No, it is not tough to do ... and I doubt that more than a very small percentage of shareholders have their accounts listed as OBO. The company has literally had months to work on this and formulate a plan, Obviously, they haven't done so.
As I said earlier, the company has had months to prepare for this. If there was any intention of acting in the interest of shareholders, they would have at least prepared an explanation of their plan and distributed it to known shareholders.
While the company is now private, the transition to the new status is a work in progress. An immediate priority is to identify all current shareholders and their actual shareholding at the time that the SEC issued final revocation. This is actually tougher and more time-consuming than it sounds as many shareholders do not have their accounts classified as 'NOBO'
