| **2.b)** | **Basis of presentation** |

---

The individual and consolidated interim financial information were prepared on a historical cost basis and adjusted to reflect: (i) the fair value measurement of certain financial assets and liabilities (including derivative instruments), as well as pension plan assets; and (ii) impairment losses. Whenever IFRS and CPCs allow for a choice to be made between the acquisition cost or another measurement criterion, the acquisition cost criterion was used.

The preparation of this financial information requires Management to use certain accounting estimates, judgments and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenues and expenses as of the balance sheet date may differ from actual future results. The assumptions used are based on historical data and other factors considered relevant and are reviewed by the Company's Management.

Interim financial information has been prepared and is presented in accordance with CPC 21 (R1) - "Interim Financial Statement" and IAS 34 - "Interim Financial Reporting" in accordance with the standards established by the CVM. This interim financial information does not include all requirements for annual or complete financial statements and therefore must be read together with the Company's annual financial statements for the year ended December 31, 2025.

In this context, this interim financial information was not repeated either due to redundancy or relevance in relation to information previously presented in the following explanatory notes to the annual financial statements:

The accounting records included in the financial information for each of the Company's subsidiaries are measured using the currency of the main economic environment in which each subsidiary operates ("functional currency"). The Parent Company and Consolidated financial statements are presented in R$(Brazilian reals), which is the Company's functional currency and the Group's presentation currency.

Transactions in foreign currencies are translated into the functional currency using the exchange rates prevailing on the respective transaction or valuation dates, through which items are remeasured. The balances of the asset and liability accounts are converted at the exchange rate on the balance sheet date. On March 31, 2026, US$1 is equivalent to R$5.2194 (R$5.5024 on December 31, 2025) and €1 is equivalent to R$6.0117 (R$6.4692 on December 31, 2025), according to rates extracted from the website of the Central Bank of Brazil.

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **BUSINESS COMBINATION** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a)**  **<u>Grupo Estrela</u>** 

In 2025, CSN acquired 70% of the share capital of Estrela Comércio e Participações S.A. ("Estrela Group", "Estrela" or "Tora Group"), in line with its strategy of expansion and integration of logistics operations, focusing on the transport and handling of large volumes of cargo, especially in the mining, steel and cement segments. The transaction strengthens the Company's position as a logistics operator, enabling it to realize operational synergies and make more efficient use of infrastructure in the regions where the Group operates.

The Estrela Group already had a business relationship with the Company, which contributes to a more efficient integration of operations and maximizes economies of scale.

**<u>Acquisition of 70% Estrela Comércio e Participações S.A.'s share capital. (Grupo Estrela)</u>**

On April 1, 2025, the Company completed the acquisition of 70% of the share capital of Estrela Comércio e Participações S.A., holding company of the road and multimodal logistics group known as TORA Group. The initial value of the transaction was R$742,500, of which R$300,000 was paid on the closing date and the remaining balance to be settled in three annual installments: R$111,250 on April 1, 2026, R$111,250 on April 1, 2027 and R$220,000 on April 1, 2028.

In September 2025, an additional payment of R$9,994 was made, referring to the purchase price adjustment. Thus, the total nominal amount of the operation became R$752,494.

Estrela is the parent company of several operating companies that provide road and intermodal logistics services, warehousing, equipment leasing, and related services, including Tora Transportes Ltda., Tora Locações S.A., FJX Transportes S.A., N. Minas Transportes e Locações Ltda., Saratoga Transportes Ltda., Lokamig Rent a Car S.A., Seminovos Lokamig Ltda., Tora Logística Armazéns e Terminais Multimodais S.A., Tora Recintos Alfandegários S.A., and Tora Seminovos Comércio de Veículos Ltda., which have become part of the Company's group of indirect subsidiaries.

For accounting purposes, the Company was identified as the acquirer, having obtained control of Estrela on the acquisition date, based on its 70% ownership of the voting capital and its ability to direct Estrela's financial and operational policies. Consequently, Estrela and its subsidiaries have been fully consolidated in the Company's financial statements effective April 1, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;**(iii) <u>Goodwill on acquisition of control</u>**

In accordance with item 32 of CPC15 (R1)/IFRS3, the acquiror must recognize goodwill for expected future profitability as of the acquisition date, which is measured according to the amount by which the purchase price exceeds the fair value of assets and liabilities acquired (allocation of the purchase price). The transaction generated goodwill based on expected future profitability, as shown in the table below:

within the CSN Group;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gains in scale and efficiency;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Capacity to expand within the logistics
market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Additionally, expected future profitability.

Goodwill arising from the transaction is expected to result in a tax benefit, i.e., to be deductible for tax purposes.

Goodwill is part of the investment's carrying amount. In the Consolidated Financial Statements, goodwill is recognized as an intangible asset and, because it has an indefinite useful life, is not amortized, in accordance with CPC 04 (R1)/IAS 38; it is tested for impairment at least annually.

Due to the acquisition of Global Dot on December 5, 2025, the Company began the contracting process for the allocation of the purchase price (PPA) in 2026 in order to identify and measure the assets acquired and liabilities assumed at fair value. For preliminary disclosure purposes, the amount initially recognized as fair value for acquired assets is considered the book value of the acquiree's equity on the transaction base date. This amount totals R$11,728 and is subject to adjustments arising from the completion of the fair value measurement process, which may impact the final value of the goodwill recognized.

(\*) Considering that the acquisition was completed on December 5, 2025 and there were no material transactions made in the last month of the year, there was no impact on the Company's financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) impact on the Company's consolidated
financial statements ("FSs") in fiscal year 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) impact on FSs if the acquisition date
had occurred at the start of the 2025 fiscal year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c)**  **<u>Measurement and Appraisal Reports related to Business Combinations</u>** 

As of the date of these financial statements, the process of measuring and preparing fair value appraisal reports for the identifiable assets acquired and liabilities assumed—including separable intangible assets—is currently underway with independent appraisers, in accordance with the measurement period of up to 12 months. Therefore, the amounts recognized are provisional and may be subject to minor adjustments upon completion of the purchase price allocation (PPA) reports, except in the case of the Estrela Group, for which the valuation report has been finalized. For this case, the Company concluded that it obtained the necessary information about the facts and circumstances existing on the acquisition date, and there is no additional relevant information to be obtained.

(1) The Brazilian federal tax balance mainly refers to PIS and COFINS, IRPJ and CSLL and IPI.

Accumulated tax credits generally derive from ICMS, PIS and COFINS credits on purchases of inputs and property, plant, and equipment used in production. The realization of these credits generally occurs through offsetting with debits of these taxes, generated by sales operations and other taxed outputs.

Due to the mining industry's predominantly export-oriented nature, there was an increase in the balance of ICMS, PIS, and COFINS credits during the period, primarily attributable to CAPEX investments made as part of the Congonhas Mining Expansion Project, as well as the purchase of ore from third parties.

The balance of recoverable taxes maintained in the short term is expected to be offset in the next 12 months.

**(In thousands of Reals, unless stated otherwise)**

Based on budget analyses and projections approved by Management, there is no forecast of risks regarding the non-realization of these tax credits, provided that such budget projections materialize.

(1) In December 2025, CSN sold 59.5% of its equity interest in MRS to its subsidiary CSN Mineração and now holds a 7.59% stake in MRS. As of the same date, its subsidiary CMIN came to hold a 29.91% participation in MRS. This transaction was carried out for the total price of R$3,350,000 previously received by CSN, and the book value of MRS's investment was written off in the amount of (R$998,922). Consequently, a gain of R$2,351,078 was recorded under "Other operating income" (Note 27), and as required by CPC 18 and ICPC 09, "Transactions under common control," it was offset at the Parent Company through the unrealized gain in CSN Mineração. This sale did not represent a realized gain or loss for the CSN Group. Effective economic realization of the investment will only take place once the sale is made outside CSN's economic group.

(1) They refer to iron ore prepayment bonds that were initially recognized as contract liabilities, as they refer to a future obligation to deliver the product. However, given the impossibility of delivering the product during the period and the need for a cash settlement, this obligation came to be characterized as a monetary item and was reclassified as financial liability. These amounts were fully settled for the period.

(2) Amounts include unrealized changes in exchange rate and inflation, as well as costs of capital raising.

· **Covenants**

 

The Company's debt contracts provide for compliance with certain non-financial obligations, as well as maintenance of specific performance parameters and indicators, such as the disclosure of audited financial statements according to regulatory deadlines or having early maturity declared if the net debt to EBITDA indicator reaches the levels specified in these contracts.

As of the present date, the Company is compliant with the financial and non-financial obligations (covenants) of its current contracts.

| **14.a)** | **Identification and Valuation of Financial Instruments** |

---

The Company may operate with several financial instruments, with an emphasis on cash and cash equivalents, including investments, marketable securities, accounts receivables from customers, accounts payables to suppliers and borrowings and financing. Additionally, the Company may also operate with financial derivatives, such as swap of exchange or interest and commodities and exchange derivatives.

Given the nature of these instruments, fair value is essentially determined through the use of observable quotations in active markets, particularly B3 S.A. – Brasil, Bolsa, Balcão. The amounts recorded in current assets and liabilities have immediate liquidity or maturity, mostly in the short term. Considering the terms and characteristics of these instruments, the carrying amounts approximate the fair values.

| **14.b)** | **Financial Risk Management** |

---

The Company uses risk management strategies, with guidance on the risks incurred on the business.

The nature and general position of financial risks are regularly monitored and managed to assess results and the financial impact on cash flow. Credit limits and the hedge quality of counterparties are also periodically reviewed.

Market risks are hedged when considered necessary to support the corporate strategy or when it is necessary to maintain the level of financial flexibility.

The Company is exposed to exchange rate, interest rate risk, market price, and credit and liquidity risk.

The Company may manage some of the risks using derivative instruments not associated with any speculative trading or short selling.

![](image_110.jpg)

**(In thousands of Reals, unless stated otherwise)**

&nbsp;&nbsp;&nbsp;&nbsp;**i)** **Exchange Rate Risk** 

The exposure arises mainly from the existence of assets and liabilities denominated in dollars, since the Company's functional currency is substantially the Real and is called natural foreign exchange exposure. The net exposure is the result of the offsetting the natural exchange exposure by the instruments of hedge adopted by the Company.

The consolidated net exposure is shown below:

(\*) Total notional value of derivative and non-derivative financial instruments used for exchange risk management.

The Company uses Hedge Accounting as a strategy, as well as derivative financial instruments to protect future cash flows.

**Sensitivity analysis of Derivative Financial Instruments and Consolidated Foreign Exchange Exposure**

The Company evaluated two different scenarios for the analysis of the exchange rate impact: Scenario 1 projects a horizon of increased currency volatility, and Scenario 2 predicts a horizon of currency appreciation. The calculation was based on the closing exchange rate on March 31, 2026, using assumptions based on a dispersion calculation that considers both historical variations in exchange rates and projections developed by management.

The currencies used in the sensitivity analysis and their respective scenarios are shown below:

**ii)** **Interest Rate Risk**

This risk arises from short-term and long-term investments, loans and financing and debentures linked to pre-fixed and post-fixed CDI, TJLP, and SOFR interest rates, which expose these financial assets and liabilities to interest rate fluctuations as shown in the sensitivity analysis table.

**Sensitivity Analysis of Interest Rate Changes**

Below, we present the sensitivity analysis for risks related to interest rates. The Company considered two different scenarios to assess the impact of variations in these rates: Scenario 1 predicts a horizon of rising interest rates, and Scenario 2 projects a reduction horizon. To carry out the calculation, the closing rates on March 31, 2026 were considered as references, based on a dispersion model, which considers not only the historical variations in interest rates, but also detailed projections by the management.

This approach allows for a comprehensive and precise assessment of potential economic impacts arising from interest rate fluctuations.

**iii)** **Market price risk**

The Company is also exposed to market risks related to the volatility of commodity and input prices. In line with its risk management policy, risk mitigation strategies involving commodities may be used to reduce cash flow volatility. These mitigation strategies may incorporate derivative instruments, predominantly forward, futures, and options transactions.

![](image_110.jpg)

**(In thousands of Reals, unless stated otherwise)**

Below are the price risk protection instruments, as shown in the following topics:

 **

***a)* Cash flow Hedge Accounting – "Platts" Index**

 **

To better reflect the accounting effects of the "Platts" hedge strategy on the result, the subsidiary CSN Mineração opted to formally designate the hedge and, consequently, adopted hedge accounting for the iron ore derivative as a hedge accounting instrument for its highly probable future iron ore sales. As a result, the mark-to-market arising from the "Platts" volatility will be temporarily recorded in equity and will be taken to the income statement when the sales occur according to the contracted evaluation period. This allows the recognition of "Platts" volatility on iron ore sales to be recognized at the same time.

The Company has periodically reviewed market scenarios to assess its exposure to iron ore price risk to ensure adequate coverage of market price fluctuations. This process involves monitoring fluctuations and trends in global prices, in addition to considering economic and geopolitical factors that may impact the value of this commodity.

The table below shows the result of the derivative instrument up to March 31, 2026:

The cash flow hedge - "Platts" index was fully effective since the contracting of derivative instruments.

To support the designations, the Company prepared formal documentation indicating how the cash flow hedge accounting designation - "Platts" index aligns with CSN's risk management objectives and strategy, identifying the protection instruments used, the hedge object, the nature of the risk to be protected, and demonstrating the expectation of high effectiveness of the designated relationships. Iron ore derivative instruments ("Platts" index) were designated in amounts equivalent to the portion of future sales, comparing the designated amounts with the expected and approved amounts in the budgets of the Management and Board.

**b) Cash flow Hedge Accounting** 

**Foreign Exchange Hedge**

The Company and its subsidiary CSN Mineração formally designate cash flow hedge relationships to protect highly probable future flows exposed to the dollar related to sales made in dollars.

With the objective of better reflecting the accounting effects of the foreign exchange hedge strategy in the results, CSN and its subsidiary CSN Mineração designated part of their dollar liabilities as a hedge instrument for their future exports. As a result, the exchange rate variation from designated liabilities will be temporarily recorded in shareholders' equity and will be transferred to the income statement when the respective exports occur, thus allowing the recognition of dollar fluctuations on the liability and exports to be recorded at the same time. It is emphasized that the adoption of this hedge accounting does not imply the contracting of any financial instrument.

The table below presents the summary of hedging relationships as of March 31, 2026:

**iv)** **Credit risks**

The exposure to credit risks of financial institutions observes the parameters established in the financial policy. The Company's practice is the detailed analysis of the equity and financial situation of its customers and suppliers, the establishment of a credit limit and the permanent monitoring of its outstanding balance.

Regarding financial investments, the Company only makes investments in institutions with low credit risk assessed by credit rating agencies. Since part of the resources is invested in repurchase agreements that are backed by Brazilian government securities, there is also exposure to the credit risk of the Brazilian State.

![](image_110.jpg)

**(In thousands of Reals, unless stated otherwise)**

Regarding credit risk exposure in trade and other receivables, the Company has a credit risk committee where each new customer is individually analyzed for their financial condition before credit limits and payment terms are granted. This is periodically reviewed according to the procedures specific to each business area.

&nbsp;&nbsp;&nbsp;&nbsp;**v)** **Liquidity Risk** 

It is the risk that the Company may not have sufficient net funds to honor its financial commitments as a result of the mismatch of term or volume between expected receipts and payments.

Future receipt and payment premises are established to manage cash liquidity in domestic and foreign currencies, which are monitored on a day-to-day basis by the Treasury department. Payment schedules for long-term installments of loans, financing and debentures are presented in note 13.

**Fair Values of Assets and Liabilities in Relation to Book Value**

Assets and liabilities measured at fair value through profit or loss are recognized under financial results. However, when designated for hedge accounting operations, fair value adjustments are recorded under other comprehensive income up until the moment they are realized, when they are then recorded under other operating income (expenses), according to the nature of the operation.

The amounts are recorded in the financial statements at their book value, which are substantially similar to those that would be obtained if they were traded in the market. The fair values of other long-term assets and liabilities do not differ significantly from their carrying amounts, except for the amounts below.

The estimated fair value for certain consolidated long-term loans and financing were calculated at current market rates, considering the nature, term and risks similar to those of the registered contracts, as follows:

**Sensitivity Analysis for Stock Price Risks**

We present below the sensitivity analysis for the risks related to the stock price variation. The Company evaluated two distinct scenarios for the impact of price fluctuations: Scenario 1 (extreme optimistic) forecasts a horizon of price appreciation, and Scenario 2 (extreme pessimistic) considers a horizon of deterioration in price volatility. The calculation was based on the closing price of the shares on March 31, 2026, using assumptions based on both the dispersion of historical variations in prices and projections prepared by Management.

**Lease payments not recognized as liabilities:**

The Company chose not to recognize lease liabilities in contracts with a term of less than 12 months and for low value assets. Payments made for these contracts are recognized as expenses when incurred.

The Company has lease contracts for port terminals (TECAR and TECON) and a concession contract for the operation and development of public rail freight transport services in the Northeast Network I (FTL). Although these contracts establish minimum performance requirements, it is not possible to determine their cash flow since the payments are entirely variable and will only be known when they occur. In such cases, payments will be recognized as expenses when incurred.

Expenses related to payments not included in the measurement of the lease liability are:

During the period between 2021 and 2025, these subsidiaries generated profits in the amount of R$8,276. If the Brazilian tax authorities understand that these profits are subject to additional taxation in Brazil through income tax and social security contributions, these amounts, if due, would total approximately R$2,814.

Provisions for taxes, social security, labor, civil and environmental matters have been estimated by management and substantially substantiated by legal counsel, and only those causes that are considered probable of loss are recorded. These provisions also include tax liabilities arising from actions taken at the Company's initiative, plus SELIC (Special System for Settlement and Custody) interest.

![](image_110.jpg)

**(In thousands of Reals, unless stated otherwise)**

**<u>Tax Proceedings</u>**

The main legal proceedings considered by external legal consultants as having a probable loss probability, in which CSN or its subsidiaries are parties, of a tax nature are: (i) some ISS tax infraction notices; (ii) divergences between calculated and collected ICMS; and (iii) Compensation requests not approved due to lack of credit rights.

**<u>Labor lawsuits</u>**

The Group appears as a defendant in labor claims. Most of the claims in these lawsuits relate to subsidiary and/or joint liability, equal pay, hazard and danger pay allowances, overtime, health plans, compensation claims for alleged occupational diseases or work accidents, intra-day break periods, and differences in profit sharing for the years 1997 to 1999 and 2000 to 2003.

Throughout the period ended March 31, 2026, there were changes in additions and write-offs of labor proceedings resulting from definitive closure, in addition to the constant review of the Company's accounting estimates in relation to provisions and contingencies, which consider the different nature of the claims involved, as established in the Company's accounting policies.

**<u>Civil Lawsuits</u>**

Among the civil lawsuits in which he appears as a defendant, there are mainly lawsuits with a claim for compensation. Such processes, in general, are resulting from work accidents, occupational diseases, contractual discussions related to the Group's industrial activities, real estate actions, health plans.

**<u>Environmental Processes</u>**

The main environmental proceedings considered by external legal consultants as having probable loss probability, in which CSN or its subsidiaries are parties, are (i) administrative violation notices for alleged environmental infractions; (ii) annulment lawsuits and tax foreclosures resulting from environmental fines; and (iii) procedural fines for alleged non-compliance with court orders.

Among the environmental administrative/judicial proceedings in which the Company is a defendant are administrative procedures aimed at verifying possible environmental irregularities and regularizing environmental licenses. In the judicial sphere, there are actions to enforce fines imposed due to such alleged irregularities and public civil actions seeking regularization combined with compensation, which consist of environmental restoration in most cases. Such processes are generally derived from discussions of supposed environmental impacts related to the Company's industrial activities.

<u>Administrative and Judicial Proceedings</u>

The Company does not make provisions for legal proceedings whose expectation of the Management, based on the opinion of legal advisors, is of possible loss. The following table shows a summary of the balance of the main matters classified as possible risk compared to the balance of March 31, 2025 with December 31, 2025.

The Company has other cases classified by its legal counsel as having a possibility of loss; therefore, they represent present obligations for which an outflow of resources is not probable. As of March 31, 2026, these amounted to R$48,466,842 (R$47,419,219 as of December 31, 2025), of which R$3,134,584 relates to labor lawsuits (R$2,894,042 as of December 31, 2025), R$4,118,755 to civil lawsuits (R$3,845,589 as of December 31, 2025), R$39,127,340 in tax proceedings (R$38,597,353 as of December 31, 2025), and R$1,886,163 in environmental proceedings (R$2,082,235 as of December 31, 2025).

In the 1st quarter of 2021, the Company was notified of the start of an arbitration proceeding based on an alleged breach of iron ore supply contracts. The opposing party's claim at that time totaled approximately US$1 billion, and the Company understands the allegations presented to be unfounded by the complete absence of damages, based on the assessment of its legal advisors. The Company wishes to inform that it has prepared, together with its legal advisors, a response to the arbitration request and is currently preparing its defense. It also wishes to clarify that discussions involve ongoing arbitration disputes initiated by both parties. It is also estimated that arbitration will be completed in approximately 9 months. The relevance of the proceedings for the Company is related to the value attributed to the cause and the possible financial impact.

The Company has provided judicial guarantees (Surety Bonds) in the total amount, adjusted as of March 31, 2026, of R$10,911 (R$11,020 as of December 31, 2025), in accordance with current procedural law.

Evaluations carried out by legal advisors have defined these administrative and judicial proceedings as a possible risk of loss, and a provision has not been established in accordance with Management's judgment and accounting practices adopted in Brazil.

&nbsp;&nbsp;&nbsp;&nbsp;**21.** **PROVISIONS FOR ENVIRONMENTAL LIABILITIES AND ASSET RETIREMENT OBLIGATIONS**

As of March 31, 2026, a provision remains in place to cover expenses related to services for the investigation and environmental remediation of potentially contaminated, degraded, and currently exploited areas for which the Company is responsible in Brazil. Expense estimates are reviewed periodically, adjusting, whenever necessary, the amounts already accounted for. These are Management's best estimates considering environmental recovery studies and projects. These provisions are recorded in the other operating expenses account.

Some contingent environmental liabilities are monitored by the environmental area and have not been provisioned because their characteristics do not meet the recognition criteria in IAS 37/CPC 25.

&nbsp;&nbsp;&nbsp;&nbsp;**29.** **SEGMENT INFORMATION** 

According to the Group's structure, the businesses are distributed and managed in five operating segments as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Steel operations** 

The Steel segment consolidates all operations related to the production, distribution and marketing of flat steel, long steel, metal packaging and galvanized steel, with operations in Brazil, United States, Portugal and Germany. The segment serves the construction, steel packaging for the chemical and food industries, home appliances, automotive, and OEM (engines and compressors) markets.

The Company's steel units produce hot-rolled, cold-rolled, galvanized, and pre-painted steel with great durability. It also produces tinplate, a raw material used in the production of packaging.

![](image_110.jpg)

**(In thousands of Reals, unless stated otherwise)**

Operations in Brazil also involve the production and marketing of long steels, which consolidates the Company's position as a source of complete solutions for civil construction, complementing its portfolio of high value-added products in the steel chain.

Abroad, Lusosider, in Portugal, produces cold rolled and galvanized steels. CSN LLC, in the United States, serves the local market through the import and marketing of steel products. Stahlwerk Thüringen (SWT), located in Germany, produces long steel and is specialized in the production of steel profiles used in civil construction.

In March 2025, the Company acquired the company Gramperfil S.A. which is located in Portugal. This acquisition will complement local operations involving the production, importing, marketing and processing of metal profiles and accessories used in metallic and civil construction.

In November 2025, the Company acquired Galvacolor Jerez, S.L.U., which is located in Spain. Its activities consist of processing and sale of steel and steel products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Mining** 

Covers the mining and marketing activities of iron ore and tin.

Iron ore high quality operations are located in the Iron Quadrangle, in Minas Gerais, which, besides producing, also market iron ore purchased from third parties.

At the end of 2015, CSN and the Asian Consortium formalized a shareholders' agreement to combine assets related to iron ore operations and related logistics, forming a new company that concentrated the Group's main mining activities starting in December 2015. Based in this context, the new company, currently called CSN Mineração S.A., came to hold the lease of TECAR, as well as the Casa de Pedra mine and all Namisa shares, which was incorporated on December 31, 2015. CSN still holds 100% of Minérios Nacional which includes the mines of Fernandinho (operational), Cayman and Pedras Pretas (mineral resources), all located in Minas Gerais.

In addition, CSN controls Estanho de Rondônia S.A., a company with tin mining and smelting units in the state of Rondônia.

On October 7, 2022, CSN Mineração and CSN Energia completed the acquisition of the Quebra-Queixo Hydroelectric Plant, with an installed capacity of 120 MW, located in the city of Ipuaçu/SC, making CSN Mineração self-sufficient in electricity and strengthening its industrial competitiveness through greater cost predictability and energy generation from a 100% renewable source.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Logistics** 

**i. Railway**

CSN has a stake in three railway companies: MRS Logística S.A., which manages Rede Ferroviária Federal S.A.'s former Southeast Network, Transnordestina Logística S.A. and FTL - Ferrovia Transnordestina Logística S.A. FTL - Ferrovia Transnordestina Logística S.A., which hold the concession for the former RFFSA Northeast Network in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas.

**a) MRS** 

The rail transport services provided by MRS are fundamental to the supply of raw materials and the transport of final products. The entirety of the iron ore, coal and coke consumed at the Presidente Vargas Plant is transported by MRS, as well as part of the steel produced by CSN both for the domestic market and for export.

The southeastern Brazilian railway system, which spans 1,674 km of railway network, serves the industrial triangle of São Paulo - Rio de Janeiro - Minas Gerais in the Southeast region, connecting mines in Minas Gerais to ports in São Paulo and Rio de Janeiro, and to steel mills belonging to CSN, Companhia Siderúrgica Paulista (or Cosipa) and Gerdau Açominas. In addition to serving other customers, the line transports iron ore from the Casa de Pedra mine in Minas Gerais, as well as coke and coal from the Port of Itaguaí in Rio de Janeiro, to Volta Redonda, Rio de Janeiro, and products destined for export to the Ports of Itaguaí and Rio de Janeiro.

**b) TLSA and FTL** 

TLSA and FTL hold the concession of the former RFFSA Northeast network. The northeastern railway system covers 4,238 km of railway network divided into two sections: i) Network I, which includes the sections of São Luiz - Mucuripe, Arrojado - Recife, Itabaiana - Cabedelo, Paula Cavalcante - Macau - and Propriá - Jorge Lins; and ii) Network II, which includes the sections of Missão Velha - Salgueiro, Salgueiro - Trindade, Trindade - Eliseu Martins and Missão Velha - Porto de Pecém.

In addition, it connects to the region's major ports, offering a significant competitive advantage through opportunities for intermodal transport solutions and customized logistics projects.

**ii. Port**

The Company's activities in port logistics sector were consolidated through the operation of the Sepetiba terminal, which was built after a port modernization law (Law 8.630/1993) allowing the transfer of port activities to the private sector was passed. The Sepetiba terminal offers the infrastructure required to meet all the needs of exporters, importers and shipowners. Its installed capacity exceeds that of most Brazilian terminals.

The Company's ongoing investment in terminal projects has consolidated the Itaguaí Port Complex as one of the most modern of its kind in Brazil.

**(In thousands of Reals, unless stated otherwise)**

**iii. Land Transport**

On April 1, 2025, CSN completed the acquisition of Estrela Comércio e Participações S.A., Grupo Estrela's ("Grupo Estrela") holding company. Founded in the 1970s to initially meet road transport needs, Grupo Estrela currently comprises an "Integrated Logistics System", which seeks integrate modes of transport, especially in road-rail operations and transport in the steel, mining, solid bulk, automotive and dry cargo sectors in general. The Tora Group's services portfolio also includes terminal management, storage, operation of bonded warehouses, and production chain and light vehicle fleet management services, including the rental and resale of used vehicles.

Grupo Estrela maintains a national and international presence in the transport sector. The Group relies on more than 70 branches distributed throughout Brazil. It currently operates at four multimodal terminals located in the Southeast region of Brazil and a border terminal located in the city of Uruguaiana/RS. In the customs bonded warehouses segment, the company operates a terminal located in the city of Betim, Minas Gerais, which receives imported goods from the country's major ports and airports.

In March 2024, the Estrela Group entered the light vehicle sector (fleet management, leasing, and pre-owned vehicle sales) through the acquisition of the Lokamig Group.

&nbsp;&nbsp;&nbsp;&nbsp;· **Energy** 

CSN is one of the largest industrial consumers of electricity in Brazil. As energy is a fundamental input in its production process, the Company owns electric power generation assets, and with the acquisitions made in 2022, it achieved energy self-sufficiency before coming to operate in the sector as an electric power generation player through the commercialization of its surplus.

With the acquisitions, the CSN group now offers a portfolio of generation assets with a total installed capacity of 2,011 MW, which comprise the following assets:

1. Itá Hydroelectric Power Plant,
located in the state of Santa Catarina, in which CSN holds a 29.50% stake through the Itá Energética S.A SPE, with an installed
capacity equivalent to its 428 MW stake;

de Energia Elétrica – CEEE-G, located in Rio Grande do Sul state, with a platform of 13 own Hydroelectric Plants, wind and
solar assets, plus minority participation in other ventures, reflecting an installed capacity of 1,119 MW.

&nbsp;&nbsp;&nbsp;&nbsp;· **Cement** 

The Cement sector, for which operations are maintained through CSN Cimentos Brasil S.A., consolidates the production, sale and distribution of cement, aggregates and concrete. The slag used in plants located in the Southeast region is produced by the blast furnaces at the Presidente Vargas Plant itself, in Volta Redonda/RJ.

The Company has intensified its strategy of expanding to new regions, starting with the acquisition of Elizabeth Cimentos S.A. and Elizabeth Mineração Ltda. on August 31, 2021, which maintain operations in Brazil's Northeast region and contribute 1.3 Mtpa of cement production capacity.

On September 6, 2022, relevant advances were made in the company's cement-related business in terms of its capacity and geographic positioning through the acquisition of LafargeHolcim (Brasil) S.A. This asset will add a total of 11 million tons of cement production capacity, in addition to introducing new businesses areas to the Company's current portfolio: Aggregates and Concrete. Taking all operations into account, CSN's Cement segment is currently the second largest in Brazil in terms of effective production capacity, totaling 17 million tons per year.

Cement plants are located in the states of Minas Gerais, Rio de Janeiro, Espírito Santo, Bahia, Goiás and São Paulo. The production process occurs basically through grinding the main raw materials which include clinker, limestone, gypsum, and slag.

The company currently serves the cement market with a broad product portfolio suitable for both the technical segment and the distribution market, according to ABNT NBR 16697. The cement is sold in both bagged and bulk form.

In addition to the operations described above, CSN Cimentos Brasil S.A. owns two power generation assets acquired on June 30, 2022: the Santa Ana small hydroelectric plant, located in the municipality of Angelina/SC, with an installed capacity of 6.50 MW, and the Sacre II small hydroelectric plant, located in the municipality of Brasnorte/MT, with an installed capacity of 30 MW.

&nbsp;&nbsp;&nbsp;&nbsp;· **Sales by Geographic Area** 

Sales by geographic area are determined based on customers' location. National sales on a consolidated basis are represented by revenues from customers located in Brazil and export sales represent revenues from customers located abroad.
