U.S. District Judge Denise Cote's ruling came several weeks after a seven-day bench trial in December. The Federal Trade Commission and seven states brought the case in 2020 against the man dubbed "Pharma Bro" in the media.
Shkreli's lawyer did not immediately respond to a request for comment.
Shkreli was CEO of Turing Pharmaceuticals — later Vyera — when it jacked up the price of Daraprim from $13.50 to $750 per pill, after obtaining exclusive rights to the decades-old drug in 2015. It treats a rare parasitic disease that strikes pregnant women, cancer patients and AIDS patients.
He defended the decision as capitalism at work and said insurance and other programs ensured that people who need Daraprim would ultimately get it.
But the move sparked outrage from medical centers to Congress to the 2016 presidential campaign trail, where candidate Hillary Clinton termed it price-gouging and future President Donald Trump called Shkreli "a spoiled brat."
hkreli eventually offered hospitals half off — still amounting to a 2,500% increase. But patients normally take most of the weekslong treatment after returning home, so they and their insurers still faced the $750-a-pill price.
He resigned as Turing's CEO in 2015, a day after he was arrested on securities fraud charges related to hedge funds he ran before getting into the pharmaceutical industry. He was convicted and is serving a seven-year prison sentence.
Vyera Pharmaceuticals was sued in federal court in New York by the FTC and seven states: New York, California, Illinois, North Carolina, Ohio, Pennsylvania and Virginia.
They alleged that Vyera hiked the price of Daraprim and illegally created "a web of anticompetitive restrictions" to prevent other companies from creating cheaper generic versions by, among other things, blocking their access to a key ingredient for the medication and data the companies would want in order to evaluate the drug's market potential.
Vyera and its parent company, Phoenixus, settled last month, agreeing to provide up to $40 million in relief over 10 years to consumers and to make Daraprim available to any potential generic competitor at the cost of producing the drug.
Former Vyera CEO Kevin Mulleady agreed to pay $250,000 if he violates the settlement, which bars him from working for a pharmaceutical company for seven years.
Shkreli proceeded to trial.
