#### NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
**March 31, 2026**

**(unaudited)**

#### Note 1 - Organization and basis of presentation:
*Organization* - At March 31, 2026 Valhi, Inc. (NYSE: VHI) held approximately 50% of our outstanding common stock and a wholly-owned subsidiary of NL Industries, Inc. (NYSE: NL) held approximately 31% of our common stock. Valhi owned approximately 83% of NL's outstanding common stock and a wholly-owned subsidiary of Contran Corporation held approximately 91% of Valhi's outstanding common stock. A majority of Contran's outstanding voting stock is held directly by Lisa K. Simmons and by family stockholders (Thomas C. Connelly (the husband of Ms. Simmons' late sister), a family-owned entity and various family trusts established for the benefit of Ms. Simmons, Mr. Connelly and their children) who are required to vote their shares of Contran voting stock in the same manner as Ms. Simmons. Such voting rights are personal to Ms. Simmons and last through April 22, 2030. The remainder of Contran's outstanding voting stock is held by another trust (the "Family Trust"), which was established for the benefit of Ms. Simmons and her late sister and their children and for which a third-party financial institution serves as trustee. Consequently, at March 31, 2026, Ms. Simmons and the Family Trust may be deemed to control Contran, and therefore may be deemed to indirectly control the wholly-owned subsidiary of Contran, Valhi, NL and us.

*Basis of presentation* - The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2025 that we filed with the Securities and Exchange Commission ("SEC") on March 9, 2026 ("2025 Annual Report"). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments), in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet at December 31, 2025 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2025) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Our results of operations for the interim period ended March 31, 2026 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2025 Consolidated Financial Statements contained in our 2025 Annual Report.

Unless otherwise indicated, references in this report to "we," "us" or "our" refer to Kronos Worldwide, Inc. and its subsidiaries (NYSE: KRO) taken as a whole.

#### Note 2 - TiO<sub>2</sub> segment information:
Our chief operating decision maker ("CODM") evaluates the TiO<sub>2</sub> segment's operating performance based on net income (loss) and segment profit (a non-GAAP measure), which we define as net income (loss) before income tax expense and certain general corporate items. These general corporate items include corporate expense and the components of other income (expense) except for trade interest income. Differences between segment profit and the amounts included in consolidated net income (loss) are shown in the table below. Trade interest income included in the calculation of segment profit is not significant for the three months ended March 31, 2025 or 2026. Substantially all depreciation expense is included in the calculation of segment profit for the three months ended March 31, 2026.

---

The amount shown in the preceding table of our income tax rate reconciliation for incremental tax benefit on losses of subsidiary represents current and deferred U.S. income tax benefits attributable to one of our non-U.S. subsidiaries which is treated as a dual resident for U.S. income tax purposes.

On July 4, 2025, the One Big Beautiful Bill Act was signed into law in the United States. It did not have a material impact on our consolidated financial statements.

Tax authorities are examining certain of our U.S. and non-U.S. tax returns and may propose tax deficiencies, including penalties and interest. In March 2026, we received notices of assessment from the German tax authorities for tax years 2019 through 2021. We disagree with the assessments and have filed notice of appeal. However, due to the uncertainty of the appeal and the complexity of the appeal process, during the first quarter of 2026 we recorded net income tax expense of $2.0 million to establish an uncertain tax position, net of amounts expected to be received from other taxing jurisdictions.

We believe we have adequate accruals for additional taxes and related interest expense which could ultimately result from tax examinations. We believe the ultimate disposition of tax examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

#### Note 13 - Commitments and contingencies:
We are involved in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business. At least quarterly our management discusses and evaluates the status of any pending litigation to which we are a party. The factors considered in such evaluation include, among other things, the nature of such pending cases, the status of such pending cases, the advice of legal counsel and our experience in similar cases (if any). Based on such evaluation, we make a determination as to whether we believe (i) it is probable a loss has been incurred, and if so if the amount of such loss (or a range of loss) is reasonably estimable, or (ii) it is reasonably possible but not probable a loss has been incurred, and if so if the amount of such loss (or a range of loss) is reasonably estimable, or (iii) the probability a loss has been incurred is remote. We have not accrued any amounts for litigation matters because it is not reasonably possible, we have incurred a loss that would be material to our consolidated financial statements, results of operations or liquidity.

#### Note 14 - Financial instruments:
See Note 5 for information on how we determine fair value of our marketable securities.

The following table presents the financial instruments that are not carried at fair value but which require fair value disclosure:

| &nbsp;&nbsp;&nbsp;&nbsp;Fixed rate 9.50% Senior Secured Notes due 2029 | 503.7 | 469.9 | **490.9** | **416.7** |
| &nbsp;&nbsp;&nbsp;&nbsp;Revolving credit facility | - | - | **58.1** | **58.1** |

---

At December 31, 2025 and March 31, 2026, the estimated market price of our 9.50% Senior Secured Notes due 2029 was €937 and €853 per €1,000 principal amount, respectively. The fair value of our Senior Secured Notes due 2029 was based on quoted market prices; however, these prices represented Level 2 inputs because the market in which the notes trade was not active. Due to the variable interest rate, the carrying amount of our revolving credit facility is deemed to approximate fair value. Due to their near-term maturities, the carrying amounts of accounts receivable and accounts payable are considered equivalent to fair value. See Notes 3 and 7.

**Note 15 – Restructuring costs:**

In the fourth quarter of 2025, we initiated a restructuring plan through workforce reductions which is supporting an improved current and longer-term cost structure. These workforce reductions impacted approximately 226 positions with a substantial portion of such reductions accomplished through involuntary programs. A portion of the reductions was also accomplished through voluntary programs, for which eligible workforce reduction costs were recognized at the time both the employee and employer were irrevocably committed to the terms of the separation. During the fourth quarter of 2025, we recognized an aggregate $10.3 million charge related to these workforce reductions. Accrued severance costs remaining at March 31, 2026 are expected to be substantially paid in 2026 and are included in accounts payable and accrued liabilities – other on our Condensed Consolidated Balance Sheet, see Note 7. We do not expect to accrue any further material amounts for the workforce reductions.

A summary of the activity in our accrued restructuring costs for the first three months of 2026 is shown in the table below:

---

| | |
|:---|:---|
|  | **Amount** |
|  | **(in millions)** |
| Accrued workforce reduction costs at December 31, 2025 | $**8.8** |
| Workforce reduction costs accrued | **-** |
| Workforce reduction costs paid | **(1.5)** |
| Currency translation adjustments, net | **(.2)** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Current liability at March 31, 2026 | $**7.1** |

**Note 16 - Recent accounting pronouncements:**

In November 2024, the FASB issued ASU No. 2024-03, *Reporting Comprehensive Income - Expense Disaggregation Disclosures*. The ASU requires additional information about specific expense categories in the notes to financial statements for both interim and annual reporting periods. The ASU is effective for us beginning with our 2027 Annual Report, and for interim reporting, in the first quarter of 2028, with early adoption permitted. We are in the process of evaluating the additional disclosure requirements.

#### ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

#### RESULTS OF OPERATIONS

#### Business overview
We are a leading global producer and marketer of value-added titanium dioxide pigments ("TiO<sub>2</sub>"). TiO<sub>2</sub> is used for a variety of manufacturing applications, including paints, plastics, paper and other industrial and specialty products. For the three months ended March 31, 2026, approximately 40% of our sales volumes were sold into European markets. Our production facilities are located in Europe and North America.

We consider TiO<sub>2</sub> to be a "quality of life" product, with demand affected by gross domestic product, or GDP, and overall economic conditions in our markets located in various regions of the world. Over the long-term, we expect demand for TiO<sub>2</sub> will grow by 2% to 3% per year, consistent with our expectations for the long-term growth in GDP. However, even if we and our competitors maintain consistent shares of the worldwide market, demand for TiO<sub>2</sub> in any interim or annual period may not change in the same proportion as the change in GDP, in part due to relative changes in the TiO<sub>2</sub> inventory levels of our customers. We believe our customers' inventory levels are influenced in part by their expectation for future changes in TiO<sub>2</sub><sub> </sub>selling prices as well as their expectation for future availability of product. Although certain of our TiO<sub>2</sub><sub> </sub>grades are considered specialty pigments, the majority of our grades and substantially all of our production are considered commodity pigment products with price and availability being the most significant competitive factors along with product quality and customer and technical support services.

The factors having the most impact on our reported operating results are:

● TiO <sub>2</sub> selling prices,

● TiO <sub>2</sub> sales and production volumes,

● Manufacturing costs, particularly raw materials such as third-party feedstock, maintenance and energy-related expenses, and

● Currency exchange rates (particularly the exchange rate for the U.S. dollar relative to the euro, the Norwegian krone and the Canadian dollar and the euro relative to the Norwegian krone).

Our key performance indicators are our TiO<sub>2</sub> average selling prices, our level of TiO<sub>2</sub> sales and production volumes and the cost of titanium-containing feedstock purchased from third parties. TiO<sub>2</sub><sub> </sub>selling prices generally follow industry trends, and selling prices will increase or decrease generally as a result of competitive market pressures.

#### Executive summary
We reported a net loss of $4.8 million, or $.04 per share, in the first quarter of 2026 compared to net income of $18.1 million, or $.16 per share, in the first quarter of 2025. Net income decreased in the first quarter of 2026 compared to the prior year period primarily due to lower income from operations as a result of lower average TiO<sub>2</sub> selling prices and lower production volumes, partially offset by higher sales volumes and lower production costs driven primarily by cost reduction initiatives implemented in the fourth quarter of 2025 to structurally realign our operations, as well as lower raw material and energy costs. Comparability of our results was also impacted by the effects of changes in currency exchange rates.

Our net loss for the three months ended March 31, 2026 includes an income tax expense of $2.0 million ($.02 per share) to recognize an uncertain tax position related to a German tax audit.

● Fluctuations in currency exchange rates (such as changes in the exchange rate between the U.S. dollar and each of the euro, the Norwegian krone and the Canadian dollar and between the euro and the Norwegian krone), or possible disruptions to our business resulting from uncertainties associated with the euro or other currencies;

● Our ability to renew or refinance credit facilities or other debt instruments in the future;

● Changes in interest rates;

● Our ability to comply with covenants contained in our revolving bank credit facility;

● Our ability to maintain sufficient liquidity;

● The ultimate outcome of income tax audits, tax settlement initiatives or other tax matters, including future tax reform;

● Environmental matters (such as those requiring compliance with emission and discharge standards for existing and new facilities);

● Government laws and regulations and possible changes therein including new environmental, sustainability, health and safety, or other regulations (such as those seeking to limit or classify TiO <sub>2</sub> or its use); and

● Pending or possible future litigation or other actions.

Should one or more of these risks materialize (or the consequences of such a development worsen), or should the underlying assumptions prove incorrect, actual results could differ materially from those forecasted or expected. We disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of changes in information, future events or otherwise.

#### Results of operations

#### Current industry conditions
We started 2026 with average TiO<sub>2</sub> selling prices lower than at the beginning of 2025; however, our average TiO<sub>2</sub> selling prices increased 2% during the first quarter of 2026. Our average TiO<sub>2</sub> selling prices in the first quarter of 2026 were 6% lower than average TiO<sub>2</sub> selling prices during the first quarter of 2025. Overall, our sales volumes increased in the first quarter of 2026 compared to the same period in 2025 due to higher overall sales volumes in the North American, Latin American and export markets partially offset by lower sales volumes in our European market.

During the fourth quarter of 2025, we implemented cost reduction initiatives, including workforce reductions and other measures, to permanently improve our cost structure and enable more efficient operation of our facilities at lower production rates for extended periods. As a result, beginning in the first quarter of 2026, our normal production capacity range has been adjusted to reflect our production capabilities under this new cost structure.

Excluding the effect of changes in currency exchange rates, our cost of sales per metric ton of TiO<sub>2</sub> sold in the first quarter of 2026 was lower as compared to the first quarter of 2025 due to decreases in per metric ton production costs driven primarily by the cost reduction initiatives discussed above, as well as lower raw material and energy costs.

\* Thousands of metric tons

(1) We use segment profit to assess the performance of our TiO<sub>2</sub> operations. Segment profit is defined as net income (loss) before income tax expense and certain general corporate items. The general corporate items include corporate expense and the components of other income (expense) except for trade interest income.

*Net sales* - Net sales in the first quarter of 2026 increased 4%, or $20.0 million, compared to the first quarter of 2025 primarily due to the effects of a 4% increase in sales volumes (which increased net sales by approximately $20 million) and the favorable impact of changes in currency exchange rates (primarily the euro) which we estimate increased our net sales by approximately $30 million. These increases were partially offset by a 6% decrease in average TiO<sub>2 </sub>selling prices (which decreased net sales by approximately $30 million). TiO<sub>2</sub> selling prices will increase or decrease generally as a result of competitive market pressures, changes in the relative level of supply and demand as well as changes in raw material and other manufacturing costs.

Our sales volumes increased 4% in the first quarter of 2026 as compared to the first quarter of 2025 primarily due to higher sales volumes in our North American, Latin American and export markets partially offset by lower sales volumes in our European market. The incremental market share gains we achieved in our European market during the second half of 2025, primarily as a result of competitor plant closures, continued into the first quarter of 2026. However, gains were not sufficient to offset the underlying decline in overall European demand.

*Cost of sales and gross margin* - Cost of sales increased by $43.5 million, or 11%, in the first quarter of 2026 compared to the first quarter of 2025 due to the effects of a 4% increase in sales volumes and the unfavorable impact from changes in currency exchange rates, partially offset by lower production costs driven primarily by the cost reduction initiatives as well as lower raw material and energy costs. In addition, unabsorbed fixed costs were not material in the first quarter of 2026 compared to $10 million of unabsorbed fixed costs in the first quarter of 2025.

Our cost of sales as a percentage of net sales increased to 84% in the first quarter of 2026 compared to 78% in the same period of 2025, as the unfavorable impact of lower average TiO<sub>2</sub> selling prices more than offset the favorable effects of lower production costs.

Gross margin as a percentage of net sales decreased to 16% in the first quarter of 2026 compared to 22% in the first quarter of 2025. As discussed and quantified above, our gross margin as a percentage of net sales decreased primarily due to the net effects of higher sales volumes, lower average TiO<sub>2</sub> selling prices, lower production costs and changes in currency exchange rates.

[**Table of Contents**](#TOC)

*Selling, general and administrative expense* - Selling, general and administrative expense increased $2.0 million, or 3%, in the first quarter of 2026 compared to the first quarter of 2025 as the negative impact of currency exchange rates exceeded the benefits of lower costs during the quarter. Excluding the effects of currency exchange rates, we realized lower selling, general and administrative expenses as a result of (i) realization of cost savings as a result of the fourth quarter of 2025 restructuring, (ii) lower warehousing costs due to lower average finished products inventory volumes and (iii) non-recurring distribution costs incurred in the first quarter of 2025 associated with tariff mitigation strategies. Selling, general and administrative expense as a percentage of net sales decreased to 12% in the first quarter of 2026 compared to 13% in the first quarter of 2025 due to the effects of higher sales.

*Segment profit* - Segment profit decreased by $26.5 million to $15.1 million in the first quarter of 2026 compared to $41.6 million in the first quarter of 2025, primarily as a result of the factors impacting gross margin discussed above. We estimate that changes in currency exchange rates decreased segment profit by approximately $6 million in the first quarter of 2026 compared to the same period in 2025, as discussed in the effects of currency exchange rates section below.

*Other non-operating income (expense)* - Interest expense in the first quarter of 2026 increased by $2.7 million compared to the first quarter of 2025 primarily due to higher average debt balances and higher interest rates. See Note 6 to our Condensed Consolidated Financial Statements. We recognized an unrealized gain of $.3 million in the first quarter of 2026 related to the change in marketable equity securities compared to an unrealized loss of $1.0 million in the same period of 2025.

*Income tax expense* - We recognized income tax expense of $2.8 million in the first quarter of 2026 compared to income tax expense of $7.6 million in the first quarter of 2025. The decrease is primarily due to lower earnings in the first quarter of 2026 and the jurisdictional mix of such earnings somewhat offset by a net uncertain tax position of $2.0 million recognized in the first quarter of 2026. Our earnings and losses are subject to income tax in various U.S. and non-U.S. jurisdictions, and the income tax rates applicable to the pre-tax earnings (losses) of our non-U.S. operations are generally higher than the income tax rates applicable to our U.S. operations. We would generally expect our overall effective tax rate, excluding the effect of any increase or decrease in our deferred income tax asset valuation allowance, changes in our reserve for uncertain tax positions, or tax rate changes to be higher than the U.S. federal statutory tax rate of 21% primarily because of our sizeable non-U.S. operations. See Note 11 to our Condensed Consolidated Financial Statements.

**Effects of currency exchange rates**

We have substantial operations and assets located outside the United States (primarily in Germany, Belgium, Norway and Canada). The majority of our sales from non-U.S. operations are denominated in currencies other than the U.S. dollar, principally the euro, other major European currencies and the Canadian dollar. A portion of our sales generated from our non-U.S. operations is denominated in the U.S. dollar (and consequently our non-U.S. operations will generally hold U.S. dollars from time to time). Certain raw materials used in all our production facilities, primarily titanium-containing feedstocks, are purchased primarily in U.S. dollars, while labor and other production and administrative costs are incurred primarily in local currencies. Consequently, the translated U.S. dollar value of our non-U.S. sales and operating results are subject to currency exchange rate fluctuations which may favorably or unfavorably impact reported earnings and may affect the comparability of period-to-period operating results. In addition to the impact of the translation of sales and expenses over time, our non-U.S. operations also generate currency transaction gains and losses which primarily relate to (i) the difference between the currency exchange rates in effect when non-local currency sales or operating costs (primarily U.S. dollar denominated) are initially accrued and when such amounts are settled with the non-local currency, (ii) changes in currency exchange rates during time periods when our non-U.S. operations are holding non-local currency (primarily U.S. dollars), and (iii) relative changes in the aggregate fair value of currency forward contracts held from time to time. We periodically use currency forward contracts to manage a portion of our currency exchange risk, and relative changes in the aggregate fair value of any currency forward contracts we hold from time to time serves in part to mitigate the currency transaction gains or losses we would recognize from the first two items described above.

Fluctuations in currency exchange rates had the following effects on our sales and income from operations for the periods indicated.

---

The $30 million increase in net sales (translation gains) was caused primarily by a weakening of the U.S. dollar relative to the euro, as our euro-denominated sales were translated into more U.S. dollars in 2026 as compared to 2025. The weakening of the U.S. dollar relative to the Canadian dollar and the Norwegian krone in 2026 did not have a significant effect on our net sales, as a substantial portion of the sales generated by our Canadian and Norwegian operations is denominated in the U.S. dollar.

The $6 million decrease in income from operations was comprised of the following:

● Higher net currency transaction losses of approximately $1 million primarily caused by relative changes in currency exchange rates at each applicable balance sheet date between the U.S. dollar and the euro, Canadian dollar and the Norwegian krone, and between the euro and the Norwegian krone, which causes increases or decreases, as applicable, in U.S. dollar-denominated receivables and payables and U.S. dollar currency held by our non-U.S. operations, and in Norwegian krone denominated receivables and payables held by our non-U.S. operations. In the first quarter of 2025, we entered into a currency forward contract to purchase €25 million at an exchange rate of €1.05 per U.S. dollar. We recognized a $.9 million currency transaction gain which was included in our Condensed Consolidated Statement of Operations for the three months ended March 31, 2025, and

● Approximately $5 million from net currency translation losses primarily caused by a weakening of the U.S. dollar relative to the Canadian dollar, Norwegian krone and euro, as local currency-denominated operating costs were translated into more U.S dollars in 2026 as compared to 2025. The net translation gains from the favorable effects of the weaker U.S dollar on euro-denominated sales more than offset the negative effects on euro-denominated operating costs being translated into more U.S. dollars in 2026 as compared to 2025.

#### Outlook
During the first quarter of 2026, sales volumes improved compared to the same period in 2025, primarily driven by higher sales volumes in our North American, Latin American, and export markets. While we gained market share in Europe as a result of competitor capacity reductions in 2025, these gains were not sufficient to offset further weakening end-market demand in the region. Although customers remain reluctant to build inventory, order lead times have increased, which provides us with greater flexibility in near- and intermediate-term production planning. Our order backlog at the beginning of 2026 was generally higher than the comparable prior-year period and has continued to show positive trends entering the second quarter. However, overall demand remains below historical levels, and the timing and sustainability of a broader market recovery remain uncertain. We implemented price increases during the first quarter of 2026; however, selling prices remain below 2025 levels, and additional price increases will be required to improve our operating margins.

During the fourth quarter of 2025, we implemented cost reduction initiatives, including workforce reductions and other measures, to permanently improve our cost structure and enable more efficient operation of our facilities at lower production rates for extended periods. We operated our facilities slightly below normal capacity during the first quarter of 2026. Our operating model balances improved cost efficiency with flexibility to respond to changes in demand. During the first quarter of 2026, we sold through higher cost inventory produced in the fourth quarter of 2025 and expect gross margin to improve as we realize the benefit of lower cost inventory produced during 2026.

Industry supply conditions tightened during the first quarter of 2026 due to the recent geopolitical conflict in the Middle East and related supply chain disruptions, including sulfuric acid pricing pressures, and higher energy costs, particularly in Europe. As a result, we are beginning to experience higher shipping and production costs driven primarily by increased energy, utility and raw material costs, especially in Europe. These cost pressures are expected to persist as long as uncertainty related to the conflict in the Middle East and broader global conditions continue. In response to rising costs, we implemented surcharges in most major markets and announced

[**Table of Contents**](#TOC)

price increases effective in the second quarter of 2026. We expect TiO₂ selling prices to continue to rise during 2026, which would help mitigate increases in distribution, raw material, energy, and other production costs, although margins will remain below historical levels.

We are focused on improving operating margins through pricing actions, disciplined cost management, and continued execution of our operating cost structural realignment initiatives. We are also continuing to pursue targeted market share opportunities in regions and markets impacted by competitor curtailments, closures, logistical disruptions, or trade measures such as tariffs or duties that have reduced the competitiveness of low-cost imports. These actions are intended to support improved operating performance while maintaining flexibility in the event of continued demand volatility.

Liquidity and capital resources remain sufficient to support our operations and planned capital investments. While we typically experience significant seasonal cash usage in the first quarter, we expect cash on hand to improve over the remainder of the year. We will continue to actively manage working capital, including inventories and receivables, to bolster operating cash flows and maintain financial flexibility. We believe our revolver availability, combined with the absence of near-term debt maturities and improved operating cash flows, will provide adequate liquidity for expected working capital needs and capital allocation requirements.

Our expectations for the TiO<sub>2</sub> industry and our operations are based on a number of factors outside our control. Our operations are affected by global and regional economic, political and regulatory factors, and we have experienced global market disruptions. Future impacts on our operations will depend on, among other things, future energy costs, the effect of newly enacted tariffs in jurisdictions where we or our customers and suppliers operate, our success in implementing mitigation strategies, and the impact of economic conditions, consumer confidence, and geopolitical events on our operations or our customers' and suppliers' operations, all of which remain uncertain and cannot be predicted.

#### LIQUIDITY AND CAPITAL RESOURCES

#### Consolidated cash flows

#### Operating activities
Trends in cash flows as a result of our operating activities (excluding the impact of significant asset dispositions and relative changes in assets and liabilities) are generally similar to trends in our earnings. In addition to the impact of the operating, investing and financing cash flows discussed below, changes in the amount of cash, cash equivalents and restricted cash we report from period to period can be impacted by changes in currency exchange rates, since a portion of our cash, cash equivalents and restricted cash is held by our non-U.S. subsidiaries.

Cash used in operating activities was $51.3 million in the first three months of 2026 compared to cash used of $102.4 million in the first three months of 2025. This $51.1 million decrease in the amount of cash used in operating activities was primarily due to the net effect of the following:

● lower amount of net cash used associated with relative changes in our inventories, receivables, payables and accruals in 2026 of $70.6 million,

● lower income from operations in 2026 of $25.8 million, and

● higher cash paid for interest in 2026 of $6.5 million primarily due to increased debt levels and higher average interest rates relative to the comparable period in 2025 and the timing of interest payments.

Changes in working capital were affected by accounts receivable and inventory changes. As shown below:

● Our average days sales outstanding, or DSO, increased from December 31, 2025 to March 31, 2026 primarily due to the relative changes in the timing of sales and collections, and

● Our average days sales in inventory, or DSI, decreased from December 31, 2025 to March 31, 2026 primarily due to lower inventory volumes as sales volumes exceeded production volumes during the first quarter of 2026.

#### Investing activities
Our capital expenditures of $10.2 million and $12.0 million in the first three months of 2026 and 2025, respectively, were primarily to maintain and improve the cost effectiveness of our manufacturing facilities.

#### Financing activities
During the first three months of 2026 and 2025, we paid dividends of $.05 per share to stockholders aggregating $5.8 million each period.

During the first three months of 2026 and 2025, we had net borrowings of $58.9 million and $32.9 million, respectively, on our revolving credit facility.

#### Outstanding debt obligations
At March 31, 2026, our consolidated debt comprised:

● €426.174 million aggregate outstanding on our 9.50% Senior Secured Notes due March 2029 ($490.9 million carrying amount, net of unamortized premium and unamortized debt issuance costs),

● $53.7 million outstanding on our subordinated, unsecured term loan from Contran, with an interest rate of 9.54%, due September 2029 (the "Contran Term Loan"), and

● $58.1 million outstanding on our revolving credit facility (the "Global Revolver").

Availability under the Global Revolver is subject to a borrowing base calculation, as defined in the agreement. The borrowing base calculated for the period ended March 31, 2026 was approximately $287 million.

Our Senior Secured Notes, the Contran Term Loan and our Global Revolver contain a number of covenants and restrictions which, among other things, restrict our ability to incur or guarantee additional debt, incur liens, pay dividends or make other restricted payments, or merge or consolidate with, or sell or transfer substantially all of our assets to, another entity, and contain other provisions and restrictive covenants customary in lending transactions of these types. Our credit agreements contain provisions which could result in the acceleration of indebtedness prior to their stated maturity for reasons other than defaults for failure to comply with typical financial or payment covenants. For example, the credit agreements allow the lender to accelerate the maturity of the indebtedness upon a change of control (as defined in the agreement) of the borrower. In addition, the credit agreements could result in the acceleration of all or a portion of the indebtedness following a sale of assets outside the ordinary course of business. The terms of all of our debt instruments are discussed in Note 8 to our Consolidated Financial Statements included in our 2025 Annual Report. We are in compliance with all of our debt covenants at March 31, 2026. We believe we will be able to continue to comply with the financial covenants contained in our credit facility through its maturity; however, if future operating results differ materially from our expectations we may be unable to maintain compliance.

Our assets consist primarily of investments in operating subsidiaries, and our ability to service our obligations, including the Senior Secured Notes and the Contran Term Loan, depends in part upon the distribution of earnings of our subsidiaries, whether in the form of dividends, advances or payments on account of intercompany obligations or otherwise. Our Senior Secured Notes are collateralized by, among other things, a first priority lien on (i) 100% of the common stock or other ownership interests of each existing and future direct domestic subsidiary of KII and the guarantors, and (ii) 65% of the voting common stock or other ownership interests and 100% of the non-voting common stock or other ownership interests of each non-U.S. subsidiary that is directly owned by KII or any guarantor. Our Global Revolver is collateralized by, among other things, a first priority lien on the borrower's trade receivables and inventories. See Note 6 to our Condensed Consolidated Financial Statements.

#### Future cash requirements

#### Liquidity
Our primary source of liquidity on an ongoing basis is cash flows from operating activities which is generally used to (i) fund capital expenditures, (ii) repay any short-term indebtedness incurred for working capital purposes, (iii) provide for the payment of dividends and (iv) fund purchases of shares of our common stock under our stock repurchase program. From time-to-time we will incur indebtedness, generally to (i) fund short-term working capital needs, (ii) refinance existing indebtedness or (iii) fund major capital expenditures or the acquisition of other assets outside the ordinary course of business. We will also from time-to-time sell assets outside the ordinary course of business and use the proceeds to (i) repay existing indebtedness, (ii) make investments in marketable and other

[**Table of Contents**](#TOC)

securities, (iii) fund major capital expenditures or the acquisition of other assets outside the ordinary course of business or (iv) pay dividends.

The TiO<sub>2</sub> industry is cyclical, and changes in industry economic conditions significantly impact earnings and operating cash flows. Changes in TiO<sub>2</sub> pricing, production volumes and customer demand, among other things, could significantly affect our liquidity.

We routinely evaluate our liquidity requirements, alternative uses of capital, capital needs and availability of resources in view of, among other things, our dividend policy, our debt service, our capital expenditure requirements and estimated future operating cash flows. As a result of this process, we have in the past and may in the future seek to reduce, refinance, repurchase or restructure indebtedness, raise additional capital, repurchase shares of our common stock, modify our dividend policy, restructure ownership interests, sell interests in our subsidiaries or other assets, or take a combination of these steps or other steps to manage our liquidity and capital resources. Such activities have in the past and may in the future involve related companies. We may also from time to time engage in preliminary discussions with existing or potential investors regarding the timing or terms of any such refinancing or other potential transaction. In the normal course of our business, we may investigate, evaluate, discuss and engage in acquisition, joint venture, strategic relationship and other business combination opportunities in the TiO<sub>2</sub><sub> </sub>industry. In the event of any future acquisition or joint venture opportunity, we may consider using then-available liquidity, issuing our equity securities or incurring additional indebtedness.

At March 31, 2026, we had aggregate cash, cash equivalents and restricted cash on hand of $33.6 million, of which $23.7 million was held by non-U.S. subsidiaries. Following implementation of a territorial tax system under the 2017 Tax Act, repatriation of any cash and cash equivalents held by our non-U.S. subsidiaries would not be expected to result in any material income tax liability as a result of such repatriation. Based upon our expectations of our operating performance and the anticipated demands on our cash resources, we expect to have sufficient liquidity to meet our short-term obligations (defined as the twelve-month period ending March 31, 2027) and our long-term obligations (defined as the five-year period ending March 31, 2031, our time period for long-term budgeting). Our Global Revolver matures in July 2029, and at March 31, 2026, we had total availability for borrowing of approximately $287 million less any amounts outstanding under this facility. The borrowing base is calculated at least quarterly, and the amount available for borrowing may change based on applicable period end balances. See Note 6 to our Condensed Consolidated Financial Statements.

#### Capital expenditures
We intend to invest approximately $60 million in capital expenditures primarily to maintain and improve our existing facilities during 2026, including $10.2 million in expenditures through March 31, 2026. It is possible we will delay planned capital projects based on market conditions including but not limited to expected demand and the general availability of materials, equipment and supplies necessary to complete such projects.

#### Stock repurchase program
At March 31, 2026, we have 1,017,518 shares available for repurchase under a stock repurchase program authorized by our board of directors.

#### Commitments and contingencies
See Notes 11 and 13 to our Condensed Consolidated Financial Statements for a description of certain income tax contingencies and certain legal proceedings.

#### Recent accounting pronouncements
See Note 16 to our Condensed Consolidated Financial Statements.

#### Critical accounting policies
For a discussion of our critical accounting policies, refer to Part I, Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2025 Annual Report. There have been no changes in our critical accounting policies during the first three months of 2026.

#### ITEM 3.&nbsp;&nbsp;&nbsp;&nbsp;QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

#### General
We are exposed to market risk, including currency exchange rates, interest rates, equity security and raw material prices. There have been no material changes in these market risks since we filed our 2025 Annual Report. See also Part I, Item 7A. - "Quantitative and Qualitative Disclosure About Market Risk" in our 2025 Annual Report and Note 14 to our Condensed Consolidated Financial Statements.

#### ITEM 4.&nbsp;&nbsp;&nbsp;&nbsp;CONTROLS AND PROCEDURES

#### Evaluation of disclosure controls and procedures
We maintain disclosure controls and procedures which, as defined in Exchange Act Rule 13a-15(e), means controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit to the SEC under the Securities Exchange Act of 1934, as amended (the "Act"), is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information we are required to disclose in the reports we file or submit to the SEC under the Act is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions to be made regarding required disclosure. Each of Brian W. Christian, our President and Chief Executive Officer and Bradley E. Troutman, our Senior Vice President and Chief Financial Officer, has evaluated the design and effectiveness of our disclosure controls and procedures as of March 31, 2026. Based upon their evaluation, these executive officers have concluded that our disclosure controls and procedures are effective as of the date of such evaluation.

#### Internal control over financial reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting which, as defined by Exchange Act Rule 13a-15(f) means a process designed by, or under the supervision of, our principal executive and principal financial officers, or persons performing similar functions, and effected by the board of directors, management and other personnel, 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, and includes those policies and procedures that:

● Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets,

● Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors, and

● Provide reasonable assurance regarding prevention or timely detection of an unauthorized acquisition, use or disposition of our assets that could have a material effect on our Condensed Consolidated Financial Statements.

#### Changes in internal control over financial reporting
There has been no change to our internal control over financial reporting during the quarter ended March 31, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Analysis by RBT.</u> RBT shall analyze the Official Samples and the results of such analysis for each shipment shall be provided to Buyer not later than thirty (30) days following the date of such shipment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Analysis by Buyer.</u> Buyer may, but shall not be obligated to, analyze the Official Samples. Unless Buyer notifies RBT within [\*\*\*] of receipt of an Official Sample that Buyer's analysis indicates that Product fails to meet Specifications or that the TiO2 content is more than [\*\*\*] different from RBT's analysis, the results of RBT's analysis shall be final and conclusive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Umpire Procedure.</u> Should Buyer's analysis of the Official Sample indicate that Product does not meet Specifications or that the TiO2 content of Product is more than [\*\*\*] different from RBT's analysis, Buyer may so advise RBT and RBT shall request the independent testing laboratory referred to above to forward for analysis its retained Official Sample to such umpire analyst (being an independent testing laboratory) as shall be agreed to from time to time by the parties. The parties hereby agree at this time for this purpose that Inspectorate Griffith Limited, 2 Perry Road, Witham, Essex, CM8 3TU, U.K. shall be the initial umpire analyst. The umpire shall analyze the Official Sample in accordance with the methods outlined in the Exhibits referred to in Article XI.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Settlement.</u> The umpire's analysis as to TiO2 content and that of Buyer or RBT, whichever is in closer agreement, shall be averaged as the basis for final

------

settlement; provided that if the umpire's analysis lies exactly halfway between Buyer's and RBT's analyses, the umpire's analysis shall be the basis for final settlement.

If such final basis for settlement results in a price adjustment in accordance with the procedure described in Article V of this Agreement, RBT shall issue a credit or debit invoice as the case may be. If an umpire's analysis is required on any Specification other than Ti02, the umpire's analysis and that of Buyer or RBT, whichever is in closer agreement, shall be averaged as the basis for final settlement; provided that if the umpire's analysis lies exactly halfway between the Buyer's and RBT's analyses, the umpire's analysis shall be the basis for final settlement. If such analysis determines that Product does not meet each of such Specifications, the parties shall proceed as described in Article IX.B. of this Agreement. The cost of an umpire's analysis shall be paid by the party whose analysis varies most from the umpire's analysis unless such variations are equal and then the cost shall be borne equally by the parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. <u>Revision of Sampling and Analytical Procedures.</u> The procedures set forth in the Exhibits referred to in this article are believed to be the most satisfactory ones now available. However, better procedures may become available. Each of said Exhibits may be revised from time to time, without formal amendment to this Agreement; provided that each such revision shall require the written approval of Buyer and RBT.

**ARTICLE XII. ARBITRATION**

Any dispute between the parties hereto arising out of or in any way connected with this Agreement, its negotiation, performance, breach, existence or validity shall, unless settled by mutual agreement or conciliation and failing settlement thereunder, be referred for final and binding arbitration, in London, England, under the Rules of Conciliation and Arbitration of the International Chamber of Commerce. The arbitration shall be presided over by three arbitrators of which RBT shall appoint one and Buyer shall appoint another, and the two appointed arbitrators shall appoint the Chairman of the arbitral tribunal within thirty (30) days following their appointment by the parties hereto, failing which the Chairman shall be appointed by the International Court of Arbitration of the International Chamber of Commerce. The language of the arbitration and all documents submitted therein shall be in English.

**ARTICLE XIII. TAXES AND DUTIES**

All South African taxes and duties now or hereafter imposed during the term of this Agreement shall be for the sole account of RBT. All taxes and duties now or hereafter imposed on the import of the Product during the term of this Agreement shall be for the sole account of Buyer.

**ARTICLE XIV. PATENTS**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. RBT agrees to protect and hold Buyer harmless against any and all claims that Product in the state or form as sold under this Agreement infringes or allegedly infringes any Product claims of any South African or United States patent owned by third parties. RBT will, at its own cost and expense, defend any and all suits which may be brought against Buyer on account of said infringement of such patent or patents, and RBT shall pay any and all fees, costs and damages awarded in said suits; provided, however, that the total liability for damages under this Article XIV shall in no event exceed the aggregate sales price of Product sold to Buyer during the year in which such infringement commenced.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. RBT's obligations pursuant to Article XIV shall be conditional upon Buyer giving prompt

------

notice to RBT of any claims by third parties of any such alleged infringement and of all information available to Buyer in respect of such alleged infringement or claim.

**ARTICLE XV. FORCE MA.IEURE**

In the event of any contingency which is beyond the reasonable control of RBT or Buyer including, but not limited to (i) any strike, lockout, industrial dispute, difference with workmen, accident, fire, explosion. earthquake, flood, mobilization, war (whether declared or undeclared), act of any belligerent in any such war, civil commotion, political demonstration or disturbance, riot, rebellion, revolution or blockage, (ii) any requirement, regulation, restriction, intervention, or other act of any Government, whether legal or otherwise, (iii) any inability to secure or delay in securing export licenses or import licenses, cargo space or other transportation facilities necessary for the shipment or receipt of Product or fuel or other supplies or material including but not limited to water, ilmenite ore or electric power necessary for the operation of the mines and plants where Product is produced or consumed, (iv) any delay in or interruption to transportation by rail, water or otherwise, (v) any damage to or destruction of such mines or plants or any breakdown of plants or machinery <u>of</u> RBT or Buyer, or (vi) any other contingency which is beyond the reasonable control of RBT or Buyer, whether or not of the nature or character hereinbefore specifically enumerated, but excluding market conditions of any nature, which event delays or interferes with the performance of this Agreement or the consumption of Product, in spite of the affected parties' bona fide efforts to mitigate such event, then such event shall be considered sufficient justification for delay in making shipment or delivery or taking delivery or performance hereunder (other than the payment of money), in whole or in part, until such event ceases to exist, and this Agreement shall be deemed suspended for so long as such event delays or interferes with the performance hereof, provided that prompt notice (normally within one week of the occurrence of the event) of the commencement and end of any such event is given by the party affected to the other party. Any delay or interference which affects RBT' s supply of Product to customers shall entitle RBT to allocate equitably any available Product among customers in its discretion. During the pendency of any Force Majeure declared by RBT, Buyer [\*\*\*] for such year shall be adjusted accordingly.

Anything to the contrary hereinabove notwithstanding, if such event occurs, the obligation of RBT to sell and deliver and of Buyer to buy and to take delivery of Product with respect to any year shall terminate unless otherwise agreed between the parties at the end of the year as to quantities of Product which have not been loaded aboard Buyer's Vessel at Richards Bay, by the end of the year due to such event. Nothing contained in this Article shall require Buyer to pay for, or RBT to make up or compensate for, any Product not delivered due to application of this Article. Either party may terminate the Agreement if such event continues for more than one hundred and eighty (180) days.

**ARTICLE XVI. DEFAULT & LIMITS OF LIABILITY**

For purposes of Article XVI, a "default" shall mean any failure by either party to make any payment when due or to perform any obligation under or pursuant to this Agreement for any reason other than an event of Force Majeure as defined in Article XV.

No default shall be deemed to have occurred unless the party in default shall have first been given written notice of such default and shall have failed to cure such default within thirty (30) days in the event of a failure to pay and in all other events, within sixty (60) days after receipt of such written notice.

In the event of a default arising from a breach of Buyer's duty to pay for Product delivered or for the total quantity of Product to be purchased in any particular year, RBT shall have the right to seek damages for all loss or damage actually sustained as a direct result of the default. In addition, RBT shall have the right (subject to Buyer's right to cure its default pursuant to this

------

Article) to terminate this Agreement forthwith by providing notice to such effect to Buyer. Notwithstanding anything contained herein to the contrary, in no event shall Buyer be liable for consequential, indirect or special damages as a result of a default for failure to pay under this Agreement.

In the event of any default by RBT arising from a failure to deliver Product pursuant to this Agreement, RBT (subject to RBT's rights to cure its default pursuant to this Article) shall compensate Buyer for all loss or damage actually sustained as a direct result of the failure to deliver but excluding indirect, consequential, punitive or contingent damages of the default Buyer may suffer therewith including, but not limited to, loss of revenue or profits as a result of Buyer's inability to operate, or shutdown of its operations, loss of use of equipment, or cost of substitute equipment, claims of third parties, and the like.

**ARTICLE XVII. WAIVER OF DEFAULT**

Any failure by either party to give notice in writing to the other party of any breach or default in any terms or conditions of this Agreement shall not constitute a waiver thereof, nor shall any delay by either party in enforcing any of its rights hereunder be deemed a waiver of such rights nor shall a waiver by either party of any defaults of the other party be deemed a waiver of any other or subsequent defaults.

**ARTICLE XVIII. CONFIDENTIALITY**

This Agreement and information obtained by one party from the other by virtue of this Agreement, shall remain confidential and shall not be disclosed to any third party without the prior written consent of the other party, unless such information is publicly available, or previously known to the recipient or is required to be disclosed by law.

**ARTICLE XX. ASSIGNMENT**

Neither party may assign its rights or obligations under this Agreement without the prior written consent of the other party, which consent shall not be reasonably withheld or delayed. The preceding sentence shall not apply to assignments made to parents, subsidiaries, or related corporations, partnerships or other entities of the parties hereto, providing that the party executing this Agreement shall remain primarily responsible for performance of its obligations hereunder unless such is waived in writing by the other party. Buyer may also assign its rights or obligations under this Agreement without prior written consent of RBT to an unrelated financially capable purchaser of all or essentially of Buyer's TiO2 pigment business, provided that the assignee agrees to assume all of Buyer's duties and obligations hereunder and Buyer agrees to and shall remain secondarily responsible for performance of its obligations hereunder unless such is waived in writing by RBT.

Seller's Obligation to Assign. Notwithstanding the foregoing, in the event Seller sells, transfers, or disposes of all or substantially all of the assets or operations related to the production or supply of the Product (a "Business Transfer"), Seller shall cause the transferee or acquirer of such assets or operations to assume all of Seller's rights and obligations under this Agreement in a writing reasonably satisfactory to Buyer. Failure by Seller to secure such assumption shall constitute a material breach of this Agreement.

Buyer's Termination Right upon Seller Change of Control. In the event of (i) any assignment by Seller, (ii) a Business Transfer, or (iii) a Change of Control of Seller (defined as the acquisition of more than 50% of the voting equity or control of the board of directors of Seller by a third party), Buyer shall have the right, but not the obligation, to terminate this Agreement upon 180-days' prior written notice to Seller or its successor, where such written notice shall be provided not later than 180 days following receipt of written notice of such transaction from Seller. Seller shall provide Buyer with at least 60 days' prior written notice of any such proposed transaction to allow Buyer to evaluate its options.

Notwithstanding anything to the contrary herein, Seller may assign its right to receive payment of monies due or to become due under this Agreement solely in connection with a factoring, securitization, or receivables financing transaction, provided that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. No Delegation of Obligations: Such assignment shall apply only to the right to payment and shall not assign, delegate, novate, or transfer any of Seller's performance obligations or other rights under this Agreement. Seller shall remain fully liable for the performance of all obligations under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Preservation of Buyer's Rights: Any such assignment shall be subject to all of Buyer's rights under this Agreement, including but not limited to rights of set-off, deduction, recoupment, and defenses against payment for non-conforming goods or services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. No Increased Burden: The assignment shall not result in any additional cost, expense, or administrative burden to Buyer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Discharge of Liability: Buyer's payment to the assignee (upon receipt of proper written notice directing such payment) shall fully discharge Buyer's payment obligation to Seller for the applicable amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Notice Requirements: Seller must provide Buyer with at least thirty (30) days' prior written notice of any such assignment, which notice must clearly specify payment instructions.
