Insights

Soleus group holds a near-10% stake via pooled vehicles; voting and disposition are shared across related entities.

The filing lists 4,354,501 shares (9.8%) tied to Guy Levy and affiliated Soleus entities, with shared voting/dispositive power across funds and manager entities. This structure is typical for investment managers consolidating economic exposure through funds.

Key dependencies include whether these holdings are passive under Schedule 13G rules and any future Section 13(d) obligations. Subsequent filings would show changes in voting position or transfers.

This amendment clarifies ownership counts and the outstanding-share basis; it does not announce transactions or changes in control.

The filing ties percentage calculations to the Form 10-Q cover’s 44,561,695 shares outstanding as of April 16, 2026. It lists per-entity counts such as 1,703,961 and 2,619,753, useful for tracking which legal entities hold economic exposure.

Watch for future amendments that would report purchases, dispositions, or a shift to Schedule 13D if intent to influence governance changes.

Schedule 13G/A regulatory
"Amendment No. 2 and beneficial ownership disclosure"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
