Steel Dynamics, Inc. (SDI), together with its subsidiaries (the company), is one of the largest and most diversified domestic steel producers and metals recycler, combined with a meaningful steel fabrication manufacturing platform.

Significant Accounting Policies
Principles of Consolidation
The consolidated financial statements include the accounts of SDI, together with its wholly- and majority-owned or controlled subsidiaries, after elimination of intercompany accounts and transactions. Noncontrolling and redeemable noncontrolling interests represent the noncontrolling owners’ proportionate share in the equity, income, or losses of the company’s majority-owned or controlled consolidated subsidiaries. Redeemable noncontrolling interests related to USS (owned 87.5% by SDI at March 31, 2023 and December 31, 2022) are $75.0 million at March 31, 2023 and $70.3 million at December 31, 2022. Redeemable noncontrolling interests related to Mesabi Nugget (owned 85% by SDI) are $111.2 million at March 31, 2023, and December 31, 2022.
At March 31, 2023, SDI owned 87.5% of the equity interest in USS. Originally, after the fourth anniversary of the initial transaction (March 1, 2023), SDI has an option to purchase, and the noncontrolling members had the option to require the company to purchase, the remaining 12.5% equity interest of USS. On April 1, 2023, a noncontrolling member of USS exercised its option to require SDI to purchase its 2.5% equity interest, increasing SDI’s ownership to 90%. The remaining noncontrolling members’ option to require SDI to purchase the remaining 10% equity interest of USS has been extended to on or after February 28, 2025.
