Cleveland-Cliffs Inc. is partnering with Nucor Corp. to weigh a potential joint bid for United States Steel Corp., according to a person familiar with the matter.

Joint bid for U.S. Steel assets would have Cleveland-Cliffs acquiring blast furnace mills and Nucor taking over Big River Steel, according to CNBC and Bloomberg.

Cleveland-Cliffs is discussing joining with Nucor on a possible bid for U.S. Steel that is still likely months away from happening, according to people familiar with the matter. U.S. Steel had planned to sell itself to Japanese steelmaker Nippon Steel but President Biden earlier this month blocked the transaction over concerns about foreign ownership and national security.
