Economic Outlook The good pace of economic activity and maintenance of the confidence levels over the 2Q17 sustained the more optimistic forecasts for the global economy in 2017. The International Monetary Fund raised its forecast to 3.5% growth in the year. Domestically, the disclosure of the GDP in the 1Q17 put an end to the sequence of eight negative results, confirming the perception that economic growth is beginning to recover from the crisis initiated in the second quarter of 2014. Nevertheless, the worsening of the political crisis in mid May increased the risks of recovery occurring more slowly. Also, political instability has delayed the processing of the reforms, increasing uncertainty about the perspective of stabilization of the public debt. In spite of this, the dollar appreciated only moderately, with the average quotation increasing from R$3.15/US$ in the 1Q17 to R$3.21/US$ in the 2Q17. Inflation continued to fall more quickly than expected, reaching 3.0% cumulatively in the first half of 2017. This has fed the expectation of maintenance of the pace of the benchmark interest rate - Selic cut in the coming meetings of the Copom. According to the Focus Report of Banco Central do Brasil (06/30/17), the expectation is that interest will fall to 8.5%/yr by the end of 2017. Brazilian industry has begun to show the first signs of a recovery. With available data through May, Industrial Production (IBGE) has increased 0.5% in the five-month comparison of this year with the same period in 2016. Industrial sectors with steel intensive consumption had even more significant gains. Capital goods production increased 3.5% and durable goods, 11.0%. In June, industrial business remained confident, however, there was a reduction in the Confidence Index between May and June, impacted by the worsening of the political crisis. 2Q17 Results 2

I) M I N I N G In the 2Q17, iron ore prices decreased significantly in the international market, reduction of approximately 26% in comparison with the 1Q17, with a quarterly average price of US$62.98/t. The already expected increase in the supply of Australian ore, allied to India s increment in exports, due to its reduction of the export tax, and greater availability of Chinese iron ore concentrates, (which resumed production due to the high prices of the previous two quarters), decisively contributed to this prices behavior. On the consumption side, continued good financial results obtained by Chinese steel also helped to maintain the demand for iron ore, even with the inventories in Chinese ports having reached a historical peak in the period, arriving at 145 million tons. In terms of outlook, the optimism observed in the 1Q17 has cooled off, with prices undergoing natural correction due to the supply situation versus demand presented. Additionally, most of the steel plants have looked for better quality ores, seeking to improve productivity and reduce cost, in view of the good prices observed in the steel market. Operational and Sales Performance - Mining In the 2Q17, production volume was 689 thousand tons, stable when compared to 1Q17, which was 681 thousand tons. Sales volume accounted in the 2Q17 was 629 thousand tons, against 643 thousand tons in the 1Q17, basically to the Steel Business Unit. Production and sales volume are shown in the table below: Iron Ore Thousand tons 2Q17 1Q17 2Q16 Change 2Q17/1Q17 1H17 1H16 Chg. 1H17/1H16 Production 689 681 691 1% 1,370 1,392-2% Sales - Third Parties - Domestic Market 33 28 17 18% 61 33 85% Sales - Exports 0 0 177-0 521 - Sales to Usiminas 596 615 593-3% 1,211 1,207 0% Total Sales 629 643 787-2% 1,272 1,761-28% Comments on the Business Unit Results - Mining In the 2Q17, net revenue accounted was R$89.1 million, against R$108.3 million in the 1Q17, a 17.7% decrease, due to a 8.5% decline in the PLATTS iron ore price (62% Fe, CFR China), adjusted for the period of sales price formation of Mineração Usiminas (US$75.6/t in the 2Q17, against US$82.5/t in the 1Q17), by a 2.2% decrease in sales volume and by the average appreciation of 2.2% of the Real against the Dollar in the period of reference for invoicing. In the 2Q17, cash cost per ton was R$73.2/t, against R$61.8/t in the 1Q17, an 18.4% increase, mainly due to the restarting of operations of two plants (Flotation and Eastern Mine), basically with maintenance, contracting and training of personnel. In the 2Q17, Cost of Goods Sold (COGS) was R$53.2 million, against R$53.0 million in the 1Q17. COGS per ton was R$84.0/t, against R$82.0/t in the 1Q17, a 2.4% increase, mainly due to provisions for profits and results sharing (PRS). In the 2Q17, net operating expenses were R$151,0 million positive, against R$42.5 million negative in the 1Q17, an increase of R$193,4 million, mainly due to the recognition of R$201,1 million net of expenses from the Porto Sudeste Agreement, partially compensated by preoperating expenses, for the restarting of operations of two plants, which were re-classified as operating expenses. Additionally, in the 2Q17, the result with the sales of surplus electrical energy was R$0.4 million, against R$0.1 million in the 2Q17. Thus, in the 2Q17, Adjusted EBITDA was R$225,8 million, against R$51.5 million in the 1Q17, a 338,3% increase. Adjusted EBITDA margin was 253,4% in the 2Q17, against 47.6% in the 1Q17. 2Q17 Results 8

Investments (CAPEX) Investments in the 2Q17 were R$4.7 million, against R$2.6 million in the 1Q17, mainly applied to sustaining CAPEX. Agreement with Porto Sudeste On 05/27/15, Mineração Usiminas notified Porto Sudeste do Brasil S.A. (presently named MMX Porto Sudeste Ltda.) about the immediate rescission of the service contract of port operation receiving, handling, stocking and shipment of ore belonging to Mineração Usiminas at the Porto Sudeste Terminal in the Take or Pay and Delivery or Pay modalities by reason of constant nonperformance on the part of Porto Sudeste, of its obligation to conclude and put into operation, as well as by the non-payment of contractual fines. The Company took the necessary measures to safeguard its rights, including an arbitration process, claiming payment of the fines, reimbursement of opportunity costs, in addition to damages foreseen by contract. The aforementioned contract was signed with a five-year term in effect as of the first shipment, initially forecast for April 2012. On 06/06/17, Mineração Usiminas signed an agreement with Porto Sudeste to end the arbitration process, resulting in the cancellation of the aforementioned contract and the waiver of all rights that both parties could still retain in relation to the contract. On the same date, a new contract was also signed for port operation services, which provides that Mineração Usiminas will have the right, but not the obligation, to move a total volume of up to 17.5 million tons of iron ore per year through the port terminal of Porto Sudeste, located in the municipality of Itaguaí, RJ. Porto Sudeste paid R$205.1 million to Mineração Usiminas on 07/12/17. Stake in MRS Logística Mineração Usiminas holds a stake in the MRS Logística through its subsidiary UPL Usiminas Participações e Logística S.A. MRS Logística is a concession that controls, operates and monitors the Brazilian Southeastern Federal Railroad Network (Malha Sudeste da Rede Ferroviária Federal). The company operates in the cargo railway transportation segment, connecting the states of Rio de Janeiro, Minas Gerais and São Paulo, and its core business is transporting, with integrated logistics, general cargo, such as iron ore, finished steel products, cement, bauxite, agricultural products, pet coke and containers.

II) S T E E L Preliminary figures from the World Steel Association show a crude steel production of 836 million tons in the first six months of 2017, a 4.5% growth over the same period in the previous year. There was growth in practically all the main producing countries, and the greater contribution came from China, which registered volume of 419,7 million tons, 4.6% higher when compared to the same period of 2016. Steel consumption in that country has responded to stimuli through infrastructure spending and should once again grow in 2017, according to the forecast from World Steel Dynamics. Chinese exports, increasingly restricted due to the imposition of trade restrictions, were reduced when compared to 2016. The Chinese government announced the cut of around 40 million tons of crude steel production capacity in 2017. This is equivalent to around 85% of the annual goal, which foresees closing of 50 million tons of capacity. Global aversion to investments has made a stronger demand recovery more difficult, thus maintaining the situation of global overcapacity practically unchanged. In Brazil, according to data from the Brazilian Steel Institute (IABr), crude steel production reached 16.7 million tons, a 12.4% increase in the first six months of 2017, with a highlight for the increase in flat rolled steel, which grew 17.0%. In the period, domestic apparent steel consumption of flat steel products was 5.0 million, a 12.9% increase over the same period in 2016. Production - Ipatinga and Cubatão Plants Crude steel production was 769 thousand tons in the 2Q17, against 737 thousand tons in the 1Q17. In the 2Q17, rolled production in the Ipatinga and Cubatão plants totaled 1.0 million tons, 3.6% higher over the 1Q17, which was 965 thousand tons.
