Nippon Steel and U.S. Steel: That Blast(ed) Furnace

At the beginning of December, it was announced that United States (U.S.) Steel, a subsidiary of Japan’s Nippon Steel, would restart a blast furnace, one of two furnaces idled and scheduled for shutdown in the US state of Illinois.  According to U.S. Steel (a refrain also echoed by its parent Nippon Steel), it opted to restart the blast furnace because of improved demand, an intriguing “defense” given that the US government, which has a “golden share” in U.S. Steel (which is elaborated below), rejected the furnace shutdown 3 months before.[1]  This episode seemed to validate the reservations of those who that forecast Washington’s golden share would result in it meddling in U.S. Steel decisions contrary to Nippon Steel wishes.  From the start, though, Nippon Steel has been confident, with its Chairman and CEO telling a news conference in June that his company was “‘fully satisfied with the agreement’” it struck with the U.S.[2]

By way of background, Nippon Steel, Japan’s largest steelmaker, completed its $14.9 billion buyout of U.S. Steel in June 2025 after an 18-month battle full of ups and downs and American White House flip-flops resulting from union pressures and then President Joseph Biden and president candidate Donald Trump’s quest to secure Pennsylvania, a key state in the 2024 campaign.  Nippon Steel’s buyout attempt initially was blocked by former President Biden, but eventually was approved by current President Trump after the conclusion of a “national security agreement.”  Pursuant to the agreement, the U.S. government obtained the aforementioned golden share.  This gave it the ability to block any move of U.S. Steel’s headquarters, any change in the firm’s name, any shift of production or jobs outside the U.S., plant closings, and more.  The deal also ensured an American CEO, a Board of Directors with a majority of U.S. citizens including one appointed and two approved by Washington.[3]  Despite these major concessions, the Chairman and CEO of Nippon Steel felt confident enough to opine at the aforenoted news conference that “‘We have secured the necessary management flexibility and profitability essential for business investment, and we recognize this agreement as fully satisfactory.’”[4]

The deal, which makes Nippon Steel the world’s fourth largest steelmaker, committed the firm to make roughly $11 billion in investments (taking the total value of its purchase to $25 billion).  In concept, the deal has several advantages for the firm beyond putting it into the top ranks of steelmakers.  It helps it jump high U.S. steel tariff walls (which also protect its U.S. operations against foreign competition), allows it to access U.S. iron ore and relatively cheaper energy costs, gives it a mechanism for tapping growing U.S. markets for steel in areas like infrastructure and electric vehicles, and positions it, more generally, to profit from U.S. economic growth.  Apparently, the leadership of Nippon Steel believe the acquisition will allow it to “counter China,” too.[5]  To deepen and expand its presence in the U.S. as well as meet its investment obligations pursuant to the terms of the deal, Nippon Steel plans to, among other things, renovate its largest blast furnace in Indiana, construct new facilities in Pennsylvania for processing steel slag, and build new production facilities that make steel geared for transformers.[6]

Ignoring Nippon Steel’s reportedly unimpressive track record as an acquiror, it remains to be seen if its acquisition will deliver the expected outcomes.  U.S. economic growth appears under pressure.  EVs purchases and public infrastructure construction have slowed due to Washington’s opposition in the former case and indifference in the latter.  The construction of new plants may encounter more bumps than anticipated.  Steel tariffs may drop.  Union salary and benefit demands may prove burdensome.  And if Nippon Steel’s expectations are not met or the business operating environment undergoes notable shifts, then what?  Nippon Steel interprets its powers quite differently than Washington.  It asserts U.S. Steel is its subsidiary and it has full management flexibility while rejecting the notion Washington calls the shots.  In contrast, Washington claims U.S. Steel is “‘U.S. controlled,’” which is not surprising given the extraordinary powers conveyed to the U.S. government per the national security agreement.[7]  Potential economic gains aside and that a buyout, at least in theory, is easier than starting from scratch, it is hard to fathom why Nippon Steel yielded so much.  Some speculate that Nippon Steel may have decided that that the national security agreement was symbolic rather than substantive.[8]  It is conceivable that the Japanese firm may have felt that it could ingratiate itself with President Trump using flattery, fixers, and gifts to such a degree that it could evade, in practice, the strictures of the national security agreement.  Another possibility is Nippon Steel concluded it could outlast the current administration until a more pliable one took office.

These are big gambles that do not leave much room for error.  If all goes well, then future observers will likely conclude the concessions were a worthy sacrifice and ultimately Nippon Steel gained from making them.  If the deal encounters challenges, however, then future observers will wonder how Nippon Steel’s leadership could have sacrificed so many operating flexibilities that might have enabled the company to adjust and prosper under changing business conditions.  Looking back, that Blast(ed) Furnace that Washington prevented U.S. Steel from shutting down might have been the first sign that Nippon Steel should have steeled itself more vigorously against U.S. deal demands to avoid having to iron them out later.
