On Holding slides as CEO steps down, founders take over May 1
On Holding AG shares fell as investors reacted to a leadership overhaul that will replace CEO Martin Hoffmann with co-founders David Allemann and Caspar Coppetti as co-CEOs effective May 1, 2026. The transition also includes a CFO handoff to Frank Sluis and a planned May 28, 2026 AGM vote to convert Hoffmann’s high-vote Class B shares into Class A shares.
1) What’s moving ONON today
On Holding AG (ONON) is trading lower as the market digests a sweeping management transition: co-founders David Allemann and Caspar Coppetti are set to become co-CEOs on May 1, 2026, while current CEO Martin Hoffmann plans to step down. The reshuffle adds another layer of uncertainty for investors already focused on execution risk, continuity, and the pace of global expansion through the rest of 2026. (tipranks.com)
2) Leadership and governance details investors are focusing on
Beyond the CEO change, investors are also watching two related mechanics. First, CFO responsibilities are expected to transition to incoming CFO Frank Sluis starting May 1, 2026. Second, the company has indicated that Hoffmann’s Class B voting shares are slated to be proposed for conversion into Class A ordinary shares at the annual general meeting on May 28, 2026—an element the market is treating as a potential governance and supply/overhang headline alongside the executive exits and promotions.

3) Why the stock is reacting now
Even when founders remain deeply involved, sudden C-suite changes can pressure the stock as investors re-underwrite leadership credibility, decision speed, and accountability—especially when paired with an imminent finance leadership transition and a specific, dated governance event (the May 28 AGM conversion vote). With ONON already volatile around recent company updates, today’s move reflects risk-off positioning tied to the transition timeline rather than a single product or demand datapoint. (tipranks.com)
4) What to watch next
Key dates now matter. May 1, 2026 is the handover to co-CEOs and the start date for the new CFO, and May 28, 2026 is the AGM where the Class B-to-Class A conversion proposal is expected to be put to shareholders. Traders will be watching for follow-through analyst actions, any additional organizational changes, and management communication that clarifies who owns operational decisions day-to-day under the new co-CEO structure.
