U. S. Steel (NYSE: X) has closed on the purchase of POSCO-California Corporation (POSCAL)'s 50% partnership interest in USS-POSCO Industries (UPI), effective February 29, 2020. After a long, collaborative relationship, U.S.Steel and POSCAL concluded that ownership of UPI by a single group represents the best opportunity for UPI to continue operating effectively and serve its customers.
The January 23, 2020 purchase agreement regarding this transaction was previously disclosed in U.S.Steel's February 14, 2020 10-K filing. In the interim, the partners have been working together to ensure a smooth, constructive transition. In the near term, U. S. Steel plans to operate UPI as a separate entity.
