Shareholders
5
Five shareholders are currently on record for GRI Bio, Inc., reflecting the stock ledger kept by the company under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is DRW Securities, LLC, holding 60.6% — a majority holding — followed by VANGUARD INDEX FUNDS-Vanguard Extended Market Index Fund at 10.2%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 9 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
