Rhea-AI Filing Summary

Marc Maurer reports beneficial ownership of 2,835,633 Class A ordinary shares of On Holding AG, representing 0.9% of the reported 327,157,741 Class A-equivalent shares. The total ownership figure includes 618,358 Class A ordinary shares underlying vested options and option awards. All ownership figures are presented as of June 30, 2025.

Insights

Financial Analyst

TL;DR: Minor personal stake disclosed — 2.84M shares (0.9%), including 618k vested options; not a material ownership change.

The Schedule 13G reports that Marc Maurer beneficially owns 2,835,633 Class A ordinary shares of On Holding AG, equivalent to 0.9% of the 327,157,741 Class A-equivalent share base used in the filing. The filing specifies sole voting and dispositive power over these shares and notes that 618,358 shares are from vested options and awards. From an investor-impact perspective, this level of ownership is below common materiality thresholds and is unlikely to affect governance or drive strategic changes.

Corporate Governance Expert

TL;DR: Disclosure is routine; ownership is sub-5% with sole control of reported shares, so governance impact appears limited.

The statement identifies Mr. Maurer as the reporting person with citizenship in Switzerland and confirms sole voting and dispositive authority over the disclosed 2,835,633 shares. The inclusion of 618,358 vested-option shares is explicitly stated. Because the position represents 0.9% of the issuer's reported Class A-equivalent shares, the filing reads as a routine beneficial-ownership disclosure rather than a governance-changing stake.
