On Holding AG (traded on the New York Stock Exchange under the ticker ONON) is a publicly traded corporation, meaning its ownership is distributed among a vast array of institutional investment management firms, global mutual funds, retail shareholders, and corporate insiders. Key stakeholders include its founding members, early-stage venture backers, and prominent institutional asset managers who hold substantial blocks of common stock. Furthermore, elite athletic partners—such as tennis champion Roger Federer, who owns a significant equity stake—are famously associated with the brand's ownership and advisory structure, while daily trading on the public exchange causes ownership percentages to fluctuate continuously.
