Shareholders of OCEANEERING INTERNATIONAL, INC.
Five shareholders are currently on record for OCEANEERING INTERNATIONAL, 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 Vanguard Group Inc, holding 14.8% — the largest recorded stake — followed by Brown Advisory Inc. at 7%; the remaining 3 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.

Those 21 subsidiaries span United States, Singapore, Nigeria, Luxembourg, Norway, Barbados, and 6 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. Three of the 21 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
