President Trump issued an executive order on January 2, 2026 blocking and reversing HieFo’s $2.92M acquisition of Emcore’s chip and wafer design and fabrication businesses, citing national security risks due to HieFo’s control by a Chinese citizen. The order mandates full divestment within 180 days under CFIUS oversight, restricts access to sensitive technical information, requires certification of IP transfer or destruction after divestment, and authorizes enforcement to prevent evasion.
