Western Digital‘s (NASDAQ: WDC) lengthy battle over Toshiba‘s (NASDAQOTH: TOSBF) memory unit seemingly ended on Sep. 20, with Toshiba’s board voting to sell the business to a consortium led by SK Hynix and Bain Capital for about $18 billion. Western Digital stated that it was “disappointed” in Toshiba’s decision, and insisted that it violated contractual agreements with its subsidiary SanDisk.
