Trump Bars HieFo's Acquisition of EMCORE Chip Assets and Orders Full Divestment Within 180 Days
On January 2, 2026, in Washington, President Donald J. Trump signed an order prohibiting HieFo Corporation's acquisition of EMCORE Corporation's chip assets and directing HieFo to divest all of those assets within 180 days. The order found credible evidence that the transaction might threaten to impair the national security of the United States.
HieFo is a Delaware company controlled by a citizen of China. The barred transaction was completed on April 30, 2024, and covered EMCORE's digital chips and related wafer design, fabrication and processing businesses; EMCORE is a New Jersey corporation, and the wafer operations are in Alhambra, in Los Angeles County, California. The order rests on section 721 of the Defense Production Act of 1950, the statute behind reviews by the Committee on Foreign Investment in the United States (CFIUS).
Under the order, HieFo and its affiliates must divest all interests and rights in the EMCORE assets within 180 calendar days, including contracts, inventory, tangible property, fixed assets, accounts receivable, permits, real property and intellectual property, unless CFIUS extends the deadline. Before any sale or transfer to a third party, HieFo must notify CFIUS of the intended buyer in writing and wait 30 calendar days without a CFIUS objection.
Until the divestment is completed and verified by CFIUS, HieFo may not grant anyone who is not its own personnel access to the EMCORE assets or to their non-public technical information, information systems, books and records or U.S. facilities, and it must certify compliance to CFIUS weekly. CFIUS is authorized to audit and impose conditions, the Attorney General may enforce the order, and the Secretary of the Treasury is directed to transmit it to the parties.
