Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Tronox Holdings plc (referred to herein as "Tronox", the "Company", "we", "us", or "our") operates titanium-bearing mineral sand mines and beneficiation operations in Australia and South Africa to produce feedstock materials that can be processed into TiO 2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and Ultrafine© titanium dioxide used in certain specialty applications. Our strategy is to be vertically integrated and produce enough feedstock materials to be as self-sufficient as possible in the production of TiO 2 at our nine TiO 2 pigment facilities located in the United States, Australia, Brazil, UK, France, the Netherlands, China and the Kingdom of Saudi Arabia (“KSA”). We believe that vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our coatings and other TiO 2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands creates meaningful quantities of zircon, pig iron and the rare-earth bearing mineral, monazite, which we also supply to customers around the world. We are a public limited company listed on the New York Stock Exchange and are registered under the laws of England and Wales. Basis of Presentation The accompanying condensed consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, considered necessary for a fair statement of its financial position as of September 30, 2024, and its results of operations for the three and nine months ended September 30, 2024 and 2023. Our unaudited condensed consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements, including, among other things, any potential impacts on the economy as a result of macroeconomic conditions, inflationary pressures, political instability, and supply chain disruptions. Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, "Improvements to Reportable Segment Disclosures". The amendment requires additional disclosures by public entities, including those with a single reportable segment, to disclose significant segment expenses and other segment items for each reportable segment. The guidance applies to fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating any incremental disclosures required as a result of this standard. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The amendments in this update apply to all entities that are subject to Topic 740, Income Taxes. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The amendments in this update are effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. We are currently evaluating any incremental disclosures required as a result of this standard.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue We recognize revenue at a point in time when the customer obtains control of the promised products. For most transactions this occurs when products are shipped from our manufacturing facilities or at a later point when control of the products transfers to the customer at a specified destination or time. Contract assets represent our rights to consideration in exchange for products that have transferred to a customer when the right is conditional on situations other than the passage of time. For products that we have transferred to our customers, our rights to the consideration are typically unconditional and only the passage of time is required before payments become due. These unconditional rights are recorded as "Accounts receivable" in the unaudited Condensed Consolidated Balance Sheets. As of September 30, 2024, and December 31, 2023, we did not have any material contract asset balances. Contract liabilities represent our obligations to transfer products to a customer for which we have received consideration from the customer. From time to time, we may receive advance payment from our customers that is accounted for as deferred revenue. Deferred revenue is earned when control of the product transfers to the customer, which is typically within a short period of time from when we received the advanced payment. Contract liability balances as of both September 30, 2024 and December 31, 2023 were less than $1 million. Contract liability balances were reported as “Accounts payable” in the unaudited Condensed Consolidated Balance Sheets. All material contract liabilities as of December 31, 2023 were recognized as revenue in “Net sales” in the unaudited Condensed Consolidated Statements of Operations during the first quarter of 2024. Disaggregation of Revenue We operate under one operating and reportable segment, Tronox. We disaggregate our revenue from contracts with customers by product type and geographic area. We believe this level of disaggregation appropriately depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors and reflects how our business is managed. Net sales to external customers by geographic areas where our customers are located were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 North America $ 212 $ 191 $ 626 $ 584 South and Central America 54 37 151 119 Europe, Middle-East and Africa 332 256 949 858 Asia Pacific 206 178 672 603 Total net sales $ 804 $ 662 $ 2,398 $ 2,164 Net sales from external customers for each similar type of product were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 TiO 2 $ 616 $ 558 $ 1,874 $ 1,729 Zircon 74 33 247 200 Other products 114 71 277 235 Total net sales $ 804 $ 662 $ 2,398 $ 2,164 Other products mainly include pig iron, TiCl 4 and other mining products. During both the nine months ended September 30, 2024 and 2023, our ten largest third-party customers represented 37% of our consolidated net sales. During both the nine months ended September 30, 2024 and 2023, no single customer accounted for 10% of our consolidated net sales.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our operations are conducted through various subsidiaries in a number of countries throughout the world. We have provided for income taxes based upon the tax laws and rates in the countries in which operations are conducted and income is earned. Income before income taxes is comprised of the following: Three Months Ended Nine Months Ended 2024 2023 2024 2023 Income tax provision $ (26) $ (8) $ (82) $ (339) Income (loss) before income taxes $ 1 $ (6) $ 58 $ 81 Effective tax rate 2,600 % (133) % 141 % 419 % Tronox Holdings plc, a U.K. public limited company is the parent company for the business group, and the statutory tax rate in the U.K. at both September 30, 2024 and 2023 was 25%. The statutory rate in the U.K. changed to 25% effective April 1, 2023 and a weighted average of 23.5% was applied for the full year 2023. The effective tax rates for both the three and nine months ended September 30, 2024 and 2023 are impacted by a variety of factors including income and losses in jurisdictions with valuation allowances, non-taxable income and expense items, prior year accruals, and our jurisdictional mix of income at tax rates different than the U.K. statutory rate. At each reporting date, we perform an analysis to determine the likelihood of realizing our deferred tax assets and whether any valuation allowances are required. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. Our analysis takes into consideration all available positive and negative evidence, including prior operating results, the nature and reason for any losses, our forecast of future taxable income, utilization of tax planning strategies, and the dates on which any deferred tax assets are expected to expire. These assumptions and estimates require a significant amount of judgment and are made based on current and projected circumstances and conditions. During the nine months ended September 30, 2024, we identified negative evidence concerning our ability to realize our Brazilian deferred tax assets. This evidence primarily relates to operational losses generated during the current year, a three-year cumulative loss threshold crossed during the quarter, and fluctuating levels of income and expenses which have led to uncertainty regarding the region's ability to generate net income in the foreseeable future. As a result, we recorded a full valuation allowance against Brazil's $16 million in deferred tax assets. We continue to maintain full valuation allowances related to the total net deferred tax assets in Australia and the United Kingdom, as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. Until these valuation allowances are eliminated, future provisions for income taxes for these jurisdictions will include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments. Additionally, we have valuation allowances against specific tax assets in China, South Africa and the United States. The Company currently has no uncertain tax positions recorded. We believe that we have made adequate provisions for income taxes that may be payable with respect to years open for examination or currently under examination. With regard to years under examination, the ultimate outcome is not presently known and, accordingly, adjustments to our provisions may be necessary and/or reclassifications of noncurrent tax liabilities to current may occur in the future. During the year ended December 31, 2023, the United Kingdom enacted legislation consistent with guidance from the Organization for Economic Co-operation and Development ("OECD") for the implementation of the Global Anti-Base Erosion Model Rules (Pillar Two). Additionally, various other jurisdictions have now implemented domestic minimum taxes which are also effective for 2024. Neither the UK multinational top-up tax nor any jurisdiction's domestic minimum tax are expected to have a material impact on our income tax provisions for 2024.

Transfers and Servicing [Abstract]
Accounts Receivable Securitization Program	Accounts Receivable Securitization Program On March 15, 2022, the Company entered into an accounts receivable securitization program (“Securitization Facility”) with a financial institution ("Purchaser"), through our wholly owned special purpose bankruptcy-remote subsidiary Tronox Securitization LLC (“ SPE”). In November 2022, the Securitization Facility was amended (the "First Amendment") to include receivable generated by our wholly-owned Australian operating subsidiaries Tronox Pigment Pty Ltd., Tronox Pigment Bunbury Ltd. and Tronox Mining Australia Ltd. In June 2023, the Company entered into an additional amendment (the “Second Amendment”) to further include receivables generated by our wholly-owned European operating subsidiaries Tronox Pigment Holland BV and Tronox Pigment UK Limited. Neither the facility limit nor the program term were changed as a result of the Second Amendment, which remained at $200 million and November 2025, respectively. In March 2024, we entered into a Securitization Facility technical amendment (the "Third Amendment"), to increase the percentage of certain receivables eligible for sale to the Purchaser. In April 2024, we again amended the Securitization Facility (the "Fourth Amendment"), to increase the facility limit from $200 million to $230 million. As the Company does not maintain effective control over the sold receivables, we derecognize the sold receivables from our unaudited Condensed Consolidated Balance Sheet and classify the cash proceeds as source of cash from operating activities in our unaudited Condensed Consolidated Statement of Cash Flows. The program is structured on a revolving basis under which cash collections from receivables are used to fund additional purchases of receivables at 100% face value, not to exceed the facility limit. As of September 30, 2024 and December 31, 2023, the total value of accounts receivables sold under the Securitization Facility and derecognized from the Company's unaudited Condensed Consolidated Balance Sheet was $230 million and $186 million, respectively. This resulted in the Company recording $5 million within "Accounts payable" on the Condensed Consolidated Balance Sheet at December 31, 2023, as this amount is due to the Purchaser as a result of a periodic decrease in accounts receivable sold to the Purchaser, which was paid in January 2024. There were no corresponding amounts in Accounts Payable as of September 30, 2024. Additionally, at September 30, 2024 and December 31, 2023, we retained approximately $131 million and $129 million, respectively, of unsold receivables which we pledged as collateral for the sold receivables. The following table sets forth a summary of the receivables sold and fees incurred under the program during the related periods: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Cash proceeds from collections reinvested in the program $ 292 $ 238 $ 790 $ 582 Incremental accounts receivables sold 292 238 834 659 Fees incurred 1 4 3 11 8 1 Amounts relate to monthly utilization of the Securitization Facility and are recorded in "Other (expense) income, net" in our unaudited Condensed Consolidated Statement of Operations.

The average effective interest rate on the MGT loan was 6.1% and 6.0% during the nine months ended September 30, 2024 and September 30, 2023, respectively. Long-Term Debt 2024 Term Loan Facility On May 1, 2024, Tronox Finance LLC (the “Borrower”), an indirect subsidiary of Tronox Holdings plc (the “Company”), together with the Company and certain of the Company’s subsidiaries, entered into Amendment No. 4 (the "2024 Amendment") to the Credit Agreement (as defined below) with the term lenders party thereto and HSBC Bank USA, National Association, as Administrative Agent and Collateral Agent. The 2024 Amendment provides the Borrower with a new five-year incremental term loan facility ("the 2024 Term Loan Facility" and the loan thereunder, the "2024 Term Loans") in an aggregate initial principal amount of $741 million under its Amended and Restated Credit Agreement, dated as of March 11, 2021 (as amended through the date hereof, the "Credit Agreement") among the Borrower, the Company, certain of the Company's subsidiaries, the lenders party thereto from time to time and HSBC Bank USA, National Association, as Administrative Agent and Collateral Agent. The 2024 Term Loan Facility was used to refinance in full the Company's outstanding 2022 Term Loan Facility and the 2023 Term Loan Facility. The obligations of the Borrower under the 2024 Term Loan Facility are guaranteed and secured by the same guarantees and liens under the Credit Agreement prior to the effectiveness of the Amendment. The 2024 Term Loan Facility is a separate class of loans under the Credit Agreement, and if the Borrower elects to make an optional payment under the Credit Agreement or is required to make a mandatory prepayment under the Credit Agreement, the Borrower may, in each case, select which class or classes of loans to prepay. The 2024 Term Loan Facility will amortize in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount of the 2024 Term Loan Facility commencing with the second full fiscal quarter after the effective date of the 2024 Term Loan Facility. The final maturity of the 2024 Term Loan Facility will occur on April 4, 2029. The 2024 Term Loan Facility permits amendments thereto whereby individual lenders may extend the maturity date of their outstanding loans upon the Borrower's request without the consent of any other lender, so long as certain conditions are met. The 2024 Term Loan Facility shall bear interest, at the Borrower's option, at either the base rate or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the 2024 Term Loan Facility is 1.75% per annum for base rate loans or 2.75% per annum for SOFR rate loans. The 2024 Term Loan Facility contains the same negative covenants applicable to the term loans outstanding under the Credit Agreement immediately prior to the effectiveness of the Amendment, which covenants, subject to certain limitations, thresholds and exceptions, limit the Company and its restricted subsidiaries to (among other restrictions): incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). 2024-B Term Loan Facility On September 30, 2024, the Borrower (as defined above), together with the Company and certain of the Company's subsidiaries, entered into Amendment No. 6 to the Credit Agreement (as defined above) with the term lenders party thereto and HSBC Bank USA, National Association, as Administrative Agent and Collateral Agent. Amendment No. 6 provides the Borrower with a new seven-year incremental term loan facility (the "2024-B Term Loan Facility") in an aggregate principal amount of $902 million. The proceeds of the 2024-B Term Loan Facility was used to refinance in full all of the outstanding amounts of the existing Term Loan Facility. The obligations of the Borrower under the 2024-B Term Loan Facility are guaranteed and secured by the same guarantees and liens under the Credit Agreement prior to the effectiveness of Amendment No. 6. The 2024-B Term Loan Facility is a separate class of loans under the Credit Agreement, and if the Borrower elects to make an optional payment under the Credit Agreement or is required to make a mandatory prepayment under the Credit Agreement, the Borrower may, in each case, select which class or classes of loans to prepay. The 2024-B Term Loan Facility will amortize in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount of the 2024-B Term Loans commencing with the second full fiscal quarter after the effective date of the 2024-B Term Loan Facility. The final maturity of the 2024-B Term Loan Facility will occur on September 30, 2031. The 2024-B Refinancing Facility permits amendments thereto whereby individual lenders may extend the maturity date of their outstanding loans upon the Borrower’s request without the consent of any other lender, so long as certain conditions are met. The 2024-B Term Loans shall bear interest, at the Borrower’s option, at either the base rate or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the 2024-B Term Loan Facility is 1.5% per annum for base rate loans or 2.5% per annum for SOFR rate loans. The 2024-B Term Loan Facility contains the same negative covenants applicable to the term loans outstanding under the Credit Agreement immediately prior to the effectiveness of Amendment No. 6, which covenants, subject to certain limitations, thresholds and exceptions, limit the Company and its restricted subsidiaries to (among other restrictions): incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). The 2024-B Term Loan Facility also contains the same representations and warranties, affirmative covenants and events of default applicable to the term loans outstanding under the Credit Agreement immediately prior to the effectiveness of Amendment No. 6. If an event of default occurs under the 2024-B Term Loan Facility, then a majority of the lenders through the administrative agent, may (a) declare the 2024-B Term Loan Facility (and all other loans) to be immediately due and payable and/or (b) foreclose on the collateral securing the obligations under the Credit Agreement. As a result of this transaction, we recognized approximately $2 million in "Loss on extinguishment of debt" on the unaudited Condensed Consolidated Statement of Operations for both the three and nine months ended September 30, 2024. RMB Term Loan Facility and RMB Revolving Credit Facility On August 16, 2024, Tronox Minerals Sands Proprietary Limited and Tronox KZN Sands Proprietary Limited, wholly-owned subsidiaries of the Company, entered into Amendment No. 2 (“the Amendment”) and restatement of a credit facility with RMB, that supersedes and replaces the Standard Bank Term Loan Facility and the Standard Bank Revolving Credit Facility in their entirety. The amended credit facility provides the Company with (a) a new five-year term loan facility in an aggregate principal amount of R1.1 billion (approximately $63 million at September 30, 2024 exchange rate) (the "RMB Term Loan Facility") and (b) a new three-year revolving credit facility (the "RMB Revolving Credit Facility") providing an increase of the revolving commitments of R1.2 billion (approximately $70 million at September 30, 2024 exchange rate). The maturity date on the RMB Term Loan Facility and the RMB Revolving Credit Facility is August 16, 2029 and August 16, 2027, respectively. Mandatory capital repayments of R37.5 million (approximately $2 million at September 30, 2024 exchange rate) are scheduled quarterly with the first mandatory repayment starting in March 31, 2025. Both the RMB Term Loan Facility and RMB Revolving Credit Facility shall bear interest at an adjusted JIBAR rate plus an applicable margin. The applicable margin on the RMB Term Loan Facility is 2.35%. The applicable margin on the RMB Revolving Credit Facility is based upon average credit utilization during any interest period. If the revolving credit facility utilization is less than 33%, less than 66% but greater than 33%, or greater than 66%, the applicable margin is 1.95%, 2.10%, and 2.25%, respectively. The RMB Revolving Credit Facility requires the borrower to pay customary agency fees. Short-Term Debt New Cash Flow Revolver On August 15, 2024, the Borrower (as defined above), together with the Company and certain of the Company's subsidiaries, entered into Amendment No. 5 to the Credit Agreement (as defined above) with the revolving lenders party thereto and HSBC Bank USA, National Association, as Administrative Agent and Collateral Agent. Amendment No. 5 provides for a $350 million replacement revolving loan facility (the "New Cash Flow Revolver") which refinances and replaces the Borrower's existing $350 million revolving loan facility (the "Cash Flow Revolver"). The obligations of the Borrower under the New Cash Flow Revolver are guaranteed and secured by the same guarantees and liens under the Credit Agreement prior to the effective date of Amendment No. 5. The New Cash Flow Revolver is a separate class of loans under the Credit Agreement. The maturity date of the New Cash Flow Revolver will occur on the earlier of (a) August 15, 2029 and (b) the Springing Maturity Date. The Springing Maturity Date is defined under the Credit Agreement as the earlier of the date that is 91 days prior to (i) the scheduled maturity date of the Borrower's 2028 term loans if on such date the outstanding amount of 2028 term loans is greater than $200 million, (ii) the scheduled maturity date of the Borrower's 2029 term loans if on such date the outstanding amount of 2029 term loans is greater than $200 million, (iii) the stated maturity date of the Senior Unsecured 2029 if on such date the aggregate outstanding principal amount of the Senior Unsecured 2029 Notes is greater than $200 million, and (iv) the stated maturity date of certain debt-for-borrowed money (excluding debt issued under the Borrower's inside maturity date basket and certain other debt baskets under the Credit Agreement) incurred after the date of Amendment No. 5 if on such date the aggregate outstanding principal amount of such debt-for-borrowed money is greater than $200 million. The New Cash Flow Revolver shall bear interest, at the Borrower's option, at either the base rate or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the New Cash Flow Revolver shall be determined based on the Borrower's first lien net leverage ratio as of the then most recently ended fiscal quarter and shall range from 1.25% to 0.75% per annum for base rate loans or 2.25% to 1.75% per annum for SOFR rate loans. The New Cash Flow Revolver contains substantially the same negative covenants applicable to the existing Cash Flow Revolver, which covenants, subject to certain limitations, thresholds and exceptions, limit the Company and its restricted subsidiaries to (among other restrictions): incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). The New Cash Flow Revolver contains the same springing financial covenant that was applicable to the existing Cash Flow Revolver. The New Cash Flow Revolver also contains substantially the same representations and warranties, affirmative covenants and events of default applicable to the existing Cash Flow Revolver. If an event of default occurs under the New Cash Flow Revolver, then a majority of the lenders acting through the administrative agent, may (a) declare the New Term Loans (and all other loans) to be immediately due and payable and/or (b) foreclose on the collateral securing the obligations under the Credit Agreement. As a result of this transaction, we recorded less than $1 million in "Loss on extinguishment of debt" on the unaudited Condensed Consolidated Statement of Operations for both the three and nine months ended September 30, 2024 RMB Revolving Credit Facility For a description of the RMB Revolving Credit Facility, see details above under " RMB Term Loan Facility and RMB Revolving Credit Facility ". Emirates Revolver In June 2024, the Company entered into an amendment to extend the maturity date of the Emirates Revolver from June 2024 to December 2024. Insurance premium financing In August 2024, the Company entered into a $29 million insurance premium financing agreement with a third-party financing company. The financing balance requires a 37% down payment and will be repaid in monthly installments over 9 months at an 8.6% fixed annual interest rate. As of September 30, 2024, the financing balance was $17 million and is recorded in "Short-term debt" in the Condensed Consolidated Balance Sheet. Debt Covenants As of September 30, 2024, we are in compliance with all financial covenants in our debt facilities.

Derivatives' Impact on the Condensed Consolidated Statement of Operations: The following table summarizes the impact of the Company's derivatives on the unaudited Condensed Consolidated Statement of Operations: Amount of Pre-Tax Gain (Loss) Recognized in Earnings Amount of Pre-Tax Gain (Loss) Recognized in Earnings Revenue Cost of Goods Sold Other (expense) income, net Cost of Goods Sold Other (expense) income, net Three Months Ended September 30, 2024 Three Months Ended September 30, 2023 Derivatives Not Designated as Hedging Instruments Currency Contracts $ — $ — $ (2) $ — $ 2 Derivatives Designated as Hedging Instruments Currency Contracts $ 2 $ — $ — $ — $ — Natural Gas Hedges $ — $ — $ — $ (1) $ — Total Derivatives $ 2 $ — $ (2) $ (1) $ 2 Amount of Pre-Tax Gain (Loss) Recognized in Earnings Amount of Pre-Tax Gain (Loss) Recognized in Earnings Revenue Cost of Goods Sold Other (expense) income, net Cost of Goods Sold Other (expense) income, net Nine Months Ended September 30, 2024 Nine Months Ended September 30, 2023 Derivatives Not Designated as Hedging Instruments Currency Contracts $ — $ — $ (5) $ — $ (2) Derivatives Designated as Hedging Instruments Currency Contracts $ 2 $ — $ — $ (4) $ — Natural Gas Hedges $ — $ (1) $ — $ (4) $ — Total Derivatives $ 2 $ (1) $ (5) $ (8) $ (2) Interest Rate Risk As a result of the 2024 Amendment (discussed in Note 11), the Company noted that the hedged transaction associated with the interest rate swap with a notional value of $200 million (which converted the variable rate to a fixed rate for a portion of the 2022 Term Loan Facility) had changed as the hedged transaction would now convert the variable rate to a fixed rate for a portion of the 2024 Term Loan Facility. There were no amendments to the terms of the $200 million interest rate swap, including the notional value, index rate, or expiration date as a result of the 2024 Amendment. However, given the change in the hedged transaction, we completed a hedge effectiveness test and determined that this hedge instrument continues to be highly effective at achieving offsetting cash flows related to the hedged transaction, enabling us to continue to apply hedge accounting over the remaining term of this hedge relationship. In line with the original maturity date, one of the interest rate swap agreements (notional value of $250 million) expired in September 2024. As a result of this, on September 26, 2024, the Company entered into two new interest-rate swap agreements for a notional of $125 million each with two counterparty banks, for an aggregate notional of $250 million. These new agreements are effective as of September 30, 2024 and will mature on September 30, 2031, in line with the maturity date of the 2024-B Term Loan Facility following Amendment No.6 (discussed in Note 11). The Company has designated these two new hedges as cash flow hedges with the objective of ensuring that the Company continues to achieve the offsetting effect to the interest rate volatility associated with the $250 million portion of the 2024-B Term Loan Facility. Additionally, on September 26, 2024, the counterparty bank associated with one of the existing interest rate swap contracts (notional value of $250 million) novated its rights and obligations in the interest rate swap contracts to a new counterparty. No other terms and conditions of the interest rate swap contract were impacted by this transaction. We also determined that it is probable the new counterparty will perform its obligations under the interest rate swap agreements. However, following the novation, the Company terminated the existing interest rate swap agreement and simultaneously entered into a new interest rate swap agreement with the new counterparty bank with an effective date of September 30, 2024 and expiring on September 30, 2031 (in line with the maturity date of the 2024-B Term Loan Facility). At the time of this change, the Company determined that the interest payments hedged are still probable to occur, therefore, the gains accumulated of $3 million on the previous interest rate swap are being amortized into interest expense through March 11, 2028, the original maturity of the previous term loan agreement. As a result of this transaction, we completed a hedge effectiveness test and determined that this hedge instrument is highly effective at achieving offsetting cash flows related to the hedged transaction, enabling us to apply hedge accounting over the term of the new hedge relationship. As of September 30, 2024, the Company maintains a total of $950 million of interest rate swaps (with $450 million maturing in March 2028 and $500 million maturing in September 2031) with the objective in using the interest-rate swap agreements to add stability to interest expense and to manage the Company's exposure to interest rate movements. These interest rate swaps have been designated as cash flow hedges and involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Fair value gains or losses on these cash flow hedges are recorded in accumulated other comprehensive loss and are subsequently reclassified into interest expense in the same periods during which the hedged transactions affect earnings. At September 30, 2024 and December 31, 2023, the net unrealized loss of $7 million and the unrealized gain of $18 million, respectively, was recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet. For the three and nine months ended September 30, 2024, the amounts recorded in interest expense related to the interest-rate swap agreements were $7 million and $23 million, respectively, of which a gain of approximately $2 million and $5 million, respectively, was reclassified from "Accumulated other comprehensive loss" to interest expense. For the three and nine months ended September 30, 2023, the net amounts recorded in interest expense related to the interest-rate swap agreements were $8 million and $18 million, respectively, of which $2 million for each period was reclassified from "Accumulated other comprehensive loss" to interest expense. Foreign Currency Risk From time to time, we enter into foreign currency contracts used to hedge forecasted third party non-functional currency sales for our South African subsidiaries and forecasted non-functional currency cost of goods sold for our Australian subsidiaries. Historically, we have used a combination of zero-cost collars or forward contracts to reduce the exposure. These foreign currency contracts are designated as cash flow hedges. Changes to the fair value of these foreign currency contracts are recorded as a component of other comprehensive (loss) income, if these contracts remain highly effective, and are recognized in net sales or costs of goods sold in the period in which the forecasted transaction affects earnings or are recognized in other (expense) income, net when the transactions are no longer probable of occurring. As of September 30, 2024, we had notional amounts of 136 million Australian dollars ($94 million at the September 30, 2024 exchange rate) that expire between October 30, 2024 and December 27, 2024 to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates. As of September 30, 2024, we had notional amounts of 915 million South African Rand ($53 million at the September 30, 2024 exchange rate) that expire between October 30, 2024 and December 27, 2024 to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. At September 30, 2024, there was a net unrealized gain of $6 million recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet, which is expected to be fully recognized in earnings over the next twelve months. There were no corresponding amounts as of December 31, 2023. At December 31, 2022, there was an unrealized net loss of $4 million recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet, which was fully recognized in earnings during the nine months ended September 30, 2023. From time to time, we enter into foreign currency contracts for the South African Rand, Australian Dollar, Euro, Pound Sterling, and Saudi Riyal to reduce exposure of our subsidiaries’ balance sheet accounts not denominated in our subsidiaries’ functional currency to fluctuations in foreign currency exchange rates. Historically, we have used forward contracts to reduce the exposure. For accounting purposes, these foreign currency contracts are not considered hedges. The change in fair value associated with these contracts is recorded in “Other (expense) income, net” within the unaudited Condensed Consolidated Statement of Operations and partially offsets the change in value of third party and intercompany-related receivables not denominated in the functional currency of the subsidiary. At September 30, 2024, there was (i) 734 billion South African Rand (or approximately $43 million at September 30, 2024 exchange rate), (ii) 254 million Australian dollars (or approximately $176 million at the September 30, 2024 exchange rate), (iii) 32 million Pound Sterling (or approximately $43 million at the September 30, 2024 exchange rate), (iv) 12 million Euro (or approximately $13 million at the September 30, 2024 exchange rate), and (v) 88 million Saudi Riyal (or approximately $24 million at the September 30, 2024 exchange rate) of notional amounts of outstanding foreign currency contracts. At December 31, 2023, there was (i) 837 million South African Rand (or approximately $49 million at the September 30, 2024 exchange rate), (ii) 153 million Australian dollars (or approximately $106 million at the September 30, 2024 exchange rate), (iii) 45 million Pound Sterling (or approximately $60 million at the September 30, 2024 exchange rate), (iv) 45 million Euro (or approximately $50 million at the September 30, 2024 exchange rate) and (v) 67 million Saudi Riyal (or approximately $18 million at the September 30, 2024 exchange rate) of notional amounts of outstanding foreign currency contracts.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The accounting standards also have established a fair value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value into three broad levels as follows: Level 1 -Quoted prices in active markets for identical assets or liabilities Level 2 -Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly Level 3 -Unobservable inputs based on the Company’s own assumptions Our debt is recorded at historical amounts. The following table presents the fair value of our debt and derivative contracts at both September 30, 2024 and December 31, 2023: September 30, December 31, Asset Liability Asset Liability Term Loan Facility — — — 903 2022 Term Loan Facility — — — 394 2023 Term Loan Facility — — — 351 2024 Term Loan Facility — 743 — — 2024-B Term Loan Facility — 896 — — Standard Bank Term Loan Facility — — — 64 RMB Term Loan Facility — 63 — — Senior Notes due 2029 — 1,005 — 956 Australian Government Loan — 2 — 1 MGT Loan 20 — 25 Interest rate swaps 5 4 18 — Natural gas hedges — — — 1 Foreign currency contracts 9 — 1 1 We determined the fair value of the Term Loan Facility, the 2022 Term Loan Facility, the 2023 Term Loan Facility, the 2024 Term Loan Facility, the 2024-B Term Loan Facility and the Senior Notes due 2029 using quoted market prices, which under the fair value hierarchy is a Level 1 input. We determined the fair value of the Standard Bank Term Loan Facility and the RMB Term Loan Facility utilizing transactions in the listed markets for identical or similar liabilities, which under the fair value hierarchy is a Level 2 input. The fair value of the Australian Government Loan and MGT Loan is based on the contracted amount which is a Level 2 input. We determined the fair value of the foreign currency contracts, natural gas hedges and the interest rate swaps using inputs other than quoted prices in active markets that are observable either directly or indirectly. The fair value hierarchy for the foreign currency contracts, natural gas hedges and interest rate swaps is a Level 2 input. The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and short-term debt approximate fair value due to the short-term nature of these items.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase and Capital Commitments — Includes obligations for purchase requirements of process chemicals, supplies, utilities and services entered into in the ordinary course of business. At September 30, 2024, purchase commitments were $150 million for the remainder of 2024, $283 million for 2025, $225 million for 2026, $197 million for 2027, $323 million for 2028, and $2,518 million thereafter. Letters of Credit —At September 30, 2024, we had outstanding letters of credit and bank guarantees of $145 million, of which $59 million were letters of credit, of which $47 million is related to the sale of Hawkins Point as discussed below, and $86 million were bank guarantees. Amounts for performance bonds were not material. Environmental Matters —It is our policy to record appropriate liabilities for environmental matters when remedial efforts are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. We expect to fund expenditures for these matters from operating cash flows. The timing of cash expenditures depends principally on the timing of remedial investigations and feasibility studies, regulatory approval of cleanup projects, remedial techniques to be utilized and agreements with other parties. Included in these environmental matters is the following: Hawkins Point Plant. Residual waste mud, known as Batch Attack Mud, and a spent sulfuric waste stream were deposited in an onsite repository (the “Batch Attack Lagoon”) at a former TiO2 manufacturing site, Hawkins Point Plant in Baltimore, Maryland, operated by Cristal USA, Inc. from 1954 until 2011. We assumed responsibility for remediation of the Hawkins Point Plant when we acquired the TiO 2 business of Cristal in April 2019. On December 21, 2022, we sold the Hawkins Point Plant to the Maryland Port Administration ("MPA"), a state agency controlled by the Maryland Department of Transportation. Pursuant to the terms of the transaction, MPA became the lead party in developing and implementing appropriate measures to address, treat, control, and mitigate the environmental conditions at the property under the regulatory oversight of the Maryland Department of the Environment ("MDE"). Under MPA ownership, the Hawkins Point Plant will be utilized for storage and beneficial reuse of dredged material from the Port of Baltimore. In exchange for transferring ownership of the site to MPA, Tronox has agreed to make scheduled, annual payments to MPA which together with scheduled, annual contributions from MPA will be used to remediate the property. The sale of the property to MPA did not have a material impact to the Consolidated Statement of Operations. As of September 30, 2024, we have a provision of $41 million included in "Environmental liabilities" in our Condensed Consolidated Balance Sheet for the Hawkins Point Plant consistent with the accounting policy described above. Other Matters —We are subject to a number of other lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of our business, including matters relating to commercial transactions, prior acquisitions and divestitures, including our acquisition of Cristal, employee benefit plans, intellectual property, and environmental, health and safety matters. We recognize a liability for any contingency that is probable of occurrence and reasonably estimable. We continually assess the likelihood of adverse judgments of outcomes in these matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Included in these other matters are the following: UK Health and Safety Matter.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Restricted Share Units (“RSUs”) 2024 Grant - During the nine months ended September 30, 2024, the Company granted both time-based and performance-based awards to certain members of management. A total of 818,203 of time-based awards were granted to management which will vest ratably over a three-year period ending March 5, 2027. A total of 75,748 of time-based awards were granted to non-employee members of the Board which will vest in May 2025. A total of 818,208 of performance-based awards were granted, of which 409,104 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 409,104 of the awards vest based on certain performance metrics of the Company. The non-TSR performance-based awards vest on March 5, 2027 based on the actual 2026 annual return on invested capital (ROIC). Similar to the Company's historical TSR awards granted in prior years, the TSR awards vest based on the Company's three-year TSR versus the peer group performance levels. Given these terms, the TSR metric is considered a market condition for which we used a Monte Carlo simulation to determine the weighted average grant date fair value of $21.70. The following weighted average assumptions were utilized to value the TSR grants: 2024 Dividend yield — % Expected historical volatility 47.9 % Risk free interest rate 4.46 % Expected life (in years) 3 The unrecognized compensation cost associated with all unvested awards at September 30, 2024 was $32 million, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of approximately 1.9 years.

Related Party Transactions [Abstract]
Related Parties	Related Parties Tasnee / Cristal At September 30, 2024, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a subsidiary of Tasnee, owned 37,580,000 shares of Tronox, or a 24% ownership interest. On May 9, 2018, we entered into an Option Agreement with AMIC which is owned equally by Tasnee and Cristal. Under the terms of the Option Agreement, AMIC granted us an option (the “Option”) to acquire 90% of a special purpose vehicle (the “SPV”), to which AMIC’s ownership in a titanium slag smelter facility (the “Slagger”) in The Jazan City for Primary and Downstream Industries in KSA will be contributed together with $322 million of AMIC indebtedness (the “AMIC Debt”). The AMIC Debt would remain outstanding debt of the SPV upon exercise of the Option. The Option may be exercised if the Slagger achieves certain production criteria related to sustained quality and tonnage of slag produced (the “Option Criteria”). Likewise, AMIC may require us to acquire the Slagger on the same terms if the Option Criteria are satisfied. Furthermore, pursuant to the Option Agreement we lent AMIC $125 million for capital expenditures and operational expenses to facilitate the start-up of the Slagger (the “Tronox Loans”). On May 13, 2020, we amended the Option Agreement (the "First Amendment") with AMIC to address circumstances in which the Option Criteria cannot be satisfied. Pursuant to the First Amendment, Tronox has the right to acquire the SPV in exchange for (i) our forgiveness of the Tronox Loans principal and accrued interest thereon, and (ii) the SPV's assumption of $36 million of indebtedness plus accrued interest thereon lent by AMIC to the SPV. Under the First Amendment, the SPV would not assume any of the AMIC Debt. On May 10, 2023, AMIC and Tronox further amended the Option Agreement (the “Second Amendment”). In the Second Amendment the parties acknowledged that the Option expired on May 10, 2023 without being exercised but agreed to continue negotiating until September 30, 2023 (the "Renegotiation Period") as to whether, and under what circumstances, Tronox may acquire the Slagger. Subsequent to September 30, 2023, the parties continued to negotiate as to whether, and under what circumstances, Tronox may acquire the Slagger and on February 21, 2024 the parties again amended the Option Agreement (the “Third Amendment”), which extended the Renegotiation Period until the earlier of the repayment of the Tronox Loans or December 31, 2024, subject to certain early termination rights. The Third Amendment also provided that from the date the parties entered into the Second Amendment and through December 31, 2023, all chloride slag produced by the Slagger was delivered to Tronox as repayment in-kind of the Tronox Loans at a price based on a widely published index for feedstock less a nominal discount (the “Slag Price”). Thereafter and until the end of the Renegotiation Period, 65% of all chloride slag produced by the Slagger will be delivered to Tronox as repayment in-kind of the Tronox Loans based on the Slag Price and Tronox will purchase via cash settlements the remaining 35% at the Slag Price. Full repayment of the Tronox Loans is required by January 2025 in either cash or in-kind through chloride slag deliveries. During July 2023, we also entered into an agreement with AMIC to act as their sales agent with regard to sales of slag fines to customers outside of the Kingdom of Saudi Arabia for an agreed upon commission fee to be paid. The following table shows the outstanding balance of the Tronox Loans, which at September 30, 2024 and December 31, 2023, is recorded on the unaudited Condensed Consolidated Balance Sheet in "Prepaid and other assets" and "Other long-term assets," respectively: September 30, 2024 December 31, 2023 Principal balance 40 80 Accrued interest income balance 8 12 Total outstanding balance 48 92 The following table shows the interest income earned on the Tronox Loans, which is recorded in "Interest income" on our unaudited Condensed Consolidated Statement of Operations: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Interest income — 1 2 4 The following table shows the amount of feedstock purchased from the Slagger, which is subsequently recorded in "Cost of goods sold" on our unaudited Condensed Consolidated Statement of Operations: Three Months Ended Nine Months Ended 2024 2023 2024 2023 Settled as in-kind repayment of Tronox Loans 10 27 40 27 Settled in cash 6 — 22 — Total chloride slag purchases 16 27 62 27 The following table shows the amounts due to AMIC at period-end regarding feedstock purchased from the Slagger, which are recorded in "Accrued liabilities" on our unaudited Condensed Consolidated Balance Sheet: September 30, 2024 December 31, 2023 Amount due to AMIC for slag purchases 5 — In addition, on March 15, 2018 Tronox and AMIC entered into a Technical Services Agreement (the "Original Technical Services Agreement"), which was subsequently amended on May 13, 2020, May 10, 2023 and February 21, 2024 (the "Restated Technical Services Agreement"). Through September 30, 2023 we provided technical advice and project management services, however AMIC and its consultants were still responsible for engineering and construction of the Slagger. As compensation for these services, Tronox received certain fees, including a management fee. In the unaudited Condensed Consolidated Statement of Operations and shown in the table below, the management fees per the Original Technical Services Agreement were recorded within "Other (expense) income, net" and other technical support fees, including fees per the Restated Technical Services Agreement, are recorded within "Selling, general and administrative expenses". From and after October 1, 2023, we no longer receive a management fee and the scope of services we provide is more limited, for which we receive cost reimbursement plus a nominal margin.

Consideration for the acquisition is the assumption by Tronox of a $36 million note payable to Cristal (the "MGT Loan"). MGT is used at a titanium "sponge" plant facility, 65% of the ownership interests of which are held by Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd ("ATTM"), a joint venture between AMIC and Toho Titanium Company Ltd. ATTM uses the TiCl 4 , which we supply by pipeline, for the production of titanium sponge, a precursor material used in the production of titanium metal. On December 17, 2020 we completed the MGT transaction.

Fair Value	Fair Value Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The accounting standards also have established a fair value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value into three broad levels as follows: Level 1 -Quoted prices in active markets for identical assets or liabilities Level 2 -Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly Level 3 -Unobservable inputs based on the Company’s own assumptions
