POSCO Holdings is a Korean holding company whose core asset is POSCO, one of the largest fully integrated steel producers in the world. POSCO manufactures cold rolled and hot rolled products, stainless steel, plates, wire rods, and silicon steel sheets, selling to industrial customers in Korea and export markets across Asia, Europe, and North America. These products serve automotive, shipbuilding, construction, appliance, and industrial machinery customers. Korea is POSCO's most important market, where POSCO holds dominant domestic positions across all major product categories. The Steel segment accounts for roughly 54% of consolidated revenue, followed by Trading (~34%, through POSCO INTERNATIONAL, which trades steel, raw materials, and agricultural goods, and operates LNG power generation in Korea), Construction (~8%, through POSCO E&C), and Rechargeable Battery Materials (~3%, through POSCO Future M). POSCO earns its margin by selling steel above its cost of production, with profitability driven by the spread between steel selling prices and raw material costs — primarily iron ore and coking coal imported from Australia, Brazil, Canada, and the U.S. Beyond its core steel business, POSCO Holdings is pursuing two growth vectors: overseas steel expansion, with JV projects in India and the U.S., and EV battery materials vertical integration, building a supply chain from lithium mining through cathode and anode manufacturing via POSCO Future M.
