Shares are suing Apollo Global Management and its billionaire co-founders Leon Black and Marc Rowan for allegedly defrauding shareholders for nearly five years about the private capital firm's business dealings with Jeffrey Epstein, a disgraced financier. The shareholders allege that the defendants falsely denied ever doing business with Epstein, who was heavily involved and frequently communicated with Apollo's senior leadership about the company's business during the 2010s. The complaint also alleges that Rowan and other Apollo employees provided information to Epstein regarding his tax work for Black, but when Epstein sought to work for other co-founderers, he was declined at every turn. Black has denied wrongdoing and said he was unaware of Epstein's criminal conduct.
