Who is next?
The HP board. They have to do this to pretend they were not stupid and culpable and therefore liable themselves to a shareholder law suit.
HP's lawyers. Deal like this the buyer sends in not just a platoon but a whole army of lawyers to check everything,
HP's accountants. Ditto.
HP's lawyers insurers. They will ultimately pick up the tab, as will
The Board's executive liability insurers and
The accountants' insurers.
Then the insurers bump up their premiums. Probably already did. So all their insureds pay.
Did I forget anyone? Oh yes - the bankers who advised on the deal. But they are the ones who always have an explanation why a magic deal turns out to be a disaster.
Ho-hum. Keeps the wheels of capitalism turning.
