With the finish line in sight, it appears that Shari Redstone is getting somewhat greedy, retrading deal points and asking for legal indemnifications as part of David Ellison and Gerry Cardinale’s generous $2 billion offer for National Amusements Inc., the family holding company. Their offer already includes a buffet of sweeteners to help the transaction go down smoothly, allowing Ellison and Cardinale to take control of Paramount Global. But Shari, as I reported on Wednesday, is wary of shareholder litigation. To inoculate herself, she now wants the majority of the non-Redstone voting “A” shareholders to approve the Ellison/RedBird deal, essentially putting her fate in the hands of the long-suffering Mario Gabelli, with his 5 million Class A shares. If Shari persists, I’m told, that could be a legit dealbreaker for David and Gerry.
