Rhea-AI Filing Summary

Atmus Filtration Technologies Inc. entered into a definitive agreement for its subsidiary Cummins Filtration Inc. to acquire all outstanding shares of Koch Filter Corporation from Air Distribution Technologies, Inc. for $450 million, subject to purchase price adjustments. At closing, the buyer will place $1,450,000 in escrow to cover customary post-closing adjustments for cash, debt, working capital, and transaction expenses.

The deal is subject to typical conditions, including expiration or termination of the Hart-Scott-Rodino waiting period, no governmental order blocking the transaction, accuracy of key representations and warranties, compliance with covenants, and no material adverse effect. Either party may terminate if the transaction has not closed by March 31, 2026, with a possible 30‑day extension, and each may seek specific performance in certain cases. Atmus expects to fund the purchase with cash on hand and borrowings under its credit facility and currently expects the transaction to close in the first quarter of 2026.

Insights

Atmus plans a $450M Koch Filter acquisition funded with cash and credit.

Atmus Filtration Technologies has signed a stock purchase agreement for its subsidiary to buy Koch Filter Corporation from Air Distribution Technologies for $450,000,000, subject to customary adjustments. A separate escrow of $1,450,000 will cover final true‑ups for cash, indebtedness, net working capital, and transaction expenses, which is a standard risk-sharing feature in such deals.

Closing depends on conditions such as expiration or termination of the Hart‑Scott‑Rodino waiting period, no blocking governmental orders, accuracy of specified representations within materiality thresholds, compliance with covenants, and absence of a continuing material adverse effect since signing. The agreement caps regulatory commitments by not requiring either party to litigate or divest assets to obtain approvals, which could limit flexibility if regulators raise concerns.

The outside date is March 31, 2026, extendable by 30 days if only regulatory approvals remain, and in certain circumstances either party can seek specific performance to force closing. Atmus expects to use cash on hand and borrowings under its credit facility, potentially upsized, to fund the deal, indicating incremental leverage but without detailed metrics in this excerpt. The company currently expects closing in the first quarter of 2026, though this depends on the regulatory timeline and satisfaction of the stated conditions.

Item 1.01 Entry into a Material Definitive Agreement.

 

On November 21, 2025, Atmus Filtration Technologies Inc., a Delaware corporation (the “Registrant,” “we,” “us” or “our”), entered into a stock purchase agreement (the “Purchase Agreement”) with Cummins Filtration Inc., an Indiana corporation and a wholly-owned subsidiary of the Registrant (the “Buyer”), and Air Distribution Technologies, Inc., a Delaware corporation (the “Seller”), pursuant to which the Buyer agreed to purchase all of the issued and outstanding shares of Koch Filter Corporation, a Kentucky corporation and wholly owned subsidiary of the Seller (“Koch”), in exchange for $450 million, subject to certain adjustments as set forth in the Purchase Agreement (together with the other transactions contemplated thereby, the “Transaction”). The Registrant agreed to guarantee the due, complete, and punctual payment of, as well as the observance, performance and discharge of all of the Buyer’s obligations under, the Purchase Agreement, all on customary terms and conditions.

 

The Purchase Agreement provides that at the closing of the Transaction, the Buyer will deposit, or cause to be deposited, $1,450,000 with an escrow agent to be held pending finalization of customary purchase price adjustments regarding cash, indebtedness, net working capital and transaction expenses, contained in the Purchase Agreement.

 

The closing of the Transaction is subject to customary closing conditions, including, among others: (a) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”); (b) the absence of any order by a governmental authority preventing the consummation of the Transaction; (c) in the case of the Seller’s and the Buyer’s obligations to complete the transaction, the accuracy of certain representations and warranties contained in the Purchase Agreement subject to customary materiality standards; (d) material compliance by the Buyer and the Seller with certain pre-closing covenants; and (e) the absence of any continuing material adverse effect since the date of the Purchase Agreement.

 

Under the Purchase Agreement, the Buyer and the Seller have made customary representations and warranties and have agreed to be bound to customary covenants for transactions of this type. Furthermore, the Buyer and the Seller are required to use reasonable best efforts to obtain necessary approvals under the HSR Act; provided, that neither the Buyer nor the Seller shall be required to defend or commence any litigation or sell, divest or hold separate any businesses, products, rights, services, licenses, or assets.

 

The Purchase Agreement contains certain customary termination rights, including that either party may terminate the Purchase Agreement if, subject to certain exceptions and limitations, the Transaction has not closed by March 31, 2026 (the “Outside Date”), subject to an additional thirty (30) days, which extended date shall thereafter be considered the Outside Date, if, on such date, all of the closing conditions except those relating to regulatory approvals have been satisfied or waived. The Purchase Agreement also provides that, in certain circumstances, each party to the Purchase Agreement may seek to compel the other party to specifically perform its obligations under the Purchase Agreement.

 

We expect to use cash on hand and borrowings under our credit facility, including a potential upsize, to fund the Transaction. Subject to the satisfaction or waiver of customary closing conditions, the Transaction is expected to close in the first quarter of 2026.

 

The above summary of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Purchase Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
