Insights
Soleus group holds a non-controlling, disclosed 416,599-share position in Biodesix.
The filing shows the position is held directly by Soleus Capital Master Fund, L.P., with voting and dispositive powers reported as shared at 416,599 shares. The percentage figure of 4.1% is tied to the issuer's reported outstanding share count of 10,108,580 as of April 29, 2026.
Because the position is under the 5% threshold and the filing is a Schedule 13G/A amendment, this is a passive disclosure of ownership; further filings would be required if the holdings or intent change.
Affiliated entities and an individual are named for regulatory clarity; disclaimers limit individual attribution.
The report lists Soleus Capital, LLC; Soleus Capital Group, LLC; Soleus Capital Management, L.P.; Soleus GP, LLC; and Guy Levy alongside the Master Fund, with an explicit disclaimer that these parties "disclaim beneficial ownership" except for Section 13(d) obligations. This preserves the Master Fund as the direct holder in the disclosure.
Stake attribution is important for proxy and notification rules; any change in shared/sole power or in the fund's intent would trigger different reporting obligations.

Schedule 13G/Aregulatory
"Amendment No. 1 to a Schedule 13G/A updating passive ownership"
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.
beneficial ownershipfinancial
"Amount beneficially owned: The information in rows 5 through 9 and 11"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
