My guess is months. Just my opinion. Others think it could be sooner.
A company pushed down to the Expert Market would be able to apply for relisting on OTC Markets Group once a market maker has filed a new Form 211 with FINRA, and the company has made current public information available. This requires a company to locate a market maker to file a Form 211 on its behalf and, once the form is filed, there is no set timeframe for a re-application approval. When compliance with the amended rule is demonstrated, relisting can occur.
