"The Atmus team delivered strong financial results while simultaneously integrating Koch Filter to unlock growth for our Industrial Solutions business segment," said Steph Disher, Chief Executive Officer of Atmus. "I continue to be inspired by our people's ability to navigate uncertain markets and execute our four-pillar growth strategy to deliver long-term shareholder value."

First Quarter Results

For the first quarter of 2026, Atmus posted net sales of $478 million, compared to $417 million in the first quarter of 2025, an increase of 14.6%. The increase in sales was primarily driven by the acquisition of Koch Filter, the favorable impacts of currency and increases in pricing, partially offset by lower volumes.

Gross margin was $137 million, compared to $111 million in the first quarter of 2025. Gross margin as a percent of net sales was 28.6% compared to 26.5% in the same period last year. The increase in Gross margin was primarily due to incremental margin from the acquisition of Koch Filter, increases in pricing, lower one-time costs associated with the separation of the business from Cummins Inc. and favorable impacts of currency, partially offset by higher logistics and duties costs, lower volumes and other manufacturing costs.

Adjusted EBITDA was $95 million, compared to $82 million in the first quarter of 2025. Adjusted EBITDA margin was 19.8% compared to 19.6% in the same period last year. Adjusted EBITDA in the first quarter of 2026 excludes $6 million of acquisition costs and $1 million of one-time integration costs associated with the acquisition of Koch Filter compared to the prior year quarter which excludes $9 million of one-time costs associated with the separation of the business from Cummins.

Net income was $48 million, or $0.59 of diluted earnings per share in the first quarter of 2026, compared to $45 million, or $0.54 of diluted earnings per share in the same period last year.

Adjusted earnings per share was $0.69 in the first quarter of 2026, compared to $0.63 of Adjusted earnings per share in the same period last year.

The effective tax rate for the first quarter of 2026 was 20.9% compared to 21.3% for the same period last year.

Cash provided by operating activities was $38 million in the first quarter of 2026, compared to cash provided by operating activities of $29 million in the first quarter of 2025.

Adjusted free cash flow was $33 million in the first quarter of 2026, compared to $20 million in the first quarter of 2025. Adjusted free cash flow in the first quarter of 2026 excludes $6 million of acquisition costs and $1 million of one-time integration costs associated with the acquisition of Koch Filter. The first quarter of 2025 excludes $4 million of one-time adjustments associated with the separation of the business from Cummins.

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 and in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2026.

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, transaction costs associated with the Koch Filter acquisition and costs related to the integration of Koch Filter 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 they allow 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 costs associated with the acquisition and integration of Koch Filter.

• "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, transaction costs associated with the Koch Filter acquisition, costs related to the integration of Koch Filter and amortization of the intangible assets acquired in the Koch Filter acquisition less the related tax impact of the same one-time expenses, acquisition and integration costs and amortization expense. 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 items associated with becoming a standalone public company, transaction costs associated with the Koch Filter acquisition and costs related to the integration of Koch Filter. 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.
