Cummins announces plans for full separation of Atmus Filtration Technologies Inc. through an exchange offer

Today, Cummins Inc. (“Cummins”) announced plans to fully split off its remaining interest in Atmus Filtration Technologies Inc. (“Atmus”) and offer to exchange shares of Cummins common stock for shares of Atmus common stock that it owns. In May 2023, Atmus completed its initial public offering, and afterwards Cummins retained the remaining 80.5% interest in Atmus and remained Atmus' largest shareholder.

If you hold Cummins common stock during the exchange offer period, you have the opportunity to exchange shares of Cummins common stock for shares of Atmus common stock, if desired, subject to the terms of the exchange offer. This includes if you hold Cummins common stock through an official Cummins stock program, such as the Employee Stock Purchase Program (ESPP) or long-term grants, or through one of the Cummins stock funds in the Cummins Retirement and Savings Plan (RSP). If you participate in one of these programs, information about the exchange offer and how to make an election will be sent to you directly from each plan provider.

If you hold Cummins common stock outside of an official Cummins stock program or RSP, such as in a brokerage account or other investment account, you have the option to participate in the exchange offer. If you do not wish to participate, no action is required. Please reach out to your broker or other provider (such as TD Ameritrade, Charles Schwab, etc.) for more information.

The above does not account for all instances by which you may hold Cummins common stock. All Cummins shareholders eligible to participate in the exchange offer will receive additional information about the exchange offer.

Please read all information that you receive about the exchange offer and consult with your bank, broker, investment, legal, tax or other advisors to understand your choices and make the right decision for you.

Please note that participation is voluntary. If you elect to participate, you must do so by the established deadlines, which are in mid-March and will be different for the Cummins stock programs, RSP, and Cummins common stock you may own through direct brokerage. To better understand your options, carefully review the information sent to you by each plan/brokerage and the available online resources below.

If you choose not to participate in the exchange offer, no further action is needed from you.
