Western Digital’s SanDisk Subsidiaries Initiate New Arbitration Proceedings Against Toshiba in the ICC International Court of Arbitration

San Jose, Ca - September 20, 2017

Toshiba's Decision to Unilaterally Invest in Manufacturing Equipment at Fab 6 Operations Constitutes a Breach of the JV Agreement

Terms of the JV Agreement are Clear; SanDisk has the Right to Jointly Invest in Expansions and Conversions of BiCS Manufacturing Capacity

Western Digital Corp. (NASDAQ: WDC) today announced that several of its SanDisk subsidiaries have filed an additional Request for Arbitration with the ICC International Court of Arbitration related to three NAND flash-memory joint ventures ("JVs") operated with Toshiba Corporation ("Toshiba").

On Aug 3, 2017, Toshiba announced that it would unilaterally invest in manufacturing equipment for the Fab 6 clean room at the JV operations in Yokkaichi, Japan. The arbitration demand seeks, among other things, a permanent injunction preventing Toshiba from making unilateral investments in manufacturing equipment for Fab 6 without first giving SanDisk the opportunity to make a comparable investment in expansions and conversions of JV capacity for BiCS 3D NAND flash memory.

Western Digital commented: 

  • It is unfortunate that SanDisk is forced to initiate binding arbitration to remedy Toshiba's retaliatory breach of the JV agreement entered into by both SanDisk and Toshiba.

  • The terms of the agreement and our related legal rights are clear. The agreement gives SanDisk the right to participate in expansions and conversions of manufacturing capacity for BiCS 3D NAND flash memory products through joint investments in Fab 6 equipment. Toshiba has improperly denied SanDisk its rights to joint investment by unilaterally investing in manufacturing equipment at Fab 6.

  • We believe that our NAND supply requirements through calendar 2018 are secure, with no meaningful supply from Fab 6 anticipated until calendar year 2019.

  • We will continue to act in the best interests of our stakeholders, protecting SanDisk's interests in the JVs and consent rights through both our request for injunctive relief and the arbitration process.

The arbitration requests filed by Western Digital's SanDisk subsidiaries on May 14, 2017, and July 5, 2017, continue to move forward in the ICC International Court of Arbitration.
