Insights

Institutional Ownership Analyst

Opaleye-related entities now clearly disclose a >10% stake in Alpha Cognition.

The filing shows 2,620,369 shares (12.03%) held jointly by Opaleye Management Inc., Opaleye, L.P., and James Silverman; 2,530,369 shares (11.62%) are shown for the Fund based on share counts.

Ownership is reported as shared voting and dispositive power, and the statement is a joint filing rather than an admission of beneficial ownership under Section 13. Future filings may update whether this position changes.

Corporate Governance Specialist

Shared voting/dispositive power implies adviser control over managed-account votes.

The disclosure clarifies roles: the Adviser advises the Fund and Mr. Silverman is the Adviser's controlling person. The filing reiterates that it should not be construed as admitting beneficial ownership under Section 13.

Watch for subsequent amendments or Form 13D/13G updates if voting arrangements or percentages change.

4 terms

Schedule 13G/A regulatory

"Amendment No. 5 Alpha Cognition Inc. 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.

beneficial ownership financial

"Amount beneficially owned: 2,620,369.00"

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.
