I'm not a lawyer but I suspect the answer would depend on what has been previously disclosed, which, as far as I a aware, is that they plan/expect to be net-cash by the middle of the year. If they ended up being in that position in say, April, then I would expect that would need to be announced as it would be earlier than previously announced and would be price sensitive.
Once again I am not a lawyer and more than happy to be corrected. DYOR.
A director shouldn't be saying anything that he wouldn't tell anyone else or the market first - so not sure why sharing would be a problem?
