If it's a crypto wallet then your crypto is irreversibly gone.
If the breached data is "material" - i.e. gives someone an advantage in stock market decisions - you're going to get in a lot of trouble with the SEC.
If the breached data is PII you're going to get in trouble with all kinds of government agencies.
If it's PII for children you're in a world of pain.
Update: I found one story about a company going bankrupt after a breach, which is the closest I can get to "lethal": https://www.securityweek.com/amca-files-bankruptcy-following...
Also it turns out Mossack Fonseca shut down after the Panama papers: https://www.theguardian.com/world/2018/mar/14/mossack-fonsec...
