According to the SEC filing the RS is 15000:1. In theory the shareholder should hold as much value after the RS as before. I have never had that experience. One startup I was unfortunate to hold went through TWO RS. My 10M shares became five shares. IMO, the purpose of a RS is to wipe out current/old shareholders so they can start from a clean slate. In most cases the PPS sinks back to nothing immediately after the RS, then the company dies, becomes a shell.
We should learn of the date of the RS for ENTI before it happens. Your best strategy is to watch the bid and try and unload before the RS, even if it might be a loss, because you'll loose even more after the RS. If I can't unload my shares before the RS, this will likely be a total loss for me. Even if the pps went to a $1 I would only recover a small fraction of my original investment.
