Trump Blocks HieFo-Emcore Chip Deal Citing National Security

• President Trump blocked HieFo Corp.'s acquisition of semiconductor assets from Emcore Corp. due to national security concerns.
• HieFo, a Delaware-based company, is controlled by a Chinese citizen, raising alarms over access to advanced chip technology.
• The deal, announced in 2024 for $2.92 million, involved Emcore's digital chips and wafer fabrication businesses.
• The order mandates HieFo to divest the assets within 180 days, unless the Committee on Foreign Investment in the United States (CFIUS) grants an extension.
• This action is part of the administration's broader effort to restrict Chinese access to critical U.S. semiconductor technologies.
