The Hermès family holding company that owns a controlling stake in the brand is H51.
H51 was created by members of the Hermès family to coordinate their ownership of Hermès International. The arrangement became especially important after luxury-goods group LVMH disclosed a large position in Hermès shares in 2010. By pooling family interests, H51 helped preserve family control over the company and reduce the likelihood of individual shareholders selling independently.
The name refers to the family’s holding structure rather than to a Hermès product or collection. Hermès remains publicly traded on Euronext Paris, but the family’s combined ownership gives it decisive influence over the business.
H51 is often mixed up with product names such as H24, the men’s fragrance launched in 2021. H24 is a perfume line; H51 is a corporate ownership vehicle.
