WilmerHale represented MKS Inc. (NASDAQ: MKSI) (“MKS”) in its offering of €1.0 billion aggregate principal amount of 4.250% senior notes due 2034. WilmerHale also represented MKS in connection with a successful refinancing of its existing $2.2 billion US dollar tranche B term loan, €587 million euro tranche B term loan and $675 million revolving credit facility with a new $914 million US dollar tranche B term loan, €587 million euro tranche B term loan and $1.0 billion revolving credit facility, which, among other changes, (i) increased the commitments under the revolving credit facility, (ii) extended the maturity of the term loans to February 4, 2033 and the revolving credit facility to February 4, 2031 and (iii) reduced the interest rates for the term loans and the revolving credit facility. MKS used the net proceeds from the offering, together with cash on hand, to prepay approximately $1.3 billion of its US dollar tranche B term loan. The combined actions diversify MKS’ capital structure, replace a portion of its secured debt with unsecured debt, extend its debt maturities and reduce its interest expense.
