I've never seen a company blame a data breach as the point where they started going bankrupt.
Customers never migrate on mass after a breach, 7000 underfunded and overworked education institutions are not migrating on mass.
So I feel safe to say there's no lasting impact to a company when a data breach occurs.
This will all be forgotten in a few months.
To be fair, I don't think I've ever seen a company identify the inflection point after bankruptcy, accurately or not.
