How to notify a merger

As the business world evolves, your strategy evolves with it!

Proposed merger, take-over, joint venture creation: these transactions must all be referred to the Autorité de la concurrence if they are above a certain size.

How do you do this? This is the procedure you should follow to notify your merger.

Pre-notification phase

Before a company formally notifies a merger, it may, if it so wishes, contact the Autorité informally. It can then discuss the feasibility of its plans with the Mergers Unit and make any necessary advance arrangements in the case of a complex merger, and also minimise the risk of submitting an incomplete file at the time of notification.

To send a pre-notification or for any preliminary questions, please contact the Mergers Unit

by email or by telephone on +33 (0)1 55 04 01 72.

    Who is responsible for notification?

    • In the case of a take-over, it is the company acquiring control that notifies the transaction.
    • In the case of a merger, it is the merging companies that notify the transaction.
    • In the case of a joint venture creation, it is the companies creating the joint venture that notify the transaction.

    Notification desk

    Notification by mail

    Notifications of proposed mergers can be sent to the Autorité by registered letter with acknowledgement of receipt or can be deposited at the following address:

    Autorité de la concurrence
    Chef du service des concentrations
    11, rue de l'Echelle
    F–75001 Paris (France)

    Notifications can be deposited on working days between 9 am and 7 pm.

    When they are received or deposited, notification files are stamped with the date when they reached the Autorité. The date stamp and acknowledgement of receipt do not constitute registration.
