Louis Hachette Group S.A. is a global media, publishing, and retail conglomerate headquartered in Paris, France. The company was established as an independent publicly traded entity in December 2024 following its spin-off from Vivendi SE.

The remainder of the revenue comes from Lagardère Live Entertainment and other media activities. Geographically, the company has a highly diversified footprint, with significant operations in France, the broader European Union, and the United States.
