U.S. Steel said on Wednesday an arbitration board had ruled in favor of Nippon Steel’s $14.9 billion buyout of the company, but that the United Steelworkers union disagreed with the decision.
The board, jointly selected by the company and the union to settle disputes, ruled that U.S. Steel had satisfied each of the conditions of the successorship clause in its basic labor agreement with the USW.
“The arbitrators accepted at face-value Nippon Steel’s statement that it would assume the Basic Labor Agreement,” USW said.
The union said the decision did not change its opposition to the deal.
“We remain focused on forging a productive relationship with the USW, which includes fulfilling our commitments that go far beyond what is currently required in the existing BLA,” Nippon Steel said in a statement.
The deal has faced political opposition since it was signed last December. Democratic presidential candidate Kamala Harris and her Republican challenger Donald Trump have supported U.S. Steel remaining American-owned.
Nippon Steel had paid a hefty premium to clinch the deal for U.S. Steel on a bet that it could benefit from U.S. President Joe Biden’s infrastructure spending bill.
Earlier this month, U.S. Steel warned that a failure to conclude the deal would put thousands of U.S. union jobs at risk and signaled that it would close some steel mills and potentially move its headquarters out of the politically important state of Pennsylvania.
Nippon Steel plans to close the deal by the end of December, pending regulatory approvals, and this month resubmitted an application for approval to the U.S. national security panel, delaying a decision on the politically-sensitive merger until after the Nov. 5 presidential election.
