On April 24, 2017, the European Commission authorized the Bolloré’s acquisition of de facto sole control over Vivendi. With a minority shareholding of only 26.4% without de jure veto rights on strategic business decisions, the Commission considered that this minority shareholder exercised de facto sole control over Vivendi on the basis of the following body of evidence: (i) it is the only industrial shareholder among financial shareholders, (ii) Mr. Bolloré is the Chairman of the Supervisory Board, which gives him influence on both the Supervisory Board and the Management Board, (iii) most proposals supported by Bolloré during past general meetings requiring simple majority had been approved, and (iv) Vivendi’s remaining shareholding structure is very scattered, and nothing indicates that a common interest brings together a blocking minority against Bolloré. This case recalls that even without veto rights, a minority shareholding can sometimes require prior antitrust approval if it confers de facto control.
