REDG hasn't been current, on SEC filings, for about three years.
Benny has been saying that he has been working (with a team) to get current on SEC filings since late 2015 early 2016. Now, I doubt he was working towards it, as the company couldn't pay for it.
But, I think , if he were working towards current filing (and had documentation) REDG would have been granted an additional extension, for a good faith effort, to get current and not be suspended/delisiting.
I, also, believe that if Benny/REDG could be current today (magically), the SEC would revoke the suspension/delisting and allow the stock to trade. In the absence of illegal activity, the SEC isn't going to stop a company permanently for missing technical deadlines.
