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.

To submit an HSR filing via Accellion, fill out the online form.

  • 09-16-20 UPDATE: Please note that for all electronic HSR submissions, we require that submitted PDFs have searchable text. That is, the PNO and DOJ must be able to search the document, and select, copy and paste text from the PDFs directly into our Premerger database. Text in a PDF that’s obtained from an image file may not be able to be selected and copied, resulting in a longer processing time by the PNO and potentially delaying our review. Please make sure that all text is searchable and able to be selected and copied before submission.  (09/16/20)
