INHIBRX BIOSCIENCES, INC. is a registered legal entity registered in United States under 6195284, and its current status with California Secretary of State — bizfile Online is active. The company was incorporated on 29 March 2024 and lists its registered address as United States. 5 shareholders are on record for INHIBRX BIOSCIENCES, INC., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from California Secretary of State — bizfile Online and was last updated on 25 September 2026.

Shareholders

5

Shareholders of INHIBRX BIOSCIENCES, INC.

Five shareholders are currently on record for INHIBRX BIOSCIENCES, 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 iShares Trust-iShares Russell 2000 ETF, holding 2.4% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 1%; the remaining 3 shareholders shown hold smaller stakes. 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.

Data availability

The register reports 8 shareholders in total, though only the top 5 by holding are shown in this view.
