MKS Inc. completed a private offering of €1.0 billion senior notes due 2034 at a 4.250% interest rate to refinance existing debt. The company used the net proceeds, along with cash on hand, to prepay approximately $1.3 billion of its $2.2 billion senior secured U.S. dollar tranche B term loan.
On the same date, MKS entered into a Sixth Amendment to its Credit Agreement, replacing the prepaid term loan with a new $914 million U.S. dollar tranche B term loan and refinancing its €587 million euro tranche B term loan and revolving credit facility. The revolving facility was increased to $1.0 billion, loan margins were reduced across term loans and revolver, and maturities for the term loans and revolver were extended.
MKS Inc. plans a private Offering of €1.0 billion aggregate principal amount of senior notes due 2034. The company expects net proceeds of about €985 million after purchaser discounts and expenses. It intends to combine these funds with other refinancing proceeds and cash to prepay approximately $1.3 billion of, and refinance in full, its $2.2 billion U.S. dollar tranche B term loan and to refinance in full its €587 million euro tranche B term loan. The Offering is expected to close on February 4, 2026, subject to customary conditions, and is not contingent on completion of the term loan refinancing.
MKS Inc. updated its outlook for the quarter ended December 31, 2025 while discussing potential debt refinancing with lenders. The company now expects revenue of approximately $1,030 million, plus or minus $5 million, GAAP net income of $106 million, plus or minus $3 million, and Adjusted EBITDA of $248 million, plus or minus $2 million. The midpoint of revenue guidance increased by $40 million, mainly from higher demand across all markets and divisions, with higher gross margin partly offset by increased operating expenses, including higher variable compensation and restructuring charges.
MKS also outlined a planned refinancing that would use proceeds from up to approximately €1.0 billion of contemplated new euro-denominated unsecured indebtedness, a new approximately $0.9 billion term loan due 2033, and cash on hand to refinance its existing $2.2 billion term loan and replace its existing €0.6 billion term loan with a new €0.6 billion term loan due 2033. In addition, it expects commitments to increase its revolving credit facility from $675 million to $1 billion and extend its maturity to 2031. The transactions are expected to be leverage neutral, extend debt maturities and reduce interest expense, but remain subject to market and other conditions and may not be completed as contemplated.
