Theranos (2015): Walgreens and the consumer claim

On 15 October 2015 the Wall Street Journal published John Carreyrou’s investigation reporting that the firm used conventional machines for many tests and that the proprietary devices were not doing what the company claimed. Federal and state health regulators, the SEC, and the Department of Justice followed with inspections, civil charges, and criminal indictments.

A jury in the U.S. District Court for the Northern District of California convicted Holmes on 3 January 2022 of conspiracy to commit wire fraud and three counts of wire fraud against investors. Judge Edward J. Davila sentenced her on 18 November 2022 to 135 months in prison. Ramesh ‘Sunny’ Balwani, the former president and chief operating officer, was convicted in July 2022 and later sentenced to 155 months. Patient-related counts against Holmes did not produce convictions.

The Journal’s 2015 series, CMS inspection files, the SEC complaint, and two federal criminal trials in San Jose are the primary sources. They describe investor fraud proved to a jury, not a scientific mystery still waiting for a device. Theranos raised capital on the promise of decentralized, low-volume blood testing. A 2013 partnership with Walgreens put collection sites in stores and made the claim a consumer-facing fact, not only a Silicon Valley pitch.
