Ubisoft is a French video game publisher and distributor, employing 14,800 people and generating revenues of ¤1.7 billion in 2018. The company was founded in 1986 by the five Guillemot brothers, who are still in charge as shareholders, directors and members of the management team. Independence is one of the company's fundamental values. However, at the end of 2015, the Vivendi group acquired a stake in Ubisoft and embarked on a gradual share purchase operation to the point of owning more than 25% of the shares at the end of 2017, thus becoming the largest shareholder and raising fears of a takeover bid. Ubisoft defended itself by using several means: a media communication strategy, locking the Board of Directors to prevent the entry of a Vivendi representative, calling for the support of current shareholders, seeking new investors, increasing the family's stake in the company, repurchasing its own shares by the company, mobilizing employees, etc. After more than two years of regular increases in its stake in Ubisoft, Vivendi withdrew and sold most of its shares in March 2018, then completely exited the capital in March 2019.
