Nippon Steel makes transition to direct ownership in U. S. Steel Košice

USSK to be positioned as a core operating hub in Europe in Nippon Steel’s global strategy.

Nippon Steel has decided to transition U. S. Steel Košice (USSK), a Slovakia-based wholly-owned subsidiary of U. S. Steel, to direct ownership by Nippon Steel (making it a wholly-owned subsidiary of Nippon Steel). The transition to the new structure is scheduled to take place on October 1, 2026, and on the same day, the company name will be changed to Nippon Steel Slovakia s.r.o. (NSSK).
By direct ownership of USSK, Nippon Steel will establish the company as a core hub for its European operations in its global strategy, and become more directly involved in enhancing the profitability and accelerating the growth of its European business, the company said.
According to Nippon Steel, the European steel market is the third largest in the world after China and the United States, and is a mature market with large demand for high-grade steel, for which Nippon Steel can leverage its state-ofthe-art product technologies. Especially in Central and Eastern Europe, economic growth is expected to continue and demand for high-grade steel is expected to increase driven by customers’ relocation of manufacturing bases.
Since commencing operations in 1965, USSK has contributed to the development of the European manufacturing industry by supplying high-quality steel products to a wide range of sectors, including automotive, electrical, packaging, energy, and construction, primarily in Central and Eastern Europe.
Nippon Steel has been working since its acquisition of U. S. Steel in 2025, on enhancing USSK’s competitiveness .
