Sunrise Communications Ag
Sunrise Communications Ag is a Private limited company (Ltd.) registered in Switzerland under CHE103209608, and its current status with Zefix — Swiss Central Business Names Index is inactive. Its registered address on file is Glattpark (Opfikon), Switzerland. 5 shareholders are on record for Sunrise Communications 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 28 September 2026.

Shareholders
5
Five shareholders are currently on record for Sunrise Communications 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 Renaissance Technologies, LLC, holding 5.9% — the largest recorded stake — followed by DFA INVESTMENT DIMENSIONS GROUP INC-U.S. Small Cap Value Portfolio at 3.4%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 16 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.

The register reports 9 officers in total, including past appointments, though only the 5 most relevant records are shown here.

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
Sunrise Communications Ag has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 2 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 1 subsidiary spans Switzerland, Netherlands 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. 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.
