We didn't 'fall' from 50 cents. Thompson shot his own company in the gut and it bled out. There is a big difference.
The wound hasn't healed even today. KBLB is still bleeding. That's why good news can be released with no significant increase in share price.
Adding insult to injury, Thompson bungled the 2019/2020 rollout in Vietnam, setting his company back by at least a year. At the moment, investors don't really understand what is going on with the company. Will there be a big announcement about a significant delivery? Will we wake up to a 100-to-1 reverse split? Will we get bad news on the production front?
One thing is for certain: we won't wake up to an uplist. Not in the forseeable future, at least. That saves Thompson from having to forgive his debt to the company.
