Peltz, if he gets both seats he is after, will have a voice but will still be a minority on the 12 person board. Will it be enough? Maybe, but probably not.
What is more likely to have a major impact is the Florida criminal investigation. Based on the Independent Audit Disney management and the old RCID board are looking at major financial felonies in the 30 to life range. Further the municipal bonds could be invalidated. Calling it a mess is being kind.
By the way, the crimes being investigated are bond fraud (both state and federal) misuse of taxpayer funds and tax evasion.
