In connection with the Separation, the Company entered into a tax matters agreement with Cummins that, among other things, formalized our agreement related to the responsibility for historical tax positions for the period prior to the IPO for jurisdictions where our business was included in the consolidated or combined tax returns of Cummins.
Atmus’ effective tax rate for the three months ended March 31, 2025, was 21.3%. Atmus’ effective tax rate for the three months ended March 31, 2024, was 22.0%. The decrease in the effective tax rate was driven by a change in the mix of earnings among tax jurisdictions. The Company’s effective tax rate differs from the U.S. statutory rate primarily due to differences in rates applicable to foreign subsidiaries, withholding taxes and state income taxes.

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 was effective as of 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.
