"Amendment No. 1 ) enVVeno Medical Corporation Common Stock"
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.
Shared dispositive powerfinancial

Beneficial ownershipregulatory
"Amount beneficially owned: Kingdon Capital Management, L.L.C. - 36,166"
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.
Kingdon-affiliated filers report beneficial ownership of 36,166 shares, representing 5.5% of the common stock. The filing lists shared voting and dispositive power for that share count.
Which Kingdon entities are named in the Schedule 13G/A?
Kingdon Capital Management, L.L.C., M. Kingdon Offshore Master Fund, L.P., Kingdon GP, LLC and Mark Kingdon are listed with the same reported share count and ownership percentage.
Does the filing state who actually owns the reported securities?
The filing states the securities are directly owned by advisory clients of Kingdon Capital Management, L.L.C., and that reporting persons disclaim beneficial ownership except to their pecuniary interest.
When was the Schedule 13G/A executed and who signed it?
The signatures show the filing was executed on 05/15/2026, signed by Richard Weinstein and Mark Kingdon in their listed capacities.
