Elizabeth Holmes, former CEO of Theranos, arrives at the federal courthouse in San Jose, Calif., on Oct. 1, 2021.

A federal judge on Monday ordered that the sentencing of Theranos founder and CEO Elizabeth Holmes, scheduled for Oct. 17

be delayed. Judge Edward Davila plans to hold an evidentiary hearing on her request for a new trial.

Earlier this year a jury convicted Holmes of four counts of defrauding investors regarding the Palo Alto company Theranos' blood-testing technology.

The jury acquitted Holmes of four counts of defrauding patients. Jurors were unable to reach a verdict on three other investor-related charges.

Holmes faces up to 20 years in prison and a fine of up to $250,000 on each of the four counts of wire fraud.

Davila denied Holmes' motion for acquittal in September. Holmes then filed three motions for a new trial based on newly discovered evidence.

Monday's hearing focused on Holmes' request for a new trial, which is based on a surprise visit to her home last summer by key prosecution witness, former Theranos Lab Director Adam Rosendorff.
