CSN’s Consolidated Results

· Net revenue totaled R$3,844 million in 1Q16, 5% up on 4Q15 and 4% down on the same period last year. Regarding 4Q15, the increase was due to the higher sales volume in the steel and mining segments, offsetting the decrease in the average steel and mining prices, which suffered the additional impact of BRL appreciation. Compared with 1Q15, the reduction was a result of lower sales volume in the steel segment.

· COGS amounted to R$2,918 million, in line with the previous quarter and 4% less than in 1Q15. The year-on-year reduction was mainly due to lower steel and mining segments unit costs.

· First-quarter gross profit came to R$926 million, 21% more than in 4Q15, while the gross margin widened by 3p.p. to 24%. In comparison with 1Q15, gross profit fell by 6% and the gross margin narrowed by 1p.p., from 25% to 24%.

· Selling, general and administrative expenses totaled R$611 million in 1Q16, 12% and 49% up on 4Q15 and 1Q15, respectively, chiefly due to higher freight (related to distribution costs), due to the increase in iron sales and the higher CIF sales model, and personnel expenses.

· Other operating income (expenses) was a net expense of R$127 million in 1Q16, versus expense of R$214 million in 1Q15. Most of the amount in question referred to expenses with labor provisions and judicial deposits. The positive result registered in 4Q15 was due to the Business Combination effect in the mining segment.

· The proportional net financial result was negative by R$968 million in 1Q16, due to: i) financial expenses (excluding the exchange variation) of R$890 million; ii) the negative exchange variation result of R$329 million; and iii) financial revenue of R$251 million.

· CSN’s equity result was a positive R$45 million in 1Q16, versus a negative R$55 million in 4Q15 and a positive R$398 million in 1Q15, chiefly due to MRS’s equity result in the 1Q16 and 4Q15, and Namisa’s equity result in the 1Q15. The table below presents a breakdown of this item:

Share of profits (losses) of investees (R$ Million) | 1Q15 | 4Q15 | 1Q16 | Change

Share of profits (losses) of investees | 398 | (55) | 45 | - | (89%)

· CSN recorded a first-quarter net loss of R$831 million, versus net income of R$2,371 million in 4Q15 and net income of R$392 million in 1Q15. The worsening in this result, compared with 4Q15, is explained by the gains registered with the conclusion of the mining segment Business Combination last quarter. Regarding 1Q15, the lower result was due to the exchange rate variation result and taxes payment.

(-) Proportionate EBITDA of Joint Ventures | 73 | 155 | 107 | (31%) | 48%
Adjusted EBITDA | 911 | 686 | 733 | 7% | (20%)

· Adjusted EBITDA amounted to R$733 million in 1Q16, 7% up on the previous quarter, but 20% down on 1Q15, accompanied by an adjusted EBITDA margin of 18.1%, 1.1 p.p. more than in 4Q15, but 3.4% less than in 1Q15.

¹ The adjusted EBITDA margin is calculated as the ratio between Adjusted EBITDA and Adjusted Net Income, which considers stakes of 60% in Namisa, 33.27% in MRS and 50% in CBSI until November 2015 and stakes of 100% in Congonhas Minérios, 37.27% in MRS and 50% in CBSI as of December 2015.

Debt

The adjusted amounts of EBITDA, Debt and Cash included the stakes of 60% in Namisa, 33.27% in MRS and 50% in CBSI until November 2015 and the stakes of 100% in Congonhas Minérios, 37.27% in MRS and 50% in CBSI, as of December 2015, as well as financial investments used as collateral for exchange operations on the BM&FBovespa. On March 31, 2016, consolidated net debt totaled R$26,654 million, while the net debt/EBITDA ratio, was 8.67x based on LTM adjusted EBITDA.

Foreign Exchange Exposure

Net foreign exchange exposure generated by the difference in dollar-denominated assets and liabilities, contracted derivatives and hedge accounting booked by CSN totaled US$115 million on March 31, 2016. The derivatives contracted form a long USD position achieved through the purchase of NDFs (Non-Deliverable Forwards). The hedge accounting adopted by CSN correlates the projected export flows in dollars with part of the future debt maturities in the same currency. As a result, the exchange variation of part of dollar-denominated debt is temporarily recorded under shareholder’s equity, being transferred to the income statement when the dollar revenue from these exports is received.

¹As of the conclusion of the Business Combination, through asset transfers to Congonhas Minérios, CSN has been consolidating 100% of the new Company’s cash. As a result, a proportional view of foreign exchange exposure is no longer necessary.

²Proportional foreign exchange exposure includes the 60% stake in Namisa and excludes the stake in MRS.

³IFRS foreign exchange exposure on March 31, 2015 includes the 100% stake in Congonhas Minérios and excludes the stake in MRS.

Capex

CSN invested R$330 million in 1Q16 in the following projects:

· Investments in the new clinker kiln in Arcos/MG, which will permit the Cement segment to reach competitive margins and scale gains in the Southeast region as a result of the clinker production self-sufficiency.

· Revamp of the coke batteries, reducing imported coke needs and improving the fuel rate.

· Other projects designed to improve the environmental performance of the Presidente Vargas Plant and current investments in other operations.

Of total investments, R$54 million went to spare parts and R$155 million to current investments.

Working Capital

In order to calculate working capital, CSN adjusts its assets and liabilities as shown below:

· Accounts Receivable: Excludes Dividends Receivable, Advances to Employees and Other Credits (Note 5 of the financial statements).

· Inventories: Includes Estimated Losses and excludes Spare Parts which is not part of the cash conversion cycle, and will be subsequently booked under Fixed Assets when consumed. (Note 6 of the financial statements);

· Recoverable Taxes: Composed only of Income (IRPJ) and Social Contribution (CSLL) Taxes included in Recoverable Taxes (Note 7 of the financial statements);

· Taxes Payable: Composed of Taxes Payable under Current Liabilities plus Taxes in Installments (Note 13 of the financial statements);

· Advances from Clients: Subaccount of Other Liabilities recorded under Current Liabilities (Note 13 of the financial statements);

· Suppliers: Includes Forfaiting and Drawee Risk (Note 11 of the financial statements).

As a result, working capital applied to the Company’s business totaled R$3,077 million in 1Q16, R$90 million less than in 4Q15, chiefly due to the R$472 million reduction in inventories, while accounts receivable increased by R$245 million. On a same comparison basis, the average receivable period increased by 6 days, while payment periods and inventory turnover fell by 4 and 14 days, respectively.

Results by Segment

The Company maintains integrated operations in five business segments: steel, mining3, logistics, cement and energy. The main assets and/or companies comprising each segment are presented below2:

¹ Namisa’s former assets.

² As of 2013, the Company ceased the proportional consolidation of its jointly-owned subsidiaries Namisa, MRS and CBSI. For the purpose of preparing and presenting the information by business segment, Management opted to maintain the proportional consolidation of its jointly-owned subsidiaries, as historically presented. For the reconciliation of CSN’s consolidated results, these companies’ results are eliminated in the "corporate/elimination expenses" column.

³ In order to report the Company’s 2015 results, after the combination of CSN’s mining assets (Casa de Pedra, Namisa and Tecar), the consolidated result includes all this new company’s information.

Mining

In 1Q16, the seaborne iron ore market was positively impacted by the greater availability of credit and the recovery of construction activities in China, led by investments in new real estate projects. The improvement in demand led to higher prices and healthier margins for the local steel producers, as well as encouraging the build-up of inventories. In addition, seasonal factors, such as higher rainfall in Australia and Brazil, as well as the rigorous Chinese winter, played an important role in reducing the iron ore supply base. As a result, iron ore prices moved up by 3.5% over the previous quarter, averaging US$48.30/dmt (Platts, 62% Fe, N. China).

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, 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 (BM&F BOVESPA) and on the New York Stock Exchange (NYSE). Accordingly, the Company reports its information to the Brazilian Securities Commission (CVM) and the U.S. Securities and Exchange Commission (SEC).

The Group's main operating activities are divided into five (5) operating 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 the 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 operations in the United States, Portugal and Germany, all of them are in line with the plan to achieve new markets and perform excellent services for final consumers. Its steel has been 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.

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 accomplished by Terminal de Carvão e Minérios do Porto de Itaguai - TECAR, a solid bulk terminal, one of the four terminals that compose the Port of Itaguai, located in Rio de Janeiro. Imports of coal and coke are held through this terminal and directed to the steel industry of CSN.

From November 30, 2015 the Company has transferred its mining assets, together with its logistical infrastructure, which includes the mine Casa de Pedra and the right to operate the terminal TECAR, to its subsidiary Congonhas Minérios S.A. In the new structure Congonhas Minérios S.A. has taken control over Nacional Minérios S.A. (NAMISA) through a business combination transaction.

The Company´s mining activities also comprises tin exploitation, which is based in the State of Rondônia, this facility is engaged to supply the needs of UPV, with the excess of these raw materials being sold to subsidiaries and third parties.

· Cement:

CSN entered in the cement market boosted by the synergy between this new activity and its existing businesses. Next to the Presidente Vargas Steelworks (UPV) in Volta Redonda (RJ), it is installed a new business unit: CSN Cimentos, which produces CP-III type of cement by using slag produced by the UPV blast furnaces in Volta Redonda. It also explores limestone and dolomite at the Arcos unit, located in the State of Minas Gerais, to satisfy the needs of UPV as of the cement plant.

· Hedge accounting – cash flow

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

In order to better reflect the accounting impacts of this foreign exchange hedging strategy on its profit, CSN designated part of its US dollar-denominated liabilities as a hedging instrument of its future exports. As a result, foreign exchange differences arising on translating the designated liabilities has been temporarily recognized in shareholders’ equity and allocated to profit or loss when such exports are carried out, which will allow recognizing the US dollar impact on liabilities and exports concurrently.

The table below shows a summary of the hedging relationships as of March 31, 2016:

(*) The effect on the financial result was recorded in net foreign exchange rates.

(1) During the designation on August 2015, we reviewed the future export projections and identified that the amount of US$ 9 million designated previously were not highly probable due to Platt’s quotation reduction. Therefore, the hedge relationship was discontinued from August 2015. The exchange rate of the effective period remains recorded in Stockholders' Equity until the time of debt settlement.

In the hedging relationships described above, the amounts of the debt instruments were fully designated for equivalent iron ore export portions.

· Net investment hedge in foreign subsidiaries

CSN has foreign exchange exposure in Euros arising from a loan made by a foreign subsidiary with functional currency in Reais, for the acquisition of investments abroad whose functional currency is Euro. Such exposure arises from converting the balance sheets of these subsidiaries for consolidation in CSN, and the exchange rate of the loans affected the income statement in the financial result item and the exchange variation of the net assets of the foreign operation directly affected the equity in other comprehensive income.

As from September 1st, 2015 CSN began to adopt hedge of net investment to eliminate exposure in order to cover future fluctuations of the Euro on such loans. Non-derivative financial liabilities have been designated represented by loan agreements with financial institutions in the amount of € 120 million. The carrying amounts as of March 31, 2016 are:

|  |  |  |  |  |  |  |  |  |  |  | 03/31/2016

(*) The Company taxes the foreign exchange differences on a cash basis to calculate income tax and social contribution.

The Company has overseas subsidiaries in its corporate structure, for which profits are taxed at income tax in the countries where they are domiciled by lower rates than those prevailing in Brazil. From 2011 to 1st quarter 2016 some abroad subsidiaries generated profits amounting to R$4,039,308. If for some reason tax authorities understand that these profits have already been distributed, the additional taxation in Brazil would amount approximately to R$1,373,365 in income tax and social contribution.

The Company, based on its legal counsel’s opinion, assessed the likelihood of loss in a potential claiming by tax authorities which resulted in a possible risk of loss and, therefore, no provision was recognized in the financial statements.

14.c) Income tax and social contribution recognized in shareholders' equity:

Adjusted EBITDA is the measurement based on 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 (costs), income tax and social contribution, depreciation and amortization, equity in results of affiliated companies, and other operating income (expenses), plus the proportionate EBITDA of joint ventures.

Even though it is an indicator used in segment performance 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 entities.

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:

|  |  |  | Consolidated
|  | 03/31/2016 |  | 03/31/2015

Proportionate EBITDA of joint ventures |  | 107,316 |  | 72,608
Adjusted EBITDA (*) |  | 732,665 |  | 911,150

(*) The Company discloses its adjusted EBITDA net of its share of investments and other operating income (expenses) because it understands that these should not be included in the calculation of recurring operating cash generation.

26. 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 CSN 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 Coverage, Fleet Vehicles, D&O (Civil Liability Insurance for Directors and Officers), General Civil Liability, Engineering Risks, naming Risks, Export Credit, warranty and Port Operator’s Civil Liability.

In 2015, 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 September 30, 2015 to September 30, 2016. Under the insurance policy, the LMI (Maximum Limit of Indemnity) is US$600 million and covers the following units and subsidiaries of the Company: Presidente Vargas steelworks, Congonhas Minérios, Sepetiba Tecon, and CSN Mining. CSN takes responsibility for a range of retention of US$375 million in excess of the deductibles for property damages and loss of profits.

In view of their nature, the risk assumptions adopted are not part of the scope of an audit of the financial statements and, accordingly, were not audited by our independent auditors.

Usiminas

As of March 2016, the Usiminas’ Board of Directors approved a capital increase amounting to R$64,882, through the issuance of 50,689,310 preferred shares. Consequently on April 22, 2016 CSN exercised its right of subscription, paying R$11,603 by 9,064,856 preferred shares.

The Usiminas’ Board of Directors approved in April 2016 an increase in its share capital amounting to R$1,000,000, through the issuance of 200,000,000 new common shares, with a deadline for exercising the preferential right to acquire the said shares up to May 23, 2016.

The election was made possible through the flexibility and exceptional decision from CADE (Administrative Council for Economic Defense) in relation to the TCD (Performance Commitment Agreement) signed by CSN and the said Council in 2014. The mentioned decision´s flexibility was approved by the majority of CADE's Board at the meeting on April 27,2016.

• Conduct Adjustment Agreement (UPV)

On April 12, 2016 CSN entered into a Conduct Adjustment Agreement with the Environment Department of the State of Rio de Janeiro, the Environment Control Commission of the State of Rio de Janeiro and the Environment Institute of the State of Rio de Janeiro (INEA) comprising the resolution of all pending environmental issues related to the Presidente Vargas Steelworks (UPV), thereby ensuring the continuation of its operations.

Under the agreement, CSN has committed to invest, up to September 2017, the amount of R$178 million in improvements on production processes. Besides that, the company has also committed to pay to INEA the amount of R$ 22million, to be used in environmental programs in region of Volta Redonda.

These related compensations were substantially recorded as provision for contingencies as of March 31, 2016. The other values do not affect the provision for risks, since these are CSN's commitments to invest in improvements to its operating assets.

REPORT ON REVIEW OF INTERIM FINANCIAL INFORMATION

To the Board of Directors and Shareholders of

Companhia Siderúrgica Nacional

São Paulo – SP

Introduction

We have reviewed the accompanying individual and consolidated interim financial information of Companhia Siderúrgica Nacional (the “Company”), identified as Parent and Consolidated, respectively, included in the Interim Financial Information Form (ITR), for the three-month period ended March 31, 2016, which comprises the balance sheet as of March 31, 2016 and the related statements of income, comprehensive income, changes in equity and cash flows for the three-month period then ended, including the explanatory notes.

The Company’s Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with technical pronouncement CPC 21 (R1) Interim Financial Information and international standard 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 the 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 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 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 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 referred to above was not prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34, applicable to the preparation of Interim Financial Information (ITR), and presented in accordance with the standards issued by the CVM.

Emphasis of Matter

The individual and consolidated corresponding values, related to the cash flow statement for the three-month period ended march 31, 2015 are being restated accordingly to the matter described at note 2.d).

Other Matters

We have also reviewed the individual and consolidated statements of value added (DVA) for the three-month period ended March 31, 2016, prepared under the responsibility of the Company’s Management, the presentation of which is required by the standards issued by the CVM applicable to the preparation of Interim Financial Information (ITR) and considered as supplemental information for International Financial Reporting Standards IFRSs, which do not require the presentation of DVA. These statements were 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 they were not prepared, in all material respects, consistently with the individual and consolidated interim financial information taken as a whole.

The accompanying individual and consolidated interim financial information has been translated into English for the convenience of readers outside Brazil.
