Shareholders

Three shareholders are currently on record for VANTAGE DEEPWATER 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 Blackrock Funds II-Blackrock Strategic Income Opportunities Portfolio, holding 81.7% — a majority holding — followed by BlackRock Master Total Return Portfolio of Master Bond LLC at 16.3%; the remaining 1 shareholder shown holds 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.

The current roles shown are Ihab Toma as Chief Executive Officer and, in a separately filed record, as President; Douglas Stewart as Secretary and Director; Linda Ibrahim as Vice President; and Douglas Halkett as Vice President.
Ihab Toma has served as Chief Executive Officer of the wider Vantage Drilling International group since August 2016, and Douglas Halkett previously served as that group’s Chief Operating Officer from 2008, according to the group’s official website. These externally confirmed group-level roles are consistent with, but distinct from, their recorded positions at Vantage Deepwater Drilling, Inc., and appointment or resignation dates for the individual officer records at this entity are not disclosed.
Nationality is not disclosed for any officer in the available records. The registry lists a correspondence country and region of “US” for each officer; this reflects a correspondence-address field only and does not indicate nationality or country of residence, neither of which is officially disclosed. The available officer information should be treated as current only, since historical resigned or removed appointments are not shown, and as partial, since only five of the nine total officer records held were returned in the reviewed data.

Group Structure
Vantage Deepwater Drilling, Inc. is not an independent company. SEC subsidiary exhibits filed in connection with the Vantage Drilling corporate group between 2012 and 2023 list it among the group’s entities, with the most recent such filing reviewed dated 2023. Zavia’s registry data places Vantage Deepwater Drilling, Inc. beneath an ultimate parent recorded as Vantage Drilling International, alongside numerous affiliated group entities in the Cayman Islands, Bermuda, Malaysia, Indonesia and India. Ownership and voting percentages between these entities are not disclosed in the available filings or registry data, so no relationship more specific than group affiliation can be confirmed for most of them.
A material change took place above this level of the structure on 26 June 2026, when Eldorado Drilling Limited, a Cayman Islands private company, completed its acquisition of Vantage Drilling International Ltd., a Bermuda exempted company, by way of merger. Vantage Drilling International Ltd. survived the merger as an indirect subsidiary of Eldorado Drilling Limited, according to the companies’ joint announcement of completion. Whether Vantage Deepwater Drilling, Inc. remained part of the Vantage Drilling International structure at the time of, or following, that transaction has not been independently confirmed.
The available corporate-linkage information for Vantage Deepwater Drilling, Inc. is best described as partial: its broad group affiliation is documented across more than a decade of filings, but its immediate parent entity, ownership percentages and current group membership following the 2026 Eldorado transaction are not confirmed.
