Posco Holdings, South Korea's Posco Group parent company, plans to sell its stake in Nippon Steel to optimize its asset portfolio. The shares, worth about 467 billion won, are marked for sale, though the timing and method are undecided. This aligns with Posco's strategy to streamline operations and improve financial efficiency.

The sale is part of a broader restructuring plan, including divesting non-core assets and boosting financial stability. 

Posco confirmed the decision was made with Nippon Steel, and their strategic partnership remains intact. This ends a 25-year equity relationship that began in 1999 with cross-holdings to strengthen ties.
