MERSEN
MERSEN is a Public Limited Company registered in France under 57206033300240, and its current status with INPI (Institut National de la Propriété Industrielle) is active. The company was incorporated on 1 December 1980 and lists its registered address as COURBEVOIE, France. 5 shareholders are on record for MERSEN, 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 23 September 2026.

The largest of these is Invesco Global Opportunities Fund, holding 23.6% — the largest recorded stake — followed by DFA International Small Cap Value Portfolio at 8.5%; 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.

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.

Data availability
Those 39 subsidiaries span France, United States, Canada, United Kingdom, Netherlands, South Africa, and 16 more 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. 11 of the 39 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
