HARRISBURG — Nippon Steel and U.S. Steel said Wednesday that they have finalized their “historic partnership,” a year-and-a-half after the Japanese company first proposed its deal to buy the iconic American steelmaker for nearly $15 billion.

The "golden share" gives the U.S. government a level of control, but not a financial stake, in the Pittsburgh-based company.

A year and a half after a deal between Nippon Steel and U.S. Steel was announced, the two companies said they finalized their “historic partnership.”
