After over a year and a half of back and forth, the deal between U.S. Steel and Nippon is done.

Nippon Steel and United States Steel Corporation announced Wednesday morning that they have finalized their historic partnership.

In a statement, it said together, Nippon Steel and U. S. Steel will be a world-leading steelmaker, with best-in-class technologies and manufacturing capabilities. The partnership will protect and create more than 100,000 jobs through unprecedented massive investments in steelmaking in the United States that will be unleashed across U. S. Steel’s footprints, including in Pennsylvania, Indiana, Arkansas, Minnesota and Alabama.

This partnership ensures that U. S. Steel will retain its iconic name and headquarters in Pittsburgh, Pennsylvania, and that it will continue to be mined, melted, and made in America for generations to come.

The companies have also entered into a National Security Agreement with the U.S Government, and U. S. Steel will issue a Golden Share to the U.S. Government.

This means the government will have certain rights, like consenting to matters related to reductions in capital investments or changing the name.

Other highlights, per the companies:

1. Nippon will invest $11 billion dollars by 2028.
2. A majority of the members of the U.S. Steel Board will be U.S. citizens.
3. Nippon will not prohibit U.S. Steel’s ability from pursuing trade action under U.S. law.

The United Steelworkers had opposed the deal. So had President Biden. When he was a presidential candidate, President Trump had also opposed an outright acquisition.
