Run! Don't walk! Run to the exit!
SS&C will do nothing to expand the company. Consider your company culture, your identity, your special benefits (whatever they may be) gone. Year 1 will be a tight hand around the purse strings. Year 2 will be massive changes to your work place and replacement of some staff. Year 3 will be the massive slaughter. They will NOT appreciate you. They will NOT reward you. They WILL replace you. Don't give this place a bit of your talent.
