Transocean Ltd.
Transocean Ltd. is a Private limited company (Ltd.) registered in Switzerland under CHE114461224, and its current status with Zefix — Swiss Central Business Names Index is active. The company was incorporated on 18 August 2008 and lists its registered address as Steinhausen, Switzerland. 4 shareholders are on record for Transocean 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 22 September 2026.

Shareholders
4
Four shareholders are currently on record for Transocean 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 Vanguard Group Inc, holding 17.6% — the largest recorded stake — followed by Pilgrim Global Advisors LLC at 3.1%; the remaining 2 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.
| Shareholder | Type | Holding | Source Document |

| Pilgrim Global Advisors LLC | 3.1% | Zefix — Swiss Central Business Names Index | |

Officers
5
The Executive Chair of Transocean Ltd. on record is Jeremy D. Thigpen; 5 officers are shown here, filed with Zefix — Swiss Central Business Names Index.
The register reports 20 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Transocean 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
Transocean Ltd. has no recorded parent company — it sits at the top of its own group structure, with 127 subsidiaries recorded beneath it across 16 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 127 subsidiaries span Switzerland, Bermuda, Cayman Islands, Marshall Islands, United States, Egypt, and 10 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. 17 of the 127 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
