Posco

What Posco does

POSCO is South Korea's largest integrated steelmaker, founded in 1968 and headquartered in Seoul, operating through a holding-company structure (POSCO Holdings Inc., NYSE: PKX; KRX: 005490) that controls wholly-owned subsidiaries including POSCO International (trading), POSCO E&C (construction), POSCO Future M (battery materials), POSCO DX (digital services), POSCO Steelion (steel processing), POSCO M-Tech (manufacturing solutions), and POSCO Air Solution (industrial gases). The company produces and sells flat steel, automotive steel sheets, electrical steel, and KR-certified naval steels through two primary integrated works — Pohang (energy steel) and Gwangyang (automotive and new mobility) — and completed Korea's largest electric arc furnace at Gwangyang in June 2026 (2.5 million tonnes annual capacity, ~KRW 600 billion / USD 396.7 million invested).

POSCO's business model is multi-vertical, combining traditional contract-based steel sales to industrial customers (Hyundai Motor Group, Volvo Construction Equipment, Korean Navy via HD Hyundai Heavy Industries) with vertically integrated adjacent businesses: POSCO Air Solution's high-purity rare gas plant supplies 52% of South Korea's semiconductor xenon/krypton/neon demand; POSCO Future M produces synthetic graphite anode materials for lithium-ion batteries; and the Sal de Oro lithium hydroxide project in Argentina achieved 25,000 tonnes/year commercial production in 2026. POSCO also pursues hydrogen-based steelmaking (HyREX technology co-developed with BHP, targeting 2030 commercialization), EV-oriented electrical steel, and green iron via partnerships with Cleveland-Cliffs, Hyundai Steel (Louisiana JV), and JSW Steel (India JV). Pricing is negotiated contract-by-contract with multi-year terms; the customer base spans automotive OEMs, semiconductor fabs, defense shipbuilders, and battery manufacturers globally.

POSCO's go-to-market relies on enterprise field sales to major industrial buyers, supplemented by joint ventures for geographic market access (JSW for India, Hyundai Steel for North America) and bilateral government forums (India-Korea Business Summit, Korea-Vietnam Business Forum). Beyond steel, POSCO derives strategic positioning from ESG credentials (MSCI A rating, World Benchmarking Alliance 'Just Transition' excellence, World Steel Association Sustainability Champion for five consecutive years) and a co-prosperity ecosystem with 480 SME partners receiving 926 transferred patents since 2017. Capital allocation is heavy toward decarbonization and adjacent vertical expansion, funded in part by ESG-linked instruments such as the $500 million green bond (January 2024, oversubscribed 8x).
