Sadly so.
But...
That should automatically lead to another big fine...
No, the EU fine is imposed to change the behaviour of the corporation.
If the corporation's shareholders are stupid enough to reward management for provoking such a fine by providing a golden parachute to them for getting the company fined and losing the shareholders lots of money then that's the shareholders' own free decision.
If that leads to the new management thus incentivized provoking even bigger fines or even more severe consequences, that is again the shareholders' prerogative to have that happening – at their own expense by losing even more money in the process!
If shareholders run their own company into a ditch they can perfectly well do that on their own money!
Only if management defrauded the shareholders by violating corporate regulations about transparency and proper reporting
then shareholders could possibly have legitimate claims against said management, but not if they themselves had deliberately sanctioned management misdeeds with open eyes!
