Good that you do not post in the threads to do with climate, because you never did know much about it.
On topic, AZM has very little cash, and no present financing facility, so will require a very large capital raising if it is ever to proceed. The takeover offer gives it a chance, and often there is a subsequent small increase to the initial offer, so maybe there is fractional upside.
Not a stock I was ever interested in, but if I had shares I would be accepting the offer price.
