Insights

Equity Capital Markets Analyst

Holders report a passive sub-5% position with shared voting/dispositive power.

The filing shows an aggregate beneficial position of 31,720,278 shares, equal to 4.95% based on an issuer-stated outstanding share count of 640,544,661 as of February 20, 2026. The schedule is styled as a joint filing covering the adviser entity and related fund.

Because the reported stake is below 5.00%, the filing is consistent with passive reporting status; subsequent disclosures would be required only if ownership or classification changes.

Corporate Governance Specialist

Shared voting and dispositive power is disclosed, and the filing names the controlling entity.

The cover page and Item 4 state shared voting power and shared dispositive power of 31,720,278 shares. Item 7 identifies Deep Track Capital, LP as the relevant entity for which Mr. Kroin may be considered a control person.

Stake classification as "Ownership of 5 percent or less of a class" is explicit; any future reclassification or increases above 5.00% would require an amended filing.

4 terms

beneficially owned regulatory

"Amount beneficially owned: 31,720,278"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

shared dispositive power regulatory

"Shared Dispositive Power 31,720,278.00"

Schedule 13G/A regulatory

"(Amendment No. 3 ) Geron Corp 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.
