Can someone explain here the downside risk of not accepting the HCM offer and HCM obtaining over 50% control of Bradken? Will Paradice / Litespeed leave it until the last minute to announce whether they are accepting? If HCM gets control of the company can they deliberately bring down the share price?

I have done quite well with Bradken- they have been a 3 bagger for me so far but I have only held half my shares for over 12 months so wanted to hold out for the capital gains discount. I also see them increasing in value further but am not in a position to lose the gains I have made thus far. But I binned my voting forms as I thought even if HCM gain control and I had not accepted the offer I would still get $3.25 per share!
