I'm not really all that familiar with the company, I bought back during the IPO in 2017, and did some DD back then, but sold on the initial run from something like .60 to $6.00, if I remember correctly. I've loosely followed it since then, but not that closely.
From what I can tell, it looks like private company now. They filed Chapter 11, and did not liquidate. I'd assume they could be acquired by another, public company, and go essentially go public again as a subsidiary, assuming it was approved by the Bankruptcy Court.....but I'm not 100% sure.
