Shareholders
5
Five shareholders are currently on record for GRAPHITE 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 EcoR1 Capital, LLC, holding 28% — the largest recorded stake — followed by Samsara BioCapital, LLC at 27.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 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.
