Fourth Quarter Results

For the fourth quarter of 2025, Atmus posted net sales of $447 million, compared to $407 million in the fourth quarter of 2024, an increase of 9.8%. The increase in sales was primarily driven by increases in pricing, higher volumes and the favorable impacts of currency.

Forward-looking statements may be identified by the use of words such as “anticipates,” “expects,” “forecasts,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “could,” “should,” “may” or words of similar meaning. All statements other than statements of historical fact are forward-looking statements, including, without limitation, statements regarding the outlook for our future business and financial performance, discussions of future operations, our strategy for growth and market position. These statements are not guarantees of future performance and involve certain risks, uncertainties

and assumptions, which are difficult to predict. If the underlying assumptions prove inaccurate, or known or unknown risks or uncertainties materialize, our actual outcomes, results and financial condition may differ materially from what is expressed, implied or forecasted in such forward-looking statements. Risks and uncertainties include, but are not limited to, those reflected in Part I, Item 1A, “Risk Factors,” and elsewhere in our Annual Report on Form 10-K for our fiscal year ended December 31, 2025 and also as may be described from time to time in future reports we file with the Securities and Exchange Commission (SEC). You are cautioned not to place undue reliance on forward-looking statements. The forward-looking statements made herein are made only as of the date hereof and we undertake no obligation to publicly update or to revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

Non-GAAP measures

We use non-GAAP financial information and believe it is useful to investors as it provides additional information to facilitate comparisons of historical operating results, identify trends in our underlying operating results and provide additional insight and transparency on how we evaluate our business. We use non-GAAP financial measures to budget, make operating and strategic decisions and evaluate our performance. We have detailed the non-GAAP adjustments that we make in our non-GAAP definitions below. We believe the non-GAAP measures should always be considered along with the related U.S. GAAP financial measures. We have provided the reconciliations between the U.S. GAAP and non-GAAP financial measures and we also discuss our underlying U.S. GAAP results throughout our Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for our fiscal year ended December 31, 2025.

Our primary non-GAAP financial measures are listed below and reflect how we evaluate our current and prior-year operating results. As new events or circumstances arise, these definitions could change. When our definitions change, we provide the updated definitions and present the related non-GAAP historical results on a comparable basis.

•“EBITDA” is defined as earnings or losses before interest expense, income taxes, depreciation and amortization and “EBITDA margin” is defined as EBITDA as a percent of net sales. We believe EBITDA and EBITDA margin are useful measures of our operating performance as they assist investors and debt holders in comparing our performance on a consistent basis without regard to financing methods, capital structure, income taxes or depreciation and amortization methods, which can vary significantly depending upon many factors. Additionally, we believe these metrics are widely used by investors, securities analysts, ratings agencies and others in our industry in evaluating performance.

•“Adjusted EBITDA” is defined as EBITDA after adding back certain one-time expenses, reflected in cost of sales and selling, general and administrative expenses, associated with becoming a standalone public company, one-time restructuring and long-lived asset impairment charges and “Adjusted EBITDA margin” is defined as Adjusted EBITDA as a percent of net sales. We believe Adjusted EBITDA and Adjusted EBITDA margin are useful measures of our operating performance as it allows investors and debt holders to compare our performance on a consistent basis without regard to one-time costs attributable to our becoming a standalone public company and non-recurring long-lived asset impairment charges.

•“Adjusted earnings per share” is defined as diluted earnings per share (the most comparable U.S. GAAP financial measure) after adding back certain one-time expenses, reflected in cost of sales and selling, general and administrative expenses, associated with becoming a standalone public company, one-time restructuring costs and long-lived asset impairment charges less the related tax impact of the same one-time expenses and asset impairment

charges. We believe Adjusted earnings per share provides improved comparability of underlying operating results.

•“Free cash flow” is defined as cash flows provided by (used for) operating activities less capital expenditures and “Adjusted free cash flow” is defined as Free cash flow after adding back certain one-time capital expenditures and other separation related costs associated with becoming a standalone public company and one-time restructuring costs. We believe Free cash flow and Adjusted free cash flow are useful metrics used by management and investors to analyze our ability to service and repay debt and return value to shareholders.

The metrics defined above are not in accordance with, or alternatives for, U.S. GAAP financial measures and may not be consistent with measures used by other companies. It should be considered supplemental data; however, the amounts included in the EBITDA, EBITDA margin, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted earnings per share, Free cash flow and Adjusted free cash flow calculations are derived from amounts included in the consolidated statements of net income and cash flows.

We do not consider our non-GAAP financial measures as superior to, or a substitute for, the equivalent measures calculated and presented in accordance with GAAP. Some of the limitations are: such measures do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments; such measures do not reflect changes in, or cash requirements for, our working capital needs; such measures do not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our debt; although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and such measures do not reflect any cash requirements for such replacements; and other companies in our industry may calculate such measures differently than we do, limiting their usefulness as comparative measures. To properly and prudently evaluate our business, we encourage you to review the unaudited condensed consolidated financial statements included in our SEC filings and not rely on a single financial measure to evaluate our business.
