Biden to kill Nippon Steel’s $15B takeover of US Steel on national security grounds: report

President Biden plans to formally block NipponSteel’s proposed takeover of USSteelon national security grounds once the $15 billion deal is referred back to him later this month, Bloomberg News reported Tuesday, citing people familiar with the matter.

The US national security panel reviewing the deal must refer its decision on the merger to Biden by Dec. 22 or 23, Bloomberg reported. Any referral to the president suggests at least one panel member sees the deal as risky, it added.

Asked for comment on the report, the White House said on Tuesday there was no update on the deal between the two companies. The Committee on Foreign Investment in the United States panel declined to comment.

The Committee on Foreign Investment in the United States (CFIUS) panel reviewing the deal must refer its decision on the merger to Biden by Dec. 22 or 23, Bloomberg added.

The two companies are poised to pursue litigation over the process if Biden decides to block the merger, Bloomberg reported.

Shares of USSteeldropped as much as 21.8% to a two-month low of $30.55 following the Bloomberg report, and triggered multiple trading halts for share price volatility and closed down 10% at $35.26.

The acquisition has faced opposition within the US since it was announced last year with both Biden and hisincoming successorDonald Trump both publicly indicating their intention to block it.

CFIUS told the two companies in September that the deal would createnational security risksbecause it could hurt the supply ofsteelneeded for critical transportation, construction and agriculture projects.

Despite opposition, including from the UnitedSteelworkers Union,Japan’sNippon has pressed on in pursuit of a deal, promising to not transfer any USSteelproduction capacity or jobs outside the US if the merger succeeds.

Nippon has also said it would not interfere in any of USSteel’s decisions on trade matters, including decisions to pursue trade measures under US law against unfair trade practices.

In a bid to win over support from workers, NipponSteelsaid on Tuesday it planned to give employees $5,000 each if the deal with USSteelclosed. It also pledged 3,000 euro closing bonuses to European employees in Europe, which would result in a nearly $100 million total payment to employees.
