It would make sense to re-list on the ASX because of the familiarity the Board has with it. Perhaps consolidate, THEN if the circumstance dictate, re-list or dual-list with somewhere else.
This is exactly what happened with Avita Medical (ASX: AVH) which I also hold.
Far too early to dream or speculate though.
