NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Millions of U.S. dollars, except share, per share and metric tons data or unless otherwise noted)

1.    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 TiO2 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 TiO2 at our nine TiO2 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 TiO2 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 March 31, 2024, and its results of operations for the three months ended March 31, 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

10

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.

2.    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 March 31, 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 March 31, 2024 and December 31, 2023 were $1 million and less than $1 million, respectively. 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.

11

Net sales to external customers by geographic areas where our customers are located were as follows:

	Three Months Ended March 31,
	2024		2023
North America	$	192	$	189
South and Central America	46		42
Europe, Middle-East and Africa	309		282
Asia Pacific	227		195
Total net sales	$	774	$	708

Net sales from external customers for each similar type of product were as follows:

	Three Months Ended March 31,
	2024		2023
TiO2	$	605	$	560
Zircon	88		72
Other products	81		76
Total net sales	$	774	$	708

Other products mainly include pig iron, TiCl4 and other mining products.

During both the three months ended March 31, 2024 and 2023, our ten largest third-party customers represented 37% of our consolidated net sales. During the three months ended March 31, 2024 and 2023, no single customer accounted for 10% of our consolidated net sales.

12

3.    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 March 31,
	2024			2023
Income tax provision	$	(11)		$	(9)
Income before income taxes	$	2		$	34
Effective tax rate	550		%	26		%

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 March 31, 2024 and 2023 was 25% and 19%, respectively. 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 months ended March 31, 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.

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 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.

4.    Income Per Share

The computation of basic and diluted income per share for the periods indicated is as follows:

	Three Months Ended March 31,
	2024		2023
Numerator - Basic and Diluted:
Net (loss) income	$	(9)	$	25
Less: Net income attributable to noncontrolling interest	—		2
Net (loss) income available to ordinary shares	$	(9)	$	23
Denominator - Basic and Diluted:
Weighted-average ordinary shares, basic (in thousands)	157,331		155,175
Weighted-average ordinary shares, diluted (in thousands)	157,331		156,641
Basic net (loss) income per ordinary share	$	(0.06)	$	0.15
Diluted net (loss) income per ordinary share	$	(0.06)	$	0.15

Net (loss) income per ordinary share amounts were calculated from exact, not rounded net (loss) income and share information.  Anti-dilutive shares not recognized in the diluted net income per share calculation for the three months ended March 31, 2024 and 2023 were as follows:

	Shares
	Three Months Ended March 31,
	2024	2023
Options	4,397	265,376
Restricted share units	1,285,008	2,798,108

5.    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. The Fourth Amendment had no impact to financial position or financial results at and for the three months ended March 31, 2024.

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.

14

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 March 31, 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 $200 million and $186 million, respectively. Additionally, at March 31, 2024 and December 31, 2023, we retained approximately $171 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 March 31,
	2024		2023
Cash proceeds from collections reinvested in the program	$	222	$	144
Incremental accounts receivables sold	236		138
Fees incurred1	3		2

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.

6.    Inventories, Net

Inventories, net consisted of the following:

	March 31, 2024		December 31, 2023
Raw materials	$	342	$	352
Work-in-process	141		141
Finished goods, net	682		688
Materials and supplies, net	238		240
Inventories, net	$	1,403	$	1,421

Interest Rate Risk

20

As of March 31, 2024, the Company maintains a total of $950 million of interest rate swaps 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 March 31, 2024 and December 31, 2023, the net unrealized gain of $28 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 months ended March 31, 2024, the amounts recorded in interest expense related to the interest-rate swap agreements were $8 million, of which $2 million for each period was reclassified from "Accumulated other comprehensive loss" to interest expense. For the three months ended March 31, 2023, the net amounts recorded in interest expense related to the interest-rate swap agreements were $4 million.

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 March 31, 2024, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates or to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. 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, of which $2 million was recognized in earnings during the three months ended March 31, 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 March 31, 2024, there was (i) 971 million South African Rand (or approximately $51 million at March 31, 2024 exchange rate), (ii) 138 million Australian dollars (or approximately $90 million at the March 31, 2024 exchange rate), (iii) 48 million Pound Sterling (or approximately $61 million at the March 31, 2024 exchange rate), (iv) 7 million Euro (or approximately $8 million at the March 31, 2024 exchange rate), and (v) 88 million Saudi Riyal (or approximately $23 million at the March 31, 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 $44 million at the March 31, 2024 exchange rate), (ii) 153 million Australian dollars (or approximately $100 million at the March 31, 2024 exchange rate), (iii) 45 million Pound Sterling (or approximately $57 million at the March 31, 2024 exchange rate), (iv) 45 million Euro (or approximately $49 million at the March 31, 2024 exchange rate) and (v) 67 million Saudi Riyal (or approximately $18 million at the March 31, 2024 exchange rate) of notional amounts of outstanding foreign currency contracts.

13.    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

21

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 March 31, 2024 and December 31, 2023:

	March 31, 2024		December 31, 2023
	Asset	Liability	Asset	Liability
Term Loan Facility	—	903	—	903
2022 Term Loan Facility	—	393	—	394
2023 Term Loan Facility	—	350	—	351
Standard Bank Term Loan Facility	—	60	—	64
Senior Notes due 2029	—	966	—	956
Australian Government Loan	—	1	—	1
MGT Loan	—	23	—	25
Interest rate swaps	28	—	18	—
Natural gas hedges	—	1	—	1
Foreign currency contracts	1	—	1	1

We determined the fair value of the Term Loan Facility, the 2022 Term Loan Facility, the 2023 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 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.

14.    Asset Retirement Obligations

Asset retirement obligations consist primarily of rehabilitation and restoration costs, landfill capping costs, decommissioning costs, and closure and post-closure costs. Activities related to asset retirement obligations were as follows:

15.    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 March 31, 2024, purchase commitments were $280 million for the remainder of 2024, $170 million for 2025, $161 million for 2026, $157 million for 2027, $286 million for 2028, and $1,431 million thereafter.

Letters of Credit—At March 31, 2024, we had outstanding letters of credit and bank guarantees of $102 million, of which $63 million were letters of credit, of which $48 million is related to the sale of Hawkins Point as discussed below, and $39 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 TiO2 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 March 31, 2024, we have a provision of $42 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. In February 2024, we received a summons from the UK Health and Safety Executive alleging non-compliance with UK health and safety legislation at the Stallingborough pigment plant resulting from an incident involving an employee in August 2022. Based on our current understanding, we do not believe the enforcement action with regards to this incident will have a material adverse effect on our business, financial condition and results of operations.

Repurchase of Common Stock

On February 21, 2024, in connection with the expiration in February 2024 of the Company's previous share repurchase program, the Company's Board of Directors authorized the repurchase of up to $300 million of the Company's stock through February 21, 2027. During the three months ended March 31, 2024, we made no repurchases of the Company's stock.

17.    Share-Based Compensation

Restricted Share Units (“RSUs”)

2024 Grant - During the three months ended March 31, 2024, the Company granted both time-based and performance-based awards to certain members of management. A total of 806,893 of time-based awards were granted to management which will vest ratably over a three-year period ending March 5, 2027. A total of 806,900 of performance-based awards were granted, of which 403,450 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 403,450 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 $21.68. 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

25

The unrecognized compensation cost associated with all unvested awards at March 31, 2024 was $46 million, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of approximately 2.3 years.

During both the three months ended March 31, 2024 and 2023, we recorded $6 million of stock compensation expense.

18.    Pension and Other Postretirement Healthcare Benefits

For the three months ended March 31, 2024 and 2023, we contributed $1 million and $1 million, respectively, to the Netherlands Multiemployer Plan, which was primarily recognized in “Cost of goods sold” in the unaudited Condensed Consolidated Statement of Operations.

19.    Related Parties

Tasnee / Cristal

At March 31, 2024, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a subsidiary of Tasnee, continues to own 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,

26

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 March 31, 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:

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." 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.

On December 29, 2019, we entered into an agreement with Cristal to acquire certain assets co-located at our Yanbu facility which produces metal grade TiCl4 ("MGT"). 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 TiCl4, 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. Repayment of the $36 million note payable is based on a fixed U.S. dollar amount per metric ton quantity of MGT delivered by us to ATTM over time and therefore the ultimate maturity date is variable in nature. If ATTM fails to purchase MGT from us under certain contractually agreed upon conditions, then at our election we may terminate the MGT supply agreement with ATTM and we will no longer owe any amount under the loan agreement with Cristal. We currently estimate the ultimate maturity to be between approximately four and five years, subject to actual future MGT production levels. The interest rate on the note payable is based on the SAIBOR plus a premium. The note payable is recorded within "Long-term debt, net" and "Long-term debt due within one year" on the unaudited Condensed Consolidated Balance Sheet.

	March 31, 2024	December 31, 2023
Note payable, due within 1 year	7	7
Note payable, due longer than 1 year from now	16	18

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with Tronox Holdings plc’s unaudited condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q, as well as Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2023. This discussion and other sections in this Quarterly Report on Form 10-Q contain forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, that involve risks and uncertainties, and actual results could differ materially from those discussed in the forward-looking statements as a result of numerous factors. Forward-looking statements provide current expectations of future events based on certain assumptions and include any statement that does not directly relate to any historical or current fact. Forward-looking statements also can be identified by words such as “future”, “anticipates”, “believes”, “estimates”, “expects”, “intends”, “plans”, “predicts”, “will”, “would”, “could”, “can”, “may”, and similar terms.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains certain financial measures, in particular the presentation of earnings before interest, taxes, depreciation and amortization (“EBITDA”) and Adjusted EBITDA, which are not presented in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). We are presenting these non-U.S. GAAP financial measures because we believe they provide us and readers of this Form 10-Q with additional insight into our operational performance relative to earlier periods and relative to our competitors. We do not intend for these non-U.S. GAAP financial measures to be a substitute for any U.S. GAAP financial information. Readers of these statements should use these non-U.S. GAAP financial measures only in conjunction with the comparable U.S. GAAP financial measures. A reconciliation of net income to EBITDA and Adjusted EBITDA is also provided herein.

Overview

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 TiO2 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 TiO2 at our nine TiO2 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 TiO2 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.

Business Environment

The following discussion includes trends and factors that may affect future operating results:

First quarter revenue increased 9% compared to the prior year, driven by higher sales volumes of TiO2 and zircon. For the first quarter of 2024 as compared to the first quarter of 2023, TiO2 volumes increased 18% whereas TiO2 average selling prices declined 10% including product mix impact. Zircon volumes increased 43% partially offset by a decline of 21% in average selling prices. Revenue from other products increased 7% from the first quarter of 2023 to the first quarter of 2024 primarily due to increased volumes across various products. Gross profit decreased for the first quarter of 2024 as compared to the first quarter of 2023 due to the unfavorable impact of selling prices, including product mix partially offset by favorable impacts of sales volumes, improved absorption from higher production volumes and foreign currency.

Sequentially, revenue increased 13% in the first quarter of 2024 compared to the fourth quarter of 2023 primarily due to higher sales volumes of TiO2 and Zircon. TiO2 volumes increased 18% partially offset by a decrease of 1% in average selling prices, including product mix. Revenue from Zircon increased 54% sequentially driven by an increase of 54% in sales volumes while pricing remained flat to the prior quarter. Other product revenues decreased 26% from the fourth quarter of 2023 to the first quarter of 2024 mainly due to the opportunistic sales of ilmenite and a portion of a rare earths tailings deposit in South Africa that occurred in the fourth quarter of 2023, but did not repeat in the first quarter of 2024. Gross profit

30

increased from the fourth quarter of 2023 to the first quarter of 2024 primarily due to higher sales volumes partially offset by lower average selling prices of TiO2, Zircon and pig iron. Gross profit was also favorably impacted by improved absorption from higher production volumes and the absence of non-repeating charges in the fourth quarter of 2023.

As of March 31, 2024, our total available liquidity was $629 million, including $152 million in cash and cash equivalents and $477 million available under revolving credit agreements. As of March 31, 2024, our total debt was $2.8 billion and net debt to trailing-twelve month Adjusted EBITDA was 5.2x with approximately 64% of our interest rates fixed through 2028. The Company has no financial covenants on its term loan or bonds and only one springing financial covenant on its Cash Flow Revolver, which we do not expect to be triggered based on our current scenario planning. Refer to Note 11 of notes to condensed consolidated financial statements for further details.

_______________

(1)EBITDA and Adjusted EBITDA are Non-U.S. GAAP financial measures. Please refer to the “Non-U.S. GAAP Financial Measures” section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations for a discussion of these measures and a reconciliation of these measures to Net (loss) income.

Net sales of $774 million for the three months ended March 31, 2024 increased by 9%, compared to $708 million for the same period in 2023. The increase is primarily due to higher sales volumes of TiO2 and Zircon.

31

Net sales by type of product for the three months ended March 31, 2024 and 2023 were as follows:

	Three Months Ended March 31,
	2024		2023		Variance		Percentage
TiO2	$	605	$	560	$	45	8	%
Zircon	88		72		16		22	%
Other products	81		76		5		7	%
Total net sales	$	774	$	708	$	66	9	%

For the three months ended March 31, 2024, TiO2 revenue was higher by 8% or $45 million compared to the prior year quarter primarily due to an increase of $102 million in sales volumes partially offset by a decrease of $59 million in average selling prices, including product mix. Foreign currency positively impacted TiO2 revenue by $2 million primarily due to the strengthening of the Euro. Zircon revenue increased $16 million primarily due to a 43% increase in sales volumes partially offset by a 21% decrease in average selling prices. Other products revenues increased $5 million from the year-ago quarter primarily due to increased volumes across various products.

Gross profit of $120 million was 15.5% of net sales compared to 18.8% of net sales in the year-ago quarter. The decrease in gross margin is primarily due to:

•the unfavorable impact of 9 points primarily due to a decrease in TiO2 and Zircon selling prices, including product mix, partially offset by

•the favorable impact of 2 points due to changes in foreign exchange rates, primarily as a result of the South African Rand and Australian dollar,

•the favorable impact of 2 points due to zircon volume growth substantially exceeding TiO2 volume growth during the comparable period, and

•the favorable impact of 1 point due to improved absorption from higher production volumes.

Selling, general and administrative expenses increased by $8 million or 11% during the three months ended March 31, 2024 compared to the same period of the prior year primarily driven by a $6 million increase in employee costs. The remaining net increase was driven by individually immaterial amounts.

Income from operations for the three months ended March 31, 2024 was $41 million compared to $62 million in the prior year period. The decrease of $21 million was primarily due to the lower selling prices of TiO2 and Zircon as well as higher SG&A expenses as discussed above.

Adjusted EBITDA as a percentage of net sales was 16.9% for the three months ended March 31, 2024 as compared to 20.6% from the prior year primarily due to the lower gross margin as a result of lower selling prices as discussed above.

Interest expense for the three months ended March 31, 2024 increased by $9 million compared to the same period of 2023 primarily due to the increase in the effective interest rates on our long-term debt facilities and higher average outstanding debt balances period over period.

Other (expense) income, net for the three months ended March 31, 2024 primarily consisted of approximately $3 million of fees associated with the utilization of the Securitization Facility partially offset by $2 million of net realized and unrealized foreign currency gains. The remaining amount was driven by other individually immaterial amounts.

We continue to maintain full valuation allowances related to the total net deferred tax assets in Australia and the United Kingdom.  The provisions for income taxes associated with these jurisdictions 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 other specific tax assets.

The effective tax rate was 550% and 26% for the three months ended March 31, 2024 and 2023, respectively. The effective tax rates for the three months ended March 31, 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.

32

Other Comprehensive Loss

Other comprehensive loss was $32 million in the three months ended March 31, 2024 as compared to other comprehensive loss of $15 million in the three months ended March 31, 2023. The change is primarily due to the unfavorable foreign currency translation adjustments of $41 million in the three months ended March 31, 2024 as compared to unfavorable foreign currency translation adjustments of $13 million in the prior year period. In addition, we recognized a net gain on derivative instruments of $9 million in the three months ended March 31, 2024 as compared to a net loss on derivative instruments of $3 million in the prior year period.

Liquidity and Capital Resources

The following table presents our liquidity as of March 31, 2024 and December 31, 2023:

	March 31, 2024		December 31, 2023
	(Millions of U.S. dollars)
Cash and cash equivalents	$	152	$	273
Available under the Cash Flow Revolver	335		343
Available under the Standard Credit Facility	53		55
Available under the Emirates Revolver	63		64
Available under the SABB Facility	20		20
Available under the Bank Itau Facility	$	6	$	6
Total	$	629	$	761

Historically, we have funded our operations and met our commitments through cash generated by operations, issuance of unsecured notes, bank financings and borrowings under lines of credit. In the next twelve months, we expect that our operations will provide sufficient cash for our operating expenses, capital expenditures, interest payments and debt repayments, however, if necessary, we have the ability to borrow under our short-term credit facilities (see Note 11 of notes to consolidated financial statements). This is predicated on our achieving our forecast which could be negatively impacted by items outside of our control, including, among other things, macroeconomic conditions, inflationary pressures, political instability including the ongoing Russia and Ukraine and Middle East conflicts and any expansion of such conflicts, and supply chain disruptions. If negative events occur in the future, we may need to reduce our capital spend, cut back on operating costs and other items within our control to maintain adequate liquidity.

Working capital (calculated as current assets less current liabilities) was $1.5 billion at March 31, 2024 and $1.4 billion at December 31, 2023.

As of March 31, 2024, the non-guarantor subsidiaries of our Senior Notes due 2029 represented approximately 17% of our total consolidated liabilities and approximately 40% of our total consolidated assets. For the three months ended March 31, 2024, the non-guarantor subsidiaries of our Senior Notes due 2029 represented approximately 45% of our total consolidated net sales. For the three months ended March 31, 2024, the non-guarantor subsidiaries of our Senior Notes due 2029 represented approximately 44% of our consolidated EBITDA (as such term is defined in the 2029 Indenture). In addition, as of March 31, 2024, our non-guarantor subsidiaries had $699 million of total consolidated liabilities (including trade payables but excluding intercompany liabilities), all of which would have been structurally senior to the 2029 Notes. See Note 11 of notes to unaudited condensed consolidated financial statements.

At March 31, 2024, we had outstanding letters of credit and bank guarantees of $102 million. See Note 15 of notes to unaudited condensed consolidated financial statements.

Principal factors that could affect our ability to obtain cash from external sources include (i) debt covenants that limit our total borrowing capacity; (ii) increasing interest rates applicable to our floating rate debt; (iii) increasing demands from third parties for financial assurance or credit enhancement; (iv) credit rating downgrades, which could limit our access to additional debt; (v) a decrease in the market price of our common stock and debt obligations; and (vi) volatility in public debt and equity markets.

33

During the three months ended March 31, 2024, our credit rating with Moody’s remained unchanged at Ba3 stable outlook. Our Standard & Poor's rating and outlook remained the same at B positive and stable, respectively. See Note 11 of notes to unaudited condensed consolidated financial statements.

Cash and Cash Equivalents

We consider all investments with original maturities of three months or less to be cash equivalents. As of March 31, 2024, our cash and cash equivalents were invested in money market funds and we also receive earnings credits for some balances left in our bank operating accounts. We maintain cash and cash equivalents in bank deposit and money market accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are highly rated and geographically dispersed, and we have a policy to limit the amount of credit exposure with any one institution. We have not experienced any losses in such accounts and believe we are not exposed to significant credit risk.

The use of our cash includes payment of our operating expenses, capital expenditures, servicing our interest and debt repayment obligations, cash taxes, making pension contributions and making quarterly dividend payments. Going forward, we expect to continue to invest in our businesses through cost reduction, as well as growth and vertical integration-related capital expenditures including projects such as newTRON and various mine development projects, continued reductions in our debt, continued dividends and share repurchases.

Repatriation of Cash

At March 31, 2024, we held $152 million in cash and cash equivalents in these respective jurisdictions: $19 million in Europe, $35 million in the United States, $32 million in Australia, $22 million in Brazil, $18 million in South Africa, $10 million in Saudi Arabia, $15 million in China and $1 million in India. Our credit facilities limit transfers of funds from subsidiaries in the United States to certain foreign subsidiaries.

At March 31, 2024, Tronox Holdings plc had foreign subsidiaries with undistributed earnings. Although we would not be subject to income tax on these earnings, we have asserted that amounts in specific jurisdictions are indefinitely reinvested outside of the parent's taxing jurisdictions. These amounts could be subject to withholding tax if distributed, but the Company has made no provision for tax related to these undistributed earnings. In 2022, the Company removed its assertion that earnings in China are indefinitely reinvested, and since then, the withholding tax accruals for potential repatriations from that jurisdiction are reflected in the effective tax rate.

Stock Repurchases

On February 21, 2024, in connection with the expiration in February 2024 of the Company's previous share repurchase program, the Company's Board of Directors authorized the repurchase of up to $300 million of the Company's stock through February 21, 2027. During the three months ended March 31, 2024, we made no repurchases of the Company's stock.

Debt Obligations

At March 31, 2024 and December 31, 2023, our long-term debt, net of unamortized discount and debt issuance costs was $2.8 billion and $2.8 billion, respectively. At March 31, 2024 and December 31, 2023, our net debt (the excess of our debt over cash and cash equivalents) was $2.7 billion and $2.6 billion, respectively. See Note 11 of notes to unaudited condensed consolidated financial statements.

On May 1, 2024, Tronox Finance LLC (the “Borrower”), Tronox Holdings plc (the “Company”), certain of the Company’s subsidiaries, the incremental term lender party thereto and HSBC Bank USA, National Association, as Administrative Agent and Collateral Agent, entered into Amendment No. 4 to the Amended and Restated First Lien Credit Agreement (the "2024 Amendment"). The 2024 Amendment provides the Borrower with a new five -year incremental term loan facility ("the 2024 Term Loan Facility") under its credit agreement in an aggregate initial principal amount of $741 million. The proceeds of the 2024 Term Loan Facility were used to repay in full the Company's outstanding 2022 Term Loan and 2023 Term Loan.

Off-Balance Sheet Arrangements

34

On March 15, 2022, the Company entered into an accounts receivable securitization program (“Securitization Facility”) with a financial institution, through our wholly owned special purpose bankruptcy-remote subsidiary, Tronox Securitization LLC (“SPE”). The Securitization Facility permitted the SPE to sell accounts receivable up to $75 million.

In November 2022, the Company amended the receivable purchase agreement to expand the program to include receivables generated by its wholly-owned Australian operating subsidiaries, Tronox Pigment Pty Ltd., Tronox Pigment Bunbury Ltd. and Tronox Mining Australia Ltd. which increased the facility limit to $200 million and to extend the program term to November 2025.

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 result of the Second Amendment, and remain 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. The Fourth Amendment did not impact the three months ended March 31, 2024.

See “Note 5 – Accounts Receivable Securitization Program” in notes to unaudited condensed consolidated financial statements for further details regarding this off-balance sheet program.

Cash Flows

The following table presents cash flow for the periods indicated:

	Three Months Ended March 31,
	2024		2023
	(Millions of U.S. dollars)
Cash used in operating activities	$	(29)	$	(79)
Cash used in investing activities	(76)		(91)
Cash (used in) provided by financing activities	(12)		120
Effects of exchange rate changes on cash and cash equivalents and restricted cash	(2)		1
Net decrease in cash and cash equivalents and restricted cash	$	(119)	$	(49)

Cash Flows used in Operating Activities — Cash used in operating activities of $29 million is primarily driven by $98 million of net loss adjusted for non-cash items offset by a net cash outflow of $127 million related to changes in assets and liabilities. The following table provides our net cash used in operating activities for the three months ended March 31, 2024 and 2023:

	Three Months Ended March 31,
	2024		2023
	(Millions of U.S. dollars)
Net (loss) income	$	(9)	$	25
Adjustments for non-cash items	107		94
Income related cash generation	98		119
Net change in assets and liabilities	(127)		(198)
Cash used in operating activities	$	(29)	$	(79)

Net cash used in operating activities decreased by $50 million year-over-year from $79 million in the prior year to $29 million during the current year. This decrease was generated primarily due to higher use of cash for working capital in the current year primarily driven by an increase in accounts receivable of $94 million and a decrease in accounts payable and accrued liabilities of $49 million. These were partially offset by decreases in inventories and prepaid and other assets of $11 million and $16 million, respectively.

35

Cash Flows used in Investing Activities — Net cash used in investing activities for the three months ended March 31, 2024 was $76 million as compared to $91 million for the same period in 2023 primarily due to lower capital expenditures of $76 million during the current year as compared to $93 million in the prior year as the development of the Atlas Campaspe mine was completed during 2023.

Cash Flows (used in) provided by Financing Activities —Net cash used in financing activities during the three months ended March 31, 2024 was $12 million as compared to cash provided by financing activities of $120 million for the three months ended March 31, 2023. The three months ended March 31, 2024 was primarily comprised of total repayments of $11 million of long-term debt and short-term debt. The three months ended March 31, 2023 was primarily comprised of total draw downs offset by repayments of $126 million on several of our short-term debt facilities.

Contractual Obligations

The following table sets forth information relating to our contractual obligations as of March 31, 2024:

	Contractual Obligation Payments Due by Year (3)(4)
	Total		Less than 1 year	1-3 years	3-5 years	More than 5 years

Non-U.S. GAAP Financial Measures

EBITDA, Adjusted EBITDA, Adjusted net (loss) income attributable to Tronox, Diluted adjusted net income per share attributable to Tronox and net debt to trailing twelve months Adjusted EBITDA, which are used by management to measure performance, are not presented in accordance with U.S. GAAP. We define EBITDA as net (loss) income excluding the impact of income taxes, interest expense, interest income and depreciation, depletion and amortization. We define Adjusted EBITDA as EBITDA excluding the impact of nonrecurring items such as restructuring charges, gain or loss on debt extinguishments, impairment charges, gains or losses on sale of assets, acquisition-related transaction costs and pension settlements and curtailment gains or losses. Adjusted EBITDA also excludes non-cash items such as share-based compensation costs, pension and postretirement costs, and realized and unrealized foreign currency remeasurement gains and losses. We define Adjusted net (loss) income attributable to Tronox as net (loss) income attributable to Tronox excluding the impact of nonrecurring items which are the Company believes are not indicative of its core operating results such as restructuring charges, gain or loss on debt extinguishments, impairment charges, gains or losses on sale of assets, acquisition-

related transaction costs and pension settlements and curtailment gains or losses. We define Diluted adjusted net income per share attributable to Tronox as Diluted net (loss) income per share excluding the impact of nonrecurring items which are the Company believes are not indicative of its core operating results such as restructuring charges, gain or loss on debt extinguishments, impairment charges, gains or losses on sale of assets, acquisition-related transaction costs and pension settlements and curtailment gains or losses.

Management believes that EBITDA, Adjusted EBITDA, Adjusted net (loss) income attributable to Tronox, Diluted adjusted net (loss) income per share attributable to Tronox and net debt to trailing twelve months Adjusted EBITDA are useful to investors, as it is commonly used in the industry as a means of evaluating operating performance. We do not intend for these non-U.S. GAAP financial measures to be a substitute for any U.S. GAAP financial information. Readers of these statements should use these non-U.S. GAAP financial measures only in conjunction with the comparable U.S. GAAP financial measures. Since other companies may calculate EBITDA, Adjusted EBITDA, Adjusted net (loss) income attributable to Tronox, Diluted adjusted net (loss) income per share attributable to Tronox and net debt to trailing twelve months Adjusted EBITDA differently than we do, EBITDA, Adjusted EBITDA, Adjusted net (loss) income attributable to Tronox, Diluted adjusted net income per share attributable to Tronox and net debt to trailing twelve months Adjusted EBITDA, as presented herein, may not be comparable to similarly titled measures reported by other companies. Management believes these non-U.S. GAAP financial measures:

•reflect our ongoing business in a manner that allows for meaningful period-to-period comparison and analysis of trends in our business, as they exclude income and expense that are not reflective of ongoing operating results;

•provide useful information in understanding and evaluating our operating results and comparing financial results across periods; and

•provide a normalized view of our operating performance by excluding items that are either noncash or infrequently occurring.

These non-U.S. GAAP measures are the primary measures management uses for planning and budgeting processes, and to monitor and evaluate financial and operating results. In addition, Adjusted EBITDA is a factor in evaluating management’s performance when determining incentive compensation.

Recent Accounting Pronouncements

See Note 1 of notes to unaudited condensed consolidated financial statements for recently issued accounting pronouncements.

Environmental Matters

We are subject to a broad array of international, federal, state, and local laws and regulations relating to safety, pollution, protection of the environment, and the generation, storage, handling, transportation, treatment, disposal, and remediation of hazardous substances and waste materials. In the ordinary course of business, we are subject to frequent environmental inspections and monitoring, and occasional investigations by governmental enforcement authorities. Under these laws, we are or may be required to obtain or maintain permits or licenses in connection with our operations. In addition, under these laws, we are or may be required to remove or mitigate the effects on the environment of the disposal or release of chemical, petroleum, low-level radioactive and other substances at our facilities. We may incur future costs for capital improvements and general compliance under environmental, health, and safety laws, including costs to acquire, maintain, and repair pollution control equipment. Environmental laws and regulations are becoming increasingly stringent, and compliance costs are significant and will continue to be significant in the foreseeable future. There can be no assurance that such laws and regulations or any environmental law or regulation enacted in the future is not likely to have a material effect on our business. We believe we are in compliance with applicable environmental rules and regulations in all material respects.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market, credit, operational, and liquidity risks in the normal course of business, which are discussed below. We manage these risks through normal operating and financing activities and, when appropriate, with derivative instruments. We do not invest in derivative instruments for speculative purposes, but historically have entered into, and may enter into, derivative instruments for hedging purposes in order to reduce the exposure to fluctuations in interest rates, natural gas prices and exchange rates.

Market Risk

A substantial portion of our products and raw materials are commodities that reprice as market supply and demand fundamentals change. Accordingly, product margins and the level of our profitability tend to vary with changes in the business cycle. Our TiO2 prices may do so in the near term as ore prices and pigment prices are expected to fluctuate over the next few years. We try to protect against such instability through various business strategies. These include provisions in sales contracts allowing us to pass on higher raw material costs through timely price increases and formula price contracts to transfer or share commodity price risk, enter into fixed purchase commitments to eliminate volatility in commodity purchases, as well as using varying contract term lengths and selling to a diverse mix of customers by geography and industry to reap the benefits of a diverse portfolio.

Credit Risk

Credit risk is the risk that a borrower or a counterparty will fail to meet their obligations. A significant portion of our liquidity is concentrated in trade accounts receivable that arise from sales of our products to customers. In the case of TiO2, the high level of industry concentration has the potential to impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic, industry or other conditions. We have significant exposure to credit risk in industries that are affected by cyclical economic fluctuations. We perform ongoing credit evaluations of our customers from time to time, as deemed appropriate, to mitigate credit risk but generally do not require collateral. Our contracts typically enable us to tighten credit terms if we perceive additional credit risk; however, historic losses due to write offs of bad debt have been insignificant. In addition, due to our international operations, we are subject to potential trade restrictions and sovereign risk in certain countries in which we operate. We maintain allowances for potential credit losses based on specific customer review and current financial conditions. During both the three months ended March 31, 2024 and 2023, our ten largest third-party customers represented 37% of our consolidated net sales. During the three months ended March 31, 2024 and 2023, no single customer accounted for 10% of our consolidated net sales.

Interest Rate Risk

Interest rate risk arises from the possibility that changes in interest rates will impact our financial results. We are exposed to interest rate risk on our floating rate debt, the Term Loan Facility, the 2022 Term Loan Facility, the 2023 Term Loan Facility, Standard Bank Term Loan Facility, and Cash Flow Revolver, Standard Bank Revolver, Emirates Revolver and SABB Credit Facility balances. Using a sensitivity analysis as of March 31, 2024, a hypothetical 1% increase in interest rates would result in a net decrease to pre-tax income of approximately $7 million on an annualized basis. This is due to the fact that earnings on our floating rate financial assets of $47 million at March 31, 2024 would increase by the full 1%, offsetting the impact of a 1% increase in interest expense on our floating rate debt of approximately $776 million.

41

As of March 31, 2024, the Company maintains a total of $950 million of interest rate swaps 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. The Company's objectives in using the interest rate swap agreements are to add stability to interest expense and to manage its exposure to interest rate movements. Refer to Note 12 of notes to unaudited condensed consolidated financial statements for further details.

Currency Risk

Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact our balance sheets due to the translation of our assets and liabilities denominated in foreign currencies, as well as our earnings due to the translation of certain of our subsidiaries’ statements of income from local currencies to U.S. dollars, as well as due to remeasurement of assets and liabilities denominated in currencies other than a subsidiary’s functional currency. We manufacture and market our products in a number of countries throughout the world and, as a result, are exposed to changes in foreign currency exchange rates, particularly in Australia, Brazil, China, South Africa, the Netherlands and the United Kingdom. The exposure is most prevalent in South Africa and Australia as the majority of revenues are earned in U.S. dollars while expenses are primarily incurred in local currencies. Since we are exposed to movements in the South African Rand, the Australian Dollar, the Euro and the Pound Sterling versus the U.S. dollar, we may enter into forward contracts to buy and sell foreign currencies as “economic hedges” for these foreign currency transactions.

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 March 31, 2024, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates or to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. 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, of which $2 million was recognized in earnings during the three months ended March 31, 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, 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 March 31, 2024, there was (i) 971 million South African Rand (or approximately $51 million at March 31, 2024 exchange rate), (ii) 138 million Australian dollars (or approximately $90 million at the March 31, 2024 exchange rate), (iii) 48 million Pound Sterling (or approximately $61 million at the March 31, 2024 exchange rate), (iv) 7 million Euro (or approximately $8 million at the March 31, 2024 exchange rate), and (v) 88 million Saudi Riyal (or approximately $23 million at the March 31, 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 $44 million at the March 31, 2024 exchange rate), (ii) 153 million Australian dollars (or approximately $100 million at the March 31, 2024 exchange rate), (iii) 45 million Pound Sterling (or approximately $57 million at the March 31, 2024 exchange rate), (iv) 45 million Euro (or approximately $49 million at the March 31, 2024 exchange rate) and (v) 67 million Saudi Riyal (or approximately $18 million at the March 31, 2024 exchange rate) of notional amounts of outstanding foreign currency contracts.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision of and with the participation of Tronox’s management, including our CEO and CFO, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) (the “Exchange Act”), as of March 31, 2024, the end of the period covered by this report. Based on that evaluation, we have concluded that the Company’s disclosure controls and procedures were effective as of that date. Tronox’s disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by Tronox in the reports that it files or submits under the Exchange Act is accumulated and communicated to Tronox’s management, including Tronox’s principal executive and principal financial officers, or other persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.  Based on that evaluation, we have concluded that the Company’s disclosure controls and procedures were effective as of that date. 

An evaluation of our internal control over financial reporting was also performed to determine whether any changes have occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Changes in Internal Control over Financial Reporting

We are currently undergoing a multi-year IT-enabled transformation program that includes increased automation of both operational and financial systems, including the global enterprise risk management program, through new and upgraded systems, technology and processes. As part of such transformation program, during the third quarter of 2022, we implemented upgrades to our financial systems and platforms in certain regions. The full implementation is expected to occur in phases over a number of years. As the phased implementation of this system occurs, we expect certain changes to our processes and procedures which, in turn, will result in changes to our internal control over financial reporting.

While we expect this transformation program to strengthen our internal financial controls, management will continue to evaluate and monitor our internal controls as processes and procedures in each of the affected areas evolve.

Other than as discussed above, during the quarter ended March 31, 2024, there were no other changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.    Legal Proceedings

Information required by this item is incorporated herein by reference to the section captioned “Notes to Consolidated Financial Statements, Note 15 - Commitments and Contingencies” of this Form 10-Q.

SEC regulations require us to disclose certain information about administrative or judicial proceedings to which a governmental authority is party arising under federal, state or local environmental provisions if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to the SEC regulations, the Company uses a threshold of $1 million or more for purposes of determining whether disclosure of any such proceedings is required.

Item 1A.    Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed under “Risk Factors” included in our Annual Report on Form 10-K and any subsequent filings thereto with the SEC. The risks described herein or in the Form 10-K and any subsequent filings thereto with the SEC are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. There have been no material changes from the risk factors disclosed under the heading “Risk Factors” in our Form 10-K.

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 TiO2 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 TiO2 at our nine TiO2 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 TiO2 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 March 31, 2024, and its results of operations for the three months ended March 31, 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

3 Months Ended

Mar. 31, 2024

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 March 31, 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 March 31, 2024 and December 31, 2023 were $1 million and less than $1 million, respectively. 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 March 31,
	2024		2023
North America	$	192	$	189
South and Central America	46		42
Europe, Middle-East and Africa	309		282
Asia Pacific	227		195
Total net sales	$	774	$	708

Net sales from external customers for each similar type of product were as follows:

	Three Months Ended March 31,
	2024		2023
TiO2	$	605	$	560
Zircon	88		72
Other products	81		76
Total net sales	$	774	$	708

Other products mainly include pig iron, TiCl4 and other mining products.

During both the three months ended March 31, 2024 and 2023, our ten largest third-party customers represented 37% of our consolidated net sales. During the three months ended March 31, 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 March 31,
	2024			2023
Income tax provision	$	(11)		$	(9)
Income before income taxes	$	2		$	34
Effective tax rate	550		%	26		%

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 March 31, 2024 and 2023 was 25% and 19%, respectively. 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 months ended March 31, 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.

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 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.

Accounts Receivable Securitization Program

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. The Fourth Amendment had no impact to financial position or financial results at and for the three months ended March 31, 2024.

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 March 31, 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 $200 million and $186 million, respectively. Additionally, at March 31, 2024 and December 31, 2023, we retained approximately $171 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 March 31,

Cash proceeds from collections reinvested in the program	$	222	$	144
Incremental accounts receivables sold	236		138

Interest Rate Risk

As of March 31, 2024, the Company maintains a total of $950 million of interest rate swaps 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 March 31, 2024 and December 31, 2023, the net unrealized gain of $28 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 months ended March 31, 2024, the amounts recorded in interest expense related to the interest-rate swap agreements were $8 million, of which $2 million for each period was reclassified from "Accumulated other comprehensive loss" to interest expense. For the three months ended March 31, 2023, the net amounts recorded in interest expense related to the interest-rate swap agreements were $4 million.

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 March 31, 2024, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates or to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. 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, of which $2 million was recognized in earnings during the three months ended March 31, 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 March 31, 2024, there was (i) 971 million South African Rand (or approximately $51 million at March 31, 2024 exchange rate), (ii) 138 million Australian dollars (or approximately $90 million at the March 31, 2024 exchange rate), (iii) 48 million Pound Sterling (or approximately $61 million at the March 31, 2024 exchange rate), (iv) 7 million Euro (or approximately $8 million at the March 31, 2024 exchange rate), and (v) 88 million Saudi Riyal (or approximately $23 million at the March 31, 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 $44 million at the March 31, 2024 exchange rate), (ii) 153 million Australian dollars (or approximately $100 million at the March 31, 2024 exchange rate), (iii) 45 million Pound Sterling (or approximately $57 million at the March 31, 2024 exchange rate), (iv) 45 million Euro (or approximately $49 million at the March 31, 2024 exchange rate) and (v) 67 million Saudi Riyal (or approximately $18 million at the March 31, 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 March 31, 2024 and December 31, 2023:

	March 31, 2024		December 31, 2023
	Asset	Liability	Asset	Liability
Term Loan Facility	—	903	—	903
2022 Term Loan Facility	—	393	—	394
2023 Term Loan Facility	—	350	—	351
Standard Bank Term Loan Facility	—	60	—	64
Senior Notes due 2029	—	966	—	956
Australian Government Loan	—	1	—	1
MGT Loan	—	23	—	25
Interest rate swaps	28	—	18	—
Natural gas hedges	—	1	—	1
Foreign currency contracts	1	—	1	1

We determined the fair value of the Term Loan Facility, the 2022 Term Loan Facility, the 2023 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 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 March 31, 2024, purchase commitments were $280 million for the remainder of 2024, $170 million for 2025, $161 million for 2026, $157 million for 2027, $286 million for 2028, and $1,431 million thereafter.

Letters of Credit—At March 31, 2024, we had outstanding letters of credit and bank guarantees of $102 million, of which $63 million were letters of credit, of which $48 million is related to the sale of Hawkins Point as discussed below, and $39 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 TiO2 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 March 31, 2024, we have a provision of $42 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. In February 2024, we received a summons from the UK Health and Safety Executive alleging non-compliance with UK health and safety legislation at the Stallingborough pigment plant resulting from an incident involving an employee in August 2022. Based on our current understanding, we do not believe the enforcement action with regards to this incident will have a material adverse effect on our business, financial condition and results of operations.

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

Restricted Share Units (“RSUs”)

2024 Grant - During the three months ended March 31, 2024, the Company granted both time-based and performance-based awards to certain members of management. A total of 806,893 of time-based awards were granted to management which will vest ratably over a three-year period ending March 5, 2027. A total of 806,900 of performance-based awards were granted, of which 403,450 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 403,450 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 $21.68. 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 March 31, 2024 was $46 million, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of approximately 2.3 years.

During both the three months ended March 31, 2024 and 2023, we recorded $6 million of stock compensation expense.

Tasnee / Cristal

At March 31, 2024, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a subsidiary of Tasnee, continues to own 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 March 31, 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:

Amount due to AMIC for slag purchases	8	—

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." 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.

On December 29, 2019, we entered into an agreement with Cristal to acquire certain assets co-located at our Yanbu facility which produces metal grade TiCl4 ("MGT"). 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 TiCl4, 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. Repayment of the $36 million note payable is based on a fixed U.S. dollar amount per metric ton quantity of MGT delivered by us to ATTM over time and therefore the ultimate maturity date is variable in nature. If ATTM fails to purchase MGT from us under certain contractually agreed upon conditions, then at our election we may terminate the MGT supply agreement with ATTM and we will no longer owe any amount under the loan agreement with Cristal. We currently estimate the ultimate maturity to be between approximately four and five years, subject to actual future MGT production levels. The interest rate on the note payable is based on the SAIBOR plus a premium. The note payable is recorded within "Long-term debt, net" and "Long-term debt due within one year" on the unaudited Condensed Consolidated Balance Sheet.

	March 31, 2024	December 31, 2023
Note payable, due within 1 year	7	7

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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 March 31, 2024, and its results of operations for the three months ended March 31, 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

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.

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
