The Committee on Foreign Investment in the US (CFIUS) identified a national security risk in its investigation of the deal, the US Department of the Treasury said after Trump’s order. The statement did not specify the national security risk. Emcore, publicly traded at the time of the deal and later taken private, said HieFo bought its chips business and indium-phosphide wafer-fabrication operations for US$2.92 million.
