I don't understand that either - it really does not add up. Either I'm looking at stale information or I'm missing the plot.

I do have access to a Bloomberg terminal and so might just have a look (later) on it to see if there is updated information on the top 20 shareholders there.

This list is for options expiring in 3 years, so part of the entitlement offering - understandably exisiting top 20 holders have not put in more funds (they've been there since the IPO) and would have lost a fair bit (unrealised). With the exception of a few who seemed to have participated again and a few new names - including a few aesthetic surgeons and 2/3 funds.

That being said if they got alloted that many options, technically the entitlement offer should have been oversubscribed - scratching my head on this one tbh.
