DIAMOND OFFSHORE DRILLING, INC. is a registered legal entity registered in United States under 0009744806, and its current status with Texas Secretary of State — SOSDirect is active. The company was incorporated on 31 July 2026 and lists its registered address as HOUSTON, United States. 5 shareholders are on record for DIAMOND OFFSHORE DRILLING, INC., 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 Texas Secretary of State — SOSDirect and was last updated on 22 September 2026.

Shareholders

5

Five shareholders are currently on record for DIAMOND OFFSHORE DRILLING, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.

The largest of these is Contrarius Investment Management Limited, holding 12.1% — the largest recorded stake — followed by KGH Ltd at 10.9%; the remaining 3 shareholders shown hold smaller stakes.

The register reports 20 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.

Group Structure

DIAMOND OFFSHORE DRILLING, INC. sits 2 levels below its ultimate parent, The Depository Trust & Clearing Corporation, registered in United States. 5 subsidiaries are recorded beneath it, across 4 jurisdictions. The full chain up to The Depository Trust & Clearing Corporation is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by DIAMOND OFFSHORE DRILLING, INC.'s own shareholder record. 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 5 subsidiaries span United States, Cayman Islands, Mexico, Bermuda 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. Three of the 5 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
