Remember AHI listed its ADS on the NASDAQ back in November.
AHI opened with it's IPO on the NASDAQ on Friday the 19th of November. ( 01:30am Sat am our time )
A check back on the ASX announcements shows a Trading Halt was called on ASX for Thursday the 18th (our time)
So it was closed for trading Thursday the 18th and didn't re-open until Wednesday the 24th whilst it remained in voluntary suspension whilst it dealt with the issue of over-allotments.
The IHL BOD may handle the ASX process differently, may be!
Because in the NASDAQ update dated 17th December
https://stocknessmonster.com/announcements/ihl.asx-3A584039/Clearly states that IHL will continue to trade throughout the Offering and upon completion of the offering, now whether that includes a trading halt or excludes a trading halt, I am not sure. Someone out there may have a better clue on this than myself.
In the interim be prepared for a possible Trading Halt this week if they follow the same procedure as AHI, I am 50/50 on this, now that I have re-read the NASDAQ update announcement.
