. In October 2020, UMC and the U.S. Department of Justice reached a plea agreement, with UMC pleading guilty to one count of receiving and possessing a stolen trade secret and agreeing to pay a fine of $60 million. UMC’s plea and Plea Agreement resolved the 2018 trade secrets case brought against UMC by the U.S. Department of Justice. As part of the Plea Agreement, DOJ agreed to dismiss the original indictment against UMC, including allegations of conspiracy to commit economic espionage and conspiracy to steal multiple trade secrets from Micron Technology, Inc. (“Micron”), patent-related allegations, and alleged damages and penalties of $400 million USD to $8.75 billion. The one trade secret at issue in the guilty plea and Plea Agreement related to older technology that had been in mass production worldwide for several years. DOJ also dismissed a related civil case against UMC. Aside from the fine amount, UMC has no further financial obligations to DOJ. The Plea Agreement also provides that UMC will cooperate with DOJ and will be subject to a three-year term of non-supervised probation.
