General Information [Abstract]
General Information	GENERAL INFORMATION The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by generally accepted accounting principles in the United States (U.S.). Therefore, this information should be read in conjunction with Freeport-McMoRan Inc.’s (FCX) consolidated financial statements and notes contained in its annual report on Form 10-K for the year ended December 31, 2022 (2022 Form 10-K). The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. All such adjustments are, in the opinion of management, of a normal recurring nature. Operating results for the three-month period ended March 31, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. PT Freeport Indonesia (PT-FI). Beginning January 1, 2023, FCX’s economic ownership interest in PT-FI is 48.76% and prior to January 1, 2023, FCX’s economic interest in PT-FI approximated 81%. As discussed in Note 3 of FCX’s 2022 Form 10-K, in accordance with provisions pertaining to PT-FI’s shareholders agreement, FCX's first-quarter 2023 net income included a $35 million net benefit associated with PT-FI sales volumes that were attributed to FCX at its previous approximate 81% economic ownership interest. Subsequent Events. FCX evaluated events after March 31, 2023, and through the date the consolidated financial statements were issued and determined any events and transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these consolidated financial statements.

Earnings per Share	Mar. 31, 2023
Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE FCX calculates its basic net income per share of common stock under the two-class method and calculates its diluted net income per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income per share of common stock was computed by dividing net income attributable to common stockholders (after deducting accumulated dividends and undistributed earnings to participating securities) by the weighted-average shares of common stock outstanding during the period. Diluted net income per share of common stock was calculated by including the basic weighted-average shares of common stock outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be antidilutive. Reconciliations of net income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted net income per share follow (in millions, except per share amounts): Three Months Ended March 31, 2023 2022 Net income $ 1,049 $ 1,904 Net income attributable to noncontrolling interests (386) (377) Undistributed dividends and earnings allocated to participating securities (5) (5) Net income attributable to common stockholders $ 658 $ 1,522 Basic weighted-average shares of common stock outstanding 1,433 1,455 Add shares issuable upon exercise or vesting of dilutive stock options and restricted stock units (RSUs) 10 14 Diluted weighted-average shares of common stock outstanding 1,443 1,469 Basic net income per share attributable to common stockholders $ 0.46 $ 1.05 Diluted net income per share attributable to common stockholders $ 0.46 $ 1.04 Shares associated with outstanding stock options with exercise prices greater than the average market price of FCX’s common stock during the period are excluded from the computation of diluted net income per share of common stock. There were no shares of common stock associated with outstanding stock options excluded in first-quarter 2023 and 2 million shares associated with outstanding stock options excluded in first-quarter 2022.

The increase in finished goods inventory at March 31, 2023, was associated with the change in PT-FI's commercial arrangement with PT Smelting (PT-FI’s 39.5% owned copper smelter and refinery in Gresik, Indonesia) from a concentrate sales agreement to a tolling arrangement beginning on January 1, 2023. As a result of the arrangement, a portion of PT-FI’s first-quarter 2023 production was deferred in inventory and will be sold as refined metal in future periods. c. Estimated metals in stockpiles not expected to be recovered within the next 12 months.

Income Taxes	INCOME TAXES Geographic sources of FCX’s benefit (provision) for income taxes follow (in millions): Three Months Ended March 31, 2023 2022 U.S. operations $ 4 $ (3) International operations (503) (821) Total $ (499) $ (824) FCX’s consolidated effective income tax rate was 32% for first-quarter 2023 and 30% for first-quarter 2022. Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. Because of its U.S. tax position, FCX does not record a financial statement impact for income or losses generated in the U.S. In August 2022, the U.S. Inflation Reduction Act of 2022 (Act) was signed into law, which includes, among other provisions, a new Corporate Alternative Minimum Tax (CAMT) of 15% on the adjusted financial statement income (AFSI) of corporations with average AFSI exceeding $1.0 billion over a three-year period. The provisions of the Act became applicable to FCX on January 1, 2023. As limited guidance related to how the CAMT provisions of the Act should be applied or otherwise administered has been released by the U.S. Department of the Treasury (Treasury), uncertainty remains regarding the application of the CAMT. FCX has made interpretations of certain provisions of the Act, and based on these interpretations, determined that the provisions of the Act did not impact FCX’s first-quarter 2023 financial results. However, future guidance released by the Treasury may differ from FCX’s interpretations, which could be material and could further limit FCX’s ability to realize future benefits from its U.S. net operating losses.

FCX and PT-FI have a $3.0 billion, unsecured revolving credit facility that matures in October 2027. Under the terms of the revolving credit facility, FCX may obtain loans and issue letters of credit in an aggregate amount of up to $3.0 billion with PT-FI’s capacity limited to $500 million, and letters of credit issuance limited to $1.5 billion. At March 31, 2023, FCX had $8 million in letters of credit issued under its revolving credit facility. PT-FI has a $1.3 billion unsecured revolving credit facility that matures in July 2026. Cerro Verde has a $350 million unsecured revolving credit facility that matures in May 2027. At March 31, 2023, FCX, PT-FI and Cerro Verde had no borrowings outstanding under their respective revolving credit facilities and were in compliance with their respective covenants. Senior Notes. In March 2023, FCX repaid in full the outstanding principal balance of its 3.875% Senior Notes totaling $996 million at maturity. Interest Expense, Net. Consolidated interest costs (before capitalization) totaled $207 million in first-quarter 2023 and $153 million in first-quarter 2022. The increase in consolidated interest costs (before capitalization) is primarily related to interest associated with PT-FI’s $3.0 billion of senior notes that were issued in April 2022 and a charge of $25 million related to contested tax matters in Peru. Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $56 million in first-quarter 2023 and $26 million in first-quarter 2022. The increase in capitalized interest costs resulted from increased construction and development projects in process, primarily at the Manyar smelter and precious metals refinery in Indonesia (collectively, the Indonesia smelter projects). Share Repurchase Program and Dividends. Since mid-2021, FCX has acquired 47.8 million shares of its common stock under the share repurchase program for a total cost of $1.8 billion ($38.35 average cost per share), including 12.3 million shares in first-quarter 2022 for a cost of $541 million. No shares have been purchased since July 11, 2022. As of May 4, 2023, FCX has $3.2 billion available for repurchases under the program. On March 22, 2023, FCX declared quarterly cash dividends totaling $0.15 per share ($0.075 per share base dividend and $0.075 per share variable dividend) on its common stock, which were paid on May 1, 2023, to common stockholders of record as of April 14, 2023. The declaration and payment of dividends (base or variable) and timing and amount of any share repurchases are at the discretion of FCX’s Board of Directors (Board) and management, respectively, and are subject to a number of factors, including maintaining 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 FCX’s Board or management, as applicable. FCX’s share repurchase program may be modified, increased, suspended or terminated at any time at the Board’s discretion.

Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS FCX does not purchase, hold or sell derivative financial instruments unless there is an existing asset or obligation, or it anticipates a future activity that is likely to occur and will result in exposure to market risks, which FCX intends to offset or mitigate. FCX does not enter into any derivative financial instruments for speculative purposes but has entered into derivative financial instruments in limited instances to achieve specific objectives. These objectives principally relate to managing risks associated with commodity price changes, foreign currency exchange rates and interest rates. Commodity Contracts. From time to time, FCX has entered into derivative contracts to hedge the market risk associated with fluctuations in the prices of commodities it purchases and sells. Derivative financial instruments used by FCX to manage its risks do not contain credit risk-related contingent provisions. A discussion of FCX’s other derivative contracts and programs follows. Derivatives Designated as Hedging Instruments - Fair Value Hedges Copper Futures and Swap Contracts. Some of FCX’s U.S. copper rod and cathode customers request a fixed market price instead of the Commodity Exchange Inc. (COMEX) average copper price in the month of shipment. FCX hedges this price exposure in a manner that allows it to receive the COMEX average price in the month of shipment while the customers pay the fixed price they requested. FCX accomplishes this by entering into copper futures or swap contracts. Hedging gains or losses from these copper futures and swap contracts are recorded in revenues. FCX did not have any significant gains or losses resulting from hedge ineffectiveness during the three-month periods ended March 31, 2023 and 2022. At March 31, 2023, FCX held copper futures and swap contracts that qualified for hedge accounting for 96 million pounds at an average contract price of $3.94 per pound, with maturities through December 2024. A summary of gains (losses) recognized in revenues for derivative financial instruments related to commodity contracts that are designated and qualify as fair value hedge transactions, including on the related hedged item follows (in millions): Three Months Ended March 31, 2023 2022 Copper futures and swap contracts: Unrealized gains (losses): Derivative financial instruments $ 14 $ 12 Hedged item – firm sales commitments (14) (12) Realized gains: Matured derivative financial instruments 8 14 Derivatives Not Designated as Hedging Instruments Embedded Derivatives. Certain FCX concentrate, copper cathode and gold sales contracts provide for provisional pricing primarily based on the London Metal Exchange (LME) copper price or the COMEX copper price and the London Bullion Market Association (London) gold price at the time of shipment as specified in the contract. FCX receives market prices based on prices in the specified future month, which results in price fluctuations recorded in revenues until the date of settlement. FCX records revenues and invoices customers at the time of shipment based on then-current LME or COMEX copper prices and the London gold price as specified in the contracts, which results in an embedded derivative ( i.e. , a pricing mechanism that is finalized after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale of the metals contained in the concentrate or cathode at the then-current LME or COMEX copper price, and the London gold price. FCX applies the normal purchases and normal sales scope exception in accordance with derivatives and hedge accounting guidance to the host contract in its concentrate or cathode sales agreements since these contracts do not allow for net settlement and always result in physical delivery. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through earnings each period, using the period-end LME or COMEX copper forward prices and the adjusted London gold price, until the date of final pricing. Similarly, FCX purchases copper under contracts that provide for provisional pricing. Mark-to-market price fluctuations from these embedded derivatives are recorded through the settlement date and are reflected in revenues for sales contracts and in inventory for purchase contracts. A summary of FCX’s embedded derivatives at March 31, 2023, follows: Open Positions Average Price Maturities Through Contract Market Embedded derivatives in provisional sales contracts: Copper (millions of pounds) 547 $ 3.92 $ 4.08 August 2023 Gold (thousands of ounces) 199 1,876 1,991 June 2023 Embedded derivatives in provisional purchase contracts: Copper (millions of pounds) 78 4.01 4.06 August 2023 Copper Forward Contracts. Atlantic Copper, FCX’s wholly owned smelting and refining unit in Spain, enters into copper forward contracts designed to hedge its copper price risk whenever its physical purchases and sales pricing periods do not match. These economic hedge transactions are intended to hedge against changes in copper prices, with the mark-to-market hedging gains or losses recorded in production and delivery costs. At March 31, 2023, Atlantic Copper held net copper forward sales contracts for 12 million pounds at an average contract price of $4.01 per pound, with maturities through May 2023. Summary of Gains (Losses). A summary of the realized and unrealized gains (losses) recognized in operating income for commodity contracts that do not qualify as hedge transactions, including embedded derivatives, follows (in millions): Three Months Ended March 31, 2023 2022 Embedded derivatives in provisional sales contracts: a Copper $ 231 $ 218 Gold and other metals 42 22 Copper forward contracts b (2) 4 a.

FCX’s embedded derivatives on provisional sales/purchase contracts are netted with the corresponding outstanding receivable/payable balances. A summary of these unsettled commodity contracts that are offset in the balance sheet follows (in millions): Assets Liabilities March 31, December 31, 2022 March 31, December 31, 2022 Gross amounts recognized: Commodity contracts: Embedded derivatives in provisional sales/purchase contracts $ 119 $ 166 $ 10 $ 39 Copper derivatives 15 4 1 3 134 170 11 42 Less gross amounts of offset: Commodity contracts: Embedded derivatives in provisional sales/purchase contracts 3 — 3 — 3 — 3 — Net amounts presented in balance sheet: Commodity contracts: Embedded derivatives in provisional sales/purchase contracts 116 166 7 39 Copper derivatives 15 4 1 3 $ 131 $ 170 $ 8 $ 42 Balance sheet classification: Trade accounts receivable $ 108 $ 163 $ 3 $ 7 Other current assets 15 4 — — Accounts payable and accrued liabilities 8 3 5 34 Other liabilities — — — 1 $ 131 $ 170 $ 8 $ 42 Credit Risk. FCX is exposed to credit loss when financial institutions with which it has entered into derivative transactions (commodity, foreign exchange and interest rate swaps) are unable to pay. To minimize the risk of such losses, FCX uses counterparties that meet certain credit requirements and periodically reviews the creditworthiness of these counterparties. As of March 31, 2023, the maximum amount of credit exposure associated with derivative transactions was $134 million. Other Financial Instruments. Other financial instruments include cash, cash equivalents, restricted cash and cash equivalents, accounts receivable, investment securities, legally restricted trust assets, accounts payable and accrued liabilities, accrued income taxes, dividends payable and debt. The carrying value for these financial instruments classified as current assets or liabilities approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 7 for the fair values of investment securities, legally restricted funds and debt). In addition, as of March 31, 2023, FCX has contingent consideration assets related to the sales of certain oil and gas properties (refer to Note 7 for the related fair values). Cash, Cash Equivalents and Restricted Cash and Cash Equivalents. The following table provides a reconciliation of total cash, cash equivalents and restricted cash and cash equivalents presented in the consolidated statements of cash flows (in millions): March 31, December 31, 2022 Balance sheet components: Cash and cash equivalents a,b $ 6,852 $ 8,146 Restricted cash and cash equivalents included in: Other current assets 118 111 Other assets 134 133 Total cash, cash equivalents and restricted cash and cash equivalents presented in the consolidated statements of cash flows $ 7,104 $ 8,390 a.

Fair Value Disclosures [Abstract]
Fair Value Measurement	FAIR VALUE MEASUREMENT Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). FCX did not have any significant transfers in or out of Level 3 during first-quarter 2023. FCX’s financial instruments are recorded on the consolidated balance sheets at fair value except for contingent consideration associated with the sale of the Deepwater Gulf of Mexico (GOM) oil and gas properties (which was recorded under the loss recovery approach) and debt. A summary of the carrying amount and fair value of FCX’s financial instruments (including those measured at net asset value (NAV) as a practical expedient), other than cash, cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, accrued income taxes and dividends payable (refer to Note 6) follows (in millions): At March 31, 2023 Carrying Fair Value Amount Total NAV Level 1 Level 2 Level 3 Assets Investment securities: a,b U.S. core fixed income fund $ 26 $ 26 $ 26 $ — $ — $ — Equity securities 7 7 — 7 — — Total 33 33 26 7 — — Legally restricted funds: a U.S. core fixed income fund 63 63 63 — — — Government mortgage-backed securities 38 38 — — 38 — Government bonds and notes 32 32 — — 32 — Corporate bonds 31 31 — — 31 — Money market funds 21 21 — 21 — — Asset-backed securities 19 19 — — 19 — Collateralized mortgage-backed securities 2 2 — — 2 — Total 206 206 63 21 122 — Derivatives: c Embedded derivatives in provisional sales/purchase contracts in a gross asset position 119 119 — — 119 — Copper futures and swap contracts 15 15 — 14 1 — Total 134 134 — 14 120 — Contingent consideration for the sale of the Deepwater GOM oil and gas properties a 63 54 — — — 54 Liabilities Derivatives: c Embedded derivatives in provisional sales/purchase contracts in a gross liability position 10 10 — — 10 — Copper forward contracts 1 1 — — 1 — Total 11 11 — — 11 — Long-term debt, including current portion d 9,635 9,336 — — 9,336 — At December 31, 2022 Carrying Fair Value Amount Total NAV Level 1 Level 2 Level 3 Assets Investment securities: a,b U.S. core fixed income fund $ 25 $ 25 $ 25 $ — $ — $ — Equity securities 7 7 — 7 — — Total 32 32 25 7 — — Legally restricted funds: a U.S. core fixed income fund 56 56 56 — — — Government mortgage-backed securities 37 37 — — 37 — Government bonds and notes 34 34 — — 34 — Corporate bonds 31 31 — — 31 — Asset-backed securities 17 17 — — 17 — Money market funds 3 3 — 3 — — Collateralized mortgage-backed securities 3 3 — — 3 — Total 181 181 56 3 122 — Derivatives: c Embedded derivatives in provisional sales/purchase contracts in a gross asset position 166 166 — — 166 — Copper futures and swap contracts 3 3 — 3 — — Copper forward contracts 1 1 — 1 — — Total 170 170 — 4 166 — Contingent consideration for the sale of the Deepwater GOM oil and gas properties a 67 57 — — — 57 Liabilities Derivatives: c Embedded derivatives in provisional sales/purchase contracts in a gross liability position 39 39 — — 39 — Copper forward contracts 3 3 — — 3 — Total 42 42 — — 42 — Long-term debt, including current portion d 10,620 10,097 — — 10,097 — a.

Excludes time deposits (which approximated fair value) included in (i) other current assets of $118 million at both March 31, 2023, and December 31, 2022, and (ii) other assets of $133 million at both March 31, 2023, and December 31, 2022, primarily associated with an assurance bond to support PT-FI’s commitment for additional domestic smelter development in Indonesia and PT-FI’s closure and reclamation guarantees. c. Refer to Note 6 for further discussion and balance sheet classifications. d. Recorded at cost except for debt assumed in acquisitions, which are recorded at fair value at the respective acquisition dates. Valuation Techniques. The U.S. core fixed income fund is valued at NAV. The fund strategy seeks total return consisting of income and capital appreciation primarily by investing in a broad range of investment-grade debt securities, including U.S. government obligations, corporate bonds, mortgage-backed securities, asset-backed securities and money market instruments. There are no restrictions on redemptions (which are usually within one business day of notice). Equity securities are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy. Fixed income securities (government securities, corporate bonds, asset-backed securities and collateralized mortgage-backed securities) are valued using a bid-evaluation price or a mid-evaluation price. These evaluations are based on quoted prices, if available, or models that use observable inputs and, as such, are classified within Level 2 of the fair value hierarchy. Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. FCX’s embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales are valued using quoted monthly LME or COMEX copper forward prices and the adjusted London gold price at each reporting date based on the month of maturity (refer to Note 6 for further discussion); however, FCX’s contracts themselves are not traded on an exchange. As a result, these derivatives are classified within Level 2 of the fair value hierarchy. FCX’s derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 6 for further discussion). Certain of these contracts are traded on the over-the-counter market and are classified within Level 2 of the fair value hierarchy based on COMEX and LME forward prices. In December 2016, FCX’s sale of its Deepwater GOM oil and gas properties included up to $150 million in contingent consideration that was recorded at the total amount under the loss recovery approach. The contingent consideration is being received over time as cash flows are realized from a third-party production handling agreement for an offshore platform, with the related payments commencing in third-quarter 2018. The contingent consideration included in (i) other current assets totaled $17 million at March 31, 2023, and $20 million at December 31, 2022, and (ii) other assets totaled $46 million at March 31, 2023, and $47 million at December 31, 2022. The fair value of this contingent consideration was calculated based on a discounted cash flow model using inputs that include third-party estimates for reserves, production rates and production timing, and discount rates. Because significant inputs are not observable in the market, the contingent consideration is classified within Level 3 of the fair value hierarchy. Long-term debt, including current portion, is primarily valued using available market quotes and, as such, is classified within Level 2 of the fair value hierarchy. The techniques described above may produce a fair value that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with other market participants, the use of different techniques or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the techniques used at March 31, 2023, as compared with those techniques used at December 31, 2022. A summary of the changes in the fair value of FCX’s Level 3 instrument, contingent consideration for the sale of the Deepwater GOM oil and gas properties, during the first three months of 2023 follows (in millions): Fair value at January 1, 2023 $ 57 Net unrealized gain related to assets still held at the end of the period 1 Settlements (4) Fair value at March 31, 2023 $ 54

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	CONTINGENCIES AND COMMITMENTS Litigation There were no significant updates to previously reported legal proceedings included in Note 12 of FCX’s 2022 Form 10-K, other than the matter discussed below. Louisiana Parishes Coastal Erosion Cases. Certain FCX affiliates were named as defendants, along with numerous co-defendants, in 13 cases out of a total of 42 cases filed in Louisiana state courts by 6 south Louisiana parishes (Cameron, Jefferson, Plaquemines, St. Bernard, St. John the Baptist and Vermilion), alleging that certain oil and gas exploration and production operations and sulfur mining and production operations in coastal Louisiana contaminated and damaged coastal wetlands and caused significant land loss along the Louisiana coast. In 2019, affiliates of FCX reached an agreement in principle to settle all 13 cases and, as of October 2022, all parties have executed the settlement agreement. On March 16, 2023, a non-plaintiff coastal parish included in the settlement (Terrebonne), filed an amended petition titled Terrebonne Parish Consolidated Government vs. Louisiana Department of Natural Resources et al. , Docket No. 185576, in the 32nd Judicial District Court, Terrebonne Parish, State of Louisiana, adding the settling FCX affiliates to a lawsuit that challenges whether Terrebonne Parish is validly bound to the settlement agreement and seeks to have the court declare the settlement void. FCX is evaluating and exploring options to resolve this dispute and will vigorously defend this matter. Other Matters Smelter Development Progress . As disclosed in Note 12 of FCX’s 2022 Form 10-K, in March 2022, PT-FI paid the Indonesia government an administrative fine totaling $57 million related to lack of smelter development in light of the COVID-19 pandemic (first-quarter 2022 included charges of $41 million associated with the administrative fine). Based on PT-FI’s revised smelter construction schedule, PT-FI does not believe any additional fines should be applied and will dispute any attempts by the Indonesia government to levy additional fines, which could be significant. PT-FI Export License. Indonesia regulations require PT-FI and PT Smelting to renew their export licenses annually, subject to review by the Indonesia government every six months, depending on smelter construction progress. In March 2023, PT-FI received an extension of its export license through June 10, 2023. PT-FI's special mining license provides that exports may continue through 2023, subject to force majeure considerations. PT-FI is working with the Indonesia government to obtain approval to continue exports as required for PT-FI’s operations until the Indonesia smelter projects are fully commissioned and reach designed operating conditions. PT-FI Export Duties. In late 2022, PT-FI’s export duty rate declined from 5% to 2.5% as a result of smelter development progress. In March 2023, the Indonesia government verified that construction progress on the Manyar smelter exceeded 50%, allowing PT-FI’s export duties to be eliminated effective March 29, 2023.

Business Segments

Business Segments	Mar. 31, 2023
Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS FCX has organized its mining operations into four primary divisions - North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX’s reportable segments, which include the Morenci and Cerro Verde copper mines, the Grasberg minerals district (Indonesia Mining), the Rod & Refining operations and Atlantic Copper Smelting & Refining. Intersegment sales between FCX’s business segments are based on terms similar to arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums. FCX defers recognizing profits on sales from its mines to other segments, including Atlantic Copper Smelting & Refining and, through December 31, 2022, on 39.5% of PT-FI’s sales to PT Smelting, until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX’s net deferred profits and quarterly earnings. Beginning January 1, 2023, PT-FI's commercial arrangement with PT Smelting converted from a concentrate sales agreement to a tolling arrangement. Under this arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and PT-FI retains title to all products for sale to third parties ( i.e., there are no further sales from PT-FI to PT Smelting). While the new tolling agreement with PT Smelting does not significantly change PT-FI’s economics, it impacted the timing of PT-FI’s first-quarter 2023 sales and working capital requirements, as a portion of PT-FI’s first-quarter 2023 production was deferred in inventory and will be sold as refined metal in future periods. FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level (included in Corporate, Other & Eliminations), whereas foreign income taxes are recorded and managed at the applicable country level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs, along with some selling, general and administrative costs, are not allocated to the operating divisions or individual segments. Accordingly, the following Financial Information by Business Segment reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

Business Segments	BUSINESS SEGMENTS FCX has organized its mining operations into four primary divisions - North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX’s reportable segments, which include the Morenci and Cerro Verde copper mines, the Grasberg minerals district (Indonesia Mining), the Rod & Refining operations and Atlantic Copper Smelting & Refining. Intersegment sales between FCX’s business segments are based on terms similar to arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums. FCX defers recognizing profits on sales from its mines to other segments, including Atlantic Copper Smelting & Refining and, through December 31, 2022, on 39.5% of PT-FI’s sales to PT Smelting, until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX’s net deferred profits and quarterly earnings. Beginning January 1, 2023, PT-FI's commercial arrangement with PT Smelting converted from a concentrate sales agreement to a tolling arrangement. Under this arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and PT-FI retains title to all products for sale to third parties ( i.e., there are no further sales from PT-FI to PT Smelting). While the new tolling agreement with PT Smelting does not significantly change PT-FI’s economics, it impacted the timing of PT-FI’s first-quarter 2023 sales and working capital requirements, as a portion of PT-FI’s first-quarter 2023 production was deferred in inventory and will be sold as refined metal in future periods. FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level (included in Corporate, Other & Eliminations), whereas foreign income taxes are recorded and managed at the applicable country level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs, along with some selling, general and administrative costs, are not allocated to the operating divisions or individual segments. Accordingly, the following Financial Information by Business Segment reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity. Product Revenues. FCX’s revenues attributable to the products it sold for the first quarters of 2023 and 2022 follow (in millions): Three Months Ended March 31, 2023 2022 Copper: Concentrate $ 1,587 $ 2,691 Cathode 1,327 1,435 Rod and other refined copper products 921 1,116 Purchased copper a 204 70 Molybdenum 592 378 Gold 531 811 Other b 133 188 Adjustments to revenues: Treatment charges c (101) (133) Royalty expense d (60) (95) PT-FI export duties e (18) (98) f Revenues from contracts with customers 5,116 6,363 Embedded derivatives g 273 240 Total consolidated revenues $ 5,389 $ 6,603 a.
