Summary

Companies controlled by a foreign government must not merge with, buy, or take over certain U.S. businesses. The rule covers U.S. companies that either are working on a Defense Department contract or an Energy Department national security contract that needs access to specially restricted information, or that received more than $500,000,000 in Defense prime contracts or more than $500,000,000 in Energy national-security prime contracts in the previous fiscal year. The ban does not apply if the deal is not suspended or blocked under section 4565. “Entity controlled by a foreign government” means an organization or person owned, controlled, or acting for a foreign government as the President decides. “Proscribed category of information” means the kinds of sensitive information the Secretaries of Defense or Energy say cannot be shared with such entities; the departments will define those categories in rules.
