The Pinault family has reached out to potential buyers of Puma after the German sports brand lost about half of its market value in the past year, according to people familiar with the matter.

The billionaire family, which owns a 29% stake in Frankfurt-listed Puma through Artemis, is working with advisers, possibly with a view to triggering a sale of the company, the people said, asking not to be identified because the deliberations are private.

They have reached out to prospective bidders including Anta Sports Products and Li Ning to gauge interest in buying Puma, the people said, adding they have also sounded out other sportswear firms in the U.S., as well as sovereign wealth funds in the Middle East.
