It's a process. 1st they would need to make a formal proposal then the board would notify shareholders and consider it, and negotiate if it has merit, after which it gets put to shareholders. Usually if the board back it it gets up (because the board usually represent the major shareholders). At which point you would get cash for your shares (assuming it's a cash offer).
I think a takeover is highly unlikely. A low ball offer may come but SRF are not in a position where they would need to entertain unfavourable offers.
