Business Combinations and Investments in Unconsolidated Affiliates | Note 2. Business Combinations and Investments in Unconsolidated Affiliates Business Combinations ROCA The company acquired 100% of ROCA ACERO, S.A. de C.V. (ROCA) on October 1, 2022. The acquisition of ROCA is part of the company’s North American raw material procurement strategy. ROCA is headquartered in Monterrey, Mexico, and operates five ferrous and nonferrous scrap facilities strategically positioned near high-volume industrial scrap sources located throughout Central and Northern Mexico. The transaction was funded with available cash. Post-acquisition operating results are reflected in the company’s financial statements in the metals recycling operations segment. Aluminum Dynamics The company attained a 94.4% equity interest in a joint venture concurrently formed with Unity Aluminum, Inc. on July 29, 2022, for the construction and operation of a new state-of-the-art low-carbon aluminum flat roll mill. The transaction was funded with available cash. Operating results from and after July 29, 2022, are reflected in the company’s consolidated financial statements, in other operations. ​ United Steel Supply The company purchased a 75% equity interest in United Steel Supply, LLC (USS) on March 1, 2019 and on April 1, 2022, the company purchased an additional 12.5% in the equity interest of USS. The company has an option to purchase, and the sellers have the option to require the company to purchase, after the fourth anniversary of the transaction (March 1, 2023), the remaining 12.5% equity interest of USS. The USS noncontrolling interest is therefore reflected in redeemable noncontrolling interest in the consolidated balance sheets. ​ Zimmer The company acquired 100% of Zimmer, S.A. de C.V. (Zimmer) in August 2020 from available cash. The acquisition of Zimmer is part of the company’s raw material procurement strategy to support its new Sinton Flat Roll Division. Headquartered in Monterrey, Mexico, Zimmer operates several ferrous and nonferrous scrap facilities strategically positioned near high-volume industrial scrap sources, and several third-party scrap processing locations, located throughout Central and Northern Mexico. Zimmer’s post-acquisition operating results are reflected in the company’s financial statements in the metals recycling operations segment. ​ Investments in Unconsolidated Affiliates The company purchased a 45% minority equity interest in New Process Steel, L.P. (NPS) on January 31, 2022. NPS is a metals solutions and distribution supply-chain management company headquartered in Houston, Texas, with a focus toward growing its value-added manufacturing applications. On February 28, 2022, the company also purchased a minority equity interest in Aymium, a producer of renewable biocarbon products. As the company does not have power to control these entities, the company accounts for these investments using the equity method of accounting, which are recorded in Other Assets (noncurrent) in the company’s consolidated balance sheets with related activity recorded in Other (Income) Expense, net. Profits or losses from transactions with NPS are eliminated until realized by the majority equity interest owner.
