Lo del delisting es un proceso lento, que se puede ver interrumpido en cualquier momento: tiene que estar 30 días seguidos por debajo de $1 para activarse el procedimiento, y luego le dan un período de 180 días para regularizar (sirve 10 días seguidos por encima de $1 en ese período)... y si no lo consigue, siempre queda la opción del R/S.
The most common reasons for a deficiency notice are a share price that falls below $1.00 or a market cap that falls below the stated minimum (as low as $5 million if other requirements are satisfied). If a company is in violation of the continued listing standards for a period of 30 consecutive days, the NASDAQ sends a "deficiency notice."
Once a deficiency notice has been sent, the company has 90 days to comply with the continued listing standards, or 180 days if the violation was for a sub-$1.00 share price. In order to be compliant, the company's share price or market cap must rise above the minimum for at least 10 consecutive days in the 90-day (or 180-day) period.
