Elizabeth Holmes — the Silicon Valley wunderkind whose blood-testing startup Theranos has collapsed in a slew of scandals — has been charged with “massive fraud” by the Securities and Exchange Commission.

The SEC on Wednesday accused Theranos CEO Holmes and a top lieutenant of defrauding investors of more than $700 million through false claims about its technology.

Holmes — a Steve Jobs wannabe who dressed exclusively in black turtlenecks as she talked up her blood-testing unicorn, which at one point boasted a valuation north of $9 billion — settled with the regulators for $500,000 while neither admitting nor denying the accusations.

Theranos disclosed in a 2016 letter to investors it was under a criminal probe. No criminal charges have been filed, and it’s not known if the investigation is ongoing.

Holmes additionally agreed to not be a director or officer of a public company for 10 years, and to forgo profiting from Theranos ownership until $750 million is returned to investors, according to the consent order with the SEC.

Theranos and 34-year-old Holmes ran “an elaborate, years-long fraud in which they exaggerated or made false statements about the company’s technology, business, and financial performance,” according to the SEC.

While Theranos had said it was on track to make $100 million by the end of 2014, the real figure was “a little more than $100,000,” according to the SEC. And, contrary to what Theranos told investors about the Department Defense using its blood tests, they were “never deployed by the DOD in the battlefield, in Afghanistan, or on medevac helicopters,” according to the settlement.

The disgraced CEO also misled employees about its institutional backing, according to the charges. Theranos distributed pitch books to investors containing articles purportedly written by other pharmaceutical executives — lending the startup institutional clout —but were in fact written by company employees, according to the charges.

Ramesh “Sunny” Balwani, the company’s president and chief operating officer, is fighting the charges.

“Investors are entitled to nothing less than complete truth and candor from companies and their executives,” Steve Peikin, the SEC’s head of enforcement, said in a statement.

The charges amount to one of the biggest scandals to rock the tech world since the bursting of the tech bubble in 1999.

The SEC claims that Holmes misled investors about her technology, which Theranos said was able to test for diseases with only a pinprick, and more cheaply than what was commercially available, according to the SEC settlement.

In reality, the company didn’t have any reliable technology to test blood samples, and sent blood to third-party companies for testing, according to the complaint.

The settlement marks a further humiliation for Holmes, a Silicon Valley star who at one point was the youngest self-made woman billionaire with $4.5 billion in net worth.

Theranos started to unravel in 2015 after the Wall Street Journal reported that its blood tests were actually being conducted by commercial analyzers, and that the actual technology wasn’t special.

That day, Holmes went on “Mad Money” with Jim Cramer to rebuff the charges, and claimed the paper was out to stifle innovation.

“First they call you crazy, then they fight you, then you change the world,” she said on CNBC, paraphrasing a quote that’s often misattributed to Mahatma Gandhi.

Lawyers for Holmes and Theranos weren’t immediately available for comment.
