There is obvious deal logic and virtue in David Ellison and Gerry Cardinale’s attempt to acquire National Amusements Inc., the parent company of Paramount Global, from Shari Redstone. After all, Shari controls nearly 80 percent of the voting rights of Paramount Global, along with some 10 percent of the economic value of the company. Those voting rights allow Shari to appoint Paramount’s board of directors and its executive leadership, through which she can do pretty much anything she wants at the company. She can unilaterally decide whether to sell an asset—say, Simon & Schuster—or to not sell an asset, say BET (or to revive the sale of it). She can also change the company’s charter or bylaws. And she hasn’t been the least bit shy in these regards, either. She hand-picked Bob Bakish as C.E.O., and she has pretty much hand-picked the Paramount Global board of directors.
