Western Digital Corporation (NASDAQ: WDC) ("Western Digital" or the "Company") today announced the closing of its underwritten public offering of (i) $500,000,000 aggregate principal amount of 2.850% senior unsecured notes due 2029 and (ii) $500,000,000 aggregate principal amount of 3.100% senior unsecured notes due 2032. The net proceeds of the offering were approximately $988 million, after deducting underwriting discounts and commissions and other estimated offering expenses.

"We are pleased to have achieved this milestone of receiving the second investment grade corporate rating and closing of the unsecured notes", said Bob Eulau, Western Digital's CFO. "Our strong cash flow generation, and our commitment to paying down debt have enabled Western Digital to delever our balance sheet. As we approach our targeted debt levels, we look forward to re-evaluating our capital return and capital allocation priorities."
