The Elizabeth Holmes Verdict: Theranos Founder Is Guilty on Four of 11 Charges in Fraud

At the 15-week trial, Ms. Holmes testified in her own defense, showing regret for missteps and saying she never intended to mislead anyone. She accused her former boyfriend and deputy at Theranos of abusing her, allegations he has denied.

Ms. Holmes was charged with nine counts of wire fraud and two counts of conspiracy to commit wire fraud under an indictment brought 3 ½ years ago.

She was found guilty on three of the nine fraud counts and one of two conspiracy counts. She was acquitted on four counts related to defrauding patients—one charge of conspiracy to commit wire fraud and three charges of wire fraud.

The jury failed to reach a verdict on three counts, after saying earlier Monday it was having difficulty reaching consensus on three of the charges.

The 12 jurors looked impassively at the judge’s deputy, Adriana Kratzmann, as she read the verdicts aloud. Ms. Holmes and her attorneys also looked straight ahead, unflinching, as the jury’s decisions were read.

Ms. Holmes embraced her family and friends before departing the courtroom. Her partner, Southern California hotel heir Billy Evans, raced outside the courtroom after the jury left and waited as Ms. Holmes huddled with her lawyers in a separate room in the courthouse.

Prosecutors can choose to pursue a new trial on the undecided counts. The timing of any new action by the U.S. against Ms. Holmes would likely be affected by an upcoming trial of Ramesh “Sunny” Balwani, Ms. Holmes’s former boyfriend and deputy at Theranos who faces similar charges of defrauding investors and patients about the startup’s blood-testing capabilities, which he denies.

Prosecutors had to prove she intended to defraud investors and patients, seeking a financial windfall. Ms. Holmes countered with testimony saying she made innocent mistakes and believed that Theranos’s blood-testing technology was showing signs of success.

​The jury wasn’t fully convinced by testimony from investors who testified they had lost money after buying into Ms. Holmes’s vision. Some said they had invested even after Ms. Holmes rebuffed their requests for more information, which defense lawyers said showed negligence on their part. The 37-year-old Ms. Holmes could face up to 20 years in prison for each count for which she was found guilty, but former prosecutors said such a stiff sentence is rare in white-collar fraud cases. That Ms. Holmes was acquitted of any charges likely lessens the overall penalty she will face, former prosecutors said. Sentencing will follow.

Testimony from the three patients who received what they called false test results was limited, and the role of their healthcare providers in ordering and interpreting their tests may have also tripped up jurors, legal experts say.

The U.S. government, in a rare fraud prosecution of a technology executive, essentially put on trial Silicon Valley’s fake-it-until-you-make-it culture. In Theranos’s case, prosecutors said Ms. Holmes’s hype and hubris went far beyond norms, exposing patients and investors to harm by peddling faulty technology. It was one of the most high-profile white-collar criminal trials in years.

“She chose to be dishonest with her investors and with patients,” Assistant U.S. Attorney Jeff Schenk said of Ms. Holmes in his closing arguments to the jury. “That choice was not only callous, it was criminal.”

The mixed verdict, by a jury of four women and eight men, put a punctuation mark on a scandal that surfaced with a series of Wall Street Journal articles in 2015 and 2016 that called into question Theranos’s proprietary blood-testing technology.

In 2018, Ms. Holmes settled separate civil securities-fraud charges brought by the Securities and Exchange Commission; she paid a $500,000 penalty and was banned from being an officer or director of any public company for 10 years, without admitting or denying the allegations.

Theranos rose nearly two decades ago out of an idea Ms. Holmes dreamed up as a 19-year-old student at Stanford University. She sought to upend the blood-testing business by developing technology that tested for a range of health conditions with just a few drops of blood from a finger prick, eliminating the need for large needles and vials of blood.

Ms. Holmes recruited a star-studded board of Washington insiders, including former Secretaries of State Henry Kissinger and

George Shultz,

who knew little about healthcare but were drawn in by her vision and conviction about Theranos’s prospects. The board lent the company prestige and helped attract high-profile investors.

At its peak, investors valued Theranos at more than $9 billion, the 10th largest among venture-capital-backed startup companies. Ms. Holmes owned half of it, with a paper value of around $4.5 billion, she testified during her trial. The company employed hundreds of scientists, engineers and marketers, and Ms. Holmes claimed it could cheaply and quickly run more than 200 health tests using a proprietary device. In a partnership, Theranos offered the tests at Walgreens pharmacies.

The trial showed a different reality. The company managed to use its proprietary finger-prick blood-testing device for just 12 types of patient tests. Those results were unreliable. At its lab, Theranos secretly ran most of its blood tests on commercial devices from other companies, including some that Theranos altered to work with tiny blood samples.

In her testimony, Ms. Holmes repeatedly said she had regret for some of her business decisions: “There are many things that I wish I did differently,” she said on the witness stand.

She insisted, however, that she never set out to defraud anyone: “I believed in the company, and I wanted to put everything that I had into it.”

The government called 29 witnesses in its effort to prove Ms. Holmes committed fraud. They included former Theranos employees who recounted how Ms. Holmes and her deputy dismissed warnings about questionable test results from the company’s lab while creating a culture of fear, isolation and retaliation.

Jurors learned during the trial that Ms. Holmes forged reports provided to some investors and partners such as Walgreens Boots Alliance Inc.’s U.S. drugstore unit by adding logos of

Pfizer Inc.

and other major drug companies without permission from the companies. Prosecutors showed in court how text had been deleted and added to the documents, which some investors said in testimony appeared to them to be complimentary validation reports from the drug companies.

Woven together, the evidence and testimony illustrated a startup that encountered numerous technological and operational challenges and masked its problems to try to stay afloat. All the while, Ms. Holmes was in charge. Asked by a prosecutor if the buck stopped with her, Ms. Holmes replied, “I felt that.”

Investors took the stand to describe how Ms. Holmes made what they later concluded had been misleading sales pitches, falsely claiming Theranos devices were being used by the military and that the company was on track to make nearly $1 billion in annual revenue in 2015. They said Ms. Holmes’s marketing effort persuaded them to sink millions of dollars into the company.

Patients described receiving test results they believed were simply wrong. One result indicated that a woman could be HIV positive; another wrongly led a pregnant woman to believe she was miscarrying. Scientists from drug companies testified that they had thought Theranos’s technology was unimpressive; one called Ms. Holmes “cagey.”

In the trial’s most dramatic turn, Ms. Holmes made a bold gamble to testify on her own behalf. Projecting confidence, smiling at times and maintaining her composure, Ms. Holmes made her case fully in public for the first time. She was the last of three defense witnesses.

She said over seven days on the stand that she had honest intentions to improve healthcare but conceded to mistakes and obfuscations. “I wanted to convey the impact the company could make for people and for healthcare,” she said of her pitch to investors.

Her testimony also exposed her to tough questioning by government lawyers about how they said she misled investors, berated whistleblowers and altered documents.

Ms. Holmes conceded that she doctored reports sent to investors by affixing logos of drug companies. She conceded that Theranos’s proprietary device had only…
