Lead:<\/strong> President Donald Trump on Friday ordered HieFo Corporation, described in a White House executive order as controlled by a citizen of the People\u2019s Republic of China, to divest a $2.9 million purchase of digital chip assets from U.S. manufacturer Emcore. The order, issued after a Treasury Department review, said the April 30, 2024 acquisition raised national security concerns, particularly over access to Emcore intellectual property and the possible diversion of indium phosphide chip supply. HieFo must divest the acquired assets within 180 days and immediately restrict access to Emcore technical information, the order directs. The move follows Treasury and CFIUS scrutiny of a transaction that was not notified to regulators.<\/p>\n

Key Takeaways<\/h2>\n
    \n
  • The White House issued an executive order requiring HieFo Corporation to unwind its $2.9 million acquisition of Emcore\u2019s digital chips and related wafer design and fabrication assets, citing national security risks.<\/li>\n
  • Treasury said the transaction, closed April 30, 2024, was not notified to the Committee on Foreign Investment in the United States (CFIUS) and was flagged by CFIUS\u2019 non-notified transactions team.<\/li>\n
  • CFIUS identified potential access to Emcore\u2019s intellectual property, proprietary know-how and expertise as the central risk, and specifically noted concerns about indium phosphide chip supply diversion away from the U.S.<\/li>\n
  • HieFo was ordered to divest all acquired assets within 180 days and to immediately restrict access to Emcore\u2019s technical data and facilities, including a manufacturing site in Alhambra, California.<\/li>\n
  • HieFo maintains it engaged nearly all key scientists, engineers and operational staff and said continuing operations at the Alhambra facility was a priority in a Sept. 2, 2024 statement.<\/li>\n
  • Emcore, a maker of navigation gyroscopes and sensors used across commercial, industrial and defense applications, was delisted from Nasdaq in early 2025 after a November 2024 merger with Velocity One LP.<\/li>\n
  • The Global Times, citing an expert, framed the divestment order as reflecting Washington\u2019s anxiety about technology competition with China and questioned the rationale.<\/li>\n<\/ul>\n

    Background<\/h2>\n

    The reviewed transaction began when HieFo acquired Emcore\u2019s digital chips business and associated wafer fabrication and processing capabilities on April 30, 2024. Emcore\u2019s digital chips include indium phosphide devices used in specialized navigation, sensing and communications applications; the company\u2019s work spans commercial and defense markets. HieFo was incorporated in Delaware and \u2014 according to the White House executive order \u2014 is controlled by a citizen of the People\u2019s Republic of China, a fact that triggered heightened review under national security authorities.<\/p>\n

    CFIUS, the interagency committee that evaluates foreign investments for national security risks, operates both a voluntary notification process and a non-notified transactions team that can open reviews when deals raise concerns. In recent years CFIUS scrutiny has expanded in parallel with broader U.S. efforts to limit foreign access to advanced semiconductor technologies and to protect sensitive defense-related supply chains. The U.S. government has increasingly treated certain materials and device classes, including indium phosphide photonics, as components with dual-use or niche defense relevance.<\/p>\n

    Main Event<\/h2>\n

    The Treasury Department said its non-notified transactions team reviewed the HieFo\u2013Emcore acquisition after identifying national security issues, and the White House subsequently issued an executive order directing HieFo to divest the acquired assets. The action instructs immediate restrictions on access to Emcore technical information and sets a 180-day deadline for divestiture of the digital chips and wafer fabrication businesses. The order emphasized protection of intellectual property and know-how tied to the transaction.<\/p>\n

    HieFo\u2019s acquisition included Emcore\u2019s facility in Alhambra, California, and \u2014 according to a company statement dated Sept. 2, 2024 \u2014 the buyer had engaged nearly all key scientists, engineers and operational staff to continue manufacturing and operations. Treasury flagged the potential diversion of indium phosphide chips, a specialized component, away from U.S. use as a specific national security concern. Emcore\u2019s product lines supply navigation and sensor systems used in civilian and military contexts, a factor agencies said increased sensitivity.<\/p>\n

    CFIUS\u2019 intervention stemmed in part from the transaction not being filed voluntarily for review. Under recent practice, non-notified reviews can lead either to mitigation agreements or to unwind orders if agencies conclude the risks cannot be mitigated. In this case, the executive order requires full divestment rather than negotiated mitigations, signaling the agencies judged the risk material and unresolved by less severe remedies.<\/p>\n

    Analysis & Implications<\/h2>\n

    The order underscores an elevated U.S. posture toward foreign acquisitions that touch on critical materials and specialized semiconductor production. Indium phosphide is a niche substrate used in photonics and high-performance optoelectronics; although not a commodity semiconductor, its role in sensors and high-frequency components gives it outsized importance for certain defense and navigation systems. Restricting foreign control of those capabilities narrows potential supply-chain vulnerabilities.<\/p>\n

    For outbound and inbound investors, the case signals that CFIUS and Treasury will weigh not only ownership and control but also the specific technical footprints of acquired assets. Deals that transfer manufacturing capacity, engineering teams and proprietary process knowledge for specialized device classes may face tougher scrutiny. This could depress M&A activity in targeted subsectors or push buyers to seek pre-closing mitigation agreements and voluntary notifications to reduce reversal risk.<\/p>\n

    On the diplomatic front, the order may escalate tensions with Beijing and with Chinese companies active in U.S. technology markets. State-linked or Chinese-controlled firms have increasingly found U.S. acquisition paths constrained; Beijing-aligned media framed the move as evidence of U.S. anxiety over tech competition. Conversely, U.S. national security officials argue such steps are necessary to protect critical capabilities tied to defense systems and navigation infrastructure.<\/p>\n

    The timeline shows roughly nine months between the April 2024 acquisition and the September public statement, and roughly 21 months between acquisition and the executive order. That interval reflects the time regulators may take to detect non-notified deals, review technical risks, and escalate to formal action. For companies, earlier voluntary notification could shorten uncertainty and provide options such as mitigation agreements instead of compelled divestiture.<\/p>\n

    Reactions & Quotes<\/h2>\n

    Officials framed the order as a targeted protection of sensitive U.S. capabilities, while media in China presented a contrasting view.<\/p>\n

    \n

    “CFIUS identified a national security risk arising from the transaction relating to potential access to EMCORE’s intellectual property, proprietary know-how, and expertise.”<\/p>\n

    U.S. Department of the Treasury (official statement)<\/cite><\/p><\/blockquote>\n

    The Treasury described the risks to IP and potential diversion of specialized chip supply as central to the decision, noting the transaction had not been notified to CFIUS. The department said HieFo must restrict access to technical information immediately and complete divestiture within 180 days.<\/p>\n

    \n

    “The divestment order reflects Washington’s anxiety over technology competition with China and was issued without a convincing rationale, according to an expert.”<\/p>\n

    Global Times (state-affiliated media)<\/cite><\/p><\/blockquote>\n

    The Global Times echoed an expert view that framed the decision as politically driven; that perspective contrasts with U.S. officials who cite narrow technical and supply-chain concerns. The competing narratives highlight the geopolitical sensitivity of technology controls and cross-border investment scrutiny.<\/p>\n

    \n

    “The purchase was intended to keep operations at the Alhambra facility running and retain key technical staff.”<\/p>\n

    HieFo (Sept. 2, 2024 company statement)<\/cite><\/p><\/blockquote>\n

    HieFo\u2019s earlier public statement emphasized operational continuity and retention of scientists and engineers. That claim is consistent with the firm\u2019s stated intention to preserve manufacturing capabilities domestically, a point at odds with regulators\u2019 concern about control and access.<\/p>\n
