President Donald Trump issued an executive order in early January 2026 requiring HieFo Corp. to divest (sell off) computer chip and wafer-fabrication assets it bought from Emcore Corp. in a deal valued at about $2.9 million (including assumed liabilities). The order says the transaction threatens U.S. national security if the current owner remains in control, and it gives HieFo 180 days to complete the divestment.

According to reporting on the decision, the U.S. government cited “credible evidence” that HieFo is controlled/owned by a citizen of the People’s Republic of China, and the action followed a national-security review process (CFIUS) that concluded the deal posed risks (without publicly detailing the specific threats). The original purchase was completed in May 2024, and the assets were expected to continue operating with largely the same California-based team.
