMR) processes anode slimes from PTFI’s smelter and PT Smelting.

During the phased ramp-up period of the Grasberg Block Cave underground mine, smelting operations in Indonesia at both PTFI’s smelter and PT Smelting were adjusted as a result of limited copper concentrate availability. By the end of second-quarter 2026, PT Smelting was operating at capacity and shipments to PTFI’s

7

smelter are expected to recommence in the second half of 2026 at a reduced rate dependent on available copper concentrate from PTFI’s mining operations.

The PMR continues to operate on a limited basis following the September 2025 external mud rush incident, primarily processing anode slimes from PT Smelting.

FCX expects higher variability between PTFI’s production and sales until its downstream processing facilities achieve normalized operating rates.

Favorable offsets associated with incremental metals and sulfuric acid produced by PT Smelting and PTFI’s downstream processing facilities are included in revenues and by-product credits.

PTFI’s consolidated sales volumes of 153 million pounds of copper and 118 thousand ounces of gold in second-quarter 2026 were lower than second-quarter 2025 sales volumes of 443 million pounds of copper and 518 thousand ounces of gold, reflecting lower operating rates at PTFI during the phased ramp-up of the Grasberg Block Cave underground mine.

PTFI’s unit net cash credits (including by-product credits) of $0.81 per pound of copper in second-quarter 2026 were lower than second-quarter 2025 unit net cash credits of $0.99 per pound of copper, primarily reflecting lower copper volumes.

During the phased ramp-up period of the Grasberg Block Cave underground mine and until PTFI’s operations return to normal capacity, a portion of PTFI’s production and delivery costs will be recognized as idle facility costs, which are non-inventoriable. Idle facility and restoration costs totaled $284 million ($1.86 per pound of copper) in second-quarter 2026 and $690 million ($2.93 per pound of copper) for the first six months of 2026, which were excluded from PTFI's unit net cash credits.

G12Consolidated sales volumes from PTFI are expected to approximate 0.7 billion pounds of copper and 650 thousand ounces of gold for the year 2026. Copper and gold production volumes for the year 2026 are expected to

8

exceed sales volumes, reflecting deferrals of approximately 100 million pounds of copper and 50 thousand ounces of gold associated with inventory held at PTFI’s smelting operations.

G13Based on achievement of current sales volume and cost estimates and assuming an average price of $4,000 per ounce of gold for the second half of 2026, average unit net cash credits (including by-product credits and excluding idle facility and restoration costs) for PTFI are expected to approximate $1.22 per pound of copper for the year 2026. PTFI’s average unit net cash credits for the year 2026 would change by approximately $0.06 per pound of copper for each $100 per ounce change in the average price of gold for the second half of 2026.

Molybdenum Mines. FCX operates two wholly owned primary molybdenum operations in Colorado – the Climax open-pit mine and the Henderson underground mine. The Climax and Henderson mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of the molybdenum concentrate produced at the Climax and Henderson mines and at FCX’s U.S. copper mines and Cerro Verde mine is processed at FCX’s conversion facilities.

Operating and Development Activities. Production from the Molybdenum mines totaled 8 million pounds of molybdenum in second-quarter 2026 and 9 million pounds in second-quarter 2025. FCX’s consolidated molybdenum sales and average realized prices include sales of molybdenum produced at the primary molybdenum operations and at FCX’s U.S. copper mines and Cerro Verde mine, which are presented on page 3.

Average unit net cash costs for the Molybdenum mines of $19.20 per pound of molybdenum in second-quarter 2026 were higher than average unit net cash costs of $14.20 per pound in second-quarter 2025, primarily reflecting lower volumes and higher costs for supplies, energy and labor. G14Average unit net cash costs for the Molybdenum mines are expected to approximate $17.91 per pound of molybdenum for the year 2026, based on achievement of current sales volume and cost estimates.

For a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in FCX’s consolidated financial statements, refer to the supplemental schedules, “Product Revenues and Production Costs,” beginning on page XIV.

LIQUIDITY, CASH FLOWS, CASH AND DEBT

Liquidity. At June 30, 2026, FCX had $4.1 billion in consolidated cash and cash equivalents. FCX also had $3.0 billion of availability under its revolving credit facility, and PTFI and Cerro Verde had $1.5 billion and $350 million, respectively, of availability under their revolving credit facilities.

Operating Cash Flows. In second-quarter 2026, FCX generated operating cash flows of $2.0 billion, net of $0.6 billion of working capital and other uses, including tax payments, and included $0.7 billion in pre-tax proceeds collected by PTFI for an insurance settlement associated with the September 2025 external mud rush incident under its property and business interruption policies.

FCX’s consolidated operating cash flows are expected to approximate $8.3 billion for the year 2026, net of $0.3 billion of working capital and other uses, based on current sales volume and cost estimates, and assuming prices of $6.00 per pound of copper, $4,000 per ounce of gold and $30.00 per pound of molybdenum for the second half of 2026. The impact of price changes for the second half of 2026 on operating cash flows would approximate $150 million for each $0.10 per pound change in the average price of copper, $40 million for each $100 per ounce change in the average price of gold and $45 million for each $2 per pound change in the average price of molybdenum.

Capital Expenditures. Capital expenditures totaled $1.1 billion in second-quarter 2026, including $0.7 billion for major mining projects, and $2.1 billion for the first six months of 2026, including $1.3 billion for major mining projects.

Capital expenditures are expected to approximate $4.3 billion for the year 2026, including $3.0 billion for major mining projects. Projected capital expenditures for major mining projects include $1.4 billion for planned projects, primarily associated with underground mine development and supporting mill and power capital costs in the Grasberg minerals district and a leaching project at El Abra, and $1.6 billion for discretionary growth projects.

In May 2026, FCX entered into a new $3.0 billion, five-year senior unsecured revolving credit facility that matures in May 2031, which replaced its prior revolving credit facility, and Cerro Verde entered into a new $350 million, five-year, senior unsecured revolving credit facility that matures in May 2031, which replaced its prior revolving credit facility. The terms of the new facilities are substantially similar to FCX's and Cerro Verde's respective prior facilities.

At June 30, 2026, there were (i) no borrowings and $5 million in letters of credit issued under FCX’s $3.0 billion revolving credit facility, (ii) $250 million in borrowings outstanding under PTFI’s $1.75 billion revolving credit facility, and (iii) no borrowings outstanding under Cerro Verde’s $350 million revolving credit facility.

FCX’s consolidated debt has an average remaining duration of approximately eight years. PTFI has $0.7 billion in scheduled senior note maturities in April 2027, and FCX has $0.6 billion in scheduled senior note maturities in the second half of 2027.

FINANCIAL POLICY

FCX’s financial policy is aligned with its strategic objectives of maintaining a solid balance sheet, providing cash returns to common stockholders and advancing opportunities for future growth. The policy includes a base dividend and a performance-based payout framework, whereby up to 50% of available cash flows generated after planned capital spending and distributions to noncontrolling interests would be allocated to common stockholder returns and the balance to debt reduction and investments in value enhancing growth projects, subject to FCX maintaining its net debt at a level not to exceed the net debt target of $3.0 billion to $4.0 billion (excluding project debt for PTFI’s downstream processing facilities). FCX’s Board of Directors (Board) reviews the structure of the performance-based payout framework at least annually.

Net Debt. At June 30, 2026, FCX’s net debt totaled $2.1 billion, which excludes $3.2 billion of debt for PTFI’s downstream processing facilities. Refer to the supplemental schedule, “Net Debt,” on page IX.

Common Stock Dividends. On June 24, 2026, FCX’s Board declared cash dividends totaling $0.15 per share on its common stock (including a $0.075 per share quarterly base cash dividend and a $0.075 per share quarterly variable, performance-based cash dividend), which will be paid on August 3, 2026, to common stockholders of record as of July 15, 2026. The declaration and payment of dividends (base or variable) are at the

discretion of the Board and will depend on FCX’s financial results, cash requirements, global economic conditions and other factors deemed relevant by the Board.

Share Repurchase Program. During second-quarter 2026, FCX purchased 1.7 million shares of its common stock for a total cost of $110 million ($64.34 average cost per share) bringing total purchases during the first six months of 2026 to 3.4 million shares for a total cost of $203 million ($59.30 average cost per share).

As of July 22, 2026, FCX has 1.4 billion shares of common stock outstanding and has purchased 55.4 million shares for a total cost of $2.2 billion ($39.80 average cost per share) under its $5.0 billion share repurchase program. The timing and amount of share repurchases is at the discretion of management and will depend on a variety of factors. The share repurchase program may be modified, increased, suspended or terminated at any time at the Board’s discretion.

CONFERENCE CALL

A conference call with securities analysts to discuss FCX’s second-quarter 2026 results is scheduled for today at 10:00 a.m. Eastern Time. The conference call will be broadcast on the internet along with slides. Interested parties may listen to the conference call live and view the slides by accessing fcx.com.

FREEPORT: Foremost in Copper

FCX is a leading international metals company with the objective of being foremost in copper. Headquartered in Phoenix, Arizona, FCX operates large, long-lived, geographically diverse assets with significant proven and probable reserves of copper, gold and molybdenum.

Forward-looking statements are all statements other than statements of historical facts, such as plans, projections or expectations relating to business outlook, strategy, goals or targets; restoration and remediation efforts, and phased restart and ramp-up of production and downstream processing following the September 2025 external mud rush incident at PTFI’s Grasberg Block Cave underground mine and the anticipated impact on FCX’s business, production, sales, results of operations and operating plans; global market conditions, including trade policies; ore grades and milling rates; production and sales volumes; higher variability between PTFI production and sales; unit net cash costs (credits) and operating costs; capital expenditures; operating plans, including mine sequencing; cash flows; liquidity; the life of resource extension of operating rights in the Grasberg minerals district, including the extension of PTFI’s IUPK beyond 2041; timing of shipments of inventoried production; FCX’s sustainability-related commitments, aspirations and targets; FCX’s overarching commitment to deliver responsibly produced copper and molybdenum, including plans to implement, validate and maintain validation of its operating sites under specific frameworks; achievement of FCX’s 2030 climate targets and its 2050 net zero aspiration; improvements in operating procedures and technology innovations and applications; exploration efforts and results; development and production activities, rates and costs; future organic growth opportunities and investment decisions; tax rates; the impact of copper, gold and molybdenum price changes; the impact of deferred intercompany profits on earnings; mineral reserve and mineral resource estimates; final resolution of settlements associated with ongoing legal and environmental proceedings; debt repurchases; and the ongoing implementation of FCX’s financial policy and future returns to common stockholders, including dividend payments (base or variable) and share repurchases.

The words “anticipates,” “may,” “can,” “plans,” “believes,” “estimates,” “expects,” “projects,” “targets,” “intends,” “likely,” “will,” “should,” “could,” “to be,” “potential,” “assumptions,” “guidance,” “aspirations,” “future,” “commitments,” “pursues,” “initiatives,” “objectives,” “opportunities,” “strategy” and any similar expressions are intended to identify those assertions as forward-looking statements. The declaration and payment of dividends (base or variable), and timing and amount of any share repurchases are at the discretion of the Board and management, respectively, and are subject to a number of factors, including not exceeding FCX’s net debt target, capital availability, FCX’s financial results, cash requirements, global economic conditions, changes in laws, contractual restrictions and other factors deemed relevant by the Board or management, as applicable. The share repurchase program may be modified, increased, suspended or terminated at any time at the Board’s discretion.

FCX cautions readers that forward-looking statements are not guarantees of future performance and actual results may differ materially from those anticipated, expected, projected or assumed in the forward-looking statements. Important factors that can cause FCX’s actual results to differ materially from those anticipated in the forward-looking statements include, but are not limited to, supply of and demand for, and prices of the commodities FCX produces, primarily copper and gold; changes in export duties and tariff rates; production rates; timing of shipments and sales; reduced customer demand or capacity; changes in the terms of arrangements or contracts; PTFI’s ability to repair mud rush incident-related damage, implement enhanced operating procedures, safely restart with a phased ramp-up and achieve full operating rates of production and downstream processing on the expected timeline and optimize production plans; resolve force majeure declarations and maintain relationships with commercial counterparties; price and availability of consumables and components FCX purchases as well as constraints on supply and logistics, and transportation services; changes in cash requirements, financial position, financing or investment plans; changes in general market, economic, geopolitical, regulatory or industry conditions, including market volatility regarding trade policies and tariff

uncertainty; reductions in liquidity and access to capital; changes in tax laws and regulations; political and social risks, including the potential effects of violence in Indonesia, civil unrest in Peru, and relations with local communities and Indigenous Peoples; operational risks inherent in mining, with higher inherent risks in underground mining; mine sequencing; changes in mine plans or operational modifications, delays, deferrals or cancellations, including the ability to smelt and refine or inventory; results of technical, economic or feasibility studies; potential inventory adjustments; potential impairment of long-lived mining assets; satisfaction of requirements in accordance with PTFI’s IUPK to extend mining rights from 2031 through 2041; delays in Indonesia government approvals or failure to obtain Indonesia government approval, including on the agreed upon terms of the MOU and relating to the amendment to the IUPK to extend PTFI’s operating rights beyond 2041; delays in consummating the terms of the MOU, including entering into any definitive agreements; cybersecurity risks; any major public health crisis; labor relations, including labor-related work stoppages and increased costs; compliance with applicable environmental, health and safety laws and regulations; weather- and climate-related risks; environmental risks, including availability of secure water supplies; impacts, expenses or results from litigation or investigations; tailings management; FCX’s ability to comply with its responsible production commitments under specific frameworks and any changes to such frameworks and other factors described in more detail under the heading “Risk Factors” in FCX’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the U.S. Securities and Exchange Commission.

Investors are cautioned that many of the assumptions upon which FCX’s forward-looking statements are based are likely to change after the date the forward-looking statements are made, including for example commodity prices, which FCX cannot control, and production volumes and costs or technological solutions and innovations, some aspects of which FCX may not be able to control. Further, FCX may make changes to its business plans that could affect its results. FCX undertakes no obligation to update any forward-looking statements, which are as of the date made, notwithstanding any changes in its assumptions, changes in business plans, actual experience or other changes.

This press release also contains measures such as net debt, adjusted net income and unit net cash costs (credits) per pound of copper and molybdenum, which are not recognized under U.S. generally accepted accounting principles (GAAP). Reconciliations of these non-GAAP measures to amounts reported in FCX’s consolidated financial statements are in the supplemental schedules of this press release. For forward-looking unit net cash costs (credits) per pound of copper and molybdenum measures, FCX is unable to provide a reconciliation to the most comparable GAAP measure without unreasonable effort because estimating such GAAP measures and providing a meaningful reconciliation is extremely difficult and requires a level of precision that is unavailable for these future periods, and the information needed to reconcile these measures is dependent upon future events, many of which are outside of FCX’s control as described above. Forward-looking non-GAAP measures are estimated consistent with the relevant definitions and assumptions.

Assuming achievement of current sales volume and cost estimates and prices of $6.00 per pound for copper, $4,000 per ounce for gold and $30.00 per pound for molybdenum for the second half of 2026, FCX estimates its consolidated effective tax rate for the year 2026 would approximate 30%, including estimated effective rates of 40% for Peru, 36% for Indonesia and 7% for the U.S. (associated with CAMT provisions). Changes in projected sales volumes, commodity prices, and the relative proportion of jurisdictional income during the second half of 2026 could impact FCX’s consolidated effective tax rate for the year 2026.

NET DEBT

FCX believes that net debt provides investors with information related to the performance-based payout framework in its financial policy, which requires FCX to maintain its net debt at a level not to exceed the net debt target of $3 billion to $4 billion (excluding project debt for PTFI’s downstream processing facilities). FCX defines net debt as consolidated debt less consolidated cash and cash equivalents. This information differs from consolidated debt determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for consolidated debt determined in accordance with U.S. GAAP. FCX’s net debt, which may not be comparable to similarly titled measures reported by other companies, follows (in millions):

DERIVATIVE INSTRUMENTS

For the six months ended June 30, 2026, FCX’s mined copper was sold 38% as cathode, 35% as rod, and 27% in concentrate. All of FCX’s copper concentrate and some cathode sales contracts provide final copper pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted London Metal Exchange (LME) monthly average settlement copper prices. FCX records revenues and invoices customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement.

FCX’s average realized copper price was $6.17 per pound in second-quarter 2026, reflecting copper sales from South America and Indonesia operations that are generally based on quoted LME monthly average settlement copper prices, which averaged $6.05 per pound in second-quarter 2026, and copper sales from U.S. copper mines that are generally based on prevailing Commodity Exchange Inc. (COMEX) monthly average settlement copper prices, which averaged $6.16 per pound in second-quarter 2026.
