Also per the following link "If a company closes below a $1/share bid price for 30 consecutive days, the Nasdaq sends the company a written notice. The notice states that the company is no longer in compliance with its continued listing requirements and has 180 days to regain compliance. Otherwise, the company will face delisting."

Not mentioned above, is that after 180 days, the company can ask for another 180 days extension, that is usually granted. So, practically, the company have over a year before worrying about being delisted if the share price falls below $1 and does not recover above it.
