Officers
5
The Ceo & Representative Director of Posco currently on record is In-hwa Chang; five officers are currently on record for Posco, filed with Supreme Court Internet Registry (IROS).
The register reports 15 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Posco sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Posco has no recorded parent company — it sits at the top of its own group structure, with 60 subsidiaries recorded beneath it across 22 jurisdictions. 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 60 subsidiaries span South Korea, China, Hong Kong, Uruguay, Italy, Indonesia, and 16 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. 13 of the 60 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
