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 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.
