BRLIU is available on T212 so I can’t see this as a reason for potentially not listing PSTH when it IPOs. I asked about SPAC Warrants a while ago which is perhaps where you read it @adm?
BRLIU: “Each unit consists of one ordinary share, no par value per share (“Ordinary Share”), one right, with each right entitling the holder to 1/10 of one Ordinary Share, and one warrant, with each warrant entitling the holder to purchase one Ordinary Share at a price of $11.50 per share.”
