I think short term impact will be huge fallout as everyone jumps ship, but I think they are legit and over time will recover.
What happens when the SEC suspends trading or FINRA halts trading in a security?
When a security is suspended or halted, OTC Markets Group removes all quotes from the system and displays a "Halted/Suspended" message.
SEC suspensions for OTCQX, OTCQB and Pink securities have a duration of 10 business days. After the suspension ends, broker-dealers may re-enter their quotes if they comply with Rule 15c2-11. This rule requires the filing, with FINRA, of a new Form 211 which must include the company’s current financial information.
