With the approval of the DoD, the Shareholder (Hitachi Vantara) may remove a Proxy Holder (Board Member) for acts in violation of the Agreement (Proxy Agreement), including the inability to protect the legitimate economic interest of the Shareholder (Hitachi Vantara), and/or gross negligence. It's not a hard sell to show the government that the failures of the CEO David Stuart Turner and crew have negatively impacted the business = not protected the legitimate economic interest of the Shareholder (Hitachi Vantara).
All Hitachi Vantara has to do is apply pressure and the Board will bend, if not break. The prior HVF President was shown the door by the current Board members for far less and he was actually liked. David Turner has achieved record setting level failures, amassed non stop litigation against the company, created a toxic work environment pushing HVF off a cliff into what seems to be an unrecoverable death spiral.
The only way to stop the hemorrhage is to remove Dave Turner, remove/replace the inept Board that enabled this disaster to continue when all the signs were there and bring in a new leadership team to address the toxic environment this group has caused.
