Bernard Arnault's LVMH houses 70 luxury brands from Louis Vuitton to Hennessy to Dom Perignon, all controlled by family parent company Groupe Arnault. By the 1980s and '90s, Arnault, who started out as a civil engineer, had assumed control of the family business and proceeded to buy high-end fashion house Christian Dior, reviving it from the brink of bankruptcy. Like most LVMH brands today, Dior once again thrives as an industry standard bearer, helping the firm haul in a record $33 billion in revenue in 2014.
This year, the French chairman and CEO is joining US-based private-equity firm Catterton to form an investment firm with a consumer focus. The new firm, to be named L Catterton, is targeting $12 billion in assets under management and will be 40% owned by LVMH and Groupe Arnault.
