About

Elizabeth A. Holmes, Theranos's founder and former chief executive, defended against conspiracy and wire-fraud charges concerning representations to investors and paying patients. Her counsel argued that she believed in the company's mission and technology, lacked an intent to defraud, and made business mistakes rather than committing crimes. The defense acknowledged problems in Theranos's clinical laboratory but attributed her understanding of test reliability to information from Balwani, laboratory directors, and scientific personnel.

Holmes testified from Day 36 through Day 43 in direct, cross, redirect, and recross examination. On direct examination, she described a cartridge problem discovered around a Novartis demonstration, the subsequent redesign of Theranos's analyzer, and research or evaluation work involving pharmaceutical companies, the Department of Defense, and other institutions. She presented those projects as validation or comparison efforts while acknowledging the small size of one study and that some proposed clinical work did not occur.

The prosecution tested her explanations about trade-secret protections, information shared with Walgreens and pharmaceutical companies, and Theranos's current capabilities. Holmes acknowledged that Theranos devices had not been used for clinical military care, that the company used third-party analyzers, and that she had not told PFM or Walgreens about modifications to those machines. On recross, Holmes confirmed that the Walgreens rollout did not expand beyond 41 stores, addressed the timing of a $75 million Walgreens fee, and agreed that investors were entitled to truthful answers about the company's current capabilities. Evidentiary rulings limited several documents to Holmes's state of mind rather than the truth of their contents, while broader customer-feedback reports remained excluded. Those limits defined how the jury could consider documents offered to explain her understanding and intent.

On Day 51, the jury found Holmes guilty of conspiring to commit wire fraud against Theranos investors and of investor wire fraud on Counts 6, 7, and 8. It found her not guilty of conspiring to defraud paying patients and not guilty on Counts 10, 11, and 12, while returning no verdict on Counts 3, 4, and 5. The court then declared a mistrial on those three counts. All 12 jurors individually confirmed the verdicts.

Defense counsel used laboratory procedures, email chains, workflow improvements, and a sample-volume patent to emphasize Theranos's monitoring and remediation systems and to narrow Cheung's expertise. Cheung nevertheless maintained that the vitamin D SOP was not followed, confirmed that hepatitis C was not run on Edison after her concerns, and described Edison as a one-patient, one-test device.

Mentioned in this proceeding.

ProceduralSafeway Renovation-Expense Evidence HearingMentioned

Summary

Defense counsel sought to exclude proposed testimony about Safeway's store-renovation spending, while prosecutors argued that the spending showed materiality; the court explored omitting the exact figure but did not rule in this excerpt. The court also prepared to question a juror concerned about continued service and confirmed that Alternate Juror 3 could remain.

Mentioned in this proceeding.

ProceduralLaboratory-Comparison Testimony Evidence HearingMentioned

Mentioned in this proceeding.

DirectSteven Burd β€” DirectSteven BurdRobert S. LeachMentioned

Summary

Former Safeway CEO Steven Burd testified that Holmes's representations about a fast, comprehensive mini-lab drove a strategic retail agreement, substantial payments, and convertible-note purchases. He also described a failed board demonstration, repeated rollout delays, and Safeway's unmet expectation that Theranos's own technology was operating and validated.

Mentioned in this proceeding.

Day 17

CrossSteven Burd β€” CrossSteven BurdKevin M. DowneyMentioned

Summary

Defense counsel used Safeway's extensive due diligence, commercial incentives, and contractual safeguards to challenge the nature of its reliance on Theranos.

Mentioned in this proceeding.

RedirectSteven Burd β€” RedirectSteven BurdRobert S. LeachMentioned

Summary

Steven Burd reaffirmed Safeway's reliance on representations about Theranos's maturity, finances, device capabilities, and regulatory progress. He said no Walgreens, laboratory, or device problem was given to him as the reason for the December 2012 delays and clarified that Safeway's $275 million figure concerned store remodeling, not payment to Theranos.
