ITEM 3. KEY INFORMATION

Selected Financial and Other Information

The following selected information should be read in conjunction with “Presentation of Financial and Other Information,” “Item 5. Operating and Financial Review and Prospects” and our audited consolidated financial statements and the related notes thereto, which are included in this annual report.

The selected financial data as of December 31, 2015 and 2014 and for the three years ended December 31, 2015 have been derived from our audited consolidated financial statements, prepared in accordance with IFRS, and included in this annual report.

Our audited consolidated financial statements as of December 31, 2015 and 2014 and for the three years ended December 31, 2015 have been adjusted for the effects of the restatement more fully described in the “Explanatory Note” of this annual report and in note 2.4 to our audited consolidated financial statements.

As a result of the Investigation described in the “Explanatory Note” on this annual report, we identified several errors in our previously issued financial statements as of December 31, 2015 and 2014 and for the three years ended December 31, 2015, which have been restated.

The selected financial data as of December 31, 2013, 2012 and 2011 and for the years ended December 31, 2012 and 2011 have been derived from Braskem’s accounting records and reflect the restatement of improperly classified expenses from selling and distribution expense to other expense and to correct errors in the calculation of taxes payables.

We have included information with respect to the dividends and/or interest attributable to shareholders’ equity paid to holders of our common shares and preferred shares since January 1, 2011 in reais and in U.S. dollars translated from reais at the commercial market selling rate in effect as of the payment date under the caption “Item 8. Financial Information—Dividends and Dividend Policy—Payment of Dividends.” We prepare individual financial statements in accordance with Brazilian GAAP for certain purposes, including for the calculation of dividends.

Exchange Rates

The Brazilian foreign exchange system allows the purchase and sale of foreign currency and the international transfer of reais by any person or legal entity, regardless of the amount, subject to certain regulatory procedures.

Since 1999, the Central Bank has allowed the U.S. dollar- real exchange rate to float freely, and, since then, the U.S. dollar- real exchange rate has fluctuated considerably.

In the past, the Central Bank has intervened occasionally to control unstable movements in foreign exchange rates. We cannot predict whether the Central Bank or the Brazilian government will continue to permit the real to float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. The real may depreciate or appreciate against the U.S. dollar substantially. Furthermore, Brazilian law provides that, whenever there is a serious imbalance in Brazil’s balance of payments or there are serious reasons to foresee a serious imbalance, temporary restrictions may be imposed on remittances of foreign capital abroad. We cannot assure you that such measures will not be taken by the Brazilian government in the future. See “—Risk Factors—Risks Relating to Brazil—Brazilian government exchange control policies could increase the cost of servicing our foreign currency-denominated debt, adversely affect our ability to make payments under our foreign currency-denominated debt obligations and impair our liquidity” and “—Risk Factors—Risks Relating to Our Class A Preferred Shares and the ADSs— If holders of the ADSs exchange them for class A preferred shares, they may risk temporarily losing, or being limited in, the ability to remit foreign currency abroad and certain Brazilian tax advantages.”

The following table shows the selling rate for U.S. dollars for the periods and dates indicated. The information in the “Average” column represents the average of the exchange rates on the last day of each month during the periods presented.

Risk Factors

Risks Relating to Our Company and the Petrochemical Industry

The cyclical nature of the petrochemical industry may reduce our net sales revenue and gross margin.

The petrochemical industry, including the markets in which we compete, is cyclical and sensitive to changes in global supply and demand. This cyclicality may reduce our net sales revenue and gross margin, including as follows:

Historically, the international petrochemical markets have experienced alternating periods of limited supply, which have caused prices and profit margins to increase, followed by expansion of production capacity, which has resulted in oversupply and reduced prices and profit margins. Prices in the Brazilian petrochemical industry follow the global petrochemical industry, and we establish the prices for the products we sell in Brazil with reference to international market prices. Therefore, our net sales revenue and gross margin are increasingly linked to global industry conditions that we cannot control.

Our revenue from customers is significant, and the credit risks associated with certain of these customers could adversely affect our operating results.

We engage in a number of transactions where counterparty credit risk is a relevant factor, including transactions with customers and those businesses we work with to provide services, among others. These risks are dependent upon market conditions and also the real and perceived viability of the counterparty. The failure or perceived weakness of any of our counterparties has the potential to expose us to risk of loss in certain situations. Our revenue from our customers is significant, and the credit risks associated with certain of these customers could adversely affect our operating results. Certain contracts and arrangements that we enter into with counterparties may provide us with indemnification clauses to protect us from financial loss. To the extent the credit quality of these customers deteriorates or these customers seek bankruptcy protection, our ability to collect our receivables, and ultimately our operating results, may be adversely affected.

The Company’s reported results may be adversely affected by increases in reserves for uncollectible accounts receivable.

The Company has a large balance of accounts receivable and has established a reserve for the portion of such accounts receivable that the company estimates will not be collected because of the company’s customers’ non-payment.

If the business viability of certain of the Company’s customers deteriorates or the company’s credit policies are ineffective in reducing the company’s exposures to credit risk, additional increases in reserves for uncollectible accounts may be necessary, which could have a material adverse effect on our cash flows and results of operations. We record an allowance for doubtful accounts in an amount considered sufficient to cover estimated losses on the realization of our trade accounts receivable, taking into account our loss experience and the aging of our accounts receivable.

As of December 31, 2015, our total trade accounts receivable was R$3,103.5 million and the provision for doubtful accounts was R$328.0 million. Significant changes in our historical loss experience on accounts receivable which are not apparent through our aging analysis could require significant changes to our provisions for doubtful accounts.

Global macroeconomic factors have had, and may continue to have, adverse effects on the margins that we realize on our products.

Our results of operations may be materially affected by adverse conditions in the financial markets and depressed economic conditions generally. Economic downturns in geographic areas in which we sell our products may substantially reduce demand for our products and result in decreased sales volumes. Recessionary environments adversely affect our business because demand for our products is reduced.

Slowed growth in emerging economies resulted in decreased growth in the global economy, which increase is estimated at 3.1% in 2015, according to the International Monetary Fund. In 2015, Brazil’s GDP contracted 3.8%, as compared to growth of 0.1% in 2014 and 3.0% in 2013. In 2015, apparent consumption for thermoplastic resins in Brazil declined by 7.6%.

In the U.S. and Europe, GDP grew by 2.4% and 1.5%, respectively in 2015 compared to growth of 2.4% and 0.9% in 2014. Mexico’s GDP grew by 2.5% in 2015 compared to 2.3% in 2014.

Our ability to export to other countries is a function of the level of economic growth in these countries and other economic conditions, including prevailing inflation and interest rates. In addition, disruptions in the global balance between supply and demand may impair our ability to export our products in response to a decline in domestic demand for these products. Prolonged volatility in economic activity in our key export markets could continue to reduce demand for some of our products and lead to increased margin pressure by importers into Brazil, which would adversely affect our results of operations.

We face competition from producers of polyethylene, polypropylene, PVC and other petrochemical products.

We face competition in Brazil from foreign producers of polyethylene, polypropylene, PVC and other petrochemical products. Our U.S. operations face competition in the United States from other U.S. producers of polypropylene. Our German operations face competition in Europe and the other export markets that it serves from European and other foreign producers of polypropylene. We expect that our Mexico operations will face competition from U.S. producers of polyethylene producers.

We generally set the prices for our second generation products sold in Brazil with reference to the prices charged for these products by foreign producers in international markets. We generally set the prices for our second generation products exported from Brazil based on international spot market prices. We set the prices for polypropylene sold in the United States and Europe based on regional market pricing. The price for polyethylene in Mexico will be based on prices for the polymer in the U.S Gulf Coast region.

As a result of the announced commissioning of new ethylene capacity, particularly in the United States, in the Middle East and in China, coupled with the increased competitiveness of gas-based ethylene producers in United States as a result of their relatively lower raw material costs, we anticipate that we may experience increasing competition from other producers of second generation products in the markets in which we sell these products. In addition, the appreciation of the real against the U.S. dollar may increase the competitiveness of prices of imported products in reais, which may increase the competition in Brazil from other producers of second generation products. Some of our foreign competitors are substantially larger and have greater financial, manufacturing, technological and/ or marketing resources than our company.

Higher raw materials costs would increase our cost of goods sold and services rendered and may reduce our gross margin and negatively affect our overall financial performance.

Naphtha, a crude oil derivative, is the principal raw material used by our Basic Petrochemicals Unit and, indirectly, in our other business units. Naphtha accounted, directly and indirectly, for approximately 44.5% of our consolidated cost of sales and services rendered in 2015.

We purchase a portion of the naphtha and natural gas used by our Basic Petrochemicals Unit from Petróleo Brasileiro S.A.—Petrobras, or Petrobras, at prices based on the Amsterdam-Rotterdam-Antwerp and Mont Belvieu market prices of naphtha and natural gas liquids.

Table of Contents

The price of naphtha that we purchase from international suppliers is also linked to the Amsterdam-Rotterdam-Antwerp reference. The Amsterdam-Rotterdam-Antwerp market price of naphtha fluctuates primarily based on changes in the U.S. dollar-based price of Brent crude oil on the Intercontinental Exchange based in London. Oil markets may face strong volatility due to: (1) the impact of new non-OPEC production, primarily from the United States; (2) OPEC’s decisions with regards to their production quotas; and (3) political uncertainties in the Middle East and North Africa. In 2015, the price of the front-month contract on Brent crude oil decreased by 40.6% from a high of US$64.32 per barrel in May 2015 to a low of US$38.21 per barrel in December 2015. Volatility of the price of naphtha and the upward trend in the price of oil and naphtha have effects on the price competitiveness of our naphtha-based crackers.

The average Amsterdam-Rotterdam-Antwerp market price of naphtha in U.S. dollars declined by 44.7% to US$462 per ton in 2015 from US$836 per ton in 2014 and US$903 per ton in 2013, with its highest price of reaching US$551 per ton in May 2015 and its lowest price reaching US$387 per ton in December 2015.

The Mont Belvieu prices of ethane have had similar volatility, with the average market price of ethane decreasing to US$139 per ton in 2015 from US$228 per ton in 2014 and US$190 per ton in 2013, with its highest price reaching US$165 per ton in January 2015 and its lowest price reaching US$108 per ton in November 2015.

The price of naphtha and natural gas liquids in U.S. dollars has been, and may continue to be, volatile. In addition, the fluctuations of the U.S. dollar in the future may effectively increase our naphtha or natural gas costs in reais . Any increase in naphtha or natural gas costs would reduce our gross margin and negatively affect our overall financial performance to the extent we are unable to pass on these increased costs to our customers and could result in reduced sales volumes of our products.

The production of natural gas liquids, particularly in North America, may reduce the global prices of polyethylene, which would reduce our gross margin and negatively affect our overall financial performance.

In recent years, the use of ethane as a feedstock for the production of ethylene has increased as a result of its increasing availability and the divergence between the cost of natural gas and oil (from which naphtha is derived and the pricing of condensate is based). Production of natural gas liquids have increased, particularly in North America, as the technology to extract gas from shale has improved. In order to improve their global competitiveness, most U.S. ethylene producers with the raw material flexibility to use ethane as a feedstock have converted to the use of light feedstocks.

As a result of the increase in the production of natural gas liquids in North America, (1) ethane has returned as a low-cost alternative to oil-based products and (2) additional gas production has resulted in an increasingly competitive ethane price. North American polyethylene producers have benefited from the low-cost position of natural gas prices, and the resulting increased competitiveness of North American polyethylene producers could decrease the global and domestic price of polyethylene, which would reduce our gross margin and negatively affect our overall financial performance.

We do not hedge against changes in the price of our principal raw materials, so we are exposed to fluctuations in the price of these primary raw materials.

Currently, we do not hedge our feedstock’s price exposure. We believe the petrochemical industry has a natural hedge, mainly due to the observed historical correlation between its feedstock (most notably, naphtha) and its final products (Polyethylene, Polypropylene, PVC, etc.). Historically, fluctuations in naphtha’s price were followed by variations in the same direction in petrochemical products of the first and second generation. This eventual hedge solely in naphtha’s price would break this natural protection, probably making our results more volatile. However, considering Braskem’s ongoing process of feedstock diversification, with ethane, propane and propylene representing a more significant portion of our variable costs, the natural hedge described above tends to be impaired. This occurs because ethane and propane have significantly lower correlation to the price of our final products, when compared to naphtha and propylene. If this scenario materializes, we may not immediately be able to pass on all of the corresponding increases in our feedstocks costs, which would likely reduce our gross margin and net income.

We depend on Petrobras to supply us with a substantial portion of our naphtha, ethane and propane requirements.

Petrobras is the only Brazilian supplier of naphtha and has historically supplied approximately 70% of the naphtha consumed by our Basic Petrochemicals Unit. Petrobras produces most of the naphtha it sells to us and imports naphtha to serve the gasoline pool and to sell to us. Petrobras currently is also the only Brazilian supplier of ethane and propane and has historically supplied the ethane and propane consumed at our petrochemical complex located in Duque de Caxias in the State of Rio de Janeiro, or the Rio de Janeiro Complex.

Our production volume and net sales revenue would likely decrease and our overall financial performance would likely be negatively affected in the event of the following:

On December 23, 2015, we finalized and executed an agreement for the supply of naphtha with Petrobras at a price indexed to the Amsterdam-Rotterdam-Antwerp naphtha quotation. This agreement replaced the previous amendments and will be valid for a five-year period as of December 23, 2015 and establishes that both parties will have commercial renegotiation rights as of the third year should certain market conditions change.

In addition, although regulatory changes have ended Petrobras’ monopoly in the Brazilian naphtha market and have allowed us to import naphtha, any restrictions imposed on the importation of naphtha into Brazil could increase our production costs.

We depend on propylene supplied by third parties in the US and in Europe

Our reliance on third-party suppliers poses significant risks to our operating results, business and prospects. We rely upon third-party suppliers for our plants, to supply us with propylene. We acquire propylene for our polypropylene plants in the Unites States under a variety of long-term supply agreements and through the spot market. As of December 31, 2015, we had long-term supply agreements with multiple suppliers. In Germany, we acquire propylene for our polypropylene plants under long-term supply agreements that provide for the supply of approximately 95% of the propylene requirements of these plants.

We are subject to substantial risks because of our reliance on these and other limited or sole source suppliers, including the following risks:

Table of Contents

Delays in the availability of propylene or propylene of acceptable quality, or our inability to obtain such acceptable propylene in the quantities we need or at all, may adversely affected our revenue and operating results.

Our Polyolefins Unit and Vinyls Unit depend on our basic petrochemicals plants to supply them with their ethylene and propylene requirements.

Our Basic Petrochemicals Unit is the only supplier of ethylene to our Vinyls Unit, the only supplier of ethylene to the polyethylene plants of our Polyolefins Unit and the principal supplier of propylene to the polypropylene plants of our Polyolefins Unit. Because the cost of storing and transporting ethylene is substantial and there is inadequate infrastructure in Brazil to permit the importing of large quantities of ethylene and propylene, our polyolefins plants in Brazil and our Vinyls Unit are highly dependent on the supply of these products by our basic petrochemicals plants. Consequently, our production volumes of, and net sales revenue from, polyolefins and vinyls products would decrease, and our overall financial performance would be negatively affected, in the event of the following:

We depend on Petrobras for a significant portion of the propylene that we use in Brazil to produce polypropylene and we will depend on Pemex Gas for all of the ethane that we will use in Mexico to produce ethylene .

During 2015, approximately 36% of the propylene used by our Polyolefins Unit was supplied by Petrobras. During 2015, our Etileno Project was not yet operational; however, once operational, all of the ethane used by the project will be supplied by Pemex.

As a result of limited infrastructure in Brazil to allow the importation of propylene in large quantities and substantial costs associated with the storage and transportation of the product, we are highly dependent on the propylene supplied by Petrobras. Thus, production volumes and net sales revenue from polypropylene products would decrease and adversely affect our overall financial performance in the event of the following:

Braskem Idesa has entered into a long-term supply contract to purchase ethane from Pemex Transformación Industrial (successor of Pemex Gas y Petroquímica Básica), or Pemex TRI, a state-owned Mexican company, under competitive commercial conditions. Any termination by Pemex TRI of this supply contract could have a material adverse effect on our overall financial performance. The provisions for early termination by Pemex TRI include but are not limited to (i) material breach of our obligations or failure to cure any breach of the agreement or assignment and (ii) continuous occurrence of a force majeure event or emergency shutdown.

Any downgrade in the ratings of our company or our debt securities would likely result in increased interest and other financial expenses related to our borrowings and debt securities and could reduce our liquidity.

Standard & Poor’s Ratings Group, a division of McGraw Hill, Inc., or S&P, Moody’s Investors Service, Inc., or Moody’s, and Fitch Ratings Ltd., or Fitch, maintain ratings of our company and our debt securities. Currently, Standard & Poor’s and Fitch maintain ratings of our company on global and national basis. Moody’s only maintains ratings of our company on a global basis. Standard & Poor’s maintains a rating for our company of “BBB- (negative)” on a global basis and a rating for our company of “brAAA (negative)” on a national basis; Fitch maintains a rating for our company of “BBB- (negative)” on a global basis and a rating for our company of “AA+ (negative)” on a national basis; and Moody’s maintains a rating for our company of “Ba1 (negative)” on a global basis. Any decision by these agencies to downgrade the ratings of our company or of our debt securities in the future would likely result in increased interest and other financial expenses relating to our borrowings and debt securities and the inclusion of financial covenants in the instruments governing new indebtedness, and could significantly reduce our ability to obtain such financing on satisfactory terms or in amounts required by us and our liquidity and would require us to post cash collateral pursuant to our obligations.”

Some of our shareholders may have the ability to determine the outcome of corporate actions or decisions, which could affect the holders of our class A preferred shares and the ADSs.

Odebrecht S.A., or Odebrecht, directly or through its wholly-owned subsidiary Odebrecht Serviços e Participações S.A., or OSP, owns 38.3% of our outstanding share capital, including 50.1% of our voting share capital and Petrobras holds 36.1% of our outstanding share capital, including 47.0% of our voting share capital. Designees of Odebrecht constitute a majority of the members of our board of directors. Under a shareholders’ agreement to which OSP and Petrobras are parties, which we refer to as the Petrobras Shareholders’ Agreement, we may only undertake certain actions after Odebrecht and Petrobras have reached a consensus with respect to those actions. However, Odebrecht will have the sole power to approve the business plan of our company, through the board of directors, as described under “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders—Shareholders’ Agreements.” As a result, Odebrecht has the ability to determine the outcome of most corporate actions or decisions requiring the approval of our shareholders or our board of directors — in certain instances, with the consent of Petrobras — which could affect the holders of our class A preferred shares and the American Depositary Shares, or ADSs.

We may face conflicts of interest in transactions with related parties.

We maintain trade accounts receivable and current and long-term payables with some of our affiliates and other related parties, including Petrobras, which is our domestic supplier of naphtha and other raw materials such as propylene, ethane, propane and light refinery hydrocarbons. These accounts receivable and accounts payable balances result mainly from purchases and sales of goods, which are at prices and on terms equivalent to the average terms and prices of transactions that we enter into with third parties. These and other transactions between us and our affiliates could result in conflicting interests between our company and these shareholders.

We may make significant acquisitions which, if not successfully integrated with our company, may adversely affect our operating results.

We may make significant acquisitions in the future. Acquisitions involve risks, including the following:

10

Table of Contents

If we are unable to integrate or manage acquired businesses successfully, we may not realize anticipated cost savings, revenue growth and levels of integration, which may result in reduced profitability or operating losses.

We may face unforeseen challenges in the operation of Project Ethylene XXI which could result in this project failing to provide expected benefits to our company.

During the first half of 2016, we expect to conclude the construction phase of an olefins complex, or the Mexico Complex, located in the Mexican state of Veracruz. For more information about this project, which we refer to as Project Ethylene XXI, see “Item 5. Operating and Financial Review and Prospects—Capital Expenditures—Joint Venture Projects—Project Ethylene XXI.”

Braskem Idesa S.A.P.I., or Braskem Idesa, our joint venture with Grupo Idesa, S.A. de C.V., or Idesa, one of Mexico’s leading petrochemical groups, to develop Project Ethylene XXI, required significant capital expenditure. Our ability to achieve the strategic objectives of this project will depend largely on its successful operation. Factors that could affect the operation of this project include:

We cannot assure you that this project will provide the expected benefits to our company and that the actual cost or time required to complete the implementation of this project will not substantially exceed our current estimates. Any significant interruption could hinder or prevent the implementation of our business plan as originally conceived, and result in revenues and net income below expected.

Future adjustments in tariffs on imports that compete with our products could cause us to lower our prices.

We currently benefit from tariffs imposed by the Brazilian government on imports that allow us to charge prices for our polyolefin and vinyl products in the domestic market that include a factor based on the tariffs levied on comparable imports of those products. However, the Brazilian government has in the past used import and export tariffs to effect economic policies, with the consequence that tariffs can vary. For example, in September 2012, the Brazilian government increased import duties on 100 products related to various industries, including an increase on the import tariff for polyethylene. In October 2012, it increased the import tariff for polyethylene from 14% to 20% and in October 2013, it reduced the import tariff for polyethylene to the previous level of 14%. Future adjustments of tariffs could lead to increased competition from imports and cause us to lower our domestic prices, which would likely result in lower net sales revenue and could negatively affect our overall financial performance. Additionally, the products we export to the United States and Europe are subject to tariffs in the amount of 6.5% in each jurisdiction, subject to certain preferences. These tariffs generally favor our products produced locally and any future adjustments to these tariff structures could negatively impact our sales in these jurisdictions. Future trade agreements entered into by Brazil, the United States or the European Union could also lead to increased competition from imports and lower domestic prices.

Our business is subject to stringent environmental regulations, and the imposition of new regulations could require significant capital expenditures and increase our operating costs.

We, like other Brazilian petrochemical producers, are subject to stringent Brazilian federal, state and local environmental laws and regulations concerning human health, the handling and disposal of solid and hazardous wastes and discharges of pollutants into the air and water. Petrochemical producers are sometimes subject to unfavorable market perceptions as a result of the environmental impact of their business, which can have an adverse effect on their results of operations.

Table of Contents

Our operations in the United States, Germany and Mexico are subject to extensive U.S., German and Mexican federal, state and local laws, regulations, rules and ordinances relating to pollution, protection of the environment and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. U.S. environmental laws and regulations may impose liability on us for the conduct of third parties, or for actions that complied with applicable requirements when taken, regardless of negligence or fault. Of particular significance to us are (1) regulatory programs to be established to implement air quality standards under the National Ambient Air Quality Standards for ozone and fine particles promulgated by the U.S. Environmental Protection Agency, or the EPA, and (2) various legislative and regulatory measures in the United States which are under review, discussion or implementation to address greenhouse gas emissions. In Mexico, we adhere to the comprehensive responsibility program promoted by ANIQ, which is based on the Responsible Care standard used in the United States and Canada.

Costs and capital expenditures relating to environmental, health or safety matters are subject to evolving regulatory requirements and will depend on the timing of the promulgation and enforcement of specific standards which impose the requirements. Moreover, changes in environmental regulations could inhibit or interrupt our operations, or require modifications to our facilities. Accordingly, environmental, health or safety regulatory matters may result in significant unanticipated costs or liabilities.

We manufacture products that are subject to the risk of fire, explosions and other hazards.

Our operations are subject to hazards, such as fires, explosions and other accidents, associated with the manufacture of petrochemicals and the storage and transportation of feedstock and petrochemical products. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment and environmental damage. A sufficiently large accident at one of our plants or storage facilities could force us to suspend our operations temporarily and result in significant remediation costs and lost net sales revenue.

Although we maintain insurance coverage for losses due to fire damage and for losses of income resulting from shutdowns due to fire, explosion or electrical damage, those insurance proceeds may not be available on a timely basis and may be insufficient to cover all losses, which could have a material adverse effect on our financial performance.

Unfavorable outcomes in pending or future litigation may reduce our liquidity and negatively affect our financial performance and financial condition.

We are, and in the future may be, involved in numerous tax, civil and labor disputes, among others, involving monetary claims. If unfavorable decisions are rendered in one or more of these lawsuits, we could be required to pay substantial amounts. For some of these lawsuits, we have not established any provision on our balance sheet or have established provisions only for part of the amounts in question, based on our judgments as to the likelihood of winning these lawsuits.

In July 2015, two putative class action lawsuits were filed against us and certain of our then-current and former officers and directors, or the Defendants, in the United States District Court for the Southern District of New York. The lawsuits were subsequently consolidated under the caption In re Braskem, S.A. Securities Litigation, No. 15-cv-5132. In November 2015, Boilermaker-Blacksmith National Pension Trust, or the Lead Plaintiff, filed a consolidated class action complaint, which asserted claims under Section 10(b) and Section 20(a) of the Exchange Act, on behalf of a putative class of purchasers of our American Depositary Receipt, or ADRs, from June 1, 2010 to March 11, 2015. In the operative complaint, the Lead Plaintiff alleges that the Defendants made misrepresentations or omissions that inflated the price of our stock in violation of U.S. securities laws. We filed a motion to dismiss on July 6, 2016. On March 31, 2017, the court ruled on the motion to dismiss, granting it in part and denying it in part. With respect to the remaining claims, the class action is now in the discovery stage. The parties are also currently engaged in settlement negotiations and have signed a proposed settlement agreement and submitted it to the U.S. court for preliminary approval on September 14, 2017. Under the terms of the proposed settlement, we would pay

12

Table of Contents

US$ 10 million to resolve all claims of a settlement class consisting of purchasers of our ADRs during the period of July 15, 2010 through March 11, 2015, that arise out of or relates to the subject matter of the class action, with the exception of any such claims belonging to purchasers who file, valid and timely, requests to opt out of the settlement class. We have made no admission of any wrongdoing or liability as part of the proposed settlement, and it is subject to a number of conditions, including court approval. Furthermore, we may be named as a defendant in other legal actions, and we may be required, in accordance with any applicable legal and regulatory limits, to indemnify directors, officers and employees that are defendants in this securities class action and any other related actions that may arise in the future. The litigation has required and may continue to require significant time and attention in the future. For more information about our legal proceedings, see “Item 8. Financial Information—Legal Proceedings.”

Labor unrest may materially and adversely affect our operations.

Labor unrest in our plants and facilities may have a material adverse effect on our financial condition or results of operations. For example, in August 2010, the unionized employees at our Neal, West Virginia plant went on strike. During the strike, the plant operated under the supervision of management until May 2011, when Braskem America entered into a new collective bargaining agreement. Although we believe that we maintain good relations with our employees, future labor actions, including strikes, could have a material adverse effect on our financial performance.

Natural disasters, severe weather and climate conditions could have a material adverse effect on our overall business.

Some of our facilities are located in places that could be affected by natural disasters, such as floods, earthquakes, hurricanes, tornados and other natural disasters, which could disrupt our operations or the operations of our customers and could damage or destroy infrastructure necessary to transport our products as part of the supply chain. Such events could require maintenance shutdowns, delay shipments of existing inventory or result in costly repairs, replacements or other costs, all of which could have a material adverse effect on our financial performance.

While Braskem’s energy risk policy dictates that it purchases energy in advance at fixed prices through long-term contracts, the majority of Brazilian power generation capacity is provided by hydroelectric generation facilities. If the amount of water available to energy producers becomes scarce due to drought or diversion for other uses, the cost of energy may increase. Such conditions could have a material adverse effect on our sales and margins.

We could be materially adversely affected by the impacts of the Global Settlement.

In the context of allegations of improper payments in connection with the so-called Operation Car Wash in Brazil, we engaged the Expert Firms to conduct the Investigation and report their findings. We have cooperated with governmental authorities in several jurisdictions, including the DoJ, the SEC, the MPF, and the OAG. On December 14, 2016, we entered into a leniency agreement with the MPF, or the Leniency Agreement, which was ratified by the competent Brazilian court on June 6, 2017. On December, 21, 2016, we filed a plea agreement in the United States District Court for the Eastern District of New York under which we agreed to plead guilty to a one-count criminal information charging our company with conspiracy to violate the anti-bribery provisions of the FCPA. On the same date, we consented to the entry of a final judgment in a civil action brought by the SEC based on civil violations of the anti-bribery, books and records and internal accounting controls provisions of the FCPA. The competent federal courts in the United States approved the DoJ and SEC resolutions on January 26, 2017 and February 28, 2017, respectively. In addition, on December 21, 2016, the OAG closed its investigation of these matters. We refer to these actions as the Global Settlement.

Under the Global Settlement, we agreed to pay to the governmental authorities in these jurisdictions an aggregate amount of approximately US$957 million (equivalent to approximately R$3.1 billion).

Of the total amount payable pursuant to the Global Settlement, we have already paid approximately R$1.3 billionas follows:

The aggregate amount of approximately R$1.8 billion outstanding pursuant to the Global Settlement will be paid in the following manner:

The Global Settlement may have a material adverse effect on our business, reputation, financial condition, financial instruments and operational results, as well as on the liquidity and price of our securities, including our class A preferred shares and ADSs. Furthermore, the negative publicity resulting from the Global Settlement, the facts made public through our plea agreement in the United States, and the facts that will be made public when the Leniency Agreement with the MPF is ultimately disclosed, could have a material adverse impact on our business, including reducing the demand for our products , our financial instruments and other effects that currently cannot be estimated or measured. In addition, other authorities with jurisdiction over our company may seek to impose additional monetary sanctions or fines or commence new investigations against us. Finally, as a result of the Global Settlement, we may be barred from entering into certain agreements with governmental authorities, and may be subject to increased operating costs in connection with our obligations to improve our governance and anti-corruption practices, including the cost of required external monitorship.

Under the terms of the Global Settlement, we are required to cooperate with these governmental authorities and improve our governance and anti-corruption compliance practices. We will also be subject to external monitorship for a period of three years, during which time the monitor will assess compliance with the Global Settlement, including the effectiveness of our internal controls, policies and procedures to reduce the risk of any anti-corruption violations. The monitorship period may be terminated early or extended for up to one year at the authorities’ discretion depending on our compliance with the Global Settlement. We have retained monitors pursuant to the provisions of the Global Settlement, and they have been approved by the relevant authorities. The monitors may recommend changes to our policies and procedures, which we must adopt unless they are unduly burdensome or otherwise inadvisable, in which case we may propose alternatives that the authorities may choose to accept. Operating under the oversight of the monitors will likely require the assumption of additional responsibilities by members of our management. We currently cannot estimate the costs that we are likely to incur in connection with compliance with the Global Settlement, including the implementation of the recommended changes, if any, to our policies and procedures as required by the monitors. However, the costs of the monitorship could be significant and could negatively impact our company by requiring the efforts of our management team, diverting attention from our ordinary business operations.

Compliance and Control Risks

We could be materially affected by violations of the U.S. Foreign Corrupt Practices Act, the Brazilian Anti-Corruption Law and similar anti-corruption laws.

We, our subsidiaries and our joint venture partners are subject to a number of anti-corruption laws, including Law No. 12,846/2013, or the Brazilian Anti-Corruption Law, which became effective on January 28, 2014, the FCPA and various other anti-corruption and anti-bribery laws of other jurisdictions.

The FCPA, the Brazilian Anti-Corruption Law and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. Violations of these laws may result in criminal or civil

sanctions, inability to do business with existing or future business partners, injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly engaging in certain types of businesses, the loss of business permits or other restrictions which could have a material adverse effect on our business, financial condition, results of operations or liquidity.

We are exposed to behaviors of our employees and non-employees that may be incompatible with our ethics and compliance standards, and failure to timely prevent, detect or remedy any such behavior and/or process vulnerabilities may have a material adverse effect on our results of operations and financial condition.

Our business, including our relationships with third parties, is guided by ethical principles. We have adopted a Policy on Compliance in Acting Ethically with Integrity and Transparency, and several internal policies designed to guide our management, employees and counterparties and reinforce our principles and rules for ethical behavior and professional conduct. We maintain an independent whistleblower channel (denominated “Ethics Line”) managed by a third party available for employees and non-employees (including third parties). Every whistleblower complaint is investigated and submitted for evaluation by our Ethics Committee.

We are subject to the risk that our employees, counterparties or any person doing business with us may engage in fraudulent activity, corruption or bribery, circumvent or override our internal controls and procedures or misappropriate or manipulate our assets for their personal or business advantage. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. We have in place a robust Compliance and Anti-Corruption Program being implemented through every area of our company, including several processes for identifying, monitoring and mitigating these risks, but such program may not be completely effective.

As a result of the Investigation, we determined that material weaknesses in our internal control over financial reporting as of December 31, 2015 existed. We identified material weaknesses related to (i) our control environment and anti-corruption compliance controls and programs designed to prevent and detect violations of the FCPA and other applicable anti-corruption laws, (ii) the review and approval of reconciliation and manual payments, and (iii) the review of the ledger accounts used to record accruals and payments of commissions. These material weaknesses were identified primarily because a number of deficiencies in controls and errors were detected during the Investigation.

We subsequently identified an additional material weakness related to (iv) the review and monitoring over in-transit inventory for naphtha imports processed by our subsidiary, Braskem Netherlands. This material weakness was identified during the financial statement audit performed for Braskem Netherlands.

A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

We are currently implementing several remediation efforts to improve our governance and compliance systems. See “Item 4. Information on the Company—Compliance.” However, such improvements may not be completely effective, and certain of our employees and non-employees may behave in a manner that is incompatible with our ethics and compliance standards. In addition, we may make accounting errors in our future financial reporting, and we cannot be certain that in the future additional material weaknesses in our internal control over financial reporting will not exist. Any failure—real or perceived—to follow our compliance principles or to comply with applicable governance or regulatory obligations could harm our reputation and image, limit our ability to obtain financing and otherwise have a material adverse effect on our results of operations and financial condition.

If we are unable to comply with the restrictions and covenants in the agreements governing our indebtedness, there could be a default under the terms of these agreements, which could result in an acceleration of payment of funds that we have borrowed and could affect our ability to make principal and interest payments on our debt obligations.

Any default under the agreements governing our indebtedness that is not cured or waived by the required lenders could result in the holders of any such indebtedness accelerating the payment of amounts outstanding, which could make us unable to pay principal and interest on those and other debt obligations. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal and interest on our indebtedness, or if we otherwise fail to comply with the various covenants in the agreements governing our indebtedness (including covenants in the project finance debt related to our Mexico Complex), we could be in default under the terms of such agreements. In the event of such default:

Although our Mexico Complex is fully operational and Braskem Idesa has satisfied and continues to satisfy its debt service requirements and all other payment obligations under its US$3,194 million senior secured Syndicated Facility on a timely basis, certain defaults have occurred and are continuing thereunder. These defaults give the creditors thereunder the right to vote to accelerate their debt under this facility and exercise their remedies in respect of the collateral for the facility, including the Mexico Complex and the outstanding shares of Braskem Idesa. Braskem Idesa has submitted requests for waiver of these defaults to and is currently negotiating such waiver with the intercreditor agent for this facility. However, there can be no assurance that the intercreditor agent and the lenders will agree to extend such waiver, or if they agree to extend such waiver, whether the waiver will include additional obligations with which Braskem Idesa would be required to comply.

We may in the future need to obtain waivers under our other indebtedness to avoid being in default. If we breach any covenants under any of our debt instruments and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under such agreements, the lenders could exercise their rights or remedies, as described above, and we could be forced into bankruptcy or liquidation.

Risks Relating to Brazil

Brazilian political and economic conditions, and the Brazilian government’s economic and other policies, may negatively affect demand for our products as well as our net sales revenue and overall financial performance.

The Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government and unstable economic cycles. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the course of Brazil’s economy. The Brazilian government’s actions to control inflation and implement other policies have at times involved wage and price controls, blocking access to bank accounts, imposing capital controls and limiting imports into Brazil.

Our results of operations and financial condition may be adversely affected by factors such as:

Brazilian markets have been experiencing heightened volatility due to the uncertainties derived from the ongoing Car Wash investigation, which is being conducted by the Office of the Brazilian Federal Prosecutor, and its impact on the Brazilian economy and political environment. Members of the Brazilian federal government and of the legislative branch, as well as senior officers of the state-owned oil company Petróleo Brasileiro S.A. – Petrobras, or Petrobras, have faced allegations of political corruption. These government officials and senior officers allegedly accepted bribes by means of kickbacks on contracts granted by Petrobras to several infrastructure, oil and gas and construction companies, including our controlling shareholder Odebrecht S.A. We cannot currently predict how the Car Wash investigation and any future decisions and actions by authorities in relation to our shareholders, may impact the Company. The profits of these kickbacks allegedly financed the political campaigns of political parties of the current federal government that were unaccounted for or not publicly disclosed, as well as served to personally enrich the recipients of the bribery scheme. As a result of the ongoing Car Wash investigation, a number of senior politicians, including congressman and officers of the major state-owned companies in Brazil resigned or have been arrested. Senior elected officials and other public officials in Brazil are being investigated for allegations of unethical and illegal conduct identified during the Car Wash investigation.

In addition, the Brazilian Congress opened impeachment proceedings against President Dilma Rousseff on December 2, 2015 for allegedly breaking budget laws as she increased economic stimulus during her re-election campaign last year. On April 17, 2016, the Brazilian Congress voted in favor of the admissibility of the impeachment proceedings and the Brazilian Senate is expected to vote on the impeachment on May 11, 2016. The impeachment proceedings have adversely affected and we expect that they will continue to adversely affect the Brazilian markets and trading prices of securities issued by Brazilian issuers. We cannot predict either the outcome of the impeachment proceedings or their effects on the Brazilian economy. Any developments in the impeachment proceedings could have a material adverse effect on us.

Table of Contents

The potential outcome of these investigations and proceedings is uncertain, but they have adversely affected and we expect that they will continue to adversely affect the Brazilian markets and trading prices of securities issued by Brazilian issuers. We cannot predict whether the allegations or proceedings will lead to further political and economic instability or whether new allegations against government officials or other companies in Brazil will arise in the future. In addition, we can neither predict the outcome of any such allegations and proceedings nor their effect on the Brazilian economy. The development of those unethical conduct cases could have a material adverse effect.

Future changes in industrial policy and related actions undertaken by the Brazilian government may negatively affect demand for our products as well as our net sales revenue and overall financial performance.

We currently benefit from certain industrial policies and related actions undertaken by the Brazilian government intended to strengthen the domestic economy and certain local industries. Some of these policies and actions have recently included reductions in payroll taxes for plastic manufacturers, a program to improve the competitiveness of Brazilian producers in the export markets by refunding the federal taxes levied on their export sale, intervention of the federal government to reduce incentives to imports at local ports, increases in import duties on certain products, including polyethylene, and the reduction in the rates of Social Integration Program ( Programa de Integração Social ), or PIS, a federal value-added tax, and Contribution for Social Security Financing ( Contribuição para Financiamento da Seguridade Social ), or COFINS, taxes on feedstock purchases by first- and second-generation petrochemical producers.

These taxes on feedstock purchase were set at a rate of 5.6% for naphtha and 9.25% for other feedstocks prior to June 2013, when they were lowered to 1% until 2015, increasing to 3% in 2016 and 5% in 2017 and, then return to the 5.6% rate in 2018 and on. We cannot predict or control which policies will be renewed or discontinued and whether future changes to Brazilian industrial policy will be proposed and enacted in the future. If industrial policies that benefit us expire, or policies detrimental to us are implemented, our business, results of operations and financial condition may be adversely affected.

Fluctuations in the real /U.S. dollar exchange rate could increase inflation in Brazil, raise the cost of servicing our foreign currency-denominated debt and negatively affect our overall financial performance.

The exchange rate between the real and the U.S. dollar and the relative rates of depreciation and appreciation of the real have affected our results of operations and may continue to do so.

The Brazilian currency has been devalued on several occasions during the last four decades. Throughout this period, the Brazilian government has implemented various economic plans and various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system. From time to time, there have been significant fluctuations in the exchange rate between the Brazilian currency and the U.S. dollar and other currencies. The real depreciated by 12.6% against the U.S. dollar during 2011, by 8.9% during 2012, by 14.6% during 2013, by 13.4% during 2014 and by 47.0% during 2015.

Depreciation of the real relative to the U.S. dollar also could result in inflationary pressures in Brazil by generally increasing the price of imported products and services. On the other hand, the appreciation of the real against the U.S. dollar may lead to a deterioration of the country’s current account and the balance of payments and may dampen export-driven growth.

We had total foreign currency-denominated debt obligations, all of which were denominated in U.S. dollars, in an aggregate amount of R$21,293.8 million (US$5,453.2 million) as of December 31, 2015, representing 77.9% of our consolidated indebtedness, net of transaction costs[delete comma]. This indebtedness does not include (i) an aggregate amount of R$1,111.6 million (US$284.7 million) outstanding as of December 31, 2015 in connection with derivatives transactions (including interest rate swaps, exchange rate swaps and currencyoptions), and (ii) an aggregate amount of R$12,277.4 million (US$3,144.2 million) outstanding as of December 31, 2015 in connection with the project finance finance facility to fund the development of Project Ethylene XXI, or the Braskem Idesa Financing. As of December 31, 2015, we had R$4,753.8 (US$1,217.4 million) in foreign currency-denominated cash and cash equivalents, not including the aggregate amount of R$134.6 million (US$34.5 million) of Braskem Idesa’s cash and cash equivalents

Table of Contents

A significant depreciation of the real in relation to the U.S. dollar or other currencies could increase our financial expenses as a result of foreign exchange losses that we must record and could reduce our ability to meet debt service requirements of our foreign currency-denominated obligations. To enable us to more efficiently manage the effects of exchange rate fluctuations on our results, in 2013 we decided to designate part of our U.S. dollar-denominated liabilities as a hedge for our future exports.

The prices of naphtha, our most important raw material, and of some of our other raw materials, are denominated in or linked to the U.S. dollar. Naphtha accounted, directly and indirectly, for 44.4% of our consolidated cost of sales and services rendered in 2015. When the real depreciates against the U.S. dollar, the cost in reais of our U.S. dollar-denominated and U.S. dollar-linked raw materials increases, and our operating income in reais may decrease to the extent that we are unable to pass on these cost increases to our customers.

The Brazilian government’s actions to combat inflation may contribute significantly to economic uncertainty in Brazil and reduce demand for our products.

Historically, Brazil has experienced high rates of inflation. Inflation, as well as government efforts to combat inflation, had significant negative effects on the Brazilian economy, particularly prior to 1995. The inflation rate, as measured by the General Price Index—Internal Availability ( Índice Geral de Preços—Disponibilidade Interna ), or the IGP-DI, reached 2,708% in 1993. Although inflation rates have been substantially lower since 1994 than in previous periods, inflationary pressures persist. Inflation rates, as measured by the IGP-DI, were 5.0% in 2011, 8.1% in 2012, 5.5% in 2013, 3.8% in 2014 and 10.7% in 2015. The Brazilian government’s measures to control inflation have often included maintaining a tight monetary policy with high interest rates, thereby restricting availability of credit and reducing economic growth. Inflation, actions to combat inflation and public speculation about possible additional actions also may contribute to economic uncertainty in Brazil and to heightened volatility in the Brazilian securities markets.

Brazil may experience high levels of inflation in future periods. Increasing prices for petroleum, the depreciation of the real and future governmental measures seeking to maintain the value of the real in relation to the U.S. dollar may trigger increases in inflation in Brazil. Periods of higher inflation may slow the rate of growth of the Brazilian economy, which would lead to reduced demand for our products in Brazil and decreased net sales revenue. Inflation is also likely to increase some of our costs and expenses, which we may not be able to pass on to our customers and, as a result, may reduce our profit margins and net income. In addition, high inflation generally leads to higher domestic interest rates, and, as a result, the costs of servicing our real denominated debt may increase, causing our net income to be reduced. Inflation and its effect on domestic interest rates can, in addition, lead to reduced liquidity in the domestic capital and lending markets, which could adversely affect our ability to refinance our indebtedness in those markets. Any decline in our net sales revenue or net income and any deterioration in our financial condition would also likely lead to a decline in the market price of our securities, including class A preferred shares and the ADSs.

Fluctuations in interest rates could raise the cost of servicing our debt and negatively affect our overall financial performance.

Our financial expenses are affected by changes in the interest rates that apply to our floating rate debt. As of December 31, 2015, we had, among other debt obligations, R$2,061.1 million of loans and financing and debentures that were subject to the Long-Term Interest Rate ( Taxa de Juros de Longo Prazo ), or TJLP, R$1,750.3 million of loans and financing and debentures that were subject to the Interbank Deposit Certificate ( Certificado de Depósito Interbancário ), or CDI rate, and R$12,297.2 million of loans and financing that were subject to the London Interbank Offered Rate, or LIBOR.

The TJLP includes an inflation factor and is determined quarterly by the Central Bank. In particular, the TJLP and the CDI rate have fluctuated significantly in the past in response to the expansion or contraction of the Brazilian economy, inflation, Brazilian government policies and other factors. See “Item 11. Quantitative and Qualitative Disclosures about Market Risk.” A significant increase in any of these interest rates could adversely affect our financial expenses and negatively affect our overall financial performance.

Brazilian government exchange control policies could increase the cost of servicing our foreign currency-denominated debt, adversely affect our ability to make payments under our foreign currency-denominated debt obligations and impair our liquidity.

The purchase and sale of foreign currency in Brazil is subject to governmental control. Many factors could cause the Brazilian government to institute more restrictive exchange control policies, including the extent of Brazil’s foreign currency reserves, the availability of sufficient foreign exchange on the date a payment is due, the size of Brazil’s debt service burden relative to the economy as a whole, Brazil’s policy towards the International Monetary Fund and political constraints to which Brazil may be subject. A more restrictive policy could increase the cost of servicing, and thereby reduce our ability to pay, our foreign currency-denominated debt obligations and other liabilities.

Our foreign-currency debt denominated in U.S. dollars represented an aggregate of 77.9% of our consolidated indebtedness as of December 31, 2015, net of transaction costs. This indebtedness does not include (i) an aggregate amount of R$1,111.6 million (US$284.7 million) outstanding as of December 31, 2015 in connection with derivatives transactions (including interest rate swaps, exchange rate swaps and currencyoptions), and (ii) an aggregate amount of R$12,277.4 million (US$3,144.2 million) outstanding as of December 31, 2015 in connection with the Braskem Idesa FinancingIf we fail to make payments under any of these obligations, we will be in default under those obligations, which could reduce our liquidity as well as the market price of our securities, including class A preferred shares and the ADSs.

Changes in tax laws may result in increases in certain direct and indirect taxes, which could reduce our gross margin and negatively affect our overall financial performance.

The Brazilian government implements from time to time changes to tax regimes that may increase our and our customers’ tax burdens. These changes include modifications in the rate of assessments and, on occasion, enactment of temporary taxes, the proceeds of which are earmarked for designated governmental purposes. We cannot predict the changes to Brazilian tax law that may be proposed and enacted in the future. However, future changes in Brazilian tax law may result in increases in our overall tax burden, which could reduce our gross margin and negatively affect our overall financial performance.

Risks Relating to Mexico

Political and economic conditions and government policies in Mexico and elsewhere may have a material impact on our operations.

A deterioration in Mexico’s economic condition, social instability, political unrest or other adverse social developments in Mexico could adversely affect our business and financial condition. These events could also lead to increased volatility in the financial markets, thereby affecting our ability to maintain financial liquidity and service our debt. Additionally, the Mexican Government recently cut spending in response to a downward trend in international crude oil prices, and it may cut spending in the future. These cuts could adversely affect the Mexican economy and, consequently, our business, financial condition, operating results and prospects.

In the past, Mexico has experienced several periods of slow or negative economic growth, high inflation, high interest rates, currency devaluation and other economic problems. These problems may worsen or reemerge, as applicable, in the future and could adversely affect our business and ability to service our debt. A worsening of international financial or economic conditions, such as a slowdown in growth or recessionary conditions in Mexico’s trading partners, including the United States, or the emergence of a new financial crisis, could have adverse effects on the Mexican economy, our financial condition and our ability to service our debt.

Furthermore, our long-term supply agreement to purchase ethane from Pemex TRI, a state-owned Mexican company, could be terminated by them as a result of expropriation or nationalization measures taken by the Mexican government. Any termination or interruption of this supply agreement could have a material adverse effect on our results of operations or financial condition.

19

Table of Contents

Mexico has experienced a period of increasing criminal activity, which could affect our operations.

In recent years, Mexico has experienced a period of increasing criminal activity, primarily due to the activities of drug cartels and related criminal organizations. In addition, the development of the illicit market in fuels in Mexico has led to increases in theft and illegal trade in the fuels that Pemex, our principal supplier in Mexico, produces. In response, the Mexican Government has implemented various security measures and strengthened its military and police forces aimed at decreasing incidents of theft and other criminal activity directed at petrochemical facilities and petrochemical products. Despite these efforts, criminal activity continues to exist in Mexico, some of which may target our facilities and products or those of Pemex and other suppliers. These activities, their possible escalation and the violence associated with them may have a negative impact on our financial condition and results of operations.

Risks Relating to Our Equity and Debt Securities

Holders of our class A preferred shares or the ADSs may not receive any dividends or interest on shareholders’ equity.

According to our by-laws and Brazilian corporate law, we must generally pay our shareholders at least 25% of our annual net income as dividends or interest on shareholders’ equity, as calculated and adjusted under Brazilian GAAP (which, for this purpose, is identical to IFRS). This adjusted net income may be capitalized, used to absorb losses or otherwise retained as allowed under Brazilian GAAP and may not be available to be paid as dividends or interest on shareholders’ equity. The Brazilian Corporation Law allows a publicly traded company like ours to suspend the mandatory distribution of dividends in any particular year if our board of directors informs our shareholders that such distributions would be inadvisable in view of our financial condition or cash availability. Holders of our class A preferred shares or the ADSs may not receive any dividends or interest on shareholders’ equity in any given year if our board of directors makes such a determination or if our operations fail to generate net income .

Our class A preferred shares and the ADSs have limited voting rights and are not entitled to vote to approve corporate transactions, including mergers or consolidations of our company with other companies, or the declaration of dividends.

Under the Brazilian Corporation Law and our by-laws, holders of our class A preferred shares and, consequently, the ADSs are not entitled to vote at meetings of our shareholders, except in very limited circumstances. These limited circumstances directly relate to key rights of the holders of class A preferred shares, such as modifying basic terms of our class A preferred shares or creating a new class of preferred shares with superior rights. Holders of preferred shares without voting rights are entitled to elect one member and his or her respective alternate to our board of directors and our fiscal council, depending on specific circumstances provided in the Brazilian Corporation Law. Holders of our class A preferred shares and the ADSs are not entitled to vote to approve corporate transactions, including mergers or consolidations of our company with other companies, or the declaration of dividends. However, if we do not pay dividends for three consecutive years, holders of our class A preferred shares and the ADSs will be granted voting rights. See “Item 10. Additional Information—Description of Our Company’s By-laws—Voting Rights.”

Holders of the ADSs may find it difficult to exercise even their limited voting rights at our shareholders’ meetings.

Under Brazilian law, only shareholders registered as such in our corporate books may attend our shareholders’ meetings. All class A preferred shares underlying the ADSs are registered in the name of the depositary. ADS holders may exercise the limited voting rights with respect to our class A preferred shares represented by the ADSs only in accordance with the deposit agreement relating to the ADSs, which provides that voting rights are only available to ADS holders at our discretion. There are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional steps involved in communicating with ADS holders. For example, we are required to publish a notice of our shareholders’ meetings in certain newspapers in Brazil. To the extent that holders of our class A preferred shares are entitled to vote at a shareholders’ meeting, they will be able to exercise their voting rights by attending the meeting in person or voting by proxy. By contrast, holders of the ADSs will receive notice of a shareholders’ meeting by mail from the depositary following our notice to the ADR depository requesting the ADR depository to do so. To exercise their voting rights, ADS holders must instruct the depositary on a timely basis. This noticed voting process will take longer for ADS holders than for holders of class A preferred shares. If it fails to receive timely voting instructions for all or part of the ADSs, the depositary will assume that the holders of those ADSs are instructing it to give a discretionary proxy to a person designated by us to vote their ADSs, except in limited circumstances.

20

Table of Contents

In the limited circumstances in which holders of the ADSs have voting rights, they may not receive the voting materials in time to instruct the depositary to vote the class A preferred shares underlying their ADSs. In addition, the depositary and its agents are not responsible for failing to carry out the voting instructions of the holders of the ADSs or for the manner of carrying out those voting instructions. Accordingly, holders of the ADSs may not be able to exercise their voting rights, and they will have no recourse if the class A preferred shares underlying their ADSs are not voted as requested.

If holders of the ADSs exchange them for class A preferred shares, they may risk temporarily losing, or being limited in, the ability to remit foreign currency abroad and certain Brazilian tax advantages.

The Brazilian custodian for the preferred shares underlying the ADSs must obtain an electronic registration number with the Central Bank to allow the depositary to remit U.S. dollars abroad. ADS holders benefit from the electronic certificate of foreign capital registration from the Central Bank obtained by the custodian for the depositary, which permits it to convert dividends and other distributions with respect to the class A preferred shares into U.S. dollars and remit the proceeds of such conversion abroad. If holders of the ADSs decide to exchange them for the underlying preferred shares, they will only be entitled to rely on the custodian’s certificate of registration with the Central Bank for five business days after the date of the exchange. Thereafter, they will be unable to remit U.S. dollars abroad unless they obtain a new electronic certificate of foreign capital registration in connection with the preferred shares, which may result in expenses and may cause delays in receiving distributions. See “Item 10. Additional Information—Exchange Controls.”

Also, if holders of the ADSs that exchange the ADSs for our Class A preferred shares do not qualify under the foreign investment regulations, they will generally be subject to less favorable tax treatment of dividends and distribution on, and the proceeds from any sale of, our preferred shares. See “Item 10. Additional information—Exchange Controls” and “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

Restrictions on the movement of currency out of Brazil may impair the ability of holders of the 6.450% Notes due 2024, issued by Braskem Finance Limited, or the 2024 Notes, to receive interest and other payments on the notes.

The Brazilian government may impose temporary restrictions on the conversion of Brazilian currency into foreign currencies and on the remittance to foreign investors of proceeds of their investments in Brazil. Brazilian law permits the government to impose these restrictions whenever there is a serious imbalance in Brazil’s balance of payments or there are reasons to foresee a serious imbalance. The Brazilian government imposed remittance restrictions for approximately six months in 1990. Similar restrictions, if imposed in the future, would impair or prevent the conversion of interest payments on the notes from reais into U.S. dollars and the remittance of U.S. dollars abroad to holders of the 2024 Notes. The Brazilian government may take similar measures in the future.

The foreign exchange policy of Brazil may affect the ability of Braskem to make money remittances outside Brazil in respect of the guarantees.

Under current Brazilian regulations, Brazilian companies are not required to obtain authorization from the Central Bank in order to make payments under guarantees in favor of foreign persons, such as the holders of the 2024 Notes. We cannot assure you that these regulations will continue to be in force at the time Braskem is required to perform its payment obligations under the guarantees. If these regulations or their interpretation are modified and an authorization from the Central Bank is required, Braskem would need to seek an authorization from the Central Bank to transfer the amounts under the guarantees out of Brazil or, alternatively, make such payments with funds held by Braskem outside Brazil. We cannot assure you that such an authorization will be obtained or that such funds will be available. If such authorization is not obtained, we may be unable to make payments to holders of the 2024 Notes in U.S. dollars. If we are unable to obtain the required approvals, if needed for the payment of amounts owed by Braskem through remittances from Brazil, we may have to seek other lawful mechanisms to effect payment of amounts due under the notes. However, we cannot assure you that other remittance mechanisms will be available in the future, and even if they are available in the future, we cannot assure you that payment on the 2024 Notes would be possible through such mechanism.

Table of Contents

Judgments of Brazilian courts enforcing Braskem’s obligations under the guarantees would be payable only in reais .

If proceedings are brought in the courts of Brazil seeking to enforce Braskem’s obligations under the guarantees, Braskem would not be required to discharge its obligations in a currency other than reais . Any judgment obtained against Braskem in Brazilian courts in respect of any payment obligations under the guarantees would be expressed in reais . We cannot assure you that this amount in reais will afford you full compensation of the amount sought in any such litigation.

Holders of the ADSs may face difficulties in protecting their interests because we are subject to different corporate rules and regulations as a Brazilian company and our shareholders may have fewer and less well-defined rights.

Holders of the ADSs are not direct shareholders of our company and are unable to enforce the rights of shareholders under our by-laws and the Brazilian Corporation Law.

Our corporate affairs are governed by our by-laws and the Brazilian Corporation Law, which differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States, such as the State of Delaware or New York, or elsewhere outside Brazil. Even if a holder of ADSs surrenders its ADSs and becomes a direct shareholder, its rights as a holder of the class A preferred shares underlying the ADSs under the Brazilian Corporation Law to protect its interests relative to actions by our board of directors may be fewer and less well-defined than under the laws of those other jurisdictions.

Although insider trading and price manipulation are crimes under Brazilian law and are the subject of continuously evolving regulations promulgated by the CVM, the Brazilian securities markets are not as highly regulated and supervised as the U.S. securities markets or the markets in some other jurisdictions. In addition, rules and policies against self-dealing or for preserving shareholder interests may be less well-defined and enforced in Brazil than in the United States and certain other countries, which may put holders of our class A preferred shares and the ADSs at a potential disadvantage. Corporate disclosures also may be less complete or informative than for a public company in the United States or in certain other countries.

Holders of the ADSs may face difficulties in serving process on or enforcing judgments against us and other persons.

We are a corporation ( sociedade por ações ) organized under the laws of Brazil, and all of our directors and executive officers and our independent public accountants reside or are based in Brazil. Most of our assets and those of these other persons are located in Brazil. As a result, it may not be possible for holders of the ADSs to effect service of process upon us or these other persons within the United States or other jurisdictions outside Brazil or to enforce against us or these other persons judgments obtained in the United States or other jurisdictions outside Brazil. In addition, because a substantial portion of our assets and all of our directors and officers reside outside the United States, any judgment obtained in the United States against us or any of our directors or officers may not be collectible within the United States. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain conditions are met, holders may face greater difficulties in protecting their interests in the case of actions by us or our directors or executive officers than would shareholders of a U.S. corporation.

We cannot assure you that a judgment of a U.S. court for liabilities under U.S. securities laws would be enforceable in Brazil or the Cayman Islands, or that an original action can be brought in Brazil or the Cayman Islands against Braskem or Braskem Finance Limited or their respective officers and directors for liabilities under U.S. securities laws, among others.

Braskem Finance Limited is an exempted company incorporated with limited liability under the laws of the Cayman Islands. Braskem is a corporation organized under the laws of Brazil. All of the directors of Braskem Finance Limited, all of the directors and officers of Braskem and some of the advisors named herein reside in Brazil or elsewhere outside the United States, and all or a significant portion of the assets of such persons may be located

outside the United States. As a result, it may not be possible for investors to effect service of process within the United States or other jurisdictions outside Brazil upon such persons, or to enforce against such persons judgments predicated upon the civil liability provisions of the U.S. federal securities laws or the laws of such other jurisdictions. In addition, it may not be possible to bring an original action in Brazil against Braskem for liabilities under applicable securities laws. Furthermore, as most of our assets are located in Brazil, any action for enforceability of the guarantees would likely need to be validated by the courts of Brazil. We cannot assure you that such judicial validation would be obtained in a timely manner or at all.

Actual or anticipated sales of a substantial number of class A preferred shares could decrease the market prices of our class A preferred shares and the ADSs.

Sales of a substantial number of our class A preferred shares could negatively affect the market prices of our class A preferred shares and the ADSs. If, in the future, substantial sales of shares are made through the securities markets by OSP, Petrobras or other existing or future holders of class A preferred shares, the market price of our class A preferred shares and, by extension, the ADSs may decrease significantly. As a result, holders of the ADSs may not be able to sell the ADSs at or above the price they paid for them.

Holders of the ADSs or class A preferred shares in the United States may not be entitled to the same preemptive rights as Brazilian shareholders have, pursuant to Brazilian legislation, in the subscription of shares resulting from capital increases made by us.

Under Brazilian law, if we issue new shares in exchange for cash or assets as part of a capital increase, subject to certain exceptions, we must grant our shareholders preemptive rights at the time of the subscription of shares, corresponding to their respective interest in our share capital, allowing them to maintain their existing shareholding percentage. We may not legally be permitted to allow holders of ADSs or class A preferred shares in the United States to exercise any preemptive rights in any future capital increase unless (1) we file a registration statement for an offering of shares resulting from the capital increase with the SEC, or (2) the offering of shares resulting from the capital increase qualifies for an exemption from the registration requirements of the Securities Act. At the time of any future capital increase, we will evaluate the costs and potential liabilities associated with filing a registration statement for an offering of shares with the SEC and any other factors that we consider important in determining whether to file such a registration statement. We cannot assure the holders of the ADSs or class A preferred shares in the United States that we will file a registration statement with the SEC to allow them to participate in any of our capital increases. As a result, the equity interest of such holders in our company may be diluted.

Brazilian tax laws may have an adverse impact on the taxes applicable to the disposition of our ADSs and preferred shares.

According to Law No. 10,833, enacted on December 29, 2003, if a nonresident of Brazil disposes of assets located in Brazil, the transaction will be subject to taxation in Brazil, even if such disposition occurs outside Brazil or if such disposition is made to another nonresident. Dispositions of our ADSs between nonresidents, however, are currently not subject to taxation in Brazil. Nevertheless, in the event that the concept of “disposition of assets” is interpreted to include the disposition between nonresidents of assets located outside Brazil, this tax law could result in the imposition of withholding taxes in the event of a disposition of our ADSs made between nonresidents of Brazil. Due to the fact that as of the date of this annual report Law No. 10,833/2003 has no judicial guidance as to its application, we are unable to predict whether an interpretation applying such tax laws to dispositions of our ADSs between nonresidents could ultimately prevail in Brazilian courts. See “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

The relative volatility and liquidity of the Brazilian securities markets may adversely affect holders of our class A preferred shares and the ADSs.

The Brazilian securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United States and other jurisdictions, and may be regulated differently from the manner in which U.S. investors are accustomed. Factors that may specifically affect the Brazilian equity markets may limit the ability of holders of the ADSs to sell class A preferred shares underlying ADSs at a price and at a time when they wish to do so and, as a result, could negatively impact the market price of the ADSs themselves.

Developments in the international capital markets may decrease the market price of our securities, including class A preferred shares, ADSs and 2024 Notes.

The market price of our securities, including class A preferred shares, ADSs and 2024 Notes may be adversely affected by declines in the international financial markets and world economic conditions. Brazilian securities markets are influenced, to varying degrees, by economic and market conditions in other countries, especially those in Latin America.

Although economic conditions are different in each country, investors’ reaction to developments in one country may affect the securities markets and the securities of issuers in other countries, including Brazil. The recent global economic and financial crisis has had a significant negative impact on the economies of countries around the world. Developed economies like the United States have sustained some of the most direct effects while some emerging economies like China have suffered substantial but comparatively milder effects. More recently, several European economies have revealed significant macroeconomic imbalances. We cannot assure you that the market for Brazilian securities will not continue to be affected negatively by events elsewhere. Any adverse economic developments in other emerging markets may adversely affect investor confidence in securities issued by Brazilian companies, causing their market price and liquidity to suffer. Any such developments could immediately affect our ability to raise capital when needed and the market price of our securities, including class A preferred shares, ADSs and 2024 Notes.

The imposition of IOF taxes may indirectly influence the price and volatility of our ADSs and preferred shares.

Brazilian law imposes the IOF/Exchange Tax, on the conversion of reais into foreign currency and on the conversion of foreign currency into reais . The objective of this tax is to slow the pace of speculative inflows of foreign capital into the Brazilian market and the appreciation of the real against the U.S. dollar. The imposition of this tax may discourage foreign investment in shares of Brazilian companies, including our company, due to higher transaction costs, and may negatively impact the price and volatility of our ADSs and preferred shares on the NYSE and the Brazilian Securities, Commodities and Futures Exchange ( BM&FBOVESPA – Bolsa de Valores, Mercadorias e Futuros ), or BM&FBOVESPA. See “Item 10. Additional information—Taxation—Brazilian Tax Considerations.”

Because Braskem Finance Limited has no operations of its own, holders of the 2024 Notes must depend on Braskem to provide Braskem Finance Limited with sufficient funds to make payments on the 2024 Notes when due.

Braskem Finance Limited, a wholly-owned subsidiary of Braskem incorporated in the Cayman Islands, has no operations other than the issuing and making payments on the 2024 Notes and other indebtedness ranking equally with the 2024 Notes, and using the proceeds therefrom as permitted by the documents governing these issuances, including lending the net proceeds of the 2024 Notes and other indebtedness incurred by Braskem Finance Limited to Braskem and subsidiaries of Braskem. Accordingly, the ability of Braskem Finance Limited to pay principal, interest and other amounts due on the 2024 Notes and other indebtedness will depend upon our financial condition and results of operations and our subsidiaries that are creditors of Braskem Finance Limited. In the event of an adverse change in our financial condition or results of operations and our subsidiaries that are creditors of Braskem Finance Limited, these entities may be unable to service their indebtedness to Braskem Finance Limited, which would result in the failure of Braskem Finance Limited to have sufficient funds to repay all amounts due on or with respect to the 2024 Notes.

Payments on Braskem’s guarantees will be junior to Braskem’s secured debt obligations and effectively junior to debt obligations of Braskem’s subsidiaries and jointly controlled companies.

The 2024 Notes will be fully guaranteed by Braskem on an unsecured basis. The Braskem guarantees will constitute senior unsecured obligations of Braskem. The guarantees will rank equal in right of payment with all of Braskem’s other existing and future senior unsecured indebtedness. Although the guarantees will provide the holders of the 2024 Notes with a direct, but unsecured claim on Braskem’s assets and property, payment on the guarantees will be subordinated to secured debt of Braskem to the extent of the assets and property securing such debt. Payment on the guarantees will also be structurally subordinated to the payment of secured and unsecured debt and other creditors of Braskem’s subsidiaries and jointly controlled companies.

Upon any liquidation or reorganization of Braskem, any right of the holders of the 2024 Notes, through enforcement of the guarantees, to participate in the assets of Braskem, including the capital stock of its subsidiaries and jointly controlled entities, will be subject to the prior claims of Braskem’s secured creditors, and to participate in the assets of Braskem’s subsidiaries and jointly controlled entities will be subject to the prior claims of the creditors of its subsidiaries and jointly controlled entities. The indenture relating to the 2024 Notes includes a covenant limiting the ability of Braskem and its subsidiaries to create or suffer to exist liens, although this limitation is subject to significant exceptions.

As of December 31, 2015, Braskem had (1) consolidated corporate debt, net of transaction costs, of R$27,350.5 million (US$7,004.3 million), and (2) the Braskem Idesa Financing of R$12,277.4 million (US$3,144.2 million). Of the consolidated corporate debt, R$5,475.1 million (US$1,402.3 million) was unsecured debt of Braskem, R$3,727.9 million (US$954.7 million) was secured debt of Braskem, R$5,478.1 million (US$1,402.9 million) was debt of Braskem’s subsidiaries and special purpose entities (other than Braskem Finance Limited and Braskem Idesa S.A.P.I.).

Braskem conducts a portion of its business operations through subsidiaries and jointly controlled companies, including Braskem Qpar, Braskem Petroquímica (formerly Quattor Petroquímica S.A.), Braskem America and QuantiQ. In servicing payments to be made on its guarantees of the 2024 Notes, Braskem will rely, in part, on cash flows from these subsidiaries and jointly controlled companies, mainly in the form of dividend payments and interest on shareholders’ equity. The ability of these subsidiaries and jointly controlled entities to make dividend payments to Braskem will be affected by, among other factors, the obligations of these entities to their creditors, requirements of Brazilian corporate and other law, and restrictions contained in agreements entered into by or relating to these entities.

Braskem’s obligations under the guarantees are subordinated to certain statutory preferences.

Under Brazilian law, Braskem’s obligations under the guarantees are subordinated to certain statutory preferences. In the event of a liquidation, bankruptcy or judicial reorganization of Braskem, such statutory preferences, including post-petition claims, claims for salaries, wages, social security, taxes and court fees and expenses and claims secured by collateral, among others, will have preference over any other claims, including claims by any investor in respect of the guarantees. In such event, enforcement of the guarantees may be unsuccessful, and holders of the 2024 Notes may be unable to collect amounts that they are due under the 2024 Notes.

Brazilian bankruptcy laws may be less favorable to you than bankruptcy and insolvency laws in other jurisdictions.

If we are unable to pay our indebtedness, including our obligations under the guarantees, then we may become subject to bankruptcy proceedings in Brazil. The bankruptcy laws of Brazil currently in effect are significantly different from, and may be less favorable to creditors than, those of certain other jurisdictions. For example, holders of the 2024 Notes may have limited voting rights at creditors’ meetings in the context of a court reorganization proceeding. In addition, any judgment obtained against us in Brazilian courts in respect of any payment obligations under the guarantees normally would be expressed in the real equivalent of the U.S. dollar amount of such sum at the exchange rate in effect (1) on the date of actual payment, (2) on the date on which such judgment is rendered, or (3) on the date on which collection or enforcement proceedings are started against us. Consequently, in the event of our bankruptcy, all of our debt obligations that are denominated in foreign currency, including the guarantees, will be converted into reais at the prevailing exchange rate on the date of declaration of our bankruptcy by the court. We cannot assure you that such rate of exchange will afford full compensation of the amount invested in the 2024 Notes plus accrued interest.
