Although we believe that these forward-looking statements are based upon reasonable assumptions, these statements are subject to several risks and uncertainties and are made in light of information currently available to us.

It is possible that our future performance may differ materially from our current assessments due to a number of factors, including the following:

· general economic, political and business conditions in our markets, both in Brazil and abroad, including demand and prices for steel products;

· interest rate fluctuations, inflation and exchange rate movements of the real in relation to the U.S. dollar and other currencies in which we sell a significant portion of our products or in which our assets and liabilities are denominated;

· prices and availability of raw materials;

· global, national and regional competition in the steel market;

· protectionist measures imposed by steel-importing countries; and

· other factors identified or discussed under “Risk Factors.”

Our forward-looking statements are not guarantees of future performance, and actual results or developments may differ materially from the expectations expressed in the forward-looking statements. As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainty of estimates, forecasts and projections. Because of these uncertainties, potential investors should not rely on these forward-looking statements.

(1) Payment of interest on equity.

Note: the Company did not advance dividends in the 1 st and 2 nd quarter of 2009.

Brazilian Law 9,249 of December 1995 provides that a company may, at its sole discretion, pay interest on equity in addition to or instead of dividends (See Item 8 — Financial Information - Interest on Equity). A Brazilian corporation is entitled to pay its shareholders interest on equity up to the limit based on the application of the TJLP rate (Long-Term Interest Rate) to its shareholders’ equity or 50% of the net income in the fiscal year, whichever is lower. This payment is considered part of the mandatory dividend required by Brazilian Corporation Law for each fiscal year. The payment of interest on equity described herein is subject to a 15% withholding tax. See Item 10. Additional Information - Taxation.

In the fourth quarter of 2008, Gerdau launched the Dividend Reinvestment Plan (DRIP), which is a program that allows the holders of Gerdau ADRs to reinvest dividends to purchase additional ADRs in the Company, with no issuance of new shares. In January 2009, Gerdau provided its shareholders a similar program in Brazil that allows the reinvestment of dividends in additional shares, with no issuance of new shares.

D. RISK FACTORS

The Company may not successfully integrate its businesses, management, operations or products, or achieve any of the benefits anticipated from future acquisitions.

Over the years, the Company has expanded its presence mainly through acquisitions in the North American and Latin American markets. The integration of the business and opportunities stemming from entities recently acquired and those that may be acquired by the Company in the future may involve risks. The Company may not successfully integrate acquired businesses, managements, operations, products and services with its current operations. The diversion of management’s attention from its existing businesses, as well as problems that can arise in connection with the integration of the new operations may have an impact on revenue and operating results. The integration of acquisitions may result in additional expenses that could reduce profitability. The Company may not succeed in addressing these risks or any other problems encountered in connection with past and future acquisitions.

All these acquisitions generated a large amount of goodwill, which is stated in the Company’s balance sheet. The Company evaluates the recoverability of this goodwill on investments annually and uses accepted market practices, including discounted cash flow for business segments which have goodwill. A downturn in the steel market could negatively impact expectations for futures earnings, leading to the need to recognize an expense in its statement of income regarding the impairment in goodwill.

The Company may be unable to reduce its financial leverage, which could increase its cost of capital, in turn adversely affecting its financial condition or operating results.

In 2007, the international rating agencies Fitch Ratings and Standard & Poor’s classified the Company’s credit risk as “investment grade”, which gave the Company access to financing at lower borrowing rates. Due to its acquisitions in recent years, its total debt/EBITDA ratio reached the maximum normally accepted by the agencies for an “investment grade” rating. In the first half of 2009, Standard & Poor’s put Gerdau on a CreditWatch Negative listing reflecting its views of the Company’s weakening cash flow and credit metrics in the currently challenging market environment. Considering that the market conditions have been improving since the low point of December 2008 and January 2009, Standard & Poor’s believed that the Company would have the ability to strengthen its credit metrics in the second half of 2009 reiterating its “investment grade”. The gradual recovery in the Company’s operational cash generation and the efforts to reduce its levels of indebtedness during 2010 and 2011 helped the Company to maintain its credit rating. In the beginning of December 2011, Moody’s assigned the Investment Grade rating “Baa3” for all of Gerdau’s ratings, with a stable perspective. With this upgrade from Moody’s, Gerdau currently has the Investment Grade of three of principal rating agencies: Fitch Ratings, Moody’s and Standard & Poor’s.

If the Company is unable to maintain its operating and financial results, it may lose its “investment grade” rating, which could increase its cost of capital and consequently adversely affect its financial condition and operating results.

The Company’s level of indebtedness could adversely affect its ability to raise additional capital to fund operations, limit the ability to react to changes in the economy or the industry and prevent it from meeting its obligations under its debt agreements.

The Company’s degree of leverage could have important consequences, including the following:

· it may limit the ability to obtain additional financing for working capital, additions to fixed assets, product development, debt service requirements, acquisitions and general corporate or other purposes;

· it may limit the ability to declare dividends on its shares and ADSs;

· a portion of the cash flows from operations must be dedicated to the payment of interest on existing indebtedness and is not available for other purposes, including operations, additions to fixed assets and future business opportunities;

· it may limit the ability to adjust to changing market conditions and place the Company at a competitive disadvantage compared to its competitors that have less debt;

· the Company may be vulnerable in a downturn in general economic conditions;

· the Company may be required to adjust the level of funds available for additions to fixed assets; and

· Pursuant to the financial agreements, the penalty for non-compliance with such financial covenants can be a declaration of default by the creditors of the relevant loans. Furthermore, there were R$9.4 billion of the

Table of Contents

Company’s total indebtedness as of December 31, 2011 that are subject to cross-default provisions, with threshold amounts varying from US$10 million to US$100 million, depending on the agreement. Thus, there is a risk that an event of default in one single debt agreement can potentially trigger events of default in other debt agreements.

Under the terms of its existing indebtedness, the Company is permitted to incur additional debt in certain circumstances; doing so could increase the risks described above.

Unexpected equipment failures may lead to production curtailments or shutdowns.

The Company operates several steel plants in different sites. Nevertheless, interruptions in the production capabilities at the Company’s principal sites would increase production costs and reduce sales and earnings for the affected period. In addition to periodic equipment failures, the Company’s facilities are also subject to the risk of catastrophic loss due to unanticipated events such as fires, explosions or violent weather conditions. The Company’s manufacturing processes are dependent upon critical pieces of steelmaking equipment, such as its electric arc furnaces, continuous casters, gas-fired reheat furnaces, rolling mills and electrical equipment, including high-output transformers, and this equipment may, on occasion, incur downtime as a result of unanticipated failures. The Company has experienced and may in the future experience material plant shutdowns or periods of reduced production as a result of such equipment failures. Unexpected interruptions in production capabilities would adversely affect the Company’s productivity and results of operations. Moreover, any interruption in production capability may require the Company to make additions to fixed assets to remedy the problem, which would reduce the amount of cash available for operations. The Company’s insurance may not cover the losses. In addition, long-term business disruption could harm the Company’s reputation and result in a loss of customers, which could materially adversely affect the business, results of operations, cash flows and financial condition.

The interests of our controlling shareholder may conflict with the interests of our non-controlling shareholders.

Subject to the provisions of our By-Laws, our controlling shareholder has powers to:

· elect a majority of our directors and nominate executive officers, establish our administrative policy and exercise full control of our management;

· sell or otherwise transfer their shares in our Company; and

· approve any action requiring the approval of shareholders representing a majority of our outstanding capital stock, including corporate reorganization, acquisition and sale of assets, and payment of any future dividends.

By having such power, the controlling shareholder can make decisions that may conflict with the interest of the Company and other shareholders.

Non-controlling shareholders may have their stake diluted in an eventual capital increase.

If the Company decides to make a capital increase through issuance of securities, there may be a dilution of the interest of the non-controlling shareholders in the current composition of the Company’s capital.

Participation in other activities related to the steel industry may conflict with the interest of subsidiaries and affiliates.

Through its subsidiaries and affiliates, the Company also engages in other activities related to production and sale of steel products, including reforestation projects; power generation; production of coking coal, iron ore and pig iron; and fab shops and downstream operations. For having the management control in these companies, the Company’s interests may conflict with the interest of these subsidiaries and affiliates, which can even lead to new strategic direction for these businesses.

Higher steel scrap prices or a reduction in supply could adversely affect production costs and operating margins.

The main metal input for the Company’s mini-mills, which mills accounted for 76.6% of total crude steel output in 2011 (in volume), is steel scrap. Although international steel scrap prices are determined essentially by scrap prices in the U.S. local market, because the United States is the main scrap exporter, scrap prices in the Brazilian market are set by domestic supply and demand. The price of steel scrap in Brazil varies from region to region and reflects demand and transportation costs. Should scrap prices increase significantly without a corresponding increase in finished steel sale prices, the Company’s profits and margins could be adversely affected. An increase in steel scrap prices or a shortage in the supply of scrap to its units would affect production costs and potentially reduce operating margins and revenues.

Increases in iron ore and coal prices, or reductions in market supply, could adversely affect the Company’s operations.

When the prices of the raw materials, particularly iron ore and coking coal, increase, and the Company needs to produce steel in its integrated facilities, the production costs in its integrated facilities also increase. The Company uses iron ore to produce liquid pig iron at its Açominas mill, and at its Gerdau Barão de Cocais and Gerdau Divinópolis units in the state of Minas Gerais, as well as Siderperu mill, in Peru. Iron ore is also used to produce sponge iron at the Gerdau Usiba unit in the state of Bahia.

The Açominas mill is the Company’s largest mill in Brazil, and its main metal input for the production of steel is iron ore. In 2011, this unit represented 49.4% of the total crude steel output (in volume) of Gerdau’s Brazilian operations. A shortage of iron ore in the domestic market may adversely affect the steel producing capacity of its Brazilian units, and an increase in iron ore prices could reduce profit margins.

The Company has iron ore mines in the state of Minas Gerais, Brazil. To reduce the exposure to iron ore price volatility, we are investing in the expansion of the productive capacity of these mines, which we expect to meet 100% of the iron ore requirements of the Açominas mill by the end of 2012.

All of the Company’s coking coal requirements for its Brazilian units are imported due to the low quality of Brazilian coal. Coking coal is the main energy input at the Açominas mill and is used at the coking facility. Although this mill is not dependent on coke supplies, a contraction in the supply of coking coal could adversely affect the integrated operations at this site, since the Açominas mill requires coking coal to produce coke in its coking facility. The coking coal used in Açominas mill is imported from Canada, the United States, Australia and Colombia. A shortage of coking coal in the international market would adversely affect the steel producing capacity of the Açominas mill, and an increase in prices could reduce profit margins. The Company does not have long-term supply contracts for certain raw materials it uses.

The Company’s operations are energy-intensive, and energy shortages or higher energy prices could have an adverse affect.

Steel production is an energy-intensive process, especially in melt shops with electric arc furnaces. Electricity represents a significant cost component at these units, as also does natural gas, although to a lesser extent. Electricity cannot be replaced at the Company’s mills and power rationing or shortages, like those that occurred in Brazil in 2001, could adversely affect production at those units.

Natural gas is used in the reheating furnaces at the Company’s rolling mills. In the case of shortages in the supply of natural gas, the Company could in some instances change to fuel oil or LPG as an energy sources. However, these measures could increase its production costs and consequently reduce its operating margins.

A default by customers or non-receipt by the Company of claims held by financial institutions and generated by financial investment operations may adversely affect the Company’s revenues.

This risk arises from the possibility of the Company not receive amounts due to sales transactions or claims held by financial institutions generated by financial investment operations. To mitigate this risk, the Company adopts as procedures, the detailed analysis of the financial position of its customers, the establishment of a credit limit and the constantly monitoring of their balances.

Global crises and subsequent economic slowdowns like those that occurred during 2008 and 2009 may adversely affect global steel demand. As a result, the Company’s financial condition and results of operations may be adversely affected.

Historically, the steel industry has been highly cyclical and deeply impacted by economic conditions in general, such as world production capacity and fluctuations in steel imports/exports and the respective import duties. After a steady period of growth between 2004 and 2008, the marked drop in demand resulting from the global economic crisis of 2008-2009 once again demonstrated the vulnerability of the steel market to volatility of international steel prices and raw materials. That crisis was caused by the dramatic increase of high risk real estate financing defaults and foreclosures in the United States, with serious consequences for bank and financial markets throughout the world. Developed markets, such as North America and Europe, experienced a strong recession due to the collapse of real estate financings and the shortage of global credit. As a result, the demand for steel products suffered a decline in 2009, but since 2010 has been showing gradual recovery, principally in the developing economies. The economic downturn and the unprecedented turbulence seen in the global economy had a negative impact on consuming markets, affecting the business environment with respect to the following:

· Decrease in international steel prices;

11

Table of Contents

· Slump in international steel trading volumes;

· Crisis in automotive industry and infrastructure sectors; and

· Lack of liquidity, mainly in the U.S. economy.

If the Company is not able to remain competitive in these shifting markets, our profitability, margins and income may be negatively affected. Although the demand for steel products in 2010 and 2011 had shown gradual improvements, no assurance can be given that these improvements will continue through the next years. A decline in this trend could result in a decrease in Gerdau shipments and revenues.

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

The Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the course of the country’s economy. The Brazilian government’s actions to control inflation and implement other policies have involved hikes in interest rates, wage and price controls, devaluation of the currency, freezing of bank accounts, capital controls and restrictions on imports.

The Company’s operating results and financial condition may be adversely affected by the following factors and the government responses to them:

· exchange rate controls and fluctuations;

· interest rates;

· inflation;

· tax policies;

· energy shortages;

· liquidity of domestic and foreign capital and lending markets; and

· other political, diplomatic, social and economic developments in or affecting Brazil.

Uncertainty over whether the Brazilian government will change policies or regulations affecting these or other factors may contribute to economic uncertainty in Brazil and to heightened volatility in Brazilian securities markets and securities issued abroad by Brazilian issuers. These and other developments in Brazil’s economy and government policies may adversely affect the Company and its business.

Inflation and government actions to combat inflation may contribute significantly to economic uncertainty in Brazil and could adversely affect the Company’s business.

Brazil has experienced high inflation in the past. Since the implementation of the Real Plan in 1994, the annual rate of inflation has decreased significantly, as measured by the National Broad Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo, or IPCA). Inflation measured by the IPCA index was 4.5% in 2007, 5.9% in 2008, 4.3% in 2009, 5.9% in 2010 and 6.5% in 2011. If Brazil were to experience high levels of inflation once again, the country’s rate of economic growth could slow, which would lead to lower demand for the Company’s products in Brazil. Inflation is also likely to increase some costs and expenses which the Company may not be able to pass on to its customers and, as a result, may reduce its profit margins and net income. In addition, high inflation generally leads to higher domestic interest rates, which could lead the cost of servicing the Company’s debt denominated in Brazilian reais to increase. Inflation may also hinder its access to capital markets, which could adversely affect its ability to refinance debt. Inflationary pressures may also lead to the imposition of additional government policies to combat inflation that could adversely affect its business.

Variations in the foreign exchange rates between the U.S. dollar and the currencies of countries in which the Company operates may increase the cost of servicing its debt denominated in foreign currency and adversely affect its overall financial performance.

The Company’s operating results are affected by fluctuations in the foreign exchange rates between the Brazilian real, the currency in which the Company prepares its financial statements, and the currencies of the countries in which it operates.

For example, the North America Business Operation reports its results in U.S. dollars. Therefore, fluctuations in the exchange rate between the U.S. dollar and the Brazilian real could affect its operating results. The same occurs with all other businesses located outside Brazil with respect to the exchange rate between the local currency of the respective subsidiary and the Brazilian real.

The Brazilian real appreciated against the U.S. dollar by 25.5% in 2009. On December 31, 2010, the U.S. dollar/Brazilian real exchange rate was $1.00 per R$ 1.67, resulting in appreciation of 4.3% when compared to December 31, 2009. At the end of 2011 the Brazilian real had depreciated 12.6% against the U.S. dollar.

Depreciation in the Brazilian real in relation to the U.S. dollar could also result in additional inflationary pressures in Brazil, by generally increasing the price of imported products and services and requiring recessionary government policies to curb demand. In addition, depreciation in the Brazilian real could weaken investor confidence in Brazil.

The Company held debt denominated in foreign currency, mainly U.S. dollars, in an aggregate amount of R$ 10.5 billion at December 31, 2011, representing 76.6% of its gross indebtedness on a consolidated basis. On December 31, 2011, the Company held R$ 991 million in cash equivalents and short-term investments denominated in currencies different from Brazilian real. Significant depreciation in the Brazilian real in relation to the U.S. dollar or other currencies could reduce the Company’s ability to service its obligations denominated in foreign currencies, particularly since a significant part of its net sales revenue is denominated in Brazilian reais.

Export revenue and margins are also affected by fluctuations in the exchange rate of the U.S. dollar and other local currencies of the countries where the Company produces in relation to the Brazilian real. The Company’s production costs are denominated in local currency but its export sales are generally denominated in U.S. dollars. Revenues generated by exports denominated in U.S. dollars are reduced when they are translated into Brazilian real in periods during which the Brazilian currency appreciates in relation to the U.S. dollar.

Demand for steel is cyclical and a reduction in prevailing world prices for steel could adversely affect the Company’s operating results.

The steel industry is highly cyclical. Consequently, the Company is exposed to substantial swings in the demand for steel products, which in turn causes volatility in the prices of most of its products and eventually causing write downs on its inventories. In addition, the demand for steel products, and hence the financial condition and operating results of companies in the steel industry, including the Company itself, are generally affected by macroeconomic changes in the world economy and in the domestic economies of steel-producing countries, including general trends in the steel, construction and automotive industries. Since 2003, demand for steel products from developing countries (particularly China), the strong euro compared to U.S. dollar and world economic growth have contributed to a historically high level of prices for the Company’s steel products. However, these relatively high prices may not last, especially due to expansion in world installed capacity or a new level of demand. In the second half of 2008, and especially in the beginning of 2009, the U.S. and European economies showed strong signs of slow down, in turn affecting many other countries. Since the end of 2009 and throughout 2010 and 2011, the world steel demand and prices have been improving if compared to the beginning of 2009 and the Company believes that this trend will continue throughout 2012. A material decrease in demand for steel or exports by countries not able to consume their production, as happened in 2008, could have a significant adverse effect on the Company’s operations and prospects.

Less expensive imports from other countries into Brazil may adversely affect the Company’s operating results.

Steel imports in Brazil caused downward pressure on steel prices in 2010, adversely affecting sales and profit margins, especially in the fourth quarter. Competition from foreign steel producers is a threat and may grow due to an increase in foreign installed steel capacity, depreciation of the U.S. dollar and a reduction of domestic steel demand in other markets, with these factors leading to higher levels of steel imports into Brazil at lower prices. Any change in the factors mentioned above, as well as in duties or protectionist measures could result in a higher level of imports into Brazil, resulting in pressures on the domestic prices that could adversely impact our business. During 2011, as a result of higher international prices, the domestic price premium compared to the international price was reduced, avoiding thereby the importation of long steel products and permitting a recovery in the domestic market prices which had been

13

Table of Contents

pressured by increased raw material costs. The Company believes that the actions adopted in the end of 2010 will reduce the exposure to this risk.

New Entrants into the Brazilian market can affect the Company’s competitiveness.

Since 2009, the intention of installing new steel production capacity in Brazil has been announced by a number of players in the industry. If effected, these installations could result in a possible loss of market share, reduction of prices and shortage of raw materials with the resulting increase in their prices.

Our mineral resource estimates may materially differ from mineral quantities that we may be able to actually extract.

Our mining resources are estimated quantities of ore and minerals. There are numerous uncertainties inherent in estimating quantities of resources, including many factors beyond our control. Reserve engineering involves estimating deposits of minerals that cannot be measured in an exact manner, and the accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgment. In addition, estimates of different engineers may vary. As a result, no assurance can be given that the amount of mining resources will be extracted or that they can be extracted at commercially viable rates.

An increase in China’s steelmaking capacity or a slowdown in China’s steel consumption could have a material adverse effect on domestic and global steel pricing and could result in increased steel imports into the markets in which we operate.

A significant factor in the worldwide strengthening of steel pricing over the past several years has been the significant growth in steel consumption in China, which at times has outpaced that country’s manufacturing capacity to produce enough steel to satisfy its own needs. At times this has resulted in China being a net importer of steel products, as well as a net importer of raw materials and supplies required in the steel manufacturing process. A reduction in China’s economic growth rate with a resulting reduction of steel consumption, coupled with China’s expansion of steel-making capacity, could have the effect of a substantial weakening of both domestic and global steel demand and steel pricing. Moreover, many Asian and European steel producers that had previously shipped their output to China may ship their steel products to other markets in the world, which could cause a material erosion of margins through a reduction in pricing.

Restrictive measures on trade in steel products may affect the Company’s business by increasing the price of its products or reducing its ability to export.

The Company is a steel producer that supplies both the domestic market in Brazil and a number of international markets. The Company’s exports face competition from other steel producers, as well as restrictions imposed by importing countries in the form of quotas, ad valorem taxes, tariffs or increases in import duties, any of which could increase the costs of products and make them less competitive or prevent the Company from selling in these markets. There are no assurances that importing countries will not impose quotas, ad valorem taxes, tariffs or increase import duties.

Costs related to complying with environmental regulations may increase if requirements become more stringent, which may adversely affect the Company’s operating results.

The Company’s industrial plants are required to comply with a number of federal, state and municipal environmental laws and regulations with respect to the environment and the operation of mills in every country in which the Company operates. These regulations include environmental licensing procedures, the control of air emissions, waste water discharges and solid and hazardous waste handling and disposal. Failure to comply with these laws and regulations may result in civil and administrative penalties, criminal sanctions or closure orders, and in various circumstances requires the cleanup of the contamination. If existing laws or future legislation become more stringent, expenditure on fixed assets and the costs of compliance may rise, adversely affecting the Company’s financial condition. Furthermore, the Company may be subject to additional expenditures and costs associated with environmental compliance as a result of future acquisitions.

Laws and regulations intended to reduce greenhouse gases and other air emissions may be enacted in the future and could have a material adverse effect on the Company’s results of operations, cash flows and financial condition.

One of the possible effects of the expansion of CO2 emission requirements is an increase in costs, mainly resulting from demand for renewable energy and implementation of new technology throughout the productive chain. However, we also estimate an increase in demand for products that result in lower emissions and a tendency within the steel sector towards demand for products made through processes that reduce green house gas emissions. It is within this scenario that Brazil Business Operations received the Falcão Bauer ecological seal for civil construction products. This

certification guarantees that the Company follows sustainable environmental factors in the production of its steel products. Moreover, Gerdau has invested funds to increase solid biofuel consumption as a source of energy in the production of pig-iron. At the same time, the Company has increased its efforts to control and manage CO2 inventories, which include the use of a number of different technologies.

Published in December 2010, Decree 7,390/2010 laid out regulations for the National Police on Climate Change, seeking to establish sector plans to mitigate and adapt to climate change in the steel sector, in order to consolidate a low carbon consumption economy. These sector plans will be prepared by December 15, 2011 by sector companies in partnership with the government and will include goals for the reduction of emissions in 2020, including gradual measures at three-year intervals, which may demand a material investment by the Company.

The Company expects operations overseas to be affected by future federal, state and provincial laws related to climate change, seeking to deal with the question of green house gas emissions (GHG) and other atmospheric emissions. The provincial governments of Canada, for example, are in the process of implementing legislative measures in the near future, some of which have already become effective. Most likely, one of the effects of this increase in legal requirements will be an upturn in energy costs. Some state governments in the United States, including the governments of California and a growing coalitions of states in the West, Northeast and Mid-Atlantic regions, are also taking active measures to reduce GHG emissions, while the United States’ federal government is also making moves towards the same form of legislation. Particularly, several pieces of federal legislation limiting greenhouse gas emissions have been presented to the US Congress, some of which could become laws in the future. The American Environmental Protection Agency (EPA) has issued a report stating that current and projected atmospheric concentrations of certain GHGs are a threat to the health and well-being of the public, which could be used as a basis for future action by the Agency. The Canadian government is also closely monitoring events in the United States and has indicated that it intends to work with the U.S. in future initiatives to reduce GHGs and increase the generation of renewable energy. As the details of this legislative platform remain undefined in both the U.S. and Canada, the result could have a negative impact on the Company’s operations, cash flow and financial situation.

Layoffs in our labor force have generated severance costs, and such layoffs could reoccur.

A substantial number of our employees are represented by labor unions and are covered by collective bargaining or other labor agreements, which are subject to periodic negotiation. Strikes or work stoppages have occurred in the past and could reoccur in connection with negotiations of new labor agreements or during other periods for other reasons, including the risk of layoffs during a down cycle that could generate severance costs. Moreover, we could be adversely affected by labor disruptions involving unrelated parties that may provide us with goods or services. Strikes and other labor disruptions at any of our operations could adversely affect the operation of facilities and the timing of completion and the cost of capital of our projects.

Developments and the perception of risks in other countries, especially in the United States and emerging market countries, may adversely affect the market prices of our preferred shares and ADSs.

The market for securities issued by Brazilian companies is influenced, to varying degrees, by economic and market conditions in the United States and emerging market countries, especially other Latin American countries. Although economic conditions are different in each country, the reaction of investors to economic developments in one country may cause the capital markets in other countries to fluctuate. Developments or adverse economic conditions in other emerging market countries have at times resulted in significant outflows of funds from, and declines in the amount of foreign currency invested in Brazil.

The Brazilian economy is also affected by international economic and market conditions, especially economic and market conditions in the United States. Share prices on the BMF&FBOVESPA, for example, have historically been sensitive to fluctuations in United States interest rates as well as movements of the major United States stocks indexes.

Economic developments in other countries and securities markets could adversely affect the market prices of our preferred shares or the ADSs, could make it more difficult for us to access the capital markets and finance our operations in the future on acceptable terms or at all, and could also have a material adverse effect on our operations and prospects.

Less expensive imports from other countries into North America and Latin America may adversely affect the Company’s operating results.

Steel imports in North America and Latin America have forced a reduction in steel prices in the last several years, adversely affecting sales and profit margins. The competition of foreign steel producers is strong and may increase due to the increase in their installed capacity, the depreciation of the U.S. dollar and the reduced domestic demand for steel in other markets, with those factors leading to higher levels of steel imports into North and Latin America at lower prices. In the past, the United States government adopted temporary protectionist measures to control the import of steel

by means of quotas and tariffs. Some Latin American countries have adopted similar measures. These protectionist measures may not be adopted and, despite efforts to regulate trade, imports at unfair prices may be able to enter into the North American and Latin American markets, resulting in pricing pressures that may adversely affect the Company’s results.

ITEM 4. COMPANY INFORMATION

A. HISTORY AND DEVELOPMENT OF THE COMPANY

Gerdau S.A. is a Brazilian corporation (Sociedade Anônima) that was incorporated on November 20, 1961 under the laws of Brazil. Its main registered office is located at Av. Farrapos, 1811, Porto Alegre, Rio Grande do Sul, Brazil, and the telephone number is +55 (51) 3323 2000.

History

The current Company is the product of a number of corporate acquisitions, mergers and other transactions dating back to 1901. The Company began operating in 1901 as the Pontas de Paris nail factory controlled by the Gerdau family based in Porto Alegre, who is still the Company’s indirect controlling shareholder. In 1969, Pontas de Paris was renamed Metalúrgica Gerdau S.A., which today is the holding company controlled by the Gerdau family through intermediate holding companies that in turn controls what is today Gerdau S.A.

From 1901 to 1969, the Pontas de Paris nail factory grew and expanded its business into a variety of other steel and steel-related products and services. At the end of World War II, the Company acquired Siderúrgica Riograndense S.A., a steel producer also located in Porto Alegre, in an effort to broaden its activities and provide it with greater access to raw materials. In February 1948, the Company initiated its steel operations, which foreshadowed the successful mini-mill model of producing steel in electric arc furnaces using steel scrap as the main raw material. At that time the Company adopted a regional sales strategy to ensure more competitive operating costs. In 1957, the Company installed a second unit in the state of Rio Grande do Sul in the city of Sapucaia do Sul, and in 1962, steady growth in the production of nails led to the construction of a larger and more advanced factory in Passo Fundo, also in Rio Grande do Sul.

In 1967, the Company expanded into the Brazilian state of São Paulo, purchasing Fábrica de Arames São Judas Tadeu, a producer of nails and wires, which was later renamed Comercial Gerdau and ultimately became the Company’s Brazilian distribution channel for steel products. In June 1969, the Company expanded into the Northeast of Brazil, producing long steel at Siderúrgica Açonorte in the state of Pernambuco. In December 1971, the Company acquired control of Siderúrgica Guaíra, a long steel producer in the state of Paraná in Brazil’s South Region. The Company also established a new company, Seiva S.A. Florestas e Indústrias, to produce lumber on a sustainable basis for the furniture, pulp and steel industries. In 1979, the Company acquired control of the Cosigua mill in Rio de Janeiro, which currently operates the largest mini-mill in Latin America. Since then, the Company has expanded throughout Brazil with a series of acquisitions and new operations, and today owns 15 steel units in Brazil.

In 1980, the Company began to expand internationally with the acquisition of Gerdau Laisa S.A., the only long steel producer in Uruguay, followed in 1989 by the purchase of the Canadian company Gerdau Ameristeel Cambridge, a producer of common long rolled steel products located in Cambridge, Ontario. In 1992, the Company acquired control of Gerdau AZA S.A., a producer of crude steel and long rolled products in Chile. Over time, the Company increased its international presence by acquiring a non-controlling interest in a rolling mill in Argentina, a controlling interest in Diaco S.A. in Colombia, and, most notably, additional interests in North America through the acquisition of Gerdau Ameristeel MRM Special Sections, a producer of special sections such as elevator guide rails and super light beams, and the former Ameristeel Corp., a producer of common long rolled products. In October 2002, through a series of transactions, the Company merged its North American steel production assets with those of the Canadian company Co-Steel, a producer of long steel, to create Gerdau Ameristeel, which is currently the second largest long steel producer in North America based on steel production volume. Gerdau Ameristeel itself has a number of operations throughout Canada and the United States, including its 50% jointly controlled entity interest in Gallatin Steel, a manufacturer of flat steel, and also operates 18 steel units, 49 fabrication shops and 12 downstream operations.

In September 2005, Gerdau acquired 35.98% of the stock issued by Sipar Aceros S.A., a long steel rolling mill with a total installed capacity of 260,000 tonnes of rolled steel, located in the Province of Santa Fé, Argentina. This interest, added to the 38.46% already owned by Gerdau represents 74.44% of the capital stock of Sipar Aceros S.A. At the end of the third quarter of 2005, Gerdau concluded the acquisition of a 57.1% interest in Diaco S.A., the largest rebar manufacturer in Colombia. In January 2008, the Company purchased an additional interest of 40.2%, for $107.2 million (R$ 188.7 million on the acquisition date).

In January 2006, through its subsidiary Gerdau Hungria Holdings Limited Liability Company, Gerdau acquired

In June 2006, Gerdau acquired for $103.0 million (R$ 224.5 million) Sheffield Steel Corporation in Sand Springs, Oklahoma in the USA. Sheffield is a mini-mill producer of common long steel, namely concrete reinforcement bars and merchant bars. It has one melt shop and one rolling mill in Sand Springs, Oklahoma, one rolling mill in Joliet, Illinois and three downstream units in Kansas City and Sand Springs.

In the same month, Gerdau S.A. won the bid for 50% plus one share of the capital stock of Empresa Siderúrgica Del Perú S.A.A. (Siderperú) located in the city of Chimbote in Peru for $60.6 million (R$ 134.9 million). In November 2006, Gerdau also won the bid for 324,327,847 shares issued by Siderperú, which represented 32.84% of the total capital stock, for $40.5 million, totaling $101.1 million (R$ 219.8 million). This acquisition added to the interest already acquired earlier in the year, for an interest of 83.27% of the capital stock of Siderperú. Siderperú operates a blast furnace, a direct reduction unit, with a total installed capacity of 400,000 tonnes of pig iron, a melt shop with two electric arc furnaces, two LD converters and three rolling mills.

In November 2006, the Company completed the acquisition of a 55% controlling interest in Pacific Coast Steel (“PCS”), for $104.0 million (R$ 227.4 million). The company operates rebar fabrication plants in San Diego, San Bernardino, Fairfield, and Napa, California. Additionally, in April, 2008 Gerdau increased its stake in PCS to 84% paying $82.0 million (R$ 138.4 million). The acquisition of PCS expanded the Company’s operations to the West Coast of the United States and also added rebar placing capability.

In March 2007, Gerdau acquired Siderúrgica Tultitlán, a mini mill located in the Mexico City metropolitan area that produces rebar and profiles with installed capacity of 500,000 tonnes of crude steel and 340,000 tonnes of rolled steel. The price paid for the acquisition was $259.0 million (R$ 536.0 million).

In May 2007, Gerdau acquired an interest of 30.45% in Multisteel Business Holdings Corp., a holding of Indústrias Nacionales, C. por A. (“INCA”), a company located in Santo Domingo, Dominican Republic. INCA is a producer of rolled products, with annual capacity of approximately 300,000 tonnes of rolled steel. This partnership allowed the Company to access the Caribbean market. The total cost of the acquisition was $42.9 million (R$ 82.0 million). In July 2007, the Company acquired an additional interest of 18.55% in Multisteel Business Holdings Corp., bringing its total interest in the Company to 49%. The total cost of this second acquisition was $72.0 million (R$ 135.2 million).

In June 2007, Gerdau acquired 100% of the capital stock of Siderúrgica Zuliana C.A., a Venezuelan company operating a steel mill in the city of Ojeda, Venezuela. The total cost of the acquisition was $92.5 million (R$ 176.2 million).

In the same month, Gerdau and the Kalyani Group from India initiated an agreement to establish a jointly controlled entity for an investment in Tadipatri, India. The jointly controlled entity included an interest of 45% in Kalyani Gerdau Steel Ltd., a producer of steel with two LD converters, one continuous casting unit and facilities for the production of pig iron. The agreement provides for shared control of the jointly controlled entity, and the purchase price was $73.0 million (R$ 127.3 million). In May 2008, Gerdau announced the conclusion of this acquisition.

In September 2007, Gerdau Ameristeel concluded the acquisition of Chaparral Steel Company, increasing the Company’s portfolio of products and including a comprehensive line of structural steel products. Chaparral operates two mills, one located in Midlothian, Texas, with a total installed capacity of 1.5 million tonnes of crude steel and 1.4 million tonnes of rolled steel and the other located in Petersburg, Virginia, with a total installed capacity of 1.0 million tonnes of crude steel and 1.0 million tonnes of rolled steel. The total cost of the acquisition was $4.2 billion (R$ 7.8 billion), plus the assumption of certain liabilities.

In October 2007, Gerdau Ameristeel acquired 100% of Enco Materials Inc., a leading company in the market of commercial materials headquartered in Nashville, Tennessee. Enco Materials Inc. has eight units located in Arkansas, Tennessee and Georgia. The purchase price for this acquisition was $46 million (R$ 84.9 million) in cash, plus the

17

assumption of certain liabilities of the acquired company.

In the same month, Gerdau executed a letter of intent for the acquisition of an interest of 49% in the capital stock of the holding company Corsa Controladora, S.A. de C.V., headquartered in Mexico City, Mexico. The holding company owns 100% of the capital stock of Aceros Corsa, S.A. de C.V. and its distributors. Aceros Corsa, located in the city of Tlalnepantla in the Mexico City metropolitan area, is a mini-mill responsible for the production of long steel (light commercial profiles). The acquisition price was $110.7 million (R$ 186.3 million). In February, 2008, the Company announced conclusion of this acquisition.

In November 2007, Gerdau entered into a binding agreement for the acquisition of the steel company MacSteel from Quanex Corporation. MacSteel is the second largest producer of Special Bar Quality (SBQ) in the United States and operates three mini-mills located in Jackson, Michigan; Monroe, Michigan; and Fort Smith, Arkansas. The Company also operates six downstream operations in the states of Michigan (two), Ohio, Indiana (two) and Wisconsin. MacSteel has annual installed capacity of 1.2 million tonnes of crude steel and 1.1 million tonnes of rolled products. The agreement did not include the Building Products business of Quanex, which is an operation not related to the steel market. The purchase price for this acquisition was $1.5 billion (R$ 2.4 billion) in addition to the assumption of their debts and some liabilities. Gerdau concluded the acquisition in April, 2008.

In January 2008, Gerdau acquired an additional interest of 40.2% in the capital of Diaco S.A. for $107.2 million (R$ 188.7 million on the date of the acquisition), increasing its interest to 98.7% of the capital stock, a figure that also takes into consideration the dilution of a non-controlling interests, which explains the higher percentage in comparison with the percentages of the two major acquisitions made.

In April 2008, Gerdau entered into a strategic partnership with Corporación Centroamericana del Acero S.A., assuming a 30.0% interest in the capital of this company. The Company owns assets in Guatemala and Honduras as well as distribution centers in El Salvador, Nicaragua and Belize. The price of the acquisition was $180 million (R$ 303.7 million).

In June, 2008, the parent company Metalúrgica Gerdau S.A. acquired a 28.88% stake of voting and total capital in Aços Villares S.A. from BNDESPAR for R$ 1.3 billion. As a payment, Metalúrgica Gerdau S.A. issued debentures to be exchanged for Gerdau S.A.’s preferred shares. In December, 2009 the Company’s stake in Aços Villares S.A. owned through its subsidiary Corporación Sidenor S.A. was transferred to direct control of Gerdau S.A., for US$ 218 million (R$ 384 million), which then owned a total 58.5% stake in Aços Villares S.A. In December 30, 2010, Gerdau S.A. and Aços Villares S.A. shareholders approved the merger into Gerdau S.A. of Aços Villares S.A.

Also in 2008, Gerdau invested in the verticalization of its businesses. In July, it acquired a 50.9% stake in the capital of Cleary Holdings Corp, which controls a metallurgical coke producer and coking coal reserves in Colombia for $ 73.0 million (R$ 119.3 million).

In December 2008, Gerdau Hungria Holding Limited Liability Company acquired Lux Fin Participation S.L. for $288.0 million (R$ 674.0 million), which indirectly holds a 20% interest in Corporación Sidenor. As a result of this acquisition, Gerdau became the majority shareholder (60%) of Corporación Sidenor.

On August 12, 2010, Gerdau S.A. concluded the acquisition of the remaining interest of 49.1% in the total capital of Cleary Holdings Corp. for US$57 million. Cleary Holdings Corp. has annual metallurgical coke production capacity of 1.0 million tonnes and estimated coking coal reserves of 20 million tonnes. Its total production is currently allocated to the export market. This acquisition was consistent with the strategy of guaranteeing the supply of coking coal or metallurgical coke for steel production at Gerdau´s integrated plants.

On August 30, 2010, Gerdau S.A. concluded the acquisition of all outstanding common shares issued by Gerdau Ameristeel that it did not yet hold either directly or indirectly, for $11.00 per share in cash, corresponding to a total of $1.6 billion (R$ 2.8 billion). With the acquisition, Gerdau Ameristeel was delisted from the New York and Toronto stock exchanges.

On October 21, 2010, Gerdau S.A. concluded, through its wholly-owned subsidiary Gerdau Ameristeel, the acquisition of Tamco, a company based in the state of California. TAMCO is a mini-mill that produces rebars and is one of the largest producers on the West Coast of the United States, with annual capacity of approximately 500,000 tonnes. The acquisition price was approximately US$ 166.4 million (R$ 283.1 million).

On December 30, 2010, the shareholders of Gerdau S.A. and Aços Villares S.A. approved the merger of Aços Villares S.A. with Gerdau S.A. The transaction was carried out through a share exchange, whereby the shareholders of Aços Villares S.A. received one share in Gerdau S.A. for each lot of twenty-four shares held. The new shares were credited on February 10, 2011. As a result of the transaction, Aços Villares S.A. was delisted from the Brazilian stock

exchange. Following the issue of new shares under the merger, on February 30, 2011, the capital stock of Gerdau S.A. was represented by 505,600,573 common shares and 1,011,201,145 preferred shares.

B. BUSINESS OVERVIEW

Steel Industry

The world steel industry is composed of hundreds of steel producing installations and is divided into two major categories based on the production method utilized: integrated steel mills and non-integrated steel mills, sometimes referred to as “mini-mills”. Integrated steel mills normally produce steel from iron oxide, which is extracted from iron ore melted in blast furnaces, and refine the iron into steel, mainly through the use of basic oxygen furnaces or, more rarely, electric arc furnaces. Non-integrated steel mills produce steel by melting in electric arc furnaces scrap steel, which occasionally is complemented by other metals such as direct-reduced iron or hot-compressed iron. According to World Steel Association, in 2010 (last information available), 28.7% of the total crude steel production in the world was through mini-mill process and the remaining 71.3% was through the integrated process.

*Last information available

Over the past 15 years, according to World Steel Association, total annual crude steel production has grown from 799 million tonnes in 1997 to 1,527 million tonnes in 2011, for an average annual increase of 4.3%, with a large part of this growth occurring after 2000.

The main factor responsible for the increase in the demand for steel products has been China. Since 1993, China has become the world’s largest steel market and currently consumes as much as the United States and Europe combined.

Over the past year, total annual crude steel production increased by 6.8% from 1,429.9 million tonnes in 2010 to 1,526.9 million tonnes in 2011, triggered mainly by steel production recovery in nearly all the major steel producing countries and regions including South America, Asia and Middle East.

The Brazilian Steel Industry

Since 1940, steel has been of vital importance to Brazil’s economy. For approximately 50 years, the Brazilian government held a monopoly in the production of flat steel products via the state-owned company Siderúrgica Brasileira S.A. (SIDEBRÁS). But the Brazilian government did not hold a monopoly in the non-flat steel industry, traditionally composed mainly of small private companies. The principal integrated producers of flat steel products operated as semi-independent companies under the control of SIDEBRÁS. During the 1970s, the government invested heavily to give Brazil a steel industry capable of fueling the country’s industrialization process. After a decade of practically no investments in this industry, the government selected steel as the first industry to be sold in the privatization process that began in 1991.

In 2011, Brazil maintained its position as the world’s 9th largest producer of crude steel, with a production of 35.2 million tonnes, a 2.3% share of the world market and 72.7% of the total steel production in Latin America during that year.

Total sales of Brazilian steel products were 31.7 million tonnes in 2011, 29.5 million tonnes in 2010 and 25.0 million tonnes in 2009, exceeding domestic demand of 25.2 million in 2011, 26.6 million tonnes in 2010 and 18.7 million tonnes in 2009. In 2011, total steel sales in the domestic market increased 3.3% compared to 2010, from 20.2 million tonnes to 20.9 million tonnes.

The breakdown of total sales of Brazilian steel products in 2011 was 62.1% or 19.7 million tonnes of flat steel products, formed by domestic sales of 11.3 million tonnes and exports of 8.4 million tonnes. The other 37.9% or 12.0 million tonnes represented sales of long steel products, which were formed by domestic sales of 9.6 million tonnes and exports of 2.4 million tones.

Domestic demand - Historically, the Brazilian steel industry has been affected by significant variations in domestic steel demand. Although per capita domestic consumption varies in accordance with Gross Domestic Product (GDP), variations in steel consumption tend to be more accentuated than changes in the level of economic growth. In 2010, Brazilian GDP increased by 3.8%, grew by 7.5% in 2010 and decreased by 0.6% in 2009. Per capita crude steel consumption in Brazil increased from 89 kilos in 2005 to 134 kilos in 2011, which is still considered low compared to the levels in developed countries.

Exports and imports — Over the past 20 years, the Brazilian steel industry has been characterized by a structural need for exports. The Brazilian steel market has undergone periods of excess capacity, cyclical demand and intense competition in recent years. Demand for finished steel products, based on apparent domestic consumption, has lagged total supply (total production plus imports).

In 2011, Brazilian steel exports totaled 10.8 million tonnes, representing 34.1% of total sales (domestic sales plus exports). Brazil has performed an important role in the world export market, principally as an exporter of semi-finished products (slabs, blooms and billets) for industrial use or for re-rolling into finished products. Brazilian exports of semi-finished products totaled 7.3 million tonnes in 2011, 5.5 million tonnes in 2010 and 4.7 million tonnes in 2009, representing 67.6%, 59.8% and 54.7% of Brazil’s total exports of steel products, respectively.

Production and Apparent Demand for Steel Products (million tonnes)

Source: worldsteel/Short Range Outlook

Brazil used to be a small importer of steel products. Considering the reduction in the international steel prices during 2010, the appreciation of the Brazilian real against the U.S. dollar and the decrease in demand for steel products in developed countries, the Brazilian levels of imports increased from 2.3 million tonnes in 2009 to 5.9 million tonnes in 2010 (excluding the imports made by the steel mills to avoid double counting), representing 22.0% of apparent domestic consumption. In 2011, imports reduced to 3.8 million tones, representing 15.1% of apparent domestic consumption.

Raw materials - One of Brazil’s major competitive advantages is the low cost of its raw materials. Brazil has an abundance of high quality iron ore. Various integrated producers are located in the state of Minas Gerais, where some of the world’s biggest iron ore mines are located. The cost of iron ore in Brazil is approximately one-fifth of the cost in China and one-third of the cost in United States.

In Brazil, most of the scrap metal utilized by the steel mills comes from the state of São Paulo. Its suppliers deliver scrap metal derived from obsolete products directly to the steel mills. The Brazilian steel industry’s dependence on scrap metal is minimal, due to the high percentage of total steel production coming from integrated producers.

Brazil is a net producer of pig iron. Most of Brazil’s pig iron is produced in the state of Minas Gerais by several small producers. In Brazil, the price of pig iron is related to the cost of charcoal, an important input and the most volatile component in pig iron’s production cost. When the price of charcoal is high, coking coal can be used as a substitute and, although more expensive, it produces more pig iron. Practically all the coking coal is imported because domestic supplies are considered low quality.

North American Steel Industry

The global steel industry is highly cyclical and competitive due to the large number of steel producers, the dependence upon cyclical end markets and the high volatility of raw material and energy prices. The North American steel industry is currently facing a variety of challenges, including volatile pricing, high fixed costs, low priced imports and the diminution of the effect of U.S. tariffs. The future success of North American steel producers is dependent upon numerous factors, including general economic conditions, levels and prices of steel imports and the strength of the U.S. dollar.

Crude Steel Production by North American Countries (million tonnes)

Source: worldsteel/monthly statistics

Beginning in mid-2000 and continuing through 2002, the North American steel industry experienced a severe downward cycle due to excess global production capacity, high import levels at low prices, including prices that were below the combined costs of production and shipping, and weak general economic conditions. These forces resulted in lower domestic steel prices and significant domestic capacity closures. Prices for many steel products reached 10-year lows in late 2001. As a result of these conditions, over 20 U.S. steel companies sought protection under Chapter 11 of the United States Bankruptcy Code since the beginning of 2000.

In response to these conditions, in March 2002, Former President Bush imposed a series of tariffs and quotas on certain imported steel products under Section 201 of the Trade Act of 1974. These measures were intended to give the domestic steel industry an opportunity to strengthen its competitive position through restructuring and consolidation. On November 10, 2003, the World Trade Organization (“WTO”) Appellate Body issued a ruling that upheld an initial WTO panel ruling that declared the Section 201 tariffs on steel imports to be in violation of WTO rules concerning safeguard measures. On December 4, 2003, Former President Bush signed a proclamation terminating the steel safeguard tariffs, and announced that the tariffs had achieved their purpose and changed economic circumstances indicated it was time to terminate them. International trade negotiations, such as the ongoing Organization for Economic Cooperation and Development steel subsidy agreement negotiations and the WTO Doha Round negotiations, may affect future international trade rules with respect to trade in steel products.

The North American steel industry has experienced a significant amount of consolidation in the last decade. Bankrupt steel companies, once overburdened with underfunded pension, healthcare and other legacy costs, are being relieved of obligations and purchased by other steel producers. This consolidation, including the purchases of the assets of LTV Corporation, Bethlehem Steel Corporation, Trico Steel Co. LLC and National Steel Corporation, has created a lower operating cost structure for the resulting entities and a less fragmented industry. In the bar sector in 2002, the combination of Gerdau North America and Co-Steel in October 2002 and Nucor Corporation’s acquisition of Birmingham Steel Corporation in February 2002 significantly consolidated the market. The Company’s acquisition of the North Star Steel assets from Cargill in November 2004, Sheffield Steel Corporation in 2006 and Chaparral Steel Company in September 2007, have further contributed to this consolidation trend. Since the beginning of 2007, Tata Iron and Steel Co. Ltd. acquired Corus Group PLC, SSAB Svenskt Staal AB acquired Ipsco Inc., Essar Global Ltd. acquired Algoma Steel Inc., United States Steel Corporation acquired Stelco Inc., and Arcelormittal Inc. acquired Bayou Steel Corporation. The Company believes continued consolidation in the North American steel industry will occur over the next several years, resulting in the creation of larger steel companies, the reduction of operating cost structures and further rationalization among steel producers.

The creation of larger and more efficient steel producers resulting from consolidation in the steel industry has strongly contributed to maintenance of profitability in the long term. As a result, the remaining steel producers have become better positioned to tailor production capacity to market demand and have benefited from scale efficiencies. Such factors have improved steel producers’ ability to reduce costs, negotiate raw material contracts and better respond to the cyclical nature of the steel industry. In addition, the increase in domestic competition from imports observed in early 2000 has diminished, primarily in response to higher steel prices globally, higher transportation costs resulting from fuel price increases and a weaker U.S. dollar.

The steel industry demonstrated strong performance through the middle of 2008, resulting from the increased global demand for steel related products and a continuing consolidation trend among steel producers. Additionally, through the same time period, the domestic U.S. market experienced a rebound in non-residential construction mainly driven by industrial and infrastructure projects (including highway, energy-related construction and water treatment plants), warehouse space, schools, hospitals and a strong retail market. Beginning in the fall of 2008, the steel industry began feeling the negative effects of the severe economic downturn brought on by the credit crisis. The economic

downturn continued through 2009 and has resulted in a significant reduction in the production and shipment of steel products in North America, as well as reduced exports of steel products from the United States to other parts of the world. During 2010 and 2011, the economy in North America has been showing signs of upturn, contributing to a gradual recovery in the steel industry, with an important improvement in the automotive sector.

Company Profile

Gerdau S.A. is a company of the Gerdau Group, mainly dedicated to the production and commercialization of steel products in general, through its mills located in Argentina, Brazil, Canada, Chile, Colombia, Spain, United States, Guatemala, India, Mexico, Peru, Dominican Republic, Uruguay and Venezuela.

Gerdau is the leading producer of long steel in the Americas and one of the main suppliers of special long steel in the world. With over 45,000 employees, Gerdau has industrial activities in 14 countries - operating in the Americas, Europe, and Asia - presenting a combined annual installed production capacity of over 25 million tons of steel. Gerdau is the largest recycler in Latin America and the world, transforming millions of tons of scrap into steel every year. With over 140,000 shareholders, Gerdau is listed on the São Paulo, New York and Madrid stock exchanges. To achieve increasing levels of profitability, the Company integrates its supply chain through a network of mills, service centers, fab shops and downstream units and distribution channels strategically positioned in the main consumption centers.

According to the Brazilian Steel Institute (IABr - Instituto Aço Brasil), Gerdau is Brazil’s largest producer of long rolled steel. Gerdau holds significant market share in the steel industries of almost all countries where it operates and has been classified by World Steel Association as the world’s 13 th largest steel producer based on its consolidated crude steel production in 2010.

Gerdau operates steel mills that produce steel by direct iron-ore reduction (DRI) in blast furnaces and in electric arc furnaces (EAF). In Brazil it operates four integrated steel mills, including its largest mill, Açominas mill, an integrated steel mill located in the state of Minas Gerais. The Company currently has a total of 60 steel producing units globally, including jointly controlled entities and associate companies. The jointly controlled entity includes a unit located in the United States for the production of flat rolled steel and another unit in India. The associate companies are Aceros Corsa in Mexico; Corporación Centroamericana del Acero in Guatemala; and INCA in the Dominican Republic.

As of December 31, 2011, total consolidated installed capacity, excluding the Company’s investments in jointly controlled entities and associate companies, was 25.3 million tonnes of crude steel and 21.3 million tonnes of rolled steel products. In the same period, the Company had total consolidated assets of R$ 50.0 billion, consolidated net sales of R$ 35.4 billion, total consolidated net income (including non-controlling interests) of R$ 2.1 billion and shareholders’ equity (including non-controlling interests) of R$ 26.5 billion.

Gerdau offers a wide array of steel products, which are manufactured according to an extensive variety of customer specifications. Its product mix includes crude steel (slabs, blooms and billets) sold to rolling mills, finished products for the construction industry such as rods and structural bars, finished products for industry such as commercial rolled steel bars and machine wire and products for farming and agriculture such as poles, smooth wire and barbed wire. Gerdau also produces special steel products utilizing advanced technology and normally with a certain degree of customization for the manufacture of tools and machinery, chains, locks and springs, mainly for the automotive and mechanical industries.

A significant and increasing portion of Gerdau’s steel production assets is located outside Brazil, particularly in the United States and Canada, as well as in Latin America and Europe. The Company began its expansion into North America in 1989, when consolidation in the global steel market effectively began. The Company currently operates 19 steel production units in the United States and Canada through its principal entity, Gerdau Ameristeel, and believes that it is one of the market leaders in North America in terms of production of some long steel products, such as rods, commercial rolled steel bars, extruded products and beams.

The Company’s operating strategy is based on the acquisition or construction of steel mills located close to its customers and sources of the raw materials required for steel production, such as scrap metal, pig iron and iron ore. For this reason, most of its production has historically been geared toward supplying the local markets in which it has production operations. However, the Company also exports an important portion of its production to other countries.

Through its subsidiaries and affiliates, the Company also engages in other activities related to the production and sale of steel products, including reforestation; electric power generation projects; coking coal, iron ore and pig iron production; as well as fab shops and downstream operations.

Operations

The Company sells its products to a diversified list of customers for use in the construction, manufacturing and agricultural industries. Sales by the Company’s Brazilian operations include both domestic and export sales. Most of the sales by the Company’s business operations in North and Latin America (except Brazil) are aimed at their respective local markets.

In 2008, the Company’s Board of Directors approved the proposal of the Gerdau Executive Committee (the chief operating decision maker) related to the new governance of the Company, which established a new business segmentation, as follows:

· Brazil (Brazil Business Operation) — includes Brazil’s operations, except special steel;

· North America (North America Business Operation) — includes all North American operations, except Mexico and special steel;

· Latin America (Latin America Business Operation) — includes all Latin American operations, except for Brazil;

· Special Steel (Special Steel Business Operation) — includes the special steel operations in Brazil, Spain and the United States.

Açominas and Long Steel Brazil, previously treated as separate segments, are now reported as a single operating segment since most of their operational support areas are integrated. This means in practical effect that Long Steel Brazil sells part of the Açominas products to the domestic and export markets. In the same way, Açominas’s purchasing department is responsible for buying all of Long Steel Brazil’s iron ore needs. Furthermore, numerous other services are shared by them, including Human Resources, Information Technology, Accounting, Domestic and Export Sales, Tax and Financial departments. These are examples of the extent of integration of these operations and why the Company decided to change its governance and aggregate the information the chief operating decision maker uses to manage the business. The chief operating decision maker is no longer monitoring individual information about Açominas and Long Steel Brazil, but rather information concerning a unified operating segment styled Operation Brazil. For comparison, information as of December 31, 2008 and 2007 was modified with respect to the information originally reported in order to consider the same criteria established by the new business segmentation established by the Gerdau Executive Committee.

The following tables present the Company’s consolidated shipments in tonnage and net sales by Business Operation for the periods indicated:

Brazil Business Operation

Brazil Business Operation minimizes delays by delivering its products directly to customers through outsourced companies under Gerdau’s supervision. Sales trends in both the domestic and export markets are forecast monthly based on historical data for the three preceding months. Brazil Business Operation uses a proprietary information system to stay up-to-date on market developments so that it can respond swiftly to fluctuations in demand. Gerdau considers its flexibility in shifting between markets (Brazilian and export markets) and its ability to monitor and optimize inventory levels for most of its products in accordance with changing demand as key factors to its success.

In the Brazil Business Operation, sales volume in 2011 increased by 6.3% from 2010. Domestic sales volume grew by 7.3%, influenced by good demand in the civil construction industry. In the Brazil Business Operation, the civil construction industry has played an important role in maintaining the demand. According to Sinduscon, the civil construction industry’s GDP is expected to grow by 5% in 2012, which indicates a strong demand in this industry in the Brazilian market.

In 2011, approximately 28.2% of the production sold in Brazil was distributed through Comercial Gerdau, the Company’s largest distribution channel, with 82 stores throughout Brazil, 40 fabricated reinforcing steel facilities (Prontofer) and four flat steel service centers, serving more than 122,000 customers in the year. Another important distribution channel is the network of more than 26,000 points of sales to which Gerdau sells its products, giving it comprehensive national coverage. Sales through its distribution network and to final industrial and construction consumers are made by Company employees and authorized sales representatives working on commission. This Business Operation has annual crude steel installed capacity of 9.1 million tonnes and 5.3 million tonnes of finished steel products.

North America Business Operation

The Company operates in North America through Gerdau Ameristeel. The North America Business Operation has annual manufacturing capacity of 9.9 million tonnes of finished steel products. It has a vertically integrated network of 19 steel units and one jointly controlled entity for the operation of a mini-mill, 22 scrap recycling facilities, 12 downstream operations (including three jointly controlled entities) and 48 fab shops. North America Business Operation’s products are generally sold to steel service centers and steel fabricators or directly to original equipment manufacturers for use in a variety of industries, including construction, automotive, mining, cellular and electrical transmission, metal construction fabrication and equipment fabrication. Most of the raw material feed stock for the mini-mill operations is recycled steel scrap.

This Business Operation operates mills and downstream. The mills manufacture and market a wide range of steel products, including steel reinforcement bars (rebar), merchant bars, structural shapes, beams, special sections and coiled wire rod. The mills also produce rebar, merchant bars, rod and special bar quality products used by the downstream and transfer these products at an arm’s length market price to the downstream. The downstream comprises secondary value-added steel businesses and consists of fabrication of rebars, railroad spikes, cold drawn products, super light beam processing, elevator guide rails, grinding balls, wire mesh and wire drawing.

The downstream strategy is to have production facilities located in close proximity to customers’ job sites so that quick delivery is provided to meet their reinforcing steel needs and construction schedules.

In general, sales of mill finished products to U.S. customers are centrally managed by the Tampa sales office while sales to Canadian customers are managed by the Whitby sales office. There is also a sales office in Selkirk, Manitoba for managing sales of special sections and one in Texas for managing sales of structural products. Metallurgical service representatives at the mills provide technical support to the sales group. Sales of the cold drawn and super light beam products are managed by sales representatives located at their respective facilities. Fabricated rebar and elevator guide rails are generally sold through a bidding process in which employees at the Company’s facilities work closely with customers to tailor product requirements, shipping schedules and prices.

At the North America Business Operation, despite the sharp drop-off in sales in 2009, a gradual recovery in demand was observed, as indicated by the 16.4% increase in sales volume in 2010 from 2009 and 13.7% increase in 2011 compared to 2010. The manufacturing industry was the main driver of the recovery in shipments. The Institute for Supply Management (ISM), the main indicator of industrial production in North America, remained above 50, indicating growth. The infrastructure and non-residential segments continue to present stable demand.

Since the end of 2000, Gerdau AZA has had a business unit known as AZAonLine, which services customers in Chile through the Internet. This was the first e-commerce initiative in the steel sector in Chile. Customers can track their orders on the Internet, together with product inventories and credit and payment status. They can also access their purchase records as well as generate quality certificates and place orders. Gerdau AZA sells its products to more than 150 clients, which are both distributors and end-users.

Colombia - Diaco was acquired in September 2005, which the Company believes to have a market share of 33.7% of the Colombian common long steel market. The Company believes it to be the largest producer of steel and rebar in Colombia, selling its products through distributors and clients (end-users) in civil construction, industry and others. Colombian units have annual installed capacity of 550,000 tonnes of crude steel and 650,000 tonnes of rolled products.

Peru - Siderperú was acquired in June of 2006 and is one of the main steel companies in Peru, with more than 50 years of experience in this business. The company sells its products to approximately 400 clients in the construction, manufacturing and mining sectors and has more than 160 distributors. Siderperú has annual installed capacity of 650,000 tonnes of crude steel and 960,000 tonnes of rolled products.

Mexico - Located in the Mexico City metropolitan area, Sidertul produces rebars and structural shapes, with its products primarily used in the domestic market. The Company sells its products to clients and distributors from the construction and manufacturing sectors. Sidertul sells products to around 200 clients and has annual installed capacity of 500,000 tonnes of crude steel and 430,000 tonnes of rolled products.

Special Steel Business Operation

The Special Steel Business Operation is composed of the operations in Brazil (Charqueadas, Pindamonhangaba, Mogi das Cruzes and Sorocaba), in the United States (MacSteel) and Spain (Corporación Sidenor). This operation, in partnership with its customers, produces engineering steel (SBQ), tool steel, stainless steel, rolling mill rolls, large forged and casted engineering pieces. In order to meet the continuous need for innovation, this operation is constantly developing new products, such as micro-alloyed steel for high-power and low-emissions diesel engines, clean steel for application in bearings, and steel with improved machining characteristics that allows higher machining speeds and lower tooling replacement, among others.

The Special Steel Business Operations recorded an increase of 6.0% in sales volume in 2011 from the prior year. The increase is mainly due to the economic recovery in the regions where we operate. The sales volume increase was stronger in the United States and Spain.

In Brazil, Gerdau special steel operations are located in Rio Grande do Sul (Charqueadas) and in São Paulo (Pindamonhangaba, Mogi das Cruzes and Sorocaba). The special steel units in Brazil have a combined annual capacity of 1.4 million tonnes of crude steel and 1.4 million tonnes of rolled products, which is sold in the domestic and export markets. The operation in Brazil has more than 400 customers located mainly in Brazil.

Gerdau maintains a presence in Europe through Corporación Sidenor, which sells special steel to the entire continent. Sidenor has more than 450 clients located mainly in Spain, France, Germany and Italy. Sidenor has an annual installed capacity of 1.0 million tonnes of crude steel and 1.1 million tones of rolled products. Sidenor also has four downstream operations located in Spain.

Gerdau maintains a presence in North America through MacSteel, the largest SBQ (Special Bar Quality) supplier in the United States. MacSteel operates three mini-mills, located in Jackson, Michigan; Monroe, Michigan; and

27

Fort Smith, Arkansas. The Company also operates six downstream operations located in Michigan (two), Ohio, Indiana (two) and Wisconsin. MacSteel has an annual installed capacity of 1.4 million tonnes of crude steel and 1.2 million tonnes of rolled products. MacSteel has more than 240 customers located mainly in the United States, Canada and Mexico.

There are commercial and operational synergies among these units in this business operation through centralized marketing and production strategies.

Exports

Gerdau International Trade (GIT) is responsible for trading all Gerdau’s business operations exports and imports in the world.

The current international economic scenario requires special care, especially in relation to financial guarantees for each business, always backed by letters of credit individually analyzed regarding their content and the issuing bank.

Brazil Business Operation, traditionally with more relevance in exports, had their availability reduced due to the momentum of the Brazilian domestic market. On the other hand, there was a significant increase in export volumes for the North America Business Operation.

In 2011 exports accounted for 28.3% of the Brazil Business Operation total sales, approximately the same as in 2010. Brazil Business Operation exports generated revenues of R$ 2,345.8 million in 2011, totaling 2.0 million tonnes (excluding intercompany sales), representing an increase of 3.8% over 2010.

The export strategy has allowed Gerdau to develop a client base that is more evenly distributed throughout the world, with exports going mainly to Asia, South America and North America.

The following table presents the Company’s consolidated exports by destination for the periods indicated:

Gerdau S.A. Consolidated |  | Year ended December 31, |
Exports by Destination |  | 2011 |  | 2010 |  | 2009 |
Total including shipments to subsidiaries (1,000 tonnes) |  | 3,832 |  | 3,022 |  | 1,858 |

Asia |  | 28 | % | 32 | % | 40 | %
Europe |  | 6 | % | 5 | % | 13 | %
Middle East |  | 2 | % | 4 | % | 0 | %

The North America Business Operation exported around 651,000 tonnes, accounting for 10.0% of the total sales in this operation in 2011. Latin America Business Operation exported about 54,000 tonnes, accounting for 2.0% of the total sales of this operation in 2011.

Products

The Company supplies its customers with a wide range of products from five major product lines:

Crude Steel (Billets, Blooms and Slabs)

Crude steel products (billets, blooms and slabs) have relatively low added value compared to other steel products. Billets are bars from square sections of long steel that serve as inputs for the production of wire rod, rebars and merchant bars. They are the main product of the Açominas mill. Blooms are used to manufacture products such as springs, forged parts, heavy structural shapes and seamless tubes. Slabs are used in the steel industry for the rolling of a broad range of flat rolled products. Slabs are mainly used to produce hot and cold rolled coils, heavy slabs and profiles.

28

Table of Contents

Crude steel products may be produced using either the continuous casting or conventional process. In the conventional process, liquid steel is poured into ingot moulds for rolling. The hot ingots are sent to the primary rolling mill to be heated in soaking pits and then are rolled to produce crude steel products (billets, blooms and slabs). Although this conventional process is not widely used in Brazil, it is still employed at the Company’s Açominas mill. The use of a conventional casting system may represent a competitive advantage since the Company believes it is one of the only companies manufacturing billets and blooms in Brazil, leading the Company to have captive customers for these products in Brazil and also outside the country.

Common Long Rolled Products

Common long rolled products represent a major portion of the Company’s production. The Company’s main long rolled products include rebars, merchant bars and profiles, which are used mainly by the construction and manufacturing industries.

Drawn Products

Drawn products include barbed and barbless fence wire, galvanized wire, fences, concrete reinforcing wire mesh, nails and clamps. These products are not exported and are usually sold to the manufacturing, construction and agricultural industries.

Special Steel Products

Special or high-alloy steel requires advanced manufacturing processes and normally includes some degree of customization. The Company produces special and stainless steel used in tools and machinery, chains, fasteners, railroad spikes and special coil steel at its Aços Villares and Piratini units in Brazil, at Corporación Sidenor units in Spain and at the MacSteel units in the United States.

In the United States, Gerdau Ameristeel produces special sections such as grader blades, smelter bars, light rails, super light I-beams, elevator guide rails and other products that are made on demand for the Company’s clients, which are mainly manufacturers.

It also supplies steel to its customers through its jointly controlled entity Kalyani Gerdau Steel Inc. located in India. It is a jointly controlled entity with the Kalyani Group in India in which Gerdau has an 80.6% stake in the jointly controlled entity.

Flat Products

The Company’s Açominas mill produces slabs, which are rolled into flat products such as hot and cold steel coils, heavy plates and profiles. In addition, the Company’s distribution subsidiary, Comercial Gerdau, resells flat steel products manufactured by other Brazilian steel producers, adding further value through additional processing at its four flat steel service centers.

Gerdau Ameristeel also supplies flat steel to its customers through its jointly controlled entity Gallatin located in Kentucky. Gallatin is a jointly controlled entity with ArcelorMittal, Canada, a leading flat steel producer, and has nominal installed capacity of 1.4 million tonnes of flat steel per year. Both partners in the jointly controlled entity have a 50.0% stake.

Production Process

In Brazil, the Company has a decentralized production process, using both mini-mills and integrated facilities. In general, the Company has used the mini-mill model to produce steel products outside of Brazil.

Non-Integrated Process (Mini-Mills)

The Company operates 50 mini-mills worldwide (excluding jointly controlled entities and associate companies). Mini-mills are equipped primarily with electric arc furnaces that can melt steel scrap and produce the steel product at the required specifications. After loading the furnace with a preset mixture of raw material (i.e., steel scrap, pig iron and sponge iron), electric power is applied in accordance with a computer controlled melting profile. The Company’s mini-mill production process generally consists of the following steps: obtaining raw material, melting, casting, rolling and drawing. The basic difference between this process and the integrated mill production process described below is in the first processing phase, i.e., the steelmaking process. Mini-mills are smaller plants than integrated facilities and the Company believes they provide certain advantages over integrated mills, including:

29

Table of Contents

· lower capital costs,

· lower operational risks due to the low concentration of capital and installed capacity in a single production plant,

· proximity of production facilities to raw-material sources,

· proximity to local markets and easier adjustment of production levels, and

· more effective managerial structure due to the relative simplicity of the production process.

Integrated Process

The Company operates 4 integrated mills, of which 3 are located in Brazil and 1 in Peru. The Açominas mill is the largest integrated facility the Company operates. Although it produces steel using a blast furnace, this mill has some of the advantages of a mini-mill since it is located very close to its main suppliers and the ports from which the Company exports most of its production.

The Company’s steelmaking process in integrated facilities consists of four basic processes: raw material preparation, pig-iron production, steel production and production of crude steel (billets, blooms and slabs). In the primary stage of iron making, sinter (a mixture of iron ore and limestone), coke and other raw materials are consumed in the blast furnace to produce pig iron. Coke acts as both a fuel and a reducing agent in this process. The Company’s blast furnaces have installed capacity of 5.9 million tonnes of liquid pig iron per year.

The pig iron produced by the blast furnace is transported by rail to the desulphurization unit to reduce the sulfur content in the steel. After the desulphurization process, the low-sulfur pig-iron is transformed into steel through LD-type oxygen converters. The LD steelmaking process utilizes molten pig iron to produce steel by blowing oxygen over the metallic charge inside the converters. The process does not require any external source of energy, which is fully supplied by the chemical reactions that occur between the oxygen and the molten pig iron impurities. The LD steelmaking process is presently the most widely used in the world.

Some mills further refine the LD converters’ output with ladle furnaces. Liquid steel is then poured into ingot molds and allowed to solidify into ingots. The molds are stripped away and the ingots are transported by rail to the soaking pits, where they are heated to a uniform rolling temperature. The heated ingots are rolled in the primary rolling mill to produce slabs and blooms, some of which are rolled in the secondary rolling mills to produce blooms and billets. At this point in the process, the Company either sells a portion of the product to other manufacturers where the rolling process must take place in order to produce steel ready for final use, or the Company performs the rolling process itself, transforming the product into heavy structural shapes or wire rods.

Logistics

The Company sells its products through independent distributors, direct sales from the mills and its retail network called Comercial Gerdau.

Transportation costs are an important component of most steel mill businesses and represent a significant factor in maintaining competitive prices in the export market. The Company’s mills are strategically located in various different geographic regions. The Company believes that the proximity of its mills to raw material sources and important consumer markets gives it a competitive advantage in serving customers and obtaining raw materials at competitive costs. This represents an important competitive advantage in inbound and outbound logistics.

To reduce logistic costs, Gerdau also uses different types of transportation modes (road, rail, sea and cabotage) to receive raw materials, and to deliver products to its customers or ports of destination. Accordingly, Gerdau has developed long-term relationships with logistic companies specialized in delivering raw materials and steel products.

In 1996 Gerdau acquired an interest in MRS Logística, one of the most important rail companies in Brazil, which operates connecting the states of São Paulo, Rio de Janeiro and Minas Gerais, which are Brazil’s main economic centers, and also reaches the main ports of the country in this region. These shares provide the guarantee of using this mode to transport raw materials (scrap and pig iron) as well as final products. In North America, the Company owns a large number of rail cars for the same purpose.

Gerdau uses around 15 ports to deliver products from the entire Brazilian coastline. The majority of exports are shipped from Praia Mole Private Steel Terminal in Vitoria, Espírito Santo. Furthermore, this is Brazil’s most efficient and productive seaport for handling steel products, with more than 20 years of expertise in this business.

Gerdau also owns specialized terminals for iron ore deliveries that supply its steel units in the state of Bahia, Brazil and in Peru. Additionally, Gerdau is currently in progress with a project and construction of a new export terminal for coal in Colombia.

Competition

The steel market is divided into manufacturers of long steel products, flat steel products and special steel.

The Company operates in the long steel market, which is the most important market for Gerdau, by supplying to the following customer segments: (i) construction, to which it supplies rebars, merchant bars, nails and meshes; (ii) manufacturing, to which it supplies products for machinery, agricultural equipment, tools and other industrial products; and (iii) other markets, to which it supplies wires and posts for agricultural installations and reforestation projects. In North America, the Company also supplies customers with special sections, including elevator guide rails and super light beams. The Company also provides its customers with higher value-added products at rebar fabrication facilities.

The Company operates in the flat steel market through its Açominas mill that produces slabs, which are used to roll flat products such as hot and cold rolled steel coils, heavy plates and profiles. In addition, the Company’s distribution subsidiary, Comercial Gerdau, resells flat steel products manufactured by other Brazilian steel producers, adding further value through additional processing at its four flat steel service centers. Gerdau Ameristeel also supplies flat steel to its customers through its jointly controlled entity Gallatin. Gallatin is a jointly controlled entity with ArcelorMittal, a leading flat steel producer, and has nominal installed capacity of 1.4 million tonnes of flat steel per year.

The Company produces special and stainless steel used in tools and machinery, chains, fasteners, railroad spikes, special coil steel, grader blades, smelter bars, light rails, super light I-beams, elevator guide rails and other products that are made on demand for the Company’s customers at its special steel units in Brazil, United States, Spain and through its jointly controlled company in India.

Competitive Position — Brazil

The Brazilian steel market is very competitive. In the year ended December 31, 2011, the Company was the largest Brazilian long steel producer and the second largest crude steel producer, according to the Brazilian Steel Institute (IABr - Instituto Aço Brasil). Meanwhile, ArcelorMittal Brasil was the second largest long steel producer and the first largest crude steel producer in Brazil during 2011.

The table below presents the Company’s main competitors and market share in Brazil’s crude steel market:

World common long rolled steel demand is met principally by steel mini-mills and, to a much lesser extent, by integrated steel producers. In the Brazilian market, no single company competes against the Company across its entire product range. The Company faced some competition from long steel products imports, mainly coming from Turkey throughout 2010, and with less extension in 2011. The Company believes that the diversification of its products, the solution developed by its fab shops units and the decentralization of its business provide a competitive edge over its major competitors.

In the domestic market, Gerdau is almost an exclusive supplier of blooms and billets to well-defined and loyal customers that have been purchasing from it regularly for over 15 years. Intense competition exists between the Company and ArcelorMittal in the slab and wire rod markets.

Competitive Position — Outside Brazil

In the international market, the Company, in its export markets, faces strong competition in the commercial quality products line from Eastern Europe (CIS). The main competitors in the high quality products segment are Europeans and, to a lesser extent, the Japanese. The Company is a strong player due to its vast experience and the high quality of its services and products. Gerdau has a highly diversified list of traditional customers located all over the world.

Outside Brazil, notably in North America, the Company’s subsidiary Gerdau Ameristeel has increased its market share through acquisitions. Gerdau Ameristeel is the second largest mini-mill steel producer in North America and has progressively increased its share in the North American market, with annual nominal capacity of 9.9 million tonnes of crude steel and 9.2 million tonnes of rolled products.

Gerdau Ameristeel’s geographic market encompasses primarily the United States and Canada. Gerdau Ameristeel faces substantial competition in the sale of each of its products from numerous competitors in its markets. Rebar, merchant bars and structural shapes are commodity steel products for which pricing is the primary competitive factor. Due to the high cost of freight relative to the value of steel products, competition from non-regional producers is somewhat limited. Proximity of product inventories to customers, combined with competitive freight costs and low-cost manufacturing processes, are key to maintaining margins on rebar and merchant bar products. Rebar deliveries are generally concentrated within a 350-mile radius of the mini-mills and merchant bar deliveries are generally concentrated within a 500-mile radius. Some products produced by the Selkirk, Midlothian, Jacksonville, Jackson, Cartersville and Petersburg mini-mills are shipped greater distances, including overseas. Except in unusual circumstances, the customer’s delivery expenses are limited to freight charges from the nearest competitive mill, and the supplier absorbs any incremental freight charges.

The Company’s principal competitors include Commercial Metals Company, Nucor Corporation, Steel Dynamics Inc., and ArcelorMittal Inc. Gallatin Steel competes with numerous other integrated and mini-mill steel producers.

Despite the commodity characteristics of the rebar, merchant bar and structural markets, Gerdau Ameristeel believes it distinguishes itself from many of its competitors due to the Company’s large product range, product quality, consistent delivery performance, capacity to service large orders and ability to fill most orders quickly from inventory. The Company believes it produces one of the largest ranges of bar products and shapes. The Company’s product diversity is an important competitive advantage in a market where many customers are looking to fulfill their requirements from a few key suppliers.

In Latin America, each country has a specific competitive position that depends on conditions in their respective markets. Most compete domestically and face significant competition from imports. More than 75% of shipments from Gerdau’s Latin American Operation originate from Chile, Peru, Colombia and Mexico. In Chile, the main barriers faced by Gerdau AZA sales are freight and transportation costs and the availability of imports. The Company estimates the share of the domestic long steel market held by Gerdau AZA at about 30% and their products are oriented to satisfy the constructions, mechanic, agriculture and mining market. It also believes that Diaco has a 30% stake in the Colombian steel market and that Siderperú has market share of approximately 36% in the long products segment in Peru.

Spain special steel operation holds approximately 10% of the special steel market in the European Union; USA special steel operation has roughly 20% share in the SBQ market; and in Brazil, Gerdau’s special steel units are combined the biggest player in that market.

Business Cyclicality and Seasonality

The steel industry is highly cyclical worldwide. Consequently, the Company is exposed to substantial swings in the demand for steel products which in turn causes volatility in the prices of most of its products. In addition, since the Brazilian steel industry produces substantially more steel than the domestic economy is able to consume, the sector is dependent on export markets. The demand for steel products and hence the financial condition and operating results of companies in the steel industry, including the Company itself, are generally affected by macroeconomic fluctuations in the world economy and the domestic economies of steel-producing countries, including general trends in the manufacturing, construction and automotive sectors. Since 2003, demand for steel products from developing countries (particularly China) and overall world economic growth have contributed to historically high levels in the prices of the Company’s steel products. However, these relatively high prices may not last, especially due to expansion in world installed capacity or a new level of demand. In the second half of 2008, and especially in the beginning of 2009, the U.S. and European economies showed strong signs of slow down, in turn affecting many other countries. Since the end of 2009 and throughout 2010 and 2011, the world steel demand and prices have been improving if compared to the beginning of 2009 and the Company believes that this trend will continue throughout 2012. A material decrease in demand for steel or exports by countries not able to consume their production, as happened in 2008, could have a significant adverse effect on the Company’s operations and prospects.

Table of Contents

In the Company’s Brazilian and Latin American operations, shipments in the second and third quarters of the year tend to be stronger than in the first and fourth quarters, given the reduction in construction activity. In the Company’s North American operations, demand is influenced by winter conditions, when consumption of electricity and other energy sources (i.e., natural gas) for heating increases and may be exacerbated by adverse weather conditions, contributing to increased costs and decreased construction activity, and in turn leading to lower sales. In the Company’s Special Steel Operations, particularly in Spain, the third quarter is traditionally marked by collective vacations that reduce operations in the quarter to only two months.

Information on the Extent of the Company’s Dependence

In the case of a power outage, there are no alternative supply options available at most Gerdau mills due to the high volume and tension required for the operation of these plants. Some Gerdau small plants may choose, as an alternative, to use generators to compensate for the energy shortage. Moreover, the Açominas mill generates 70% of its power needs internally using gases generated in the steel-making process.

In case of a lack of natural gas, the equipment could be adjusted to use diesel and LPG.

The distribution of electric power and natural gas is a regulated monopoly in most countries, which leads the distributor to be the only supplier in each geographic region. In some countries, regulations allow for a choice of electrical power or natural gas commodity supplier, allowing Gerdau to diversify its supply agreement portfolio.

Production Inputs

Gerdau’s production processes are based mainly on the mini-mill concept, with mills equipped with electric arc furnaces that can melt ferrous scrap and produce steel products at the required specifications. The main raw material used at these mills is ferrous scrap, which at some plants is blended with pig iron. The component proportions of this mixture may change in accordance with prices and availability in order to optimize raw material costs. Iron, iron ore (used in blast furnaces and in one Direct Reduction Iron - DRI plant) and ferroalloys are also important.

Although international ferrous scrap prices are determined by the U.S. domestic market (since the United States is the largest scrap exporter), the price of ferrous scrap in Brazil varies from region to region and is influenced by demand and transportation costs. Gerdau is the largest consumer of ferrous scrap in Brazil.

Brazil and Special Steel Business Operations - The Company’s Brazilian mills use scrap and pig iron purchased from local suppliers. Due to the nature of the raw materials used in its processes, Gerdau has medium and long-term supply contracts with scrap generators and short-term contracts with some suppliers for its mini-mills in Brazil, acquiring scrap as necessary for the mills’ needs. Scrap for the Brazilian Operation is priced in Brazilian reais, thus input prices are not directly affected by currency fluctuations.

In the Açominas mill the main raw materials of this unit include: (i) coal imported from Canada, Australia and the United States, anthracite from Vietnam and the Ukraine and coke petroleum purchased from Petrobras; (ii) ferroalloys, of which 90.0% is purchased in the domestic market; and (iii) iron ore, which is partially produced from its own mines and partially supplied by large, medium, and small sized mining companies, most of them strategically located close to the plant. These three items accounted for about 45% of the total production costs of Açominas mill in 2011. Due to its size, the Açominas mill utilizes long-term contracts to guarantee raw material supplies.

North America Business Operation - The main metallic input used by the Company’s mills in the United States is ferrous scrap. When ferrous scrap prices exceed acceptable levels, as occurred in 2004, the mills seek to modify input sources accordingly. Gerdau Ameristeel has consistently obtained adequate supplies of raw materials and is not dependent on a smaller number of suppliers.

Latin America Business Operation - The main metallic input used by the Company’s mills in Latin America is ferrous scrap. The Latin American Operation is exposed to market fluctuations, varying its prices according to each local market.

Ferrous Scrap

There are two broad categories of ferrous scrap: (i) obsolete scrap which is steel from various sources, ranging from tin cans to car bodies and white goods; and (ii) industrial scrap, which is essentially factory steel bushings and flashings, steel turnings and even scrap generated by the Company’s production processes themselves. In Brazil the use of scrap in electric arc furnaces varies between obsolete scrap and industrial scrap. The Special Steel plants use mainly industrial scrap.

33

Table of Contents

In 2011 Gerdau utilized more than 15 million tonnes of scrap, accounting for significant gains through increasingly competitive operating costs.

Brazil and Special Business Operations - The price of scrap in Brazil varies by region, depending upon local supply and demand, and transportation costs. The Southeast region is the most industrialized in the country, generating the highest volume of scrap. Due to the high concentration of players in this region, the competition is more intense.

The Company also has five shredders, including a mega-shredder at Gerdau Cosigua in Rio de Janeiro capable of processing shredded scrap in volumes that exceed 200 car bodies per hour.

At Gerdau Special Steel Europe, industrial scrap is the main type of raw material used in the Spanish operation.

North America Business Operation - Ferrous scrap is the primary raw material to this Business Operation. It is a commodity whose availability varies in accordance with the level of economic activity, seasonality, export levels, and price fluctuations. Twelve of Gerdau North America Business Operation mini-mills have on-site dedicated scrap processing facilities, including shredder operations that supply a significant portion of their scrap requirements. Given the fact that not all of the scrap it consumes is sourced from its own scrap yards, it buys residual requirements in the market either directly or through dealers that source and prepares scrap.

All of production facilities in North America are mini-mills, in which operating results are closely linked to the cost of ferrous scrap and scrap substitutes, the primary input of mini-mills. Ferrous scrap prices are relatively higher during winter months due to the impact of weather on collecting and supplying efforts. More than half of all steel products in North America are currently made in electric arc furnaces using ferrous scrap. Prices for ferrous scrap are subject to market forces largely beyond the Company’s control, which include demand from U.S. and international steel producers, freight costs and speculation.

Latin America Business Operation - The price of scrap in the Latin America varies in accordance with demand, transportation costs and region.

Pig Iron and Sponge Iron

Brazil Business Operation - Brazil is an exporter of pig iron. Most Brazilian pig iron is produced in the state of Minas Gerais by a large number of small producers. Pig iron is a natural substitute for scrap, and in Brazil it is an important component of the metal mix used to make steel in the mills. In Brazil, the price of pig iron is related to internal and external demand and to the cost of charcoal, the most volatile cost item in pig iron production.

The Company does not have any Brazilian contracts for the supply of pig iron, negotiating amounts and delivery conditions directly with suppliers. The price of pig iron may fluctuate in line with its international market price, given that a large portion of production in Brazil is exported.

North America Business Operation - Scrap availability is a major factor in Gerdau North America Business Operation. Sponge iron and pig iron can substitute a limited portion of the ferrous scrap used in electric arc furnace steel production. Gerdau Ameristeel does not utilize significant quantities of scrap substitutes in its mini-mills except for pig iron used for its chemical properties at the Beaumont facility, and to produce some special sections.

Iron Ore

Iron ore is the main input to produce steel at Gerdau’s plants in Ouro Branco, Barão de Cocais, Contagem, Divinópolis, and Sete Lagoas located in Minas Gerais State, southeastern Brazil.

Iron ore is purchased in its natural form as lump ore, pellet feed or sinter feed, or agglomerated as pellets. Iron ore fines are agglomerated in the sinter plant and then loaded into the blast furnace, which produces pig iron, which is refined and turned into steel. Lump ore and pellets are directly loaded into the blast furnace to increase productivity. To produce 1.0 ton of pig iron requires about 1.6 tonnes of iron ore.

Iron ore consumption in Gerdau mills in Brazil amounted to 7.1 million tonnes in 2011, partially supplied by mining companies adjacent to the steel plants and partially supplied by Gerdau’s mines.

Other Inputs

In addition to scrap, pig iron, sponge iron and iron ore, Gerdau’s operations use other inputs to produce steel such as ferroalloys, electrodes, furnace refracting materials, oxygen, nitrogen and other industrial gases and limestone,

34

Table of Contents

albeit in smaller amounts. All of these inputs are readily available in Brazil. Additional inputs associated with the production of pig iron are charcoal, which is used in blast furnace mills, and natural gas, which is used at the DRI unit.

Açominas mill’s important raw materials and inputs also include solid fuels, comprising the Metallurgical Coal, used in the production of coke for blast furnace and also for the blast furnace pulverized injecting, this last one providing increase in productivity and consequently reduction in the final cost of pig iron. Besides the metallurgical coal, we use the anthracite, solid fuel used in the production of sinter. The gas resulting from the production of coke and pig iron are reused, inclusive for generating electricity to power the plant.

Gerdau has a metallurgical coke producer with annual capacity of 400,000 tonnes per year, and coking coal resources estimated at 20.0 million tonnes.

The North American operations also use additional inputs. Various domestic and foreign companies supply other important raw materials or operating supplies required for the business, including refractory materials, ferroalloys and carbon electrodes that are readily available in the open market. Gerdau North America Business Operation has obtained adequate quantities of these raw materials and supplies at competitive market prices. The Company is not dependent on any one supplier as a source for any particular material and believes there are adequate alternative suppliers available in the marketplace if the need to replace an existing one arises.

Energy Requirements

Steel production is a process that consumes large amounts of electricity, especially in electric arc mills. Electricity represents an important cost in the production process, along with natural gas, which is used in furnaces to re-heat billets in rolled steel production.

Dona Francisca Energética S.A. (DFESA) operates a hydroelectric power plant with nominal capacity of 125 MW located in Agudo, Rio Grande do Sul State (Brazil). Its corporate purpose is to operate, maintain and maximize use of the energy potential of the Dona Francisca Hydroelectric Plant. DFESA participates in a consortium (Consórcio Dona Francisca) with the state power utility Companhia Estadual de Energia Elétrica (CEEE). The shareholders of DFESA are Gerdau S.A. (51.8%), COPEL Participações S.A (23.0%), Celesc (23.0%), and Desenvix (2.2%).

Caçu and Barra dos Coqueiros hydroelectric power plants, located in the state of Goiás (Brazil), with total installed capacity of 155MW and started its operations in 2010, with all power made available to the units located in Brazil’s Southeast.

Gerdau also holds the concession to operate the São João — Cachoeirinha Hydroelectric Plant Complex located in Paraná state. The complex will have total installed capacity of 105 MW. The start of construction is currently awaiting the granting of the environmental licenses.

The terms of the aforementioned generation concession agreements are for 35 years as of the signature of the agreement. As such: UHE Dona Francisca expires in 2033 and UHEs Caçu and Barra dos Coqueiros and UHEs São João - Cachoeirinha expire in 2037.

The Company is currently analyzing power generation alternatives in all countries where it operates.

In Brazil, the Company’s units hold long-term contracts with electricity suppliers and do not depend on a single contract. Energy is currently supplied to the Company’s industrial units under two types of contracts:

· Contracts in the Regulated Contractual Environment in which the Company is a “Captive Consumer” are used at the following units: Piratini, Vila Guaíra, Água Funda, Usiba, Açonorte and Sorocaba. These involve state-owned companies or holders of government concessions. In these contracts, prices are defined by the National Electric Power Agency (ANEEL).

· Contracts in the Free Market Environment in which Gerdau is a “Free Consumer” are used at the following units: São Paulo, Cosigua, Cearense, Açominas, Divinópolis, Barão de Cocais, Riograndense, Araucária, São José dos Campos, Pindamonhangaba and Mogi das Cruzes. These units have power purchase agreements contracted directly with power generation companies and/or energy traders, with prices defined and adjusted according to rules predetermined by the parties. The transmission and distribution rates are regulated by ANEEL and revised annually. Açominas mill generates approximately 70.0% of its energy needs internally, using gases generated by the steelmaking process. This keeps its exposure to the energy market significantly lower than in the case of mini-mills.

The supply of natural gas to all Brazilian units is regulated and performed under long-term contracts. The Barão de Cocais and Divinópolis units do not have access to natural gas supplies.

35

Table of Contents

In Spain the new energy contract will start in January 2012, remaining until December 2012. For the first quarter the energy will be acquired for fixed values. For other months the price of energy is related to the spot market, with the option of fixing the price by Gerdau. The natural gas contract also lasts until December 2012.

In North America, there are two types of energy markets: regulated and deregulated. In the regulated market, agreements are established with local electric power concession holds and the rates are determined for each region. In the deregulated market, the price of power can change every 5 minutes (spot price) to reflect the actual cost of electricity generation. Although the deregulation of both the natural gas and wholesale electricity markets may create opportunities to reduce costs as a result of market competition, the prices of both these forms of energy have recently become more volatile and may remain so.

In Colombia, the electricity agreements were renewed in 2009 and are valid until 2014. The natural gas agreements were renewed in 2011 and are valid until 2013.

In Chile, Gerdau AZA renegotiated its electricity agreement until 2014. It was signed a new agreement for the supply of natural gas from the second half of 2009 based on imports of liquefied natural gas (LNG) to a lower prices compared to alternative fuels.

In Uruguay, electricity is purchased under long-term agreements. Natural gas is purchased from Montevideo Gas and the prices are set by the Argentinean export tariffs.

In Peru electricity is purchased under a long-term agreement. The plant has no access to natural gas supply due to its location, although since late 2011 has been consuming CNG (Compressed Natural Gas) for part of their needs.

Argentina utilizes natural gas (LPG as a substitute) and Uruguay also uses natural gas (Fuel Oil as substitute). In 2008, Gerdau Sipar signed a contract with Petrobrás to supply the new plant´s power requirements up to May 2010. In view of the postponement of this project, this contract was renegotiated. The natural gas supply contract expires in May 2012.

A new power purchase agreement in the Dominican Republic was closed in 2009 with a 5-year term. Beginning in 2011, the unit will receive LNG (liquefied natural gas) thru ships and trucks.

In Mexico, electricity is purchased under a long-term agreement. In these agreements, the demand and consumption are negotiated between the parties, and the tariffs are set by the state company CFE (Companía Federal de Electricidad). The natural gas agreements have the duration of 5 years.

Technology and Quality Management

All Gerdau mills have excellent quality management supported by a wide array of quality control tools. Product development projects are headed by specialists who use quality tools such as “Six Sigma”, a set of statistical methods for improving the assessment of process variables, as well as “Quality Function Deployment”, a methodology through which technicians can identify the full range of customer requirements.

Given this level of quality management, 45 mills are ISO 9001 or ISO TS 16949 certified. In general, production , technical services and quality teams are responsible for developing new products to meet customer and market needs.

The Company uses a quality management system developed in house that applies tests for product design, manufacturing processes and final-product specifications. A specially trained team and modern technologies also exist to assure the Company’s high standards of quality. The Company’s technical specialists make planned visits, some may be randomly selected and some are scheduled visits, to its customers to check on the quality of the products delivered by the Company in order to guarantee the final user satisfaction for products purchased indirectly.

Knowledge Management Portal is used to share information among all steel mills seeking performance improvements and leverage of process knowledge supported by Communities of Practice and technical specialists.

Due to the specialized nature of its business, the Company’s special steel mills are constantly investing in technological upgrading and in research and development. These mills are active in the automotive segment and maintain a technology department responsible for new products and the optimization of existing processes.

International machinery manufacturers and steel technology companies supply most of the sophisticated production equipment the Company uses. These suppliers generally sign technology transfer agreements with the purchaser and provide extensive technical support and staff training for the installation and commissioning of the

36

Table of Contents

equipment. The Company has technology transfer agreements with Nippon Steel, Kyoei Steel, Thyssen, Daido Steel and BSW.

As is common with mini-mill steelmakers, the Company usually acquires technology in the market rather than developing new technology through intensive research and development, since steelmaking technology is readily available for purchase.

The Company is not dependent on patents or licenses or new manufacturing processes that are material to its business. See item “Information on the Extent of the Company’s Dependence” for further details.

Sales Terms and Credit Policy

The Company’s Brazilian sales are usually made on a 21/28-day settlement CIF (Cost, Insurance and Freight) basis. Comercial Gerdau, the retail arm of Gerdau in Brazil, sells on a 29-day settlement basis, mainly CIF. Brazilian customers are subject to a credit approval process. The concession of credit limits is controlled by a corporate-level system (SAP R/3) that can be accessed by all sales channels. The credit and collection department is responsible for evaluating, determining and monitoring credit in accordance with the credit limit policy. This policy includes the active participation of staff from the various sales channels. At Comercial Gerdau, in particular, the criteria for retail sales also include practices such as the use of credit card services. Açominas mill exports are guaranteed via letters of credit and/or pre-payment before the product is shipped. Exports to Gerdau’s subsidiaries may be sold on credit at market interest rates.

Gerdau North American credit terms to customers are generally based on customary market conditions and practices. The Company´s North American business is seasonal, with orders in the second and third quarters tending to be stronger than those in the first and fourth quarters, primarily due to weather-related slowdowns in the construction industry.

The Company´s Special Steel Operation in Spain has a Risk Committee that is responsible for analyzing customer credit. The United States and Brazil Special Steel Operations have their own credit departments for costumer’s credit analyses.

As a result of these policies, the Company’s provision for doubtful accounts has been at low levels. On December 31, 2011, provision for doubtful accounts was 1.7% based on gross account receivables as per Note 5 to the Consolidated Financial Statements, on December 31, 2010 was 2.1% and on December 31, 2009 this provision was 3.1% of gross account receivables. The 2009 level was an exception due to the international economic crisis during the year. Gerdau has improved its credit approval controls and enhanced the reliability of its sales process through the use of risk indicators and internal controls.

Insurance

The Company maintains insurance coverage in amounts that it believes suitable to cover the main risks of its operating activities. The Company has hired insurance for its Açominas mill against operating losses, which covers amounts up to approximately US$ 4.6 billion (R$ 7,3 billion as of April 30, 2011), including material damage to installations (US$ 3.3 billion) and losses of gross revenues (US$ 1.3 billion), such as halts in production due to business interruptions caused by accidents for a period up to twelve months. The Company’s current insurance policy relating to the Açominas mill remains effective until April 30, 2012. The Company’s mini-mills are covered against operational losses under its policy.

Trade Investigations and Government Protectionism

Over the past several years, exports of steel products from various companies and countries, including Brazil, have been subject to antidumping, countervailing duties and other trade-related investigations in importing countries. Most of these investigations resulted in duties limiting the investigated companies’ ability to access such import markets. Until now, however, these investigations have not had a significant impact on the Company’s export volumes.

Mine Operating License

In Brazil, the Company’s mining operations are subject to government concessions, and its mining activities are subject to the limitations imposed by Brazil’s Federal Constitution and Mining Code and the laws, rules and regulations enacted pertaining to mining activities. Under the concession contracts, the Company was granted permission to commercially operate the mines located at Miguel Burnier, Várzea do Lopes, Dom Bosco and Gongo Soco in the state of Minas Gerais Brazil, for as long as the reserves last. Brazil’s Mining Code and Federal Constitution impose on companies that conduct mining activities, such as us, requirements concerning, among other things, the manner in which

37

Table of Contents

mineral deposits are used, worker health and safety, environmental protection and restoration, the prevention of pollution and the health and safety of the local communities where the mines are located.

In Colombia there are some mining operations, which concessions are governed by the Government and ruled by regulations contained in the Mining Code (Law 685 of 2001 and Law 1382 of 2010). Under the concession rights given to the Company, exploration and exploitation projects of coking coal can be developed. The mines are located at Tausa, Cundinamarca; Cucunubá, Cundinamarca; Samacá and Ráquira, Boyacá; and Cúcuta, north of Santander. The period of the concessions is 30 years and it can be extended for an additional 30 years. Environmental requirements are also part of the rules that have to be fulfilled in order to develop the projects, in addition to issues relating the payment of royalties and the priority security of the personnel (mining).

Material Effects of Government Regulation

In addition to the government regulations that apply to its industry in general, the Company is not subject to any specific regulations that materially and adversely affect its business.

C. ORGANIZATIONAL STRUCTURE

The Company’s operational structure (including its main operating subsidiaries engaged in steel production) was as follows on December 31, 2011:

While electric arc furnace (EAF) mills produce crude steel from raw materials such as steel scrap or pig iron, a mill with a blast furnace or direct reduction iron (DRI) produces pig iron or sponge iron for use in the production of crude steel, with iron ore and natural gas being the main raw materials.

Mining Assets

Although the Company is primarily focused on the steel business, it owns mineral assets in order to have its own sources of minerals by acquiring land and mining rights. The iron ore mines are located in Miguel Burnier, Várzea do Lopes, Dom Bosco and Gongo Soco near the Açominas mill in the state of Minas Gerais, Brazil. The coal mines are located in Tausa, Cucunubá, Samacá, Ráquira and Cúcuta, Colombia. The use of these mineral resources as an input for our integrated mill (Açominas) should contribute to the long term competitiveness of this unit.

Investment Programs

In fiscal year 2011, capital expenditure on fixed assets was R$ 1,961.4 million. Of this total, 70.3% was allocated to Brazil Business Operation units and the remaining 29.7% was allocated to the other business operations.

Brazil Business Operation — a total of R$ 1,378.6 million was invested in this operation for capital expenditure. A major part of this investment was for the installation of heavy plates and hot-rolled coil rolling mills at the Açominas mill. The Company also invested for the development and installation of new downstream units. Moreover, in the beginning of 2011, the Company completed the expansion of the structural profile rolling mill at the Açominas mill.

North America Business Operation — this business operation spent R$ 171.1 million, for capital expenditure on fixed assets equally distributed throughout the units which compose this business operation.

Latin America Business Operation — in 2011, the Latin American units spent R$ 200.3 million, for capital expenditure on fixed assets distributed among the countries in which the units from this business operation are located, with material portion destined to the development of the port facility in Colombia.

Special Steel Business Operation — the special steel units spent R$ 211.4 million in 2011, for capital expenditure on maintenance and technological upgrade equally distributed throughout the units which compose this business operation.

The investments in fixed assets planned for the period from 2012 to 2016 are estimated at R$ 10.3 billion, and include both strategic and maintenance investments (see table below).

The respective permits and licenses require the satisfaction of various performance standards, which are monitored by regulatory authorities. The Company employs a staff of experts to manage all phases of its environmental programs and uses outside experts where needed. The Company works to assure that its operations maintain compliance in all material respects with the applicable environmental laws, regulations, permits and licenses currently in effect. When Gerdau acquires new plants, it conducts an assessment of potential environmental issues and prepares a work plan in compliance with the local authorities.

The steel production process generates air and water emissions, as well as solid wastes, which may pose environmental hazards. The principal potential hazardous waste generated by current and past operations is electric arc furnace dust, a byproduct from the production of steel in electric arc furnaces. Gerdau installs baghouse filter systems in all facilities where its produces steel, which assures high levels of efficiency in terms of dust filtration and retention. The costs with collecting and disposing of electric arc furnace dust are expensed as operating costs when incurred. Environmental legislation and regulations at both the federal and state levels concerning electric arc furnace dust in any jurisdiction is subject to potential changes, which could increase the cost of compliance. The Company believes the electric arc furnace dust generated by its current production processes is being collected, handled and disposed of in a manner that in all material respects meets all current federal, state and local environmental regulations.

In most countries, both federal and state governments have the power to enact environmental protection laws and issue regulations under such laws. In addition to those rules, the Company is also subject to municipal environmental laws and regulations. Under such laws, individuals or legal entities whose conduct or activities cause harm to the environment are usually subject to criminal and administrative sanctions, as well as any costs to repair the actual damages resulting from such harm. Individuals or legal entities that commit environmental crimes usually are subject to penalties and sanctions that for individuals range from fines to imprisonment, and for legal entities include suspending or interrupting operations and prohibiting entering into any contracts with government agencies.

Government environmental protection agencies usually may also impose administrative sanctions on individuals and entities that fail to comply with environmental laws and regulations that include:

· fines;

· partial or total suspension of operations;

· obligations to provide compensation for recovery works and environmental projects;

· forfeiture of or restrictions on tax incentives and benefits;

· closing of establishments or enterprises; and

· forfeiture or suspension of participation in credit lines with official credit agencies.

In 2006, the subsidiaries in Brazil evaluated seven of their operational sites regarding potential environmental impacts caused by past operations. The Company concluded that its past operations may have caused environmental damage, mainly due to the use and disposal of hazardous substances, and that it may be required in the future by authorities to remedy these environmental damages. Based on assumptions of the extent of the potential damage caused and on the time of the remedial process, the Company has made estimates to determine the amounts involved in data collection, analysis and determination of the actual environmental impact in the areas potentially impacted by its operations. “These estimates amount to US$ 25.9 million and were recorded under “Environmental Liabilities”. Those amounts may vary in the future, depending on the development of research and the conclusion of the environmental impact studies. In December 31, 2011 the updated present value of the total remaining amount of Brazilian Environment Liabilities was estimated at R$ 20.1 million. Some of these areas have already been recovered and some areas are still being evaluated.

Gerdau Ameristeel and Macsteel estimated clean-up costs based on a review of the anticipated remedial activities to be undertaken at each of their respective known contaminated sites. Although the ultimate costs associated with such remedies are not precisely known, the Company has estimated the present value of the total remaining costs as of December 31, 2011 at approximately R$ 68.4 million, with these costs recorded as a liability in its financial statements in Note 20 — Environmental Liabilities.

Gerdau has industrial facilities holding ISO 14001 certification in many countries, of which 17 units are in Brazil; 1 in Chile; 3 in Colombia; 1 in Uruguay, 1 in Argentina; 19 in North America and 5 in Spain.

Brazilian Environmental Legislation

The Company’s activities are subject to wide-sweeping Brazilian environmental legislation at the federal, state and municipal levels that govern, among other aspects, the dumping of effluents, atmospheric emissions and the handling and final disposal of dangerous waste, as well as the obligation to obtain operating licenses for the installation and operation of potentially polluting activities.

Brazilian environmental legislation provides for the imposition of criminal and administrative penalties on natural persons and legal entities that commit environmental crimes or infractions, as well as for the obligation to repair the environmental damage caused. Although the Company has never suffered any environmental penalties that could have a relevant impact on its business, potential environmental crimes or infractions could subject the Company to penalties that include:

· fines that at the administrative level could reach as high as R$50 million, depending on the violator’s economic capacity and past record, as well as the severity of the facts and prior history, with the amounts potentially doubled or tripled in the case of repeat offenders;

· suspension of or interference in the activities of the respective enterprise; and

· loss of benefits, such as the suspension of government financing and the inability to qualify for public bidding processes and tax breaks.

Table of Contents

In addition, strict liability is applicable to environmental crimes for both natural persons and legal entities. Environmental legislation also provides for disregarding the legal status of a company’s controlling shareholder whenever such status represents an impediment to receiving restitution for environmental damages.

In the civil sphere, environmental damage results in joint and several liability as well as strict liability. This means that the obligation to repair the environmental damage may affect all those directly or indirectly involved, regardless of any proof of who is to blame. As a result, the hiring of third parties to intervene in its operations to perform such services as final disposal of solid waste does not exempts the Company from liability for any environmental damage that may occur.

North American Environmental Legislation

The Company is required to comply with a complex and evolving body of Environmental, Health and Safety Laws (EHS Laws) concerning, among other things, air emissions, discharges to soil, surface water and groundwater, noise control, the generation, handling, storage, transportation and disposal of toxic and hazardous substances and waste, the clean-up of contamination, indoor air quality and worker health and safety. These EHS Laws vary by location and can fall within federal, provincial, state or municipal jurisdictions.

Most EHS Laws are of general application but result in significant obligations in practice for the steel sector. For example, the Company is required to comply with a variety of EHS Laws that restrict emissions of air pollutants, such as lead, particulate matter and mercury. Because the Company’s manufacturing facilities emit significant quantities of air emissions, compliance with these laws does require the Company to make investments in pollution control equipment and to report to the relevant government authority if any air emissions limits are exceeded. The government authorities typically monitor compliance with these limits and use a variety of tools to enforce them, including administrative orders to control, prevent or stop a certain activity; administrative penalties for violating certain EHS Laws; and regulatory prosecutions, which can result in significant fines and (in rare cases) imprisonment. The Company is also required to comply with a similar regime with respect to its wastewater. EHS Laws restrict the type and amount of pollutants that Company facilities can discharge into receiving bodies of waters, such as rivers, lakes and oceans, and into municipal sanitary and storm sewers. Government authorities can enforce these restrictions using the same variety of tools noted above. The Company has installed pollution control equipment at its manufacturing facilities to address these emissions and discharge limits, and has an environmental management system in place designed to reduce the risk of non-compliance.

Environmental Permits

According to Brazilian environmental legislation, the proper functioning of activities considered effectively or potentially polluting or that in some way could cause environmental damage requires environmental licenses. This procedure is necessary for both the activity’s initial installation and operating phases as well as for its expansion phases, and these licenses must be renewed periodically.

The Brazilian Institute for the Environment and Renewable Resources (IBAMA) has jurisdiction to issue licenses for projects with national or regional environmental impacts. In all other cases, the state environmental agencies have jurisdiction and, in the case of local impact, the municipal agencies have jurisdiction.

Environmental licensing of activities with significant environmental impacts is subject to a Prior Environmental Impact Study and respective Environmental Impact Report (EIA/RIMA), as well as the implementation of measures to mitigate and compensate for the environmental impact of the project. In the case of compensatory measures, the environmental legislation imposes on the project’s owner the obligation to set aside funds equivalent to at most 0.5% of the total estimated cost of installing the project to implement and maintain conservation units.

The environmental licensing process includes the issuance of three licenses: Pre-License (LP), Installation License (LI) and Operational License (LO). These licenses are issued in accordance with each phase of project implementation, and maintaining their validity requires compliance with the requirements established by the environmental licensing agency. The failure to obtain an environmental license, regardless of whether or not the activity is actually harming the environment, is considered an environmental crime and an administrative infraction, subjecting the violator to administrative fines, at the federal level (subject to being doubled or tripled in the case of repeat violations), and the suspension of operations. The Operational License (LO) must be renewed periodically.

The Company’s operations currently comply with all legal requirements related to environmental licenses. However, any delay or refusal on the part of environmental licensing agencies to issue or renew these licenses, as well as any difficulty on its part to meet the requirements established by these environmental agencies during the course of the environmental licensing process, could jeopardize or even impair the installation, operation and expansion of new and current projects.

Areas of permanent forest preservation and legal reserves

Some of the Company’s activities, mainly those involving reforestation related to the production of the firewood used in its industrial units, are subject to the Brazilian Forestry Code.

The Brazilian Forestry Code determines that certain areas, because of their importance for preserving the environment and water resources, be considered permanent preservation areas (APP). These include areas adjacent to rivers or natural or artificial reservoirs, and hilltops and hillside properties with an incline steeper than 45°. Suppression of the vegetation in these areas may only occur in cases of public need or social interest, provided previous authorization is obtained from the appropriate environmental agencies.

In addition, the Brazilian Forestry Code requires rural property owners to restore and preserve from 20% to 80% of areas containing native forests, depending on the region where the property is located. On properties where the extent of native forest does not meet the minimum percentage of legal forest reserves, Executive Order 2166-67/2001 mandates the gradual reforestation of at least one-tenth (1/10) of the area necessary to complete the legal percentage of forest reserve every three years until the percentage required for that location is achieved.

Executive Order 2166-67/2001 also establishes alternative methods for restoring legal forest reserve areas, which may be adopted successively or cumulatively. These alternative methods constitute compensatory measures, such as: the adoption of a condominium system consisting of more than one property; compensation using another area situated within the same micro basin or hydrographic basin in the state; the leasing of an area under the public forest system with right-of-way; or the acquisition of interests in forest reserve areas created specifically for this purpose.

ITEM 4A. UNRESOLVED SEC STAFF COMMENTS

The Company has no unresolved comments from the staff of the U.S. Securities and Exchange Commission with respect to its periodic reports under the Securities Exchange Act.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A. OPERATING RESULTS

The following discussion of t he Company’s financial condition and operating results should be read in conjunction with t he Company’s audited consolidated financial statements as of December 31, 2011, 2010 and 2009 included in this Annual Report that have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standard Board (IASB) as well as with the information presented under “Presentation of Financial and Other Information” and “Selected Financial and Other Information of Gerdau”.

The following discussion contains forward-looking statements that are based on management’s current expectations, estimates and projections and that involve risks and uncertainties. T he Company’s actual results may differ materially from those discussed in the forward-looking statements as a result of various factors, including those described in the sections “Forward-Looking Statements” and “Risk Factors”.

The primary factors affecting the Company’s operating results include:

· Economic and political conditions in the countries in which Gerdau operates, specially Brazil and U.S.;

· The fluctuations in the exchange rate between the Brazilian real and the U.S. dollar;

· The cyclical nature of supply and demand for steel products both inside and outside of Brazil, including the prices for steel products;

· The Company’s level of exports; and

· The Company’s production costs.

Brazilian Economic Conditions

The Company’s results and financial position depend largely on the situation of the Brazilian economy, notably economic growth and its impact on steel demand, financing costs, the availability of financing and the exchange rates between Brazilian and foreign currencies.

Table of Contents

Since 2003, the Brazilian economy has become more stable, with significant improvement in the main indicators. The continuity of the macroeconomic policies focused on tax matters, the inflation-targeting system, the adoption of a floating foreign exchange rate, the increase in foreign investment and compliance with international financial agreements, including the full repayment of debt with the International Monetary Fund, contributed to the improved economic conditions in Brazil.

In 2009, Brazilian GDP slightly fell by 0.6% remaining at $1.6 trillion, with a trade surplus of $25 billion. Inflation, as measured by the IPCA index, stood at 4.3%. The average CDI rate in the year was 9.9%. The Brazilian real appreciated by 25.5% against the U.S. dollar, ending the year at R$1.74 to $1.00.

In 2010, Brazilian GDP grew by 7.5% to $2.1 trillion, with a trade surplus of $20 billion. Inflation, as measured by the IPCA index, was 5.9%. The average CDI rate in the year was 10.6%. On December 31, 2010, the U.S. dollar/Brazilian real foreign exchange rate was R$1.67/$1.00.

In 2011, Brazilian GDP grew by 3.8% to $2.5 trillion. Inflation, measured by the IPCA index, was 6.5% and the average CDI rate in the year was 10.9%. On December 31, 2011 the U.S. dollar/Brazilian real foreign exchange rate was R$1.88/$1.00.

Inflation affects Gerdau’s financial performance by increasing operating expenses denominated in Brazilian reais. A significant portion of its costs of sales and services rendered, however, are linked to the U.S. dollar and are not substantially affected by the Brazilian inflation rate.

Moreover, a significant portion of the Company’s debt denominated in Brazilian reais is subject to interest at the CDI and TJLP rates, which are affected for many factors including inflation in Brazil. Another portion of the Company’s debt, denominated in Brazilian reais, is indexed to general-inflation indexes, generally the IGP-M index. Therefore, higher inflation may results in increases in the Company’s financial expenses and debt service obligations.

The interest rates that the Company pays depend on a variety of factors such as; movements on the interest rates, which can be driven by inflation; ratings given by the credit rating agencies that assess the Company; as well as the Company’s debt securities that are traded in the secondary market, as bonds. The Company’s debt obligations with floating interest rates, exposes the Company to market risks from changes in the CDI rate, IGP-M index and LIBOR. To reduce its exposure to interest rate risk, the Company seeks from time to time to enter into hedging arrangements to mitigate fluctuations in these rates, such as LIBOR.

The table below presents GDP growth, inflation, interest rates and the foreign exchange rate between the U.S. dollar and the Brazilian real for the periods shown.

U.S. Economic Conditions

In view of the size of the Company’s operations in the United States, U.S. economic conditions have a significant effect on the Company’s results, particularly with regard to U.S. economic growth and the related effects on steel demand, financing costs and the availability of credit.

In the United States, Real GDP began to fall in the third quarter of 2008 (down 2.7% annualized) before falling at a 5.4% annual rate in the fourth quarter of 2008 as uncertainty and tight credit conditions led companies to preserve cash, leading to a drawdown in inventories throughout the supply chain. Inventory reduction continued on a much wider scale in the first quarter of 2009, accounting for about one-half of the estimated 6.4% drop in annualized Real GDP. The second quarter of 2009 saw demand begin to stabilize, with Real GDP falling at a 0.7% pace as domestic demand and inventories bottomed out. Supported by the “Cash for Clunkers” program, which drove a sharp rise in auto sales, and first-time homebuyer incentives, which supported improved housing starts, Real GDP in the United States grew by 5.7% in the fourth quarter of 2009, as re-stocking of inventories outweighed the continued negative impact of rising unemployment on consumption. During 2010 and 2011, the United States economy kept showing a gradual recovery, with an increase in the demand for steel products. The improvements in the automotive sector and in the manufacturing industry were the drivers of the recovery in demand. The Institute for Supply Management (ISM), the main indicator of industrial production in North America, remained above 50, indicating growth. The infrastructure and non-residential segments continue to present stable demand.

In 2009, according to IMF (International Monetary Fund) the U.S. Real GDP decreased by 2.6% ($14.1 trillion Nominal GDP), with a trade deficit of $378.4 billion. Deflation, as measured by the CPI, was 0.3%. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) was 0.2%.

In 2010, U.S. Real GDP grew by 2.6% ($14.6 trillion Nominal GDP), with a trade deficit of $466.5 billion, according to the International Monetary Fund (IMF). Inflation in 2010 measured by the CPI was 1.6%. The average Fed Funds rate was 0.2%.

In 2011, U.S. Real GDP 1.5% ($15.1 trillion Nominal GDP), with a trade deficit of $467.6 billion, according to the International Monetary Fund (IMF). Inflation, measured by the CPI was 3.0%.The average Fed Funds rate was 0.1%.

The table below presents actual U.S. Real GDP growth, inflation and interest rates for the periods indicated.

Impact of Inflation and Fluctuations in Exchange Rates

Gerdau’s results and its financial position are largely dependent on the state of the Brazilian economy, notably (i) economic growth and its impact on steel demand, (ii) financing costs and the availability of financing, and (iii) the rates of exchange between the Brazilian real and foreign currencies.

For many years, Brazil experienced high inflation rates that progressively eroded the purchasing power of the vast majority of the population. During periods of high inflation, effective salaries and wages tend to fall because the frequency and size of salary and wage adjustments for inflation usually do not offset the actual rate of inflation. Since the introduction of the Brazilian real in July 1994, the inflation rate in Brazil has decreased dramatically. Following the implementation of the Real Plan, Brazilian GDP has accelerated, growing by 2.7% in 2002, contracting by 1.1% in 2003, and growing by 5.7% in 2004, 3.2% in 2005, 4.0% in 2006, 6.1% in 2007, 5.1% in 2008, decreasing 0.6% in 2009 and growing by 7.5% in 2010 and 3.8% in 2011.

A portion of Gerdau’s trade accounts receivable, trade accounts payable and debt is denominated in currencies other than the respective functional currencies of each subsidiary. The functional currency of the Brazilian operating subsidiaries is the Brazilian real. Brazilian subsidiaries have some of their assets and liabilities denominated in foreign currencies, mainly the U.S. dollar.

The foreign exchange effect on translation of foreign subsidiaries is recorded directly in shareholders equity. Foreign exchange gains and losses on transactions, including the exchange gains and losses on some non-real denominated debt of the subsidiaries in Brazil are recognized in the statement of income. However, foreign exchange gains and losses designated as the hedged instrument of investment in foreign subsidiaries is also recognized directly in shareholders equity. The operations of Gerdau in Brazil have both liabilities and assets denominated in foreign currency, with the amount of assets exceeds the amount of liabilities. The effect of the valuation of the Brazilian real versus other currencies (mainly the U.S. dollar) has a net positive effect in our shareholders’ equity.

The cyclical nature of supply and demand for steel products including the prices of steel products

The prices of steel products are generally sensitive to changes in world and local demand, which in turn are affected by economic conditions in the world and in the specific country. The prices of steel products are also linked to available installed capacity. Most of the Company’s long rolled steel products, including rebars, merchant bars and common wire rods, are classified as commodities. However, a significant portion of the Company’s long rolled products, such as special steel, wire products and drawn products, are not considered commodities due to differences in shape, chemical composition, quality and specifications, with all of these factors affecting prices. Accordingly, there is no uniform pricing for these products.

Over the last ten years, annual world crude steel production volume has varied from between approximately 850 million tonnes and 1.500 million tonnes. According to the worldsteel, world crude steel production in 2011 was 1,527 million tonnes, 6.8% higher than in 2010, a reflection of the recovery in the world economy increasing the demand for steel products. China continued to increase its crude steel production by 10.5% in 2011, mainly due to massive public spending on infrastructure projects. According to worldsteel, world demand for finished steel products increased by 6.5% in 2011 and should grow 5.4% in 2012.

International steel prices increased around 42.4% over the last five years (2007-2011), due to stronger demand from China, which has led steelmakers to invest in new projects to expand installed capacity. On the other hand international steel prices have experienced ups and downs throughout the period from the fourth quarter of 2007 and through the fourth quarter of 2009, when the average price per tonne of CIS export billet at Black Sea/Baltic Sea was $512 in the fourth quarter of 2007, skyrocketing to $1.205 in June 2008, slumping to $295 in March 2009 and reaching $415 at the end of 2009. This swing in the steel price was mainly caused by the turmoil in the world economy and the surplus supply of steel products in a scenario of lower demand in the period. During 2010 and 2011 the prices recovered, increasing by 41.6% when compared to 2009, reaching $588 in the end of 2011.

The average price per tonne of the CIS export billet at the Black Sea/Baltic Sea is used as a reference for the international price, and it is possible to see its evolution in the chart below:

Export levels - during periods of lower domestic demand for the Company’s products, the Company actively pursues export opportunities for its excess production in order to maintain capacity utilization rates and shipments. During periods of higher domestic demand for its products, export sales volumes may decline as the Company focuses on satisfying domestic demand. In the past three years, we exported products from Brazil to customers in other continents

with whom we have long-established commercial relations. In 2011, exports were 3.8% higher when compared to 2010, reaching 2.0 million tonnes, which represented 28% of all sales by our Brazilian units, in 2010 exports represented 29% of total sales from Brazil operations. Export revenue totaled R$ 2.3 billion in the year (excluding revenue from shipments to subsidiaries and affiliated companies).

Production costs - raw materials account for the highest percentage of the Company’s production costs. Metallic inputs, that includes scrap, pig iron, iron ore, coke and metallic alloys, represented in 2011 approximately 54.2% of production costs, while Energy and Reducing Agents, that represents cost with coal, electricity, oxygen, natural gas and fuel oil, accounted for 13.5%. Personnel totaled 14.3% of production costs and Specific Materials that includes refractories, electrodes, rolling cylinders, rollers, guides, carburants and lime sum 7.6% of total production costs. The chart below presents the costs breakdown:

Production Costs Breakdown in 2011

Significant events affecting financial performance during 2011

Capital increase - On April 18, 2011, the Company concluded a public offering, with net proceeds in the amount of R$ 3.6 billion. Of this figure, R$ 2.1 billion were used for the prepayment of loans contracted by the Company’s subsidiaries in North America, which led to a reduction in the financial expenses, and the remaining amount was incorporated to corporate funds, resulting in higher financial income. Based on such event, the net debt index on EBITDA went from 2.4x in December 31, 2010 to 2.0x by the end of 2011.

Exchange rate — In 2010, the foreign exchange variation between the US dollar and the real in the period (an appreciation of the real against US dollar of 4.3%), resulted the positive amount of R$ 104.4 million. On the other hand, in 2011, pursuant to IFRS standards, the Company assigned most of the debts in foreign currency acquired by companies in Brazil as hedge for a portion of investments in subsidiaries abroad. As a result, the effects from foreign currency variations on such debts are recognized as shareholders’ equity, mitigating the impact on the Company’s financial result in 2011. Thus, even with the depreciation of the real against US dollar of 12.6% in 2011, the foreign exchange variation recorded a positive amount of R$ 51.8 million.

In 2011, consolidated net sales increased by 12.8% compared to 2010, due to higher shipments (10.4% increase) and higher net sales per ton sold (2.2% increase). Consolidated shipments in 2011 increased throughout all business operations, especially in the North America Business Operation.

Increased net sales in the North America Business Operation have been due to the 13.7% increase in shipments, and 7.6% increase in net sales per ton - from R$ 1,539 in 2010 to R$ 1,656 in 2011. The manufacturing industry has been the main driver of the shipments recovery in this business operation. The Institute for Supply Management (ISM), the main industrial production indicator in the USA, remained above 50 for the last 2 years, indicating growth. In addition, the number of unemployment benefits applications significantly decreased throughout 2011, which strongly indicates an increase in steel consumption in the region. In light of the stronger demand in the manufacturing industry, the Company has been expanding its exposure to this consumer market, having increased exposure to this market, going from 20% of shipments in previous years to more than 30% in 2011.

Net sales for the Brazil Business Operation have increased slightly in 2011 due to higher shipments (+6.3%). On the other hand, net sales per ton sold have negatively impacted net sales, having decreased by 2.2% - from R$ 1,958 in 2010 to R$ 1,915 in 2011. This decrease reflects the discounts given to clients in the domestic market during the fourth quarter of 2010 to ensure competitiveness against long steel imports to Brazil. These new levels of net sales per ton sold have not increased significantly in 2011.In the Brazil Business Operation, the civil construction industry, which accounts for 50% to 55% of this Business Operation’s sales, has played an important role in maintaining this demand. According to Sinduscon, the civil construction industry’s GDP is expected to grow by 5% in 2012, which indicates a strong demand in this industry in the Brazilian market. For more details, please see Trend Information.

Net sales for the Special Steel Business Operation have increased driven by the growth in shipments (+6.0%) and the increased net sales per ton sold (+7.2%). In this business operation, the shipments sold in the Spanish (+17.8%) and United States (+6.1%) operations have been noteworthy. The shipments increase was a result of the recovery in the automotive industry in 2011, whose production of commercial vehicles increased by 9.6% in the U.S.A., and the number of commercial vehicle registrations increased by 9.9% in the European Union. The automotive industry is the main consumer market of this Business Operation, and it is expected to maintain its momentum in 2012, based on the forecasts of automotive associations in Brazil and in the United States. For more details, please see “Trend Information”.

In the Latin America Business Operation, the 25.7% growth in net sales was mostly due to increased shipments (+19.4%), noteworthy being the civil construction market in the operations in Colombia, Argentina and Chile. Net sales per ton sold have also contributed to increased net sales, going from R$ 1,577 in 2010 to R$ 1,660 in 2011. According to Worldsteel, Latin American countries are expected to experience a 5% growth in steel consumption in 2012, which indicates ongoing strong demand for this business operation.

On a consolidated basis, the cost of sales increase in 2011 when compared to 2010 is a result of the increase in shipments during the period, as well as the higher prices of raw materials, particularly metal inputs, which represented 48.8% of the cost of sales in 2010 and increased to 50.0% in 2011 (increase of R$ 2,523 million). The greater increase in raw material costs compared to the growth in net sales per ton sold derived from the decreased gross margin, particularly in the Brazil and Special Steel Business Operations.

The Brazil Business Operation presented a decrease in net sales per ton sold in 2011, mainly due to discounts provided in the local market during the second semester of 2010, which affected the 2011 gross margin, compared to the previous year. Additionally, the gross margin was also affected by the increase in raw material costs.

In the Special Steel Business Operation, raw material costs exceeded the increase in net sales per ton sold, which explains the five percentage point reduction in the gross margin.

In the North America and Latin America Business Operations, the cost of sales followed the net sales, which maintained the gross margin in similar levels on the comparison between 2011 and 2010.

In 2011, in line with the increase of shipments, selling expenses increased by 9.4% when compared to 2010. On the other hand, general and administrative expenses stayed in the same level, even with the higher operatinal activity level, due to the Company’s efforts to reduce costs. Therefore, selling, general and administrative expenses as a percentage of the net sales decreased in the comparison periods, going from 7.5% in 2010 to 6.8% in 2011.

Reversal of Impairment (Impairment) of Assets and Restructuring Costs

In accordance with the International Financial Reporting Standards (IFRS) as issued by the International Accounting Standard Board (IASB), Gerdau’s assets undergo impairment testing based on revisions of the prospects for cash generation and the future earnings from the Company’s operations.

In 2010, due to the more favorable market conditions observed at the Special Steel Business Operations, especially in the United States, the impairment testing of assets identified net gains of R$ 336 million in the period (R$ 208 million net of income tax), composed of the following effects: in the United States, there was a reversal of losses due to the impairment of intangible assets in the amount of R$ 216 million, and of fixed assets in the amount of R$ 188 million; in Spain, the lack of prospects for a recovery in these operations led to loss due to impairment of fixed assets at one of its units in the amount of R$ 68 million.

In 2011, impairment tests indicated no gains or losses due to impairment of the Company’s assets.

Equity in Earnings of Unconsolidated Companies

Jointly-controlled entities and associate companies, whose results are assessed by equity accounting, traded 1.1 million tons of steel in 2011, considering their respective equity interests, aligned with the shipments in the previous year, resulting in net sales of R$ 1.7 billion, a 16% increase compared to 2010. Based on such companies’ performance, equity accounting was positive by R$ 63 million in 2011, compared to a positive R$ 39 million in 2010.

Income before Financial Income (Expenses) and Taxes

The Net Income before Financial Results and Taxes decreased from R$ 3,644.6 in the fiscal year ended on December 31, 2010 to R$ 2,879.0 million in 2011, as explained in the “Cost of Sale and Gross Income” item.

In 2011, financial income and expenses were positively affected by the public offering concluded on April 18, 2011. Part of the resources obtained from the offering was used in the prepayment of debts, which reduced financial expenses (negative R$ 1,097.6 million in 2010 compared to also negative R$ 970.5 million in 2011), and the remaining balance was held in cash, resulting in higher financial income (R$ 295.6 million in 2010 and R$ 455.8 in 2011). Prepayment generated a loss of R$ 68.7 million, recorded under gains (losses) with financial instruments due to the anticipated settlement of interest rate swaps associated to such debt.

Pursuant to IFRS standards, the Company assigned most of the debts in foreign currency acquired by companies in Brazil as hedge for a portion of investments in subsidiaries abroad. As a result, the effects from foreign currency variations on such debts are recognized as shareholders’ equity, mitigating the impact on the Company’s financial result in 2011. In 2010, a significant portion of the debt was still not assigned as hedge and, therefore, its exchange variation had a bigger impact in the financial result.

Income and Social Contribution Taxes

Provisions for income tax amounted to R$ 253.1 million in 2011 compared to R$ 501.9 million in 2010. This variation was mostly due to decreased financial results in the period in comparison with the same period of the previous year, as well as tax benefits due to interests paid on capital stock in the 2011 financial year.

Net Income

Consolidated net income was reduced in 2011 by 14.6% compared to 2010, mainly due to the decrease in operating results. It is important to mention that consolidated net income in 2010 had a loss reversal due to non-recoverability of assets totaling R$ 336.3 million (R$ 208.0 million, net of taxes).

At the Brazil Business Operation net income was R$ 989.4 million in 2011, 16.5 % lower than in 2010, mainly due to the weaker operational result.

In 2011 the North America Business Operation had net income of R$ 470.5 million compared to a net income of R$ 147.6 million in 2010, a consequence of better operational results in 2011 and the lower financial expenses related to the payment of the term loan (R$ 2,058.2).

Table of Contents

In 2011 the Latin America Business Operation had net income of R$ 160.9 million, 28.7% lower than in 2010, a consequence of higher financial expenses due to an increase in the debt level in some countries in this business operation.

The Special Steel Business Operation had net income of R$ 496.3 million compared to net income of R$ 886.1 million in 2010, a consequence of a lower financial revenue due to pay down of loans from affiliates.

In 2010, consolidated net sales increased 18.3% in relation to 2009 (see table above), driven by the increased shipments (+24%), despite the lower net sales per tonne sold (-4.7%). In 2010, consolidated shipments grew in all business operations, especially in those operations with greater exposure to the Brazilian market and to the auto industry.

In absolute figures, the Brazil Business Operation was the highlight of net sales growth in 2010, supported by the increased shipments (+28.4%), especially in the Brazilian market (+29.2%). This growth in shipments compensated the reduction of 6.1% in net sales per tonne, from R$ 1,997 in 2009 to R$ 1,875, driven by price discounts granted to customers in the domestic market during the fourth quarter of 2010, in order to be more competitive, when the appreciation of the Real stimulated imports of long steel products to Brazil. In the Brazil Business Operation, the manufacturing industry, which represents from 40 to 45% of these Business Operation shipments, played an important role in the recovery in demand, fueled by the 21% growth in capital goods production in 2010, according to the Brazilian Institute of Geography and Statistics (IBGE). In the Brazilian market, demand remains robust in the construction industry, as confirmed by the growth of 11.6% in Construction GDP forecast for 2010, according to Sinduscon, an industry trade union. Construction represents from 50% to 55% of the Brazilian Business Operation shipments. Considering the consistent GDP growth forecasted for Brazil and the future events coming on stream like Olympic Games and World Cup, the industry and construction segments should continue in a sustainable level. For further details, see “Trend Information”.

The Special Steel Business Operation also posted significant growth in net sales, led by the shipments growth (+ 48.4%) at its operations in Brazil (+ 45.2%) and the United States (+64.0%). This growth in shipments compensated

Table of Contents

the reduction of 6.8% in net sales per tonne, from R$ 2,566 in 2009 to R$ 2,392 in 2010, mainly in Brazil and Spain. In the Special Steel Business Operation, the highlights in shipments were the operations in Brazil and the United States, which benefitted from the strong recovery in the auto industry, with vehicle production growing 14% in Brazil and 36% in the United States. The automotive industry is the main consumer market of this Business Operation and should continue in a good pace for the rest of 2011, taking in consideration the forecast from the automobile associations in Brazil and USA. For further details, see “Trend Information”.

The North America Business Operation posted growth in net sales, led by the shipments growth of 16.4% partially offset by the reduction of 8.4% in the net sales per tonne, from R$ 1,681 in 2009 to R$ 1,539 in 2010 due to the devaluation of the US dollar against the real in the period. In the North America Business Operation, the manufacturing industry was also the main driver of the recovery in shipments. The Institute for Supply Management (ISM), the main indicator of industrial production in North America, reached 58.5 in December 2010, with a reading above 50 indicating growth. The infrastructure and non-residential segments continued to present weak and stable demand. Considering the better demand from manufacturing industry, the Company has been increasing its exposure to this consuming market, which used to be around 20% of shipments in previous years and now is close to 30%.

The Latin America Business Operation posted similar performance, with growth in net sales, led mainly by the shipments growth of 9.7%, especially in its operations in Argentina and Mexico, countries in which GDP growth was estimated at 9% and 5%, respectively. Net sales per tonne slightly increased from R$ 1,557 in 2009 to R$ 1,577 in 2010.

(*) The information above does not include data from jointly controlled entities and associate companies.

On a consolidated basis, the increase in cost of sales in 2010 from 2009 (see table above) is explained by the increase in shipments in the period and the higher raw material prices, mainly metallic inputs, which represented 37% of sales cost in 2009 and increased to 49% in 2010 (an increase of R$ 4,393 million). However, the increase in cost of sales was lower than the increase in net sales due to the higher dilution of fixed costs, which led to gross margin expansion, especially in the Special Steel and Latin America Business Operation.

In the Special Steel Business Operation, as mentioned above, the increase in cost of sales was lower than the increase in net sales due to the higher dilution of fixed costs, a consequence of increased shipments (+48.4%). This can be evidenced by the reduction of 18.4% in cost of sales per tones compared to a decrease of 6.8% in net sales per tonne during the compared period. This performance led to a significant increase in gross profit and margin.

Table of Contents

The North America Business Operation presented the same performance, but in a lesser extent. The increase in cost of sales was lower than the increase in net sales due to the higher dilution of fixed costs, a consequence of increased shipments (+16.4%), which can be evidenced by the reduction of 10.8% in cost of sales per tonne compared to a decrease of 8.4% in net sales per tonne during the compared period. This performance led to an increase in gross profit and margin.

In the Latin America Business Operation, the reduction in cost of sales compared to an increase in net sales due to the higher dilution of fixed costs allowed the growth in gross profit and margin.

In the Brazil Business Operation, despite the dilution of fixed costs due to the increased shipments in 2010, the mismatch between the increases in raw material prices and the pass-through to steel prices led to a reduction in gross profit and gross margin compression in relation to 2009.

In accordance with the International Financial Reporting Standards (IFRS) as issued by the International Accounting Standard Board (IASB), Gerdau’s assets undergo impairment testing based on revisions of the prospects for cash generation and the future earnings from the Company’s operations.

In 2009, the Company recognized an impairment of assets in the amount of R$1.1 billion and restructuring costs of R$151 million which was mainly generated by downward revisions in expectations for operating results in the North America and Special Steel business operations.

In 2010, due to the more favorable market conditions observed at the Special Steel Business Operations, especially in the United States, the impairment testing of assets identified net gains of R$ 336 million in the period (R$ 208 million net of income tax), composed of the following effects: in the United States, there was a reversal of losses due to the impairment of intangible assets in the amount of R$ 216 million, and of fixed assets in the amount of R$ 188 million; in Spain, the lack of prospects for a recovery in these operations led to loss due to impairment of fixed assets at one of its units in the amount of R$ 68 million.

Equity in Earnings of Unconsolidated Companies

Associate companies and jointly controlled entities, which results are calculated using the equity method, recorded shipments of 1.1 million tonnes of steel in 2010 (based on their respective equity interests), which was 20% more than in 2009, resulting in net sales of R$ 1.4 billion. Based on these companies’ results, equity income was a gain of R$ 39 million in 2010, versus a loss of R$ 109 million in 2009.

Income before Financial Income (Expenses) and Taxes

Income before Financial Income (Expenses) and Taxes increased from R$ 846.9 million in the year ended December 31, 2009 to R$3,644.6 million in 2010. This difference is due to an improvement in the Company’s shipments, better results of Equity in earnings of unconsolidated companies in the year ended December 31, 2010 and negative impact of the impairment test recognized in 2009.

The lower foreign exchange variation between the US dollar and the real in the period (an appreciation of the real against US dollar of 25.5% in 2009, versus 4.3% in 2010) was the main factor responsible for the negative financial result in the period, which compares with the positive financial result recorded last year. In 2009, Gerdau’s financial result included a gain from the appreciation of the Brazilian real against the U.S. dollar in the period on the translation of foreign-denominated asset balances (export receivables) and liability balances (primarily dollar-denominated debt contracted by Brazilian companies) in the amount of R$ 1,060.9 million. In 2010, this gain amounted only R$ 104.4 million.

Of the total foreign-currency debt of US$ 3.5 billion contracted by companies in Brazil as of December 31, 2010, US$ 2.7 billion was related to the acquisitions of companies abroad, for which foreign exchange variation was recorded directly on the equity (net investment hedge in relation to some investments). For the remaining US$ 0.8 billion, the foreign exchange gains or losses are recorded on the income statement.

Income and Social Contribution Taxes

Income and Social Contribution Taxes increased from a negative amount of R$27.0 million in the year ended December 31, 2009 to a positive amount of R$501.9 million in the corresponding period of 2010, mainly due to more favorable results in 2010.

Net Income

In fiscal year 2010, consolidated net income increased by 144.5% when compared to 2009, from R$ 1,004.5 million to R$ 2,457.4 million, mainly due to the better operating results and the partial reversal of the negative impact of the asset impairment recorded in 2009, as explained above.

At the Brazil Business Operation net income was R$ 1,184.6 million in 2010, 48.8 % lower than in 2009, mainly due to the weaker operational result and the lower foreign exchange variation between the US dollar and the real in the period (an appreciation of the real against US dollar of 4.3% in 2010 — R$ 130.0, versus 25.5% in 2009 — R$ 1,236.7) in the translation into Brazilian real of the asset balances (export receivables) and liability balances (especially dollar-denominated debt contracted by Brazilian companies) at the end of each fiscal year.

In 2010 the North America Business Operation had a net income of R$ 147.6 million compared to a net loss of R$ 236.1 million in 2009, a consequence of better operational results in 2010 and the recognition of impairment of assets of R$ 214.4 million in 2009.

In 2010 the Latin America Business Operation had a net income of R$ 225.6 million compared to a net loss of R$ 324.5 million in 2009, a consequence of better operational results in 2010 and the recognition of impairment of assets of R$ 136.5 million.

In 2010 the Special Steel Business Operation had a net income of R$ 886.1 million compared to a net loss of R$ 613.5 million in 2009, a consequence of better operational results and the recognition of a reversal of impairment of assets in the amount of R$ 336.3 in 2010 against an impairment of assets of R$ 872.0 million in 2009.

Critical Accounting Policies

Critical accounting policies are those that are both (a) important to present the financial position and results of operations and (b) require Management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates that impact matters that are inherently uncertain. As the number of variables and assumptions affecting the possible future resolution of the uncertainties increases, those judgments become even more subjective and complex. In the preparation of the Consolidated Financial Statements, the Company has relied on variables and assumptions derived from historical experience and various other factors that it deems reasonable and relevant. Although these estimates and assumptions are reviewed by the Company in the normal course of business, the presentation of its financial position and results of operations often requires making judgments regarding the effects of inherently uncertain matters on the carrying value of its assets and liabilities. Actual results may differ from estimates based on different variables, assumptions or conditions. In order to provide an understanding of how the Company forms its judgments about future events, including the variables and assumptions underlying the estimates, comments have been included that relate to each critical accounting policy described below:

· deferred income and social contribution tax;

· pension and post-employment benefits;

· environmental liabilities;

· derivative financial instruments;

· useful lives of long-lived assets;

· fair value of unquoted derivative financial instruments,

· valuation of assets acquired and liabilities assumed in business combinations,

· business combination, and

· impairment test of assets with definite and indefinite useful life.

a) Deferred Income and Social Contribution Tax

The liability method of accounting (according to the concept described in IAS 12) for income taxes is used for deferred income and social contribution taxes arising from temporary differences between the book value of assets and liabilities and their tax bases. The amount of the deferred income and social contribution tax asset is revised at each Consolidated Financial Statement date and reduced by the amount that is no longer probable of being realized based on future taxable income. Deferred income and social contribution tax assets and liabilities are calculated using tax rates applicable to taxable income in the years in which those temporary differences are expected to be realized. Future taxable income may be higher or lower than estimates made when determining whether it is necessary to record a tax asset and the amount to be recorded.

The realization of deferred tax assets for tax loss carryforwards are supported by projections of taxable income based on technical feasibility studies submitted annually to the Company’s Board of Directors. These studies consider historical profitability of the Company and its subsidiaries and expectation of continuous profitability and estimated the recovery of deferred tax assets over future years. The other tax credits arising from temporary differences, mainly tax contingencies, and provision for losses, were recognized according to their estimate of realization.

b) Pension and Post-Employment Benefits

Actuarial gains and losses are recorded in the period in which they are originated and are recorded in the statement of comprehensive income.

The Company recognizes its obligations related to employee benefit plans and related costs, net of plan assets, in accordance with the following practices:

i) The cost of pension and other post-employment benefits provided to employees is actuarially determined using the projected unit credit method and management’s best estimate of expected investment performance for funded plans, salary increase, retirement age of employees and expected health care costs. The discount rate used for determining future benefit obligations is an estimate of the interest rate in effect at the balance sheet date on high-quality fixed-income investments with maturities that match the expected maturity of obligations.

60

Table of Contents

ii) Pension plan assets are stated at fair value.

iii) Gain and losses related to the curtailment and settlement of the defined benefit plans are recognized when the curtailment or settlement occurs and they are based in actuarial evaluation done by independent actuaries.

In accounting for pension and post-retirement benefits, several statistical and other factors that attempt to anticipate future events are used to calculate plan expenses and liabilities. These factors include discount rate assumptions, expected return on plan assets, future increases in health care costs, and rate of future compensation increases. In addition, actuarial computation other factors whose measurement involves judgment are used such as withdrawal, turnover, and mortality rates. The actuarial assumptions used by the Company may differ materially from actual results in future periods due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates, or longer or shorter participant life spans.

c) Environmental Liabilities

The Company records provisions for environmental liabilities based on best estimates of potential clean-up and remediation costs for known environmental sites. The Company has a team of professionals to manage all phases of its environmental programs. These professionals develop estimates of liabilities at these sites based on projected and known remediation costs. These analysis requires the Company to make significant estimates and changes in facts and circumstances may result in material changes in environmental provisions.

The steel industry uses and generates substances that may damage the environment. The Company’s management performs frequent surveys with the purpose of identifying potentially impacted areas and records as ‘current liabilities’ and in noncurrent liabilities in the account ‘Environmental liabilities’, based on best cost estimate, the amounts estimated for investigation, treatment and cleaning of potentially affected sites. The Company used assumptions and estimates for determining the estimated amount, which may vary in the future depending on the final investigations and determination of the actual environmental impact.

The Company is compliant with all the applicable environmental regulations in the countries where they operate (see note 20 of the Consolidated Financial Statements herein).

d) Derivative Financial Instruments

The Company values the derivative financial instruments considering mark to market obtained from market participants, which are the fair value of the financial instruments on the date of the Consolidated Financial Statements. Intense volatility in the foreign exchange and interest rate markets in Brazil has caused, in certain periods, significant changes in forward rates and interest rates over very short periods of time, generating significant changes in the fair value of swaps and other financial instruments over a short period of time. The fair value recognized in its Consolidated Financial Statements may not necessarily represent the amount of cash that the Company would receive or pay, as applicable, if the Company would settle the transactions on the Consolidated Financial Statements date.

e) Useful Lives of Long-Lived Assets

The Company recognizes depreciation of its long-lived assets based on estimated useful lives, which are based on industry practices and prior experience and reflect economic lives of long-lived assets. However, actual useful lives can vary based on technological update of each unit. Useful lives of long-lived assets also affect impairment tests of those long-lived assets, when required.

The Company does not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions used to calculate long-lived asset impairment losses. However, if actual results are not consistent with estimates and assumptions used in estimating future cash flows and asset fair values, the Company may be exposed to losses that could be material.

f) Fair Value of Unquoted Derivative Financial Instruments

The Company has entered into financial instruments in connection with some of its acquisitions, which involve commitments to acquire shares from non-controlling interests of the acquired companies, or grant of put options to some non-controlling interests to sell to the Company their shares. Such derivatives are recorded on the Company’s balance sheet in the account ‘Put options on non-controlling interest’ (note 15.f of the Consolidated Financial Statements herein), and the determination of this value involves a series of estimates that can materially impact its final result. The Company estimates the fair value of the companies whose shares the Company is committed to acquire using criteria established in each contract, which are in line with practices observed in the market for estimating fair value of unquoted instruments.

g) Valuation of Assets Acquired and Liabilities Assumed in Business Combinations

During the last several years, as described at note 3 of the Consolidated Financial Statements, the Company has made certain business combinations. According to IFRS 3, with effect for business combinations occurred after the IFRS transition date, the Company should allocate the cost of the acquired entity to the assets acquired and liabilities assumed based on their fair value estimated on the date of acquisition. Any difference between the cost of the acquired entity and the fair value of the assets acquired, liabilities assumed is recorded as goodwill. The Company exercises significant judgment in the process of identifying tangible and intangible assets and liabilities, valuing these assets and liabilities, and estimating their remaining useful life. The valuation of these assets and liabilities is based on assumptions and criteria that, in some cases, include estimates of future cash flow discounted at the appropriate rates. The use of valuation assumptions includes discounted cash flows estimates or discount rates and may result in estimated values that are different from the assets acquired and liabilities assumed.

The Company does not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions used to complete the purchase price allocation and estimate the fair value of acquired assets and liabilities. However, if actual results are not consistent with estimates and assumptions considered, the Company may be exposed to losses that could be material.

The accounting treatment for business acquisitions as from January 1, 2010 changed, if compared to previous years, because the IASB issued a revised version of IAS 27 and IFRS 3. These changes are primarily related to accounting for non-controlling interests, the loss of control of a subsidiary and increase/decrease in interest in a subsidiary without change of control. The revised Standards have resulted in changes in the Company’s accounting policies regarding increases or decreases in ownership interests in its subsidiaries. The adoption of this change in accounting policy is expected to affect the accounting for changes in ownership interest as from January 1, 2010, with no impact in business acquisitions performed up to December 31, 2009.

h) Business Combination

Step-acquisitions in which control is obtained

When a business combination is achieved in stages, the interest previously held by the Company in the acquired company is remeasured at fair value at acquisition date (in the date when the Company acquires the control) and the resulting gain or loss, if any, is recognized in the profit or loss. The amounts of interests on the acquired company before the acquisition date that was recognized on “Other comprehensive income” are reclassified in income, where such treatment would be appropriate in case this interest was sold.

Acquisitions in which control is obtained initially

Acquisitions of subsidiaries and businesses are accounted under the purchase method. The cost of the acquisition is measured at the aggregate of the fair values (at the date of exchange) of assets given and liabilities incurred or assumed and equity instruments issued by the Group in exchange of the control of the acquired control. The acquiree’s identifiable assets, liabilities and contingent liabilities are recognized at their fair values at the acquisition date. The interest of non-controlling shareholders in the acquiree is initially measured at the non-controlling shareholder’s proportion of the net fair value of the assets, liabilities and contingent liabilities recognized.

Under the previous version of the Standard, contingent consideration was recognized at the acquisition date only if payment of the contingent consideration was probable and it could be measured reliably; any subsequent adjustments to the contingent consideration were recognized against goodwill. Under the revised Standard, contingent consideration is measured at fair value at the acquisition date; subsequent adjustments to the consideration are recognized against goodwill only to the extent that they arise from better information about the fair value at the acquisition date, and they occur within the ‘provisional period’ (a maximum of 12 months from the acquisition date). All other subsequent adjustments are recognized in profit or loss.

Increases/decreases in non-controlling interests

In prior years, in the absence of specific requirements in IFRS, increases in interests in existing subsidiaries were treated in the same manner as the acquisition of subsidiaries, with goodwill or a bargain purchase gain being recognized where appropriate.

The impact of decreases in interests in subsidiaries that did not involve loss of control (being the difference between the consideration received and the carrying amount of the share of net assets disposed of) was recognized in profit or loss. Under the revised standards, all increases or decreases in such interests are accounted for within equity, with no impact on goodwill or profit or loss.

62

Table of Contents

Subsequent purchases, after the Company has obtained control, are treated as the acquisitions of shares from non-controlling shareholders: the identifiable assets and liabilities of the entity are not subject to a further revaluation and the positive or negative difference between the cost of such subsequent acquisitions and the net value of the additional proportion of the company is accounted for within equity.

Loss of control of a subsidiary

When control of a subsidiary is lost as a result of a transaction, event or other circumstance, the revised Standard requires that the Company derecognizes all assets, liabilities and non-controlling interests at their carrying amount. Any retained interest in the former subsidiary is recognized at its fair value at the date that control is lost. This fair value is reflected in the calculation of the gain or loss on disposal attributable to the parent, and becomes the initial carrying amount for subsequent accounting for the retained interest under IAS 28, IAS 31 or IAS 39.

The Company does not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions used to complete the purchase price allocation and estimate the fair value of acquired assets and liabilities. However, if actual results are not consistent with estimates and assumptions considered, the Company may be exposed to losses that could be material.

i) Impairment Test of Assets with definite and indefinite useful life

There are specific rules to assess the impairment of long-lived assets, especially property, plant and equipment, goodwill and other intangible assets. On the date of each Financial Statement, the Company performs an analysis to determine if there is evidence that the carrying amount of long-lived assets is impaired. If such evidence is identified, the recoverable amount of the assets is estimated by the Company.

The recoverable amount of an asset is determined as the higher of: (a) its fair value less estimated costs of sale and (b) its value in use. The value in use is measured based on discounted cash flows (before taxes) derived from the continuous use of the asset until the end of its useful life.

Regardless of whether or not there is any indication that the carrying amount of the asset may not be recovered, the balances of goodwill arising from business combination and assets with indefinite useful life are tested for impairment at least once a year, in December.

When the residual carrying value of the asset exceeds its recoverable amount, the Company recognizes a reduction in this asset’s book balance.

For assets recorded at cost, the reduction in recoverable amount must be recorded in income for the year. If the recoverable amount of an asset is not determined individually, the recoverable amount of the business segment to which the asset belongs is analyzed.

Except for the impairment of goodwill, a reversal of previously recorded impairment losses is allowed. Reversal in these circumstances is limited up to the amount of depreciated balance of the asset at the date of the reversal, determined considering as if the impairment had not been recorded.

The Company evaluates the recoverability of goodwill on investments annually and uses accepted market practices, including discounted cash flow for units with goodwill allocated and comparing the book value with the recoverable amount of the assets.

Recoverability of goodwill is evaluated based on the analysis and identification of facts and circumstances that can indicate the necessity to anticipate the test that is performed annually. If some fact or circumstance indicates that the recoverability of goodwill is affected on an interim period, then the test is anticipated. In December 2011, the Company carried out goodwill impairment tests for all of its operating segments, which represent the lowest level at which goodwill is monitored by management based on projections for expected discounted cash flows and that take into consideration the following assumptions: cost of capital, growth rate and adjustments used for perpetual cash flows, methodology for determining working capital, investment plans, and long-term economic-financial forecasts.

In December 2011, the Company performed an impairment test for the goodwill on the operating segments and it was not identified impairment loss for the year.

The projection period for the December 2011 cash flows was five years. The premises used to determine the fair value through the discounted cash flow method include: projected cash flow based in the Management estimates to the future cash flows, discount rates and growth rates to the perpetuity determination. Moreover, the perpetuity was calculated considering the stabilization of the operational margins, levels of working capital and investments. The perpetuity growth rate considered was 3% p.a. to the Brazil, Latin America, Specialty Steels and North America segment.

63

Table of Contents

The discount rates used were determined taking into consideration market information available on the test date. The Company adopted distinct rates to each business segment tested with the objective of demonstrate the differences among the markets in which each segment operate, as well as risk associated to them. The discount rates used were 9.0% p.a. to the North America segment (11.25% in December, 2010), 10.5% p.a. to the Special Steel segment (12.5% in December, 2010), 10.75% p.a. to Latin America segment (12.75% in December, 2010) and 11.0% p.a. to the Brazil segment (13.0% in December, 2010).

Considering the recoverable amount identified through the discounted cash flows, the recoverable amount exceeded the book value in R$ 9,849.8 million to the North America segment (R$ 2,126.7 million in December 2010), R$ 4,295.6 million to the Special Steel segment (R$ 2,738.7 million in December 2010), R$ 1,977.1 million to the Latin America segment (R$ 113.3 million in December 2010), and R$ 7,430.0 million to the Brazil segment (R$ 4,877.7 million in December 2010).

Due to the cash flow potential impact of discount rate and perpetuity growth rate variables, the Company performed a sensitive analysis of changes in these variables. A 0.5% increase in the discount rate to the cash flow of each segment would result in recoverable amounts that would exceed the book value in R$ 8,227.3 million to the North America segment (R$ 1,378.5 million in December 2010), R$ 3,672.8 million to the Special Steel segment (R$ 2,293.2 million in December 2010), R$ 6,032.6 million to the Brazil segment (R$ 3,659.1 million in December 2010) and R$ 1,502.5 million to the Latin America segment (recoverable amount that would be lower the book value in R$ 182.8 million in December 2010).

On the other hand, a 0.5% decrease in the perpetuity growth rate in the discounted cash flow to each segment would result in recoverable amounts that would exceed the book value in R$ 8,636.2 million to the North America segment (R$ 1,646.3 million in December 2010), R$ 3,866.0 million to the Special Steel segment (R$ 2,444.2 million in December 2009), R$ 6,467.8 million to the Brazil segment (R$ 4,072.9 million in December 2010) and R$ 1,645.1 million to Latin America segment (recoverable amounts that would be lower than the book value in R$ 74.9 million in December 2010).

Goodwill that forms part of the carrying amount of an investment in an associate or in a jointly-controlled entity is not separately recognized and it is not tested for impairment separately. Instead, the entire carrying amount of the investment in an associate or in a jointly-controlled entity is tested for impairment as a single asset, by comparing its recoverable amount (higher of value in use and fair value less costs to sell) with its carrying amount. An impairment loss recognized in those circumstances is not allocated to any asset, including goodwill that forms part of the carrying amount of the investment in the associate or jointly-controlled entity. Accordingly, any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases.

Goodwill originated in a business combination has the recoverability evaluated in an annual basis, and it is anticipated if events or circumstances indicate the necessity. The test considers accepted market practices, including cash flows and compares the book value with its fair value. The reversal of goodwill impairment losses previously recognized from business combination is not allowed. Annually, in December, the Company performs impairment tests for all operating segments, which represents the lowest level in which goodwill is monitored by the management.

The recoverability review process is subjective and requires significant judgments through analysis performed. The determination of fair value for Company’s operating segments, based on projected cash flows may be negatively impacted if the economy global recovery happens slowly than expected during the preparation of financial statements in December 2011.

Additional information related to impairment of goodwill and other long lived assets are described at note 27 of Consolidated Financial Statements contained herein.

B. LIQUIDITY AND CAPITAL RESOURCES

Gerdau’s usual main source of liquidity is the cash generated by its operating activities. Moreover, the Company counts on committed credit facilities. The Company expects to meet its cash needs for 2012 primarily through a combination of operating cash flow, cash and cash equivalents, short-term investments and capital increase from the public offering.

Cash and cash equivalents totaled R$ 1,476.6 million, R$ 1,061.0 million and R$ 2,091.9 on December 31, 2011, 2010 and 2009, respectively, as analyzed below:

Net cash provided by operating activities

Net cash from operating activities totaled R$ 1,710.0 million, R$ 4,139.1 million and R$ 6,350.6 in the fiscal years ended on December 31, 2011, 2010 and 2009, respectively.

In 2011, the net cash from operating activities decreased by 58.7% in relation to 2010. This reduction resulted mainly from increased investments on trading securities, due to the Company’s capital increase in April, 2011.

In 2010, net cash from operating activities decreased by 34.8% due to new demand levels, which resulted from economic recovery of the international financial crisis and the resulting increased production, which, in turn, affected the Company’s working capital needs. From December 31, 2009 to December 31, 2010, the working capital (comprising receivables from clients, plus inventories, minus suppliers) increased by 23.1%, going from R$ 6,632.2 million in the year ended on December 31, 2009 to R$ 8,167.5 million in 2010, affected mainly by increased inventories and receivables.

Net cash used in investing activities

Net cash used in investing activities increased by 31.7%, going from R$ 1,603.1 million in the year ended on December 31, 2010 to R$ 2,111.2 million in 2011, largely due to fixed asset acquisitions in 2011 in connection with the Company’s investment plan, particularly in the Brazil business operation.

Net cash used in investing activities increased by 52.9%, going from R$ 1,048.3 in the year ended on December 31, 2009 to R$ 1,603.1 in 2010, particularly due to the investment of R$ 1,269.5 million on fixed and intangible asset acquisition, and R$ 283.1 million used to pay the acquisition of Tamco.

Net cash used in financing activities

Net cash yielded by financing activities went from R$ 3,498.6 million in the year ended on December 31, 2010 to R$ 727.1 million in 2011, which reflects the capital increase due to the public offering. Additionally to this operation, part of the capital increase was used to prepay debts in the amount of R$ 2,058.2 million.

In April 2011, the Board of Directors of Gerdau S.A. approved the issuance of 68,026,910 common shares and 134,830,100 preferred shares, resulting in a capital increase of approximately R$ 3.7 billion, pursuant to a fully registered public offering. On April 18, 2011, the financial settlement of the public offering took place, with a net resource addition of R$ 3.6 billion in the Company’s funds.

Net cash used in financing activities decreased by 29.1% going-from R$ 4,933.6 million in the year ended on December 31, 2009 to R$ 3,498.6 million in 2010, which is mainly a result of a reduction in loan and financing amortization, despite payment of minority control acquisitions (particularly Gerdau Ameristeel) and increased dividend distribution.

In 2010, the Company repaid loans and financing in the amount of R$ 3,453.2 million related to the prepayment of the Perpetual Bond in a total of US$ 600 million (R$ 1,031 million) and Gerdau Ameristeel’s term loan of US$ 430 million (R$ 739 million). The Company also paid R$ 2,909.0 million for interest increase in subsidiaries, mainly the acquisition of the non-controlling interest in Gerdau Ameristeel. In 2009, the Company repaid loans and financing in the amount of R$ 8,469.9 million. This amount was due to the amortizations and prepayments made in the period, such as the Senior Notes of its U.S. subsidiary, Gerdau Ameristeel, a redemption of US$ 405 million (R$ 764 million) with annual coupon of 10.375% and maturity in 2011. The total value of the redemption was US$ 412.3 million (R$ 777.8 million). Gerdau Ameristeel also prepaid US$ 300 million (R$ 522 million) in debt. Another important impact was the foreign exchange variation effect of 25.5% in the period over the debt contracted in U.S. dollar.

The proceeds of loans and financing amounted to R$ 3,885.9 million in 2010 and R$ 4,089.4 million in 2009. In 2010, the Company issued a 10-year maturity bond to pay for acquisitions (non-controlling interests from Gerdau Ameristeel and Tamco) and prepay certain loans and financings.

(1) The calculation of net debt is made by subtracting short-term investments, cash and cash equivalents from total debt. Net debt is not a GAAP measure recognized under IFRS and should not be considered in isolation from other financial measures. Other companies may calculate net debt differently and therefore this presentation of net debt may not be comparable to other similarly titled measures used by other companies.

Total debt amounted to R$ 13,683.5 million, R$ 14,670.0 million and R$ 14,520.9 million in the years ended December 31, 2011, 2010 and 2009, respectively. Net debt (Net Debt is a non-gaap metric defined as short- and long-term debt plus debentures less short and long-term investments and cash and cash equivalents, broadly used by investors to measure Company’s indebtedness position) decreased from R$ 12,466.7 million in 2010 to R$ 9,105.3 million in 2011. This decrease of R$ 3,361.4 million is mainly due to the capital increase of R$ 3,597.8 million concluded in April 2011. Net debt increased from R$ 9,701.6 million in 2009 to R$ 12,466.7 million in 2010. This increase of R$ 2,765.1 million is due to a reduction in short and long-term investments, cash and cash equivalent mainly to pay the acquisition of non-controlling interest of Gerdau Ameristeel.

Of the total debt at December 31, 2011, 12.8% was short-term and 87.2% was long-term. In 2010, 11.5% was short-term and 88.5% was long-term and in 2009, short-term debt accounted for 9.3%, while the remaining balance was long-term.

Of this total, R$ 426.0 million was related to financing in Brazilian reais and R$ 673.2 million to financing in foreign currencies.

As of December 31, 2010, the Company’s short-term debt amounted to R$ 951.9 million. Of this total, R$ 157.1 million was related to financing in Brazilian reais and R$ 794.8 million to financing in foreign currencies.

Covenants

As an instrument to monitor the financial condition of the Company by its creditors, financial covenants are used in certain financial agreements.

All covenants mentioned below are calculated based on the Consolidated Financial Statements under IFRS of Gerdau S.A., except item IV, which refers to the Consolidated Financial Statements of Metalúrgica Gerdau S.A., as described below:

I) Consolidated Interest Coverage Ratio — measures the interest expense payment capacity in relation to EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization). The contractual ratio requires that the EBITDA for the

69

Table of Contents

last 12 months should represent at least 3 times of the interest expense of the same period. As of December 31, 2011 such covenant was 4.3 times.

II) Consolidated Leverage Ratio — measures the level of gross debt in relation to EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization). The contractual ratio requires that the gross debt should not surpass 4 times the EBITDA for the last 12 months. As of December 31, 2011 such covenant was 2.9 times.

III) Required Minimum Net Worth — measures the minimum net worth required in financial agreements. The contractual ratio requires that the Net Worth must be greater than R$ 3,759,200. As of December 31, 2011, the Net Worth was R$ 26.5 billion; and

IV) Current Ratio — measures the company’s ability in fulfilling its short term obligations. The contractual terms requires that the ratio of Current Assets divided by Current Liabilities must be greater than 0.8 times. As of December 31, 2011 the current ratio was 2.6 times.

The Company discloses to the market the adjusted EBITDA (earnings before interest, income tax and social contribution, depreciation, amortization and reversal (losses) from the non recoverability of assets and restructuring costs). EBITDA is not a measure used in generally accepted accounting practices and does not represent cash flow in the periods presented, and therefore should not be considered an alternative to cash flow as a liquidity indicator. EBITDA is not standardized and thus is not comparable to the EBITDA of other companies.

Pursuant to the agreements, the penalty for non-compliance with such covenants is the possibility of a declaration of default by the banks and acceleration of maturity of the Company’s loans.

As of December 31, 2011 and as of the date of this Annual Report on Form 20-F, the Company was in compliance with all contractual covenants related to its financial agreements.

Based on the Company’s internal forecasts, the Company does not expect to be in breach of any of the financial covenants over the next twelve months. Nevertheless, this forecast can be affected positive or negatively by the global economics and the steel market.

Derivatives

Risk management objectives and strategies: The Company believes that risk management is important to carry out its strategy for profitable growth. The Company is exposed to market risks that mainly involve fluctuations in exchange rates and interest rate volatility. The objective of risk management is to eliminate possible unexpected variations in the performance of group’s companies as a result of this fluctuation.

The objective of derivative transactions is always related to mitigation of market risks as stated in our policies and guidelines, as well as to manage volatility in financial flows. The final assessment of results for each contract is measured at the end of each contract when the derivative contract is settled. The monitoring of the effects from these transactions is monthly performed by the Cash Management and Debt Committee, which discusses and validates the marking to market of these transactions. All gains and losses in derivative financial instruments are recognized by its fair value in the Consolidated Financial Statements of the Company.

By internal policy, the Company does not maintain a debt in a currency in which there is no corresponding cash generation.

Policy for use of derivatives: according to internal policy, the financial result must arise from the generation of cash from its business and not gains from the financial market. Therefore, it considers that the use of derivatives should be for non-speculative purposes and intended to hedge the Company from possible exposure to risks. The contracting of a derivative must have as corresponding hedged item an uncovered asset or liability, provided as the position is not leveraged. Criteria adopted for defining the notional amount of derivative financial instruments are linked to the amount of debt and or assets.

Policy for determining fair value: The criteria to determine the fair value of derivative financial instruments is based on the utilization of market curves for each derivative discounted to present value as of the calculation date. The methods and assumptions take into consideration the interpolation of curves, such as in the case of LIBOR, and according to each market where the company has exposure. The swaps, both on the asset and on the liability side, are estimated in separate and discounted to present value. The difference in the result between extremities generates the swaps market value. The amounts are calculated based on models and rates available in the market and which take into consideration both present and future market conditions. Amounts are gross before taxes. Due to changes in market rates, these amounts can change up to the maturity or in situations of anticipated settlement of transactions.

The derivative transactions may include: interest rate swaps, (both in the Libor dollar, as in other currencies) in currency swap, and NDF’s (Non Deliverable Forwards).

Swap Contracts

Interest rate swap

The subsidiary Gerdau Ameristeel Corp. settled in advance interest rate swap contract qualified as a cash flow hedge with mature between March 2012 and September 2013. These operations were contracted in order to reduce its exposure to the variation in LIBOR for the Term Loan Facility. Since the Term Loan Facility was contracted at floating LIBOR rates, the Company chose to exchange it for fixed rates, thereby improving cash flow predictability, as well as eliminating the floating LIBOR risk. As of December 31, 2011 the effect of these swaps in the statement of income was a loss of R$ 68,698, which was presented in the account “Gains and losses on derivatives, net” in the consolidated statement of income. The counterparts to this transaction were ABN Amro Bank, HSBC, and JP Morgan.

The Company through its subsidiary GTL Equity Investments Corp. settled swap of Exchange Coupon versus Libor with the bank JP Morgan which matured between December 21, 2010 and December 21, 2011. This operation was entered into in order to take advantage of the difference between the internal interest rate (exchange coupon) and the external interest rate (LIBOR). Because of this, the Company increases its exposure to the Brazil’s risk; however, this risk is related to its business. The fair value adjustment of these contracts as of December 31, 2011 results in a gain of R$ 3,722 which were presented in the account “Gains and losses on derivatives, net”.

The subsidiary Siderúrgica del Perú S.A.A. - Siderperú entered into a Libor interest rate swap contract whereby it receives a variable interest rate based on LIBOR and pays a fixed interest rate in US dollars. This contract has a notional value of US$ 35.71 million (R$ 66,985 as of December 31, 2011) and maturity date on April 3, 2014. This swap was contracted in order to minimize the risk of interest rate fluctuations (LIBOR) since the Company took on debt in dollars at floating rates for an amount greater than the swap. The fair value adjustment of this contract as of December 31, 2011 results in a net loss of R$ 3,674 presented in the statement of income. The counterparty to this transaction is Banco Bilbao Vizcaya -BBVA.

The subsidiary Gerdau Açominas S.A. entered into an interest rate swap with a notional value of US$ 350 million (R$ 656,530 as of December 31, 2011) and a maturity date of June 22, 2015, on which the financial charges agreed on the debt contract with Banco do Brasil, equivalent to LIBOR plus a percentage of interest, are exchanged for pre-determined interest rates. The fair value adjustment of this contract as of December 31, 2011 results in a net loss of R$ 1,339 presented in the statement of income. The counterparts of this operation are the following banks: HSBC, Citibank and Morgan Stanley.

C. RESEARCH AND DEVELOPMENT, PATENTS AND LICENCES, ETC.

All Gerdau mills have excellent quality management supported by a wide array of quality control tools. Product development projects are headed by specialists who use quality tools such as “Six Sigma”, a set of statistical methods for improving the assessment of process variables, as well as “Quality Function Deployment”, a methodology through which technicians can identify the full range of customer requirements.

Given this level of quality management, 45 mills are ISO 9001 or ISO TS 16949 certified. In general, production, technical services and quality teams are responsible for developing new products to meet customer and market needs.

The Company uses a quality management system developed in house that applies tests for product design, manufacturing processes and final-product specifications. A specially trained team and modern technologies also exist to assure the Company’s high standards of quality. The Company’s technical specialists make planned visits, some may be randomly selected and some are scheduled visits, to its customers to check on the quality of the products delivered by the Company in order to guarantee the final user satisfaction for products purchased indirectly.

Knowledge Management Portal is used to share information among all steel mills seeking performance improvements and leverage of process knowledge supported by Communities of Practice and technical specialists.

Due to the specialized nature of its business, the Company’s special steel mills are constantly investing in technological upgrading and in research and development. These mills are active in the automotive segment and maintain a technology department responsible for new products and the optimization of existing processes.

International machinery manufacturers and steel technology companies supply most of the sophisticated production equipment the Company uses. These suppliers generally sign technology transfer agreements with the purchaser and provide extensive technical support and staff training for the installation and commissioning of the equipment. The Company has technology transfer agreements with Nippon Steel, Kyoei Steel, Thyssen, Daido Steel and BSW.

As is common with mini-mill steelmakers, the Company usually acquires technology in the market rather than developing new technology through intensive research and development, since steelmaking technology is readily available for purchase.

Gerdau works continuously to monitor and anticipate the needs of its customers. For this, has a research and development centers in Brazil, the United States and Spain used to meet the markets for special steel, especially for the automotive industry. The Company invested in research and development R$ 127.5 million in 2009, R$ 214.7 million in 2010 and R$ 210.9 million in 2011.

The Company is not dependent on patents or licenses or new manufacturing processes that are material to its business.

D. TREND INFORMATION

Studies from the World Steel Association indicate that world steel consumption should grow by 5.4% in 2012, to reach 1.5 billion tonnes. About 70% of the world steel consumption should occur in the developing economies, which Gerdau has a representative portion of its operations.

According to data from the Brazilian Steel Institute, Brazil steel consumption is expected to grow 7%, reaching 26.7 million tonnes of steel in 2012, supported by solid GDP growth in the period. Brazilian Central Bank estimates call for GDP growth of 3.3% in the year. In the construction industry growth is expected to remain robust, with estimates from Brazilian Central Bank pointing to growth in Brazil’s civil construction of 5% in 2012, growth rate higher than in 2011. In the manufacturing industry the Brazilian Central Bank is projecting GDP growth of 3% in 2012 for the sector.

The IMF projects GDP growth in North America for 2012 at 1.8%. This positive outlook is also supported by data from the World Steel Association, which points to steel consumption growing by 5% in 2012 to reach 94 million tonnes. The highlight in this scenario is the expected continued recovery in industrial construction, especially for energy projects, and the expected need for investments in infrastructure projects over the coming years.

In Latin America (excluding Brazil), for 2012, the estimates are optimistic, with GDP in the region projected to grow by 3.6% in 2012. According to the World Steel Association, steel consumption in Latin America, excluding Brazil, should reach 42 million tonnes in 2012, a growth of 5% over 2011, which should support a gradual increase in per-capita steel consumption in the region, which still remains at low levels.

The outlook for the special steel market in 2012 is also positive. In the United States, medium and heavy vehicle production is forecasted to grow 10% in 2012. In Brazil, the ANFAVEA (Vehicle Manufacturers’ Association) forecasts vehicle production to grow 2% in 2012. In India, the vehicle production is estimated to grow14% in 2012, according to the Society of Indian Automobile Manufactures (SIAM).

Family Relationships

Jorge Gerdau Johannpeter, Germano Hugo Gerdau Johannpeter, Klaus Gerdau Johannpeter and Frederico Carlos Gerdau Johannpeter are brothers. André Bier Johannpeter is Jorge Gerdau Johannpeter’s son and Claudio Johannpeter is Klaus Gerdau Johannpeter’s son.

Arrangements

Gerdau has no agreement of any kind with shareholders, clients, suppliers or other parties with respect to the election of its officers or directors. There are no pending legal proceedings to which any Company Board Member or Executive Officer is a party against the Company. Apart from statutory severance benefits, none of the Board Members or Executive Officers is entitled to any contractual benefits upon termination of employment.

B. COMPENSATION

The employees’ compensation system is divided into two portions: a fixed salary and a variable pay linked to performance.

The fixed portion of the compensation is constantly monitored and compared to market benchmarks in order to maintain parity with the best market practices as adopted by other companies. The variable portion of the compensation package is tied to semi-annual and annual goals. These goals are measured against standards clearly specified that are intended to support and motivate overachievement of individuals and teams results.

The human resources policy states and recognizes co-workers as being strategic to the business.

The Company conducts evaluations based on several different methodologies, including competence mapping, to track the managerial skills of its executives. Competence mapping aims to identify the degree of alignment of executives with the Company’s strategies and business management and to monitor individual development.

Table of Contents

In 2011, Directors and Executive officers from Gerdau were paid a total of R$ 53.2 million in salaries and variable remuneration. The variable remuneration for executives is based on the overall performance of Gerdau, using as performance indicator, actual EBITDA versus planned EBITDA, on the performance of the unit to which the executive is responsible, and on individual performance. Each of the first two factors influencing 30% and the third 40% in the amount of the variable remuneration for more or less.

Gerdau Group co-sponsor Pension Plans to his subsidiaries, in Brazil, United States and Canada covering the majority of their employees. The plans are Defined Benefit plans (42%) and Defined Contribution (58%).

During 2011, Gerdau’s contribution to the Gerdau Plan with respect to the executive officers amounted to R$ 1.2 thousand. This sum includes only that portion of contributions for executives who do not currently receive retirement benefits from the Company. These benefits are in no way different from those offered to the other employees of the Company.

On April 30th, 2003, Gerdau’s shareholders approved a new compensation program for strategic employees in the Company known as the Long Term Incentive Program. This new compensation program foresees the grant of options of the Company’s Preferred Shares, on an annual basis, representing 20% of the annual base salary of each executive and, for the Directors and Executive Offices, an additional entrance bonus equivalent to 30% of the annual salary (the latter was eliminated as from April 28, 2005). From 2005 on, in order to match their potential total compensation to market measures, the Board members were granted a number of shares representing 120% of their base salary. This modification on the long term incentive program was approved by the Compensation and Succession Committee in February 2006. In 2007 the Committee on Remuneration and Succession approved the granting of options to the Chief Executive Officer (CEO) and the Chief Operating Officer (COO) in number equivalent to 50% of their annual base salaries. This program aims to attract and assure the long-term commitment of executives by allowing them to share in the growth of the Company, thereby enhancing the sense of participation in the business. (See Item 10. Additional Information — B. Memorandum and Articles of Association).

To meet the effort of aligning globally both the compensation programs and the business needs, the Human Resources team supported by the HAY Group Consultancy, expert in compensation related matters, reviewed the Long Term Compensation Program which was submitted to and approved by the Gerdau Compensation and Succession Committee during the meeting held on April 28, 2010.

The purpose of this new Plan is to attract, retain and motivate key employees as well as to stimulate the achievement of long term results by tying significant part of this compensation to a long term financial metric, in this case the ROCE (Return on Capital Employed).

The Chief Executive Officer (CEO), the Chief Operating Officer (COO), Board Members and Director positions and higher will have part of their Long Term Compensation tied to ROCE (Return on Capital Employed) calculated on a yearly basis by comparing the actual ROCE against the one foreseen in the Strategic Plan.

Under this program, the Chief Executive Officer (CEO) and the Chief Operating Officer (COO) are eligible to a grant equivalent to 50% of their annual base salary, the Board Members are eligible to a grant equivalent to 120% of their annual fixed compensation and other participants are eligible to a grant equivalent to 5% to 20% of their annual base salary.

The Compensation and Succession Committee approved all stock option grants since the program begun.

The stock option grants distributed to the Directors and Executive Officers are as follows (see Consolidated Financial Statements — Note 25.I for a complete summary of the stock option plans):

Grant date: To be vested from: Must be exercised by: Exercise price per share: |  | Dec/03 Jan/09 Dec/13 R$6.78 |  | Dec/04 Jan/10 Dec/14 R$10.58 |  | Dec/04 Jan/08 Dec/14 R$10.58 |  | Dec/05 Jan/11 Dec/15 R$12.86 |  | Dec/06 Jan/12 Dec/16 R$17.50 |  | Dec/07 Jan/13 Dec/17 R$26.19 |  | Dec/08 Jan/14 Dec/18 R$14.91 |  | Dec/09 Jan/15 Dec/19 R$29.12 |  | Dec/10 Jan/16 Dec/20 R$22.61 |  | Dec/11 Jan/17 Dec/21 R$14.42 |  | Accumulated Number of Shares |

C. BOARD PRACTICES

In November 2006, Gerdau announced a new phase in its corporate governance, marked by the fourth succession in five generations. This process began in 2000 and has already resulted in important structural changes in the organization, with emphasis on the creation of the Executive Committee in 2002.

The new structure was defined by the scale, complexity and challenges facing Gerdau in its global market operations. The best practices of the world’s large companies were also taken into account.

Gerdau has a historical commitment to good corporate governance practices and to strengthening the stock markets, which is why it takes part in Level 1 of the São Paulo Stock Exchange (Bovespa) Differentiated Corporate Governance program (since 2001 in the case of Gerdau S.A. and 2003 for Metalúrgica Gerdau S.A.).

Furthermore, the Group’s listed companies also have an information disclosure policy that defines the criteria guiding investor relations, including the announcement of relevant acts and facts. The aim is to maintain a fast and efficient flow of data while respecting rules of secrecy and confidentiality. This policy covers controlling shareholders, officers and managers, members of the Board of Directors and Board of Auditors and any organs or persons with technical or consultative functions which, as a result of their responsibilities, function or position, have access to information concerning the Group.

The structure is composed of three levels and has maintained the existing governing bodies — the Board of Directors, the Executive Committee and Business Operations Committee.

Board of Directors: The Board of Directors is responsible for determining the broad direction of the Group’s business. The Board may have up to eleven members; currently there are two independent Board members. The Board has three Committees: Corporate Governance; Strategy; and, Compensation and Succession. According to the Ordinary General Meeting of Shareholders, held on April 26, 2011, the members of the Board of Directors are:

Its activities are divided into business operations (BOs), defined by product line and/or geographical location: BO - Brazil, BO - Specialty Steel Products, BO - North America

and BO - Latin America. The Gerdau Executive Committee is also responsible for the main functional processes that operate vertically throughout the Group, such as finance, accounting, human resources and planning.

All members of the Board of Directors and the Gerdau Executive Committee are elected for one-year terms, with re-election or re-appointment permitted. Members of the Board of Directors are appointed at the Ordinary General Meeting of Shareholders while members of the Gerdau Executive Committee are elected at meetings of the Board of Directors.

Board of Auditors

Under Brazilian Corporate Law, the board of auditors (“Conselho Fiscal”) is a shareholder nominated audit board and an independent corporate body of the board of directors, the management and the company’s external auditors. The board of auditors has not typically been equivalent to or comparable with a U.S. audit committee; its primary responsibility has been to monitor management’s activities, review the financial statements, and report its findings to the shareholders. Pursuant to an exemption under Section 10A-3 of the SEC rules concerning the audit committees of listed companies, a foreign private issuer (such as the Company) need not have a separate audit committee composed of independent members if it has a Board of Auditors established and selected pursuant to its home country’s legal or listing provisions expressly requiring or permitting such a board and if such a board meets certain requirements. Pursuant to this exemption, a board of auditors can exercise the required duties and responsibilities of an U.S. audit committee to the extent permissible under Brazilian Corporate Law. To comply with the SEC rules, the Board of Auditors must meet the following standards: it must be separate from the full board of directors, its members must not be elected by management, no executive officer may be a member, and Brazilian law must set forth standards for the independence of the members. In order to qualify for exemption, the Board of Auditors must, to the extent permitted by Brazilian law:

· |  | be responsible for the appointment, retention, compensation and oversight of the external auditors (including the resolution of disagreements between management and the external auditors regarding financial reporting);
· |  | be responsible for establishing procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, and procedures for the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters;
· |  | have the authority to engage independent counsel and other advisors as deemed necessary, to carry out its duties; and
· |  | receive appropriate funding from the Company for payment of compensation to the external auditors, for any advisors and ordinary administrative expenses.

As a foreign private issuer, the Company decided to modify its Board of Auditors to comply with the exemption requirements. Accordingly, the Ordinary General Meeting of Shareholders held on April 28, 2005, amended the Company’s by-laws to modify the duties of the Board of Auditors and the Board of Directors, and, on the same date approved the delegation of certain additional responsibilities to the Board of Auditors. The Board of Auditors operates pursuant to a charter (“regimento interno”) that contemplates the activities described above to the extent permitted by Brazilian Law and is compliant with the requirements of the Sarbanes-Oxley Act, the pertinent regulations, and the requirements of the New York Stock Exchange and the “Conselho Fiscal”.

Because Brazilian Corporate Law does not permit the board of directors to delegate responsibility for the appointment, retention and compensation of the external auditors and does not provide the board or the board of auditors with the authority to resolve disagreements between management and the external auditors regarding financial reporting, the board of auditors cannot fulfill these functions. Therefore, in addition to its oversight responsibilities, the board of auditors may only make recommendations to the board of directors with respect to the appointment, retention and compensation of the external auditors. Likewise, the board of auditors may only make recommendations to management and the board with regard to the resolution of disagreements between management and the external auditors. This limited scope of authority is a key difference between the board of auditors and the customary authority of an audit committee as a full committee of the board of directors.

Under Brazilian Corporate Law, members of the board of auditors of a company are not allowed to be members of the board of directors, hold executive office, or be employed in any other position within that of the company or its

subsidiaries or controlled companies. In addition a member of the board of auditors cannot be spouse or relative of any member of the company’s management. In addition, the Brazilian Corporate Law requires that members of the board of auditors receive a remuneration at least 10% of the average amount paid to each executive officer. The Brazilian Corporate Law requires that a board of auditors be composed of a minimum of three and a maximum of five members and their respective alternates.

As part of the adaptation of its Board of Auditors to the regulations, the Company has installed a permanent (standing) Board of Auditors currently composed of three members and their alternates who are elected at the Ordinary General Meeting of Shareholders with term of office to run until the next Ordinary General Meeting of Shareholders following their election, reelection being permitted. Under Brazilian Corporate Law, holders of Preferred Shares have the right to elect through a separate vote, one member of the board of auditors to represent their interests. Likewise, minority groups of shareholders with voting shares also have the right to elect one member of the board of auditors through a separate vote. However, irrespective of circumstances, the common shareholders have the right to elect the majority of the members of the board of auditors. Set forth below are the names, ages and positions of the members of the Company’s Board of Auditors and their respective alternates, since April 26, 2011.

Table of Contents

* Outsourced correspond to employees of third-party service providers of Gerdau which provide, as employees of those providers, services directly to Gerdau in areas that are not the core business of Gerdau .

As of December 31, 2011, the Company employed 42,820 at its industrial units excluding joint ventures. 55% of this total is based in Brazil and the remainder in South America, North America and Europe, which have 6,009, 10,463 and 2,832 employees, respectively.

As labor unions in Brazil and other Countries in Latin America and Europe are organized on a regional basis, the Company has no nationwide agreements with its employees. Gerdau believes that its employee pay and benefits structure is comparable to the general market. 36% of the employees of Gerdau in North America are unionized.

Gerdau maintains good working conditions at its mills and consequently has what it believes to be a comparatively low employee turnover rate.

Gerdau has been and continues to be proactive in establishing and maintaining a climate of good employee relations. Ongoing initiatives include organizational development skills training, team-building programs, opportunities for participation in employee involvement teams, and an open book system of management. Gerdau believes that a high level of employee involvement is a key factor in the success of its operations. Compensation programs are designed to meet employee’s financial interests with those of Gerdau shareholders.

ITEM 8. FINANCIAL INFORMATION

A. CONSOLIDATED STATEMENTS AND OTHER FINANCIAL INFORMATION

The Company’s financial statements are included in Item 18.

Legal Proceedings

General

Like other Brazilian companies, Gerdau and its subsidiaries are party to proceedings with respect to tax, labor and civil matters, most of them arising in the regular course of business. Based on advice from legal counsel, management believes that the reserve for provisions is sufficient to meet probable and reasonably estimable losses in the event of unfavorable rulings, and that the ultimate resolution will not have a significant effect on its consolidated financial position of December 31, 2011.

The most significant legal and administrative disputes are detailed below. The amount disclosed for each dispute is as of December 31, unless otherwise stated. For further information on the reserve for contingencies, see Note 18 to the consolidated financial statements.

The following table summarizes the balances of provisions recorded for tax, civil and labor liabilities and related judicial deposits as of December 31, 2011, 2010 and 2009 (in thousands of reais):

Claims

|  | Reserve for Contingencies |  | Judicial Deposits |
|  | 2011 |  | 2010 |  | 2009 |  | 2011 |  | 2010 |  | 2009 |
Tax |  | 672,652 |  | 472,879 |  | 295,650 |  | 666,681 |  | 458,458 |  | 297,332 |
Labor |  | 217,696 |  | 153,752 |  | 141,507 |  | 37,829 |  | 31,676 |  | 26,167 |
Other |  | 17,370 |  | 12,470 |  | 10,014 |  | 8,970 |  | 3,413 |  | 1,179 |

Tax Provisions

Part of the provisions correspond to tax matters. The most significant provision of contingencies is related to:

· R$ 20 million related to Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS), the majority of which is related to credit rights involving the Finance Secretariat and the State Courts.

· R$ 21 million in Contributions allegedly due to the Social Security authorities, which are being challenged in tax foreclosure proceedings and suits for annulment pending before the Federal Courts.

· R$ 37 million related to the Emergency Capacity Charge (“Encargo de Capacidade Emergencial” — ECE), as well as R$ 24 million related to the Extraordinary Tariff Recomposition (“Recomposição Tarifária Extraordinária — RTE), which are charges included in the electric energy bills. The Supreme Court has upheld the constitutionality of the ECE, and for this reason, once the lawsuits are terminated, the reserve for contingency, will be released, as the amount in dispute, covered by deposits in court, will be fully paid. As to the RTE, the Company understands the charge as of a tax nature and, as such, incompatible with the National Tax System. For this reason the constitutionality of this charge is being challenged in court. The lawsuits are outstanding before the First and Second Instances of the Federal Justice. The Company has made a full deposit in court for the amount of the disputed charge.

· R$ 70 million related to discussions on Social Contribution Tax on Profits (“Contribuição Social sobre o Lucro” - CSLL ), mostly concerning the constitutionality and basis of calculation of the contribution.

· R$ 485 million related to (i) compensation of Contribution to the Social Integration Plan (“Contribuição ao Programa de Integração Social” - PIS) credits, (ii) taxation of Contribution to the Social Integration Plan (“Contribuição ao Programa de Integração Social” - PIS) and Social Security Financing Contribution (“Contribuição para o Financiamento da Seguridade Social” - COFINS) over income in excess of sales, and (iii) exclusion of the Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS) from the basis of

91

Table of Contents

calculation of the Contribution to the Social Integration Plan (“Contribuição ao Programa de Integração Social” - PIS) and Social Security Financing Contribution (“Contribuição para o Financiamento da Seguridade Social” - COFINS). In regards to proceedings explained in (ii) and (iii), the Company makes full deposit in courts.

There are other contingent tax liabilities, for which the probability of losses are not probable and, therefore, are not recognized in the provision for contingencies. These claims are comprised by:

· The Company is a defendant in debt foreclosures filed by the state of Minas Gerais to demand Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS) credits arising mainly from the sales of products to commercial exporters. The total amount of the lawsuits is R$ 60 million. The Company did not set aside a reserve for contingencies, since products for export are exempted from Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS) and no tax is payable.

· The Company and its subsidiary, Gerdau Aços Longos S.A., are defendants in tax foreclosures, which are claiming Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS) credits on the export of semi-finished manufactured products. The amount involved is R$ 80 million. Gerdau has not set aside a reserve for contingency for the lawsuits, as the products do not fit in the definition of semi-finished manufactured products as defined by federal complementary law and, therefore, are not subject to Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS).

· The Company and its subsidiary, Gerdau Aços Longos .S.A, are part in other Tax on Circulation of Goods and Services (“Imposto sobre a circulação de Mercadorias e Serviços” - ICMS) discussions, mostly related to credit rights and aliquot differences. The total amount of the discussions is R$ 84 million. No reserve for contingency was set aside for these claims, as the probability of loss is not probable.

· The Company and its subsidiaries, Gerdau Açominas S.A. and Gerdau Aços Longos S.A., are part in discussions related to other taxes for which no reserve for contingency was established, as the probability of loss is less likely than not. The total amount involved is R$ 138 million.

· The Company and its subsidiaries, Gerdau Internacional Empreendimentos Ltda. and Gerdau Aços Especiais S.A., are part in legal proceedings discussing taxation of Corporate Income Tax (IRPJ) and Social Contribution Tax on Profits (“Contribuição Social sobre o Lucro” - CSLL) over profits generated abroad, in the amount of R$ 1.235 million. The Company has not made a reserve for contingency, as its legal consultants consider the probability of loss as possible but not probable.

· The Company subsidiaries, Gerdau Aços Longos S.A., Gerdau Aços Especiais S.A., Gerdau Comercial de Aços S.A. and Gerdau Açominas S.A., have administratively challenged the disallowance of the deductibility of a premium generated through a corporate reorganization in 2005, in accordance with articles 7 and 8 of Law no. 9532/97. The premium was deducted from the tax bases of the income tax and social contribution on profits in the 2005-2010 period. The total updated amount under discussion is R$ 2,664 million. No reserve for contingency was established, since the Company believes, based on the opinion of its legal advisers, that the likelihood of an adverse decision is merely possible.

Labor Provisions

The Company is also defending labor proceedings, for which there is a provision as of December 31, 2011 of R$ 218 million. None of these lawsuits refers to individually significant amounts, and the lawsuits mainly involve claims due to overtime, hazardous and risk additional, among others. The balance in judicial deposits relate to labor provisions as at December 31, 2011, totaling R$ 38 million.

Other Provisions

The Company is also defending civil proceedings, other provisions arising from the normal course of its operations, which provisions for these claims amount to R$ 17.0 million. Judicial deposits related to these provisions, at December 31, 2011, amount to R$ 9 million. Other contingent liabilities with remote or possible chances of loss, involving uncertainties as to their occurrence, and therefore, not included in the provision for contingencies, are comprised of:

Antitrust Proceedings

Antitrust process involving Gerdau S.A. related to the representation of two civil construction syndicates in the state of São Paulo that alleged that Gerdau S.A. and other long steel producers in Brazil divide customers among them, violating the antitrust legislation. After investigations carried out by the National Secretariat of Economic Law —

92

Table of Contents

(“Secretaria de Direito Econômico”- SDE) and based on public hearings, the SDE is of the opinion that a cartel existed. The process was sent to the Administrative Council for Economic Defense — (“Conselho Administrativo de Defesa Econômica” — CADE), for judgment.

CADE judgment was put on hold by an injunction obtained by Gerdau S.A., which aimed at annulling the administrative process, due to formal irregularities. This injunction was cancelled by appeals made by CADE and the Federal Government, and CADE proceeded with the judgment. On September 23, 2005, CADE issued a rule condemning the Company and the other long steel producers, determining a fine of 7% of gross revenues less excise taxes of each company, based on the year before the commencement of the process, due to cartel practices. The Company has appealed from this decision, and the appeal is pending of judgment.

The Company has proposed a judicial proceeding aiming to cancel the administrative process due to the above mentioned formal irregularities. If the Company is successful in this proceeding, the CADE decision can be annulled in the future.

On July 26, 2006, due to a reversal of decision terms pronounced by CADE, the Company appealed to the Justice using a new ordinary lawsuit which point out irregularities in the administrative procedures conducted by CADE. The federal judge designated for the analysis of the fact decided, on August, 30, 2006 to suspend the effect of the CADE decision until a final decision is taken with respect to this judicial process and requested a guarantee through a stand-by letter amounting to 7% of gross revenue less taxes in 1999 (R$ 346 million). This ordinary lawsuit proceeds together with the injunction originally proposed on CADE. An order was announced on June 28, 2007, which made the parties aware of the decision from the lower court judge about the maintenance of the legal protection granted, after it was contested by CADE.

Prior to the CADE decision, the Federal Public Ministry of Minas Gerais (“Ministério Público Federal de Minas Gerais”) had presented a Public Civil Action, based on SDE opinion, without any new facts, accusing the Company of involvement in activities that breach antitrust laws. The Company presented its defense on July 22, 2005.

Gerdau S.A. denies having engaged in any type of anti-competitive behavior and understands, based on information available that the administrative process until now includes many irregularities, some of which are impossible to resolve. The Company believes it has not committed any violation of anti-trust regulation, and based on opinion of its legal advisors believes in a reversion of this unfavorable outcome.

Insurance Dispute

A civil lawsuit was filed by Sul América Seguradora on August 4, 2003 against Gerdau Açominas S.A. and Westdeutsche Landesbank Girozentrale for the payment of approximately R$ 34.4 million, which were deposited in court to settle an insurance claim made by Gerdau Açominas. In its defense, Gerdau Açominas asked for the payment of the unpaid balance at the time, corresponding to approximately R$ 311.5 million*, minus the amount received (approximately R$ 37.5 million*) as advance during the regulation process (to assess the amount due) and the amount paid in court.

The lawsuit is the result of an accident at the blast furnace regenerators that occurred on February 23, 2002, which caused loss of production, material damages and loss of profits. Gerdau Açominas initially asked for indemnification amounting to approximately R$ 160.7 million*, based on costs incurred in part of the period in which the equipment was out of service and costs incurred for temporary recovery thereof. During the regulation process (to assess the amount due), Gerdau Açominas received an advance of approximately R$ 37.5 million*. At the end of the regulation process, the insurance company ascertained that indemnification amounted to only R$ 59.3 million* (against which the advance of approximately R$ 37.5* million would be set-off) and conditioned payment of the balance (nearly R$ 21.6 million*) to a general release with respect to the accident, which was refused by Gerdau Açominas.

In view of the aforementioned events, Gerdau Açominas filed a suit to collect the undisputed amount. Concomitantly, Sul América Seguradora filed a suit against Gerdau Açominas and a third party (the bank) and deposited with the court the amount that it deemed appropriate as indemnification, corresponding to approximately R$34,4 million. It stated that it was unsure as to who should receive the payment and claimed that Gerdau Açominas had refused to receive the indemnification and give a general release. The amount deposited with the court was collected by Gerdau Açominas in December 2004. In their responses, the defendants made clear who should receive the payment and demonstrated the insufficiency of the amount deposited with the court. Gerdau Açominas also claimed that the insurance company should deposit the unpaid balance, in the amount of approximately R$ 311.5 million*, minus the amount received as advance during the regulation process (R$ 37.5 million*) and the amount paid in court, or that the court should determine the amount effectively due. Expert engineering accounting evidence is currently being compiled. Engineering and accounting analyses for such purpose are currently ongoing. Gerdau Açominas expects to be successful in the lawsuits.

*These amounts were originally claimed or stated in US dollars, and the exchange rate used to convert them into Reais was the official rate published by the Brazilian Central Bank (PTAX 800 transaction, option 5) on December 31, 2011 (R$1,8758).

Arbitration Proceedings (Confidential)

Arbitration proceedings of a confidential nature are currently ongoing, involving a possible loss for the Company of approximately R$ 22.3 million and a possible gain of approximately R$ 21.5 million.

No Material Effect

Management believes that the probability of losses as a consequence of other contingencies is remote, and that were they to arise, they would not have a materially adverse effect on the consolidated financial position of the Company, its consolidated results of operations or its future cash flows.

Dividend Distribution Policy

Brazilian Corporate Law generally requires the by-laws of each Brazilian corporation to specify a minimum percentage of the profits for each fiscal year that must be distributed to shareholders as dividends. The law requires a minimum payout of 25% of adjusted net income. Under the Company’s bylaws, this percentage has been fixed at no less than 30% of the adjusted net income (according the section 19 of the Company’s articles of association) for distribution for each fiscal year.

Dividends for a given fiscal year are payable from (i) retained earnings from prior periods and (ii) after-tax income for the same period, after the allocation of income to the legal reserve and to other reserves (“Adjusted Net Income”). In order to convert the dividends paid by the Company from reais into U.S. dollars, the institution providing the Company with custodial services (“Custodian”) will use the relevant commercial market exchange rate on the date that these dividends are made available to shareholders in Brazil. Under Brazilian Corporate Law, a Brazilian company is required to maintain a legal reserve, to which it must allocate 5% of net income determined in accordance with the Law for each fiscal year until such reserve reaches an amount equal to 20% of the company’s paid-in capital. On December 31, 2011, in accordance with Brazilian GAAP, Gerdau S.A.’s legal reserve amounted to R$407.6 million ($217.3 million, using the year-end exchange rate) or 2.1% of total paid-in capital of R$ 19,249.1 million ($10,261.8 million, using the year-end exchange rate).

According to Law 9,457, holders of Preferred Shares in a Brazilian corporation are entitled to dividends at least 10% greater than the dividends paid on Common Shares, unless one of three exceptions described in the Law holds. Gerdau S.A.’s executive directors presented a proposal at the 2002 shareholders’ meeting, to grant both Common and Preferred shares 100% tag-along rights. Shareholders approved this measure and the right was extended to all shareholders, even though the new Brazilian Corporate Law only requires that such rights be granted to the common minority shareholders (and only for 80% of the consideration paid to the controlling shareholders).

Under the amendments to the Brazilian Corporate Law, by extending the tag along rights to minority shareholders, the Company no longer needs to comply with the requirement to pay an additional 10% premium on dividends paid to preferred shareholders. Following the approval and implementation of the amendments to the Company’s bylaws to provide for the tag-along rights as described above, the Company now pays the stated minimum dividend of 30% of adjusted net profit (according the section 19 of the Company’s articles of association) to all shareholders, from January 1, 2002 dividends paid to preferred shareholders no longer being subject to a minimum 10% premium over those paid to holders of common shares.

As a general requirement, shareholders who are non-resident in Brazil must have their Brazilian company investments registered with the Central Bank in order to be eligible for conversion into foreign currency of dividends, sales proceeds or other amounts related to their shares for remittance outside Brazil. Preferred Shares underlying the ADRs will be held in Brazil by the Custodian as agent for the Depositary Bank (“Depositary”). The holder of Preferred Shares will be the registered holder recorded in the preferred shares register.

Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the Custodian, on behalf of the Depositary, which will then convert such proceeds into U.S. dollars and deliver the same U.S. dollars to the Depositary for distribution to holders of ADRs. If the Custodian is unable to convert the Brazilian currency received as dividends into U.S. dollars immediately, the amount of U.S. dollars payable to holders of ADRs may be adversely affected by any devaluation or depreciation of the Brazilian currency relative to the U.S. dollar that may occur before such dividends are converted and remitted. Dividends in lieu of the Preferred Shares paid to holders who are not resident in Brazil, including holders of ADRs, are not subject to Brazilian withholding tax.

Interest on Capital Stock

Law 9,249 of December 1995, provides that a company may, at its sole discretion, pay interest on capital stock in addition to, or instead of, dividends. A Brazilian corporation is entitled to pay its shareholders interest on capital stock up to the limit of an amount computed as the TJLP (Long-Term Interest Rate) rate of return on its interest on capital stock or 50% of the net income (according BR GAAP) for the fiscal year, whichever is the lower. The payment of interest as described herein is subject to a 15% withholding income tax. See Item 10. Additional Information — Taxation.

Dividend Policy

The Company currently intends to pay dividends on its outstanding Preferred Shares at its mandatory distribution rates for any particular fiscal year, subject to any determination by the Board of Directors that such distributions would be inadvisable in view of the Company’s financial condition. On March 31, 2003, the Board of Directors approved a new policy for paying dividends and interest on capital stock on a quarterly basis.

Since 1999, dividends have been paid to holders of the Company’s Common and Preferred Shares in reais and in U.S. dollars translated from reais at the commercial exchange rate on the date of payment. Relevant amounts are described in Item 3 — Key Information - Selected Financial Data.

On April 12, 2011, the Company carried out a primary public distribution of shares, issuing 68,026,910 common shares and 134,830,100 preferred shares, for a total capital increase of approximately R$ 3.7 billion. On the same date, a secondary public distribution was held that involved 69,000,000 preferred shares issued by Gerdau S.A. and owned by the shareholders Metalúrgica Gerdau S.A. and Gerdau BG Participações S.A., worth R$ 1.3 billion, which was fully used by the selling shareholders to subscribe and pay in common shares of the primary offering. Under the scope of the Global Offering, which includes the primary and secondary offerings, a total of approximately R$ 5.0 billion was raised, of which roughly R$ 3.7 billion was used for the capital increase at Gerdau S.A. Following said increase, the capital stock now stands at R$ 19.3 billion, divided into 573,627,483 common shares and 1,146,031,245 preferred shares, all of which are registered, book-entry shares with no par value. The issue price of the shares established after the book building process was R$ 15.60 per common share and R$ 19.25 per preferred share issued by Gerdau S.A. The

São Paulo Stock Exchange - Brasil

Trading on the BOVESPA

The São Paulo Stock Exchange (BOVESPA) is the only stock trade center in Brazil and Latin America’s largest stock exchange. Until August, 2007, BOVESPA was a non-profit association owned by its member brokerage firms and trading on the BOVESPA was limited to these member brokerage firms and a limited number of authorized nonmembers. On August 28, 2007, BOVESPA was subject to a corporate restructuring process that resulted in the creation of BOVESPA Holding S.A., a public corporation which had, as fully-owned subsidiaries, the São Paulo Stock Exchange S.A. (Bolsa de Valores de São Paulo S.A. — BVSP) — responsible for the operations by the stock exchange and the organized over-the-counter markets — and the Brazilian Clearing and Depositary Corporation (Companhia Brasileira de Liquidação e Custódia) — responsible for the settlement, clearing and depositary services. Such corporate restructuring has consolidated a demutualization process, thereby causing the access to the trading and other services rendered by the BOVESPA not conditioned to a stock ownership. On May 8, 2008, BOVESPA was subject to another corporate restructuring process that resulted in the creation of BM&F BOVESPA S.A. - Bolsa de Valores, Mercadorias e Futuros, a public corporation which merged the operations of BOVESPA Holding S.A. and BM&F S.A. On November 28, 2008, Brazilian Clearing and Depositary Corporation (Companhia Brasileira de Liquidação e Custódia), fully-owned subsidiary of BM&F BOVESPA S.A., was merged into BM&F BOVESPA S.A.

The BOVESPA’s trading is conducted between 10:00 a.m. and 5:00 p.m. on the BOVESPA automated system. There is also trading on the so-called After-Market, a system that allows for evening trading through an electronic trading system. Trades are made by entering orders in the Mega Bolsa electronic trading system, created and operated by BOVESPA. The system places a ceiling on individual orders of R$ 100,000 and price variations are limited to 2% (above or below) the closing quote of the day.

In order to better control volatility, the BOVESPA adopts a “circuit breaker” system pursuant to which trading sessions may be suspended for a period of 30 minutes or one hour whenever the index of the BOVESPA falls below the limits of 10% or 15%, respectively, in relation to the index registered in the previous trading session. If any circuit breaker takes place during the day, trading sessions thereafter may be suspended by a period of time to be determined as per BOVESPA’s own discretion whenever the index of the BOVESPA falls below the limit of 20% in relation to the index registered in the trading session of the day before.

Since March 17, 2003, market making activities have been allowed on the BOVESPA. The CVM (Comissão de Valores Mobiliários) and the BOVESPA have discretionary authority to suspend trading in shares of a particular issuer under certain circumstances. Trading of securities listed on the BOVESPA may be effected off the stock exchange market under certain circumstances, although such trading is very limited.

Although any of the outstanding shares of a listed company may trade on the BOVESPA, in most cases less than half of the listed shares are actually available for trading by the public, the remainder being held by small groups of controlling shareholders that rarely trade their shares. For this reason, data showing the total market capitalization of the BOVESPA tends to overstate the liquidity of the Brazilian equity market, which is relatively small and illiquid compared to major world markets.

Settlement of transactions is effected three business days after the trade date without adjustment of the purchase price for inflation. The seller is ordinarily required to deliver the shares to the exchange on the second business day following the trade date.

Trading on the BOVESPA by non-residents of Brazil is subject to certain limitations under Brazilian foreign investment legislation. See “Regulation of Foreign Investments in Brazil”.

Corporate Governance Practices in Brazil

In 2000, the BOVESPA introduced three special listing segments, known as Level 1 and 2 of Differentiated Corporate Governance Practices and the Novo Mercado, aimed at encouraging Brazilian companies to follow good corporate

99

Table of Contents

governance practices and higher levels of transparency, as required by Brazilian Corporate Law. The listing segments were designed for the trading of shares issued by companies voluntarily undertaking to abide by corporate governance practices and disclosure requirements in addition to those already imposed by Brazilian law. These rules generally increase shareholders’ rights and enhance the quality of information provided to shareholders.

The Company is listed on the Level 1 segment of the BOVESPA. To become a Level 1 company, in addition to the obligations imposed by current Brazilian law, an issuer must agree to (i) ensure that shares of the issuer representing at least 25% of its total capital are effectively available for trading; (ii) adopt offering procedures that favor widespread ownership of shares whenever making a public offering; (iii) comply with minimum quarterly disclosure standards, including cash flow statements; (iv) follow stricter disclosure policies with respect to transactions made by controlling shareholders, directors and officers; (v) disclose the terms of the transactions with related parties; (vi) make a schedule of corporate events available to shareholders; and (vii) at least once a year, hold public meetings with analysts and investors.

On March 21, 2011, the Securities and Exchange Comission of Brazil (CVM) approved the new text of the Corporate Governance Level 1 Listing Rules of BM&FBOVESPA that became effective on May 10, 2011. As of the effective date aforementioned, therefore, the companies listed on Level 1segment of BM&FBOVESPA are subject to what has been laid out in the Corporate Governance Level 1 Listing Rules, in accordance with the changes.

In order to be adapted to the changes to the Listing Rules, the companies listed in Level 1 segment must adopt the following provisions within the terms informed below:

a) Inclusion in the company bylaws of the mandatory minimum clauses set out by BM&FBOVESPA no later than: (i) the first Extraordinary General Meeting held 90 (ninety) days after the new Rules entered into force; or (ii) the date on which the company holds its general meeting to approve the financial statements; what happens first.

b) The preparation and publication of the Policy on Trading Securities and the Code of Conduct, which should occur within the deadline of one year as from the date on which the new Listing Rules came into force;

c) Compliance, as from May 10, 2014, with the rule contained in item 4.3 of the new Corporate Governance Level 1 Listing Rules, which consists of a prohibition on the accumulation of the position of Chairman of the Board of Directors and Chief Executive Officer or lead executive in the same company by a single person.

Regulation of the Brazilian Securities Market

The Brazilian securities markets are regulated by the CVM (Comissão de Valores Mobiliários), which has authority over stock exchanges and the securities markets generally, and by the Brazilian Central Bank, which has, among other powers, licensing authority over brokerage firms and regulates foreign investment and foreign exchange transactions. The Brazilian securities market is governed by the Brazilian Securities Law (Law N. 6,385 of December 7, 1976, as amended) and the Brazilian Corporate Law (Law N. 6,404 of December 15, 1976, as amended).

Law 11,638, of December 28, 2007, and Law N. 11,941, of May 27, 2009 (which resulted from the conversion into law of Provisional Decree (MP) N. 449, of December 3, 2008), amended a number of provisions of Law N. 6,385/76 and Law N. 6,404/76, related to accounting rules and financial statements of Brazilian corporations. The new changes aim to bring Brazilian accounting rules/financial statements closer to international standards.

Under the Brazilian Corporate Law, a company is either publicly held, such as Gerdau S.A., or closely held. All publicly held companies must apply for registration with the CVM and are subject to ongoing reporting requirements. A publicly held company may have its securities traded either on the BOVESPA or on the Brazilian over-the-counter markets (Brazilian OTC). The shares of a publicly held company, including Gerdau S.A., may also be traded privately subject to certain limitations established in CVM regulations.

CVM has issued Instruction N. 480, of December 7, 2009, that provides for the requirements for the registration of publicly held companies and companies that intend to trade securities in regulated securities markets. The referred CVM Instruction N. 480/09 significantly modified the reporting requirements applicable to publicly held companies and set forth the obligation to such companies to present annually to CVM a Reference Form (formulário de referência) containing all of the company’s relevant information and to update the information contained therein as soon as any relevant changes occur.

In addition to such reporting requirements, the occurrence of certain events also requires disclosure of information to the CVM, the BOVESPA, or even the public. These include (i) the direct or indirect acquisition by an investor of at least 5% (five percent) of any class or type of shares representing the share capital of a publicly held company, (ii) the sale of shares representing the transfer of control of a publicly held company and (iii) the occurrence of a material event to the corporation. On March 5, 2002, the CVM issued Instruction N. 361, which regulates tender offers if one of the following events occurs: (i) delisting of companies; (ii) an increase in the equity interest of the controlling shareholder; or (iii) the transfer of control of a public held company.

100

Table of Contents

The Brazilian OTC market consists of direct trades between individuals in which a financial institution registered with the CVM serves as intermediary. No special application, other than registration with the CVM, is necessary for securities of a publicly held company to be traded on the Brazilian OTC. The CVM must be notified of all trades carried out on the Brazilian OTC by the company’s respective intermediaries. The trading of a company’s securities on the BOVESPA may be suspended in anticipation of a material announcement. Trading may also be suspended at the initiative of the BOVESPA or the CVM on the basis of a belief that a company has provided inadequate information regarding a material event, has not provided an adequate response to the inquiries by the CVM or the stock exchange, or for other reasons.

The laws and regulations regarding the Brazilian Securities Market provide for disclosure requirements, restrictions on insider trading and price manipulation, and protection of minority shareholders. Although many changes and improvements have been introduced, the Brazilian securities markets are not as highly regulated and supervised as the U.S. securities markets or those in certain other jurisdictions.

Regulation of Foreign Investment in Brazil

Foreign investors may either register their investments in the Company’s shares as a foreign direct investment under Law N. 4,131/62 and CMN (Conselho Monetário Nacional) Resolution N. 3,844/10 or as a portfolio investment under CMN Resolution N. 2,689/00 and CVM Instruction N. 325/00, both as amended. Foreign investors, regardless of whether their investments are made as foreign direct investments or portfolio investments, must be enrolled with the RFB (Receita Federal do Brasil, the Brazilian internal revenue service) pursuant to its Regulatory Instruction N. 1,005, of February 08, 2010, as amended. This registration process is undertaken by the investor’s legal representative in Brazil.

Law N. 4,131/62 and CMN Resolution N. 3,844/10 provide that, after a foreign direct investment is made, an application for its registration with the Central Bank must be submitted by the investee and the non-resident investor, through its independent representatives in Brazil, within 30 days. The registration of the foreign direct investment with the Central Bank allows the foreign investor to remit abroad resources classifiable as capital return, resulting either from: (i) the transfer of corporate interests to Brazilian residents, (ii) capital reduction, or (iii) the liquidation of a company, as well as funds classified as dividends, profits or interest on shareholders’ equity. Foreign investors with foreign direct investments may also divest those investments through private transactions or transactions conducted through the stock exchange or the over-the-counter market. See “Taxation — Brazilian Tax Considerations” for information regarding the taxation of such transactions.

There are no restrictions on ownership of the Company’s shares by individuals or legal entities domiciled outside Brazil. With certain limited exceptions, under CMN Resolution N. 2,689/00 investors are permitted to carry out any type of transaction in the Brazilian financial and capital markets involving a security traded on a stock, futures or organized over-the counter markets. Investments and remittances outside of Brazil of gains, dividends, profits or other payments for common and preferred shares are made through the exchange market. See “Exchange Controls” for further information regarding non-Brazilian holders who qualify under CMN Resolution N. 2,689/00.

Securities and other financial assets held by non-Brazilian investors pursuant to CMN Resolution N. 2,689/00 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or the CVM. In addition, securities trading is restricted to transactions carried out in the stock exchanges or through organized over-the-counter markets licensed by the CVM, except for transfers resulting from a corporate reorganization, or occurring upon the death of an investor by operation of law or will.

Trading on Exchanges outside Brazil

In addition to the BOVESPA, Gerdau shares are traded on two other stock exchanges:

New York Stock Exchange

On March 10, 1999, Gerdau S.A. obtained registration for the issuance of Level II ADRs, which began trading on the New York Stock Exchange the same day. Under the GGB symbol, these Level II ADRs have been traded in virtually every session since the first trading day. In 2011, 2.3 billion ADRs were traded, a figure 37.5% higher than in 2010, representing a trading volume of $23.4 billion, equivalent to a daily average of $93.0 million.

Latibex — Madrid Stock Exchange

Since December 2, 2002, Gerdau S.A.’s preferred shares have been traded on the Latibex, the segment of the Madrid Stock Exchange devoted to Latin American companies traded in Euros. Following approval by the CVM and the Brazilian Central Bank, this date marked the beginning of the Depositary Receipts (DR) Program for preferred shares issued by the Company in Spain. The shares are traded in Spain under the symbol XGGB in the form of DRs, each corresponding to one preferred share. This participation in the Latibex boosted the Company’s visibility in the European market. In 2011, a total of 994 thousand Gerdau preferred shares were traded on the Madrid Stock Exchange (Latibex), a figure 42.7% lower than in 2010, representing a trading volume of $9.5 million, equivalent to a daily average of $37 thousand.

With regard to “borrowing powers exercisable by the directors”, the bylaws state that:

· Article 6, letter “u”: The Board of Directors should set on a periodic basis, value criteria, time of duration, extension of effects, etc., for which certain company acts, including loans by and to the Company, may only be effected by one or more Executive Officers or after prior authorization by the Executive Committee;

102

Table of Contents

· Article 6, § 7º: The Board may decide to create specific committees linked to itself, which shall include one or more of its members, with or without the participation of Executive Officers, Company employees or contracted third-parties with the aim of coordinating or orienting certain corporate processes or operations.

The bylaws state that the director shall be a shareholder (article 6 th), it means that director should hold at least 1 share of the company to take office. Corporate Law set-forth this same requirement until June 24, 2011. Considering that the Corporate Law was amended on such date in order to have this requirement excluded, the bylaws of the Company will probably be amended by the Shareholders in the following shareholders meeting in this regard.

Rights, preferences and restrictions attaching to each class of the shares

Gerdau’s capital stock is divided into common and preferred shares.

· Rights to dividends

All common and preferred shares enjoy the same rights to dividends, which are established by the Company’s bylaws as a minimum mandatory percentage of 30% of net income, with the following adjustments:

(i) the addition to the following amounts:

· amounts arising during the fiscal year from the reversal of previous contingency reserves;

· amounts resulting from the realization, during the fiscal year, of profits that have previously been transferred to the unrealized profit reserve line;

· amounts arising from the realization during the fiscal year of increases in the value of assets, as a result of new valuations, recorded as revaluation reserve.

(ii) the subtraction of amounts assigned during the fiscal year for the constitution of legal reserves, the reserve for contingencies, the unrealized profit reserve and the tax incentive reserve.

For additional information, please see the item Dividend Policy above.

· Voting rights

According to our bylaws, the common shares have voting rights and the preferred shares have no voting rights although the holders of preferred share are entitle to attend to shareholders’ meetings and to participate in the discussions.

Note, however, that the Company’s bylaws state, in Article 19, Paragraph 11, that the preferred shares shall acquire the right to vote if the Company, for three consecutive fiscal years, fails to pay the minimum dividends to which they are entitled, a right that the shares will hold until the first subsequent payment of dividends that the Company makes.

Shareholders representing the majority of:

a) holders of preferred shares without voting rights (or with restricted voting rights) representing 10% of the total capital stock; and

b) holders of at least 15% of the voting capital stocks; shall have the right to elect and remove from office a member and his substitute from the board of directors, in a separate election at the general meeting, being excluded from such election the majority shareholder.

If neither the holders of shares with voting rights nor the holders of preferred shares without voting rights or with restricted voting rights are sufficient to achieve the quorum above, they shall be allowed to aggregate their shares in order to jointly elect a member and his substitute for the board of directors, in this case considering the quorum of 10% of the capital.

Shareholders representing at least one-tenth of the voting capital may also request that the election of directors be subject to cumulative voting, if present this request to the company up to 48 hours prior to the general shareholders meeting.

Notwithstanding the provisions aforementioned, the controlling shareholders shall always have the right to elect the majority of the members of the board of directors of a Brazilian company.

Based upon section 161 §4 th of Corporate Law, the holders of preferred shares without voting rights or with restricted voting rights shall be entitled to elect one member of the board of auditors and his alternate in a separate election. The

103

Table of Contents

minority shareholders shall have the same right, provided that they jointly represent ten per cent or more of the voting shares.

· Rights to the reimbursement of capital

The preferred shares enjoy preference in the reimbursement of capital, up to the value of their respective interest in the capital stock, in the event of the Company’s dissolution, after which the common shares are reimbursed up to the value of their respective fractional participation in the capital stock, with the remaining balance distributed on equal conditions among the holders of the common and preferred shares.

Liability to further capital calls and Shareholders owning a substantial number of shares

There are no specific provisions in the bylaws of liability to further capital calls by the Company or provisions discriminating against any existing or prospective holder of such securities as a result of such shareholder owning a substantial number of shares.

Changes to the rights

The Brazilian Corporate Law states, in its Section 109, that neither the bylaws nor a general meeting may deprive a shareholder of the right:

a) to participate in the corporate profits;

b) to participate in the assets of the corporation in the case of liquidation;

c) to supervise the management of the corporate business as provided for in the Corporate Law;

d) of first refusal in the subscription of shares, founders’ shares convertible into shares, debentures convertible into shares and subscription bonuses, and

e) to withdraw from the corporation in the cases provided for in the Corporate Law.

Furthermore, Section 16, sole paragraph of Corporate Law set forth that, unless expressly provided for, an amendment to that part of the bylaws which regulates the different classes of shares shall require the approval of the shareholders of all shares thereby affected.

On the same hand, Section 136, §1 st of Corporate Law states that any changes in the preferences or rights of the preferred shares, or the creation of a class of shares having priority in relation to the existing preferred shares, unless the change is authorized by our bylaws, would require the approval of the preferred shareholders in a special shareholders meeting, in addition to approval by the majority of the holders of the outstanding voting shares.

Annual general meetings and extraordinary general meetings of shareholders

The call for the annual general meeting and extraordinary general meeting of Gerdau shall be made by a notice published on at least three occasions in the Jornal do Commercio do Rio de Janeiro, Valor Econômico, São Paulo edition, and Diário Oficial do Estado do Rio de Janeiro. The call shall contain, in addition to the place, date and time of the general meeting, the agenda and, in the case of an amendment to the bylaws, an indication of the subject-matter.

The first call of the general meeting shall occur: fifteen (15) days in advance, and the second call eight (8) days in advance.

Apart from the exceptions provided by law, the opening of a general meeting shall occur on first call with the presence of shareholders representing at least one-quarter of the voting capital; and on the second call, with any number.

The investors attending a general meeting shall produce proof of their shareholder status. According to Gerdau’s bylaws, the Company may require, within a period established in the notice of calling, the depositing of proof of ownership of shares, submitted by the financial institution acting as depositary for the same shares, as well as to suspend, for the same period, transfer and stock split services.

A shareholder may be represented at a general meeting by a proxy, appointed less than one year before, who shall be a shareholder, a corporation officer, a lawyer, or a financial institution. A condominium shall be represented by its investment fund officer.

A request for the appointment of a proxy, made by post or by public notice, shall satisfy the following requirements:

(a) contain all information necessary to exercise the requested vote;

104

Table of Contents

(b) entitle the shareholder to vote against a resolution by appointing another proxy to exercise the said vote;

(c) be addressed to all shareholders whose addresses are kept by the corporation.

Subject to the requirements aforementioned, any shareholder whose shares with or without voting rights represent one-half percent or more of the capital shall be entitled to request a list of the addresses of the shareholders

The legal representative of a shareholder shall receive an authroization to attend general meetings.

Limitations on the rights of non-residents and foreign shareholders to own securities

There are no limitations on the rights to own securities by non-residents or foreign shareholder set forth in the Bylaws of Gerdau S.A. The Brazilian Law neither establishes limitation. Note that some procedures shall be observed by the foreign companies for the remittance of funds (see item 10.D, below).

A shareholder resident or domiciled abroad must maintain a representative in Brazil empowered to accept service of process in proceedings brought against him under this Law.

Change in control of the company

Brazilian Corporate law states that the direct or indirect transfer of control of a publicly held corporation can only be effective under the condition that the purchaser agrees to conduct a public offer to acquire the voting shares owned by the remaining shareholders.

Our bylaws attribute to all shares the right to be included in any public offering involving the transfer of control, guaranteeing the same price paid per share with voting rights that are part of the controlling block.

Disclosure of shareholders ownership

With regard to the disclosure of ownership, shareholders hall observe the rule 358 enacted by the Brazilian Exchange Commission, which sets forth that:

“Article 12. The direct or indirect controlling shareholders and the shareholders that vote for members of the Fiscal Board of Directors, as well as any person or company or group of people acting together or representing the same interest that have either direct or indirect participation corresponding to 5% (five percent) or more in type or class of shares representing the capital of a publicly held company, shall send to the company the following information:

Acquisition of Corporación Sidenor, S.A.

On November 15, 2005, the subsidiary Gerdau Hungria Holdings signed, together with two Spanish companies, one a company belonging to the Santander Group, and other composed of the main executives of the administration of the Sidenor Group, as purchasers, and Industria Férricas del Norte Inversiones, S.L., as the seller, a purchase agreement for the acquisition of all the capital stock of Corporación Sidenor, S.A., in Spain.

On January 10, 2006, the Company completed its acquisition of 40% of Corporación Sidenor S.A. (“Sidenor”), a Spanish steel producer with operations in Spain and Brazil. The Santander Group, Spanish financial conglomerate, purchased simultaneously 40% of Sidenor. The acquisition price of 100% of Sidenor consists of a fixed installment of € 443,820 thousand plus a contingent variable installment to be paid only by the Company. The fixed price paid by the Company on January 10, 2006 for its interest of 40% in Sidenor was € 165,828 thousand (R$ 432,577). The Santander Group has the option to sell its interest in Sidenor to the Company 5 years after the purchase at a fixed price with a fixed interest rate, and Sidenor has the right of preference to purchase these shares and also may, at any time during the period of the put option validity require the Santander Group to exercise the put option before the expiration date. On December 23, 2010, Santander and the Company renewed the put option of the participation in Sidenor and the maturity date of the put option became January 10, 2014, and can be exercised in advance on each month of January from 2012 until the maturity date. The put option price became € 208.648 (R$ 464.868 on December 31, 2010), accrued by a fixed

106

Table of Contents

interest rate. The potential commitment of the Company to purchase from the Santander Group its 40% interest in Sidenor was recorded as a non-current liability under “Put options on minority interest”. As a result of the recognition of this potential obligation, the Company has recognized since the acquisition date, an additional interest of 40% of Sidenor as its investment. As of December 31, 2010, such potencial obligation totaled R$ 464.868 (R$ 449.599 as of December 31, 2009)

On December 19, 2008 the subsidiary Gerdau Hungria Holdings indirectly acquired an additional 20% interest in Corporación Sidenor, S.A.. The total amount paid by Gerdau Hungria Holdings was approximately $ 288.0 million (R$ 674.0 million in the acquisition date), drawing on its own funds. As a result of this acquisition, Gerdau Hungria Holdings directly and indirectly holds 60% of Corporación Sidenor’s capital, and Grupo Santander, with which Grupo Gerdau will continue to share control, holding the remaining 40%.

D. EXCHANGE CONTROLS

There are no restrictions on ownership or voting of the Company’s paid-in capital by individuals or legal entities domiciled outside Brazil. The right to convert dividend payments and proceeds from the sale of the Company’s paid-in capital into foreign currency and to remit such amounts outside Brazil is subject to restrictions under foreign investment legislation which generally require, among other things, the prior registration of the relevant investment with the Central Bank.

In Brazil, a mechanism is available to foreign investors interested in trading directly on the BOVESPA. Until March 2000, this mechanism was known as Annex IV Regulations, in reference to the Annex IV of CMN Resolution N. 1,289/87 (“Annex IV Regulations”). Currently, this mechanism is regulated by CMN Resolution N. 2,689/00.

CMN Resolution N. 2,689/00, which took effect on March 31, 2000, establishes rules for foreign investments in Brazilian equities. Such rules allow foreign investors to invest in almost all types of financial asset and to engage in almost all transactions available in the Brazilian financial and capital markets, provided that certain requirements are fulfilled.

Pursuant to CMN Resolution N. 2,689/00, foreign investors are defined as individuals, legal entities, mutual funds and other collective investments resident, domiciled or headquartered abroad. CMN Resolution N. 2,689/00 prohibits the offshore transfer or assignment of title to the securities, except in the cases of (i) corporate reorganization effected abroad by a foreign investor or (ii) inheritance.

Pursuant to CMN Resolution N. 2,689/00, foreign investors must: (i) appoint at least one representative in Brazil with powers to perform actions relating to the foreign investment; (ii) fill in the appropriate foreign investor registration form; (iii) obtain registration as a foreign investor with the CVM; (iv) appoint an authorized custodian in Brazil for its investment and (v) register the foreign investment with the Central Bank. The securities and other financial assets held by the foreign investor pursuant to CMN Resolution N. 2,689/00 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or by the CVM or be registered in registration, clearing and custody systems authorized by the Central Bank or by the CVM. In addition, securities trading are restricted to transactions carried out on exchanges or organized over-the-counter markets licensed by the CVM. All investments made by a foreign investor under CMN Resolution N. 2,689/00 will be subject to electronic registration with the Central Bank.

CMN Resolution N. 1,927/92 of the National Monetary Council, which is the Amended and Restated Annex V to CMN Resolution N. 1,289/87 (“Annex V Regulations”), provides for the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers. Since ADRs have been approved under the Annex V Regulations by the Central Bank and the CVM, the proceeds from the sale of the ADRs by ADR holders outside Brazil are free of Brazilian foreign investment controls and holders of the ADRs will be subject to a more favorable tax treatment. According to CMN Resolution N. 2,689/00, foreign investments registered under Annex V Regulations may be transferred to the new investment system created by CMN Resolution N. 2,689/00 and vice versa, with due regard to the conditions set forth by the Central Bank and by the CVM.

A foreign investment registration has been made in the name of The Bank of New York Mellon, as Depositary for the Preferred ADRs (“Depositary”), and is maintained by Banco Itaú S.A. (“Custodian”) on behalf of the Depositary. Pursuant to the registration, the Custodian and the Depositary are able to convert dividends and other distributions with respect to the Preferred Shares represented by Preferred ADRs into foreign currency and remit the proceeds abroad. Subject to the provisions set forth in Annex V Regulations, holders of preferred ADRs may exchange such ADRs for the underlying Preferred Shares. In this event, such a holder will be entitled to continue to rely on the Depositary’s registration of foreign investment for only five business days after such exchange, after which time, the same holder must seek its own registration with the Central Bank.

The Registered Capital for Preferred Shares that are withdrawn upon surrender of Preferred ADRs will be the U.S. dollar equivalent to (i) the average price of the Preferred Shares on the BOVESPA on the day of withdrawal, or (ii) if no

107

Table of Contents

Preferred Shares were sold on such day, the average price of Preferred Shares that were sold in the fifteen trading sessions immediately preceding the same withdrawal. The U.S. dollar value of the Preferred Shares is determined on the basis of the average Foreign Exchange rates quoted by the Central Bank on the same date (or, if the average price of Preferred Shares is determined under clause (ii) of the preceding sentence, the average of such average quoted rates on the same fifteen dates used to determine the average price of the Preferred Shares). A non-Brazilian holder of Preferred Shares may experience delays in effecting the registration of Registered Capital, which may delay remittances abroad. Such a delay may adversely affect the amount, in U.S. dollars, received by the non-Brazilian holder.

Thereafter, unless the Preferred Shares are held pursuant to CMN Resolution No. 2,689/00 or to Law N. 4,131/62 by a foreign investor, the same holder may not be able to convert into foreign currency and remit the proceeds outside Brazil from the disposal of, or distributions with respect to, such Preferred Shares, and will generally be subject to less favorable Brazilian tax treatment than a holder of Preferred ADRs.

Restrictions on the remittance of foreign capital overseas could hinder or prevent the Custodian, as custodian for the Preferred Shares represented by Preferred ADRs, or holders who have exchanged Preferred ADRs for Preferred Shares, from converting dividends, distributions or the proceeds from any sale of Preferred Shares into U.S. dollars and remitting such U.S. dollars abroad. Holders of Preferred ADRs could be adversely affected by delays in, or refusal to grant any required government approval for conversions of Brazilian currency payments and remittances abroad of the Preferred Shares underlying the Preferred ADRs.

Exchange Rates

Before March 2005, there were two legal foreign exchange markets in Brazil, the commercial market and the floating market. The difference between these two markets was the type of transaction that could be performed through each market.

On March 4, 2005, through CMN Resolution N. 3,265 (revoked and replaced by CMN Resolution N. 3,568, of May 29, 2008), CMN introduced a single foreign exchange market and abolished the legal differences between the referred Commercial and Floating Markets. Among the modifications to foreign exchange market rules is a greater freedom to remit funds abroad through the foreign exchange market. On the other hand, the so-called “CC5-Accounts”, which are bank accounts in reais held in Brazil by foreign entities, may no longer be used to transfer funds on behalf of third parties.

On March 24, 2010, the CMN approved Resolution No. 3,844, adopting a series of measures to consolidate and simplify the Brazilian foreign exchange regulations. These changes are expected to reduce the effective cost of foreign exchange transactions and the related administrative expenses for both the public and private sectors as well as to provide more legal certainty to the parties to such transaction.

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 let the real 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.

The current exchange rates from U.S Dollar to Brazilian Reais are demonstrated in the table of item 3.A, “Exchange rates between the United States Dollar and Brazilian Reais”.

E. TAXATION

The following summary contains a description of the principal Brazilian and U.S. federal income tax consequences of the purchase, ownership and disposition of Common Shares, Preferred Shares and ADRs. It does not purport to be a comprehensive description of all tax considerations that may be relevant to a decision to purchase those securities. In particular, this summary deals only with holders that will hold Common Shares, Preferred Shares or ADRs as capital assets (generally, property held for investment) and does not address the tax treatment of a holder that may be subject to special tax rules, like a bank, an insurance company, a dealer in securities, a person that will hold Common Shares, Preferred Shares or ADRs in a hedging transaction or as a position in a “straddle”, “conversion transaction” or other integrated transaction for tax purposes, a person that has a “functional currency” other than the U.S. dollar, a person liable for alternative minimum tax, a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) or a person that owns or is treated as owning 10% or more of the voting shares of the Company. Each prospective purchaser of a Common Share, Preferred Share or ADR should consult his own tax advisers as to the personal tax consequences of his investment, which may vary for investors in different tax situations. The summary is based upon tax laws of Brazil and the United States and applicable regulations, judicial decisions and administrative pronouncements as in effect on the date hereof. Those authorities are subject to change or new interpretations, possibly with retroactive effect. Although there is no income tax treaty between Brazil and the United States at this time, the tax

108

Table of Contents

authorities of the two countries have had discussions that may culminate in a treaty. No assurance can be given, however, as to whether or when a treaty will enter into force or how it will affect the US holders of Common Shares, Preferred Shares or ADRs. This summary is also based upon the representations of the Depositary (as defined below) and on the assumption that each obligation in the Deposit Agreement relating to the ADRs and any related documents will be performed in accordance with its terms.

Brazilian Tax Considerations

The following discussion summarizes the principal Brazilian tax consequences of the acquisition, ownership and disposition of common shares, preferred shares or ADRs by a holder that is not resident or domiciled in Brazil for purposes of Brazilian taxation, which we refer to as “Non-Resident Holder”.

The following is a general discussion only. It does not specifically address all of the Brazilian tax considerations applicable to any particular Non-Resident Holder. The discussion does not address the effects of any tax treaties or reciprocity of tax treatment entered into by Brazil and other countries. The discussion does not address either any tax consequences under the laws of any state or municipality of Brazil.

Income tax

Dividends

Dividends paid by a Brazilian corporation, such as our company, including stock dividends and other dividends paid to a Non-Resident Holder of common shares, preferred shares or ADRs, are currently not subject to withholding income tax in Brazil to the extent that such dividends are related to profits generated on or after January 1, 1996. Dividends paid from profits generated before January 1, 1996 may be subject to Brazilian withholding income tax at varying rates, according to the tax legislation applicable to each corresponding year.

Interest Attributable to Shareholders’ Equity

Law No. 9,249, dated December 26, 1995, as amended, permits a Brazilian corporation, such as our company, to make distributions to shareholders of interest on shareholders’ equity and to treat such payments as a deductible expense for purposes of calculating Brazilian corporate income tax and social contribution on net profits, as far as the limits described below are observed. For tax purposes, this interest is limited to the daily pro rata variation of the Brazilian long-term interest rate (“TJLP”), as determined by the Central Bank from time to time, and the amount of the deduction may not exceed the greater of:

· 50% of net income (after the deduction of social contribution on net profits and before taking into account the provision for corporate income tax and the amounts attributable to interest on shareholders’ equity) for the period in respect of which the payment is made; and

· 50% of the sum of retained profits and profit reserves as of the date of the beginning of the period in respect of which the payment is made.

Payment of interest to a Non-Resident Holder is subject to withholding income tax at the rate of 15%, or 25% if the Non-Resident Holder is resident or domiciled in a country or location (1) that does not impose income tax or (2) where the maximum income tax rate is lower than 20% or (3) where the laws of that country or location do not allow access to information regarding the shareholding composition of legal entities, their ownership, or the identity of the beneficial owners of earnings attributable to non-residents (“Tax Favorable Jurisdiction”). Please refer to “—Discussion on Low or Nil Tax Jurisdictions, Tax Favorable Jurisdictions and Privileged Tax Regimes” below for a discussion that the concept of Tax Favorable Jurisdiction may be broadened by Law No. 11,727.

Payments of interest on shareholders’ equity may be included, at their net value, as part of any mandatory dividend. To the extent payment of interest on shareholders’ equity is so included, the corporation is required to distribute to shareholders an additional amount to ensure that the net amount received by them, after payment of the applicable withholding income tax, plus the amount of declared dividends, is at least equal to the mandatory dividend.

Capital Gains

According to Law No. 10,833, dated December 29, 2003, gains deriving from the disposition of assets located in Brazil by a Non-Resident Holder, whether to another non-Brazilian resident or to a Brazilian resident may be subject to withholding income tax in Brazil.

109

Table of Contents

With respect to a disposition of common or preferred shares, as they are assets located in Brazil, the Non-Resident Holder will be subject to withholding income tax on the gains assessed, following the rules described below.

Regarding the ADRs, although the matter is not entirely clear, arguably the gains realized by a Non-Resident Holder on the disposition of ADRs are not taxed in Brazil, based on the argument that ADRs are not “assets located in Brazil” for purposes of Article 26 of Law No. 10,833. We cannot assure you, however, that Brazilian tax authorities or Brazilian tax courts will agree with this interpretation. Accordingly, in the event that ADRs are deemed to be “assets located in Brazil” for purposes of Article 26 of Law No. 10,833, gains on a disposition of ADRs by a Non-Resident Holder will be subject to withholding income tax in Brazil, following the rules described below.

As a general rule, gains realized as a result of a disposition of common or preferred shares (or ADRs, in case they are deemed to be “assets located in Brazil”) are the positive difference between the amount realized on the disposition, and the cost of acquisition of the shares disposed of, measured in Reais (without any correction for inflation). There are grounds, however, for maintaining that the gains realized should be calculated taking into consideration the cost of the relevant investments in foreign currency, as so registered with the Central Bank.

The rules related to the levy of withholding income tax on such gains will vary depending on the domicile of the Non-Resident Holder, the type of registration of the investment by the Non-Resident Holder with the Central Bank, and how the disposition is carried out, as described below.

Gains assessed on a disposition of common or preferred shares carried out on the Brazilian stock exchange (which includes transactions carried out on the organized over-the-counter market) are:

· exempt from income tax when assessed by a Non-Resident Holder that (1) has registered its investment in Brazil with the Central Bank under the rules of National Monetary Council Resolution No. 2,689, dated January 26, 2000 (“2,689 Holder”) and (2) is not domiciled or resident in a country or location that does not tax income, or that taxes income at a maximum rate lower than 20% (“Low or Nil Tax Jurisdiction”). Please refer to “—Discussion on Low or Nil Tax Jurisdictions, Tax Favorable Jurisdictions and Privileged Tax Regimes” below for a discussion that the concept of Low or Nil Tax Jurisdiction may be broadened by Law No. 11,727; or

· subject to income tax at a rate of 15% in any other case, including a case of gains assessed by a Non-Resident Holder that is not a 2,689 Holder, and of a Non-Resident Holder that is domiciled or resident in a Low or Nil Tax Jurisdiction. In these cases, a withholding income tax of 0.005% on the sale value will be applicable and can be later offset against income tax due on any capital gain realized on the transaction.

Gains assessed on a disposition of common or preferred shares (or ADRs, in case they are deemed to be “assets located in Brazil”) that is not carried out on a Brazilian stock exchange are subject to income tax at the rate of 15%, or of 25% in the case of a Non-Resident Holder that is domiciled or resident in a Low or Nil Tax Jurisdiction or in a Tax Favorable Jurisdiction. Please refer to “—Discussion on Low or Nil Tax Jurisdictions, Tax Favorable Jurisdictions and Privileged Tax Regimes” below for a discussion that these concepts may be broadened by Law No. 11,727. In the event that these gains are related to transactions conducted on the Brazilian non-organized over-the-counter market with intermediation, the withholding income tax of 0.005% shall also be applicable and can be offset against income tax due on any capital gain realized on the transaction.

In the event of a redemption of common or preferred shares (or ADRs, in case they are deemed to be “assets located in Brazil”) or of a capital reduction by a Brazilian corporation, such as our company, the positive difference between the amount received by the Non-Resident Holder and the acquisition cost of the respective common or preferred shares (or ADRs, in case they are deemed to be “assets located in Brazil”) will be treated as a capital gain derived from a disposition that is not carried out on a Brazilian stock exchange market, and therefore will be subject to withholding income tax at a rate of 15% or up to 25%, as the case may be.

Any exercise of preemptive rights relating to the common or preferred shares or ADRs will not be subject to Brazilian income tax. Gains realized by a Non-Resident Holder on the disposition of preemptive rights relating to common shares, preferred shares or ADRs will be subject to Brazilian income tax according to the same rules described above.

As a Non-Resident Holder of ADRs, you may cancel your ADRs and exchange them for common or preferred shares. Income tax may not be levied on such exchange, as long as the appropriate rules are complied with in connection with the registration of the investment with the Central Bank, and as long as ADRs are not deemed to be “assets located in Brazil”.

The deposit of common or preferred shares by a Non-Resident Holder in exchange for ADRs may trigger Brazilian income tax on the capital gain presumably realized, at a rate of 15%, or of 25% in the case of a Non-Resident

Holder that is domiciled or resident in a Low or Nil Tax Jurisdiction or in a Tax Favorable Jurisdiction. There are grounds to sustain, however, that such transaction should not trigger Brazilian income tax, provided that the appropriate rules are complied with in connection with the registration of the transaction with the Central Bank.

There can be no assurance that the current favorable tax treatment of 2,689 Holders will continue in the future.

Discussion on Low or Nil Tax Jurisdictions, Tax Favorable Jurisdictions, and Privileged Tax Regimes

Law No. 11,727, dated June 24, 2008, with effect as of January 1, 2009, created the concept of “privileged tax regime”, considered as such the tax regime that (1) does not tax income or taxes it at a maximum rate lower than 20%; or (2) grants tax benefits to non-resident entities or individuals (a) without requiring the exercise of a substantial economic activity in the country or location or (b) contingent to the non-exercise of a substantial economic activity in the country or location; or (3) does not tax or taxes at a maximum rate lower than 20%, in particular, income earned outside of the respective country or location; or (4) does not allow access to information related to shareholding composition, ownership of assets and rights, or economic transactions that are carried out (“Privileged Tax Regime”).

The concept of Privileged Tax Regime should only apply to specific types of transactions, including those subject to transfer pricing rules. Rulings issued by Brazilian tax authorities seem to confirm this interpretation. Notwithstanding, one cannot completely disregard the risk of tax authorities trying to argue that the more burdensome tax treatment generally applicable to residents in Low or Nil Tax Jurisdictions and in Tax Favorable Jurisdictions should also apply with regard to non-residents in Privileged Tax Regimes.

Tax on Foreign Exchange Transactions

Brazilian law imposes a Tax on Foreign Exchange Transactions (“IOF/FX”) due on the liquidation of foreign exchange agreements related to the conversion of reais into foreign currency and on the conversion of foreign currency into reais.

Currently, as a general rule, IOF/FX is levied at the rate of 0.38%. There are, however, a number of exceptions to such general rule (as provided by Article 15-A of Decree No. 6,306/07, as amended).

Foreign exchange transactions for the inflow of funds into Brazil in connection with investments made by foreign investors in the Brazilian financial and capital markets are generally subject to IOF/FX at a rate of 6%. Exceptionally, foreign exchange transactions for the inflow of funds in connection with certain types of investments made in those markets are currently subject to IOF/FX at a zero percent rate.

Among others, the following foreign exchange transactions in connection with investments made in the Brazilian financial and capital markets are subject to IOF/FX at a zero percent rate:

(a) foreign exchange transactions for the inflow of funds to be invested in variable/floating rate income investments (such as common shares or preferred shares) at stock exchanges or futures and commodities exchanges, as regulated by the National Monetary Council (e.g. Resolution No. 2,689), except for investments in derivatives that result in predetermined income;

(b) foreign exchange transactions for the inflow of funds for the acquisition of shares in public offerings registered or discharged from registration with the Brazilian Securities Commission, or subscriptions of shares, provided that, in both cases, the issuing companies are registered/listed to trade shares on the stock exchange; and

(c) foreign exchange transactions for the inflow of funds (including simultaneous (symbolic) FX transactions) for the acquisition of quotas of Private Equity Investment Funds (“FIPs”), Emerging Companies Investment Funds (“FIEEs”) and Investment Funds investing in quotas of FIPs and FIEEs, all set up in accordance with Brazilian Securities Commission’s regulations.

(d) foreign exchange transactions for the inflow of funds resulting from the cancellation of depositary receipts, in exchange for shares traded in a Brazilian stock exchange;

(e) foreign exchange transactions for the inflow of funds deriving from a change on the type of registration of the foreign investment, from a “foreign direct investment” to an investment registered under the rules of the National Monetary Council (e.g. Resolution No. 2,689 investment).

Foreign exchange transactions for the outflow of funds in connection with the return of investments made in the Brazilian financial and capital markets are also subject to IOF/FX at a zero percent rate. The same rate applies on the outflow of funds in connection with payments of dividends and interest on shareholders’ equity made by Brazilian companies.

111

Table of Contents

The Brazilian government is permitted to increase the rate of the IOF/FX at any time by up to 25%. However, any increase in rates will only apply to transactions carried out after this increase in rates enters into force.

Tax on Transactions Related to Bonds and Securities

Brazilian law imposes a Tax on Transactions Related to Bonds and Securities (“IOF/Bonds”) due on transactions involving bonds and securities, including those carried out on a Brazilian stock exchange. Currently, IOF/Bonds are levied at the rate of 0% in most transactions involving common or preferred shares. Notwithstanding, IOF/Bonds is levied at the rate of 1.5% on the transfer of shares traded in Brazilian stock exchanges with the specific purpose of enabling the issuance of depositary receipts to be traded outside Brazil. The Brazilian government is allowed to increase the rate of the IOF/Bonds at any time by up to 1.5% per day of the transaction amount. However, any increase in rates may only apply to transactions carried out after this increase in rates enters into force.

Other Brazilian Taxes

There are no specific Brazilian inheritance, gift or succession taxes applicable to the ownership, transfer or disposition of common or preferred shares or ADRs, except for gift and inheritance taxes that may be imposed by Brazilian states. There are no Brazilian stamp, issue, registration, or similar taxes or duties payable by holders of common or preferred shares or ADRs.

United States Tax Considerations

U.S. Federal Income Tax Considerations

The following discussion summarizes the principal U.S. federal income tax considerations relating to the purchase, ownership and disposition of Preferred Shares or Preferred ADRs by a U.S. holder (as defined below) holding such shares or ADRs as capital assets (generally, property held for investment). This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations, administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”) and judicial decisions, all as in effect on the date hereof, and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. This summary does not describe any state, local or non-U.S. tax law considerations, or any aspect of U.S. federal tax law other than income taxation. U.S. holders are urged to consult their own tax advisers regarding such matters.

This summary does not purport to address all material U.S. federal income tax consequences that may be relevant to a U.S. holder of a Preferred Share or Preferred ADR, and does not take into account the specific circumstances of any particular investors, some of which (such as tax-exempt entities, banks or other financial institutions, insurance companies, broker-dealers, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, regulated investment companies, real estate investment trusts, U.S. expatriates, investors liable for the alternative minimum tax, partnerships and other pass-through entities, investors that own or are treated as owning 10% or more of the Company’s voting stock, investors that hold the Preferred Shares or Preferred ADRs as part of a straddle, hedge, conversion or constructive sale transaction or other integrated transaction, and U.S. holders whose functional currency is not the U.S. dollar) may be subject to special tax rules.

As used herein, a “U.S. holder” is a beneficial owner of a Preferred Share or Preferred ADR that is, for U.S. federal income tax purposes, (i) a citizen or resident alien individual of the United States, (ii) a corporation (or an entity taxable as a corporation) created or organized under the laws of the United States, any State thereof or the District of Columbia, (iii) an estate, the income of which is subject to U.S. federal income tax without regard to its source, or (iv) a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (2) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person. For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of a Preferred Share or Preferred ADR that is not a U.S. holder or a partnership.

If a partnership (including for this purpose any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a Preferred Share or Preferred ADR, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. A holder of a Preferred Share or Preferred ADR that is a partnership and partners in that partnership are urged to consult their own tax advisers regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of Preferred Shares or Preferred ADRs.

Nature of Preferred ADRs for U.S. Federal Income Tax Purposes

The following summary assumes that the representations contained in the deposit agreement among us, The Bank of New York Mellon, as depositary, and the holders and beneficial owners from time to time of ADSs issued

112

Table of Contents

thereunder are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. In general, for U.S. federal income tax purposes, a holder of a Preferred ADR will be treated as the owner of the underlying Preferred Shares. Accordingly, except as specifically noted below, the tax consequences discussed below with respect to Preferred ADRs will be the same for Preferred Shares in the Company, and exchanges of Preferred Shares for Preferred ADRs, and Preferred ADRs for Preferred Shares, generally will not be subject to U.S. federal income tax.

For purposes of the following summary, any reference to Preferred Shares shall be understood to also include reference to the Preferred ADRs, unless otherwise noted.

Taxation of Distributions

U.S. holders

In general, subject to the passive foreign investment company (“PFIC”) rules discussed below, a distribution on a Preferred Share will constitute a dividend for U.S. federal income tax purposes to the extent that it is made from the Company’s current or accumulated earnings and profits as determined under U.S. federal income tax principles. If a distribution exceeds the amount of the Company’s current and accumulated earnings and profits, it will be treated as a non-taxable reduction of basis to the extent of the U.S. holder’s tax basis in the Preferred Share on which it is paid, and to the extent it exceeds that basis it will be treated as capital gain. The Company does not intend to calculate its earnings and profits under U.S. federal income tax principles. Therefore, a U.S. holder should expect that a distribution on a Preferred Share generally will be treated as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above. For purposes of this discussion, the term “dividend” means a distribution that constitutes a dividend for U.S. federal income tax purposes.

The gross amount of any dividend on a Preferred Share (which will include the amount of any Brazilian taxes withheld) generally will be subject to U.S. federal income tax as foreign source dividend income and will not be eligible for the corporate dividends received deduction. In the case of a Preferred Share, but not a Preferred ADR, the amount of a dividend paid in Brazilian currency will be its value in U.S. dollars based on the prevailing spot market exchange rate in effect on the day that the U.S. holder receives the dividend. In the case of a dividend received in respect of a Preferred ADR, the amount of a dividend paid in Brazilian currency will be its value in U.S. dollars based on the prevailing spot market exchange rate in effect on the date the Depositary receives it, whether or not the dividend is converted into U.S. dollars. A U.S. holder will have a tax basis in any distributed Brazilian currency equal to its U.S. dollar amount on the date of receipt, and any gain or loss realized on a subsequent conversion or other disposition of the Brazilian currency generally will be treated as U.S. source ordinary income or loss. If dividends paid in Brazilian currency are converted into U.S. dollars on the date they are received by a U.S. holder or the Depositary or its agent, as the case may be, the U.S. holder generally should not be required to recognize foreign currency gain or loss in respect of the dividend income. U.S. holders are urged to consult their own tax advisers regarding the treatment of any foreign currency gain or loss if any Brazilian currency received by the U.S. holder or the Depositary or its agent is not converted into U.S. dollars on the date of receipt.

Subject to certain exceptions for hedged positions, any dividend that a non-corporate U.S. holder receives on a Preferred Share in a taxable year beginning before January 1, 2013 will be subject to a maximum tax rate of 15% if the dividend is a “qualified dividend.” A dividend on a Preferred Share will be a qualified dividend if (i) the Preferred Shares are readily tradable on an established securities market in the United States, (ii) the U.S. holder meets the holding period requirement for the Preferred Share (generally more than 60 days during the 121-day period that begins 60 days before the ex-dividend date), and (iii) the Company was not, in the year prior to the year the dividend was paid, and is not, in the year the dividend is paid, a passive foreign investment company (“PFIC”).

The Preferred ADRs are listed on the New York Stock Exchange and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. Based on existing guidance, it is not entirely clear whether a dividend on a preferred share will be treated as a qualified dividend, because the preferred shares themselves are not listed on a U.S. exchange. As discussed below under “PFIC Rules,” the Company does not believe that it was a PFIC for U.S. federal income tax purposes for its 2011 taxable year, nor does it anticipate being classified as a PFIC in its current taxable year or future taxable years. Given that the determination of PFIC status involves the application of complex tax rules, and that it is based on the nature of the Company’s income and assets from time to time, no assurances can be provided that the Company will not be considered a PFIC for the current (or any past or future) taxable year.

The U.S. Treasury Department has announced its intention to promulgate detailed rules pursuant to which holders of stock of non-U.S. corporations, and intermediaries through whom the stock is held, will be permitted to rely on certifications from issuers to establish that dividends are treated as qualified dividends. Because those detailed procedures have not yet been issued, it is not clear whether the Company will be able to comply with them. Special limitations on foreign tax credits apply to dividends subject to the reduced rate of tax for qualified dividends. U.S.

113

Table of Contents

holders of Preferred Shares are urged to consult their own tax advisers regarding the availability of the reduced dividend tax rate in the light of their own particular circumstances.

Any Brazilian withholding tax will be treated as a foreign income tax eligible for credit against a U.S. holder’s U.S. federal income tax liability, subject to generally applicable limitations under U.S. federal income tax law. For purposes of computing those limitations separately for specific categories of income, a dividend generally will constitute foreign source “passive category income” or, in the case of certain holders, “general category income”. A U.S. holder will be denied a foreign tax credit with respect to Brazilian income tax withheld from dividends received with respect to the underlying Preferred Shares to the extent the U.S. holder has not held the Preferred Shares for at least 16 days of the 30-day period beginning on the date which is 15 days before the ex-dividend date or to the extent the U.S. holder is under an obligation to make related payments with respect to substantially similar or related property. Any days during which a U.S. holder has substantially diminished its risk of loss on the Preferred Shares are not counted toward meeting the 16-day holding period required by the statute. Alternatively, any Brazilian withholding tax may be taken as a deduction against taxable income, provided the U.S. holder takes a deduction and not a credit for all foreign income taxes paid or accrued in the same taxable year. The rules relating to the determination of the foreign tax credit are complex, and U.S. holders are urged to consult with their own tax advisers to determine whether and to what extent they will be entitled to foreign tax credits as well as with respect to the determination of the foreign tax credit limitation.

U.S. holders should be aware that the IRS has expressed concern that parties to whom ADRs are transferred may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. holders of ADRs. Accordingly, the discussion above regarding the credibility of Brazilian withholding taxes could be affected by future actions that may be taken by the IRS.

Non-U.S. holders

A dividend paid to a non-U.S. holder on a Preferred Share will not be subject to U.S. federal income tax unless the dividend is effectively connected with the conduct of trade or business by the non-U.S. holder within the United States (and, if an applicable income tax treaty so provides, is attributable to a permanent establishment or fixed base the non-U.S. holder maintains in the United States). A non-U.S. holder generally will be subject to tax on an effectively connected dividend in the same manner as a U.S. holder. A corporate non-U.S. holder may also be subject under certain circumstances to an additional “branch profits tax,” the rate of which may be reduced pursuant to an applicable income tax treaty.

Taxation of Capital Gains

U.S. holders

Subject to the PFIC rules discussed below, on a sale or other taxable disposition of a Preferred Share, a U.S. holder will recognize capital gain or loss in an amount equal to the difference between the U.S. holder’s adjusted basis in the Preferred Share and the amount realized on the sale or other taxable disposition, each determined in U.S. dollars. Such capital gain or loss will be long-term capital gain or loss if at the time of the sale or other taxable disposition the Preferred Share has been held for more than one year. In general, any adjusted net capital gain of a non-corporate U.S. holder in a taxable year beginning before January 1, 2013 is subject to a maximum tax rate of 15%. In subsequent years, the maximum tax rate on the net capital gain of a non-corporate U.S. holder may be higher. The deductibility of capital losses is subject to limitations.

Any gain a U.S. holder recognizes generally will be U.S. source income for U.S. foreign tax credit purposes, and, subject to certain exceptions, any loss will generally be a U.S. source loss. If a Brazilian tax is withheld on a sale or other disposition of a Preferred Share, the amount realized will include the gross amount of the proceeds of that sale or other disposition before deduction of the Brazilian tax. The generally applicable limitations under U.S. federal income tax law on crediting foreign income taxes generally precludes a U.S. holder from obtaining a foreign tax credit for any Brazilian income tax withheld on a sale of a Preferred Share. Alternatively, any Brazilian withholding tax may be taken as a deduction against taxable income, provided the U.S. holder takes a deduction and not a credit for all foreign income taxes paid or accrued in the same taxable year. The rules relating to the determination of the foreign tax credit are complex, and U.S. holders are urged to consult with their own tax advisers regarding the application of such rules.

Non-U.S. holders

A non-U.S. holder will not be subject to U.S. federal income tax on a gain recognized on a sale or other disposition of a Preferred Share unless (i) the gain is effectively connected with the conduct of trade or business by the non-U.S. holder within the United States (and, if an applicable income tax treaty so provides, is attributable to a permanent establishment or fixed base the non-U.S. holder maintains in the United States), or (ii) in the case of a non-U.S. holder who is an individual, the holder is present in the United States for 183 or more days in the taxable year of the sale or other taxable disposition and certain other conditions apply. Any effectively connected gain of a corporate non-

114

Table of Contents

U.S. holder may also be subject under certain circumstances to an additional “branch profits tax,” the rate of which may be reduced pursuant to an applicable income tax treaty.

PFIC Rules

A special set of U.S. federal income tax rules applies to a foreign corporation that is a PFIC for U.S. federal income tax purposes. Based on the Company’s audited financial statements and relevant market and shareholder data, as well as the Company’s current and projected income, assets and activities, the Company believes it was not a PFIC for U.S. federal income tax purposes for its 2011 taxable year, nor does it anticipate being classified as a PFIC in its current taxable year or future taxable years. However, because the determination of whether the Company is a PFIC is based upon the composition of its income and assets from time to time, and because there are uncertainties in the application of the relevant rules, it is possible that the Company will become a PFIC in a future taxable year (and no assurance can be provided that the Company will not be considered a PFIC for its current (or any past) taxable year).

If the Preferred Shares were shares of a PFIC for any taxable year, U.S. holders (including certain indirect U.S. holders) may be subject to adverse tax consequences, including the possible imposition of ordinary income treatment for gains or “excess distributions” (generally a distribution in excess of 125% of the average distributions received during the past three years or, if shorter, the U.S. holder’s holding period) that would otherwise be taxed as capital gains or dividends, along with an interest charge on gains or “excess distributions” allocable to prior years in the U.S. holder’s holding period during which the Company was determined to be a PFIC. If the Company is deemed to be a PFIC for a taxable year, dividends on a Preferred Share would not constitute “qualified dividends” subject to preferential rates of U.S. federal income taxation. In addition, if the Company is deemed to be a PFIC for a taxable year, U.S. holders would be subject to increased reporting requirements. U.S. holders are urged to consult their own tax advisers regarding the application of the PFIC rules.

Information Reporting and Backup Withholding

Under U.S. federal income tax law and the Treasury regulations, certain categories of U.S. holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, recently enacted legislation generally imposes new U.S. return disclosure obligations (and related penalties) on U.S. holders that hold certain specified foreign financial assets in excess of $50,000. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U. S. holders may be subject to these reporting requirements unless their Preferred Shares are held in an account at a domestic financial institution. Penalties for failure to file certain of these information returns are substantial. U.S. holders should consult with their own tax advisers regarding the requirements of filing information returns, and, if applicable, filing obligations relating to the PFIC rules.

Dividends paid on, and proceeds from the sale or other taxable disposition of, a Preferred Share to a U.S. holder generally may be subject to information reporting requirements and may be subject to backup withholding (currently at the rate of 28%) unless the U.S. holder provides an accurate taxpayer identification number or otherwise demonstrates that it is exempt. The amount of any backup withholding collected from a payment to a U.S. holder will be allowed as a credit against the U.S. holder’s U.S. federal income tax liability and may entitle the U.S. holder to a refund, provided that certain required information is timely submitted to the IRS. A non-U.S. holder generally will be exempt from these information reporting requirements and backup withholding tax but may be required to comply with certain certification and identification procedures in order to establish its eligibility for exemption.

I. SUBSIDIARY INFORMATION

Not applicable.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES REGARDING MARKET RISK

Gerdau is exposed to various market risks, mainly variations in exchange rates and interest rate volatility. The company enters into derivatives and other financial instruments to manage and reduce the impact of fluctuations in interest rates and in the exchange rates. Gerdau has established policies and procedures for risk assessment and the approval, reporting and monitoring of its derivative financial activities. Gerdau does not carry out leveraged operations involving derivative instruments. The use of derivatives is limited to managing the foreign-exchange exposure of the cash flow generated by the Company’s operations, as well as interest rate swaps.

Foreign Exchange Rate Risk

This risk is related to the possibility of fluctuations in exchange rates affecting financial expenses (or income) and the liability (or asset) balance of contracts denominated in foreign currency. The Company assesses its exposure to the exchange rate by subtracting its liabilities from its assets in dollars, having in this way the net exchange rate exposure basis, which is the basis subject to effects in a change in the foreign currency. Therefore, along with accounts receivable originated from exports and investments abroad that in economic terms result in a natural hedge, the Company assesses using hedge operation, more commonly swap operations, if the Company has more liabilities in dollars than assets.

Gerdau is exposed to fluctuations in the exchange rate of several different currencies movements since substantially all of its revenues generated outside its subsidiaries in the United States, are in the local currency of the respective subsidiaries, mainly in Brazilian reais, while a significant portion of its debt is denominated in or indexed to U.S. dollar.

The Company’s estimate of the fair value of its financial instruments, including long-term debt, approximates to their recognized book value.

Foreign currency sensitivity analysis: the Company is exposed to variations in foreign currency, especially in loans and financing. The sensitivity analysis made by the Company considers the effects of an increase or a reduction of 5% between the Brazilian real and the foreign currencies on such outstanding loans and financing on the date of the Consolidated Interim Financial Statements. As of December 31, 2010, the Company is mainly exposed to variations between Brazilian real and US Dollar, since the loans taken by the other than Brazilian subsidiaries of the Company are mainly in the same currency of the functional currency of each subsidiary, and because of this aspect, these loans do not expose the Company to variations in foreign currency. The impact calculated considering such variation in the foreign exchange rate totals R$ 51,594 as of December 31, 2011 (R$ 88,535 as of December 31, 2010) and represents an income if an appreciation of the Brazilian real against the US Dollar occurs or an expense in the case of a depreciation of the Brazilian real against the US Dollar. The Company believes that the Dollar depreciation against Real for 2012 will be 5%.

The net amounts related to accounts receivable and accounts payable in foreign currency do not present relevant risks related to exchange rates fluctuation.

Interest rate risk

This risk arises from the possibility of losses (or gains) due to fluctuations in interest rates applied to the Company’s assets (investments) or liabilities in the market. To minimize possible impacts from interest rate fluctuations, the Company adopts a diversification policy, alternating from variable (such as LIBOR and CDI) to fixed rates when contracting debts and hedges and periodically renegotiating contracts to adjust them to market.

From time to time, the Company has entered into interest rate swaps in order to reduce interest rate risk and interest expense. The Company makes only limited use of derivative instruments and only for non-speculative purposes, in order to manage well-defined interest rate risks arising during the normal course of its business.

116

Table of Contents

Interest rate sensitivity analysis: the Company is exposed to interest rate risks in its loans and financing and debentures. The sensitivity analysis made by the Company considers the effects of an increase or reduction of 0.1% on outstanding loans and financing and debentures on the date of the Consolidated Interim Financial Statements. The impact calculated considering this variation in the interest rate totals R$ 74,285 as of December 31, 2011 (R$ 77,516 as of December 31, 2010) and would impact the Financial expenses account in the Consolidated Statements of Income.

Price risk of commodities

This risk is related to the possibility of changes in prices of the products sold by the Company or in prices of raw materials and other inputs used in the productive process. Since the subsidiaries operate in a commodity market, their sales revenues and cost of sales may be affected by changes in the international prices of their products or materials. In order to minimize this risk, the subsidiaries constantly monitor the price variations in the domestic and international markets.

Credit risk

This risk arises from the possibility of the subsidiaries not receiving amounts arising from sales to customers or investments made with financial institutions. In order to minimize this risk, the subsidiaries adopt the procedure of analyzing in detail the financial position of their customers, establishing a credit limit and constantly monitoring their balances. In relation to cash investments, the Company invests solely in financial institutions with low credit risk, as assessed by rating agencies. In addition, each financial institution has a maximum limit for investment, determined by the Company’s Credit Committee.

Capital management risk

This risk comes from the Company’s choice in adopting a financing structure for its operations. The Company manages its capital structure, which consists of a ratio between the financial debts and its own capital (Shareholders’ Equity, retained earnings, and profit reserves) based on internal policies and benchmarks. The BSC (Balance Scorecard) methodology was used in the last 5 years to elaborate strategic maps with objectives and indicators of the main processes. The KPI’s (Key Performance Indicators) related to the objective “Capital Structure Management” are: WACC (Weighted Average Cost of Capital), Total Indebtedness/EBITDA, Interest Coverage Ratio, and Indebtedness/Shareholders’ Equity Ratio. The Total Debt is composed of loans and financing (see Note 13 — Consolidated Financial Statements) and debentures (see Note 14 - Consolidated Financial Statements). The Company can change its capital structure depending on economic-financial conditions in order to optimize its financial leverage and its debt management.

ITEM 15. CONTROLS AND PROCEDURES

Disclosure control and procedures

The Company has carried out an evaluation of the effectiveness of the design and operations to assurance the objectives achievement of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Security Exchange Act of 1934) under the supervision of its management, which is responsible for the management of the internal controls, and includes its Chief Executive Officer and Chief Financial Officer.

This Committee oversees and reviews all materials for which there is a legal disclosure requirement, together with all data required to support the documents mentioned above. This committee meets at regular intervals in order to review all data.

No changes in the Company’s internal controls over Financial Reporting occurred during the period covered by this report that materially affected or are reasonably likely to materially affect the Company’s internal controls over financial reporting.

Management’s Annual Report on Internal Controls over Financial Reporting

The management of Gerdau S.A. is responsible for the implementation, effectiveness and maintenance of an effective system of internal control over the Consolidated Financial Statements as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control is a process designed to provide reasonable assurance regarding the reliability and the preparation of the Consolidated Financial Statements for external purposes in accordance with generally accepted accounting principles.

Management assessed the effectiveness of the Company’s internal control over Consolidated Financial Statements as of December 31, 2011, based on the criteria established in “Internal Control — Integrated Framework”, issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on that assessment, Management concluded that, as of December 31, 2011, the Company’s internal control over financial reporting is effective.

The Company’s independent registered public accounting firm during 2011, Deloitte Touche Tohmatsu Auditores Independentes, has issued an audit report on the effectiveness of the Company’s internal control over the financial statements. That report is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Gerdau S.A.

Rio de Janeiro, Brazil

We have audited the internal control over financial reporting of Gerdau S.A. and subsidiaries (the “Company”) as of December 31, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company´s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company´s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Table of Contents

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2011 of the Company and our report dated March 27, 2012 expressed an unqualified opinion on those consolidated financial statements.

ITEM 16. [RESERVED]

ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT

The Board of Directors has determined that Bolívar Charneski, a member of its Board of Auditors, is a “financial expert” and independent within the meaning of the SEC rules applicable to disclosure of such expertise.

ITEM 16B. CODE OF ETHICS

In the last fiscal year, Gerdau S.A. integrated its three previous codes - Gerdau Ethical Guidelines, Gerdau Ameristeel’s Code of Ethics and Business Conduct and Gerdau Ameristeel Code of Ethics for Senior Executives — into one single Code of Ethics applicable to all of Gerdau’s business units around the world.

The provisions of the Code are thus binding on Gerdau’s Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, and other persons performing similar functions.

The new Code of Ethics is focused on the ethics and compliance issues most important to a publicly-held company and meets all applicable legal requirements.

The code is organized according to the Company’s values which are: (a)Be the Customer’s choice, (b)Safety above all, (c)Respected, engaged and fulfilled Employees, (d)Pursuing excellence with simplicity, (e)Focus on results, (f)Integrity with all stakeholders and, (g) Economic, social and environmental sustainability.

The code instructs all employees to follow a number of steps when reporting violations. The company has implemented an Ethics Helpline to which all employees may refer in the case of any violations of the code.

The purpose and the contents of this new Code of Ethics have been made public to all employees and have been the object of in-company training.

In the same manner as the three previous codes mentioned in the first paragraph, this new Code of Ethics meets the definition contemplated by applicable SEC and New York Stock Exchange rules, covering wrongdoing related to business conduct, conflicts of interest, disclosure in reports and other documents, as well as compliance with legislation.

The Gerdau Code of Ethics is filed herewith as exhibit 11.01 and also may be accessed through our Internet website (www.gerdau.com).

The Company did not grant any waiver from the Code provisions in the last fiscal year.

ITEM 16C. PRINCIPAL ACCOUNTANT FEES AND SERVICES

The following table provides information on fees billed to Gerdau for professional services rendered by the external auditors responsible for auditing the financial statements included in this Annual Report (in thousands of Brazilian Reais) which were Deloitte Touche Tohmatsu Auditores Independentes for the year ended December 31, 2011 and December 31, 2010:

120

Table of Contents

|  | 2011 |  | 2010 |
Audit fees |  | 10,711 |  | 8,999 |
Audit-related fees |  | 133 |  | 117 |
All other fees |  | 82 |  | 209 |
Total |  | 10,926 |  | 9,325 |

Audit fees are related to professional services rendered in the auditing of Gerdau’s consolidated financial statements, quarterly reviews of Gerdau’s consolidated financial statements and statutory audits and interim reviews of certain of the Company’s subsidiaries and affiliates as required by the appropriate legislation. Those amounts also include fees related to the audit of internal controls over financial reporting of Gerdau and of Gerdau Ameristeel.

Audit-related fees are for assurance and related services, such as due diligence services traditionally performed by an external auditor related to acquisitions, as well as consulting on accounting standards and transactions.

Other fees are related to services provided to subsidiaries in Europe (relating to tax compliance) and to subsidiaries in North America (tax services).

ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES

On April 28, 2005, the Company elected its Board of Auditors duly adapted to ensure compliance with the Sarbanes-Oxley Act requirements and exemptions from the listing standards. The Board of Auditors (“Conselho Fiscal”) has been operating in accordance with Brazilian Corporate Law 6,404/76, since April 2000. The customary role of this board is to monitor and verify the actions of company directors and executive officers and the compliance with their legal duties, providing opinions and official statements on the annual management report and the proposals of members of the Board of Directors, denouncing errors or fraud, calling meetings whenever necessary and analyzing financial statements. In establishing a permanent Board of Auditors, the Company has availed itself of paragraph (c)(3) of Rule 10A-3 of the U.S. Securities Exchange Act of 1934, as amended, which provides a general exemption from the audit committee requirements for a foreign private issuer (such as the Company) with a board of auditors, subject to certain requirements which continue to be applicable under Rule 10A-3.

NYSE rules require that listed companies have an audit committee that (i) is composed of a minimum of three independent directors who are all financially literate, (ii) meets the SEC rules regarding audit committees for listed companies, (iii) has at least one member who has accounting or financial management expertise and (iv) is governed by a written charter addressing the committee’s required purpose and detailing its required responsibilities. However, as a foreign private issuer, the Company needs only to comply with the requirement that the audit committee, or Board of Auditors in its case, meet the SEC rules regarding audit committees for listed companies. The Brazilian Corporate Law requires companies to have a non-permanent Board of Auditors composed of three to five members who are elected by the shareholders at the Ordinary General Meeting of Shareholders. The Board of Auditors operates independently from management and from a company’s external auditors. Its main function is to monitor the activities of the management of the company, examine the financial statements of each fiscal year and provide a formal report to its shareholders.

The Company has a permanent “Conselho Fiscal” that consists of three up to five members and three up to five alternates and which has ordinary meetings every two months. The members of the Gerdau S.A.’s “Conselho Fiscal” are all financially literate and one member has accounting expertise that qualifies him as an audit committee financial expert. Gerdau S.A. believes that its Board of Auditors, as modified, meets the requirements for the exemption available to foreign private issuers under the SEC rules regarding audit committees of listed companies. In addition, the Board of Auditors operates under a written charter that is in the process of being amended and which the Gerdau S.A. believes meets the NYSE’s requirements for audit committee charters. The Board of Auditors is not the equivalent of, or wholly comparable to, a U.S. audit committee. Among other differences, it is not required to meet the standards of “independence” established in Rule 10A-3 and is not fully empowered to act on matters that are required by Rule 10A-3 to be within the scope of an audit committee’s authority. Nonetheless, with the duties that have been provided to the Board of Auditors to the extent permitted by Brazilian law, Gerdau S.A. believes that its current corporate governance system, taken as a whole, including the ability of the Board of Auditors to consult internal and external experts, is fully equivalent to a system having an audit committee functioning as a committee of its Board of Directors. For a further discussion of its Board of Auditors, see “Item 6C. Board Practices — Board of Auditors”.

The Board of Auditors members are elected at the Ordinary Shareholders’ Meeting for one-year terms. They are eligible for reelection. In Gerdau S.A. the Board of Auditors consists of three members and three alternates. In Metalúrgica Gerdau S.A. the minority and preferred shareholders elected two of the current effective five members. As required by Brazilian law, members of the Board of Auditors must have college graduation or held office for at least

121

three years as business administrators or as members of boards of auditors. The Board of Auditors, at the request of any of its members, may ask the external auditors to provide explanations or information and to investigate specific facts.

ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT.

In accordance with Rule 549/08 of the CVM (Brazilian Securities and Exchange Commission) that requires auditor rotation in the ordinary course of 5 years, PricewaterhouseCoopers Auditores Independentes (“PwC”) replaced Deloitte Touche Tohmatsu Auditores Independentes (“Deloitte”) as our independent registered public accounting firm for the fiscal years starting January 1, 2012. The change in auditors was made pursuant to this Rule that limits the consecutive terms that certain service providers may serve. Because of the limitations set forth in this Rule, we did not seek to renew Deloitte’s contract when it expired and Deloitte could not attempt to stand for reelection. The replacement of Deloitte by PwC was approved by our Board of Directors and Audit Committee on December 9, 2011. Deloitte is engaged as our auditor for the fiscal year ended December 31, 2011 until the filling of this Form 20-F with the U.S. Securities and Exchange Commission.

Deloitte audited our financial statements for the fiscal years ended December 31, 2011 and December 31, 2010. None of the reports of Deloitte on our financial statements for either of such fiscal years contained an adverse opinion or disclaimer of opinion, or was qualified or modified as to uncertainty, audit scope or accounting principles. During these years and until its contract expired, there were no disagreements with Deloitte, whether or not resolved, on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Deloitte’s satisfaction, would have caused it to make reference to the subject matter of the disagreement in connection with any reports it would have issued, and there were no “reportable events” as that term is defined in Item 16F(a)(1)(v) of Form 20-F and Item 304(a)(1)(v) of Regulation S-K. Deloitte did not audit, or performed a review of, any of our financial statements for any period subsequent to December 31, 2011.

We have provided Deloitte with a copy of the foregoing disclosure, and have requested that they furnish us with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with such disclosure. We are including as Exhibit 15.1 to this Form 20-F a copy of the letter from Deloitte as required by Item 16F(a)(3) of Form 20-F.

During the fiscal years ended December 31, 2011 and December 31, 2010, we did not consult with PwC regarding the application of accounting principles to a specific completed or contemplated transaction or regarding the type of audit opinion that might be rendered by PwC on our financial statements. Further, PwC did not provide any written or oral advice that was an important factor considered by us in reaching a decision as to any such accounting, auditing or financial reporting or any matter being the subject of disagreement or “reportable event” or any other matter as defined in Item 16F(a)(2) of Form 20-F and Item 304(a)(2) of Regulation S-K.

ITEM 16G. CORPORATE GOVERNANCE

Under the Corporate Governance Rules of the New York Stock Exchange, currently in effect, Gerdau S.A. is required to disclose any significant ways in which its corporate governance practices differ from those required to be followed by domestic companies under NYSE listing standard. These significant differences are summarized below.

The Company is permitted to follow practice in Brazil in lieu of the provisions of the Corporate Governance Rules, except that are required to avail itself of an appropriate exemption to the requirement to have a qualifying audit committee under Section 303A.06 of the Rules and its Chief Executive Officer is obligated, under Section 303A.12(b), to promptly notify the NYSE in writing after any of its executive officers becomes aware of any material non-compliance with any applicable provisions of the Corporate Governance Rules.

Majority of Independent Directors: Under NYSE Rule 303A.01 domestic listed companies must have a majority of independent directors. The Company does not have a similar requirement under Brazilian practice and does not have a majority of independent directors serving on its board of directors, even though the majority of the members are non-management directors.

125

Table of Contents

Separate meetings of non-management directors: Under NYSE Rule 303A.03, the non-management directors of each domestic listed company must meet at regularly scheduled executive sessions without management. Gerdau does not have a similar requirement under Brazilian practice, but non-management directors meet separately once a year to assess management performance.

Nominating/corporate governance committee: Under NYSE Rule 303A.04, a domestic listed company must have a nominating/corporate governance committee composed entirely of independent directors. While the Company is not required to have such a committee under Brazilian law, it has a Corporate Governance Committee that is composed by a majority of independent directors. The purpose of this Committee is to provide its views to the board in respect of the best practices in Corporate Governance.

Compensation Committee: Under NYSE Rule 303A.05, a domestic listed company must have a compensation committee composed entirely of independent directors. Gerdau is not required to have such a committee under Brazilian practice. It has established a Remuneration and Succession Committee to advise the full Board on employee and executive compensation and recruitment, incentive-compensation plans and related matters, but such committee does not have a separate charter and is composed by a majority of independent directors. Its full Board of Directors otherwise is directly responsible for employee and executive compensation and recruitment, incentive-compensation and related matters.

Audit Committee: Under NYSE Rule 303A.06 and the requirements of Rule 10A-3 of the Securities and Exchange Commission, domestic listed companies are required to have an audit committee consisting entirely of independent directors that otherwise complies with Rule 10A-3. In addition, the audit committee must have a written charter that addresses the matters outlined in NYSE Rule 303.A.06(c), has an internal audit function and otherwise fulfills the requirements of the NYSE and Rule 10A-3. There is no requirement for an audit committee under Brazilian law and there are features of Brazilian law that require adaptation of the independent audit committee rule to local practice, as permitted by NYSE Rule 303A.06 and Rule 10A-3. Gerdau has a board of auditors (conselho fiscal) that currently performs certain of the functions prescribed for the audit committee, although the scope of its duties is not entirely compatible with the requirements of U.S. law and the NYSE rules. The company has adapted its corporate governance practices and the functions of the board of auditors (with certain limitations due to Brazilian corporate law that qualify for an exemption as authorized by the SEC) to assure compliance with the requirements of the NYSE Rule and Rule 10A-3. See Item 6C.—“Board Practices—Board of Auditors” and Item 16D.—“Exemption from the Listing Standards for Audit Committees.”

Equity Compensation Plans: Under NYSE Rule 303A.08, shareholders must be given the opportunity to vote on all equity-compensation plans and material revisions thereto, with certain limited exemptions as described in the Rule. The General Shareholders’ meeting held on April 30, 2003 approved the establishment by the Board of a stock option plan for executives. Any material changes to such plan, or a new or different plan if established, would require the favorable vote of holders of the common shares of the Company. Holders of preferred shares, including holders of Gerdau’s ADSs, would not have the opportunity to vote on such a plan or any revisions thereto.

Corporate governance guidelines: Under NYSE Rule 303A.09, domestic listed companies must adopt and disclose their corporate governance guidelines. Gerdau does not have a similar requirement under Brazilian law, although it does establish operating principles for its executive management and it observes the requirements of Instruction 358 of the Brazilian Securities Commission (CVM) concerning trading in its shares. In addition, it has adhered to the Level I listing standards of the BOVESPA.

Code of Business Conduct and Ethics: Under NYSE Rule 303A.10, domestic listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees and promptly disclose any waivers of the code for directors or executive officers. Gerdau has a similar requirement under Brazilian law and it has adopted a code of ethics that applies to its directors, officers and employees. For more information regarding the Code of Ethics please see item 16B. Code of Ethics.

Further information concerning Gerdau’s corporate governance practices and applicable Brazilian law is available on the Company’s website, in its submissions to the U.S. Securities and Exchange Commission. The Company has also voluntarily adhered to the Level I listing standards of the Sao Paulo Stock Exchange (BOVESPA) on which its shares are traded, which impose heightened standards of disclosure, transparency and corporate governance on Gerdau.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Gerdau S.A.

Rio de Janeiro, Brazil

We have audited the accompanying consolidated balance sheets of Gerdau S.A. and subsidiaries (the “Company”) as of December 31, 2011 and 2010, and the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Gerdau S.A. and subsidiaries as of December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board — IASB.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 27, 2012 expressed an unqualified opinion on the Company’s internal control over financial reporting.

GERDAU S.A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2011, 2010 and 2009

(in thousands of Brazilian reais — R$, unless otherwise stated)

NOTE 1 - GENERAL INFORMATION

Gerdau S.A. is a publicly traded corporation (sociedade anônima) with its corporate domicile in the city of Rio de Janeiro, Brazil. Gerdau S.A and subsidiaries (collectively referred to as the “Company”) are engaged in the production and sale of steel products from plants located in Brazil, Argentina, Chile, Colombia, Guatemala, Mexico, Peru, Dominican Republic, Uruguay, Venezuela, United States, Canada, Spain, and India. The Company started its path of expansion over a century ago and it is one of the main players in the process of consolidating the global steel industry. The Company produces common long steel, special steels and flat steels, mainly through the production process in electric furnaces using scrap and pig iron that are mostly purchased in the region in which each plant operates (mini-mill concept), and also produces steel from iron ore (through blast furnaces and direct reduction). Its products serve the sectors of civil construction, industry, automotive and agriculture.

The Consolidated Financial Statements of Gerdau S.A and subsidiaries were approved by the Board of Directors on March 27, 2012.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING PRACTICES

2.1 - Basis of Presentation

The Company’s Consolidated Financial Statements have been prepared in accordance with the International Financial Reporting Standards (IFRS) issued by International Accounting Standards Board (IASB).

The preparation of the Consolidated Financial Statements in accordance with IFRS requires Management to make accounting estimates. The areas that involve judgment or use of estimates relevant to the Consolidated Financial Statements are stated in Note 2.18. The Consolidated Financial Statements have been prepared using the historical cost as its basis, except for the valuation of certain financial instruments and foresting/reforesting assets, which are measured at fair value.

The Company adopted all applicable standards, revision of standards and interpretations issued by IASB and the IFRS Interpretations Committee and that were effective on December 31, 2011.

2.2 — Translation of Foreign Currency Balances

a) Functional and Reporting Currency

The Financial Statements of each subsidiary included in the Company’s consolidation and those used as a basis for accounting for equity investments are prepared using the functional currency of each entity. The functional currency of an entity is the currency of the primary economic environment where it operates. By defining the functional currency of each subsidiary, Management considered which currency significantly influences the sales price of its products and services and the currency in which most of the cost of its production inputs is paid or incurred.

b) Transactions and Balances

For purposes of the Consolidated Financial Statements, the balances of each subsidiary of the Company are converted into Brazilian reais, which is the presentation currency of the Consolidated Financial Statements.

In the preparation of the financial statements of each subsidiary of the Company, transactions in foreign currency, or any other currency than the functional currency of each company, are recorded according to the exchange rates prevailing at the time of each transaction. At the end of each period, monetary items in foreign currencies are converted at the

F-9

GERDAU S.A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2011, 2010 and 2009

(in thousands of Brazilian reais — R$, unless otherwise stated)

rates prevailing at year end. The non-monetary items measured at fair value determined in foreign currency are converted at the rates prevailing on the date that the fair value was determined. The non-monetary items that are measured at historical cost in a foreign currency must be converted using the prevailing rate in the transaction date.

For presentation of the consolidated financial statements purposes, assets and liabilities of operations abroad are translated into reais using the exchange rates prevailing at year end. The income statement accounts are translated at average exchange rates for the period unless the exchange rates have fluctuated significantly over the period, in which case, we use exchange rates for the dates of transactions. The exchange differences resulting from these conversions, if any, are recorded in comprehensive income and accumulated in equity, being assigned to the non-controlling interests as appropriate.

When there is a write off for an operation abroad (full write off of participation in a foreign operation, loss of control over an investee or a jointly controlled entity that have operations abroad, or loss of significant influence over an affiliate that has an operation in abroad), the accumulated amount of exchange variance, regarding this operation, recorded in equity is reclassified to profit or loss.

c) Group Companies

The results of operations and financial position of all subsidiaries, except the subsidiary located in Venezuela, included in the consolidated financial statements and equity investments with functional currencies different from the reporting currency are translated into the reporting currency as follows:

i) Assets and liabilities balances are translated at the exchange rate in effect at the date of the Consolidated Financial Statements;

ii) Income and expenses are translated using the average monthly exchange rates for the year; and

iii) Translation gains and losses resulting from the above methodology are recognized in Equity, in the Statement of Comprehensive Income, in the account named “Cumulative translation adjustment”.

d) Hyperinflation in Venezuela

As from 2009, Venezuela started to be considered an hyperinflationary economy and in accordance with the standard IAS 29 and IFRIC 7, the financial statements of the subsidiary located in this country have been adjusted so that the amounts are stated in the measurement currency unit of the end of the year, which considers the effects measured by the IPC - Índice de Preços ao Consumidor (Consumer Price Index) of Venezuela, which recorded an accumulated index of 212.5%, since the date of acquisition of the subsidiary in Venezuela by the Company in June 2007, and 70.2% in 2011. The effects of inflation in 2011 were presented in the consolidated statements of income.

For purposes of translation of the subsidiary in Venezuela’s accounting balances to the presentation currency used in its Consolidated Financial Statements, the Company applied the requirements established by the standard IAS 21, where assets, liabilities, income and expenses balances are translated at the exchange rate prevailing at the date of the Consolidated Financial Statements, being all exchange rate differences from translation being recognized in ‘Equity’, and in the Consolidated Statement of Comprehensive Income, in the account named ‘Cumulative translation adjustment’.

2.3 - Financial Assets

a) Cash and Cash Equivalents

Cash and cash equivalents include cash, bank accounts and highly liquid investments with original maturities of 90 days or less and low risk of variation in market value and are stated at cost plus accrued interest.

(in thousands of Brazilian reais — R$, unless otherwise stated)

b) Short and Long-term Investments

Short and long-term investments are classified into the following categories: held to maturity securities, available for sale securities, and securities reported at fair value through profit and loss with gains and losses included in profit or loss (trading securities). The classification depends on the purpose for which the investment was acquired. When the investment purpose is to earn short-term gains, they are classified as trading securities. When the purpose is to hold the investment until maturity, they are classified as held to maturity securities, provided that Management has the positive intent and financial condition to hold the investment until maturity. When the purpose is none of the other options above, investments are classified as available for sale securities.

When applicable, transaction costs directly related to the acquisition of a financial asset are added to the amount initially recognized, except for trading securities which are categorized as fair value through profit or loss.

Held to maturity securities are recognized at amortized cost and are reported at acquisition cost plus interest, monetary adjustments, and exchange variation, less impairment losses, when applicable, incurred up to the Consolidated Financial Statements date.

Trading securities are stated at fair value. Interest, monetary adjustments, and exchange variation, when applicable, as well as variations arising from adjustment to fair value are recognized in the income statement when incurred.

Available for sale securities are stated at fair value. Interest, monetary adjustments, and exchange variation, when applicable, are recognized in income when incurred. The variations arising from adjustment to fair value, except for impairment losses, are recognized in other comprehensive income when incurred. Gains and losses recorded in Equity are recognized in the income statement for the year when these investments are sold or considered not recoverable.

c) Trade Accounts Receivable - Net

Trade accounts receivable are stated at amortized cost, less impairment losses, when applicable, and accounts receivable from foreign customers are adjusted based on exchange rates in effect at the date of the Consolidated Financial Statements. The allowance for doubtful accounts is calculated based on a risk assessment, which considers historical losses, individual situation of each customer and the situation of the economic group to which they belong, applicable collateral and guarantees and legal counsel’s opinion. The allowance is considered sufficient to cover any losses incurred on uncollectible receivables. Information on the breakdown of current and past-due trade accounts receivable and the related allowance for doubtful accounts is provided at note 5.

d) Impairment of Financial Assets

Financial assets are assessed at each balance sheet date for evidence of impairment. They are considered impaired when there is evidence that one or more events have occurred after the initial recognition of the financial asset and such event or events had a negative impact on the estimated future cash flows of the investment.

2.4 — Inventories

Inventories are measured based on the lower of historical cost of acquisition and production and net realizable value. The acquisition and production costs are increased by transport, storage and non-recoverable taxes expenses.

Net realizable value is the estimated sale price in the ordinary course of business less the estimated costs of completion and selling expenses directly related. Information regarding the allowance for adjustments to net realizable value is demonstrated at note 6.

2.5 - Property, Plant and Equipment

Property, plant and equipment are stated at historical cost, monetarily adjusted when applicable in accordance with IAS 29, less depreciation, except for land, which is not depreciated, and less impairment losses, when applicable. The Company recognizes monthly as part of the acquisition cost of the property, plant and equipment in process the borrowing costs incurred on loans and financing considering the following capitalization criteria: (a) the capitalization period occurs when the property, plant and equipment item is on construction in process and the capitalization of borrowing costs are ceased when the asset is available for use; (b) borrowing costs are capitalized considering the weighted average rate of loans existing on the capitalization date or a specific rate, in the case of loans to acquire property, plant and equipment; (c) borrowing costs capitalized monthly do not exceed the interest expenses calculated in the period of capitalization; and (d) capitalized borrowing costs are depreciated considering the same criteria and useful life determined for the property, plant and equipment item to which it was capitalized. Forestation/reforestation assets are measured at fair value on the date of financial statements, when fair value can be measured reliably, or at cost in accordance with IAS 41.

Depreciation is calculated under the modified straight-line method at rates that take into consideration the estimated useful lives of the assets, its level of utilization and the estimated residual value of the asset at the end of its useful life.

Subsequent costs are added to the residual value of property, plant and equipment or recognized as a specific item, as appropriate, only if the economic benefits associated to these items are probable and the amounts can be reliably measured. The residual value of the replaced item is written off. Other repairs and maintenance are recognized directly in income when incurred.

The estimated residual value of the asset at the end of its useful life and useful life of the assets are reviewed and adjusted, if necessary, at the fiscal year-end.

The net book value of property, plant and equipment is written off immediately when it exceeds its recoverable amount by the amount the net book value exceeds the recoverable amount (note 2.7).

2.6 — Other Intangible Assets

Other intangible assets are stated at acquisition cost, less accumulated amortization and impairment losses, when applicable. Intangible assets consist of carbon emission reduction certificates, and customer contracts and relationships, which represent the capacity to add value of acquired companies based on the relationship with customers. Intangible assets with definite useful lives are amortized taking into consideration their effective use or a method that reflects their economic benefit. The net book value of intangible assets is written off immediately when it exceeds the estimated recoverable amount by the amount the net book value exceeds the recoverable amount (note 2.7).

Intangible assets acquired in a business combination are recorded at fair value, less accumulated amortization and impairment losses, when applicable. Intangible assets that do not have indefinite lives are amortized over their useful lives using an amortization method which reflects the economic benefit of the intangible asset. The customer and supplier relationship intangible asset is amortized based on an accelerated method that considers the expected future economic benefit provided by those acquired customers and suppliers over time. Intangible assets are reviewed for impairment annually or if events or changes in circumstances indicate that the carrying amount may not be recoverable.

The Company reviews the amortization period and amortization method for intangible assets with definite useful lives at the end of each year.

2.7 — Provision for Impairment of Long-Lived Assets and Reversal of Impairment

On the date of each Consolidated Financial Statement, the Company performs an analysis to determine if there is evidence that the carrying amount of long-lived assets is impaired. If such evidence is identified, the recoverable amount of the assets is estimated by the Company.

GERDAU S.A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2011, 2010 and 2009

(in thousands of Brazilian reais — R$, unless otherwise stated)

The recoverable amount of an asset is determined as the higher of: (a) its fair value less estimated costs to sell and (b) its value in use. The value in use is measured based on discounted cash flows (before taxes) derived from the continuous use of the asset until the end of its estimated useful life.

Regardless of whether or not there is any indication that the carrying amount of the asset may not be recovered, the balances of goodwill arising from business combinations and intangible assets with indefinite useful lives are tested for impairment at least once a year in December.

When the carrying amount of the asset exceeds its recoverable amount, the Company reduces the asset’s carrying amount to the recoverable amount.

The reduction to the recoverable amount of assets is recorded in income for the year.

Except for an impairment of goodwill, a reversal of previously recorded impairment losses is allowed. Reversal in these circumstances is limited up to the amount of depreciated balance of the asset at the date of the reversal, determined as if the impairment had not been recorded, as demonstrated at note 27.2.

2.8 — Investments

a) Investments in Subsidiaries

The Company’s consolidated financial statements include the financial statements of Gerdau S.A. and all its subsidiaries. The Company considers that it has control when it directly or indirectly holds a majority of the voting rights in the Shareholders Meetings or has the power to determine the financial and operational policies in order to obtain benefits from its activities. In situations in which the Company in essence holds control of other special purpose entities, even though it does not control a majority of the voting rights, these entities are consolidated under the full consolidation method.

Third parties’ interests in equity and net income of subsidiaries are reported separately in the consolidated balance sheet and in the consolidated statement of income, respectively, under the account “Non-controlling interests”.

For companies acquired after January 1, 2006, which is the Company’s transition date to IFRS, the assets, liabilities, and contingent liabilities of a subsidiary are reported at their respective fair value on the date of acquisition. Any excess of the acquisition cost over the fair value of the identifiable net assets acquired is recorded as goodwill. When the acquisition cost is less than the fair value of the net assets identified, the difference is recorded as a gain in the statement of income for the year in which the acquisition took place. The non-controlling interests are presented based on the proportion of the fair value of the assets and liabilities identified.

Net income of the subsidiaries acquired or sold during the year is included in the statement of income from the acquisition date or until the sale date, respectively, when applicable. Intercompany transactions and balances are eliminated in the consolidation process. Gains or losses resulting from the transactions among consolidated entities of the Company are also eliminated.

Adjustments are made to the Financial Statements of the subsidiaries whenever necessary in order for them to be in accordance with the respective accounting practices established by the IFRS and adopted by the Company.

b) Investments in Jointly-Controlled Entities

Jointly-controlled entities are those in which the control is held jointly by the Company and one or more partners. Investments in jointly-controlled entities are recognized under the equity method from the date the joint control is acquired. According to this method, investments in jointly-controlled entities are recognized in the consolidated balance sheet at acquisition cost and are adjusted periodically based on the Company’s share in earnings and other variations in

Equity of these companies. Additionally, the balances of the investments can be reduced due to impairment losses.

Losses in jointly-controlled entities in excess of the investment in these entities are not recognized, except when the Company is contractually obligated or has agreed to reimburse these losses.

Any excess of the acquisition cost of an investment over the net fair value of assets, liabilities and contingent liabilities of a jointly-controlled entity on the respective acquisition date of the investment is recorded as goodwill. Goodwill is added to the value of the respective investment and its recovery is analyzed annually as an integral part of the investment. When the acquisition cost is less than the fair value of the net assets identified, the difference is recorded as a gain in the statement of income for the year in which the acquisition takes place.

Furthermore, dividends received from these companies are recorded as a reduction in the value of the investments.

Gains and losses on transactions with jointly-controlled entities are eliminated against the value of the investment in these jointly-controlled entities proportionately to the Company’s interest.

c) Investments in Associate Companies

An associate company is one over which the Company exercises significant influence by participating in the decisions related to its financial and operational policies, but over which it does not have control or joint control of its policies.

Investments in associate companies are recorded under the equity method. According to this method, investments in associate companies are recognized in the consolidated balance sheet at cost and are adjusted periodically for the share in their earnings against gains and losses on financial assets and other variations in net assets acquired. Additionally, investments can be adjusted to recognize impairment losses.

Losses on associate companies in excess of the investment in these entities are not recognized, except when the Company has agreed to cover these losses.

Any excess of the acquisition cost of an investment over the net fair value of the assets, liabilities, and contingent liabilities of the associate company on the respective acquisition date of the investment is recorded as goodwill. The goodwill is added to the value of the respective investment and its recovery is analyzed annually as an integral part of the investment. When the acquisition cost is less than the fair value of the net assets identified, the difference is recorded as a gain in the statement of income for the year in which the acquisition takes place.

Furthermore, dividends received from these companies are recorded as a decrease in the value of the investments.

Gains and losses on transactions with associate companies are eliminated proportionately to the Company’s interest against the value of the investment in these associate companies.

2.9 — Financial Liabilities and Equity Instruments

a) Classification as Debt or Equity

Debt or equity instruments are classified in accordance with the substance of the contractual terms.

b) Short and Long-Term Debts

Short and Long-Term Debts are stated at amortized cost.

They are stated net of transaction costs, and are subsequently measured at the amortized cost using the effective interest method.

(in thousands of Brazilian reais — R$, unless otherwise stated)

c) Equity Instruments

An equity instrument is based on a contract that evidences a residual interest in the assets of an entity after deducting its liabilities.

d) Derivative Instruments and hedge

The Company enters into derivative financial instruments mainly to manage its exposure to fluctuation in interest rates and exchange rates. The Company measures its derivative financial instruments based on quoted prices for similar assets, which are the fair value of the financial instruments on the date of the Consolidated Financial Statement.

Changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash flow hedge or a net investment hedge are recorded in the statement of comprehensive income.

The Company assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. When a hedging instrument is sold, terminated, expires or exercised, the cumulative unrealized gain or loss, which had been recognized in the statement of comprehensive income, is reclassified immediately in the statement of income. Additionally, changes in the fair value of financial instruments not characterized as hedge are recognized in the financial expense or financial income accounts in the Income Statement.

Foreign currency differences arising on the retranslation of a financial liability designated as a hedge of a net investment in a foreign operation are recognized in the statement of comprehensive income, to the extent that the hedge is effective. To the extent that the hedge is ineffective, such differences are recognized in the statement of income.

The potential cash payments related to put options issued by the Company over the equity of subsidiaries are accounted under account “Put options on non-controlling interest”. The amount that may become payable under the option on exercise is initially recognized at fair value and are subsequently measured in order to accrete the liability up to the date on which it becomes exercisable. The charge arising is recorded as a financial expense in the statement of income. In the event that the option expires unexercised, the liability is derecognized with a corresponding adjustment to equity.

2.10 — Current and Deferred Income and Social Contribution Taxes

Current income and social contribution tax expense is calculated in conformity with current tax laws in effect at the date of the financial statements in the countries where the Company’s subsidiaries, associates and jointly-controlled entities operate and generate taxable income. Management periodically evaluates positions taken in relation to tax matters which are subject to interpretation and recognizes a provision when there is an expectation of payment of income tax and social contribution as tax bases.

Current tax is the tax payable or receivable on the expected taxable income or loss for the year, at the tax rates effective at the date of the financial statements.

Deferred income and social contribution taxes are recognized for differences between assets and liabilities recognized for tax purposes and related amounts recognized in the Consolidated Financial Statements. However, deferred income and social contribution taxes are not recognized if they arise at the initial recognition of assets and liabilities from operations that do not affect the tax bases, except in business combinations. Deferred income and social contribution taxes are determined based on the tax rates and laws in effect at the date of the Consolidated Financial Statements and applicable when the respective income and social contribution taxes be realized.

Deferred income and social contribution tax assets are recognized only to the extent that it is probable that there will be taxable income for which temporary differences and tax losses can be utilized.

GERDAU S.A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2011, 2010 and 2009

(in thousands of Brazilian reais — R$, unless otherwise stated)

Deferred income tax and social contribution assets are reviewed at each closing date and will be reduced to the extent that their realization is not more likely than not.

The expense for income tax and social contribution taxes comprises current and deferred taxes. Current tax and deferred tax is recognized in income unless they are related to business combination, or items directly recognized in equity or in other comprehensive income.

Deferred tax is recognized related to temporary differences between the carrying amounts of assets and liabilities for accounting purposes and the corresponding amounts used for taxation purposes. Deferred tax is not recognized for the following temporary differences: the initial recognition of assets and liabilities in a transaction other than a business combination and that do not affect neither accounting books nor taxable profit or loss, and differences associated with investments in subsidiaries and controlled entities when it is probable that they do not reverse in the foreseeable future. In addition, deferred tax is not recognized for taxable temporary differences arising on initial recognition of goodwill. Deferred tax is measured at the tax rates expected to apply to temporary differences when they reverse, based on the laws that were enacted or substantively enacted as of the date of submission of the financial statements.

An income and social contribution tax asset is recognized for tax losses, tax credits and deductible temporary differences not used when it is probable that future profits subject to taxation will be available against which will be used.

The Company only recognizes a provision on tax issues if a past event leads to a present obligation. The Company determines whether a present obligation exists at the year end and taking into consideration all available evidence, including, for example, the opinion of legal advisors. The Company also considers whether it is probable that there will be an outflow of assets and a reliable estimate can be made of the amount of the obligation.

2.11 — Employee Benefits

The Company has several employee benefit plans including pension and retirement plans, health care benefits, profit sharing, bonus, and share-based payment, as well as other retirement and termination benefits. The main benefit plans granted to the Company’s employees are described at notes 19 and 24.

The actuarial obligations related to the pension and retirement benefits and the actuarial obligations related to the health care plans are recorded based on actuarial calculations performed every year by independent actuaries, using the projected unit credit method, net of the assets that fund the plan, when applicable, and the related costs are recognized over the employees’ vesting period. Any employee benefit plan surpluses are also recognized up to the probable amount of reduction in future contributions of the plans’ sponsor.

The projected unit credit method considers each period of service as a triggering event of an additional benefit unit, which is accrued to calculate the total obligation. Other actuarial assumptions are also used such as estimates of the increase of healthcare costs, demographical and economic hypotheses and, also, historical costs and employee contributions.

Actuarial gains and losses arising from adjustments and changes in actuarial assumptions of the pension and retirement benefit plans and actuarial obligations related to the health care plan are recognized directly in the Statement of Comprehensive Income as described at Note 19. The Company believes that the recognition of actuarial gains and losses in comprehensive income provides a better presentation of these changes in the consolidated financial statements when considered as a whole.

2.12 - Other Current and Non-current Assets and Liabilities

They are recorded at their realizable amounts (assets) and at their known or estimated amounts plus accrued charges and monetary adjustments (liabilities), when applicable.

2.13 — Related-Party Transactions

Loan agreements between the entities in Brazil and abroad within the Company are adjusted by contracted charges plus foreign exchange variation, when applicable. Sales and purchases of inputs and products are made under terms and conditions as stated in contracts between the parties.

2.14 — Dividend Payment

Dividend payments are recognized as liabilities at the time dividends are approved by the shareholders of Gerdau S.A. The bylaws of Gerdau S.A. specify dividends of not less than 30% of the annual income; therefore, Gerdau S.A. records a provision at year-end for the minimum dividend amount that has not yet been paid during the year up to the limit of the mandatory minimum dividend described above.

2.15 — Revenue Recognition

Sales revenues are presented net of taxes and discounts. Taxes on sales are recognized when sales are invoiced and discounts on sales are estimated and recognized when known. Revenues from sales of products are recognized when the sales amount is reliably measured, the Company no longer has control over the goods sold or any other responsibility related to its ownership, the costs incurred or that will be incurred related to the transaction can be reliably measured, it is more likely than not that the economic benefits will be received by the Company, and the risks and benefits of the products have been fully transferred to the buyer. The related costs of freight are included in cost of sales.

2.16 - Investments in Environmental Protection

Environmental costs that relate to current operations are expensed or capitalized as appropriate. Environmental costs that relate to an existing condition caused by past operations, and which do not contribute to current or future revenue generation or cost reduction are expensed. Liabilities are recorded when environmental assessments and or remedial efforts are probable and the cost can be reasonably estimated based on discussions with the environmental authorities and other assumptions relevant to the nature and extent of the remediation that may be required. The ultimate cost to the Company is dependent upon factors beyond its control such as the scope and methodology of the remedial action requirements to be established by environmental and public health authorities, new laws or government regulations, rapidly changing technology and the outcome of any potential related litigation. Environmental liabilities are adjusted to present value using a rate of 7% per year.

2.17 — Lease Contracts

Leases are classified as finance leases whenever the terms of lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases. Payments made on operational lease contracts are charged to income on a straight-line basis over the period of the lease.

2.18 - Use of Estimates

The preparation of the Consolidated Financial Statements requires estimates to record certain assets, liabilities and other transactions. To make these estimates, Management used the best information available on the date of preparation of the Consolidated Financial Statements and the experience of past and/or current events, also considering assumptions related to future events. The Consolidated Financial Statements include, therefore, estimates for the determination of useful lives of property, plant and equipment (note 9), estimates of the recoverable amount of long-lived assets (note 27), with respect to the need and the amount of provisions for tax, civil and labor liabilities (note 17), for the determination of income taxes (note 8), in determining the fair value of financial instruments (assets and liabilities) and other instruments (note 15), estimates in selecting interest rates, expected return on assets, mortality tables and expectations for salary increases in long-term postretirement benefits (note 19), and estimates when selecting the valuation model and inputs used in measuring share-based compensation (note 24). Actual results could differ from those estimates.

2.19 - Business Combinations

a) Step-acquisitions in which control is obtained

When a business combination is achieved in stages, the interest previously held by the Company in the acquired entity is remeasured at fair value at acquisition date (i.e. the date when the Company acquires the control) and the resulting gain or loss, if any, is recognized in profit or loss. The amounts of interests on the acquired company before the acquisition date that was recognized in “Other comprehensive income” are reclassified to profit or loss, where such treatment would be appropriate if that interest were disposed of.

b) Acquisitions in which control is obtained initially

Acquisitions of businesses are accounted under the acquisition method. The cost of the acquisition is measured at the aggregate of the fair values (at the date of exchange) of assets given and liabilities incurred or assumed and equity instruments issued by the Group in exchange for the control of the acquired business entity. The acquiree’s identifiable assets, liabilities and contingent liabilities are recognized at their fair values at the acquisition date. The interest of non-controlling shareholders in the acquiree is initially measured at the non-controlling shareholder’s proportion of the net fair value of the assets, liabilities and contingent liabilities recognized. Expenses related to the acquisition are recognized in the income statement when incurred.

Contingent consideration is measured at fair value at the acquisition date; subsequent adjustments to the consideration are recognized against goodwill only to the extent that they arise from better information about the fair value at the acquisition date, and they occur within the ‘provisional period’ (a maximum of 12 months from the acquisition date). All other subsequent adjustments are recognized in profit or loss.

c) Increases/decreases in non-controlling interests

In prior years, in the absence of specific requirements in IFRS, increases in interests in existing subsidiaries were treated in the same manner as the acquisition of subsidiaries, with goodwill or a bargain purchase gain being recognized where appropriate.

Currently, the impact of increases and decreases in interests in subsidiaries that do not involve loss of control are accounted for within equity, with no impact on goodwill or profit or loss.

Subsequent purchases, after the Company has obtained control, are treated as the acquisitions of shares from non-controlling shareholders: the identifiable assets and liabilities of the entity are not subject to a further revaluation and the positive or negative difference between the cost of such subsequent acquisitions and the net value of the additional proportion of the company is accounted for within equity.

d) Loss of control of a subsidiary

When control of a subsidiary is lost as a result of a transaction, event or other circumstance, the Company derecognizes all assets, liabilities and non-controlling interests at their carrying amount. Any retained interest in the former subsidiary is recognized at its fair value at the date that control is lost. This fair value is reflected in the calculation of the gain or loss on disposal attributable to the parent, and becomes the initial carrying amount for subsequent accounting for the retained interest under IAS 28, IAS 31 or IAS 39.

2.20 — Restructuring Provision

A restructuring provision is recognized when the Company has a detailed restructuring plan approved and the restructuring was already initialized or been publically announced. Future operational losses provisions are not recognized.

2.21 - Application of Judgment and Critical Accounting Policies when Preparing Consolidated Financial Statements

Critical accounting policies are those that are both (a) important to present the financial position and results of operations and (b) require Management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates that impact matters that are inherently uncertain. As the number of variables and assumptions affecting the possible future resolution of the uncertainties increases, those judgments become even more subjective and complex. In the preparation of the Consolidated Financial Statements, the Company has relied on variables and assumptions derived from historical experience and various other factors that it deems reasonable and relevant. Although these estimates and assumptions are reviewed by the Company in the normal course of business, the presentation of its financial position and results of operations often requires making judgments regarding the effects of inherently uncertain matters on the carrying value of its assets and liabilities. Actual results may differ from estimates based on different variables, assumptions or conditions. In order to provide an understanding of how the Company forms its judgments about future events, including the variables and assumptions underlying the estimates, comments have been included that relate to each critical accounting policy described below:

a) Deferred Income and Social Contribution Tax

The liability method of accounting (according to the concept described in IAS 12) for income taxes is used for deferred income and social contribution taxes arising from temporary differences between the book value of assets and liabilities and their tax bases. The amount of the deferred income and social contribution tax asset is revised at each Consolidated Financial Statement date and reduced by the amount that is no longer probable of being realized based on future taxable income. Deferred income and social contribution tax assets and liabilities are calculated using tax rates applicable to taxable income in the years in which those temporary differences are expected to be realized. Future taxable income may be higher or lower than estimates made when determining whether it is necessary to record a tax asset and the amount to be recorded.

The realization of deferred tax assets for tax loss carryforwards are supported by projections of taxable income based on technical feasibility studies submitted annually to the Company’s Board of Directors. These studies consider historical profitability of the Company and its subsidiaries and expectation of continuous profitability and estimated the recovery of deferred tax assets over future years. The other tax credits arising from temporary differences, mainly tax contingencies, and provision for losses, were recognized according to their estimate of realization.

b) Pension and Post-Employment Benefits

Actuarial gains and losses are recorded in the period in which they are originated and are recorded in the statement of comprehensive income.

The Company recognizes its obligations related to employee benefit plans and related costs, net of plan assets, in accordance with the following practices:

i) The cost of pension and other post-employment benefits provided to employees is actuarially determined using the projected unit credit method and management’s best estimate of expected investment performance for funded plans, salary increase, retirement age of employees and expected health care costs. The discount rate used for determining future benefit obligations is an estimate of the interest rate in effect at the balance sheet date on high-quality fixed-income investments with maturities that match the expected maturity of obligations.

ii) Pension plan assets are stated at market value.

iii) Gain and losses related to the curtailment and settlement of the defined benefit plans are recognized when the curtailment or settlement occurs and they are based in actuarial evaluation done by independent actuaries.

In accounting for pension and post-retirement benefits, several statistical and other factors that attempt to anticipate future events are used to calculate plan expenses and liabilities. These factors include discount rate assumptions,

F-19

GERDAU S.A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2011, 2010 and 2009

(in thousands of Brazilian reais — R$, unless otherwise stated)

expected return on plan assets, future increases in health care costs, and rate of future compensation increases. In addition, actuarial computation other factors whose measurement involves judgment are used such as withdrawal, turnover, and mortality rates. The actuarial assumptions used by the Company may differ materially from actual results in future periods due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates, or longer or shorter participant life spans.

c) Environmental Liabilities

The Company records provisions for environmental liabilities based on best estimates of potential clean-up and remediation costs for known environmental sites. The Company has a team of professionals to manage all phases of its environmental programs. These professionals develop estimates of liabilities at these sites based on projected and known remediation costs. This analysis requires the Company to make significant estimates and changes in facts and circumstances may result in material changes in environmental provisions.

The steel industry uses and generates substances that may damage the environment. The Company’s management performs frequent surveys with the purpose of identifying potentially impacted areas and records as current and noncurrent liabilities in the account ‘Environmental liabilities’, based on best cost estimate, the amounts estimated for investigation, treatment and cleaning of potentially affected sites. The Company used assumptions and estimates for determining the estimated amount, which may vary in the future depending on the final investigations and determination of the actual environmental impact.

The Company is compliant with all the applicable environmental regulations in the countries where it operates (note 20).

d) Derivative Financial Instruments

The Company measures its derivative financial instruments based on quoted prices for similar assets, which are the fair value of the financial instruments on the date of the Consolidated Financial Statements. Intense volatility in the foreign exchange and interest rate markets in Brazil has caused, in certain periods, significant changes in forward rates and interest rates over very short periods of time, generating significant changes in the fair value of swaps and other financial instruments over a short period of time. The fair value recognized in its Consolidated Financial Statements may not necessarily represent the amount of cash that the Company would receive or pay, as applicable, if the Company would settle the transactions on the Consolidated Financial Statements date.

e) Useful Lives of Long-Lived Assets

The Company recognizes depreciation of its long-lived assets based on estimated useful lives, which are based on industry practices and prior experience and reflect economic lives of long-lived assets. However, actual useful lives can vary based on technological update of each unit. Useful lives of long-lived assets also affect impairment tests of those long-lived assets, when required.

The Company does not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions used to calculate long-lived asset impairment losses. However, if actual results are not consistent with estimates and assumptions used in estimating future cash flows and asset fair values, the Company may be exposed to losses that could be material.

f) Fair Value of Unquoted Derivative Financial Instruments

The Company has entered into financial instruments in connection with some of its acquisitions, which involve commitments to acquire shares from non-controlling interests of the acquired companies, or grant of put options to some non-controlling interests to sell to the Company their shares. Such derivatives are recorded on the Company’s balance sheet in the account ‘Put options on non-controlling interest’ (note 15.f), and the determination of this value involves a series of estimates that can materially impact its final

result. The Company estimates the fair value of the companies

(in thousands of Brazilian reais — R$, unless otherwise stated)

whose shares the Company is committed to acquire using criteria established in each contract, which are in line with practices observed in the market for estimating fair value of unquoted instruments.

g) Valuation of Assets Acquired and Liabilities Assumed in Business Combinations

During the last several years, as described at note 3, the Company has made certain business combinations. According to IFRS 3(R), effective for business combinations that have occurred after the IFRS transition date, the Company should allocate the cost of the acquired entity to the assets acquired and liabilities assumed based on their fair value estimated on the date of acquisition. Any difference between the cost of the acquired entity and the fair value of the assets acquired, liabilities assumed is recorded as goodwill. The Company exercises significant judgment in the process of identifying tangible and intangible assets and liabilities, valuing these assets and liabilities, and estimating their remaining useful life. The valuation of these assets and liabilities is based on assumptions and criteria that, in some cases, include estimates of future cash flow discounted at the appropriate rates. The use of valuation assumptions includes discounted cash flows estimates or discount rates and may result in estimated values that are different from the assets acquired and liabilities assumed.

The Company does not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions used to complete the purchase price allocation and estimate the fair value of acquired assets and liabilities. However, if actual results are not consistent with estimates and assumptions considered, the Company may be exposed to losses that could be material.

h) Impairment Test of Assets with definite and indefinite useful life

There are specific rules to assess the impairment of long-lived assets, especially property, plant and equipment, goodwill and other intangible assets. On the date of each Financial Statement, the Company performs an analysis to determine if there is evidence that the carrying amount of long-lived assets is impaired. If such evidence is identified, the recoverable amount of the assets is estimated by the Company.

The recoverable amount of an asset is determined as the higher of: (a) its fair value less estimated costs of sale and (b) its value in use. The value in use is measured based on discounted cash flows (before taxes) derived from the continuous use of the asset until the end of its useful life.

Regardless of whether or not there is any indication that the carrying amount of the asset may not be recovered, the balances of goodwill arising from business combination and assets with indefinite useful life are tested for impairment at least once a year, in December.

When the residual carrying value of the asset exceeds its recoverable amount, the Company recognizes a reduction in this asset’s book balance.

For assets recorded at cost, the reduction in recoverable amount must be recorded in income for the year. If the recoverable amount of an asset is not determined individually, the recoverable amount of the business segment to which the asset belongs is analyzed.

Except for the impairment of goodwill, a reversal of previously recorded impairment losses is allowed. Reversal in these circumstances is limited up to the amount of depreciated balance of the asset at the date of the reversal, determined considering as if the impairment had not been recorded.

The Company evaluates the recoverability of goodwill on investments annually and uses accepted market practices, including discounted cash flow for units with goodwill allocated and comparing the book value with the recoverable amount of the assets.

Recoverability of goodwill is evaluated based on the analysis and identification of facts and circumstances that can indicate the necessity to anticipate the test that is performed annually. If some fact or circumstance indicates that the recoverability of goodwill is affected on an interim period, then the test is anticipated. In December 2011, the Company carried out goodwill impairment tests for all of its operating segments, which represent the lowest level at which goodwill is monitored by management based on projections for expected discounted cash flows and that take into consideration the following assumptions: cost of capital, growth rate and adjustments used for perpetual cash flows, methodology for determining working capital, investment plans, and long-term economic-financial forecasts.

The tests carried out did not identify any new impairment to the Company’s goodwill as well as other assets with indefinite useful life.

Goodwill that forms part of the carrying amount of an investment in an associate or in a jointly-controlled entity is not separately recognized and it is not tested for impairment separately. Instead, the entire carrying amount of the investment in an associate or in a jointly-controlled entity is tested for impairment as a single asset, by comparing its recoverable amount (higher of value in use and fair value less costs to sell) with its carrying amount. An impairment loss recognized in those circumstances is not allocated to any asset, including goodwill that forms part of the carrying amount of the investment in the associate or jointly-controlled entity. Accordingly, any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases.

The recoverability review process is subjective and requires significant judgments through analysis performed. The determination of the value in use of the Company’s operating segments, based on projected cash flows may be negatively impacted if the economy global recovery happens slowly than expected during the preparation of financial statements in December 2011.

2.22 - New IFRS and Interpretations of the IFRIC (International Financial Reporting Interpretations Committee)

3.4 - Goodwill

Goodwill represents the excess of the acquisition cost over the net fair value of the assets acquired, liabilities assumed, and identifiable contingent liabilities of the Company’s subsidiaries, jointly-controlled entities, or associate company at the respective date of acquisition.

Goodwill related to investments in foreign companies is reported in the functional currency of the party acquiring these subsidiaries and translated to Brazilian reais (the Company’s reporting currency) at the exchange rate in effect at the balance sheet date. The exchange rate differences arising from this translation are recorded under the account “Cumulative translation difference” in Equity after the date of transition to IFRS.

Goodwill is recorded as an asset under the accounts “Investments in associates and jointly-controlled entities” and “Goodwill”. Goodwill is not amortized and it is subject to impairment tests annually or whenever there are indications of impairment. Any impairment loss is immediately recorded as a cost in the statement of income and shall not be reversed later. Goodwill related to the Company’s subsidiaries is allocated to the operating segments, which represent the lowest level at which goodwill is monitored by management.

At the time of selling a subsidiary, jointly-controlled entity or associate company, goodwill is included in the determination of the gain or loss.

3.5 - Acquisition of additional interest in subsidiaries and business combinations

Sipar Gerdau Inversiones S.A.

On April 1, 2011, the Company acquired an additional interest of 7.25% in the subsidiary Sipar Gerdau Inversiones S.A.. The total amount of this acquisition, to be paid by February 2015, was US$ 7,590 thousand (R$ 11,941 in the acquisition date) and as a result of this operation, in accordance with the standard IAS 27, the Company recognized in Equity, the amount of R$ 8,085, which is the difference between the purchase price paid and the amount of the non-controlling interest in the net assets acquired.

The Company’s maximum exposure to credit risk, net of the allowance for doubtful accounts, is the amount of the accounts receivable listed above. The actual risk of losses is presented as allowance for doubtful accounts.

The credit risk results from the possibility of the Company not receiving amounts arising from sales operations. In order to minimize this risk, the Company adopts the procedure of carefully analyzing the financial position of its customers, establishing a credit limit, and constantly monitoring customers’ balances. The allowance is calculated based on a credit risk assessment, which considers historical losses, individual situation of each customer and the economic group to which they belong, applicable collateral and guarantees and legal counsel’s opinion, and is considered sufficient to cover any losses on uncollectible receivables.

The aging list of trade accounts receivable is as follows:

The units of the subsidiary Gerdau Aços Longos S.A., located in the northeast region of Brazil, will receive until 2013, a 75% reduction in income tax on operating profit, which represented R$ 0 as of December 31, 2011 (R$ 23,831 and R$ 52,149 during the years ended December 31, 2010 and 2009, respectively). The respective tax incentives were recorded directly in the income and social contribution tax accounts in the statement of income.

On December 31, 2011, the Company has a total of tax losses carryforwards arising from its operations in Brazil of R$ 606,139 Income tax (R$ 607,370 and R$ 340,248 during the years ended December 31, 2010 and 2009, respectively) and a total of negative basis of social contribution R$ 1,291,616 (R$ 849,446 and R$ 418,285 during the years ended December 31, 2010 and 2009, respectively), representing a deferred tax asset of R$ 267,780 (R$ 228,293 and R$ 122,708 during the years ended December 31, 2010 and 2009, respectively).

Goodwill impairment test

The Company evaluates the recoverability of goodwill on investments annually and uses accepted market practices, as the discounted cash flow for operating segments which have goodwill.

Recoverability of goodwill is evaluated based on analysis and identification of facts and circumstances that could result in the need of anticipation for the tests performed annually. If some fact or circumstance indicates that the recoverability of goodwill is affected, then the test is performed in advance. In the year ended December 31, 2011, the Company carried out goodwill impairment tests for all of its operating segments, which represented the lowest level at which goodwill is monitored by management, based on projections for expected discounted cash flows and which took into consideration the following assumptions: cost of capital, growth rate and adjustments used for perpetual cash flows, methodology for determining working capital, investment plans, and long-term economic-financial forecasts.

The results of recoverability of goodwill are disclosed at Note 27.

c) Risk factors that could affect the Company’s and its subsidiaries’ business:

Price risk of commodities: this risk is related to the possibility of changes in prices of the products sold by the Company or in prices of raw materials and other inputs used in the productive process. Since the Company operate in a commodity market, its sales revenues and cost of sales may be affected by changes in the international prices of their products or materials. In order to minimize this risk, the Company constantly monitors the price variations in the domestic and international markets.

Interest rate risk: this risk arises from the possibility of losses (or gains) due to fluctuations in interest rates applied to the Company’s assets (investments) or liabilities in the market. In order to minimize possible impacts from interest rate fluctuations, the Company adopts a diversification policy, alternating from variable (such as LIBOR and CDI) to fixed rates when contracting debts and hedges and periodically renegotiating contracts to adjust them to market.

Exchange rate risk: this risk is related to the possibility of fluctuations in exchange rates affecting financial expenses (or income) and the liability (or asset) balance of contracts denominated in foreign currency. The Company assesses its exposure to the exchange rate by subtracting its liabilities from its assets in dollars or other foreign currencies, having in this way the net exchange rate exposure basis, which is the basis subject to effects in a change in the foreign currency. Therefore, along with accounts receivable originated from exports and investments abroad that in economic terms result in a natural hedge, the Company assesses using hedge operation, more commonly swap operations, if the Company has more liabilities in dollars than assets.

Credit risk: this risk arises from the possibility of the Company not receiving amounts arising from sales to customers or investments made with financial institutions. In order to minimize this risk, the Company adopts the procedure of analyzing in detail the financial position of their customers, establishing a credit limit and constantly monitoring their balances. In relation to cash investments, the Company invests solely in financial institutions with low credit risk, as

(in thousands of Brazilian reais — R$, unless otherwise stated)

assessed by rating agencies. In addition, each financial institution has a maximum limit for investment, determined by the Company’s Credit Committee.

Capital management risk: this risk comes from the Company’s choice in adopting a financing structure for its operations. The Company manages its capital structure, which consists of a ratio between the financial debts and its own capital (Equity, retained earnings, and profit reserves) based on internal policies and benchmarks. The BSC (Balance Scorecard) methodology has been used in the last years to elaborate strategic maps with objectives and indicators of the main processes. The KPIs (Key Performance Indicators) related to the objective “Capital Structure Management” are: WACC (Weighted Average Cost of Capital), Total Indebtedness/adjusted EBITDA, Interest Coverage Ratio, and Indebtedness/Equity Ratio. The Total Debt is composed of loans and financing (note 13) and debentures (note 14). The Company can change its capital structure depending on economic-financial conditions in order to optimize its financial leverage and its debt management. At the same time, the Company tries to improve its ROCE (Return on Capital Employed) by implementing a working capital management process and an efficient fixed asset investment program.

The Company seeks to remain between the following parameters:

WACC |  | between 10% to 13% a year
Gross debt/EBITDA |  | between 2 and 3 times
Interest Coverage Ratio |  | greater than 5 times
Debt/Equity Ratio |  | between 40%-60% and 60%-40%

These key indicators are used for the objectives described above and may not be used as indicators for other purposes, such as impairment tests.

Liquidity risk: the Company’s management policy of indebtedness and cash on hand is based on using the committed lines and the currently available credit lines with or without a guarantee in export receivables for maintaining adequate levels of short, medium, and long-term liquidity. The maturity of long-term loans, financing, and debentures are presented at Notes 13 and 14, respectively.

Sensitivity analysis

The Company performed the following sensitivity analysis:

Impacts on Statements of Income |  |  |  |  |
Assumptions |  | Variance |  | 2011 |
Foreign currency sensitivity analysis |  | 5 | % | 51,594 |
Interest rate sensitivity analysis |  | 0.1 | % | 74,285 |
Price products sensitivity analysis |  | 1 | % | 354,068 |
Sensitivity analysis of changes in sales price of products and price of raw materials |  | 1 | % | 219,458 |
Sensitivity analysis of interest rate swaps |  | 0.1 | % | 1,382 |
Sensitivity analysis of NDF’s (Non Deliverable Forwards) |  | 5 | % | 6,505 |

Foreign currency sensitivity analysis: the Company is exposed to variations in foreign currency, especially in loans and financing in the amount of US$ 550.1 million. The sensitivity analysis made by the Company considers the effects of an increase or a reduction of 5% between the Brazilian real and the foreign currencies on such outstanding loans and financing on the date of the Consolidated Financial Statements. As of December 31, 2011, the Company is mainly exposed to variations between Brazilian real and US Dollar, since the loans taken by the other than Brazilian subsidiaries of the Company are mainly in the same currency of the functional currency of each subsidiary, and because of this aspect, these loans do not expose the Company to variations in foreign currency. The impact calculated considering such variation in the foreign exchange rate totals R$ R$ 51,594 as of December 31, 2011 (R$ 88,535 as of December 31, 2010) and represents an income if an appreciation of the Brazilian real against the US Dollar occurs or an expense in the case of a depreciation of the Brazilian real against the US Dollar.

The net amounts related to accounts receivable and accounts payable in foreign currency do not present relevant risks related to exchange rates fluctuation.

Interest rate sensitivity analysis: the Company is exposed to interest rate risks in its loans and financing and debentures. The sensitivity analysis made by the Company considers the effects of an increase or reduction of 0.1% on outstanding loans and financing and debentures on the date of the Consolidated Financial Statements. The impact calculated considering this variation in the interest rate totals R$ 74,285 as of December 31, 2011 (R$ 77,516 as of December 31, 2010) and would impact the Financial expenses account in the Consolidated Statements of Income. The specific interest rates that the Company is exposed of, which are related to loans, financing, and debentures are described in Notes 13 and 14, and are mainly comprised of Libor and CDI — Interbank Deposit Certificate rates.

Sensitivity analysis of changes in sales price of products and price of raw materials and other inputs used in production: the Company is exposed to changes in the price of its products. This exposure is associated with the fluctuation of the sales price of the Company’s products and the price of raw materials and other inputs used in the production process, especially because the Company operates in a commodities market. The sensitivity analysis made by the Company considers the effects of an increase or of a reduction of 1% on both prices. The impact measured considering this variation in the price of products sold totals R$ 354,068 as of December 31, 2011 (R$ 313,932 as of December 31, 2010) and raw materials and other inputs totals R$ (219,458) as of December 31, 2011 (R$ (182,126) as of December 31, 2010). The impact on the price of products sold and raw materials would be recorded in the accounts Net Sales and Cost of Sales, respectively, in the Consolidated Statements of Income. The Company does not expect to be more vulnerable to a change in one or more specific product or raw material.

Sensitivity analysis of interest rate swaps: the Company has an interest rate swaps exposure for some of its loans and financing. The sensitivity analysis calculated by the Company considers the effects of either an increase or a decrease of 0.1% in the interest curve (Libor), and its impacts in the swaps mark to market. An increase of 0.1% change in the interest rates represents an income of R$ 1,382 (income of R$ 3,347 as of December 31, 2010) and a decrease of 0.1% change in the interest rates represents an expense of R$ 1,382 (expense of R$ 3,347 as of December 31, 2010). All these swaps were contracted to hedge debt positions from floating to fix (Liability). As of December 31, 2011, these effects would be recognized in statement of income in the amount of R$ 1,382 (R$ 311 in the Consolidated Statements of Income and R$ 3,036 in the Consolidated Statements of Comprehensive Income as of December 31, 2010).

e) Operations with derivative financial instruments

Risk management objectives and strategies: The Company believes that risk management is important to carry out its strategy for profitable growth. The Company is exposed to market risks that mainly involve fluctuations in exchange rates and interest rate volatility. The objective of risk management is to eliminate possible unexpected variations in the performance of group’s companies as a result of this fluctuation.

The objective of derivative transactions is always related to mitigation of market risks as stated in our policies and guidelines, as well as to manage volatility in financial flows. The final assessment of results for each contract is measured at the end of each contract when the derivative contract is settled. The monitoring of the effects from these transactions is monthly performed by the Cash Management and Debt Committee, which discusses and validates the marking to market of these transactions. All gains and losses in derivative financial instruments are recognized by its fair value in the Consolidated Financial Statements of the Company.

By internal policy, the Company does not maintain a debt in a currency in which there is no corresponding cash generation.

Policy for use of derivatives: according to internal policy, the financial result must arise from the generation of cash from its business and not gains from the financial market. Therefore, it considers that the use of derivatives should be for non-speculative purposes and intended to hedge the Company from possible exposure to risks. The contracting of a derivative must have as corresponding hedged item an uncovered asset or liability, provided as the position is not leveraged.

Criteria adopted for defining the notional amount of derivative financial instruments are linked to the amount of debt and or assets.

Policy for determining fair value: The criteria to determine the fair value of derivative financial instruments is based on the utilization of market curves for each derivative discounted to present value as of the calculation date. The methods and assumptions take into consideration the interpolation of curves, such as in the case of LIBOR, and according to each market where the company has exposure. The swaps, both on the asset and on the liability side, are estimated in separate and discounted to present value. The difference in the result between extremities generates the swaps market value.

Swap Contracts

Interest rate swap

The subsidiary Gerdau Ameristeel Corp. settled in advance interest rate swap contract qualified as a cash flow hedge with mature between March 2012 and September 2013. These operations were contracted in order to reduce its exposure to the variation in LIBOR for the Term Loan Facility. Since the Term Loan Facility was contracted at floating LIBOR rates, the Company chose to exchange it for fixed rates, thereby improving cash flow predictability, as well as eliminating the floating LIBOR risk. As of December 31, 2011 the effect of these swaps in the statement of income was a loss of R$ 68,698, which was presented in the account “Gains and losses on financial instruments, net” in the consolidated statement of income. The counterparts to this transaction were ABN Amro Bank, HSBC, and JP Morgan.

The Company through its subsidiary GTL Equity Investments Corp. settled swap of Exchange Coupon versus Libor with the bank JP Morgan which matured between December 21, 2010 and December 21, 2011. This operation was entered into in order to take advantage of the difference between the internal interest rate (exchange coupon) and the external interest rate (LIBOR). Because of this, the Company increases its exposure to the Brazil’s risk; however, this risk is related to its business. The fair value adjustment of these contracts as of December 31, 2011 results in a gain of R$ 3,722 which were presented in the account “Gains and losses on financial instruments, net”.

The subsidiary Siderúrgica del Perú S.A.A. - Siderperú entered into a Libor interest rate swap contract whereby it receives a variable interest rate based on LIBOR and pays a fixed interest rate in US dollars. This contract has a notional value of US$ 35.71 million (R$ 66,985 as of December 31, 2011) and maturity date on April 3, 2014. This swap was contracted in order to minimize the risk of interest rate fluctuations (LIBOR) since the Company took on debt in dollars at floating rates for an amount greater than the swap. The fair value adjustment of this contract as of December 31, 2011 results in a net loss of R$ 3,674 presented in the statement of income. The counterparty to this transaction is Banco Bilbao Vizcaya -BBVA.

The subsidiary Gerdau Açominas S.A. entered into an interest rate swap with a notional value of US$ 350 million (R$ 656,530 as of December 31, 2011) and a maturity date of June 22, 2015, on which the financial charges agreed on the debt contract with Banco do Brasil, equivalent to LIBOR plus a percentage of interest, are exchanged for pre-determined interest rates. The fair value adjustment of this contract as of December 31, 2011 results in a net loss of R$ 1,339 presented in the statement of income. The counterparts of this operation are the following banks: HSBC, Citibank and Morgan Stanley.

f) Put options on non-controlling interest

On January 10, 2006, the Company completed its acquisition of 40% of Corporación Sidenor S.A. (“Sidenor”), a Spanish steel producer with operations in Spain and Brazil. The Santander Group, Spanish financial conglomerate, purchased simultaneously 40% of Sidenor. The acquisition price of 100% of Sidenor consists of a fixed installment of € 443,820 plus a contingent variable installment to be paid only by the Company. The fixed price paid by the Company on January 10, 2006 for its interest of 40% in Sidenor was € 165,828 (R$ 432,577). The Santander Group has the option to sell its interest in Sidenor to the Company after 5 years to the purchase at a fixed price with a fixed interest rate, and Sidenor has the right of preference to purchase these shares and also may, at any time during the period of the put option validity require the Santander Group to exercise the put option before the expiration date. On December 23, 2010, the Santander Group and the Company renewed the put option on Sidenor interest and the new maturity date is January 10, 2014, and can be settled in advanced in January at each year after 2012. The option amount is € 208,648 (R$ 464,868), updated according to the fixed interest rate. The potential commitment of the Company to purchase from the Santander Group its 40% interest in Sidenor was recorded as a non-current liability under “Put options on non-controlling interest”. As a result of the recognition of this potential obligation, the Company has recognized since the acquisition date, an additional interest of 40% of Sidenor as its investment. As of December 31, 2011, such potential obligation totaled R$ 528,821 (R$ 464,868 as of December 31, 2010).

The Company had the call option for 16% of the remaining stake in Pacific Coast Steel (PCS) and the non-controlling shareholders also had the option to sell the remaining 16% interest in PCS to the Company. The option was exercised in

(in thousands of Brazilian reais — R$, unless otherwise stated)

2011 for US$ 23 million (R$ 38.8 million) with payment in November 1, 2011, leaving an option for the remaining 1% interest with a fixed price of US$ 3 million, which can be exercised by the Company as from November 1, 2011, while the put option held by minority shareholders shall not be exercised before November 1, 2014. On December 31, 2011, the amount recognized as a potential obligation amounts to R$ 4,723 (US$ 40,341 at December 31, 2010). As a result of this additional interest acquired, the line of non-controlling interests was reduced by the amounts of interest acquired.

The Company had a call option of 7.25% of Sipar Gerdau Inversiones S.A. and the non-controlling shareholders of this entity had the option to sell its 7.25% of its remaining interest to the Company. The option was exercised on April 1, 2011, with payment forecasted to be up to February, 2015, in the amount of US$ 7,590 thousand (R$ 11,941) regarding the acquisition of 7.25% interest in this subsidiary. As a result of this additional interest acquired, the line of non-controlling interests was reduced by the amounts of interest acquired.

g) Net investment hedge

Based on IFRIC Interpretation 16 issued in July 2008, and substantiated by IAS 39, the Company designated as hedge of part of its net investments in subsidiaries abroad the operations of Ten Year Bonds, contracted by the subsidiary GTL Trade Finance Inc., in the amount of US$ 1.5 billion and by the subsidiary Gerdau Trade Inc., in the amount of US$ 1.25 billion, and also loan operations of the subsidiary Gerdau Açominas S.A. in the amount of US$ 701.1 million, which were made in order to provide part of the resources for these investments in acquisitions abroad. Based on the standard and interpretation of standard mentioned above, the Company demonstrated high effectiveness of the hedge as from the debt hiring for acquisition of these companies abroad, whose effects were measured and recognized directly in the statement of Comprehensive Income as an unrealized loss in the amount of R$ 788,007 (gain of R$ 130,750 as of December 31, 2010).

The objective of the hedge is to protect, during the existence of the debt, the amount of part of the Company’s investment in the subsidiaries mentioned above against positive and negative oscillations in the exchange rate. This objective is consistent with the Company’s risk management strategy.

h) Fair value measurement

IAS 32 defines fair value as the amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties in an arm’s length transaction. IFRS 7 establishes a hierarchy of three levels for the fair value, which prioritizes information when measuring the fair value by the company, to maximize the use of observable information and minimize the use of non-observable information. This IFRS describes the three levels of information to be used to measure fair value:

Level 1 - quoted prices (not adjusted) in active markets for identical assets and liabilities.

Level 2 - Inputs other than quoted prices included in Level 1 available, where (non-adjusted) quoted prices are for similar assets and liabilities in non-active markets, or other data that is available or may be corroborated by market data for substantially the full term of the asset or liability.

Level 3 — Inputs for the asset or liability that are not based on observable market data, because market activity is insignificant or does not exist.

As of December 31, 2011, the Company had some assets which the fair value measurement is required on a recurring basis. These assets include investments in private securities and derivative instruments.

Financial assets and liabilities of the Company, measured at fair value and subject to disclosure requirements of IFRS 7 as of December 31, 2011, are as follows:

a) Tax contingencies

a.1) The Company is a defendant in a tax collection action filed by the state of Minas Gerais demanding ICMS tax payments mainly on sales of products to commercial exporters. The updated amount of the action is R$ 59,636. The Company did not record any provision since it considers the tax undue because products for export are exempted from ICMS (state VAT).

a.2) The Company is a defendant in tax collection proceedings seeking ICMS tax payments on the export of semi-finished manufactured products. The total amount is currently R$ 80,218. The Company did not record any provision since it believes that this tax is not owed because its products cannot be considered semi-finished manufactured products.

accounting provision was not made for these demands since its probability for loss is classified as possible by management with the assistance of its legal advisors.

a.6) The Company and its subsidiaries Gerdau Açominas S.A. e Gerdau Aços Longos S.A. are parties to the lawsuits relating to other taxes. The total amount of these lawsuits is R$ 137,959. No provision has been recorded for these lawsuits since they were assessed as possible loss, but nor probable, by management with the assistance of its legal advisors.

b) Civil contingencies

b.1) A lawsuit arising from the representation of two civil construction unions in the state of São Paulo alleging that Gerdau S.A. and other long steel producers in Brazil share customers, thus, violating the antitrust legislation. After investigations carried out by the Economic Law Department (SDE), the final opinion were that a cartel exists. The lawsuit was therefore forwarded to the Administrative Council for Economic Defense (CADE) for judgment.

In May 2004, Gerdau S.A. filed a new lawsuit with the purpose of annulling the administrative proceeding grounded on formal irregularities found in its discovery.

CADE, regardless of the request for submission of negative evidence of cartel made by Gerdau S.A., judged the merits of the administrative proceedings on September 23, 2005 and, by a majority of votes, fined the Company and other long steel producers an amount equivalent to 7% of gross revenues in the year before the Administrative Proceeding was commenced, excluding taxes, for formation of a cartel.

Despite the CADE decision, the legal action filed by Gerdau S.A. follows its normal course and, at present, awaits judgment in the lower court. In the event the procedure irregularities alleged by Gerdau are recognized by the court, the CADE decision may be annulled.

Furthermore, to reverse the terms of the decision by CADE, Gerdau appealed to the Judiciary on July 26, 2006 by bringing a new ordinary suit that not only ratifies the terms of the first suit, but also points out the irregularities found during the course of the administrative proceeding. On August 30, 2006, Gerdau was successful in obtaining legal protection in order to suspend the effects of CADE’s decision until the Judge’s final decision. The judicial guarantee was performed by a bank guarantee corresponding to 7% on the gross income before taxes calculated in 1999 (R$ 245,070).

It should be noted that just prior to the CADE decision, the Public Prosecution Office of the state of Minas Gerais filed a Public Civil Action, based on the above-mentioned SDE decision, and, without mentioning any new elements, alleged that the Company was involved in activities which violated the antitrust legislation. Gerdau S.A. contested this allegation on July 22, 2005.

The Company denies having been part of any type of anti-competitive conduct and believes based on information available, including the opinion of its legal counsel, which the administrative proceeding until now includes irregularities, some of which are impossible to resolve. In relation to the merit, Gerdau is sure that it did not practice the alleged conduct and, supported by the opinion of renowned experts, believes that it is more likely than not to reverse its conviction.

b.2) Civil lawsuit filed by Sul América Seguradora against Gerdau Açominas S.A. and a third party to require acceptance of payment of R$ 34,383 to settle an indemnity claim. The insurance company pleaded doubt in relation to whom payment should be made and alleged that the Company is resisting receiving the payment and settling the matter. These doubts were refuted in the defense and the consigned amount was demonstrated to be insufficient. This was raised in December 2004 and the legal action continues in order to calculate the actual amount due.

Based on the opinion of its legal advisors, the Company´s expectation for loss is remote. It also expects that the ruling will declare the amount payable to be the amount stated in the appeal filed by the Company. Prior to this lawsuit, Gerdau

Açominas S.A. filed a collection lawsuit for the amounts recognized by the insurance company for which it also expects a favorable outcome.

These lawsuits arose from an accident with the blast furnace regenerators on March 23, 2002, which resulted in loss of production, material damages, and loss of profits. In 2002 it sued for indemnities of approximately R$ 110 million based on the costs incurred during the period for equipment downtime and immediate expenses incurred to temporarily recover the equipment. Subsequently, new amounts were added to the dispute, as stated in the Company’s plea, although not yet recorded. The case is still in the hands of the court appointed engineering and accounting experts.

Management considers that the risk of losses from other contingencies affecting the net income of operations or the consolidated financial position of the Company is not more likely than not.

III) Judicial deposits

The Company has judicial deposits related to tax, labor and civil lawsuits as listed below:

a) Post-employment defined benefit pension plan

The Company is the co-sponsors of defined benefit pension plans for almost all employees (“Açominas Plan” and “Gerdau Plan”). Includes the Brazilian plans which are managed by Gerdau - Sociedade de Previdência Privada, a pension entity that provides benefits that supplement the social security benefits of employees and retirees of the Company and subsidiaries in Brazil. The assets of these Plans consist mainly of investments in bank deposit certificates, federal government securities and marketable securities. The Açominas Plan is a plan wholly funded by the entity and its employees contributions and the Gerdau Plan is a plan wholly funded by the entity contributions.

On October 14, 2010, the Company, through Gerdau - Sociedade de Previdência Privada, approved in PREVIC (regulatory public agency for complementary social security in Brazil) the settlement of defined benefit plan (“Plano Gerdau” and “Plano Açominas”), in which the participants have the rights for the benefit settled. All participants of these plans, now settled, were able to: (i) choose to adhere a new defined contribution plan, when it was authorized to transfer the amount related to the individual mathematical reserve from the settled plan for the new plan and add amounts to this reserve trough future contributions and sponsors, plus the profitability resources; or (ii) do not transfer the reserve and maintain the benefit settled in the defined benefit plan, adjusted by the INPC (National Index of Consumer Prices). The new contribution defined plan was developed after analysis on the best complementary social security plans in Brazil, and based on the profile and the employees’ frequent necessities. The main objective is to offer a plan aligned with the market best practices.

Additionally, the Canadian and American subsidiaries sponsor defined benefit plans (Canadian Plan and American Plan) and together they represent North-American Plans that cover substantially all their employees and provide benefits that supplement the retirement benefits for the employees of Gerdau Ameristeel Corporation and its subsidiaries and Gerdau MacSteel. The assets of the Plans are comprised of investments, mainly in marketable securities and these plans are wholly funded.

The assumptions adopted for pension plans can have a significant effect on the amounts disclosed for these plans. Due to the migration process and the closing of Brazilian pension plans, the Company is not calculating the possible effects of changes in discount rates and expected return rate on assets for these plans. The possible effects of changes to the American Plans on the Consolidated Statement of Income are presented below:

|  | 1% Increase |  | 1% Decrease |
Discount rate |  | (3,114 | ) | 3,999 |
Expected return on plan assets |  | (13,196 | ) | 13,189 |

The accumulated amount recognized in Comprehensive Income for employee benefits is R$ (994,105) (R$ (759,458) on December 31, 2010)

Gerdau Ameristeel has an Investment Committee that defines the investment policy for the defined benefit plans. The primary investment objective is to ensure the security of benefits that were accrued under the plans, providing an adequately funded asset pool which is separated and independent of Gerdau Ameristeel Corporation. To accomplish this objective, the fund must invest in a manner that adheres to safeguards and diversification to which a prudent investor of pension funds would normally adhere. Gerdau Ameristeel retains specialized consultants that advice and support Investment Committee decisions and recommendations.

The asset mix policy considers the principles of diversification and long-term investment goals, as well as liquidity requirements. To do this, the target allocation ranges between 60% in shares and 40% in debt securities. The policy also expresses that it will reallocate the assets of the plan when a class of assets reaches the minimum or maximum allocation and that this rebalancing will be done within a reasonable time.

The allocation of the assets of the plan as of December 31, 2011 is demonstrated below:

|  | 2011 |  | 2010 |
Equity securities |  | 52.1 | % | 62.3 | %
Debt securities |  | 40.5 | % | 35.6 | %
Real estate |  | 0.1 | % | 0.2 | %
Others |  | 7.3 | % | 1.9 | %
|  | 100 | % | 100 | %

The table below shows a summary of the assumptions used for both the Company and consolidated to calculate and record the defined benefit plans in 2011 and 2010, respectively:

The expected rate of return on assets is used to determine the increase on the assets of the benefit plans related to the investments expected for the next year. The real rate of return on investments is selected considering the allocation of the assets classes that backing the benefits and the expectations about the return of each investment category. This rate is reviewed annually and eventual changes are incorporated on the medium and long-term economic scenarios.

b) Post-employment defined contribution pension plan

The Extraordinary Shareholders’ Meeting held on April 30, 2003 decided, based on a previously approved plan and within the limit of the authorized capital, to grant preferred stock options to management, employees, or persons who render services to the Company or its subsidiaries, and approved the development of the Long-Term Incentive Program that represents a new method of compensation of the strategic officers of the Company. The options shall be exercised in a maximum of five years after the grace period. The Stock Options Plan establishes that 75% of the options granted to management are exercisable only if they met the performance goals established by the Executive Committee.

The long-term incentive plans costs recognized in the net income was R$ 15,318 on December 31, 2011 (R$ 13,730 and R$ 10,001 on December 31, 2010 and 2009, respectively).

c) Economic assumptions used to recognize costs of employee compensation:

The Company recognizes costs of employee compensation based on the fair value of the options granted, considering their fair value on the date of granting. The Company uses the Black-Scholes model for determining the fair value of the options. To determine fair value, the Company used the following economic assumptions:

The Company settles this employee benefit plan by delivering shares it has issued, which are kept in treasury until the exercise of the options by the employees.

II) Gerdau Ameristeel Corporation — (“Gerdau Ameristeel”)

In February 2010, the Board of Directors of the Company approved the adoption of the Equity Incentive Plan (the “EIP”). Awards under the EIP may take the form of stock options, SARs, deferred share units (“DSUs”), restricted share units (“RSUs”), performance share units (“PSUs”), restricted stock, and/or other share-based awards. Except for stock options, which must be settled in preferred shares, awards may be settled in cash or preferred shares as determined by the Company at the time of grant.

For the portion of any award which is payable in options or SARs, the exercise price of the options or SARs will be no less than the fair market value of a preferred share on the date of the award. The vesting period for all awards (including RSUs, DSUs and PSUs) is determined by the Company at the time of grant. Options and SARs have a maximum term of 10 years.

On March 12, 2010, an award of approximately US$ 11.8 million (R$ 20.8 million) was granted to participants under the EIP for 2010 performance. Gerdau Ameristeel issued 1,728,689 equity-settled SARs, 277,621 RSUs, and 396,602 PSUs under this plan. This award is being accrued over the vesting periods, which consider a period between 4 and 5 years.

On March 16, 2011, an award of approximately US$ 11.2 million (R$ 18.2 million) was granted to participants under the EIP for 2011 performance. The Company issued 1,280,082 equity-settled SARs, 107,286 RSUs, and 214,572 PSUs under this plan. This award is being accrued over the vesting period of 5 years.

In connection with the adoption of the EIP, the Company terminated the existing long-term incentive plan (“LTIP”), and no further awards will be granted under the LTIP. All outstanding awards under the LTIP will remain outstanding until either exercised, forfeited or they expire. On December 31, 2011, there were 2,353,529 cash-settled SARs, 1,140,032 stock options, and 198,769 phantom shares outstanding under the LTIP. This award is being accrued over the vesting period of 4 years.

On August 30, 2010, Gerdau S.A. indirectly acquired all of the outstanding common shares of Gerdau Ameristeel not already owned, directly or indirectly. In connection with the acquisition, all outstanding Options, SARs, PSUs, RSUs, and Phantom Shares were converted to awards in respect of American Depository Receipts of Gerdau S.A. (“ADR”), which represents the right to receive preferred shares of Gerdau S.A. The conversion was based on the relative value of a common share of Gerdau Ameristeel to an ADR as at the closing of the arrangement in order to maintain an equivalent intrinsic value of the award at the time of the exchange. A conversion factor was applied of 0.7993 (the “conversion factor”), equal to the final closing price of a common share of the Gerdau Ameristeel on the New York Stock Exchange (“NYSE”) divided by the closing price of an ADR on the NYSE on August 27, 2010, the last trading day for the Gerdau Ameristeel’s common shares.

All amounts (e.g. grants, exercises, forfeitures, weighted average fair value, fair value, etc.) disclosed in this footnote regarding share-based activity prior to August 30, 2010 (the “modification date”) are on a pre-conversion basis in respect of the Gerdau Ameristeel’s common shares. All amounts disclosed related to activity after the modification date are on a post-conversion basis in respect of ADRs.

Modification expenses for equity-settled awards are recognized if the effect of the modification increases the total fair value of the equity-settled awards or is otherwise beneficial to the employee. The incremental fair value granted is the difference between the fair value of the modified equity award and that of the original award, both estimated at the date of modification. If the modification occurs during the vesting period, the incremental fair value granted is recognized for services received over the remaining vesting period while the original grant date fair value of the original equity award continues to be recognized in accordance with the original vesting period. If the modification occurs after vesting date, the incremental fair value granted is recognized immediately. The modification date fair value of all of the Company’s

equity settled awards was less than the fair value of the original awards at the modification date. As such, no incremental expense was recognized by Gerdau Ameristeel. The modification did not impact the Company’s classification of equity-settled and cash-settled awards.

During the years ended December 31, 2011 and 2010, the compensation costs recognized for all equity-settled awards were US$ 0.8 million (R$ 1.3 million) and US$ 2.7 million (R$ 4.8 million), respectively. The Company recorded compensation expense of US$ (8.6) million (R$ (14.4) million) and US$ 9.3 million (R$ 16.4 million), respectively, related to cash-settled awards for the years ended December 31, 2011 and 2010.

On December 31, 2011 and 2010, the outstanding liability for share-based payment transactions included in other non-current liabilities in the Company’s consolidated balance sheets was US$ 7.7 million (R$ 14.4 million) and US$ 19.9 million (R$ 33.2 million), respectively. The total intrinsic value of share-based liabilities for which the participant’s right to exercise had vested was US$ 3.1 million (R$ 5.8 million) and US$ 5.1 million (R$ 8.5 million) as of December 31, 2011 and 2010, respectively.

Phantom Shares

Phantom Shares provide the holder with the opportunity to receive a cash payment equal to the fair market value of the ADRs. Phantom Shares vest 25% each year over a four year period with the holders receiving payment for vested shares on each grant anniversary date. The holders of Phantom Shares have no voting rights, but accumulate additional shares based on notional dividends paid by Gerdau S.A. on its ADRs at each dividend payment date, which are reinvested as additional Phantom Shares. Compensation expense related to Phantom Shares is recognized over the vesting period based upon the number of shares that are expected to vest and remain outstanding at the end of the reporting period. On the date of grant, the fair value of a Phantom Share is equal to the fair value of the underlying reference shares. For Phantom Shares, the fair value is remeasured at each balance sheet reporting date.

During the year ended December 31, 2010, all Phantom Shares were converted into awards with respect to ADRs (based on the conversion value). This conversion did not have a significant impact on the Company’s consolidated financial statements.

Share Appreciation Rights (SARs)

SARs provide the holder with the opportunity to receive either ADRs or a cash payment equal to the fair market value of the ADRs less the exercise price. The exercise price is set at the closing price of the underlying reference shares on the date of grant. SARs vest over a four to five year period and expire ten years after the grant date. Compensation expense is recognized based on the fair value of the awards that are expected to vest and remain outstanding at the end of the reporting period. The Black-Scholes option pricing model is used to calculate an estimate of fair value. The Company has both equity-settled and cash-settled SARs. For SARs accounted for as equity-settled, the fair value is estimated only at the date of grant. For SARs accounted for as cash-settled, the fair value is remeasured at each balance sheet reporting date.

The grant date fair value of equity-settled SARs granted during the years ended December 31, 2011 and 2010 was US$ 7.04 and US$ 4.56 (R$ 11.79 and R$ 7.64) and the principal assumptions used in applying the Black-Scholes option pricing model were as follows:

|  | 2011 |  | 2010 |
Dividend yield |  | 2.56 | % | 2.77 | %
Volatility in the price of the share |  | 52.75 | % | 60.99 | %
Free rate of return risk |  | 11.85 | % | 12.73 | %
Expected period to maturity |  | 6.51 years |  | 6.51 years |

for the years ended December 31, 2011, 2010 and 2009

(in thousands of Brazilian reais — R$, unless otherwise stated)

The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions. The model requires the use of subjective assumptions. Expected volatility was based on historical volatility of the Company’s stock as well as other companies operating similar businesses. The expected life (in years) was determined using historical data to estimate SARs exercise patterns. The expected dividend yield was based on the historical annualized dividend rates. The risk free interest rate was based on the rate for US Treasury bonds commensurate with the expected term of the granted SARs.

Restricted Share Units (RSUs)

RSUs give the holder the right to receive a specified number of ADRs at the specified vesting date. As determined by the Company, the RSUs vest over a five-year period. The holders of RSUs have no voting rights, but accumulate additional units based on notional dividends paid by Gerdau S.A. on its ADRs at each dividend payment date, which are reinvested as additional RSUs. Compensation expense related to RSUs is recognized over the vesting period based upon the fair value of the RSUs on the grant date and the number of units expected to vest. On the date of grant, the fair value of an RSU is equal to the fair value of the underlying reference shares. The weighted-average grant date fair value of RSUs was US$ 13 and US$ 7.89 (R$ 21.78 and R$ 13.88) for RSUs granted during the years ended December 31, 2011 and 2010, respectively.

During the year ended December 31, 2010, all RSUs were converted to awards in respect of ADRs (based on the conversion factor) which resulted in a weighted-average modification date fair value of US$ 9.87 (R$ 16.45).

Performance Share Units (PSUs)

PSUs give the holder the right to receive one ADR for each unit that vests on the vesting date as determined by the Company. The holders of PSUs accumulate additional units based upon notional dividends paid by the Gerdau S.A. on its ADRs on each dividend payment date, which are reinvested as additional PSUs. The percentage of PSUs initially granted that is exercised depends on the Company’s performance over the performance period against pre-established performance goals. Compensation expense related to each PSU grant was recognized over the performance period based on the fair value of the PSUs on the grant date and the number of units expected to vest. On the date of grant, the fair value of a PSU is equal to the fair value of the underlying reference shares. The weighted-average grant date fair value of PSUs was US$ 13 and US$ 7.89 (R$ 21.78 and R$ 13.88) for PSUs granted during the year ended December 31, 2011 and 2010, respectively.

During the year ended December 31, 2010, all PSUs were converted to awards in respect of ADRs (based on the conversion factor) which resulted in a weighted-average modification date fair value of US$ 9.87 (R$ 16.45).

Stock Options

The Company’s stock options vest over a period of four years. The maximum term of an option is 10 years from the date of grant. On the date of grant, the exercise price of options is based on the fair value of the underlying reference shares.

There were no stock options granted under the EIP during the years ended December 31, 2011 and 2010.

During the year ended December 31, 2010, all of the Gerdau Ameristeel’s stock options were converted to awards in respect of ADRs (based on the conversion factor). Gerdau Ameristeel revalued the original awards at the modification date and also fair valued the new awards at the modification date. Both values were derived using the Black-Scholes option-pricing model. The modification date fair value of the new awards was less than the fair value of the original awards at the modification date. As such, no incremental expense was recognized by Gerdau Ameristeel.

The summary of stock option activity prior to the modification date was as follows ($000s):

III) Gerdau MacSteel Inc. (“Gerdau MacSteel”)

Gerdau MacSteel Inc and its subsidiaries have long-term incentive plans that are designed to reward the Company’s senior management with bonuses based on the achievement of return on capital invested targets. Bonuses which have been earned are awarded after the end of the year in the form of cash or stock appreciation rights (“SARs”). The portion of any bonus which is payable in cash is to be paid in the form of phantom stock. The number of shares of phantom stock awarded to a participant is determined by dividing the cash bonus amount by the market value of the Gerdau S.A. Preferred Share at the date the award of phantom stock is made, based in the average price of Preferred Shares in the New York Stock Exchange. Phantom stock and SAR’s vest 25% on each of the first four anniversaries of the date of the award. Phantom Stock is paid in cash when exercised. An award of approximately US$ 0.8 million (R$ 1.5 million) was earned by participants in 2011 and was granted 41% in SARs, 39% in Performance Shares and 20% in Restrict Shares. In 2010, an award of approximately US$ 1.1 million (R$ 1.83 million) was earned by participants and was granted 44% in SARs, 37% in Performance Shares and 19% in Restrict Shares.

Subsidiary Gerdau MacSteel uses the Black-Scholes pricing method to determine the fair value of stock appreciation rights, recognizing the stock compensation cost as services are provided. The subsidiary used the following economic assumptions to recognize the fair value of these instruments:

Performance shares:

|  | Grant 2011 |  | Grant 2010 |
Dividend Yield |  | 2.56 | % | 2.77 | %
Volatility in the price of share |  | 52.75 | % | 60.99 | %
Free rate of return risk |  | 11.85 | % | 12.73 | %
Expected period to maturity |  | 4.26 years |  | 3.25 years |

The IFRS standard requires that the Company disclose the revenue per product unless the information is not available and the cost to obtain it would be excessive. Additionally, the management does not consider this information useful for its decision making process, because it would aggregate sales for different markets with different currencies, subject to the effects of exchange rate variances. Pattern of steel consumption and price dynamics of each product or group of products in different countries and different markets within these countries are poorly correlated, thus the information would not be useful and would not serve to conclude about historical trends and evolutions. According to this scenario and considering that the information of revenue by product is not maintained on a consolidated basis and the cost to obtain the revenue per product would be excessive comparing to the benefits of the information, the Company does not present the revenue by product.

NOTE 26 — INSURANCE

NOTE 27 — IMPAIRMENT OF ASSETS

The impairment test of goodwill and other long-lived assets is tested based on the analysis and identification of facts or circumstances that may involve the need to perform the impairment test. The Company performs impairment tests of goodwill and other long-lived assets, based on projections of discounted cash flows, which take into account assumptions such as: cost of capital, growth rate and adjustments applied to flows in perpetuity, methodology for working capital determination, investment plans, and long-term economic-financial forecasts.

To determine the recoverable amount of each business segment, the Company used the discounted cash flow method, taking as basis, financial and economic projections to each segment. The projections were updated taken into consideration observed changes in the economic scenario to the market where the Company performs its business, as well as premises of expected results and historical profitability to each segment.

27.1 Goodwill impairment test

The goodwill impairment test allocated to the operating segments is performed annually in December or whenever changes in events or circumstances indicate that the goodwill may be impaired.

The Company has four operating segments, which represent the lowest level in which the goodwill is monitored by the Company. The composition of goodwill by segment is presented in Note 11.

In December 2011, the Company performed an impairment test for the goodwill on the segments and it was not identified impairment loss for the year.

The projection period for the December 2011 cash flows was five years. The premises used to determine the fair value through the discounted cash flow method include: projected cash flow based in the Management estimates to the future cash flows, discount rates and growth rates to the perpetuity determination. Moreover, the perpetuity was calculated considering the stabilization of the operational margins, levels of working capital and investments. The perpetuity growth rate considered was 3% p.a. to the Brazil, Latin America, Special Steels and North America segment.

The discount rates used were determined taking into consideration market information available on the test date. The Company adopted distinct rates to each business segment tested with the objective of demonstrate the differences among the markets in which each segment operate, as well as risk associated to them. The discount rates used were 9.0% p.a. to the North America segment (11.25% in December, 2010), 10.5% p.a. to the Special Steel segment (12.5% in December, 2010), 10.75% p.a. to Latin America segment (12.75% in December, 2010) and 11.0% p.a. to the Brazil segment (13.0% in December, 2010).

Considering the recoverable amount identified through the discounted cash flows, the recoverable amount exceeded the book value in R$ 9,849.8 million to the North America segment (R$ 2,126.7 million in December 2010), R$ 4,295.6 million to the Special Steel segment (R$ 2,738.7 million in December 2010), R$ 1,977.1 million to the Latin America segment (R$ 113.3 million in December 2010), and R$ 7,430.0 million to the Brazil segment (R$ 4,877.7 million in December 2010).

Due to the cash flow potential impact of discount rate and perpetuity growth rate variables, the Company performed a sensitive analysis of changes in these variables. A 0.5% increase in the discount rate to the cash flow of each segment would result in recoverable amounts that would exceed the book value in R$ 8,227.3 million to the North America segment (R$ 1,378.5 million in December 2010), R$ 3,672.8 million to the Special Steel segment (R$ 2,293.2 million in December 2010), R$ 6,032.6 million to the Brazil segment (R$ 3,659.1 million in December 2010) and R$ 1,502.5 million for Latin America segment (recoverable amount lower than the book value in R$ 182.8 million in December 2010).

On the other hand, a 0.5% decrease in the perpetuity growth rate in the discounted cash flow to each segment would result in recoverable amounts that would exceed the book value in R$ 8,636.2 million to the North America segment (R$ 1,646.3 million in December 2010), R$ 3,866.0 million to the Special Steel segment (R$ 2,444.2 million in December 2010), R$ 6,467.8 million to the Brazil segment (R$ 4,072.9 million in December 2010) and R$ 1,645.1 million for Latin America segment (recoverable amount lower than the book value in R$ 74.9 million in December 2010).

It is important to mention that events or significant changes in the panorama may result in relevant impairment of goodwill. As main risks, an eventual deterioration in the steel market, relevant downturn in the automotive and civil construction sectors, stoppage of industrial units of the Company and relevant changes in the economy or financial market that result in increase in the risk perception or reduction in the liquidity and refinancing capacity.

27.2 Other long-lived assets Impairment test

In the fourth quarter of 2010, due to the interruption of activities in one of the plants and mainly due to the lack of expectation to restart the operations on this unit, the tests identified impairment on Special Steel plant in the amount of R$ 68,008.

In addition, in the fourth quarter of 2010, the Company also in the special steel segment reversed Impairment due to restart the production process in one unit, which had impairment losses recognized in 2009, totaling R$ 218,391. The recoverable amount on fixed assets was defined based on present value, with a discount rate used on impairment test of 12.5% (13.30% in December 2009), in a total of R$ 188,163. The losses and the reversal of recognized losses on fixed assets were recognized in the account “Reversal of impairment (impairment) of assets” in the consolidated income statements.

In the fourth quarter of 2010, also in the Special Steel segment, the Company reversed impairment losses for other intangible assets, due to the reestablishment of the customer relationships value because of the resumption of automotive industry demand, which suffered impairment recognized in 2009, in a total of R$ 304,425. The impairment tests for other intangible assets identified the need to reverse this impairment in a total of R$ 216,191, which is based on the recovery of their customer portfolio, related to the automotive industry. The other intangible assets recoverable amount is their value in use and the discount rate used on the impairment test for 2010 was 12.50% (13.3% in December 2009). The losses and the reversal of recognized losses on other intangible assets were recognized in the account “Reversal of impairment (impairment) of assets” in the consolidated income statements.

In December 2011, the Company has not identified impairment loss for other long-lived assets for the year.

Despite the circumstances considered in the test indicates an improvement in the economic and steel context, futures uncertainty in the market remain. Therefore, the Company believes that the scenarios used in the impairment test, performed in December are the best estimate for the results and future cash generation for each segment. The Company will continue to monitor the results in 2012, which will indicate the reasonableness of future projections utilized.
