Exhibit 99.1

Safe Harbor Statement and Non-U.S. GAAP Financial Terms 2 Cautionary Statement about Forward-Looking Statements Statements in this presentation that are not historical are forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. These forward-looking statements, which are subject to known and unknown risks, uncertainties and assumptions about us, may include projections of our future financial performance, anticipated completion of extensions and upgrades to our mining and operations, anticipated trends in our business and industry, anticipated costs and benefits of project newTRON and Atlas Campaspe, the Company's anticipated capital allocation strategy including future capital expenditures, and our sustainability goals, commitments and programs. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance, actual synergies, or achievements to differ materially from the results, level of activity, performance, anticipated synergies or achievements expressed or implied by the forward-looking statements. Significant risks and uncertainties may relate to, but are not limited to, macroeconomic conditions; inflationary pressures and energy costs; currency movements; political instability, including the ongoing Russia and Ukraine conflict and any expansion of such conflict; supply chain disruptions; market conditions and price volatility for titanium dioxide, zircon and other feedstock materials, as well as global and regional economic downturns, that adversely affect the demand for our end-use products; disruptions in production at our mining and manufacturing facilities; and other financial, economic, competitive, environmental, political, legal and regulatory factors. These and other risk factors are discussed in the Company's filings with the Securities and Exchange Commission. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for our management to predict all risks and uncertainties, nor can management assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, synergies or achievements. Neither we nor any other person assumes responsibility for the accuracy or completeness of any of these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. Unless otherwise required by applicable laws, we undertake no obligation to update or revise any forward-looking statements, whether because of new information or future developments. Use of Non-GAAP Information To provide investors and others with additional information regarding the financial results of Tronox Holdings plc, we have disclosed in this presentation certain non-U.S. GAAP operating performance measures of EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and Adjusted net income attributable to Tronox on a per share basis, and a non-U.S. GAAP liquidity measure of Free Cash Flow. These non-U.S. GAAP financial measures are a supplement to and not a substitute for or superior to, the Company's results presented in accordance with U.S. GAAP. The non-U.S. GAAP financial measures presented by the Company may be different from non-U.S. GAAP financial measures presented by other companies. Specifically, the Company believes the non-U.S. GAAP information provides useful measures to investors regarding the Company's financial performance by excluding certain costs and expenses that the Company believes are not indicative of its core operating results. The presentation of these non-U.S. GAAP financial measures is not meant to be considered in isolation or as a substitute for results or guidance prepared and presented in accordance with U.S. GAAP. A reconciliation of the non-U.S. GAAP financial measures to U.S. GAAP results is included herein. For the Company's guidance with respect to fourth quarter 2022 non-U.S. GAAP financial measures, the Company is not able to provide without unreasonable effort the most directly comparable GAAP financial measure, or reconciliation to such GAAP financial measure, because certain items that impact such measures are uncertain, out of the Company's control or cannot be reasonably predicted. For the Company's guidance with respect to fourth quarter 2022 and full year 2022 non-GAAP measures, we are not able to provide without unreasonable effort the most directly comparable GAAP financial measure, or reconciliation to such GAAP financial measure, because certain items that impact such measures are uncertain, out of the Company's control or cannot be reasonably predicted.
