Premerger Notification Program

The Hart-Scott-Rodino Act established the federal premerger notification program, which provides the FTC and the Department of Justice with information about large mergers and acquisitions before they occur.  The parties to certain proposed transactions must submit premerger notification to the FTC and DOJ.  Premerger notification involves completing an HSR Form, also called a “Notification and Report Form for Certain Mergers and Acquisitions,” with information about each company’s business.  The parties may not close their deal until the waiting period outlined in the HSR Act has passed, or the government has granted early termination of the waiting period.  For more information about the program, read our Introductory Guides.  The FTC administers the premerger notification program, and the staff of the Premerger Notification Office is available to answer questions about how and when to file.
