The steel industry just witnessed a seismic shift. On June 18th, Nippon Steel finalized its acquisition of US Steel, a deal valued at nearly $15 billion. This marks the end of an era for the American steel giant, whose shares ceased trading on the New York Stock Exchange (NYSE) at 8:25 a.m. ET that same day.

A formal notice confirmed the delisting, following the completion of the acquisition. The NYSE informed the Securities and Exchange Commission of the decision, bringing to a close the company’s more than century-long presence on the exchange; US Steel’s stock had been listed since 1901.

In a joint statement, both companies announced the successful closing of the deal. This massive acquisition sees Nippon Steel taking control of the struggling US Steel, signaling a potential reshaping of the global steel market. The long-term implications of this merger remain to be seen, but it’s undoubtedly a significant development in the industry.
