Re: equifax stock price still ~$90
"Since sep8 it has only dropped around $50. I would have expected much worse"
They haven't lost any customer data. They've only lost some data that they were selling anyway, nothing for their customers to be overly worried about. There's just a one-off cost involved to be seen to be doing something now, but other than that there shouldn't be too much impact on long-term proffitablity from this. (sadly).
