Shareholders of DUCOMMUN INCORPORATED
Seven shareholders are currently on record for DUCOMMUN INCORPORATED, 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 9.1% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 3.8%; the remaining 5 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.

Data availability
Those 13 subsidiaries span United States, United Kingdom 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. Four of the 13 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
