Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies: Basis of Consolidation The consolidated financial statements include the accounts and operations of Albemarle Corporation and our wholly owned, majority owned and controlled subsidiaries. Unless the context otherwise indicates, the terms “Albemarle,” “we,” “us,” “our” or “the Company” mean Albemarle Corporation and its consolidated subsidiaries. For entities that we control and are the primary beneficiary, but own less than 100%, we record the minority ownership as noncontrolling interest, except as noted below. We apply the equity method of accounting for investments in which we have an ownership interest from 20% to 50% or where we exercise significant influence over the related investee’s operations. In addition, the consolidated financial statements contained herein include our proportionate share of the results of operations of the MARBL Lithium Joint Venture (“MARBL”), which manages the exploration, development, mining, processing and production of lithium and other minerals from the Wodgina hard rock lithium mine project (“Wodgina”). As described in Note 8, “Investments,” the Company closed on the restructuring of the MARBL joint venture with Mineral Resources Limited (“MRL”) on October 18, 2023 to reduce our ownership interest in the MARBL joint venture to 50% from 60%. The consolidated financial statements reflect our ownership percentage of the MARBL joint venture during the periods presented. The joint venture is unincorporated with each investor holding an undivided interest in each asset and proportionately liable for each liability; therefore our proportionate share of assets, liabilities, revenue and expenses are included in the appropriate classifications in the consolidated financial statements. All significant intercompany accounts and transactions are eliminated in consolidation. Cost of goods sold for the year ended December 31, 2024 includes income of $17.4 million for the correction of out of period errors pertaining to an overstated accrual for a profit sharing arrangement with the partner of one of the Company’s joint ventures. For the year ended December 31, 2023, Cost of goods sold was overstated by $17.4 million. The Company believes this adjustment is not material to the consolidated financial statements for the prior period presented, or for the current periodd, in which the correction was made. Estimates, Assumptions and Reclassifications The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) requires management to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Revenue Recognition Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods and is recognized when performance obligations are satisfied under the terms of contracts with our customers. A performance obligation is deemed to be satisfied when control of the product is transferred to our customer. The transaction price of a contract, or the amount we expect to receive upon satisfaction of all performance obligations, is determined by reference to the contract’s terms and includes adjustments, if applicable, for any variable consideration, such as customer rebates, noncash consideration or consideration payable to the customer, although these adjustments are generally not material. Where a contract contains more than one distinct performance obligation, the transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation, although these situations are rare and are generally not built into our contracts. Any unsatisfied performance obligations are not material. Standalone selling prices are based on prices we charge to our customers, which in some cases are based on established market prices. Sales and other similar taxes collected from customers on behalf of third parties are excluded from revenue. Our payment terms are generally between 30 to 90 days, however, they vary by market factors, such as customer size, creditworthiness, geography and competitive environment. All of our revenue is derived from contracts with customers, and almost all of our contracts with customers contain one performance obligation for the transfer of goods where such performance obligation is satisfied at a point in time. Control of a product is deemed to be transferred to the customer upon shipment or delivery. Significant portions of our sales are sold free on board shipping point or on an equivalent basis, while delivery terms of other transactions are based upon specific contractual arrangements. Our standard terms of delivery are generally included in our contracts of sale, order confirmation documents and invoices, while the timing between shipment and delivery generally ranges between 1 and 45 days. Costs for shipping and handling activities, whether performed before or after the customer obtains control of the goods, are accounted for as fulfillment costs. Such costs are immaterial. The Company currently utilizes the following practical expedients, as permitted by Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers : • All sales and other pass-through taxes are excluded from contract value; • In utilizing the modified retrospective transition method, no adjustment was necessary for contracts that did not cross over the reporting year; • We will not consider the possibility of a contract having a significant financing component (which would effectively attribute a portion of the sales price to interest income) unless, if at contract inception, the expected payment terms (from time of delivery or other relevant criterion) are more than one year; • If our right to customer payment is directly related to the value of our completed performance, we recognize revenue consistent with the invoicing right; and • We expense as incurred all costs of obtaining a contract incremental to any costs/compensation attributable to individual product sales/shipments for contracts where the amortization period for such costs would otherwise be one year or less. Costs incurred to obtain contracts with customers are not significant and are expensed immediately as the amortization period would be one year or less. When the Company incurs pre-production or other fulfillment costs in connection with an existing or specific anticipated contract and such costs are recoverable through margin or explicitly reimbursable, such costs are capitalized and amortized to Cost of goods sold on a systematic basis that is consistent with the pattern of transfer to the customer of the goods or services to which the asset relates, which is less than one year. We record bad debt expense in specific situations when we determine the customer is unable to meet its financial obligation. Included in Trade accounts receivable at December 31, 2024 and 2023 is approximately $705.8 million and $1.2 billion, respectively, arising from contracts with customers. The remaining balance of Trade accounts receivable at December 31, 2024 and 2023 primarily includes value-added taxes collected from customers on behalf of various taxing authorities. Cash and Cash Equivalents Cash and cash equivalents include cash and money market investments with insignificant interest rate risks and no limitations on access. Inventories Inventories are stated at lower of cost and net realizable value with cost determined using standard cost, which approximates the first-in, first-out basis. Cost is determined on the weighted-average basis for a small portion of our inventories at foreign plants and our stores, supplies and other inventory. A portion of our domestic produced finished goods and raw materials are determined on the last-in, first-out basis. The Company eliminates the balance of intra-entity profits on purchases of inventory from its equity method investments that remains unsold at the balance sheet in Inventories, specifically finished goods and equally reduces Equity in net income of unconsolidated investments (net of tax) on the consolidated statements of (loss) income. 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 (loss) income. Property, Plant and Equipment Property, plant and equipment include costs of assets constructed, purchased or leased under a finance lease, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for normal repairs and maintenance are expensed as incurred. Costs associated with yearly planned major maintenance are generally deferred and amortized over 12 months or until the same major maintenance activities must be repeated, whichever is shorter. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in income. We assign the useful lives of our property, plant and equipment based upon our internal engineering estimates, which are reviewed periodically. The estimated useful lives of our property, plant and equipment range from two We evaluate the recovery of our property, plant and equipment annually and when events or changes in circumstances indicate that its carrying amount may not be recoverable. Events that may trigger a test for recoverability include, but are not limited to, significant adverse changes to projected revenues, costs, or capital plans or changes to government regulations that may adversely impact our current or future operations. An impairment is determined to exist if the total projected future cash flows on an undiscounted basis are not recoverable or are less than the carrying amount of a long-lived asset group. We estimate future cash flows based on numerous assumptions, which are consistent or reasonable in relation to internal budgets and projections, and actual future cash flows may be significantly different than the estimates. Significant estimates used include, but are not limited to, market pricing (including lithium index pricing), customer demand, operating and production costs, and the timing and capital costs of expansion and sustaining projects. Significant management judgment is involved in estimating these variables and they include inherent uncertainties since they are forecasting future events. Leases We determine if an arrangement is a lease at inception. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As an implicit rate for most of our leases is not determinable, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease payments for the initial measurement of lease ROU assets and lease liabilities include fixed and variable payments based on an index or a rate. Variable lease payments that are not index or rate based are recorded as expenses when incurred. Our variable lease payments typically include real estate taxes, insurance costs and common-area maintenance. The operating lease ROU asset also includes any lease payments made, net of lease incentives. The lease term is the non-cancelable period of the lease, including any options to extend, purchase or terminate the lease when it is reasonably certain that we will exercise that option. We amortize the operating lease ROU assets on a straight-line basis over the period of the lease and the finance lease ROU assets on a straight-line basis over the shorter of their estimated useful lives or the lease terms. 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. Additionally, we have made accounting policy elections such as exclusion of short-term leases (leases with a term of 12 months or less and which do not include a purchase option that we are reasonably certain to exercise) from the balance sheet presentation, use of portfolio approach in determination of discount rate and accounting for non-lease components in a contract as part of a single lease component for all asset classes, except specific mining operation equipment. Resource Development Expenses We incur costs in resource exploration, evaluation and development during the different phases of our resource development projects. Exploration costs incurred before the declaration of proven and probable resources are generally expensed as incurred. After proven and probable resources are declared, exploration, evaluation and development costs necessary to bring the property to commercial capacity or increase the capacity or useful life are capitalized. Any costs to maintain the production capacity in a property under production are expensed as incurred. Capitalized resource costs are depleted using the units-of-production method. Our resource development assets are evaluated for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. Investments Investments are accounted for using the equity method of accounting if the investment gives us the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of the investee between 20% and 50%, although other factors, such as representation on the investee’s board of directors and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting, we record our investments in equity-method investees in the consolidated balance sheets as Investments and our share of investees’ earnings or losses together with other-than-temporary impairments in value as Equity in net income of unconsolidated investments in the consolidated statements of (loss) income. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. Certain investments in equity securities and mutual fund investments are accounted for as trading equities and are marked-to-market on a periodic basis through the consolidated statements of (loss) income. Investments in joint ventures and nonmarketable securities of immaterial entities are estimated based upon the overall performance of the entity where financial results are not available on a timely basis. Environmental Compliance and Remediation Environmental compliance costs include the cost of purchasing and/or constructing assets to prevent, limit and/or control pollution or to monitor the environmental status at various locations. These costs are capitalized and depreciated based on estimated useful lives. Environmental compliance costs also include maintenance and operating costs with respect to pollution prevention and control facilities and other administrative costs. Such operating costs are expensed as incurred. Environmental remediation costs of facilities used in current operations are generally immaterial and are expensed as incurred. We accrue for environmental remediation costs and post-remediation costs that relate to existing conditions caused by past operations at facilities or off-plant disposal sites in the accounting period in which responsibility is established and when the related liability is considered probable and estimable. In developing these cost estimates, we evaluate currently available facts regarding each site, with consideration given to existing technology, presently enacted laws and regulations, prior experience in remediation of contaminated sites, the financial capability of other potentially responsible parties and other factors, subject to uncertainties inherent in the estimation process. If the amount and timing of the cash payments for a site are fixed or reliably determinable, the liability is discounted, if the calculated discount is material. Additionally, these estimates are reviewed periodically, with adjustments to the accruals recorded as necessary. Research and Development Expenses Our research and development expenses related to present and future products are expensed as incurred. These expenses consist primarily of personnel-related costs and other overheads, as well as outside service and consulting costs incurred for specific programs. Our U.S. facilities in Texas and Louisiana and our global facilities in the Netherlands, Germany, Belgium and Korea form the capability base for our contract research and custom manufacturing businesses. These business areas provide research and scale-up services primarily to innovative life science companies. Goodwill and Other Intangible Assets We account for goodwill and other intangibles acquired in a business combination in conformity with current accounting guidance that requires that goodwill and indefinite-lived intangible assets not be amortized. We test goodwill for impairment by comparing the estimated fair value of our reporting units to the related carrying value. Our reporting units are either our operating business segments or one level below our operating business segments for which discrete financial information is available and for which operating results are regularly reviewed by the business management. In applying the goodwill impairment test, the Company initially performs a qualitative test (“Step 0”), where it first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting units is less than its carrying value. Qualitative factors may include, but are not limited to, economic conditions, industry and market considerations, cost factors, overall financial performance of the reporting units and other entity and reporting unit specific events. If after assessing these qualitative factors, the Company determines it is “more-likely-than-not” that the fair value of the reporting unit is less than the carrying value, the Company performs a quantitative test (“Step 1”). During Step 1, the Company estimates the fair value using either a discounted cash flow model (income) approach or a combination of the discounted cash flow model (income) approach and earnings multiple (market) approach (placing equal weighting on the income and market approaches). The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to the projected earnings of the reporting unit. Future cash flows for all reporting units include assumptions about revenue growth rates, adjusted EBITDA margins, discount rate as well as other economic or industry-related factors. The Company defines adjusted EBITDA as 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. For the Refining Solutions reporting unit, within the Ketjen segment, the revenue growth rates, adjusted EBITDA margins, EBITDA multiples, market participant acquisition premium and the discount rate were deemed to be significant assumptions. For the Energy Storage reporting unit, the revenue growth rates, adjusted EBITDA margins and the discount rate were deemed to be significant assumptions. Significant management judgment is involved in estimating these variables and they include inherent uncertainties, particularly regarding future market conditions and cost fluctuations. Any adverse changes in these assumptions, such as a decline in demand, increased competition, rising costs or the imposition of new tariffs could negatively impact the fair value of the reporting units, since they are forecasting future events. The Company uses a Weighted Average Cost of Capital (“WACC”) approach to determine our discount rate for goodwill recoverability testing. The WACC calculation incorporates industry-weighted average returns on debt and equity from a market perspective. The factors in this calculation are largely external to the Company and, therefore, are beyond its control. The Company performs a sensitivity analysis by using a range of inputs to confirm the reasonableness of these estimates being used in the goodwill impairment analysis. The Company tests its recorded goodwill for impairment in the fourth quarter of each year or upon the occurrence of events or changes in circumstances that would more likely than not reduce the fair value of its reporting units below their carrying amounts. In July 2024, the Company made the decision to stop construction of Kemerton conversion plant Train 3 and put Kemerton Train 2 into care and maintenance. See Note 17, “Restructuring Charges and Asset Write-offs,” for further details. The Company determined these actions to be a triggering event for a review for impairment of its Energy Storage reporting unit goodwill. As a result, during the third quarter of 2024, the Company tested the goodwill of the Energy Storage reporting unit by comparing its estimated fair value, using a discounted cash flow model, to the related carrying value. Based on the analysis, the Energy Storage reporting unit had sufficient headroom, which is defined as the percentage difference between the fair value of a reporting unit and its carrying value, that reasonable differences in the significant assumptions used would not impact the conclusion. Consequently, the Company concluded that the Energy Storage estimated fair value exceeded its carrying value, thus no impairment was recorded in the third quarter of 2024. The Company performed its annual goodwill impairment test as of October 31, 2024. No evidence of impairment was noted for the reporting units with goodwill balances from the analysis. In addition, there were no triggering events subsequent to the annual goodwill impairment test for any of the reporting units. However, if the adjusted EBITDA or discount rate estimates for the Refining Solutions reporting unit negatively changed by 10% (absent any other changes), the Refining Solutions fair value would be below its carrying value. Potential events and changes in circumstances that could reasonably be expected to negatively affect the key assumptions include reductions in demand in oilfield markets, inability to implement effective pricing actions to offset cost increases, changes in macroeconomic conditions and the introduction or escalation of tariffs on imported materials. The Company will continue to monitor these factors closely and assess their impact on its goodwill impairment evaluations in future periods. The Company assesses its indefinite-lived intangible assets, which include trade names and trademarks, for impairment annually and between annual tests if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. The indefinite-lived intangible asset impairment standard allows the Company to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if we determine, based on the qualitative assessment, that it is more likely than not that the indefinite-lived intangible asset’s fair value is less than its carrying amount. If we determine based on the qualitative assessment that it is more likely than not that the asset is impaired, an impairment test is performed by comparing the fair value of the indefinite-lived intangible asset to its carrying amount. During the year ended December 31, 2024, no evidence of impairment was noted from the analysis for the Company’s indefinite-lived intangible assets. Definite-lived intangible assets, such as purchased technology, patents and customer lists, are amortized over their estimated useful lives generally for periods ranging from five Pension Plans and Other Postretirement Benefits Under authoritative accounting standards, assumptions are made regarding the valuation of benefit obligations and the performance of plan assets. As required, we recognize a balance sheet asset or liability for each of our pension and other postretirement benefit (“OPEB”) plans equal to the plan’s funded status as of the measurement date. The primary assumptions are as follows: • Discount Rate—The discount rate is used in calculating the present value of benefits, which is based on projections of benefit payments to be made in the future. • Expected Return on Plan Assets—We project the future return on plan assets based on prior performance and future expectations for the types of investments held by the plans, as well as the expected long-term allocation of plan assets for these investments. These projected returns reduce the net benefit costs recorded currently. • Rate of Compensation Increase—For salary-related plans, we project employees’ annual pay increases, which are used to project employees’ pension benefits at retirement. • Mortality Assumptions—Assumptions about life expectancy of plan participants are used in the measurement of related plan obligations. Actuarial gains and losses are recognized annually in our consolidated statements of (loss) income in the fourth quarter and whenever a plan is determined to qualify for a remeasurement during a fiscal year. The remaining components of pension and OPEB plan expense, primarily service cost, interest cost and expected return on assets, are recorded on a monthly basis. The market-related value of assets equals the actual market value as of the date of measurement. During 2024, we made changes to assumptions related to discount rates and expected rates of return on plan assets. We consider available information that we deem relevant when selecting each of these assumptions. In selecting the discount rates for the U.S. plans, we consider expected benefit payments on a plan-by-plan basis. As a result, the Company uses different discount rates for each plan depending on the demographics of participants and the expected timing of benefit payments. For 2024, the discount rates were calculated using the results from a bond matching technique developed by Milliman, which matched the future estimated annual benefit payments of each respective plan against a portfolio of bonds of high quality to determine the discount rate. We believe our selected discount rates are determined using preferred methodology under authoritative accounting guidance and accurately reflect market conditions as of the December 31, 2024 measurement date. In selecting the discount rates for the foreign plans, we look at long-term yields on AA-rated corporate bonds when available. Our actuaries have developed yield curves based on the yields on the constituent bonds in the various indices as well as on other market indicators such as swap rates, particularly at the longer durations. For the Eurozone, we apply the Aon Hewitt yield curve to projected cash flows from the relevant plans to derive the discount rate. For the United Kingdom (“U.K.”), the discount rate is determined by applying the Aon Hewitt yield curve for typical schemes of similar duration to projected cash flows of Albemarle’s U.K. plan. In other countries where there is not a sufficiently deep market of high-quality corporate bonds, we set the discount rate by referencing the yield on government bonds of an appropriate duration. In estimating the expected return on plan assets, we consider past performance and future expectations for the types of investments held by the plan as well as the expected long-term allocation of plan assets to these investments. In projecting the rate of compensation increase, we consider past experience in light of movements in inflation rates. For the purpose of measuring our U.S. pension and OPEB obligations at December 31, 2024 and 2023, we used the Pri-2012 Mortality Tables along with the MP-2021 Mortality Improvement Scale, respectively, published by the SOA. Stock-based Compensation Expense The fair value of restricted stock awards, restricted stock unit awards and performance unit awards with a service condition are determined based on the number of shares or units granted and the quoted price of our common stock on the date of grant, and the fair value of stock options is determined using the Black-Scholes valuation model. The fair value of performance unit awards with a service condition and a market condition are estimated on the date of grant using a Monte Carlo simulation model. The fair value of these awards is determined after giving effect to estimated forfeitures. Such value is recognized as expense over the service period, which is generally the vesting period of the equity grant. To the extent restricted stock awards, restricted stock unit awards, performance unit awards and stock options are forfeited prior to vesting in excess of the estimated forfeiture rate, the corresponding previously recognized expense is reversed as an offset to operating expenses. Income Taxes We use the liability method for determining our income taxes, under which current and deferred tax liabilities and assets are recorded in accordance with enacted tax laws and rates. Under this method, the amounts of deferred tax liabilities and assets at the end of each period are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not. The Company’s deferred tax assets and liabilities are classified as noncurrent on the balance sheet, along with any related valuation allowance. Tax effects are released from Accumulated other comprehensive loss using either the specific identification approach or the portfolio approach based on the nature of the underlying item. Deferred income taxes are provided for the estimated income tax effect of temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. Deferred tax assets are also provided for operating losses, capital losses and certain tax credit carryovers. A valuation allowance, reducing deferred tax assets, is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The realization of such deferred tax assets is dependent upon the generation of sufficient future taxable income of the appropriate character. Although realization is not assured, we do not establish a valuation allowance when we believe it is more likely than not that a net deferred tax asset will be realized. The Company elected to not consider the estimated impact of potential future Corporate Alternative Minimum Tax liabilities for purposes of assessing valuation allowances on its deferred tax balances. We only recognize a tax benefit after concluding that it is more likely than not that the benefit will be sustained upon audit by the respective taxing authority based solely on the technical merits of the associated tax position. Once the recognition threshold is met, we recognize a tax benefit measured as the largest amount of the tax benefit that, in our judgment, is greater than 50% likely to be realized. Under current accounting guidance for uncertain tax positions, interest and penalties related to income tax liabilities are included in Income tax expense on the consolidated statements of (loss) income. We have designated the undistributed earnings of a portion of our f

Acquisitions

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions	Acquisitions: Guangxi Tianyuan New Energy Materials Acquisition On October 25, 2022, the Company completed the acquisition of all of the outstanding equity of Guangxi Tianyuan New Energy Materials Co., Ltd. (“Qinzhou”), for approximately $200 million in cash, which included the deferral of approximately $29 million. The full amount of the deferral, net of working capital adjustments, was paid in installments ending in July 2023. Qinzhou's operations include a lithium processing plant strategically positioned near the Port of Qinzhou in Guangxi, which began commercial production in the first half of 2022. The plant has designed annual conversion capacity of up to 25,000 metric tonnes of lithium carbonate equivalent (“LCE”) and is capable of producing battery-grade lithium carbonate and lithium hydroxide. The aggregate purchase price noted above was allocated to the major categories of assets and liabilities acquired based upon their estimated fair values at the acquisition closing date, which were based, in part, upon third-party appraisals for certain assets. The fair value of the assets and liabilities was primarily related to Property, plant and equipment of $106.6 million, Other intangibles of $16.3 million, net current liabilities of $5.5 million, and long-term liabilities of $7.1 million. The excess of the purchase price over the fair value of the net assets acquired was $76.8 million and was recorded as Goodwill within the Energy Storage reporting unit. The allocation of the purchase price was finalized in the third quarter of 2023. The fair value of the assets acquired and liabilities assumed was based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The discount rate is a significant assumption used in the valuation model. If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the consolidated financial statements could be subject to possible impairment. Goodwill arising from the acquisition was recorded within the Energy Storage segment and consists largely of anticipated synergies and economies of scale from the combined companies and overall strategic importance of the acquired businesses to Albemarle. The goodwill attributable to the acquisition is not amortizable or deductible for tax purposes. Acquisition, integration and potential divestiture related costs Acquisition, integration and potential divestiture related costs for the years ended December 31, 2024, 2023 and 2022 of $6.2 million, $26.8 million and $16.3 million were included in Selling, general and administrative expenses, respectively, on our consolidated statements of (loss) income. These include costs for the Qinzhou acquisitions noted above, as well as various other completed or potential acquisitions and divestitures.

The promissory note is payable in equal annual installments from the years 2027 to 2048. (b) During the first quarter of 2024, the Company issued 95,003 shares of common stock to certain employees in lieu of cash as payment of a portion of their 2023 annual incentive bonus plan. As part of the purchase price paid for the acquisition of a 60% interest in Wodgina in 2019, the Company transferred $17.3 million and $122.7 million of its construction in progress of the designated Kemerton assets during the years ended December 31, 2023 and 2022, respectively, representing MRL’s 40% interest in the assets at the time of transfer. Since the acquisition, the Company has transferred the full $480 million of construction in progress to MRL, as defined in the original purchase agreement. In addition, during the year ended December 31, 2022, the Company recorded expenses of $8.4 million related to cost overruns of the designated Kemerton assets. The cash outflow for these assets was recorded in Capital expenditures within Cash flows from investing activities on the consolidated statements of cash flows. The non-cash transfer of these assets is recorded in Other, net within Cash flows from operating activities on the consolidated statements of cash flows. Other, net within Cash flows from operating activities on the consolidated statements of cash flows for the years ended December 31, 2024, 2023 and 2022 included $82.7 million, $64.4 million and $41.8 million, respectively, representing the reclassification of the current portion of the one-time transition tax resulting from the enactment of the Tax Cuts and Jobs Act (“TCJA”) in 2017, from Other noncurrent liabilities to Income taxes payable within current liabilities. For additional information, see Note 20, “Income Taxes.” In addition, included in Other, net for the years ended December 31, 2024, 2023 and 2022 is $67.5 million, $39.9 million and ($21.8) million, respectively, related to gains (losses) on fluctuations in foreign currency exchange rates.

(b) As a result of the decline in lithium market pricing, the Company recorded charges in Cost of goods sold to reduce the value of certain finished goods and spodumene to their net realizable value. The balance of these inventory reserves totaled $104.0 million and $604.1 million at December 31, 2024 and 2023, respectively. Approximately 3% of our inventories are valued using the last-in, first-out (“LIFO”) method at both December 31, 2024 and 2023. The portion of our domestic inventories stated on the LIFO basis amounted to $44.5 million and $60.4 million at December 31, 2024 and 2023, respectively, which are below replacement cost by approximately $67.1 million and $60.1 million, respectively. The Company eliminates the balance of intra-entity profits on purchases of inventory from its equity method investments that remains unsold at the balance sheet in Inventories, specifically finished goods and equally reduces Equity in net income of unconsolidated investments (net of tax) on the consolidated statements of (loss) income. The balance of intra-entity profits on inventory purchased from equity method investments in Inventories totaled $66.8 million and $559.6 million at December 31, 2024 and 2023, 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 (loss) income.

Property, Plant and Equipment	Property, Plant and Equipment: Property, plant and equipment, at cost, consist of the following at December 31, 2024 and 2023 (in thousands): Useful December 31, 2024 2023 Land — $ 295,176 $ 297,435 Land improvements 10 – 30 342,213 316,544 Buildings and improvements 10 – 50 933,188 699,045 Machinery and equipment (a) 2 – 45 8,187,422 6,173,463 Mineral rights and reserves 7 – 60 1,755,770 1,689,013 Construction in progress — 1,009,599 3,058,257 Total $ 12,523,368 $ 12,233,757 (a) Consists primarily of (1) short-lived production equipment components, office and building equipment and other equipment with estimated lives ranging 2 – 7 years, (2) production process equipment (intermediate components) with estimated lives ranging 8 – 19 years, (3) production process equipment (major unit components) with estimated lives ranging 20 – 29 years, and (4) production process equipment (infrastructure and other) with estimated lives ranging 30 – 45 years. The cost of property, plant and equipment is depreciated generally by the straight-line method. Depletion of mineral rights is based on the units-of-production method. Depreciation expense, including depletion, amounted to $561.4 million, $398.5 million and $273.0 million during the years ended December 31, 2024, 2023 and 2022, respectively. Interest capitalized on significant capital projects in 2024, 2023 and 2022 was $49.0 million, $72.7 million and $31.1 million, respectively. In 2022, the Company announced it has been awarded a nearly $150 million grant from the U.S. Department of Energy to expand domestic manufacturing of batteries for EVs and the electric grid and for materials and components currently imported from other countries. The grant funding is intended to support a portion of the anticipated cost to construct a new, commercial-scale U.S.-based lithium concentrator facility at our Kings Mountain, North Carolina location. The grant will be received over the life of the construction period for the new facility (projected through 2028) as reimbursement for capital expenditures. To further support the restart of the Kings Mountain mine, in 2023, we announced a $90 million critical materials award from the U.S. Department of Defense. As funds are received for both of these grants, the Company will reduce the cost of the assets by the amount of the grant, and income will be recognized by the lower depreciation expense over the useful life of the assets. During the year ended December 31, 2024, the Company received $12.4 million of these funds, which reduced the cost of Property, plant and equipment on the balance sheet.

Undistributed earnings attributable to our significant unconsolidated investments represented approximately $464.6 million and $97.3 million of our consolidated retained earnings at December 31, 2024 and 2023, respectively. All of the unconsolidated joint ventures in which we have investments are private companies and, accordingly, do not have a quoted market price available. The following summary lists the assets, liabilities and results of operations for the Company’s significant unconsolidated joint ventures presented herein (in thousands): December 31, 2024 2023 Summary of Balance Sheet Information: Current assets $ 968,453 $ 1,424,059 Noncurrent assets 2,707,216 2,321,261 Total assets $ 3,675,669 $ 3,745,320 Current liabilities $ 390,522 $ 773,931 Noncurrent liabilities 1,727,181 1,267,271 Total liabilities $ 2,117,703 $ 2,041,202 Year Ended December 31, 2024 2023 2022 Summary of Statements of Income Information: Net sales $ 1,810,801 $ 7,019,117 $ 4,290,223 Gross profit $ 1,047,714 $ 6,373,472 $ 3,765,304 Income before income taxes $ 695,932 $ 5,988,737 $ 3,301,875 Net income $ 485,392 $ 4,224,961 $ 2,314,094 We have evaluated each of the unconsolidated investments pursuant to current accounting guidance and none qualify for consolidation. Dividends received from our significant unconsolidated investments were $346.8 million, $2.0 billion and $800.9 million in 2024, 2023 and 2022, respectively. The Company holds a 49% equity interest in Windfield, which we acquired in the Rockwood acquisition. With regards to the Company’s ownership in Windfield, the 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, the Company does not consolidate Windfield as it is not the primary beneficiary. The carrying amount of our 49% equity interest in Windfield, which is within the Energy Storage segment and the most significant VIE, was $583.6 million and $712.0 million at December 31, 2024 and 2023, respectively. The Company’s unconsolidated VIEs are reported in Investments in 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. Proportionately Consolidated Joint Ventures On October 18, 2023, the Company closed on the restructuring of the MARBL joint venture with MRL. This updated structure is intended to significantly simplify the commercial operation agreements previously entered into, allowed us to retain full control of downstream conversion assets and provide greater strategic opportunities for each company based on their global operations and the evolving lithium market. Under the amended agreements, Albemarle acquired the remaining 40% ownership of the Kemerton lithium hydroxide processing facility in Australia that was jointly owned with MRL through the MARBL joint venture, bringing Albemarle’s ownership in the processing facility to 100%. Following this restructuring, Albemarle and MRL each own 50% of Wodgina, and MRL operates the Wodgina mine on behalf of the joint venture. During the fourth quarter of 2023, Albemarle paid MRL approximately $380 million in cash, which included $180 million of consideration for the remaining ownership of Kemerton as well as a payment for the economic effective date of the transaction being retroactive to April 1, 2022. As a result of this transaction, the Company recorded a gain of $71.2 million on the consolidated statement of (loss) income during the fourth quarter of 2023. The fair value of the 40% ownership of the Kemerton lithium hydroxide processing facility was based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the consolidated financial statements could be subject to possible impairment. This joint venture is unincorporated with each investor holding an undivided interest in each asset and proportionately liable for each liability; therefore, our proportionate share of assets, liabilities, revenue and expenses are included in the appropriate classifications in the consolidated financial statements. Public Equity Securities Included in the Company’s marketable equity securities balance are holdings in equity securities of public companies. The fair value is measured using publicly available share prices of the investments, with any changes reported in Other income, net in our consolidated statements of (loss) income. During the year ended December 31, 2023, the Company purchased approximately $203.4 million of shares in publicly-traded companies. In addition, during the years ended December 31, 2024, 2023 and 2022, the Company recorded unrealized mark-to-market (losses) gains of ($37.0) million, ($41.4) million and $4.3 million, respectively, in Other income, net for all public equity securities held at the end of the balance sheet date. In January 2024, the Company sold equity securities of a public company for proceeds of approximately $81.5 million. As a result of the sale, the Company realized a loss of $33.7 million in the year ended December 31, 2024. Other The Company holds a 50% equity interest in Jordan Bromine Company Limited (“JBC”), reported in the Specialties segment. The Company consolidates this venture as it is considered the primary beneficiary due to its operational and financial control. As part of the proceeds from the sale of the fine chemistry services (“FCS”) business on June 1, 2021, W.R. Grace & Co. (“Grace”) issued Albemarle preferred equity of a Grace subsidiary having an aggregate stated value of $270 million. The preferred equity can be redeemed at Grace’s option under certain conditions and began accruing payment-in-kind (“PIK”) dividends at an annual rate of 12% on June 1, 2023. In addition, the preferred equity can be redeemed by Albemarle when the accumulated balance reaches 200% of the original value. This preferred equity had a fair value of $314.0 million and $289.3 million at December 31, 2024 and 2023, respectively, which is reported in Investments in the consolidated balance sheets. We maintain a Benefit Protection Trust (the “Trust”) that was created to provide a source of funds to assist in meeting the obligations of our Executive Deferred Compensation Plan (“EDCP”), subject to the claims of our creditors in the event of our insolvency. Assets of the Trust, in conjunction with our EDCP, are accounted for as trading securities in accordance with authoritative accounting guidance. The assets of the Trust consist primarily of mutual fund investments and are marked-to-market on a monthly basis through the consolidated statements of (loss) income. At December 31, 2024 and 2023, these marketable securities amounted to $38.2 million and $33.6 million, respectively.

The effective interest rate on these senior notes is approximately 4.84%. These senior notes mature on June 1, 2027. • $600.0 million aggregate principal amount of senior notes, bearing interest at a rate of 5.05% payable semi-annually on June 1 and December 1 of each year, beginning on December 1, 2022. The effective interest rate on these senior notes is approximately 5.18%. These senior notes mature on June 1, 2032. • $450.0 million aggregate principal amount of senior notes, bearing interest at a rate of 5.65% payable semi-annually on June 1 and December 1 of each year, beginning on December 1, 2022. The effective interest rate on these senior notes is approximately 5.71%. These senior notes mature on June 1, 2052. The net proceeds from the issuance of the 2022 Notes were used to repay the balance of the commercial paper notes, the remaining balance of $425.0 million of the 4.15% Senior Notes due 2024 (the “2024 Notes”) and for general corporate purposes. The 2024 Notes were originally due to mature on December 15, 2024 and bore interest at a rate of 4.15%. During the year ended December 31, 2022, the Company recorded a loss on early extinguishment of debt of $19.2 million in Interest and financing expenses, representing the tender premiums, fees, unamortized discounts and unamortized deferred financing costs from the redemption of the 2024 Notes. In addition, the loss on early extinguishment of debt includes the accelerated amortization of the interest rate swap associated with the 2024 Notes from Accumulated other comprehensive loss. 2019 Notes The Company has the following outstanding series of notes originally issued on November 25, 2019 (collectively, the “2019 Notes”) as follows: • €377.1 million aggregate principal amount of notes, bearing interest at a rate of 1.125% payable annually on November 25 of each year, beginning in 2020. The effective interest rate on these notes is approximately 1.30%. These notes mature on November 25, 2025. • €500.0 million aggregate principal amount of notes, bearing interest at a rate of 1.625% payable annually on November 25 of each year, beginning in 2020. The effective interest rate on these notes is approximately 1.74%. These notes mature on November 25, 2028. • $171.6 million aggregate principal amount of senior notes, bearing interest at a rate of 3.45% payable semi-annually on May 15 and November 15 of each year, beginning in 2020. The effective interest rate on these senior notes is approximately 3.58%. These senior notes mature on November 15, 2029. 2014 Senior Notes We currently have outstanding $350.0 million aggregate principal amount of senior notes issued on November 24, 2014, bearing interest at a rate of 5.45% payable semi-annually on June 1 and December 1 of each year, beginning June 1, 2015. The effective interest rate on these senior notes is approximately 5.50%. These senior notes mature on December 1, 2044. On January 22, 2014, we entered into a pay fixed, receive variable rate forward starting interest rate swap, with a notional amount of $325.0 million, with J.P. Morgan Chase Bank, N.A., to be effective October 15, 2014. Our risk management objective and strategy for undertaking this hedge was to eliminate the variability in the interest rate and partial credit spread on the 20 future semi-annual coupon payments that were to be paid in connection with the 2024 Notes. On October 15, 2014, the swap was settled, resulting in a payment to the counterparty of $33.4 million. This amount was recorded in Accumulated other comprehensive loss and was to be amortized to interest expense over the life of the 2024 Notes. As noted above, the 2024 Notes were repaid in the second quarter of 2022, and as a result, the unamortized balance of this interest rate swap was reclassified to interest expense during the same period as part of the early extinguishment of debt. Credit Agreements Given economic conditions, specifically around the market pricing of lithium, and the related anticipated impact on the Company’s future earnings, on October 31, 2024 the Company further amended its revolving, unsecured amended and restated credit agreement dated October 28, 2022, as previously amended on February 9, 2024 (the “2022 Credit Agreement”), which provides for borrowings of up to $1.5 billion and matures on October 28, 2027. Borrowings under the 2022 Credit Agreement bear interest at variable rates based on a benchmark rate depending on the currency in which the loans are denominated, plus an applicable margin which ranges from 0.910% to 1.375%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services LLC (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”). With respect to loans denominated in U.S. dollars, interest is calculated using the term Secured Overnight Financing Rate (“SOFR”) plus a term SOFR adjustment of 0.10%, plus the applicable margin. The applicable margin on the facility was 1.20% as of December 31, 2024. There were no borrowings outstanding under the 2022 Credit Agreement as of December 31, 2024. Borrowings under the 2022 Credit Agreement are conditioned upon satisfaction of certain customary conditions precedent, including the absence of defaults. The October 2024 amendment was entered into to modify the financial covenants under the 2022 Credit Agreement to avoid a potential covenant violation through June 2026 given the market pricing of lithium. The amended 2022 Credit Agreement subjects the Company to two financial covenants, as well as customary affirmative and negative covenants. The amended first financial covenant requires that the ratio of (a) (i) the Company’s consolidated net funded debt plus a proportionate amount of Windfield’s net funded debt less (ii) the Company’s unrestricted cash and cash equivalents plus a proportionate amount of Windfield’s unrestricted cash and cash equivalents (up to a specified amount) to (b) consolidated Windfield-Adjusted EBITDA (as such terms are defined in the 2022 Credit Agreement) be less than or equal to: (i) 4.00:1.0 as of the end of the fourth quarter of 2024, (ii) 4.75:1.0 as of the end of the first quarter of 2025, (iii) 5.75:1.0 as of the end of the second quarter of 2025, (iv) 5.50:1.0 as of the end of the third quarter of 2025, (v) 5.00:1.0 as of the end of the fourth quarter of 2025 (vi) 4.75:1.0 as of the end of the first and the second quarters of 2026, respectively and (vii) 3.50:1.0 as of the end of the third quarter of 2026 and each fiscal quarter thereafter through the third quarter of 2027. The maximum permitted leverage ratios described above are subject to adjustment in accordance with the terms of the 2022 Credit Agreement upon the consummation of an acquisition after June 30, 2026 if the consideration includes cash proceeds from issuance of funded debt in excess of $500 million. The amended second financial covenant requires that, beginning as of the end of the fourth quarter of 2024, the ratio of the Company’s consolidated EBITDA to consolidated interest charges (as such terms are defined in the 2022 Credit Agreement) be no less than (i) 1.00:1.0 as of the end of each fiscal quarter through the second quarter of 2025, (ii) 2.00:1.0 as of the end of the third quarter of 2025, (iii) 2.50:1.0 as of the end of the fourth quarter of 2025, and (iv) 3.00:1.0 as of the end of each fiscal quarter thereafter. The 2022 Credit Agreement also contains customary default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants and cross-defaults to other material indebtedness. The occurrence of an event of default under the 2022 Credit Agreement could result in all loans and other obligations becoming immediately due and payable and the commitments under the 2022 Credit Agreement being terminated. Following the $2.2 billion issuance of mandatory convertible preferred stock in March 2024 and the amendments to the financial covenants, the Company expects to maintain compliance with the amended financial covenants for the next twelve months. In addition to the amended covenants, the Company has introduced additional cost reduction plans to further reduce operating expenses and capital investments, as discussed in Note 17, “Restructuring Charges and Asset Write-offs.” No assurances can be given that any additional cost reduction strategies undertaken will be sufficient to meet the amended financial covenants. Further, a significant and extended downturn in lithium market prices or demand could impact the Company’s ability to maintain compliance with its amended financial covenants and it could require the Company to seek additional amendments to the 2022 Credit Agreement and/or issue debt or equity securities to fund its activities and maintain financial flexibility. If the Company were unable to obtain such necessary additional amendments, this could lead to an event of default and its lenders could require the Company to repay its outstanding debt. In that situation, the Company may not be able to raise sufficient debt or equity capital, or divest assets, to refinance or repay the lenders. Commercial Paper Notes On May 29, 2013, we entered into agreements to initiate a commercial paper program on a private placement basis under which we may issue unsecured commercial paper notes (the “Commercial Paper Notes”) from time-to-time. On May 17, 2023, we entered into definitive documentation to increase the size of our existing commercial paper program. The maximum aggregate face amount of Commercial Paper Notes outstanding at any time is $1.5 billion. The proceeds from the issuance of the Commercial Paper Notes are expected to be used for general corporate purposes, including the repayment of other debt of the Company. The 2022 Credit Agreement is available to repay the Commercial Paper Notes, if necessary. Aggregate borrowings outstanding under the 2022 Credit Agreement and the Commercial Paper Notes will not exceed the $1.5 billion current maximum amount available under the 2022 Credit Agreement. The Commercial Paper Notes will be sold at a discount from par, or alternatively, will be sold at par and bear interest at rates that will vary based upon market conditions at the time of issuance. The maturities of the Commercial Paper Notes will vary but may not exceed 397 days. During the year ended December 31, 2024, we repaid a net amount of $620.0 million of commercial paper notes using the net proceeds received from the issuance of mandatory convertible preferred stock. See Note 16, “Equity,” for additional information. Other In the second quarter of 2023, the Company received a loan of $300.0 million to be repaid in five equal annual installments beginning on December 31, 2026. This interest-free loan was discounted using an imputed interest rate of 5.53% and the Company will amortize that discount through Interest and financing expenses over the term of the loan. We have additional uncommitted credit lines with various U.S. and foreign financial institutions that provide for borrowings of up to approximately $182.2 million at December 31, 2024. Outstanding borrowings under these agreements were $27.5 million and $30.2 million at December 31, 2024 and 2023, respectively. The average interest rate on borrowings under these agreements during 2024, 2023 and 2022 was approximately 0.3%. At December 31, 2024 and 2023, we had the ability and intent to refinance our borrowings under our other existing credit lines with borrowings under the 2022 Credit Agreement. Therefore, the amounts outstanding under those credit lines, if any, are classified as long-term debt at December 31, 2024 and 2023. At December 31, 2024, we had the ability to borrow a total of $1.5 billion under our commercial paper program and the Credit Agreements. We believe that as of December 31, 2024, we were, and currently are, in compliance with all of our debt covenants.

Retirement Benefits [Abstract]
Pension Plans and Other Postretirement Benefits	Pension Plans and Other Postretirement Benefits: We maintain various noncontributory defined benefit pension plans covering certain employees, primarily in the U.S., the U.K., Germany and Japan. We also have a contributory defined benefit plan covering certain Belgian employees. The benefits for these plans are based primarily on compensation and/or years of service. Our U.S. and U.K. defined benefit plans for non-represented employees are closed to new participants, with no additional benefits accruing under these plans as participants’ accrued benefits have been frozen. The funding policy for each plan complies with the requirements of relevant governmental laws and regulations. The pension information for all periods presented includes amounts related to salaried and hourly plans. The following provides a reconciliation of benefit obligations, plan assets and funded status, as well as a summary of significant assumptions, for our defined benefit pension plans (in thousands): Year Ended December 31, 2024 Year Ended December 31, 2023 U.S. Pension Plans Foreign Pension Plans U.S. Pension Plans Foreign Pension Plans Change in benefit obligations: Benefit obligation at January 1 $ 512,902 $ 195,918 $ 514,971 $ 180,561 Service cost 545 5,391 499 5,686 Interest cost 25,580 7,204 26,924 7,153 Actuarial (gain) loss (11,604) (7,034) 11,957 10,078 Benefits paid (42,355) (9,423) (41,449) (9,051) Employee contributions — 70 — 60 Foreign exchange (gain) loss — (7,920) — 7,137 Settlements/curtailments — (6,197) — (5,606) Other — (56) — (100) Benefit obligation at December 31 $ 485,068 $ 177,953 $ 512,902 $ 195,918 Change in plan assets: Fair value of plan assets at January 1 $ 484,131 $ 65,514 $ 469,828 $ 58,229 Actual return on plan assets 33,707 (1,317) 54,785 4,395 Employer contributions 1,911 15,498 967 14,496 Benefits paid (42,355) (9,423) (41,449) (9,051) Employee contributions — 70 — 60 Foreign exchange (loss) gain — (1,771) — 3,091 Settlements/curtailments — (6,197) — (5,606) Other — (56) — (100) Fair value of plan assets at December 31 $ 477,394 $ 62,318 $ 484,131 $ 65,514 Funded status at December 31 $ (7,674) $ (115,635) $ (28,771) $ (130,404) December 31, 2024 December 31, 2023 U.S. Pension Plans Foreign Pension Plans U.S. Pension Plans Foreign Pension Plans Amounts recognized in consolidated balance sheets: Current liabilities (accrued expenses) $ (928) $ (6,189) $ (912) $ (7,951) Noncurrent liabilities (pension benefits) (6,746) (109,446) (27,859) (122,453) Net pension liability $ (7,674) $ (115,635) $ (28,771) $ (130,404) Amounts recognized in accumulated other comprehensive loss: Prior service benefit $ — $ (441) $ — $ (531) Net amount recognized $ — $ (441) $ — $ (531) Weighted-average assumptions used to determine benefit obligations at December 31: Discount rate 5.65 % 4.04 % 5.21 % 3.73 % Rate of compensation increase — % 3.65 % — % 3.67 % The accumulated benefit obligation for all defined benefit pension plans was $655.9 million and $700.4 million at December 31, 2024 and 2023, respectively. Postretirement medical benefits and life insurance is provided for certain groups of U.S. retired employees. Medical and life insurance benefit costs have been funded principally on a pay-as-you-go basis. Although the availability of medical coverage after retirement varies for different groups of employees, the majority of employees who retire before becoming eligible for Medicare can continue group coverage by paying a portion of the cost of a monthly premium designed to cover the claims incurred by retired employees subject to a cap on payments allowed. The availability of group coverage for Medicare-eligible retirees also varies by employee group with coverage designed either to supplement or coordinate with Medicare. Retirees generally pay a portion of the cost of the coverage. Plan assets for retiree life insurance are held under an insurance contract and are reserved for retiree life insurance benefits. In 2005, the postretirement medical benefit available to U.S. employees was changed to provide that employees who are under age 50 as of December 31, 2005 would no longer be eligible for a company-paid retiree medical premium subsidy. Employees who are of age 50 and above as of December 31, 2005 and who retire after January 1, 2006 will have their retiree medical premium subsidy capped. Effective January 1, 2008, our medical insurance for certain groups of U.S. retired employees is now insured through a medical carrier.

The mark-to-market actuarial gain in 2024 was primarily attributable to an increase in the weighted-average discount rate to 5.65% from 5.21% for our U.S. pension plans and to 4.04% from 3.73% for our foreign pension plans to reflect market conditions as of the December 31, 2024 measurement date. This was partially offset by a lower return on pension plan assets during the year than was expected, as a result of overall market and investment portfolio performance. The weighted-average actual return on our U.S. and foreign pension plan assets was 5.89% versus an expected return of 6.77%. The mark-to-market actuarial gain in 2023 was primarily attributable to a higher return on pension plan assets during the year than was expected, as a result of overall market and investment portfolio performance. The weighted-average actual return on our U.S. and foreign pension plan assets was 11.21% versus an expected return of 6.66%. This was partially offset by a decrease in the weighted-average discount rate to 5.21% from 5.46% for our U.S. pension plans and to 3.73% from 4.04% for our foreign pension plans to reflect market conditions as of the December 31, 2023 measurement date. The mark-to-market actuarial gain in 2022 was primarily attributable to a significant increase in the weighted-average discount rate to 5.46% from 2.86% for our U.S. pension plans and to 4.04% from 1.44% for our foreign pension plans to reflect market conditions as of the December 31, 2022 measurement date. This was partially offset by a lower return on pension plan assets in 2022 than was expected, as a result of overall market and investment portfolio performance. The weighted-average actual return on our U.S. and foreign pension plan assets was (17.94)% versus an expected return of 6.48%. 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 1 Unadjusted quoted prices in active markets for identical assets or liabilities Level 2 Unadjusted 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 3 Unobservable 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. Investments for which market quotations are readily available are valued at the closing price on the last business day of the year. Listed securities for which no sale was reported on such date are valued at the mean between the last reported bid and asked price. Securities traded in the over-the-counter market are valued at the closing price on the last business day of the year or at bid price. The net asset value of shares or units is based on the quoted market value of the underlying assets. The market value of corporate bonds is based on institutional trading lots and is most often reflective of bid price. Government securities are valued at the mean between bid and ask prices. Holdings in private equity securities are typically valued using the net asset valuations provided by the underlying private investment companies. The following tables set forth the assets of our pension and postretirement plans that were accounted for at fair value on a recurring basis as of December 31, 2024 and 2023 (in thousands): December 31, 2024 Quoted Prices in Active Markets for Identical Items (Level 1) Quoted Prices in Active Markets for Similar Items (Level 2) Unobservable Inputs (Level 3) Pension Assets: Domestic Equity (a) $ 78,124 $ 78,124 $ — $ — International Equity (b) 78,124 69,471 8,653 — Fixed Income (c) 318,036 286,549 31,487 — Absolute Return Measured at Net Asset Value (d) 56,888 — — — Cash 8,540 8,540 — — Total Pension Assets $ 539,712 $ 442,684 $ 40,140 $ — December 31, 2023 Quoted Prices in Active Markets for Identical Items (Level 1) Quoted Prices in Active Markets for Similar Items (Level 2) Unobservable Inputs (Level 3) Pension Assets: Domestic Equity (a) $ 58,906 $ 58,906 $ — $ — International Equity (b) 106,491 99,432 7,059 — Fixed Income (c) 294,140 257,299 36,841 — Absolute Return Measured at Net Asset Value (d) 80,542 — — — Cash 9,566 9,566 — — Total Pension Assets $ 549,645 $ 425,203 $ 43,900 $ — (a) Consists primarily of U.S. stock funds that track or are actively managed and measured against the S&P 500 index. (b) Consists primarily of international equity funds that invest in common stocks and other securities whose value is based on an international equity index or an underlying equity security or basket of equity securities. (c) Consists primarily of debt obligations issued by governments, corporations, municipalities and other borrowers. Also includes insurance policies. (d) Consists primarily of funds with holdings in private investment companies. See additional information about the Absolute Return investments below. Holdings in private investment companies are measured at fair value using the net asset value per share as a practical expedient and have not been categorized in the fair value hierarchy. Their fair values are included in this table to permit reconciliation to the reconciliation of plan assets table above. The Company’s pension plan assets in the U.S. and U.K. represent approximately 96% of the total pension plan assets. The investment objective of these pension plan assets is to achieve solid returns while preserving capital to meet current plan cash flow requirements. Assets should participate in rising markets, with defensive action in declining markets expected to an even greater degree. Depending on market conditions, the broad asset class targets may range up or down by approximately 10%. These asset classes include but are not limited to hedge fund of funds, bonds and other fixed income vehicles, high yield fixed income securities, equities and distressed debt. At December 31, 2024 and 2023, equity securities held by our pension and OPEB plans did not include direct ownership of Albemarle common stock. The weighted-average target allocations as of the measurement date are as follows: Target Allocation Equity securities 35 % Fixed income 59 % Absolute return 6 % Our Absolute Return investments consist primarily of our investments in hedge fund of funds. These are holdings in private investment companies with fair values that are based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers or fund managers associated with these investments provide valuations of the investments on a monthly basis utilizing the net asset valuation approach for determining fair values. These valuations are reviewed by the Company for reasonableness based on applicable sector, benchmark and company performance to validate the appropriateness of the net asset values as a fair value measurement. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation. In general, the investment objective of these funds is high risk-adjusted returns with an emphasis on preservation of capital. The investment strategies of each of the funds vary; however, the objective of our Absolute Return investments is complementary to the overall investment objective of our U.S. pension plan assets. We made contributions to our defined benefit pension and OPEB plans of $19.4 million, $17.9 million and $16.1 million during the years ended December 31, 2024, 2023 and 2022, respectively. We expect contributions to our domestic nonqualified and foreign qualified and nonqualified pension plans to approximate $16.5 million in 2025. Also, we expect to pay approximately $2.5 million in premiums to our U.S. postretirement benefit plan in 2025. However, we may choose to make additional voluntary pension contributions in excess of these amounts. The current forecast of benefit payments, which reflects expected future service, amounts to (in thousands): U.S. Pension Plans Foreign Pension Plans Other Postretirement Benefits 2025 $ 44,303 $ 11,655 $ 2,548 2026 $ 44,088 $ 10,983 $ 2,770 2027 $ 43,703 $ 11,760 $ 2,830 2028 $ 43,099 $ 11,928 $ 2,875 2029 $ 42,079 $ 13,427 $ 2,902 2030-2034 $ 193,724 $ 58,399 $ 14,284 We have a supplemental executive retirement plan (“SERP”), which provides unfunded supplemental retirement benefits to certain management or highly compensated employees. The SERP provides for incremental pension benefits to offset the limitations imposed on qualified plan benefits by federal income tax regulations. Costs (credits) relating to our SERP were $0.7 million, $0.6 million and ($1.2) million for the years ended December 31, 2024, 2023 and 2022, respectively. The projected benefit obligation for the SERP recognized in the consolidated balance sheets at December 31, 2024 and 2023 was $5.9 million and $6.2 million, respectively. The benefit expenses and obligations of this SERP are included in the tables above. Benefits of $0.9 million are expected to be paid to SERP retirees in 2025. On October 1, 2012, our Board of Directors approved amendments to the SERP, such that effective December 31, 2014, no additional benefits shall accrue under this plan and participants’ accrued benefits shall be frozen as of that date to reflect the same changes as were made under the U.S. qualified defined benefit plan. At December 31, 2024, the assumed rate of increase in the pre-65 and post-65 per capita cost of covered health care benefits for U.S. retirees was zero as the employer-paid premium caps (pre-65 and post-65) were met starting January 1, 2013. Defined Contribution Plans On March 31, 2004, a new defined contribution pension plan benefit was adopted under the qualified defined contribution plan for U.S. non-represented employees hired after March 31, 2004. On October 1, 2012, our Board of Directors approved certain plan amendments, such that effective January 1, 2013, the defined contribution pension plan benefit is expanded to include non-represented employees hired prior to March 31, 2004, and revised the contribution for all participants to be based on 5% of eligible employee compensation. The employer portion of contributions to our U.S. defined contribution pension plan amounted to $18.3 million, $17.8 million, and $12.1 million in 2024, 2023 and 2022, respectively. Certain of our employees participate in our defined contribution 401(k) employee savings plan, which is generally available to all U.S. full-time salaried and non-union hourly employees and to employees who are covered by a collective bargaining agreement that provides for such participation. This U.S. defined contribution plan is funded with contributions made by the participants and us. Our contributions to the 401(k) plan amounted to $20.4 million, $18.4 million and $12.7 million in 2024, 2023 and 2022, respectively.

Under these agreements, we transfer the related assets to various local government entities and receive bonds. We immediately lease the facilities from the local government entities and have an option to repurchase the facilities for a nominal amount upon tendering the bonds to the local government entities at various predetermined dates. The bonds and the associated obligations for the leases of the facilities offset values, and the underlying assets are recorded in property, plant and equipment.

Commitments and Contingencies	Commitments and Contingencies: In the ordinary course of business, we have commitments in connection with various activities. We believe that amounts recorded are adequate for known items which might become due in the current year. The most significant commitments are as follows: Environmental We had the following activity in our recorded environmental liabilities for the years ended December 31, 2024, 2023 and 2022 (in thousands): Year Ended December 31, 2024 2023 2022 Balance, beginning of year $ 34,149 $ 38,245 $ 46,617 Expenditures (4,159) (3,393) (10,378) Accretion of discount 1,126 1,094 1,031 Additions, liability releases and changes in estimates, net (11,304) (2,541) 673 Foreign currency translation adjustments and other 211 744 302 Balance, end of year 20,023 34,149 38,245 Less amounts reported in Accrued expenses 4,240 10,925 6,973 Amounts reported in Other noncurrent liabilities $ 15,783 $ 23,224 $ 31,272 Environmental remediation liabilities included discounted liabilities of $16.8 million and $27.4 million at December 31, 2024 and 2023, respectively, discounted at rates with a weighted-average of 4.0% and 3.7%, respectively, with the undiscounted amount totaling $34.5 million and $55.4 million at December 31, 2024 and 2023, respectively. For certain locations where the Company is operating groundwater monitoring and/or remediation systems, prior owners or insurers have assumed all or most of the responsibility. 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 the 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 $42 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. Asset Retirement Obligations The following is a reconciliation of our beginning and ending asset retirement obligation balances for 2024 and 2023 (in thousands): Year Ended December 31, 2024 2023 Balance, beginning of year $ 89,159 $ 80,101 Additions and changes in estimates 6,608 11,288 Accretion of discount 3,365 2,421 Liabilities settled (2,653) (3,044) Foreign currency translation adjustments and other (90) (1,607) Balance, end of year $ 96,389 $ 89,159 Less amounts reported in Accrued expenses 1,535 456 Amounts reported in Other noncurrent liabilities $ 94,854 $ 88,703 Asset retirement obligations primarily relate to post-closure reclamation of brine wells and sites involved in the surface mining and manufacturing of lithium. We are not aware of any conditional asset retirement obligations that would require recognition in our consolidated financial statements. 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. As first reported in 2018, following receipt of information regarding potential improper payments being made by third-party sales representatives of our Refining Solutions business, within what is now the Ketjen segment, we investigated and voluntarily self-reported potential violations of the U.S. Foreign Corrupt Practices Act to the U.S. Department of Justice (“DOJ”) and the SEC, and also reported this conduct to the Dutch Public Prosecutor (“DPP”). We cooperated with these agencies in their investigations of this historical conduct and implemented appropriate remedial measures intended to strengthen our compliance program and related internal controls. In September 2023, the Company finalized agreements to resolve these matters with the DOJ and SEC. The DPP has confirmed it will not pursue action in this matter. In connection with this resolution, which relates to conduct prior to 2018, we entered into a non-prosecution agreement with the DOJ and an administrative resolution with the SEC, pursuant to which we paid a total of $218.5 million in aggregate fines, disgorgement, and prejudgment interest to the DOJ and SEC. The resolution does not include a compliance monitorship, although the Company has agreed to certain ongoing compliance reporting obligations. During the year ended December 31, 2023, the Company recorded a charge of $218.5 million in Selling, General and Administrative Expenses in its consolidated statement of operations and accrued a corresponding liability on its consolidated balance sheet for these agreements. The agreed upon amounts were paid to the DOJ and SEC in October 2023, with this matter considered finalized and no future financial obligations expected. 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 who 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 who 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 $12.6 million and $14.5 million at December 31, 2024 and 2023, 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 2017. Other The Company has standby letters of credit and guarantees with various financial institutions. The following table summarizes our letters of credit and guarantee agreements (in thousands): 2025 2026 2027 2028 2029 Thereafter Letters of credit and other guarantees $ 101,662 $ 5,369 $ 2,667 $ 656 $ — $ 5,310 The outstanding letters of credit are primarily related to insurance claim payment guarantees. The majority of the Company’s other guarantees have terms of one year and mainly consist of performance and environmental guarantees, as well as guarantees to customs and port authorities. The guarantees arose during the ordinary course of business. We do not have recorded reserves for the letters of credit and guarantees as of December 31, 2024. We are unable to estimate the maximum amount of the potential future liability under guarantees and letters of credit. However, we accrue for any potential loss for which we believe a future payment is probable and a range of loss can be reasonably estimated. We believe our liability under such obligations is immaterial. We currently, and are from time to time, subject to transactional audits in various taxing jurisdictions and to customs audits globally. We do not expect the financial impact of any of these audits to have a material adverse effect on the Company’s results of operations, financial condition or cash flows.

Equity [Abstract]
Equity	Equity: Common Stock On May 9, 2024, the Company filed to amend the Company’s Amended and Restated Articles of Incorporation (the “Charter”) to increase the number of authorized shares of common stock, $0.01 par value per share, from 150,000,000 to 275,000,000 (the “Charter Amendment”). The Charter Amendment became effective May 10, 2024. Mandatory Convertible Preferred Stock On March 8, 2024, the Company issued 46,000,000 depositary shares (“Depositary Shares”), each representing a 1/20th interest in a share of Series A Mandatory Convertible Preferred Stock (“Mandatory Convertible Preferred Stock”). The 2,300,000 shares of Mandatory Convertible Preferred Stock issued has a $1,000 per share liquidation preference. As a result of this transaction, the Company received cash proceeds of approximately $2.2 billion, net of underwriting fees and offering costs. The Company intends to use the proceeds for general corporate purposes, which may include, among other uses, funding capital expenditures, following the repayment of commercial paper with a portion of the proceeds in the first quarter of 2024. Dividends on the Mandatory Convertible Preferred Stock are payable on a cumulative basis when, as and if declared by the Albemarle board of directors, or an authorized committee thereof, at an annual rate of 7.25% on the liquidation preference of $1,000 per share, and may be paid in cash or, subject to certain limitations, in shares of common stock or, subject to certain limitations, any combination of cash and shares of common stock. Dividends that are declared on the Mandatory Convertible Preferred Stock will be payable quarterly to the holders of record on February 15, May 15, August 15 and November 15 of each year, immediately preceding the relevant dividend payment date, whether or not such holders convert their Depositary Shares, or such Depositary Shares are automatically converted, after a record date and on or prior to the immediately succeeding dividend payment date. Dividends of $17.12 per share of Mandatory Convertible Preferred Stock were paid in June 2024 and dividends of $18.125 per share of Mandatory Convertible Preferred Stock were paid in September and December 2024. Subsequent quarterly cash dividends are expected to be $18.125 per share of Mandatory Convertible Preferred Stock. Dividends are expected to be paid on March 1, June 1, September 1 and December 1 of each year ending on, and including, March 1, 2027. The Company may not redeem the shares of the Mandatory Convertible Preferred Stock. However, at its option, the Company may purchase the Mandatory Convertible Preferred Stock from time to time on the open market, by tender offer, exchange offer or otherwise. Unless converted earlier in accordance with its terms, each share of Mandatory Convertible Preferred Stock will automatically convert on the mandatory conversion date, which is expected to be March 1, 2027, into between 7.618 shares and 9.140 shares of common stock, in each case, subject to customary anti-dilution adjustments described in the certificate of designations related to the Mandatory Convertible Preferred Stock (the “Certificate of Designations”). The number of shares of common stock issuable upon conversion will be determined based on the average volume weighted average price per share of common stock over the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately prior to March 1, 2027. Holders of shares of Mandatory Convertible Preferred Stock have the option to convert all or any portion of their shares of the Mandatory Convertible Preferred Stock at any time. The conversion rate applicable to any early conversion may in certain circumstances be increased to compensate holders of the Mandatory Convertible Preferred Stock for certain unpaid accumulated dividends in the Certificate of Designations. If a Fundamental Change, as defined in the Certificate of Designations, occurs on or prior to March 1, 2027, then holders of the Mandatory Convertible Preferred Stock will be entitled to convert all or any portion of their Mandatory Convertible Preferred Stock at the fundamental change conversion rate, as defined in the Certificate of Designations, as for a specified period of time and to also receive an amount to compensate them for certain unpaid accumulated dividends and any remaining future scheduled dividend payments. There were 2,300,000 shares of Mandatory Convertible Preferred Stock issued and outstanding at December 31, 2024.

During the year ended December 31, 2024, the Company dedesignated the remaining foreign currency forward contracts accounted for as cash flow hedges. The related loss was reclassified to Other income, net during the year ended December 31, 2024. The balance of the settled hedged foreign currency forward contracts will be reclassified to earnings over the life of the related assets. See Note 17, “Restructuring Charges and Asset Write-offs,” and Note 22, “Fair Value of Financial Instruments,” for additional information. (b) The pre-tax portion of the amount reclassified from accumulated other comprehensive loss is included in interest expense. The balance of this interest rate swap was being amortized to Interest and financing expenses over the life of the 4.15% senior notes originally due in 2024. As discussed in Note 12, “Long-term Debt,” the Company repaid these notes in the second quarter of 2022, and as a result, reclassified the remaining balance of this interest rate swap to interest expense during the same period as part of the early extinguishment of debt.

Restructuring Charges and Asset

Restructuring Charges and Asset Write-Offs	12 Months Ended
	Dec. 31, 2024
Restructuring and Related Activities [Abstract]
Restructuring Charges and Asset Write-Offs	Restructuring Charges and Asset Write-offs: 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. As part of this review, the Company made the decision to stop construction of Kemerton conversion plant Train 3 in Western Australia and to 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. Kemerton Train 1 will continue to operate and activity around it is currently focused on commercialization efforts. The Company’s actions regarding Kemerton are 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 effort, effective November 1, 2024, the Company transitioned its operating structure to a fully integrated functional model (excluding Ketjen) from a global business unit model. As a result, the Company implemented a global workforce reduction that impacted 6-7% of total headcount during the second half of 2024. As a result of the above actions, the Company recorded charges in Cost of goods sold and Restructuring charges and asset write-offs for the year ended December 31, 2024 of $16.5 million and $762.6 million, respectively, consisting of the write-off of the carrying value of the Kemerton Train 3 assets less any salvage value, contract cancellation costs, decommissioning, demolition and other associated restructuring costs for both Kemerton Trains 2 and 3. The Company also recorded a loss of $20.7 million in Other income, net for the year ended December 31, 2024 related to the reclassification of the related dedesignated cash flow hedge from Accumulated other comprehensive loss. In addition, the Company recorded severance and employee benefit charges related to the above actions of $3.8 million and $47.5 million in Cost of goods sold and Restructuring charges and asset writeoffs, respectively, for the year ended December 31, 2024. The Company expects to record additional restructuring costs related to the Second Half 2024 Restructuring in the range of $35 million to $45 million in the year ended December 31, 2025, when the Company expects the actions to be substantially completed. First Half 2024 Restructuring In January 2024, the Company announced measures to unlock near-term cash flow and generate long-term financial flexibility by re-phasing organic growth investments and optimizing its cost structure. As part of these measures, during the second quarter of 2024, the Company indefinitely suspended construction of Kemerton Train 4, as well as deferred spending and investments with respect to certain other capital projects. The Company wrote-off the book value of assets related to these capital projects, which are no longer part of the Company’s modified capital plan, as it determined that these assets will not provide future value or will require significant re-engineering if the related projects are restarted, as well as recorded losses for associated contract cancellation costs. In addition, the Company recorded severance costs for employees in Corporate and each of the businesses as part of these announced measures. These actions resulted in charges of $324.3 million recorded in Restructuring charges and asset write-offs for the year ended December 31, 2024 and a loss of $5.4 million recorded in Other income, net for the year ended December 31, 2024 related to the reclassification of the related dedesignated cash flow hedge from Accumulated other comprehensive loss. No further costs associated with the First Half 2024 Restructuring are expected to be recorded as this restructuring plan was completed in the first half of 2024. 2023 Restructuring During the year ended December 31, 2023, $9.5 million of separation and other severance costs to employees in Corporate and the Ketjen business were recorded in Restructuring charges and asset write-offs. Detail of Restructuring Charges and Reserves The following table provides details of our restructuring related charges for the year ended December 31, 2024, which represent the cumulative amounts incurred to date for these plans (in thousands): Year Ended December 31, 2024 Asset Write-offs (a) Severance and Employee Benefits (b) Contract Cancellation Costs (c) Other (d) Total First Half 2024 Restructuring (e) $ 280,596 $ 18,856 $ 24,887 $ 5,374 $ 329,713 Second Half 2024 Restructuring (e) 732,907 51,264 37,370 29,552 851,093 $ 1,013,503 $ 70,120 $ 62,257 $ 34,926 $ 1,180,806 (a) Asset write-offs include $16.5 million recorded in Cost of goods sold, primarily related to work in process inventory with no future value as a result of the decomissioning of Kemerton Train 2 that was placed into care and maintenance.

Stock-based Compensation Expens

Stock-based Compensation Expense	12 Months Ended

Share-Based Payment Arrangement, Noncash Expense [Abstract]
Stock-based Compensation Expense	Stock-based Compensation Expense: Incentive Plans We have various share-based compensation plans that authorize the granting of (i) qualified and non-qualified stock options to purchase shares of our common stock, (ii) restricted stock and restricted stock units, (iii) performance unit awards and (iv) stock appreciation rights (“SARs”) to employees and non-employee directors, at our option. Stock options granted to employees generally vest over three years and have a term of ten years. Restricted stock and restricted stock unit awards vest in periods ranging from one one In May 2017, the Company adopted the Albemarle Corporation 2017 Incentive Plan (the “Incentive Plan”), which replaced the Albemarle Corporation 2008 Incentive Plan. The maximum number of shares available for issuance to participants under the Incentive Plan is 4,500,000 shares. The adoption of the Incentive Plan did not affect awards already granted under the Albemarle Corporation 2008 Incentive Plan. In February 2023, the Company adopted the Albemarle Corporation 2023 Stock Compensation and Deferral Election Plan for Non-Employee Directors (the “Non-Employee Directors Plan”). The Non-Employee Directors Plan replaced the 2013 Stock Compensation and Deferral Election Plan for Non-Employee Directors, which expired by its terms in May 2023. Under the Non-Employee Directors Plan, a maximum aggregate number of 500,000 shares of our common stock is authorized for issuance to the Company’s non-employee directors; any shares remaining available for issuance under the prior plans were canceled. The aggregate fair market value of shares that may be issued to a director during any compensation year (as defined in the Non-Employee Directors Plan, generally July 1 to June 30) shall not exceed $750,000. At December 31, 2024, there were 2,604,956 shares available for grant under the Incentive Plan and 477,440 shares available for grant under the Non-Employee Directors Plan. Total stock-based compensation expense associated with our incentive plans for the years ended December 31, 2024, 2023 and 2022 amounted to $33.1 million, $39.0 million and $31.4 million, respectively, and is included in Cost of goods sold and Selling, general and administrative expenses in the consolidated statements of (loss) income. Total related recognized tax benefits for the years ended December 31, 2024, 2023 and 2022 amounted to $2.7 million, $4.6 million and $4.0 million, respectively. The following table summarizes information about the Company’s fixed-price stock options as of and for the year ended December 31, 2024: Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at December 31, 2023 427,144 $ 129.59 5.8 $ 14,891 Granted 165,350 118.18 Exercised (6,570) 57.02 Forfeited (30,268) 141.91 Outstanding at December 31, 2024 555,656 $ 126.38 5.9 $ 1,255 Exercisable at December 31, 2024 316,658 $ 101.73 3.9 $ 1,255 We granted 165,350, 51,316 and 57,348 stock options during 2024, 2023 and 2022, respectively. There were no significant modifications made to any share-based grants during these periods. The fair value of each option granted during the years ended December 31, 2024, 2023 and 2022 was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions: Year Ended December 31, 2024 2023 2022 Dividend yield 1.43 % 1.26 % 1.32 % Volatility 42.44 % 40.06 % 36.21 % Average expected life (years) 6 6 6 Risk-free interest rate 4.33 % 3.95 % 1.97 % Fair value of options granted $ 48.70 $ 98.66 $ 63.00 Dividend yield is the average of historical yields and those estimated over the average expected life. The stock volatility is based on historical volatilities of our common stock. The average expected life represents the weighted average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and our historical exercise patterns. The risk-free interest rate is based on the U.S. Treasury strip rate with stripped coupon interest for the period equal to the contractual term of the share option grant in effect at the time of grant. The intrinsic value of options exercised during the years ended December 31, 2024, 2023 and 2022 was $0.3 million, $0.5 million and $6.9 million, respectively. The intrinsic value of a stock option is the amount by which the market value of the underlying stock exceeds the exercise price of the option. Total compensation cost not yet recognized for nonvested stock options outstanding as of December 31, 2024 is approximately $5.7 million and is expected to be recognized over a remaining weighted-average period of 1.6 years. Cash proceeds from stock options exercised and tax benefits related to stock options exercised were $0.4 million and $0.1 million for the year ended December 31, 2024, respectively. The Company issues new shares of common stock upon exercise of stock options and vesting of restricted common stock awards. The following table summarizes activity in performance unit awards as of and for the year ended December 31, 2024: Shares Weighted-Average Grant Date Fair Value Per Share Nonvested, beginning of period 223,856 $ 207.61 Granted 168,374 129.41 Vested (74,188) 133.87 Forfeited (41,014) 181.28 Nonvested, end of period 277,028 183.16 The weighted average grant date fair value of performance unit awards granted in 2024, 2023 and 2022 was $21.8 million, $22.9 million and $13.1 million, respectively. For all periods presented, half of the performance unit awards granted were based on the targeted return on invested capital (“ROIC Award”), while the other half were granted based on targeted market conditions (“TSR Award”). The fair value of each TSR Award was estimated on the date of grant using the Monte Carlo simulation model as these equity awards are tied to a service and market condition. The calculation used the following weighted-average assumptions: Year Ended December 31, 2024 2023 2022 Volatility 49.11 % 50.41 % 51.51 % Risk-free interest rate 4.41 % 4.51 % 1.72 % The weighted average fair value of performance unit awards that vested during 2024, 2023 and 2022 was $9.5 million, $17.2 million and $11.9 million, respectively, based on the closing prices of our common stock on the dates of vesting. Total compensation cost not yet recognized for nonvested performance unit awards outstanding as of December 31, 2024 is approximately $15.8 million, calculated based on current expectation of specific performance criteria, and is expected to be recognized over a remaining weighted-average period of approximately 1.9 years. Each performance unit represents one share of common stock. The following table summarizes activity in non-performance based restricted stock and restricted stock unit awards as of and for the year ended December 31, 2024: Shares Weighted-Average Grant Date Fair Value Per Share Nonvested, beginning of period 198,147 $ 190.40 Granted 137,436 111.78 Vested (88,032) 163.53 Forfeited (40,969) 169.87 Nonvested, end of period 206,582 152.75 The weighted average grant date fair value of restricted stock and restricted stock unit awards granted in 2024, 2023 and 2022 was $15.4 million, $19.4 million and $15.4 million, respectively. The weighted average fair value of restricted stock and restricted stock unit awards that vested in 2024, 2023 and 2022 was $10.0 million, $38.8 million and $17.8 million, respectively, based on the closing prices of our common stock on the dates of vesting. Total compensation cost not yet recognized for nonvested, non-performance based restricted stock and restricted stock units as of December 31, 2024 is approximately $14.2 million and is expected to be recognized over a remaining weighted-average period of 1.5 years. The fair value of the non-performance based restricted stock and restricted stock units was estimated on the date of grant adjusted for a dividend factor, if necessary.

In addition, the year ended December 31, 2024 includes benefits of $70.1 million due to the release of a foreign valuation allowance due to changes in expected profitability. (b) Our statutory rate is decreased by our share of the income of JBC, a Free Zones company under the laws of the Hashemite Kingdom of Jordan. The applicable provisions of the Jordanian law, and applicable regulations thereunder, do not have a termination provision and the exemption is indefinite. As a Free Zones company, JBC is not subject to income taxes on the profits of products exported from Jordan, and currently, substantially all of the profits are from exports. This resulted in a rate benefit of 1.2%, 20.1%, and 3.2% for the years ended December 31, 2024, 2023, and 2022, respectively. (c) The year ended December 31, 2024 includes a $37.0 million expense recorded for a current year tax reserve related to an uncertain tax position in Chile. Deferred income tax assets and liabilities recorded on the consolidated balance sheets as of December 31, 2024 and 2023 consist of the following (in thousands): December 31, 2024 2023 Deferred tax assets: Accrued employee benefits $ 32,993 $ 31,917 Operating loss carryovers 1,841,399 1,316,916 Pensions 17,148 23,527 Inventory reserves 27,974 83,136 Tax credit carryovers 11,228 1,431 Capitalized research and development 41,938 36,929 Lease liability 53,968 35,977 Other 62,406 30,611 Gross deferred tax assets 2,089,054 1,560,444 Valuation allowance (1,736,456) (1,349,924) Deferred tax assets 352,598 210,520 Deferred tax liabilities: Depreciation (456,231) (541,245) Intangibles (49,676) (54,413) Right of use asset (48,951) (30,336) Outside basis difference (51,971) (56,214) Other (50,190) (64,309) Deferred tax liabilities (657,019) (746,517) Net deferred tax liabilities $ (304,421) $ (535,997) Classification in the consolidated balance sheets: Noncurrent deferred tax assets $ 53,608 $ 22,433 Noncurrent deferred tax liabilities (358,029) (558,430) Net deferred tax liabilities $ (304,421) $ (535,997) Changes in the balance of our deferred tax asset valuation allowance are as follows (in thousands): Year Ended December 31, 2024 2023 2022 Balance at January 1 $ (1,349,924) $ (1,087,505) $ (1,276,305) Additions (519,169) (262,469) (5,810) Deductions 132,637 50 194,610 Balance at December 31 $ (1,736,456) $ (1,349,924) $ (1,087,505) At December 31, 2024, we had approximately $11.3 million of domestic credits available to offset future payments of income taxes, expiring in varying amounts between 2025 and 2029. We have established valuation allowances for $0.1 million of those domestic credits since we believe that it is more likely than not that the related deferred tax assets will not be realized. We believe that sufficient taxable income will be generated during the carryover period in order to utilize the other remaining credit carryovers. At December 31, 2024, we have on a pre-tax basis, domestic federal and state net operating losses of $1.1 billion, which have pre-tax valuation allowances of $13.8 million established. $0.5 billion of these domestic net operating losses expire between 2025 and 2041 and $0.6 billion have no expiration date. In addition, we have on a pre-tax basis $6.7 billion of foreign net operating losses, which have pre-tax valuation allowances for $6.6 billion established. $636.4 million of these foreign net operating losses expire in 2028, $1.3 billion expire in 2029, $2.6 billion expire in 2035, $203.2 million expire in 2036, $19.3 million expire in 2037 and $1.8 billion have an indefinite life. We have established valuation allowances for these deferred tax assets since we believe that it is more likely than not that the related deferred tax assets will not be realized. For the same reason, we established pre-tax valuation allowances of $215.3 million and $15.3 million for other state and foreign deferred tax assets, respectively, unrelated to net operating losses. The realization of the deferred tax assets is dependent on the generation of sufficient taxable income in the appropriate tax jurisdictions. Although realization is not assured, we believe it is more likely than not that the remaining deferred tax assets will be realized. However, the amount considered realizable could be reduced if estimates of future taxable income change. As of December 31, 2024, we have not recorded taxes on approximately $12.2 billion of cumulative undistributed earnings of our non-U.S. subsidiaries and joint ventures. The TCJA imposed a mandatory transition tax on accumulated foreign earnings and generally eliminated U.S. taxes on foreign subsidiary distribution with the exception of foreign withholding taxes and other foreign local tax. We generally do not provide for taxes related to our undistributed earnings because such earnings either would not be taxable when remitted or they are considered to be indefinitely reinvested. If in the foreseeable future, we can no longer demonstrate that these earnings are indefinitely reinvested, a deferred tax liability will be recognized. A determination of the amount of the unrecognized deferred tax liability related to these undistributed earnings is not practicable due to the complexity and variety of assumptions necessary based on the manner in which the undistributed earnings would be repatriated. Liabilities related to uncertain tax positions were $259.6 million and $220.6 million at December 31, 2024 and 2023, respectively, inclusive of interest and penalties of $71.0 million and $42.0 million at December 31, 2024 and 2023, respectively, and are reported in Other noncurrent liabilities as provided in Note 14, “Other Noncurrent Liabilities.” These liabilities at December 31, 2024 and 2023 were reduced by $74.8 million and $73.0 million, respectively, for offsetting benefits from the corresponding effects of potential transfer pricing adjustments, state and local income taxes, and rate arbitrage related to foreign structure. These offsetting benefits are recorded in Other assets as provided in Note 9, “Other Assets.” The resulting net liability of $113.8 million, excluding interest and penalties, as of December 31, 2024 would favorably affect earnings if recognized and released, as would the net liability of $105.6 million, excluding interest and penalties, have as of December 31, 2023. The liabilities related to uncertain tax positions, exclusive of interest, were $188.8 million and $178.8 million at December 31, 2024 and 2023, respectively. The following is a reconciliation of our total gross liability related to uncertain tax positions for 2024, 2023 and 2022 (in thousands): Year Ended December 31, 2024 2023 2022 Balance at January 1 $ 178,785 $ 72,162 $ 20,717 Additions for tax positions related to prior years 31 6,216 1,673 Reductions for tax positions related to prior years — — — Additions for tax positions related to current year 10,989 101,179 50,531 Lapses in statutes of limitations/settlements (1,038) (770) (995) Foreign currency translation adjustment 59 (2) 236 Balance at December 31 $ 188,826 $ 178,785 $ 72,162 We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Due to the statute of limitations, we are no longer subject to U.S. federal income tax audits by the Internal Revenue Service (“IRS”) for years prior to 2021. Due to the statute of limitations, we also are no longer subject to U.S. state income tax audits prior to 2018. With respect to jurisdictions outside the U.S., several audits are in process. We have audits ongoing for the years 2014 through 2023 related to Belgium, Canada, Chile, China and Germany, some of which are for entities that have since been divested. While we believe we have adequately provided for all tax positions, amounts asserted by taxing authorities could be greater than our accrued position. Accordingly, additional provisions on federal and foreign tax-related matters could be recorded in the future as revised estimates are made or the underlying matters are settled or otherwise resolved. Since the timing of resolutions and/or closure of tax audits is uncertain, it is difficult to predict with certainty the range of reasonably possible significant increases or decreases in the liability related to uncertain tax positions that may occur within the next twelve months.

At December 31, 2024, there were 14,000 unvested shares of restricted stock awards outstanding. We have the authority to issue 15,000,000 shares of preferred stock in one or more classes or series. As of December 31, 2024, 2,300,000 shares of preferred stock have been issued. In November 2016, our Board of Directors authorized an increase in the number of shares the Company is permitted to repurchase under our share repurchase program, pursuant to which the Company is now permitted to repurchase up to a maximum of 15,000,000 shares, including those previously authorized but not yet repurchased. There were no shares of the Company’s common stock repurchased during the years ended December 31, 2024, 2023 or 2022. As of December 31, 2024, there were 7,396,263 remaining shares available for repurchase under the Company’s authorized share repurchase program.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments: In assessing the fair value of financial instruments, we use methods and assumptions that are based on market conditions and other risk factors existing at the time of assessment. Fair value information for our financial instruments is as follows: Long-Term Debt—the fair values of our 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 our 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. December 31, 2024 2023 Recorded Amount Fair Value Recorded Amount Fair Value (In thousands) Long-term debt $ 3,532,713 $ 3,332,064 $ 4,186,532 $ 4,021,693 During the fourth quarter of 2019, we entered into a foreign currency forward contract to hedge the cash flow exposure of non-functional currency purchases during the construction of the Kemerton plant in Australia. This derivative financial instrument is used to manage risk and is not used for trading or other speculative purposes. This foreign currency forward contract has been designated as a hedging instrument under ASC 815, Derivatives and Hedging . As a result of the actions taken at Kemerton Trains 3 and 4 during 2024, the Company dedesignated the remaining hedged foreign currency forward contracts. The Company recorded a loss in Other income, net of $26.1 million during the year ended December 31, 2024 from the reclassification of the hedged balance from Accumulated other comprehensive loss. The balance of the settled hedged foreign currency forward contracts associated with the construction of Kemerton Trains 1 and 2 assets placed into service will be reclassified to earnings over the life of the related assets. At December 31, 2023, the notional value of these outstanding designated foreign currency forward contracts totaled the equivalent of $994.5 million. In connection with our risk management strategies, we also enter into other 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 December 31, 2024 and 2023, we had outstanding non-designated derivative financial instruments with notional values totaling $6.9 billion and $7.1 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 December 31, 2024, these foreign currency forward contracts hedge our exposure to various currencies including the Chinese Renminbi, Euro and Australian Dollar. The following table summarizes the fair value of our derivative financial instruments included in the consolidated balance sheets at December 31, 2024 and 2023 (in thousands): December 31, 2024 2023 Assets Liabilities Assets Liabilities Designated as hedging instruments Other current assets $ — $ — $ 3,489 $ — Other assets — — 11,704 — Accrued expenses — — — 446 Total designated as hedging instruments — — 15,193 446 Not designated as hedging instruments Other current assets 4,347 — 2,636 — Accrued expenses — 6,586 — 5,306 Other noncurrent liabilities — 4,766 — — Total not designated as hedging instruments 4,347 11,352 2,636 5,306 Total $ 4,347 $ 11,352 $ 17,829 $ 5,752 The following table summarizes the net (losses) gains recognized for our derivative financial instruments during the years ended December 31, 2024, 2023 and 2022 (in thousands): Year Ended December 31, 2024 2023 2022 Designated as hedging instruments: (Loss) gain recognized in Other comprehensive (loss) income $ (28,701) $ 5,986 $ (4,399) (Loss) gain recognized in Other income, net $ (25,766) $ 135 $ — Not designated as hedging instruments: (Loss) gain recognized in Other income, net (a) $ (14,728) $ 213,378 $ (41,088) (a) Fluctuations in the value of our foreign currency forward contracts not designated as hedging instruments are generally expected to be offset by changes in the value of the underlying exposures being hedged, which are also reported in Other income, net. In addition, for the years ended December 31, 2024, 2023 and 2022, we recorded net cash (settlements) receipts of ($9.8) million, $218.0 million and ($44.4) million, respectively, primarily within Changes in current assets and liabilities, in our consolidated statements of cash flows. Unrealized gains and losses related to the cash flow hedges will be reclassified to earnings over the life of the related assets when settled and the related assets are placed into service. 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 1 Unadjusted quoted prices in active markets for identical assets or liabilities Level 2 Unadjusted 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 3 Unobservable 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 December 31, 2024 and 2023 (in thousands): December 31, 2024 Quoted Prices in Active Markets for Identical Items (Level 1) Quoted Prices in Active Markets for Similar Items (Level 2) Unobservable Inputs (Level 3) Assets: Available for sale debt securities (a) $ 313,991 $ — $ — $ 313,991 Investments under executive deferred compensation plan (b) $ 38,243 $ 38,243 $ — $ — Public equity securities (c) $ 17,910 $ 17,910 $ — $ — Private equity securities measured at net asset value (d)(e) $ 4,472 $ — $ — $ — Derivative financial instruments (f) $ 4,347 $ — $ 4,347 $ — Liabilities: Obligations under executive deferred compensation plan (b) $ 38,243 $ 38,243 $ — $ — Derivative financial instruments (f) $ 11,352 $ — $ 11,352 $ — December 31, 2023 Quoted Prices in Active Markets for Identical Items (Level 1) Quoted Prices in Active Markets for Similar Items (Level 2) Unobservable Inputs (Level 3) Assets: Available for sale debt securities (a) $ 289,307 $ — $ — $ 289,307 Investments under executive deferred compensation plan (b) $ 33,564 $ 33,564 $ — $ — Public equity securities (c) $ 168,928 $ 168,928 $ — $ — Private equity securities measured at net asset value (d)(e) $ 4,536 $ — $ — $ — Derivative financial instruments (f) $ 17,829 $ — $ 17,829 $ — Liabilities: Obligations under executive deferred compensation plan (b) $ 33,564 $ 33,564 $ — $ — Derivative financial instruments (f) $ 5,752 $ — $ 5,752 $ — (a) Preferred equity of a Grace subsidiary acquired as a portion of the proceeds of the FCS sale on June 1, 2021. A third-party estimate of the fair value was prepared using expected future cash flows over the period up to when the asset is likely to be redeemed, applying a discount rate that appropriately captures a market participant's view of the risk associated with the investment. These are considered to be Level 3 inputs. (b) We maintain an EDCP that was adopted in 2001 and subsequently amended. 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 (loss) income) and cash and cash equivalents. As such, these assets and obligations are classified within Level 1. (c) Holdings in equity securities of public companies 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, net, in our consolidated statements of (loss) income. See Note 8, “Investments,” for further details. (d) Primarily consists of private equity securities reported in Investments in the consolidated balance sheets. The changes in fair value are reported in Other income, net in our consolidated statements of (loss) income. (e) Holdings in certain private equity securities 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. (f) The derivative financial instruments are primarily comprised of foreign currency forward contracts. As a result of our global operating and financing activities, we are exposed to market risks from changes in foreign currency exchange rates which may adversely affect our operating results and financial position. When deemed appropriate, we minimize our risks from foreign currency exchange rate fluctuations through the use of foreign currency forward contracts. The foreign currency forward contracts 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 22, “Fair Value of Financial Instruments,” for further details about our foreign currency forward contracts. The following tables set forth the reconciliation of the beginning and ending balance for the Level 3 recurring fair value measurements (in thousands): Available for Sale Debt Securities Year Ended December 31, 2024 2023 Beginning balance $ 289,307 $ 260,139 Accretion of discount — 5,306 PIK dividends 36,311 19,307 Change in fair value — 4,555 Cash received for tax liability (11,627) — Ending balance $ 313,991 $ 289,307

Segment Reporting [Abstract]
Segment and Geographic Area Information	Segment and Geographic Area Information: The Company has three operating and reportable segments, which are: (1) Energy Storage; (2) Specialties; and (3) Ketjen. 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 category is not considered to be a segment and includes corporate-related items not allocated to the operating segments. 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 process. 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. Effective January 1, 2024, the Company changed its definition of adjusted EBITDA for financial accounting purposes. The updated definition includes Albemarle’s share of the pre-tax earnings of the Windfield joint venture, whereas the prior definition included Albemarle’s share of Windfield earnings net of tax. This calculation is consistent with the definition of adjusted EBITDA used in the leverage financial covenant calculation in the amended 2022 Credit Agreement, which is a material agreement for the Company and aligns the information presented to various stakeholders. This presentation more closely represents the materiality and financial contribution of the strategic investment in Windfield to the Company’s earnings, and more closely represents a measure of EBITDA. The Company’s updated 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, facility divestiture charges, certain litigation and arbitration costs and charges, non-operating pension and OPEB items and other significant non-recurring items. Adjusted EBITDA for the prior periods has been recast to conform to the current year presentation. See below for a reconciliation of segment Net sales to adjusted EBITDA by segment showing significant segment expenses regularly reviewed by the CODM for the years ended December 31, 2024, 2023 and 2022 (in thousands): Energy Storage Specialties Ketjen Total Segments Year Ended December 31, 2024 Net sales (a) $ 3,015,121 $ 1,325,983 $ 1,036,422 $ 5,377,526 Cost of goods sold (b) (2,992,566) (935,017) (810,319) (4,737,902) Selling, general and administrative expenses (b) (249,805) (93,533) (90,653) (433,991) Other segment items (c) (25,101) (25,676) (26,852) (77,629) Equity in net income of unconsolidated investments (d) 1,009,891 — 22,468 1,032,359 Net income attributable to noncontrolling interests — (43,253) — (43,253) Adjusted EBITDA by segment $ 757,540 $ 228,504 $ 131,066 $ 1,117,110 Year Ended December 31, 2023 Net sales (a) $ 7,078,998 $ 1,482,425 $ 1,055,780 $ 9,617,203 Cost of goods sold (b) (6,205,403) (961,177) (847,018) (8,013,598) Selling, general and administrative expenses (b) (266,190) (100,173) (94,387) (460,750) Other segment items (c) (22,632) (25,719) (30,972) (79,323) Equity in net income of unconsolidated investments (d) 2,596,820 — 20,469 2,617,289 Net income attributable to noncontrolling interests — (96,850) — (96,850) Adjusted EBITDA by segment $ 3,181,593 $ 298,506 $ 103,872 $ 3,583,971 Year Ended December 31, 2022 Net sales (a) $ 4,660,945 $ 1,759,587 $ 899,572 $ 7,320,104 Cost of goods sold (b) (2,170,867) (1,013,247) (775,717) (3,959,831) Selling, general and administrative expenses (b) (186,311) (77,382) (84,896) (348,589) Other segment items (c) (18,389) (16,677) (32,131) (67,197) Equity in net income of unconsolidated investments (d) 1,066,978 — 21,904 1,088,882 Net income attributable to noncontrolling interests — (124,963) — (124,963) Adjusted EBITDA by segment $ 3,352,356 $ 527,318 $ 28,732 $ 3,908,406 (a) Intersegment sales are not considered material. (b) The significant expense categories and amounts align with the segment information that is regularly provided to the CODM. Excludes depreciation and amortization, and non-operating, non-recurring or unusual items as described in the reconciliation of total segment adjusted EBITDA to consolidated Net (loss) income attributable to Albemarle Corporation below. (c) Other segment items are comprised of Research and development expenses excluding depreciation and amortization. (d) Excludes Albemarle’s 49% ownership interest in the income tax expense of the Windfield joint venture. The Company reconciles the total segment adjusted EBITDA to the consolidated net (loss) income attributable to Albemarle Corporation given the impact of equity in net income from unconsolidated investments, the majority of which relates to the Windfield joint venture. This reconciliation reflects the strategic and operational significance of the Company’s joint ventures and aligns with our allocation of equity in net income from unconsolidated investments at the segment level, representing each segment's contribution to the Company's overall financial performance.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Albemarle recognizes the importance of maintaining the security and integrity of our information systems and the data we collect, process, and store. We have implemented a comprehensive cybersecurity program based on the National Institute of Standards and Technology Cybersecurity Framework (“CSF”). As such, we map the CSF to corresponding legal, regulatory, and industry security practices, which guide our global policies and procedures to prevent, identify, protect, detect, respond, and recover from cybersecurity threats and incidents. Our cybersecurity program is managed by our Cybersecurity Director and is overseen by our Chief Information Officer (“CIO”), who assumes responsibility for the Chief Information Security Officer (“CISO”) role. The cybersecurity program is integrated into our overall enterprise risk management framework and thus is factored into our long-term strategy and business continuity plans. Our Cybersecurity Director brings extensive experience in cybersecurity, including service in U.S. Army Cyber Operations, and has led initiatives in threat management, risk mitigation, and security architecture to strengthen enterprise resilience. His expertise in incident response and security strategy ensures our cybersecurity program remains aligned with industry best practices and evolving cyber threats. The Audit and Finance Committee (“AFC”) of our Board of Directors oversees information security matters and the Company’s cybersecurity program. Our CIO reports on cybersecurity related matters, including the status of ongoing initiatives, incident reporting, compliance with regulatory requirements and industry standards, and emerging threats in global cybersecurity, on an as needed basis, but at least annually, to the AFC and executive leadership. The AFC and executive leadership offer guidance on certain matters and approval for material initiatives. In addition, the full Board of Directors is updated on cybersecurity matters as needed depending on the nature and materiality of a cybersecurity matter. All information assets are inventoried, classified, prioritized, and protected based on the respective risk, with appropriate cybersecurity controls applied to each. We have also implemented and maintain a documents management program which governs the classification, protection, and use of sensitive company data within the Albemarle environment. All business-requested technologies and third-party service providers must successfully complete a thorough cybersecurity and contract review before being approved for use, after which they are continuously monitored as part of our supply chain risk management program. Cybersecurity risks and potential costs are evaluated as a part of business operations, and the respective business impacts are continuously assessed to address evolving threats and vulnerabilities. We engage a third-party global firm to conduct an annual cyber assessment using the CSF, and we engage external vendors to validate our security controls and procedures through periodic penetration tests. We follow a zero-trust architecture approach and enforce the use of multi-factor authentication and virtual private network technologies for all external access to provide secure support for our remote workers. Information security training is part of our compliance program, and includes mandatory security training for new hires, mandatory yearly security training for all staff, and periodic phishing tests to raise awareness and response actions. Our team of cybersecurity professionals are responsible for maintaining a global information systems environment that focuses on least privilege, least functionality, and network segmentation throughout the landscape using a layered approach (i.e. a defense-in-depth strategy). This includes a security operations center and cybersecurity analysts who provide 24/7 network monitoring. As further discussed in Item 1A. Risk Factors, a material cybersecurity incident could significantly increase the cost of doing business or otherwise adversely impact our financial results and condition. To date we have not had a cybersecurity incident that has had, or is reasonably likely to have, a material effect on our financial results or business operations; however, we monitor and work to continuously improve our cybersecurity program as threats become more frequent and sophisticated. Our manufacturing sites have formal business continuity plans that address site-specific priority responses, each determined through business impact analyses that integrate within our overall corporate crisis management response plan and enterprise risk management program. We conduct an annual incident response tabletop exercise as well as periodic exercises of formalized site business continuity plans. Lessons learned from the outcomes of these exercises are then assessed and used to inform and improve our formal cyber response procedures and business continuity plans. In the event of, or the reasonably likely threat of, a cybersecurity incident, our cyber response procedures outline the tasks and timeline for the escalation of the incident to key members of the organization, including the information technology team, business unit management, and Albemarle executives and other key management. These individuals would participate in a special event management plan activation meeting to gain an understanding as to how the incident was detected and analysis of the incident. Each member of management involved would be responsible for assessing the risks, impact, and necessary response as determined by their role. The procedures include key considerations each manager should consider in their assessment as well as their responsibility for involvement in remediation efforts and post-incident strategic reviews. Specific legal and executive role procedures include the assessment of necessary internal communication and external reporting. The Chief Executive Officer, with the support of other executive officers, is responsible for approval of incident reporting and informing and updating the Board of Directors.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation The consolidated financial statements include the accounts and operations of Albemarle Corporation and our wholly owned, majority owned and controlled subsidiaries. Unless the context otherwise indicates, the terms “Albemarle,” “we,” “us,” “our” or “the Company” mean Albemarle Corporation and its consolidated subsidiaries. For entities that we control and are the primary beneficiary, but own less than 100%, we record the minority ownership as noncontrolling interest, except as noted below. We apply the equity method of accounting for investments in which we have an ownership interest from 20% to 50% or where we exercise significant influence over the related investee’s operations. In addition, the consolidated financial statements contained herein include our proportionate share of the results of operations of the MARBL Lithium Joint Venture (“MARBL”), which manages the exploration, development, mining, processing and production of lithium and other minerals from the Wodgina hard rock lithium mine project (“Wodgina”). As described in Note 8, “Investments,” the Company closed on the restructuring of the MARBL joint venture with Mineral Resources Limited (“MRL”) on October 18, 2023 to reduce our ownership interest in the MARBL joint venture to 50% from 60%. The consolidated financial statements reflect our ownership percentage of the MARBL joint venture during the periods presented. The joint venture is unincorporated with each investor holding an undivided interest in each asset and proportionately liable for each liability; therefore our proportionate share of assets, liabilities, revenue and expenses are included in the appropriate classifications in the consolidated financial statements. All significant intercompany accounts and transactions are eliminated in consolidation. Cost of goods sold for the year ended December 31, 2024 includes income of $17.4 million for the correction of out of period errors pertaining to an overstated accrual for a profit sharing arrangement with the partner of one of the Company’s joint ventures. For the year ended December 31, 2023, Cost of goods sold was overstated by $17.4 million. The Company believes this adjustment is not material to the consolidated financial statements for the prior period presented, or for the current periodd, in which the correction was made.
Estimates, Assumptions and Reclassifications	Estimates, Assumptions and Reclassifications The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) requires management to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods and is recognized when performance obligations are satisfied under the terms of contracts with our customers. A performance obligation is deemed to be satisfied when control of the product is transferred to our customer. The transaction price of a contract, or the amount we expect to receive upon satisfaction of all performance obligations, is determined by reference to the contract’s terms and includes adjustments, if applicable, for any variable consideration, such as customer rebates, noncash consideration or consideration payable to the customer, although these adjustments are generally not material. Where a contract contains more than one distinct performance obligation, the transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation, although these situations are rare and are generally not built into our contracts. Any unsatisfied performance obligations are not material. Standalone selling prices are based on prices we charge to our customers, which in some cases are based on established market prices. Sales and other similar taxes collected from customers on behalf of third parties are excluded from revenue. Our payment terms are generally between 30 to 90 days, however, they vary by market factors, such as customer size, creditworthiness, geography and competitive environment. All of our revenue is derived from contracts with customers, and almost all of our contracts with customers contain one performance obligation for the transfer of goods where such performance obligation is satisfied at a point in time. Control of a product is deemed to be transferred to the customer upon shipment or delivery. Significant portions of our sales are sold free on board shipping point or on an equivalent basis, while delivery terms of other transactions are based upon specific contractual arrangements. Our standard terms of delivery are generally included in our contracts of sale, order confirmation documents and invoices, while the timing between shipment and delivery generally ranges between 1 and 45 days. Costs for shipping and handling activities, whether performed before or after the customer obtains control of the goods, are accounted for as fulfillment costs. Such costs are immaterial. The Company currently utilizes the following practical expedients, as permitted by Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers : • All sales and other pass-through taxes are excluded from contract value; • In utilizing the modified retrospective transition method, no adjustment was necessary for contracts that did not cross over the reporting year; • We will not consider the possibility of a contract having a significant financing component (which would effectively attribute a portion of the sales price to interest income) unless, if at contract inception, the expected payment terms (from time of delivery or other relevant criterion) are more than one year; • If our right to customer payment is directly related to the value of our completed performance, we recognize revenue consistent with the invoicing right; and • We expense as incurred all costs of obtaining a contract incremental to any costs/compensation attributable to individual product sales/shipments for contracts where the amortization period for such costs would otherwise be one year or less. Costs incurred to obtain contracts with customers are not significant and are expensed immediately as the amortization period would be one year or less. When the Company incurs pre-production or other fulfillment costs in connection with an existing or specific anticipated contract and such costs are recoverable through margin or explicitly reimbursable, such costs are capitalized and amortized to Cost of goods sold on a systematic basis that is consistent with the pattern of transfer to the customer of the goods or services to which the asset relates, which is less than one year. We record bad debt expense in specific situations when we determine the customer is unable to meet its financial obligation. Included in Trade accounts receivable at December 31, 2024 and 2023 is approximately $705.8 million and $1.2 billion, respectively, arising from contracts with customers. The remaining balance of Trade accounts receivable at December 31, 2024 and 2023 primarily includes value-added taxes collected from customers on behalf of various taxing authorities.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and money market investments with insignificant interest rate risks and no limitations on access.
Inventories	Inventories Inventories are stated at lower of cost and net realizable value with cost determined using standard cost, which approximates the first-in, first-out basis. Cost is determined on the weighted-average basis for a small portion of our inventories at foreign plants and our stores, supplies and other inventory. A portion of our domestic produced finished goods and raw materials are determined on the last-in, first-out basis. The Company eliminates the balance of intra-entity profits on purchases of inventory from its equity method investments that remains unsold at the balance sheet in Inventories, specifically finished goods and equally reduces Equity in net income of unconsolidated investments (net of tax) on the consolidated statements of (loss) income. 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 (loss) income.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment include costs of assets constructed, purchased or leased under a finance lease, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for normal repairs and maintenance are expensed as incurred. Costs associated with yearly planned major maintenance are generally deferred and amortized over 12 months or until the same major maintenance activities must be repeated, whichever is shorter. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in income. We assign the useful lives of our property, plant and equipment based upon our internal engineering estimates, which are reviewed periodically. The estimated useful lives of our property, plant and equipment range from two We evaluate the recovery of our property, plant and equipment annually and when events or changes in circumstances indicate that its carrying amount may not be recoverable. Events that may trigger a test for recoverability include, but are not limited to, significant adverse changes to projected revenues, costs, or capital plans or changes to government regulations that may adversely impact our current or future operations. An impairment is determined to exist if the total projected future cash flows on an undiscounted basis are not recoverable or are less than the carrying amount of a long-lived asset group. We estimate future cash flows based on numerous assumptions, which are consistent or reasonable in relation to internal budgets and projections, and actual future cash flows may be significantly different than the estimates. Significant estimates used include, but are not limited to, market pricing (including lithium index pricing), customer demand, operating and production costs, and the timing and capital costs of expansion and sustaining projects. Significant management judgment is involved in estimating these variables and they include inherent uncertainties since they are forecasting future events.
Leases	Leases We determine if an arrangement is a lease at inception. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As an implicit rate for most of our leases is not determinable, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease payments for the initial measurement of lease ROU assets and lease liabilities include fixed and variable payments based on an index or a rate. Variable lease payments that are not index or rate based are recorded as expenses when incurred. Our variable lease payments typically include real estate taxes, insurance costs and common-area maintenance. The operating lease ROU asset also includes any lease payments made, net of lease incentives. The lease term is the non-cancelable period of the lease, including any options to extend, purchase or terminate the lease when it is reasonably certain that we will exercise that option. We amortize the operating lease ROU assets on a straight-line basis over the period of the lease and the finance lease ROU assets on a straight-line basis over the shorter of their estimated useful lives or the lease terms. 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. Additionally, we have made accounting policy elections such as exclusion of short-term leases (leases with a term of 12 months or less and which do not include a purchase option that we are reasonably certain to exercise) from the balance sheet presentation, use of portfolio approach in determination of discount rate and accounting for non-lease components in a contract as part of a single lease component for all asset classes, except specific mining operation equipment.
Resource Development Expenses	Resource Development Expenses We incur costs in resource exploration, evaluation and development during the different phases of our resource development projects. Exploration costs incurred before the declaration of proven and probable resources are generally expensed as incurred. After proven and probable resources are declared, exploration, evaluation and development costs necessary to bring the property to commercial capacity or increase the capacity or useful life are capitalized. Any costs to maintain the production capacity in a property under production are expensed as incurred. Capitalized resource costs are depleted using the units-of-production method. Our resource development assets are evaluated for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable.
Investments	Investments Investments are accounted for using the equity method of accounting if the investment gives us the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of the investee between 20% and 50%, although other factors, such as representation on the investee’s board of directors and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting, we record our investments in equity-method investees in the consolidated balance sheets as Investments and our share of investees’ earnings or losses together with other-than-temporary impairments in value as Equity in net income of unconsolidated investments in the consolidated statements of (loss) income. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. Certain investments in equity securities and mutual fund investments are accounted for as trading equities and are marked-to-market on a periodic basis through the consolidated statements of (loss) income. Investments in joint ventures and nonmarketable securities of immaterial entities are estimated based upon the overall performance of the entity where financial results are not available on a timely basis.
Environmental Compliance and Remediation	Environmental Compliance and Remediation Environmental compliance costs include the cost of purchasing and/or constructing assets to prevent, limit and/or control pollution or to monitor the environmental status at various locations. These costs are capitalized and depreciated based on estimated useful lives. Environmental compliance costs also include maintenance and operating costs with respect to pollution prevention and control facilities and other administrative costs. Such operating costs are expensed as incurred. Environmental remediation costs of facilities used in current operations are generally immaterial and are expensed as incurred. We accrue for environmental remediation costs and post-remediation costs that relate to existing conditions caused by past operations at facilities or off-plant disposal sites in the accounting period in which responsibility is established and when the related liability is considered probable and estimable. In developing these cost estimates, we evaluate currently available facts regarding each site, with consideration given to existing technology, presently enacted laws and regulations, prior experience in remediation of contaminated sites, the financial capability of other potentially responsible parties and other factors, subject to uncertainties inherent in the estimation process. If the amount and timing of the cash payments for a site are fixed or reliably determinable, the liability is discounted, if the calculated discount is material. Additionally, these estimates are reviewed periodically, with adjustments to the accruals recorded as necessary.
Research and Development Expenses	Research and Development Expenses Our research and development expenses related to present and future products are expensed as incurred. These expenses consist primarily of personnel-related costs and other overheads, as well as outside service and consulting costs incurred for specific programs. Our U.S. facilities in Texas and Louisiana and our global facilities in the Netherlands, Germany, Belgium and Korea form the capability base for our contract research and custom manufacturing businesses. These business areas provide research and scale-up services primarily to innovative life science companies.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets We account for goodwill and other intangibles acquired in a business combination in conformity with current accounting guidance that requires that goodwill and indefinite-lived intangible assets not be amortized. We test goodwill for impairment by comparing the estimated fair value of our reporting units to the related carrying value. Our reporting units are either our operating business segments or one level below our operating business segments for which discrete financial information is available and for which operating results are regularly reviewed by the business management. In applying the goodwill impairment test, the Company initially performs a qualitative test (“Step 0”), where it first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting units is less than its carrying value. Qualitative factors may include, but are not limited to, economic conditions, industry and market considerations, cost factors, overall financial performance of the reporting units and other entity and reporting unit specific events. If after assessing these qualitative factors, the Company determines it is “more-likely-than-not” that the fair value of the reporting unit is less than the carrying value, the Company performs a quantitative test (“Step 1”). During Step 1, the Company estimates the fair value using either a discounted cash flow model (income) approach or a combination of the discounted cash flow model (income) approach and earnings multiple (market) approach (placing equal weighting on the income and market approaches). The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to the projected earnings of the reporting unit. Future cash flows for all reporting units include assumptions about revenue growth rates, adjusted EBITDA margins, discount rate as well as other economic or industry-related factors. The Company defines adjusted EBITDA as 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. For the Refining Solutions reporting unit, within the Ketjen segment, the revenue growth rates, adjusted EBITDA margins, EBITDA multiples, market participant acquisition premium and the discount rate were deemed to be significant assumptions. For the Energy Storage reporting unit, the revenue growth rates, adjusted EBITDA margins and the discount rate were deemed to be significant assumptions. Significant management judgment is involved in estimating these variables and they include inherent uncertainties, particularly regarding future market conditions and cost fluctuations. Any adverse changes in these assumptions, such as a decline in demand, increased competition, rising costs or the imposition of new tariffs could negatively impact the fair value of the reporting units, since they are forecasting future events. The Company uses a Weighted Average Cost of Capital (“WACC”) approach to determine our discount rate for goodwill recoverability testing. The WACC calculation incorporates industry-weighted average returns on debt and equity from a market perspective. The factors in this calculation are largely external to the Company and, therefore, are beyond its control. The Company performs a sensitivity analysis by using a range of inputs to confirm the reasonableness of these estimates being used in the goodwill impairment analysis. The Company tests its recorded goodwill for impairment in the fourth quarter of each year or upon the occurrence of events or changes in circumstances that would more likely than not reduce the fair value of its reporting units below their carrying amounts. In July 2024, the Company made the decision to stop construction of Kemerton conversion plant Train 3 and put Kemerton Train 2 into care and maintenance. See Note 17, “Restructuring Charges and Asset Write-offs,” for further details. The Company determined these actions to be a triggering event for a review for impairment of its Energy Storage reporting unit goodwill. As a result, during the third quarter of 2024, the Company tested the goodwill of the Energy Storage reporting unit by comparing its estimated fair value, using a discounted cash flow model, to the related carrying value. Based on the analysis, the Energy Storage reporting unit had sufficient headroom, which is defined as the percentage difference between the fair value of a reporting unit and its carrying value, that reasonable differences in the significant assumptions used would not impact the conclusion. Consequently, the Company concluded that the Energy Storage estimated fair value exceeded its carrying value, thus no impairment was recorded in the third quarter of 2024. The Company performed its annual goodwill impairment test as of October 31, 2024. No evidence of impairment was noted for the reporting units with goodwill balances from the analysis. In addition, there were no triggering events subsequent to the annual goodwill impairment test for any of the reporting units. However, if the adjusted EBITDA or discount rate estimates for the Refining Solutions reporting unit negatively changed by 10% (absent any other changes), the Refining Solutions fair value would be below its carrying value. Potential events and changes in circumstances that could reasonably be expected to negatively affect the key assumptions include reductions in demand in oilfield markets, inability to implement effective pricing actions to offset cost increases, changes in macroeconomic conditions and the introduction or escalation of tariffs on imported materials. The Company will continue to monitor these factors closely and assess their impact on its goodwill impairment evaluations in future periods. The Company assesses its indefinite-lived intangible assets, which include trade names and trademarks, for impairment annually and between annual tests if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. The indefinite-lived intangible asset impairment standard allows the Company to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if we determine, based on the qualitative assessment, that it is more likely than not that the indefinite-lived intangible asset’s fair value is less than its carrying amount. If we determine based on the qualitative assessment that it is more likely than not that the asset is impaired, an impairment test is performed by comparing the fair value of the indefinite-lived intangible asset to its carrying amount. During the year ended December 31, 2024, no evidence of impairment was noted from the analysis for the Company’s indefinite-lived intangible assets. Definite-lived intangible assets, such as purchased technology, patents and customer lists, are amortized over their estimated useful lives generally for periods ranging from five
Pension Plans and Other Postretirement Benefits	Pension Plans and Other Postretirement Benefits Under authoritative accounting standards, assumptions are made regarding the valuation of benefit obligations and the performance of plan assets. As required, we recognize a balance sheet asset or liability for each of our pension and other postretirement benefit (“OPEB”) plans equal to the plan’s funded status as of the measurement date. The primary assumptions are as follows: • Discount Rate—The discount rate is used in calculating the present value of benefits, which is based on projections of benefit payments to be made in the future. • Expected Return on Plan Assets—We project the future return on plan assets based on prior performance and future expectations for the types of investments held by the plans, as well as the expected long-term allocation of plan assets for these investments. These projected returns reduce the net benefit costs recorded currently. • Rate of Compensation Increase—For salary-related plans, we project employees’ annual pay increases, which are used to project employees’ pension benefits at retirement. • Mortality Assumptions—Assumptions about life expectancy of plan participants are used in the measurement of related plan obligations. Actuarial gains and losses are recognized annually in our consolidated statements of (loss) income in the fourth quarter and whenever a plan is determined to qualify for a remeasurement during a fiscal year. The remaining components of pension and OPEB plan expense, primarily service cost, interest cost and expected return on assets, are recorded on a monthly basis. The market-related value of assets equals the actual market value as of the date of measurement. During 2024, we made changes to assumptions related to discount rates and expected rates of return on plan assets. We consider available information that we deem relevant when selecting each of these assumptions. In selecting the discount rates for the U.S. plans, we consider expected benefit payments on a plan-by-plan basis. As a result, the Company uses different discount rates for each plan depending on the demographics of participants and the expected timing of benefit payments. For 2024, the discount rates were calculated using the results from a bond matching technique developed by Milliman, which matched the future estimated annual benefit payments of each respective plan against a portfolio of bonds of high quality to determine the discount rate. We believe our selected discount rates are determined using preferred methodology under authoritative accounting guidance and accurately reflect market conditions as of the December 31, 2024 measurement date. In selecting the discount rates for the foreign plans, we look at long-term yields on AA-rated corporate bonds when available. Our actuaries have developed yield curves based on the yields on the constituent bonds in the various indices as well as on other market indicators such as swap rates, particularly at the longer durations. For the Eurozone, we apply the Aon Hewitt yield curve to projected cash flows from the relevant plans to derive the discount rate. For the United Kingdom (“U.K.”), the discount rate is determined by applying the Aon Hewitt yield curve for typical schemes of similar duration to projected cash flows of Albemarle’s U.K. plan. In other countries where there is not a sufficiently deep market of high-quality corporate bonds, we set the discount rate by referencing the yield on government bonds of an appropriate duration. In estimating the expected return on plan assets, we consider past performance and future expectations for the types of investments held by the plan as well as the expected long-term allocation of plan assets to these investments. In projecting the rate of compensation increase, we consider past experience in light of movements in inflation rates. For the purpose of measuring our U.S. pension and OPEB obligations at December 31, 2024 and 2023, we used the Pri-2012 Mortality Tables along with the MP-2021 Mortality Improvement Scale, respectively, published by the SOA.
Stock-based Compensation Expense	Stock-based Compensation Expense The fair value of restricted stock awards, restricted stock unit awards and performance unit awards with a service condition are determined based on the number of shares or units granted and the quoted price of our common stock on the date of grant, and the fair value of stock options is determined using the Black-Scholes valuation model. The fair value of performance unit awards with a service condition and a market condition are estimated on the date of grant using a Monte Carlo simulation model. The fair value of these awards is determined after giving effect to estimated forfeitures. Such value is recognized as expense over the service period, which is generally the vesting period of the equity grant. To the extent restricted stock awards, restricted stock unit awards, performance unit awards and stock options are forfeited prior to vesting in excess of the estimated forfeiture rate, the corresponding previously recognized expense is reversed as an offset to operating expenses.
Income Taxes	Income Taxes We use the liability method for determining our income taxes, under which current and deferred tax liabilities and assets are recorded in accordance with enacted tax laws and rates. Under this method, the amounts of deferred tax liabilities and assets at the end of each period are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not. The Company’s deferred tax assets and liabilities are classified as noncurrent on the balance sheet, along with any related valuation allowance. Tax effects are released from Accumulated other comprehensive loss using either the specific identification approach or the portfolio approach based on the nature of the underlying item. Deferred income taxes are provided for the estimated income tax effect of temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. Deferred tax assets are also provided for operating losses, capital losses and certain tax credit carryovers. A valuation allowance, reducing deferred tax assets, is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The realization of such deferred tax assets is dependent upon the generation of sufficient future taxable income of the appropriate character. Although realization is not assured, we do not establish a valuation allowance when we believe it is more likely than not that a net deferred tax asset will be realized. The Company elected to not consider the estimated impact of potential future Corporate Alternative Minimum Tax liabilities for purposes of assessing valuation allowances on its deferred tax balances. We only recognize a tax benefit after concluding that it is more likely than not that the benefit will be sustained upon audit by the respective taxing authority based solely on the technical merits of the associated tax position. Once the recognition threshold is met, we recognize a tax benefit measured as the largest amount of the tax benefit that, in our judgment, is greater than 50% likely to be realized. Under current accounting guidance for uncertain tax positions, interest and penalties related to income tax liabilities are included in Income tax expense on the consolidated statements of (loss) income. We have designated the undistributed earnings of a portion of our foreign operations as indefinitely reinvested and as a result we do not provide for deferred income taxes on the unremitted earnings of these subsidiaries. Our foreign earnings are computed under U.S. federal tax earnings and profits, or E&P, principles. In general, to the extent our financial reporting book basis over tax basis of a foreign subsidiary exceeds these E&P amounts, deferred taxes have not been provided as they are essentially permanent in duration. The determination of the amount of such unrecognized deferred tax liability is not practicable. We provide for deferred income taxes on our undistributed earnings of foreign operations that are not deemed to be indefinitely invested. We will continue to evaluate our permanent investment assertion taking into consideration all relevant and current tax laws.
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss Accumulated other comprehensive loss comprises principally foreign currency translation adjustments, gains or losses on foreign currency cash flow hedges designated as effective hedging instruments and deferred income taxes related to the aforementioned items.
Foreign Currency Translation	Foreign Currency Translation The assets and liabilities of all foreign subsidiaries were prepared in their respective functional currencies and translated into U.S. Dollars based on the current exchange rate in effect at the balance sheet dates, while income and expenses were translated at average exchange rates for the periods presented. Translation adjustments are reflected as a separate component of equity.
Derivative Financial Instruments	Derivative Financial Instruments We manage our foreign currency exposures by balancing certain assets and liabilities denominated in foreign currencies and through the use of foreign currency forward contracts from time to time, which generally expire within one year. The principal objective of such contracts is to minimize the financial impact of changes in foreign currency exchange rates. While these contracts are subject to fluctuations in value, such fluctuations are generally expected to be offset by changes in the value of the underlying foreign currency exposures being hedged. Gains or losses under foreign currency forward contracts that have been designated as an effective hedging instrument under ASC 815, Derivatives and Hedging will be recorded in Accumulated other comprehensive loss beginning on the date of designation. All other gains and losses on foreign currency forward contracts not designated as an effective hedging instrument are recognized currently in Other income, net, and generally do not have a significant impact on results of operations. We may also enter into interest rate swaps, collars or similar instruments from time to time, with the objective of reducing interest rate volatility relating to our borrowing costs. The counterparties to these contractual agreements 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. We do not utilize financial instruments for trading or other speculative purposes. In the fourth quarter of 2019, we entered into a foreign currency forward contract to hedge the cash flow exposure of non-functional currency purchases during the construction of the Kemerton plant in Australia and designated it as an effective hedging instrument under ASC 815, Derivatives and Hedging . As a result of the actions taken at Kemerton Trains 3 and 4 during 2024, the Company dedesignated the remaining hedged foreign currency forward contracts. The Company recorded a loss in Other income, net of $26.1 million during the year ended December 31, 2024 from the reclassification of the hedged balance from Accumulated other comprehensive loss. The balance of the settled hedged foreign currency forward contracts associated with the construction of Kemerton Trains 1 and 2 assets placed into service will be reclassified to earnings over the life of the related assets. All other foreign currency forward contracts outstanding at December 31, 2024 and 2023 have not been designated as hedging instruments under ASC 815, Derivatives and Hedging .
Recently Issued or Adopted Accounting Pronouncements	Recently Issued or Adopted Accounting Pronouncements In August 2023, the FASB issued guidance which will require a joint venture to recognize and initially measure its assets, including goodwill, and liabilities using a new basis of accounting upon formation. Initial measurement of a joint venture’s total net assets will be equal to the fair value of one hundred percent of the joint venture’s equity. In addition, a joint venture will be permitted to apply the measurement period guidance of ASC 805-10 if the initial accounting for the joint venture formation is incomplete by the end of the reporting period in which the formation occurs. This guidance is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. The Company currently does not expect this guidance to have a significant impact on its consolidated financial statements. In November 2023, the FASB issued guidance to update qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company has adopted this guidance and provided the required disclosures in this Annual Report on Form 10-K. See Note 25, “Segment and Geographic Area Information,” for further details. In December 2023, the FASB issued guidance to require qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. This guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied prospectively; however, retrospective application is also permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures. In November 2024, the FASB issued guidance to require tabular disclosures disaggregating certain types of expenses presented on the income statement within continuing operations, as well as disclosures about selling expenses. This guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted, and the amendments should be applied prospectively; however, retrospective application is also permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.

Significant Differences Between United States Federal Statutory Rate and Effective Income Tax Rate	The reconciliation of the U.S. federal statutory rate to the effective income tax rate is as follows: % of Income Before Income Taxes 2024 2023 2022 Federal statutory rate 21.0 % 21.0 % 21.0 % State taxes, net of federal tax benefit — (2.8) — Change in valuation allowance (a) (26.0) 98.8 (3.9) Impact of foreign earnings, net (b) 3.3 7.7 (0.1) Global intangible low tax inclusion — 4.2 0.3 Foreign-derived intangible income — — (3.0) Section 162(m) limitation (0.3) 4.4 0.3 Subpart F income (0.3) (1.9) 0.2 Stock-based compensation — (3.9) (0.3) Depletion 0.3 (2.4) (0.2) U.S. federal return to provision 0.1 (6.1) (0.4) Revaluation of unrecognized tax benefits/reserve requirements (c) (2.1) 39.1 2.3 Legal accrual — 18.6 — Other items, net (0.9) (2.3) (0.1) Effective income tax rate (4.9) % 174.4 % 16.1 % (a) Due to the Company being in a three-year cumulative loss position in China as of December 31, 2023, and Australia as of December 31, 2024, the year ended December 31, 2024 includes a valuation allowance of $271.0 million on current year losses in certain Chinese entities and the establishment of a valuation of $254.9 million on current year losses in the Company’s Australian entities. In addition, the year ended December 31, 2024 includes benefits of $70.1 million due to the release of a foreign valuation allowance due to changes in expected profitability. (b) Our statutory rate is decreased by our share of the income of JBC, a Free Zones company under the laws of the Hashemite Kingdom of Jordan. The applicable provisions of the Jordanian law, and applicable regulations thereunder, do not have a termination provision and the exemption is indefinite. As a Free Zones company, JBC is not subject to income taxes on the profits of products exported from Jordan, and currently, substantially all of the profits are from exports. This resulted in a rate benefit of 1.2%, 20.1%, and 3.2% for the years ended December 31, 2024, 2023, and 2022, respectively. (c) The year ended December 31, 2024 includes a $37.0 million expense recorded for a current year tax reserve related to an uncertain tax position in Chile.

A third-party estimate of the fair value was prepared using expected future cash flows over the period up to when the asset is likely to be redeemed, applying a discount rate that appropriately captures a market participant's view of the risk associated with the investment. These are considered to be Level 3 inputs. (b) We maintain an EDCP that was adopted in 2001 and subsequently amended. 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 (loss) income) and cash and cash equivalents. As such, these assets and obligations are classified within Level 1. (c) Holdings in equity securities of public companies 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, net, in our consolidated statements of (loss) income. See Note 8, “Investments,” for further details. (d) Primarily consists of private equity securities reported in Investments in the consolidated balance sheets. The changes in fair value are reported in Other income, net in our consolidated statements of (loss) income. (e) Holdings in certain private equity securities 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. (f) The derivative financial instruments are primarily comprised of foreign currency forward contracts. As a result of our global operating and financing activities, we are exposed to market risks from changes in foreign currency exchange rates which may adversely affect our operating results and financial position. When deemed appropriate, we minimize our risks from foreign currency exchange rate fluctuations through the use of foreign currency forward contracts. The foreign currency forward contracts 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 22, “Fair Value of Financial Instruments,” for further details about our foreign currency forward contracts.
