TABLE OF CONTENTS
SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
We have made statements under the captions “Business,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, and in other sections of this Form 10-K that are forward-looking statements. 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. 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 based on our growth strategies and anticipated trends in our business. 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 or achievements to differ materially from the results, level of activity, performance or achievements expressed or implied by the forward-looking statements. In particular, you should consider the numerous risks and uncertainties outlined in “Risk Factors.”
These risks and uncertainties are not exhaustive. Other sections of this Form 10-K may include additional factors, which could adversely impact our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment.

For the purposes of this discussion, references to “we,” “us,” and, “our” refer to Tronox Holdings plc, together with its consolidated subsidiaries (collectively referred to as “Tronox” or the "Company”). We are a public limited company formed under the laws of England and Wales. We are considered a domestic company in the United Kingdom and, as such, are required to comply with filing requirements in the United Kingdom. Additionally, we are not considered a “foreign private issuer” in the U.S.; therefore, we are required to comply with the reporting and other requirements imposed by the U.S. securities law on U.S. domestic issuers, which, among other things, requires reporting under accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Item 1. Business
Overview
Tronox is the world’s leading vertically integrated manufacturer of TiO 2 pigment. We operate titanium-bearing mineral sand mines and beneficiation and smelting operations in Australia and South Africa to produce feedstock materials that can be processed into TiO 2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and ultrafine TiO 2 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 TiO 2 at our seven pigment facilities located in the United States, Australia, Brazil, UK, France, and the Kingdom of Saudi Arabia. We believe that vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our approximately 1,200 TiO 2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands also creates meaningful quantities of co-products including zircon, pig iron and the rare-earth bearing mineral, monazite, which we also supply to customers around the world.
The following chart highlights the TiO 2 value chain we participate in.

2025 Key Strategic Initiatives
The following sets forth the key strategic initiatives underway in 2025:
Become the Low Cost TiO 2 Producer by Investing in our Business Processes and Strengthening Vertical Integration
Our ability to compete effectively in the TiO 2 industry is determined by many factors, including innovation, reliability, product quality, customer service and price. The business processes that allow us to maximize the benefit of our vertical integration and global footprint --- the so-called “hidden factory” --- needs to be optimized if we are to successfully meet the pricing and other competitive pressures that characterize our industry. Throughout 2025, the Company reinforced its commitment to sustaining and enhancing its vertical integration competitive advantage. Key milestones were the successful commissioning of the Fairbreeze extension and the completion of construction at Namakwa East OFS which is currently in the process of being commissioned - two major mining projects in South Africa which replace existing mines approaching end of life. These new sites are expected to provide abundant reserves of natural rutile and zircon, along with high-grade ilmenite suitable for direct use or slag processing, ensuring a secure and cost-effective feedstock supply for years to come. These strategic investments are projected to deliver returns above the Company's cost of capital.

TABLE OF CONTENTS
Sustainable Cost Improvement Plan
In 2025, we launched a comprehensive Sustainable Cost Improvement Program designed to enhance cost efficiency and optimize asset performance across all aspects of our business. This initiative delivered over $90 million in annualized savings by year-end 2025 and is projected to achieve approximately $125-$175 million in annualized savings (including the $90 million realized in 2025) by the end of 2026. The program focuses on four key pillars: Operational Excellence, Technology Enablement, Supply Chain Optimization, and Selling, General & Administrative Expenses Alignment. We believe this strategic approach will position us to sustain long-term value creation while maintaining operational resilience.
Maintaining Adequate Liquidity
We took proactive measures to bolster liquidity and preserve flexibility, which included the successful execution of a $400 million senior secured bond offering which closed in September 2025, and reducing the quarterly dividend by 60%, effective in the third quarter of 2025. At the same time, throughout 2025, we implemented targeted operational measures to manage near-term cash flow, including: shutting down the Botlek pigment plant in the Netherlands, idling the Fuzhou pigment plant in China, and temporarily idling one furnace at the Namakwa smelter.
Develop Our Position as a Significant Supplier of Rare Earth Oxides
Tronox’s existing mining operations and tailing piles in South Africa and Australia contain significant quantities of monazite, a mineral containing rare earth elements (REEs) widely recognized as a critical mineral for the energy transformation underway to decarbonize the world’s economy. For these applications, REE must first be processed into an oxide form --- rare earth oxides or “REO” --- that can then be metallized for the production of permanent magnets. Every step of the REE supply chain today is dominated by China. China’s dominance of the processing of REO and production of permanent magnets is widely recognized as a serious strategic challenge by democratic governments around the world.
The separation, beneficiation and processing technologies that Tronox uses to turn titanium-bearing ores into TiO 2 are applicable for turning monazite into REO. In the past, we sold our monazite in unconcentrated form as a waste product but given the increased value associated with REE, we are now seeking to maximize the value of our existing geologic resources and deploy our substantial technical know how and human capital to become a significant supplier of REO to non-Chinese producers of metals and permanent magnets.
In 2025, we received coordinated, non-binding and conditional letters of support/interest from Export Finance Australia and Export-Import Bank of the United States, respectively for up to an aggregate of US $600 million in limited or non-recourse financing to support the development of Tronox's rare earth supply chain. In addition, we took an approximate 5% equity interest in Lion Rock Minerals (ASX-LRM) ("LRM"), a mineral exploration company whose Minta and Minta Est deposits have the potential to be a major source of high quality monazite and rutile. Continuing to seek funding sources and develop a rare earth minerals business is an ongoing focus of management. See "Risk Factors - The Company may not be successful in arranging required financing and/or developing a financeable structure for its rare earth initiatives, and even if the required financing is obtained and/or a financing structure is achieved, the Company may not be successful in developing a viable rare earth supply chain."
Our Principal Products
TiO 2
TiO 2 Pigment
TiO 2 pigment is used in a wide range of products due to its ability to impart whiteness, brightness, and opacity. TiO 2 pigment is used extensively in the manufacture of paint and other coatings, plastics and paper, and in a wide range of other applications. Moreover, it is a critical component of everyday consumer applications due to its superior ability to cover or mask other materials effectively and efficiently relative to alternative white pigments and extenders. TiO 2 pigment is considered to be a quality of life product. At present, it is our belief that there is no effective substitute for TiO 2 pigment because no other white pigment has the physical properties for achieving comparable opacity and brightness or can be incorporated as cost effectively.
Ultrafine Specialty TiO 2
We produce ultrafine TiO 2 at our manufacturing facility in Thann, France. We market ultrafine TiO 2 products under the CristalActiv® trademark. Ultrafine TiO 2 has highly catalytic properties due to the relatively high surface area of each TiO 2 molecule. The principal use of ultrafine TiO 2 products is in NOx emission control products utilized in stationary, mobile and marine applications.

TABLE OF CONTENTS
In 2025, we generated $2.3 billion in revenue from sales of TiO 2.
Zircon
Zircon (ZrSiO4) is a co-product of mining mineral sands deposits for titanium feedstock. Zircon is used as an additive in ceramic glazes, which makes the ceramic glaze more water, chemical and abrasion resistant. It is also used for the production of zirconium metal and zirconium chemicals, in refractories, as molding sand in foundries, and for TV screen glass, where it adds its structural stability at high temperatures and resistance to abrasive and corrosive conditions. Zircon typically represents a relatively low proportion of the in-situ heavy mineral sands deposits we mine, but has a relatively high value compared to other heavy mineral products. Refractories containing zircon are expensive and are only used in demanding, high-wear and corrosive applications in the glass, steel and cement industries. Foundry applications use zircon when casting articles of high quality and value where accurate sizing is crucial, such as aerospace, automotive, medical, and other high-end applications.
In 2025, we generated $274 million in revenue from sales of zircon.
Other Products
High Purity Pig Iron
During the process of smelting ilmenite at our smelters to increase the concentration of titanium and produce titanium slag, high purity pig iron is produced as a co-product. High purity pig iron is used as a raw material in foundries for the production of high-quality ductile iron castings. Ductile iron is used extensively throughout the world for the production of safety critical automotive parts, such as engine blocks, brake calipers and steering knuckles in cars and trucks.
Monazite
Like zircon, monazite is a co-product of mining mineral sands deposits for titanium feedstock. Monazite is concentrated and processed to remove contaminants, such as uranium and thorium, before being sold to rare earth processors and separated into specific rare earth oxides (REOs) such as neodymium (Nd), praseodymium (Pr), terbium (Tb), and dysprosium (Dy). These REOs can then be metallized and formed into permanent magnets, particularly NdFeB magnets, that are needed to manufacture electric vehicle motors, wind turbines and other green economy applications.
Feedstock
Most TiO 2 products are derived from three naturally occurring minerals which are commonly referred to as heavy minerals or mineral sands: ilmenite, leucoxene and rutile. Ilmenite, rutile, leucoxene, as well as titanium slag and synthetic rutile which are processed from ilmenite, are the primary feedstock materials that we use for the production of TiO 2 pigment. Titanium slag is produced by smelting ilmenite in an electric arc furnace to separate titanium-oxide from the iron and other impurities. Synthetic rutile is produced by reducing ilmenite in a rotary kiln, followed by leaching under various conditions to remove the metallic iron from the reduced ilmenite grains. The purpose of both processes is to increase the titanium concentration of the ilmenite. There is substantial overlap amongst each of the aforementioned with the primary differentiating factor being the level of titanium content. For instance, rutile has the highest titanium dioxide content of approximately 94% to 96%, while ilmenite has the lowest of approximately 45% to 65%.
Titanium Tetrachloride
We sell titanium tetrachloride (“TiCl 4”) from our facilities in Thann, France and Yanbu, KSA. At our Thann facility in France, we produce TiCl 4 dedicated for merchant market sales to customers for use mainly in the production of various types of pigments and catalyst products. At our Yanbu facility, we produce excess TiCl 4 which we both sell directly to a joint venture between Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd. ("ATTM") for use at ATTM's titanium sponge plant facility that is adjacent to our Yanbu facility and in the merchant market.
In 2025, we generated $326 million in revenue from the sale of high purity pig iron, monazite, titanium tetrachloride and other products.
The demand for certain of our products during a given year is subject to seasonal fluctuations. See “Risk Factors –
Risks Relating to our Business - The markets for many of our products have seasonally affected sales patterns”.
Mining and Beneficiation of Mineral Sands Deposits
4

TABLE OF CONTENTS
Our current operational mining and beneficiation of mineral sands deposits are comprised of the following:
•KwaZulu-Natal (“KZN”) Sands operations located on the eastern coast of South Africa consisting of the Fairbreeze mine, a concentration plant, a mineral separation plant and two smelting furnaces that produce titanium slag;
•Our Namakwa Sands operations located on the western coast of South Africa consisting of the Namakwa mine, two concentration plants, a mineral separation plant, as well as two smelting furnaces that produce titanium slag;
•Our Northern Operations complex in Western Australia consisting of the Cooljarloo dredge mine and floating heavy mineral concentration plant and the Chandala metallurgical site which includes a mineral separation plant and a synthetic rutile plant that produces synthetic rutile;
•Eastern Australia operations consisting of the Atlas mine and a heavy mineral concentration plant located there and a mineral separation plant located at Broken Hill, New South Wales; and
•Perth Basin operations in Western Australia consisting of the Wonnerup mine and a mineral separation plant.
Zircon and monazite are often, but not always, found in mineral sands deposits containing ilmenite. They are extracted, alongside ilmenite and rutile, as part of the initial mineral sands separation process.
The mining of mineral sands deposits is conducted either “wet,” by dredging or hydraulic water jets, or “dry,” by using earth-moving equipment to excavate and transport the sands. The type of mining operation we deploy is dependent upon the characteristics of the ore body. Dredge mining is generally the favored method of mining mineral sands, provided that the ground conditions are suitable, water is readily available and the deposit is low in slime content. Dry mining techniques are generally preferred in situations involving hard ground, discontinuous ore bodies, small tonnage, high slimes contents and/or very high grades.
Regardless of the type of mining technique, the first step in the beneficiation process after the mineral sands have been mined is to utilize wet concentrator plants to produce a high grade of heavy mineral concentrate (typically approximately 90% to 98% heavy mineral content). Screened ore is first de-slimed, a process by which slimes are separated from larger particles of minerals, and then processed through a series of spiral separators that use gravity to separate the heavy mineral sands from lighter materials, such as quartz. Residue from the concentration process is pumped back into either the open pits or slimes dams for rehabilitation and water recovery.
After producing heavy mineral concentrate in our wet concentrator plants, we separate the non-magnetic (rutile, zircon and monazite) and magnetic (ilmenite) fractions utilizing a variety of techniques. Through the separation process, we produce zircon which is sold directly to customers, rutile and leucoxene which can immediately be used as feedstock material to make TiO 2 pigment, and monazite which we currently sell in a relatively unconcentrated form but which we plan on further processing before sale to extract greater value.
Ilmenite is generally further refined for use in our TiO 2 pigment manufacturing processes. Depending on the characteristics of the ilmenite we use two fundamental processes to refine ilmenite. Both processes involve the removal of iron and other non-titanium material.
•Titanium slag is made by smelting ilmenite in an electric arc furnace to separate titanium-oxide from the iron and other impurities. The result is two products: “slag” which contains 86% to 89% titanium dioxide and is considered a TiO 2 feedstock material, and high purity pig iron which is ready for sale to end-use customers.
•Synthetic rutile is made by reducing ilmenite in a rotary kiln, followed by leaching under various conditions to remove the iron from the reduced ilmenite grains. Activated carbon is a byproduct of this process. Our synthetic rutile has a titanium dioxide content of approximately 89% to 92% and is also considered a TiO 2 feedstock material.
Our current mining and beneficiation operations have an annual production capacity of approximately 832,000 metric tons (“MT”) of titanium feedstock, which is comprised of 182,000 MT of rutile and leucoxene, 240,000 MT of synthetic rutile and 410,000 MT of titanium slag. We currently have the capability to produce approximately 297,000 MT of zircon and 250,000 MT of pig iron per year.
Competitive Conditions of Mining and Feedstock Production
Globally, there are a large number of mining companies that mine mineral sand deposits containing ilmenite, as well as zircon. However, there is a smaller number of mining companies that are also involved in upgrading the underlying ilmenite to produce feedstock typically utilized by TiO 2 producers.
Pigment producers procure a range of types of feedstocks from multiple feedstock producers to create varying blends of feedstock materials that maximize the efficiency and economic returns of their unique production technique under conditions

TABLE OF CONTENTS
applicable at the time of production. Pigment producers frequently switch the relative amount of each feedstock they procure based on a number of factors including: the relative cost of feedstocks, feedstock logistics costs, the cost of, and availability of, chemicals used to process feedstocks, as well as waste management costs. Hence, there is a high degree of substitutability between and among titanium feedstocks.
Production of TiO 2 Pigment
TiO 2 pigment is produced using a combination of processes involving the manufacture of base pigment particles through either the chloride or sulfate process followed by surface treatment, drying and milling (collectively known as finishing). Currently, approximately 90% of our TiO 2 pigment production capacity is produced using the chloride process and approximately 10% of our TiO 2 production capacity is produced using the sulfate process.
We use the sulfate process at our manufacturing facility in Thann, France to produce ultrafine TiO 2 products.
In the chloride process, feedstock (slag, synthetic rutile, natural rutile or ilmenite ores) are reacted with chlorine (the chlorination step) and carbon to form TiCl 4 in a continuous fluid bed reactor. Purification of TiCl 4 to remove impurities is accomplished using selective condensation and distillation processes. The purified TiCl 4 is then oxidized in a vapor phase form to produce raw pigment particles and chlorine gas. The latter is recycled back to the chlorination step for reuse. Raw pigment is then typically slurried with water and dispersants prior to entering the finishing step. Due to the nature of the production process, the final pigment product is not sensitive to the feedstocks used to create it, as substantially all substances other than TiO 2 are removed during the process. The chloride process currently accounts for substantially all of the industry-wide TiO 2 production capacity in North America, and approximately 40% of industry-wide capacity globally.
In the sulfate process, ilmenite and/or slag are dissolved in concentrated sulfuric acid. After removing impurities, dissolved titanium is hydrolyzed and separated from the remaining sulfuric acid. The titanium hydrolysate is subsequently calcined in a rotary kiln to produce a raw TiO 2. The product is then further finished in a similar way to TiO 2 produced through the chloride process.
Commercial production of TiO 2 pigment results in one of two different crystal forms: rutile, which is manufactured using either the chloride process or the sulfate process, or anatase, which is only produced using the sulfate process. Rutile TiO 2 is preferred over anatase TiO 2 for many of the largest end-use applications, such as coatings and plastics, because its higher refractive index imparts better hiding power at lower quantities than the anatase crystal form and it is more suitable for outdoor use because it is more durable.
The primary raw materials used in the production of chloride TiO 2 pigment include titanium feedstock, chlorine and coke. As discussed above, we believe we are unique in the degree to which we produce our own high-grade titanium feedstock. Other chemicals used in the production of TiO 2 are purchased from various companies under short and long-term supply contracts. In the past, we have been, and we expect that we will continue to be, successful in obtaining extensions to these and other existing supply contracts prior to their expiration. We expect the raw materials purchased under these contracts, and contracts that we enter into the near term, to meet our requirements over the next several years.
Marketing of TiO 2
We supply and market TiO 2 under the brand name TIONA® and CristalActiv® to approximately 1,200 customers in approximately 120 countries, including market leaders in each of the key end-use markets for TiO 2, and we have supplied each of our top ten customers with TiO 2 for more than 10 years. We have implemented a margin stabilization program which we believe provides relative certainty over availability of product and price stability to customers who choose to participate, and have also initiated a long-term partnership strategy that we believe will strengthen the commitments from our customers across all regions and products. The long-term partnership strategy and margin stabilization programs are key parts of our TiO 2 marketing and sales strategy, enabling us to focus on predictability and reliability of TiO 2 delivery across the supply and demand cycle.
The following sets forth the percentage of our TiO 2 sales volume by end-use market for the year ended December 31, 2025:

TABLE OF CONTENTS
In addition to price and product quality, we compete on the basis of technical support and customer service. We sell our products through both a direct sales force and third-party agents and distributors. Our direct sales, marketing and technical service organizations execute our sales and marketing strategy on a global basis. Due to the technical requirements of TiO 2 applications, our technical service organization and direct sales offices are supported by a regional customer service staff located in each of our major geographic markets.
Our sales and marketing strategy focuses on aligning ourselves with customers growing faster than the market and effective customer management through the development and maintenance of strong relationships. We develop customer relationships and manage customer contact across multiple contact points within the organization including our sales, technical service and marketing, research and development, and customer service teams. These primary points of contact are supplemented by direct contact with plant operations personnel, supply chain specialists, and senior management. We believe that multiple points of customer contact facilitate efficient problem solving, supply chain support, formula optimization and co-development of products.
Competitive Conditions of TiO 2 Pigment
The global market in which our TiO 2 pigment business operates is highly competitive. Competition is based on a number of factors such as price, product quality and service. We face competition from both chloride process pigment producers and sulfate process pigment producers. Moreover, because transportation costs are minor relative to the cost of our product, there is also competition between products produced in one region versus products produced in another region.
We face competition from global competitors with headquarters in Europe, the United States and China, including Chemours, LB Group, Kronos Worldwide Inc., and INEOS. In addition, we compete with numerous regional producers particularly in Eastern Europe and China.
Research and Development
We have research and development facilities that aim to develop new products, service our products, and focus on applied research and development of both new and existing processes. The majority of scientists supporting our TiO 2 pigment product development and testing are located in Oklahoma City, Oklahoma, USA and Stallingborough, UK, while the majority of scientists supporting our TiO 2 ultrafine specialty business are located in Thann, France. In addition, the research and development personnel relating to our mineral sands operations are located in Australia and South Africa. Our research and development initiatives for concentration and separation of REOs is centered in Perth, Australia.
New process developments are focused on increased throughput, efficiency gains and general processing-related improvements for our customers. Ongoing development of process technology contributes to cost reduction, enhanced production flexibility, increased capacity, and improved consistency of product quality. Process technology research also pertains to concentration and separation of monazite into neodymium (Nd), praseodymium (Pr), terbium (Tb), and dysprosium (Dy), the types of REOs that are most in demand for EV and wind turbine applications.
During 2025, we commercialized several new products, including two new products to address both masterbatch and engineering resin markets. We also continued to focus on incorporating long-term sustainable solutions in our TiO2 products with

TABLE OF CONTENTS
the successful implementation of organic substitutions in several new product offerings. Moreover, with the closure of our Botlek pigment plant, we were able to successfully transfer certain technology to our Stallingborough pigment plant which we believe will enable us to maintain and grow our footprint in durable plastic pigment applications. We also continued to utilize our large global footprint by expanding the product capabilities at our Yanbu pigment plant which we believe will be able to efficiently and effectively service a broad array of geographic markets, including Europe.
In addition, we also continued to support our rare earth initiatives which resulted in improvements in the characterization and transformation of raw materials that could be used in the rare earth space. Tronox has also completed a pre-feasibility study with respect to the development of a rare earth "cracking and leaching" facility. Further development of this facility is expected to be conducted in 2026.
Patents, Trademarks, Trade Secrets and Other Intellectual Property Rights
Protection of our proprietary intellectual property is important to our business. At December 31, 2025, we held 67 patents and 3 patent applications in the U.S., and approximately 470 in foreign counterparts, including both issued patents and pending patent applications. Our U.S. patents have expiration dates ranging through 2043. Additionally, we have 11 trademark registrations in the U.S. and 3 trademark applications in the U.S., as well as 316 trademark counterpart registrations and applications in foreign jurisdictions.
We also rely upon our unpatented proprietary technology, know-how and other trade secrets. The substantial majority of our patents and trade secrets relate to our chloride products, surface treatments, chlorination expertise, and oxidation process technology, and this proprietary chloride production technology is an important part of our overall technology position. However, much of the fundamental intellectual property associated with both chloride and sulfate pigment production is no longer subject to patent protection. At Namakwa Sands, we rely on intellectual property for our smelting technology, which was granted to us in perpetuity by Anglo American South Africa Limited for use on a worldwide basis, pursuant to a non-exclusive license.
While certain of our patents relating to our products and production processes are important to our long-term success, more important is the operational knowledge we possess. We also use and rely upon unpatented proprietary knowledge, continuing technological innovation and other trade secrets to develop and maintain our competitive position. We conduct research activities and protect the confidentiality of our trade secrets through reasonable measures, including confidentiality agreements and security procedures. We protect the trademarks that we use in connection with the products we manufacture and sell, and have developed value in connection with our long-term use of our trademarks. See “Risk Factors—If our intellectual property were compromised or copied by competitors, or if competitors were to develop similar intellectual property, our results of operations could be negatively affected. Further, third parties may claim that we infringe on their intellectual property rights which could result in costly litigation."
Human Capital
Tronox employs approximately 5,700 people across six continents, and we believe it is our rich diversity and exceptional operational and technical expertise that, combined with our vertical integration model, position Tronox as the world's leading vertically integrated manufacturer of titanium dioxide pigment. Recognizing the importance of our human capital, one of our core strategies is to foster a high-performance culture in which we strive for zero harm and operational excellence, while harnessing technology and encouraging innovation to create value, all while empowering our people. In addition, we have placed a priority around developing leaders who will help us effectively (i) acquire, develop and nurture our talent, and (ii) foster a culture that embodies the values that are important to us, starting with safety and operating our business responsibly.
People
Because we operate both titanium ore mines and titanium dioxide pigment plants, and because our operations span the world, we require specialty skills in mining and TiO 2 pigment manufacturing. We also need people who are willing to learn skills across both mining and chemicals operations and who can help us extract value from our integrated model. The below map sets forth the approximate number of employees in each of the global regions in which we operate.

TABLE OF CONTENTS
In January 2026, the Company announced its intent to permanently close its TiO 2 plant in Fuzhou, China which will impact approximately 550 employees in that region.
Accordingly, we place a high priority on knowledge transfer, including, but not limited to, by relocating skilled leaders across countries and between mining and TiO 2 pigment operations, by staffing high-potential employees in regions on global projects, and by enabling collaboration in global centers of excellence). We are committed to creating an organization where leaders encourage a diverse workforce, where people feel valued and respected, have access to opportunities, and in which a variety of different voices are encouraged and heard. For instance, during 2025, we focused our efforts on inclusion through developing learning opportunities and surveying our employees. In addition, in 2025, we focused on, among other things, promoting women in STEM and celebrating our different cultures through local events.
We also place an uncompromising focus on operating safe, reliable, and responsible facilities, and we measure our progress with both safety metrics and leading indicators. We believe every employee and contractor has a responsibility for safety, and we proactively identify and manage risk, conduct ourselves responsibly, exercise good judgment, and take accountability for our actions. In 2025, our employees worked approximately 11 million hours with 11 recordable injuries and no fatalities from our operations, and our contractors worked approximately 12 million hours with 16 recordable injuries and no fatalities from our operations.
Culture
We aim to create an organizational culture where employees unleash their full value through living our values, and fostering a high-performance culture. In 2025, we developed a program, Living our Values, which we expect to launch in 2026. Through this program, employees will learn how they can live our values in everything they do. In addition, such program will emphasize employees working with a Growth Mindset where we believe everyone can improve, feedback is a gift, and challenges are an opportunity to learn. We believe we can have the most success fostering a high performance culture by setting high expectations for each other and modelling ways of work done well, enrolling our people into fulfilling our vision and strategy, and investing in the success and fulfillment of our people.
Today, we are a collaborative group of people who naturally want to be helpful to others, and we adjust our own efforts to make our colleagues’ work easier, however we can.
We have adopted a set of core values that describes our expectations of one another, starting with safety. Every performance review starts with a self-assessment and manager’s assessment of our consistency in living our values. Employees are encouraged – and provided a toolkit – to develop in the values where they are weak, and to help coach others in the values where they are strong.

Capabilities
At Tronox we lead with safety. To ensure we live this value with impact, a key focus of our strategy is to drive risk reduction with an updated safety program focused on leading indicators. This program is intended to help find areas for the Company to make improvements and make our business safer with initiatives that would not be accomplished otherwise. In 2025, we completed numerous projects aimed at reducing risk and increasing workplace pride which we believe will make our operations safer.
In addition, our employees are further guided by our code of conduct and business ethics and we conduct annual global training to help them fully understand and comply with our code of conduct.
We also have a rigorous succession planning process with respect to key positions throughout the organization. We believe such process allows us to proactively develop the talent of the future and allows us to move with speed and agility when leadership changes are required. As part of the succession planning process, high potential leaders are identified and development plans are completed for each candidate.
Sustainability
Our business requires an unwavering focus on sustainable operating practices, and our commitment to sustainability supports our overall vision to be the leader in shaping a sustainable, thriving world through enriched and refined minerals and a key pillar of our strategy to be the benchmark for sustainability. As such, we integrate sustainability into every aspect of our business—from our culture and our strategy to our operating practices. We believe sustainable operations enable us to better control costs and manage our environmental footprint. Sustainability also encompasses providing our employees with a safe, diverse workplace and offering them opportunities to grow and develop. Ultimately, safe, environmentally sustainable operations demonstrates our respect for our communities and supports our continued privilege to operate.
Our sustainability efforts are also focused on reducing Tronox’s carbon footprint. Our detailed and actionable roadmap for reducing carbon emissions in the short-, medium- and long-term demonstrates Tronox’s commitment to mitigating the impact of climate change. Our roadmap covers 100% of our operations and is based on a thorough analysis of our carbon footprint and step-by-step plans to reduce it. The majority of our greenhouse gas ("GHG") emissions are generated from our TiO 2 slag furnaces in South Africa, synthetic rutile kiln in Western Australia, and TiO 2 pigment plants in the United States, United Kingdom, France, Brazil, Australia, and the Kingdom of Saudi Arabia.
We are proud that we achieved our previously announced target to reduce Scope 1 and Scope 2 emission intensity 25% by the end of 2025 against a 2019 baseline. In addition, we are continuing to actively progress GHG reduction plans to enable us to achieve our target of a 50% reduction by the end of 2030 also against a 2019 baseline. During 2025, we were able to realize the full benefits of the 200 MW solar energy project in South Africa which contributed to approximately 40% of our South African electricity needs. The project is expected to reduce Tronox's global Scope 1 and 2 emissions by approximately 13%. In addition, in June 2024, we announced a second large-scale renewable energy project in South Africa that is expected to be fully operational by the end of 2027. Upon completion of such project, the Company expects that approximately 70% of its South African needs will be satisfied by renewable energy. It remains our long-term goal to achieve "net zero" carbon emissions by 2050. We believe the Company's dedication to these significant renewable energy projects are just two examples of how Tronox is committed to being a leader when it comes to corporate sustainability and protection of the environment.
Environmental, Health and Safety Authorizations
Mining
Our facilities and operations are subject to extensive general and industry-specific environmental, health and safety regulations in jurisdictions where we operate, but particularly South Africa and Australia. These regulations include those relating to mine rehabilitation, liability provision, water management, the handling and disposal of hazardous and non-hazardous materials, and occupational health and safety. The various legislation and regulations are subject to a number of internal and external audits. We believe our mineral sands operations are in compliance, in all material respects, with existing health, safety and environmental legislation and regulations.

TABLE OF CONTENTS
Regulation of the Mining Industry in South Africa
The South African mining regulatory regime is comprehensive and requires regular reporting to applicable government departments. A failure to, among other things, comply with any such reporting requirements or the conditions of any mining license could result in extended mandatory shutdown periods, license and/or mining right suspensions or revocations all of which could impact our business.
In South Africa, the primary legislative enactments with which our mines are required to comply are the Mineral and Petroleum Resources Development Act (“MPRDA”) which governs the acquisition and retention of prospecting and mining rights. In addition, the Mine Health and Safety Act governs the manner in which mining must be conducted from a health and safety perspective, while the National Environmental Management Act (and its subsidiary legislation) provides the underlying framework with respect to environmental rules and regulation for which our operations must comply. For additional details regarding other South African legislative enactments that govern our mining licenses please see the section entitled “Risk Factors” set forth elsewhere in this Form 10-K.
Regulation of the Mining Industry in Australia
Each Australian state and territory has its own legislation regulating the exploration for and mining of minerals. Our key exploration and mining operations are regulated by the Mining Act 1978 (WA), the Mining Act 1992 (NSW) and their related regulations.
In Western Australia, State Agreements are contracts between the State and the proponents of major resources projects within Western Australia, and are intended to foster resource development and related infrastructure investments. These agreements are approved and ratified by the Parliament of Western Australia. The State Agreement relevant to the development of certain of our Western Australian operations is the agreement authorized by the Mineral Sands (Cooljarloo) Mining and Processing Agreement Act 1988 (WA). This agreement concluded in March 2020 and Tronox's rights and obligations are now covered by the Western Australian Mining Act.
Regulation of Finished Product Manufacturing
Our business is subject to extensive regulation by federal, state, local and foreign governments. Governmental authorities regulate the generation and treatment of waste and air emissions at our operations and facilities. At many of our operations, we also comply with worldwide, voluntary standards developed by the International Organization for Standardization (“ISO”), a nongovernmental organization that promotes the development of standards and serves as a bridging organization for quality and environmental standards, such as ISO 9002 for quality management and ISO 14001 for environmental management.
Chemical Registration
As a chemical manufacturer with global operations, we are subject to a wide array of regulations regarding the import, export, labelling, use, storage and disposal of our products. We are obliged to comply with the regulation of chemical substances and inventories under the Toxic Substances Control Act in the United States and the Registration, Evaluation and Authorization of Chemicals (“REACH”) regulation in Europe, as well as a growing list of analogous regimes in other parts of the world, including China, South Korea and Taiwan. Manufacturers and importers of chemical substances must register information regarding the properties of their existing chemical substances with the European Chemicals Agency (“ECHA”). REACH regulations require chemical substances which are newly imported or manufactured in the EU to be registered before being placed on the market, assessed for human health or environmental risk and for registrations to be updated periodically such as when new information emerges relevant to human health or environmental risks associated with the production or use of the substance. For additional information on this topic, see section entitled "Risk Factors - Risks Relating to our Legal and Regulatory Environment - Our TiO 2 products are subject to increased regulatory scrutiny that may impede or inhibit widespread usage of TiO 2 and / or diminish the Company's ability to sustain or grow its business or may add significant costs of doing business."
Greenhouse Gas Regulation
Globally, our operations are subject to regulations that seek to reduce emissions of GHGs. We currently report and manage GHG emissions as required by law for sites located in jurisdictions requiring such managing and reporting of GHGs, primarily the European Union, United Kingdom and Australia. For additional information on this topic, see section entitled “Risk Factors – Risks Relating to our Legal and Regulatory Environment - Sustainability issues as they may be applicable in certain jurisdictions, including those related to climate change, may subject us to additional costs and restrictions, including increased energy and raw material costs, which could have an adverse effect on our business, financial condition and results of operations, as well as damage our reputation.”

Item 1A. Risk Factors
You should carefully consider the risk factors set forth below, as well as the other information contained in this Form 10-K, including our consolidated financial statements and related notes. This Form 10-K contains forward-looking statements that involve risks and uncertainties. Any of the following risks could materially and adversely affect our business, financial condition and results of operations. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition and results of operations. The following risk factors are not necessarily presented in order of relative importance and should not be considered to represent a complete set of all potential risks that could affect our business, financial condition and results of operations.
RISKS RELATING TO OUR BUSINESS
Market conditions, as well as global and regional economic downturns that adversely affect the demand for our end-use products, could adversely affect the results of our operations and the prices at which we can sell our products, thus, negatively impacting our financial results.
Our revenue and results of operations are significantly dependent on sales of TiO 2 products and zircon. Demand for these products historically have been linked to global, regional and local GDP and discretionary spending, which can be negatively impacted by regional and world events or economic and market conditions. Such events can cause a decrease in demand for our products and market prices to fall, which may have an adverse effect on our results of operations and financial condition. A substantial portion of our products and raw materials are commodities that reprice as market supply and demand fundamentals change, and we have recently been experiencing a depressed trend in the commodity cycle for TiO 2. Accordingly, product margins and the results of operations tend to vary with changes in the business cycle.
A significant portion of the demand for our TiO 2 products comes from manufacturers of paint and plastics. A significant portion of the demand for zircon comes from the construction and other industrial end markets. Our customers may experience significant fluctuations in demand for their own end products because of economic conditions, changes in consumer demand, or increases in raw material and energy costs. In addition, with respect to the zircon market, we believe that China currently accounts for approximately 50% of the world’s demand for zircon. However, there is currently a weakening demand in the domestic Chinese ceramics end-market as well as an increase in domestic Chinese zircon sand production, partially attributable to the Chinese continued focus on mining rare earth bearing minerals, which is adding to the global zircon supply. A prolonged economic downturn in China could result in reduced zircon and TiO 2 demand in China as well as Chinese domestic zircon producers increasing exports of zircon at low prices which could have a material adverse effect on our business and financial results.
The price of our products, in particular, TiO 2, zircon, and pig iron, have been, and in the future may be, volatile. Price declines for our products will negatively affect our financial position and results of operations.
Historically, the global market for TiO 2, zircon and pig iron have been volatile, and those markets are likely to remain volatile in the future. Prices for TiO 2, zircon and pig iron may fluctuate in response to relatively minor changes in the supply of,

TABLE OF CONTENTS
and demand for, these products, market uncertainty and other factors beyond our control, and we have recently been experiencing a depressed trend in the commodity cycle for TiO 2. Factors that affect the price of our products include, among other things:
•overall economic conditions;
•the level of customer demand particularly in the paint, plastics and construction industries;
•the level of production and exports of our products globally, including the impact of competitors increasing their capacity and exports, in particular Chinese competitors, as well as the price of such exports being offered to customers at lower prices;
•the level of production and cost of materials, such as chlorine, sulfuric acid, sulfur, and anthracite, used to produce our products, including rising prices of raw materials due to inflation;
•the cost of energy consumed in the production of TiO 2, feedstock and zircon, including the price of natural gas, pet coke and electricity, in particular, the increasing electricity costs relating to our South African operations;
•domestic and foreign governmental regulations, tariffs or other trade disputes, regulations and taxes;
•political conditions or hostilities and unrest in regions where we manufacture and/or export our TiO 2, zircon and feedstock/other products; and
•major public health issues which could cause, among other things, macroeconomic disruptions.
Pricing pressure, along with demand fluctuations, with respect to our TiO 2 products, zircon and pig iron can make it difficult to predict the cash we may have on hand at any given time, and a continued period of price declines and/or demand declines may materially and adversely affect our financial position, cash generation, liquidity, ability to service and repay our debt, pay dividends, operate our business, fund our liquidity and capital needs, including through the capital markets and for the purpose of financing planned capital expenditures and results of operations.
Our industry and the end-use markets in which we compete are highly competitive and are characterized by excessive production capacity, particularly in China. Competition and excess production capacity may adversely affect our results of operations and operating cash flows.
Each of our markets is highly competitive. Competition in the TiO 2 industry is based on a number of factors such as price, product quality, and service. We face significant competition from major international and smaller regional competitors, especially producers in China. Chinese producers have significantly expanded their TiO 2 production capacity in recent years and the volume of their exports and certain Chinese producers have also publicly announced their intention to continue to expand their TiO 2 production capacity and aggressive exports efforts. Moreover, the increased Chinese TiO 2 production capacity, along with the prolonged economic downturn in China, is resulting in increasing quantities of TiO 2 being exported to other regions of the world in which we compete typically at lower prices.
We compete with a large number of mining companies with respect to zircon. Zircon producers generally compete on the basis of price, quality, logistics, delivery, payment terms and consistency of supply. Moreover, increased Chinese production of zircon from both heavy mineral concentrates imported from Africa and Australia, and the mining of monazite to support the Chinese domestic rare earth industry, along with the prolonged economic downturn in China, is resulting in increasing quantities of zircon being exported by China to other regions of the world in which we compete typically at lower prices.
In addition, we face substantial risk that our customers could switch to our competitors’ products in response to any number of developments including lower price offerings by our competitors for substantially the same products, new product development by competitors, or with respect to zircon customers, switching to lower priced substitute products. Our inability to develop, produce or market our products to compete effectively against our competitors could have a material adverse effect on our business, financial condition, results of operations and cash flow.
Although certain jurisdictions have imposed anti-dumping duties or similar duties against TiO 2 imports from China, there can be no assurance that such duties will benefit our business, and if such duties are reduced, removed or not extended, it could have a material adverse effect on our results of operations and financial position.
The European Commission, Brazil, India, and the Kingdom of Saudi Arabia have imposed definitive anti-dumping duties on the importation of TiO 2 products originating in China. The anti-dumping duties imposed by the European Commission in January 2025 will remain in effect for an initial period of five years until January 2030 with the possibility of an extension for an additional five years. The anti-dumping duties imposed by Brazil’s Chamber of Foreign Trade in October 2025 are also definitive and will be in place for an initial period of five years until October 2030 with the possibility of an extension for an additional five years. The antidumping duties imposed by the Kingdom of Saudi Arabia in October 2025 will also be in place for an initial period
13

TABLE OF CONTENTS
of five years until October 2030 with the possibility of an extension for an additional five years. The Indian anti-dumping duties became definitive in May 2025, but such duties were stayed by an Indian state court due to perceived procedural issues. Although we believe such definitive duties will ultimately be reinstated, we cannot predict when such duties will be reinstated, or if they will be reinstated at all. If reinstated, the Indian duties will also have the possibility of an extension for an additional five years when they expire in May 2030.
We may benefit from these duties due to the impact they may have on the price at which Chinese importers sell TiO 2 in these jurisdiction as well as on the volume of exports of Chinese-made TiO 2 to these jurisdictions. However, there can be no assurance that these duties will prove effective in increasing the price at which such Chinese producers sell TiO 2 in the jurisdictions that have or will impose anti-dumping duties nor in decreasing the volume of TiO 2 sold by Chinese exporters. In addition, Chinese TiO2 producers are also increasingly looking for alternative ways to evade such anti-dumping duties, including through the acquisition of non-Chinese TiO2 pigment plants. Any of these outcomes could have a material adverse effect on our results of operations and financial position. Anti-dumping duties are generally subject to periodic reviews and, occasionally, legal challenges, which can result in their revocation, suspension or reduction. If these anti-dumping duties and tariffs were to be revoked or reduced in the future, or if they do not adequately combat China’s unfair trade practices, our results of operations and financial position could be adversely impacted.
We also benefit from the duties issued by the U.S. government pursuant to Section 301 of the Trade Act of 1974 on Chinese-origin TiO 2 products, which are currently set at 25% (“Section 301 Duties”). Similar to anti-dumping duties, these duties impact the volume and price of Chinese TiO 2 products originating in China imported into the United States. Section 301 Duties may be modified, removed, extended, reduced or increased by executive action, or TiO 2 could be excluded from the Section 301 Duties in the future. Any such changes to the Section 301 Duties on TiO 2 products could have a material adverse effect on our results of operations and financial position.
An increase in the price of energy or other raw materials, or an interruption in our energy or other raw material supply, could have a material adverse effect on our business, financial condition and results of operations.
Our mining, beneficiation, smelting and production processes consume significant amounts of energy and raw materials, the costs of which can be subject to worldwide, as well as, local supply and demand, as well as other factors beyond our control. Fuel and energy linked to commodities, such as diesel, natural gas, heavy fuel oil and pet coke, and other consumables, such as chlorine, sulfuric acid, illuminating paraffin, electrodes, sulfur and anthracite, consumed in our TiO 2 manufacturing and mining operations form an important part of our TiO 2 operating costs. We have no control over the costs of these consumables, many of which are linked to some degree to the price of oil, and the costs of many of these raw materials may fluctuate widely for a variety of reasons, including changes in availability, major capacity additions or reductions, or significant facility operating problems. In addition, certain key raw materials used in our operations are currently primarily sourced from China so any export restrictions or limits imposed by the Chinese government on such raw materials could have a material adverse effect on our operations. Moreover, the ongoing Russia and Ukraine conflict has resulted in, and may continue to result in, increased uncertainty with respect to the supply of energy and other energy-dependent commodities for our TiO 2 production facilities located in the European Union and the United Kingdom, as well as other raw materials, such as anthracite, for our slag furnaces located in South Africa. Increased costs of electricity and disruptions in the supply of electricity due to long-standing operational issues at the sole, state-owned energy supplier in the Republic of South Africa, Eskom, could increase the costs of production, or disrupt operations, at our mines and beneficiation operations in that country. Availability of such consumables could also be impacted by transportation capacity constraints or other interruptions. These fluctuations could negatively affect our operating margins, our results of operations or planned capital expenditures. In addition, due to our global footprint and reliance on key raw materials from around the world, we are particularly reliant on shipping vessels to transport such raw materials as well as our finished goods. If the costs of raw materials, utilities, transportation and similar costs rise, our operating expenses will increase and could adversely affect our business, especially if we are unable to pass price increases relating to raw materials, utilities, transportation and similar costs through to our customers.
The markets for many of our products have seasonally affected sales patterns.
Historically, the demand for our products is subject to seasonal fluctuations. TiO 2 is widely used in paint and other coatings where demand increases prior to the painting season in the Northern Hemisphere (spring and summer). Additionally, although zircon is generally a non-seasonal product, it is negatively impacted by the winter and Chinese New Year celebrations due to reduced zircon demand from China. We may be adversely affected by existing or future cyclical changes, and such conditions may be sustained or further aggravated by anticipated or unanticipated changes in regional weather conditions. For example, poor weather conditions in a region can lead to an abbreviated painting season, which can depress consumer sales of paint products that use TiO 2.

TABLE OF CONTENTS
We are dependent on, and compete with other mining and chemical businesses for, key human resources in the countries in which we operate, and our business will suffer if we are unable to hire or deploy highly skilled employees.
We compete with other chemical and mining companies, and other companies generally, in the countries in which we operate to attract and retain key human resources at all levels with the appropriate technical skills and operating and managerial experience necessary to continue operating and expanding our businesses. These operations use modern techniques and equipment and accordingly require various types of skilled workers. The success of our business will be materially dependent upon the skills, experience and efforts of our key officers and skilled employees. Competition for skilled employees may cost us in terms of higher labor costs or reduced productivity. In addition, certain of our production facilities and mining operations are situated in remote locations which may make it more difficult to attract and retain the skilled workers required. As a result, we may not be able to attract, retain and deploy skilled and experienced employees. Should we lose any of our key personnel or fail to attract, retain and deploy key qualified personnel or other skilled employees, our business may be harmed and our operational results and financial condition could be affected.
Given the nature of our chemical, mining and smelting operations, we face a material risk of liability, production delays and additional expenditures from industrial accidents.
Our business is exposed to, among other things, industrial accidents the occurrence of which could delay production, suspend operations, increase repair, maintenance or medical costs and, due to the vertical integration of our operations, could have an adverse effect on the productivity and results of operations of a particular manufacturing facility or on our business as a whole. Furthermore, during operational breakdowns resulting from any such industrial accident, the relevant facility may not be restored to full operations within the anticipated timeframe, which could result in further business losses. Over our operating history, we have incurred incidents of this nature. If any of the equipment on which we depend were severely damaged or were destroyed by fire or otherwise, we may be unable to replace or repair it in a timely manner or at a reasonable cost, which would impact our ability to produce and ship our products, which would have a material adverse effect on our business, financial condition and results of operations.
Equipment failures and deterioration of assets may lead to production curtailments, shutdowns or additional expenditures.
Our operations depend upon critical equipment that must be periodically maintained and upgraded in order to avoid suffering unanticipated breakdowns or failures. The occurrence of equipment failures or deterioration of assets could delay production, suspend operations, increase repair, maintenance or medical costs and, due to the vertical integration of our operations, could have an adverse effect on the productivity and results of operations of a particular manufacturing facility or on our business as a whole. In addition, assets critical to our mining and chemical processing operations may deteriorate due to wear and tear or otherwise sooner than we currently estimate. Such deterioration may result in additional maintenance spending and additional capital expenditures. If these assets do not generate the amount of future cash flows that we expect, and we are not able to refurbish them or procure replacement assets in an economically feasible manner, our future results of operations may be materially and adversely affected.
Our results of operations and financial condition could be seriously impacted by security breaches, including cybersecurity incidents.
We rely on information technology systems across our operations to manage our business including, but not limited to, our accounting, finance, and supply chain functions. Our information technology is provided by a combination of internal and external services and service providers. Further, our business involves the use, processing, storage and transmission of information about customers, suppliers and employees using such information technology systems. Our ability to effectively operate our business depends on the security, reliability and capacity of these systems.
Like most major corporations, during the normal course of business, we have been the target of cyberattacks, including phishing or ransomware attacks, from time to time, and we expect to be the target of such cyberattacks in the future. For instance, the Cristal business we acquired in April 2019 was subject to a significant cybersecurity attack in 2017. Failure to effectively prevent, detect and recover from security breaches, including attacks on information technology and infrastructure by hackers; viruses; breaches due to employee error or actions; or other disruptions could seriously harm our operations as well as the operations of our customers and suppliers. Such serious harm can involve, among other things, misuse of our assets, business disruptions, loss of data, unauthorized access to trade secrets and confidential business information, unauthorized access to personal information, legal claims or proceedings, reporting errors, processing inefficiencies, negative media attention, reputational harm, loss of sales, remediation and increased insurance costs, and interference with regulatory compliance. We have experienced, and expect to continue to experience, these types of cybersecurity threats and incidents, which may be material.
15

TABLE OF CONTENTS
We have put in place training and security measures designed to protect against cyberattacks, phishing, security breaches and misappropriation or corruption of our systems, intentional or unintentional disclosure of confidential information, or disruption of our operations. As these threats continue to evolve, particularly around cybersecurity, we may be required to expend significant resources to enhance our control environment, processes, practices and other protective measures. Despite these efforts, we may not be able to prevent cyberattacks and other security breaches and such events could materially adversely affect our business, financial condition and results of operations.
Our ore resources and reserve estimates are based on a number of assumptions, including mining and recovery factors, future cash costs of production and ore demand and pricing. As a result, ore resources and reserve quantities actually produced may differ from current estimates.
The mineral resource and reserve estimates are estimates of the quantity and ore grades in our mines based on the interpretation of geological data obtained from drill holes and other sampling techniques, as well as from feasibility studies. The accuracy of these estimates is dependent on the assumptions and judgments made in interpreting the geological data in accordance with established guidelines and standards. Our mineral reserves represent the amount of ore that we believe can be economically mined and processed, and are estimated based on a number of factors.
There is significant uncertainty in any mineral reserve or mineral resource estimate. Factors that are beyond our control, such as the ability to secure mineral rights, the sufficiency of mineralization to support mining and beneficiation practices and the suitability of the market may significantly impact mineral resource and reserve estimates. The actual deposits encountered and the economic viability of mining a deposit may differ materially from our estimates. Since these mineral resources and reserves are estimates based on assumptions, we may revise these estimates in the future as we become aware of new developments. To maintain TiO 2 feedstock and zircon production beyond the expected lives of our existing mines or to increase production materially above projected levels, we will need to access additional reserves through exploration or discovery.
If we are unable to innovate and successfully introduce new products, or new technologies or processes reduce the demand for our products or the price at which we can sell products, our results of operations could be adversely affected.
Our industries and the end-use markets into which we sell our products experience periodic technological change and product improvement. Our financial condition and results of operations could be adversely affected if we are unable to gauge the direction of commercial and technological progress in key end-use markets or if we fail to fund and successfully develop, manufacture and market products in such changing end-use markets.
In addition, new technologies or processes have the potential to replace or provide lower-cost alternatives to our products, such as new processes that reduce the amount of TiO 2 or zircon content in consumer products which in turn could depress the demand and pricing for TiO 2 or zircon, respectively. We cannot predict whether technological innovations will, in the future, result in a lower demand for our products or affect the competitiveness of our business. We may be required to invest significant resources to adapt to changing technologies, markets and competitive environments.
The Company may not be successful in arranging required financing and/or developing a financeable structure for its rare earth initiatives, and even if the required financing is obtained and/or a financing structure is achieved, the Company may not be successful in developing a viable rare earth supply chain.
The Company's ability to successfully implement its rare earth initiatives is contingent upon arranging adequate financing and/or structuring a financeable model. In 2025, for example, we received coordinated, non-binding and conditional letters of support / interest from Export Finance Australia and Export-Import Bank of the United States, respectively, for up to an aggregate of $600 million in limited or non-recourse financing to support the development of Tronox's rare earth supply chain. There can be no assurance that the required funding will be available on acceptable terms - or at all - or that the Company will be able to satisfy any conditions imposed by potential governmental agencies or other third-party lenders, investors, or partners, including without limitation as to structuring. Additionally, the Company's plans to develop a rare earth supply chain outside of China, in particular in the US and Australia, depend on numerous uncertain factors, including but not limited to, the outcomes of pre-feasibility studies, negotiations with third parties, access to processing and infrastructure, regulatory approvals, favorable market demand, availability of skilled personnel, and geopolitical considerations. Failure to secure the necessary funding or to achieve progress in developing such supply chains and structuring could materially adversely affect the Company's ability to meaningfully develop a rare earth business. In addition, historically, the Company has sold the monazite contained in its mines in unconcentrated form as a waste product rather than processing it into rare earth oxide, and the Company has no experience in managing a standalone rare earth business. There can be no assurance that the Company will be successful in this regard.
RISKS RELATING TO THE GLOBAL NATURE OF OUR BUSINESS
16

TABLE OF CONTENTS
We are exposed to the risks of operating a global business.
We have operations in jurisdictions around the globe which subjects us to a number of risks, including:
•adapting to unfamiliar regional and geopolitical conditions and demands, including political instability, civil unrest, expropriation, nationalization of properties by a government, imposition of sanctions, changes to import or export regulations and fees, renegotiation or nullification of existing agreements, mining leases and permits;
•increased difficulties with regard to political and social attitudes, laws, rules, regulations and policies within countries that favor domestic companies over non-domestic companies, including customer- or government-supported efforts to promote the development and growth of local competitors;
•economic and commercial instability risks, including those caused by sovereign and private debt default, corruption, and new and unfamiliar laws and regulations at national, regional and local levels, including taxation regimes, tariffs and trade barriers, including any additional tariffs in the United States or retaliatory tariffs imposed by other governments, exchange controls, repatriation of earnings, and labor and environmental and health and safety laws and regulations;
•implementation of additional technological and cybersecurity measures and cost reduction efforts, including restructuring activities, which may adversely affect our ability to capitalize on opportunities;
•major public health issues which could cause, and have caused, disruptions in our operations or workforce;
•war, political conditions, hostilities, including, but not limited to, the ongoing Russia and Ukraine and Middle East conflicts, or terrorist activities;
•difficulties enforcing intellectual property and contractual rights in certain jurisdictions; and
•unexpected events, including fires or explosions at facilities, and natural disasters, including as a result of climate-related events.
South Africa, where we have large mining assets and derive a significant portion of our revenue and profit, poses distinct operational risks which could affect our business, financial condition and results of operations.
In South Africa, we currently operate two significant mining assets, as well as accompanying separation plants and smelting operations, and derive a significant portion of our profit from the sale of zircon. Our mining and smelting operations depend on the electrical grid operated by Eskom, the sole-state-owned energy supplier, as well as the electrical power generated by Eskom. In the past, Eskom has not been able to reliably provide electrical power and there is no assurance that such reliability of electrical power and the associated energy grid will continue in the future which could have a material adverse effect on our business, financial condition and results of operations. In addition, we have also recently experienced increased electricity prices in South Africa and although we have been trying to reduce our dependency on Eskom through the use of renewable energy sources, there can be no assurance that we will be able to effectively mitigate any future electricity prices that are expected to occur in the future. If Eskom continues to increase the price of electricity in the future and we are unable to effectively mitigate such prices it could have a material adverse effect on our business, financial condition and results of operations.
Our operations in South Africa are reliant on services provided by the State-owned, sole provider of rail transport, Transnet Freight Rail and ocean transport, Transnet National Port Authority (collectively "Transnet"). Furthermore, Transnet provides extensive dockside services at both the ports of Richards Bay and Saldanha Bay from where we export bulk quantities of TiO 2 feedstock to our pigment plants worldwide and pig iron. Like Eskom, Transnet faces chronic operational and financial challenges. In the past, the Port of Richards Bay, which is owned and operated by Transnet, was impacted by two separate events, including a significant fire, which damaged part of the Port's infrastructure, causing increased shipment delays and costs to us. Currently, Transnet's rail transport services at the Port of Richards Bay is not operational, and as such, we are presently using trucking services to transport all of our raw material from our KZN operations to the port of Richards Bay. Shipment delays at the port of Richards Bay have persisted for the last several years, including 2025, and we believe such delays will continue in 2026 and beyond. Delays or interruptions at either the rail service or the ports in which we receive and/or export material could have a negative impact on our business, financial condition and results of operations.
In addition, our KZN Sands operations currently use approximately 316,000 gigajoules of Sasol gas annually, which is currently available only from Sasol Limited (Sasol). As such, an interruption in the supply of gas from Sasol could have a material adverse effect on our business, financial conditions and results of operations.
In addition, under South African law, our South African mining operations are subject to various environmental authorizations that govern each operation. These authorizations require, among other conditions, that mining operations maintain certain environmental standards, including air and water quality limits and post-rehabilitation obligations. Any changes by governmental authorities to these limits and license conditions could increase our costs of operations thereby affecting our operational results and financial condition.

TABLE OF CONTENTS
The aforementioned operational risks, as well as any other foreseen or unforeseen operational risks primarily related to doing business in South Africa, could have a material adverse effect on our business, financial condition and results of operations.
As an emerging market, South Africa poses a challenging array of long-term political, social and economic risks.
South Africa continues to undergo political, social and economic challenges. South Africa has also experienced instances of civil unrest which resulted in significant damage to the national supply chains and logistics. The area near our KZN operations is one of the areas in which such unrest has occurred. Changes to, or instability in, the economic, social or political environment in South Africa which cause civil unrest, shortages of production materials, interruptions to transportation networks, or labor unrest could result in production delays and production shortfalls, and materially impact our production and results of operations.
The South African government has recently embarked on a process of identifying and securing land for persons who were previously dispossessed of such land as a result of Apartheid policies. For instance, the South African government has released a draft land expropriation bill which contemplates that, where it is in the “public interest”, land may be expropriated by the South African government, without compensation being payable to the current owners. While the South African government has indicated that such measures will be applied initially to state-owned land, it is possible that such measures may extend to agricultural and mining areas. In the event that the land on which the Namakwa Sands and KZN Sands operations are situated become the subject of a land claim under any such proposed or future land expropriation bill, it may have a material adverse effect on our business, financial condition and results of operations.
The South African government's exchange control regulations require resident companies to obtain the prior approval of the South African Reserve Bank to raise capital in any currency other than the Rand, and restrict the export of capital from South Africa. While the South African government has relaxed exchange controls in recent years, it is difficult to predict whether or how it will further change or abolish exchange control measures in the future. These exchange control restrictions could hinder our financial and strategic flexibility, particularly our ability to use South African capital to fund acquisitions, capital expenditures, and new projects outside of South Africa.
Our South African operations have been affected by inflation in South Africa in recent years. Employment costs and wages in South Africa have increased in recent years, resulting in significant cost pressures for the mining industry. Prolonged or heightened inflation and associated cost pressures could have a material adverse effect on our business, financial condition and results of operations.
Our South African operations have entered into various collective agreements with organized labor regulating wages and working conditions at our mines and smelter operations. There have been periods when various stakeholders have been unable to agree on dispute resolution processes, leading to threats of disruptive industrial action disputes. Due to the high level of employee union membership, our South African operations are at risk of production stoppages for indefinite periods due to strikes and other labor disputes. Although we believe that we have good labor relations with our South African employees, we may experience labor disputes in the future.
In addition, although we believe that our relationships with our various local communities are good, the areas in which our South African operations are situated are the traditional homelands of various tribal groupings that are historically politically volatile. This volatility persists today and frequently results in violent, destructive behaviors. In addition, the physical security situation continues to deteriorate and we have been the victim of immaterial theft and are aware that other industrial mining operations near ours are frequently the target of sophisticated mineral syndicates capable of stealing industrial minerals on a relatively large scale. Increased volatility, related civil unrest and further deterioration in the security situation may result in production stoppages and/or the destruction and theft of assets, any of which could have a material adverse effect on our business, financial condition and results of operations.
Political and social instability, and unrest, and actual, or potential, armed conflicts in the Middle East region may affect the Company's results of operations and financial position.
Our operations in KSA have been affected in the past, and may be affected in the future, by political, social and economic conditions from time to time prevailing in, or affecting, KSA or the wider Middle East region, including by rocket attacks from armed rebel groups. For example, since 2011, a number of countries in the Middle East region have witnessed, and are currently witnessing, significant social unrest, including widespread public demonstrations, and, in certain cases, armed conflict, terrorist attacks, diplomatic disputes, foreign military intervention and a change of government. In addition, in the recent past there have been a number of attacks related to the conflicts in the Middle East on commercial shipping vessels in and around the Red Sea which could ultimately impact the availability of shipping routes and/or ocean freight, as well as increase the shipping costs, for raw material to our Yanbu pigment plant as well as TiO 2 exports out of our Yanbu plant. Specifically, KSA faces a number of
18

TABLE OF CONTENTS
challenges arising mainly from the relatively high levels of unemployment among the Saudi youth population, requests for political and social changes, and the security threat posed by certain groups. Should KSA experience similar political and social unrest as found in other countries in the Middle East, the Saudi Arabian economy could be adversely affected, our TiO 2 plant located in Yanbu could be temporarily disrupted or materially adversely affected and our business and operating results could be materially adversely affected.
Our results of operations may be adversely affected by fluctuations in currency exchange rates.
The financial condition and results of operations of our operating entities outside the U.S. are reported in various foreign currencies, primarily the South African Rand, Australian Dollars, Euros, Pound Sterling and Brazilian Real and then converted into U.S. dollars at the applicable exchange rate for inclusion in the financial statements. A significant portion of our costs are denominated in currencies other than the U.S. dollar. As a result, any volatility of the U.S. dollar against these foreign currencies creates uncertainty for, and may have a negative impact on, reported sales and operating margin. In addition, our operating entities often need to convert currencies they receive for their products into currencies in which they purchase raw materials or pay for services, which could result in a gain or loss depending on fluctuations in exchange rates. In order to manage this risk, we have from time to time, entered into forward contracts to buy and sell foreign currencies.
RISKS RELATING TO OUR DEBT AND CAPITAL STRUCTURE
We may need additional capital in the future and may not be able to obtain it on favorable terms or at all, including as a result of downgrades in our credit ratings, which may make it difficult for us to meet our financial commitments.
Our ability to obtain cash or other credit from external sources is impacted by many factors, including (i) debt covenants that limit our total borrowing capacity; (ii) the total amount of our outstanding secured and unsecured debt and the financial ratios and metrics thereof; (iii) increasing interest rates applicable to our floating rate debt; (iv) increasing demands from third parties for financial assurance or credit enhancement; (v) credit rating downgrades, which could limit our access to additional debt; (vi) a decrease in the market prices or value of our common stock and outstanding debt obligations; and (vii) volatility in public debt and equity markets.
Our substantial level of indebtedness increases the risk that we may be unable to generate cash sufficient to pay amounts due in respect of our indebtedness, and could limit our ability to obtain additional financing to fund future working capital, capital expenditures, or other general corporate requirements; require a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, and other general corporate purposes; and increase our vulnerability to general adverse economic and general industry conditions.
For example, our credit ratings may impact the cost and availability of future borrowings and, accordingly, our overall cost of capital. Our credit ratings reflect each rating organization’s opinion of our financial strength, operating performance, and ability to meet our debt obligations. The Company’s credit ratings were downgraded in 2025 by both Moody’s Ratings and S&P Global Ratings to “B2” and “CCC+,” respectively. Ratings by rating agencies may be changed or withdrawn at any time and no assurance can be given that we will not be subject to further downgrades. There is no guarantee that debt or equity financings will be available in the future to fund working capital, capital expenditures, or other general corporate purposes, or that such financing will be available on favorable terms or at all. See “Liquidity and Capital Resources” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 15 of notes to consolidated financial statements.
In addition, the market price of our debt obligations is based upon many factors, including expectations regarding the likelihood of future ability to effectuate repayment, the amount recoverable in the event of a default, our ability to pay interest and other ongoing debt service obligations, and the risk tolerance of each debt holder. If these or other factors cause the market price of our debt obligations to decrease, it may make it difficult or impossible for us to obtain additional capital in the future or meet our financial commitments.
Our capital expenditure projects may need additional capital in the future and may not realize expected investment returns.
Our business is capital intensive, and our success depends to a significant degree on our ability to maintain our manufacturing operations and invest in those operations to expand capacity and remain competitive from a cost perspective. We may require additional capital in the future to finance capital investments, for a variety of purposes, including (i) replacement of mines that are end of life, (ii) repair, maintenance, expansion, or optimization of existing production facilities or mining operations, (iii) ongoing research and development activities, (iv) business development opportunities in rare earth or other critical minerals, and (v) general working capital needs. For instance, we have substantially implemented the multi-year global business transformation that
19

TABLE OF CONTENTS
began in 2020 and includes the acquisition and implementation of new operational and financial systems, technology and processes, including a global ERP system, with additional work that will be necessary to complete projects in certain countries. Although we have taken, and will continue to take, significant steps to mitigate the potential negative impact of the implementation of such new digital systems, there can be no assurance that these procedures will be completely successful.
Additionally, if we undertake other capital expenditure projects, they may not be completed on schedule, at the budgeted cost, or at all. Moreover, our revenue may not increase immediately upon the expenditure of funds on a particular project. As a result, we may not be able to realize our expected investment return, which could adversely affect our results of operations and financial condition and ability to access additional sources of capital.
We are a holding company that is dependent on cash flows from our operating subsidiaries to fund our debt obligations, capital expenditures and ongoing operations.
All of our operations are conducted, and all of our assets are owned, by our operating companies, which are our subsidiaries. We intend to continue to conduct our operations at the operating company level. Consequently, our cash flows and our ability to meet our obligations or make cash distributions depends upon the cash flows of our operating companies, and the payment of funds by our operating companies in the form of dividends or otherwise. The ability of our operating companies to make any payments to us depends on their earnings, ability to generate cash, the terms of their indebtedness, including the terms of any credit facilities, or indentures, and legal restrictions regarding the transfer of funds.
Our ability to service our debt and fund our planned capital expenditures and ongoing operations will depend on our ability to generate and increase positive cash flows, and our access to additional liquidity sources. Our ability to generate and increase positive cash flows is dependent on many factors, including many of the other risks described in this section entitled “Risk Factors”.
The agreements and instruments governing our debt contain restrictions and limitations that could affect our ability to operate our business, as well as impact our liquidity.
As of December 31, 2025, our total principal amount of debt outstanding was approximately $3.2 billion. Our credit facilities and senior secured notes indenture contain covenants that could adversely affect our ability to operate our business, our liquidity, and our results of operations. These covenants may restrict, among other things, our and our subsidiaries' ability to:
•incur or guarantee additional indebtedness;
•complete asset sales, acquisitions or mergers;
•make investments and capital expenditures;
•prepay other indebtedness;
•enter into transactions with affiliates; and
•fund additional dividends or repurchase shares.
Certain of our credit facilities and notes indentures include requirements relating to the ratio of indebtedness or certain fixed charges to adjusted EBITDA. For instance, our Credit Agreement (as defined elsewhere herein) contains a springing financial covenant solely for the benefit of the revolving lenders of the Cash Flow Revolver (as defined elsewhere herein) under the Credit Agreement. The springing financial covenant requires compliance with a maximum first lien net leverage ratio of not greater than 4.75x (measuring the ratio of Consolidated First Lien Debt to Consolidated EBITDA, each as defined in the Credit Agreement) if, on the last day of any fiscal quarter, revolving exposure (excluding undrawn or cash collateralized letters of credit) exceeds 35% of the aggregate principal amount of all revolving commitments under the Cash Flow Revolver. In addition, the breach of any covenants or obligations in our credit facilities or notes indentures, not otherwise waived or amended, could result in a default under the applicable debt obligations (and potentially cross-defaults to certain other debt obligations) and could trigger acceleration of those obligations, which in turn could trigger other cross defaults under other existing or future agreements governing our long-term indebtedness. In addition, the secured lenders under the credit facilities and/or secured noteholders under our secured indenture could foreclose on their collateral, which includes substantially all our assets (including, among other things, inventory, receivables and related assets, and equipment, equity interests in subsidiaries and material real property, in each case subject to certain limitations and exceptions), and exercise other rights generally available to secured creditors. Any default under those credit facilities and/or secured indenture, could adversely affect our growth, our financial condition, our results of operations and our ability to make payments on our credit facilities, notes, and other financial obligations, and could force us to seek the protection of bankruptcy laws.
RISKS RELATING TO OUR LEGAL AND REGULATORY ENVIRONMENT
20

TABLE OF CONTENTS
Our South African mining rights are subject to onerous regulatory requirements imposed by legislation and the Department of Mineral Resources and Energy, the compliance with which could have a material adverse effect on our business, financial condition and results of operations.
Black economic empowerment (BEE) legislation was introduced in South Africa to address inequalities from the Apartheid system by including historically disadvantaged South Africans in the mainstream economy. BEE legislation requires certain operations to be partially owned by historically disadvantaged South Africans and comply with provisions related to procurement and employment opportunities. On March 1, 2019, Mining Charter III came into effect requiring a 30% BEE shareholding structured through a special purpose vehicle as well as setting forth stringent requirements for procurement, employment quotas, and workers' living conditions. In September 2021, the South African High Court ruled certain provisions of Mining Charter III unconstitutional, creating uncertainty about its status. Prior to Mining Charter III, Mining Charter II governed BEE in the mining sector, with a 26% ownership obligation. Our two South African operating subsidiaries are considered "once empowered always empowered" meaning that those companies with the requisite shareholding base as of December 31, 2014, will always qualify as "empowered" for retaining existing mining rights. This principle was confirmed by the South African High Court and applies to the renewal and transfer of mining rights. However, there is no assurance that any new legislation won't undermine this ruling, potentially having a material adverse effect on the South African companies ownership regime, requiring re-empowerment which will impact our business, financial condition and results of operations. However, there is no assurance that new legislation will not be enacted that would undermine the court's ruling regarding the applicability of "once empowered always empowered" to the renewal and transfer of mining rights. In the event that "once empowered always empowered" does not ultimately apply to the renewal or transfer of mining rights it could have a material adverse effect on our business, financial condition and results of operations.
Our failure to comply with the anti-corruption laws of the U.S. and various international jurisdictions could negatively impact our reputation and results of operations.
Doing business on a global basis requires us to comply with the laws and regulations of the U.S. government and those of various international jurisdictions, and our failure to successfully comply with these rules and regulations may expose us to liabilities. In particular, our operations are subject to U.S. and foreign anti-corruption laws and regulations, such as the U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act 2010 (“U.K. Bribery Act”), as well as anti-corruption laws of the various jurisdictions in which we operate. Our global operations may expose us to the risk of violating, or being accused of violating, the foregoing or other anti-corruption laws. Such violations could be punishable by criminal fines, imprisonment, civil penalties, disgorgement of profits, injunctions, and exclusion from government contracts, as well as other remedial measures. Investigations of alleged violations can be very expensive, disruptive, and damaging to our reputation. Although we have implemented anti-corruption policies and procedures, there can be no guarantee that these policies, procedures, and training will effectively prevent violations by our employees or representatives in the future. Additionally, we face a risk that our distributors and other business partners may violate the FCPA, the U.K. Bribery Act, or similar laws or regulations. Such violations could expose us to FCPA and U.K. Bribery Act liability and/or our reputation may potentially be harmed by their violations and resulting sanctions and fines.
We are subject to many environmental, health and safety regulations.
Our operations and production facilities are subject to extensive environmental and health and safety laws and regulations at national, international and local levels in numerous jurisdictions relating to use of natural resources, pollution, protection of the environment, mine site remediation, transporting and storing raw materials and finished products, and storing and disposing of hazardous wastes among other materials. Moreover, certain environmental laws impose joint and several and/or strict liability for costs to clean up and restore sites where pollutants have been disposed or otherwise spilled or released. We cannot be certain that we will not incur significant costs and liabilities for remediation or damage to property, natural resources or persons as a result of spills or releases from our operations or those of a third party.
The costs of compliance with the extensive environmental, health and safety laws and regulations or the inability to obtain, update or renew permits required for operation or expansion of our business could negatively impact our results of operations or otherwise adversely affect our business. If we fail to comply with the conditions of our permits governing the production and management of regulated materials, mineral sands mining licenses or leases or the provisions of the relevant jurisdictional laws in which we operate, these permits, mining licenses or leases and mining rights could be canceled or suspended, and we could be prevented from obtaining new mining and prospecting rights, which could materially and adversely affect our business, operating results and financial condition. Additionally, we could incur substantial costs, including fines, damages, criminal or civil sanctions and remediation costs, or experience interruptions in our operations, for violations arising under these laws and regulations, including operating without the required permits, mining licenses or leases and/or mining rights. In the event of a catastrophic incident involving any of the raw materials we use, or chemicals or mineral products we produce, we could incur material costs as a result of addressing the consequences of such event.

TABLE OF CONTENTS
Changes to existing laws governing operations, especially changes in laws relating to transportation of mineral resources, the treatment of land and infrastructure, contaminated land, the remediation of mines, tax royalties, waste handling and management, exchange control restrictions, environmental remediation, mineral rights, ownership of mining assets, or the rights to prospect and mine may have a material adverse effect on our future business operations and financial performance. There is risk that onerous conditions may be attached to authorizations in the form of mining rights, water-use licenses, miscellaneous licenses and environmental approvals, or that the grant of these approvals may be delayed or not granted.
Our TiO 2 products are subject to increased regulatory scrutiny, that may impede or inhibit widespread usage of TiO 2 and / or diminish the Company’s ability to sustain or grow its business or may add significant costs of doing business.
Current regulatory and societal demands for increased protection against products which may cause cancer, genetic mutations or other long-term health problems are resulting in increased pressure for more stringent regulation of our TiO 2 products. We expect these trends to continue and the ultimate cost of compliance could be material. In particular, changes to product safety regulations could limit the use of, and demand for, our TiO 2 products, require investment in new product development or the way we manufacture our existing products, and increase regulatory compliance expenditures for us and our suppliers.
For instance, the Health and Safety Executive in the U.K. has published the U.K.’s mandatory classification and labelling list, which includes the classification of TiO 2 as a suspected carcinogen (in a powder form containing 1% or more of particles with aerodynamic diameter ≤ 10 μm). The classification became mandatory in the U.K. in October 2021.
In May 2021, the European Food Safety Authority (EFSA) announced new guidelines which concluded that a certain digestible form of TiO 2 known as E171 is no longer considered safe as a food additive due to uncertainty for genotoxicity. Though we do not manufacture E171, the EFSA guidelines indicate additional regulatory review of our TiO 2 products is likely which could result in more stringent qualifications and use-restriction being applied or to the introduction of further classifications. It is also possible that heightened regulatory scrutiny could lead to claims by consumers or those involved in the production of such products alleging adverse health impacts. Any adverse outcomes with respect to regulatory investigations into the ongoing use of TiO 2 in various sectors could have a material adverse effect on our business, financial condition and results of operations. In addition, there is no assurance that other materials which we add to our TiO 2 products could be subject to increased regulations which could negatively impact our business.
Sustainability issues as they may be applicable to certain jurisdictions, including those related to climate change, may subject us to additional costs and restrictions, including increased energy and raw material costs, which could have an adverse effect on our business, financial condition and results of operations, as well as damage our reputation.
Climate change resulting from increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere could present risks to our present and future operations from natural disasters and extreme weather conditions, such as flooding, hurricanes, earthquakes and wildfires. Such extreme weather conditions could pose physical risks to our facilities and disrupt the operation of our supply chain, increase operational costs and have a material adverse effect on our business and results of operations. In addition, if any of the equipment on which we depend were severely damaged or were destroyed by environmental hazards or otherwise, we may be unable to replace or repair it in a timely manner or at a reasonable cost, which would impact our ability to produce and ship our products, which would have a material adverse effect on our business, financial condition or results of operations. For instance, in the fourth quarter of 2022, the region of New South Wales, Australia where our Eastern Operations mining operations are located experienced historic flooding which resulted in, among other things, a delay in the commissioning of our Atlas mine as well as prevented feedstock mined at such site from being transported to our Australian pigment plants in a timely manner. Such flooding had an adverse effect on our business, financial condition and results of operations in 2022 and 2023. Moreover, the impacts of climate change on global water resources may result in water scarcity, which could impact our ability to access sufficient quantities of water in certain locations and result in increased costs. For instance, we use significant amounts of water in our South Africa operations. Certain regions of South Africa have experienced in the past, and are prone to, drought conditions resulting in water restrictions being imposed in such areas. A prolonged drought in a region of South Africa where our operations are located may lead to water use restrictions which could have a material adverse effect on our business, financial condition and results of operations.
The majority of our greenhouse gas emissions are generated from our TiO 2 slag furnaces in South Africa, synthetic rutile kiln in Australia, and TiO 2 pigment plants in the United States, United Kingdom, France, Brazil, Australia, and Saudi Arabia. Concerns about the relationship between greenhouse gases and global climate change, and an increased focus on carbon neutrality, may result in new or increased legal and regulatory requirements on both national and supranational levels, to monitor, regulate, control and tax emissions of carbon dioxide and other greenhouse gases. A number of governmental bodies have already introduced, or are contemplating, regulatory changes in response to climate change, including regulating greenhouse gas emissions. Any laws or regulations that are adopted to reduce emissions of greenhouse gases could, among other things, (i) cause
22

TABLE OF CONTENTS
an increase to our raw material costs, (ii) increase our costs to operate and maintain our facilities including potentially causing the operation or maintenance of certain sites to be uneconomical, and (iii) increase costs to administer and manage emissions programs.
In addition, companies across all industries are facing increasing scrutiny relating to their sustainability policies. Increased focus and activism related to sustainability may hinder the Company’s access to capital, as investors may reconsider their capital investment as a result of their assessment of the Company’s sustainability practices. In particular, customers, investors and other stakeholders are increasingly focusing on environmental issues, including climate change, water use, and other sustainability concerns. Moreover, increased regulatory requirements, including in relation to various aspects of sustainability including disclosure requirements, may result in increased compliance or input costs of energy, raw materials or compliance with emissions standards, which may cause disruptions in the manufacture of our products or an increase in operating costs. Any failure to achieve our sustainability goals or a perception of our failure to act responsibly with respect to the environment or to effectively respond to new, or changes in, legal or regulatory requirements concerning environmental or other sustainability matters, or increased operating or manufacturing costs due to increased regulation, could adversely affect our business, financial condition and results of operations, as well as our reputation.
If our intellectual property were compromised or copied by competitors, or if competitors were to develop similar intellectual property independently, our results of operations could be negatively affected. Further, third parties may claim that we infringe on their intellectual property rights which could result in costly litigation.
Our success depends to a significant degree upon our ability to protect and preserve our patents and unpatented proprietary technology, operational knowledge and other trade secrets (collectively "intellectual property rights"). The undetected or unremedied unauthorized use of our intellectual property rights or the legitimate development or acquisition of intellectual property related to our industry by third parties could reduce or eliminate any competitive advantage we have as a result of our intellectual property rights. If we must take legal action to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of our resources and our management’s attention, and we may not prevail in any such suits or proceedings. A failure to protect, defend or enforce our intellectual property rights could have an adverse effect on our financial condition and results of operations.
Although there are currently no pending or threatened proceedings or claims known to us that are material relating to alleged infringement, misappropriation or violation of the intellectual property rights of others, we may be subject to legal proceedings and claims in the future in which third parties allege that their patents or other intellectual property rights are infringed, misappropriated or otherwise violated by us or our products or processes. In the event that any such infringement, misappropriation or violation of the intellectual property rights of others is found, we may need to obtain licenses from those parties or substantially re-engineer our products or processes to avoid such infringement, misappropriation or violation. We might not be able to obtain the necessary licenses on acceptable terms or be able to re-engineer our products or processes successfully. Moreover, if we are found by a court of law to infringe, misappropriate or otherwise violate the intellectual property rights of others, we could be required to pay substantial damages or be enjoined from making, using or selling the infringing products or technology. We also could be enjoined from making, using or selling the allegedly infringing products or technology pending the final outcome of the suit. Any of the foregoing could adversely affect our financial condition and results of operations.
We may be subject to litigation, the disposition of which could have a material adverse effect on our results of operations.
The nature of our operations and status as a public company exposes us to possible litigation claims, including disputes with competitors, customers, shareholders (including purported class actions), equipment vendors, environmental groups and other non-governmental organizations, providers of shipping services as well as governmental agencies. Some of the lawsuits may seek fines or penalties and damages in large or indeterminable amounts, or seek to restrict our business activities. Because of the uncertain nature of any litigation and coverage decisions, we cannot predict the outcome of these matters or whether insurance claims may mitigate any damages to us. Litigation is very costly, and the costs associated with prosecuting and defending litigation matters could have a material adverse effect on our results of operations and financial condition. See Note 20 of notes to our consolidated financial statements, included elsewhere in this Form 10-K for further information regarding our commitments and contingencies.
We may be subject to claims that arise from activities prior to our emergence from bankruptcy in 2011.
On November 30, 2010, the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) confirmed our plan of reorganization (the “Plan”), which became effective in February 2011. The Plan included a discharge and release of any and all claims based on liabilities arising prior to emergence from the bankruptcy. Nonetheless, from time to time, we have received and in the future may receive inquiries or notices of potential or asserted claims arising under certain environmental laws or regulations with respect to properties our predecessor companies, or companies they acquired, may have
23

TABLE OF CONTENTS
owned or operated before our emergence from bankruptcy. We believe that the Plan confirmed by the Bankruptcy Court extinguished all such claims, and intend to vigorously defend against such claim. However, there can be no assurance that we will be successful in defending against such claims and any adverse outcomes with respect to such claims could have a material adverse effect on our business, financial condition and results of operations.
Our flexibility in managing our labor force may be adversely affected by labor and employment laws in the jurisdictions in which we operate, many of which are more onerous than those of the U.S.; and some of our labor force has substantial workers' council or trade union participation, which creates a risk of disruption from labor disputes and new laws affecting employment policies.
The vast majority of our employees are located outside the U.S. In most of those countries, labor and employment laws are more onerous than in the U.S. and, in many cases, grant significant job protection to employees, including rights on termination of employment. Moreover, many of our workforce outside the U.S. belong to unions and/or are represented by a collective bargaining agreement. As such, in such jurisdictions we are required to consult with, and seek the consent or advice of, various employee groups or works’ councils that represent our employees for any changes to our activities or employee benefits. This requirement could have a significant impact on our flexibility in managing costs and responding to market changes.
RISKS RELATING TO ACCOUNTING AND TAXATION
If our intangible assets or other long-lived assets become impaired, we may be required to record a significant noncash charge to earnings.
We have a significant amount of intangible assets and other long-lived assets on our consolidated balance sheets. Under U.S. GAAP, we review our intangible assets and other long-lived assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Factors that may be considered a change in circumstances, indicating that the carrying value of our intangible assets and other long-lived assets may not be recoverable, include, but are not limited to, a significant decline in share price and market capitalization, changes in the industries in which we operate, particularly the impact of a downturn in the global economy, as well as competition or other factors leading to reduction in expected long-term sales or results of operations. We may be required to record a significant noncash charge in our financial statements during the period in which any impairment of our intangible assets and other long-lived assets is determined, negatively impacting our results of operations.
Our ability to use our tax attributes to offset future income may be limited.
Our ability to use net operating losses (“NOLs”) and Section 163(j) interest expense carryforwards generated by us could be substantially limited if we were to experience an “ownership change” as defined under Section 382 of the U.S. Internal Revenue Code of 1986, as amended ("the Code"). In general, an ownership change would occur if our “5-percent shareholders,” as defined under Section 382 of the Code and including certain groups of persons treated as “5-percent shareholders,” collectively increased their ownership in us by more than 50 percentage points over a rolling three-year period. Although we believe we have sufficient protection of our approximately $4.3 billion of NOLs and/or approximately $370 million of Section 163(j) interest expense carryforwards, there can be no assurance that an ownership change for U.S. federal and applicable state income tax purposes will not occur in the future. A corporation that experiences an ownership change will generally be subject to an annual limitation on the use of certain pre-ownership change losses and/or credits. Such a limitation could, for any given year, have the effect of increasing the amount of our U.S. federal and/or state income tax liability, which would negatively impact our financial condition and the amount of after-tax cash available for distribution to holders of our ordinary shares if declared by our board of directors.
We could be subject to changes in tax rates, adoption of new tax laws or additional tax liabilities.
We are subject to taxation in all of the jurisdictions in which we operate. Our future effective tax rate could be affected by, among other things, changes in statutory rates and other legislative changes, or changes in determinations regarding the jurisdictions in which we are subject to tax or changes in the valuation of our deferred tax assets and liabilities. From time to time, the U.S. federal, state and local and foreign governments make substantive changes to tax rules and their application, which could result in higher corporate taxes than would be incurred under existing tax law and could have an adverse effect on our results of operations or financial condition. From time to time, we are also subject to tax audits by various taxing authorities. For instance, we are currently under audit by the Australian Taxation Office for the calendar years 2017 - 2022. Although we believe our tax positions are appropriate, the final determination of any future tax audits could be materially different from our income tax provisions, accruals and reserves and any such unfavorable outcome from a future tax audit could have a material adverse effect on our results of operations or financial condition.

TABLE OF CONTENTS
Failure to meet some or all of our key financial and non-financial targets could negatively impact the value of our business and adversely affect our stock price.
From time to time, we may announce certain key financial and non-financial targets that are expected to serve as benchmarks for our performance for a given time period, such as, projections for our future revenue growth, Adjusted EBITDA, Adjusted diluted earnings per share and free cash flow. Our failure to meet one or more of these key financial targets may negatively impact our results of operations, stock price, shareholder returns and the prices of our debt securities. The factors influencing our ability to meet these key financial targets include, but are not limited to, changes in the global economic environment relating to our TiO 2 products and zircon, changes in our competitive landscape, including our relationships with new or existing customers, our ability to introduce new products, applications, or technologies, our inability to complete strategic projects on budget or on schedule, our undertaking an acquisition, joint venture, or other strategic arrangement, and other factors described within this Item 1A – Risk Factors, many of which are beyond our control.
RISKS RELATING TO INVESTING IN OUR ORDINARY SHARES
Concentrated ownership of our ordinary shares by Cristal may prevent minority shareholders from influencing significant corporate decisions and may result in conflicts of interest.
As of December 31, 2025, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), an affiliate of the National Titanium Dioxide Company Limited ("Cristal"), owned approximately 24% of our outstanding ordinary shares. As such, Cristal International may be able to influence fundamental corporate matters and transactions. This concentration of ownership, may delay, deter or prevent acts that would be favored by our other shareholders. The interests of Cristal International may not always coincide with our interests or the interests of our other shareholders. Also, Cristal International may seek to cause us to take courses of action that, in their judgment, could enhance their investment in us, but which might involve risks to our other shareholders or adversely affect us or our other shareholders.
In addition, under the shareholders agreement (the “Cristal Shareholders Agreement”) we entered into at the closing of the Cristal transaction with Cristal, as long as Cristal International and the three shareholders of Cristal (collectively, the “Cristal Shareholders”) collectively beneficially own at least 24,900,000 or more of our ordinary shares, they have the right to designate for nomination two directors of our board of directors (the “Board”). As long as the Cristal Shareholders collectively beneficially own at least 12,450,000 ordinary shares but less than 24,900,000 ordinary shares, they have the right to designate for nomination one director of the Board. The Cristal Shareholders Agreement also provides that as long as the Cristal Shareholders collectively beneficially own at least 12,450,000 ordinary shares they have certain preemptive rights. Also, pursuant to the Cristal Shareholders Agreement, Cristal has certain registration rights requiring the Company to register with the SEC shares that are owned and may be resold by Cristal.
As a result of these or other factors, including as a result of any offering of shares by Cristal, or the perception that such sales may occur, the market price of our ordinary shares could decline. In addition, this concentration of share ownership may adversely affect the trading price of our ordinary shares because investors may perceive disadvantages in owning shares in a company with significant shareholders or with significant outstanding shares with registration rights.
English law and provisions in our articles of association may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our shareholders, and may prevent attempts by our shareholders to replace or remove our current management.
Certain provisions of the U.K. Companies Act 2006 (the “Companies Act”) and our articles of association may have the effect of delaying or preventing a change in control of us or changes in our management. For example, our articles of association include provisions that:
•maintain an advance notice procedure for proposed nominations of persons for election to our board of directors;
•provide certain mandatory offer provisions, including, among other provisions, that a shareholder, together with persons acting in concert, that acquires 30 percent or more of our issued shares without making an offer to all of our other shareholders that is in cash or accompanied by a cash alternative would be at risk of certain sanctions from our board of directors unless they acted with the prior consent of our board of directors or the prior approval of the shareholders; and
•provide that vacancies on our board of directors may be filled by a vote of the directors or by an ordinary resolution of the shareholders.
25

TABLE OF CONTENTS
In addition, public limited companies are prohibited under the Companies Act from taking shareholder action by written resolution. These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management.
Although we do not anticipate being subject to the U.K. City Code on Takeovers and Mergers, such Takeover Code may still have anti-takeover effects in the event the Takeover Panel determines that such Code is applicable to us.
The U.K. City Code on Takeovers and Mergers (the “Takeover Code”) applies, among other things, to an offer for a public company whose registered office is in the U.K. (or the Channel Islands or the Isle of Man) and whose securities are not admitted to trading on a regulated market in the U.K. (or on any stock exchange in the Channel Islands or the Isle of Man) if the company is considered by the Panel on Takeovers and Mergers (the “Takeover Panel”) to have its place of central management and control in the U.K. (or the Channel Islands or the Isle of Man). This is known as the “residency test.” The test for central management and control under the Takeover Code is different from that used by the U.K. tax authorities. Under the Takeover Code, the Takeover Panel will determine whether we have our place of central management and control in the U.K. by looking at various factors, including the structure of our board of directors, the functions of the directors and where they are resident.
Given that currently all of the members of our Board of Directors reside outside the United Kingdom, we do not anticipate that we will be subject to the Takeover Code. However, if at the time of a takeover offer, the Takeover Panel determines that we have our place of central management and control in the U.K., we would be subject to a number of rules and restrictions, including but not limited to the following: (1) our ability to enter into deal protection arrangements with a bidder would be extremely limited; (2) we might not, without the approval of our shareholders, be able to perform certain actions that could have the effect of frustrating an offer, such as issuing shares or carrying out acquisitions or disposals; and (3) we would be obliged to provide equality of information to all bona fide competing bidders.
As a public limited company incorporated in England and Wales, certain capital structure decisions requires approval of our shareholders, which may limit our flexibility to manage our capital structure.
The Companies Act generally provides that a board of directors of a public limited company may only allot shares (or grant rights to subscribe for or convertible into shares) with the prior authorization of shareholders, such authorization stating the maximum amount of shares that may be allotted under such authorization and specifying the date on which such authorization will expire, being not more than five years, each as specified in the articles of association or relevant shareholder resolution. We obtained previous shareholder authority to allot additional shares for a period from May 7, 2025 through the end of the Company's 2026 annual general meeting of shareholder, or if earlier, the close of business on the date that is fifteen (15) months after May 7, 2025.
The Companies Act generally provides that existing shareholders of a company have statutory pre-emption rights when new shares in such company are allotted and issued for cash. However, it is possible for such statutory pre-emption right to be disapplied by either shareholders passing a special resolution at a general meeting, being a resolution passed by at least 75% of the votes cast, or by inclusion of relevant provisions in the articles of association of the company. Such a disapplication of statutory pre-emption rights may not be for more than five years. We obtained previous shareholder authority to disapply statutory pre-emption rights for a period from May 7, 2025 through the end of the Company's 2026 annual general meeting of shareholder, or if earlier, the close of business on the date that is fifteen (15) months of May 7, 2025.
The Companies Act generally prohibits a public limited company from repurchasing its own shares without the prior approval of its shareholders by ordinary resolution, being a resolution passed by a simple majority of votes cast, and subject to compliance with other statutory formalities. Such authorization may not be for more than five years from the date on which such ordinary resolution is passed. We obtained previous shareholder authority to repurchase shares for a period from May 7, 2025 through the end of the Company's 2026 annual general meeting of shareholder, of if earlier, the close of business on the date that is fifteen (15) months after May 7, 2025.
Transfers of our ordinary shares outside The Depository Trust may be subject to stamp duty or stamp duty reserve tax in the U.K., which would increase the cost of dealing in our shares.
Except for ordinary shares received by a holder deemed to be an affiliate of us for purposes of U.S. securities laws, our ordinary shares have been issued to a nominee for The Depository Trust Company (“DTC”) and corresponding book-entry interests credited in the facilities of DTC. On the basis of current law and HM Revenue and Customs (“HMRC”) practice, no charges to U.K. stamp duty or stamp duty reserve tax (“SDRT”) are expected to arise on the issue of the ordinary shares into DTC’s facilities or on transfers of book-entry interests in ordinary shares within DTC’s facilities.
26

TABLE OF CONTENTS
Shareholders are strongly encouraged to hold their ordinary shares in book entry form through DTC. Transfers of shares held in book entry form through DTC currently do not attract a charge to stamp duty or SDRT in the U.K. A transfer of title in the shares from within the DTC system out of DTC, including to certificate shares, and any subsequent transfers that occur entirely outside the DTC system will attract a charge to stamp duty at a rate of 0.5% of any consideration, which is payable by the transferee of the shares. Any such duty must be paid (and the relevant transfer document, if any, stamped by HMRC) before the transfer can be registered in our books. However, if those shares are redeposited into DTC, the redeposit will attract stamp duty or SDRT at the rate of 1.5% to be paid by the transferor.
We have put arrangements in place such that directly held ordinary shares cannot be transferred into the DTC system until the transferor of the ordinary shares has first delivered the ordinary shares to a depositary specified by us so that SDRT may be collected in connection with the initial delivery to the depositary. Any such ordinary shares will be evidenced by a receipt issued by the depositary. Before the transfer can be registered in our books, the transferor will also be required to put the depositary in funds to settle the resultant liability to SDRT, which will be charged at a rate of 1.5% of the value of the shares.
Our articles of association provide that the courts of England and Wales have exclusive jurisdiction to determine any dispute brought by a shareholder in that shareholder's capacity as such and certain other matters.
Our articles of association provide that the courts of England and Wales have exclusive jurisdiction to determine any dispute brought by a shareholder in that shareholder's capacity as such, or related to or connected with any derivative claim in respect of a cause of action vested in us or seeking relief on our behalf, against us and/or the board and/or any of the directors, former directors, officers, employees or shareholders individually, arising out of or in connection with our articles of association or (to the maximum extent permitted by applicable law) otherwise. This choice of forum provision may limit a shareholder's ability to bring a claim in a judicial forum that the shareholder believes is favorable for disputes with us or our directors, former directors, officers, employees or shareholders which may discourage lawsuits against us and our directors, former directors, officers, employees or shareholders.
There may be difficulty in effecting service of legal process and enforcing judgments against us and our directors and management.
We are incorporated under the laws of England and Wales and a substantial portion of our assets are located outside of the U.S. The U.S. and the U.K. do not currently have a treaty providing for the recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. The enforceability of any judgment of a U.S. federal or state court in the U.K. will depend on the laws and any treaties in effect at the time, including conflicts of laws principles (such as those bearing on the question of whether a U.K. court would recognize the basis on which a U.S. court had purported to exercise jurisdiction over a defendant). In this context, there is doubt as to the enforceability in the U.K. of civil liabilities based solely on the federal securities laws of the U.S. In addition, awards for punitive damages in actions brought in the U.S. or elsewhere may be unenforceable in the U.K.. An award for monetary damages under U.S. securities laws would likely be considered punitive if it did not seek to compensate the claimant for loss or damage suffered and was intended to punish the defendant.

Item 1C. Cybersecurity
Risk Management and Strategy
As part of our overall risk management system we maintain comprehensive policies and processes for assessing, identifying and managing material risks from cybersecurity threats, including risks relating to production, safety, reputation, intellectual property, procurement and business continuity. Cybersecurity risk management is included as part of our overall annual Enterprise Risk Management program. As part of this program, our enterprise risk professionals consult with internal cybersecurity subject matter experts to identify cyber risks and evaluate their severity and the efficacy of our mitigation efforts, with the results being reported to the executive leadership team and the Board of Directors.
Our cybersecurity risk management processes and policies include the following:
•We seek to deploy best practice cybersecurity standards promulgated by the National Institute of Standards and Technology Cybersecurity (NIST), the International Organization for Standardization and the Center for Internet Security.
27

TABLE OF CONTENTS
•We employ a dedicated cybersecurity team who routinely conduct specific risk assessments and endeavor to mitigate identified risks. This team is responsible for implementing measures to detect, prevent and respond to threats and malicious activity. We also maintain a Security Operations Center (SOC) that provides a mechanism for addressing cyberthreats before they comprise data security.
•The cybersecurity team operates, maintains and monitors an integrated eco-system of security tools designed to detect, prevent and respond to threats and malicious activity. These tools include, but are not limited to, firewalls, anti-malware, IPS / IDS, end point protection, encryption, email and cloud app security, privileged access management, vulnerability scanning / patching. These are a blend of on-premise, cloud and network hosted tools. Monitoring activities include threat hunting and use of multiple intelligence sources to manage and respond to events.
•Access to information is subject to authorization, review, classification and substantially controlled through multi-factor authentication.
•All employees and contractors who are issued a Tronox user account for our IT system must complete and pass cybersecurity training before being provided full system access.
•All employees and contractors with access to our IT systems must complete and pass a mandatory annual cybersecurity awareness training and acknowledgement of Tronox’s Acceptable Use Policy. Failure to complete the training successfully may result in further system access restrictions and HR escalation.
•We periodically orchestrate simulated phishing attacks on all IT system users and those who fall victim to the simulated attacks are required to take additional mandatory cybersecurity training.
•To reduce the risk of phishing attacks, we have identified groups of Tronox employees and contractors who do not require access to external emails in order to perform their work responsibilities and begun a process of blocking their external emails.
•We have a written Incident Response Plan that encompasses a range of activities to detect, respond to and recover from cybersecurity incidents, including compliance with applicable legal obligations and mitigation damage.
•We work closely with a number of regional and international bodies from which we draw intelligence and contribute to cybersecurity initiatives such as incident simulation exercises and development working groups.
•We regularly evaluate the appropriateness of cyber insurance coverage in light of the cyber risks we face and we do not currently carry cyber insurance.
Additionally, in connection with our cybersecurity risk management processes, we engage third-party subject matter experts to supplement our dedicated internal resources and to provide independent review of the Tronox-specific threat landscape as well as our mitigation efforts to counter known threats. These activities include:
•External penetration testing by certified third parties.
•Independent review of the Tronox Information Security Management System (ISMS).
•Participating in industry and government cyber incident exercises run by the National Cyber Security Center (UK Security Services).
•Utilizing a third party (KnowBe4) for the cybersecurity training and phishing tests described above.
•Regularly engaging with statutory auditors in support of specific activities such as SOX 404 audits.
•Engaging outside counsel with expertise in the field to advise on critical IT contracts as well as reporting and disclosure requirements.
•Membership in a United Kingdom industry cybersecurity group to facilitate intelligence sharing and develop incident response capabilities.
•Utilizing a third party vendor for detect and response services who provides 24x7 monitoring and incident response capabilities across the various Tronox technology platforms.
Our cybersecurity risk management policies and processes extend to cyber risks posed by our third-party service providers. To manage that risk we have implemented a process to identify critical vendors and perform a reasonable level of due diligence on the adequacy of their cybersecurity policies, processes and capabilities.
Our business strategy, results of operations and financial condition have not been materially affected by risks from cybersecurity threats, including as a result of previous cybersecurity incidents, but we cannot provide assurance that they will not be materially affected in the future by such risks and any future material incidents. Like most major corporations we have been the target of cyberattacks from time to time and we expect to be the target of such attacks in the future. In the past three years, however, we have not experienced a material information security breach. As such, we have not incurred any material expenses from cybersecurity breaches or any expenses from fines, penalties or settlements related to a cybersecurity breach. See “Risk Factors” in Item 1A of this Annual Report on Form 10-K for more information on risks from cybersecurity threats that are reasonably likely to materially affect our business strategy, results of operations and financial condition.
Governance
28

TABLE OF CONTENTS
Our entire Board of Directors provides oversight of the Company’s cybersecurity policies, processes and capabilities as part of their overall oversight of risk management. Once a year, our Vice President, Global Digital Operations and Security reports to the Audit Committee providing a detailed update on the threat landscape, emerging trends and the Company’s mitigation efforts. As needed on a periodic basis, our Vice President, Global Digital Operations and Security updates the Audit Committee on specific cybersecurity events and newly emerging risks and the actions taken by the Company in response to those events and risks. The Audit Committee updates the full board on these matters as necessary. The full Board reviews and assesses cybersecurity risks in connection with its annual Enterprise Risk Management review.
In 2020, Tronox established an IT Security Council to help set corporate risk tolerance and related policy. The council meets quarterly, is chaired by the General Counsel and managed by our Vice President, Global Digital Operations and Security with senior level representation from key functions and business units. On an annual basis, the Tronox Cybersecurity team reviews and updates the core governance documents, including the Acceptable Use Policy, the Information Security Policy, and the Incident Response Plan. These are then subject to review and approval by the Tronox Security Council with a summary provided to the Audit Committee as a component of the annual cybersecurity Enterprise Risk Management.
Day to day cybersecurity risk oversight governance is the responsibility of our Vice President, Global Digital Operations and Security who has been with Tronox since 2021 and reports to our Senior Vice President, Integrated Supply Chain and Digital Transformation. Tronox’s Vice President, Global Digital Operations and Security has over 30 years of IT experience, across technology engineering, operations and security. Previous roles include leadership roles ranging from Interim Chief Information Officer, Vice President of Engineering, Operations and Security Operations and Vice President of Operations. He oversees a dedicated security team distributed globally with more than seven members and a dedicated security operations center.

Overview of Our Vertical Integration
Tronox is the world's leading vertically integrated manufacturer of TiO 2 pigment. We produce the majority of our internal TiO 2 pigment feedstock requirements internally at our mine and mineral processing facilities. Our supply chain consists of mining operations in South Africa and Australia, separation and upgrading facilities located near our mines where we separate and process raw ore and then “upgrade” the titanium content of the raw ore to produce specialized chloride TiO 2 feedstock materials (titanium slag and synthetic rutile) and seven TiO 2 pigment production facilities located on six continents. The internal TiO 2 feedstocks we produce include titanium slag, synthetic rutile, natural rutile, leucoxene, chloride ilmenite and sulfate ilmenite.
As part of our TiO 2 value chain, we explore, acquire, mine and process heavy mineral sands to produce Heavy Mineral Concentrate (“HMC”) from which the Valuable Heavy Mineral (VHM) titanium and zircon products are made. HMC is produced from heavy mineral sands primarily through spiral gravity concentration at our mines. Mined material is transported to our nearby integrated mineral separation plants (MSP) to separate and concentrate VHMs by gravity, magnetic and electrostatic techniques. Multiple grades of titanium minerals and zircon may be produced from each MSP. The three titanium feedstocks which result from the MSP process (natural rutile, leucoxene and ilmenite) are each handled differently. Natural rutile and leucoxene are ordinarily shipped from the MSP to one of our TiO 2 pigment production facilities. Depending on the TiO 2 content of mined ilmenite, we either use it directly to produce TiO 2 pigment or we upgrade it to produce titanium slag at our two South African smelter operations and synthetic rutile (SR) at our Chandala metallurgical complex in Western Australia. Our internally sourced titanium mineral products provide a secure, long-term low-cost supply of high-grade feedstock for our TiO 2 pigment manufacturing facilities.
There is a high degree of substitutability among natural rutile, synthetic rutile, titanium slag, leucoxene and chloride ilmenite as titanium feedstocks for chloride pigment production. The commercial value of titanium feedstock is a function not only of TiO 2 content and supply and demand balances, but also particle size, trace element geochemistry, logistics and other factors. The global TiO 2 industry is a value-added supply chain, with final product prices for TiO 2 pigment, typically significantly higher than that of chloride or sulfate ilmenite, the backbone of the global titanium mineral supply. The revenue assumptions for titanium feedstocks
29

TABLE OF CONTENTS
we applied to determine our reserve estimates, as described below, are based on market intelligence gathered from internal and external experts, sales contracts and historic pricing. The economic assessment is done on a minerals only basis and no value of downstream upgrading is attributed to the minerals units.
In 2025, we produced concentrates of ilmenite, rutile, leucoxene, and zircon from five operations:
–Namakwa Sands, Western Cape, South Africa;
–KwaZulu-Natal (“KZN”) Sands, KwaZulu-Natal, South Africa;
–Northern Operations, Western Australia;
–Southern Operations, Western Australia; and
–Eastern Operations, Murray Basin, New South Wales, Australia.
Ilmenite from our Namakwa and KZN Sands mines in South Africa is converted to titanium slag at our smelters at Saldanha Bay, Western Cape and Empangeni, KwaZulu-Natal, respectively. Ilmenite from our Cooljarloo mine in Western Australia is converted to SR at our Chandala metallurgical complex which is most commonly used as feedstock to our TiO 2 pigment plants at Kwinana and Kemerton, both of which are south of Perth in Western Australia.
Mining Operations
Tronox owns and operates five mining and mineral processing operations, each including one or more heavy mineral sand (“HMS”) mines producing HMC which is separated into valuable co-products, primarily zircon and TiO 2 feedstocks --- ilmenite, natural rutile or leucoxene --- in a dedicated mineral separation plant.
In South Africa, the Namakwa Sands operations include two open-pit mines at Brand-se-Baai, each with a dedicated primary gravity concentration plant and a secondary concentration plant (SCP) that processes the HMC from both primary plants. Products from the SCP are further processed to finished mineral products at a nearby MSP in Koekenaap. Ilmenite product is further processed into titanium slag and pig iron at a two-furnace smelter at Saldanha, Western Cape, South Africa which is two hundred kilometers south of Koekenaap. The KZN operations have an open pit hydraulic mine at Fairbreeze with a primary gravity concentration plant, a MSP at nearby Empangeni alongside a two-furnace smelter complex, and export facilities at the port of Richards Bay.
In Australia, the Northern Operations consist of the Cooljarloo dredge mine and floating primary gravity concentration plant, and the Chandala metallurgical complex, consisting of a mineral separation plant and SR plant. The Southern Operations consist of a dry open pit mine and primary concentration at Wonnerup and a mineral separation plant at Bunbury.
The Eastern Operations in the Murray Basin of Australia consists of a dry open pit mine at Atlas Campaspe and a mineral separation plant at Broken Hill, NSW. The Snapper mine ceased production in April 2022 after 12 years of production. The Gingko and Crayfish mines ceased production in June 2024 after 20 years of production. Construction at Atlas commenced in 2022 and ramped up to full production in the first quarter of 2023. The Atlas Campaspe mine is abundant in natural rutile and high value zircon and will be a significant source of high-grade ilmenite suitable for direct use or upgraded feedstock production.

TABLE OF CONTENTS
S-K Subpart 1300 requires us to describe our rights to access and mine the minerals we report as reserves and to disclose any change in mineral tenure of material significance. Our heavy mineral exploration and mining activities in South Africa and Australia are regulated by the South African Department of Mineral Resources, the Western Australia Department of Mines, Petroleum and Exploration, and the New South Wales Department of Primary Industries and Regional Development - Resources. All exploration and mining activities are subject to multiple levels of environmental regulatory review, including approvals of environmental plans and public comment periods as pre-conditions to granting of mineral tenure.
Mineral Tenure - South Africa
Our two South African mineral sand mining processing chains are operated by Namakwa Sands and KZN Sands, both indirect, wholly-owned subsidiaries of Tronox Holdings plc. The South African Department of Mineral Resources and Energy (“DMRE”) is the regulatory administrator of mineral rights in South Africa, subject to the provisions of the Mineral and Petroleum Resources Development Act (“MPRDA”), No. 28 of 2004, as amended in 2016. The MPRDA vests all mineral rights in South Africa in the national government and establishes conditions for the acquisition and maintenance of prospecting and mining rights. Prospecting rights and mining rights may only be granted by the DMRE. Prospecting rights are granted for a maximum period of five years and can be renewed once for an extension of up to three years. Prospecting rights may be revoked for non-compliance with the terms of the prospecting right.
Mining right applications require additional approvals by the Department of Environmental Affairs (“DEA”) of an Environmental Management Program (“EMP”) and an Integrated Water and Land Use License.
Mining rights are valid for up to 30 years and may be extended by 30-year renewals, subject to compliance with conditions established in the EMP and by the MPRDA. Environmental permitting and compliance are co-administered by the regional offices of DEA and Development Planning. All rights, licenses and permits for Namakwa Sands and KZN Sands are in good standing.
On the Western Cape of South Africa, Tronox holds mining rights over an area of 19,205 hectares (47,457 acres) and surface rights totaling 17,111 hectares (43,542 acres) at the active mining site near Brand-se-Baai, commonly referred to as our Namakwa Sands operation. On the Eastern coast of South Africa, Tronox controls mining and prospecting rights covering approximately 4,041 hectares (9,986 acres) at KZN, where surface access rights are either owned directly by KZN Sands or secured by agreements with Mondi Ltd. A further 4,790 hectares (11,836 acres) of prospecting rights are held by a direct, wholly-owned subsidiary of KZN Sands at the nearby Port Durnford and Waterloo project areas which we are currently in the process of converting into a mining right.
Mineral Tenure - Australia
Our Australian mineral properties are divided into the Northern and Southern Operations on the Swan Coastal Plain of Western Australia and the Eastern Operations in the Murray Basin of New South Wales and Victoria. Mining tenements in Australia are managed at the State or Territorial level. In Western Australia, Mining Leases, Exploration Licenses and Retention Licenses are granted and administered by the Western Australian Department of Mines, Petroleum and Exploration, and in New South Wales by the NSW Department of Primary Industries and Regional Development - Resources, under the authority of the Western Australian Mining Act 1978 and the New South Wales Mining Act 1992, respectively. Principal environmental authorities are the Western Australian Department of Water and Environmental Regulation and the NSW Environment Protection Authority.
At the Northern Operations in Western Australia, Tronox controls mining leases, exploration and other licenses and rights covering a total 45,322 hectares (111,993 acres). Mining and Public Environmental Review plans are approved for the Cooljarloo mine and approval to extend the environmental plans for Dongara were recently approved. Environmental Protection Agency approval of Cooljarloo West has also been approved. The main Cooljarloo Mining Lease covers 9,744 hectares (24,078 acres). We hold 11 mining leases at the Dongara project and one exploration license. Three older mining leases are held at our Jurien property, the site of a former heavy minerals open pit mine operated by another party in the 1970’s.
Tronox holds mining and exploration licenses totaling 512,410 hectares (1,306,693 acres) in the South Perth Basin and Murray Basin heavy mineral provinces of Australia.
The Southern Operations in the southwest of Western Australia comprises 29 mining leases, 1 exploration license, 2 retention licenses, 2 general purpose leases, and 2 miscellaneous licenses totaling 8,485 hectares.
Tronox holds 6 mining leases, 15 exploration licenses, and 2 retention licenses in our Eastern Operations in the Murray Basin of New South Wales and Victoria. The tenements cover approximately 435,900 hectares (4,359 sq km). Four mining leases west of Pooncarie, NSW cover approximately 6,800 hectares (16,803 acres) surrounding our rehabilitation sites at Snapper, Ginkgo and Crayfish. Two mining leases of 6,159 hectares are located at the Atlas Campaspe mining project in NSW.

TABLE OF CONTENTS
Mineral Sands - South Africa and Australia
HMS deposits are natural concentrations of granular minerals of high density (conventionally above about 2.85 gm/cm3). Titanium-rich HMS deposit source rocks are typically granitic and/or high-grade metamorphic crystalline rocks. The heavy mineral assemblage of a particular HMS deposit generally reflects the ilmenite, leucoxene, natural rutile and zircon contained in local and regional source rocks. Factors that influence the formation of HMS deposits include erosion of crystalline source rocks, fluvial transport to the coastline, longshore drift, coastal geomorphology, deposition of heavy minerals, and prolonged natural sorting of heavy minerals by water and wind, according to the density, size and shape of HM grains. Post-depositional geological processes that can affect the economic viability of a HMS deposit include in situ weathering, induration of the host sands, and natural preservation or destruction of the HMS deposit.
Not all heavy minerals have commercial value, and a distinction is made between the Total Heavy Minerals (“THM”) and VHM. Typical VHM assemblages include the titanium-iron oxide mineral, ilmenite (FeTiO3); rutile, a premium TiO2 feedstock mineral; leucoxene, a natural alteration product of weathered ilmenite; and zircon, a zirconium silicate (ZrSiO4) valuable for its use in a diverse range of industrial and construction applications. Other HM of commercial value, such as garnet, staurolite, kyanite and monazite, may be recovered as by-products.
Of interest recently is the potential use of monazite, both in contained ore bodies and in stockpiled sources located near the mineral separation processes at Namakwa Sands. Monazite has increasing commercial value due to a high concentration of rare earth metals which can be separated by well-established methods. Rare earths are expected to remain in high demand as demand grows for electric vehicles, wind turbines, and consumer goods that require rare earth-containing permanent magnets. We currently do not know the metallurgical recovery potential for the monazite as our processes have historically focused on traditional value minerals. Given the increasing importance of monazite, we are evaluating new processes to better understand the grade and recoverability of monazite in our mining tenements.
Reporting of Reserves and Resources
The following tables summarize our reserves and resources as well as their contained in situ total heavy minerals (THM) and heavy mineral (HM) assemblages as of December 31, 2025 based on long-term price assumptions. The sole purpose of the operational and related financial data presented is to demonstrate the economic feasibility of the mineral reserves for the purpose of reporting in accordance with subpart 1300 of Regulation S-K, and should not be used for other purposes. The information presented originates from comprehensive techno-economic modelling, which is subject to change as assumptions and inputs are updated, and as a result does not guarantee future operational or financial performance. Consistent with industry standards, Tronox values its mineral reserves based on the prices at which its titanium and zircon mineral products would sell on freely traded markets, as forecasted by third-party industry consultancies.
All of our reserves are reported on the basis of our 100% ownership of in-place, economically extractable ore, determined from comprehensive geological, mining, processing and economic models. Reserve classifications of proven or probable are based on the level of confidence in the appropriate resource estimates. Our residual resources are those areas of mineralized ground which have either had insufficient drilling to confidently define the shape, grade and recoverability of the valuable minerals as well as not yet having been subjected to a detailed assessment of the impact of validated “modifying factors” on the revenue generating potential of a deposit.
Our mineral resource and reserve estimates are based on extensive geological resource models modified by various mining and processing factors and assessed in a techno-economic model for commercial viability. This constitutes a Life-of-Mine-Plan (LOMP) for each operation. Our LOMP and reserve estimates are optimized with respect to anticipated revenues and costs. Assumptions are developed from our extensive experience and include mining parameters, processing recoveries, operating costs, foreign exchange, and rehabilitation. Each of our operations reconcile predicted mining and processing metrics with actual production and recovery data on a monthly basis. Our models are updated as necessary and used to determine ore boundaries based on economic assumptions, certain of which are set forth below the following tables. For reserves where there is substantial asset investment post the minerals production stage, parameters that best utilize the whole value chain may take precedence over maximizing value from the minerals business unit, therefore impacting the optimal mining shell and effective cut-off grade.
Not all HMS deposits are alike. Our reserves, as set forth in the table below, have a higher confidence level because we have undertaken sufficient drilling density and validation. Resources present unconfirmed continuity and variability in grade, HM assemblage, or other characteristics, as well as the indeterminate impact of modifying factors, and hence are not classified as reserves.
Within the broad category of resources, inferred resources have a lower level of geological confidence than do indicated resources with measured resources being the highest confidence level from a geological perspective. Only indicated resources and measured resources can be converted to reserves with proven reserves having a higher level of economically exploitable confidence than probable reserves. The following tables have been determined to be economically- exploitable by individuals

competent and qualified to act under the new disclosure requirements as “Qualified Persons.” Each of the Qualified Persons is an employee of an indirect, wholly owned subsidiary of the Company.
For clarity, in the tables below, our reserves have been excised from the resources as they can be proven to be profitably mined and processed. The remaining deposit exceeds cut-off grade, but have not yet been demonstrated to be profitable by virtue of either recoverable grade, operating cost or capital required to develop, are separately defined as resources.
The overall 2.5% decrease in resources at all operating sites in 2025 as compared to 2024 is primarily attributed to the reclassification of material into reserves at Cooljarloo and KZN.
The overall 0.8% decrease in reserves at all operating sites in 2025 as compared to 2024 is primarily attributed to mining depletion, which has been mostly offset by increases in reserves at Cooljarloo and KZN.

Abbreviations, Definitions, and Notations
Reserves —mineralized material inclusive of dilution, determined to be economically and legally exploitable as of December 31, 2025, classified as either Probable Reserves or Proven Reserves, based on level of confidence.
Resources – mineralized ground which has either had insufficient drilling to confidently define the shape, grade and recoverability of the valuable minerals as well as not yet having been subjected to a detailed assessment of the impact of validated modifying factors on the revenue generating potential of a deposit.
LOMP — Life-of-Mine-Plans (LOMPs) have been developed for each mine site by teams of Tronox professionals based on the mineral reserves and resources, realistic assumptions of geological, mining, metallurgical, economic, marketing, legal, environmental, social, governmental, engineering, operational and all other modifying factors in sufficient detail to demonstrate at the time of reporting that extraction is reasonably justified.
THM — total heavy minerals, densities >2.85 g/cm3 regardless of commercial value
VHM — valuable heavy minerals, including Ilmenite, Rutile, Leucoxene & zircon, reported as percentage of THM.
Minor computational discrepancies may be due to rounding.
Cooljarloo Dredge Mine reserves include Cooljarloo and Cooljarloo West
Key Assumptions — economic viability is determined by techno-economic modeling that integrates geological, analytical and geotechnical databases, mining parameters, metallurgical recoveries, known or forecast operating costs, cost of capital, and product sales prices at time of production. Historical sales prices by themselves are unreliable predictors of future prices, and our forecasts are based on our private contracts, internal and external market research.
Disclosures of mineral reserves traditionally include a cut-off grade, the grade in a mineral deposit below which material cannot be profitably mined and processed. However, economic exploitability is determined by many modifying factors other than grade, and most modern mining operations, including ours, use detailed computer models utilized by employees who possess the experience and technical expertise to identify what parts of a deposit are economically exploitable.
Production forecasts of commercial-quality titanium mineral and zircon concentrates from reserves are taken from our Life- of-Mine Plans. Mining recoveries are typically close to 100%, but metallurgical recoveries in each concentration step can vary widely, as a function of ore and mineral characteristics. We apply recovery factors based on actual operating data.
Mineral reserve estimates, life-of mine projections, and revenue assumptions are inherently forward-looking and subject to market conditions, uncertainties, and unanticipated events beyond our control.

Tronox has one active mine site at Cooljarloo that was originally controlled by a State Agreement Act with the State of Western Australia. This area was covered by State Agreement Act MSA 268 which was originally granted in 1989 for a period of 21 years. It was extended for a further 10-year term which expired in 2020. MSA 268 was replaced by Mining Lease M70/1398 which will expire in 2041.
Cooljarloo West is located within Mining Leases 70/1314 and 70/1333. Osprey is located within Mining Lease 70/1413. Granting of rights to mine are pending environmental approval.
The minerals in Western Australia belong to the Crown (the State of Western Australia) and Tronox is obligated to pay a 5% revenue- based royalty on saleable mineral products. This is factored into the valuation models and optimizations conducted by Tronox.
A private royalty of 10c/t of VHM is paid for a portion of the northern section of the Cooljarloo tenement. Based on the current mine plan, mining in this royalty agreement area will cease by 2025 and the amounts paid are not material to the business.
On Mining Lease 70/1333 Tronox agrees to pay the previous holder of the exploration lease a royalty of 1% of a previously agreed price for each tonne of Valuable Heavy Mineral recovered from the Mining Lease. The cost will also be immaterial to the business.
The Cooljarloo Mine is located at coordinates latitude 30°39'S and longitude 115°27'E.

TABLE OF CONTENTS
Infrastructure
The Brand Highway is a major bitumen road running from Muchea, just North of Perth up to Geraldton, a provincial city 450 km north of Perth. The road runs just past the Western boundary of the Chandala site and just past the Eastern boundary of the Cooljarloo mine site. It is suitable for all weather and wide loads.
There is a 132 kV power line that also runs from Perth to Geraldton which passes near the Chandala site and through the mine site. Tronox has a substation on its property that draws and reticulates 22 kV power from the sub-station connected to the main high voltage distribution line. At the various locations power is ultimately transformed down to 415 V. The same situation exists for Chandala and it gets power from the same main line.
Two gas pipelines run just a kilometer to the West of the Chandala site. They are referred to as the Dampier to Bunbury Natural Gas pipeline (DBNG) and also the Parmelia line which originates just south of Geraldton. The Chandala Mineral Separation Plant currently gets supply for driers and re-heaters from the Parmelia line.
The countryside surrounding both Chandala and Cooljarloo is relatively flat. This made the construction of buildings and fixed plant straightforward. Storage ponds for solid waste from the MSP were able to be made quite shallow only being a few meters above natural ground level.
There is a large freshwater aquifer (Yarragadee) immediately to the west of the Brand highway adjacent to the Chandala site. Tronox has a borefield there that supplies the licensed 1 megaliter per annum of water that the site requires. Even in times of severe drought, supply from this aquifer has never been at risk. Cooljarloo draws from an extensive field of relatively shallow bores and also an extension of the Yarragadee aquifer. To limit pumping distances, it has been preferable to have multiple smaller bores around the site since the dredging operation has travelled more than 40 km within the mining lease area since 1989. Tailings disposal at Cooljarloo is all placed behind the dredging operations and incorporated into the rehabilitated profile. There is a registered waste disposal pit where wastes from the MSP, the Synthetic Rutile plant and from the Kwinana pigment plant are licensed to be stored. These pits cells are constructed above the water table and are clay lined. When each cell is full it is capped to minimize the ingress and egress of water.
The Chandala operation utilizes two port facilities. The Port of Fremantle is used for export of bagged and containerized mineral products and the Port of Bunbury is used for bulk shipments. Tronox rents storage and warehousing facilities at or nearby to those sites.
For Cooljarloo there is a well-equipped modern permanent single person’s quarters (SPQ), capable of accommodating up to 160 people or approximately 70% of the work force. At Chandala, employees and contractors are primarily sourced from the Perth metropolitan and surrounding areas.

TABLE OF CONTENTS
Cooljarloo
The Cooljarloo tenements were originally pegged in 1972 by Kamilaroi Oil Company following the discovery of the Eneabba Deposits. They were subsequently obtained by Yalgoo Minerals Pty Ltd and Tific Pty Ltd in 1985 which became part of TiO2 Corporation NL (TiO 2).
In 1988 prior to mining commencing, the Cooljarloo Joint Venture was formed between Kerr-McGee Chemical Corp and Minproc Ltd, subsequent reorganizations of both partners led to 100% ownership under Tronox in 2012.
No geological data generated by owners prior to the formation of the Cooljarloo Joint Venture is in use.
Cooljarloo West
In 1990 drilling by Peko Exploration Ltd delineated a zone of deep low-grade mineralization but further drilling failed to intercept economic mineralization. The tenements were relinquished in 1992.
Image Resources later pegged the area which were acquired by Tronox in 2005. Drilling completed by Tronox in 2007 delineated the deposits named Woolka Road, Harrier and Kestrel and Resources and Reserves are based only on data generated by Tronox.

Mineral prices used in Reserve estimation are substantially in line with the prices for each of our products published quarterly by independent consulting companies.
(2) Conversion of in ground grade to saleable product yield (recovery), considering all the losses during mining and processing, is typically 85% for ilmenite, 88% for rutile, 79% for Leucoxene and 83% for zircon.
For a comparison of the reported reserves as of December 31, 2025 with the reserves as of December 31, 2024, see table on pag e 36. The increase in reserves in 2025 compared to 2024 is primarily attributable to the inclusion of Osprey and 33,000S satellite pits into reserves. This has offset depletion due to mining.
Condition of Property
The Cooljarloo project was established in 1988. Being situated on an historical coastline, the ore body is made up of conventional mineral sands strandlines and eminently suited to dredge mining and gravity concentration.
Since commencement, the operation has been running continuously and has thus far consumed 671 Mt of ore at approximately 2.77% HM grade. The current reserves are 304 Mt tons at 1.8% HM grade, which gives a further 15 years of life. The current resources, which are exclusive of reserves, are 239 Mt at 1.6% HM.
Extensive and systematic exploration drilling activities are conducted at Cooljarloo and adjacent deposits on an annual basis to upgrade resources and reserves. Final reserve delineation drilling is completed to a 50m x 40m or 50m x 20m spacing depending on the geological complexities of the orebody. Final drilling is completed three or more years in advance of the mining face to allow timely and accurate mine planning to be completed. Over the past 15 years there has been an average of 52,000 meters of drilling completely annually at Cooljarloo. Drilling will continue in 2026.
Cooljarloo mine has operated with 2 dredges in the one pond since 1999. The original Ellicott Cooljarloo1 dredge operates in tandem with the smaller capacity Neumann built Pelican dredge which was brought into service in 2012. These bucket wheel dredges operate in a purpose-built pond which sits within the ore mining limit. The original dredge and concentrator were sized to operate at 12 Mt per annum but the original dredge has progressively been expanded and addition of the second dredge has seen the project expand to a maximum of 25Mt per annum to counteract the impact of lower ore grades and also enable improved resource utilization through economies of scale and increased product values.
A wet concentrator also floats in the dredge pond and is on two pontoons covering 2,250 square meters. Spiral gravity concentrators separate the higher density valuable minerals from the lower density trash mineral and lowest density tailings quartz grains. The spiral circuit consists of five stages. Roughers, middlings, cleaners, recleaners and classifiers. Both dredges pump their feed simultaneously to the floating wet concentrator via floating pipelines and high voltage cables for power.
Over the past 37 years of operation the metallurgical circuitry of the wet plant has remained relatively unchanged save for expanding the throughput to approximately 2850 tph. This allowed the processing of lower grade ore which has been shown to have a better revenue to cost ratio compared to the original project assumptions. At the time of the capacity increase, spirals that were at the end of their useful life were replaced with more modern units, of higher efficiency, to cope with both additional throughputs, the lower average feed grade, higher clay fines in the ore and maintain an acceptable mineral recovery.
HMC at Cooljarloo is loaded by front end loader into 93 tonne triple road trains for haulage to the Chandala Mineral Separation Plant (MSP). Both the mine and MSP are based on physical separation processes. There is no need for chemical or physical alteration to achieve good product recovery and quality. Attritioning is a critical process step to ensure clean mineral surfaces that are responsive to the electrostatic HT separators. The attritioned HMC is presented by filter belt to a natural gas fired drier that not only removes the moisture but heats the mineral so that it is most responsive to the primary stage electrostatic separation circuit.
The unit operations at the MSP are many and varied but the significant ones are as follows:
42

TABLE OF CONTENTS
•vibrating and reciprocating woven wire screening;
•mechanical slurry attritioning;
•gas fired fluid bed drying, reheating and cooling;
•HT Roll, Coronastat and Plate electrostatic separators;
•Rare Earth Drum, Rare Earth Roll, Induced Roll and Semi-Lift magnetic separators;
•Hydrosizing; and
•spiral gravity and centrifugal jig concentrators.
The equipment and infrastructure at both Cooljarloo and Chandala are in good order having been upgraded several times such that the total throughput of the mining operation now averages 21 Mt per annum and whilst the MSP has not needed capacity increase, updated technology and implementation of continuous improvement programs have resulted in significant increases in mineral recoveries.
Since Cooljarloo is an operating mine and processing plant, capital is mostly a sunk cost. There is minor stay in business capital incurred annually and there is US$55M of capital forecast with the move to the nearby Cooljarloo West dredging orebody expected in approximately 2033.
Tronox Eastern Operations (Atlas-Campaspe)
Tronox Mining Australia Ltd is a subsidiary of Tronox Holdings plc and is the operator of Tronox Eastern Operations which includes:
•The Snapper, Ginkgo and Crayfish rehabilitation sites, located 110 km north of Wentworth in southwestern New South Wales, where former mineral sands mines are undergoing restoration following the completion of mining;
•The Atlas-Campaspe project in southwestern New South Wales, 120 km northeast of Mildura, where heavy mineral concentrates are currently produced from dry mining operations at Atlas and site development and approval activities have commenced for future mining operations at Campaspe;
•A rail siding and HMC stockpile facility at Ivanhoe, approximately 140 km northeast of the Atlas Mine, where HMC is dispatched to Broken Hill for further processing;
•Broken Hill Mineral Separation Plant in southwestern New South Wales, where the HMCs are separated into mineral products and either railed approximately 430 km to the Port of Adelaide or railed directly to Western Australia using the Trans Australian Railway; and
•Port of Adelaide, South Australia, where bulk mineral sands products from Broken Hill are loaded for export.
Mining tenements in Australia are managed at the State or Territorial level. In New South Wales, Mining Leases, Exploration Licenses and Assessment Leases are granted and administered by the New South Wales Department of Primary Industries and Regional Development - Resources.
The Development Consent for Atlas and Campaspe was granted in June 2014 and construction of the Atlas Project was completed in early 2023. The Atlas deposit is secured by Mining Lease 1767. The Campaspe deposit is secured by Mining Lease 1882 which was granted in September 2024.
The minerals in New South Wales belong to the Crown (the State of NSW) and Tronox is obligated to pay a 4% revenue-based royalty on all saleable minerals produced.
All the land encompassing the intended mining area has been purchased by Tronox so no mining compensation payments to landowners will be required as part of the Atlas-Campaspe Project.
The net book value of Atlas-Campaspe, inclusive of mining and beneficiary equipment located in New South Wales as well as relevant mining tenements, as of December 31, 2025 was $290 million.
The Atlas mine is located at coordinates latitude 33°53’S and longitude 143°21’E. The Campaspe mine is located at coordinates latitude 33°49’S and longitude 143°22’E.

Atlas
The Atlas mine site is located in southwestern New South Wales, 120 km northeast of Mildura and 90 km north of Balranald. Access to the license area is via the Balranald Ivanhoe Hwy, the Boree Plains – Gol Gol road and then through the official Atlas Mine Access Road. The Atlas mine consists of a centrally based Wet Concentrator Plant (WCP) and a Dry Mining Unit (DMU) both rated to 500 tph.
An on-site 200-person accommodation village has been constructed to house the workforce and consists of permanent and demountable buildings and facilities such as: Administration and Office Building; Workshops; Process Area Crib Room and Amenities; Gymnasium; Basketball Court and Main Store. Electrical power is supplied directly from a centralized 5 Mwh diesel generation system.
Hydrological investigations identified a bore field location at the Northern end of the mine path, approximately 5km from the central start-up pit location. This bore field supplies water for the mining operations and ancillaries. A total of seven bore pumps supply the required volume.
A RO Plant and potable water treatment plant sized to deliver 115m3/hour has been installed to supply wash water for the HMC and potable water for site buildings, wash pads and the accommodation village.
A communication building is located adjacent to the communication tower for telecom and the Local Area Network (LAN). Data and telephone connection between the communications building, process area, administration area and accommodation village are via a buried fiber optic cable.
HMC from the Atlas mine is transported by a combination of trucks and train. The road network consists of approximately 37 km of existing unsealed roads between the Atlas-Campaspe Mine site access road and the intersection with the sealed Balranald-Ivanhoe Road. The remaining section is a 138 km long bitumen road leading to the Ivanhoe rail siding. HMC is loaded into a train for transport to the Broken Hill Mineral Separation Plant (BH MSP) over approximately 301 km of railway.
Campaspe Project Status and Site Development Works
At the conclusion of mining at Atlas production is expected to transition to Campaspe. Detailed mine planning and final approvals are underway. The development of the Campaspe site and required plant to operate includes:
•fencing of the mine lease (47 km);

History
In the Murray Basin fine heavy mineral occurrences were identified from 1982 to 1986 by Rio Tinto. Subsequently many smaller, coarser and high-grade deposits were also identified, and these formed the first mineral sands mines to be developed in the region. Bemax Resources discovered the Ginkgo, Snapper and Crayfish deposits at Pooncarie in the early to mid-2000’s. Mining commenced at Ginkgo in 2005 and Snapper in 2010. Mining at Snapper was completed in April 2022, Crayfish was completed in July 2023 and Ginkgo was completed in June 2024.
The Atlas-Campaspe Project replaced production from the completed Snapper, Ginkgo and Crayfish deposits. Atlas commenced full production in early 2023.

For a comparison of the reported reserves as of December 31, 2025 with the reserves as of December 31, 2024, see table on page 36. The decrease in reserves in 2025 as compared to 2024 is primarily attributable to mining depletion.
Condition of Property
Construction at Atlas commenced in 2022 and ramped up to full production in the first quarter of 2023. The Atlas deposit is mined using a dry mining method for both the overburden stripping and ore extraction.
We believe the equipment and infrastructure (including the DMU, WCP and all associated infrastructure) at Atlas is in good condition.
Dry mining at Campaspe is expected to replace production from Atlas when Atlas finishes during 2028. Detailed design work and additional approvals are presently being undertaken.
Extensive and systematic exploration drilling activities have been conducted at Atlas and Campaspe on an annual basis to upgrade resources and reserves. Final reserve delineation drilling is completed to 100m x 20m spacing. Final drilling is completed three or more years in advance of the mining face to allow timely and accurate mine planning to be completed. As such, all drilling has been completed at Atlas. Final infill drilling has also been completed for the first five (5) years of mining at Campaspe. Over the past 13 years there has been an average of 50,000 meters of drilling completed annually at Tronox’s Eastern Operations. Drilling will continue at Campaspe and surrounding areas in 2026.
Namakwa Mine
Tronox Mineral Sands Pty Ltd is a subsidiary of Tronox Holdings Plc and holds 100% of the rights at the Namakwa Sands Operations, which is located along the west coast of the Western Cape province, South Africa. The Namakwa Sands Operations includes:
•The Northern operations consisting of the Namakwa Sands Mine at Brand-se-Baai and the Mineral Separation Plant at Koekenaap.
•The Southern operations that consist of the Smelting Operations at Saldanha Bay along with administrative headquarters.
Run of mine production at the Namakwa Sands Mine comes from two shallow open-cast mines where excavators and front-end loaders extract free-flowing and lightly cemented sand. The ore is conveyed to two primary concentrator plants (PCP) that utilize wet spirals to produce a heavy mineral concentrate. These concentrates are pumped to a secondary concentrator plant (SCP) where wet high-intensity magnetic separators (WHIMS) and spirals are used to produce a zircon-rich non-magnetic concentrate, and a magnetic concentrate comprising mainly ilmenite. An ilmenite rich secondary stream from the SCP is reprocessed at a separate plant called the UMM Plant to produce a crude ilmenite. SCP and UMM concentrates are separately trucked to and treated at the MSP near Koekenaap, where a series of magnetic and electrical high-tension separators are employed to produce finale saleable ilmenite, rutile, and zircon products. These products are transported from the Mineral Separation Plant to the Smelter using the Saldanha-Sishen railway network.
The Southern Operations consist of the administrative headquarters and smelter operations and are located 3 km from the Saldanha export harbor. The smelting process comprises the carbonaceous reduction of ilmenite using DC arc furnaces to produce titanium slag and pig iron. The received rutile and zircon products as well as the titanium slag are stored in on-site silos from where it is distributed in bag, container, or bulk shipment format.
Mining tenements in South Africa are managed at a national level. In the Western Cape, Mining Rights and Prospecting Rights are granted and administered by the South African Department of Mineral Resources and Energy (DMR&E).
The Mining Rights for Namakwa are shown in the table and figure below.

The net book value of the Namakwa Sands mine, inclusive of mining and beneficiary equipment located in the Western Cape of South Africa as well as relevant mining tenements, as of December 31, 2025 was $552 million. The Namakwa Sands Mine is located at coordinates 31°16’S and 17°54’E.
Location of Western Cape operations
Infrastructure
Potable water is sourced from the Olifants River Irrigation Scheme canal system. Water is distributed to the MSP and Brand-se-Baai (BsB) for process and domestic use. Water is pumped to BsB via a 56 km pipeline at the rate of 280 m3/h. This line also provides water to farmers along the line and rehabilitation areas at the Namakwa Sands Mine. Namakwa Sands holds servitude rights in the area adjacent to the tar sealed road between the Mineral Separation Plant and the Mine. Seawater is used in the primary and secondary separation processes and is pumped via the seawater pump station installation close to the Namakwa Sands Mine.

TABLE OF CONTENTS
ESCOM supplies the MSP via the 132 kV line from the Juno substation. A 132/22 kV, 20 MVA transformer from ESCOM supplies both the MSP and a local farm.
The minerals are transported with purpose-built trailers and trucks between the Namakwa Sands and the MSP at Koekenaap. The trucks travel on a tar seal road constructed for this purpose. A Sishen-Saldanha railway line connects the MSP and Smelter sites. The minerals are transported from the MSP to the Smelter/port storage in closed container trucks, to prevent mineral losses and contamination.
History
Exploration for heavy minerals along the coastal strip of southwest Africa led to the discovery and subsequent delineation of the Namakwa Sands deposit near Brand-se-Baai in 1987. In September 1994 Anglo Operations Ltd commenced mining and processing at the West mine ore body. In 2008 Exxaro Resources acquired the Namakwa operations from Anglo and then in 2012 Tronox acquired 74% of Namakwa Mineral Sands Pty Ltd. In 2021 Tronox acquired the whole of Namakwa Mineral Sands Pty Ltd.

Condition of Property
The operations at Namakwa Sands were originally established by Anglo in 1996 and have operated continuously since that time. Open-cast mining, also known as strip mining, both classified as surface mining techniques, takes place in two distinct areas known as the East and West Mines. The East Mine comprises predominantly shallow mineral sands stripping, whereas the West Mine entails shallow stripping of mineral sands followed by a deeper open-cast mining operation recovering lightly cemented materials to about 40 meters.
48

TABLE OF CONTENTS
More than 200,000 meters of drilling has been completed to date, to define the pre-mine Namakwa mineral resources base from surface down to bedrock. In-fill drilling, assaying and metallurgical test work will continue over the next decade with the strategy to upgrade current mineral resources to fully measured status, as well as converting mineral resources to mineral reserves, with a focus on proven mineral reserves realization.
The mining and mineral processing flowsheet and equipment of the Northern Operations have remained basically the same since the last throughput upgrade in 2008. The equipment and infrastructure at both mines are in sound working order, having been upgraded such that the total throughput of the mining operations now averages around 23 Mt per annum. A major mine development project, is to be operational in 2026 is currently in the execution stage to extract and beneficiate the deeper lying ore in the East Mine beneath the shallow sands that are nearing its end of life.
Other changes include minor equipment replacements and technology updates, as well as circuit re-configurations as part of an embedded continuous improvement drive. Most recently, a small standalone scavenger plant has been added to the SCP flowsheet to augment attritioned magnetic concentrate production by consuming excess unattritioned ilmenite produced from the WHIMS circuit. Routine work maintenance programs are solidly entrenched, being directed by physical asset care plans targeting the maximum life and efficiency of plant, property and equipment holistically.
KZN Sands
Tronox KZN Sands Operations, which are located along the east coast of the Kwa-Zulu Natal province, South Africa are wholly owned subsidiaries of Tronox Holdings Plc, and include the:
•Fairbreeze Mine, immediately south of the Mtunzini township with the Primary Wet Plant (PWP) situated a further 8 km south of Mtunzini.
•Central Processing Complex (CPC), 50 road km north of Mtunzini, just outside the town of Empangeni, is where heavy mineral concentrates are processed into mineral products and ilmenite is further converted to titanium rich slag and pig iron in two direct current arc furnaces. The laboratory and mineral testing facilities are also located at CPC.
A hybrid mining method is employed at Fairbreeze Mine, utilizing track dozers to break lightly cemented ore layers in combination with high- pressure hydraulic mining using water monitor guns to pump slurried ore to the Primary Wet Concentrator (PWP) for wet gravity recovery of heavy minerals.
The resultant heavy mineral concentrate is trucked to the CPC, which is configured with relatively standard equipment to produce saleable ilmenite, rutile and zircon products. The ilmenite is dispatched to the bordering smelting process encompassing the carbonaceous reduction of ilmenite using DC arc furnaces to produce titanium slag and pig iron. The rutile and zircon products as well as the titanium slag are stored in on-site silos from where it is distributed in bag, container, or bulk shipment format destined for the Richards Bay harbor.
Mining tenements in South Africa are managed at a national government level. In KwaZulu-Natal, Mining Rights and Prospecting Rights are granted and administered by the regional office of the South African Department of Mineral Resources and Energy (DMRE).
The Mining Rights for Fairbreeze are shown in the table and figure below.

TABLE OF CONTENTS
Infrastructure
Fresh water is sourced from the Mhlathuze River upgraded installation that originally supplied the Hillendale Mine. This system was upgraded to a pipeline of 750 mm nominal diameter over approximately 33 km to the Fairbreeze Mine and discharging into the raw water dam, from where it is further distributed for mining and minerals processing, as well as potable use.
Bulk electricity supply for the Fairbreeze Mine is from 88 kV and 132 kV ESCOM power lines that run adjacent to the residue storage facilities and feeds the Fairbreeze substation.
Access to the PWP is from off ramps at Bridge 4 on the national highway N2, south of the town of Mtunzini. Road transport for HMC to the MSP at Empangeni, a distance of 50 km, is along the N2 highway utilizing side tipping trucks. Gypsum waste and MSP sand tailings are returned on the backhaul. There is another route between Fairbreeze and the MSP along the R102 that can be used in emergencies. Railway networks in and around the region are suitable for the cargo requirements of the harbor and local industry and are directly connected to the national network for import/export purposes. The Richards Bay harbor operates a very large coal-handling terminal and controls a wide range of import and export cargos. Durban also has port facilities that Tronox uses to export containerized and bagged product from.
History
Natal Mineral Sands (NMS), prospected for mineral sands on Hillendale and Fairbreeze in the northern coast of KwaZulu-Natal during the 1980’s. Iscor Limited purchased NMS in 1994 and mining activities commenced in 2001 at the Hillendale Mine. In 2012, Tronox announced the acquisition of 74% of KZN Mineral Sands operations. Production commenced at Fairbreeze in 2015 and in 2021 Tronox acquired the whole of the remaining portion it did not own of the KZN Sands operations.

Condition of Property
In 2001, the Hillendale Mine started to supply HMC concentrate to the CPC, in Empangeni for further minerals processing to saleable mineral products. In 2015 after its useful life, and a production-break, most of the Hillendale Mine’s useful, movable equipment was transferred to the nearby newly established Fairbreeze Mine. Mining at Hillendale Mine was exclusively hydraulic mining, but due to the partially semi-consolidated nature of the Fairbreeze ore bodies, a hybrid open-cast mining method is employed at Fairbreeze Mine, utilizing track dozers to break up the ore where required to assist high- pressure hydraulic mining using water monitor guns to pump slurried ore to the PWP for wet gravity recovery of heavy minerals.
Close to 90,000 meters of drilling has been completed to date to define the pre-mine Fairbreeze mineral resources base from surface down to bedrock. Drilling, assaying and metallurgical test work will continue over the next decade with the strategy to upgrade current mineral resources to fully measured status, as well as converting mineral resources to mineral reserves, with a focus on proven mineral reserves realization. The equipment and infrastructure of the Fairbreeze Mine and PWP are in sound working order, having been upgraded as such that the total throughput of the mining operation averaged around 10 Mt per annum for the initial Phase 1 upgrade. Freshly supplied HMC continued to utilize the existing infrastructure at the CPC, Empangeni, being a fully functional mineral separation plant for zircon, ilmenite and rutile products and smelting operations using two DC arc furnaces to produce of TiO2 slag and pig iron, on the same site.
More recently a Phase 2 expansion of the operation at Fairbreeze Mine was commissioned in order to maintain heavy mineral concentrate (HMC) production due to lower THM grades in the ore. The expansion involves increasing the mining and PWP processing rate to about 16 Mt per annum, which require upgrades to the upfront desliming circuit, a further upgrade of the clay fines thickening and residue disposal equipment, rougher spiral capacity, increased concentrator building and additional process water pumping capacity. Mineral recoveries will be maintained following the expansion as will product quality. A residue storage facility (RSF) called MegaSebeka is currently in place and operational, however with the recent increase in mineral reserves, mine life and planned mining rate, an adjacent area called the Everglades RSF will be constructed nearby.
Otherwise, the MSP used to convert HMC into saleable mineral products is the same that was used for the KZN project’s original mining at Hillendale. Other changes include minor equipment replacements and technology updates, as well as circuit re-configurations as part of an embedded continuous improvement drive. Routine work maintenance programs are solidly entrenched, being directed by physical asset care plans targeting the maximum life and efficiency of plant, property and equipment holistically.

Executive Overview
Tronox Holdings plc (referred to herein as "Tronox", "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 TiO 2 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 TiO 2 at our seven pigment facilities located in the United States, Australia, Brazil, UK, France 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 TiO 2 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:
Fourth quarter revenue increased 8% compared to the prior year, driven by higher sales volumes of TiO 2 and zircon, higher sales of other products, and favorable exchange rate impacts partially offset by lower average selling prices, including mix of TiO 2 and zircon. For the fourth quarter of 2025 as compared to the fourth quarter of 2024, TiO 2 revenue increased 8%, driven by a 13% increase in volumes and a 3% exchange rate tailwind partially offset by an 8% decrease in average selling prices including mix. Zircon revenue increased 4% driven by a 27% increase in volumes partially offset by a 23% decrease in average selling prices including mix. Revenue from other products increased 10% mainly due to higher sales volumes of pig iron. Gross profit decreased for the fourth quarter of 2025 as compared to the fourth quarter of 2024 due to unfavorable impacts of average selling prices and mix and higher production costs and freight costs. These unfavorable impacts were partially offset by higher TiO 2 and zircon sales volumes and favorable exchange rate movements.
Sequentially, revenue increased 4% in the fourth quarter of 2025 compared to the third quarter of 2025 driven by higher sales volumes of TiO 2 and zircon partially offset by unfavorable average selling prices including mix and lower sales volumes of heavy mineral concentrate tailings. TiO 2 revenue increased 5% in the fourth quarter of 2025 compared to the third quarter of 2025 driven by a 9% increase in volumes partially offset by a 4% decline in average selling prices including mix. Zircon revenue increased

32% driven by a 42% increase in volumes partially offset by an 10% decrease in average selling prices including mix. Other products revenues decreased 17% sequentially primarily due to higher heavy mineral concentrate tailings sales in the third quarter. Gross profit decreased sequentially from the third quarter of 2025 to the fourth quarter of 2025 due to lower average selling prices and mix, lower other products revenue partially offset by higher sales volumes of TiO 2 and zircon and improved production costs.

(1) EBITDA, Adjusted EBITDA and Adjusted EBITDA as a % of Net Sales are Non-U.S. GAAP financials 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.
Net sales of $2,898 million for the year ended December 31, 2025 decreased by 6% compared to $3,074 million for the same period in 2024. Revenue decreased primarily due to both lower sales volumes and average selling prices of TiO 2 and zircon. Net sales by type of product for the years ended December 31, 2025 and 2024 were as follows:

The table below presents reported revenue by product:

| Year Ended December 31, |  |  |  |
(Millions of dollars, except percentages) | 2025 |  | 2024 |  | Variance |  | Percentage
TiO 2 | $ | 2,298 |  |  | $ | 2,407 |  |  | $ | (109) |  |  | (5) | %

For the year ended December 31, 2025, TiO 2 revenue decreased $109 million, or 5%, compared to the prior year due to a $83 million decrease in average selling prices including mix and a $54 million decrease in sales volumes. Foreign currency positively impacted TiO 2 revenue by $28 million due primarily to the strengthening of the Euro. Zircon revenues decreased $48 million primarily due to a 14% decrease in average selling prices including mix and a 1% decrease in sales volumes. Other products revenue decreased primarily due to a decrease in sales volumes of heavy mineral concentrate tailings.
Gross profit of $269 million for the year ended December 31, 2025 was 9.3% of net sales compared to 16.8% of net sales for the same period in 2024. The decrease in gross margin is primarily due to:
•the unfavorable impact of 4 points due to a decrease in TiO 2 and Zircon selling prices,
•the unfavorable impact of 3 points due to higher production costs and freight costs, and
•the unfavorable impact of 1 point due to decreased volumes of TiO 2 and Zircon, partially offset by
•the favorable impact of 1 point due to changes in foreign currency exchanges rates, primarily as a result of the South Africa Rand and Australian dollar.
Restructuring and other charges of $232 million for the year ended December 31, 2025 was related to both the Botlek and Fuzhou plant closures. Refer to Note 3 of notes to consolidated financial statements for further details.
Selling, general and administrative ("SG&A") expenses decreased $6 million when comparing the year ended December 31, 2025 to the prior year. The SG&A expenses decrease was primarily driven by a $7 million decrease in employee costs and a $3 million decrease in travel and entertainment expenses partially offset by a $4 million increase due to loss on asset disposals. The remaining net difference was driven by individually immaterial amounts.
Loss from operations for the year ended December 31, 2025 of $253 million, decreased by $472 million or 216% compared to income from operations of $219 million for the same period in 2024 which is primarily attributable to lower sales volumes and lower average selling prices of both TiO 2 and zircon as well as restructuring and other charges of $232 million partially offset by lower selling, general and administrative expenses.
Interest expense for the year ended December 31, 2025 increased $22 million compared to the same period in 2024 primarily due to the increase in both the outstanding short-term debt balances period over period and the new senior secured notes entered into in September 2025.
Interest income for the year ended December 31, 2025 decreased $4 million compared to the same period in 2024 primarily due to an overall decrease in our cash balances period over period.
Other (expense) income, net for the year ended December 31, 2025 primarily consisted of approximately $13 million of fees associated with the utilization of the Securitization Facility, $6 million of net realized and unrealized foreign currency losses and $2 million of pension expense related to pension related interest costs and amortization of actuarial gains/losses offset by expected return on plan assets. 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, Brazil, the Netherlands and the United Kingdom. Future provisions for income taxes associated with 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 other specific tax assets.
The effective tax rate was (3)% and 174% for the years ended December 31, 2025 and 2024, respectively. The effective tax rates for the year ended December 31, 2025 and 2024 are influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, non-taxable income and expenses, withholding taxes, prior year accruals, and our jurisdictional mix of income at tax rates different than the U.K. statutory rate. Additionally, the effective tax rate for the year ended December 31, 2024 is significantly influenced by the application of valuation allowances against deferred tax assets in Brazil and the Netherlands. Refer to Note 6 of notes to consolidated financial statements for further information.

TABLE OF CONTENTS
Net loss as a percentage of net sales was (16.3)% for the year ended December 31, 2025 as compared to (1.8)% for the year ended December 31, 2024. The primary driver of the year-over-year increase in Net loss as a percentage of net sales is the restructuring charges related to the Botlek and Fuzhou plant closures as well as the lower gross profit due to both lower sales volumes and average selling prices and higher production costs and freight costs. Adjusted EBITDA as a percentage of net sales was 11.6% for the year ended December 31, 2025 as compared to 18.3% in the prior year due to the lower gross margin as a result of decreases in average selling prices, including mix for both TiO 2 and zircon and a decrease in TiO 2, zircon and other product sales volumes.
Year Ended December 31, 2024 Compared to the Year Ended December 31, 2023
A discussion of our results of operations for the year ended December 31, 2024 versus December 31, 2023 is included in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operation”, included in our Annual Report on Form 10-K for the year ended December 31, 2024.
Other Comprehensive Income (Loss)
There was an other comprehensive income of $167 million for the year ended December 31, 2025 compared to other comprehensive loss of $74 million for the year ended December 31, 2024. This increase in comprehensive income was primarily driven by the favorable foreign currency translation adjustments of $178 million for the year ended December 31, 2025 as compared to unfavorable foreign currency translation adjustments of $80 million in the prior year. Additionally, we recognized net losses on derivative instruments of $12 million in the year ended December 31, 2025 as compared to net losses on derivative instruments of $2 million in the prior year as well as pension and postretirement gain of $1 million for the year ended December 31, 2025 as compared to pension and postretirement gains of $8 million in the prior year.

Liquidity and Capital Resources
During 2025, our liquidity increased by $96 million to $674 million.
The table below presents our liquidity, including amounts available under our credit facilities, as of the following dates:

| December 31, 2025 |  | December 31, 2024
Cash and cash equivalents | $ | 199 |  |  | $ | 151 |
Available under the Cash Flow Revolver | 332 |  |  | 305 |
Available under the RMB Credit Facility | 72 |  |  | 42 |
Available under the Emirates Revolver | 67 |  |  | 63 |

Total | $ | 674 |  |  | $ | 578 |

1 - The SABB Credit Facility was cancelled in September 2025.
Historically, we have funded our operations and met our commitments through cash generated by operations, issuance of secured and unsecured notes, bank financings, borrowings under lines of credit and other financing arrangements. 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 15 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 including tariffs, 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 appropriate liquidity.
Working capital (calculated as current assets less current liabilities) was $1.3 billion at December 31, 2025, compared to $1.3 billion at December 31, 2024.
As of and for the year ended December 31, 2025, the non-guarantor subsidiaries of our Senior Notes due 2029 and Senior Secured Notes due 2030 represented approximately 18% of our total consolidated liabilities, approximately 44% of our total consolidated assets, approximately 45% of our total consolidated net sales and approximately 53% of our Consolidated EBITDA

TABLE OF CONTENTS
(as such term is defined in the respective Indenture). In addition, as of December 31, 2025, our non-guarantor subsidiaries had $846 million of total consolidated liabilities (including trade payables but excluding intercompany liabilities), all of which would have been structurally senior to the 2029 Notes and 2030 Notes. See Note 15 of notes to consolidated financial statements for additional information.
At December 31, 2025, we had outstanding letters of credit and bank guarantees of $155 million. See Note 20 of notes to 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.
Our credit rating with Moody’s changed from Ba3 stable outlook at December 31, 2024 to B2 negative outlook at December 31, 2025. Our credit rating with Standard & Poor's rating changed from B positive and stable outlook at December 31, 2024 to CCC+ and negative outlook at December 31, 2025. See Note 15 of notes to 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 December 31, 2025, 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 various mine extension and development projects, continued reductions in our debt and continued dividends.
Repatriation of Cash
At December 31, 2025, we held $199 million in cash and cash equivalents in these respective jurisdictions: $7 million in the United States, $33 million in South Africa, $57 million in Australia, $35 million in Brazil, $19 million in Saudi Arabia, $21 million in China, $26 million in Europe and $1 million in India. Our credit facilities limit transfers of funds from subsidiaries in the United States to certain foreign subsidiaries. In addition, at December 31, 2025, we held approximately $12 million of restricted cash of which $10 million is in the US related to the annual payment for the Hawkins Point Plant environmental liability (refer to Note 20 of notes to consolidated financial statements for further details), with the remaining balance in South Africa related to a profit-sharing arrangement and in Australia related to performance bonds.
At December 31, 2025, 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. The Company has removed its assertion that earnings in China are indefinitely reinvested, and the withholding tax accruals for potential repatriations from that jurisdiction are now reflected in the effective tax rate reconciliation in Note 6 to the consolidated financial statements.
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 year ended December 31, 2025, we made no repurchases of the Company's stock.
Cash Dividends on Ordinary Shares
On February 11, 2026, the Board declared a quarterly dividend of $0.05 per share to holders of our ordinary shares at the close of business on February 23, 2026, which will be paid on April 2, 2026.
Inventory Financing Arrangement
On July 29, 2025, we entered into an inventory financing arrangement whereby we agree with our counterparty to sell certain inventory, with short payment terms, and subsequently we repurchase such inventory at an agreed upon price with terms not to
58

TABLE OF CONTENTS
exceed 360 days. The agreed upon repurchase price is generally calculated as the original sale price plus financing charges and a nominal spread. As of December 31, 2025, we had financed inventory of $50 million and $2 million of accrued interest, which were included in “Obligations under inventory financing arrangements” and “Accrued Liabilities”, respectively, on the Consolidated Balance Sheets. We have $2 million for the year ended December 31, 2025 of financing charges that were recorded within “Interest Expense” on the Consolidated Statement of Operations.
In January 2026, we repaid in cash our payable due to the counterparty and shortly thereafter, we entered into a new inventory financing arrangement on terms similar to those referenced above. The amount financed in this new transaction remains at $50 million.
Debt Obligations
On September 26, 2025, Tronox Incorporated, a Delaware corporation (the "Issuer"), a wholly owned indirect subsidiary of Tronox Holdings plc, closed an offering of $400 million aggregate principal amount of its 9.125% senior secured notes due 2030 (the "Notes"). The Notes were offered at par and issued under an indenture dated as of September 26, 2025 (the "Indenture") among the Issuer and the Company and, as described below, certain of the Company's restricted subsidiaries as guarantors and Wilmington Trust, National Association in its capacity as trustee and collateral agent.
The Indenture and the Notes provide, among other things, that the Notes are guaranteed by the Company and certain of the Company's restricted subsidiaries, subject to certain exceptions. The Notes are scheduled to mature on September 30, 2030, subject to a springing maturity date that is 91 days prior to the stated maturity date of the Company's 4.625% Senior Notes due 2029, if on such date, the aggregate principal amount of the Senior Notes due 2029 outstanding is greater than $250 million. The terms of the Indenture, among other things, limit, in certain circumstances, the ability of the Issuer and the ability of the Company and its restricted subsidiaries to: incur secured indebtedness, incur indebtedness at a non-guarantor subsidiary, engage in certain sale-leaseback transactions and merge, consolidate or sell substantially all of their assets.
At December 31, 2025 and 2024, our short-term debt and long-term debt, net of unamortized discount and debt issuance costs was $3.2 billion and $2.9 billion, respectively.
At December 31, 2025 and 2024, our net debt (the excess of our debt over cash and cash equivalents) was $3.0 billion and $2.7 billion, respectively.
As of February 13, 2026, the total outstanding principal balance on our short-term debt facilities was approximately $77 million.
See Note 15 of notes to consolidated financial statements for further details.
Off-Balance Sheet Arrangements
In March 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 extended 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 a result of the Second Amendment, and 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.
In March 2025, the Securitization Facility was amended (the "Fifth Amendment") to extend the program term to March 2028.
See "Note 9 - Accounts Receivable Securitization Program" in notes to consolidated financial statements for further details regarding this off-balance sheet program.
Cash Flows
Years Ended December 31, 2025 and 2024

TABLE OF CONTENTS
The following table presents cash flow for the periods indicated:

| Year Ended December 31,
| 2025 |  | 2024
| (Millions of U.S. dollars)
Net cash provided by operating activities | $ | 60 |  |  | $ | 300 |
Net cash used in investing activities | (328) |  |  | (343) |
Net cash provided by (used in) financing activities | 321 |  |  | (71) |
Effect of exchange rate changes on cash and cash equivalents and restricted cash | 6 |  |  | (7) |
Net increase (decrease) in cash and cash equivalents | $ | 59 |  |  | $ | (121) |

Cash Flows provided by Operating Activities — Cash provided by our operating activities is driven by net loss adjusted for non-cash items and changes in working capital items. The following table summarizes our net cash provided by operating activities for 2025 and 2024:

| Year Ended December 31,
| 2025 |  | 2024
| (Millions of U.S. dollars)
Net loss | $ | (473) |  |  | $ | (54) |
Net adjustments to reconcile net loss to net cash provided by operating activities | 635 |  |  | 457 |
Income related cash generation | 162 |  |  | 403 |
Net change in assets and liabilities | (102) |  |  | (103) |
Net cash provided by our operating activities | $ | 60 |  |  | $ | 300 |

Net cash provided by operating activities was $60 million in 2025 as compared to $300 million in 2024. The decrease of $240 million period over period is primarily due to a $241 million decrease in income related cash generation and a decrease of $1 million in the use of cash for net assets and liabilities. The lower use of cash for working capital was primarily driven by decreases in the use of cash for inventories of $89 million, increase in the cash provided by prepaid and other current assets of $19 million and a decrease in the use of cash for long-term other assets and liabilities for $16 million partially offset by increases in the use of cash for accounts payable and accrued liabilities of $15 million, an increase in the use of cash for restructuring payments of $76 million and a decrease in cash provided by accounts receivable of $20 million and a change of $12 million in net changes in income tax payables and receivables.
Cash Flows used in Investing Activities — Net cash used in investing activities for the year ended December 31, 2025 was $328 million as compared to $343 million for the year ended December 31, 2024. The $15 million decrease in use of cash year over year is primarily driven by lower capital expenditures of $341 million during the current year as compared to $370 million in the prior year. Additionally, there was $15 million of cash received for the repayment of our loan with AMIC related to the titanium slag smelter facility in the current year and proceeds of $21 million from the sale of a royalty interest in certain Canadian mineral properties in the prior year.
Cash Flows provided by (used in) Financing Activities — Net cash provided by financing activities during the year ended December 31, 2025 was $321 million as compared to cash used in financing activities of $71 million for the year ended December 31, 2024. The current year is primarily comprised of net proceeds from long-term debt of $371 million and net proceeds from inventory financing arrangement of $50 million partially offset by dividend payments of $48 million and net repayments of short-term debt of $44 million. The prior year was primarily comprised of dividends paid of $80 million and total net proceeds of $26 million of long-term debt and short-term debt.
Years Ended December 31, 2024 and 2023
A discussion of our cash flows for the year ended December 31, 2024 versus 2023 is included in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Cash Flows”, included in our Annual Report on Form 10-K for the year ended December 31, 2024.

(1)We calculated our various term loan facilities' interest at a SOFR plus an applicable margin. See Note 15 of notes to our consolidated financial statements.
(2)Includes obligations to purchase requirements of process chemicals, supplies, utilities and services. We have various purchase commitments for materials, supplies, and services entered into in the ordinary course of business. Included in the purchase commitments table above are contracts, which require minimum volume purchases that extend beyond one year or are renewable annually and have been renewed for 2026. Certain contracts allow for changes in minimum required purchase volumes in the event of a temporary or permanent shutdown of a facility. We believe that all of our purchase obligations will be utilized in our normal operations.
(3)The table excludes contingent obligations, as well as any possible payments for uncertain tax positions given the inability to estimate the possible amounts and timing of any such payments.
(4)Pension and other post-retirement benefit ("OPEB") obligations of $224 million include estimates of pension plan contributions and expected future benefit payments for unfunded pension and OPEB plans. Pension plan contributions are forecasted for 2026 only. Expected future unfunded pension and OPEB benefit payments are forecasted only through 2035. Contribution and unfunded benefit payment estimates are based upon current valuation assumptions. Estimates of pension contributions after 2026 and unfunded benefit payments after 2035 are not included in the table because the timing of their resolution cannot be estimated. Refer to Note 23 in notes to consolidated financial statements for further discussion on our pension and OPEB plans.
(5)Amounts are shown at the undiscounted and uninflated values.
Non-U.S. GAAP Financial Measures
EBITDA, Adjusted EBITDA, Adjusted net loss attributable to Tronox and Diluted adjusted net income per share attributable to Tronox, which are used by management to measure performance, are not presented in accordance with U.S. GAAP. We define EBITDA as net loss 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 income attributable to Tronox as net loss attributable to Tronox excluding the impact of nonrecurring items which 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 income per share excluding the impact of nonrecurring items which 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 income attributable to Tronox and Diluted adjusted net income per share attributable to Tronox 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 income attributable to Tronox and Diluted adjusted net income per share attributable to Tronox differently than we do, EBITDA, Adjusted EBITDA, Adjusted net income attributable to Tronox and Diluted adjusted net income per share attributable to Tronox, 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;
61

TABLE OF CONTENTS
•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.

Critical Accounting Policies and Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions regarding matters that are inherently uncertain and that ultimately affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. The estimates and assumptions are based on management’s experience and understanding of current facts and circumstances. These estimates may differ from actual results. Certain of our accounting policies are considered critical, as they are both important to reflect our financial position and results of operations and require significant or complex judgment on the part of management. The following is a summary of certain accounting policies considered critical by management.
Asset Retirement Obligations
To the extent a legal obligation exists, an asset retirement obligation (“ARO”) is recorded at its estimated fair value and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Because AROs represent financial obligations to be settled in the future, uncertainties exist in estimating the timing and amount of the associated costs to be incurred. Fair value is measured using expected future cash outflows, adjusted for expected inflation and discounted at our credit-adjusted risk-free interest rate. No market-risk premium has been included in our calculation of ARO balances since we can make no reliable estimate. Management believes these estimates and assumptions are reasonable; however, they are inherently uncertain. Refer to Notes 19 to the consolidated financial statements for a summary of the estimates and assumptions utilized. At December 31, 2025, AROs were $215 million of which the long-term portion of $198 million is recorded in "Asset retirement obligations" and the short-term portion of $17 million is recorded in "Accrued liabilities" in the Consolidated Balance Sheet.
Environmental Matters
Liabilities for environmental matters are recognized when it is probable that a liability has been incurred and the related 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 or reasonably possible environmental loss in excess of our recorded liabilities. At December 31, 2025, environmental liabilities (both short term and long term) were $55 million, of which the long-term portion of $39 million and the short-term portion of $16 million are recorded in "Environmental liabilities" and "Accrued liabilities", respectively, in the Consolidated Balance Sheet.
For further discussion, see Environmental Matters included elsewhere in this section entitled, "Management’s Discussion and Analysis of Financial Condition and Results of Operations" and Notes 2 and 20 to the consolidated financial statements.
Income Taxes
We have operations in several countries around the world and are subject to income and similar taxes in these countries. The estimation of the amounts of income tax involves the interpretation of complex tax laws and regulations and how foreign taxes affect domestic taxes, as well as the analysis of the realizability of deferred tax assets, tax audit findings and uncertain tax
64

TABLE OF CONTENTS
positions. Although we believe our tax accruals are adequate, differences may occur in the future, depending on the resolution of pending and new tax matters.
Deferred tax assets and liabilities are determined based on temporary differences between the financial statement amounts and tax bases of assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes in our estimates in the valuation allowance with a corresponding adjustment to earnings or other comprehensive income (loss) as appropriate. ASC 740, Income Taxes, requires that all available positive and negative evidence be weighed to determine whether a valuation allowance should be recorded.
The amount of income taxes we pay are subject to ongoing audits by federal, state and foreign tax authorities, which may result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We assess our income tax positions and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances and information available at the reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, we record the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties are accrued as part of tax expense, where applicable. If we do not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized.
See Notes 2 and 6 to the consolidated financial statements for additional information.
Contingencies
From time to time, we may be subject to 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 or 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. Such contingencies are significant and the accounting requires considerable management judgments in analyzing each matter to assess the likely outcome and the need for establishing appropriate liabilities and providing adequate disclosures.
Refer to Notes 2 and 20 to the consolidated financial statements for additional information.
Long-Lived Assets
Key estimates related to long-lived assets (property, plant and equipment, mineral leaseholds, and intangible assets) include useful lives, recoverability of carrying values, and the existence of any asset retirement obligations. As a result of future decisions, such estimates could be significantly modified. The estimated useful lives of property, plant and equipment range from two to forty years, and depreciation is recognized on a straight-line basis. Useful lives are estimated based upon our historical experience, engineering estimates, and industry information. These estimates include an assumption regarding periodic maintenance. Mineral leaseholds are depleted over their useful lives as determined under the units of production method. Intangible assets with finite useful lives are amortized on the straight-line basis over their estimated useful lives. The amortization methods and remaining useful lives are reviewed quarterly.
We evaluate the recoverability of the carrying value of long-lived assets that are held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Under such circumstances, we assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are not sufficient, we calculate the impairment amount by discounting the projected cash flows using our weighted-average cost of capital. For assets that satisfy the criteria to be classified as held for sale, an impairment loss, if any, is recognized to the extent the carrying amount exceeds fair value, less cost to sell. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined.
Pension and Postretirement Benefits
We provide pension benefits for qualifying employees in the United States and internationally, with the largest in the United Kingdom. Because pension benefits represent financial obligations that will ultimately be settled in the future with employees who meet eligibility requirements, uncertainties exist in estimating the timing and amount of future payments, and significant estimates are required to calculate pension expense and liabilities relating to these plans. The company utilizes the services of
65

TABLE OF CONTENTS
independent actuaries, whose models are used to help facilitate these calculations. Several key assumptions are used in actuarial models to calculate pension expense and liability amounts recorded in the financial statements; the most significant variables in the models are the expected rate of return on plan assets, the discount rate, and the expected rate of compensation increase. Management believes the assumptions used in the actuarial calculations are reasonable, reflect the company’s experience and expectations for the future and are within accepted practices in each of the respective geographic locations in which it operates. However, actual results in any given year often differ from actuarial assumptions due to economic events and different rates of retirement, mortality, and turnover. Refer to Notes 2 and 23 to the consolidated financial statements for a summary of the plan assumptions and additional information on our pension arrangements.
Expected Return on Plan Assets — In forming the assumption of the long-term rate of return on plan assets, we consider the expected earnings on funds already invested, earnings on contributions expected to be made in the current year, and earnings on reinvested returns. The long-term rate of return estimation methodology for the plans is based on a capital asset pricing model using historical data and a forecasted earnings model. An expected return on plan assets analysis is performed which incorporates the current portfolio allocation, historical asset-class returns, and an assessment of expected future performance using asset-class risk factors. A 100 basis point change in these expected long-term rates of return, with all other variables held constant, would change our pension expense by approximately $2 million.
Discount Rate — The discount rates selected for estimation of the actuarial present value of the benefit obligations are determined based on the prevailing market rate for high-quality, fixed-income debt instruments with maturities corresponding to the expected timing of benefit payments as of the annual measurement date for each of the various plans. These rates change from year to year based on market conditions that affect corporate bond yields. A 100 basis points change in discount rates, with all other variables held constant, would have a less than $1 million impact to our pension expense. A 100 basis points reduction in discount rates would increase the PBO by approximately $19 million whereas a 100 basis point increase in discount rates would decrease the PBO by approximately $17 million.
Rates of Compensation Increase - We determine these rates based on review of the underlying long-term salary increase trend characteristic of the local labor markets and historical experience, as well as comparison to peer companies. A 100 basis points change in the expected rate of compensation increase, with all other variables held constant, would change our pension expense by approximately $1 million. A 100 basis points reduction or increase in rate of compensation would change the PBO by approximately $5 million.
Recent Accounting Pronouncements
See Note 2 of notes to 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.
Refer to Item 3. Legal Proceedings for further information.
Item 7A. 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
66

TABLE OF CONTENTS
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 TiO 2 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, 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 TiO 2, 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 relatively low. 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 2025, 2024 and 2023 our ten largest third-party customers represented 36%, 37%, and 39%, respectively, of our consolidated net sales. During 2025, 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 2024 Term Loan Facility, the 2024-B Term Loan Facility, the RMB Term Loan Facility, the Cash Flow Revolver, the RMB Revolving Credit Facility and the Emirates Revolver balances. Using a sensitivity analysis as of December 31, 2025, 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 interest earning financial assets of $35 million at December 31, 2025 would increase by the full 1%, offsetting the impact of a 1% increase in interest expense on our floating rate debt of $748 million.
During 2019, we entered into interest-rate swap agreements for a portion of our previous Term Loan Facility, which effectively convert the variable rate to a fixed rate for a portion of the loan. The agreements were to expire in September 2024.
On March 27, 2023, the Company entered into amendments with two of our existing interest rate swap agreements with the
counterparty banks. As a result of these amendments, the Company terminated two of our existing interest rate swap contracts which were indexed to LIBOR with an aggregate notional value of $500 million which had maturity dates of September 2024. At the time of these amendments, the Company determined that the interest payments hedged are still probable to occur, therefore, the gains accumulated of $11 million on the interest rate swaps prior to the amendments are being amortized into interest expense through September 22, 2024, the original maturity of the interest rate swap agreements.
We simultaneously entered into two SOFR-indexed forward starting interest rate swaps with the same counterparty banks
with no change to the aggregate notional value. The forward starting swaps became effective from June 2023 and will mature
in March 2028 which will align with the maturity date of the Term Loan Facility. Indexing forward starting swaps to SOFR
will also ensure that the reference rates in our hedge instruments will align with the interest rate terms of the Term Loan
Facility which changed from LIBOR to SOFR effective June 30, 2023 as a result of Reference Rate Reform
and pursuant to the loan agreement. We elected to apply the hedge accounting expedients in ASC Topic 848, Reference Rate
Reform on Financial Reporting related to the following: 1) the assertion that the future forecasted transaction is still probable
of occurring despite reference rate changes and 2) the assumption that the index of the future hedged transactions will match
the index of the corresponding hedge instruments for the assessment of effectiveness.
Additionally, on March 27, 2023, the Company entered into a new interest rate swap with a $200 million notional value
which matures in March 2028 and effectively converts the variable rate to a fixed rate for that portion of the 2022 Term Loan
Facility.
On May 17, 2023, the Company entered into an agreement with the counterparty bank to amend the remaining $250 million
notional of the three original interest rate swap contracts of $750 million aggregate notional value. As a result of this
amendment, the Company changed the rate indexed in the contract from LIBOR to SOFR, effective June 30, 2023 as a result of the Reference Rate Reform and to align the index rate in this contract to that in the Term Loan Facility, as
67

TABLE OF CONTENTS
described above. This amendment did not change the notional value and the expiration date of this contract, which expired in September 2024. We completed a hedge effectiveness test as a result of this amendment and determined that this
hedge instrument continues to be highly effective, enabling us to continue to apply hedge accounting over the remaining term
of this hedge relationship.
As a result of the 2024 Amendment (discussed in Note 15), the Company noted that the hedged transaction associated with the interest rate swap with a notional value of $200 million (which converted the variable rate to a fixed rate for a portion of the 2022 Term Loan Facility) had changed as the hedged transaction would now convert the variable rate to a fixed rate for a portion of the 2024 Term Loan Facility. There were no amendments to the terms of the $200 million interest rate swap, including the notional value, index rate, or expiration date as a result of the 2024 Amendment. However, given the change in the hedged transaction, we completed a hedge effectiveness test and determined that this hedge instrument continues to be highly effective at achieving offsetting cash flows related to the hedged transaction, enabling us to continue to apply hedge accounting over the remaining term of this hedge relationship.
In line with the original maturity date, one of the interest rate swap agreements (notional value of $250 million) expired in September 2024. As a result of this, on September 26, 2024, the Company entered into two new interest-rate swap agreements for a notional of $125 million each with two counterparty banks, for an aggregate notional of $250 million. These new agreements are effective as of September 30, 2024 and will mature on September 30, 2031, in line with the maturity date of the 2024-B Term Loan Facility following Amendment No.6 (discussed in Note 15). The Company has designated these two new hedges as cash flow hedges with the objective of ensuring that the Company continues to achieve the offsetting effect to the interest rate volatility associated with the $250 million portion of the 2024-B Term Loan Facility.
Additionally, on September 26, 2024, the counterparty bank associated with one of the existing interest rate swap contracts (notional value of $250 million) novated its rights and obligations in the interest rate swap contracts to a new counterparty. No other terms and conditions of the interest rate swap contract were impacted by this transaction. We also determined that it is probable the new counterparty will perform its obligations under the interest rate swap agreements. However, following the novation, the Company terminated the existing interest rate swap agreement and simultaneously entered into a new interest rate swap agreement with the new counterparty bank with an effective date of September 30, 2024 and expiring on September 30, 2031 (in line with the maturity date of the 2024-B Term Loan Facility). At the time of this change, the Company determined that the interest payments hedged are still probable to occur, therefore, the gains accumulated of $3 million on the previous interest rate swap are being amortized into interest expense through March 11, 2028, the original maturity of the previous term loan agreement. As a result of this transaction, we completed a hedge effectiveness test and determined that this hedge instrument is highly effective at achieving offsetting cash flows related to the hedged transaction, enabling us to apply hedge accounting over the term of the new hedge relationship.
As of December 31, 2025, the Company maintains a total of $950 million of interest rate swaps (with $450 million maturing in March 2028 and $500 million maturing in September 2031) 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.
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. A significant portion of our Adjusted EBITDA is derived from jurisdictions that are subject to currency risk with Australia, Europe and South Africa representing the largest contributors. 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, France and the United Kingdom. The exposure is more 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.
We periodically enter into foreign currency contracts used to hedge non-functional currency sales for our South African subsidiaries and forecasted non-functional currency cost of goods sold and forecasted non-functional currency selling, general and

administrative expenses for our Australian subsidiaries. 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 income (loss) to the extent such contracts are effective, and are recognized in net sales or costs of goods sold in the period in which the forecasted transaction affects earnings or the transactions are no longer probable of occurring. As of December 31, 2025, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales and SG&A expenses to fluctuations in currency rates and we had no outstanding amounts to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates.
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 Consolidated Statements 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 December 31, 2025, there was (i) 572 million South African Rand (or approximately $35 million at the December 31, 2025 exchange rate), (ii) 161 million Australian dollars (or approximately $108 million at the December 31, 2025 exchange rate), (iii) 213 million Pound Sterling (or approximately $286 million at the December 31, 2025 exchange rate, (iv) 50 million Euro (or approximately $59 million at the December 31, 2025 exchange rate) and (v) 83 million Saudi Riyal (or approximately $22 million at the December 31, 2025 exchange rate) of notional amount of outstanding foreign currency contracts.

Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Tronox Holdings plc and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of operations, of comprehensive (loss) income, of changes in shareholders' equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
71

TABLE OF CONTENTS
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Realizability of Deferred Tax Assets
As described in Notes 2 and 6 to the consolidated financial statements, as of December 31, 2025, the Company has $975 million of net deferred tax assets, inclusive of valuation allowances associated with deferred tax assets of $2,040 million. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. Management periodically assesses the likelihood that the Company will be able to recover the deferred tax assets and reflects any changes in estimates in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income (loss), as appropriate. All available positive and negative evidence is weighed to determine whether a valuation allowance should be recorded.
The principal considerations for our determination that performing procedures relating to the realizability of deferred tax assets is a critical audit matter are the (i) significant judgment by management in determining whether deferred tax assets by jurisdiction are more likely than not to be realized in the future and (ii) a high degree of auditor judgment and effort in performing procedures relating to management’s assessment of the realizability of deferred tax assets.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the realizability of deferred tax assets. These procedures also included, among others (i) evaluating the positive and negative evidence available to support management’s assessment of the realizability of deferred tax assets; (ii) testing the completeness and accuracy of underlying data used by management; and (iii) evaluating management’s assessment of the realizability of deferred tax assets by jurisdiction. Evaluating management’s assessment of the realizability of deferred tax assets by jurisdiction involved considering (i) management’s assumptions relating to the assessment of cumulative tax losses by jurisdiction and (ii) management’s assessment of factors that may limit the realizability of deferred tax assets.

TRONOX HOLDINGS PLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(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 TiO 2 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 TiO 2 at our seven pigment facilities located in the United States, Australia, Brazil, UK, France 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 TiO 2 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
We are considered a domestic company in the United Kingdom and, as such, are required to comply with filing requirements in the United Kingdom. Additionally, we are not considered a “foreign private issuer” in the U.S.; therefore, we are required to comply with the reporting and other requirements imposed by the U.S. securities law on U.S. domestic issuers, which, among other things, requires reporting under accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements included in this Form 10-K are prepared in conformity with U.S. GAAP.
Our 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.
Use of Estimates
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.
2. Significant Accounting Policies
Foreign Currency
The U.S. dollar is our reporting currency for our consolidated financial statements in U.S. GAAP. We determine the functional currency of each subsidiary based on a number of factors, including the predominant currency for revenues, expenditures and borrowings. Adjustments from the remeasurement of non-functional currency monetary assets and liabilities are recorded in “Other expense (income), net” in the Consolidated Statements of Operations. When a subsidiary’s functional currency is not the U.S. dollar, translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are recorded in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets.
Translation adjustments on intercompany foreign currency receivables and payables that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments.
Revenue Recognition
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. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as “Net sales” in the Consolidated Statements of Operations. Accruals are made for sales returns, rebates and other allowances, which are recorded in “Net sales” in the Consolidated Statements of Operations and are based on our historical experience and current business conditions. Additionally, we have elected the practical

TABLE OF CONTENTS
expedient to exclude sales taxes and similar taxes that we collect from customers on behalf of government authorities from the revenue transaction price. See Note 4.
Cost of Goods Sold
Cost of goods sold includes costs for purchasing, receiving, manufacturing, and distributing products, including raw materials, energy, labor, depreciation, depletion, shipping and handling, freight, warehousing, and other production costs.
Research and Development
Research and development costs, included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations comprised of salaries, building costs, utilities, administrative expenses, third party research, and allocations of corporate costs, were $15 million, $14 million, and $12 million during 2025, 2024, and 2023, respectively, and were expensed as incurred.
Selling, General and Administrative Expenses
Selling, general and administrative expenses include costs related to marketing, research and development, agent commissions, and legal and administrative functions such as corporate management, human resources, information technology, investor relations, accounting, treasury, and tax compliance.
Income Taxes
We use the asset and liability method of accounting for income taxes. The estimation of the amounts of income taxes involves the interpretation of complex tax laws and regulations and how foreign taxes affect domestic taxes, as well as the analysis of the realizability of deferred tax assets, tax audit findings, and uncertain tax positions.
Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes in our estimates in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income (loss), as appropriate. All available positive and negative evidence is weighed to determine whether a valuation allowance should be recorded.
The amount of income taxes we pay is subject to ongoing audits by federal, state, and foreign tax authorities, which may result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We assess our income tax positions, and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, we record the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties are accrued as part of tax expense, where applicable. If we do not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. See Note 6.
Fair Value Measurement
We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows:
•Level 1 – Quoted prices in active markets for identical assets and liabilities;
•Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and,
•Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities
See Note 17.

TABLE OF CONTENTS
Cash and Cash Equivalents
We consider all investments with original maturities of three months or less to be cash equivalents. 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 generally 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.
At December 31, 2025 and December 31, 2024, we had restricted cash of approximately $12 million and $1 million, respectively. The amount at December 31, 2025 is primarily in the United States related to the annual payment associated with the sale of the Hawkins Point Plant. See Note 20 for further details. The amount at December 31, 2024 was in South Africa related to a profit-sharing arrangement as well as in Australia related to outstanding performance bonds.
Accounts Receivable, net of allowance for credit losses
We perform credit evaluations of our customers, and take actions deemed appropriate to mitigate credit risk. Only in certain specific occasions do we require collateral in the form of bank or parent company guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions.
Inventories, net
Pigment inventories are stated at the lower of actual cost and net realizable value, net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method. Carrying values include material costs, labor, and associated indirect manufacturing expenses. Costs for materials and supplies, excluding titanium ore, are determined by average cost to acquire. Feedstock and co-products inventories including titanium ore are stated at the lower of the weighted-average cost of production or market. Inventory costs include those costs directly attributable to products, including all manufacturing overhead but excluding distribution costs. Raw materials are carried at actual cost.
We review the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence. In either case, we record any write-down equal to the difference between the cost of inventory and its estimated net realizable value based on assumptions about alternative uses, market conditions and other factors. Inventories expected to be sold or consumed within twelve months after the balance sheet date are classified as current assets and all other inventories are classified as non-current assets. See Note 10.
Long Lived Assets
Property, plant and equipment, net is stated at cost less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows:

Land improvements | 10 — 20 years
Buildings | 10 — 40 years
Machinery and equipment | 2 — 25 years
Furniture and fixtures | 10 years

Maintenance and repairs are expensed as incurred, except for costs of replacements or renewals that improve or extend the lives of existing properties, which are capitalized. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is included in “Cost of goods sold” or “Selling, general, and administrative expenses” in the Consolidated Statements of Operations. See Note 11.
We capitalize costs associated with our asset retirement obligations which are generally included in machinery and equipment. See Note 19.
We capitalize interest costs on major projects that require an extended period of time to complete. See Note 15.
Mineral property acquisition costs are capitalized as tangible assets when management determines that probable future benefits consisting of a contribution to future cash inflows have been identified and adequate financial resources are available or are expected to be available as required to meet the terms of property acquisition and anticipated exploration and development expenditures. Mineral leaseholds are depleted over their useful lives as determined under the units of production method. Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves, the costs incurred to develop such property through the commencement of production are capitalized. See Note 12.

TABLE OF CONTENTS
Intangible assets are stated at cost less accumulated amortization and are amortized on a straight-line basis over their estimated useful lives, which generally range from 3 to 20 years. See Note 13.
We evaluate the recoverability of the carrying value of long-lived assets that are held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Under such circumstances, we assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are not sufficient, we calculate the impairment amount by discounting the projected cash flows using our weighted-average cost of capital. For assets that satisfy the criteria to be classified as held for sale, an impairment loss, if any, is recognized to the extent the carrying amount exceeds fair value, less cost to sell. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined.
Leases
We determine if a contract is or contains a lease at inception of the contract. Our leases are primarily operating leases. Leased assets primarily include office buildings, rail cars and motor vehicles, forklifts, and other machinery and equipment. Our leases primarily have fixed lease payments, with real estate leases typically requiring additional payments for real estate taxes and occupancy-related costs. Certain of our leases also have variable lease payments. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index) are included in our initial measurement of the lease right of use assets and lease liabilities. Variable lease payments that are not index or rate based (such as variable payments based on our performance or use of the leased assets) are recorded as expenses when incurred and excluded from the measurement of right of use assets and lease liabilities. Our leases typically have initial lease terms ranging from 1 to 25 years. Some of our lease agreements include options to renew, extend or early terminate the leases. Lease term is the non-cancellable period of a lease, adjusted by the period covered by an option to extend or terminate the lease if we are reasonably certain to exercise (or not exercise) that option. Our operating leases typically do not contain purchase options we expect to exercise, residual value guarantees or other material covenants.
Operating leases are recorded under “Lease right of use assets”, “Short-term lease liabilities”, and “Long-term lease liabilities” on the Consolidated Balance Sheets. Finance leases are recorded under “Property, plant and equipment net”, “Long-term debt due within one year”, and “Long-term debt” on the Consolidated Balance Sheets. Operating lease right of use ("ROU") assets and lease liabilities are initially recorded at the present value of the future minimum lease payments over the lease term at the commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future payments. Lease payments for the initial measurement of lease ROU assets and lease liabilities include fixed payments and variable payments that depend on an index or a rate. Variable lease payments that are not index or rate based are recorded as expenses when incurred. Operating lease ROU assets are amortized on a straight-line basis over the period of the lease. Finance lease assets are amortized on a straight-line basis over the shorter of their estimated useful lives and the lease terms. See Note 18.
Long-term Debt
Long-term debt is stated net of unamortized original issue premium or discount. Premiums or discounts are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Operations. Deferred debt issuance costs related to a recognized debt liability are presented in the Consolidated Balance Sheets as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Operations. See Note 15.
Asset Retirement Obligations
Asset retirement obligations are recorded at their estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Fair value is measured using expected future cash outflows discounted at our credit-adjusted risk-free interest rate, which are considered Level 3 inputs. We classify accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” in the Consolidated Statements of Operations. See Note 19.
Environmental Remediation and Other Contingencies
We record an undiscounted liability when any of the following occur: 1) a claim or assessment has been asserted, 2) a litigation has commenced, or 3) based on available information, it is probable that a claim or an assessment will be asserted or a litigation will commence; and in addition, the outcome is expected to be unfavorable to us and the associated costs can be reasonably estimated. See Note 20.

TABLE OF CONTENTS
Self-Insurance
We are self-insured for certain levels of general and vehicle liability, property, workers’ compensation and health care coverage. The cost of these self-insurance programs is accrued based upon estimated fully developed settlements for known and anticipated claims. Any resulting adjustments to previously recorded reserves are reflected in current operating results. We do not accrue for general or unspecific business risks.
Share-based Compensation
Equity Restricted Share and Restricted Share Unit Awards — The fair value of equity instruments is measured based on the share price on the grant date and is recognized over the vesting period. These awards contain service, market, and/or performance conditions. For awards containing only a service or a market condition, we have elected to recognize compensation costs using the straight-line method over the requisite service period for the entire award. For awards containing a market condition, the fair value of the award is measured using the Monte Carlo simulation under a lattice model approach. For awards containing a performance condition, the fair value is the grant date close price and compensation expense is not recognized until we conclude that it is probable that the performance condition will be met. We reassess the probability at least quarterly. See Note 22.
Defined Benefit Pension and Postretirement Benefit Plans
We recognize the funded status of our defined benefit pension plans and postretirement benefit plans in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. The benefit obligation for the defined benefit plans is the projected benefit obligation (PBO), which represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The benefit obligation for our postretirement benefit plans is the accumulated postretirement benefit obligation (APBO), which represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets related to our defined benefit plan represents the current market value of assets held in a trust fund, which is established for the sole benefit of plan participants.
If the fair value of plan assets exceeds the benefit obligation, the plan is overfunded, and the excess is recorded as a prepaid pension asset. On the other hand, if the benefit obligation exceeds the fair value of plan assets, the plan is underfunded, and the deficit is recorded as pension and postretirement healthcare benefits obligation in the Consolidated Balance Sheet. The portion of the pension and postretirement healthcare obligations payable within the next 12 months is recorded in accrued liabilities in the Consolidated Balance Sheet.
Net periodic pension and postretirement benefit cost represents the aggregation of service cost, interest cost, expected return on plan assets, amortization of prior service costs or credits and actuarial gains or losses previously recognized as a component of OCI and it is recorded in the Consolidated Statements of Operations. The service cost component of the net periodic service cost component is recorded in cost of goods sold and selling, general and administrative expenses in the Consolidated Statements of Operations based on the employees’ respective functions. The remaining portion of the net periodic cost related to interest cost, expected return in plan assets, amortization of prior service costs or credits, and actuarial gains or losses is recorded in Other expense (income), net in the Consolidated Statement of Operations.
Actuarial gains or losses represents the effect of remeasurement on the benefit obligation principally driven by changes in the plan actuarial assumptions. Prior service costs or credits arise from plan amendments. The actuarial gains or losses and prior service costs or credits are initially recognized as a component of Other comprehensive income (loss) in the Consolidated Statement of Comprehensive Income. Those gains or losses and prior service costs or credits are subsequently recognized as a component of net periodic cost.
The measurement of benefit obligations and net periodic cost is based on estimates and assumptions approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates.
Defined Contribution Plans — We recognize our contribution as expense when they are due. The expense is recorded in cost of goods sold or selling, general and administrative expenses the Consolidated Statements of Operations based on the employees’ respective functions.
Multiemployer Plan — We treat our multiemployer plan like a defined contribution plan. A pension plan to which two or more unrelated employers contribute is generally considered to be a multiemployer plan. As a defined contribution plan, we recognize the contribution for the period as a net benefit cost and any contributions due and unpaid as a liability.

TABLE OF CONTENTS
In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in this update apply to all public business entities. The standard requires that at each interim and annual reporting period an entity disclose additional information about specific expense categories in commonly presented expense captions within the notes to the financial statements. Further the amendments require that an entity include certain amounts that are already required to be disclosed by current GAAP in the same disclosure as the other disaggregation requirements, disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and disclose the total amount of selling expenses and an entity's definition of selling expenses (in annual reporting periods). The amendments in this update are effective for annual period beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. The guidance should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this update or (2) retrospectively to any or all prior periods presented in the financial statement. We are currently evaluating the impact this standard will have on our financial statements.
In September 2025, the FASB issued ASU 2025-06 “Intangibles-Goodwill and other-Internal-use Software (Subtopic 350-40)”. The amendments in this update apply to 1) all entities subject to the internal-use software guidance in Subtopic 350-40 and 2) those that account for website development costs in accordance with Subtopic 350-50. The amendments in this update seek to address previous application challenges by removing all references to the current prescriptive guidance and requiring an entity to start capitalizing software costs when both of the following occur: (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended, referred to as the “probable-to-complete recognition threshold”. The amendments also specify that the disclosure requirements in Subtopic 360-10, Property, Plant and Equipment-Overall, are required for all capitalized internal-use software costs, regardless of how those costs are presented in the financial statements. The amendments in this update are effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. We are currently evaluating the impact this standard will have on our financial statements.
Recently Adopted Accounting Pronouncements
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 adopted this standard as of December 31, 2025. Refer to Note 6 for further details.

(1) Represents severance that is statutorily required by law as well as any incremental enhancements that are provided by the respective actions.
(2) Represents decommissioning and idling activities and are expensed as incurred.
(3) Represents asset write-offs and accelerated depreciation.
Botlek closure
In March 2025, Tronox announced that it informed its Netherlands' labor force that it proposed to idle its 90,000 metric ton per year TiO 2 plant in the Netherlands indefinitely, as a result of a strategic review it undertook of the Company's global asset footprint. The Company believed this decision would optimize its global production footprint and improve its capacity utilizations. Approximately 240 employees were impacted by the action. As a result of this decision, the Company expects to record total restructuring and other related charges of approximately $180 million, approximately $75 million of which is
83

TABLE OF CONTENTS
expected to be related to non-cash items, arising from idling site operations which is currently expected to be completed in the first half of 2026.
For the year ended December 31, 2025, Tronox incurred $173 million of charges, of which $71 million were non-cash. These charges included $27 million in severance and employee separation benefits charges, $54 million for activities associated with idling of site operations, $11 million associated with asset retirement obligation adjustments, and $10 million of contract early termination charges. Tronox expects to incur incremental expenses associated with these items through the first half of 2026 as severance and employee benefit obligations become due, site idling activities occur and contracts are terminated.
In addition, the Company has recorded a non-cash charge of $71 million during the year ended December 31, 2025, primarily associated with asset write-downs and accelerated depreciation associated with assets which are not redeployable to other locations of the Company. Assets at the site will continue to be evaluated for redeployment to other locations throughout the idling process which could result in changes to the amount of asset write-downs and accelerated depreciation.
Fuzhou closure
Subsequent to the Botlek plant closure, the Company continued to review its global pigment plant portfolio and ultimately in January 2026, announced its permanent closure of its 46,000 metric ton per year TiO 2 plant in Fuzhou, China. The closure reflects ongoing weak Chinese domestic demand and increasing costs plus continued excess Chinese TiO 2 production. This action was a result of a strategic review it undertook of the Company's global asset footprint. The Company believes this decision will optimize its global production footprint and improve its capacity utilizations. This action is expected to impact approximately 550 employees located at the site. As a result of this decision, the Company expects to record total restructuring and other related charges of approximately $60-80 million, $35-45 million of which is expected to be related to non-cash items, arising from idling site operations which is currently expected to be completed in 2026.
For the year ended December 31, 2025, Tronox incurred $59 million of charges, of which $38 million were non-cash related to the Fuzhou closure. These charges included $10 million in severance and employee separation benefits charges, $8 million associated with environmental obligation adjustments and $2 million of contract early termination charges. Tronox expects to incur incremental expenses associated with these items through the end of 2026 as severance and employee benefit obligations become due, site idling activities occur and contracts are terminated.
In addition, the Company has recorded a non-cash charge of $38 million during the year ended December 31, 2025, primarily associated with asset write-downs and accelerated depreciation associated with assets which are not redeployable to other locations of the Company.
Rollforward of restructuring and other charges reserve
The following table shows a rollforward of restructuring and other charges reserves that will result in cash spending. These amounts exclude asset retirement obligations and environmental liability, which are included in "Asset retirement obligations" and "Environmental liabilities", respectively, on the Consolidated Balance Sheets:

| Balance at January 1, 2025 |  | Changes in Reserves |  | Cash Payments |  | Foreign currency translation and other |  | Balance at December 31, 2025
Botlek closure | $ | — |  |  | $ | 91 |  |  | $ | (76) |  |  | $ | 1 |  |  | $ | 16 |
Fuzhou closure | — |  |  | 12 |  |  | — |  |  | — |  |  | 12 |
Total | $ | — |  |  | $ | 103 |  |  | $ | (76) |  |  | $ | 1 |  |  | $ | 28 |

Cash payments associated with the liability at December 31, 2025 for the Netherlands are expected to occur through the second quarter of 2026 and primarily through December 31, 2026, for Fuzhou. As of December 31, 2025, $23 million and $5 million are recorded within "Accrued liabilities" and "Other long-term liabilities", respectively, on the Consolidated Balance Sheet.
4. Revenue
Nature of Contracts and Performance Obligations
84

TABLE OF CONTENTS
We primarily generate revenue from selling TiO 2 pigment products and related co-products, primarily zircon and pig iron, to our customers. These products are used for the manufacture of paints, coatings, plastics, paper, and a wide range of other applications. We account for a contract with our customer when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable.
Our promise in a contract typically relates to the transferring of a product or multiple distinct products that are substantially the same and that have the same pattern of transfer, representing a single performance obligation within a contract. We have elected to account for shipping and handling activities that occur after control of the products has transferred to the customer as contract fulfillment activities, rather than a separate performance obligation. Amounts billed to a customer in a sales transaction related to shipping and handling activities continue to be reported as “Net sales” and related costs as “Cost of goods sold” in the Consolidated Statements of Operations.
The duration of our contract period is one year or less. As such, we have elected to recognize incremental costs incurred to obtain contracts, which primarily consist of commissions paid to third-party sales agents, as “Selling, general and administrative expenses” in the Consolidated Statements of Operations. Furthermore, we have elected not to disclose the value of unsatisfied performance obligations at each period end, given the original expected duration of our contracts are one year or less.
Transaction Price
Revenue is measured as the amount of consideration that we expect to be entitled in exchange for transferring products to the customer. The transaction price typically consists of fixed cash consideration. We also offer various incentive programs to our customers, such as rebates, discounts, and other price adjustments that represent variable consideration. We estimate variable consideration and include such consideration amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We adjust our estimate of revenue at the earlier of when the amount of consideration we expect to receive changes or when the consideration becomes fixed. Sales returns rarely happen in our business; therefore, it is unlikely that a significant reversal of revenue will occur.
Sales and similar taxes we collect on behalf of governmental authorities are excluded from the transaction price for the determination of revenue. The expected costs associated with product warranties continue to be recognized as expense when the products are sold. Customer payment terms and conditions vary by contract and customer, although the timing of revenue recognition typically does not differ from the timing of invoicing. Additionally, as we generally do not grant extended payment terms, we have determined that our contracts generally do not include a significant financing component.
Revenue Recognition
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 Balances
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. As of December 31, 2025, and December 31, 2024, we did not have material contract asset balances.
Contract liabilities represent our obligations to transfer products to a customer for which we have received consideration from the customer. When a customer has poor credit worthiness, we may receive advance payment 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 December 31, 2025 and December 31, 2024 were $4 million and less than $1 million, respectively. Contract liability balances were reported as “Accrued liabilities” in the Consolidated Balance Sheets. All material contract liabilities as of December 31, 2024 and 2023 were recognized as revenue in “Net sales” in the Consolidated Statements of Operations during the first quarter of 2025 and first quarter of 2024, respectively.
Disaggregation of Revenue
85

TABLE OF CONTENTS
We operate under one operating and reportable segment, Tronox. See Note 25 for details. 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:

| Year Ended December 31,
2025 |  | 2024 |  | 2023
North America | $ | 749 |  |  | $ | 796 |  |  | $ | 754 |
South and Central America | 193 |  |  | 208 |  |  | 159 |
Europe, Middle-East and Africa | 1,166 |  |  | 1,191 |  |  | 1,131 |
Asia Pacific | 790 |  |  | 879 |  |  | 806 |
Total net sales | $ | 2,898 |  |  | $ | 3,074 |  |  | $ | 2,850 |

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

| Year Ended December 31,
2025 |  | 2024 |  | 2023
TiO 2 | $ | 2,298 |  |  | $ | 2,407 |  |  | $ | 2,248 |

Total net sales | $ | 2,898 |  |  | $ | 3,074 |  |  | $ | 2,850 |

Other products mainly include pig iron, TiCl 4 and other mining products. The nature, amount, timing and uncertainty of revenue and cash flows typically do not differ significantly among different products.

Tronox Holdings plc is a U.K. public limited company and the parent company for the business group. The statutory tax rate in the U.K. was 25% at December 31, 2025, 2024 and 2023. The statutory rate in the U.K. changed to 25% effective April 1, 2023 and a weighted average rate of 23.5% was applied for the full year 2023.
The effective tax rates in 2025, 2024 and 2023 are all influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, non-taxable income and expenses, withholding taxes, prior year accruals, and rates different than the United Kingdom statutory rate. The valuation allowances in each year were impacted by items other than

income and losses as follows: 2024 was impacted by recording valuation allowances in Brazil and the Netherlands and 2023 was impacted by recording valuation allowances in China and Australia.

The net deferred tax assets reflected in the above table include deferred tax assets related to grantor trusts, which were established as Tronox Incorporated emerged from bankruptcy during 2011. The balances relate to the assets contributed to such grantor trusts by Tronox Incorporated and the proceeds from the resolution of previous litigation of $5.2 billion during 2014, which resulted in additional deferred tax assets of $2.0 billion. As the grantor trusts continue to spend funds received from the litigation and earn income from the investment of those funds, the U.S. net operating loss will increase or decrease.
There was an increase to our valuation allowance of $89 million and $91 million during 2025 and 2024, respectively. The table below sets forth the changes, by jurisdiction:

| December 31,
| 2025 |  | 2024
United Kingdom | $ | 11 |  |  | $ | 5 |

Total increase in valuation allowances | $ | 89 |  |  | $ | 91 |

During the year ended December 31, 2024, we identified negative evidence concerning our ability to realize our deferred tax assets in Brazil and the Netherlands. This evidence primarily relates to operational losses generated during the year, a three-year cumulative loss threshold crossed during the year, and fluctuating levels of income and expenses which have led to uncertainty regarding the ability to generate net income in these regions for the foreseeable future. After weighing all the positive and
89

TABLE OF CONTENTS
negative evidence, we determined it is more likely than not that Brazil and the Netherlands deferred tax assets may not be realized. As a result, we recorded non-cash charges of $16 million and $33 million to tax expense for Brazil and the Netherlands, respectively.
At December 31, 2025, we continue to maintain full valuation allowances related to the total net deferred tax assets in Australia, Brazil, the Netherlands and the United Kingdom, as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. Future provisions for income taxes in these jurisdictions will include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments until the valuation allowances are eliminated. Additionally, we have valuation allowances against specific tax assets in China, South Africa and the U.S.
The deferred tax assets generated by tax loss carryforwards in Australia, Brazil, China, the Netherlands and the United Kingdom have been fully offset by valuation allowances. In the United States, the deferred tax assets generated by tax loss carryforwards are partially offset by a valuation allowance to the extent they are subject to expiration. The expiration of tax loss carryforwards at December 31, 2025 are shown below. The tax loss carryforwards in Australia, Brazil, France, Saudi Arabia, South Africa, the Netherlands and the United Kingdom do not expire.

At December 31, 2025, Tronox Holdings plc had foreign subsidiaries with undistributed earnings. Although we would not be subject to income tax on these earnings, amounts totaling $720 million are in specific jurisdictions which we assert are indefinitely reinvested outside of the parents' 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. The Company has removed its assertion that earnings in China are indefinitely reinvested, and the withholding tax accruals for potential repatriations from that jurisdiction are now reflected in the effective tax rate reconciliation above.
The noncurrent liabilities section of our Consolidated Balance Sheet does not reflect any reserves for uncertain tax positions for either 2025 or 2024.
Our Brazil, China, Netherlands and Saudi Arabia returns are closed through 2020; our South Africa, UK and U.S. returns are closed through 2021; and our France return is closed through 2022. During the year ended December 31, 2025, the Company received notification that the Australian Taxation Office ("ATO") initiated an audit of Tronox Limited, Tronox Holdings plc and their associates for the calendar years 2019 - 2022. As of the date hereof, the Company is continuing to respond to requests for information with respect to this audit.
We believe that we have made adequate provision for income taxes that may be payable with respect to years open for examination; however, the ultimate outcome is not presently known and, accordingly, additional provisions may be necessary and/or reclassifications of noncurrent tax liabilities to current may occur in the future.
The new U.S. tax law, officially titled the "One Big Beautiful Bill", was signed into law on July 4, 2025. It represents a significant update of tax policy and includes a wide range of provisions. Many of the policy updates do not have a material impact on our U.S. entities.

TABLE OF CONTENTS
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 Pillar Two, effective beginning in 2024. Additionally, various other jurisdictions have now implemented Domestic Minimum Taxes which are also effective beginning in 2024. Neither the UK Multinational Top-up Tax nor any jurisdiction's Domestic Minimum Tax have an impact on our income tax provisions for 2025.
The net amount of taxes paid and refunded is presented in the Consolidated Statement of Cash Flows. Detail for the income taxes paid by the Company by jurisdiction are as follows:

7. Loss Per Share
The computation of basic and diluted loss per share for the periods indicated is as follows:

| Year Ended December 31,
| 2025 |  | 2024 |  | 2023
Numerator – Basic and Diluted: |  |  |  |  |
Net loss | $ | (473) |  |  | $ | (54) |  |  | $ | (314) |
Less: Net (loss) income attributable to noncontrolling interest | (3) |  |  | (6) |  |  | 2 |
Net loss available to ordinary shares | $ | (470) |  |  | $ | (48) |  |  | $ | (316) |
Denominator – Basic and Diluted: |  |  |  |  |
Weighted-average ordinary shares, basic (in thousands) | 158,484 |  |  | 157,819 |  |  | 156,397 |
Weighted-average ordinary shares, diluted (in thousands) | 158,484 |  |  | 157,819 |  |  | 156,397 |
Net loss per Ordinary Share: |  |  |  |  |
Basic net loss per ordinary share | $ | (2.97) |  |  | $ | (0.31) |  |  | $ | (2.02) |
Diluted net loss per ordinary share | $ | (2.97) |  |  | $ | (0.31) |  |  | $ | (2.02) |

Net loss per ordinary share amounts were calculated from exact, unrounded net loss and share information. Anti-dilutive shares not recognized in the diluted net loss per share calculation for the years ended December 31, 2025, 2024 and 2023 were as follows:

| Shares
| 2025 |  | 2024 |  | 2023

Restricted share units | 5,039,873 |  |  | 1,997,987 |  |  | 2,475,125 |

8. Inventory Financing Arrangement
On July 29, 2025, we entered into an inventory financing arrangement whereby we agree with our counterparty to sell certain inventory, with short payment terms, and subsequently we repurchase such inventory at an agreed upon price with terms not to exceed 360 days. The agreed upon repurchase price is generally calculated as the original sale price plus financing charges and a nominal spread. As of December 31, 2025, we financed inventory of $50 million and we incurred $2 million of accrued interest, which were included in “Obligations under inventory financing arrangements” and “Accrued Liabilities”, respectively, on the
91

TABLE OF CONTENTS
Consolidated Balance Sheets. For the year ended December 31, 2025 we recorded $2 million of financing charges within “Interest Expense” on the Consolidated Statement of Operations.
In January 2026, we repaid in cash our payable due to the counterparty and shortly thereafter, we entered into a new inventory financing arrangement on terms similar to those referenced above. The amount financed in this new transaction remains at $50 million.
9. 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”). The purpose of this program is to enhance the Company's financial flexibility by providing
additional liquidity. The Securitization Facility permitted the SPE to sell accounts receivable up to $75 million (the “Facility
Limit”). Under the Securitization Facility, our wholly-owned U.S. operating subsidiary, Tronox LLC (“Originator”), sells its
entire accounts receivable on a periodic basis to the SPE. The SPE in turn sells undivided interests in the receivables that meet
certain eligibility criteria, pursuant to the terms of a receivable purchase agreement, to the Purchaser in exchange for cash, not to
exceed the Facility Limit. The SPE retains the remaining receivables as unsold receivables which are pledged as a collateral for
the sold receivables to which the purchaser is granted a first priority security interest.
Following the sale of the receivables by the Originator to the SPE, the receivables are legally isolated from Tronox and its affiliated entities, and upon the subsequent sale and transfer of the receivables from the SPE to the administrative agent, effective control of the receivables is passed to the purchaser, which has all rights, including the right to pledge or sell the receivables. Any new receivables that are not sold to the purchaser by the SPE are added to the unsold receivables held as collateral.
In November 2022, the Securitization Facility was amended (the "First Amendment") to include receivables generated by our 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 extended the program term to November 2025. Following this amendment, we sold additional accounts receivable in exchange for net cash proceeds of $72 million, for a total aggregate amount of $147 million for the combined program.
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. As a result of the Second Amendment, during the year ended December 31, 2023, we incurred $1 million of transaction costs, which are recorded in "Other expense (income), net" in our Consolidated Statement of Operations.
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.
In March 2025, the Securitization Facility was amended (the "Fifth Amendment") to extend the program term to March 2028.
As the Company does not maintain effective control over the sold receivables, we derecognize the sold receivables from our
Consolidated Balance Sheet and classify the cash proceeds as source of cash from operating activities in our 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. At December 31, 2025 and 2024, the total value of accounts receivable sold under the Securitization Facility and derecognized from the Company's Consolidated Balance Sheet was $230 million and $215 million, respectively. This resulted in the Company recording $15 million within "Accounts payable" on the Consolidated Balance Sheet at December 31, 2024 as this amount is due to the Purchaser as a result of a periodic decrease in accounts receivable sold to the Purchaser, which was paid in January 2025. There were no corresponding amounts at December 31, 2025. Additionally, at December 31, 2025 and 2024, respectively, we retained $133 million and $109 million of unsold receivables that 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:

Long-term Debt
2024 Term Loan Facility
On May 1, 2024, the Company, its indirect subsidiary, Tronox Finance LLC (the "Borrower") and certain of the Company’s subsidiaries, entered into Amendment No. 4 ("Amendment 4") to the senior secured first lien term loan credit facility dated as of March 11, 2021 (as amended through and including Amendment No. 4, the "Credit Agreement") with the term lenders party thereto and HSBC Bank USA, National Association, as Administrative Agent and Collateral Agent. Amendment 4 provided the Borrower with a five-year incremental term loan facility ("the 2024 Term Loan Facility") in an aggregate initial principal amount of $741 million. The 2024 Term Loan Facility was used to refinance in full the Company's then outstanding term loan facilities entered into in April 2022 and April 2023, respectively, pursuant to the Credit Agreement.
Subject to certain customary and other exceptions, the obligations of the Borrower under the 2024 Term Loan Facility are (a) guaranteed on a joint and several basis by the Company and certain of the Company's restricted subsidiaries, and (b) secured by a first priority lien on substantially all of the Borrower's and guarantors' assets, including inventory, receivables and related assets, and equipment, equity interests in subsidiaries, and material real property, in each case subject to certain limitations and principles. The 2024 Term Loan Facility is a separate class of loans under the Credit Agreement, and if the Borrower elects to make an optional payment under the Credit Agreement or is required to make a mandatory prepayment under the Credit Agreement, the Borrower may, in each case, select which class or classes of loans to prepay.
The 2024 Term Loan Facility amortizes in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount of the 2024 Term Loan Facility commencing with the second full fiscal quarter after the effective date of the 2024 Term Loan Facility. The final maturity of the 2024 Term Loan Facility will occur on April 4, 2029. The 2024 Term Loan Facility permits amendments thereto whereby individual lenders may extend the maturity date of their outstanding loans upon the Borrower's request without the consent of any other lender, so long as certain conditions are met. The 2024 Term Loan Facility shall bear interest, at the Borrower's option, at either the base rate or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the 2024 Term Loan Facility is 1.75% per annum for base rate loans or 2.75% per annum for SOFR rate loans.
The 2024 Term Loan Facility contains customary covenants that provide for certain restrictions with respect to, among other things and subject to certain limitations, thresholds and exceptions, the ability of the Company and its subsidiaries to: incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). The 2024 Term Loan Facility also contains customary representations and warranties, affirmative covenants and events of default. If an event of default occurs under the 2024 Term Loan Facility, then a majority of the lenders through the administrative agent, may (a) declare the 2024 Term Loan Facility (and all other loans) to be immediately due and payable and/or (b) foreclose on the collateral securing the obligations under the Credit Agreement.
On December 18, 2024, the Borrower, together with the Company and certain of the Company's subsidiaries, entered into Amendment No. 7 to the Credit Agreement (the "Repricing Amendment"). The Repricing Amendment amended the 2024 Term Loan Facility by (i) reducing the applicable rate per annum to 1.25% per annum for base rate loans or 2.25% per annum for SOFR rate loans and (ii) implementing certain mechanical and other related changes. As of December 31, 2025, the applicable margin under the 2024 Term Loan Facility was 2.25%. As of December 31, 2025 and 2024, the total outstanding principal balance was $736 million and $741 million, respectively, of which $7 million and $6 million, respectively, is recorded within "Long-term debt due within one year" on the Consolidated Balance Sheet.

2024-B Term Loan Facility
On September 30, 2024, the Borrower, together with the Company and certain of the Company's subsidiaries, entered into Amendment No. 6 to the Credit Agreement ("Amendment No. 6"). Amendment No. 6 provides the Borrower with a new seven-year incremental term loan facility (the "2024-B Term Loan Facility") in an aggregate principal amount of $902 million. The proceeds of the 2024-B Term Loan Facility was used to refinance in full all of the outstanding amounts of the then outstanding term loan facility entered into in March 2021 pursuant to the Credit Agreement.
The obligations of the Borrower under the 2024-B Term Loan Facility are guaranteed and secured by the same guarantees and liens under the Credit Agreement prior to the effectiveness of Amendment No. 6. The 2024-B Term Loan Facility is a separate class of loans under the Credit Agreement, and if the Borrower elects to make an optional payment under the Credit Agreement or is required to make a mandatory prepayment under the Credit Agreement, the Borrower may, in each case, select which class or classes of loans to prepay.
The 2024-B Term Loan Facility amortizes in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount of the 2024-B Term Loans. The final maturity of the 2024-B Term Loan Facility will occur on September 30, 2031. The 2024-B Refinancing Facility permits amendments thereto whereby individual lenders may extend the maturity date of their outstanding loans upon the Borrower’s request without the consent of any other lender, so long as certain conditions are met. The 2024-B Term Loans bears interest, at the Borrower’s option, at either the base rate or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the 2024-B Term Loan Facility is 1.5% per annum for base rate loans or 2.5% per annum for SOFR rate loans. Based on our first lien net leverage ratio pursuant to the credit agreement, the applicable margin under the 2024-B Term Loan Facility as of December 31, 2025 was 2.50%.
The 2024-B Term Loan Facility contains the same negative covenants applicable to the term loans outstanding under the Credit Agreement immediately prior to the effectiveness of Amendment No. 6, which covenants, subject to certain limitations, thresholds and exceptions, limit the Company and its restricted subsidiaries to (among other restrictions): incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). The 2024-B Term Loan Facility also contains the same representations and warranties, affirmative covenants and events of default applicable to the term loans outstanding under the Credit Agreement immediately prior to the effectiveness of Amendment No. 6. If an event of default occurs under the 2024-B Term Loan Facility, then a majority of the lenders through the administrative agent, may (a) declare the 2024-B Term Loan Facility (and all other loans) to be immediately due and payable and/or (b) foreclose on the collateral securing the obligations under the Credit Agreement.
As a result of this transaction, we recognized approximately $2 million in "Loss on extinguishment of debt" on the Consolidated Statement of Operations for the year ended December 31, 2024. As of December 31, 2025 and 2024, the total outstanding principal balance was $893 million and $902 million, respectively, of which $9 million is recorded within "Long-term debt due within one year" on the Consolidated Balance Sheet for both periods.

RMB Term Loan Facility and RMB Revolving Credit Facility
On August 16, 2024, Tronox Minerals Sands Proprietary Limited and Tronox KZN Sands Proprietary Limited, wholly- owned subsidiaries of the Company, entered into Amendment No. 2 (“the Amendment”) and restatement of a credit facility with RMB, that superseded and replaced the term loan facility and revolving credit facility with Standard Bank in their entirety. The amended credit facility provides the Company with (a) a new five-year term loan facility in an aggregate principal amount of R1.1 billion (approximately $66 million at the December 31, 2025 exchange rate) (the "RMB Term Loan Facility") and (b) a new three-year revolving credit facility (the "RMB Revolving Credit Facility") providing an increase of the revolving commitments of R1.2 billion (approximately $72 million at the December 31, 2025 exchange rate). The maturity date on the RMB Term Loan Facility and the RMB Revolving Credit Facility is August 16, 2029 and August 16, 2027, respectively. Mandatory capital repayments of R37.5 million (approximately $2 million at the December 31, 2025 exchange rate) are scheduled quarterly with the first mandatory repayment starting in March 31, 2025.
Both the RMB Term Loan Facility and RMB Revolving Credit Facility shall bear interest at an adjusted JIBAR rate plus an applicable margin. The applicable margin on the RMB Term Loan Facility is 2.35%. The applicable margin on the RMB Revolving Credit Facility is based upon average credit utilization during any interest period. If the revolving credit facility utilization is less than 33%, less than 66% but greater than 33%, or greater than 66%, the applicable margin is 1.95%, 2.10%, and 2.25%, respectively. The RMB Revolving Credit Facility requires the borrower to pay customary agency fees.
Australian Government Loan
We maintain an interest-free loan with the Australian government (“Australian Government Loan”) that is subject to renewal every 5 years and is contingent on renewal of our Australind site leases with final maturity in December 2036. The loan balance due upon maturity is AUD 6 million (approximately $4 million at the December 31, 2025 exchange rate). At December 31, 2025, the discounted value on the Australian Government Loan was approximately AUD 2 million (approximately $2 million at the December 31, 2025 exchange rate).
MGT Loan
On December 17, 2020, we completed our agreement with Cristal to acquire certain assets co-located at our Yanbu facility which produce metal grade TiCl4 (“MGT”) in exchange for a $36 million note payable. Repayment of the note payable is based on a fixed U.S. dollar per metric ton quantity of MGT delivered by us to Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd (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 will no longer owe any amount under the loan agreement with Cristal. We currently estimate the ultimate maturity to be between approximately five to six years, subject to actual future MGT production levels. The interest rate is based on the Saudi Arabian Interbank Offered Rate (“SAIBOR”) plus a premium. As of December 31, 2025, the outstanding balance of the note payable was $13 million, of which $8 million is expected to be paid within the next twelve months (recorded within "Long-term debt due within one year" on our Consolidated Balance Sheet). Refer to Note 24 for further information on the MGT transaction.

Amendment No. 5 provided for a $350 million replacement revolving loan facility (the "Cash Flow Revolver") which refinanced and replaced the Borrower's existing $350 million revolving loan facility under the Credit Agreement initially entered in March 2021. As a result of this transaction, we recorded less than $1 million in "Loss on extinguishment of debt" on the Consolidated Statement of Operations for the year ended December 31, 2024.
The obligations of the Borrower under the Cash Flow Revolver are guaranteed and secured by the same guarantees and liens under the Credit Agreement prior to the effective date of Amendment No. 5. The Cash Flow Revolver is a separate class of loans under the Credit Agreement.
The maturity date of the Cash Flow Revolver will occur on the earlier of (a) August 15, 2029 and (b) the Springing Maturity Date. The Springing Maturity Date is defined under the Credit Agreement as the earlier of the date that is 91 days prior to (i) the scheduled maturity date of the 2024 Term Loan Facility if on such date the outstanding amount of the term loans under the 2024 Term Loan Facility is greater than $200 million, (ii) the stated maturity date of the Senior Unsecured 2029 if on such date the aggregate outstanding principal amount of the Senior Unsecured 2029 Notes is greater than $200 million, and (iii) the stated maturity date of certain debt-for-borrowed money (excluding debt issued under the Borrower's inside maturity date basket and certain other debt baskets under the Credit Agreement) incurred after the date of Amendment No. 5 if on such date the aggregate outstanding principal amount of such debt-for-borrowed money is greater than $200 million.
The Cash Flow Revolver bears interest, at the Borrower's option, at either the base rate or the SOFR rate, in each case plus an applicable margin. The applicable margin in respect of the Cash Flow Revolver shall be determined based on the Borrower's first lien net leverage ratio as of the then most recently ended fiscal quarter and shall range from 1.25% to 0.75% per annum for base rate loans or 2.25% to 1.75% per annum for SOFR rate loans. As of December 31, 2025, the applicable margin on the Cash Flow Revolver was 2.25%.
The Cash Flow Revolver contains substantially the same negative covenants applicable to the previous cash flow revolving credit facility, which covenants, subject to certain limitations, thresholds and exceptions, limit the Company and its restricted subsidiaries to (among other restrictions): incur indebtedness; grant liens; pay dividends and make subsidiary and certain other distributions; sell assets; make investments; enter into transactions with affiliates; and make certain modifications to material documents (including organizational documents). The Cash Flow Revolver also contains substantially the same representations and warranties, affirmative covenants and events of default applicable to the previous cash flow revolving credit facility. If an event of default occurs under the Cash Flow Revolver, then a majority of the lenders acting through the administrative agent, may (a) declare loans under the Cash Flow Revolver (and all other loans) to be immediately due and payable and/or (b) foreclose on the collateral securing the obligations under the Credit Agreement.
In addition, the Credit Agreement contains a springing financial covenant solely for the benefit of the revolving lenders of the Cash Flow Revolver under the Credit Agreement. The springing financial covenant requires compliance with a maximum first lien net leverage ratio of not greater than 4.75x (measuring the ratio of Consolidated First Lien Debt to Consolidated EBITDA, each as defined in the Credit Agreement) if, on the last day of any fiscal quarter, revolving exposure (excluding undrawn or cash collateralized letters of credit) exceeds 35% of the aggregate principal amount of all revolving commitments under the Cash Flow Revolver.
Debt issuance costs associated with the Cash Flow Revolver of $2 million were included in “Other long-term assets” in the Consolidated Balance Sheets at both December 31, 2025 and 2024, and were amortized over the life of the Cash Flow Revolver.

Interest Rate Risk
During the second quarter of 2019, we entered into interest-rate swap agreements with an aggregate notional value of $750 million representing a portion of our Term Loan Facility, which effectively converted the variable rate to a fixed rate for that portion of the loan. The agreements were to expire in September 2024.
On March 27, 2023, the Company entered into amendments to two of our existing interest rate swap agreements with the counterparty banks. As a result of these amendments, the Company terminated two of our existing interest rate swap contracts which were indexed to LIBOR with an aggregate notional value of $500 million which had maturity dates of September 2024. At the time of these amendments, the Company determined that the interest payments hedged are still probable to occur, therefore, the gains accumulated of $11 million on the interest rate swaps prior to the amendments were being amortized into interest expense through September 22, 2024, the original maturity of the interest rate swap agreements.
We simultaneously entered into two SOFR-indexed forward starting interest rate swaps with the same counterparty banks with no change to the aggregate notional value. The forward starting swaps became effective in June 2023 and will mature in March 2028 which is aligned with the maturity date of the Term Loan Facility. Indexing forward starting swaps to SOFR also ensured that the reference rates in our hedge instruments are now aligned with the interest rate terms of the Term Loan Facility which also changed from LIBOR to SOFR in June 2023 as a result of Reference Rate Reform and pursuant to the loan agreement. We elected to apply the hedge accounting expedients in ASC Topic 848, Reference Rate Reform on Financial Reporting related to the following: 1) the assertion that the future forecasted transaction is still probable of occurring despite reference rate changes and 2) the assumption that the index of the future hedged transactions will match the index of the corresponding hedge instruments for the assessment of effectiveness.
Additionally, on March 27, 2023, the Company entered into a new interest rate swap with a $200 million notional value which matures in March 2028 and effectively converted the variable rate to a fixed rate for that portion of the 2022 Term Loan Facility.
On May 17, 2023, the Company entered into an agreement with the counterparty bank to amend the remaining $250 million notional of the three original interest rate swap contracts of $750 million aggregate notional value. As a result of this amendment, the Company changed the rate indexed in the contract from LIBOR to SOFR, effective June 30, 2023 as a result of the Reference Rate Reform and to align the index rate in this contract to that in the Term Loan Facility, as described above. This amendment did not change the notional value and the expiration date of this contract, which expired in September 2024. We completed a hedge effectiveness test as a result of this amendment and determined that this hedge instrument continues to be highly effective, enabling us to continue to apply hedge accounting over the remaining term of this hedge relationship.
102

TABLE OF CONTENTS
As a result of Amendment No. 4 (discussed in Note 15), the Company noted that the hedged transaction associated with the interest rate swap with a notional value of $200 million (which converted the variable rate to a fixed rate for a portion of the then outstanding term loan facility entered into in April 2022) had changed as the hedged transaction would now convert the variable rate to a fixed rate for a portion of the 2024 Term Loan Facility. There were no amendments to the terms of the $200 million interest rate swap, including the notional value, index rate, or expiration date as a result of the amendment. However, given the change in the hedged transaction, we completed a hedge effectiveness test and determined that this hedge instrument continues to be highly effective at achieving offsetting cash flows related to the hedged transaction, enabling us to continue to apply hedge accounting over the remaining term of this hedge relationship.
In line with the original maturity date, one of the interest rate swap agreements (notional value of $250 million) expired in September 2024. As a result of this, on September 26, 2024, the Company entered into two new interest-rate swap agreements for a notional of $125 million each with two counterparty banks, for an aggregate notional of $250 million. These new agreements are effective as of September 30, 2024 and will mature on September 30, 2031, in line with the maturity date of the 2024-B Term Loan Facility following Amendment No.6 (discussed in Note 15). The Company has designated these two new hedges as cash flow hedges with the objective of ensuring that the Company continues to achieve the offsetting effect to the interest rate volatility associated with the $250 million portion of the 2024-B Term Loan Facility.
Additionally, on September 26, 2024, the counterparty bank associated with one of the existing interest rate swap contracts (notional value of $250 million) novated its rights and obligations in the interest rate swap contracts to a new counterparty. No other terms and conditions of the interest rate swap contract were impacted by this transaction. We also determined that it is probable the new counterparty will perform its obligations under the interest rate swap agreements. However, following the novation, the Company terminated the existing interest rate swap agreement and simultaneously entered into a new interest rate swap agreement with the new counterparty bank with an effective date of September 30, 2024 and expiring on September 30, 2031 (in line with the maturity date of the 2024-B Term Loan Facility). At the time of this change, the Company determined that the interest payments hedged are still probable to occur, therefore, the gains accumulated of $3 million on the previous interest rate swap are being amortized into interest expense through March 11, 2028, the original maturity of the previous term loan agreement. As a result of this transaction, we completed a hedge effectiveness test and determined that this hedge instrument is highly effective at achieving offsetting cash flows related to the hedged transaction, enabling us to apply hedge accounting over the term of the new hedge relationship.
As of December 31, 2025, the Company maintains a total of $950 million of interest rate swaps (with $450 million maturing in March 2028 and $500 million maturing in September 2031) 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.
For the year ended December 31, 2025, 2024 and 2023, the amounts recorded in interest expense related to the interest-rate swap agreements were $8 million, $26 million and $26 million, respectively. At December 31, 2025 and December 31, 2024, the net unrealized loss was less than $1 million and the unrealized gain was $26 million, respectively, and was recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet.
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. From time to time, we enter into foreign currency contracts used to hedge forecasted non-functional currency cost of goods sold and forecasted non-functional currency selling, general and administrative expenses ("SG&A expenses") for our Australian subsidiaries. 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, costs of goods sold or SG&A expenses 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 December 31, 2025, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales and SG&A expenses to fluctuations in currency rates and no outstanding amounts to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. At December 31, 2025, there was a net realized gain of $1 million

TABLE OF CONTENTS
recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet, which is expected to be fully recognized in earnings during the year ended December 31, 2026.
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 Consolidated Statements 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 December 31, 2025, there was (i) 572 million South African Rand (or approximately $35 million at the December 31, 2025 exchange rate), (ii) 161 million Australian dollars (or approximately $108 million at the December 31, 2025 exchange rate), (iii) 213 million Pound Sterling (or approximately $286 million at the December 31, 2025 exchange rate, (iv) 50 million Euro (or approximately $59 million at the December 31, 2025 exchange rate) and (v) 83 million Saudi Riyal (or approximately $22 million at the December 31, 2025 exchange rate) of notional amount of outstanding foreign currency contracts.
17. Fair Value Measurement
For financial instruments that are subsequently measured at fair value, the fair value measurement is grouped into levels. See Note 2.
Our debt is recorded at historical amounts. The following table presents the fair value of our debt and derivative contracts at both December 31, 2025 and December 31, 2024:

| December 31, 2025 |  | December 31, 2024
| Asset | Liability |  | Asset | Liability
2024 Term Loan Facility | — |  | 605 |  |  | — |  | 744 |
2024-B Term Loan Facility | — |  | 684 |  |  | — |  | 904 |
RMB Term Loan Facility | — |  | 57 |  |  | — |  | 58 |
Senior Notes due 2029 | — |  | 754 |  |  | — |  | 966 |
Senior Secured Notes due 2030 | — |  | 399 |  |  | — |  | — |
Australian Government Loan | — |  | 2 |  |  | — |  | 1 |
MGT Loan | — |  | 13 |  |  | — |  | 19 |
Interest rate swaps | 7 |  | 1 |  |  | 33 |  | — |
Foreign currency contracts | 5 |  | — |  |  | 1 |  | 18 |

We determined the fair value of the 2024 Term Loan Facility, the 2024-B Term Loan Facility, the Senior Notes due 2029 and the Senior Secured Notes due 2030 using quoted market prices, which under the fair value hierarchy is a Level 1 input. We determined the fair value of the RMB Term Loan Facility utilizing transactions in the listed markets for 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 and accounts payable approximate fair value due to the short-term nature of these items.

TABLE OF CONTENTS
1 - Changes in estimates, including cost and timing of cash flows includes a charge of $11 million related to the Botlek plant closure and $1 million related to the Fuzhou plant closure, both recorded in "Restructuring and other charges" on the Consolidated Statements of Operations for the year ended December 31, 2025. Refer to note 3 for further details.

| December 31,
| 2025 |  | 2024
Asset retirement obligations were classified as follows: |  |  |
Current portion included in “Accrued liabilities” | $ | 17 |  |  | $ | 14 |
Noncurrent portion included in “Asset retirement obligations” | 198 |  |  | 172 |
Asset retirement obligations | $ | 215 |  |  | $ | 186 |

We used the following assumptions in determining asset retirement obligations at December 31, 2025: inflation rates between 1.6% - 5.5% per year; credit adjusted risk-free interest rates between 5.0% -20.1%; the life of mines from less than 1 to 45 years and the useful life of assets between 3-42 years.
Environmental Rehabilitation Scheme
In accordance with applicable regulations, we established an environmental rehabilitation scheme for the prospecting and mining operations in South Africa, which receives, holds, and invests funds for the rehabilitation or management of asset retirement obligations. At December 31, 2025 and 2024, the total value of the assets held in the environmental rehabilitation scheme were $19 million and $16 million, respectively, which were recorded in “Other long-term assets” in the Consolidated Balance Sheets.
20. Commitments and Contingencies
Purchase and Capital Commitments—At December 31, 2025, purchase commitments were $349 million for 2026, $313 million for 2027, $179 million for 2028, $145 million for 2029, $197 million for 2030, and $2,278 million thereafter.
Letters of Credit—At December 31, 2025, we had outstanding letters of credit and bank guarantees of $155 million, of which $65 million were letters of credit (inclusive of $47 million related to the sale of Hawkins Point as discussed below) and $90 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 are 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 TiO 2 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 ("MPE"). 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 Statements of Operations. As of December 31, 2025, we have a provision of $41 million, of which $26 million and $15 million is included in "Environmental liabilities" and "Accrued Liabilities", respectively, in our Consolidated Balance Sheet for the Hawkins Point Plant consistent with the accounting policy described above.

TABLE OF CONTENTS
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. The 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 February 12, 2025 and July 30, 2025 with respect to the Company's financial outlook and demand for its pigment and zircon products. The case is in its very early stages. No specific amount of damages has been alleged. The Company and the individual defendants intend to defend themselves vigorously against this lawsuit.

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 year ended December 31, 2025, we made no repurchases of the Company's stock.
22. Share-based Compensation
Share-based compensation expense consisted of the following:

| Year Ended December 31,

Total share-based compensation expense from restricted share units | $ | 20 |  |  | $ | 21 |  |  | $ | 21 |

Tronox Holdings plc Amended and Restated Management Equity Incentive Plan
On March 27, 2019, Tronox Holdings plc assumed the management equity incentive plan previously adopted by Tronox Limited, which plan was renamed the Tronox Holdings plc Amended and Restated Management Equity Incentive Plan. The MEIP permits the grant of awards that are comprised of incentive options, nonqualified options, share appreciation rights, restricted shares, restricted share units, performance awards, and other share-based awards, cash payments, and other forms as the compensation committee of the Board of Directors (the “Board”) in its discretion deems appropriate, including any combination of the above. The maximum number of shares which were initially subjected to awards (inclusive of incentive options) was 20,781,225 ordinary shares and was increased by 8,000,000 on the affirmative vote of our shareholders on June 24, 2020, and further increased by 3,200,000 on the affirmative vote of our shareholders on May 8, 2024.
108

TABLE OF CONTENTS
Restricted Share Units (“RSUs”)
On an annual basis, the Company grants RSUs which have time and/or performance conditions. Both the time-based awards and the performance-based awards are classified as equity awards.
2025 Grants- The Company granted both time-based and performance-based awards to certain members of management. A total of 1,896,879 of time-based awards were granted to management which will primarily vest ratably over a three-year period ending March 5, 2028. A total of 250,724 of time-based awards were granted to non-employee members of the Board which will vest in May 2026. A total of 1,497,218 of performance-based awards were granted, of which 748,609 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 748,609 of the awards vest based on certain performance metrics of the Company. The non-TSR performance-based awards vest on March 5, 2028 based on the actual 2027 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 $8.94.
Similar TSR awards were granted during 2024 and 2023 with a grant date fair values of $21.70 and $22.42 which was calculated utilizing a Monte Carlo simulation. The following weighted-average assumptions were utilized to value the grants in 2025, 2024 and 2023:

| 2025 |  | 2024 |  | 2023
Dividend yield | — | % |  | — | % |  | N/A
Expected historical volatility | 48.8 | % |  | 47.9 | % |  | 67.1 | %
Risk free interest rate | 4.30 | % |  | 4.46 | % |  | 4.47 | %
Expected life (in years) | 3 |  | 3 |  | 3

The following table presents a summary of activity for RSUs for 2025:

| Number of Shares |  | Weighted Average Grant Date Fair Value
Outstanding, January 1, 2025 | 3,468,774 |  |  | $ | 18.70 |
Granted | 3,644,821 |  |  | 7.56 |
Vested | (762,554) |  |  | 16.76 |
Forfeited | (659,750) |  |  | 22.90 |
Outstanding, December 31, 2025 | 5,691,291 |  |  | $ | 11.34 |
Expected to vest, December 31, 2025 | 2,678,341 |  |  | $ | 9.05 |

At December 31, 2025, there was $26 million of unrecognized compensation expense related to nonvested RSUs, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of 1.9 years. The weighted-average grant-date fair value of RSUs granted during 2025, 2024 and 2023 was $7.56 per unit, $16.69 per unit, and $16.33 per unit, respectively. The total fair value of RSUs that vested during 2025, 2024 and 2023 was $13 million, $23 million and $27 million, respectively.
23. Pension and Other Postretirement Healthcare Benefits
The following provides information regarding our U.S. and foreign plans:
U.S. Plans
Pension and Postretirement Healthcare Plans— Tronox has one main U.S. defined benefit plan: the U.S. Qualified Plan. The U.S. Qualified Plan is a funded noncontributory qualified benefit plan which is in accordance with the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Internal Revenue Code. We made contributions into funds managed by a third party, and those funds are held exclusively for the benefit of the plan participants. Benefits under the U.S. Qualified Plan were generally calculated based on years of service and final average pay. The U.S. Qualified Plan was frozen and closed to new participants on June 1, 2009. We also maintain one postretirement healthcare plan - the U.S. retiree welfare plan.
International Plans
109

TABLE OF CONTENTS
Pension Plans — Tronox has international defined benefit commitments primarily in the United Kingdom ("U.K. DB Scheme") and Saudi Arabia. The U.K. DB Scheme is a funded qualified defined benefit plan in the United Kingdom, which is frozen with no additional benefits accruing to the participants. Benefits under the U.K. DB Scheme are generally calculated based on years of credit service and final compensation when benefits ceased to accrue as defined under the plan provisions. During the year ended December 31, 2025, the trustees of the U.K. DB Scheme executed a bulk annuity buy-in for the plan with a third-party insurer for approximately GBP 30 million (approximately $40 million at the December 31, 2025 rate). As a result of this transaction, the U.K. DB Scheme obligations are now fully insured. We also maintain a Saudi Arabia Cristal End of Service Benefit plan which provides end of service benefits to qualifying participants. End of service benefits are based on years of service and the reasons for which a participant's services to the Company are terminated.
Multiemployer Pension Plan - In prior periods, we maintained a defined benefit plan in the Netherlands (the “Netherlands Plan”) to provide defined pension benefits to qualifying employees of Tronox Pigments (Holland) B.V. and its related companies. During 2014, the Netherlands Plan was replaced with a multiemployer plan, the Netherlands Contribution Plan (the "CDC Plan") effective January 1, 2015. Under the CDC Plan, employees earn benefits based on their pensionable salaries each year determined using a career average benefit formula. The collective bargaining agreement between us and the participants require us to contribute 19.8% of the participants’ pensionable salaries into a pooled fund administered by the industry-wide PGB. The pensionable salary is the annual income of employees subject to a cap, which is adjusted each year to reflect the current requirements of the Netherlands’ Wages and Salaries Tax Act of 1964. Our obligation under this plan is limited to the fixed percentage contribution we make each year. The employees are entitled to any returns generated from the investment activities of the fund.
The following table outlines the details of our participation in the CDC Plan for the year ended December 31, 2025. The CDC disclosures provided herein are based on the fund’s 2024 annual report, which is the most recently available public information. Based on the total plan assets and accumulated benefit obligation information in the plan’s annual report, the zone status was green as of December 31, 2024. A green zone status indicates that the plan was at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates whether a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. As of December 31, 2025, we are not aware of any financial improvement or rehabilitation plan being implemented or pending. The last column lists the expiration date of the collective-bargaining agreement to which the plan is subject.

|  |  |  | Pension Protection Act Zone Status |  |  |  | Tronox Contributions |  |  |  |
Pension Fund |  | EIN/Pension Plan Number |  | 2025 |  | 2024 |  | FIP/RP Pending/ Implemented |  | 2025 |  | 2024 |  | Surcharge Imposed |  | Expiration date of Collective- Bargaining Agreement
PGB |  | NA |  | N/A |  | Green |  | No |  | $ | 4 |  |  | $ | 5 |  |  | No |  | 12/31/2027*

*-A new collective bargaining agreement has been preliminarily negotiated with the new term expected to be for another five years.
On the basis of the information available in the CDC Plan 2024 annual report, our contribution does not constitute more than 5 percent of the total contribution to the plan by all participants. During 2025, the fund did not impose any surcharge on us.
Postretirement Healthcare Plans — We also maintain postretirement healthcare plans in South Africa (the "South African Plan") and Brazil (the "Brazil Medical Plan"). The South African Plan provides medical and dental benefits to certain South African employees, retired employees and their registered dependents. The South African Plan provides benefits as follows: (i) members employed before March 1, 1994 receive 100% post-retirement and death-in-service benefits; (ii) members employed on or after March 1, 1994 but before January 1, 2002 receive 2% per year of completed service subject to a maximum of 50% post-retirement and death-in-service benefits; and, (iii) members employed on or after January 1, 2002 receive no post-retirement and death-in-service benefits. The Brazil Medical Plan provides post-employment medical benefits to employees who contributed to the medical plan while employed. Retirees receiving a benefit under the plan are required to pay a contribution that varies based on the coverage level elected.
Pension and Postretirement Benefit Costs / Obligations
Benefit Obligations and Funded Status — The following provides a reconciliation of beginning and ending benefit obligations, beginning and ending plan assets, funded status, and balance sheet classification of our U.S. and international pension plans and other post-retirement benefit plans ("OPEB") as of and for the years ended December 31, 2025 and 2024. The benefit obligations and plan assets associated with our principal benefit plans are measured on December 31.

Contributions
At a minimum, Tronox contributes to its pension plans to comply with local regulatory requirements (e.g., ERISA in the United States). Discretionary contributions in excess of the local minimum requirements are made based on many factors, including long-term projections of the plans' funded status, the economic environment, potential risk of overfunding, pension insurance costs and alternative uses of the cash. Changes to these factors can impact the timing of discretionary contributions from year to year. Pension contributions for its US and international plans were approximately $4 million in 2025 and are currently expected to be approximately $10 million in 2026.
The following table provides information for pension plans where the accumulated benefit obligation exceeds the fair value of the plan assets:

For the U.S. Qualified Plan, at both December 31, 2025 and December 31, 2024, the mortality assumption was determined using the Society of Actuaries' the generational projection scale (i.e. MP-2021) and base table (i.e. Pri-2012).
Expected Return on Plan Assets — In forming the assumption of the U.S. and international long-term rate of return on plan assets, we considered the expected earnings on funds already invested, earnings on contributions expected to be received in the current year, and earnings on reinvested returns. The long-term rate of return estimation methodology for the Company's pension plans is based on a capital asset pricing model using historical data and a forecasted earnings model. An expected return on plan assets analysis is performed which incorporates the current portfolio allocation, historical asset-class returns, and an assessment of expected future performance using asset-class risk factors.
Discount Rate — The 2025 and 2024 rates were selected based on the results of a cash flow matching analysis, which projected the expected cash flows of the plans using a yield curves model developed from a universe of Aa-graded U.S. currency corporate bonds (obtained from Bloomberg) with BVAL scores of 6 or greater.
Plan Assets — The investments of the U.S. and International pension plans are managed to meet the future expected benefit liabilities of the plan over the long term by investing in diversified portfolios consistent with prudent diversification and historical and expected capital market returns. Tronox's U.S. and international pension plans’ weighted-average asset allocations at December 31, 2025 and 2024, and the target asset allocation ranges, by major asset category, are as follows:

TABLE OF CONTENTS
Defined Contribution Plans
U.S. Savings Investment Plan
In 2006, we established the U.S. Savings Investment Plan (the “SIP”), a qualified defined contribution plan under Section 401(k) of the Internal Revenue Code. Under the SIP, our regular full-time and part-time employees contribute a portion of their earnings, and we match these contributions up to a predefined threshold. Our matching contribution is 100% of the first 6% of employee contributions. Effective January 1, 2013, we established a profit sharing contribution at 6% of employees’ pay (“discretionary contribution”). A discretionary contribution of 6% was made for 2025, 2024 and 2023. Our matching contribution to the SIP vests immediately; however, our discretionary contribution is subject to vesting conditions that must be satisfied over a three-year vesting period. Contributions under the SIP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expenses associated with our matching contribution to the SIP was $5 million, $5 million and $4 million during 2025, 2024 and 2023, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations. Compensation expense associated with our discretionary contribution was $5 million in 2025, $4 million in 2024 and $5 million in 2023, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations.
U.S. Benefit Restoration Plan
In 2006, we established the U.S. Benefit Restoration Plan (the “BRP”), a nonqualified defined contribution plan, for employees whose eligible compensation is expected to exceed the IRS compensation limits for qualified plans. Under the BRP, participants can contribute up to 20% of their annual compensation and incentive. Our matching contribution under the BRP is the same as the SIP. Our matching contribution under this plan vests immediately to plan participants. Contributions under the BRP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expense associated with our matching contribution to the BRP was $1 million, $1 million and $1 million during 2025, 2024 and 2023, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations.
South Africa Defined Contribution Plans
Tronox Mineral Sands Proprietary Limited, a wholly owned subsidiary of the Company, participates in several defined contribution plans which are registered in the Republic of South Africa and are governed by the South African Pension Funds Act of 1956. These plans provide retirement and other benefits to all permanent employees, and where applicable, retired employees and their dependents. The Company contributes a range of 10% to 15% (depending on the plan) of the employees' predefined pre-tax pensionable earnings. Compensation expense associated with these plans was $8 million, $8 million, and $8 million during 2025, 2024 and 2023, respectively, which was included in both "Costs of goods sold" and "Selling, general and administrative expenses" in the Consolidated Statements of Operations.
24. Related Party Transactions
Tasnee / Cristal
At December 31, 2025 Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a subsidiary of Tasnee, owned 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"). Furthermore, pursuant to the Option Agreement we lent AMIC $125 million for capital expenditures and operational expenses intended to facilitate the start-up of the Slagger (the “Tronox Loans”).
On May 13, 2020, May 23, 2023 and February 21, 2024, we amended the Option Agreement with AMIC (the "First Amendment", the "Second Amendment", and the "Third Amendment", respectively, and collectively, the "Amendments") to establish a definitive period during which Tronox and AMIC would discuss whether, and under what circumstances Tronox may acquire the Slagger (the "Renegotiation Period"). In the Third Amendment, we extended the Renegotiation Period until December 31, 2024. Until that date, 65% of all chloride slag produced by the Slagger was delivered to Tronox as repayment in-kind of the Tronox Loans. The chloride slag was valued based on a widely published index for feedstock less an nominal discount (the "Slag Price"). Tronox purchased the remaining 35% of chloride slag produced by the Slagger in cash at the Slag Price.

TABLE OF CONTENTS
The Renegotiation Period expired on December 31, 2024 without any agreement regarding whether and under what circumstances Tronox would acquire the Slagger. Then on February 11, 2025, we entered into an agreement with AMIC and its wholly owned subsidiary, Advanced Smelting Industries Co. Ltd. ("ASIC") pursuant to which all provisions of the Option Agreement and all the related letter agreements referenced above were extinguished. This included the parties' respective rights and obligations in and to the Option Agreement and related letter agreements and any claims arising thereunder, except for AMIC's obligation to repay the remaining AMIC Loan balance and all interest accrued. Such final cash repayment occurred in February 2025. In addition, the parties agreed that through December 31, 2026, Tronox would purchase certain quantities of Slag from ASIC based on the Slag Price.
The following table shows the outstanding balance of the Tronox Loans, which on the Consolidated Balance Sheet is recorded in "Prepaid and other assets:

Amount due to AMIC for slag purchases | 3 |  |  | 6 |

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 Consolidated Statement of Operations and shown in the table below, the management fees per the Original Technical Services Agreement were recorded within "Other income, net" and other technical support fees, including fees per the Restated Technical Services Agreement, are recorded within "Selling, general and administrative" costs. From and after October 1, 2023, we no longer receive a management fee.

TABLE OF CONTENTS
On December 29, 2019, we entered into an agreement (the "MGT Purchase Agreement") with Cristal to acquire certain assets co-located at our Yanbu facility which produce metal grade TiCl4 ("MGT"). Consideration for the acquisition was 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 TiCl 4, which we supply by pipeline, for the production of titanium sponge, a precursor material used in the production of titanium metal. The terms of our supply of TiCl 4 to ATTM are set forth in the Amended and Restated TiCL 4 Supply Agreement by and among ATTM, Cristal and ourselves dated December 17, 2020 (the "ARTSA").
On December 17, 2020 we completed the MGT transaction. Repayment of the $36 million note payable is based on a fixed U.S. dollar 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 set forth in the ARTSA, then at our election we may terminate the MGT supply agreement with ATTM and will no longer owe any amount under the loan agreement with Cristal. We currently estimate the ultimate maturity to be between approximately two and three years, subject to actual future MGT production levels. The interest rate on the note payable is based on the SAIBOR plus a premium. As shown in the table below, the note payable is recorded within "Long-term debt, net" and "Long-term debt due within one year" on the Consolidated Balance Sheet.

| December 31,
| 2025 |  | 2024
Note payable, due within 1 year | 8 |  | 7
Note payable, due longer than 1 year from now | 5 |  | 12
Total outstanding note payable | 13 |  | 19

Amounts regarding interest expense and loan repayments for the MGT loan, which are recorded on the Consolidated Statement of Operations within “Interest expense” and “Net sales,” respectively, are shown below:

| December 31,
| 2025 |  | 2024 |  | 2023
Interest expense | 1 |  | 1 |  | 2
Loan Repayment via MGT delivered to ATTM | 6 |  | 6 |  | 6

As a result of these transactions we have entered into related to the MGT assets, Tronox purchases chlorine gas from ATTM for use in the production of MGT and such transactions are reflected as follows:

| December 31,
| 2025 |  | 2024 |  | 2023
Purchases of chlorine gas | 7 |  | 5 |  | 5

These purchases are subsequently recorded within “Cost of goods sold” on the Consolidated Statement of Operations. Amounts due at period end, which are presented below, are recorded within “Accrued liabilities” on the Consolidated Balance Sheet.

| December 31,
| 2025 |  | 2024
Amount due related to purchases of chlorine gas | 1 |  | 6

Due from ATTM for MGT deliveries | 5 |  | 14

On February 11, 2025, we entered into a Settlement Deed with AMIC, Cristal and ATTM (collectively, the "AMIC Parties"), pursuant to which we resolved certain outstanding matters related to Tronox and the AMIC Parties' performance of their respective obligations under the MGT Purchase Agreement and the ARTSA. Specifically, Cristal agreed to pay us approximately $2 million in cash in exchange for a mutual release of all claims arising prior to December 31, 2024 under the MGT Purchase Agreement and the ARTSA relating to, among other things, certain amounts related to MGT deliveries that were outstanding as of December 31, 2024. As part of the settlement, we also agreed to increase the MGT loan amount by approximately $300,000 and issue a credit note for ATTM's benefit of approximately $500,000.
25. Segment Information
We operate our business under one operating segment, Tronox, which is also our reportable segment. The Tronox segment produces feedstock materials that can be processed into TiO 2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and ultrafine TiO 2 used in certain specialty applications. Tronox derives revenue across the world and it manages the business activities on a consolidated basis. We account for a contract with our customer when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable.
The accounting policies of Tronox are the same as those described in the significant accounting policies in Note 2.
The Company's chief operating decision maker (“CODM”), who is the CEO, reviews financial information presented at the consolidated level and decides how to allocate resources based on financial metrics, including net income. In addition to these financial metrics, the CODM also reviews monthly production figures along with future global sales demand forecasts to make decisions about ongoing production levels and how to allocate resources. The measure of segment assets is reported on the balance sheet as total consolidated assets. The CODM uses such financial metrics, including net income, to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into the segment or into other parts of the organization, such as working capital needs, mandatory and discretionary capital expenditures, servicing our interest and debt repayment obligations, cash taxes, and making pension contributions.
Net income, other financial metrics, production costs and sales forecasts are used to monitor budget versus actual results. The CODM also uses these financial metrics as a percentage of sales in competitive analysis by benchmarking to Tronox’s competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment and in establishing management’s compensation. The reported segment revenue, segment profit or loss and significant segment expenses are the same as the consolidated results disclosed on the consolidated statement of operations, except as noted below. As noted above, the CODM also determines how to allocate resources through his review of monthly production / manufacturing costs. Significant segment expenses, other than those disclosed on the Consolidated Statements of Operations, are as follows:

|  | Year Ended December 31,
|  | 2025 |  | 2024 |  | 2023
Net Sales |  | $ | 2,898 |  |  | $ | 3,074 |  |  | $ | 2,850 |
Idle facility and lower of cost or net realizable value charges (a) |  | 139 |  |  | 117 |  |  | 159 |
Other cost of goods (b) |  | 2,490 |  |  | 2,442 |  |  | 2,229 |
Gross Profit |  | $ | 269 |  |  | $ | 515 |  |  | $ | 462 |
(a) Represents expenses during the period related to idle facility charges associated with production levels as well as charges related to reducing inventory to net realizable value when lower than production cost.
(b) Represents all other productions related costs associated with cost of goods sold during the respective periods including salaries, ore costs, electricity, process chemicals, maintenance and other.

We disaggregate revenue from contracts with customers by product type and geographic area as well as sales based on country of production. 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.

Item 9A. 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 December 31, 2025, the end of the period covered by this report. Based on that evaluation, our CEO and CFO have concluded that the Company's disclosure controls and procedures were effective as of that date. Tronox's disclosure controls and procedures are designed to ensure that information required to be disclosed by Tronox in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms, and that such information is accumulated and communicated to Tronox's management, including Tronox's CEO and CFO, or other person performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
Management’s Report on Internal Control Over Financial Reporting
Management of Tronox Holdings plc and its subsidiaries is responsible for establishing and maintaining adequate internal control over financial reporting. Internal controls over financial reporting is a process designed under the supervision of our interim principal co-executive officers and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with U.S. generally accepted accounting principles.
Our internal controls over financial reporting include those policies and procedures that:
•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;
•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of the Company’s management and directors; and
•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.
Management assessed the effectiveness of our internal controls over financial reporting as of December 31, 2025. In making this assessment, management used the criteria in Internal Control-Integrated Framework (2013) set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our assessment using those criteria, management concluded that our internal control over financial reporting as of December 31, 2025 was effective.
Because of its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which appears in Item 8 of this Form 10-K.
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 second and third quarters of 2025, 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, there have been no changes to our internal control over financial reporting during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
