Dongkuk Steel Q3 Operating Profit Rises 22% as AI Data Centre Steel Demand Expands

The Quick Take

• Dongkuk Steel posted Q3 operating profit of KRW 29.9 billion, up 22% year-on-year
• Revenue rose 21.2% year-on-year to KRW 932.3 billion on semiconductor and AI data centre steel demand
• Japan's September industrial production rose 2.2% month-on-month on automotive sector recovery
• Dongkuk's result slightly exceeded the KRW 24.4 billion consensus operating profit estimate

Dongkuk Steel's third-quarter operating profit of KRW 29.9 billion, a 22% year-on-year improvement, underscores how Korean steel manufacturers are capturing demand from the AI infrastructure build-out. The company attributed the improvement to higher sales of shaped steel products driven by semiconductor plant and AI data centre construction, sectors that require structural steel at scale. Revenue of KRW 932.3 billion also grew 21.2% year-on-year, beating consensus estimates, though net income fell 38% from the prior year as seasonal factors and financial costs weighed below the operating line.

Japan's simultaneous September industrial production increase of 2.2%, its first monthly rise in three months, adds a positive regional manufacturing signal. The automotive sector recovery was the primary driver, suggesting that supply chain normalisation in the auto industry is supporting output across the broader Northeast Asian manufacturing complex. For Korean steel companies supplying automotive sheet steel, Japanese production recovery signals improving demand from a key downstream sector, supporting order volumes into the fourth quarter.

The key watch point for Dongkuk Steel and Korean steel peers is whether AI data centre construction demand remains elevated through the first half of 2027, providing a structural demand floor beneath cyclical steel industry pressures. Japan's automotive production sustainability depends on continued semiconductor component availability, which remains the critical input constraint. The macro variable is Chinese steel export dumping: if Chinese overcapacity drives export volumes into Southeast Asia and compresses regional steel prices, Korean producers face margin headwinds despite strong AI-driven volume growth.
