"What happens after delisting
Trading moves to over-the-counter (OTC): Once a company is delisted, its shares can still be traded, but they move to the OTC market rather than a major exchange.
Challenges with OTC trading: Trading on the OTC market can be more difficult and less liquid than trading on a major exchange"
Not relevant to RSPI. Delisting refers to removal from an exchange (NYSE, NASDAQ). It's not the same as having a registration revoked.
