Swiss sportswear company On Holding has appointed Frank Sluis as its new Chief Financial Officer, effective May 1, 2026. Sluis joins the company from retail giant Ahold Delhaize, where he served as CFO for Europe and Indonesia since 2021.
The appointment comes as On continues its rapid global expansion. Sluis brings more than 25 years of experience at major consumer businesses, including finance leadership roles at Reckitt Benckiser and Unilever. At Ahold Delhaize, he led an international finance, procurement, and sourcing organization of approximately 800 professionals.

The move follows a period of transition for On’s leadership. Martin Hoffmann, who has served as both sole CEO and CFO since last year, will hand over financial responsibilities to Sluis in May. This change allows Hoffmann to focus exclusively on his role as CEO as the company pursues its global “premium positioning” strategy.
Caspar Coppetti, Co-Founder and Executive Co-Chairman of On Holding, noted that Sluis was selected for his strategic vision and leadership: “Frank stood out for his personal drive that will match our pace from day one, his credibility as a strategic partner to the Board and the CEO, and his proven ability to align long-term vision and financial leadership.”
The bottom line: On is entering its next phase of growth, where strong financial leadership is as critical as brand equity.
