Hbpainter, they were just not compliant and never delisted, we delisted to OTC. The company never stayed under $1 during a given period set by Nasdaq, they were able to get above $1 for ten days to get back in good grace.
In the case you are looking at the company had not been delisted. Listed companies just have to keep their price over $1. If they fall under, they have 6 months or so to get back over. That is what happened.
Once a company has been delisted, to get back on it is a new listing. That requires $4 for 90 days (in general).
They have not been delisted for years. They have been in a warning period and my guess is that because of the pandemic even the periods listed in this notice were further tolled again until now.
