FIRST QUARTER HIGHLIGHTS *Delivered strong performance due to continued strength in the paperboard business and improvements in tissue *Higher pricing in both businesses helping to offset inflation *Net sales of $488 million, up 15% compared to the first quarter of last year *Net income of $17 million, or $0.97 per diluted share *Reduced net debt by $31 million in the quarter

Chief Executive Officer John D. Romano commented “Tronox delivered fourth quarter results in line with expectations despite continued macro weakness. Strong TiO2 commercial performance in Asia Pacific and Latin America mitigated continued lagging demand in Europe, while North America performed as expected. Zircon sales exceeded our previous guidance, driven by strong execution from our commercial group. Additionally, despite significant competitive dynamics across all products, pricing came in as anticipated. On operations, we realized $75 million of production cost improvements compared to Q4 2023, owing to consistent and reliable performance in the fourth quarter. As a result, Tronox delivered an Adjusted EBITDA of $129 million in the quarter, well within the previously guided range of $120-$135 million, and an Adjusted EBITDA margin of 19.1%. “Reflecting on the full year, I am proud of the work our team did to remain focused on the things we can control and influence. In 2024, we heightened our focus on safety and reduced our total recordable injuries by 23%. We enhanced our focus on operations, resulting in significant production cost improvements in the second half of 2024. We continued to execute on our capital allocation strategy, prioritizing investments in the business including replacing our mines reaching end of life. Additionally, we strengthened our balance sheet through opportunistic refinancing transactions and returned $80 million to shareholders in the form of dividends.”
