On January 2, 2026, President Donald J. Trump issued an order prohibiting HieFo Corporation from acquiring certain assets of Emcore Corporation.

This decision is based on credible evidence suggesting that the acquisition could pose a potential threat to U.S. national security. Consequently, HieFo is required to divest all interests in these assets within a specified timeline to ensure compliance with the order.

The order specifies detailed steps for HieFo and its affiliates regarding the divestment process, including a prohibition on accessing non-public technical information associated with the Emcore assets until the divestment is complete. The Committee on Foreign Investment in the United States (CFIUS) is empowered to enforce compliance with this order, including auditing rights to ensure that all necessary actions are taken. HieFo must also provide weekly certifications to CFIUS regarding its compliance status and efforts to meet the order’s requirements.

In summary, the President’s action reflects a stringent approach to foreign acquisitions involving sensitive technology and assets, particularly when national security is at stake. The order not only prevents HieFo from completing the acquisition but also establishes strict guidelines for how the divestment should be conducted and monitored by relevant U.S. authorities. This initiative underscores the government’s proactive measures to protect national interests in the current global landscape.
