EBITDA reached US$909 million in 3Q18, increasing 5% from 3Q17 and 4% from 2Q18

3Q18 HIGHLIGHTS:

Braskem – Consolidated:

4 EBITDA in 3Q18 was US$909 million, up 4% from 2Q18, due to sales recovery in Brazil following the end of the truck drivers' strike and by the higher sales volume in the United States and Mexico, that were affected by lower production volume in 2Q18. These effects offset lower spreads for resins in Brazil, for PP in Europe and for PE in North America. Compared to 3Q17, EBITDA in U.S. dollars grew 5%, due to the positive effect of Brazilian real depreciation of costs and expenses pegged to the currency.

4 Net income came at R$1,344 million, growing 146% and 68% compared to 2Q18 and 3Q17, respectively.

4 Strong cash generation in this period supported the reduction of financial leverage measured by the ratio of net debt to EBITDA ¹ in U.S. dollar from 1.90x in 2Q18 to 1.81x this quarter.

4 In September, the Company partially redeemed US$200 million in perpetual bonds, in line with its strategy to reduce the cost of debt.

4 Free cash flow in the quarter was R$1.5 billion.

4 The recordable and lost-time injury frequency rate per million hours worked was 1.25.

4 As per the Material Fact notice dated September 24, Braskem was informed by Odebrecht, its controlling shareholder, that the shareholders' agreement dated February 8, 2010 was amended to include the preferred shares held by Petrobras in the tag-along rights provision set forth in Clause 7.12 of the agreement.

4 Consistent with best practices of corporate governance, two new independent directors were elected to the Board of Directors. As a result, eight of the 11 directors are now independent.

4 In November, Braskem announced its positioning on Circular Economy and defined 9 key global initiatives: (i) partnerships with Clients to develop products and applications that facilitate the recycling and reuse of plastic packaging; (ii) investments in new resins derived from renewable resources; (iii) developing and supporting new technologies for recycling; (iv) recycling and conscientious consumerism programs; (v) studies of life cycle assessments and the environmental impact of plastics; (vi) support for measuring and reporting recycling rates for plastic packaging; (vii) partnerships for understanding, preventing and solving the problem of marine debris ; and (viii) encouraging science-based policies to understand the origin and prevent the disposal of debris in the oceans, especially plastic.

1 Excludes the Project Finance in Mexico.

PETROCHEMICAL INDUSTRY 3Q18:

4 Spreads of key chemicals ² produced by Braskem, US$404/ton, were up 3% and 12% from 2Q18 and 3Q17 respectively, mainly due to higher butadiene prices, driven by strong demand from construction, automotive and electronics sectors.

4 Average international spread of the polyolefins ³ produced by Braskem in Brazil, US$537/ton, was down 18% and 21% from 2Q18 and 3Q17 respectively, due to increased supply of PE in the United States, with the startup of the new ethane-based capacity, and to lower resin demand in Asia due to the trade war between the United States and China.

4 International spread for Vinyls ⁴ , US$621/ton, was down 5% and 14% from 2Q18 and 3Q17 respectively, reflecting higher naphtha price, and lower caustic soda price due to lower demand, after one of the world’s leading alumina producers cut production in the quarter.

4 PP spread in United States ⁵ , US$683/ton, increased 2% and 17% compared to 2Q18 and 3Q17, supported by strong demand, especially from automotive and household appliance sectors, and by the unscheduled shutdowns of PP plants.

4 PP spread in Europe ⁶ , US$318/ton, was down 18% and 42% from 2Q18 and 3Q17, due to higher propylene prices, and by weaker demand for resins.

4 PE spread in North America ⁷ , US$874/ton, was down 20% and 8% from 2Q18 and 3Q17, due to higher ethane prices driven by strong demand from recently started crackers in the United States, combined with the tightness of midstream infrastructure (pipelines and fractionation plants).

2 Difference between the prices of key chemicals (15% ethylene, 10% propylene, 35% BTX, 10% butadiene, 5% cumene and 25% fuels, based on the capacity mix of Braskem’s industrial units in Brazil) and the price of naphtha – Source: IHS.

3 Difference between the price of PE and PP based on the capacity mix of Braskem’s industrial units in Brazil and the price of naphtha – Source: IHS. IHS.

4 Corresponds to: PVC Price - (Naphtha ARA) - [ (Brent Oil Price/1.725)*1.75] + (0.685 x Caustic Soda Price)

^⁵ Difference between the U.S. polypropylene price and the U.S. propylene price.

6 Difference between the Europe polypropylene price and the Europe propylene price.

^⁷ Difference between the U.S. polyethylene price and the U.S. ethane price.

1. BRAZIL

4 In 3Q18, the crackers operated at an average capacity utilization rate of 95%, 5 p.p. higher than in 2Q18, due to the normalization of production after the end of logistics constraints arising from the truck drivers' strike. Compared to 3Q17, the average capacity utilization rate increased 3 p.p., as that quarter was adversely impacted by the scheduled shutdown of the cracker in Rio de Janeiro.

4 Resin demand in the Brazilian market (PE, PP and PVC) was 1.4 million tons in 3Q18, up 9% from 2Q18, with the elimination of the logistics constraints arising from the truck drivers' strike and also influenced by seasonality. Compared to 3Q17, resin demand increased by 3%. In the year to date, demand for resins grew 3% in relation to 9M17, driven by stronger economic activity, especially in the packaging, consumer goods, agribusiness and automotive industries.

4 Braskem resin sales amounted to 917 kton, increasing 12% from 2Q18 to outperform the overall market in this period. Compared to 3Q17, sales volume was stable. In 9M18, Braskem’s resin sales in Brazil grew 1% to 2,624 kton relative to 9M17.

4 In 3Q18, the Company exported 358 kton of resins, 12% higher than in 2Q18, due to higher product supply, and was 10% lower than in 3Q17.

4 In Brazil, sales of chemicals increased compared to 2Q18, influenced by the higher supply of products for sale due to the normalization of production.

4 Exports of chemicals grew compared to 2Q18, reflecting higher supply of products, led by exports of paraxylene to Asia, where prices reached record highs on strong demand for the product to make polyesters. Compared to 3Q17, exports of chemicals decreased 26%.

4 In 3Q18, COGS in Brazil was adversely affected by (i) higher ARA naphtha price reference due to higher crude oil prices driven by concerns regarding the possible impacts of sanctions imposed by the United States on Iran; (ii) the higher price of ethane in the United States, and (iii) the higher propane price in the United States, which was influenced by higher oil prices, low inventories in this period and the continued strong demand for the propane exports from the United States.

4 In 3Q18, the units in Brazil posted EBITDA of R$2,218 million, accounting for 64% of the Company’s consolidated EBITDA from all segments.

4 In early October, the petrochemical industry special regime (REIQ) was not passed into law, which kept the PIS/COFINS taxes levied on the acquisition of domestic and imported raw materials unchanged at 5.65%.

2. UNITED STATES AND EUROPE ⁸

4 In 3Q18, the capacity utilization rate was 87%, up 3 p.p. from 2Q18, reflecting lower downtimes caused by unscheduled shutdowns. Compared to 3Q17, the capacity utilization rate fell 7 p.p., due to (i) the scheduled Turnaround of the Wesseling Unit in Germany; (ii) logistics constraints on propylene shipments to the plants in Europe due to low river levels; and (iii) operating issues in the United States.

4 In the United States, PP demand contracted in relation to 2Q18 after the resin reached very high price levels. In Europe, the market contracted in line with the region’s economic performance.

4 In the quarter, PP sales amounted to 477 kton, down in relation to both 2Q18 and 3Q17, due to the lower supply of products for sale and the weaker market in Europe.

4 The increase in COGS compared to both 2Q18 and 3Q17 is explained by the higher propylene price, which accompanied the hike in crude oil prices in the period.

4 In 3Q18, the unit posted EBITDA of R$716 million (US$182 million), accounting for 20% of the Company’s consolidated EBITDA from all segments.

8 The segment’s results are formed by six industrial units in the United States and two in Europe, with aggregate production capacity of 2,195 kta, with 1,570 kta in the United States and 625 kta in Europe.

4 Construction of the new PP plant in the United States reached 32.8% completion, with US$341 million in investments already made.

3. MEXICO (Braskem Idesa) ⁹

4 In 3Q18, the PE plants operated at a capacity utilization rate of 78%, 6 p.p. higher than in 2Q18, when capacity utilization was adversely affected by the scheduled shutdown in May. Compared to 3Q17, the capacity utilization declined 9 p.p. due to the lower supply of ethane.

4 In the quarter, PE sales in the Mexican market amounted to 136 kton, up 1% from 2Q18 and down 11% from 3Q17, representing 67% of the total sales.

4 Exports were stable in relation to 2Q17 and down in comparison with 3Q17, reflecting the strategy to prioritize sales to domestic markets in Mexico.

4 The increase in COGS compared to 2Q18 is due to the higher ethane prices in the United States, as explained previously.

4 The other operating income in 3Q18 included income of US$16.5 million related to the deliver-or-pay established in the ethane supply agreement.

4 In 3Q18, the Mexico complex posted EBITDA of R$559 million (R$141 million) to account for 16% of the Company’s consolidated EBITDA.

9 The segment comprises an ethane-based cracker, two high-density polyethylene (HDPE) plants and one low-density polyethylene (LDPE) plant with combined PE production capacity of 1,050 kta. This unit includes the results of Braskem Idesa SAPI and of the other subsidiaries of Braskem S.A. in Mexico.

4. CONSOLIDATED RESULTS ¹⁰

EBITDA

NET FINANCIAL RESULT

10 Braskem’s consolidated result corresponds to the sum of the results in Brazil, United States & Europe and Mexico, less eliminations from the revenues and costs from the transfers of products among these regions.

Financial expenses: impacted by the effects from local-currency depreciation on interest expenses, as well as by costs associated with the prepayment of more expensive debt.

Financial income: increase in relation to 2Q18 due to the higher interest income on financial investments in Brazilian real.

Net exchange variation: impacted by exchange variation (net exposure of the financial result not designated for hedge accounting) and by the effects from the appreciation in the Mexican peso against the U.S. dollar on the outstanding balance of the loan of Braskem Idesa in the amount of US$2,083 million on September 30, 2018.

Net exchange variations also were affected by the expenses with the transition to export hedge accounting, which is recorded under shareholders’ equity, in the amounts of R$252 million at Braskem and R$61 million at Braskem Idesa.

5. LIQUIDITY AND CAPITAL RESOURCES

On September 30, 2018, the average debt term was approximately 15 years, while the average weighted cost of the Company’s debt was equivalent to exchange variation + 5.63%.

Braskem’s liquidity position of US$1,525 million is sufficient to cover the payment of all obligations maturing over the next 30 months. Considering the international revolving credit facility in the amount of US$1 billion and undrawn, the coverage is 51 months.

Supported by strong cash generation, Braskem partially redeemed US$200 million of its 7.375% perpetual bonds at par value in September, as a strategy to reduce the debt interest expenses.

Risk-rating agencies:

Braskem maintained investment grade ratings at Standard & Poor's (BBB-) and Fitch Ratings (BBB-); above Brazil’s sovereign risk, with stable outlook at the three main agencies. The reports are available on the Investor Relations website ( http://www.braskem-ri.com.br/ ).

6. INVESTMENTS AND VALUE CREATION ¹¹

11 Considers operating investment, maintenance shutdowns and acquisitions of spare parts.

4 New PP plant in the United States

At the end of 3Q18, Braskem already had invested US$341 million and construction had reached 32.8% of completion, as follows:

o Engineering Detailing: 96.5% completed.

o Equipment and Material Acquisitions: 86.5% completed.

o Construction: 24.3% completed.

7. FREE CASH FLOW ¹²

In 3Q18, Braskem recorded free cash flow of R$1,543 million, down 54% from 2Q18, due primarily to the larger balance of accounts receivable and inventories due to the higher petrochemicals prices, and the depreciation of the Brazilian real against the U.S. dollar, with these factors partially offset by the positive impact from the larger balance of trade payables due to higher feedstock prices and by the weaker Brazilian real. Compared to 3Q17, cash generation increased 45%, due to the positive effects from Brazilian real depreciation on the Company’s operating cash flow. In the year to date, free cash flow was R$6,630 million.

8. SUSTAINABLE DEVELOPMENT

4 Positioning Circular Economy

In November, Braskem announced its global positioning for the Circular Economy. Braskem recognizes that adequate management of the disposal of post-consumer plastic waste is a growing global concern. For society to leverage the benefits that plastics offer, it is essential that the material be recovered properly to avoid causing harm to the environment. Plastics must be used responsibly, reused, recycled or recovered. Accordingly, the Company defined eight key initiatives:

i. Building partnerships to develop new products and applications to improve efficiency and promote recycling and reuse (circular design), especially for single-use packaging;

12 Note that the cash flow analysis above does not consider the reclassification of “cash and cash equivalents” to “financial investments” related to financial investments in Brazilian federal government bonds (Brazilian floating-rate (SELIC) government bond - LFT) and floating-rate bonds (LFs) issued by financial institutions, whose original maturities exceed three months, with immediate liquidity and expected realization in the short term, in accordance with Note 4 to the Quarterly Financial Statements as of June 30, 2018. In the cash flow presented, this is recorded as “financial investments” (includes LFTs and LFs), with the following effects from reclassifications: (i) reduction in the balance of financial investments of R$167 million in 1Q17; (ii) reduction in the balance of financial investments of R$42 million in 4Q17; (iii) increase in the balance of financial investments of R$100 million in 1Q18; (iv) increase in the balance of financial investments of R$46 million in 2Q18; and (v) increase in the balance of financial investments of R$9 million in 3Q18.

ii. Investing in the development of new renewable products to support the circular economy at the beginning of the value chain;

iii. Supporting and developing new technologies, business models and systems for collecting, picking, recycling and recovering materials, considering the best balance of economic, social and environmental impacts;

iv. Engaging consumers in recycling and recovery programs, especially through educational programs on responsible consumerism to further knowledge on the value of plastic waste to the economy;

v. Supporting and using life cycle assessment tools to select the most sustainable option, considering the economic, social and environmental impacts of plastic;

vi. Supporting the measurement and communication of recycling and recovery indicators for plastic packaging materials;

vii. Building partnerships to understand, prevent and solve the problem of debris in the oceans, with support from the scientific community and researchers;

viii. Supporting comprehensive science-based policies to understand the origins of and prevent debris in the oceans and to improve the management of solid waste, especially plastics.

4 Sustainable Development

Braskem continues to focus on strengthening its contribution to sustainable development, mitigating risks and seeking shared value creation. In this context, the highlights in 3Q18 were:

§ Braskem and the United Nations: Braskem was recognized by the UN for its engagement with the commitments to sustainable development of the UN Global Compact and was considered a Global Compact LEAD company, joining a select group of only 34 companies. The Company's case study on water management was presented during a meeting organized by the Brazil Network of the Global Compact in New York, in side events to the UN General Assembly.

§ Human Rights: based on two studies conducted in partnership and, with the sponsorship of Braskem, the Childhood Foundation, a Brazilian organization of the World Childhood Foundation, held a regional meeting in the region near the Camaçari Complex, in which it presented a project to combat and prevent sexual violence against children and teens. The project should be launched in January 2019.

§ Diversity: Braskem signed, in partnership with another 31 large corporations, a letter sent to the presidential candidates in the 2018 elections to request that they recognize the importance of diversity and inclusion in the workplace. The letter is part of the initiative of the NGOs Grupo Dignidade and Aliança Nacional LGBTI and of the organization Out & Equal Workplace Advocates.

§ Plastics Recycling: Braskem forged a long-term partnership with the U.S. football team Philadelphia Eagles. A new plastics recycling program will be implemented in the team’s stadium, along with an online educational platform for 30 public schools in the region. The partnership emphasizes the Company’s commitment to environmental and community development.

§ Green PE: Braskem partnered with Peel Plastics Products, specialized in flexible packaging in the United States, to develop a new packaging for the household fertilizers products sold by Scotts Canada, a world leader in products for gardening and hydroponic agriculture.

§ Sustainable Agribusiness: Braskem participated in the 20 ^th edition of the ETHOS 360 Conference in São Paulo on the sustainable agribusiness and plastic demand panel, seeking to promote dialogue on growing demand for plastics applications and more sustainable agribusiness techniques.

4 Recognition by the Media

Consolidated Balance Sheet – Liabilities

* On the reporting date of the quarterly financial statements, Braskem was in unremedied default with part of the non-financial obligations contracts. As a result, the entire balance of non-current liabilities, in the amount of R$10,136,271, was reclassified to current liabilities, in accordance with CPC 26 and its corresponding accounting standard IAS 1 (Presentation of Financial Statements). In accordance with the aforementioned accounting standards, reclassification is required in situations in which the breach of certain contractual obligations entitles creditors to request from Braskem Idesa the prepayment of obligations in the short term. In this context, note that none of the creditors requested or expressed any intention of requesting said prepayment of obligations. Braskem Idesa has been settling its debt service obligations in accordance with their original maturity schedule. Furthermore, Braskem Idesa continues to negotiate approval of such breaches with its creditors in order to reclassify the entire amount reclassified from current liabilities back to non-current liabilities.

** Includes the exchange variation of financial liabilities designated as hedge accounting.
