| 1. | DESCRIPTION OF BUSINESS
Companhia Siderúrgica Nacional “CSN”, also referred to as “Company”, is a publicly held company incorporated on April 9, 1941, under the laws of the Federative Republic of Brazil (Companhia Siderúrgica Nacional, its subsidiaries, joint ventures, joint operations and associates are collectively referred to herein as the "Group”). The Company’s registered office is located in São Paulo, SP, Brazil. CSN is listed on the São Paulo Stock Exchange (B3 S.A.- Brasil, Bolsa, Balcão) and on the New York Stock Exchange (NYSE). The Group's main operating activities are divided into five (5) segments as follows:
| · | Steel:
The Company’s main industrial facility is the Presidente Vargas Steelworks (“UPV”), located in the city of Volta Redonda, State of Rio de Janeiro. This segment consolidates all operations related to the production, distribution and sale of flat steel, long steel, metallic containers and galvanized steel. In addition to the facilities in Brazil, CSN has commercial operations in the United States and operations in Portugal and Germany in order to gain markets and provide excellent services to final consumers. Its steel is used in home appliances, civil construction, package and automobile industries.
| · | Mining:
The production of iron ore is developed in the cities of Congonhas, Belo Vale and Ouro Preto, State of Minas Gerais, by its subsidiary CSN Mineração S.A. (“CSN Mineração”). The Company’s mining activities also include tin exploration in the state of Rondônia by CSN's subsidiary Estanho de Rondônia S.A. (“ERSA”), to supply the needs of the UPV. The surplus of this raw material is sold to subsidiaries and third parties. Iron ore is sold basically in the international market, especially in Europe and Asia. The prices charged in these markets are historically cyclical and subject to significant fluctuations over short periods of time, driven by several factors related to global demand, strategies adopted by the major steel producers, and the foreign exchange rate. All these factors are beyond the Company’s control. The ore is transported by rail to the Terminal de Carvão e Minérios from the Itaguaí Port (“TECAR”), a solid bulk terminal, one of the four terminals that comprise the Itaguai Port, located in the State of Rio de Janeiro and from TECAR to customers around the world. The imports of coal and coke are also carried out through this terminal by provision of services by CSN Mineração to CSN. As a pioneer in the use of technologies that result in the possibility of stacking the tailings generated in the iron ore production process, CSN Mineração has had its iron ore production, since January 2020, 100% independent of tailings dams. After significant investments in recent years to increase the level of reliability, decharacterization and dry stacking, CSN Mineração has moved towards a scenario in which 100% of its waste goes through a dry filtration process and is arranged in geotechnically controlled piles, in areas exclusively intended for stacking. As a consequence of these measures, the decommissioning of dams is the natural path for processing filtered waste. All our mining dams are adequately suited to existing environmental legislation.
| · | Cement:
CSN entered the cement production market boosted by the synergy between this activity and CSN’s current business. The cement production unit located beside the UPV facilities, in Volta Redonda/RJ, produces CP-III type cement using the slag produced by the UPV’s own blast furnaces. There is also the exploration of limestone and dolomite at the Arcos/MG unit to meet the needs of the steel and the cement plants, as well as the production of clinker at the same unit. On January 31, 2021, the Company concluded the drop down of the cement business and, accordingly, all assets, liabilities, rights and obligations related to the cement business were transferred from CSN to its subsidiary CSN Cimentos S.A. (“CSN Cimentos”). On August 31, 2021, the subsidiary CSN Cimentos S.A. (“CSN Cimentos”) completed the acquisition of control of Elizabeth Cimentos S.A. ("Elizabeth Cimentos") and Elizabeth Mineração Ltda. ("Elizabeth Mineração"), with operations in the Northeast region, especially in Paraíba and Pernambuco. On May 1, 2022, Elizabeth Mineração was merged into CSN Cimentos S.A. On September 9, 2021, CSN Cimentos entered into the Agrément for the Sale and Purchase of the Shares in LafargeHolcim (Brasil) S.A., for the acquisition of 100% of the shares issued by LafargeHolcim (Brasil) S.A. (“LafargeHolcim”). On September 6, 2022, the acquisition of all shares issue by LafargeHolcim S.A. was completed, with the change of LafargeHolcim's name to "CSN Cimentos Brasil S.A.", which is now controlled by CSN Cimentos. The Company's main activities are: production, industry and general trade of cement, lime, mortar, minerals and metals in general and complementary products for civil construction, in natura with industrial plants, warehouses and branches across a large part of the national territory. On August 31, 2023, the Extraordinary General Meeting approved the incorporation of CSN Cimentos by CSN Cimentos Brasil with the consequent transfer of all patrimony, assets (movable and immovable), rights and obligations, in accordance with the terms of the “Protocol and Justification of the Incorporation of CSN Cimentos S.A. by CSN Cimentos Brasil S.A.”. Thus, CSN Cimentos was extinguished, all its shares were canceled and, in replacement, its shareholders received shares in CSN Cimentos Brasil. All activities carried out by CSN Cimentos are now carried out by CSN Cimentos Brasil. The Valuation Report of CSN Cimentos' equity was prepared on June 30, 2023, being the basis for defining a capital increase in CSN Cimentos Brasil in the amount of R$2,383,276.
