Not worried about NASDAQ maintenance requirements. $4 is the threshold requirement for NASDAQ listing initially. Once listed there are different requirements to maintain. If a NASDAQ listed stock closes below $1 for 30 consecutive trading days a notice of non-compliance is issued, and the company has 180 days to regain compliance. A listed company can regain compliance by having a closing Bid price of $1 or better for 10 consecutive business/trading days. Not worried in the slightest.
