Nippon Steel Corp. has communicated its spending commitments for its bid to acquire United States Steel Corp. after discussions with United Steelworkers leaders.

The Japanese company has outlined its plans in a letter to US Steel employees, providing details on how a previously announced $1.4 billion investment in US mills will be allocated. This investment amount does not include maintenance and depreciation costs, highlighting Nippon Steel's focus on improving operations and gaining support from workers and local politicians.

This move is part of Nippon Steel's strategy to strengthen its position in the competitive US steel market as it works towards finalizing the acquisition of the Pittsburgh-based steelmaker.
