Billionaire entrepreneur Patrick Soon-Shiong, whose NantHealth Inc. went public on Wednesday, says he has two more health companies in the pipeline.
Soon-Shiong is building an empire of intertwined companies that range across the health-care system. NantKwest Inc., which first sold shares to the public in July, is a cancer drugmaker focused on a part of the immune system called a natural killer cell, while NantHealth provides software and medical records systems to doctors and hospitals.
