CSN’s Consolidated Results

· Net revenue in 2Q19 totaled R$6,901 million, 21% and 15% higher than in 2Q18 and 1Q19, respectively. The strong growth was mainly due to the improvement in mining performance.

· Cost of goods sold totaled R$4,442 million in 2Q19, 8% and 10% higher than in 2Q18 and 1Q19, respectively. Costs in the steel segment increased in comparison to 1Q19 due to the end of blast furnace number 3 campaign and costs of goods sold in the mining segment increased due to higher sales volume.

· Gross profit totaled R$2,458 million in 2Q19, 24% higher than in 1Q19. Gross margin increased 2.6 p.p. versus 1Q19, reaching 35.6% in 2Q19, mainly due to improved performance in mining, as well as logistics, energy and cement segments.

· General and administrative expenses totaled R$126 million in 2Q19, with a dilution from 2.0% (1Q19) to 1.8% (2Q19) of net revenue. Selling expenses totaled R$426 million, or 6.2% of net revenue, 3.4 p.p. lower than the amount recorded in 1Q19 (9.5% of net revenue) due to efficiency in hiring freight in the period’s shipments.

· Net other income (expenses) was an expense of R$802 million in 2Q19, mainly to non-cash items, such as: (i) the devaluation of Usiminas shares and (ii) the recognition of hedge accounting expenses.

· Net financial result was an expense of R$358 million in 2Q19, lower than the 1Q19, mainly due to the variation in exchange rate with positive effect in results. Financial expenses (ex-exchange variation) remained stable when compared to the previous quarter, reaching R$641MM, affected by bond repurchase expenses.

· Adjusted EBITDA reached R$2,380 million in 2Q19, versus R$1,724 million in 1Q19, 38% increase due to better contribution from mining segment, while adjusted EBITDA margin reached 33.5%, or 5.8 p.p. higher during the same period.

Adjusted EBITDA (R$ MM) and Adjusted EBITDA Margin¹ (%)

¹ Adjusted EBITDA margin is calculated as the ratio between adjusted EBITDA and adjusted net revenue, considering the stakes of 100% in CSN Mineração, 37.27% in MRS and 50% in CBSI.

Free Cash Flow1

Operating cash flow, as measured by free cash flow was positive by R$856MM in 2Q19, influenced by stability in working capital and the excellent EBITDA performance in the quarter.

Quarterly Financial Information - June 30, 2019 – CIA SIDERURGICA NACIONAL | Version: 1

¹ The free cash flow is calculated from adjusted Ebitda less Ebitda of joint ventures, Capex, Income tax, financial result and variation of working capital, excluding the effect of Glencore’s advance.

Debt

On 06/30/2019, consolidated net debt reached R$26,641 million, while net debt/EBITDA, calculated based on LTM adjusted EBITDA, reached 3.65x, or 0.42x lower than in 1Q19. Considering the second prepayment with Glencore, the leverage reached 3,52x. The evolution of leverage in the quarter was affected by the distribution of dividends in the amount of R$1,151 million.

Foreign Exchange Exposure

The net FX exposure (excluding the Perpetual Bond) of the consolidated balance sheet on 06/30/2019 was US$958 million, as shown in the table below. It should be noted that the net foreign exchange exposure includes a liability of US$1.0 billion in line item “Loans and Financing” related to the Perpetual Bond, which, due to its nature, will not require disbursement to settle the principal amount in the foreseeable future.

The Hedge Accounting adopted by CSN correlates projected export inflows in dollars with part of the scheduled debt payments in the same currency. Therefore, the exchange variation of the dollar-denominated debt is temporarily accounted for under shareholders’ equity, being recorded in the income statement when dollar revenues from exports are received.

Working Capital

To calculate working capital, CSN adjusts its assets and liabilities as shown below:

· Accounts receivable: excludes dividends receivable, advances to employees and other receivables;

· Inventories: includes estimated losses and excludes spare parts;

· Prepaid taxes: composed only of the portion of income tax and social contribution included in recoverable taxes;

· Taxes payable: includes taxes in installments;

· Advances from customers: sub-account of other liabilities recorded under current liabilities; excludes the advance from Glencore and

· Suppliers: Includes Drawee Risk

Accordingly, working capital invested in the business totaled R$3,425 million in 2Q19, increasing by R$81MM compared to 1Q19, due to temporary increases in inventories and accounts receivable. Specifically, Blast Furnace #3 shutdown increased the slab inventory in anticipation of the period of lower production, while the growth in accounts receivable was mainly due to the concentration of iron ore shipments sold at the end of the period.

· Cost of goods sold increased by 5% in 2T19, versus 1Q19, totaling R$3,380 million, mainly due to lower productivity of blast furnace number 3. |

· Slab production cost reached R$2,201/t in 2Q19, 6.8% higher than in 1Q19 fueled by higher spending on iron ore driven by a sharp price increase in the period, as well as by the scheduled stoppage of blast furnace number 3, which reduced slab production and increased the consumption of reducers.

· Adjusted EBITDA reached R$225 million in 2Q19, 34% lower than in 1Q19, driving the EBITDA Margin to 6.2% in 2Q19. The efficiency gains expected after the scheduled shutdown of blast furnace number 3 should be felt partially as of 3Q19 and fully as of 4Q19, taking the profitability of the business unit to its historical standard.

CSN’s Mining Results

In 2Q19, the perception of a tight balance between supply and demand was confirmed. While the Chinese steel production continued accelerating, with a 14% growth in the quarter, the supply already compromised after the accident in Brumadinho was heavily impacted by rainfall in northern Brazil and a cyclone in Australia. In this context, steel ended 2Q19 with an average of US$100.1/dmt (Platts, Fe62%, N. China), 21% higher than in 1Q19.

As for maritime freight, the BCI-C3 (Tubarão-Qingdao) route had an average of US$15.55/wmt in 2Q19, up by 11.6% compared to the previous quarter, influenced by the gradual increase in shipments.

· In 2Q19, CSN’s iron ore production reached 8.3 million tons, 23% higher than in 1Q19, driven by filtration operations and productivity gains. Iron ore purchases reached 1.8 thousand tons in 2Q19, increasing by 17% versus 1Q19.

· Iron Ore sales reached 10.1 million tons in 2Q19, 25% higher than the volume recorded in 2Q18, of which 1.1 million tons were sold to the Presidente Vargas Steelworks and the remaining was sold in Asian and European markets.

1. DESCRIPTION OF BUSINESS

Companhia Siderúrgica Nacional “CSN”, also referred to as “the Company” or “Parent 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, associates and joint ventures 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). Accordingly, the Company reports its information to the Brazilian Securities and Exchange Commission (CVM) and the U.S. Securities and Exchange Commission (SEC).

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 aimed at gaining markets and providing excellent services to end consumers. Its steel is used in home appliances, civil construction and automobile industries.

· Mining:

The production of iron ore is developed in the city of Congonhas, State of Minas Gerais, by subsidiary CSN Mineração.

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 transportation is carried out through Terminal de Carvão e Minérios do Porto de Itaguaí – (“TECAR”), a solid bulk terminal, one of the four terminals that comprise the Itaguaí Port, in State of Rio de Janeiro. Imports of coal and coke are also carried out through this terminal by providing services to CSN’s steel segment. The Company´s mining activities also comprise exploitation of tin in the State of Rondônia, to supply the needs of the UPV. The surplus of these raw materials is sold to subsidiaries and third parties.

The Company's mining activities utilize tailings dams for which all appropriate measures are taken to mitigate the risks inherent to the handling and disposal of the tailings and to comply with current environmental legislation. It is important to reiterate that operating without dependence on these dams is a priority in our mining activities, for which investments of around R$ 250 million in dry stacking technology have already been made. In this context, it is expected that CSN Mineração will be fully processing the tailings in the dry process by the end of 2019, subject to revision of projects and expected deadlines, proper operation of equipment and unforeseen delays. As a consequence of these measures, decommissioning of dams is the natural way of processing dry tailings.

All of our dams, both mining and hydroelectric dams, are positively certified and comply with the environmental legislation in force.

· Cement:

CSN entered the cement market boosted by the synergy between this activity and its existing businesses. Next to the Presidente Vargas Steelworks (UPV) in Volta Redonda (RJ), the Company installed a new business unit that produces CP-III type cement using slag produced by the UPV’s blast furnaces. It also exploits limestone and dolomite at the Arcos unit in the State of Minas Gerais, to meet the needs of the UPV and of the cement plant. Additionally, the operation clinker production line is located in Arcos/MG. As a result, the Company is self-sufficient in the production of cement, with an installed capacity of 4.7 million tons per year.

3. ADOPTION OF NEW ACCOUNTING PRACTICES

· IFRS 16/CPC 06(R2) - Leases

The Company applied as of January 1, 2019, IFRS 16/CPC 06 (R2) – Leases.

As a result, the Company started to recognize in its financial statements the right to use the assets and liabilities of lease arrangements.

The Company opted to apply the modified retrospective approach, recognizing the cumulative effect as an adjustment in the opening balance. For existing contracts on the date of the initial adoption, the right to use was recognized for the amount equal to the lease liability, which was measured at the present value of the future fixed obligations provided for in the contract.

The company applied the exemption provided for in the standard for the non-recognize of the right of use and lease liability for contract with a term of not more than twelve months and that has a low value.

The present value of the lease liabilities was calculated using the interest rate implicit in the contracts and in and in its absence, the Company chose to use the average rate of fundraising.

The effects of the recognition of the standard can be observed in notes 10 and 14.a.

1. Refers to the excess of judicial deposit originated by the 2009 REFIS (Tax Debt Refinancing Program).

2. Refers mainly to PIS / COFINS, ICMS recoverable and income and social contribution taxes to be offset. On September 20, 2018, the writ of mandamus and special appeal filed in 2006, in which CSN and Federal Union were parties, related to the discussion about the non-inclusion of ICMS in the calculation base of PIS and COFINS, confirmed the CSN's right to offset the amounts unduly paid under these taxes from 2001 to 2014.

3. Refers a payment of freight expenses and maritime insurance over revenues didn’t recognized.

4. Long-term iron ore inventories that will be used after the construction of the processing plant, which will produce pellet feed, expected to start operating in the second half of 2020.

5. This is a fixed amount, certain and due, arising from the res judicata favorable decision to the Company, which is irreversible and irrevocable, to apply the STJ's consolidated position on the subject, which culminated in the conviction of Eletrobrás to the payment of the correct interest and monetary adjustment of the Compulsory Loan. The res judicata decision, as well as the certainty about the amounts involved in the liquidation of the sentence (judicial procedure to request the satisfaction of the right), allowed the conclusion that the entry of this value is certain.

· TRANSNORDESTINA LOGÍSTICA S.A. (“TLSA”)

It is in pre-operational phase and will continue as such until the completion of Railway System II. The approved schedule, which estimated the completion of the work by January 2017, is currently under review and discussion with the responsible agencies; however, Management believes that new deadlines for project completion will not have material adverse effects on the expected return on the investment. After analyzing this matter, Management considered as appropriate the use of the accounting basis of operational continuity (going concern) of the project in the preparation of its financial statements.

The assumptions used to evaluate the impairment test in December 2018 remain valid and there is no event to justify records of impairment in the first quarter.

In addition, the political rights in Usiminas will continue to be suspended until the Company reaches the limits established in the TCD.

• Share market price risks

The Company is exposed to the risk of changes in the price of the shares due to the investments, valued at fair value through profit or loss that have their prices based on the market price.

III - Financial risk management:

The Company follows risk management strategies, with guidelines in relation to the risks incurred by the company. The nature and general position of financial risks is regularly monitored and managed to assess the results and the financial impact on cash flow. The credit limits and hedge quality of the counterparties are also periodically reviewed.

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

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

13.a) Foreign exchange rate and interest rate risks:

· Foreign exchange rate risk:

The exposure arises from the existence of assets and liabilities denominated in Dollar or Euro, since the Company's functional currency is substantially the Real and is denominated natural currency hedge. The net exposure is the result of offsetting the natural currency exposure by hedging instruments adopted by CSN.

· Cash flow hedge accounting

Beginning November 1, 2014, the Company designate cash flow hedging relationships to hedge highly probable future cash flows against US dollar fluctuations.

In order to better reflect the accounting impacts of this foreign exchange hedging strategy on the Company’s results, CSN designated part of its US dollar-denominated liabilities as a hedging instrument of its future exports. As a result, foreign exchange differences arising from designated liabilities will be temporarily recognized in shareholders’ equity and recognized in profit or loss when such exports are carried out, allowing the concurrent recognition of the dollar fluctuations on liabilities and on exports. The adoption of this hedge accounting does not entail entering into any financial instrument. As of June 30, 2019, US$1,600,045 in exports to be carried out from July 2019 until February 2023 are designated.

In order to support the aforementioned designations, the Company prepared formal documentation indicating how the hedge designation is aligned with CSN's objective and risk management strategy, identifying the hedging instruments used, the hedge object, the nature of the risk to be hedged and demonstrating the expectation of high effectiveness of the designated relations. Debt instruments have been designated in amounts equivalent to the portion of future exports. Therefore, the exchange variation of the instrument and the object are similar. According to the Company's accounting policy, continuous evaluations of prospective and retrospective effectiveness should be carried out, comparing the amounts designated with the amounts expected and approved in the Management's budgets, as well as the amounts exported.

Through hedge accounting, the exchange gains and losses on debt instruments will not immediately affect the Company’s profit or loss except to the extent that exports are carried out.

· Hedge of net investment in foreign operation

CSN has a natural currency exposure in Euros substantially arising from a borrowing taken by a foreign subsidiary with functional currency in Reais, for the acquisition of investments abroad where the functional currency is Euro. Such exposure arises from translating the balance sheets of these subsidiaries for consolidation into CSN, where the exchange difference on the borrowings affected the statement of income, in the finance income and costs line item, and the exchange difference on the net assets of the foreign operation directly affected the shareholder’s equity, in other comprehensive income.

As from September 1, 2015, CSN began to adopt the net investment hedge to eliminate such exposure and cover future fluctuations of the Euro on such borrowings. Non-derivative financial liabilities were designated, represented by borrowing agreements with financial institutions in the amount of € 120 million. The account balances as of June 30, 2019 are as follows:

In its corporate structure the Company has foreign subsidiaries whose profits are subject to income tax in the countries where they were established at rates lower than those prevailing in Brazil. In the period from 2014 and 2019, these foreign subsidiaries generated profits amounting to R$1,150,443. If the tax authorities understand that these profits are subject to additional taxation in Brazil in respect of income tax and social contribution, these, if due, would total approximately R$366,847.

The Company, based on its legal counsel’s opinion, assessed as possible the likelihood of loss in the event of challenge by the tax authorities and, therefore, no provision was recognized in the financial statements.

A sensitivity analysis of tax credit was performed considering a variation of macroeconomics assumptions, operating performance and liquidity events. In this way, considering the results of studies performed, which indicates that it is probable that there will be taxable income to use the deferred income and social contribution taxes balance, we estimate the realization installments of deferred assets, detailing year by year for the first five years.

The estimated recovery of deferred tax assets of IRPJ and CSLL, is as follows:

In millions of reais |  | Consolidated | Parent Company

2021 |  | 721 | 721

15.d) Impairment test - Deferred taxes

The Company's management constantly evaluates the ability to use its tax credits. In this direction, CSN periodically updates a technical study to demonstrate if the generation of future taxable profits support the realization of tax credits and, consequently support the realization of tax credits, the maintenance on the balance sheet or the constitution of a provision for loss in the realization of these credits.

This study is prepared at Entity level, in accordance with the Brazilian tax legislation, and is performed considering the Parent company’s projections, which is the entity that generates a significant amount of tax credits, mainly, temporary differences. The parent company covers the following businesses:

• Steel Brazil (steel); and

• Cement;

The deferred tax assets on tax losses and temporary differences refers mainly to the following:

| Nature | Description
| Tax losses | The Company incur tax losses at the parent company level, because of financial expenses over its leverage, since it holds substantially all loans and financings of CSN group and presented a taxable income in 2018.
Temporary differences | Foreign exchange differences | Since 2012 the Company opted for the taxation of exchange differences on a cash basis. As a result of the cash basis tax treatment, taxes are only due, and expenses are only deductible at the time of debt settlement.
Losses on Usiminas shares | The losses on Usiminas shares are recognized on an accrual basis, but the taxable event will occur only at the time of divestment.
Other provisions | Various accounting provisions are recognized on an accrual basis, but their taxation occurs only at the time of its realization, such as provisions for contingencies, impairment losses, environmental liabilities, etc.

The study prepared is based on the Company business plan of on a long-term basis, reasonably estimated by management and considered several scenarios which vary according to different macroeconomic and operating assumptions.

The model for projection of taxable profit considers two main indicators:

· Pre-Tax Profit, reflecting our projected EBITDA plus depreciation, other income and expenses and financial income (expenses); and

· Taxable Profit, which is our pre-tax profit plus (minus) expenses and income items that are taxable at a time different from the time obtained on an accrual basis (temporary differences).

In addition, a sensitivity analysis of tax credits utilization considering a variation in macroeconomic assumptions, operational performance and liquidity events took place.

A significant aspect to be considered in the analysis is the fact that CSN has presented recent tax losses mainly due to the deterioration of the Brazilian political and macroeconomic environment, as well as the growth of its financial leverage. These two aspects combined led to an unbalance between the financial and operating results of the Parent company.

Within this context, the Company works with a business plan to rebalance between the financial and operating results of the Parent company, whose main measures are:

· Expansion of disinvestment efforts;

· Reduction of financial leverage;

· Improvement in operating results due to increased sales volume, better prices of its products and efficiency in controlling production costs and

· Reprofiling of the Parent company's indebtedness, with negotiations to extend the amortization periods and decentralization of debt through redirection of contracts to subsidiaries according to the nature and application of resources.

With the measures already in execution, the Company's management expects to retake high profitability rates. Accordingly, management considers that the gradual recognition of tax credits, using at first a time of projections of less than 10 years, better reflects the expectation of utilization of the credits recognized in the Company's tax books. Because of the study, the Company reversed as of June 30, 2019 R$ 1,615,279 of the loss recorded in previous years, with a balance of deferred fixed assets recognized in the amount of R$ 2,512,459 in the Parent Company.

· Adjusted EBITDA

Adjusted EBITDA is the principal measurement through which the chief operating decision maker assesses the segment performance and the capacity to generate recurring operating cash, consisting of profit for the year less net finance income (expenses), income tax and social contribution, depreciation and amortization, equity in results, results of discontinued operations and other operating income (expenses), plus the proportionate EBITDA of joint ventures.

Even though it is an indicator used in segment measurement, EBITDA is not a measurement recognized by accounting practices adopted in Brazil or IFRS, it does not have a standard definition, and may not be comparable with measurements using similar names provided by other companies.

As required by IFRS 8, the table below shows the reconciliation of the measurement used by the chief operating decision maker with the results determined using the accounting practices:

26. EMPLOYEE BENEFIT

The information related to employee benefits didn’t change compared to that disclosed in the Company’s financial statements as of December 31, 2018. Accordingly, management has decided not repeat them in this interim financial information.

Actuarial calculations are updated at the end of each year by external actuarial and presented in the financial statements in accordance with CPC 33(R1) – Employee benefits and IAS 19 – Employee Benefits. For the health plan there was a sporadic update dated June 30,2019.

Refers to the health plan created on December 1, 1996 exclusively to cover former employees retired until March 20, 1997 and their respective legal dependents. Since then, the health plan does not allow the inclusion of new participants. The plan is sponsored by CSN.

27. INSURANCE

Aiming to properly mitigate risk and in view of the nature of its operations, the Company and its subsidiaries have taken out several different types of insurance policies. Such policies are contracted in line with the Risk Management policy and are similar to the insurance taken out by other companies operating in the same lines of business as CSN and its subsidiaries. The risks covered under such policies include the following: Domestic Transportation, International Transportation, Life and Casualty, Health, Vehicles Fleet, D&O (Civil Liability Insurance for Directors and Officers), General Civil Liability, Engineering Risks, Named Peril, Export Credit, Surety Bond and Port Operator’s Civil Liability.

In 2019, after negotiation with insurers and reinsurers in Brazil and abroad, an insurance policy was issued for the contracting of a policy of Operational Risk of Property Damages and Loss of Profits, with effect from March 31, 2019 to March 31, 2020. Under the insurance policy, the LMI (Maximum Limit of Indemnity) is US$600 million and deductibles in the amount of US$385 million for material damages and 45 days for loss of profits and covers the following Company’s units and subsidiaries: Presidente Vargas Steelworks, CSN Mineração and Sepetiba Tecon. Management understands that the policies covers its assets and the risks to which the Company is subject.

The risk assumptions adopted, given their nature, are not within the scope of an audit of the financial statements, consequently not audited by our independent auditors.

COMMENTS ON THE PERFORMANCE OF BUSINESS PROJECTIONS

Projections

The Company clarifies that the information disclosed in this item represents a mere estimate, hypothetical data and cannot be interpreted as a promise of performance by the Company and/or its Management. The projections listed below include market variables that are not under the Company’s control and, therefore, may change.

#

# a) Purpose of Projection

CSN estimates an adjusted annualized EBTIDA close to R$8,5 billion for 2019.

CSN estimates a leverage measured by the ratio of net debt to adjusted EBITDA close to 3.0 times at the end of 2019.

CSN estimates iron ore sales volume to 40 million of tons (Mton) in 2019.

CSN estimates iron ore production volume at 33 million of tons (Mton) in 2019, 33 Mton in 2020, 31.2Mton in 2021, 36.6Mton in 2022 and 38Mton in 2023.

#

# b) Period and validity term of the projection.

For the year 2019, is projected an EBITDA close to R$8.5 billion. In turn, the validity term of the presented projection ends with the results being disclosed for the fiscal year ended December 31, 2019, that will be available to the market within the period established by the local authority.

In December 2019, CSN estimates a leverage measured by the ratio of net debt to adjusted EBTIDA close to 3.0 times, that will be available to the market at the end of 2019 period.

The projected period of iron ore sales comprehends the 2019 year and the annual volume will be available to the market in the financial statements to be published.

CSN estimates annual volume of iron ore production from 2019 to 2023 and the annual volumes will be available to the market in the financial statements to be published in each of the years.

# c) Assumptions of the projection, indicating which can be influenced by the issuer’s management and which are beyond its control.

All assumptions mentioned below are subject to the influence of external variables, which are beyond the control of the Company’s management. Therefore, in case of relevant changes in these assumptions, the Company may revise its estimates mentioned below, modifying them in comparison with those originally presented.

Adjusted EBITDA

The assumptions used to project the adjusted EBITDA close to R$8.5 billion for 2019, we estimate in the year iron ore prices levels (Platts – 62% Fe) above those estimated in 2018, when the reference indices close in average of US$ 69,46/ton. We consider it more feasible to maintain price levels (Platts - 62%) above US$ 100 / ton in the second half, improving the EBITDA from this business unit. Regarding the steel industry, we consider increasing volumes and stable prices, but higher raw material prices than initially estimated.

Quarterly Financial Information - June 30, 2019 – CIA SIDERURGICA NACIONAL | Version: 1

Leverage

The assumptions used for the leverage measured by the ratio of net debt to adjusted EBITDA close to 3.0 times over 6 months based on an increase of the adjusted EBITDA, resulting in a higher generation of free cash flow and lower net debt, leading to a substantial reduction of the indicator.

Iron Ore Sales Volume

Iron ore sales volume in 2019 considers domestic and foreign sales, in line with the perspective of third-party production and purchase of ore.

Volume of Iron Ore Production

The volume of ore production considers our mining plan between 2019 and 2023, with an increase in pellet feed production, in line with the investment projects announced through Material Fact and Corporate Presentation with the market.

If the issuer has disclosed, in the last 3 fiscal years, projections over the progress of its indicators:

a) Inform which were being replaced by new projections and which were being repeated.

Estimates maintained:

CSN estimates a leverage measured by the ratio of net debt to adjusted EBITDA close to 3.0 times at the end of 2019.

CSN estimates iron ore production volume at 31.2Mton in 2021, 36.6Mton in 2022 and 38Mton in 2023.

Estimates replaced:

We adjusted the annualized adjusted EBTIDA estimate from R$ 7.5 billion to R$ 8.5 billion in 2019, mainly due to the higher than expected iron ore price (Platts - 62%).

We adjusted the estimated iron ore production from 31.5 Mton to 33 Mton in 2019 and from 30.7 Mton to 33 Mton in 2020.

CSN adjusted its estimated iron ore sales volume from 38 to 40 million tons (Mton) in 2019, due to higher availability of third party iron ore for sale and good performance in own production.

# b) In relation to the projections for periods that have already occured, compare the projection data with the performance indicators, clearly indicating the reasons that led to deviations in the projections.

CSN estimated leverage as measured by net debt to adjusted EBITDA close to 3.5x at the end of the first half of 2019, when we reached 3.65x, materially within our initial estimates that were reached at the beginning of the third quarter. with the second prepayment of iron ore.

Report on review of the interim information (ITR)

To the Shareholders, Directors and Management of

Companhia Siderúrgica Nacional

São Paulo - SP

Introduction

We have reviewed the accompanying individual and consolidated interim financial information of Companhia Siderúrgica Nacional (“Company”), identified as Parent and Consolidated, respectively, included in the Interim Financial Information Form (ITR) for the quarter ended June 30, 2019, which comprises the balance sheet as of June 30, 2019 and the related statement of profit and loss and statement of comprehensive income (loss) for the three and six-month periods then ended, and the statement of changes in equity and statement of cash flows for the six-month period then ended, including a summary of significant accounting policies and other explanatory notes.

Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with Technical Pronouncement CPC 21 (R1) - Interim Financial Reporting and IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the presentation of such information in accordance with the standards issued by the Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of Interim Financial Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the standards on auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the individual and consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the Interim Financial Information Form (ITR) referred to above is not prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34 applicable to the preparation of interim financial information and presented in accordance with the standards issued by the Brazilian Securities and Exchange Commission (CVM).

Emphasis of matter

Ability of the jointly-controlled subsidiary Transnordestina Logística S.A. to continue as a going concern

We draw attention to note 9.c) to the interim financial information, which describes the percentage of completion of the new railway network by the jointly-controlled subsidiary Transnordestina Logística S.A. (TLSA), currently under construction and originally scheduled to be completed by January 2017, is currently being revised and discussed by the relevant regulatory bodies. The completion of the work under the project (and consequent start of operations) is contingent upon receiving ongoing financial contribution

Page 96

from TLSA´s shareholders and third parties. These events and conditions, together with other issues described in note 9.c) to the interim financial information, indicate the existence of significant uncertainty that may raise significant doubt as to TLSA´s ability to continue as a going concern. Our conclusion is not qualified regarding this matter.

Other matters

Interim statement of value added

We have also reviewed the individual and consolidated statements of value added (DVA) for the six-month period ended June 30, 2019, prepared under the responsibility of the Company’s management, the presentation of which is required by the standards issued by the Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of interim financial information and considered supplemental information by IFRS, which does not require the presentation of a DVA. This interim financial information was subject to the same review procedures described above and, based on our review, nothing has come to our attention that causes us to believe that it was not fairly presented, in all material respects, in relation to the individual and consolidated interim financial information taken as a whole.
