Shareholders
5
Five shareholders are currently on record for PROFUSA, 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 UBS Group AG, holding 71.5% — a majority holding — followed by VANGUARD INDEX FUNDS-Vanguard Extended Market Index Fund at 19%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 7 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.
