US President Donald Trump has blocked HieFo Corp's $3 million acquisition of Emcore Corp, citing national security concerns related to its Chinese ownership. The White House order mandates HieFo to divest its interests in Emcore within 180 days. The Committee on Foreign Investment in the US (CFIUS) identified risks regarding access to Emcore's intellectual property and the potential diversion of indium phosphide chips. Emcore's chips business was sold for $2.92 million, with HieFo co-founded by former Emcore executives.
