Exhibit 99.1

Tronox Reports Second Quarter 2025 Financial Results

STAMFORD, Conn., July 30, 2025/PRNewswire/ — Tronox Holdings plc (NYSE:TROX) (“Tronox” or the “Company”), the world’s leading integrated manufacturer of titanium dioxide ("TiO₂") pigment, today reported its financial results for the quarter ending June 30, 2025, as follows:

Second Quarter 2025 Financial Highlights:

● Revenue of $731 million, a 1% decrease compared to the prior quarter and an 11% decrease compared to the prior year

● Loss from operations of $35 million; Net loss of $85 million including $39 million of restructuring and other charges, net of taxes, primarily costs associated with the idling of the Company's Botlek pigment plant as announced in March; adjusted net loss was $45 million (non-GAAP)

● GAAP diluted loss per share was $0.53; Adjusted diluted loss per share was $0.28 (non-GAAP)

● Adjusted EBITDA of $93 million; Adjusted EBITDA margin of 12.7% (non-GAAP)

● Capital expenditures of $83 million in the quarter

Updated Outlook:

● Expect 2025 Revenue of $3.0-$3.1 billion, Adjusted EBITDA of $410-$460 million, and free cash flow to be a use of $100-$170 million

● In response to the extended market downturn, the Company is adjusting its capital allocation priorities by further reducing capital expenditures (now expected to be less than $330 million) and reducing the dividend by 60% to provide near-term balance sheet flexibility

This outlook is based on Tronox's views on current global economic activity and is subject to changes and impacts associated with the macroeconomic conditions, global supply chain, and inflation-related challenges, among others.

------

Note: For the Company's guidance with respect to 2025 Adjusted EBITDA and free cash flow, 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.

CEO's Remarks

Chief Executive Officer John D. Romano commented, “Tronox’s second quarter results were impacted by weaker demand across most of our end markets. This resulted in a softer than anticipated coatings season and heightened competitive dynamics. TiO₂ volumes in the second quarter were lower by 2% sequentially and 11% year-over-year, reflecting weaker than usual seasonality across all regions. Broader macroeconomic pressures, including elevated interest rates and tariff-related uncertainties, continued to weigh on consumer discretionary spending, while home sales and construction activity remained subdued. Additionally, delays in Brazil's anti-dumping investigation impacted our sales in the region, though we are encouraged by early momentum in India following the implementation of duties in May. Operational costs remained in-line with expectations and our mining projects continue to progress on schedule.

“In response to the prolonged weakness in the market, we are executing on our disciplined strategy to manage through the downturn and optimize earnings and cash. Our cost improvement program is progressing ahead of plan and proving essential in mitigating increasing raw material and operational cost pressures. We remain confident in our ability to deliver $125–$175 million in sustainable, run-rate savings by the end of 2026. We are also selectively adjusting operating rates to preserve cash and deploying targeted commercial initiatives to ensure we maintain and grow our market share in key markets.

“Additionally, we revised our 2025 financial outlook and are taking proactive steps, including adjusting our capital allocation priorities to maximize long-term shareholder value creation. We further reduced capital expenditures this year while ensuring we are not compromising critical investments that support safe and reliable operations. Our Board of Directors declared a dividend of $0.05 per share for the third quarter, a reduction of 60% that will provide enhanced balance sheet flexibility. We will reevaluate as the market recovers to ensure we target a competitive dividend yield.”

Mr. Romano concluded, “Tronox is well positioned to navigate through this continued economic uncertainty. We firmly believe the actions we are taking will further strengthen our business to ensure ample liquidity and solidify our position as the preferred strategic, global supplier for our customers. I remain confident in Tronox’s long-term trajectory and our commitment to delivering sustained value for shareholders.”

Dividend Declaration

The Company’s Board of Directors declared a quarterly cash dividend of $0.05 per share payable on October 3, 2025 to shareholders of record at the close of business on August 11, 2025.

Second Quarter 2025 Results

(Comparisons are to prior year (Q2 2025 vs. Q2 2024) unless otherwise noted)

The Company recorded second quarter revenue of $731 million, a decrease of 11% primarily driven by lower TiO₂ and zircon sales volumes and lower average selling prices of zircon.

Revenue from TiO₂ sales was $587 million, a decline of 10% driven by an 11% decline in volumes slightly offset by a 1% favorable impact due to exchange rates, while average selling prices including mix was flat. Sequentially, TiO₂ sales increased 1%, driven by a 1% increase in average selling prices including mix and a favorable 2% exchange rate impact, partially offset by a 2% decrease in sales volumes.

Zircon revenue decreased 20% to $68 million, driven by a 10% decline in sales volumes and a 10% decrease in average selling prices including mix. Sequentially, zircon revenue decreased 1%, driven by a 2% decrease in average selling prices including mix partially offset by a 1% increase in sales volumes.

Revenue from other products was $76 million, a decline of 7% year-over-year primarily due to lower sales volumes of pig iron. Sequentially, revenue from other products decreased 11%.

Net loss attributable to Tronox in the quarter was $84 million, or a loss of $0.53 per diluted share, compared to net income attributable to Tronox of $16 million, or income of $0.10 per diluted share in the year-ago period. Non-recurring adjustments totaled $39 million, or $0.25 per diluted share. Excluding these items, adjusted net loss attributable to Tronox (non-GAAP) was $45 million, or a loss of $0.28 per diluted share.

Adjusted EBITDA of $93 million represented a 42% decrease, driven by lower sales volumes, higher production costs, lower average selling prices including mix and higher freight costs, partially offset by favorable exchange rate movements and lower corporate costs. Adjusted EBITDA margin was 12.7%.

Sequentially, Adjusted EBITDA decreased 17% due to higher production costs, non-repeating insurance proceeds received in the first quarter related to the 2023 Botlek supplier outage, lower sales volumes and higher freight costs, partially offset by favorable average selling prices including mix, tailwinds from exchange rate movements and lower corporate costs.

The Company's selling, general and administrative expenses were $72 million for the quarter, a decrease of 3%. Tronox's net interest expense in the quarter was $44 million. Depreciation, depletion and amortization expense was $74 million.

Balance Sheet, Cash Flow and Capital Allocation

Tronox ended the quarter with $3.1 billion of total debt, $2.9 billion of net debt and a net leverage ratio of 6.1x on a trailing twelve-month basis. Available liquidity at the end of the quarter totaled $397 million, including $132 million in cash and cash equivalents and $265 million available under our revolving credit agreements. The next significant debt maturity for the Company is not until 2029. Tronox does not have any financial covenants on its term loans or bonds.

Free cash flow for the quarter was a use of $55 million. Capital expenditures were $83 million, including investments in the Company's key capital projects to replace existing mines reaching their end of life and sustain the Company's vertical integration benefit.

Outlook

Tronox is adjusting its previous guidance for 2025. Based on current market conditions, the Company is expecting FY 2025 revenue to be $3.0-$3.1 billion and Adjusted EBITDA to be $410-$460 million. These ranges assume lower pigment and zircon volumes and price than previously anticipated, offset by revenue growth from strategic sales of other products and improved production costs in the second half of the year compared to the first half. The Company expects free cash flow to be a use of $100-$170 million as a result of the lower pigment and zircon sales. The Company further reduced capital expenditures to now be less than $330 million for the year. The Company remains on track to deliver $125-$175 million of sustainable, run-rate cost improvements deliverable by the end of 2026.
