Not sure. If we go with it like Royal Dutch Shell's dual-listing structure for example, then the shares on the LSE is not inter-changeable with the NYSE, meaning WFE shares on the LSE will not be able to be traded for ASX-listed shares. Both will be traded separately.
IF that is the case, and I hope I'm not mistaken, then it means ASX holders will still be in suspension whilst our LSE counterparts may be popping champagne bottles, assuming ASX has further delays or requests (so-called goalpost shifting) for WFE's re-compliance and re-listing.
Or perhaps, they can time the dual-listing to occur concurrently with the ASX re-listing? Maybe that will be best.
