Financière Agache SA is an investment holding company based in Paris that is the controlling shareholder of Dior and LVMH.

The origins of Financière Agache can be traced back to Agache-Willot-Boussac, a French group that dealt in retailing, fashion and manufacturing.

[2] In 1984, Bernard Arnault, then a young real estate developer had just returned to France from the United States and had heard that the French government was set to choose someone to take over Agache-Willot-Boussac.

During his time in New York, Arnault was neighbour to John Kluge who made billions by taking his company Metromedia private and then liquidating it and had also watched the success KKR had with its leveraged buyouts.

[2][3] Using Financière Agache as a platform, Arnault led an aggressive expansion to create the world's biggest luxury conglomerate.

[7] In July 2022, Arnault changed the legal structure of Agache from a Societas Europaea to a joint-stock partnership to ensure family control over LVMH in the long term.
