The verdict is the second conviction against Theranos leadership and comes six months after a jury found Ms. Holmes guilty of fraud. It secures another major victory for the US government, which brought the case against the pair in 2018. It brings to an end one of Silicon Valley’s most infamous startup booms, which saw nearly $1 billion of investors’ money evaporate following revelations that the company delivered inaccurate blood-test results to patients, including with life-threatening conditions, and that Ms Holmes and Mr Balwani lied about its proprietary technology.
