SEC suspensions are temporary. The suspended ticker has 10 days to become current.
No, it doesn't work that way. If a company is suspended for delinquency, and an action to revoke registration is initiated, there's no recourse. Registration will be revoked. If the company wants, it can submit a new registration statement once it's got those financials ready.
You said what happened with Avant. It said it had its financials ready to file. The SEC revoked registration anyway.
