I would anticipate one if they want to stay on the current exchange.
Since they are on a major exchange, they may have to perform a R/S in order to meet a minimum requirement for the stock price. I believe that the minimum price to be $1 for NYSE. Relying on news to push the price over $1 and stay over is difficult to do.
The exchange will send a warning to them stating that they are no longer in compliance, and they have a certain amount of time to comply (usually 6 months). Otherwise, their stock will be delisted and demoted to OTC.
