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 June 30, 2026, purchase commitments were $188 million for the remainder of 2026, $323 million for 2027, $195 million for 2028, $157 million for 2029, $144 million for 2030, and $2,372 million thereafter. Letters of Credit—At June 30, 2026, we had outstanding letters of credit and bank guarantees of $163 million, of which $70 million were letters of credit (including $43 million is related to the sale of Hawkins Point as discussed below), and $93 million were bank guarantees. Amounts for performance bonds were not material. Environmental Matters—It is our policy to record appropriate liabilities for environmental matters when remedial efforts are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. We expect to fund expenditures for these matters from operating cash flows. The timing of cash expenditures depends principally on the timing of remedial investigations and feasibility studies, regulatory approval of cleanup projects, remedial techniques to be utilized and agreements with other parties. Included in these environmental matters is the following: Hawkins Point Plant. Residual waste mud, known as Batch Attack Mud, and a spent sulfuric waste stream were deposited in an onsite repository (the “Batch Attack Lagoon”) at a former TiO2 manufacturing site, Hawkins Point Plant in Baltimore, Maryland, operated by Cristal USA, Inc. from 1954 until 2011. We assumed responsibility for remediation of the Hawkins Point Plant when we acquired the TiO 2 business of Cristal in April 2019. On December 21, 2022, we sold the Hawkins Point Plant to the Maryland Port Administration ("MPA"), a state agency controlled by the Maryland Department of Transportation. Pursuant to the terms of the transaction, MPA became the lead party in developing and implementing appropriate measures to address, treat, control, and mitigate the environmental conditions at the property under the regulatory oversight of the Maryland Department of the Environment ("MDE"). Under MPA ownership, the Hawkins Point Plant will be utilized for storage and beneficial reuse of dredged material from the Port of Baltimore. In exchange for transferring ownership of the site to MPA, Tronox has agreed to make scheduled, annual payments to MPA which together with scheduled, annual contributions from MPA will be used to remediate the property. The sale of the p roperty to MPA did not have a material impact to the Consolidated Statement of Operations. As of June 30, 2026, we have a provision of $41 million, of which $26 million and $15 million are included in "Environmental liabilities" and "Accrued Liabilities", respectively, 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 is the following: On September 3, 2025, a putative class action was filed in the U.S. District Court for the District of Connecticut against the Company and certain individual defendants. On January 22, 2026, the court appointed a lead plaintiff for the putative class. An amended complaint was filed on April 7, 2026. The amended complaint alleges that defendants violated the U.S. federal securities laws by making false and misleading statements in public filings and other public statements during the period from May 1, 2025 through July 30, 2025 with respect to the Company's financial outlook, demand for its pigment products, and competition in the European market. The case is in its early stages. No specific amount of damages has been alleged. On June 8, 2026, defendants filed a motion to dismiss the amended complaint. The Company and the individual defendants intend to defend themselves vigorously against this lawsuit.
