Western Digital Announces Closing of Amendment, Extension and Increase of Term A Loans and Revolving Facility, Credit Agreement Amendments and Debt Repayment

Western Digital Corporation (NASDAQ: WDC) ("Western Digital" or the "company") today announced that it obtained a new $5.022 billion Term Loan A-1 facility maturing in 2023, reflecting a $1.0 billion increase over its previous term loan A facility and an extension of the maturity date by approximately two years. Loans under the Term Loan A-1 facility bear interest at a rate of LIBOR plus an applicable margin depending on the corporate family ratings of Western Digital, with an initial interest rate of LIBOR + 1.50%. The proceeds of the new Term Loan A-1 loans were used to settle Western Digital's existing $4.022 billion Term Loan A maturing in 2021 and, together with available cash on hand and the proceeds of its 1.50% convertible senior notes due 2024, to redeem its outstanding 7.375% senior secured notes due 2023 in full and to, among other things, pay fees and expenses related to the foregoing and the other refinancing transactions. In addition, Western Digital has obtained amendments to its senior credit facilities to, among other things, provide for more covenant flexibility and a release of the security and guarantees (along with additional covenant flexibility and incremental capacity) subject to compliance with certain conditions, including achieving a corporate family rating of at least Ba1/BB+/BB+ from at least two of S&P, Moody's and Fitch and the repayment of any outstanding term B loans, with a reinstatement if the corporate family rating falls below Ba2/BB/BB from at least two of S&P, Moody's and Fitch.

Western Digital also successfully obtained commitments for a $2.25 billion revolving credit facility maturing 2023, reflecting a $750 million increase in the size of its revolver and an extension of the maturity date by approximately two years.  The new revolving credit facility replaced Western Digital's existing $1.5 billion revolving credit facility maturing in 2021.  Loans under the new revolving credit facility bear interest at a rate of LIBOR plus an applicable margin depending on the corporate family ratings of Western Digital, with an initial rate of LIBOR + 1.50%.  Western Digital borrowed $500 million under the new revolving credit facility to fund a voluntary prepayment of its USD term B-3 loans.
