Disgraced Theranos founder Elizabeth Holmes will serve just over 10 years behind bars after a federal judge trimmed her prison sentence by a year — while stressing her massive fraud still warrants serious punishment.

US District Judge Edward Davila on Thursday took 12 months off her original sentence of 11 years and three months due to changes to federal guidelines for first-time, non-violent offenders.

Earlier this year, Holmes appealed to President Trump for an early release from prison — a full six years before she is eligible for parole.

The newly revised term of 123 months places Holmes squarely in the middle of a new sentencing range of 108 to 135 months, under the revised guidelines.

The reduced sentence was first reported by Bloomberg.

"To be clear, this sentence reduction does not diminish the enormity of Holmes's crimes," Davila wrote in his ruling, adding that the "significant negative impact her conduct has had on the community" remains unchanged.

The decision hands Holmes a victory — and deals a blow to federal prosecutors who fought to keep her full sentence intact.

She qualified for the reduction under a 2023 amendment to sentencing guidelines that allows certain offenders with no prior criminal history to receive shorter prison terms.

At issue was whether Holmes' fraud caused "substantial financial hardship" — a key factor that could have disqualified her from a sentence reduction.

Prosecutors said it did, pointing to more than $450 million in losses and restitution owed to victims.

The court rejected that argument.

Davila found no evidence that any individual investor suffered the kind of personal financial devastation required under the guideline, noting that even probation officials couldn't identify a victim who met that threshold.

That finding cleared the way for Holmes to receive the sentence reduction — despite the scale of the fraud tied to her failed blood-testing startup, Theranos.

The judge cited Holmes' clean prison record as a factor that weighed in her favor.

Since beginning her sentence at the women's minimum-security Federal Prison Camp Bryan in Texas over two years ago, she has not incurred a single disciplinary infraction.

Holmes has also participated in rehab programs while helping fellow inmates, according to court filings.

Prosecutors pushed back on the sentence reduction, arguing Holmes remains a risk to reoffend.
