INTERNAL ANNOUNCEMENT

Cummins launches exchange offer for separation of Atmus

Atmus colleagues,

Today, Cummins Inc. (“Cummins”) launched an exchange offer to split-off its remaining 80.5% stake in Atmus Filtration Technologies Inc. (“Atmus”).

Through this exchange offer, Cummins shareholders can choose to exchange all, some or none of their shares of Cummins stock for shares of Atmus common stock, subject to the terms of the exchange offer. If the exchange offer (including all related transactions) is consummated, referred to as the “final separation”, Cummins will no longer be the controlling shareholder of Atmus, and Atmus will operate as a separate and fully independent company.

As an Atmus employee, if you hold any shares of Cummins common stock, this exchange offer may be relevant to you and the stock you hold. Information regarding the effect of the exchange offer on the Cummins Retirement and Savings Plan and the Cummins Retirement and Savings Plan for Certain Collectively Bargained Employees (together, the “RSP”), your stock and voluntary participation in the exchange offer, as well as who to contact for more information, is available on the RSP website at yourbenefitsresources.com/cummins. For further assistance, please connect with a 401(k) representative.

This exchange offer marks an important step towards Atmus’ final separation from Cummins and for our future as a global leader in filtration and media solutions. Today I ask for your continued focus on delivering your objectives and in upholding ‘The Atmus Way’ as we look to operate as a fully independent company. I would like to thank each of you for all that you do to contribute to the success of Atmus and in creating a better future by protecting what is important.

We are Atmus.

Steph Disher 

President and Chief Executive Officer
