Western Digital Corporation’s subsidiary SanDisk LLC (SanDisk) and certain of its subsidiaries, through their attorneys, have notified Toshiba Corporation (TOKYO:6502)(Toshiba) and Toshiba Memory Corporation (TMC), a wholly owned subsidiary of Toshiba, that they have initiated arbitration regarding TMC’s planned investments for additional BiCS capacity at TMC's Yokkaichi Operations, including at its Fab 6 building. Although Toshiba has not yet received a formal copy of the arbitration request, and is therefore not in a position to comment regarding its substance, Toshiba is disappointed by Western Digital’s initiation of additional arbitration at this important time for the parties’ collaboration.

As previously announced, production at Fab 6 will be entirely devoted to BiCS FLASHTM, Toshiba’s premiere 3D Flash memory product. Phase-1 of the fab is scheduled for completion in summer 2018, and will be a unilateral investment by Toshiba following SanDisk’s unwillingness to agree to reasonable commercial terms.
