NANOBIOTIX
NANOBIOTIX is a Public Limited Company registered in France under 44752160000034, and its current status with INPI (Institut National de la Propriété Industrielle) is active. The company was incorporated on 1 March 2003 and lists its registered address as PARIS, France. 2 shareholders are on record for NANOBIOTIX, 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 INPI (Institut National de la Propriété Industrielle) and was last updated on 9 September 2026.

Shareholders
2
Two shareholders are currently on record for NANOBIOTIX, held on the statuts (articles of association) and filed corporate acts, filed under the Code de commerce.
The largest of these is SPDR Portfolio Developed World ex-US ETF, holding 43.1% — the largest recorded stake — followed by SPDR (R) Idx Shares-SPDR (R) S&P (R) International Small Cap ETF at 10%.
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.

The Chief Clinical And Medical Affairs Officer & Chairman Of The Scientific Advisory Board of NANOBIOTIX on record is Leonard A. Farber M.d.; 5 officers are shown here, filed with INPI (Institut National de la Propriété Industrielle).
The register reports 57 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at NANOBIOTIX sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
NANOBIOTIX has no recorded parent company — it sits at the top of its own group structure, with 2 subsidiaries recorded beneath it across 3 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span France, United States, Germany jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
