ANDOVER, Mass., Jan. 26, 2026 (GLOBE NEWSWIRE) -- MKS Inc. (NASDAQ: MKSI) (“MKS”) today announced that it intends to offer €1.0 billion aggregate principal amount of senior notes due 2034 (the “notes”) in a private offering (the “offering”). The offering is subject to market and other conditions, and there can be no assurance as to whether, when or on what terms the offering may be completed.

The notes will be unsecured, senior obligations of MKS, and will be guaranteed on a senior unsecured basis by certain subsidiaries of MKS. MKS intends to use the net proceeds from the offering, together with the net proceeds from the previously announced partial refinancing of its existing $2.2 billion U.S. dollar tranche B term loan (the “USD Tranche B Term Loan”), the net proceeds from the previously announced refinancing of its existing €587 million euro tranche B term loan (the “Euro Tranche B Term Loan” and together with the USD Tranche B Term Loan, the “Term Loan Facility”) and cash on hand, to (i) prepay approximately $1.3 billion of, and refinance in full, the USD Tranche B Term Loan, and (ii) refinance in full the Euro Tranche B Term Loan.

The notes will be offered and sold to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) and to non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act. The offer and sale of the notes have not been and will not be registered under the Securities Act or any state securities laws and such securities may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws. Any offer of the notes will be made only by means of a private offering memorandum.

This press release shall not constitute an offer to sell, or a solicitation of an offer to buy, nor shall there be any sale of, any securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful under the securities laws of any such state or jurisdiction.
