Vale’s performance in 3Q18 – delivering in every meaningful way Chief Executive Officer, Mr. Fabio Schvartsman, commented on the 3Q18 results, “The strong 3Q18 results showcase the structural change in the Chinese iron ore and steel markets. We are the mining company that is best suited to further benefit from the flight to quality given the increasing share of premium products.” He concluded, “We are turning Vale into a very predictable company by delivering sound operational performance, higher price realization, lower costs and rigorous capital allocation.” • In line with our annual production guidance, we reached a record of 104.9 Mt for iron ore in 3Q18, with an improvement in the overall quality of our products that is a unique combination of higher volumes and higher quality. • Our flexible supply chain along with S11D and pellet plants ramp-ups led to another quarterly sales volume record for iron ore and pellets at 98.2 Mt. 3Q18 was also marked by the increase in the share of our premium products, which achieved 79% of total sales. Our pellets volumes reached a record high of 14.3 Mt, supported by our decision to restart the three idle pellet plants. • Iron ore fines and pellets quality premiums reached the record of US$ 11.0/t1 , an increase of US$ 4.2/t, when compared to 3Q17, completely offsetting the decrease in iron ore prices thus showing our ability to cope with changes in the market trend and adding predictability to our performance. • Our strong cash flow generation of US$ 3.1 billion led us to virtually achieve the net debt target of US$ 10 billion. Net debt reduced further, despite the return of US$ 2.4 billion to our shareholders, totaling US$ 10.7 billion in 3Q18, the lowest level since the third quarter of 2009. • 3Q18 results translated into a minimum shareholder remuneration of US$ 1.142 billion. If we deliver the same results next quarter, our minimum dividend related to the second half, according to our policy, will be US$ 2.3 billion, against US$ 1.9 billion in the first half. Chief Financial Officer Mr. Luciano Siani Pires highlighted, “Over the next years we will explore 1 Iron ore premium of US$ 8.6/t and weighted average contribution of pellets of US$ 2.4/t. 3

options for our accumulated free cash flow in a disciplined way. Dividends will be our natural choice based on our new policy, and on top of dividends, we will pursue: (i) extraordinary dividends or buybacks, (ii) organic growth opportunities, such as the recently approved Salobo III project, (iii) bolt-on acquisitions and (iv) optimization of other liabilities.” • Consistent with our rigorous capital allocation strategy, we have just approved the investment of US$ 1.1 billion in the Salobo III copper project, a high return investment. Vale will receive a bonus ranging from approximately US$ 600 to 700 million from Wheaton Precious Metals, after achieving certain production targets. We have also approved a sustaining investment of US$ 428 million in the Gelado project, which will recover approximately 10 Mtpy of pellet feed with 64.3% Fe content, 2.0% silica and 1.65% alumina from tailings dams in the Carajás Complex, reducing opex (no trucks, no transportation distances and no grinding) and future capex (lower production rates and less replacement of equipment at the existing Carajás mine). Gelado shows the flexibility of our resource base, where even former waste is superior in quality to industry standards. Salobo III and Gelado will start up in 1H22 and 2H21, respectively. • Despite the US$ 4/t drop in iron ore prices, Ferrous Minerals EBITDA increased US$ 197 million when compared to 3Q17, totaling US$ 3.960 billion in 3Q18, showing strong volumes and premiums along with lower C1 cash costs. Mr. Peter Poppinga, Executive Officer for Ferrous Minerals and Coal commented, “Aligned with the consolidation of our differentiation strategy, the quality premium on Vale’s realized price improved for the third quarter in a row, achieving a record of US$ 11/t in 3Q18. The increase of over 7% vs. 2Q18 reflects our value over volume strategy, our margin optimization approach and our strong pricing position in the spot market, attesting to the intrinsic value of our premium products. Additionally, the demand for products with low contaminants, such as alumina and phosphorous, increased and contributed to higher market premiums.” • On August 27th, 2018, Metal Bulletin launched a new index, the MB 62% Fe low alumina, which is based on our blended product, Brazilian Blend Fines (BRBF). During 3Q18 the MB 62% Fe low alumina traded with a premium of US$ 5.9/t over the 62% index. The recently launched index better captures the intrinsic value of Vale’s BRBF. • 9M18 pellets EBITDA was US$ 2.4 billion, representing 19% of Vale’s total EBITDA and is on track to achieve more than US$ 3 billion in 2018. • As anticipated in 2Q18, our iron ore C1 cash cost decreased US$ 2.3/t totaling US$ 12.4/t in 3Q18, reflecting S11D’s ramp-up, higher productivity, dilution of fixed costs on higher volumes and exchange rate variation. • We continued to show strong competitiveness and our iron ore and pellets EBITDA breakeven in 3Q18 reduced even further and reached our lowest level ever of US$ 27.4/t in 4

3Q18, despite the inflationary pressures of bunker prices and spot freight rates. • Base Metals EBITDA was US$ 528 million in 3Q18, a decrease of US$ 250 million when compared to 2Q18, with about 65% of the decrease related to the exogenous factor of lower prices of nickel, copper and cobalt, and 35% mainly associated with Sudbury’s annual scheduled maintenance shutdown and its effects on lower by-product volumes and higher costs. Mr. Eduardo Bartolomeo, Executive Officer for Base Metals commented, “3Q18 results represented a tipping point for the Base Metals business. We are undergoing an important restructuring process led by our new management team with the focus on optimizing our operations, stabilizing our cost structure and reviewing mine plans. We are creating the basis for the nickel business to generate strong cash flows in any price scenario, while keeping the optionality to capture the upside of emerging demand for nickel in electric vehicles.” • Base Metals EBITDA in 9M18 was US$ 1.950 billion, significantly higher than the US$ 1.441 billion registered in 9M17. • The price of our nickel products was US$ 14,092/t in 3Q18, US$ 826/t higher than the average LME, representing an aggregate nickel price realization of 6.2% above LME prices, the highest percentage above the benchmark in the last 10 years.

Market overview IRON ORE Iron ore 62% Fe reference price averaged US$ 66.7/dmt in 3Q18, a decrease of 6% YoY, however it represents an increase of 2% from 2Q18 as steel production continues to respond to firm steel demand ahead of the winter season in the northern hemisphere. In China, the combination of steel capacity restrictions and healthy demand enabled steel mills to enjoy a solid margin. The increase in environmental awareness and controls is leading steel mills to optimize steel output whilst decreasing CO2 emissions. As a result, the market has recognized that higher Fe grade ores offer a substantial advantage and this can be seen through the premium captured by 65% Fe in the market and the resulting US$ 27/dmt in 3Q18. Vale is well positioned as a major supplier of sinter fines combining high Fe and low alumina, and also as a major supplier of pellets. COAL In 3Q18, seaborne coking coal prices decreased to US$ 188.6/t from US$ 190.2/t in the previous quarter, influenced by import restrictions in China and seasonally weaker demand from India due to monsoons. This has slowly improved in September due to restocking demand, logistics constrains and supply tightness. In the thermal coal market, 3Q18 Richards Bay FOB edged up to US$ 101.6/t, from US$ 100.3/t in the previous quarter. The quarter started very strong with prices reaching a 6 ½ year high during July at US$ 109.2/t. This price hike in July was driven by strong demand in Asia, increased coal-fired power generation in Europe and supply tightness from Colombia and USA. But the same has been downplayed from August and was impacted by weaker demand from India due to the monsoon, and arbitrage from Australian coals owing to weaker demand from China over import restrictions. NICKEL LME nickel prices declined during 3Q18 to an average of US$13,266/t, vs. US$ 14,476/t, in 2Q18. Total exchange inventories (LME and SHFE) continued to decline closing at 245 kt, at the end of 3Q18, down 165 kt since the end of 2017. Global stainless-steel production increased 2.4% in 3Q18 relative to 3Q17, while sales of EVs worldwide grew 48% during the same period. Demand for nickel in other applications continues to be positive. Supply decreased approximately 0.8% in 3Q18 relative to 3Q17, Class II (NPI) material increased (+5.6%) and Class I material declined (-8.3%) in the same period. Our near-term outlook for nickel remains cautious as current inventories will act as a buffer to price recovery. Meanwhile, macroeconomic factors such as the ongoing trade dispute between major powers introduce volatility to the base metals price complex, nickel included. Our long-term outlook for nickel continues to be positive. Nickel in electric vehicle batteries will become an increasingly important source of demand growth particularly as battery chemistry 6

favors higher nickel content due to lower cost and higher energy density. Capital is starting to flow back into the industry given the recovery in price. However, the timing of investments may increase the lag and widen future deficits given continued demand growth. COPPER LME copper price averaged US$ 6,105/t in 3Q18, a decrease of 11% from 2Q18 (US$ 6,872/t) impacted by concerns about the trade war. Copper inventories on all exchanges, LME, SHFE and COMEX, decreased by 294 kt in 3Q18 vs. 2Q18. Global demand increased approximately 1.8% in 3Q18 vs. 3Q17. In China, demand increased 3.2% in the same period and was driven primarily by increased infrastructure investment. On the supply side, global refined copper production increased nearly 1% in 3Q18 vs. 3Q17. More labor negotiations were concluded this quarter, reducing the potential for supply disruption for the year given that these settlements create precedent for the upcoming negotiations. Vale’s near-term outlook for copper shifted to a more positive tone, as the market is expected to remain essentially balanced for the year while maintaining a potential for deficit in 2019. The long-term outlook for copper is positive. Copper demand is expected to grow, partially driven by EVs and renewable energy as well as infrastructure investments, while future supply growth is challenged given declining ore grades and the need for greenfield investment. COBALT Cobalt price averaged US$ 65,724/t in 3Q18 a decrease of 25% vs. 2Q18, mainly due to the strong supply growth in the DRC and the continued drive to reduce cobalt use in EV batteries. Cobalt is one of the key metals, besides nickel, to produce the highest energy density batteries for use in electric vehicles. The cobalt market needs to grow significantly to feed into battery demand – but unlike other metals, cobalt is predominantly a by-product of nickel and copper mines. This means that it does not have the flexibility to respond to demand pressures as readily as other metals. Moreover, much of the cobalt comes from the DRC, which introduces ethical sourcing issues as well as reliance on operations in an unpredictable jurisdiction. Our near-term outlook for cobalt is mixed. Although demand for cobalt is increasing, supply is expected to increase as well with the start-up of major cobalt production in the DRC. Over the long term, although we see demand well supported by the battery market, chemistry developments are shifting to nickel-rich materials that bring lower cost and higher density. On the supply side, given the need to grow in nickel we see the nickel industry increase its contribution of cobalt units into the market, minimizing concerns about the future supply of cobalt for the electric vehicle battery market. 7

Adjusted EBITDA Adjusted EBITDA was US$ 4.374 billion in 3Q18, 12.1% higher than 2Q18 mainly as a result of (i) the strong operational performance of the Ferrous Minerals segment that reached an iron ore fines sales record of 83.5 Mt, representing a positive net effect of US$ 372 million on sales and COGS; (ii) the higher price realization (US$ 284 million) due to the increase in the share of premium products2 on total sales (79% in 3Q18 vs. 77% in 2Q18) together with the increase in the contributions of quality and average premium to the realized price of iron ore fines (US$ 8.6/t in 3Q18 vs US$ 7.1/t in 2Q18); and (iii) the positive impact on COGS (US$ 121 million) of BRL depreciation against USD. The above-mentioned US$ 777 million effect was partially offset by Base Metals’ lower volumes and prices (US$ 254 million).

Underlying earnings Following another strong operational performance, underlying earnings in 3Q18 were US$ 2.056 billion, remaining practically in line with 2Q18, with higher EBITDA being offset mainly by higher income tax in 3Q18. Income tax increased in 3Q18 mainly as a result of the positive impact on tax of shareholder remuneration declared as interest on equity in 2Q18. Underlying earnings exclude the non-cash impacts from net income such as: (i) the effect of the depreciation of BRL on USD denominated debt (US$ 765 million3); (ii) the impairment and other results on non-current assets of US$ 172 million. All the adjustments resulted in income tax of US$ 334 million in the underlying earnings. As a consequence of the non-cash impacts, net income was US$ 1.408 billion in 3Q18 vs. US$ 76 million in 2Q18.

Non-cash effects, such as the impact of the BRL depreciation, represented 60% of the net financial loss in 3Q18. Net financial results totaled a loss of US$ 1.263 billion mainly due to the BRL depreciation (3.8%) against the USD from BRL 3.8558/ USD as of June 30th, 2018 to BRL 4.0039/ USD as of September 30th, 2018. 3 Includes currency and interest rate swaps. 10 Others2210(52) Underlying earnings2,0562,0942,090 Foreign exchange and swaps7652,333(747) Impairment and other results in associates and joint ventures2041126 Items excluded from basic earnings US$ million3Q182Q183Q17

Equity income from affiliated companies Equity income from affiliated companies showed a gain of US$ 32 million in 3Q18. The main contributors to equity income were the leased pelletizing companies in Tubarão (US$ 76 million), CSI (US$ 24 million), VLI (US$ 21 million) and MRS (US$ 12 million), which was partly offset by losses from CSP (US$ 119 million). CSP losses were mainly due to the non-cash impact of the BRL depreciation on its USD denominated debt. Shareholders’ remuneration Vale considers its share buy-back program one of the best investments for its excess cash following the strong cash performance, the accelerated deleveraging profile and the positive outlook for its operational and financial performance. As such, Vale has executed 48.9% in 3Q18 of its US$ 1 billion share buy-back, purchasing 36.8 million shares at an average price of US$ 13.274 as of September 30th, 2018. According to Vale’s shareholder remuneration policy, the 1H18 result translated into a shareholder remuneration of R$ 7.694 billion that was equivalent to US$ 2.054 billion considering the exchange rate of July 24th, 2018. As a result of the BRL depreciation against the USD5, shareholder remuneration paid on September 20th, 2018 amounted to US$ 1.876 billion. The 3Q18 result yields a minimum shareholder remuneration of US$ 1.142 billion, which will be further increased by applying the threshold of 30% over adjusted EBITDA less sustaining investments to 4Q18 results, for payment in March 2019. 4 Net of brokerage fee. 5 The dividend of USD 0.3952 per share was translated into BRL at the exchange rate of BRL/USD 3.7459 on July 24th, 2018 but was effectively paid on September 20th, 2018 at the prevailing exchange rate of BRL/USD 4.0997. 11

CAPEX Capital expenditures totaled US$ 692 million in 3Q18 with US$ 123 million in project execution and US$ 569 million in sustaining capital. As a result of Vale’s more rigorous capital allocation approach, a new governance process was established in the implementation of sustaining projects, which led to a reengineering of some projects included in the 2018 budget. Consequently, the new governance concentration of disbursements in 4Q18, which together with the usual disbursements translates into a very high expenditure in the last quarter. will lead to a seasonality of Project Execution and Sustaining by business area Ferrous Minerals 437 63.2 462 65.5 551 63.8 Base Metals 223 32.2 208 29.5 289 33.5 Others - - - - 1 0.1 Project execution Investment in project execution totaled US$ 123 million in 3Q18, a decrease of US$ 82 million when compared to 2Q18, in line with Vale’s budget and reflecting that CLN S11D, its main capital project under development, is approaching its completion. In October 2018, Vale’s Board of Directors approved the investment of US$ 1.1 billion in the Salobo III copper project, a brownfield expansion increasing processing throughput capacity. The project encompasses a third concentrator line, and it will use Salobo’s existing infrastructure. Salobo III will produce an average copper volume of approximately 50 ktpy in the first 5 years, 42 ktpy in the first 10 years and 33 ktpy throughout the life of mine. As Salobo III will anticipate copper and gold production from the original mine plan, the life of mine will go until 2052 instead of 2067. Start-up is scheduled for 1H22 with a ramp-up of 15 months. Vale will receive a bonus ranging from approximately US$ 600 million to US$ 700 million from Wheaton Precious Metals after achieving certain production targets, as part of the previously negotiated terms of the goldstream transaction.

disbursements, the above-mentioned new governance process and higher investments in Ferrous Minerals and in VBME. In September 2018, Vale’s Board of Directors approved the Gelado project in the Northern System, for a total of US$ 428 million. The project encompasses the recovery of approximately 10 Mtpy of iron ore fines from the Gelado tailings dam up to 2031, in order to feed the recently restarted São Luís pellet plant. The tailings have an average of 64.3% Fe content, 2.0% of silica and 1.65% of alumina. The economics of the project are robust as it will (i) allow 9.7 Mtpy of iron ore production with zero transportation distance and no use of trucks, therefore reducing opex and (ii) reduce the mining rate at the existing Carajás mine, avoiding sustaining capital on the replacement of trucks. It also depicts the flexibility of Vale’s resource base – where even former waste is better than the industry’s standard product. In 3Q18, the Digital Transformation program continued its evolution, Vale’s Executive Board approved its extension into the Base Metals operations, in Canada. An additional US$ 116 million of a multiyear sustaining capex will encompass the implementation of 15 suites of projects for Sudbury operations. The main suites of projects that started to be developed are: (i) integrated planning and scheduling; (ii) cooling system; (iii) advanced insight center; and, (iv) tagging and tracking (Radio-Frequency IDentification RFID). The objective of the program in Sudbury is to unlock capacity for additional feed (~10%) over the first 3 years, aligned with the premium portfolio and the flexibility that Vale is enhancing in its operations. The Digital Transformation program encompasses more than 120 projects throughout the Ferrous Minerals and Base Metals segments totaling US$ 467 million approved up to 3Q18 to be spent by 2023. The Ferrous Minerals and Base Metals business segments accounted for 55% and 39%, respectively, of total sustaining capex in 3Q18, remaining in line with 2Q18. Sustaining capex in the Base Metals business segment was mainly for: (i) operational improvements (US$ 146 million); (ii) enhancements in the current standards of health and safety, social and environmental protection (US$ 64 million); and (iii) maintenance improvements and expansion of tailings dams (US$ 6 million). Sustaining capital for the Ferrous Minerals business segment included, among others: (i) enhancements and replacements in operations (US$ 219 million); (ii) improvements in the current standards of health and safety, social and environmental protection (US$ 44 million); and (iii) maintenance, improvement and expansion of tailings dams (US$ 31 million). Maintenance of railways and ports in Brazil and Malaysia accounted for US$ 76 million. 14

Education: promoting reading habits and access to books in 40 municipalities, benefiting more than 60,000 people, providing more than 30,000 books since 2012 and 21 reading locations in 2017. • In order to obtain effective results, Fundação Vale understands that development only becomes sustainable when there is an alignment between companies, the state and civil society. In this regard, Fundação Vale fosters a network amongst its suppliers and clients to integrate and leverage voluntary corporate social responsibility investments, and uses voluntary social investments for the implementation and strengthening of public policies. Portfolio Management In 3Q18, Vale concluded the sale of its 50% interest in the Eagle Downs hard coking coal project in Queensland, Australia, to a subsidiary of China BaoWu Steel Group Corporation Limited (Baosteel) for US$ 117 million in cash8, aligned with Vale’s strategy to simplify its asset portfolio and divest non-core assets. 8 Out of which US$ 90 million were a cash inflow in 3Q18 and US$ 27 million will be paid once operational preconditions are met. 16

Free cash flow Free cash flow was US$ 3.113 billion in 3Q18. The strong cash generation in the quarter enabled both continuity in the deleveraging of the company towards the US$ 10 billion net debt target and the return to investors of US$ 2.4 billion through interest on capital, dividends and share buyback. Free Cash Flow 3Q18 US$ million 17

Debt indicators Vale has continued to trim its net debt and practically achieved the US$ 10 billion net debt target, lowering it to US$ 10.704 billion as of September 30th, 2018, decreasing by US$ 815 million from June 30th, 2018 and by US$ 10.362 billion from September 30th, 2017, reaching the lowest net debt level since 3Q09. Leverage measured by net debt to LTM9 adjusted EBITDA remained at 0.7x, the lowest level since 1Q12. The debt decrease was supported by strong cash generation and was achieved despite the payment of shareholder remuneration of US$ 1.9 billion and the share buyback program10 of US$ 489 million, which occurred in 3Q18. Gross debt amounted to US$ 16.810 billion as of September 30th, 2018, decreasing by US$ 1.096 billion from June 30th, 2018 and by US$ 8.980 billion from September 30th, 2017. The decrease in gross debt compared to the end of last quarter was mainly due to net debt repayments11 of US$ 1.206 billion in 3Q18. Average debt maturity increased to 9.1 years on September 30th, 2018, against 8.9 years on June 30th, 2018. Average cost of debt, after currency and interest rate swaps, increased slightly to 5.09% per annum on September 30th, 2018 from 4.96% per annum on June 30th, 2018.

Ferrous Minerals ADJUSTED EBITDA Adjusted EBITDA of the Ferrous Minerals business segment was US$ 3.960 billion in 3Q18, US$ 732 million higher than in 2Q18, mainly due to higher sales volumes, lower C1 cash cost and better average premium, reflecting: (i) marketing efforts to position Vale’s premium product portfolio; (ii) the flexibility of the operations; (iii) the active supply chain management; (iv) the share of premium products in total sales; and (v) stronger market premiums. The successful ramp-up of S11D and Tubarão pellet plants I and II led to quarterly records in production and sales volumes, increasing the share of premium products, which achieved the record of 79% of total sales, and decreasing the level of contaminants. Therefore, Vale’s portfolio is benefiting from the structural “flight to quality” trend with rising market premiums. Iron ore fines and pellets quality premiums broke the barrier of US$ 10/t for the second consecutive quarter, totaling US$ 11.0/t in 3Q18 and resulting in a gain of US$ 158 million vs. 2Q18. The strong operational performance was also translated into unit costs reductions beyond the positive effect of exchange rate variation, with total savings amounting to US$ 166 million.

FERROUS MINERALS ADJUSTED EBITDA MARGIN12 Adjusted EBITDA per ton for Ferrous Minerals, excluding Manganese and Ferroalloys, was US$ 40.0/t in 3Q18, an increase of US$ 3.2/t when compared to the US$ 36.8/t recorded in 2Q18. After normalizing the impacts of 62% iron ore market reference prices, bunker oil prices and exchange rate on the previous quarters, 3Q18 adjusted EBITDA per ton maintained its progressive growth trend and posted a new record, being US$ 1.9/t higher than the second-best quarter in Vale’s history (2Q18). Normalized EBITDA/t – Ferrous Minerals business segment Iron ore fines (excluding Pellets and ROM) ADJUSTED EBITDA13 Adjusted EBITDA of iron ore fines was US$ 3.083 billion in 3Q18, 31.2% higher than 2Q18, mainly due to higher volumes (US$ 352 million), higher premiums (US$ 135 million), higher market reference prices (US$ 117 million) and exchange rate variations (US$ 77 million). SALES REVENUES AND VOLUME Net sales revenues of iron ore fines, excluding pellets and run of mine (ROM), increased to US$ 5.594 billion in 3Q18 vs. US$ 4.570 billion in 2Q18, as a result of higher sales volumes (US$ 705 million) and higher sales prices (US$ 319 million). 12 Excluding Manganese and Ferroalloys. 13 Considers the new allocation criteria for general and administrative expenses as described in the box “Managerial Allocation Changes” of the 1Q18 Earnings Release. 22

Sales volumes of iron ore fines achieved a quarterly record of 83.5 Mt in 3Q18, despite the increase in offshore stocks to support the ongoing blending activities. CFR sales of iron ore fines totaled 61.0 Mt in 3Q18, representing 73% of all iron ore fines sales volumes in 3Q18, 4.4 p.p. higher than in 2Q18. The sales mix has been consistently improving mainly as a result of S11D and Tubarão I and II pellet plants ramp-ups. The share of premium products (pellets, Carajás, Brazilian Blend Fines – BRBF, pellet feed and Sinter Feed Low Alumina - SFLA) increased to 79% in 3Q18, contributing to the US$ 1.5/t increase of Vale’s average premium in the realized iron ore fines CFR/FOB wmt price in 3Q18 vs. 2Q18, which has been continuously improving to reach US$ 8.6/t in 3Q18 vs. US$ 7.1/t in 2Q18 and US$ 5.6/t in 3Q17.

REALIZED PRICES Pricing system breakdown - % Price realization – iron ore fines Vale’s CFR dmt reference price for iron ore fines (ex-ROM) was US$ 76.6/t, US$ 9.9/t higher than the market reference price for 62% Fe content, mainly as a result of higher quality and premiums (US$ 8.6/t). Vale’s realized price increased 6.9% (US$ 4.3/t) and totaled US$ 67.0/t, mainly as a result of the above-mentioned higher premiums. The ‘Premiums/Discounts and commercial conditions’ totaled US$ 6.6/t in 3Q18, achieving the highest level ever and increasing by US$ 1.6/t from the US$ 5.0/t recorded in 2Q18. The record 24 The percentage of sales recorded under the provisional pricing system in relation to total sales in 3Q18 was in line with 2Q18, after having decreased in the previous quarters. This new level reflects Vale’s reduced time to market, following the increased number of distribution centers offshore, and therefore being closer to the end customer. The reduction of the share of provisional pricing system sales also improves the predictability of Vale’s results, as it decreases the price adjustments.

was a result of marketing efforts to position Vale’s premium product portfolio and the dynamic supply chain management maximizing margins. Additionally, Vale’s realized premiums were also supported by stronger market premiums.

Base Metals ADJUSTED EBITDA Base Metals adjusted EBITDA was US$ 528 million in 3Q18 vs. US$ 778 million in 2Q18, with about 65% of the US$ 250 million decrease related to the exogenous factor of lower prices for nickel, copper and cobalt (US$ 162 million). The remainder was mainly associated with Sudbury’s annual scheduled maintenance shutdown and its effects on lower by-product volumes, leading to lower volumes (US$ 86 million) and higher costs22 (US$ 33 million), mostly from one-off effects of the above-mentioned maintenance shutdown. Despite lower LME prices, the average nickel realized price was US$ 14,092/t, US$ 826/t higher than the average LME nickel price of US$ 13,266/t in 3Q18, an aggregate nickel price realization 6.2% above LME prices, the highest percentage above the benchmark in the last 10 years, and in line with the strategy of exploring the potential of its premium nickel products. Base Metals EBITDA in 9M18 was US$ 1.950 billion, significantly higher than the US$ 1.441 billion registered in 9M17. The EBITDA increase comes even with the one-off adaptations of Canadian flowsheet in 3Q18 and the resumption of Coleman mine in 2Q18. Looking forward, the Base Metals business will improve its performance based on the operational stabilization plan of its new management team along with the tailwind of EV demand for battery-suitable nickel as a catalyst in the medium to long-term.

Details of nickel operations’ adjusted EBITDA by operation are as follows: • The North Atlantic operations EBITDA was US$ 148 million, decreasing by US$ 245 million vs. 2Q18 mainly due to lower nickel and by-product volumes (US$ 77 million), higher costs (US$ 76 million) and lower nickel, copper and cobalt realized prices (US$ 73 million). Unit cash costs increased mostly due to lower copper, and other by-products volumes as nickel volumes decreased in the quarter with Sudbury’s maintenance shutdown and Thompson’s transition to a mine-mill operation. Also, there were the effects of lower dilution of fixed costs, as nickel volumes decreased in the quarter, and lower by-product prices, in line with lower LME benchmark prices. • PTVI’s EBITDA was US$ 70 million, increasing by US$ 4 million when compared to 2Q18, due to slightly higher nickel price realization (US$ 3 million) related to the timing of deliveries in the quarter. Unit cash costs were in line with 2Q18. • VNC's EBITDA was negative US$ 42 million, decreasing by US$ 43 million when compared to 2Q18, mainly as a result of lower nickel and cobalt realized prices (US$ 33 million) and higher costs23 (US$ 11 million). Unit cash costs increased with lower cobalt prices affecting by-product credits and also due to lower ore deliveries from the mine and refinery limitations. • Onça Puma’s EBITDA was US$ 29 million, increasing by US$ 4 million when compared to 2Q18. Unit cash costs were in line with 2Q18 as favourable exchange rate variations offset a slight increase in costs related to energy and supplies. 23 Costs net of volume effect. 30

EBITDA breakeven – nickel operations24 SALES REVENUES AND VOLUMES Nickel sales revenues were US$ 807 million in 3Q18, decreasing US$ 104 million vs. 2Q18 as a result of lower sales volumes (US$ 64 million) and lower realized prices (US$ 40 million). Sales volumes of nickel were 57 kt in 3Q18, 5 kt lower than in 2Q18. Nickel sales volumes were lower than in 2Q18 in line with lower production in the quarter, partially offset by drawdown of finished inventory in 3Q18. Copper by-product from nickel operations generated sales revenues of US$ 96 million in 3Q18, decreasing US$ 80 million vs. 2Q18 as a result of lower sales volumes (US$ 50 million), mainly related to lower copper by-product from the North Atlantic operations, and lower copper realized prices (US$ 30 million) following the decrease in the LME benchmark. Sales volumes of copper by-product totaled 21 kt in 3Q18, 9 kt lower than in 2Q18. Sales volumes were lower than in 2Q18 reflecting the annual scheduled maintenance in Sudbury and the strategic decision to decrease mine production at Voisey’s Bay to extend the mine lifespan to match the Voisey’s Bay Mine Extension (VBME) underground development schedule. Cobalt by-product sales revenues totaled US$ 65 million in 3Q18, decreasing US$ 29 million vs. 2Q18 mainly as a result of lower cobalt prices (US$ 18 million). Sales volumes of cobalt by-product amounted to 1,120 t in 3Q18, 152 t lower than in 2Q18.

In 3Q18, 56% of our production was high-quality Class I. Considering Class II products that can be used in the production of batteries, 82% of Vale’s current quarterly production has an upside with the advent of EVs. The proportion of Class I within the nickel product mix decreased temporarily in 3Q18 as a result of the one-off lower production from Sudbury and Thompson. 32 PGMs ('000 oz)9013885 Intermediates4411 ‘000 metric tons3Q182Q183Q17 Nickel576271

Class I products, 32 kt, 56% of nickel sales in 3Q18 Class I products are sourced from 100% of North Atlantic operations and 46% of PTVI operations. Part of the Class I nickel products is being sold at premiums for the specialties/high-quality markets but part of it is sold to stainless-steel Class II markets, with lower premiums. As demand for specialty products and batteries for EVs increases, a larger portion of our high-quality Class I nickel products will be sold to Class I markets, capturing a larger share of premiums among its products. In line with the strategy to increase awareness of the quality of Vale’s new Class I products, in September Vale welcomed more than 80 significant customers to attend a workshop in Long Harbour. The event was an opportunity for customers to learn about Vale’s business, its processes and to see, firsthand, how Vale’s new plating rounds were made as well as its benefits. Class II Battery-suitable, Class II and Intermediates, 25 kt, 44% of nickel sales in 3Q18 Class II Battery-suitable products offer an upside for use as feed into the battery supply chain for EV batteries. Although technically any nickel can be upgraded to the purity level required by the EV batteries market, the products comprising the Class II Battery-suitable nickel are those which offer economic feasibility and cost-efficient solutions to be used in that market. Also, the different products included in this category offer different levels of potential and readiness for 33

utilization in EVs. The Class II Battery-suitable products are sourced from 100% of VNC operations and 35% of PTVI operations. It is economically challenging to use Class II products such as ferro-nickel in electric vehicle battery applications, mainly due to impurities, operational costs and capital costs associated with the conversion process. Vale’s Class II products are sourced from 100% of Onça Puma operations. Intermediate products are sourced from 19% of PTVI production. These products do not represent finished nickel production and are generally sold at a discount given that they still need to be processed before being sold to end customers.

Details of copper operations’ adjusted EBITDA by operation are as follows: • Sossego’s EBITDA was US$ 52 million, decreasing by US$ 9 million vs. 2Q18, mainly as a result of lower copper realized prices (US$ 24 million) that were partially offset by positive exchange rate variations (US$ 7 million) and higher volumes (US$ 6 million). Unit cash costs decreased mainly due to dilution of costs on higher by-product volumes along with the positive effect of exchange rate variations. • Salobo’s EBITDA was US$ 216 million, in line with 2Q18. Unit cash costs decreased to US$ 351/t, reaching close to negative cost levels, mainly due to higher by-product credits, the impact of higher volumes on fixed cost dilution and the positive effect of exchange rate variations. EBITDA breakeven – copper operations26 The realized price to be used against the EBITDA breakeven should be the copper realized price before discounts (US$ 5,590/t), given that TC/RCs and other discounts are already part of the EBITDA breakeven build-up. SALES REVENUES AND VOLUMES Copper sales revenues were US$ 356 million in 3Q18, decreasing US$ 38 million vs. 2Q18 as a result of lower realized prices (US$ 75 million) which were partially offset by higher copper volumes (US$ 37 million). Copper sales volumes were 71 kt in 3Q18, 6 kt higher than in 2Q18, in line with the increase in production over the quarter. By-products revenues were US$ 143 million in 3Q18, increasing US$ 6 million vs. 2Q18 as a result of higher volumes (US$ 20 million) which were partially offset by lower by-product prices (US$ 13 million). Sales volumes of gold by-product were 114,000 oz in 3Q18, 15,000 oz higher than in 2Q18 and sales volumes of silver by-product were 211,000 oz in 3Q18, 48,000 oz lower than in 2Q18. 26 Considering only the cash effect of US$ 400/oz that Wheaton Precious Metals pays for 75% of Salobo’s gold by-product, copper operations EBITDA breakeven would increase to US$ 2,659/t 36

Vale’s copper products are sold on a provisional pricing basis during the quarter with final prices determined in a future period, generally one to four months forward27. The realized copper price differed from the average LME price in 3Q18 due to the following factors: • Current period price adjustments: mark-to-market of invoices still open in the quarter based on the copper price forward curve28 at the end of the quarter (-US$ 47/t); • Prior period price adjustment: variance between the price used in final invoices (and in the mark-to-market of invoices from previous quarters still open at the end of the quarter) and the provisional prices used for sales in previous quarters (-US$ 468/t); and, • TC/RCs, penalties, premiums and discounts for intermediate products (-US$ 602/t). Price realization – copper operations 27 On September 30th, 2018, Vale’s copper operations had provisionally priced copper sales totaling 57,485 tons valued at an LME forward price of US$ 6,201/t, subject to final pricing over the following months. 28 Includes a small number of final invoices that were provisionally priced and settled within the quarter. 37 Gold as by-product ('000 oz)11499104 ‘000 metric tons3Q182Q183Q17 Total500531593 Gold as by-product140133134 US$ million3Q182Q183Q17

(b) Adjusted EBITDA EBITDA defines profit or loss before interest, tax, depreciation and amortization. Vale uses the term adjusted EBITDA to reflect exclusion of gains and/or losses on sale of assets, non-recurring expenses and the inclusion of dividends received from non-consolidated affiliates. However, our adjusted EBITDA is not the measure defined as EBITDA under IFRS, and may possibly not be comparable with indicators with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for operational profit or as a better measure of liquidity than operational cash flow, which are calculated in accordance with IFRS. Vale provides its adjusted EBITDA to give additional information about its capacity to pay debt, carry out investments and cover working capital needs. The following table shows the reconciliation between adjusted EBITDA and operational cash flow, in accordance with its statement of changes in financial position: 46 Adjusted EBIT3,5253,0413,184 Other operational expenses(12)(82)(151) Research and development(87)(92)(91) COGS(5,756)(5,377)(5,412) US$ million3Q182Q183Q17 %3Q182Q183Q17
