The French media group Vivendi wants to take over its competitor Lagardère. Vivendi has already secured more than 25 million shares in Lagardère’s major shareholder Amber Capital, according to a press release. The magazine belongs to Lagardère Paris Match and the radio station Europe 1. A takeover by Vivendi would create one of the largest media groups in Europe. The price of the Lagardère share jumped on Thursday morning by more than 21 percent to 23.62 euros. For Vivendi shares, however, it went down by 1.5 percent. If authorities approve the deal with Amber, Vivendi’s stake in Lagardère would rise to more than 30 percent.
