The partnership between US Steel and Nippon Steel has reached a new phase, with an agreement on US national security guarantees, in addition to the so-called "golden share" advantage obtained by President Donald Trump's administration.
On Friday evening, Trump signed an executive order approving the partnership, bringing an end to the long-running saga over foreign ownership of a key national asset which began in December 2023, when US Steel and Nippon Steel announced plans for a $14.9 billion merger.
