The Refining Solutions business that was divested and contributed is defined as the Company’s Ketjen reportable segment, excluding its performance catalysts solutions (“PCS”) business and the Company’s 50% ownership interest in Eurecat S.A. (which the Company divested in a separate transaction as described below). Following the completion of the transactions in the definitive agreement (collectively, the “Refining Solutions Business Transaction”), the Company received $525.2 million in cash, net of cash sold, owned 49% of the common units of Holdco and retained 100% ownership of the PCS business. As a result of the Refining Solutions Business Transaction, the Company recorded a loss of $95.0 million before income taxes in 2026.
The Company’s ownership interest in Holdco, initially representing a 49% interest following completion of the Refining Solutions Business Transaction, consists of common units that are junior to the preferred equity in Holdco held by the other ownership group. The preferred equity accrues dividends, regardless of whether or not declared, for the first five years after the closing of the Refining Solutions Business Transaction, and is convertible into common equity of Holdco at the option of the holder.
In a separate transaction, on January 23, 2026, the Company completed the sale of its 50% ownership interest in Eurecat S.A., a joint venture included in the Refining Solutions reporting unit, for €105 million (approximately $123 million using foreign exchange rates on the closing date) in cash, to Axens SA and recorded a gain before income taxes of $42.3 million in Other income (expenses), net on the consolidated statements of income during the six-month period ended June 30, 2026.
In connection with the Company’s entry into the definitive agreement related to the Refining Solutions Business Transaction, on October 25, 2025, the Company concluded the Refining Solutions business met the criteria to be classified as held for sale in the Company’s consolidated financial statements. As such, the assets and liabilities of the Refining Solutions business were included in the current or noncurrent assets held for sale and liabilities held for sale, respectively, in the consolidated balance sheet at December 31, 2025. The Eurecat S.A. transaction was separate from the Refining Solutions Business Transaction, and its investment was not classified as held for sale. Upon classification as held for sale, the Refining Solutions business was measured at the lower of its carrying amount or its fair value less costs to sell.
The carrying amounts of the major classes of assets and liabilities that were classified as held for sale at December 31, 2025 were as follows (in thousands):

Total liabilities held for sale$251,723 

(a)    Does not include the Company’s Eurecat investment of $81.9 million, which was not part of the Refining Solutions business transaction or classified as held for sale.
Neither the Refining Solutions business nor the investment in Eurecat S.A. qualified for discontinued operations treatment at December 31, 2025 because the Company’s management did not consider these sales as representing a strategic shift that had or will have a major effect on the Company’s operations and financial results.

The Company purchases certain of its inventory from its equity method investments (primarily the Windfield Holdings Pty. Ltd. (“Windfield”) joint venture) and eliminates the balance of intra-entity profits on purchases of such inventory that remains unsold at the balance sheet date in Inventories, specifically finished goods, and equally reduces Equity in net income of unconsolidated investments (net of tax) on the consolidated statements of income. The balance of intra-entity profits on inventory purchased from equity method investments in Inventories totaled $143.0 million and $37.2 million at June 30, 2026 and December 31, 2025, respectively. The intra-entity profit is recognized in Equity in net income of unconsolidated
investments (net of tax) in the period that converted inventory is sold to a third-party customer. In the same period, the intra-entity profit is also recognized as higher Cost of goods sold on the consolidated statements of income.

Equity Method Investments and Joint Ventures [Abstract]  
Investments Investments:
Unconsolidated Joint Ventures
Following the completion of the Refining Solutions Business Transaction discussed in Note 2, “Divestitures,” the Company retained an initial 49% ownership interest in the Ketjen joint venture. The Company’s valuation of its investment in this Ketjen joint venture was measured using the Black-Scholes option-pricing model using key assumptions such as equity volatility, a risk-free rate and certain terms of the joint venture agreement. This nonrecurring fair value measurement is classified as Level 3 within the fair value hierarchy due to the unobservable inputs used. The Company’s investment in this unconsolidated joint venture is reported within Investments on the consolidated balance sheet, and its equity in net income of unconsolidated investments (net of tax) is included within Other joint ventures in the below table. In addition, the Company divested all of its direct ownership interests in Nippon Ketjen Company Limited and Fábrica Carioca de Catalisadores S.A., joint ventures included in the Refining Solutions Business Transaction. The investment balances for these unconsolidated investments were reported within Noncurrent assets held for sale at December 31, 2025.
In a separate transaction, on January 23, 2026, the Company divested its 50% ownership interest in the Eurecat S.A joint venture and recorded a gain of $42.3 million in Other income (expenses), net on the consolidated statements of income during the six-month period ended June 30, 2026.
The following table details the Company’s equity in net income of unconsolidated investments (net of tax) for the three-month and six-month periods ended June 30, 2026 and 2025 (in thousands):

The Company holds a 49% equity interest in Windfield, where the ownership parties share risks and benefits disproportionate to their voting interests. As a result, the Company considers Windfield to be a variable interest entity (“VIE”), however this investment is not consolidated as the Company is not the primary beneficiary. The carrying amount of the Company’s 49% equity interest in Windfield, which is the Company’s most significant VIE, was $985.0 million and $735.3 million at June 30, 2026 and December 31, 2025, respectively. The Company’s unconsolidated VIEs are reported in Investments on the consolidated balance sheets. The Company does not guarantee debt for, or have other financial support obligations to, these entities, and its maximum exposure to loss in connection with its continuing involvement with these entities is limited to the carrying value of the investments.
The following table summarizes the unaudited results of operations for the Windfield joint venture, which met the significant subsidiary test for subsidiaries not consolidated or 50% or less owned persons under Rule 10-01 of Regulation S-X, for the three-month and six-month periods ended June 30, 2026 and 2025 (in thousands):

As a result, included in Interest and financing expenses for the six-month period ended June 30, 2026 is a gain on early extinguishment of debt of $12.5 million, representing the repurchase of these notes at a discount, partially offset by tender premiums and redemption fees.
Accounts Receivable Purchase Agreements
We are party to master receivables purchase agreements, under which we may sell available and eligible outstanding customer accounts receivable generated by sales to certain customers of up to approximately $249 million at any one time. The agreements are uncommitted and can be terminated by us or the purchaser upon notice in accordance with the terms of the agreements. Transactions under these agreements are accounted for as sales of accounts receivable, and the receivables sold are removed from the consolidated balance sheets as of the effective time of the sales transaction. During the three-month and six-month periods ended June 30, 2026, the Company sold and removed approximately $281.6 million and $516.7 million, respectively, of accounts receivable under the master receivables purchase agreements. The Company incurred approximately $1.9 million and $3.5 million, respectively, of fees associated with the master receivables purchase agreements during the three-month and six-month periods ended June 30, 2026. Costs associated with the sales of receivables are reflected in the consolidated statements of income for the periods in which the sales occur.

Amounts reported in Other noncurrent liabilities$16,543 
Environmental remediation liabilities included discounted liabilities of $17.1 million and $17.0 million at June 30, 2026 and December 31, 2025, respectively, discounted at rates with a weighted-average of 4.0%, and with the undiscounted amount totaling $33.9 million and $34.2 million at June 30, 2026 and December 31, 2025, respectively.
The amounts recorded represent our future remediation and other anticipated environmental liabilities. These liabilities typically arise during the normal course of our operational and environmental management activities or at the time of acquisition of a site, and are based on internal analysis as well as input from outside consultants. As evaluations proceed at each relevant site, changes in risk assessment practices, remediation techniques and regulatory requirements can occur, therefore such liability estimates may be adjusted accordingly. The timing and duration of remediation activities at these sites will be determined when evaluations are completed. Although it is difficult to quantify the potential financial impact of these remediation liabilities, management estimates (based on the latest available information) that there is a reasonable possibility that future environmental remediation costs associated with our past operations could represent an additional $38 million before income taxes, in excess of amounts already recorded.
We believe that any sum we may be required to pay in connection with environmental remediation matters in excess of the amounts recorded would likely occur over a period of time and would likely not have a material adverse effect upon our results of operations, financial condition or cash flows on a consolidated annual basis although any such sum could have a material adverse impact on our results of operations, financial condition or cash flows in a particular quarterly reporting period.
Litigation
We are involved from time to time in legal proceedings of types regarded as common in our business, including administrative or judicial proceedings seeking remediation under environmental laws, such as the federal Comprehensive Environmental Response, Compensation and Liability Act, commonly known as CERCLA or Superfund, products liability, breach of contract liability and premises liability litigation. Where appropriate, we may establish financial reserves for such proceedings. We also maintain insurance to mitigate certain of such risks. Costs for legal services are generally expensed as incurred.
Indemnities
We are indemnified by third parties in connection with certain matters related to acquired and divested businesses. Although we believe that the financial condition of those parties that may have indemnification obligations to the Company is generally sound, in the event the Company seeks indemnity under any of these agreements or through other means, there can be no assurance that any party that may have obligations to indemnify us will adhere to their obligations and we may have to resort to legal action to enforce our rights under the indemnities.
The Company may be subject to indemnity claims relating to properties or businesses it divested, including properties or businesses of acquired businesses that were divested prior to the completion of the acquisition. In the opinion of management, and based upon information currently available, the ultimate resolution of any indemnification obligations owed to the Company or by the Company is not expected to have a material effect on the Company’s financial condition, results of operations or cash flows. The Company had approximately $17.5 million and $12.1 million at June 30, 2026 and December 31, 2025, respectively, recorded in Other noncurrent liabilities, primarily related to the indemnification of certain income and non-income tax liabilities associated with the Chemetall Surface Treatment entities sold in 2016 and the Refining Solutions Business Transaction in March 2026.
Other
The Company has contracts with certain of its customers which serve as guarantees of product delivery and performance according to customer specifications that can cover both shipments on an individual basis, as well as blanket coverage of multiple shipments under certain customer supply contracts. The financial coverage provided by these guarantees is typically based on a percentage of net sales value. The Company is unable to estimate the maximum amount of the potential future liability under performance guarantees. However, the Company accrues for any potential loss for which we believe a future payment is probable and a range of loss can be reasonably estimated. At June 30, 2026, the Company believes its liability under such obligations is immaterial.

Restructuring and Related Activities [Abstract]  
Restructuring Charges and Asset Write-Offs Restructuring Charges and Asset Write-offs:
Kemerton Train 1 Restructuring
In February 2026, in connection with the Company’s ongoing review of its cost and operating structure, the Company put the Kemerton Train 1 in Western Australia into care and maintenance. Since February 2026, the Company recorded charges in Restructuring charges and asset write-offs of $31.8 million, consisting of decommissioning costs, asset disposal costs, contract cancellation costs, severance and other associated charges resulting from placing Kemerton Train 1 into care and maintenance (the “Kemerton Train 1 Restructuring”). All charges related to the Kemerton Train 1 Restructuring were recorded in the Energy Storage segment.
In connection with the Kemerton Train 1 Restructuring, the Company expects to record additional charges in the range of $70 million to $90 million, primarily related to decommissioning costs during the remainder of 2026 and 2027, when the actions are expected to be completed.
Second Half 2024 Restructuring
In July 2024, the Company announced a comprehensive review of its cost and operating structure to proactively respond to ongoing industry headwinds, particularly in the lithium value chain, and to maintain a competitive position (the “Second Half 2024 Restructuring”). As part of this review, the Company made the decision to stop construction of Kemerton Train 3 in Western Australia, and put Kemerton Train 2 into care and maintenance, as the Company determined the current lithium price environment makes it less economical to expand conversion in Australia. Additionally, as part of this restructuring plan, the Company placed the Chengdu, China conversion plant into care and maintenance during the first half of 2025. Production from the Chengdu site has been transferred to another processing facility in China.
The Company’s actions regarding Kemerton were part of a broader effort focused on preserving its world-class resource advantages, optimizing its global conversion network, improving the Company’s cost competitiveness and efficiency by lowering operating costs, reducing capital intensity and enhancing the Company’s financial flexibility. As part of this overall effort, the Company also implemented a global workforce reduction that impacted 6-7% of total headcount during the second half of 2024.
Since July 2024, the Company has recorded charges for this plan consisting of decommissioning costs of $13.2 million, asset write-offs of $726.0 million, severance and employee benefits of $53.4 million, contract cancellation costs of $38.4 million and other (primarily consisting of the reclassification of the related dedesignated cash flow hedge from Accumulated other comprehensive loss) of $29.3 million. Charges related to Second Half 2024 Restructuring were primarily recorded in the Energy Storage segment, with the exception of severance and employee benefits, which were recorded globally in Corporate and all segments. The Company finalized placing Kemerton Train 2 into care and maintenance during the first half of 2026.

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes:
The effective income tax rate for the three-month and six-month periods ended June 30, 2026 were 21.3% and 16.6%, respectively, compared to (380.0)% and (107.8)% for the three-month and six-month periods ended June 30, 2025, respectively. The Company’s effective income tax rate fluctuates based on, among other factors, the amount and location of income. The change in effective tax rate in the three-month and six-month periods ended June 30, 2026, compared to the three-month and six-month periods ended June 30, 2025, was due to the impact of 2026 earnings in various jurisdictions, including the impact of valuation allowances. The difference between the U.S. federal statutory income tax rate of 21% and the Company’s effective income tax rate for the three-month and six-month periods ended June 30, 2026 was due to the net impact of the location in which income was earned, including the impact of valuation allowances for losses in the Company’s consolidated U.S. entities, Australian entities and certain entities in China. The difference between the U.S. federal statutory income tax rate of 21% and the Company’s effective income tax rate for the three-month and six-month periods ended June 30, 2025 was due to the net impact of the location in which income was earned, including the impact of valuation allowances for losses in our consolidated Australian entities and certain entities in China.

Leases Leases:
We lease certain office space, buildings, transportation and equipment in various countries. The initial lease terms generally range from 1 to 30 years for real estate leases, and from 2 to 15 years for non-real estate leases. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and we recognize lease expense for these leases on a straight-line basis over the lease term.
Many leases include options to terminate or renew, with renewal terms that can extend the lease term from 1 to 50 years or more. The exercise of lease renewal options is at our sole discretion. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there
is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Fair Value Disclosures [Abstract]  
Fair Value of Financial Instruments Fair Value of Financial Instruments:
In assessing the fair value of financial instruments, the Company uses methods and assumptions that are based on market conditions and other risk factors existing at the time of assessment. Fair value information for the Company’s financial instruments is as follows:
Long-Term Debt—the fair values of the Company’s notes are estimated using Level 1 inputs and account for the difference between the recorded amount and fair value of our long-term debt. The carrying value of the Company’s remaining long-term debt reported in the accompanying consolidated balance sheets approximates fair value as substantially all of such debt bears interest based on prevailing variable market rates currently available in the countries in which we have borrowings.

Foreign Currency Forward Contracts—In connection with our risk management strategies, we enter into derivative financial instruments that have not been designated as hedging instruments under ASC 815, Derivatives and Hedging. These derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. At June 30, 2026 and December 31, 2025, we had outstanding non-designated derivative financial instruments with notional values totaling $1.4 billion and $2.4 billion, respectively. The non-designated derivative financial instruments are primarily comprised of foreign currency forward contracts that attempt to minimize the financial impact of changes in foreign currency exchange rates. The fair values of our non-designated foreign currency forward contracts are estimated based on current settlement values. At June 30, 2026, these foreign currency forward contracts hedge our exposure to various currencies including the Chinese Renminbi, Euro and Australian Dollar.
Net Investment Hedge—In June 2026, the Company entered into cross currency swaps with an aggregate notional amount of €1 billion to minimize the financial impact of changes in foreign currency exchange rates between the U.S. Dollar and Euro. These derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. These cross currency swaps qualify and have been designated as an effective net investment hedge of the Company's foreign currency exchange rate exposure of the net investments in foreign subsidiaries where the Euro serves as the functional currency. The Company will account for the net investment hedge using the spot method. Gains or losses on the revaluation of these cross currency swaps to our reporting currency are recorded in Accumulated other comprehensive loss. Excluded components are amortized as interest income, within Other income (expenses), net on the consolidated statements of income, as that interest is accrued.

In addition, for the six-month periods ended June 30, 2026 and 2025, we recorded net cash (settlements) receipts of ($18.8) million and $161.9 million, respectively, in (Payments) proceeds from settlement of foreign currency forward contracts, net, in our condensed consolidated statements of cash flows.
The counterparties to our foreign currency forward contracts are major financial institutions with which we generally have other financial relationships. We are exposed to credit loss in the event of nonperformance by these counterparties. However, we do not anticipate nonperformance by the counterparties.

Fair Value Disclosures [Abstract]  
Fair Value Measurement Fair Value Measurement:
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The inputs used to measure fair value are classified into the following hierarchy:
Level 1Unadjusted quoted prices in active markets for identical assets or liabilities
Level 2Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability
Level 3Unobservable inputs for the asset or liability
We endeavor to utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2026 and December 31, 2025 (in thousands):

(a)We have maintained an Executive Deferred Compensation Plan (“EDCP”) since 2001. The purpose of the EDCP is to provide current tax planning opportunities as well as supplemental funds upon the retirement or death of certain of our employees. The EDCP is intended to aid in attracting and retaining employees of exceptional ability by providing them with these benefits. We also maintain a Benefit Protection Trust (the “Trust”) that was created to provide a source of funds to assist in meeting the obligations of the EDCP, subject to the claims of our creditors in the event of our insolvency. Assets of the Trust are consolidated in accordance with authoritative guidance. The assets of the Trust consist primarily of mutual fund investments (which are accounted for as trading securities and are marked-to-market on a monthly basis through the consolidated statements of income) and cash and cash equivalents. As such, these assets and obligations are classified within Level 1.
(b)Holdings in equity securities of public companies is reported in Investments in the consolidated balance sheets. The fair value is measured using publicly available share prices of the investments, and as a result these balances are classified within Level 1. Any changes are reported in Other income (expenses), net in our consolidated statements of income. See Note 4, “Investments,” for further details.
(c)The Company’s private equity security investments are measured at fair value using the net asset value per share (or its equivalent) practical expedient and have not been categorized in the fair value hierarchy. Private equity securities are reported in Investments in the consolidated balance sheets and changes in fair value are reported in Other income (expenses), net in the consolidated statements of income.
(d)Derivative financial instruments are primarily comprised of the net investment hedge and foreign currency forward contracts. As a result of the Company’s global operating and financing activities, it is exposed to market risks from changes in foreign currency exchange rates which may adversely affect its operating results and financial position. When deemed appropriate, the Company minimizes its risks from foreign currency exchange rate fluctuations through the use of foreign currency forward contracts and the net investment hedge. The foreign currency forward contracts and net investment hedge are valued using broker quotations or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are classified within Level 2. See Note 15, “Fair Value of Financial Instruments,” for further details about the Company’s derivative financial instruments.

Segment Reporting [Abstract]  
Segment Information Segment Information:
Following the completion of the sale of our Refining Solutions business discussed in Note 2, “Divestitures,” the Company has two reportable segments: (1) Energy Storage and (2) Specialties. The segments are organized based on their similar markets, customers, economic characteristics and production processes. The organizational structure facilitates the continued standardization of business processes across the organization, and is consistent with the manner in which information is presently used internally by the Company’s Chairman, President and Chief Executive Officer, who is the Company’s chief operating decision maker (“CODM”), to evaluate performance and make resource allocation decisions.
The Corporate and All Other category is not considered to be a segment and includes corporate-related items not allocated to the operating segments, as well as the results of the PCS business and the ownership interest in the Ketjen joint venture, as they do not fit into any of our core businesses. Pension and other post-employment benefit (“OPEB”) service cost (which represents the benefits earned by active employees during the period) and amortization of prior service cost or benefit are allocated to the reportable segments and Corporate, whereas the remaining components of pension and OPEB benefits cost or credit (“non-operating pension and OPEB items”) are included in Corporate. Segment data includes inter-segment transfers of raw materials at cost and allocations for certain corporate costs.
The CODM uses adjusted EBITDA (as defined below) to assess the ongoing performance of the Company’s business segments and to allocate resources by considering the variance in the actual results to the forecasts on a monthly basis. The annual operating budget and ongoing forecasting process use adjusted EBITDA as a key metric in assessing the segments’ performance. In addition, the CODM uses adjusted EBITDA for business and enterprise planning purposes and as a significant component in the calculation of performance-based compensation for management and other employees. The Company’s definition of adjusted EBITDA is earnings before interest and financing expenses, income tax expenses, the proportionate share of Windfield income tax expense, depreciation and amortization, as adjusted on a consistent basis for certain non-operating, non-recurring or unusual items on a segment basis. These non-operating, non-recurring or unusual items may include acquisition and integration related costs, gains or losses on sales of businesses, restructuring charges and asset write-offs, facility divestiture charges, certain litigation and arbitration costs and charges, non-operating pension and OPEB items and other significant non-recurring items. This calculation is consistent with the definition of adjusted EBITDA used in the leverage financial covenant calculation in the Company’s credit agreement, which is a material agreement for the Company and aligns the information presented to various stakeholders. Prior period amounts have been recast to reflect the current segment structure.
See below for a reconciliation of segment Net sales to adjusted EBITDA by segment showing significant segment expenses regularly provided to the CODM for the three-month and six-month periods ended June 30, 2026 and 2025 (in thousands):

(a)We have maintained an Executive Deferred Compensation Plan (“EDCP”) since 2001. The purpose of the EDCP is to provide current tax planning opportunities as well as supplemental funds upon the retirement or death of certain of our employees. The EDCP is intended to aid in attracting and retaining employees of exceptional ability by providing them with these benefits. We also maintain a Benefit Protection Trust (the “Trust”) that was created to provide a source of funds to assist in meeting the obligations of the EDCP, subject to the claims of our creditors in the event of our insolvency. Assets of the Trust are consolidated in accordance with authoritative guidance. The assets of the Trust consist primarily of mutual fund investments (which are accounted for as trading securities and are marked-to-market on a monthly basis through the consolidated statements of income) and cash and cash equivalents. As such, these assets and obligations are classified within Level 1.
(b)Holdings in equity securities of public companies is reported in Investments in the consolidated balance sheets. The fair value is measured using publicly available share prices of the investments, and as a result these balances are classified within Level 1. Any changes are reported in Other income (expenses), net in our consolidated statements of income. See Note 4, “Investments,” for further details.
(c)The Company’s private equity security investments are measured at fair value using the net asset value per share (or its equivalent) practical expedient and have not been categorized in the fair value hierarchy. Private equity securities are reported in Investments in the consolidated balance sheets and changes in fair value are reported in Other income (expenses), net in the consolidated statements of income.
(d)Derivative financial instruments are primarily comprised of the net investment hedge and foreign currency forward contracts. As a result of the Company’s global operating and financing activities, it is exposed to market risks from changes in foreign currency exchange rates which may adversely affect its operating results and financial position. When deemed appropriate, the Company minimizes its risks from foreign currency exchange rate fluctuations through the use of foreign currency forward contracts and the net investment hedge. The foreign currency forward contracts and net investment hedge are valued using broker quotations or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are classified within Level 2. See Note 15, “Fair Value of Financial Instruments,” for further details about the Company’s derivative financial instruments.
