Addex Therapeutics Ltd
Addex Therapeutics Ltd is a Private limited company (Ltd.) registered in Switzerland under CHE113514094, and its current status with Zefix — Swiss Central Business Names Index is active. The company was incorporated on 19 March 2007 and lists its registered address as Plan-Les-Ouates, Switzerland. 2 shareholders are on record for Addex Therapeutics Ltd, 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 Zefix — Swiss Central Business Names Index and was last updated on 28 September 2026.

Shareholders
2
Two shareholders are currently on record for Addex Therapeutics Ltd, reflecting the Aktienbuch (share register) maintained under Article 686 of the Swiss Code of Obligations rather than a public filing.
The largest of these is UBS Group AG, holding 50.3% — a majority holding — followed by SBI Securities Co., Ltd. at 0.3%.
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.
| Shareholder | Type | Holding | Source Document |
|---|---|---|---|
| UBS Group AG | 50.3% | Zefix — Swiss Central Business Names Index | |
| SBI Securities Co., Ltd. | 0.3% | Zefix — Swiss Central Business Names Index |
Officers
4
Four officers are currently on record for Addex Therapeutics Ltd, filed with Zefix — Swiss Central Business Names Index. Timothy Mark Dyer serves as Co-founder, Ceo & Director; Roger G. Mills M.d. serves as Chief Medical Officer & Director; Lenaic Teyssedou serves as Head Of Finance; Mikhail Kalinichev Ph.d. serves as Head Of Translational Science.
Management authority at Addex Therapeutics Ltd 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
Addex Therapeutics Ltd has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 1 jurisdiction. 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 1 subsidiary spans Switzerland jurisdiction, 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. One of the 1 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
