“There is nothing worse than being told that your daughter is going to die,” https://www.forbes.com/sites/chloesorvino/2018/06/20/how-ceo-martine-rothblatt-turns-moonshots-into-earthshots/" aria-label="Rothblatt told Forbes">Rothblatt told https://www.forbes.com/sites/chloesorvino/2018/06/20/how-ceo-martine-rothblatt-turns-moonshots-into-earthshots/">Forbes in 2018. “I just said I will find a way, or she was going to die, because all of the previous people with this illness had died.”
Nearly three decades later, Rothblatt’s daughter is healthy and in her 30s. Meanwhile, shares of the now publicly traded firm, United Therapeutics, are up 54 times its price at its 1999 IPO. This year alone, shares have surged, up 50% so far in 2024 and up 40% since April 30—enough to make Rothblatt the world’s newest billionaire.
