Ann: Suspension from Official Quotation, page-61

Massive? It wasn’t there. A price and volume query can be instigated by ASX at anytime. Only imo, the prospectus Nasdaq was leaked and contains price sensitive information that was not provided to ASX and Shareholders previously. For example, a revenue statement within that was not previously announced.
Clearly this is not a price query halt alone, it come with questions to AHI, read section 8 ASX.

AHI may have dumped that prospectus too early, something they ASX did not like and hence TH.

Volume and price queries regularly come with something dumped on ASX at close, this one was obviously very sensitive and they halted us immediately. IMO nothing to do with price or volume, moreso compliance and the read of an IPO that maybe out there.

Soon find out, my $1 each way suggests ASX are questioning disclosure.
