Sonova Holding Ag
Sonova Holding Ag is a Private limited company (Ltd.) registered in Switzerland under CHE100818478, and its current status with Zefix — Swiss Central Business Names Index is active. The company was incorporated on 16 July 1985 and lists its registered address as Stäfa, Switzerland. 5 shareholders are on record for Sonova Holding Ag, 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 22 September 2026.

Shareholders
5
Five shareholders are currently on record for Sonova Holding Ag, 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 HARDING LOEVNER Fd.S INC-Harding Loevner Intl Eqy. PORT., holding 3.9% — the largest recorded stake — followed by T. ROWE PRICE Intl Fd.S, INC.-T. Rowe Price Intl Stock Fd. at 2.5%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 15 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.

Officers
5
The Chief Executive Officer of Sonova Holding Ag on record is Kaldowski Arnd; 5 officers are shown here, filed with Zefix — Swiss Central Business Names Index.
The register reports 24 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Sonova Holding Ag 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
Sonova Holding Ag has no recorded parent company — it sits at the top of its own group structure, with 39 subsidiaries recorded beneath it across 23 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 39 subsidiaries span Switzerland, Belgium, United States, Sweden, Poland, New Zealand, and 17 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. Nine of the 39 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
