Actionable Insight • Neutral

Monitor for any subsequent amendments to this 13G for stake changes, or a potential conversion to a 13D if Bellevue's intent changes. The 10.6% position is large enough to be a meaningful holder, but the passive certification and institutional profile (Swiss asset manager) make an activist campaign unlikely.

Executive Summary

Bellevue Group AG, a Swiss asset manager, filed a Schedule 13G disclosing a 10.6% passive stake in Yarrow Bioscience (VYNE), representing 1,000,000 shares. This is a new filing by Bellevue, not an amendment, and the stake is based on 9,437,693 shares outstanding as of September 14, 2026, after an equity offering. The passive nature and institutional identity suggest a routine investment, not an activist precursor.
