Shareholders
5
Five shareholders are currently on record for 89BIO, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is VANGUARD INDEX FUNDS-Vanguard Total Stock Market Index Fund, holding 3.9% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 2.5%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 8 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.
