AJD can try to buy up to 50% in an attempt to roll the current board to drive the company in the direction it wants but that's about it. They can't get enough votes for a scheme arrangement or abither major change to pass with out NXT's approval with their 30% stake. I'd expect things to stayuch the same (same/ similar board and corporate strategy) unless NXT sells out or comes back with a new bid.

The underlying income for AJD will be the same after this, so I wouldn't be surprised to see the share price drift back closer to the pre-takeover price as supported by the yield. There will probably still be some premium in the price due to speculation of a new NXT offer and the reduced liquidity from them holding 30% (assuming it isn't dumped).
