50% plus 1 share gains control of the company - they can then sack the board and put in their own people - I would think the MO would be similar to the way Gina got control of and eventually got to 90% acceptance and compulsory acquisition of the final 10% to take over Atlas Iron even though Twiggy had almost 20% at one point.
A bid at a premium to 90 day VWAP subject to min 50% acceptance would be how it would start ( IMO ) No one knows how many friends are already on the register behind the nom accounts and larger Chinese retail holders.
