The European Commission imposed a fine of €110 million against the US company Facebook on May 18, 2017, following an investigation conducted in connection with Facebook’s takeover of WhatsApp in 2014. Facebook is sanctioned for having provided inaccurate information to the Commission declaring that it would not be able to combine the accounts of Facebook and WhatsApp users. The Commission’s attention was drawn to the fact that Facebook had announced the combination of the accounts shortly after the operation, and it turned out that Facebook knew when notifying this that it was technically possible. This sanction does not call into question the takeover authorization granted by the Commission but sends a strong signal to companies to dissuade them from providing inaccurate information to the Commission in connection with merger operations.
