Shareholders of AMKOR TECHNOLOGY, INC.
Three shareholders are currently on record for AMKOR TECHNOLOGY, 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 17% — the largest recorded stake — followed by VANGUARD WORLD FUND-Vanguard Information Technology Index Fund at 3.3%; 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.

Data availability
Those 10 subsidiaries span United States, Germany, Japan, Portugal, China, Malaysia, and 1 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. Two of the 10 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
