Theranos founder Elizabeth Holmes has been found guilty of 4 fraud-related charges after a monthslong federal trial

• Elizabeth Holmes was found guilty of four fraud-related charges after a week of jury deliberation.
• Jurors found her not guilty on four more counts and failed to reach a verdict on three others.

Elizabeth Holmes has been convicted on numerous counts after a monthslong federal fraud trial.

The Theranos founder on Monday was found guilty of three counts of wire fraud and one count of conspiracy to commit wire fraud. She was found not guilty on four other counts, and jurors were unable to reach a unanimous verdict on the remaining three counts against her.

The four counts for which Holmes was convicted were one count of conspiracy to defraud investors and three counts of wire fraud related to investments made by the hedge fund manager Brian Grossman, the DeVos family, and the former Cravath attorney Daniel Mosley.

Holmes was acquitted of all counts related to patients who took Theranos tests.

The three counts that deadlocked the jury were for wire fraud in connection with investments made by the Black Diamond Ventures founder Chris Lucas, the former money manager and financial planner Alan Eisenman, and Bryan Tolbert, who is vice president of finance at the investment firm Hall Group.

The mixed verdict arrived on the jurors' seventh day of deliberations. Only hours earlier, the judge had instructed them to keep deliberating after they told the court they were deadlocked on three counts.

Holmes was charged with nine counts of wire fraud and two counts of conspiracy to commit wire fraud. The Justice Department alleged that Holmes and Ramesh "Sunny" Balwani, Theranos' former president and chief operating officer, schemed to defraud investors, doctors, and patients by making false claims about Theranos' technological abilities and finances and by hiding information about issues with the company's blood-testing machines.

Each count carried with it a maximum 20-year prison sentence, a $250,000 fine, and a requirement to pay restitution.

In recent weeks, investors, patients, doctors, and former Theranos employees took the stand against the one-time Silicon Valley superstar.

Prosecutors in Holmes' case called 29 witnesses to testify over 11 weeks. Among them were former Theranos employees who said they sounded the alarm on testing issues to no avail, former investors and board members who described being wooed by claims they now know to be false, and Theranos patients who recounted inaccurate test results.

The defense leaned largely on testimony from Holmes, who was its last of just three witnesses, to make its case.

On the stand for seven days, Holmes frequently deflected blame, saying she relied on Balwani, lab workers, and others for information about Theranos and had no reason to doubt them when they reported good news about the company.

Still, Holmes made several key admissions.

She acknowledged adding logos from Pfizer, GSK, and Schering-Plough to company reports without authorization but said no one from the pharmaceutical firms later objected or told her to remove the logos. Holmes also acknowledged hiding Theranos' use of modified third-party devices but said she did so because she considered the modifications trade secrets to be protected. She conceded trying to kill The Wall Street Journal's exposé on the company, again leaning on her trade-secret defense.

Holmes also expressed regrets for some actions, including Theranos' handling of a whistleblower's claims and her approach to a Fortune article that helped catapult Holmes to fame but contained inaccuracies.

Holmes dropped out of Stanford at 19 to build Theranos. The company was valued at $9 billion at its peak, earning Holmes recognition as the world's youngest self-made female billionaire in 2015. It was hailed as a revolutionary force in healthcare and counted former senators, US secretaries of defense, and billionaire CEOs among its investors and board members.

Theranos' public downfall kicked off in 2015, when a Wall Street Journal investigation found Theranos couldn't perform nearly as many tests as advertised and relied heavily on third-party devices, not its proprietary ones. The startup shut down in 2018.

The Theranos saga has exposed the most extreme repercussions of Silicon Valley's "fake it till you make it" culture, identified holes in the traditional due-diligence process, and challenged the girlboss feminism for which Holmes was a poster child.

Balwani's trial is scheduled to begin in February.
