AmirD12: to your question it is best to read the BK PLAN by Nuvectra Corp. to see if shareholders can buy warrants of the reorganized company's new stock issue, if there will be any new stock (equity) issue.
As it stands right now all previous share equity was cancelled so those shares no longer exist.
It is unfortunate that most shareholders of Chapter 11 companies that reorganize are last in line to receive any dispensation because secured creditors come first, unsecured creditors come second, preferred share holders come third, and common share holders come last, often losing the entirety of their share equity investment.
