The blocking of HieFo Corporation's acquisition of Oracle Corporation's assets by Donald Trump signals increased scrutiny on foreign investments in critical technology sectors, particularly those involving China. This action could lead to a decrease in foreign direct investment in the United States' technology sector, especially from Chinese entities, and may impact the stock prices of companies involved in similar cross-border deals.
President Donald Trump issued an executive order blocking HieFo Corporation's acquisition of semiconductor assets from Oracle Corporation, citing national security concerns. The transaction, finalized in 2024 for $2.92 million, involved Oracle Corporation's New Jersey chip manufacturing operations and indium phosphide wafer production facilities. HieFo Corporation, a Delaware-registered entity, is controlled by a Chinese national. The United States — Committee on Foreign Investment in the United States identified national security risks related to potential access to Oracle Corporation's intellectual property and the potential diversion of indium phosphide chips. This move is part of the United States' broader efforts to restrict China's access to advanced semiconductor technologies. HieFo Corporation is required to divest the acquired assets within 180 days.
