On Holding AG announced that Frank Sluis will join the Zurich-based premium sportswear maker as Chief Financial Officer effective May 1, 2026. Sluis brings more than 25 years of finance leadership in global consumer businesses, most recently serving since 2021 as CFO for Europe & Indonesia at Ahold Delhaize, where he oversaw financial operations for over €30 billion in annual net sales and led an 800-member international finance, procurement and sourcing organization. His prior roles include senior finance positions at Reckitt Benckiser and Unilever, equipping him with deep expertise in consumer behavior and brand building. Sluis will succeed Martin Hoffmann—who will continue to oversee the finance organization through the handover—allowing Hoffmann to focus solely on his expanded CEO responsibilities. Co-Founder Caspar Coppetti noted that Sluis’s strategic alignment with On’s growth vision and proven ability to scale international operations made him the ideal choice to support the company’s rapid global expansion.
