I would assume that they would have made an offer already for the acquisition of whatever they are looking at acquiring. The offer may have been conditionally accepted, meaning that they would then need to finalise contracts which is still privy until the deal is sealed.

They can announce that they have something coming up which is still required by ASX as there will be an acquisition taking place and an announcement will be given to the market.

This is a little different to the contracts with carriers in my opinion as that is subject to trial and testing requirements first - This, is not.

But i agree. We all need to wait for Tuesday and see what golden apple or rotten fruit we are given
