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.

  • Important Notice for the Delivery of HSR Filings:  The Constitution Center is subject to REAL ID security. REAL ID is a coordinated Department of Homeland Security effort by the states and the Federal Government to improve the reliability and accuracy of state-issued identification documents. Unfortunately, not all states currently produce REAL ID compliant identification, which may make it difficult for a visitor to enter the Constitution Center. New York is one of the non-compliant states and many delivery persons with New York IDs have been denied entry by the building guards.

    Delivery persons with non-compliant REAL IDs will not be allowed to deliver HSR filings to the 5th floor Premerger window. The Premerger Office does not have adequate staff to come to the loading dock to pick up filings, so please make sure all delivery persons have compliant IDs. Failure to do so may result in a delay in filing.
