I think that they will (or they should) issue an update before the end of this week.
Those advising management should be urging them to issue an update to the market. That update must contains specific information surrounding the defective 3B and cleansing notice, the remedy and a projection for how long they expect that it will take to cure the defective parts of the 3B and cleansing notice.
Notwithstanding everything that has been said to date - they have a PR problem and they need to get on the 'front foot' and reassure their shareholders. If they can not see the capacity for the damage to company's reputation that the present circumstances is creating then they are in the wrong job.
You can sit in a dark room cursing the darkness whilst waiting for the lawyers to fix things for only so long.
Be resolute and keep holders informed. Oddly, these types of problems can provide the impetus for a change in direction for their corporate communications.
If I were the MD I would openly declare, "... we are not getting this stuff right ... we need someone who will ... we must set ourselves a higher standard than this."
My sentiment has not altered one iota.
This issue is a technical matter (as far as one can tell). They should not allow this issue to be enveloped by negative speculation (some classic examples of that exist on this thread). Strategic communication can be a powerful thing - use it!
