The decline of Theranos began in 2015, when a series of journalism and regulatory investigations revealed doubts about the company’s technology claims and whether Holmes had misled investors and the government. In 2018, the U.S. Securities and Exchange Commission charged Theranos and Holmes with deceiving investors by “massive fraud” through false or exaggerated claims about the accuracy of the company’s blood-testing technology; Holmes settled the charges by paying a $500,000 fine, returning 18.9 million shares to the company, relinquishing her voting control of Theranos, and being barred from serving as an officer or director of a public company for ten years.
