DESCRIPTION OF THE BUSINESS

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
DESCRIPTION OF THE BUSINESS DESCRIPTION OF THE BUSINESS
Atmus Filtration Technologies Inc. (“Atmus” or the “Company”) is one of the global leaders of filtration products for on-highway commercial vehicles and off-highway agriculture, construction, mining and power generation vehicles and equipment. Atmus designs and manufactures advanced filtration products, principally under the Fleetguard brand, that provide superior asset protection and enable lower emissions. Approximately 14% of Atmus’ net sales in 2024 were generated through first-fit sales to OEMs, where its products are installed as components for new vehicles and equipment. Approximately 86% of Atmus’ net sales in 2024 were generated in the aftermarket, where its products are installed as replacement or repair parts, leading to a strong recurring revenue base. Building on its more than 65-year history, Atmus continues to grow and differentiate itself through its global footprint, comprehensive offering of premium products, technology leadership and multi-channel path to market.
In April 2022, Cummins Inc. (“Cummins”) announced its intention to separate its filtration business (the “Filtration Business”) into a standalone publicly traded company (the “Separation”). In preparation for the Separation from Cummins, Atmus, as its predecessor in interest, was incorporated as a wholly-owned subsidiary of Cummins in Delaware on April 1, 2022 in connection with the planned Separation. Prior to the completion of Atmus’ initial public offering (the “IPO”), Cummins completed, in all material respects, the transfer of the assets and liabilities of the Filtration Business to Atmus and its subsidiaries as detailed in the separation agreement Atmus entered into with Cummins.
On September 30, 2022, and as amended on February 15, 2023, Atmus entered into a $1.0 billion credit agreement (“Credit Agreement”) with a syndicate of banks, providing for a $600 million term loan facility (the “term loan”) and a $400 million revolving credit facility (the “revolving credit facility”), in anticipation of the Separation. Borrowings under the Credit Agreement did not become available until the IPO occurred. The facilities covered by the Credit Agreement will mature on September 30, 2027.
Atmus’ Registration Statement on Form S-1, as amended, filed with the Securities and Exchange Commission (“Commission”) on May 16, 2023, was declared effective on May 25, 2023, and Atmus’ common shares began trading on the New York Stock Exchange under the symbol “ATMU” on May 26, 2023. On May 30, 2023, the IPO was completed through the sale on behalf of certain commercial paper holders of Cummins of 16,243,070 shares of common stock, including the underwriters’ full exercise of their 30-day option to purchase an additional 2,118,661 shares to cover over-allotments. None of the proceeds of the IPO were for the benefit of Atmus. As of the closing of the IPO, Cummins owned approximately 80.5% of the outstanding shares of Atmus common stock.
Upon completion of the IPO, Atmus borrowed $650 million, consisting of proceeds of the term loan and amounts drawn under the revolving credit facility, and paid such amounts to Cummins in partial consideration for the Separation.
On February 14, 2024, Cummins announced an exchange offer whereby Cummins shareholders could exchange all or a portion of Cummins common stock for shares of Atmus common stock owned by Cummins. The divestiture of Atmus shares by Cummins was completed on March 18, 2024 and resulted in the full separation of Atmus and divestiture of Cummins’ entire ownership and voting interest in Atmus (“Full Separation”).

BASIS OF PRESENTATION
12 Months Ended
Dec. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]  
BASIS OF PRESENTATION BASIS OF PRESENTATION
As Atmus became a publicly traded company upon the IPO, its financial statements are now presented on a consolidated basis. In preparation for the IPO, the Company’s historical combined financial statements were prepared on a standalone basis, which reflected a combination of entities under common control that had been “carved out” of and derived from the historical consolidated financial statements and accounting records of Cummins.
The financial statements for all periods presented, including the historical results of the Company prior to May 26, 2023, are now referred to as “Consolidated Financial Statements”, and have been prepared in
accordance with generally accepted accounting principles in the United States of America (GAAP). All intercompany balances and transactions are eliminated in consolidation.
Periods Prior to the IPO
Prior to the IPO, Atmus, previously the Filtration Business of Cummins, functioned as part of the larger group of businesses controlled by Cummins and accordingly, utilized centralized functions of Cummins, such as facilities and information technology, to support its operations. A portion of the shared service costs were historically allocated to the Filtration Business. Cummins also performed certain corporate functions for the Filtration Business. The corporate expenses related to the Filtration Business were allocated from Cummins. These allocated costs primarily related to certain governance and corporate functions, including finance, human resources, investor relations, legal, tax, treasury and certain other costs. Where it was possible to specifically attribute such expenses to activities of the Filtration Business, these amounts were charged or credited directly to the Filtration Business without allocation or apportionment. Allocation of other such expenses was based on a reasonable reflection of the utilization of the service provided or benefit received by the Filtration Business for the periods presented prior to the Separation, on a consistent basis, such as a relative percentage of headcount and third-party sales. The aggregate costs allocated for these functions to the Filtration Business are included within the Consolidated Statements of Net Income for the periods presented prior to the Separation.
Management believes these cost allocations were a reasonable reflection of the utilization of services provided to, or the benefit derived by, the Filtration Business during the period prior to the IPO, though the allocations may not be indicative of the actual costs that would have been incurred had the Filtration Business operated as a standalone public company. Actual costs that may have been incurred if the Filtration Business had been a standalone company would depend on a number of factors, including the chosen organizational structure, whether functions were outsourced or performed by the Filtration Business employees, and strategic decisions made in areas such as manufacturing, selling and marketing, research and development, information technology and infrastructure.
Historically, Atmus’ cash was transferred to Cummins on a daily basis. This arrangement was not reflective of the manner in which Atmus would have been able to finance its operations had it been a standalone business separate from Cummins during each of the periods presented.
Cummins’ debt and related interest expense were not allocated to Atmus for any of the periods presented since Atmus was not the legal obligor of the debt and Cummins’ borrowings were not directly attributable to Atmus.
As the separate legal entities that made up the Filtration Business were not historically held by a single legal entity, Cummins’ net investment in this business (“Net Parent Investment”) was presented in lieu of a controlling interest’s equity in the Consolidated Financial Statements.
For the Filtration Business, transactions with Cummins affiliates were included in the Consolidated Statements of Net Income and related balances were reflected as related party receivables and related party payables. Other balances between the Filtration Business and Cummins were considered to be effectively settled in the Consolidated Financial Statements at the time the transactions were recorded.
As of the IPO Date
In connection with the Separation, Atmus entered into various agreements with Cummins, including a separation agreement. In the separation agreement, there were certain assets and liabilities identified in the schedules, including leases and unrecognized tax liabilities, which were retained by Cummins and were reflected as Net Parent Investment in the Company’s Consolidated Financial Statements, and those that were transferred to the Company, including additional pension assets, other compensation obligations and certain other assets and liabilities, which were transferred to the Company through Net Parent Investment in the Company’s Consolidated Financial Statements. These various agreements comprehensively provide a
framework for our relationship with Cummins and govern various interim and ongoing relationships between us and Cummins post IPO.
As part of the Separation, Net Parent Investment was reclassified as Additional Paid-in Capital.
Periods Post IPO
Following the IPO, certain services continue to be provided by Cummins under the transition services agreement. The Company incurred certain costs in its establishment as a standalone public company and expects to incur ongoing additional costs associated with operating as an independent, publicly traded company.
Post IPO, Atmus filed a consolidated Federal income tax return and returns in certain other jurisdictions with Cummins.
Post IPO, Retained earnings began to accumulate and the balance reflected on the Consolidated Balance Sheets reflects earnings for the period May 26, 2023 through December 31, 2024.
Periods Post Full Separation
Following Full Separation, Cummins will continue to provide certain services to Atmus under the transition services agreement. The transition services agreement relates primarily to administrative services, which are expected to be completed by August 2025. Atmus will continue to pay Cummins mutually agreed upon fees for these services.
Post Full Separation, Cummins is no longer considered a related party and activity post March 18, 2024, between Atmus and Cummins has been treated as arm’s-length transactions.

Atmus files tax returns in all jurisdictions on its own behalf post Full Separation, and tax balances and effective income tax rates may differ from the amounts reported in the historical periods.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Investments in Equity Investees
We use the equity method to account for our investments in joint ventures, affiliated companies and alliances in which we have the ability to exercise significant influence, generally represented by equity ownership or partnership equity of at least 20 percent but not more than 50 percent. Generally, under the equity method, original investments in these entities are recorded at cost and subsequently adjusted by our share of equity in income or losses after the date of acquisition. Equity in income or losses of each investee is recorded according to our level of ownership; if losses accumulate, we record our share of losses until our investment has been fully depleted. If our investment has been fully depleted, we recognize additional losses only when we are the primary funding source. We eliminate (to the extent of our ownership percentage) in our Consolidated Financial Statements the profit in inventory held by our equity method investees that has not yet been sold to a third-party. Dividends received from equity method investees reduce the amount of our investment when received and do not impact our earnings. Our investments are classified as “Investments and advances related to equity method investees” in our Consolidated Balance Sheets. Our share of the results from joint ventures, affiliated companies and alliances is reported in our Consolidated Statements of Net Income as “Equity, royalty and interest income from investees” and is reported net of all applicable income taxes. Our foreign equity investees are presented net of applicable foreign income taxes in our Consolidated Statements of Net Income. See Note 5, Investments in Equity Investees, for additional information.
Use of Estimates in the Preparation of the Consolidated Financial Statements
Preparation of financial statements requires management to make estimates and assumptions that affect reported amounts presented and disclosed in our Consolidated Financial Statements. Significant estimates and assumptions in these Consolidated Financial Statements require the exercise of judgment and are used for, but not limited to, estimates of future cash flows and other assumptions associated with goodwill and long-lived asset impairment tests, useful lives for depreciation and amortization, warranty programs, restructuring costs, income taxes, deferred tax valuation allowances, contingencies and allowances for doubtful accounts. Due to
the inherent uncertainty involved in making estimates, actual results reported in future periods may be different from these estimates.
Revenue From Contracts with Customers
Revenue Recognition Sales of Products
We sell to customers either through long-term arrangements or standalone purchase orders. Our long-term arrangements generally do not include committed volumes until underlying purchase orders are issued. Typically, we recognize revenue on the products we sell at a point in time, in accordance with shipping terms or other contractual arrangements. All related shipping and handling costs are accrued at the time the related performance obligation has been satisfied.
Our sales arrangements may include the collection of sales and other similar taxes that are then remitted to the related taxing authority. We have elected to present the amounts collected for these taxes net of the related tax expense rather than presenting them as additional revenue.
We grant credit limits and terms to customers based upon traditional practices and competitive conditions. Typical terms vary by market, but payments are generally due in 60 days or less from invoicing for most of our product sales.
Sales Incentives
We provide various sales incentives to both our distribution network and OEM customers. These programs are designed to promote the sale of our products or encourage the usage of our products by OEM customers. When there is uncertainty surrounding these sales incentives, we may reduce the amount of revenue we recognize under a contract through an incentive accrual. When the uncertainty has been resolved the accrual will be adjusted accordingly. Sales incentives primarily fall into three categories:
Aftermarket rebates;
Volume and growth rebates; and
Marketing Development Fund (“MDF”).
For aftermarket rebates, we provide incentives to promote sales to certain dealers and end-markets. These rebates are typically paid on a quarterly, or more frequent, basis. At the time of the sale, we consider the expected amount of these rebates when determining the overall transaction price. Estimates are adjusted at the end of each month or quarter based sales and historical experience.
For volume and growth rebates, we provide certain customers with rebate opportunities for attaining specified volumes during a particular quarter or year. We consider the expected amount of these rebates at the time of the original sale as we determine the sales revenue. We update our assessment of the amount of rebates that will be earned on a monthly or quarterly basis based on our best estimate of the volume levels the customer will reach during the measurement period.
For MDF’s, these are funds to support our customers primarily for business development, marketing and advertising programs, promotional items jointly developed, dealer incentives and partnering programs. Depending on the agreement, the funds are accrued for and paid on a quarterly basis, annual basis, or as agreed with those customers receiving these funds.
Sales Returns
The initial determination of the sales revenue may also be impacted by product returns. Rights of return do not exist for the majority of our sales other than for quality issues. We do offer certain return rights in our aftermarket business, where some aftermarket customers are permitted to return a small amount of filters each year. An estimate of future returns is accounted for at the time of sale as a reduction in the overall sales revenue based on historical return rates.
Foreign Currency Transactions and Translation
We translate assets and liabilities of foreign entities to U.S. dollars, where the local currency is the functional currency, at month-end exchange rates. We translate income and expenses to U.S. dollars using weighted-average exchange rates. We record adjustments resulting from translation in a separate component of accumulated other comprehensive loss and include the adjustments in net income only upon sale, loss of controlling financial interest or liquidation of the underlying foreign investment.
Foreign currency transaction gains and losses are included in net income. For foreign entities where the U.S. dollar is the functional currency, including those operating in highly inflationary economies when applicable, we remeasure non-monetary balances and the related income statement amounts using historical exchange rates. We include the resulting gains and losses in net income, including the effect of derivatives in our Consolidated Statements of Net Income, which combined with transaction gains (losses) amounted to $2.8 million, $(3.3) million and $0.3 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Income Tax Accounting
We determine our income tax expense using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax effects of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Future tax benefits of net operating loss and credit carryforwards are also recognized as deferred tax assets. We evaluate the recoverability of our deferred tax assets each quarter by assessing the likelihood of future profitability and available tax planning strategies that could be implemented to realize our net deferred tax assets. A valuation allowance is recorded to reduce the tax assets to the net value management believes is more likely than not to be realized. In the event our operating performance deteriorates, future assessments could conclude that a larger valuation allowance will be needed to further reduce the deferred tax assets. In addition, we operate within multiple taxing jurisdictions and are subject to tax audits in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve. We accrue for the estimated additional tax and interest that may result from tax authorities disputing uncertain tax positions. We believe we made adequate provisions for income taxes for all years that are subject to audit based upon the latest information available.
Our income tax provision was prepared following the separate return method, which applies Accounting Standards Codification (“ASC”) 740 to the standalone financial statements of each member of the combined group as if the group member were a separate and standalone enterprise. Due to this treatment, tax transactions included in the Consolidated Financial Statements of the Parent may not be included in the separated Consolidated Financial Statements of the Company. Similarly, there may be certain tax attributes within the Consolidated Financial Statements of the Company that would not be found in the Consolidated Financial Statements and tax returns of the Parent. Examples of such items include net operating losses, tax credits carry forwards and valuation allowances, which may exist in the standalone financial statements but not in the Parent’s Consolidated Financial Statements.
The international tax framework introduced by the Organization for Economic Co-operation and Development under its Pillar Two initiative includes a global minimum tax of 15 percent. Legislation adopting these provisions has been enacted in certain jurisdictions where the Company operates and is effective for the Company's 2024 fiscal year. The Company has assessed this legislation and the Pillar Two provisions do not have a material impact on the Company’s tax expense.
A more complete description of our income taxes and the future benefits of our net operating loss and credit carryforwards is disclosed in Note 6, Income Taxes.

Cash and Cash Equivalents

Cash and cash equivalents consist of bank checking accounts and money market accounts. Atmus considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents are carried at cost, which approximates fair value.
Accounts Receivable and Allowance for Doubtful Accounts
Trade accounts receivable represent amounts billed to customers and not yet collected or amounts that have been earned but may not be billed until the passage of time and are recorded when the right to consideration becomes unconditional. Trade accounts receivable are recorded at the invoiced amount, which approximates net realizable value and generally do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of expected credit losses in our existing accounts receivable. We determine the allowance based on our historical collection experience and by performing an analysis of our accounts receivable in light of the current economic environment. This estimate of expected losses reflects those losses expected to occur over the contractual life of the receivable. We review our allowance for doubtful accounts at least quarterly, and more frequently as needed. In addition, when necessary, we provide an allowance for the full amount of specific accounts deemed to be uncollectible. Account balances are charged off against the allowance in the period in which we determine that it is probable the receivable will not be recovered. The allowance for doubtful accounts balances were $3.0 million and $2.9 million at December 31, 2024 and 2023, respectively. Bad debt write-offs were not material during the three years ended December 31, 2024.
Inventories
Our inventories are stated at the lower of cost or net realizable value. As of December 31, 2024 and 2023, approximately 30.3% and 32.1%, respectively, of our inventories were valued using the last-in, first-out (LIFO) cost method. The cost of other inventories is generally valued using the first-in, first-out (FIFO) cost method. Our inventories include estimates for adjustments related to annual physical inventory results and for inventory cost changes under the LIFO cost method. Due to significant movements of partially-manufactured components and parts between manufacturing plants, we do not internally measure, nor do our accounting systems provide, a meaningful segregation between raw materials and work-in-process. See Note 7, Inventories, for additional information.
Property, Plant and Equipment
We record property, plant and equipment at cost, inclusive of finance lease assets, with the adoption of ASC 842. We depreciate the cost of the majority of our property, plant and equipment using the straight-line method with depreciable lives ranging from 20 to 40 years for buildings and 3 to 15 years for machinery, equipment and fixtures. Finance lease asset amortization is recorded in depreciation expense. We expense normal maintenance and repair costs as incurred. Depreciation expense totaled $24.8 million, $21.5 million and $20.7 million for the years ended December 31, 2024, 2023 and 2022, respectively. See Note 8, Property, Plant and Equipment and Note 9, Leases, for additional information.
Impairment of Long-Lived Assets
We review our long-lived assets for possible impairment whenever events or circumstances indicate that the carrying value of an asset or asset group may not be recoverable. We assess the recoverability of the carrying value of the long-lived assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. An impairment of a long-lived asset or asset group exists when the expected future pre-tax cash flows (undiscounted and without interest charges) estimated to be generated by the asset or asset group is less than its carrying value. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is measured based on the difference between the estimated fair value and carrying value of the asset or asset group. Assumptions and estimates used to estimate cash flows in the evaluation of impairment and the fair values used to determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying value of long-lived assets and could result in a future impairment charge.
Leases
We determine if an arrangement contains a lease in whole or in part at the inception of the contract. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. All leases greater than 12 months result in the recognition of a ROU asset and a liability at the lease commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide the information required to determine the implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. This rate is determined considering
factors such as the lease term, our credit standing and the economic environment of the location of the lease. We use the implicit rate when readily determinable.
Our lease terms include all non-cancelable periods and may include options to extend (or to not terminate) the lease when it is reasonably certain that we will exercise that option. Leases that have a term of 12 months or less at the commencement date are expensed on a straight-line basis over the lease term and do not result in the recognition of an asset or a liability.
Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense for finance leases is generally front-loaded as the finance lease ROU asset is depreciated on a straight-line basis, but interest expense on the liability is recognized utilizing the interest method that results in more expense during the early years of the lease. We have lease agreements with lease and non-lease components, primarily related to real estate, vehicle and information technology (“IT”) assets. For vehicle and real estate leases, we account for the lease and non-lease components as a single lease component. For IT leases, we allocate the payment between the lease and non-lease components based on the relative value of each component. See Note 9, Leases, for additional information.
Goodwill
We have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform an annual quantitative goodwill impairment test. We have elected this option for our reporting unit. In addition, the carrying value of goodwill must be tested for impairment on an interim basis in certain circumstances where impairment may be indicated.
When we are required or opt to perform the quantitative impairment test, the fair value of our reporting unit is estimated with either the market approach or the income approach using a discounted cash flow model. Our income approach method uses a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate of return.
The discounted cash flow model requires us to make projections of revenue, gross margin, operating expenses, working capital investment and fixed asset additions for our reporting unit over a multi-year period. Additionally, management must estimate a weighted-average cost of capital, which reflects a market rate, for our reporting unit for use as a discount rate. The discounted cash flows are compared to the carrying value of the reporting unit and, if less than the carrying value, the difference is recorded as a goodwill impairment loss. In addition, we also perform a sensitivity analysis to determine how much our forecasts can fluctuate before the fair value of a reporting unit would be lower than its carrying amount.
We perform the required procedures as of the end of our fiscal third quarter.
Changes in our projections or estimates, a deterioration of our operating results and the related cash flow effect or a significant increase in the discount rate could decrease the estimated fair value of our reporting unit and result in a future impairment of goodwill. See Note 10, Goodwill, for additional information.
Warranty
We estimate and record a liability for standard warranty programs at the time our products are sold. Our estimates are based on historical experience and reflect management’s best estimates of expected costs at the time products are sold and subsequent adjustment to those expected costs when actual costs differ. As a result of the uncertainty surrounding the nature and frequency of product campaigns, the liability for such campaigns is recorded when we commit to a recall action or when a recall becomes probable and estimable, which generally occurs when it is announced. We review and assess the liability for these programs on a quarterly basis. See Note 11, Product Warranty Liability, for additional information.
Research, Development and Engineering
Our research, development and engineering programs are focused on product improvements, product extensions, innovations and cost reductions for our customers. Research, development and engineering expenditures include salaries, contractor fees, building costs, utilities, testing, technical IT, administrative
expenses and allocation of corporate costs and are expensed, net of contract reimbursements, when incurred. Research, development and engineering expenses were $40.6 million, $42.5 million and $38.6 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Related Party Transactions
In accordance with the provisions of various joint venture agreements, we may purchase products and components from our joint ventures, sell products and components to our joint ventures and our joint ventures may sell products and components to unrelated parties. Joint venture transfer prices may differ from normal selling prices. Certain joint venture agreements transfer product at cost, some transfer product on a cost-plus basis, and others transfer product at market value. These purchases and sales take place on terms resulting in margins within a reasonable range of market rates. See Note 17, Relationship with Parent and Related Parties, for additional information.
Segment Information
We operate our business as one operating segment and also one reportable segment based on the manner in which we review and evaluate operating performance. The types of products from which revenue is derived are the same as those described in the description of the business section and the accounting policies are the same as those described in the summary of significant accounting policies.
The operating results are regularly reviewed by Atmus’ chief operating decision maker on a consolidated basis. The chief operating decision maker is our Chief Executive Officer. The chief operating decision maker assesses performance for our business and decides how to allocate resources based on net income that also is reported on the income statement as consolidated net income and is regularly provided with consolidated expense information from the income statement. The measurement of business assets is reported on the balance sheet as total consolidated assets.
The chief operating decision maker uses net income predominately in the annual budget and forecasting process. The chief operating decision maker considers budget-to-actual in deciding whether to reinvest profit into the operating segment or for other entity initiatives, such as acquisitions, paying dividends, or share repurchases. The chief operating decision maker also uses the profit or loss measure for determining compensation of certain employees.
Stock-Based Compensation
We maintain a share-based compensation plan, which authorizes the granting of various equity-based incentives, including restricted stock units (“RSU”s) and performance share units (“PSU”s). Stock compensation expense is generally amortized on a straight line basis over the service period during which awards are expected to vest, generally three years.
RSUs are typically granted to selected employees on an annual basis and vest over three years. Dividend equivalents are paid during the vesting period. The fair value of our RSUs and other stock-based awards is measured at the market price of our Common Stock on the grant date.
PSUs vest based on varying performance, market and service conditions. The fair value of our PSUs is measured at the market price of our Common Stock on the grant date. The final award may equal 0-200 percent of the target grant, based on our actual performance during the vesting period.
Forfeitures are estimated on the grant date for all of our stock-based compensation awards.
Pensions and other Postretirement Benefits
Atmus provides a range of benefits, including pensions, postretirement and post-employment benefits to eligible current and former employees, of which certain of our employees participate. For purposes of Atmus’ Consolidated Financial Statements, participation in Atmus plans are treated as single-employer plans. See Note 13, Pensions and Other Postretirement Benefits, for more information.
Net Parent Investment
Net Parent Investment represents Cummins’ historical investment in us, our accumulated net earnings after taxes and the net effect of transactions with and allocations from Cummins prior to the IPO.
The Consolidated Statements of Changes in Equity include net cash transfers between Cummins and Atmus pursuant to the centralized cash management and other treasury-related functions performed by Cummins for the periods prior to the IPO. The Net Parent Investment account includes the settlement and net effect of transactions with and corporate allocations from Cummins including administrative expenses such as corporate finance, accounting and field shared services, information services, human resources, marketing, corporate office and other services.
In the separation agreement, there were certain assets and liabilities which were retained by Cummins and were reflected as Net Parent Investment in the Company’s Consolidated Financial Statements, and those that were transferred to the Company through Net Parent Investment in the Company’s Consolidated Financial Statements.
The net effect of other assets and liabilities and related income and expenses recorded at the corporate level and pushed down to Atmus are also included in Net Parent Investment.
All transactions reflected in Net Parent Investment in the historical Consolidated Balance Sheets have been considered cash receipts and payments for purposes of the Consolidated Statements of Cash Flows and are reflected in financing activities in the accompanying Consolidated Statements of Cash Flows with the exception of certain non-cash items related to an unrecognized tax liability for FIN48 reserves and leased assets and related depreciation, which were retained by Cummins upon completion of Atmus’ IPO. These items have been included as supplemental information to the Consolidated Statements of Cash Flows.
Recent Accounting Pronouncements
Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. We adopted this standard in the fourth quarter of 2024 and it did not have a material impact on our disclosures and no impacts to our results of operations, cash flows and financial condition.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, that requires entities to disclose additional information about federal, state, and foreign income taxes primarily related to the income tax rate reconciliation and income taxes paid. The new standard also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The guidance is effective for our fiscal year ending December 31, 2025, with early adoption permitted. The guidance does not affect recognition or measurement in our consolidated financial statements. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.
Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement
Expenses, which requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the consolidated financial statements. The guidance is effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The guidance is to be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. We are currently evaluating the potential impact of adopting this new guidance on our consolidated financial statements and related disclosures.

Our effective tax rate for 2024 was 21.0%, compared to 24.3% for 2023 and 19.6% for 2022. The decrease in the effective tax rate was driven by a favorable change in the mix of earnings among tax jurisdictions and discrete tax items related to US and foreign tax return filings.
At December 31, 2024, $199.5 million of non-U.S. earnings are considered indefinitely reinvested in operations outside the U.S. for which deferred taxes have not been provided. Determination of the related deferred tax liability, if any, is not practicable because of the complexities associated with the hypothetical calculation.

A valuation allowance is recorded to reduce the gross deferred tax assets to an amount we believe is more likely than not to be realized. The valuation allowance is primarily attributable to the uncertainty regarding the realization of foreign net operating loss, foreign currency loss and foreign tax credits.

The total amount of unrecognized tax benefits in 2024, 2023 and 2022, if recognized, would favorably impact the effective tax rate in future periods.
We have accrued interest expense related to the unrecognized tax benefits of $0 million, $0 million and $7.0 million as of December 31, 2024, 2023 and 2022, respectively. We recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.
Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Although we believe that adequate provision has been made for such issues, there is the possibility that the ultimate
resolution of such issues could have an adverse effect on our earnings. Conversely, if these issues are resolved favorably in the future, the related provision would be reduced, thus having a positive impact on earnings.
As a result of our global operations, we file income tax returns in various jurisdictions including U.S. federal, state and foreign jurisdictions. We are routinely subject to examination by taxing authorities throughout the world, including Australia, Belgium, Brazil, Canada, China, France, India, Mexico, the U.K. and the U.S. With few exceptions, our U.S. federal, major state and foreign jurisdictions are no longer subject to income tax assessments for years before 2020.

Leases [Abstract]  
LEASES LEASES
Our lease portfolio consists primarily of real estate and equipment leases. Our real estate leases primarily consist of land, office, distribution, warehousing and manufacturing facilities. These leases typically range in term from 2 to 50 years and may contain renewal options for periods up to 10 years at our discretion. Our equipment lease portfolio consists primarily of vehicles, fork trucks and IT equipment. These leases typically range in term from two years to three years and may contain renewal options. Our leases generally do not contain variable lease payments other than (1) certain foreign real estate leases which have payments indexed to inflation and (2) certain real estate executory costs (such as taxes, insurance and maintenance), which are paid based on actual expenses incurred by the lessor during the year. Our leases generally do not include residual value guarantees.
Our operating lease cost was $15.7 million, $10.5 million, and $10.7 million for the years ended December 31, 2024, 2023 and 2022, respectively. Our variable lease cost was $1.0 million for the year ended December 31, 2024 and was immaterial for the years December 31, 2023 and 2022. Our finance lease cost and short-term lease cost were immaterial for the years ended December 31, 2024, 2023 and 2022.

Debt Disclosure [Abstract]  
DEBT AND BORROWING ARRANGEMENTS DEBT AND BORROWING ARRANGEMENTS
Atmus entered into the Credit Agreement with a syndicate of banks, providing for a term loan and a revolving credit facility, in anticipation of the Separation. Borrowings under the Credit Agreement did not become available under the Credit Agreement until the IPO occurred. The facilities covered by the Credit Agreement will mature on September 30, 2027.
Upon completion of the IPO, we borrowed $650 million under the Credit Agreement, consisting of proceeds of the term loan and amounts drawn under the revolving credit facility, and paid such amounts to Cummins in partial consideration for the Separation.
Borrowings under the Credit Agreement bear interest at varying rates, depending on the type of loan and, in some cases, the rates of designated benchmarks and the applicable election made. Generally, U.S. dollar-denominated loans bear interest at an adjusted term Secured Overnight Financing Rate (“SOFR”) (which
includes a 0.10 percent credit spread adjustment to SOFR) for the applicable interest period plus a rate ranging from 1.125 percent to 1.75 percent depending on Atmus’ net leverage ratio. As of December 31, 2024, $592.5 million has been drawn on the term loan and no amount was drawn on the revolving credit facility. The revolving credit facility includes an allowance of up to $50.0 million for outstanding letters of credit drawn under the facility that reduces the availability of funds. As of December 31, 2024, no letters of credit were outstanding. These amounts are included within Long-term debt and Current maturities of long-term debt on the Balance Sheet. As of December 31, 2024, Atmus’ fair value of Long-term debt was approximately $592.5 million, which was derived from Level 2 input measures.

Atmus Plans
Atmus has defined benefit pension plans, which provide retirement benefits to eligible participants and are collectively referred to as the “Atmus Plans.” The plans’ benefits are primarily based on employee earnings and credited service.
Plans in two countries, Belgium and Mexico, were newly established in 2023.
The total Atmus Plans’ defined benefit pension plan expenses were $1.7 million in 2024, $0.9 million in 2023 and $2.0 million in 2022. Service costs allocated to Atmus were $1.3 million in 2024, $0.6 million in 2023 and $1.5 million in 2022. These costs are reflected in the Consolidated Financial Statements as a component of Cost of sales, Research, development and engineering expenses and Selling, general and administrative expenses. The non-service costs allocated to Atmus were immaterial for each of the years ended December 31, 2024, 2023 and 2022. These non-service costs are reflected in the Consolidated Financial Statements as a component of Other income, net.
The aggregate status of all over funded plans is recognized as an asset and the aggregate status of all underfunded plans is recognized as a liability in the Consolidated Balance Sheets. The liabilities were $11.0 million and $9.6 million as of December 31, 2024 and 2023, respectively, and are reflected in the Consolidated Financial Statements as a component of Other liabilities. The current portion of the liabilities were immaterial as of December 31, 2024 and 2023. The amounts recognized as assets were $2.1 million and $0 million as of December 31, 2024 and 2023, respectively, and are reflected in the Consolidated Financial Statements as a component of Other assets.

Legal Proceedings
The Company is subject to lawsuits and claims arising out of the ordinary course of its business. The Company does not have any currently pending claims or litigation that the Company believes, individually or in the aggregate, will have a material adverse effect on its financial position, results of operations, cash flows, liquidity or capital resources. Atmus carries various forms of commercial, property and casualty, product liability and other forms of insurance; however, such insurance may not be applicable or adequate to cover the costs associated with a judgment against Atmus with respect to these lawsuits, claims and proceedings. While the Company believes it has established adequate accruals for our expected future liability with respect to pending lawsuits, claims and proceedings, where the nature and extent of any such liability can be reasonably estimated based upon presently available information, there can be no assurance that the final resolution of any existing or future lawsuits, claims or proceedings will not have a material adverse effect on Atmus’ business, results of operations, financial condition or cash flows.
Indemnifications
Periodically, Atmus enters various contractual arrangements where it agrees to indemnify a third-party against certain types of losses. Atmus regularly evaluates the probability of having to incur costs associated with these indemnities and accrue for expected losses that are probable. Because the indemnifications are not related to specified known liabilities, and due to their uncertain nature, Atmus is unable to estimate the maximum amount of the potential loss associated with these indemnifications.

Related Party Transactions [Abstract]  
RELATIONSHIP WITH RELATED PARTIES RELATIONSHIP WITH RELATED PARTIES
As described in Note 1, Description of the Business, Atmus had been managed and operated in the normal course of business with other subsidiaries of Cummins until March 18, 2024, when the Full Separation was completed. Accordingly, certain shared costs prior to the IPO have been allocated to Atmus and reflected as expenses in the Consolidated Financial Statements. Management of Cummins and Atmus consider the allocation methodologies used to be reasonable and appropriate reflections of historical expenses of Cummins attributable to Atmus for purposes of the Consolidated Financial Statements; however, the expenses reflected in the Consolidated Financial Statements may not be indicative of the actual expenses that would have been incurred during the periods presented if Atmus historically operated as a separate, stand-alone entity. In addition, the expenses reflected in the Consolidated Financial Statements may not be indicative of expenses that will be incurred in the future by Atmus.
The Company entered into the separation agreement and transition services agreement with Cummins, among other transaction agreements, all of which will govern the parties relationship following the IPO and Full Separation. This relationship includes services provided by Cummins to the Company for a fixed term on a service-by-service basis. We will pay Cummins mutually agreed-upon fees for the services provided under the transition services agreement. The fees paid to Cummins may not be indicative of costs for the same services provided by another provider.
Corporate Costs/Allocations
The Consolidated Financial Statements include corporate costs incurred by Cummins for services that were provided to or on behalf of Atmus for the period prior to IPO. Such costs represent shared services and infrastructure provided by Cummins, including administrative, finance, human resources, information technology, legal, and other corporate and infrastructure services.
The corporate costs reflected in the Consolidated Financial Statements consist of direct charges to the business and indirect allocations to Atmus. The costs that were directly charged to Atmus, such as the shared services for finance provided by Cummins Business Services, were primarily determined based on actual usage.
Indirect allocations are related to shared services and infrastructure provided by Cummins that would benefit Atmus but were not directly charged to Atmus in a manner discussed above. These corporate costs were allocated to Atmus using methods management believes are consistent and reasonable. The primary allocation factor was third-party revenue; however, other relevant metrics were also utilized based on the nature of the underlying activities. For example, headcount is used as the allocation driver to allocate the human resource departmental costs.
The expenses allocated and directly charged reflect all expenses that Cummins incurred on behalf of the Company. The expenses reflected in the Consolidated Financial Statements prior to the IPO may not be indicative of the actual expenses that would have been incurred during the period presented if Atmus historically operated as a separate, stand-alone entity. All corporate charges and allocations have been deemed paid by Atmus to Cummins in the period in which the cost was recognized in the Consolidated Statements of Income.
Total corporate costs allocated to Atmus were $0 million, $13.7 million and $45.0 million for the years ended December 31, 2024, 2023 and 2022, respectively. Allocated corporate costs are included in Net sales, Cost of sales, Selling, general and administrative expenses, Research, development and engineering expenses and Other income, net. Post-IPO, Atmus has and will continue to incur its own corporate costs associated with being a standalone publicly traded company.
Related Party Balances
Following the full separation, Cummins is no longer considered a related party. Atmus had trade receivables of $37.9 million for products sold to, and accounts payable of $54.8 million for products and services purchased in the ordinary course from Cummins as of December 31, 2023. Atmus’ sales to Cummins from January 1, 2024 through the date of full separation, March 18, 2024, were $65.4 million compared to $282.5 million and $302.2 million for the years ended December 31, 2023 and 2022, respectively.

EARNINGS PER SHARE EARNINGS PER SHARE
Basic net earnings per share (“EPS”) is computed by dividing net earnings by the weighted average number of outstanding common shares. Diluted net EPS reflects the increase in weighted average common shares outstanding that would result from the assumed exercise of outstanding stock incentive plan awards calculated using the treasury stock method.
Basic and diluted EPS were calculated as follows:

Basic and diluted EPS for the year ended December 31, 2022 was calculated using the shares of common stock that were issued and outstanding as of the completion of the IPO. For the periods prior to the IPO, it is assumed that there were no dilutive equity instruments as there were no equity awards of Atmus outstanding prior to the IPO. Post IPO, there were no anti-dilutive shares.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
We have established and implemented processes to assess, identify and manage material cybersecurity risks. Cybersecurity risks are assessed, identified, and managed by our Executive Director of Cybersecurity and Infrastructure, with direct supervision by our Vice President and Chief Information Officer (“CIO”) and with the assistance of our internal audit and legal teams. Our Executive Director of Cybersecurity and Infrastructure shares information regarding such risks with our management’s senior level information security council (the “Information Security Council”), which consists of our CIO, Senior Vice President and Chief Financial Officer, Vice President and Chief Technical Officer, Senior Vice President and Chief Legal Officer & Corporate Secretary (currently vacant), Vice President of Strategy and Director of Internal Audit & Enterprise Risk Management, and which supports the Audit Committee’s oversight of cybersecurity risk, including by providing regular reports on various cybersecurity matters.
We have in place robust physical, technical, administrative, and organizational controls for the securing of our information systems.
We maintain a comprehensive, risk-based, third-party risk management process to identify, assess and manage cybersecurity risks associated with third-party service providers. Third-party service providers undergo thorough pre-engagement due diligence, including security and privacy assessments. All contracts with such third-party service providers are required to contain security and data processing terms no less stringent than those employed by us in safeguarding our own data. Any third-party service providers with access to confidential or sensitive data are subject to ongoing oversight activities, including assessments and audits, throughout the lifetime of the engagement.
Additionally, we maintain an incident response plan (the “Incident Response Plan”), which establishes a comprehensive, effective, and repeatable process for identifying, escalating and responding to cybersecurity incidents. We test and evaluate the Incident Response Plan, including contingency and recovery plans, on a regular basis, and we develop, implement and review contingency and recovery plans for information systems, both internal and vendor managed. The results of such assessments drive changes and enhancements to
governance, policies, procedures, technologies, and partner decisions to continuously monitor and improve our cybersecurity risk management. The Information Security Council practices the procedures of the Incident Response Plan through tabletop exercises facilitated by external consultants. We also leverage third-party support, including vendors, consultants, and assessors, to analyze risk exposure, to identify remediation opportunities and to reduce our overall cybersecurity risk.
Previous cybersecurity incidents have not materially affected us, including our business strategy, financial condition, results of operations or cash flows. However, risks from cybersecurity threats, including but not limited to security breaches, computer malware, ransom attacks, other cyber-attacks, or other similar threats may materially affect us, including our business, financial condition, results of operations or cash flows.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
Investments in Equity Investees
Investments in Equity Investees
We use the equity method to account for our investments in joint ventures, affiliated companies and alliances in which we have the ability to exercise significant influence, generally represented by equity ownership or partnership equity of at least 20 percent but not more than 50 percent. Generally, under the equity method, original investments in these entities are recorded at cost and subsequently adjusted by our share of equity in income or losses after the date of acquisition. Equity in income or losses of each investee is recorded according to our level of ownership; if losses accumulate, we record our share of losses until our investment has been fully depleted. If our investment has been fully depleted, we recognize additional losses only when we are the primary funding source. We eliminate (to the extent of our ownership percentage) in our Consolidated Financial Statements the profit in inventory held by our equity method investees that has not yet been sold to a third-party. Dividends received from equity method investees reduce the amount of our investment when received and do not impact our earnings. Our investments are classified as “Investments and advances related to equity method investees” in our Consolidated Balance Sheets. Our share of the results from joint ventures, affiliated companies and alliances is reported in our Consolidated Statements of Net Income as “Equity, royalty and interest income from investees” and is reported net of all applicable income taxes. Our foreign equity investees are presented net of applicable foreign income taxes in our Consolidated Statements of Net Income.
Use of Estimates in the Preparation of the Consolidated Financial Statements
Use of Estimates in the Preparation of the Consolidated Financial Statements
Preparation of financial statements requires management to make estimates and assumptions that affect reported amounts presented and disclosed in our Consolidated Financial Statements. Significant estimates and assumptions in these Consolidated Financial Statements require the exercise of judgment and are used for, but not limited to, estimates of future cash flows and other assumptions associated with goodwill and long-lived asset impairment tests, useful lives for depreciation and amortization, warranty programs, restructuring costs, income taxes, deferred tax valuation allowances, contingencies and allowances for doubtful accounts. Due to
the inherent uncertainty involved in making estimates, actual results reported in future periods may be different from these estimates.
Revenue From Contracts with Customers
Revenue From Contracts with Customers
Revenue Recognition Sales of Products
We sell to customers either through long-term arrangements or standalone purchase orders. Our long-term arrangements generally do not include committed volumes until underlying purchase orders are issued. Typically, we recognize revenue on the products we sell at a point in time, in accordance with shipping terms or other contractual arrangements. All related shipping and handling costs are accrued at the time the related performance obligation has been satisfied.
Our sales arrangements may include the collection of sales and other similar taxes that are then remitted to the related taxing authority. We have elected to present the amounts collected for these taxes net of the related tax expense rather than presenting them as additional revenue.
We grant credit limits and terms to customers based upon traditional practices and competitive conditions. Typical terms vary by market, but payments are generally due in 60 days or less from invoicing for most of our product sales.
Sales Incentives
We provide various sales incentives to both our distribution network and OEM customers. These programs are designed to promote the sale of our products or encourage the usage of our products by OEM customers. When there is uncertainty surrounding these sales incentives, we may reduce the amount of revenue we recognize under a contract through an incentive accrual. When the uncertainty has been resolved the accrual will be adjusted accordingly. Sales incentives primarily fall into three categories:
Aftermarket rebates;
Volume and growth rebates; and
Marketing Development Fund (“MDF”).
For aftermarket rebates, we provide incentives to promote sales to certain dealers and end-markets. These rebates are typically paid on a quarterly, or more frequent, basis. At the time of the sale, we consider the expected amount of these rebates when determining the overall transaction price. Estimates are adjusted at the end of each month or quarter based sales and historical experience.
For volume and growth rebates, we provide certain customers with rebate opportunities for attaining specified volumes during a particular quarter or year. We consider the expected amount of these rebates at the time of the original sale as we determine the sales revenue. We update our assessment of the amount of rebates that will be earned on a monthly or quarterly basis based on our best estimate of the volume levels the customer will reach during the measurement period.
For MDF’s, these are funds to support our customers primarily for business development, marketing and advertising programs, promotional items jointly developed, dealer incentives and partnering programs. Depending on the agreement, the funds are accrued for and paid on a quarterly basis, annual basis, or as agreed with those customers receiving these funds.
Sales Returns
The initial determination of the sales revenue may also be impacted by product returns. Rights of return do not exist for the majority of our sales other than for quality issues. We do offer certain return rights in our aftermarket business, where some aftermarket customers are permitted to return a small amount of filters each year. An estimate of future returns is accounted for at the time of sale as a reduction in the overall sales revenue based on historical return rates.
Foreign Currency Transactions and Translation
Foreign Currency Transactions and Translation
We translate assets and liabilities of foreign entities to U.S. dollars, where the local currency is the functional currency, at month-end exchange rates. We translate income and expenses to U.S. dollars using weighted-average exchange rates. We record adjustments resulting from translation in a separate component of accumulated other comprehensive loss and include the adjustments in net income only upon sale, loss of controlling financial interest or liquidation of the underlying foreign investment.
Foreign currency transaction gains and losses are included in net income. For foreign entities where the U.S. dollar is the functional currency, including those operating in highly inflationary economies when applicable, we remeasure non-monetary balances and the related income statement amounts using historical exchange rates.
Income Tax Accounting
Income Tax Accounting
We determine our income tax expense using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax effects of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Future tax benefits of net operating loss and credit carryforwards are also recognized as deferred tax assets. We evaluate the recoverability of our deferred tax assets each quarter by assessing the likelihood of future profitability and available tax planning strategies that could be implemented to realize our net deferred tax assets. A valuation allowance is recorded to reduce the tax assets to the net value management believes is more likely than not to be realized. In the event our operating performance deteriorates, future assessments could conclude that a larger valuation allowance will be needed to further reduce the deferred tax assets. In addition, we operate within multiple taxing jurisdictions and are subject to tax audits in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve. We accrue for the estimated additional tax and interest that may result from tax authorities disputing uncertain tax positions. We believe we made adequate provisions for income taxes for all years that are subject to audit based upon the latest information available.
Our income tax provision was prepared following the separate return method, which applies Accounting Standards Codification (“ASC”) 740 to the standalone financial statements of each member of the combined group as if the group member were a separate and standalone enterprise. Due to this treatment, tax transactions included in the Consolidated Financial Statements of the Parent may not be included in the separated Consolidated Financial Statements of the Company. Similarly, there may be certain tax attributes within the Consolidated Financial Statements of the Company that would not be found in the Consolidated Financial Statements and tax returns of the Parent. Examples of such items include net operating losses, tax credits carry forwards and valuation allowances, which may exist in the standalone financial statements but not in the Parent’s Consolidated Financial Statements.
The international tax framework introduced by the Organization for Economic Co-operation and Development under its Pillar Two initiative includes a global minimum tax of 15 percent. Legislation adopting these provisions has been enacted in certain jurisdictions where the Company operates and is effective for the Company's 2024 fiscal year. The Company has assessed this legislation and the Pillar Two provisions do not have a material impact on the Company’s tax expense.
Cash and Cash Equivalents
Cash and Cash Equivalents

Cash and cash equivalents consist of bank checking accounts and money market accounts. Atmus considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents are carried at cost, which approximates fair value.
Accounts Receivable and Allowance for Doubtful Accounts
Accounts Receivable and Allowance for Doubtful Accounts
Trade accounts receivable represent amounts billed to customers and not yet collected or amounts that have been earned but may not be billed until the passage of time and are recorded when the right to consideration becomes unconditional. Trade accounts receivable are recorded at the invoiced amount, which approximates net realizable value and generally do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of expected credit losses in our existing accounts receivable. We determine the allowance based on our historical collection experience and by performing an analysis of our accounts receivable in light of the current economic environment. This estimate of expected losses reflects those losses expected to occur over the contractual life of the receivable. We review our allowance for doubtful accounts at least quarterly, and more frequently as needed. In addition, when necessary, we provide an allowance for the full amount of specific accounts deemed to be uncollectible. Account balances are charged off against the allowance in the period in which we determine that it is probable the receivable will not be recovered.
Inventories
Inventories
Our inventories are stated at the lower of cost or net realizable value. As of December 31, 2024 and 2023, approximately 30.3% and 32.1%, respectively, of our inventories were valued using the last-in, first-out (LIFO) cost method. The cost of other inventories is generally valued using the first-in, first-out (FIFO) cost method. Our inventories include estimates for adjustments related to annual physical inventory results and for inventory cost changes under the LIFO cost method. Due to significant movements of partially-manufactured components and parts between manufacturing plants, we do not internally measure, nor do our accounting systems provide, a meaningful segregation between raw materials and work-in-process.
Property, Plant and Equipment
Property, Plant and Equipment
We record property, plant and equipment at cost, inclusive of finance lease assets, with the adoption of ASC 842. We depreciate the cost of the majority of our property, plant and equipment using the straight-line method with depreciable lives ranging from 20 to 40 years for buildings and 3 to 15 years for machinery, equipment and fixtures. Finance lease asset amortization is recorded in depreciation expense. We expense normal maintenance and repair costs as incurred.
Impairment of Long-Lived Assets
Impairment of Long-Lived Assets
We review our long-lived assets for possible impairment whenever events or circumstances indicate that the carrying value of an asset or asset group may not be recoverable. We assess the recoverability of the carrying value of the long-lived assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. An impairment of a long-lived asset or asset group exists when the expected future pre-tax cash flows (undiscounted and without interest charges) estimated to be generated by the asset or asset group is less than its carrying value. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is measured based on the difference between the estimated fair value and carrying value of the asset or asset group. Assumptions and estimates used to estimate cash flows in the evaluation of impairment and the fair values used to determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying value of long-lived assets and could result in a future impairment charge.
Leases
Leases
We determine if an arrangement contains a lease in whole or in part at the inception of the contract. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. All leases greater than 12 months result in the recognition of a ROU asset and a liability at the lease commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide the information required to determine the implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. This rate is determined considering
factors such as the lease term, our credit standing and the economic environment of the location of the lease. We use the implicit rate when readily determinable.
Our lease terms include all non-cancelable periods and may include options to extend (or to not terminate) the lease when it is reasonably certain that we will exercise that option. Leases that have a term of 12 months or less at the commencement date are expensed on a straight-line basis over the lease term and do not result in the recognition of an asset or a liability.
Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense for finance leases is generally front-loaded as the finance lease ROU asset is depreciated on a straight-line basis, but interest expense on the liability is recognized utilizing the interest method that results in more expense during the early years of the lease. We have lease agreements with lease and non-lease components, primarily related to real estate, vehicle and information technology (“IT”) assets. For vehicle and real estate leases, we account for the lease and non-lease components as a single lease component. For IT leases, we allocate the payment between the lease and non-lease components based on the relative value of each component.
Goodwill
Goodwill
We have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform an annual quantitative goodwill impairment test. We have elected this option for our reporting unit. In addition, the carrying value of goodwill must be tested for impairment on an interim basis in certain circumstances where impairment may be indicated.
When we are required or opt to perform the quantitative impairment test, the fair value of our reporting unit is estimated with either the market approach or the income approach using a discounted cash flow model. Our income approach method uses a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate of return.
The discounted cash flow model requires us to make projections of revenue, gross margin, operating expenses, working capital investment and fixed asset additions for our reporting unit over a multi-year period. Additionally, management must estimate a weighted-average cost of capital, which reflects a market rate, for our reporting unit for use as a discount rate. The discounted cash flows are compared to the carrying value of the reporting unit and, if less than the carrying value, the difference is recorded as a goodwill impairment loss. In addition, we also perform a sensitivity analysis to determine how much our forecasts can fluctuate before the fair value of a reporting unit would be lower than its carrying amount.
We perform the required procedures as of the end of our fiscal third quarter.
Changes in our projections or estimates, a deterioration of our operating results and the related cash flow effect or a significant increase in the discount rate could decrease the estimated fair value of our reporting unit and result in a future impairment of goodwill.
Warranty
Warranty
We estimate and record a liability for standard warranty programs at the time our products are sold. Our estimates are based on historical experience and reflect management’s best estimates of expected costs at the time products are sold and subsequent adjustment to those expected costs when actual costs differ. As a result of the uncertainty surrounding the nature and frequency of product campaigns, the liability for such campaigns is recorded when we commit to a recall action or when a recall becomes probable and estimable, which generally occurs when it is announced. We review and assess the liability for these programs on a quarterly basis.
Research, Development and Engineering
Research, Development and Engineering
Our research, development and engineering programs are focused on product improvements, product extensions, innovations and cost reductions for our customers. Research, development and engineering expenditures include salaries, contractor fees, building costs, utilities, testing, technical IT, administrative
expenses and allocation of corporate costs and are expensed, net of contract reimbursements, when incurred.
Segment Information
Segment Information
We operate our business as one operating segment and also one reportable segment based on the manner in which we review and evaluate operating performance. The types of products from which revenue is derived are the same as those described in the description of the business section and the accounting policies are the same as those described in the summary of significant accounting policies.
The operating results are regularly reviewed by Atmus’ chief operating decision maker on a consolidated basis. The chief operating decision maker is our Chief Executive Officer. The chief operating decision maker assesses performance for our business and decides how to allocate resources based on net income that also is reported on the income statement as consolidated net income and is regularly provided with consolidated expense information from the income statement. The measurement of business assets is reported on the balance sheet as total consolidated assets.
The chief operating decision maker uses net income predominately in the annual budget and forecasting process. The chief operating decision maker considers budget-to-actual in deciding whether to reinvest profit into the operating segment or for other entity initiatives, such as acquisitions, paying dividends, or share repurchases. The chief operating decision maker also uses the profit or loss measure for determining compensation of certain employees.
Stock-Based Compensation
Stock-Based Compensation
We maintain a share-based compensation plan, which authorizes the granting of various equity-based incentives, including restricted stock units (“RSU”s) and performance share units (“PSU”s). Stock compensation expense is generally amortized on a straight line basis over the service period during which awards are expected to vest, generally three years.
RSUs are typically granted to selected employees on an annual basis and vest over three years. Dividend equivalents are paid during the vesting period. The fair value of our RSUs and other stock-based awards is measured at the market price of our Common Stock on the grant date.
PSUs vest based on varying performance, market and service conditions. The fair value of our PSUs is measured at the market price of our Common Stock on the grant date. The final award may equal 0-200 percent of the target grant, based on our actual performance during the vesting period.
Forfeitures are estimated on the grant date for all of our stock-based compensation awards.
Pension and other Postretirement Benefits
Pensions and other Postretirement Benefits
Atmus provides a range of benefits, including pensions, postretirement and post-employment benefits to eligible current and former employees, of which certain of our employees participate. For purposes of Atmus’ Consolidated Financial Statements, participation in Atmus plans are treated as single-employer plans. See Note 13, Pensions and Other Postretirement Benefits, for more information.
Recent Accounting Pronouncements
Recent Accounting Pronouncements
Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. We adopted this standard in the fourth quarter of 2024 and it did not have a material impact on our disclosures and no impacts to our results of operations, cash flows and financial condition.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, that requires entities to disclose additional information about federal, state, and foreign income taxes primarily related to the income tax rate reconciliation and income taxes paid. The new standard also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The guidance is effective for our fiscal year ending December 31, 2025, with early adoption permitted. The guidance does not affect recognition or measurement in our consolidated financial statements. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.
Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement
Expenses, which requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the consolidated financial statements. The guidance is effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The guidance is to be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. We are currently evaluating the potential impact of adopting this new guidance on our consolidated financial statements and related disclosures.
