Agreed, no noise from the ASX on this, because they’ve accepted AVZ’s explanation: “we didn’t think it was worth flagging with shareholders”.
Whether an independent court agrees with that judgment, or whether it was good/fair judgment, is the question.
I think many shareholders probably now wish they’d been made aware a lot earlier, and not given a grand total of just 3 trading days between first disclosure, and then trading halt. Very little chance given to digest the news, consider the implications, and take action. The smart ones got out fast though - explains why the price fell from $1.18 to $0.78 on very high volume over those three days.
But the ASX lets a lot of things slide and is fairly well-known for doing too little, too late.
