Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 - Significant Accounting Policies Principles of Consolidation: The consolidated financial statements include the accounts and operations of the Company in which a controlling interest is maintained. Investments in affiliated companies where the Company exercises significant influence, but does not control, and the activities of which it is not the primary beneficiary, are accounted for using the equity method. All intercompany accounts and transactions are eliminated upon consolidation. Revenue: A contract exists when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is generally recognized as performance obligations under the terms of a contract with a customer of the Company are satisfied. Of the Company's revenue, approximately 90% is from fixed-price contracts and continues to be recognized as of a point in time when products are shipped from the Company's manufacturing or distribution facilities or at a later point in time when control of the products transfers to the customer. The Company recognizes approximately 10% of revenue over time primarily for certain sales of customer-specific product as it satisfies the performance obligations because of the continuous transfer of control to the customer, supported as follows: • For U.S. government contracts, the customer is allowed to unilaterally terminate the contract for convenience, and is required to pay the Company for costs incurred plus a reasonable margin and can take control of any work in process. • For certain non-U.S. government contracts involving customer-specific products, the customer controls the work in process based on contractual termination clauses or restrictions on the Company's use of the product, and the Company possesses a right to payment for work performed to date plus a reasonable margin. • For certain service contracts, this continuous transfer of control to the customer occurs as the Company's service enhances assets that the customer owns and controls at all times, and the Company is contractually entitled to payment for work performed to date plus a reasonable margin. As a result of control transferring over time, revenue is recognized based on progress toward completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company has elected to use the cost-to-cost input measure of progress for these contracts because it best depicts the transfer of goods or services to the customer based on incurring costs on the contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. The pricing and payment terms for non-U.S. government contracts are based on the Company's standard terms and conditions or the result of specific negotiations with each customer. The Company's standard terms and conditions require payment 30 to 90 days from the invoice date based on geographic region, but the timing of payment for specific negotiated terms may vary. The Company also has both prime and subcontracts in support of the provision of goods and services to the U.S. government. Certain of these contracts are subject to the Federal Acquisition Regulation ("FAR") and are priced based on competitive market prices. Under the payment terms of certain of these U.S. government fixed-price contracts, the customer pays the Company performance-based payments, which are interim payments of up to 90% of the costs incurred to date based on quantifiable measures of performance or on the achievement of specified events or milestones. Because the customer retains a portion of the contract price until completion of such contracts, certain of these U.S. government fixed-price contracts result in revenue recognized in excess of billings, which is presented within "Unbilled receivables" on the Consolidated Balance Sheets. The portion of the payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer. Note 1 - Significant Accounting Policies (continued) Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Sales, value-added, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. As a practical expedient, the Company may exclude an assessment of whether promised goods are performance obligations, if such promised goods are immaterial to the customer contract taken as a whole, and combine these with other performance obligations. The Company has also elected not to adjust the promised amount of consideration for the effects of any significant financing component where the Company expects, at contract inception, that the period between when the Company transfers a promised good to a customer and when the customer pays for that good will be one year or less. Finally, the Company's policy is to exclude performance obligations resulting from contracts with a duration of one year or less from its disclosures related to remaining performance obligations. The amount of consideration to which the Company expects to be entitled in exchange for the goods and services is not generally subject to significant variations. However, the Company does offer certain customers rebates, prompt payment discounts, end-user discounts, the right to return eligible products, and/or other forms of variable consideration. The Company estimates this variable consideration using the expected value amount, which is based on historical experience. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company adjusts the estimate of revenue at the earlier of when the amount of consideration the Company expects to receive changes or when the consideration becomes fixed. The Company recognizes the cost of freight and shipping when control of the products or services has transferred to the customer as an expense in "Cost of products sold" on the Consolidated Statements of Income, because those are costs incurred to fulfill the promise recognized, not a separate performance obligation. To the extent certain freight and shipping fees are charged to customers, the Company recognizes the amounts charged to customers as revenues and the related costs as an expense in "Cost of products sold" when control of the related products or services has transferred to the customer. Contracts are occasionally modified to account for changes in contract specifications, requirements, and pricing. The Company considers contract modifications to exist when the modification either creates new enforceable rights and obligations or changes existing ones. Substantially all of the Company's contract modifications are for goods or services that are distinct from the existing contract. Therefore, the effect of a contract modification on the transaction price and the Company's measure of progress for the performance obligation to which it relates is generally recognized on a prospective basis. Cash Equivalents: The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Restricted Cash: Cash and cash equivalents of $0.4 million were restricted at December 31, 2024 and 2023. Accounts Receivable, Less Allowances: Accounts receivable, less allowances on the Consolidated Balance Sheets include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company maintains an allowance for doubtful accounts, which represents an estimate of the losses expected from the accounts receivable portfolio, to reduce accounts receivable to their net realizable value. The allowance is based upon historical trends in collections and write-offs, management's judgment of the probability of collecting accounts and management's evaluation of business risk. The Company extends credit to customers satisfying predefined credit criteria. The Company believes it has limited concentration of credit risk due to the diversity of its customer base. Unbilled Receivables: Unbilled receivables on the Consolidated Balance Sheets primarily include unbilled amounts typically resulting from sales under long-term contracts when the following conditions exist: (i) cost-to-cost method of revenue recognition is utilized; (ii) the revenue recognized exceeds the amount billed to the customer; and (iii) the right to payment is generally subject to the passage of time as milestones are achieved. The amounts recorded for unbilled receivables do not exceed their net realizable value. Note 1 - Significant Accounting Policies (continued) Inventories: Inventories are valued at the lower of cost or net realizable value, with approximately 59% valued by the first-in, first-out ("FIFO") method and the remaining 41% valued by the last-in, first-out ("LIFO") method. The majority of the Company’s domestic inventories are valued by the LIFO method, while substantially all of the Company’s international inventories are valued by the FIFO method. Investments: Short-term investments are investments with maturities between four months and one year and are valued at amortized cost, which approximates fair value. The Company held short-term investments as of December 31, 2024 and 2023 with a fair value and cost ba sis of $15.9 million an d $31.6 million, respectively, which were included in "Other current assets" on the Consolidated Balance Sheets. Property, Plant and Equipment: Property, plant and equipment, net on the Consolidated Balance Sheets is valued at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. The provision for depreciation is computed by the straight-line method based upon the estimated useful lives of the assets. The useful lives are 10 to 30 years for buildings, three three The impairment of long-lived assets is evaluated when events or changes in circumstances indicate that the carrying amount of the asset or related group of assets may not be recoverable. If the expected future undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized at that time to reduce the asset to the lower of its fair value or its net book value. Leases: The Company determines if any arrangement is a lease at the inception of a contract. For leases where the Company is the lessee, it recognizes lease assets and related lease liabilities at the lease commencement date based on the present value of lease payments over the lease term. Most of the Company’s leases do not provide an implicit interest rate. As a result, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease assets also consist of amounts for favorable or unfavorable lease terms related to acquisitions. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition. A lease asset and lease liability are not recorded for leases with an initial term of 12 months or less, and the lease expense related to these leases is recognized as incurred over the lease term. Goodwill and Other Intangible Assets: Intangible assets subject to amortization are amortized on a straight-line method over their legal or estimated useful lives, with useful lives ranging from one Purchase accounting and business combinations: Assets acquired and the liabilities assumed as part of a business combination are recognized at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. The Company considers inputs to value the assets and liabilities by taking into account competitive trends, market comparisons, independent appraisals, and historical data, among other factors, as supplemented by current and anticipated market conditions. The valuation inputs in these analyses are based on market participant assumptions. The Company may refine these estimates and record adjustments to an asset or liability with the offset to goodwill during the measurement period, which may be up to one year from the acquisition date. Upon the conclusion of the measurement period or final determination of the values of the assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the Company’s Consolidated Statements of Income. Note 1 - Significant Accounting Policies (continued) Product Warranties: The Company provides limited warranties on certain of its products. The Company accrues liabilities for warranties generally based upon specific claims and in certain instances based on historical warranty claim experience in accordance with accounting rules relating to contingent liabilities. When the Company becomes aware of a specific potential warranty claim for which liability is probable and reasonably estimable, a specific charge is recorded and accounted for accordingly. Adjustments are made quarterly to the accruals as claim data and historical experience change. Income Taxes: The Company accounts for income taxes in accordance with ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as net operating loss and tax credit carryforwards. The Company recognizes valuation allowances against deferred tax assets by tax jurisdiction when it is more likely than not those assets will not be realized. Accruals for uncertain tax positions are provided for in accordance with ASC 740-10. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company has elected to account for Global Intangible Low Tax Income as a period cost. Foreign Currency: Assets and liabilities of subsidiaries are translated at the rate of exchange in effect on the balance sheet date; income and expenses are translated at the average rates of exchange prevailing during the reporting period. Translation adjustments for assets and liabilities are reflected as a separate component of accumulated other comprehensive loss (income). Foreign currency gains and losses resulting from transactions are included in the Consolidated Statements of Income. Net of related derivative activity, the Company recognized a foreign currency exchange loss resulting from transactions of $9.3 million for the year ended December 31, 2024 and recognized a loss of $14.8 million and a gain of $15.4 million for the years ended December 31, 2023 and 2022, respectively. Pension and Other Postretirement Benefits: The Company recognizes actuarial gains and losses immediately through net periodic benefit cost upon the annual remeasurement in the fourth quarter, or on an interim basis if specific events trigger a remeasurement. Actuarial gains and losses are excluded from segment results, while all other components of net periodic benefit cost will continue to be included within segment results. Stock-Based Compensation: The Company recognizes stock-based compensation expense over the related vesting period of the awards based on the fair value on the grant date. Stock options are issued with an exercise price equal to the opening market price of Timken common shares on the date of grant. The fair value of stock options is determined using a Black-Scholes option pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate and the expected dividend yield. The fair value of stock-based awards that will settle in Timken common shares, other than stock options, is based on the opening market price of Timken common shares on the grant date. The fair value of stock-based awards that will settle in cash are remeasured at each reporting period until settlement of the awards. The Company recognizes forfeitures on stock-based awards as they occur. Earnings Per Share: Earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the year. Diluted earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding, adjusted for the dilutive impact of potential common shares for share-based compensation awards. Note 1 - Significant Accounting Policies (continued) Derivative Instruments: The Company recognizes all derivatives on the Consolidated Balance Sheets at fair value. Derivatives that are not designated as hedges are adjusted to fair value through earnings. If the derivative is designated and qualifies as a hedge, depending on the nature of the hedge, changes in the fair value of the derivatives are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in accumulated other comprehensive loss (income) until the hedged item is recognized in earnings. The Company’s holdings of forward foreign currency exchange contracts qualify as derivatives pursuant to the criteria established in derivative accounting guidance, and the Company has designated certain of those derivatives as hedges. Use of Estimates: The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Because actual results could differ from these estimates, the Company reviews and updates these estimates and assumptions regularly to reflect recent experience. Recent Accounting Pronouncements: New Accounting Guidance Adopted: In November 2023, the FASB issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280). ASU 2023-07 requires that a public entity disclose: (1) on an annual and interim basis, significant segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM") and included within each reported measure of segment profit or loss; (2) on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition; and (3) the title and position of the CODM and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. The other segment items category is the difference between segment revenue less the segment expenses disclosed and each reported measure of segment profit or loss. For public business entities, the new guidance is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted the new guidance in the fourth quarter of 2024. Refer to Note 4 - Segment Information in the Notes to the Consolidated Financial Statements for additional information. New Accounting Guidance Issued and Not Yet Adopted: In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). ASU 2024-03 requires that a public entity disclose the detailed information about types of expense. Specifically, a public entity would disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation and (d) intangible asset amortization included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)–(d). In addition, a public entity should include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements. A public entity would also disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. For public business entities, the new guidance is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 40). ASU 2023-09 is intended to enhance the transparency and decision to improve the usefulness of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. The amendments require that all entities disclose on an annual basis the amount of income taxes paid disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts exceed a quantitative threshold. For public business entities, the new guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is preparing to adopt the new guidance in 2025.

As a result, the Company utilized third-party valuation specialists to assist in determining the fair value of certain assets. Inputs were generally determined by considering independent appraisals and historical data, supplemented by current and anticipated market conditions. Note 2 - Acquisitions and Divestitures (continued) The 2024 amounts in the table above represent the preliminary purchase price allocation for the CGI acquisition. This purchase price allocation, including the residual amount allocated to goodwill, is based on preliminary information and is subject to change as additional information concerning final asset and liability valuations are obtained. The purchase price allocation for CGI is preliminary as a result of the proximity of the acquisition date to December 31, 2024, and as a result, no elements of the purchase price allocation have been finalized. During the applicable measurement period, the Company will adjust assets and liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values for those assets or liabilities as of that date. The effect of measurement period adjustments to the estimated fair values will be reflected as if the adjustments had been completed on the acquisition date. The following table summarizes the preliminary purchase price allocation at fair value for identifiable intangible assets acquired in 2024 and 2023: 2024 2023 Weighted- Weighted- Trade names (finite life) 6.1 18 years 25.6 17 years Technology and know-how 35.3 16 years 70.5 15 years Customer relationships 59.0 17 years 201.8 14 years Non-competes — 1.0 3 years Capitalized software — 0.6 2 years Total intangible assets $ 100.4 $ 299.5 Divestitures: During the third quarter of 2023, the Company made the decision to sell its TWB business, located in Jiangsu Province, China. The business met the held for sale criteria, and the Company reclassified its assets and liabilities accordingly. As a result of the carrying value of the business exceeding the estimated sales price less costs to sell, the Company recorded an impairment charge of $1.0 million in 2023. On October 16, 2023, the Company completed the divestiture of TWB. TWB had net sales of $22.7 million and $39.3 million in 2023 and 2022, respectively. The results of operations of TWB were reported in the Engineered Bearings segment.

Income Tax Disclosure [Abstract]
Income Taxes	Note 5 - Income Taxes Income before income taxes, based on geographic location of the operations to which such earnings are attributable, is provided below. As the Company has elected to treat certain foreign subsidiaries as branches for U.S. income tax purposes, pretax income attributable to the United States shown below may differ from the pretax income reported in the Company’s annual U.S. federal income tax return. Income before income taxes: 2024 2023 2022 United States $ 175.6 $ 173.8 $ 86.0 Non-United States 318.6 356.7 464.9 Income before income taxes $ 494.2 $ 530.5 $ 550.9 The provision for income taxes consisted of the following: 2024 2023 2022 Current: Federal $ 28.6 $ 10.4 $ 11.2 State and local 9.1 3.8 6.7 Foreign 116.5 119.9 119.6 $ 154.2 $ 134.1 $ 137.5 Deferred: Federal $ (6.6) $ (12.1) $ (7.8) State and local (2.7) (1.5) (0.3) Foreign (26.0) 2.0 4.5 $ (35.3) $ (11.6) $ (3.6) United States and foreign tax provision on income $ 118.9 $ 122.5 $ 133.9 The Company made net income tax payments of $183.5 million, $240.3 million and $120.6 million in 2024, 2023 and 2022, respectively. These income tax payments included $45.2 million and $55.2 million in 2024 and 2023, respectively, that were recorded in other paid-in capital related to sale of shares of Timken India Limited. The following table is the reconciliation between the provision for income taxes and the amount computed by applying the U.S. federal income tax rate of 21% to income before taxes: 2024 2023 2022 Income tax at the U.S. federal statutory rate $ 103.8 $ 111.4 $ 115.7 Adjustments: State and local income taxes, net of federal tax benefit 4.9 5.3 5.3 Tax on foreign remittances and U.S. tax on foreign income 16.8 25.6 19.0 Tax expense related to undistributed earnings of foreign subsidiaries 1.3 15.0 1.0 Foreign losses without current tax benefits 6.1 7.7 3.1 Foreign earnings taxed at different rates including tax holidays 16.6 18.1 19.4 U.S. foreign tax credit (21.1) (55.8) (15.2) Effect of cross-border tax laws (5.2) (10.3) (3.9) Accruals and settlements related to tax audits (6.7) (3.2) (9.5) Other items, net 2.4 8.7 (1.0) Provision for income taxes $ 118.9 $ 122.5 $ 133.9 Effective income tax rate 24.1 % 23.1 % 24.3 % Note 5 - Income Taxes (continued) The Company recognized $55.8 million of tax benefits for U.S. foreign tax credit utilization primarily from acquisition integration structuring for the year ended December 31, 2023. There has been no change in the Company’s assertion about its permanent reinvestment in undistributed foreign earnings. The Company recorded $1.3 million and $15.0 million of income tax expense related to foreign withholding taxes on planned one-time distributions for the years ended December 31, 2024 and 2023, respectively. No additional deferred taxes have been recorded for any other outside basis differences as these amounts continue to be indefinitely reinvested in foreign operations. The amounts of undistributed foreign earnings were $1,834.6 million and $1,608.8 million at December 31, 2024 and December 31, 2023, respectively. It is not practicable to calculate the additional taxes that might be payable on such unremitted earnings due to the variety of circumstances and tax laws applicable at the time of distribution. The Organization for Economic Co-operation and Development ("OECD") has a framework to implement a global minimum corporate tax of 15% applied on a country-by-country basis for companies with global revenues and profits above certain thresholds (referred to as "Pillar 2"), with certain aspects of Pillar 2 effective January 1, 2024 and other aspects effective January 1, 2025. While the United States has not enacted legislation to adopt Pillar 2, and it is uncertain if it will do so in the future, certain countries in which the Company operates have enacted such legislation, and other countries are in the process of doing so. The enactment of Pillar 2 was not material to the Company’s results of operations and financial condition. The effect of temporary differences giving rise to deferred tax assets and liabilities at December 31, 2024 and 2023 was as follows: 2024 2023 Deferred tax assets: Accrued postretirement benefits cost $ 7.9 $ 8.0 Accrued pension cost 39.3 44.1 Other employee benefit accruals 10.7 14.3 Tax loss and credit carryforwards 89.1 84.9 Other, net 75.9 58.3 Valuation allowances (48.7) (39.3) $ 174.2 $ 170.3 Deferred tax liabilities - principally depreciation and amortization (308.2) (312.5) Net deferred tax liabilities $ (134.0) $ (142.2) The Company has U.S. federal and state tax credit and loss carryforwards with tax benefits totaling $23.3 million, portions of which will expire in 2024 and continue until 2043. In addition, the Company has loss carryforwards in various non-U.S. jurisdictions with tax benefits totaling $64.5 million, portions of which will expire in 2025 while others will be carried forward indefinitely. The Company has provided valuation allowances of $47.9 million against certain of these carryforwards and $0.8 million against other deferred tax assets. A majority of the non-U.S. loss carryforwards represent local country net operating losses for branches of the Company or entities treated as branches of the Company under U.S. tax law for which deferred taxes have been recorded. As of December 31, 2024, the Company had $35.8 million of total gross unrecognized tax benefits, $24.4 million of which would favorably impact the Company’s effective income tax rate in any future period if such benefits were recognized. As of December 31, 2024, the Company believes it is reasonably possible that the amount of unrecognized tax positions could decrease by approximately $9 million during the next 12 months. The potential decrease would primarily be driven by settlements with tax authorities and the expiration of various applicable statutes of limitation. As of December 31, 2024, the Company had accrued $11.8 million of interest and penalties related to uncertain tax positions. The Company records interest and penalties related to uncertain tax positions as a component of income tax expense. Note 5 - Income Taxes (continued) As of December 31, 2023, the Company had $34.2 million of total gross unrecognized tax benefits, $24.2 million of which would favorably impact the Company’s effective income tax rate in any future period if such benefits were recognized. As of December 31, 2023, the Company believed it was reasonably possible that the amount of unrecognized tax positions could decrease by approximately $5 million during the next 12 months. The potential decrease would primarily be driven by settlements with tax authorities and the expiration of various applicable statutes of limitation. As of December 31, 2023, the Company had accrued $11.8 million of interest and penalties related to uncertain tax positions. The Company records interest and penalties related to uncertain tax positions as a component of income tax expense. As of December 31, 2022, the Company had $26.0 million of total gross unrecognized tax benefits, $23.3 million of which would favorably impact the Company’s effective income tax rate in any future period if such benefits were recognized. As of December 31, 2022, the Company had accrued $8.8 million of interest and penalties related to uncertain tax positions. The Company records interest and penalties related to uncertain tax positions as a component of income tax expense. The following table reconciles the Company’s total gross unrecognized tax benefits for the years ended December 31, 2024, 2023 and 2022: 2024 2023 2022 Beginning balance, January 1 $ 34.2 $ 26.0 $ 36.1 Tax positions related to the current year: Additions 4.2 7.0 0.6 Tax positions related to prior years: Additions 4.5 9.6 4.0 Reductions (1.6) (4.7) (4.7) Settlements with tax authorities (0.1) (0.4) (1.9) Lapses in statutes of limitation (5.4) (3.3) (8.1) Ending balance, December 31 $ 35.8 $ 34.2 $ 26.0 During 2024 , gross unrecognized tax benefits increased primarily for accruals related to prior year tax matters in multiple jurisdictions related to acquisitions and non-deductible expenses. These increases were partially offset by releases of accruals related to closing agreements and lapses in statute of limitations. During 2023 , gross unrecognized tax benefits increased primarily for accruals related to prior year tax matters in multiple jurisdictions related to acquisitions and non-U.S. non-deductible expenses. These increases were partially offset by releases of accruals related to closing agreements and lapses in statute of limitations. During 2022 , gross unrecognized tax benefits decreased primarily for releases of accruals related to lapses in statute of limitations and reductions related to foreign currency for non-U.S. positions. These decreases were partially offset by accruals for uncertain tax positions related to prior year tax matters in multiple jurisdictions related to acquisitions. As of December 31, 2024, the Company is subject to examination by the IRS for tax years 2019 to the present. The Company also is subject to tax examination in various U.S. state and local tax jurisdictions for tax years 2017 to the present, as well as various foreign tax jurisdictions, including Mexico, China, Poland, France, India, Italy, Romania, Germany, Spain and Slovakia for tax years as early as 2003 to the present. The Company’s unrecognized tax benefits are presented on the Consolidated Balance Sheets as a component of other non-current liabilities, or in certain instances, as a reduction to deferred income taxes.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Note 9 - Goodwill and Other Intangible Assets Goodwill: The Company tests goodwill and indefinite-lived intangible assets for impairment at least annually, performing its annual impairment test as of October 1 st . Furthermore, goodwill and indefinite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Engineered Bearings segment has one reporting unit and the Industrial Motion segment has six reporting units. During the first quarter of 2023, the Company reviewed goodwill for impairment for its reporting units due to the change in segment reporting that went into effect January 1, 2023. The Company utilizes both an income approach and a market approach in testing goodwill for impairment. The Company utilized updated forecasts for the income approach as part of the goodwill impairment review. Based on the earnings and cash flow forecasts for the Belts and Chain reporting unit within the Industrial Motion segment, the Company determined that the reporting unit could not support the carrying value of its goodwill. As a result, the Company recorded a pretax impairment loss of $28.3 million during the first quarter of 2023, which was reported in impairment and restructuring charges on the Consolidated Statement of Income. During the fourth quarter of 2024, the Company recorded an additional goodwill impairment loss of $1.5 million for the Belts and Chain reporting unit, bringing their goodwill balance to zero. This impairment loss is reported in impairment and restructuring charges on the Consolidated Statements of Income. Changes in the carrying value of goodwill were as follows: Year ended December 31, 2024: Engineered Bearings Industrial Motion Total Beginning Balance $ 692.3 $ 677.3 $ 1,369.6 Acquisitions — 61.4 61.4 Measurement period adjustments related to 2023 acquisitions 6.0 0.4 6.4 Impairment loss — (1.5) (1.5) Foreign currency translation adjustments and other changes (6.3) (46.3) (52.6) Ending Balance $ 692.0 $ 691.3 $ 1,383.3 Note 9 - Goodwill and Other Intangible Assets (continued) The acquisition of CGI added goodwill of $61.4 million in 2024. Goodwill arising from this acquisition is attributed to the expected synergies, including future cost savings, and other benefits expected to be generated by combining the companies. The goodwill related to CGI is not deductible for tax purposes. Year ended December 31, 2023: Engineered Bearings Industrial Motion Total Beginning Balance $ 679.8 $ 418.5 $ 1,098.3 Acquisitions 13.2 272.4 285.6 Impairment loss — (28.3) (28.3) Foreign currency translation adjustments and other changes (0.7) 14.7 14.0 Ending Balance $ 692.3 $ 677.3 $ 1,369.6 The acquisitions of Lagersmit, iMECH, Rosa, Des-Case, Nadella and ARB added goodwill of $58.5 million, $12.8 million, $6.5 million, $78.9 million, $128.5 million and $0.4 million, respectively, in 2023. Goodwill arising from these acquisitions is attributed to the expected synergies, including future cost savings, and other benefits expected to be generated by combining the companies. The goodwill related to iMECH and ARB is deductible for tax purposes and will be amortized over 15 years. For the other 2023 acquisitions, goodwill is not deductible for tax purposes. No material goodwill impairment losses were recorded in 2022.

Under the terms of the Accounts Receivable Facility, the Company sells, on an ongoing basis, certain domestic trade receivables to Timken Receivables Corporation, a wholly owned consolidated subsidiary that, in turn, uses the trade receivables to secure borrowings that are funded through a vehicle that issues commercial paper in the short-term market. Borrowings under the Accounts Receivable Facility may be limited to certain borrowing base limitations. These limitations reduced the availability of the Accounts Receivable Facility to $93.9 million at December 31, 2024. As of December 31, 2024, there were no outstanding borrowings under the Accounts Receivable Facility. The cost of this facility, which is the prevailing commercial paper rate plus facility fees, is considered a financing cost and is included in interest expense in the Consolidated Statements of Income. The interest rate was 5.67%, 6.42% and 5.01% at December 31, 2024, 2023 and 2022, respectively. On December 5, 2022, the Company entered into the Credit Agreement, which is comprised of a $750.0 million Senior Credit Facility and $400.0 million 2027 Term Loan, both of which mature on December 5, 2027. The Credit Agreement amended and restated the Company's previous revolving credit agreement that was set to mature on June 25, 2024, and replaced a $350.0 million term loan that was set to mature on September 11, 2023. The interest rates under the Credit Agreement are based on SOFR. At December 31, 2024, the Senior Credit Facility had no outstanding borrowings.

On May 23, 2024, the Company issued the 2034 Notes in the aggregate principal amount of €600 million with an interest rate of 4.13%, maturing on May 23, 2034. Proceeds from the 2034 Notes were used for the redemption of the Company's outstanding 2024 Notes in the aggregate principal amount of $350 million, that were due to mature on September 1, 2024, as well as the repayment of other debt outstanding at the time of issuance. On March 28, 2022, the Company issued the 2032 Notes in the aggregate principal amount of $350.0 million with an interest rate of 4.13%, maturing on April 1, 2032. Proceeds from the 2032 Notes were used for general corporate purposes, which included the repayment of borrowings under the Company's previous senior credit facility and Accounts Receivable Facility at the time of issuance. At December 31, 2024, the Company was in full compliance with all applicable covenants on its outstanding debt. In the ordinary course of business, the Company utilizes standby letters of credit issued by financial institutions to guarantee certain obligations, most of which relate to insurance contracts. At December 31, 2024, outstanding letters of credit totaled $55.7 million, primarily having expiration dates within 12 months. The maturities of long-term debt (including $8.8 million of finance leases) for the years subsequent to December 31, 2024 are as follows: Year 2025 $ 4.3 2026 54.1 2027 513.4 2028 522.3 2029 1.6 Thereafter 977.2 Interest paid was $113.2 million in 2024 , $108.8 million in 2023 and $72.5 million in 2022. This differs from interest expense due to the timing of payments, the amortization of deferred financing fees and interest capitalized of $1.0 million in 2024, $0.2 million in 2023 and $1.0 million in 2022.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Note 14 - Contingencies The Company is responsible for environmental remediation at various manufacturing facilities presently or formerly operated by the Company. In addition, the Company, through one of its subsidiaries, has currently been identified as a potentially responsible party for investigation and remediation under the Comprehensive Environmental Response, Compensation and Liability Act, known as the Superfund, or similar state laws with respect to one site. Claims for investigation and remediation have been asserted against numerous other unrelated entities, which are believed to be financially solvent and are expected to fulfill their proportionate share of the obligation. On December 28, 2004, the United States Environmental Protection Agency (“USEPA”) sent Lovejoy, LLC ("Lovejoy") a Special Notice Letter that identified Lovejoy as a potentially responsible party, together with at least 12 unrelated parties, at the Ellsworth Industrial Park Site, Downers Grove, DuPage County, Illinois (the “Site”). The Company acquired Lovejoy in 2016. Lovejoy’s Downers Grove property is situated within the Ellsworth Industrial Complex. The USEPA and the Illinois Environmental Protection Agency (“IEPA”) allege there have been one or more releases or threatened releases of hazardous substances, including, but not limited to, a release or threatened release on or from Lovejoy's property at the Site. The relief sought by the USEPA and IEPA includes further investigation and potential remediation of the Site and reimbursement of response costs. Lovejoy’s allocated share of past and future costs related to the Site, including for investigation and/or remediation, could be significant. All previously pending property damage and personal injury lawsuits against Lovejoy related to the Site were settled or dismissed prior to our acquisition of Lovejoy. In addition, governmental authorities in the United States and the European Union are increasingly focused on regulating PFAS. PFAS regulations are applicable to portions of the Company's products, and conditions may develop, arise or be discovered that create environmental compliance or remediation liabilities at certain of its facilities. The Company had total environmental accruals of $4.8 million and $4.7 million for various known environmental matters that are probable and reasonably estimable as of December 31, 2024 and 2023, respectively, which includes the Lovejoy matter discussed above. These accruals were recorded based upon the best estimate of costs to be incurred in light of the progress made in determining the magnitude of remediation costs, the timing and extent of remedial actions required by governmental authorities and the amount of the Company’s liability in proportion to other responsible parties. The ultimate resolution of these matters could result in actual costs that exceed amounts accrued. Legal Matter: On June 11, 2024, the Company's subsidiary in India, TIL, received a government order claiming damages (penalties and interest) totaling approximately $12.4 million. The order relates to the closure of TIL’s retirement trust for employees and subsequent transfer of trust assets to the government-administered Employees’ Provident Fund Organization ("EFPO"). The order alleges that the surrender of trust assets did not follow applicable EFPO timing guidelines. TIL believes it fully complied with EFPO requirements and guidelines under the circumstances. TIL is disputing the merits of the order and has filed an appeal with the high court in India having jurisdiction over the matter. Management believes that relief will be provided to TIL once the matter is fully adjudicated; accordingly, no liability has been recorded. While no assurance can be given as to the ultimate outcome of this matter, the Company does not believe that the final resolution will have a material effect on the Company's consolidated financial position or liquidity; however, the effect of any future outcome may be material to the results of operations of any particular period in which costs, if any, are recognized. Note 14 - Contingencies (continued) Product Warranties: In addition to the contingencies above, the Company provides limited warranties on certain of its products. The balances at the end of each respective period represent the best estimates of costs for existing and future claims for products that are still under warranty. The liability primarily relates to accruals for products sold into the automotive and wind energy sectors. Accrual estimates are based on actual claims and expected trends that continue to mature. In addition, the Company continues to evaluate claims raised by certain customers with respect to the performance of bearings sold into the wind energy and automotive sectors. Management believes that the outcome of these claims will not have a material effect on the Company's consolidated financial position; however, the effect of any such change may be material to the results of operations of any particular period in which such change occurs. The following is a rollforward of the consolidated product warranty accrual at December 31, 2024 and 2023: 2024 2023 Beginning balance, January 1 $ 15.2 $ 23.5 Expense 9.4 5.9 Payments (6.6) (14.2) Ending balance $ 18.0 $ 15.2

Defined Benefit Plan Disclosure [Line Items]
Retirement Benefit Plans	Note 17 - Retirement Benefit Plans The Company and its subsidiaries sponsor a number of defined benefit pension plans, which cover eligible employees, including certain employees in foreign countries. These plans generally are noncontributory. Pension benefits earned generally are based on years of service and compensation during active employment. The cash contributions and payments for the Company’s defined benefit pension plans were $24.6 million, $27.1 million and $11.2 million in 2024 , 2023 and 2022, respectively. The following tables summarize the net periodic benefit cost information and the related assumptions used to measure the net periodic benefit cost for the years ended December 31: U.S. Plans International Plans 2024 2023 2022 2024 2023 2022 Components of net periodic Service cost $ 0.7 $ 0.8 $ 6.9 $ 1.9 $ 1.6 $ 1.6 Interest cost 17.1 17.9 17.7 10.2 10.4 5.7 Expected return on plan assets (7.6) (8.5) (18.9) (9.6) (10.4) (9.3) Amortization of prior service cost 0.1 0.2 1.2 0.2 0.2 0.1 Recognition of net actuarial (1.3) 9.2 22.6 0.6 12.4 (6.6) Curtailment gain — — — (0.1) — — Net periodic benefit cost (credit) $ 9.0 $ 19.6 $ 29.5 $ 3.2 $ 14.2 $ (8.5) Assumptions 2024 2023 2022 U.S. Plans: Discount rate 5.37% to 5.53% 5.62% to 5.74% 3.03% to 4.95% Future compensation assumption 3.25% 2.50% to 3.50% 2.50% to 3.50% Expected long-term return on plan assets 2.09% to 4.67% 4.31% to 4.91% 4.35% to 5.65% International Plans: Discount rate 3.15% to 11.70% 3.70% to 10.70% 1.00% to 9.50% Future compensation assumption 3.00% to 8.00% 2.80% to 8.00% 2.10% to 8.00% Expected long-term return on plan assets 2.50% to 8.90% 2.50% to 8.90% 2.00% to 8.90% The following table summarizes assumptions used to measure the benefit obligation for the defined benefit pension plans at December 31: Assumptions 2024 2023 U.S. Plans: Discount rate 5.78% to 5.84% 5.37% to 5.53% Future compensation assumption 3.00% 3.25 % International Plans: Discount rate 3.35% to 11.40% 3.15% to 11.70% Future compensation assumption 2.62% to 8.00% 3.00% to 8.00% Note 17 - Retirement Benefit Plans (continued) The Company recognized actuarial gains of $0.7 million during 2024 primarily due to the impact of a net increase in the discount rate used to measure its defined benefit pension obligations of $28.7 million, partially offset by lower than expected returns on plan assets of $26.8 million and experience losses of $1.2 million. The impact of the net increase in the discount rate used to measure the Company's defined benefit pension obligations was primarily driven by a 95 basis point increase in the discount rate used to measure its U.K. plan obligations, which increased from 4.48% in 2023 to 5.43% in 2024, and a 43 basis point increase in the weighted-average discount rate used to measure its U.S. plan obligations, which increased from 5.40% in 2023 to 5.83% in 2024. The Company recognized actuarial losses of $21.6 million during 2023 primarily due to the impact of a net reduction in the discount rate used to measure its defined benefit pension obligations of $17.6 million and the impact of experience losses of $10.3 million, partially offset by changes in mortality of $6.0 million primarily related to the U.K. plan obligations and other actuarial gains of $0.3 million. The impact of the net reduction in the discount rate used to measure the Company's defined benefit pension obligations was primarily driven by a 24 basis point reduction in the weighted-average discount rate used to measure its U.S. plan obligations, which decreased from 5.64% in 2022 to 5.40% in 2023, and a 33 basis point decrease in the discount rate used to measure its U.K. plan obligations, which decreased from 4.81% in 2022 to 4.48% in 2023. Returns on plan assets had no impact on actuarial losses for 2023. The Company recognized actuarial losses of $16.0 million during 2022 primarily due to the impact of lower than expected returns on plan assets of $220.6 million, the impact of experience losses of $33.0 million, the impact of inflation of $5.4 million and other actuarial losses of $0.2 million, partially offset by the favorable impact of a net increase in the discount rate used to measure its defined benefit pension obligations of $243.2 million. The impact of the net increase in the discount rate used to measure the Company's defined benefit pension obligations was primarily driven by a 257 basis point increase in the weighted-average discount rate used to measure its U.S. plan obligations, which increased from 3.07% in 2021 to 5.64% in 2022, and a 301 basis point increase in the discount rate used to measure its U.K. plan obligations, which increased from 1.80% in 2021 to 4.81% in 2022. For expense purposes in 2024, the Company applied a weighted-average discount rate of 5.40% to its U.S. defined benefit pension plans. For expense purposes in 2025, the Company will apply a weighted-average discount rate of 5.83% to its U.S. defined benefit pension plans. For expense purposes in 2024, the Company applied a weighted-average expected rate of return of 3.94% for the Company’s U.S. pension plan assets. For expense purposes in 2025, the Company will apply a weighted-average expected rate of return on plan assets of 4.30%. Note 17 - Retirement Benefit Plans (continued) The following tables set forth the change in the benefit obligation and plan assets, funded status and amounts recognized on the Consolidated Balance Sheets for defined benefit pension plans as of December 31, 2024 and 2023: U.S. Plans International Plans 2024 2023 2024 2023 Change in benefit obligation: Benefit obligation at beginning of year $ 333.2 $ 335.3 $ 242.3 $ 218.1 Service cost 0.7 0.8 1.9 1.6 Interest cost 17.1 17.9 10.2 10.4 Plan amendments — — 0.3 — Actuarial (gains) losses (12.6) 10.8 (14.9) 10.8 International plan exchange rate change — — (6.9) 10.4 Curtailments — — (0.1) — Benefits paid (21.0) (31.6) (15.0) (14.7) Acquisitions — — — 3.9 Other — — 0.4 1.8 Benefit obligation at end of year $ 317.4 $ 333.2 $ 218.2 $ 242.3 Change in plan assets: Fair value of plan assets at beginning of year $ 199.2 $ 201.6 $ 196.8 $ 185.5 Actual return on plan assets (3.7) 10.1 (5.9) 8.8 Company contributions / payments 20.5 19.1 4.1 8.0 International plan exchange rate change — — (4.1) 9.2 Benefits paid (21.0) (31.6) (15.0) (14.7) Fair value of plan assets at end of year 195.0 199.2 175.9 196.8 Funded status at end of year $ (122.4) $ (134.0) $ (42.3) $ (45.5) Amounts recognized on the Consolidated Balance Sheets: Current liabilities $ (4.9) $ (4.8) $ (2.1) $ (2.4) Non-current liabilities (117.5) (129.2) (40.2) (43.1) $ (122.4) $ (134.0) $ (42.3) $ (45.5) Amounts recognized in accumulated other comprehensive loss: Net prior service cost $ — $ 0.1 $ 3.6 $ 3.6 Accumulated other comprehensive loss $ — $ 0.1 $ 3.6 $ 3.6 Changes in prior service cost recognized in accumulated other Accumulated other comprehensive loss at beginning of year $ 0.1 $ 0.3 $ 3.6 $ 3.6 Prior service cost — — 0.3 — Recognized prior service cost (0.1) (0.2) (0.2) (0.2) Foreign currency impact — — (0.1) 0.2 Total recognized in accumulated other comprehensive $ — $ 0.1 $ 3.6 $ 3.6 The presentation in the above tables for amounts recognized in accumulated other comprehensive loss on the Consolidated Balance Sheets is before the effect of income taxes. Note 17 - Retirement Benefit Plans (continued) No defined benefit pension plans were overfunded as of December 31, 2024 and 2023. The current portion of accrued pension benefits, which was included in salaries, wages and benefits on the Consolidated Balance Sheets, was $7.0 million and $7.2 million at December 31, 2024 and 2023, respectively. In 2024, the current portion of accrued pension benefits relates to unfunded plans and represents the actuarial present value of expected payments related to the plans to be made over the next 12 months. The four largest defined benefit pension plans, covering certain employees in the United States and U.K., represent 83% of the Company's projected benefit obligation at December 31, 2024 and 2023. These defined benefit pension plans are closed to new entrants and benefits have been frozen for three of these plans. The projected benefit obligation at December 31, 2024 exceeded the market value of plan assets for most of the Company's pension plans. For these plans, the projected benefit obligation was $534.9 million, the accumulated benefit obligation was $527.6 million and the fair value of plan assets was $370.3 million at December 31, 2024. The accumulated benefit obligation at December 31, 2024 exceeded the market value of plan assets for most of the Company’s pension plans. For these plans, the projected benefit obligation was $526.3 million, the accumulated benefit obligation was $521.4 million and the fair value of plan assets was $361.9 million at December 31, 2024. The total accumulated benefit obligation for all plans was $528.0 million and $567.0 million at December 31, 2024 and 2023, respectively. Investment performance decreased the value of the Company’s pension assets by 1.4% in 2024 largely due to increases in bond rates. As of December 31, 2024 , 2023 and 2022, the Company’s defined benefit pension plans did not directly hold any of the Company’s common shares. Plan Assets: The Company’s target allocation for pension plan assets, as well as the actual pension plan asset allocations as of December 31, 2024 and 2023, was as follows: Current Target Percentage of Pension Plan Asset Category 2024 2023 Equity securities 10% to 14% 13% 13% Fixed income securities 78% to 90% 83% 84% Other investments 2% to 6% 4% 3% Total 100% 100% The Company recognizes its overall responsibility to ensure that the assets of its various defined benefit pension plans are managed effectively and prudently and in compliance with its policy guidelines and all applicable laws. Preservation of capital is important; however, the Company also recognizes that appropriate levels of risk are necessary to allow its investment managers to achieve satisfactory long-term results consistent with the objectives and the fiduciary character of the pension funds. Asset allocations are established in a manner consistent with projected plan liabilities, benefit payments and expected rates of return for various asset classes, and are reviewed regularly by management. The expected rate of return for the investment portfolio is based on expected rates of return for various asset classes, as well as historical asset class and fund performance. Note 17 - Retirement Benefit Plans (continued) 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 FASB provides accounting rules that classify the inputs used to measure fair value 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.

Cash and cash equivalents are valued at redemption value. Government and agency securities are valued at the closing price reported in the active market in which the individual securities are traded. Certain corporate bonds are valued at the closing price reported in the active market in which the bond is traded. Equity securities (both common and preferred stock) are valued at the closing price reported in the active market in which the individual security is traded. Common collective funds are valued based on a net asset value per share. Mutual funds classified as Level 1 assets include investments in fixed income and international equities. These investments are comprised of securities listed on exchange, market, or automated quotation systems, for which active, quoted prices are available. Mutual funds are valued based on a net asset value per share for shares held at year end, as determined by the closing price reported on the active market on which the individual securities are traded, or a pricing vendor or the fund family if an active market is not available. Asset-backed securities are valued based on quoted prices for similar assets in active markets. When such prices are unavailable, the plan trustee determines a valuation from the market maker dealing in the particular security. Note 17 - Retirement Benefit Plans (continued) Limited partnerships include investments in funds that invest primarily in private equity, venture capital and distressed debt. Limited partnerships are valued based on the ownership interest in the net asset value of the investment, which is used as a practical expedient to fair value, per the underlying investment fund, which is based upon the general partner's own assumptions about the assumptions a market participant would use in pricing the assets and liabilities of the partnership. Real estate investments include funds that invest in companies that primarily invest in commercial and residential properties, commercial mortgage-backed securities, debt and equity securities of real estate operating companies, and real estate investment trusts. Other real estate investments are valued based on the ownership interest in the net asset value of the investment, which is used as a practical expedient to fair value per the underlying investment fund, which is based on appraised values and current transaction prices. Other liability-driven investments mainly include investments in index-linked open-end swap funds. These funds invest in cash held deposits that reflect the index-linked deferred annuity with payment terms of specific years linked to UK inflation measures. The underlying assets in this investment are valued daily. Cash Flows: Employer Contributions to Defined Benefit Plans 2023 $ 27.1 2024 24.6 2025 (estimated) 37.6 Estimated future benefit payments, including estimated lump sum distributions, are expected to be as follows: Benefit Payments 2025 $ 56.4 2026 48.5 2027 44.2 2028 42.6 2029 41.7 2030-2034 211.3 U.K. Pension Plan In January 2025, the Company entered into an insurance buy-in contract for its pension obligation for its U.K. defined benefit pension plan which was funded from existing pension plan assets without any adjustment to the benefit obligation. In addition, the Company contributed £6 million towards this insurance buy-in contract. The insurance buy-in contract will be classified as “Annuity Contracts” since the insurance buy-in contract is similar to an annuity contract. The insurance buy-in contract matches cash flows with future benefit payments for participants as of the contract date with the obligation remaining with the plan. Employee Savings Plans:

Other Postretirement Benefit Plans	Note 18 - Other Postretirement Benefit Plans The Company and its subsidiaries sponsor several postretirement plans that provide health care and life insurance benefits for eligible retirees and dependents. Depending on retirement date and employee classification, certain health care plans contain contribution and cost-sharing features such as deductibles, coinsurance and limitations on employer-provided subsidies. The remaining health care and life insurance plans are noncontributory. The following tables summarize the net periodic benefit cost information and the related assumptions used to measure the net periodic benefit cost for the years ended December 31: 2024 2023 2022 Components of net periodic credit: Service cost $ 0.1 $ 0.1 $ 0.2 Interest cost 1.7 1.9 1.4 Amortization of prior service credit (8.2) (8.3) (10.1) Recognition of net actuarial gains (0.5) (1.0) (13.1) Net periodic credit $ (6.9) $ (7.3) $ (21.6) Assumptions: 2024 2023 2022 Discount rate 5.55 % 5.75 % 2.99 % The following table summarizes assumptions used to measure the benefit obligation for the other postretirement benefit plans at December 31: Assumptions: 2024 2023 Discount rate 5.83 % 5.55 % The Company recognized actuarial gains of $0.5 million during 2024 primarily due to lower than expected benefit payments of $2.0 million, the impact of experience gains of $1.2 million and $0.6 million due to the impact of a 28 basis point increase in the discount rate used to measure the Company's defined benefit postretirement obligations. The discount rate increased from 5.55% in 2023 to 5.83% in 2024. These actuarial gains were partially offset by actuarial losses of $3.1 million due to the impact of an increase in the rate of Medicare Advantage plans and $0.2 million due to changes in other actuarial assumptions. The Company recognized actuarial gains of $1.0 million during 2023 primarily due to lower than expected benefit payments of $1.4 million and $0.1 million due to changes in other actuarial assumptions. These actuarial gains were partially offset by a $0.5 million loss due to the impact of a 20 basis point decrease in the discount rate used to measure the Company's defined benefit postretirement obligations, which decreased from 5.75% in 2022 to 5.55% in 2023. The Company recognized actuarial gains of $13.1 million during 2022 primarily due to the impact of a 276 basis point increase in the discount rate used to measure the Company's defined benefit postretirement obligations, which increased from 2.99% in 2021 to 5.75% in 2022. The increase in the discount rate resulted in a $8.4 million gain. In addition to the gain from the discount rate increases, the Company recognized actuarial gains of $3.0 million due to the impact of a reduction in the rate of Medicare Advantage plans and $1.9 million due to lower than expected benefit payments. These actuarial gains were offset by $0.2 million of changes in other actuarial assumptions . Note 18 - Other Postretirement Benefit Plans (continued) The discount rate assumption is based on current rates of high-quality long-term corporate bonds over the same period that benefit payments will be required to be made. For expense purposes in 2024, the Company applied a discount rate of 5.55% to its other postretirement benefit plans. For expense purposes in 2025, the Company will apply a discount rate of 5.83% to its other postretirement benefit plans. The following tables set forth the change in the benefit obligation and amounts recognized on the Consolidated Balance Sheets for other postretirement benefit plans as of December 31, 2024 and 2023: 2024 2023 Change in benefit obligation: Benefit obligation at beginning of year $ 33.7 $ 35.5 Service cost 0.1 0.1 Interest cost 1.7 1.9 Actuarial gains (0.5) (1.0) International plan exchange rate change — (0.1) Benefits paid (1.6) (2.7) Benefit obligation at end of year $ 33.4 $ 33.7 Funded status at end of year $ (33.4) $ (33.7) Amounts recognized on the Consolidated Balance Sheets: Current liabilities $ (3.6) $ (3.5) Non-current liabilities (29.8) (30.2) $ (33.4) $ (33.7) Amounts recognized in accumulated other comprehensive loss: Net prior service credit $ (55.4) $ (63.6) Accumulated other comprehensive loss $ (55.4) $ (63.6) Changes to prior service credit recognized in accumulated other Accumulated other comprehensive loss at beginning of year $ (63.6) $ (71.9) Recognized prior service credit 8.2 8.3 Total recognized in accumulated other comprehensive loss at December 31 $ (55.4) $ (63.6) The presentation in the above tables for amounts recognized in accumulated other comprehensive loss on the Consolidated Balance Sheets is before the effect of income taxes. The current portion of accrued postretirement benefits, which was included in salaries, wages and benefits on the Consolidated Balance Sheets, was $3.6 million and $3.5 million at December 31, 2024 and 2023, respectively. In 2024, the current portion of accrued postretirement benefits related to unfunded plans and represented the actuarial present value of expected payments related to the plans to be made over the next 12 months. Note 18 - Other Postretirement Benefit Plans (continued) For measurement purposes, the Company assumed a weighted-average annual rate of increase in the per capita cost (health care cost trend rate) of 7.00% for 2025, declining gradually to 5.0% in 2033 and thereafter for medical and prescription drug benefits. For Medicare Advantage benefits, actual contract rates have been set for 2025 through 2026, and are assumed to increase by $10 per year for 2027 through 2029 and then 6.0% for 2029, declining gradually to 5.0% in 2033 and thereafter. Cash Flows: Estimated future benefit payments to be funded by the Company are expected to be as follows: Future Benefit Payments 2025 $ 3.7 2026 3.7 2027 3.6 2028 3.5 2029 3.4 2030-2034 14.0

Short-term investments are investments with maturities between 91 days and one year, and generally are valued at amortized cost, which approximates fair value. A portion of the cash and cash equivalents and short-term investments are valued based on net asset value. The Company uses publicly available market interest rates to measure the fair value of its interest rate swap contracts. The Company uses publicly available foreign currency forward and spot rates to measure the fair value of its foreign currency forward contracts. In addition, the Company remeasures certain assets to fair value, using Level 3 measurements, as a result of the occurrence of triggering events such as purchase accounting for acquisitions or goodwill impairment. No material assets were measured at fair value on a nonrecurring basis during the years ended December 31, 2024 and 2023. Note 21 - Fair Value (continued) Financial Instruments: The Company’s financial instruments consist primarily of cash and cash equivalents, short-term investments, net accounts receivable, trade accounts payable, short-term borrowings and long-term debt. Due to their short-term nature, the carrying value of cash and cash equivalents, short-term investments, accounts receivable, trade accounts payable, and short-term borrowings are a reasonable estimate of their fair value. Due to the nature of fair value calculations for variable-rate debt, the carrying value of the Company's long-term variable-rate debt is a reasonable estimate of its fair value. The fair value of the Company’s long-term fixed-rate debt, based on quoted market prices, was $1,659.2 million and $1,387.7 million at December 31, 2024 and 2023, respectively. The carrying value of this debt was $1,675.6 million and $1,424.3 million at December 31, 2024 and 2023, respectively. The fair value of long-term fixed-rate debt was measured using Level 2 inputs. The Company does not believe it has significant concentrations of risk associated with the counterparts to its financial instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 22 - Derivative Instruments The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are foreign currency exchange rate risk and interest rate risk. Forward contracts on various foreign currencies are entered into in order to manage the foreign currency exchange rate risk associated with certain of the Company's commitments denominated in foreign currencies. From time to time, interest rate swaps are used to manage interest rate risk associated with the Company’s fixed, and floating-rate borrowings. The Company designates certain foreign currency forward contracts as cash flow hedges of forecasted revenues and certain interest rate hedges as cash flow hedges of fixed-rate borrowings. On May 23, 2024, the Company designated its 2034 Notes, in the aggregate principal amount of €600.0 million, as a hedge against its net investment in one of its European subsidiaries. The objective of the hedge transaction is to protect the net investment in the foreign operations against changes in the exchange rate between the U.S. dollar and the Euro. The net impact for the year ended December 31, 2024 was a gain of $27.7 million recorded to accumulated comprehensive (loss) income. On September 15, 2020, the Company designated €54.5 million of its €150.0 million fixed-rate senior unsecured notes, maturing on September 7, 2027 (the "2027 Notes") as a hedge against its net investment in one of its European subsidiaries. The objective of the hedge transaction is to protect the net investment in the foreign operations against changes in the exchange rate between the U.S. dollar and the Euro. The net impact for the year ended December 31, 2024 was to record a gain of $3.7 million to accumulated comprehensive loss (income). The Company does not purchase or hold any derivative financial instruments for trading purposes. As of December 31, 2024 and 2023, the Compan y had $471.6 million and $591.8 million, respectively, of outstanding foreign currency forward contracts at notional value. Refer to Note 21 - Fair Value for the fair value disclosure of derivative financial instruments. Foreign currency forward contracts classified as assets are included in other current assets, and foreign currency forward contracts classified as liabilities are included in other current liabilities on the Consolidated Balance Sheets. Cash Flow Hedging Strategy: For certain derivative instruments that are designated and qualify as cash flow hedges ( i.e ., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. To protect against a reduction in the value of forecasted foreign currency cash flows resulting from export sales, the Company has instituted a foreign currency cash flow hedging program. The Company hedges portions of its forecasted cash flows denominated in foreign currencies with forward contracts. When the dollar strengthens significantly against foreign currencies, the decline in the present value of future foreign currency revenue is offset by gains in the fair value of the forward contracts designated as hedges. Conversely, when the dollar weakens, the increase in the present value of future foreign currency cash flows is offset by losses in the fair value of the forward contracts. As of December 31, 2024 and 2023, the Company had $63.0 million and $73.8 million, respectively, of outstanding foreign currency forward contracts at notional value that were classified as cash flow hedges. The maximum length of time over which the Company hedges it exposure to the variability in future cash flows for forecast transactions is generally eighteen months or less. Note 22 - Derivative Instruments (continued) Derivative Instruments not designated as Hedging Instruments: For derivative instruments that are not designated as hedging instruments, the instruments are typically forward contracts. In general, the practice is to reduce volatility by selectively hedging transaction exposures including intercompany loans, accounts payable and accounts receivable. Intercompany loans between entities with different functional currencies typically are hedged with a forward contract at the inception of loan with a maturity date at the maturity of the loan. The revaluation of these contracts, as well as the revaluation of the underlying balance sheet items, is recorded directly to the income statement so the adjustment generally offsets the revaluation of the underlying balance sheet items to protect cash payments and reduce income statement volatility. As of December 31, 2024 and 2023 , the Company had $408.6 million and $518.0 million, respectively, of outstanding foreign currency forward contracts at notional value that were not designated as hedging instruments. The following table presents the impact of derivative instruments not designated as hedging instruments for the years ended December 31, 2024, 2023 and 2022, and the related location within the Consolidated Statements of Income.

Government Assistance [Abstract]
Government Assistance	Note 24 - Government Assistance From time to time, the Company receives government assistance in the form of grants and other incentives from various governments to support capital projects and other business development. The amounts received are typically based on the amount of qualifying capital expenditures or business development costs in the countries providing the government assistance. The Company typically has to meet certain requirements, such as adding or maintaining a specified number of qualifying positions, to retain the government assistance or the funds can be clawed back by the government. Once the Company determines that it will meet the requirements of the government assistance, the funds are recognized over the life of the related assets or as the costs are incurred. For amounts that are expected to be paid back, the Company recognizes applicable interest expense. As of December 31, 2024 and December 31, 2023, the Company has recorded $1.5 million and $1.6 million, respectively, of government assistance in other current liabilities other non-current liabilities cost of products sold SG&A interest expense In December 2023, the Company reached a definitized technology investment agreement with the United States Government for the purposes of enhancing and expanding the industrial base for high performance, precision ball bearings. Title to assets purchased under this agreement vest with the Government throughout the agreement. The Government may elect to transfer all, or some, of the assets purchased to the Company at the end of the agreement, provided the Company's performance is satisfactory and in compliance with the terms of the agreement. As of December 31, 2024, the company is accounting for $7.2 million of awards received as other non-current liabilities cost of products sold In 2022, the Company acquired Spinea, s.r.o. ("Spinea"). Prior to the acquisition, Spinea received incentives totaling $18.0 million from the Slovakian government to invest in a new production facility and related machinery and equipment. As a result, Spinea was required to create 450 new jobs. If Spinea is unable to meet these commitments, all or a portion of the incentive could be recaptured with interest by October 2027. The Company is currently accounting for a potential shortfall of $16.6 million, including interest. The remaining amount is being amortized over the period the costs are being incurred. Cumulatively as of December 31, 2024, the Company recorded amortization expense of $3.3 million as a reduction to cost of products sold interest expense In 2017 and 2018, the Company received grants from the Romanian Government for the reimbursement of capital investments for its new production facility, totaling $16.5 million. While the original grants were based on capital investments, the Company needs to pay various taxes, including corporate income tax, payroll taxes and building tax, totaling $16.6 million between 2019 and 2024. If the total tax obligation is not met, any shortfall could result in a recapture of the grant with interest as early as December 2024. The Company is currently accounting for a potential shortfall of $8.4 million, including interest. The incentive is being amortized over the useful life of the assets. Cumulatively as of December 31, 2024, the Company recorded amortization expense of $2.0 million as a reduction to cost of products sold interest expense The Company may have received other government assistance that is not described above; however, the total amount of the government assistance is immaterial to the Company’s Consolidated Financial Statements.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation:
Revenue	Revenue: A contract exists when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is generally recognized as performance obligations under the terms of a contract with a customer of the Company are satisfied. Of the Company's revenue, approximately 90% is from fixed-price contracts and continues to be recognized as of a point in time when products are shipped from the Company's manufacturing or distribution facilities or at a later point in time when control of the products transfers to the customer. The Company recognizes approximately 10% of revenue over time primarily for certain sales of customer-specific product as it satisfies the performance obligations because of the continuous transfer of control to the customer, supported as follows: • For U.S. government contracts, the customer is allowed to unilaterally terminate the contract for convenience, and is required to pay the Company for costs incurred plus a reasonable margin and can take control of any work in process. • For certain non-U.S. government contracts involving customer-specific products, the customer controls the work in process based on contractual termination clauses or restrictions on the Company's use of the product, and the Company possesses a right to payment for work performed to date plus a reasonable margin. • For certain service contracts, this continuous transfer of control to the customer occurs as the Company's service enhances assets that the customer owns and controls at all times, and the Company is contractually entitled to payment for work performed to date plus a reasonable margin. As a result of control transferring over time, revenue is recognized based on progress toward completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company has elected to use the cost-to-cost input measure of progress for these contracts because it best depicts the transfer of goods or services to the customer based on incurring costs on the contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. The pricing and payment terms for non-U.S. government contracts are based on the Company's standard terms and conditions or the result of specific negotiations with each customer. The Company's standard terms and conditions require payment 30 to 90 days from the invoice date based on geographic region, but the timing of payment for specific negotiated terms may vary. The Company also has both prime and subcontracts in support of the provision of goods and services to the U.S. government. Certain of these contracts are subject to the Federal Acquisition Regulation ("FAR") and are priced based on competitive market prices. Under the payment terms of certain of these U.S. government fixed-price contracts, the customer pays the Company performance-based payments, which are interim payments of up to 90% of the costs incurred to date based on quantifiable measures of performance or on the achievement of specified events or milestones. Because the customer retains a portion of the contract price until completion of such contracts, certain of these U.S. government fixed-price contracts result in revenue recognized in excess of billings, which is presented within "Unbilled receivables" on the Consolidated Balance Sheets. The portion of the payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer. Note 1 - Significant Accounting Policies (continued) Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Sales, value-added, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. As a practical expedient, the Company may exclude an assessment of whether promised goods are performance obligations, if such promised goods are immaterial to the customer contract taken as a whole, and combine these with other performance obligations. The Company has also elected not to adjust the promised amount of consideration for the effects of any significant financing component where the Company expects, at contract inception, that the period between when the Company transfers a promised good to a customer and when the customer pays for that good will be one year or less. Finally, the Company's policy is to exclude performance obligations resulting from contracts with a duration of one year or less from its disclosures related to remaining performance obligations. The amount of consideration to which the Company expects to be entitled in exchange for the goods and services is not generally subject to significant variations. However, the Company does offer certain customers rebates, prompt payment discounts, end-user discounts, the right to return eligible products, and/or other forms of variable consideration. The Company estimates this variable consideration using the expected value amount, which is based on historical experience. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company adjusts the estimate of revenue at the earlier of when the amount of consideration the Company expects to receive changes or when the consideration becomes fixed. The Company recognizes the cost of freight and shipping when control of the products or services has transferred to the customer as an expense in "Cost of products sold" on the Consolidated Statements of Income, because those are costs incurred to fulfill the promise recognized, not a separate performance obligation. To the extent certain freight and shipping fees are charged to customers, the Company recognizes the amounts charged to customers as revenues and the related costs as an expense in "Cost of products sold" when control of the related products or services has transferred to the customer. Contracts are occasionally modified to account for changes in contract specifications, requirements, and pricing. The Company considers contract modifications to exist when the modification either creates new enforceable rights and obligations or changes existing ones. Substantially all of the Company's contract modifications are for goods or services that are distinct from the existing contract. Therefore, the effect of a contract modification on the transaction price and the Company's measure of progress for the performance obligation to which it relates is generally recognized on a prospective basis.
Cash Equivalents	Cash Equivalents: The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Restricted Cash	Restricted Cash: Cash and cash equivalents of $0.4 million were restricted at December 31, 2024 and 2023.
Accounts Receivable, Less Allowance	Accounts Receivable, Less Allowances: Accounts receivable, less allowances on the Consolidated Balance Sheets include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company maintains an allowance for doubtful accounts, which represents an estimate of the losses expected from the accounts receivable portfolio, to reduce accounts receivable to their net realizable value. The allowance is based upon historical trends in collections and write-offs, management's judgment of the probability of collecting accounts and management's evaluation of business risk. The Company extends credit to customers satisfying predefined credit criteria. The Company believes it has limited concentration of credit risk due to the diversity of its customer base.
Unbilled Receivables	Unbilled Receivables: Unbilled receivables on the Consolidated Balance Sheets primarily include unbilled amounts typically resulting from sales under long-term contracts when the following conditions exist: (i) cost-to-cost method of revenue recognition is utilized; (ii) the revenue recognized exceeds the amount billed to the customer; and (iii) the right to payment is generally subject to the passage of time as milestones are achieved. The amounts recorded for unbilled receivables do not exceed their net realizable value.
Inventories	Inventories: Inventories are valued at the lower of cost or net realizable value, with approximately 59% valued by the first-in, first-out ("FIFO") method and the remaining 41% valued by the last-in, first-out ("LIFO") method. The majority of the Company’s domestic inventories are valued by the LIFO method, while substantially all of the Company’s international inventories are valued by the FIFO method.
Investments	Investments: Short-term investments are investments with maturities between four months and one year and are valued at amortized cost, which approximates fair value. The Company held short-term investments as of December 31, 2024 and 2023 with a fair value and cost ba sis of $15.9 million an d $31.6 million, respectively, which were included in "Other current assets" on the Consolidated Balance Sheets.
Property, Plant and Equipment	Property, Plant and Equipment: Property, plant and equipment, net on the Consolidated Balance Sheets is valued at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. The provision for depreciation is computed by the straight-line method based upon the estimated useful lives of the assets. The useful lives are 10 to 30 years for buildings, three three The impairment of long-lived assets is evaluated when events or changes in circumstances indicate that the carrying amount of the asset or related group of assets may not be recoverable. If the expected future undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized at that time to reduce the asset to the lower of its fair value or its net book value.
Leases	Leases: The Company determines if any arrangement is a lease at the inception of a contract. For leases where the Company is the lessee, it recognizes lease assets and related lease liabilities at the lease commencement date based on the present value of lease payments over the lease term. Most of the Company’s leases do not provide an implicit interest rate. As a result, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease assets also consist of amounts for favorable or unfavorable lease terms related to acquisitions. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition. A lease asset and lease liability are not recorded for leases with an initial term of 12 months or less, and the lease expense related to these leases is recognized as incurred over the lease term.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: one
Purchase accounting and business combinations	Purchase accounting and business combinations:
Product Warranties	Product Warranties: The Company provides limited warranties on certain of its products. The Company accrues liabilities for warranties generally based upon specific claims and in certain instances based on historical warranty claim experience in accordance with accounting rules relating to contingent liabilities. When the Company becomes aware of a specific potential warranty claim for which liability is probable and reasonably estimable, a specific charge is recorded and accounted for accordingly. Adjustments are made quarterly to the accruals as claim data and historical experience change.
Income Taxes	Income Taxes: The Company accounts for income taxes in accordance with ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as net operating loss and tax credit carryforwards. The Company recognizes valuation allowances against deferred tax assets by tax jurisdiction when it is more likely than not those assets will not be realized. Accruals for uncertain tax positions are provided for in accordance with ASC 740-10. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company has elected to account for Global Intangible Low Tax Income as a period cost.
Foreign Currency	Foreign Currency:
Pension and Other Postretirement Benefits	Pension and Other Postretirement Benefits:
Stock-Based Compensation	Stock-Based Compensation: The Company recognizes stock-based compensation expense over the related vesting period of the awards based on the fair value on the grant date. Stock options are issued with an exercise price equal to the opening market price of Timken common shares on the date of grant. The fair value of stock options is determined using a Black-Scholes option pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate and the expected dividend yield. The fair value of stock-based awards that will settle in Timken common shares, other than stock options, is based on the opening market price of Timken common shares on the grant date. The fair value of stock-based awards that will settle in cash are remeasured at each reporting period until settlement of the awards. The Company recognizes forfeitures on stock-based awards as they occur.
Earnings Per Share	Earnings Per Share: Earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the year. Diluted earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding, adjusted for the dilutive impact of potential common shares for share-based compensation awards.
Derivative Instruments	Derivative Instruments: The Company recognizes all derivatives on the Consolidated Balance Sheets at fair value. Derivatives that are not designated as hedges are adjusted to fair value through earnings. If the derivative is designated and qualifies as a hedge, depending on the nature of the hedge, changes in the fair value of the derivatives are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in accumulated other comprehensive loss (income) until the hedged item is recognized in earnings. The Company’s holdings of forward foreign currency exchange contracts qualify as derivatives pursuant to the criteria established in derivative accounting guidance, and the Company has designated certain of those derivatives as hedges.
Use of Estimates	Use of Estimates: The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Because actual results could differ from these estimates, the Company reviews and updates these estimates and assumptions regularly to reflect recent experience.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: New Accounting Guidance Adopted: In November 2023, the FASB issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280). ASU 2023-07 requires that a public entity disclose: (1) on an annual and interim basis, significant segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM") and included within each reported measure of segment profit or loss; (2) on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition; and (3) the title and position of the CODM and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. The other segment items category is the difference between segment revenue less the segment expenses disclosed and each reported measure of segment profit or loss. For public business entities, the new guidance is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted the new guidance in the fourth quarter of 2024. Refer to Note 4 - Segment Information in the Notes to the Consolidated Financial Statements for additional information. New Accounting Guidance Issued and Not Yet Adopted: In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). ASU 2024-03 requires that a public entity disclose the detailed information about types of expense. Specifically, a public entity would disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation and (d) intangible asset amortization included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)–(d). In addition, a public entity should include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements. A public entity would also disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. For public business entities, the new guidance is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 40). ASU 2023-09 is intended to enhance the transparency and decision to improve the usefulness of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. The amendments require that all entities disclose on an annual basis the amount of income taxes paid disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts exceed a quantitative threshold. For public business entities, the new guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is preparing to adopt the new guidance in 2025.
Government Assistance	From time to time, the Company receives government assistance in the form of grants and other incentives from various governments to support capital projects and other business development. The amounts received are typically based on the amount of qualifying capital expenditures or business development costs in the countries providing the government assistance. The Company typically has to meet certain requirements, such as adding or maintaining a specified number of qualifying positions, to retain the government assistance or the funds can be clawed back by the government. Once the Company determines that it will meet the requirements of the government assistance, the funds are recognized over the life of the related assets or as the costs are incurred. For amounts that are expected to be paid back, the Company recognizes applicable interest expense.
